[0025] An automatic ice hockey puck launching device for testing solar modules, the structure of which further includes a control system; the control system includes an ice hockey puck speedometer 6, an ice hockey puck storage tank valve 16, a pneumatic controller 18, and a thermometer 26; the ice hockey puck speedometer 6 is located at the outlet of the ice hockey puck launching barrel 7, the ice hockey puck storage tank valve 16 is located at the connection between the ice hockey puck storage tank 15 and the ice hockey puck launching barrel 7, the pneumatic controller 18 is located at the air inlet of the air storage tank 19, and the thermometer 26 is located inside the side wall of the ice hockey puck storage tank 15; the air storage tank 19 is connected to an external compressed gas pipeline 17 through the pneumatic controller 18; during operation, the air pressure inside the air storage tank 19 is adjusted according to the pneumatic controller 18, and the corresponding ice hockey puck is controlled to enter the ice hockey puck launching barrel 7 by opening or closing the ice hockey puck storage tank valve 16 and cooperating with the ice hockey puck pushing device, the internal temperature of the ice hockey puck storage tank 15 is monitored and measured according to the thermometer 26, the speed of the ice hockey puck when it is launched is monitored according to the ice hockey puck speedometer 6, and the magnitude of the required air pressure inside the air storage tank 19 is determined according to the ice hockey puck exit speed monitored by the ice hockey puck speedometer 6; the compressed gas pipeline 17 is preferably a compressed air pipeline.

[0026] The connection between the ice hockey puck storage tank 15 and the ice hockey puck launching barrel 7 is located between the ice hockey puck baffle 8 and the compressed gas valve 21.

[0027] When the hockey puck baffle 8 is closed, the hockey puck baffle 8 is in airtight contact with the inner wall of the hockey puck firing chamber 7. The airtight contact can ensure no air leakage before the hockey puck baffle 8 is opened. The hockey puck pusher 12 is in airtight contact with the inner surface of the side wall of the hockey puck storage tank 15 to ensure the airtightness inside the hockey puck storage tank 15. During use, after the previous hockey puck is fired, first close the hockey puck baffle 8, then close the compressed gas valve 21, and then open the hockey puck storage tank valve 16. Use the hockey puck pushing device to push forward a distance equal to the diameter of a hockey puck, and push the next hockey puck into the hockey puck firing chamber 7. Close the hockey puck storage tank valve 16, and then open the compressed gas valve 21 again and open the hockey puck baffle 8 to complete the firing of the next hockey puck. By analogy, complete the continuous automatic firing of several hockey pucks. By using the method of first closing the hockey puck baffle 8 and then closing the compressed gas valve 21 after the previous hockey puck is fired, the gas pressure between the hockey puck baffle 8 and the compressed gas valve 21 inside the hockey puck firing chamber 7 at this time is higher than the external atmospheric pressure and higher than the air pressure inside the hockey puck storage tank 15. When the hockey puck storage tank valve 16 is opened again and the hockey puck is pushed forward by the hockey puck pushing device, since the gas pressure between the hockey puck baffle 8 and the compressed gas valve 21 inside the hockey puck firing chamber 7 is higher than the air pressure inside the hockey puck storage tank 15 at this time, part of the gas between the hockey puck baffle 8 and the compressed gas valve 21 enters the hockey puck storage tank 15. At the same time, under the action of the hockey puck pushing device, part of the gas in the hockey puck storage tank 15 enters the hockey puck firing chamber 7, realizing the air flow exchange between the gas between the hockey puck baffle 8 and the compressed gas valve 21 and the gas in the hockey puck storage tank 15. The cold gas in the hockey puck storage tank 15 enters the hockey puck firing chamber 7 to play a certain role in cooling the hockey puck firing chamber 7, avoiding the problem that the hockey puck firing chamber 7 is prone to heat during continuous firing. In addition, the gas between the hockey puck baffle 8 and the compressed gas valve 21 enters the hockey puck storage tank 15 and is cooled by the refrigeration device, indirectly realizing the cooling of the hockey puck firing chamber 7 by the refrigeration device, avoiding the problem that the hockey puck firing chamber 7 is prone to heat under the condition of compressed gas doing work during continuous firing. On the other hand, although the hockey puck pushing device pushes forward a distance equal to the diameter of a hockey puck each time, due to the inertia of the hockey puck movement, it is easy for two hockey pucks to fall into the hockey puck firing chamber 7 together. By controlling the gas pressure between the hockey puck baffle 8 and the compressed gas valve 21 inside the hockey puck firing chamber 7 to be higher than the air pressure inside the hockey puck storage tank 15, when the hockey puck storage tank valve 16 is opened again and the hockey puck is pushed forward by the hockey puck pushing device, the air pressure blocking effect is conducive to avoiding the situation that two hockey pucks fall into the hockey puck firing chamber 7 together due to the inertia of the hockey puck movement.

[0028] The compressed gas stored in the air storage tank 19 is preferably compressed air.

[0029] The hockey puck storage tank 15 is in a cylindrical tubular shape. The inner diameter of the hockey puck storage tank 15 is larger than the diameter of the stored hockey puck 5 and smaller than twice the diameter of the stored hockey puck 5; preferably, the inner diameter of the hockey puck storage tank 15 is larger than the diameter of the hockey puck and smaller than 1.2 times the diameter of the hockey puck; preferably, the length of the hockey puck storage tank 15 is larger than 11 times the diameter of the hockey puck, and more preferably, the length of the ball storage tank 15 is 11 to 15 times the diameter of the hockey puck, which is convenient for storing 11 to 15 hockey pucks; in use, several hockey pucks 5 can be pre-placed in the hockey puck storage tank 15 of the hockey puck storage device. The several hockey pucks 5 are arranged in a row along the length direction of the hockey puck storage tank 15 inside the hockey puck storage tank 15. The first hockey puck is next to the hockey puck storage tank valve 16 at the connection between the hockey puck storage tank 15 and the hockey puck firing chamber 7, and the last hockey puck contacts the hockey puck pusher 12; when the hockey puck firing system moves to the position where it needs to fire, the hockey puck storage tank valve 16 at the connection between the hockey puck storage tank 15 and the hockey puck firing chamber 7 is opened, and the hockey puck 5 in the hockey puck storage tank 15 is pushed towards the hockey puck firing chamber 7 by the hockey puck pushing device. The hockey puck pushing device pushes forward a distance equal to the diameter of one hockey puck each time, and exactly one hockey puck is pushed into the hockey puck firing chamber 7 each time. The hockey puck entering the hockey puck firing chamber 7 is blocked in the hockey puck firing chamber 7 by the hockey puck baffle 8. When it is necessary to shoot the hockey puck outwards, the compressed gas valve 21 is opened and the hockey puck baffle 8 is opened. The compressed gas in the gas storage tank 19 impacts the hockey puck in the hockey puck firing chamber 7 and shoots out from the outlet of the hockey puck firing chamber 7; after each hockey puck is fired, first the hockey puck baffle 8 is closed, then the compressed gas valve 21 is closed, and then the hockey puck storage tank valve 16 is opened again. The hockey puck pushing device is used to push forward a distance equal to the diameter of one hockey puck, and the next hockey puck is pushed into the hockey puck firing chamber 7. Then the compressed gas valve 21 is opened again and the hockey puck baffle 8 is opened to complete the firing of the next hockey puck. By analogy, the continuous automatic firing of several hockey pucks is completed; when continuously firing hockey pucks using the present invention, since the hockey pucks are directly stored in the hockey puck storage tank 15, the process of manually transporting the hockey pucks from the hockey puck refrigerator to the hockey puck launcher in the prior art is omitted, the time for firing the hockey puck is shortened, and it can be ensured that the time for each hockey puck to be launched out by the hockey puck firing system after leaving the hockey puck storage device is within 1 minute; the present invention improves the firing efficiency of the hockey puck, avoids the uncertain factors generated by manually taking and placing the hockey pucks, and reduces the uncertainty of the test results.

[0030] The side wall of the hockey puck storage tank 15 is preferably made of a metal material with a thermal conductivity coefficient ≥ 100 W / m·k, and the side wall material of the hockey puck storage tank 15 is more preferably copper.

[0031] The control system further includes a controller 3; the controller 3 is respectively connected to a thermometer 26, a puck speedometer 6, a puck storage tank valve 16, a pressure controller 18, a compressed gas valve 21, a front and rear movement motor 4, a left and right movement motor 23, a puck pushing motor 11, a refrigeration compressor 27, and a puck baffle 8 through signal lines; the controller 3 extracts the values of the puck speedometer 6 and the thermometer 26 through the signal lines, and the controller 3 controls the opening or closing of the puck storage tank valve 16, the pressure controller 18, the compressed gas valve 21, the front and rear movement motor 4, the left and right movement motor 23, the puck pushing motor 11, the refrigeration compressor 27, and the puck baffle 8 through the signal lines; the compressed gas valve 21 is preferably a compressed air solenoid valve; the puck storage tank valve 16 is preferably a puck storage tank solenoid valve.

[0032] The first signal input end of the controller 3 is connected to the signal output end of the thermometer 26, the second signal input end of the controller 3 is connected to the signal output end of the puck speedometer 6, the first signal output end of the controller 3 is connected to the signal input end of the puck storage tank solenoid valve 16, the second signal output end of the controller 3 is connected to the signal input end of the pressure controller 18, the third signal output end of the controller 3 is connected to the signal input end of the compressed gas valve 21, the fourth signal output end of the controller 3 is connected to the signal input end of the front and rear movement motor 4, the fifth signal output end of the controller 3 is connected to the signal input end of the left and right movement motor 23, the sixth signal output end of the controller 3 is connected to the signal input end of the puck pushing motor 11, the seventh signal output end of the controller 3 is connected to the signal input end of the refrigeration compressor 27, and the eighth signal output end of the controller 3 is connected to the signal input end of the puck baffle 8.

[0033] During operation, the controller 3 obtains the value of the thermometer 26 and controls the refrigeration compressor 27 to start. The refrigeration compressor 27 uses the heat exchange principle to make the refrigerant reach a certain temperature. The refrigerant flows into the refrigerant pipe 25 wound around the puck storage tank 15 through the refrigerant outflow pipe 28. The refrigerant pipe 25 conducts the refrigerant temperature to the outer wall of the puck storage tank 15 and forms a heat exchange with the outer wall of the puck storage tank 15. Since the outer wall is a metal material with good heat conduction, the temperature inside and outside the puck storage tank 15 can quickly become consistent, making the overall temperature of the puck storage tank 15 consistent; the refrigerant reduces the temperature of the puck storage tank 15, and the refrigerant temperature rises. The refrigerant flows into the refrigeration compressor 27 through the refrigerant return pipe 29. The refrigeration compressor 27 cools the refrigerant again. When the refrigerant reduces the temperature of the puck storage tank 15 to the set temperature, the power of the refrigeration compressor 27 is reduced to keep the refrigerant at a certain temperature, so as to keep the puck storage tank 15 at a certain temperature, and further store the puck 5 at a constant temperature.
