Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to a sample tube cleaning device for environmental monitoring. Background Art

[0002] In the field of environmental monitoring technology, in order to better detect the environment (such as soil, water source, etc.), a sample tube, a tubular container, is usually used to collect the substances to be detected and store these collected environmental samples so that subsequent staff can subsequently detect the environmental samples;

[0003] After using sample tubes for environmental monitoring for a period of time, staff usually need to clean these sample tubes centrally. However, the existing cleaning method only cleans the sample tubes by inverting the sample tubes and flushing the inside of the sample tubes with a water pipe. In addition, since the sample tubes and the water pipes are in a relatively static state, the contact area between the sample tubes and the water source will be single, resulting in uneven cleaning of the inside of the sample tubes. As a result, some impurities will still remain in the sample tubes after cleaning, which will cause cross-contamination with environmental samples during subsequent use, which is not conducive to sample sampling and detection.

[0004] Therefore, we proposed a sample tube cleaning device for environmental monitoring to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a sample tube cleaning device for environmental monitoring, which solves the problems raised in the above-mentioned background technology.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0008] As a further solution of the utility model: the lifting plate is rotatably connected to a connecting rod on the upper side away from the fixed frame, the connecting rod is rotatably connected to a slider on the end away from the lifting plate, the cleaning box is provided with a sliding groove on the side close to the slider, and the slider is slidably connected in the sliding groove.

[0009] As a further solution of the utility model: the front ends of the sliding blocks are fixedly connected with sliding columns, the front ends of the sliding columns are penetrated and slidably connected to the cleaning box, and moving plates are fixedly connected between the front ends of the sliding columns.

[0010] As a further solution of the utility model: a driving shaft passes through the movable plate, one end of the driving shaft is rotatably connected to the side wall of the cleaning box, the other end of the driving shaft is fixedly connected to the driving motor, a reciprocating groove is opened on the outer surface of the driving shaft, a sliding ball is slidably connected in the reciprocating groove, and the sliding ball is fixedly connected to the center of the movable plate.

[0011] As a further solution of the utility model: the upper end surface of the lifting plate is provided with a card slot, the card slot is clamped with a card block, a cross plate is fixedly connected between the card blocks, connecting columns are symmetrically inserted and slid through the cross plate, and a sponge board is fixedly connected between the lower ends of the connecting columns.

[0012] As a further solution of the utility model: a threaded rod is rotatably connected to the center of the upper end surface of the sponge board, the threaded rod penetrates and is rotatably connected to the horizontal plate, and a knob is fixedly connected to the upper end of the threaded rod.

[0013] Beneficial effects of the utility model:

[0014] 1. By centrally clamping the sample tubes on the fixing rack and making the fixing rack swing back and forth during the cleaning process of the sample tubes, the water source sprayed from the water pipe can be in more complete contact with the inner surface of the sample tube, so that the cleaning liquid covers a wider area on the inner wall of the sample tube, thereby increasing the contact area between the water and the tube wall, improving the cleaning effect of the sample tube, and by reciprocatingly shaking the sample tube, it can also help the water or cleaning liquid to be evenly distributed inside the sample tube, so that the liquid can form a liquid circulation inside the sample tube, flushing the pollutants from the tube wall, thereby achieving more uniform cleaning.

[0015] 2. By setting the sponge plate above the fixing frame, the sponge plate can be mutually connected with the sample tube during the cleaning process, so that the sample tube can be tightly connected to the fixing frame, avoiding the shaking of the sample tube on the fixing frame when the fixing frame is subsequently swung, causing the sample tube and the fixing frame to collide and break, thereby strengthening the protection of the sample tube and reducing the risk of damage to the sample tube during cleaning.

[0016] 3. By installing the horizontal plate on the lifting plate in a snap-fit ​​manner, the horizontal plate can be removed from the cleaning box when the sample tube is placed on the fixed rack, thereby facilitating the placement of the sample tube and avoiding the presence of the sponge plate blocking the placement of the sample tube.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example

[0027] like Figure 1-5 As shown, a sample tube cleaning device for environmental monitoring includes a cleaning box 1, a water pipe 6 is fixedly connected to the bottom of the cleaning box 1, and nozzles 16 are fixedly connected equidistantly above the outer surface of the water pipe 6. Lifting plates 7 are symmetrically and vertically slidably connected inside the cleaning box 1, and fixed frames 8 are fixedly connected between the lifting plates 7.

[0028] In this embodiment, Figure 3 and Figure 4As shown, the lifting plate 7 is rotatably connected to the upper side of the fixing frame 8 with a connecting rod 5, and the connecting rod 5 is rotatably connected to the end of the lifting plate 7 away from the lifting plate 7. A sliding groove 17 is provided on the side of the cleaning box 1 close to the sliding groove 18, and the sliding groove 18 is slidably connected to the sliding groove 17. When the sliding groove 18 slides in the sliding groove 17, the lifting plate 7 can be driven to reciprocate up and down through the arranged connecting rod 5.

[0029] In this embodiment, Figure 1 As shown, the front ends of the sliders 18 are fixedly connected with the slide posts 4, the front ends of the slide posts 4 are slidably connected to the cleaning box 1, and the moving plates 3 are fixedly connected between the front ends of the slide posts 4. During the movement of the moving plates 3, the slide posts 4 are set to push the sliders 18 to slide back and forth in the slide grooves 17.

[0030] In this embodiment, Figure 5 As shown, a driving shaft 2 passes through the movable plate 3, one end of the driving shaft 2 is rotatably connected to the side wall of the cleaning box 1, and the other end of the driving shaft 2 is fixedly connected to the driving motor. A reciprocating groove 19 is provided on the outer surface of the driving shaft 2, and a sliding ball 20 is slidably connected in the reciprocating groove 19. The sliding ball 20 is fixedly connected to the center of the movable plate 3. When the driving motor drives the driving shaft 2 to rotate, the movable plate 3 can be driven to reciprocate on the outer surface of the driving shaft 2 through the sliding connection between the reciprocating groove 19 and the sliding ball 20.

[0031] In this embodiment, Figure 1 and Figure 2 As shown, the upper end surface of the lifting plate 7 is provided with a card slot 14, and the card block 15 is clamped in the card slot 14, and a cross plate 10 is fixedly connected between the card blocks 15. Connecting columns 13 are symmetrically inserted and slid through the cross plate 10, and a sponge plate 9 is fixedly connected between the lower ends of the connecting columns 13. By setting the cross plate 10 to be installed on the lifting plate 7 in a clamping manner, the cross plate 10 can be removed from the cleaning box 1 when the sample tube is placed on the fixing frame 8, so as to facilitate the placement of the sample tube and avoid the existence of the sponge plate 9 blocking the placement of the sample tube.

[0032] In this embodiment, Figure 1 As shown, a threaded rod 11 is rotatably connected at the center of the upper end surface of the sponge board 9, and the threaded rod 11 penetrates and is rotatably connected to the horizontal plate 10. A knob 12 is fixedly connected to the upper end of the threaded rod 11. By setting the threaded rod 11 above the sponge board 9, the position of the sponge board 9 can be changed in real time, so that the sponge board 9 can be adapted to sample tubes of different lengths, thereby increasing the application range of the sponge board 9 and facilitating the cleaning of sample tubes of different specifications.

[0033] The effects achieved by this embodiment are as follows: in the prior art, the existing cleaning method only inverts the sample tube and uses the water pipe 6 to flush the inside of the sample tube to clean the sample tube, and because the sample tube and the water pipe 6 are in a relatively static state, the contact area between the sample tube and the water source will be single, resulting in uneven cleaning of the inside of the sample tube, resulting in some impurities remaining in the sample tube after cleaning, and cross-contamination with environmental samples during subsequent use, which is not conducive to sample sampling and detection. Compared with the prior art, the water source sprayed by the water pipe 6 can be in more sufficient contact with the inner surface of the sample tube, so that the cleaning liquid covers a wider area on the inner wall of the sample tube, thereby increasing the contact area between the water and the tube wall, and improving the cleaning effect of the sample tube. In addition, by reciprocatingly shaking the sample tube, it can also help the water or cleaning liquid to be evenly distributed inside the sample tube, so that the liquid can form a liquid circulation inside the sample tube to wash away the pollutants from the tube wall, thereby achieving more uniform cleaning;

[0034] Secondly, by setting the sponge plate 9 above the fixing frame 8, the sponge plate 9 can be mutually connected with the sample tube during the cleaning process of the sample tube, so that the sample tube can be tightly connected to the fixing frame 8, and it is avoided that when the fixing frame 8 is subsequently swung, the sample tube shakes on the fixing frame 8, causing the sample tube and the fixing frame 8 to collide, resulting in the sample tube being broken, thereby strengthening the protection of the sample tube and reducing the risk of damage to the sample tube during cleaning.

[0035] The working process and principle involved in the overall content of the above embodiment are as follows:

[0036] When the staff needs to clean the sample tube, first take out the cross plate 10, and take out the blocks 15 connected on both sides of the cross plate 10 from the slots 14 opened on the upper end surface of the lifting plate 7, so as to disassemble the cross plate 10 from between the lifting plates 7. When the lifting plates 7 are disassembled, the staff can insert the sample tube upside down on the fixing frame 8, and then take out the cross plate 10 again, and insert the blocks 15 connected on both sides of the cross plate 10 into the slots 14, so that the sponge plate 9 connected below the cross plate 10 and the sample tube are mutually contacted and connected, so that the sample tube can be tightly connected to the fixing frame 8, so as to avoid the sample tube shaking on the fixing frame 8 when the fixing frame 8 is subsequently swung, causing the sample tube to collide with the fixing frame 8, resulting in the sample tube being broken, thereby strengthening the protection of the sample tube and reducing the risk of damage to the sample tube during cleaning;

[0037] When the sponge board 9 moves to the top of the cleaning box 1 without contacting the sample tube, the staff can turn the knob 12 to drive the threaded rod 11 to rotate. The threaded rod 11 and the cross plate 10 are threadedly connected, and the threaded rod 11 can slide downward on the cross plate 10, thereby driving the sponge board 9 rotatably connected to the lower end of the threaded rod 11 to descend, and the position of the sponge board 9 is changed in real time, so that the sponge board 9 can be adapted to sample tubes of different lengths, thereby increasing the application range of the sponge board 9, so as to facilitate the cleaning of sample tubes of different specifications;

[0038] When the sponge plate 9 has stabilized the sample tube, the staff can connect the water pipe 6 so that the water source is sprayed into the sample tube through the nozzle 16. At the same time, the driving motor is turned on to drive the driving shaft 2 to rotate synchronously on the side wall of the cleaning box 1. As the driving shaft 2 rotates, the position of the reciprocating groove 19 opened on the outer surface of the driving shaft 2 can be changed, so that the reciprocating groove 19 squeezes the sliding ball 20, pushing the sliding ball 20 to move along the path of the reciprocating groove 19, thereby driving the moving plate 3 connected to the sliding ball 20 to slide back and forth on the outer surface of the driving shaft 2. During the movement of the moving plate 3, the sliding column 4 can be used to push the slider 18 to slide back and forth in the sliding groove 17, driving the rotating connection on the side wall of the slider 18 The lower end of the connecting rod 5 moves back and forth, reciprocatingly changing the tilted position of the connecting rod 5, pushing the lifting plate 7 connected to the other end of the connecting rod 5 to slide back and forth on the inner wall of the cleaning box 1, thereby driving the fixed frame 8 connected between the lifting plates 7 to shake up and down, so that the water source sprayed from the water pipe 6 is in more full contact with the inner surface of the sample tube, so that the cleaning liquid covers a wider area on the inner wall of the sample tube, thereby increasing the contact area between the water and the tube wall, improving the cleaning effect of the sample tube, and by reciprocatingly shaking the sample tube, it can also help the water or cleaning liquid to be evenly distributed inside the sample tube, so that the liquid can form a liquid circulation inside the sample tube, flushing the pollutants from the tube wall, thereby achieving more uniform cleaning.
