Problems solved by technology

[0003] In the equipment of these enterprises, the pump station is generally used to enter the water through the water intake. During this process, swimming animals such as fish will enter the pump station with the water intake, resulting in death. On the one hand, the amount of resources in the adjacent waters will be reduced. Rot pollutes the ecological environment, on the other hand, it may also cause damage to the pumping station system

Embodiment Construction

[0032] Such as Figure 1~5 Shown, a kind of bubble curtain generating device for protecting aquatic animals is characterized in that it comprises an air supply system composed of an air compressor 1 and an air tank 2 (compressed air generated in the air compressor 1 enters the air tank 2) Connected with the air tank 2, the exhaust pipe 4 is arranged in the waters outside the water intake, and the end of the exhaust pipe 4 near the air tank 2 is equipped with a control system 3, and the exhaust pipe 4 is provided with vent holes 8 at intervals.

[0033] Such as image 3 , 4 As shown, the device is arranged in two rows or more than two rows of exhaust pipes 4 in the waters outside the water intake. Exhaust pipe 4 adopts more than two rows, can exhaust simultaneously to increase the width of air foam, and can also be used as a mutual backup to prevent another row of exhaust pipe 4 from going wrong. Such as Figure 3-5 As shown, the exhaust hole 8 is an exhaust pipe, or a dril...

Abstract

The invention relates to a bubble curtain generating device for protecting aquatic animals and a method thereof. The bubble curtain generating device comprises an air supply system formed by an air compressor and an air tank, and exhaust pipes which are connected with the air tank and are arranged in a water area at the outer side of an intake, wherein one end of each exhaust pipe close to the air tank is provided with a control system, and exhaust holes are arranged in the exhaust pipes at intervals. Two rows or more rows of exhaust pipes can be arranged, a protecting frame is arranged outside each exhaust pipe, and a lower water box is arranged at the tail end of each exhaust pipe. The control system has continuous / pulsed / intermittent air supply methods. The design method comprises the following steps of determining a layout range and the overall shape of a water bottom, designing the control system, selecting the air compressor and the air tank and the like. The device provided by the invention has the advantages of simple structure, easiness in installation, convenience in use and obvious effects. The compressed air generated by the air compressor is stored into an air storage tank, the air supply pressure and the air supply amount are adjusted by the control system, and the air is exhausted by the exhaust pipes arranged at the water bottom of the water area at the outer side of the intake to generate a bubble curtain in water to prevent fish from swimming forwards, thereby effectively preventing the fish from being sucked into the intake to cause deaths.

Description

technical field [0001] The invention relates to a bubble curtain generating device and a method thereof, in particular to a bubble curtain generating device and a method for protecting aquatic animals. Background technique [0002] my country is a country with a large energy demand and consumption, among which the thermal power installed capacity exceeds 6 trillion kilowatts, and there are nearly 60 thermal power plants with a level of tens of millions. At present, my country has 11 nuclear power plants. By 2020, about 30 units of one million kilowatts of nuclear power plants will be built in coastal areas. , nuclear power generation in 2011 was 87.4 billion kilowatts. Thermal power plants and nuclear power plants need a large amount of cooling water to be continuously supplied due to the needs of providing heat and cold sources and various cooling needs. A thermal power plant with a condensing unit of one million kilowatts needs about 30m3 / s of cooling water; a nuclear powe...
