Description

Technical Field

[0001] This utility model relates to the field of water measuring weir technology, specifically an integrated water measuring weir. Background Technology

[0002] Dam seepage monitoring involves monitoring the seepage field within the dam body and is a crucial means of ensuring the safe operation of the dam. Through monitoring, the patterns of seepage changes can be understood, and potential problems in the dam body and foundation can be predicted based on the trends in seepage flow. Monitoring is typically based on two indicators: leakage rate and seepage flow rate. Low leakage rate indicates the dam is operating normally; high leakage rate indicates an abnormality. Seepage flow rate and seepage velocity are two important indicators reflecting seepage conditions, and their trends directly reflect changes in the dam's seepage flow. Therefore, monitoring seepage flow rate can serve as a basis for evaluating the effectiveness of dam seepage control.

[0003] Currently, the main monitoring technology involves setting up a flow measurement weir downstream of the dam. Existing flow measurement methods generally use concrete-cast diversion channels and triangular weirs, which involve many steps such as formwork erection and concrete pouring. This method is time-consuming, labor-intensive, and has low construction efficiency and high construction costs. Therefore, it is necessary to design and modify the integrated flow measurement weir to effectively prevent the problems of low construction efficiency and inconvenience in use.

It solves the problem that the current main technical measures for monitoring flow measurement involve setting up a water measurement weir downstream of the dam. Existing water measurement weirs generally use concrete pouring of diversion channels and setting up triangular weirs for flow measurement. In the implementation process, it involves many procedures such as formwork erection and concrete pouring. This method has many procedures, is time-consuming and labor-intensive, has low construction efficiency, and has high construction costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, an integrated water measuring weir includes a flow guide frame 1. The inner wall of the flow guide frame 1 is provided with a limiting groove 2. A weir plate 3 is slidably connected inside the limiting groove 2. Limiting blocks 4 are fixedly connected to both sides of the inner wall of the flow guide frame 1. Bolts 5 are threadedly connected inside the limiting blocks 4. The bolts 5 are threadedly connected to the weir plate 3. The back of the limiting blocks 4 is in contact with the front of the weir plate 3. An extension frame 6 is in contact with the front of the flow guide frame 1. A docking frame 7 is fixedly connected to both the front of the extension frame 6 and the front of the flow guide frame 1. A docking groove is provided on both the back of the extension frame 6 and the back of the flow guide frame 1. The docking frame 7 is inserted into the docking groove. A first L-shaped mounting frame 8 and a second L-shaped mounting frame 9 are fixedly connected to both sides of the flow guide frame 1 and both sides of the extension frame 6, respectively. The first L-shaped mounting frame 8 and the second L-shaped mounting frame 9 are in contact with each other and are fixedly connected by screws.

[0022] refer to Figure 1 , Figure 3 and Figure 5The bottom of the flow guide 1 and the bottom of the extension frame 6 are respectively fixedly connected to a first support plate 10 and a second support plate 11. The first support plate 10 and the second support plate 11 are in contact. The surfaces of the first support plate 10 and the second support plate 11 are both fixedly connected to a reinforcing frame 12. The reinforcing frame 12 is fixedly connected to the flow guide 1 and the extension frame 6 respectively.

[0023] As a technical optimization of this utility model, the first support plate 10 and the second support plate 11 can support the flow guide frame 1 and the extension frame 6. By setting the reinforcing frame 12, the stability of the flow guide frame 1 and the extension frame 6 can be improved by utilizing the stability of the triangle, and the side walls of the flow guide frame 1 and the extension frame 6 can be prevented from bending to the sides.

[0024] refer to Figures 1 to 4 Both sides of the flow guide 1 are fixedly connected to the fixing blocks 13. The top of the fixing blocks 13 is provided with a slot. The inside of the slot is slidably connected to the connecting bracket 14. The top of the connecting bracket 14 is fixedly connected to the handle.

[0025] As a technical optimization of this utility model, by setting up the fixing block 13, the slot, the connecting frame 14 and the handle, the operator can insert the connecting frame 14 into the slot at the top of the fixing block 13, so as to prevent the side walls of the flow guide frame 1 and the extension frame 6 from bending to the sides, thereby improving the structural strength of the flow guide frame 1 and the extension frame 6.

[0026] refer to Figure 1 and Figure 4 Both sides of the top of the weir plate 3 are fixedly connected to support rods 15, and small balls 16 are fixedly connected to the surface of the support rods 15.

[0027] As a technical optimization of this utility model, by setting up the support rod 15 and the small ball 16, the operator can hold the small ball 16 and then pull the support rod 15 upward, thereby driving the weir plate 3 to move upward, which makes it easier for the operator to take out the weir plate 3.

[0028] refer to Figures 1 to 5 The surface of bolt 5 is coated with anti-rust paint, and the surfaces of guide frame 1, weir plate 3 and extension frame 6 are all provided with electroplated anti-rust layer.

[0029] As a technical optimization of this utility model, the bolt 5 is prevented from rusting by spraying anti-rust paint on its surface, and the flow guide frame 1, weir plate 3 and extension frame 6 are prevented from rusting by setting an electroplated anti-rust layer on their surfaces.

[0030] refer to Figure 1 and Figure 4 The downstream edge of the weir plate 3 has a 45° chamfer.

[0031] As a technical optimization of this utility model, by setting a 45-degree chamfer on the surface edge of the weir plate 3 near the downstream side, the water can flow smoothly when it comes into contact with the weir opening.

[0032] The working principle and usage process of this utility model: When using and selecting and installing the water measuring weir plate, the length of the upstream and downstream channel sections is a key factor, as it directly affects the stability of the water flow and the accuracy of the measurement. In this device, the back of the weir plate 3 is the upstream section, and the front of the weir plate 3 is the downstream section. This device can connect the extension frame 6 to the back or front of the guide frame 1 according to the actual situation, thereby adjusting the length of the upstream and downstream sections of the weir plate 3. For example, when the operator needs to connect a certain length of extension frame 6 to the downstream section of the weir plate 3, the operator aligns the docking groove on the back of the customized extension frame 6 with the docking frame 7 on the front of the guide frame 1, so that the docking frame 7 is inserted into the docking groove. At this time, the guide frame 1 and the extension frame 6 are in close contact. At this time, the first L-shaped mounting frame 8 on the surface of the guide frame 1 and the second L-shaped mounting frame 9 on the surface of the extension frame 6 are in contact. Then, the first L-shaped mounting frame 8 and the second L-shaped mounting frame 9 are connected by screws, thereby completing the installation of the extension frame 6. Thus, the length of the upstream and downstream channel sections of the weir plate 3 is controlled according to the specifications, so that the downstream outflow is smooth and free outflow is guaranteed.

[0033] When the operator needs to replace the weir plate 3, the operator can remove the bolt 5 to release the locking between the limiting block 4 and the weir plate 3. Then the operator can pull the weir plate 3 upward to separate the weir plate 3 from the limiting groove 2, thereby completing the disassembly of the weir plate 3.
