Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a reservoir flood discharge safety protection net. Background Technique

[0002] A reservoir is an artificial lake formed by building a dam across a mountain valley or a narrow part of a river, which can be used for irrigation, power generation, flood control and fish farming. A spillway is a flood control device for water conservancy buildings such as reservoirs, mostly built on one side of the dam, like a large trough. When the water level in the reservoir exceeds the safety limit, the water flows downstream from the spillway to prevent the dam from being damaged. Therefore, it is necessary to discharge the water inside the reservoir.

[0003] When the water inside the reservoir is discharged, it is necessary to cover the drainage trough of the sluice with a protection net to prevent the fish inside the reservoir from escaping. However, when the existing protection net is in use, due to the strong water pressure during the flood discharge process, the protection net deforms due to the water pressure, so there is a phenomenon that the flood discharge is not safe enough, and thus improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a reservoir flood discharge safety protection net, which has the effect of reducing the deformation of the protection net caused by water pressure.

[0005] The above technical purpose of the utility model is achieved by the following technical scheme: a reservoir flood discharge safety protection net, including a sluice, both sides of the top of the sluice are fixedly connected with connecting plates, the outside of the connecting plates is fixedly connected with motors, the output ends of the motors are fixedly connected with drums, a chain is arranged outside the drums, a protection plate is arranged at the bottom of the chain, a rotating shaft is fixedly connected inside the sluice, the rotating shaft is rotatably connected inside the protection plate, a cavity is opened inside the protection plate, sliding rails are fixedly connected to both sides of the cavity, sliders are slidably connected inside the sliding rails, a protection net is fixedly connected to one side of the sliders, a gap is arranged between the sliders and the protection plate, and a first spring is fixedly connected inside the gap.

[0006] By adopting the above technical solution, the staff starts the motor, so that the motor drives the chain to wind through the roller. The bottom of the protection plate is rotationally connected to the inner side of the sluice through a rotating shaft, and the top of the protection plate is connected to the chain. Thus, when the chain winds, the protection plate will rotate around the rotating shaft, and then the protection plate can be closed at the drain opening of the sluice. The protection net covers the inside of the protection plate through the cavity. During the drainage process of the sluice, water passes through the inside of the protection net. In this process, the pressure generated by the water will cause the protection net to displace. The protection net is slidably connected to the inside of the slide rail through a slider. At the same time, during the displacement of the protection net, it contracts through the first spring, and then can buffer the pressure borne by the protection net. Through the contraction of the first spring and the movement of the protection net, it can greatly prevent the protection net from deforming due to the water pressure.

[0007] A further setting of the present utility model is that: a hook is fixedly connected to the bottom of the chain, and suspension rings are fixedly connected to both sides of the top of the protection plate.

[0008] By adopting the above technical solution, the hook is fixed at the end of the chain, and the suspension rings are fixed on both sides of the top of the protection plate. The hook is hung inside the suspension ring, so that the chain can be connected to the protection plate.

[0011] A further setting of the present utility model is that: the number of the mounting plates is two, and four bolts are threadedly connected to the inside of each mounting plate.

[0012] By adopting the above technical solution, the two mounting plates are distributed at the edges of the outer side of the protection plate, and a total of eight bolts are threadedly connected to the inside of the two mounting plates.

[0013] A further setting of the present utility model is that: a piston rod is fixedly connected to the outer side of the mounting plate, a piston cylinder is sleeved at the bottom end of the piston rod, and a piston is fixedly connected to the bottom end of the piston rod.

[0014] By adopting the above technical solution, after the sluice discharges flood, through the unwinding of the chain, the protection plate is laid flat in the dam, and then the sundries and dead fish inside the protection plate and the protection net can be cleaned. During this process, the piston cylinder supports the bottom of the protection plate, and the piston rod performs piston movement inside the piston, and can buffer the pressure borne by the dam.

[0015] A further setting of the present utility model is that a first buffer plate is fixedly connected to the bottom of the piston cylinder, a second spring is fixedly connected to the bottom of the first buffer plate, and a second buffer plate is fixedly connected to the bottom of the second spring.

[0016] By adopting the above technical solution, the second buffer plate contacts the dam, the second spring is arranged in the gap between the second buffer plate and the first buffer plate, and through the contraction of the second spring, the pressure borne by the dam can be buffered again.

[0017] A further setting of the present utility model is that the number of the second springs is several, and the several second springs are distributed in a form of annular array.

[0020] By adopting the above technical solution, through the arrangement of the anti-slip layer, the friction between the second buffer plate and the dam can be increased.

[0021] A further setting of the present utility model is that anti-slip particles are fixedly connected to the outside of the anti-slip layer, and the number of the anti-slip particles is several.

[0022] By adopting the above technical solution, through the arrangement of multiple anti-slip particles, the bottom of the anti-slip layer can have a grip.

[0023] A further setting of the present utility model is that the number of the slide rails is two, and the two slide rails are symmetrical to each other.

The protection net 10 covers the inside of the protection plate 6 through the cavity. During the drainage process of the sluice gate 1, water passes through the inside of the protection net 10. During this process, the pressure generated by the water will cause the protection net 10 to displace. The protection net 10 is slidably connected to the inside of the slide rail 8 through the slider 9. At the same time, during the displacement of the protection net 10, it contracts through the first spring 11, and then can buffer the pressure borne by the protection net 10.
