In the in-situ culture device for microorganisms in a water environment provided by the utility model, the telescopic mechanism can drive the suspension rope to move to change the offshore distance of the culture container, and when the length of the suspension rope remains unchanged, the telescopic movement of the telescopic mechanism can also simultaneously change the draft of the culture container. The winding mechanism can change the length of the suspension rope to change the draft of the culture container.

[0045] The following is a detailed description of the in-situ culture device for microorganisms in aquatic environments provided by the embodiments of the present invention in conjunction with the accompanying drawings.

[0046] See also Figure 1 to Figure 6 An embodiment of the utility model provides an in-situ culture device for microorganisms in an aquatic environment, comprising a culture container 500 and a suspension device, wherein the suspension device is used to be fixed on the ground near the shore and to suspend the culture container 500 in the water.

[0047] The culture container 500 is used to place microbial samples and to colonize the microorganisms at the same location in the same water environment to ensure that the environment in which the microbial samples are located has the same hydrological conditions.

[0048] The suspension device includes a support 100, a telescopic mechanism 200, a reeling mechanism 300 and a suspension rope 400. The support 100 is used to be fixed on the ground at the shore, the driving part of the telescopic mechanism 200 is connected to the support 100, the telescopic part is suspended on the water surface, and the telescopic direction of the telescopic mechanism 200 has a component along the horizontal direction. The reeling mechanism 300 can be arranged on the telescopic mechanism 200, or can also be arranged on the support 100, one end of the suspension rope 400 is wound on the reeling mechanism 300, and the other end of the suspension rope 400 is connected to the culture container 500, and the middle part of the suspension rope 400 can choose to bypass the telescopic end of the telescopic mechanism 200 or not bypass the telescopic end of the telescopic mechanism 200 according to the setting position of the reeling mechanism 300.

[0049] In a specific embodiment, the driving part of the telescopic mechanism 200 is connected to the support 100, and the telescopic part is telescoped in a direction close to or away from the shore. The winding mechanism 300 is arranged on the support 100 and is located near the end of the driving part away from the telescopic part. One end of the hanging rope 400 is wound on the winding mechanism 300, and the other end of the hanging rope 400 passes around the end of the telescopic part away from the driving part and then extends vertically downward, and the free end of the hanging rope 400 is connected to the culture container 500.

[0050] In another embodiment, when the driving part of the telescopic mechanism 200 is a fixed part, the winding mechanism 300 can also be set on the driving part, one end of the hanging rope 400 is wound on the winding mechanism 300, and the other end of the hanging rope 400 passes around the end of the telescopic part away from the driving part and extends vertically downward, and the free end of the hanging rope 400 is connected to the culture container 500.

[0051] In the above two embodiments, when the telescopic mechanism 200 works alone and the winding mechanism 300 does not work, the length of the suspension rope 400 remains unchanged, and the telescopic end of the telescopic mechanism 200 telescopes toward or away from the shore, thereby simultaneously changing the offshore distance and the draft of the culture container 500. Specifically, the offshore distance of the culture container 500 increases while the draft decreases, and the offshore distance of the culture container 500 decreases while the draft increases.

[0052] When the telescopic mechanism 200 and the reeling mechanism 300 work simultaneously, the telescopic end of the telescopic mechanism 200 is telescoped toward or away from the shore, which can change the offshore distance of the culture container 500, and the reeling mechanism 300 rotates to change the length of the suspension rope 400 to change the draft of the culture container 500. The reeling mechanism 300 cooperates with the telescopic mechanism 200 to change the offshore distance of the culture container 500 while keeping the draft of the culture container 500 unchanged, or to increase or decrease the draft of the culture container 500.

[0053] When the telescopic mechanism 200 is not working and only the reeling mechanism 300 is working, the offshore distance of the culture container 500 remains unchanged and only the draft of the culture container 500 is changed.

[0054] In another specific embodiment, the reeling mechanism 300 may also be disposed on the telescopic portion of the telescopic mechanism 200 , and more specifically, may be disposed at an end of the telescopic portion away from the driving portion.

[0055] In this embodiment, the telescopic mechanism 200 working alone can change the offshore distance of the culture container 500, and the winding mechanism 300 working alone can change the draft of the culture container 500. The telescopic mechanism 200 and the winding mechanism 300 working simultaneously can change the offshore distance and the draft of the culture container 500 at the same time.

[0056] In some embodiments of the utility model, the telescopic mechanism 200 includes a sleeve 210 and a screw 220. The sleeve 210 can be selectively connected to the support 100 for rotation, and the movement of the sleeve 210 along its own axis is restricted. The screw 220 is threaded into the sleeve 210, and the screw 220 is connected to the support 100 for sliding movement. The support 100 also restricts the rotation of the screw 220. At this time, the driving part is the sleeve 210, and the telescopic part is the screw 220.

[0057] Since the sleeve 210 is a rotating part, the winding mechanism 300 can be selectively set on the support 100 or on the screw 220. In this embodiment, the winding mechanism 300 is set on the support 100. At the end of the sleeve 210 away from the screw 220, the sleeve 210 can be selectively connected to the winding mechanism 300 in transmission. When the winding mechanism 300 is connected to the sleeve 210 in transmission, the winding mechanism 300 rotates, which can simultaneously drive the sleeve 210 to rotate, thereby driving the screw 220 to extend outward or retract inward.

[0058] It should be noted that the screw 220 and the sleeve 210 may also be interchanged so that the screw 220 is rotationally connected to the support 100 and the sleeve 210 is slidingly connected to the support 100. In this case, the driving part is the screw 220 and the telescopic part is the sleeve 210.

[0059] Alternatively, the telescopic mechanism 200 may be a pneumatic push rod or an electric push rod, etc. In other words, any telescopic mechanism 200 that can drive the free end of the suspension rope toward or away from the shore is within the protection scope of the present application.

[0060] In some embodiments of the utility model, the winding mechanism 300 includes a winding wheel 310 and a driving device. When the winding mechanism 300 is arranged on the support 100, the winding wheel 310 is rotatably connected to the support 100, and the rotation axis of the winding wheel 310 is perpendicular to the telescopic direction of the telescopic mechanism 200. The driving device includes a first driving end and a second driving end. The first driving end is used to be connected to the winding wheel 310 in a transmission manner to drive the winding wheel 310 to rotate, and the second driving end is used to be connected to the driving part of the telescopic mechanism 200 in a transmission manner to provide power to the driving part of the telescopic mechanism 200.

[0061] In some embodiments of the utility model, the driving device may include a driving shaft 321 and a rotating handle 322. A rotating shaft 330 is arranged between the winding wheel 310 and the support 100. The rotating shaft 330 is rotatably connected to the support 100. The rotating axis is perpendicular to the telescopic direction of the telescopic mechanism 200. The rotating shaft 330 is fixedly connected to the winding wheel 310 and rotates synchronously with the winding wheel 310.

[0062] The first driving end of the driving device is rotatably connected to the first end of the rotating shaft 330, that is, an axial hole connected to the driving end of the driving shaft 321 is provided at the first end of the rotating shaft 330, and the driving end of the driving shaft 321 is inserted into the axial hole of the rotating shaft 330, and the two are rotatably connected. At the same time, a stop structure is also provided between the driving end of the driving shaft 321 and the axial hole of the first end of the rotating shaft 330, and the stop structure is a detachable structure. When the stop structure is provided between the driving shaft 321 and the rotating shaft 330, the driving shaft 321 can drive the rotating shaft 330 to rotate synchronously, thereby driving the winding wheel 310 to rotate synchronously. When the stop structure is removed from between the driving shaft 321 and the rotating shaft 330, the driving shaft 321 and the rotating shaft 330 rotate relative to each other, and the driving shaft 321 cannot drive the rotating shaft 330 to rotate.

[0063] Specifically, the anti-rotation structure includes a first mounting groove 341, a second mounting groove 342 and a anti-rotation strip 343. The first mounting groove 341 can be set on the outer peripheral surface of the driving end of the driving shaft 321, and the first mounting groove 341 extends in parallel to its own axial direction. The second mounting groove 342 is set on the inner wall of the shaft hole at the first end of the rotating shaft 330, and the second mounting groove 342 extends in parallel to its own axial direction. The anti-rotation strip 343 can be set in the first mounting groove 341 and the second mounting groove 342 to limit the relative rotation of the driving shaft 321 and the rotating shaft 330. The anti-rotation strip 343 can also be removed from the first mounting groove 341 and the second mounting groove 342 to release the restriction on the relative rotation of the driving shaft 321 and the rotating shaft 330.

[0064] In some embodiments of the utility model, the driving device also includes a driving shaft 321 and a rotating handle 322. A first bevel gear 351 is provided at a position of the driving shaft 321 near the rotating handle 322, and the first bevel gear 351 rotates coaxially with the driving shaft 321. A second bevel gear 352 is also rotatably provided on the support 100, and the second bevel gear 352 rotates coaxially with the sleeve 210, and the gear teeth of the second bevel gear 352 can mesh with the gear teeth of the first bevel gear 351 for transmission.

[0065] When the first bevel gear 351 is meshed with the second bevel gear 352 and the handle 322 is rotated to drive the driving shaft 321 to rotate, the first bevel gear 351 drives the second bevel gear 352 to rotate, thereby driving the sleeve 210 to rotate.

[0066] In some embodiments of the utility model, the rotating shaft 330 is slidably connected to the support 100, and the sliding direction is along the axis of the rotating shaft 330. The rotating shaft 330 can slide toward the rotating handle 322 to the position where the first bevel gear 351 and the second bevel gear 352 are separated, and can also slide toward the direction away from the rotating handle 322 to the position where the first bevel gear 351 and the second bevel gear 352 are combined.

[0067] Alternatively, the driving shaft 321 and the rotating shaft 330 can be slidably connected, and the sliding direction is along the axial direction of the rotating shaft 330. The driving shaft 321 can move in the direction away from the rotating shaft 330 to the position where the first bevel gear 351 and the second bevel gear 352 are separated, and the driving shaft 321 and the rotating shaft 330 still remain connected. The driving shaft 321 can also move in the direction close to the rotating shaft 330 to the position where the first bevel gear 351 and the second bevel gear 352 are combined.

[0068] In some embodiments of the utility model, the culture container 500 includes a connector 510, at least one suspension rod 520 and at least one container, the container is suspended below the connector 510 by the suspension rod 520, and the top of the connector 510 is connected to the free end of the suspension rope 400. The number of containers is less than or equal to the number of suspension rods 520. The container is provided with a first water-permeable hole, which may be a mesh structure, for example, to ensure that water can enter the container while fixing the microbial sample.

[0069] In some embodiments of the utility model, the culture container 500 further includes a barrel 540, the top of which is open, and a second water-permeable hole is provided on the barrel 540.

After the connection, the container is located in the barrel 540, and the barrel 540 can protect the container. The second water-permeable hole is provided on the barrel 540 to ensure that water can enter the barrel 540.

[0070] In some embodiments of the present invention, the container may include a net bucket 530, and the top of the net bucket 530 is open to facilitate the placement of microbial samples. At the same time, in order to prevent the microbial samples with a density less than that of water from floating upward to the outside of the net bucket 530, a top cover 550 may be provided on the top of the net bucket 530, and the top cover 550 and the net bucket 530 may be threadedly connected to facilitate opening the top cover 550 to place and take the microbial samples.

[0072] When taking or placing samples, the suspension rod 520 can be rotated so that the suspension rod 520 moves upward under the drive of the thread until the threaded section of the suspension rod 520 is disengaged from the threaded hole 512. At this time, the suspension rod 520 can be pulled upward to lift the corresponding net bucket 530 upward to facilitate taking or placing microbial samples.

[0073] In a specific embodiment of the present invention, the support 100 includes a connecting plate 110 , a first support rod 120 , a second support rod 130 , a third support rod 140 and a fourth support rod 150 .

[0078] The first bevel gear 351 is arranged at a position of the driving shaft 321 close to the rotating handle 322, and the gear teeth of the first bevel gear 351 are arranged backward. The first bevel gear 351 can move forward with the driving shaft 321 to a position separated from the second bevel gear 352, and can also move backward with the driving shaft 321 to a position engaged with the second bevel gear 352.

[0079] The fourth support rod 150 is arranged on the left side of the third support rod 140, and a connecting ring 151 is arranged on the top of the fourth support rod 150. The sleeve 210 is inserted into the connecting ring 151, and a limiting groove is arranged at the position where the sleeve 210 is connected to the connecting ring 151, and a thrust bearing is arranged between the limiting groove and the connecting ring 151 to realize the relative rotation of the sleeve 210 and the connecting ring 151, and at the same time limit the axial relative movement of the sleeve 210 and the connecting ring 151.

[0080] An L-shaped limiting rod 160 is provided at the bottom of the end of the screw rod 220 away from the sleeve 210. The L-shaped limiting rod 160 includes a vertical portion and a horizontal portion. The top end of the vertical portion is connected to the screw rod 220, and the left end of the horizontal portion is connected to the bottom end of the vertical portion. A limiting hole is also provided on the fourth support rod 150, which penetrates the fourth support rod 150 in the left-right direction. The right end of the horizontal portion passes through the limiting hole to the right, and a limiting plate 161 having a size larger than the size of the limiting hole is provided at the right end of the horizontal portion.

[0081] In this way, the L-shaped limit rod 160 can limit the rotation of the screw 220, so that the screw 220 can only move axially relative to the sleeve 210. At the same time, the limit plate 161 can also limit the maximum extension length of the screw 220. When the limit plate 161 contacts the fourth support rod 150, it ensures that the screw 220 is still located in the sleeve 210, preventing the screw 220 from excessive movement and separation from the sleeve 210.

[0082] To improve the structural strength, reinforcing rods 170 may be further provided between the first support rod 120 and the second support rod 130 , between the second support rod 130 and the third support rod 140 , and between the third support rod 140 and the fourth support rod 150 .

[0083] In order to improve stability, the first support rod 120, the second support rod 130, the third support rod 140 and the fourth support rod 150 all penetrate the connecting plate 110 downward and are buried underground, and a counterweight 180 is also provided at the bottom of the first support rod 120, the second support rod 130, the third support rod 140 and the fourth support rod 150. At the same time, the connecting plate 110 can be connected to the ground by long screws.

[0084] In addition, a fixed pulley 360 is provided at one end of the screw 220 away from the sleeve 210, and the axis of the fixed pulley 360 is parallel to the axis of the winding wheel 310. One end of the suspension rope 400 is wound on the winding wheel 310, and the other end of the suspension rope 400 passes around the fixed pulley 360 and extends downward, and is connected to the culture container 500.

[0085] There are three ways to adjust the offshore distance and draft of the culture container 500:

[0086] The first method is to connect the anti-rotation bar 343 to the first installation groove 341, and then insert the driving end of the driving shaft 321 into the shaft hole of the rotating shaft 330. At the same time, the anti-rotation bar 343 also enters the second installation groove 342, pushing the driving shaft 321 to move backward, so that the first bevel gear 351 on the driving shaft 321 is meshed with the second bevel gear 352. At this time, the rotating handle is rotated, and the winding wheel 310 can be driven to rotate through the driving shaft 321 and the rotating shaft 330. At the same time, the first bevel gear 351 and the second bevel gear 352 can drive the sleeve 210 to rotate. When the handle 322 is turned to drive the winding wheel 310 to release the rope, the sleeve 210 drives the screw 220 to extend outward, so that the suspension rope 400 is extended, and the screw 220 extends outward.

[0087] The second method is to remove the drive shaft 321 from the shaft hole of the rotating shaft 330, remove the anti-rotation strip 343, and then reinsert the drive shaft 321 into the shaft hole of the rotating shaft 330, and mesh the first bevel gear 351 with the second bevel gear 352. At this time, the handle 322 is turned to drive the drive shaft 321 to rotate, and the drive shaft 321 cannot drive the rotating shaft 330 to rotate, and the winding wheel 310 is fixed. The first bevel gear 351 and the second bevel gear 352 are meshed and driven to drive the sleeve 210 to rotate, and the sleeve 210 drives the screw 220 to extend and retract, so that the offshore distance of the culture container 500 changes. Since the winding wheel 310 is fixed, the length of the suspension rope 400 remains unchanged, and the extension and retraction of the screw 220 will change the length of the suspension rope 400 in the vertical part. The culture container 500 will change the draft while changing the offshore distance.

[0088] The third method is to pull the driving shaft 321 out of the shaft hole of the rotating shaft 330 for a certain distance, but ensure that the anti-rotation bar 343 is still located in the first installation groove 341 and the second installation groove 342, and the first bevel gear 351 and the second bevel gear 352 are separated. When the handle 322 is turned to drive the driving shaft 321 to rotate, the driving shaft 321 can drive the rotating shaft 330 to rotate, and then the winding wheel 310 can rotate to change the length of the hanging rope 400, so as to achieve the effect of changing the draft of the culture container 500 alone.

[0089] When sampling, the microbial sample is placed inside the net bucket 530, the top cover 550 is connected to the top of the net bucket 530 by threaded engagement, the bottom of the suspension rod 520 is connected to the net bucket 530, the top of the suspension rod 520 passes upward through the through hole 511 of the connector 510, and the suspension rod 520 is fixedly connected to the threaded hole 512 of the connector 510 by threaded engagement, and then the cylinder 540 is threadedly connected to the connector 510, and the above-mentioned adjustment method is selected to hang the culture container 500 into the water through the suspension rope 400.

[0090] During the culture process, the above-mentioned adjustment method can be selected to change the draft depth and the distance from the shore of the culture container 500.

[0091] When sampling, the third adjustment method can be selected to reduce the draft of the culture container 500 alone and pull the culture container 500 out of the water for sampling. Alternatively, the first adjustment method can be selected to reduce the draft of the culture container 500 while reducing the distance from the shore, pull the culture container 500 out of the water and pull it to the shore for sampling.
