[0013] The technical effects of the above technical scheme are as follows: the pull belt is slidingly connected to the adapter column to realize stable guidance, so that the pull belt is not deviated or stuck when the piston moves up and down, at the same time, the clockwork mechanism is fixed to the inner wall of the first-stage expanded pipe to automatically store energy by using water flow pressure change; when the piston resets, the clockwork mechanism releases elastic potential energy through the pull belt to accurately control the reset speed and path of the piston, which significantly improves the dynamic response stability of the pressure assembly, prolongs the service life of the clockwork mechanism, and realizes closed-loop operation of energy recovery and self-maintenance through mechanical linkage.

[0015] The technical effects of the above technical scheme are as follows: the extension frame directly transmits the up-and-down movement of the piston to the filter screen, so that the filter screen dynamically rises and falls with the water flow pressure, and the upper and lower wall scraping rings on the outer side of the filter screen continuously scrape the inner wall of the inner pipe during the movement process to synchronously remove the attached impurities; when the piston rises, the wall scraping rings push the scraped impurities to the filter groove for temporary storage, so that the filter screen and cleaning are integrated, the risk of filter screen blockage is reduced, and there is no need to stop cleaning, thereby solving the problems of sudden decrease of drainage efficiency and high cost of manual intervention caused by impurity accumulation of traditional fixed filter screen.

[0023] The technical effects of the above technical scheme are that the elastic property of the spring enables the folding rod to periodically vibrate when subjected to water flow pressure. The vibration is transmitted to the fan blade through the folding rod, so that the fan blade angle can be automatically fine-tuned according to the change of water flow pressure. The automatic adjustment function ensures that the fan blade always maintains the optimal guide vane angle, optimizes the water flow path, and improves the water flow pressure boosting effect.

[0025] The technical effects of the above technical scheme are that the spiral vane and the containing ring can adapt to different water flow pressure changes. When the pressure is large, the rotation speed of the spiral vane increases, and the centrifugal field is stronger, further accelerating the water flow. When the water flow pressure is small, the spiral vane can still maintain a certain rotation speed, ensuring stable discharge of the water flow.
[0026] As preferred, the bottom end of the water inlet pipe is fixedly connected to a first-stage expansion pipe, the bottom end of the first-stage expansion pipe is fixedly connected to a second-stage expansion pipe, the bottom end of the second-stage expansion pipe is fixedly connected to a bottom water outlet pipe, and the mounting rod penetrates through the inner pipe and is fixedly connected to the bottom water outlet pipe.

[0028] Compared with the prior art, the advantages and positive effects of the present application are that:
[0029] 1. When water from the bridge enters through the inlet pipe, the water pressure pushes the piston downward, causing the extension frame and filter screen to descend, while the scraper ring simultaneously scrapes impurities from the inner wall of the inner pipe. When the piston returns to its original position, the spring mechanism pulls the filter screen upward via a belt, pushing the impurities into the filter tank for temporary storage. This design achieves self-cleaning of the pipe wall and centralized collection of impurities, reducing the frequency of manual cleaning and preventing filter screen clogging. It effectively solves the problems of reduced drainage efficiency and frequent manual maintenance caused by impurity accumulation in traditional fixed filters.
[0030] 2. The piston moves downward, driving the lead screw to rotate, which in turn causes the turntable and fan blades to swing. The combined action of the downstream water channel and the downward pressure resistance channel creates a vortex water flow, generating a pressurization effect at the bottom outlet pipe. This design enhances the impact force of the water flow, increases the drainage speed, and prevents backflow. It effectively solves the problems of traditional static pipes relying on gravity for drainage, which are prone to backflow and have low drainage efficiency.
[0031] 3. When the turntable rotates, the spiral blade drives the housing ring to revolve around the screw through the connecting rod, generating centrifugal force to accelerate the water flow a second time; the spring mechanism stores energy and releases energy when the water flow pressure weakens, pulling the piston to reset; this design achieves zero-energy water flow acceleration and self-maintenance cycle of the device, reducing energy consumption and operation and maintenance costs; it effectively solves the problems of traditional booster systems relying on external power, high energy consumption, and lack of autonomous energy recovery mechanism.
