Description

Technical Field

[0001] The utility model relates to the field of distribution boxes, and particularly to a moisture-proof low-voltage integrated distribution box for outdoor use. Background Technique

[0002] The low-voltage integrated distribution box belongs to a kind of distribution box. The low-voltage integrated distribution box refers to a device used for power supply, circuit distribution, electric energy metering, protection control and other comprehensive purposes in the power system. When these devices are designed and installed in an outdoor environment, they are called low-voltage integrated distribution boxes for outdoor use.

[0003] In the prior art, the Chinese utility model patent with the publication number of "CN218770621U" and the patent name of "A Distribution Box JP Cabinet with Moisture-Proof Function" discloses a moisture-proof distribution box. It is recorded in this patent that "through an air pump, an air outlet pipe and an air inlet pipe, the air in the JP cabinet body can continuously circulate in the drying box. Through a replaceable air drying mechanism, the air passing through the drying box can be dried, thereby preventing the electronic components installed in the JP cabinet body from being affected by moisture. Through a plurality of wing bolts, the sealing plate can be hermetically installed on the drying box. Through two sealing cabinet doors, the JP cabinet body can be sealed. Through an air humidity sensor, the air humidity in the JP cabinet body can be monitored. Through a controller, the device can be controlled. Through a red indicator light and a green indicator light, prompts can be given to the staff, so as to facilitate the staff to replace a plurality of drying plates in time" and other technical solutions;

[0004] However, in the actual use process of this technical solution, when the drying plate has been used for a long time, in order to ensure the adsorption and drying effect of the drying plate on the moisture in the air of the distribution box, the drying plate needs to be replaced irregularly to prevent too much moisture on the drying plate from affecting the moisture-proof and dehumidifying effect of the distribution box. And when replacing the drying plate, it is necessary to unscrew the wing bolts to open the sealing plate before the drying plate can be replaced, and the operation is relatively cumbersome. Moreover, when the distribution box is used outdoors, in order to prevent water accumulation, it is usually installed at a certain height, which further brings inconvenience to the replacement of the drying plate;

[0005] Therefore, in order to solve the above technical problems, the utility model proposes a moisture-proof low-voltage integrated distribution box for outdoor use. Content of the Utility Model

[0006] The main purpose of the utility model is to provide a moisture-proof low-voltage integrated distribution box for outdoor use, which can effectively solve the problems in the background technique.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A moisture-proof low-voltage integrated distribution box for outdoor use, including a box body, a box door is provided at the front end of the box body, and a rain cover is provided on the top surface of the box body. A moisture-proof and dehumidifying mechanism is provided at the rear end of the box body, and the moisture-proof and dehumidifying mechanism includes an exhaust pipe, an exhaust fan, a dehumidification box, a filter frame, a dehumidification filter screen, an air heater, a humidity sensor and a controller. The exhaust pipe is fixedly connected to both sides of the box body, and the exhaust fan is fixedly connected inside the exhaust pipe. The dehumidification box is fixedly connected to the rear wall of the box body, and a U-shaped connecting pipe is connected between the exhaust pipe and the intake pipes on both sides of the dehumidification box. Two groups of symmetric filter frames are fixedly connected inside the dehumidification box, and a dehumidification filter screen is fixedly connected inside the filter frame. An air heater is also fixedly connected between the symmetric filter frames. The humidity sensor is fixedly connected to the inner wall of the dehumidification box, and the controller is fixedly connected to the bottom surface of the dehumidification box.

[0009] Preferably, exhaust ports are respectively opened on the left and right side walls of the box body.

[0010] Preferably, exhaust pipes are respectively fixedly installed on the left and right side walls of the box body and outside the exhaust ports, and an exhaust fan is fixedly installed inside the exhaust pipes.

[0011] Preferably, the dehumidification box is fixedly installed on the rear wall of the box body, and intake pipes are respectively fixedly installed on the left and right side walls of the dehumidification box. A U-shaped connecting pipe is fixedly installed between the intake pipe and the exhaust pipe.

[0012] Preferably, a group of symmetric filter frames are respectively fixedly installed on the left and right sides inside the dehumidification box, and a dehumidification filter screen is fixedly installed inside the filter frame. An air heater is also fixedly installed between the symmetric filter frames.

The exhaust fan, the air heater and the humidity sensor are all electrically connected to the controller through connecting wires.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In this utility model, the moisture-proof and dehumidifying mechanism is used in conjunction with the upper box body. When the box body is used outdoors, the exhaust fan is turned on through the controller, so that the exhaust fan can continuously extract the air inside the box body through the exhaust port, and then transport it to the dehumidification box through the intake pipe via the U-shaped connecting pipe. The moisture in the air inside the box body is adsorbed and filtered by the dehumidification filter screens in the two filter frames inside the dehumidification box. After dehumidification, the air will be discharged to the outside through the exhaust holes, ensuring that the air inside the box body is always in a dry state. Thus, the low-voltage comprehensive distribution box has the function of moisture-proof when used outdoors, preventing the electronic components inside the box from being damaged by moisture and affecting the normal use of the low-voltage comprehensive distribution box, and ensuring the service life of the moisture-proof low-voltage comprehensive distribution box;

[0016] At the same time, when the humidity sensor detects that the humidity in the dehumidification box exceeds the preset maximum value due to the adsorption of moisture by the dehumidification filter screens, the controller will turn on the air heater. After being powered on, the air heater heats the surrounding air, and can dry the dehumidification filter screens on both sides during the heating process. Furthermore, it ensures that the dehumidification filter screens can still play a good role in adsorbing and filtering the moisture in the air inside the box body after long-term use, and there is no need to replace the dehumidification filter screens.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Such as Figure 1 - Figure 4As shown in the figure, a moisture-proof low-voltage integrated distribution box for outdoor use includes a box body 1. A box door 2 is provided at the front end of the box body 1, and a rain shield 3 is provided on the top surface of the box body 1. The rain shield 3 can play a role in shielding rain for the box body 1, preventing rainwater from entering the box body 1 along the box body 1 through the heat dissipation holes provided on the box body 1 itself;

[0024] A moisture-proof and dehumidifying mechanism 4 is provided at the rear end of the box body 1. The moisture-proof and dehumidifying mechanism 4 includes an exhaust pipe 6, an exhaust fan 7, a dehumidification box 8, a filter frame 12, a dehumidification filter screen 13, an air heater 14, a humidity sensor 15, and a controller 16. The exhaust pipe 6 is fixedly connected to both sides of the box body 1, and the exhaust fan 7 is fixedly connected inside the exhaust pipe 6. The dehumidification box 8 is fixedly connected to the rear end wall of the box body 1, and a U-shaped connecting pipe 10 is connected between the exhaust pipe 6 and the intake pipes 9 on both sides of the dehumidification box 8. Two groups of symmetric filter frames 12 are fixedly connected inside the dehumidification box 8, and a dehumidification filter screen 13 is fixedly connected inside the filter frame 12. An air heater 14 is also fixedly connected between the symmetric filter frames 12. The humidity sensor 15 is fixedly connected to the inner wall of the dehumidification box 8, and the controller 16 is fixedly connected to the bottom surface of the dehumidification box 8.

[0025] As Figure 3 shown in the figure, exhaust ports 5 are respectively opened on the left and right side walls of the box body 1. Through the exhaust ports 5 provided on the box body 1, the air inside the box body 1 can be discharged to the outside;

[0026] As Figure 4 shown in the figure, exhaust pipes 6 are respectively fixedly installed on the left and right side walls of the box body 1 and are located outside the exhaust ports 5, and an exhaust fan 7 is fixedly installed inside the exhaust pipe 6. The exhaust fan 7 installed inside the exhaust pipe 6 extracts the air inside the box body 1 from the exhaust port 5. By continuously extracting the air inside the box body 1, it is possible to avoid moisture staying inside the box body 1 and ensure the dryness of the air inside the box body 1;

[0027] As Figure 4 shown in the figure, the dehumidification box 8 is fixedly installed on the rear end wall of the box body 1, and intake pipes 9 are respectively fixedly installed on the left and right side walls of the dehumidification box 8. A U-shaped connecting pipe 10 is fixedly installed between the intake pipe 9 and the exhaust pipe 6. The air extracted by the exhaust fan 7 will be discharged into the dehumidification box 8 from the intake pipe 9 through the U-shaped connecting pipe 10;

[0028] As Figure 4As shown in the figure, on the left and right sides inside the dehumidification box 8, a set of symmetrical filter frames 12 are fixedly installed respectively, and a dehumidification filter screen 13 is fixedly installed inside the filter frames 12. An air heater 14 is also fixedly installed between the symmetrical filter frames 12. A number of exhaust holes 11 are opened on the bottom surface of the dehumidification box 8 and located between the two sets of symmetrical filter frames 12. After the air in the box body 1 enters the dehumidification box 8 from both ends of the dehumidification box 8, the air will sequentially pass through the dehumidification filter screens 13 inside the symmetrical filter frames 12 installed on both sides inside the dehumidification box 8. The dehumidification filter screens 13 will adsorb and filter the moisture in the air, so as to achieve the purpose of dehumidifying the air in the box body 1, prevent the electronic components in the box body 1 from being damaged by moisture, and enable the low-voltage comprehensive distribution box to have the function of moisture-proof when used outdoors. And after the air heater 14 is powered on and heated, it can dry the dehumidification filter screens 13 on both sides. Not only can it ensure the dehumidification and moisture-proof effect of the air in the low-voltage comprehensive distribution box during long-term use, but also there is no need to replace the dehumidification filter screens 13;

[0029] As Figure 4 shown in the figure, a humidity sensor 15 is fixedly installed on the inner wall of the dehumidification box 8, and a controller 16 is fixedly installed on the left side of the bottom surface of the dehumidification box 8. The exhaust fan 7, the air heater 14 and the humidity sensor 15 are all electrically connected to the controller 16 through connecting wires. By simple programming, the controller 16 electrically controls the exhaust fan 7, the air heater 14 and the humidity sensor 15 under the connecting wires. After the exhaust fan 7 is controlled to start, the air in the box body 1 is pumped out. When the humidity sensor 15 detects that the humidity in the dehumidification box 8 exceeds the preset maximum due to the dehumidification filter screen 13, after the controller 16 receives the electrical signal of the humidity sensor 15, it turns on the air heater 14 to be powered on and heated to dry the dehumidification filter screen 13.

[0030] It should be noted that the present utility model is a moisture-proof low-voltage integrated distribution box for outdoor use. During the outdoor use of the low-voltage integrated distribution box, the controller 16 will turn on the exhaust fans 7 installed in the exhaust pipes 6 on the left and right sides of the control box body 1. After being powered on, the exhaust fans 7 will continuously extract the air inside the box body 1 through the exhaust ports 5 opened on the left and right sides of the box body 1 and discharge it into the U-shaped connecting pipe 10 connected to the exhaust pipes 6. And the air will enter the dehumidification box 8 through the intake pipes 9 on the left and right sides of the dehumidification box 8 installed on the rear end wall of the box body 1. When the air entering the dehumidification box 8 passes through the two groups of symmetric filter frames 12 installed in the dehumidification box 8, the dehumidification filter screens 13 installed in the filter frames 12 will adsorb and filter the moisture in the passing air. After the adsorbed and filtered air forms a convection in the central part of the dehumidification box 8, it will be discharged to the outside through the exhaust holes 11 as a vent. Thus, by continuously extracting the air inside the box body 1 and performing adsorption and filtration dehumidification, it can ensure that the air inside the box body 1 always remains dry, enabling the low-voltage integrated distribution box to have the function of moisture-proof when used outdoors. At the same time, after long-term dehumidification of the air inside the box body 1, when the humidity sensor 15 installed in the dehumidification box 8 monitors that the humidity inside the dehumidification box 8 is greater than the preset maximum value due to the adsorption and filtration effect of the dehumidification filter screen 13, it will transmit the monitored electrical signal to the controller 16. After analysis and judgment, the controller 16 will control and turn on the air heater 14 installed between the symmetric filter frames 12 in the dehumidification box 8. After being powered on, the air heater 14 will heat the surrounding air and dry the moisture adsorbed and filtered on the dehumidification filter screens 13 in the two side filter frames 12 during the heating process until the humidity sensor 15 monitors that the humidity inside the dehumidification box 8 is lower than the preset minimum value, and then the controller 16 will turn off the air heater 14. Furthermore, it can ensure that the dehumidification filter screen 13 can still have a good adsorption and filtration effect on the moisture of the air inside the box body 1 after long-term use without the need to replace the dehumidification filter screen, so as to achieve the purpose that the moisture-proof and dehumidification mechanism 4 cooperates with the low-voltage integrated distribution box to be convenient for outdoor use and realize the moisture-proof function of the low-voltage integrated distribution box.

[0031] In summary, the above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components therein can be replaced with equivalents, or some of the technical features can be equivalently replaced. All should be included within the protection scope of the present utility model within the spirit and principle of the present utility model.
