Description

Technical Field

[0001] The utility model relates to the field of photovoltaic components, in particular to a photovoltaic pressing block device with a fixed bottom. Background Art

[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials. In order to prevent the photovoltaic panel assembly from shifting when installed outdoors, a block pressing device is required to press and fix the edges of the photovoltaic panel.

[0003] At present, a Chinese utility model with announcement number CN202758903U discloses a medium pressure block device for a solar photovoltaic panel, including a medium pressure block and a fixing device that fixes the solar photovoltaic panel to a U-shaped channel steel with an inwardly curled flange at the opening through the medium pressure block; the medium pressure block is provided with a clamping part that is pressed onto the upper surface of the solar photovoltaic panel, and the clamping part of the medium pressure block is arranged on both sides of the medium pressure block; the fixing device includes a lock nut that is located in the channel steel during installation and the upper surface is tightly attached to the end of the curled flange of the U-shaped channel steel, and a fastener that fastens the medium pressure block to the lock nut, and further, the fixing device also includes a protective member, including a cylindrical protective member body, the protective member body is provided with a channel and a support plate at one end; and also includes a through hole that runs through the protective member body and the support plate, and the support plate is provided with two protrusions. The medium pressure block device provided by the utility model has a simple structure, is easy to install, is firmly installed, and will not cause damage to the surface of the solar photovoltaic panel.

[0004] Although the existing pressing block device is stable to install and has high material strength, there are still other problems in the use process. For example, the existing pressing blocks are basically fixed downward from the top of the component, and it is necessary to climb up the component to fix it during installation. The workers are in high danger and are prone to step on the component, causing problems such as hidden cracks in the component. It is also inconvenient to adjust the height of the limit plate. The limit plates on both sides of the existing pressing block are formed by one-piece injection molding and cannot be adjusted during the installation process. When the photovoltaic panel components placed on both sides are of different sizes, it can only fix one side, and its practicality is low. In order to solve the above-mentioned problems, we propose a photovoltaic pressing block device with a bottom fixation. Utility Model Content

[0005] The utility model aims to provide a photovoltaic block device with a bottom fixed, which has the advantages of being convenient for workers to fix the device from the bottom and being convenient for adjusting the heights of the side panels on both sides.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a bottom-fixed photovoltaic block device, comprising a U-shaped seat, a fixing rod welded to the bottom of the U-shaped seat, a threaded sleeve fixedly sleeved on the surface of the fixing rod, a fixing piece threadedly connected to the surface of the threaded sleeve, a bottom plate welded to the bottom of the fixing rod, mounting grooves are provided on both sides of the U-shaped seat, a first limit plate and a second limit plate are respectively provided inside the two mounting grooves, the bottoms of the first limit plate and the second limit plate are rotatably connected to a threaded rod through a bearing, the other end of the threaded rod passes through and extends to the bottom of the U-shaped seat, and a threaded groove is provided at the bottom of the U-shaped seat.

It has high safety and can facilitate the adjustment of the height of the side panels on both sides. It is suitable for fixing photovoltaic components of different sizes, and has high flexibility and practicality.

[0008] The utility model is further configured as follows: the threaded sleeve and the fixing piece are both made of stainless steel.

[0012] The utility model is further configured as follows: a limiting rod is installed through the top of each of the first limiting plate and the second limiting plate, and the top and bottom of the limiting rod are welded to the inside of the installation groove.

[0013] By adopting the above technical solution, the first limit plate and the second limit plate can be limited by setting the limit rod, so as to prevent the first limit plate and the second limit plate from turning over during the process of moving up and down.

[0017] By adopting the above technical solution and providing the rubber protective pad, the photovoltaic panel can be protected to prevent the first limit plate and the second limit plate from damaging the surface of the photovoltaic panel when being pressed.

[0018] The utility model is further configured as follows: surfaces of the U-shaped seat, the first limiting plate and the second limiting plate are all coated with anti-corrosion paint.

[0019] By adopting the above technical solution and setting the anti-corrosion coating, the anti-corrosion effect on the surface of the U-shaped seat, the first limit plate and the second limit plate can be improved, thereby extending the service life of the U-shaped seat, the first limit plate and the second limit plate.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model firstly opens a guide groove corresponding to the threaded sleeve and the threaded rod on the substrate below the photovoltaic module, and then puts the device so that the threaded sleeve and the threaded rod are located in the guide groove. After the device is put in, the staff grabs the bottom plate from below to move it. After the device moves to a suitable position, the staff grabs the bottom plate with one hand to keep it stable, and grabs the fixing piece with the other hand to rotate it upward. When the fixing piece rotates upward to fit with the substrate, the threaded sleeve moves downward. When the threaded sleeve moves downward, it drives the U-shaped seat to move downward together, which is convenient for the staff to fix the device from the bottom, not only reducing the climbing burden of the staff, but also avoiding damage to the components caused by trampling, and has high safety.

[0022] 2. The utility model first uses a tool to drive the fixing cap on the left side to rotate. When the fixing cap on the left side rotates, it will drive the first limit plate to move downward through the cooperation of the threaded rod and the bearing. When the first limit plate moves downward, it will fix the photovoltaic component on one side through the cooperation of the limit rod. Then, the second limit plate is driven downward in the same way to fix the photovoltaic component on the other side. It can facilitate the adjustment of the height of the side panels on both sides and is suitable for fixing photovoltaic components of different sizes. It has high flexibility and practicality.
