Description

Technical Field

[0001] The utility model provides an antifreeze device for building water supply and drainage, belonging to the technical field of antifreeze for water supply and drainage. Background Art

[0002] In cold regions or cold seasons, the water supply and drainage systems of buildings face the serious problem of ice blockage. When the water temperature in the water pipe drops below freezing, the water will freeze and expand, causing the pipe to rupture or blockage, the water supply and drainage system cannot operate normally, and even cause water damage inside the building.

[0003] Antifreeze measures for building water supply and drainage usually include adding insulation cotton, setting up insulation layers and other material insulation methods. However, when the temperature is too low, the material insulation method cannot prevent the drainage pipes from freezing. At this time, people often convert electrical energy into thermal energy by heating, and then transfer the heat to the pipes to avoid freezing. The method of using thermal energy to prevent freezing is effective, but the energy consumption is large and it is inconvenient to use it continuously in actual work. When the temperature gradually rises, it should be stopped immediately and the performance of the material itself should be used for insulation. The existing technology is not convenient to freely convert the two antifreeze methods according to the actual situation. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing antifreeze device for building water supply and drainage is inconvenient to freely convert between the material insulation mode and the thermal energy insulation mode according to actual conditions.

[0005] In order to solve the above problems, the utility model proposes a technical solution: an antifreeze device for building water supply and drainage, comprising a water inlet pipe, an antifreeze pipe and a drain pipe are fixedly connected in sequence on one side of the water inlet pipe, and the water inlet pipe, the antifreeze pipe and the drain pipe are connected in sequence; a separator pipe is fixedly arranged inside the antifreeze pipe, and there is a gap between the separator pipe and the antifreeze pipe, and the gap is an antifreeze air layer; the water inlet pipe is connected with the separator pipe and the drain pipe in sequence; an inlet pipe is arranged on the separator pipe, and the inlet pipe connects the inside of the separator pipe with the antifreeze air layer; a heating resistor is arranged on the inner wall of the antifreeze pipe; an outlet pipe is arranged on the wall of the antifreeze pipe, a water receiving box is fixedly arranged below the antifreeze pipe, and the outlet pipe is connected with the water receiving box.

[0006] As an improvement, an electric control valve is provided in the inlet pipe, and an electric control valve is also provided in the outlet pipe; and a control module connected to two sets of electric control valve circuits is provided on the outer wall of the antifreeze pipe.

[0007] As an improvement, a water temperature sensor is provided in the antifreeze air layer, and an air temperature sensor is provided outside the antifreeze pipe; the water temperature sensor and the air temperature sensor are both connected to the control module circuit.

[0008] As an improvement, a reflux pump is provided in the water receiving box, a working end of the reflux pump is connected to a reflux pipe, and the reflux pipe is communicated with the drain pipe.

[0009] As an improvement, the outer wall of the antifreeze pipe is provided with a power supply device capable of providing power to the electric control valve, the water temperature sensor, the air temperature sensor, the heating resistor, and the reflux pump.

[0010] As an improvement, a heat-insulating layer is embedded inside the antifreeze pipe wall.

[0011] Beneficial effects of the utility model:

[0012] A separator tube is fixedly arranged inside the antifreeze pipe, and there is a gap between the separator tube and the antifreeze pipe, and the gap is an antifreeze air layer; by setting the separator tube, an antifreeze air layer can be formed; in this way, the antifreeze pipe actually forms a double-tube structure, and the double-tube structure has good thermal insulation and antifreeze performance; at the same time, an inlet pipe is arranged on the separator tube, and an outlet pipe is arranged on the wall of the antifreeze pipe; when the temperature is too low, the inlet pipe can introduce the water in the separator tube into the antifreeze air layer, and use the heating resistor to heat the water in the antifreeze air layer, so as to facilitate thermal insulation; and when the temperature rises, the water in the antifreeze air layer is discharged through the outlet pipe, so as to facilitate material insulation and energy saving. Therefore, by setting a double-layer antifreeze pipe, the present application can not only use the antifreeze air layer formed by the double-layer gap for thermal insulation and antifreeze, but also introduce water into the antifreeze air layer, and use heat energy to prevent the pipe from freezing, thereby realizing free conversion between the material insulation method and the thermal insulation method, which can not only achieve good thermal insulation and antifreeze effects, but also save energy.

[0020] By setting up a double-layer antifreeze pipe 2, it is possible to use the antifreeze air layer 8 formed by the double-layer gap to keep warm and prevent freezing, and water can be introduced into the antifreeze air layer 8 to use heat energy to prevent the pipe from freezing, thereby realizing free conversion between material insulation method and thermal energy insulation method, which can achieve good insulation and antifreeze effect and save energy.

[0026] Principle of the utility model

[0027] When the water supply and drainage pipes 3 work normally, water enters the partition pipe 9 in the antifreeze pipe 2 from the water inlet pipe 1, then enters the drainage pipe 3 from the partition pipe 9, and finally is discharged from the drainage pipe 3; at this time, there is only air in the antifreeze air layer 8. Since the thermal conductivity of air is much lower than that of solids and liquids, the existence of the antifreeze air layer 8 can play a good antifreeze effect. At this time, the entire antifreeze device is in a material antifreeze state. The air temperature sensor 15 can monitor the outside air temperature. When the outside air temperature is detected to be lower than the set value, the air temperature sensor 15 sends a signal to the control module 6, and the control module 6 opens the electric control valve of the inlet pipe 10, and the water flows through the inlet pipe 10 into the antifreeze air layer 8 and fills it. At the same time, the control module 6 controls the heating resistor 11 to work, heats the water in the antifreeze air layer 8, and the heated water is on the outer wall of the partition tube 9, which can transfer heat to the inside of the partition tube 9 through the partition tube 9, thereby avoiding ice formation inside the partition tube 9; the water temperature sensor 12 can monitor the water temperature in the antifreeze air layer 8 in real time. At this time, the entire antifreeze device is in a state of thermal energy antifreeze.

[0028] When the temperature sensor 15 detects that the outside temperature is higher than the set value, the control module 6 controls the heating resistor 11 to stop working; at the same time, the electric control valve on the outlet pipe 13 is opened, and the water in the antifreeze air layer 8 flows into the water receiving box 4 through the outlet pipe 13. At this time, there is only air in the antifreeze air layer 8, and the entire antifreeze device returns to the material antifreeze state. Therefore, by setting a double-layer antifreeze pipe 2, the present application can not only use the antifreeze air layer 8 formed by the double-layer gap for heat preservation and antifreeze, but also can guide water into the antifreeze air layer 8, and use heat energy to prevent the pipe from freezing, thereby realizing free conversion between the material insulation method and the heat energy insulation method, which can not only achieve a good insulation and antifreeze effect, but also save energy.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
