[0022] The present utility model provides an energy-saving fully automatic variable-frequency constant-pressure water supply device as Figures 1-4 shown, which includes a pressure tank 1. An inlet flange 2 is fixedly arranged at the top end of the pressure tank 1, an outlet pipe 3 is fixedly arranged at the bottom end of the pressure tank 1, an extension pipe 4 is fixedly arranged at one end of the outlet pipe 3, a plurality of water pumps 5 are arranged on one side of the pressure tank 1, an inlet pipe 6 is fixedly arranged at the input end of the water pump 5, and the inlet pipe 6 is connected to the extension pipe 4. A water supply pipe 7 is fixedly arranged at the output end of the water pump 5;

[0023] Specifically, an installation seat 8 is penetrated through the top end of the outer side wall of the pressure tank 1, and the installation seat 8 is arranged in an annular structure. An activity seat 9 is arranged at the notch of the installation seat 8, and the activity seat 9 is fixedly connected with the installation seat 8 through bolts. A filter screen 10 is fixedly arranged in the middle of the inner side wall of the activity seat 9. The filter screen 10 is inserted into the inside of the pressure tank 1. The filter screen 10 is arranged in a "C" shape structure, and the opening of the filter screen 10 faces upward. The design with the opening facing upward facilitates the filter screen 10 to collect impurities;

[0024] More specifically, an annular seat 11 is fixedly arranged at the top end inside the pressure tank 1, and the annular seat 11 corresponds to the filter screen 10. A partition plate 12 is fixedly arranged at the top end inside the pressure tank 1, and the partition plate 12 is arranged between the installation seat 8 and the annular seat 11. An arc-shaped plate 13 is fixedly arranged at the top end of the inner side wall of the partition plate 12, and the arc-shaped plate 13 corresponds to the filter screen 10. The arc-shaped plate 13 not only reduces the pressure on the side of the filter screen 10, but also can guide the water into the opening at the top end of the filter screen 10;

[0025] And, a horizontal plane 14 is arranged at the top end of the filter screen 10, and the horizontal plane 14 is flush with the top end of the arc-shaped plate 13. A support frame 15 is arranged at the top end inside the filter screen 10. A plurality of support rods 16 are fixedly arranged inside the support frame 15.

[0027] The working principle of the utility model:

[0028] When the device is in use, the water in the water supply pipeline enters the pressure tank 1 through the inlet flange 2, and after being filtered by the filter screen 10, it enters the lower half of the pressure tank 1. The water in the lower half of the pressure tank 1 enters the water pump 5 through the outlet pipe 3 and the extension pipe 4, and is pressurized by the water pump 5 and then conveyed to the water supply pipe 7 to realize the water supply to the water use pipe network;

[0029] During the filtering process of the filter screen 10, the water enters the upper part of the pressure tank 1 through the inlet flange 2 and accumulates above the partition plate 12, and then enters the opening above the filter screen 10 under the guidance of the arc-shaped plate 13. After the water enters the filter screen 10, the impurities in the water are filtered by the filter screen 10, and the impurities accumulate inside the filter screen 10. When cleaning the filter screen 10, remove the bolts on the outer side of the activity seat 9, and the disassembly of the activity seat 9 and the filter screen 10 can be realized, so as to facilitate the cleaning of the impurities inside the filter screen 10.
