[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-6 This is an embodiment of the present invention, specifically, it discloses a drainage manhole cover device, the manhole cover device includes a drainage box 1 installed in a drainage manhole, and a manhole cover 2 is placed above the drainage box 1;

[0026] The inner side of the drainage box 1 has a placement position 11, and the filter box 3 is placed in the placement position 11. The bottom of the drainage box 1 and the end surface of the filter box 3 are both provided with drainage holes 4;

[0027] A locking assembly 5 is provided between the filter box 3 and the drainage box 1 , and an unlocking assembly 6 adapted to the locking assembly 5 is provided on the filter box 3 , and the unlocking assembly 6 is used to unlock the locking assembly 5 so as to remove the filter box 3 from the inner side of the placement position 11 .

[0028] In some embodiments, the drainage box 1 in the present invention includes four evenly rectangularly distributed side surfaces 12, and the bottom of the side surfaces 12 is fixedly connected with an inclined surface 13. The four inclined surfaces 13 are connected in sequence and form the placement position 11 at the bottom connection. Specifically, the placement position 11 described in this embodiment is a rectangular structure and extends toward the bottom direction of the drainage box 1. A bending surface 14 bent outward is also provided between the tops of the four side surfaces 12. The bending surface 14 is used to place the manhole cover 2. Preferably, in this embodiment, each of the side surfaces 12 and the inclined surfaces 13 are welded and fixed to each other to form a whole.

[0029] Furthermore, the drainage holes 4 described in this embodiment are formed on the inclined surface 13 and the placement position 11. Specifically, the drainage holes 4 described in this embodiment are formed on the four inclined surfaces 13 and the sides and bottom of the placement position 11. Drainage holes 4 are also formed on the four sides and bottom of the filter box 3. Through the design of the drainage holes 4 on the inclined surface 13, the rainwater can be initially filtered when it passes through. The rainwater is discharged along the drainage holes 4 on the inclined surface 13, and the impurities slide downward along the inclined surface 13 until they slide into the filter box 3. At the same time, since the placement position 11 and the bottom of the filter box 3 are also provided with drainage holes 4, the impurities collected in the filter box 3 can be filtered again to ensure that the rainwater is continuously discharged while the impurities are collected.

[0030] In some embodiments, the locking assembly 5 in the present invention includes a suspension rod 51 fixed to the top of the filter box 3, and a plug rod 53 is movably inserted at the bottom of the suspension rod 51 through a spring 52. The end of the plug rod 53 can also be designed with a downward inclined surface to facilitate insertion with the fixed plate 15. The plug rod 53 is fixedly connected between the suspension rod 51 and the plug rod 53, and a fixed plate 15 is fixedly installed on the inner side of the drainage box 1. The plug rod 53 is inserted into the fixed plate 15. As a preferred embodiment, the plug rod 53 and the fixed plate 15 described in this embodiment are symmetrically arranged in two to improve the stability of the lock to avoid the filter box 3 from floating or shifting during the collection of impurities.

[0031] On the basis of the above embodiment, the present embodiment also includes a rotating sleeve 54 rotatably connected to the suspension rod 51, and two stop wings 55 are fixedly installed on the rotating sleeve 54. The two stop wings 55 are respectively located on both sides of the suspension rod 51, and the stop wings 55 and the rotating sleeve 54 can be fixed by bolts, wherein a rotating plate 7 is also fixedly installed at the bottom of the rotating sleeve 54, and both ends of the rotating plate 7 are connected to the plug rod 53 through a connecting rod 56, and the two ends of the connecting rod 56 are pinned to the plug rod 53 and the rotating plate 7 respectively, that is, when the rotating plate 7 rotates, it will drive the plug rods 53 on both sides to move synchronously, and when the plug rod 53 moves backward, it is separated from the fixed plate 15. At this time, the filter box 3 can be taken out from the inside of the placement position 11 to facilitate cleaning of impurities inside it.

[0032] Furthermore, the unlocking assembly 6 in this embodiment includes a hook rod 61, a groove is provided at the bottom of the hook rod 61, a lock head 63 is movably connected to the groove through a compression spring 62, and the lock head 63 is a wedge-shaped structure, and the inclined surface of the wedge-shaped structure is arranged toward the lower side of the filter box 3.

[0033] In addition, in this embodiment, the inner side of the rotating sleeve 54 has a slide 57 and a notch 58 that pass through the upper and lower sides, and a positioning hole 59 is opened on the outer side of the rotating sleeve 54. The positioning hole 59 is connected to the slide 57. The locking head 63 moves along the slide 57 and is snapped into the positioning hole 59. When the locking head 63 is in a free state, its end does not protrude from the surface of the rotating sleeve 54, so that it can slide out from the notch 58 easily.

[0034] That is, during operation, the filter box 3 is used to collect impurities in rainwater. When the filter box 3 needs to be cleaned, the manhole cover 2 is opened, and one end of the hook rod 61 is inserted into the inner side of the rotating sleeve 54 along the slide 57. At this time, the lock head 63 moves on the inner side of the slide 57 until the lock head 63 is engaged with the positioning hole 59 to complete the connection between the hook rod 61 and the rotating sleeve 54. The hook rod 61 is rotated, and the hook rod 61 drives the rotating sleeve 54 to rotate, thereby controlling the movement and separation of the insertion rod 53 and the fixing plate 15. At this time, the hook rod 61 can be pulled upward to remove the filter box 3 from the inside of the placement position 11 to pour out the impurities for cleaning.

[0035] When the filter box 3 is installed after cleaning, the filter box 3 is pulled downward by the hook rod 61 and placed in the placement position 11. When the filter box 3 is partially placed in the placement position 11, the hook rod 61 is also rotated to drive the insertion rod 53 to retract. The filter box 3 moves downward under the action of gravity until it is completely sunk into the placement position 11. Thereafter, the hook rod 61 can be reset to make the insertion rod 53 plug into the fixing plate 15 to complete the fixation. After fixation, the hook rod 61 is pushed downward. Since the lock head 63 is a wedge-shaped structure, the lock head 63 will continue to move downward until it moves along the slide 57 to the lower side of the rotating sleeve 54. At this time, the hook rod 61 is rotated to align the lock head 63 with the notch 58, and the hook rod lock head 63 is pulled upward to slide out along the notch 58 to facilitate the disassembly of the entire hook rod 61, and the manhole cover 2 is covered to complete the assembly.

[0036] In summary, in the present invention, when it rains, impurities on the ground will enter the drainage box 1 through the holes on the drainage manhole cover 2, and rainwater will flow smoothly into the drainage well through the drainage holes 4 of the drainage box 1. After being filtered, the debris will be retained in the interior of the filter box 3. The filter box 3 adopts a detachable structure design. After it is full of collection, it can be unlocked by the unlocking component 6 to lift the filter box 3 out of the well. After dumping the debris in the box, the filter box 3 is put back in place for recyclable collection. This design not only effectively prevents debris from clogging the drainage well, but also greatly facilitates the staff's work of cleaning up the debris.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
