DETAILED DESCRIPTION

[0030] Embodiment 1, as Figure 1-Figure 4As shown, a flood-proof and water-blocking gate proposed by the present invention comprises a mounting frame 2, a door frame 1, a water flow metering component 6 and a flood-proof and water-blocking component 3. The mounting frame 2 is located on the walls on both sides of the passageway; the door frame 1 is installed between two groups of mounting frames 2 and is located above the passageway, and a downward-opening storage chamber is arranged inside the door frame 1; the water flow metering component 6 is installed between two groups of mounting frames 2 and is located below the passageway, and the flood warning situation is judged by measuring the amount of water entering the passageway; the flood-proof and water-blocking component 3 slides out of the storage chamber through the flood-proof and water-blocking component 3, and forms a flood-proof and water-blocking wall with the water flow metering component 6 and the door frame 1, and slides into the storage chamber through the flood-proof and water-blocking component 3, and forms a space for pedestrians and vehicles to pass through with the water flow metering component 6. The flood-proof and water-blocking assembly 3 is provided with a water-blocking and drainage component 306; the water-blocking and drainage component 306 is synchronously stretched or contracted by the horizontal movement of the movable plate 302 to adjust the internal pressure; when a flood occurs, the water-blocking and drainage component 306 absorbs water when the pressure is negative, and drains water when the pressure is positive; the water-blocking and drainage component 306 absorbs water and drains water, which, on the one hand, increases the weight for flood prevention, and on the other hand, drains water and prevents flooding; when a flood does not occur, the water-blocking and drainage component 306 is used for inhaling and exhaling air, which, on the one hand, is used to replace the air inside and outside the channel, and on the other hand, is used to buffer impact.

[0031] like Figure 4-Figure 6 As shown, the flood-proof water retaining assembly 3 includes a flood-proof water retaining frame 301; a water retaining and drainage component 306 is arranged on the flood-proof water retaining frame 301; a mounting seat 305 is arranged on the top of the flood-proof water retaining frame 301, slidably connected to the storage room, and connected to the lifting drive component 4 through a traction rope 7; a limit seat 307 is arranged at the bottom of the flood-proof water retaining frame 301, and cooperates with the water flow metering assembly 6; the movable plate 302 is located on both sides of the water retaining and drainage component 306, and is arranged parallel to the flood-proof water retaining frame 301.

[0032] By retracting the traction rope 7, the mounting seat 305 drives the flood prevention and water retaining frame 301 to move up and down, and controls the water retaining and drainage member 306 to enter and exit the storage room. When located in the storage room, the water retaining and drainage member 306 shrinks to reduce the volume, and when located outside the storage room, the water retaining and drainage member 306 works for flood prevention and water retaining, air replacement, or impact buffering.

[0033] The water retaining and drainage component 306 includes two groups of telescopic bags 30601 located between the flood-proof water retaining frame 301 and the movable plate 302; the two groups of telescopic bags 30601 are respectively located on the front and back sides of the flood-proof water retaining frame 301, and a water / air inlet pipe 30603 with a one-way valve is arranged at the bottom of each telescopic bag 30601; the water / air outlet pipe 30604 is arranged on the flood-proof water retaining frame 301, and is respectively connected to the tops of the telescopic bags 30601 on both sides.

[0034] It should be further explained that a double-headed bidirectional cylinder 304 is provided on the flood prevention and water retaining frame 301 to drive the movable plates 302 on both sides to move in opposite directions.

[0035] By horizontally moving the moving plate 302, the telescopic bag 30601 can be pulled to stretch or compress synchronously to adjust the internal pressure. Water / gas enters the telescopic bag 30601 from the water / gas inlet pipe 30603 and then is discharged from the water / gas outlet pipe 30604.

[0036] It should be further explained that the flood-proof and water-retaining frame 301 is provided with a through hole 30101 that connects the telescopic bags 30601 on both sides, so that the internal spaces of the two groups of telescopic bags 30601 are connected. A valve is provided on the through hole 30101; since the internal spaces of the two groups of telescopic bags 30601 are connected, the water or gas entering can be mixed. Water mixing can increase weight and increase its flood and water resistance effect. Water mixing and then discharging can transfer accumulated water and drain water to prevent waterlogging. Gas mixing can push the telescopic bags 30601 to swell, and buffer the impact of external forces when the moving plate 302 is hit. Gas mixing and then discharging can replace the air in the channel and improve the indoor environment.

[0037] like Figure 7 As shown, the water / gas outlet pipe 30604 includes a three-end through pipe 306041 located on the flood-proof water retaining frame 301; the two ends of the three-end through pipe 306041 respectively penetrate the two sides of the flood-proof water retaining frame 301, and are connected to the telescopic bag 30601 on the corresponding side through a one-way valve 2, and the other end is connected to the two-end through pipe 306043; the two-end through pipe 306043 is connected to the inner and outer spaces of the channel opening through the control valve 306042 respectively.

[0038] When draining, the end of the two-end through-tube 306043 connected to the outside is opened, and the water inside and outside the channel is transferred out through the external water pipe to achieve the purpose of flood prevention. When ventilating, the end of the two-end through-tube 306043 connected to the inside is opened to mix the air in the channel with the air outside the channel and then return it to the room to improve the indoor environment.

[0039] like Figure 8 As shown, the water flow metering assembly 6 includes a support seat 601 connected between the mounting frames 2; a plurality of metering spaces are separated inside the support seat 601 by a support plate 603, and water inlets and outlets 602 opposite to the metering spaces are arranged on the front and rear side walls; a mounting rod 604 connected to the support plate 603 is arranged in the metering space; a rotatable water flow velocity meter 605 is arranged on the mounting rod 604; and a water level monitor is also arranged in the metering space.

[0040] It should be further explained that a slag screen is provided on the water inlet and outlet 602 .

[0041] At the beginning of a flood, water flows into the metering space through the water inlet and outlet 602, driving the water flow velocity meter 605 to rotate, obtaining water flow velocity data, and the water level monitor to obtain water level data. The amount of water entering the channel is determined by combining the flow velocity and water depth. When the total water inflow exceeds the set threshold, the water retaining and drainage component 306 descends and starts. The setting of the threshold can be formulated in combination with the drainage capacity of the indoor drainage system.

[0042] like Fig. 9 As shown, a waterproof member 5 is arranged between the support seat 601 and the door frame 1; the waterproof member 5 comprises a waterproof strip 501 installed on the mounting frame 2; a water-absorbing and swelling resin layer 502 is arranged on the contact surface between the waterproof strip 501 and the flood-proof and water-retaining frame 301.

[0043] When the flood-proof water retaining frame 301 extends out of the door frame 1 and contacts with the waterproof strip 501, the resin layer 502 absorbs water and expands, thereby reducing the gap between the flood-proof water retaining frame 301 and the waterproof strip 501 and improving the sealing performance of the flood-proof water retaining wall.

[0044] like Fig.10 As shown, the limit seat 307 includes a cover body 30701 connected to the flood protection frame 301; the bottom groove shape of the cover body 30701 matches the support seat 601, and covers the water inlet and outlet 602 when it is lowered into place, and notches 30702 matching the shape of the waterproof strip 501 are set at both ends of the cover body 30701.

[0045] It should be further explained that the support seat 601 is set as a trapezoidal structure with a narrow top and a wide bottom, and the water inlet and outlet 602 are set on both sides thereof. The bottom groove of the cover body 30701 is provided with an inclined surface opposite to the water inlet and outlet 602, and a lighting lamp 30703 is provided on the top of the groove.

[0046] In daily work, the limit seat 307 is located above the support seat 601, and the lighting lamp 30703 can be used for lighting in the channel. During flood control and drainage, the cover body 30701 covers the support seat 601. The water inlet and outlet 602 are sealed, further enhancing the sealing of the flood control and water retaining wall.

[0047] like Fig.11 As shown, a mounting groove 101 is arranged on the opening of the storage chamber; electromagnets 102 and springs 103 are alternately arranged in the mounting groove 101, and a metal scraper frame 104 for acting on the moving plate 302 is arranged on the notch of the mounting groove 101.

[0048] After the flood control and water blocking are completed, mud and debris are attached to the movable plate 302. The electromagnet 102 is energized to generate magnetism, and the metal scraper frame 104 is sucked into the installation groove 101. When the movable plate 302 moves up to the top and faces the metal scraper frame 104, the electromagnet 102 is powered off. The metal scraper frame 104 pops up under the action of the spring 103 to clean the rising movable plate 302.

[0049] It should be further explained that a position sensor 303 associated with the electromagnet 102 is disposed on the movable plate 302 ; the electromagnet 102 determines the position of the movable plate 302 according to the position sensor 303 , and controls the metal scraper frame 104 to enter and exit the installation slot 101 .

[0050] Embodiment 2: Based on the flood control and water retaining gate in Embodiment 1, this embodiment proposes a flood control and water retaining method, and the specific steps are as follows:

[0051] S1, in the non-working state, the water retaining and drainage member 306 is located in the storage room;

[0052] S2, at the beginning of the flood, water flows into the metering space through the water inlet and outlet 602, driving the water flow velocity meter 605 to rotate, obtaining water flow velocity data, and the water level monitor obtains water level data;

[0053] S3, when the total water inflow exceeds the set threshold, the water retaining and drainage component 306 descends;

[0054] S4, the cover body 30701 covers the support seat 601, and the water inlet and outlet 602 are sealed; the resin layer 502 absorbs water and expands, reducing the gap between the flood-proof water retaining frame 301 and the waterproof strip 501;

[0055] S5, the moving plate 302 moves toward both sides, pulling the telescopic bag 30601 to stretch synchronously, water enters the telescopic bag 30601 from the water / air inlet pipe 30603 to increase the weight, and the flood-proof retaining wall works;

[0056] S6. After the flood stops rising, the movable plate 302 moves back and forth, and the two ends of the through pipe 306043 connected to the outside are opened, and connected to the drainage channel through the external water pipe. At the same time, the telescopic bag 30601 repeatedly inflows and outflows water to transfer the accumulated water inside and outside the channel to achieve the purpose of flood prevention;

[0057] S7. After flood prevention and water blocking is completed, the electromagnet 102 is energized to generate magnetism, and the metal scraper frame 104 is sucked into the installation groove 101. When the movable plate 302 moves up to the top and is opposite to the metal scraper frame 104, the electromagnet 102 is de-energized; the metal scraper frame 104 pops out under the action of the spring 103 to clean the rising movable plate 302.

[0058] Embodiment 3: Based on the flood control and water retaining gate in Embodiment 1, this embodiment proposes a ventilation method, and the specific steps are as follows:

[0059] The water retaining and drainage member 306 is located outside the storage room to block the passage;

[0060] The movable plate 302 moves back and forth, and one end of the two-end through-tube 306043 connected to the inside is opened, so that the air in the channel and the air outside the channel are sucked into the corresponding side of the telescopic bag 30601, and then returned to the room after mixing;

[0061] Repeat this process many times to improve the indoor environment.

[0062] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
