Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic module EL testing device, specifically relating to a photovoltaic module EL testing device. Background Technology

[0002] A photovoltaic module EL inspection device is a device used to detect internal defects in solar cell modules. It uses the principle of electroluminescence to capture near-infrared images of the module with a high-resolution CCD or CMOS camera to identify defects such as microcracks, fragments, poor solder joints, and broken grids.

[0003] The main components of an EL inspection device include: the core imaging system, lighting system, power supply system, control system, and a support system for fixing and supporting the inspection equipment. The EL inspection device quickly scans components in a non-contact manner, generates clear defect images, and produces reports by combining data analysis functions.

[0004] Currently, photovoltaic module EL testing devices are mostly supported by tripods for shooting, which need to be set up on flat ground. However, in order to reduce interference from sunlight, photovoltaic module EL testing is mostly carried out at night. The existing support devices for photovoltaic module EL testing equipment cannot provide warnings for uneven ground. Once the support is set up in a pit, it is easy to cause the photovoltaic module EL testing equipment to tilt or even fall over. This is not only detrimental to the testing of photovoltaic module EL, but also poses a risk of impact damage, making it inconvenient for long-term use.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a photovoltaic module EL testing device.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide a photovoltaic module EL testing device that can solve the problem that the support device of the existing photovoltaic module EL testing equipment cannot warn of uneven ground, which can easily cause the photovoltaic module EL testing equipment to tilt or fall, and there is a risk of impact damage.

[0008] To achieve the above objectives, a specific embodiment of the present invention provides a photovoltaic module EL testing device, comprising: a mounting frame, a rotation triggering mechanism, and a fixed support mechanism;

[0009] The installation rack compartment is equipped with a rotation triggering mechanism, which includes an audible and visual alarm. The lower side of the audible and visual alarm is provided with several evenly distributed lifting trigger blocks, and the side of the lifting trigger blocks near the audible and visual alarm is provided with a rotation trigger rod.

[0010] A fixed support mechanism is fixedly installed on the mounting rack.

[0011] In one or more embodiments of this utility model, the lifting trigger block is installed through the mounting frame, which facilitates the descent of the lifting trigger block, allows the lifting trigger block to move when it is not supported, and enables the lifting trigger block to drive the rotating trigger rod to rotate when it descends.

[0012] A rotary trigger bearing is installed between the lifting trigger block and the mounting frame, which reduces the friction between the lifting trigger block and the mounting frame, allowing the lifting trigger block to descend better when it is no longer supported, and allowing the rotary trigger spring to squeeze the lifting trigger block more effectively. This reduces frictional damage to the lifting trigger block and extends the service life of the lifting trigger block and the mounting frame.

[0013] The upper side of the lifting trigger block is provided with a rotating trigger spring, which can squeeze the lifting trigger block and limit its sliding, thereby reducing the probability of the lifting trigger block detaching or being lost, and improving the service life of the lifting trigger block.

[0014] In one or more embodiments of this utility model, the two ends of the rotation trigger spring are fixedly installed with the mounting frame and the lifting trigger block respectively, which improves the stability of the rotation trigger spring, reduces the probability of the rotation trigger spring detaching, and improves the service life of the lifting trigger block.

[0015] The lifting trigger block has a positioning groove that matches the rotation trigger spring. When the lifting trigger block is supported and rises, it can accommodate the rotation trigger spring, reducing the probability of the rotation trigger spring tilting and the probability of the rotation trigger spring popping out.

[0016] In one or more embodiments of this utility model, a rotating trigger connecting seat is fixedly installed on the side of the lifting trigger block near the rotating trigger rod, which can connect the lifting trigger block and the rotating trigger connecting seat, reduce the probability of the rotating trigger rod disengaging, and enable the lifting trigger block to drive the rotation of the rotating trigger rod when it rises or falls.

[0017] The rotating trigger connector is installed through the rotating trigger rod, which facilitates the connection between the lifting trigger block and the rotating trigger rod, so that the lifting of the lifting trigger block can drive the rotation of the rotating trigger rod.

[0018] The rotating trigger connector is rotatably mounted to the rotating trigger rod, allowing the rotating trigger rod to be driven, which in turn drives the rotating trigger wheel to trigger the audible and visual alarm, thus alerting the user.

[0019] In one or more embodiments of this utility model, a rotation trigger guide seat is provided on the lower side of the rotation trigger rod, which can guide the rotation trigger shaft seat, improve the stability of the rotation trigger shaft seat, allow the rotation trigger rod to be displaced when rotating, and make the rotation of the rotation trigger rod more stable.

[0020] The rotation trigger guide seat is fixedly installed with the mounting frame. A rotation trigger shaft seat is slidably installed on the rotation trigger guide seat, which can support the rotation trigger rod, improve the rotational stability of the rotation trigger rod, and allow the rotation trigger rod to rotate on the rotation trigger shaft seat.

[0021] In one or more embodiments of this utility model, the rotating trigger shaft seat is provided through the rotating trigger rod, which improves the stability of the rotating trigger rod, makes the rotation of the rotating trigger rod more controllable, and makes the rotating trigger rod better trigger the sound and light alarm.

[0022] A contact bearing is installed between the rotating trigger shaft seat and the rotating trigger rod, which reduces the friction between the rotating trigger shaft seat and the rotating trigger rod, improves the smoothness of the rotation of the rotating trigger rod, and correspondingly extends the service life of the rotating trigger rod and the rotating trigger shaft seat.

[0023] The rotating trigger rod has a rotating trigger wheel at the end away from the lifting trigger block, which can trigger the audible and visual alarm. At the same time, it can rotate on the rotating trigger rod so that the rotating trigger rod will not come into direct contact with the audible and visual alarm, thus reducing the damage to the audible and visual alarm.

[0024] In one or more embodiments of this utility model, the rotating trigger rod is provided with a positioning groove that matches the rotating trigger wheel, which reduces the collision between the rotating trigger wheel and the rotating trigger rod and reduces the probability of the rotating trigger wheel being jammed by the rotating trigger rod.

[0025] The rotating trigger rod is fixedly equipped with a rotating trigger balance shaft, which improves the stability of the rotating trigger wheel, makes the rotation of the rotating trigger wheel more controllable, allows the rotating trigger wheel to make better contact with the sound and light alarm, and reduces the damage caused to the sound and light alarm by the rotating trigger wheel. The rotating trigger balance shaft is set through the rotating trigger wheel and is rotatably installed with the rotating trigger wheel.

[0026] In one or more embodiments of this utility model, the fixed support mechanism includes multiple fixed guide chambers, which can guide the fixed guide block, thereby improving the stability of the fixed guide block and thus improving the stability of the support equipment.

[0027] A fixed guide block is slidably installed inside the fixed guide chamber, which can be used to install the support equipment and to slide and move within the fixed guide chamber, thereby improving the stability of the support equipment.

[0028] In one or more embodiments of this utility model, a guide groove matching the fixed guide block is chiseled in the fixed guide chamber, which reduces the probability of the fixed guide block tilting and correspondingly improves the stability of the fixed guide block.

[0029] In one or more embodiments of this utility model, a pair of fixed guide wheels are rotatably mounted on both sides of the fixed guide block, which facilitates the displacement of the fixed guide block, reduces the friction between the fixed guide block and the mounting frame, and improves the service life of the fixed guide block and the mounting frame. The fixed guide block is provided with a fixed groove, which facilitates the installation of the support equipment.

[0030] Compared with the prior art, the photovoltaic module EL testing device of this utility model, through the setting of the corresponding mechanism, enables the support device of the photovoltaic module EL testing equipment to warn of uneven ground, reducing the probability of the photovoltaic module EL testing equipment tilting, reducing the possibility of the photovoltaic module EL testing equipment tipping over, reducing the risk of impact damage, and making it more convenient for long-term use.

Detailed Implementation

[0043] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0044] like Figures 1 to 9 As shown, a photovoltaic module EL testing device according to one embodiment of the present invention includes: a mounting frame 1, a rotation triggering mechanism 2, and a fixed support mechanism 3.

[0045] like Figures 1 to 9 As shown, the mounting rack compartment 1 is equipped with a rotation trigger mechanism 2, which includes an audible and visual alarm 201. It can be triggered by pressing the rotation trigger wheel 210 to provide audible and visual warnings, reminding the user that the ground is uneven and reducing the risk of the support device tipping over.

[0046] The audible and visual alarm 201 has several evenly distributed lifting trigger blocks 202 on its lower side. These blocks can be squeezed by the rotating trigger spring 205, causing them to descend when they are no longer supported and are not in contact with the ground. The rotating trigger rod 203 can be rotated by rotating the trigger connecting seat 206.

[0047] In addition, a rotating trigger rod 203 is provided on the side of the lifting trigger block 202 near the sound and light alarm 201. It can be rotated by the lifting trigger block 202 to support the rotating trigger wheel 210, so that the rotating trigger wheel 210 triggers the sound and light alarm 201.

[0048] like Figures 1 to 8 As shown, the lifting trigger block 202 is installed through the mounting frame compartment 1, which facilitates the descent of the lifting trigger block 202 and allows the lifting trigger block 202 to move when it is not supported. When the lifting trigger block 202 descends, it can drive the rotating trigger rod 203 to rotate.

[0049] Among them, a rotary trigger bearing 204 is installed between the lifting trigger block 202 and the mounting frame compartment 1, which reduces the friction between the lifting trigger block 202 and the mounting frame compartment 1, so that the lifting trigger block 202 can descend better after being unsupported, and the rotary trigger spring 205 can squeeze the lifting trigger block 202 better, thereby reducing the frictional damage to the lifting trigger block 202 and the mounting frame compartment 1 and extending the service life of the lifting trigger block 202 and the mounting frame compartment 1.

[0050] In addition, a rotation trigger spring 205 is provided on the upper side of the lifting trigger block 202, which can squeeze the lifting trigger block 202 and limit the sliding of the lifting trigger block 202, thereby reducing the probability of the lifting trigger block 202 disengaging and losing, and improving the service life of the lifting trigger block 202.

[0051] like Figures 1 to 5 As shown, the two ends of the rotation trigger spring 205 are fixedly installed to the mounting frame compartment 1 and the lifting trigger block 202 respectively, which improves the stability of the rotation trigger spring 205, reduces the probability of the rotation trigger spring 205 detaching, and increases the service life of the lifting trigger block 202.

[0052] In addition, the lifting trigger block 202 has a positioning groove that matches the rotation trigger spring 205. When the lifting trigger block 202 is supported and rises, it can accommodate the rotation trigger spring 205, reducing the probability of the rotation trigger spring 205 tilting and reducing the probability of the rotation trigger spring 205 popping out.

[0053] like Figures 1 to 4As shown, a rotating trigger connecting seat 206 is fixedly installed on the side of the lifting trigger block 202 near the rotating trigger rod 203. This seat connects the lifting trigger block 202 and the rotating trigger connecting seat 206, reducing the chance of the rotating trigger rod 203 disengaging and allowing the lifting trigger block 202 to rotate as it rises or falls.

[0054] The rotating trigger connector 206 passes through the rotating trigger rod 203, which facilitates the connection between the lifting trigger block 202 and the rotating trigger rod 203, so that the lifting of the lifting trigger block 202 can drive the rotation of the rotating trigger rod 203.

[0055] In addition, the rotating trigger connector 206 and the rotating trigger rod 203 are rotatably installed so that the rotating trigger rod 203 can be driven, so that the rotating trigger rod 203 can better drive the rotating trigger wheel 210 to trigger the sound and light alarm 201, so that the sound and light alarm 201 can warn the user.

[0056] like Figures 1 to 6 As shown, a rotation trigger guide seat 207 is provided on the lower side of the rotation trigger rod 203, which can guide the rotation trigger shaft seat 208, improve the stability of the rotation trigger shaft seat 208, and allow the rotation trigger rod 203 to be displaced when rotating, making the rotation of the rotation trigger rod 203 more stable.

[0057] In addition, the rotation trigger guide seat 207 is fixedly installed with the mounting frame compartment 1, and the rotation trigger shaft seat 208 is slidably installed on the rotation trigger guide seat 207, which can support the rotation trigger rod 203, improve the rotational stability of the rotation trigger rod 203, and allow the rotation trigger rod 203 to rotate on the rotation trigger shaft seat 208.

[0058] like Figures 1 to 6 As shown, the rotating trigger shaft seat 208 is installed through the rotating trigger rod 203, which improves the stability of the rotating trigger rod 203, makes the rotation of the rotating trigger rod 203 more controllable, and makes the rotating trigger rod 203 better trigger the sound and light alarm 201.

[0059] A contact bearing 209 is installed between the rotating trigger shaft seat 208 and the rotating trigger rod 203, which reduces the friction between the rotating trigger shaft seat 208 and the rotating trigger rod 203, improves the smoothness of the rotation of the rotating trigger rod 203, and correspondingly extends the service life of the rotating trigger rod 203 and the rotating trigger shaft seat 208.

[0060] In addition, a rotating trigger wheel 210 is provided at the end of the rotating trigger rod 203 away from the lifting trigger block 202, which can trigger the audible and visual alarm 201. At the same time, it can rotate on the rotating trigger rod 203, so that the rotating trigger rod 203 will not directly contact the audible and visual alarm 201, thereby reducing the damage to the audible and visual alarm 201.

[0061] like Figures 1 to 8 As shown, the rotating trigger rod 203 has a positioning groove that matches the rotating trigger wheel 210, which reduces the collision between the rotating trigger wheel 210 and the rotating trigger rod 203, thus reducing the chance of the rotating trigger wheel 210 being jammed by the rotating trigger rod 203.

[0062] In addition, a rotating trigger balance shaft 211 is fixedly installed inside the rotating trigger rod 203, which improves the stability of the rotating trigger wheel 210, makes the rotation of the rotating trigger wheel 210 more controllable, and allows the rotating trigger wheel 210 to make better contact with the audible and visual alarm 201, reducing the damage caused by the rotating trigger wheel 210 to the audible and visual alarm 201. The rotating trigger balance shaft 211 is set through the rotating trigger wheel 210 and is rotatably installed with the rotating trigger wheel 210.

[0063] like Figures 1 to 5 As shown, a fixed support mechanism 3 is fixedly installed on the mounting frame 1. The fixed support mechanism 3 includes multiple fixed guide chambers 301, which can guide the fixed guide block 302, thereby improving the stability of the fixed guide block 302 and thus improving the stability of the support equipment.

[0064] The fixed guide block 302 is slidably installed inside the fixed guide chamber 301, which can be used to install the support equipment and can slide and move within the fixed guide chamber 301, thereby improving the stability of the support equipment.

[0065] like Figures 1 to 6 As shown, a guide groove matching the fixed guide block 302 is chiseled inside the fixed guide chamber 301, which reduces the probability of the fixed guide block 302 tilting and correspondingly improves the stability of the fixed guide block 302.

[0066] like Figures 1 to 7 As shown, a pair of fixed guide wheels 303 are rotatably mounted on both sides of the fixed guide block 302, which facilitates the displacement of the fixed guide block 302, reduces the friction between the fixed guide block 302 and the mounting frame 1, and improves the service life of the fixed guide block 302 and the mounting frame 1. The fixed guide block 302 has a fixed groove, which facilitates the installation of the support equipment.

[0067] In practical use, when the user uses the detection device at night, the installation frame 1 is placed on the ground. When the lifting trigger block 202 touches the ground, it will be affected by the weight of the installation frame 1 and will move and retract into the installation frame 1. When there are potholes on the ground, the lifting trigger block 202 will not be in contact with the ground and will be squeezed by the rotation trigger spring 205 to descend. The rotation trigger connecting seat 206 drives the rotation trigger rod 203 to rotate around the rotation trigger shaft seat 208, and drives the rotation trigger wheel 210 to contact the audible and visual alarm 201. When the audible and visual alarm 201 is pressed, it can provide an audible and visual warning to remind the user and reduce the chance of the equipment tipping over after installation.

[0068] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0069] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
