Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example, refer to Figures 1-9A water level real-time monitoring structure for a water conservancy project includes a main support 1, a camera 2 fixedly connected to the main support 1, a support rod 3 fixedly connected to the top of the main support 1, an outer cover 4 fixedly connected to the support rod 3, a controller installed inside the outer cover 4, a long rod 5 installed below the outer cover 4, a float 7 fixedly connected to the bottom of the long rod 5, the top of the float 7 being conical, a motor 8 fixedly connected to the top of the support rod 3, a rotating rod 11 fixedly connected to the output shaft of the motor 8, the rotating rod 11 being slidably sleeved on the inner side wall of the long rod 5, the outer side wall of the long rod 5 being provided with external threads, a sleeve 12 being connected to the long rod 5 via threaded engagement, the inner side wall of the sleeve 12 being slidably disposed with the inner side wall of the long rod 5, a fixed tube 13 being slidably sleeved on the outer side wall of the sleeve 12, the long rod 5 being hollow, a bent part 6 being provided on the long rod 5, a set of sliding rods 15 being fixedly connected to the outer side wall of the rotating rod 11, the sliding rods 15 being embedded in the inner side wall of the long rod 5 and slidably disposed with the long rod 5.

[0028] A first resistor rod 21 and a second resistor rod 22 are fitted into the outer wall of the sleeve 12. An insulating sheet 23 is provided between the first resistor rod 21 and the second resistor rod 22. The first resistor rod 21 and the second resistor rod 22 are insulated from the sleeve 12. A contact rod 24 is fixedly connected to the inner wall of the fixed tube 13. A spring is provided on the contact rod 24. The end of the contact rod 24 is hemispherical. The hemispherical end of the contact rod 24 is in sliding contact with the first resistor rod 21 and the second resistor rod 22. The hemispherical end of the contact rod 24 is electrically connected to the controller. The top and bottom ends of the first resistor rod 21 and the second resistor rod 22 are provided with contacts. The first resistor rod 21 and the second resistor rod 22 are electrically connected to the controller through the contacts. The controller integrates a signal conversion module.

[0029] A guide rod 31 is fixedly connected to the outer wall of the sleeve 12. Multiple bosses 32 are fixedly connected to the guide rod 31. The bosses 32 are equidistantly distributed on both sides of the guide rod 31. A slide is provided on the inner wall of the fixed tube 13. Multiple locking platforms 33 are provided on the slide. The multiple locking platforms 33 are equidistantly distributed on both sides of the slide. A baffle 34 is slidably arranged between two adjacent locking platforms 33. The baffles 34 are spaced apart on the fixed tube 13. A return spring 35 is fixedly connected between the baffle 34 and the side wall of the slide.

[0030] It should be noted that: by setting the bending part 6, when the long rod 5 rotates, it drives the float 7 to make a circular motion instead of rotating itself; the top of the float 7 is set in a cone shape, and when aquatic plants are wrapped around the float 7, they are easy to fall off because there is no suspension point; by setting the sliding rod 15 on the rotating rod 11, the rotating rod 11 can only slide up and down with the long rod 5, rather than rotate relative to it; since the sleeve 12 and the fixed tube 13 are in a sliding relationship, the sleeve is not constrained by the fixed tube 13 when it moves up and down.

[0031] The working principle of this water level real-time monitoring structure for water conservancy projects is as follows: The structure is fixed to the waterside to be monitored by the main support 1, and the float 7 is placed on the water. At this time, the float 7 is suspended on the water surface. The positions of the contact rod 24 and the insulating sheet 23 are relatively corresponding. The water level is determined by detecting the resistance between the contact rod 24 and the top of the first resistance rod 21. Specifically, when the water level drops, the float 7 moves downward, driving the long rod 5. The long rod 5 drives the sleeve 12 downward through the thread, shortening the distance between the top of the contact rod 24 and the first resistance rod 21, thus reducing the resistance between the contact rod 24 and the first resistance rod 21 (the resistance at both ends of the first resistance rod 21 is the largest). The signal conversion module in the controller converts the resistance signal difference into an electrical signal and transmits it to the external control console. The smaller the resistance value, the deeper the water level drops. The degree of water level drop is determined by judging the resistance value. The detection method for water level rise is the same as that for water level fall. The smaller the resistance transmitted by the second resistance rod 22, the higher the water level rises. The water level height is detected in real time based on this principle.

[0032] When staff observe foreign objects entangled on float 7 via camera 2 from the external control console, they control motor 8 to rotate. Motor 8 drives rotating rod 11 to rotate, which in turn drives long rod 5 to rotate via sliding rod 15, causing float 7 to move in a circular motion. This circular motion of float 7 is more effective than simply rotating. When long rod 5 rotates, the friction between it and the threaded sleeve 12 causes it to rotate as well. Since sleeve 12 has a guide rod 31 located in the slide of fixed tube 13, the friction between the threads drives guide rod 31 to drive boss 32 in a circular motion. This causes boss 32 to push baffle 34 against the spring force of return spring 35 and move towards locking platform 33. Once boss 32 and locking platform 33 are engaged, the vertical movement of guide rod 31 is restricted, limiting its position. The rotation between the threads drives long rod 5 to move vertically, which in turn drives float 7 to move vertically, helping float 7 to escape entanglement.

[0033] The controller controls the motor 8 to rotate in the opposite direction by the same number of revolutions, causing the other side boss 32 to engage with the mounting plate 33. The long rod 5 and the sleeve 12 return to their initial positions, and the float 7 returns to the surface position. Since the guide rod 31 is no longer subjected to rotational force, under the restoring force of the return spring 35, the guide rod 31 is pushed back into the slide of the fixed tube 13 by the boss 32, so that the sleeve 12 returns to the state where it can slide up and down in the fixed tube 13, thus completing the work of cleaning debris from the float 7.

[0034] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
