Description

A safefy inspecting apparatus and the inspect method for fire fighting equipment

The present invention relates to a device and a method for checking the proper operation of the fire fighting equipment.

According to the Enforcement Decree of the Installation Maintenance and Safety Management Act of Fire Protection Facilities, firefighting objects that need to install sprinkler facilities must be provided with basement floors or windowless floors where the number of people is 100 or more and the floor used for movie theaters. Sprinklers are mandatory in places where the area of the stage is 300 m2 or more, where the stage area is more than 500 m2 and the other floors are 1,000 m2 or more. In the case of facilities or sales facilities, the building has three floors or less, and the floor area of sales and sales facilities is more than 6,000 square meters, and the building is four or more floors, and the sales and sales facilities have a floor area of more than 5,000 square meters. The place is required to have a sprinkler system installed.

In addition, apartment buildings with more than 11 floors, homeless facilities, or mental health facilities under Article 3 (2) of the Mental Health Act shall be a rack-type warehouse with a total floor area of 600m2 or more and a ceiling or half height exceeding 10m. The installation of sprinkler system is mandatory in the area of more than 1500m2.

However, even though the sprinkler is installed, it lacks a check means to check its normal operation even if the sprinkler is installed and analyzes the cause of why the sprinkler did not work after a fire event. It is today's reality that we are struggling.

The inventors of the present application are responsible for the safe management of the welfare spaces and facilities of residents, and manage the safety management of public offices and attached licensed facilities, youth welfare and sports facilities, etc. As a means to protect and improve the quality of life, the inspection and verification of fire-fighting facilities cannot be overemphasized. At present, the sprinkler head, a representative fire-extinguishing facility that extinguish fire by discharging extinguishing water in case of fire, Recognizes the problem of only checking the appearance visually because there is fear of damage caused by the discharge of extinguishing water, even if you want to do a normal operation test, and improves it by testing the opening function of the sprinkler head among the firefighting facilities. Check the operation of the facility to fulfill your responsibilities as a fire manager. The invention was started to secure the expertise as a snow manager.

On October 1, 2010, dozens of people were hospitalized in the 38th-floor high-rise apartment in Haeundae, Busan, due to asphyxiation and injuries. It took seven hours to run out, and it was shocked that the suppressor was not activated at all.

The fire authorities, embarrassed at the time of the fire, mobilized 52 meters of ultra-high ladders and various fire extinguishing trucks that reached the 15th floor but could not catch the fire that soared to the 38th floor by the ladder on the 15th floor. Although it was no longer burned inside, the losses and property damages caused by the large fires were enormous.

In 2008, a fire accident occurred in Icheon-si, Gyeonggi-do, which resulted in a serious casualty of 40 lives, resulting in 1,637 injuries and 120 deaths. The explosion occurred during this period of 1,279 people, of which 77 were killed.

Many fire-related incidents and accidents as described above can be reduced to 1/10 as a thorough preventive measure, and this company checks the device to check periodically whether the sprinkler that should be operated in case of fire accident is operating normally. The invention started with the problem to provide a, but the invention disclosed in the prior art with a problem similar to the present application was not found.

In addition, if you want to experiment to check whether the sprinkler works normally in a conventional building, water is sprayed from the sprinkler to prevent them from getting wet with the facilities, furniture, appliances, and flooring material inside the building. The inspection is skipped due to the complicated procedure of moving to and even if it is carried out after a thorough preparation process, if water spreads to the floor, it must be pumped out again and dried to make sure that the sprinkler works normally. Since it was a system, it was practically impossible to check the sprinkler while taking such an effort.

The headquarters is responsible for regular inspections of buildings with sprinklers in accordance with the Enforcement Decree of the Fire Fighting Facilities Installation and Safety Management Act, for example, once a quarter or once every half year. It is an invention that started the task of finding an inspection system to ensure fire prevention and safety management to protect people and property through means.

The present application is to provide a check device to check whether the sprinkler and related parts that must be operated in the event of a fire accident are operating normally. In this application, the thermal fuse of the sprinkler head installed on the ceiling of the office without any auxiliary means is used. To check whether the discharged water is discharged from the head, and at the same time, check the automatic fire extinguishing equipment (alarm valve pressure alarm, sprinkler operation alarm of the receiver, fire-fighting facility inspection of the repeater) Pressure check box function and spring cooler line charging auxiliary pump / main pump function check function) function can be checked without damage to indoor appliances and electric power using facilities by head discharge water. The present invention has an object to provide a check device to make.

The present invention is a device that can check whether the sprinkler and related equipment that should be operated in case of fire accident is operating normally, and has a check box formed with a space part to perform the heating process at the bottom position of the sprinkler, A heating means and a temperature sensor are built into the inspection enclosure, and a lower portion of the inspection enclosure is provided to have a drain portion. The heating heater is heated to a constant temperature to check whether the sprinkler and related equipment are normally operated. It has an inspection means, and it is a proper temperature to heat the heating heater to fuse the thermal fuse of the sprinkler head. The sensing temperature at the moment when the sensor bursts the discharge water can be interpreted as a constant temperature.

If the sprinkler is sprinkled by the normal operation of the sprinkler, the sprinkling water is measured through the measuring part of the drainage part and the water meter-like structure, and the amount of water is measured by draining or flowing into the water tank to determine the adequacy. It will be used as.

In addition, it is also preferable that the wheel is installed to move the check box to one side so that the upper end of the check box is located directly below the sprinkler, and the lifting box is moved up and down, and to place the check box directly under the sprinkler cooler type Or a moving means such as a means for rotating the screw shaft using a motor, and the fire fighting system inspection apparatus of the present application includes a control box for adjusting / controlling a heating means and a temperature sensing sensor inside the inspection box.
