Description

Technical Field

[0001] This invention relates to an intelligent antifreeze system, belonging to the field of antifreeze technology, for outdoor use and for faucets and pipes requiring antifreeze, and is widely used in factories, farms, rural water houses, rural toilets, public toilets, public water supply networks and other fields. Background Technology

[0002] When temperatures are very low, faucets and pipes may freeze or even crack, severely affecting normal water use. In practice, effective protective measures are often lacking. Common methods include wrapping faucets in blankets or using electric heating tape for warmth, but these are cumbersome, wasteful of resources, and not very effective at preventing cold.

[0003] By utilizing an intelligent single-chip microcomputer temperature detection and control system, the operation of corresponding equipment is controlled according to changes in ambient temperature to achieve the purpose of antifreeze, effectively solving the above problems. Summary of the Invention

[0004] In view of this, the present invention provides an intelligent antifreeze system with simple structure, high degree of intelligence, good performance, wide range of applications, environmental protection and energy saving, and simple and easy modification of existing equipment.

[0005] The present invention solves the above-mentioned technical problems through the following technical means:

[0006] The present invention discloses an intelligent antifreeze system, comprising a power supply and a microcontroller. The microcontroller is equipped with a temperature detection switch. A main valve is installed on a main pipeline. The main pipeline is connected to at least one branch pipe. A solenoid valve is installed on each branch pipe. A water outlet button is installed at the outlet of each branch pipe. The branch pipe is connected to a drain pipe. A water pump and a first solenoid valve are installed on the drain pipe. A time relay is installed on both the water pump and the first solenoid valve. The temperature detection switch is connected to a delay switch. The pump, the first solenoid valve, and the main valve are all connected to the delay switch. The power supply provides power to the temperature detection switch, the water outlet button, the solenoid valve, the time relay, the pump, the first solenoid valve, the main valve, and the delay switch.

[0007] The time relay controls the pump and the first solenoid valve.

[0008] The power supply is a 220V AC or 12V DC power supply.

[0009] The water outlet button is equipped with a dual-reset switch.

[0010] The pump can also be replaced by a vacuum pump, which is connected to the buffer tank. The buffer tank is connected to the drain pipe, and an automatic check valve is installed at the bottom of the buffer tank.

[0011] To prevent faucets and pipes from freezing in frigid environments, effective protective measures must be taken during application. This invention is an intelligent anti-freeze system that primarily uses a microcontroller-based temperature sensor to detect the ambient temperature. When the temperature drops below a set level, a signal is transmitted to the control system, which then activates the main valve, venting system, and air supply system to drain excess water from the pipes, effectively solving the winter freezing problem. When water supply is needed, the main valve reopens. After use, the system automatically repeats the above actions within a set time, thus achieving the anti-freeze purpose.

[0012] This patent has the following advantages:

[0013] (1) An intelligent temperature control system is adopted;

[0014] (2) The present invention uses a water drainage method. When the ambient temperature is close to the freezing point, the water stored in the pipes and above the ground is drained through an automatic control system to prevent freezing.

[0015] (3) A settable time relay system is used to delay the start of the equipment;

[0016] This patented system can be used for one or more water pipe outlets.

[0017] This patent is primarily designed to prevent freezing of faucets, pipes, and related equipment.

[0018] This patent mainly utilizes an intelligent single-chip microcomputer temperature detection and control system to control the operation of corresponding equipment according to changes in ambient temperature, thereby achieving the purpose of antifreeze.

[0019] The beneficial effects of this invention are: simple structure, high degree of intelligence, good performance, wide range of applications, environmental protection and energy saving, and simple and easy modification of existing equipment. Attached Figure Description

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments: An intelligent antifreeze system of this embodiment includes a power supply 1 and a microcontroller 14. The microcontroller 14 is equipped with a temperature detection switch 2. A main valve 9 is installed on a main pipe 15. The main pipe 15 is connected to at least one branch pipe 16. A solenoid valve 4 is installed on the branch pipe 16. A water outlet button 3 is installed at the outlet of the branch pipe 16. The branch pipe 16 is connected to a drain pipe 6. A water pump 7 and a first solenoid valve 8 are installed on the drain pipe 6. A time relay 5 is installed on both the water pump 7 and the first solenoid valve 8. The temperature detection switch 2 is connected to a delay switch 10. The pump 7, the first solenoid valve 8 and the main valve 9 are all connected to the delay switch 10. The power supply 1 supplies power to the temperature detection switch 2, the water outlet button 3, the solenoid valve 4, the time relay 5, the pump 7, the first solenoid valve 8, the main valve 9 and the delay switch 10.

[0024] Time relay 5 controls pump 7 and first solenoid valve 8.

[0025] Power supply 1 is a 220V power supply.

[0026] The water outlet button 3 is equipped with a dual-reset switch.

[0027] Pump 7 can also be replaced by vacuum pump 11. Vacuum pump 11 is connected to buffer water tank 12. Buffer water tank 12 is connected to drain pipe 6. Automatic check valve 13 is installed at the bottom of buffer water tank 12.

[0028] Example 1

[0029] This patent includes a power supply 1 and a microcontroller 14. The microcontroller 14 is equipped with a temperature detection switch 2. A main valve 9 is installed on the main pipe 15. The main pipe 15 is connected to at least one branch pipe 16. A solenoid valve 4 is installed on the branch pipe 16. A water outlet button 3 is installed at the outlet of the branch pipe 16. The branch pipe 16 is connected to a drain pipe 6. A water pump 7 and a first solenoid valve 8 are installed on the drain pipe 6. A time relay 5 is installed on both the water pump 7 and the first solenoid valve 8. The temperature detection switch 2 is connected to a delay switch 10. The pump 7, the first solenoid valve 8, and the main valve 9 are all connected to the delay switch 10. The power supply 1 supplies power to the temperature detection switch 2, the water outlet button 3, the solenoid valve 4, the time relay 5, the pump 7, the first solenoid valve 8, the main valve 9, and the delay switch 10.

[0030] Time relay 5 controls pump 7 and first solenoid valve 8.

[0031] Power supply 1 is a 220V power supply.

[0032] The water outlet button 3 is equipped with a dual-reset switch.

[0033] like Figure 1As shown, this embodiment 1 uses a single-chip microcomputer digital temperature detection and control module (the anti-freeze system is activated when the temperature drops to a certain value. For example, the set temperature is 1℃, meaning the system is in working condition when the temperature is below 1℃); a time relay module, a small water pump, a solenoid valve, a self-resetting dual-channel switch, and other equipment. The time relay module controls the small water pump and the solenoid valve, and the water pump is connected to the branch pipeline through the solenoid valve.

[0034] Working principle: When the ambient temperature is higher than 1℃ (adjustable), the microcontroller's digital temperature detection and temperature control module relay is disconnected, and the antifreeze system is turned off. When the ambient temperature is lower than 1℃, the microcontroller's temperature control module relay is turned on, the antifreeze system is activated, the main solenoid valve is closed, the solenoid valve connected to the water pump is opened, the water pump is turned on, and the remaining water in the pipeline is pumped out, achieving the purpose of antifreeze.

[0035] This system features a time-delay function. In multi-supply applications, if multiple users utilize the system sequentially within a short period, the anti-freeze system doesn't need to be activated immediately after the first user finishes. Instead, it activates after a set time (3-10 minutes), during which freezing is generally unlikely. During use, pressing the flush button (self-resetting dual-way switch) disconnects the anti-freeze system circuit, putting it in a resting state. The solenoid valve then conducts, allowing water to flow normally. When the flush button resets, the solenoid valve disengages, and the anti-freeze system circuit reconnects. The anti-freeze system then activates after the set time delay (e.g., in public restrooms where multiple users utilize the system sequentially; the delay time is extended sequentially for the second, third, and subsequent users until the set time is reached). This system can be controlled via jumpers for one or more water outlets.

[0036] Example 2

[0037] The system includes a power supply 1 and a microcontroller 14. The microcontroller 14 is equipped with a temperature detection switch 2. A main valve 9 is installed on the main pipe 15. The main pipe 15 is connected to at least one branch pipe 16. A solenoid valve 4 is installed on the branch pipe 16. A water outlet button 3 is installed at the outlet of the branch pipe 16. The branch pipe 16 is connected to a drain pipe 6. A water pump 7 and a first solenoid valve 8 are installed on the drain pipe 6. A time relay 5 is installed on both the water pump 7 and the first solenoid valve 8. The temperature detection switch 2 is connected to a delay switch 10. The pump 7, the first solenoid valve 8, and the main valve 9 are all connected to the delay switch 10. The power supply 1 supplies power to the temperature detection switch 2, the water outlet button 3, the solenoid valve 4, the time relay 5, the pump 7, the first solenoid valve 8, the main valve 9, and the delay switch 10.

[0038] Time relay 5 controls pump 7 and first solenoid valve 8.

[0039] Power supply 1 is a 220V power supply.

[0040] The water outlet button 3 is equipped with a dual-reset switch.

[0041] Pump 7 can also be replaced by vacuum pump 11. Vacuum pump 11 is connected to buffer water tank 12. Buffer water tank 12 is connected to drain pipe 6. Automatic check valve 13 is installed at the bottom of buffer water tank 12.

[0042] like Figure 2 As shown, this patent employs a single-chip microcomputer-based digital temperature detection and control module (the anti-freeze system activates when the temperature drops to a certain value. For example, the set temperature is 1℃, meaning the system operates below 1℃); a time relay module; a small air pump; a buffer water tank; an automatic check valve; a solenoid valve; and a self-resetting dual-way switch. The time relay module controls the air pump and solenoid valve. The air pump is installed above the buffer water tank, and the automatic check valve is installed below the buffer water tank, connected to the branch pipeline via the solenoid valve.

[0043] Working principle: When the ambient temperature is above 1℃ (adjustable), the microcontroller's digital temperature detection and control module relay disconnects, and the antifreeze system shuts down. When the ambient temperature is below 1℃, the microcontroller's temperature control module relay turns on, the antifreeze system starts, the main solenoid valve closes, the solenoid valves connected to the branch pipes open, the air pump starts, and the automatic check valve locks under negative pressure, drawing residual water from the pipes into the buffer tank. When the air pump stops running, the air pressure inside and outside the buffer tank equalizes, the automatic check valve opens, and the water in the buffer tank is automatically discharged, achieving the purpose of antifreeze.

[0044] Example 1 and Example 2 have the same other functions. The difference is that in Example 1, the water pump and the main water pipe (usually below the frost layer) are on the same plane, and a small well needs to be built for installation and maintenance; in Example 2, no small well is needed, and only a solenoid valve and a pipe need to be installed and buried. Users can choose to use according to different situations.

[0045] like Figure 3 As shown,

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
