Description

Technical Field

[0001] The utility model belongs to the technical field of manufacturing solar cell modules, and specifically relates to a device for inspecting the safety distance of photovoltaic modules. Background Technique

[0002] Chinese Patent (Publication No.: CN220818836U) discloses a tooling for inspecting the safety distance of photovoltaic modules, which solves the problems that when orders are switched frequently, the safety distance changes with different plate types, and the safety distance tooling for the previous order is no longer applicable to the current order, and a new safety distance tooling needs to be made; although making a new safety distance tooling that meets the current order solves the inspection problem, if the safety distance tooling for the previous order is not taken away, it may lead to incorrect use of the safety distance tooling, resulting in a batch of components with safety distances not meeting the drawing requirements. Usually, the material for making the conventional safety distance inspection tooling is cut from the backplane, and it is severely worn during use, resulting in the accuracy not meeting the drawing requirements.

[0003] However, the above-mentioned disclosed patent still has the following technical problems:

[0004] Since the positioning bolts and gaskets can fix the position of the protruding block, thus adapting to production lines of different plate types, that is, the position of the protruding block is locked by the friction force between the bolts and gaskets and the scale plate, so as to achieve the purpose of locking the adjusting block. However, during long-term use, both the gaskets and bolts may be worn, resulting in the protruding block not being firmly fixed, and thus the purpose of locking the protruding block cannot be achieved.

[0005] Therefore, the utility model designs a device for inspecting the safety distance of photovoltaic modules to solve the technical problems existing in the prior art. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a device for inspecting the safety distance of photovoltaic modules to solve the above-mentioned technical problems.

[0007] The solution adopted by the utility model is: a device for inspecting the safety distance of photovoltaic modules, including a scale plate and a protruding block, characterized in that:

[0008] Two groups of sliding grooves are opened on the scale plate, and a protruding block is slidably connected in each of the two groups of sliding grooves. Two groups of screw rods that are threadedly connected to the protruding block are rotatably connected to the scale plate, and an adjusting handle is provided at one end of each of the two groups of screw rods.

[0009] Preferably, the sliding grooves are located at both ends of the scale plate and are symmetrically arranged with respect to the center line of the scale plate. The scale on the scale plate is marked with scale lines in units of 10 mm, and the scale numbers on both sides increase from the outside to the inside, and the numbers on the left and right sides are symmetrically arranged.

[0010] Preferably, pointers that cooperate with the engraved lines are provided at the central ends of the two sets of protruding blocks close to the scale plate.

[0011] Preferably, phosphor powder is provided on the surface of the pointer.

[0012] Preferably, the two sets of screws have opposite thread directions and are arranged on the same axis.

[0020] Regarding the foregoing and other technical contents, features and effects of the present utility model, they will be clearly presented in the following detailed description in conjunction with the Figures 1-3 reference to the embodiments. The structural contents mentioned in the following embodiments are all with reference to the accompanying drawings of the specification.

[0021] The following will describe the exemplary embodiments of the present utility model with reference to the drawings.

[0022] Embodiment 1, a photovoltaic module safety distance inspection device, including a scale plate 1 and a protruding block 2, characterized in that:

[0023] Two sets of sliding grooves 3 are formed on the scale plate 1, two sets of protruding blocks 2 are slidably connected in the two sets of sliding grooves 3, two sets of screws 4 that are threadedly connected to the protruding blocks 2 are rotatably connected to the scale plate 1, and adjusting handles 5 are provided at one ends of the two sets of screws 4;

[0024] The sliding grooves 3 are located at both ends of the scale plate 1 and are symmetrically arranged with respect to the center line of the scale plate 1. The scales on the scale plate 1 are marked in units of 10 mm. The scale numbers on both sides increase from the outside to the inside and are symmetrically arranged on the left and right sides;

[0025] Two groups of the protruding blocks 2 are provided with pointers 6 that cooperate with the scale lines near the central end of the scale plate 1;

[0026] The surface of the pointer 6 is provided with phosphor powder;

[0027] The thread directions of the two groups of screws 4 are opposite and they are arranged on the same axis;

[0028] Both the upper and lower ends of the two groups of protruding blocks 2 are provided with receiving grooves 7, and a number of auxiliary rollers 8 that cooperate with the sliding grooves 3 are rotatably connected in the receiving grooves 7;

[0029] The scale plate 1 and the protruding blocks 2 are made of stainless steel

[0030] During use, when the order is switched, the inspection distance of the tooling needs to be set. According to the requirements of the drawing, by rotating the adjusting handle 5, the screw 4 can be driven to rotate. Since the telescopic block slides in the sliding groove 3 and is threadedly connected to the screw 4, one of the protruding blocks 2 can be slid to the safe distance between the short side of the battery and the glass edge, and the other protruding block 2 can be slid to the safe distance between the long side of the battery and the glass edge by rotating the adjusting handle 5;

[0031] When the component passes through the inspection process, press the protruding block 2 of the tooling against the left vertical glass edge to check whether the battery piece coincides with the scale plate 1. If not, it means that the distance between the left end of the battery piece and the left glass edge is too large, and the distance between the right end of the battery piece and the right glass edge is too small, and adjustment is needed. When the size needs to be temporarily changed according to the requirements of different order drawings later,

[0032] By rotating the two groups of adjusting handles 5, the two groups of protruding blocks 2 can be adjusted to different positions to meet the situation of temporarily changing the size according to the requirements of different order drawings;

[0033] Due to the cooperation between the protruding block 2 and the screw 4, the screw 4 has a locking function. Therefore, the phenomenon of loosening of the protruding block 2 is not likely to occur. And when the protruding block 2 moves, the auxiliary roller 8 is provided in the receiving groove 7, which reduces the friction during movement and further improves the usability of the device;

[0034] By rotating the handle, the operation is simple, convenient to use and adjust, and the work efficiency is improved.

[0035] The above description is only for the purpose of illustrating the present utility model, and it should be understood that the present utility model is not limited to the above embodiments. All various forms of variation that conform to the idea of the present utility model are within the protection scope of the present utility model.
