Description
Technical Field
[0001] The utility model belongs to the technical field of fire protection, and specifically relates to an airtightness detection device for fire protection facilities. Background Technique
[0002] The core of fire protection work includes the emergency rescue of personnel at the fire scene, the rescue of key facilities and cultural relics, the safety guarantee and rescue of important assets, and the extinguishment of fires, aiming to minimize the damage caused by fires and reduce casualties and property losses. In modern buildings, a series of fire protection facilities are usually equipped to play an important role in the event of a fire and effectively reduce the material losses caused by the fire.
[0003] The fire hose is an important part of these facilities. To ensure that the fire hose can work properly in an emergency, it must be regularly tested for airtightness. During the test, the fire hose is usually placed in a container filled with water, and then inflated inside the fire hose, and carefully observed for air leakage. However, due to the long length of the fire hose, when fully unfolded, it will occupy a relatively large space, which also poses certain challenges to the detection work. For this reason, we propose an airtightness detection device for fire protection facilities. Content of the Utility Model
[0004] In order to solve the problem that currently the fire hose is usually placed in a container filled with water, inflated inside the fire hose, and carefully observed for air leakage, which will occupy a relatively large space and also pose certain challenges to the detection work, the utility model provides the following technical solution: an airtightness detection device for fire protection facilities, including a bottom plate, on both sides of the upper wall of the bottom plate, fixing rods are respectively arranged, a rotating shaft is arranged on the two fixing rods, rotating disks are arranged on the two rotating shafts, an elevation frame is arranged on the upper wall of the bottom plate, a sealing box is arranged on the elevation frame, a vacuum machine is arranged on the top of the sealing box, a barometric pressure detector is arranged inside the sealing box, a control panel is arranged on the side wall of the sealing box, a buzzer is arranged on the control panel, the control panel, the barometric pressure detector and the vacuum machine are electrically connected, through holes are respectively opened on both sides of the sealing box, lifting doors are respectively arranged on the two through holes, air cylinders are respectively arranged on both sides of the sealing box, the telescopic ends of the two air cylinders are respectively connected to the top of the lifting doors, and a sealing structure is arranged at the bottom of the lifting doors.
[0005] Preferably, the sealing box is made of a transparent material, enabling the operator to directly observe the detection process.
[0006] Preferably, the two rotating disks are symmetrically designed, and grooves are provided in the middle of the two rotating disks for fixing the fire hose to ensure stability during detection.
[0007] Preferably, the sealing structure includes an airbag. An air pump is provided at the top of the sealing box, and the air pump is connected to the airbag through an air charging pipe to ensure the sealing performance.
[0008] Preferably, the sealing structure is a gasket, and the gasket is made of rubber, silica gel, nylon cloth or Hypalon tape.
[0009] Preferably, a motor is provided on the upper wall of the bottom plate. A gear is installed at the output end of the motor, and the gear is connected to a rotating shaft on one side through a chain drive to drive the rotating disk and the fire hose thereon to rotate, facilitating all-round detection.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] During operation, first place the fire hose to be detected on the rotating disk, control the cylinder to raise the lifting door, open the through holes on both sides, pull out one end of the fire hose, pass it through the sealing box, and place it on the rotating disk on the other side. After placement, control the cylinder to act in the reverse direction to lower the lifting door and close the through holes of the sealing box. Control the air pump to fill the airbag with air to form a sealed space. The operator starts the vacuum machine on the control panel to extract the air in the sealing box, creating a negative pressure environment inside the box. The air pressure detector will monitor the air pressure change in the sealing box in real time and transmit the data to the control panel for display and analysis. After receiving abnormal data, the control panel will trigger the buzzer to sound an alarm. After the detection is completed, the lifting door is opened.
