Anti-overflow device and sewage suction truck
The invention relates to the technical field of spill-proof structures, and provides a spill-proof device and a sewage suction truck, the spill-proof device comprises a base, a floating ball, a ball frame and a sealing cover, the base is connected with a tank body of the sewage suction truck, the base is provided with a base inner cavity, a vacuum interface, an exhaust inlet and a dismounting through hole, and the vacuum interface, the exhaust inlet and the dismounting through hole are respectively connected with the base inner cavity and a vacuum pipeline; the exhaust inlet is respectively communicated with the inner cavity of the base and the tank body; the floating ball is used for sealing the exhaust inlet; the ball frame is located below the exhaust inlet and detachably connected with the base, the size of the ball frame is smaller than that of the dismounting through hole, and the floating ball is arranged in the ball frame and can float up and down along the ball frame; the sealing cover is detachably connected with the base and used for sealing the dismounting through hole. When the floating ball is cleaned or replaced, the sealing cover and the ball frame can be detached, and the ball frame and the floating ball can be taken out from the detaching through hole so as to clean or replace the floating ball, an operator does not need to enter the tank body and can clean or replace the floating ball outside the tank body, detaching is convenient, the base or the vacuum pipeline does not need to be detached, and the sealing performance of the anti-overflow device can be guaranteed.
本发明涉及防溢结构技术领域，提供一种防溢装置及吸污车，防溢装置包括基座、浮球、球框和密封盖，基座与吸污车罐体连接，基座设有基座内腔、分别与基座内腔和真空管路连接的真空接口、排气进口和拆装通孔，排气进口分别与基座内腔和罐体连通；浮球用于封闭排气进口；球框位于排气进口下方，球框与基座拆卸连接，球框的尺寸小于拆装通孔的尺寸，浮球设在球框内，浮球能沿球框上下浮动；密封盖与基座拆卸连接，密封盖用于封闭拆装通孔。对浮球进行清洗或更换时，可拆卸密封盖和球框，从拆装通孔中将球框和浮球取出，以清洗或更换浮球，操作人员无需进入罐体内，在罐体外部就可进行，拆装方便，无需拆装基座或真空管路，可保证防溢装置的密封性。
