[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 3 In the embodiment of the utility model, a water level and flow rate monitoring device of a hydraulic power plant comprises a positioning rod 1, a fixing rod 2 is fixed to the outer wall of the positioning rod 1, one end of the fixing rod 2 is connected to a detection rod 3 for detecting the flow rate of water flow through a movable rod 401, and an adjustment mechanism 4 is arranged on the fixing rod 2;

[0030] The adjustment mechanism 4 includes a reset unit and a limit unit;

[0031] The limiting unit is used to limit the movement of the detection rod 3;

[0032] The reset unit is used to always give the limit unit an elastic force in one direction;

[0033] The limiting unit includes a movable rod 401, a limiting groove 402, a connecting seat 403, a stop rod 404, and a pressing block 405;

[0034] The movable rod 401 is sleeved on the inner wall of the fixed rod 2 and extends to the outside of the fixed rod 2. The movable rod 401 is used to drive the detection rod 3 to move;

[0035] The limiting groove 402 is formed on the outer wall of the movable rod 401, and the limiting groove 402 cooperates with the stop rod 404 to limit the movement of the movable rod 401;

[0036] The connecting seat 403 is fixed to the outer wall of the fixing rod 2, and the connecting seat 403 is used to provide support for the rotation of the supporting rod 404;

[0037] The stopper rod 404 is rotatably connected to the inner cavity of the connecting seat 403 and extends to the inner side of the limiting groove 402. The stopper rod 404 is used to provide a direction of obstruction to the movement of the movable rod 401.

[0038] The pressing block 405 is fixed to the outer wall of the push rod 404, and the pressing block 405 is used to drive the push rod 404 to rotate;

[0039] The reset unit includes a guide rod 406 and a spring 407;

[0040] The guide rod 406 is fixed to the outer wall of the fixing rod 2 and passes through the pressing block 405. The guide rod 406 is used to provide a guide for the rotation of the pressing block 405.

[0041] The two ends of the spring 407 are respectively clamped on the outer wall of the fixing rod 2 and the outer wall of the pressing block 405, and the spring 407 is used to always give the pressing block 405 an elastic force to rotate outward;

[0042] A sensor for detecting the water level is arranged above the positioning rod 1 , and an impeller for detecting the flow velocity is installed at the bottom end of the detection rod 3 .

[0043] In this embodiment: when this device is used, when the position of the detection rod 3 needs to be lengthened, the movable rod 401 can be directly pulled outward. The movement of the movable rod 401 will synchronously drive the limit slot 402 and the detection rod 3 to move. The limit slot 402 contacts the end of the push rod 404 during the movement. Since the outer wall of the push rod 404 is tilted as a whole, the limit slot 402 will continue to give thrust to the push rod 404, thereby driving the pressing block 405 to move back and forth along the outer wall of the guide rod 406 and giving the spring 407 an extrusion force until the detection rod 3 moves to the required position. At this time, the push rod 404 will also be aligned with the inner side of a limit slot 402, limiting the reset of the limit slot 402, thereby achieving the purpose of quickly unfolding and pulling out the detection rod 3, and further improving work efficiency.

[0044] Please refer to Figure 1-Figure 3 The push rod 404 and the pressing block 405 are in an inclined state as a whole. One end of the push rod 404 is located on the inner side of a limiting groove 402. There are multiple limiting grooves 402, and the multiple limiting grooves 402 are evenly distributed on the outer wall of the movable rod 401. The movable rod 401 will not be limited by the push rod 404 when it moves out of the fixed rod 2.

[0045] In this embodiment: through this structure, when the detection rod 3 needs to be stored, a pressing force can be applied to the pressing block 405, so that the pressing block 405 drives the supporting rod 404 to rotate and move out of the inner side of the limiting groove 402, thereby releasing the movement limit of the movable rod 401. At this time, a thrust can be applied to the movable rod 401 to make it enter the interior of the fixed rod 2, thereby completing the storage of the movable rod 401.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
