Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an industrial air conditioning cooling machine. Background Art

[0002] Industrial air conditioning refers to large-scale air conditioning systems designed, manufactured and installed specifically for industrial production and commercial application environments. Compared with household air conditioning, industrial air conditioning has stronger cooling capacity, can adapt to harsh working environments, and is more durable.

[0003] Related technologies ensure that air conditioners deliver clean, odor-free cooling air by constantly cleaning the air outlet filters. However, during use, industrial air conditioners can become contaminated with dust on their fan blades. Due to the low temperatures of winter, industrial air conditioners are often shut down to conserve energy. During these extended periods of shutdown, bacteria can grow on the fan blades, causing odor in the air when the air conditioner is turned on. This can negatively impact the work environment and harm workers' health.

[0004] A Chinese patent with authorization announcement number CN111271858B discloses a fan blade self-cleaning device and an air conditioner. The fan blade self-cleaning device includes a guide device, a cleaning device and a driving device. The guide device is arranged on the air duct of the air conditioner. The guide device includes a first guide shaft arranged on the air duct in a vertical direction and a second guide shaft arranged parallel to the first guide shaft. The end of the cleaning device is arranged on the first guide shaft through a first fixing unit, and the middle of the cleaning device is arranged on the second guide shaft through a second fixing unit. The driving device includes a first driving mechanism for driving the first guide shaft to move up and down. The first driving mechanism includes a first driving motor installed on the top of the guide device, a first screw rod arranged parallel to the first guide rod, and a first nut sleeved on the first screw rod and engaged with the first screw rod. The first nut is fixed on the first guide shaft.

[0005] The aforementioned fan blade self-cleaning device rotates a first screw driven by a first drive motor, causing the first nut to reciprocate up and down along the axial direction of the first guide shaft. This causes the cleaning device to deploy after rotation and swing about its connection with the second guide shaft, thereby cleaning the blades. However, after prolonged use, a large amount of dust and bacteria may adhere to the cleaning device, reducing the cleaning device's effectiveness in cleaning the fan blades, and causing dust or bacteria to always adhere to the blades. Summary of the Invention

[0006] The present invention provides an industrial air-conditioning cooling machine, aiming to solve the problem in the related art that a cleaning device itself is difficult to clean, resulting in reduced cleaning effect.

[0007] The industrial air-conditioning cooling machine of the present invention comprises: a frame, a fan, a compressor and a condenser pipe; The fan, the compressor and the condenser are all arranged on the frame, the compressor is used to extract external air and discharge it to the fan, the condenser is used to cool the air discharged to the fan, and the fan is used to discharge the cooled air; The fan includes a fan housing, a drive motor, fan blades and a cleaning device, the drive motor is arranged in the fan housing, the fan blades are rotated in the fan housing, the drive motor is used to drive the fan blades to rotate, the cleaning device includes a drive mechanism, a movable ring, a rotating seat, a first scraper, a second scraper and a nozzle, the movable ring is arranged in the fan housing, the drive mechanism is used to drive the movable ring to move along the axial direction of the fan housing, the rotating seat is rotatably fitted on the fan housing, the first scraper and the second scraper are spaced apart on the rotating seat, the first scraper and the second scraper can be respectively tightly attached to the two side walls of the fan blades, the first scraper and the second scraper are both provided with water storage boxes, the nozzle is arranged on the first scraper and the second scraper, and can be communicated with the water storage box.

[0008] Beneficial effects: When the fan is working normally, the first scraper and the second scraper are spaced apart and parallel to the fan blades. When the fan stops, the fan blades stop at a fixed position. At this time, the fan blades are located next to the cleaning device. The rotating seat is driven to rotate 90 degrees by the rotating mechanism, so that the first scraper and the second scraper are perpendicular to the fan blades, and the first scraper and the second scraper are in close contact with the fan blades. When the driving mechanism drives the moving ring to move inward along the axial direction of the fan casing, the first scraper and the second scraper can scrape off the dust and impurities on the fan blades. When the first scraper and the second scraper complete cleaning the fan blades, the nozzle is connected to the water storage box and sprays water to the first scraper and the second scraper to wash away the dust and impurities attached to the first scraper and the second scraper, thereby cleaning the first scraper and the second scraper.

[0009] Preferably, a rotating mechanism is provided on the movable ring, and the rotating mechanism includes a driving ring, a first driving member, a rotating shaft, a cam and a connecting rod. The driving ring is slidably fitted in the movable ring. The first driving member is provided on the movable ring, and is used to drive the driving ring to move along the axial direction of the movable ring. The rotating shaft is fixedly connected to the rotating seat, the large diameter end of the cam is connected to the end of the rotating shaft, one end of the connecting rod is hinged to the small diameter end of the cam, and the other end of the connecting rod passes through the movable ring and is hinged to the driving ring.

[0010] Preferably, the first scraper is fixedly connected to the rotating seat, the second scraper is spaced apart and parallel to the first scraper, a sliding groove is provided on the rotating seat, a matching rod is provided on the second scraper, the matching rod is slidably fitted in the sliding groove, and the second scraper is connected to the rotating seat through a first elastic member.

[0011] Beneficial effect: The first elastic member is always in a stretched state, thereby applying a pulling force toward the first scraper to the second scraper, ensuring that the first scraper and the second scraper can be in close contact with the fan blade.

[0012] Preferably, a limiting groove is provided on the movable ring, and a limiting block is provided in the limiting groove. One end of the limiting block is tightly attached to the side wall of the limiting groove, and the other end thereof is a slope structure, and there is a gap between the slope structure and the other end side wall of the limiting groove. The matching rod can pass through the rotating seat and extend into the limiting groove, and stop with the limiting block. When the rotating seat rotates relative to the movable ring, the matching rod can move along the limiting groove.

[0013] Beneficial effect: In the initial state, the matching rod is stopped against the limit block, so that the blades of the rotating seat can extend between the first scraper and the second scraper when the rotating seat rotates. When the rotating seat rotates to change the first scraper and the second scraper from being parallel to the fan blades to being perpendicular to the fan blades, the matching rod moves along the limit block and gradually approaches the inclined end of the limit block. Under the action of the first elastic member, the end of the matching rod always stops against the limit block. When the matching rod moves to the inclined end of the limit block, the matching rod moves obliquely along the inclined surface of the limit block, thereby reducing the gap between the second scraper and the first scraper, until the first scraper and the second scraper are both in close contact with the fan blades.

[0014] Preferably, a third scraper is provided at the end of the second scraper, and the third scraper is slidably matched with the second scraper. The third scraper is connected to the second scraper through a second elastic member, and the third scraper can stop against the first scraper, so that a cleaning groove is formed between the first scraper, the second scraper, the third scraper and the rotating seat.

[0015] The effect is that the third scraper can scrape the side wall of the fan blade to prevent the generation of cleaning dead corners.

[0016] Preferably, the water storage box is slidably fitted on the first scraper or the second scraper, and is connected to the first scraper or the second scraper through a third elastic member, and a first connecting plate and a second connecting plate are provided on both sides of the first scraper and the second scraper, and the multiple nozzles are divided into four groups, and are respectively distributed on the two first connecting plates and the two second connecting plates at intervals, and two groups of connecting ports are respectively provided on both sides of the water storage box, and the two groups of connecting ports correspond to the two groups of nozzles on the first connecting plate and the second connecting plate, and the water storage box can be connected with the nozzles through the connecting ports.

[0017] The effect is that: under normal circumstances, the third elastic member is in a natural state, at which time the water storage box is connected to the nozzle on the first connecting plate. After the first scraper and the second scraper scrape the blades, the nozzle on the first connecting plate sprays water, thereby flushing the areas on the fan blades where dust and impurities have been scraped off to prevent dust and impurities from remaining. When the movable ring moves inward to the limit and stops moving inward, the water storage box is squeezed to overcome the elastic force of the third elastic member and move relative to the first scraper or the second scraper, so that the water storage box is connected to the nozzle on the second connecting plate, and the nozzle on the second connecting plate sprays water, thereby flushing away the dust gathered between the first scraper and the second scraper and the fan blades during the scraping process, ensuring the cleanliness of the first scraper and the second scraper.

[0018] Preferably, a first stopper and a second stopper are respectively provided on both sides of the water storage box, and the first stopper and the second stopper can abut against the first scraper or the second scraper, thereby limiting the movement range of the water storage box.

[0021] Preferably, the rotating seat, the first scraper, the second scraper and the third scraper are all provided with rubber pads.

[0022] By adopting the above technical solution, the beneficial effects of the present invention are: According to the industrial air-conditioning cooling machine of the present invention, when the fan is working normally, the first scraper and the second scraper are spaced apart and parallel to the fan blades. When the fan stops, the fan blades stop at a fixed position. At this time, the fan blades are located next to the cleaning device. The rotating seat is driven to rotate 90 degrees by the rotating mechanism, so that the first scraper and the second scraper are perpendicular to the fan blades, and the first scraper and the second scraper are in close contact with the fan blades. When the driving mechanism drives the movable ring to move inward along the axial direction of the fan housing, the first scraper and the second scraper can scrape off the dust and impurities on the fan blades.

A threaded hole and a matching hole are provided on the movable ring 1. The movable ring 1 is threadedly matched with the screw rod 22 through the threaded hole, and is also slidingly matched with the guide rod 23 through the matching hole. When the second driving component 41 drives the screw rod 22 to rotate, the screw rod 22 drives the movable ring 1 to move axially along the fan housing 201. The guide rod 23 is used to prevent the movable ring 1 from rotating, and can also prevent the movable ring 1 from tilting during movement.

[0040] like Figures 5 to 7 As shown, the moving ring 1 is provided with a plurality of mating seats 101 spaced apart along its circumference, and each mating seat 101 is rotatably mated with a rotating seat 3. The number of rotating seats 3 is the same as the number of blades 2022 in each set of fan blades, and each rotating seat 3 corresponds to a blade 2022. The moving ring 1 is provided with a rotating mechanism, which includes a driving ring 42, a first driving member 21, a rotating shaft 43, a cam 44 and a connecting rod 45. The moving ring 1 is a hollow structure, and the driving ring 42 is slidably fitted in the moving ring 1. The driving ring 42 can move along the axial direction of the moving ring 1. The first driving member 21 is fixedly provided on the moving ring 1. The first driving member 21 is an electric push rod, and its output end is fixedly connected to the driving ring 42.

One end of connecting rod 45 is hinged to the small-diameter end of cam 44, and the other end of connecting rod 45 is hinged to drive ring 42. The width of the opening is greater than that of connecting rod 45, allowing connecting rod 45 to swing within the opening. When drive ring 42 moves within the movable base, it drives cam 44 to rotate via connecting rod 45, and cam 44 drives rotating base 3 to rotate about rotating shaft 43 via rotating shaft 43.

[0041] like Figure 5 、 Figures 7 to 11As shown, the first scraper 5 is fixedly connected to the bottom end of the rotating seat 3, and a sliding groove is provided on the rotating seat 3, which passes through the rotating seat 3. A matching rod 61 is fixedly provided on the second scraper 6, and the matching rod 61 slides in the sliding groove. The second scraper 6 is elastically connected to the rotating seat 3 through a first elastic member 62. The first elastic member 62 is a spring, one end of which is fixedly connected to the second scraper 6, and the other end is fixedly connected to the rotating seat 3. The second scraper 6 slides with the rotating seat 3 and is distributed parallel to the first scraper 5. The matching rod 61 can move along the sliding groove in the sliding groove, so that the second scraper 6 can approach or move away from the first scraper 5. A limiting groove 1011 is provided on the matching seat 101. The limiting groove 1011 is an arc-shaped groove. A limiting block 1012 is provided in the limiting groove 1011. The limiting block 1012 is an arc-shaped structure. Its curvature is the same as the curvature of the matching difference. One end of the limiting block 1012 is in close contact with the side wall of the limiting groove 1011, and the other end is a slope structure. There is a gap between the slope structure and the other end side wall of the limiting groove 1011. The first elastic member 62 is always in a stretched state. In the state, under normal circumstances, the end of the matching rod 61 stops at the limit block 1012, thereby ensuring that the first scraper 5 and the second scraper 6 are away from each other. When the rotating seat 3 rotates, the matching rod 61 moves along the limit block 1012. When the matching rod 61 moves to the inclined end of the limit block 1012, the matching rod 61 moves along the inclined end of the limit block 1012. Under the action of the contraction elastic force of the first elastic member 62, the second scraper 6 gradually approaches the first scraper 5.

[0042] like Figures 8 to 11 As shown, the second scraper 6 is also provided with a third scraper 7, and the second scraper 6 is provided with a mounting groove, which extends along the length direction of the second scraper 6. A mounting rod 71 is fixedly provided on the third scraper 7, and the mounting rod 71 is slidably fitted in the mounting groove. A second elastic member 72 is provided between the mounting rod 71 and the mounting groove. The second elastic member 72 is a spring, and the mounting rod 71 is a hollow rod.

The wall is fixedly connected, and the third scraper 7 is vertically distributed with the second scraper 6. When the second scraper 6 moves toward the first scraper 5 to the limit, the third scraper 7 stops with the first scraper 5. At this time, a rectangular cleaning groove can be formed between the rotating seat 3, the first scraper 5, the second scraper 6 and the third scraper 7. The cleaning groove can be tightly attached to the peripheral side of the blade 2022. The rotating seat 3, the first scraper 5, the second scraper 6 and the third scraper 7 are all provided with rubber pads, so that the side walls of the cleaning groove are covered with rubber pads, and the rubber pads can be tightly attached to the blade 2022.

[0043] like Figures 8 to 10As shown, the first scraper 5 and the second scraper 6 are both provided with matching grooves, and the two matching grooves are symmetrically distributed. A water storage box 8 is slidably fitted in each matching groove. A first stop 82 and a second stop 83 are respectively provided on both sides of the water storage box 8. The first stop 82 and the second stop 83 are spaced apart. The first stop 82 can stop against the corresponding side wall of the matching groove, and the second stop 83 can stop against the corresponding side wall on the other side of the matching groove. The water storage box 8 is elastically connected to the first scraper 5 or the second scraper 6 through a third elastic member 81. The third elastic member 81 is a spring. One end of the third elastic member 81 is fixedly connected to the first stop 82, and the other end thereof is fixedly connected to the first scraper 5 or the second scraper 6. The water storage box 8 can move along the width direction of the first scraper 5 or the second scraper 6. The first stop 82 and the second stop 83 can limit the moving range of the water storage box 8. A first connecting plate 10 and a second connecting plate 11 are provided on either side of the first scraper 5 and the second scraper 6, respectively. The plurality of nozzles 9 are divided into four groups, with each first connecting plate 10 and second connecting plate 11 provided with a group of nozzles 9.

The water inlet 84 communicates with the water storage chamber within the mobile ring 1 via a hose, and the water storage chamber within the mobile ring 1 communicates with an external water tank via a water pipe.

[0044] like Figure 2 As shown, a drain outlet 2011 is also provided at the bottom of the fan housing 201, and a closing plate 12 is slidably fitted at the drain outlet 2011. The closing plate 12 is slidably fitted with the fan housing 201 through a fourth elastic member 121. The fourth elastic member 121 is a spring. One end of the fourth elastic member 121 is fixedly connected to the closing plate 12, and the other end thereof is fixedly connected to the fan housing 201.

[0045] The implementation principle of the industrial air conditioning cooling machine of the embodiment of the present invention is: When the fan 200 is working normally, the cleaning device remains stationary and does not contact the fan blades to avoid affecting the air supply of the fan blades. When the fan blades stop rotating, the fan blades will stop at a fixed position. At this time, the fan blades are located next to the cleaning device. Under the action of the contraction elastic force of the first elastic member 62, the matching rod 61 and the top surface of the limit block 1012 stop, so that there is a gap between the third scraper 7 and the first scraper 5.When the blade 2022 needs to be cleaned, the first driving member 21 drives the driving ring 42 to move outward, and the driving ring 42 pulls the cam 44 through the connecting rod 45, so that the cam 44 rotates 90 degrees, and the cam 44 drives the rotating seat 3 to rotate through the rotating shaft 43, so that the first scraper 5 and the second scraper 6 are changed from being parallel to the blade 2022 to being perpendicular to the blade 2022. At the same time, the blade 2022 is located between the first scraper 5 and the second scraper 6. During the rotation of the rotating seat 3, the matching rod 61 moves along the limit block 1012 and gradually approaches the inclined end of the limit block 1012. When the matching rod 61 moves to the inclined end of the limit block 1012, under the action of the contraction elastic force of the first elastic member 62 , the end of the matching rod 61 moves along the inclined end of the limit block 1012, so that the second scraper 6 gradually approaches the first scraper 5. When the matching rod 61 is out of contact with the inclined end of the limit block 1012 and stops at the bottom surface of the limit groove 1011, the third scraper 7 stops at the first scraper 5. At this time, under the contraction elastic force of the first elastic member 62, the rubber pads on the first scraper 5 and the second scraper 6 are tightly attached to the blade 2022. Under the contraction elastic force of the second elastic member 72, the rubber pads on the third scraper 7 and the rubber pads on the rotating seat 3 are respectively tightly attached to the two side walls of the blade 2022. Then the first driving member 21 drives the screw rod 22 to rotate, thereby driving the moving ring 1 to move inward. The moving ring 1 moves inward During the movement, the rubber pads on the rotating seat 3, the first scraper 5, the second scraper 6 and the third scraper 7 can scrape off the dust and impurities attached to the blades 2022, and the scraped impurities are collected at the corner formed by the inner side walls of the rotating seat 3, the first scraper 5, the second scraper 6 and the third scraper 7 and the blades 2022. During the inward movement of the mobile ring 1, the third elastic member 81 is in a natural state. At this time, the water storage box 8 is connected with the nozzle 9 on the first connecting plate 10. At this time, the external water pump pumps water into the mobile ring 1, and the water in the mobile ring 1 enters the water storage box 8 through the hose, and is then sprayed out through the nozzle 9 on the first connecting plate 10, thereby cleaning the rotating seat 3, the first scraper 5, the second scraper 6 and the third The scraper 7 rinses the blades 2022 after scraping to prevent dust and impurities from remaining on the blades 2022. During the inward movement of the movable ring 1, the water storage box 8 gradually approaches the inner fixed ring 2021 and stops with the fixed ring 2021, so that the water storage box 8 overcomes the elastic force of the third elastic member 81 and moves outward relative to the first scraper 5 or the second scraper 6. When the movable ring 1 stops moving, the water storage box 8 is connected to the spray hole on the second connecting plate 11. At this time, the spray hole on the second connecting plate 11 sprays water to wash away the dust and impurities gathered at the corner between the inner wall of the rotating seat 3, the first scraper 5, the second scraper 6 and the third scraper 7 and the blades 2022, thereby realizing self-cleaning of the cleaning device.

[0046] During the cleaning process, sewage mixed with dust will gather at the bottom of the fan housing 201. During the inward movement of the movable ring 1, the cleaning device located at the bottom of the movable ring 1 can stop with the closing plate 12 and push the closing plate 12 to overcome the elastic force of the fourth elastic member 121 to move, thereby opening the drain port 2011, and the sewage mixed with dust can be discharged from the fan housing 201 through the drain port 2011.

[0047] After cleaning is completed, the first driving member 21 drives the screw rod 22 to rotate in the opposite direction, thereby moving the movable ring 1 outward. When the movable ring 1 moves outward to the limit, the second driving member 41 drives the driving ring 42 to move inward. The driving ring 42 pushes the cam 44 to rotate 90 degrees in the opposite direction through the connecting rod 45. The cam 44 drives the rotating seat 3 to rotate 90 degrees in the opposite direction. During the rotation of the rotating seat 3, the matching rod 61 moves along the top surface of the limit block 1012 under the action of the first elastic member 62, so that the second scraper 6 gradually moves away from the first scraper 5, and the third scraper 7 is out of contact with the first scraper 5. The blade 2022 can be separated from the cleaning groove from the gap between the third scraper 7 and the first scraper 5. When the rotating seat 3 stops rotating, the cleaning device is reset.

[0048] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
