Description

Technical Field

[0001] The present invention relates to a pool device, and more specifically, to a pool pumping and drainage system. Background Technology

[0002] Currently, the pool water filtration system installed on the pool includes a skimmer and a filter device. The skimmer is installed at the top of the pool near the water surface. The inlet of the filter device is connected to the skimmer, and the outlet of the filter device is connected to the pool via a pipe. Activating the filter device circulates and filters the pool water. This type of pool water filtration system only has a filtration function and cannot pump water from the pool. When the pool needs to be drained, other water pumps are required, which not only increases the initial investment in equipment but also the workload of installation. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a water tank pumping and drainage system that can not only filter the water in the tank, but also pump and drain the water, eliminating the need for investment in and installation of a dedicated water pump.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a water tank pumping and drainage system, including a water channel connected to the water tank and a filtration device; Water passage, connecting the pool and the filtration device, is used for guiding the flow of pool water during filtration and drainage processes; The filtration device includes a water pump for drawing water from a pool, enabling the water to be drawn, filtered, and circulated, or for the water to be drawn and discharged directly to the outside, and for the pool to be drained.

[0005] The filtration system uses its built-in pump to draw water from the pool, selecting different operating modes as needed to filter and circulate the pool water. The filtered water then flows back into the pool. Alternatively, it can drain the pool water directly from the filtration system, effectively emptying the pool completely. Water channels guide the flow, facilitating drainage. This system not only filters the pool water but also drains it, eliminating the need for a dedicated water pump and the associated installation work.

[0006] Preferably, the water channel is equipped with a water inlet pipe, and the lower end of the water inlet pipe has a water inlet hole, which is located near the bottom of the pool. The water inlet hole being close to the bottom of the pool ensures that the water in the pool can be drained.

[0007] Preferably, the water inlet pipe includes a fixed section and a movable section, which are fitted together with the fixed section. The movable section is designed to be raised and lowered, and the lower end of the movable section extends downward beyond the lower end of the fixed section. The water inlet hole is located at the lower end of the movable section.

[0008] The length of the inlet pipe is adjustable, making it versatile and ensuring that the lower end of the inlet pipe can be close to the bottom of the pool.

[0009] Preferably, a differential pressure pipe is installed on the inlet pipe, with its inner end connected to the inlet pipe and its outer end connected to the water tank. A piston is installed inside the differential pressure pipe, and the piston is rotatably connected to a piston rod. A pre-tightening spring is connected between the inner end of the differential pressure pipe and the piston. The piston rod is provided with a guide groove, which includes a straight section and a spiral section. A guide post is connected to the differential pressure pipe, and the end of the guide post is movably inserted into the guide groove. A movable push rod and a push-pull rod are connected to the lower end of the inlet pipe. A scraper for cleaning the lower end face of the inlet pipe is connected to the push rod. A return spring is connected between the push rod and the inlet pipe. Several auxiliary through holes are provided on the side wall of the inlet pipe near the lower end. A baffle plate for covering the auxiliary through holes is connected to the inlet pipe. The baffle plate is movable, and a hinged connecting rod is connected between the baffle plate and the push-pull rod. A push plate is connected to the push rod, and a top rod and a top plate are connected to the push-pull rod. A one-way push post is connected to the piston rod. The one-way push post is used to push the push plate and the top plate. The top rod abuts against the end of the piston rod, and the push plate and the top plate are staggered. When the filter starts pumping water, the pressure in the inlet pipe decreases, the piston moves inward, and the one-way push column abuts against the push plate, driving the push rod to move. This causes the scraper to scrape and clean the end face of the inlet pipe. When the spiral section of the guide groove on the piston rod slides past the guide column, the piston rod rotates, causing the one-way push column to separate from the push plate. Under the action of the return spring, the push rod returns to its original position, and the scraper cleans the end face of the inlet pipe again. When the inlet hole becomes blocked, the pressure in the inlet pipe decreases further, the piston moves further inward, and the one-way push column on the piston rod abuts against the top plate, driving the push-pull rod to move. The push-pull rod pushes the baffle plate upward through the connecting rod, opening the auxiliary through hole to allow water to enter the inlet pipe and prevent blockage. Afterward, the water pressure in the inlet pipe decreases, the piston moves outward, and at this time, the one-way push column flips upward as it slides past the top plate without moving the push-pull rod. When the inlet pipe stops pumping water, the water pressure in the inlet pipe and the pool is equal. The piston moves outward to return to its original position, and the one-way push rod flips upward as it slides past the push plate without moving the push rod. The end of the piston rod abuts against the top rod, driving the push-pull rod to move back to its original position, causing the baffle plate to return to cover the auxiliary through hole. This structural design prevents blockage at the lower end of the inlet pipe.

[0010] Preferably, the scraper is equipped with a brush. The brush can improve the cleaning effect of the scraper on the end of the water inlet pipe.

[0011] Preferably, a skimmer is installed on the water tank, and a floating water tank is installed at the corresponding position of the skimmer on the water tank. Vertically arranged chutes are provided on the water tank and the floating water tank, and sliding seats are installed on the chutes. The skimmer is installed on the sliding seats, and a float is installed on the skimmer. The skimmer is connected to the water channel through a pipe.

[0012] The float provides buoyancy to the skimmer, ensuring that it always floats on the water surface. As the skimmer floats up and down, the slide block slides up and down in the chute. This structural design allows the skimmer to adapt to the water depth in the pool, making it highly versatile.

[0013] Preferably, the filter device outlet is connected to a water outlet pipe, the end of which is detachably connected to the water tank, and the filter device inlet is connected to the water channel. The detachable connection between the water outlet pipe and the water tank facilitates adjustment of the water outlet mode. The connection between the water outlet pipe and the water tank enables water circulation, and the removal of the water outlet pipe from the water tank enables pumping and drainage.

[0014] As a preferred option, a reversing joint is installed on the water channel. The reversing joint is equipped with a filter interface, a pumping interface, and an outlet interface. The filter interface and the pumping interface are both connected to the water tank, and the outlet interface is connected to the filter device. The reversing joint switches the flow channels to achieve the connection between the filter interface and the outlet interface, or between the pumping interface and the outlet interface, or between the filter interface, the pumping interface, and the outlet interface.

[0015] Different functions are achieved by switching the flow channels using a reversing connector. When switched to the position where the filter interface and the outlet interface are connected, the pump interface is closed, and the filter device is connected to the filter interface. Activating the filter device allows water from the top of the pool to enter the filter interface, be filtered by the filter device, and then flow back into the pool for recycling, thus achieving the pool water filtration function. When switched to the position where the filter interface, pump interface, and outlet interface are connected, water from the pool flows through the filter interface and pump interface into the filter device, is filtered by the filter device, and then flows back into the pool for recycling, again achieving the pool water filtration function.

[0016] When the pumping and outlet ports are connected, the filter port is closed, and the filter device is connected to the pumping port. Activating the filter device draws water from the pool into it, and after passing through the filter, it is discharged directly outwards, thus achieving the pool's pumping and draining functions.

[0017] The reversing joint enables the switching of flow paths in the water channel, thereby achieving different functions.

[0018] Preferably, the reversing joint has a connecting cavity, and the filter interface, water pumping interface, and water outlet interface all extend through the inner wall of the connecting cavity. A valve plate is installed in the connecting cavity, and the valve plate is connected to a switching knob. The switching knob is installed on the reversing joint, and the valve plate is sealed and fitted to the inner wall of the connecting cavity. Rotating the switching knob causes the valve plate to cover the filter interface, water pumping interface, and water outlet interface.

[0019] The switching knob rotates to close the valve plate to different interfaces, thereby switching the flow path. It has a simple structure and is easy to operate.

[0020] As a preferred option, a water inlet is installed on the water tank, and a connecting pipe is provided at the corresponding position of the water pumping interface on the reversing connector, and the connecting pipe is connected to the water inlet.

[0021] The connecting pipe on the reversing joint connects to the water inlet on the water tank, making the connection convenient and reliable.

[0022] Compared with the prior art, the beneficial effects of the present invention are: (1) The pool can not only filter the pool water, but also pump and drain the pool water, saving the investment in equipment and the workload of equipment installation for setting up a water pump; (2) The water inlet pipe will not be blocked; (3) The skimmer is set in a floating manner, which ensures reliable skimming and water discharge.

[0031] The filtration system uses its built-in pump to draw water from the pool, allowing for filtration and circulation of the pool water in different operating modes as needed. The filtered water then flows back into the pool. Alternatively, the system can drain the pool water directly from the filtration system, effectively emptying the pool completely. Water channels guide the water flow, facilitating drainage. This type of pool with built-in drainage not only filters the water but also drains it, eliminating the need for a dedicated water pump and the associated installation work.

A return spring 40 connects the push rod and the water inlet pipe. Several auxiliary through holes 41 are provided on the side wall of the water inlet pipe near the lower end. A baffle plate 42 for covering the auxiliary through holes is connected to the water inlet pipe. The baffle plate is movable, and a connecting rod 43 is hinged between the baffle plate and the push-pull rod, with the connecting rod inclined. A push plate 44 is connected to the push rod, and a top rod 45 and a top plate 46 are connected to the push-pull rod. A one-way push post 47 is connected to the piston rod. The one-way push post pushes the push plate and the top plate, and the top rod abuts against the end of the piston rod. The push plate and the top plate are staggered. A positioning cover 48 is connected to the inner end of the differential pressure pipe. The positioning cover is annular, and a pre-tightening spring abuts against the positioning cover. A limiting pin 49 is connected to the differential pressure pipe, and the piston abuts against the limiting pin. A clearance groove 50 is provided on the outer side of the piston on the differential pressure pipe, through which the push plate, top plate, and push rod all pass. The push plate is positioned between the top plate and the push rod, and the push plate and top plate are circumferentially offset. A one-way push column is hinged to the piston rod, and a positioning torsion spring is installed between the piston rod and the one-way push column. A positioning block 51 is provided on the piston rod, positioned on the outer side of the one-way push column, and the one-way push column abuts against the positioning block. A push rod is positioned on the outer surface of the lower end of the inlet pipe, and a push-pull rod is positioned on the inner surface of the lower end of the inlet pipe.

Other structures are the same as in Embodiment 1.

[0034] When the filter starts pumping water, the pressure in the inlet pipe decreases, the piston moves inward, and the one-way push column abuts against the push plate, driving the push rod to move. This causes the scraper to scrape and clean the end face of the inlet pipe. When the spiral section of the guide groove on the piston rod slides past the guide column, the piston rod rotates, causing the one-way push column to separate from the push plate. Under the action of the return spring, the push rod returns to its original position, and the scraper cleans the end face of the inlet pipe again. When the inlet hole becomes blocked, the pressure in the inlet pipe decreases further, the piston moves further inward, and the one-way push column on the piston rod abuts against the top plate, driving the push-pull rod to move. The push-pull rod pushes the baffle plate upward through the connecting rod, opening the auxiliary through hole to allow water to enter the inlet pipe and prevent blockage. Afterward, the water pressure in the inlet pipe decreases, the piston moves outward, and at this time, the one-way push column flips upward as it slides past the top plate without moving the push-pull rod. When the inlet pipe stops pumping water, the water pressure in the inlet pipe and the water tank are the same. The piston moves outward to return to its original position. When the one-way push column slides past the push plate, it flips upward without driving the push rod to move. The end of the piston rod abuts against the top rod, driving the push-pull rod to move back to its original position, so that the baffle plate returns to its original position and covers the auxiliary through hole.

[0035] The float provides buoyancy to the skimmer, ensuring that it always floats on the water surface. As the skimmer floats up and down, the slide block slides up and down in the chute. This structural design allows the skimmer to adapt to the water depth in the pool, making it highly versatile.
