Description

Technical Field

[0001] This utility model belongs to the field of electrical control box technology, and in particular relates to an electrical control box with good sealing effect. Background Technology

[0002] As an indispensable electrical equipment in industrial production, construction engineering, municipal facilities and other fields, the electrical control box is mainly used to centrally install various electrical components such as circuit breakers, contactors, relays, and instruments, and to provide protection, control and power distribution functions for the normal operation of the electrical system.

[0003] To prevent internal electrical components from overheating due to operating heat, existing electrical control boxes typically require heat dissipation structures. Common heat dissipation methods include opening ventilation holes on the side walls or top of the box, or installing louvered ventilation openings. While these structures can achieve air circulation and dissipate heat from the box to some extent, they compromise the overall airtightness of the control box. When the control box is in a humid environment, such as workshops in the rainy season in southern China or outdoor rainy areas, a large amount of moisture in the air can enter the box through the ventilation holes or gaps in the louvers. In rainy weather, rainwater may even splash directly into the box or seep in with the airflow. At the same time, the door structure of existing electrical control boxes is relatively simple, mostly relying on the natural fit between the door and the box frame to achieve closure. There are often unavoidable gaps between the door and the box, and the lack of a dedicated sealing reinforcement structure makes it easy for moisture to enter the box through these gaps.

[0004] To address these issues, we provide an electrical control enclosure with excellent sealing performance. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical control box with good sealing performance. By combining the sealing door assembly and the ventilation assembly, the problem of poor sealing performance caused by the simple door structure and heat dissipation structure of the electrical control box in the prior art is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an electrical control box with good sealing performance, comprising a box body, a sealing door assembly on the front of the box body, a cooling fan on one side of the box body, a ventilation assembly on the other side of the box body, a temperature sensor fixedly connected to the top of one side of the inner cavity of the box body, the sealing door assembly including a box door, one side of the box door being movably connected to the surface of the box body, an elastic element fixedly connected to the edge of the back of the box door, a pressure frame fixedly connected to one end of the elastic element, a baffle fixedly connected to the front of the inner cavity of the box body, the back of the pressure frame abutting against the front of the baffle frame, the ventilation assembly including a motor housing, one side of the motor housing being fixedly connected to the surface of the box body, a drive motor being disposed in the inner cavity of the motor housing, a drive shaft being fixedly connected to the output end of the drive motor by bolts, a turntable fixedly connected to one end of the drive shaft, a sealing plate fixedly connected to one side of the turntable, and ventilation holes being provided on both the turntable and the surface of the box body.

[0008] The present invention is further configured such that a through groove is provided on one side of the inner cavity of the box, and the air outlet of the cooling fan is located in the inner cavity of the through groove. When the cooling fan is installed on one side of the box, its air outlet is inserted into the inner cavity of the through groove, and the operation of the cooling fan draws external air into the inner cavity of the box.

[0009] The present invention is further configured such that a mounting plate is fixedly connected to the rear side of the inner cavity of the box, and the surface of the mounting plate is provided with mounting holes. Several mounting plates with mounting holes on their surfaces can install various electrical components such as circuit breakers, contactors, relays, and instruments into the inner cavity of the box.

[0010] The present invention is further configured such that an anti-pressure plate is fixedly connected to the top of the box, and a rainproof plate is fixedly connected to the top of the anti-pressure plate through a buffer pad. The buffer and anti-pressure structure composed of the anti-pressure plate and the buffer pad can protect the top of the box, and the rainproof plate can guide rainwater to the sides of the box.

[0011] The present invention is further configured such that a support frame is fixedly connected to the bottom of the box, and a support pad is fixedly connected to the bottom of the support frame. The support structure composed of the three sets of support frames and support pads can provide stable support for the bottom of the box and can prevent ground moisture from corroding the box to a certain extent.

[0012] The present invention is further configured such that a pressing plate is movably connected to one side of the top of the box body, the back of the pressing plate is in close contact with the surface of the box door, and the pressing plate is rotated so that its back is in close contact with the surface of the box door, thereby improving the closing stability of the box door through the limiting effect of the pressing plate.

[0013] The present invention is further provided that a maintenance shell is provided on the front side of the motor housing, and one side of the maintenance shell is fixedly connected to the motor housing by bolts. By unscrewing the bolts connecting the maintenance shell to the motor housing on one side, the maintenance shell can be removed to inspect and maintain the drive motor inside the motor housing.

[0014] The present invention is further provided that a protective shell is provided on one side of the housing and outside the cooling fan. The top and bottom of the protective shell are fixedly connected to mounting plates. The protective shell is installed on one side of the housing through the mounting plates, surrounding the cooling fan and providing protection for the cooling fan.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model has advantages in the coordinated control of heat dissipation and sealing. When the inner cavity of the box does not need heat dissipation, the control mechanism can turn off the heat dissipation fan and start the drive motor to run, so that the ventilation holes of the turntable are staggered with the ventilation openings of the box, and form a closed structure with the sealing plate. This not only ensures the sealing performance in the non-heat dissipation state, but also prevents external dust and moisture from entering the inner cavity, thus strengthening the overall sealing effect of the box.

[0017] 2. This utility model has significant advantages in basic sealing. When the door is closed, the elastic element drives the pressure frame and the baffle frame to press tightly together. The elastic force generated by the deformation of the elastic element makes the pressure frame press tightly against the baffle frame, which effectively improves the sealing performance between the door and the box body and can fundamentally reduce the possibility of external impurities and moisture intrusion.

Detailed Implementation

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figure 1-6 This utility model relates to an electrical control box with good sealing performance, comprising a box body 1, a sealing door assembly 2 on the front of the box body 1, a cooling fan 3 on one side of the box body 1, a ventilation assembly 4 on the other side of the box body 1, a temperature sensor 5 fixedly connected to the top of one side of the inner cavity of the box body 1, the sealing door assembly 2 including a door 201, one side of the door 201 being movably connected to the surface of the box body 1, an elastic element 202 fixedly connected to the edge of the back of the door 201, and a pressure frame 203 fixedly connected to one end of the elastic element 202, the inner cavity of the box body 1... A baffle 204 is fixedly connected to the front side, and the back of the pressure frame 203 is in close contact with the front of the baffle 204. The ventilation component 4 includes a motor housing 401. One side of the motor housing 401 is fixedly connected to the surface of the housing 1. A drive motor 402 is provided in the inner cavity of the motor housing 401. A drive shaft 403 is fixedly connected to the output end of the drive motor 402 by bolts. A turntable 404 is fixedly connected to one end of the drive shaft 403. A sealing plate 405 is fixedly connected to one side of the turntable 404. Ventilation holes 406 are provided on the surface of both the turntable 404 and the housing 1.

[0029] Specifically: The door 201 is closed and locked by the lock body. As the door 201 closes, the elastic element 202 on the back of the door 201 drives the pressure frame 203 to move to the back of the pressure frame 203 and press against the front of the baffle 204. During this process, the elastic element 202 is deformed by the pressure of the door 201. The elastic force of the elastic element 202 makes the pressure frame 203 press tightly against the baffle 204, thereby improving the sealing between the door 201 and the box 1. When the inner cavity of the box 1 is overheated, the temperature sensor 5 transmits the abnormal temperature signal to the control mechanism. The control mechanism starts the drive motor 402 and the cooling fan 3. The output end of the drive motor 402 drives the drive shaft 403 to rotate. The drive shaft 403 drives the turntable 404 to rotate until the ventilation hole 406 on the surface of the turntable 404 coincides with the ventilation hole 406 on the surface of the box 1, thereby forming a heat dissipation channel. Under the action of the cooling fan 3, an air circulation environment is formed in the inner cavity of the box 1 to achieve heat dissipation.

[0030] Example 2

[0031] Please see Figure 1-6 Based on Embodiment 1, a through groove 6 is provided on one side of the inner cavity of the housing 1. The air outlet of the cooling fan 3 is located in the inner cavity of the through groove 6. A mounting plate 7 is fixedly connected to the rear side of the inner cavity of the housing 1. Mounting holes are provided on the surface of the mounting plate 7. A pressure-resistant plate is fixedly connected to the top of the housing 1. A rainproof plate is fixedly connected to the top of the pressure-resistant plate through a buffer pad. A support frame is fixedly connected to the bottom of the housing 1. A support pad is fixedly connected to the bottom of the support frame. A pressing plate is movably connected to one side of the top of the housing 1. The back of the pressing plate is in close contact with the surface of the door 201. A maintenance shell is provided on the front of the motor housing 401. One side of the maintenance shell is fixedly connected to the motor housing 401 through bolts. A protective shell is provided on one side of the housing 1 and outside the cooling fan 3. Mounting plates are fixedly connected to the top and bottom of the protective shell.

[0032] Specifically: When the cooling fan 3 is installed on one side of the enclosure 1, its outlet end is inserted into the inner cavity of the through groove 6. The cooling fan 3 draws outside air into the inner cavity of the enclosure 1. Several mounting plates 7 with mounting holes on their surfaces can install various electrical components such as circuit breakers, contactors, relays, and instruments into the inner cavity of the enclosure 1. The buffer and pressure-resistant structure composed of the pressure-resistant plate and the buffer pad can protect the top of the enclosure 1. The rainproof plate can guide rainwater to the sides of the enclosure 1. The support structure composed of three sets of support frames and support pads can protect the enclosure. The bottom of the box 1 is stably supported and can prevent ground moisture from corroding the box 1 to a certain extent. Rotate the clamping plate so that its back is pressed against the surface of the box door 201. The closing stability of the box door 201 is improved by the limiting effect of the clamping plate. Unscrew the bolts connecting the inspection shell to the motor shell 401 on one side, and the inspection shell can be removed to inspect and maintain the drive motor 402 inside the motor shell 401. The protective shell is installed on one side of the box 1 through the mounting plate, which surrounds the cooling fan 3 and can protect the cooling fan 3.

[0033] The working principle of this utility model is as follows: After various electrical components such as circuit breakers, contactors, relays, and instruments are installed in the inner cavity of the enclosure 1 via the mounting plate 7, the enclosure door 201 is closed and locked by the lock body. As the enclosure door 201 closes, the elastic element 202 on the back of the enclosure door 201 drives the pressure frame 203 to move until the back of the pressure frame 203 abuts against the front of the stop frame 204. During this process, the elastic element 202 is deformed by the pressure of the enclosure door 201, and the elastic force of the elastic element 202 makes the pressure frame 203 press tightly against the stop frame 204. The frame 204 is used to improve the sealing between the door 201 and the box 1. When the temperature inside the box 1 is within the set threshold range and no heat dissipation is required, the control mechanism turns off the cooling fan 3 and turns on the drive motor 402. The output end of the drive motor 402 drives the drive shaft 403 to rotate. The drive shaft 403 drives the turntable 404 to rotate until the ventilation holes 406 on the surface of the turntable 404 are misaligned with the ventilation openings on the surface of the box 1. Together with the sealing plate 405, a closed structure is formed between the turntable 404 and the box 1 to prevent external dust and moisture from entering the inner cavity of the box 1.
