Abstract
The utility model discloses a manual locking device for a sewage suction tank of a combined sewage suction truck. The manual locking device is used for locking a rear cover with a tank body of the sewage suction tank of the combined sewage suction truck, the sewage suction tank comprises the tank body and the rear cover of the tank body, and the manual locking device is arranged between the tank body of the sewage suction tank and the rear cover, and is connected with the sewage suction tank through a fixing hook arranged on the tank body and a fixing seat arranged on the rear cover. The manual locking device effectively solves problems that when a hydraulic locking mode is adopted by an existing sewage suction tank of a combined sewage suction truck, leakage can be caused easily if the pressure in the tank is positive, so that secondary pollution to environments is caused, and certain potential safety hazards are easy to cause.
Description
Technical field
The utility model relates to sewage conduct mediation equipment technical field, is specifically related to the automobile-used dirt-absorption tank manual locking device of a kind of combined suction sewage.
Background technology
Combined suction sewage truck is mainly used in sewage, mud and the sandstone, large-scale of all kinds of underground sewers in city, catch-basin and inspection shaft; The suction of block, transport, remove stage makeup and costume, can be used for the desilting and the mediation in suction, transportation and small-sized river course of sewage, industrial waste oil and the waste water of large-scale industrial enterprise simultaneously.At present; The bonnet of the dirt-absorption tank of existing suction-type sewer scavenger adopts the hydraulic locking mode usually; This kind locking mode is only applicable to dirt-absorption tank inside usually and is the tank body of negative pressure, can not be applicable to that soil pick-up filling inside is the tank body of malleation, if soil pick-up is irritated the tank body employing hydraulic locking mode that inside is malleation; Tank body can occur soil pick-up irritate in material race, leakage phenomenon such as emit, leak, drip, cause second environmental pollution and certain potential safety hazard.
Summary of the invention
The technical problem that the utility model will solve provides the automobile-used soil pick-up of a kind of combined suction sewage and irritates manual locking device; The utility model efficiently solves when having combined suction sewage truck dirt-absorption tank employing hydraulic locking mode now; If leakage phenomenon appears in a jar internal pressure easily when being malleation; Thereby cause generation, also cause certain security hidden trouble simultaneously easily the second environmental pollution problem.
The utility model is realized through following technical scheme:
The automobile-used dirt-absorption tank manual locking device of a kind of combined suction sewage; Be used for the locking of the tank body and the bonnet of combined suction sewage truck dirt-absorption tank; The tank body and the bonnet thereof that comprise dirt-absorption tank; Be provided with manual locking device between said dirt-absorption tank tank body and the bonnet, manual locking device is connected with dirt-absorption tank through the holder that is provided with on the stay hook that is provided with on the tank body and the bonnet.
The further Technological improvement plan of the utility model is:
Said manual locking device comprises handwheel, screw rod, draw ring, and screw rod is fixedly connected with draw ring, and handwheel is connected with screw flight.
The utility model compared with prior art has following obvious advantage:
One, the utility model adopts manual locking device, when dirt-absorption tank jar internal pressure is malleation, can stop soil pick-up irritate in the race, the generation of leakage phenomenon such as emitting, leak, dripping of material, improved the environmental-protecting performance of suction-type sewer scavenger;
Two, the utility model liquid adopts manual locking device, has improved dirt-absorption tank security performance in the process of moving.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial enlarged drawing of looking up of Fig. 1 manual locking device.
The specific embodiment
Like Fig. 1, shown in 2; Be used for the locking of tank body 2 with the bonnet 1 of combined suction sewage truck dirt-absorption tank, comprise the tank body 2 and the bonnet 1 thereof of dirt-absorption tank, be provided with manual locking device 5 between dirt-absorption tank tank body 2 and the bonnet 1; Manual locking device 5 is connected with dirt-absorption tank through the holder 4 of setting on the stay hook 3 that is provided with on the tank body 2 and the bonnet 1; Manual locking device 5 comprises handwheel 51, screw rod 52, draw ring 53, and screw rod 52 is fixedly connected with draw ring 53, and handwheel 51 is threaded with screw rod 52.
The course of work in conjunction with Fig. 1,2 summary the utility model:
Screw rod 52 1 ends pass holder 4, and handwheel 51 is threaded with screw rod 52, and screw rod 52 is fixedly connected with stay hook 3 through the draw ring 53 that the other end is fixedly connected with it, realize the locking and the unlatching of bonnet 1 at last through the direction of rotation hand wheel 51.
The utility model has reached the foregoing invention purpose in sum.
