[0041] Embodiment 2

[0042] Please refer to Figures 1 to 9 The water level monitoring device comprises a box body 4, a cross arm 5, a water level monitoring assembly 3, and an adjusting device. One end of the cross arm 5 is fixed to the stand column 1, and the other end is connected to the box body 4. In the embodiment, the cross arm 5 is fixed between the stand column 1 by a clamp, so as to facilitate the disassembly and assembly of the cross arm 5 on the stand column 1, and generally adjust the height between the water level monitoring assembly 3 and the ground with water accumulation hidden dangers. The cross arm 5 and the box body 4 are fixed by welding, so that the box body 4 can be kept stable on the cross arm 5.

[0043] The water level monitoring assembly 3 is arranged below the box body 4, and the adjusting device is arranged in the box body 4, for adjusting the height of the water level monitoring assembly 3, so as to finely adjust the height between the water level monitoring assembly 3 and the ground with water accumulation hidden dangers.

[0044] The adjusting device comprises a rack 7 and a self-locking assembly. The rack 7 is vertically and throughly arranged on the box 4. In this embodiment, a through slot 8 is vertically arranged on the box 4. The rack 7 is slidably arranged on the inner side wall of the through slot 8, and the rack 7 can move up and down relative to the box 4 in the through slot 8. The bottom of the rack 7 is connected with the water level monitoring assembly 3, so as to move synchronously with the water level monitoring assembly 3.

[0045] A limiting slot 10 perpendicular to the rack 7 is horizontally arranged in the box 4. A limiting block 11 is slidably arranged in the limiting slot 10. A connecting block 12 is fixed on one side of the limiting block 11. A second synchronous shaft 29 perpendicular to the limiting slot 10 is horizontally and rotatably arranged on the connecting block 12. A first gear 9 is fixed on one end of the second synchronous shaft 29 and located outside the connecting block 12. Part of the wheel body of the first gear 9 protrudes from the side of the connecting block 12 away from the limiting block 11, so that the rack 7 can be in meshing contact with the first gear 9.

[0046] The first gear 9 can be matched with the rack 7 on one side, and a handle 6 protruding to the outside of the box 4 is fixed on the other side. The handle 6 can drive the first gear 9, the connecting block 12 and the limiting block 11 to move synchronously in the limiting slot 10, and can drive the first gear 9 to rotate synchronously, so that the first gear 9 can drive the rack 7 to move up a certain distance when the first gear 9 is in meshing contact with the rack 7, thereby adjusting the height of the water level monitoring assembly 3 relative to the ground with water accumulation risk.

[0047] The self-locking assembly is used to lock and fix the position of the rack 7 in the box 4 when the first gear 9 is not in contact with the rack 7, so that the vertical position of the water level monitoring assembly 3 after height adjustment remains stable.

[0048] A clamping groove part (not marked) matched with the clamping rod 15 is formed between every two adjacent teeth of the rack 7. The self-locking assembly comprises a swing rod 13 and a first reel 14. One end of the first reel 14 is fixedly arranged on the swing rod 13, and the other end is mounted on the inner side wall of the box 4 through a coil spring (not shown in the figure). The swing rod 13 and the first reel 14 move synchronously.

[0049] In this embodiment, a first rotating hole (not shown in the figure) is arranged on the inner side wall of the box 4, and the other end of the first reel 14 is arranged in the first rotating hole. The coil spring is sleeved outside the first reel 14, and one end is fixedly connected with the inner wall of the first rotating hole, and the other end is fixedly connected with the outer side wall of the first reel 14. When the coil spring does not deform, the clamping rod 15 on the swing rod 13 is clamped in the clamping groove part,

[0050] The one end of the swing lever 13 extends from the bottom of the box 4, which can facilitate the operator to move the swing lever 13 by hand, so as to force the swing lever 13 to drive the clamping rod 15 to disengage from the clamping groove, and to release the locking state of the rack 7 position. During this period, the spring will be elastically deformed, which can help the clamping rod 15 to re-enter the clamping groove between the corresponding two teeth of the rack 7 when the swing lever 13 is not operated by the operator, so as to keep the vertical height position of the water level monitoring assembly 3 stable after height adjustment.

[0051] The other end of the swing lever 13 is fixed with the clamping rod 15, which can be an integral structure between the clamping rod 15 and the swing lever 13, and the connection between the clamping rod 15 and the swing lever 13 is in an inverted L-shaped structure.

[0052] The bottom of each tooth of the rack 7 is a flat surface (not indicated), and when the clamping rod 15 is located in the clamping groove, the bottom plane of the corresponding tooth of the rack 7 will be stably supported on the corresponding rod surface of the free end of the clamping rod 15, so as to prevent the downward movement of the rack 7.

[0053] The top of the rack 7 has a first inclined surface (not indicated) inclined downward from it towards the direction close to the clamping rod 15, and the end surface of the free end of the clamping rod 15 has a second inclined surface (not indicated) in contact and extrusion with the first inclined surface. This makes even if the free end of the clamping rod 15 is clamped in the clamping groove, the first inclined surface of the tooth of the rack 7 located below the free end of the clamping rod 15 will slide in contact and extrusion with the second inclined surface of the clamping rod 15, so that the clamping rod 15 drives the swing lever 13 to move outward, avoiding the interference of the continued upward movement of the rack 7.

[0054] The working mode of the above embodiment is that when the water level monitoring device is installed, the corresponding height between the water level monitoring assembly 3 and the ground with water accumulation risk in the installation area is first judged, the box 4 is installed on the stand column 1 through the cross arm 5, and the adjustment of the distance between the water level monitoring assembly 3 and the ground with water accumulation risk is basically completed. At this time, the water level monitoring assembly 3 is located at the closest position to the ground with water accumulation risk.

[0055] Subsequently, the limiting block 11, the connecting block 12 and the first gear 9 are moved in the limiting groove 10 towards the rack 7 by the handle 6, so that the first gear 9 is in contact with the rack 7. At this time, the handle 6 is pressed down to drive the first gear 9 to rotate, so as to drive the rack 7 to move upwards by a certain distance. During the upward movement of the rack 7, the first inclined surface of the rack 7 tooth located below the free end of the clamping rod 15 is in contact with the second inclined surface of the clamping rod 15, so as to be pressed and matched, so that the free end of the clamping rod 15 is forced to be separated from the clamping groove, thereby avoiding the interference with the upward movement of the rack 7. After the height adjustment of the rack 7 by the rotation of the first gear 9, the clamping rod 15 is reversely rotated under the restoring force of the spring wound on the first spool 14, so that the free end of the clamping rod 15 is clamped into the clamping groove corresponding to the position of the free end of the clamping rod 15 on the rack 7 after the upward movement, thereby automatically locking the position of the rack 7 in the through groove 8, and the height of the water level monitoring assembly 3 after the height adjustment is kept stable. Then, the first gear 9 is pulled back by the handle 6, so that the first gear 9 is separated from the rack 7. The first handle 6 is reversely rotated to the initial position, and the above-mentioned operation of pushing the first gear 9 to engage with the rack 7 is repeated, so that the water level monitoring assembly 3 is gradually increased to the predetermined distance from the ground with hidden water accumulation in a fine adjustment manner.

[0056] If the rack 7 is directly removed, the handle 6 does not need to be operated, and only the end of the swing rod 13 extending out of the bottom of the box body 4 is manually pushed, so that the clamping rod 15 is directly rotated away from the clamping groove, the locking of the rack 7 is released, and then the rack 7 is pulled out of the through groove 8 of the box body 4.

[0057] It is worth mentioning that during the reduction of the upward movement of the rack 7, although the first inclined surface and the second inclined surface are in contact and slidingly pressed, the part of the pressing force will hinder the stability of the upward movement of the rack 7. Therefore, the roller 16 in contact with the groove wall of the limiting groove 10 is installed in the connecting block 12. An open slot (not shown in the figure) is formed in the connecting block 12. The roller 16 is located in the open slot. The roller body of the roller 16 protrudes out of the top slot of the open slot to contact the groove wall of the limiting groove 10. Therefore, when the connecting block 12 drives the roller 16 to move, the roller 16 will rotate in friction with the groove wall of the limiting groove 10.

[0058] The first wire wheel 17 is coaxially fixed on the roller 16, and the second wire wheel 19 is coaxially fixed on the first spool 14. The traction rope (not marked) is wound on the second wire wheel 19, and the free end of the traction rope is connected to the first wire wheel 17.

[0059] The fixed pulley 18 is installed in the box body 4. The fixed pulley 18, the first wire wheel 17 and the second wire wheel 19 form an angle capable of tensioning the traction rope, so that the traction rope is in a tension state between the first wire wheel 17 and the second wire wheel 19, thereby ensuring the effectiveness of the transmission.

[0060] In summary, when the connecting block 12 moves towards the rack 7 with the roller 16, the rotation of the roller 16 drives the first wire wheel 17 to wind the traction rope, the second wire wheel 19 continuously releases the traction rope, and the second wire wheel 19 drives the first spool 14 to rotate, which drives the swing lever 13 to rotate the clamping lever 15 to disengage from the rack 7, directly releasing the locking of the rack 7. The rack 7 is not hindered by the engagement of the first gear 9, and the rack 7 moves smoothly and stably upwards. When the connecting block 12 moves in the opposite direction with the roller 16, the roller 16 drives the first wire wheel 17 to release the traction rope in the opposite direction, and the second wire wheel 19 releases the traction rope released before the first spool 14 rotates reversely under the elastic rotating action of the first spool 14. The reverse rotation of the first spool 14 also drives the swing lever 13 to rotate the clamping lever 15 to approach the rack 7, so that the free end of the clamping lever 15 reenters the corresponding clamping groove part on the rack 7.

[0061] In addition, the second synchronous shaft 29 of the embodiment extends into the open slot at the other end and is coaxially fixed with the second gear 30, the second gear 30 is a ratchet gear, the center of the roller 16 is coaxially inserted and fixed with the first synchronous shaft 20, the first synchronous shaft 20 is rotationally arranged on the inner side wall of the open slot, the first synchronous shaft 20 is sleeved and fixed with the first bevel gear 21, the open slot is provided with a fixed plate 22, the fixed plate 22 is rotationally inserted with a cylinder 23 which is coplanar and perpendicular to the first synchronous shaft 20, one end of the cylinder 23 is fixed with the second bevel gear 24 which is engaged with the first bevel gear 21, the other end of the cylinder 23 is threadedly inserted with a screw rod 25, the outer side of the screw rod 25 is sleeved and fixed with a limiting plate 26, the limiting plate 26 and the fixed plate 22 are connected through the telescopic rod 27, the upper end surface of the free end of the screw rod 25 is provided with a stepped notch slot (not marked), a check lever 28 is rotationally and elastically connected to the slot wall near the one end of the cylinder 23, and the check lever 28 is axially parallel to the axial direction of the screw rod 25 and extends to the outside of the notch slot along the axial direction.

[0062] One end of the check lever 28 located in the notch slot is vertically and horizontally fixedly inserted with the second spool 32, and the side wall of the notch slot is provided with a second rotating hole (not shown in the figure) for the rotation of the second spool 32. The outer side of the second spool 32 is sleeved with a winding spring, one end of the winding spring is fixedly connected with the inner side hole wall of the second rotating hole and the outer side wall of the second spool 32. When the winding spring does not deform, the check lever 28 always remains parallel to the axial direction of the screw rod 25.

[0063] In the embodiment, when the water level monitoring assembly 3 is not adjusted, the free end of the handle 6 is located at the upper position, at this time the check lever 28 is located between the teeth of the second gear 30. Due to the tooth body characteristics of the ratchet, the clockwise rotation of the second gear 30 is prevented by the intervention of the check lever 28, so that the position of the free end of the handle 6 remains stable, avoiding the up and down shaking of the handle 6 when not in use, causing damage.

[0064] When the connecting block 12 is moved to the through slot 8 by the handle 6 to achieve the meshing of the first gear 9 and the rack 7, the roller 16 drives the first synchronous shaft 20, the first bevel gear 21, the second bevel gear 24, and the cylinder 23 to rotate synchronously, so that the cylinder 23 and the screw 25 are in threaded action with each other, and the screw 25 is driven by the cylinder 23 to move only in the axial direction under the limiting action of the limiting plate 26 and the fixed plate 22 and the limiting action of the telescopic rod 27, so that the screw 25 is retracted into the cylinder 23, the check rod 28 is driven to move away from the teeth of the second gear 30, the check rod 28 is prevented from interfering with the rotation of the second gear 30, and the interference with the rotation of the handle 6 is avoided.

[0065] When the handle 6 is pulled back to the initial position by the handle 6 located below each time the first gear 9 rotates, the check rod 28 gradually returns to the initial position (i.e., is again clamped between the corresponding teeth of the second gear 30), and the free end of the handle 6 is moved back to the upper position in the reverse direction to facilitate the meshing action of the first gear 9 on the rack 7. During the movement of the free end of the handle 6 back to the upper position, the handle 6 drives the first gear 9, the second synchronous shaft 29, and the second gear 30 to rotate in the reverse direction synchronously, and according to the characteristics of the ratchet, the teeth of the second gear 30 slide and press the check rod 28 from bottom to top, driving the check rod 28 to move and rotate upward, providing a corresponding space gap for the teeth of the second gear 30 during the rotation of the second gear 30. When the free end of the handle 6 is returned to the upper position of the box 4, the handle 6 is stopped, at which time the check rod 28 is returned to the horizontal state under the action of the elastic force of the second reel 32 and the coil spring, and the support force provided by the bottom groove wall of the notch groove, and interferes with the teeth of the second gear 30 located directly above the rod surface, preventing the second gear 30 from rotating clockwise, and cooperating with the shape of the outer wall of the box 4 to prevent the handle 6 from being moved from the upper position to the lower position, so that the free end of the handle 6 always remains in a stable state above the box 4 when not in use, to ensure the effectiveness of the next time the handle 6 is moved and rotated to adjust the water level monitoring assembly 3.

[0066] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art based on the present application are within the scope of the present application.
