[0002] The lifting water stop door is a facility for flood prevention, flood control, and flood protection. It is used at the entrances or ventilation openings of buildings in low-lying areas, underground garages, warehouses, subway entrances, substations, machine rooms, power distribution rooms, etc. It closes and drops during heavy rain to prevent rainwater backflow or flood intrusion.

[0003] The lifting water stop door includes an outer frame body, a door body, a lifting drive system, and a control system. The outer frame body includes a column bottom plate. The lifting drive system includes a guide rail system and a drive system. The control system includes an integrated water level sensor, rainfall monitoring, a remote control module, and is equipped with an emergency power supply. During use, the control system transmits and controls signals to control the drive system to work and control the vertical lifting of the door body under the guidance of the guide rail system. Among them, the door body is usually made of high-strength and corrosion-resistant materials, and the edge of the door body is equipped with a sealing strip (such as rubber or silicone) to ensure close fit with the ground or wall when closed to prevent leakage. However, the sealing effect of this single sealing strip structure still needs to be improved.

[0027] Refer to Figures 1-6, when in use, this device is installed at the sealed use position. When the lifting water stop gate descends and downwardly squeezes one end of the transmission pressure rod 11, the other end of the transmission pressure rod 11 rotates downward on the positioning plate 12 with the connecting bolt I121 as the rotation axis. At the same time, the middle position of the transmission pressure rod 11 pulls the main connecting plate 10 downward. The main connecting plate 10 pulls the sliding shaft 5 to vertically slide downward in the positioning guide block 4. The sliding shaft 5 drives the sub-connecting plate A8 and the sub-connecting plate B9 to move obliquely outward and downward. At the same time, the sliding shaft 5 drives the reset spring 61 downward to be extruded against the positioning guide block 4. The sub-connecting plate A8 and the sub-connecting plate B9 drive the sealing pressing plate 7 to move obliquely outward and downward simultaneously under the action of the guiding waist holes. The movement of the sealing pressing plate 7 drives the sealing assembly to move obliquely outward and downward. Specifically, the rubber strip pressing plate 15, the sealing rubber part A16, and the sealing rubber part B17 are extruded and move obliquely outward and downward with the sealing pressing plate 7. The sealing rubber part A16 and the sealing rubber part B17 are extruded at the position where the water stop gate needs to be sealed, so as to achieve sealing while the lifting water stop gate falls; When the lifting water stop gate rises and leaves the transmission pressure rod 11 without squeezing one end of the transmission pressure rod 11, under the reset action of the reset spring 61, one end of the reset spring 61 pushes the sliding shaft 5 upward. The transmission pressure rod 11 moves upward. The other end of the transmission pressure rod 11 rotates upward on the positioning plate 12 with the connecting bolt I121 as the rotation axis. At the same time, the middle position of the transmission pressure rod 11 pushes the main connecting plate 10 upward. The main connecting plate 10 pushes the sliding shaft 5 to vertically slide upward in the positioning guide block 4. At the same time, the sliding shaft 5 drives the sub-connecting plate A8 and the sub-connecting plate B9 to move obliquely inward and upward. The sub-connecting plate A8 and the sub-connecting plate B9 drive the sealing pressing plate 7 to move obliquely inward and upward simultaneously under the action of the guiding waist holes. The movement of the sealing pressing plate 7 drives the sealing assembly to move obliquely inward and upward. Specifically, the rubber strip pressing plate 15, the sealing rubber part A16, and the sealing rubber part B17 are extruded and move obliquely inward and upward with the sealing pressing plate 7. The sealing rubber part A16 and the sealing rubber part B17 leave the water stop plate, so that the water stop plate is lifted and the seal is released at the same time.

[0028] The principle is that there is a sealing rubber part A16 between the sealing pressing plate 7 and the positioning bottom plate. The cross-section of the sealing rubber part A16 is triangular or circular or other shapes. The sealing rubber part A16 and the sealing rubber part B17 are fixed on the positioning bottom plate through the rubber strip pressing plate 15. When the sealing pressing plate 7 moves, a positive gain effect is formed between its sealing surface and the rubber extrusion part A162 and the rubber extrusion part B172, so as to ensure sealing.

[0029] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
