Technical Field

[0001] The invention relates to a rainproof heat dissipation distribution box, in particular to a rainproof heat dissipation distribution box and a use method, belonging to the technical field of distribution boxes. Background Art

[0002] The distribution box is an important control device of the power system. It is indispensable in industrial production, such as engineering construction, and in daily life, such as community power distribution. The distribution box usually contains a variety of electronic components such as switchgear, measuring instruments, protective electrical appliances, etc., which will generate a lot of heat during operation. If it is not discharged in time, short circuit, combustion and other hidden dangers are likely to occur.

[0003] In order to ventilate and dissipate heat, the side of the distribution box is usually designed with air inlets, heat dissipation ports and cooling fans to ventilate and dissipate heat for electrical components. However, the cooling fan in the distribution box is always in operation and cannot be turned on and off in time according to the temperature of the electrical components in the distribution box. The constant operation of the cooling fan consumes a lot of electricity, resulting in a waste of resources.

[0004] Therefore, there is an urgent need for an improved rainproof heat dissipation distribution box and a method of use to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a rainproof heat dissipation distribution box and a method of using it. By setting a temperature detection and heat dissipation mechanism, the electrical components inside the distribution box body can be detected to monitor the temperature of the electrical components at all times. When the temperature is high and rapid heat dissipation is required, the heat dissipation fan can be started to draw air for rapid heat dissipation. When the temperature is normal, the heat dissipation fan is controlled to be turned off, so that the distribution box body can be naturally ventilated and heat dissipated, thereby reducing the waste of electricity resources.

[0006] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0007] A rainproof and heat-dissipating distribution box comprises a distribution box body, air inlets are provided on both sides of the distribution box body, a heat dissipation port is provided on the top of the distribution box body, a temperature detection and heat dissipation mechanism is provided on the distribution box body, the temperature detection and heat dissipation mechanism comprises a plurality of fixed blocks symmetrically fixedly mounted on the distribution box body, a heat dissipation fan installed on the air inlet is provided between two of the fixed blocks, two electric guide rails are symmetrically fixedly mounted on the inner wall of the distribution box body, support plates are fixedly mounted on the two electric guide rails, a plurality of temperature sensors are fixedly mounted on the support plates, fixed plates are fixedly mounted on both sides of the support plates, an electric telescopic rod is fixedly mounted on the fixed plates, a pressing block is fixedly mounted on the output end of the electric telescopic rod, and a press switch is fixedly mounted on one side of the heat dissipation fan.

[0009] Preferably, a groove is formed on the fixing block, a first spring is fixedly installed inside the groove, and a clamping rod is fixedly installed at one end of the first spring.

[0010] Preferably, a clamping block is fixedly mounted on the top and bottom of the heat dissipation fan, and two limiting grooves adapted to the clamping rod are formed on the clamping block, and one end of the clamping rod is arranged in an arc shape.

[0011] Preferably, a plurality of waterproof frames located on one side of the air inlet are fixedly mounted on the surface of the distribution box body, the interior of the waterproof frame is configured to be curved, and a protective net is provided at one end of the waterproof frame.

[0012] Preferably, mounting plates are fixedly mounted on both ends of the protective net, and bolts threadedly connected to the waterproof frame are provided on the mounting plates.

[0013] Preferably, two support blocks are fixedly installed on the surface of the distribution box body, support rods are movably installed on the support blocks, a water collecting frame connected to the two support rods is arranged above the distribution box body, a second spring is fixedly installed on the water collecting frame and is sleeved on the support rods and connected to the support blocks, and a grille is fixedly installed on the bottom of the water collecting frame.

[0014] Preferably, guide plates are fixedly installed around the water collecting frame, and a stopper is fixedly installed on one end of the support rod.

[0015] Preferably, a pump extending to the interior of the water collecting frame is fixedly mounted on the guide plate, and a water pipe is fixedly mounted on one end of the pump.

[0016] Preferably, a method for using a rainproof heat dissipation distribution box comprises the following steps:

[0017] S1. When the distribution box body is running, multiple temperature sensors on the support plate are started to detect the temperature of the electrical components in the distribution box body. At the same time, two electric guide rails are started to drive the support plate to move up and down so that the temperature sensor can fully detect the temperature inside the distribution box body. When it is detected that the temperature of the electrical components at a certain height inside the distribution box body is too high, the temperature sensor controls the electric telescopic rod to start and extend it to drive the pressing block to touch the pressing switch on the cooling fan so that the cooling fan at the same position is started to draw air for heat dissipation;

[0018] S2. When the temperature sensor detects that the temperature of the electrical components inside the distribution box body tends to be normal, the electric telescopic rod is controlled again to drive the pressing block to touch the pressing switch to turn off the cooling fan to reduce the power consumption, so that the outside air can naturally pass through the air inlet and the heat dissipation port to dissipate the heat inside the distribution box body;

The water collecting frame drops under the weight of the accumulated rainwater until the grille at the bottom contacts the distribution box body to cover the heat dissipation port, so as to reduce the height of the heat dissipation port exposed to the outside. Under the protection of the grille, rainwater is prevented from entering the inside of the distribution box body through the heat dissipation port. At the same time, the two sides of the waterproof frame are set to be inclined and the inside is set to be curved, which can resist rainwater and prevent rainwater from entering the inside of the distribution box body through the air inlet;

[0020] S4. When the rain stops, multiple pumps are started simultaneously to extract the rainwater in the water collecting frame and discharge it outward through the water pipe, so as to reduce the weight of the water collecting frame and make the second spring rebound to drive it to rise, exposing the heat dissipation port for heat dissipation.

[0021] The present invention has at least the following beneficial effects:

[0022] By setting up the temperature detection and heat dissipation mechanism, the electrical components inside the distribution box body can be detected to monitor the temperature of the electrical components at all times. When the temperature is high and rapid heat dissipation is required, the cooling fan can be started to draw air for rapid heat dissipation. When the temperature is normal, the cooling fan is controlled to be turned off, so that the distribution box body can be naturally ventilated and cooled, thereby reducing the waste of electricity resources.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] like Figure 1-Figure 6 As shown, this embodiment provides an embodiment of a rainproof heat dissipation distribution box and a method of use.

[0033] A rainproof and heat-dissipating distribution box comprises a distribution box body 1, air inlets are provided on both sides of the distribution box body 1, a heat dissipation port 2 is provided on the top of the distribution box body 1, a temperature detection and heat dissipation mechanism 3 is provided on the distribution box body 1, the temperature detection and heat dissipation mechanism 3 comprises a plurality of fixed blocks 4 symmetrically fixedly mounted on the distribution box body 1, a heat dissipation fan 5 installed on the air inlet is provided between two fixed blocks 4, two electric guide rails 6 are symmetrically fixedly mounted on the inner wall of the distribution box body 1, support plates 7 are fixedly mounted on the two electric guide rails 6, a plurality of temperature sensors 8 are fixedly mounted on the support plates 7, fixed plates 9 are fixedly mounted on both sides of the support plates 7, an electric telescopic rod 10 is fixedly mounted on the fixed plates 9, a pressing block 11 is fixedly mounted on the output end of the electric telescopic rod 10, and a pressing switch 12 is fixedly mounted on one side of the heat dissipation fan 5. By setting up the temperature detection and heat dissipation mechanism 3, the electrical components inside the distribution box body 1 can be detected to monitor the temperature of the electrical components at all times. When the temperature is high and rapid heat dissipation is required, the heat dissipation fan 5 can be started to draw air for rapid heat dissipation. When the temperature is normal, the heat dissipation fan 5 is controlled to be turned off, so that the distribution box body 1 can be naturally ventilated and dissipated, thereby reducing the waste of electricity resources.

[0034] In this embodiment, Figure 1-Figure 6 As shown, fixing rods 13 are fixedly installed on both sides of the fixing plate 9, and an infrared position sensor 14 is fixedly installed on one end of the fixing rod 13. A support frame 15 is fixedly installed on the surface of the heat dissipation fan 5, and infrared sensing blocks 16 used in conjunction with the infrared position sensor 14 are fixedly installed on both ends of the support frame 15. A groove 17 is provided on the fixing block 4, and a first spring 18 is fixedly installed inside the groove 17, and a clamping rod 19 is fixedly installed on one end of the first spring 18. A clamping block 20 is fixedly installed on the top and bottom of the heat dissipation fan 5, and two limit grooves compatible with the clamping rod 19 are provided on the clamping block 20, and one end of the clamping rod 19 is set to be arc-shaped. By setting the fixing rod 13, the infrared position sensor 14, the support frame 15 and the infrared sensing block 16, and relying on the sensor detection between the infrared position sensor 14 and the infrared sensing block 16, it can be ensured that the pressing block 11 can be accurately docked with the pressing switch 12, so that the temperature sensor 8 can accurately control the heat dissipation fan 5 at the same height to start heat dissipation. By setting the groove 17, the first spring 18, the clamping rod 19 and the clamping block 20, the clamping rod 19 and the limiting grooves on the clamping block 20 are engaged to fix the heat dissipation fan 5 between the two fixed blocks 4. Under the action of the engaging support, the heat dissipation fan 5 can be prevented from falling off from the air inlet. At the same time, due to the fact that one end of the clamping rod 19 is arc-shaped and the other end is supported by the first spring 18, the clamping block 20 can squeeze and contract the clamping rod 19 to separate it, so that the heat dissipation fan 5 can be easily disassembled from the air inlet, which is convenient for repair or replacement in case of failure.

[0035] In this embodiment, Figure 1-Figure 6As shown, a plurality of waterproof frames 21 located on one side of the air inlet are fixedly installed on the surface of the distribution box body 1, the interior of the waterproof frame 21 is arranged in a curved shape, a protective net 22 is arranged at one end of the waterproof frame 21, mounting plates 23 are fixedly installed at both ends of the protective net 22, and bolts 24 threadedly connected to the waterproof frame 21 are arranged on the mounting plate 23, two support blocks 25 are fixedly installed on the surface of the distribution box body 1, support rods 26 are movably installed on the support blocks 25, a water collecting frame 27 connected to the two support rods 26 is arranged above the distribution box body 1, a second spring 28 mounted on the support rods 26 and connected to the support block 25 is fixedly installed on the water collecting frame 27, and a grille 29 is fixedly installed at the bottom of the water collecting frame 27. By setting the waterproof frame 21 and the protective net 22, the waterproof frame 21 is set on one side of the air inlet. Due to the influence of the inclination and internal curvature of the waterproof frame 21, it can effectively block the rain from the outside and prevent the rain from entering the inside of the distribution box body 1 through the air inlet. The setting of the protective net 22 can block dust and foreign matter and prevent the inside of the distribution box body 1 from being contaminated by impurities. By setting the mounting plate 23 and the bolts 24, the bolts 24 are used to install the protective net 22 on the waterproof frame 21, which can not only make its installation more convenient, but also can effectively prevent the rain from entering the distribution box body 1 through the air inlet. It is strong and easy to disassemble and replace. Through the arrangement of the support block 25, the support rod 26, the water collecting frame 27, the second spring 28 and the grille 29, on rainy days, rainwater falls and accumulates in the water collecting frame 27. The water collecting frame 27 is affected by the weight of the accumulated rainwater and drops until the grille 29 at the bottom contacts the distribution box body 1 to cover the heat dissipation port 2, so as to reduce the height of the heat dissipation port 2 exposed to the outside, and under the protection of the grille 29, rainwater is prevented from entering the interior of the distribution box body 1 through the heat dissipation port 2, thereby further achieving a waterproof effect.

[0036] In this embodiment, Figure 1-Figure 6 As shown, guide plates 30 are fixedly installed around the water collecting frame 27, a stopper 31 is fixedly installed on one end of the support rod 26, a pump 32 extending to the inside of the water collecting frame 27 is fixedly installed on the guide plate 30, and a water pipe 33 is fixedly installed on one end of the pump 32. By setting the guide plate 30 and the block 31, the rainwater in the water collecting frame 27 will overflow when it is full, and the guide plate 30 can lead the overflowing rainwater to the outside to prevent the rainwater from vertically falling along the edge of the water collecting frame 27, so that the falling rainwater is away from the distribution box body 1, and the setting of the pump 32 can limit the support rod 26 to prevent the support rod 26 from being separated from the support block 25 due to the rebound of the second spring 28. By setting the pump 32 and the water pipe 33, multiple pumps 32 are started to extract the rainwater in the water collecting frame 27 and discharge it outward through the water pipe 33, so as to reduce the weight of the water collecting frame 27 so that the rebound of the second spring 28 drives it to rise, exposing the heat dissipation port 2 for convenient heat dissipation.

[0037] In this embodiment, if Figure 1-Figure 6As shown, the working process of a rainproof heat dissipation distribution box and a method of using the present embodiment is as follows:

[0038] Step 1: When the distribution box body 1 is running, the multiple temperature sensors 8 on the support plate 7 are started to detect the temperature of the electrical components in the distribution box body 1. At the same time, the two electric guide rails 6 are started to drive the support plate 7 to move up and down so that the temperature sensor 8 can fully detect the temperature inside the distribution box body 1. When it is detected that the temperature of the electrical components at a certain height inside the distribution box body 1 is too high, the temperature sensor 8 controls the electric telescopic rod 10 to start and extend it to drive the pressing block 11 to touch the pressing switch 12 on the cooling fan 5 so that the cooling fan 5 at the same position is started to draw air for heat dissipation;

[0039] Step 2: When the temperature sensor 8 detects that the temperature of the electrical components inside the distribution box body 1 is normal, the electric telescopic rod 10 is controlled again to drive the pressing block 11 to touch the pressing switch 12 to turn off the cooling fan 5 to reduce the power consumption, so that the outside air can naturally pass through the air inlet and the heat dissipation port 2 to dissipate the heat inside the distribution box body 1;

[0040] Step 3, on rainy days, rainwater falls and accumulates in the water collecting frame 27, and the water collecting frame 27 is affected by the weight of the accumulated rainwater and falls until the grille 29 at the bottom contacts the distribution box body 1 to cover the heat dissipation port 2, so as to reduce the height of the heat dissipation port 2 exposed to the outside, and under the protection of the grille 29, rainwater is prevented from entering the inside of the distribution box body 1 through the heat dissipation port 2. At the same time, the two sides of the waterproof frame 21 are set to be inclined and the inside is set to be curved, so as to resist rainwater and prevent rainwater from entering the inside of the distribution box body 1 through the air inlet;

[0041] Step 4. When the rain stops, start multiple pumps 32 at the same time to extract rainwater from the water collecting frame 27 and discharge it outward through the water pipe 33 to reduce the weight of the water collecting frame 27 so that the second spring 28 rebounds and drives it to rise, exposing the heat dissipation port 2 for easy heat dissipation.

[0042] In summary, in this embodiment, according to a rainproof heat dissipation distribution box and a method of use of this embodiment, by setting the fixing rod 13, the infrared position sensor 14, the support frame 15 and the infrared sensing block 16, relying on the sensing detection between the infrared position sensor 14 and the infrared sensing block 16, it can ensure that the pressing block 11 can be accurately docked with the pressing switch 12, so that the temperature sensor 8 can accurately control the heat dissipation fan 5 at the same height to start heat dissipation, and by setting the groove 17, the first spring 18, the clamping rod 19 and the clamping block 20, the clamping rod 19 and the limit groove on the clamping block 20 are engaged to fix the heat dissipation fan 5 between the two fixing blocks 4, and the heat dissipation can be prevented under the action of the clamping support. The fan 5 falls off from the air inlet. At the same time, due to the fact that one end of the clamping rod 19 is arc-shaped and the other end is supported by the first spring 18, the clamping block 20 can squeeze and contract the clamping rod 19 to separate it, so that the heat dissipation fan 5 can be easily disassembled from the air inlet, which is convenient for maintenance or replacement in case of failure. Through the arrangement of the waterproof frame 21 and the protective net 22, the waterproof frame 21 is arranged on one side of the air inlet. Due to the influence of the inclination and internal bending of the waterproof frame 21, it can effectively block the rainwater from the outside and prevent the rainwater from entering the inside of the distribution box body 1 through the air inlet. The arrangement of the protective net 22 can block dust and foreign matter and prevent the inside of the distribution box body 1 from being contaminated by impurities. By installing The plate 23 and the bolt 24 are arranged, and the bolt 24 is used to install the protective net 22 on the waterproof frame 21, which can not only make the installation more firm, but also facilitate disassembly and replacement. Through the arrangement of the support block 25, the support rod 26, the water collecting frame 27, the second spring 28 and the grille 29, on rainy days, rainwater falls and accumulates in the water collecting frame 27, and the water collecting frame 27 is affected by the weight of the accumulated rainwater and falls until the grille 29 at the bottom contacts the distribution box body 1 to cover the heat dissipation port 2, so as to reduce the height of the heat dissipation port 2 exposed to the outside, and under the protection of the grille 29, rainwater is prevented from entering the interior of the distribution box body 1 through the heat dissipation port 2, which further plays a waterproof effect. With the arrangement of the plate 30 and the block 31, when the water in the water collecting frame 27 is full, it will overflow, and the guide plate 30 can lead the overflowing rainwater to the outside to prevent the rainwater from vertically falling along the edge of the water collecting frame 27, so that the falling rainwater is away from the distribution box body 1, and the arrangement of the pump 32 can limit the support rod 26 to prevent the support rod 26 from being separated from the support block 25 due to the rebound of the second spring 28. Through the arrangement of the pump 32 and the water pipe 33, multiple pumps 32 are started to extract the rainwater in the water collecting frame 27 and discharge it outward through the water pipe 33, so as to reduce the weight of the water collecting frame 27 and make it rise due to the rebound of the second spring 28, thereby exposing the heat dissipation port 2 for convenient heat dissipation.
