Description

Technical Field

[0001] This invention relates to the field of cleaning device technology, and more particularly to an axial flow cleaning device for high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear is an important piece of equipment used in power supply and distribution systems and a major component of the power transmission and distribution industry. It is widely used in various places, such as high-rise buildings, residential communities, industrial and mining enterprises, construction sites, and other places with harsh operating environments.

[0003] Dust accumulates inside high and low voltage switchgear components during long-term operation. Especially in industrial environments, dust, oil, and other pollutants can lead to poor heat dissipation, reduced insulation performance, or poor contact, causing malfunctions or even safety accidents. Traditional dust removal methods require shutdown and are difficult to cover corner areas. Furthermore, when cleaning the internal components of high and low voltage switchgear, the dust is directly discharged into the external environment, which does not meet environmental protection requirements and may pollute surrounding equipment. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing technologies, such as the need to stop the machine during cleaning and the direct discharge of dust into the external environment, which pollutes surrounding equipment. Therefore, an axial flow cleaning device for high and low voltage switchgear is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an axial flow cleaning device for high and low voltage switchgear, including a duct connected to the cabinet body. One end of the duct is connected to a housing via a first connecting pipe. The housing is connected to the cabinet body via a second connecting pipe. An axial flow fan is connected inside the duct. A filter mechanism is connected inside the housing. An open box is connected to the bottom of the housing. A collection box is provided inside the open box. A sealing plate for easy material removal is connected to the open box. The other end of the first connecting pipe is connected to a dispersing mechanism.

[0007] Preferably, the filtering mechanism includes a movable frame that is slidably connected to the housing, a filter screen that is fixedly connected to the movable frame, and a plurality of first springs that are fixedly connected to the upper end of the movable frame, with one end of each first spring fixedly connected to the upper interior of the housing.

[0008] Preferably, the dispersing mechanism includes a first vent pipe, one end of which is connected to a first connecting pipe, and the other end of which has an vent. The other end of the first vent pipe is connected to a plurality of first dispersing pipes at equal intervals along the axis, and one end of each first dispersing pipe is facing downward.

[0009] Preferably, a noise reduction mechanism is connected to the first connecting pipe. The noise reduction mechanism includes a soundproof cover, which is connected to the first connecting pipe and located outside the axial flow fan. A through hole is provided on the first connecting pipe, which communicates with the soundproof cover. A sound-absorbing pad is connected to the inner wall of the soundproof cover.

[0010] Preferably, the housing is connected to an anti-clogging mechanism, which includes a motor. The motor is fixedly connected to the housing, and a movable frame is slidably connected inside the housing. The output end of the motor extends into the housing and is fixedly connected to a reciprocating screw that drives the movable frame to move back and forth. A support member is fixedly connected to the upper end of the movable frame, and a cleaning member is fixedly connected to the upper end of the support member. The cleaning member is in contact with the bottom end of the filter screen.

[0011] Preferably, the support includes a grooved column, which is fixedly connected to the upper end of the movable frame. A movable plate is slidably connected to the grooved column. A second spring is fixedly connected to the bottom end of the movable plate. One end of the second spring is fixedly connected to the grooved column. A cleaning component is fixedly connected to the upper end of the movable plate.

[0012] Preferably, a protective box is fixedly connected to the housing, the motor is located inside the protective box, and a maintenance plate is connected to the housing.

[0013] Preferably, the housing is connected to an anti-dust-raising mechanism to prevent dust from being stirred up inside the collection box. The anti-dust-raising mechanism includes a support plate, which is fixedly connected to the housing. A liquid storage cylinder is fixedly connected to the upper end of the support plate. The liquid storage cylinder is located inside the protective box. A conduit is connected to the bottom end of the liquid storage cylinder. One end of the conduit extends into the housing. A solenoid valve is connected to the conduit.

[0014] Preferably, the housing is connected to an air-purging mechanism to prevent dust accumulation on the reciprocating screw. The air-purging mechanism includes a miniature high-pressure air pump, which is fixedly connected to the upper end of the housing. The outlet end of the miniature high-pressure air pump is connected to a third connecting pipe. One end of the third connecting pipe extends into the housing and is connected to a second dispersing pipe. The second dispersing pipe has several second air outlets evenly spaced along its length, and the second air outlets are arranged towards the reciprocating screw.

[0015] Preferably, the second dispersion tube is connected to a purging mechanism, the purging mechanism including a fourth connecting tube, one end of the fourth connecting tube being connected to the second dispersion tube, and the fourth connecting tube having a plurality of air jets evenly spaced along its length, the air jets of the air jets being directed toward the cleaning component.

[0016] The axial flow cleaning device for high and low voltage switchgear proposed in this invention has the following advantages:

[0017] 1. By circulating gas between the air duct, the first connecting pipe, the housing, the second connecting pipe and the cabinet, the gas cleans the internal parts of the cabinet during the flow. There is no need to stop the machine for cleaning, and the cleaned dust is filtered out by the filter screen and collected in the collection box. The dust will not be released into the air and will not pollute the surrounding equipment.

[0018] 2. The sound-absorbing pad is fixed by the soundproof cover. The sound-absorbing pad absorbs the noise generated by the axial flow fan, thereby reducing the noise level.

[0019] 3. The movable frame moves the grooved column, which in turn moves the movable plate. The movable plate then moves the cleaning component back and forth in the horizontal direction. During this back and forth movement, the cleaning component cleans the dust adhering to the lower surface of the filter screen, maintaining the air permeability of the filter screen and thus ensuring that the gas passes through the filter screen.

[0020] 4. By forming a water layer of a certain depth at the bottom of the collection box, the dust falling into the collection box comes into contact with the water, preventing the dust in the collection box from being stirred up during the air flow. This avoids the falling dust coming into contact with the filter screen again, thus improving the cleaning effect of the filter screen.

[0021] 5. The clean gas in the second dispersion tube is released from several second exhaust pipes. The clean gas released from the second exhaust pipes blows the reciprocating screw, so that the dust is separated from the reciprocating screw and the moving frame is prevented from getting stuck due to dust.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1: Refer to Figure 1-5An axial flow cleaning device for high and low voltage switchgear includes a duct 1 connected to a cabinet 2. One end of the duct 1 is connected to a box 4 via a first connecting pipe 3. The box 4 is connected to the cabinet 2 via a second connecting pipe 5. An axial flow fan 6 is connected inside the duct 1. A filter mechanism 7 is connected inside the box 4. An open box 8 is connected to the bottom of the box 4. A collection box 10 is provided inside the open box 8. A sealing plate 9 for easy material removal is connected to the open box 8. The other end of the first connecting pipe 3 is connected to a dispersing mechanism 11.

[0036] The filter mechanism 7 includes a movable frame 71, which is slidably connected to the housing 4. A filter screen 72 is fixedly connected to the movable frame 71. Several first springs 73 are fixedly connected to the upper end of the movable frame 71, and one end of each first spring 73 is fixedly connected to the upper end of the interior of the housing 4.

[0037] The dispersion mechanism 11 includes a first vent pipe 111, one end of which is connected to the first connecting pipe 3, and the other end of which is provided with an vent 112. The other end of the first vent pipe 111 is connected to a plurality of first dispersion pipes 113 at equal intervals along the axis, and one end of each first dispersion pipe 113 is arranged downward.

[0038] Work process:

[0039] After the axial flow fan 6 is powered on and started, it draws in the gas in the first connecting pipe 3. The first connecting pipe 3 draws in the gas in the housing 4. The housing 4 draws in the gas in the cabinet 2 through the second connecting pipe 5. The drawn gas passes through the air duct 1 and enters the first air outlet pipe 111. Part of the gas in the first air outlet pipe 111 is released from the air outlet 112, and another part of the gas is released from different first dispersion pipes 113. The gas released from the air outlet 112 and the first dispersion pipes 113 blows downward to clean the parts inside the cabinet 2. The outlets of several first dispersion pipes 113 are located at the four corners of the upper part of the cabinet 2, which can clean the parts in the corners, thereby improving the dust removal effect of the parts inside the cabinet 2.

[0040] Dust-laden gas enters the housing 4 through the second connecting pipe 5. The gas inside the housing 4 moves upward and comes into contact with the filter screen 72. The filter screen 72 filters the dust in the blowing gas. The filtered dust accumulates on the lower surface of the filter screen 72. Some of the dust falls into the collection box 10 under its own gravity. After opening the sealing plate 9, the collection box 10 can be taken out for cleaning.

[0041] After filtration, the gas is reintroduced into the first connecting pipe 3, allowing the gas to circulate between the air duct 1, the first connecting pipe 3, the housing 4, the second connecting pipe 5, and the cabinet 2. During the gas flow, the gas continuously cleans the internal parts of the cabinet 2 without requiring the machine to be stopped. In addition, the dust that is cleaned is filtered by the filter screen 72 and collected by the collection box 10, and will not be discharged into the air, thus avoiding pollution of surrounding equipment.

[0042] Example 2: A significant amount of noise will be generated after the axial flow fan 6 is started, refer to... Figure 6 As another preferred embodiment of the present invention, the difference from embodiment 1 is that a noise reduction mechanism 12 is connected to the first connecting pipe 3. The noise reduction mechanism 12 includes a soundproof cover 121, which is connected to the first connecting pipe 3 and is located on the outside of the axial flow fan 6. A through hole 122 is provided on the first connecting pipe 3, which communicates with the soundproof cover 121. A sound-absorbing pad 123 is connected to the inner wall of the soundproof cover 121. The soundproof cover 121 is located on the outside of the axial flow fan 6, and the soundproof cover 121 fixes the sound-absorbing pad 123. The sound-absorbing pad 123 absorbs the noise generated by the axial flow fan 6, thereby reducing the noise level.

[0043] Example 3: After filter screen 72 filters dust from the purge gas, the dust adheres to the filter screen 72, causing blockage and affecting the flow of the purge gas. (Refer to...) Figure 7-9 As another preferred embodiment of the present invention, the difference from embodiment 1 is that an anti-blocking mechanism 13 is connected to the housing 4. The anti-blocking mechanism 13 includes a motor 131, which is fixedly connected to the housing 4. A movable frame 132 is slidably connected inside the housing 4. The output end of the motor 131 extends into the housing 4 and is fixedly connected to a reciprocating screw 133 that drives the movable frame 132 to move back and forth. A support member 134 is fixedly connected to the upper end of the movable frame 132. A cleaning member 135 is fixedly connected to the upper end of the support member 134. The cleaning member 135 contacts the bottom end of the filter screen 72. A protective box 136 is fixedly connected to the housing 4. The motor 131 is located inside the protective box 136. A maintenance plate 137 is connected to the housing 4.

[0044] The support member 134 includes a grooved post 1341, which is fixedly connected to the upper end of the movable frame 132. A movable plate 1342 is slidably connected to the grooved post 1341. A second spring 1343 is fixedly connected to the bottom end of the movable plate 1342. One end of the second spring 1343 is fixedly connected to the grooved post 1341. A cleaning member 135 is fixedly connected to the upper end of the movable plate 1342.

[0045] The cleaning component 135 is pressed into contact with the filter screen 72. The filter screen 72 moves upward and compresses the first spring 73. The first spring 73 generates elastic force after being compressed, pushing the filter screen 72 downward, causing the filter screen 72 to press the cleaning component 135 downward. The cleaning component 135 drives the movable plate 1342 to move downward. The movable plate 1342 moves smoothly under the guidance of the groove post 1341 and compresses the second spring 1343. The second spring 1343 generates elastic force after being compressed, pushing the movable plate 1342 upward, so that the movable plate 1342 drives the cleaning component 135 to maintain close contact with the filter screen 72.

[0046] After the motor 131 is powered on and started, it drives the reciprocating screw 133 to rotate, causing the moving frame 132 to move back and forth in the horizontal direction. The moving frame 132 drives the grooved column 1341 to move, and the grooved column 1341 further drives the movable plate 1342 and the cleaning component 135 to move back and forth horizontally. During the reciprocating movement, the cleaning component 135 cleans the dust attached to the lower surface of the filter screen 72, thereby maintaining the air permeability of the filter screen 72 and ensuring that the gas can pass through smoothly.

[0047] Example 4: During the reciprocating movement of the cleaning component 135, when cleaning dust adhering to the lower surface of the filter screen 72, the dust that falls after cleaning falls into the collection box 10. The blowing air easily stirs up the dust in the collection box 10 during its flow, causing the dust to be stirred up. This stirred-up dust comes into contact with the filter screen 72, thereby reducing the cleaning effect of the filter screen 72. (Refer to...) Figure 9-10 As another preferred embodiment of the present invention, the difference from embodiment 3 is that the box 4 is connected to an anti-dust-raising mechanism 14 for preventing dust in the collection box 10 from being raised. The anti-dust-raising mechanism 14 includes a support plate 141, which is fixedly connected to the box 4. A liquid storage cylinder 142 is fixedly connected to the upper end of the support plate 141. The liquid storage cylinder 142 is located inside the protective box 136. A conduit 143 is connected to the bottom end of the liquid storage cylinder 142. One end of the conduit 143 extends into the box 4. A solenoid valve 144 is connected to the conduit 143.

[0048] After the collection box 10 is placed into the open box 8, the controller controls the solenoid valve 144 to open for a set time. The liquid in the storage cylinder 142 is introduced into the collection box 10 through the conduit 143, forming a water layer of a certain depth at the bottom of the collection box 10. The dust falling into the collection box 10 comes into contact with the water, so that the dust in the collection box 10 cannot be rolled up during the gas flow, thereby preventing the falling dust from coming into contact with the filter screen 72 again and improving the cleaning effect of the filter screen 72.

[0049] Example 5: During the reciprocating movement of the cleaning component 135, when cleaning dust adhering to the lower surface of the filter screen 72 is being swept away, the dust falls downwards after sweeping. Some of the dust falls onto the reciprocating screw 133, causing the moving frame 132 to jam during movement. (Refer to...) Figure 10-11As another preferred embodiment of the present invention, the difference from embodiment 4 is that the housing 4 is connected to an air-purifying mechanism 15 to prevent dust from accumulating on the reciprocating screw 133. The air-purifying mechanism 15 includes a miniature high-pressure air pump 151, which is fixedly connected to the upper end of the housing 4. The outlet end of the miniature high-pressure air pump 151 is connected to a third connecting pipe 152. One end of the third connecting pipe 152 extends into the housing 4 and is connected to a second dispersing pipe 153. A plurality of second air outlet pipes 154 are equally spaced along the length direction on the second dispersing pipe 153. The second air outlet pipes 154 are arranged toward the reciprocating screw 133.

[0050] After the miniature high-pressure air pump 151 is started, it releases cleaning gas. The cleaning gas is introduced into the second dispersion tube 153 through the third connecting pipe 152. The cleaning gas in the second dispersion tube 153 is released from several second air outlet pipes 154. The cleaning gas released from the second air outlet pipes 154 blows the reciprocating screw 133, so that the dust is separated from the reciprocating screw 133, and the moving frame 132 is prevented from being jammed due to dust.

[0051] Example 6: When the cleaning component 135 reciprocates and cleans the dust adhering to the lower surface of the filter screen 72, the dust adheres to the cleaning component 135, reducing the cleaning effect of the cleaning component 135. (Refer to...) Figure 11 As another preferred embodiment of the present invention, the difference from embodiment 5 is that a blowing mechanism 16 is connected to the second dispersion tube 153. The blowing mechanism 16 includes a fourth connecting tube 161. One end of the fourth connecting tube 161 is connected to the second dispersion tube 153. A plurality of air jets 162 are equally spaced along the length direction on the fourth connecting tube 161. The air jet direction of the air jets 162 is set towards the cleaning component 135.

[0052] A portion of the cleaning gas in the second dispersion tube 153 is introduced into the fourth connecting tube 161. The cleaning gas in the fourth connecting tube 161 is released from several jet nozzles 162. The gas released from the jet nozzles 162 blows and cleans the cleaning component 135, thereby improving the cleaning effect of the cleaning component 135 on the filter screen 72.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
