[0026] Embodiment

[0027] Reference Figs. 1-3 For an embodiment of the utility model, provide a kind of building design drainage pipe with freeze-proof device, it include: support unit 100 and freeze-proof unit 200;

[0028] Wherein, support unit 100 includes heat preservation pipe 101 and two arc-shaped boxes 102 fixedly connected on the inner wall of heat preservation pipe 101, the inner cavity of heat preservation pipe 101 is provided with drain pipe 103, two arc-shaped boxes 102 are rotationally symmetrical and fixedly connected on the outer wall of drain pipe 103, the inner wall of heat preservation pipe 101 is fixedly connected with annular box 104, drain pipe 103 passes through annular box 104 and is fixedly connected with annular box 104;

[0029] Freeze-proof unit 200 includes water supply pipe 201 and L-shaped pipe 202 fixedly connected on the outer wall of heat preservation pipe 101, one end of L-shaped pipe 202 is communicated with water supply pipe 201, one end of water supply pipe 201 penetrates heat preservation pipe 101 and is communicated with one of arc-shaped boxes 102, one end of L-shaped pipe 202 penetrates heat preservation pipe 101 and is communicated with the other arc-shaped box 102, the outer wall of heat preservation pipe 101 is fixedly connected with water outlet pipe 203, one end of water outlet pipe 203 penetrates heat preservation pipe 101 and is communicated with annular box 104, the pipe wall of L-shaped pipe 202 and water outlet pipe 203 is all set with valve, one side of two arc-shaped boxes 102 is all fixedly communicated with three hot water pipes 204, one end of each hot water pipe 204 is all communicated with annular box 104.

[0030] Heat preservation pipe 101 is used to heat preservation to drain pipe 103, to avoid cold air and snow water to drain pipe 103 rapid cooling, water supply pipe 201 is connected with water pump and pipeline, to deliver hot water to water supply pipe 201, by opening the valve of L-shaped pipe 202, hot water can be delivered to two arc-shaped boxes 102 respectively, the hot water in arc-shaped box 102 can flow to the direction of annular box 104 through hot water pipe 204, hot water pipe 204 has heat conductivity, so that the heat of hot water pipe 204 is transmitted to drain pipe 103 through air, to achieve the purpose of freeze-proof, the heat loss in heat preservation pipe 101 can be reduced by heat preservation pipe 101, the hot water in annular box 104 can be discharged through water outlet pipe 203, so that the flow of liquid in drain pipe 103 is not blocked, and drain pipe 103 is heated to prevent freezing;

[0031] By closing the valve of the water outlet pipe 203, hot water can be stored in the heat preservation pipe 101 to continuously heat the drain pipe 103, and when the water temperature drops, it is discharged through the water outlet pipe 203. When the liquid in the drain pipe 103 flows less, the valve of the L-shaped pipe 202 is closed, and the water pressure of the water supply pipe 201 is reduced, so that the hot water is only delivered to the arc-shaped box 102 connected by the water supply pipe 201. Thus, the three hot water pipes 204 at the bottom can concentrate on heating the bottom of the drain pipe 103, while ensuring the anti-freezing effect, and reducing the use of hot water.

[0032] In addition, the inner wall of the heat preservation pipe 101 is fixedly connected with a fixed disc 105, and a plurality of through holes 106 matching the hot water pipes 204 are formed in one side of the fixed disc 105. Each hot water pipe 204 passes through the through hole 106 of the fixed disc 105.

[0033] When the length of the hot water pipe 204 is longer, a corresponding number of fixed discs 105 are installed in the heat preservation pipe 101, and the fixed disc 105 is used to support the hot water pipe 204 to reduce the deformation of the hot water pipe 204 due to gravity.

[0034] Further, the pipe wall of each hot water pipe 204 is fixedly sleeved with a plurality of heat conducting blocks 205, one side of each heat conducting block 205 is fixedly connected with a heat conducting sheet 206, and the heat conducting sheet 206 is arc-shaped. Each heat conducting sheet 206 is fixedly connected to the outer wall of the drain pipe 103.

[0035] The heat conducting block 205 and the heat conducting sheet 206 are made of copper, iron and other materials with heat conductivity. The heat of the hot water pipe 204 is transmitted to the heat conducting sheet 206 through the heat conducting block 205. The curvature of the heat conducting sheet 206 matches the outer wall of the drain pipe 103. The heat of the hot water pipe 204 can be directly transmitted to the outer wall of the drain pipe 103 through the heat conducting sheet 206 to improve the heating effect.

[0036] Specifically, the outer wall of the heat preservation pipe 101 is fixedly connected with a temperature sensor 207 penetrating the heat preservation pipe 101, and the temperature sensor 207 is located close to one end of the annular box 104 connected to the heat preservation pipe 101.

[0037] The temperature sensor 207 refers to a sensor that can sense temperature and convert it into an output signal. The measurement probe of the temperature sensor 207 is located in the heat preservation pipe 101. The temperature sensor 207 is used to measure the temperature inside the heat preservation pipe 101 to heat the drain pipe 103 to achieve the purpose of anti-freezing. When hot water flows in the heat preservation pipe 101, due to heat loss, the temperature at the position of the annular box 104 is lower than that at the position of the arc-shaped box 102. The temperature sensor 207 is used to detect the temperature around the annular box 104 to determine the lowest temperature inside the heat preservation pipe 101, so that the user can adjust the temperature and amount of hot water according to the temperature.

[0038] Further, the outer wall of the heat preservation pipe 101 is fixedly connected with a pressure relief pipe 208, and the end of the pressure relief pipe 208 is fixedly connected with an automatic exhaust valve 209.

[0039] When the temperature inside the heat preservation pipe 101 increases, the pressure inside the heat preservation pipe 101 increases, and when the pressure inside the heat preservation pipe 101 increases to a certain amount, the hot air can be discharged through the automatic exhaust valve 209 at the top of the pressure relief pipe 208 to complete automatic pressure relief and reduce the risk of expansion due to the increase in the pressure inside the heat preservation pipe 101.

[0040] During use, the water pump and pipeline are connected to the water supply pipe 201, and the valve of the L-shaped pipe 202 is opened to deliver hot water into the two arc-shaped boxes 102, and the hot water in the arc-shaped boxes 102 can flow to the direction of the annular box 104 through the hot water pipes 204, and the heat of the hot water pipes 204 is transmitted to the outer wall of the drain pipe 103 through the air to achieve the purpose of anti-freezing, and the heat of the hot water pipes 204 can be directly transmitted to the outer wall of the drain pipe 103 through the heat-conducting block 205 and the heat-conducting sheet 206 to improve the heating effect, and the temperature sensor 207 can detect the lowest temperature inside the heat preservation pipe 101 to allow the user to adjust the temperature and amount of hot water according to the temperature, and when the pressure inside the heat preservation pipe 101 increases, the automatic exhaust valve 209 automatically completes pressure relief, and the hot water in the annular box 104 can be discharged through the water outlet pipe 203;

[0041] By closing the valve of the water outlet pipe 203, the hot water can be stored inside the heat preservation pipe 101 to continuously heat the drain pipe 103, and when the water temperature decreases, the hot water can be discharged through the water outlet pipe 203, and when the liquid in the drain pipe 103 flows less, the valve of the L-shaped pipe 202 is closed and the water pressure of the water supply pipe 201 is reduced, so that the three hot water pipes 204 at the bottom can be used to concentrate heating on the bottom of the drain pipe 103, which not only ensures the anti-freezing effect but also reduces the use of hot water.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
