Large buildings over a certain number of floors with lots of people are obliged to install sprinkler heads (hereinafter, mixed with heads) for early detection and automatic evolution of fire. Of course, as fire safety awareness is raised, it is a good idea that building owners who value the lives and property of the people themselves install sprinkler heads in low-rise buildings themselves.
The sprinkler head is divided into a closed type and an open type depending on the presence or absence of a thermal part (fuse, soluble piece). The open type has a structure in which a head is not provided with a thermal head, and the closed type has a thermal head in a head.

The sprinkler head is divided into a dry type, a preparation type and a wet type depending on whether or not the piping is filled with fire water. The dry type is a structure in which no fire water is filled in the piping, A pre-action valve is installed at a certain point of the pipe, and the valve is connected to the first pipe at a certain point of the pipe, When the fire is detected in the head and the fire-fighting water injection signal is received, the pre-action valve (not shown) connected to the primary side is connected to the primary side, The pre-action valve is opened through the process of reconfirming by In the case of wet type, pressurized fire water always exists in the whole piping, so that the fire water shutoff part is dismantled according to the sensed signal of the thermal part, and the fire water is sprayed through the spray part and sprayed widely in the fire area, As shown in Fig.

Therefore, a closed type wet type sprinkler head is provided with a pipe for supplying fire-fighting water for fire extinguishing from the water source to the ceiling of each room of the building. The water is sprayed automatically by sensing the fire at the end of the pipe, A sprinkler head installed to be installed. Thus, it should be understood that the term "sprinkler head" or "head" is hereinafter referred to as a "closed wet sprinkler head".

Reference is made to "Prior Art Documents 1 to 7" given below. A general "closed type wet sprinkler head" is composed of a frame portion, a heat conducting portion and a jetting portion, and is piped from the water source to the top of the ceiling, Quot; is a sprinkler head that is coupled to an end of each branch tube and is installed to be projected into a room.

The sprinkler head is connected to each branch of the piping. The sprinkler head is designed to have various structures such that the thermal-insulating member and the spraying member block the fire-fighting water discharge port. When a fire occurs, the thermal- And spraying the pressurized fire water to a wide range of the fire area through the injection part, thereby automatically suppressing the fire.
In recent years, an advanced sprinkler head which is not separately divided into a thermal part and a spray part has been introduced, but the basic principle of the sprinkler head follows the well-known concept of principle as described above.

However, in order to suppress the fire by spraying the fire water in a wide range of the fire area, it is very useful to install the sprinkler head so as to protrude by a predetermined length toward the room. This is to ensure an efficient downward spray angle of the fire water so that the fire water can be sprayed over a wide range of the fire area.

On the other hand, in a place where an impact may be applied to the ceiling, such as an indoor golf practice room that is opened in a building having a predetermined number of layers or more, a ceiling is protected from impact by attaching a shock absorber 5 centimeters thick.

However, due to the burden on the installation cost of the shock absorber, some of the building owners have the risk of damaging the ceiling due to the impact because they install the sprinkler head directly on the ceiling finishing material without attaching the shock absorber to the ceiling finishing material. In addition, a large number of sprinkler heads protruding from the ceiling finishing material toward the inside of the room for a predetermined length are frequently damaged by shocks due to strong exercise hitting by the users, so that the pressurized fire water having a predetermined pressure inside the piping is undesirably There is a possibility that the installation angle of the sprinkler head is changed due to the impact and the installation direction of the head heat conducting part (fuse) is shifted. In case of fire, The sprinkler It often happens that the function of the head is lost.

Therefore, it is possible to prevent breakage due to the impact even when hit by a practicing batting practice of the indoor golf driving range users, and furthermore, it is possible to prevent the change of the installation angle of the head, There is a strong demand for a closed type wet type sprinkler head having an impact damage preventing structure which is configured to be compatible with other existing sprinkler heads for protecting the head.

10, the head protector 500 includes an upper ring 510 formed of an iron material and having a ring shape having a central opening and having a nut body 512 formed on an inner diameter thereof, A lower ring 520 formed of an outer diameter smaller than the outer diameter of the upper ring 510 and having a central opening and a lower ring 520 formed by a steel piece having a predetermined length and having an upper end welded to the outer diameter portion of the upper ring 510, A predetermined number of hinges 530 welded to the outer diameter portion of the shock absorbing member 520 are integrally formed by welding and the upper ring 510 is fixed to the frame 100 to the outside of the lower end of the protector coupling portion 150 of the lower body 100b.

A nut body 512 is formed on the inner diameter of the upper ring 510.

Since the width of the upper ring 510 is larger than the thickness of the lower ring 520 because the width of the nut 512 of the inner diameter of the upper ring 510 is increased, Can be increased.

The inner diameter of the lower ring 520 is formed to be equal to or larger than the inner diameter of the protector coupling unit 150 so that the thermal function of the thermal interface unit 2 is not disturbed.

Since the lower ring 520 formed as described above can directly sense the heat from the lower portion of the thermal head 2 without being disturbed by the inner diameter, the thermal head 2 can be accurately sensed.

It is preferable that the predetermined number of hinges 530 is 3 to 4 so as not to affect the downflow angle of the fire water. When the number of the hinges 530 is less than 2, there is a problem in balancing and the head protection can be neglected. If the number of the hinges 530 is 5 or more, it may interfere with the jetting of the fire water.

The head protector 500 may be formed in such a manner that the upper ring 510 is screwed to the outside of the lower end of the protector coupling portion 150 of the lower body 100b of the frame 100 protruding from the passages 310 of the impact receiving member 400, Respectively.

A plurality of piece coupling holes 511 may be formed in the top ring 510 along the ring shape so that the head protector 500 can be coupled to another sprinkler head installed in the ceiling finishing material C .

Therefore, the head protection member 500 can be used in combination with other installed sprinkler heads.

The thermosensitive part 2 and the jet part 3 are housed in the lower part 100b of the frame 100. The ends of the thermosensitive part 2 and the jet part 3 are connected to the frame lower part 100b The head protector 500 is positioned on the inner diameter side of the lower ring 520 when the golf ball is inserted into the inner diameter of the lower ring 520 from a lower portion of the lower ring 520, And the upper end of the protrusion of the golf ball protruding from the ejection portion 2 and the ejection portion 3 are separated from each other by a predetermined distance.

The predetermined spacing distance may be adjusted by adjusting the degree of thread engagement of the head protector 500 coupled to the outside of the lower end of the protector coupling portion 150 of the lower body 100b of the frame 100. [

The predetermined spacing distance may be adjusted according to the degree of elasticity of the impact receiving member 300.

Next, the operation of the closed type wet sprinkler head (A) having the shock-resistant damper of the present invention will be described in detail.

First, a pipe for supplying fire-fighting water for fire extinguishing is installed from the water source to the ceiling of each building.
