[0030] As Figures 1 to 6 shown, the design purpose of the utility model is to provide temperature suitable drinking water for livestock by using multiple heat sources, which can effectively reduce the inconvenience caused by multiple heating tanks heating respectively, thereby ensuring the safety of livestock drinking water. Example 1

[0031] A pasture drinking water system, comprising a heat source, a heat exchange box 2, a cold water storage tank 3, a drinking water tank 5 and a controller 6, the heat source is one or more than one centralized heating device, at least including a first heat source and a second heat source, the heat source includes but is not limited to a boiler 1, a solar water heater 4, an air source heat pump and other devices capable of concentrating heat energy. The heat source is located outside the livestock house, the heat exchange box 2 contains livestock drinking water, the heat exchange box 2 includes a shell and a heat exchange pipe, the heat exchange pipe is arranged in the shell, the shell is composed of three layers of inner layer, heat insulation layer and outer layer, the inner layer is in direct contact with the livestock drinking water; the heat insulation layer is composed of polyurethane foaming, polystyrene, PEF and other heat insulation materials, mainly used to isolate the influence of external temperature on the water temperature in the heat exchange box 2; the outer layer can be made of stainless steel plate or aluminum-zinc plated plate, mainly for protection and aesthetics. The cold water storage tank 3 is used to store filtered and purified tap water at room temperature, the outlet pipe of the cold water storage tank 3 and the outlet pipe of the heat exchange box 2 are provided with solenoid valves 8, opening the solenoid valve 8 can inject cold and hot water into the drinking water tank 5, so that the mixed water temperature in the drinking water tank 5 is suitable for livestock drinking, and the number of solenoid valves 8 corresponds to the number of drinking water tanks 5, which can supply water to each drinking water tank 5 as needed. The drinking water tank 5 is made of multiple 3mm thick steel plates, the overall surface of each drinking water tank 5 is hot galvanized, the top is open, and the drinking water tank 5 is dispersedly arranged in different areas of the livestock house according to the size of the livestock house and the quality of the livestock. Each drinking water tank 5 is provided with a temperature sensor 7 for detecting water temperature. The controller 6 is placed in the main control room, the controller 6 receives the water temperature feedback from the temperature sensor 7 in the drinking water tank 5, and adjusts the on-off state of the solenoid valve 8 according to the difference between the actual temperature in the drinking water tank 5 and the set temperature.

[0032] In this embodiment, the boiler 1 is used as the first heat source to provide warm water for the drinking water tank 5.

[0033] The boiler 1 is a hot water boiler, and its use is not limited, for example, the boiler 1 can be a boiler 1 for preheating drinking water for livestock alone, or a boiler 1 for providing drinking hot water for the daily life of a breeder, or a heating boiler for providing heating needs for a house or livestock shed in winter, etc. In order to save energy and reduce emissions, the heat source is preferably the heat energy formed by the waste heat of the boiler 1 or the heat energy realized by natural resources, that is, the consumption of energy can be reduced, and the cost of livestock breeding can be reduced.

[0034] The first heat source is a heating boiler in this embodiment. In winter, due to the low outdoor temperature in the north, in order to improve the indoor temperature, a boiler 1 is usually used for heating. The boiler 1 usually adds cold water on the water inlet side, and forms hot water by heating fuel, and the hot water enters the indoor through the water circulation pipeline to improve the indoor temperature, and the heat-exchanged warm water returns to the boiler 1 through the water circulation pipeline for continuous heating. Therefore, the boiler 1 has two cold end water sources, one is the water inlet side, and the other is the return water part of the water circulation pipeline. The outlet pipe of the water circulation pipeline of the boiler 1 is in communication with the heat exchange pipe arranged in the heat exchange box 2, and the water in the heat exchange pipe is heat-exchanged and then enters the return water part of the water circulation pipeline. The use of the waste heat of the boiler 1 to heat the drinking water in the heat exchange box 2 can save energy and reduce breeding costs.

[0035] The temperature sensor 7 feeds back the water temperature corresponding to the drinking trough 5 to the controller 6, the controller 6 compares the feedback temperature with the set temperature, and when the feedback temperature is lower than the adjustment range of the set temperature, the electromagnetic valve 8 is started and opened, and the cold and hot water is mixed in the drinking trough 5, so that the water temperature in the drinking trough 5 is rapidly raised to the set temperature range. When the temperature sensor 7 detects that the water temperature in the drinking trough 5 reaches the set temperature range, the electromagnetic valve 8 is closed. Thus, the purpose of centralized heating and suitable drinking water temperature of multiple drinking troughs 5 is achieved. Embodiment 2

[0036] In this embodiment, the first heat source is a boiler, but the heat exchange position is different from that of embodiment 1.

[0037] As shown in Figure 2 The structure of the drinking trough 5 is based on that of embodiment 1, and a heat preservation cavity 51 is additionally arranged at the bottom of the drinking trough 5 to facilitate the flow of hot water. The heat preservation cavity 51 is located inside the bottom of each drinking trough 5, and the outlet pipe of the water circulation pipeline of the boiler 1 is in communication with the heat preservation cavity 51 in each drinking trough 5.

[0038] The water circulation pipeline of the boiler 1 provides heat exchange for the room, and then flows into the heat preservation cavity 51 to provide heat preservation for the drinking water tank 5 by using the remaining heat. A plurality of drinking water tanks 5 can be connected in series or in parallel. In this embodiment, the heat preservation cavities 51 of all the drinking water tanks 5 are connected in series, and the water discharged after heat exchange in the heat preservation cavities 51 is again introduced into the water circulation pipeline of the boiler 1. An electromagnetic valve 8 is arranged on the water outlet pipe of the cold water storage tank 3 to supply the drinking water tank 5 or adjust the temperature of the drinking water. Embodiment 3

[0039] Based on the embodiments 1 and 2, in this embodiment, the solar water heater 4 is used as the second heat source.

[0040] As shown in Figure 3 Generally, the boiler 1 is installed near the kitchen or dormitory, and there is a distance between the boiler 1 and the livestock house. In winter, the water circulation pipeline exposed to the outdoor environment has a large heat loss. In order to reduce the heat loss before heat exchange and improve the heat exchange efficiency, in this embodiment, the second heat source, the solar water heater 4, is used to provide heat tracing for the part of the water circulation pipeline of the first heat source, the boiler 1, which is located outdoors.

[0041] The solar water heater 4 is a product available on the market, and the application only clarifies its use, without changing its structure. The solar water heater 4 mainly comprises a heat collector 41 and a liquid storage tank 42. The liquid storage tank 42 is used to store the heat exchange medium. The heat collector 41 is installed on the roof of the livestock house. The heat collector 41 absorbs solar radiation energy through its surface, and the absorbed heat energy is transferred to the heat exchange medium flowing through the surface of the heat collector 41 through heat conduction, so that the heat exchange medium in the pipeline is heated. The heat exchange medium can be selected from water, antifreeze, heat conducting oil and other materials according to the ambient temperature.

[0042] The heat tracing channel is formed between the heat tracing outer pipe and the outer wall of the circulation pipeline. The heat exchange medium enters one end of the heat tracing channel after being heated, and flows in the same direction as the water circulation pipeline of the boiler 1, and then flows out from the other end of the heat tracing channel. The water flowing out from the heat tracing channel flows back into the liquid storage tank 42 again to wait for heat exchange again. Embodiment 4

Specifically, one heat exchange pipe is connected in series with the water circulation pipeline of the boiler 1, and the other heat exchange pipe is connected with the liquid storage tank 42 through the outlet pipe of the heat collector 41. The water outlet of the heat exchange tank 2 and the water outlet of the cold water storage tank 3 are both communicated with the tank of the drinking water tank 5 through electromagnetic valves. Two different heat sources heat the drinking water tank 5 at the same time, which can effectively improve the heat exchange efficiency of the drinking water tank 5. Embodiment 6
