Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic module trays, and particularly relates to a tray device for photovoltaic modules. Background Technique

[0002] Photovoltaic modules are the core part of a solar power generation system, usually composed of multiple solar cells connected in series and parallel in a certain way. The main function of photovoltaic modules is to convert solar energy into electrical energy. Their performance and quality directly affect the efficiency and stability of the entire photovoltaic power generation system. High-quality photovoltaic modules have high photoelectric conversion efficiency, good weather resistance, and long service life.

[0003] For example, the Chinese patent with the publication number CN216084820U discloses a tray device for photovoltaic modules, which includes a tray chassis and a tray bracket. The tray chassis and the tray bracket are integrally formed. The inclination angle between the tray bracket and the tray chassis is 65°. There are convex tooth parts on the tray chassis. The convex tooth parts include a first tooth surface and a second tooth surface. The first tooth surface is perpendicular to the tray bracket, and the second tooth surface is perpendicular to the first tooth surface. There are several groups of convex tooth parts. The tray device also includes a limiting device. There is a chute on the tray chassis. The limiting device includes a limiting block and a spring. One end of the limiting block abuts against the photovoltaic module, and one end of the limiting block is connected to the spring. The photovoltaic modules are placed horizontally on the bottom tray. The glass surface of the first photovoltaic module abuts against the tray bracket, and the rest of the photovoltaic modules are stacked in sequence. This solution avoids the problem that the simple stacking of photovoltaic modules easily causes them to slide.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use. For example, when transporting photovoltaic modules, only springs and limiting blocks are used to fix several photovoltaic modules, and there is no protection on the periphery of the photovoltaic modules. During the movement of the photovoltaic modules, the photovoltaic modules are prone to collision and falling, resulting in damage to the photovoltaic modules. In addition, the handle of this device is fixed. When used by a person with a relatively tall height, the person needs to bend down for operation, and bending down for a long time is likely to cause physical discomfort. In view of this, we propose a tray device for photovoltaic modules. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a tray device for photovoltaic modules to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a tray device for photovoltaic modules, including:

[0008] A tray, on the top of which there are several placing grooves. A first rubber pad is fixedly installed on the inner wall of the placing groove. A rectangular groove is opened at the bottom of the tray and within several placing grooves. An extrusion plate is slidably installed in the rectangular groove. The two ends of the extrusion plate respectively penetrate through both sides of the rectangular groove and extend to the outside. A second rubber pad is fixedly installed on the top of the extrusion plate. Several first springs fixed to the bottom of the rectangular groove are fixedly installed on the bottom of the extrusion plate;

[0009] A limiting component, which is located within the tray and is used to limit the extrusion plate;

[0010] A rotating rod, which is rotatably installed on one side of the tray. A groove is opened within the rotating rod, and a telescopic rod is slidably installed in the groove;

[0011] A fixing component, which is located on the rotating rod and is used to fix the telescopic rod;

[0012] A protective cover, which is inserted and installed on the top of the tray. Universal wheels are fixedly installed at the four corners of the bottom of the tray.

[0013] In this technical solution, by setting the extrusion plate, pressing down the extrusion plate causes the extrusion plate to move downward in the rectangular groove. The downward movement of the extrusion plate will squeeze several first springs to contract. Subsequently, through the set limiting component, the limiting component can limit the extrusion plate. Then, the user can pull out the protective cover from the tray and place several photovoltaic components into several placing grooves respectively until the photovoltaic components completely enter the placing grooves. At this time, the bottom of the photovoltaic components will abut against the second rubber pad. Then, the user can insert the protective cover back onto the tray. Under the protection of the second rubber pad and the first rubber pad, it can be ensured that the photovoltaic components will not be damaged during transportation;

[0014] Through the set fixing component, the fixing component can release the fixation of the telescopic rod. The user can pull the telescopic rod according to their own height, causing the telescopic rod to slide within the groove until the telescopic rod is adjusted to a suitable position. Then, the fixing component can fix the telescopic rod. Subsequently, the user can pull the telescopic rod and drive the tray to move. At the same time, the four universal wheels will rotate, ensuring that the length of the telescopic rod can be freely adjusted according to the user's height, thereby facilitating the user to pull the tray. When pulling the tray, there is no need for the user to bend down.

[0015] In the above technical solution, further, the limiting component includes:

[0016] A rectangular block, which is fixedly installed at the bottom of the extrusion plate. A limiting groove is formed on one side of the rectangular block. A plugging groove is formed at the bottom of the rectangular groove and directly below the rectangular block. A sliding groove is formed in the tray and on one side of the plugging groove. A limiting block is slidably installed in the sliding groove. One end of the limiting block penetrates through one side of the sliding groove and extends into the plugging groove. The other end of the limiting block is fixedly installed with a pull rod in the sliding groove. One end of the pull rod penetrates through the other side of the sliding groove and extends to the outside. The other end of the limiting block is fixedly installed with two springs II that are fixed to the inner wall of the sliding groove on both sides of the pull rod.

[0017] In this technical solution, when pressing down the extrusion plate, the extrusion plate moves downward in the rectangular groove. The downward movement of the extrusion plate will squeeze a number of springs I to contract. At the same time, the downward movement of the extrusion plate will also drive the rectangular block to move downward until the rectangular block is inserted into the plugging groove. At the same time, the downward movement of the rectangular block will also squeeze the inclined surface of the limiting block, causing the limiting block to move in the sliding groove. At the same time, the movement of the limiting block will squeeze two springs II to contract until one end of the limiting block completely enters the sliding groove. When the rectangular block completely enters the plugging groove, under the action of the rebounding force of the two springs II, the two springs II will squeeze the limiting block, causing one end of the limiting block to be inserted into the limiting groove. At this time, the limiting block can limit the rectangular block. Then, the operator can pull out the protective cover from the tray and place a number of photovoltaic modules into a number of placement grooves respectively until the photovoltaic modules completely enter the placement grooves. At this time, the bottom of the photovoltaic modules will abut against the rubber pad II. Then, the operator can insert the protective cover back onto the tray. Under the protection of the rubber pad II and the rubber pad I, it can be ensured that the photovoltaic modules will not be damaged during transportation.

[0018] In the above technical solution, further, the rectangular block is in plugging fit with the plugging groove, one end of the limiting block is in plugging fit with the limiting groove, and the pull rod is slidably connected with the sliding groove and the tray.

[0019] In this technical solution, it is ensured that the rectangular block can be inserted into the plugging groove, one end of the limiting block can be inserted into the limiting groove, and the pull rod can slide normally in the sliding groove and the tray.

[0020] In the above technical solution, further, the fixing assembly includes:

[0021] A threaded rod, which is threadedly installed on one side of the rotating rod. One end of the threaded rod is fixedly installed with a rubber pad III, and one side of the rubber pad III abuts against the telescopic rod.

[0022] In this technical solution, the user can rotate the threaded rod. Under the action of the thread, the threaded rod will move on the rotating rod until the rubber pad III moves away from the telescopic rod. At this time, the rubber pad III can release the fixation of the telescopic rod. The user can pull the telescopic rod according to their own height, so that the telescopic rod slides in the groove. Until the telescopic rod is adjusted to the appropriate position, the threaded rod can be rotated again. Under the action of the thread, the threaded rod will move on the rotating rod until the rubber pad III abuts against the telescopic rod. At this time, the rubber pad III will deform. Under the action of the friction force of the rubber pad III, the telescopic rod can be fixed. Then the user can pull the telescopic rod and drive the tray to move. At the same time, the four universal wheels will rotate to ensure that the length of the telescopic rod can be freely adjusted according to the user's height, so as to facilitate the user to pull the tray. When pulling the tray, there is no need for the user to bend down.

[0023] In the above technical solution, further, one end of the limiting block is of an inclined structure.

[0024] In this technical solution, it is ensured that when the rectangular block moves downward, it can squeeze the limiting block to move.

[0025] In the above technical solution, further, several of the placement grooves are arranged in a matrix.

[0026] In this technical solution, the structures of several placement grooves are ensured to be stable.

[0027] In the above technical solution, further, several of the first springs are arranged in a matrix.

[0028] In this technical solution, the forces on several of the first springs are ensured to be uniform.

[0029] The beneficial effects of the present utility model are:

[0030] 1. For the tray device of the photovoltaic module, by setting the pressing plate, pressing down the pressing plate makes the pressing plate move downward in the rectangular groove. The downward movement of the pressing plate will squeeze several of the first springs to contract. Then, through the set limiting component, the limiting component can limit the pressing plate. Then the user can pull out the protection cover from the tray and place several photovoltaic modules into several placement grooves respectively until the photovoltaic modules completely enter the placement grooves. At this time, the bottom of the photovoltaic module will abut against the rubber pad II. Then the user can insert the protection cover back onto the tray. Under the protection of the rubber pad II and the rubber pad I, it can be ensured that the photovoltaic module will not be damaged during transportation.

[0031] 2. The tray device of the photovoltaic module, through the set fixing component, can release the fixation of the telescopic rod. Personnel can pull the telescopic rod according to their own height, so that the telescopic rod slides in the groove. When the telescopic rod is adjusted to a suitable position, the fixing component can fix the telescopic rod. Subsequently, personnel can pull the telescopic rod and drive the tray to move. At the same time, the four universal wheels will rotate to ensure that the length of the telescopic rod can be freely adjusted according to the height of the personnel, thus facilitating personnel to pull the tray. When pulling the tray, it is not necessary for personnel to bend down. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] Working principle: When in use, the operator can first press down the extrusion plate 5, causing the extrusion plate 5 to move downward within the rectangular groove 4. The downward movement of the extrusion plate 5 will compress a number of first springs 7, and at the same time, the downward movement of the extrusion plate 5 will also drive the rectangular block 9 to move downward until the rectangular block 9 is inserted into the insertion slot 8. At the same time, the downward movement of the rectangular block 9 will also compress the inclined surface of the limit block 12, causing the limit block 12 to move within the sliding slot 11. At the same time, the movement of the limit block 12 will compress two second springs 14 until one end of the limit block 12 completely enters the sliding slot 11. When the rectangular block 9 completely enters the insertion slot 8, under the action of the elastic force of the two second springs 14, the two second springs 14 will squeeze the limit block 12, causing one end of the limit block 12 to be inserted into the limit slot 10. At this time, the limit block 12 can limit the rectangular block 9. Subsequently, the operator can pull out the protective cover 21 from the tray 1 and place a number of photovoltaic modules into a number of placement slots 2 respectively until the photovoltaic modules completely enter the placement slots 2. At this time, the bottom of the photovoltaic module will abut against the second rubber pad 6. Then the operator can insert the protective cover 21 back onto the tray 1. Under the protection of the second rubber pad 6 and the first rubber pad 3, it can be ensured that the photovoltaic modules will not be damaged during transportation;

[0077] Subsequently, the operator can rotate the threaded rod 18. Under the action of the thread, the threaded rod 18 will move on the rotating rod 15 until the third rubber pad 19 moves away from the telescopic rod 17. At this time, the third rubber pad 19 can release the fixation of the telescopic rod 17. The operator can pull the telescopic rod 17 according to his own height, causing the telescopic rod 17 to slide within the groove 16 until the telescopic rod 17 is adjusted to a suitable position. Then the operator can rotate the threaded rod 18 again. Under the action of the thread, the threaded rod 18 will move on the rotating rod 15 until the third rubber pad 19 abuts against the telescopic rod 17. At this time, the third rubber pad 19 will deform. Under the action of the friction force of the third rubber pad 19, the telescopic rod 17 can be fixed. Subsequently, the operator can pull the telescopic rod 17 and drive the tray 1 to move. At the same time, the four universal wheels 20 will rotate to ensure that the length of the telescopic rod 17 can be freely adjusted according to the operator's height, thereby facilitating the operator to pull the tray 1. When pulling the tray 1, there is no need for the operator to bend down;

[0078] When it is necessary to take out several photovoltaic modules, the personnel can first pull out the protective cover 21, and then pull the pull rod 13 outwards. The pull rod 13 will drive the limit block 12 to move. The movement of the limit block 12 will squeeze the two second springs 14 to contract. Until one end of the limit block 12 moves out of the limit groove 10, at this time, the limit block 12 can release the limit on the rectangular block 9. At this time, under the action of the elastic force of several first springs 7, the several first springs 7 will squeeze the extrusion plate 5, so that the extrusion plate 5 moves upward. The upward movement of the extrusion plate 5 will squeeze several photovoltaic modules through the second rubber pad 6, so that several photovoltaic modules move upward until the tops of several photovoltaic modules move above several placement grooves 2. At this time, the personnel can take out several photovoltaic modules to ensure that it is convenient for the personnel to take out several photovoltaic modules.
