When it is necessary to filter the cleaned impurities, the filter screen 603 can be installed inside the drain pipe 3 when using the device. First, pull the pull rod 611, and the pull rod 611 moves to drive the T-plate 608 to move. The movement of the T-plate 608 drives the hinged plate 607 to move. The hinged plate 607 moves and pulls the two sliding plates 605 to move toward each other on the surface of the U-shaped rod 604. The two sliding plates 605 move toward each other on the surface of the U-shaped rod 604, squeezing the second spring 606 so that the second spring 606 is compressed. At the same time, the movement of the T-plate 608 also drives the positioning rod 609 to move. When the positioning rod 609 is removed from the inside of the mounting groove 601, the mounting plate 602 is placed into the mounting groove. When the mounting plate 602 is located inside the mounting groove 601, the filter screen 603 will be located inside the drain pipe 3. Then the pull rod 611 is loosened and the rebound force of the second spring 606 is used to reset the positioning rod 609. The positioning rod 609 is reset and then inserted into the positioning hole 610. The positioning rod 609 and the positioning hole 610 are plugged into each other, thereby limiting the mounting plate 602 inside the mounting groove 601. The mounting plate 602 is limited inside the mounting groove 601, thereby completing the installation of the filter screen 603. Through the cooperation of the above structure, the purpose of installing the filter screen 603 is achieved, so that the filter screen 603 is used to filter the cleaned impurities to ensure that the water source flowing into the next link is clean.

[0031] Specifically, a U-shaped rod 604 is fixedly installed on the outer wall surface of the drain pipe 3, and two sliding plates 605 are slidably connected to the surface of the U-shaped rod 604.

A hinged plate 607 is hinged on the surface of the sliding plate 605, and a T-shaped plate 608 is hinged on the end of the hinged plate 607 away from the sliding plate 605.

[0032] In this embodiment, the second spring 606 is provided to limit the position of the sliding plate 605 on the surface of the U-shaped rod 604 .

[0033] Specifically, a pull rod 611 is fixedly mounted on the surface of the T-shaped plate 608 , a positioning rod 609 is fixedly mounted on the surface of one end of the T-shaped plate 608 away from the pull rod 611 , and a positioning hole 610 is opened on one side surface of the mounting plate 602 .

[0034] In this embodiment, the positioning rod 609 and the positioning hole 610 are provided to limit the mounting plate 602 inside the mounting groove 601 .

[0035] Working principle: By setting up the cleaning device 5, when the device needs to be used, first use the flange 2 to connect the thermal pipe 1 and the drain pipe 3, and then the outside water will flow into the thermal pipe 1. When it is necessary to drain the water, open the valve 4. At this time, the water inside the thermal pipe 1 will be transported into the drain pipe 3. The support rod 56 rotates, and the rotation of the support rod 56 drives the cleaning plate 57 to rotate. When the cleaning plate 57 rotates, it cleans the inside of the drain pipe 3. At the same time, the rebound force of the first spring 55 can make the cleaning plate 57 and the inner wall of the drain pipe 3 fit together, which can improve the cleaning effect of the cleaning plate 57 on the inside of the drain pipe 3. Through the cooperation of the above structure, the difficulty of cleaning the inside of the drain pipe 3 is reduced, thereby ensuring the cleanliness of the inside of the drain pipe 3, and further preventing dirt from accumulating inside the drain pipe 3, which causes the thickness of the drain pipe 3 to increase, resulting in a decrease in its drainage volume, further affecting its drainage. When it is necessary to filter the cleaned impurities, the filter screen 603 can be installed inside the drain pipe 3 when using the device. First, pull the pull rod 611, and the pull rod 611 moves to drive the T-plate 608 to move. The movement of the T-plate 608 drives the hinged plate 607 to move. The hinged plate 607 moves and pulls the two sliding plates 605 to move toward each other on the surface of the U-shaped rod 604. The two sliding plates 605 move toward each other on the surface of the U-shaped rod 604, squeezing the second spring 606 so that the second spring 606 is compressed. At the same time, the movement of the T-plate 608 also drives the positioning rod 609 to move. When the positioning rod 609 is removed from the inside of the mounting groove 601, the mounting plate 602 is placed into the mounting groove. When the mounting plate 602 is located inside the mounting groove 601, the filter screen 603 will be located inside the drain pipe 3. Then the pull rod 611 is loosened and the rebound force of the second spring 606 is used to reset the positioning rod 609. The positioning rod 609 is reset and then inserted into the positioning hole 610. The positioning rod 609 and the positioning hole 610 are plugged into each other, thereby limiting the mounting plate 602 inside the mounting groove 601. The mounting plate 602 is limited inside the mounting groove 601, thereby completing the installation of the filter screen 603. Through the cooperation of the above structure, the purpose of installing the filter screen 603 is achieved, so that the filter screen 603 is used to filter the cleaned impurities to ensure that the water source flowing into the next link is clean.
