Description

Technical Field

[0001] This utility model relates to the field of cable engineering technology, and in particular to a sorting rack for underground cables in photovoltaic power stations. Background Technology

[0002] Underground cables are cables that are often buried underground, unlike common overhead lines. They are made of one or more insulated conductors covered with insulation and protective layers, and are used to transmit electricity or information from one place to another. When laying underground cables, tethering frames are used to prevent the cables from getting tangled.

[0003] Underground cable management racks typically refer to support and management systems used for underground cable laying. They are also known as cable management racks, cable fixing racks, or cable support racks. They help protect cables from soil pressure and external damage and are devices used to manage, fix, and protect cables.

[0004] Currently, when connecting and installing underground cables to the sorting rack, some methods still use bolts and hose clamps to fix the cables to the rack. This method is complicated to install, and it is also troublesome to remove the cables when they need to be dug up for maintenance. Another method is to use a support frame with slots to insert the cables into different slots for sorting. However, this method reduces the connection between the cables and the rack, making them prone to displacement and losing their limiting effect on the cables. Utility Model Content

[0005] In view of this, the present invention provides a cable management rack for underground photovoltaic power stations, which has a good cable fixing effect, is quick and easy to assemble and disassemble, and also has connection stability.

[0006] This utility model is achieved through the following technical solution: a cable management frame for buried photovoltaic power stations, comprising a connecting beam, a connecting frame, a mounting bracket, a drag frame, an extension rod, a rotating frame, and a clamping frame; both the drag frame and the clamping frame are arc-shaped structures, with two clamping frames located at opposite ends of the drag frame, the connecting frame located below the drag frame, the top end of the extension rod fixedly connected to the bottom of the drag frame, and the bottom end of the extension rod extending out of and being limited by the connecting frame; each of the two clamping frames is fixedly connected to one end of a corresponding rotating frame, and the other end of each rotating frame is limited within the connecting frame and engaged with the extension rod; initially... In the initial state, the two clamping frames are far apart, and the height of the end of the clamping frame closest to the end of the trailer is lower than the height of the ends of the trailer. After the cable is placed into the trailer, the two clamping frames are brought closer together by external force. The rotating frame drives the extension rod to move downward in a straight line, thereby driving the trailer to move downward in a straight line, so that the trailer and the two clamping frames form a ring structure. The ring structure is used to clamp the cable and limit it on the connecting frame. The connecting beam is fixed to the base by fasteners. The connecting beam has several vertical through holes, and the connecting frame is limited in the through holes by the bracket.

[0007] Furthermore, the connecting frame includes a base plate and a side plate, with a through hole in the center of the base plate; the extension rod has a toothed groove on its outer periphery, and the bottom end of the extension rod extends downward out of the base plate in cooperation with the through hole, with a limiting cone at the bottom end of the extension rod; the other end of the rotating frame has a gear that cooperates with the toothed groove of the extension rod, and the gear is rotatably connected to the side plate; the two clamping frames approach each other and drive the gear to rotate, thereby moving the extension rod downward.

[0008] Furthermore, the card holder consists of a fixed card holder and a movable card holder. Both the fixed card holder and the movable card holder are located in the through hole of the connecting crossbeam and are provided with grooves. The fixed card holder is fixed to the front end of the connecting crossbeam, and the movable card holder is connected to the rear end of the connecting crossbeam by bolts. Rotating the bolts causes the movable card holder to move closer to or away from the fixed card holder. After the movable card holder and the fixed card holder are joined together, the grooves inside the two form a fitting groove. A limiting rubber ring is provided in the fitting groove. The limiting cone of the extension rod passes through the limiting rubber ring and is limited by it. The fitting groove cooperates with the outer surface of the connecting frame, the limiting cone, and the gear.

[0009] Furthermore, a limiting spring is provided on the inner circumferential surface of the through hole in the bottom plate of the connecting frame. The limiting spring engages with the tooth groove of the extension rod to limit the upward movement of the extension rod.

[0010] Furthermore, the rear end of the connecting beam is provided with a threaded hole for bolt engagement. One end of the bolt passes through the threaded hole and is fixed to the movable retainer via a rotating seat, while the other end of the bolt is provided with a rotating disk.

[0011] Furthermore, a gasket is provided at the bottom of the base plate where it contacts the limiting rubber ring; a protective pad is provided at the bottom of the fitting groove.

[0012] Compared with existing technologies, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a bracket and a clamping bracket to enclose and confine the cable on the connecting bracket. Then, the connecting bracket is confined to the connecting beam by a clamping seat. Installation or removal is quick and convenient, and the stability between the cable and the connecting bracket, and between the connecting bracket and the connecting beam is ensured, which greatly avoids the occurrence of cable displacement.

[0014] 2. This utility model uses the cooperation of the extension rod and gears to make the bracket and clamping frame surround the cable in a ring structure. Then, the connecting frame is inserted into the fitting groove between the fixed bracket and the movable bracket. The limiting cone at the end of the extension rod cooperates with the limiting rubber ring in the fitting groove to ensure the stability of the connection between the connecting frame and the connecting beam. The movable bracket can move closer to or away from the fixed bracket by rotating the bolt, which makes it easier to install or remove.

[0015] 3. This utility model is equipped with a limiting spring that allows the extension rod to pass downward through its own elasticity, and restricts the extension rod from moving upward by engaging with the tooth groove of the extension rod. This can effectively prevent the extension rod from resetting when the connecting frame and the connecting beam are not connected, thus reducing the limiting effect on the cable.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] This utility model provides a cable management rack for underground photovoltaic power stations, such as... Figure 1 , 2 As shown, the sorting rack includes a connecting beam 1, a connecting frame 11, a card seat, a bracket 12, an extension rod 10, a rotating frame 8, and a clamping frame 9.

[0024] The cable carrier 12 and the two clamping brackets 9 can be combined to form a ring structure to clamp the cable. The ring structure is limited within the connecting frame 11 by the rotating frame 8 and the extension rod 10. The connecting frame 11 is limited on the connecting beam 1 by the clamping seat. The connecting beam 1 is used to fix the cable to the ground. The specific connection relationship is as follows:

[0025] Both the trailer 12 and the clamping frame 9 are arc-shaped structures, with the two clamping frames 9 located at opposite ends of the trailer 12. The connecting frame 11 is located below the trailer 12 and includes a base plate and side plates. The base plate has a through hole in the center, and the two side plates are parallel to each other and perpendicularly fixed to both sides of the base plate. The extension rod 10 has a toothed groove on its outer periphery. The top end of the extension rod 10 is fixed to the center of the trailer 12, and the bottom end of the extension rod 10 engages with the through hole in the base plate of the connecting frame 11, extending downwards through the through hole and out of the base plate of the connecting frame 11. A limiting cone 101 is provided at the bottom end of the extension rod 10.

[0026] like Figure 3 As shown, the two clamping frames 9 are respectively engaged with the two sides of the extension rod 10 through corresponding rotating frames 8. Specifically, one end of each of the two rotating frames 8 is fixedly connected to the middle of the two clamping frames 9, and the other end of the rotating frame 8 is provided with a gear 7 that meshes with the tooth groove of the extension rod 10. The axis of the gear 7 is parallel to the axis of the annular structure and perpendicular to the two side plates of the connecting frame 11. The gear 7 and the side plates are rotatably connected by a shaft.

[0027] Initially, the two clamping frames 9 are relatively far apart, and the height of the end of the clamping frame 9 near the end of the bracket 12 is lower than the height of the two ends of the bracket 12. After the cable is placed into the bracket 12, the two clamping frames 9 are brought closer together by external force. During this process, the rotating frame 8 is driven to rotate the gear 7, which in turn moves the extension rod 10 downward in a straight line. The downward movement of the extension rod 10 causes the bracket 12 to move downward, so that the bracket 12 and the two clamping frames 9 enclose a ring structure. The axis of the ring structure is the direction of cable extension. Finally, the ring structure hugs the cable and limits the cable on the connecting frame 11.

[0028] The two clamping frames 9 are primarily designed to be enclosed by the external force and the support frame 12. However, during the process, they are also subject to the weight of the cable: when the cable is placed into the support frame 12, the support frame 12 moves downwards due to the weight of the cable, causing the extension rod 10 to move downwards, thereby driving the gear 7 to rotate. This, through the rotating frame 8, brings the two clamping frames 9 closer together and tightens them. This process is additionally due to the clamping frames 9 being brought closer together and tightened by the external force. To ensure the limiting effect, both the support frame 12 and the inner side of the clamping frames 9 (the side that abuts against the cable) are provided with an anti-slip layer 13.

[0029] In this embodiment, a limiting spring 112 is provided on the inner circumferential surface of the through hole in the base plate of the connecting frame 11. The limiting spring 112 engages with the toothed groove of the extension rod 10. When the extension rod 10 is propelled outward from the base plate by the gear 7, the limiting spring 112 allows the extension rod 10 to pass through due to its elasticity, and through the engagement with the toothed groove, it simply limits the extension rod 10, restricting its upward movement and resetting. The limiting spring 112 can effectively prevent the extension rod 10 from resetting when it is not connected to the connecting beam 11, causing the gear 7 to actuate and loosen the clamping frame 9, thus affecting the connection effect between the connecting frame 11 and the cable. The limiting spring 112 limits the gear 7 through the extension rod 10, and the positioning effect of the clamping frame 9 is ensured by the rotating frame 8.

[0030] Both ends of the connecting beam 1 are provided with mounting bases 14, and each mounting base 14 has a mounting hole at its top. Fasteners are used to fix the connecting beam 1 to the base through the mounting holes. The connecting beam 1 has several vertical through holes 2, and the direction of the line connecting the through holes 2 is perpendicular to the direction of cable extension. The connecting bracket 11 is limited within the through holes 2 by a retainer. Specifically, as shown... Figure 4 As shown, the card holder consists of a fixed card holder 3 and a movable card holder 6. Both the fixed card holder 3 and the movable card holder 6 are located in the through hole 2 of the connecting beam 1 and are provided with grooves. The fixed card holder 3 is fixed to the front end of the connecting beam 1, and the movable card holder 6 is connected to the rear end of the connecting beam 1 by bolts 5. Rotating the bolts 5 causes the movable card holder 6 to move closer to or away from the fixed card holder 3. The moving direction of the movable card holder 6 is parallel to the extension direction of the cable.

[0031] After the movable bracket 6 approaches the fixed bracket 3 and mates, the internal grooves of the movable bracket 6 and the fixed bracket 3 combine to form a fitting groove. A limiting rubber ring 31 is provided in the fitting groove. The limiting cone 101 of the extension rod 10 can pass through the limiting rubber ring 31 and be limited by it. At the same time, the fitting groove cooperates with the base plate, side plate, limiting cone 101, and outer surface of gear 7 of the connecting frame 11 to limit the above components in the fitting groove. That is, the connecting frame 11, extension rod 10, and rotating frame 8 can be locked in the fitting groove. A protective pad 301 can also be provided at the bottom of the fitting groove. When the connecting frame 11 after the connecting cable is inserted into the fitting groove, the end of the limiting cone 101 passes through the limiting rubber ring 31 and abuts against the protective pad 301, which has a protective effect.

[0032] In this embodiment, the rear end of the connecting beam 1 is provided with a threaded hole to engage with a bolt 5. The bolt 5 passes through the threaded hole, and one end of the bolt 5 is fixedly connected to the movable bracket 6 via a rotating seat 51. The other end of the bolt 5 is provided with a rotating disk 51. Rotating the rotating disk 51 causes the bolt 5 to push the movable bracket 6 toward the fixed bracket 3, thereby merging the movable bracket 6 and the fixed bracket 3 to facilitate the positioning of the connecting frame 11. Reversing the rotating disk 51 causes the movable bracket 6 to separate from the fixed bracket 3, making it easy to remove the connecting frame 11.

[0033] A washer 111 may also be provided at the bottom of the base plate of the connecting bracket 11 where it abuts against the limiting rubber ring 31. For example... Figure 5 As shown, in this embodiment, an annular groove is opened at the bottom of the base plate and around the outer ring of the through hole. A gasket 111 is provided in the annular groove. After the limiting cone 101 of the connecting frame 11 is inserted into the limiting rubber ring 31, the gasket 111 on the base plate of the connecting frame 11 abuts against the limiting rubber ring 31 to prevent excessive deformation of the limiting rubber ring 31.

[0034] Working principle: The cable is placed on the bracket 12, and the clamping frame 9 is clamped towards the cable by external force, which drives the gear 7 to rotate. The gear 7 moves the extension rod 10 to extend out of the bottom plate of the connecting frame 11. At the same time, the bracket 12 moves with the extension rod 10 and finally cooperates with the clamping frame 9 to form a ring structure to hold the cable. After the extension rod 10 extends outward, the limiting spring 112 can limit the extension rod 10, thereby ensuring the connection between the ring structure and the cable. Rotate the bolt 5 to push the movable card 6 towards the fixed card 3 until they are merged. Insert the connecting frame 11 into the fitting groove between the fixed card 3 and the movable card 6. The limiting cone 101 will pass through the limiting rubber ring 31. The limiting rubber ring 31 is stuck between the limiting cone 101 and the bottom plate of the connecting frame 11. The connecting frame 11 is stuck in the fitting groove, completing the connection between the cable and the connecting beam 1.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
