After long-term wind erosion, sun exposure and rain, the paint markings become blurred and the liquid level of the water tank cannot be accurately identified, especially at night, even with a flashlight at close range, the liquid level cannot be seen clearly. In addition, there are many water tanks on site and the tanks are relatively scattered and far apart, so personnel must be at close range to see the liquid level clearly, and each inspection takes a long time.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0015] The utility model relates to an on-site liquid level indicator for a water tank which is convenient for inspection and reading.
[0016] These include liquid level identification components and auxiliary lighting components.
[0017] The liquid level indicator adopts a float level gauge, which is mainly composed of a float inside the water tank, a scale outside the water tank, a float outside the water tank, and a connection line between the float and the float. The external scale has a corresponding height scale mark, and the float can slide up and down in the slide groove of the external scale. When the liquid level changes, the internal float drives the external float to slide up and down, and the corresponding liquid level height indication can be obtained through the different heights of the external float corresponding to the external scale.
[0018] The visible surface of the external scale and the external float is formed into a smooth reflective surface. The reflective material is processed or pasted, such as silver reflective paper. The smooth reflective surface formed does not fade during use, and the scale marking is clear.
[0019] The auxiliary lighting component includes a controller, a sensor and a light-emitting element. The controller is electrically connected to the sensor and the light-emitting element.
[0020] The light emitting element may be an LED light emitting device, and may be a plurality of single LEDs or an LED light strip.
[0021] The light-emitting parts can be arranged along the external scale. When the light-emitting parts are in lighting operation, they can provide lighting brightness in the area of the external scale, and the external scale and the external float can produce a reflection effect and be clearly visible.
[0022] The sensor uses a sound collector or an infrared sensor to collect ambient sound. When the sound exceeds a certain decibel value, it can trigger the lighting control of the light-emitting component.
[0023] In addition, when the infrared sensor senses a high-temperature object that is different from the ambient temperature, it can also trigger the lighting control of the light-emitting component.
[0024] By using a sound collector or infrared sensor, when the inspector approaches the water tank within a certain distance, an induction signal can be generated to trigger the lighting of the light-emitting device. After the light-emitting device is lit, the visible surface of the external scale and external float is clearly visible due to the reflection effect, which can realize the accurate reading of the liquid level during nighttime inspections. The range of the sound collector or infrared sensor can be set to within 10 meters.
[0025] In addition, a corresponding timing unit can be set in the controller, and the night working time period can be set through the timing unit, such as 19:00-6:00. During the corresponding time period, the sound collector or infrared sensor can be enabled to trigger the luminous lighting. Outside the corresponding night working time period, the sound collector or infrared sensor is disabled to trigger the luminous lighting, so that the luminous lighting is only available at night.
[0026] The auxiliary lighting components can also be equipped with corresponding wireless communication modules, which are connected to the controller. The wireless communication modules are used to establish a communication connection with the handheld inspection terminal of the staff. The handheld inspection terminal is equipped with corresponding inspection software. By operating the inspection software to issue instructions, the instructions can also control the lighting of the light-emitting parts after being transmitted to the controller. The wireless communication module allows the staff to control the lighting of the light-emitting parts as needed, and can be remotely controlled at a long distance. It can also provide effective reading for environmental areas that are inconvenient for personnel to approach, saving workload. The height of the outdoor water storage tank in the power plant area is about 8-10 meters. Wireless communication can be used to operate within a range of 50 meters, which can ensure visual observation effects.
[0027] In specific applications,
[0028] During the day when the ambient light is sufficient, the staff can clearly read the reflective external scale and external float by visual inspection at a certain distance. In special circumstances, such as rainy days and when the ambient light is dim, the handheld terminal can also be used to remotely control the luminous lighting to clearly read the reflective external scale and external float.
[0029] When the ambient light is insufficient at night, the sensing circuit starts to work during the working period preset by the timing unit. When the staff is at a certain approach distance, the sensing personnel approach triggers the start of the luminous lighting, and the external scale and external float with reflective effect can be clearly read. If needed, the luminous lighting can also be turned on remotely through the handheld terminal to achieve clear reading of the external scale and external float with reflective effect.
[0030] Finally, it should be noted that the above description is only an explanation of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail, those skilled in the art can still modify the technical solutions described above or replace some of the technical features with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
