[0033] See Figures 1-7 , in the figure: 1 base, 2 adjustment box, 3 first box cover, 4 fixed rod, 5 buffer box, 6 second box cover, 7 first limit rod, 8 limit block, 9 connecting rod, 10 first fixing plate, 11 blocking rod, 12 second fixing plate, 13 winding rod, 14 support rod, 15 second limit rod, 16 first vertical rod, 17 second vertical rod, 18 lead screw, 19 rotating block, 20 moving block, 21 first U-shaped block, 22 second U-shaped block, 23 adjusting plate, 24 moving rod, 25 arc-shaped pressing plate, 26 fastening nut, 27 pressing nut, 28 clamping plate, 29 first mounting block, 30 third U-shaped block, 31 fourth U-shaped block, 32 second mounting block, 33 telescopic rod, 34 spring, 35 first dust-proof net, 36 air inlet pipe, 37 cooling fan, 38 second dust-proof net, 39 mounting bracket, 40 photovoltaic panel.

[0034] See Figures 1-7 , an adjustable cable installation device, including a base 1, a support mechanism is fixed at the upper end of the base 1, an adjustment box 2 is fixed at the upper end of the support mechanism, a first box cover 3 is fixed at the front end of the adjustment box 2, symmetric fixed rods 4 are fixed on the upper side of the adjustment box 2, a buffer box 5 is fixed at the left end and the right end of the adjustment box 2 through the fixed rods 4, and a second box cover 6 is fixed at the front side of the buffer box 5;

[0035] First wire passing holes are respectively opened on the left side and the right side of the adjustment box 2, second wire passing holes are respectively opened on the left side and the right side of the two buffer boxes 5, and the cable enters the interior of the adjustment box 2 and the buffer box 5 through the first wire passing holes and the second wire passing holes.

[0036] A first limiting rod 7 is longitudinally fixed at the left end inside the adjusting box 2. Symmetrical limiting blocks 8 are slidably connected to the outside of the first limiting rod 7. Connecting rods 9 are fixed to the right sides of the two limiting blocks 8. The right ends of the two connecting rods 9 are both fixed with a first fixing plate 10. An adjusting mechanism is jointly 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 relatively long), the distance between the two first fixing plates 10 needs to be adjusted to become larger through the adjusting mechanism, 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 blocks 8. Symmetrical blocking rods 11 are fixed to the front sides of the two first fixing plates 10. Pressing mechanisms are arranged on the side walls of the two groups of symmetrical blocking rods 11. Second fixing plates 12 are fixed to the sides of the two groups of symmetrical blocking rods 11 close to each other. A winding rod 13 is fixed to the side wall of the second fixing plate 12;

[0037] The specific way of winding the cable through the cooperation of the blocking rod 11 and the winding rod 13 is as follows: The two blocking rods 11 at the front end of the upper first fixing plate 10 are respectively a first blocking rod and a second blocking rod. The two blocking rods 11 at the front end of the lower first fixing plate 10 are respectively a third blocking rod and a fourth blocking rod. The cable needs to bypass from the upper end of the first blocking rod, then bypass from the lower end of the second blocking rod, then bypass from the upper end of the third blocking rod, and finally bypass from the lower end of the fourth blocking rod, so as to wind the redundant length of the cable inside the adjusting box 2 and solve the problem of cable sinking.

[0038] A support rod 14 is fixed inside the buffer box 5. The upper end of the support rod 14 is fixed with a first clamping mechanism. A second clamping mechanism is arranged at the symmetrical position of the first clamping mechanism inside the buffer box 5. A second limiting rod 15 is fixed to the side wall of the second clamping mechanism. The second limiting rod 15 is slidably connected to the side wall of the buffer box 5. A buffer mechanism is fixed above the second clamping mechanism. There will be an extra section of the cable fixed between the first clamping mechanism and the second clamping mechanism in a bent state. When the erected cable is pulled, the second clamping mechanism will move under the limiting action of the second limiting rod 15, so as to straighten the bent part of the cable, and cooperate with the buffer mechanism to effectively buffer the external force on the cable and avoid cable damage.

[0039] The support mechanism includes a first vertical rod 16. The lower end of the first vertical rod 16 is fixedly connected to the upper side of the base 1. A second vertical rod 17 is slidably connected inside the first vertical rod 16. The upper end of the second vertical rod 17 is fixedly connected to the lower side of the adjusting box 2. The upper end on the right side of the first vertical rod 16 is threadedly connected with a first bolt. One end of the first bolt extending into the first vertical rod 16 is clamped with the second vertical rod 17. The second vertical rod 17 inside the first vertical rod 16 can be telescopically adjusted, so as to change the erection height of the cable.

[0040] The side wall of the first box cover 3 is threadedly connected with symmetric second bolts, and the first box cover 3 is fixedly connected to the front end of the adjustment box 2 through the second bolts;

[0041] The side wall of the second box cover 6 is threadedly connected with symmetric third bolts, and the second box cover 6 is fixedly connected to the front end of the buffer box 5 through the third bolts, which facilitates the disassembly of the first box cover 3 and the second box cover 6, so as to adjust the internal cables.

[0042] Ceramic rings are fixed inside both the first wire passing hole and the second wire passing hole. When the cable is pulled and moves, it ensures that the friction between the cable and the ceramic ring is small and will not be damaged by friction.

[0043] The adjustment mechanism includes a lead screw 18. The lead screw 18 is rotatably connected to the right side of the adjustment box 2 through a bearing. A rotating block 19 is fixed to the right end of the lead screw 18. A moving block 20 is threadedly connected to the rod wall of the lead screw 18. First U-shaped blocks 21 are fixed to both the upper side and the lower side of the moving block 20. Second U-shaped blocks 22 are fixed to the right sides of the two first fixing plates 10. An adjustment plate 23 is rotatably connected between the two first U-shaped blocks 21 and the two second U-shaped blocks 22 through a pin. The distance between the two first fixing plates 10 can be changed through the adjustment 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 lead screw 18 under the limiting action of the first fixing plate 10.

[0044] The pressing mechanism includes a moving rod 24. The moving rod 24 is slidably connected to the side wall of the stop rod 11. An arc-shaped pressing plate 25 is fixed to the end of the stop rod 11. Threads are provided on the outer wall of the stop rod 11, and a fastening nut 26 is threadedly connected to the other end of the stop rod 11. After the cable bypasses the stop rod 11, it is pressed and fixed by the arc-shaped pressing plate 25.

[0045] Threads are provided on the outer wall of the winding rod 13, and a pressing nut 27 is threadedly connected to the outside of the winding rod 13. After the cable is wound around the winding rod 13, the wound cable is pressed by the pressing nut 27 to prevent the cable from loosening.

[0046] The first clamping mechanism and the second clamping mechanism include two clamping plates 28. The two clamping plates 28 are symmetrically arranged. First mounting blocks 29 are fixed to both the front side and the rear side of the two clamping plates 28. The two groups of first mounting blocks 29 are connected and fixed through 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.

[0047] The buffer mechanism includes a third U-shaped block 30 and a fourth U-shaped block 31. 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.

[0048] 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. An air inlet hole is provided at the right end of the lower side of the regulating box 2, and an air inlet pipe 36 is fixed inside the air inlet 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.

[0049] 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.
