According to the technical scheme, the outdoor electrical equipment box comprises a box body, an air pipe, an exhaust fan, an exhaust pipe and the like; the box body is communicated and fixedly connected with an air pipe; a plurality of rectangular ventilation holes are formed in the air pipe; the air pipe is fixedly connected with an exhaust fan; and the box body is communicated and fixedly connected with an exhaust pipe. When the filter screen moves repeatedly, dust attached to the filter screen is brushed away through the bristle rods, so that no dust is attached to the portion, located in the rectangular ventilation holes, of the filter screen.

Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to an outdoor electric equipment box. Background Art

[0002] Existing electrical equipment boxes usually have heat dissipation windows on the side walls of the boxes to prevent the large amount of heat generated by the electrical components from being kept in the boxes, which would cause the internal temperature of the boxes to be too high and affect the normal operation of the electrical components. However, in areas with a lot of dust in the air, such as the northwest, the dust will enter the power cabinet through the heat dissipation windows along with the air, causing greater damage to the electrical components. To avoid the above problems, there is an existing Chinese patent: a ventilation and dustproof power cabinet (CN116598901A), which has a multi-layer dustproof net in the middle of the dustproof plate constituting the crawler, so as to intercept the dust entering from the exhaust hole of the ventilation plate, and the specific interception method is to intercept the dust through the outer dustproof plate, and then with the movement of the crawler, the inner dustproof plate rotates to the outside to continue to intercept the dust, and the outer dustproof plate rotates to the inside after cleaning and waits to be reused; However, since the outer dust shield plate and the inner dust shield plate are both located near the ventilation plate, that is, after the outside air passes through the exhaust holes provided in the ventilation plate, it still needs to pass through the outer dust shield plate and the inner dust shield plate before it can enter the box to dissipate heat for the electrical components. In this process, the outside air is doubly blocked by the outer dust shield plate and the inner dust shield plate and is difficult to enter the box. That is, the total amount of air entering the box is relatively small, and the air entering the box cannot effectively dissipate the heat inside it, which causes the temperature inside the box to still be high. Summary of the invention

The air is moved along the S-shaped flow channel formed by the cooperation of all the clappers and baffles. At the same time, the clappers and baffles cooperate with each other to interfere with and beat the air, so as to avoid strong winds. Since the air will quickly pass between the upper side of the box body and the upper side of the outer rectangular belt, if the air is still interfered and beaten by the clappers, the quickly passing air will have difficulty in making good contact with the upper side of the outer rectangular belt.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of 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.

[0018] Example 1 An outdoor electrical equipment box, such as Figure 1-4 As shown, it includes a box body 1, an air duct 2, an exhaust fan 3 and an exhaust pipe 4; the box body 1 is connected to and fixedly connected with the air duct 2; the air duct 2 is provided with a plurality of rectangular ventilation holes 2a; the air duct 2 is bolted with the exhaust fan 3 for extracting outside air into the box body 1; the box body 1 is connected to and fixedly connected with the exhaust pipe 4 for allowing the air entering the box body 1 to be discharged from the inside thereof; It also includes a long rod 5, a guide rod 6, a filter screen 7, a brush rod 8 and a power component; the box body 1 is provided with two installation chambers 2b distributed up and down; a long rod 5 is rotatably connected to each installation chamber 2b; a guide rod 6 is fixed to each installation chamber 2b; the upper long rod 5 is rolled up and fixedly connected to the filter screen 7, and the other end of the filter screen 7 passes around the upper guide rod 6 and the lower guide rod 6 in turn, and is fixedly connected to the lower long rod 5; a brush rod 8 is rotatably connected to each installation chamber 2b; the upper installation chamber 2b is provided with a rectangular through hole 1 2c for discharging the sand and dust inside it to the outside; the lower installation chamber 2b is provided with a rectangular through hole 2 2d for discharging the sand and dust inside it to the outside; the air duct 2 is connected to two power components distributed up and down, and each power component is connected to the corresponding long rod 5 and brush rod 8, and the power component is used to drive the corresponding long rod 5 and brush rod 8 to rotate.

[0019] The power assembly includes a servo motor 101, gear one 102 and gear two 103; the air duct 2 is bolted to the servo motor 101, and the output shaft of the servo motor 101 is fixedly connected to the corresponding long rod 5; the long rod 5 is fixedly connected to gear one 102; the brush rod 8 is fixedly connected to gear two 103, and gear two 103 is meshed with gear one 102.

[0020] The exhaust pipe 4 is L-shaped, and the air outlet of the exhaust pipe 4 is downwardly oriented, which is used to prevent external air from entering the interior of the box body 1 through the exhaust pipe 4.

[0021] The inner bottom of the upper mounting cavity 2b is set to an inclined state where the lowest point is located at the connection between the upper mounting cavity 2b and the rectangular through hole 2c. This setting is used to guide the sand and dust in the upper mounting cavity 2b into the rectangular through hole 2c.

[0022] The specific operation of the above-mentioned embodiment 1 is as follows: when the electrical components in the box body 1 are cooled, the exhaust fan 3 is controlled to start, and the exhaust fan 3 draws the outside air, so that the outside air enters the air duct 2 through the rectangular ventilation hole 2a, and then enters the box body 1, and finally is discharged to the outside through the exhaust pipe 4, so that the air flows in the box body 1, thereby dissipating the heat in the box body 1 through the flowing air, so as to achieve the effect of cooling the electrical components in the box body 1; When the outside air enters the air duct 2 through the rectangular ventilation holes 2a, the sand and dust in the air are intercepted by the filter 7 to prevent the sand and dust contained in the air from entering the box 1 and contacting the electrical components therein, thereby affecting the normal operation of the electrical components. During this interception process, Figure 4 As shown, first, the output shaft of the upper servo motor 101 is controlled to drive the corresponding long rod 5 to rotate counterclockwise from the front to the back, so that the upper long rod 5 unwinds the part of the filter 7 rolled up thereon, and at the same time, the output shaft of the lower servo motor 101 is controlled to drive the corresponding long rod 5 to rotate counterclockwise from the front to the back, so that the lower long rod 5 continuously rolls up the filter 7, so that the filter 7 continuously moves downward, and the part of the filter 7 in the rectangular ventilation hole 2a is continuously replaced, so that there is no sand and dust attached to the part of the filter 7 in the rectangular ventilation hole 2a; In the process of the lower long rod 5 rolling up the filter screen 7, the rotating lower long rod 5 will drive the brush rod 8 to rotate through the corresponding gear 1 102 and gear 2 103 in turn, so that the lower brush rod 8 can brush away the sand and dust attached to the filter screen 7, so that the part of the filter screen 7 rolled up on the lower long rod 5 does not have any sand and dust attached to it; When the portion of the filter screen 7 rolled up onto the upper long rod 5 is unrolled, the output shaft of the upper servo motor 101 is controlled to drive the corresponding long rod 5 to rotate clockwise, so that the upper long rod 5 rolls up the filter screen 7. At the same time, the output shaft of the lower servo motor 101 is controlled to drive the corresponding long rod 5 to rotate clockwise, so that the lower long rod 5 unrolls the portion of the filter screen 7 rolled up thereon. At the same time, in this process, since the brush rods 8, gear 1 102 and gear 2 103 on the upper and lower sides have the same function, the portion of the filter screen 7 rolled up onto the upper long rod 5 also does not have the situation where sand and dust are attached. In this way, the filter screen 7 is repeatedly moved, and the dust attached to the filter screen 7 is brushed off by the brush rod 8, so that the filter screen 7 is located in the rectangular ventilation hole 2a without dust attached, thereby avoiding the problem in the prior art that the outside air is blocked by the outer dustproof plate and the inner dustproof plate and is difficult to enter the box body 1, that is, the air entering the box body 1 cannot effectively dissipate the heat inside it; Furthermore, when the upper brush rod 8 removes the dust attached to the filter screen 7, the dust brushed off will fall to the bottom of the installation cavity 2b. At this time, since the bottom of the installation cavity 2b is set to be in an inclined state where the lowest point is located at the connection between the upper installation cavity 2b and the rectangular through hole 2c, the dust brushed off will move along the bottom of the installation cavity 2b toward the rectangular through hole 2c, and finally be discharged to the outside through the rectangular through hole 2c. Furthermore, when the lower brush rod 8 brushes away the dust attached to the filter screen 7, the brushed dust falls into the installation cavity 2b and is directly discharged to the outside through the second rectangular through hole 2d.

[0023] Example 2 On the basis of Example 1, Figure 1-3 and Figure 5-6 As shown, it also includes a transmission rod 201, a rectangular belt 202, a DC motor 203, a delivery pipe 1 204, a delivery pipe 205, a sprayer 206, a water pipe 207 and a scraping component; a detector for detecting whether wind is blowing is arranged in the air duct 2; the box body 1 is rotatably connected with four rectangularly distributed transmission rods 201; all the transmission rods 201 are commonly connected to the rectangular belt 202; the box body 1 is bolted with two DC motors 203, and the output shaft of each DC motor 203 is fixedly connected to the corresponding transmission rod 201; the box body 1 is fixedly connected with a delivery pipe 1 204, and the air inlet of the delivery pipe 1 204 is connected with the air duct 2, and the air duct 2 is connected to the air duct 2 through the delivery pipe 1 20 4 is connected to the box body 1, and the air outlet of the delivery pipe 1 204 is located between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202; the box body 1 is fixedly connected with the delivery pipe 205, the air inlet of the delivery pipe 205 is located between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202, and the air outlet of the delivery pipe 205 is located on the inner side of the rectangular belt 202; the box body 1 is bolted with a sprayer 206, and the sprayer 206 is provided with a pump; the box body 1 is fixedly connected with a water pipe 207 for conveying water into the sprayer 206, and the water pipe 207 is connected with the sprayer 206; the box body 1 is fixedly connected with a scraping component for scraping sand and dust on the rectangular belt 202, and the scraping component is in contact with the rectangular belt 202.

[0024] The scraping assembly includes a rectangular tube 208 and a scraper 209 ; the box body 1 is fixedly connected with the rectangular tube 208 ; the rectangular tube 208 is fixedly connected with the scraper 209 , and the scraper 209 is in contact with the rectangular belt 202 .

[0025] The scraper 209 is provided with two blocking parts 209 a distributed front and back, and the blocking parts 209 a are used to collect the sand and dust scraped off by the scraper 209 into the rectangular tube 208 .

[0026] It also includes a mounting plate 301, a motor 302, a mounting rod 303 and a clapper 304; a mounting plate 301 is connected to the front and rear sides of the box body 1; three motors 302 are bolted to the rear mounting plate 301; another two motors 302 are bolted to the front mounting plate 301; the rotating part of each motor 302 is fixedly connected to a mounting rod 303; each mounting rod 303 is fixedly connected to four clappers 304.

[0027] The specific operation of the above-mentioned embodiment 2 is as follows: when the wind blows, after the wind enters the rectangular ventilation hole 2a, the wind will squeeze the dust attached to the filter screen 7. Under the action of squeezing, the dust will pass through the mesh of the filter screen 7 and enter the air duct 2 together with the outside air, thereby causing the dust to still exist in the air entering the box body 1; Therefore, by setting a delivery pipe 204 with an air outlet located between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202 on the box body 1, and the air inlet of the delivery pipe 204 is connected with the air duct 2, and the air duct 2 is connected with the box body 1 through the delivery pipe 204, so that after the outside air enters the air duct 2, it will pass through the delivery pipe 204, the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202, and the delivery pipe 2 205 in sequence before contacting the electrical components. After the installation of the electrical equipment box, it is also necessary to connect the external rubber tube to the water pipe 207, and water is transported to the water pipe 207 through the external rubber tube. At the same time, the detector set in the air duct 2 detects whether the wind is blowing. The detection method is to judge whether the wind is blowing by the overall flow rate of the outside air entering the air duct 2, that is, when the wind is not blowing, the overall flow rate of the outside air entering the air duct 2 is relatively slow, and when the wind is blowing, the overall flow rate of the outside air entering the air duct 2 is relatively fast. Therefore, when the detector provided in the air duct 2 detects the start of wind, the pump provided in the sprayer 206 is first controlled to pump water into the interior through the water pipe 207, and then the water is sprayed to the right part of the upper outer side of the rectangular belt 202 through the sprayer 206. At the same time, the output shaft of the DC motor 203 is controlled to drive the rectangular belt 202 to rotate counterclockwise from the front to the back through the corresponding transmission rod 201. As the rectangular belt 202 continues to rotate, each part of the upper outer side of the rectangular belt 202 will absorb water. Therefore, when the air passes between the upper inner side of the box body 1 and the upper outer side of the rectangular belt 202, When the air contacts the upper outer side of the rectangular belt 202, since the upper outer side of the rectangular belt 202 is adsorbed with water, the sand and dust in the air will adhere to the water on the upper outer side of the rectangular belt 202, thereby removing the sand and dust in the air. As the rectangular belt 202 continues to rotate, when the sand and dust on the left outer side of the rectangular belt 202 passes through the scraper 209, the sand and dust on the left outer side of the rectangular belt 202 will be scraped off by the scraper 209, and the scraped sand and dust will move downward along the scraper 209, and then enter the rectangular tube 208, and finally be discharged to the outside through the rectangular tube 208, so that the rectangular belt 202 can circulate and remove the sand and dust in the air. In this way, the air passes between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202, and then the water is sprayed onto the rotating rectangular belt 202 by the sprayer 206, so that the water on the rectangular belt 202 can remove the sand and dust in the air, so as to avoid the problem that when the wind blows, the sand and dust attached to the filter screen 7 will pass through the mesh of the filter screen 7 under the pressure of the wind and enter the air duct 2 together with the outside air, thereby causing the problem that the air entering the box body 1 still has sand and dust; Considering that when the air passes between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202, the air does not completely contact the outer upper side of the rectangular belt 202, that is, the sand and dust in the part of the air passing near the inner upper side of the box body 1 is difficult to adhere to the water on the outer upper side of the rectangular belt 202. At the same time, when the wind blows, the wind will push the outside air into the air duct 2, that is, the air will pass between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202 relatively quickly, so there are more parts in the air that will not contact the outer upper side of the rectangular belt 202. Therefore, there is still a small amount of sand and dust in the air in this scene; Therefore, in the process of the sprayer 206 spraying water, based on the view from front to back, the rotating part of the control motor 302 drives the corresponding mounting rod 303 and its connected parts to continuously rotate clockwise and counterclockwise, thereby interfering with the air passing between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202 through the clapper 304, so that the time the air stays between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202 is increased, and during the rotation process, the clapper 304 will continuously slap the air, thereby enhancing the contact between the air and the outer upper side of the rectangular belt 202, that is, the part of the air passing near the inner upper side of the box body 1 will contact the water on the outer upper side of the rectangular belt 202, thereby avoiding the existence of a part in the air that will not contact the outer upper side of the rectangular belt 202, which will lead to the problem of a small amount of sand and dust still existing in the air.

[0028] Example 3 On the basis of Example 2, Figure 1-3 and Figure 5-8As shown, it also includes an electric push rod 401, a circular mounting frame 402, a limiting plate 403, a blocking plate 404 and a spring telescopic rod 405; two electric push rods 401 are bolted to the front and rear sides of the box body 1, and the telescopic portion of each electric push rod 401 is fixedly connected to the corresponding mounting plate 301, and each mounting plate 301 is connected to the box body 1 through the corresponding electric push rod 401; each mounting rod 303 is rotatably and slidably connected to a circular mounting frame 402, and each circular mounting frame 402 is rotatably connected to the box body 1; each circular mounting frame 402 is fixedly connected to four limiting plates 403; each clapping plate 304 is slidably connected to the blocking plate 404; each blocking plate 404 is provided with an inclined portion, and the inclined portion on each blocking plate 404 is in contact with the corresponding limiting plate 403; each clapping plate 304 is fixedly connected to three spring telescopic rods 405, and the telescopic portion of each spring telescopic rod 405 is fixedly connected to the corresponding blocking plate 404. It also includes an electric heating plate 501; the box body 1 is fixed with four electric heating plates 501 for heating the air.

[0029] It also includes an electric refrigeration pipe 502; the box body 1 is fixedly connected with the electric refrigeration pipe 502 for cooling the rectangular belt 202.

[0030] The specific operation of the above-mentioned embodiment 3 is as follows: Considering that when a strong wind blows, the strong wind will push a large amount of external air into the air duct 2, that is, the air will quickly pass between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202. At this time, if the air passing between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202 is still disturbed and beaten by the clapper 304, the air passing quickly will have difficulty in contacting the outer upper side of the rectangular belt 202, thereby resulting in a small amount of sand and dust still existing in the air in this scene; Therefore, when the detector installed in the air duct 2 detects that a strong wind is blowing, the telescopic part of the electric push rod 401 is first controlled to drive the mounting rod 303, the clapper board 304, the blocking plate 404 and the spring telescopic rod 405 to move toward the direction of the circular mounting frame 402 through the corresponding mounting plate 301 and the motor 302 in sequence, until the clapper board 304 contacts the corresponding circular mounting frame 402. In this process, since the limiting plate 403 will limit the corresponding blocking plate 404, and the inclined part on the blocking plate 404 contacts the corresponding limiting plate 403, when moving, the blocking plate 404 will move on the clapper board 304 in the direction away from the mounting rod 303 under the restriction of the corresponding limiting plate 403, and the moving blocking plate 404 will be as shown in the following figure. Figure 7 The state shown in the middle left 1 becomes as follows Figure 7In the state shown in the middle right 1, at this time, the upper blocking plate 404 will be at the inner lower edge of the box body 1, and there is a relatively small gap between the two, and the lower blocking plate 404 will be at the outer upper edge of the rectangular belt 202, and there is also a relatively small gap between the two. When the movement is completed, the clapper 304 and the blocking plate 404 on each mounting rod 303 will be as shown in the following figure. Figure 8 The state shown in the middle left 1 becomes as follows Figure 8 In the state shown in the middle right 1, at this time, the clappers 304 and the blocking plates 404 on all the mounting rods 303 cooperate to form an S-shaped flow channel between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202; Therefore, when the air passes between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202, the air is restricted by the clappers 304 and the blocking plates 404 on all the mounting rods 303, and the air moves along the S-shaped flow channel formed by the cooperation of all the clappers 304 and the blocking plates 404, so that the air stays between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202 for a longer time. At the same time, the rotating part of the control motor 302 drives the corresponding mounting rod 303 and the parts connected thereto to rotate repeatedly, so that the clappers 304 and The blocking plates 404 cooperate with each other to interfere with the air, so that the residence time of the air between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202 is further prolonged. At the same time, it also has a flapping effect, which can also enhance the contact between the air and the outer upper side of the rectangular belt 202, so as to avoid strong winds. Since the air will quickly pass between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202, if the flapper 304 is still used to interfere and flap the air, the problem that the quickly passing air is difficult to contact the outer upper side of the rectangular belt 202 well; Considering that at night, due to the temperature generated by the electrical components inside the box 1, the inner wall of the box 1 will be in a high temperature state, while the outer wall of the box 1 is in direct contact with the outside air and is in a low temperature state, and there is a lot of moisture in the outside air at night, when the outside air enters the box 1 and mixes with the hot gas inside, the moisture in the air will form a condensation reaction on the inner wall of the box 1, that is, condensed water will appear on the inner wall of the box 1, and the presence of condensed water will easily lead to safety hazards of the electrical components in the box 1. Therefore, at night, if water is still sprayed onto the rotating rectangular belt 202 by the sprayer 206 to remove dust, it will inevitably cause the moisture in the air to increase, and then cause more condensed water to appear on the inner wall of the box 1, and the risk of safety hazards of the electrical components will be greatly increased; Therefore, at night, first, the rectangular belt 202 is controlled to rotate in the same manner as described above, and the clapper 304 interferes with and claps the air passing between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202 in the same manner as described above. At this time, the electric heating plate 501 is controlled to heat the air passing between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202. At this time, since the rectangular belt 202 is in a rotating state, the electric heating plate 501 has a relatively short heating time for the outer upper side of the rectangular belt 202, that is, the temperature of the outer upper side of the rectangular belt 202 will be lower than the temperature of the heated air. When the air passes between the inner upper side of the box body 1 and the outer upper side of the rectangular belt 202, the moisture in the air will form a condensation reaction on the outer upper side of the rectangular belt 202, thereby removing the moisture in the air, so as to avoid the problem of condensation water when the air enters the box body 1 due to the presence of a large amount of moisture in the outside air at night. It should be noted that the temperature at night in areas with more dust in the air, such as the northwest, is usually around zero degrees, and the temperature of the air after being heated by the electric heating plate 501 only needs to be higher than the temperature of the upper outer side of the rectangular belt 202 for a condensation reaction to occur. Under the influence of the large amount of heat generated by the electrical components when the cabinet 1 is working, the temperature inside will be much higher than the temperature of the air after heating. Therefore, the heated air can still dissipate heat for the electrical components. When the detector set in the air duct 2 detects that wind or strong wind is blowing, since the moisture in the air has formed water on the upper outer side of the rectangular belt 202, the sprayer 206 does not need to work, and the clapper 304 and the blocking plate 404 can work in the same way as described above. In this way, if water is still sprayed onto the rotating rectangular belt 202 by the sprayer 206 at night to remove dust, it will inevitably cause the moisture in the air to increase, and then cause more condensed water to appear in the cabinet 1, and the risk of safety hazards of electrical components will be greatly increased. Furthermore, when the electric heating plate 501 is heating the air, the electric refrigeration tube 502 is controlled to operate, and the rectangular belt 202 is cooled down through the electric refrigeration tube 502, so as to avoid the problem that although the electric heating plate 501 heats the upper outer side of the rectangular belt 202 for a relatively short time, after the rectangular belt 202 absorbs heat for a long time, the temperature of the rectangular belt 202 is easily the same as the temperature of the air after heating, thereby causing the moisture in the air to be unable to condense on the upper outer side of the rectangular belt 202.
