Multifunctional tow tong structures {Multifunctional tow tongs}

The present invention relates to a multi-functional towing tong structure.

Specifically, it relates to a multi-functional towing tong structure that can hold and support a fire hose used for fire suppression and prevent the fire hose in a long direction from sagging.

In addition, the multi-functional towing tong structure according to the present invention relates to a multi-functional towing tong structure configured to adjust the length of a support pipe supporting a fire hose according to the load and length of the supporting fire hose.

Most of the territory of the Republic of Korea consists of mountains.

Although these mountains are spectacular, they are very difficult to manage.

In particular, it is very vulnerable to fire. Recently, in Korea, there is a history of large-scale forest fires occurring in Gangwon-do in 2019, covering the Goseong, Sokcho, Gangneung, Donghae, and Inje areas. In addition to these large-scale forest fires, large and small forest fires frequently occur. This is the situation.

When such a forest fire occurs, fire trucks as well as fire helicopters are dispatched to extinguish the fire. In the case of a forest fire, the range is very wide, so even if the fire is extinguished using water supplied primarily, it takes time to recharge the supplied water. The fire is spreading again due to the wind, making it difficult to extinguish.

Accordingly, the present applicant came up with a fire management technology that could utilize acid.

Among the prior technologies applied for by the present applicant, Publication Patent Publication No. 10-2010-0120021 describes a forest fire extinguishing and water management system.

The above technology relates to a forest fire extinguishing and water management system. More specifically, a stepped weir is created using water generated in a valley, and a water tank is installed underground of the weir to store water and supply it when needed or A forest fire extinguishing and water management system that extinguishes forest fires and performs water management systematically by supplying and storing water stored in a water tank installed on the back and then using it to extinguish forest fires during dry periods or when forest fires occur. It's about.

To elaborate, beams 11 installed at each location upstream, middle, and downstream of the valley 10; An underground water tank (13) installed underground of the weir (11) and forming an inlet (14) where water overflowing the weir (11) is stored; It consists of a water tank (20) connected to the underground water tank (13), a water supply pump (17), and a water supply pipe (19), installed on the summit or ridge (25), and connected to a nozzle pipe (21). It is a feature.

In addition, with regard to forest fire suppression, Publication Patent Publication No. 10-2008-0025706 describes unmanned forest fire extinguishing automated device facilities and structures.

The above technology is to build a fixed structure in a rugged mountain area in a forest fire-prone area in a protected forest area and install a forest fire extinguishing automation device (automated fire extinguishing system computer, functional surveillance camera, satellite communication device, wind pressure anemometer, automatic spray control pipe, water tank (water tank), water pressure). Pressure device, receiver, power generator, motor pump, alternative energy electric device (solar power electricity, wind electricity), D/C A/C conversion inverter, automatic control box, rainwater purification device, fire protection device) are constructed and installed on a fixed structure. It relates to unmanned, automated forest fire extinguishing equipment facilities and structures that monitor forest fires and forest damage, detect forest fires at an early stage, and quickly extinguish them.

Additionally, Publication Patent Publication No. 10-2022-0064847 describes a rainbow green sumac principle piping system.

In the above technology, water cannot be discharged to the bottom of the currently installed dam reservoir and water is discharged to the middle and upper part of the reservoir. As a result, miscellaneous fallen leaves, weeds, and numerous foreign substances that float down with rainwater during the rainy season from the upper part of the reservoir float down to the sea as the dam blocks it. As pollutants generated by rotting water accumulate and accumulate as sediment that cannot float away and hover in the reservoir field, the concentration of pollutants in the reservoirs increases every year, and the reservoirs are covered with a dark blue color that makes the bottoms of the reservoirs invisible. If water pipes are installed according to the water vein principle, water is extracted from the bottom of the reservoir and discharged, thereby solving problems that occur in the reservoir. In addition, as specified in the specifications, water is extracted and discharged from the bottom of the reservoir for storage management, and a fishway is installed on the dam embankment to drain the reservoir. In the area below, reservoir water can be used as water for agricultural and fisheries industries, and clear spring water at the bottom of the reservoir can be used as water supply. It is a piping system based on the water vein principle that can reduce damage from forest fires by preventing damage from rainwater.

Meanwhile, forest fires do not occur only in specific locations, but occur and spread irregularly in random spaces.

Accordingly, in addition to a fixed water supply means, a technology that can extinguish a fire at any location is needed.

In addition, the same applies to all fires in general, but in the case of forest fires in particular, the surrounding area is made up of plants that are easily flammable, so even a small ember can spread quickly. In addition, since forest fires are exposed to nature, they spread more easily due to wind and embers move frequently.

In these situations, a fire is likely to spread quickly even in the small amount of time it takes to continuously replenish water.

Technical means to prevent the spread of such fires are also needed.

In addition, in relation to the above-described hose, the present applicant has applied for a multi-functional fire hose under Application No. 10-2022-0076895.

Supporting technology that can be used to support these fire hoses is also needed.

For the purpose of supporting a fire hose, a tripod for supporting a fire hose is described in Registered Patent Publication No. 10-2219605.

The above technology connects the fire hose and the pipe nozzle and supports them at a certain height from the ground. In addition, the support height of the fire hose and the spray angle of the pipe nozzle can be easily adjusted, and when the fire hose sprays water, the fire hose's This relates to a tripod for supporting a fire hose whose structure has been improved to prevent shaking.

However, the prior art, including the above-described technology, has a problem in that it is not suitable for purposes such as supporting fire hoses in large-scale fires such as forest fires.

In addition, technology that can support or move the above-mentioned fire hose is needed.

Public Patent Publication No. 10-2010-0120021 (2010.11.12.) Public Patent Publication No. 10-2008-0025706 (2008.03.21.) Public Patent Publication No. 10-2022-0064847 (May 19, 2022) Registered Patent Publication No. 10-2219605 (announced on February 23, 2021)
