[0030] Example

[0031] See also Figures 1 to 8 :

[0032] A low-opening adjustable weir door with good sealing performance includes a door frame 2, a door panel 1, a drive assembly, and a door panel adjusting member 18. The upper half of the door frame 2 is provided with a square mounting portion 17 with the same width as the door frame 2. The square mounting portion 17 is provided with a sealing strip 12 on the side facing the door frame 2. A door groove is provided on the inner side of the door frame 2. The left and right door grooves are provided with sealing strips 12 and door panel guide rails 13 parallel to the door groove and at the same height as the door groove on the door groove walls close to one end of the square mounting portion 17. The door panel guide rails 13 are provided next to the sealing strips 12. The door panel 1 is installed in the door groove and is close to the door panel guide rails 13 and the sealing strips 12. The door panel adjusting member 18 is provided on the outer side of the door groove side walls at one end of the door groove on the left and right sides of the door frame 2 away from the square mounting portion 17 and in contact with the door panel 1.

[0033] The driving assembly drives the door panel 1 to move up and down in the door groove. The door panel 1 is adjacent to the sealing strip 12 and the door panel guide rail 13. The door panel guide rail 13 makes the up and down movement of the door panel 1 parallel to the sealing strip 12. The door panel adjustment member 18 can press the door panel 1 against the sealing strip 12, so that the door panel 1 can fit tightly with the sealing strip 12 to form a seal.

[0034] Furthermore, a lifting lug 9 is provided at the middle position of the top of the door panel 1 , a bottom sealing block 10 is provided at the middle position of the bottom, small wedge blocks 7 are provided at the upper part of both sides of the door panel 1 , and large wedge blocks 8 are provided at the lower part.

[0035] The door panel 1 is provided with a lifting lug 9 at the top and a bottom sealing block 10 at the bottom, which can conveniently connect the drive assembly and enhance the sealing of the bottom of the door panel 1.

[0036] Furthermore, the bottom sealing block 10 is in the shape of a "U" with the opening facing upward. The bottom sealing block 10 is divided into a connecting end and an insertion end. The connecting end is connected to the door panel 1, and the insertion end is an inclined surface on the side close to the door panel 1 and a vertical surface on the side away from the door panel 1, forming a structure that is small at the top and large at the bottom.

[0037] Further, the driving assembly comprises a pin shaft 3, a mounting bracket 4, a manual opening and closing machine 5, and a screw rod 6. The screw rod 6 is fixed by the pin shaft 3 and a split pin through the hanger 9 arranged at the middle position of the top of the door frame 2 and the middle position of the top of the door plate 1. The mounting bracket 4 is further sleeved on the screw rod 6. The electric actuator is arranged on the mounting bracket 4. The mounting bracket 4 is arranged on the surface of the wall during the installation of the whole door frame 2. The screw rod 6 penetrates the wall.

[0038] The manual opening and closing machine 5 is started to drive the screw rod 6 to rotate, so that the screw rod 6 moves up and down, thereby moving the door plate 1 up and down. The mounting bracket 4 serves as the support frame of the manual opening and closing machine 5.

[0039] Further, the door groove is provided with a top sealing block 14 at the inner side of the end away from the square mounting part 17. The door groove is provided with a large wedge 8 at the upper part of the inner side of the outer wall of the door groove at the end away from the square mounting part 17. A small wedge 7 is arranged at the position close to the lower end of the square mounting part 17.

[0040] Further, when the door plate 1 is completely closed, the large wedge 8 on the door groove is above the small wedge 7 on the door plate 1, and the small wedge 7 on the door groove is above the large wedge 8 on the door plate 1.

[0041] When the door plate 1 rises to the highest position and contacts the top sealing block 14 at the top of the door groove, the large wedge 8 at the upper part of the door groove is in close contact with the small wedge 7 arranged at the upper part of the door plate 1, and the small wedge 7 at the lower part of the door groove is in close contact with the large wedge 8 arranged at the lower part of the door plate 1. Thus, the top and the left and right sides of the door plate 1 are sealed. The large wedge 8 and the small wedge 7 on the door groove are above the corresponding small wedge 7 and large wedge 8 on the door plate 1. The purpose is to enable the door plate 1 to move downward under the action of the driving assembly without being blocked by the large wedge 8 and the small wedge 7 on the door groove. During the downward movement, the two small wedges 7 do not contact.

[0042] Further, the door plate adjusting part 18 comprises a bolt 11, a stud 16, and a "7" shaped pressing plate 15. The stud 16 is vertically arranged on the side wall of the door groove at the end away from the square mounting part 17. The "7" shaped pressing plate 15 has the same height as the square mounting part 17. One end of the "7" shaped pressing plate 15 is sleeved on the stud 16, and the other end is vertically pressed against the door plate 1.

[0043] By tightening the bolt 11 on the stud 16, the "7" shaped pressing plate 15 is pressed downward to continuously press the door plate 1, so that the door plate 1 continuously moves to the direction of the sealing rubber strip 12, and the door plate 1 is in close contact with the sealing rubber strip 12, thereby completing the further sealing of the left and right sides of the door groove.

[0044] Furthermore, a hole is opened at the bottom of the lower end of the square mounting portion 17 at a position corresponding to the insertion end of the bottom sealing block 10 of the door panel 1, and the boundary of the hole facing the bottom sealing block 10 just corresponds to the upper end of the inclined side of the insertion end of the bottom sealing block 10 of the door panel 1.

[0045] When the door panel 1 moves upward, the insertion end of the bottom sealing block 10 of the door panel 1 will slowly enter the hole opened at the lower end of the mounting portion. Since the insertion end of the bottom sealing block 10 is an inclined surface on the side close to the door panel 1 and a vertical surface on the side away from the door panel 1, a structure with a small top and a large bottom is formed, and the hole opened at the lower end of the square mounting portion 17 is just corresponding to the upper end of the inclined surface of the insertion end of the bottom sealing block 10 set at the middle position of the bottom of the door panel 1 at the boundary close to the bottom sealing block 10. Then, when the door panel 1 continues to move upward, the door panel 1 will continue to slowly approach the direction of the sealing strip 12 as it moves upward, so that the bottom of the door panel 1 is tightly attached to the sealing strip 12 on the square mounting portion 17, thereby sealing the door panel 1 and the lower end of the square mounting portion 17.

[0046] The principle of this utility model is:

[0047] Vertical sealing strips 12 are installed on the left and right sides of the door slot, near the square mounting portion 17, to ensure a good seal between the door panel 1 and the door frame 2 when closed. At the same time, door panel guide rails 13, which are at the same height and parallel to the door frame 2, ensure the stability and accuracy of the door panel 1 during its up and down movement.

[0048] The drive assembly connects to the lug 9 at the top of the door panel 1 through the opening at the top of the door frame 2. When the manual door opener 5 or electric actuator is activated, the screw 6 moves the door panel 1 up and down within the door slot. During this movement, the door panel 1 remains in close contact with the door guide rail 13 and the sealing strip 12, ensuring a continuous seal.

[0049] To further enhance the sealing effect, a "U"-shaped bottom sealing block 10 is provided at the bottom of the door panel 1. The insertion end of the bottom sealing block 10 is inclined on the side close to the door panel 1 and vertical on the side away from the door panel 1. The top of the inclined surface is aligned with the boundary of the hole at the bottom of the square mounting portion 17 close to the door panel 1. As the door panel 1 rises, the lower end of the door panel 1 will automatically deviate toward the sealing strip 12, thereby achieving a tight seal under the door panel 1. In addition, a large wedge 8 and a small wedge 7 are provided on both sides of the door panel 1. When the door panel 1 rises to its highest point, the wedges on both sides of the door panel 1 will cling to the corresponding wedges in the door groove, and the top of the door panel 1 will cling to the top sealing block 14, which is the same length as the upper end of the door frame and is provided in the door groove opened at the upper end of the door frame 2, thereby achieving a seal on the left and right sides and the top of the door panel 1 and the door frame 2.

[0050] The door panel adjustment member 18 fine-tunes the position of the door panel 1 through the combination of the bolt 11, the stud 16, and the "7"-shaped pressure plate 15. By tightening the bolt 11, the "7"-shaped pressure plate 15 moves downward, squeezing the door panel 1, thereby making it fit more tightly with the sealing strip 12.

[0051] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Based on the technical essence of the present invention and within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present invention.
