[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes: a base 1, a water pump 2, a filter tank 3, a filter structure 4, and a sealing structure 5. The base 1 provides a stable support foundation for the entire device, ensuring that the components do not easily shake or shift during operation. The water pump 2 is installed on the upper surface of the base 1. The water pump 2 is the power core of the device, capable of drawing water from a lower position and transporting it to a designated location, thus realizing the function of water pumping and drainage. A filter tank 3 is located on one side of the water pump 2. The filter tank 3 is used to house the filter structure 4, providing a closed space for the water filtration process. The filter structure 4 is installed inside the filter tank 3. The function of the filter structure 4 is to filter the water entering the filter tank 3, removing impurities from the water. The filter structure 4 includes a guide pipe 6 and a filter element 7. The guide pipe 6 guides the flow of water. The filter element 7 is a key component of the filter system, designed to ensure water flows evenly through the filter tank 3. It intercepts solid impurities and purifies the water. The lower end of the guide pipe 6 is fixedly connected to the bottom of the filter tank 3, and the filter element 7 is fitted onto its outer surface. A sealing structure 5 is located at the top of the filter tank 3. This sealing structure 5 ensures the airtightness of the top of the filter tank 3, preventing water leakage and facilitating the opening of the filter tank 3 for maintenance or replacement of the internal filter element 7. The sealing structure 5 includes a sealing cover 8, a first connecting piece 9, a second connecting piece 10, a rotating block 11, a lead screw 12, and a rotating wheel 13. One side of the sealing cover 8 is hinged to the outer surface of the upper end of the filter tank 3, allowing it to rotate around the hinge point. The opening and closing of the sealing cover 8 serves a sealing function. A first connecting piece 9 is fixedly connected to the other side of the sealing cover 8. The first connecting piece 9 cooperates with the second connecting piece 10 to provide a connection point for fixing the sealing cover 8. The second connecting piece 10 is located below the first connecting piece 9 and is fixed to the filter tank 3. Working together with the first connecting piece 9, the sealing cover 8 is locked via components such as the screw rod 12. One end of the second connecting piece 10 is fixedly connected to the upper outer surface of the filter tank 3. Both the first connecting piece 9 and the second connecting piece 10 have movable grooves on their upper surfaces. These grooves provide space for the screw rod 12 to move, allowing it to pass through the two connecting pieces to fix the sealing cover 8. A rotating block 11 is rotatably connected to the inner wall of the movable groove of the second connecting piece 10. The rotating block 11 can rotate within the movable groove, providing support and a rotational basis for the lifting and lowering of the lead screw 12. The upper end of the rotating block 11 has a threaded hole that engages with the lead screw 12. Rotating the lead screw 12 allows it to move up and down. The lead screw 12 is threadedly connected inside the threaded hole at the upper end of the rotating block 11. When the lead screw 12 rotates within the threaded hole of the rotating block 11, it moves up and down, thereby driving the rotating wheel 13 to press or release the first connecting piece 9, thus locking and releasing the sealing cover 8. The upper end of the lead screw 12 is located inside the movable groove on the upper surface of the first connecting piece 9. The upper end of the lead screw 12 is fixedly connected to the rotating wheel 13, which allows the operator to easily rotate the lead screw 12. By rotating the rotating wheel 13, the lead screw 12 can be rotated, thereby adjusting its position.

[0017] In the specific implementation process, a handrail 14 is fixedly connected to the upper surface of one end of the base 1. The handrail 14 makes it easy for the operator to push or pull the device and facilitates the movement of the device. Four locking casters 15 are installed on the lower surface of the base 1. The locking casters 15 enable the device to move flexibly and make it easy to adjust the position of the device. The locking function can fix the device after it reaches the designated position to prevent the device from moving on its own.

[0018] The water pump 2 is equipped with a drain pipe 16 at its outlet. The drain pipe 16 is used to transport the filtered water pumped by the water pump 2 to a designated drainage location. The water pump 2 is equipped with a connecting pipe 17 at its inlet. The connecting pipe 17 connects the water pump 2 to the filter tank 3, allowing the filtered water to enter the water pump 2. The water pump 2 is electrically connected to an external power source when in use. The external power source provides power to the water pump 2 to ensure that the water pump 2 can work normally.

[0019] The filter tank 3 has an inlet on its upper outer surface, which is the channel for water to enter the filter tank 3. An inlet pipe 18 is fixedly connected to the inner wall of the inlet on the upper outer surface of the filter tank 3. The inlet pipe 18 is used to introduce external water into the filter tank 3 and is the water delivery pipe for the filtration system. The inlet pipe 18 is placed in the water when in use. The filter tank 3 has a through hole on its lower outer surface, which provides an interface for the connection between the connecting pipe 17 and the filter tank 3, so that the filtered water can flow from the filter tank 3 into the connecting pipe 17. The end of the connecting pipe 17 away from the water pump 2 is fixedly connected to the inner wall of the through hole on the lower outer surface of the filter tank 3. The end of the connecting pipe 17 away from the water pump 2 extends into the interior of the filter tank 3. The connecting pipe 17 extending into the interior of the filter tank 3 facilitates the intake of the filtered water in the filter tank 3 into the water pump 2.

[0020] The outer surface of the guide pipe 6 is provided with dispersion holes, which allow water to be evenly dispersed through the filter element 7 and enter the guide pipe 6, so that the water flow can fully contact the filter element 7 and improve the filtration effect. The lower end of the guide pipe 6 is fixedly connected to the connecting pipe 17 located at one end inside the filter tank 3. The guide pipe 6 and the connecting pipe 17 are interconnected, which ensures that the filtered water can enter the connecting pipe 17 through the guide pipe 6 and then be pumped out by the water pump 2.

[0021] Among them, a rocker arm 19 is fixedly connected to the upper surface of the rotating wheel 13. The rocker arm 19 further facilitates the operator to rotate the rotating wheel 13, saves effort, and makes the operation more convenient. A rubber pad 20 is fixedly connected to the lower surface of the rotating wheel 13. The rubber pad 20 can increase the friction between the rotating wheel 13 and the first connecting piece 9, so that the rotating wheel 13 has a better pressing effect on the first connecting piece 9, while avoiding direct contact between the rotating wheel 13 and the first connecting piece 9 to prevent wear. The rubber pad 20 is attached to the upper surface of the first connecting piece 9.

[0022] The working principle of this utility model is as follows: First, the device is moved to the designated emergency drainage position by the handle 14 at one end of the base 1 and the four locking casters 15 on the lower surface. The locking function of the casters 15 is used to fix the device. The base 1 provides stable support for the entire device. Then, the water inlet pipe 18 at the water inlet on the upper outer surface of the filter tank 3 is placed into the water to be pumped. After the water pump 2 is electrically connected to an external power source to obtain power, it starts. The water pump 2, as the power core, begins to work. Its water inlet is connected to the water inlet... Connector 17 is connected to the through hole on the lower outer surface of filter tank 3, and the end of connector 17 away from water pump 2 extends into the interior of filter tank 3 and is fixedly connected to the lower end of guide pipe 6 and interconnected. Under the suction of water pump 2, external water enters filter tank 3 through inlet 18 and inlet at the upper end of filter tank 3. The water entering filter tank 3 flows through filter element 7, which is sleeved on the outer surface of guide pipe 6. Filter element 7 intercepts solid impurities in the water to purify the water quality, while the dispersion holes allow the water to be evenly dispersed through the filter. The filter element 7 enters the guide pipe 6 to improve the filtration effect. The filtered water enters the connecting pipe 17 through the guide pipe 6, and is then transported to the water pump 2 through the connecting pipe 17. The water pump 2 transports the filtered water to the designated drainage point through the drain pipe 16 at the outlet. During the entire pumping and drainage process, the sealing structure 5 at the upper end of the filter tank 3 ensures the airtightness of the filter tank 3. The sealing cover 8 closes the upper end of the filter tank 3 around the hinge point. The rocker arm 19 on the upper surface of the rotating wheel 13 drives the rotating wheel 13 to rotate, and the rotating wheel 13 drives the lead screw. 12 rotates in the threaded hole of the rotating block 11 in the movable groove of the second connecting piece 10, and the lead screw 12 moves up and down accordingly, so that the rubber pad 20 on the lower surface of the rotating wheel 13 is tightly attached to the upper surface of the first connecting piece 9. The cooperation between the first connecting piece 9 and the second connecting piece 10 locks the sealing cover 8 to prevent water from leaking from the upper end of the filter tank 3. When maintenance or replacement of the filter element 7 is required, the rocker arm 19 is rotated in the opposite direction, so that the lead screw 12 drives the rotating wheel 13 to move upward, loosening the pressure on the first connecting piece 9, and the sealing cover 8 can be opened for operation.
