Existing cable fixing devices include a positioning plate fixed to a bracket and a U-shaped fixing plate located above the positioning plate. The cable is placed on the positioning plate for positioning, and a driving mechanism is installed on the U-shaped fixing plate. This driving mechanism can move the U-shaped fixing plate along the height direction of the positioning plate, thereby clamping and locking the cable. However, this type of cable fixing device is suitable for fixing large-diameter, small-batch cables, but cannot simultaneously fix large quantities of small-diameter cables, and cannot meet the fixing needs of cables of various specifications.

[0044] 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 embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0046] According to an embodiment of this utility model, in one aspect, a cable pre-embedded fixing device for photovoltaic field areas is provided, including: a bracket 1 and a cable fixing assembly. The cable fixing assembly includes: a large-diameter cable fixing mechanism 21 and a small-diameter cable fixing mechanism 22; multiple sets of large-diameter cable fixing mechanisms 21 are spaced apart along the length direction of the bracket 1. Each large-diameter cable fixing mechanism 21 includes: a fixing frame 211, a first lifting mechanism 212, and a large-diameter cable fixing component 213. The fixing frame 211 is disposed on the bracket 1, and the first lifting mechanism 212 is disposed on the fixing frame 211, with its driving end connected to the large-diameter cable... The fastener 213 is connected, and the first lifting mechanism 212 is adapted to drive the large-diameter cable fastener 213 to move along the height direction of the bracket 1; a set of small-diameter cable fasteners 22 is provided between two adjacent sets of large-diameter cable fasteners 21. The small-diameter cable fastener 22 includes: a small-diameter cable fastener 221 and a second lifting mechanism 222. The two ends of the small-diameter cable fastener 221 are slidably connected to two fixed frames 211 respectively. The second lifting mechanism 222 is provided on the small-diameter cable fastener 221 and is adapted to drive the small-diameter cable fastener 221 to move along the height direction of the bracket 1.

[0047] Specifically, bracket 1 is a strip-shaped structure, its length extending along the width of the cable trench 5 in the photovoltaic field. Bracket 1 can be made of corrosion-resistant metal or engineering plastic to withstand long-term outdoor use. Bracket 1 has multiple cable mounting points for installing cable fixing components. The cable fixing components include multiple large-diameter cable fixing mechanisms 21 and multiple small-diameter cable fixing mechanisms 22. These are arranged such that a small-diameter cable fixing mechanism 22 is placed between two adjacent sets of large-diameter cable fixing mechanisms 21, thereby achieving distributed support and fixing of cables of different specifications.

[0048] Each set of large-diameter cable fixing mechanisms 21 can fix one large-diameter cable 6, and includes a fixing frame 211, a first lifting mechanism 212, and a large-diameter cable fixing component 213. The fixing frame 211 is fixedly installed on the bracket 1, and its shape is rectangular. In this embodiment, a rectangular frame structure is used to support and restrict the vertical movement of the large-diameter cable fixing component 213. The first lifting mechanism 212 is set on the fixing frame 211 and can drive the large-diameter cable fixing component 213 to move up and down along the height direction within the fixing frame 211, and press and fix the large-diameter cable 6 from the upper and lower sides through the bracket 1 and the large-diameter cable fixing component 213. Each set of small-diameter cable fixing mechanisms 22 can fix multiple small-diameter cables 7, and includes a small-diameter cable fixing component 221 and a second lifting mechanism 222. The two ends of the small-diameter cable fixing component 221 are respectively slidably engaged between two adjacent fixing frames 211 to form a transverse bridging structure. The second lifting mechanism 222 is installed on the small-diameter cable fixing member 221 and can drive the small-diameter cable fixing member 221 to move in the height direction of the bracket 1. Multiple small-diameter cables 7 can be placed between the two fixed frames 211. The bracket 1 and the small-diameter cable fixing member 221 can press and fix the small-diameter cables 7 on both sides.

[0049] The bracket 1 is equipped with a combination of large-diameter cable fixing mechanisms 21 and small-diameter cable fixing mechanisms 22, enabling distributed fixing of large-diameter cables 6 and small-diameter cables 7. Multiple sets of large-diameter cable fixing mechanisms 21 provide effective support and positioning for the large-diameter cables 6. The placement of small-diameter cable fixing mechanisms 22 between adjacent large-diameter cable fixing mechanisms 21 further accommodates the diverse deployment needs of small-diameter cables 7, optimizing cable arrangement and improving wiring neatness. Furthermore, both the large-diameter cable fixing component 213 and the small-diameter cable fixing component 221 can be adjusted along the height of the bracket 1. Maintenance personnel can adjust the positions of the large-diameter cable fixing component 213 and the small-diameter cable fixing component 221 according to the actual cable diameter, thereby achieving precise clamping and effective protection of the large-diameter cables 6 and small-diameter cables 7.

[0050] In one embodiment, the pre-embedded fixing device for cables in photovoltaic fields further includes an installation component 4, which includes an end seat 41 and a connector 42. One end of the connector 42 is connected to the end seat 41, and the other end is connected to one end of the bracket 1. The end seat 41 is adapted to be fixed to the side wall of the cable trench 5.

[0051] Specifically, the end seat 41 is fixed to the side wall of the cable trench 5, serving as the fixed base for the bracket 1. The end seat 41 can be made of metal or high-strength plastic, and its shape can be designed as a rectangle, L-shape, or arc shape according to the trench wall surface. In this embodiment, a rectangular structure is selected. The connector 42 is an intermediate connector, a rectangular connecting block. One end of the connector 42 is connected to the end seat 41 by screws, welding, or snap-fit, and the other end is connected to the bracket 1, ensuring a tight connection between the bracket 1 and the trench wall. The length and angle of the connector 42 can be adjusted as needed to adapt to different trench widths and layout angles, ensuring the overall installation level and structural stability of the bracket 1.

[0052] Furthermore, a reinforcing plate 44 is provided between the end seat 41 and the connector 42. The reinforcing plate 44 has a triangular cross-section, with one end fixedly installed on the top of the end seat 41 and the other end connected to the side of the connector 42 by welding or bolting. The reinforcing plate 44 can effectively improve the tensile and shear resistance of the entire connection part, while reducing the impact of external forces on the connection between the connector 42 and the end seat 41.

[0053] In one embodiment, the end base 41 is provided with a mounting groove 43.

[0054] The mounting groove 43 is located on the outer surface of the other end of the end seat 41. It is usually a rectangular or U-shaped groove. In this embodiment, a U-shaped groove is selected. The mounting groove 43 has mounting holes, which can be used to securely install it on the side wall of the cable trench 5 using expansion bolts or anchors.

[0055] In one embodiment, the other end of the bracket 1 is provided with an end cap 3.

[0056] Specifically, end cap 3 is fixedly installed at the end of bracket 1 away from end base 41. The height of end cap 3 is greater than the height of bracket 1, which can just block the cable being fixed and prevent the cable from slipping off bracket 1. The edge of end cap 3 is rounded to better fit bracket 1. End cap 3 can be integrally formed with bracket 1, or it can be connected and fixed to bracket 1 by welding, screws, rivets or clips to form a structural integration.

[0057] In one embodiment, a limiting block 214 is provided at the bottom of the fixed frame 211, and a limiting groove 12 is provided inside the bracket 1, with the limiting block 214 disposed inside the limiting groove 12.

[0058] Specifically, the limiting groove 12 is pre-set on the top surface of the bracket 1 along the length direction of the bracket 1, and can be a rectangular groove or a strip-shaped slot structure. The limiting block 214 is set at the bottom of the fixed frame 211. When the fixed frame 211 is installed on the bracket 1, the limiting block 214 is inserted into the limiting groove 12 to form a fitting connection, thereby preventing the fixed frame 211 from sliding laterally or shifting position.

[0059] In one embodiment, the first lifting mechanism 212 includes a first screw 2121 and a first operating handle 2122. One end of the first screw 2121 passes through the fixed frame 211 and is connected to the large-diameter cable fixing member 213. The other end of the first screw 2121 is connected to the first operating handle 2122.

[0060] Specifically, the first screw 2121 is vertically oriented, passes through the upper surface of the fixed frame 211, and is screwed to the fixed frame 211. A snap-fit ​​hole is provided on the upper part of the large-diameter cable fixing component 213, and the lower end of the first screw 2121 is inserted into the snap-fit ​​hole to snap into the large-diameter cable fixing component 213. A first operating handle 2122 is located on the upper end of the screw, facilitating manual operation by maintenance personnel. In use, maintenance personnel can rotate the first operating handle 2122 clockwise or counterclockwise to rotate the first screw 2121, driving the large-diameter cable fixing component 213 to rise and fall along the height of the bracket 1, thus tightening or releasing the large-diameter cable 6.

[0061] In one embodiment, the large-diameter cable fastener 213 is an arc-shaped plate.

[0062] Specifically, the inner surface of the arc plate is an arc-shaped concave surface that matches the outer circular surface of the large-diameter cable 6, which can achieve a larger area of ​​contact when pressed, effectively disperse the contact pressure, and avoid causing indentations or damage to the cable sheath.

[0063] Correspondingly, the lower support 1 of the arc plate is designed with an arc-shaped groove 13 that matches the arc plate. The arc-shaped groove 13 is a curved arc-shaped slot structure that can fit the outer edge surface of the large-diameter cable 6 and ensure the fixing effect.

[0064] The curved plate can be made of rigid materials such as aluminum alloy and stainless steel. A flexible rubber pad or elastic buffer layer can be adhered to its inner surface to enhance anti-slip and buffer properties, thereby further improving the protection of large-diameter cables.

[0065] In one embodiment, the small-diameter cable fastener 221 is an I-beam.

[0066] Specifically, the longitudinal extension of the I-beam serves as the cable holding area, while the transverse extensions at both ends are used for sliding connection with the adjacent fixed frame 211, thereby achieving transverse support and stable installation of the small-diameter cable fixing component 221 between the fixed frames 211.

[0067] The I-beam structure has good rigidity and bending resistance. The vertical plate in the middle provides strong downward pressure when clamping the cable, while the transverse plates on both sides enhance the stability of the sliding connection with the fixed frame 211. During the installation of the small-diameter cable 7, the maintenance personnel lay it in the rectangular groove 11 and adjust the second lifting mechanism 222 to press the cable tightly from top to bottom, thus completing the fixation.

[0068] In one embodiment, the second lifting mechanism 222 includes: a second screw 2221 and a second operating handle 2222. One end of the second screw 2221 passes through a small-diameter cable fixing member 221 and is connected to a cable fixing assembly. The other end of the second screw 2221 is connected to the second operating handle 2222.

[0069] Specifically, the second screw 2221 is vertically oriented, with its lower end connected to the bracket 1 via a threaded connection, and its upper end passing through the small-diameter cable fixing component 221, and fixedly connected to the second operating handle 2222, forming a movable connection with the small-diameter cable fixing component 221. Maintenance personnel can manually rotate the second operating handle 2222, causing the second screw 2221 to move the small-diameter cable fixing component 221 up and down along the height of the bracket 1, thereby clamping or releasing the cable.

[0070] In another embodiment, the second lifting mechanism 222 can also be replaced by a spring-locking structure. Specifically, a spring lock is provided on the small-diameter cable fixing part 221, and a spring locking pin is provided on the corresponding rectangular groove 11. The maintenance personnel place the small-diameter cable 7 in the rectangular groove 11, press the small-diameter cable fixing part 221 downward to lock it with the spring locking pin on the rectangular groove 11, thereby fixing the small-diameter cable 7.

[0071] In one embodiment, a rectangular groove 11 is provided on the bracket 1, which is located directly below the small-diameter cable fixing member 221 and is used to place the small-diameter cable 7.

[0072] Specifically, the rectangular groove 11 extends along the length of the bracket 1, and its dimensions are designed to match the outer diameter of the small-diameter cable 7, ensuring that the small-diameter cable 7 can be stably embedded in the rectangular groove without shaking or slipping. The rectangular groove 11 can be formed on the bracket 1 in one step by using a mold or by post-processing, providing sufficient embedding space for the small-diameter cable 7 without affecting the overall strength of the bracket 1. A flexible pad or insulating liner can be provided at the bottom of the rectangular groove 11 as needed to enhance the buffering and support effect of the cable.

[0073] By setting a rectangular groove 11 on the bracket 1, the small-diameter cable 7 is initially positioned and limited. Combined with the clamping action of the small-diameter cable fixing component 221, a double fixing structure is constructed, which improves the stability and protection of the small-diameter cable 7.

[0074] In other embodiments, the rectangular groove 11 can also be replaced with grooves of other shapes, such as small-diameter U-shaped or semi-circular grooves arranged in an array along the length of the bracket 1. The U-shaped or semi-circular grooves match the diameter of the small-diameter cable 7 and can clamp and fix the small-diameter cable 7.

[0075] Operating procedure: First, the bracket 1 is fixed to the side wall of the cable trench 5 via the end seat 41 and connector 42. Then, a large-diameter cable 6 is laid in the arc-shaped groove 13 on the bracket 1 as required. The fixing frame 211 is aligned above the large-diameter cable 6 and snapped into the bracket 1. The first screw 2121 is driven to tighten and fix the large-diameter cable fixing component 213. Subsequently, multiple small-diameter cables 7 are laid in the rectangular groove 11 on the bracket 1. The small-diameter cable fixing component 221 is aligned above the rectangular groove 11, with both ends pressed against the fixing frame 211. The second screw 2221 is driven to fix the small-diameter cables 7. The design of the limiting block 214 and the limiting groove 12 ensures that the fixing frame 211 will not shift, and the cable is always securely clamped in the bracket 1.

[0076] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
