Description

Technical Field

[0001] This utility model relates to the field of heating pipeline testing technology, and in particular to a heating pipeline insulation and airtightness testing device. Background Technology

[0002] A heating network, also known as a heating pipeline, is a network of heating pipes that run from heat sources such as boiler rooms, direct-fired generator rooms, and heating centers to buildings. Multiple heating pipes form a network to meet the city's heating needs. When heating pipes transport heat in the city, they follow the city's planned pipeline routes, which requires multiple pipes to be connected. During the pipe connection process, air leaks in the heating pipes can occur.

[0003] A search revealed a Chinese patent publication number CN216952655U, which discloses a municipal heating pipeline insulation and airtightness testing device, including a first mounting plate and a second mounting plate. The second mounting plate is engaged with the side of the first mounting plate, and a second mounting block is mounted on the second mounting plate. The second mounting block is engaged within the first mounting block. A fixing block is mounted on the outside of the first mounting plate, and a compression spring is installed inside the fixing block. One end of the compression spring is connected to a moving block.

[0004] During installation, the first mounting plate can be suspended on the heating pipe, and then the second mounting block on the second mounting plate can be engaged with the first mounting block. Pulling the pull rope will move the push block upward, pushing the second mounting block to fully engage with the first mounting block. After releasing the pull rope, the buffer spring will cause the push block to rebound and fix the second mounting block. This makes the installation of the detection device simple. However, its disassembly and assembly require pulling both pull ropes simultaneously. Therefore, it is inconvenient for a single worker to disassemble and assemble, and multiple people are needed to assist each other, which wastes manpower and is inconvenient to operate.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: A heating pipeline insulation airtightness testing device, such as Figures 1 to 3 As shown, the system includes a first arc-shaped plate 1 and a second arc-shaped plate 2 interconnected by multiple connecting components. Sealing rubber strips are fixed to the inner walls of both ends of the first arc-shaped plate 1 and the second arc-shaped plate 2. Magnets 3 are fixed to both sides of the inner wall of the first arc-shaped plate 1. Detection components are provided on the side walls of the second arc-shaped plate 2. The connecting components include a first connecting plate 4 and a second connecting plate 5. The first connecting plate 4 is fixedly connected to both ends of the second arc-shaped plate 2, and the second connecting plate 5 is fixed to both ends of the first arc-shaped plate 1. The second connecting plate 5 is L-shaped. 4 is attached to the inner wall of the connecting plate 2 5. One end of the connecting plate 2 5 has multiple sliding cavities 7. The inner wall of the sliding cavity 7 is slidably fitted with a limiting rod 6. One end of the connecting plate 4 has a slot 10 that is limited and fitted to one end of the limiting rod 6. Two limiting plates 11 are fixed to the outer wall of the limiting rod 6. Two fixing plates 9 are fixed to the inner wall of the sliding cavity 7. The fixing plates 9 and the limiting plates 11 are staggered. A spring 8 is sleeved on the outer wall of the sliding cavity 7. The two ends of the spring 8 are connected to the limiting rod 6 and the connecting plate 2 5, respectively.

[0027] During testing, the first arc-shaped plate 1 is first attached to the outer wall of the pipe. The magnet 3 magnetically attracts the outer wall of the pipe to fix the position of the first arc-shaped plate 1. At this time, one end of the limiting rod 6 is away from the connecting plate 2 5, and the spring 1 8 is stretched and deformed. At this time, the limiting plate 11 is located on the side of the fixing plate 9 close to the spring 1 8 and is aligned with the position of the fixing plate 9, limiting the limiting rod 6. Then, the second arc-shaped plate 2 is placed on the other side of the pipe and attached. One end of the limiting rod 6 is aligned with the connecting plate 1 4. Then, the limiting rod 6 is rotated so that the fixing plate 9 no longer limits the limiting rod 6. The spring 1 8 pulls the limiting rod 6 to insert into the slot 10 to fix the first arc-shaped plate 1 and the second arc-shaped plate 2. At this time, the detection component can be used for detection. During disassembly, the limiting rod 6 is pulled so that the limiting plate 11 is misaligned with the fixing plate 9 and passes over the fixing plate 9. Then, the limiting rod 6 is rotated to limit the limiting rod 6. When all the limiting rods 6 are disengaged from the connecting plate 1 4, the first arc-shaped plate 1 and the second arc-shaped plate 2 can be separated.

[0028] By incorporating connecting components, it is not necessary to simultaneously detach the connection between the two ends of the first arc plate 1 and the second arc plate 2. A single operator can gradually disengage the connection between the first arc plate 1 and the second arc plate 2, making the operation convenient.

[0029] By setting the magnet 3, the first arc plate 1 can be magnetically fixed to the surface of the pipe, avoiding the need for manual fixing of the first arc plate 1 after it is placed on the outer wall of the pipe due to gravity and other factors.

[0030] Example 2: A heating pipeline insulation airtightness testing device. This example is based on Example 1 and makes the following improvements, such as... Figure 4 As shown, the detection assembly includes a fixing block 12 and a detection cavity 13. The fixing block 12 is fixed to the outer wall of one side of the second arc-shaped plate 2. The detection cavity 13 is opened inside the fixing block 12, and one end of the detection cavity 13 is connected to the interior of the second arc-shaped plate 2. A movable plate 14 is slidably fitted on the inner wall of the detection cavity 13. One end of the movable plate 14 is connected to a spring 15, and the other end of the spring 15 is connected to the inner wall of the detection cavity 13. A groove 17 is opened on the side wall of the detection cavity 13. Multiple LED beads 16 are fixed on the outer wall of the fixing block 12. Multiple conductive contacts 18 are fixed on the inner wall of the groove 17. The conductive contacts 18 are electrically connected to the LED beads 16 one by one. A conductive contact 19 is fixed on the side wall of the movable plate 14. The conductive contact 19 is slidably sealed with the inner wall of the groove 17, and the conductive contact 19 is electrically connected to the battery.

[0031] When a leak occurs in the pipeline, gas enters the detection chamber 13, pushing the moving plate 14 to move along the detection chamber 13 towards one end. The spring 15 is compressed and deformed, and the conductive contact 19 moves along the groove 17. As the moving plate 14 moves, it contacts multiple conductive contacts 18 to conduct electricity. As the moving distance of the moving plate 14 increases, multiple LED beads 16 light up. By observing the lighting of the LED beads 16, it can be determined whether there is a leak and the extent of the leak.

[0032] By setting multiple LED beads 16 and conductive contact pieces 18, as the moving plate 14 moves a distance, the multiple LED beads 16 light up respectively. By observing the lighting of the LED beads 16, it is possible to determine whether there is a leak and the extent of the leak.

[0033] Working principle: During testing, the first arc-shaped plate 1 is first attached to the outer wall of the pipe. The magnet 3 magnetically attracts the outer wall of the pipe, fixing the position of the first arc-shaped plate 1. At this time, one end of the limiting rod 6 is away from the connecting plate 2 5, and the spring 1 8 is stretched and deformed. At this time, the limiting plate 11 is located on the side of the fixing plate 9 close to the spring 1 8 and is aligned with the position of the fixing plate 9, limiting the position of the limiting rod 6. Then, the second arc-shaped plate 2 is placed on the other side of the pipe and attached. One end of the limiting rod 6 is aligned with the connecting plate 1 4. Then, the limiting rod 6 is rotated so that the fixing plate 9 no longer limits the limiting rod 6. The spring 1 8 pulls the limiting rod 6 to insert into the slot 10 to fix the first arc-shaped plate 1 and the second arc-shaped plate 2. When a leak occurs in the pipe, gas will enter. The moving plate 14 is pushed into the detection chamber 13 and moves along the detection chamber 13 to one end of the detection chamber 13. The spring 15 is compressed and deformed, and the conductive contact 19 moves along the groove 17. As the moving plate 14 moves, it contacts and conducts electricity with multiple conductive contacts 18. As the moving distance of the moving plate 14 increases, multiple LED beads 16 light up. By observing the lighting of the LED beads 16, it can be determined whether there is a leak and the degree of leakage. When disassembling, the limiting rod 6 is pulled to make the limiting plate 11 misalign with the fixed plate 9 and pass over the fixed plate 9. Then the limiting rod 6 is rotated to limit the limiting rod 6. When multiple limiting rods 6 are disengaged from the connecting plate 4, the first arc plate 1 and the second arc plate 2 can be separated.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
