At the same time, the third clamping block is always clamped on the surface of the incubation cylinder under the elastic force of the return spring to avoid the shaking of the incubation cylinder. When the deformation is large, the control terminal drives the cross beam to move, and then drives the second clamping block and the third clamping block to move, maintaining a constant and flexible clamping force to avoid stress concentration or extrusion rupture caused by fixed card slots;

[0023] 2. By arranging multiple electric heating modules evenly distributed within the support platform, the heat is directly transferred to the water body in the water tank. Combining with the diversion holes opened on the surface of the incubation spacer frame, rapid and uniform distribution of the water temperature within the incubation spacer frame is achieved. By setting two pushing blocks to adjust the lifting platform, and then adjusting the height at which the incubation cylinder is placed, no matter how many samples are in the incubation cylinder, the water surface in the water tank is always higher than the sample surface, enabling the incubation cylinder to be heated more evenly and comprehensively, eliminating the reaction efficiency differences caused by local temperature differences in traditional devices.

[0036] Referring to Figures 1-8 , a detection sample incubation device, including a base 1, a protective enclosure 3 is fixedly installed around the top of the base 1, and further includes: a water tank 8, the water tank 8 is fixedly installed in the middle of the top of the base 1, a heat preservation enclosure 10 is fixedly installed around the outside of the water tank 8, and a plurality of incubation partition frames 801 are linearly arranged in the water tank 8, and a plurality of diversion holes 802 penetrating through its outer surface are opened on both sides of each incubation partition frame 801;

[0037] The clamping assembly 9, the clamping assembly 9 includes a cross beam 901, a first clamping block 902, a second clamping block 903 and a third clamping block 904. There are multiple first clamping blocks 902, second clamping blocks 903 and third clamping blocks 904. One side of the first clamping block 902, the second clamping block 903 and the third clamping block 904 is of a V-shaped structure. The multiple first clamping blocks 902 are respectively fixedly installed on one side of the top of multiple incubation spacer frames 801. The V-shaped openings of the multiple second clamping blocks 903 and the third clamping blocks 904 face the first clamping block 902 and are opposite to the V-shaped opening of the first clamping block 902. The second clamping block 903 and the third clamping block 904 are both slidably installed on the top of the corresponding incubation spacer frame 801. On the other side of the third clamping block 904, two convex shafts 905 are symmetrically arranged. One end of each convex shaft 905 passes through the second clamping block 903 and a return spring 906 is fixedly installed at the end. Multiple pressure sensors 908 are fixedly embedded on the surface of the cross beam 901. One end of each return spring 906 is fixedly installed with the detection end of the pressure sensor 908. Multiple adjusting screw rods 909 for adjusting the second clamping block 903 are arranged on the surface of the cross beam 901. In the present invention, by setting the clamping assembly 9, one side of the first clamping block 902, the second clamping block 903 and the third clamping block 904 is designed in a V-shaped structure. Combining the return spring 906 and the pressure sensor 908, the clamping force can be dynamically adjusted according to the real-time deformation of the incubation cylinder. When the incubation cylinder expands or contracts due to temperature changes, the pressure sensor 908 feeds back data in real time. At the same time, the third clamping block 904 is always clamped on the surface of the incubation cylinder under the elastic force of the return spring 906 to prevent the incubation cylinder from shaking. When the deformation is large, the control terminal drives the cross beam 901 to move, thereby driving the second clamping block 903 and the third clamping block 904 to move, maintaining a constant and flexible clamping force, and avoiding stress concentration or extrusion rupture caused by the fixed clamping groove.

[0038] In this embodiment, two sliding holes 907 adapted to the convex shafts 905 are opened on the surface of the second clamping block 903. The two convex shafts 905 are respectively slidably connected to the two sliding holes 907. One end of each of the multiple adjusting screw rods 909 passes through the outer surface of the cross beam 901 and is threadedly connected thereto. One end of each adjusting screw rod 909 is rotatably installed on one side of the corresponding second clamping block 903. A knob 910 is fixedly installed at the other end of each adjusting screw rod 909. The cross beam 901 is slidably installed on the top of the heat preservation enclosure 10. Multiple scale marks 911 are linearly and uniformly fixedly installed on the top of the cross beam 901. Above each scale mark 911, a pointer 912 is provided. Each pointer 912 is fixedly installed on the top of the cross beam 901. Each scale mark 911 is fixedly installed on one side of the corresponding second clamping block 903.

[0039] During use, turning the knob 910 drives the adjusting screw 909 to rotate, thereby adjusting the distance between the second clamping block 903 and the cross beam 901, realizing fine adjustment of the local clamping assembly 9, making the applicable range of the device wider, and enabling the incubation cylinder to be clamped with more precise force; setting the scale 911 can clearly and intuitively show the adjustment situation of the second clamping block 903, facilitating the unity of adjustment.

[0040] In this embodiment, a guide shaft 11 is fixedly installed on one side of the top of the heat preservation enclosure 10, and a first lead screw 12 is rotatably installed on the other side of the top of the heat preservation enclosure 10. One end of the first lead screw 12 passes through a plurality of cross beams 901 and is threadedly connected thereto. The plurality of cross beams 901 are all slidably sleeved on the surface of the guide shaft 11. A first motor 13 is fixedly installed on one side of the heat preservation enclosure 10. The output end of the first motor 13 is fixedly installed at the rotation center of one end of the first lead screw 12. Avoidance grooves 1001 are formed on both opposite sides of the heat preservation enclosure 10. Two push blocks 18 are symmetrically arranged in the two avoidance grooves 1001. The two push blocks 18 are both slidably installed on the top of the base 1. Each push block 18 has a right trapezoidal structure. A scale line 1801 is formed on one side of each push block 18. A bidirectional motor 16 is fixedly installed on the top of the base 1. Two second lead screws 15 are symmetrically rotatably installed on the top of the base 1. The two output ends of the bidirectional motor 16 are respectively fixedly installed at the rotation centers of the ends of the two second lead screws 15.

[0041] During use, driving the first lead screw 12 to rotate by the first motor 13 can drive a plurality of cross beams 901 to be slidably installed on the surface of the guide shaft 11, thereby synchronously driving a plurality of clamping assemblies 9 to clamp the incubation cylinder, with high working efficiency; by operating the bidirectional motor 16, driving the two second lead screws 15 to rotate, the two second lead screws 15 threadedly drive the two connecting rods 17, thereby driving the two push blocks 18 to move towards each other synchronously, thereby adjusting the height of the lifting platform 19 until the water surface in the water tank 8 exceeds the height of the sample. Setting the scale line 1801 can visually judge the adjustment situation of the lifting platform 19 through the protective enclosure 3 and the top cover 4, facilitating the operator to judge whether the program adjustment is correct and improving the operation accuracy of the equipment.

[0042] In this embodiment, a connecting rod 17 is threadedly sleeved on the surface of each second lead screw 15. One ends of two connecting rods 17 are respectively fixedly installed with two pushing blocks 18. An elevating platform 19 is arranged on the inclined surfaces of the two pushing blocks 18. A plurality of supporting platforms 1902 are arranged in an array on the top of the elevating platform 19. A plurality of square slot holes 1901 are formed at the bottom of the elevating platform 19. The bottom of each supporting platform 1902 is of an open structure. An electric heating module 21 is fixedly installed in each supporting platform 1902. Each supporting platform 1902 is slidably fitted in a corresponding incubation spacer frame 801. A plurality of straight water pipes 20 are fixedly installed at the bottom of the water tank 8. A water inlet pipe 5 and a water outlet pipe 6 are symmetrically and fixedly installed in the base 1. One end of the water inlet pipe 5 is communicated with a plurality of straight water pipes 20 on the same side. One end of the water outlet pipe 6 is communicated with a plurality of straight water pipes 20 on the other side. Valves 7 are fixedly installed at the other ends of the water inlet pipe 5 and the water outlet pipe 6. A control terminal 2 is fixedly installed on one side of the protective enclosure 3. A top cover 4 is hinged to the top of the protective enclosure 3. Both the top cover 4 and the protective enclosure 3 are made of transparent materials. An inspection opening for maintaining the two-way motor 16 is formed on one side of the protective enclosure 3. An inspection door 14 is detachably and fixedly installed in the inspection opening.

[0043] During use, by arranging a plurality of electric heating modules 21 evenly distributed in the supporting platforms 1902, the heat is directly transferred to the water body in the water tank 8. Combining with the diversion holes 802 formed on the surface of the incubation spacer frame 801, the rapid and uniform distribution of the water temperature in the incubation spacer frame 801 is realized. By arranging two pushing blocks 18 to adjust the elevating platform 19, and then adjusting the placement height of the incubation cylinder, no matter how many samples are in the incubation cylinder, the water surface in the water tank 8 is always higher than the sample surface, so that the incubation cylinder can be heated more evenly and comprehensively, eliminating the reaction efficiency difference caused by local temperature difference in the traditional device.

[0044] The water inlet pipe 5 is communicated with an external water supply device, and the water outlet pipe 6 is communicated with an external waste water collection device. Arranging the elevating platform 19 can adjust the placement height of the incubation cylinder, and can also move slightly up and down before the height of the incubation cylinder is adjusted in place, thereby driving the samples in the incubation cylinder to vibrate, which is beneficial to the rapid reaction after the water temperature is heated and improves the working efficiency of incubation.

[0045] A method for using a sample incubation device for detection includes the following steps:

[0046] S1: When in use, open the top cover 4, then place a plurality of incubation cylinders containing samples on the tops of the supporting platforms 1902 in the corresponding incubation spacer frames 801 respectively, and then cover the top cover 4.

[0047] S2: According to the height of the sample in the incubation cylinder, drive the bidirectional motor 16 to operate through the control terminal 2, drive the two second lead screws 15 to rotate, the two second lead screws 15 thread-drive the two connecting rods, and then drive the two pushing blocks 18 to move synchronously towards each other, thereby adjusting the height of the lifting platform 19 until the water surface in the water tank 8 exceeds the height of the sample;

[0048] S3: Start the first motor 13 to drive the first lead screw 12 to rotate. The first lead screw 12 simultaneously drives multiple cross beams 901 to move, drives the second clamping block 903 and the third clamping block 904 to slide towards the incubation cylinder until the pressure sensor feeds back a suitable pressure value, then stop the first motor 13, and select different pressure values according to the material of the incubation cylinder;

[0049] S4: Through the control terminal 2, start multiple electric heating modules 21 to work. The heat is transferred to the water in the water tank 8 through the support platform 1902. Through multi-point heating, the water in the water tank 8 is evenly heated, and then the incubation cylinder is heated evenly.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
