The diesel engine converts chemical energy into rotational mechanical energy, drives the compressor to rotate and output a continuous, stable, large-flow compressed air, providing the aircraft with a standard air source. However, when the air source device is started at low temperature, the lubricating oil in the compressor and other components becomes viscous and it will be difficult to start, increasing energy consumption. At the same time, low-temperature starting will also damage the motor system. The compressor will continue to overheat when running at high speed, and air entering the compressor will produce condensed water that will damage the compressor.

Its technical solution has the function of heating the motor and the compressor part of the compressor when the device cannot be started in a low temperature environment to prevent the compressor from being damaged by the low temperature, and the function of switching to blowing cold air to the compressor to dissipate heat after the compressor starts working.

[0004] To this end, how to provide a wide temperature range aircraft ground air source device with a driving source temperature control function, which can heat up the compressor part when starting the device in a low temperature environment to prevent the compressor from being damaged by low temperature, and can switch to blowing cold air to the compressor after the compressor starts to dissipate heat to prevent the compressor from overheating for a long time. Realizing wide temperature range temperature control of the compressor is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention proposes a ground air source device for aircraft with a wide temperature range and a driving source temperature control function, aiming to solve the technical problems that the above-mentioned traditional air source device has poor temperature control effect on the compressor part, cannot effectively heat up the compressor part when starting the device in a low temperature environment to prevent low temperature from damaging the compressor, and cannot effectively blow cold air to the high-speed running compressor after the compressor starts to dissipate heat to prevent the compressor from overheating for a long time.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] The present invention provides a wide temperature range aircraft ground air source device with a driving source temperature control function, comprising:

[0008] An installation base, on which a power device, a compressor and an air pump are installed; a power output end of the power device is drivingly connected to the compressor and the air pump to provide power;

[0009] A vortex tube group is arranged on the mounting base; the air outlet of the air pump is connected to the air inlet of the vortex tube group to supply air, so that the vortex tube group generates hot air and cold air;

[0010] A gas diversion mechanism is arranged on the mounting base; the gas diversion mechanism is connected to the vortex tube group to control the distribution and transportation of hot air and cold air output by the vortex tube group to the compressor, thereby regulating the operating temperature of the compressor.

[0011] When the ground air source device for wide temperature range aircraft with a driving source temperature control function of the present invention is used, the power equipment provides a rotational driving force for the compressor and the air pump to drive them to work; the compressor provides compressed gas for the aircraft; the air pump delivers compressed gas to the vortex tube group, the vortex tube group generates hot air and cold air, and the function of the gas diversion mechanism is to distribute and deliver the hot air and cold air to the compressor according to the needs of the compressor; under extremely cold weather conditions, since the lubricating oil inside the compressor is in a relatively viscous state, the starting energy consumption will increase, and low-temperature starting will also cause damage to the motor system; when the compressor is just started, the hot air generated by the vortex tube group is distributed to the compressor through the gas diversion mechanism for temperature increase; as the compressor runs, it heats up itself, and at this time, the cold air generated by the vortex tube group is distributed to the compressor through the gas diversion mechanism for cooling to maintain the working temperature of the compressor. The present invention can start the device in a low temperature environment to heat up the compressor part, thereby preventing the compressor from being damaged by low temperature, and can switch to blowing cold air to the compressor to dissipate heat after the compressor starts to prevent the compressor from overheating for a long time, thereby realizing wide temperature range temperature control of the compressor.

[0012] As a further improvement of the above technical solution, the gas diversion mechanism includes a diversion valve group and a temperature sensing control mechanism; the hot gas inlet of the diversion valve group is connected to the hot gas port of the vortex tube group, and the cold gas inlet of the diversion valve group is connected to the cold gas port of the vortex tube group; the hot gas outlet 1 and the cold gas outlet 1 of the diversion valve group are arranged corresponding to the compressor to perform air blowing temperature control;

[0013] The temperature sensing end of the temperature sensing control mechanism is arranged corresponding to the compressor, and its control end is connected to the diverter valve group to adjust the opening and closing states of the hot air outlet 1 and the cold air outlet 1 according to the detected temperature.

[0014] The beneficial effect of the above technical solution is that the temperature state of the compressor can be monitored by the temperature sensing control mechanism, and then the opening and closing states of the hot air outlet 1 and the cold air outlet 1 of the diverter valve group can be controlled, so as to realize the delivery of hot air to quickly heat up when the compressor is in a low-temperature state, and the temperature rises to a certain value, and the delivery of cold air to cool down to balance its body temperature when it works normally.

[0015] As a further improvement of the above technical solution, the diverter valve group includes a diverter valve 1, a diverter valve 2, a pipeline assembly, an elastic linkage limit mechanism and a valve mechanism for cold and hot air switching control;

[0016] The pipeline assembly includes a hot air main pipe, a cold air main pipe, a hot air branch pipe 1, a cold air branch pipe 1 and a switching control pipe;

[0017] The hot air inlet of the diverter valve 1 is connected to the hot air outlet of the vortex tube group through the hot air main pipe; the cold air inlet of the diverter valve 2 is connected to the cold air outlet of the vortex tube group through the cold air main pipe; an injection structure for injecting air to control the temperature of the compressor body is arranged on the periphery of the compressor; the hot air outlet 1 of the diverter valve 1 is connected to the injection structure through the hot air branch pipe 1 to transport hot air, and the cold air outlet 1 of the diverter valve 2 is connected to the injection structure through the cold air branch pipe 1 to transport cold air;

[0018] The two ends of the elastic linkage limiting mechanism are respectively transmission-connected to the valve core 1 of the diverter valve 1 and the valve core 2 of the diverter valve 2, so that the valve core 1 is elastically limited in a state of opening the hot air outlet 1 of the diverter valve 1, and the valve core 2 is elastically limited in a state of closing the cold air outlet 1 of the diverter valve 2; a valve core push plate is sliding and sealingly connected in the valve cavity of the diverter valve 1; the valve core push plate is fixed to one end of the valve core 1; one end of the switching control pipe is connected to the hot air main pipe, and the other end is connected to the valve cavity of the diverter valve 1, and the valve core push plate can be driven to slide by the airflow, thereby pushing the valve core 1 to close the hot air outlet 1 of the diverter valve 1, and pushing the valve core 2 to open the cold air outlet 1 of the diverter valve 2;

[0019] The valve mechanism is installed on the switching control tube, and the temperature sensing control mechanism is connected to the valve mechanism to control the valve mechanism to open and close the switching control tube.

[0020] The beneficial effects of the above technical solution are as follows: when the compressor is just started, the temperature sensing control mechanism detects that the compressor is in a low temperature state, and the elastic linkage limit mechanism elastically limits the valve core 1 to a state of opening the hot air outlet 1 of the diverter valve 1, and elastically limits the valve core 2 to a state of closing the cold air outlet 1 of the diverter valve 2; at this time, the valve mechanism is in a state of blocking and closing the switching control tube to prevent the hot air discharged from the hot air outlet of the vortex tube group from flowing through the switching control tube, and the hot air discharged from the hot air outlet of the vortex tube group passes through the hot air main pipe, the diverter valve 1, the hot air branch pipe 1, and the jet structure in turn and is sprayed onto the compressor body for rapid temperature increase; after starting, the compressor gradually heats up, and when the temperature sensing control mechanism detects that the compressor is in a high temperature state, the valve mechanism is controlled to open the switching control tube. At this time, a part of the hot air discharged from the hot air outlet of the vortex tube group is diverted to the switching control tube. Control pipe, hot air enters the valve cavity of diverter valve 1 through the switching control pipe and pushes the valve core push plate, thereby overcoming the elastic force of the elastic linkage limiting mechanism to push valve core 1 and valve core 2 to move synchronously, and transition to the state where valve core 1 closes the hot air outlet 1 of diverter valve 1 and valve core 2 opens the cold air outlet 1 of diverter valve 2; at this time, the cold air discharged from the cold air outlet of the vortex tube group passes through the cold air main pipe, diverter valve 2, cold air branch pipe 1, and the jet structure in turn and is sprayed onto the compressor body to cool down and balance the heat generation of the compressor; when the power equipment is shut down, the hot air and cold air will stop being supplied, and the elastic linkage limiting mechanism will reset under the action of the elastic force, and valve core 1 will return to the reset state of opening the hot air outlet 1 of diverter valve 1, and valve core 2 will return to the reset state of closing the cold air outlet 1 of diverter valve 2; the valve mechanism returns to the state of blocking and closing the switching control pipe.

[0021] As a further improvement of the above technical solution, the diverter valve 1 and the diverter valve 2 are arranged horizontally opposite to each other; the elastic linkage limit mechanism includes a mounting base fixed above the vortex tube group, a transmission gear rotatably connected to the mounting base, a transmission rack 1 and a transmission rack 2 adapted to mesh with the transmission gear, and a reset spring;

[0022] One end of the transmission rack 1 and one end of the transmission rack 2 are symmetrically arranged on both sides of the transmission gear; the other end of the transmission rack 1 is transmission-connected to the valve core 1, and the other end of the transmission rack 2 is transmission-connected to the valve core 2;

[0023] One end of the return spring is connected to the transmission gear, and the other end is connected to the mounting base to provide a return torque to the transmission gear.

[0024] The beneficial effects of the above technical solution are: the reset spring provides torque for the transmission gear, so that the transmission rack 1 elastically limits the valve core 1, and the transmission rack 2 elastically limits the valve core 2; the thrust torque of the air pressure in the switching control tube on the valve core push plate needs to overcome the torque of the reset spring to trigger the action of the valve core 1 and the valve core 2; the transmission rack 1 and the transmission rack 2 are both meshed on the transmission gear, realizing the linkage between the two.

[0025] As a further improvement of the above technical solution, the temperature sensing control mechanism includes a temperature difference power generation component, an electromagnetic switch mechanism, a battery and an electromagnetic limit mechanism;

[0026] One end of the temperature difference power generation component is connected to the jet structure, and the other end is connected to the compressor body to perform temperature difference power generation; the temperature difference power generation component is electrically connected to the electromagnetic switch mechanism, the electromagnetic switch mechanism is electrically connected to the battery, the battery is electrically connected to the electromagnetic limit mechanism, and the electromagnetic switch mechanism is used to control the temperature difference power generation component to charge the battery and control the battery to supply power to the electromagnetic limit mechanism;

[0027] The electromagnetic limiting mechanism is transmission-connected to the valve mechanism to release and open or lock and close the valve mechanism.

[0028] The beneficial effect of the above technical solution is: in a low temperature environment, the compressor is still in a low temperature state when it is just started, and the vortex tube group supplies hot air to the jet structure to make it in a high temperature state, so that a large temperature difference is generated at both ends of the thermoelectric power generation component, thereby powering the electromagnetic switch mechanism and controlling its switching action. At this time, the electromagnetic switch mechanism controls the thermoelectric power generation component to charge and store energy for the battery, and at the same time, the valve mechanism remains locked and closed, that is, the switch control tube is not ventilated, so that the jet structure continuously sprays hot air to warm up the compressor. As the temperature of the compressor rises and gradually transitions to the normal operating temperature, the temperature difference at both ends of the thermoelectric power generation component decreases and the power generation efficiency decreases. At this time, the electromagnetic switch mechanism controls the battery to power the electromagnetic limit mechanism; the energized electromagnetic limit mechanism controls the valve mechanism to switch to the release open state, switches the control tube to supply air, pushes the valve core push plate, and then cuts off the hot air outlet 1 of the diverter valve to close the hot air supply, and opens the cold air outlet 1 of the diverter valve 2 to supply cold air to the jet structure, thereby balancing the heating of the compressor in the working state.

[0029] As a further improvement of the above technical solution, the electromagnetic limiting mechanism includes an electromagnet and a limiting claw;

[0030] The valve mechanism includes a pipe baffle, which is located in a horizontal section inside the switching control tube, and its top is hinged on the top wall of the switching control tube to form a rotating valve; a limiting hole is provided at the top of the pipe baffle; a through hole corresponding to the limiting hole is provided on the top wall of the switching control tube; the lower end of the limiting claw is movably penetrated in the through hole, and can be correspondingly inserted into the limiting hole to limit the pipe baffle in a vertically closed state; the battery is electrically connected to the electromagnet 1 for power supply; the electromagnet 1 is installed on the switching control tube and arranged above the limiting claw so as to attract the limiting claw upward when power is turned on to make it disengage from the limiting hole, thereby releasing the pipe baffle.

[0031] The beneficial effects of the above technical solution are: after the electromagnet is energized, it attracts the limit claw upward to release the pipe baffle, and the pipe baffle rotates under the push of hot air to open the switching control tube; after the pipe baffle rotates, the limit hole can be separated from the through hole; when the battery power is exhausted and no longer supplies power to the electromagnet, and at the same time, after the power equipment, compressor and air pump are stopped, the air pressure in the switching control tube decreases, and when the pipe baffle is vertically reset, the limit claw can naturally fall into the limit hole to re-limit.

[0032] As a further improvement of the above technical solution, a one-way pressure relief door is installed on the pipeline baffle, which can be opened by air pressure to discharge the gas in the switching control pipe when the valve core push plate is reset.

[0033] The beneficial effect of the above technical solution is that the one-way pressure relief valve can exhaust the switching control pipe after the power equipment, compressor and air pump are shut down to allow the valve core push plate to be smoothly reset vertically.

[0034] As a further improvement of the above technical solution, it also includes a box body installed on the installation base, and the power equipment, the compressor, the air pump, the vortex tube group and the gas diversion mechanism are all installed inside the box body; an exhaust port is opened on the box body, and an exhaust fan is installed on the box body corresponding to the exhaust port.

[0035] The beneficial effect of the above technical solution is that the box body plays a role in isolating and protecting the internal equipment, and the exhaust fan can discharge the excess hot air accumulated on the top of the box body through the exhaust port.

[0036] As a further improvement of the above technical solution, it also includes a gas moisture removal mechanism connected to the air inlet end of the compressor;

[0037] The gas moisture removal mechanism includes a condensation box and a condensation plate installed in the inner cavity of the condensation box; the condensation box has an air inlet and an air outlet connected to the inner cavity, and the air outlet of the condensation box is connected to the suction port of the compressor; the cold air port of the vortex tube group is connected to the inner cavity of the condensation plate through a pipeline to send cold air to the condensation plate for cooling.

[0038] The beneficial effects of the above technical solution are: the air inlet of the condenser box is connected to the external atmosphere; the cold air generated by the vortex tube group is used to cool the condenser plate, and the external air with moisture enters the condenser box and hits the condenser plate, which can condense and liquefy the atmospheric moisture, thereby increasing the dryness of the air discharged from the air outlet of the condenser box, thereby effectively preventing the generation of condensed water in the compressor and causing damage to the compressor.

[0039] As a further improvement of the above technical solution, the gas moisture removal mechanism also includes a drying box; one port of the drying box is connected to and communicated with the air outlet of the condensing box, and the other port of the drying box is connected to and communicated with the air intake of the compressor to dry the air flowing through;

[0040] The hot air outlet of the vortex tube group is connected to the inner cavity of the drying box through a pipeline to transport hot air and neutralize the temperature of the cold air transported by the condensing box.

[0041] The beneficial effects of the above technical solution are: the drying box further dries the air entering the compressor; and the hot air from the vortex tube group is distributed to the drying box to neutralize the cold air delivered by the condensing box, so that the temperature of the air inhaled by the compressor is suitable, which is conducive to the normal operation of the compressor and increases its service life.

[0042] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a wide temperature range aircraft ground air source device with a driving source temperature control function, which has the following advantages and beneficial effects:

[0043] 1. The present invention provides a wide temperature range aircraft ground air source device with a driving source temperature control function. When the device is started at low temperature, the compressor can be heated by hot air. When the temperature of the compressor rises, the action of the valve mechanism can be automatically controlled through the cooperation of a temperature difference power generation component, an electromagnetic switch mechanism, a battery and an electromagnetic limit mechanism to cool down the compressor with increased temperature, prevent the compressor from overheating due to long-term operation, and realize wide temperature range temperature control of the compressor.

[0044] 2. The present invention provides a ground air source device for aircraft with a wide temperature range and a driving source temperature control function. When the power equipment, the compressor and the air pump stop working, the pipe baffle can be reset to a vertical posture; the one-way pressure relief door installed on the pipe baffle can allow the gas in the switching control pipe to leak out smoothly to ensure the smooth reset of the pipe baffle; the limit claw separated from the adsorption of the electromagnet can fall into the limit hole of the pipe baffle to re-fix the pipe baffle, so as to prevent the hot gas from directly driving the valve core push plate to switch at the next startup.

[0045] 3. The present invention provides a ground air source device for aircraft with a wide temperature range and a driving source temperature control function. The hot air and cold air generated by the vortex tube group are further used to adjust the compressor inlet temperature and humidity. When starting at low temperature, the cold air passes through the condensation plate in the condensation box to condense and remove moisture from the air. The drying box dries and removes moisture, and can also serve as a mixing area for hot air and cold air to balance the compressor inlet temperature. It effectively reduces the temperature difference and moisture before and after the gas enters the compressor, preventing condensation from being generated in the compressor to damage the compressor.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] like Figures 1 to 11 As shown, a wide temperature range aircraft ground air source device with a driving source temperature control function comprises:

[0064] A mounting base 1 is provided on one side of the mounting base 1, and a power device 2, a compressor 3 and an air pump 4 are mounted on the mounting plate 11; the power output end of the power device 2 is transmission-connected to the compressor 3 and the air pump 4 to provide power;

[0065] The vortex tube group 5 is arranged on the mounting base 1; the air outlet of the air pump 4 is connected to the air inlet of the vortex tube group 5 to supply air, so that the vortex tube group 5 generates hot air and cold air;

[0066] The gas diversion mechanism 6 is arranged on the mounting base 1 ; the gas diversion mechanism 6 is connected to the vortex tube group 5 to control the distribution and transportation of the hot gas and cold gas output by the vortex tube group 5 to the compressor 3 , thereby regulating the working temperature of the compressor 3 .

[0067] When a wide-temperature-range ground air source device for aircraft with a driving source temperature control function of the present embodiment is used, the power equipment 2 provides a rotational driving force for the compressor 3 and the air pump 4 to drive them to work; the compressor 3 provides compressed gas for the aircraft; the air pump 4 delivers compressed gas to the vortex tube group 5, and the vortex tube group 5 generates hot air and cold air. The function of the gas diversion mechanism 6 is to distribute and transport the hot air and cold air to the compressor 3 according to the needs of the compressor 3; under extremely cold weather conditions, since the lubricating oil inside the compressor 3 is in a relatively viscous state, the starting energy consumption will increase, and low-temperature starting will also cause damage to the motor system; when the compressor 3 is just started, the hot air generated by the vortex tube group 5 is distributed to the compressor 3 through the gas diversion mechanism 6 for temperature increase; as the compressor 3 runs, it generates heat itself. At this time, the cold air generated by the vortex tube group 5 is distributed to the compressor 3 through the gas diversion mechanism 6 for cooling to maintain the working temperature of the compressor 3. The present invention can start the device in a low-temperature environment to heat up the compressor part, thereby preventing the compressor from being damaged by low temperature, and can switch to blowing cold air to dissipate heat to the compressor after the compressor starts working to prevent the compressor from overheating for a long time, thereby realizing wide temperature range temperature control of the compressor.

[0068] Specifically, the mounting base 1 can be a walking vehicle body to increase the flexibility of the mobile arrangement; the power equipment 2 can be a diesel engine. The vortex tube group 8 is composed of a plurality of vortex tubes connected. When the diesel engine is started, the air pump 4 and the compressor 3 are driven to work at the same time. At this time, the gas pumped out by the air pump 4 is divided into two streams of hot and cold air through the vortex tube group 5. The hot air of 90-120 degrees is ejected from one end of the hot air main pipe 6131, and the cold air of -20 degrees is ejected from one end of the cold air main pipe 6132.

[0069] In some embodiments, the gas diversion mechanism 6 includes a diversion valve group 61 and a temperature sensing control mechanism 62; the hot gas inlet of the diversion valve group 61 is connected to the hot gas port of the vortex tube group 5, and the cold gas inlet of the diversion valve group 61 is connected to the cold gas port of the vortex tube group 5; the hot gas outlet 1 and the cold gas outlet 1 of the diversion valve group 61 are arranged corresponding to the compressor 3 to perform air blowing temperature control;

[0070] The temperature sensing end of the temperature sensing control mechanism 62 is arranged corresponding to the compressor 3, and its control end is connected to the diverter valve group 61 to adjust the opening and closing states of the hot air outlet 1 and the cold air outlet 1 according to the detected temperature.

[0071] The temperature state of the compressor 3 can be monitored by the temperature sensing control mechanism 62, and then the opening and closing states of the hot air outlet 1 and the cold air outlet 1 of the diverter valve group 61 can be controlled, so as to realize that when the compressor 3 is in a low temperature state, hot air is delivered to quickly heat up the temperature, and when the temperature rises to a certain value and normal operation, cold air is delivered to cool down to balance its body temperature.

[0072] In some embodiments, the diverter valve assembly 61 includes a diverter valve 1 611, a diverter valve 2 612, a pipeline assembly 613, an elastic linkage limit mechanism 614, and a valve mechanism 615 for switching control of hot and cold air;

[0073] The pipeline assembly 613 includes a hot air main pipe 6131, a cold air main pipe 6132, a hot air branch pipe 1 6133, a cold air branch pipe 1 6134 and a switch control pipe 6135;

[0074] The hot air inlet of the diverter valve 1 611 is connected to the hot air outlet of the vortex tube group 5 through the hot air main pipe 6131; the cold air inlet of the diverter valve 2 612 is connected to the cold air outlet of the vortex tube group 5 through the cold air main pipe 6132; an injection structure 31 for injecting air to control the temperature of the compressor 3 body is fixedly installed above the compressor 3; the hot air outlet of the diverter valve 1 611 is connected to the injection structure 31 through the hot air branch pipe 1 6133 to transport hot air, and the cold air outlet of the diverter valve 2 612 is connected to the injection structure 31 through the cold air branch pipe 1 6134 to transport cold air;

[0075] The two ends of the elastic linkage limiting mechanism 614 are respectively connected to the valve core 1 6111 of the diverter valve 1 611 and the valve core 2 6121 of the diverter valve 2 612, so as to elastically limit the valve core 1 6111 in a state of opening the hot air outlet 1 of the diverter valve 1 611, and to elastically limit the valve core 2 6121 in a state of closing the cold air outlet 1 of the diverter valve 2 612; a valve core push plate 6112 is slidably and sealedly connected in the valve cavity of the diverter valve 1 611; the valve core push plate 6112 is fixed to one end of the valve core 1 6111; one end of the switching control pipe 6135 is connected to the hot air main pipe 6131, and the other end is connected to the valve cavity of the diverter valve 1 611, and the valve core push plate 6112 can be driven to slide by the airflow, thereby pushing the valve core 1 6111 to close the hot air outlet 1 of the diverter valve 1 611, and pushing the valve core 2 6121 to open the cold air outlet 1 of the diverter valve 2 612;

[0076] The valve mechanism 615 is installed on the switching control tube 6135 , and the temperature sensing control mechanism 62 is connected to the valve mechanism 615 to control the opening and closing of the switching control tube 6135 .

[0077] When the compressor 3 is just started, the temperature sensing control mechanism 62 detects that the compressor 3 is in a low temperature state, and the elastic linkage limit mechanism 614 elastically limits the valve core 1 6111 to the state of opening the hot air outlet 1 of the diverter valve 1 611, and elastically limits the valve core 2 6121 to the state of closing the cold air outlet 1 of the diverter valve 2 612; at this time, the valve mechanism 615 is in a state of blocking and closing the switching control pipe 6135 to prevent the hot air discharged from the hot air outlet of the vortex tube group 5 from flowing through the switching control pipe 6135, and the hot air discharged from the hot air outlet of the vortex tube group 5 passes through the hot air main pipe 6131, the diverter valve 1 611, the hot air branch pipe 1 6133, and the jet structure 31 in sequence and is sprayed onto the compressor 3 body for rapid temperature increase; after starting, the compressor 3 gradually heats up, and when the temperature sensing control mechanism 62 detects that the compressor 3 is in a high temperature state, the valve mechanism 615 is controlled to open the switching control pipe 6135. At this time, part of the hot air discharged from the hot air outlet of the vortex tube group 5 is diverted to the switching control pipe 6135, and the hot air passes through the switching control pipe 61 35 enters the valve cavity of the diverter valve 1 611 and pushes the valve core push plate 6112, thereby overcoming the elastic force of the elastic linkage limit mechanism 614 to push the valve core 1 6111 and the valve core 2 6121 to move synchronously, and transition to a state in which the valve core 1 6111 closes the hot air outlet 1 of the diverter valve 1 611 and the valve core 2 6121 opens the cold air outlet 1 of the diverter valve 2 612; at this time, the cold air discharged from the cold air outlet of the vortex tube group 5 passes through the cold air main pipe 6132, the diverter valve 2 612, and the cold air branch pipe in sequence. One 6134, the jet structure 31 sprays onto the compressor 3 body to cool down and balance the heat generation of the compressor 3; when the power equipment 2 is shut down, the hot air and cold air will stop being supplied, the elastic linkage limit mechanism 614 will reset under the action of the elastic force, the valve core one 6111 will return to the reset state of opening the diverter valve one 611 hot air outlet one, and the valve core two 6121 will return to the reset state of closing the diverter valve two 612 cold air outlet one; the valve mechanism 615 will return to the state of blocking and closing the switching control tube 6135.

[0078] In some embodiments, the diverter valve 1 611 and the diverter valve 2 612 are arranged horizontally opposite to each other; the elastic linkage limit mechanism 614 includes a mounting base 6141 fixed above the vortex tube group 5, a transmission gear 6142 rotatably connected to the mounting base 6141, a transmission rack 1 6143 and a transmission rack 2 6144 adapted to mesh with the transmission gear 6142, and a reset spring 6145;

[0079] One end of the transmission rack 1 6143 and one end of the transmission rack 2 6144 are symmetrically arranged on both sides of the transmission gear 6142; the other end of the transmission rack 1 6143 is transmission-connected to the valve core 1 6111, and the other end of the transmission rack 2 6144 is transmission-connected to the valve core 2 6121;

[0080] One end of the return spring 6145 is connected to the transmission gear 6142 , and the other end is connected to the mounting base 6141 to provide a return torque to the transmission gear 6142 .

[0081] The reset spring 6145 provides torque for the transmission gear 6142, so that the transmission rack 1 6143 elastically limits the valve core 1 6111 and the transmission rack 2 6144 elastically limits the valve core 2 6121; the thrust torque of the air pressure in the switching control tube 6135 on the valve core push plate 6112 needs to overcome the torque of the reset spring 6145 to trigger the action of the valve core 1 6111 and the valve core 2 6121; the transmission rack 1 6143 and the transmission rack 2 6144 are both meshed on the transmission gear 6142, realizing the linkage between the two.

[0082] In some embodiments, the temperature sensing control mechanism 62 includes a temperature difference power generation component 621, an electromagnetic switch mechanism 622, a battery 623 and an electromagnetic limit mechanism 624;

[0083] One end of the temperature difference power generation component 621 is connected to the jet structure 31, and the other end is connected to the compressor 3 body to perform temperature difference power generation; the temperature difference power generation component 621 is electrically connected to the electromagnetic switch mechanism 622, the electromagnetic switch mechanism 622 is electrically connected to the battery 623, the battery 623 is electrically connected to the electromagnetic limit mechanism 624, and the electromagnetic switch mechanism 622 is used to control the temperature difference power generation component 621 to charge the battery 623 and control the battery 623 to supply power to the electromagnetic limit mechanism 624;

[0084] The electromagnetic limiting mechanism 624 is connected to the valve mechanism 615 in a transmission manner to release and open or lock and close the valve mechanism 615 .

[0085] In a low-temperature environment, the compressor 3 is still in a low-temperature state when it is just started. The vortex tube group 5 supplies hot air to the jet structure 31 to make it in a high-temperature state, so that a large temperature difference is generated at both ends of the temperature difference power generation component 621, thereby powering the electromagnetic switch mechanism 622 and controlling its switching action. At this time, the electromagnetic switch mechanism 622 controls the temperature difference power generation component 621 to charge and store energy for the battery 623. At the same time, the valve mechanism 615 remains locked and closed, that is, the switching control tube 6135 is not ventilated, so that the jet structure 31 continuously sprays hot air to heat the compressor 3. As the temperature of the compressor 3 increases and gradually transitions to the normal operating temperature, the temperature difference at both ends of the temperature difference power generation component 621 decreases and the power generation efficiency decreases. At this time, the electromagnetic switch mechanism 622 controls the battery 623 to supply power to the electromagnetic limit mechanism 624; the energized electromagnetic limit mechanism 624 controls the valve mechanism 615 to switch to a released open state, switches the control tube 6135 to supply air, pushes the valve core push plate 6112, and then cuts off the hot air outlet of the diverter valve 611 to close the hot air supply, and opens the cold air outlet of the diverter valve 612 to supply cold air to the jet structure 31, thereby balancing the heat generated by the compressor 3 in the working state.

[0086] Specifically, the thermoelectric power generation assembly 621 includes a thermoelectric power generation sheet 6211 and two heat-conducting rods 6212; one end of a heat-conducting rod 6212 is fixed to one end of the thermoelectric power generation sheet 6211, and the other end is inserted into the compressor 3 body; one end of another heat-conducting rod 6212 is fixed to the other end of the thermoelectric power generation sheet 6211, and the other end contacts and is connected to the jet structure 31; the two heat-conducting rods 6212 conduct heat to the two end surfaces of the thermoelectric power generation sheet 6211 respectively. The outer peripheral walls of the two heat-conducting rods 6212 and the thermoelectric power generation sheet 6211 are wrapped with a heat-insulating layer 6213 for heat insulation, so that the thermoelectric power generation sheet 6211 is only affected by the temperature of the ends away from the two heat-conducting rods.

[0087] Specifically, a plurality of heat sinks 32 are arranged on the compressor 3 body. The heat sinks 32 are preferably made of aluminum material, which can accelerate the speed of heat transfer to the outside.

[0088] In some embodiments, the electromagnetic limiting mechanism 624 includes an electromagnet 6241 and a limiting claw 6242;

[0089] The valve mechanism 615 includes a pipe baffle 6151, which is located in the horizontal section of the switching control tube 6135, and its top is hinged on the top wall of the switching control tube 6135 to form a rotating valve; a limiting hole 6151A is provided at the top of the pipe baffle 6151; a through hole 6135A corresponding to the limiting hole 6151A is provided on the top wall of the switching control tube 6135; the lower end of the limiting claw 6242 is movably penetrated in the through hole 6135A, and can be correspondingly inserted into the limiting hole 6151A to limit the pipe baffle 6151 in a vertical closed state; the battery 623 is electrically connected to the electromagnet 1 6241 for power supply; the electromagnet 1 6241 is installed on the switching control tube 6135 and arranged above the corresponding limiting claw 6242, so as to attract the limiting claw 6242 upward when power is turned on to make it escape from the limiting hole 6151A, thereby releasing the pipe baffle 6151.

[0090] After the electromagnet 1 6241 is energized, it attracts the limit claw 6242 upward to release the pipe baffle 6151, and the pipe baffle 6151 rotates under the push of hot air to open the switching control tube 6135; after the pipe baffle 6151 rotates, the limit hole 6151A can be separated from the through hole 6135A; when the battery 623 is exhausted and no longer supplies power to the electromagnet 1 6241, and at the same time, after the power equipment 2, the compressor 3 and the air pump 4 are shut down, the air pressure in the switching control tube 6135 decreases, and when the pipe baffle 6151 is vertically reset, the limit claw 6242 can naturally fall into the limit hole 6151A to limit it again.

[0091] Specifically, a return spring 6243 is installed between the upper part of the limiting claw 6242 and the outer wall of the switching control tube 6135, so that the upper end of the limiting claw 6242 can be quickly reset when it is separated from the attraction of the electromagnet 6241 and the lower end corresponds to the limiting hole 6151A.

[0092] Specifically, the electromagnetic switch mechanism 622 includes a fixed rod 6221, an electromagnet 6222, a trigger rod 6223, a trigger switch 1 6224 and a trigger switch 2 6225; the fixed rod 6221 is arranged horizontally, one end of which is fixedly connected to the temperature difference power generation sheet 6211, and the other end extends away from the body of the compressor 3; the battery 623 is fixed to the other end of the fixed rod 6221, and the electromagnet 2 6222 is fixed to the side of the fixed rod 6221 and close to one end of the battery 623; a slide rail 6227 is installed at the lower end of the electromagnet 6222, and the trigger rod 6223 is slidably connected to the slide rail 6227; the bottom end of the fixed rod 6221 is fixed with a trigger switch 1 6224, and the trigger switch 2 622 5 is located below the trigger switch 1 6224 and fixed on the battery 623; one end of the trigger rod 6223 is located between the trigger switch 1 6224 and the trigger switch 2 6225, so that it can abut against the trigger switch 1 6224 when it rises, and abut against the trigger switch 2 6225 when it falls; a limit spring 6226 is connected between the trigger rod 6223 and the electromagnet 2 6222, and the limit spring 6226 can make the trigger rod 6223 elastically press against the trigger switch 2 6225, and the electromagnet 2 6222 can be powered on to attract the trigger rod 6223 upward to make it abut against the trigger switch 1 6224 to open; when the electromagnet 2 6222 is powered off, the limit spring 6226 can make the trigger rod 6223 reset downward. The trigger switch 1 6224 is a switch that connects the temperature difference power generation sheet 6211 to the battery 623, and the trigger switch 2 6225 is a switch that connects the battery 623 to the electromagnet 1 6241.

[0093] Specifically, when the device is just started, when the temperature difference between the compressor 3 and the jet structure 31 is large, a temperature difference of about 100 degrees appears at both ends of the thermoelectric power generation sheet 6211; the thermoelectric power generation sheet 6211 is electrically connected to the second electromagnet 6222 to supply power to it, so that it attracts the trigger rod 6223 upward to abut against the first trigger switch 6224, and connects the circuit between the thermoelectric power generation sheet 6211 and the battery 623 to charge the battery 623. When the temperature of the compressor 3 rises and the temperature difference at both ends of the thermoelectric power generation sheet 6211 is reduced, the second electromagnet 6222 no longer attracts the trigger rod 6223, and the limit spring 6226 presses the trigger rod 6223 downward to abut against the second trigger switch 6225, so that the circuit between the battery 623 and the first electromagnet 6241 is connected. At this time, the first electromagnet 6241 attracts the limit claw 6242 upward to make it escape from the limit hole 6151A, and releases the pipe baffle 6151 to switch between hot air and cold air.

[0094] In some embodiments, in order to solve the problem that when the valve core push plate 6112 is reset, there is gas in the switching control tube 6135 that cannot be discharged and affects the reset; a one-way pressure relief valve 6151B is installed on the pipeline baffle 6151, which can be opened by air pressure to discharge the gas in the switching control tube 6135 when the valve core push plate 6112 is reset.

[0095] The one-way pressure relief valve 6151B can exhaust the switching control pipe 6135 after the power equipment 2, the compressor 3 and the air pump 4 are shut down so that the valve core push plate 6112 can be smoothly reset vertically.

[0096] Specifically, a limiting boss 6135B is fixed below the pipe baffle 6151 at the inner bottom end of the switching control pipe 6135 , and the limiting boss 6135B can resist and prevent the pipe baffle 6151 from rotating in the opposite direction of the air supply direction of the switching control pipe 6135 .

[0097] Specifically, a pressure relief port is provided in the middle of the pipe baffle 6151; the one-way pressure relief door 6151B is located on one side of the pipe baffle 6151 close to the limiting boss 6135B, the one-way pressure relief door 6151B is blocked at the pressure relief port and an elastic sheet 6151C is fixed on its upper portion, and the top of the elastic sheet 6151C is fixed to the upper portion of the pipe baffle 6151; the size of the one-way pressure relief door 6151B is larger than the size of the pressure relief port; the elastic sheet 6151C can elastically press the one-way pressure relief door 6151B against the surface of the pipe baffle 6151 to improve the sealing performance of the pressure relief port; when the switching control tube 6135 is reversely deflated, the elastic force of the elastic sheet 6151C can be overcome to push the one-way pressure relief door 6151B open, and after the switching control tube 6135 is deflated, the elastic sheet 6151C is reset to restore the pipe baffle 6151 to the state of blocking the pressure relief port.

[0098] Specifically, a limiting plate 6151D is fixed to the upper part of the pipe baffle 6151 corresponding to the elastic sheet 6151C away from the one-way pressure relief door 6151B, and the limiting plate 6151D is used to limit the bending deformation of the elastic sheet 6151C to prevent it from excessive bending and damage.

[0099] When the valve core push plate 6112 is reset, the gas in the squeeze switch control tube 6135 is pushed open the one-way pressure relief door 6151B to allow the gas to leak out. The limiting boss 6135B can keep the pipe baffle 6151 in a vertical position. The elastic sheet 6151C can allow the one-way pressure relief door 6151B to reset after the valve core push plate 6112 is reset. At the same time, the one-way pressure relief door 6151B is larger than the pressure relief port size of the pipe baffle 6151 so that it will not rotate in the opposite direction and affect the sealing effect of the pipe baffle 6151.

[0100] In some embodiments, it also includes a box body 7 installed on the mounting base 1, and the power equipment 2, the compressor 3, the air pump 4, the vortex tube group 5 and the gas diversion mechanism 6 are all installed inside the box body 7; an exhaust port 71 is opened on the upper part of the side wall of the box body 7, and an exhaust fan 72 is installed on the box body 7 corresponding to the exhaust port 71.

[0101] The box body 7 serves to isolate and protect the internal equipment, and the exhaust fan 72 can discharge the excess hot air accumulated on the top of the box body 7 through the exhaust port 71.

[0105] The air inlet of the condensation box 81 is connected to the external atmosphere; the cold air generated by the vortex tube group 5 is used to cool the condensation plate 82. When the external air with moisture enters the condensation box 81 and hits the condensation plate 82, the atmospheric moisture can be condensed and liquefied, so as to increase the dryness of the air discharged from the air outlet of the condensation box 81, thereby effectively preventing the generation of condensed water in the compressor 3 and causing damage to the compressor 3.

[0106] Specifically, there are multiple condensation plates 82, which are arranged at intervals along the ventilation direction of the condensation box 81 and staggered in the horizontal direction to construct a winding ventilation path in the inner cavity of the condensation box 81 to increase the condensation effect; the upper and lower ends of the condensation plate 82 respectively penetrate the top wall and bottom wall of the condensation box 81 and extend to the outside.

[0108] The hot air outlet of the vortex tube group 5 is connected to the inner cavity of the drying box 83 through a pipeline to transport hot air and neutralize the temperature of the cold air transported by the condensation box 81.

[0109] The drying box 83 further dries the air entering the compressor 3; and the hot air from the vortex tube group 5 is distributed to the drying box 83 to neutralize the cold air delivered by the condensing box 81, so that the temperature of the air inhaled by the compressor 3 is suitable, which is conducive to the normal operation of the compressor 3 and improves its service life.

[0110] Specifically, the drying box 83 contains a desiccant, and the desiccant may be a silica gel desiccant.

[0111] In some embodiments, in order to solve the problem that ice on the outside of the condensation plate 82 affects the cooling efficiency; the gas moisture removal mechanism 8 also includes a deicing mechanism 84; the deicing mechanism 84 includes a telescopic rod 841, a driving rod 842 and a plurality of scrapers 843; the telescopic rod 841 is installed on the outer wall of the condensation box 81, and scrapers 843 are arranged on both sides of the condensation plate 82 inside the condensation box 81, the telescopic end of the telescopic rod 841 is fixedly connected to the driving rod 842, and the other end of the driving rod 842 is movably inserted into the inner cavity of the condensation box 81 and fixedly connected to the plurality of scrapers 843; the lifting and lowering movement of the telescopic end of the telescopic rod 841 can drive the plurality of scrapers 843 to lift and lower at the same time through the driving rod 842 to scrape out the ice layer on both sides of the condensation plate 82. The scrapers 843 are regularly lifted and lowered to prevent the ice layer from being too thick and affecting the cooling and condensation effect.

[0112] In some embodiments, the gas moisture removal mechanism 8 also includes a cyclone separator 85; the air inlet end of the cyclone separator 85 is connected to the air outlet of the condensation box 81, and the air outlet end of the cyclone separator 85 is connected to a port of the drying box 44; the cyclone separator 85 can further remove moisture from the air discharged from the condensation box 81.

[0113] In some embodiments, the diverter valve 611 also includes a valve shell 6113; a hot gas inlet, a hot gas outlet one and a hot gas outlet two are provided on the valve shell 6113; the valve core 6111 is a three-way pipe structure with an air inlet port and two air outlet ports, and is slidably arranged in the valve shell 6113; the air inlet port of the valve core 6111 always corresponds to the hot gas inlet, and the two air outlet ports of the valve core 6111 can be connected to the hot gas outlet one and the hot gas outlet two one by one; the outer peripheral wall of the valve core 6111 is symmetrically fixed with anti-deflection protrusions 6114 that are adapted and slidably connected to the inner wall of the valve shell 6113 to prevent directional deflection when the outlet is switched by translational displacement; when the valve core 6111 is in a displacement switching state, its air outlet port can leave the hot gas outlet one, but the hot gas outlet two can be connected to at least one of the air outlet ports.

[0114] The second diverter valve 612 has the same structure as the first diverter valve 611, including a second valve housing 6123, on which a cold air inlet, a first cold air outlet and a second cold air outlet are provided. The first valve housing 6113 and the second valve housing 6123 are symmetrically arranged on both sides of the mounting base 6141, the other end of the transmission rack 1 6143 movably penetrates into the first valve housing 6113 and is fixed to the first valve core 6111, and the other end of the transmission rack 2 6144 movably penetrates into the second valve housing 6123 and is fixed to the second valve core 6121.

The other end of the switching control pipe 6135 is connected and communicated with the side of the valve housing 1 6113 away from the valve housing 2 6123.

[0116] Specifically, the pipeline assembly 613 also includes a hot air branch pipe 6136 and a cold air branch pipe 6137; one end of the hot air branch pipe 6136 is connected to and communicated with the hot air outlet 2 of the diverter valve 611, and the other end is connected to a port of the drying box 83; one end of the cold air branch pipe 6137 is connected to and communicated with the cold air outlet 2 of the diverter valve 612, and the other end is connected to the inner cavity of multiple condensation plates 82.

[0117] Specifically, the air inlet of the condenser box 81 is connected to the air inlet pipe 811; the air inlet pipe 811 runs through the box body 7 to connect to the external atmosphere; after the external air enters the air inlet pipe 811, it first enters the interior of the condenser box 81, and the -20 degrees Celsius cold air delivered by the cold air branch pipe 6137 passes through the interior of the condenser plate 82 to cool the air flow passing through the outer wall of the condenser plate 82. When the moisture in the air flow hits the staggered condenser plates 82, the moisture will condense on the outside of the condenser plate 82 to reduce the moisture in the intake air, and then the gas passes through the cyclone separator 85 to further remove moisture; before entering the drying box 83, it is mixed with the hot air entering from the hot air branch pipe 6136 to increase the temperature, which can reduce the temperature difference and moisture of the gas before and after entering the compressor 3, and prevent the generation of condensed water in the compressor 3 to damage the compressor.
