Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1:

[0027] Combined with the attached Figures 1 - 3 , the present utility model provides a constant pressure water supply control system for a waterworks, including a base 1, a water tower 11 is provided on the base 1, a water pump 12 is provided on the side of the water tower 11, one end of the water pump 12 is connected to the upper end of the water tower 11 through a water pipe, a support bracket is provided at the lower end of the water pump 12 to support the water pump 12. When in use, the water pump 12 is turned on, and the water pump 12 inputs water into the water tower 11. A filter mechanism 2 is movably connected to the side of the water tower 11. The filter mechanism 2 includes a filter screen 21, a fixed ring 22, and a handle 23. A slot 14 adapted to the filter screen 21 is provided on one side of the water tower 11. The filter screen 21 is inserted into the slot 14. The fixed ring 22 is fixedly connected to the symmetric sides of the filter screen 21, and the handle 23 is fixedly connected to the other side of the filter screen 21. The filter screen 21 filters the water entering the water tower 11. A drain pipe 13 is provided on one side of the lower end of the water tower 11 to convey the outflowing water. After a long time of filtration, the filter screen 21 is pulled out from the slot 14 of the water tower 11 through the handle 23 for cleaning and replacement;

[0028] On the side of the water tower 11, there is a limit mechanism 3 corresponding to the filtering mechanism 2. The limit mechanism 3 includes a connecting ring 31, a spring 32, a limit block 33, a movable column 34, and a connecting plate 35. A holding groove 36 is dug at the center position of the connecting plate 35. Two connecting rings 31 are fixedly connected to the opposite positions on both sides of the water tower 11. The two ends of the spring 32 are respectively connected to the limit block 33 and the connecting ring 31. The movable column 34 is fixedly connected to the lower end of the limit block 33 and is movably connected to the inner side of the connecting ring 31. The lower ends of the two movable columns 34 are respectively fixedly connected to both ends of the connecting plate 35. When installing the filter screen 21, pull down the connecting plate 35 through the holding groove 36, and then push the filter screen 21 into the slot 14 of the water tower 11 to make the positions of the limit block 33 and the fixing ring 22 correspond. Release the holding groove 36, and the limit block 33 rises into the fixing ring 22 under the action of the spring 32 to limit the position of the filter screen 21. The inner parts of the limit block 33 and the fixing ring 22 are adapted to each other, effectively preventing the filter screen 21 from moving in the water tower 11 and avoiding the situation of water leakage caused by the loosening of the filter screen 21 in the water tower 11. The limit ring drives the connecting plate 35 to rise through the movable column 34. When it is necessary to remove the filter screen 21, press the holding groove 36 to avoid the limit of the filter screen 21 by the limit block 33, and then move the filter screen 21 to one side through the handle 23, and the filter screen 21 can be taken out. The connecting plate 35 and the handle 23 are located on the opposite sides of the water tower 11 to avoid mutual influence between the two.

[0029] The working principle of Embodiment 1 is as follows:

[0030] When in use, turn on the water pump 12. The water pump 12 inputs water into the water tower 11. The filter screen 21 filters the water entering the water tower 11. One side of the lower end of the water tower 11 is provided with a drain pipe 13 to discharge the water after it flows out. After a long time of filtration, press the holding groove 36 to avoid the limit of the filter screen 21 by the limit block 33, and then move the filter screen 21 to one side through the handle 23, and the filter screen 21 can be taken out for cleaning and replacement. When installing the filter screen 21, pull down the connecting plate 35 through the holding groove 36, and then push the filter screen 21 into the slot 14 of the water tower 11 to make the positions of the limit block 33 and the fixing ring 22 correspond. Release the holding groove 36, and the limit block 33 rises into the fixing ring 22 under the action of the spring 32 to limit the position of the filter screen 21. The inner parts of the limit block 33 and the fixing ring 22 are adapted to each other, effectively preventing the filter screen 21 from moving in the water tower 11.

[0031] Embodiment 2:

[0032] Combined with the attached Figure 4 As shown, this embodiment provides a constant-pressure water supply control system for a waterworks. The system includes the technical content in Embodiment 1, and the constant-pressure water supply control system in this embodiment further includes a central processor, a first pressure sensor, a second pressure sensor, and a buzzer. Both the first pressure sensor and the second pressure sensor are electrically connected to the buzzer through the central processor.

[0033] In the description of this embodiment, the first pressure sensor and the second pressure sensor are used to detect the water pressure in the water supply system and transmit the detected water pressure signals to the central processing unit. When the water pressure signals received by the central processing unit are higher or lower than the preset value, the central processing unit will prompt the buzzer to sound an alarm.

[0034] In the further description of this embodiment, the first pressure sensor and the second pressure sensor are respectively arranged at the front end and the rear end of the filtration of the filtration mechanism 2. The first pressure sensor is used to monitor the water pressure before filtration, and the second pressure sensor is used to monitor the water pressure after filtration. When the filtration mechanism is clogged to a certain extent, the difference between the water pressure value monitored by the first pressure sensor and the water pressure value monitored by the second pressure sensor will increase. When the difference is greater than the preset value, it indicates that the filtration mechanism has been clogged to a certain degree, and the central processing unit will also prompt the buzzer to sound an alarm. The staff can clean or replace the filtration mechanism according to the alarm prompt. In this way, the stability of the water supply pressure of the water supply system can be ensured.

[0035] As a further description of this embodiment, the constant pressure water supply control system of the water plant in this embodiment further includes a display module 4. The display module 4 is located on one side of the buzzer at the upper end of the water tower 11. The display module 4 in this embodiment can be a display screen. The display screen is connected to the central processing unit, and the pressure values feedback by the first pressure sensor and the second pressure sensor, as well as the pressure difference between the first pressure sensor and the second pressure sensor, are displayed on the display screen. The staff can judge whether it is necessary to clean or replace the filtration mechanism based on the pressure values feedback by the first pressure sensor and the second pressure sensor and the pressure difference between the first pressure sensor and the second pressure sensor displayed on the display screen.

[0036] The above describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the purpose of the creation of the present invention, they shall fall within the protection scope of the present invention.
