Description

Technical Field

[0001] This utility model relates to the field of water heating pipe wiring technology, and in particular to a high-efficiency water heating pipe wiring device. Background Technology

[0002] Traditional electric underfloor heating is relatively inefficient, while water-based underfloor heating is more energy-saving and environmentally friendly. In recent years, converting coal-fired or traditional high-energy-consuming underfloor heating systems into energy-efficient electric water-based underfloor heating has gradually become a trend. This new type of water-based underfloor heating method heats the water by inserting heating wires through existing water pipes, without damaging the floor, making it both energy-saving and convenient.

[0003] However, there are several challenges in inserting heating wires into existing plumbing pipes. First, the length of the heating wire and the type of plumbing pipe will affect the insertion effect. If the heating wire is too long or the plumbing pipe uses a complex structure such as a U-shaped pipe, it is difficult to achieve precise control of the suction and the wire's movement through the pipe.

[0004] Secondly, the commonly used method is to use a circulating pump to increase the suction inside the water heating pipes, and rely on the suction to complete the insertion of the heating wires. However, due to the limited suction range of the circulating pump, it cannot meet the needs of inserting heating wires over long distances. These technical problems seriously restrict the promotion and application of new water heating technology. Utility Model Content

[0031] The following is in conjunction with the appendix Figures 1-6 The embodiments of this utility model will be described in detail below.

[0032] Reference Figures 1-6 As shown, the high-efficiency wiring device for water heating pipes includes a wiring box 1, a water storage tank 10 installed inside the wiring box 1, and a wiring device installed at the bottom of the wiring box 1. A wiring pipe 11 is detachably installed at the upper end of the wiring box 1, and the wiring pipe 11 extends into the water storage tank 10.

[0033] By utilizing the water flow within the water storage tank 10 and through a threading device, the pipeline is threaded into the water heating pipe via the threading pipe 11, thus achieving the installation of the water heating pipe.

[0034] Reference Figure 2 and Figure 3As shown, the cable threading device includes a circulation pump 12, which is installed at the bottom of the cable threading box 1. The water inlet of the circulation pump 12 is connected to a main pipe 13, and the other end of the main pipe 13 is connected to an exhaust pipe 15 through a tee pipe. The upper end of the exhaust pipe 15 extends to the bottom of the water storage tank 10, and an exhaust electric control valve 16 is installed on the exhaust pipe 15.

[0035] The inlet of the circulating pump 12 is connected to a main pipe 2 17. The main pipe 2 17 is connected to a horizontal pipe 18 through a tee pipe 2. An exhaust valve 2 19 is installed on the horizontal pipe 18. The other end of the horizontal pipe 18 is connected to a connecting pipe 20 through a tee pipe 3. A transfer pipe 21 is connected between the tee pipe 3 and the tee pipe 1. A connecting pipe 23 is installed on the transfer pipe 21. The other end of the tee pipe 2 is connected to a connecting pipe 23. The upper end of the connecting pipe 23 extends to the bottom of the water storage tank 10. An inlet valve 24 is installed on the connecting pipe 23.

[0036] A conduit 26 is connected to the bottom of the water storage tank 10, and the lower end of the conduit 26 extends through to the side wall of the conduit box 1 below the water storage tank 10.

[0037] The two ends of the plumbing pipe are connected to the connecting pipe 20 and the wiring conduit 26, respectively. Before wiring, the air in the plumbing pipe needs to be purged. For details, refer to... Figure 4 As shown, open the exhaust control valve 16 and exhaust control valve 29, then start the circulation pump 12, so that the water in the water storage tank 10 flows through the exhaust pipe 15, through the exhaust control valve 16, and then through the tee pipe 1 into the main pipe 13, and then into the circulation pump 12, and is discharged from the main pipe 2 17. It then flows through the tee pipe 2, the horizontal pipe 18, the exhaust control valve 2 19, the tee pipe 3 and the connecting pipe 20 in sequence into the water heating pipe, pushing the gas in the water heating pipe to be discharged from the other side, that is, the gas is pushed into the conduit 26, and then enters the water storage tank 10 through the cylinder 27 and is discharged.

[0038] Reference Figure 5 As shown, after the air in the plumbing pipes is purged, the exhaust valve 16 and exhaust valve 29 are closed, and the liquid inlet valve 22 and liquid inlet valve 24 are opened. The inlet of the circulation pump 12 will generate suction to draw the liquid from the plumbing pipes. The liquid flows through the following route: connecting pipe 20, three-way pipe 3, liquid inlet valve 122, transfer pipe 21, three-way pipe 1, and main pipe 13 before entering the circulation pump 12. Then, it enters the water storage tank 10 through main pipe 27, three-way pipe 2, connecting pipe 23, and liquid inlet valve 24, completing one cycle. At the same time, the negative pressure is formed due to the liquid being drawn from the plumbing pipes, and the water level in the water storage tank 10 is high enough, that is, higher than the height of the cylinder 27, so that the water in the water storage tank 10 passes through the cylinder 27 and the conduit 26 in sequence before entering the plumbing pipes. At this time, the water flow circulation in the plumbing pipes is completed.

[0039] Based on the above conditions, an environment is provided for pipeline intersection.

[0040] Reference Figure 6 As shown, a cylinder 27 is inserted through the bottom of the water storage tank 10. The cylinder 27 has a hollow mesh structure, and the bottom of the cylinder 27 is connected to the conduit 26. The lower end of the conduit 11 is inserted into the cylinder 27, which facilitates the discharge of gas in the water heating pipe through the conduit 11 and the cylinder 27. At the same time, during the wiring process, it is ensured that the water flow in the water storage tank 10 continuously enters the cylinder 27 and the conduit 11, so that the pipeline moves with the water flow in the water heating pipe.

[0041] The lower outer wall of the conduit 11 is provided with an annular protrusion 28, which is placed on the upper end of the cylinder 27. The side wall of the conduit 11 below the annular protrusion 28 is provided with several through holes 29. Water flows through the cylinder 27 and the through holes 29 into the conduit 11 and then flows into the conduit 26.

[0042] Reference Figure 1 As shown, a column 30 is installed on the side wall of the cable box 1, and a horizontal rotating rod 31 is installed on the top of the column 30. A coil with the cable wound on it is fitted onto the horizontal rotating rod 31.

[0043] The horizontal rotating rod 31 is located above the conduit 11, and the end of the horizontal rotating rod 31 facing away from the column 30 can be detachably fitted with a limiting side plate 32.

[0044] The process of installing the reel is as follows: first, remove the limiting side plate 32, then put the reel on the horizontal rotating rod 31, and then install the limiting side plate 32 on the end of the horizontal rotating rod 31 to prevent the reel from coming out of the horizontal rotating rod 31.

[0045] Based on the environment provided by the above-mentioned pipeline insertion, when one end of the pipeline wound on the coil is introduced into the conduit 11, the pipeline can flow with the water in the conduit 26, then enter the water heating pipe, and then exit from the other end, thus completing the pipeline insertion.

[0046] Based on the above, as the pipeline moves within the plumbing system, if the pipeline is too long or the plumbing system uses a complex structure such as a U-shaped pipe, it becomes difficult to achieve precise control of suction and pipe penetration. A circulating pump 12 is used to enhance the suction of the plumbing system to precisely drive the pipeline through. However, due to the limited suction lift of the circulating pump 12, it cannot meet the requirements for long-distance pipeline penetration. Therefore, referring to... Figure 2 and Figure 3As shown, this utility model has a drain pipe 25 connected between the connecting pipe 20 and the main pipe 13. The upper end of the drain pipe 25 is connected to the connecting pipe 20 through a tee pipe 4, and the lower end of the drain pipe 25 is connected to the main pipe 13 through a tee pipe 5. Both ends of the drain pipe 25 are closed plate structures, and several perforations of different diameters are opened on the closed plates.

[0047] Specifically, by connecting the drain pipe 25, water from the plumbing pipes enters the connecting pipe 20, creating a vortex siphon effect that further enhances the suction power. In addition, the diameter of the perforations at both ends of the drain pipe 25 can be adjusted according to the length of the pipeline. The smaller the diameter, the stronger the vortex siphon effect, increasing the suction power and improving the pipeline penetration effect.

[0048] It should be noted that, by Figure 2 and Figure 3 It is understood that although the drainage tube 25 shown in the figure is an L-shaped structure, this is only one shape structure represented in this application and is not limited to the one shown in the figure.

[0049] During construction, after the water and heating pipes for a certain area are laid out, this equipment needs to be moved to another area. That is, the conduit 26 is disconnected from the water and heating pipes. At this time, the water in the storage tank 10 will be discharged through the cylinder 27 and the conduit 26. Therefore, referring to... Figure 3 As shown, the present invention has a pneumatic control valve 33 installed on the conduit 26 for controlling the opening and closing of the conduit 26.

[0050] Reference Figure 3 As shown, a water pump 34 is installed at the bottom of the wiring box 1. The inlet and outlet ends of the water pump 34 are connected to an inlet hose 35 and an outlet hose 36, respectively. The inlet hose 35 extends to the outside of the wiring box 1, and the other end of the outlet hose 36 extends to the top of the water storage tank 10. By starting the water pump 34, water from a pre-prepared bucket is drawn into the water storage tank 10 through the inlet hose 35 and the outlet hose 36, enabling automatic liquid replenishment.

[0051] Secondly, since the water heating pipes are standardized, this utility model can calculate the laying length of the water heating pipes based on the amount of water pumped from the water tank by the water pump 34 and the specifications and dimensions of the water heating pipes.

[0052] The upper part of the wiring box 1 is equipped with several control buttons and corresponding indicator lights. The control buttons are, in order, a pneumatic control switch, a liquid replenishment switch, a liquid inlet switch, an exhaust switch, and a circulation pump 12 switch. The pneumatic control switch controls the pneumatic control valve 33, the liquid replenishment switch controls the water pump 34, the liquid inlet switch manages the liquid inlet solenoid valve 22 and the liquid inlet solenoid valve 24, the exhaust switch manages the exhaust solenoid valve 16 and the exhaust solenoid valve 29, and the pump switch is used to control the operating status of the circulation pump 12.

[0053] The main pipeline 13 is equipped with a removable filter valve 37, which is used to filter impurities and dirt in the pipeline. The filter valve 37 can also be disassembled and cleaned periodically.

[0054] The working process of this utility model includes the following steps:

[0055] Step 1: Air venting. Open the air venting control valve 16 and the air venting control valve 29, and start the circulation pump 12. This allows the water in the water storage tank 10 to enter the water heating pipe through the air venting pipe 15, while the air in the water heating pipe is vented into the water storage tank 10 through the conduit 26 and then flows into the outside environment.

[0056] Step 2: Water intake. Close exhaust valve 16 and exhaust valve 19, and open inlet valve 22 and inlet valve 24. Circulation pump 12 draws liquid from the water heating pipes and enters the water storage tank 10 through connecting pipe 20, initiating the circulation process. Simultaneously, the drainage pipe 25 creates a vortex siphon effect. Furthermore, due to the negative pressure in the water storage tank 10 and the water level being higher than the height of the cylinder 27, water in the water storage tank 10 enters the conduit 26.

[0057] Step 3: Threading the wire. Introduce one end of the wire into the threading conduit 11. The wire flows with the water in the threading conduit 26, enters the water heating pipe, and finally exits from the other end to complete the threading.

[0058] Step 4: After completing the wiring in the area, close the gas control valve 33 to prevent water from flowing out of the water tank 10 through the wiring conduit 26. Then disconnect the connection between the wiring conduit 26 and one end of the water heating pipe, as well as the connection between the connecting pipe 20 and the other end of the water heating pipe. Move the wiring box 1 to prepare for the wiring work in the next area. In addition, use the water pump 34 to continuously inject water from the water bucket into the water tank 10 to ensure a stable water level.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

[0060] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
