Implementation

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1A municipal engineering road drainage structure in this embodiment includes a road body 1, an installation groove 2 is opened on the upper surface of the road body 1, and a drainage port 3 is opened on the inner bottom wall of the installation groove 2 to facilitate the passage of water into the sewer pipe. A cover plate 4 is placed on the inner bottom wall of the installation groove 2, and a drainage pipe 5 is fixed on the lower surface of the cover plate 4. A partition mechanism 6 for blocking the odor of the sewer is arranged inside the drainage pipe 5 to prevent the odor inside the sewer from being discharged when there is no drainage. A placement groove 7 is opened on the upper surface of the cover plate 4, and a filtering mechanism 8 for filtering large-volume residues in the drainage is arranged inside the placement groove 7 to prevent large-volume impurities from being discharged into the sewer pipe and causing blockage of the sewer pipe.

[0023] The length and width of the cover plate 4 are respectively matched with the length and width of the installation groove 2 , and the length and width of the cover plate 4 are respectively greater than the length and width of the drain port 3 .

[0024] See also Figure 2 In order to prevent the discharge of odor inside the sewer when there is no drainage, the partition mechanism 6 in this embodiment includes a mounting frame 601 fixed to the inner wall of the left side of the drain pipe 5, and a rotating rod 602 is rotatably connected between the inner walls on the opposite side of the mounting frame 601 through a bearing, and a partition plate 603 is fixed on the outer side of the rotating rod 602. The rotating rod 602 can make the partition plate 603 rotate, thereby opening the drain pipe 5. Torsion springs 604 are fixed between the front and rear sides of the partition plate 603 and the inner walls of the front and rear sides of the mounting frame 601, respectively. The downward flow of water will generate an impact force, and the impact force of the water flow acts on the partition 603, causing the partition 603 to rotate. The rotation of the partition 603 drives the torsion spring 604 to stretch, so that the partition 603 opens, allowing the water to flow from the drain pipe 5 into the drain outlet 3. The limiting plate 605 is fixed to the left inner wall of the drain pipe 5. After drainage is completed, the torsion spring 604 loses the effect of external force and will bounce the partition 603 back to the position of the limiting plate 605. The limiting plate 605 can keep the partition 603 at a horizontal angle.

[0025] In this example, there are two mounting frames 601 and two limiting plates 605, which are symmetrically distributed about the central axis of the drain pipe 5. The length of the partition 603 is adapted to the distance between the front and rear inner walls of the mounting frame 601, and is adapted to the distance between the front and rear inner walls of the drain pipe 5. The sum of the widths of the two partitions 603 is adapted to the distance between the left and right inner walls of the drain pipe 5, so as to isolate the drain pipe 5 to the greatest extent and prevent the gas inside the sewer pipe from floating out.

[0026] See also Figure 3-4In order to prevent larger impurities from being discharged into the sewer pipe and causing blockage to the sewer pipe, the filtering mechanism 8 in this embodiment includes a supporting plate 801, which is placed on the inner bottom wall of the placement groove 7, and a connecting port 802 is provided on the inner bottom wall of the placement groove 7. A filter screen 803 is fixed to the lower surface of the supporting plate 801 by bolts, and the filter screen 803 is located inside the connecting port 802. A water through hole 804 is provided on the upper surface of the supporting plate 801. Water flows from the water through hole 804 to the lower part of the supporting plate 801. At this time, some larger impurities carried in the water flow will be filtered out by the filter screen 803, so as to prevent these impurities from flowing into the sewer pipe and causing blockage to the sewer pipe. A handle 805 is fixed to the upper surface of the supporting plate 801. After draining, the cleaning staff can drive the supporting plate 801 to move by the handle 805, and the supporting plate 801 drives the filter screen 803 to move, so that the filter screen 803 is taken out. After taking it out, the bolts are removed, and the impurities filtered out of the filter screen 803 can be cleaned.

[0027] In this example, the length and width of the support plate 801 are respectively matched with the length and width of the placement groove 7, and the length and width of the filter net 803 are respectively matched with the length and width of the connecting port 802, so as to facilitate the placement of the support plate 801 and prevent the support plate 801 from falling into the drain pipe 5. The number of water holes 804 is not less than two and is evenly distributed on the upper surface of the support plate 801 to speed up the drainage.

[0028] The working principle of the above embodiment is:

[0029] (1) On rainy days, rainwater falls on the ground. If the water is not drained away in time, the rainwater remaining on the road surface will seriously affect traffic. Therefore, a drainage structure is required. When there is water on the road surface, the water will flow to the cover plate 4. When the water flows to the surface of the cover plate 4, it will flow from the water hole 804 to the bottom of the support plate 801. At this time, some large impurities carried in the water will be filtered out by the filter 803 to prevent these impurities from flowing into the sewer pipe and causing blockage of the sewer pipe. After the drainage is completed, the cleaning staff can use the handle 805 to drive the support plate 801 to move, and the support plate 801 drives the filter 803 to move, so that the filter 803 can be taken out. After taking it out, the bolts can be removed, and the impurities filtered out of the filter 803 can be cleaned.

[0030] (2) During the drainage process, water flows into the drain pipe 5. The downward flow of water will generate an impact force. The impact force of the water acts on the partition 603, causing the partition 603 to rotate. The rotation of the partition 603 drives the torsion spring 604 to stretch, causing the partition 603 to open, allowing the water to flow from the drain pipe 5 into the drain port 3 and finally into the sewer pipe below. After the drainage is completed, the torsion spring 604 loses the effect of the external force and will bounce the partition 603 back to the position of the limit plate 605. The limit plate 605 can keep the partition 603 at a horizontal angle, thereby isolating the drain pipe 5 to the greatest extent and preventing the gas inside the sewer pipe from floating out.
