Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repeater (automatic repeater) used for fire fighting radio.

[0002]

2. Description of the Related Art FIG. 4 shows an outline of a radio condition when a conventional device is used.
Shown in In the conventional technology, the radio wave 7 is used to communicate with the firefighter 3 and the fire engine 4 at the fire extinguishing site. I was taking it.

[0003]

However, usually,
Fire extinguishing work is performed at a distance of about a hundred and a dozen meters from the fire engine. At that time, firefighters request increase or decrease in water pressure and water volume as the fire extinguishing work progresses.

Conventionally, communication is carried out wirelessly, but there is a wide variety of fire extinguishing sites, and there is a drawback that radio waves do not reach inside buildings or underground.
An object of the present invention is to provide a repeater for fire fighting radio that can solve these problems.

[Means for Solving the Problems]

(First Means) A repeater for fire-fighting radio (automatic repeater) according to the present invention comprises: (A) a signal part including an antenna for transmitting a signal, a transmitter and a receiver; and (B) power to the signal part. Consisting of a battery to be supplied and a (C) generator,
(D) The antenna, the transmitter, and the receiver for transmitting the signal of the signal unit are attached to the outside of a cylinder that can be attached to and detached from a hose. (F) The generator comprises a propeller having a permanent magnet and a coil attached to face the permanent magnet, the propeller being provided inside a fire radio repeater connected to a hose, and the permanent magnet. The coil is used to generate electric power by utilizing the water flow in the hose and store the electric power in a battery to enable continuous work for a long time.

Therefore, the following action (a radio wave shielding avoidance action by the device of the present invention) is performed. As shown in FIG.
The radio wave 7 emitted by the firefighter side of the fire extinguishing site is sent to the antenna 1
1 is received by the receiver 12 of the nearest repeater 8.

The transmitter 13 of the peter 8 transmits this.
On the other hand, the signal emitted from the fire engine side is transmitted in the opposite direction to the signal, and is transmitted from the transmitter 13 of the repeater 8 to the wireless device 5
Received at.

By performing this operation by one or a plurality of units up to the side of the fire engine, it is possible to make contact even in a place where visibility is poor and radio waves cannot reach. On the other hand,
A propeller 17 provided inside a fire radio repeater 8 connected to the hose 6, a permanent magnet 18, and a coil 19
The electric power is generated by the power generation mechanism utilizing the water flow in the hose and stored in the battery 14 to enable continuous work for a long time.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) FIG. 1 shows a first embodiment of the present invention.
~ Shown in FIG. FIG. 1 is a schematic diagram of a device configuration according to a first embodiment of the present invention, FIG. 2 is a schematic diagram of a structure of a generator according to the present invention, and FIG. 3 is a wireless state when the device of the present invention is used. FIG.

As shown in FIGS. 1 to 3, the radio wave 7 emitted from the firefighter side of the fire extinguishing site is received by the receiver 12 of the nearest repeater 8 through the antenna 11. further,
The transmitter 13 of the repeater 8 transmits the received signal again through the antenna 11.

By carrying out this with one unit or a plurality of units, the communication between the firefighter 3 and the fire engine 4 at the fire scene is established. Since fire extinguishing work is expected to take a long time, each repeater 8 stores electricity in the battery 14 by the propeller 17 provided in the flow passage in the hose 6 and the generator 15 connected to the propeller 17.

The fire-fighting radio repeater 8 includes a traffic signal unit including an antenna 11 for transmitting signals, a transmitter 13 and a receiver 12, and a battery 14 for supplying electric power to the traffic signal unit.
It is composed of a generator 15.

Antenna 11 for transmitting the signal of the traffic signal section
, The transmitter 13 and the receiver 12 have the same diameter as the hose 6,
It is attached to the outside of a cylinder 21 that can be attached to and detached from the hose 6. Further, the generator 15 includes a propeller 17 having a permanent magnet 18 on the outer peripheral portion of the tip provided in the water passage of the cylinder 21, and a permanent magnet 1
8 and a coil 19 attached so as to face each other.

The rectifier 16 is a rectifier for the water flow entering the propeller 17 provided on the water flow inlet side of the propeller 17. Further, the bearing 20 is a propeller 1 which is a rotating part.
Supports 7.

[0015]

Since the fire fighting radio repeater according to the present invention is constructed as described above, it has the following effects. (1) It is possible to overcome the drawback that radio waves do not reach due to the shadow of buildings such as buildings. Therefore, work such as messenger is unnecessary. (2) Since the electric power of the traffic signal can be obtained by utilizing the water flow in the hose, the battery can be made smaller and lighter.
