Description

Technical Field

[0001] The invention relates to the technical field of heat pump channel repair, in particular to a quick-repair composite leak detection device for heat pump pipelines. Background Art

[0002] As we all know, heat pump pipes are pipes used to transport heat transfer media in heat pump systems. Common types include polyethylene pipes, polybutylene pipes, aluminum-plastic composite pressure pipes, and copper pipes. When selecting, you need to consider the system type, operating temperature and pressure, corrosion resistance, and installation ease. Pay attention to pipe connections during installation, and maintenance is required during long-term use to avoid the risk of rupture.

[0003] The existing technology has the following problems: when inspecting and repairing existing heat pump pipes, the existing pipes have a larger radius and are usually longer than other pipes, so the efficiency of using conventional inspection and maintenance equipment is low. In addition, maintenance during inspection requires frequent switching of equipment, which is inconvenient. In addition, defects such as cracks found during inspection are easily removed or difficult to identify with the adhesive labels, which is inconvenient to use. Based on the above-mentioned situation, we found that it is difficult for the existing heat pump pipeline inspection and repair device to avoid the above problems at the same time. Therefore, we proposed an integrated detection and repair method, which can quickly detect the entire outside of the heat pump pipeline, reduce the detection blind spots, and quickly perform temporary repairs when cracks are found. While providing temporary protection, it can also facilitate identification so that personnel can carry out complete repairs in time. It is a quick-repair composite leak detection device for heat pump pipelines. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention provides a rapid repair composite leak detection device for heat pump pipelines, which has integrated detection and repair capabilities, can quickly detect the entire outer side of the heat pump pipeline, reduce detection blind spots, and can quickly perform temporary repairs when cracks are found. While providing temporary protection, it can also be easily identified so that personnel can promptly carry out complete repairs later.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A rapid repair composite leak detection device for heat pump pipelines, comprising two sets of support rings, the outer sides of the support rings being movably connected to guide frames, and the outer sides of the guide frames being movably connected to a repair mechanism; The repair mechanism includes a shell, a roll clamp is fixedly connected to the inner side of the shell, a tape roll is sleeved on the outer side of the roll clamp, a contact ring is fixedly connected to the front side of the shell, a side shell is fixedly connected to the bottom of the contact ring, a heat conducting plate is fixedly connected to the right side of the side shell, a heating shell is provided at the bottom of the side shell, and heating wires are provided on the inner sides of the heating shell and the side shell; The support ring includes a top ring and a bottom ring, the rear sides of the top ring and the bottom ring are fixedly connected to friction rings, the front sides of the top ring and the bottom ring are fixedly connected to detection probes, the inner sides of the top ring and the bottom ring are fixedly connected to rolling racks, the inner sides of the rolling racks are movably connected to balls, and the inner sides of the top ring on the right and the bottom ring on the right are fixedly connected to holding parts.

[0006] By adopting the above technical solution, the device can be directly installed on the outside of the heat pump pipeline by setting a support ring. When in use, the two sets of top rings and bottom rings can be relatively opened, and the top ring and bottom ring can be clamped on the outside of the heat pump pipeline. At this time, the rollers on the inner sides of the top ring and the bottom ring are in contact with the heat pump pipeline through the balls, and the circumferentially inclined detection probes can continuously detect damage, leakage and cracks on the surface of the heat pump pipeline. The two sets of support rings also play the role of installing the repair mechanism. When in use, the repair mechanism can be installed on the outside of the two sets of support rings through the guide frame. When a defect to be repaired is detected on the outside of the heat pump pipeline, the personnel can hold the holding part of the right support ring, and can pass The guide frame rotates circumferentially along the support ring. During the rotation, the tape part of the tape roll will stick to the outside of the pipe. As the guide frame rotates, the tape roll is continuously pulled and rotates along the roll clamp, and the tape is continuously pulled out. At this time, the heating wire on the inside of the side shell heats the tape, causing it to initially melt to provide further adhesion so that it can be firmly adhered to the outside of the pipe and not easily loosened. After winding a certain number of times until the repair area is covered, the guide frame is stopped and the heating wire on the inside of the heating shell melts the tape, and the melted tape will be attached to the outside of the heating shell for subsequent use. At this time, the entire repair structure can be lifted from the outside of the pipe so that it is no longer in contact, and subsequent maintenance work can be carried out.

[0007] The present invention is further configured as follows: a cover is clamped on the front side of the shell, and the tape roll is made of a silicone rubber tape material.

[0008] By adopting the above technical solution, by setting a cover, when the tape roll needs to be replaced, the cover can be opened to quickly install a new tape roll inside the shell. The tape roll made of silicone rubber tape material has good bonding strength, strength and sealing, which can prevent water leakage from the repaired leak.

[0009] The present invention is further configured as follows: the front side of the shell is rotatably connected to a limiting wheel, a plurality of hollow teeth are provided on the outer side of the limiting wheel, a metal sheet is fixedly connected to the right side of the heating shell, an extension frame is fixedly connected to the left side of the side shell, a connecting spring is fixedly connected to the bottom of the right side of the extension frame, and the right side of the connecting spring is fixedly connected to the heating shell.

[0010] By adopting the above technical solution, a limiting wheel is set in combination with hollow teeth. When in use, the passing tape can be limited by the limiting wheel in combination with the contact ring. Since it is hollow, the adhesion force of the tape to it will not be too strong. The extension frame set in combination with the connecting spring can press the heating shell when in use, so that it pushes the tape to fit the outside of the pipe.

[0011] The present invention is further configured as follows: an auxiliary rod is fixedly connected to the left side of the heating shell, and the left side of the auxiliary rod is slidably connected to the extension frame.

[0012] By adopting the above technical solution, an auxiliary rod is provided to limit the movement of the heating shell relative to the extension frame, thereby avoiding rotation or tilting that may cause abnormal use.

[0013] The present invention is further configured as follows: an oblique frame is fixedly connected to the left side of the guide frame, the bottom inside the oblique frame is rotatably connected to the outer shell, the bottom on the left side of the oblique frame is rotatably connected to a telescopic cylinder, and the telescopic end of the telescopic cylinder is rotatably connected to the contact ring.

[0014] The above technical solution is adopted, by setting an inclined frame for connecting the guide frame and the repair mechanism, and the telescopic cylinder is used to lift the repair mechanism relative to the pipeline or press the repair mechanism against the pipeline surface. When adhesive repair is required, the telescopic end of the telescopic cylinder is extended. At this time, the outer shell of the repair structure rotates along the inclined frame, and the heating shell part presses the tape to contact the pipeline surface.

[0015] The present invention is further configured as follows: the front and rear sides of the bottom of the guide frame are fixedly connected to coil frames, the two coil frames are respectively sleeved on the outsides of the two groups of support rings, an auxiliary motor is installed on the rear side of the rear coil frame, and the output end of the auxiliary motor is fixedly connected to the output shaft.

[0016] By adopting the above technical solution, a coil frame is set up. When connecting the guide frame and the support ring, the two coil frames can be clamped on the inner side of the two top rings or the bottom rings when the top ring and the bottom ring of the support ring are relatively opened to complete the installation of the guide frame and the support ring, and at the same time, it has the effect of controlling the distance between the two groups of support rings.

[0017] The present invention is further configured such that the outer side of the output shaft passes through two coil frames and is rotatably connected to the two coil frames, the outer side of the coil frame is fixedly connected to a friction wheel, and the two friction wheels are in contact with two friction rings respectively.

[0018] By adopting the above technical solution, an auxiliary motor is set up to cooperate with the output shaft. When it is inconvenient for a single person to rotate the guide frame, the auxiliary motor can be used to assist the guide frame in rotating. The auxiliary motor drives the output shaft to rotate on the inner side of the coil frame. At this time, the friction wheel connected to it will rub against the friction ring and rotate, so as to drive the coil frame and guide frame connected to it to rotate circumferentially.

[0019] The present invention is further configured as follows: a bolt is threadedly connected to the bottom of the coil frame, a top of the bolt passes through the bottom of the coil frame and is rotatably connected to a lower pressure frame, and the inner side of the lower pressure frame is rotatably connected to two rollers.

[0020] By adopting the above technical solution, by setting bolts to cooperate with the lower pressure frame, when connecting the coil frame and the support ring, the bolts can be rotated along the coil frame to increase the distance between the lower pressure frame and the roller and the friction wheel, so as to facilitate the plug-in fit between the structures, and after the connection, the lower pressure frame and the roller are pressed against the friction ring by rotating the bolts, while the other side of the friction ring is in contact with the friction wheel, so as to keep the structure free of gaps after installation and to enable normal friction transmission.

[0021] The present invention is further configured as follows: the front side of the coil frame is fixedly connected to an arc frame, the rear side of the bottom of the arc frame is rotatably connected to a pressure wheel, and the rear side of the pressure wheel is rotatably connected to the front side of the support ring.

[0022] By adopting the above technical solution, by setting up an arc frame in conjunction with a pressure wheel, the friction of the arc frame relative to the support ring can be reduced by the pressure wheel when the coil frame rotates relative to the support ring, so as to avoid excessive sliding friction and the coil frame being unable to drive the structure to rotate. The arc frame is set up to limit the structures to avoid relative displacement of the two sets of support rings during use.

[0023] The present invention is further configured as follows: the front side of the top ring is fixedly connected to a hinge part, the front side of the bottom ring is fixedly connected to the other end of the hinge part, the front side of the top ring is fixedly connected to a hook, the front side of the bottom ring is fixedly connected to a buckle, and the buckle and the hook are clamped.

[0024] By adopting the above technical solution, by setting a hinge, the top ring and the bottom ring can be opened relative to each other, so that the structure can be installed on the pipe or removed from the pipe, and the connection between the top ring and the bottom ring can be quickly connected or unlocked through buckles and blocks.

[0025] Compared with the prior art, the present invention provides a rapid repair composite leak detection device for heat pump pipelines, which has the following beneficial effects: The heat pump pipeline quick repair composite leak detection device can be directly installed on the outside of the heat pump pipeline by setting a support ring. When in use, the two sets of top rings and bottom rings can be relatively opened, and the top ring and bottom ring can be clamped on the outside of the heat pump pipeline. At this time, the rollers on the inner sides of the top ring and the bottom ring are in contact with the heat pump pipeline through the balls, and the detection probes arranged obliquely in the circumferential direction can continuously detect damage, leakage and cracks on the surface of the heat pump pipeline. The two sets of support rings also play the role of installing the repair mechanism. When in use, the repair mechanism can be installed on the outside of the two sets of support rings through the guide frame. When a defect to be repaired is detected on the outside of the heat pump pipeline, the personnel can hold the holding part of the right support ring. When the guide frame is rotated along the circumference of the support ring, the tape part of the tape roll will stick to the outside of the pipe. As the guide frame rotates, the tape roll is continuously pulled and rotates along the roll clamp, and the tape is continuously pulled out. At this time, the heating wire on the inside of the side shell heats the tape, causing it to initially melt to provide further adhesion so that it can be firmly adhered to the outside of the pipe and not easily loosened. After winding a certain number of times until the repair area is covered, the guide frame is stopped from moving, and the heating wire on the inside of the heating shell melts the tape, and the melted tape will be attached to the outside of the heating shell for subsequent use. At this time, the entire repair structure can be lifted from the outside of the pipe so that it is no longer in contact, and subsequent maintenance work can be carried out.

The rear sides of the top ring 101 and the bottom ring 102 are fixedly connected to a friction ring 103. The front sides of the top ring 101 and the bottom ring 102 are fixedly connected to a detection probe 104. The inner sides of the top ring 101 and the bottom ring 102 are fixedly connected to a roller frame 105. The inner side of the roller frame 105 is movably connected to a ball bearing. The inner sides of the right top ring 101 and the right bottom ring 102 are fixedly connected to a holding portion. By setting the support ring 1, the device can be directly installed on the outside of the heat pump pipeline. When in use, the two sets of top rings 101 and bottom rings 102 can be opened relatively, and the top ring 101 and bottom ring 102 can be clamped on the outside of the heat pump pipeline. At this time, the roller racks 105 on the inside of the top ring 101 and the bottom ring 102 are in contact with the heat pump pipeline through the balls, and the circumferentially inclined detection probe 104 can continuously detect damage, leakage and cracks on the surface of the heat pump pipeline. The two sets of support rings 1 also have the effect of installing the repair mechanism 3. When in use, the repair mechanism 3 can be installed on the outside of the two sets of support rings 1 through the guide frame 2.

[0030] Among them, the front and rear sides of the bottom of the guide frame 2 are fixedly connected with a coil frame 11, and the two coil frames 11 are respectively sleeved on the outside of the two groups of support rings 1, and an auxiliary motor is installed on the rear side of the rear coil frame 11. The output end of the auxiliary motor is fixedly connected with an output shaft 12. By setting the coil frame 11, when connecting the guide frame 2 and the support ring 1, the two coil frames 11 can be clamped on the inner sides of the two top rings 101 or the bottom ring 102 when the top ring 101 and the bottom ring 102 of the support ring 1 are relatively opened to complete the installation of the guide frame 2 and the support ring 1, and at the same time, it has the effect of controlling the distance between the two groups of support rings 1. The outer sides of the output shaft 12 respectively pass through the two coil frames 11 and are rotatably connected to the two coil frames 11. A friction wheel 13 is fixedly connected to the outside, and the two friction wheels 13 are in contact with the two friction rings 103 respectively. By setting an auxiliary motor to cooperate with the output shaft 12, the guide frame 2 can be assisted to rotate by the auxiliary motor when it is inconvenient for a single person to operate. The auxiliary motor drives the output shaft 12 to rotate on the inside of the coil frame 11. At this time, the friction wheel 13 connected thereto will rub against the friction ring 103 and rotate, so as to drive the coil frame 11 and the guide frame 2 connected thereto to rotate circumferentially. The bottom of the coil frame 11 is threadedly connected with a bolt 14, and the top of the bolt 14 passes through the bottom of the coil frame 11 and is rotatably connected to a lower pressure frame 15. The inner side of the lower pressure frame 15 is rotatably connected to two rollers 16. By setting the bolt 14 cooperates with the lower pressure frame 15. When the coil frame 11 and the support ring 1 are connected, the bolt 14 can be rotated along the coil frame 11 to increase the distance between the lower pressure frame 15 and the roller 16 and the friction wheel 13, so as to facilitate the plug-in fit between the structures, and after the connection, the lower pressure frame 15 and the roller 16 are pressed against the friction ring 103 by rotating the bolt 14, and the other side of the friction ring 103 is in contact with the friction wheel 13, so as to maintain the structure without gap after installation, and to perform friction transmission normally. The front side of the coil frame 11 is fixedly connected to the arc frame 17, and the rear side of the bottom of the arc frame 17 is rotatably connected to the pressure wheel 18, and the rear side of the pressure wheel 18 is rotatably connected to the front side of the support ring 1. By setting the arc frame 17 to cooperate with the pressure wheel 18, it is possible to When the coil frame 11 rotates relative to the support ring 1, the friction of the arc frame 17 relative to the support ring 1 is reduced by the pressure wheel 18 to avoid excessive sliding friction, which makes it difficult for the coil frame 11 to drive the structure to rotate. The arc frame 17 is set to limit the structures to avoid relative displacement of the two groups of support rings 1 during use. The front side of the top ring 101 is fixedly connected to a hinge 19, and the front side of the bottom ring 102 is fixedly connected to the other end of the hinge 19. The front side of the top ring 101 is fixedly connected to a hook, and the front side of the bottom ring 102 is fixedly connected to a buckle. The buckle and the hook are clamped. By setting the hinge 19, the top ring 101 and the bottom ring 102 can be opened relative to each other, so that the structure can be installed on or removed from the pipeline.The connection between the top ring 101 and the bottom ring 102 can be quickly connected or unlocked by means of buckles and hooks.

[0031] Working principle of this embodiment: When in use, the top ring 101 and bottom ring 102 are opened by hinges 19, and the support ring 1 is snapped onto the outside of the heat pump pipe. The hook and buckle are used to quickly connect. At this time, the ball bearings of the roller frame 105 contact the pipe to reduce friction. The circumferentially inclined detection probe 104 detects the pipe and provides a mounting base for the repair mechanism 3. The auxiliary motor of the rear winding frame 11 drives the output shaft 12 to rotate, driving the friction wheel 13 to rub against the friction ring 103, thereby driving the winding frame 11 and the guide frame 2 to rotate along the circumference of the pipe. When a defect is detected, the guide frame 2 drives the repair mechanism 3 to move and repair. When the support ring 1 is opened, the winding frame 11 is installed with the guide frame 2 and the spacing is controlled. By adjusting the bolts 14 at the bottom of the winding frame 11, the lower pressure frame 15 and roller 16 press against the friction ring 103, ensuring that there is no gap in the friction transmission. The arc frame 17 cooperates with the pressure wheel 18 to reduce rotational friction and prevent relative displacement of the support ring 1.

[0032] Example 2: Reference Figure 1-5 A quick repair composite leak detection device for heat pump pipelines also includes a repair mechanism 3, wherein the repair mechanism 3 includes a shell 31, a roll clamp 32 is fixedly connected to the inner side of the shell 31, and a tape roll 33 is sleeved on the outer side of the roll clamp 32. A contact ring 34 is fixedly connected to the front side of the shell 31, and a side shell 35 is fixedly connected to the bottom of the contact ring 34. A heat conducting plate 36 is fixedly connected to the right side of the side shell 35. A heating shell 37 is provided at the bottom of the side shell 35, and heating wires are provided on the inner sides of the heating shell 37 and the side shell 35. When a defect to be repaired is detected on the outside of the heat pump pipe, the personnel can hold the holding part of the right support ring 1. At this time, the guide frame 2 can be rotated circumferentially along the support ring 1. During rotation, the tape part of the tape roll 33 will stick to the outside of the pipe. As the guide frame 2 rotates, the tape roll 33 is continuously pulled and rotated along the roll clamp 32, and the tape is continuously pulled out. At this time, the heating wire on the inside of the side shell 35 heats the tape, causing it to initially melt to provide further adhesion so that it can be firmly adhered to the outside of the pipe and not easily loosened. After winding a certain number of times until the repair area is covered, the guide frame 2 is stopped from moving, and the heating wire on the inside of the heating shell 37 melts the tape, and the melted tape will be attached to the outside of the heating shell 37 for subsequent use. At this time, the entire repair structure can be lifted from the outside of the pipe so that it is no longer in contact, and subsequent maintenance work can be carried out.

[0033] The front side of the shell 31 is connected with a cover 4, and the tape roll 33 is made of silicone rubber tape material. By setting the cover 4, when the tape roll 33 needs to be replaced, the cover 4 can be opened to quickly install a new tape roll 33 inside the shell 31. The tape roll 33 made of silicone rubber tape has good bonding strength, strength and sealing, which can avoid water leakage at the repaired leak. The front side of the shell 31 is rotatably connected to the limiting wheel 5, and the outer side of the limiting wheel 5 is provided with a plurality of hollow teeth. The right side of the heating shell 37 is fixedly connected to a metal sheet, and the left side of the side shell 35 is fixedly connected to an extension frame 6. The bottom of the right side of the extension frame 6 is fixedly connected to a connecting spring 7. The right side of the connecting spring 7 is fixedly connected to the heating shell 37. By setting the limiting wheel 5 in conjunction with the hollow teeth, the passing tape can be limited by the limiting wheel 5 in conjunction with the contact ring 34 when in use. Because it is hollow, the adhesive force of the tape on it will not be too strong, and the extension frame 6 is provided. The cooperation connecting spring 7 can press the heating shell 37 when in use, so that it pushes the tape to fit the outside of the pipe. The left side of the heating shell 37 is fixedly connected to an auxiliary rod 8, and the left side of the auxiliary rod 8 is slidably connected to the extension frame 6. By setting the auxiliary rod 8, it is used to limit the movement of the heating shell 37 relative to the extension frame 6 to avoid rotation or tilting that causes abnormal use. The left side of the guide frame 2 is fixedly connected to an inclined frame 9, and the bottom inside the inclined frame 9 is rotatably connected to the outer shell 31. The bottom left side of the inclined frame 9 is rotatably connected to a telescopic cylinder 10, and the telescopic end of the telescopic cylinder 10 is rotatably connected to the contact ring 34. The inclined frame 9 is provided to connect the guide frame 2 and the repair mechanism 3. The telescopic cylinder 10 is used to lift the repair mechanism 3 relative to the pipe or press the repair mechanism 3 against the pipe surface. When adhesive repair is required, the telescopic end of the telescopic cylinder 10 is extended. At this time, the outer shell 31 of the repair structure rotates along the inclined frame 9, and part of the heating shell 37 will press the tape to contact the pipe surface.

[0034] Working principle of this embodiment: During repair, the operator holds the holding part of the support ring 1 and drives the guide frame 2 to rotate along the support ring 1. The tape of the tape roll 33 is pulled and adhered to the outside of the pipe. The heating wire in the side shell 35 initially melts it to enhance the adhesion and ensure a firm fit. After the repair area is covered, the heating wire in the heating shell 37 melts the tape, and the melted end is attached to the heating shell 37 for subsequent use. During this process, the limiting wheel 5 on the front side of the shell 31 cooperates with the hollow teeth and the contact ring 34 to limit the tape to avoid excessive adhesion. The extension frame 6 and the connecting spring 7 push the heating shell 37 to ensure that the tape fits tightly to the pipe. The auxiliary rod 8 prevents the heating shell 37 from tilting or rotating. The inclined frame 9 cooperates with the telescopic cylinder 10. During repair, the telescopic cylinder 10 extends, driving the outer shell 31 of the repair mechanism 3 to rotate around the inclined frame 9, so that the heating shell 37 presses down the tape to contact the pipe. After completion, the telescopic cylinder 10 contracts and lifts the mechanism. In addition, the cover 4 on the front side of the outer shell 31 facilitates the replacement of the tape roll 33 made of highly adhesive and sealing silicone rubber belt, effectively preventing water from leaking again at the leaking site.
