Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning units, and more particularly to an energy-saving and environment-friendly air-conditioning unit for a communication base station. Background Art

[0002] Energy-saving and environmentally friendly air conditioning units for communication base stations are precision, specialized air conditioning equipment designed specifically for base station computer rooms. They control the temperature and humidity within the base station room, ensuring stable and reliable operation of communication equipment. Featuring a highly reliable design and equipped with cooling, heating, dehumidification, and humidification functions, these air conditioners provide the ideal temperature and humidity environment for the base station room around the clock, ensuring the proper operation of communication equipment and extending its service life.

[0003] Currently, in the prior art, for example, publication number CN116017962A discloses an energy-saving base station air conditioner, comprising an air conditioner housing, an air heat exchanger, an indoor fan, an outdoor fan, an indoor air intake mechanism, an outdoor air intake mechanism, and a condenser, wherein an air conditioner inner housing is disposed within the air conditioner housing. Although this base station air conditioner reduces power consumption and achieves energy-saving effects, the outdoor air intake duct is located at the lower end of the back of the air conditioner housing, which reduces the height of the air intake duct relative to the outdoor ground. The dust content in the air closer to the ground is high, which easily allows more dust to enter the air intake duct along with the air. Although a filter is provided in the air intake duct to filter dust, such a large amount of dust adsorbed on the outside of the filter still reduces its filtering effect, thereby affecting the normal air intake. Although this problem can be solved by regularly cleaning or replacing the filter, since communication base stations are generally located in relatively remote environments and are distributed in large numbers, the distance between each communication base station is large, and they are unattended for long periods of time, the workload and difficulty of cleaning and replacing the filter are high, and the manpower and material costs required are high. Summary of the Invention

[0004] The purpose of the present invention is to provide an energy-saving and environment-friendly air-conditioning unit for a communication base station to solve the above-mentioned technical problems.

The second gear is rotatably installed on the inner side of the air inlet duct, and one side of it is engaged with the first gear. The rotating disk is fixedly installed on one side of the second gear. The bottom of the skateboard is slidingly connected to the inner bottom wall of the air inlet duct, one end of the rocker arm is hinged to the rotating disk, and the other end is hinged to the top of the skateboard. The tooth groove segment is arranged at the top of the skateboard, the third gear is rotatably connected to one side of the inner wall of the air inlet duct, and its outer side is engaged with the tooth groove segment.

[0013] As a further optimization scheme of the present invention, the sliding contact part includes a cleaning scraper and two connecting springs. The two ends of the cleaning scraper are respectively slidably connected to the two sides of the inner wall of the air inlet duct. The two connecting springs are respectively installed between the two ends of the cleaning scraper and the inner wall of the air inlet duct. One side of the cleaning scraper contacts the air inlet side of the filter screen, and the top and bottom of the end of the cleaning scraper in contact with the filter screen are provided with a groove.

[0014] As a further optimization scheme of the present invention, the movable traction part includes a winding wheel, a traction rope and two traction pulleys. The winding wheel is fixedly connected to one side of the third gear. The two traction pulleys are symmetrically distributed on both sides of the filter screen.

[0018] The beneficial effects of the present invention are:

[0019] The air intake assembly provided in the present invention can not only realize the adaptive switching of the air intake mode, but also can synchronously realize a scraping and cleaning of the dust on the surface of the filter screen during the switching process. By coordinating the transmission of the cleaning part, the driving part and the blocking part, on the one hand, the filter screen can be cleaned regularly to maintain the filtering effect of the filter screen. On the other hand, there is no need to set up an additional driving source and a control program to realize the automatic cleaning operation of the cleaning part. Therefore, the power consumption of the air-conditioning unit will not be further increased. The function of automatically and regularly cleaning the filter screen is realized without increasing the power consumption of the original air-conditioning unit, which greatly reduces the difficulty of cleaning the filter screen and reduces the required manpower and material costs. It can be widely promoted and used. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0031] Please refer to Figure 1 and Figure 2 An energy-saving and environmentally friendly air-conditioning unit for a communication base station includes: an air-conditioning case 1, a refrigeration mechanism 2, an outdoor air circulation mechanism 3, an indoor air circulation mechanism 4 and an air heat exchanger 5. The refrigeration mechanism 2 is used to cool the internal environment of the communication base station room, and includes a compressor, a condenser and other related components. The indoor air circulation mechanism 4 is mainly used to realize air circulation in the communication base station room. Since the refrigeration mechanism 2 and the indoor air circulation mechanism 4 are both conventional technical means in this field, their working principles and related structural components are not described in detail here.

[0032] Please refer to Figures 2 to 3The outdoor air circulation mechanism 3 includes an air outlet component 31 and an air inlet component 32 respectively installed at the upper and lower ends of the back of the air-conditioning case 1, wherein the air outlet component 31 includes an air outlet duct 311 and an outdoor air outlet fan 312, and the air outlet duct 311 can be detachably installed at the upper end of the back of the air-conditioning case 1. The input end of the outdoor air outlet fan 312 is connected to the air heat exchanger 5, and its output end is connected to the air outlet duct 311. The air inlet assembly 32 includes an air inlet duct 321, a filter 322, a blocking member 323, a driving member 324 and a dust cleaning member 325. The air inlet duct 321 is provided with two air inlets 326 symmetrically distributed in the upper and lower directions at one end close to the air conditioning case 1. The two air inlets 326 are respectively connected to the refrigeration mechanism 2 and the air heat exchanger 5. The blocking member 323 is located between the two air inlets 326, and one side thereof is slidably connected to the inner wall of the air inlet duct 321. The driving end of the driving member 324 is connected to the blocking member 323, and the blocking member 323 is driven by the driving member 324 to move and align with the corresponding air inlet 326. The air inlet 326 is blocked, and the air inlet mode of the air inlet duct 321 is switched; the filter 322 is fixedly installed on the inner side of the air inlet duct 321, and the dust cleaning part 325 includes a sliding contact part and a movable traction part, the sliding contact part is connected to the movable traction part, the sliding contact part is in contact with the air inlet side of the filter 322, and the movable traction part is connected to the driving end of the driving part 324. In the process of the driving part 324 driving the blocking part 323 to move, the movable traction part is synchronously driven by the driving part 324, driving the sliding contact part to slide along the air inlet side of the filter 322, scraping and cleaning the dust adsorbed on the filter 322 once.

[0033] Please refer to Figure 3 The air inlet duct 321 is removably mounted at the lower end of the back of the air conditioning case 1. The air inlet duct 321 is a rectangular duct. The end of the air inlet duct 321 away from the air conditioning case 1 is equipped with linearly evenly distributed louvers. The filter 322 is removably mounted on the inner side of the air inlet duct 321, near the louvers. Placing the filter 322 near the louvers allows air to be filtered directly after entering the air inlet duct, preventing excessive dust from entering the inner wall of the air inlet duct. The air inlet 326 has a rectangular cross-section. The blocking member 323 is a rectangular plate larger than the air inlet 326. When the rectangular plate is positioned between the two air inlets 326, both air inlets 326 are fully open.

[0034] Please refer to Figure 2 and Figure 3 It should be noted that the energy-saving and cooling mechanism of the above air-conditioning unit is: Figure 2The operating mode shown in the figure is a mode in which the refrigeration mechanism 2 and the air heat exchanger 5 jointly realize cooling. This mode is suitable for the situation where the outdoor temperature is lower than the temperature inside the base station and higher than the set low temperature threshold, and the temperature inside the base station cannot be maintained by the cooling effect of the air heat exchanger 5 alone. At this time, since the two air inlets 326 are in the open state, the outside air can enter the refrigeration mechanism 2 and the air heat exchanger 5 respectively to realize the cooling function inside the base station. When the outdoor ambient temperature changes and the operating mode of the air-conditioning base needs to be adjusted, if the outdoor ambient temperature continues to rise, the air exchanger 5 will be turned off. The cooling effect of the heat exchanger 5 cannot be used, and the air conditioner needs to be switched to a mode in which the cooling mechanism 2 performs cooling alone. At this time, the air inlet 326 connected to the air heat exchanger 5 needs to be closed, so that the outside air can enter through the air inlet 326 connected to the cooling mechanism 2. When the outdoor temperature continues to drop and falls below the set low temperature threshold, the air heat exchanger 5 can be used alone to perform cooling to meet the indoor cooling needs of the base station. Therefore, the air inlet 326 connected to the air heat exchanger 5 needs to be opened, and the air inlet 326 connected to the cooling mechanism 2 needs to be closed. In this way, the air conditioning unit can adjust its cooling mode according to the change of the outdoor ambient temperature to reduce its power consumption and achieve energy saving function.

[0035] Based on the above situation, in the process of switching the air conditioning unit to the cooling mode, the present invention can realize the automatic dust cleaning function of the filter 322 synchronously. The specific process is: through the operation of the driving member 324, the blocking member 323 can be driven to move to the corresponding air inlet 326 position. At the same time, the movable traction part can drive the sliding contact part to slide along the air inlet side of the filter 322 under the driving action of the driving member 324. The end of the sliding contact part contacts the dust, and the dust adsorbed on the filter 322 can be scraped off. After the blocking member 323 completely blocks the air inlet 326, the driving member 324 stops driving, and the blocking member 323 and the sliding contact part are no longer active. In this way, the air inlet mode of the air conditioning unit is switched. During the process, the dust on the surface of the filter 322 is scraped and cleaned at the same time. Since the cleaning operation of the filter 322 does not need to be performed frequently, the present invention uses the cleaning member 325, the driving member 324 and the blocking member 323 in conjunction with each other. On the one hand, it can ensure that the filter 322 is cleaned regularly, and on the other hand, there is no need to set up an additional driving source and a control program to realize the automatic cleaning operation of the cleaning member 325. Therefore, the power consumption of the air-conditioning unit will not be further increased. The function of automatically and regularly cleaning the filter 322 is realized without increasing the power consumption of the original air-conditioning unit, which greatly reduces the difficulty of cleaning the filter 322 and the required manpower and material costs, and can be widely promoted and used.

[0036] Please refer to Figures 4 to 6The driving member 324 includes a driving motor 3241, a first driving part and a second driving part. The fixed end of the driving motor 3241 is fixed to the inner wall of the air inlet duct 321. The rotating end of the driving motor 3241 is connected to the blocking member 323 through the first driving part. The driving motor 3241 rotates, so that the first driving part drives the blocking member 323 to slide and rise linearly. The first driving part is connected to the movable traction part through the second driving part. The first driving part drives the second driving part to move, so that the second driving part drives the sliding contact part to slide linearly.

[0037] The first driving part includes a first gear 3242 and a tooth plate 3243 . The first gear 3242 is fixedly connected to the rotating end of the driving motor 3241 . The tooth plate 3243 is fixedly installed in the middle position of one side of the blocking member 323 . One side of the first gear 3242 is meshed with the tooth plate 3243 . The second driving unit includes a second gear 3244, a rotating disk 3245, a rocker arm 3246, a slide plate 3247, a third gear 3248 and a toothed segment 3249. The second gear 3244 is rotatably mounted on the inner side of the air inlet duct 321, and one side of the second gear 3244 is meshed with the first gear 3242. The diameter of the second gear 3244 is smaller than that of the first gear 3242, so that the two can rotate at a differential speed to increase the rotation amplitude of the rotating disk 3245. The rotating disk 3245 is fixedly mounted on one side of the second gear 3244. The bottom of the slide plate 3247 is slidably connected to the inner bottom wall of the air inlet duct 321. One end of the rocker arm 3246 is hinged to the rotating disk 3245, and the other end thereof is hinged to the top end of the slide plate 3247. The toothed segment 3249 is set at the top end of the slide plate 3247. The third gear 3248 is rotatably connected to one side of the inner wall of the air inlet duct 321, and its outer side is meshed with the toothed segment 3249. One side of the third gear 3248 is connected to the traction movable part.

[0038] It should be noted that when the driving member 324 is in use, the first gear 3242 can be driven to rotate by the driving motor 3241. Under the driving action of the rotation of the first gear 3242, the tooth plate 3243 begins to slide and translate in the corresponding direction together with the blocking member 323. When the blocking member 323 blocks the air inlet 326 in the corresponding direction, the driving motor 3241 stops rotating, completing the switching of the air intake mode of the air-conditioning unit. In this process, the second gear 3244 synchronously rotates with the first gear 3242, causing the rotating disk 3245 to start driving the swing rod 3246 to move, and the slide plate 3247 is subjected to the pulling force of the swing rod 3246 and begins to move in the air inlet duct 321. The gear 3248 is rotated by the tooth groove section 3249, and the third gear 3248 is driven by the rotation of the third gear 3248 to drive the movable traction part to slide the sliding contact part, so as to realize the synchronous cleaning operation of the filter 322. The driving part 324 can realize the blocking function of the corresponding air inlet 326 when used in conjunction with the blocking part 323. When used in conjunction with the cleaning part 325, it can realize the function of automatically cleaning the filter 322. No matter which blocking state the blocking part 323 moves to, the cleaning part 325 completes a cleaning action under the driving action of the driving part 324, so that the cleaning part 325 is well adapted to the movement mode of the blocking part 323.

[0039] Please refer to Figures 7 to 9 There are two sliding contact parts, two movable traction parts, two third gears 3248, and two tooth groove sections 3249. The two sliding contact parts are symmetrically distributed in the middle of the air inlet side of the filter 322. The two sliding contact parts are respectively connected to the two movable traction parts, and the two third gears 3248 are respectively connected to the two movable traction parts. The sliding contact part includes a cleaning scraper 3251 and two connecting springs 3252. The ends of the cleaning scraper 3251 are respectively slidably connected to the two sides of the inner wall of the air inlet duct 321. The two connecting springs 3252 are respectively installed between the ends of the cleaning scraper 3251 and the inner wall of the air inlet duct. One side of the cleaning scraper 3251 contacts the air inlet side of the filter 322. The top and bottom of the end of the cleaning scraper 3251 that contacts the filter 322 are both grooved. The movable traction part includes a winding wheel 3253, a traction rope 3254 and two traction pulleys 3255. The winding wheel 3253 is fixedly connected to one side of the third gear 3248. The two traction pulleys 3255 are symmetrically distributed on both sides of the filter screen 322. The two traction pulleys 3255 are both rotatably connected to the inner side of the air inlet duct 321. One end of the traction rope 3254 is wrapped around the winding wheel 3253, and the other end thereof is fixed to one side of the cleaning scraper 3251. The outer sides of the traction rope 3254 are in rolling contact with the two traction pulleys 3255 respectively.

[0040] It should be noted that when the above-mentioned cleaning member 325 is used to clean the filter screen 322, in the process of the driving member 324 driving the blocking member 323 to move, the positive rotation of the third gear 3248 can drive the corresponding winding wheel 3253 to rotate synchronously, so that the winding wheel 3253 begins to reel in the traction rope 3254 wound thereon, and the traction rope 3254 subjected to tension generates a pulling force on the cleaning scraper 3251 under the transmission action of the two traction pulleys 3255, and finally causes the two cleaning scrapers 3251 to gradually slide away, respectively cleaning the upper end and the lower end of one side of the filter screen 322, and the cleaning scrapers 3251 are moved away from each other. During the sliding process, the two connecting springs 3252 connected thereto are squeezed and contracted synchronously. When the driving member 324 stops driving, the two cleaning scrapers 3251 are respectively moved to the upper and lower ends of one side of the filter 322, so that the dust adsorbed on the air inlet surface of the filter 322 can be fully scraped and cleaned. When the driving member 324 drives the blocking member 323 to move next time, the third gear 3248 can be rotated in the opposite direction, thereby causing the reel 3253 to synchronously lengthen the traction rope 3254. The cleaning scrapers 3251 slide back to their original position under the elastic force of the connecting springs 3252, and clean the air inlet surface of the filter 322 again.

[0041] The above describes an embodiment of this specific implementation method, but this embodiment is not limited to the above specific implementation method. The above specific implementation method is merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
