Description

Security apparatus for water canon

The present invention relates to a fire protection waterproof gun safety interception device, and more particularly, is applied to a fire fighting water gun coupled to a cradle and a cradle used at a fire site for fire fighting, so that the fire fighting water gun coupled to the cradle conducts (顚倒) When it is fired, the firefighting water that is fired from the firefighting water gun is temporarily blocked to prevent safety accidents that may occur due to the firefighting water gun that is fired and the firefighting water that is fired at high pressure. It relates to a fire-proof waterproof gun safety barrier device for improving the safety of the waterproof gun.

The waterproof fire fighting gun is a device that discharges high-pressure fire-fighting water from a fire site.

At this time, the pressure of the waterproof nozzle connected to the fire engine is usually about 0.7 [MPa], which is a pressure that can withstand about 20 [minutes] with the stamina of a firefighter 1 [person], but the pressure of the waterproof nozzle when the high pressure waterproof is 1.4 [ MPa] or higher, making it difficult to withstand 2 [people] firefighters.

In addition, the waterproof gun for fire fighting may cause another safety accident due to the pressure of the fire fighting water delivered through the fire hose.

In other words, due to various factors (malfunction of the waterproof pressure of the fire engine, twisting of the hose, etc.), pressure fluctuations or vortices of the fire fighting water are generated, and the fire fighting water gun is released from the gripping hand of the firefighter, causing the fire fighting water gun to fluctuate. It can also cause other safety accidents other than fire.

More specifically, the fire-fighting water gun is a device that discharges high-pressure fire-fighting water from a fire site, etc., but it is the most essential equipment to be held and manipulated by firefighters. It is impossible to grasp, and there is a danger that secondary safety accidents may occur due to waterproof pressure.

The secondary safety accident due to the waterproof pressure, for example, as described above, the fire hose connected to the waterproof gun for fire fighting, due to various factors (waterproof pressure malfunction of the fire engine, hose twisting, etc.) A vortex is generated, which refers to a secondary safety accident that may increase or decrease the power of the fire-fighting water gun that was held, hinder and deteriorate the role of firefighters, and escape the fire-fighting water gun.

That is, the departure of the fire fighting water gun causes another fatal safety accident due to the fluctuation of the fire fighting water gun, such as price and damage of the face part and surrounding structures of a firefighter or people in an urgent fire scene.

In addition, there are many combustibles in warehouse-type shops or industrial sites of mass production systems, so the extinguishing time often lasts more than 1 [hours]. At this time, firefighters fighting fire can not maintain waterproof for a long time due to the pressure of the waterproof nozzle. At the same time as the situation occurs, when waterproofing, firefighters 2 [persons] to 3 [persons] must always support the water gun and distribute power, causing a problem that unnecessary manpower is lost.

In order to solve such a conventional problem (a problem caused by the waterproof pressure of a fire fighting water gun), various fire fighting water guns and fire fighting robots have been developed and deployed in the field, but the effect of improving the waterproof distance or the density of the fire fighting water is improved. The fire-fighting robot is being developed and focused on the problem that rapid movement is impossible with a weight of about 1.5 [tons], and it is difficult to be practically applied since it is directly deployed to the site because it is an equipment manufactured at a high cost. Problems, such as technology to solve the original problems such as ease of operation, portability, etc. of fire fighting water gun, but the situation is insufficient to respond to this.

Therefore, there is no discomfort for firefighters and site managers who can immediately firefighters who have to be put into the fire site without accidentally putting a lot of effort on high-pressure waterproofing for a long time, and finally, anyone can easily use them at the fire site. In addition to the new fire-fighting gun configured to be constructed, a cradle capable of easily mounting it must be developed.

However, the development of these new fire-fighting water guns and their combined cradles may also be difficult to address all of the factors of secondary safety accidents that may be caused by fire-fighting water guns at fire sites exposed to various hazards. have.

Therefore, the present invention solves all of the factors of secondary safety accidents that may occur due to fire-fighting water guns and high-pressure fire-fighting water guns other than fire, which are unexpected in such a fire site, and more stable and safe fire-fighting waterproofing It was invented to provide a gun.

Subsequently, the firefighter operates the manual switching member portion 240 of the second blocking means 200 (releases the lock), operates the fire-fighting blocking member portion 220, and engages the third locking member 231. The locking operation member 321 of the blocking means 300 is separated, so that the ball valve member 311 located inside the fireproof water gun WC is instantaneously rotated, and immediately blocks the foaming path of the fire fighting water for fire fighting. Fire water from the water gun (WC) should be blocked.

On the other hand, the present invention fire safety water gun safety interception device (1) is coupled to the cradle (10) on which the fire fighting water gun (WC) and the fire fighting water gun (WC) are mounted, in particular, the support leg (11) of the cradle (10) On one side, among the components of the first blocking means 100, a moving range securing hole (LH) having a predetermined length may be formed so that the heavy object sensing unit 120 is easily coupled.

That is, according to the movement of the heavy object movement detection bracket 121 coupled to the heavy object movement detection transfer member 114, the heavy object 111, the movement range ensuring hole (LH) to move without friction within a limited range It can be formed.

For reference, the term'object' used in describing the present invention is

It is defined as an object whose mobility is created by obstacles, people, and the natural environment in the fire site.

In addition, Figure 5 (a) shows a state in which the engaging operation handle member 321 is coupled to the engaging member 231, that is, a state in which fire fighting water is foamed,

FIG. 5(b) shows a state in which the engaging operation handle member 321 is separated from the engaging member 231, that is, the foaming of the fire fighting water is blocked.

In addition, looking briefly at the operating subject of the present invention fire safety gun safety shut-off device (1),

The first blocking means 100 is naturally operated by gravity,

The second blocking means 200 may be operated by a firefighter or by the first blocking means 100,

The third blocking means 300, the coupling with the second blocking means 200 is necessarily made by the firefighter, but the separation from the combined second blocking means 200 by the firefighter or the first blocking means (100) ) Can be separated by being operated by the second blocking means 200.

In addition, the character described in'[ ]'is a unit, and is for easily distinguishing between a character (number) and a unit.
