Description

Technical fields:

[0001] This utility model relates to the field of drainage and overflow, specifically to an automatic overflow prevention device. Background technology:

[0002] In daily life and industrial production, the problem of container overflow has always been a key concern. Traditional overflow prevention devices mostly employ simple mechanical structures, such as float valves, which rely on a float rising and falling with the water level to control the opening and closing of the inlet. However, these mechanical structures are prone to jamming and wear during long-term use, leading to overflow failure and unreliable overflow prevention. Furthermore, traditional devices often lack precise liquid level monitoring and automated control capabilities, requiring real-time manual monitoring. When unattended, uncontrolled water inflow can easily cause overflows, wasting water resources and potentially leading to equipment damage, a humid environment, and other problems. In addition, some existing overflow prevention devices have inadequate drainage designs, resulting in low drainage efficiency when overflow occurs, failing to promptly remove excess liquid and further exacerbating the adverse effects of overflow. Therefore, there is an urgent need for an overflow prevention device that can achieve automatic monitoring, precise control, and efficient drainage to address the problems of low reliability and insufficient automation in existing technologies. To this end, this invention proposes an automatic overflow prevention device to overcome the shortcomings and deficiencies of existing technologies. Utility model content:

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an automatic overflow prevention device.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An automatic overflow prevention device includes a container, a water inlet, and an overflow prevention component. The bottom of the container is connected to a spring-loaded plug, and the bottom of the spring-loaded plug is connected to a water outlet pipe. An overflow prevention hole is opened on the side of the container, and the overflow prevention hole is connected to an overflow prevention pipe through a waterproof plug. The end of the overflow prevention pipe is connected to the overflow prevention component. The water inlet consists of a water inlet tap and a water inlet pipe, and the water inlet tap is connected to the water inlet pipe.

[0006] Preferably, the overflow prevention component includes a cavity, a connecting pipe, a first liquid level sensor, a second liquid level sensor, a drain pipe, a first solenoid valve, a second solenoid valve, and a controller. The top of the cavity is connected to the overflow prevention pipe, and the bottom of the cavity is connected to the outlet pipe through the drain pipe. The first solenoid valve is connected to the drain pipe. The two ends of the connecting pipe are respectively connected to the upper and lower ends of the side of the cavity. The upper end of the connecting pipe is connected to the first liquid level sensor, and the lower end of the connecting pipe is connected to the second liquid level sensor. The second solenoid valve is installed on the inlet pipe, and the controller is installed on the side of the cavity.

[0007] Preferably, the first liquid level sensor, the second liquid level sensor, the first solenoid valve, and the second solenoid valve are electrically connected to the controller.

[0008] Preferably, the water inlet faucet is installed on the side of the container via a mounting bracket.

[0009] Preferably, the end of the overflow prevention pipe is connected to an S-shaped pipe.

[0010] The beneficial effects of this utility model are as follows: The automatic overflow prevention device provided by this utility model, through the combination of dual liquid level sensors and a controller, achieves accurate monitoring and automated control of the liquid level in the container. It can promptly close the inlet valve when the liquid level reaches the warning height to prevent overflow, thus improving the reliability and intelligence level of overflow prevention.

[0014] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0015] like Figure 1-3As shown, an automatic overflow prevention device includes a container 001, a water inlet 002, and an overflow prevention component 003. A spring stopper 110 is connected to the bottom of the container 001, and a water outlet pipe 120 is connected to the bottom of the spring stopper 110. Under normal use, the spring stopper 110 can be kept closed by its own weight or external control. When drainage is required, the spring stopper 110 can be opened manually or automatically to allow the liquid in the container 001 to be discharged through the water outlet pipe 120. An overflow prevention hole 130 is provided on the side of the container 001. The overflow prevention hole 130 is connected to an overflow prevention pipe 004 through a waterproof plug 140. The overflow prevention component 003 is connected to the end of the overflow prevention pipe 004. The water inlet 002 consists of a water inlet tap 210 and a water inlet pipe 220, and the water inlet tap 210 is connected to the water inlet pipe 220.

[0016] Further optimizations to this solution include: Figure 1-3 As shown: The overflow prevention component 003 includes a cavity 310, a connecting pipe 320, a first liquid level sensor 330, a second liquid level sensor 340, a drain pipe 350, a first solenoid valve 360, a second solenoid valve 370, and a controller 380. The top of the cavity 310 is connected to the overflow prevention pipe 004, and the bottom of the cavity 310 is connected to the outlet pipe 130 through the drain pipe 350. The first solenoid valve 360 ​​is connected to the drain pipe 350. The two ends of the connecting pipe 320 are respectively connected to the upper and lower ends of the side of the cavity 310. The upper end of the connecting pipe 320 is connected to the first liquid level sensor 330, and the lower end of the connecting pipe 320 is connected to the second liquid level sensor 340. The first liquid level sensor 330 and the second liquid level sensor 340 are respectively installed in specific positions to monitor the changes in liquid level in the cavity 310 in real time, convert the liquid level information into electrical signals, and transmit them to the controller 380. The first liquid level sensor 330 is installed near the top of the cavity 310 as a key node for overflow warning. Once the liquid level is detected, it immediately feeds back the signal to the controller 380. The second liquid level sensor 340 is installed in the lower part of the cavity 310 to monitor the completion of drainage and provide a basis for system reset. The second solenoid valve 370 is installed on the water inlet pipe 220. The controller 380 is installed on the side of the cavity 310.

[0017] Further optimizations to this solution include: Figure 1-3 As shown: the first liquid level sensor 330, the second liquid level sensor 340, the first solenoid valve 360, and the second solenoid valve 370 are electrically connected to the controller 380.

[0018] Further optimizations to this solution include: Figure 1-3 As shown: The water inlet faucet 210 is installed on the side of container 001 via the mounting base 230.

[0019] Further optimizations to this solution include: Figure 1-3As shown: The end of the overflow pipe 004 is connected to an S-shaped pipe 410. The S-shaped pipe 410 is designed using the water seal principle, which can effectively prevent odors from external pipes from entering the container 001.

[0020] The method or principle of use of this utility model is as follows: When water is injected into container 001, the water inlet tap 210 is opened, and liquid enters container 001 through water inlet pipe 220. As the water level rises, if the water level does not reach the overflow hole 130, the overflow prevention component 003 does not work; when the water level rises to the overflow hole 130, liquid flows into cavity 310, and the liquid level in cavity 310 rises. When the liquid level reaches the detection position of the first liquid level sensor 330, the first liquid level sensor 330 sends a signal to the controller 380, and the controller 380 controls the second solenoid valve 370 to close, stopping the water intake, and at the same time controls the first solenoid valve 360 ​​to open, and the liquid in cavity 310 is discharged into outlet pipe 120 through drain pipe 350 and then discharged. When the liquid level in cavity 310 drops to the detection position of the second liquid level sensor 340, the second liquid level sensor 340 sends a signal to the controller 380, and the controller 380 controls the first solenoid valve 360 ​​to close, completing one overflow prevention operation. This automatic monitoring and control system effectively protects against water overflow from container 001.

[0021] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
