DETAILED DESCRIPTION
[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0015] Embodiment 1, an improved capillary frozen semen fumigation box, comprising Figure 1-3 The invention provides a box body 1, wherein the four corners of the inner wall of the box body 1 are provided with liquid level observation components 2; the liquid level observation component 2 comprises a mounting block 201, a rectangular groove 202 is provided on the side wall of the mounting block 201, a glass plate 203 is provided inside the rectangular groove 202, a mounting groove 204 is provided inside the mounting block 201, the mounting groove 204 is connected with the rectangular groove 202, a lamp bead 205 is provided inside the mounting groove 204, the glass plate 203 is used to facilitate the light emitted by the lamp bead 205 to pass out, the glass plate 203 and the lamp bead 205 cooperate to form a light scale line, a fixing component 3 is provided on the top of the mounting block 201, and the glass plate 203 The material is set to quartz glass, which can withstand the low temperature environment of liquid nitrogen. The lamp bead 205 emits yellow light after being energized, which has a color difference with the white smoke generated after the liquid nitrogen is poured in. The shape of the mounting block 201 is set to an isosceles right triangle, so that when the mounting block 201 is installed, the two right-angled sides are in contact with the two inner walls of the box body 1, and the glass plate 203 is set on the hypotenuse of the mounting block 201. The yellow light emitted by the lamp bead 205 passes through the glass plate 203 to the inside of the box body 1, thereby forming a yellow scale line. The yellow scale line forms a color difference with the white smoke, which is convenient for observation. At the same time, the mounting block 201 is installed at the four corners of the box body 1 to facilitate the control of the liquid level.
[0016] Embodiment 2, based on embodiment 1, Figure 4It is given that the fixing assembly 3 includes two fixing plates 301 symmetrically installed on the top of the mounting block 201, the two fixing plates 301 are respectively parallel to the two right-angled sides of the mounting block 201, a suction cup 302 is fixedly installed on the side of the fixing plate 301 close to the inner wall of the box body 1, and the end face of the suction cup 302 is tightly attached to the inner wall of the box body 1, and a fixing cylinder 303 is fixedly installed on the side of the fixing plate 301 away from the suction cup 302, the fixing cylinder 303 is connected to the suction cup 302, and an air pressure balance hole 304 is opened at one end of the fixing cylinder 303 at an equal angle, a screw cylinder 305 is installed at one end of the fixing cylinder 303, a piston 306 is movably installed inside the fixing cylinder 303, the outer wall of the piston 306 is tightly attached to the inner wall of the fixing cylinder 303, and the piston 306 is away from the suction cup 302. A screw rod 307 is fixedly installed on one side, and the screw rod 307 is threadedly connected to the screw barrel 305. Two fixing plates 301 are arranged on the top of the mounting block 201. The suction cup 302 on the fixing plate 301 is in close contact with the inner wall of the box body 1. The movement of the piston 306 generates a negative pressure between the suction cup 302 and the inner wall of the box body 1, thereby completing the fixation, thereby facilitating the disassembly and assembly of the mounting block 201 and facilitating the adjustment of the scale line height. A negative pressure is formed between the suction cup 302 and the box body 1. When liquid nitrogen is poured into the box body 1, the ambient temperature drops, so that the air between the suction cup 302 and the box body 1 contracts due to the drop in temperature, thereby increasing the negative pressure between the suction cup 302 and the box body 1, improving the fixing stability of the mounting block 201, and improving the control accuracy of the liquid level.
[0017] Working principle: When working, the lamp bead 205 emits yellow light after being lit, and the yellow light passes through the glass plate 203 to the inside of the box 1, so that the glass plate 203 forms a yellow illumination scale line. When liquid nitrogen is poured into the box 1, white smoke is generated. Since there is a color difference between the yellow illumination scale line and the white smoke, it is convenient for the staff to control the liquid level of the liquid nitrogen, and the mounting block 201 is set at the four corners of the box 1 to improve the observation effect; when installing, the two right-angled sides of the mounting block 201 are respectively in contact with the two inner walls of the box 1, so that the suction cup 302 is tightly attached to the inner wall of the box 1, and then the screw 307 is screwed. 7 is threadedly connected with the screw barrel 305, thereby driving the piston 306 to move toward the side away from the suction cup 302, so that negative pressure is generated between the suction cup 302 and the inner wall, thereby completing the adsorption fixation, facilitating the disassembly and assembly of the mounting block 201, and facilitating the adjustment of the scale line height and the maintenance of the equipment; at the same time, after the piston 306 moves, the air pressure inside the suction cup 302 decreases. When liquid nitrogen is poured in, the temperature drops. At this time, the air temperature inside the suction cup 302 drops and then contracts, so that the negative pressure increases, thereby improving the fixing stability of the mounting block 201, preventing the mounting block 201 from loosening due to the impact of the generated white smoke, and improving the control accuracy of the liquid level.
