Solar automatic lifting system for rainwater grate

Abstract

The invention discloses a solar automatic lifting system for a rainwater grate; the solar automatic lifting system comprises a lifting device and a control mechanism which are arranged below the rainwater grate, and a solar power supply device which is externally arranged, wherein a mounting frame is detachably arranged on the sidewall of a drain well below the rainwater grate; the lifting device is composed of two shear arms which are relatively arranged and a linear motor; two ends of the shear arms are respectively arranged in the rainwater grate and a rail on the mounting frame in a sliding mode; the linear motor is arranged between the rainwater grate and the mounting frame; the control mechanism comprises an external rainfall sensor and a controller; and the controller is arranged inside the well wall of the sewer. The lifting system disclosed by the invention can be used for automatically lifting the rainwater grate according to rainfall, so as to solve the problem that rainwater cannot be removed timely in weathers of heavy rain and rainstorm since the cover of a conventional drain well cannot be opened timely.

Description

technical field [0001] The invention belongs to the field of mechanical automatic control, and in particular relates to a solar-powered automatic lifting system for rainwater grates. Background technique [0002] At present, the road drainage in urban areas mainly relies on the sewers arranged on the roadside. The opening of this sewer is a square, and a rainwater grate is provided to prevent large pieces of dirt from entering and blocking the sewer. Although the rainwater grate can realize sewage, The lower drainage of rainwater, but because the opening above the rainwater grate is small, when there is heavy rain or heavy rain, due to the factors of excessive rain and excessive rainfall, the rainwater is often not discharged in time, forming stagnant water, or even waterlogging, which often gives Inconvenience in our lives. Contents of the invention [0003] The purpose of the present invention is to provide a solar-powered automatic lifting system for rainwater grates, ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a solar-powered automatic lifting system for rainwater grates, which can sense the amount of rainfall through the installed rain sensor, and control the lifting device to raise the rainwater grate to increase the water flow and solve heavy rain 1. In the case of heavy rain, the rainwater cannot be removed in time caused by the failure of the traditional manhole cover to be opened in time, and the control system and lifting device are powered by the external solar power supply system
