Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, and specifically relates to a distribution cabinet with a dehumidification function. Background Technique

[0002] The distribution cabinet is an important part of the power system. It has the functions of power distribution, power control, and power system protection. At the same time, during operation, it also has the functions of monitoring and measurement, such as monitoring voltage, current, etc. The distribution cabinet enables the normal operation of the power system;

[0003] When the distribution cabinet is used outdoors, due to the temperature difference between the inside and outside of the distribution cabinet, moisture may condense. The condensation of moisture will affect the normal operation of the internal circuit of the cabinet body and will also corrode the materials inside the cabinet body, shortening the service life of the cabinet body and the materials inside the cabinet body;

[0004] To solve the above defects, the existing patent 1 (Chinese patent with the application number: CN202110644880.6, and the application date: June 9, 2021) is a moisture-proof distribution cabinet. When it works, it reduces the air humidity of the distribution cabinet, ensures a dry operation environment in the operation room, avoids leakage or short circuit of components caused by the humid air inside the distribution cabinet, and increases the service life of the components inside the distribution cabinet;

[0005] The existing patent 2 (Chinese patent with the application number: CN201911394165.0, and the application date: December 30, 2019) is a high-strength distribution cabinet. When it works, it has the effect of continuously absorbing water in the air inside the distribution cabinet to reduce the air humidity so as to protect the electrical components inside the distribution cabinet;

[0006] During the use process, dehumidification is achieved by absorbing water vapor, resulting in high costs and energy consumption. Moreover, the above applications do not have the function of accelerating the air circulation inside the cabinet body during use, and thus do not have the effect of air-drying dehumidification, with high use costs and poor economic benefits.

[0007] In view of the above problems, it is urgent to innovate and design on the basis of the original distribution cabinet. Content of the Utility Model

[0008] The purpose of the utility model is to provide a distribution cabinet with a dehumidification function to solve the problems mentioned in the above background technique, that is, during use, it does not have the function of accelerating the air circulation inside the cabinet body, and thus does not have the effect of air-drying dehumidification, with high use costs and poor economic benefits.

[0009] To achieve the above object, the present utility model provides the following technical solutions: A power distribution cabinet with a dehumidification function, including a cabinet body, a door panel is hingedly connected to the surface of the cabinet body, an inductor is fixedly connected to the inner wall of the cabinet body, a motor is bolted to the back of the cabinet body, and the inductor and the motor are electrically connected;

[0010] It further includes:

[0011] A fan, the fan is fixedly connected to the end of the output end of the motor, and a pulley is sleeved on the middle position of the output end of the motor;

[0012] A connecting shaft, the connecting shaft is rotatably arranged inside the cabinet body, and a baffle is slidably connected inside the cabinet body;

[0013] A rotating shaft, the rotating shaft is rotatably arranged inside the cabinet body, a fan blade is fixedly connected to the end of the rotating shaft, and heat dissipation openings are evenly spaced on both left and right sides of the cabinet body.

[0014] Preferably, the other side of the pulley is sleeved on the surface of the connecting shaft, a cam is fixedly connected to the surface of the connecting shaft, and the surface of the cam is in contact with the surface of the baffle.

[0015] Preferably, a heat dissipation net is fixedly connected to the surface of the cabinet body, the heat dissipation nets are symmetrically distributed about the center of the cabinet body, the heat dissipation nets correspond to the baffles one by one, and the surface of the baffle is in contact with the surface of the cam.

[0016] Preferably, a limiting rod is fixedly connected to the inner wall of the cabinet body, the top view of the limiting rod is an inverted "L" structure, and the baffle is sleeved on the surface of the limiting rod.

[0017] Preferably, a return spring for elastic reset is fixedly connected to the end of the limiting rod, and the other side of the return spring is fixedly connected to the inner wall of the baffle.

[0018] Preferably, tooth blocks are fixedly connected at equal intervals on the upper surface of the baffle, and a gear meshing with the tooth blocks is fixedly connected to the surface of the rotating shaft.

[0019] Preferably, the fan blades are symmetrically distributed about the center of the cabinet body.

[0020] Compared with the prior art, the beneficial effects of the present utility model are: The power distribution cabinet with a dehumidification function adopts a new structural design, and the specific content is as follows:

[0021] During the use of the power distribution cabinet with dehumidification function, the humidity inside the cabinet is sensed by a sensor. When the humidity exceeds the standard, the motor starts. At this time, the motor drives the fan to rotate. When the fan rotates, it cooperates with the heat dissipation outlet to accelerate the circulation of the gas inside the cabinet, facilitating the discharge of moisture. That is, the cabinet has a rapid dehumidification function, ensuring the normal operation of the components inside the cabinet and also delaying the overall service life of the device.

[0022] Further, when the motor is working, the motor drives the connecting shaft to rotate through a pulley. When the connecting shaft rotates, it drives the cam to rotate synchronously. Then, the cam intermittently pushes the baffle. At this time, under the action of the cam, the limit rod and the return spring, the baffle makes a reciprocating linear motion in the horizontal direction. Then, the heat dissipation net will intermittently open and close. At this time, the heat dissipation net and the heat dissipation outlet cooperate, and also accelerate the circulation of the air inside the cabinet, optimizing the dehumidification effect.

[0023] When the baffle of the power distribution cabinet with dehumidification function is intermittently pushed by the cam, the tooth block will move synchronously. At this time, the tooth block drives the rotating shaft to rotate through the gear. Then, the rotating shaft drives the fan blade to rotate. When the fan blade rotates, it also accelerates the airflow inside the cabinet, enabling the moisture to be quickly taken away.

[0024] Further, the fan blades are symmetrically distributed inside the cabinet, optimizing the dehumidification effect.

[0025] (3) After the moisture inside the cabinet of the power distribution cabinet with dehumidification function is removed, the motor stops working. At this time, the fan and the fan blade stop working. Then, the cabinet dissipates heat normally through the heat dissipation outlet, and the sensor and the motor are in a standby pre-working state.

Specific implementation mode

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figures 1-7 , the present utility model provides the following technical solutions:

[0036] Embodiment 1: By setting the inductor 2 and the motor 3, the fan 4 can work quickly, so that the moisture inside the cabinet body 1 can be quickly dried, having a dehumidifying effect, as Figures 1-2 shown:

[0037] It includes a cabinet body 1, the surface of the cabinet body 1 is hingedly connected with a door panel, and an inductor 2 is fixedly connected to the inner wall of the cabinet body 1, and a motor 3 is bolted to the back of the cabinet body 1, and the inductor 2 and the motor 3 are electrically connected;

[0038] A power distribution cabinet with a dehumidifying function further includes:

[0039] A fan 4, the fan 4 is fixedly connected to the end of the output end of the motor 3, and a pulley 6 is sleeved and connected to the middle position of the output end of the motor 3, a connecting shaft 5, the connecting shaft 5 is rotatably arranged inside the cabinet body 1, and a baffle 11 is slidably connected inside the cabinet body 1;

[0040] A rotating shaft 13, the rotating shaft 13 is rotatably arranged inside the cabinet body 1, and a fan blade 15 is fixedly connected to the end of the rotating shaft 13, and heat dissipation ports 17 are evenly spaced on the left and right sides of the cabinet body 1.

[0041] When the cabinet body 1 is working, it dissipates heat normally through the heat dissipation ports 17. When the moisture inside the cabinet body 1 is relatively heavy, the inductor 2 starts the motor 3, and the motor 3 drives the fan 4 to rotate. At this time, the fan 4 plays a role in drying, and the cabinet body 1 can be quickly dehumidified.

[0042] Embodiment 2: Different from Embodiment 1, the heat dissipation net 9 can be intermittently opened and closed. The heat dissipation net 9 cooperates with the heat dissipation port 17 to accelerate the air flow inside the cabinet 1, facilitating the moisture to be taken out of the cabinet 1. For example, Figure 3 and Figure 4 as shown:

[0043] The other side of the pulley 6 is sleeved and connected to the surface of the connecting shaft 5, and a cam 8 is fixedly connected to the surface of the connecting shaft 5. The surface of the cam 8 is in contact with the surface of the baffle 11. The heat dissipation net 9 is fixedly connected to the surface of the cabinet 1, and the heat dissipation nets 9 are symmetrically distributed about the center of the cabinet 1. The heat dissipation nets 9 and the baffles 11 correspond one by one, and the surface of the baffle 11 is in contact with the surface of the cam 8.

[0044] The limiting rod 10 is fixedly connected to the inner wall of the cabinet 1. The top view of the limiting rod 10 is an inverted "L" structure. The baffle 11 is sleeved and connected to the surface of the limiting rod 10. A return spring 16 for elastic reset is fixedly connected to the end of the limiting rod 10, and the other side of the return spring 16 is fixedly connected to the inner wall of the baffle 11.

[0045] When the motor 3 works, the motor 3 drives the connecting shaft 5 to rotate through the pulley 6. When the connecting shaft 5 rotates, it drives the cam 8 to rotate synchronously. Then the cam 8 will intermittently push the baffle 11. When the cam 8 pushes the baffle 11, the baffle 11 will move towards the side position of the cabinet 1. At this time, under the action of the limiting rod 10, the baffle 11 moves in the horizontal direction (while the return spring 16 is compressed). When the cam 8 continues to rotate until it is no longer in contact with the baffle 11, the baffle 11 moves back under the action of the return spring 16. Repeating the above process, the baffle 11 makes a reciprocating linear motion in the horizontal direction under the action of the cam 8, the limiting rod 10 and the return spring 16. Then the heat dissipation net 9 will be intermittently opened and closed. At this time, the heat dissipation net 9 and the heat dissipation port 17 cooperate, and also accelerate the air flow inside the cabinet 1, optimizing the dehumidification effect.

[0046] Embodiment 3: Different from Embodiment 2, the fan blades 15 provided play a role in assisting to accelerate the air flow. For example, Figures 5-7 as shown:

[0047] The upper surface of the baffle 11 is fixedly connected with tooth blocks 12 at equal intervals. A gear 14 meshing with the tooth blocks 12 is fixedly connected to the surface of the rotating shaft 13. The fan blades 15 are symmetrically distributed about the center of the cabinet 1.

[0048] When the baffle 11 is intermittently pushed by the cam 8, the tooth block 12 will move synchronously. At this time, the tooth block 12 drives the rotating shaft 13 to rotate inside the cabinet body 1 through the gear 14. When the rotating shaft 13 rotates, it drives the fan blade 15 to rotate synchronously. When the fan blade 15 rotates, it also accelerates the air flow inside the cabinet body 1, so that the moisture is quickly taken away, thereby optimizing the dehumidification effect of the cabinet body 1, ensuring the normal operation of the components inside the cabinet body 1, and at the same time delaying the overall service life of the device.

[0049] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
