In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0030] Referring to Figures 1-4 , a water conservancy construction waterproof structure, including support 1, the support 1 is provided with gate opening and closing mechanism, the drive end of the gate opening and closing mechanism is installed with gate 2, the gate 2 is adapted with support 1, the gate opening and closing mechanism can drive the gate 2 moves up and down to control the opening and closing of support 1, when the gate 2 is moved to the position, support 1 is closed to realize waterproof, the gate 2 is fixedly penetrated with drain pipe 3, the drain pipe 3 is provided with ball valve 4, the valve stem 13 outer end of ball valve 4 is installed with connecting rod 5, the other end of connecting rod 5 is installed with float 6, the side away from gate 2 of float 6 is installed with intercepting net 7.

[0031] The device is used, the intercepting net 7 is arranged on the side away from the gate 2 of the float 6, when the float 6 is rotated and raised by the water body buoyancy, the ball valve 4 is driven to open, the water body is discharged through the ball valve 4 and the drain pipe 3, at the same time, the intercepting net 7 can directly intercept the branches, plastics and other floating garbage carried in the water flow, effectively avoid that the garbage enters the inside of the drain pipe 3 with the water flow, so that the continuous smoothness of the drain pipe 3 under the condition of unattended is guaranteed.

[0032] Compared with the prior art, the linkage layout of the intercepting net 7 and the float 6 in the device forms a double anti-blocking mechanism of "physical interception + water level triggering": the intercepting net 7 blocks bulk materials, and the float 6 automatically opens and closes the ball valve 4 according to the water level change to drain water, effectively preventing the internal blocking risk caused by the instantaneous large drainage volume.

[0033] As a preferred example of the present application, the intercepting net 7 is arc-shaped, including an outer frame and a stainless steel mesh connected to the inner circumference of the frame.

[0034] Specifically, the intercepting net 7 adopts an outer arc design, forming a centrally convex flow guide curved surface, which can guide the floating garbage (such as leaves, plastic bags) in the water flow to the outer periphery of the mesh, avoiding the garbage from colliding with the gate 2 along the straight water flow or accumulating in the mesh; the curved surface tension of the outer arc mesh can disperse the water flow impact force, reducing the risk of deformation of the frame due to excessive local stress, especially suitable for high flow rate water conservancy scenarios; in addition, the outer frame can be integrally formed with high-strength metals such as galvanized steel or aluminum alloy, and is connected with the inner periphery of the mesh through bolts, which not only ensures the overall rigidity of the arc structure, but also can resist the instantaneous impact of large debris (such as branches, stones) in the water flow, avoiding tearing of the mesh or breaking of the frame. The outer arc design makes the intercepting net 7 form an arch stress distribution when stressed, compared with the flat intercepting net 7, the compressive strength is effectively improved, and the service life in harsh environments is prolonged.

[0035] As a preferred example of the present application, the end of the connecting rod 5 away from the ball valve 4 is fixedly connected with the center position of the side of the floating block 6, the floating block 6 is spherical, and the material can be corrosion-resistant engineering plastic (such as polytetrafluoroethylene) or hollow stainless steel. The connecting rod 5 is fixed to the center position of the side of the spherical floating block 6, ensuring that when the floating block 6 is acted on by the buoyancy in the water, the force transmission path is always along the radial symmetry axis of the sphere, avoiding the floating block 6 from tilting or being stuck due to eccentric stress, making the opening and closing action of the ball valve 4 highly linearly related to the water level change. In addition, the low-resistance streamlined shape of the spherical floating block 6 can minimize the vortex generated when the water flows through, reducing the risk of false triggering of the valve rod 13 action by the local water level fluctuation around the floating block 6, especially suitable for construction environments such as rivers or drainage outlets where flow rate changes frequently. The cornerless design of the spherical surface can avoid the attachment of garbage (such as plastic bags, water plants), combined with the pre-filtering effect of the intercepting net 7, further reducing the probability of the floating block 6 being entangled and causing failure.

[0036] As a preferred example of the present application, the top inner wall of both sides of the frame is fixedly installed with a swivel ring 9, one of which is rotatably installed on the side of the floating block 6 away from the connecting rod 5 through a shaft (the shaft is fixedly connected with the floating block 6, and the swivel ring 9 is rotatably connected on the outside of the shaft), the inner side of the connecting rod 5 is fixedly installed with a connecting rod 8, the other end of the connecting rod 8 is fixedly connected with the floating block 6, and the other swivel ring 9 is rotatably installed on the outside of the connecting rod 8 through a bearing. The top of the drain pipe 3 is provided with a sliding rail 10, the sliding rail 10 is provided with a sliding block 11, the side of the sliding block 11 away from the gate 2 is provided with a rack 12, the outer periphery of the valve rod 13 is provided with a gear 14, the gear 14 is engaged with the rack 12, one end of the rack 12 is provided with a pulling piece 15, and the other end of the pulling piece 15 is installed on the outside of the swivel ring 9.

[0037] The floating block 6 rises and falls with the water level to drive the connecting rod and the valve rod 13 to rotate, open the valve core of the ball valve 4, and drive the gear 14 to rotate to drive the rack 12 to slide horizontally along the slide rail 10, pull the rotating ring 9 through the pulling piece 15, and rotate the intercepting net 7 to intercept the garbage on the water surface. The outer arc design can guide the garbage intercepted on the surface to other positions to avoid the accumulation of garbage on the net to cause excessive pressure on the net. The rotation of the intercepting net 7 completely depends on the natural hydraulic potential energy of the floating block 6, and the redundant kinetic energy of the opening and closing of the valve rod 13 is used to open and close the intercepting function through mechanical linkage, without the need to add a motor or a sensor, thereby reducing the system complexity and construction energy consumption cost.

[0038] As a preferred example of the present application, the outer side of the rotating ring 9 is provided with a winding groove 16, and the pulling piece 15 is a steel wire, one end of which is fixedly connected in the winding groove 16 (when the intercepting net 7 is in the initial state, the steel wire needs to be reserved a certain number of winding turns in the winding groove 16). The winding groove 16 can limit the steel wire on the outer periphery of the rotating ring 9 to avoid slipping of the steel wire during pulling and ensure uniform transmission of the pulling force in the tangential direction of the rotating ring 9.

[0039] As a preferred example of the present application, the support 1 is in a frame type, the bottom inner wall of which is provided with a limiting groove 17, and the two sides of the limiting groove 17 extend to the two inner walls of the support 1, respectively, to form a fully enclosed guide track, thereby ensuring that the gate 2 does not deviate laterally during lifting. The gate opening and closing mechanism includes a hydraulic cylinder 20, the driving end of which is rotatably connected to the top of the gate 2 through a rotating shaft, and the two sides of the gate 2 are movably arranged in the limiting groove 17. The rear side of the inside of the limiting groove 17 is provided with a first rubber layer 18, and the rear side of the gate 2 is provided with a second rubber layer 19. The first rubber layer 18 is soft rubber, and the second rubber layer 19 is hard rubber. The thickness of the gate 2 is slightly smaller than the width of the limiting groove 17.

[0040] The first rubber layer 18 (soft) deforms under pressure when the gate 2 is closed to fill the micro gap between the limiting groove 17 and the gate 2; the second rubber layer 19 (hard) serves as a support base to prevent the soft rubber from being compressed too much and failing. The two form a "soft-hard gradient sealing interface".

[0041] In addition, since the thickness of the gate 2 is slightly smaller than the width of the limiting groove 17 (such as the gap therebetween being between 0.5-1mm), the gate 2 is allowed to deflect slightly under water pressure impact, and the elastic deformation of the soft rubber layer compensates for the structural deformation, thereby avoiding the cracking of the sealing surface caused by rigid contact.

[0042] Compared with the prior art, the device sets the intercepting net 7 on the side of the floating block 6 away from the gate plate 2, when the floating block 6 is rotated and lifted by the water buoyancy, the ball valve 4 is opened, the water is discharged through the ball valve 4 and the drain pipe 3, at the same time, the intercepting net 7 can directly intercept the floating garbage such as branches and plastics carried in the water flow, effectively avoiding the garbage entering the inside of the drain pipe 3 to cause blockage, so as to ensure the continuous smoothness of the drain pipe 3 in the unattended condition; the linkage layout of the intercepting net 7 and the floating block 6 forms a double anti-blocking mechanism of "physical interception + water level triggering": the intercepting net 7 blocks the bulky sundries, the floating block 6 automatically opens and closes the ball valve 4 according to the water level change, effectively preventing the internal blockage risk caused by the too large instantaneous drainage capacity;

[0043] At the same time, when the water level rises to trigger the floating block 6 to drive the valve rod 13 to rotate and open the ball valve 4, the rotation of the valve rod 13 is converted into the horizontal sliding of the rack 12 by the gear 14 and the rack 12 transmission, the rotating ring 9 is driven by the pulling piece 15 to drive the intercepting net 7 to rotate (such as 0°-90° swing) around the center position of the floating block 6, and the interception of the garbage is completed.

[0044] The above is only the preferred specific implementation mode of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the application concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
