Description

Technical Field

[0001] The invention relates to the technical field of reservoir water discharge, in particular to an air replenishing mechanism for a reservoir water discharge facility. Background Art

[0002] A reservoir is a man-made water conservancy facility, mainly used for storing water resources, regulating river flow, supplying drinking water, irrigating farmland, generating electricity and flood control. Reservoirs usually build dams on rivers to form a closed water body, which is called a reservoir. Reservoirs can be classified according to their size, purpose and geographical location. Water release from reservoirs is generally carried out through water pipes.

[0003] Chinese patent CN219059961U discloses a pre-air replenishing mechanism for a flood discharge gate, comprising a vertical plate and a horizontal plate arranged on one side of the vertical plate, a diversion assembly connected to the gate is arranged below the horizontal plate, an adjusting motor for adjusting the rotation of the diversion assembly on a vertical plane is installed on the horizontal plate, a top plate is fixedly connected to the top of the vertical plate, a hydraulic cylinder for driving the horizontal plate to move up and down is installed on the top plate, and an aerator for supplying air to the diversion assembly is installed on the horizontal plate; the height and swing angle of the diversion assembly can be adjusted by the arranged hydraulic cylinder and the adjusting motor, which increases its flexibility when used in conjunction with the gate, and a plurality of diversion pipes are arranged in the diversion assembly, so that the air replenishment into the gate can be more uniform.

[0004] The above patent improves the shortcomings of the prior art pre-air supply mechanism, which has poor flexibility and cannot adapt well to the gate movement when the gate moves. However, this technical solution only focuses on pre-gate air supply. When the height of the reservoir discharge pipe outlet is lower than the height of the working valve, negative pressure will appear in the part behind the discharge pipe valve when releasing water, causing turbulence in the water flow in the discharge pipe, thereby causing the water pipe to vibrate, which may seriously damage the corresponding facilities. The present application proposes an improvement on this shortcoming. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an air replenishing mechanism for a reservoir discharge facility, which has the advantage of preventing the discharge pipe from vibrating when discharging water. It solves the problem in the prior art that the height of the discharge pipe outlet is lower than the height of the working valve, and negative pressure will appear in the part behind the discharge pipe valve when discharging water, causing turbulence in the water flow in the discharge pipe, thereby causing the water pipe to vibrate, which may damage the corresponding facilities in serious cases.

[0006] To achieve the above object, the present invention provides the following technical solution: an air supply mechanism for a reservoir water discharge facility, comprising a water discharge pipe, an air intake pipe is fixedly installed on the surface of the water discharge pipe, and an air intake mechanism is provided on the air intake pipe;

[0007] The air intake mechanism includes a mounting ring fixedly mounted on the inner side of the air intake pipe, an air intake turbine is rotatably mounted on the inner side of the mounting ring, a connecting rod extending into a drain pipe is fixedly mounted on the bottom of the air intake turbine, a driving wheel is fixedly mounted on the bottom of the connecting rod, and an air intake pipe sealing assembly is provided between the drain pipe and the air intake pipe.

[0008] Furthermore, the air intake pipe sealing assembly includes a hollow cylinder fixedly mounted on the surface of the drain pipe, a fixed rod extending to the outer surface of the hollow cylinder is rotatably mounted inside the hollow cylinder, a sealing cover is fixedly mounted on one end of the fixed rod, a pull rope extending into the drain pipe is fixedly mounted on one end of the fixed rod away from the sealing cover, a moving block is fixedly mounted on one end of the pull rope, a sealing cover reset assembly is provided between the fixed rod and the air intake pipe, and a limiting assembly is provided between the moving block and the drain pipe.

[0009] Furthermore, a strip-shaped hole is opened on the surface of the hollow cylinder, the fixing rod is located in the strip-shaped hole, and the surface of the fixing rod is rotationally connected to the inner surface of the strip-shaped hole.

[0010] Furthermore, a pulley rotates inside the hollow cylinder, and the pull rope is in contact with the pulley.

[0011] Furthermore, the sealing cover reset assembly includes a connecting plate fixedly mounted on the outer surface of the air intake pipe, a tension spring is fixedly mounted on the upper surface of the connecting plate, and the top of the tension spring is fixedly connected to the surface of the fixing rod.

[0012] Furthermore, a telescopic sleeve is fixedly installed between the upper surface of the connecting plate and the surface of the fixing rod, and the tension spring is located inside the telescopic sleeve.

[0013] Furthermore, the limiting assembly includes a T-shaped groove opened on the inner surface of the drain pipe, and a T-shaped block that is clamped into the T-shaped groove is fixedly installed on the surface of the moving block.

[0014] Furthermore, an inclined panel is fixedly mounted on the surface of the moving block.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The air replenishing mechanism for the water discharge facility of the reservoir is provided with a mounting ring in the air intake pipe, an air intake turbine is provided on the mounting ring, and a connecting rod and a driving wheel are provided on the air intake turbine. When in use, the driving wheel can be driven to rotate by the water flow in the water discharge pipe, and then the driving wheel can drive the connecting rod and the air intake turbine to rotate. The air intake turbine is used to draw external air into the water discharge pipe, so that the air pressure in the water discharge pipe is kept balanced, thereby preventing the water discharge pipe from vibrating. This solves the problem in the prior art that the height of the water discharge pipe outlet is lower than the height of the working valve, and negative pressure will appear in the part behind the water discharge pipe valve when draining water, causing turbulence in the water flow in the water discharge pipe, thereby causing the water pipe to vibrate, which will damage the corresponding facilities in severe cases.

When in use, the moving block is moved by flowing water, and the sealing cover is opened by pulling the pull rope through the movement of the moving block, so that air can be admitted to the air intake pipe. When the air intake pipe is not in use, the air intake pipe can be closed to prevent debris from falling into the air intake pipe and the discharge pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] A sealing cover reset assembly is provided between the fixed rod 8 and the air intake pipe 2. The sealing cover reset assembly includes a connecting plate 14 fixedly mounted on the outer surface of the air intake pipe 2. A tension spring 15 is fixedly mounted on the upper surface of the connecting plate 14. The top of the tension spring 15 is fixedly connected to the surface of the fixed rod 8. The sealing cover reset assembly can be used to cover the air intake pipe 2 after the water is drained. A telescopic sleeve 16 is fixedly mounted between the upper surface of the connecting plate 14 and the surface of the fixed rod 8. The tension spring 15 is located inside the telescopic sleeve 16.

[0029] The working principle of the above embodiment is:

[0030] During use, after water flows into the drain pipe 1, the water flow will impact the driving wheel 6, causing the driving wheel 6 to rotate, and then the driving wheel 6 drives the connecting rod 5 and the intake turbine 4 to rotate. At the same time, the water flow impacts the moving block 11, and under the action of the inclined panel 19, the moving block 11 moves in the drain pipe 1, and then the moving block 11 pulls the pull rope 10, so that the fixed rod 8 moves downward away from one end of the sealing cover 9, and then the sealing cover 9 can be tilted up and opened, so that the intake pipe 2 is in an open state. The pulley 13 can make the pull rope 10 move and retract more smoothly. When the sealing cover 9 is tilted up and opened, the tension spring 15 is stretched. When there is no water in the drain pipe 1, the tension spring 15 pulls the fixed rod 8, so that the sealing cover 9 covers the top of the intake pipe 2 again.
