Hidden automatic lifting trash holding and overhauling system for water inlet of flood drainage project

Abstract

The invention discloses a hidden automatic lifting trash holding and overhauling system for a water inlet of a flood drainage project. The hidden automatic lifting trash holding and overhauling systemmainly comprises a vertical shaft type water inlet, a floating box type gate, a vertical stainless steel trash rack, a horizontal stainless steel trash rack, a control room and an overhauling channel. A trash holding and overhauling device is hidden underwater, the original water surface landscape can be prevented from being damaged, and the project investment can be saved. The floating box typegate serves as an overhauling gate in the non-flood drainage period and also serves as a sand blocking ridge in the flood drainage period, and after the vertical trash rack is additionally arranged atthe top, secondary blocking can be conducted on trash. The gate is in a floating box type, the buoyancy of water is fully utilized while the dead weight is reduced, a hydraulic pushing mechanism is adopted as opening and closing power, and reliability is high. According to the hidden automatic lifting trash holding and overhauling system, overhauling and trash holding are automatically controlled, manual wading operation is avoided in the flood drainage period, and safety is guaranteed.

Description

Technical field [0001] The invention relates to a pollution blocking maintenance technology in a waterlogging drainage project, in particular to a hidden automatic lifting pollution blocking maintenance system for the water intake of a waterlogging drainage project which has special requirements on the architectural landscape and is suitable for many floating objects during the drainage period. Background technique [0002] For water intakes of drainage projects built in urban wetlands, parks, rivers and lakes, etc., the requirements for landscape effects are usually high. According to conventional practices, the pollution prevention and repair must be carried out by arranging gates, pollution prevention facilities and supporting facilities around the inlets. The upper building is realized, and the part of the building exposed to the water surface is relatively abrupt and difficult to coordinate with the original landscape on the water surface. [0003] In addition, when the discha...

AI Technical Summary

Problems solved by technology

[0002] For the water inlets of flood drainage projects built in urban wetlands, parks, rivers and lakes, etc., there are usually high requirements for landscape effects. According to conventional practices, the maintenance of the pollution control must be done by arranging gates, pollution blocking facilities and supporting facilities around the water inlets. The upper part of the building is realized, and the part of the building exposed to the water is rather abrupt, and it is difficult to coordinate with the original landscape of the water surface

[0003] In addition, in the case of large flood discharge flow and flow velocity, the water flow often carries a large amount of dirt and sediment, which can easily cause blockage and siltation of the water inlet. It is difficult to remove and remove the trash facilities around the water inlet in time. , the safety risk is relatively large during manual wading and cleaning
