[0088] In this embodiment, when in use, the lock catch 23 can be unlocked, and the hinge 22 can drive the cover plate 20 to unfold. The insertion plate 7 on the filter plate 6 is inserted into the inner side of the slot, so that the filter plate 6 is lapped on the sedimentation plate 5 for preliminary docking. Then, the pull ring 81 is buckled and the movable rod 8 is pushed to stretch the two groups of second springs 17 by the pressing plate 16. At this time, the clamping block 10 and the positioning block 9 are both in the longitudinal direction and can be slidably docked with the first docking groove 11. After the clamping block 10 and the positioning block 9 enter the inner side of the circular groove 12, the pull ring 81 is twisted to drive the clamping block 10 to rotate to the transverse direction inside the circular groove 12, and the movable rod 8 is continuously pushed inward to be clamped with the spinning component and the clamping component.

[0089] In an alternative embodiment of the present invention, the spinning component includes:

[0090] The first springs 13 are arranged at both ends of the inner wall of the installation groove 51. The other ends of the first springs 13 are provided with installation disks 14. The inside of the installation disk 14 is rotatably connected with a movable seat 15. A positioning groove for clamping with the positioning block 9 is formed on one side of the movable seat 15.

[0091] When in use, the positioning block 9 is clamped with the movable seat 15 through the positioning groove.

[0095] When in use, the abutting block 18 is clamped with the clamping block 10.

[0096] In an alternative embodiment of the present invention, inclined surfaces 19 that fit each other are formed at the opposite ends of the abutting block 18 and the clamping block 10. A groove for engaging with the protruding end of the clamping block 10 is formed on one side of the abutting block 18.

[0097] When in use, the abutting block 18 is clamped with the protruding end of the clamping block 10 through the groove.

[0098] In this embodiment, when the movable rod 8 is continuously pushed inward after being rotated to the horizontal direction, the two groups of second springs 17 are continuously stretched by the extrusion plate 16, the block 10 contacts the surface of the abutment block 18, and the two groups of inclined surfaces 19 abut against each other, forcing the abutment block 18 to compress the third spring 181 to retract. When one end of the positioning block 9 is inserted into the inner side of the positioning groove, one end of the abutment block 18 is no longer blocked, so that it can rebound and reset, and the protruding end of the block 10 is then inserted into the inner side of the groove for positioning, and the plug plate 7 is also positioned accordingly, completing the locking of the filter plate 6; when it is necessary to disassemble and clean, it is only necessary to press the movable rod 8 again, and the positioning block 9 squeezes the movable seat 15 and the mounting plate 14 to allow the two groups of first springs 1 3 is retracted, forcing the protruding end of the block 10 to be separated from the inner side of the groove, wherein the cross section of the mounting groove 51 is circular, and the two groups of blocks 10 can be rotated around the movable rod 8 inside thereof, and the movable rod 8 is twisted by buckling the pull ring, and the movable seat 15 can be rotated accordingly by cooperating with the positioning block 9 and the positioning groove. After the block 10 is rotated to the longitudinal position, the pull ring 81 is loosened back, and the extrusion plate 16 is pulled back by the second spring 17. The block 10 and the positioning block 9 slide into the inner side of the first docking groove 11, and then slide into the inner side of the retraction groove 54 for storage. At this time, the position of the plug plate 7 is no longer locked, and the filter plate 6 can be pulled up by holding one end to complete the disassembly, waiting for the staff to perform more detailed cleaning.

[0099] The specific working principle of the drainage device for civil construction described in the present invention is as follows: unlocking the lock buckle 23 and cooperating with the hinge 22 can drive the cover plate 20 to unfold, inserting the plug plate 7 on the filter plate 6 into the inner side of the slot, allowing the filter plate 6 to overlap the sedimentation plate 5 for preliminary docking, buckling the pull ring 81 to drive the movable rod 8 to move, allowing the extrusion plate 16 to stretch the two sets of second springs 17. At this time, the clamping block 10 and the positioning block 9 are both longitudinal and can slide with the first docking groove 11. After the clamping block 10 and the positioning block 9 enter the inner side of the circular groove 12, the twisting pull ring drives the clamping block 10 to rotate to the horizontal direction inside the circular groove 12. After rotating to the horizontal direction, the movable rod 8 continues to be pushed inward, and the two sets of second springs 17 continue to be stretched by the extrusion plate 16. The clamping block 10 contacts the surface of the abutment block 18, and the two sets of inclined surfaces 19 abut against each other, forcing the abutment block 18 to compress the third spring to retract. When one end of the positioning block 9 is stuck in the inner side of the positioning groove, one end of the abutment block 18 is no longer blocked, allowing it to rebound. After the filter plate 6 is reset, the protruding end of the card block 10 is then stuck into the inner side of the groove for positioning, and the plug plate 7 is also positioned accordingly, completing the locking of the filter plate 6. When it needs to be disassembled and cleaned, it is only necessary to press the movable rod 8 again, and the positioning block 9 squeezes the movable seat 15 and the mounting plate 14 to allow the two groups of first springs 13 to retract, forcing the protruding end of the card block 10 to disengage from the inner side of the groove. The cross-section of the mounting groove 51 is circular, which can be used for the two groups of card blocks 10 to rotate around the movable rod 8 on its inner side, buckle the pull ring 81 to drive the movable rod 8 to twist, and cooperate with the positioning block 9 and the positioning groove to make the movable seat 15 rotate accordingly. After the card block 10 position is rotated to the longitudinal direction, the pull ring 81 is loosened back, and the extrusion plate 16 is pulled back by the second spring 17 to reset, and the card block 10 and the positioning block 9 slide into the inner side of the first docking groove 11, and then slide into the inner side of the retraction groove 84 for storage. At this time, the position of the plug plate 7 is no longer locked, and the filter plate 6 can be pulled up by holding one end to complete the disassembly, waiting for the staff to perform more detailed cleaning.

[0100] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
