The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0043] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0044] like Figure 1 and Figure 2 , Figure 3 As shown, a biological microscopic analysis device in an embodiment of the present invention includes a biological counting frame 1, a microscopic observation component 2 and a component extraction component 3; the biological counting frame 1 includes a main frame plate 11 and a plurality of quantitative units 12 arranged on the main frame plate 11, and the quantitative unit 12 includes a dilution amount frame 121 and a quantitative circular frame 122; the microscopic observation component 2 includes a digital microscopic head 21, a display screen 22 and a controller electrically connected to the digital microscopic head 21 and the display screen 22, respectively, and the quantitative circular frame 122 is arranged below the digital microscopic head 21; the component extraction component 3 includes an extraction component 31 and a driving component 32, the extraction component 31 includes an extraction tube 33 and a pressing unit 34, the extraction tube 33 is provided with a plurality of quantitative cavities 331 extending vertically, the quantitative cavity 331 is provided with a quantitative port 332 at the bottom and a pressing port 333 at the top; the pressing unit 34 includes a plurality of pressing groups 341 respectively used to press a single pressing port 333. Specifically, the bottom of the extraction tube 33 is a circular tube opening adapted to fit the quantitative circular frame 122 .

[0045] The above-mentioned biological microscopic analysis device drives the extraction component 31 to move through the driving component 32, and the extraction component 31 extracts the plankton in the dilution amount frame 121 to different quantitative circular frames 122; the digital microscope head 21 takes a microscopic picture of the plankton in the dilution amount frame 121 and transmits it to the controller for visual recognition and counting the number, and the component extraction component 3 extracts the plankton in the dilution amount frame 121 to different quantitative circular frames 122 to calculate the plankton specimen quantity. In this way, the number of plankton is directly displayed on the display screen 22 through the microscopic observation component 2, and when the multiple quantitative ports 332 evenly arranged in a circle are inserted into the dilution solution in the dilution amount frame 121, the pressing port 333 is pressed by the pressing group 341 to transfer the dilution solution, and the same amount of solution is extracted by releasing different pressing ports 333, which saves time and effort; at the same time, due to the method of separating the inside of the dilution amount frame 121 along the circumference, when dripping the solution, the number of plankton is small and uniform.

[0046] In one embodiment, the inside of the extraction tube 33 is divided into four quantitative chambers 331 by a cross-component partition. In this way, the four quantitative chambers 331 in the extraction tube 33 divide the solution into four parts each time the solution is extracted by droplets. When the dilution amount frame 121 has been diluted to a predetermined quantity range, the four quantitative chambers 331 can meet the quantity requirements of daily experiments; moreover, the cross-component partition has a reasonable structure, is less difficult to produce and process, and is convenient for reducing production costs.

[0047] In one embodiment, the pressing unit 34 includes four pressing groups 341, and the pressing group 341 includes an electric push rod 342 and a pressing block 343 driven by the electric push rod 342, and the pressing block 343 is adapted to the pressing port 333. In this way, the electric push rod 342 is used to drive the pressing block 343, the structure is simple, the reaction speed and control speed of the electric push rod 342 are relatively fast, the solution dripping action and the liquid discharge action are convenient, and the work efficiency is improved.

[0048] In one embodiment, the pressing port 333 is provided with a truncated cone-shaped opening, and the pressing block 343 is a circular sealing block. Specifically, a circular flange rubber ring is provided on the outer circumference of the circular sealing block, and the pressing port 333 is provided with a circular concave limiting groove adapted to the circular flange rubber ring, and the elastic deformation capacity of the circular flange rubber ring is greater than the elastic deformation capacity of the circular sealing block. In this way, when the quantitative port 332 is inserted into the diluted solution, the truncated cone-shaped opening can guide the electric push rod 342 to drive the pressing block 343 to enter accurately, so that the circular flange rubber ring is engaged in the circular concave limiting groove, and the pressing port 333 is sealed, so that the quantitative cavity 331 is separated from the outside air. By using the pressure difference, when the extraction tube 33 moves, the solution at the quantitative port 332 moves with it without falling, thereby completing the dripping action.

[0049] like Figure 1 and Figure 4 As shown, in one embodiment, the driving assembly 32 includes a first driving unit 35 and a second driving unit 36, the first driving unit 35 includes a first mounting seat 351, a first driving motor 352 disposed on the first mounting seat 351, a first driving screw 353 driven by the first driving motor 352, and a first screw seat 354 connected to the first driving screw 353, and the extraction assembly 31 is disposed on the first screw seat 354; the second driving unit 36 ​​includes a second mounting seat 361, a second driving motor 362 disposed on the second mounting seat 361, a second driving screw 363 driven by the second driving motor 362, and a second screw seat 364 connected to the second driving screw 363, and the first mounting seat 351 is disposed on the second screw seat 364. Specifically, the first driving screw 353 and the second driving screw 363 are vertically disposed, the center line of the first driving screw 353 is disposed along the vertical Z direction, and the center line of the second driving screw 363 is disposed along the horizontal Y direction. In this way, the motor is used to drive the screw to rotate, which drives the screw seat to move, so that the extraction component 31 can move in two dimensional directions.

[0050] In one embodiment, the driving assembly 32 further includes a third driving unit 37, the third driving unit 37 includes a third mounting seat 371, a third driving motor 372 arranged on the third mounting seat 371, a third driving screw rod 373 driven by the third driving motor 372, and a third screw rod seat 374 connected to the third driving screw rod 373 by transmission, and the main frame plate 11 is arranged on the third screw rod seat 374. Specifically, the center line of the third driving screw rod 373 is arranged along the horizontal X direction. In this way, the motor is used to drive the screw rod to rotate, driving the screw rod seat to move, so that the extraction assembly 31 can be moved in three dimensional directions relative to the main frame plate 11.

[0051] In one embodiment, the biological placement component 4 is also included, and the driving assembly 32 also includes a fourth driving unit 38 and a clamping unit 39 disposed on the fourth driving unit 38; the biological placement component 4 includes a placement bracket 41 and a placement tube seat 42, and a plurality of placement positions are provided on the placement tube seat 42. Specifically, the structure of the fourth driving unit 38 is the same as that of the first driving unit 35. In this way, the second driving unit 36 ​​and the fourth driving unit 38 are used to drive the clamping unit 39 to move in the horizontal Y direction and the vertical Z direction respectively, so that the clamping unit 39 can clamp the quantitative circular frame 122 and place the quantitative circular frame 122 on the placement position of the placement tube seat 42.

[0052] like Figure 1 and Figure 4 , Figure 6 , Figure 7As shown, in one embodiment, the clamping unit 39 includes a clamping seat 391, a clamping motor 392 arranged on the clamping seat 391, a gear set 393 driven by the clamping motor 392, and a clamping arm set 394 transmission connected to the gear set 393; the gear set 393 includes a first gear 395 connected to the output shaft hub of the clamping motor 392, and a second gear 396 transmission connected to the first gear 395; the clamping arm set 394 includes a first clamping arm 397 connected to the hub of the first gear 395, and a second clamping arm 398 connected to the hub of the second gear 396. In this way, the gear group 393 is driven to rotate by the clamping motor 392, driving the clamping ends of the first clamping arm 397 and the second clamping arm 398 of the clamping arm group 394 to move away from or closer to each other, thereby realizing the clamping action of the clamping arm group 394 on the quantitative circular frame 122, making it convenient for the second driving unit 36 ​​and the fourth driving unit 38 to drive the clamping unit 39 to move stably in the horizontal Y direction and the vertical Z direction respectively.

[0053] In one embodiment, the clamping unit 39 also includes a first connection group 3901 connecting the clamping seat 391 and the first clamping arm 397, and a second connection group 3902 connecting the clamping seat 391 and the second clamping arm 398; the first connection group 3901 includes a first connecting rod and a second connecting rod; one end of the first connecting rod is hinged to the clamping seat 391, and the other end is hinged to the second connecting rod; one end of the second connecting rod is hinged to the first connecting rod, and the other end is hinged to the first clamping arm 397; a groove is provided at the contact point between the first clamping arm 397 and the second clamping arm 398 and the quantitative circular frame 122. Specifically, an elastic contact ring is sleeved on the outer side of the quantitative circular frame 122. In this way, when the first clamping arm 397 and the second clamping arm 398 are used to clamp the quantitative circular frame 122, the elastic contact ring deforms and fills the groove, so that the quantitative circular frame 122 can be clamped and positioned relative to the clamping arm group 394; at the same time, the contact friction between the elastic contact ring and the groove increases after deformation, thereby ensuring the clamping effect.

[0054] In one embodiment, the clamping unit 39 also includes a rotating motor, the clamping seat 391 includes a fixed seat and a rotating seat, the clamping motor 392, the gear set 393, and the clamping arm set 394 are all arranged on the rotating seat, and the rotating motor is arranged on the fixed seat and can drive the rotating seat to rotate. In this way, when the clamping unit 39 clamps the quantitative circular frame 122 and moves from the main frame plate 11 to the biological placement part 4, the rotating seat is driven to rotate by the rotating motor, and the solution in the quantitative circular frame 122 can be shaken, so that the plankton is evenly distributed in the solution, ensuring the observation effect.

[0055] like Figure 1 and Figure 8As shown, in one embodiment, the biological placement component 4 further includes a temperature control component 43, which includes a heat conductive sheet 44 disposed under the placement tube seat 42, and a fan 45 disposed under the heat conductive sheet 44. In this way, the fan 45 is used to blow cold air or hot air onto the heat conductive sheet 44, and the heat transfer effect of the heat conductive sheet 44 is used to control the temperature of the quantitative circular frame 122 on the placement tube seat 42.

[0056] In one embodiment, the temperature control assembly 43 further includes a heating unit disposed below the ducting fan 45. In this way, the air is heated by the heating unit, and the ducting fan 45 can be used to blow the hot air onto the heat conducting sheet 44.

[0057] In one embodiment, the microscopic observation component 2 also includes a mounting base, a lifting base and a lifting unit. The digital microscope head 21 and the display screen 22 are arranged on the lifting base. The lifting unit includes a lifting motor arranged on the lifting base, a lifting gear arranged at the output end of the lifting motor, and a rack portion arranged on the mounting base. The lifting motor drives the lifting gear to rotate, and the lifting gear and the rack portion are meshed and driven to make the lifting base perform a lifting action relative to the mounting base. In this way, the lifting unit drives the lifting base to perform a lifting action relative to the mounting base, and adjusts the distance from the mirror of the digital microscope head 21 to the quantitative circular frame 122 to ensure the shooting clarity of the digital microscope head 21.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
