Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power station construction and electrical installation technology, specifically a cable positioning and fixing device for photovoltaic power station collector line installation. Background Technology

[0002] In the installation of collector lines for photovoltaic power plants, cable positioning and securing are crucial for ensuring the safety and stability of the lines. Currently, some cable securing devices are available on the market, typically using clamps or straps to fix the cables. However, in practical applications, their structural designs are often ill-suited for cables of different specifications, and loosening or misalignment can easily occur during cable installation. Furthermore, some devices require additional tools during installation, increasing the complexity and time cost of the construction process.

[0003] For example, in some existing cable fixing devices, the main structure includes a base, a fixing bracket, and a clamping component. The base is provided with bolt holes for fixing the device to a support structure. The fixing bracket is connected to the base via a hinge, and the clamping component is connected to the fixing bracket via a threaded rod to achieve the function of clamping the cable. However, when dealing with the simultaneous deployment of multiple cables, this design often requires frequent adjustments to the position and force of the clamping component, resulting in low operating efficiency and an unsatisfactory fixing effect. The above situation can corroborate the limitations of the existing technology.

[0004] Therefore, we have made improvements to this and proposed a cable positioning and fixing device for the installation of photovoltaic power station collector lines. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of complex structure, cumbersome operation, and difficulty in adapting to different specifications of cables in the existing cable positioning and fixing devices during the installation of photovoltaic power station collection lines.

[0006] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a cable positioning and fixing device for photovoltaic power station collector line installation, comprising a support body and an adjustment component. The top of the support body is provided with a positioning plate, which has multiple through holes for accommodating cables. The adjustment component is located below the positioning plate and connected to it via a transmission mechanism. The adjustment component can adjust the height of the positioning plate according to the cable specifications, thereby achieving precise positioning and fixing of the cable. Sliding grooves are provided on both sides of the support body, and locking elements are installed within these grooves to fix the device to an external support structure.

[0007] The adjustment assembly includes an adjustment rod and a drive component. One end of the adjustment rod is threaded to the bottom of the positioning plate, and the other end is connected to the output end of the drive component. The drive component moves the positioning plate up and down by rotating the adjustment rod. The drive component includes a rotating handle and a gear set. The rotating handle is connected to the input end of the gear set, and the output end of the gear set meshes with the adjustment rod. The height of the positioning plate can be adjusted by manually rotating the rotating handle.

[0008] As a preferred technical solution of this application, the top of the positioning plate is provided with multiple elastic clamping blocks, which are located at the edge of the through hole and connected to the positioning plate by springs. When the cable passes through the through hole, the elastic clamping blocks open to both sides under the pressure of the cable and apply clamping force to the cable under the action of the springs, thereby achieving initial fixation of the cable.

[0009] As a preferred technical solution of this application, the inner surface of the elastic clamping block is provided with an anti-slip layer, which is made of a material with a high coefficient of friction and can effectively prevent the cable from sliding or shifting during the cable laying process.

[0010] As a preferred technical solution of this application, the bottom of the support body is provided with a base, and the base has a buffer cavity inside, which is filled with elastic material to absorb the influence of external vibration on the device, thereby improving the stability of the device. The base has symmetrical mounting holes on both sides, and bolts are installed in the mounting holes for fixing the device to the external support structure.

[0011] As a preferred technical solution of this application, a slider is provided inside the sliding groove, and the slider is fixedly connected to the locking member. The slider can move vertically within the sliding groove. A rack is provided on the side wall of the sliding groove, and the end of the locking member is provided with a locking tooth that engages with the rack. By rotating the locking member, the locking tooth can engage or disengage with the rack, thereby realizing the height adjustment and fixation of the device.

[0012] As a preferred technical solution of this application, the transmission mechanism includes a connecting rod and a guide column. One end of the connecting rod is hinged to the bottom of the positioning plate, and the other end is slidably connected to the guide column. The guide column is fixed to the inner wall of the support body. When the adjusting rod moves the positioning plate up and down, the connecting rod ensures that the positioning plate always remains horizontal through the limiting effect of the guide column, avoiding tilting caused by uneven force.

[0013] As a preferred technical solution of this application, the top of the support body is provided with a protective cover, which covers the positioning plate and is connected to the support body by screws. The inner side of the protective cover is provided with a guide channel to guide rainwater or other liquids out of the device surface, preventing liquid from seeping into the device and affecting its normal operation.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By incorporating adjustment components and a transmission mechanism, the height of the positioning plate can be flexibly adjusted to accommodate the needs of cable laying for different specifications. The coordinated design of the adjustment rod and drive component simplifies operation, allowing height adjustment without additional tools and significantly improving construction efficiency. The introduction of elastic clamping blocks and an anti-slip layer further enhances the device's ability to secure cables, effectively preventing loosening or displacement of cables during laying. The design of the sliding groove and locking component allows the device to be quickly fixed to an external support structure, while also providing height adjustment to meet the needs of different installation environments. Furthermore, the buffer cavity within the base and the guide channel design of the protective cover improve the stability and durability of the device, extending its service life. In summary, this invention solves the problems of complex structure, cumbersome operation, and poor adaptability in existing cable positioning and fixing devices, providing a more efficient and convenient solution for the installation of photovoltaic power station collector lines.

[0023] This utility model provides a cable positioning and fixing device for installing photovoltaic power station collector lines, the specific implementation of which is described in conjunction with the attached diagram. Figure 1 To be continued Figure 5 Detailed explanation follows. The supporting body 1 forms the frame structure of the entire device. A positioning plate 2 is mounted on its top, with multiple through holes 3 for accommodating cables. An adjustment assembly is located below the positioning plate 2, connected to it via a transmission mechanism. The transmission mechanism includes a connecting rod 16 and a guide post 17. One end of the connecting rod 16 is hinged to the bottom of the positioning plate 2, and the other end is slidably connected to the guide post 17, which is fixed to the inner wall of the supporting body 1. The adjustment assembly includes an adjustment rod 4 and a driving component 5. One end of the adjustment rod 4 is threaded to the bottom of the positioning plate 2, and the other end is in contact with the output end of the driving component 5. The driving component 5 includes a rotating handle 6 and a gear set 7. The rotating handle 6 is connected to the input end of the gear set 7, and the output end of the gear set 7 meshes with the adjusting rod 4. When the rotating handle 6 is manually rotated, the gear set 7 drives the adjusting rod 4 to rotate. The adjusting rod 4, through the threaded action, pushes the positioning plate 2 up and down, thereby achieving flexible adjustment of the height of the positioning plate 2.

[0024] The top of the positioning plate 2 is equipped with multiple elastic clamping blocks 8, which are located at the edge of the through hole 3 and connected to the positioning plate 2 by springs. When the cable passes through the through hole 3, the elastic clamping blocks 8 open to both sides under the pressure of the cable, while the springs exert a reaction force on the elastic clamping blocks 8, causing the elastic clamping blocks 8 to apply a clamping force to the cable, thereby achieving initial fixation of the cable. The inner surface of the elastic clamping blocks 8 is provided with an anti-slip layer 9, which is made of a high-friction coefficient material, and can increase the friction between the anti-slip layer and the cable, preventing the cable from sliding or shifting during cable laying.

[0025] The support body 1 has sliding grooves 12 on both sides, with locking elements 13 inside each groove. A slider is fixedly connected to the locking elements 13 inside the sliding grooves 12, allowing the slider to move vertically within the grooves. A rack 14 is provided on the side wall of the sliding grooves 12, and the end of the locking element 13 has a locking tooth 15 that engages with the rack 14. Rotating the locking element 13 allows the locking tooth 15 to engage or disengage with the rack 14, thus adjusting and fixing the device's height. When the device needs to be fixed to an external support structure, first adjust the device's height according to actual needs, then rotate the locking element 13 to engage the locking tooth 15 with the rack 14, thereby fixing the device in the desired position.

[0026] The base 10 is located at the bottom of the support body 1. Inside the base 10 is a buffer cavity 11 filled with elastic material to absorb the impact of external vibrations on the device and improve its stability. Mounting holes are symmetrically arranged on both sides of the base 10, and bolts are installed in these holes to fix the device to the external support structure. After the base 10 is fixed to the external support structure with bolts, the elastic material in the buffer cavity 11 effectively reduces the impact of external vibrations on the device, ensuring its stability during use.

[0027] A protective cover 18 is provided on the top of the support body 1, covering the positioning plate 2 and connected to the support body 1 by screws. A guide channel 19 is provided on the inner side of the protective cover 18 to guide rainwater or other liquids out of the device surface, preventing liquid from seeping into the device and affecting its normal operation. The design of the protective cover 18 not only protects the internal components of the device from the influence of the external environment, but also allows rainwater or other liquids to be quickly discharged through the guide channel 19, preventing water accumulation and damage to the device.

[0028] In practical applications, when it is necessary to position and fix the cables of the photovoltaic power station's collection lines, the device is first fixed to the external support structure through the mounting holes on the base 10. Then, according to the cable specifications, the handle 6 is manually rotated, which drives the adjusting rod 4 to rotate through the gear set 7. The adjusting rod 4 pushes the positioning plate 2 up and down until the height of the positioning plate 2 matches the cable laying requirements. During the adjustment of the height of the positioning plate 2, the connecting rod 16 and the guide column 17 ensure that the positioning plate 2 always remains horizontal, avoiding tilting due to uneven force. After the height of the positioning plate 2 is adjusted, the cable is passed through the through hole 3. The elastic clamping block 8 applies clamping force to the cable under the action of the spring, while the anti-slip layer 9 further enhances the fixing ability of the cable, preventing the cable from loosening or shifting position during the laying process. Finally, by rotating the locking piece 13, its locking teeth 15 are engaged with the rack 14 in the sliding groove 12, thereby fixing the device in the required position and completing the cable positioning and fixing operation.

[0029] This utility model achieves precise positioning and fixing of cables of different specifications through the rational design and arrangement of various components, while improving the ease of operation and adaptability of the device, and meeting the actual needs of photovoltaic power station collection line installation.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0031] During the installation of the photovoltaic power station's collector lines, the main support 1 is first fixed to the external support structure through the mounting holes on the base 10. The buffer cavity 11 inside the base 10 is filled with elastic material, which can absorb the impact force when the device is subjected to external vibration, thereby improving the overall stability. This design ensures the reliable operation of the device in complex environments, and is especially suitable for wind or mechanical vibration scenarios commonly encountered in photovoltaic power stations. After the base 10 is firmly fixed with bolts, the slider in the sliding groove 12 cooperates with the locking member 13 to adjust the height of the device to adapt to the actual wiring requirements. The side wall of the sliding groove 12 is provided with a rack 14, and the locking teeth 15 at the end of the locking member 13 engage or disengage with the rack 14 by rotation, thereby locking the device at the required height. This design not only simplifies the height adjustment process, but also ensures the stability of the device in the locked state.

[0032] Subsequently, the operator manually rotates the handle 6 in the drive unit 5 according to the cable specifications. The handle 6 drives the adjusting rod 4 to rotate via the gear set 7, and the adjusting rod 4 pushes the positioning plate 2 up and down through the threaded action. During this process, the connecting rod 16 and the guide post 17 in the transmission mechanism work together to ensure that the positioning plate 2 remains horizontal at all times. One end of the connecting rod 16 is hinged to the bottom of the positioning plate 2, and the other end slides along the guide post 17. The guide post 17 is fixed to the inner wall of the support body 1, thereby limiting the movement trajectory of the positioning plate 2 and preventing tilting due to uneven force. This design effectively solves the problem of uneven cable fixing caused by the tilting of the positioning plate in the prior art, significantly improving the adaptability and ease of operation of the device.

[0033] When the height of the positioning plate 2 is adjusted to suit the cable laying requirements, the cable is passed through the through hole 3. The elastic clamping blocks 8, located at the edge of the through hole 3, apply clamping force to the cable under the action of springs. The inner surface of the elastic clamping blocks 8 is covered with an anti-slip layer 9, made of a high-friction coefficient material, which increases the friction between the anti-slip layer and the cable, preventing the cable from slipping or shifting during laying. The design of the elastic clamping blocks 8 allows the device to adapt to cables of different diameters, eliminating the need for frequent clamp changes and further improving construction efficiency. Simultaneously, the introduction of the anti-slip layer 9 enhances the device's ability to fix the cable, ensuring the cable remains stable during laying.

[0034] Finally, by rotating the locking member 13, its locking teeth 15 are fully engaged with the rack 14 in the sliding groove 12, thereby fixing the device in the desired position. The protective cover 18 covers the positioning plate 2, and its inner drainage channel 19 guides rainwater or other liquids out of the device surface, preventing liquid from seeping into the device and affecting its normal operation. The design of the protective cover 18 not only protects the internal components of the device from external environmental influences but also allows for rapid drainage through the drainage channel 19, preventing water accumulation that could damage the device and extending its service life.

[0035] In summary, this invention achieves precise positioning and fixing of cables of different specifications through the design of the height-adjustable positioning plate 2, the elastic clamping block 8, and the anti-slip layer 9. Simultaneously, the cooperation between the sliding groove 12 and the locking element 13 ensures the adaptability of the device in different installation environments. The design of the buffer cavity 11 and the protective cover 18 further improves the stability and durability of the device, providing an efficient and reliable solution for the installation of photovoltaic power station collector lines.
