Description

Technical Field

[0001] This application relates to the field of electric linear actuator technology, and in particular to a photovoltaic solar-powered electric linear actuator. Background Technology

[0002] As a key drive component of the photovoltaic solar power system, the electric actuator is responsible for precisely adjusting the angle at which the photovoltaic panels receive sunlight. Its operational stability directly determines the overall power generation efficiency of the photovoltaic power station. Since photovoltaic power stations are mostly deployed outdoors, the protective outer cylinder of the electric actuator is in direct contact with the external environment. Drastic temperature differences between day and night and between seasons create significant temperature and humidity differences between the inside of the cylinder and the outside. Moisture in the air easily condenses on the cylinder wall and the surface of the internal structure. If this condensation is not removed in time, it will gradually accumulate at the bottom of the cylinder and in the gaps between the transmission components. Over time, this will adversely affect the internal structure of the actuator, thus threatening its normal operation and service life.

[0003] Existing photovoltaic solar cell electric actuators typically use a motor to drive a lead screw to rotate, which in turn drives a telescopic cylinder to extend and retract linearly. Condensation caused by large temperature differences between day and night is usually addressed through simple sealing or natural air drying. However, this method is extremely ineffective at removing condensation. The condensate inside the cylinder cannot be scraped off in time and continues to accumulate, directly wetting core transmission components such as the lead screw, causing corrosion and oxidation, leading to actuator jamming during extension and retraction, and reduced angle adjustment accuracy. Furthermore, the condensate mixes with debris to form sludge that adheres to the structural surface. Summary of the Invention

[0013] Preferably, the edge corresponding to the apex corner of one cross-section of the limiting block is provided as a smooth curved surface.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: (1) This invention proposes a photovoltaic solar electric actuator, which consists of a mounting plate, a mounting base, a threaded rod, several mounting rings, an inner cylinder, two mounting rings, two sleeves, a plug rod, two buffer springs, several mounting blocks, several rotating rollers, several lifting blocks, and several scraper plates. A rotating motor drives the mounting base and the threaded rod to rotate synchronously at different speeds via a drive assembly. The rotation of the threaded rod drives the mounting rings and the inner cylinder to rotate synchronously, and the rotation of the inner cylinder drives the lifting blocks to rotate synchronously. The lifting blocks and the rotating rollers rotate synchronously. When the rollers make contact, the thrust of the trapezoidal structure drives the insert rod to move vertically upward within the sleeve. The lifting block rotates past the subsequent buffer spring, releasing its elastic potential energy and causing the insert rod to return to its original position. Simultaneously, the rotation of the inner cylinder drives the insert rod and the scraper to revolve. Combined with the synchronous action of the actuating mechanism, the scraper ultimately adheres to the inner circumference of the outer protective cylinder, performing a combined scraping and vertical lifting and resetting motion. This achieves the coordinated action of the scraper's revolving scraping and smooth upward resetting, effectively removing stubborn deposits from the outer protective cylinder wall in layers and preventing residue accumulation.

[0015] (2) The present invention proposes a photovoltaic solar electric push rod, which is equipped with several mounting rings three, several limiting rings, several limiting blocks one, several actuating plates, several rotating rollers two, and several sets of buffer components. When the inner cylinder rotates with the threaded rod and the mounting seat rotates slowly in sync, the mounting rings three revolve with the insertion rod one, the limiting rings and limiting blocks one rotate synchronously, and the rotating rollers two slide along the triangular inclined surface when the limiting blocks one rotates to the corresponding position. Under the action of thrust, the actuating plate moves away from the telescopic rod. After its smooth curved surface extends out, it contacts the scraper plate and drives the scraper plate to rotate around the torsion spring shaft. After the actuating plate passes over the scraper plate, the scraper plate quickly resets by the torsion spring shaft to generate ripples, shaking off the residue and condensate at the blade edge, avoiding accumulation and jamming. After the inner cylinder continues to rotate, the rotating rollers two disengage from the inclined surface of the limiting blocks one, and the buffer components drive the actuating plate to reset, realizing the shaking off of the residue attached to the scraper blade edge, avoiding the scraping jamming caused by the accumulation and jamming of residue and condensate.

[0027] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0029] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0030] One preferred embodiment of this application, such as Figures 1 to 10 As shown, a photovoltaic solar-powered electric actuator includes: a protective outer cylinder 1, and further includes: a telescopic rod 10, a rotary motor 11, a scraping assembly, a telescopic assembly, a limiting assembly, a toggle mechanism, a collecting assembly, and a drive assembly; the telescopic rod 10 is inserted into the protective outer cylinder 1; the rotary motor 11 is fixedly installed on the bottom inner wall of the protective outer cylinder 1; there are two sets of scraping assemblies, which are respectively arranged on both sides of the telescopic rod 10 to scrape water droplets and impurities on the inner circumference of the protective outer cylinder 1; the telescopic assembly is arranged between the telescopic rod 10 and the protective outer cylinder 1 to... The telescopic rod 10 is extended or shortened; a limiting component is installed at the bottom circumference of the telescopic rod 10 to limit the extension or shortening of the telescopic rod 10 in conjunction with the telescopic component; there are two sets of actuating mechanisms, which are respectively set on both sides of the telescopic rod 10 to actuate the scraping component to discharge the hanging impurities; a collecting component is set inside the protective outer cylinder 1 to collect the scraped impurities; and a driving component is installed on the bottom inner wall of the protective outer cylinder 1 to synchronously drive the scraping component to perform scraping operation when the telescopic component is extended or shortened.

[0031] After starting the rotating motor 11, the output shaft of the rotating motor 11 drives the drive assembly to operate. The drive assembly drives the telescopic assembly to move, which in turn drives the telescopic rod 10 to retract inward or extend outward along the protective outer cylinder 1. During this process, the limiting assembly works synchronously to precisely limit the telescopic rod 10 during telescopic movement, ensuring that its telescopic movement is smooth and does not deviate. On the other hand, the drive assembly synchronously drives the two sets of scraping assemblies to move, so that the scraping assemblies are in contact with the inner circumference of the protective outer cylinder 1 to scrape and thoroughly remove condensate droplets and impurities on the cylinder wall. During the scraping process, the two sets of actuating mechanisms work synchronously to continuously actuate the scraping assemblies, promptly removing the residue and condensate adhering to the scraping assemblies to prevent them from being blocked or stuck, ensuring smooth scraping. Finally, the removed residue and condensate fall off under the action of gravity and collect in the collection assembly for centralized collection, realizing the synchronous operation of the telescopic rod 10 telescopic adjustment and the scraping, removal, and collection of condensate and impurities in the protective outer cylinder 1.

[0032] Further reference Figures 2-4 and Figures 6-9The telescopic assembly includes: a mounting plate 201, a mounting base 202, and a threaded rod 203. The mounting plate 201 is horizontally fixed to the bottom of the inner circumference of the protective outer cylinder 1. The mounting base 202 is rotatably mounted to the top of the mounting plate 201. The threaded rod 203 is vertically rotatably mounted to the top of the mounting base 202. The bottom of the telescopic rod 10 has a mounting groove, and the inner circumference of the mounting groove has threads adapted to the threaded rod 203. The scraping assembly includes: several mounting rings 204, an inner cylinder, and a mounting plate 201. 205, mounting ring 206, two sleeves 207, insert rod 208, two buffer springs 209, several mounting blocks 2010, several rotating rollers 2011, several lifting blocks 2012, and several scraper plates 2013. One mounting ring 204 is horizontally fitted onto the bottom of the circumference of the threaded rod 203. The inner cylinder 205 is vertically fixed to the top of one of the mounting rings 204. Mounting ring 206 is fitted onto the outer wall of the circumference of the inner cylinder 205 via a bearing. At the top, one sleeve 207 is vertically fixed to one side of the bottom of the mounting ring 206, and the other sleeve 207 is vertically positioned directly above the top of the mounting base 202. A vertically positioned insertion rod 208 is inserted into the two sleeves 207 at its top and bottom, respectively. Two buffer springs 209 are fixedly installed between the top and bottom of the insertion rod 208 and the two sleeves 207, respectively. Several mounting blocks 2010 are arranged and fixedly installed on the insertion rod. On one side of 208, several rotating rollers 2011 are rotatably mounted on one side of several mounting blocks 2010 near the telescopic rod 10. Other mounting rings 204 are arranged and fitted around the outer circumference of the inner cylinder 205. Several lifting blocks 2012 are fixedly mounted on one side of several mounting rings 204. The cross-section of the lifting blocks 2012 is a trapezoid with inclined sides. Several scraper plates 2013 are rotatably mounted on one side of the insert rod 208 through torsion spring shafts.

[0033] After the rotary motor 11 is started, the output shaft of the rotary motor 11 drives the mounting base 202 and the threaded rod 203 to rotate synchronously through the drive assembly. The rotation speed of the threaded rod 203 is faster than that of the mounting base 202. One of the mounting rings 204, which is sleeved on the bottom of the circumference of the threaded rod 203, rotates with the threaded rod 203, thereby driving the inner cylinder 205, which is fixed to the top of the mounting ring 204, to rotate synchronously. Because the rotation speed of the mounting base 202 is slower, the rotation speed of the inner cylinder 205 is also slightly lower than that of the threaded rod 203. During the rotation of the inner cylinder 205, the inner cylinder 205 is lifted on the outer circumference of the mounting ring 204. Block 2012 rotates together with the inner cylinder 205. When the lifting block 2012 contacts the rotating roller 2011 at the mounting point of block 2010 on the insert rod 208, because the lifting block 2012 has a trapezoidal cross-section with inclined sides, it will generate an upward thrust on the insert rod 208 through the rotating roller 2011, causing the insert rod 208 to move vertically upward within the two sleeves 207. At the same time, it compresses the buffer springs 209 at the top and bottom of the insert rod 208. After the lifting block 2012 rotates past the rotating roller 2011, the buffer springs 209 release their elastic potential energy, driving the insert rod... As the inner cylinder 205 rotates, it simultaneously drives the insert rod 208 and the scraper 2013 mounted on one side of the insert rod 208 to revolve. This causes the scraper 2013 to scrape against the inner circumference of the outer protective cylinder 1, thoroughly removing condensate droplets and impurities from the cylinder wall. Simultaneously, the actuating mechanism works in sync, continuously actuating the scraper 2013 to promptly remove residue and condensate adhering to it, preventing accumulation and jamming. The trapezoidal lifting block 2012, in conjunction with the rotating roller 2011, achieves a smooth lifting motion. The lifting motion avoids continuous hard contact between the scraper 2013 and the inner wall of the protective outer cylinder 1, reducing wear on the scraper 2013 and extending its service life. The reciprocating lifting motion can create a layered scraping effect on stubborn deposits on the cylinder wall. When the scraper 2013 moves upward, it peels off the surface deposits, and after resetting, it scrapes off the bottom residue by adhering to the cylinder wall. This is more thorough than simple revolution scraping. At the same time, it avoids the accumulation and agglomeration of residue on the cutting edge of the scraper 2013. By moving upward and resetting, the residue that was originally accumulated at the cutting edge is separated from the cutting edge after moving up and down.

[0034] Further reference Figure 7 and Figure 10The actuating mechanism includes: several mounting rings 301, several limiting rings 302, several limiting blocks 303, several actuating plates 304, several rotating rollers 305, and several sets of buffer components. The mounting rings 301 are horizontally arranged and fixedly installed between the two insert rods 208 on their adjacent sides. The limiting rings 302 are fixedly installed on the top of the mounting rings 301. The limiting blocks 303 are arranged and fixedly installed on one side of the limiting rings 302. The cross-section of the limiting blocks 303 is triangular. Several actuating plates 304 are arranged on the top of several mounting rings 301. One end of the actuating plate 304 is provided with an installation port near the telescopic rod 10, and the other side of the actuating plate 304 is provided with a smooth curved surface. Several rotating rollers 305 are horizontally rotated and installed on the inner wall of the top of several installation ports. Several rotating rollers 305 are in contact with several limiting blocks 303. Several sets of buffer components are installed between several actuating plates 304 and the outer circumference of the inner cylinder 205. The edge corresponding to the apex corner of the limiting block 303 is provided with a smooth curved surface.

[0035] When the inner cylinder 205 rotates with the threaded rod 203 and the mounting base 202 rotates slowly in sync, several mounting rings 301 fixed between the two insert rods 208 revolve together with the insert rods 208. The limiting ring 302 at the top of the mounting ring 301 and the triangular limiting block 303 fixed thereon also rotate synchronously. Normally, the actuating plate 304 is in contact with the limiting block 303 via the rotating roller 205. When the limiting block 303 rotates to the corresponding position, the rotating roller 205 slides along the triangular inclined surface of the limiting block 303. Under the thrust of the inclined surface, the actuating plate 304 moves towards the telescopic rod 10. At this time, the smooth curved surface on the other side of the actuating plate 304 extends outward, compressing the buffer assembly between it and the inner cylinder 205. The extended actuating plate 304 and the insert rod 208 rotate together. When the scraper plate 2013 on the upper part of the cylinder 8 contacts the scraper plate 2013, it causes the scraper plate 2013 to rotate around the torsion spring shaft. After the actuating plate 304 completely passes over the scraper plate 2013, the scraper plate 2013 quickly resets under the action of the torsion spring shaft, producing a slight ripple. This shakes off the residue and condensate adhering to the cutting edge of the scraper plate 2013, causing it to fall quickly to the lower sliding structure. This prevents the scraper plate 2013 from accumulating and clumping on the cutting edge, which would cause the scraper plate to jam. As the inner cylinder 205 continues to rotate, the rotating roller 205 disengages from the inclined surface of the limiting block 1 303. The buffer component releases its elastic potential energy, causing the actuating plate 304 to return to the return position and no longer contact the scraper plate 2013. A slot can be opened at the corresponding position of the insert rod 1 208 to fit the shape of the actuating plate 304 after reset, ensuring that the actuating plate 304 is completely retracted and does not affect the revolution and scraping action of the insert rod 1 208 and the scraper plate 2013.

[0036] Further reference Figure 5The drive assembly includes: two rotating shafts 401, a mounting tube 402, a first gear 403, a second gear 404, and two third gears 405. The top of one rotating shaft 401 is fixedly mounted to the bottom of the threaded rod 203. The bottom of one rotating shaft 401 passes through the mounting base 202 and the first mounting plate 201 in sequence. The other rotating shaft 401 is vertically fixedly mounted to the output shaft of the rotating motor 11. The top of the first mounting plate 201 has an annular opening. The top of the mounting tube 402 is fixedly mounted to the bottom of the mounting base 202. The bottom of the mounting tube 402 passes through the opening. The first gear 403 is fitted onto the bottom of the outer circumference of the mounting tube 402. The second gear 404 is fitted onto the bottom of one of the rotating shafts 401. The radius of the second gear 404 is smaller than that of the first gear 403. The two third gears 405 are respectively fitted onto the other rotating shaft 401. The two third gears 405 are meshed with the first gear 403 and the second gear 404, respectively.

[0037] After the rotary motor 11 is started, the output shaft of the rotary motor 11 drives another rotary shaft 401, which is vertically fixed thereto, to rotate synchronously. Two gears 405, sleeved on this rotary shaft 401, rotate together with the shaft. Since the two gears 405 mesh with gear 1 403 and gear 2 404 respectively, power is transmitted to gear 1 403 and gear 2 404 through gear meshing. Gear 2 404 is sleeved at the bottom of one of the rotary shafts 401 that passes through the mounting base 202 and the mounting plate 201. The rotary shaft 401 that rotates with gear 2 404 will drive the threaded rod 203 fixedly mounted on its top to rotate synchronously. Gear 1 403 is sleeved on... The bottom of the outer circumference of the mounting tube 402 is fixedly connected to the bottom of the mounting base 202, and the bottom of the mounting tube 402 passes through the annular opening at the top of the mounting plate 201. Therefore, when the gear 1 403 rotates, it will drive the mounting tube 402 and the mounting base 202 to rotate together. Since the radius of the gear 2 404 is smaller than that of the gear 1 403, under the transmission action of the same rotating shaft 401 and the gear 3 405, the rotation speed of the gear 2 404 is faster than that of the gear 1 403. This achieves the transmission effect that the rotation speed of the threaded rod 203 is greater than that of the mounting base 202, providing power for the subsequent extension and retraction of the telescopic rod 10 and the differential rotation of the inner cylinder 205 and the mounting base 202.

[0038] Further reference Figure 8 The limiting assembly includes: two limiting groove plates 501, two limiting blocks 502, and four rotating rollers 503. The two limiting groove plates 501 are vertically fixed on both sides of the inner wall of the inner cylinder 205. The two limiting blocks 502 are fixed on the bottom of both sides of the telescopic rod 10. The two rotating rollers 503 form a group. Both ends of the limiting blocks 502 are provided with mounting grooves. The two rotating rollers 503 in the two groups are rotatably installed in the four mounting grooves. The two rotating rollers 503 in the two groups are in contact with the inner walls of both sides of the two limiting groove plates 501.

[0039] When the threaded rod 203 rotates to drive the telescopic rod 10 to perform vertical linear telescopic movement along the protective outer cylinder 1, the limiting component is activated simultaneously and completes the limiting and guiding operation. The two limiting blocks 502 move vertically synchronously with the telescopic rod 10. The two sets of rotating rollers 503 installed in the grooves at both ends of the limiting blocks 502 are always in close contact with the inner walls on both sides of the corresponding limiting groove plate 501. During the telescopic movement of the telescopic rod 10, the two sets of rotating rollers 503 roll synchronously along the vertical inner wall of the limiting groove plate 501. Through the close cooperation between the rotating rollers 503 and the limiting groove plate 501, the circumferential rotation of the telescopic rod 10 is restricted, ensuring that the telescopic rod 10 always performs linear telescopic movement in the vertical direction. At the same time, the sliding friction between the telescopic rod 10 and the limiting groove plate 501 is converted into rolling friction, which greatly reduces the frictional resistance during the telescopic process and makes the telescopic movement of the telescopic rod 10 more stable and smooth.

[0040] Further reference Figure 6 A sliding platform 601 is fixedly installed at the top edge of the mounting base 202. A second sliding platform 602 is provided between the top of the mounting base 202 and the threaded rod 203. Both the first sliding platform 601 and the second sliding platform 602 are tapered. The collection assembly includes a collection plate 701 and a collection bin 702. The collection plate 701 is vertically fixedly installed on one side of the mounting base 202. The bottom of the collection plate 701 is in contact with the top of the first sliding platform 601. A collection opening is provided on one side of the outer circumference of the protective outer cylinder 1. The collection bin 702 is fixedly installed between the inner walls of the two ends of the collection opening.

[0041] After the condensate and residue scraped by the scraping assembly and shaken off by the actuating mechanism fall into the protective outer cylinder 1, they first fall onto the conical sliding platform 602. Guided by the conical structure of the sliding platform 602, the condensate and residue flow outwards and finally fall onto the sliding platform 601 at the top edge of the mounting base 202. The sliding platform 601 is also conical, which further guides the condensate and residue towards the top edge of the mounting base 202, causing the condensate and residue to collect at the edge of the sliding platform 601. During the rotation of the mounting base 202, the top sliding platform 601 will rotate synchronously. As the condensate and residue on the edge of the material platform 601 rotates to the position of the collection plate 701, they come into contact with the vertically fixed collection plate 701. The collection plate 701, made of elastic material, scrapes the condensate and residue on the material platform 601 together, preventing the material from being scattered and piled up. As the mounting base 202 continues to rotate, the elastic collection plate 701 pushes the scraped condensate and residue toward the collection opening on the outer circumference of the protective outer cylinder 1, allowing the condensate and residue to slide smoothly into the collection opening and finally fall into the collection bin 702 at the collection opening, completing the centralized collection of condensate and residue.

[0042] Further reference Figure 10 The buffer assembly includes: sleeve 2 801, insert rod 2 802 and buffer spring 2 803. Several sleeves 2 801 are arranged and fixedly installed on one side of the outer circumference of the inner cylinder 205. One end of the insert rod 2 802 is inserted into the sleeve 2 801, and the other end of the insert rod 2 802 is fixedly installed with one end of the actuating plate 304. The buffer spring 2 803 is fixedly installed between one end of the insert rod 2 802 and the sleeve 2 801.

[0043] When the actuating plate 304 moves away from the telescopic rod 10 under the thrust of the inclined surface of the limiting block 303, it will drive the fixedly connected insert rod 802 to move synchronously, causing the insert rod 802 to extend outward along the inner wall of the sleeve 801. At the same time, it stretches the buffer spring 803 between one end of the insert rod 801 and the sleeve 801, providing a smooth extension buffer for the actuating plate 304 and avoiding damage caused by hard contact between the actuating plate 304 and the scraper 2013. When the rotating roller 305 disengages from the limiting block 303 and the thrust disappears, the buffer spring 803 releases its elastic potential energy, pulling the insert rod 802 back into the sleeve 801 to reset, thereby driving the actuating plate 304 to move synchronously to the return position, disengaging from contact with the scraper 2013, ensuring that the actuating plate 304 stably returns to the initial position and does not interfere with the revolution and scraping action of the scraper assembly.

[0044] Working principle: After starting the rotating motor 11, its output shaft drives the corresponding rotating shaft 401 to rotate synchronously with the two gears 405. Power is transmitted through the meshing of gears 405 with gears 403 and 404. By utilizing the radius difference between gears 404 and 403, the rotation speed of the threaded rod 203 is faster than that of the mounting base 202, providing a power basis for subsequent actions. The rotation of the threaded rod 203 drives the telescopic rod 10 to perform vertical linear telescopic movement along the protective outer cylinder 1. The limiting component synchronously limits and guides the movement. The limiting block 502 moves vertically synchronously with the telescopic rod 10. The rotating rollers 503 at both ends of the limiting block 503 roll along the vertical inner wall of the limiting groove plate 501, restricting the circumferential rotation of the telescopic rod 10, converting sliding friction into rolling friction to reduce resistance, and ensuring that the telescopic rod 10 extends and retracts smoothly. Simultaneously, the mounting ring 204 fitted at the bottom of the threaded rod 203 drives the inner cylinder 205 to rotate synchronously. The lifting block 2012 on the outer wall of the inner cylinder 205 rotates with it and contacts the rotating roller 2011 on the insert rod 208, pushing the insert rod 208 to move vertically upward in the sleeve 207 and compressing the buffer spring 209. When the lifting block 2012 passes the rotating roller 2011, the buffer spring 209 releases its elastic potential energy, causing the insert rod 208 to return to its original position downward. While the inner cylinder 205 rotates, it drives the insert rod 208 and the scraper 2013 to revolve. The scraper 2013 adheres to the inner circumference of the outer protective cylinder 1, and together with the up-and-down reciprocating lifting action, it forms a layered scraping effect, thoroughly removing condensate droplets and impurities on the cylinder wall, while avoiding continuous hard contact between the scraper 2013 and the cylinder wall to prevent wear and tear, and preventing residue from accumulating and agglomerating on the cutting edge of the scraper 2013. When the inner cylinder 205 rotates, the mounting ring 301 fixed between the two insert rods 208 revolves together with the insert rods 208. The limiting block 303 at the top of the mounting ring 301 rotates synchronously, causing the rotating roller 305 to slide along the triangular inclined surface of the limiting block 303, pushing the actuating plate 304 to move towards the telescopic rod 10, while compressing the buffer assembly between it and the inner cylinder 205. The extended actuating plate 304 contacts the scraper 2013 and drives it to rotate around the torsion spring shaft. After the actuating plate 304 completely passes over the scraper 2013, the scraper 2013 quickly resets under the action of the torsion spring shaft, generating slight fluctuations to shake off the residue and condensate at the cutting edge. When the rotating roller 305 disengages from the inclined surface of the limiting block 303, the buffer assembly releases elastic potential energy to drive the actuating plate 304 to the return position, disengaging from the scraper 2013, without interfering with the revolving scraping action of the scraping assembly.The condensate and residue shaken off fall onto the conical sliding platform 602 under gravity. Guided by the structure of the sliding platform 602, they flow outward and eventually fall onto the conical sliding platform 601. They then flow towards the top edge of the mounting base 202. As the mounting base 202 rotates, it drives the top sliding platform 601 to rotate synchronously. When the condensate and residue at the edge of the sliding platform 601 rotates to the position of the collecting plate 701, the elastic collecting plate 701 scrapes them together. As the mounting base 202 continues to rotate, the collecting plate 701 pushes the scraped condensate and residue towards the collection opening on the outer circumference of the protective outer cylinder 1, allowing the material to slide smoothly into the collection chamber 702 inside the collection opening. This completes the centralized collection of condensate and residue, achieving simultaneous scraping and drainage of condensate inside the protective outer cylinder 1 while adjusting the telescopic movement. The push rod operates stably and has a long service life.
