Description

Technical Field

[0001] The present invention relates to the technical field of air - conditioning ventilation protection, and particularly to a ventilation protection and filtration component for a central air - conditioning system. Background Art

[0002] A central air - conditioning system is a system that uniformly adjusts and controls the air environment of large buildings or multiple areas through centralized equipment. Compared with traditional split - type air conditioners (such as wall - mounted and cabinet - type air conditioners), it has the characteristics of large coverage area, higher energy efficiency, stronger comfort, and better aesthetics, and is widely used in large public buildings such as shopping malls, office buildings, hotels, hospitals, factories, gymnasiums, etc. and high - end residences. The most commonly used part of the central air - conditioning system is the refrigeration system. Different from household wall - mounted air conditioners, the outdoor unit of the central air - conditioning system is set at the top of the building and consists of structures such as a compressor, a condenser, a fresh - air system, and a cooling tower. After the compressor and the condenser complete the heat exchange, hot water is output to the cooling tower. Through the cooling tower, the heat in the water is exchanged with air through spraying, and the cooled cold water is then transported to the compressor and the condenser to cool them.

[0003] The central air - conditioning system is set at the top of the building and in contact with the outside world. A large amount of dust will accumulate in the ventilation system of the cooling tower, affecting the cooling effect of the cooling tower. After long - term use, most filters are blocked by dust, resulting in low efficiency of heat exchange between spraying and air, poor refrigeration effect of the central air - conditioning system, and thus affecting the air - conditioning refrigeration of the entire building. However, since the building air - conditioner is a public item and cannot be turned off at will, most manual cleanings are carried out in the early morning or at night, increasing the labor cost. To fundamentally solve the problem of dust accumulation in the above - mentioned filtration system, the following solution is proposed, specifically a ventilation protection and filtration component for a central air - conditioning system. Summary of the Invention

[0004] To solve the above - mentioned technical problems, the present invention provides a ventilation protection and filtration component for a central air - conditioning system, including a main body mechanism. The main body mechanism further includes a cooling - tower shell, and further includes:

[0005] The main body mechanism, which is a cooling tower for cooling and providing cold air for the central air - conditioning system;

[0006] The filtering mechanism, which is fixedly connected to the inner wall of the main body mechanism for filtering dust and maintaining normal ventilation;

[0007] The circulating mechanism, which is fixedly connected to the top of the main body mechanism for circulating air flow to blow away fine sediment;

[0008] The inner wall of the cooling tower housing is fixedly connected with a mounting frame. The inner wall of the mounting frame is fixedly connected with a number of fixing plates. The inner wall of the mounting frame is fixedly connected with a motor. The output shaft of the motor is rotationally connected with a belt. One end of the belt away from the motor is rotationally connected with a rotating shaft. The two ends of the rotating shaft away from the belt are fixedly connected with bevel gear one. The outer wall of the rotating shaft is rotationally connected with the inner walls of a number of fixing plates. Before use, install the filtering mechanism and the circulation mechanism in the condenser tower of the central air-conditioning ventilation system, so that the air flow passes through this equipment when the condenser tower works. Connect the power supply of this equipment and the condenser, and start the equipment. After starting the equipment, the air flow will enter the equipment through the filtering mechanism on both sides of the main body mechanism, and the heat in the equipment will be taken away by the circulating air component.

[0009] Preferably, the main body mechanism includes:

[0010] The main body component, which is fixedly connected to the inner wall of the main body mechanism and is used to provide protection for the internal equipment;

[0011] The internal component, which is fixedly connected to the inner wall of the main body mechanism and cools down the central air-conditioning coolant.

[0012] Preferably, the filtering mechanism includes:

[0013] The filtering component, which is fixedly connected to the inner wall of the main body mechanism and is used to filter sediment;

[0014] The connection component, which is fixedly connected to the inner wall of the filtering component and is used to drive the connection component.

[0015] Preferably, the circulation mechanism includes:

[0016] The cleaning component, which is fixedly connected inside the filtering mechanism and is used to clean the sediment filtered by the filtering component;

[0017] The circulating air component, which is fixedly connected to the top of the main body mechanism and is used to keep the ventilation smooth while cooling the equipment.

[0018] Preferably, the main body component includes ventilation grilles fixedly connected to both sides of the outer wall of the cooling tower housing.

[0019] Preferably, the internal component includes a spray system fixedly connected inside the cooling tower housing, and a sedimentation chamber is provided on the inner wall of the cooling tower housing.

[0020] Preferably, the filtering component includes a filtering grille net fixedly connected to the outer wall of the mounting frame, and the outer wall of the filtering grille net is fixedly connected to the inner wall of the cooling tower housing.

[0021] Preferably, the connecting component includes a first large bevel gear rotatably connected to the inner wall of the mounting frame. The outer wall of the first large bevel gear is meshed with the outer wall of the first bevel gear. The bottom of the first large bevel gear is fixedly connected to a threaded rod. The end of the threaded rod away from the first large bevel gear is rotatably connected to the inner wall of the cooling tower housing. The outer wall of the threaded rod is meshed with a slider. To address the problem of filter ash accumulation affecting refrigeration, when air flows through the device, the air inlet grille and the filter grille will block most foreign objects, such as leaves and dust. When the filter grille is used for a long time, by controlling the start of the motor, the rotating shaft rotates, causing the first large bevel gear meshed with the first bevel gear to rotate. The lower end of the first large bevel gear is fixedly connected to a threaded rod. When the threaded rod rotates, the slider meshed with the threaded rod will be restricted from spinning between the filter grille and the air inlet grille due to the limit, and thus is controlled by the thread when the threaded rod rotates, causing the fixedly connected cleaning component to move downward. When the scraper fixed to the outer wall of the slider moves downward, the scraper will scrape the caked dust on the surface of the filter grille, thereby restoring the ventilation and filtering function of the filter grille and avoiding the problem of low cooling efficiency of the central air conditioner caused by the blockage of the filtration system.

[0022] Preferably, the cleaning component includes a scraper fixedly connected to the outer wall of the slider. The outer wall of the scraper is attached to the outer wall of the filter grille. A grid scraper is rotatably connected to the outer wall of the scraper. Rubber contacts are provided on the outer wall of the grid scraper. A spring is fixedly connected to the inner wall of the grid scraper. The end of the spring away from the grid scraper is fixedly connected to the outer wall of the scraper. Using the force of the above-mentioned scraper moving up and down, when the scraper scrapes, since the grid scraper is connected by a spring, it will not touch the surface of the filter grille. After the grid scraper finishes scraping, it will move upward and reset. During this process, due to the special setting of the grid scraper, when moving upward, the side with the spring fixed on the outer surface of the grid scraper will be subject to greater air resistance, causing the grid scraper to rotate at the rotational connection with the scraper, so that the rubber contacts come into contact with the outside of the filter grille. When the rubber contacts come into contact with the grid of the filter grille and the scraper drives the grid scraper to move upward, the dust in the grid of the filter grille will be driven upward by the rubber contacts, thus avoiding the problem that dust accumulates in the grid and is difficult to remove, resulting in poor ventilation and affecting heat dissipation.

[0023] Preferably, the circulating air component includes a partition net fixedly connected to the inner wall of the cooling tower housing. A fan is provided at the top of the cooling tower housing. A number of brushes are fixedly connected to the outer wall of the partition net. By using the force generated by the rotation of the fan, a sedimentation chamber is provided in the condensation tower to sediment the dust and debris entering the water flow. However, to avoid excessive dust, a filtration system is provided. When the air flow passes through the filtration system, water vapor will be generated due to the spray system provided inside the condensation tower. A small amount of dust will adhere to the fan due to the water vapor under the drive of the air flow. When the fan rotates, it will pass by the brushes. Through the continuous rotation of the fan, the brushes will continuously touch the fan, so that the dust cannot adhere to the fan, avoiding a large amount of dust adhering to the fan due to water vapor and affecting the ventilation effect of the fan. By using the force of the contact between the brushes and the fan, when a small amount of dust is knocked off by the fan, because the contact between the brushes and the fan will cause the dust originally adhering to the fan to be swept off. When the swept-off dust falls downward, since the fan is always in operation, it will continuously extract the air inside the equipment and flow it outwards, causing the originally swept-off dust to be discharged outwards along with the air flow, avoiding the swept-off dust falling into the sedimentation chamber and increasing the burden on the sedimentation chamber.

[0024] The present invention has the following beneficial effects:

[0025] (1) Aiming at the problem that the filtering of accumulated dust affects refrigeration, when the filtering grille net is used for a long time, the motor is controlled to start to rotate the rotating shaft, so that the large bevel gear 1 meshed with the bevel gear 1 rotates. A threaded rod is fixedly connected to the lower end of the large bevel gear 1. When the threaded rod rotates, the slider meshed with the threaded rod will be controlled by the thread rotated when the threaded rod rotates because the rotation between the filtering grille net and the ventilation grille is restricted and cannot generate self-rotation, so that the fixedly connected cleaning component moves downward. When the scraper fixed to the outer wall of the slider moves downward, the scraper will scrape off the caked dust on the surface of the filtering grille net, thus restoring the ventilation and filtering function of the filtering grille net and avoiding the problem of low cooling efficiency of the central air conditioner caused by the blockage of the filtering system.

[0026] (2) By using the force of the up and down movement of the above-mentioned scraper, when the scraper scrapes, since the grid scraper is connected by a spring and will not touch the surface of the filtering grille net, after the grid scraper finishes scraping, it will move upward and reset. During this process, due to the special setting of the grid scraper, when moving upward, the side with the spring fixed on the outer surface of the grid scraper will be subject to a large wind resistance, causing the connection between the grid scraper and the scraper to rotate, so that the rubber contact point contacts the outside of the filtering grille net. When the rubber contact point contacts the grid of the filtering grille net and the scraper drives the grid scraper to move upward, the dust in the grid of the filtering grille net will be driven upward by the rubber contact point, thus avoiding the problem that the dust accumulates in the grid and is difficult to remove, resulting in poor ventilation effect and affecting heat dissipation.

[0027] (3) The present invention utilizes the force generated by the rotation of the fan. The condensation tower is provided with a sedimentation chamber to precipitate dust and debris entering the water flow. However, to avoid excessive dust, a filtration system is provided. When the air flow passes through the filtration system, water vapor is generated due to the spray system inside the condensation tower. A small amount of dust will adhere to the fan due to the water vapor under the drive of the air flow. When the fan rotates, it will pass by the brush. Through the continuous rotation of the fan, the brush will continuously touch the fan, thereby preventing the dust from adhering to the fan and avoiding a large amount of dust adhering to the fan due to water vapor, which affects the ventilation effect of the fan.

[0028] (4) The present invention utilizes the force of the contact between the brush and the fan. When a small amount of dust is knocked off by the fan, the dust originally adhered to the fan will be swept off due to the contact between the brush and the fan. When the swept-off dust falls downward, since the fan is always in a working state, it will continuously extract the air inside the device and flow it outwards, causing the originally swept-off dust to be discharged outwards along with the air flow, avoiding the dust falling into the sedimentation chamber after being swept off and increasing the burden on the sedimentation chamber.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1, please refer to Figures 1-6 , the present invention is a ventilation protection and filtering component for a central air-conditioning system, including a main body mechanism 1. The main body mechanism 1 further includes a cooling tower shell 111, and further includes:

[0044] The main body mechanism 1, which is a cooling tower for cooling to provide cold air for the central air-conditioning;

[0045] The filtering mechanism 2, which is fixedly connected to the inner wall of the main body mechanism 1 for filtering dust and maintaining normal ventilation;

[0046] The circulating mechanism 3, which is fixedly connected to the top of the main body mechanism 1 to circulate air flow and blow away fine sediment through the air flow;

[0047] On the inner wall of the cooling tower housing 111, there is a fixedly connected mounting frame 113. On the inner wall of the mounting frame 113, there are several fixedly connected fixing plates 213. On the inner wall of the mounting frame 113, there is a fixedly connected motor 212. The output shaft of the motor 212 is rotationally connected to a belt 215. One end of the belt 215 away from the motor 212 is rotationally connected to a rotating shaft 214. At both ends of the rotating shaft 214 away from the belt 215, there are fixedly connected bevel gears one 221. The outer wall of the rotating shaft 214 is rotationally connected to the inner walls of several fixing plates 213. Before use, install the filtering mechanism 2 and the circulating mechanism 3 in the condensation tower of the central air-conditioning ventilation system, so that the air flow passes through this equipment when the condensation tower works. Connect the power supply of this equipment and the condenser, and start the equipment. When the equipment is started, the air flow will enter the equipment through the filtering mechanism 2 on both sides of the main body mechanism 1, and the heat in the equipment will be taken away by the circulating air component 32.

[0048] The main body mechanism 1 includes:

[0049] The main body component 11, which is fixedly connected to the inner wall of the main body mechanism 1, is used to provide protection for the internal equipment;

[0050] The internal component 12, which is fixedly connected to the inner wall of the main body mechanism 1, cools the central air-conditioning coolant.

[0051] The filtering mechanism 2 includes:

[0052] The filtering component 21, which is fixedly connected to the inner wall of the main body mechanism 1, is used to filter sediment;

[0053] The connecting component 22, which is fixedly connected to the inner wall of the filtering component 21, is used to drive the connecting component.

[0054] The circulating mechanism 3 includes:

[0055] The cleaning component 31, which is fixedly connected to the inside of the filtering mechanism 2, is used to clean the sediment filtered by the filtering component 21;

[0056] The circulating air component 32, which is fixedly connected to the top of the main body mechanism 1, is used to keep the ventilation smooth while cooling the equipment.

[0057] The main body component 11 includes ventilation grilles 112 fixedly connected to both sides of the outer wall of the cooling tower housing 111.

[0058] The internal component 12 includes a spraying system 121 fixedly connected inside the cooling tower housing 111, and a sedimentation chamber 122 is provided on the inner wall of the cooling tower housing 111.

[0059] The filtering component 21 includes a filtering grille 211 fixedly connected to the outer wall of the mounting frame 113, and the outer wall of the filtering grille 211 is fixedly connected to the inner wall of the cooling tower housing 111.

[0060] The connection component 22 includes a first large bevel gear 222 rotatably connected to the inner wall of the mounting frame 113. The outer wall of the first large bevel gear 222 is meshed with the outer wall of the first bevel gear 221. A threaded rod 223 is fixedly connected to the bottom of the first large bevel gear 222. The end of the threaded rod 223 away from the first large bevel gear 222 is rotatably connected to the inner wall of the cooling tower housing 111. A slider 224 is meshed with the outer wall of the threaded rod 223. Regarding the problem that the filtering of accumulated ash affects refrigeration, when the air flow passes through the interior of the device, the ventilation grille 112 and the filtering grille 211 will block most foreign objects, such as leaves and dust. After the filtering grille 211 is used for a long time, by controlling the start of the motor 212, the rotating shaft 214 rotates, causing the first large bevel gear 222 meshed with the first bevel gear 221 to rotate. A threaded rod 223 is fixedly connected to the lower end of the first large bevel gear 222. When the threaded rod 223 rotates, the slider 224 meshed with the threaded rod 223 cannot spin between the filtering grille 211 and the ventilation grille 112 due to being restricted, and thus is controlled by the threads rotating when the threaded rod 223 rotates, causing the fixedly connected cleaning component 31 to move downward. When the scraper 311 fixed to the outer wall of the slider 224 moves downward, the scraper 311 will scrape the caked dust on the surface of the filtering grille 211, thereby restoring the ventilation and filtering function of the filtering grille 211 and avoiding the problem of low cooling efficiency of the central air conditioner caused by the blockage of the filtering system.

[0061] Example two, please refer to Figures 4-10, the present invention is a ventilation protection and filtration component for a central air-conditioning system. On the basis of Example 1, the cleaning component 31 includes a scraper 311 fixedly connected to the outer wall of the slider 224. The outer wall of the scraper 311 is in fit connection with the outer wall of the filter grille 211. A grid scraper 312 is rotatably connected to the outer wall of the scraper 311. Rubber contacts 313 are arranged on the outer wall of the grid scraper 312. A spring 314 is fixedly connected to the inner wall of the grid scraper 312. One end of the spring 314 away from the grid scraper 312 is fixedly connected to the outer wall of the scraper 311. Using the force of the up and down movement of the scraper 311, when the scraper 311 scrapes, since the grid scraper 312 is connected by the spring 314, it will not touch the surface of the filter grille 211. After the grid scraper 312 finishes scraping, it will move upward to reset. During this process, due to the special setting of the grid scraper 312, when moving upward, the side with the spring 314 fixed on the outer surface of the grid scraper 312 will be subject to a large wind resistance, causing the grid scraper 312 to rotate at the rotational connection with the scraper 311, so that the rubber contacts 313 contact the outside of the filter grille 211. When the rubber contacts 313 contact the grid of the filter grille 211, and the scraper 311 drives the grid scraper 312 to move upward, the dust in the grid of the filter grille 211 will be driven upward by the rubber contacts 313, thus avoiding the problem that dust accumulates in the grid and is difficult to remove, resulting in poor ventilation effect and affecting heat dissipation.

[0062] The circulating air component 32 includes a partition net 321 fixedly connected to the inner wall of the cooling tower shell 111. A fan 322 is arranged at the top of the cooling tower shell 111. A number of brushes 323 are fixedly connected to the outer wall of the partition net 321. Using the force of the rotation of the fan 322, a sedimentation chamber 122 is provided in the cooling tower to sediment dust and sundries entering the water flow. However, to avoid excessive dust, a filtration system is provided. When the air flow passes through the filtration system, since a spraying system 121 is provided inside the cooling tower, water vapor will be generated. A small amount of dust will adhere to the fan 322 due to the water vapor under the drive of the air flow. When the fan 322 rotates, it will pass by the brushes 323. Through the continuous rotation of the fan 322, the brushes 323 will continuously touch the fan, so that the dust cannot adhere to the fan 322, avoiding a large amount of dust adhering to the fan 322 due to water vapor and affecting the ventilation effect of the fan 322. Using the force of the contact between the brushes 323 and the fan 322, when a small amount of dust is knocked off by the fan 322, because the contact between the brushes 323 and the fan 322 will sweep off the dust originally adhering to the fan 322. When the swept-off dust falls downward, since the fan is always in a working state, it will continuously extract the air inside the equipment and flow it outwards, so that the originally swept-off dust will follow the air flow and be discharged outwards, avoiding the swept-off dust falling into the sedimentation chamber 122 and increasing the burden on the sedimentation chamber 122.

[0063] A specific application of this embodiment is as follows: Before use, install the filtering mechanism 2 and the circulation mechanism 3 in the condensation tower of the central air-conditioning ventilation system, so that the air flow passes through this device when the condensation tower works. Connect the power supply of this device and the condenser, and start the device. After starting the device, the air flow will enter the device through the filtering mechanism 2 on both sides of the main body mechanism 1, and the heat in the device will be taken away by the circulating air component 32. When the air flow passes through the inside of the device, the air grille 112 and the filtering grille 211 will block most foreign objects, such as leaves and dust. After the filtering grille 211 is used for a long time, start the motor 212 to make the rotating shaft 214 rotate, so that the large bevel gear 222 meshed with the bevel gear 221 rotates. A threaded rod 223 is fixedly connected to the lower end of the large bevel gear 222. When the threaded rod 223 rotates, the slider 224 meshed with the threaded rod 223 will be restricted from spinning between the filtering grille 211 and the air grille 112, and thus will be controlled by the thread rotated when the threaded rod 223 rotates, so that the fixedly connected cleaning component 31 moves downward. When the scraper 311 fixed on the outer wall of the slider 224 moves downward, the scraper 311 will scrape the caked dust on the surface of the filtering grille 211, thus restoring the air ventilation and filtering function of the filtering grille 211, and avoiding the problem of low cooling efficiency of the central air conditioner caused by the blockage of the filtering system.

[0064] Utilize the force of the up and down movement of the above-mentioned scraper 311. When the scraper 311 scrapes, since the grid scraper 312 is connected by the spring 314, it will not touch the surface of the filtering grille 211. After the grid scraper 312 finishes scraping, it will move upward and reset. During this process, due to the special setting of the grid scraper 312, when moving upward, the side of the outer surface of the grid scraper 312 fixed with the spring 314 will be subject to a large wind resistance, causing the rotating connection between the grid scraper 312 and the scraper 311 to rotate, so that the rubber contact 313 contacts the outside of the filtering grille 211. When the rubber contact 313 contacts the grid of the filtering grille 211, and the scraper 311 drives the grid scraper 312 to move upward, the dust in the grid of the filtering grille 211 will be driven upward by the rubber contact 313, thus avoiding the problem that the dust accumulates in the grid and is difficult to remove, resulting in poor ventilation and affecting heat dissipation. At the same time, the rubber contact 313 clears from bottom to top, which will drive the dust to move upward. A small amount of dust will adhere to the upper wall of the grid of the filtering grille 211, but due to gravity, it will not adhere to the outer wall for a long time, avoiding the problem that the dust becomes compact and difficult to clean during the cleaning process.

[0065] Using the force generated by the rotation of the fan 322, a sedimentation chamber 122 is provided in the condensing tower to sediment the dust and debris entering the water flow. However, to avoid excessive dust, a filtration system is provided. When the air flow passes through the filtration system, water vapor is generated due to the spray system 121 provided inside the condensing tower. A small amount of dust will adhere to the fan 322 due to the water vapor under the drive of the air flow. When the fan 322 rotates, it will pass by the brush 323. Through the continuous rotation of the fan 322, the brush 323 will continuously touch the fan, so that the dust cannot adhere to the fan 322, avoiding a large amount of dust adhering to the fan 322 due to the water vapor and affecting the ventilation effect of the fan 322.

[0066] Using the force of the contact between the brush 323 and the fan 322, when a small amount of dust is knocked off by the fan 322, the dust originally adhering to the fan 322 will be swept off due to the contact between the brush 323 and the fan 322. When the swept dust falls downward, since the fan is always in a working state, it will continuously extract the air inside the equipment and flow outward, causing the originally swept dust to be discharged outward along with the air flow, avoiding the swept dust from falling into the sedimentation chamber 122 and increasing the burden on the sedimentation chamber 122.
