A mud suction device that can arbitrarily change the diameter of the mud suction port for deep wells

Abstract

The invention relates to the technical field of deep well dredging equipment, and discloses a mud suction device for deep wells and capable of arbitrarily changing the diameter of a mud suction port.The mud suction device comprises a casing, an annular pipe, a mud suction pipe and a sensor group arranged on the pipe wall of the mud suction pipe, and is characterized in that a baffle and a sealingplate are fixedly connected to the inner edge of a pipe opening at the upper end and the inner edge of a pipe opening at the lower end of the casing respectively, a mounting pipe is fixedly connectedto the opposite sides of the baffle and the sealing plate jointly, a transmission mechanism is connected into the mounting pipe, a plurality of obliquely arranged liquid passing channels are arrangedbetween the upper side and the lower side of the sealing plate in a penetrating mode, and the multiple liquid passing channels are distributed in a ring shape. The mud suction device for the deep wells and capable of arbitrarily changing the diameter of the mud suction port can arbitrarily adjust the diameter of the mud suction device within a certain diameter range, and is suitable for deep wells with different diameters, and the mud suction device can further be lowered to the well bottom to form a closed area, so that the situation that clean water is polluted due to the fact that sludge at the well bottom is prone to spreading to the surrounding water is avoided.

Description

technical field [0001] The invention relates to the technical field of deep well desilting equipment, in particular to a dredging device for deep wells, which can change the diameter of the dredging port arbitrarily. Background technique [0002] The urban drainage system is an engineering facility system for treating and removing urban sewage and rainwater. It is an integral part of urban public facilities. The urban drainage system is usually composed of rainwater cellars, drainage pipes and sewage treatment plants. In the case of sewage and rainwater diversion systems Next, the sewage is collected by the drainage pipe and sent to the sewage treatment. After the rainwater runoff is collected by the drainage pipe, it is discharged into the nearby water body. In order to reduce the sediment deposition in the rainwater pipe, the rainwater cellar is mostly designed as a deep well, which can effectively deposit mud. To reduce the trouble of pipe clogging, it only needs to clean...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a dredging device for deep wells that can arbitrarily change the diameter of the dredging port. It is equipped with the ability to arbitrarily adjust the diameter of the dredging device within a certain diameter range, and is suitable for deep wells of different diameters. , and after the mud suction device is lowered to the bottom of the well, a closed area can be formed, and the sludge at the bottom of the well is not easy to spread to the surrounding water body to cause pollution of the clear water. To clean up the sludge, the dredging device cannot form a closed space when cleaning the bottom sludge, and the sludge at the bottom of the well will spread around and make the upper clear water turbid again, which increases the difficulty of cleaning and the problem of working time
