Device for displaying water body depth

Abstract

The invention relates to a device for displaying the water body depth. According to the technical scheme, the device comprises a stand rod, a floating box and a transmission device. The stand rod is formed by connecting an upper placing rod with a lower placing rod in a sliding mode and is stretchable; the floating box is connected to the lower placing rod in a sliding mode; the transmission device is used for transmitting the motion of the floating box to the upper placing rod. In particular, when the floating box ascends, the upper placing rod is driven to ascend, the ascending distance of the upper placing rod is two times that of the floating box; when the floating box descends, the upper placing rod is driven to descend, the descending distance of the upper placing rod is two times that of the floating box; when the stand rod is vertically placed, a waterline of the floating box serves as a boundary, and the length of the part, located above the waterline, of the stand rod is equal to the length of the part, located below the waterline, of the stand rod. The device has the advantages of being simple and reasonable in structure, and capable of conveniently, rapidly and visibly displaying the water body depth.

Description

technical field [0001] The solution of the present invention relates to a device for displaying the depth of a water body. Background technique [0002] In real life, when people need to know the depth of the water body, they often insert a long ruler in the water body, and according to the scale formed by the water surface on the long ruler, the depth of the water body is worth the value. However, this conventional technique has some disadvantages: 1. The operator needs to get close to the long ruler and carefully observe the scale value. This process is not convenient and fast; 2. After the operator obtains the scale value of the water depth, he has to make corresponding associations to obtain the corresponding length of the scale value. For a specific image, if the scale value of the depth of the water body is 1.2 meters read from a long ruler, the operator must first imagine a specific image with a length of 1 meter, and then obtain a specific image with a length of 1.2 ...

[0002] In real life, when people need to know the depth of a water body, they often insert a long ruler in the water body, and obtain the depth of the water body according to the scale formed by the water surface on the long ruler. However, this conventional technique has some disadvantages: 1. The operator needs to get close to the long ruler and carefully observe the scale value. This process is not convenient and fast; second, after the operator obtains the scale value of the depth of the water body, he has to make corresponding associations to obtain the length corresponding to the scale value. For a specific image, if the scale value of the water depth is 1.2 meters read from a long ruler, the operator must first imagine a specific image with a length of 1 meter, and then obtain a specific image with a length of 1.2 meters. It can be seen that this process is not intuitive enough ; These shortcomings appear to be particularly prominent in some cases, for example, when there is a heavy rain, a large amount of water accumulates in the culverts of urban roads, and a scale that shows the water level is preset on the general culvert walls. , which is neither convenient nor intuitive, will put itself in a very dangerous situation
