Description

Technical Field

[0001] This invention relates to the field of switchgear protection technology, specifically to an anti-condensation switchgear. Background Technology

[0002] Condensation is the phenomenon of water vapor in the air condensing into liquid water when it encounters cold air. Anti-condensation switch cabinets mainly reduce condensation by controlling the temperature and humidity inside the cabinet and preventing the surface temperature inside the cabinet from falling below the dew point temperature. Some existing equipment uses ventilation fans to exhaust the humid air inside the cabinet and introduce dry air from the outside, thereby reducing the generation of water vapor in the air inside the cabinet and achieving the effect of preventing condensation. When the equipment is in a high-humidity external environment, the ventilation system will draw high-humidity air from the outside into the switch cabinet, causing the humidity inside the cabinet to accumulate and increase continuously, which will aggravate condensation and cause a significant decrease in insulation resistance, resulting in a continuous decline in the insulation protection capability of the equipment.

[0007] Preferably, the fixing component includes a fixing block fixedly connected to the outer wall of the switch cabinet, an exhaust fan fixedly connected to the outer wall of the fixing block, and a ventilation filter fixedly connected to the outer wall of the fixing block. The fixing block is located on the outside of the switch cabinet, while the ventilation fan is located inside the switch cabinet.

[0008] Preferably, the rotating assembly includes a rotating ring rotatably connected to the inner wall of the fixed block, a plurality of balls rotatably connected to the outer wall of the rotating ring, and two ball grooves formed on the outer wall of the fixed block. The rotating ring is conical, with the larger opening near the ventilation filter and the smaller opening near the ventilation fan. The two ball grooves are mirrored, and there are sixteen balls arranged in groups of eight. The two groups of balls are mirrored, and each group of balls is matched with a ball groove.

[0009] Preferably, the condensing assembly includes condensing fan blades fixedly connected to the inner wall of the rotating ring, and a cooler is fixedly connected to the outer wall of the fixed block; The cooler is electrically activated, and the cooling surface contacts the outer surface of the rotating ring, thereby cooling the rotating ring and thus cooling the condenser fan blades.

[0010] Preferably, the flow-blocking assembly includes a flow-blocking ring fixedly connected to the inner wall of the rotating ring, a scraper fixedly connected to the outer wall of the flow-blocking ring, and a drainage groove provided on the inner wall of the fixed block. The baffle ring protrudes towards the rotating ring at its center, the scraper is made of hard rubber, the scraper contacts the inner surface of the rotating ring, and the drain channel leads to the outside of the switch cabinet.

[0011] Preferably, the buffer assembly includes an annular groove formed in the inner wall of the fixed block, and a Z-shaped spring piece is fixedly connected to the inner wall of the annular groove; One side of the Z-shaped spring is fixed to the fixed block, and the other side is in contact with the rotating ring.

[0012] Preferably, the diversion assembly includes a plurality of support columns fixedly connected to the outer wall of the baffle ring, and a diversion plate is fixedly connected to the outer wall of the plurality of support columns; Among them, several support columns are arranged in a mirror image, the center of the flow divider protrudes towards the rotating ring, and the outer edge of the flow divider covers the inner diameter of the baffle ring.

[0013] The present invention has the following beneficial effects: (1) When the ventilation fan is started, the present invention draws in the air outside the switch cabinet. The air first passes through the ventilation filter to block dust and large-diameter particles. The moisture in the air condenses on the surface of the condenser fan blades. The air with some moisture removed then passes over the condenser fan blades and enters the ventilation fan. The airflow blows on the surface of the condenser fan blades, thereby causing the condenser fan blades to rotate the rotating ring. At this time, the water droplets condensed on the surface of the condenser fan blades are subjected to outward centrifugal force. The water droplets move along the surface of the condenser fan blades in the direction of centrifugal force. Since the rotating ring is set in a conical shape, the water droplets move on the surface of the rotating ring towards the larger diameter of the rotating ring, that is, towards the outside of the switch cabinet, so that the water droplets can flow to the outside. Through the application of the above components, the ventilation system will draw in the high humidity air from the outside into the switch cabinet when the equipment is in a high humidity external working condition, which will cause the humidity of the air inside the cabinet to accumulate and increase continuously, thereby aggravating the condensation phenomenon, causing a significant decrease in insulation resistance, and causing the insulation protection capability of the equipment to continuously decrease.

[0014] (2) The present invention utilizes the characteristic of the rotating ring of the above-mentioned device to drive water droplets to move in the direction of centrifugal force. When the water droplets on the condenser fan blades rotate, some water droplets splash to the rear side of the condenser fan blades. Under the obstruction of the baffle ring, the water droplets are left on the side of the baffle ring close to the rotating ring. By setting a scraper, the scraper is set at an angle along the rotation direction of the rotating ring, thereby suppressing the tendency of water droplets to move towards the side of the larger diameter of the rotating ring. The scraper pushes the accumulated water droplets into the drain trough, so that the water droplets can be discharged from the outside of the switch cabinet through the drain trough. Through the application of the above components, the problem of water accumulation in the switch cabinet is effectively reduced due to the influence of the rotation of the rotating ring on some of the condensed water droplets being thrown into the switch cabinet.

[0015] (3) This invention utilizes the characteristic of the rotating ring of the above-mentioned device. The rotating ring is conical, and when the rotating ring rotates, it generates an axial force towards the side with the larger diameter, such as... Figure 9 As shown, the Z-shaped spring contacts the rotating ring on the side closest to it, allowing relative sliding between them. When the rotating ring is subjected to axial force and tends to move to the left, it transitions from a free state to a compressed state. Thus, the Z-shaped spring suppresses the tendency of the rotating ring to move to the left. By applying the above components, the problem of axial force during the rotation of the rotating ring, which makes it difficult for the balls to roll and affects the rotation of the rotating ring, is effectively prevented.

[0016] (4) The present invention utilizes the characteristics of air passing through the condenser fan blades of the above-mentioned components, such as... Figure 9 As shown, because the center of the manifold protrudes towards the rotating ring, when the airflow contacts the left side of the manifold, the air diffuses outwards. Air enters the gap between the manifold and the baffle ring, flows along the baffle ring, flows along the arc-shaped side of the baffle ring towards the manifold, and then flows out through the inner diameter of the baffle ring. The airflow direction is as follows: Figure 9The flow direction of G, through the application of the above components, effectively prevents some air from flowing directly out of the baffle ring and some air from generating vortices in the arc section of the baffle ring, thus preventing a decrease in airflow efficiency.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figures 1-4 The present invention is an anti-condensation switch cabinet, including a switch cabinet body 13, wherein circuit components are disposed inside the switch cabinet body 13, and further comprising: Ventilation mechanism 1 is fixedly connected to the outer wall of the switch cabinet body 13; Condensation mechanism 2 is fixedly connected to the inner wall of ventilation mechanism 1; Auxiliary mechanism 3 is fixedly connected to the inner wall of ventilation mechanism 1; Among them, the switch cabinet 13 is combined with other cabinets, and there are two ventilation mechanisms 1. The upper ventilation mechanism 1 is used to draw in the gas inside the switch cabinet 13, and the lower ventilation mechanism 1 is used to draw in the outside air into the switch cabinet 13, thereby achieving the exchange of gas inside the switch cabinet 13. The upper ventilation mechanism 1 contains only the fixed component 11 and no other mechanisms or components, while the lower ventilation mechanism 1 contains all mechanisms and components.

[0022] Ventilation mechanism 1 includes: Fixing component 11 is fixedly connected to the outer wall of the switch cabinet body 13; Rotating component 12 is rotatably connected to the inner wall of fixed component 11; Among them, the fixed component 11 restricts the rotating component 12 from moving laterally or longitudinally; During use, the operator installs various electrical components inside the switch cabinet 13, ensures that the device is not in operation, starts the switch cabinet, and then starts the fixing component 11 to ventilate the inside of the switch cabinet 13.

[0023] Condensation mechanism 2 includes: Condensation component 21 is fixedly connected to the inner wall of fixed component 11; The flow-blocking component 22 is fixedly connected to the inner wall of the fixed component 11; The condensation component 21 drives the rotating component 12 to rotate.

[0024] Auxiliary mechanism 3 includes: Buffer assembly 31 is fixedly connected to the inner wall of fixed assembly 11; The diversion component 32 is fixedly connected to the outer wall of the flow blocking component 22; The buffer component 31 is used to buffer the pressure generated by the fixing component 11, and the diversion component 32 is used to limit the airflow direction.

[0025] Example 2, please refer to Figures 3-9 The present invention is an anti-condensation switch cabinet. Based on Example 1, the fixing component 11 includes a fixing block 111 fixedly connected to the outer wall of the switch cabinet body 13, an exhaust fan 112 fixedly connected to the outer wall of the fixing block 111, and a ventilation filter 113 fixedly connected to the outer wall of the fixing block 111. The fixing block 111 is located on the outside of the switch cabinet 13, and the ventilation fan 112 is located inside the switch cabinet 13.

[0026] The rotating assembly 12 includes a rotating ring 121 rotatably connected to the inner wall of the fixed block 111, a plurality of balls 122 rotatably connected to the outer wall of the rotating ring 121, and two ball grooves 123 formed on the outer wall of the fixed block 111. Among them, the rotating ring 121 is conical, with the large opening close to the ventilation filter 113 and the small opening close to the ventilation fan 112. The two ball grooves 123 are mirrored, and there are sixteen balls 122 arranged in groups of eight. The two groups of balls 122 are mirrored, and the two groups of balls 122 are respectively matched with the ball grooves 123. When the ventilation fan 112 starts, it draws in air from outside the switch cabinet 13. The air first passes through the ventilation filter 113 to block dust and large particles, and then comes into contact with the surface of the condenser fan blades 211. Because the surface temperature of the condenser fan blades 211 is low and the outside air temperature is high, a temperature difference is created. Moisture in the air condenses on the surface of the condenser fan blades 211. The air, with some moisture removed, then passes over the condenser fan blades 211 and enters the ventilation fan 112. The cooler 212 conducts heat to keep the overall temperature of the rotating ring 121 at a low level. Because the condenser fan blades 211 are spiral-shaped, the airflow blows onto the surface of the condenser fan blades 211, causing the condenser fan blades 211 to rotate. When the rotating ring 121 rotates, the ball bearing 122 is matched with the ball bearing groove 123. When the rotating ring 121 rotates, it drives the ball bearing 122 to roll on the ball bearing groove 123, thereby changing the friction between the rotating ring 121 and the fixed block 111 from sliding friction to rolling friction, so that the rotating ring 121 can rotate better. When the rotating ring 121 rotates, the water droplets condensed on the surface of the condenser fan blade 211 are subjected to outward centrifugal force. The water droplets move along the surface of the condenser fan blade 211 in the direction of centrifugal force. Since the rotating ring 121 is set in a conical shape, the water droplets move on the surface of the rotating ring 121 towards the part with a larger diameter of the rotating ring 121, that is, towards the outside of the switch cabinet 13, so that the water droplets can flow to the outside.

[0027] The condensing assembly 21 includes a condensing fan blade 211 fixedly connected to the inner wall of the rotating ring 121, and a cooler 212 fixedly connected to the outer wall of the fixing block 111. The cooler 212 is electrically started, and the cooling surface contacts the outer surface of the rotating ring 121, thereby cooling the rotating ring 121 and thus cooling the condenser fan blades 211.

[0028] The flow-blocking assembly 22 includes a flow-blocking ring 221 fixedly connected to the inner wall of the rotating ring 121, a scraper 222 fixedly connected to the outer wall of the flow-blocking ring 221, and a drainage groove 223 opened on the inner wall of the fixing block 111. Among them, the center of the baffle ring 221 protrudes towards the rotating ring 121, the scraper 222 is made of hard rubber, the scraper 222 contacts the inner surface of the rotating ring 121, and the drain groove 223 leads to the outside of the switch cabinet 13. like Figure 9 As shown, because the center of the splitter plate 322 protrudes towards the rotating ring 121, when the airflow contacts the left surface of the splitter plate 322, the air diffuses outwards. Air enters the gap between the splitter plate 322 and the baffle ring 221, flows along the baffle ring 221, flows along the arc-shaped side of the baffle ring 221 towards the splitter plate 322, and then flows out through the inner diameter of the baffle ring 221. The airflow direction is as follows: Figure 9 The direction of G flow.

[0029] The buffer assembly 31 includes an annular groove 311 formed in the inner wall of the fixed block 111, and a Z-shaped spring piece 312 is fixedly connected to the inner wall of the annular groove 311. One side of the Z-shaped spring 312 is fixed to the fixed block 111, and the other side is in contact with the rotating ring 121.

[0030] The diversion assembly 32 includes a plurality of support columns 321 fixedly connected to the outer wall of the baffle ring 221, and a diversion plate 322 is fixedly connected to the outer wall of the plurality of support columns 321. Among them, several support columns 321 are arranged in a mirror image, the center of the diverter plate 322 protrudes towards the rotating ring 121, and the outer edge of the diverter plate 322 covers the inner diameter of the baffle ring 221. The rotating ring 121 is conical. When the rotating ring 121 rotates, it generates an axial force towards the side with the larger diameter, such as... Figure 9As shown, the Z-shaped spring 312 contacts the rotating ring 121 on the side closest to the rotating ring 121, allowing relative sliding between them. When the rotating ring 121 is subjected to axial force and tends to move to the left, it transitions from a free state to a compressed state. Thus, the Z-shaped spring 312 suppresses the tendency of the rotating ring 121 to move to the left. When the rotating ring 121 rotates at a slower speed, the Z-shaped spring 312 deforms less, and the contact pressure between the left ball 122 and the fixed block 111 is smaller, thus not affecting rotation. When the rotating ring 121 rotates at a higher speed, the Z-shaped spring 312 deforms more, and the contact pressure between the left ball 122 and the fixed block 111 is larger, thus suppressing the rotation speed of the rotating ring 121.

[0031] One specific application of this embodiment is as follows: When in use, the operator installs various electrical components inside the switch cabinet 13, ensures that the device is not working, starts the switch cabinet, and then starts the ventilation fan 112 to ventilate the inside of the switch cabinet 13.

[0032] When the ventilation fan 112 starts, it draws in air from outside the switch cabinet 13. The air first passes through the ventilation filter 113 to block dust and large particles, and then comes into contact with the surface of the condenser fan blades 211. Because the surface temperature of the condenser fan blades 211 is low and the outside air temperature is high, a temperature difference is created, and the moisture in the air condenses on the surface of the condenser fan blades 211. The air with some moisture removed then passes over the condenser fan blades 211 and enters the ventilation fan 112. The cooler 212 conducts heat to keep the overall temperature of the rotating ring 121 at a low temperature. Since the condenser fan blades 211 are spiral-shaped, the airflow blows on the surface of the condenser fan blades 211, causing the condenser fan blades 211 to drive the rotating ring 121 to rotate. The ball bearings 122 are matched with the ball bearing grooves 123. When the rotating ring 121 rotates, it drives the ball bearings 122 to move on the ball bearing grooves 123. Rolling occurs, causing the friction between the rotating ring 121 and the fixed block 111 to change from sliding friction to rolling friction, allowing the rotating ring 121 to rotate more effectively. When the rotating ring 121 rotates, the water droplets condensed on the surface of the condensing fan blade 211 are subjected to outward centrifugal force. The water droplets move along the surface of the condensing fan blade 211 in the direction of centrifugal force. Since the rotating ring 121 is set in a conical shape, the water droplets move on the surface of the rotating ring 121 towards the larger diameter of the rotating ring 121, that is, towards the outside of the switch cabinet 13, allowing the water droplets to flow to the outside. Through the application of the above components, the problem of the ventilation system drawing in high humidity air from the outside into the switch cabinet when the equipment is in a high humidity external working condition is effectively reduced. This causes the humidity of the air inside the cabinet to accumulate and increase continuously, thereby aggravating the condensation phenomenon, causing a significant decrease in insulation resistance, and causing the insulation protection capability of the equipment to continuously deteriorate.

[0033] Utilizing the characteristic of the rotating ring 121 in the aforementioned device, which causes water droplets to move in the direction of centrifugal force, when the water droplets on the condenser fan blade 211 rotate, some water droplets splash to the rear side of the condenser fan blade 211. However, due to the influence of centrifugal force, most of the splashed water droplets are thrown to both sides. Under the obstruction of the baffle ring 221, the water droplets are left on the side of the baffle ring 221 closer to the rotating ring 121. Since the rotating ring 121 is conical, the water droplets tend to move towards the side with the larger diameter of the rotating ring 121 as they rotate with it. These water droplets are affected by the arrangement of the condenser fan blade 211. The water droplets are blocked and difficult to drain from the switch cabinet. By setting up a scraper 222, which is tilted in the direction of rotation of the rotating ring 121, the tendency of water droplets to move towards the larger diameter side of the rotating ring 121 is suppressed. The scraper 222 pushes the accumulated water droplets into the drain channel 223, so that the water droplets can be discharged from the outside of the switch cabinet 13 through the drain channel 223. Through the application of the above components, the tendency of some condensed water droplets to be thrown into the switch cabinet 13 due to the rotation of the rotating ring 121 is effectively reduced, thus reducing the problem of water accumulation in the switch cabinet 13.

[0034] Taking advantage of the characteristic of the rotating ring 121 in the above-mentioned device, the rotating ring 121 is conical. When the rotating ring 121 rotates, it generates an axial force towards the side with the larger diameter, such as... Figure 9 As shown, the Z-shaped spring 312 contacts the rotating ring 121 on the side closest to the rotating ring 121, allowing relative sliding between them. When the rotating ring 121 is subjected to axial force and tends to move to the left, it transitions from a free state to a compressed state. The Z-shaped spring 312 then suppresses this tendency. When the rotating ring 121 rotates at a slower speed, the Z-shaped spring 312 deforms less, resulting in less contact pressure between the left ball bearing 122 and the fixed block 111, thus not affecting rotation. When the rotating ring 121 rotates at a higher speed, the Z-shaped spring 312 deforms more, resulting in greater contact pressure between the left ball bearing 122 and the fixed block 111, thus suppressing the rotational speed of the rotating ring 121. Through the application of these components, the problem of axial force during the rotation of the rotating ring 121, which makes it difficult for the ball bearing 122 to roll and affects the rotation of the rotating ring 121, is effectively prevented.

[0035] The characteristics of air passing through the condenser fan blades 211 as described above, such as Figure 9 As shown, because the center of the splitter plate 322 protrudes towards the rotating ring 121, when the airflow contacts the left surface of the splitter plate 322, the air diffuses outwards. Air enters the gap between the splitter plate 322 and the baffle ring 221, flows along the baffle ring 221, flows along the arc-shaped side of the baffle ring 221 towards the splitter plate 322, and then flows out through the inner diameter of the baffle ring 221. The airflow direction is as follows: Figure 9The flow direction of G, through the application of the above components, effectively prevents some air from flowing directly out of the baffle ring 221 and some air from generating vortices in the arc section of the baffle ring 221, thus preventing a decrease in airflow efficiency.
