Description

Technical Field

[0001] This utility model belongs to the field of wind power photovoltaic cabinet technology, specifically relating to a wind power photovoltaic cabinet with moisture-proof and heat dissipation functions. Background Technology

[0002] As an important component of wind and solar power stations, wind and solar power cabinets are mainly used to install and protect various electrical components, such as inverters, controllers, circuit breakers, and terminals.

[0003] Most existing wind power solar cabinets suffer from poor moisture protection and heat dissipation. Especially in humid and high-temperature environments, the electrical components inside the cabinet are prone to moisture and overheating, leading to frequent equipment failures and reducing the reliability and lifespan of the system. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a wind power photovoltaic cabinet with moisture-proof and heat dissipation functions, thereby solving the problem that most existing wind power photovoltaic cabinets have poor moisture-proof and heat dissipation effects, leading to frequent equipment failures and reducing the reliability and service life of the system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wind power photovoltaic cabinet with moisture-proof and heat dissipation functions, comprising a cabinet body, a cabinet door hinged on the front side of the cabinet body, and several mounting rails equidistantly spaced inside the cabinet body relative to the inner wall of the cabinet door. A cavity one and a cavity two are respectively opened on the two sides of the cabinet body. Cavity one connects to a heat dissipation component, which is housed within an outer shell. The outer shell is fixed to the bottom of the cabinet body. Support rods are installed at the four corners of the bottom of the cabinet body. Cavity two connects to an exhaust component, which is connected to a one-way valve. An angle adjustment component is located at the center of the top of the cabinet body, and the angle adjustment component is connected to the center of the bottom of a mounting frame. A sunshade is fitted onto the top of the mounting frame. A sealing ring is provided on the inner side of the cabinet body.

[0006] The beneficial effects of this utility model are:

[0007] By incorporating heat dissipation and ventilation components, effective heat dissipation is achieved inside the cabinet, while preventing dust and moisture from entering, thus improving the equipment's moisture resistance.

[0008] The cabinet is equipped with an angle adjustment component and a sunshade. The angle of the sunshade can be adjusted according to the season to block direct sunlight, reduce the surface temperature of the cabinet, and reduce the impact of heat radiation on the electrical components inside the cabinet.

[0009] The mounting bracket and sunshade are designed to be detachable, facilitating subsequent maintenance and replacement, and improving the ease of use and maintainability of the equipment.

[0010] To dissipate heat from electrical components:

[0011] As a further improvement to the above technical solution: the heat dissipation component consists of a heat dissipation fan, a waterproof and breathable membrane, a first fan, and a cooling semiconductor. An installation window is provided on one side of the inner wall of the outer casing, and a cooling semiconductor is fixed inside the installation window. The cooling surface of the cooling semiconductor faces the inside of the outer casing, and the heat dissipation surface of the cooling semiconductor faces one side of the outer casing. A heat dissipation fan is provided on one side of the outer casing, corresponding to the heat dissipation surface of the outer casing. The first fan is fixed at the bottom of the inner interior of the outer casing. An installation window is provided on the other side of the inner wall of the outer casing, and a waterproof and breathable membrane is provided inside the second installation window. A temperature sensor is installed at the top of the cabinet. The top of the outer casing is connected to a conveying cavity, which is located at the bottom of the cabinet and is connected to the bottom of cavity one.

[0012] The beneficial effects of this improvement are as follows: the controller starts the cooling fan, fan one, and cooling semiconductor. The rotating fan one transports external air, and the activated cooling semiconductor cools the transported air. The cooled air flows into cavity one through the delivery chamber. The waterproof and breathable membrane ensures air circulation while preventing dust and moisture from entering.

[0013] To ensure that air can only flow in one direction:

[0014] As a further improvement to the above technical solution: the inner walls on both sides of the cabinet are provided with a number of ventilation holes that are equidistantly spaced through cavity one and cavity two, respectively. The inner wall on the other side of cavity two is provided with a number of installation windows three that are equidistantly spaced through the cabinet, and each installation window three is equipped with a one-way valve.

[0015] The beneficial effects of this improvement are as follows: the cold air flowing into cavity one enters the cabinet through the vent, and the cold air blows heat towards cavity two, while the hot air is discharged outward through the one-way valve. The one-way valve ensures that the air can only flow in one direction, and at the same time, it can effectively block moisture and dust.

[0016] To block direct sunlight, lower surface temperature, and reduce the impact of heat radiation on internal electrical components:

[0017] As a further improvement to the above technical solution: the angle adjustment assembly consists of a mounting plate, a worm gear, a worm, a limiting plate, and a motor. Limiting plates are installed at opposite ends of the top of the cabinet. The mounting plates are rotatably connected to opposite sides of both sets of limiting plates. Worm gears are fixed to the inner sides of both sets of mounting plates. The top of the mounting plate is connected to the bottom of the mounting frame. One side of the worm gear meshes with the worm, and both ends of the worm are provided with baffles. One end of the worm is rotatably connected to one set of baffles, and the other end of the worm passes through and is rotatably connected to the other set of baffles. The other end of the worm is connected to the sub-shaft of the motor, and the motor is fixed to the top of the cabinet.

[0018] The beneficial effects of this improvement are as follows: the user starts the motor through the controller to drive the worm gear to rotate. At this time, the rotating worm gear drives the worm wheel that is meshed with it to rotate. The mounting bracket will then rotate around the axis of the worm wheel, thereby completing the angle adjustment of the sunshade. This allows the sunshade to be adjusted according to the season, blocking direct sunlight, reducing surface temperature, and reducing the impact of heat radiation on internal electrical components.

[0019] To facilitate the removal and installation of the sun visor:

[0020] As a further improvement to the above technical solution: the top of the mounting bracket is fitted with a sunshade, and bolts are threaded through both sides of the mounting bracket, with one end of the bolt threadedly connected to both sides of the sunshade.

[0021] The beneficial effect of this improvement is that the sun visor can be removed by turning the bolts, making it convenient for subsequent maintenance.

[0022] In order to unify the control of this device:

[0023] As a further improvement to the above technical solution: a controller is provided on the front side of the cabinet door. The controller consists of a microcontroller, a relay, and a control switch. The controller is electrically connected to a cooling fan, a fan, a cooling semiconductor, and a motor.

[0024] The beneficial effect of this improvement is that it enables unified control of the device.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description
