Description

Technical Field

[0001] The present invention relates to the technical field of condenser detection, and in particular to a leakage detection device for a refrigeration and air-conditioning condenser. Background Art

[0002] Air conditioning, also known as air conditioner, is a small air conditioner composed of four parts: a refrigeration (heat) circulation system, an air circulation and ventilation system, an electrical control system, and a cabinet. It keeps the air in the conditioned space at a certain temperature, humidity, flow rate, cleanliness, and freshness.

[0003] Air conditioners require refrigerant during the cooling process. The heat exchanger that compresses the refrigerant and releases heat externally is called a condenser. The condenser is usually placed externally. Whether it is a car air conditioner or a household air conditioner, the condenser is a heat exchanger used to release heat during cooling.

[0004] Because the air conditioner works for a long time or is subjected to external impact and vibration, the refrigerant inside the condenser is continuously compressed, thereby generating high pressure. Leaks may occur at the connection points between the condenser and the external pipeline or at the welding points of the condenser, resulting in reduced cooling effect or even failure. When detecting condenser leaks, a refrigerant leak detector is usually required.

[0005] The existing detection device uses a roller to clean the surface of the detection pipe during detection. However, the roller cleaning process cannot clean the position of the pipe surface directly opposite the detection device, so that dust will still enter the detection device when it inhales air. At the same time, the overall cleaning structure is on the outside of the detection device. Since the internal pipelines of the air conditioner are relatively complicated, the detection device will hook part of the pipeline when it is inserted or removed, thereby affecting the insertion or removal of the detection.

[0032] The pressing and resetting assembly 208 includes a slide rod 208a, and a slide groove 208b is opened on the left side of the mounting frame 205. The right end of the slide rod 208a passes through the interior of the slide groove 208b and is movably connected to the slide groove 208b. The surface of the slide rod 208a is provided with a second spring 208c, and the left end of the second spring 208c is fixedly connected to the right side of the cleaning plate 206, and the right end of the second spring 208c is fixedly connected to the left side of the mounting frame 205.

[0033] The reset and opening assembly 209 includes a telescopic rod 209a, which is fixedly connected to the outside of the mounting bracket 205. A third spring 209b is sleeved on the surface of the telescopic rod 209a. The inner end of the third spring 209b is fixedly connected to the mounting bracket 205, and the outer end of the third spring 209b is fixedly connected to the inner wall of the rotating cylinder 202.

[0034] The limiting assembly 210 includes a limiting groove 210a, which is opened on the inner wall of the limiting cylinder 204. There are several limiting grooves 210a and they are distributed in a circular shape with equal distances. The left side of the limiting groove 210a is movably connected to the limiting block 210b, and the inner side of the limiting block 210b is fixedly connected to the right side of the surface of the fixed cylinder 201.

[0035] The air suction cleaning component 211 includes a first solenoid valve 211a, and connecting pipes 211b are provided on the front and rear sides of the surface of the installation cylinder 101. The front and rear sides of the left side of the surface of the installation cylinder 101 are fixedly connected with a second solenoid valve 211c. The first solenoid valve 211a and the second solenoid valve 211c are both connected to the connecting pipe 211b. A filter cylinder 211d is fixedly installed on the right side of the connecting pipe 211b, and the right side of the filter cylinder 211d is connected to the external air pump.

[0036] The control switching assembly 212 includes a mounting groove 212a, and a contact switch 212b is fixedly installed inside the mounting groove 212a. The contact switch 212b is electrically connected to the first solenoid valve 211a and the second solenoid valve 211c through a wire. A push ring 212c is movably connected to the left side of the surface of the mounting cylinder 101. The push ring 212c is movably connected to the rotating cylinder 202. The push ring 212c is movably connected to the contact switch 212b. The right side of the push ring 212c is fixedly connected to the fourth spring 212d, and the right end of the fourth spring 212d is fixedly connected to the fixed cylinder 201.

[0037] Specifically, when the rotating cylinder 202 moves to the left inside the fixed cylinder 201, the thread groove 203a and the thread teeth 203b can cause the rotating cylinder 202 to rotate, so that the rotating cylinder 202 rotates during the process of moving to the left, so that the rotating cylinder 202 can drive the mounting frame 205 to rotate through the telescopic rod 209a, so that the mounting frame 205 can drive the cleaning plate 206 to rotate through the slide rod 208a inside the slide groove 208b, so that the cleaning plate 206 can drive the cleaning bristles 207 to rotate, so that the cleaning bristles 207 can clean the surface of the pipe after rotation, and at the same time, when the rotating cylinder 202 moves to the left, the first spring 203c can drive the rotating cylinder 202 to move to the right for reset through its own elastic force.

[0038] When the rotating drum 202 moves, the mounting bracket 205 can be driven to move by the telescopic rod 209a, so that after the mounting bracket 205 moves, the cleaning plate 206 can be moved to the left by the elastic force of the second spring 208c itself, so that the cleaning plate 206 can move to the left while driving the cleaning bristles 207 to move to the left, so that the cleaning bristles 207 fit the surface of the pipe, increasing the cleaning effect of the cleaning bristles 207 on the pipe, and at the same time, the coordinated use of the sliding rod 208a and the sliding groove 208b can prevent the cleaning plate 206 from detaching from the mounting bracket 205.

[0039] At the same time, the use of the telescopic rod 209a can ensure that the mounting frame 205 moves back and forth inside the mounting cylinder 101. At the same time, the use of the telescopic rod 209a can ensure that the rotating cylinder 202 drives the mounting frame 205 to rotate when rotating, and the third spring 209b on the surface of the telescopic rod 209a can drive the mounting frame 205 to fit together through its own elastic force, thereby ensuring that the cleaning plates 206 fit together, avoiding gaps between the cleaning plates 206 and the cleaning plates 206 when cleaning the pipe surface.

[0040] The limiting cylinder 204 can limit the fixing cylinder 201 through the limiting block 210b inside the limiting groove 210a, thereby preventing the fixing cylinder 201 from rotating when the installation cylinder 101 moves to the left, thereby ensuring the stability of the fixing cylinder 201 during use.

[0041] Before the cleaning hairs 207 on the cleaning plate 206 clean the surface of the pipeline, the filter cartridge 211d is first connected to the external vacuum pump. When the cleaning hairs 207 on the cleaning plate 206 clean the pipeline, the external vacuum pump is started, so that the dust cleaned by the cleaning hairs 207 enters the interior of the connecting pipe 211b through the first solenoid valve 211a, so that the filter cartridge 211d can filter and collect the dust. When the first solenoid valve 211a is opened, the second solenoid valve 211c is closed. When the second solenoid valve 211c is opened, the first solenoid valve 211a is closed. After the second solenoid valve 211c is opened, the air pump will actively and quickly suck the air near the pipeline to the vicinity of the probe 102, so that the probe 102 can quickly inhale and detect the leaked gas.

[0042] When the mounting cylinder 101 is continuously pushed to the left, the rotating cylinder 202 rotates and the pushing ring 212c is subjected to the reaction force to move to the right on the surface of the mounting cylinder 101 and compress the fourth spring 212d. When the mounting cylinder 101 moves to the right, it contacts the contact switch 212b inside the mounting groove 212a, so that the contact switch 212b can close the first solenoid valve 211a and open the second solenoid valve 211c. At the same time, after the pushing ring 212c is separated from the contact switch 212b, the contact switch 212b can control the first solenoid valve 211a to open and the second solenoid valve 211c to close.

[0043] Furthermore, when it is necessary to detect the leakage of the pipeline, the installation cylinder 101 is placed so that the fixed cylinder 201 on the left side is fitted with the leaking pipeline, and then the installation cylinder 101 is pushed. When the installation cylinder 101 moves to the left, it will drive the limiting cylinder 204 to move to the left on the surface of the fixed cylinder 201, and the limiting groove 210a inside the limiting cylinder 204 cooperates with the limiting block 210b to limit the fixed cylinder 201. At the same time, the fourth spring 212d can drive the pushing ring 212c to move to the left. As the pushing ring 212c moves to the left, it can drive the rotating cylinder 202 to move on the installation cylinder 101. The interior moves to the left, causing the rotating cylinder 202 to move to the left. At the same time, the rotating cylinder 202 itself can be rotated by cooperating with the thread groove 203a and the thread teeth 203b. As the rotating cylinder 202 rotates, the mounting bracket 205 can be driven to move and rotate through the telescopic rod 209a and compress the second spring 208c. After the mounting bracket 205 rotates, it can drive the sliding rod 208a inside the sliding groove 208b to drive the cleaning plate 206 to rotate. After the cleaning plate 206 rotates, it can drive the cleaning bristles 207 to rotate, so that the cleaning bristles 207 can clean the surface of the pipe after rotation.

[0044] Before cleaning, the filter cartridge 211d will be connected to the external vacuum pump so that the cleaning bristles 207 can clean the surface of the pipe. During cleaning, the external vacuum pump can push the air and dust inside the fixed cylinder 201 into the connecting pipe 211b through the first solenoid valve 211a, so that the filter cartridge 211d connected to the connecting pipe 211b can filter and collect the dust in the air.

[0045] After the rotating cylinder 202 rotates and moves to the left, the first spring 203 c is compressed. After the first spring 203 c is compressed to the compression stroke, the rotating cylinder 202 loses the stroke to move to the left and cannot rotate.

[0046] While the push ring 212c moves to the right, the push ring 212c can fit the contact switch 212b inside the mounting groove 212a and compress the fourth spring 212d after moving to the right on the surface of the mounting tube 101. When the contact switch 212b and the push ring 212c fit together, the first solenoid valve 211a can be closed and the second solenoid valve 211c can be opened, so that the external vacuum pump can draw the air in the pipeline into the interior of the mounting tube 101 and enter the connecting pipe 211b through the second solenoid valve 211c, so that the gas leaked in the pipeline can quickly enter the interior of the mounting tube 101, so that the probe 102 can quickly inhale and detect the leaked gas in the air.

[0047] It should be noted that the elastic force of the fourth spring 212d is greater than the elastic force of the first spring 203c.

[0048] Example 2 Reference Figures 1 to 4 , which is a second embodiment of the present invention, provides a partition opening mechanism 300, through which the partition plate 301 can be opened or closed.

[0049] The partition opening mechanism 300 includes a partition plate 301, which is arranged on the front and rear sides of the left side of the installation tube 101. The front and rear sides of the left side of the surface of the installation tube 101 are fixedly connected with torsion spring hinges 302. The partition plate 301 is movably connected to the installation tube 101 through the torsion spring hinge 302. The left side of the partition plate 301 is fixedly connected with an opening component 303, and the left side of the top and bottom of the installation tube 101 are fixedly connected with a separation component 304.

[0050] The opening assembly 303 includes a fixing frame 303a, a traction rope 303b is fixedly connected to the surface of the fixing frame 303a, and one end of the traction rope 303b away from the fixing frame 303a is fixedly connected to the surface of the push ring 212c.

[0051] The separation assembly 304 includes a fixed seat 304a, which is fixedly connected to the left side of the top and bottom of the fixed cylinder 201. A separation frame 304b is provided on the left side of the fixed cylinder 201. The right end of the separation frame 304b is fixedly connected to the left side of the fixed seat 304a. The separation frame 304b is movably connected to the mounting frame 205, and the mounting frame 205 is movably connected to the partition plate 301.

[0052] An interception ring A is fixedly connected to the left side of the inside of the installation cylinder 101. The interception ring A is movably connected to the cleaning hair 207. A rubber fitting ring B is fixedly connected to the left side of the installation cylinder 101.

[0053] Specifically, after the rotating cylinder 202 stops rotating, it continues to push the mounting cylinder 101, and the mounting cylinder 101 will drive the separation frame 304b to move to the left through the fixing seat 304a, so that the separation frame 304b can contact the mounting frame 205 after moving to the left. As the separation frame 304b continues to move to the left, it can push the mounting frame 205 outward.

[0054] After the rotating cylinder 202 stops rotating, the mounting cylinder 101 is continuously pushed and the pushing ring 212c will be subjected to the reaction force and move to the right, so that the pushing ring 212c can move to the right through the traction rope 303b when the surface of the mounting cylinder 101 moves to the right, so that after the traction rope 303b moves to the right, the partition plate 301 can be opened through the fixing frame 303a, so that the partition plate 301 is rotated by the torsion spring hinge 302. In the process of the partition plate 301 rotating and opening by the torsion spring hinge 302, it will contact the mounting frame 205 and further separate from the mounting frame 205 through the inclined surface of the mounting frame 205.

[0055] After the mounting frame 205 moves outward, the cleaning plate 206 can be driven to move outward through the sliding rod 208a inside the sliding groove 208b, so that after the cleaning plate 206 moves outward, the cleaning bristles 207 can be driven to move outward, and the intercepting ring A can store the cleaning bristles 207 to prevent the cleaning bristles 207 from contacting uncleaned positions on the pipe when moving outward.

[0056] At the same time, the use of the rubber fitting ring B can ensure that the fixing tube 201 does not cause damage to the pipeline surface after being fitted to the pipeline.

[0057] Furthermore, at this time, the installation cylinder 101 is continued to be pushed. During the movement of the installation cylinder 101, the separation frame 304b is driven to move to the left through the fixing seat 304a, so that the separation frame 304b can contact the installation frame 205, and the two installation frames 205 are separated by the inclined surface on the installation frame 205. As the installation cylinder 101 moves, the pushing ring 212c is unable to push the rotating cylinder 202 and thus moves to the right on the surface of the installation cylinder 101 through the reaction force, so that the pushing ring 212c can pull the traction rope 303b while the surface of the installation cylinder 101 moves to the right, so that the traction rope 303b Under the traction of the pushing ring 212c, the partition plate 301 can be opened through the fixed frame 303a, so that the partition plate 301 can be unfolded through the torsion spring hinge 302. After the partition plate 301 is opened, the probe 102 inside the mounting tube 101 can inhale and detect the gas in the air. As the partition plate 301 is unfolded, the mounting frame 205 can be further opened, so that the mounting frame 205 drives the cleaning plate 206 to move outward through the sliding rod 208a inside the sliding groove 208b, and the intercepting ring A inside the fixed tube 201 then moves the cleaning hair 207 outward to store the cleaning hair 207.

[0058] It should be noted that the traction rope 303b is not in a straight state in the initial state, and there is a moving traction amount.

[0059] The remaining structures are the same as those of Example 2.

[0060] Example 3 Reference Figures 1 to 5 , which is the third embodiment of the present invention, is different from the second embodiment in that: a detection device for refrigeration and air conditioning condenser leakage.

[0061] When it is necessary to detect the leakage of the pipeline, the installation cylinder 101 is used to fit the fixed cylinder 201 on the left side to the leaking pipeline, and then the installation cylinder 101 is pushed. When the installation cylinder 101 moves to the left, it will drive the limiting cylinder 204 to move to the left on the surface of the fixed cylinder 201, and the limiting groove 210a inside the limiting cylinder 204 cooperates with the limiting block 210b to limit the fixed cylinder 201. At the same time, the fourth spring 212d can drive the pushing ring 212c to move to the left. As the pushing ring 212c moves to the left, the rotating cylinder 202 can be driven to rotate inside the installation cylinder 101. The left side moves, so that the rotating cylinder 202 moves to the left side, and at the same time, the rotating cylinder 202 itself can be rotated by cooperating with the thread groove 203a and the thread teeth 203b. As the rotating cylinder 202 rotates, the mounting bracket 205 can be driven to move and rotate through the telescopic rod 209a and compress the second spring 208c, so that after the mounting bracket 205 rotates, the sliding rod 208a inside the sliding groove 208b can drive the cleaning plate 206 to rotate. After the cleaning plate 206 rotates, it can drive the cleaning bristles 207 to rotate, so that the cleaning bristles 207 can clean the surface of the pipe after rotation.

[0062] Before cleaning, the filter cartridge 211d will be connected to the external vacuum pump so that the cleaning bristles 207 can clean the surface of the pipe. During cleaning, the external vacuum pump can push the air and dust inside the fixed cylinder 201 into the connecting pipe 211b through the first solenoid valve 211a, so that the filter cartridge 211d connected to the connecting pipe 211b can filter and collect the dust in the air.

[0063] After the rotating cylinder 202 rotates and moves to the left, the first spring 203 c is compressed. After the first spring 203 c is compressed to the compression stroke, the rotating cylinder 202 loses the stroke to move to the left and cannot rotate.

[0064] At this time, continue to push the installation cylinder 101. During the movement of the installation cylinder 101, the separation frame 304b will be driven to move to the left through the fixing seat 304a, so that the separation frame 304b can contact the installation frame 205, and the two installation frames 205 are separated by the inclined surface on the installation frame 205. As the installation cylinder 101 moves, the pushing ring 212c will move to the right on the surface of the installation cylinder 101 through the reaction force because it cannot push the rotating cylinder 202. When the pushing ring 212c moves to the right on the surface of the installation cylinder 101, it can pull the traction rope 303b, so that the traction rope 303b is pushed The traction of the dynamic ring 212c can open the partition plate 301 through the fixed frame 303a, so that the partition plate 301 can be unfolded through the torsion spring hinge 302. After the partition plate 301 is opened, the probe 102 inside the mounting tube 101 can inhale and detect the gas in the air. As the partition plate 301 is unfolded, the mounting frame 205 can be further opened, so that the mounting frame 205 drives the cleaning plate 206 to move outward through the slide rod 208a inside the slide groove 208b, and the intercepting ring A inside the fixed tube 201 then moves the cleaning hair 207 outward to store the cleaning hair 207.

[0065] While the push ring 212c moves to the right, the push ring 212c can fit the contact switch 212b inside the mounting groove 212a and compress the fourth spring 212d after moving to the right on the surface of the mounting tube 101. When the contact switch 212b and the push ring 212c fit together, the first solenoid valve 211a can be closed and the second solenoid valve 211c can be opened, so that the external vacuum pump can draw the air in the pipeline into the interior of the mounting tube 101 and enter the connecting pipe 211b through the second solenoid valve 211c, so that the gas leaked in the pipeline can quickly enter the interior of the mounting tube 101, so that the probe 102 can quickly inhale and detect the leaked gas in the air.

[0066] After the probe 102 completes the gas leakage detection, the mounting cylinder 101 is taken out. At this time, the first spring 203c can drive the rotating cylinder 202 to reset inside the fixed cylinder 201 through its own elastic force. At the same time, the second spring 208c can drive the cleaning plate 206 to reset. The third spring 209b can drive the mounting frame 205 to reset. The fourth spring 212d can drive the pushing ring 212c to reset on the surface of the mounting cylinder 101 through its own elastic force.

[0067] In summary, the rotating cylinder 202 can cooperate with the rotating component 203 to drive the cleaning plate to rotate, and at the same time cooperate with the filter cylinder 211d to ensure that the cleaning hair 207 can collect and filter the dust in the air while cleaning the dust. At this time, continuously pushing the installation cylinder 101 can open the partition plate 301 through the opening component 303 and the separation component 304, so that the partition plate 301 is opened to release the partition of the probe 102, so that the probe 102 can detect the leaked gas.
