DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] As shown in Figures 1 to 6 The utility model provides a photovoltaic module wiring device for photovoltaic power generation, which comprises:

[0028] The shell 1 is provided with wire inlet ports 2 on the left and right sides, and a short groove 3 is fixedly installed at the top of the shell 1.

[0029] The clamping mechanism is arranged inside the left and right sides of the shell 1.

[0030] The clamping mechanism comprises two round blocks 4, which are movably sleeved with the inside of the left and right sides of the shell 1. A square rod 5 is fixedly installed between the two round blocks 4. The outer surface of the square rod 5 movably sleeves a driving gear 6. One end of the driving gear 6 is fixedly installed with a connecting pipe 7. The outer surface of the other end of the connecting pipe 7 movably sleeves a moving plate 8. The number of the moving plate 8 is two. The opposite sides of the two moving plates 8 are fixedly installed with wire clamping blocks 9. The outer surface of the wire clamping block 9 is threadedly sleeved with a driven gear 10. The outer surface of the driven gear 10 is meshingly connected with the outer surface of the driving gear 6.

[0031] When the round block 4 rotates, the round block 4 will drive the two driving gears 6 to rotate through the square rod 5. Since the two driving gears 6 are meshingly connected with the two driven gears 10, the two driving gears 6 will drive the two driven gears 10 to rotate along the outer surface of the two wire clamping blocks 9. Since the inner part of the two driven gears 10 is threadedly sleeved with the two wire clamping blocks 9, the two driven gears 10 will move away from each other along the outer surface of the two wire clamping blocks 9 while rotating. Since the design of the two wire clamping blocks 9, when the two driven gears 10 move away from each other, the two wire clamping blocks 9 will be squeezed, and the opposite ends of the two wire clamping blocks 9 will be contracted. At this time, the cable inside the two wire clamping blocks 9 will be clamped in the contraction of the two wire clamping blocks 9.

[0032] The left end of the round block 4 is fixedly installed with a first twisting block 11, which is made of metal.

[0033] Due to the design of the first twisting block 11, the operator can drive the round block 4 to rotate by twisting the first twisting block 11.

[0034] The front end of the shell 1 is fixedly provided with a fixed block 12, and the inside of the fixed block 12 movably sleeves a screw rod 13.

[0035] The outside of the screw rod 13 movably sleeves the inside of the fixed block 12, so that the screw rod 13 can rotate in the inside of the fixed block 12.

[0036] The rear end of the screw rod 13 movably sleeves a supporting block 14, and the bottom end of the supporting block 14 is fixedly connected with the top end of the shell 1.

[0037] The supporting block 14 can support the screw rod 13, so that the screw rod 13 can rotate more stably.

[0038] The front end of the screw rod 13 is fixedly provided with a second twisting block 15, and the back surface of the second twisting block 15 movably connects with the front surface of the fixed block 12.

[0039] The second twisting block 15 can drive the screw rod 13 to rotate through the twisting of the second twisting block 15.

[0040] The outside of the screw rod 13 is movably sleeved with a movable block 16, and the bottom end of the movable block 16 movably connects with the top end of the shell 1.

[0041] The screw rod 13 movably sleeves the inside of the movable block 16, so that the movable block 16 can move forward along the top end of the shell 1 when the screw rod 13 rotates.

[0042] The inside of the left and right sides of the movable block 16 is hingedly connected with a moving rod 17, and the other end of the moving rod 17 is hingedly connected with a hinge block 18.

[0043] The movable block 16 can drive the two hinge blocks 18 to move through the two moving rods 17 when the movable block 16 moves forward.

[0044] The bottom end of the hinge block 18 is fixedly provided with a square block 19, the outside of the square block 19 movably connects with the inside of the short groove 3, and the bottom end of the square block 19 is fixedly connected with the top end of the moving plate 8.

[0045] The two square blocks 19 can move under the driving of the two hinge blocks 18 when the two hinge blocks 18 move, and the two square blocks 19 can drive the two moving plates 8 to move towards each other under the limiting of the two short grooves 3, so that the cable joints in the inside of the two moving plates 8 can be connected when the two moving plates 8 move towards each other.

[0046] The working principle and use process of the utility model are as follows:

[0047] First, the operator will place the cable inside the two moving plates 8, at this time the operator will twist the first twist block 11, because the outer surface of the round block 4 is connected with the inner surface of the outer surface of the shell 1, at this time the round block 4 will rotate along the inner surface of the shell 1 under the drive of the first twist block 11, at the same time the square rod 5 will rotate under the drive of the round block 4, at this time the square rod 5 will drive the two drive gears 6 to rotate, because the outer surface of the two connecting pipes 7 is connected with the inner surface of the two moving plates 8 respectively, at this time the two drive gears 6 will drive the two connecting pipes 7 to rotate along the inner surface of the two moving plates 8, because the outer surface of the two drive gears 6 is connected with the outer surface of the two driven gears 10 respectively, when the two drive gears 6 rotate, they will drive the two driven gears 10 to rotate, and because the inner surface of the two driven gears 10 is connected with the outer surface of the two wire clamping blocks 9 respectively, when the two driven gears 10 rotate along the outer surface of the two wire clamping blocks 9, they will move in opposite directions, because of the design of the two wire clamping blocks 9, when the two driven gears 10 move in opposite directions, they will press the outer surface of the two wire clamping blocks 9, causing the opposite ends of the two wire clamping blocks 9 to shrink inward, and then the opposite ends of the two wire clamping blocks 9 will clamp the cable during the shrinking process, thereby achieving the function of quickly clamping cables of various sizes.

[0048] Then the operator twists the second twist block 15, at this time the screw rod 13 will rotate along the inner surface of the fixed block 12 under the drive of the second twist block 15, because the outer surface of the screw rod 13 is connected with the inner surface of the movable block 16, when the screw rod 13 rotates, it will drive the movable block 16 to move, because the bottom end of the movable block 16 is connected with the top end of the shell 1, at this time the movable block 16 will move forward along the top end of the shell 1, at the same time the movable block 16 will drive the two moving rods 17 to move, at this time the other end of the two moving rods 17 will pull the two hinge blocks 18, causing the two hinge blocks 18 to drive the two square blocks 19 to move, because of the design of the two short grooves 3, the movement of the two square blocks 19 will be limited, so that they can only move left and right, at this time the two square blocks 19 will move towards each other along the inner surface of the two short grooves 3 under the drive of the two hinge blocks 18, at this time the two moving plates 8 will move towards each other under the drive of the two square blocks 19, then the two square blocks 19 will drive the two drive gears 6 to move towards each other along the outer surface of the square rod 5 through the two connecting pipes 7, at the same time the two wire clamping blocks 9 will also move towards each other as a whole under the drive of the two moving plates 8, at this time the cable joints inside the two moving plates 8 will be connected during the movement towards each other, thereby achieving the function of conveniently connecting the cables.
