Description

Improved outdoor ground fire hydrant and its working method

Technical field:

The present invention relates to a new type of structure, brand-new opening and closing methods and appearance of fire hydrants, so that it has upward expansion space, can be equipped with additional equipment, and then endows outdoor ground fire hydrants with more functions and a more beautiful appearance .

Background technique:

The development of China has attracted the attention of the world, and the urban construction is changing with each passing day. The supporting landscape construction, urban beautification and lighting construction of the city are even more pleasing to the eye. But as we all know, the existing fire hydrants are simple in appearance and have single functions, and it is difficult to integrate with the urban beautification construction that the country is vigorously advocating. It is necessary to give the existing outdoor ground fire hydrants more practical functions and a more fashionable and beautiful appearance.

The current outdoor ground fire hydrants need to be twisted and opened from the top of the fire hydrant, so that it is impossible to expand the space and install additional equipment on the top of the fire hydrant, so that it is impossible to expand functions and install additional equipment without increasing the occupied area. It is also difficult to achieve a cosmetic appearance.

At present, the country is vigorously developing functional urban infrastructure, beautifying the image of the city, building a smart city, and striving to improve the level of urban management and service, which requires that outdoor ground fire hydrants that can be seen everywhere must be endowed with more functions and a more fashionable and beautiful appearance. And it is necessary to expand the space of outdoor ground fire hydrants in order to install more equipment.

At present, the fire hydrant opened from the top can only be installed next to it in order to expand the space or install large-scale equipment. In this case, it will occupy a large area. . Moreover, the outdoor ground fire hydrant is located low or even installed among bushes and weeds, so many functions are inconvenient to realize, such as solar energy storage photovoltaic panels, or the sign that there is a fire hydrant here can be easily recognized from a distance, etc.

Detailed ways:

Below in conjunction with embodiment the method of the present invention is described in further detail. It should be noted that the protection scope of the present invention shall include but not be limited to the technical content disclosed in this embodiment.

The improved outdoor ground fire hydrant of the present invention includes an upright body 1 and a valve stem 2 erected in the body 1 which can be moved up and down. The water outlet 5 and the third water outlet 6. The water inlet 3 is provided with a water-stop pad 7 connected to the lower end of the valve stem 2 for blocking the water inlet. The side of the body 1 is provided with a horizontal opening and closing knob. Rod 8, the inner end of the horizontal opening and closing rotary rod 8 is provided with a gear 10 that meshes with the rack 9 on the inner side wall of the valve stem, and the outer end of the horizontal opening and closing rotary rod 8 protrudes out of the body. In the present invention, the first and second water outlets are water outlets of specification 65, and the third water outlet is a water outlet of specification 100. An anti-freeze drainage hole is provided above the water-stop pad.

Further, for stable and reliable lifting, the middle section of the valve stem is arcuate, and the rack 9 is arranged at the concave side wall of the arcuate section.

Further, in order to lift smoothly, a bracket 11 for supporting the valve stem is provided on the upper and lower parts of the above-mentioned body, and the middle part of the bracket is provided with a square hole 12 for limiting the valve stem; the four inner sides of the above-mentioned square hole The walls are all provided with a bearing 13 whose wheel surface abuts against the surface of the valve stem. Bearings are used so that the bow stem can move up and down more freely and quickly. The bow-shaped valve stem adopts a square body and a bracket with a square hole to prevent the bow-shaped valve stem from swinging left and right when it moves up and down.

Further, in order to facilitate the rotation, the outer end of the above-mentioned horizontal opening and closing rotary rod is provided with an inner pentagonal notch 14, so as to facilitate the insertion and rotation of the wrench. The structure of the horizontal opening and closing rotary rod and the bow-shaped square valve stem can be designed with a fixed clip according to the needs, so that the valve stem can be fixed at any position and prevent the water-stop pad from being washed away under the action of water pressure.

The working method of the improved outdoor above-ground fire hydrant of the present invention includes an upright body and a valve stem vertically installed in the body, which can be moved up and down. and the third water outlet, the water inlet is provided with a water-stop pad connected to the lower end of the valve stem for blocking the water inlet, the side of the body is longitudinally provided with a horizontal opening and closing rotary rod, and the horizontal opening and closing The inner end of the rotary rod is provided with a gear that meshes with the rack on the inner wall of the valve stem, and the outer end of the horizontal opening and closing rotary rod extends out of the body; when working, use a tool to rotate the horizontal opening and closing rotary rod clockwise to make the horizontal The gear at the inner end of the opening and closing rotary rod drives the rack, the valve stem and the water stop pad at the lower end of the valve stem to rise, the water inlet is opened, and the water can enter the body, and can be drained from the first water outlet and the second water outlet. and the third water outlet. When a wrench is used to open and close the rotary rod counterclockwise horizontally, the gear of the horizontal open and close rotary rod acts on the rack of the bow-shaped square valve stem, so that the valve stem is lowered, and the water-stop pad at the lower end of the valve body is also lowered, so that Control the flow rate and flow rate of the water in the pipeline to the fire hydrant body until it is completely closed.

The device of the present invention is ingenious in conception, high in feasibility, easy to understand and economical in use, and effectively solves the single opening mode and opening position of the existing outdoor ground fire hydrant, so that the space of the outdoor ground fire hydrant can be expanded upwards, additional equipment can be installed, and further It can change the current situation of single function and simple appearance of existing fire hydrants; maximize the additional functions of fire protection facilities, promote urban beautification, build smart cities and strive to improve urban management and service levels, and efficiently promote the sound development of fire protection. , To escort the healthy operation of the national economy.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
