[0044] In the embodiment, the transmission assembly comprises a top block 23, a second vertical slot 24, a first sliding slot 25, a sliding block 26, a return spring 27, a first rack 28 and a gear 30. The top block 23 is fixed at the middle position of the inner bottom of the protection plate 4. The second vertical slot 24 is vertically arranged at the middle position of the inner side of the dike 3 and extends to the inside of the storage groove 9. The top end of the inner side of the second vertical slot 24 is provided with the first sliding slot 25. The first sliding slot 25 is horizontally and slidingly provided with the sliding block 26.

[0045] Partial working principle: in the process of rising of the protection plate 4, the top block 23 moves upward in the second vertical slot 24. When the top block 23 contacts the sliding block 26, the sliding block 26 is pressed toward the inside of the first sliding slot 25. At the same time, the first rack 28 moves horizontally. The movement of the first rack 28 drives the gear 30 to rotate clockwise. Since the gear 30 is installed on the shaft 29, the shaft 29 is rotated in a transmission manner. The top rod 31 at the end of the shaft 29 is attached to the outer side of the protection plate 4.

[0046] In the embodiment, the sealing mechanism 8 comprises a second sliding slot 32, a sealing strip 33 and a second rack 34. The second sliding slot 32 is arranged at the top of the inner side of the dike 3 along the length direction of the dike 3. The second sliding slot 32 is slidingly provided with the sealing strip 33. The inner side of the sealing strip 33 is fixed with the second rack 34 which is engaged with the top of the gear 30. The second rack 34 is slidingly connected with the dike 3.

[0047] Partial working principle: in the process of rotation of the gear 30, the second rack 34 is controlled to move toward the direction of the protection plate 4. The second rack 34 pushes the sealing strip 33 out of the inside of the second sliding slot 32. The end of the sealing strip 33 is tightly attached to the protection plate 4 to increase the sealing effect between the protection plate 4 and the dike 3.

[0048] In the embodiment, the lower supporting mechanism 7 comprises a supporting block 35 and a telescopic assembly. The supporting block 35 is slidingly arranged at the inner side of the dike 3. The supporting block 35 is below the highest lifting position of the protection plate 4. The top of the supporting block 35 is at the same horizontal plane as the bottom end of the highest lifting position of the protection plate 4. The inside of the dike 3 is provided with the telescopic assembly which controls the horizontal sliding of the supporting block 35.

[0049] Part working principle: after the protection plate 4 rises to the highest position, if the liquid level of the flood continues to rise, the telescopic assembly is used to control the sliding of the supporting block 35 out of the inside of the dike 3 and adhere to the bottom of the protection plate 4, thereby supporting the bottom of the protection plate 4.

[0050] In the embodiment, the telescopic assembly comprises a transmission bin 36, a second floating plate 37, a hinged seat 38, a connecting rod 39 and a positioning block 40. The transmission bin 36 is arranged in the inside of the dike 3 and is communicated with the through slot 21. The second floating plate 37 is horizontally arranged in the inside of the transmission bin 36. The hinged seat 38 is arranged on the top of the second floating plate 37. The connecting rod 39 is symmetrically hingedly arranged at both ends of the hinged seat 38.

The positioning block 40 is perpendicularly arranged at the inner end of the supporting block 35 and is in abutment with the top of the connecting rod 39.

[0051] Part working principle: when the liquid level of the flood rises into the inside of the transmission bin 36, the upward movement of the second floating plate 37 is controlled. The upward movement of the second floating plate 37 will expand the two connecting rods 39 outward. The maximum expansion angle of the connecting rod 39 is 180°. The expansion of the connecting rod 39 will push the supporting block 35 out. If the liquid level of the flood is lower than the transmission bin 36, the flood will not cause a large impact force on the protection plate 4, so it is not necessary to use the supporting block 35 to reinforce and support the protection plate 4. When the water level drops, the second floating plate 37 automatically moves downward. The connecting rod 39 can pull the supporting block 35 back to the inside of the dike 3 for resetting, so that the protection plate 4 can be smoothly reset.

Any skilled person in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the disclosed range, which belongs to the protection scope of the present application.
