Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy facilities, in particular to a water measuring weir behind an earth-rock dam which is easy to clean. Background Art

[0002] A water measuring weir refers to an overflow weir installed in a channel or trough to measure water flow. The most commonly used one is a thin-walled weir with a special notch. According to the shape of the notch, thin-walled water measuring weirs can be divided into several types, such as triangular weir, rectangular weir, and trapezoidal weir.

[0003] In practice, due to the high seepage volume behind earth-rockfill dams, a cutoff wall is typically installed behind the dam, and observations are made using a measuring weir, typically a rectangular or trapezoidal weir. In actual observations, the reliability of seepage volume measurements is affected by a variety of factors. First, measuring weirs behind earth-rockfill dams are typically located outdoors, with a large catchment area and lush vegetation. Plants and animals often fall into the weir trough, which easily accumulates floating debris on the weir plate, increasing the water head above the weir and causing distorted measurements. Furthermore, the catchment area behind earth-rockfill dams is generally inaccessible, and the ditches are relatively deep, making them difficult to clean. Second, the fluctuating flow within the weir trough causes a certain degree of deviation in the water gauge readings.

[0004] For this purpose, a water measuring weir behind an earth-rock dam which is easy to clean is proposed. Utility Model Content

[0005] The purpose of the present invention is to solve the problems mentioned in the above background technology and to provide a water measuring weir behind an earth-rock dam that is easy to clean.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] Furthermore, the trash-blocking assembly includes a trash rack, a bracket is fixedly connected to the bottom of the front side of the trash rack, and a leakage net is arranged above the bracket.

[0009] Furthermore, the number of the leakage nets is two, and the two leakage nets are symmetrically arranged on the left and right sides of the bracket.

[0010] Furthermore, the lifting control assembly includes a fixed pulley, and the fixed pulley is rotatably connected to the inner wall of the fixed tube, the surface of the fixed pulley is slidably connected to a traction rope, the bottom end of the traction rope is fixedly connected to a limiting block, and the front side of the limiting block is fixedly connected to the bracket by a bolt, the front and back sides of the fixed tube are penetrated by limiting grooves, and the inner wall of the limiting groove is slidably connected to the surface of the limiting block.

Therefore, they cannot be understood as a limitation on the present invention.

[0024] like Figures 1 to 4As shown, a water-measuring weir behind an earth-rockfill dam, designed for easy cleaning, includes a fixed pipe 1 fixedly mounted within the dam. A debris-trapping assembly 3 is positioned on the upstream side of the fixed pipe 1. A lifting control assembly 2 is mounted within the fixed pipe 1 to control the vertical movement of the debris-trapping assembly 3. A rotational limiter assembly 4 is positioned on the surface of the debris-trapping assembly 3 to collect debris from the surface of the debris-trapping assembly 3. More specifically, the debris-trapping assembly 3 can intercept foreign objects such as branches, leaves, and animal carcasses drifting down from upstream, as well as branches and small debris dropped from the surrounding jungle. After a period of operation, a user on shore can control the lifting control assembly 2 to pull the debris-trapping assembly 3 upward, lifting it out of the water. The user can then control the rotational limiter assembly 4 to fold and gather the debris toward the center of the debris-trapping assembly 3, allowing the user to clean the debris from the surface of the debris-trapping assembly 3.

[0025] Trash rack assembly 3 includes a trash rack 301, with a bracket 302 fixedly connected to the front bottom of trash rack 301. A filter net 303 is installed above bracket 302. It should be noted that trash rack 301 can intercept foreign matter such as branches, leaves, and animal carcasses drifting down from upstream, while filter net 303 can collect branches and small debris that fall from the surrounding jungle in front.

[0026] There are two leakage nets 303, and the two leakage nets 303 are symmetrically arranged on the left and right sides of the bracket 302. More specifically, by symmetrically arranging the two leakage nets 303, they can be folded in the center under the action of the rotation limit assembly 4, thereby gathering debris and facilitating subsequent cleaning.

[0027] The lifting control assembly 2 includes a fixed pulley 201, and the fixed pulley 201 is rotatably connected to the inner wall of the fixed tube 1. The surface of the fixed pulley 201 is slidably connected to the traction rope 202. The bottom end of the traction rope 202 is fixedly connected to the limiting block 203, and the front side of the limiting block 203 is fixedly connected to the bracket 302 by a bolt. The front and back sides of the fixed tube 1 are penetrated by limiting grooves 204, and the inner wall of the limiting groove 204 is slidably connected to the surface of the limiting block 203. It should be noted that the user grasps the free end of the traction rope 202 on the shore, pulls the traction rope 202 to slide along the surface of the fixed pulley 201, and then pulls the limit block 203, so that the limit block 203 slides along the inner wall of the limit groove 204, and the pollution-blocking component 3 can be controlled to move upward and out of the water surface, thereby cleaning the debris on the surface of the pollution-blocking component 3. During the cleaning process, the end of the traction rope 202 can be tied to a fixed object on the shore. Similarly, when the pollution-blocking component 3 is cleaned, the traction rope 202 is released, and under the action of gravity, the pollution-blocking component 3 will re-enter the water.

[0028] The rotation limit assembly 4 includes a rotating sleeve 401, and the rotating sleeve 401 is rotatably connected to the bracket 302, and the end of the rotating sleeve 401 is fixedly connected to the trash rack 301, the front end of the bracket 302 is fixedly connected to a fixed column 402, the end of the fixed column 402 is fixedly connected to a limit frame 403, an arc-shaped slide groove 404 is provided on the back side of the limit frame 403, the inner wall of the arc-shaped slide groove 404 is slidably connected to a support rod 405, the front end of the leakage net 303 is fixedly connected to a slide rail 406, and the inner wall of the slide rail 406 is slidably connected to the support rod 405. More specifically, when the net 303 emerges from the water surface, the net 303 is rotated to drive the rotating sleeve 401 to rotate around the surface of the bracket 302. During the rotation of the net 303, the two ends of the support rod 405 slide along the inner wall of the arc-shaped slide groove 404 and the inner wall of the slide rail 406 respectively. The slide rail 406, the support rod 405 and the arc-shaped slide groove 404 cooperate with each other to limit the rotation trajectory of the net 303, so that the net 303 remains stable. As the net 303 gradually tilts, the effect of gravity will cause the debris on the surface of the net 303 to continuously slide down and gather in the middle, thereby facilitating the subsequent cleaning of the debris.

[0029] The trash rack 301 is a grid structure, and the drain net 303 is a mesh structure. It should be noted that the provision of the trash rack 301 with a grid structure can stabilize the water flow while intercepting debris, thereby ensuring the accuracy of the water weir measurement value.

[0030] In summary: the pollution-blocking component 3 can be used to intercept foreign objects such as branches, leaves or animal carcasses drifting down from upstream, and can also collect branches and small debris dropped from the surrounding jungle. After running for a period of time, the user can control the operation of the lifting control component 2 on the shore, pull the pollution-blocking component 3 to move upward, so that the pollution-blocking component 3 is out of the water surface, and then control the pollution-blocking component 3 to fold and gather by rotating the limit component 4, so that the debris gathers in the middle of the pollution-blocking component 3. Then the user can uniformly clean the debris on the surface of the pollution-blocking component 3, which realizes the effect of automatically collecting debris in the water flow during use. After collection, it can be lifted for cleaning, making the cleaning and maintenance process more convenient, avoiding the failure of the water measuring weir due to sediment accumulation, and also stabilizing the water flow to ensure accurate readings.
