[0028] This specific embodiment is a flat steel gate with good sealing effect, and its structural schematic diagram is as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown in the figure, it includes a gantry 1 and a steel plate 7. A bottom block 10 is fixedly connected to the lower end of the gantry 1. A sealing assembly 2 is installed inside the bottom block 10. Two groups of symmetrically distributed insertion blocks 16 are installed on the upper surface of the bottom block 10. The upper ends of the insertion blocks 16 are circular-arc shaped. Two groups of symmetrically distributed clamping grooves 12 are provided at the lower part of the steel plate 7. The upper ends of the clamping grooves 12 are circular-arc shaped. An insertion plate 13 is installed at the center position of the lower surface of the steel plate 7. An extrusion groove 14 is opened at the center position of the lower part of the insertion plate 13. The clamping grooves 12 are in clamping fit with the insertion blocks 16. A threaded pipe 3 is installed on the upper surface of the gantry 1. A plurality of groups of symmetrically distributed side plates 6 are installed on both sides of the gantry 1. A screw rod 4 is threadedly penetrated through the center position of the upper surface of the gantry 1. The screw rod 4 is in threaded fit with the threaded pipe 3. The upper end of the screw rod 4 is connected to a turntable 5. The lower end of the screw rod 4 is rotatably connected to the steel plate 7. Two groups of symmetrically distributed limiting plates 8 are threadedly installed on the inner side walls of the gantry 1. The steel plate 7 is in sliding contact with the two groups of limiting plates 8. Two groups of symmetrically distributed T-shaped grooves 9 are opened at the middle position of the inner wall of the gantry 1. Two groups of symmetrically distributed T-shaped blocks 11 are provided on both sides of the steel plate 7. The T-shaped blocks 11 are in sliding fit with the T-shaped grooves 9. A drain port 15 is opened at the lower end of the side surface of the bottom block 10. When installing the steel gate through the side plates 6 and actually using this flat steel gate to seal the water body, rotate the turntable 5 to drive the screw rod 4 to rotate. The screw rod 4 rotates and moves downward along the threaded pipe 3. The screw rod 4 moves downward to drive the steel plate 7 to move downward. When the steel plate 7 moves downward, it is limited by the two groups of limiting plates 8. When the steel plate 7 moves downward, it drives the T-shaped blocks 11 to slide along the T-shaped grooves 9. When the insertion plate 13 at the lower end of the steel plate 7 contacts the sealing assembly 2, the insertion plate 13 abuts against the sealing assembly 2. The water flow inside the bottom block 10 is discharged through the drain port 15 provided on the side surface, preventing the spring 204 from being damaged due to being soaked in water for a long time and improving the service life of the spring 204.

[0029] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 6As shown in the figure, the sealing assembly 2 includes a spring 204. The lower end of the spring 204 is fixedly installed at the central position inside the bottom block 10. The upper end of the spring 204 is connected to a sealing block 201. The sealing block 201 is slidably adapted to the bottom block 10. A groove slidably adapted to the sealing block 201 is formed in the bottom block 10. A sealing groove 202 is formed in the bottom block 10. The lower end of the sealing groove 202 is circular-arc-shaped. A sealing strip 203 is installed at the central position of the lower part of the sealing groove 202. The cross-section of the sealing strip 203 is semi-circular. The sealing strip 203 is clamped and adapted to the extrusion groove 14. The insertion plate 13 is clamped and adapted to the sealing groove 202. When the insertion plate 13 moves downward to contact the sealing groove 202, and the extrusion groove 14 at the lower end of the insertion plate 13 is clamped tightly with the sealing strip 203, the sealing is completed. When the steel plate 7 drives the insertion plate 13 to move downward, the insertion block 16 is inserted into the card slot 12. When the insertion block 16 is completely inserted into the card slot 12, the sealing between the insertion block 16 and the card slot 12 is completed. And when the steel plate 7 drives the card slot 12 to move downward, the extrusion groove 14 presses the sealing block 201 downward. The sealing block 201 compresses the spring 204 downward. Under the elastic force of the spring 204, the extrusion groove 14 always presses tightly against the sealing strip 203.

[0030] Working principle: The steel gate is installed through the side plate 6. When actually using this flat steel gate to seal the water body, rotate the turntable 5 to drive the screw rod 4 to rotate. The screw rod 4 rotates and moves downward along the threaded pipe 3 (the threaded pipe 3 is threadedly connected to the screw rod 4. The threaded connection has a self-locking function, which can prevent the steel plate 7 from moving up and down, and the denser the thread, the better the self-locking property). The screw rod 4 moves downward to drive the steel plate 7 to move downward. When the steel plate 7 moves downward, it is limited by two sets of limit plates 8. When the steel plate 7 moves downward, it drives the T-shaped block 11 to slide along the T-shaped groove 9. Through the cooperation of the T-shaped block 11, there is no gap between the two sides of the steel plate 7 and the gantry 1, effectively preventing water flow from flowing out from both sides of the steel plate 7 and improving the sealing performance of the steel plate 7.

[0031] When the insertion plate 13 at the lower end of the steel plate 7 contacts the sealing assembly 2, the insertion plate 13 abuts tightly against the sealing assembly 2. Specifically, the insertion plate 13 moves downward to contact the sealing groove 202. When the extrusion groove 14 at the lower end of the insertion plate 13 is clamped with the sealing strip 203, the sealing is completed. When the steel plate 7 drives the insertion plate 13 to move downward, the insertion block 16 is inserted into the card slot 12. When the insertion block 16 is completely inserted into the card slot 12, the sealing between the insertion block 16 and the card slot 12 is completed. And when the steel plate 7 drives the card slot 12 to move downward, the extrusion groove 14 presses the sealing block 201 downward, and the sealing block 201 compresses the spring 204 downward. Under the elastic force of the spring 204, the extrusion groove 14 always abuts tightly against the sealing strip 203. Through the settings of the sealing assembly 2, the extrusion groove 14, and the insertion plate 13, the bottom plate of the steel plate 7 is sealed, preventing water flow through the gap at the bottom of the steel plate 7, and improving the sealing performance of the flat steel gate. Through the settings of the sealing assembly 2, the extrusion groove 14, the insertion plate 13, the card slot 12, and the insertion block 16, multi-layer sealing of the bottom of the steel plate 7 is achieved, and the sealing effect is good;

[0032] The water flow inside the bottom block 10 is discharged through the drain port 15 provided on the side, preventing the spring 204 from being damaged due to being soaked in water for a long time and improving the service life of the spring 204.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
