[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1, with reference to Figures 1 to 7 , which is the first embodiment of the present invention, provides a medium parameter measurement telescopic cleaning device, which can automatically replace the nozzle 15 during telescopic cleaning, so that the cleaning effect is more comprehensive. It includes a cleaning component, including a frame 10, an electrode sheath 12 is fixedly connected to the frame 10 through a telescopic portion 11, an electrode body 13 is provided on the electrode sheath 12, a support ring 14 is fixedly connected to the frame 10 through a support frame, and two nozzles 15 are provided on the support ring 14; a nozzle replacement component includes a plurality of vertical slots 20 provided on the support ring 14, and the plurality of vertical slots 20 are provided on the support ring 14. A guide portion 21 for shifting the nozzle 15 is provided inside, a mounting frame 22 is provided outside the nozzle 15, a power portion 23 for moving the nozzle 15 is provided on the mounting frame 22, a one-way portion 24 for ensuring accurate displacement of the nozzle 15 is provided in the vertical groove 20, two arc-shaped openings 25 are provided on the support ring 14, an elastic portion 26 for resetting the nozzle 15 is provided on the arc-shaped opening 25, a first annular groove 27 is provided in the vertical groove 20, and a blocking portion 28 is provided in the first annular groove 27; a water spray switching component includes a water spray portion 30 arranged on the nozzle 15, and a toggle portion 31 for switching the water spray form on the mounting frame 22.

[0030] Specifically, a sampling flow cell is also provided at the lower end of the frame 10 for storing the medium. At the same time, an installation column is provided on one side of the frame 10, and an instrument box 16 is fixedly connected to the column. The electrode body 13 is immersed in the medium during measurement. When cleaning is required, the cylinder drives the electrode body 13 to rise to start flushing. After the flushing is completed, the electrode body 13 descends with the cylinder and immerses into the medium to start a new measurement. There are two cleaning nozzles 15, which are oppositely installed. When cleaning the electrode body 13, the liquid coming out of the nozzles 15 is a water-vapor mixture, achieving atomization and making the cleaning effect better. The outer end of the nozzle 15 here is connected to a water pipe to supply water to the nozzle 15, and there is a certain water pressure in the water pipe to ensure the spraying effect of the nozzle 15. Three knobs are equipped outside the instrument box 16 here: automatic / manual, manual cleaning start / stop, and manual cylinder retraction / extension. Through the knobs, the manual / automatic mode can be switched, and the cylinder telescoping and flushing start / stop can be controlled.

[0031] Furthermore, the telescopic part 11 includes a fixed bracket 111 fixedly connected to the frame 10. A telescopic cylinder 112 is fixedly connected to the fixed bracket 111. The end of the telescopic cylinder 112 is fixedly connected with a limit clip 113, and the limit clip 113 cooperates with the electrode sheath 12; the guiding part 21 includes inclined grooves 211 arranged on a plurality of vertical grooves 20. Extended grooves 212 penetrating the support ring 14 are communicated and arranged on the plurality of vertical grooves 20, and the inclined groove 211 on one vertical groove 20 is communicated with the adjacent vertical groove 20.

[0032] Among them, the limit clip 113 here can carry the electrode sheath 12. Of course, for the stability of the limit, the limit clip 113 and the electrode sheath 12 can also be fixed through the cooperation of bolts and nuts. It should be noted that the range within which the two nozzles 15 can move here is 180°. The two nozzles 15 cooperate to be able to clean the entire side wall of the electrode body 13.

[0033] Preferably, the power part 23 includes a moving rod 231 fixedly connected to the installation frame 22. The moving rod 231 cooperates with the vertical groove 20. The telescopic end of the telescopic cylinder 112 is fixedly connected with a disc 232. A second annular groove 233 in a T shape is arranged on the disc 232, and a T-shaped plate fixed to the installation frame 22 is slidably connected in the second annular groove 233; the one-way part 24 includes an outward expansion groove 241 arranged in the vertical groove 20 and the inclined groove 211. A wedge block 242 is slidably connected in the outward expansion groove 241, and the wedge block 242 is elastically connected to the inner wall of the outward expansion groove 241 through a first spring 243. [[ID=...]]

[0034] It should be noted that the setting of the wedge block 242 here enables the moving rod 231 not to be blocked when moving downward in the vertical groove 20, and to be blocked when moving upward, so as to ensure that the moving rod 231 moves into the inclined groove 211, thereby realizing unidirectional movement. It should be noted here that the wedge block 242 is not provided in the vertical groove 20 corresponding to the initial positions of the two moving rods 231, so as not to affect the phenomenon that the mounting frame 22 cannot move upward when rotating 180°.

[0035] During use, when the electrode body 13 needs to be cleaned, the telescopic rod shortens, causing the electrode sheath 12 to move, driving the electrode body 13 to move into the support ring 14, and then water is supplied to the nozzle 15 to wash the side wall of the electrode body 13. During the washing, the telescopic cylinder 112 reciprocates, causing the electrode body 13 to move up and down, making the cleaning more comprehensive. When the telescopic cylinder 112 reciprocates, it will drive the disc 232 to move downward, the T-shaped plate to move downward, the mounting frame 22 to move downward, and the moving rod 231 to move downward. At this time, the moving rod 231 slides downward in the vertical groove 20. Here, the inclined surface of the wedge block 242 faces upward, so when the moving rod 231 moves downward, the wedge block 242 retracts into the extension groove and does not block the downward movement of the moving rod 231. When the telescopic cylinder 112 contracts, the moving rod 231 completely moves to the lower side of the wedge block 242. When the moving rod 231 moves upward, since the non-inclined surface of the wedge block 242 cooperates with the moving rod 231, the moving rod 231 cannot move upward at this time and can only enter the inclined groove 211. When the moving rod 231 enters the inclined groove 211, it will cause the moving rod 231 to move upward and at the same time move into the adjacent vertical groove 20, thereby driving the mounting frame 22 to shift. Here, the T-shaped plate slides in the second annular groove 233 to guide the mounting frame 22. When the mounting frame 22 moves, it will drive the position of the nozzle 15 to change until the moving rod 231 moves into the adjacent vertical groove 20, and then the telescopic cylinder 112 continues to move upward to wash the side wall of the electrode body 13. Repeating this operation can drive the nozzle 15 to continuously change its position during the lifting and washing process of the electrode body 13, washing the entire side wall of the electrode body 13, making the cleaning more complete.

[0036] In summary, by setting the nozzle position-changing component, during the lifting and washing process of the electrode body 13, the two nozzles 15 can continuously change their positions within a range of 180°, so as to be able to wash the entire side wall of the electrode body 13, making the cleaning effect of the electrode body 13 better.

[0037] Example 2, refer to Figures 1 to 9, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an elastic part 26 of the telescopic cleaning device for measuring medium parameters, solving the problem of how to automatically reset the nozzle 15. It includes an elastic part 26, which includes a through hole 261 provided on the inner wall of the arc-shaped opening 25. The through hole 261 is communicated with a receiving cavity 262. A sliding plate 263 is slidably connected in the receiving cavity 262. An arc-shaped plate 264 fixed to the nozzle 15 is fixedly connected to the sliding plate 263. The sliding plate 263 is elastically connected to the inner wall of the receiving cavity 262 through an arc-shaped spring 265. The blocking part 28 includes a third annular groove 281 provided in the first annular groove 27. An electromagnet 282 is fixedly connected in the third annular groove 281. An iron ring 284 is elastically connected to the electromagnet 282 through a second spring 283. A plurality of pairs of stoppers 285 extending to the first annular groove 27 are fixedly connected to the iron ring 284. The plurality of pairs of stoppers 285 are respectively located on the left and right sides of the vertical groove 20.

[0038] Specifically, the arc-shaped spring 265 here has sufficient elasticity to ensure that the nozzle 15 can be reset. The rotation angle of the nozzle 15 is 180°, which can avoid the phenomenon of the water pipe on the nozzle 15 being wound. It should be noted that due to the inclined groove 211, when the moving rod 231 moves into the adjacent vertical groove 20, although the arc-shaped spring 265 has a tendency to reset, at this time, the moving rod 231 abuts against the inner wall of the vertical groove 20, which will block the reset of the arc-shaped spring 265. Of course, in order to ensure that the moving rod 231 will not reset, a structure identical to the elastic part 26 can also be provided in the inclined groove 211. Here, the arc-shaped plate 264 can guide the nozzle 15 to avoid the nozzle 15 from shifting during movement. The initial positions of the two moving rods 231 correspond to two vertical grooves 20. When approaching a 180° rotation, the two moving rods 231 will change positions. When changing positions and entering the last inclined groove 211, the position of this inclined groove 211 is higher than other inclined grooves 211. Therefore, when the moving rod 231 moves upward, there will be no blocking phenomenon. At the same time, since the arc-shaped plate 264 has a limiting effect on the nozzle 15 here, when resetting, the nozzle 15 will not move more than 180°.

[0039] In use, in the initial state, the electromagnet 282 is de-energized. Under the action of the second spring 283, multiple pairs of stoppers 285 on the iron ring 284 are located on both sides of the vertical groove 20. During the process that the moving rod 231 moves along the inclined groove 211 into the adjacent vertical groove 20 and finally into the first arc groove, the movement of the nozzle 15 drives the movement of the arc plate 264, and the second spring 283 is compressed. At this time, the second spring 283 rebounds, driving the arc plate 264 and the nozzle 15 to have a tendency to reset, and the moving rod 231 has a tendency to reset. Due to the blockage of the stopper 285, when it is in the vertical groove 20, the phenomenon that the moving rod 231 resets from the first annular groove 27 will not occur, ensuring that the moving rod 231 can continue to move to change the position of the nozzle 15. When the nozzle 15 is approaching 180° (since the arc spring 265 cannot be completely compressed, so it is only approaching 180°. Here, because the nozzle 15 has a certain spraying range, it will not affect the cleaning of the entire side wall of the electrode body), the electromagnet 282 is energized to attract the iron block, so that the stopper 285 disengages from the first annular groove 27. At this time, when the moving rod 231 moves to the vertical groove 20 and finally into the first annular groove 27, under the action of the second spring 283, the moving rod 231 resets, driving the nozzle 15 to reset for changing the position and spraying water next time.

[0040] In summary, by setting the elastic part 26 and the blocking part 28, during the process of changing the position of the nozzle 15, the stopper 285 blocks the moving rod 231 from resetting from the first annular groove 27, thus preventing the guiding rod from resetting in advance and causing the phenomenon that the nozzle 15 cannot continue to change positions.

[0041] Example 3, referring to Figures 1 to 10 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a water spraying switching component of the medium parameter measurement telescopic cleaning device, which solves the problem of how to switch the water spraying form to achieve high-pressure and large-range water spraying. It includes a water spraying part 30, which includes a water spraying disc 301 arranged at the front end of the nozzle 15. A plurality of water spraying holes 302 are arranged on the water spraying disc 301. A water blocking cover 304 with a plurality of spraying holes 303 is rotatably connected to the water spraying disc 301. The plurality of spraying holes 303 on the water blocking cover 304 are divided into outer-ring spraying holes 303 and inner-ring spraying holes 303. The outer-ring spraying holes 303 and the inner-ring spraying holes 303 are arranged in a staggered manner, and the number of outer-ring spraying holes 303 is greater than the number of inner-ring spraying holes 303.

[0042] Specifically, the outer-ring spraying holes 303 and the inner-ring spraying holes 303 on the water blocking cover 304 are arranged in a staggered manner, so as to rotate the water blocking cover 304.

[0043] Furthermore, the shifting part 31 includes a cylinder 311 fixedly connected to the water shield 304, two shifting blocks 312 are fixedly connected to the cylinder 311, a first arc block 313 is fixedly connected to the lower end of the mounting frame 22, a lifting plate 315 is elastically connected to the mounting frame 22 through a third spring 314, a second arc block 316 is fixedly connected to the lifting plate 315, and the first arc block 313, the second arc block 316 and the shifting block 312 are all provided with cutting edges 317.

[0044] When in use, when the mounting frame 22 is downward, the inner ring spray holes 303 of the water shield 304 are aligned with the spray holes 302 on the water spray plate 301. At this time, the inner ring spray holes 302 spray water. Since the number of the inner ring spray holes 303 is small, the water pressure is large, which makes it easy to wash off the adhesive material on the side wall of the electrode body 13. When the mounting frame 22 moves to the lower end, the second arc block 316 at the upper end moves downward. When the moving rod 231 moves to the lower end of the vertical slot 20 and connects with the inclined slot 211, When the water pipe is turned, the mounting frame 22 does not continue to move downward, the second arc block 316 abuts against the upper end of the shift block 312, and the setting of the cutting edge 317 can avoid the second arc block 316 and the shift block 312 from getting stuck. The second arc block 316 can push the shift block 312 to deflect counterclockwise (from the direction of the water pipe, the same below), so that the cylinder 311 rotates counterclockwise, thereby rotating the water shield 304 counterclockwise, so that the outer ring of the spray hole 303 is facing the water spray hole 302. When the second spring 314 and the lifting plate 315 are arranged, the guide rod 231 is moved into the extension groove 212 to soak the electrode body 13, and the third spring 314 contracts, so that the lifting plate 315 has a moving distance to avoid the second arc plate 264 and the cylinder 311 from getting stuck.

[0045] In summary, by setting up a water spray switching component, the water spray shape of the nozzle 15 can be switched when the mounting frame 22 moves up and down, so that the water pressure is greater when the electrode body 13 is downward, and there is a larger cleaning range when the electrode body 13 is upward, resulting in a better cleaning effect.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
