The crank slider mechanism 3 includes a link assembly 6 connected to the output end of the driving motor 4, and a slider 5 disposed on the link assembly 6 and mounted on the slide rail 2, the slider 5 being connected to the grid plate 1.

Specifically, the driving motor 4 can drive the sliding block 5 to reciprocate back and forth along the sliding rail 2 through the connecting rod assembly 6, and the sliding block 5 drives the grid plate 1 to move together, so that the grid plate 1 can also reciprocate back and forth under the driving of the driving motor 4. Wherein, the sliding block 5 and the grid plate 1 can be connected together by welding or screws, and the connecting rod assembly 6 belongs to the prior art of the structure of the crank sliding block 5, and will not be described herein.

In the present embodiment, the drain hole 11 is a straight through hole penetrating the louver 1, and the direction of the drain hole 11 coincides with the moving direction of the slider 5, as shown in fig. 2. In the arrangement, the drain hole 11 is a straight-line-shaped channel and is consistent with the movement direction of the sliding block 5; therefore, when the driving motor 4 drives the grid plate 1 to move forwards and backwards, the problem that the drain holes 11 are completely blocked can be effectively avoided, and the drainage performance of the rainwater grid is ensured.

Meanwhile, as shown in fig. 2, in the present embodiment, the slide rail 2 is provided with a slide rail 7 for the front-rear movement of the slider 5, and a first opening 8 which is in correspondence with the direction of the slide rail 7 and communicates therewith. In a specific connection process, the connecting rod assembly 6 can be connected to the sliding block 5 through the first opening 8, so that interference between the connecting rod assembly 6 and the sliding rail 2 is avoided. In addition, the slide rail 2 is further provided with a limiting opening 9 which is consistent with the direction of the slide rail 7 and communicated with the slide rail, and the slide block 5 is provided with a limiting part 10 which is inserted into the limiting opening 9. The cooperation of the limiting part 10 and the limiting opening 9 can limit the backward movement amplitude of the sliding block 5, so that the condition that the grid plate 1 and the sliding block 5 interfere with each other in the movement process and the installation position in practical application is avoided.

In addition, in the present embodiment, the driving motor 4 is a variable frequency speed motor. In actual operation, when sundries accumulated on the grid plate 1 are increased, the driving motor 4 can adaptively adjust the rotation speed and torque force, so that the problem that the driving motor 4 moves back and forth without moving the grid plate 1 is avoided.

Of course, in another embodiment, the rain grate may include a processing mechanism and a pressure sensor, the pressure sensor being used to detect the amount of accumulation, the sensor being capable of transmitting information about the amount of accumulation to the processing mechanism, the processing mechanism controlling the drive motor 4 to rotate at a preset rotational speed and torque. Wherein, the parameters of the sensor enable the control mechanism to control the driving motor 4 to work in different states, which belongs to the prior art means in the field and is not described herein. The driving motor 4 does not drive the louver 1 to reciprocate all the time, but the driving motor 4 drives the louver 1 to reciprocate when the deposit is deposited to a certain extent.

In fig. 3, P refers to the rain grate of the present embodiment, and Q refers to the mounting surface. When the accumulated water flows through the mounting surface Q, the accumulated water can be discharged through the rainwater grate. Of course, fig. 3 is only a schematic installation diagram of the present embodiment, and in the actual installation process, the driving motor 4 is installed on the installation surface. In addition, fig. 3 is only an installation mode of the rain grate in an environment, and the rain grate can be installed in other needed installation environments according to requirements, which is not described herein.

Through the above-mentioned technical scheme of this embodiment, the rainwater grate of present case passes through the reciprocating motion of grid tray 1, can effectively avoid the problem that the wash port 11 of grid tray 1 was plugged up by debris such as weeds and branch, and the silt of piling up simultaneously can be followed wash port 11 under the motion of grid tray 1 and discharged, guarantees the effective drainage of rainwater grate.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations of the present invention will be apparent to those skilled in the art.
