Technical Field

The utility model belongs to the technical field of sewage treatment's technique and specifically relates to a dirty separation well of ramp inlet for stom water anti-clogging rain is related to.

Background

The urban ecological problem has brought serious challenges to the sustainable development of cities, and people hope to change the severe urban environment through the ecological effect of gardens, so that urban ecological gardens grow. Gardens are human-oriented, natural environment-based, ecological virtuous cycle human living forms, wherein a large number of greenbelts are provided and roads are used, and people can rest in gardens after work. Due to the relative closeness and large area of gardens, the amount of daily rainwater produced by the gardens is relatively large, and targeted treatment is required.

Gardens rainwater is compared in road rainwater, it is many to have the leaf of carrying, the many characteristics of branch, can see in daily, gardens road's rainwater is by the height to low flowing and comparatively torrential on slope, and during the drainage well of inflow road side, a large amount of branches will the joint on the rainwater grate, the rivers that flow over the rainwater grate will be filtered by the branch, branch and leaf in the rivers will be held by the rainwater grate department and accumulate gradually, can't flow away or flow into in the drainage well along with the rivers, lead to the well head to take place to block up.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, one of the purposes of the utility model is to provide a can prevent on domatic that branch leaf from taking place the ramp inlet for stom water that blocks up to the well head and prevent blockking up dirty separation well of rain.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a dirty separation well of slope inlet for stom water anti-clogging can prevent that branch leaf from taking place to block up to the well head of offal well 1, including setting up the rainwater grate 2 of offal well 1 on slope 8 and top surface and 8 surface parallel and levels in slope.

The lower water shaft 1 is opened in the vertical direction, and in the present embodiment, the cross section of the lower water shaft 1 in the horizontal direction is square. The opening of the lower water shaft 1 on the slope is provided with a step groove 11, and the opening direction of the step groove 11 is vertical to the road surface. In the present embodiment, the section of the stepped groove 11 on the road surface is square, and one diagonal line faces the uphill direction, and the other diagonal line is perpendicular to the uphill direction.

The rainwater grate 2 is arranged in a square shape and is arranged on the first step of the stepped groove 11, in the embodiment, the rainwater grate 2 is made of a metal material, and the surface of the rainwater grate is provided with an anti-oxidation layer. The top surface of the rainwater grate 2 is flush with the slope surface, and a plurality of waist-shaped holes 21 for water flow to pass through are arranged in a penetrating way, and the waist-shaped holes 21 are arranged in an array. The side surface of the rain water grate 2 is provided with a water-permeable side groove 22 communicated with the waist-shaped hole 21, and the water-permeable side groove 22 is also waist-shaped. When rainwater flows through the side surface of the rainwater grate 2, leaves and branches can directly rush into the water-permeable side grooves 22 along the water flow and then flow into the sewer shaft 1 through the waist-shaped hole 21.

The bottom surface of the rainwater grate 2 is provided with two water-absorbing expansion water-stop strips 23 which are abutted against the stepped groove 11, the water-absorbing expansion water-stop strips 23 are respectively positioned on two side edges of the bottom surface of one corner of the rainwater grate 2 facing the upward slope direction, and the thickness of the water-absorbing expansion water-stop strips 23 facing the upward slope direction is gradually increased. Be provided with filler strip 12 on the ladder groove 11 for raise rainwater grate 2 and be close to one side of downhill path, with the surface and the domatic parallel and level of guaranteeing rainwater grate 2, avoid passerby to trample at ordinary times and take place the risk of jolting on it. The angle of the rainwater grate 2 towards the upslope direction is a water attack angle, when water flows through, the water absorption expansion water stop bar 23 absorbs water to expand, one side of the water attack angle of the rainwater grate 2 is lifted above the road surface, and the rainwater grate is gradually increased in the upslope direction. At the moment, branches flowing downwards along with water flow are blocked by the side surfaces of the rainwater grate 2 and are divided to two sides by the water-facing angle, and compared with the arrangement that one side surface is perpendicular to the water flow direction, the situation that the protruding side surface blocks the branches transversely can not occur. After the rain strainer 2 runs across the sunny day, the water absorption expansion water stop bars 23 lose water and are lowered until the top surface of the rain strainer 2 is flush with the slope surface again, and therefore the pedestrians are prevented from being tripped over.

Referring to fig. 2, the bottom of the sewage shaft 1 is provided with a sand holding box 3 and a container 4 for containing the sand holding box 3, in this embodiment, the container 4 is a square groove, the sand holding box 3 is a box with a square block shape and an upper opening, and the depth of the container 4 is greater than the height of the sand holding box 3. The sand box 3 is excessively engaged with the container 4 in the container 4.

The edge of the opening of the accommodating groove 4 is rotatably connected with a blocking eave strip 5, and the blocking eave strip 5 is fixed with the side wall of the accommodating groove 4 through a clamping device 6. In this embodiment, the blocking eave strip 5 is a triangular rib made of a stainless steel material, one corner of the blocking eave strip 5 is hinged to the edge of the opening of the accommodating groove 4, and one end surface of the blocking eave strip 5 abuts against the side wall of the accommodating groove 4. The section of the blocking eave strip 5 perpendicular to the axis is in the shape of an isosceles right triangle, when a right-angle side surface abuts against the side wall of the stepped groove 11, the other right-angle side surface is perpendicular to the side wall of the stepped groove 11, and the nearest distance of the blocking eave strip 5 on the opposite side wall of the containing groove 4 is smaller than the width of the sand containing box 3 between the opposite side walls. The clamping device 6 comprises a fixed seat 61 arranged on the wall of the accommodating groove 4 and a bolt 62 penetrating through the fixed seat 61 and used for preventing the eave strip 5 from rotating, in the embodiment, the bolt 62 is positioned on the rotation path of the eave strip 5, when the bolt 62 is inserted into the fixed seat 61, the bolt 62 abuts against the eave strip 5 and prevents the eave strip 5 from rotating, and at the moment, the distance between the side edges close to the near side on the opposite eave strip 5 is smaller than the width of the sand containing box 3 between the opposite side walls where the opposite eave strip 5 is located, so that the eave strip 5 prevents the sand containing box 3 from falling off. When the sand in the sand containing box 3 needs to be cleaned, the blocking eaves strip 5 can be released only by pulling out the bolt 62 on the fixed seat 61. The blocking eave strip 5 is turned over towards the outside of the containing groove 4 until the blocking eave strip 5 abuts against the pipe wall of the sewer pipeline, so that the sand box 3 is not blocked from being taken out.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
