Description

Technical Field

[0001] The utility model relates to the technical field of grid-connected boxes, in particular to a distributed photovoltaic power generation grid-connected box. Background Art

[0002] Distributed photovoltaic power generation specifically refers to photovoltaic power generation facilities that are built near the user's site, and whose operating mode is that the user generates electricity for their own use and the excess electricity is connected to the grid, and the distribution system is balanced and regulated. When the excess electricity is connected to the grid, a grid connection box is required (the grid connection box exists in the photovoltaic system as the total outlet of the photovoltaic power station. It is a distribution device that connects the photovoltaic power station and the power grid. Its main function is to serve as the dividing point between the photovoltaic power generation system and the power grid).

[0003] The grid connection box is mainly installed on the ground or on the wall, and in order to prevent unauthorized personnel from opening the grid connection box, the grid connection box is usually provided with a door lock, and the existing door lock lacks a protective mechanism. When it rains for a long time, the lock hole is easily corroded by water, causing the grid connection box to be unable to be opened. At the same time, when the electrical components in the existing grid connection box are fixedly installed inside the grid connection box, when the electrical components fail, the inside of the grid connection box is blocked for maintenance sight and light, which is inconvenient for maintenance operations, especially when the grid connection box is large and has many electrical components. Therefore, a technical measure is proposed to solve the problem that the existing door lock lacks a protective mechanism, when it rains for a long time, the lock hole is easily corroded by water, causing the grid connection box to be unable to be opened, and when the electrical components in the grid box are fixedly installed inside the grid connection box, when the electrical components fail, the inside of the grid connection box is blocked for maintenance sight and light, which is inconvenient for maintenance operations. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies in the prior art and provide a distributed photovoltaic power generation grid-connected box. Through the provision of a protective component, rainwater can be blocked from entering the door lock when it rains, thereby preventing rainwater from rusting the door lock and causing the door lock to be unable to be opened, thereby increasing the service life of the door lock. Through the provision of a shifting component, the mounting plate can be conveniently shifted to the box door, so that the electrical components are also shifted to the box door. When the electrical components are inspected and repaired, the box body will not block the operator's sight and light, thereby facilitating the inspection and repair work. This solves the problem that some door locks lack a protective mechanism, and when it rains for a long time, the lock hole is easily corroded by water, causing the grid-connected box to be unable to be opened. When the electrical components in the grid-connected box are fixedly installed inside the grid-connected box, when the electrical components fail, the inside of the grid-connected box blocks the inspection sight and light, thereby making it inconvenient for the inspection and repair work.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: it includes a box body, on which a box door is rotatably installed, a door lock is provided in the middle position of the box door, a protective component is installed at the door lock of the box door, two groups of symmetrically distributed sliding rods are installed at the lower part of the inside of the box body, and the sliding rods are slidably connected with a shifting component, and a limiting groove is provided on the sliding rod. Thanks to the setting of the protective component, rainwater can be blocked from entering the door lock when it rains, thereby preventing rainwater from rusting the door lock and causing the door lock to be unable to be opened, thereby improving the service life of the door lock. At the same time, thanks to the setting of the shifting component, it is convenient to shift the mounting plate to the box door, so that the electrical components are also shifted to the box door. When the electrical components are inspected and repaired, the box body will not block the operator's line of sight and light, thereby facilitating the inspection and repair work.

[0006] Furthermore, a rain shield is installed on the upper part of the box body, and multiple groups of evenly distributed heat dissipation holes are opened on both sides of the box body.

[0007] Furthermore, the protection component includes a ring, which is installed at the door lock. A groove is provided at the center of the ring, and the groove fits the door lock. A socket is provided at the upper end of the ring.

[0008] Furthermore, the protective component also includes a spring, which is fixedly installed inside the ring. The other end of the spring is connected to a connecting rod, and the end of the connecting rod away from the spring is rotatably connected to a protective cover. The protective cover is adapted to the ring, and an insertion rod is provided at the upper end of the protective cover, and the insertion rod is slidably adapted to the socket.

[0009] Furthermore, the displacement assembly includes a mounting plate, a slider is mounted at a middle position of a lower surface of the mounting plate, the slider is provided with two groups of sliding holes, and the mounting plate is slidably connected with the sliding holes via the slider.

[0010] Furthermore, a limit frame is installed at the lower end of the surface of the mounting plate, and the limit frame is slidably engaged with the limit plate. A lifting plate is connected to the upper end of the limit plate, and the lifting plate is in contact with the upper surface of the limit frame.

[0011] Furthermore, the sliding hole is adapted to the sliding rod, and the limiting plate is slidably engaged with the limiting groove.

[0012] The beneficial effects of the utility model are:

[0013] (1) The utility model can block rainwater from entering the door lock when it rains by setting a protective component, thereby preventing rainwater from rusting the door lock and causing the door lock to be unable to be opened, thereby increasing the service life of the door lock. When it rains, rainwater directly contacts the protective cover, thereby blocking rainwater from entering the door lock, pulling the protective cover outward, and the protective cover moves outward to drive the connecting rod to stretch the spring. When the insertion rod is completely out of the insertion hole, the protective cover is rotated to expose the door lock.

[0014] (2) By setting the shifting assembly, it is convenient to shift the installation plate to the box door, so that the electrical components are also shifted to the box door. When the electrical components are repaired, the box body will not block the operator's sight and light, which is convenient for maintenance work. The lifting plate is lifted upward to drive the limit plate to disengage from the limit groove, thereby releasing the limit on the installation plate. The lifting plate is pulled outward to drive the installation plate to move outward. When the slider is pressed against the box body, the lifting plate is released. The limit plate falls under the action of gravity, and the side of the limit plate close to the box body is pressed against the box body, completing the limit of the installation plate.

[0015] In summary, the utility model has the advantages of preventing door locks from rusting and facilitating maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

The lifting plate 302 moves upward to drive the limit plate 304 to move upward along the limit frame 303. The limit plate 304 moves upward and disengages from the limit slot 9. At this time, the limit on the mounting plate 301 is released, and the lifting plate 302 is pulled outward to drive the mounting plate 301 to move outward. The mounting plate 301 moves outward to drive the slider 305 to slide outward along the slide rod 7. When the slider 305 is pressed against the box body 1, the slider 305 is loosened. Open the lifting plate 302, and the limit plate 304 falls under the action of gravity. The side of the limit plate 304 close to the box body 1 is against the box body 1, completing the limitation of the mounting plate 301. At this time, the mounting plate 301 is completely moved out from the inside of the box body 1, so that the box body 1 will not block the electrical components, which is convenient for maintenance. Through the setting of the shifting component 3, it is convenient to shift the mounting plate 301 to the box door 5, so that the electrical components are also shifted to the box door 5.
