[0001] This utility model belongs to the field of water measuring weir technology, and more specifically, it relates to an integrated water measuring weir that is easy to clean. Background Technology

[0002] In water conservancy projects, hydrological monitoring, and wastewater treatment, weirs and flumes are frequently used for measuring and controlling water flow. During long-term use, to ensure the accuracy of measurement data, weirs and flumes often need to be kept clean to prevent blockage by debris. However, traditional devices lack convenient cleaning and sedimentation functions, leading to blockages caused by the continuous deposition of silt and debris in the water flow. Cleaning requires disassembling multiple components, resulting in low cleaning efficiency and increased measurement errors. This not only affects the reliability of flow data and leads to biased engineering decisions but also increases labor costs due to frequent maintenance, thus reducing the continuity of overall operations. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an integrated water measuring weir that is easy to clean, thus solving the technical problem that traditional devices in the prior art do not have convenient cleaning and sedimentation functions.

[0004] The purpose and function of this utility model, which provides an easy-to-clean integrated water measuring weir, are achieved through the following specific technical means: An easy-to-clean integrated water measuring weir includes a weir body, side wall partitions, and a sedimentation tank.

The sedimentation tank is located within the through grooves and has multiple sets of stainless steel grates. Multiple sets of PVC pipes are located at the bottom of the sedimentation tank, and a water stop valve is provided on one side of each PVC pipe. The weir body and the side wall partitions are connected by fixing bolts.

[0005] According to a preferred embodiment, multiple sets of placement slots are provided on multiple sets of mounting plates, and multiple sets of baffles are provided on one set of mounting plates, with the multiple sets of baffles arranged alternately from top to bottom along the mounting plates.

[0014] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0015] Example: For example Figures 1 to 2 As shown, this utility model provides an integrated water measuring weir that is easy to clean, including a weir body 11, a side wall partition 12, and a sedimentation tank 13. The side wall partition 12 is located inside the weir body 11, and a mounting base plate 14 is provided on the side wall partition 12. Through grooves are opened on the mounting base plate 14 and the side wall partition 12. Multiple sets of mounting plates 15 are provided on the side wall partition 12, one of which is equipped with a weir plate 16. The sedimentation tank 13 is located inside the through groove, and multiple sets of stainless steel grids 17 are provided inside the sedimentation tank 13. Multiple sets of PVC pipes 18 are provided at the bottom of the sedimentation tank 13, and a water stop valve 8 is provided on one side of each of the multiple sets of PVC pipes 18. The weir body 11 and the side wall partition 12 are connected by fixing bolts.

[0016] Specifically, the weir body 11 serves as the main structure of the water measuring weir, providing a channel for water flow measurement; the side wall partition 12 is connected to the weir body 11 by fixing bolts, enhancing the stability of the overall structure, and at the same time, it works with the mounting base plate 14 to form an internal support frame; the through channel provides installation space for the sedimentation tank box 13, allowing it to be placed stably and perform its sedimentation function; the stainless steel grating 17 can filter impurities such as mud and sand in the water flow inside the sedimentation tank box 13, preventing impurities from affecting subsequent measurements; the PVC pipe 18 works with the water stop valve 8 to drain the internal water before cleaning the sedimentation tank box 13, facilitating cleaning operations.

[0017] Multiple sets of mounting plates 15 are provided with multiple sets of placement slots. One set of mounting plates 15 is provided with multiple sets of baffles 19. The multiple sets of baffles 19 are arranged alternately from top to bottom along the mounting plate 15.

[0018] Specifically, the placement groove provides a location selection for the installation of components such as the weir plate 16 and the baffle plate 19, making it easy to adjust the installation height according to actual needs; the staggered baffle plates 19 can buffer and rectify the water flow, reduce water flow fluctuations, and make the water flow more smoothly towards the weir plate 16, thereby improving measurement accuracy.

[0019] The weir plate 16 is detachably connected to one of the mounting plates 15. The weir plate 16 is vertically set in the placement groove, and the weir plate 16 divides the weir groove body 11 into an upstream section and a downstream section.

[0020] Specifically, the detachable connection method facilitates the replacement and maintenance of the weir plate 16. Weir plates 16 with different specifications of notches can be replaced according to different measurement needs. The vertically set weir plate 16 can divide the weir channel body 11, so that the water in the upstream section flows through the weir plate 16 and enters the downstream section, forming a stable measurement environment.

[0021] The weir plate 16, the side wall partition 12, and the mounting base plate 14 are all made of stainless steel. The sedimentation tank box 13 is located on the side of the water inlet. The bottom of the weir body 11 is equipped with a water pipe protective shell 21.

[0022] Specifically, stainless steel is corrosion-resistant and has high strength, which can extend the service life of the weir plate 16, the side wall partition 12 and the mounting base plate 14, and adapt to long-term use in the water environment; the sedimentation tank box 13 is located on the side of the water inlet, which can perform sedimentation treatment before the water flows into the measurement area, reducing the interference of sediment on the measurement; the water pipe protective shell 21 can protect the PVC pipe 18 and prevent the pipe from being damaged by external factors.

[0023] One end of multiple sets of PVC pipes 18 is connected to the sedimentation tank box 13. The pipe body of multiple sets of PVC pipes 18 is sleeved in the water pipe protective shell 21, and the other end is inserted into the downstream section. The water stop valve 8 is located in the downstream section.

[0024] like Figures 3 to 4 Specifically, the PVC pipe 18 connects the sedimentation tank box 13 to the downstream section, providing a drainage channel for the water accumulated in the sedimentation tank box 13; the water pipe protective shell 21 wraps around the PVC pipe 18, further enhancing the protection of the pipe; the water stop valve 8 is located in the downstream section, making it convenient for operators to control the opening and closing of the PVC pipe 18, and to close it when drainage is not required, ensuring the normal operation of the measurement.

[0025] A triangular notch for water flow is provided on one side of the weir plate 16, with the angle of the triangular notch α ∈ (0°, 90°). A return sand plate 22 is provided on the mounting base plate 14. The return sand plate 22 is located on one side of the sedimentation tank box 13. The sedimentation tank box 13 is connected to the weir channel body 11 through multiple sets of ground cones.

[0026] Specifically, the triangular notch is the structure through which water flows through the weir plate 16. The angle range α∈(0°, 90°) allows the water to form a stable water level when it flows through, which is convenient for measuring the flow rate. The return sand plate 22 can guide the sediment deposited on the mounting base plate 14 to flow towards the sedimentation tank box 13, thereby improving the sediment collection efficiency. The ground cone connects the sedimentation tank box 13 and the weir body 11, which can not only ensure the installation stability of the sedimentation tank box 13, but also facilitate disassembly and cleaning, thereby improving the convenience of maintenance.

[0027] The specific usage and function of this embodiment are as follows: In use, the side wall partition 12 is first connected to the weir body 11 with fixing bolts to form an integrated structure. The water to be measured flows in from the upstream section of the weir body 11. At this time, the sedimentation tank box 13 on the side of the water inlet begins to function. The sediment in the water first passes through multiple sets of stainless steel grids 17 in the sedimentation tank box 13 for preliminary filtration, and larger particles of sediment are intercepted in the sedimentation tank box 13.

[0028] Next, the water continues to flow, passing through multiple sets of baffles 19 arranged in a staggered pattern on the mounting plate 15. The baffles 19 buffer and rectify the water flow, making it flow more smoothly towards the weir plate 16. Since the weir plate 16 is vertically installed in the placement trough and divides the weir trough body 11 into upstream and downstream sections, the water can only flow through the triangular notch on one side of the weir plate 16. By measuring the water level at the triangular notch, the water flow rate can be calculated according to relevant formulas.

[0029] During this process, some sediment will be deposited at the bottom of the weir body 11, while the return sand plate 22 located on one side of the sedimentation tank 13 will guide the deposited sediment towards the sedimentation tank 13, further promoting sediment collection. When it is necessary to clean the sediment in the sedimentation tank 13, since the sedimentation tank 13 is connected to the weir body 11 through multiple sets of ground cones, it can be easily removed for cleaning. At the same time, one end of multiple sets of PVC pipes 18 at the bottom of the sedimentation tank 13 is connected to the sedimentation tank 13, and the other end is inserted into the downstream section, with the pipe body sleeved in the water pipe protective shell 21. When it is necessary to drain the water in the sedimentation tank 13, the stop valve 8 located in the downstream section can be opened to allow the water to be discharged to the downstream section through the PVC pipes 18, realizing the drainage function of the sedimentation tank 13.

[0030] Its main functions are as follows: the side wall partition 12 and the weir body 11 are connected by fixing bolts to form an integrated structure, which improves the overall stability of the device; the stainless steel grid 17 in the sedimentation tank box 13 intercepts sediment, reducing the impact of sediment on subsequent measurements and equipment; the staggered arrangement of the baffles 19 makes the water flow smooth, and the triangular notch of the weir plate 16, utilizing the characteristic of a specific angle range α∈(0°, 90°), facilitates the measurement of the relationship between water level and flow rate; the return sand plate 22 guides sediment to move towards the sedimentation tank box 13, enhancing the sediment collection effect; the sedimentation tank box 13 is connected by a ground cone, which facilitates disassembly and cleaning, improving maintenance efficiency; the PVC pipe 18 and the stop valve 8 facilitate the drainage operation of the sedimentation tank box 13, ensuring the normal operation of the device. The overall structure is reasonably designed, which not only ensures the measurement accuracy of the measuring weir, but also facilitates daily cleaning and maintenance, extending the service life of the device.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
