[0001] The utility model relates to the technical field of fog guns, and more specifically, it belongs to a special rotary device for the fog gun of a dust suppression vehicle. Background Art

[0002] In order to solve the dust pollution problems in industries such as construction, mining, and chemical industry, dust suppression vehicles are often used to spray water mist through fog guns to achieve the effect of dust reduction. However, in actual operation of traditional dust suppression vehicles, manual control of the rotation angle of the fog gun by a remote controller is required, and the following problems exist in the use process:

[0003] (1) By manually remotely controlling the left - right rotation of the fog gun, the spraying is uneven, resulting in a limited coverage area and unable to cover a large - range area;

[0004] (2) Manual remote control operation requires operators to have high operation skills and experience, and has a strong dependence on labor, which to a certain extent limits the use range and efficiency of the dust suppression vehicle. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies of the above - mentioned traditional technologies, and provide a special rotary device for the fog gun of a dust suppression vehicle, so as to achieve the purpose of reducing labor dependence and improving the spraying uniformity of the fog gun.

[0006] The special rotary device for the fog gun of the dust suppression vehicle provided by the utility model includes a fixed seat, a rotating seat, a connecting disc, a rotation driving component, a position sensor, and a position remote controller; the fixed seat and the rotating seat are concentric disc structures; a connecting disc is arranged at the center of the lower part of the rotating seat; a rotating groove matched with the connecting disc is opened on the upper end surface of the fixed seat; the rotating seat is rotationally matched through the connecting disc and the rotating groove and is arranged above the fixed seat; the rotation driving component is fixedly connected with the rotating seat;

[0007] A positioning groove is opened on one side of the lower end surface of the rotating seat; a plurality of accommodation grooves are opened on the upper end surface of the fixed seat in an annular and equally - angled distribution centered on its center; position sensors are respectively arranged in the accommodation grooves; the fixed seat also has a wiring hole penetrating through its lower end surface at the bottom end surface of the accommodation groove;

[0010] Further, the rotation driving component includes a rotating rod and a rotating motor; one side of the connecting disk away from the rotating seat is mechanically connected to one end of the rotating rod; a rotating hole penetrating the lower end surface and the rotating groove is formed in the center of the fixed seat; one end of the rotating rod away from the rotating seat extends below the fixed seat through the rotating hole and is mechanically connected to the output rod of the rotating motor.

[0011] A special rotating device for the fog cannon of a dust suppression vehicle provided by the present utility model uses a fixed seat and a rotating seat with a concentric disk structure as the rotating support components, and is additionally provided with a position sensor and a position remote control; the position remote control is respectively paired with the position sensor and the original fog cannon control remote control through Bluetooth for data transmission to realize signal connection among the three; the position sensors are arranged in an annular array at equal angles in the accommodating groove formed on the upper end surface of the fixed seat, and the ultrasonic ranging module is adopted for the position sensors. A positioning groove is formed on the lower end surface of the rotating seat.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0023] The utility model provides a special rotating device for the fog cannon of a dust suppression vehicle, which includes a fixed seat 1, a rotating seat 2, a connecting disc 3, a rotation driving component, a position sensor 4 and a position remote controller 5. The fixed seat 1 is fixedly connected to the driving platform of the dust suppression vehicle; the rotating seat 2 is fixedly connected to the lower part of the fog cannon support.

[0024] The fixed seat 1 and the rotating seat 2 are concentric disc structures. A connecting disc 3 is machined at the center of the lower part of the rotating seat 2; a rotating groove 11 matching with the connecting disc 3 is formed on the upper end surface of the fixed seat 1; the connecting disc 3 is rotationally matched in the rotating groove 11 through a bearing; the rotating seat 2 is rotatably arranged above the fixed seat 1 through the cooperation of the connecting disc 3 and the rotating groove 11. The rotation driving component includes a rotating rod 6 and a rotating motor 7. One side of the connecting disc 3 away from the rotating seat 2 is mechanically connected to one end of the rotating rod 6. A rotating hole 14 penetrating through its lower end surface and the rotating groove 11 is formed at the center of the fixed seat 1. One end of the rotating rod 6 away from the rotating seat 2 extends below the fixed seat 1 through the rotating hole 14 and is mechanically connected to the output rod of the rotating motor 7. The rotating motor 7 is fixedly connected to the driving platform of the dust suppression vehicle through an existing support device.

[0025] As can be seen from the above, by driving the rotating motor 7, the rotating rod 6 is driven to rotate, the rotating rod 6 drives the connecting disc 3 to rotate, and then the rotational movement of the rotating seat 2 above the fixed seat 1 is realized, thereby driving the fog cannon to rotate.

[0026] A positioning groove 21 is formed on one side of the lower end surface of the rotating seat 2, and the position of the positioning groove 21 corresponds to the position of the muzzle of the fog cannon.

[0027] Receiving grooves 12 are formed on the upper end surface of the fixed seat 1, which are annularly arranged at equal angles with its center as the center. The position sensors 4 are respectively fixedly connected in the receiving grooves 12 by screws. Referring to the attached Figure 4 , taking twelve position sensors 4 set in this embodiment as an example, they are the first position sensor 401, the second position sensor 402, the third position sensor 403, the fourth position sensor 404... the tenth position sensor 410, the eleventh position sensor 411 and the twelfth position sensor 412; among them, the twelfth position sensor 412 is at the twelve o'clock direction, corresponding to the front direction of the dust suppression vehicle. The fixed seat 1 also has a wire passing hole 13 penetrating through its lower end surface at the bottom end surface of the receiving groove 12, which is convenient for the power supply wires of the position sensors 4 to extend below the fixed seat 1 to be connected to the power supply.

[0028] The position sensor 4 includes an ultrasonic ranging module 41 and a first Bluetooth communication module 42 connected to the ultrasonic ranging module 41 for Bluetooth signal transmission. The position remote controller 5 includes a main control chip 51 and a second Bluetooth communication module 52 connected to the main control chip 51 for Bluetooth signal transmission. The position sensor 4 and the position remote controller 5 are paired and connected through the first Bluetooth communication module 42 and the second Bluetooth communication module 52 to achieve signal transmission between the two. The position remote controller 5 is also paired and connected to the original fog cannon control remote controller 8 through the second Bluetooth communication module 52 to achieve signal transmission between the two. Among them, the ultrasonic ranging module 41 can adopt the existing HC-SR04 model, and the main control chip 51 can adopt the existing AT89C51 series single-chip microcomputer.

[0029] As can be seen from the above, the position sensor 4 uses the ultrasonic ranging module 41 to emit different signals to the rotating seat 2 above it by ranging. Since the position of the positioning groove 21 on the lower end surface of the rotating seat 2 and other positions corresponding to the position sensor 4 are at different distances from the position sensor 4, the ultrasonic ranging module 41 emits different signals by detecting the positioning groove 21. In specific implementation, the operator determines the rotation angle by selecting any two position sensors 4. The two position sensors 4 feed back the position signals of the detected positioning groove 21 to the position remote controller 5. The position remote controller 5 sends a control signal to the original fog cannon control remote controller 8 through the feedback signal, so that the original fog cannon control remote controller 8 controls the rotation motor 7 to change the rotation direction, realizing the reciprocating rotation movement of the rotating seat 2 within the rotation angle defined by the two position sensors 4, and then realizing the automatic reciprocating rotation of the fog cannon within the defined rotation angle for spraying. Compared with the prior art, this solution reduces the dependence on manual labor, improves the operation convenience, expands the use range and working efficiency of the dust suppression vehicle; moreover, the staff can select the number of position sensors 4 according to actual needs, realizing the fine control of the rotation angle of the fog cannon, making the spraying more uniform and expanding the spraying coverage range of the fog cannon.

[0030] The specific usage mode and function of this embodiment:

[0031] In this embodiment, the position sensors 4 at the 3 o'clock and 10 o'clock positions are selected as examples, namely the third position sensor 403 and the tenth position sensor 410. It is set that the fog cannon sprays in the direction from the 3 o'clock position to the 10 o'clock position. The third position sensor 403 is set as the starting point, and the tenth position sensor 410 is set as the ending point. First, the operator operates the position remote control 5 to turn on the third position sensor 403 and the tenth position sensor 410, and sets the third position sensor 403 as the starting point and the tenth position sensor 410 as the ending point. Then, click to start working. The position remote control 5 sends a control signal to the original fog cannon control remote control 8. The original fog cannon control remote control 8 controls the rotation motor 7 to work clockwise, driving the fog cannon to rotate clockwise until the positioning groove 21 rotates above the third position sensor 403. When the third position sensor 403 detects the positioning groove 21, it sends a signal to the position remote control 5. After receiving the signal from the third position sensor 403, the position remote control 5 sends a signal to the original fog cannon control remote control 8. The original fog cannon control remote control 8 controls the rotation motor 7 to rotate towards the tenth position sensor 410, that is, continue to rotate clockwise. When the positioning groove 21 rotates above the tenth position sensor 410, the tenth position sensor 410 sends a signal to the position remote control 5. After receiving the signal from the tenth position sensor 410, the position remote control 5 sends a signal to the original fog cannon control remote control 8. The original fog cannon control remote control 8 controls the rotation motor 7 to change the rotation direction and rotate towards the third position sensor 403, that is, rotate counterclockwise. When the positioning groove 21 rotates above the third position sensor 403 again, after the third position sensor 403 detects the positioning groove 21, it sends a signal to the position remote control 5. After receiving the signal from the third position sensor 403, the position remote control 5 sends a signal to the original fog cannon control remote control 8. The original fog cannon control remote control 8 controls the rotation motor 7 to change the rotation direction and rotate towards the tenth position sensor 410, that is, rotate clockwise. In this way, the fog cannon rotates reciprocally within the set angle for spraying and dust suppression.

[0032] In summary, compared with the prior art, the present utility model realizes the automatic rotation of the fog cannon, reduces the dependence on manual labor, improves the operation convenience, expands the use range and working efficiency of the dust suppression vehicle; at the same time, through the fine control of the rotation angle of the fog cannon, the spraying is made more uniform, and the spraying coverage range of the fog cannon is expanded.
