[0024] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See attached Figure 1 and Figure 2 A municipal road manhole cover of this embodiment includes a manhole cover body 1. The manhole cover body 1 is a circular structure and is made of ductile iron material. Ductile iron has excellent properties such as high strength, high toughness, wear resistance and corrosion resistance, and can ensure the long-term use of the manhole cover body 1 under heavy traffic and harsh environments. At the same time, the outer surface of the manhole cover body 1 is processed with an anti-slip texture. The anti-slip texture increases the friction of the manhole cover surface, prevents pedestrians and vehicles from sliding on the manhole cover, and improves safety.

[0027] See attached Figure 1 and Figure 5 A plurality of water outlet holes 2 are evenly arranged on the manhole cover body 1, a connecting shaft 3 is rotatably installed in the middle position of the manhole cover body 1, the connecting shaft 3 is longitudinally arranged, a hand wheel 4 is fixedly installed on the top of the connecting shaft 3, and a shielding plate 5 equal to the number of the water outlet holes 2 is fixedly installed on the bottom of the connecting shaft 3, and the water outlet holes 2 and the shielding plates 5 are both fan-shaped structures. The cooperation of the connecting shaft 3 and the shielding plates 5 realizes the opening and closing control of the water outlet holes 2, ensuring that the manhole cover body 1 can drain water when needed and prevent debris from entering when not needed.

[0028] See attached Figure 4 The bottom of the manhole cover body 1 is fixedly installed with limit blocks 7 equal to the number of water outlet holes 2. The limit blocks 7 limit the rotation angle of the shielding plate 5 to ensure that the shielding plate 5 does not move excessively during the rotation process.

[0029] See attached Figure 4 A limiting ring 6 is fixedly installed at the bottom of the manhole cover body 1, and the limiting ring 6 is arranged below the baffle plate 5, and the inner diameter of the limiting ring 6 is smaller than the diameter of the baffle plate 5, which prevents the baffle plate 5 from separating from the manhole cover body 1 during rotation, further enhancing the safety of the manhole cover.

[0030] See attached Figure 1-Figure 3A receiving groove 8 is provided in the middle of the manhole cover body 1, and the hand wheel 4 is arranged in the receiving groove 8. A protective cover 9 is detachably installed in the receiving groove 8, and the protective cover 9 protects the hand wheel 4 to prevent damage to the hand wheel 4 by external factors.

[0031] See attached Figure 1-Figure 3 , mounting grooves 10 are opened on both sides of the water outlet 2 at the top of the manhole cover body 1, and a filter plate 11 is arranged outside the water outlet 2. The filter plate 11 can filter out the debris entering the well, ensuring that only liquid can flow out through the water outlet 2 to prevent blockage, and the filter plate 11 is made of stainless steel material. The stainless steel material has excellent corrosion resistance, which can ensure that the filter plate 11 will not be corroded during long-term use and is easy to clean and maintain. Mounting blocks 12 compatible with the mounting grooves 10 are fixedly installed on both sides of the filter plate 11. The design of the mounting grooves 10 and the mounting blocks 12 makes the filter plate 11 easy to install and disassemble, and convenient for cleaning and maintenance.

[0032] When the municipal road manhole cover is actually used, the water outlet 2 on the manhole cover body 1 is opened and closed by the cooperation of the connecting shaft 3 and the baffle plate 5: when drainage is required, the connecting shaft 3 drives the baffle plate 5 to rotate by turning the hand wheel 4, thereby opening the water outlet 2; when drainage is not required, the hand wheel 4 is turned in the opposite direction to make the baffle plate 5 cover the water outlet 2, and the filter plate 11 is installed outside the water outlet 2 to filter out debris entering the well, ensuring that only liquid can flow out through the water outlet 2.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
