Description

Technical Field

[0001] The invention belongs to the technical field of water quality detection and relates to a fishery water quality detection robot. Background Art

[0002] The quality of water directly affects the health and economic benefits of fish. A good water quality environment can provide a good growth environment for fish and is also an important measure to protect the environment. Through water quality monitoring, we can accurately warn of water quality abnormalities, optimize aquaculture management, and protect the ecological environment.

[0003] When testing water quality, in order to prevent a large amount of impurities from being left on the detection probe and affecting the subsequent detection accuracy, a filter is usually set to isolate the impurities. However, when the filter is used to remove impurities, the impurities and aquatic flocs in the water will be retained on the filter, causing the filter to be blocked, which not only affects the water permeability of the filter, but also the flocs retained on the surface of the filter will affect the detection accuracy of the water quality. Although there is a cleaning structure for the filter in the prior art, it generally cleans the surface of the filter, and cannot clean the filter holes of the filter.

[0035] like Figure 1-Figure 13 As shown, the technical solution adopted by the present invention is as follows: a fishery water quality detection robot includes a hull 1, a filter cartridge 18 and a cleaning mechanism.

[0038] The lower end of the hull 1 is provided with a groove 6, and a slide plate 8 is arranged to move up and down in the groove 6. Specifically, the hull 1 is vertically fixedly connected with a first telescopic rod 9, and the telescopic end of the first telescopic rod 9 is vertically downward and fixedly connected with the slide plate 8.

[0039] The lower end surface of the slide plate 8 is concentrically fixedly connected with a fixing column 46, the fixing column 46 is fixedly connected with a fixing rod 27, and the lower end of the fixing rod 27 is fixedly connected with the bottom plate 7. The filter cartridge 18 is fixedly mounted on the bottom plate 7, and the filter cartridge 18 and the fixing rod 27 are concentrically arranged.

[0040] The fixed column 46 is connected to the sealing sleeve 25 for vertical movement, and the sealing sleeve 25 is provided with a detection head 28. Specifically, the fixed column 46 is embedded with a second telescopic rod 21, and the telescopic end of the second telescopic rod 21 is vertically downward and fixedly connected to the sealing sleeve 25. The lower end of the sealing sleeve 25 is open, and the upper end of the sealing sleeve 25 is provided with a through hole for sealing and sliding cooperation with the fixed rod 27. Water in the water source enters the filter cartridge 18, and the sealing sleeve 25 is moved downward by the second telescopic rod 21, so that the lower end of the sealing sleeve 25 is fitted with the bottom plate 7, and the sample to be tested is sealed in the sealing sleeve 25, and the detection head 28 detects the water in the sealing sleeve 25.

[0041] A pumping hole 26 is provided at the lower end of the fixing rod 27, and a connecting pipe 10 is installed in the fixing rod 27, and the lower end of the connecting pipe 10 is connected to the pumping hole 26. A water pump is installed in the hull 1, and the upper end of the connecting pipe 10 is connected to the water suction end of the water pump. A sample storage barrel 5 is provided on the hull 1, and the water outlet end of the water pump is connected to the sample storage barrel 5. There are multiple sample storage barrels 5, and the water pump extracts the sample in the sealing sleeve 25, and injects the samples at different positions into different sample storage barrels 5. In this way, the storage of the samples is realized, which is convenient for the subsequent staff to process the samples.

[0042] The cleaning mechanism is used to clean the filter cartridge 18 to prevent the floccules adhering to the filter cartridge 18 from affecting the water quality detection accuracy and the water flow efficiency of the filter cartridge 18. In this embodiment, there are four groups of cleaning mechanisms, and the four groups of cleaning mechanisms are evenly distributed along the axis of the filter cartridge 18.

[0043] The cleaning mechanism includes a mounting plate 14 , a first cleaning rod 29 and a second cleaning rod 31 .

[0044] A second rotating ring 13 is rotatably mounted on the lower end surface of the slide plate 8. Specifically, a motor 11 is embedded and fixedly mounted in the slide plate 8, the motor shaft of the motor 11 is vertically downward, a second gear 36 is coaxially fixedly connected to the motor shaft of the motor 11, a second gear ring 23 is coaxially fixedly connected to the inner side of the second rotating ring 13, and the second gear ring 23 is meshed with the second gear 36. The lower end of the second rotating ring 13 is sealed and rotatably connected to the upper end of the filter cartridge 18.

[0045] The first rotating ring 12 is elastically rotatably mounted in the second rotating ring 13. A rotating cavity is provided in the second rotating ring 13, and the first rotating ring 12 is rotatably arranged in the rotating cavity. Both the first rotating ring 12 and the second rotating ring 13 are coaxially arranged with the filter cartridge 18. Fig. 9 , Fig.10As shown, a plurality of first clearance grooves 33 are provided on the top wall of the rotating cavity, and the plurality of first clearance grooves 33 are evenly distributed around the axis of the first rotating ring 12, and a circular arc block 40 is slidably arranged in each first clearance groove 33, and a first spring 32 is fixedly connected to the front side of the circular arc block 40 in the clockwise direction, and the first spring 32 is fixedly connected to the end wall of the first clearance groove 33. The circular arc block 40 is fixedly connected to the first rotating ring 12. In this embodiment, there are four first clearance grooves 33.

[0046] Four through holes 16 are evenly formed on the circumferential surface of the second rotating ring 13 , and the four through holes 16 correspond to the four cleaning mechanisms one by one.

[0047] The mounting plate 14 passes through the corresponding through hole 16. One end of the mounting plate 14 located inside the filter cartridge 18 is fixedly connected to the first cleaning rod 29, and one end of the mounting plate 14 located outside the filter cartridge 18 is fixedly connected to the second cleaning rod 31.

[0048] like Fig.11 , Fig.12 As shown, the mounting plate 14 is elastically slidably connected to the first rotating ring 12, and the mounting plate 14 slides along the radial direction of the first rotating ring 12. Slide blocks 42 are fixedly connected to both sides of the mounting plate 14. The slide blocks 42 are slidably arranged in the slide grooves 43 on the fixed block 15, and the fixed block 15 is fixedly connected to the first rotating ring 12. A second spring 41 is fixedly connected between the slide block 42 and the end wall of the slide groove 43.

[0049] like Fig.13 As shown, the second cleaning rod 31 is provided with a plurality of second clearance grooves 45, in which a rotating rod 44 is rotatably mounted, and the rotating rod 44 is fixedly connected with rake teeth 17. A torsion spring is sleeved on the rotating rod 44, and the torsion spring is fixedly connected between the second cleaning rod 31 and the rotating rod 44. A plurality of rake teeth 17 are arranged from top to bottom along the second cleaning rod 31. When the first rotating ring 12 rotates around the axis of the filter cartridge 18, the cleaning mechanism rotates around the axis of the filter cartridge 18 synchronously, and the rake teeth 17 clean the outer surface of the filter cartridge 18.

[0050] A plurality of cleaning teeth 30 are fixedly mounted on the first cleaning rod 29. The filter cartridge 18 has a plurality of groups of filter holes, and the plurality of cleaning teeth 30 on the first cleaning rod 29 correspond one by one to the plurality of filter holes in the same group. When the mounting plate 14 slides outward along the fixing block 15, the cleaning teeth 30 are inserted into the corresponding filter holes to clean the filter holes.

[0051] A limit ring 37 is unidirectionally rotatably provided on the fixed column 46, and the limit ring 37 is coaxially arranged with the filter cartridge 18. Four limit grooves 39 are evenly provided on the inner side of the limit ring 37, and the four limit grooves 39 correspond to the four cleaning mechanisms one by one. The end of the mounting plate 14 close to the first cleaning rod 29 is vertically rotatably connected to the limit column 38, and the limit column 38 cooperates with the corresponding limit groove 39. Initially, the second spring 41 is in a stretched state, and under the action of the second spring 41, the limit column 38 abuts against the inner side of the limit ring 37. As the first rotating ring 12 rotates, when the limit column 38 is opposite to the limit groove 39, under the action of the second spring 41, the first rotating ring 12 slides outward along the fixed block 15, and the limit column 38 enters the limit groove 39, thereby inserting the cleaning tooth 30 into the corresponding filter hole.

[0052] The one-way bearing 22 is mounted on the fixed column 46, and the inner ring of the one-way bearing 22 is fixedly connected to the fixed column 46. The outer ring of the one-way bearing 22 is coaxially fixedly connected to the third rotating ring 19, and the limiting ring 37 is coaxially fixedly connected to the third rotating ring 19. Under the action of the one-way bearing 22, the third rotating ring 19 and the limiting ring 37 can only rotate counterclockwise.

[0053] The first gear ring 20 is coaxially fixedly mounted on the outer ring of the one-way bearing 22, and the first gear ring 20 is meshed with the first gear 35, and the first gear 35 is rotatably mounted on the slide plate 8. The inner side of the second rotating ring 13 is coaxially fixedly connected with an incomplete gear ring 24, and the incomplete gear ring 24 cooperates with the first gear 35. When the second rotating ring 13 rotates clockwise, the incomplete gear ring 24 rotates. When the incomplete gear ring 24 meshes with the first gear 35, the first gear ring 20 rotates counterclockwise, and the limit ring 37 rotates counterclockwise, thereby making the limit groove 39 at a position corresponding to the next group of filter holes.

[0054] The second rotating ring 13 is provided with a driving assembly for making the limiting column 38 escape from the limiting groove 39. The driving assembly includes a guide ring 34, which is fixedly connected to the second rotating ring 13. A guide surface 341 and a third clearance groove 342 are provided on the guide ring 34, and the guide surface 341 and the third clearance groove 342 are connected. The third clearance groove 342 is located at the front end of the guide surface 341 in the clockwise direction, and the end of the guide surface 341 close to the third clearance groove 342 is inclined in the direction away from the axis of the second rotating ring 13. There are four guide rings 34, and the four guide rings 34 correspond to the four limiting columns 38 one by one. The third clearance groove 342 is arranged in cooperation with the through hole 16. When the mounting plate 14 is located at the front end of the through hole 16 in the clockwise direction, the limiting column 38 is opposite to the third clearance groove 342.

[0055] The second rotating ring 13 drives the first rotating ring 12 and the cleaning mechanism to rotate clockwise, and the limiting column 38 moves along the limiting ring 37. When the limiting column 38 is opposite to the limiting groove 39, under the action of the second spring 41, the mounting plate 14 slides outward, and the limiting column 38 moves into the limiting groove 39. Afterwards, because the limiting ring 37 cannot rotate clockwise, under the limiting action of the limiting groove 39, the first rotating ring 12 and the cleaning mechanism stop rotating. As the second rotating ring 13 rotates, the mounting plate 14 slides toward the other end of the through hole 16, the arc block 40 slides in the first giving way groove 33, and the first spring 32 is compressed. The guide ring 34 rotates with the second rotating ring 13. Under the action of the guide surface 341, the mounting plate 14 slides inward along the fixing block 15, so that the limiting column 38 gradually disengages from the limiting groove 39. When the limiting column 38 disengages from the limiting groove 39, under the action of the first spring 32, the first rotating ring 12 rotates rapidly clockwise, and the rake teeth 17 rotate around the corresponding rotating rod 44. Under the action of the water flow, the flocs on the rake teeth 17 fall off.

[0056] Working principle: Initially, under the action of the second spring 41, the limiting column 38 abuts against the inner side of the limiting ring 37. The rake teeth 17 cooperate with the outer surface of the filter cartridge 18. Under the action of the first spring 32, the arc block 40 abuts against the front end of the first clearance groove 33 in the clockwise direction. The limiting column 38 is opposite to the third clearance groove 342. The limiting groove 39 is at a position corresponding to one group of filter holes. The mounting plate 14 is at the front end of the through hole 16 in the clockwise direction.

[0057] When in use, place the hull 1 on the water surface to be tested, and then move the hull 1 to the position to be tested. After that, start the first telescopic rod 9 to move the slide 8 downward, and move the filter cartridge 18 downward to the sampling depth. Water enters the filter cartridge 18, and the filter cartridge 18 filters the debris and flocs in the water. Then, the sealing sleeve 25 is moved downward by the second telescopic rod 21, and the sample is sealed in the sealing sleeve 25. The sample in the sealing sleeve 25 is tested by the detection head 28. After that, start the water pump, and the water pump injects the sample in the sealing sleeve 25 into the sample storage barrel 5 to store the sample.

[0058] When the filter cartridge 18 needs to be cleaned, the motor 11 is started, the second gear 36 rotates, and the second gear 36 drives the second rotating ring 13 to rotate clockwise through the second gear ring 23, and the first rotating ring 12 and the cleaning mechanism rotate clockwise synchronously, and at this time, the water resistance is not enough to make the rake teeth 17 overcome the resistance of the torsion spring and rotate around the rotating rod 44. The rake teeth 17 move along the outer surface of the filter cartridge 18 and then clean the debris and flocculent adhering to the outer surface of the filter cartridge 18. In this process, the limit column 38 slides along the inner side of the limit ring 37, and the limit ring 37 is stationary because the limit ring 37 cannot rotate clockwise. When the limit column 38 is opposite to the limit groove 39, under the action of the second spring 41, the mounting plate 14 slides outward along the fixing block 15, the limit column 38 enters the limit groove 39, and the cleaning teeth 30 are inserted into the corresponding filter holes. The cleaning teeth 30 dredge and clean the filter holes. At the same time, the rake teeth 17 slide toward the outside of the filter cartridge 18 , which is conducive to the shedding of debris or flocs on the rake teeth 17 .

[0059] Afterwards, since the limiting column 38 is located in the limiting groove 39, the limiting ring 37 cannot rotate clockwise. Under the limiting action of the limiting ring 37, the cleaning mechanism and the first rotating ring 12 stop rotating. As the second rotating ring 13 rotates clockwise, the first spring 32 is compressed, the arc block 40 slides in the first clearance groove 33, and the mounting plate 14 slides along the through hole 16. The guide ring 34 rotates synchronously with the second rotating ring 13, and under the guiding action of the guide surface 341, the limiting column 38 gradually escapes from the limiting groove 39. When the limiting column 38 escapes from the limiting groove 39, under the action of the first spring 32, the first rotating ring 12 rotates rapidly clockwise, the cleaning mechanism rotates rapidly, the mounting plate 14 slides along the through hole 16, and the arc block 40 slides along the first clearance groove 33. Under the action of water resistance, the rake teeth 17 rotate around the rotating rod 44, and the end of the rake teeth 17 away from the second cleaning rod 31 is at the rear end of the water flow direction, so that the debris or flocs entangled on the rake teeth 17 fall off under the impact of the water flow.

[0060] When the mounting plate 14 is located at the front end of the through hole 16 in the clockwise direction, the rake teeth 17 are reset under the action of the torsion spring.

[0061] When the second rotating ring 13 rotates, the incomplete toothed ring 24 rotates accordingly, and when the incomplete toothed ring 24 meshes with the first gear 35, the first gear 35 drives the first toothed ring 20 to rotate counterclockwise, and the third rotating ring 19 and the limiting ring 37 rotate counterclockwise. The limiting ring 37 rotates counterclockwise by a certain angle, and then the limiting groove 39 is located at a position corresponding to the next group of filter holes, so as to facilitate the cleaning of the next group of filter holes.

[0062] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
