Fig. 2 is a top view of the fixing plate of the present invention.

In the figure: 1 fixed plate, 2 filter screens, 3 bracing pieces, 4 positive and negative rotating motors, 5 chutes, 6 sliders, 7 linkage disks, 8 threaded rods, 9 threaded pipes, 10 plugs, 11 handles, 12 warning boards and 13 pin shafts.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Embodiments of the device are given in the figures. However, the apparatus may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Examples

As shown in fig. 1-2, this embodiment provides a foundation pit warning protective guard, including fixed plate 1 and warning sign 12, warning sign 12 is installed at the upper surface of fixed plate 1, and the ring channel has been seted up to the inside of fixed plate 1, and the internally mounted of ring channel has filter screen 2, has good effect of blockking, can alleviate the weight of fixed plate 1 simultaneously, facilitates the transport and uses. The left end and the right end of the upper surface of the fixing plate 1 are fixedly connected with handles 11, and a rubber layer is sleeved at the handle of each handle 11. The outer ring of the fixed plate 1 is hinged with support rods 3 which are arranged at equal intervals through pin shafts 13, and the pin shafts 13 are spring pins. The bottom surface of fixed plate 1 is installed and is just reversing motor 4, and the rotation cycle of just reversing motor 4 is for making slider 6 move the distance value to the bottom from 5 tops of spout, and the accessible controller sets up. The output end of the forward and reverse rotation motor 4 is fixedly connected with a threaded rod 8, and the threaded rod 8 is inverted T-shaped, so that a threaded pipe 9 is prevented from being separated from the outer surface of the threaded rod 8. The surface cover of threaded rod 8 is equipped with threaded connection's screwed pipe 9, and the outer lane fixedly connected with linkage dish 7 of screwed pipe 9, and spout 5 has all been seted up to a side that every bracing piece 3 is close to threaded rod 8, and the equal joint in inside of every spout 5 has the slider 6 of looks adaptation, and every slider 6 all with the outer lane fixed connection of linkage dish 7.
