Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The specific embodiment is as follows:

example 1

As shown in fig. 1, a wind kiosk flood prevention system includes a wind shaft 1 communicated with an underground space, a wind gap 2 arranged on a left side wall of the wind shaft 1 for ventilation, a track 3 arranged on an inner side of the left side wall of the wind shaft 1, and a flood prevention baffle 4 slidably arranged on the track 3, wherein the flood prevention baffle 4 is used for sealing the wind gap 2. And a sealing strip 8 is arranged on the inner side of the left side wall of the air shaft 1 along the edge of the ventilation opening 2.

The wind box is commonly used for connecting the underground space and the ground, as shown in fig. 2, the air on the ground flows into the wind shaft 1 through the wind opening 2 and then flows to the underground space, so that the ventilation of the inside is facilitated. However, when inland inundation occurs in a city, a large amount of water may be generated on the ground, and when the height of the water rises to the height of the tuyere 2, the water may enter the air shaft 1 through the tuyere 2 and then flow to the underground space, and when the amount of water is too much, damage may be caused to facilities inside the underground space. In order to avoid this phenomenon, this embodiment is in 2 belows in wind gap set up flood baffle 4, when surface ponding, go up the upglide the flood baffle 4, through flood baffle 4 will wind gap 2 shelters from for the ponding on ground can't be followed wind gap 2 gets into in the air shaft 1, can avoid ponding to cause the harm to underground space inner facilities.

In this embodiment, along 2 edges in wind gap set up sealing strip 8, when flood prevention baffle 4 covers wind gap 2 department, flood prevention baffle 4 can with sealing strip 8 in close contact with, it is more tight to cover like this, can avoid ponding to flow into inside from the gap.

When the ground area is excessively watered, the accumulated water outside can generate larger pressure on the flooding-proof baffle 4 and even push the flooding-proof baffle 4 away, so as to avoid the phenomenon. In this embodiment, as shown in fig. 2, the wind shaft further includes a pressing device 5 disposed in the wind shaft 1 for pressing and fixing the flood baffle 4. The pressing device 5 presses the flood-proof baffle 4, so that the flood-proof baffle 4 is prevented from being pushed away by accumulated water.

As shown in fig. 3, the pressing device 5 includes a screw 501 fixedly installed on the inner side of the left side wall of the air shaft 1, and a pressing plate 502 for pressing the flood baffle 4, the pressing plate 502 is provided with a screw hole adapted to the screw 501, and the pressing plate 502 is screwed with the screw 501 through the screw hole. When the flood-proof baffle 4 slides up to cover the air inlet 2, the pressing plate 502 is rotated to move leftwards, so that the flood-proof baffle 4 is pressed against the left side wall of the air shaft 1, and the stability of the flood-proof baffle 4 is enhanced.

In this embodiment, as shown in fig. 4, four sets of pressing devices 5 are disposed on the inner side of the left sidewall of the air shaft 1. The four groups of the pressing devices 5 are distributed at four corners of the tuyere 2. When the flood-proof baffle 4 is moved to cover the air inlet 2, four groups of the pressing devices 5 can be adjusted at the same time, so that four corners of the flood-proof baffle 4 are pressed, and the stability of the flood-proof baffle 4 is further improved.

In order to push the flood baffle 4 to move up and down, manual operation can be adopted, namely, a worker pushes the flood baffle 4 to slide up and down inside the air shaft 1 through manpower, and then the air port 2 is shielded. However, the manual operation mode is time-consuming and labor-consuming, and the efficiency is low, so that the urban waterlogging cannot be dealt with in time. In order to rapidly drive the flood baffle 4 to slide up and down, in this embodiment, as shown in fig. 4, a driving device 6 is further included, which is disposed inside the left sidewall of the wind shaft 1 and is used for driving the flood baffle 4 to slide up and down.

Specifically, the driving device 6 includes a driving wheel 601, a driven wheel 602 and a stepping motor 605, the driving wheel 601, the driven wheel 602 and the stepping motor 605 are arranged on the inner side of the left side wall of the air shaft 1, the driving wheel 601 is in transmission connection with the driven wheel 602 through a conveying belt 603, and the conveying belt 603 is connected with the flood prevention baffle 4 through a connecting rod 604.

The driving wheel 601 is driven to rotate by the stepping motor 605, so that the conveying belt 603 drives up and down to drive the connecting rod 604 to move up and down, and further drive the flood-proof baffle 4 to slide up and down, and the opening and closing of the air port 2 can be quickly realized.

In some other embodiments, the air port 2 can be opened and closed by an air cylinder, the power output end of the air cylinder is fixedly connected with the flooding-proof baffle 4, and the air cylinder drives the flooding-proof baffle 4 to move up and down, so that the air port 2 can be opened and closed quickly.

Finally, in order to achieve an automatic closure management, i.e. when water is accumulated on the ground, the tuyere 2 can be closed automatically. In this embodiment, the outer side of the left side wall of the air shaft 1 is provided with an automatic control device 7, the automatic control device 7 comprises a liquid level sensor 701 and a PLC single chip microcomputer 702 which are arranged on the outer side of the left side wall of the air shaft 1, the liquid level sensor 701 is electrically connected with the PLC single chip microcomputer 702, and the PLC single chip microcomputer 702 is electrically connected with the stepping motor 605.

The liquid level sensor 701 can monitor accumulated water on the ground in real time, when the height of the accumulated water reaches the height of the air port 2, the liquid level sensor 701 transmits a starting signal to the PLC single chip microcomputer 702, the PLC single chip microcomputer 702 receives the starting signal and then transmits a starting instruction to the stepping motor 605, the stepping motor 605 drives the driving wheel 601 to rotate to drive the flooding-prevention baffle 4 to slide upwards for a certain distance, and the flooding-prevention baffle 4 immediately seals the air port 2; when the height of the accumulated water is lower than that of the air port 2, the liquid level sensor 701 transmits a closing signal to the PLC single chip microcomputer 702, the PLC single chip microcomputer 702 receives the closing signal and then transmits a closing instruction to the stepping motor 605, the stepping motor 605 drives the driving wheel 601 to rotate reversely, the flooding-prevention baffle 4 is driven to slide downwards for a certain distance, and the air port 2 is opened.

The switch 703 is arranged on the outer side of the left side wall of the air shaft 1, and the switch 703 is electrically connected with the PLC single chip microcomputer 702. Similarly, after the switch 703 is turned on, a turn-on signal can be transmitted to the PLC single chip microcomputer 702, and after the switch 703 is turned off, a turn-off signal can be transmitted to the PLC single chip microcomputer 702, so that the manual quick control of the upward and downward sliding of the flood baffle 4 is realized.

In some other embodiments, an ultrasonic level meter may be used instead of the liquid level sensor 701, and the ultrasonic level meter may also detect the water level on the ground in time, so as to transmit a turn-on or turn-off signal to the PLC single chip 702.
