The foam sealing pad 5 can improve the water-retaining sealing performance. The airbag cushion 6 connected in the middle contains gas. When the water flow applies pressure, the foam sealing pad 5 squeezes the airbag cushion 6, causing the airbag cushion 6 to deform and expand toward the side of the support plate 1. The expanded area will fill the joint between the support plate 1 and the channel, increase the sealing performance of the support plate 1, and improve its water-retaining performance.

[0040] Working principle: When the device is used, first place the device in the channel where water needs to be blocked, place the water retaining plate 4 on the side where water needs to be blocked, and insert the device vertically into the channel; The driving motor 18 is started, and the driving motor 18 drives the driving rod 19 to rotate, the driving rod 19 drives the worm 20 to rotate, the worm 20 drives the driving screw 12 to rotate, the driving screw 12 drives the driving plate 11 to move downward, and the driving plate 11 drives the two primary reinforcement feet 3 to move downward, so that the two primary reinforcement feet 3 are inserted into the soil of the channel through the cone feet 25 to reinforce the support plate 1.

At the same time, the connecting rod 32 drives the second-stage gear 35 to rotate, and the second-stage gear 35 drives the second-stage stabilizing foot 34 and the fourth-stage stabilizing foot 37 to move at the same time, so that the second-stage stabilizing foot 34 and the fourth-stage stabilizing foot 37 extend out of the outside of the first-stage reinforcement foot 3. By inserting the first-stage stabilizing foot 27, the second-stage stabilizing foot 34, the third-stage stabilizing foot 36 and the fourth-stage stabilizing foot 37 into the soil, the contact area between the first-stage reinforcement foot 3 and the soil is increased, thereby increasing the supporting stability of the two first-stage reinforcement feet 3. At the same time, the worm wheel 17 drives the worm 20 to rotate, the worm 20 drives the two retracting screws 15 to rotate, the two retracting screws 15 respectively drive the two limit blocks 21 to move away from each other, and the two limit blocks 21 respectively drive the two secondary reinforcement feet 9 to move away from each other, so that the two secondary reinforcement feet 9 are respectively inserted into the soil on both sides of the channel to reinforce and support both sides of the support plate 1; During the rotation of the two retractable screw rods 15, the two rotating rods 7 are respectively driven to rotate, and the two rotating rods 7 drive the same reinforcement plate 2 to move, and the reinforcement plate 2 drives the support rod 8 to move. During the movement, the mounting plate 39 is driven to move through the gear rod 40, and the mounting plate 39 drives the stabilizing cone 38 to move to the outside of the reinforcement plate 2, so that the stabilizing cone 38 extends out of the outside of the reinforcement plate 2, and the stabilizing cone 38 is inserted into the soil to fix the support plate 1, so that the support plate 1 is stabilized and reinforced by the two rotating rods 7 and the two support rods 8; During the water blocking process, the water pressure of the water flow will squeeze the water baffle 4, and the water baffle 4 will drive the foam sealing pad 5 to squeeze the airbag cushion 6, causing the airbag cushion 6 to deform and expand toward the side of the support plate 1. The expanded area will fill the joint between the support plate 1 and the channel, thereby increasing the sealing of the support plate 1 and improving its water blocking performance.
