[0009] The telescopic elements are the same number as the sliding seats, and the telescopic elements are connected between the foundation and the sliding seats;

[0010] A pop-out structure, located on the main door and connected between the two sub-doors, is used to control the two sub-doors to pop out from the storage slot; and

[0011] The monitoring system, installed between the foundation and the main gate, is used to monitor flood occurrences and control the operation of expansion joints;

[0012] The monitoring system includes:

[0013] There must be at least one water inlet pipe, which must be installed within the foundation.

[0014] The rotating blade is movable inside the water inlet pipe;

[0015] A locking assembly, positioned between the rotary leaf and the main door body, is used to fix the position of the main door body; and

[0016] The monitoring module, installed on the inlet pipe and connected to the main blade, is used to monitor the water flow speed in the inlet pipe and control the operation of the telescopic element.

[0017] A further technical solution of this application is: a resistance-reducing component is provided between the door body and the storage tank to reduce the frictional resistance between the door body and the storage tank.

[0018] A further technical solution of this application: the locking component includes:

[0019] The fixed box is installed within the foundation;

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.

[0046] Please see Figures 1-5 In one embodiment of this application, an urban emergency concealed floodgate includes a foundation 1 and a floodgate body. The floodgate body is movably inserted into the foundation 1. The floodgate body has an expandable structure. The floodgate body includes a main gate body 2 and two sub-gate bodies 6. The sub-gate bodies 6 are symmetrically arranged relative to the main gate body 2. The main gate body 2 has a storage groove 10 formed on it for storing the sub-gate bodies 6. The floodgate also includes:

[0047] Sliding seats 4, in a set and symmetrically movable within the foundation 1, are movably connected to the main door body 2 via push arms 5;

[0048] The telescopic elements are the same number as the sliding seats 4, and the telescopic elements are connected between the foundation 1 and the sliding seats 4;

[0049] A pop-out structure, mounted on the main door body 2 and connected between the two sub-door bodies 6, is used to control the two sub-door bodies 6 to pop out from the storage slot 10; and

[0050] The monitoring system, located between foundation 1 and main gate 2, is used to monitor flood occurrences and control the operation of expansion joints;

[0051] The monitoring system includes:

[0052] Water inlet pipe 16, at least one in number, is installed within the foundation 1;

[0053] The rotating blade 17 is movably installed inside the water inlet pipe 16;

[0054] A locking assembly, disposed between the rotating leaf 17 and the main door body 2, is used to fix the position of the main door body 2; and

[0055] The monitoring module is installed on the inlet pipe 16 and connected to the main blade. It is used to monitor the water flow speed in the inlet pipe 16 and control the operation of the telescopic element.

[0056] It should be noted that the telescopic element can be replaced by a linear motor, electric cylinder, or pneumatic cylinder. In this embodiment, the telescopic element is preferably an electric telescopic rod 3, which is disposed between the foundation 1 and the sliding seat 4. The specific model parameters of the electric telescopic rod 3 can be optimally selected according to the actual situation, and are not specifically limited here.

[0057] In this embodiment, for example, a resistance-reducing component is provided between the door body 6 and the storage tank 10 to reduce the frictional resistance between the door body 6 and the storage tank 10.

[0058] Non-limiting, the drag-reducing component can be a ball or a roller 15. In this embodiment, the drag-reducing component is preferably a roller 15, which is movably disposed on the door body 6 and slides in cooperation with the storage groove 10.

[0059] In the event of a flood, the floodwater enters the city's drainage system through the inlet pipe 16. The floodwater causes the rotating blade 17 to rotate, thereby controlling the locking component to work and allowing the locking component to release its restriction on the main gate body 2. When the monitoring module detects that the flood intensity has reached the expected value, the monitoring module works and controls the electric telescopic rod 3 to retract, driving the sliding seat 4 to move. Under the action of the push arm 5, the main gate body 2 and the sub-gate body 6 are moved upward. When the main gate body 2 moves to the set position, the sub-gate body 6 is released from the restriction of its position by the foundation 1, and under the action of the pop-out structure, the sub-gate body 6 is popped out from the main gate body 2, thereby completing the expansion of the flood gate body and completing the flood blocking work.

[0060] Please see Figure 1 , Figure 3 , Figure 4 as well as Figure 5 In another preferred embodiment of this application, the locking component includes:

[0061] The fixed box is installed within foundation 1;

[0062] Locking rod 18 is movably mounted on the fixed box and the two are threaded together; the main door body 2 is formed with locking hole 19 for the locking rod 18 to be inserted; and

[0063] The locking shaft 20 is movably mounted on the water inlet pipe 16 and coaxially connected to the rotating blade 17. The locking rod 18 has a groove formed inside for inserting the locking mechanism.

[0064] In this embodiment, the monitoring module includes, for example:

[0065] Monitoring box 23 is installed on water inlet pipe 16;

[0066] The rotating rod 24 is movably installed inside the monitoring box 23 and coaxially connected to the rotating blade 17;

[0067] The counterweight 25 is movably set in the guide rail formed on the rotating rod 24 and the two are elastically connected.

[0068] Contact number 26 is located on counterweight 25; and

[0069] The second contact 27 is located on the rotating rod 24 and on the moving path of the first contact 26.

[0070] It should be noted that this embodiment is not limited to the method of monitoring the position of the counterweight 25 in the guide rail by the first contact 26 and the second contact 27 mentioned above. Infrared ranging sensors or laser ranging sensors can also be used instead, which will not be listed here.

[0071] When there is water accumulation on the surface of foundation 1, the water flows into the urban drainage system through the inlet pipe 16. During this process, the water can drive the rotating blade 17 to rotate. When the rotating blade 17 rotates, it drives the locking shaft 20 to rotate. The locking shaft 20 drives the locking rod 18 to rotate synchronously. Under the action of the threaded engagement between the locking rod 18 and the fixed box, the threaded rod is driven to disengage from the locking hole 19 to prepare for flood control measures. When a flood occurs, the water flow speed increases, causing the rotating blade 17 to rotate at high speed. At this time, the rotating rod 24 rotates synchronously. Under the action of centrifugal force, the counterweight moves along the guide rail towards the outside of the rotating rod 24 until the first contact 26 and the second contact 27 make contact. At this time, the electric telescopic rod 3 is triggered to retract, controlling the main body of the flood gate to rise from the foundation 1 to carry out flood control work.

[0072] Please see Figures 1-3 In another preferred embodiment of this application, the pop-out structure includes an intermediate tube 12, a drive arm 11, a piston rod 13, and an elastic element;

[0073] There are two drive arms 11, and the two gate bodies 6 are movably connected by the two drive arms 11. The intermediate tube 12 is arranged between the two drive arms 11. Each drive arm 11 is provided with a piston rod 13, which is movably inserted into the intermediate tube 12. Adjacent piston rods 13 are connected by elastic members.

[0074] In one specific embodiment, the monitoring system further includes an alarm module, which is located between the fixed box and the gate body 6. When the rotating blade 17 rotates, the alarm module is controlled to work to warn pedestrians and vehicles.

[0075] In another specific embodiment, the warning module includes:

[0076] Warning light 8 is installed in the light groove 7 formed on the door body 6;

[0077] A transparent cover 9 is installed on the light trough 7;

[0078] Conductive rod 21 is mounted on the retaining shaft 20; and

[0079] A conductive block 22 is mounted on a fixed box and is located on the moving path of the conductive rod 21. The conductive block 22, the conductive rod 21, and the warning light 8 are electrically connected.

[0080] It should be noted that the elastic element can be a spring 14, a spring sheet, or an elastic steel plate structure. In this embodiment, the elastic element is preferably a spring 14, which is connected between two adjacent piston rods 13. The specific model parameters of the spring 14 are not specifically limited here.

[0081] When the main gate 2 moves the secondary gate 6 upward and breaks free from the restriction of the secondary gate 6 position by the foundation 1, the elastic restoring force of the spring 14 can spring the piston rod 13 apart. Thus, under the action of the drive arm 11, the secondary gate 6 can be ejected from the storage slot 10 on the main gate 2, thereby completing the unfolding of the entire floodgate body. When the rotating blade 17 rotates, it can drive the roller 15 to rotate synchronously through the locking shaft 20, thereby driving the rotating rod 24 to rotate and intermittently contact the conductive block 22, controlling the warning light 8 to continuously flash, thereby completing the warning work for pedestrians and vehicles, and preventing pedestrians or vehicles from passing by when the floodgate body rises from the foundation 1.

[0082] How this application works:

[0083] When water accumulates on the surface of foundation 1, it flows into the urban drainage system through inlet pipe 16. During this process, the water drives the rotating blade 17 to rotate, which in turn drives the locking shaft 20 to rotate. The locking shaft 20 then drives the locking rod 18 to rotate synchronously. Under the threaded engagement between the locking rod 18 and the fixed box, the threaded rod disengages from the locking hole 19 to prepare for flood control measures. When a flood occurs, the increased water flow speed causes the rotating blade 17 to rotate at high speed, which in turn drives the rotating rod 24 to rotate synchronously. Under centrifugal force, the counterweight moves along the guide rail towards the outside of the rotating rod 24 until contact is made between contact point 26 and contact point 27. This triggers the retraction of the electric telescopic rod 3, causing the sliding seat 4 to move, thereby... Under the action of the push arm 5, the main gate body 2 and the sub-gate body 6 are moved upward. When the main gate body 2 moves the sub-gate body 6 upward and is freed from the restriction of the sub-gate body 6 position by the foundation 1, the piston rod 13 can be popped apart under the elastic restoring force of the spring 14. Thus, under the action of the drive arm 11, the sub-gate body 6 can be popped out from the storage groove 10 on the main gate body 2, thereby completing the unfolding of the entire flood control gate body. When the rotating blade 17 rotates, it can drive the roller 15 to rotate synchronously through the locking shaft 20, thereby driving the rotating rod 24 to rotate and intermittently contact the conductive block 22, controlling the warning light 8 to continuously flash, thereby completing the warning work for pedestrians and vehicles, and preventing pedestrians or vehicles from passing by when the flood control gate body rises from the foundation 1.
