[0023] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0024] In this document, terms such as "upper, lower, left, right, inside, and outside" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also vary. Therefore, they cannot be understood as absolute limitations on the scope of protection. Moreover, relational terms such as "first" and "second" are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components. In addition, in the embodiments of the present invention, "above", "below", etc. include the numbers themselves.

[0025] The water pipe plugging device of this embodiment can quickly and conveniently seal the head end of a water pipe with a rib structure. The water pipe head end is melted by heating, and the water pipe head end is pressed tightly against the groove of the heating plate with force, so that the melted water pipe material can effectively wrap the exposed rib structure and fill the gap between the material and the rib structure, blocking water and other fluids from entering the inside of the water pipe, and achieving good sealing effect. Moreover, the designed Teflon coating can avoid the high-temperature melted water pipe material from sticking to the groove and residue, and is conducive to the separation of the two after the sealing is completed, resulting in a good sealing effect on the water pipe head end and fast and convenient operation.

[0026] Reference Figures 1 to 2 The water pipe plugging device of this embodiment is used to seal the head end of a water pipe 200. The water pipe 200 includes a pipe wall 6 and a channel 7 formed by the pipe wall 6. The channel 7 is used for the circulation of water or other fluids. The specific thickness of the pipe wall 6 and the size of the channel 7 can be adjusted according to the needs of the water supply and drainage use scenario and are not specifically limited here. In this embodiment, a rib structure 8 is provided within the pipe wall 6. Therefore, after cutting the water pipe 200, the cross-section will have residual rib structure 8, that is, the rib structure 8 is exposed at the head end of the water pipe 200. Specifically, the pipe wall 6 can be made of resin material, and the rib structure 8 can be made of steel wire.

[0027] The plugging device 100 of this embodiment includes a heating plate 1, which is provided with a heating wire 2. Specifically, the heating wire 2 can be provided inside and / or outside the heating plate 1. The heating wire 2 provides heat to the heating plate 1 to melt the head end of the water pipe 200. In a specific implementation of this embodiment, the heating wire 2 can be an electric heating wire.

[0028] A groove 3 is provided on one side of the heating plate 1. This groove 3 is used to accommodate the head end of the water pipe 200 when the head end of the water pipe 200 is sealed. A Teflon coating 4 is provided at least within this groove 3. This Teflon coating 4 prevents the high-temperature melted material of the water pipe 200 from adhering to the groove 3 and facilitates separation of the two after sealing. Specifically, the Teflon coating 4 can be provided only in the groove 3. Alternatively, in addition to providing the Teflon coating 4 within the groove 3, a Teflon coating 4 can also be provided near the groove 3 of the heating plate 1 to prevent some of the water pipe 200 material from overflowing the groove 3 and adhering to the heating plate 1 during sealing. To facilitate connection and separation with the head end of the water pipe 200 and to provide space for the Teflon coating 4, the width of the groove 3 is designed to be greater than the thickness of the pipe wall 6.

[0029] The plugging device 100 of this embodiment further includes a force-applying component 5. When plugging, the force-applying component 5 applies force in the direction in which the water pipe 200 is pressed against the groove 3. That is, when plugging the head end of the water pipe 200, the force-applying component 5 is used to press the water pipe 200 against the groove 3. Specifically, the force-applying component 5 of this embodiment only needs to be able to exert a force on the water pipe 200 to press against the groove 3 when plugging. For example, a push rod, a claw, or the like can be used. The position of applying force on the water pipe 200 can also be adjusted. For example, the force can be applied to the other end face of the plugged head end of the water pipe 200, or to a certain position in the middle of the water pipe 200.

[0030] When the plugging device 100 of this embodiment is used to plug the head end of the water pipe 200, the head end of the water pipe 200 is inserted into the groove 3 of the heating plate 1. Under the heat of the heating wire 2, the head end material of the water pipe 200 melts. At the same time, under the action of the force-applying component 5, the head end of the water pipe 200 is pressed against the groove 3. In this way, the melted head end material of the water pipe 200 can effectively wrap the exposed rib structure 8, and on the other hand, the melted material can also fill the gap between the rib structure 8, thereby reliably sealing the head end of the water pipe 200 and preventing water and other fluids from entering the interior of the water pipe 200 from the head end, thereby achieving a good sealing effect. In addition, the Teflon coating 4 on the groove 3 can prevent the melted head end material of the water pipe 200 from adhering to the inner wall of the groove and leaving residue. Moreover, when the plugging is completed, the water pipe 200 can be easily separated from the groove 3, making the plugging operation convenient and quick.

[0031] In the specific implementation of this embodiment, the groove 3 is designed as a trapezoidal groove, and the width of the groove 3 gradually decreases from the outside of the heating plate 1 to the inside. In other words, the groove 3 is designed to be trumpet-shaped and open outward. In this way, when the head end of the water pipe 200 enters or leaves the groove 3, the inclined groove walls on both sides can play a certain guiding role, facilitating the insertion and removal of the head end of the water pipe 200.

[0032] Specifically, the groove 3 is designed as an isosceles trapezoidal groove, and the top length of the groove 3 is designed to be 1 / 3 to 2 / 3 of the bottom length of the groove 3. The depth of the groove 3 is designed to be 1 to 15 cm to adapt to the size of common water pipes 200 and has good versatility.

[0033] In the specific implementation of this embodiment, the heating wire 2 is disposed within the interior of the heating plate 1. A heating groove is provided on the side of the heating plate 1 facing away from the groove 3, and the heating wire 2 is disposed within the heating groove. Thus, by forming a groove structure within the heating plate 1 to accommodate the heating wire 2, the heat generated by the heating wire 2 can be provided to the heating plate 1 itself to a greater extent, thereby improving the heat utilization efficiency of the heating wire 2 and reducing the energy consumption of the plugging device 100.

[0034] Specifically, the heating wires 2 are spirally arranged within the heating tank to accommodate more heating wires 2 within a limited space. This allows for higher heat output from the heating plate 1, making it suitable for plugging the ends of water pipes 200 with thicker or higher-temperature pipe wall materials. The heating plate 1 has a temperature range of 100-260°C, providing an appropriate temperature range for different pipe wall materials.

[0035] In the specific implementation of this embodiment, the heating wire 2 includes a preheating phase and an operating phase. The head end of the water pipe 200 is softened during the preheating phase. That is, when using the plugging device 100 of this embodiment to plug the head end of the water pipe 200, the head end of the water pipe 200 is first preheated and softened, resulting in a good sealing effect at the head end of the water pipe 200 after plugging. Of course, in other implementations, a separate preheating component (not shown) can be designed to soften the head end of the water pipe 200.

[0036] Specifically, the thickness of the Teflon coating 4 is 0.1 to 5 mm to adapt to different materials and thicknesses of the pipe wall 6. The size of the heating plate 1 can be set according to the diameter of the water pipe 200. For example, the cross-section of the heating plate 1 is designed to be rectangular, and the width of the heating plate 1 is designed to be 50 to 5000 cm.

[0037] Taking a DN400 water supply pipe as an example, when sealing the head end of water pipe 200, the head end of water pipe 200 is first preheated before sealing. Then, under the force of the force-applying component 5, the head end of water pipe 200 is inserted into the groove 3 that has reached a preset temperature. Due to the non-stick properties of the Teflon coating 5, after heating and melting, the water pipe 200 can be easily removed from the groove 3 without any residue, effectively sealing the head end of water pipe 200 with gaps and exposed rib structure 8. Compared with existing sealing methods, this method has the advantages of simple and practical structure, convenient operation, high efficiency, and low cost. The sealed water pipe 200 is also of safe and reliable quality.
