Figure 1 is a partial cross-sectional view of the liquid level gauge 300 of the movable platform 10 in a measuring position according to an embodiment of the present invention. FIG. 2 is an enlarged view of part A of the movable platform 10 of FIG. 1 . FIG. 3 is a partial enlarged view of the liquid level gauge 300 of the movable platform 10 in the non-measuring position according to the embodiment of the present invention. Referring to Figures 1, 2 and 3, the movable platform 10 includes a body 100, a container 200 and a liquid level gauge 300. The container 200 is provided with a liquid storage chamber 210 for containing liquid, and the container 200 is detachably connected to the body 100 . The liquid level gauge 300 is movably connected to the body 100, and the liquid level gauge 300 is used to measure the liquid level of the liquid. Wherein, the liquid level gauge 300 is configured to move between a measuring position and a non-measuring position; when the liquid level gauge 300 is located at the measuring position, the liquid level gauge 300 can measure the liquid level in the liquid storage chamber 210; when the liquid level gauge 300 is located at the measuring position, When the position meter 300 is in the non-measuring position, the container 200 can be detached from the body 100 .

In some embodiments, the movable platform 10 may be a spraying device such as a plant protection drone or an unmanned vehicle.

It should be noted that the liquid level of the liquid is the height of the liquid level 20 . The container 200 is configured to contain liquid, and the liquid level gauge 300 is used to measure the height of the liquid level 20 of the liquid to be measured in the liquid storage chamber 210. The height of the liquid level 20 can be measured in a non-contact manner. This non-contact method The detection method can be measured based on the principle that the detection signal will be reflected at the interface of different media. The actual height of the liquid level 20 can be measured through reflection time, reflection angle and other parameters, and then the amount of the remaining liquid to be measured in the liquid storage chamber 210 can be known. , the liquid level measurement obtained by using the probe 320 based on this principle has high accuracy and strong reliability.

Further, the body 100 may be provided with a mounting component, the mounting component is provided with a mounting groove, and the container 200 may be at least partially located in the mounting groove.

Further, the liquid can be water, aqueous solution or other solutions, and can be specifically selected according to the specific usage scenario of the movable platform 10 . For example, when the movable platform 10 is a plant protection drone, the liquid can be pesticides.

Furthermore, no matter when the liquid level gauge 300 is in a measuring position or a non-measuring position, the probe 320 will not be in direct contact with the liquid, thus avoiding the corrosion problem of the liquid level gauge 300 and extending the service life of the liquid level gauge 300 .

The movable platform 10 in this embodiment uses a liquid level gauge 300 to achieve non-contact measurement of the liquid level. The liquid level gauge 300 is movably connected to the body 100. When the container 200 needs to be disassembled from the body 100 , just move the liquid level gauge 300 to a non-measuring position, which not only enables continuous liquid level measurement, but also solves the corrosive problem of the contact liquid level gauge 300 and improves the measurement accuracy.

FIG. 4 is a schematic structural diagram of the liquid level gauge 300 of the movable platform 10 in the measurement position according to the embodiment of the present invention. FIG. 5 is a structural schematic diagram of the movable platform 10 of FIG. 4 in different viewing directions. Referring to FIGS. 4 and 5 , when the liquid level gauge 300 is located at the measuring position, the separation direction of the container 200 and the body 100 is blocked by the liquid level gauge 300 . When the liquid level gauge 300 is in the non-measuring position, the liquid level gauge 300 deviates from the separation direction of the container 200 and the body 100 so that the container 200 can be separated from the body 100 freely.

It can be understood that the separation direction of the container 200 and the body 100 is blocked by the liquid level gauge 300. In other words, the liquid level gauge 300 is located on the separation path of the container 200 and the body 100, so that the container 200 and the body 100 cannot be separated. That is, when the liquid level gauge 300 is located at the measurement position, the container 200 and the body 100 cannot be disassembled due to the obstruction of the liquid level gauge 300 .

Referring to FIG. 2 , the liquid level gauge 300 includes a bracket 310 and a probe 320 . The bracket 310 is movably connected to the body 100 . The probe 320 is installed on the bracket 310, and the probe 320 is used to measure the liquid level of the liquid.

Further, the probe 320 can be used to emit a detection signal to the liquid. The detection signal can be transmitted through the container 200 and directed to the liquid. The detection signal can be reflected after encountering the liquid surface 20 of the liquid. The probe 320 can be placed on the path after the reflection of the detection signal. on, so that the probe 320 can receive the reflected detection signal, and then detect the reflected distance by the detection signal to obtain the liquid level. The liquid level measurement obtained by the probe 320 using this principle has high accuracy and strong reliability.

Further, the material of the container 200 is at least partially configured as a wave-transmissive material, which can transmit the detection signal. The wave-transparent material refers to a material that can transmit electromagnetic waves and hardly change the properties (including energy) of the electromagnetic waves. The setting of the wave-transmitting material can reduce the loss of the detection signal on the propagation path, improve the measurement accuracy, and ensure that the results obtained by the liquid level meter 300 are accurate and reliable.

In some embodiments, the portion of container 200 opposite probe 320 is made of a wave-transmissive material. The relative here refers to the relative position, that is to say, the container 200 and the probe 320 are at least partially disposed facing each other.

It should be noted that the liquid surface 20 is the interface between the liquid and the air, and has the effect of reflecting the detection signal. After the detection signal is reflected by the liquid surface 20 , the reflected detection signal will transmit through the container 200 and be received by the probe 320 , and then complete the detection of the liquid level 20 height.

In some embodiments, the probe 320 may be located above the level 20 of the liquid.

The liquid level gauge 300 is used to transmit a detection signal to the liquid level to detect the liquid level. The detection signal includes one or more of the following: acoustic wave signal, radar signal and laser signal.

When the liquid level gauge 300 is located at the measuring position, at least part of the bracket 310 can slide out of the receiving cavity 110 and drive the probe 320 to move until the probe 320 moves above the top of the container 200; when the liquid level gauge 300 is located at a non-stop position, When measuring the position, the container 200 can drive the bracket 310 to slide, so that the bracket 310 moves into the receiving cavity 110 , and the probe 320 is located on one side of the container 200 .

Further, when the liquid level gauge 300 is located at the measurement position, the probe 320 moves above the top of the container 200. This arrangement makes the coverage area of the probe 320 become an acceptable area after reflection of the detection signal, so as to ensure that the quantity is relatively large. There will be no blind spots even with a small level gauge 300. In some embodiments, at least one liquid level gauge 300 may be provided to improve measurement accuracy.

Furthermore, when the liquid level gauge 300 is in the non-measuring position, the container 200 can drive the bracket 310 to slide. It can be understood that the container 200 exerts a force on the bracket 310, causing the bracket 310 to move into the receiving cavity 110.

Further, the probe 320 is located on one side of the container 200 , which means that the probe 320 avoids the separation path between the container 200 and the body 100 .

The cavity exits the opening from the L-shaped cavity.

Further, the position of the accommodating tank 220 on the container 200 is higher than the liquid level 20 so that the liquid level gauge 300 can work normally. In order to increase the use space of the container 200, the accommodating groove 220 can be opened at the top of the container 200.

Referring to FIGS. 2 and 3 , the restoring member 330 includes an elastic member 331 . The elastic member 331 is in contact with the bracket 310.
