[0026] The purpose of the utility model is to provide a tank level gauge device and a liquid storage device, which can utilize the principle of accelerated evaporation to more timely and completely remove condensed water on the probe 12, avoid affecting the sensitivity of the probe 12, and facilitate maintenance.
[0027] Please refer to Figure 1 , Figure 1 The overall structural diagram of the liquid storage device including the tank level gauge device provided in one embodiment of the utility model. Figure 1 As shown, in order to achieve the above purpose, the utility model provides a tank liquid level gauge device, which is used to be arranged above the liquid level 7 in the liquid storage tank 6, and the tank liquid level gauge device includes an ultrasonic level gauge, a pipe 4, a purge pipe 2, and a cleaning member 3;
[0028] The ultrasonic liquid level meter includes a probe 12 (the complete ultrasonic liquid level meter further includes a transmitter 11), the probe 12 is coaxially arranged with the pipe 4, the probe 12 is used to emit ultrasonic waves toward the liquid level 7 in the liquid storage tank 6 and to the liquid level 7, a first opening and a second opening are provided on the side wall of the pipe 4, the purge pipe 2 extends into the first opening, the purge pipe 2 is used to output an airflow and enable the airflow to purge the side of the probe 12 close to the liquid level 7 in the liquid storage tank 6, the cleaning member 3 is used to extend into the second opening, and the cleaning member 3 is used to wipe the side of the probe 12 close to the liquid level 7 in the liquid storage tank 6.
[0029] According to the relevant principles of water evaporation in physics, there are three measures to speed up the evaporation of water:
[0030] (1) Increase the water temperature;
[0031] (2) Increase the contact area between water and air;
[0032] (3) Increase the air flow rate on the water surface.
[0033] Based on this, the utility model is configured in this way, using the purge pipe 2 to blow out gas to increase the air flow rate on the water surface, but the effect of a single purge to remove condensed water is not good enough, so the utility model further uses the cleaning member 3 to extend into the second opening to wipe the probe 12, and the condensed water on the probe 12 is diluted by wiping, thereby increasing the contact area between water and air, thereby accelerating the evaporation of the condensed water, achieving more timely, simple and more thorough removal of the condensed water on the probe 12, and facilitating the maintenance of the ultrasonic level meter.
[0034] Furthermore, in order to further accelerate the evaporation of water, the utility model proposes heating measures for condensed water based on the idea of increasing the temperature of water, and there are mainly two ideas.
[0035] The first idea is based on the connection between the ultrasonic level meter and the pipe 4 by means of a flange 10, in which case the flange 10 is required to be made of metal, and the flange 10 is connected to a heating element 5, and the heating element 5 is used to transfer heat to the probe 12 through the flange 10. It should be understood that in general, the operating temperature requirement of the ultrasonic level meter is -20°C to 60°C, and it cannot be overheated, so the heating temperature of the heating element 5 should be controlled below 60 degrees Celsius.
[0036] The second idea is to let the purge pipe 2 blow out high-temperature gas. Similarly, the temperature of the gas blown out by the purge pipe 2 should be below 60 degrees Celsius.
[0037] Furthermore, it also includes a guide rail 30, the guide rail 30 is connected to the second opening, and the cleaning member 3 can reciprocate on the guide rail 30, so that the cleaning member 3 can wipe the side of the probe 12 close to the liquid level 7 in the liquid storage tank 6. In an exemplary embodiment, the relative position of the second opening can be customized according to the height of the side of the probe 12 close to the liquid level 7, so that the cleaning member 3 can wipe the probe 12 by reciprocating.
[0038] Furthermore, the pipe 4 has a preset length and a preset inner diameter, so that the inner wall of the pipe 4 avoids the ultrasonic wave emitted by the probe 12 , thereby avoiding affecting the detection of the probe 12 .
[0039] Preferably, the pipe 4 is also provided with a vent hole 40, which allows the purge gas to flow out smoothly, avoids increasing the gas pressure in the tank, and forms a gas loop.
[0040] Preferably, a valve 21 is provided on the purge pipe 2, and the valve 21 is used to control the flow of gas, thereby controlling the purge.
[0041] The utility model also provides a liquid storage device, including a liquid storage tank 6 and any of the above-mentioned tank liquid level gauge devices, wherein the liquid storage tank 6 is used to store liquid, the tank liquid level gauge device is arranged above the liquid level 7 in the liquid storage tank 6, and the probe 12 is close to the liquid level 7 in the liquid storage tank 6 and is used to emit ultrasonic waves to the liquid level 7.
[0042] Since the liquid storage device includes any of the above-mentioned tank level gauge devices, the liquid storage device can use the purge pipe 2 to blow out gas and the cleaning member 3 to extend into the second opening to wipe the probe 12, thereby achieving more timely, simple and thorough removal of condensed water on the probe 12, thereby facilitating the maintenance of the ultrasonic level gauge.
[0043] Since the liquid storage device provided by the present invention and the tank liquid level gauge device described above belong to the same inventive concept, the liquid storage device provided by the present invention has all the advantages of the tank liquid level gauge device described above, and therefore the beneficial effects of the liquid storage device provided by the present invention will not be described one by one here.
