Description

Technical Field

[0001] This application relates to the field of environmental engineering technology, and in particular to a dust suppression fog cannon device. Background Technology

[0002] In the fields of environmental engineering technology and mechanical automation control, particularly in industrial production, construction, and transportation, the emission of large amounts of dust and harmful gases leads to a decline in air quality, impacting human health and environmental quality. To address this challenge, various dust suppression devices have been developed, among which fog cannons are a common type of dust suppression equipment.

[0003] In related technologies, fog cannon devices typically consist of a fog cannon barrel, a water pump, a motor, a control system, and sensors. By adjusting the angle and height of the fog cannon barrel through the control system, fog and haze at different heights and directions can be suppressed. Furthermore, some fog cannon devices are equipped with automatic control systems that can monitor environmental parameters in real time through sensors and automatically adjust the fog cannon's operating status according to preset parameters. However, fog cannon devices still have some problems in practical applications, such as:

[0004] (1) Fog cannon devices usually require manual adjustment of the lifting height, rotation angle, and pitch angle via remote control, but the adjustment is still judged by the naked eye. Another method is to control the working time of the motor and lifting mechanism through the built-in control algorithm of the software to control the lifting height, rotation angle, and pitch angle to reach the target value. However, the control algorithm requires a certain amount of time to calculate, which has a certain delay, and the corresponding time is not the same under different conditions. In addition, when a fault occurs, it will cause the adjustment error. Therefore, the control accuracy and execution speed of the above methods need to be improved, especially in complex environments and variable working conditions, where control deviation and slow response are prone to occur.

[0005] (2) Fog cannon devices still have certain limitations in terms of height and angle adjustment, and cannot meet the requirements of fog suppression at different heights and directions in different scenarios. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Fog cannon devices typically consist of a cannon barrel, water pump, motor, control system, and sensors. By adjusting the angle and height of the cannon barrel through the control system, fog cannons can suppress smog at different heights and directions. Some fog cannon devices are also equipped with automatic control systems that monitor environmental parameters in real time using sensors and automatically adjust the cannon's operating status based on preset parameters. However, fog cannon devices still have some problems in practical applications, such as:

[0037] (1) Fog cannon devices usually require manual adjustment of the lifting height, rotation angle, and pitch angle via remote control, but the adjustment is still judged by the naked eye. Another method is to control the working time of the motor and lifting mechanism through the built-in control algorithm of the software to control the lifting height, rotation angle, and pitch angle to reach the target value. However, the control algorithm requires a certain amount of time to calculate, which has a certain delay, and the corresponding time is not the same under different conditions. In addition, when a fault occurs, it will cause the adjustment error. Therefore, the control accuracy and execution speed of the above methods need to be improved, especially in complex environments and variable working conditions, where control deviation and slow response are prone to occur.

[0038] (2) Fog cannon devices still have certain limitations in terms of height and angle adjustment, and cannot meet the requirements of fog suppression at different heights and directions in different scenarios.

[0039] The following will explain each of the above issues one by one.

[0040] This application provides a dust suppression fog cannon device to solve the problem that control deviations are prone to occur when adjusting the working time of the motor and lifting mechanism manually by remote control or by algorithm control in related technologies.

[0041] Please see Figures 1-4 A dust suppression fog cannon device, comprising:

[0042] The lifting assembly 1 is mounted on the base 2 and has a lifting platform 3 on its top. The lifting platform 3 is equipped with a rotary motor. The base 2 is equipped with a first proximity switch 12 that provides feedback on the lowering height of the lifting assembly 1.

[0043] A rotating platform 4 is located above the lifting platform 3 and is connected to a rotating motor; a second proximity switch 5 is provided on the lifting platform 3 to 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 has a pitch adjustment mechanism 7 inside it; the pitch adjustment mechanism 7 is connected to the fog cannon 8 located above the enclosure 6; a third proximity switch 10 is connected to the outer side of the enclosure 6 to provide feedback on the pitch angle of the fog cannon 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 rotary motor.

[0046] With the above structure, when adjusting to the target lifting height, rotation angle, and pitch angle, the positions of the first proximity switch 12, the second proximity switch 5, and the third proximity switch 10 are first confirmed and set, corresponding to the target lifting height, rotation angle, and pitch angle. Then, simply turn on the rotary motor, lifting assembly 1, and pitch adjustment mechanism until signals are received from the first proximity switch 12, the second proximity switch 5, and the third proximity switch 10. This indicates that the adjustment has been accurately completed. The above process does not require algorithmic control preset time or manual judgment of whether the adjustment is complete. This allows the operating power and speed of the rotary motor, lifting assembly 1, and pitch adjustment mechanism to be set as high as possible, speeding up the adjustment process, saving time, effectively ensuring adjustment accuracy, and avoiding control deviation problems. Since the above proximity switches only have two states, open or closed, excessive calculations are not required, saving calculation time and solving the problem of slow response.

[0047] In some preferred embodiments, to ensure a stable attitude after the pitch adjustment mechanism 7 has been adjusted, the pitch angle locking mechanism is omitted, as described below:

[0048] Two inclined support rods are provided on the outer side of the casing 6; the bottom end of the inclined support rod is connected to the casing 6; the top end of the inclined support rod is inclined upward and a third proximity switch 10 is installed thereon; one third proximity switch 10 is installed on each inclined support rod.

[0049] The line connecting the two third proximity switches 10 is on the same vertical plane as the central axis of the fog cannon 8.

[0050] The two diagonal support rods with the third proximity switch 10 can provide support and limit the two points in the direction of the central axis of the fog cannon 8 to ensure that the pitch angle does not change. They also provide the installation position for the third proximity switch 10.

[0051] In some preferred embodiments, to address the limitations of traditional fog cannons in terms of height and angle adjustment, which prevent them from meeting the requirements for fog suppression at different heights and directions in various scenarios, the following settings are provided:

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

[0053] Vertical installation areas are provided on both sides of the casing 6 that are connected to the diagonal support rod; each vertical installation area is provided with multiple vertically spaced first installation holes;

[0054] The bottom end of the inclined support rod is provided with a connecting part, which is connected to one of the multiple first mounting holes in the vertical installation area.

[0055] Under different pitch angle requirements, before activation, the pitch adjustment mechanism 7 can adjust the vertical position of the inclined support rod, that is, connect it to the corresponding first mounting hole. The specific connection method can be a threaded connection or a pin connection.

[0056] The reason why an electric lifting mechanism was not used for the vertical movement of the inclined support rod is that the possibility of error control issues with the electric lifting mechanism cannot be ruled out, which could lead to other inaccuracies. Of course, if there is an electric lifting mechanism that can precisely control the lifting, this application does not rule out such a situation.

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

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

[0059] In the second configuration, the mounting plate 15 is vertically positioned, and its vertical height is greater than the maximum lifting height of the lifting platform 3; multiple second mounting holes on the mounting plate 15 are spaced apart along its vertical height. This applies to other lifting component structures.

[0060] The above provides two embodiments, the key point being that different installation positions can be preset to meet different adjustment height requirements. A feedback signal is generated as long as the first proximity switch 12 contacts the first protrusion. The first embodiment is the preferred embodiment, as it minimizes the space occupied by the mounting plate 15.

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

[0062] Form 1: The lifting platform 3 has multiple third mounting holes 13 arranged in a circle with the rotation center axis of the rotating platform 4 as the center; each third mounting hole 13 is equipped with a second proximity switch 5; the multiple second proximity switches 5 are connected to the control component 11; the control component 11 is used to control the multiple second proximity switches 5 to be selectively powered on. That is, the position of the second proximity switches 5 needs to be changed in advance.

[0063] Form 2: The lifting platform 3 is provided with multiple third mounting holes 13 arranged in a circle with the rotation center axis of the rotating platform 4 as the center; one of the multiple third mounting holes 13 is 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. In this form, it is not necessary to disassemble the second proximity switch 5; it is only necessary to control the corresponding second proximity switch 5 to turn on the power.

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

[0065] In some preferred embodiments, the pitch adjustment mechanism 7 includes a support 700 disposed within the enclosure 6 and fixedly connected to the rotating platform 4; a hinge seat is hinged to the support 700 and fixedly connected to the fog cannon 8; an inclined telescopic member 701 is provided on the support 700, the top of the telescopic member 701 being connected to the hinge seat. A fog cannon clearance notch 9, which is V-shaped, is provided at the top of the enclosure 6. The fog cannon clearance notch 9, in conjunction with the inclined support rod, can further support the fog cannon 8.

[0066] In some preferred embodiments, this application also includes a high-pressure water pump and motor assembly 16, which is connected to the water inlet pipe of the fog cannon 8 via a high-pressure water pipe.

[0067] Control component 11 includes a control box, which contains a control module and related wiring.

[0068] The control box feeds position information back to the control system via proximity switches, enabling real-time monitoring and adjustment of the barrel's attitude, thereby improving the system's adaptability and operational efficiency. Compared to existing technologies, this invention is more intelligent and better adaptable to complex environments and changing working conditions.

[0069] This application modularizes the high-pressure water pump with motor assembly 16 and control box, which not only facilitates installation and maintenance but also improves the system's reliability and stability. Compared to existing technologies, the design of this invention is more rational and easier to promote and apply.
