DETAILED DESCRIPTION

[0025] 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.

[0026] When implementing: Figure 1-4 As shown, a water level detection device for water conservancy design includes: a pile foundation 1, a cover 3 is fixedly connected to the top of the pile foundation 1, through holes are evenly opened on the outer bottom of the outer cover, and the through holes penetrate to the inner side of the outer cover 3, and a cutting mechanism 5 is arranged on the surface of the outer cover 3;

[0027] The cutting mechanism 5 includes a power structure and a cutting component arranged on the surface of the outer cover 3. The power structure includes a gear ring 51. The surface of the gear ring 51 is meshedly connected with a gear 573. The top of the gear 573 is fixedly connected with a servo motor 574.

[0028] The cutting component includes a connecting rod, a connecting ring 53, a fixing rod 54 and a cutting knife 55;

[0029] The bottom end of the gear ring 51 is fixedly connected to a connecting ring 53 through a plurality of connecting rods. The bottom end of the connecting ring 53 is evenly connected to a plurality of vertical fixing rods 54 along the circumferential direction. The surface of the fixing rod 54 is evenly connected to a plurality of cutting knives 55 along the vertical direction to cut the waterweed.

[0030] In addition, a vertical push plate 56 is provided between any two adjacent fixing rods 54 , and all the push plates 56 are evenly arranged at the bottom of the connecting ring 53 so as to push the cut waterweed out and away from the outer cover 3 .

[0031] A vertical rod 2 is installed at the top of the pile foundation 1, and the vertical rod is located at the center of the outer cover; a water level sensor body 4 is installed on the vertical rod 2; the water level sensor body 4 is a type of pressure-type water level sensor. When the water in the river channel enters the outer cover 3 and the surface of the water level sensor body 4 through the through hole on the outer cover 3, the water level sensor body 4 determines the height of the water by measuring the pressure exerted by the water on the bottom of the sensor, thereby detecting the height of the water level in the river channel.

[0032] When it is necessary to cut the aquatic plants on the outer cover 3, the gear ring 51 is driven to rotate, and the gear ring 51 rotates and drives the connecting ring 53 to rotate, thereby driving the fixing rod 54, the cutting knife 55 and the pushing plate 56 to move, the moving cutting knife 55 cuts the aquatic plants, and the moving pushing plate 56 pushes the cut aquatic plants away from the outer cover 3, and the water in the river channel flows to the water level sensor body 4 on the inner side of the outer cover 3, and the water level sensor body 4 detects the height of the water in the river channel.

[0033] like Figure 3 As shown, in order to prevent aquatic plants from entering the interior of the outer cover through the through hole, a water frame 52 for storing water is fixed between the gear ring 51 and the connecting ring 53; the bottom end of the water frame 52 is connected to a cleaning assembly 57; the cleaning assembly 57 includes a number of nozzles 571 equal to that of the push plate 56, and the nozzles are arranged on the side of the push plate 56 facing away from the cutting knife 55; specifically, the top of the nozzle extends to the inner wall of the water frame 52 to obtain spray water, and a plurality of nozzles 572 are arranged at the lower half of the nozzle; preferably, a through cavity for accommodating the nozzle is provided on the push plate, so as to facilitate the spray water in the nozzle 572 to flush the aquatic plants at the position of the cutting knife 55.

[0034] Preferably, the surface of the nozzle 572 is trumpet-shaped.

[0035] like Figure 2 As shown, a filter screen 5710 is fixedly connected to the inner wall of the nozzle 572. The filter screen 5710 is used to block the water plants and prevent the water plants from flowing into the nozzle 572.

[0036] Preferably, the inner wall of the water frame 52 is provided with a driven ring 577, the inner side of the driven ring 577 is connected to a water pump 575 provided on the outer side of the water frame 52, and the water pump 575 is connected to a filter cartridge through a filter suction pipe 576. The filter cartridge is used to prevent aquatic plants from entering the water pump 575 through the water pipe, thereby reducing the probability of the water pump 575 being blocked.

[0037] The water pump 575 draws water from the river channel through the filter straw 576 and transports it to the nozzle 571 through the water frame 52. The water in the nozzle 571 is flushed onto the cutting knife 55 and the cut water plants through the nozzle 572, thereby allowing the cut water plants to quickly move away from the outer cover 3.

[0038] like Figure 3 As shown, since the gear ring 51 and the connecting ring 53 drive the water frame 52 to rotate, the inner wall of the water frame 52 is fixedly connected with a first sealing bearing 579, the top of the water frame 52 is fixedly connected with a second sealing bearing 578, the inner edge of the first sealing bearing 579 is fixedly connected to the outer surface of the driven ring 577, and the outer edge of the second sealing bearing 578 is fixedly connected to the inner wall of the driven ring 577. The rotation of the water frame 52 drives the first sealing bearing 579 and the second sealing bearing 578 to rotate, and under the action of the first sealing bearing 579 and the second sealing bearing 578, the driven ring 577 will not rotate with the water frame 52.

[0039] like Figure 4 As shown, the surface of the outer cover 3 is fixedly connected to a support frame 5711, the surfaces of the gear ring 51 and the gear 573 are both rotatably connected to the inner wall of the support frame 5711, the surface of the servo motor 574 is fixedly connected to the inner wall of the support frame 5711, and the surface of the water pump 575 is fixedly connected to the surface of the support frame 5711. The support frame 5711 is used to support and protect the gear ring 51, the gear 573 and the servo motor 574.

[0040] It should be noted that the water level sensor body 4, water pump 575, servo motor 574, etc. in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the water level sensor body 4, water pump 575, and servo motor 574 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0041] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
