A connecting rod 9 is fixed to the right side of the two limiting blocks 8, and a first fixing plate 10 is fixed to the right end of the two connecting rods 9. An adjusting mechanism is fixed to the right ends of the two first fixing plates 10. According to the length of the cable sinking, if it is too long (the length to be wound is longer), it is necessary to adjust the distance between the two first fixing plates 10 through the adjusting mechanism to increase the distance, so that a longer cable can be wound. If the sinking length is shorter (the length to be wound is shorter), the distance between the two first fixing plates 10 can be shortened, and the two first fixing plates 10 can only move up and down under the limiting action of the first limiting rod 7 and the limiting block 8. Symmetrical baffles 11 are fixed to the front sides of the two first fixing plates 10, and the side walls of the two groups of symmetrical baffles 11 are provided with a pressing mechanism. A second fixing plate 12 is fixed to the side close to the two groups of symmetrical baffles 11, and a winding rod 13 is fixed to the side wall of the second fixing plate 12. Specifically, the cable is wound by the cooperation of the baffle rod 11 and the winding rod 13: the two baffle rods 11 located at the front end of the upper first fixed plate 10 are baffle rod No. 1 and baffle rod No. 2 respectively, and the two baffle rods 11 located at the front end of the lower first fixed plate 10 are baffle rod No. 3 and baffle rod No. 4 respectively. The cable needs to bypass the upper end of baffle rod No. 1, then bypass the lower end of baffle rod No. 2, and then bypass the upper end of baffle rod No. 3, and finally bypass the lower end of baffle rod No. 4, so that the excess length of the cable is wound around the inside of the adjusting box 2 to solve the problem of cable sinking.

[0030] A support rod 14 is fixed inside the buffer box 5, and a first clamping mechanism is fixed to the upper end of the support rod 14.

A buffer mechanism is fixed on the upper side of the second clamping mechanism. The cable fixed between the first clamping mechanism and the second clamping mechanism will have more than one section in a bent state. When the installed cable is pulled, the second clamping mechanism will move under the limiting action of the second limiting rod 15, thereby pulling the bent part of the cable straight, and cooperating with the buffer mechanism, effectively buffering the external force on the cable to avoid damage to the cable.

[0033] Ceramic rings are fixed inside the first threading hole and the second threading hole. When the cable is pulled and moved, the friction between the cable and the ceramic ring is small and no friction damage is caused.

The distance between the two first fixed plates 10 can be changed by the adjusting mechanism, which is convenient for changing the distance according to the length of the cable to be wound, and the moving block 20 can only move left and right outside the screw rod 18 under the limiting action of the first fixed plate 10.

[0035] The pressing mechanism includes a moving rod 24, which is slidably connected to the side wall of the blocking rod 11. An arc-shaped pressing plate 25 is fixed to the end of the blocking rod 11. The outer wall of the blocking rod 11 is provided with a thread. The other end of the blocking rod 11 is threadedly connected with a fastening nut 26. After the cable passes around the blocking rod 11, it is pressed and fixed by the arc-shaped pressing plate 25.

[0036] The outer wall of the winding rod 13 is provided with threads, and the outer threads of the winding rod 13 are connected with a clamping nut 27. When the cable is wound around the outside of the winding rod 13, the clamping nut 27 is used to clamp the wound cable to prevent the cable from loosening.

[0037] The first clamping mechanism and the second clamping mechanism include two clamping plates 28, which are symmetrically arranged. First mounting blocks 29 are fixed on the front and rear sides of the two clamping plates 28. The two groups of first mounting blocks 29 are connected and fixed by connecting bolts. The two clamping plates 28 can be disassembled, so as to facilitate the installation of the cable between the two clamping plates 28.

The third U-shaped block 30 is fixedly connected to the upper side of the second clamping mechanism, and the fourth U-shaped block 31 is fixedly connected to the upper end of the inner wall of the buffer box 5. The interiors of the third U-shaped block 30 and the fourth U-shaped block 31 are rotatably connected to the second mounting block 32 through an axle pin. A telescopic rod 33 is fixed between the two second mounting blocks 32. The outer sleeve of the telescopic rod 33 is connected to a spring 34. Both ends of the spring 34 are fixedly connected to the side walls of the second mounting block 32. When the cable installed outside the buffer box 5 is pulled, the tension on the cable can be buffered by the buffer mechanism to avoid damage to the cable due to excessive pulling.

[0039] An exhaust hole is provided at the left end of the lower side of the regulating box 2, and a first dustproof net 35 is fixed inside the exhaust hole.

A cooling fan 37 is fixed inside the air inlet pipe 36, and a second dustproof net 38 is fixed to the lower end of the cooling fan 37. A mounting frame 39 is fixed on the upper side of the regulating box 2, and a photovoltaic panel 40 is fixed inside the mounting frame 39. The photovoltaic panel 40 is electrically connected to the cooling fan 37. Since the cables are tightly attached together inside the regulating box 2 due to winding, when the temperature is high, the cooling fan 37 can be manually controlled to work regularly to dissipate heat and cool the interior to ensure normal heat dissipation of the cables.

[0040] Working principle: When installing and setting up the cable, the cable is fixed by the first clamping mechanism and the second clamping mechanism inside the two buffer boxes 5, and the cable is ensured to pass through the inside of the regulating box 2. With continuous use, if the cable sinks, the cable can be pulled from both ends to the inside of the regulating box 2, and the cable is staggered around the outside of the baffle rod 11 at the front end of the two first fixing plates 10, and can be wound around the outside of the winding rod 13 on the side wall of the baffle rod 11, and the cable outside the baffle rod 11 is fixed by the pressing mechanism, and the cable wound outside the winding rod 13 is compressed by the clamping nut 27. When the cable is clamped and fixed by the first clamping mechanism and the second clamping mechanism inside the buffer box 5, there is a redundant part of the cable between the first clamping mechanism and the second clamping mechanism. If the cable is pulled during use, the second clamping mechanism can move with the pulling of the cable, and the second clamping mechanism can buffer the external force through the buffer mechanism. The reserved redundant cable can increase the buffering capacity and avoid pulling damage.
