[0012] The present invention also discloses a method for using the helium recovery device of the above-mentioned helium detection equipment, comprising the following steps: S1: After turning on the main power, water is poured into the water tank. As the liquid level rises, the water squeezes the floating ring, and the floating ring rises along the water inlet pipe. When the trigger button is squeezed, the water pump starts, and the water pump draws water from the water tank through the water inlet pipe and transports it to the vertical cylinder through the return pipe. The water level in the vertical cylinder continues to rise until the water in the vertical cylinder falls into the curved pipe. After the water reaches the set height in the curved pipe, stop pouring water into the water tank, the liquid level in the water tank drops, the trigger button is no longer squeezed, and the water pump is turned off; S2: The pressurized helium to be recovered is stored in a temporary gas storage tank. The connecting pipe with a valve is connected to the temporary gas storage tank. After the valve is opened, the pressurized helium to be recovered enters the installation cylinder through the connecting pipe with a valve, and enters the curved pipe after being coarsely filtered through the coarse filter plate. The helium squeezes the water in the curved pipe into the vertical cylinder, and then the helium enters the water in the vertical cylinder. After being washed with water, it enters the installation box from the air guide pipe. After the adsorption sponge absorbs the water, the activated carbon mesh block absorbs the impurities, and then it is output to the external helium storage device through the outlet pipe for storage; S3: When the connecting pipe with valve in S2 is connected with the temporary gas storage tank, the driving motor is started, the driving motor drives the crank shaft to rotate, the crank shaft drives the stirring frame to stir the water in the vertical cylinder to ensure the uniformity of helium water washing, and the crank shaft synchronously drives the driving large gear to rotate, the driving large gear drives the driving small gear to accelerate the rotation, and the driving small gear drives the spline plug to rotate the reciprocating screw; The reciprocating screw drives the isolation plate to drive the plug rod to move the spline column downward, and the isolation plate drives the isolation ring to move downward until the isolation ring blocks the valve connection pipe. At this time, the installation cylinder no longer outputs helium to the curved pipe. At this time, the crank shaft rotates half a circle, and the crank shaft drives the linkage plate to stretch the elastic rope. The elastic rope pulls the L-shaped slider to partially detach it from the connecting square pipe. During the process, the spring is stretched, and part of the water in the vertical cylinder that has been cleaned by helium flows into the water tank through the connecting square pipe. At this time, the liquid level in the water tank rises, and when the floating ring squeezes the trigger button, the water pump starts to transport the water filtered by the filter cylinder to the vertical cylinder again; As the reciprocating screw continues to rotate, the reciprocating screw drives the isolation plate to drive the plug rod to move the spline column upward, and at the same time the isolation plate drives the isolation ring to move upward until the isolation ring is completely separated from the valve connection pipe. At this time, the installation cylinder continues to output helium to the curved pipe. At this time, the crank shaft rotates another half circle. During the process, the spring is reset, the linkage plate no longer stretches the elastic rope, and the L-shaped slider blocks the connecting square pipe. The water in the vertical cylinder that has been cleaned with helium no longer flows into the water tank. At this time, the liquid level in the water tank drops, and after the floating ring is separated from the trigger button, the water pump is turned off; S4: During the rotation of the reciprocating screw in S3, the reciprocating screw drives the cooperative large gear to rotate, the cooperative small gear drives the synchronous small gear to accelerate the rotation, the synchronous small gear drives the spline column to rotate, the spline column drives the synchronous large gear to rotate synchronously through the plug rod, the synchronous large gear drives the cooperative small gear to accelerate the rotation, and the cooperative small gear drives the upper retaining ring to rotate around the positioning ring. During the process, the upper retaining ring drives the lower retaining ring to rotate the cleaning disk. When the isolation ring in S3 completely blocks the valved connecting pipe, the cleaning disk cleans the coarse filter plate. When the isolation ring is separated from the valved connecting pipe, the pressurized helium to be recovered in the temporary gas storage tank blows the impurities on the coarse filter plate into the dust outlet square pipe, and then falls into the storage drawer for storage.

[0013] The present invention is further configured as follows: when the adsorption sponge and the activated carbon mesh block need to be replaced in S2, the main power supply is turned off, the valve on the valve connecting pipe is closed, the fastening bolt is rotated to disengage it from the fixing hole set on the upper part, and the disassembly plate is pulled downward, the disassembly plate drives the vertical plate to move the support plate downward, the support plate drives the two second tooth plates to move downward, the second tooth plates drive the gear roller to move the two first tooth plates upward synchronously, the first tooth plates drive the grooved bracket to move upward along the movable groove, and when the fastening bolt moves to the fixing hole set at the bottom, the fastening bolt is screwed into the fixing hole, at this time, the two grooved brackets drive the activated carbon mesh block and the adsorption sponge to disengage from the movable groove, the adsorption sponge and the activated carbon mesh block are removed, and they can be replaced, and then the disassembly plate is reset; During the descent of the disassembly and assembly plate, the special-shaped plate is driven to stretch the elastic rope downward, and the elastic rope pulls the L-shaped slider to partially detach it from the connecting square tube, so that part of the water in the vertical cylinder that has been cleaned by helium flows into the water tank. When the disassembly and assembly plate is reset, open the inspection door, take out the filter cylinder for cleaning, put the filter cylinder back, close the inspection door, and then use it again.

[0014] Beneficial effects of the present invention: Compared with the prior art, the advantages of the present invention are: (1) The present invention ensures that the helium to be recovered can be intermittently introduced into the circulating water washing component for water washing after coarse filtration through the coordination of a temporary gas storage tank, a circulating water washing component and an intermittent gas outlet component, thereby ensuring that solid impurities are thoroughly and effectively cleaned. At the same time, the circulation of water can be stopped when the helium is introduced, thereby ensuring that the helium is smoothly introduced into the adsorption filtration component for adsorption of water vapor and gas impurities, thereby providing a guarantee for the purity of helium recovery. When the helium is stopped from being introduced, the water is circulated to ensure the cleanliness of the water used. In addition, with the setting of the filtering and cleaning component, the impurities of the coarse filtration can be cleaned, thereby ensuring that the helium to be recovered is smoothly introduced into the circulating water washing component, thereby providing a reliable guarantee for the long-term use of the device.

[0015] (2) The present invention realizes automatic opening and closing of the water pump by setting the water inlet pipe, the floating plate and the trigger button. With the setting of the driving motor, the crank shaft, the linkage plate, the mounting frame, the disassembly plate, the elastic rope, the connecting square tube and the L-shaped slider, when the crank shaft rotates, the elastic rope can be used to stretch the L-shaped slider so that it is separated from the connecting square tube. With the setting of the spring and the docking frame, the L-shaped slider can be reset, that is, the connecting square tube can be controlled on and off, providing conditions for the intermittent discharge of the water after helium cleaning in the vertical tube into the water tank. With the setting of the lap ring and the filter cylinder, the impurities in the water after cleaning can be effectively filtered.

[0016] (3) The present invention realizes several turns of the driving pinion after the crank shaft rotates half a circle by cooperating with the driving large gear and the driving small gear. The arrangement of the spline plug, the reciprocating screw, the isolation plate and the isolation ring is coordinated to realize the upward or downward movement of the isolation ring, thereby providing control conditions for whether the valved connecting pipe is closed and establishing a cooperative relationship with whether the L-shaped slider blocks the connecting square pipe. That is, when the isolation ring completely blocks the valved connecting pipe, the L-shaped slider no longer blocks the connecting square pipe. When the isolation ring does not completely block the valved connecting pipe, the L-shaped slider blocks the connecting square pipe, thereby providing reliable guarantee for the smooth introduction of helium into the installation box.

[0017] (4) The present invention cooperates with the spline column, the synchronous pinion, the positioning frame, the plug rod, the synchronous large gear, the positioning ring, the cooperative large gear, the cooperative pinion, the upper retaining ring, the lower retaining ring, the cleaning disc, the positioning ring and the reserved groove. When the reciprocating screw rotates, the cleaning disc can be driven to accelerate the rotation. After the isolation ring completely blocks the valved connecting pipe, the cleaning disc can rotate and clean the coarse filter plate. After the isolation ring is separated from the valved connecting pipe, with the cooperation of the dust removal square pipe, the storage box and the storage drawer, the impurities cleaned from the coarse filter plate can be blown into the storage drawer for storage, which is convenient for cleaning.

[0018] (5) The present invention cooperates with the disassembly plate, the vertical plate, the support plate, the second tooth plate, the gear, the first tooth plate, the slide groove and the grooved bracket, and the adsorption sponge and the activated carbon mesh block can be replaced by pulling downward. The setting of the fixing holes, the docking plate and the fastening bolts is combined to provide a guarantee for the stability of the disassembly plate. In addition, during the replacement of the adsorption sponge and the activated carbon mesh block, the water in the vertical cylinder can be introduced into the water tank by pulling the elastic rope, so as to clean the water after the helium is cleaned in the vertical cylinder, thereby providing a high purity guarantee for the subsequent helium filtration.

[0036] The method for using the helium recovery device of the above-mentioned helium detection equipment comprises the following steps: S1: After turning on the main power supply, water is poured into the water tank 7. As the liquid level rises, the water squeezes the floating ring 13. The floating ring 13 rises along the water inlet pipe 12. When the trigger button 14 is squeezed, the water pump 10 is started. The water pump 10 extracts water from the water tank 7 through the water inlet pipe 12 and transports it to the vertical cylinder 8 through the return pipe 11. The water level in the vertical cylinder 8 continues to rise until the water in the vertical cylinder 8 falls into the curved tube 39. After the water reaches the set height in the curved tube 39, the water filling into the water tank 7 is stopped, the liquid level in the water tank 7 drops, the trigger button 14 is no longer squeezed, and the water pump 10 is turned off. S2: The pressurized helium to be recovered is stored in the temporary gas storage tank 1. The valved connecting pipe 31 is connected to the temporary gas storage tank 1. After the valve is opened, the pressurized helium to be recovered enters the installation cylinder 30 through the valved connecting pipe 31, and enters the curved pipe 39 after being coarsely filtered by the coarse filter plate 32. The helium squeezes the water in the curved pipe 39 into the vertical cylinder 8, and then the helium enters the water in the vertical cylinder 8. After being washed with water, the helium enters the installation box 61 from the air guide pipe 62, and after the adsorption sponge 67 absorbs water, the activated carbon mesh block 68 absorbs impurities, and then it is output to the external helium storage device through the outlet pipe 63 for storage; When it is necessary to replace the adsorption sponge 67 and the activated carbon mesh block 68, turn off the main power supply, close the valve on the valve connecting pipe 31, turn the fastening bolt 24 to disengage it from the fixing hole 25 set on the upper part, and then pull the disassembly plate 22 downward. The disassembly plate 22 drives the vertical plate 74 to move the support plate 75 downward, and the support plate 75 drives the two second tooth plates 76 to move downward, and the second tooth plates 76 drive the gear roller 73 to make the two first tooth plates 71 move upward synchronously, and the first tooth plate 71 drives the grooved bracket 65 to move upward along the movable notch 69. When the fastening bolt 24 moves to the fixing hole 25 set at the bottom, screw the fastening bolt 24 into the fixing hole 25. At this time, the two grooved brackets 65 drive the activated carbon mesh block 68 and the adsorption sponge 67 to disengage from the movable notch 69, remove the adsorption sponge 67 and the activated carbon mesh block 68, and replace them, and then reset the disassembly plate 22; During the descent of the disassembly and assembly plate 22, the shaped plate 26 is driven to stretch the elastic rope 27 downward, and the elastic rope 27 pulls the L-shaped slider 21 to partially detach it from the connecting square tube 9, so that part of the water in the vertical tube 8 after cleaning with helium flows into the water tank 7. When the disassembly and assembly plate 22 is reset, the inspection door 17 is opened, the filter cylinder 16 is taken out for cleaning, and the filter cylinder 16 is put back. After the inspection door 17 is closed, it can be used again; S3: When the valved connecting pipe 31 is connected to the temporary gas storage tank 1 in S2, the driving motor 18 is started, the driving motor 18 drives the crank shaft 19 to rotate, the crank shaft 19 drives the stirring frame 40 to stir the water in the vertical cylinder 8 to ensure uniform helium water washing, and the crank shaft 19 synchronously drives the driving gear 34 to rotate, the driving gear 34 drives the driving pinion 33 to accelerate the rotation, and the driving pinion 33 drives the spline plug 42 to rotate the reciprocating screw 35; The reciprocating screw 35 drives the isolation plate 36 to drive the plug rod 47 to move the spline column 44 downward, and the isolation plate 36 drives the isolation ring 37 to move downward until the isolation ring 37 blocks the valved connecting pipe 31. At this time, the installation cylinder 30 no longer outputs helium to the curved tube 39. At this time, the crank shaft 19 rotates half a circle, and the crank shaft 19 drives the linkage plate 20 to stretch the elastic rope 27. The elastic rope 27 pulls the L-shaped slider 21 to partially detach it from the connecting square tube 9. During the process, the spring 28 is stretched, and part of the water in the vertical cylinder 8 that has been cleaned by helium flows into the water tank 7 through the connecting square tube 9. At this time, the liquid level in the water tank 7 rises, and when the floating ring 13 squeezes the trigger button 14, the water pump 10 starts to transport the water filtered by the filter cylinder 16 to the vertical cylinder 8 again. As the reciprocating screw 35 continues to rotate, the reciprocating screw 35 drives the isolation plate 36 to drive the plug rod 47 to move the spline column 44 upward, and at the same time the isolation plate 36 drives the isolation ring 37 to move upward until the isolation ring 37 is completely separated from the valved connecting pipe 31. At this time, the installation cylinder 30 continues to output helium to the curved pipe 39. At this time, the crank shaft 19 rotates half a circle again. During the process, the spring 28 is reset, the linkage plate 20 no longer stretches the elastic rope 27, and the L-shaped slider 21 blocks the connecting square pipe 9. The water in the vertical cylinder 8 that has been cleaned with helium no longer flows into the water tank 7. At this time, the liquid level in the water tank 7 drops, and after the floating ring 13 is separated from the trigger button 14, the water pump 10 is turned off; S4: During the rotation of the reciprocating screw 35 in S3, the reciprocating screw 35 drives the cooperative large gear 50 to rotate, the cooperative small gear 51 drives the synchronous small gear 45 to accelerate the rotation, the synchronous small gear 45 drives the spline column 44 to rotate, the spline column 44 drives the synchronous large gear 48 to rotate synchronously through the insertion rod 47, the synchronous large gear 48 drives the cooperative small gear 51 to accelerate the rotation, and the cooperative small gear 51 drives the upper retaining ring 52 to rotate around the positioning ring 55. During the process, the upper retaining ring 52 drives the lower retaining ring 53 to rotate the cleaning disk 54. When the isolation ring 37 completely blocks the valved connecting pipe 31 in S3, the cleaning disk 54 cleans the coarse filter plate 32. When the isolation ring 37 is separated from the valved connecting pipe 31, the pressurized helium to be recovered in the temporary gas storage tank 1 blows the impurities on the coarse filter plate 32 into the dust outlet square pipe 58, and then falls into the storage drawer 60 for storage.

9. A method for using a helium recovery device for helium detection equipment according to claim 8, It is characterized in that The following steps are involved: S1: After turning on the main power supply, water is poured into the water tank (7). As the liquid level rises, the water squeezes the floating ring (13). The floating ring (13) rises along the water inlet pipe (12). When the trigger button (14) is squeezed, the water pump (10) is started. The water pump (10) draws water from the water tank (7) through the water inlet pipe (12) and transports the water to the vertical cylinder (8) through the return pipe (11). The water level in the vertical cylinder (8) continues to rise until the water in the vertical cylinder (8) falls into the curved tube (39). When the water reaches a set height in the curved tube (39), the water is stopped from being poured into the water tank (7). The liquid level in the water tank (7) drops, the trigger button (14) is no longer squeezed, and the water pump (10) is turned off. S2: the pressurized helium to be recovered is stored in a temporary gas storage tank (1). The connecting pipe with a valve (31) is connected to the temporary gas storage tank (1). After the valve is opened, the pressurized helium to be recovered enters the installation cylinder (30) through the connecting pipe with a valve (31). After being coarsely filtered by the coarse filter plate (32), the helium enters the curved pipe (39). The helium squeezes the water in the curved pipe (39) into the vertical cylinder (8). After the helium enters the water in the vertical cylinder (8), it is washed with water and enters the installation box (61) from the air guide pipe (62). After the water is absorbed by the adsorption sponge (67), the impurities are absorbed by the activated carbon mesh block (68), and then the helium is output to the external helium storage device through the gas outlet pipe (63) for storage. S3: When the valved connecting pipe (31) in S2 is connected to the temporary gas storage tank (1), the driving motor (18) is started, the driving motor (18) drives the crank shaft (19) to rotate, the crank shaft (19) drives the stirring frame (40) to stir the water in the vertical cylinder (8) to ensure uniform helium water washing, and the crank shaft (19) synchronously drives the driving gear (34) to rotate, the driving gear (34) drives the driving pinion (33) to accelerate rotation, and the driving pinion (33) drives the spline plug (42) to rotate the reciprocating screw (35); The reciprocating screw (35) drives the isolation plate (36) to drive the plug rod (47) to move the spline column (44) downward, and at the same time, the isolation plate (36) drives the isolation ring (37) to move downward until the isolation ring (37) blocks the valve connecting pipe (31). At this time, the installation cylinder (30) no longer outputs helium to the curved pipe (39). At this time, the crank shaft (19) rotates half a circle, and the crank shaft (19) drives the linkage plate (20) to stretch the elastic rope (27). The elastic rope (27) pulls the L-shaped slider (21) to partially detach it from the connecting square tube (9). During this process, the spring (28) is stretched, and the water in the vertical cylinder (8) that has been cleaned with helium flows into the water tank (7) through the connecting square tube (9). At this time, the liquid level in the water tank (7) rises, and when the floating ring (13) presses the trigger button (14), the water pump (10) starts to transport the water filtered by the filter cylinder (16) to the vertical cylinder (8) again; As the reciprocating screw (35) continues to rotate, the reciprocating screw (35) drives the isolation plate (36) to drive the plug rod (47) to move the spline column (44) upward, and at the same time, the isolation plate (36) drives the isolation ring (37) to move upward until the isolation ring (37) is completely separated from the valve connecting pipe (31). At this time, the installation cylinder (30) continues to output helium to the curved tube (39). At this time, the crank shaft (19) rotates half a circle. During this process, the spring (28) is reset, the linkage plate (20) no longer stretches the elastic rope (27), and the L-shaped slider (21) blocks the connecting square tube (9). The water in the vertical cylinder (8) that has been cleaned with helium no longer flows into the water tank (7). At this time, the liquid level in the water tank (7) drops, and after the floating ring (13) is separated from the trigger button (14), the water pump (10) is turned off; S4: During the rotation of the reciprocating screw (35) in S3, the reciprocating screw (35) drives the cooperating large gear (50) to rotate, the cooperating small gear (51) drives the synchronous small gear (45) to rotate faster, the synchronous small gear (45) drives the spline column (44) to rotate, the spline column (44) drives the synchronous large gear (48) to rotate synchronously through the plug rod (47), the synchronous large gear (48) drives the cooperating small gear (51) to rotate faster, and the cooperating small gear (51) drives the upper retaining ring (52) to rotate around the fixed The positioning ring (55) rotates. During the process, the upper retaining ring (52) drives the lower retaining ring (53) to rotate the cleaning disc (54). When the isolation ring (37) in S3 completely blocks the valved connecting pipe (31), the cleaning disc (54) cleans the coarse filter plate (32). When the isolation ring (37) is separated from the valved connecting pipe (31), the pressurized helium gas to be recovered in the temporary gas storage tank (1) blows the impurities on the coarse filter plate (32) into the dust outlet square pipe (58), and then falls into the storage drawer (60) for storage.

10. A method for using a helium recovery device for helium detection equipment according to claim 9, It is characterized in that When the adsorption sponge (67) and the activated carbon mesh block (68) need to be replaced in S2, the main power supply is turned off, the valve on the valve connecting pipe (31) is closed, the fastening bolt (24) is turned to disengage the fastening bolt (24) from the fixing hole (25) provided on the upper portion, and the disassembly plate (22) is pulled downward, the disassembly plate (22) drives the vertical plate (74) to move the support plate (75) downward, the support plate (75) drives the two second tooth plates (76) to move downward, and the second tooth plates (76) drives the gear roller (73) to move the two first tooth plates (71 ) move upward synchronously, the first tooth plate (71) drives the slotted bracket (65) to move upward along the movable slot (69), and when the fastening bolt (24) moves to the fixing hole (25) set at the bottom, the fastening bolt (24) is screwed into the fixing hole (25), and at this time, the two slotted brackets (65) drive the activated carbon mesh block (68) and the adsorption sponge (67) to separate from the movable slot (69), remove the adsorption sponge (67) and the activated carbon mesh block (68), and replace them, and then reset the disassembly plate (22); During the process of the disassembly and assembly plate (22) descending, the special-shaped plate (26) is driven to stretch the elastic rope (27) downward, and the elastic rope (27) pulls the L-shaped slider (21) so that part of it is separated from the connecting square tube (9), so that part of the water in the vertical cylinder (8) after being cleaned by helium flows into the water tank (7). When the disassembly and assembly plate (22) is reset, the inspection door (17) is opened, the filter cylinder (16) is taken out for cleaning, and the filter cylinder (16) is put back. After the inspection door (17) is closed, it can be used again.
