Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a load-bearing steel fiber manhole cover. Background Art

[0002] Steel fiber manhole covers are widely used as road construction components in municipal construction. Since round manhole covers have outstanding balanced load-bearing capacity and are not easy to tilt, the manhole covers in municipal projects are mostly round in shape.

[0003] The prior art discloses a municipal road load-bearing steel fiber manhole cover with application number CN202221417516.2, which includes a manhole sleeve, a supporting flange fixed to the inner wall of the manhole sleeve, and a manhole cover plate arranged in the well sleeve. Two symmetrical drainage holes and two symmetrical drainage ports are provided on the surface of the manhole cover plate. A strip rod is provided inside the well sleeve, a connecting frame is fixedly connected to the strip rod, and two symmetrically arranged arc-shaped water retaining strips are fixedly connected to the connecting frame.

[0004] The above-mentioned shortcomings of the prior art are that manual operation is required to increase the drainage area, but there are many manhole covers, and manual adjustment is a relatively large workload; secondly, it is impossible to avoid the accumulation of debris on the manhole cover, causing the water inlet to be blocked, for example, being blocked by stones and then causing subsequent accumulation of debris; for this reason, the present application proposes a load-bearing steel fiber manhole cover. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a load-bearing steel fiber manhole cover.

[0006] The embodiment of the utility model provides a load-bearing steel fiber manhole cover, comprising:

[0007] A manhole cover, wherein four arc-shaped drainage openings are provided through the manhole cover;

[0008] Capable of accommodating four filter and drainage components; the filter and drainage component includes a through groove set through the manhole cover, the upper end of the manhole cover is provided with a sliding groove coaxially arranged with the through groove, a slip ring is slidably connected in the sliding groove, a return spring is fixedly connected between the slip ring and the sliding groove, a hemispherical filter is fixedly connected to the upper end of the slip ring, and a cross reinforcement plate is fixedly connected to the bottom of the manhole cover.

[0009] Furthermore, the upper end of the return spring is fixedly connected to the bottom of the slip ring, and the lower end of the return spring is fixedly connected to the inner bottom of the sliding groove.

[0010] Furthermore, the inner diameter of the sliding groove is larger than the inner diameter of the through groove, and the depth of the sliding groove is smaller than the depth of the through groove, a supporting edge is formed between the sliding groove, the through groove and the manhole cover, and the reset spring is fixed on the supporting edge.

[0011] Furthermore, when the return spring is in a free state, the upper end of the slip ring is flush with the upper end of the manhole cover.

[0012] Furthermore, the slip ring and the hemispherical filter can be completely accommodated in the sliding groove.

[0013] Furthermore, the cross reinforcement plate is formed by welding four right-angle trapezoidal plates, and the through grooves are staggered with the cross reinforcement plate and are arranged close to the cross reinforcement plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Due to the shape of the hemispherical filter screen, the utility model can wash away the debris and stones on the surface of the hemispherical filter screen under the action of the water flow, and is not easy to cause blockage. The setting of the through groove can increase the drainage area, thereby increasing the drainage volume, without manual adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a load-bearing steel fiber manhole cover, comprising:

[0022] A manhole cover 1, wherein four arc-shaped drain ports 2 are provided through the manhole cover 1, and the arc-shaped drain ports 2 are distributed in a circular array on the manhole cover 1;

[0023] The filter and drainage components can be accommodated; the filter and drainage components include a through groove 5 that penetrates the manhole cover 1, and a sliding groove 3 that is coaxially arranged with the through groove 5 is provided at the upper end of the manhole cover 1, and both the through groove 5 and the sliding groove 3 are circular in shape; the inner diameter of the sliding groove 3 is larger than the inner diameter of the through groove 5, and the depth of the sliding groove 3 is smaller than the depth of the through groove 5;

[0024] A slip ring 6 is slidably connected in the sliding groove 3, a return spring 7 is fixedly connected between the slip ring 6 and the sliding groove 3, the upper end of the return spring 7 is fixedly connected to the bottom of the slip ring 6, the lower end of the return spring 7 is fixedly connected to the inner bottom of the sliding groove 3, a support edge is formed between the sliding groove 3, the through groove 5 and the manhole cover 1, and the return spring 7 is fixed on the support edge;

[0025] The upper end of the slip ring 6 is fixedly connected with a hemispherical filter screen 8, and the slip ring 6 and the hemispherical filter screen 8 can be completely received in the sliding groove 3; wherein, when the return spring 7 is in a free state, the upper end of the slip ring 6 is flush with the upper end of the manhole cover 1, and when the tire of a car or a bicycle passes over the hemispherical filter screen 8, the hemispherical filter screen 8 is pressed to drive the slip ring 6 to move downward, and the return spring 7 is compressed at this time, so that the slip ring 6 and the hemispherical filter screen 8 can be received in the sliding groove 3, and when the hemispherical filter screen 8 is no longer pressed, the return spring 7 can reset the slip ring 6 and the hemispherical filter screen 8, and thus will not affect traffic;

[0026] On rainy days, the hemispherical filter 8 can filter stones and the like. Due to the shape of the hemispherical filter 8, the debris and stones on the surface of the hemispherical filter 8 can be washed away by the water flow, and it is not easy to cause blockage. The setting of the through groove 5 can increase the drainage area, thereby increasing the drainage volume, without manual adjustment.

[0027] A cross reinforcing plate 4 is fixedly connected to the bottom of the manhole cover 1. The cross reinforcing plate 4 is composed of four right-angled trapezoidal plates welded together. The through grooves 5 are staggered with the cross reinforcing plates 4 and are arranged close to the cross reinforcing plates 4. This can increase the portion of the manhole cover 1 where the through grooves 5 are dug, and can also increase the strength and supporting force of the manhole cover 1.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
