Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a condensation-free safety power distribution cabinet. Background Art

[0002] The power distribution cabinet plays a vital role in the modern power system. As the core equipment for power distribution and control, it is responsible for efficiently and safely transmitting power to each power consumption unit to ensure the stable and reliable operation of the entire power grid. Whether in industrial sites, commercial buildings, or urban infrastructure, the power distribution cabinet is the "heart" of the power system. Since its use environment usually includes outdoor and harsh industrial environments, the power distribution cabinet must have a strong ability to resist environmental changes.

[0003] However, in actual applications, power distribution cabinets often face severe tests of humidity and temperature changes. Especially in humid weather with drastic temperature changes, rainy season or continuous rainfall, condensation is very likely to occur on the inner wall of the power distribution cabinet. This condensation is caused by the temperature difference between the inside and outside of the cabinet. When the water vapor in the air condenses on the cabinet wall when it is cold, it forms liquid water droplets. If not removed in time, these condensation droplets may drip onto the internal electrical components, causing electrical short circuits, component corrosion and equipment failure, seriously affecting the safety and operating efficiency of the system, and even causing major electrical accidents.

[0004] At present, the existing condensation removal solutions mainly use dehumidification fans to extract humid air in the cabinet, accelerate air circulation, and reduce humidity. Although this method can reduce the humidity in the air, it cannot directly remove the water droplets that have condensed on the inner wall of the cabinet, especially the condensation condensed on the top and side walls, which is still difficult to remove quickly. In addition, the efficiency of this type of method depends on the speed of air flow and the change of humidity. When the amount of condensation is large and concentrated, the effect is more limited and delayed. If the dew is not handled in time and drips onto electrical components, it will pose a huge threat to the stable operation of the equipment.

[0005] Therefore, the current dehumidification technology has obvious shortcomings, and a more efficient and stable decondensation solution is urgently needed. This solution should be able to directly deal with the condensation on the inner wall to prevent water droplets from harming electrical components, and should have intelligent environmental perception and response capabilities to adapt to the complex and changing external environment. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0007] Therefore, the object of the present invention is to provide a condensation-free safe distribution cabinet, comprising a cabinet body, a condensation-free mechanism located in the cabinet body, and a driving mechanism for driving the condensation-free mechanism to rotate.

[0008] The condensation removal mechanism includes a first scraper and a second scraper, wherein the first scraper is used to scrape off condensation on the inner wall of the top of the cabinet, and the second scraper is used to scrape off condensation on the inner wall of the side of the cabinet.

[0009] A horizontal beam is welded and fixed to the bottom surface of the first scraper strip, a vertical beam is welded and fixed to the side surface of the second scraper strip, a first water-absorbing sponge for absorbing condensation is arranged inside the horizontal beam, a second water-absorbing sponge for absorbing condensation is arranged inside the vertical beam, a water collecting box is welded and fixed to the bottom of the vertical beam, first air suction holes are evenly opened on both side walls of the horizontal beam, and second air suction holes are evenly opened on both side walls of the vertical beam.

[0010] A partition is welded and fixed on the inner wall of the cabinet, the driving mechanism includes a rotating column connected to the partition bearing, a fixing block is sleeved on the rotating column and welded to the rotating column, the top end of the rotating column is connected to the induced draft fan through a first connecting pipe, and the bottom end of the rotating column is connected to one end of the crossbeam through a second connecting pipe.

[0011] The fixing block is slidably connected to the crossbeam.

[0012] As the preferred technical solution:

[0013] In the above-mentioned condensation-free safety distribution cabinet, a group of vertical plates are welded and fixed to the bottom of the cabinet body, and a plurality of horizontal plates are bolted to two of the vertical plates.

[0014] The side wall and the back wall of the cabinet are connected by welding via a connecting plate, and the cross section of the connecting plate is arc-shaped.

[0015] Through the above technical solution, multiple horizontal plates can be installed on the vertical plates, so that components can be installed on the horizontal plates, and the second scraper is arranged around the vertical plates and the horizontal plates, so that the second scraper will not collide with the vertical plates and the horizontal plates when rotating.

[0016] In the above-mentioned condensation-free safety distribution cabinet, the horizontal beam and the vertical beam are welded end to end, the horizontal beam and the vertical beam are combined into an inverted "L" shape, and the horizontal beam and the vertical beam are both hollow.

[0017] An open groove is provided on the top wall of the horizontal beam, a first through hole is provided on the bottom surface of one end of the horizontal beam connected to the vertical beam, both ends of the vertical beam are open, and the top end of the vertical beam is connected to the first through hole.

[0018] Through the above technical solution, since the second connecting pipe is threadedly connected to one end of the horizontal beam, and the horizontal beam and the vertical beam are connected through the first through hole, after the induced draft fan is running, the induced draft fan can generate negative pressure inside the horizontal beam and the vertical beam through the rotating column and the second connecting pipe, and then the air inside the cabinet will be sucked into the horizontal beam and the vertical beam through the first air intake hole and the second air intake hole.

[0019] In the above-mentioned condensation-free safety distribution cabinet, the first scraper strip and the second scraper strip are welded end to end, and the first scraper strip and the second scraper strip are combined into an inverted "L" shape.

[0020] The first scraper strip contacts the inner wall of the top end of the cabinet, and the second scraper strip contacts the inner wall of the side of the cabinet. The contact ends of the first scraper strip and the second scraper strip with the inner wall of the cabinet are both arc-shaped.

[0021] Through the above technical solution, the end faces of the first scraper strip and the second scraper strip are arranged in an arc shape, so that the first scraper strip and the second scraper strip are always in line contact when contacting the inside of the cabinet. This small contact surface can greatly reduce friction and ensure that the first scraper strip and the second scraper strip slide smoothly on the inner wall of the cabinet.

[0022] In the condensation-free safety distribution cabinet as described above, a group of water guide plates are arranged on both sides of the first scraper strip, the two water guide plates are distributed in an inverted "V" shape, the spacing between the top ends of the two water guide plates is consistent with the length of the first scraper strip, and the spacing between the bottom ends of the two water guide plates is less than the length of the opening groove.

[0023] Through the above technical solution, when the first scraper scrapes the condensation on the inner wall of the top of the cabinet, in order to prevent the condensation from sliding down the two ends of the first scraper, a group of water guide plates are provided, so that the water guide plates can limit the flow path of the condensation, ensuring that the condensation can only flow along the two water guide plates to the open groove, and the structure is reasonable.

[0024] In the above-mentioned condensation-free safety distribution cabinet, a plurality of first water guide grooves are provided on two sides of the second scraper strip from top to bottom, and a second water guide groove is provided on two sides of the second scraper strip.

[0025] The first water guide groove is distributed in an inclined shape, the bottom end of the first water guide groove is connected with the second water guide groove, the second water guide groove is distributed in a vertical shape, and the water collecting box is symmetrically arranged with respect to the second scraper strip.

[0026] Through the above technical solution, the water collecting box does not contact the inner wall of the cabinet side, so there is a distance between the water collecting box and the inner wall of the cabinet. When the second scraper scrapes the condensation on the inner wall of the cabinet side, in order to ensure that the condensation can all flow into the water collecting box, a first water guide groove and a second water guide groove are provided. The first water guide groove and the second water guide groove can guide the condensation to flow downward into the water collecting box.

[0027] In the above-mentioned condensation-free safety distribution cabinet, a first through groove is provided inside the first water-absorbing sponge, the outer wall of the first water-absorbing sponge is fixedly bonded to the inner wall of the beam, and a second through hole is provided on the bottom surface of one side of the first water-absorbing sponge.

[0028] The second water-absorbing sponge has a second through groove extending through it, the outer wall of the second water-absorbing sponge is fixedly bonded to the inner wall of the vertical beam, and the top of the second water-absorbing sponge is connected to the second through hole.

[0029] The bottom surface of the second water-absorbing sponge vertically extends downward to form a plurality of water-absorbing strips, and the water-absorbing strips extend into the water collecting box.

[0030] Through the above technical solution, the first through groove and the second through groove are set so that the first water-absorbing sponge and the second water-absorbing sponge are hollow in design, so that air can flow in the first through groove and the second through groove, which can reduce the air flow resistance, thereby ensuring the exhaust rate of the induced draft fan and improving the air circulation rate inside the cabinet.

[0031] In the above-mentioned condensation-free safety distribution cabinet, the rotating column is a circular tubular structure, the rotating column passes through the center of the partition, the inner wall of the top end of the rotating column is connected to the first connecting pipe bearing, the bottom end of the rotating column is sealed and bonded to the second connecting pipe, and the second connecting pipe is a rubber hose;

[0032] An electric motor is bolted to the partition, and an output shaft of the electric motor is transmission-connected to a rotating column gear.

[0033] Through the above technical solution, the output shaft of the motor and the gear on the rotating column form a reduction structure, so that the rotating column can rotate slowly driven by the motor, and then the first scraper and the second scraper can smoothly scrape off the condensation to avoid the condensation being thrown out due to excessive rotation speed.

[0034] In a condensation-free safety distribution cabinet as described above, the driving mechanism also includes a base plate welded and fixed to the bottom surface of the beam, a sliding groove is opened on the side of the base plate, a fixed sliding bar is welded to the side of the fixed block, and the sliding bar is embedded in the sliding groove. The cross-sections of the sliding bar and the sliding groove are both "T"-shaped, and one end of the sliding bar is welded and connected to the groove wall on one side of the sliding groove through an elastic spring.

[0035] Through the above technical solution, while the sliding bar slides along the sliding groove, due to the "T"-shaped design of the sliding bar and the sliding groove, the sliding bar will not slide out of the sliding groove, thereby ensuring that the bottom plate can move stably on the fixed block.

[0036] In the above-mentioned condensation-free safety distribution cabinet, the top surface of the first water-absorbing sponge extends upward to form a convex strip, and the convex strip extends into the open groove.

[0037] The thickness of the first scraper strip is smaller than the width of the opening groove, and the opening groove is symmetrically arranged with respect to the first scraper strip.

[0038] Through the above technical solution, the positions of the first scraper bar and the open groove are designed so that no matter whether the first scraper bar rotates clockwise or counterclockwise, the condensation scraped off by the first scraper bar will flow along the two water guide plates to the open groove.

[0039] Compared with the prior art, the present invention has at least the following beneficial effects:

[0040] (1) Efficient condensation removal and improved equipment safety: The present invention realizes effective removal of condensation on the top and inner wall of the cabinet by providing a first scraper and a second scraper. The scraper rotates synchronously with the rotating column to scrape off the condensation and collect it in the water collection device, thus preventing the condensation from dripping onto the electrical components, thereby preventing the risk of short circuit and corrosion, significantly improving the operating safety of the distribution cabinet, and is particularly suitable for environments with high humidity and large temperature differences.

[0041] (2) Air flow and moisture-absorbing sponge are combined to achieve long-term dehumidification: Water-absorbing sponges are installed inside the horizontal and vertical beams, and form a negative pressure system with the induced draft fan to promote air flow inside the cabinet. When the air flows through the water-absorbing sponge, it takes away moisture, achieving continuous air drying of the sponge, thereby maintaining a long-term dehumidification effect. This design optimizes air flow, improves dehumidification efficiency, and ensures a dry and stable environment inside the cabinet.

[0042] (3) Automatic control and intelligent adaptation to environmental changes: The built-in temperature and humidity sensor monitors the humidity level in the cabinet in real time. When the humidity is too high, the induced draft fan and motor start automatically to ensure timely and effective dehumidification and condensation removal. Through intelligent management, human intervention is reduced, ensuring efficient operation and energy conservation of the device under different environmental conditions, and enhancing the intelligence and automation of the system.

[0043] (4) Optimize the scraper structure and sliding mechanism design to ensure full coverage and removal: The arc design of the first scraper and the second scraper allows them to maintain line contact with the inner wall, reducing friction and ensuring smooth sliding. In addition, the structure equipped with sliding grooves and elastic springs allows the scrapers to move smoothly and always stay close to the inner wall, fully covering and removing condensation and avoiding dead corners. This innovative design improves the dehumidification effect, extends the service life of the equipment, and reduces the maintenance frequency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention discloses a condensation-free safety distribution cabinet, including a cabinet body 1, a condensation-free mechanism located in the cabinet body 1, and a driving mechanism for driving the condensation-free mechanism to rotate.

[0056] The condensation removal mechanism comprises a first scraper strip 2 and a second scraper strip 3 . The first scraper strip 2 is used to scrape condensation on the top inner wall of the cabinet 1 , and the second scraper strip 3 is used to scrape condensation on the side inner wall of the cabinet 1 .

[0057] A horizontal beam 4 is welded and fixed to the bottom surface of the first scraper strip 2, a vertical beam 5 is welded and fixed to the side surface of the second scraper strip 3, a first water-absorbing sponge 8 for absorbing condensation is arranged inside the horizontal beam 4, a second water-absorbing sponge 10 for absorbing condensation is arranged inside the vertical beam 5, a water collecting box 6 is welded and fixed to the bottom of the vertical beam 5, first air suction holes 12 are evenly opened on both side walls of the horizontal beam 4, and second air suction holes 13 are evenly opened on both side walls of the vertical beam 5.

[0058] A partition 21 is welded and fixed on the inner wall of the cabinet 1, and the driving mechanism includes a rotating column 22 connected to the bearing of the partition 21, and a motor 29 is bolted to the partition 21. The output shaft of the motor 29 is gear-connected to the rotating column 22, and a fixing block 23 welded to the rotating column 22 is sleeved on the rotating column 22. The top end of the rotating column 22 is connected to the induced draft fan through a first connecting pipe 28, and the bottom end of the rotating column 22 is connected to one end of the beam 4 through a second connecting pipe 30, and the fixing block 23 is slidably connected to the beam 4.

[0059] When there is a large temperature difference or continuous rainfall and humid weather, water droplets, that is, condensation, will condense on the inner wall of the cabinet 1. In order to prevent condensation from dripping on the top and sides of the cabinet 1, a first scraper 2 and a second scraper 3 are provided. A thermometer and hygrometer are provided in the cabinet 1. The thermometer and hygrometer, the induced draft fan and the motor 29 are all electrically connected. When the thermometer and hygrometer detects that the humidity in the cabinet 1 is too high, the induced draft fan and the motor 29 are powered on. The motor 29 can drive the rotating column 22 to rotate on the axis on the partition 21. By controlling the forward and reverse rotation of the motor 29, the rotating column 22 can intermittently forward and reverse, thereby ensuring that the second scraper 3 only contacts the inner walls of the two sides and the top of the cabinet 1.

[0060] The rotating column 22 drives the horizontal beam 4 to rotate through the fixed block 23, and the horizontal beam 4 drives the vertical beam 5 to rotate synchronously, so that the first scraper 2 and the second scraper 3 on the horizontal beam 4 and the vertical beam 5 can rotate synchronously and scrape off the condensation on the bottom inner wall and the side inner wall of the cabinet 1, and the scraped condensation is absorbed by the first absorbent sponge 8 and the second absorbent sponge 10.

[0061] At the same time, the induced draft fan is powered on and runs, which can generate negative pressure inside the horizontal beam 4 and the vertical beam 5, and then the air in the cabinet 1 is sucked into the horizontal beam 4 and the vertical beam 5 through the first air intake hole 12 and the second air intake hole 13. During the flow of air in the horizontal beam 4 and the vertical beam 5, the air will come into contact with the first water-absorbing sponge 8 and the second water-absorbing sponge 10, so that the moisture on the first water-absorbing sponge 8 and the second water-absorbing sponge 10 can be gradually taken away, thereby achieving air drying of the first water-absorbing sponge 8 and the second water-absorbing sponge 10, and ensuring the continuous water absorption effect of the first water-absorbing sponge 8 and the second water-absorbing sponge 10.

[0062] When there is no condensation and the temperature inside the cabinet 1 is too high, the induced draft fan and the motor 29 are powered on and run. At this time, the vertical beam 5 rotates around the components on the horizontal plate 102. Since the heat flows upward, the horizontal beam 4 and the vertical beam 5 can expand the air intake area by rotating, and can evenly absorb the heat in the cabinet 1, thereby improving the overall heat dissipation effect.

[0063] The prior art such as CN221885742U has disclosed the principle and structure of the thermometer and hygrometer controlling the automatic operation of the fan. Therefore, in this device, how the thermometer and hygrometer controls the induced draft fan and the motor 29 is a well-known technology, and no further elaboration is made here.

[0064] like Figure 2 As shown, a group of vertical plates 101 are welded and fixed to the bottom of the cabinet 1, and a plurality of horizontal plates 102 are bolted to the two vertical plates 101. The side wall and the back wall of the cabinet 1 are welded and connected by a connecting plate 103, and the cross section of the connecting plate 103 is arc-shaped.

[0065] Traditional distribution cabinets are all square, with right angles between the back and the two sides of the cabinet 1. This will result in the first scraper 2 and the second scraper 3 being unable to scrape the right angles of the cabinet 1 when rotating, resulting in dead angles. In order to solve this problem, an arc-shaped connecting plate 103 is installed between the back wall and the side wall of the cabinet 1. The connecting plate 103 replaces the right angle, so that the second scraper 3 can contact the connecting plate 103 when rotating, thereby improving the overall condensation scraping effect.

[0066] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the horizontal beam 4 and the vertical beam 5 are welded end to end and connected. The horizontal beam 4 and the vertical beam 5 are combined into an inverted "L" shape. The horizontal beam 4 and the vertical beam 5 are both hollow. An open groove 7 is provided on the top wall of the horizontal beam 4. A first through hole 14 is provided on the bottom surface of one end where the horizontal beam 4 is connected to the vertical beam 5. Both ends of the vertical beam 5 are open, and the top of the vertical beam 5 is connected to the first through hole 14.

[0067] A first through groove 15 is provided inside the first water-absorbing sponge 8 and runs through the first water-absorbing sponge 8. The outer wall of the first water-absorbing sponge 8 is fixedly bonded to the inner wall of the crossbeam 4. A second through hole 16 is provided on the bottom surface of one side of the first water-absorbing sponge 8. A convex strip 9 is formed on the top surface of the first water-absorbing sponge 8 and extends upward. The convex strip 9 extends into the open groove 7.

[0068] A second through groove 17 is provided inside the second water-absorbing sponge 10, and the outer wall of the second water-absorbing sponge 10 is fixedly bonded to the inner wall of the vertical beam 5. The top of the second water-absorbing sponge 10 is connected to the second through hole 16. The bottom surface of the second water-absorbing sponge 10 extends vertically downward to form a plurality of water-absorbing strips 11, and the water-absorbing strips 11 extend into the water collecting box 6.

[0069] During the process of scraping condensation by the first scraper strip 2 and the second scraper strip 3 , the dew scraped by the first scraper strip 2 will flow into the opening groove 7 , so that the dew will contact with the convex strip 9 , and the convex strip 9 can absorb all the dew.

[0070] The dew scraped off by the second scraper strip 3 will all be concentrated in the water collecting box 6, and the water absorbing strip 11 will absorb the dew at this time. Since the first water absorbing sponge 8 and the second water absorbing sponge 10 have a capillary phenomenon, the dew will infiltrate the first water absorbing sponge 8 through the convex strip 9, and the dew will infiltrate the second water absorbing sponge 10 through the water absorbing strip 11, so that the first water absorbing sponge 8 and the second water absorbing sponge 10 will continuously absorb the dew.

[0071] Through the first through hole 14, the internal spaces of the horizontal beam 4 and the vertical beam 5 are connected. When the induced draft fan is running, negative pressure will be generated inside the hollow horizontal beam 4 and the vertical beam 5, and then the gas in the cabinet 1 will be sucked into the horizontal beam 4 and the vertical beam 5 through the first air intake hole 12 and the second air intake hole 13. During the inhalation process, the air will pass through the first water-absorbing sponge 8 and the second water-absorbing sponge 10, and the first through groove 15 cooperates with the second through hole 16 and the second through groove 17 to form a channel, so that the air will flow along the channel, and will gradually take away the moisture on the surface of the first water-absorbing sponge 8 and the second water-absorbing sponge 10 during the flow process, so that the first water-absorbing sponge 8 and the second water-absorbing sponge 10 can be air-dried.

[0072] like Figure 1 , Figure 3 and Figure 4 As shown, the first scraper strip 2 and the second scraper strip 3 are welded end to end, and the first scraper strip 2 and the second scraper strip 3 are combined into an inverted "L" shape. The first scraper strip 2 contacts the inner wall of the top of the cabinet 1, and the second scraper strip 3 contacts the inner wall of the side of the cabinet 1. The contact ends of the first scraper strip 2 and the second scraper strip 3 with the inner wall of the cabinet 1 are both arc-shaped.

[0073] The thickness of the first scraper strip 2 is smaller than the width of the opening groove 7. The opening groove 7 is symmetrically arranged about the first scraper strip 2. A group of water guide plates 18 are arranged on both sides of the first scraper strip 2. The two water guide plates 18 are distributed in an inverted "V" shape. The distance between the top ends of the two water guide plates 18 is consistent with the length of the first scraper strip 2, and the distance between the bottom ends of the two water guide plates 18 is smaller than the length of the opening groove 7.

[0074] A plurality of first water guide grooves 19 are provided on both sides of the second scraper strip 3 from top to bottom, and a second water guide groove 20 is provided on both sides of the second scraper strip 3. The first water guide grooves 19 are distributed in an inclined shape, and the bottom ends of the first water guide grooves 19 are connected to the second water guide grooves 20. The second water guide grooves 20 are distributed vertically, and the water collecting box 6 is symmetrically arranged about the second scraper strip 3.

[0075] When the first scraper 2 and the second scraper 3 rotate, the first scraper 2 will scrape off the condensation on the inner wall of the top of the cabinet 1, and the second scraper 3 will scrape off the condensation on the inner wall of the side of the cabinet 1. When the first scraper 2 is scraping, the scraped dew will adhere to the two sides of the first scraper 2 and flow along the sides of the first scraper 2. The setting of the water guide plate 18 will limit the flow path of the dew, forcing the dew to flow only toward the opening groove 7.

[0076] When the second scraper 3 is scraping, the scraped dew will adhere to the two sides of the second scraper 3 and flow downward along the side of the second scraper 3. The setting of the first water guide groove 19 makes the dew flow into the first water guide groove 19 during the downward flow and flow downward obliquely along the first water guide groove 19. In this way, under the guidance of the first water guide groove 19, the dew is collected in the second water guide groove 20 and flows downward in a concentrated manner. Finally, all the dew can be collected by the water collecting box 6.

[0077] like Figure 1 and Figure 4 As shown, the rotating column 22 is a circular tubular structure. The rotating column 22 passes through the center of the partition 21. The inner wall of the top end of the rotating column 22 is bearing-connected to the first connecting pipe 28. The bottom end of the rotating column 22 is sealed and bonded to the second connecting pipe 30. The second connecting pipe 30 is a rubber hose.

[0078] The top end of the first connecting pipe 28 passes through the cabinet 1 and is connected to an induced draft fan. The first connecting pipe 28 cooperates with the rotating column 22 and the second connecting pipe 30 to form a pipeline. When the induced draft fan is running, the air inside the horizontal beam 4 and the vertical beam 5 can be continuously extracted through the pipeline, so that negative pressure can be formed inside the horizontal beam 4 and the vertical beam 5, so as to continuously extract the gas inside the cabinet 1. In order to ensure that the air inside the cabinet 1 can flow normally, ventilation holes are provided on the two side walls of the bottom of the cabinet 1. Dehumidification and heat dissipation can be achieved by increasing the air circulation rate inside the cabinet 1.

[0079] Since the cross beam 4 can move back and forth linearly on the fixing block 23 , the second connecting pipe 30 can be configured as a hose, thereby preventing the second connecting pipe 30 from being damaged.

[0080] like Figure 4 and Figure 7 As shown, the driving mechanism also includes a bottom plate 24 welded and fixed to the bottom surface of the cross beam 4, a sliding groove 26 is opened on the side of the bottom plate 24, a sliding bar 25 is welded and fixed on the side of the fixed block 23, and the sliding bar 25 is embedded in the sliding groove 26. The cross-sections of the sliding bar 25 and the sliding groove 26 are both "T"-shaped, and one end of the sliding bar 25 is welded to the groove wall on one side of the sliding groove 26 through an elastic spring 27.

[0081] The sliding bar 25 can slide linearly in the sliding groove 26 , so that the bottom plate 24 forms a sliding structure on the fixed block 23 , and under the action of the elastic spring 27 , the bottom plate 24 further forms an elastic sliding structure.

[0082] When the second scraper 3 contacts the side wall of the cabinet 1, the sliding bar 25 will apply an extrusion force to the elastic spring 27, thereby ensuring that the second scraper 3 is tightly pressed against the inner wall of the side of the cabinet 1, and when the second scraper 3 contacts the connecting plate 103, the elastic spring 27 will gradually restore its deformation and push the sliding bar 25 to move in the sliding groove 26, the sliding bar 25 drives the cross beam 4 to move through the bottom plate 24, and the cross beam 4 drives the second scraper 3 to press against the connecting plate 103 through the vertical beam 5.

[0083] When the second scraper strip 3 is pressed against the back wall of the cabinet 1, the horizontal distance between the back wall of the cabinet 1 and the rotating column 22 is smaller than the horizontal distance between the side inner wall of the cabinet 1 and the rotating column 22. In this way, the second scraper strip 3 will move again under the pressure of the back wall of the cabinet 1. During the movement, the elastic spring 27 will be squeezed. Under the elastic force of the elastic spring 27, it can be ensured that the second scraper strip 3 is pressed against the back wall of the cabinet 1.

[0084] Through the above-mentioned structural design, the second scraper 3 can be pressed against the side surface, the back inner wall and the connecting plate 103 of the cabinet 1 during the rotation process, so as to ensure the scraping effect of the condensation, and the first scraper 2 can also move in a straight line during the process, which can expand its scraping range and ensure that all the condensation inside the top of the cabinet 1 can be scraped off.
