Description

Technical Field

[0001] This utility model belongs to the technical field of automatic water replenishment devices, specifically relating to an automatic water replenishment device for fire-fighting water tanks. Background Technology

[0002] In fire protection systems, fire water tanks are important facilities for storing fire-fighting water, and the stability of their water levels is crucial for ensuring the timely supply of fire-fighting water.

[0003] Patent application (publication number: CN207553210U) discloses an automatic water replenishment device for fire-fighting water tanks. The technical solution comprises a water tank, a float lifting slide, a trigger slide, a stop trigger, a control box, a replenishment trigger, a pump support platform, and a pump. A float is installed inside the float lifting slide. The stop trigger is equipped with a stop controller and a stop circuit. The replenishment trigger is equipped with a replenishment controller and a replenishment circuit. The pump is also equipped with control cables, an inlet valve, a delivery valve, and a delivery pipe. The float in this mechanism is made of wood. When the water level in the tank rises or falls to a specific range, it can trigger replenishment and stop commands to control the pump's opening and closing. This mechanism has a simple structure and is easy to operate. It can automatically replenish and stop water according to the water consumption in the fire-fighting water tank, preventing excessive water storage and overflow of fire-fighting water. The water storage operation is more intelligent and controllable.

[0004] In the aforementioned application, since both the water replenishment trigger and the water stop trigger are fixedly connected to the trigger slide, the setting of the highest water level is fixed, lacking an effective water level adjustment mechanism, making it difficult to achieve dynamic adjustment of the highest water level.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This automatic water replenishment device for fire-fighting water tanks uses a lever to move a second magnetic plate up and down along a slide rail. The magnetic attraction between the first and second magnetic plates drives the first magnetic plate to move a sliding frame synchronously along a slide rail, thereby adjusting the height of the water level regulator. This allows for dynamic control of the water replenishment in the fire-fighting water tank based on actual water demand. For example, during seasons with low fire-fighting water demand or fire drills, the height of the water level regulator can be lowered to reduce the amount of water replenished.

This device is particularly suitable for dynamic water-saving control needs in water-scarce areas or during peak water usage periods. A thin acrylic sheet is used to visually display the water level and the position of the magnetic plates. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This utility model provides the following technical solution: an automatic water replenishment device for fire water tanks, comprising:

[0029] Fire water tank 1, with an acrylic sheet 2 fixedly connected to one side of the fire water tank 1;

[0030] A float switch 3 is sealed with a wire 4, and a water level regulator 5 is sleeved on the surface of the wire 4.

[0031] A slide rail 6 is fixedly connected to the bottom of the fire water tank 1. A sliding frame 7 is slidably installed inside the slide rail 6. The sliding frame 7 is fixedly connected to the water level regulator 5. A magnetic plate 8 is fixedly connected to one end of the sliding frame 7.

[0032] Magnetic plate 29, magnetic plate 18 and magnetic plate 29 are located on the inner and outer sides of acrylic sheet 2 respectively. Magnetic plate 29 is attracted to magnetic plate 18 through acrylic sheet 2. A sliding groove 10 is fixedly connected to the outer side of acrylic sheet 2. Magnetic plate 29 is slidably installed inside the sliding groove 10. A lever plate 11 is fixedly connected to the surface of magnetic plate 29.

[0033] In this embodiment, the lever 11 drives the magnetic plate 2 9 to slide up and down along the slide groove 10. Utilizing the magnetic attraction between the magnetic plate 1 8 and the magnetic plate 2 9, the magnetic plate 1 8 drives the sliding frame 7 to move synchronously along the slide rail 6, thereby adjusting the height of the water level regulator 5. The amount of water replenished in the fire water tank 1 can be dynamically controlled according to actual water demand. For example, in seasons with low fire water demand or during fire drills, the height of the water level regulator 5 can be lowered to reduce the amount of water replenished. In emergency situations with high fire water demand, the height of the water level regulator 5 can be raised to ensure that the fire water tank 1 has sufficient water. This is especially suitable for dynamic water-saving control needs in water-scarce areas or during peak water demand periods. The acrylic sheet 2 is used to visually display the water level and the position of the magnetic plate.

[0034] Furthermore, an electrical control box 12 is fixedly installed on one side of the fire water tank 1. The electrical control box 12 includes an air switch, a contactor, a switching power supply and an intermediate relay. The contactor is electrically connected to the air switch.

[0035] Furthermore, a water pump 13 is fixedly installed on one side of the fire water tank 1, and the water pump 13 and the wire 4 are electrically connected to the contactor.

[0036] Specifically, by placing the float switch 3 inside the fire water tank 1, one end of the wire 4 is sealed to the float switch 3 with a sealing sleeve, and the other end passes through the water level regulator 5 (the water level regulator 5 is fixed on the sliding frame 7), extends to the two pulleys 19 of the tension adjustment device, and finally connects to the contactor in the electrical control box 12. The contactor is electrically connected to the air switch to control the on and off of the circuit. When the water level drops to the set value, the float switch 3 triggers a signal, which is transmitted to the electrical control box 12 through the wire 4. After receiving the signal, the contactor in the electrical control box 12 controls the water pump 13 to start and simultaneously opens the solenoid valve 26. The water pump 13 draws in external water through the inlet pipe 24, and enters the fire water tank 1 through the outlet pipe 25, the solenoid valve 26, and the water supply pipe 27 to achieve automatic water replenishment. When the water level rises to the set value, the float switch 3 triggers a signal again, and the electrical control box 12 controls the water pump 13 to stop running and the solenoid valve 26 to close, stopping water replenishment.

[0037] Furthermore, it also includes:

[0038] Tension adjustment device, the tension adjustment device includes:

[0039] A servo motor 14 is provided, and a base 15 is fixedly mounted on the lower surface of the servo motor 14. The base 15 is fixedly mounted on the upper surface of the acrylic sheet 2. A reducer 16 is fixedly connected to the output end of the servo motor 14. A lead screw 17 is fixedly connected to the output end of the reducer 16. A slide block 18 is threaded onto the surface of the lead screw 17. A spool 19 is rotatably mounted on one side of the slide block 18. A guide rod 20 is fixedly mounted on one side of the servo motor 14. The slide block 18 and the guide rod 20 are slidably connected. A limit plate 21 is fixedly connected to one end of the guide rod 20.

[0040] Furthermore, the reels 19 are symmetrically distributed, and the wire 4 passes through the symmetrical reels 19.

[0041] Specifically, during use, when the wire 4 becomes slack, the servo motor 14 is started. The servo motor 14 drives the lead screw 17 to rotate through the reducer 16. The rotation of the lead screw 17 causes the slide 18 to slide along the guide rod 20. The slide 18 is equipped with a wire wheel 19. Since the wire 4 passes between the symmetrical wire wheels 19, the movement of the slide 18 will change the position of the wire wheels 19, thereby adjusting the tension of the wire 4 and keeping the wire 4 in a suitable tension state to ensure the stable operation of the device.

[0042] Furthermore, a bracket 22 is fixedly connected to the upper surface of the fire water tank 1, and a protective canopy 23 is installed on the surface of the bracket 22.

[0043] Specifically, the protective canopy 23 covers the opening above the fire water tank 1, which can block sunlight and prevent debris from falling into the fire water tank 1.

[0044] Furthermore, the input end of the water pump 13 is fixedly connected to the inlet pipe 24, the output end of the water pump 13 is fixedly connected to the outlet pipe 25, the end of the outlet pipe 25 is equipped with a solenoid valve 26, the end of the solenoid valve 26 is equipped with a water supply pipe 27, the water supply pipe 27 extends into the fire water tank 1 and is sealed to it.

[0045] Specifically, when the water level drops, the float switch 3 swings down to the set angle, the internal micro switch opens, the contactor is de-energized, its main contacts close, and the water pump 13 and solenoid valve 26 are simultaneously energized. Municipal tap water enters the fire water tank 1 through the inlet pipe 24 → water pump 13 → outlet pipe 25 → solenoid valve 26 → water supply pipe 27. As the water level rises, the float switch 3 returns to the horizontal position, the micro switch closes, the contactor coil is energized, the main contacts open, and the water pump 13 and solenoid valve 26 are simultaneously de-energized, ending the water supply.

[0046] The working principle or usage process of this utility model is as follows: Personnel visually inspect the actual water level in the pool. If the current water level is lower than the required value, the lever 11 is moved upwards, causing the second magnetic plate 9 to move upwards along the slide groove 10. The first magnetic plate 8 is attracted by the magnetic force and moves upwards synchronously, driving the water level regulator 5 to rise. Conversely, it moves downwards, realizing the dynamic preset of the water replenishment amount. By starting the servo motor 14, the reducer 16 drives the lead screw 17 to rotate, and the slide 18 slides along the guide rod 20 in a direction away from the servo motor 14 (the limit plate 21 limits the overtravel of the slide 18). The slide 18 drives the two pulleys 19 to move synchronously, applying lateral tension to the wire 4 until the wire 4 reaches the appropriate tension. When the water level in the fire water pool 1 is low... When the water level reaches the lower threshold set by the water level regulator 5, the float switch 3 sinks as the water level drops, triggering the internal contacts to close. The signal is transmitted to the contactor in the electrical control box 12 via the wire 4. The contactor connects the power supply, driving the water pump 13 to start, and at the same time, the solenoid valve 26 opens. External water flows into the fire water tank 1 through the inlet pipe 24 → water pump 13 → outlet pipe 25 → solenoid valve 26 → water supply pipe 27. As the water level rises, the float switch 3 floats up with the water level. When the water level reaches the upper threshold set by the water level regulator 5, the float switch 3 triggers the internal contacts to open, and the signal is transmitted to the electrical control box 12. The contactor disconnects the power supply, the water pump 13 stops running, the solenoid valve 26 closes, and the water supply process ends.

[0047] Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the utility model. The selection and detailed description of these embodiments in this specification are for the purpose of better explaining the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
