Description

Technical Field

[0001] The present application relates to the technical field of water supply equipment, and in particular to an antifreeze water supply device with liquid level control and automatic water replenishment. Background Art

[0002] Due to the high altitude, extremely cold climate, and other harsh conditions in high-altitude and cold regions, water supply systems often face the risk of freezing water supply piles and faucets. Existing frost-resistant water supply piles typically use electric heating and insulation. However, if this approach is directly driven by photovoltaics, the temperature drops rapidly at night, making it difficult to meet operational requirements. Incorporating phase change materials into the piles for heat storage or using more economical hot water storage methods can prevent freezing. However, when the heat storage materials directly utilize water, the water evaporates during the day due to the electric heating, reducing the heat storage capacity. Therefore, the frost protection function of existing water supply piles is short-lived, making it difficult to meet the demand for long-term frost-resistant water supply. Utility Model Content

[0027] Example

[0028] Reference Figure 1-Figure 3 This embodiment provides an antifreeze water supply device with liquid level control and automatic water replenishment, including a water delivery assembly 100, a heat storage tube 200, a water level sensing device 400, and a water replenishment assembly 500. The water delivery assembly 100 is used to deliver water; the heat storage tube 200 is sleeved on the water delivery assembly 100, and a sealed cavity 300 for storing water is formed between the heat storage tube 200 and the water delivery assembly 100; the water level sensing device 400 is used to sense the water level in the sealed cavity 300; and the water replenishment assembly 500 is electrically connected to the water level sensing device 400 and is used to guide water in the water delivery assembly 100 into the sealed cavity 300.

[0029] In this embodiment, when the water level sensing device 400 detects that the water level in the sealed cavity 300 is lower than the preset position, it can send a signal to the water replenishment component 500 to make it operate, thereby automatically leading the water in the water delivery component 100 into the sealed cavity 300, thereby automatically replenishing the sealed cavity 300 with water. The situation where there is no hot water stored in the heat storage pipe 200 due to high-temperature evaporation will not occur. Therefore, when there is electricity, heat can be stored through the hot water stored in the heat storage pipe 200. When there is no electricity, the hot water can release heat, which can make the water delivery component 100 less likely to be frozen, thereby extending the anti-freeze function maintenance time, achieving smooth water supply, and meeting normal use in high-altitude and cold areas.

[0030] It should be noted that the water level sensing device 400 can adopt an existing water level sensor, which can have an MCU control chip built in. When it detects that the water level is lower than a preset position, a control signal is sent to the water replenishment component 500. When the detected water level reaches the preset position, the water replenishment component 500 stops running.

[0031] As an optional embodiment, the water replenishment component 500 includes a control valve 510, a water diversion pipe 520 and a drain pipe 530. The control valve 510 is electrically connected to the water level sensing device 400, and the control valve 510 is arranged at the inner top of the sealed cavity 300; one end of the water diversion pipe 520 is connected to the control valve 510, and the other end of the water diversion pipe 520 is connected to the water delivery component 100; one end of the drain pipe 530 is connected to the control valve 510, and the other end of the drain pipe 530 is located at a preset height position in the sealed cavity 300.

[0032] In this embodiment, the control valve 510 can adopt an existing micro solenoid valve. When the water level sensing device 400 cannot detect the water level, the water level sensing device 400 can transmit a signal to the micro solenoid valve. The micro solenoid valve opens so that the water in the water delivery component 100 passes through the water diversion pipe 520 and the drainage pipe 530 in turn and enters the heat storage pipe 200. Similarly, when the water level sensing device 400 detects water, it transmits a signal to the micro solenoid valve, and the micro solenoid valve closes and no longer discharges water, thereby realizing automatic control of water replenishment without the need for manual management.

[0033] It should be noted that, since water pressure is always maintained in the water delivery component 100, opening the control valve 510 can cause the water in the water delivery component 100 to automatically flow into the water diversion pipe 520 and the drainage pipe 530, thereby achieving automatic water replenishment.

[0034] As an optional embodiment, a heating component 600 is further provided in the sealed cavity 300. The heating component 600 is used to generate heat, thereby heating the water in the heat storage tube 200 to provide antifreeze for the water delivery component 100, and will not be affected by heating evaporation. When there is no electricity, after the heating component 600 stops working, the water in the heat storage tube 200 can continue to emit heat to maintain the antifreeze function.

[0035] As an optional embodiment, the heating assembly 600 includes a heat source tube 610 and an electric heat source 620. The heat source tube 610 is used to contact the water in the sealed cavity 300; the electric heat source 620 is arranged in the heat source tube 610 and is electrically connected to the power supply.

[0036] In this embodiment, heat source pipe 610 protects electric heat source 620, which is a conventional heating cable. When powered, electric heat source 620 generates heat, thereby heating the stored water. Typically, the power source is a conventional photovoltaic panel, but other sources are also possible. Therefore, during the day, powered by the photovoltaic panel, electric heat source 620 continuously heats the stored water, maintaining the overall freeze resistance of the device. At night, both the photovoltaic panel and electric heat source 620 are deactivated, and the stored water begins to release heat, insulating the water supply device at night and preventing freezing.

[0037] As an optional embodiment, the water supply assembly 100 includes a water supply pipe 110, a switch valve 120, a rotating part 130 and a water outlet pipe 140. The bottom of the water supply pipe 110 extends out of the bottom end of the sealed cavity 300, and the water supply pipe 110 is used to transport water; the input port of the switch valve 120 is movably connected to the top of the water supply pipe 110, and the switch valve 120 is located in the sealed cavity 300; the rotating part 130 is connected to the switch valve 120, and the rotating part 130 extends out of the top of the sealed cavity 300; the water outlet pipe 140 is connected to the output port of the switch valve 120, and the water outlet pipe 140 passes through the side wall of the heat storage tube 200.

[0038] In this embodiment, when water is needed, the rotating member 130 can be manually rotated to open the on-off valve 120, and water can then flow out through the water pipe 110, the on-off valve 120, and the water outlet pipe 140 for use. Here, important water supply components such as the water pipe 110 and the on-off valve 120 are all located within the sealed cavity 300 of the heat storage tube 200 to ensure antifreeze protection. It should be noted that the on-off valve 120 can be an existing angle valve, and the inlet of the on-off valve 120 can be connected to the water pipe 110 using an existing flexible joint adapter. The rotating member 130 can be a rotary handwheel or a faucet switch.

[0039] As an optional embodiment, the water delivery assembly 100 also includes a reducer 150, which is connected to the bottom of the water delivery pipe 110. The diameter of the reducer 150 is larger than the diameter of the water delivery pipe 110, and the water delivery pipe 110 extends out of the bottom end of the sealed cavity 300 through the reducer 150.

[0040] In this embodiment, since the diameter of the water supply pipe 110 is generally small and it is not easy to seal with the bottom end of the sealed cavity 300, a reducer 150 is provided here to be connected to the water supply pipe 110. When the reducer 150 with a larger diameter extends out of the bottom end of the sealed cavity 300 and is connected to the water source, it is convenient to set a sealing structure to ensure the sealing, thereby reducing the heat loss of the sealed cavity 300.

[0041] As an optional embodiment, the reducer 150 includes a connecting pipe 151, two reducing connectors 152 and a water inlet pipe 153. The diameter of the connecting pipe 151 is larger than the diameter of the water supply pipe 110; one end of the connecting pipe 151 located in the sealed cavity 300 is connected to the water supply pipe 110 through one of the reducing connectors 152, and the end of the connecting pipe 151 extending out of the sealed cavity 300 is connected to the other reducing connector 152; the water inlet pipe 153 is connected to the connecting pipe 151 through the reducing connector 152.

[0042] In this embodiment, the reducer 150 is split into a combined structure of a connecting pipe 151, two reducer connectors 152, and a water inlet pipe 153. The water inlet pipe 153 is used to connect to a water source, thereby forming a split structure that is easy to assemble (can be connected by threading), reducing the difficulty of pipe manufacturing. The diameter of the water inlet pipe 153 is generally the same as the diameter of the water pipe 110. It should be noted that since the general reducer connector 152 model cannot be directly converted to the model of the water pipe 110, the upper and lower ends are reduced in diameter. Here, the bottom of the water pipe 110 can also be reduced in diameter according to the actual size, so there is no need to provide a reducer connector 152.

[0043] As an optional embodiment, an electric fusion connection sleeve 700 is provided at the bottom of the heat storage tube 200. The bottom of the electric fusion connection sleeve 700 is sleeved on the outer wall of the connecting tube 151. The entire reducer 150 can be fixed by electric fusion welding through the electric fusion connection sleeve 700, and finally an integrated structure is formed, which is not easy to loosen, thereby ensuring the sealing of the sealing cavity 300, that is, ensuring the thermal insulation effect.

[0044] As an optional embodiment, it also includes an insulation component 800, which includes an outer shell 810 and an insulation material 820. The heat storage pipe 200 and the water outlet pipe 140 are both located in the outer shell 810, and the bottom of the outer shell 810 is sleeved on the outer wall of the electric fusion connection sleeve 700, and the rotating part 130 extends out of the top of the outer shell 810; the insulation material 820 is filled in the outer shell 810, and the insulation material 820 simultaneously covers the heat storage pipe 200 and the water outlet pipe 140.

[0045] In this embodiment, the outer shell 810 plays a protective role and can be made of high-hardness, corrosion-resistant materials, such as stainless steel, surface-treated carbon steel, etc.; the thermal insulation material 820 plays a role in insulating the water delivery component 100, further improving the anti-freeze effect. Here, the thermal insulation material 820 can be made of polyurethane thermal insulation cotton with strong thermal insulation performance and can be filled.

[0046] As an optional embodiment, the top of the outer shell 810 is detachably connected to a cover 830, and the rotating member 130 is movable through the cover 830. The cover 830 can be detachably connected via bolts, facilitating assembly and subsequent disassembly for internal inspection. Here, the cover 830 is also composed of a shell and an insulating material 820 filled inside. A sealing bushing is provided between the rotating member 130 and the cover 830, and a sealing gasket is provided between the insulating material 820 in the cover 830 and the insulating material 820 in the outer shell 810. This can further improve the sealing performance, reduce heat loss in the heat storage tube 200, and better ensure that the water delivery assembly 100 will not freeze.

[0047] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
