Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power distribution, in particular to a photovoltaic power distribution box. Background Art

[0002] The distribution box is mainly used to reasonably distribute electrical energy and facilitate the opening and closing of circuits. It is an indispensable part of the photovoltaic power generation system. During use, many electrical components used to connect and control the circuit system will be installed inside the distribution box.

[0003] The existing photovoltaic distribution box generally includes a distribution box body and a box door that can be opened and closed and installed on the distribution box body. In order to ensure the heat dissipation effect of the electrical components installed in the distribution box body, the box door and the distribution box body are generally set at an interval. However, there is a risk of water and moisture entering between the box door and the distribution box body, which is very troublesome. In order to prevent the problem of water entering the distribution box body or a large amount of moisture entering, the box door with a sealing ring began to be put into use. However, directly sealing the box door and the distribution box body with a sealing ring will cause the problem of heat dissipation failure. Therefore, additional heat dissipation holes and corresponding heat dissipation fans are required, thereby increasing the production cost of the photovoltaic distribution box.

[0004] Therefore, the research purpose of the present invention is to design a photovoltaic distribution box that can effectively form a reasonable gas circulation effect to achieve heat dissipation of the distribution box, and can form sufficient waterproof and moisture-proof performance to ensure the operating stability and safety of the distribution box. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a photovoltaic distribution box, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A photovoltaic distribution box, comprising:

[0008] A distribution box body, wherein a first electrical component mounting plate is arranged in the distribution box body, and a baffle with a T-shaped cross section is arranged at the opening of the distribution box body;

[0009] The multifunctional protection mechanism comprises a sealing strip sleeved on the outer side of the baffle, the sealing strip is made of rubber material, and a hollow filling cavity is arranged on the outer side of the sealing strip; a plurality of air holes connected to the hollow filling cavity are evenly distributed on the sealing strip, and a plurality of spherical activated carbon particles with a particle size larger than the aperture of the air holes are filled in the hollow filling cavity; corresponding water retaining convex edges are integrally formed and arranged outwardly at the positions of the sealing strip where the hollow filling cavity is not arranged;

[0010] The box door can be opened and closed and is installed at the opening of the distribution box body. One side of the box door is rotatably installed to one side of the distribution box body, and the other side of the box door is locked and installed to the other side of the distribution box body through a corresponding lock; after the box door is closed to the opening of the distribution box body, the box door forms an extrusion abutment with the outer end of the sealing strip.

[0011] A corresponding clamping groove is arranged on one side of the sealing strip facing the baffle plate, and the sealing strip is clamped to the outer side of the baffle plate by the cooperation between the clamping groove and the baffle plate.

[0012] The sealing strip is provided with a filling hole connected to the hollow filling cavity, and a corresponding fixing plug is detachably installed at the filling hole.

[0013] The inner sides of the sealing strips are fixedly connected with corresponding supporting plates by gluing.

[0014] The supporting plate is made of engineering plastics or aluminum profiles.

[0015] The baffle is provided with a corresponding limiting opening at a position corresponding to the locking tongue of the lock.

[0016] A group of corresponding hinged plates are fixedly connected to one side of the baffle according to height, and a corresponding second electrical component mounting plate is hingedly installed between the hinged plates. An L-shaped limit plate corresponding to the second electrical component mounting plate is fixedly connected to the other side of the baffle, and the second electrical component mounting plate is fixedly installed on the L-shaped limit plate by cooperating with the L-shaped limit plate through a clamping shaft with a knob.

[0017] One end of the clamping shaft which is not connected to the knob is fixedly connected to a clamping plate which is matched with the L-shaped limiting plate.

[0018] 1) The utility model is provided with a circle of baffles with a T-shaped cross section at the opening of the distribution box body, and a multifunctional protective mechanism is added. After the box door is closed to the opening of the distribution box body, the box door forms an extrusion contact with the outer end of the sealing strip. During use, the air inside and outside the distribution box body can flow along the air holes on the sealing strip of the multifunctional protective mechanism to achieve heat dissipation of the distribution box. In the process of external air flowing through the sealing strip, the spherical activated carbon particles filled in the hollow filling cavity can adsorb moisture, thereby achieving a moisture-proof effect; once water enters along the gap between the distribution box body and the box door, the water entering can be blocked by the water retaining convex edge, so that the water is finally discharged along the gap between the distribution box body and the box door, thereby achieving a waterproof effect; and the internal hot air can also form a certain thermal drying effect on the spherical activated carbon particles during the outward circulation, thereby forming a regeneration function for the spherical activated carbon particles to extend the service life of the spherical activated carbon particles.

[0019] Thereby, a reasonable gas circulation effect can be effectively formed to achieve the heat dissipation of the distribution box, and sufficient waterproof and moisture-proof performance can be formed to ensure the operating stability and safety of the distribution box.

[0020] 2) After the box door of the utility model is closed to the opening of the distribution box body, the box door can form an extrusion abutment with the outer end of the sealing strip, so that a reasonable mutual extrusion force is formed between the spherical activated carbon particles filled in the hollow filling cavity of the sealing strip. Through the friction energy consumption between the surfaces of the spherical activated carbon particles, a certain vibration reduction and noise reduction effect can be effectively formed to reduce the low-frequency noise generated by the operation of many electrical components in the distribution box, thereby effectively improving the performance of the utility model.

[0021] 3) The inner side of the sealing strip of the utility model is fixedly connected with a supporting plate made of engineering plastic or aluminum profile by gluing, thereby improving the supporting rigidity of the hollow filling cavity portion of the sealing strip, so as to form a stable filling of the spherical activated carbon particles, thereby effectively improving the practical effect of the present invention.

[0022] 4) The utility model further adds a second electrical component mounting plate on the basis of the baffle, and fixes the second electrical component mounting plate by setting an L-shaped limiting plate, thereby effectively increasing the installation area of ​​the electrical components without affecting the installation operation of the electrical components, so as to further enhance the practical effect of the present invention.
