Through the limiting mechanism and the replacement mechanism, it solves the problem that the container may shake unexpectedly during the installation process due to accidental operation or external impact, resulting in the spillage of hazardous chemicals inside the container and causing pollution to the external environment.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a replacement and testing device for barrelled hazardous chemicals, including a base plate, and several support blocks are fixedly connected to the top outer wall of the base plate; The inner wall of the support block is provided with a limiting mechanism, which includes a first positioning block. The outer wall of the first positioning block is fixedly connected to the inner wall of the support block. A telescopic rod is rotatably connected to the inner wall of the first positioning block. A rubber pressure plate is rotatably connected to the outer wall of the telescopic rod away from the first positioning block. A plurality of connecting rods are rotatably connected to the outer wall of the rubber pressure plate. A first slider is rotatably connected to the outer wall of the plurality of connecting rods away from the rubber pressure plate. A limiting rod is slidably connected to the inner wall of the first slider. A limiting groove is formed in the inner wall of the connecting rod. A second slider is slidably connected to the inner wall of the limiting groove. A support rod is rotatably connected to the outer wall of the second slider. A second positioning block is rotatably connected to the outer wall of the support rod away from the second slider.

[0005] Furthermore, a damper is fixedly connected to the outer wall of the second slider, a spring is fixedly connected to the outer wall of the damper, the outer wall of the limiting rod is fixedly connected to the inner wall of the support block, and a replacement mechanism is provided on the outer wall of the base plate.

[0006] Furthermore, the replacement mechanism includes a control device, the outer wall of which is fixedly connected to the outer wall of the base plate, and a support plate is fixedly connected to the top outer wall of the control device.

[0007] Furthermore, a collection tank is fixedly connected to the top outer wall of the support plate, a detector is fixedly connected to the bottom inner wall of the collection tank, and a valve is fixedly connected to the outer wall of the collection tank.

[0008] Furthermore, an electromagnetic three-way valve is fixedly connected to the outer wall of the valve, and an air pump is fixedly connected to the outer wall of the electromagnetic three-way valve at the end away from the valve. An inert gas storage tank is fixedly connected to the bottom outer wall of the air pump.

[0009] Furthermore, a connecting shell is fixedly connected to the bottom outer wall of the electromagnetic three-way valve, a rubber sealing ring is fixedly connected to the bottom outer wall of the connecting shell, and a gear turntable is rotatably connected to the inner wall of the connecting shell.

[0010] Furthermore, a number of limiting blocks are fixedly connected to the outer wall of the gear turntable, and a number of arc-shaped connecting rods are rotatably connected to the inner wall of the connecting shell. A rubber clamp is rotatably connected to the outer wall of the arc-shaped connecting rod away from the connecting shell.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates rubber pressure plates and connecting rods. The size of the container moves multiple rubber pressure plates on both sides, causing them to compress the telescopic rod, which then automatically shortens. Simultaneously, the telescopic rod rotates around the interior of the first positioning block. This allows the telescopic rod to support the movement of the rubber pressure plates, and the rubber pressure plates to clamp the container. The movement of the rubber pressure plates compresses the telescopic rod, and the friction of the telescopic rod increases the restraining force of the rubber pressure plates on the container. This prevents accidental shaking of the container during installation due to unforeseen operations or external impacts, which could lead to spillage of hazardous chemicals and environmental pollution.

[0013] 2. This utility model incorporates an arc-shaped connecting rod and rubber clamps. Rotating the gear turntable moves multiple limiting blocks, simultaneously pushing the arc-shaped connecting rod to rotate around the interior of the connecting shell. This causes the arc-shaped connecting rod to push the rubber clamps, clamping the portion of the container inserted into the connecting shell. A pin is inserted into the connecting shell, locking the gear turntable and preventing its rotation. The multiple rubber clamps hold the container interface in place. This design achieves the goal of using the rotation of the gear turntable to move the limiting blocks, which in turn moves the arc-shaped connecting rod, simultaneously moving the multiple rubber clamps to clamp the container interface. This prevents situations where different container interface sizes prevent stable connection with the detection device, thus avoiding the risk of container detachment due to vibrations during gas flow during the replacement process, which could lead to accidental leakage of hazardous chemicals and environmental pollution.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 As shown, this utility model is a replacement and testing device for barrelled hazardous chemicals, including a base plate 1, characterized in that: a plurality of support blocks 101 are fixedly connected to the top outer wall of the base plate 1; A limiting mechanism 2 is provided on the inner wall of the support block 101. The limiting mechanism 2 includes a first positioning block 201. The outer wall of the first positioning block 201 is fixedly connected to the inner wall of the support block 101. A telescopic rod 202 is rotatably connected to the inner wall of the first positioning block 201. A rubber pressure plate 203 is rotatably connected to the outer wall of the end of the telescopic rod 202 away from the first positioning block 201. After the rubber pressure plate 203 contacts the tank, the size of the tank pushes the rubber pressure plate 203 to move, while squeezing the telescopic rod 202 to shorten it and causing the telescopic rod 202 to rotate around the interior of the first positioning block 201. Several connecting rods 205 are rotatably connected to the outer wall of the rubber pressure plate 203. A first slider 204 is rotatably connected to the outer wall of the end of the connecting rods 205 away from the rubber pressure plate 203. A limiting rod 206 is slidably connected to the inner wall of the first slider 204. The movement of the rubber pressure plate 203 pushes the connecting rods 205 to rotate around the rubber pressure plate 203. While rotating inside, the connecting rod 205 pushes the first slider 204 to move along the inside of the limiting rod 206. A limiting groove 207 is formed on the inner wall of the connecting rod 205. A second slider 208 is slidably connected to the inner wall of the limiting groove 207. A support rod 209 is rotatably connected to the outer wall of the second slider 208. A second positioning block 210 is rotatably connected to the outer wall of the end of the support rod 209 away from the second slider 208. The rotation of the connecting rod 205 moves the second slider 208 while simultaneously pulling the support rod 209 to move around the second positioning block. While rotating, 210 pulls the second slider 208 to slide along the inside of the limiting groove 207. A damper 211 is fixedly connected to the outer wall of the second slider 208, and a spring 212 is fixedly connected to the outer wall of the damper 211. The movement of the second slider 208 pulls the damper 211, and the damper 211 is set to automatically pull the spring 212 when it is extended, thereby relieving the pressure on the second slider 208. The outer wall of the limiting rod 206 is fixedly connected to the inner wall of the support block 101, and the outer wall of the base plate 1 is provided with a replacement mechanism 3.

[0020] The replacement mechanism 3 includes a control device 301. The outer wall of the control device 301 is fixedly connected to the outer wall of the base plate 1. A support plate 302 is fixedly connected to the top outer wall of the control device 301. A collection tank 303 is fixedly connected to the top outer wall of the support plate 302. A detector 304 is fixedly connected to the bottom of the inner wall of the collection tank 303. The detector 304 is connected to the control device 301, so that the data detected by the detector 304 is transmitted to the screen on the surface of the control device 301. A valve 305 is fixedly connected to the outer wall of the collection tank 303, and the flow of gas is manually controlled by the valve 305. An ASCO electromagnetic three-way valve 306 is fixedly connected to the outer wall of the valve 305. The 356 series three-way solenoid valve features a high-performance design, large flow rate, and optimized flow path design, making it suitable for high flow rate requirements. It is applicable to medium and high pressures and has a wide operating pressure range. An air pump 307 is fixedly connected to the outer wall of the end of the solenoid three-way valve 306 away from the valve 305. An inert gas storage tank 308 is fixedly connected to the bottom outer wall of the air pump 307. The air pump 307 blows the gas in the inert gas storage tank 308 into the hazardous chemical tank connected at the bottom.

[0021] A connecting housing 309 is fixedly connected to the bottom outer wall of the electromagnetic three-way valve 306. A rubber sealing ring 315 is fixedly connected to the bottom outer wall of the connecting housing 309, blocking the connection between the tank body and the connecting housing 309 through the rubber sealing ring 315. A gear turntable 310 is rotatably connected to the inner wall of the connecting housing 309. Several limit blocks 311 are fixedly connected to the outer wall of the gear turntable 310. Several arc-shaped connecting rods 312 are rotatably connected to the inner wall of the connecting housing 309. The outer wall of the arc-shaped connecting rod 312 away from the connecting housing 309 rotates... A rubber clamp 313 is dynamically connected. The rotation of the gear turntable 310 pushes multiple limit blocks 311 to move, while pushing the arc-shaped connecting rod 312 to rotate around the inside of the connecting housing 309. At the same time, it drives the rubber clamp 313 to clamp the connecting pipe inside the connecting housing 309. A pin 314 is inserted into the inner wall of the connecting housing 309. The outer wall of the pin 314 is engaged with the outer wall of the gear turntable 310. The pin 314 is inserted into the inside of the connecting housing 309 and engages the outer teeth of the gear turntable 310.

[0022] One specific application of this embodiment is: When the equipment is needed, the hazardous chemical container is placed on top of the base plate 1. The container's size pushes multiple rubber pressure plates 203 on both sides to move, simultaneously causing the rubber pressure plates 203 to compress the telescopic rod 202, making it automatically shorten. The telescopic rod 202 rotates around the inside of the first positioning block 201, thus supporting the movement of the rubber pressure plates 203 and clamping the container. During the movement of the rubber pressure plates 203, two connecting rods 205 are pushed, causing them to rotate around the inside of the rubber pressure plates 203, while simultaneously pushing the first slider 204 to move. The movement range of the first slider 204 is limited by the limiting rod 206. During the rotation, the internal second slider 208 moves, pushing the support rod 209 to rotate around the interior of the second positioning block 210. Since the support rod 209 has a fixed size, its rotation pushes the second slider 208 along the interior of the limiting groove 207, causing the two second sliders 208 to pull the middle damper 211. The damper 211 alleviates the pressure and vibration on the rubber plate 203. The elasticity of the spring 212 outside the damper 211 also alleviates the pressure and vibration on the rubber plate 203, while simultaneously increasing the pressure on the rubber plate 203. Then, the container's outlet is inserted into the connecting shell 309, allowing air to pass through. A rubber sealing ring 315 at the bottom of the connecting housing 309 seals the gap between the connecting housing 309 and the container, thus preventing gas leakage. Then, rotating the gear turntable 310 moves multiple limit blocks 311, simultaneously pushing the arc-shaped connecting rod 312 to rotate around the interior of the connecting housing 309. This causes the arc-shaped connecting rod 312 to push the rubber clamps 313, clamping the portion of the container inserted into the connecting housing 309. Simultaneously, a pin 314 is inserted into the connecting housing 309, locking the gear turntable 310 and preventing its rotation. The multiple rubber clamps 313 clamp the container interface, preventing the container from vibrating and breaking during gas replacement. Displacement occurs, causing leakage between the connector and the container. Subsequently, the control device 301 controls the electromagnetic three-way valve 306, opening the pipe connection between the air pump 307 and the connecting housing 309. This allows the air pump 307 to draw inert gas from the inert gas storage tank 308 and blow it into the container through the electromagnetic three-way valve 306, thereby using the inert gas to expel the hazardous gas from the container. Then, by manipulating the electromagnetic three-way valve 306, the opened pipe is blocked again while the other pipe is opened. By manually rotating the valve 305, the previously expelled hazardous gas flows into the collection tank 303, where the detector 304 inside the collection tank 303 detects data such as gas composition.The detected data is transmitted via detector 304 to the control device 301 below and displayed on the screen of the control device 301.
