[0007] The lower side of the drain outlet is connected with a water guide wall, one side of the lower end of the water guide wall is equipped with a self-resetting torque hinge, and the other side of the self-resetting torque hinge is connected with a blocking plate.
[0008] Preferably, the side wall and the bottom of the filter frame are penetrated and fixedly connected with a filter screen, and the top of the filter frame is provided with a No. 1 convex edge, and the top of the No. 1 convex edge is symmetrically fixedly installed with a handle.
[0009] Preferably, a No. 2 convex edge is provided at the lower end of the well wall.
[0010] Preferably, a plurality of transverse ribs are fixedly installed on the inner side of the drain outlet.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] The utility model discloses a manhole cover structure for municipal engineering. When in use, the sealing plate is subjected to the pressure of rain water, the self-resetting torque hinge is opened by the external force, and the rain water flows down and enters the sewer. After the rain water enters the wall of the manhole mixed with debris, it faces the screening of the filter screen. The debris that is too large cannot pass through the filter screen and enter the sewer. After the rain stops, the staff can lift out the filter frame for cleaning by means of the lifting handle to ensure the next use. The self-resetting torque hinge and the sealing plate below the drainage port of the manhole cover are in a closed state, while the drainage port of the conventional manhole cover is in a normally open state. The conventional manhole cover cannot prevent the unpleasant odor in the sewer from emanating. The utility model discloses a manhole cover structure for municipal engineering. It can solve the problem that the unpleasant odor in the sewer will overflow through the drainage port when no drainage operation is performed. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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 implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0019] See also Figure 1-4A manhole cover structure for municipal engineering includes a manhole wall 2 and a manhole cover 1 at the top of the manhole wall 2. A plurality of drain ports 12 are longitudinally penetrated on the manhole cover 1 at equal distances in the circumferential direction. A filter frame 3 is installed at the lower end of the manhole wall 2. A water guide wall 13 is connected to the lower side of the drain port 12. A self-resetting torque hinge 14 is installed on one side of the lower end of the water guide wall. A sealing plate 15 is connected to the other side of the self-resetting torque hinge 14. In the working state, the drain port 12 on the manhole cover 1 works normally. Rainwater flows into the water guide wall 13, and the sealing plate 15 blocks it first. After the rainwater pressure exceeds the pressure that the self-resetting torque hinge 14 can withstand, the sealing plate 15 opens, and the water flows through the water guide wall 13 and the sealing plate 15 and flows into the filter frame 3 along the manhole wall 2.
[0020] Furthermore, the side walls and the bottom of the filter frame 3 are penetrated and fixedly connected with a filter screen 31, and a No. 1 convex edge 32 is provided at the top of the filter frame 3. The No. 1 convex edge 32 and the top of the No. 1 convex edge 32 are symmetrically fixedly installed with a handle 33. Rainwater must be mixed with other objects. The filter screen 31 on the side walls and the bottom of the filter frame 3 filters out impurities and allows rainwater to enter the sewer smoothly. The handle 33 can easily lift the filter frame 3.
[0021] Furthermore, a second flange 21 is provided at the lower end of the well wall 2 , and the first flange 32 is placed on the second flange 21 .
[0022] Furthermore, a plurality of transverse ribs 16 are fixedly installed on the inner side of the drain outlet 12. The arrangement of the transverse ribs 16 can block some large impurities carried in the rainwater on the manhole cover 1, thereby reducing the pressure of the filter frame 3 bearing the impurities.
[0023] Working principle: The utility model is a manhole cover structure for municipal engineering. When in use, the sealing plate 15 is subjected to the pressure of rainwater, and the self-resetting torque hinge 14 is opened by external force, and the rainwater flows downstream and enters the sewer. After the rainwater enters the manhole wall 2 mixed with debris, it faces the screening of the filter net 31. Debris that is too large cannot pass through the filter net 31 to enter the sewer. After the rain stops, the staff can lift the filter frame 3 for cleaning through the handle 33 to ensure the next use. The self-resetting torque hinge 14 and the sealing plate 15 under the drain outlet of the manhole cover 1 are in a closed state, while the drain outlet 12 of the conventional manhole cover is in a normally open state. The conventional manhole cover 1 cannot prevent the unpleasant odor in the sewer from emanating, while the self-resetting torque hinge 14 and the sealing plate 15 in the present manhole cover structure can effectively prevent the unpleasant odor in the sewer from overflowing through the drain outlet 12.
[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
