Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a distribution box. Background Art

[0002] The distribution box is an important component of the power system, used to distribute and control electricity. They are widely used in industrial, commercial and residential fields to ensure the safe, reliable and efficient transmission of electricity. However, the components inside the distribution box will emit heat during operation, so it is necessary to dissipate heat inside the distribution box. In the related art, a cooling fan is arranged in the distribution box, and the cooling fan conducts the heat of components such as switchgear, measuring instruments, protection circuits and auxiliary equipment through the heat dissipation holes. The heat dissipation area of ​​the heat dissipation holes of the traditional distribution box is fixed. In addition, the heat dissipation holes should not be designed to be too large to avoid failing to protect the isolation components. When the heat generated in the distribution box is large, the heat is not dissipated in time, resulting in poor heat dissipation effect.

[0003] At present, a Chinese patent with publication number CN111446649B discloses a distribution box, wherein the distribution box includes a housing, a heat dissipation fan, a heat dissipation hole adjustment component and a controller, the housing has a cavity, a fixed block is arranged in the cavity, a heat dissipation fan is arranged at the bottom of the housing, and the heat dissipation fan is arranged in the cavity, a heat dissipation hole is arranged on the side wall of the housing, an extension seat is arranged on one side of the heat dissipation hole, the heat dissipation hole adjustment component includes a temperature sensing strip, a rack, a gear and a rotating baffle, the rack is slidably arranged on the extension seat, the rack is meshed with the gear, a rotating shaft is arranged on one side of the rotating baffle, the rotating shaft is coaxially inserted on the gear, a pressure sensor is arranged on the extension seat, and the pressure sensor is electrically connected to the controller and the heat dissipation fan in turn. The gear, the moving shaft and the rotating baffle are driven to rotate in turn by the rack, so that the opening of the heat dissipation hole can be increased, and the heat dissipation effect of the distribution box is enhanced.

[0004] The above scheme arranges a rotating baffle structure that rotates and opens, and utilizes the temperature-sensitive strip structure to retract and contract. When the temperature rises, the temperature-sensitive strip extends, and then pushes the rack to move, and then drives the gear to drive the rotating baffle structure to rotate and open, thereby being able to adjust the size of the heat dissipation port of the distribution box. However, in actual use, a large part of the distribution boxes are installed on distribution facilities in outdoor environments. Therefore, after the above structure drives the rotating baffle to rotate and open, the rotating baffle is tilted. When the external environment is in rainy weather or a sprinkler truck passes by, rainwater or water sprayed by the sprinkler truck will flow into the distribution box along the tilted rotating baffle structure, causing rainwater or water sprayed by the sprinkler truck to enter the box, causing the humidity inside the distribution box to rise, which can easily cause internal components to age and be damaged due to the humid environment, and even short circuits may occur, affecting the service life and safety of the distribution box. Summary of the invention

[0005] The present invention is intended to provide a distribution box to avoid the risk of rain and water entering the distribution box when the heat dissipation holes are enlarged.

[0006] To achieve the above object, the present invention adopts the following technical scheme: a distribution box, including a distribution box body and a heat dissipation and rainproof adjustment mechanism, the distribution box body includes a cabinet, and the cabinet has heat dissipation windows on opposite side walls, and a slide groove is arranged in the heat dissipation window;

[0007] The heat dissipation and rainproof adjustment mechanism comprises a rainproof unit, a heat dissipation adjustment assembly and an adjustment drive assembly. The rainproof unit comprises a support assembly, and the support assembly comprises a waterproof part and a first support member. The first support member is rotatably connected to the side wall. One end of the waterproof part is fixedly connected to the free end of the first support member, and the other end is fixedly connected to the outer wall.

[0008] The heat dissipation adjustment component includes an adjustment plate, which is slidably arranged in the slide slot and can adjust the window opening range of the heat dissipation window;

[0009] The adjustment drive assembly includes a temperature measuring module, a controller, a driving member and a transmission assembly. The temperature measuring module includes a first temperature measuring element and a second temperature measuring element. The first temperature measuring element and the second temperature measuring element are both electrically connected to the controller and are fixedly arranged in the cabinet and outside the cabinet respectively. The driving member is fixedly arranged in the cabinet and can drive the adjustment plate to slide up and down through the transmission assembly. The controller is arranged in the cabinet and electrically connected to the driving member. The controller has a built-in warning value.

[0010] When the controller receives that the temperature difference measured by the first temperature measuring element and the second temperature measuring element is greater than the warning value, the controller controls the driving component to operate, so that the adjustment plate slides down to open the heat dissipation window, and at the same time drives the first support component to rotate through the driving part to unfold the waterproof part.

[0011] The beneficial effects of this solution are: 1. By adjusting the setting of the driving component, the temperature inside and outside the distribution box is used as a control factor to control the opening degree of the heat dissipation window. At the same time, the transmission component is used to associate the expansion degree of the rainproof component with the opening degree of the heat dissipation window, so that when the heat dissipation window is opened, the rainproof component is expanded together to avoid sudden situations when the heat dissipation window is opened, such as rain, sprinkler trucks passing by, etc., which cause rainwater to enter the distribution box and cause problems such as short circuits in the electrical components in the distribution box; 2. The controller is used to receive the data detected by the first temperature measuring element and the second temperature measuring element, and automatically adjust the opening degree of the heat dissipation window according to the detection data, so that the opening amplitude of the heat dissipation window is adapted to the heating condition in the distribution box, so that the temperature in the distribution box is within a reasonable range, so as to improve the safety and efficiency of the operation of the distribution box.

[0012] Furthermore, the driving member is a servo motor, and a driving gear is fixed on the output shaft of the servo motor. The transmission assembly also includes a first rotating member rotatably arranged on the side wall of the distribution box and meshing with the driving gear. The first supporting member includes a first connecting portion, and the first connecting portion is fixedly connected to the side wall of the first rotating member. Driving parts are fixed on both sides of the adjustment plate, and the driving part is provided with a rack meshing with the first rotating member.

[0013] Beneficial effect: The driving gear fixed on the servo motor is meshed with the first rotating member, and the first rotating member is meshed with the driving part, so that when the driving gear rotates, the first rotating member and the driving part present a linked transmission chain, and when the adjustment plate moves downward, the first support member rotates, so that the rainproof unit opens.

[0014] Furthermore, the transmission assembly also includes a second rotating member, which is rotatably arranged on the side wall and is coaxial with the first rotating member, and the side wall of the second rotating member is provided with a first arc-shaped slide groove, and the first arc-shaped slide groove is concentric with the second rotating member, and the side wall of the first rotating member is provided with a first protrusion, and the first protrusion extends into the first arc-shaped slide groove and slides with the first arc-shaped groove. The support assembly also includes a second support member, and the lower end of the second support member is fixedly connected to the second rotating member.

[0015] Furthermore, a second arc-shaped slide groove is provided on the other side wall of the second rotating member, and the second arc-shaped slide groove is concentric with the first arc-shaped slide groove and is staggered. The transmission assembly also includes a third rotating member, and the third rotating member is rotatably arranged on the side wall and is coaxial with the first rotating member. A second protrusion is provided on the side wall of the third rotating member, and the second protrusion extends into the second slide groove and slidably cooperates with the second slide groove. The support assembly also includes a third support member, and the lower end of the third support member is fixedly connected to the side wall of the third rotating member.

[0016] Beneficial effect: Through the arrangement of the first protrusion and the first arc-shaped groove and the second protrusion and the second arc-shaped groove, the first rotating member, the second rotating member and the third rotating member can start to rotate in sequence, thereby driving the first supporting member, the second supporting member and the third supporting member to rotate in sequence, and dividing the deployment of the rainproof unit into several stages, so as to complete the deployment action more smoothly and orderly. At the same time, the load of the driving member can be proportional to the deployment degree of the rainproof unit, thereby avoiding unnecessary energy loss.

[0017] Furthermore, the distribution box body also includes a first mounting plate that is slidably arranged inside the cabinet and parallel to the bottom of the cabinet, and a plurality of ventilation holes are arranged on the first mounting plate. A first mounting cavity is formed between the first mounting plate and the bottom of the cabinet. The heat dissipation unit also includes a cooling fan, which is fixedly installed in the first mounting cavity and electrically connected to the controller.

[0018] Beneficial effect: The cooling fan is arranged in the first installation cavity. When the cooling fan is running, the airflow passes through the ventilation holes to cool down the electrical components in the distribution box. When the airflow passes through the ventilation holes, turbulence is generated under the action of the ventilation holes to reduce the dead angle of airflow and improve the heat dissipation efficiency. At the same time, the cooling fan is electrically connected to the controller, and the controller is used to control the start and stop of the cooling fan, so that the cooling fan can play the corresponding function under the corresponding situation, thereby reducing energy consumption.

[0019] Furthermore, the distribution box body also includes a second mounting plate, a mounting strip for fixing electrical components is fixed on the outside of the second mounting plate, the second mounting plate is a heat-absorbing metal, the first temperature measuring element is fixedly connected to the second mounting plate, the second mounting plate is fixedly arranged in the cabinet and is perpendicular to the side wall and the first mounting plate, and a second mounting cavity is formed between the rear side walls of the cabinet, and the driving member is fixedly arranged in the second mounting cavity.

[0020] Beneficial effect: The electrical components are fixed on the second mounting plate made of heat-absorbing metal. When the electrical components generate heat, the heat dissipation area is increased by utilizing the thermal conductivity of the heat-absorbing metal, so that the emitted heat can be quickly diffused through the second mounting plate, thereby reducing the influence of the heating of the electrical components on the operation of the electrical components. At the same time, the first temperature measuring element is fixed on the second mounting plate, which can also be quickly detected. The second mounting plate is made of heat-absorbing metal plate. In addition, through the setting of the second mounting plate, a second mounting cavity is created, and the drive component is installed in the second mounting cavity, so that the front side of the distribution box is the same as the traditional distribution box, so as to adapt to the electrical components used in the existing distribution box, thereby reducing the replacement cost. At the same time, the wiring can be set on the back side of the mounting plate, so that the circuit layout of the distribution box is simpler, thereby improving the maintenance efficiency.

[0021] Furthermore, a mounting groove is arranged outside the heat dissipation window, and the first support member, the second support member and the third support member are all rotatably arranged in the mounting groove, and the lower surface of the mounting groove is inclined outward.

[0022] Beneficial effect: the lower surface of the installation groove is set to be inclined outward. When the awning is retracted, rainwater attached to the surface can flow out through the inclined lower surface, avoiding rainwater accumulation in the installation groove and affecting the use of the installation parts in the installation groove.

[0023] Furthermore, a window frame is formed between the installation groove and the heat dissipation window, the top surface of the window frame is coplanar with the lower surface of the installation groove, the window frame protrudes outward relative to the cabinet side wall, the cabinet side wall includes an inner wall and an outer wall, and the installation groove is arranged between the inner wall and the outer wall.

[0024] Beneficial effect: a window frame protruding outward is formed between the heat dissipation window and the installation groove, and the top surface of the window frame is coplanar with the lower surface of the installation groove, so that the lower surface of the installation groove protrudes outward. When rainwater flows downward along the side wall of the distribution box, the window frame and the installation surface can be used to drain the rainwater away from the installation groove, thereby preventing rainwater from entering the installation groove and corroding the metal parts in the installation groove.

[0025] Further, the adjustment plate moves a distance D, the first support member rotates with the length L of the first connection portion as the rotation radius, and the rotation angle of the first support member is α, wherein the moving distance D and the rotation radius L satisfy the following formula:

[0026] D<L(1-cosα)

[0027] D+cosα<L.

[0028] By associating the rotation radius of the first support member and the moving distance of the adjustment plate, it is ensured that the horizontal height of the lower edge of the first support member is always lower than the horizontal height of the upper edge of the adjustment plate, so as to avoid the situation where the heat dissipation window is opened and a horizontal jet of water appears, such as when a sprinkler truck passes by, and the horizontal jet of water enters the distribution box, causing a short circuit in the electrical components in the distribution box.

[0029] Furthermore, the waterproof part is made of a flexible material or a retractable material. BRIEF DESCRIPTION OF THE DRAWINGS
