[0002] SMC molded manhole cover, a new type of colorful high-strength manhole cover, is molded using advanced technology and equipment. After being tested by the National FRP Quality Supervision and Inspection Center of the Ministry of Construction, the heavy-duty manhole cover has a load-bearing capacity of over 400KN, far exceeding the national standard of 240KN. At the same time, after being tested by the National FRP Quality Supervision and Inspection Center, its anti-aging index far exceeds the national standard.

[0003] When using the trench cover, most of them have larger drainage grooves. However, some trench covers have larger drainage grooves for quick drainage, which may lead to animals such as rodents entering the drainage pipe through the drainage grooves. Some trench covers also have smaller drainage grooves, but the sewage flow is slow. However, impurities in the sewage can easily clog the drainage grooves, making it inconvenient to clean and not easy to drain quickly. It is very inconvenient to use. Therefore, we need to propose an SMC molded trench cover. Utility Model Content

[0027] See also Figure 1-5 The utility model provides a technical solution: an SMC molded trench cover, including an upper cover 1, a connecting assembly 3 and a loading and unloading assembly 9. A lower cover 2 is arranged below the upper cover 1, and a water leakage hole is opened on the lower cover 2. A drainage groove 5 is opened on the top of the upper cover 1. A filter screen 8 is arranged inside the upper cover 1. Sewage is discharged through the drainage groove 5. Impurities contained in the sewage are filtered through the filter screen 8 to prevent clogging of the drainage pipe and ensure the fluidity of the sewage. When cleaning the filter screen 8, the upper cover 1 and the lower cover 2 can be removed, which is convenient and easy to operate.

[0028] Furthermore, a handle 4 is welded on the top of the upper cover plate 1 to facilitate taking out the upper cover plate 1 .

[0029] Furthermore, the drainage trough 5 is connected with a horizontal bar 6 and a vertical bar 7. By using the horizontal bar 6 and the vertical bar 7, the opening of the drainage trough 5 is prevented from being too large, thereby preventing animals such as rodents from entering. Example

[0030] See also Figure 1-4 On the basis of the first embodiment, the connection component 3 is located between the upper cover plate 1 and the lower cover plate 2. The connection component 3 includes a plug rod 301, a socket 302, a block 303 and a card slot 304. The plug rod 301 is welded and installed on the bottom of the upper cover plate 1, and the socket 302 is fixedly connected to the top of the lower cover plate 2. The socket 302 is provided with a socket, and the plug rod 301 and the socket are embedded.

[0031] Furthermore, blocks 303 are welded and installed on the outer walls of both sides of the insertion rod 301, and a card slot 304 is opened on the socket 302. The card slot 304 and the block 303 are configured for card connection. By using the block 303 and the card slot 304, the fixity of the connection between the upper cover plate 1 and the lower cover plate 2 is improved.

[0032] Adjacent inner walls of the upper cover plate 1 are provided with slide grooves, in which connecting blocks 11 are slidably installed, and in which return springs 10 are installed, and the free ends of the return springs 10 are fixedly connected to the connecting blocks 11. When the amount of sewage is large, the sewage will impact the filter screen 8, and the filter screen 8 will move up and down when pressed down by the return spring 10, which can shake the filter screen 8 to prevent impurities from clogging the filter screen 8.

[0033] The loading and unloading assembly 9 is located inside the upper cover plate 1. The loading and unloading assembly 9 is divided into two groups and is symmetrically arranged. The loading and unloading assembly 9 includes a shell 901, a compression spring 902, a slider 903, a clamping column 904, a second clamping slot 905 and a pull rod 906. The shell 901 is installed on the top and bottom of the filter 8. The compression spring 902 is fixedly installed on the inner wall of one side of the shell 901. The slider 903 is slidably installed inside the shell 901. The free end of the compression spring 902 is fixedly connected to one side of the slider 903. The other side of the slider 903 is fixedly installed with a clamping column 904. Column 904 and connecting block 11 are provided with a second card slot 905, and the column 904 and the second card slot 905 are configured for card connection. A pull rod 906 is welded and installed between the two sets of sliders 903. When the filter 8 needs to be disassembled, the pull rod 906 is pulled, and the pull rod 906 drives the slider 903 horizontally. At this time, the slider 903 squeezes the compression spring 902, so that the card column 904 and the second card slot 905 cancel the card connection, and the filter 8 can be disassembled, which is convenient for cleaning and replacement of the filter 8, ensuring the filtering effect of the filter 8 and convenient for use.

[0034] When in use, the upper cover plate 1 and the lower cover plate 2 are connected by a snap-fitting manner, the sewage is discharged through the drainage groove 5, and the impurities contained in the sewage are filtered through the filter screen 8 to prevent clogging of the drainage pipe. When the amount of sewage is large, the sewage will impact the filter screen 8, and the filter screen 8 will move up and down under the use of the return spring 10, which can shake the filter screen 8 to prevent impurities from clogging the filter screen 8;

[0035] By using the horizontal bar 6 and the vertical bar 7, the opening of the drainage trough 5 is prevented from being too large, thereby preventing animals such as rodents from entering;

[0036] When the filter 8 needs to be disassembled, pull the pull rod 906, and the pull rod 906 drives the slider 903 horizontally. At this time, the slider 903 squeezes the compression spring 902, so that the clamping column 904 and the second clamping slot 905 cancel the clamping setting, and the filter 8 can be disassembled, which is convenient for cleaning and replacement of the filter 8 and ensures the filtering effect of the filter 8. During installation, align the clamping column 904 and the second clamping slot 905 for clamping.
