The most common laying method is direct burial cable laying, which requires the cables to be buried underground. When connecting two sections of cable, the joint in the middle of the cable cannot be buried directly, and must be processed before it can be buried underground. The common processing method is usually to use cable accessories and add insulating waterproof glue for protection.

[0003] According to the Chinese patent with publication number: CN218498730U, it includes an upper shell body, a lower shell body is provided on the lower surface of the upper shell body, relative circular grooves are provided on both sides of the upper shell body and the lower shell body, fixing bolts are provided in the circular grooves on both sides of the upper shell body and the lower shell body, upper shell calipers are provided at both ends of the upper shell body, one end of the upper shell caliper is provided with a movable bolt, lower shell calipers are provided at both ends of the lower shell body, strip blocks are provided on one side of both ends of the lower shell caliper, movable grooves are provided at one end of the strip blocks at both ends of the lower shell caliper away from the lower shell caliper, movable bolts are provided in the movable grooves of the strip blocks at both ends of the lower shell caliper, and rollers are provided on the outside of the movable bolts.

[0004] In the above scheme, the upper and lower shell bodies are used to protect the cables inside, which still has the following disadvantages: the upper and lower shells can only protect the surface of the cable, and may not play a protective role for the exposed end of the cable, thereby reducing the safety of the cable when it is laid. Utility Model Content

[0005] The utility model aims to provide a photovoltaic panel cable laying protection device to solve the problem that the exposed end of the cable may not be protected, thereby reducing the safety of the cable when it is laid.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a photovoltaic panel cable laying protection device, including a protective cover, which is detachably arranged at one end of a cable body, a storage groove is provided on a side of the protective cover close to the cable body, a plurality of limit strips are fixed on the surface of the cable body, a plurality of installation grooves are provided on the inner wall surface of the storage groove, an elastic U-plate is fixed on one side of the inner side of the installation groove, and a blocking strip is fixed on one side of the elastic U-plate.

[0007] Preferably, a protective ring is provided on the outside of the cable body, two connecting plates are fixed on one side of the protective ring, a roller is rotatably provided between the two connecting plates, rotating columns are respectively fixed at both ends of the roller, a rotating hole is opened on one side of the connecting plate, and the rotating hole is rotatably inserted with the rotating column.

[0008] Preferably, two fixing plates are fixed to one side of the protection ring, a threaded hole is opened on one side of the fixing plate, and a fixing bolt is connected to the inner thread of the threaded hole.

[0009] Preferably, a protective sleeve is slidingly sleeved on the surface of the cable body, an elastic sleeve is sleeved outside the protective sleeve, and a corrugated sleeve is fixed between the protective sleeve and the elastic sleeve.

[0010] Preferably, the protective sleeve, the elastic sleeve and the corrugated sleeve are all made of degradable plastics.

[0011] Preferably, the elastic U-plate is made of phosphor bronze, and the limiting strip and the blocking strip are both made of rubber.

[0012] Compared with the prior art, a photovoltaic panel cable laying protection device using the above technical solution has the following beneficial effects:

[0013] 1. The staff will first install one end of the cable body into the storage slot. As the distance of one end of the cable body entering the storage slot increases, the elastic U plate will be squeezed and bent, reducing the angle of the elastic U plate, and the squeezed and bent elastic U plate will be used to apply an extrusion force to the surface of one end of the cable body. Finally, the blocking bar will pass over the limit bar. The limit bar is used to prevent the blocking bar from moving on the cable body, so that the protective cover can be covered on one end of the cable body, increasing the safety of the forward end of the cable body during laying;

[0014] 2. The staff will first install the protective ring at one end of the sleeve. During the installation process, the staff will first move the protective ring to one end of the sleeve. At this time, the sleeve is between the two fixing plates. Then the staff will control the fixing bolt to screw into the threaded hole. The screwed fixing bolt will eventually squeeze the surface of the sleeve, and the protective ring can be fixed to one end of the sleeve. When the cable body passes through the protective ring and moves inside the sleeve, the surface of the cable body will contact the surface of the roller. The support of the roller can prevent the edge of the sleeve from scratching the surface of the cable body.

[0015] 3. During the laying process of the cable body, the surface of the cable body may be bumped and worn. In order to protect the surface of the cable body, the staff will first put the protective sleeve on the surface of the cable body, which can drive the corrugated sleeve and the elastic sleeve to be also put on the surface of the cable body. The corrugated sleeve increases the elasticity of the elastic sleeve, reduces the impact force on the cable body during use, and prevents the cable body from being damaged due to impact.
