Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe penetration through walls, and in particular to a novel device for sealing through walls of building drainage pipes. Background Technology
[0002] Drainage pipe penetration sealing refers to taking a series of measures to ensure the sealing and waterproofing between the pipe and the wall when the drainage pipe passes through the wall, preventing water leakage and damage to the wall structure, and thus ensuring the safety of people's lives and property. The sealing usually uses silicone sealant or waterproof mortar. The former is particularly suitable for damp environments such as kitchens and bathrooms due to its water resistance, mildew resistance and strong adhesion, while the latter is more suitable for horizontal and vertical pipe sealing due to its excellent water resistance, mildew resistance and impermeability. Ignoring this sealing step may not only cause indoor dampness and mold, but also create safety hazards and even provide opportunities for criminals. Therefore, the sealing operation must be strictly implemented in the construction of drainage horizontal pipe penetration through the wall to maintain the comfort and safety of the indoor environment.
[0003] However, conventional drainage pipes are often sealed with cement. After sealing, the cement takes a certain amount of time to solidify. During this time, the vibration generated by the water flow inside the pipe or external influences can easily cause the pipe to shift, resulting in gaps between the cement and the pipe, thus making conventional sealing ineffective.
[0004] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The novel wall-penetrating sealing device for building drainage pipes provided by this utility model adopts the following technical solution:
[0007] A novel wall-penetrating sealing device for building drainage pipes includes a pipe body. One end of the pipe body is snapped with a connecting frame, and one end of the connecting frame is movably connected to a sealing material. A support frame is rotatably mounted on one side of the connecting frame. A heater is fixedly connected to the surface of the support frame. One end of the heater is connected to a gas tank via a gas pipe. A fixing frame is snapped with the surface of the gas tank. One end of the fixing frame is fixedly connected to one end of the connecting frame, and a box is fixedly mounted at the bottom of the fixing frame. The center of the connecting frame and the center of the pipe body are on the same straight line.

[0008] Preferably, the sealing material is KNM17 thermosetting sealing material, and the center of the sealing material is on the same straight line as the center of the pipe body, and the inner wall of the sealing material is movably connected to the surface of the pipe body.

[0010] Preferably, one end of the support frame is fixedly connected to a handle, and one end of the handle is rotatably mounted to the surface of the fixed frame.
[0011] Preferably, a support rod is welded to one end of the connecting frame, and a sliding frame is fixedly connected to the bottom end of the connecting frame. Two sliders are slidably installed on the inner wall of the sliding frame.

[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model involves installing a connecting frame at one end of a pipe body, with sealing material applied to the surface of the connecting frame. A heater is mounted at one end of the connecting frame via a support frame, and one end of the heater is connected to a gas tank via a gas pipe. This allows the heater to heat the sealing material, liquefying it and using it to seal the connection between the pipe body and the building.

[0022] The following is in conjunction with the appendix Figure 1 —4. This utility model will be described in further detail.
[0023] This utility model discloses a novel wall-penetrating sealing device for building drainage pipes, referring to... Figure 1 - Figure 2 The system includes a pipe body 1, with a connecting frame 2 installed at one end of the pipe body 1. A sealing material 10 is installed on the surface of the connecting frame 2. A support frame 3 is rotatably installed at one end of the connecting frame 2. A heater 4 is installed at one end of the support frame 3. One end of the heater 4 is connected to a gas tank 5 via a gas pipe. A box 7 is installed on the surface of the gas tank 5 via a fixing frame 6. The box 7 facilitates the placement of excess gas tanks 5 or other items. The gas tank 5 provides natural gas to the heater 4 to generate a flame. The heater 4 heats the sealing material 10, causing it to liquefy and then block the connection between the pipe body 1 and the building, effectively improving the convenience of sealing the drainage pipe.
[0024] Reference Figure 2The KNM17 thermosetting sealant 10 is connected to the surface of the pipe body 1 so that when the KNM17 thermosetting sealant 10 reaches a certain temperature, it transforms from a plastic body into an elastic body, thereby achieving the purpose of sealing the leak. The surface of the connecting frame 2 is slidably connected with the mounting ring 9 so that it can be moved to fit against the surface of the building, thereby preventing the sealant 10 from leaking out after melting. One end of the support frame 3 is equipped with a handle 8 so that the support frame 3 can be rotated by the handle 8, which facilitates the control of the heater 4 to rotate and heat the sealant 10 at different positions.
[0025] Reference Figure 3 - Figure 4 A support rod 11 is installed at one end of the connecting frame 2, and a limiting roller 14 is installed at the bottom end of the connecting frame 2 via a sliding frame 12 and a slider 13. This allows the tube 1 to be fixed by the support rod 11 and the limiting roller 14, preventing the tube 1 from shifting during sealing. The surface of the slider 13 slides against the inner wall of the sliding frame 12, allowing adjustment of the rubber limiting roller 14 at one end of the slider 13. This facilitates limiting tubes 1 of different sizes. A spring 15 is installed between the two sliders 13, allowing the spring 15 to push the slider 13 and keep the limiting roller 14 at one end of the slider 13 in contact with the inner wall of the tube 1, effectively improving the fixing effect of the limiting roller 14.
[0026] The implementation principle of this utility model is as follows: A connecting frame 2 is installed at one end of the pipe body 1. A sealing material 10 is installed on the surface of the connecting frame 2. A heater 4 is installed at one end of the connecting frame 2 with the help of a support frame 3. One end of the heater 4 is connected to a gas tank 5 through a gas pipe so that the gas tank 5 can provide natural gas to the heater 4 to generate a flame. The heater 4 heats the sealing material 10, so that the sealing material 10 liquefies and blocks the connection between the pipe body 1 and the building. The KNM17 thermosetting sealing material 10 is connected to the surface of the pipe body 1 so that when the KNM17 thermosetting sealing material 10 reaches a certain temperature, it changes from a plastic body to an elastic body, thereby achieving the purpose of sealing the leak. An installation ring 9 is slidably connected to the surface of the connecting frame 2 so that it can be moved and fit against the surface of the building, thereby avoiding the leakage of the sealing material 10 after melting. A handle 8 is installed at one end of the support frame 3 so that the support frame 3 can be rotated with the handle 8, which facilitates the control of the heater 4 to heat the sealing material 10 at different positions.
[0027] A support rod 11 can also be installed at one end of the connecting frame 2, and a limiting roller 14 is installed at the bottom end of the connecting frame 2 with the sliding frame 12 and the slider 13, so as to fix the tube 1 with the support rod 11 and the limiting roller 14 and prevent the tube 1 from shifting when sealing. The surface of the slider 13 slides with the inner wall of the sliding frame 12, so as to adjust the rubber limiting roller 14 at one end of the slider 13, which is convenient for limiting tubes 1 of different sizes. A spring 15 is installed between the two sliders 13, so as to push the slider 13 with the spring 15 and keep the limiting roller 14 at one end of the slider 13 in contact with the inner wall of the tube 1, effectively improving the fixing effect of the limiting roller 14.
[0028] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
