Description

Technical Field

[0001] The present invention belongs to the technical field of municipal drainage facilities, and in particular relates to a rainwater inlet anti-blocking device and a working method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In urban drainage systems, rainwater grates are crucial components, collecting rainwater from roads. However, in practice, rainwater grates often become clogged with debris such as leaves, plastic bags, and paper scraps. Once clogged, rainwater cannot be drained away in a timely manner, leading to road waterlogging. This not only causes significant inconvenience for pedestrians and vehicles, but can also, in severe cases, cause urban flooding and other disasters, resulting in significant economic losses and safety hazards.

[0004] Currently, the prior art discloses an anti-blocking rainwater outlet, which includes a rainwater outlet and a rainwater grate covering the rainwater outlet, as well as a dead leaf interception device and a dead leaf cleaning device. The dead leaf interception device intercepts dead leaves and debris flowing into the wellbore through the rainwater outlet and drops them into the collection trough below. Although this can solve the problem of preventing the rainwater outlet from being blocked, when the collection trough is full of debris, it is still necessary to manually clean the debris in the rainwater outlet. The manual regular cleaning method is inefficient, labor-intensive, and untimely, making it difficult to meet the needs of rapid urban development and efficient drainage. Therefore, it is of great practical significance to develop an anti-blocking rainwater outlet that can automatically clean debris and keep drainage unobstructed. Summary of the Invention

[0005] In response to the above problems, the present invention provides a rainwater inlet anti-blocking device and a working method thereof, which solves the problem that rainwater inlets are easily blocked. By unifying the debris at the rainwater inlets to the downstream for cleaning, there is no need to dispatch workers to clean each rainwater inlet, which reduces the difficulty of rainwater inlet dredging work and reduces labor costs.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] In the first aspect, the present invention provides a rainwater inlet anti-blocking device, comprising: a curb stone, a stainless steel chain, a driving device, a stainless steel silt clearing rod device, and an external waterproof power supply; a reserved chain groove is provided on the side of the curb stone, and a driving device is provided in the reserved chain groove, and the driving device is connected to the control system for automatically controlling the stainless steel silt clearing rod device to work, and the driving device and the control system are both connected to the external waterproof power supply for providing power to the control system and the driving device, a stainless steel chain is installed on the driving device, and a plurality of stainless steel silt clearing rod devices are provided on the stainless steel chain; a rainwater grate is provided below the stainless steel silt clearing rod device, and a drainage pipe is provided below the rainwater grate, and the driving device drives the stainless steel silt clearing rod device through the stainless steel chain, thereby realizing the cleaning of debris on the rainwater grate.

[0012] As a further implementation, the stainless steel chain is an annular chain, which is driven by the driving sprocket to drive the stainless steel dredging rod device to move back and forth.

[0013] As a further implementation method, the driving device also includes a stepper motor, and the driving sprocket is installed on the driving shaft of the stepper motor to drive the driving sprocket; the stepper motor is connected to the control system to control the stepper motor to work continuously or intermittently; the control system is provided with a signal control module to receive signals from a remote control and control the stop and operation of the driving device through the remote control.

[0014] In a second aspect, the present invention further provides a working method of a rainwater inlet anti-blocking device, which specifically comprises the following steps:

[0015] S1. During inspection, the staff sends a start signal to the signal control module in the control system through the remote control to start the drive device;

[0016] S2. The control system controls the stepper motor to start, and the stepper motor drive shaft drives the drive sprocket to rotate; driven by the drive sprocket, the stainless steel chain begins to move back and forth along the reserved chain groove;

[0017] S3. As the stainless steel chain moves, the stainless steel silt removal rod device fixed on the chain moves synchronously; the brush on one side of the silt removal rod is in close contact with the surface of the rain grate during movement, and the brush cleans debris attached to the rain grate;

[0018] S4 before the end of the rainy weather, the staff conducts a secondary inspection, sends a shutdown signal to the signal control module in the control system via the remote control, and the drive device stops working;
