Description

Technical Field

[0001] This utility model relates to the field of underfloor heating equipment technology, and in particular to a pressure-resistant structure for underfloor heating pipes. Background Technology

[0002] With the continuous progress of society, in order to speed up the installation of flooring and subsequent adjustments and replacements, raised floors are mostly used. This means that a support frame is used instead of the original concrete to support the floor, and the underfloor heating pipes are laid in the gap between the raised floor and the ground, and are attached to the floor. In this way, the heat from the underfloor heating pipes can be transferred outward through the floor they are attached to. However, this raises an important issue, namely, pressure resistance. Because the floor is often stepped on, it will dent or sink, which will put pressure on the underfloor heating pipes located between the floor and the ground, causing them to deform or break.

[0003] Currently, a Chinese patent application with patent number "CN202320641458.X" discloses a high-pressure-resistant dry underfloor heating module, including an all-aluminum heat-conducting plate. A high-density extruded polystyrene insulation board B is installed on the top of the all-aluminum heat-conducting plate. The lower surface of the high-density extruded polystyrene insulation board B is provided with mounting grooves B and rectangular grooves. Its structure is reasonable. By utilizing the elastic buffering and pressure-resistant effect of the pressure-resistant mechanism, the high-density extruded polystyrene insulation board B, together with the pressure-resistant mechanism, supports and resists the pressure on the floor. At the same time, under the long-term influence of heavy objects, the pressure-resistant mechanism can distribute the pressure, reducing the possibility of insufficient support and collapse caused by the high-density extruded polystyrene insulation board B directly supporting the floor. However, it ignores a crucial issue, namely, it cannot directly protect the underfloor heating pipes. That is, in order to avoid affecting the normal heat dissipation of the underfloor heating pipes, most of them set up a support structure around the underfloor heating pipes to distribute the pressure received by the underfloor heating pipes, but it cannot eliminate the pressure directly received by the underfloor heating pipes.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were discovered: High heat loss and poor compressive stability: Existing underfloor heating pipe compressive devices mainly rely on placing them around the underfloor heating pipes to distribute the weight of the floor when stepped on, thus forming indirect compressive resistance. However, because the compressive devices themselves have a certain volume, and to ensure the compressive stability of the underfloor heating pipes, they need to be evenly distributed around the pipes, thus occupying a certain amount of space, reducing the area required for laying the underfloor heating pipes, and affecting the laying density. This can lead to uneven heating and cooling of the floor surface. In addition, existing underfloor heating pipes have high heat loss. Taking a room as an example, in order to ensure that heat can be felt everywhere, the underfloor heating pipes need to cover every part of the room. However, during normal use, the user's activity range is limited, often concentrated in the living room area. This causes heat to be rapidly dissipated in some inactive areas, resulting in a large amount of resource loss. To adjust the degree of heat dissipation according to the activity range of people, it is necessary to install them in separate areas, which also causes resource damage. Therefore, we propose an underfloor heating pipe compressive structure. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a pressure-resistant structure for underfloor heating pipes, solving the technical problems of high heat loss and poor pressure resistance stability in existing underfloor heating pipe pressure-resistant devices during use.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A pressure-resistant structure for underfloor heating pipes, the pressure-resistant structure comprising: A fitting fitted over the outside of the underfloor heating pipe includes an end cap and a pipe sleeve that interlock, with the end cap and pipe sleeve fitted over the upper and lower sides of the underfloor heating pipe respectively. The end cap has an outer plate on each side, and the outer plate corresponds to the inner plate on both sides of the sleeve. When the end cap is connected to the sleeve, the outer plate covers the outside of the inner plate, and the outer through groove on the outer plate and the inner through groove on the inner plate intersect each other. When the end cap and the sleeve are fitted together, the outer through groove on the outer plate and the inner through groove on the inner plate are connected to each other.

[0007] Preferably, the end cap is made of a thermally conductive material and is attached to the floor tiles; the sleeve is made of a thermal insulation material. When the end cap is fitted onto the underfloor heating pipe, heat is transferred from the underfloor heating pipe along the end cap to the floor tiles.

[0008] Preferably, each side of the inner plate is provided with a side plate, and the two side plates are provided with vertically extending guide grooves on the opposite side. Each side of the outer plate is connected to a pin, and the pins correspond to the guide grooves. When the end cap and the sleeve are connected, the pins on the outer side of the outer plate are located in the guide grooves.

[0009] Preferably, the inside of both sides of the guide groove is provided with corresponding protrusions, and the protrusions are located near the bottom of the guide groove, and the area enclosed between them and the guide groove is a movable groove; The outer wall of the protrusion is arc-shaped. Under the pressing action, the pin passes through the protrusion and enters the movable groove, and can slide in the movable groove. When the pin is engaged with the protrusion, the outer plate located between the two outer through grooves covers the outside of the inner through groove; conversely, when the pin is engaged with the bottom of the guide groove, the outer through groove and the inner through groove on the outer plate are interconnected, and heat is transferred from the underfloor heating pipe through the outer through groove and the inner through groove to the floor tiles.

[0010] Preferably, the bottom of the end cap is provided with two arc-shaped elastic compression pieces, which are attached to the outer wall of the underfloor heating pipe. When the end cap is attached to the pipe sleeve, the elastic compression pieces on the inner side of the end cap are deformed by the compression of the underfloor heating pipe.

[0011] Preferably, water-absorbing strips are embedded in the inner walls of the end cap and the inner walls of the sleeve. The water-absorbing strips are filled with water-absorbing resin and are located near the end of the end cap or the sleeve. When they absorb water and expand, they can fill the gap between the underfloor heating pipe and the end cap or the sleeve.

[0012] Preferably, a water-absorbing tray is embedded inside the end cap, and the water-absorbing tray is connected to a water-absorbing strip installed on the inner wall of the end cap, so that the absorbed water can enter the water-absorbing tray along the water-absorbing strip. The absorbent plate has a magnet at its center, and when the magnet absorbs water and expands, it pushes the magnet upward.

[0013] Preferably, the pressure-resistant structure also includes a detector corresponding to the end cap, and the detector includes a device cylinder, and a magnet is provided at the center of the device cylinder. The magnet is connected to the detection end of the tension sensor through a traction rope. When the magnet and the magnet attract each other, the position change of the magnet can be determined by the value detected by the tension sensor.

[0014] (III) Beneficial Effects 1. Because it uses corresponding end caps and pipe sleeves as the protective structure for the underfloor heating pipes, it can directly cover the outer wall of the underfloor heating pipes, thus forming a whole with the pipes and directly supporting them. Secondly, when the end caps and pipe sleeves are connected, the outer plates on both sides of the end caps cover the inner plates on both sides of the pipe sleeves. Figure 9As shown, when the end cap is compressed, the outer plates on both sides of the end cap abut against the outer wall of the pipe sleeve, preventing the end cap from descending further and thus locking the position between the end cap and the pipe sleeve. This protects the underfloor heating pipe located between them. Therefore, it effectively solves the technical problem of poor pressure resistance stability of existing underfloor heating pipe pressure-resistant devices during use, thereby realizing the pressure resistance of the underfloor heating pipe. At the same time, it not only does not occupy the original laying space of the underfloor heating pipe, but also can directly perform pressure resistance treatment on the underfloor heating pipe, thereby improving the stability of pressure resistance.

[0015] 2. By utilizing the pressure exerted on the floor to compress the underfloor heating pipes, upward-sloping through holes are made on both the outer and inner connecting plates. When the underfloor heating pipes are compressed, the through holes between the inner and outer connecting plates correspond to each other. Figure 10 As shown, heat can then be dissipated through the through holes to the floor. Conversely, when the underfloor heating pipe is not subjected to external pressure, the through holes on the inner and outer connecting plates are interlaced, preventing heat from dissipating outwards and reducing heat loss in non-human-occupied areas. Therefore, this effectively solves the technical problem of high heat loss in existing underfloor heating pipe pressure-resistant devices, thereby improving the targeted dissipation of heat and increasing energy utilization. This ensures that heat is concentrated and accurately delivered. Secondly, since the pipe sleeve is made of non-thermal-conducting material, heat transfer to the ground can be reduced to a certain extent. In addition, the end caps made of thermally conductive material can conduct heat from the underfloor heating pipe to the floor, thus maintaining the floor at a certain temperature. Therefore, it will not cause discomfort to users when they come into contact with it. 3. By installing absorbent strips filled with absorbent resin (or other materials that expand upon absorbing water, not limited to absorbent resin) on the inner walls of the pipe sleeve and end caps near the edges, water can be absorbed when the underfloor heating pipe leaks, filling the gap between the pipe and the sleeve or end cap, thus mitigating or even blocking the leak. Next, an absorbent tray, also filled with absorbent resin, is connected to the absorbent strips. Water can flow along the strips into the tray, where it expands and pushes the magnetic plate upwards, reducing the distance between the magnetic plate and the floor. Therefore, when a magnet or iron object is placed on the floor, the magnetic plate attracts it. By observing the strength of the attraction, the magnetic plate can be estimated to have moved upwards, thus determining if the underfloor heating pipe has cracked. This avoids the need to wait until a serious leak occurs before detection, reducing the difficulty of inspection. Attached Figure Description

[0019] This application provides a pressure-resistant structure for underfloor heating pipes, effectively solving the technical problems of high heat loss and poor pressure resistance stability in existing underfloor heating pipe pressure-resistant devices. Because it uses corresponding end caps and pipe sleeves as the protective structure for the underfloor heating pipe, it can directly cover the outer wall of the pipe, thus forming a unified whole and directly supporting the pipe. Furthermore, when the end caps and pipe sleeves are connected, the outer plates on both sides of the end caps cover the positions of the inner plates on both sides of the pipe sleeve. Figure 9 As shown, when the end cap is compressed, the outer plates on both sides of the end cap abut against the outer wall of the pipe sleeve, preventing the end cap from descending further. This locks the position between the end cap and the pipe sleeve, thus protecting the underfloor heating pipe located between them. This achieves the pressure resistance of the underfloor heating pipe. At the same time, it does not occupy the original laying space of the underfloor heating pipe, and it can also directly perform pressure resistance treatment on the underfloor heating pipe, thereby improving the stability of pressure resistance.

[0020] Example 1: The technical solution in this application example effectively solves the technical problems of large heat loss and poor compressive stability of existing underfloor heating pipe pressure-resistant devices during use. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides a pressure-resistant structure for underfloor heating pipes, such as... Figure 13 As shown, the compression-resistant structure is set on a raised floor structure; this is just one example and not the only one. Figure 13 As shown, any type of raised floor can be used, meaning that when the floor is stepped on, the floor tiles will only shift downwards to a certain extent under pressure, providing a basis for subsequent heat transfer. This pressure-resistant structure mainly consists of three parts: a fitting fitted onto the underfloor heating pipe 1, a heat-conducting structure to improve energy efficiency, and a detection structure for detecting whether the underfloor heating pipe 1 is leaking. Firstly, the fitting can be fitted onto the outer wall of the underfloor heating pipe 1 to provide pressure resistance when the underfloor heating pipe 1 is compressed. To facilitate its fitting onto the outside of the underfloor heating pipe 1, it is designed as two parts that can interlock. This allows it to be fitted onto the upper and lower sides of the underfloor heating pipe 1 respectively, such as... Figure 2 As shown, it is then connected via a snap-fit ​​structure, thus covering the underfloor heating pipe 1, as follows. Figure 1As shown, when pressed, the two structural parts abut against each other, completely encasing the underfloor heating pipe 1 and forming a whole to protect it. Secondly, there is a heat-conducting structure to reduce heat loss in unnecessary areas. Based on the connector, each of its two structural parts has a through-hole for heat conduction. In the initial state (when the underfloor heating pipe 1 is not compressed), the two through-holes are staggered, i.e., they block each other. At this time, heat can only be transferred to the floor tiles through the connector. However, when compressed, the two structural parts approach and abut against each other, and their through-holes connect, allowing heat to be transferred outwards through the through-holes. This increases the heat at the pressure point, concentrating the heat to the seated area and improving energy efficiency. Thirdly, and finally, is a structure for detecting the underfloor heating pipe 1. The leak detection structure is another major improvement we've made. By using a water-absorbing resin or similar material that expands upon absorbing water as the support structure for the magnet block 42 (or iron sheet), its expansion upon absorbing water causes it to move upwards, reducing the distance between the magnet block 42 (or iron sheet) and the floor tile. Then, another magnet is placed close to the floor tile. The magnet, under the attraction between itself and the magnet block 42 (or iron sheet), is drawn towards the floor tile. The closer the magnet is, the stronger the attraction. Therefore, the change in magnetic force can be used to determine if a leak has occurred, improving the timeliness of detection and allowing for early detection of any ruptures in the underfloor heating pipe 1, avoiding the situation where leaks are only discovered after large-scale leaks have occurred. The specific structure is as follows: The socket, the main structure of this application, is used to provide support for subsequent mechanisms or equipment, and also to provide sufficient support for the underfloor heating pipe 1, so as to protect the underfloor heating pipe 1 from further damage and blockage when it is squeezed; it is divided into two parts. The first part is the cover plate assembly structure (i.e., cover plate assembly 2), which is mainly composed of several end caps 21 connected to each other. The end caps 21 are in direct contact with the back of the floor tiles. In order to accommodate the bending and deformation of the underfloor heating pipe 1, an arc-shaped connecting pipe 22 is connected between two adjacent end caps 21. The connecting pipe is made of flexible material, such as... Figure 3 As shown, when the underfloor heating pipe 1 bends or deforms, the torque is transmitted to the connecting pipe 22 connected between the end caps 21. The bending or deformation of the connecting pipe 22 eliminates the force caused by the bending of the underfloor heating pipe 1. In contrast, the bottom cover structure (i.e., the bottom cover assembly 3) is mainly composed of several pipe sleeves 31 connected to each other. The pipe sleeves 31 are in contact with the ground. Similarly, in order to adapt to the changes caused by the bending of the underfloor heating pipe 1, a connecting pipe 32 made of flexible material is connected between two adjacent pipe sleeves 31.

[0021] In order to stably cover the outside of the underfloor heating pipe 1, the pipe sleeve 31 and the end cap 21 need to be connected to form a whole. Therefore, we provide an outer connecting plate 23 on each side of the end cap 21, and the outer connecting plate 23 corresponds to the inner connecting plate 34 on both sides of the pipe sleeve 31. When the end cap 21 and the pipe sleeve 31 are connected, the outer connecting plate 23 covers the outside of the inner connecting plate 34, as shown below. Figure 9 As shown, based on the overlapping arrangement of the inner plate 34 and the outer plate 23, a side plate 37 is provided on each side of the inner plate 34, and a vertically extending guide groove 38 is provided on the opposite side of the two side plates 37, as shown. Figure 4 As shown, the corresponding outer plate 23 has a pin 25 connected to each side, and the pins 25 correspond to the guide grooves 38. This allows the pins 25 on the outer side of the outer plate 23 to be positioned in the guide grooves 38 when the end cap 21 is connected to the sleeve 31. Although this forms an insertion state, it still has a limiting structure. Therefore, corresponding protrusions 39 are provided on the inner walls of both sides of the guide groove 38, and the protrusions 39 are located near the bottom of the guide groove 38. Figure 4 As shown in the enlarged view, the area enclosed between the protrusion 39 and the guide groove 38 is a movable groove. After the pin 25 is inserted into the guide groove 38, it moves along the guide groove 38. Then, the end cap 21 is pressed, and the pressure is transmitted to the pin 25 through the outer plate 23. At this time, under the pressing action, the pin 25 passes through the protrusion 39 and enters the movable groove, where it can slide. To facilitate the pin 25 entering the movable groove, the outer wall of the protrusion 39 is designed to be arc-shaped. Therefore, when the pin 25 is pressed against the protrusion 39, it can enter the movable groove enclosed by the protrusion 39 and the guide groove 38 along the guide groove 38. In this way, the end cap 21 and the sleeve 31 can be connected together, forming a shape like... Figure 11 The state shown in (b) to (c) is such that the active slot has a certain space so that the end cap 21 can interact within a certain range, providing a foundation for the subsequent heat conduction structure. In addition, the inner plate 34 has an embedded groove 36 near the side plate 37. The reason for setting the embedded groove 36 is that the edge of the outer plate 23 can fit with the inner plate 34.

[0022] The heat-conducting structure, based on the socket, has an outer through groove 24 and an inner through groove 35 respectively on the outer plate 23 and the inner plate 34, such as... Figure 4 As shown, the outer through groove 24 and the inner through groove 35 are on the same side; as shown, when the pin 25 and the protrusion 39 are in contact (i.e., when no one is stepping on the floor), the outer plate 23 located between the two outer through grooves 24 covers the outside of the inner through groove 35, as shown. Figure 10As shown in the upper half of the structure, the through slots on the outer plate 23 and the inner plate 34 are blocked by each other, preventing heat from spreading outward through the through slots. When heat can be transferred outward through the inner through slot 35 on the inner plate 34, it is blocked by the outer plate 23, thus reducing the heat loss and retaining the heat. Conversely, when the pin 25 is in contact with the bottom of the guide slot 38 (i.e., when someone steps on the floor), the outer through slot 24 and the inner through slot 35 on the outer plate 23 are interconnected, such as... Figure 10 As shown in the lower half of the structure, heat is transferred from the underfloor heating pipe 1 through the outer groove 24 and the inner groove 35 to the floor tiles, thus transferring more heat to the pressed floor tiles, causing them to heat up rapidly. This precisely transfers heat to the location of people, improving resource utilization. To reduce heat loss before conduction and to improve accurate heat conduction, the end cap 21, which is directly connected to the floor tiles, and the connecting pipe 22 used to connect the end cap 21 are both made of thermally conductive material. This allows heat to pass through the underfloor heating pipe 1 to the end cap 21, and then be transferred from the end cap 21 to the floor tiles. Conversely, the pipe sleeve 31, which is in contact with the ground, and the connecting pipe 32 used to connect the pipe sleeve 31 are both made of thermal insulation material. This way, when heat is transferred to the ground, it is blocked by the pipe sleeve 31, which to some extent confines the heat within the underfloor heating pipe 1, thereby reducing heat loss and improving energy utilization. To assist in the reset of end cap 21 (i.e., the state of separation from sleeve 31), such as Figure 11 In the state shown in (c), the support column structure of the raised floor tiles is used. We also set two arc-shaped and corresponding elastic compression plates 26 at the bottom of the end cap 21. The elastic compression plates 26 are attached to the outer wall of the underfloor heating pipe 1. When the end cap 21 is attached to the pipe sleeve 31, the elastic compression plates 26 on the inner side of the end cap 21 are deformed by the compression of the underfloor heating pipe 1. At this time, the elastic compression plates 26 begin to store force during deformation. When the pressure decreases or disappears, the end cap 21 is lifted upward under the action of the elastic compression plates 26, thereby resetting the end cap 21 to reduce heat loss in non-compression positions. This method is only one, and other structures that can separate the end cap 21 from the pipe sleeve 31, such as springs, can also be used. This example refers to providing a feasible implementation scheme.

[0023] In the specific implementation process, the installation and use of the sleeve 31 is divided into three steps, as follows: Step 1, Installing pipe sleeve 31: Directly install pipe sleeve 31 onto underfloor heating pipe 1, such as... Figure 11 In the middle (a) time, all the sequentially connected pipe sleeves 31 are fitted onto the underfloor heating pipe 1 in the same way and distributed along the shape of the underfloor heating pipe 1; The second step is the installation of the end cap 21: After the pipe sleeve 31 is installed, connect the end cap 21 to the pipe sleeve 31 installed on the underfloor heating pipe 1, as follows: Figure 11 As shown in (b), during docking, the outer plates 23 on both sides of the end cap 21 correspond to the inner plates 34 on both sides of the sleeve 31, and the pins 25 on both sides of the outer plates 23 correspond to the guide grooves 38 on the side plates 37. Then, the end cap 21 can be pressed towards the sleeve 31. At this time, the outer plates 23 are inserted into the sleeve 31 along the gap between the two side plates 37, and the pins 25 on both sides of the outer plates 23 slide towards the bottom along the guide grooves 38. Since there are protrusions 39 on the inner walls of both sides of the guide grooves 38 near the bottom, and the surface of the protrusions 39 is arc-shaped, as shown in (b). Figure 4 As shown, when the pin 25 slides along the guide groove 38 to the position of the protrusion 39, by pressing, the pin 25 is inserted below the protrusion 39, thereby entering the movable groove formed between the protrusion 39 and the guide groove 38; The third step is applying pressure: In actual use, when the end cap 21 is stepped on, the end cap 21 moves towards the sleeve 31 under pressure until the pin 25 is in contact with the bottom of the guide groove 38. At this point, the elastic compression piece 26 deforms and begins to store force. At this time, the outer through groove 24 and the inner through groove 35 on the outer plate 23 are connected to each other. Figure 10 As shown in the lower half of the structure, heat is transferred from the underfloor heating pipe 1 through the outer channel 24 and the inner channel 35 to the floor tiles. This allows more heat to be transferred to the pressed floor tiles, causing them to heat up rapidly. This precise heat transfer to the location of people improves resource utilization. When no one is walking on the floor, the end cap 21 is lifted upwards by the elastic compression piece 26, thus resetting the end cap 21. At this time, the outer plate 23, located between the two outer channels 24, covers the outside of the inner channel 35. Figure 10 As shown in the upper half of the structure, the through slots on the outer plate 23 and the inner plate 34 are blocked by each other, and heat cannot be transmitted outward through the through slots. When heat can be transmitted outward through the inner through slot 35 on the inner plate 34, the heat is blocked by the outer plate 23, thereby reducing the heat that cannot be dissipated, and thus the heat is retained. Example

[0024] Based on Example 1, this application provides an implementation scheme for early detection of leaks in underfloor heating pipes. The overall concept is as follows: During the use of underfloor heating pipe 1, it was discovered that significant leaks, specifically flooding (such as water seeping into the tile grout, floor warping, or water seeping through the drainage system and into the floor below), only occurred. This already caused considerable damage. Furthermore, existing detection methods rely on heat distribution, using thermal imaging to observe whether there are large-scale temperature anomalies (circular temperature distribution) at the leak location. However, this method can only detect significant leaks, thus relying on reactive measures. Therefore, we decided to conduct a comprehensive inspection of underfloor heating pipe 1 based on the aforementioned findings and proposed solutions. The specific structure is as follows: like Figure 7 and Figure 8 As shown, absorbent strips are first embedded in the inner walls of the end cap 21 and the pipe sleeve 31 (absorbent strip 33 is installed on the inner wall of the end cap 21, and absorbent strip 43 is installed on the inner wall of the pipe sleeve 31). The absorbent strips are filled with a water-absorbing resin or other diluting and expanding material. This material is not limited to this one; other materials with water absorption and expansion properties can also be used. The reason for using water-absorbing resin is that, in addition to expanding after absorbing water, it can also prevent the absorbed water from leaking out. Therefore, water-absorbing resin is preferred. When the underfloor heating pipe 1 is damaged, the water in the underfloor heating pipe 1 flows out from the gap. If the damage is in the space enclosed by the connecting pipe 22 and the connecting pipe 32, the water flows along the space between the connecting pipe and the underfloor heating pipe 1. The water moves towards the end cap 21 and the pipe sleeve 31. When the water encounters the absorbent strip on the inner wall of the end cap 21 or the pipe sleeve 31, the water is absorbed, and the absorbent resin inside the absorbent strip begins to expand and extend towards the damaged area of ​​the underfloor heating pipe 1, which slows down the leakage rate of the underfloor heating pipe 1 to a certain extent and provides sufficient time for subsequent inspection and remediation. When the damage occurs in the space enclosed by the end cap 21 or the pipe sleeve 31, the water flows along the gap between the pipe sleeve 31 and the underfloor heating pipe 1 towards the edge of the pipe sleeve 31 until it contacts the absorbent strip at the edge of the pipe sleeve 31. Similarly, the absorbent resin inside the absorbent strip absorbs water and expands, filling the gap between the underfloor heating pipe 1 and the end cap 21, as well as between the underfloor heating pipe 1 and the pipe sleeve 31, thereby blocking the leakage of the underfloor heating pipe 1 to a certain extent.

[0025] Based on the above, we embed a water-absorbing tray 41 (the interior of the water-absorbing tray 41 is also filled with water-absorbing resin) inside the end cap 21, and the water-absorbing tray 41 is connected to the water-absorbing strip installed on the inner wall of the end cap 21. In this way, the water absorbed by the water-absorbing strip can be transferred to the water-absorbing tray 41, thereby causing the water-absorbing tray 41 to absorb water and expand. In addition, since a magnet block 42 is provided at the center of the water-absorbing tray 41, when the magnet block 42 absorbs water and expands, it can be pushed upward, thereby shortening the distance between the magnet block 42 and the floor tile. Figure 8As shown, this serves as a signal that the underfloor heating pipe 1 is leaking. If this signal can be detected or observed in a timely manner, it can be determined whether the underfloor heating pipe 1 is leaking. To allow space for the water suction plate 41, as... Figure 7 and Figure 8 As shown, a reserved groove 27 is opened on the top of the end cap 21 to allow the water suction tray 41 and the magnet block 42 to have enough room to move.

[0026] To acquire this signal, we designed a simple detector. Besides this method, other devices capable of receiving or detecting this signal can also be used; details are as follows: The detector includes a cylindrical device tube 51 (taking a cylinder as an example). A disc-shaped magnet 53 is disposed at the center of the device tube 51. This magnet 53 can slide along a groove on the inner wall of the device tube 51. Figure 12 As shown, the magnet 53 is connected to the detection end of the tension sensor 52 via a traction rope 54 (made of flexible material to avoid affecting the traction of the magnet 53). Therefore, when the magnet 53 moves, the tension can be transmitted to the tension sensor 52 through the traction rope 54. The position of the magnet 42 is then determined by the value detected by the tension sensor 52. Because it is combined with the characteristic of the magnet 42 absorbing water and moving upward, when the water absorption plate 41 absorbs water and drives the magnet 42 to move upward, the distance between the magnet 42 and the floor tile is shortened. Thus, when the tension sensor 52 with the magnet 53 moves to the position of the magnet 42, the magnetic force it receives increases, which can be directly observed by the tension sensor 52.

[0027] In the specific implementation process, when the underfloor heating pipe 1 leaks, the water moves along the space between the connecting pipe and the underfloor heating pipe 1 towards the end cap 21 and the pipe sleeve 31, and comes into contact with the water-absorbing strip on the inner wall of the end cap 21 or the pipe sleeve 31. The water is absorbed, and the water-absorbing resin inside the water-absorbing strip begins to expand, extending towards the damaged underfloor heating pipe 1, which slows down the leakage rate of the underfloor heating pipe 1 to a certain extent, providing sufficient time for subsequent inspection and remediation. At the same time, the water absorbed by the water-absorbing strip is transferred to the water-absorbing plate 41 connected to it, causing the water-absorbing plate 41 to absorb water and expand. In addition, since a magnet block 42 is set at the center of the water-absorbing plate 41, when the magnet block 42 absorbs water and expands, it can push the magnet block 42 upward, thereby shortening the distance between the magnet block 42 and the floor tile. Figure 8 As shown, this is a signal that the underfloor heating pipe 1 is leaking.

[0028] During testing, the device cylinder 51 with the magnet 53 is placed on the floor tile and moved. When it moves to the position of the magnet block 42 in its normal state, the magnet block 42 attracts the magnet 53 to move downwards, and this movement is transmitted to the tension sensor 52 through the traction rope 54, thereby applying a tension force to the tension sensor 52. Since the magnet block 42 is far from the surface of the floor tile, the magnet 53 will only move slightly. Conversely, when the water suction plate 41 absorbs water and moves the magnet block 42 upwards to shorten the distance between the magnet block 42 and the floor tile, the magnetic force on the magnet 53 increases due to the distance (i.e., the magnetic force increases when the distance decreases). This increase can be observed directly by the tension sensor 52. Therefore, by simply observing the change in the value detected by the tension sensor 52, it is possible to determine whether there is a leak in the underfloor heating pipe 1.

[0029] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
