Description

[0002] The African swine fever test kit is a tool specifically used to detect the presence of African swine fever virus antibodies in pigs. This kit is based on the principle of antigen-antibody reaction and determines whether the pig is infected with African swine fever virus by detecting antibodies in pig serum; the main components of the African swine fever virus antibody test kit include antigen-coated plates, antibody conjugates, enzyme-labeled secondary antibodies, substrate solutions, stop solutions and auxiliary tools.

[0017] Step 3: The pressurized air pump is running, and gas is input into the closed cavity formed by the closed upper bin and the closed lower bin through the input air pipe, so that the air pressure in the closed cavity increases; when the air pressure reaches a certain value, the electric-controlled air valve is closed, and at this time, the African swine fever test kit is deformed inward on all sides under the action of air pressure;

Compared with the visual inspection method of quality inspectors in traditional technology, it can effectively detect some hidden damage problems and improve the control of product quality.

[0022] Through the coordination of structures such as the winding box seat, the slow-release air pipe and the neck scraper ring, after one inspection is completed, the gas pressure between the closed lower bin and the closed upper bin can be utilized before the closed upper bin is controlled to move up and open, thereby reducing the gas pressure, so as to weaken the blowing feeling caused by the instantaneous release of air pressure from the gap between the two when the closed upper bin moves up and opens, thereby reducing the impact on workers and whistling noise; at the same time, the air pressure is utilized to rotate the neck scraper ring through structural transformation. When the neck scraper ring rotates, centrifugal force is generated, and the attached debris scraped off the lifting spindle is thrown to the surroundings through the centrifugal force, thereby reducing the accumulation of debris on the neck scraper ring.

[0044] A detection method of a closed detection device for African swine fever test kit detection, the method comprising the following steps:

[0045] Step 1: Place the African swine fever test kit in the test kit positioning slot 5;

[0046] Step 2: Control the closed upper chamber 3 to move downward, so that the closed upper chamber 3 cooperates with the closed lower chamber 2 to form a closed cavity, and the reagent kit positioning groove 5 is located in the closed cavity;

[0047] Step 3: The pressurized air pump 8 is running, and gas is input into the closed cavity formed by the closed upper bin 3 and the closed lower bin 2 through the input air pipe 11, so that the air pressure in the closed cavity increases; when the air pressure reaches a certain value, the electric control air valve 9 is closed, and at this time, each surface of the African swine fever test kit is deformed inward under the action of air pressure;

[0048] Step 4: Control the pressure sensing head 6 to move downward, press against the top surface of the African swine fever test kit, and then stop moving downward and remain motionless;

[0049] Step 5: Monitor and analyze the extrusion pressure value through the pressure sensor 601. When there is a sealing leakage on the surface sealing film of the African swine fever test kit, the pressure inside and outside the African swine fever test kit will gradually balance, so that the inwardly deformed surfaces of the African swine fever test kit will gradually recover, thereby increasing the pressure value monitored by the pressure sensor 601, thereby achieving detection.

[0050] The sealing detection device of the present invention is used as follows Figure 5 As shown in , the African swine fever test kit is placed in the test kit positioning groove 5 for positioning, so that the closed upper bin 3 moves downward and seals with the closed lower bin 2 to form a closed cavity.

[0051] like Figure 1 and Figure 2 As shown in the figure, the pressurized air pump 8 runs to generate pressurized gas, which is input into the closed cavity formed by the closed upper bin 3 and the closed lower bin 2 through the input air pipe 11; at this time, the air pressure in the closed cavity gradually increases, and the pressure value is monitored by the air pressure sensor 10. When a certain value is reached, the pressurized air pump 8 is turned off, and the electric-controlled air valve 9 is closed to cut off the connection.

[0052] Since the external air pressure of the African swine fever test kit is relatively high, each surface of the African swine fever test kit is concave inward under the pressure of the air pressure. The lifting spindle 7 is controlled to move downward, driving the pressure sensing head 6 to move downward, so that the pressure sensing head 6 contacts the top surface of the African swine fever test kit. When multiple pressure sensing heads 6 are all in contact with their corresponding African swine fever test kits, the lifting spindle 7 is stopped from moving downward and the position is fixed. The pressure between the pressure sensing head 6 and the branch arm 602 is detected by the pressure sensor 601.

[0053] There are two situations at this time. When the sealing film on the surface of the African swine fever test kit is not damaged, the pressure value detected by the pressure sensor 601 is in a stable state. When the sealing film on the surface of the African swine fever test kit is damaged, due to the damage of the sealing film, the high-pressure gas in the closed cavity formed by the closed upper bin 3 and the closed lower bin 2 will enter the African swine fever test kit through the damaged point, so that the air pressure inside and outside the African swine fever test kit gradually balances. In this gradual balance process, the concave surfaces of the African swine fever test kit gradually recover elastically, and the squeezing force on the pressure sensing head 6 gradually increases, so that the detection value of the pressure sensor 601 gradually increases, thereby judging that the sealing film of the African swine fever test kit is damaged.

[0054] After completing a test, if Figure 8 As shown in the figure, the telescopic plug shaft 315 is retracted by controlling the electromagnetic telescope 314 to release the limit on the traction piston 312; since the slow-release air pipe 311 is connected to the inner cavity of the closed upper warehouse 3 through the winding box seat 308, when the traction piston 312 loses the limit, the high-pressure gas in the closed cavity formed by the closed upper warehouse 3 and the closed lower warehouse 2 will push the traction piston 312 to quickly move in the direction away from the winding box seat 308.

[0055] When the traction piston 312 moves, the traction rope 313 is used to pull the winding wheel 310 to rotate, thereby causing the transmission optical axis 307 and the driving worm 306 to rotate. At this time, the spring reset spring 309 elastically stores force.

[0056] like Fig.10 As shown in , during the downward movement of the lifting spindle 7, the oil, gravel, dust and other debris adhered to the surface of the lifting spindle 7 will be scraped and cleaned by the neck scraper ring 303, thereby improving the protection effect of the lifting spindle 7 and preventing the debris from being brought between the sealing ring sleeve 301 and the lifting spindle 7, thereby affecting the gas sealing between the two. The cleaned oil and debris are accumulated on the neck scraper ring 303. At this time, the worm 306 is driven to rotate, and the worm gear ring 305 is driven to rotate, so that the neck scraper ring 303 and the rotating ring 302 rotate accordingly. When the neck scraper ring 303 rotates, centrifugal force is generated, and the scraped attached debris is thrown to the surroundings by the centrifugal force, thereby reducing the accumulation of debris on the neck scraper ring 303.

[0057] At the same time, since the high-pressure gas in the closed cavity formed by the closed upper warehouse 3 and the closed lower warehouse 2 enters the slow-release air pipe 311 to drive the traction piston 312 to move, the air pressure in the closed cavity will be reduced; when the closed upper warehouse 3 moves up and opens, the airflow purge and whistling noise can be effectively reduced.

[0058] When the closed upper chamber 3 moves upward, the air pressure in the closed cavity disappears, and the spring reset spring 309 drives the transmission optical axis 307 and the winding wheel 310 to reverse through elastic force, so that the traction piston 312 is reset.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
