Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to a water measuring weir that can be cleaned. Background Art
[0002] A water measuring weir refers to an overflow weir installed in a channel or a water trough for measuring the flow rate of water. The most commonly used one is a thin-walled weir with a special notch. According to the shape of the notch, the thin-walled water measuring weir can be divided into several types such as triangular weir, rectangular weir, trapezoidal weir, etc. In reality, for example, the seepage flow rate behind an earth-rock dam is relatively large. Usually, a cut-off wall is set behind the dam and a water measuring weir is used for observation. The weir type of the water measuring weir is generally a rectangular weir or a trapezoidal weir.
[0003] In actual observation, the reliability of the measured seepage flow value is affected by various factors. First of all, the catchment area of the field water measuring weir is relatively large, and the surrounding plants are lush. There are often animals and plants falling into the weir trough. It is easy to breed insect eggs on the ditch wall, and silt accumulates at the bottom of the ditch, raising the water head above the weir, resulting in distorted measured values. Moreover, the traffic in the catchment area of some field water measuring weirs is inconvenient, and the depth and slope of the water channels are different. Some water channels are relatively deep and difficult to clean. Secondly, the ordinary cleaning device will inevitably cause water flow fluctuations in the weir trough after installation, resulting in certain deviations in the water gauge readings.
[0004] Therefore, a water measuring weir that can be cleaned is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a water measuring weir that can be cleaned to solve the problems raised in the above background art.
[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:
[0007] A water measuring weir that can be cleaned includes a track device, a transmission bracket, a movable bracket and a storage box. The track device is fixedly installed on the edge of the water channel. One end of the rotating part of the track device is fixedly installed with a handle. The rear side wall of the movable part of the track device is fixedly installed with a transmission bracket, and the transmission bracket is perpendicular to the rotating part of the track device. The surface of the transmission bracket is provided with a movable bracket. The bottom end of the movable bracket is hinged and installed with a storage box through a pin shaft. Two groups of hooks are arranged at the inner bottom of the storage box. A spring is hung on the surface of the movable bracket. A fixed block is installed at the inner bottom of the track device.

[0026] Such as Figures 1 to 4As shown in the figure, a cleanable weir includes a track device 1, a transmission bracket 2, a movable bracket 3, and a storage box 4. The track device 1 is fixedly installed on the side of the water channel. One end of the rotating part of the track device 1 is fixedly installed with a handle 5. The rear side wall of the movable part of the track device 1 is fixedly installed with a transmission bracket 2, and the transmission bracket 2 is perpendicular to the rotating part of the track device 1. The surface of the transmission bracket 2 is provided with a movable bracket 3. The bottom end of the movable bracket 3 is hinged and installed with a storage box 4 through a pin shaft. Two groups of hooks 8 are arranged at the inner bottom of the storage box 4. A spring 9 is hung on the surface of the movable bracket 3. A fixed block 6 is installed at the inner bottom of the track device 1. A baffle 7 is hinged and installed on the inner wall of the storage box 4 through a pin shaft; specifically, the two ends of the spring 9 are respectively hung on the hooks 8 at one end of the movable bracket 3 and the storage box 4. At this time, the storage box 4 forms a certain angle with the movable bracket 3 under the action of the spring. The locking of the movable part of the movable bracket 3 is released, and the movable part of the movable bracket 3 together with the storage box 4 is slowly lowered so that one end of the storage box 4 contacts the bottom of the ditch. After adjusting the angle, the movable part of the movable bracket 3 is locked. The handle 5 is manually rotated, so that through the track device 1, the storage box 4 and the movable bracket 3 move slowly along the water channel under the action of the transmission bracket 2, continuously shoveling up the silt and sundries at the bottom of the water. The baffle 7 is fixed by the fixed block 6. At this time, the storage box 4 starts to hold the silt, and the silt only goes in and does not come out. The insect eggs along the ditch wall are also removed. When the transmission bracket 2 moves to the end of the track device 1, the locking of the movable part of the movable bracket 3 is released, the storage box 4 is lifted, and the baffle 7 is rotated in the opposite direction of the fixed block 6 to dump the garbage. When cleaning in the reverse direction, the spring 9 buckle is hung on the other hook 8 at the bottom of the storage box 4, and the previous operation is repeated to repeatedly clean the water channel to further consolidate the cleaning effect. After the cleaning is completed, the movable bracket 3 and the storage box 4 are both suspended in the water channel under the action of the transmission bracket 2, and will not affect the reading accuracy of the weir.
[0027] As Figure 1 , Figure 2 , Figure 3 shown in the figure, the track device 1 includes a side frame 101. A threaded rod 102 is rotatably inserted into the inside of the side frame 101. One end of the threaded rod 102 is fixedly installed with a handle 5. A threaded sleeve 103 is sleeved on the surface of the threaded rod 102. Opposite surfaces of the two groups of side frames 101 are fixedly installed with guide rods 104. The rear side wall of the threaded sleeve 103 is fixedly installed with a transmission bracket 2; specifically, by manually rotating the handle 5, the handle 5 drives the threaded rod 102 to rotate. Through the meshing of the threaded rod 102 and the threaded sleeve 103, the threaded sleeve 103 and the transmission bracket 2 are horizontally moved, and then the storage box 4 is driven to move along the water channel through the transmission bracket 2 and the movable bracket 3.
[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the movable support 3 includes a movable rod 301. Two groups of through holes are provided on the top surface of the transmission support 2, and the movable rod 301 is inserted and installed in both groups of through holes. The bottom end of the movable rod 301 is hinged and installed with a storage box 4 through a pin shaft. A fastening screw 303 for fixing the movable rod 301 is threadedly inserted into the right side wall of the transmission support 2. Specifically, when hanging the spring 9, one end of the spring 9 is hung on the surface of the cross bar 302. By rotating the fastening screw 303, one end of the fastening screw 303 is separated from the surface of the movable rod 301, thereby unlocking the movable rod 301, and then the storage box 4 can be vertically lifted. By rotating the fastening screw 303, one end of the fastening screw 303 is closely attached to the surface of the movable rod 301, thereby locking the movable rod 301.
[0029] As Figure 2 、 Figure 4 shown, the pin shaft for the hinge connection between the baffle 7 and the storage box 4 is located above the baffle 7, and the inner walls of the baffle 7 and the storage box 4 are in a fitting arrangement. Specifically, by the inner walls of the baffle 7 and the storage box 4 being in a fitting arrangement, the sludge and garbage are cleaned.
[0030] As Figure 1 、 Figure 2 、 Figure 3 shown, a hole is provided on the surface of the transmission support 2 close to the threaded sleeve 103, and this hole corresponds to the guide rod 104. The transmission support 2 is movably inserted through this hole and the surface of the guide rod 104. Specifically, by the hole provided on the surface of the transmission support 2 being inserted into the guide rod 104, the lateral movement of the transmission support 2 is guided and limited.
[0031] As Figure 1 、 Figure 2 、 Figure 3 shown, the fastening screw 303 corresponds to the through hole on the surface of the transmission support 2, and when fixing the movable rod 301, one end of the fastening screw 303 is closely attached to the surface of the movable rod 301. Specifically, by the fastening screw 303 on the surface of the transmission support 2 corresponding to the through hole, the movable rod 301 is locked by the fastening screw 303.
[0032] In summary: Hang the two ends of the spring 9 on the movable bracket 3 and the hook 8 at one end of the storage box 4 respectively. At this time, the storage box 4 forms a certain angle with the movable bracket 3 under the action of the spring. Release the lock of the movable part of the movable bracket 3, and slowly lower the movable part of the movable bracket 3 together with the storage box 4 so that one end of the storage box 4 contacts the bottom of the ditch. After adjusting the angle, lock the movable part of the movable bracket 3. Manually rotate the handle 5 so that through the track device 1, the storage box 4 and the movable bracket 3 move slowly along the ditch under the action of the transmission bracket 2, continuously shoveling up the silt and sundries at the bottom of the water. The baffle 7 is fixed by the fixing block 6. At this time, the storage box 4 starts to hold the silt, and the silt only goes in and does not come out. The insect eggs along the ditch wall are also removed. When the transmission bracket 2 moves to the end of the track device 1, release the lock of the movable part of the movable bracket 3, lift up the storage box 4, and rotate the baffle 7 in the reverse direction of the fixing block 6 to dump the garbage. When cleaning in the reverse direction, hang the spring 9 buckle on the other hook 8 at the bottom of the storage box 4, repeat the previous operation, and clean the ditch repeatedly to further consolidate the cleaning effect. After the cleaning is completed, the movable bracket 3 and the storage box 4 are both suspended in the ditch under the action of the transmission bracket 2, and will not affect the water measuring weir reading accuracy.
