Description

Technical Field

[0001] This utility model relates to the field of medicine bottles for spraying drones, and in particular to a liquid level sensing device for medicine bottles of spraying drones. Background Technology

[0002] With the booming development of modern agriculture, spraying drones have become an important tool for pest and disease control and crop nutrient supply in farmland due to their high efficiency and convenience.

[0003] Some existing drones rely solely on operator experience to determine the remaining liquid level in the spray bottle. This method is highly subjective and prone to errors, easily leading to insufficient liquid during operation. This forces the drone to frequently return to base for refilling, severely reducing operational efficiency. Although some simple liquid level sensors exist on the market, environmental factors, including strong winds, can cause the liquid in the spray bottle to shake violently during drone flight, significantly compromising the stability and reliability of the device. This fails to meet the requirements of long-term, efficient, and precise operation for spraying drones. Therefore, a liquid level sensor for spraying drone spray bottles is proposed to solve the above problems. Utility Model Content

[0010] The stabilizing component also includes a mounting groove, which is located at the front of the anti-sway plate, and the mounting tube slides through the inner wall of the mounting groove.

[0011] As a further description of the above technical solution:

[0012] The partition is hollow in the middle, and the radius of the hollow part is larger than the radius of the lower part of the capacitive sensor.

[0013] As a further description of the above technical solution:

[0014] The connecting wire of the capacitive sensor runs through the inside of the fixed cover.

[0015] As a further description of the above technical solution:

[0016] The lower part of the fixed cover contacts the upper part of the capacitive sensor.

[0022] 1. In this utility model, a capacitive sensor is used to measure the liquid level in a medicine bottle. Multiple anti-sway plates are set up, and the through holes on adjacent anti-sway plates are at different positions. When the liquid in the medicine bottle shakes, the liquid passes through the through holes at different positions, which can buffer and disperse the shaking energy multiple times, effectively reducing the interference of liquid shaking on the measurement accuracy, ensuring that the capacitive sensor can measure stably during the flight of the drone, and improving the measurement accuracy.

[0023] 2. In this utility model, the fixed cover is threadedly connected to the box body, making the entire device tightly connected. A groove is opened on the lower outer side of the mounting tube to facilitate connection with the box body.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a liquid level sensing device for a spraying drone, comprising a housing 1 for containing liquid pesticide, a sealing cap 2 fixedly connected to the outside of the housing 1 to form a closed space to prevent liquid pesticide leakage and ensure the sealing of the device, a fixing frame 3 provided on the upper part of the housing 1 for securely installing the device on the spraying drone, and a liquid outlet pipe 6 provided on the lower part of the housing 1 as a channel for liquid pesticide to flow out, transporting the liquid pesticide in the housing 1 to the spraying system of the spraying drone to realize the spraying operation on crops. A fixing mechanism is provided on the inner wall of the housing 1, the fixing mechanism including a fixing component 4 and a stabilizing component 5.

[0032] Reference Figure 1 - Figure 3The fixing component 4 includes a mounting tube 41 inserted into the inner wall of the housing 1, which provides mounting support for the capacitive sensor 44 and ensures its stable position within the housing 1. In conjunction with the stabilizing component 5, it reduces the impact of shaking on the measurement. The capacitive sensor 44 is inserted into the upper part of the mounting tube 41. Based on the capacitance change caused by the change in liquid level, the liquid level information is converted into an electrical signal, thereby obtaining liquid quantity data and providing operators with accurate information on the remaining liquid quantity. This technology is existing technology, so it will not be described in detail. A sealing gasket 45 is provided at the contact point between the capacitive sensor 44 and the mounting tube 41 to prevent liquid leakage and ensure the normal operation of the capacitive sensor 44.

[0033] Reference Figure 1 - Figure 3 A partition 46 is fixedly connected to the inner wall of the mounting tube 41, and the lower part of the capacitive sensor 44 passes through the partition 46. The middle part of the partition 46 is hollow, and the radius of the hollow part is larger than the radius of the lower part of the capacitive sensor 44. This not only does not hinder the lower part of the capacitive sensor 44 from passing through, but also blocks liquid sloshing to a certain extent. Water inlet holes 43 are opened at both the upper and lower parts of the partition 46, so that the liquid can smoothly contact the capacitive sensor 44, ensuring that the capacitive sensor 44 can generate corresponding capacitance changes according to the liquid level changes, thereby realizing the measurement of liquid volume. A fixing cover 42 is threadedly connected to the upper part of the housing 1 near the mounting tube 41. The lower part of the fixing cover 42 contacts the upper part of the capacitive sensor 44. The connecting wire of the capacitive sensor 44 passes through the inside of the fixing cover 42, pressing and fixing the capacitive sensor 44 to the mounting tube 41 to ensure a tight connection. The connecting wire of the capacitive sensor 44 passes through its inside, which plays a role in protecting the circuit and preventing the circuit from being damaged and affecting signal transmission.

[0034] Reference Figure 2 and Figure 4 The stabilizing component 5 includes an anti-sway plate 51 fixedly connected to the inner wall of the housing 1. The upper part of the anti-sway plate 51 has a through hole 52. There are multiple sets of anti-sway plates 51, and the through holes 52 on adjacent sets of anti-sway plates 51 are opened in different positions. The anti-sway plate 51 is made of plastic. When the liquid sloshes, the sloshing energy is buffered and dispersed multiple times through the through holes 52 at different positions, effectively reducing the interference of liquid sloshing on the measurement accuracy of the capacitive sensor 44. The plastic material has a certain elasticity, which can buffer the impact force of the liquid and prevent chemical reaction with the liquid. The edge of the anti-sway plate 51 has a through groove 53 to prevent the liquid from accumulating on the side of the anti-sloshing plate 51. The stabilizing component 5 also includes a mounting groove 54. The mounting groove 54 is opened at the front of the anti-sloshing plate 51. The mounting tube 41 slides through the inner wall of the mounting groove 54 to provide installation space for the mounting tube 41. The lower outer side of the mounting tube 41 has a groove to facilitate connection and fixation with the housing 1 and to facilitate disassembly during later maintenance.

[0035] Working principle: When the medicine is injected into the box 1, the medicine comes into contact with the capacitive sensor 44 through the water inlet 43 at the top and bottom of the partition 46. Due to the different liquid levels, the capacitance value formed between the capacitive sensor 44 and the medicine will change. The capacitive sensor 44 converts this capacitance change into an electrical signal. The electrical signal is transmitted to the subsequent signal processing unit through the connecting wire that passes through the inside of the fixed cover 42. During the flight of the drone, the medicine in the bottle will shake due to the movement of the drone.

[0036] At this time, the stabilizing component 5 comes into play. Multiple anti-sway plates 51 are fixed to the inner wall of the box 1. The through holes 52 on adjacent anti-sway plates 51 are in different positions. When the swaying liquid flows through these through holes 52, its swaying energy is buffered and dispersed multiple times. The anti-sway plates 51 are made of plastic material and have a certain elasticity, which can further buffer the impact force of the liquid and avoid chemical reaction with the medicine. The through grooves 53 on the edge of the anti-sway plate 51 can prevent the medicine from accumulating on the side and affecting the anti-sway effect.

[0037] In addition, the baffle 46 in the mounting tube 41 can block liquid sloshing to a certain extent, ensuring that the capacitive sensor 44 can still measure stably when the liquid is sloshing, reducing the interference of sloshing on measurement accuracy.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
