Definitions

  • the outlet is located between the upper and lower pools of the dams in the form of ledges, which are monolithic blocks, as in Fig. 1, where the water deceleration at high pressure of the H-dams is provided by tightly interconnected, tight with respect to atmospheric pressure , trays, 1.5 m long.
  • Diaphragm hydraulic units (8) are located, as in Fig. 3 and 4, by ledges through two blocks, but so that the level of the inlet barred hole (10) falls on the upper level of the storage (derivative) capacity (7).
  • System operation Water from the upstream level through barred openings (10) through low pressure pipes (11), buried below the freezing level of the soil, enters the derivation tank (7), which is filled with water to the level of water intake in the upstream, which is the source of water supply to the membrane hydraulic unit (8). Its operation, having lost the energy of 1.5 m (or 3 m) of pressure, flows smoothly at the exit of the last tray from the sprayer (12).
  • One such tray in the cross section of the passage opening provides a water speed of about 3.5 m / s, but due to a flooded jump at the entrance of the same tray, the speed drops to 1 m / s and, connecting with the pressure at the level the lower end of the air tubes in the cross section of the outlet of the tray, the speed increases to 2m / s
  • the next tray is done without a bottom ledge, and the lower ends of the feedback tubes are located only 4-5 cm above the upper edge of the pouring hole of the tray.
  • the fish passage consists of a series of sequentially placed, docked blocks, consisting of the above trays and a braking platform for water and rest for fish.
  • the total length of such a block is 22 m
  • the slope of the active lift is 1: 8, which meets the requirements.
  • Such a block can be used on dams of 3–4 meters in height.
  • Water consumption can be estimated relative to the discharge at the hydroelectric power station. According to Luzanskaya D.I., the discharge during the winter months of the Samara hydroelectric station is 5 -7 m from the average reservoir level of 9 m with an area of 644,000 ha. We take a five-meter drawdown, then the flow rate at the hydroelectric power station will be approximately 32.2 km per cubic meter.
  • Fig. l shows in section two trays for pairing the fish passage with the river at the upper tail, 8 trays of the block with a mini-pool and the main dimensions.
  • Figure 2 shows a top view of the fish passage, and only two water-stabilizing tanks are shown because of their identity and their possible location on opposite sides of the trays.
  • the first two trays will probably be required to connect the fish passage to the river channel at the upper pool through a small artificial backwater due to the presence of station facilities and therefore the location of the axis of the fish passage at an angle to the axis of the river's watercourse. This, moreover, will facilitate the task of combating getting into the fish pass fuel, ice and other sediments.
  • the speed of the jet in the trays can be reduced by a quarter or even more (for example, with 3 nodes MT- by 6%, with 6 nodes — by 12%, with 12 nodes-at 24% and so on).
  • the essence of the invention is to create, based on the well-known hydraulics, a water outflow circuit with a constant speed of an acceptable size and cost hydraulic structure, which provides a constant water speed of up to 2 m / s, which sturgeons with respite every 15 m of climb can overcome bypassing dams of hydroelectric power stations of any pressure at full the absence of adverse factors that scare away the fish due to its biological characteristics, as well as apply the property of a membrane hydraulic unit not only to convert potential energy into s in torque, but use losing potential energy of the water pressure as the factor of the additional braking.

Abstract

L'invention concerne une passe à poissons destinée aux asipenséridés, fonctionnant avec des goulottes étanches et utilisant le déclenchement d'appareils hydrauliques à membrane, qui respecte toutes les conditions nécessaires pour le passage des asipenséridés compte tenu de leurs capacités physiques et biologiques en période de frai. L'appareil hydraulique à membrane utilisé dans le système de freinage d'eau à l'intérieur de la passe à poissons assure un ralentissement de l'accélération du jet d'eau d'environ 25 % et permet en outre d'augmenter la production d'énergie électrique; par exemple, avec une hauteur de chute H = 30 (centrale hydroélectrique de Samara), l'augmentation s'élève à 15,768 trillions de kilowattheures par an (contre 11 trillions de kilowattheures actuellement; de plus, cette augmentation concerne chaque mois et non pas cinq ou six mois par an, comme c'est le cas des centrales hydroélectriques à turbines modernes); il s'agit donc d'une augmentation de 1500 fois, avec de plus une consommation d'eau 700 fois moindre.
