[0038] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0040] In the embodiments of the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings or are used to describe the relative positional relationships of components in the vertical, perpendicular or gravity direction.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with exemplary embodiments.

[0042] like Figure 1 and Figure 3 As shown, the first exemplary embodiment of the utility model provides a garbage compressor, which includes a compressor base plate 101, a heating system, a heat generation system and a controller 12. The heating system includes a heating circulation liquid circuit 2 for conveying a refrigerant such as a coolant and contacting with the compressor base plate 101 for heat transfer, and the heat generation system is used to heat the refrigerant to increase the temperature of the compressor base plate 101, and includes a heat generation circulation liquid circuit 3 for conveying a heat medium such as a coolant; the controller 12 communicates with the heating system and the heat generation system respectively to control the circulation flow of the heating circulation liquid circuit 2 and the heat generation circulation liquid circuit 3 respectively.

[0043] It can be seen that the garbage compressor of this exemplary embodiment can use the heat generation system to heat the refrigerant in the heating circulation liquid circuit 2, so that the refrigerant in the heating circulation liquid circuit 2 is heated to heat the compressor base plate 101, thereby increasing the temperature of the compressor base plate 101, effectively preventing the compressor base plate 101 from freezing, and facilitating the unloading of garbage in the garbage compressor. In addition, the heating circulation liquid circuit 2 has a good insulation effect and can achieve continuous heating of the compressor base plate 101. Overall, by heating the compressor base plate 101, the garbage compressor in the utility model can be applied to the use needs of high-altitude cold areas and cold seasons.

[0044] In an optional or preferred embodiment, the heat generating system includes a heat exchanger 4 and a heat generating executive component, wherein the heat generating executive component can generate heat during operation, and a heat generating circulation fluid circuit 3 is formed between the heat exchanger 4 and the heat generating executive component. In other words, the heat medium in the heat generating circulation fluid circuit 3 can be heated by the heat generating executive component after flowing through the heat generating executive component. At the same time, the heat exchanger 4 is connected to the heating circulation fluid circuit 2 by a pipeline, so that the heat medium in the heat generating circulation fluid circuit 3 and the refrigerant in the heating circulation fluid circuit 2 can exchange heat in the heat exchanger 4, that is, the refrigerant in the heating circulation fluid circuit 2 is heated by the heat medium in the heat generating circulation fluid circuit 3, so that the refrigerant in the heating circulation fluid circuit 2 is heated to heat the compressor base plate 101.

[0045] Specifically, refer to Figure 1and Figure 3 The garbage compressor 1 is arranged on a garbage truck or a hook-arm truck, the heat generating system is the engine water cooling system of the garbage truck or the hook-arm truck, the heat generating executive component is the engine 5 of the garbage truck or the hook-arm truck, and the heat generating circulation liquid circuit 3 is the engine water cooling circulation circuit. Therefore, by using the engine 5 as the heat generating executive component, the residual heat generated by the operation of the engine 5 can be effectively utilized to heat the compressor base plate 101, which is beneficial to improving the energy utilization rate of the garbage truck or the hook-arm truck, reducing energy consumption and being more environmentally friendly on the one hand, and can realize rapid cooling of the engine 5, thereby improving the mechanical efficiency of the engine 5.

[0046] In this embodiment, other heat generating devices may be selected as heat generating execution components. For example, heat generating devices such as electric heaters and heat pumps may be selected as heat generating execution components for use, and this embodiment does not limit this.

[0047] In other embodiments, the heat generating system may include a heating device capable of directly heating the heating circulation fluid circuit 2. For example, an electric heating device may be selected to be arranged on the heating circulation fluid circuit 2. As long as the heating device can directly heat the refrigerant in the heating circulation fluid circuit 2, the setting of the heat exchange device can be omitted. This embodiment does not limit this.

[0048] In an optional or preferred embodiment, referring to Figure 3 , the heating circulation liquid circuit 2 includes a heating liquid circuit inlet and a heating liquid circuit outlet, and the garbage compressor includes a first quick-change connector 6 and a second quick-change connector 7. The first quick-change connector 6 is used to connect the heating liquid circuit outlet and the refrigerant inlet of the heat exchanger 4 respectively, and the second quick-change connector 7 is used to connect the heating liquid circuit inlet and the refrigerant outlet of the heat exchanger 4 respectively. It can be understood that the first quick-change connector 6 and the second quick-change connector 7 can be separately disassembled into a male head and a female head. Therefore, when it is necessary to heat the compressor base plate 101, the first quick-change connector 6 and the second quick-change connector 7 can be connected, so that the heating liquid circuit outlet and the refrigerant inlet of the heat exchanger 4 are interconnected, and the heating liquid circuit inlet and the refrigerant outlet of the heat exchanger 4 are interconnected, thereby realizing a heat exchange connection between the heating system and the heat generation system. The key is that the first quick-change connector 6 and the second quick-change connector 7 can be quickly disassembled and assembled to meet the use requirements of the heating system for quick separation or quick contact with the heat generation system. For example, when the garbage compactor 1 leaves the chassis to unload garbage, the first quick-change connector 6 and the second quick-change connector 7 can be disassembled respectively to quickly separate the heating system from the heat generation system, so that the heating system can follow the garbage compactor 1 to leave the chassis, or the heating system can be replaced. Overall, by providing the first quick-change connector 6 and the second quick-change connector 7, the versatility of the heating system can be improved.

[0049] It should be noted that, in this embodiment, the first quick-change connector 6 and the second quick-change connector 7 can be connector components such as mechanical quick-change connectors or hydraulic quick-change connectors, as long as they can achieve rapid disassembly and assembly and connection of the fluid path, and this embodiment does not limit this.

[0050] In an optional or preferred embodiment, referring to Figure 3 The heating system includes a refrigerant storage tank 8, a refrigerant power device 9 such as a hydraulic pump, and a heat transfer component 10. The heating circulation liquid path 2 is formed between the refrigerant storage tank 8, the refrigerant power device 9 and the heat transfer component 10. The heat transfer component 10 contacts the bottom surface of the compressor base plate 101. When the heating system is running, the refrigerant power device 9 can pump the refrigerant stored in the refrigerant storage tank 8 to the heat generating system for heating treatment. The heated refrigerant continues to flow to the heat transfer component 10, and the heat transfer component 10 transfers heat to the compressor base plate 101, thereby heating the compressor base plate 101. Subsequently, the cooled refrigerant flows out of the heat transfer component 10 and returns to the refrigerant storage tank 8, thereby realizing the circulation of the refrigerant in the heating circulation liquid path 2.

[0051] Furthermore, the heating circulation liquid circuit 2 includes a liquid inlet liquid circuit 201 and a liquid return liquid circuit 202 which are cyclically connected, and the heat transfer component 10 is located between the liquid inlet liquid circuit 201 and the liquid return liquid circuit 202 .

[0052] Specifically, the liquid inlet circuit 201 includes a plurality of branch liquid inlets arranged in sequence along the refrigerant conveying direction, the liquid return circuit 202 includes a plurality of branch liquid return ports which are spaced one by one with the plurality of branch liquid inlets, and the heat transfer component 10 includes a plurality of heat transfer branch pipes 1001 which are arranged under the compressor bottom plate 101 of the vehicle floor and are uniformly arranged one by one with the plurality of branch liquid inlets and the plurality of branch liquid return ports, and the two branch pipe ports of the heat transfer branch pipe 1001 are respectively connected to the corresponding branch liquid inlets and the branch liquid return ports.

[0053] In other words, when the refrigerant circulates in the heating circulation liquid circuit 2, the heated refrigerant can be diverted to the multiple heat transfer branches 1001 through the multiple diverting liquid inlets in the liquid inlet circuit 201, and after heat exchange with the compressor base plate 101 in the multiple heat transfer branches 1001, it converges to the return liquid circuit 202 through the multiple diverting liquid return ports to recover the cooled refrigerant. It can be seen that by providing multiple heat transfer branches 1001, on the one hand, uniform heat transfer between the heat transfer component 10 and the compressor base plate 101 can be achieved to prevent local icing, and on the other hand, the structure of the heat transfer component 10 can be simplified, which is conducive to realizing the one-way short-distance flow of the refrigerant without passing through a complex pipeline structure, thereby improving the heat transfer efficiency of the heating system.

[0054] In order to further improve the heat transfer efficiency of the heating system, refer to Figure 2The compressor bottom plate 101 is formed with a plurality of bottom plate heat transfer cavities 101a through which a plurality of heat transfer branches 1001 pass. The garbage compressor further includes a heat insulating material 101b disposed below the compressor bottom plate 101. Thus, when the refrigerant in the heating circulation fluid circuit 2 flows through the heat transfer component 10, its heat can be transferred from the bottom plate heat transfer cavity 101a to the plate surface of the compressor bottom plate 101. Meanwhile, the heat insulating material 101b can keep the heat transfer component 10 in the bottom plate heat transfer cavity 101a insulated and prevent heat loss, which is beneficial to further improve the heat transfer efficiency of the heating system and increase the heating speed of the compressor bottom plate 101.

[0055] In a specific embodiment, referring to Figure 2 The garbage compactor may also include a groove plate disposed under the compressor bottom plate 101 and a heat insulating material 101b disposed under the groove plate. The groove plate and the compressor bottom plate 101 can enclose a bottom plate flow guiding cavity 101c for guiding the refrigerant. Therefore, when the heated refrigerant passes through the bottom plate flow guiding cavity 101c, it can contact the compressor bottom plate 101 and directly heat the bottom plate, further improving the heating efficiency.

[0056] In order to realize automatic control of heating the compressor base plate 101, the garbage compressor of the exemplary embodiment further includes a controller 12 disposed in the cab of the garbage truck or hook arm truck, and the controller 12 can communicate with the heating system and the heat generation system respectively, so as to control the start and stop of the circulation flow of the heating circulation liquid circuit 2 and the heat generation circulation liquid circuit 3 respectively. Figure 3 , the controller 12 can establish communication with the refrigerant power device 9 in the heating system and the heat medium power device 11 in the heat generation system respectively. When the compressor base plate 101 needs to be heated, the heat medium power device 11 can be started by the controller 12 to make the heat medium in the heat generation circulation liquid circuit start to circulate, and then the refrigerant power device 9 can be started by the controller 12 to make the refrigerant in the heating circulation liquid circuit 2 start to circulate, thereby realizing the automatic control of the heating system and the heat generation system. Of course, you can also choose to use a manual mode to control the start and stop of the heating system and the heat generation system. For example, a control panel that can send instructions to the controller can be set in the cab of a garbage truck or a hook truck, and the heating system and the heat generation system can be controlled by manually operating the control panel. The control mode of controlling the heating system and the heat generation system is not limited in this embodiment.

Obviously, the garbage sanitation vehicle has all the technical effects brought by the above-mentioned garbage compressor, so they are not described here in detail.
