[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0032] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] The automatic guided flood-proof door applicable to the internal angle track groove in the present application is mainly used for sealing the flood-proof door of the automatic guided track groove containing the internal angle (acute angle), and is specifically used in the drop-down flood-proof door whose track groove is grooved and has the internal angle.

[0034] See also Figure 1 , and combined with Figure 2-Figure 4 The flood-proof door in the present application has a main structure including a door leaf 1 and a door frame 2. By arranging a circumferential sealing strip 3 on the door leaf 1, arranging the circumferential sealing strip 3 as an integral structure and arranging it around the door leaf 1, the overall sealing of the door leaf 1 can be achieved.

[0035] Specifically, the circumferential sealing strip 3 includes an integrally formed closed-loop sealing rubber ring, which is installed around the inner panel surface and the bottom side wall of the door leaf 1, so that the circumferential sealing strip 3 can be arranged as a whole on the door leaf 1 of the flood-proof door.

[0036] The closed-loop sealing rubber ring is arranged on the flood-proof door leaf 1 as a whole. Specifically, the closed-loop sealing rubber ring is arranged around the inner panel and the bottom of the door leaf 1 on the flood-proof door. The circumferential sealing strip 3 is formed in one step or hot-melt glued to avoid overlapping and interfaces of the rubber strip, which is more adaptable to the special-shaped track groove structure surface to achieve overall sealing.

[0037] In order to further ensure the sealing effect, the closed-loop sealing rubber ring includes two closed-loop sealing rubber rings, which are arranged at intervals. Specifically, each closed-loop sealing rubber ring includes a part arranged on the inner side plate surface and a part folded and attached to the bottom side wall of the door leaf 1. The above two parts of each closed-loop sealing rubber ring are combined into a closed-loop overall structure.

[0038] The two closed-loop sealing rubber rings are arranged on the inner panel surface and are arranged inside and outside the inner panel surface, while the part attached to the bottom side wall of the door leaf 1 after folding is arranged at intervals in the thickness direction of the door leaf 1. Through this arrangement, the two closed-loop sealing rubber rings can be fully squeezed and a good sealing effect can be guaranteed.

[0039] Through this sealing form, the circumferential sealing strip 3 can be squeezed downward as a whole, so that the part arranged on the inner plate surface is squeezed and sealed with the structural surface of the track groove, and the part attached to the bottom side wall of the door leaf 1 after folding is squeezed and sealed with the sealing surface of the embedded door frame 2.

[0040] From the perspective of automatic guided sliding, with the direction of insertion of the door leaf 1 into the door frame 2 as the standard, the inclined slide 21 is arranged on the inner wall on the right side of the door frame 2, and is respectively located on the top and bottom sides of the door frame 2, combined with the guide wheel 11 arranged on the side of the door leaf 1, so that during the descending process of the door leaf 1, with the cooperation of the inclined slide 21 and the guide wheel 11, the door leaf 1 and the side and bottom of the second-step concrete step are squeezed and sealed, so that the insertion action of the door leaf 1 into the door frame 2 embedded in the concrete structure is simple and reliable.

[0041] Furthermore, a guide rail groove 22 is provided on the inner side wall on the right side of the door frame 2 . The guide rail groove 22 includes two guide rail grooves 22 arranged at intervals. The two guide rail grooves 22 are arranged at intervals in the thickness direction of the right side frame of the door frame 2 .

[0042] The oblique slideway 21 extends in the direction of the guide rail groove 22 and is inclined in the opposite direction of the insertion of the door leaf 1. Through this structure, the oblique slideway 21 can more fully play its guiding role and effectively ensure the smoothness of the action process.

[0043] In the present application, a locking mechanism is arranged inside the door leaf 1, constituting a built-in locking structure of the door leaf 1. The locking mechanism includes a driving mechanism and a transmission mechanism 7. The driving mechanism is specifically a motor electromagnetic clutch combination, which is connected to the transmission mechanism 7 through a reducer 4. The motor rotates to drive the reducer 4 to rotate, thereby realizing the telescopic action of the locking head and the action of the rotating sealing mechanism 6 located at the bottom.

[0044] The transmission mechanism 7 comprises a commutator 71, a horizontal connecting rod assembly 72 and a vertical connecting rod assembly 73. The output terminal of the transmission mechanism 7 is connected to the locking head and the locking sleeve assembly.

[0045] The rotating sealing mechanism 6 is linked with the locking mechanism. The locking mechanism includes a bottom locking head 5 located at the bottom. The rotating sealing mechanism 6 is connected to the bottom locking head 5 through an inclined push rod 62. The rotating sealing mechanism 6 includes a side sealing block 61. The inclined push rod 62 is arranged between the side sealing block 61 and the bottom locking head 5.

[0046] Preferably, the bottom locking head 5 is connected with a telescopic universal joint 51, and a universal joint 63 is arranged on the inclined push rod 62, and the locking mechanism as a whole realizes effective sealing between the door leaf 1 and the track groove and the door frame 2, that is, the above-mentioned part of the circumferential sealing strip 3 arranged on the inner panel surface is squeezed and sealed with the structural surface of the track groove, and the part attached to the bottom side wall of the door leaf 1 after folding is squeezed and sealed with the sealing surface of the embedded door frame 2.

[0047] At the same time, during the movement of the locking mechanism, the bottom locking head 5 can push the side sealing block 61 obliquely through the inclined push rod 62 and the universal joint 63 to ensure the synchronous sealing of the locking mechanism and the concrete inner corner.

[0048] Furthermore, the side sealing block 61 is specifically the lower right corner sealing block of the door leaf 1. The lower right corner sealing block is opposite to the inner corner of the track groove. Through the action of the locking mechanism, the inclined push rod 62 and the universal joint 63 are driven to push the lower right corner sealing block outward obliquely, thereby ensuring effective sealing of the inner corner of the track groove.

[0049] By using the form of inclined push rod 62 and universal joint 63 to push the lower right corner sealing block obliquely, the lower right corner sealing block can be pushed only when the bottom locking head 5 is pushed, so that the lower right corner sealing block is located at the inner side of the door leaf 1 as the door leaf 1 falls, which greatly reduces the interference between the lower right corner sealing block and the door frame 2 during the sliding of the door leaf 1, thereby greatly reducing the friction resistance during the movement of the sealing device, while ensuring the synchronous sealing of the locking mechanism and the concrete inner corner.

[0050] It should be pointed out that, through the flood-proof door in the present application, the overall sealing of the flood-proof door with a special-shaped track groove including a concave corner can be achieved; at the same time, through the cooperation of the oblique slide 21 on the right side of the door frame 2 and the guide wheel 11 of the door leaf 1, the extrusion sealing of the left step of the special-shaped cross-section of the flood-proof door can be achieved; further combined with the linkage between the bottom locking head 5 and the lower right corner sealing block, the extrusion sealing of the right step of the special-shaped cross-section of the flood-proof door can be achieved, thereby achieving good sealing at different locations.

[0051] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0052] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
