Description

Technical Field

[0001] The present invention relates to the technical field of water conveyance pipelines, and in particular to an anti-freezing pipeline water conveyance structure. Background Art

[0002] In cold regions such as Tibetan areas, the freezing and cracking of water pipes is a common and troublesome problem. When the temperature drops below the freezing point, the water in the water pipe freezes. After the water freezes, its volume expands, thus generating a huge pressure on the water pipe, and finally causing the water pipe to burst. The freezing and cracking of water pipes not only cause waste of water resources, but also may damage the surrounding environment and facilities, such as flooding houses and damaging furniture. In addition, repairing frozen and cracked water pipes also requires a lot of time and money.

[0003] Traditional anti-freezing methods, such as insulating and wrapping the water pipes, although to a certain extent can slow down the cooling rate of the water in the water pipe, still it is difficult to completely avoid the problem of water pipe freezing and cracking under extremely cold weather conditions. Moreover, for some water pipes exposed outdoors or buried in relatively shallow soil layers (frost layers), the effect of insulation measures is often limited. Therefore, a more effective anti-freezing pipeline water conveyance structure is needed to solve the problem of water pipe freezing and cracking in cold regions. Summary of the Invention

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0042] Refer to Figures 1-6 , an anti-freezing pipeline water conveyance structure, including an outer rotating adapter 1 and an inner rotating adapter 7 located inside the outer rotating adapter 1 that can rotate around the central shaft. The circumferential outer wall of the outer rotating adapter 1 is provided with a first adapter 2, a second adapter 3, and a third adapter 4 distributed in a T shape. The other end of the first adapter 2 is connected to a tap pipeline 5, and the other end of the third adapter 4 is connected to a water supply pipeline 6. The circumferential outer wall of the inner rotating adapter 7 is provided with three docking pipes 8 distributed in a T shape, and the docking pipes 8 can be connected to the first adapter 2, the second adapter 3, or the third adapter 4;

[0043] During use, install this pipeline structure at a position below the frozen soil layer. Users can rotate the inner rotating adapter 7 at night so that two docking pipes 8 are respectively docked with the first adapter 2 and the second adapter 3 (as Figure 4) At this time, the water in the faucet pipe 5 can enter the second pipe 3 through the inner rotating adapter 7 and be discharged, realizing the emptying of the water in the faucet pipe 5, thus preventing the faucet pipe 5 above the frozen soil layer from freezing at night. When water is needed, just reset the inner rotating adapter 7 so that the two docking pipes 8 are respectively docked with the first pipe 2 and the third pipe 4 (as Figure 3 ) At this time, after the faucet is opened, the water in the water supply pipe 6 can enter the faucet pipe 5 through the inner rotating adapter 7 for normal water use.

[0044] Among them, the inner rotating adapter 7 is rotatably connected to the outer rotating adapter 1 through the central axis 11 at the rear. A fixed seat 9 is fixedly connected to the rear of the outer rotating adapter 1. A rotating shaft 10 is rotatably connected to the fixed seat 9. The adjacent ends of the rotating shaft 10 and the central axis 11 are respectively fixedly sleeved with a second bevel gear 13 and a first bevel gear 12, and the second bevel gear 13 and the first bevel gear 12 are meshed and connected;

[0045] During use, place the top of the rotating shaft 10 above the ground surface. At this time, the second bevel gear 13 can be driven to rotate by rotating the rotating shaft 10, and then the second bevel gear 13 meshes with the first bevel gear 12 to drive the central axis 11 and the inner rotating adapter 7 to rotate, so as to realize the switching of the docking state of the inner rotating adapter 7.

[0046] Furthermore, two positioning columns 21 for blocking the docking pipe 8 are fixedly connected inside the outer rotating adapter 1 and are located in the third quadrant;

[0047] During use, when the inner rotating adapter 7 rotates to the correct docking state, it will be blocked by one of the positioning columns 21 and cannot continue to rotate, indicating that the accurate docking position has been reached at this time, which is convenient for use.

[0048] Furthermore, a water storage tank 14 is arranged below the outer rotating adapter 1. A water tank inlet pipe 15 is provided at the top of the water storage tank 14. The water tank inlet pipe 15 is connected to the third pipe 4. A water pump 16 is fixedly connected inside the water storage tank 14. The water outlet end of the water pump 16 is connected to a return pipe 17. The other end of the return pipe 17 passes through the water storage tank 14 and is connected to the water supply pipe 6. A one-way valve 18 is installed on the return pipe 17;

[0049] During use, the emptied water can be collected into the water storage tank 14 through the water tank inlet pipe 15. When the user opens the faucet to use water, the water pump 16 will start, and the water in the water storage tank 14 will be pumped into the water supply pipe 6 through the return pipe 17, preferentially using the stored water in the water storage tank 14, thus avoiding waste of water resources.

[0050] In another embodiment, an anti-freezing pipeline water conveyance structure further includes a water level acquisition module 19, a water pressure acquisition module 20, an electric current acquisition module 22, and a central processor. The water level acquisition module 19 is installed inside the water storage tank 14 and is used to monitor the water storage volume in the water storage tank 14 in real time and generate a water level change coefficient through the central processor;

[0051] The water pressure acquisition module 20 is installed on the water supply pipeline 6 and is used to detect the pressure change in the water supply pipeline 6 in real time when the faucet is opened;

[0052] The electric current acquisition module 22 is installed on the water pump 16 and is used to monitor the actual output current of the water pump 16 during operation in real time and generate an electric current fluctuation coefficient through the central processor;

[0053] It should be noted that the water level acquisition module 19 can be a liquid level sensor or other devices that can monitor the water storage volume in the water storage tank 14 in real time. The water pressure acquisition module 20 can be a water pressure sensor or other devices that can detect the pressure change in the water supply pipeline 6 in real time when the faucet is opened. The electric current acquisition module 22 can be an electric current sensor or other devices that can monitor the actual output current of the water pump 16 during operation in real time. The central processor is integrated in the waterproof control box and installed in the ground area above the frozen soil layer and close to the water storage tank. It integrates a data fusion algorithm. Therefore, the water level acquisition module 19, the water pressure acquisition module 20, and the electric current acquisition module 22 are not specifically limited here and can be selected according to actual needs;

[0054] During use, the central processor comprehensively analyzes the generated water level change coefficient and electric current fluctuation coefficient, generates an evaluation coefficient, determines whether the current water supply state is stable, compares the evaluation coefficient with a preset evaluation coefficient reference threshold, and controls the working state of the water pump 16 according to the comparison result.

[0055] Among them, the output end and input end of the water level acquisition module 19, the output end and input end of the water pressure acquisition module 20, and the output end and input end of the electric current acquisition module 22 are electrically connected to the input end and output end of the central processor respectively, and the output end of the central processor is electrically connected to the input end of the water pump 16.

[0056] In another embodiment, through the cooperation of the water level acquisition module 19, the water pressure acquisition module 20, the electric current acquisition module 22, and the central processor, the central processor comprehensively analyzes the generated water level change coefficient and electric current fluctuation coefficient, generates an evaluation coefficient, determines whether the current water supply state is stable, compares the evaluation coefficient with a preset evaluation coefficient reference threshold, and controls the working state of the water pump 16 according to the comparison result. The specific implementation steps are as follows:

[0059] Coefficient calculation: The central processing unit calculates the water level change coefficient, the current fluctuation coefficient and the evaluation coefficient;

[0060] Among them, the current fluctuation coefficient reflects the difference between the actual output current of the water pump 16 when pumping water from the water storage tank 14 at the initial moment within T time and the actual output current of the water pump 16 when pumping water from the water storage tank 14 at different moments. If the value of I σ is small, it indicates that the water pump runs smoothly; if the value of I σ is large, it may be due to pipeline blockage, motor aging or unstable voltage resulting in abnormal load;

[0061] The generation logic of the current fluctuation coefficient is:

[0062] S1. Obtain the actual output current of the water pump 16 at different moments within T time when the water pump 16 pumps water from the water storage tank 14 through the current acquisition module 22, and calibrate the actual output current obtained at the nth moment within T time as

[0064]

[0065] In the formula, is the average current within T time; k is the number of pressure sampling times within T time.

[0066] Among them, the water level change coefficient reflects the difference between the actual water storage volume in the water storage tank 14 when the water pump 16 pumps water from the water storage tank 14 at the initial moment within T time and the actual water storage volume in the water storage tank 14 when the water pump 16 pumps water from the water storage tank 14 at different moments. If the value of L Δ is small (the water level fluctuates gently), it indicates that the water supply of the water storage tank 14 is stable and there is no need to frequently adjust the power of the water pump 16; if the value of L Δ is large (the water level fluctuates violently), then it is necessary to adjust the power of the water pump 16;

[0067] The generation logic of the water level change coefficient is:

[0068] S1. Obtain the actual water storage volume in the water storage tank 14 at different moments within time T when the water pump 16 pumps water from the water storage tank 14 through the water level acquisition module 19, and calibrate the actual water storage volume obtained at the m-th moment within time T as

[0069] S2. Calculate the residual density coefficient, and the calculation expression is:

[0070] In the formula, t is the number of sampling times within time T.

[0071] Among them, through the central processing unit for formula analysis, according to the formula:

[0072]

[0073] In the formula, C pg is the evaluation coefficient, r1 and r2 are the preset weight coefficients of water level and current, and r1, r2 > 0.

[0074] Dynamic adjustment: If the water pressure acquisition module 20 detects that the faucet is opened and ΔP ≥ P threshold and L tank ≥ L min , start the water pump 16. If C pg < C op : Maintain the current parameters of the water pump 16; if C pg ≥ C op : Then increase the power of the water pump 16;

[0075] In the above, L tank is the actual water storage volume in the water storage tank 14, and ΔP is the instantaneous pressure change detected by the water pressure acquisition module 20.
