Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described below in combination with the embodiments.

[0041] See also Figure 1-Figure 5 In one embodiment of the present application, a safety flood prevention door for an urban underground garage includes a door frame 1 and a door body 5, wherein the door body 5 is movably arranged on the door frame 1, and a door groove 7 is formed on the door frame 1 to slide with the door body 5, and a signal transmitter 8 is arranged on the door frame 1. The safety flood prevention door also includes:

[0042] The airbag 6 is arranged in the door body 5, and a sealing groove 23 matching the shape of the airbag 6 is arranged in the door frame 1;

[0043] Release components, which are in two groups and are symmetrically arranged on the door frame 1, and are connected to the door body 5, and are used to release the door body 5 and control the door body 5 to decelerate; and

[0044] The monitoring module, which is at least one group and is arranged on the door frame 1, is used to monitor the ground water level; wherein

[0045] Each set of release components includes:

[0046] A deceleration structure is arranged between the door body 5 and the door frame 1, and the door body 5 is decelerated by the deceleration structure when moving along the door groove 7;

[0047] An inflation module, which is disposed on the door body 5 and connected to the deceleration structure, and inflates the airbag 6 through the inflation module when the deceleration structure is working; and

[0048] The locking structure is arranged on the door frame 1 and connected to the door body 5, and is used to fix the position of the door body 5. The locking structure is electrically connected to the monitoring module.

[0049] In a specific case of this embodiment, the deceleration structure includes:

[0050] A winding reel 11 is movably arranged on the door body 5 and slidably cooperates with the door frame 1;

[0051] A fixed tube 24 is provided on the door body 5; and

[0052] The piston 25 is movably disposed in the fixed tube 24 and the two are elastically connected. The winding drum 11 is connected to the piston 25 via a steel rope 12 .

[0053] In another specific case of this embodiment, the inflation module includes:

[0054] The air box 14 is arranged on the door body 5, the air extraction cavity formed in the air box 14 is connected to the fixed pipe 24, the air box 14 is formed with a first cavity 15 and a second cavity 17, the first cavity 15 is connected to the air extraction cavity, and the second cavity 17 is connected to the air bag 6;

[0055] A first slide plate 16 is movably disposed in the first cavity 15; and

[0056] The second slide plate 18 is movably arranged in the second cavity 17 and the two are connected by an elastic member, and the first slide plate 16 and the second slide plate 18 are connected by a connecting rod.

[0057] It should be noted that the elastic member can be replaced by a spring 19, a spring sheet or an elastic steel plate structure. In the present embodiment, the elastic member is preferably a spring 19, and the spring 19 is connected between the No. 2 slide 18 and the No. 2 cavity 17. As for the specific model of the spring 19, the best choice can be made according to the actual situation, and no specific limitation is made here.

[0058] When the road surface is flooded due to rainy weather, the monitoring module automatically controls the locking structure to release the door body 5 after detecting the existence of the flood phenomenon. At this time, under the action of the gravity of the door body 5, the door body 5 moves down along the door slot 7. In this process, the friction resistance between the winding drum 11 and the door frame 1 can be used to drive the winding drum 11 to rotate, thereby winding the steel rope 12 and driving the piston 25 to move along the fixed tube 24, so that under the action of the elastic force between the fixed tube 24 and the piston 25, the winding drum 11 is prevented from rotating. At this time, the friction resistance between the winding drum 11 and the door frame 1 is used to achieve the deceleration work of the door body 5 when it falls, so as to avoid the door body 5 from falling quickly and causing an accident, and when the piston 25 During the movement along the fixed tube 24, the air in the air extraction cavity can be extracted, so that under the action of negative pressure, the No. 1 slide 16 and the No. 2 slide 18 move downward relative to the air box 14, thereby squeezing the air in the No. 2 cavity 17 into the airbag 6, causing the airbag 6 to expand and eventually fill the sealing groove 23, completing the release of the door body 5 to block the flood from entering the parking lot. The entire device has a high degree of automation, which can not only automatically monitor the occurrence of road flooding and automatically control the release of the door body 5, but also the release speed of the door body 5 is slow and safe. At the same time, compared with traditional flood control doors, the sealing performance of the device is better, and it is not easy for some floods to pass through the gaps into the parking lot.

[0059] See also Figure 1 as well as Figure 2 , as another preferred embodiment of the present application, the locking structure includes a locking rod 9 and a group of electromagnets 13;

[0060] The locking rod 9 is movably arranged on the door frame 1 and the two are elastically connected. A locking groove 10 for inserting the locking rod 9 is formed on the door body 5. Electromagnets are arranged on the opposite surfaces of the locking rod 9 and the door frame 1. The electromagnet 13 is electrically connected to the monitoring module.

[0061] In this exemplary embodiment, the monitoring module includes a monitoring box 2 and a humidity sensor 4 . The monitoring box 2 is disposed on the door frame 1 . A water inlet 3 is disposed on the monitoring box 2 . The humidity sensor 4 is disposed inside the monitoring box 2 .

[0062] It should be noted that the present embodiment is not limited to the above-mentioned electromagnet 13 to adjust the position of the locking rod 9, and a linear motor or an electric cylinder may be used instead, which are not listed here one by one.

[0063] When there is flooding on the road surface, the flood enters the monitoring box 2 through the water inlet 3, and the humidity sensor 4 detects the water level rise and controls the electromagnet 13 to be energized and attracted, thereby driving the locking rod 9 to move. Figure 2 The door body 5 moves leftward in the direction shown, and the locking rod 9 disengages from the locking groove 10, so that under the action of the gravity of the door body 5, the door body 5 is automatically released to perform flood prevention and isolation work.

[0064] See also Figure 1 , Figure 4 as well as Figure 5 As another preferred embodiment of the present application, the safety flood control door also includes a detection module, which is arranged on the door body 5 and is used to detect the water pressure value of the ground water on the door body 5.

[0065] In this exemplary embodiment, the detection module includes:

[0066] The detection plate 20 is movably arranged in the detection groove formed on the door body 5 and the two are elastically connected;

[0067] A conductive ring 21 is provided on the detection board 20; and

[0068] The resistance bar 22 is disposed on the door body 5 and is located on the moving path of the conductive ring 21 .

[0069] It should be noted that this embodiment is not limited to the above-mentioned conductive ring 21 and resistor bar 22 to monitor the position of the detection plate 20 in the detection slot, and infrared ranging sensors or ultrasonic ranging sensors can also be used instead, which are not listed here one by one.

[0070] When water accumulates on the road due to rainy weather, the detection plate 20 can be squeezed under the action of water pressure, so that the detection plate 20 and the conductive ring 21 can move relative to the detection groove. According to the size of the water pressure, the conductive ring 21 can be made to contact different positions on the resistor bar 22, and the pressure information is transmitted to the staff's mobile terminal through the signal transmitter 8 through the resistance value of the access circuit, so that the flood control staff can detect the intensity of the flood on the road and take treatment measures.

[0071] How this application works:

[0072] When the road is flooded due to rainy weather, the flood enters the monitoring box 2 through the water inlet 3, and the humidity sensor 4 detects the water level rise and controls the electromagnet 13 to be energized and attracted, thereby driving the locking rod 9 to move. Figure 2 The door 5 moves leftward in the direction shown, and the locking rod 9 disengages from the locking groove 10, so that under the gravity of the door body 5, the door body 5 is automatically released to perform flood control and isolation work. At this time, under the gravity of the door body 5, the door body 5 moves down along the door groove 7. In this process, the friction resistance between the winding disk 11 and the door frame 1 can be used to drive the winding disk 11 to rotate, thereby winding the steel rope 12 and driving the piston 25 to move along the fixed tube 24, so that under the elastic force between the fixed tube 24 and the piston 25, the winding disk 11 is prevented from rotating. At this time, the friction resistance between the winding disk 11 and the door frame 1 is used to achieve the deceleration work of the door body 5 when it falls, so as to avoid the door body 5 from falling rapidly and causing an accident, and in the process of the piston 25 moving along the fixed tube 24, the air in the suction chamber can be sucked out, so that under the action of negative pressure, the No. 1 slide 16 and the No. 2 slide 1 8 moves downward relative to the air box 14, thereby squeezing the air in the second cavity 17 into the airbag 6, so that the airbag 6 expands and finally fills the sealing groove 23, completing the release of the door body 5 to block the flood from entering the parking lot. When there is water accumulation on the road surface due to rainy weather, the detection plate 20 can be squeezed under the action of water pressure, so that the detection plate 20 and the conductive ring 21 move relative to the detection groove, so that according to the size of the water pressure, the conductive ring 21 can contact different positions on the resistor bar 22, and the pressure information is transmitted to the mobile terminal of the staff through the signal transmitter 8 through the resistance value of the access circuit, so that the flood control staff can detect the intensity of the road flood and take treatment measures. The whole device has a high degree of automation, which can not only automatically monitor the occurrence of road flooding and automatically control the release of the door body 5, but also the release speed of the door body 5 is slow and safe. At the same time, compared with the traditional flood control door, the sealing performance of this device is better, and it is not easy for some floods to enter the parking lot through the gap.

[0073] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
