The specific working process of the invention is as follows: the device is divided into two states, the first state is a common municipal guard rail rod shape, the slide block 8 is arranged at the lowest end position at the moment, the slide block 8 is fixed at the position through a pin, the second pressure spring 9 is compressed and enables the slide block to have rebound tendency and elastic potential energy, the wedge block 10 is arranged at the upper end and the lower end of the rectangular frame 2 in the first sliding chute 7 at the moment and is limited, therefore, the rectangular frame 2 is kept in a vertical shape at the moment, simultaneously, the lower ends of a plurality of first vertical plates 3 are in contact with the ground, the compression of the first pressure springs 4 is realized under the extrusion of the ground, the first pressure springs 4 have the rebound tendency and the elastic potential energy, the first vertical plates 3 are extruded to enable the vertical plates to move upwards relative to the rectangular frame 2, at the moment, the upwards moving of the first vertical plates 3 drives two second vertical plates 5 at two sides to move outwards through the connecting rods 6, at the moment, the intervals between the two adjacent second vertical plates 5 and the second vertical plates 5 are kept the same with the first vertical plates 3, the device is a common municipal guard rail from the appearance.
When inland inundation occurs in a city, the pin for fixing the sliding block 8 is pulled out, the sliding block 8 is enabled to move upwards under the reset action of the second pressure spring 9, at the moment, the movement of the sliding block 8 drives the rectangular frame 2 to move upwards, in the process, the first vertical plate 3 and the second vertical plate 5 both move upwards along with the rectangular frame 2, in the process, the first vertical plate 3 has the tendency of gradually separating from the ground, but the lower end of the first vertical plate 3 moves downwards under the reset action of the first pressure spring 4, in the moving process, the first vertical plate 3 drives the two second vertical plates 5 at two sides to approach to the first vertical plate 3 through the connecting rod 6, meanwhile, the first vertical plate 3 and the second vertical plates 5 which are combined together under the action of the first pressure spring 4 are not easy to separate, in the process that the wedge block 10 extrudes the upper end groove wall of the first sliding groove 7 when the rectangular frame 2 moves upwards, and the wedge block 10 is separated from the first sliding groove 7, and slides in the first sliding groove 7 and is not separated from the first sliding groove 7, the gear 11 is engaged with the rack 14, at the moment, the front ends of the legs rotate forwards and are unfolded, and the legs are positioned under the limiting of the limiting blocks 12 and the arc-shaped grooves 21, the supporting legs 13 move in place when the wedge blocks 10 are separated from the first sliding grooves 7, along with the continuous upward movement of the rectangular frame 2, the upper ends of the square cylinders 19 contact and press the inclined rods 15, the upper ends of the rectangular frame 2 incline forwards under the guiding action of the inclined rods 15, the rectangular frame 2 is made to be horizontal under the action of the supporting legs 13, the sliding blocks 8 move to the positioning holes at the upper ends at the moment, the sliding blocks 8 are fixed at the positions under the limiting action of the pins, the rectangular frame 2 is kept in a horizontal state at the moment, meanwhile, each group of blocking supporting units is provided with three adjacent independent vertical plates to become a spliced wide plate, and the wide plate forms a channel on a water road surface to facilitate people to walk.
After urban inland inundation, can rotate rectangular frame 2 into vertical form to make each part restore to the guardrail state with this device again after reseing, reuse when waiting to inland inundation next time.
Compared with the traditional equipment, the device has the following advantages:
1. this device divide into two states, the first state is the guardrail state, a plurality of risers 3 and 5 interval arrangements of a plurality of risers, see with ordinary guardrail not have the difference under outward appearance and the effect, and can play the all functions of ordinary guardrail, can use the second state after urban waterlogging takes place, loosen the pin and make 2 upward movements of rectangle frame and convert the horizontality gradually, the first riser 3 of a plurality of interval equipartitions uses one with the riser 5 to block two risers 5 and draw close to one riser 3 as the benchmark with one of support element, gather into the wide board of an interval grow and board width widen with the riser of original equal, the face after the change is fit for people's walking and the face distance of change is fit for the step width of walking, make this device of change accord with the human engineering principle, make the walking safer.
2. This device clamps and slidable in first spout 7 through wedge 10, when making the guardrail state, can the effectual vertical state who guarantees rectangular frame 2, under the effect of pin of not pulling out, wedge 10 can not be removed, make whole device more stable, when using the second state, wedge 10 slides the in-process in first spout 7, for gear 11 and the meshing of rack 14 provide limiting displacement, make rack 14 drive gear 11 rotate and overcome the resistance that gear 11 rotated the in-process, make landing leg 13 can high-efficient quick rotation target in place, make things convenient for the quick transform of this device.
3. Because this device goes upward power and comes from the reseing of second pressure spring 9, consequently rectangle frame 2 goes upward to be an ejection state, consequently it all has probably with backward rotation to rotate in place the back rectangle frame 2 upper end at landing leg 13, if the slope of rectangle frame 2 upper end is backward then this device can not be used, consequently, set up down tube 15, break away from behind first spout 7 wedge 10 and can make square pipe and down tube 15 contact, the upper end that realizes rectangle frame 2 under the guide effect of down tube 15 can guarantee the slope of inclining to the front side, make this device use more intelligent.
The urban waterlogging monitoring device is novel in concept, ingenious in structure and high in practicability, and effectively solves the problem that people are inconvenient to go out when urban waterlogging occurs at the present stage.
