[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-11 As shown, the embodiment provided by the present invention is: a detector for detecting microorganism species in water, comprising a support base 110, an incubator shell 120, an observation microscope 130, a placement tray 140, a placement groove 150 and a culture dish 160, wherein the top of the support base 110 is fixedly connected to the incubator shell 120, and the observation microscope 130 is inserted into the right side of the top of the incubator shell 120, a placement tray 140 is placed inside the incubator shell 120, and four groups of placement grooves 150 are opened inside the placement tray 140, and culture dishes 160 are placed inside the four groups of placement grooves 150, an automatic dripping mechanism is provided inside the incubator shell 120, and a positioning locking mechanism is provided below the placement tray 140;

[0032] The automatic dripping mechanism includes a first chamber 210, a first chamber 210 is provided inside the outer shell 120 of the incubator, and a first rotating rod 220 is connected to the inner wall bearing at the bottom end of the first chamber 210, a positioning base 230 is fixedly connected to the top of the first rotating rod 220, and a first disc 240 is fixedly connected to the outer wall of the first rotating rod 220, four groups of limiting grooves 250 are provided inside the first disc 240, a second rotating rod 260 is connected to the bearing inside the first chamber 210, and a first handle 270 is fixedly connected to the bottom end of the second rotating rod 260, a second disc 280 is fixedly connected to the top end of the second disc 280, and a limiting rod 290 is fixedly connected to the left end of the support base 110. Two groups of fixing plates 310 are fixedly connected, and the fixing The internal bearing of the fixed plate 310 is connected to the third rotating rod 320, and the bottom end of the third rotating rod 320 and the outer wall of the second rotating rod 260 are fixedly connected to the pulley 330, and a transmission belt 340 is wound between the two sets of pulleys 330. The top of the third rotating rod 320 is fixedly connected to the cam 350, and the top of the support base 110 is fixedly connected to the support frame 360, and the top of the support frame 360 ​​is installed with a sample bottle 370, and the bottom end of the sample bottle 370 is fixedly connected to a drip pipe 380, and a sealing groove 390 is provided inside the drip pipe 380, and a sealing plate 391 is passed through the sealing groove 390, and the sealing plate 391 is inserted into the support frame 360, and a water outlet hole 392 is provided inside the sealing plate 391. The left end of the sealing plate 391 is fixedly connected There is an abutment plate 394, and the left end of the abutment plate 394 is connected to a fixed pulley 395 through a rotating shaft. The left end of the fixed pulley 395 abuts against the cam 350, and the outer wall of the sealing plate 391 is wound with a spring 396. In specific operation, rotating the first handle 270 can drive the second rotating rod 260, the second disc 280 and the limiting rod 290 to rotate. At the same time, through the transmission of the pulley 330 and the transmission belt 340, the third rotating rod 320 and the cam 350 can be driven to rotate. When the cam 350 rotates 180 degrees, the fixed pulley 395, the abutment plate 394, the sealing plate 391 and the water outlet 392 can be driven to move to the right. At this time, the drip pipe 380 is closed, and the first handle 270 is continued to be rotated. At this time, the limiting rod 290 enters the limiting groove 25 0 and drives the first disc 240, the first rotating rod 220, the positioning base 230 and the placement tray 140 to rotate 90 degrees, thereby replacing the culture dish 160 below the dripping pipe 380. The first handle 270 is rotated continuously to complete one circle. At this time, the dripping pipe 380 is opened again, and liquid can be dripped to another group of culture dishes 160 below the dripping pipe 380. The above operation can be repeated by continuously rotating the first handle 270, so that the operator only needs to continuously rotate the first handle 270 to complete the quantitative dripping of multiple groups of culture dishes 160. In addition, when the placement tray 140 rotates, the dripping pipe 380 is closed at the same time, which prevents the liquid inside the dripping pipe 380 from dripping to the outside of the culture dishes 160, thereby ensuring the utilization rate of the samples.

[0033] The top of the second disk 280 is fixedly connected to the limiting block 281, and the shape of the limiting block 281 is set to be fan-shaped. When the limiting rod 290 enters the limiting groove 250, it can drive the first disk 240 to rotate clockwise. When the first disk 240 rotates 90 degrees, the outer wall of the limiting block 281 fits the first disk 240 again, so that the first disk 240 can stop after rotating 90 degrees, avoiding the first disk 240 from rotating too much due to inertia, thereby ensuring the rotation accuracy of the first disk 240 and the placement tray 140.

[0034] The outer wall of the dripping pipe 380 is fixedly connected to a fixing frame 381, and the top of the fixing frame 381 is fixedly connected to the inner wall of the top of the incubator outer shell 120. The fixing of the dripping pipe 380 by the fixing frame 381 can ensure the stability of the bottom end of the dripping pipe 380 during dripping, thereby ensuring the dripping effect.

[0035] Four groups of positioning grooves 231 are provided inside the positioning base 230, and positioning blocks 232 are inserted into the four groups of positioning grooves 231. The ends of the positioning blocks 232 away from the positioning grooves 231 are fixedly connected to the placement tray 140. When the operator places the placement tray 140, the four groups of positioning blocks 232 are inserted into the positioning grooves 231. At this time, the culture dish 160 is located directly below the drip pipe 380, thereby positioning the culture dish 160 and further increasing the stability of the placement tray 140 during rotation.

[0036] A sealing gasket 393 is fixedly connected to the inner wall of the sealing groove 390, and the sealing gasket 393 is made of rubber. When the sealing plate 391 moves left and right, the sealing gasket 393 can ensure the sealing of the dripping pipe 380 to prevent sample leakage.

[0037] The positioning locking mechanism includes a second chamber 410, a second chamber 410 is opened inside the placement tray 140, and a sleeve 420 is connected to the bearing on the inner wall of the bottom end of the second chamber 410, and the top of the sleeve 420 is fixedly connected to the third disc 430, and the top of the third disc 430 is connected to four sets of hinged rods 440 through a rotating shaft, and the ends of the four sets of hinged rods 440 away from the third disc 430 are all fixedly connected to the connecting rods 450, and the connecting rods 450 are all inserted into the placement groove 150. The ends of the connecting rods 450 away from the hinged rods 440 are fixedly connected to the clamping blocks 460, and the clamping blocks 460 are all in contact with the culture dish 160. The internal thread of the placement tray 140 is connected to the threaded rod 470, and the outer wall of the threaded rod 470 is fixedly connected to the sleeve 480. The sleeve 480 is slidably connected to the third disc 430. The top of the threaded rod 470 is fixedly connected to the second handle 490. A nut groove 491 is opened inside the positioning base 230, and the nut groove 491 is threadedly connected to the threaded rod 470. In specific operation, the placement tray 140 is placed above the positioning base 230, and the second handle 490 is rotated to drive the threaded rod 470 and the sleeve 480 to move downward, while driving the third disc 430 to rotate. Through the transmission of the hinged rod 440, the connecting rod 450 and the clamping block 460 can be driven to move toward the end away from the third disc 430, thereby driving the clamping block 460 to clamp and fix the culture dish 160 and complete the positioning. At the same time, since the threaded rod 470 is threadedly connected to the placement tray 140, the threaded rod 470 and the sleeve 480 can be moved downward, and the threaded rod 470 is threadedly connected to the inside of the nut groove 491. At this time, the placement tray 140 and the positioning base 230 are locked, ensuring the stability of the placement tray 140 during rotation, so that the operator can position and fix the culture dish 160 while also locking the placement tray 140 and the positioning base 230 when turning the second handle 490.

[0038] The shape of the clamping block 460 away from the end of the connecting rod 450 is set to be arc-shaped, and an anti-slip pad 461 is fixedly connected to the inner side of the clamping block 460. The anti-slip pad 461 is made of rubber. When the clamping block 460 clamps the culture dish 160, the anti-slip pad 461 can further increase the friction between the device and the culture dish 160, thereby ensuring the clamping effect, and can also protect the culture dish 160 to prevent the outer surface of the culture dish 160 from being damaged.

[0039] A sliding groove 481 is provided on the outside of the sleeve 480, and a slider 482 is slidably connected inside the sliding groove 481. The end of the slider 482 away from the sliding groove 481 is fixedly connected to the inner wall of the third disc 430. When the threaded rod 470 moves downward, the slider 482 slides inside the sliding groove 481, thereby ensuring that the sleeve 480 can move downward while driving the third disc 430 to rotate.

[0040] Working principle:

[0041] The first handle 270 is rotated to rotate the second rotating rod 260, the second disc 280 and the limiting rod 290. At the same time, the third rotating rod 320 and the cam 350 are driven to rotate by the pulley 330 and the transmission belt 340. When the cam 350 rotates 180 degrees, the fixed pulley 395, the abutting plate 394, the sealing plate 391 and the water outlet 392 are driven to move to the right. At this time, the dripping pipe 380 is closed. The first handle 270 is further rotated. At this time, the limiting rod 290 enters the limiting groove 250 and drives the first disc 240, the first rotating rod 220, the positioning base 230 and the placement tray 140 to rotate 90 degrees, thereby replacing the culture dish 160 below the dripping pipe 380. The first handle 270 is further rotated to complete one circle. At this time, the dripping pipe 380 is opened again, and another group of culture dishes 160 below the dripping pipe 380 can be dripped.

[0042] The process of locking the culture dish 160 in position and locking the placement tray 140 and the positioning base 230 at the same time: place the placement tray 140 above the positioning base 230, rotate the second handle 490, drive the threaded rod 470 and the sleeve 480 to move downward, and at the same time drive the third disc 430 to rotate, and through the transmission of the hinged rod 440, the connecting rod 450 and the clamping block 460 can be driven to move toward the end away from the third disc 430, thereby driving the clamping block 460 to clamp and fix the culture dish 160, and complete the positioning. At the same time, since the threaded rod 470 is threadedly connected to the placement tray 140, the threaded rod 470 and the sleeve 480 can be moved downward, and the threaded rod 470 is threadedly connected to the inside of the nut groove 491. At this time, the placement tray 140 and the positioning base 230 are completely locked, and the operation is completed.
