Description

Technical Field

[0001] This utility model belongs to the field of fog cannon tilt angle technology, and in particular relates to a key signal transmission device for intelligent fog cannons. Background Technology

[0002] In recent years, with the increasing awareness of environmental protection and the continuous advancement of related policies and measures, the requirements for the performance of fog cannon equipment have been rising, especially in terms of protecting human health and the ecological environment. To better serve these goals, the research and development and performance optimization of fog cannon technology has become an important task.

[0003] Modern dust suppression fog cannons are characterized by long range, wide coverage, flexible operation, and high degree of automation. They effectively control dust pollution, reduce the concentration of suspended particulate matter in the air, improve the working environment, and prevent industrial accidents, playing an irreplaceable role in ensuring safe production and maintaining environmental hygiene. Therefore, dust suppression fog cannons have been widely used in various industries and scenarios, including steel smelters, coal logistics parks, open-pit mines, blasting sites, enclosed unloading areas, port truck unloading points, dump truck operating areas, large loading areas, coastal port loading and unloading areas, coal and ore transfer yards, and bulk material handling sites for dust control. They are also suitable for dust control during building demolition, dust prevention during garbage transportation, localized dust control from mechanical operations, and dust control on roads used for heavy vehicle transportation. Furthermore, they are widely used for dust suppression, humidification, cooling, and disinfection in airports, highways, stations, docks, public areas, stadiums, and high-temperature work sites.

[0004] As the application scope of fog cannons continues to expand, the requirements for their overall performance are also increasing, and the technical standards of related supporting facilities are rising accordingly. In particular, remote-controlled fog cannons, due to their high efficiency and operational flexibility, are gradually becoming the preferred equipment for dust suppression in material sheds, mines, and other similar locations. However, intelligent fog cannons rely on a precise signal transmission system, especially when adjusting the tilt angle of the air outlet, requiring high-precision signal feedback to ensure real-time and effective dust suppression. This also brings challenges in areas such as increased maintenance difficulty, limited adaptability to different working conditions, and environmental protection.

[0005] Traditional tilt angle signal devices are typically mounted on one side of the fog cannon, transmitting signals via a rotating shaft and coupling. As a key component of the fog cannon, this device is constantly exposed to the outside of the equipment, making it susceptible to material impacts and dust intrusion, leading to frequent malfunctions, increasing maintenance complexity, and impacting dust suppression efficiency. Furthermore, the need for additional personnel for protective and maintenance work further increases operating costs.

[0006] Therefore, in view of the above situation, there is an urgent need to develop a key signal transmission device for intelligent fog cannons to overcome the shortcomings in current practical applications. Utility Model Content

[0007] The purpose of this invention is to provide a key signal transmission device for intelligent fog cannons, aiming to solve the problems mentioned in the background art.

[0008] This invention is implemented as follows: a key signal transmission device for an intelligent fog cannon includes a fog cannon body. A support is fixed to the top of the fog cannon body, and a wind tunnel is rotatably supported on the upper end of the support via a wind tunnel shaft. An air outlet is provided at the end of the wind tunnel. A hydraulic device for adjusting the tilt angle of the wind tunnel is also installed on the top of the fog cannon body. An inclinometer is installed on the wind tunnel shaft of the wind tunnel. A control device is provided inside the fog cannon body. The control device is electrically connected to the inclinometer through a signal transmission device on the wind tunnel. The control device is also electrically connected to the hydraulic device.

[0009] A further technical solution is that a protective cover is fixed to the outside of the inclinometer.

[0010] In a further technical solution, the inclinometer is fixed to the wind tunnel shaft by bolts.

[0011] In a further technical solution, the extension and retraction of the hydraulic device can cause the air outlet of the air duct to swing up and down.

[0012] The intelligent fog cannon key signal transmission device provided by this utility model has the following beneficial effects:

[0013] By directly fixing the inclinometer to the air duct shaft and adding a protective cover, the structure is compact and easy to install, requiring no external cooperation, simplifying the process and reducing labor costs. The use of a highly stable inclinometer enables precise signal transmission, reducing the number of parts and improving system stability and maintenance convenience. The device is integrated inside the fog cannon or in a concealed location, effectively preventing dust and impacts, extending its service life, and reducing maintenance frequency. Combined with a hydraulic control system, it enables remote automatic adjustment of the air outlet angle, forming a closed-loop control that adapts to complex working conditions and improves dust removal efficiency.

[0014] This device, while highly efficient in dust suppression, also boasts safety, economy, environmental friendliness, and ease of maintenance, making it a promising candidate for widespread application. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figure 1-4 As shown, an embodiment of this utility model provides a key signal transmission device for an intelligent fog cannon, including a fog cannon body 1. A support is fixed to the top of the fog cannon body 1, and a wind duct 5 is rotatably supported on the upper end of the support via a wind duct shaft 6. An air outlet 4 is provided at the end of the wind duct 5. A hydraulic device 9 for adjusting the tilt angle of the wind duct 5 is also installed on the top of the fog cannon body 1. An inclinometer 7 is also installed on the wind duct shaft 6 of the wind duct 5. A control device 2 is provided on the inner side of the fog cannon body 1. The control device 2 is electrically connected to the inclinometer 7 through a signal transmission device 3 on the wind duct 5. The control device 2 is also electrically connected to the hydraulic device 9.

[0023] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0024] Preferably, a protective cover 8 is fixed to the outside of the inclinometer 7 to provide safety protection.

[0025] In application, the control device 2 transmits signals to the hydraulic device 9. The hydraulic device 9 then extends and retracts according to the transmitted signals. This extension and retraction of the hydraulic device 9 causes the air outlet 4 of the air duct 5 to swing up and down. The swinging of the air outlet 4 thus performs dust suppression at different dust suppression heights. At the same time as the air outlet 4 swings, the corresponding air duct shaft 6 also rotates. An inclinometer 7 is located at the air duct shaft 6 and is secured with bolts, thereby causing the inclinometer 7 to rotate. The rotation of the inclinometer 7 is transmitted to the control device 2 via a cable. The control device 2 determines the appropriate position for dust suppression. A protective cover 8 is secured to the outside of the inclinometer 7 with bolts.

[0026] The above embodiments of this utility model provide a key signal transmission device for an intelligent fog cannon, which has significant advantages:

[0027] Firstly, by directly fixing the inclinometer 7 to the wind tunnel shaft 6 and adding a protective cover 8, the device achieves a compact structure and convenient installation. It eliminates the need for assembly with other external components, allows for independent control of overall installation accuracy, simplifies the manufacturing process, improves assembly efficiency, and reduces labor costs.

[0028] Secondly, the use of the inclinometer 7, which has high stability and does not require auxiliary accessories for signal transmission, makes signal transmission more accurate and reliable. At the same time, it reduces the number of parts, further compresses manufacturing costs, and improves the stability and ease of maintenance of the system.

[0029] Third, the signal transmission device is integrated inside the fog cannon or in a concealed location, effectively avoiding the risk of collision with external materials and dust intrusion. This not only extends the service life of the equipment but also greatly reduces the frequency and difficulty of daily maintenance, ensuring the long-term efficient operation of the equipment.

[0030] Fourth, the protective cover 8 has a simple structure and high processing precision, which not only improves the overall transmission efficiency, but also enhances the dustproof and protective capabilities of the device, ensuring stable signal transmission and safe and reliable operation.

[0031] Furthermore, the device automatically adjusts the air outlet 4 of the air duct 5 via remote control of the hydraulic device 9. Combined with feedback signals from the inclinometer 7, it forms a closed-loop control system, ensuring dust suppression under different working conditions and improving dust removal efficiency. The overall design incorporates intelligence, automation, and integration, adapting to complex and changing working environments and enhancing the mobility and ease of operation of the fog cannon.

[0032] In summary, this utility model not only achieves efficient and precise dust control, but also demonstrates multiple advantages in terms of safety, economy, environmental protection, and ease of maintenance, and has good application prospects and promotion value.
