DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings.

[0027] A suspended door includes two base columns distributed on the left and right, namely a first base column 4 and a second base column 5. A base frame 1 is provided between the two base columns. A gate plate 2 is provided on the base frame 1. A lifting component is connected between the gate plate 2 and the base frame 1. An opening and closing component is connected between the base frame 1 and the base columns. The lifting component controls the movement of the gate plate 2 in the vertical direction, and the opening and closing component realizes the movement of the base frame 1 in the parallel direction.

[0028] The base frame 1 includes a base beam 6 and a guide rail 7. The base beam 6 and the guide rail 7 are distributed in parallel along a horizontal contour. A plurality of lining beams 8 are connected between the base beam 6 and the guide rail 7. The plurality of lining beams 8 are distributed in a linear array along the axial direction of the guide rail 7. A supporting beam 9 is connected between the lining beam 8 located at the outermost edge and the end of the guide rail 7. The base beam 6, the guide rail 7, and the lining beam 8 form a ladder-shaped frame structure. The supporting beam 9 is used to enhance the strength of the frame structure.

[0029] The lifting assembly includes a guide beam 10 and a guide groove 11. The guide beam 10 is fixed on the lining beam 8. The guide groove 11 is fixed on the gate plate 2 through the lining plate 12. The guide beam 10 is matched with the guide groove 11. The guide groove 11 and the guide beam 10 provide guidance for the gate plate 2 to move in the vertical direction.

[0030] The lifting assembly includes an electric cylinder 13, the cylinder body of the electric cylinder 13 is fixed on the lining beam 8 through a cylinder seat 15, and a connecting member 14 is connected between the cylinder shaft of the electric cylinder 13 and the lining plate 12. The connecting member 14 is a "T"-shaped structure, and the horizontal side of the "T"-shaped structure is fixedly connected to the lining plate 12, and the vertical side of the "T"-shaped structure passes through the lining beam 8 and is connected to the cylinder shaft of the electric cylinder 13.

[0031] The opening and closing assembly includes a motor 16, which is fixed on the first base column 4. The motor 16 is connected to the gear box 17. A rack 19 is fixed on the guide rail 7. The rack 19 is engaged with the output gear in the gear box 17. The rack 19 is parallel to the track 7.

[0032] The opening and closing assembly includes a guide wheel 3, and the guide wheel 3 is located in the guide rail 7. When the opening and closing assembly is started, the guide wheel 3.

[0033] The gate plate 2 and the base column are both provided with side plates 18 , and the side plates 18 on the gate plate 2 fit in with the side plates 18 on the base column, and together with the gate plate 2 form a sealing gate with a “C”-shaped structure in horizontal cross section.

[0034] A limiting groove 20 is provided on the second base column 5, and the limiting groove 20 is a "C"-shaped structure. The two ends of the "C"-shaped structure of the limiting groove 20 are wide-mouth structures that are normally open outward. A guide wheel 21 is provided at the end of the base beam 6. There are two guide wheels 21. When the floating door is closed, the guide wheel 21 is embedded in the limiting groove 20.

[0035] Sealing strips are provided at the bottom of the gate plate 2, the bottom of the side plate 18, and between the two matching side plates.

[0036] During installation, the base columns on both sides are fixed to the side walls of the applicable scene, and sealing strips of appropriate thickness are installed according to the height of the gate plate 2 from the ground to ensure effective sealing during flood control. During normal use of the floating door, the gate plate 2 needs to be raised a certain distance using the lifting assembly to prevent the sealing strip at the bottom of the gate plate 2 from contacting the ground. When flood control is required, the gate plate 2 is lowered using the lifting assembly to achieve sealing.

[0037] The water-facing side of the floating door features a gate 2 that can be finely adjusted up and down. This gate 2 is raised and lowered by a lifting assembly. Side panels 18 with inverted triangular and triangular slopes are located on either side of the gate 2 and on the two base columns. Sealing strips are installed on the corresponding contact surfaces. Sealing strips are also designed where the bottom of the gate 2 contacts the ground, forming a looped connection. Symmetrical triangular structures are designed at the bottom corners of the gantry at both ends of the floating door to accommodate the gate's inverted triangles. When the gate 2 is lowered into place, the sloped surface of the gate 2 squeezes the sealing strip against the base column and the ground, effectively blocking the intrusion of external water. This design is particularly suitable for locations requiring high waterproofing, such as basement entrances and garage doors.

[0038] During normal use of the floating door, the base frame 1 is moved by the opening and closing assembly to achieve passage and blocking, and the gate plate 2 is normally closed. Only when the flood control and flood discharge functions are required, the gate plate 2 is driven up and down by the lifting assembly to achieve flood control and flood discharge functions. The lifting assembly, gate plate 2, side panels 18 and other structures are all installed on the base frame 1. When the base frame 1 normally performs the functions of passage and road closure, it does not increase the occupied space.

[0039] After the suspended door is put into use, it only needs regular maintenance. Since the opening and closing of the overall base frame 1 is frequently performed by the opening and closing components, only routine maintenance and lubrication are required at the gear meshing point. During the flood season, only the lifting component needs to be used to open and close the gate plate 2 to ensure that it can work normally. After the flood season, only the sealing strip connected to the gate plate needs to be cleaned.

[0040] Example 1: Lifting and lowering of a suspended door

[0041] When the gate plate 2 needs to be raised, the electric cylinder 13 is started. The electric cylinder 13 lifts the gate plate 2 upward through the transmission of the connecting member 14. When the gate plate 2 is lifted, the side plate 18 on the gate plate 2 is separated from the side plate 18 on the base column.

[0042] When the suspension door needs to be lowered, the cylinder shaft of the electric cylinder 13 is simply reset.

[0043] Example 2 Opening and closing of the suspended door

[0044] When the gate 2 needs to be opened, the motor 16 is started to drive the output gear of the gear box 17 to rotate, and the rack 19 is driven to move horizontally by meshing with the rack 19, so that the gate 2 is finally leveled to the east.

[0045] When the gate 2 needs to be closed, the motor 16 is started in the reverse direction. When the gate 2 is completely reset, the guide wheel 21 will be embedded in the limiting groove 20 to play a role of buffering and guiding.

[0046] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Any changes that may be made to certain parts thereof by those skilled in the art all reflect the principles of the present invention and fall within the scope of protection of the present invention.
