DETAILED DESCRIPTION
[0020] Embodiments, by Figures 1-5 The utility model discloses a frame 1 is fixedly connected with grating plate 2 and overflow plate one 4 in the inside, grating plate 2 is located overflow plate one 4 one side, be provided with V-shaped drainage groove 3 between grating plate 2 and frame 1 inner wall and overflow plate one 4, the top -up mechanism is penetrated and is connected below grating plate 2, overflow plate one 4 divides the overflow port 5 in frame 1 inside, overflow port 5 is located overflow plate one 4 far away grating plate 2 one side, frame 1 top fixedly connected with filter screen plate 7, overflow plate one 4 is located filter screen plate 7 bottom when the grating port on grating plate 2 is blocked by waste, the water that can not be discharged on grating plate 2 can flow to overflow plate one 4 through V-shaped drainage groove 3, finally enters overflow port 5 and discharges.
[0021] The V-shaped drainage groove 3 bottom is flush with the notch low place of overflow plate one 4, overflow plate two 6 is fixedly connected in overflow port 5 inside, overflow plate two 6 is located filter screen plate 7 bottom, and overflow plate two 6 mainly plays the support effect to filter screen plate 7, avoids the person or car on the road and press on filter screen plate 7 and makes it press concave deformation, and simultaneously the modeling of overflow plate two 6 makes it not influence the drainage problem of water filtered down from filter screen plate 7.
[0022] The filter screen plate 7 is provided with a plurality of notches 8 on one side close to the edge of frame 1, the notch 8 is located above overflow port 5, when grating plate 2, V-shaped drainage groove 3 and overflow plate one 4 are all blocked, filter screen plate 7 can also continue to filter water and discharge, and if filter screen plate 7 is also blocked, water can also be discharged through notch 8, and the drainage of multiple points and multiple ways can prevent the problem of well lid blockage affecting drainage to some extent.
[0023] The jacking mechanism comprises a plurality of jacking blocks 10 corresponding to the grating openings of the grating plate 2, two connecting blocks one 11 fixedly connected between left and right adjacent two jacking blocks 10, two connecting blocks two 12 fixedly connected between front and rear adjacent two jacking blocks 10, two hangers 13 fixedly connected at the top of the two connecting blocks two 12, and a handle 14 fixedly connected at the top of the two hangers 13. When the grating openings of the grating plate 2 need to be cleaned, the jacking mechanism can be lifted to jack the waste in the grating openings out through the jacking blocks 10. At this time, the upper surface of the grating plate 2 is a complete plane, and the waste can be quickly cleaned without the need to insert fingers into the grating openings of the grating plate 2 to pick out the waste, which is convenient to operate and avoids the problem of finger injury. The garbage on other parts of the well lid, such as the filter screen plate 7, is also on the surface and can be directly cleaned.
[0024] A recessed groove 15 is formed at the top center of the grating plate 2, the handle 14 is located inside the recessed groove 15, the hangers 13 penetrate the grating plate 2, and a picking groove 16 is arranged on the front and rear inner walls of the recessed groove 15. When the jacking mechanism is not in use, the plurality of jacking blocks 10 are suspended below the grating plate 2 through the hangers 13 and do not affect normal drainage. The handle 14 is embedded in the recessed groove 15 and flush with the upper surface of the grating plate 2, so there is no protrusion to affect the flatness of the road. The picking groove 16 facilitates the fingers to pinch the handle 14 and lift it for use.
[0025] The fence 9 is fixedly connected to the top of the outer side of the frame 1, which can make the frame 1, i.e. the well lid, have better flatness and stability when installed on the road surface.
[0026] Working principle:
[0027] After the well lid is installed, the grating plate 2 and the filter screen plate 7 are flush with the road surface. When it rains or drains, the water on the road surface can be drained from the grating openings of the grating plate 2, or flow from the V-shaped drainage groove 3 to the overflow plate one 4, and finally be drained from the overflow port 5. At the same time, it can also directly pass through the filter screen plate 7 or the gap 8 into the overflow port 5 for drainage. When the drainage volume is too large and some waste such as branches, mud blocks and plastic bags are mixed in the water, the grating plate 2 used for main drainage is easy to be blocked by the waste. The plurality of drainage points and the drainage mode described above can avoid the problem that the traditional single drainage net is blocked and cannot drain water. When the drainage is finished or the waste in the grating openings of the grating plate 2 needs to be cleaned, the fingers can be inserted into the picking groove 16 to pinch the handle 14, and then the handle 14 is lifted out of the recessed groove 15. Subsequently, the plurality of jacking blocks 10 are lifted through the hangers 13 until the hangers 13 jack the waste in the grating openings of the grating plate 2 out and block the grating openings of the grating plate 2. At this time, the waste is on the upper surface of the grating plate 2, and only needs to be pushed away by hand without the need to insert fingers into the grating openings of the grating plate 2 to pick out the waste.
