Technical Field

[0001] The utility model relates to the technical field of drainage equipment, and in particular to a high-strength ductile iron grate. Background Art

[0002] There are many underground pipelines in urban construction, such as sewers, water pipes, power pipes, communication pipes, etc. These pipes must have an outlet to the ground at intervals. At the outlet on the ground, grates or manhole covers are often needed to cover them to reduce the impact on vehicles and pedestrians. Many existing rainwater grates are made of flat steel and twisted square steel or flat steel and flat steel welded together, as well as made of ductile iron. Ductile iron grates have the advantages of beautiful appearance, optimal drainage, high strength, multiple specifications and low cost.

[0003] Many existing ductile iron grates are usually fixed with a net underneath during daily use to prevent items from falling into the drain pipe. However, during the rainy season, too many debris such as dead branches and leaves are easily accumulated on the grates with the net fixed on them, which may lead to waterlogging due to poor drainage. The commonly used drainage method is to open the rainwater grate to speed up the drainage. However, after the rainwater grate is opened, it is easy for debris such as dead branches and leaves to block the drain pipe. Therefore, those skilled in the art provide a high-strength ductile iron grate to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model proposes a high-strength ductile iron grate, which can easily be disassembled and assembled by sliding the filter plate and setting the net, so that the drainage speed can be guaranteed while reducing the occurrence of debris such as dead branches and leaves in the drainage pipe, thereby solving the above-mentioned problem.

[0006] Preferably, the cross sections of the two groups of sliding grooves and the two groups of sliding bars are both trapezoidal in shape.

[0007] Preferably, a groove handle is provided at the middle position of the right outer wall of the filter plate.

[0008] Preferably, fixed blocks are fixedly installed at the front and rear end edges of the right side outer wall of the water screen plate, and slots are opened on the installation frame at the corresponding positions of each group of the fixed blocks, and each group of the fixed blocks is engaged and connected with the slots at the corresponding positions.

[0009] Preferably, anti-falling plates are fixedly installed at the bottom ends of the four corners inside the installation frame.

[0010] Preferably, two groups of first mounting grooves are symmetrically opened inside the mounting frame, and a fixing column is fixedly installed at the bottom end of each group of the first mounting grooves. A bag net is provided under the mounting frame, and connecting blocks are fixedly installed at the bottom end of the bag net and the corresponding positions of each group of the first mounting grooves. Each group of the connecting blocks is provided with mounting holes corresponding to the fixing columns, and each group of the fixing columns is engaged and connected with the mounting holes at the corresponding positions.

[0011] Preferably, an anti-fall-off clamp is fixedly installed on the top of each group of fixing columns.

[0012] Preferably, a second mounting groove is provided on the right side of the top end of the water-passing screen plate, and a handle is longitudinally rotatably mounted on the left inner wall of the second mounting groove.

[0013] The working principle and beneficial effects of the utility model are as follows:

[0014] When using this device in daily life, the staff can slide the filter plate to the bottom of the water-passing screen plate, so that the device can not only pass water, but also block debris such as dead branches and leaves. At the same time, it can also prevent people's mobile phones or keys and other items from accidentally falling into the drain pipe. In addition, when the drainage volume is too large in the rainy season, the staff can pull out the filter plate and then install the net inside the first installation groove, so that when the water-passing screen plate is discharged, the net can filter, block and collect debris such as dead branches and leaves in the water, thereby reducing the possibility of dead branches and leaves and other debris clogging the drain pipe, thereby making the practical use of this device higher.
