Reverse buckling type double-U clamping type submersible water impeller

Abstract

The invention discloses a reverse buckling type double-U clamping type submersible water impeller. The reverse buckling type double-U clamping type submersible water impeller comprises an underwater guide rail mounting seat, an impeller main machine and a lifting device, the bottom of the underwater guide rail mounting seat is fixed on the concrete at the bottom of a pool, the upper part of the underwater guide rail mounting seat is fixed on the concrete of the pool surface, the lifting device is fixed on the concrete on the pool surface, a supporting tenon block seat is fixed above the bottomof the underwater guide rail mounting seat, two inverted U-shaped supporting tenon blocks are symmetrically fixed above the supporting tenon block seat, a reverse buckling type double-U clamping device is arranged above the two inverted U-shaped supporting tenon blocks, the reverse buckling type double-U clamping device comprises two reverse buckling type double-U clamping frames which are symmetrically arranged and a connecting plate which is used for connecting the two reverse buckling type double-U clamping frames, each reverse buckling type double-U clamping frame is an inverted U-shapedconcave structure, the two reverse buckling type double-U clamping frames are longitudinally and symmetrically arranged along the central line of an impeller, and a reverse buckling type double-U-shaped rubber pad is arranged between the reverse buckling type double-U clamping frames and the inverted U-shaped supporting tenon blocks.

Description

technical field [0001] The invention relates to the field of urban domestic sewage treatment and special equipment for sewage treatment, in particular to an inverted double-U clamping type submersible pusher. Background technique [0002] The submersible flowmeter is a mechatronic submersible device that is driven by a motor reduction mechanism to rotate the impeller. It is widely used in the field of urban domestic sewage treatment. It stirs sewage and sludge, promotes the flow of water media, and retards the settlement of sludge. It is a sewage The key core equipment of the treatment plant is composed of three parts, one is the main engine of the flow booster, the other is the underwater guide rail mounting seat, and the third is the lifting device. The main engine of the equipment works at a position about 6 meters underwater, so the underwater guide rail The mounting seat is fixed on the bottom of the underwater pool, and the lifting device is installed on the surface of...

[0002] The submersible flowmeter is a mechatronic submersible device that is driven by a motor reduction mechanism to rotate the impeller. It is widely used in the field of urban domestic sewage treatment. It stirs sewage and sludge, promotes the flow of water media, and retards the settlement of sludge. It is a sewage The key core equipment of the treatment plant is composed of three parts, one is the main engine of the flow booster, the other is the underwater guide rail mounting seat, and the third is the lifting device. The main engine of the equipment works at a position about 6 meters underwater, so the underwater guide rail The mounting seat is fixed on the bottom of the underwater pool, and the lifting device is installed on the surface of the water pool. The main body of the flow booster is lifted by the lifting device on the water, and slides down along the guide rail until the mounting seat at the bottom of the underwater pool is in place. If it needs to be pulled up, it is directly lifted by the lifting device. Lifting and moving up along the guide rail, there are three major defects in the traditional equipment technology: First, the structure of the underwater mounting seat is flat, which cannot effectively fix and clamp the flow booster placed on it. Underwater operation is prone to vibration and noise. Second, the working state of the flow booster is not naturally fixed and fastened by matching special settings, and it cannot form a matching structure for effective underwater fixing with the mounting seat. Third, the traditional understanding There is a big misunderstanding. I always think that the high failure of the flow booster equipment is due to the poor quality of the flow booster host. As a result, domestic manufacturers blindly improve the quality of the host, while ignoring the overall systemic and integrated supporting requirements of the equipment, and even ignoring the quality of the equipment. The harshness, complexity and concealment of the underwater working conditions, and the failure to effectively fix and clamp the equipment underwater is the root cause of failure, vibration and short life
