Description

Technical Field

[0001] This application relates to the technical field of leak detection devices, and more particularly to a leak detection device for a floor heating system under a plastic floor. Background Art

[0002] A floor heating system uses the entire floor as a radiator. Through the hot water in the floor radiation layer, the entire floor is evenly heated. Utilizing the law of heat storage of the floor itself and the upward radiation of heat, heat is conducted from bottom to top to achieve the purpose of heating.

[0003] After a leak occurs in the floor heating system, the acoustic wave method is often used to accurately locate the leak point of the floor heating. An acoustic wave detector is used to locate the leak point based on the difference in the acoustic wave performance of the leak point.

[0004] The acoustic wave method for leak detection can only locate the leak point of the floor heating pipeline system under floor tiles or concrete floors. When encountering floors such as plastic floors, floor coverings, and wooden floors, due to the blocking effect of these floors on weak acoustic waves, the acoustic wave positioning method cannot accurately determine the leak point location. At this time, the acoustic wave detector cannot detect the acoustic wave change of the leak point. Therefore, if acoustic wave detection is used, the floor needs to be removed, which is time-consuming, laborious, and requires a large investment. Summary of the Utility Model

[0005] In order to detect the pipeline leak point without removing the floor, this application provides a leak detection device for a floor heating system under a plastic floor.

[0006] This application provides a leak detection device for a floor heating system under a plastic floor, adopting the following technical solutions:

[0008] A transport vehicle;

[0009] A hydrogen storage tank, arranged on the transport vehicle, and a hydrogen delivery pipe is connected to the hydrogen storage tank;

[0010] A nitrogen pressurization tank, arranged on the transport vehicle, and a nitrogen delivery pipe is connected to the nitrogen pressurization tank;

[0011] A pressure gauge, arranged on the transport vehicle, and a transmission pipe is connected to the pressure gauge;

[0013] An infusion pipe, connected to the connecting member;

[0014] A detection unit, movably arranged on the transport vehicle.

[0015] By adopting the above technical solution, by integrating components such as a hydrogen storage tank, a nitrogen pressurizing tank, a pressure gauge and connecting parts on a transport vehicle, a fast and convenient leak detection function for the floor heating system is realized. The hydrogen storage tank and the nitrogen pressurizing tank inject hydrogen and nitrogen into the floor heating pipeline through the connecting parts, and the pressure gauge monitors the pressure change in the pipeline in real time to ensure accurate testing; the detection part is movably arranged and can move above the floor heating pipeline without disassembling the floor. When the detection part detects hydrogen and nitrogen, the floor heating pipeline under the floor is in a leaking state, which is beneficial to detecting the pipeline leak point without removing the floor.

[0018] Optionally, a fixed clamp is arranged on the side of the perfusion pipe away from the connecting part.

[0019] By adopting the above technical solution, the fixed clamp arranged on the side of the perfusion pipe away from the connecting part facilitates the stable connection of the perfusion pipe to the floor heating pipeline or other test interfaces, reduces the possibility of the perfusion pipe falling off due to the pressure change in the pipeline during the test, and thus ensures the stability and safety of the test.

[0022] The first arc-shaped clamping plate is provided with a fixing component. When the second arc-shaped clamping plate is flipped to abut against the first arc-shaped clamping plate, the fixing component fixes the second arc-shaped clamping plate.

[0023] By adopting the above technical solution, by arranging multiple support columns and the equipped arc-shaped clamping plate system on the transport vehicle, the stable support and fixation of the hydrogen storage tank and the nitrogen pressurizing tank are realized. The design of the arc-shaped clamping plate can adapt to tanks with different diameters. The cooperation between the first arc-shaped clamping plate and the second arc-shaped clamping plate, as well as the locking function of the fixing component, ensure the stability of the hydrogen storage tank and the nitrogen pressurizing tank during transportation and testing, and reduce the possibility of damage caused by vibration or collision.

[0025] The fixing post is rotatably connected to the first arc-shaped clamping plate, and the fixing strip is arranged on the outer peripheral side of the fixing post and is perpendicular thereto;

[0026] The second arc-shaped clamping plate is formed with a sliding hole for the fixing post and the fixing strip to pass through. When the second arc-shaped clamping plate abuts against the first arc-shaped clamping plate, rotate the fixing post. At this time, the side of the fixing strip close to the first arc-shaped clamping plate abuts against the second arc-shaped clamping plate.

[0027] By adopting the above technical solution, the specific design of the fixing component, including the rotatable fixing post and the vertically arranged fixing strip, realizes the quick and reliable fixing of the arc-shaped clamping plate by rotating the fixing post to make the fixing strip abut against the second arc-shaped clamping plate.

[0030] By adopting the above technical solution, the first arc-shaped clamping plate and the second arc-shaped clamping plate are connected by a hinge shaft, and a linkage shaft is arranged to connect the adjacent hinge shafts up and down, realizing the synchronous opening and closing of multiple groups of arc-shaped clamping plates and improving the operation efficiency. At the same time, the setting of multiple groups of arc-shaped clamping plates enhances the supporting force for the tank body and further ensures the stability of the tank body.

[0031] Optionally, rubber layers are respectively arranged on the arc-shaped concave side walls of the first arc-shaped clamping plate and the second arc-shaped clamping plate.

[0032] By adopting the above technical solution, rubber layers are arranged on the arc-shaped concave side walls of the first arc-shaped clamping plate and the second arc-shaped clamping plate, effectively reducing the friction and wear between the hydrogen storage tank and the nitrogen pressurization tank, and at the same time increasing the clamping tightness and sealing performance, reducing the possibility of the hydrogen storage tank and the nitrogen pressurization tank sliding or leaking during the fixing process.

[0033] Optionally, a push rod is arranged on the transport vehicle.

[0034] By adopting the above technical solution, arranging a push rod on the transport vehicle facilitates the operator to move the entire leak detection device to different test locations, improving the portability and flexibility of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] The following Figures 1-3 further describes the present application in detail with reference to the

[0043] The embodiment of the present application discloses a leak detection device for a floor heating system under a plastic floor.

[0044] Referring to Figure 1 and Figure 2 , the leak detection device includes a transport vehicle 1, a hydrogen storage tank 2, a nitrogen pressurization tank 3, a pressure gauge 4, a connecting member 5, a perfusion pipe 6 and a detection part 7.

[0045] Specifically, the hydrogen storage tank 2 and the nitrogen pressurizing tank 3 are both firmly arranged on the transport vehicle 1. The hydrogen storage tank 2 is connected and fixed with a hydrogen delivery pipe 21, and the nitrogen pressurizing tank 3 is connected and fixed with a nitrogen delivery pipe 31. The pressure gauge 4 is connected and fixed with a transmission pipe 41, and the pressure gauge 4 is movably placed on the transport vehicle 1 for real-time monitoring of the pressure change of the gas. The transport vehicle 1 is fixedly connected with a push rod 15, and the transport vehicle 1 can be pushed by the push rod 15 when in use, so as to facilitate the movement of the hydrogen storage tank 2 and the nitrogen pressurizing tank 3.

[0046] In this embodiment, the connecting piece 5 is a four-way connection having four connecting ports. The hydrogen delivery pipe 21, the nitrogen delivery pipe 31, the transmission pipe 41 and the perfusion pipe 6 are respectively fixedly connected to the four-way connection, and the hydrogen delivery pipe 21, the nitrogen delivery pipe 31, the transmission pipe 41 and the perfusion pipe 6 are respectively connected to a corresponding connecting port of the four-way connection to ensure that the gas can flow smoothly. A fixed clamp 61 is provided on the side of the filling pipe 6 away from the connecting piece 5. When leak detection is performed, the filling pipe 6 is connected to the water distributor of the floor heating system, and then the water distributor of the floor heating system is fixed by the fixed clamp 61 to reduce the possibility of leakage during the gas injection process; then, the hydrogen storage tank 2 and the nitrogen pressurization tank 3 are opened. At this time, the hydrogen storage tank 2 transmits hydrogen to the four-way through the hydrogen transmission pipe 21, and the nitrogen pressurization tank 3 transmits nitrogen to the four-way through the nitrogen transmission pipe 31; then part of the hydrogen and nitrogen in the four-way are transmitted to the pressure gauge 4 through the transmission pipe 41. At this time, the pressure gauge 4 enters the pressure monitoring state. At the same time, hydrogen and nitrogen are poured into the water distributor of the floor heating system through the filling pipe 6, and dispersed to the floor heating pipeline through the water distributor. The detection unit 7 is movably placed on the transport vehicle 1. The detection unit 7 is a hydrogen-nitrogen gas detector. After hydrogen and nitrogen are poured into the pipes of the floor heating system, the detection unit 7 is picked up and moved on the ground above the pipes of the floor heating system. When hydrogen and nitrogen are detected, the pipe under the floor at the detection point is in a leakage state, thereby accurately determining the leakage point.

[0047] See also Figure 1 and Figure 3 Furthermore, in order to facilitate the installation and fixation of the hydrogen storage tank 2 and the nitrogen pressurized tank 3 on the transport vehicle 1, a plurality of support columns 11 are fixedly connected to the transport vehicle 1. The support columns 11 correspond to the hydrogen storage tank 2 and the nitrogen pressurized tank 3 respectively, and a connecting column is fixedly connected between the connected support columns 11. A group of first arc-shaped clamping plates 12 and second arc-shaped clamping plates 13 are provided on each support column 11. Each group of first arc-shaped clamping plates 12 and second arc-shaped clamping plates 13 can closely fit the shapes of the hydrogen storage tank 2 and the nitrogen pressurized tank 3 to provide a stable support.

[0048] There are two first arc-shaped clamping plates 12 and two second arc-shaped clamping plates 13 in each group, which are arranged at intervals up and down. The first arc-shaped clamping plate 12 is fixedly connected to the vertical side wall of the support column 11. The first arc-shaped clamping plate 12 includes a first arc-shaped plate 123 and a first connecting plate 124. There are two first connecting plates 124, which are respectively fixedly connected to both ends of the first arc-shaped plate 123. The two first connecting plates 124 are in the same vertical plane, and the arc concave side of the first arc-shaped plate 123 faces away from the support column 11.

[0049] The second arc-shaped clamping plate 13 includes a second arc-shaped plate 132 and a second connecting plate 133. There are two second connecting plates 133, which are respectively fixedly connected to both ends of the second arc-shaped plate 132. The two second connecting plates 133 are in the same vertical plane, and the arc concave side of the second arc-shaped plate 132 faces away from the support column 11.

[0050] A hinge shaft 121 is rotatably connected to one of the first connecting plates 124. One of the second connecting plates 133 is fixedly connected to the hinge shaft 121, and the second arc-shaped clamping plate 13 can be flipped in the direction of approaching or departing from the support column 11. A linkage shaft 122 is fixedly connected between the upper and lower hinge shafts 121, so that the upper and lower second arc-shaped clamping plates 13 can be linked. When the second connecting plates 133 are in contact with each other, the arc concave side of the second arc-shaped plate 132 faces the arc concave side of the first arc-shaped plate 123, and rubber layers 14 are respectively fixedly connected to the arc concave side of the second arc-shaped plate 132 and the arc concave side of the first arc-shaped plate 123.

[0051] In order to further enhance the clamping stability, a fixing component 8 is provided on the first arc-shaped clamping plate 12. When the second arc-shaped clamping plate 13 is flipped to abut against the first arc-shaped clamping plate 12, the fixing component 8 can quickly fix the second arc-shaped clamping plate 13. This design not only ensures the stability of the hydrogen storage tank 2 and the nitrogen pressurizing tank 3 during transportation and use, but also greatly simplifies the operation steps.

[0052] The fixing component 8 includes a fixing column 81 and a fixing strip 82. The fixing column 81 is rotatably connected to the first connecting plate 124 far from the hinge shaft 121, and the hinge shaft 121 is perpendicular to the first connecting plate 124. The fixing strip 82 is fixedly connected to the outer peripheral side of the fixing column 81, and the fixing strip 82 is perpendicular to the fixing column 81. A sliding hole 131 is formed in the second connecting plate 133 far from the hinge shaft 121. When the second arc-shaped clamping plate 13 is flipped to abut against the first arc-shaped clamping plate 12, the fixing column 81 and the fixing strip 82 slide through the sliding hole 131, and then the fixing strip 82 is toggled to rotate the fixing column 81 until the fixing strip 82 is misaligned with the sliding hole 131. The side of the fixing strip 82 close to the first connecting plate 124 abuts against the second connecting plate 133, realizing the fixation of the first arc-shaped clamping plate 12 and the second arc-shaped clamping plate 13, and completing the fixed installation of the hydrogen storage tank 2 and the nitrogen pressurizing tank 3.

[0053] The implementation principle of the leakage detection device for the floor heating system under the plastic floor in the embodiment of the present application is as follows:

[0054] When leak detection, connect the filling pipe 6 to the water distributor of the floor heating system, then open the hydrogen storage tank 2 and the nitrogen pressure tank 3. At this time, the pressure gauge 4 monitors the pressure of hydrogen and nitrogen. At the same time, hydrogen and nitrogen are poured into the water distributor of the floor heating system through the filling pipe 6, and dispersed to the floor heating pipe through the water distributor. After that, pick up the detection part 7 and move it on the ground above each pipe of the floor heating system. When hydrogen and nitrogen are detected, the pipe under the floor of the detection point is in a leaking state, so the leak point can be accurately determined. The whole detection process is simple, and the pipeline leak point can be detected without removing the floor.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
