Description

Technical Field

[0001] This invention relates to the field of air conditioner sealing performance testing technology, specifically an air conditioner rain-testing sealing performance testing device. Background Technology

[0002] With the increasing prevalence of air conditioning, most minibuses, buses, and trains are now equipped with it. Since air conditioners are installed on the roof, and vehicles frequently encounter thunderstorms while in motion, after the air conditioners are manufactured, they need to undergo a rain test to simulate whether they leak water under external conditions.

[0003] Most common testing devices currently use vertical spraying at a fixed angle, which can only simulate static rainfall and cannot reproduce the dynamic working conditions of rainwater tilting and impacting when a vehicle is in motion. This leads to a deviation between the test results and the actual waterproof performance. In order to overcome the above technical problems, this invention provides an air conditioning rain sealing performance testing device that can simulate the working conditions of rainwater tilting and impacting when a vehicle is in motion. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide an air conditioning rain sealing performance testing device, which has the advantage of simulating the impact of rainwater on the air conditioner when a vehicle is driving in the rain.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides an air conditioner rain-testing sealing performance testing device, including a rain chamber, several spray units, and a movable frame set in the rain chamber by a movable component. The movable frame is provided with two L-shaped mounting plates, which are arranged opposite to each other. Each of the spray units is spaced apart on the two mounting plates along the length direction of the mounting plates. The movable component is used to drive the movable frame to move vertically up and down. Each of the spray units includes a horizontal spray pipe and two vertical spray pipes. The horizontal spray pipe is rotatably connected between two mounting plates, and the two vertical spray pipes are rotatably connected to the two mounting plates respectively. They are connected to the horizontal spray pipe through a first flexible hose, forming an inverted U-shaped pipeline. The horizontal and vertical spray pipes are equipped with multiple nozzles. The mounting plate is equipped with a driving mechanism, which is used to simultaneously drive the horizontal and vertical spray pipes in all spray units to rotate around their respective axes.

[0006] By adopting the above technical solution, the air conditioner is placed in the rain shower room. The drive mechanism works simultaneously to drive the horizontal and vertical spray pipes in all spray units to rotate around their respective axes, thereby changing the tilt angle of all nozzles. This allows the sprayed water curtain to change from vertical downward to tilted impact on the air conditioner under test below, simulating the rain shower state of the air conditioner when the vehicle is in motion, which greatly improves the authenticity and effectiveness of the test.

[0007] Preferably, a circulating filtration mechanism is provided on the ground on one side of the shower room. The circulating filtration mechanism is connected to each spray unit and is used to filter and collect the used water in the shower room.

[0008] Preferably, the driving mechanism includes two side plates mounted on one of the mounting plates, and a rotating shaft is rotatably connected between the two side plates. Multiple worm gear segments are provided axially on the rotating shaft, the number of worm gear segments being the same as the number of spray units. A first worm wheel and a first bevel gear are coaxially mounted on the horizontal spray pipe of each spray unit. A second worm wheel is coaxially mounted on one of the vertical spray pipes of each spray unit. Both the first and second worm wheels mesh with the corresponding worm gear segments. A servo motor for driving the rotating shaft is provided on one of the side plates. A second bevel gear is coaxially mounted on the other vertical spray pipe of each spray unit, and the second bevel gear corresponds to and meshes with the first bevel gear.

[0009] Preferably, the circulating filtration mechanism includes a ground trough, a collection pool, a filter pool, and a circulation pool. The ground trough is located on the ground inside the shower room. The collection pool, filter pool, and circulation pool are arranged side by side on the ground outside the shower room, and the collection pool is connected to the ground trough via a water guide channel. The filter pool is located on one side of the collection pool, and the lower side of one side of the collection pool is connected to the filter pool via a connecting channel. The circulation pool is located on the side of the filter pool away from the collection pool, and the circulation pool is connected to the filter pool. The filter pool and the collection pool are equipped with filter components for filtering water. The circulation pool is equipped with a water pumping component, which is connected to each spray unit and pumps water from the circulation pool into each spray unit.

[0010] Preferably, the filtration assembly includes a filter plate disposed in the collection tank, and the filter plate is located below the water guide channel. The filtration tank is divided into a first filtration zone, a second filtration zone, and a third filtration zone that are connected in sequence by partitions and baffles. Filter cotton is placed in the first filtration zone, activated carbon is placed in the second filtration zone, and porous filter media is placed in the third filtration zone. Water enters the first filtration zone through the connecting channel, overflows into the second filtration zone, flows through the bottom into the third filtration zone, and finally overflows into the circulation tank. There are two baffles and one partition, and the partition is located between the two baffles. The bottom end of the partition has a gap with the bottom of the filtration tank.

[0011] Preferably, the filter tank is provided with a drainage mechanism for draining the water that has been standing in the filter tank into the circulation tank when the machine is stopped.

[0012] Preferably, the drainage mechanism includes a connecting component that is disposed on both baffles. The connecting component includes a side groove disposed below one side of the baffle and a placement groove disposed on the top wall of the side groove. A closing plate is vertically slidably connected in the placement groove, and the bottom end of the closing plate extends into the side groove and closes the side groove. The baffle is provided with a pushing mechanism for driving the closing plate to move vertically. A placement rack located in the first filtration zone is placed in the filter pool. The filter cotton is located on the placement rack, and the middle part of one side of the filter cotton corresponds to the connecting groove.

[0013] Preferably, the pushing mechanism includes two suspension plates, which are respectively located above two baffles. A column is rotatably connected to the top of the closed plate, and the top of the column passes through the baffle and the suspension plate and is provided with a locking plate located above the suspension plate. The top of the suspension plate is provided with a vertical plate that cooperates with the locking plate.

[0014] Preferably, the water pumping assembly includes a water pumping pipe, a water distribution pipe, and a water pump installed on the water pumping pipe. The water pump is installed on one side wall of the circulating pool. The water distribution pipe is horizontally installed on the movable frame and is connected to the horizontal spray pipes in each of the spray units through several second flexible hoses. The end of the water pumping pipe away from the circulating pool passes through the rain shower room and is connected to the water distribution pipe through a third flexible hose.

[0015] Preferably, the trench opening is provided with a grid mesh for covering the trench opening, and the openings of the collection pool, filtration pool and circulation pool are all covered with cover plates. The three cover plates respectively close the openings of the collection pool, filtration pool and circulation pool. At this time, the column and the upright plate are located between two adjacent cover plates, and the top of the suspended plate is in contact with the bottom of the cover plate.

[0016] The beneficial effects of this invention are as follows: Dynamic simulation, realistic testing: By driving the inverted U-shaped spray pipe to rotate synchronously, the spray angle can be adjusted from vertical to tilted to simulate the rain conditions of a vehicle in motion, making the test results more reliable.

[0017] Synchronous drive, high efficiency and stability: It adopts a linkage design of one rotating shaft with multiple worm gear segments and bevel gears. Only one servo motor can synchronously drive multiple spray pipes of all spray units, with precise transmission, consistent action and compact structure.

[0018] Water-saving and environmentally friendly, easy to maintain: It integrates a high-efficiency multi-stage circulating filtration system (filter plate, filter cotton, activated carbon, porous filter media) to realize the recycling of water resources. The shutdown drainage mechanism can empty the water in the filter tank to prevent the filter cotton, activated carbon and porous filter media from being soaked in the water for a long time, which would affect the subsequent filtration of the filter cotton, activated carbon and porous filter media.

[0019] Highly adaptable and easy to operate: The mobile frame can be raised and lowered to accommodate air conditioners at different heights. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] An air conditioner rain-testing sealing performance testing device, such as Figure 1 and Figure 2 and Figure 3 It includes a shower room 1, several spray units 2 and a movable frame 3 set in the shower room by a movable component. The movable frame 3 is provided with two L-shaped mounting plates 31, and the two mounting plates 31 are arranged opposite each other. Each spray unit 2 is arranged at intervals on the two mounting plates 31 along the length direction of the mounting plates 31. The movable component is used to drive the movable frame 3 to move vertically up and down. Each spray unit 2 includes a horizontal spray pipe 21 and two vertical spray pipes 22. The horizontal spray pipe 21 is rotatably connected between two mounting plates 31, and the two vertical spray pipes 22 are rotatably connected to the two mounting plates 31 respectively. They are connected to the horizontal spray pipe 21 through a first flexible hose 23, forming an inverted U-shaped pipeline. Multiple nozzles 24 are provided on the horizontal spray pipe 21 and the vertical spray pipe 22. The mounting plate 31 is equipped with a drive mechanism, which is used to simultaneously drive the horizontal spray pipes 21 and vertical spray pipes 22 in all spray units 2 to rotate around their respective axes.

[0025] like Figure 1 and Figure 2 and Figure 3 The air conditioner is placed in the rain shower chamber 1. The drive mechanism works simultaneously to drive the horizontal spray pipes 21 and vertical spray pipes 22 in all spray units 2 to rotate around their respective axes, thereby changing the tilt angle of all nozzles 24. This allows the sprayed water curtain to change from vertical downward to tilted impact on the air conditioner under test below, simulating the rain shower state of the air conditioner when the vehicle is in motion, greatly improving the authenticity and effectiveness of the test. The moving frame 3 can be raised and lowered by the moving parts to adapt to air conditioners of different heights.

[0026] like Figure 1 and Figure 3 The moving part includes a lifting actuator, such as an electric cylinder 11, a hydraulic cylinder, or a lead screw slide. When the moving part is an electric cylinder 11, the electric cylinder 11 is installed on the shower room 1. One end of the piston rod of the electric cylinder 11 is connected to the top of the moving frame 3. When the electric cylinder 11 is turned on, the piston rod of the electric cylinder 11 can push the moving frame 3 to move up and down to adapt to air conditioners at different heights.

[0027] like Figure 1 and Figure 2 A circulating filtration mechanism is installed on the ground on one side of the rain shower room 1. The circulating filtration mechanism is connected to each spray unit 2 and is used to filter and collect the used water in the rain shower room 1. By filtering and collecting the used water in the rain shower room 1 through the circulating filtration mechanism, the waste of water resources can be reduced, thereby reducing the cost of air conditioning rain shower sealing performance testing.

[0028] like Figure 3 and Figure 4 and Figure 5 and Figure 6 The drive mechanism includes two side plates 311 mounted on one of the mounting plates 31, and a rotating shaft 312 is rotatably connected between the two side plates 311. The rotating shaft 312 is provided with a plurality of worm segments 3121 along the axial direction. The number of worm segments 3121 is the same as the number of spray units 2. A first worm wheel 211 and a first bevel gear 212 are coaxially provided on the horizontal spray pipe 21 of each spray unit 2. A second worm wheel 221 is coaxially provided on one of the vertical spray pipes 22 of each spray unit 2. The first worm wheel 211 and the second worm wheel 221 are both meshed with the worm segments 3121 at the corresponding positions. A servo motor 313 for driving the rotating shaft 312 is provided on one of the side plates 311. A second bevel gear 222 is coaxially provided on the other vertical spray pipe 22 in each spray unit 2, and the second bevel gear 222 corresponds to and meshes with the first bevel gear 212.

[0029] like Figure 3 and Figure 4 and Figure 5 and Figure 6 When the spray angle needs to be adjusted, the servo motor 313 starts, driving the rotating shaft 312 and its multiple worm gear segments 3121 to rotate synchronously. Each worm gear segment 3121 simultaneously drives the first worm wheel 211 and the second worm wheel 221 meshed with it to rotate, thereby driving the horizontal spray pipe 21 and one of the vertical spray pipes 22 to rotate around their respective axes. At the same time, the rotation of the horizontal spray pipe 21 drives the first bevel gear 212 fixed to it on the same axis to rotate. The first bevel gear 212 transmits power to the other vertical spray pipe 22 through meshing with the second bevel gear 222, causing it to rotate in the opposite direction around its own axis. Thus, all the horizontal spray pipes 21 and the two vertical spray pipes 22 in the spray unit 2 achieve synchronous and coordinated rotation under the drive of a single motor, so that the entire inverted U-shaped spray pipeline deflects as a unified whole, thereby simultaneously adjusting the spray direction of all the nozzles 24 and realizing a continuous and stable switch from vertical to inclined spray.

[0030] like Figure 1 and Figure 2 and Figure 8 and Figure 9 The circulating filtration mechanism includes a ground trough 12, a collection tank 4, a filter tank 5, and a circulating tank 6. The ground trough 12 is located on the ground inside the shower room 1. The collection tank 4, filter tank 5, and circulating tank 6 are arranged side by side on the ground outside the shower room 1, and the collection tank 4 is connected to the ground trough 12 via a water guide channel 13. The filter tank 5 is located on one side of the collection tank 4, and the lower side of one side of the collection tank 4 is connected to the filter tank 5 via a connecting channel 41. The circulating tank 6 is located on the side of the filter tank 5 away from the collection tank 4, and the circulating tank 6 is connected to the filter tank 5. Filter components for filtering water are provided in the filter tank 5 and the collection tank 4. A water pumping component is provided on the circulating tank 6, and the water pumping component is connected to each spray unit 2 and pumps the water in the circulating tank 6 into each spray unit 2. The filter component includes components installed in the collection tank 12, the collection tank 4, the filter tank 5, and the circulating tank 6. The filter plate 42 in the collection tank 4 is located below the water guide channel 13. The filter tank 5 is divided into a first filter zone 53, a second filter zone 54 and a third filter zone 55 by partitions 51 and baffles 52. The first filter zone 53 contains filter cotton 531, the second filter zone 54 contains activated carbon 541, and the third filter zone 55 contains porous filter media 551 (such as a bacterial house). Water enters the first filter zone 53 through the connecting channel 41, overflows into the second filter zone 54, flows through the bottom into the third filter zone 55, and finally overflows into the circulation tank 6. There are two baffles 52 and one partition 51, with the partition 51 located between the two baffles 52. The bottom of the partition 51 has a gap with the bottom of the filter tank 5.

[0031] like Figure 1 and Figure 2 and Figure 8 and Figure 9 The wastewater after the spray test is collected by the ground trough 12 on the ground of the rain shower room 1 and introduced into the collection tank 4 through the water guide trough 13. The wastewater first flows through the filter plate 42 in the collection tank 4 to intercept large solid impurities and complete the preliminary filtration. There can be several filter plates 42, and each filter plate 42 is arranged at intervals from bottom to top. The filter holes on each filter plate 42 gradually decrease from top to bottom. After initial filtration, the water enters the first filtration zone 53 of the filtration tank 5 through the connecting channel 41 below the side wall of the collection tank 4. The filter cotton 531 placed in the first filtration zone 53 further filters the water. Then, as the water level rises, the water flows over the top of the baffle 52 between the first filtration zone 53 and the second filtration zone 54. At this time, the filter cotton 531 is submerged in the water, and the water flows into the second filtration zone 54 in an overflow manner. The activated carbon 541 filled in the second filtration zone 54 effectively adsorbs dissolved organic matter, odors and some chemical substances in the water. Subsequently, the water flows from the bottom of the second filtration zone 54, through the gap between the baffle 51 and the bottom of the filtration tank 5, and enters the third filtration zone 55. The porous filter media 551 in the third filtration zone 55 decomposes trace organic matter in the water through biodegradation, achieving deep purification. After completing the three-stage purification process, the clean water overflows into the circulation tank 6 for storage. The pumping components on the circulation tank 6 pump the purified water back into each spray unit 2 for testing and recycling. This process realizes a complete closed-loop cycle of test wastewater collection → preliminary filtration → multi-stage deep purification → storage and reuse, which significantly saves water resources and ensures the stability of water quality during testing.

[0032] like Figure 7 and Figure 8 and Figure 9The filter tank 5 is equipped with a drainage mechanism for draining the stagnant water in the filter tank 5 into the circulation tank 6 when the machine is stopped. The drainage mechanism includes a connecting component that is mounted on two baffles 52. The connecting component includes a side groove 521 located below one side of the baffle 52 and a placement groove 5211 located on the top wall of the side groove 521. A closing plate 5212 is vertically slidably connected in the placement groove 5211, and the bottom end of the closing plate 5212 extends into the side groove 521 and closes the side groove 521. The baffle 52 is equipped with a pusher for driving the closing plate 5212 to move vertically. The mechanism includes a placement rack 532 located in the first filtration zone 53 in the filtration tank 5, a filter cotton 531 located on the placement rack 532, and the middle of one side of the filter cotton 531 corresponding to the connecting groove 41. The pushing mechanism includes two suspension plates 56, which are respectively located above two baffles 52. The top of the sealing plate 5212 is rotatably connected to a column 5213. The top of the column 5213 passes through the baffles 52 and the suspension plates 56 and is provided with a clamping plate 5214 located above the suspension plates 56. The top of the suspension plate 56 is provided with a vertical plate 561 that cooperates with the clamping plate 5214.

[0033] like Figure 7 and Figure 8 and Figure 9 During normal testing and filtration, the sealing plate 5212 closes the side groove 521. When the test is over and long-term shutdown is required, the operator pulls the clamping plate 5214 upward. At this time, the clamping plate 5214 will drive the sealing plate 5212 upward through the column 5213, thereby opening the side groove 521. When the clamping plate 5214 moves to the top of one side of the vertical plate 561, the clamping plate 5214 is rotated so that one end is locked on the top of the vertical plate 561, thereby locking the sealing plate 5212 in the open position. At this time, the stagnant water retained in the first, second and third filtration zones 55 in the filter tank 5 can be discharged into the circulation tank 6 through the side groove 521 that has been opened on the two baffles 52 under the action of gravity. During this process, the water discharged into the circulation tank 6 also passes through the filter cotton 531, activated carbon 541 and porous filter media 551 in sequence before being discharged into the circulation tank 6. This drainage mechanism enables the emptying of stagnant water in each chamber of the filter tank 5 when the system is shut down. This effectively prevents stagnant water from remaining in the filter tank 5 for a long time, soaking various filter media and causing microorganisms (mold, bacteria) to grow on the filter media. This ensures the hygiene and efficiency of the filtration system during long-term operation. Filter cotton 531 is composed of several filter cotton plates arranged at intervals from top to bottom (e.g.) Figure 10When the filter cotton 531 becomes clogged and the water flow is obstructed during the test, the drainage mechanism adjacent to the filter cotton 531 can be opened to lift the sealing plate 5212 and open the side channel 521. At this time, the water flowing through the upper part of the filter cotton 531 plate continues to overflow over the top of the baffle 52 and enter the second filtration zone 54, while the water flowing under the filter cotton 531 plate can directly flow into the second filtration zone 54 through the open side channel 521. This dual flow path can effectively alleviate the problem of rapid rise in the water level of the collection tank 4 caused by temporary blockage of the filter cotton 531 without stopping the machine, ensuring the continuity of the test process and the stability of the system operation.

[0034] like Figure 2 and Figure 4 and Figure 8 The water pumping assembly includes a pumping pipe 62, a distribution pipe 32, and a pumping pump 61 mounted on the pumping pipe 62. The pumping pump 61 is mounted on one side wall of the circulating pool 6. The distribution pipe 32 is horizontally mounted on the movable frame 3 and is connected to the horizontal spray pipes 21 in each spray unit 2 via several second hoses 321. The end of the pumping pipe 62 away from the circulating pool 6 passes through the rain shower room 1 and is connected to the distribution pipe 32 via a third hose 621. By starting the pumping pump 61, the water stored in the circulating pool 6 is pumped out. The water flows sequentially through the pumping pipe 62 and the third hose 621 into the distribution pipe 32. The distribution pipe 32 serves as the main water distribution pipe, distributing water to all spray units 2 via several second hoses 321, providing a stable and reliable water supply for the rain shower test.

[0035] like Figure 1 and Figure 2 and Figure 7 The trench 12 is provided with a grid 121 to cover the opening of the trench 12. The openings of the collection pool 4, the filter pool 5 and the circulation pool 6 are all covered with cover plates 7. The three cover plates 7 respectively close the openings of the collection pool 4, the filter pool 5 and the circulation pool 6. At this time, the column 5213 and the upright plate 561 are located between two adjacent cover plates 7, and the top of the suspension plate 56 is in contact with the bottom of the cover plate 7. The cover plates 7 can reduce the amount of external impurities falling from the openings of the collection pool 4, the filter pool 5 and the circulation pool 6 into the collection pool 4, the filter pool 5 and the circulation pool 6.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
