An inlet valve 303 is installed on the side of the inner embedded pipe 302 facing the inside of the water bucket 1 inside the connecting pipe 301, and the inlet valve 303 is in the shape of a conical hopper. When the inlet valve 303 fits with the inner embedded pipe 302, it can block the accumulated water from flowing into the water bucket 1. A conduit 304 communicating with the connecting pipe 301 is fixedly installed on the outer side of the connecting pipe 301 inside the water bucket 1, and the conduit 304 is located between the inner embedded pipe 302 and the inlet valve 303. A pin 305 is fixedly installed on the side of the inlet valve 303 away from the inner embedded pipe 302, and the pin 305 penetrates the closed end of the connecting pipe 301. The connection mode between the pin 305 and the connecting pipe 301 is pluggable connection. The inlet valve 303 is made of elastic rubber.

[0029] Please refer to Figure 2 、 Figure 3, at the closed end of the connecting pipe 301, a connecting rod 306 is hinged and installed on the lower side of the pin 305. One end of the connecting rod 306 away from the connecting pipe 301 is fixedly connected to a floating ball 307. A push rod 308 is fixedly installed on the outer side of the connecting rod 306, and the connection between the push rod 308 and the pin 305 is an active abutment. The push rod 308 can drive the pin 305 to move. The blocking structure 4 includes a rubber piston 401 that is movably embedded in the drain pipe 2 and can move up and down inside the drain pipe 2. At the center of the upper end of the rubber piston 401, a spline rod 402 is fixedly embedded, and the outer wall of the rubber piston 401 is in active fit with the inner wall of the drain pipe 2.

[0030] Please refer to Figure 5 , at one end of the spline rod 402 away from the rubber piston 401, a cushion block 403 is fixedly sleeved. A first sleeve 404 is movably sleeved on the outer side of the cushion block 403, and the upper end of the first sleeve 404 is fixedly connected to the top of the water bucket 1. The cushion block 403 can prevent the spline rod 402 from detaching from the first sleeve 404. At the center of the upper end of the water bucket 1, an electric push rod 405 is fixedly installed, and the telescopic rod of the electric push rod 405 is fixedly embedded at the center of the upper end of the cushion block 403. The electric push rod 405 can drive the rubber piston 401 to move up and down. A spring 406 is fixedly sleeved on the outer side of the telescopic rod of the electric push rod 405 inside the first sleeve 404, and the two ends of the spring 406 are in active abutment with the cushion block 403 and the water bucket 1 respectively.

[0031] The working principle of quantitatively discharging accumulated water to avoid a large amount of accumulated water splashing: When recovering the exhaust gas of a dangerous goods vehicle, the operator docks the recovery pipe with the connecting pipe 301 on the water bucket 1, and then discharges the exhaust gas and accumulated water in the dangerous goods vehicle through the recovery pipe. The exhaust gas and accumulated water enter the inside of the water bucket 1. The accumulated water is temporarily stored inside the water bucket 1, and the exhaust gas is discharged and collected through the exhaust pipe 9. When the accumulated water inside the water bucket 1 reaches a certain height, the floating ball 307 will rotate to a horizontal state under the action of buoyancy. During the rotation of the floating ball 307, the push rod 308 installed on the connecting rod 306 will drive the pin 305 to move, and the pin 305 will drive the inlet valve 303 to fit with the tapered end of the inner embedded pipe 302 to block the inner embedded pipe 302. At this time, the accumulated water cannot enter the inside of the water bucket 1, and a certain amount of accumulated water is stored inside the water bucket 1;

[0032] When discharging the accumulated water inside the water bucket 1, the operator controls the electric push rod 405 to operate. The electric push rod 405 drives the rubber piston 401 to move up a certain distance through the spline rod 402. At this time, the accumulated water inside the water bucket 1 is discharged through the rectangular through groove 7 on the outer side of the drain pipe 2. By quantitatively discharging the accumulated water in the recovery pipe through the water bucket 1, the inlet structure 3 and the blocking structure 4, it is possible to avoid a large amount of accumulated water being discharged at one time, causing the accumulated water to splash onto the skin of the operator and causing potential harm to the human body when the amount of accumulated water is unknown.

[0033] Embodiment 2

[0034] Please refer to Figure 4 and Figure 6 In this embodiment, for further illustration of the first embodiment, the cleaning structure 5 includes a silicone scraping strip 501 that is movably attached to the inner wall of the water bucket 1. A fixed skeleton 502 is fixedly installed on the silicone scraping strip 501, and a positioning rod 503 is fixedly installed on the outer side of the fixed skeleton 502. The connecting component 6 includes a sleeve two 601 that is rotatably connected to the sleeve one 404 through a bearing. An arc-shaped chute 602 is opened on the inner wall of the sleeve two 601. A pin 603 is movably embedded in the arc-shaped chute 602, and the pin 603 is fixedly connected to the spline rod 402. A hemispherical portion is provided at one end of the pin 603 located inside the arc-shaped chute 602.

[0035] In this embodiment: When the electric push rod 405 drives the rubber piston 401 to move up and down, the pin 603 fixed on the spline rod 402 also moves up and down accordingly. During the up and down translation of the pin 603, the pin 603 can drive the sleeve two 601 and the silicone scraping strip 501 to rotate reciprocally left and right by 180° through the arc-shaped chute 602. Since the silicone scraping strip 501 is movably attached to the inner wall of the water bucket 1, the silicone scraping strip 501 can scrape off the dirt attached to the inner wall of the water bucket 1 during the rotation process, so that the inner wall of the water bucket 1 can be automatically cleaned.

[0036] Embodiment Three

[0037] Please refer to Figure 4 In this embodiment, for further illustration of the second embodiment, a plurality of circular through holes 8 are opened on the fixed skeleton 502 and are equally spaced.

[0038] In this embodiment: The plurality of circular through holes 8 opened on the fixed skeleton 502 enable the accumulated water to pass through the circular through holes 8, so that during the rotation of the fixed skeleton 502, the resistance of the accumulated water to the rotation of the fixed skeleton 502 can be reduced.
