Description

Technical Field

[0001] The present invention relates to the technical field of virus detection, and in particular to a virus detection device. Background Art

[0002] African swine fever is an acute, hemorrhagic, highly contagious disease caused by the African swine fever virus infecting domestic pigs and various wild boars (such as African wild boars, European wild boars, etc.). In order to prevent the spread of African swine fever virus, farms usually select biological samples collected from domestic pigs and send them to professional virus testing sites for testing. After the samples are processed by virus testers, the processed viral nucleoside is obtained and added to the PCR tube containing the reaction solution, and then the PCR tube is placed in the PCR detector to confirm the presence of the virus by amplifying and analyzing the viral nucleic acid.

[0003] The heating element is the core component of the PCR detector for heating. During the long-term use of the PCR detector, its heating element and temperature sensor will face aging and damage problems. At this time, the PCR detector will have abnormal heating. At this time, the temperature sensor cannot feedback the temperature of the heating element, resulting in the PCR detector being unable to accurately control the temperature, thereby damaging the virus sample being tested and being damaged by excessive heating. For this reason, we propose a virus detection device. Summary of the invention

[0004] The main purpose of the present invention is to provide a virus detection device. The present invention arranges a temperature release mechanism on the box wall of the PCR detector body and its matching inspection platform. The temperature release mechanism sets an air-inducing and heat-dissipating position at the inspection platform of the PCR detector body. At the same time, a temperature sensor is installed in the PCR detector body as a backup temperature detection means. After the temperature measuring element of the PCR detector body is aged and damaged, the PCR detector body can detect its own temperature rise abnormality with the help of the temperature sensor. Then, the temperature release mechanism can introduce air into the PCR detector body through the fan and then lead it out to the outside, thereby ensuring that the virus sample being detected will not be damaged when the PCR detector body has a temperature rise abnormality, which can effectively solve the problems in the background technology.

[0035] The semicircular heat grooves 4 are symmetrically opened in two groups on the side wall surface of the inspection table 2, and the edge of the inspection table 2 is penetrated by the hole groove of the connecting groove 5, and the groove cavity of the connecting groove 5 is opened with a connecting groove hole position at the groove cavity of the semicircular heat groove 4;

[0038] By adopting the above preferred technical solution, the air plate 17 has multiple groups of air grooves 18 on its surface, which can reduce the size of the outer seat opening 16 while leaving a small amount of air circulation space, thereby improving the air circulation of the side row seat 12 and the side guide seat 13.

[0039] Wherein, the remaining seat size of the gas plate 17 after welding at the outer seat 16 is smaller than the shell size of the exhaust fan 14 and the induced draft fan 15;

[0040] By adopting the above preferred technical solution, after the outer seat opening 16 is welded to the air plate 17, the exhaust fan 14 and the induced draft fan 15 are respectively fastened by bolts at the side row seat 12 and the side guide seat 13, and the exhaust fan 14 and the induced draft fan 15 can better cover the outer seat opening 16.

[0041] The hole cavity of the side mounting hole 6 is a threaded hole cavity, and the threaded hole cavity of the side mounting hole 6 is screwed into the external threaded shell of the rotary shell 8, and the external threaded shell of the rotary shell 8 is interference fit outside the shell of the temperature sensor 7;

[0042] By adopting the above-mentioned preferred technical solution, after the outer shell of the temperature sensor 7 is clamped with the screw shell 8, the temperature sensor 7 can be tightly screwed and installed at the threaded hole cavity of the side mounting hole 6 with the help of the screw shell 8 of the external threaded shell, so that the temperature measuring head of the temperature sensor 7 can be extended into the PCR detector body 1 to detect the temperature.

[0043] The temperature sensor 7 is provided with a tail seal ring 9 on the outer sleeve of the housing near the rear of the rotating housing 8, and the elastic ring of the tail seal ring 9 is closely blocked at the outer opening of the side mounting hole 6;

[0044] By adopting the above preferred technical solution, after the temperature sensor 7 is screwed to the side mounting hole 6 by means of the screw shell 8, the tail sealing ring 9 can be sealed outside the side mounting hole 6 to prevent foreign matter from entering between the side mounting hole 6 and the screw shell 8.

[0045] The upper connecting plate 21 is welded with a stud rod 23 in the center of the upper plate surface away from the plug-in sealing plate 20, and the stud rod 23 is screwed upward into the telescopic rod head of the electric push rod 22;

[0046] By adopting the above preferred technical solution, after the upper connecting plate 21 is welded with the stud rod 23, the stud rod 23 is screwed into the telescopic rod head of the electric push rod 22 for connection, so that the electric push rod 22 can be lifted and lowered with the plug-in sealing plate 20 through the upper connecting plate 21.

[0047] The plate body size of the plug-in sealing plate 20 is larger than the cavity size of the side discharge port 10 and the side lead-in port 11, and the plug-in sealing plate 20 is closely attached to the outer wall of the PCR detector body 1;

[0048] By adopting the above preferred technical solution, the plug-in sealing plate 20 can block the side discharge port 10 and the side inlet 11 over a large area.

[0049] The sealing plate 20 has a rubber sheet bonded to the outer side of the plate facing the PCR detector body 1, and the sealing plate 20 presses the rubber sheet against the box wall of the PCR detector body 1;

[0050] By adopting the above preferred technical solution, when the sealing plate 20 is attached to the box wall of the PCR detector body 1 with the side provided with the rubber plate, the side discharge port 10 and the side inlet port 11 can be tightly sealed.

[0051] It should be noted that the present invention is a virus detection device. The present invention sets a temperature relief mechanism 3 on the box wall of the PCR detector body 1 and its matching inspection table 2. After the electric push rod 22 of the temperature relief mechanism 3 is installed on the surface of the PCR detector body 1, it can be connected to the control element of the PCR detector body 1 through an external controller or an additional controller for signal control. After the temperature sensor 7 is installed at the side mounting hole 6 of the PCR detector body 1 with the help of a rotating shell 8, the temperature sensor 7 can be connected to the control element of the PCR detector body 1, and the temperature sensor 7 of the temperature relief mechanism 3 is used as a spare temperature measuring end of the PCR detector body 1.

[0052] After a PCR test tube containing an African swine fever virus sample is placed on the inspection table 2 of the PCR detector body 1, the inspection table 2 can bring the PCR test tube into the PCR detector body 1, and then the PCR detector body 1 turns on the detection system to increase the temperature, the electric push rod 22 can be controlled to extend the telescopic rod downward, and the upper connecting plate 21 below the telescopic rod head presses the plug-in sealing plate 20 to be inserted into the side row seat 12 and the side guide seat 13 from the vertical slot 19, and the plug-in sealing plate 20 is attached to the box wall of the PCR detector body 1 with a side provided with a rubber plate, so that the side row port 10 and the side guide port 11 are tightly blocked, and then the PCR detector body 1 can normally increase and decrease the temperature for virus detection, and the temperature data in the PCR detector body 1 measured by the temperature sensor 7 of the temperature release mechanism 3 can be used as a comparison reference for the temperature measurement data of the original temperature measurement element of the PCR detector body 1. If the PCR detector body 1 is normal, the temperature measurement data will not have a large deviation. At this time, the virus is detected normally in the PCR detector body 1, and the virus detection data is obtained;

[0053] If the temperature measuring element in the PCR detector body 1 is damaged due to aging, the temperature obtained by the temperature sensor 7 and the temperature obtained by the temperature measuring element have too large a deviation value, at this time, the electric push rod 22 can pull the plug-in sealing plate 20 up to leave the vertical slot 19, and then the exhaust fan 14 and the induced draft fan 15 are powered on, and the induced draft fan 15 blows wind into the side inlet 11 at the outer seat opening 16 of the side guide seat 13. When the wind enters the PCR detector body 1 from the side inlet 11, the wind can flow between the detection table 2 and the PCR detector body 1 from the semicircular heat groove 4 and the connecting groove 5, and the circulated air can enter the side outlet 10 and enter the side row seat 12, while the exhaust fan 14 draws air outward at the side row seat 12, which assists the rapid heat release and heat dissipation inside the PCR detector body 1, and avoids the problem of sample temperature rise and damage caused by the aging of the temperature measuring element of the PCR detector body 1 of the virus sample being detected;

[0054] Furthermore, when the PCR detector body 1 needs to cool down the virus sample, the side exhaust port 10 and the side inlet port 11 can be controlled to open, and the exhaust fan 14 and the induced draft fan 15 can be used to quickly remove the heat in the PCR detector body 1 for rapid cooling. The temperature sensor 7 is installed on the outside of the PCR detector body 1 and can be replaced and maintained regularly, thereby ensuring the safety of the temperature sensor 7 and preventing the PCR detector body 1 from suffering from abnormal temperature rise caused by damage to the temperature measuring element.
