DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] Example: Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a multifunctional water area detection rod comprises a first-level telescopic sleeve rod 1, the first-level telescopic sleeve rod 1 is internally slidably connected with a second-level telescopic sleeve rod 2, the inner bottom surface of the second-level telescopic sleeve rod 2 is fixedly connected with a limited disc 7, the inner bottom surface of the second-level telescopic sleeve rod 2 is internally slidably connected with a third-level telescopic sleeve rod 3, the middle part of the inner bottom surface of the first-level telescopic sleeve rod 1 is rotatably connected with a first threaded rod 6, the first threaded rod 6 extends through and extends to one end outside the first-level telescopic sleeve rod 1 and is coaxially fixedly connected with a knob, the middle part of the bottom surface of the second-level telescopic sleeve rod 2 is threadedly connected with the first threaded rod 6, the outer sliding sleeve of the first threaded rod 6 is provided with a second threaded rod 8, and the outer wall of the second threaded rod 8 is threadedly connected with the bottom of the third-level telescopic sleeve rod 3;

[0035] Two first limit slide bars 4 are symmetrically fixedly connected between the inner bottom surface and the inner top surface of the primary telescopic sleeve rod 1, and the two first limit slide bars 4 are slidably connected to the bottom of the outer wall of the secondary telescopic sleeve rod 2. The first limit slide bar 4 guides and limits the movement of the secondary telescopic sleeve rod 2 inside the primary telescopic sleeve rod 1;

[0036] Two second limiting slide bars 5 are symmetrically fixedly connected between the inner top surface of the secondary telescopic sleeve 2 and the top surface of the limiting disk 7, and the two second limiting slide bars 5 are both slidably connected to the bottom of the outer wall of the tertiary telescopic sleeve 3. The second limiting slide bar 5 guides and limits the movement of the tertiary telescopic sleeve 3 inside the secondary telescopic sleeve 2.

[0038] A vertical slide groove is vertically opened on the outer wall of the first threaded rod 6, and a sliding block is fixedly connected to the bottom of the inner wall of the second threaded rod 8, and the sliding block is slidably connected to the vertical slide groove.

[0039] When this multifunctional water area detection rod is to be used, the first threaded rod 6 is driven to rotate by rotating the knob, and the rotating first threaded rod 6 drives the secondary telescopic sleeve rod 2 to move up. Since the vertical slide groove of the first threaded rod 6 is slidably connected with the slider on the second threaded rod 8, the second threaded rod 8 rotates synchronously with the first threaded rod 6. Moreover, because the annular slide groove of the limiting disk 7 is slidably connected with the annular slide plate 30 of the second threaded rod 8, the relative movement of the second threaded rod 8 and the secondary telescopic sleeve rod 2 in the vertical direction is limited, and the relative rotation between the second threaded rod 8 and the secondary telescopic sleeve rod 2 is not limited. That is, when the second threaded rod 8 rotates, the tertiary telescopic sleeve rod 3 will also move up synchronously, realizing the synchronous upward movement of the secondary telescopic sleeve rod 2 and the tertiary telescopic sleeve rod 3, and due to the self-locking property of the threaded rod, no additional limiting parts are required, and the locking between the primary telescopic sleeve rod 1, the secondary telescopic sleeve rod 2 and the tertiary telescopic sleeve rod 3 is achieved.

Further, the first transmission belt 15 drives the first driving pulley 13 and the first driven pulley 14 to rotate, and the first bevel gear 17 will rotate synchronously with the first driven pulley 14. Through the cooperation with the bevel gear ring on the bottom surface of the first annular disk 9, the first bevel gear 17 will drive the first annular disk 9 to rotate.

Through the cooperation with the bevel gear ring on the bottom surface of the second annular disk 11, the second bevel gear 22 will drive the second annular disk 11 to rotate. During the retraction process, the rotating second annular disk 11 will scrape off the impurities in the water adsorbed on the outer wall of the three-stage telescopic sleeve 3 through the second inclined scraper 12.

[0047] The first scraping mechanism and the second scraping mechanism are respectively installed with a first sealing mechanism and a second sealing mechanism, the first sealing mechanism includes a first stepped annular cavity opened inside the first annular disc 9, the upper half of the first stepped annular cavity is sealingly and slidably connected with a first annular piston 23, the top surface of the first annular piston 23 is fixedly connected with a plurality of first sliding rods 24 extending through and extending to the outside of the first annular disc 9, the outsides of the plurality of first sliding rods 24 are fixedly connected with the same first annular floating plate 25, and the outlet of the first stepped annular cavity in contact with the secondary telescopic sleeve 2 is fixedly connected with an elastic rubber sealing ring;

The internal air pressure of the first stepped annular cavity increases, and pressure will be applied to the rubber sealing ring, so that the rubber sealing ring and the outer wall of the secondary telescopic sleeve 2 are more tightly connected, thereby improving the sealing of the connection between the primary telescopic sleeve 1 and the secondary telescopic sleeve 2. It should be noted that the maximum moving distance of the first annular piston 23 cannot reach the lower half of the first stepped annular cavity, which can be achieved by controlling the length of the first slide rod 24.
