[0002] Currently, many old factories share a single water tank for both production and fire-fighting water during construction, without any measures to ensure fire-fighting water supply. In the event of a fire or other emergency, fire-fighting water supply cannot be guaranteed, and building a separate fire-fighting water tank would be very expensive. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an automatic water level control device for a water storage tank.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic water level control device for a water storage tank, comprising a water storage tank, a water level gauge installed inside the water storage tank, a water inlet mechanism detachably connected and connected inside the water storage tank, a water outlet pipe detachably connected and connected to the outside of the water outlet pipe, a pressurization mechanism detachably connected and connected to the outside of the pressurization mechanism, a fire-fighting mechanism detachably connected and connected to the outside of the pressurization mechanism, a water-using mechanism detachably connected and connected to the end of the pressurization mechanism, a cover plate assembly provided above the water storage tank, a controller communicatively connected to the water level gauge, and the water inlet mechanism, pressurization mechanism, fire-fighting mechanism, and water-using mechanism all communicatively connected to the controller.

[0005] Preferably, the water inlet mechanism includes an inlet pipe and an electric butterfly valve. One end of the inlet pipe is detachably connected to and communicates with the inside of the water storage tank. The electric butterfly valve is installed on the inlet pipe. The end of the inlet pipe away from the water storage tank is connected to the municipal tap water system. The electric butterfly valve is communicatively connected to the controller.

[0006] Preferably, the pressurization mechanism includes a connecting pipe and multiple pressurization branch pipes. Both ends of the multiple pressurization branch pipes are detachably connected to and communicate with the connecting pipe and the water inlet pipe, respectively. A fire pump is installed on each of the multiple pressurization branch pipes. An electric butterfly valve and a solenoid valve are installed on the connecting pipe. The fire-fighting mechanism is detachably connected to and communicates with the outer periphery of the connecting pipe. The water-using mechanism is detachably connected to and communicates with the end of the connecting pipe. The fire pump, the electric butterfly valve, and the solenoid valve are all communicatively connected to the controller.

[0007] Preferably, the connecting pipe and the water inlet pipe are detachably connected and connected to multiple booster branch pipes, and booster pumps are installed on the multiple booster branch pipes. The booster pumps are communicatively connected to the controller.

[0008] Preferably, the fire-fighting mechanism includes a fire-fighting pipe and a second solenoid valve. The fire-fighting pipe is detachably connected to the outer periphery of the connecting pipe and is in communication with the connecting pipe. The second solenoid valve is installed on the fire-fighting pipe and is communicatively connected to the controller. The end of the fire-fighting pipe is connected to a fire-fighting system.

[0009] Preferably, the water supply mechanism includes a main water supply pipe and multiple branch water supply pipes. The main water supply pipe is detachably connected to and communicates with the end of a connecting pipe. Each of the multiple branch water supply pipes is detachably connected to and communicates with the outer periphery of the main water supply pipe. Each of the multiple branch water supply pipes is equipped with a solenoid valve and is connected to a water supply system. The solenoid valve is communicatively connected to a controller.

[0010] Preferably, the cover plate assembly includes a fixing member and a flat plate. The fixing member is installed on the outer periphery of the water storage tank. A groove is provided above the fixing member. A protrusion is installed below the flat plate. A second protrusion is installed below the first protrusion. The second protrusion and the groove cooperate with each other.

[0011] Preferably, a handle is installed on the top of the flat plate.

[0012] Preferably, the controller is externally connected to a warning device.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] (1) The existing factory uses a water tank for both production water and fire-fighting water, but fire-fighting water is not guaranteed. In this utility model, a water level gauge is installed in the water tank. With the help of the water level gauge and the controller, the water level can be automatically operated according to the preset water level threshold. This process not only avoids the errors and delays that may occur with manual monitoring, but also ensures that the water tank is always maintained in a reasonable water volume range, realizing the efficient use of water resources and thus guaranteeing fire-fighting water.

[0015] (2) The fire-fighting organization and the water-using organization achieve water line separation, which can not only respond quickly when fire-fighting needs arise and give priority to ensuring the supply of fire-fighting water source, but also stably deliver the required amount of water in daily production without interfering with each other, greatly improving practicality and adaptability.

[0016] (3) The external warning light system of the controller can promptly remind the staff to pay attention to the water replenishment when the water level is in the range of 65%-75%, and avoid the risk of production interruption due to water shortage in advance, providing dual protection for production safety and fire safety;

[0017] (4) The cover plate assembly, through the matching structure of protrusion 2 and groove 1, can not only reliably cover the water storage tank to prevent debris from entering and water from evaporating, but also ensure installation stability through simple physical interlocking.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1

[0029] The following is in conjunction with the appendix Figure 1-5 To further describe this utility model, an automatic water level control device for a water storage tank, such as... Figures 1-4As shown, the system includes a water storage tank 1, a water level gauge installed inside the water storage tank 1, a water inlet mechanism detachably connected and connected inside the water storage tank 1, a water outlet pipe 4 detachably connected and connected inside the water storage tank 1, a pressurization mechanism detachably connected and connected to the outer periphery of the water outlet pipe 4, a fire-fighting mechanism detachably connected and connected to the outer periphery of the pressurization mechanism, a water-using mechanism detachably connected and connected to the end of the pressurization mechanism, a cover plate assembly 17 installed above the water storage tank 1, a controller connected to the water level gauge, and the water inlet mechanism, pressurization mechanism, fire-fighting mechanism, and water-using mechanism all connected to the controller.

[0030] like Figures 1-4 As shown, the water inlet mechanism includes an inlet pipe 2 and an electric butterfly valve 3. One end of the inlet pipe 2 is detachably connected to and communicates with the inside of the water storage tank 1. The electric butterfly valve 3 is installed on the inlet pipe 2. The end of the inlet pipe 2 away from the water storage tank 1 is connected to the municipal tap water system. The electric butterfly valve 3 is communicatively connected to the controller.

[0031] like Figures 1-4 As shown, the pressurization mechanism includes a connecting pipe 9 and multiple pressurization branch pipes 5. Both ends of the multiple pressurization branch pipes 5 are detachably connected to and communicate with the connecting pipe 9 and the water inlet pipe 2, respectively. A fire pump 6 is installed on each of the multiple pressurization branch pipes 5. An electric butterfly valve 11 and a solenoid valve 12 are installed on the connecting pipe 9. The fire-fighting mechanism is detachably connected to and communicates with the outer periphery of the connecting pipe 9, and the water-using mechanism is detachably connected to and communicates with the end of the connecting pipe 9. The fire pump 6, the electric butterfly valve 11, and the solenoid valve 12 are all communicatively connected to the controller.

[0032] like Figures 1-4 As shown, multiple booster branch pipes 7 are detachably connected and connected between the connecting pipe 9 and the water inlet pipe 2. Each booster branch pipe 7 is equipped with a booster pump 8, which is connected to the controller.

[0033] like Figures 1-4 As shown, the fire protection system includes a fire pipe 10 and a solenoid valve 14. The fire pipe 10 is detachably connected to the outer periphery of the connecting pipe 9 and is connected to the connecting pipe 9. The solenoid valve 14 is installed on the fire pipe 10 and is connected to the controller. The fire protection system is connected to the end of the fire pipe 10.

[0034] like Figures 1-4 As shown, the water supply system includes a main water pipe 13 and multiple branch water pipes 15. The main water pipe 13 is detachably connected to and communicates with the end of the connecting pipe 9. The multiple branch water pipes 15 are detachably connected to and communicate with the outer periphery of the main water pipe 13. Each branch water pipe 15 is equipped with a solenoid valve 16. Each branch water pipe 15 is externally connected to a water supply system. The solenoid valve 16 is communicatively connected to the controller.

[0035] In this embodiment, the fire protection system is the existing fire protection system in the processing plant.

[0036] In this embodiment, the water system is the existing water system required in the processing plant, such as: production water in the ambient temperature workshop, ambient temperature tap water, tap water in the ice cream workshop, and tap water in the low temperature workshop.

[0037] In this embodiment, the water level gauge is an existing pressure water level gauge, which is installed at the bottom of the water storage tank 1.

[0038] In this embodiment, the end of the water inlet pipe 2 away from the water storage tank 1 is set to be closed.

[0039] In this embodiment, there are 2 booster branch pipes 5 and 5 booster branch pipes 7.

[0040] In this embodiment, the fire pumps 6 on multiple booster branch pipes 1 5 are synchronously controlled by a controller, and the booster pumps 8 on multiple booster branch pipes 2 7 are synchronously controlled by a controller.

[0041] In this embodiment, the electric butterfly valve 11 is located between the main water pipe 13 and the fire pipe 10, and the solenoid valve 12 is located between the electric butterfly valve 11 and the main water pipe 13.

[0042] In this embodiment, when the water level in the water storage tank 1 reaches 75%, the water inlet mechanism replenishes water to 95%. When the water level in the water storage tank 1 reaches 65%, the electric butterfly valve 11 and the solenoid valve 12 close to ensure that the water in the water storage tank 1 can meet the needs of fire-fighting water.

[0043] The working principle of this embodiment is as follows: When the water level in the reservoir 1 reaches 95%, a signal is transmitted to the controller through the water level gauge. When water is needed, the fire pump 6 on the booster branch pipe 1 5, the booster pump 8 on the booster branch pipe 2 7, the electric butterfly valve 2 11, and the solenoid valve 12 are activated. This allows the water in the reservoir 1 to be transported to the main water pipe 13 through the connecting pipe 9, and then distributed to various external water systems (such as production water in the ambient temperature workshop, tap water in the ice cream workshop, etc.) through the solenoid valves 3 16 (controlled by the controller) on multiple water branch pipes 15, meeting the water needs of different scenarios. When the water level in the reservoir 1 reaches 75%, the fire pump 6 on the booster branch pipe 1 7, the electric butterfly valve 2 11, and the solenoid valve 12 are activated. When the electric butterfly valve 3 is activated, the municipal water supply system replenishes the water storage tank 1 through the inlet pipe 2. When the water level in the water storage tank 1 reaches 95%, the electric butterfly valve 3 closes. During this water replenishment process, the fire pump 6 on the booster branch pipe 1 5, the booster pump 8 on the booster branch pipe 2 7, the electric butterfly valve 2 11, and the solenoid valve 12 can be closed or continued to operate as needed for processing and production. When the water level in the water storage tank 1 reaches 65%, the fire pump 6 on the booster branch pipe 1 5, the booster pump 8 on the booster branch pipe 2 7, the electric butterfly valve 2 11, and the solenoid valve 12 all close to ensure that the water in the water storage tank 1 can meet the needs of fire fighting.

[0044] In case of fire-fighting needs, the fire pump 6 and solenoid valve 14 on the booster branch pipe 15 are turned on so that the water in the water storage tank 1 is transported to the external fire protection system through the connecting pipe 9 and the fire pipe 10 to provide water support for fire fighting.

[0045] Example 2

[0046] The main difference between this embodiment and Embodiment 1 is: Figure 4 and Figure 5 As shown, the cover plate assembly 17 includes a fastener 18 and a flat plate 19. The fastener 18 is installed on the outer periphery of the water storage tank 1. A groove is provided above the fastener 18. A protrusion 20 is installed below the flat plate 19. A protrusion 21 is installed below the protrusion 20. The protrusion 21 and the groove are engaged.

[0047] In this embodiment, there is a certain distance between the top of the fixing member 18 and the top of the water storage tank 1, and when the second protrusion 21 and the first groove are engaged, the first protrusion 20 is located between the top of the fixing member 18 and the top of the water storage tank 1.

[0048] The working principle of this embodiment is as follows: The cover plate assembly 17 can cover and protect the water storage tank 1. When the flat plate 19 is placed on the water storage tank 1, the protrusion 21 is embedded in the groove 1. The physical interlocking of the concave and convex structure achieves a stable connection between the two, thereby fixing the flat plate 19 above the water storage tank 1 and playing the role of shielding the top of the water storage tank 1. At the same time, there is a certain distance between the top of the fixing member 18 and the top of the water storage tank 1. When the protrusion 21 cooperates with the groove 1, the protrusion 20 below the flat plate 19 is exactly located between the top of the fixing member 18 and the top of the water storage tank 1. This not only avoids the interference of the protrusion 20 with the cooperation of the protrusion 21 and the groove 1, but also further enhances the installation stability of the flat plate 19 through the limiting effect of the protrusion 20, preventing it from lateral displacement or shaking during the covering process. This ensures that the cover plate assembly 17 can reliably protect the internal environment of the water storage tank 1 and reduce the occurrence of external debris entering or water evaporation.

[0049] Example 3

[0050] The main difference between this embodiment and embodiment 2 is that a handle is installed on the top of the flat plate 19.

[0051] Example 4

[0052] The main difference between this embodiment and Embodiment 1 is that the controller has an external warning device.

[0053] In this embodiment, the warning device is an existing warning light system. The controller can turn the warning light system on and off. When the water level in the water storage tank 1 is between 65% and 75%, the controller turns on the warning light system to remind the staff to observe the water replenishment situation in time and avoid production losses caused by sudden water outages.

[0054] In this invention, the above process can be adjusted according to the on-site conditions.

[0055] In this invention, the controller is capable of automatic control.

[0056] As the technical solution of this utility model, the provided hardware configuration is merely to facilitate the implementation of specific braking control based on the hardware facilities. How to specifically implement braking control and the braking control method are not the technical problems to be solved or the objects of protection of this utility model. Furthermore, the communication methods between the devices all adopt existing communication methods, which are not the focus of this application.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
