Description

Technical Field

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

[0002] In water conservancy projects (such as South-to-North Water Diversion Project channels, reservoir dams, and irrigation canals), water level measurement is a core component ensuring the safe operation, scientific scheduling, and efficient management of the project. Water gauges, as key equipment for directly reading water level data, are constantly exposed to water, humid air, and complex geological environments, making them susceptible to corrosion, impacts, and other damage that can lead to blurred scales or structural damage, necessitating regular maintenance and replacement. Traditional water gauges are often directly fixed to the lining panels, wing walls, or dam surfaces using expansion bolts. Replacement requires removing the old bolts and re-drilling holes, which not only repeatedly damages the engineering structure but may also affect measurement accuracy due to drilling position deviations. Furthermore, replacement work often involves water-related, high-altitude, or underwater environments, and to avoid disrupting normal water flow, water cannot be shut off during the operation, resulting in complex procedures, long processing times, and high safety risks for maintenance personnel. Therefore, those skilled in the art have provided a water level measurement device for water conservancy projects to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide a water level measuring device for water conservancy projects to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A water level measuring device for hydraulic engineering, comprising:

[0006] The track is provided with an installation component and a hook is connected to the track via a fixing component. The track has a first connecting groove and a through groove on one side. The track is provided with a sealing gasket layer.

[0007] The first water gauge and the second water gauge are connected by a locking mechanism, and both the first water gauge and the second water gauge are connected in the first connecting groove. A cover is connected to the track by a rotating component, and a through hole is opened on the first water gauge.

[0008] Preferably, the mounting assembly includes a plurality of mounting blocks, which are fixedly connected to the track, and the mounting blocks are provided with mounting threaded holes.

[0009] Preferably, the fixing component includes a placement block and a buckle. The placement block is installed on the track by bolts. The placement block has a placement groove. One end of the hook is engaged in the placement groove. The buckle is fixedly installed on the track, and the end of the hook away from the placement block is engaged in the buckle.

[0010] Preferably, a plurality of rotating beads are rotatably connected within the track, and the plurality of rotating beads are slidably connected to the first water gauge and the second water gauge.

[0011] Preferably, the sealing gasket layer is provided with a plurality of raised rings, and the plurality of raised rings are in contact with and connected to the first water gauge and the second water gauge.

[0012] Preferably, the locking mechanism includes a connecting block, a return spring, a locking block, a first sealing ring, and a second sealing ring. The connecting block is fixedly connected to the second water gauge. The first water gauge has a second connecting groove, and the connecting block is locked in the second connecting groove. The connecting block has an installation groove. One end of the return spring is installed in the installation groove, and the other end of the return spring is connected to the locking block. The first water gauge has a locking groove, and the locking block passes through the installation groove and is locked in the locking groove. The first sealing ring is connected between the first water gauge and the second water gauge, and the second sealing ring is connected to the outside of the locking block.

[0013] Preferably, the rotating assembly includes a drive motor, a rotating rod, a first rotating block, and two second rotating blocks. The two second rotating blocks are fixedly mounted on the track, and the first rotating block is fixedly mounted on the cover. The first rotating block is rotatably connected between the two second rotating blocks via the rotating rod.

[0014] Preferably, a controller is installed on the track, a handle is provided on the hook, a control button is installed on the handle, a battery is installed on the cover, and the controller is electrically connected to the control button, the drive motor, and the battery.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the design of the track, mounting components, and fixing components, changes the traditional method of directly fixing the water level gauge with expansion bolts. When maintenance or replacement of the water level gauge is required, there is no need to re-drill holes. The replacement operation can be easily completed by simply sliding the mounting components on the track and connecting and disassembling the fixing components. This not only avoids repeated damage to the lining panel or wing wall, protecting the integrity of the engineering structure, but also saves the manpower, material resources, and time consumed by re-drilling, significantly improving the efficiency of water level gauge maintenance and replacement.

[0017] 2. The structural design of this utility model effectively reduces the operational risks and complexity of water level gauge replacement. Traditional water level gauge replacement often involves dangerous operations such as those at heights, near edges, near water, or underwater. This device, however, uses a track-mounted installation method, allowing the disassembly and installation of the water level gauge primarily to be carried out within the track area, reducing the exposure time and operational difficulty for workers in hazardous environments. Simultaneously, it eliminates the need for channel water shut-off, ensuring the normal water conveyance function of the channel and avoiding the impact on project scheduling caused by water outages. This allows maintenance personnel to complete the work in a safer environment, significantly reducing the operational risks. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figures 1-7 This utility model provides a technical solution:

[0028] A water level measuring device for hydraulic engineering, comprising:

[0029] The track 1 is equipped with an installation assembly, which includes several mounting blocks 10. The mounting blocks 10 are fixedly connected to the track 1, and the mounting blocks 10 have mounting threaded holes 11. The track 1 is connected to a hook 2 via a fixing assembly, which includes a placement block 12 and a buckle 13. The placement block 12 is installed on the track 1 by bolts, and the placement block 12 has a placement groove 14. One end of the hook 2 is engaged in the placement groove 14. The buckle 13 is fixedly installed on the track 1, and the end of the hook 2 away from the placement block 12 is engaged in the buckle 13. The track 1 has a first connecting groove 3, and a through groove 4 is opened on one side of the first connecting groove 3. The track 1 is equipped with a sealing gasket 5, and the sealing gasket 5 has several protruding rings 16. The several protruding rings 16 are in contact with and connected to the first water gauge 6 and the second water gauge 7.

[0030] The first water gauge 6 and the second water gauge 7 are rotatably connected to a number of rotating beads 15 in the track 1, and the number of rotating beads 15 are slidably connected to the first water gauge 6 and the second water gauge 7. The first water gauge 6 and the second water gauge 7 are connected by a locking mechanism, and both the first water gauge 6 and the second water gauge 7 are connected in the first connecting groove 3. A cover 8 is connected to the track 1 by a rotating component, and a through hole 9 is opened on the first water gauge 6.

[0031] When removing hook 2, the worker holds hook 2 with handle 31, disengages the end of hook 2 away from placement block 12 from buckle 13, and then removes one end of hook 2 from placement slot 14 of placement block 12. Placement block 12 is detachably connected to track 1 with bolts. Its installation position can be flexibly adjusted by loosening the bolts and moving placement block 12 along the length of track 1. This design allows placement block 12 to be positioned optimally according to the workspace, worker habits, and hook retrieval path requirements, ensuring ergonomic storage and retrieval of hook 2, reducing redundant operations, and improving tool retrieval efficiency. Next, after opening cover 8 and pulling out the first water gauge 6 and second water gauge 7, hook 2 is aligned with the through hole 9 on the first water gauge 6, ensuring a secure connection. The worker pulls hook 2 using handle 31, and under the pulling force of hook 2, the first water gauge 6 and second water gauge 7 slide along the rotating ball 15 within track 1. Due to the rolling action of the ball bearing 15, the friction between the water gauge and the track 1 is reduced, allowing the water gauge to be smoothly pulled out of the track 1. During the extraction process, the first water gauge 6 and the second water gauge 7 are connected by a locking mechanism and are extracted together.

[0032] When installing a new water gauge, push the connected new water gauge along the ball bearing 15 inside the track 1 until it reaches the predetermined position. During this process, the raised ring 16 on the sealing gasket 5 contacts the water gauge, ensuring a seal between the water gauge and the track 1.

[0033] Specifically, the locking mechanism includes a connecting block 17, a return spring 18, a locking block 19, a first sealing ring 20, and a second sealing ring 21. The connecting block 17 is fixedly connected to the second water gauge 7. The first water gauge 6 has a second connecting groove 22, and the connecting block 17 is locked in the second connecting groove 22. The connecting block 17 has an installation groove 23. One end of the return spring 18 is installed in the installation groove 23, and the other end of the return spring 18 is connected to the locking block 19. The first water gauge 6 has a locking groove 24, and the locking block 19 passes through the installation groove 23 and is locked in the locking groove 24. The first sealing ring 20 is connected between the first water gauge 6 and the second water gauge 7, and the second sealing ring 21 is connected to the outside of the locking block 19.

[0034] When separating the first water gauge 6 and the second water gauge 7, press the locking block 19 to compress the return spring 18 and disengage it from the locking groove 24, thus separating the first water gauge 6 and the second water gauge 7. After replacing with a new water gauge, reverse the operation to connect the new first water gauge 6 and the second water gauge 7 together through the locking mechanism. It should be noted that the first water gauge 6 and the second water gauge 7 are only examples to illustrate the locking mechanism; in actual applications, the number of segments can be flexibly expanded according to measurement needs.

[0035] The return spring 18 is made of stainless steel and has a multi-layer anti-corrosion coating (such as a polytetrafluoroethylene coating) on ​​its surface, which can effectively resist water corrosion. Meanwhile, the second sealing ring 21 tightly wraps around the gap between the locking block 19 and the mounting groove 23, significantly reducing water seepage into the mounting groove 23 and minimizing direct contact between the spring and water. Compared to elastic materials such as rubber, metal springs are less prone to aging and deformation in long-term underwater environments, and the sealing design ensures the long-term reliable operation of the locking mechanism.

[0036] The first sealing ring 20 is installed between the first water gauge 6 and the second water gauge 7, effectively preventing water from entering from the connection between the two water gauges, reducing the risk of corrosion or damage to the water gauge connection components due to water seepage, or affecting the overall stability of the water gauge structure. The second sealing ring 21 is connected to the outside of the locking block 19, and its main function is to reduce the entry of water into the mounting groove 23, reduce the corrosion of components such as the return spring 18 by water, and keep the locking mechanism in good working condition.

[0037] The rotating assembly includes a drive motor 25, a rotating rod 26, a first rotating block 27, and two second rotating blocks 28. The two second rotating blocks 28 are fixedly mounted on the track 1, and the first rotating block 27 is fixedly mounted on the cover 8. The first rotating block 27 is rotatably connected between the two second rotating blocks 28 through the rotating rod 26. The drive motor 25 is mounted on the track 1 through a fixing block 29, and the output end of the drive motor 25 is connected to the extension end of the rotating rod 26 that passes through the second rotating block 28.

[0038] When opening the cover 8, the operator presses the control button 32 on the handle 31. Upon receiving the signal, the controller 30 starts the drive motor 25. The output of the drive motor 25 drives the rotating rod 26 to rotate. Through the cooperation of the first rotating block 27 and the second rotating block 28, the rotating rod 26 causes the cover 8 to rotate and open around the rotating rod 26, exposing one end of the first water gauge 6 inside the track 1. When closing the cover 8, the operator can press the control button 32 on the handle 31. The controller 30 then reverses the drive motor 25, causing the cover 8 to close.

[0039] The procedure for removing the water level gauge is as follows:

[0040] Open cover 8: Press the control button 32 on the handle 31. The controller 30 drives the motor 25 to rotate the rotating rod 26. The rotating rod 26, through the cooperation of the first rotating block 27 and the second rotating block 28, causes the cover 8 to flip upward around the rotating rod 26, fully exposing the opening at the end of the track 1.

[0041] Connecting hook 2 to water gauge: Insert one end of hook 2 into the through hole 9 of the first water gauge 6, and control the other end with the handle 31 held by the staff.

[0042] Pulling out the water gauge: The operator pulls the hook 2 through the handle 31. Under the pulling force, the first water gauge 6 drives the second water gauge 7 (and other splicing sections) to slide along the inside of the track 1. Since the ball bearing 15 inside the track 1 is in contact with the surface of the water gauge, the sliding friction is converted into rolling friction, which greatly reduces the resistance and allows the water gauge to be smoothly pulled out from the track 1.

[0043] Separation and replacement: After pulling out, press the locking block 19 to separate the water gauge sections. Replace the damaged sections and reassemble them. Then, push the water gauge back into the track 1 in the reverse process. Finally, close the cover 8 to complete the operation.

[0044] In the above embodiment, a controller 30 is installed on the track 1, a handle 31 is provided on the hook 2, a control button 32 is installed on the handle 31, a battery 33 is installed on the cover 8, and the controller 30 is electrically connected to the control button 32, the drive motor 25 and the battery 33.

[0045] It should be noted that the specific models and specifications of the controller 30, control button 32, drive motor 25 and battery 33 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
