Description

Technical Field

[0001] The utility model belongs to the field of fog piles, and specifically relates to a folding rod and a folding fog pile system. Background Art

[0002] In order to solve the problem of high-altitude dust in municipal roads, construction sites, ports, open-pit mines, and enterprise parks, washing and sweeping vehicles, watering vehicles, vehicle-mounted fog cannons, fog piles and other equipment are generally used for dust suppression. Washing and sweeping vehicles, watering vehicles, vehicle-mounted fog cannons and other equipment have small operating areas, large spray droplets, and frequent maneuvers, which aggravate traffic congestion. In addition, the conventional one-time investment is large and the maintenance and use costs are high. Furthermore, many cities install high-pressure spraying facilities, namely conventional fog piles, on congested sections during morning and evening peaks to reduce road dust and vehicle nitrogen oxide emissions. High-pressure spraying facilities are installed on roads congested during morning and evening peaks in various urban areas. The forms include but are not limited to 360° rotating poles and L-pole and T-pole high-pressure micro-fog systems. An operating platform is built to use the concentration of nitrogen oxides and particulate matter, as well as temperature, sunny and rainy weather and other meteorological conditions as conditions for intelligent opening of the spraying facilities, and to realize the intelligent management and intelligent control of the platform, which is green and energy-saving. Obviously, the use of 360° rotating fog piles with poles will become more and more widespread.

[0003] Mist piles are usually composed of pile poles, host machines, electronic control systems, rotary spray heads, pipe systems, nozzles, etc. Mist piles use high-pressure water jet technology to pressurize water to 5-7Mpa or higher through the host water pump, and then transport the water to the rotary spray head installed on the pile pole through the pipe system, and spray it out through the high-pressure atomizing nozzle on the head.

[0004] In the control of high-altitude dust, traditional fog piles are limited by the height of the installation pile and the convenience of transportation. The rotary spray head is generally installed on the piles with concrete foundations on the sides of municipal roads or in the middle of flower beds, or on the horizontal ground of industrial and mining enterprise parks. The piles are generally controlled within 10 meters and use a whole single-section fixed-length steel structure rod or a multi-section welded fixed-length steel structure rod. During installation and construction, large-scale lifting equipment is often required for hoisting operations due to the long length of the piles. The high construction cost also brings the corresponding risk of high-height hoisting operations.

[0005] At the same time, the rotary spray head generally uses a servo motor or a stepper motor as the power component for the rotation of the head. However, the rotary spray head installed on a fixed height pile pole often stops rotating for repair because the drive motor connection line is entangled closely with the hose and the vibration causes the line to loosen. Furthermore, during the long-term reciprocating rotation of the rotary head, it is inevitable that the joints of the pipes will loosen and leak water. At this time, the drive motor wiring is very susceptible to moisture and short circuit failure. Regardless of the fault of the rotary head, it needs to be repaired at high altitude or hoisted and laid down by large lifting equipment for maintenance. At this time, the maintenance of the aerial work vehicle and the lifting equipment occupies a large construction site, blocking traffic, and greatly increasing the safety risks and costs of fog pile operation and maintenance. In addition, although there are foldable poles that can be folded, the hinge structure of the folding pole is fragile and has a short service life, which makes it difficult to meet the application scenarios of fog piles that require long-term use.

[0046] As attached Figure 1 -Attached Figure 7As shown, the utility model provides a folding rod, including a lower pile rod 4 and an upper pile rod 5, wherein the lower end of the upper pile rod 5 is provided with an arc-shaped support plate 16 extending axially along the upper pile rod 5, and the arc-shaped support plate 16 is preferably a semicircular structure or a inferior arc structure, and when the lower pile rod 4 and the upper pile rod 5 are upright at 180°, the arc-shaped support plate 16 fits the outer wall of the lower pile rod 4 and limits the position, so that the angle between the lower pile rod 4 and the upper pile rod 5 cannot be greater than 180°;

[0047] The lower end of the upper pile rod 5 is provided with an upper ear plate 10 protruding outward, and also includes two hinged ear plates 15 relatively arranged on the upper pile rod 5, the upper end of the hinged ear plate 15 is fixed on the upper ear plate 10, and the side of the hinged ear plate 15 is fixed on the arc-shaped support plate 16. On the one hand, the hinged ear plate 15 is connected to the upper pile rod 5 through the upper ear plate 10 and the arc-shaped support plate 16, which can greatly improve the structural strength and stability of the hinged ear plate 15, and then improve the strength and stability of the hinged structure. On the other hand, the hinged ear plate 15 also serves as a reinforcing rib structure of the arc-shaped support plate 16, which can improve the structural strength of the arc-shaped support plate 16 and avoid deformation of the arc-shaped support plate 16. Therefore, the above arrangement not only improves the strength of the hinged structure, but also increases the structural strength of the arc-shaped support plate 16;

[0055] The inner wall of the arc plate 23 is fitted with an arc reinforcing plate 11, thereby improving the structural strength of the shaft fixing block 14 and the structural strength of the hinge structure.

[0056] In one of the embodiments, two self-lubricating graphite copper sleeves 20 are embedded at both ends of the rotating shaft fixing block 14 to achieve a perfect hinge structure and ensure the stability and smoothness of the rod body during folding and rotating movements.

[0057] In one of the embodiments, at least one annular reinforcing plate 12 is disposed on the inner wall of the upper end of the lower pile rod 4 , thereby improving the structural strength of the rotating shaft fixing block 14 of the lower pile rod 4 .

Preferably, the main unit 1 is provided with a three-stage pre-filter of water inlet PP cotton + compressed carbon + folded filter element, and a high-pressure purification filter is also provided at the water outlet. The above configuration can ensure that the main unit 1 stably provides high-pressure filtered water to ensure the dust reduction effect of the fog pile; a rain and snow sensor is provided in the main unit 1, which automatically senses rain and snow and instructs the linkage main unit 1 to shut down, thereby achieving energy saving and consumption reduction.

[0068] The utility model has the following beneficial effects by combining the fog pile system with the folding rod:

[0069] 1. The split design adopted mainly divides the pile rod into two parts, the length of a single rod body is reduced, and transportation is easy. During installation, the upper pile rod 5 and the lower pile rod 4 can be erected after the pin 13 is installed in the hinged part of the folded state. There is no need for high-altitude lifting operation when erecting the pole in the folded state. The assembly and installation are convenient and easy, which effectively protects the safety of operators.

[0070] 2. When the sprinkler head and the water pipe 19 need to be inspected, the present solution can release the upright locking device, and adjust the angle of the upper pile rod 5 by adjusting the rope, so that the upper pile rod 5 can be rotated around the pin shaft 13 to a suitable inspection height from the ground.

[0077] The specific working principle of this utility model:

[0078] When the foldable fog pile system is working, the electronic control system 2 gives instructions, and the water pump motor in the main unit 1 starts according to the instructions. The main unit 1 draws water from the water intake point of the main water supply pipeline, pressurizes it through the internal water pump motor, and then sends the pressurized water to the nozzle installed at the upper end of the installation sleeve 7 through the pipeline system 3 and the water pipe 19 for spraying.

[0079] When the foldable fog pile system works normally, the upright locking device locks the upper pile rod 5 upright on the lower pile rod 4.

[0080] When the foldable fog pile system fails, unlock the upright locking device, tie a section of the adjusting rope to the hole on the fixed ear plate 17, pass it through the buckle port 22 and put it in the operator's hand, pull the upper pile rod 5, and gently release the rope. At this time, the nozzle, the installation sleeve 7 and the upper pile rod 5 rotate around the pin shaft 13 to a suitable maintenance height from the ground. The water pipe 19 and other pipelines in the pile body are adaptively bent as the rotation angle increases. The equipment and facilities on the top of the upper pile rod 5 are lowered as the rotation occurs, so that the maintenance personnel can touch the nozzle and water pipe 19 on the top of the upper pile rod 5 on the ground for maintenance.

[0081] The above is only an embodiment and does not limit the present invention in any way. Any person skilled in the art can make many possible changes, modifications or modifications to the present invention without departing from the scope of the present invention by using the above disclosed technical contents. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the present invention should fall within the scope of protection of the present invention.
