Specifically, the delivery pipe comprises an input pipe 21 and an output pipe 22, the input end of the first infusion mechanism 3 is connected to the input pipe 21, the output end of the first infusion mechanism 3 is connected to the output pipe 22, and the input pipe 21 and the output pipe 22 are respectively positioned at the upstream and the downstream of the first infusion mechanism 3. The input pipeline 21 is used for connecting a heat source or a pipeline connected with the heat source, the output pipeline 22 is used for connecting a heat sink or a pipeline connected with the heat sink, and the first liquid conveying mechanism 3 can convey the heat medium generated by the heat source to the heat sink. In the heating system, water is generally used as the heating medium, so in this embodiment, the first fluid delivery mechanism 3 is a circulating pump, but in other embodiments, the first fluid delivery mechanism 3 may be selected according to actual needs, for example, when the heating medium is gas, the first fluid delivery mechanism 3 is a vacuum pump.
The water replenishment tank 4 is also provided in the case 1, and is connected to a municipal tap water pipe through a pipe, and the water replenishment tank 4 is connected to a delivery pipe through a water replenishment pipe 41. The water tank 4 can store a preset amount of water therein to replenish water to the heating system. The second liquid conveying mechanism 5 is arranged on the water replenishing pipeline 41, and when the second liquid conveying mechanism 5 works, water in the water replenishing tank 4 can be conveyed into the conveying pipeline so as to replenish water for the heating system. In the heating system, water is generally used as the heating medium, so in this embodiment, the second liquid delivery mechanism 5 is a water replenishing pump, but in other embodiments, the second liquid delivery mechanism 5 can be selected according to actual needs, for example, when the heating medium is gas, the first liquid delivery mechanism 3 is a vacuum pump.
The heat supply pump station further comprises a control cabinet 7, the control cabinet 7 is arranged in the box body 1, a PLC control system is arranged in the control cabinet 7 and is electrically connected with the circulating pump and the water replenishing pump, automatic control of the heat supply pump station is achieved, functions such as unattended operation and remote monitoring are achieved, the control cabinet 7 is a common control structure in a pump station in the prior art, and detailed description is omitted.
At present, in order to avoid heat loss when the heat medium flows in the pipe network, heat supply efficiency is improved, the outside or the inside of the pipeline in the pipe network is generally provided with the heat preservation, therefore, although the temperature of the heat medium in input pipeline 21 and output pipeline 22 is higher, the heat that gives off to in the box 1 is very little, be close to zero, consequently, winter in the north, the temperature in the box 1 and external environment's temperature phase difference are very little, so when external environment temperature is lower, the water in moisturizing box 4 and moisturizing pipeline 41 is iced easily, thereby influence the normal clear of moisturizing. Therefore, in order to avoid the water in the replenishing water tank 4 and the replenishing water pipeline 41 from freezing, the heat supply pump station further comprises a radiator 6, and the radiator 6 is arranged in the tank body 1 and is used for providing heat for the tank body 1 so as to maintain the temperature in the tank body 1 at a preset temperature, in the embodiment, the preset temperature is 5 ℃ +/-2 ℃, and in other embodiments, the preset temperature can be set according to actual needs.
Specifically, in the present embodiment, the heat sink 6 includes a plurality of heat dissipation pipes, and the heat dissipation pipes are made of a metal material, which has a good heat transfer effect, but in other embodiments, the heat sink 6 may have other structures capable of dissipating heat. The radiator 6 is connected to the conveying pipeline through a branch pipeline, and heat of a heating medium in the conveying pipeline is transferred to the box body 1 through the radiator 6, so that water in the water replenishing tank 4 and the water replenishing pipeline 41 is prevented from freezing.

Partial heat medium after the circulation pump pressurization enters the radiator 6 through the first branch pipeline, heat medium gives off heat in the radiator 6, the temperature is reduced, the heat medium after the temperature is reduced enters the input pipeline 21 through the second branch pipeline, because the pressure of the heat medium after the circulation pump pressurization is large, the flow rate is fast, and the diameter of the branch pipeline (equipment is carried out according to actual needs) is small, therefore, no conveying mechanism such as a pump needs to be arranged on the branch pipeline, the heat medium circularly flows among the conveying pipeline, the branch pipeline and the radiator 6 under the action of the circulation pump, and the heat is given off in the radiator 6. In addition, since the amount of the heat medium flowing into the radiator 6 is small, the influence on the entire heating system is small, and almost none.
In addition, a control valve (not shown in the figure) is arranged on the first branch pipeline, a temperature detector (not shown in the figure) is arranged in the control cabinet 7, and the control valve and the temperature detector are electrically connected to the PLC control system. When the temperature detector detects that the temperature in the box body 1 reaches a preset temperature, a signal can be transmitted to the PLC control system, and the PLC control system controls the control valve to be closed; when the temperature detector detects that the temperature in the box body 1 is lower than the preset temperature, a signal can be transmitted to the PLC control system, and the PLC control system controls the control valve to be opened. In this embodiment, the control valve is an electromagnetic valve, and the temperature detector is a temperature sensor, but in other embodiments, the control valve may also be in other structures capable of being opened and closed, and the temperature detector may also be in other structures capable of detecting temperature.
In conclusion, by arranging the radiator 6, the heat can be conveyed into the box body 1 by utilizing the partial heat medium in the conveying pipeline, so that when the temperature of the external environment is lower, the temperature in the box body 1 can still be kept at the preset temperature, the water in the water replenishing tank 4 and the water replenishing pipeline 41 is prevented from freezing, and the normal operation of water replenishing is ensured.
The heating system provided by the embodiment can avoid the water in the water replenishing tank 4 and the water replenishing pipeline 41 from being frozen by adopting the heat supply pump station, and ensures the normal operation of water replenishing.
