Description

Technical Field

[0001] The utility model relates to the field of municipal engineering, and more specifically, to a road drainage structure for municipal engineering. Background Art

[0002] Municipal road drainage refers to the measures taken to drain the accumulated water on the road surface. Usually, the road surface water converges into the street gutter according to the slope of the road surface. The road drainage structure includes a drainage frame and a drainage cover. A number of drainage grooves are opened on the drainage cover. The drainage cover is detachably connected to the inner wall of the top of the drainage frame. The accumulated water flows from the street gutter into the drainage frame through the drainage grooves on the drainage cover, and then is discharged from the water outlet of the drainage frame into the sewer, and then discharged into the nearby sewage pool or water bodies such as rivers, lakes, and seas.

[0003] The existing road drainage structure usually uses a drainage frame for drainage. In order to prevent the drainage frame from being blocked by a large amount of garbage, a filter screen is generally provided in the drainage frame to filter the garbage. However, after each time the filter screen filters the garbage, in order not to affect the normal use of the filter screen, the garbage on the filter screen needs to be cleaned. At this time, it is necessary to first remove the drainage cover, then take out the filter screen from the drainage frame and collect and clean the garbage on the filter screen, making the process of cleaning the filter screen relatively inconvenient.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0005] Aiming at the deficiencies existing in the prior art, the purpose of the present utility model is to provide a road drainage structure for municipal engineering.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: A road drainage structure for municipal engineering, including a drainage frame and a drainage cover. A filter plate with a trapezoidal cross-section is provided on the inner wall of the drainage frame. The filter plate is located below the drainage cover, and the inclined surface of the filter plate faces the drainage cover. A collection frame is detachably connected in the drainage frame along the vertical direction. The height of the side of the filter plate close to the collection frame is lower than the height of the side away from the collection frame, and a limiting mechanism is provided between the collection frame and the drainage frame to limit their relative positions.

[0007] The present utility model is further provided as follows: A connecting plate that fits with the drainage cover is fixedly connected to the inner wall of the drainage frame, and an L-shaped plate that fits with the filter plate is fixedly connected to the inner wall of the drainage frame. The collection frame abuts against the inner end surface of the L-shaped plate.

[0008] The present utility model is further configured as follows: The limiting mechanism includes a dovetail bar fixedly connected to the outer wall of the collection box and a dovetail groove opened on the inner wall of the collection box. The dovetail bar is slidably connected in the dovetail groove. A cover plate that fits against the connecting plate is fixedly connected to the dovetail bar. There is a gap between the top outer wall of the dovetail bar and the inner wall of the dovetail groove for taking the cover plate.

[0009] The present utility model is further configured as follows: A number of limiting blocks are fixedly connected to the side wall of the drainage cover, and a number of limiting grooves for the limiting blocks to be embedded are opened on the inner wall of the drainage frame.

[0010] The present utility model is further configured as follows: A number of connecting rods are detachably connected between the drainage cover and the filter plate.

[0011] The present utility model is further configured as follows: External threads are provided on the outer peripheral walls at both ends of the connecting rod. A number of threaded holes for the threaded connection of one end of the connecting rod are opened on the filter plate. A number of through holes for the connecting rod to pass through are opened on the drainage cover. And a nut that fits against the end face of the drainage cover is threadedly connected to the end of the connecting rod.

[0012] The present utility model is further configured as follows: A number of water permeable grooves are opened at the bottom of the collection box, and a number of through grooves communicating with the water permeable grooves are opened on the horizontal limb part of the L-shaped plate.

[0013] In summary, the present utility model has the following beneficial effects: When the accumulated water and garbage both flow into the drainage frame through the drainage cover, the accumulated water will continue to flow downward into the sewer through the filter plate, and the garbage will be blocked by the filter plate. Because the cross-section of the filter plate is trapezoidally arranged, and the height of the side of the filter plate close to the collection box is lower than the height of the side far from the collection box, the garbage can gradually slide downward along the inclined surface of the filter plate until the garbage slides into the collection box, so that the garbage will not accumulate on the filter plate all the time, reducing the situation that the filter plate is blocked due to garbage accumulation on the filter plate. At the same time, the collection box stores the garbage. When the garbage in the collection box is stored to a certain amount, only need to hold and take out the collection box upward, and take out the collection box from the drainage frame, so as to facilitate the treatment of the garbage in the collection box.

Because the cross-section of the filter plate 2 is set in a trapezoidal shape, and the height of the side of the filter plate 2 close to the collecting frame 3 is lower than the height of the side away from the collecting frame 3, the garbage can gradually slide downward along the inclined surface of the filter plate 2 until the garbage slides into the collecting frame 3, so that the garbage will not be accumulated on the filter plate 2 all the time, reducing the situation where the garbage accumulates on the filter plate 2 and causes blockage of the filter plate 2, and the collecting frame 3 stores the garbage. When the garbage in the collecting frame 3 is stored to a certain amount, the collecting frame 3 can be taken out of the drainage frame 101 by holding and taking out the collecting frame 3 upward, so as to facilitate the disposal of the garbage in the collecting frame 3.

[0020] like Figure 1 and Figure 2As shown, a connecting plate 4 that fits with the drain cover 102 is pre-embedded and installed on the inner wall of the drain frame 101, and an L-shaped plate 5 that fits with the filter plate 2 is pre-embedded and installed on the inner wall of the drain frame 101, there is a gap between the connecting plate 4 and the L-shaped plate 5, the inner end surface of the collecting frame 3 and the L-shaped plate 5 conflict with each other, the limiting mechanism includes a dovetail bar 61 welded on the outer wall of the collecting frame 3 and a dovetail groove 62 opened on the inner wall of the collecting frame 3, the dovetail bar 61 is slidably connected in the dovetail groove 62, a cover plate 7 that fits with the connecting plate 4 is welded on the dovetail bar 61, there is a gap for taking the cover plate 7 between the top outer wall of the dovetail bar 61 and the inner wall of the dovetail groove 62, and the drain cover 102 and the cover plate 7 are both connected to the drain frame 101 when the drainage structure is draining. The inner wall of the L-shaped plate 5 contacts with the end face of the connecting plate 4, and the collecting frame 3 is stably placed on the L-shaped plate 5 and contacts with the inner wall of the drainage frame 101, thereby improving the stability of the collecting frame 3 in the drainage frame 101. When the garbage in the collecting frame 3 is stored to a certain amount and needs to be cleaned, the user inserts his fingers into the gap between the dovetail bar 61 and the dovetail groove 62 and clamps the dovetail bar 61, moves the dovetail bar 61 upward to drive the cover plate 7 and the collecting frame 3 to move upward, and the dovetail bar 61 gradually disengages from the dovetail groove 62 until the collecting frame 3 is disengaged from the drainage frame 101, thereby processing the garbage in the collecting frame 3, so that when the collecting frame 3 is taken out of the drainage frame 101, only the cover plate 7 is disengaged from the drainage frame 101, so that there is no need to disassemble the entire drainage frame 101, which is more labor-saving.

[0021] like Figure 1 As shown, the drain cover 102 and the filter plate 2 are detachably connected with a plurality of connecting rods 9, and the outer peripheral walls at both ends of the connecting rods 9 are provided with external threads. The filter plate 2 is provided with a plurality of threaded holes 10 for threading one end of the connecting rods 9, and the drain cover 102 is provided with a plurality of through holes for the connecting rods 9 to pass through, and the ends of the connecting rods 9 are threadedly connected with nuts 11 that fit the end surface of the drain cover 102. When the drain cover 102 or the filter plate 2 is damaged and needs to be replaced, the drain cover 102 can be removed by lifting it upwards. Leave the drain frame 101, and in the process of moving the drain cover 102 upward, the connecting rod 9 and the filter plate 2 are also driven to move until the connecting rod 9 and the filter plate 2 are both out of the drain frame 101, and then the nut 11 is first screwed to disengage it from the end of the connecting rod 9, and then the drain cover 102 is removed first to disengage one end of the connecting rod 9 from the through hole on the drain cover 102, and finally the connecting rod 9 is rotated to disengage the external thread on the end thereof from the threaded hole 10 on the filter plate 2, thereby facilitating partial replacement of the drain cover 102 or the filter plate 2.

[0022] like Figure 1As shown in the figure, a plurality of water permeable grooves 12 are formed at the bottom of the collection box 3, and a plurality of through grooves 13 communicating with the water permeable grooves 12 are formed in the horizontal limb portion of the L-shaped plate 5. When the garbage slides down along the inclined surface of the filter plate 2 into the collection box 3, since some accumulated water will also slide down along the inclined surface of the filter plate 2 into the collection box 3, at this time, the accumulated water can first pass through the water permeable grooves 12 and then through the through grooves 13, so as to continue to flow downward, preventing the accumulated water from accumulating in the collection box 3. Thus, when taking out the collection box 3, it is possible to avoid taking out the accumulated water in the collection box 3 at the same time, reducing the weight when taking out the collection box 3.
