Embodiment 1

[0020] Such as Figure 1-Figure 3 As shown, the cleaning device suitable for the sediment in the weir flume of the water measuring weir provided in this embodiment is integrally arranged on the side facing the water of the weir plate 103 of the water measuring weir, and is mainly composed of a bottom plate 201, a baffle plate 203 and a wing plate 202. Composition, the baffle plate 203 is attached and arranged parallel to the weir plate 103 of the water measuring weir, the bottom plate 201 and the wing plate 202 are respectively connected to the lower side and both sides of the baffle plate 203 away from the weir plate 103 of the water measuring The inner wall of the weir, weir and flume 101 is attached to the accommodation chamber, so that the cleaning device 200 can be assembled with the water measuring weir and weir flume 101 and the water measuring weir and weir plate 103 without gaps, avoiding the leakage of minerals such as calcium and magnesium compounds in the water flow...

Embodiment 2

[0024] This embodiment provides a cleaning device suitable for the sediment in the weir flume of the water measuring weir. Snap-fit ​​construction.

[0025] Considering the convenience of cleaning up the sludge, see figure 1 and image 3 , the lifting ring 204 can be installed on the cleaning device 200, and the lifting ring 204 is fixed on the baffle plate 203 through the connecting rod 205. Here, the lifting ring 204 and the connecting rod 205 can also be replaced by handles, handles, and handrails in other structural forms. , or tow ropes, tow chains, and the like. As a way to further optimize the operability, the lifting rings 204 are arranged symmetrically on the left and right sides, and the two lifting rings 204 are respectively installed on the upper parts of the two ends of the baffle plate 203 close to the inner wall of the water measuring weir weir groove 101. It can be the top of the baffle 203 or any other position, of course it can also be the top of the wing ...

Embodiment 3

[0027] On the basis of the above two preferred embodiments, in order to prevent mineral deposits on both sides of the water measuring weir weir flume 101 and ensure that the device can be taken out smoothly, the height of the wing plate 202 and the water measuring weir weir flume 101 can also be kept Consistent and topped with a chamfered edge.

[0028] In order to ensure the smooth flow of the water flow, it is advisable that the outlet of the bottom plate 201 is provided with a smooth chamfer.

[0029] In terms of materials, the bottom plate 201, baffle plate 203 and wing plate 202 in each preferred embodiment are all preferably made of stainless steel, which is relatively reasonably priced, can ensure mineral adhesion, and also has a certain anti-corrosion effect.

[0030] For the water outlet 104 cross-sectional shape of the water measuring weir weir plate 103 described in the embodiment can be various, for example triangular, trapezoidal or rectangular etc., in figure 2...

Abstract

According to the cleaning device suitable for the sediment in the measuring weir groove, the measuring weir comprises the measuring weir groove and a measuring weir plate, and the cleaning device is installed in the measuring weir groove in a sliding connection mode and located on one side of the upstream face of the measuring weir plate; the cleaning device is mainly composed of a bottom plate, a baffle and a wing plate, the baffle is attached to and parallel to the flow measuring weir plate, the highest point of the baffle is not higher than the lowest point of a water outlet in the flow measuring weir plate, and the bottom plate and the wing plate are connected to the lower portion of the side, away from the flow measuring weir plate, of the baffle and the two side portions of the baffle respectively to define a containing cavity attached to the inner wall of a flow measuring weir groove. According to the invention, deposits can be cleaned economically and conveniently, and the measurement precision and the service life of monitoring equipment are prevented from being affected.

Description

technical field [0001] The invention relates to a desilting device, in particular to a cleaning device suitable for deposits in weirs and grooves of water measuring weirs, and belongs to the technical field of water conservancy engineering. Background technique [0002] As known, the water measuring weir refers to the overflow weir arranged at the end of the dam drainage channel to measure the flow of water. It is used to monitor the seepage of dams, especially in the monitoring of seepage of earth-rock dams, which plays a key role. However, most of the rivers in our country contain high calcium and magnesium ion minerals, which are easy to deposit near the water measuring weir. After a long period of time, silting will occur near the weir plate and weir flume of the water measuring weir. [0003] For many years, the cleaning of calcium and magnesium compounds in the water measuring weir has always been a heart problem for professional operators, and even affects the normal...
