DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Reference Figures 1-7 The present invention provides an intelligent protection device for a hydrogeological measuring instrument. The hydrogeological measuring instrument comprises a flange 1, a guide rod 2 fixedly connected to the flange 1, and a float 3 slidably arranged on the guide rod 2. The intelligent protection device comprises:

[0045] The protective sleeve 4 is fixedly connected to the flange 1, and covers the guide rod 2 and the float 3. The side wall of the protective sleeve 4 is provided with a plurality of water inlet grooves 5 in the circumferential direction;

[0046] The rotating disk 6 is rotatably arranged on the outer wall of the protective sleeve 4 along the circumferential direction of the protective sleeve 4. The rotating disk 6 is drivingly connected with an inner wall cleaning mechanism and a plurality of through-slot cleaning mechanisms. The inner wall cleaning mechanism abuts against the inner wall of the protective sleeve 4. The inner wall cleaning mechanism is used to clean the inner wall of the protective sleeve 4. The plurality of through-slot cleaning mechanisms correspond to the plurality of water inlet through-slots 5 one by one. The through-slot cleaning mechanism is used to clean the water inlet through-slots 5.

[0047] The driving member is used to drive the rotating disk 6 to rotate.

[0048] When the protective sleeve 4 and multiple water inlet grooves 5 are clogged after being soaked for a long time, the rotating disk 6 is driven to rotate by the driving member, and the rotating disk 6 drives the inner wall cleaning mechanism to rotate circumferentially along the inner wall of the protective sleeve 4. The inner wall cleaning mechanism cleans the inner wall of the protective sleeve 4 from impurities. At the same time, the rotating disk 6 drives the multiple groove cleaning mechanisms to clean the multiple water inlet grooves 5 from impurities, so that the float 3 can slide smoothly in the protective sleeve 4 while maintaining the circulation effect of the water inlet grooves 5. The measuring instrument can be cleaned without disassembling the measuring instrument, so that the measuring instrument maintains high-precision operating efficiency.

[0049] In one embodiment of the present invention, the inner wall cleaning mechanism comprises:

[0050] A connecting rod 7 is fixedly connected to the rotating disk 6;

[0051] The first cleaning roller 8 abuts against the inner wall of the protective sleeve 4, and the first cleaning roller 8 is connected to the connecting rod 7 through a first reciprocating lifting mechanism;

[0052] The telescopic rod 9 has a telescopic end fixedly connected to one end of the first cleaning roller 8 close to the flange 1. The fixed end of the telescopic rod 9 is fixedly connected to a first gear 10. The first gear 10 is meshed with a first gear ring 11. The first gear ring 11 is circumferentially fixedly connected to the inner wall of the protective sleeve 4.

[0053] When the rotating disk 6 rotates, the first cleaning roller 8 is driven to rotate along the circumferential direction of the inner wall of the protective sleeve 4 through the connecting rod 7. At the same time, the first gear 10 cooperates with the first gear ring 11 to drive the first cleaning roller 8 to rotate through the telescopic rod 9. At the same time, the first reciprocating lifting mechanism cooperates with the telescopic rod 9 to make the first cleaning roller 8 move up and down, so that the first cleaning roller 8 can realize the cleaning state of self-rotation and lifting, thereby improving the cleaning effect of the inner wall of the corresponding protective sleeve 4.

[0054] In one embodiment of the present invention, the first reciprocating lifting mechanism comprises:

[0055] The lifting groove 12 is coaxially arranged with the first cleaning roller 8 and is opened at an end of the first cleaning roller 8 away from the flange 1;

[0056] A first reciprocating screw rod 13 is fixedly connected to the connecting rod 7. The first reciprocating screw rod 13 is coaxially arranged with the lifting groove 12 and is located inside the lifting groove 12;

[0057] The first reciprocating nut 14 is fixedly connected in the lifting groove 12 , and the first reciprocating nut 14 is transmission-connected to the first reciprocating screw rod 13 .

[0058] When the first cleaning roller 8 rotates, the first reciprocating nut 14 is driven to rotate synchronously. The first reciprocating nut 14 cooperates with the first reciprocating screw rod 13 to enable the first reciprocating nut 14 to move up and down reciprocatingly, and then the first reciprocating nut 14 drives the first cleaning roller 8 to move up and down reciprocatingly.

[0059] In one embodiment of the present invention, a sealing ring 15 is fixedly connected to the end of the lifting groove 12 and abuts against the side wall of the first reciprocating screw rod 13 . The sealing ring 15 is used to improve the sealing effect at the end of the lifting groove 12 to prevent water from penetrating into the lifting groove 12 .

A plurality of second cleaning rollers 19 and a plurality of circles of moving blades 20 located in the water inlet groove 5 are fixedly connected to the rotating shaft 18 .

[0063] When the rotating disk 6 rotates, the cleaning rod 16 is moved reciprocatingly by the second reciprocating lifting mechanism, so that the cleaning rod 16 drives multiple support rods 17 to move synchronously, and the support rods 17 drive the rotating shaft 18 and the second cleaning roller 19 to move synchronously. When the rotating shaft 18 moves, the blades 20 interact with the water, so that the blades 20 drive the rotating shaft 18 to rotate, and then the rotating shaft 18 drives the second cleaning roller 19 to rotate to clean the water inlet groove 5.

[0064] In one embodiment of the present invention, the second reciprocating lifting mechanism comprises:

[0065] A second reciprocating screw rod 21 is rotatably connected to the outer side wall of the protective sleeve 4;

[0066] The second reciprocating nut 22 is transmission-connected to the second reciprocating screw rod 21, and the second reciprocating nut 22 is fixedly connected to the cleaning rod 16;

[0067] The second gear 23 is fixedly connected to the second reciprocating screw rod 21 . The second gear 23 is meshed with a second gear ring 24 . The second gear ring 24 is fixedly connected to the rotating disk 6 .

[0068] When the rotating disk 6 rotates, it drives a plurality of second gears 23 to rotate through the second gear ring 24. Further, the second gears 23 drive the second reciprocating lead screw 21 to rotate. With the cooperation of the second reciprocating lead screw 21 and the second reciprocating nut 22, the second reciprocating nut 22 drives the cleaning rod 16 to perform reciprocating lifting and lowering movements.

[0069] Further, a guiding and limiting rod is fixedly connected to the side wall of the second reciprocating nut 22. The guiding and limiting rod is slidably engaged with a guiding and limiting groove formed on the outer side wall of the protective sleeve 4. The guiding and limiting rod and the guiding and limiting groove limit the second reciprocating nut 22, enabling the second reciprocating nut 22 to achieve translation.

[0070] In an embodiment of the present invention, the driving member includes:

[0071] A motor 25, fixedly installed on the outer side wall of the protective sleeve 4;

[0072] A third gear 26, connected to the output shaft of the motor 25;

[0073] A third gear ring 27, meshing with the third gear 26. The third gear ring 27 is circumferentially fixedly connected to the rotating disk 6.

[0074] The motor 25 drives the third gear 26 to rotate. Further, the cooperation of the third gear 26 and the third gear ring 27 causes the rotating disk 6 to rotate.

[0075] Further, the motor 25 is connected to an external power source and is intelligently operated through a control controller. This is prior art and will not be elaborated here.

[0076] In an embodiment of the present invention, the first gear ring 11 includes a ring body 1101. An annular groove 1102 is circumferentially formed on the inner circumference of the ring body 1101. The upper and lower end faces of the annular groove 1102 are respectively abutted against the upper and lower end faces of the first gear 10. Meshing teeth for meshing with the first gear 10 are circumferentially arranged in the annular groove 1102.

[0077] The annular groove 1102 can confine the position of the first gear 10, enabling the first gear 10 to stably rotate along the first gear ring 11.

[0078] In an embodiment of the present invention, the telescopic rod 9 includes an outer cylinder 91 and an inner rod 92 that are slidably engaged. The outer cylinder 91 is fixedly connected to the first gear 10, and the inner rod 92 is fixedly connected to the first cleaning roller 8. A plurality of limiting strips 93 are fixedly connected to the inner rod 92. A plurality of limiting chutes 94 are formed on the inner side wall of the outer cylinder 91. The plurality of limiting chutes 94 correspond to the plurality of limiting strips 93 one by one and are slidably engaged.

[0079] The limiting strip 93 and the limiting sliding groove 94 can prevent the outer cylinder 91 and the inner rod 92 from rotating relative to each other, so that the outer cylinder 91 and the inner rod 92 can only expand and contract, and further enable the rotation of the first gear 10 to drive the first cleaning roller 8 to rotate.

[0080] In an embodiment of the present invention, one end of the protective sleeve 4 away from the flange 1 is open, and the connecting rod 7 is a U-shaped structure and extends into the protective sleeve 4 through the open end of the protective sleeve 4, which can prevent interference between the connecting rod 7 and the protective sleeve 4 when the connecting rod 7 rotates.
