Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a gate used in water conservancy projects. Background Art
[0002] At present, water conservancy refers to the development of hydropower resources or the prevention of floods, also known as water conservancy projects. Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects require the construction of dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways and other different types of hydraulic structures to achieve their goals. Flood control dams are one of the water conservancy projects used to intercept floods to prevent soil erosion and ecological damage downstream.
[0003] Among them, in order to facilitate the flood control dam to control the water volume, interception gates need to be set up on the flood control dam to play the role of intercepting and releasing the flow. The gates are widely used in water intake and water transfer, municipal construction, water supply and drainage, farmland irrigation and other projects.
[0004] After the gate is opened, not only the water in the upstream lake will continue to flow into the downstream lake, but also the floating objects and garbage on the surface of the upstream lake will flow into the downstream lake along with the water flow. For this reason, it is necessary to design a new technical solution to solve the problem. When the gate is opened to release water, the floating objects and garbage on the surface of the lake can be collected. Utility Model Content
[0005] The utility model aims to provide a gate for water conservancy projects, which solves the problems raised in the background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gate for a water conservancy project, comprising a gate frame, both sides of the gate frame are provided with limited sliding grooves, gates are slidably installed in two groups of the limited sliding grooves, a mounting seat is fixedly installed in the middle of one side of the gate, and a collecting mechanism is installed on the mounting seat;
[0007] The collecting mechanism includes expansion arms rotatably mounted on both sides of the mounting seat, fixings detachably mounted on the other ends of the two groups of expansion arms, a filter screen fixedly mounted between the two groups of fixings, positioning members fixedly mounted at both ends of one side of the gate, and steel wire ropes fixedly mounted on the two groups of positioning members, and the other ends of the two groups of steel wire ropes are respectively fixedly mounted on the two groups of fixing members.
[0008] As an optional solution of the technical solution of the present application, a threaded barrel is fixedly installed in the middle of the gate, and a threaded rod is connected to the inner thread of the threaded barrel, so that the gate can be lifted.
[0009] As an optional solution of the technical solution of the present application, limit grooves are provided at both ends of the middle part of the gate, and the two groups of limit grooves are arc grooves.
[0010] As an optional solution of the technical solution of the present application, limiting blocks are slidably installed in the two groups of limiting grooves, and the two groups of limiting blocks are respectively fixedly installed on the outer walls of the two groups of extension arms, so that the extension arms can be limited.
[0011] As an optional solution of the technical solution of the present application, first pulleys are fixedly installed at both ends of the top of the gate, and two groups of the first pulleys are movably connected to two groups of steel wire ropes respectively, so as to pull the steel wire ropes.
[0012] As an optional solution of the technical solution of the present application, second pulleys are fixedly installed at the four corners of the gate frame, and two corresponding groups of the second pulleys are movably connected to a group of steel wire ropes respectively, so as to pull the steel wire ropes.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] 1. According to the technical solution of the present application, as the gate continues to rise, the positioning pieces at both ends of one side of the gate will pull the bottom of the steel wire rope to continue to rise. When the bottoms of the two sets of steel wire ropes continue to rise, the first pulley and the second pulley will pull the other ends of the two sets of steel wire ropes to rise synchronously, and the two sets of extension arms will continue to rotate outward, so that the filter net between the two sets of extension arms will continue to expand as the gate rises, which can filter impurities and garbage floating in the water flow to prevent them from drifting to the downstream lake with the water flow.
[0015] 2. The technical solution of the present application is to slide limit blocks in two sets of limit grooves, and the two sets of limit blocks are respectively fixed to the outer walls of the two sets of extension arms. When the two sets of steel wire ropes pull the two sets of extension arms to rotate outward, the two sets of extension arms can be supported and limited by the limit blocks in the limit grooves, thereby further increasing the firmness and stability of the two sets of extension arms.

DETAILED DESCRIPTION
[0020] See also Figure 1-2 The utility model provides a technical solution: a gate for a water conservancy project, comprising a gate frame 1, both sides of the gate frame 1 are provided with limited sliding grooves 11, gates 12 are slidably installed in two sets of limited sliding grooves 11, a mounting seat 2 is fixedly installed in the middle of one side of the gate 12, and a collecting mechanism is installed on the mounting seat 2;
[0021] The collecting mechanism includes an extension arm 21 rotatably mounted on both sides of the mounting base 2, fixing members 22 detachably mounted on the other ends of the two sets of extension arms 21, a filter screen 23 fixedly mounted between the two sets of fixing members 22, positioning members 24 fixedly mounted at both ends of one side of the gate 12, and steel wire ropes 25 fixedly mounted on the two sets of positioning members 24, and the other ends of the two sets of steel wire ropes 25 are fixedly mounted on the two sets of fixing members 22 respectively.
[0022] In this technical solution, as the gate 12 continues to rise, the positioning pieces 24 located at both ends of one side of the gate 12 will pull the bottom of the steel wire rope 25 to continue to rise. When the bottoms of the two groups of steel wire ropes 25 continue to rise, the first pulley 32 and the second pulley 33 will pull the other ends of the two groups of steel wire ropes 25 to rise synchronously, and the two groups of expansion arms 21 will continue to rotate outward, so that the filter net 23 between the two groups of expansion arms 21 will continue to expand as the gate 12 rises, which can filter out impurities and garbage floating in the water flow and prevent them from drifting to the downstream lake with the water flow.
[0023] In some technical solutions, a threaded cylinder 13 is fixedly installed in the middle of the gate 12, and a threaded rod 14 is connected to the inner thread of the threaded cylinder 13, so that the gate 12 can be lifted. Limiting blocks 31 are slidably installed in the two sets of limiting grooves 3, and the two sets of limiting blocks 31 are respectively fixedly installed on the outer walls of the two sets of extension arms 21, so that the extension arms 21 can be limited.
[0024] In this technical solution, when the two sets of steel wire ropes 25 pull the two sets of extension arms 21 to rotate outward, the two sets of extension arms 21 can be supported and limited by the limit blocks 31 in the limit grooves 3, further increasing the firmness and stability of the two sets of extension arms 21.
[0025] In some technical solutions, first pulleys 32 are fixedly installed at both ends of the top of the gate 12, and the two groups of first pulleys 32 are movably connected to the two groups of steel ropes 25 respectively, so that the steel ropes 25 can be pulled, and second pulleys 33 are fixedly installed at the four corners of the gate frame 1, and the two corresponding groups of second pulleys 33 are movably connected to one group of steel ropes 25 respectively, so that the steel ropes 25 can be pulled.
[0026] In this technical solution, when the gate 12 continues to rise along the limiting slide groove 11, it will pull the positioning pieces 24 at the bottom of the two sets of steel wire ropes 25 to lift them. In conjunction with the first pulley 32 and the second pulley 33, the two sets of steel wire ropes 25 can be pulled in different directions to continuously lift the tops of the two sets of steel wire ropes 25.
[0027] In some technical solutions, a threaded barrel 13 is fixedly installed in the middle of the gate 12, and a threaded rod 14 is connected to the inner thread of the threaded barrel 13, so that the gate 12 can be lifted.
[0028] In this technical solution, when the threaded rod 14 is rotated, the threaded cylinder 13 threadably connected to the threaded rod 14 can lift the gate 12.
[0029] When a gate for a water conservancy project is used, it should be noted that the utility model is a gate for a water conservancy project, and each component is a universal standard part or a component known to technical personnel in this field, and its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.
[0030] When in use, the gate 12 installed inside the gate frame 1 can first be used to block the flow of water inside the river channel and control the direction and flow of the water flow. At the same time, after the threaded rod 14 in the threaded cylinder 13 is screwed, the gate 12 can be moved up and down in the limiting slide groove 11 to open the gate 12 in the gate frame 1. As the gate 12 continues to rise, the positioning members 24 at both ends of one side of the gate 12 will pull the bottom of the wire rope 25 to continue to rise. When the bottoms of the two groups of wire ropes 25 continue to rise, the first pulley 32 and the second pulley 33 will pull the other ends of the two groups of wire ropes 25 to rise synchronously, and the two groups of wire ropes 25 will be pulled up synchronously. The expansion arm 21 continuously rotates outward, so that the filter net 23 between the two groups of expansion arms 21 is continuously expanded as the gate 12 rises, which can filter the impurities and garbage floating in the water flow to prevent them from drifting to the downstream lake with the water flow. At the same time, the limiting blocks 31 are slidably installed in the two groups of limiting grooves 3, and the two groups of limiting blocks 31 are respectively fixed to the outer walls of the two groups of expansion arms 21. When the two groups of steel wire ropes 25 pull the two groups of expansion arms 21 to rotate outward, the limiting blocks 31 in the limiting grooves 3 can be used to support and limit the two groups of expansion arms 21, thereby further increasing the firmness and stability of the two groups of expansion arms 21.
