Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting facility detection, in particular to air-tightness detection equipment for fire-fighting facilities. Background Art

[0002] Firefighting facilities refer to fixed facilities such as automatic fire alarm systems, indoor fire hydrants, and outdoor fire hydrants in buildings. Fire extinguishers are a common tool in firefighting facilities. The production of fire extinguisher tanks usually requires the following processes: tank body rolling, longitudinal seam welding, upper and lower heads, and tank valve seat welding. After the prototype of the tank is produced, in order to ensure product quality and later use, the tank body's welds must generally be tested for airtightness to detect whether there is any leakage in the welds.

[0003] For example, Chinese patent publication number CN214702669U discloses an air tightness detection device for fire-fighting facilities, including a workbench, bases are fixedly installed on both sides of the bottom of the workbench, a mounting plate is fixedly installed between the two bases, an air pump is fixedly installed at the middle position of the top of the mounting plate, two placing tables are fixedly installed on the top of the mounting plate, fixing rods are fixedly installed on the four ends of the top of the mounting plate, a top plate is fixedly installed on the top of the mounting plate through the four fixing rods, a cylinder is fixedly installed at the middle position of the top of the top plate, the output end of the cylinder passes through the top plate and extends to the bottom of the top plate, and a movable plate is fixedly installed on the output end of the cylinder. The utility model sets a series of structures to make the device convenient for air tightness detection of the fire extinguisher tank body, can reduce the generation of detection errors, and compared with the water bath method, will not leave a large amount of moisture on the surface of the tank body, which is convenient for subsequent processing of the tank body.

[0004] The existing technology has the following problems:

[0005] Before conducting the test, the detection equipment needs to exhaust the gas in the closed hood through an air pump. During the process of exhausting the gas, the fire extinguisher tank is still leaking, which makes it difficult to determine a control point to stop the air pump to ensure that the gas in the closed hood is the gas in the fire extinguisher tank, rather than the original gas in the closed hood. At the same time, there are too many pipe connections between the closed hood and the air pump, which may cause leakage and lead to detection errors. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 , Figure 2 As shown, a fire-fighting facility air tightness detection equipment includes a water tank 1, the upper surface of the water tank 1 is fixedly connected to a top plate 2 through a column, the left and right walls of the water tank 1 are rotatably connected with four first screw rods 3 distributed in a rectangular manner, the left and right walls of the water tank 1 are rotatably connected with four second screw rods 4 distributed in a rectangular manner, and the second screw rod 4 is located between the front and rear of the four first screw rods 3, the upper side of the first screw rod 3 is fixedly connected with a first power mechanism 5, the lower side of the first power mechanism 5 is fixedly connected to the upper surface of the top plate 2, the upper side of the second screw rod 4 is fixedly connected with a second power mechanism 6, the lower side of the second power mechanism 6 is fixedly connected to the upper surface of the top plate 2, the right side of the water tank 1 near the bottom is fixedly connected with a water outlet pipe 7, the outer wall of the first screw rod 3 is threadedly connected with a placing mechanism 8, and the outer wall of the second screw rod 4 is threadedly connected with an isolation mechanism 9.

[0028] It should be noted that there are components such as gears and motors in the first power mechanism 5 and the second power mechanism 6. The first power mechanism 5 can drive the four first screw rods 3 to rotate synchronously, and the second power mechanism 6 can drive the four second screw rods 4 to rotate synchronously. The threads on the first screw rods 3 and the second screw rods 4 are completely consistent.

[0029] like Figure 2 , Figure 3 As shown, the placement mechanism 8 includes a first pull rod 81, the inner side of the first pull rod 81 is threadedly connected to the outer wall of the first screw rod 3, and there are four first pull rods 81 distributed in a rectangular shape. The lower side of the first pull rod 81 is fixedly connected to a fixing frame 82, and the inner side of the fixing frame 82 is movably sleeved with a first placement frame 83.

[0030] It should be noted that when the first screw rod 3 rotates, the first pull rod 81 moves up and down along the first screw rod 3, thereby driving the fixing frame 82 to move up and down, and further driving the first placement frame 83 to move up and down.

[0031] like Figure 3 , Figure 4 As shown, a plurality of evenly distributed placement platforms 84 are fixedly connected to the upper surface of the first placement rack 83 , a plurality of placement platforms 84 are provided with slots 85 on their upper surfaces, and a plurality of rubber rings 86 are fixedly connected to the inner and outer surfaces of the slots 85 .

[0032] It should be noted that the first placement rack 83 is used to place the fire extinguisher tank to be tested, the card slot 85 is used to place the lower edge of the isolation cover 93, and the rubber ring 86 fits the outer wall of the isolation cover 93 near the bottom to achieve the purpose of sealing and avoid water leakage.

[0033] like Figure 2 , Figure 5 As shown, the outer wall of the first screw rod 3 is threadedly connected with a lifting assembly 87, and the lifting assembly 87 includes a movable seat 871, the inner side of the movable seat 871 is threadedly connected to the outer wall of the first screw rod 3, and there are four movable seats 871 distributed in a rectangular shape, and the movable seats 871 are fixedly connected with cross fixing frames 872 at positions close to each other on the side away from the water tank 1, and there are two cross fixing frames 872 symmetrically distributed on the left and right, and the lower end of the cross fixing frame 872 is fixedly connected with two placement plates 873 symmetrically distributed front and back, and the placement plates 873 are located on the front and back sides of the water tank 1, and the left and right sides of the two placement plates 873 are fixedly connected with second pull rods 874 near the front side, and the upper end of the second pull rod 874 is fixedly connected to the side of the movable seat 871 on the same side away from the water tank 1.

[0034] It should be noted that when the first screw rod 3 rotates, it drives the movable seat 871 to move up and down. When the movable seat 871 moves, it drives the cross fixing frame 872 to move up and down, and then drives the placement plate 873 to move up and down. The second pull rod 874 is used to support the placement plate 873 away from one side of the water tank 1 so that the front and rear sides of the placement plate 873 are evenly stressed.

[0035] like Figure 1 , Figure 5 As shown, the bosses on one side of the placement plate 873 that are close to each other are slidably connected in the vertical grooves on the front and rear sides of the water tank 1.

[0036] It should be noted that the boss is slidably connected in the vertical groove, so that the side of the placement plate 873 close to the water tank 1 is supported, thereby reducing the friction between the placement plate 873 and the water tank 1.

[0037] like Figure 2 , Figure 6As shown, the isolation mechanism 9 includes a third pull rod 91, the inner side of the third pull rod 91 is rotatably connected to the outer wall of the second screw rod 4, and four third pull rods 91 are distributed in a rectangular shape, the lower end of the third pull rod 91 is fixedly connected to a second placement rack 92, and the inner side of the second placement rack 92 is fixedly sleeved with a number of evenly distributed isolation covers 93, and the number and position of the isolation covers 93 correspond to the number and position of the placement table 84.

[0038] It should be noted that when the second screw rod 4 rotates, the third pull rod 91 moves up and down along the second screw rod 4, thereby driving the second placement rack 92 to move up and down, and further driving the isolation cover 93 to move up and down.

[0039] like Figure 6 As shown, control valves 94 are fixedly connected to both sides of a plurality of isolation covers 93 .

[0040] It should be noted that the first screw rod 3 drives the first placement rack 83 to move downward, so that the fire extinguisher tank is completely immersed in water, and the control valve 94 is in an open state. The second screw rod 4 drives the isolation cover 93 to move downward, so that the lower edge of the isolation cover 93 is movably sleeved in the slot 85. At this time, the isolation cover 93 is completely immersed in water. When the water completely fills the inner side of the isolation cover 93, the control valve 94 is closed. After that, if air appears in the isolation cover 93, it is the gas leaked from the fire extinguisher tank.

[0041] like Figure 2 As shown, a valve is movably installed on the outer side of the water outlet pipe 7.

[0042] It should be noted that the valve is used to control the opening and closing of the water outlet pipe 7 to ensure whether the water in the water tank 1 flows out.

[0043] The working principle of the utility model is as follows: firstly, there are gears and motors in the first power mechanism 5 and the second power mechanism 6. The first power mechanism 5 can drive the four first screw rods 3 to rotate synchronously, and the second power mechanism 6 can drive the four second screw rods 4 to rotate synchronously. When the first screw rod 3 rotates, the first pull rod 81 moves up and down along the first screw rod 3, thereby driving the fixing frame 82 to move up and down, thereby driving the first placement frame 83 to move up and down. When the second screw rod 4 rotates, the third pull rod 91 moves up and down along the second screw rod 4, thereby driving the first placement frame 83 to move up and down. The second placement rack 92 moves up and down, thereby driving the isolation cover 93 to move up and down, and the first screw rod 3 drives the first placement rack 83 to move down, so that the fire extinguisher tank is completely immersed in the water, and the control valve 94 is in an open state. The second screw rod 4 drives the isolation cover 93 to move down, so that the lower edge of the isolation cover 93 is movably sleeved in the card slot 85. At this time, the isolation cover 93 is completely immersed in the water. When the water completely fills the inner side of the isolation cover 93, the control valve 94 is closed. After that, if air appears in the isolation cover 93, it is the gas leaked from the fire extinguisher tank. By removing the isolation cover 93, the fire extinguisher tank and The placement table 84 is completely immersed in water. After the water fills the inside of the isolation cover 93, the control valve 94 is closed. At this time, if the fire extinguisher tank leaks, the gas rises to the upper side of the isolation cover 93 to form an air cavity. By observing whether there is an air cavity, it is judged whether it is leaking. It is simple and efficient, and avoids the problem of leakage in the external pipeline connection caused by using an air pump to evacuate it. Finally, when the first screw 3 rotates, it drives the moving seat 871 to move up and down. When the moving seat 871 moves, it drives the cross fixing frame 872 to move up and down, and then drives the placement plate 873 to move up and down. The second pull rod 874 is used to support the placement plate 873 away from the side of the water tank 1, so that the front and rear sides of the placement plate 873 are balanced. By placing the external first placement rack 83 on the placement plate 873 in advance, the first power mechanism 5 drives the first screw 3 to rotate so that the moving seat 871 and the first pull rod 81 move up. When the previous batch of fire extinguisher tanks are detected, the entire first placement rack 83 is directly replaced to achieve the purpose of rapid detection, and the time in the process of detecting fire extinguisher tanks is fully utilized, so that the device can quickly detect a large number of fire extinguisher tanks.
