Hydraulic swing type jet flushing device

Abstract

The invention provides a hydraulic swing type jet flushing device which is fixedly arranged at the bottom of a storage pond. The hydraulic swing type jet flushing device comprises a fixing support, a flushing water pump, a jet unit and a first swing unit, the flushing water pump and the jet unit are connected to different sides of the fixing support respectively, and the jet unit communicates with a water supply pipe of the outlet of the flushing water pump and provided with a water outlet pipe set. The water outlet pipe set comprises a connecting elbow, a first rotating joint and a water outlet pipe which are sequentially communicated; and the first swing unit comprises a water wheel and a swing rod, and the water wheel is rotationally arranged in a cylinder arranged in the middle of the connecting elbow. One end of the swing rod is eccentrically rotatably connected with one end, extends outside the cylinder, of the water wheel, the other end of the swing rod is in sliding connection with the outer side wall of the water outlet pipe, so that a crank connecting rod mechanism is formed. According to the hydraulic swing type jet flushing device, the water outlet pipe can be driven to swing up and down in a vertical plane through hydraulic action on the crank connecting rod mechanism formed by the water wheel and the swing rod, so that the water outlet angle is adjusted, the water falling point is changed to expand the flushing range, and the flushing effect of water flow on the bottom of the storage pond is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a hydraulic swing jet flushing device. Background technique [0002] As a rainwater collection facility, the storage tank is widely used under urban roads, buildings and other areas. It can store large-flow rainwater in a short period of time, and discharge it after the rainwater flow decreases to ensure the smooth flow of the urban sewer system. Avoid the flood peak of large flow and play the role of regulating drainage. [0003] The storage tank is usually built underground. During the storage process, impurities in the rainwater will settle on the bottom of the tank, causing siltation at the bottom of the tank, which will affect the use of the storage tank for a long time, so it needs to be cleaned in time. [0004] The cleaning of the existing storage tanks mainly relies on manual work or the use of jet flushing devices for jet cleaning, and the jet flushin...

AI Technical Summary

Problems solved by technology

At present, the jet flushing device is usually fixed at a certain position on the bottom of the pool, and the outlet angle of the outlet pipe is usually constant. Therefore, the flushing distance of the parabolic water flow sprayed by the outlet pipe (that is, the distance from the outlet to the water drop point) is a certain value. Except for the farthest falling water point that can be washed, most of the bottom of the pool cannot be washed directly. It can only be cleaned by the agitation of the water flow after washing, and the cleaning effect is not good.

It can be seen that the existing jet flushing device has the technical problem of incomplete flushing at the bottom of the pool due to the constant water discharge angle and the fact that the sediment cannot be completely flushed and stirred up.
