Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic grid-connected cabinets, and in particular to a photovoltaic grid-connected cabinet that is easy to install. Background Art

[0002] As is well known, a photovoltaic grid-connected cabinet (PV grid-connected cabinet) is a device used to convert the DC power generated by a photovoltaic power generation system into AC power and inject it into the power system through the grid connection point. It serves as the "brain" of the PV power generation system, monitoring, regulating, and protecting the PV power and ensuring precise matching with the power system. Traditional PV grid-connected cabinets are generally installed on the ground using a mounting base. However, due to the complex installation environment of some PV grid-connected cabinets, PV grid-connected cabinets are forced to be installed on the wall.

[0003] For example, the patent with authorization announcement number CN220156013U and announcement date 2023-12-08, entitled "A photovoltaic grid-connected cabinet that is easy to install", includes a cabinet body, a cabinet door is rotatably connected to the surface of the cabinet body, a handle is fixedly installed on the surface of the cabinet door, a vent is provided on the surface of the cabinet body, a mounting hole is provided on the inner surface of the cabinet body, a mounting seat is fixedly installed on the inner surface of the cabinet body, and a threaded rod is provided on the inner surface of the mounting seat. By setting the mounting holes, mounting seats, limit blocks and threaded rods and other structures, four groups of mounting holes are designed on the surface of the cabinet body, and mounting seats are designed on the surfaces of these four groups of mounting holes. Since the size of the thread on the inner surface of the mounting seat is the same as the size of the thread on the threaded rod, the user can fix the cabinet body to the wall by screwing the threaded rod into the mounting seat. Such a design can make the installation of electrical equipment by workers more labor-saving and convenient.

[0004] There are certain problems in the above description. For example, when the threaded rod is fixed with the wall mounting hole, due to the small aperture of the wall mounting hole, the accuracy of aligning and fixing the threaded rod with the wall mounting hole one by one is difficult to control during the installation process. It is necessary to repeatedly lift the cabinet for alignment operations, which makes installation inconvenient. Summary of the Invention

[0005] The purpose of the present invention is to provide a photovoltaic grid-connected cabinet that is easy to install to solve the above-mentioned problems.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A photovoltaic grid-connected cabinet that is easy to install includes a cabinet body and multiple mounting holes 1 set on a wall. The cabinet body is provided with multiple mounting holes 2, each of the mounting holes 2 is correspondingly connected to each mounting hole 1 through a threaded bolt. The cabinet body is provided with an adjustment mechanism, and the adjustment mechanism includes a threaded sleeve.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, this embodiment provides a photovoltaic grid-connected cabinet that is easy to install, including a cabinet body 1 and a plurality of mounting holes 2 set on the wall, the cabinet body 1 is provided with a plurality of mounting holes 3, each of the mounting holes 2 3 is connected to each mounting hole 2 by a threaded bolt 4, and the cabinet body 1 is provided with an adjustment mechanism, the adjustment mechanism includes a threaded sleeve 5, and the threaded sleeve 5 is driven to reciprocate to align and fix with the mounting hole 2 and the mounting hole 3 one by one.

[0027] Specifically, the cabinet 1 is arranged vertically, and a cavity is provided inside the cabinet 1. The cavity is mainly used to install some photovoltaic electrical equipment (not shown in the figure). A cabinet door (not shown in the figure) is provided on one side of the cabinet 1, and the cabinet door is used to protect the photovoltaic electrical equipment inside the cabinet 1 to avoid being affected by external dust and other impurities, thereby affecting the normal operation of the internal photovoltaic electrical equipment. The cabinet 1 is set on the wall. The specific connection method in this embodiment is a threaded connection, that is, the cabinet 1 is fixedly installed on the wall by threaded connection of the threaded bolt 4 with the mounting hole 1 2 and the mounting hole 2 3. Among them, in this embodiment, the number of mounting holes 1 2 is preferably four, and they are respectively provided on the side walls inside the cabinet 1. In this way, the number and position of the mounting holes 1 2 and the mounting holes 2 3 are one-to-one corresponding. The apertures of the mounting holes 1 2 and the mounting holes 2 3 are the same, and both are provided with threads that are compatible with the threaded bolt 4. The above are all existing technologies and will not be repeated.

[0028] In this embodiment, when the threaded rod is threadedly fixed to the wall mounting hole, due to the small diameter of the wall mounting hole, the accuracy of aligning and fixing the threaded rod with the wall mounting hole 1 is difficult to control during the installation process, and the cabinet 1 needs to be repeatedly lifted for alignment operations, which makes installation inconvenient.

[0029] Based on this, it is necessary to reduce the operation of repeatedly lifting the cabinet 1 for alignment during the installation process. Therefore, the innovation of this embodiment is that an adjustment mechanism is provided on the cabinet 1, and the adjustment mechanism includes a threaded sleeve 5. The threaded sleeve 5 is driven to reciprocate so as to be aligned and fixed one by one with the mounting hole 1 2 and the mounting hole 2 3. Specifically, the threaded sleeve 5 is preferably driven by a reciprocating rotation unit such as an electric screw cutter (not shown in the figure), that is, the electric screw cutter is used to push the threaded bolt 4 to perform a rotational movement, wherein the working direction of the threaded bolt 4 is in the horizontal direction to achieve threaded fixation, and the threaded bolt 4 is clamped on the electric screw cutter through a nut (not shown in the figure). By starting the electric screw cutter, the nut and the threaded bolt 4 are driven to rotate synchronously to enter the interior of the mounting hole 2 3. The above is the existing technology and will not be repeated. The adjustment mechanism also includes a plurality of extrusion springs 6, which are arranged between the threaded sleeve 5 and the second mounting hole 3, and the outer surface of the threaded sleeve 5 is fixedly connected to a limit ring 7, which is slidably connected to the inner wall of the cabinet 1, and the limit ring 7 is used to limit the threaded sleeve 5 so that it slides on the inner wall of the cabinet 1, that is, the threaded bolt 4 can maintain a horizontal state and be threadedly connected to the threaded sleeve 5 to smoothly enter the interior of the threaded sleeve 5. A guide groove 8 is provided on the mounting hole 2. The guide groove 8 is used to guide the threaded bolt 4, and the shape of the guide groove 8 is trumpet-shaped, and the end with a smaller opening is connected to the mounting hole 2 to increase the aperture of the mounting hole 2. One end of the threaded bolt 4 is provided with a chamfer, and the chamfer is adapted to the guide groove 8. When the chamfer abuts against the guide groove 8, the threaded bolt 4 slides into the interior of the mounting hole 2 for threaded connection through the guidance of the guide groove 8, so that the mounting hole 2 and the mounting hole 2 3 are on the same horizontal line, so as to achieve fixation between the cabinet 1 and the wall. It should be noted that the purpose of providing the extrusion spring 6 is that when the mounting hole 1 2 and the mounting hole 2 3 are not in an aligned state, the threaded bolt 4 is guided by the guide groove 8 to slide into the mounting hole 1 2, thereby fixing the cabinet 1. At this time, the position of the mounting hole 2 3 is changed by squeezing the extrusion spring 6, so that the mounting hole 1 2 and the mounting hole 2 3 are in an aligned state. At the same time, after the cabinet 1 is installed, if some wires need to be arranged outside the cabinet 1, when the position of the wires is relatively limited, the cabinet 1 is pushed at this time to squeeze the extrusion spring 6 inside the cabinet 1, so that the cabinet 1 moves as a whole, so as to realize the movement of the cabinet 1, thereby facilitating the adjustment and arrangement of the position of the wires.

[0030] Specifically, during installation, the cabinet body 1 is fitted against the wall, and the cabinet body 1 is lifted so that the mounting hole 1 2 and the mounting hole 2 3 are on the same horizontal line, that is, aligned. When the mounting hole 1 2 and the mounting hole 2 3 are in a non-aligned state, that is, there is a slight deviation, in order to enable the threaded bolt 4 to enter the interior of the wall mounting hole 2 3, the threaded bolt 4 is driven into the threaded sleeve 5 by starting the external electric screw cutter, and continuously extends into the threaded sleeve 5 and abuts against the guide groove 8. The threaded bolt 4 continues to rotate and enters the mounting hole 1 2 for threaded connection. In this process, the extrusion spring 6 is squeezed and deformed, thereby satisfying the threaded bolt 4 to fix the cabinet body 1.

[0031] The beneficial effects of this embodiment are as follows: by providing an adjustment mechanism, the position of the threaded sleeve 5 can be flexibly adjusted, so that the threaded bolt 4 abuts against the guide groove 8 on the mounting hole 1 2, and the threaded bolt 4 is passively adjusted in position, so that the mounting hole 1 2 on the cabinet 1 and the mounting hole 2 3 on the wall are aligned, thereby completing the fixation of the position of the cabinet 1 without the need for multiple alignment operations, thereby facilitating the installation operation.

[0032] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
