Further, the first installation cavity 101 includes an oil cavity 101a for storing fuel and a medium cavity 101b for storing a medium, which are disposed to be spaced apart from each other.

Further, the housing 110 is cone-like, (of course, in other embodiments, the housing 110 may be configured in other shapes, such as a disc shape, etc.), the housing 110 extends downward from the top thereof to form a cylindrical cavity 104 (of course, in other embodiments, the cylindrical cavity 104 may be modified), the middle plate 120 is a plate-like structure, the cylindrical cavity 104 and the middle plate 120 enclose an oil chamber 101a, and the peripheral space of the cylindrical cavity 104, the middle plate 120 and the housing 110 enclose a medium chamber 101 b.

It should be noted that the media chamber 101b is disposed around the oil chamber 101a, i.e., the oil chamber 101a is disposed in the media chamber 101b, mainly based on two aspects, the first aspect is that when the media chamber 101b is disposed at the periphery of the oil chamber 101a, the media chamber can be coordinated with the spraying outlet of the media, so that the spraying path of the media from the media chamber 101b via the edge of the housing 100 is short, which is beneficial to fully utilizing the media and improving the spraying efficiency and effect of the media, and the second aspect is that when the media chamber 101b is disposed at the periphery of the oil chamber 101a, i.e., the media still exists between the fuel and the external environment, and the fuel can be well protected by the media.

The embodiment of the utility model provides a carry out rational planning through the inner space to casing 100 for each component of medium sprinkler can correspond and install in corresponding installation intracavity, makes medium sprinkler structurally compacter, thereby makes medium sprinkler accomplish more small and exquisite.

On the other hand, for the connecting structure of the middle plate 120 and the bottom plate 130 with the housing 110, particularly for the connecting structure of the middle plate 120 and the housing 110, it is preferable to enable a sealed connection therebetween. For this, a groove (not shown) may be provided at a corresponding position of the inner wall of the housing 110 so that the middle plate 120 and the bottom plate 130 can be caught in the groove, and further, a packing or the like may be provided in the groove.

As can be seen from the foregoing, the middle plate 120 is mainly used for supporting fuel and medium, the weight of the fuel and medium is generally large, and the middle plate 120 bears a large load under the gravity, which may make it difficult for the middle plate 120 to be stably located in the casing 100.

In this regard, referring to fig. 6 to 7 in combination, in some embodiments, a plurality of middle plate holders 150 are disposed on the bottom plate 130, the height of the middle plate holders 150 is higher than that of other components disposed on the bottom plate 130 (for example, a rotating mechanism 210 to be described later, etc.), and the middle plate holders 150 can support the edges or the edges of the middle plate 120, so that the burden of the middle plate 120 can be shared on the bottom plate 130.

Due to the symmetrical arrangement of the rotating mechanism 210, the driving force of the rotating mechanism 210 can be guaranteed to be uniformly applied to the medium spraying device, so that the medium spraying device can stably rotate.

Of course, considering that the medium spraying device may be affected by manufacturing tolerance, environment, and other factors, so that the medium spraying device is difficult to stably rotate, the magnitude of the driving force generated by the rotating mechanism 210 may be separately controlled, and the driving force relationship is reasonably matched, so that the medium spraying device can stably rotate finally.

Further, the landing gear 600 is provided with universal wheels 610 that provide for rotation of the media spray device while also facilitating shifting of the position of the media spray device.

Referring to fig. 11, the present embodiment also provides a control method for controlling a media spraying device, where the control method includes:

s100, controlling a rotary lifting structure 200 of the medium spraying device to work, so that the medium spraying device rotates and rises to a specified position; and

s200, controlling the medium spraying structure 300 of the medium spraying device to work, so that the medium spraying device sprays the medium.

Specifically, the whole control system in the embodiment of the present invention is shown in fig. 12, and the control system is composed of several parallel branches, specifically, the control system includes a remote control cabinet 400, a main switch S1 connected in series to the circuit where the remote control cabinet 400 is located, the lifting control cabinet 226, a lifting control switch S2 connected in series to the circuit where the lifting control cabinet 226 is located, a spraying control switch S3, the rotating control cabinet 216, and a ganged switch S4 connected in series to the circuit where the rotating control cabinet 216 is located, and further includes a synchronous control cabinet 700. The remote control cabinet 400 and the main switch S1 form a parallel branch, the lifting control cabinet 226 and the lifting control switch S2 form a parallel branch, the spraying control switch S3 forms a parallel branch, the rotating control cabinet 216 and the linkage switch S4 form a parallel branch, and the synchronous control cabinet 700 and the linkage switch S4 form another parallel branch.

When the medium spraying device needs to be started, firstly, the remote control switch S1 needs to be closed, then the K2 of the linkage switch S4 is located at a switching-on position, the K1 is located at a switching-off position, then the two rotating mechanisms 210 can be respectively started through the two rotating control cabinets 216 until the medium spraying device starts to rotate, at the moment, the medium spraying device can shake due to the influences of factors such as manufacturing process, environment and the like, the shaking phenomenon of the medium spraying device can be eliminated by properly adjusting the driving force of the two rotating mechanisms 210, after the spraying device keeps stable rotation, the K2 of the linkage switch S4 is located at the switching-off position and the K1 is located at the switching-on position, the synchronous control cabinet 700 controls the two rotating mechanisms 210 to synchronously increase the thrust force, so that the medium spraying device stably accelerates to a certain degree, the lifting control switch S2 is closed, and the medium spraying device, after the medium spraying device ascends to an aerial designated position under the high-speed rotation condition, the spraying control switch S3 is turned on, the control valve 320 acts, the spraying pipeline 310 is turned on, the medium is continuously ejected from the spraying pipeline 310 at the moment, the whole space is full of the medium, and the perfect medium spraying effect can be realized in the fields of park viewing, forest fixed-point fire extinguishing and pesticide spraying.
