Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and more specifically, to a cable fastening device for water conservancy and hydropower construction. Background Technology

[0002] Water conservancy and hydropower engineering is a comprehensive engineering field involving the development, utilization and management of water resources. It covers many aspects and has a profound impact on social development and energy supply. In water conservancy and hydropower engineering, cable installation is an essential and critical link. To ensure the reliability of cables in long-term operation, advanced cable fastening devices are also required.

[0003] A search revealed a Chinese patent application with patent number CN213212951U, which discloses a cable fixing and protection device for water conservancy and hydropower projects. The device includes a base plate, four evenly distributed first springs fixedly connected to the upper end of the base plate, a support plate fixedly connected to the upper end of the four first springs, a through hole drilled in the upper end of the support plate, a fixing block disposed in the through hole, and a third spring fixedly connected to the front, back, left, and right ends of the fixing block. The four third springs are respectively fixedly connected to the front, back, left, and right inner walls of the through hole. A lower clamping plate is fixedly connected to the upper end of the fixing block, and an upper clamping plate is disposed on the upper part of the lower clamping plate.

[0004] In the aforementioned patent, the cable is held by hand, placed inside the lower clamping plate, and the upper clamping plate is held by hand. The lower and upper clamping plates are fixed together by the interaction of two mounting screws and two mounting nuts. Then, depending on the size of the cable, the fastening screws are turned, and the cable is further secured by the interaction of the fastening screws and the arc-shaped washer. In windy weather, the elasticity of four third springs dampens the lower clamping plate in all four directions (front, back, left, and right). The interaction of four first and second springs weakens the longitudinal vibration force of the lower clamping plate. This protects the cable from damage or even breakage due to excessive vibration in windy weather. Ultimately, multiple shock absorption methods significantly reduce the vibration force on the cable. This achieves the effect of protecting the cable from breakage, thereby ensuring the normal construction of water conservancy and hydropower projects. However, the following shortcomings still exist in the use of this method: 1. In the complex and long-term operating environment of water conservancy and hydropower projects, the springs continuously bear the alternating stress caused by cable vibration, which is prone to fatigue and weakens elasticity. If a spring malfunctions, due to its relatively concealed installation location and its connection with other components, disassembling and replacing the spring is difficult and requires a lot of time and manpower, which may affect the continuous operation of the project; 2. The structure of fixing the cable by the lower clamping plate, upper clamping plate, fastening screws, and arc-shaped pads has limitations in adapting to cables of different diameters and shapes, making it difficult to provide stable fixation and protection.

[0005] Therefore, there is an urgent need for a cable fastening device for water conservancy and hydropower construction to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a cable fastening device for water conservancy and hydropower construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A cable fastening device for water conservancy and hydropower construction includes a support plate, the outer wall of which is connected to a base plate and a fixing block via a detachable component, and further includes:

[0009] A guide clamping assembly includes a fixed sleeve fixedly connected to the top wall of a fixed block, a fixed plate fixedly connected to the inner wall of the fixed sleeve, a uniformly distributed sliding groove on the outer wall of the fixed plate, a slider slidably connected to the inner wall of the sliding groove, a drive rod fixedly connected to the outer wall of the slider, an auxiliary rod fixedly connected to the outer wall of the slider, and a clamping plate fixedly connected to the end of the auxiliary rod away from the slider.

[0010] A drive assembly is disposed on the inner wall of the fixed sleeve, and the drive assembly cooperates with the guide clamping assembly.

[0011] As a preferred technical solution of this application, the driving assembly includes a driving disk rotatably connected to the inner wall of the fixed sleeve. The outer wall of the driving disk is provided with uniformly distributed driving grooves, and the inner wall of the driving groove abuts against the outer wall of the driving rod. A bolt is fixedly connected to the outer wall of the driving disk, and a nut is threadedly connected to the outer wall of the bolt, and the outer wall of the nut abuts against the outer wall of the fixed disk.

[0012] As a preferred technical solution of this application, the detachable component includes a universal ball rotatably connected to the support plate, the base plate and the outer wall of the fixed block. A connecting frame is fixedly connected to the outer wall of the universal ball. A limiting sleeve is fixedly connected to the end of the connecting frame away from the universal ball. A limiting groove is formed on the outer wall of the limiting sleeve. A symmetrically distributed limiting block is slidably connected to the inner wall of the limiting groove. A screw is threadedly connected to the outer wall of the limiting sleeve. An extrusion plate is rotatably connected to the outer wall of the screw, and the outer wall of the extrusion plate abuts against the outer wall of the limiting block.

[0013] As a preferred technical solution of this application, a telescopic rod is fixedly connected between the symmetrical limiting blocks, and a strong spring is sleeved on the outer wall of the telescopic rod, and the outer wall of the strong spring abuts against the outer wall of the limiting sleeve.

[0014] As a preferred technical solution of this application, the inner wall of the drive disk is provided with uniformly distributed auxiliary grooves, and the auxiliary grooves are slidably connected to the auxiliary rods.

[0015] As a preferred technical solution of this application, the outer wall of the fixing sleeve is provided with a positioning groove, and the inner wall of the positioning groove is slidably connected to the bolt.

[0016] As a preferred technical solution of this application, a knob is fixedly connected to the end of the screw away from the extrusion plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. By connecting the base plate, support plate, and fixing block with detachable components, when maintenance of the strong spring is required, the connection between the limiting sleeve, limiting hole, telescopic rod, and limiting block allows for easy disassembly and replacement of the strong spring. This makes it easier for maintenance personnel to locate and handle spring problems, reducing maintenance difficulty, time, and labor costs. It ensures the continuous operation of water conservancy and hydropower projects and solves the problem in existing technologies where springs are constantly subjected to alternating stress caused by cable vibration in the complex and long-term operating environment of water conservancy and hydropower projects, which easily leads to fatigue and weakened elasticity. If a spring malfunctions, its installation location is relatively hidden and it is interconnected with other components, making disassembly and replacement difficult and costly, potentially affecting the continuous operation of the project.

[0020] 2. By using a guide clamping assembly that drives the clamping plate via a drive disc, the position of the clamping plate can be flexibly adjusted to accommodate cables of different diameters and shapes. Rotating the drive disc allows the clamping plate to be flexibly adjusted according to the shape and size of the cable, improving the versatility and applicability of the device. Simultaneously, it clamps the cable evenly at multiple angles, ensuring uniform clamping force and providing more stable fixation and protection. This solves the problem of limitations in existing technologies that use lower clamping plates, upper clamping plates, fastening screws, and arc-shaped pads to fix cables, which are unable to adapt to cables of different diameters and shapes and provide stable fixation and protection.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] like Figure 1-5 As shown, this embodiment proposes a cable fastening device for water conservancy and hydropower construction, including a support plate 1, with a base plate 2 and a fixing block 3 connected to the outer wall of the support plate 1 via a detachable component, and further including:

[0030] The guide clamping assembly includes a fixed sleeve 13 fixedly connected to the top wall of the fixed block 3. A fixed plate 14 is fixedly connected to the inner wall of the fixed sleeve 13. The outer wall of the fixed plate 14 is provided with evenly distributed sliding grooves 18. A slider 19 is slidably connected to the inner wall of the sliding groove 18. A drive rod 20 is fixedly connected to the outer wall of the slider 19. An auxiliary rod 22 is fixedly connected to the outer wall of the slider 19. A clamping plate 23 is fixedly connected to the end of the auxiliary rod 22 away from the slider 19. The drive rod 20 drives the slider 19 to slide along the sliding groove 18, thereby driving the auxiliary rod 22 to slide within the auxiliary groove 17, ultimately enabling the clamping plate 23 to perform the clamping or releasing action on the cable.

[0031] The drive assembly is located on the inner wall of the fixed sleeve 13, and the drive assembly cooperates with the guide clamping assembly.

[0032] like Figure 4-5As shown, in a preferred embodiment, based on the above method, the driving assembly further includes a driving disk 15 rotatably connected to the inner wall of the fixed sleeve 13. The outer wall of the driving disk 15 has evenly distributed driving grooves 21, and the inner wall of the driving grooves 21 abuts against the outer wall of the driving rod 20. A bolt 24 is fixedly connected to the outer wall of the driving disk 15, and a nut 25 is threadedly connected to the outer wall of the bolt 24. The outer wall of the nut 25 abuts against the outer wall of the fixed disk 14. When the driving disk 15 rotates, the driving grooves 21 push the driving rod 20 to move. When the driving disk 15 rotates to a suitable angle, the nut 25 is tightened. The position of the driving disk 15 can be locked by the cooperation of the bolt 24 and the nut 25. The positioning groove 16 guides and positions the bolt 24 to ensure the stability of the rotation of the driving disk 15.

[0033] like Figure 2-3 As shown, in a preferred embodiment, based on the above method, the detachable component further includes a universal ball 4 rotatably connected to the outer wall of the support plate 1, the base plate 2, and the fixing block 3. A connecting frame 5 is fixedly connected to the outer wall of the universal ball 4. A limiting sleeve 6 is fixedly connected to the end of the connecting frame 5 away from the universal ball 4. A limiting groove 26 is formed on the outer wall of the limiting sleeve 6. A symmetrically distributed limiting block 10 is slidably connected to the inner wall of the limiting groove 26. A screw 8 is threadedly connected to the outer wall of the limiting sleeve 6. The screw 8 is rotatably connected to the outer wall of the limiting sleeve 6. The device is equipped with a pressing plate 9, and the outer wall of the pressing plate 9 abuts against the outer wall of the limiting block 10. When it is necessary to disassemble and replace the strong spring 12, the screw 8 is rotated by turning the knob 7 to make the pressing plate 9 move away from the limiting block 10. When the limiting block 10 releases the pressing force, the limiting block 10 is rotated so that the limiting block 10 coincides with the other two sides of the cross groove of the limiting groove 26, which makes it easy to disassemble the telescopic rod 11. Then the strong spring 12 can be slid out along the telescopic rod 11. Conversely, the strong spring 12 can be replaced and installed.

[0034] like Figure 2 As shown, in a preferred embodiment, based on the above method, a telescopic rod 11 is fixedly connected between the symmetrical limiting blocks 10. A strong spring 12 is sleeved on the outer wall of the telescopic rod 11, and the outer wall of the strong spring 12 abuts against the outer wall of the limiting sleeve 6. The strong spring 12, in conjunction with the universal ball 4, offsets the impact force on the equipment and reduces the impact damage to the cable.

[0035] like Figure 4 As shown, in a preferred embodiment, based on the above method, the inner wall of the drive disk 15 is further provided with uniformly distributed auxiliary grooves 17, and the auxiliary grooves 17 are slidably connected to the auxiliary rod 22, so as to provide auxiliary guiding force for the movement of the auxiliary rod 22 through the auxiliary grooves 17.

[0036] like Figure 1As shown, in a preferred embodiment, based on the above method, the outer wall of the fixing sleeve 13 is provided with a positioning groove 16, and the inner wall of the positioning groove 16 is slidably connected to the bolt 24, so as to provide a guiding force for the movement of the bolt 24 through the positioning groove 16.

[0037] like Figure 2 As shown, in a preferred embodiment, based on the above method, a knob 7 is fixedly connected to the end of the screw 8 away from the extrusion plate 9, and the screw 8 is rotated by the knob 7.

[0038] Specifically, when using the cable fastening device intended for water conservancy and hydropower construction: when the drive disc 15 rotates, the drive groove 21 pushes the drive rod 20 to move. The drive rod 20 drives the slider 19 to slide along the slide groove 18, which in turn drives the auxiliary rod 22 to slide within the auxiliary groove 17. Ultimately, the clamping plate 23 clamps or releases the cable. When the drive disc 15 rotates to the appropriate angle, the nut 25 is tightened. The position of the drive disc 15 can be locked by the cooperation of the bolt 24 and the nut 25. The positioning groove 16 guides and positions the bolt 24, ensuring the stability of the drive disc 15's rotation. When it is necessary to disassemble and replace the strong spring 12, the screw 8 is rotated by turning the knob 7, causing the pressing plate 9 to move away from the limiting block 10. When the limiting block 10 releases the pressing force, the limiting block 10 is rotated so that it aligns with the other two sides of the cross groove of the limiting groove 26, thus facilitating the disassembly of the telescopic rod 11. Then, the strong spring 12 can be slid out along the telescopic rod 11. Conversely, the strong spring 12 can be replaced and installed.

[0039] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
