Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water level measuring device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They develop, utilize, protect and manage water resources through various facilities such as dams, dikes, sluices, pumping stations and canals.

[0003] CN222544787U discloses a water level measuring device for water conservancy projects. First, a base plate is installed on a platform, with the reservoir surface in front of the platform. A float floats on the water surface. As the water level rises, the buoyancy of the float pushes a hollow tube upwards, causing a guide bar to move within a waist hole. The pointers on both sides of the guide bar then move along the scale lines, indicating the water level. Additionally, as the guide bar moves within the waist hole, a slider integrally connected to the guide bar moves within the housing, ensuring smooth movement of the guide bar and preventing jamming. The L-shaped scale plate indicates the safe water level.

[0004] This water level measuring device for water conservancy projects has a simple structure, reasonable design, and novel and unique concept. However, since the scale plate, pointer, and hollow tube are prone to damage during long-term use and it is inconvenient to replace them individually, which increases the subsequent maintenance cost, we propose a water level measuring device for water conservancy projects. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a device for measuring water level in water conservancy projects.

[0006] This utility model is achieved using the following technical solution: a water level measuring device for water conservancy projects, comprising a fixed plate, a positioning groove at the left end of the fixed plate, a positioning plate inserted into the inner wall of the positioning groove, a scale plate fixedly connected to the left end of the positioning plate, a limit component at the top of the fixed plate, a threaded rod threadedly connected to the inner wall of the fixed plate, a through groove at the middle of the scale plate, an extension rod inside the through groove, a sleeve threadedly connected to the surface of the extension rod, a pointer fixedly connected to the surface of the sleeve, an installation sleeve fixedly connected to the bottom of the sleeve, a hollow tube threadedly connected to the inner wall of the installation sleeve, a float hinged to the bottom of the hollow tube, and a scale plate fixedly connected to the bottom of the fixed plate.

[0007] With the above technical solution, since the hollow tube is threadedly connected to the mounting sleeve, when the hollow tube needs to be replaced, it can be disassembled by rotating the hollow tube, which is convenient for subsequent replacement of the damaged hollow tube. When the pointer needs to be replaced, it can be disassembled by rotating the sleeve, which is convenient for replacement of the pointer. The modular design makes it easy to replace individual components in the future, reducing subsequent maintenance costs. The scale plate is used to indicate the safe water level.

[0008] As a further improvement to the above solution, the limiting component includes a fixing frame, the inner wall of which has a limiting groove, and a roller is provided inside the limiting groove.

[0009] The above technical solution limits the roller by using a limiting groove. At the same time, the friction between the roller and the inner wall of the limiting groove is reduced when the roller moves, avoiding jamming and ensuring stability during use.

[0010] As a further improvement to the above solution, a fixed rod is rotatably connected to the inner wall of the roller, and a fixed block is fixedly connected to the surface of the fixed rod.

[0011] The above technical solution uses a fixing rod to support the two rollers.

[0012] As a further improvement to the above solution, the bottom of the fixing frame is fixedly connected to the top of the fixing plate, and the surface of the roller is slidably connected to the inner wall of the limiting groove.

[0013] As a further improvement to the above solution, the number of rollers is set to two, and the two rollers are symmetrically distributed with the fixed plate as the center.

[0014] The above technical solution, through two symmetrically arranged rollers, ensures balance during use and avoids the possible deviation caused by a single roller.

[0015] As a further improvement to the above solution, the left end of the fixing block is fixedly connected to the right end of the extension rod.

[0016] With the above technical solution, since the extension rod is fixedly connected to the fixed block, when the extension rod moves up or down, the fixed block will move, causing the roller to move.

[0017] As a further improvement to the above solution, the lower end of the threaded rod passes through the fixing plate and is threadedly connected to the inner wall of the positioning plate.

[0018] The above technical solution uses a threaded rod to install and fix the positioning plate, which facilitates subsequent disassembly and improves maintenance convenience. During installation, the positioning plate is inserted into the positioning groove, which limits the position of the positioning plate and facilitates subsequent installation.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model incorporates a positioning plate, a threaded rod, an extension rod, a sleeve, and an installation sleeve. Specifically, the entire assembly can be disassembled by rotating the hollow tube, facilitating subsequent replacement of any damaged hollow tubes. When the pointer needs replacement, it can be disassembled by rotating the sleeve, allowing for easy pointer replacement. When the scale plate needs replacement, the threaded rod is removed, freeing the positioning plate from its fixation, thus allowing for easy removal and replacement. This improves the convenience of subsequent maintenance. During scale plate installation, the positioning plate is inserted into the positioning groove for positioning, and then fixed in place by the threaded rod. The operation is simple and convenient, enhancing installation ease.

[0021] This utility model uses a limiting component. Specifically, when the water level rises, the buoyancy of the float will push the hollow tube upward, and at the same time, the fixed block will move upward. The roller slides on the inner wall of the limiting groove, ensuring the accuracy of the movement. The roller reduces the friction when in contact with the inner wall of the limiting groove, thus avoiding jamming. Attached Figure Description

A float ball 13 is hinged to the bottom of the hollow tube 12, and a scale plate 14 is fixedly connected to the bottom of the fixing plate 1. When the hollow tube 12 needs to be replaced, it can be disassembled by rotating the hollow tube 12 since the top of the hollow tube 12 is threaded to the inner wall of the mounting sleeve 11, which facilitates the replacement of the damaged hollow tube 12. When the pointer 10 needs to be replaced, it can be disassembled by rotating the sleeve 9, which facilitates the replacement of the pointer 10. When the scale plate 4 needs to be replaced, the scale plate 4 can be disassembled and removed for replacement by disassembling the threaded rod 6 and removing the fixation of the positioning plate 3, which improves the convenience of subsequent maintenance.

[0031] The limiting component 5 includes a fixing frame 501, and a limiting groove 502 is formed on the inner wall of the fixing frame 501. A roller 503 is provided inside the limiting groove 502. When the water level rises, the buoyancy of the float 13 will push the hollow tube 12 to move upward, and at the same time the fixing block 505 will move upward. The roller 503 slides on the inner wall of the limiting groove 502, ensuring the accuracy of movement. The roller 503 reduces the friction when in contact with the inner wall of the limiting groove 502, avoiding jamming.

[0032] A fixing rod 504 is rotatably connected to the inner wall of the roller 503, and a fixing block 505 is fixedly connected to the surface of the fixing rod 504.

[0033] The bottom of the fixed frame 501 is fixedly connected to the top of the fixed plate 1, and the surface of the roller 503 is slidably connected to the inner wall of the limiting groove 502.

[0034] There are two rollers 503, which are symmetrically distributed around the fixed plate 1. The two symmetrically arranged rollers 503 reduce friction and ensure stability during movement.

[0035] The left end of the fixing block 505 is fixedly connected to the right end of the extension rod 8.

[0036] The lower end of the threaded rod 6 passes through the fixing plate 1 and is threadedly connected to the inner wall of the positioning plate 3. When installing the scale plate 4, the positioning plate 3 is inserted into the positioning groove 2 and positioned by the positioning groove 2. Then, the positioning plate 3 is installed and fixed by the threaded rod 6. The operation is simple and convenient, which improves the ease of installation.

[0037] The implementation principle of a water level measuring device for water conservancy projects in this embodiment is as follows: During use, a fixing plate 1 is installed on a platform, with the reservoir water surface at the front. A float 13 is attached to the water surface. When the water level rises, the buoyancy of the float 13 pushes the hollow tube 12 upwards, simultaneously moving the fixing block 505 upwards. The roller 503 slides on the inner wall of the limiting groove 502, ensuring accuracy during movement. The roller 503 reduces friction when in contact with the inner wall of the limiting groove 502, preventing jamming. Simultaneously, the sleeve 9 and pointer 10 move to indicate the water level. When the hollow tube 12 needs to be replaced, the top of the hollow tube 12 is attached to the mounting plate. The inner wall threaded connection of sleeve 11 can be disassembled by rotating hollow tube 12, facilitating the replacement of damaged hollow tube 12. When the pointer 10 needs to be replaced, it can be disassembled by rotating sleeve 9, facilitating the replacement of pointer 10. When the scale plate 4 needs to be replaced, the fixing of positioning plate 3 can be removed by disassembling threaded rod 6, thus removing the scale plate 4 for replacement, improving the convenience of subsequent maintenance. When installing the scale plate 4, positioning plate 3 is inserted into the positioning groove 2, and positioning plate 3 is positioned by positioning groove 2. Then, positioning plate 3 is installed and fixed by threaded rod 6. The operation is simple and convenient, improving the convenience of installation.
