Description

Technical Field

[0001] The present invention relates to the technical field of rainwater treatment, and in particular to an unpowered rainwater treatment device and a rainwater treatment method. Background Art

[0002] With the development of rainwater treatment technology, rainwater treatment devices have emerged. The rainwater treatment devices can effectively filter impurities or foreign objects entrained in rainwater and discharge rainwater to prevent waterlogging caused by debris in rainwater blocking rainwater discharge. In traditional technologies, for example, the invention patent with announcement number: CN108503106A discloses a non-powered rural sewage treatment device. The non-powered rural sewage treatment device includes a sewage treatment device, a machine body, a water outlet pipe, a support leg, a control cabinet, a water inlet pipe, a control panel, a top cover, and a bottom of the top cover. It is fixedly connected to the top of the machine body, the back of the control cabinet is vertically connected to the front side of the machine body, the side of the control panel is embedded in the front side of the control cabinet, the left end of the water inlet pipe is connected to the inside of the machine body, the bottom of the machine body is vertically connected to the top of the water outlet pipe, the sewage treatment device is installed inside the machine body, and the supporting feet are connected in sequence to form a triangular structure and arranged on the machine body. The sewage treatment device consists of a water inlet device, a filtering device, a linkage device, a circulating extrusion device, an adjusting device, a manual device, and an oxygen supply device. The device can quickly separate solids and liquids from sewage. The water inlet device consists of a water pressure conversion chamber, an impeller, The impeller is composed of a transmission belt, a gear, a gear plate, a second transmission belt, a positioning wheel, a fixing frame, and an adjusting bolt. The impeller is installed in the water pressure conversion chamber. The front end side of the impeller is connected to the rear end side of the gear through a transmission belt. When in use, water is passed into the water pressure conversion chamber, and the impeller is driven to rotate by the impact force generated during the water flow, thereby providing power for the sewage treatment device. However, the unpowered rural sewage treatment device uses the impact force of water to drive the impeller to rotate continuously. In the case of insufficient rainwater, it is difficult to drive the impeller to rotate, resulting in the impeller being unable to provide power for the sewage treatment device, making it difficult for the sewage treatment device to achieve sewage treatment work. That is, the sewage treatment device needs to rely on the impact force of rainwater to provide an initial power source for the impeller. When the impact force of rainwater is small, the impeller is difficult to start, which makes it difficult for the sewage treatment device to achieve sewage treatment work. When the unpowered mechanism uses the impact force of rainwater as the initial power source, a specific impact force of rainwater is required, thereby limiting the application scenario of the unpowered mechanism, and limiting the application scope of the unpowered sewage treatment device. Summary of the invention

[0003] Based on this, it is necessary to provide an unpowered rainwater treatment device to address the technical problem that when the unpowered mechanism of the current rainwater treatment device uses the impact force of rainwater as the initial power source, a specific impact force of rainwater is required, thereby limiting the application scenarios of the unpowered mechanism and limiting the application scope of the unpowered sewage treatment device.

[0057] The use method of the non-powered rainwater treatment device 100 of the present invention is as follows: when the water storage tank 33 receives rainwater, the water storage tank 33 obtains the gravity of the rainwater, so that the water storage tank 33 descends along the first guide component 34 under the influence of gravity, and drives the driven wheel 314 to rotate along the first direction through the transmission chain 32, and the one-way groove 317 of the driven wheel 314 abuts against the swing claw 315 of the one-way claw 313 through the blocking surface 319, so that the swing claw 315 drives the driven wheel 312 to rotate, and the rotating driven wheel 312 drives the support roller 21 to rotate, so that the filter belt 22 on the support roller 21 is displaced, and then the debris cleaning mechanism 50 cleans the displaced filter belt 22, after the water discharge mechanism 40 discharges water, the water reservoir 33 loses weight, and the counterweight block 35 pulls the water reservoir 33 to rise along the first guide assembly 34 through the transmission chain 32, so that the transmission chain 32 drives the driven wheel 314 to rotate along the second direction, and the one-way groove 317 of the driven wheel 314 guides the swing claw 315 to disengage from the one-way groove 317 through the inclined surface 318, thereby preventing the driven wheel 312 from rotating relative to the driven wheel 314. Therefore, the driven wheel 312 is stationary relative to the driven wheel 314, and the support roller 21 and the filter belt 22 stop moving, thereby preventing the filter belt 22 from moving in the opposite direction, so that the debris can effectively enter the debris cleaning mechanism 50.

[0058] A rainwater treatment method of an unpowered rainwater treatment device 100 comprises the following steps:

[0059] Step S01: using a mold shell 10 to receive rainwater, and controlling the rainwater to flow through the filtering mechanism 20 into the transmission mechanism 30;

[0060] Step S02: The transmission mechanism 30 receives and stores rainwater flowing through the filter mechanism 20. Under the influence of the gravity of the rainwater, the transmission mechanism 30 is displaced. The filter mechanism 20 is actuated according to the potential energy generated by the transmission mechanism 30 during displacement. A debris cleaning mechanism 50 is used to clean impurities on the filter mechanism 20 during the actuation process.
