Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a gaseous fire extinguishing agent leakage detection device. Background Technology

[0002] Gas extinguishing agents are special gaseous substances used for fire extinguishing. They are generally stored under high pressure in specific steel cylinders. After filling, it is necessary to test for leaks to ensure the normal use of the gas extinguishing agent. Therefore, a detection device is required.

[0003] A Chinese patent with authorization announcement number CN215275564U discloses a pipe network type heptafluoropropane fire extinguishing device with leakage detection function, including a bottleneck section. The bottleneck section has a sensing component installed inside for sensing gas flow, and a warning device is installed on the outside of the bottle body for warning of leakage. The warning device is electrically connected to the sensing component. This application has the feature of being able to detect whether the pipe network type heptafluoropropane fire extinguishing device is leaking, thereby improving the reliability of the pipe network type heptafluoropropane fire extinguishing device.

[0004] However, the above-mentioned device still has some problems. In practical applications, when detecting gaseous fire extinguishing agent leaks, tiny bubbles are difficult to observe, which increases the risk of missed detection and makes it impossible to determine in a timely and accurate manner whether there is a leak in the fire extinguishing agent, thus affecting the accuracy of the detection results. Therefore, a gaseous fire extinguishing agent leak detection device is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems mentioned in the background art, this utility model proposes a gas extinguishing agent leakage detection device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The gas extinguishing agent leakage detection device of this utility model includes a box body. A bubble amplification component is assembled on one side of the box body. The bubble amplification component includes a through groove. A through groove is formed inside one side of the box body. Sliding grooves are formed on both sides of the through groove inside the box body. The sliding grooves are connected to the through groove. A sliding strip is slidably installed inside the sliding groove. A mounting frame is fixedly connected to one side of the sliding strip. The mounting frame is slidably installed inside the through groove. A handle is assembled on the top side of the mounting frame. A magnifying lens is assembled inside the mounting frame. Two locking screws are symmetrically rotated and installed inside one side of the box body. One end of each locking screw abuts against one side of the sliding strip. This allows for clear observation of the magnified bubbles, facilitating timely detection of leaks. The magnifying lens is easy to disassemble and clean, maintaining detection accuracy.

[0007] Preferably, a rotating shaft is rotatably mounted inside one side of the housing, a driven gear is mounted on the outer wall of the rotating shaft, an L-shaped seat is mounted on one side of the housing, a drive motor is mounted inside the L-shaped seat, and a driving gear is mounted on the output end of the drive motor. The driving gear and the driven gear mesh with each other to achieve continuous detection operations and improve detection efficiency.

[0008] Preferably, a mounting plate is installed inside the housing on one side of the rotating shaft. Four rotating handles are equidistantly mounted on the outer wall of the mounting plate. A bidirectional lead screw is installed at one end of each rotating handle. Four sets of two slide rails are equidistantly arranged inside the mounting plate. A slider is slidably installed inside each slide rail. A screw hole is opened inside each slider. One end of the bidirectional lead screw passes through the screw hole and is rotatably mounted on the inner wall of one side of the slide rail. Each set of sliders is fixed with an arc-shaped clamp, and the arc-shaped clamps are symmetrically arranged, which realizes stable fixation of steel cylinders of different sizes and ensures that the steel cylinders will not shake or fall off during the testing process.

[0009] Preferably, the inner wall of the arc-shaped clamp is equipped with friction pads to increase the friction between the gas cylinder and the arc-shaped clamp, making the gas cylinder more stable when clamped.

[0010] Preferably, a drain pipe is connected to one side of the bottom of the box, and a valve is installed on the outer wall of the drain pipe to facilitate the discharge of water after the test is completed.

[0011] Preferably, a control panel is installed on one side of the housing, and the control panel controls the operation of the electrical components inside the device, realizing centralized control of the electrical components in the device.

[0012] The advantages of this utility model are:

[0013] 1. When a steel cylinder containing a gaseous fire extinguishing agent is placed in water, if there is a leak in the fire extinguishing agent, bubbles will be generated. At this time, the magnifying lens can magnify the bubbles, allowing the staff to observe the generation and changes of the bubbles more clearly, which helps to detect the fire extinguishing agent leak in time. When it is necessary to disassemble and clean the magnifying lens, rotate the locking screw in the opposite direction to prevent it from pressing against the slide bar. Then, slide the mounting frame out of the through groove through the handle to clean the magnifying lens and maintain the detection accuracy.

[0014] 2. This utility model places the steel cylinder between two arc-shaped clamps. Rotating the handle drives the bidirectional lead screw to rotate, causing the slider to slide within the slide rail. This brings the two arc-shaped clamps closer together, clamping the steel cylinder and ensuring it won't shake or fall off during testing. Then, the drive motor can be started, and its output gear rotates. The drive gear meshes with the driven gear, driving the rotating shaft and mounting plate to rotate. This positions the steel cylinder at the bottom of the mounting plate inside the water tank. At this point, the steel cylinder at the top can be removed, and the cylinder to be tested can be placed there. This allows for continuous testing of steel cylinders, improving testing efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-3 As shown, a gas extinguishing agent leak detection device includes a housing 1. A bubble amplification component is mounted on one side of the housing 1. The bubble amplification component includes a through groove 2. The through groove 2 is formed through the interior of one side of the housing 1. Sliding grooves 3 are formed on both sides of the through groove 2 inside the housing 1, and the sliding grooves 3 are connected to the through groove 2. Sliding strips 4 are slidably installed inside the sliding grooves 3. A mounting frame 5 is fixedly connected to one side of the sliding strips 4. The mounting frame 5 is slidably installed inside the through groove 2. A handle 6 is mounted on the top side of the mounting frame 5. A magnifying lens 7 is mounted inside the mounting frame 5. Two locking screws 8 are symmetrically rotated and installed inside one side of the housing 1. During operation, in practical applications, when detecting gas extinguishing agent leaks, tiny bubbles are difficult to observe, which increases the risk of missed detection and makes it impossible to make timely and accurate judgments. To check for leaks in the extinguishing agent, which affect the accuracy of the test results, a magnifying lens 7 needs to be installed. To do this, insert the sliding strips 4 on both sides of the mounting frame 5 into the sliding groove 3 using the handle 6. Then, slide the mounting frame 5 into the through groove 2. Next, rotate the locking screw 8 so that one end of it abuts against one side of the sliding strip 4, thus fixing the mounting frame 5 in the through groove 2. When a cylinder containing gaseous extinguishing agent is placed in the water inside the box 1, if there is a leak, bubbles will be generated. The magnifying lens 7 can magnify these bubbles, allowing staff to observe their generation and changes more clearly, helping to detect leaks promptly. When the magnifying lens 7 needs to be disassembled and cleaned, rotate the locking screw 8 in the opposite direction to loosen its contact with the sliding strip 4. Then, slide the mounting frame 5 out of the through groove 2 using the handle 6 to clean the magnifying lens 7 and maintain testing accuracy.

[0024] Please see Figure 1 , 2 As shown in Figures 4 and 5, a rotating shaft 9 is rotatably mounted inside one side of the housing 1, a driven gear 10 is mounted on the outer wall of the rotating shaft 9, an L-shaped seat 11 is mounted on one side of the housing 1, a drive motor 12 is mounted inside the L-shaped seat 11, and a driving gear 13 is mounted on the output end of the drive motor 12. The driving gear 13 meshes with the driven gear 10.

[0025] A mounting plate 14 is installed inside the housing 1 on one side of the rotating shaft 9. Four rotating handles 15 are equidistantly mounted on the outer wall of the mounting plate 14. A double-acting lead screw 16 is installed at one end of each rotating handle 15. Four sets of two slide rails 17 are equidistantly arranged inside the mounting plate 14. A slider 18 is slidably mounted inside each slide rail 17. Each slider 18 has a screw hole inside. One end of the double-acting lead screw 16 passes through the screw hole and is rotatably mounted on the inner wall of one side of the slide rail 17. Each set of sliders 18 is fixedly connected to an arc. The box 1 has two symmetrically arranged arc-shaped clamps 19. The inner walls of each arc-shaped clamp 19 are fitted with friction pads. A drain pipe 20 is connected to one side of the bottom of the box 1. A valve 21 is fitted on the outer wall of the drain pipe 20. A control panel 22 is installed on one side of the box 1. During operation, after the gaseous fire extinguishing agent is filled, a leak test is required to ensure the normal use of the gaseous fire extinguishing agent. Therefore, a detection device is needed. When it is necessary to fix the cylinder, the cylinder is placed between two arc-shaped clamps 19, and the rotating handle 15 is turned. This causes the bidirectional lead screw 16 to rotate, and the slider 18 to slide within the slide rail 17, bringing the two arc-shaped clamping plates 19 closer together to clamp the gas cylinder. This achieves stable fixation of gas cylinders of different sizes, ensuring that the gas cylinder will not shake or fall off during the testing process. Furthermore, the friction pads increase the friction between the arc-shaped clamping plates 19 and the gas cylinder, making the cylinder more stably clamped. Then, the drive motor 12 can be started, and its output drive gear 13 rotates. The drive gear 13 meshes with the driven gear 10, thereby driving the rotating shaft 9 and the mounting plate 1. 4. Rotate the cylinder so that the cylinder at the bottom of the mounting plate 14 is inside the water in the tank 1. At this time, the cylinder at the top can be removed and the cylinder to be tested can be placed. This enables continuous testing of the cylinders and improves testing efficiency. After the test is completed, the water in the tank 1 needs to be drained. Open the valve 21 on the outer wall of the drain pipe 20 so that the water can flow out of the tank 1 through the drain pipe 20. This makes it easy to clean the tank 1 quickly after the test and prepare for the next test. It should be noted that the speed of the drive motor 12 needs to be controlled to avoid large fluctuations in the water.

[0026] Working principle: When installing the magnifying lens 7, insert the sliding strips 4 on both sides of the mounting frame 5 into the sliding groove 3 using the handle 6, then slide the mounting frame 5 into the through groove 2. Next, rotate the locking screw 8 so that one end of it abuts against one side of the sliding strip 4, thereby fixing the mounting frame 5 in the through groove 2. When fixing the gas cylinder, place the gas cylinder between the two arc-shaped clamps 19, rotate the rotating handle 15, driving the double-acting screw 16 to rotate, and the slider 18 slides in the slide rail 17, causing the two arc-shaped clamps 19 to move closer together and clamp the gas cylinder. The cylinder is used to stably fix steel cylinders of different sizes, ensuring that the cylinders will not shake or fall off during the testing process. With the help of the friction pad, the friction between the arc-shaped clamp 19 and the steel cylinder is increased, making the steel cylinder more stable. When the steel cylinder containing the gas extinguishing agent is placed in the water in the box 1, if there is a leak of extinguishing agent, bubbles will be generated. At this time, the magnifying lens 7 can magnify the bubbles, allowing the staff to observe the generation and changes of the bubbles more clearly, which helps to detect the leak of extinguishing agent in time.

[0027] Then, the drive motor 12 can be started, and the drive gear 13 at its output end rotates. The drive gear 13 meshes with the driven gear 10, thereby driving the rotating shaft 9 and the mounting plate 14 to rotate, so that the steel cylinder at the bottom of the mounting plate 14 is inside the water in the box 1. At this time, the steel cylinder at the top can be taken out and the steel cylinder to be tested can be placed, realizing continuous testing of the steel cylinder and improving the testing efficiency. After the test is completed, the water in the box 1 needs to be drained. Open the valve 21 on the outer wall of the drain pipe 20, and the water can flow out of the box 1 through the drain pipe 20, which facilitates quick cleaning of the box 1 after the test and prepares for the next test. When it is necessary to disassemble and clean the magnifying lens 7, rotate the locking screw 8 in the opposite direction so that it no longer presses against the slide bar 4. Then, slide the mounting frame 5 out of the through groove 2 through the handle 6 to clean the magnifying lens 7 and maintain the testing accuracy.
