Description

A device for dynamically measuring water level

technical field

The utility model belongs to the field of water level measurement, in particular to a device for dynamically measuring water level.

Background technique

In hydraulic and hydraulic model tests, due to actual engineering needs, it is often necessary to measure the water level during the test. During the test, due to the fluctuation of the flow rate and the fluctuation of the water level, there are certain errors in the measurement and reading of the water level. Without accurate instruments, the surveyors often measure the water level with a simple water gauge and simply observe the water body. It is read at the change of the water gauge, but the fluctuation of the water level changes quickly, which is easy to cause fatigue under long-term observation; and in the measurement process, in order to reduce the error caused by man, different locations in the entire test watershed or test river channel The water level measurement needs to be measured by fixed personnel from beginning to end, which undoubtedly increases the measurement time, and the accuracy of the test results is also reduced under long-term work intensity. Therefore, in order to reduce the measurement time and improve the measurement efficiency, under the premise of ensuring the accuracy, a measurement device suitable for the measurement personnel to intuitively read the water level change is needed.

Beneficial effect

The utility model adopts the method of automatically adjusting and displaying the water level by using hydraulic power, changes the floating arm according to the floating and sinking of the floating ball, and then intuitively displays the water level change and the change size through the direction of the measuring needle on the water level scale. When the water level rises, the floating ball also rises with the water level under the action of buoyancy; when the water level drops, the floating ball drives the pointer down as the water body drops, and the measuring observer can directly read the change and size of the water level through the change of the pointer .

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figures 1-3, the utility model provides a dynamic water level measurement device, including a water level probe 1, a water level scale 2, a probe slideway 3, a floating arm 4 and a floating ball 5; With water depth, the stylus slideway 3 is installed longitudinally on the central axis of the water level scale gauge 2, and the water level probe 1 is installed on the stylus slideway 3, and can slide up and down along the stylus track 3, used to adjust the water level For measurement; the up and down sliding installation mentioned here means that the water level probe 1 is sleeved on the outer periphery of the probe track 3 or the water level probe is embedded in the probe track 3; when the water level probe 1 slides up and down along the probe track 3, The pointer of the water level probe 1 can point to the water level scale gauge 2 to display the measured water level; here the probe slideway 3 is rigidly connected with the water level scale gauge 2; the floating arm 4 is made of a material with a density lower than that of water. It is rigidly connected with the water level probe 1, and the other end is connected with the floating ball 5; the floating ball 5 adopts a PP hollow floating ball with a small specific gravity, which has a small specific gravity and a stable center of gravity. As the water level fluctuates up and down, it drives the floating arm 4 to change, and the floating arm 4 and then affect the water level probe 1 to point to different readings on the water level scale gauge 2. Change the position of the floating arm 4 according to the rising and sinking of the water level float 5 so as to display the water level change on the water level scale 2 . That is, when the water level rises, the floating ball 5 also rises with the water level under the action of buoyancy, pulling the water level probe 1 to move upward; The measurement observer can directly read the change of the water level through the change of the degree of the water level probe 1 pointing to the water level scale gauge 2 . This device can adjust the dial according to the range of the specific water level, and can be installed on the side of the test wall groove to relieve the trouble of manual operation and measurement. It can be widely used in hydraulic tests, and truly realizes the purpose of dynamic and intuitive measurement of water level changes.

In addition, the floating arm 4 and the floating ball 5 can be installed only on one side of the stylus track 3 or symmetrically installed on both sides of the stylus track 3 .

The above is only the embodiment of the utility model, and its description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the utility model. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
