[0002] When a vehicle passes over a manhole cover, it often makes noise, which not only causes certain noise pollution to the urban environment but also affects the service life of the manhole cover. At present, although some manhole cover products are equipped with rubber strip-like soft pads on the manhole seat to achieve relative silence, the rubber strip installation grooves are all straight grooves. After the rubber strip adheres to the manhole cover, when the manhole cover is opened for cleaning and dredging operations, the rubber strip is easily pulled and broken, and it is not easy to install and restore the rubber strip. The noise and vibration reduction effect of the manhole cover is poor, or the noise and vibration reduction effect is lost, and the service life of the rubber strip is short, resulting in a large waste of resources.

[0036] Embodiment 1:
[0037] Referring to Figures 1 - 2 , as an embodiment of the present invention, a manhole cover with an embedded shock-absorbing strip is proposed, including: a cover plate 1 with an annular groove 101; a frame 2 with a mounting surface 201, and the cover plate 1 is detachably arranged on the mounting surface 201; a sealing strip 3 is arranged on the mounting surface 201, and after the cover plate 1 and the frame 2 are buckled, the sealing strip 3 is located between the annular groove 101 and the mounting surface 201.
[0038] In the above solution, the annular groove 101 is provided at the bottom edge of the cover plate 1, and the opening of the annular groove 101 faces the side of the frame 2. The annular groove 101 is used to accommodate the sealing strip 3. The top surface and both side surfaces of the sealing strip 3 can be attached to the inside of the annular groove 101. Whether the sealing strip 3 receives a downward pressure or a lateral impact force, shock absorption and noise reduction can be achieved, improving the shock absorption and noise reduction effect. During installation, first embed the sealing strip 3 into the annular groove 101 of the cover plate 1. Then place the cover plate 1 on the installation surface 201 of the frame 2 to ensure that the sealing strip 3 is between the annular groove 101 and the installation surface 201, and then fix the cover plate 1 on the frame 2. When it is necessary to open the manhole cover for cleaning or other maintenance work, simply release the fixing device to easily remove the cover plate 1 without worrying about damage to the sealing strip 3. The manhole cover in this embodiment effectively solves the noise problem generated during the use of traditional manhole covers through the design of the embedded sealing strip 3. The embedded design of the sealing strip 3 makes it not easily damaged during the opening and closing of the manhole cover, extending its service life and reducing the maintenance cost. It also simplifies the installation and replacement process of the sealing strip 3, improving work efficiency.
[0039] Further, the installation surface 201 is an annular plane. The sealing strip 3 includes: a protruding portion 302, which is provided in the annular groove 101; a bottom support portion 301, which is provided below the protruding portion 302. The bottom support portion 301 is provided on the installation surface 201. Both side edges of the bottom support portion 301 are located outside the protruding portion 302. The bottom surface of the cover plate 1 abuts against the top surface of the bottom support portion 301.
[0040] In the above solution, in this embodiment, the installation surface 201 is an annular plane, and the sealing strip 3 is integrally placed on the installation surface 201. The advantage is that it is convenient for the installation of the sealing strip 3, and the sealing strip 3 designed in this way is relatively thick. When the manhole cover is squeezed, it can provide better buffering and shock absorption and noise reduction effects, and is suitable for roads with a large traffic flow. Secondly, the sealing strip 3 includes a protruding portion 302 and a bottom support portion 301. The protruding portion 302 can be completely placed in the annular groove 101, and the bottom support portion 301 can provide shock absorption support for the bottom of the annular groove 101, improving the overall shock absorption and noise reduction effect of the cover plate 1 relative to the frame 2.
[0041] Further, the protruding portion 302 has a card slot 4, and further includes: a clamping block 5, which is provided on the cover plate 1 and is located in the annular groove 101. The clamping block 5 is detachably arranged on the card slot 4.
[0042] In the above solution, the clamping block 5 is a rubber clamping block 5 or a cast iron protrusion. The clamping groove 4 is formed on both side walls of the protruding part 302 of the sealing strip 3. After the cover plate 1 is installed on the sealing strip 3, the clamping block 5 in the annular groove will enter the clamping groove 4. At this time, the manhole cover and the sealing strip 3 can play a limiting role. It should be noted that the sealing strip 3 is directly placed, bonded or anchored on the manhole cover. The limiting strip is limited by the manhole cover, which can also prevent the sealing strip 3 from falling off under external force and improve the installation stability of the sealing strip 3.
[0043] Refer to Figure 5 , further, the frame 2 has an installation groove 9, and further includes: a safety net 7, which is detachably arranged in the installation groove 9.
[0044] In the above solution, the safety net 7 can be directly clamped in the installation groove 9. When the cover plate 1 is damaged, it can prevent passers-by from falling into the well, improving the installation performance.
[0045] Further, it further includes: a hinge rod 10, one end of which is hinged to the cover plate 1 and the other end is hinged to the inner wall of the frame 2.
[0046] In the above solution, when the cover plate 1 is opened, the hinge rod 10 can connect the cover plate 1 to prevent the cover plate 1 from accidentally falling off. It can also prevent the cover plate 1 from being stolen.
[0047] Refer to Figure 6 , further, the top surface of the cover plate 1 has an anti-slip pattern 102, and the bottom surface of the cover plate 1 has a reinforcing rib plate 6, and the reinforcing rib plate 6 is located inside the frame 2. The strength and anti-slip effect of the manhole cover are improved.
[0048] Embodiment 2:
[0049] Refer to Figures 3 - 4 , the difference between this embodiment and Embodiment 1 is only that the installation surface 201 of this embodiment is an annular protrusion, the longitudinal section of the sealing strip 3 is strip-shaped, and the sealing strip 3 is arranged between the annular groove 101 and the annular protrusion.
[0050] In the above solution, specifically, the longitudinal section of the sealing strip 3 in this embodiment is rectangular, and the installation surface 201 is an annular protrusion made of cast iron. During installation, only need to first cover the sealing strip 3 on the surface of the annular protrusion, and then buckle the annular groove 101 of the cover plate 1 on the annular protrusion. The installation is convenient and fast. It is suitable for places with low traffic flow and high pedestrian flow.
[0051] Further, the annular protrusion has a limiting groove 8, and the sealing strip 3 further includes: a limiting block 303, which is arranged on the side surface of the sealing strip 3 close to the annular protrusion, and the limiting block 303 is detachably arranged on the limiting groove 8.
[0052] In the above solution, after the sealing strip 3 is installed on the annular protrusion, to prevent the installed sealing strip 3 from warping, the limiting block 303 on the sealing strip 3 can be directly clamped on the annular protrusion during installation, which is convenient for subsequent installation. During use, the limiting block 303 on the sealing strip 3 cooperates with the limiting groove 8 on the annular protrusion, and can also prevent the sealing strip 3 from shifting by itself due to external vibration, thereby improving the shock absorption and noise reduction effect.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
