[0034] Application Overview

[0035] In an existing distribution box, when there is often sandstorm in the external environment, a lot of sand accumulates on the filter, which is easy to clog the filter and reduce the heat dissipation performance of the distribution box, and the service life of the filter is short.

[0036] Based on the above technical problems, the present application proposes a wind and sand proof distribution box, wherein the wind and sand proof distribution box has a simple structure, does not involve complicated manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the wind and sand proof distribution box provided by the present application is easy to produce and low-cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0037] Schematic diagram of wind and sand proof distribution box,

[0038] refer to Figures 2 to 5 According to any preferred embodiment of the utility model, a wind and sand proof distribution box includes a box body 10.

[0039] Specifically, in any embodiment of the present utility model, if Figure 2 and Figure 3 As shown, the box body 10 has a plurality of ventilation protrusions 101 and a receiving cavity 102 , each of the ventilation protrusions 101 has a through ventilation opening 1011 , and both ends of the ventilation opening 1011 are respectively connected to the receiving cavity 102 and the outside.

[0040] It should be noted that, in the height direction of the box body 10, the height of one end of the ventilation protrusion 101 close to the box body 10 is greater than the height of one end of the ventilation protrusion 101 away from the box body 10, and the outer edge of a cross section of the ventilation protrusion 101 is in an arc shape. By setting the outer shape of the ventilation protrusion 101 to be higher at one end than at the other end, when it rains, rainwater will slide down along the outer edge of the ventilation protrusion 101, and will not fall into the accommodating cavity 102 from the vent 1011; at the same time, the accommodating cavity 102 is still connected to the outside air, which helps to dissipate heat from the electrical components placed in the accommodating cavity 102.

[0041] However, external wind and sand are still easily blown into the accommodating chamber 102 from the vent 1011. In view of this, in any embodiment of the present invention, Figure 3 As shown, the wind and sand protection distribution box further includes a plurality of filters 20 , and a filter 20 is provided at the connection point between each vent 1011 and the accommodating chamber 102 . The filter 20 is provided to prevent external wind and sand from entering the accommodating chamber 102 .

[0042] Furthermore, in order to prevent the filter screen 20 from being blocked by long-term accumulation of wind and sand, causing the accommodating chamber 102 to no longer be connected to the outside, thereby reducing the heat dissipation performance of the wind and sand protection distribution box, in any embodiment of the utility model, Figure 3As shown, a power supply (not marked in the figure) is provided in the box body 10, and the anti-wind and sand distribution box also includes a plurality of cleaning components 30, and the cleaning components 30 correspond to the filter screen 20 one by one, and each of the cleaning components 30 includes a cleaning piece 301 and a linear drive device 302, and the linear drive device 302 includes but is not limited to an electric push rod. The linear drive device 302 is installed on the box body 10, and the rod body of the cleaning piece 301 is connected to the push rod of the linear drive device 302, and the connection method includes but is not limited to welding or threaded connection. When the linear drive device 302 is working, the bristles of the cleaning piece 301 reciprocate to clean the filter screen 20, and the linear drive device 302 is connected to the power supply circuit, and its circuit connection method is further implemented as a series connection, and the power supply is used to provide a power source for the linear drive device 302.

[0043] Furthermore, in order to realize the selective power supply of the linear drive device 302, in any embodiment of the present utility model, Figure 3 and Figure 4 As shown, the wind and sand protection distribution box also includes a trigger device 40, and the trigger device 40 includes a normally open switch 401. The normally open switch 401 is circuit-connected to the linear drive device 302. More specifically, the normally open switch 401 is located between the power supply and the linear drive device 302, and the normally open switch 401 is connected in series with the power supply and the linear drive device 302. When the normally open switch 401 is closed, the linear drive device 302 is powered and works. Under normal circumstances, because the normally open switch 401 is in a disconnected state, the linear drive device 302 does not work.

[0044] It should be noted that since the anti-wind and sand distribution box is mostly installed outdoors, how to enable the linear drive device 302 to work and clean the filter 20 in windy and sandy weather to prevent excessive accumulation of external wind and sand and clogging the filter 20 is a technical problem to be solved.

[0045] To solve the above problems, in any embodiment of the present invention, Figure 3 As shown, the trigger device 40 also includes a collection box 402, and the collection box 402 has a temporary storage chamber with an opening (not marked in the figure). When the external wind and sand are placed at a predetermined height in the temporary storage chamber, the normally open switch 401 is closed and the linear drive device 302 is energized to clean the filter 20, thereby extending the service life of the filter 20 and effectively filtering the external wind and sand.

[0046] Specifically, in order to realize that after the external wind and sand are placed in the temporary storage chamber and piled up to a predetermined height, the normally open switch 401 is closed and the linear drive device 302 is powered, in any embodiment of the utility model, Figure 3 and Figure 4 As shown, the trigger device 40 also includes a lifting member 403, which is slidably disposed in the temporary storage chamber, and the lifting member 403 divides the temporary storage chamber into a collection chamber 4021 and a trigger chamber 4022, the collection chamber 4021 is located above the trigger chamber 4022, and the normally open switch 401 is located below the lifting member 403 and is disposed in the trigger chamber 4022.

[0047] It should be noted that the lifting member 403 is normally located above the normally open switch 401. When external sand falls into the collecting chamber 4021, it will accumulate on the lifting member 403 and apply a downward pressure to the lifting member 403. After the external sand accumulates to a predetermined height in the collecting chamber 4021, the pressure applied by the accumulated sand to the lifting member 403 will cause the lifting member 403 to contact the normally open switch 401, close the normally open switch 401, and enable the linear drive device 302 to be powered on, and the cleaning member 301 to clean the filter 20.

[0048] Specifically, in order to realize that the lifting member 403 is normally located above the normally open switch 401, in any embodiment of the present utility model, Figure 4 As shown, the trigger device 40 further includes a plurality of elastic members 404 , wherein the elastic members 404 are springs, and two ends of the elastic members 404 are respectively connected to the lifting member 403 and the cavity wall of the trigger cavity 4022 .

[0049] In addition, in order to realize that the linear drive device 302 is powered off after the outside weather is clear, in any embodiment of the present utility model, Figure 4 As shown, the lifting member 403 has a concave cavity 4031 on one side close to the collecting chamber 4021, the bottom of the concave cavity 4031 is a conical surface or an arc surface, and the lifting member 403 also includes a plurality of discharge ports 4032, the two ends of which are respectively connected to the lowest point of the bottom of the concave cavity 4031 and the outside.

[0050] It should be noted that when the external wind and sand are very strong, the amount of wind and sand falling into the collecting chamber 4021 is greater than the wind and sand discharged from the discharge port 4032. Therefore, after a predetermined time, the lifting member 403 will contact the normally open switch 401 and activate the linear drive device 302; when the external wind and sand stop, the wind and sand accumulated in the collecting chamber 4021 will still cause the normally open switch 401 to work a predetermined distance, until the sum of the weight of the wind and sand accumulated in the collecting chamber 4021 and the deadweight of the lifting member 403 is less than the elastic force generated by the elastic member 404 to restore the deformation, the lifting member 403 moves upward a predetermined distance and makes the normally open switch 401 in an off state. At this time, the linear drive device 302 is powered off and stops working. It is obvious that compared with the prior art, the utility model can automatically clean the filter according to the external wind and sand environment, and has the advantages of being suitable for application areas with a high frequency of external wind and sand days and helping to extend the service life of the filter.

[0051] It should also be pointed out that since the anti-wind and sand distribution box is set outdoors, and the weather outdoors is not only windy and sandy but also rainy. When the rain is heavy enough, the lifting member 403 will be affected by the weight of the accumulated rainwater and move downward and contact the normally open switch 401 and cause the linear drive device 302, which is what we want to avoid.

[0052] In view of this, in order to achieve the distinction between sand and water, in any embodiment of the present utility model, as Figure 3 and Figure 4 As shown, the trigger device 40 also includes a floating member 405 and a normally closed switch 406. The normally open switch 401 is connected in series with the normally closed switch 406. When the normally closed switch 406 is disconnected, even if the normally open switch 401 is in a closed state, the linear drive device 302 will not be powered. The floating member 405 is placed in the concave cavity 4031, and the normally closed switch 406 is arranged in the collecting cavity 4021 and located above the floating member 405.

[0053] It should be noted that when external sand falls into the collecting chamber 4021, the sand will press on the floating member 405, and the floating member 405 will not contact the normally closed switch 406. Then, after the sand accumulates to a predetermined weight, the lifting member 403 moves downward and makes the normally open switch 401 closed. At this time, the circuit loop of the linear drive device 302 where the power supply, the normally open switch 401, and the normally closed switch 406 are connected in series is in a conducting state, and the linear drive device 302 works; when it is raining outside, the lifting member 403 moves downward under pressure, and the floating member 405 rises with the rise of water, and at a certain moment the floating member 405 contacts the normally closed switch 406 and makes the normally closed switch 406 disconnected, then the circuit loop where the linear drive device 302 is in a disconnected state, and the linear drive device 302 does not work.

[0054] Furthermore, in order to prevent the wind and sand accumulated in the collection chamber 4021 from accumulating to a predetermined height and disconnecting the normally open switch 401, in any embodiment of the present utility model, Figure 3 As shown, the cavity wall of the collecting cavity 4021 has a plurality of discharge holes 4023, and the distance between the discharge hole 4023 and the normally closed switch 406 is smaller than the height of the floating member 405. The sum of the unit time flow rates of each of the discharge holes 4023 is larger than the unit time flow rate of the cavity mouth of the collecting cavity 4021. Therefore, when the wind sand or rainwater accumulates to the height of the discharge hole 4023, it will be discharged along the discharge hole 4023. Because the distance between the discharge hole 4023 and the normally closed switch 406 is smaller than the height of the floating member 405, the floating member 405 can still contact the normally closed switch 406 after the rainwater rises.

[0055] Furthermore, in order to facilitate the sand or water to fall into the concave cavity 4031 of the lifting member 403, in any embodiment of the present utility model, Figure 4 As shown, the end of the floating member 405 away from the lifting member 403 has a conical surface 4051, and the outer edge of the floating member 405 has a plurality of notches 4052.

[0056] Furthermore, in order to achieve communication between the outlet 4032 and the outside, in any embodiment of the present utility model, Figure 4 As shown, the trigger device 40 also includes a plurality of pipe fittings 407, and the pipe fittings 407 correspond to the discharge outlet 4032 one by one. One end of each of the pipe fittings 407 is connected to the discharge outlet 4032, and the other end of each of the pipe fittings 407 is slidably disposed on the collection box 402 and extends out of the box body 10 of the collection box 402 by a predetermined distance to achieve communication with the outside.

[0057] Further, in any embodiment of the present invention, if Figure 3 As shown, there is a sand falling channel 103 between the filter screen 20 and the vent 1011 , and the cleaning member 301 is liftably disposed in the sand falling channel 103 .

[0058] Specifically, in the first embodiment of the present utility model, as Figure 3 As shown, the anti-wind and sand distribution box also includes a sand storage box 50, which has a sand inlet (not marked in the figure), and the sand inlet is connected to the sand falling channel 103. The wind and sand swept down from the filter 20 will fall into the sand storage box 50 along the sand falling channel 103, and will be regularly replaced by maintenance personnel after accumulating to a predetermined height.

[0059] Figure 5 The figure shows a second embodiment of the utility model. In the second embodiment, a sand guide 60 is provided between the filter 20 and the vent 1011. The box body 10 also has a tapered hole 104 connected to the outside. The sand guide 60 is arranged obliquely and forms a sand guide channel 105 with the box body 10. The two ends of the sand guide channel 105 are respectively connected to the sand falling channel 103 and the tapered hole 104. At this time, the swept sand will be discharged from the tapered hole 104 along the sand guide channel 105 to the outside.

[0060] In summary, the wind and sand proof distribution box based on the embodiment of the present application is explained, which provides the advantages of being suitable for application areas with a high frequency of external sandstorms and helping to extend the service life of the filter, etc.

[0061] It is worth mentioning that in the embodiment of the present application, the wind and sand proof distribution box has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the wind and sand proof distribution box provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
