[0044] Example 1

[0045] like Figures 1 to 6 As shown, the present invention provides an automatic purge device for a liquid level gauge, which includes a liquid level gauge body 1, an air duct module 2 and a fan module 3. The air duct module 2 is a double-layer hollow structure, the air duct module 2 is sleeved on the liquid level gauge body 1, and a conical opening is provided at the bottom end of the air duct module 2. The fan module 3 is installed outside the air duct module 2.

[0046] The technical solution of the present invention is to install the purging device on the liquid level meter body 1, wherein the outermost fan module 3 provides purging power, compress the wind provided by the fan module 3 through the air duct module 2, and finally blow the wind out from the conical port at the bottom of the air duct module 2, thereby purging the surface of the liquid level meter probe. The automatic purging device of the liquid level meter can reduce the time cost of manual operation, eliminate the safety hazards of manual cleaning, and the purging device is simple and reliable in design, which can ensure safe production.

[0047] The air duct module 2 includes an inner air duct 202 and an outer air duct 201. The outer air duct 201 is provided with an air inlet, which is connected to the fan module 3. The bottom of the inner air duct 202 and the bottom of the outer air duct 201 are tapered and narrowed. The wind is compressed by the tapered narrowing of the bottom of the inner air duct 202 and the bottom of the outer air duct 201, increasing the flow rate and wind pressure, so as to better achieve the purge of the liquid level meter probe.

[0048] The inner layer air duct 202 is connected to the top of the outer layer air duct 201. The air of the air duct module 2 enters from the air inlet, and then part of the air goes directly vertically downward and is sent out from the bottom of the air duct module 2 on this side, and the other part of the air first passes through the top of the horizontal air duct module 2, that is, the hollow channel formed by the top of the inner layer air duct 202 and the top of the outer layer air duct 201, and then goes vertically downward and is sent out from the bottom of the air duct module 2 on the other side of the air inlet.

[0049] The fan module 3 includes a fan component, an air outlet 301 and a fixed slot 302. The air outlet 301 is arranged on the back of the fan component, the air outlet 301 is connected with the air inlet, and the fan component is installed on the air duct module 2 through the fixed slot 302. Specifically, a power module interface and a card slot are arranged on the air duct module 2. The modular design can make it easier to overhaul and replace the equipment, and can save costs through partial replacement, that is, only replace the broken module or broken component, without directly replacing the entire equipment.

[0050] The fan module 3 also includes a power module slot 303, which is also installed on the back of the fan component. Specifically, the power supply of the fan module 3 uses the power supply of the liquid level meter body 1, which is a 12V power supply.

[0051] The fan module 3 also includes a rainproof component 304, which is mounted on the top of the fan component. The specific structure of the rainproof component 304 in this embodiment is as follows: Figure 5 As shown, rainwater can be prevented from entering the fan module 3, thereby avoiding the influence on the subsequent purge function.

[0052] The conical opening at the bottom of the air duct module 2 is flush with the horizontal position of the liquid level meter probe, so that the wind in the air duct module 2 can be directed to the liquid level meter probe, thereby achieving the purpose of blowing the liquid level meter probe.

[0053] The air duct module 2 is connected to the outside of the liquid level meter body 1 through a flange. The air duct module 2 can also be connected to the outside of the liquid level meter body 1 through other methods.

[0054] The present invention also provides a method for using the automatic purge device for a liquid level gauge, comprising the automatic purge device for a liquid level gauge, and specifically comprising the following steps:

[0055] Step S1: Turn on the power of the fan module 3 to start the fan module 3, wherein the power of the fan module 3 is obtained through the power of the liquid level meter body 1;

[0056] Step S2: The wind enters the air duct module 2 through the fan module 3 and is pressurized from the bottom of the air duct module 2;

[0057] Step S3: The pressurized wind is used to sweep the probe surface of the liquid level meter body 1;

[0058] Step S4: Turn off the power of the fan module 3 to complete the purge.

[0059] Example 2

[0060] like Figure 6 As shown, the difference between Example 2 and Example 1 is that the structure of the bottom end of the air duct module 2 is different. The structure of the bottom end of the air duct module 2 in Example 1 is as follows: Figure 2 As shown, the bottom ends of the inner air duct 202 and the outer air duct 201 are both tapered, and the closing between the two becomes narrower. In Example 2, the inner air duct 202 is cylindrical, and the structure of the outer air duct 201 is the same as that of Example 1, and the purge function of the liquid level meter probe can also be realized.

[0061] The automatic purging device for a liquid level gauge can adapt to different shapes, types, and installation positions of liquid level gauges. The shape of the air duct of the air duct module 2 can be customized according to the shape of the liquid level gauge body 1 .

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
