Dark pit warning sign setting device for urban waterlogging

Abstract

The invention discloses a dark pit warning sign setting device for urban waterlogging, and relates to the technical field of municipal warning devices. For the problem of potential safety hazards existing in the prior art, the following scheme is provided: the device comprises a fixed box and a dark pit; the upper side of the fixed box is in threaded connection with a supporting column; the top end of the supporting column is fixedly connected with a protective cover in a sleeved mode; the upper end of the supporting column is fixedly connected with a warning device through bolts; one side ofthe fixed box is fixedly connected with a telescopic device through bolts; a limiting plate is fixedly connected to the other end of the telescopic device; the limiting plate is in contact with a sidewall of the dark pit; and a plurality of weight blocks are clamped on one side of the fixed box. The device is simple in structure and convenient to use; the warning need can be well met; the warningeffect is enhanced; and data around the dark pit can be collected during use, so that the stability of the whole device is guaranteed, the warning effect is ensured, and the potential safety hazardsare avoided.

Description

technical field [0001] The invention relates to the technical field of municipal warning devices, in particular to a device for setting up warning signs for dark pits in urban waterlogging. Background technique [0002] Urban waterlogging refers to the phenomenon of accumulated water disasters in cities due to heavy or continuous precipitation exceeding the urban drainage capacity. The objective cause of waterlogging is the high intensity and concentrated range of rainfall. Where the rainfall is particularly urgent, water accumulation may form, and the rainfall intensity is relatively large and the time is relatively long. Water accumulation may also form. Due to the flow of groundwater, certain dark pits will be formed. Under the cover of water, it is very likely to endanger the personal safety of the people. If there is a threat, a warning must be given. However, the existing devices generally only use the poles to give a warning within a certain range, which not only ser...
