Cylinder filter shown in the drawings, including coaxial urceolus 5 and collecting pipe 6. Described urceolus 5 is cylindrical stainless steel mesh cylinder, the upper and lower two ends of stainless steel mesh cylinder are with rustless steel bound edge, and bound edge can improve the stability of stainless steel mesh cylinder, and bound edge circumference is drilled with through hole, adopt stainless steel material, it is possible to make urceolus 5 have intensity feature high, corrosion resistant. Collecting pipe 6 be two ends with externally threaded pipe, tube wall has water hole or cross tank, rainwater can pass through water hole or cross tank enter collecting pipe 6 inside. The inner surface of urceolus 5 and the outer surface of collecting pipe 6 are respectively with one layer of lining net, and the aperture of lining net is less than the particle diameter of filter medium, it is possible to prevent filter medium from spilling, and filter medium is contained in the annular space that the two lining net is defined. Rainwater, from the surrounding of urceolus 5 through urceolus 5 and outer lining net, horizontally enters into filter medium, after the filtration of filter medium, enters collecting pipe 6 through the water hole on liner net and collecting pipe 6 or mistake tank, is then drained by drain pipe.

Base 7 is respectively fixedly connected with urceolus 5 and collecting pipe 6. the annular groove of base 7 can be put in the lower end of urceolus 5, urceolus 5 and base 7 is coupled together by pin 11, and the female thread with externally threaded plug 10 with base 7 pin-and-hole front end is threadeded, it is possible to the anti-outside play of shotpin 11. base 7 center is a screwed hole, the female thread elder generation gluing of the external screw thread of collecting pipe 6 lower end and base 7 screwed hole of centre, then carries out threaded, it is possible to plays and seals and locking effect. base 7 screwed hole of centre the groove that Open Side Down is presented herein below, current limiting plate 13 is put in groove and is connected with base 7 by bonding agent, can control the flow of rainwater entrance drain pipe by changing the size of current limiting plate 13 centre bore. an annular groove is had near screwed hole of centre place bottom base 7, bottom sealing ring 12 is installed bottom annular groove, cylinder filter is connected with being embedded in underground drainage connecting pipe by this annular groove, drainage connecting pipe has one section and elevates above the soil, Open Side Down and A/F is more than bottom width for annular groove, drainage connecting pipe can be made to conveniently insert in annular groove, when cylinder filter is connected with the drainage connecting pipe elevated above the soil, the bottom surface of base 7 can fall on the ground, bottom sealing ring 12 and drainage connecting pipe can produce crush seal simultaneously, it is possible to prevent the gap that rainwater passes through between bottom surface and the ground of base 7 to enter drain pipe.

Bracing frame 4 can be enclosed within the upper end of urceolus 5, and bracing frame 4 is fixed with the upper end of urceolus 5 be connected by the first screw 8 and the first nut 9. Two handles 1 are had, it is possible to facilitating a dead lift or equipment lifting, handle 1 is fixed with cover plate 3 be connected by the second screw 15 and the second nut 16 above cover plate 3. The top of urceolus 5 is detachably connected with bracing frame 4; The top of collecting pipe 6 is detachably connected with gland 2; Cover plate 3 coordinates spacing by bracing frame 4 and realizes fixing under the effect of described gland 2; Bracing frame 4 is fixed on described urceolus 5 by bolt; The inwall of bracing frame 4 is provided with to support the support lugn 4a of cover plate 3; The support lugn 4a upper end of bracing frame 4 is additionally provided with in order to the positive stop lug boss 4b that cover plate 3 is spacing; Positive stop lug boss 4b is in a rotationally symmetrical arrangement relative to the central axis of urceolus 5; In a rotationally symmetrical arrangement on the sidewall of cover plate 3 have the connection boss 3a that can coordinate with the positive stop lug boss 4b on bracing frame 4;That is bracing frame 4 has the groove of similar spline, and cover plate 3 circumference has the boss of similar spline, the boss on cover plate 3 can be put in the groove on bracing frame 4, after being rotated to an angle by cover plate 3 by handle 1, can be formed between the two and be connected. This structure can make cover plate install easily and dismantle. The centre bore of cover plate 3 is formed with collecting pipe 6 upper end and coordinates, and is sealed by O-ring seals 14, it is possible to prevent rainwater to be directly entered collecting pipe 6 not past the process of filter medium. The female thread of gland 2 is threadeded with the external screw thread of collecting pipe 6 upper end, and gland 2 is pressed in cover plate 3 surface, and gland 2 can ensure that when being carried by handle 1 or lifted by crane cylinder filter, cover plate 3 uniform force. When rainfall is very big, water level exceeds cylinder filter top, and gland 2 is also prevented from rainwater and is directly entered collecting pipe 6 without the process of filter medium.

Whole cylinder filter Stability Analysis of Structures is reliable, it is possible to installs at the scene and dismounting easily, can also change filter medium simultaneously easily, reduce workload, improves efficiency.

Should be understood that; the above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by this utility model; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model.
