Detailed implementation manners

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0037] Please refer to Figures 1 to 9 together, and now a moving device for a floating bacteria collection robot provided by the present utility model will be described. The moving device for a floating bacteria collection robot is arranged at the bottom of the sampling workbench 1, and includes a base 2, at least two support frames 3 and a connecting mechanism 4; the base 2 has traveling wheels 21, and the traveling wheels 21 are rotationally matched with the base 2; a driving structure (not shown in the figure) for driving the traveling wheels 21 to rotate is arranged inside the base 2; in this embodiment, two support frames 3 are taken as an example for description, and each support frame 3 is a U-shaped structure, and the opening of the U-shaped structure faces the sampling workbench 1; the two support frames 3 are both arranged on the top of the base 2; the support frame 3 has a cross beam 31, and the cross beam 31 contacts the bottom of the sampling workbench 1; the connecting mechanism 4 is arranged between the cross beam 31 and the bottom of the sampling workbench 1; after the sampling workbench 1 is placed on the cross beam 31, the connecting mechanism 4 connects the support frame 3 and the sampling workbench 1 to limit the position of the sampling workbench 1.

[0038] A mobile device for a floating bacteria sampling robot provided by the present utility model, compared with the prior art, the sampling workbench 1 is fixed on the base 2 through the cooperation of the support frame 3 and the connection mechanism 4. By driving the driving structure to drive the walking wheels 21 to rotate, the base 2 can drive the sampling workbench 1 to move to the next sampling position. The manipulator on the sampling workbench 1 can automatically grab the culture dish on the sampling workbench 1 and place the culture dish at the sampling port. By starting the air extraction component, the sampling operation of the next sampling position can be completed; through the above settings of the present application, there is no need for an operator to push the sampling workbench 1 to the next sampling position, which can reduce the labor intensity of the operator.

[0039] In some embodiments, as Figures 1 to 9 shown, the bottom of the sampling workbench 1 has threaded holes, and the support frame 3 has through holes aligned with the threaded holes on the sampling workbench 1; the connection mechanism 4 includes bolts 41, and the threaded ends of the bolts 41 pass through the cross beam 31 and are threadedly engaged with the sampling workbench 1.

[0040] It should be noted that after the sampling workbench 1 is placed on the support frame 3, the threaded holes on the sampling workbench 1 are aligned with the through holes on the support frame 3. At this time, the threaded ends of the bolts 41 pass through the through holes of the support frame 3 and are threadedly engaged with the sampling workbench 1, which can fix the sampling workbench 1 on the support frame 3.

[0041] Exemplarily, the support frame 3 is fixed on the base 2, and the support frame 3 is cooperated with the base 2 through bolts 41, or the support frame 3 is welded to the base 2.

[0042] In some embodiments, as Figures 1 to 9 shown, the sampling workbench 1 has a control module, which is electrically connected to the driving structure on the base 2; the top of the base 2 has a support portion 22, and the support portion 22 is used to contact the bottom of the sampling workbench 1; the top of the support portion 22 has a first cable interface, and the bottom of the driving workbench has a second cable interface, and the first cable interface and the second cable structure are plugged and matched.

[0043] It should be noted that the control module in the sampling workbench 1 is electrically connected to the driving structure on the base 2. When it is necessary to move to the next sampling location, the control module can transmit a control signal to the driving structure, so that the driving structure drives the walking wheels 21 to move, thereby making the sampling workbench 1 move to the next sampling location.

[0044] Exemplarily, the driving structure includes a servo motor, and the servo motor is fixed inside the base 2, and the servo motor can drive the walking wheels 21 on the practice to rotate.

[0045] In some embodiments, as Figures 1 to 9As shown, the connecting mechanism 4 includes a positioning post 42. The positioning post 42 is arranged on the cross beam 31 of the support frame 3. The bottom of the sampling workbench 1 has a jack 11 that is inserted and matched with the positioning post 42. A protruding portion 43 is also provided on the cross beam 31, and a groove 12 for being inserted and matched with the protruding portion 43 is provided on the sampling workbench 1. Among them, when the positioning post 42 is aligned with the jack 11 and the protruding portion 43 is aligned with the groove 12, the first cable interface and the second cable interface are aligned. Before the first cable interface and the second cable interface are inserted, the positioning post 42 is first inserted and matched with the jack 11.

[0046] It should be noted that by providing the positioning post 42 and the protruding portion 43 on the support frame 3, after the sampling workbench 1 is placed on the support frame 3, when the positioning post 42 and the protruding portion 43 are not aligned with the jack 11 and the groove 12, the positioning post 42 and the protruding portion 43 can support the sampling workbench 1, which is convenient for adjusting the installation position of the sampling workbench 1. During the process of adjusting the installation position of the sampling workbench 1, there is a gap between the first cable interface and the second cable interface. Therefore, when the sampling workbench 1 adjusts its position, it will not cause damage to the first cable interface and the second cable interface. After the sampling workbench 1 adjusts its position, the positioning post 42 is inserted and matched with the jack 11, the protruding portion 43 is inserted and matched with the groove 12, the first cable interface and the second cable interface are inserted and matched, and then they are fixed by bolts 41. In the above way, after the sampling workbench 1 is installed in place, the first cable interface and the second cable interface can be inserted.

[0047] In some embodiments, as Figures 1 to 9 shown, when each support frame 3 is arranged in parallel, the connecting mechanism 4 includes several groups of guide plates 44, insertion rods 45 and elastic parts 46. Several groups of guide plates 44 correspond to the support frames 3 one by one. Each group of guide plates 44 has two, and the two guide plates 44 are respectively in contact with both sides of one of the support frames 3. The guide plates 44 are connected to the bottom of the sampling workbench 1. The insertion rod 45 is slidably arranged on the guide plate 44. The sliding direction of the insertion rod 45 is perpendicular to the sliding direction of the sampling workbench 1. Among them, the guide plate 44 has a through hole for the insertion rod 45 to pass through. One end of the elastic part 46 is connected to the insertion rod 45, and the other end is connected to the guide plate 44. Among them, the support frame 3 has a positioning hole 32 for being inserted and matched with the insertion rod 45. When the sampling workbench 1 slides in place, the insertion rod 45 is inserted and matched with the positioning hole 32. The elastic part 46 includes a spring, the spring is sleeved on the insertion rod 45, and both ends of the spring are respectively connected to the insertion rod 45 and the guide plate 44.

[0048] In this embodiment, the sampling workbench 1 is installed on the support frame 3 by sliding, so there is no support portion 22 provided on the base 2, otherwise it will interfere with the sliding of the sampling workbench 1; in this embodiment, the first cable interface is provided at the top of the base 2, and the second cable interface on the sampling workbench 1 has an extension cable, which can enable the second cable interface to be plugged and matched with the first cable interface.

[0049] By respectively arranging guide plates 44 on both sides of the support frame 3, it can play a role in limiting the sliding direction of the sampling workbench 1; after the sampling workbench 1 slides in place, the insertion rod 45 can be aligned with the positioning hole 32, and under the elastic force of the elastic portion 46, the insertion rod 45 can be kept in a state of being plugged into the positioning hole 32; through the above settings, the sampling workbench 1 can be fixed on the base 2.

[0050] It should be noted that when the end of the sampling workbench 1 slides to the position of the insertion rod 45, the operator needs to manually pull the insertion rod 45 outwards so that the sampling workbench 1 can continue to slide. At this time, release the insertion rod 45, and the inner end of the insertion rod 45 can abut against the outer wall of the sampling workbench 1; after the sampling workbench 1 slides in place, the insertion rod 45 can be inserted into the positioning hole 32.

[0051] In some embodiments, as Figures 1 to 9 shown, each group of guide plates 44 has a baffle 47 at its end, and the baffle 47 is used to contact the end of the support frame 3 to limit the final position of the sampling workbench 1 and the support frame 3.

[0052] It should be noted that by arranging the baffle 47 at the end of the guide plate 44, after the sampling workbench 1 slides in place, the baffle 47 contacts the end of the support frame 3, and at this time, the sampling workbench 1 cannot continue to slide; through the above settings, the sliding position of the sampling workbench 1 can be limited, and the situation where the sampling workbench 1 slides out of the support frame 3 can be reduced.

[0053] In some embodiments, as Figures 1 to 9 shown, the other side of the support frame 3 has a threaded hole communicating with the positioning hole 32, and a setscrew 48 is provided in the threaded hole, and the setscrew 48 is entirely located in the threaded hole; there is an avoidance hole 441 on the guide plate 44 on the other side of the support frame 3 for aligning with the setscrew 48; wherein, the setscrew 48 is used to eject the insertion rod 45 inside the support frame 3.

[0054] It should be noted that when installing the sampling workbench 1 on the support frame 3, when the setscrew 48 is in the initial position, at this time, the insertion rod 45 can be plugged and matched with the positioning hole 32; when it is necessary to remove the sampling workbench 1 from the base 2, by rotating the setscrew 48, the setscrew 48 can eject the insertion rod 45 from the positioning hole 32, thereby facilitating the removal of the sampling workbench 1 from the base 2.

[0055] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
