However, there are many fallen leaves and branches in the garden, which gather at the drain outlet and are difficult to fall, causing drainage blockage. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a water supply and drainage device for municipal landscaping to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A water supply and drainage device for municipal landscaping, comprising a tread block and a drainage pipe, wherein a guide mechanism is fixedly connected between the tread block and the drainage pipe; The guiding mechanism comprises: A limit assembly is fixedly connected between the tread block and the drain pipe. A tread block and a guide mechanism connected to the drain pipe are arranged at the step position. The gravity generated by people stepping on the tread block is used to drive the shielding plate to squeeze the fallen leaves and branches on the top of the drain pipe, so that they fall into the drain pipe for discharge, effectively avoiding the drainage blockage problem caused by the gathering of fallen leaves and branches at the drain outlet in the garden, and ensuring the smoothness of drainage; The shielding plate is fixedly connected to the bottom of the treading block, and the treading block is inserted into the limiting hole of the drain pipe through the limiting rod. The first spring itself is elastic. After a person steps on the treading block, the first spring drives the treading block to rise. The shielding plate is arranged at the bottom of the treading block through the connecting rod. Then, the shielding plate is squeezed to the top of the drain pipe by the gravity generated by the person's stepping. Then, the shielding plate squeezes the fallen leaves and branches on the top of the drain pipe and drops them into the drain pipe for discharge; A sealing component is fixedly connected to the outer wall of the shielding plate.

[0005] Preferably, a connecting rod is fixedly connected between the top of the shielding plate and the bottom of the pedal block, and the sealing ring and the second spring in the sealing assembly are designed so that when the shielding plate is attached to the top of the drain pipe, the elastic action of the second spring can squeeze the gas in the upper half of the sealing ring to the lower half, thereby increasing the air tightness between the shielding plate and the top of the drain pipe, effectively preventing gas leakage, and ensuring the effect of the air compressor mechanism using negative pressure to suck fallen leaves and branches.

[0006] Preferably, the limit assembly includes a first spring, which is fixedly connected between the drain pipe and the pedal block. A limit hole is provided at the top of the drain pipe, and a limit rod is inserted into the inner wall of the limit hole. The top of the limit rod is fixedly connected to the bottom of the pedal block. The arrangement of the air compressor mechanism further enhances the device's ability to clean the drain pipe. During the descending process of the pedal block, the pressing rod squeezes the pressure button, and the control device starts the fan and the telescopic machine. The fan sucks the gas in the drain pipe, and the telescopic machine drives the extrusion plate to move, thereby increasing the sealing space and using negative pressure to suck fallen leaves and branches on the drain pipe into the drain pipe, greatly enhancing the effect of cleaning debris at the drain outlet.

[0007] Preferably, the sealing assembly comprises a sealing ring, the sealing ring is fixedly connected to the outer ring of the shielding plate, and a second spring is fixedly connected between the sealing ring and the outer wall of the shielding plate.

[0008] Preferably, a bracket is fixedly connected between the second spring and the shielding plate.

[0009] Preferably, an air compressor mechanism is fixedly connected to the outer wall of the pedal block, and the pressure button is electrically connected to the control device, so that the start-up and operation of multiple devices such as the fan and the telescopic machine can be automatically controlled by the simple action of a person stepping on the pedal block. The degree of automation is high, and there is no need for manual cleaning of debris at the drain outlet, which saves labor costs and also improves the working efficiency and stability of the drainage system.

[0010] Preferably, the air compression mechanism includes a pressing rod, which is fixedly connected to the outer wall of the pedal block, a pressure button is fixedly connected to the top of the drain pipe relative to the pressing rod, a control device is fixedly connected to the outer wall of the drain pipe, a fan is fixedly connected to the outer wall of the control device, the bottom of the fan is plugged into the outer wall of the drain pipe, and an extrusion assembly is fixedly connected to the inner wall of the drain pipe.

[0011] Preferably, the pressing rod is in active contact with the pressed button.

[0012] Preferably, the extrusion assembly includes a telescopic machine, which is fixedly connected to the inner left side of the drain pipe. When the shielding plate is attached to the top position of the drain pipe, the control device controls the fan to start, and the fan sucks the gas in the drain pipe. The telescopic machine is powered on and starts to drive the extrusion plate to move in the drain pipe. The vertical plate squeezes the extrusion plate through the intercepting rod and the connecting plate, and then squeezes the inner wall of the drain pipe. At this time, when the extrusion plate moves toward the right side in the drain pipe, the shielding plate and the extrusion plate seal part of the space in the drain pipe, so the movement of the extrusion plate will increase the size of the sealed space, and then cooperate with the fan to suck the gas in the drain pipe. During the suction process In the process, as the gas in the sealed space is continuously extracted, the internal pressure continues to decrease, the pressure difference with the outside world gradually increases, and the suction force will gradually increase. Under the elasticity of the first spring, the pedal block rises. At this time, the shielding plate is away from the top of the drain pipe. At this time, the leakage at the top of the drain pipe will use the negative pressure in the drain pipe to suck the fallen leaves and branches on the drain pipe. The outer wall of the telescopic machine is movably connected with a vertical plate, the bottom of the vertical plate is rotatably connected with a connecting plate, the outer wall of the connecting plate is fixedly connected with an extrusion plate, the top of the vertical plate is fixedly connected with a third spring between the extrusion plate, and the outer wall of the vertical plate is fixedly connected with an intercepting rod.

[0013] Preferably, the vertical plate is rotatably connected to the connecting plate via a bearing. When the telescopic machine drives the extrusion plate to reset, the vertical plate is connected through the bearing, the connecting plate and the extrusion plate. Therefore, during the resetting process, the bottom position of the extrusion plate will be pulled by the connecting plate, thereby causing the extrusion plate to tilt. At this time, the fallen leaves and branches in the drain pipe pass between the extrusion plate and the inner wall of the drain pipe, and the intercepting rod is in active contact with the extrusion plate.

[0014] The present invention provides a water supply and drainage device for municipal landscaping. It has the following beneficial effects: 1. The water supply and drainage device for municipal landscaping is equipped with a tread block and a guide mechanism connected to the drain pipe at the step position. The gravity generated by people stepping on the tread block drives the shielding plate to squeeze the fallen leaves and branches on the top of the drain pipe, causing them to drop into the drain pipe for discharge. This effectively avoids the drainage blockage problem caused by the gathering of fallen leaves and branches at the drain outlet in landscaping, and ensures smooth drainage.

[0015] 2. The water supply and drainage device for municipal landscaping has further improved its ability to clean the drainage pipes by setting up an air compressor mechanism. When the pedal block descends, the pressure rod squeezes the pressure button, and the control device starts the fan and telescopic machine. The fan sucks the gas in the drainage pipe. At the same time, the telescopic machine drives the extrusion plate to move, increasing the sealing space, and using negative pressure to suck the fallen leaves and branches on the drainage pipe into the drainage pipe, greatly enhancing the effect of cleaning the debris at the drain outlet.

[0016] 3. The water supply and drainage device for municipal landscaping uses the sealing ring and the second spring design in the sealing assembly, so that when the shielding plate is attached to the top of the drain pipe, the elastic action of the second spring can squeeze the gas in the upper half of the sealing ring to the lower half, thereby increasing the air tightness between the shielding plate and the top of the drain pipe, effectively preventing gas leakage, and ensuring the air compressor mechanism uses negative pressure to suck fallen leaves and branches.

[0017] 4. The water supply and drainage device for municipal landscaping, through the electrical connection between the pressure button and the control device, realizes the automatic control of the start-up and operation of multiple devices such as fans and telescopic machines with the simple action of people stepping on the pedal block. It has a high degree of automation and does not require manual cleaning of debris in the drain outlet, saving labor costs and improving the working efficiency and stability of the drainage system.
