Problems solved by technology

However, it is difficult to read the scale in low light
For example, when construction machinery such as coal shearers are working underground in a dark working environment, due to the small underground space and inconvenient activities for construction personnel, it is more difficult to read the scale through the existing liquid level gauge
In addition, if only the approximate height of the liquid in the container is observed, the liquid cannot be visually observed due to the relatively dark construction environment.

Embodiment Construction

[0022] Below will combine the preferred embodiment of the present invention figure 1 and figure 2 , clearly and completely describe the technical solutions in the embodiments of the present invention.

[0023] see figure 1 , the present invention provides a liquid level display device 1, which is applied to a container 2 to roughly measure the liquid level of the liquid 3 in the container 2.

[0024] The liquid level display device 1 of the first preferred embodiment of the present invention includes a tube body 11 , a photosensitive element 12 and a connecting element 13 .

[0025] The tube body 11 is roughly in the shape of a hollow tube, which is made of transparent materials, such as glass, plexiglass and the like. The tube body 11 is used to contain the liquid 3 in the container 2 and the photosensitive element 12 . The inside of the tube body 11 is provided with a cavity for accommodating the liquid, and two through holes (not shown in the figure) are respectively o...

Abstract

The invention discloses a liquid level display device, which is used for measuring the liquid level of liquid in a container. The liquid level display device comprises a non-light tight tube body, a photosensitive element and two connecting elements. A cavity for accommodating the liquid is formed inside the non-light tight tube body. The photosensitive element is accommodated in the cavity or arranged between the tube body and the container. The two connecting elements are connected with the tube body and used for fixing the tube body on the container. Each connecting element is provided with a channel for communicating the cavity and the container. One connecting element is arranged at the lower end of the tube body, and the channel of the connecting element can be provided for liquid to be measured to pass through. The other connecting element is arranged at the upper end of the tube body. The liquid level display device is provided with the photosensitive element, so an operator can judge the liquid level of the liquid in the container by viewing the position of the photosensitive element or according to the length of a relatively darker part on the photosensitive element in a relatively darker or lightless environment.

Description

technical field [0001] The invention relates to a liquid level display device, a container using the liquid level display device and construction machinery. Background technique [0002] The existing liquid level gauge has a fixed scale, which is fixed on the container, and the height of the liquid level in the container can be obtained by reading the scale corresponding to the liquid level of the liquid in the container. However, it is difficult to read the scale in low light. For example, when construction machinery such as coal shearers are operating underground in a dark working environment, due to the small underground space and inconvenient activities for construction personnel, it is more difficult to read the scale through the existing liquid level gauge. In addition, if only the approximate height of the liquid in the container is observed, the liquid cannot be visually observed due to the relatively dark construction environment. [0003] Therefore, it is an urge...
