Description

Technical Field

[0001] This utility model belongs to the field of cable fixing equipment, and specifically relates to a cable fixing bracket for hydropower equipment. Background Technology

[0002] Hydropower stations are key facilities for converting water energy into electrical energy. This energy conversion is typically achieved through turbine generator units, which then transmit the electricity to the power grid, providing a stable power supply for industrial production and residential life. Cables, as crucial facilities for connecting various equipment and transmitting electrical energy in hydropower stations, are numerous and vary in specifications. They also need to be laid systematically within the complex space of the hydropower station. Therefore, cable fixing brackets are required to position and support these cables.

[0003] However, due to the thermal expansion and contraction of cables, prolonged exposure to excessively high temperatures can cause the cable supports to expand and compress, while prolonged exposure to excessively low temperatures can lead to gaps and loosening. In other words, cable supports cannot adapt to changes in cable dimensions. This results in ordinary cable supports failing to provide continuous and stable support for the cable.

[0004] To address the problems of existing cable fixing brackets, patent CN206712383U discloses a cable fixing bracket that uses two clamping rings with adjustable clamping force to adapt to cable size changes due to seasonal variations. However, this patent only addresses the routine operation scenario after cable fixing, and its support frame is directly fixed to the wall panel. This cannot meet the needs of adjusting distance and height during cable installation, leading to excessive stretching or bending of the cable after installation. Excessive stretching subjectes the cable conductor to additional tension, easily causing localized overheating, aging, or even conductor breakage. Excessive bending affects cable performance, increases the risk of short circuits and leakage, and makes it difficult to guarantee the cable's service life and safety. Therefore, there is an urgent need for a cable fixing bracket that can solve the above problems. Utility Model Content

[0011] Furthermore, the first adjustment mechanism also includes an adjustment handle disposed on the same side as the positioning hole; the pin assembly includes a pin and a first spring; the pin is movably mounted on the adjustment handle via the first spring and can move horizontally relative to the adjustment handle; the first spring is used to maintain the pin's tendency to move towards and insert into the positioning hole using its own elasticity.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to the following embodiments.

[0033] Example 1:

[0034] See attached Figure 1 , 5A cable fixing bracket for hydroelectric equipment includes a bracket box 1, an adjusting mechanism 2, and two wiring units movably mounted on the adjusting mechanism 2. The adjusting mechanism 2 is located on the bracket box 1 and is used to drive the two wiring units to move synchronously closer or further apart along the length of the bracket box 1. Each wiring unit includes a first adjusting mechanism 3 and a fixing structure 4 connected above the first adjusting mechanism 3. The first adjusting mechanism 3 is used to adjust the relative height of the fixing structure 4 with respect to the ground. The fixing structure 4 includes a fixed upper part 41, a fixed lower part 42, and a second adjusting mechanism 43. The fixed upper part 41 is movably mounted above the fixed lower part 42 via the second adjusting mechanism 43. The second adjusting mechanism 43 is used to adjust the vertical distance between the fixed upper part 41 and the fixed lower part 42. From the above structure, it can be seen that the bracket box 1 serves as the mounting base for the entire device and can be fixed in a preset installation position. The adjusting mechanism 2, located on the bracket box 1, is used to drive the two wiring units to move synchronously closer or further apart along the length of the bracket box 1, thereby adjusting the relative horizontal distance between the two wiring units. Each wiring unit can install and fix a set of cables. The wiring unit specifically includes a first adjusting mechanism 3 and a fixing structure 4. The first adjusting mechanism 3 is used to adjust the relative height of the fixing structure 4 to the ground, while the fixing structure 4 is specifically used to provide fixation and support for the cables. This invention, through the adjusting mechanism 2 and the first adjusting mechanism 3, can adjust the relative horizontal and vertical distance between each set of cables during installation, preventing excessive stretching or bending of the cables during installation and ensuring suitable cable installation positions. Specifically, the fixing structure 4 includes a fixed upper part 41, a fixed lower part 42, and a second adjusting mechanism 43. The fixed upper part 41 is movably installed above the fixed lower part 42 via the second adjusting mechanism 43. The second adjusting mechanism 43 is used to adjust the vertical distance between the fixed upper part 41 and the fixed lower part 42, accommodating the thermal expansion and contraction of the cables, ensuring that the cable fixing bracket can continuously and stably provide fixation and support for the cables during long-term use, without expansion, compression, or loosening.

[0035] Preferably, several ear plates can be provided on the outer peripheral wall of the bracket box 1 to fix the bracket box 1 in a designated position by mechanical connection, thereby further ensuring installation stability.

[0036] Example 2:

[0037] See attached Figures 1-4Based on Embodiment 1, the adjusting mechanism 2 includes a bidirectional threaded rod 21, a drive assembly 22, and two connecting sliders 23. The bidirectional threaded rod 21 is rotatably arranged along the length of the support box 1. The drive assembly 22 is used to drive the bidirectional threaded rod 21 to rotate circumferentially. The two connecting sliders 23 are respectively movably sleeved on the left and right sides of the bidirectional threaded rod 21, and are used to synchronously move closer or further away from each other when the bidirectional threaded rod 21 rotates circumferentially. The tops of the two connecting sliders 23 are respectively connected to a wiring unit. As can be seen from the above structure, in the adjusting mechanism 2, the bidirectional threaded rod 21 is rotatably arranged along the length of the support box 1, and specifically, one end of the bidirectional threaded rod 21 can extend beyond the left or right side wall of the support box 1 to connect with the drive assembly 22. The drive assembly 22 is used to drive the bidirectional threaded rod 21 to rotate circumferentially along its central axis. The drive assembly 22 can be an electric servo motor, a pneumatic cylinder assembly, or a manual drive assembly such as a rocker arm, etc. The specific implementation method is prior art and will not be described here. Two connecting sliders 23 are respectively movably sleeved on the left and right sides of the bidirectional threaded rod 21, and are used to move closer or further away from each other synchronously when the bidirectional threaded rod 21 rotates in the circumferential direction, thereby changing the relative horizontal distance between the two wiring units connected to the top of the connecting sliders 23.

[0038] The bidirectional threaded rod 21 has two external threads with opposite directions on its left and right sides respectively; the connecting slider 23 has an internal thread through hole along its length, and the thread direction of the two internal thread through holes of the connecting slider 23 matches the two external threads of the bidirectional threaded rod 21 respectively. As can be seen from the above structure, since the two external threads on the left and right sides of the bidirectional threaded rod 21 have opposite directions of rotation and are respectively fitted with matching connecting sliders 23, during the rotation of the threaded rod, the two connecting sliders 23 will generate axial displacements in opposite directions due to the threaded transmission, thereby achieving the function of synchronously moving closer or further apart.

[0039] The drive assembly 22 includes a worm gear 221, a worm 222, and a turntable 223. One end of the bidirectional threaded rod 21 extends beyond one side wall of the support box 1 and is connected to the worm gear 221. A limiting plate 11 is also provided on the side wall of the support box 1 on the same side as the worm gear 221. The worm 222 is rotatably mounted on the limiting plate 11 and meshes perpendicularly with the worm gear 221. The turntable 223 is located at the top of the worm 222 and above the limiting plate 11. As can be seen from the above structure, as an implementation of the drive assembly 22, the drive assembly 22 of this utility model includes a worm gear 221, a worm 222, and a turntable 223. Specifically, the limiting plate 11 is used to movably mount the worm 222, the worm gear 221 is sleeved on the outer peripheral wall of the end of the bidirectional threaded rod 21 extending beyond the support box 1, and the worm gear 221 and the worm 222 mesh perpendicularly. When the operator manually rotates the turntable 223, the turntable 223 drives the worm gear 222 to rotate synchronously. Since the worm gear 222 is perpendicularly engaged with the worm wheel 221, the worm wheel 221 also rotates simultaneously, ultimately driving the bidirectional threaded rod 21 connected to the worm wheel 221 to rotate circumferentially, thereby adjusting the horizontal distance between the two connecting sliders 23. This setting allows the operator to adaptively adjust the horizontal distance between the two wiring units according to specific cable installation requirements.

[0040] Example 3:

[0041] See attached Figures 1-4 Based on Embodiment 2, the first adjustment mechanisms 3 of the two wiring units are symmetrically arranged; the first adjustment mechanism 3 includes a positioning housing 31, a sliding block 32, and a pin assembly; the positioning housing 31 has a plurality of positioning holes 34 arranged in a row on one side wall; the sliding block 32 is slidably fitted into the positioning housing 31; the sliding block 32 is provided with a plurality of positioning grooves 321, and when the bottom of the sliding block 32 contacts the bottom wall of the positioning housing 31, the positioning grooves 321 correspond one-to-one with the positioning holes 34; the pin assembly adjusts the height of the sliding block 32 relative to the positioning housing 31 by changing the position of the inserted positioning hole 34 and the positioning groove 321. From the above structure, it can be seen that the first adjustment mechanisms 3 of the two wiring units are symmetrically arranged. And according to the appendix... Figure 2 , 3It can be seen that the sidewalls of the two positioning housings 31 can be the left and right sidewalls shown in the figure, respectively. That is, the positioning housings 31 have the positioning holes 34 positioned opposite each other on the outer side to facilitate independent adjustment of the height of the fixing structure 4 of the wiring unit. The sliding block 32 is slidably engaged in the positioning housings 31 and can slide up and down relative to each other. Specifically, the top of the sliding block 32 extends beyond the top of the positioning housings 31 and connects to the lower fixing part 42. The sliding block 32 adjusts its own height to change the height of the fixing structure 4 relative to the ground to meet the installation height requirements of the cable. The operator can adjust the height of the sliding block 32 relative to the positioning housings 31 to change the positioning groove 321 aligned with the positioning hole 34. Then, the pin assembly is inserted into one of the positioning holes 34 and the aligned positioning groove 321 simultaneously to fix the relative position between the sliding block 32 and the positioning housings 31, thus completing the height adjustment and fixing.

[0042] The first adjustment mechanism 3 further includes an adjustment handle 33 disposed on the same side as the positioning hole 34; the pin assembly includes a pin 35 and a first spring 36; the pin 35 is movably mounted on the adjustment handle 33 via the first spring 36 and can move horizontally relative to the adjustment handle 33; the first spring 36 is used to maintain the pin 35's tendency to move towards and insert into the positioning hole 34 using its own elasticity. From the above structure, it can be seen that the pin 35 is movably mounted on the adjustment handle 33 via the first spring 36 and can move outward and inward relative to the adjustment handle 33 in the horizontal direction, thereby realizing the operation of leaving and inserting into the positioning hole 34. The first spring 36 is used to provide the pin 35 with elastic deformation capability, specifically, as shown in the attached... Figure 3 As shown, the first spring 36 can be disposed between the positioning housing 31 and the adjusting handle 33, and sleeved on the outer peripheral wall of the pin 35. One end of the first spring 36 is fixed to the outer wall of the pin 35, and the other end can movably abut against the side wall of the positioning housing 31 or the adjusting handle 33 on the side away from the outer wall of the pin 35. When the operator pulls the pin 35 outward, the pin 35 will drive the first spring 36 to compress when pulled outward, and keep the pin 35 in a reset tendency to move closer to and insert into the positioning hole 34.

[0043] Example 4:

[0044] See attached Figures 1-6Based on Embodiment 3, the upper fixed part 41 and the lower fixed part 42 are respectively provided with a plurality of first grooves 411 and a plurality of second grooves 421 along the width direction; the plurality of first grooves 411 are evenly arranged along the length direction of the upper fixed part 41; the number and position of the first grooves 411 and the second grooves 421 correspond one-to-one, and the concave directions are opposite. From the above structure, it can be seen that the first grooves 411 and the second grooves 421 can specifically be semi-circular grooves, used to adapt to the shape of the cable. The plurality of first grooves 411 are evenly arranged along the length direction of the upper fixed part 41, and similarly, the plurality of second grooves 421 are evenly arranged along the length direction of the lower fixed part 42, and the number and position of the first grooves 411 and the second grooves 421 correspond one-to-one, and the concave directions are opposite. This utility model uses the first grooves 411 and the second grooves 421 to approach and clamp the cable from both ends, thereby completing the installation and fixation of the cable.

[0045] Anti-slip pads 44 are provided on the inner walls of both the first cable tray 411 and the second cable tray 421. As can be seen from the above structure, the anti-slip pads 44 can increase the friction between the cable and the first cable tray 411 and the cable and the second cable tray 421, preventing the cable from becoming loose after installation.

[0046] Example 4:

[0047] See attached Figures 1-6 Based on Embodiment 3, the top of the fixed upper part 41 is also provided with a wiring handle 412; the second adjustment mechanism 43 includes four height adjustment components; the height adjustment components include at least a connecting column 431; the lower end of the connecting column 431 is movably installed on the fixed lower part 42 and can move vertically relative to the fixed lower part 42, and the upper end is connected to the bottom wall of the fixed upper part 41; the four connecting columns 431 are respectively located at the four corners between the fixed upper part 41 and the fixed lower part 42. As can be seen from the above structure, four height adjustment components are movably disposed between the fixed upper part 41 and the fixed lower part 42. Specifically, the fixed upper part 41 and the fixed lower part 42 are movably connected by four connecting posts 431. By pulling the wiring handle 412 upward, the connecting posts 431 connected to the bottom wall of the fixed upper part 41 move upward, changing the vertical height of the fixed upper part 41 relative to the fixed lower part 42. When the distance between the fixed upper part 41 and the fixed lower part 42 is sufficient, the cable can be placed or removed. In addition, the four connecting posts 431 are located at the four corners between the fixed upper part 41 and the fixed lower part 42 to form a four-corner support structure, ensuring the stability of the support for the fixed upper part 41.

[0048] The fixed lower part 42 has four corners with receiving cavities 422, and each receiving cavity 422 has an opening at its top. The height adjustment assembly also includes a sliding plate 432 and a second spring 433. The upper end of the connecting column 431 extends beyond the receiving cavity 422, and the lower end fits inside the receiving cavity 422 and is connected to the sliding plate 432. The opening size is smaller than the size of the receiving cavity 422 and larger than the size of the connecting column 431. The second spring 433 is sleeved on the outer peripheral wall of the connecting column 431, and its upper and lower ends abut against the top wall of the receiving cavity 422 and the top wall of the sliding plate 432, respectively. As can be seen from the above structure, the fixed lower part 42 has four corners with receiving cavities 422, which are used to accommodate the lower part of the connecting column 431, the sliding plate 432, and the second spring 433. When cable installation is required, the operator can first manually pull the wiring handle 412 of the fixed upper part 41 upwards to move the connecting post 431 upwards. At this time, the sliding plate 432 at the lower end of the connecting post 431 will also slide upwards within the receiving cavity 422. Since a second spring 433 is sleeved on the outer periphery of the connecting post 431, and the upper and lower ends of the second spring 433 are respectively pressed against the top wall of the receiving cavity 422 and the top wall of the sliding plate 432, the sliding plate 432 continuously moves upwards as the fixed upper part 41 moves away from the fixed lower part 42. The second spring 433 is in a state of continuous compression within the receiving cavity 422, and at this time, the second spring 433 always maintains a downward reset tendency. When the height distance between the fixed upper part 41 and the fixed lower part 42 is sufficient, the cable can be placed into the first cable tray 411 and the second cable tray 421. Once the cable is in place, the operator can release the connection handle 412. The second spring 433 will release its elastic potential energy, pushing the slide plate 432 downwards within the receiving cavity 422. This, in turn, causes the connecting post 431 to move downwards, bringing the upper fixed part 41 closer to the lower fixed part 42 until the cable is clamped, completing the installation. Although cables experience thermal expansion and contraction, when the cable expands due to high temperatures or contracts due to low temperatures, the height adjustment component can automatically adjust the distance between the upper fixed part 41 and the lower fixed part 42 based on the reaction force of the cable and gravity. This adapts to changes in the cable, ensuring that the fixing structure 4 can stably clamp the cable for a long time without loosening or compression. Furthermore, the opening size at the top of the receiving cavity 422 is smaller than the cavity size, limiting the upper limit of the slide plate 432's displacement, preventing the connecting post 431 from detaching from the receiving cavity 422. The opening size is also larger than the connecting post 431, allowing the upper end of the connecting post 431 to extend beyond the receiving cavity 422 and move vertically.

Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
