DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 3 An energy-saving box-type intelligent non-negative pressure water supply device comprises a water tank 2 and a mounting frame 1. The water tank 2 has no negative pressure. The water in the water tank 2 can be discharged to a desired place. The device has good intelligence when in use. A booster water pump is installed on the mounting frame 1. The booster water pump is connected to the water tank 2 through a delivery pipe 3. A filter screen 14 is fixedly connected to the delivery pipe 3. A shell 7 is fixedly arranged above the delivery pipe 3. A partition 11 is fixedly connected to the shell 7. The partition 11 has good sealing performance when connected to the inner wall of the shell 7, and the inside of the shell 7 is divided into two spaces. A fixed pipe 10 is fixedly connected to the shell 7, and a pipe is threadedly connected to the fixed pipe 10. A sealing plate 5 and a sliding rod 6 are slidably connected to the shell body 7, a scraper bar 13 with an L-shaped cross section is fixedly connected to the lower end of the sliding rod 6, and two rectangular openings that penetrate the conveying pipe 3 are provided at the bottom of the shell body 7. In the initial state, the sealing performance of the scraper bar 13 and the sealing plate 5 when connected is good, which can effectively prevent the water in the conveying pipe 3 from entering the inside of the shell body 7. A slag discharge port is provided on the conveying pipe 3, and a cover plate 16 with a T-shaped cross section is clamped in the slag discharge port. Two clamping blocks 21 are slidably connected to the top of the shell body 7, and the two clamping blocks 21 are clamped with the sliding rod 6 and the sealing plate 5 respectively. A rotating component is provided on one side of the conveying pipe 3.

[0023] The rotating assembly includes a fixed sleeve 17 and a screw rod 18. The fixed sleeve 17 is fixedly connected to the side of the conveying pipe 3. The screw rod 18 is rotatably connected to the fixed sleeve 17. A slider 19 is threadedly connected to the screw rod 18. Two fixed rods 4 are fixedly connected to the slider 19. Two openings for moving the fixed rod 4 are provided on the fixed sleeve 17. A mounting rod 8 with an L-shaped cross section is fixedly connected to one side of the cover plate 16. A card slot is provided on one side of the mounting rod 8. One of the fixed rods 4 is carded with the card slot. One end of one of the fixed rods 4 is hinged with two hinged rods 12. The two hinged rods 12 are respectively hinged with two blocks 21. During the relative rotation of the screw rod 18 and the fixed sleeve 17, the slider 19 moves along the screw rod 18 at the same time. The opening can limit the moving trajectory of the two fixed rods 4. The cross section of one fixed rod 4 is rectangular, and the cross section of the other fixed rod 4 is L-shaped. When the fixed rod 4 is carded with the card slot, the cover plate 16 and the slag discharge port can be effectively prevented from being separated. The cover plate 16 has good sealing performance when in contact with the inner wall of the slag discharge port.

[0024] A limit frame 20 having a U-shaped cross section is fixedly connected to the upper surface of the conveying pipe 3, and each block 21 is slidably connected to the limit frame 20. The sealing plate 5 and the sliding rod 6 are provided with grooves for engaging with the corresponding block 21. The limit frame 20 can limit the movement trajectory of the two blocks 21.

[0025] The cross section of the sealing plate 5 is L-shaped, and an inclined surface is provided on the sealing plate 5. A limiting strip 9 is fixedly connected to one side of the sealing plate 5. When water flows through the rectangular opening into the interior of the delivery pipe 3, the water can slide along the inclined surface of the L-shaped sealing plate 5, effectively preventing the water from accumulating on the surface of the sealing plate 5. The limiting strip 9 can effectively prevent the sealing plate 5 from detaching from the rectangular opening. A guide block 15 with a right-angled trapezoidal cross section is fixedly connected to the lower inner wall of the delivery pipe 3. One side surface of the guide block 15 fits the surface of the filter screen 14. Water mixed with impurities will be discharged from the slag discharge port through the inclined surface of the guide block 15, which can effectively prevent impurities from remaining on the lower inner wall of the delivery pipe 3. There is no need to use a driving component to clean the water tank 2, which can save energy.

[0026] In the utility model, when in use, the booster pump boosts the external water flow and delivers it to the delivery pipe 3, the filter screen 14 filters out impurities mixed in the water flow, and the filtered water enters the water tank 2 for storage. When the surface of the filter screen 14 is blocked by a large amount of impurities, the screw rod 18 is first rotated. During the relative rotation of the screw rod 18 and the fixed sleeve 17, the slider 19 moves along the screw rod 18 at the same time, and the distance between the slider 19 and the delivery pipe 3 increases. After one of the fixed rods 4 moves, it will be disengaged from the slot. After the other fixed rod 4 moves, the angle between the two hinged rods 12 is reduced, and the distance between the two blocks 21 is reduced. The two blocks 21 will be disengaged from the slide rod 6 and the sealing plate 5 respectively, and then the sealing plate 5, the slide rod 6 and the mounting rod 8 are pressed downward. After the mounting rod 8 moves downward, the cover plate 16 and the slag discharge port can be disengaged.

[0027] As the scraper bar 13 moves downward along with the slide bar 6, it will slide downward closely against the surface of the filter screen 14, thereby scraping off impurities on the surface of the filter screen 14. After the sealing plate 5 moves downward, its lower surface will fit with the lower inner wall of the delivery pipe 3 and have a good seal. After the scraper bar 13 moves down to the lowest point, the slide bar 6 is pulled upward until the scraper bar 13 moves up to the initial position. Finally, a large amount of clean water is poured into the interior of the housing 7 through the fixed pipe 10. The clean water will pass through the rectangular opening into the delivery pipe 3. In the process of water flowing through the filter screen 14 from right to left (such as the attached Figure 3 As shown), the impurities remaining on the surface of the filter screen 14 and the impurities scraped off by the scraper 13 can be washed away, and the water mixed with impurities will be discharged from the slag discharge port through the inclined surface of the guide block 15, so as to quickly clean the filter screen 14 in time, which can effectively avoid the water tank 2 from being polluted, and is conducive to the use of energy-saving box-type intelligent non-negative pressure water supply equipment.

[0028] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
