They are also called water projects. Only by building water conservancy projects can water flow be controlled, floods and waterlogging disasters can be prevented, and water volume can be regulated and distributed to meet the needs of people's lives and production for water resources. Gates are control facilities used to close and open drainage channels. They can be used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating objects.

[0003] Small rivers with gates not only have the function of flood discharge, but also have the function of viewing. However, due to the flow of water inside the river, there are usually many floating garbage such as mineral water bottles, plastic bags, leaves, etc., floating on the water surface and flowing downstream with the water flow. Especially in the river area inside the city, these garbage and debris will accumulate near the gate, which is very likely to cause damage to the environment. When people deal with floating garbage near the gate, they usually need to go into the water to collect and clean it, which increases the workload of workers and also increases the danger of workers' work.

DETAILED DESCRIPTION

[0028] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0029] Example 1

[0030] See also Figures 1 to 8 The embodiment of the present invention discloses a gate with a filtering function for a water conservancy project, which mainly includes a gate body 3, a support column 1, a lifting and lowering device, a gathering device and a conveying device 4. The gate body 3 is made of steel plate, which is easy to install and ensures structural strength. The gate body 3 is tilted inside the river channel, and support columns 1 cooperating with the gate body 3 are arranged on both sides. The outer side of the support column 1 is formed by welding steel plates and filled with concrete inside. There are two support columns 1, the cross section is trapezoidal, and the two support columns 1 are staggered front and back. The two opposite surfaces of the support column 1 are arranged in parallel. The gate body 3 is arranged between the two inclined surfaces, and the axis is perpendicular to the inclined surfaces of the two support columns 1, ensuring that the gate body 3 can fit tightly when closed and reduce water leakage. The conveying device 4 is arranged on one side of the rear support column 1, so that the collection effect is improved when the floating objects gather at the rear end, and the gate body 3 is arranged perpendicular to the end faces of the two support columns 1, ensuring that the gate can effectively intercept the water flow when closed, ensuring the control effect.

[0031] The side surface of the gate body 3 near the conveying device 4 is set as an inclined surface, and a gap is left between the inclined surface and the support column 1, so that the water flow can flow downstream from this gap. The water-facing surface is set at an obtuse angle to the direction of the water flow. When the gate body 3 has an intercepting effect, the water flow will produce a flow effect of a certain angle on the water-facing surface of the gate body 3, so that floating objects in the water flow can gather more smoothly to the conveying device 4, thereby improving the collection effect.

[0032] A lifting and lowering device is arranged on the back water surface of the gate body 3, which is used to control the lifting and lowering of the gate body 3. The lifting and lowering device includes a mounting platform 2 arranged at the rear of the gate body 3. The mounting platform 2 is cast with concrete and has a certain height to reduce the immersion time of the upper device in the water. A connecting seat 202 is arranged on the upper surface of the mounting platform 2. A hydraulic cylinder 201 is hingedly arranged at the rear of the connecting seat 202. The output end of the hydraulic cylinder 201 is hingedly connected to the back water surface of the gate body 3. A support frame 203 is arranged in front of the connecting seat 202 and is connected to the gate body 3. Through the extension and retraction of the hydraulic cylinder 201 and the support of the support frame 203, the lifting and lowering of the gate body 3 and the inclination angle relative to the water surface can be controlled. According to the actual water flow conditions, the collection of floating objects inside the river channel is controlled. Compared with the lifting gate in the prior art, the space occupied in the river channel is reduced, and there is no need to set an operating table on the top of the support column 1. It can be set as a centralized control station for remote control. The operation is simple and the collection effect is obvious.

[0033] The connecting seat 202 includes a fixed base, a fixed box 2021 is provided at the front end of the base, a rotating shaft 2031 is provided inside the fixed box 2021, the top of the support frame 203 is hinged to the rotating shaft 2031, so that the support frame 203 can swing with the rotating shaft 2031 as the center, and the tail of the support frame 203 is fixed to the back of the gate body 3. The support frame 203 cooperates with the hydraulic cylinder 201 so that the gate body 3 can be stably set between the two support columns 1. When the hydraulic cylinder 201 is extended, the gate body 3 is closed, and when the hydraulic cylinder 201 is retracted, the gate body 3 is opened, thereby ensuring the interception effect of the water flow and improving the control effect.

[0034] Rollers 2032 are arranged at both ends of the rotating shaft 2031, and the rollers 2032 are slidably connected with the guide grooves arranged inside the fixed box 2021, so as to reduce the friction resistance of the rotating shaft 2031 during the rotation process and improve the flexibility of rotation. A telescopic column is also hinged on the side of the rotating shaft 2031, and the other end of the telescopic column is fixedly arranged. One structure of the telescopic column includes a sleeve 2022 hinged on the rotating shaft 2031, and a main rod 2023 is slidably arranged inside the sleeve 2022, and one end of the main rod 2023 is fixedly arranged. A large pressure spring 2024 is wound around the outer side of the main rod 2023, so that the rotating shaft 2031 has a forward pushing pressure, and the gate body 3 has a space for front and rear adjustment, which greatly improves the control effect.

[0035] The back surface of the gate body 3 is also provided with a plugging device for controlling the gap between the gate body 3 and the support column 1. The plugging device includes a telescopic frame arranged on the back surface of the gate body 3. A plug 206 is arranged at the output end of the telescopic frame. A guide groove 101 for guiding the plug 206 is arranged on the side of the support column 1 near the plug 206. The guide groove 101 is an arc-shaped groove, and the tail depth of the guide groove 101 is greater than the front depth, so that when the plug 206 enters the gap between the support column 1 and the gate body 3, the plug 206 The gap between the two can be filled, and the front end surface of the plug 206 is set as an arc surface, which is convenient for turning along the guide groove 101 and better entering the gap; wherein the telescopic frame includes a second oil cylinder 204 arranged on the back water surface of the gate plate, the second oil cylinder 204 is arranged horizontally along the gate plate body 3, and a scissor frame 205 is hinged at the output end of the second oil cylinder 204, and the end of the scissor frame 205 is hinged with the plug 206, and the second oil cylinder 204 causes the plug 206 to move along the back water surface of the gate plate body 3 through the scissor frame 205. The end of the scissor frame 205 is hinged to the plug 206 through the rotating shaft 2031. The back of the plug 206 is set as a curved surface with a large curvature. The front end of the side of the plug 206 abutting against the gate body 3 is set as a plane, and the rear is provided with a curved surface with a small curvature. When in use, the plug 206 moves toward the support column 1 and is guided by the guide groove 101. The front part of the plug 206 turns to enter the gap. As the second oil cylinder 204 extends, the gate body 3 is gradually clamped, and the interception is completed. When the opening When the gate is opened, the second oil cylinder 204 contracts, and the small arc surface inside the plug block 206 slides along the edge of the gate body 3, providing an operating space for recovering the plug block 206. A rubber pad is fixed on the side of the plug block 206 to ensure the sealing effect. The use of the plug block 206 and the scissor frame 205 greatly improves the control effect, and when the plug block 206 is not moving, the water flow can flow out along the gap between the support column 1 and the gate body 3, so that the water flow in front of the gate body 3 flows, and the floating objects gather to the conveying device 4 for easy collection.

[0036] When the gate body 3 needs to intercept, the plug 206 is inserted into the guide groove 101 of the support column 1 under the action of the telescopic frame, filling the gap between the gate body 3 and the support column 1 to prevent water from leaking from the gap. In order to ensure the interception effect, a small angle slope is set on the other side of the gate body 3, and a rubber pad is fixed on the slope. When the plug 206 enters the guide groove 101, it will squeeze the gate body 3 to the right, so that both sides of the gate body 3 can be sealed, and the interception effect of the gate body is not reduced, thereby improving controllability. The water-facing surface of the gate body 3 is provided with a gathering device for collecting floating objects, which can effectively gather floating objects together, wherein the gathering device includes a connecting rod 303 arranged at the front end of the gate body 3, the connecting rod 303 is arranged along the width direction of the gate body 3, a plurality of vertical rods 301 are hinged on the connecting rod 303, the upper part of the vertical rod 301 is hollow, the center of gravity of the vertical rod 301 is set at one end near the connecting rod 303, a plurality of collecting wheels 302 are sleeved on the outer side of the vertical rod 301, the collecting wheel 302 is made of lightweight material, so that the upper part of the collecting wheel 302 protrudes above the water surface, and the lower part of the collecting wheel 302 is below the water surface, and the collecting wheels 302 on the plurality of vertical rods 301 are arranged on the outer side of the vertical rod 301. The wheels 302 are arranged in parallel. When in use, the water flows along the inclined surface of the gate body 3 to the gap between the support column 1, thereby driving the collecting wheel 302 to rotate on the vertical rod 301, and then pushing the floating objects in the water flow to the conveying device 4. When the water flow is large or small, the depth of the water flow is controlled by controlling the rotation angle of the gate body 3, and under the action of the buoyancy of the water flow, the vertical rod 301 can drive the collecting wheel 302 to remain vertical as much as possible, and a limit pin is provided at the hinge of the vertical rod 301 and the connecting rod 303, so that the maximum angle between the vertical rod 301 and the gate body 3 is 60 degrees, so that when the gate is opened, the gathering device can be recovered close to the gate body 3, thereby improving the use effect.

[0037] The output end of the gathering device is provided with a conveying device 4 for conveying the lifted floating objects. The conveying device 4 can adopt a belt conveyor or a screw conveyor, etc., to convey the gathered floating objects to a collection vehicle or a processing station for centralized collection and processing, thereby realizing the effective cleaning and collection of floating objects in the river channel, reducing the occupied space, and can be remotely controlled, which greatly improves the cleaning efficiency and safety.
