[0036] Combine the following Figure 1 The embodiment shown in Figure 5 describes the technical solution of the utility model: wherein, as Figures 1 to 4 As shown:

[0037] A trapezoidal channel water level measuring device, comprising: a first telescopic rod 1, a second telescopic rod 2 and a third telescopic rod 3, wherein the first telescopic rod 1, the second telescopic rod 2 and the third telescopic rod 3 are connected end to end to form a triangular structure;

[0038] The first telescopic rod 1 and the second telescopic rod 2 form two adjacent sides of a triangle and are hinged; both ends of the third telescopic rod 3 are hinged to the first telescopic rod 1 and the second telescopic rod 2 respectively;

[0039] It also includes a water level measuring sensor 4, a first driving mechanism 5, a second driving mechanism 6 and a controller. The detection needle of the water level measuring sensor 4 is arranged along the axial direction of the second telescopic rod 2; the first driving mechanism 5 is used to drive the first telescopic rod 1 to extend and retract, and the second driving mechanism 6 is used to drive the second telescopic rod 2 to extend and retract; the controller is also electrically connected to the first driving mechanism 5 and the second driving mechanism 6.

[0040] The utility model provides a trapezoidal channel water level measuring device, which is provided with a first telescopic rod 1, a second telescopic rod 2 and a third telescopic rod 3, and the first telescopic rod 1, the second telescopic rod 2 and the third telescopic rod 3 are connected end to end to form a triangular structure, so that the inclination of the third telescopic rod 3 can be made consistent with the inclination of the inclined surface of the trapezoidal channel by changing the length of the first telescopic rod 1 and the second telescopic rod 2, and at the same time, the second telescopic rod 2, that is, the measuring rod, can be in a vertical direction. In this way, the operator only needs to stand on the dam to accurately measure the water level depth.

[0041] According to the trapezoidal channel water level measuring device provided by the embodiment of the utility model, Figure 3 As shown, the first driving mechanism 5 includes: a first threaded rod 501 and a first motor 502. The first threaded rod 501 is arranged along the axial direction of the first telescopic rod 1, and penetrates the first movable rod 101 of the first telescopic rod 1 and is rotatably connected with the first fixed rod 102 of the first telescopic rod 1; the first motor 502 is arranged in the inner cavity of the first fixed rod 102 and is connected to the first threaded rod 501, and is used to drive the first threaded rod 501 to rotate; the first movable rod 101 is threadedly connected to the first threaded rod 501.

[0042] In some embodiments, the first movable rod 101 is provided with an internal threaded hole and can be threadedly connected to the first threaded rod 501. When the first motor 502 rotates, the first movable rod 101 can slide axially; of course, the second driving mechanism 6 also needs to follow the extension and retraction, and the speed adjustment is specifically completed by the controller, thereby realizing the adjustment of the inclination of the third telescopic rod 3 and the adjustment of the length of the measuring rod (second telescopic rod 2).

[0043] According to the trapezoidal channel water level measuring device provided by the embodiment of the utility model, Figure 4 As shown, the second driving mechanism 6 includes: a second threaded rod 601 and a second motor 602. The second threaded rod 601 is arranged along the axial direction of the second telescopic rod 2, and penetrates the second fixed rod 201 of the second telescopic rod 2 and is rotatably connected with the second movable rod 202 of the second telescopic rod 2; the second motor 602 is arranged in the inner cavity of the second movable rod 202 and is connected to the second threaded rod 601, and is used to drive the second threaded rod 601 to rotate; the second fixed rod 201 is threadedly connected to the second threaded rod 601.

[0044] In some embodiments, a threaded hole is provided in the inner cavity of the second fixed rod 201, which can be threadedly connected to the second threaded rod 601. When the second threaded rod 601 rotates driven by the second motor 602, the second movable rod 202 can move up and down as a whole; so as to meet the adjustment of the inclination of the third telescopic rod 3 and the adjustment of the measurement depth at the same time.

[0045] like Figure 5As shown, the third telescopic rod 3 must always have the same slope as the inclined plane of the trapezoidal channel, that is, they are parallel to each other. During use, the third telescopic rod 3 can be fitted with the inclined plane, while ensuring that the second telescopic rod 2 is perpendicular to the water surface. In this way, the operator can measure the water level depth when standing on the dam. If a dam with a different slope is encountered, it can be adjusted on the controller. The controller can control the different speeds of the first motor 502 and the second motor 602 to achieve the adjustment of the slope.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
