[0022] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0024] Example 1, referring to Figures 1 to 3 This embodiment provides an installation structure, including:

[0025] Support assembly 1 includes a mounting base 11, a receiving member 12 disposed at the lower part of the mounting base 11, and a retaining plate 13 disposed outside the mounting base 11. A plug 14 is disposed at the lower end of the mounting base 11, and a receiving cavity 15 is disposed in the receiving member 12 opposite to the plug 14. The receiving cavity 15 is open at the upper end, and the outer diameter of the plug 14 is slightly larger than the inner diameter of the receiving cavity 15.

[0026] The clamping assembly 2 includes at least two clamps 21 fixed to the mounting base 11.

[0027] The installation structure of this application is more suitable for the installation of equipment in narrow locations (where it is inconvenient for operators to enter), such as the installation of the water measuring weir 4 inside the weir trough 3. With this installation structure, operators can disassemble and assemble the water measuring weir 4 without entering the interior of the weir trough 3, which greatly improves the portability of the installation. At the same time, the installation structure does not rely on bolts or other fixing parts when disassembling and assembling, further improving portability.

[0028] Specifically, the mounting base 11 is a cuboid, and the clamping plates 13 are L-shaped. Two clamping plates 13 are fixed symmetrically to the inner wall of the weir trough 3 as a set, and at least one set of clamping plates 13 is arranged vertically, as shown in the attached figure. A space is formed between the clamping plates 13 and the inner wall of the weir trough 3 for the mounting base 11 to penetrate vertically. The receiving member 12 is fixed to the bottom of the weir trough 3 and is located directly below the mounting base 11. As the mounting base 11 moves downward, the plug 14 at the lower end of the mounting base 11 is inserted into the receiving cavity 15 of the receiving member 12. Because the plug 14 is tightly inserted into the receiving cavity 15 of the receiving member 12, the plug 14 is inserted into the receiving cavity 15 of the receiving member 12. Within the cavity 15, the movement of the plug 14 is restricted, which in turn restricts the movement of the mounting base 11. The clamping plate 13 further limits the mounting base 11, restricting its lateral movement and improving the overall stability of the mounting base 11 after installation. Since the mounting base 11 is vertically set with the measuring weir 4, it can also play a certain role in preventing it from rising due to the overall gravity of the measuring weir 4 and the mounting base 11. To enhance this effect, the mounting base 11 is made of heavy stainless steel, and counterweights can also be embedded in the mounting base 11.

[0029] To reduce the lateral sway of the mounting base 11, the distance between the two left and right clamping plates 13 in the same group is the same as the width of the mounting base 11, and the distance between the inner wall of the outer end of the clamping plate 13 and the inner wall of the weir trough 3 is the same as the thickness of the mounting base 11.

[0030] During the initial fabrication of the weir trough 3, the receiving component 12 can be fixed at the bottom of the weir trough 3, and the clamping plate 13 can be fixed inside the weir trough 3. This avoids the problem of inconvenient installation of the receiving component 12 and the clamping plate 13 after the weir trough 3 is used. Based on this, the specific installation process of the water measuring weir gauge 4 is as follows: the water measuring weir gauge 4 is passed through each clamp 21 and the clamp 21 is tightened. Then, the mounting base 11 is slowly inserted between the clamping plate 13 and the inner wall of the weir trough 3 and slowly moved downwards. As the mounting base 11 moves downwards, the plug 14 gradually extends into the receiving cavity 15, and the water measuring weir gauge 4 gradually approaches the weir trough 3. The water measuring weir 4 is installed until it contacts the bottom of the weir trough 3 and stops descending. Of course, the clamping position of the water measuring weir 4 should ensure that when the water measuring weir 4 contacts the bottom of the weir trough 3, the plug 14 extends into the receiving cavity 15 and the bottom of the plug 14 does not contact the bottom of the receiving cavity 15 or just contacts the bottom of the receiving cavity 15. This can be achieved through simple measurement or the operating experience of the operator. When the water measuring weir 4 needs to be removed, the operator can use manpower or lifting tools (such as hoisting equipment) to slowly pull the installation base 11 upward.

[0031] Furthermore, the support assembly 1 also includes a connecting pipe 16 disposed on the lower end side wall of the receiving member 12, the connecting pipe 16 being connected to the receiving cavity 15, and a solenoid valve 17 being disposed on the connecting pipe 16.

[0032] The solenoid valve 17 and the connecting pipe 16 are designed to further enhance the stability of the plug 14 after it enters the receiving cavity 15 by utilizing negative pressure. Specifically, the connecting pipe 16 connects the inside of the weir trough 3 and the receiving cavity 15. When the plug 14 enters the receiving cavity 15, the solenoid valve 17 is in the open state. As the plug 14 enters, the fluid (water or air) in the receiving cavity 15 is discharged from the connecting pipe 16. When the bottom of the measuring weir 4 contacts the bottom of the weir trough 3, the plug 14 stops descending and then the solenoid valve 17 is closed. At this time, the portion of the receiving cavity 15 at the bottom of the plug 14 is a sealed space. When the plug 14 is impacted or other external forces have an upward tendency, negative pressure will be formed in this sealed space to hinder the upward movement of the plug 14, further enhancing the overall stability after installation. When the measuring weir 4 needs to be removed, the solenoid valve 17 is opened to avoid hindering the upward pulling out of the plug 14.

[0033] To improve the sealing between the plug body 14 and the inner wall of the receiving cavity 15, both the plug body 14 and the receiving cavity 15 are cylindrical, and the plug body 14 is a rubber part with a certain degree of elasticity. The outer diameter of the plug body 14 is slightly larger than the aperture of the receiving cavity 15. Of course, it is necessary to ensure that the plug body 14 can be inserted into the receiving cavity 15.

[0034] Furthermore, the receiving cavity 15 extends through the lower end of the receiving member 12.

[0035] The lower end of the receiving cavity 15 passes through the lower end of the receiving member 12, so that the connecting pipe 16 can be arranged on the lower side wall of the receiving cavity 15. When the solenoid valve 17 and the connecting pipe 16 are installed, the connecting pipe 16 and the solenoid valve 17 can contact the bottom of the weir trough 3, so that the bottom of the weir trough 3 supports the connecting pipe 16 and the solenoid valve 17, preventing the connecting pipe 16 and the solenoid valve 17 from being suspended, and ensuring stability and working stability.

[0036] Example 2, refer to Figures 1 to 3 In order for the plug 14 to be smoothly inserted into the receiving cavity 15, the lower end of the plug 14 is a downward curved hemispherical shape. Of course, the lower end of the plug 14 can also be a cone shape that gradually decreases in size downwards.

[0037] Furthermore, to facilitate operation by workers, the support assembly 1 also includes a handle 18 located at the top of the mounting base 11. Additionally, a lifting ring can be provided at the upper end of the support assembly 1 to allow for the lifting of the mounting base 11 by a hoisting device if it is difficult to pull it out.

[0038] Furthermore, the clamping assembly 2 also includes a mounting plate 22 fixed to the clamp 21. The mounting plate 22 is fixed to the mounting base 11 by bolts. The projections of the clamping plate 13 and the mounting plate 22 in the vertical direction do not overlap.

[0039] The projections of the clamping plate 13 and the mounting plate 22 in the vertical direction do not overlap, that is, the clamping plate 13 does not obstruct the mounting plate 22 from moving up and down with the mounting base 11. Specifically, there is a certain distance between the clamping plates 13 on both sides, which is greater than the width of the mounting plate 22, that is, the mounting plate 22 is located between the clamping plates 13 on both sides.

[0040] Example 3, referring to Figure 4 A seepage monitoring device for a hydropower station, including an installation structure, and further comprising,

[0041] The weir trough 3, the clamping plate 13 is fixed on the inner wall of the weir trough 3, the mounting base 11 is vertically inserted between the clamping plate 13 and the weir trough 3, the receiving component 12 is fixed at the bottom of the weir trough 3, and the receiving component is located directly below the mounting base 11, and the plug 14 extends into the receiving cavity 15.

[0042] The water measuring weir 4 is placed vertically inside the weir trough 3, with the lower end of the water measuring weir 4 in contact with the bottom of the weir trough 3, and the clamp 21 is held in place outside the water measuring weir 4.

[0043] The hydropower station seepage monitoring device of this application, by adopting the above-mentioned installation structure, greatly improves the portability of the water measuring weir 4 for installation and disassembly.

[0044] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
