Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an anti-freezing cracking mechanism and a water pump body thereof. Background Art

[0002] Water pumps are used to transport liquids and have a wide range of applications. When water pumps are used in low temperatures in winter, the water may freeze due to the low temperature. After the water freezes, its volume increases, which squeezes the pump body and eventually causes the pump body to crack, causing damage to the water pump. Therefore, it is very important to take measures to prevent the water pump from freezing and cracking in low temperatures in winter. The traditional way is to wrap the outside of the water pump body with a quilt or blanket. However, in a low temperature environment, the quilt or blanket cannot generate heat. As the low-temperature water flows, it will carry the low temperature of the external environment into the water pump. Under the wrapping effect of the quilt or blanket, the inside is always in a low-temperature state, which will still cause the water to freeze. Utility Model Content

[0024] Heating wire 2, heating wire 2 is used to provide heat;

[0025] The wrapping sleeve 1 is used for installing the heating wire 2, and the heating wire 2 is arranged inside the wrapping sleeve 1;

[0026] The thermal insulation layer 6 is used to prevent the heat generated by the heating wire 2 from escaping;

[0027] The ventilation holes 7 are used to transmit the heat generated by the heating wire 2. The ventilation holes 7 are provided on the inner wall of the wrapping sleeve 1.

[0028] The mounting member 5 is used for fixing and installing the wrapping sleeve 1 .

[0029] Specifically, a cavity for installing the heating wire 2 is opened inside the wrapping sleeve 1, and the heating wire 2 is inserted inside the cavity. A control component for controlling the heat generation of the heating wire 2 is provided at one end of the wrapping sleeve 1. The control component includes a connecting wire 3 and a temperature control device 4. The temperature control device 4 is mounted on the outer wall of the connecting wire 3. The connecting wire 3 is used to provide electrical energy to the heating wire 2, and the temperature control device 4 is used to adjust the amount of heat generated by the heating wire 2. The heating wire 2 is wavy, and one end of the connecting wire 3 is electrically connected to one end of the heating wire 2.

[0030] Furthermore, the wrapping sleeve 1 is made of soft rubber material, such as EPDM. Ethylene propylene rubber has excellent ozone resistance, UV resistance, weather resistance and aging resistance, and ranks first among general rubbers. It has good electrical insulation, chemical resistance, impact elasticity, acid and alkali resistance, low specific gravity, and can be highly filled. At the same time, it is heat-resistant up to 150°C and low-temperature resistant up to -50°C. The heating wire 2, connecting wire 3 and temperature control device 4 constitute the entire heating device, which is connected to the external socket through the connecting wire 3 to supply electricity to the heating wire 2. Heat is generated by the heating wire 2 and filled in the cavity of the wrapping sleeve 1. The temperature control device 4 is used to adjust the temperature generated by the heating wire 2. The working principle of the heating wire 2, connecting wire 3 and temperature control device 4 is the same as that of the existing electric blanket. The heating wire 2 is wavy and is laid in the cavity in an S shape.

[0031] Specifically, the outer wall of the cavity inner wall is fixedly connected to the top of the thermal insulation layer 6, the air hole 7 is opened on the side of the cavity inner wall away from the thermal insulation layer 6, and one end of the air hole 7 is connected to the inner wall of the cavity.

[0032] Furthermore, the thermal insulation layer 6 is made of mineral wool, and the thermal insulation layer 6 is composed of a surface layer of mineral wool. Mineral wool has the characteristics of low bulk density, low thermal conductivity, non-flammability, heat resistance, frost resistance, corrosion resistance, fearlessness of insects, and good chemical stability. The thermal insulation layer 6 is glued to the inner wall of the cavity away from the air hole 7 to form a partition between cold and hot, thereby ensuring that the heat generated by the heating wire 2 can be fully retained in the cavity, and then flow to the pump body through the air hole 7 to heat and insulate the pump body.

The mounting parts 5 and the air vent 7 are arranged adjacent to each other. The magnetic strip 51 adopts the existing rubber soft magnetic strip, which is used for magnetic fixation with the pump body. The multiple magnetic strips 51 are arranged at intervals to facilitate the magnetic strip 51 to fit the shape of the pump body more closely. The adhesive layer 52 is glue or double-sided tape, which is used to bond and fix the magnetic strip 51 to the wrapping sleeve 1.

[0035] A water pump body comprises the above-mentioned anti-freeze cracking mechanism, and the water pump body is sleeved inside the anti-freeze cracking mechanism.

[0036] Furthermore, when using the anti-freeze cracking mechanism, the wrapping sleeve 1 is wrapped around the outer wall of the pump body, and the magnetic strip 51 is magnetically attracted to the outside of the pump body to fix the wrapping sleeve 1 to the outer wall of the pump body. At this time, by connecting the wire 3 to the socket, the temperature control device 4 is adjusted according to the actual situation, and the output temperature of the heating wire 2 is controlled. Heat flows to the pump body through the air vent 7 to heat and insulate the pump body to ensure that the liquid inside the pump body does not freeze, thereby preventing the pump body from freezing and cracking. The wrapping sleeve 1 can also wrap the water outlet pipe and water inlet pipe of the pump body according to actual usage.
