[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] like Figure 1 , Figure 2 As shown, the utility model provides a suspended sewage suction truck, comprising: a vehicle body 10, a tank body 20, an anti-overflow mechanism 30 and a vacuum pump 40; the tank body 20 is installed on the vehicle body 10, and is used to load sludge and sewage; the anti-overflow mechanism 30 comprises a cylinder body 31, a steel cage 32 and a float 33, the cylinder body 31 is provided with an air outlet on the upper part, an air inlet on the side wall, and a sewage outlet on the bottom, the inner wall of the cylinder body 31 forms an annular downward guide groove, the air inlet faces the guide groove, the top of the tank body 20 is connected with the air inlet through a pipeline, the steel cage 32 is installed on the cylinder body 31, and is located below the air outlet, the float 33 is placed on the steel cage 32, when the sewage inside the cylinder body 31 overflows the steel cage 32, the float 33 rises to seal the air outlet; the vacuum pump 40 is connected to the air outlet.

[0023] Through the setting of the overflow prevention mechanism 30, the overflow prevention mechanism 30 includes a cylinder 31, a steel cage 32 and a float 33. The inner wall of the cylinder 31 forms a circular downward guide groove, and the guide groove allows the gas and dirt in the cylinder 31 to rotate and flow. If the gas sucked into the cylinder 31 contains foreign matter, the foreign matter will fall to the bottom of the cylinder 31 due to its weight, and the air flow rises inside the cylinder 31 to prevent foreign matter from entering the vacuum pump 40. When sewage and dirt enter the cylinder 31, the sewage and dirt overflow the steel cage 32, and the float 33 in the steel cage 32 rises. The float 33 floats up and blocks the air outlet, preventing sludge and sewage from entering the vacuum pump 40, thereby protecting the vacuum pump 40.

[0024] like Figure 3 , Figure 4 As shown, in this embodiment, two float balls 33 are provided, and the two float balls 33 are located in the steel cage 32 .

[0025] like Figure 4 , Figure 5As shown, in this embodiment, specifically, the anti-overflow mechanism 30 further includes an inclined plate 34, a connecting pipe 35, a locking valve 36 and an observation window 37. The inclined plate 34 is obliquely installed on the inner wall of the cylinder 31, and a guide groove is formed between the inclined plate 34 and the cylinder 31, and the inclined plate 34 faces the air inlet. One end of the connecting pipe 35 is connected to one side of the cylinder 31, and the other end of the connecting pipe 35 is connected to the top of the tank 20, and the connecting pipe 35 faces the inclined plate 34. The locking valve 36 is installed at the bottom of the cylinder 31 to open and close the cylinder 31. The observation window 37 is installed on the cylinder 31 for observing the internal situation of the cylinder 31.

[0026] The arrangement of the inclined plate 34 guides the gas, sludge and sewage entering the cylinder 31 from the air inlet, so that the gas, sludge and sewage rotate downward and enter the cylinder 31.

[0027] By setting the locking valve 36 , the locking valve 36 can discharge sewage and dirt inside the cylinder 31 .

[0028] The observation window 37 allows the worker to observe the internal conditions of the cylinder 31 . If there is sewage and dirt in the cylinder 31 , the locking valve 36 can be opened to discharge the sewage and dirt in the cylinder 31 .

[0029] like Figure 4 As shown, in this embodiment, specifically, the barrel 31 includes a cylinder 311, a conical barrel 312 and an end cover 313, the end cover 313 is installed on the top of the cylinder 311, the conical barrel 312 is installed on the bottom of the cylinder 311, the air outlet is opened at the center of the top of the end cover 313, the air inlet is opened on the side wall of the cylinder 311, and the sewage outlet is opened at the bottom of the conical barrel 312.

[0030] In this embodiment, the air inlet is tangent to the side wall of the cylinder 311 .

[0031] like Figure 3 , Figure 4 As shown, in this embodiment, the suspended sewage suction truck, the anti-overflow mechanism 30 further includes a glass window 38 and an observation window 37, the glass window 38 is installed on the end cover 313. The observation window 37 is installed on the conical cylinder 312.

[0032] The arrangement of the observation window 37 and the glass window 38 allows the internal situation of the cylinder 31 to be observed.

[0033] The vehicle body 10 is provided with a ladder, and the ladder is located at one side of the tank body 20. The ladder facilitates workers to climb onto the tank body 20.

[0034] When in use, by turning on the vacuum pump 40, the vacuum pump 40 extracts the vacuum inside the tank body 20 through the anti-overflow mechanism 30. The anti-overflow mechanism 30 prevents sewage and dirt in the tank body 20 from entering the vacuum pump 40, thereby protecting the vacuum pump 40. When the gas and dirt rotate into the cylinder body 31 through the guide groove, if the gas sucked into the cylinder body 31 contains dirt, the dirt will fall to the bottom of the cylinder body 31 with its weight, and the air flow rises inside the cylinder body 31 to prevent foreign matter from entering the vacuum pump 40. When sewage and dirt enter the cylinder body 31, the sewage and dirt overflow the steel cage 32, and the float 33 in the steel cage 32 rises. The float 33 floats up to block the air outlet, thereby preventing sludge and sewage from entering the vacuum pump 40, thereby protecting the vacuum pump 40. After turning off the vacuum pump 40, the sewage and dirt inside the cylinder body 31 can be discharged by opening the locking valve 36.

[0035] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
