[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1 As shown;

[0030] A road engineering drainage filtering device comprises a drainage box 1 and a drainage pipe 2. The drainage pipe 2 is arranged outside the drainage box 1.

[0031] In this embodiment: After checking the public (announcement) number: CN214634389U discloses a municipal drainage filter device. Although the design can quickly install and clamp the filter box to ensure the stability of the filter box, and it is also faster when repairing and replacing. However, during the drainage filtration process, garbage in the water flow will gather at the bottom of the filter box, which will block the filter holes and cause drainage difficulties, reducing the efficiency and practicality of the municipal drainage filter device. In order to solve this technical problem, a filter component 3 is added on this basis.

[0032] More specifically:

[0033] like Figures 1 to 8 As shown:

[0034] In combination with the above content: the filter assembly 3 includes a filter barrel 31 and a clamping ring 34, the filter barrel 31 is rotatably connected to the inside of the drainage box 1, and the inner surface of the filter barrel 31 is evenly and equidistantly fixedly connected with multiple clamping rings 34, the clamping ring 34 is an annular structure, and a motor 36 is installed inside the drainage box 1, and the end of the output shaft of the motor 36 is fixedly connected to a connecting block 37, and a pressure sensor 39 is provided on the lower surface of the motor 36.

[0035] In this embodiment: by setting the filter barrel 31 into a barrel structure, the filter barrel 31 is rotated during the drainage process. Under the action of centrifugal force, a vortex is formed inside the filter barrel 31, and the water flow will be efficiently discharged from the filter barrel 31. The garbage in the water flow will adhere to the inner wall of the filter barrel 31 under the action of centrifugal force. When the garbage accumulates in the filter barrel 31 and causes blockage, it will cause an increase in the water accumulation in the filter barrel 31, thereby triggering the pressure sensor 39 under the filter barrel 31 to alarm. The staff can solve the problem of blockage of the filter barrel 31 in time, and a plurality of side through holes 32 are opened on the outside of the filter barrel 31 to ensure smooth drainage and improve drainage efficiency.

[0036] It should be noted that: through the rotation of the filter barrel 31, the water flow follows the rotation driven by the inner wall of the filter barrel 31, and forms a vortex with the axis of rotation of the filter barrel 31 as the center, thereby increasing the centrifugal force of the garbage in the water flow.

[0037] Going further:

[0038] In an optional embodiment, a limiting ring 33 is fixedly connected to the inner surface of the drainage box 1 , and the inner surface of the limiting ring 33 is slidably connected to the outer side of one end of the filter barrel 31 .

[0039] In this embodiment, by providing a limiting ring 33, the position of the filter barrel 31 can be limited, so that the filter barrel 31 is more stable during the rotation process.

[0040] Going further:

[0041] In an optional embodiment, a plurality of second filter holes 35 are evenly and annularly formed on the outer side of the bottom end of the filter barrel 31 .

[0042] In this embodiment: when the water flow rotates inside the filter barrel 31, an impact force is applied to the bottom of the filter barrel 31, thereby opening a second filter hole 35, which can exclude the water flow from the filter barrel 31 to the greatest extent, and to a certain extent prevent the drainage blockage caused by the accumulation of garbage on the inner wall of the filter barrel 31, thereby improving the practicability of the road engineering drainage filtration device.

[0043] Going further:

[0044] In an optional embodiment, a special-shaped groove 38 matching the motor 36 is formed on the lower surface of the filter barrel 31 , and the filter barrel 31 is plugged into the motor 36 via the special-shaped groove 38 .

[0045] In this embodiment, the plugging and connection between the filter barrel 31 and the connecting block 37 ensures the convenience of disassembly and cleaning.

[0046] It should be noted that the motor 36 can move up and down inside the groove of the drainage box 1 to cooperate with the operation of the pressure sensor 39. The pressure sensor 39 is equipped with an alarm device. When the water accumulated inside the filter barrel 31 reaches a certain weight, the pressure sensor 39 is triggered to sound an alarm.

[0047] Working principle: by setting the filter barrel 31 into a barrel structure, starting the motor 36, and making the filter barrel 31 rotate during the drainage process, a vortex is formed inside the filter barrel 31 under the action of centrifugal force, and the garbage in the water flow will adhere to the inner wall of the filter barrel 31 under the action of centrifugal force, and the water flow will be efficiently discharged from the filter barrel 31. When too much garbage accumulates on the inner wall of the filter barrel 31 and causes the filter barrel 31 to be blocked, the increase in water inside the filter barrel 31 causes its gravity to increase, thereby triggering the pressure sensor 39 under the filter barrel 31 to notify the staff to clean it in time, and a plurality of side through holes 32 are opened on the outside of the filter barrel 31 to ensure smooth drainage and improve drainage efficiency. By setting a limit ring 33, the position of the filter barrel 31 can be limited, and by setting a limit ring 33, the filter barrel 31 can be The position is limited, so that the filter barrel 31 is more stable during the rotation process, and the service life of the pressure sensor 39 is increased. When the filter barrel 31 needs to be cleaned, it is only necessary to take out the filter barrel 31 from the limiting ring 33. The clamping ring 34 protrudes toward the inside of the filter barrel 31 and is arranged in a ring shape on the inner surface of the filter barrel 31. When the garbage in the water flow slides downward on the inner surface of the filter barrel 31, the clamping ring 34 will block it, and further prevent the garbage from accumulating at the bottom of the filter barrel 31. When the water flow rotates inside the filter barrel 31, an impact force is applied to the bottom of the filter barrel 31, thereby opening the second filter hole 35, which can exclude the water flow from the filter barrel 31 to the greatest extent, and to a certain extent prevent the drainage blockage caused by the accumulation of garbage on the inner wall of the filter barrel 31, thereby improving the practicability of the road engineering drainage filter device.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
