Description

Technical Field

[0001] The invention relates to the field of photovoltaic assembly clamping, and in particular to a clamping device for photovoltaic panel detection. Background Art

[0002] After production, photovoltaic modules need to be inspected to ensure that there are no quality problems. This requires a special placement table for placement. The disadvantage of the placement table is that it needs to be turned over when inspecting the other side. Because the photovoltaic modules themselves are relatively heavy, it is not convenient to operate when turning them over, especially those that need to be inspected back and forth on both sides. Some problems arise after outdoor use and need to be brought back for inspection. Therefore, how to facilitate the flipping inspection of photovoltaic modules is an urgent problem that technicians in this field need to solve. Summary of the invention

[0003] The object of the present invention is to provide a clamping device for photovoltaic panel detection to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a clamping device for photovoltaic panel detection, comprising a base plate and a support tube with a square inner cavity cross-section installed on the base plate, a "U"-shaped lower support plate supporting the photovoltaic assembly from the lower end is installed on the lower side of the middle part of the support tube, and an inverted "U"-shaped upper support plate clamping the photovoltaic assembly from the upper side is installed on the upper end of the support tube, and also includes a telescopic mechanism arranged between the upper support plate and the support tube and a rotating mechanism arranged between the support tube and the base plate, so as to facilitate the detection of the rear position, so that the detection personnel do not need to go around to the rear side. The upper support plate is moved up and down by the telescopic mechanism, thereby fixing the photovoltaic assembly. Here, the upper support plate and the lower support plate are both horizontal strips, corresponding to the upper and lower sides of the photovoltaic assembly.

[0005] Preferably, the telescopic mechanism includes a telescopic rod inserted into the support tube, and the upper end of the telescopic rod is fixedly connected to the upper support plate. The telescopic rod corresponds to the inner cavity cross-section of the support tube and can move up and down.

[0006] Preferably, a friction block is installed at the lower end of the telescopic rod to increase friction and prevent random sliding, and the friction block is pressed against the inner wall of the support tube. In this way, the upper support plate can be fixed at a desired position to prevent the photovoltaic assembly from being directly pressed down without lifting or holding it first.

[0007] Preferably, the rotating mechanism includes a support tube with an open upper end fixed on the bottom plate and a rotating body inserted inwardly into the support tube, the lower end of the support tube is fixed on the rotating body, and the rotating body can rotate around the support tube.

[0008] Preferably, a friction mechanism is also provided between the rotating body and the supporting cylinder to limit the rotation speed. When the rotation speed is too fast, the friction force is used to slow down the rotation speed in order to ensure that the photovoltaic module will not tilt or fall out.

[0009] Preferably, the friction mechanism includes guide grooves arranged at equal intervals in the circumferential direction of the rotating body and a matching counterweight block inserted in the guide groove, and the end of the counterweight block is against the inner wall of the support tube to generate friction. When the rotating body rotates, the counterweight block can use centrifugal force to increase the squeezing force on the support tube. The middle part of the counterweight block is provided with an air hole to maintain pressure balance. When the speed is too fast, the centrifugal force is relatively large, and the counterweight block can be pressed against the inner wall of the support tube to increase the friction and slow down the speed. The greater the rotation speed, the greater the friction, and the more obvious the deceleration effect.

[0010] Preferably, the outer end of the counterweight block is inclined downward, so that initially, friction can be generated by utilizing the gravity of the counterweight block.

[0011] Preferably, the end of the counterweight block is in an arc shape that fits the support tube, thereby increasing the contact area and achieving a better friction effect. A rubber pad for increasing friction is fixed to the end of the counterweight block, and an air vent runs through the rubber pad.

[0012] Preferably, the rotating body is in the shape of a shell with a hollow interior to reduce weight, with an opening at the lower end, and the guide groove is formed by an inner wall that is recessed inwards.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Put the photovoltaic module on the lower support plate, and then fix it by clamping it on the upper support plate. It is simple and convenient. Pull the photovoltaic module, and the rotating body can rotate around the support tube, so there is no need for the staff to go around to the back side, which is more convenient.

[0015] 2. The setting of the counterweight can prevent the rotation speed from being too fast. When the speed is fast, the friction is increased through centrifugal force, which slows down the speed and is safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 The present invention provides a technical solution for a clamping device for photovoltaic panel detection: a clamping device for photovoltaic panel detection, comprising a base plate 1 and a support tube 2 with a square inner cross-section installed on the base plate 1, a "U"-shaped lower support plate 3 supporting the photovoltaic module from the lower end is installed on the lower side of the middle part of the support tube 2, and an inverted "U"-shaped upper support plate 4 clamping the photovoltaic module from the upper side is installed on the upper end of the support tube 2, and also includes a telescopic mechanism arranged between the upper support plate 4 and the support tube 2 and a rotating mechanism arranged between the support tube 2 and the base plate 1, which is convenient for detecting the rear position, so that the detection personnel do not need to go around to the rear side. The upper support plate 4 is moved up and down by the telescopic mechanism, thereby fixing the photovoltaic module. Here, the upper support plate 4 and the lower support plate 3 are both horizontal strips, corresponding to the upper and lower sides of the photovoltaic module.

[0024] The telescopic mechanism includes a telescopic rod 5 inserted into the support tube 2, and the upper end of the telescopic rod 5 is fixedly connected to the upper support plate 4. The telescopic rod 5 corresponds to the inner cavity cross section of the support tube 2 and can move up and down. The lower end of the telescopic rod 5 is installed with a friction block 6 that increases friction to prevent random sliding, and the friction block 6 is tightly pressed against the inner wall of the support tube 2. In this way, the upper support plate 4 can be fixed at a desired position to prevent the photovoltaic module from being directly pressed down without having to lift it up or hold it first.

[0025] The rotating mechanism includes a support tube 7 with an open upper end fixed on the base plate 1 and a rotating body 8 inserted inwardly into the support tube 7 to adapt to the support tube 7. The lower end of the support tube 2 is fixed on the rotating body 8, and the rotating body 8 can rotate around the support tube 7.

[0026] It also includes a friction mechanism arranged between the rotating body 8 and the support tube 7 to limit the rotation speed. When the rotation speed is too fast, in order to ensure that the photovoltaic module will not tilt or fall out, the friction force is used to slow down. The friction mechanism includes a guide groove 9 arranged at equal intervals on the circumference of the rotating body 8 and a counterweight 10 inserted in the guide groove 9, and the end of the counterweight 10 is against the inner wall of the support tube 7 to generate friction. When the rotating body 8 rotates, the counterweight 10 can use centrifugal force to increase the squeezing force on the support tube 7. The middle part of the counterweight 10 is provided with a vent 11 to maintain pressure balance. When the speed is too fast, the centrifugal force is relatively large, and the counterweight 10 can be pressed against the inner wall of the support tube 7, increasing the friction force and slowing down the speed. The greater the rotation speed, the greater the friction force, and the more obvious the deceleration effect. The rotating body 8 is in the shape of a hollow shell inside, which reduces the weight, and the lower end is open. The guide groove 9 is formed by the inner wall being concave inward. Here, the support tube 7 can be cylindrical, and the shape of the rotating body 8 corresponds. The outer end of the counterweight 10 is tilted downward, so that initially, friction can be generated by the gravity of the counterweight 10. The end of the counterweight 10 is in an arc shape that fits the support tube 7, increasing the contact area and achieving a better friction effect. A rubber pad 12 for increasing friction is fixed to the end of the counterweight 10, and the air vent 11 passes through the rubber pad 12.

[0027] In addition, the rubber pad 12 can also be configured as a hollow capsule, so that when the counterweight 10 rotates faster, the pressure increases, the hardness of the rubber pad 12 increases, the friction coefficient increases, the friction force increases, and the deceleration effect is improved.

[0028] like Figure 5 As shown, as a second embodiment, different from the above embodiments, the support tube 7 can also be in the shape of an inverted cone, the shape of the rotating body 8 corresponds, and a downward extrusion gap is left between the lower end of the rotating body 8 and the bottom plate 1, so that the rotating body 8 will give an extrusion force to the inner wall of the support tube 7. When there is no photovoltaic component, the upper part is relatively light, which is convenient for rotation to adjust the angle and for placing the photovoltaic component. After placing it, the gravity of the photovoltaic component will be converted into the extrusion force and friction force of the rotating body 8 on the support tube 7, avoiding random shaking and being safer.

[0029] Working principle: The photovoltaic module is placed on the lower support plate 3, and then clamped and fixed by the upper support plate 4 on the upper side. It is simple and convenient. Pull the photovoltaic module, and the rotating body 8 can rotate around the support tube 7, so that the staff does not need to go around the back side, which is more convenient. The setting of the counterweight block 10 can prevent the rotation speed from being too fast. When the speed is fast, the friction force is increased by centrifugal force, slowing down the speed, which is safer.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
