Technical Field

[0001] The invention relates to the technical field of flanges, and in particular to a dustproof and waterproof distribution box body and a sealing structure thereof. Background Art

[0002] A distribution box is an electrical device used to distribute electricity. It is used for switching, controlling or protecting the power generation, transmission, distribution, energy conversion and consumption of power systems.

[0003] In high and low voltage power grids, distribution boxes are widely used. In many cases, the distribution boxes are directly installed outdoors. During installation, a base is built and the distribution box is installed on the base. The cables pass through the base into the distribution box to transmit power to the distribution box.

[0004] The components inside the distribution box will generate heat when in use. A heat dissipation vent is usually opened on the outside of the distribution box to circulate the air inside the distribution box. However, the heat dissipation vent will also bring dust in the air into the interior of the distribution box. When it rains, rainwater splashes and enters the interior of the distribution box through the heat dissipation vent, causing the components inside the distribution box to be corroded by dust and water, resulting in a reduction in the service life of the components inside the distribution box. Therefore, a dustproof and waterproof distribution box body and a sealing structure thereof are needed. Summary of the invention

A snap-on interface is provided on the left side of each of the four snap-on blocks, and the side wall of the protective cover is snap-on to the inside of the four snap-on blocks, so that the protective cover is limitedly mounted on the inner wall of the shell.

[0008] As a further improvement of the technical solution, a filter is installed on the top of the inner wall of the protective cover, and the filter is arranged at the bottom of the leakage hole to filter the air entering the heat dissipation port.

[0009] As a further improvement of the technical solution, two protective covers are provided, and the two protective covers are symmetrically distributed on the left and right sides of the inner wall of the shell to shield the heat dissipation ports opened on the left and right sides of the shell.

[0010] As a further improvement of the present technical solution, two collecting boxes are installed at the bottom of the inner wall of the shell. The two collecting boxes are symmetrically distributed at the bottom of the inner wall of the shell. The collecting boxes are arranged at the bottom of the water outlet to collect the water flowing out of the water outlet.

[0011] As a further improvement of the technical solution, the blowing assembly includes a shunt pipe fixedly connected to the air outlet of the fan, air outlet pipes are fixedly installed at both ends of the shunt pipe, and a plurality of air outlet holes are opened on the outer surface of the air outlet pipe.

[0019] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 6 As shown, the purpose of this embodiment is to provide a dustproof and waterproof distribution box body, including a shell 1 of the distribution box, both sides of the shell 1 are provided with heat dissipation ports 11 that penetrate into the interior of the shell 1, a baffle 12 is fixedly installed on the outside of the heat dissipation port 11, and the top of the baffle 12 is set in an arc shape to block rainwater outside the heat dissipation port 11, a clamping component 2 is installed on the right side of the inner wall of the shell 1, and a protective cover 21 is clamped inside the clamping component 2, and the protective cover 21 is installed on the right side of the inner wall of the shell 1 to cover and shield the heat dissipation port 11, and a plurality of dividing strips 22 are fixedly installed on the inner wall of the protective cover 21, a leakage hole 23 is opened on the top of the protective cover 21, and a water outlet 24 is opened on the bottom of the protective cover 21, and the leakage hole 23 and the water outlet 24 are used to guide the air and water source entering the heat dissipation port 11.

[0021] It can be seen that the heat dissipation ports 11 on both sides of the distribution box housing 1 can discharge the hot air inside the housing 1 and send the external air into the housing 1 for internal circulation. However, the air outside the housing 1 is mixed with dust and impurities. A baffle 12 is installed outside each heat dissipation port 11, so that the baffle 12 can block the dust in the air to a certain extent, and the top of the baffle 12 is set in an arc shape, which can block the vertically falling rain. However, the rain will be splashed when it is blown by the wind or falls on the ground, so that the rain avoids the block and enters the inside of the box from the inside of the heat dissipation port 11. The dust and rain that enter cause erosion to the components inside the housing 1. Therefore, a clamping assembly 2 is fixedly installed on the inner wall of the shell 1, and the clamping assembly 2 can clamp and fix the protective cover 21 to the inner wall of the shell 1. The protective cover 21 is installed on the side of the heat dissipation port 11 to block rainwater and air entering the heat dissipation port 11. A plurality of dividing strips 22 are fixed on the inner wall of the protective cover 21 to separate the incoming air. A leakage hole 23 and a water outlet 24 are respectively provided on the top and bottom of the protective cover 21, so that the air entering the protective cover 21 rises and flows out from the leakage hole 23, and the entering rainwater falls from the water outlet 24 due to its own gravity and is collected by the collecting box 5. A filter net 4 is installed at the internal leakage hole 23 of the protective cover 21 to filter the air entering the shell 1, and the hot air inside the shell 1 can be dispersed from the leakage hole 23 and the water outlet 24, so as to achieve the effect of dustproofing the distribution box and preventing rainwater from splashing onto the device for waterproofing.

[0022] A support frame 3 is installed at the bottom of the inner wall of the shell 1 , a fan 31 is installed on the top of the support frame 3 , and a blowing assembly 32 is installed at the air outlet of the fan 31 . The blowing assembly 32 is used to gather dust inside the shell 1 .

[0023] Since the distribution box is opened and closed or located outdoors for a long time, dust will still adhere to the inside of the shell 1 and enter the shell and adhere to the components. Over a long period of time, it may cause heating at the connection of the components. By installing a support frame 3 at the bottom of the box and fixing the fan 31, the fan 31 can blow off the dust on the components inside the shell 1 through the connected blowing assembly 32, thereby achieving the effect of dust-proofing the components inside the distribution box.

[0024] It should be noted that the fan 31 is a small fan 31, and the internal circuit connection and structure of the fan 31 are prior art, and its working principle is common knowledge to those skilled in the art, and will not be described in detail here.

[0025] First of all, considering the problem of how to install and prevent dust from the protective cover 21, Figure 2-Figure 5 , the specific structure of the snap-in assembly 2 is disclosed. The snap-in assembly 2 includes a snap-in block 201 fixedly mounted on the right side of the inner wall of the shell 1. There are four snap-in blocks 201. The left sides of the four snap-in blocks 201 are all provided with snap interfaces 202. The side wall of the protective cover 21 is snap-into the inside of the four snap-in blocks 201, and the protective cover 21 is limitedly mounted on the inner wall of the shell 1. A filter screen 4 is installed on the top of the inner wall of the protective cover 21. The filter screen 4 is arranged at the bottom of the leak hole 23 to filter the air entering the heat dissipation port 11. There are two protective covers 21, which are symmetrically distributed on the left and right sides of the inner wall of the shell 1 to shield the heat dissipation ports 11 opened on the left and right sides of the shell 1.

[0026] By fixing four snap-in blocks 201 with a spacing matching the side wall of the protective cover 21 on the inner wall of the shell 1, the protective cover 21 can be snapped into the snap-in interface 202 opened on the side of the snap-in block 201, and then the snap-in block 201 and the side wall of the protective cover 21 are threadedly connected together by bolts, and the protective cover 21 is installed on the side of the heat dissipation port 11. The air outside the shell 1 enters the inside of the protective cover 21 from the heat dissipation port 11, and the air flows upward and is diverted by the partition plate installed inside the protective cover 21, and enters the inside of the shell 1 from the leakage hole 23. The partition plate can speed up the efficiency of air circulation, and the filter net 4 installed at the bottom of the leakage hole 23 inside the protective cover 21 can filter the incoming air and filter the dust in the air to prevent the external dust from entering the inside of the shell 1, thereby achieving the effect of dustproofing the distribution box.

[0027] Secondly, considering the problem of how to deal with the rainwater splashed from the heat dissipation port 11 into the housing 1, the following is shown. Figure 3-Figure 5 Two collecting boxes 5 are installed at the bottom of the inner wall of the shell 1. The two collecting boxes 5 are symmetrically distributed at the bottom of the inner wall of the shell 1. The collecting boxes 5 are arranged at the bottom of the water outlet 24 to collect the water flowing out of the water outlet 24.

[0028] When it rains, the splashed rainwater enters the protective cover 21 from the heat dissipation port 11, is blocked by the protective cover 21, flows down from the water outlet 24 along the inner wall of the protective cover 21, and is received by the collecting groove arranged at the bottom of the inner wall of the shell 1. Some desiccant can be placed inside the collecting groove to absorb the flowing rainwater, so as to prevent the rainwater from affecting the devices inside the shell 1 and achieve the effect of waterproofing the distribution box.

[0029] It should be noted that the desiccant is preferably a silica gel desiccant, and its working principle is common knowledge to those skilled in the art and will not be described in detail here.

[0030] Finally, considering how the blowing assembly 32 blows away the dust on the components inside the housing 1, the following example is presented. Figure 2 and Figure 6 , the specific structure of the blowing assembly 32 is disclosed, the blowing assembly 32 includes a shunt pipe 301 fixedly connected to the air outlet of the fan 31, and an air outlet pipe 302 is fixedly installed at both ends of the shunt pipe 301, and a plurality of air outlet holes 303 are opened on the outer surface of the air outlet pipe 302. One side of the air outlet pipe 302 is fixedly installed on the right side of the inner wall of the shell 1, and the air outlet pipe 302 is installed on the inner wall of the shell 1.

[0031] By fixing the two air outlet pipes 302 to the inner wall of the housing 1, the side bottom ends of the two air outlet pipes 302 can be connected to the shunt pipe 301, and the fan 31 is powered on to ventilate the connected shunt pipe 301 and the air outlet pipe 302, so that the wind flow is blown out from the air outlet holes 303 of the air outlet pipe 302. The air outlet holes 303 are vertically linearly distributed outside the air outlet pipe 302, and the outer surface of the device installed inside the housing 1 can be blown to blow the dust adhering to the device to the other side of the housing 1, so that the dust falls into the collection groove below the bottom wall of the housing 1, and the dust falls into the collection box 5, which cannot be blown by the wind flow, so that the dust is collected in the collection box 5 for unified treatment. In addition, the blowing airflow can accelerate the air circulation inside the housing 1 and dissipate the heat of the device in the housing 1.

[0032] It should be noted that the fan 31 is controlled by a control component, and the dust in the housing 1 can be collected and the device can be cooled down by only setting the start-up time interval.

[0033] Embodiment 2: Considering the sealing condition of the wire opening 61 at the bottom of the distribution box housing 1, Figure 1 The present invention also provides a dustproof and waterproof distribution box sealing structure, which also includes a bottom plate 6, which is fixedly installed on the bottom of the inner wall of the shell 1, and a wire opening 61 is opened on the top of the bottom plate 6. A conical sealing sleeve 62 is fixedly installed on the top of the wire opening 61, and two collection boxes 5 are arranged on both sides of the bottom plate 6.

[0034] By installing a conical sealing sleeve 62 on the top of the wire passing port 61, the sealing sleeve 62 is made of rubber material, so that when the cable enters the shell 1 from the wire passing port 61, it is wrapped by the sealing sleeve 62, which can effectively reduce the entry of water vapor and dust into the interior of the shell 1 through the wire passing port, enhance the dustproof and waterproof effect of the protective cover 21, and thereby achieve the effect of sealing the shell 1.

[0035] In summary, the working principle of this solution is as follows: When the distribution box is installed and used, the components installed inside the housing 1 will generate heat during operation. The heat dissipation port 11 can be used to circulate the outside air with the air inside the housing 1. The outside air enters the protective cover 21 from the heat dissipation port 11, and passes through the filter 4 installed on the top of the inner wall of the protective cover 21 to filter the dust in the air. The filtered air enters the inside of the housing 1 from the leak hole 23, and is converted into the hot air in the housing 1, so as to achieve the effect of heat dissipation and dust prevention for the components inside the housing 1. On rainy days, the distribution box is installed outdoors, and rainwater splashes down, making it impossible for the blocker to block it. Rainwater enters the protective cover 21 from the heat dissipation port 11, flows down from the water outlet 24 at the bottom along the inner wall of the protective cover 21, and falls into the collection box 5 at the bottom of the water outlet 24 for collection. A desiccant is placed in the collection box 5 to absorb the falling rainwater, and the desiccant can absorb the moisture in the housing 1, so as to achieve the effect of waterproofing the distribution box. The distribution box cannot be completely sealed, and it is necessary to open and close the distribution box frequently for inspection, which will cause dust to adhere to the outside of the device, affecting the normal operation of the device for a long time. By energizing the fan 31, the fan 31 transports the airflow from the shunt pipe 301 to the inside of the air outlet pipe 302, and the multiple air outlet holes 303 opened on the air outlet pipe 302 blow air to the devices inside the shell 1, which can blow off the dust on the devices and make the dust fall into a collection groove below the bottom wall of the shell 1 for collection, gather and collect the dust for unified treatment, and prevent the devices in the shell 1 from dust. The airflow blown out by the air outlet pipe 302 can also speed up the air circulation inside and outside the shell 1, reduce the temperature inside the shell 1, and achieve the effect of heat dissipation.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
