Description

Technical Field

[0001] The present invention relates to energy storage cabinet technology, and in particular to a multifunctional photovoltaic energy storage cabinet and a use method thereof. Background Art

[0002] Solar energy is a renewable energy source. With the decreasing fossil fuels, solar energy has become an important part of human energy and is constantly developing. In the solar photovoltaic power generation system, the photovoltaic energy storage cabinet can store the electricity collected by the solar photovoltaic cell array and connect to the grid, which is a key component of solar photovoltaic power generation. In the solar photovoltaic power generation system, the photovoltaic energy storage cabinet can store the electricity collected by the solar photovoltaic cell array and connect to the grid, which is a key component of solar photovoltaic power generation. Existing photovoltaic energy storage cabinets are usually equipped with fans for heat dissipation, but the fans are fixedly installed and cannot meet the heat dissipation requirements of the densely discharged energy storage batteries in the energy storage cabinet.

[0003] A Chinese invention patent with publication number CN116885573A discloses a photovoltaic energy storage cabinet. The photovoltaic energy storage cabinet is provided with the installation mechanism. When in use, the fan is started to blow out the heat in the cabinet through the air outlet, and the filter screen filters the wind entering the cabinet. When the filter screen needs to be replaced, it is only necessary to turn on the motor, and the output end of the motor drives the fixed block to rotate, and the fixed block drives the supporting rod to slide in the through hole. The supporting rod slides in the through hole and drives the limiter to move upward, and the limiter drives the slider to move in the through hole. The filter mesh is then removed from the notch and the groove, and the filter mesh is aligned with the groove and pushed to a specified position. The motor is turned on and the motor is reversed to drive the fixing block to rotate. The fixing block drives the supporting rod to push the limiting member downward, and the limiting member drives the slider to move downward in the slide groove until the limiting member is inserted into the limiting groove on the new support member to complete the installation. In this way, the filter mesh can be replaced more conveniently without affecting the filtering effect.

[0004] Existing photovoltaic energy storage devices are usually designed as a whole according to the installed capacity. When the installed capacity is large, the overall volume of the cabinet will also increase accordingly. For example, some container-type energy storage cabinets are not conducive to transportation and installation, which makes the overall stability of the photovoltaic energy storage cabinet poor. In addition, when operating in remote areas, it is very easy to cause the gas circulation rate inside the photovoltaic energy storage cabinet to decrease when objects such as wind, sand or leaves are adsorbed on the vents, which can easily cause damage to the electrical components inside the photovoltaic energy storage cabinet.

One end of the cleaning component 2 is in contact with the outer surface of the ventilation plate 11, and the outer surface of the ventilation plate 11 is cleaned by the cleaning component 2.

[0043] In this embodiment, the cross-section of the ventilation plate 11 is circular, and a docking block is provided in the middle part of the ventilation plate 11. An annular mesh plate is provided between the docking block and the inner wall of the ventilation plate 11, and the outer surface of the mesh plate is fitted with the end of the cleaning component 2.

[0045] A bottom plate 23 is provided at one end of the connecting plate 22, and a plurality of groups of support blocks 24 are provided at the end of the bottom plate 23 away from the connecting plate 22, and the plurality of groups of support blocks 24 are evenly distributed at the end of the bottom plate 23, and a clamping block 25 is rotatably installed at the end of each support block 24, and an arc block 251 is provided at the end of the clamping block 25 away from the support block 24.

[0046] In this embodiment, the fixed block 21 is composed of a cylinder and a round rod, and the inner wall of the cylinder is slidably connected to the outer surface of the round rod. At the same time, the outer surface of the round rod is provided with rubber blocks or the like to have an anti-slip effect, so that when the round rod moves, the round rod can be restricted and can be fixed at any time when the round rod moves.

[0047] At the same time, the movable plate 28 is fixed by multiple sets of clamps 25 in cooperation with the arc block 251, and the movable plate 28 is tightly pressed against the annular grid plate by the fixed block 21 and the rotating plate 211. When the annular grid plate needs to be replaced, the rotating plate 211 is pushed outward by the fixed block 21, so that the movable plate 28 is separated from the annular grid plate, which facilitates the replacement of the annular grid plate.

[0048] Furthermore, a connecting rod 27 is provided at the end of the base plate 23, and a circular plate 26 is provided on the outer surface of the connecting rod 27. A slot hole 261 corresponding to the support block 24 is opened at one end of the circular plate 26.

[0049] Specifically, when the circular plate 26 moves up and down, it simultaneously drives the connecting block 262 arranged on its outer surface to move, thereby pushing the clamping block 25 to rotate around the supporting block 24, so that the end of the clamping block 25 away from the supporting block 24 moves toward the middle or expands outward, thereby fixing the movable plate 28.

[0050] Furthermore, a movable plate 28 is provided on the outer surface of the connecting rod 27 and at one end away from the circular plate 26. At the same time, a plurality of extension rods 281 are provided on the outer surface of the movable plate 28, and the locking extension rods 281 are evenly distributed on the outer surface of the movable plate 28. An annular groove 282 is provided at one end of the movable plate 28 close to the circular plate 26, and the inner wall of the annular groove 282 is slidably connected to the outer surface of the arc block 251.

[0051] Specifically, the outer surface of the extension rod 281 is provided with rubber, so that when the extension rod 281 rotates with the movable plate 28, impurities accumulated on the outer surface of the annular grid plate are removed, thereby ensuring smooth gas circulation inside the cabinet 1.

[0052] Furthermore, a power piece 221 is disposed in the inner cavity of the connecting plate 22 , and an output end of the power piece 221 penetrates and extends to the outside of the bottom plate 23 , while the output end of the power piece 221 is connected to the lower end of the circular plate 26 .

[0053] Specifically, the power member 221 is a component with telescopic function such as an electric telescopic rod, and is connected to an external control device. When the power member 221 is started, the circular plate 26 arranged at its output end can be driven to move up and down on the connecting rod 27, thereby fixing the movable plate 28.

[0054] At the same time, a device with power output such as a motor is provided at the end of the rotating plate 211, and is connected to an external control device. When the motor is started, the connecting plate 22 arranged at its output end is driven to rotate. When the connecting plate 22 rotates, the bottom plate 23 and the connecting rod 27 can drive the movable plate 28 to rotate, thereby cleaning the outer surface of the annular grid plate while accelerating the gas flow rate inside the cabinet 1.

[0055] Furthermore, the limiting assembly 3 is assembled at the lower end of the inner cavity of the cabinet 1 and is connected to the external positioning rod through the limiting assembly 3 .

[0056] The position limiting assembly 3 includes a fixed plate 31 connected to the inner wall of the cabinet 1, and a plurality of extension plates 311 are arranged on the outer surface of the fixed plate 31, and the plurality of extension plates 311 are evenly distributed on the outer surface of the fixed plate 31. An adjusting plate 32 is rotatably mounted on the upper end of the fixed plate 31, and an arc plate 321 corresponding to the extension plate 311 is arranged on the outer surface of the adjusting plate 32. A slider 322 is slidably mounted on the inner wall of each arc plate 321, and the outer surface of the lower end of the slider 322 is slidably connected to the inner wall of the extension plate 311.

[0057] An adjusting rod 312 is disposed at the lower end of the slider 322 , and a clamping plate 313 is disposed at one end of the adjusting rod 312 away from the slider 322 .

[0058] In this embodiment, when the adjusting plate 32 rotates, the arc plate 321 arranged on its outer surface is synchronously driven to rotate, wherein a slide groove is penetrated through one end of the arc plate 321, and the inner wall of the slide groove is slidably connected to the outer surface of the slider 322, so that when the arc plate 321 rotates, the slider 322 is synchronously driven to move along the guide groove provided at the upper end of the extension plate 311. Since the lower end of the slider 322 is provided with an adjusting rod 312, when the slider 322 moves, the adjusting rod 312 is synchronously driven to move outward.

[0059] At the same time, the end of the adjustment rod 312 is connected to the clamping plate 313, and the upper end of the clamping plate 313 after being combined is truncated into a cone shape, and the lower end is cylindrical. After the clamping plates 313 are combined, the positioning rod set on the ground is clamped, so that the cabinet 1 as a whole remains stable.

[0060] Furthermore, a sector plate 323 is provided at the upper end of the slider 322, and the outer surface of the sector plate 323 is slidably connected to the upper end of the adjustment plate 32. A gear block 33 is rotatably mounted at the upper end of the adjustment plate 32.

[0061] A driving member 34 is disposed on one side of the fixing plate 31 . A transmission block 341 is disposed at the output end of the driving member 34 . The outer surface of the transmission block 341 meshes with the outer surface of the gear block 33 .

[0062] Specifically, the driving member 34 is a device with power output such as a motor, and is connected to an external control device. When the driving member 34 is started, it synchronously drives the transmission block 341 arranged at its output end to rotate. At the same time, when the transmission block 341 rotates, it drives the gear block 33 to rotate. Since the end of the gear block 33 is fixedly connected to the upper end of the adjustment plate 32, when the gear block 33 rotates, it synchronously drives the adjustment plate 32 to rotate.

[0063] The end of the sector plate 323 is connected to the end of the slider 322, and when the slider 322 moves, the sector plate 323 is synchronously driven to move toward the middle or the outside, and the positioning rod is fixed with the clamping plate 313, so that the cabinet 1 remains stable as a whole.

[0064] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.
