[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the vertical push plate is pushed downward by the output rod of the electric cylinder. When the bottom of the vertical push plate contacts the top of the adjusting pressure plate, the adjusting pressure plate is pushed downward. The downward movement of the adjusting pressure plate drives the pull rod and the water injection piston to move downward together. The water injection piston compresses the air inside the water injection cylinder sleeve downward, causing the air pressure inside the water injection cylinder sleeve and the water storage tank to increase, and the soapy water inside the water storage tank is injected through the water guide sleeve and the water injection pipe, and sprinkled onto the pipeline welding position to perform welding air tightness detection. In addition, based on the observation of the position of the soap bubbles, the location of the leakage point can be more intuitively known.

[0020] 2. In the present invention, the vertical push plate is pushed downward by the output rod of the electric cylinder, and the vertical push plate drives the sliding column to move downward together. The downward movement of the sliding column drives the movable plate, the adjusting nut, the third return spring, the two metal springs, the two rubber water-stopping pads and the bubble net to move downward until the two metal springs are coated on the upper part of the outer wall of the pipe, and the rubber water-stopping pad is attached to the upper part of the outer wall of the pipe. Due to the coating effect of the two metal springs on the pipe, it is ensured that the soapy water infiltrated in the bubble net will not flow to both sides along the outer wall of the pipe, so that it is more concentrated in the inside of the bubble net, which is more convenient for observing the bubbles and also avoids unnecessary waste of soapy water.

[0021] 3. In the present invention, the vertical push plate is pushed downward by the output rod of the electric cylinder. After the bottom of the vertical push plate contacts the top of the cross bar, the cross bar is pushed downward together with the two push rods. The two push rods move downward to press down the two booster pistons, compressing the air inside the booster cylinder, and further boosting the inside of the pipeline through the booster hole, booster pipe, universal joint and telescopic pipe, resulting in an increase in the air pressure inside the pipeline. If there is a leak at the pipeline welding point, the air pressure inside the pipeline will cause the air to release pressure outward through the leak, thereby eliminating the need to install additional components such as an air pump, which is beneficial to controlling the production cost of the device.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 9 The technical solution provided by the present invention specifically includes the following embodiments:

[0034] Embodiment 1: A condenser pipeline airtightness detection device comprises an equipment frame 100, a positioning component 200 is provided on the top of the equipment frame 100, the positioning component 200 comprises two arc-shaped clamping plates 201 fixedly mounted on the front end and the rear end of the top of the equipment frame 100, three equally spaced weight bearing seats 202 are fixedly mounted on the inner walls of the two arc-shaped clamping plates 201, and the weight bearing seats 202 are all rotatably mounted with rollers 203 inside;

[0035] The positioning component 200 also includes two positioning frames 204 fixedly installed at the front and rear of the device frame 100, and a sliding sleeve 205 is fixedly installed on the top of the two positioning frames 204. The position of the sliding sleeve 205 corresponds to the position of the arc-shaped clamping plate 201, and a telescopic tube 206 is slidably installed inside the sliding sleeve 205. A sealing plug 207 is fixedly installed on the outer wall of the telescopic tube 206 close to the arc-shaped clamping plate 201. A tensioning spring 208 is provided on the periphery of the telescopic tube 206. The tensioning spring 208 is fixedly installed between the sliding sleeve 205 and the sealing plug 207. A handle 209 is fixedly installed on the outer wall of the end of the telescopic tube 206 away from the sealing plug 207.

[0036] Specifically, in this embodiment, the pipeline is supported by the supporting wheels 203, and the elastic action of the two front and rear tension springs 208 pushes the two sealing plugs 207 to abut against the two ends of the pipeline, thereby further sealing the two ends of the pipeline to form a sealed effect inside the pipeline.

[0037] Embodiment 2: A water injection component 300 is provided on the top of the equipment frame 100, and the water injection component 300 includes an electric cylinder 301. A crossbeam 101 is fixedly installed in the middle of the top of the equipment frame 100. The electric cylinder 301 is fixedly installed on the top of the crossbeam 101, and the output rod of the electric cylinder 301 movably extends to the bottom periphery of the crossbeam 101. A vertical push plate 302 is fixedly installed at the bottom of the output rod of the electric cylinder 301;

[0038] The water injection component 300 also includes a water storage tank 303 fixedly installed at the top right end of the equipment frame 100, a conducting port 3003 is opened at the top left end of the water storage tank 303, a water injection cylinder sleeve 304 is fixedly installed at the top of the opening of the conducting port 3003, a water injection piston 305 is slidably installed on the inner wall of the water injection cylinder sleeve 304, a pull rod 306 is penetrated at the bottom of the water storage tank 303, the outer wall of the pull rod 306 is slidably connected to the inner wall of the through hole at the bottom of the water storage tank 303, and the pull rod 306 and the water storage tank 303 are connected. A sealing ring is provided between the through holes, the top of the pull rod 306 is fixedly connected to the bottom of the water injection piston 305, a water guide sleeve 3014 is fixedly installed at the lower part of one side of the water storage tank 303 close to the electric cylinder 301, a water injection pipe 3015 is fixedly installed at the top of the water guide sleeve 3014, an adjusting pressure plate 3013 is fastened with bolts at the lower part of the outer wall of the pull rod 306, the water guide sleeve 3014 is connected to the inside of the water storage tank 303, and the inside of the water injection pipe 3015 is connected to the inside of the water guide sleeve 3014;

[0039] Specifically, the vertical push plate 302 is pushed downward by the output rod of the electric cylinder 301. When the bottom of the vertical push plate 302 contacts the top of the adjusting pressure plate 3013, the adjusting pressure plate 3013 is pushed downward. The downward movement of the adjusting pressure plate 3013 drives the pull rod 306 and the water injection piston 305 to move downward together. The water injection piston 305 compresses the air inside the water injection cylinder sleeve 304 downward, causing the air pressure inside the water injection cylinder sleeve 304 and the water storage tank 303 to increase, and the soapy water inside the water storage tank 303 is injected through the water guide sleeve 3014 and the water injection pipe 3015, and sprinkled onto the pipeline welding position to perform welding air tightness detection. In addition, based on the observation of the position of the soap bubbles, the location of the leakage point can be more intuitively known.

[0040] Furthermore, a second return spring 3010 is fixedly installed between the top wall of the water injection cylinder sleeve 304 and the top of the water injection piston 305; when the water injection piston 305 moves downward to compress the air inside the water injection cylinder sleeve 304, the second return spring 3010 is stretched and stored. Therefore, after the detection is completed, when the output rod of the electric cylinder 301 drives the vertical push plate 302 to move upward, the rebound force of the second return spring 3010 is released, so that the water injection piston 305 and the pull rod 306 are automatically reset upward, and an air intake hole 3011 is opened through the lower part of the side of the water storage tank 303 away from the electric cylinder 301. A one-way valve 3012 is fixedly installed on the periphery of the opening. When the water injection piston 305 is reset downward, the external air is sucked into the water tank 303 through the one-way conduction effect of the one-way valve 3012. When the water injection piston 305 compresses the air inside the water injection cylinder sleeve 304 downward, the air inside the water injection cylinder sleeve 304 will not overflow through the suction hole 3011 due to the irreversible conduction effect of the one-way valve 3012, thereby ensuring that the water injection cylinder sleeve 304 has sufficient pressure after the water injection piston 305 is compressed, ensuring that the soapy water inside the water tank 303 can be injected onto the pipe surface through the water injection pipe 3015 for an airtight test.

[0041] Embodiment 3: A water-stop component 400 is provided on the top of the equipment frame 100, and the water-stop component 400 includes a slide column 401 fixedly installed on the top of the vertical push plate 302, and the slide column 401 is located at the end of the top of the vertical push plate 302 away from the pull rod 306, and a movable plate 402 is slidably installed on the outer wall of the slide column 401, and two metal springs 404 distributed front and back are hinged on the top of the movable plate 402, and the outer walls of the metal springs 404 are sleeved with rubber water-stop pads 405, and a foaming net 406 is fixedly installed between the two rubber water-stop pads 405, and an adjusting nut 403 is screwed on the upper part of the outer wall of the slide column 401, and a third return spring 407 is provided on the periphery of the slide column 401, and the third return spring 407 is fixedly installed between the top of the movable plate 402 and the bottom of the adjusting nut 403;

[0042] Specifically, the vertical push plate 302 is pushed downward by the output rod of the electric cylinder 301, and the sliding column 401 is driven downward by the vertical push plate 302. The sliding column 401 moves downward, driving the movable plate 402, the adjusting nut 403, the third return spring 407, the two metal springs 404, the two rubber water-stopping pads 405 and the bubble net 406 to move downward until the two metal springs 404 are coated on the upper part of the outer wall of the pipe, and the rubber water-stopping pad 405 is attached to the upper part of the outer wall of the pipe. Due to the coating effect of the two metal springs 404 on the pipe, it is ensured that the soapy water infiltrated in the bubble net 406 will not flow to both sides along the outer wall of the pipe, so that it is more concentrated in the bubble net 406, which is more convenient for observing the bubbles and also avoids unnecessary waste of soapy water.

[0043] Embodiment 4: Two boosting cylinders 2010 distributed front and back are fixedly installed inside the equipment frame 100, and boosting pistons 2011 are slidably installed on the inner walls of the two boosting cylinders 2010, and push rods 2012 are fixedly installed on the tops of the two push rods 2011. A cross bar 2013 is fixedly installed on the tops of the two push rods 2012. A gap is provided between the top of the cross bar 2013 and the bottom of the vertical push plate 302. A boosting hole 2015 is opened at the lower part of the outer wall of the boosting cylinder 2010, and a boosting pipe 2016 is fixedly installed at the periphery of the opening of the boosting hole 215. A universal joint 217 is fixedly installed between the end of the boosting pipe 2016 away from the boosting hole 215 and the end of the telescopic tube 206;

[0044] Specifically, the output rod of the electric cylinder 301 pushes the vertical push plate 302 to move downward. After the bottom of the vertical push plate 302 contacts the top of the cross bar 2013, the cross bar 2013 is pushed downward together with the two push rods 2012. The two push rods 2012 move downward to press down the two booster pistons 2011, compressing the air inside the booster cylinder 2010, and further pressurizing the inside of the pipeline through the booster hole 2015, the booster pipe 2016, the universal joint 2017 and the telescopic pipe 206, resulting in an increase in the air pressure inside the pipeline. If there is a leak at the pipeline welding point, the air pressure inside the pipeline will cause the air to release pressure outward through the leak. At the same time, when the vertical push plate 302 is pushed downward, the air pressure inside the pipeline will increase. After the bottom of plate 302 contacts the top of adjusting pressure plate 3013, it pushes adjusting pressure plate 3013 to move downward. The downward movement of adjusting pressure plate 3013 drives pull rod 306 and water injection piston 305 to move downward together. Water injection piston 305 compresses the air inside water injection cylinder sleeve 304 downward, causing the air pressure inside water injection cylinder sleeve 304 and water storage tank 303 to increase, and the soapy water inside water storage tank 303 is injected through water guide sleeve 3014 and water injection pipe 3015. The soapy water injected by water injection pipe 3015 just pours on the inside of foaming net 406, thereby infiltrating foaming net 406. Afterwards, if soap bubbles appear on the surface of foaming net 406, it indicates that there is a leak at the pipe welding point.

[0045] Furthermore, a first return spring 2018 is provided inside the boost cylinder 2010, and the first return spring 2018 is fixedly installed between the bottom wall of the boost cylinder 2010 and the bottom of the boost piston 2011; when the push rod 2012 moves downward along the inner wall of the boost cylinder 2010, the first return spring 2018 is compressed and accumulates force, so that after the detection is completed, the output rod of the electric cylinder 301 drives the vertical push plate 302 to move upward, and the upward return effect of the boost piston 2011, the push rod 2012 and the cross bar 2013 can be automatically achieved through the rebound force of the first return spring 2018.

[0046] Furthermore, a collecting tank 500 is fixedly installed inside the equipment frame 100 through a bracket, and the collecting tank 500 is located at the bottom of the two metal spring sheets 404. A discharge pipe 501 is fixedly installed at the bottom of the collecting tank 500, and the interior of the discharge pipe 501 is connected to the interior of the collecting tank 500; the excess soapy water overflowing from the inside of the foaming net 406 is collected by the set collection tank 500, and the collected soapy water is discharged through the discharge pipe 501.

[0047] In the present scheme, a condenser pipeline airtightness testing device is operated. The welded condenser pipeline test sample is passed through two metal springs 404 and placed inside the front and rear arc-shaped clamping plates 201. The pipeline is supported by the supporting rollers 203. The two sealing plugs 207 are pushed to abut against the two ends of the pipeline through the elastic action of the front and rear tensioning springs 208, so as to further seal the two ends of the pipeline and form a sealed effect inside the pipeline.

[0048] Subsequently, the output rod of the electric cylinder 301 pushes the vertical push plate 302 to move downward, and the vertical push plate 302 drives the sliding column 401 to move downward together. The sliding column 401 moves downward to drive the movable plate 402, the adjusting nut 403, the third return spring 407, the two metal springs 404, the two rubber water-stopping pads 405 and the foaming net 406 to move downward until the two metal springs 404 are covered on the upper part of the outer wall of the pipe, and the rubber water-stopping pad 405 is attached to the upper part of the outer wall of the pipe. Subsequently, the output rod of the electric cylinder 301 continues to move downward, and is Under the reaction of the pipe to the metal spring sheet 404, the metal spring sheet 404 wrapped around the outer periphery of the pipe cannot continue to move downward, that is to say, the movable plate 402 stops moving downward, and the continued downward movement of the vertical push plate 302 will drive the sliding column 401 and the adjusting nut 403 to continue moving downward, resulting in the compression of the third return spring 407. It should be noted that when the metal spring sheet 404 just wraps around the outer wall of the pipe, the bottom of the vertical push plate 302 just contacts the top of the adjusting pressure plate 3013, and the bottom of the vertical push plate 302 just contacts the top of the cross bar 2013;

[0049] After the bottom of the vertical push plate 302 contacts the top of the cross bar 2013, the cross bar 2013 is pushed downward together with the two push rods 2012. The two push rods 2012 move downward to press down the two booster pistons 2011, compressing the air inside the booster cylinder 2010, and further pressurizing the inside of the pipeline through the booster hole 2015, the booster pipe 2016, the universal joint 2017 and the telescopic pipe 206, causing the air pressure inside the pipeline to increase. If there is a leak at the pipeline welding point, the air pressure inside the pipeline will cause the air to release pressure to the outside through the leak. At the same time, when the bottom of the vertical push plate 302 contacts the top of the adjusting pressure plate 3013, the adjusting pressure plate 3013 is pushed downward, and the downward movement of the adjusting pressure plate 3013 drives the pull rod 306 and the water injection piston 305 to move downward together. , the water injection piston 305 compresses the air inside the water injection cylinder sleeve 304 downward, causing the air pressure inside the water injection cylinder sleeve 304 and the water storage tank 303 to increase, and the soapy water inside the water storage tank 303 is injected through the water guide sleeve 3014 and the water injection pipe 3015. The soapy water injected by the water injection pipe 3015 just pours on the inside of the foaming net 406, thereby infiltrating the foaming net 406. Thereafter, if soap bubbles appear on the surface of the foaming net 406, it indicates that there is a leak at the welding point of the pipeline. During the detection process of the device, due to the coating effect of the two metal springs 404 on the pipeline, it is ensured that the soapy water infiltrated in the foaming net 406 will not flow to both sides along the outer wall of the pipeline, so that it is more concentrated in the foaming net 406, which is more convenient for observing bubbles and also avoids unnecessary waste of soapy water.

[0050] After inspecting one side of the pipeline, the output rod of the electric cylinder 301 moves upward to release the metal spring 404 from covering the pipeline, and the two pull rods 306 are moved in opposite directions to turn the other side of the pipeline upward and continue to inspect the other side of the pipeline, so that a comprehensive inspection effect can be provided at multiple pipeline welding positions.

[0051] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
