Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 2-4As shown, one embodiment of this utility model is provided: a constant pressure water replenishment device with alarm function, including a water storage tank 1, a water pump 2 fixedly connected to the top of the water storage tank 1, a connecting pipe 3 fixedly connected to the inlet of the water pump 2, a filter box 4 fixedly connected to the other end of the connecting pipe 3, a collection plate 5 provided on the inner wall of the filter box 4, a filter screen 6 fixedly connected to the inner wall of the collection plate 5, a knob 7 rotatably connected to the inner wall of the collection plate 5, a rotating frame 9 fixedly connected to the rear end of the knob 7, rotating rods 10 rotatably connected to both sides of the inner wall of the rotating frame 9, and a locking block 11 rotatably connected to the other end of each rotating rod 10. The outer wall of the locking block 11 is slidably connected to the inner wall of the collection plate 5. The inner wall of the filter box 4 is provided with slots 12 on both sides, and the outer wall of the locking block 11 is set on the inner wall of the slot 12. The shape of the locking block 11 fits the slot 12. A torsion spring 8 is fixedly connected to the outer wall of the knob 7, and the other end of the torsion spring 8 is fixedly connected to the front end of the collection plate 5 for processing the collected impurities.

[0029] Specifically, when installing the collection plate 5, first turn the knob 7 and insert the collection plate 5 into the filter box 4, ensuring the sealing ring on the inner wall of the collection plate 5 contacts the inner wall of the filter box 4. Then, release the knob 7, causing the locking blocks 11 on both sides to slide outwards, locking the locking blocks 11 into the slots 12. This completes the installation of the collection plate 5. (Refer to...) Figure 5 The pressure sensor 14 is protected by a housing. The pressure sensor 14 converts pressure signals into electrical signals through physical effects. Piezoresistive sensors utilize the piezoresistive effect of silicon material; the change in resistance under pressure causes an imbalance in the bridge circuit, resulting in an output voltage. Capacitive sensors change the capacitance value by varying the electrode spacing. Piezoelectric sensors rely on the charge generated by a crystal under pressure, which is amplified and transmitted to the display screen in the controller. Before adding water to the storage tank 1, the water is filtered through the filter screen 6, and impurities are stored. The collection plate 5 can be removed by turning the knob 7 for easy processing of impurities. This system effectively intercepts large suspended particles such as silt and rust in the water, preventing these impurities from flowing into the system's pipes and equipment with the replenished water, ensuring clean replenished water quality and laying the foundation for stable system operation.

[0030] Reference Figure 1 , Figure 6 and Figure 7As shown, a mounting frame 15 is fixedly connected to the front end of the water tank 1. An alarm light 19 is installed on the inner wall of the mounting frame 15. A pressure sensor 14 is fixedly connected to the inner wall of the water tank 1. A connecting frame 20 is fixedly connected to the rear end of the alarm light 19. Springs 21 are fixedly connected to both sides of the inner wall of the connecting frame 20. Limiting blocks 13 are fixedly connected to the other end of each spring 21. Limiting grooves 16 are opened on both sides of the inner wall of the mounting frame 15. The outer walls of the limiting blocks 13 are set on the inner walls of the limiting grooves 16. The shape of the limiting blocks 13 fits the limiting grooves 16. Push rods 17 are slidably connected to both sides of the inner wall of the mounting frame 15. Springs 18 are fixedly connected to both sides of the outer walls of the push rods 17. The other end of each spring 18 is fixedly connected to the outer wall of the mounting frame 15 for the installation and removal of the alarm light 19.

[0031] Specifically, a water outlet valve is installed at the bottom of the water storage tank 1 to drain the water in the water storage tank 1. Secondly, a controller is installed at the front end of the water storage tank 1. The controller is electrically connected to the water pump 2, the pressure sensor 14 and the alarm light 19. By installing a detachable alarm light 19, when the alarm light 19 malfunctions, the staff does not need to disassemble the entire device on a large scale. They can simply remove the alarm light 19 for inspection, repair or replacement, which shortens the troubleshooting and repair time and reduces the system downtime caused by equipment maintenance.

[0032] Working principle: First, water is added into the filter box 4 through the inlet on the left side of the filter box 4. The water is filtered through the internal filter screen 6, and the filtered impurities are placed in the collection plate 5. The pressure sensor 14 inside the water storage tank 1 monitors the hydraulic pressure of the water storage tank 1 in real time. When the hydraulic pressure is low, the front alarm light 19 is activated to warn the staff. The water pump 2 is started through the controller. The water pump 2 draws out the filtered water from the inner wall of the filter box 4 through the connecting pipe 3 and stores it in the water storage tank 1. After the internal pressure is appropriate, the water pump 2 is turned off. Next, when it is necessary to process the collected impurities, simply turn the knob 7. The knob 7 drives the rotating frame 9 to rotate, and drives the rotating rods 10 on both sides to rotate, thereby driving the locking blocks 11 on both sides to slide inward. The locking blocks 11 are removed from the locking slots 12, and the collection plate 5 can be taken out forward to process the collected impurities.

[0033] When the alarm light 19 needs to be disassembled and replaced, push the push rods 17 on both sides inward. The push rods 17 cause the limit blocks 13 on both sides to retract inward, and remove the limit blocks 13 from the limit grooves 16. Then the alarm light 19 and the connecting frame 20 can be taken out forward. When the alarm light 19 needs to be installed, simply press the limit blocks 13 on both sides inward and insert the connecting frame 20 into the mounting frame 15. After installation, the limit blocks 13 are inserted into the limit grooves 16 by the springs 21 on both sides to complete the installation.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
