Description

Technical Field

[0001] This utility model relates to the field of cable fixing structure technology, and in particular to a photovoltaic cable fixing structure for a distributed photovoltaic power station. Background Technology

[0002] Distributed photovoltaic power stations often have a dispersed layout, with photovoltaic panels distributed over a large area. This means that photovoltaic cables need to be connected and routed in different locations, and the length and direction of the cables are complex and varied. For example, in a distributed photovoltaic power station in a residential area, photovoltaic panels may be installed on multiple rooftops, and cables need to be connected from each rooftop to a centralized inverter or distribution box, which places special requirements on the cable fixing structure.

[0003] Traditional clamping methods are mostly rigid structures, such as relying solely on the direct clamping of metal blocks and supporting structures. This rigid clamping structure cannot adaptively adjust to cables of different diameters or elasticities. When clamping cables is required, the lack of elastic buffer structures, such as gaskets and protective springs, easily leads to excessive compression. Excessive compression can damage the internal conductor structure of the cable or cause the cable sheath to rupture, thus affecting the cable's conductivity and lifespan, increasing safety hazards and maintenance costs of distributed photovoltaic power stations. Therefore, this application designs a photovoltaic cable fixing structure for distributed photovoltaic power stations to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixed structure for photovoltaic cables in distributed photovoltaic power stations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic cable fixing structure for a distributed photovoltaic power station, comprising an upper cover and a mating connector, wherein a connecting hinge is provided on one side of the mating connector, one end of the connecting hinge is fixed to the upper cover, and the other end of the connecting hinge is fixed to the mating connector, wherein a pressing and adjusting component is provided inside the upper cover and the mating connector, and a fixing connection component is provided on the other side of the mating connector.

[0006] Preferably, a cable threading sleeve for threading cables is snapped and fixed between the upper cover and the mating snap-fit ​​seat, and both the upper cover and the mating snap-fit ​​seat are provided with anti-slip pads for pressing the cable threading sleeve.

[0007] Preferably, the bottom of the mating connector is symmetrically provided with four mounting protrusions, and each mounting protrusion is provided with a bolt hole.

[0008] Preferably, the clamping adjustment assembly consists of an adjustment knob and a pressure block. The lower end of the adjustment knob is provided with a threaded sleeve, and a lifting threaded rod is threadedly connected to the threaded sleeve. The lower end of the lifting threaded rod is fixedly connected to the pressure block, and the lower end of the pressure block is provided with a clamping groove.

[0009] Preferably, a pad for pressing the cable is slidably provided on the mating contact seat at the lower end of the clamping groove, and a plurality of protective springs are equidistantly abutting the lower end of the pad.

[0010] Preferably, the fixed connection assembly consists of an upper buckle and a locking block. The upper buckle is fixedly installed on the upper cover, and the locking block is fixedly installed on the mating locking seat. The upper buckle is rotatably provided with an elastic buckle for mating the locking block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the cooperation between the cable threading sleeve and the fixed connection component can better fix the compressed cable, preventing the cable sheath from being dragged and damaged from the cable threading sleeve, thereby achieving the function of protecting the cable sheath. Furthermore, through the elastic protection cooperation between the pad and the protective spring, the pressing block and the spring support structure can form an elastic pressing and fixing structure, reducing the occurrence of rigid pressing and fixing of the pressing block and the spring support structure, thereby achieving the function of elastic pressing and protecting the cable. Finally, it solves the problem that the existing cable fixing structure is prone to excessive compression and damage to the cable when it is in the pressing state. Attached Figure Description

A connecting hinge 3 is provided on one side of the mating retaining seat 4, with one end of the connecting hinge 3 fixed to the upper cover 1 and the other end fixed to the mating retaining seat 4. A clamping adjustment component is provided inside the upper cover 1 and the mating retaining seat 4, and a fixing connection component is provided on the other side of the mating retaining seat 4. The upper cover 1 and the mating retaining seat 4 facilitate easier removal of cables from the device. The clamping base 4 is clamped and fixed with a cable threading sleeve 2 for threading cables. Both the upper cover 1 and the clamping base 4 are provided with anti-slip pads 9 for pressing the cable threading sleeve 2. The cable threading sleeve 2 can be clamped to prevent the cable from slipping and being pulled out under the action of external force. The bottom of the clamping base 4 is symmetrically provided with four mounting protrusions 11. Each mounting protrusion 11 is provided with bolt holes. The mounting protrusions 11 and bolt holes can better fix the device to the required position by bolts.

[0020] In this utility model, the clamping adjustment assembly consists of an adjustment knob 5 and a pressure block 7. The lower end of the adjustment knob 5 is provided with a threaded sleeve, and a lifting threaded rod 6 is threadedly connected to the threaded sleeve. The lower end of the lifting threaded rod 6 is fixedly connected to the pressure block 7. The lower end of the pressure block 7 is provided with a clamping groove. Through the setting of the clamping adjustment assembly, the clamping degree of the device on the cable can be easily adjusted. A pad 12 for clamping the cable is slidably provided on the mating contact seat 4 at the lower end of the clamping groove. Multiple protective springs 10 are equidistantly abutting the lower end of the pad 12. By setting the pad 12 and the protective spring 10, a certain elastic protection can be provided for the cable that is over-compressed, preventing the cable from being damaged by pressure; the fixed connection assembly consists of an upper buckle 8 and a locking block 13. The upper buckle 8 is fixedly installed on the upper cover 1, and the locking block 13 is fixedly installed on the mating locking seat 4.

[0021] Working principle: When using this utility model, firstly, a cable threading sleeve 2 is fitted onto the cable. The cable threading sleeve 2 clamps the cable passing through it, preventing it from slipping and being pulled out under external force. Next, the cable is placed in the clamping groove of the pressure block 7. Then, the upper cover 1 and the mating locking seat 4 are closed. Next, the elastic buckle 14 is pulled, causing it to engage with the locking block 13, thus completing the fixed connection between the upper cover 1 and the mating locking seat 4. Finally, the adjusting knob 5 is rotated to press down the pressure block 7 to fix the cable. The pad 12 and the protective spring 10 provide a certain elastic protection for the cable if it is over-pressed, preventing damage to the cable under pressure. The use of the device is then complete.
