[0002] In the field of environmental engineering technology, mechanical automation control, etc., especially in the fields of industrial production, construction and transportation, a large amount of dust and harmful gas emissions lead to a decline in air quality, affecting human health and environmental quality.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] The fog cannon device is usually composed of a fog cannon barrel, a water pump, a motor, a control system, and a sensor. By adjusting the angle and height of the fog cannon barrel through the control system, the haze at different heights and directions can be suppressed; at the same time, some fog cannon devices are also equipped with an automatic control system, which can monitor environmental parameters in real time through sensors and automatically adjust the working state of the fog cannon according to the preset parameters; however, there are still some problems with the fog cannon device in practical applications, such as:

[0037] (1) The fog cannon device usually requires manual adjustment of the lifting height, rotation angle and pitch angle through a remote control device, but the human eye is used to judge whether the adjustment is in place. Another way is to control the working time of the motor and lifting mechanism through the control algorithm built into the software to control the lifting height, rotation angle and pitch angle to reach the target value, but the control algorithm requires a certain amount of time to calculate, there is a certain delay, and the corresponding time is different in different situations; even when a fault occurs, it will cause adjustment errors. Therefore, the control accuracy and execution speed of the above methods need to be improved, especially in complex environments and variable working conditions, which are prone to control deviations and slow responses.

[0038] (2) The fog cannon device still has certain limitations in terms of height adjustment and angle adjustment, and cannot meet the requirements for haze suppression in different heights and directions in different scenarios.

[0039] The above questions are explained one by one below.

[0040] The embodiment of the present application provides a dust suppression fog cannon device to solve the problem in the related art that control deviation is easy to occur in the manual remote control adjustment and the algorithm control of the working time adjustment of the motor and the lifting mechanism.

[0041] See also Figure 1-Figure 4 , a dust suppression fog cannon device, comprising:

[0042] A lifting assembly 1 is mounted on a base 2, and a lifting platform 3 is provided on the top thereof, and a rotating motor is provided on the lifting platform 3; a first proximity switch 12 for feedback of whether the lifting assembly 1 has been lowered to a certain height is provided on the base 2;

[0043] The rotating platform 4 is located above the lifting platform 3 and connected to the rotating motor; the lifting platform 3 is provided with a second proximity switch 5 which can provide feedback on the rotation angle of the rotating platform 4;

[0044] The enclosure 6 is fixedly connected to the top of the rotating platform 4, and is provided with a pitch adjustment mechanism 7 therein; the pitch adjustment mechanism 7 is connected to a fog cannon barrel 8 located above the enclosure 6; the outer side of the enclosure 6 is connected to a third proximity switch 10 for feedback of the pitch angle of the fog cannon barrel 8;

[0045] The control component 11 is connected to the first proximity switch 12, the second proximity switch 5, the pitch adjustment mechanism 7, the third proximity switch 10, the lifting component 1, and the rotating motor.

[0046] Through the above structure, when it is necessary to adjust the height, rotation angle and pitch angle to the target lifting height, first confirm and set the position of the first proximity switch 12, the second proximity switch 5 and the third proximity switch 10, that is, the position corresponding to the height, rotation angle and pitch angle of the target lifting height; then only need to turn on the rotating motor, the lifting component 1 and the pitch adjustment mechanism until the feedback signals of the first proximity switch 12, the second proximity switch 5 and the third proximity switch 10 are received, which means that the adjustment has been completed accurately. The above process does not need to consider the preset time of algorithm control, and whether the adjustment is completed by manual judgment. In this way, the operating power speed of the rotating motor, the lifting component 1 and the pitch adjustment mechanism can be set as large as possible, speeding up the adjustment process, saving time, effectively ensuring the adjustment accuracy, and avoiding the problem of control deviation. Since the above proximity switches only have two states: disconnected or connected, this can eliminate the need for excessive calculations, save calculation time, and solve the problem of slow response.

[0047] In some preferred embodiments, in order to ensure a stable adjusted posture after the pitch adjustment mechanism 7 is adjusted, the setting of the pitch angle locking mechanism is omitted, and refer to the following description:

[0048] Two oblique support rods are provided on the outer side of the enclosure 6; the bottom ends of the oblique support rods are connected to the enclosure 6; the top ends of the oblique support rods are inclined upward and are installed with the third proximity switch 10; one oblique support rod is correspondingly installed with one third proximity switch 10;

[0049] The connection line between the two third proximity switches 10 and the central axis of the fog cannon barrel 8 are located on the same vertical plane.

[0050] The two oblique support rods with the third proximity switch 10 can play a supporting role, limit the two points in the central axis direction of the fog cannon barrel 8, ensure that the pitch angle does not change, and also provide an installation position for the third proximity switch 10.

[0051] In some preferred embodiments, in order to solve the problem that the traditional fog cannon device still has certain limitations in height adjustment and angle adjustment and cannot meet the requirements of haze suppression in height and direction in different scenes, the following settings are provided:

[0052] First, for the third proximity switch 10;

[0053] Vertical installation areas are respectively provided on the two side surfaces of the surrounding tube 6 corresponding to the connection with the oblique support rods; each vertical installation area is provided with a plurality of first installation holes arranged vertically at intervals;

[0054] A connecting portion is provided at the bottom end of the oblique support rod, and the connecting portion is selectively connected to the connecting portion corresponding to a plurality of first mounting holes in the vertical mounting area.

[0055] Under different pitch angle requirements, the pitch adjustment mechanism 7 can adjust the vertical position of the oblique support rod accordingly before being turned on, that is, connect with the corresponding first mounting hole. As for the specific connection method, threaded connection or pin connection can be adopted.

[0056] The reason why the electric lifting mechanism is not used for the vertical movement of the oblique support rod is that it cannot be ruled out that the electric lifting mechanism also has the problem of error control, which will lead to other inaccuracy problems. Of course, if there is a situation where the electric lifting mechanism can accurately control the lifting, this application does not exclude this situation.

[0057] Second, for the first proximity switch 12;

[0058] In form 1, a mounting plate 15 is provided on the base 2, and a plurality of second mounting holes are provided on the mounting plate 15, and the second mounting holes are selectively connected to the first proximity switch 12. The lifting assembly 1 includes a scissor-type hydraulic telescopic mechanism; the plurality of second mounting holes on the mounting plate 15 are spaced apart along the moving direction of the bottom arm of the scissor-type hydraulic telescopic mechanism; and the bottom arm of the scissor-type hydraulic telescopic mechanism is provided with a first protrusion for contacting the first proximity switch 12.

[0059] In form 2, the mounting plate 15 is arranged vertically, and its vertical height is greater than the maximum lifting height of the lifting platform 3; and the plurality of second mounting holes on the mounting plate 15 are distributed at intervals along its vertical height direction. For other lifting component structures.

[0060] Two embodiments are given above, and the key point is that different installation positions can be preset to meet the needs of different height adjustment, and the signal can be fed back as long as the first proximity switch 12 contacts the first protrusion. The above form 1 is the best embodiment, which can minimize the space occupied by the installation plate 15.

[0061] Third, for the second proximity switch 5;

[0062] Form 1: A plurality of third mounting holes 13 are provided on the lifting platform 3 and are distributed in a circle with the rotation center axis of the rotating platform 4 as the center; a second proximity switch 5 is installed in each third mounting hole 13; the plurality of second proximity switches 5 are connected to the control component 11; the control component 11 is used to control the plurality of second proximity switches 5 to be powered on one by one. That is, the position of the second proximity switch 5 needs to be changed in advance.

[0063] Form 2: The lifting platform 3 is provided with a plurality of third mounting holes 13 distributed in a circle with the rotation center axis of the rotating platform 4 as the center; the plurality of third mounting holes 13 are selectively connected to the second proximity switch 5; the side wall of the rotating platform 4 is provided with a second protrusion 14 for contacting the second proximity switch 5. The side wall of the rotating platform 4 is provided with a second protrusion 14 for contacting the second proximity switch 5; this form does not require disassembly and assembly of the second proximity switch 5, and only needs to control the corresponding second proximity switch 5 to turn on the power supply.

[0064] The above two methods are merely implementation methods, but other configuration forms are not excluded.

[0065] In some preferred embodiments, the pitch adjustment mechanism 7 includes a support 700 disposed in the enclosure 6 and fixedly connected to the rotating platform 4; a hinge seat is hingedly provided on the support 700, and the hinge seat is fixedly connected to the fog cannon barrel 8; a tilted telescopic member 701 is provided on the support 700, and the top of the telescopic member 701 is connected to the hinge seat. A fog cannon barrel avoidance gap 9 is provided on the top of the enclosure 6, and the fog cannon barrel avoidance gap 9 is V-shaped. The setting of the fog cannon barrel avoidance gap 9 in conjunction with the oblique support rod can further support the fog cannon barrel 8.

[0066] In some preferred embodiments, the present application further includes a high-pressure water pump with a motor assembly 16, and the high-pressure water pump with a motor assembly 16 is connected to the water inlet pipe of the fog cannon barrel 8 through a high-pressure water pipe.

[0067] The control assembly 11 includes a control box, in which a control box and related circuits are arranged;

[0068] The control box feeds back the position information to the control system through the proximity switch, which can realize real-time monitoring and adjustment of the barrel posture, thereby improving the system's adaptive ability and operating efficiency. Compared with the prior art, the design of the present invention is more intelligent and can better adapt to complex environments and variable working conditions.

[0069] The present invention modularizes the high-pressure water pump with motor assembly 16 and control box and other components, which is not only easy to install and maintain, but also improves the reliability and stability of the system. Compared with the prior art, the design of the present invention is more reasonable and easy to promote and apply.
