[0002] The non-negative pressure water supply device takes the municipal pipe network as the water source, makes full use of the original pressure of the municipal pipe network, forms a closed continuous relay pressurized water supply mode, has good energy-saving effect, and has no secondary pollution of water quality. It is the development and extension of the variable frequency constant pressure water supply device, and the non-negative pressure water supply device is an ideal energy-saving water supply device. It is a secondary water supply device that can be directly connected to the tap water pipe network without any side effects on the tap water pipe network.

[0003] The non-negative pressure water supply device realizes that the device does not generate negative pressure on the municipal pipe network through intelligent control technology and voltage stabilization compensation technology, and ensures uninterrupted water supply to the user pipe network. However, when the device is used in a relatively cold environment or area, it will cause failures or damages to the non-negative pressure water supply device, making it difficult to meet the actual working requirements, resulting in a great reduction in the applicable range of the non-negative pressure water supply device. Summary of the Utility Model

[0011] Further, the complete set of units is composed of a connecting pipeline, a pump group and valve parts, and the inlet pressure transmitter and the outlet pressure transmitter are connected through the complete set of units.

[0012] Further, an environmental detection temperature sensor is provided on the upper end surface of the base body, and the environmental detection temperature sensor is electrically connected to the intelligent control box.

[0013] Further, heating tubes are uniformly arranged at the lower end of the inner wall of the water tank body.

[0014] Further, the water outlet heating mechanism includes a water inlet pipe, a connecting pump body and a spiral pipe. The water inlet pipe is connected to one side of the water tank body, and the other end of the water inlet pipe is connected to the water outlet pressure transmitter. The connecting pump body is arranged at the upper end of the water tank body, and the lower end of the connecting pump body extends into the water tank body. The spiral pipe is connected to the output end of the connecting pump body, the spiral pipe is wound around the outer surface of the water outlet pressure transmitter, and the tail end of the spiral pipe is connected to the water tank body.

[0016] The utility model has the following beneficial effects:

[0017] The utility model can collect the data signals of the embedded temperature sensor and the environmental detection temperature sensor, and through the processing of the intelligent control box system. When the temperature is too low, the water pump is started to run at a low frequency to prevent the water pump from freezing due to the low water temperature, which can ensure the normal operation of the equipment in low temperature. At the same time, when the temperature is relatively low, the heating tubes in the water tank body can be turned on to heat the water in the water tank body. Then, through the guiding of the connecting pump body and the spiral pipe wound around the outside of the water outlet pressure transmitter, the water outlet pressure transmitter can be heated, which is convenient for subsequent use and can avoid caking due to water cooling and affecting the subsequent actual work requirements. Finally, the fan body can introduce gas, and through the spiral pipe, the inside of the protective bin can be heated, so as to ensure the temperature in the protective bin and avoid damage to the equipment at the upper end of the base body due to the low temperature in the protective bin.
