Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level gauges, in particular to an intelligent photoelectric two-color liquid level gauge panel. Background Art

[0002] Photoelectric two-color liquid level meter is an instrument that detects the level of the measured liquid through the red and green changes of the LED light column. It has the advantages of high display brightness, long visual distance, clear scale, large display angle, more serialized products, intelligent, corrosion-proof and explosion-proof, high temperature and high pressure resistance, high sealing, leakage prevention, no blind spots, eye-catching display, intuitive reading, etc. Therefore, it is widely used in the production process of various industries such as electricity, metallurgy, petroleum, chemical industry, environmental protection, shipbuilding, and construction. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with publication number CN201926488U discloses a photoelectric liquid level meter. The measuring tube is connected to the measured container through a flange. There is a float in the measuring tube, a magnetic steel is installed in the float, and a liquid level display panel is installed on the outside of the measuring tube. The display panel includes a two-color plane light-emitting tube, a magnetic sensitive element and an auxiliary control element welded on a circuit board. The display panel is installed in an aluminum alloy frame and then fixed on the measuring tube. The distance between adjacent two-color plane light-emitting tubes represents a unit length. The photoelectric liquid level meter emits light through the light-emitting tube, which is convenient for the staff to quickly see the junction of the two colors. The liquid level display is clear at a glance, but in actual use, the staff often needs to read the specific height of the liquid level through the liquid level display panel on one side of the light-emitting tube. Although the light-emitting tube has no display blind area, the plate-shaped liquid level display panel often has a display blind area, which is not convenient for the staff to read the specific liquid level height;

[0004] 2. When installing the photoelectric two-color liquid level meter, the display panel needs to be installed on the outside of the light-emitting tube to facilitate the staff to read the data. To ensure the convenience of data reading, the light-emitting tube needs to be exposed to the environment over a large area, resulting in a small contact area between the display panel and the light-emitting tube, and reduced connection stability. When the light-emitting tube is subjected to external force, the liquid level meter has no protective structure to protect it, causing the light-emitting tube to be easily damaged, affecting the normal use of the liquid level meter. Utility Model Content

The staff can slide multiple display panels to appropriate positions according to usage habits, which is convenient for the staff to read the liquid level height through the display panel and the light-emitting tube at different positions, thereby improving the convenience of use. The light-emitting tube can be positioned by the first positioning airbag and the second positioning airbag, thereby improving the convenience of installation and the stability of the connection between the light-emitting tube and the panel. The light-emitting tube can be shock-absorbing and protected by the first positioning airbag and the second positioning airbag, thereby further reducing the probability of damage to the light-emitting tube.

[0009] Furthermore, a mounting plate is welded and fixed to the bottom of the outer peripheral surface of the connecting base, a connecting frame is welded and fixed to the connecting base and the top of each supporting frame, the connecting frame of the connecting base is clamped and fixed to the bottom of the adjacent supporting frame, the connecting frames of the plurality of supporting frames are clamped and fixed to the bottom of the adjacent supporting frames, the top of the connecting frame of one of the supporting frames is clamped and fixed to a limiting plate, and the limiting plate is located at the top of the plurality of supporting frames;

[0010] When installing the light-emitting tube of the photoelectric two-color liquid level meter, the light-emitting tube is passed through the limit plate, the connection base and multiple support frames. The support frame can support and initially protect the outer side of the light-emitting tube of the photoelectric two-color liquid level meter, thereby reducing the probability of damage to the light-emitting tube.

[0011] Furthermore, a through hole is formed through the top of each connecting frame, the through hole is located inside the supporting frame, and a sliding groove is formed on the outer peripheral surface of each supporting frame;

[0012] The connecting frame can provide a large gap between multiple support frames, so that the staff can read the color change of the light-emitting tube through the gap between two adjacent support frames without affecting the normal use of the photoelectric two-color liquid level meter.

At the same time, the first positioning airbag and the second positioning airbag can provide shock-absorbing protection for the light-emitting tube, thereby further reducing the probability of damage to the light-emitting tube.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model solves the problem that the photoelectric liquid level meter emits light through the light-emitting tube by setting a connecting base and a display panel, so that the staff can quickly see the junction of the two colors and the liquid level display is clear at a glance. However, in actual use, the staff often needs to read the specific height of the liquid level through the liquid level display panel on one side of the light-emitting tube. Although the light-emitting tube has no display blind area, the plate-shaped liquid level display panel often has a display blind area, which is not convenient for the staff to read the specific liquid level height. After the light-emitting tube of the photoelectric two-color liquid level meter is installed on the connecting base, the support frame and the inner side of the limit plate, the staff can slide multiple display panels along the slide groove to multiple suitable angles according to the usage habits, which is convenient for the staff to quickly read the liquid level height at multiple positions, greatly improving the convenience of use.

The utility model solves the problem that, when installing the photoelectric two-color liquid level meter, the display panel needs to be installed on the outside of the light-emitting tube so that the staff can read the data. To ensure the convenience of data reading, the light-emitting tube needs to be exposed to the environment over a large area, resulting in a small contact area between the display panel and the light-emitting tube, and reduced connection stability. When the light-emitting tube is subjected to external force, the liquid level meter has no protective structure to protect it, resulting in the light-emitting tube being easily damaged, affecting the normal use of the liquid level meter. After the light-emitting tube of the photoelectric two-color liquid level meter is plugged into the connecting base, the support frame and the inner side of the limit plate, the air pump is controlled to pump air into the first positioning airbag and the second positioning airbag, so that the first positioning airbag and the second positioning airbag are expanded and squeezed on the outer peripheral surface of the light-emitting tube. The multiple second positioning airbags can position the light-emitting tube over a large area, thereby improving the stability of the positioning connection. At the same time, the light-emitting tube can be shock-absorbingly protected by the first positioning airbag and the second positioning airbag, thereby further reducing the probability of damage to the light-emitting tube.
