A device for displaying the depth of a body of water

Abstract

The invention discloses a device for displaying the depth of water. The device comprises a vertical rod, a floating box and a transmission device. An upper placement rod and a lower placement rod are slidingly connected with each other to form the vertical rod. The vertical rod is telescopic. The floating box is slidingly connected to the vertical rod. The transmission device can transmit the floating box motion to the upper placement rod. The device also comprises a hole and a channel. The hole is arranged at the bottom of water. The channel is vertical. The upper end of the channel is located to the bottom of the hole. The hole can contain the floating box. The vertical rod is inserted into the channel. A distance between the waterline and the bottom of water is equal to a distance between the upper end of the upper placement rod and the waterline of the floating box. The device can visually display water depth and has a wide application range.

Description

technical field [0001] The solution of the 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 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 ...

[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

But in actual use, this technical solution also has deficiencies, specifically as follows: the range of application of this device is limited, as the length of the upper pole is 2 meters, the length of the lower pole is 2 meters, and the upper pole is fully retracted To the lower pole, the length of the pole is 2 meters, that is to say, the length of the pole cannot be less than 2 meters. Obviously, when the depth of the water body is less than 1 meter, the length of the pole is always kept at 2 meters. The length of the display device does not change with the depth of the water body, that is, when the depth of the water body is less than 1 meter, this display device loses its effect. Obviously, the application range of this display device does not include water bodies with a depth of less than 1 meter. In view of this , it is necessary to improve this display device so that it has a wide range of applications
