Description

Technical Field

[0001] This utility model relates to the field of water tank technology, and in particular to a water tank with a leakage alarm function. Background Technology

[0002] Leak alarm water tanks are intelligent water storage devices that integrate sensors and alarm systems to monitor for leaks in the tank and its surrounding environment in real time, issuing timely alerts to prevent water waste, property damage, or safety hazards caused by leaks. They are widely used in homes, commercial buildings, industrial facilities, data centers, and other scenarios with high waterproofing requirements.

[0003] The water tank is also equipped with a structure to indicate the water level, which can be indicated by a U-shaped tube. However, the end of the U-shaped tube that is not connected to the water tank needs to be connected to the gas. This allows dust and impurities inside the gas to enter the U-shaped tube and contaminate the water inside the water tank. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a water tank with a water leakage alarm function.

[0005] The technical solution of this utility model: A water tank body with a water leakage alarm function, including a water tank body and a support frame fixedly installed inside the water tank body, and further including:

[0006] A protective box is fixedly installed on the outside of the water tank body. A water storage cavity is provided between the protective box and the water tank body. A liquid level sensor is fixedly installed at the bottom of the water storage cavity.

[0007] A connecting pipe is fixedly installed on the water tank body. The connecting pipe indicates the water level inside the water tank body. An exhaust component is fixedly installed on the top of the connecting pipe. When the air pressure inside the connecting pipe increases, the exhaust component controls the top of the connecting pipe to connect with the outside and slowly seals the connecting pipe.

[0008] Optionally, the exhaust component includes a bent pipe fixedly installed at the top of the connecting pipe, a connector fixedly installed at the bottom of the bent pipe, a plurality of exhaust holes provided on the connector, and a sealing component fixedly installed on the exhaust holes.

[0009] Optionally, the sealing assembly includes a first sealing block fixedly installed on the connector. The first sealing block has a fine hole and a coarse hole with a diameter larger than the fine hole. The first sealing block has multiple connecting holes communicating with the fine hole and multiple bottom holes communicating with the coarse hole. A slide rod is slidably installed inside the first sealing block. A second sealing block is fixedly installed on the slide rod. The second sealing block is located inside the coarse hole. A spring is fixedly installed between the second sealing block and the connector.

[0010] Optionally, the exhaust component further includes a soft-return assembly connected to the second sealing block. The soft-return assembly includes a pull rod fixedly installed on the second sealing block, a limit cylinder fixedly installed on the connector, a sealing block slidably installed inside the limit cylinder, the sealing block being fixedly connected to the pull rod, and the two ends of the limit cylinder being connected to a thick pipe and a thin pipe, respectively. The inner diameter of the thick pipe is larger than that of the thin pipe. A first one-way valve is fixedly installed on the thick pipe, and a second one-way valve is fixedly installed on the thin pipe. The first one-way valve and the second one-way valve are in opposite directions.

[0011] Optionally, a third one-way valve is fixedly installed on the connector, which allows gas to enter the connector in one direction only, and the third one-way valve is equipped with a filter screen.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] By installing the venting component, external impurities can be prevented from entering the connecting pipe, while the gas inside the connecting pipe can be completely discharged as the liquid level increases. This prevents pollutants from entering the water tank through the connecting pipe and contaminating it, and also avoids the accumulation of air pressure inside the connecting pipe, which could lead to inaccurate water level readings within the tank.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Examples, such as Figure 1 As shown, the present invention proposes a water tank with a leakage alarm function, including a water tank body 1 and a support frame 101 fixedly installed inside the water tank body 1, and a protective box 2 fixedly installed outside the water tank body 1. A water storage cavity 201 is provided between the protective box 2 and the water tank body 1. A liquid level sensor is fixedly installed at the bottom of the water storage cavity 201. When water leaks inside the water tank body 1, it will flow into the water storage cavity 201. Then, the liquid level sensor detects the change in the liquid level inside the water storage cavity, thereby determining whether the water tank body 1 has leaked. The water tank body 1 should be equipped with a buzzer, which is linked with the liquid level sensor. When the liquid level sensor detects a change in the water level, the buzzer will sound an alarm.

[0024] Furthermore, the water tank body 1 is provided with an overflow hole 102, a water inlet hole 103, a water outlet 104, and a drain hole 105. The overflow hole 102, the water inlet hole 103, the water outlet 104, and the drain hole 105 all penetrate one side of the protective box 2 and are sealed with the protective box 2. The overflow hole 102 prevents water from continuously entering the water tank body 1 and prevents the water pressure inside the water tank body 1 from increasing. Water is supplied to the water tank body 1 through the water inlet hole 103, and the water inside the water tank body 1 is discharged through the water outlet 104. The sediment inside the water tank is discharged through the drain hole 105.

[0025] like Figures 2 to 5As shown, this embodiment also includes a connecting pipe 106 fixedly installed on the water tank body 1. The connecting pipe 106 indicates the water level inside the water tank body 1. The connecting pipe 106 and the water tank body 1 form a U-shaped pipe. According to the principle of the U-shaped pipe, the water level inside the connecting pipe 106 can be kept equal to the water level inside the water tank body 1. Thus, the water level inside the water tank body 1 can be determined by the connecting pipe 106. An exhaust component 3 is fixedly installed on the top of the connecting pipe 106. When the air pressure inside the connecting pipe 106 increases, the exhaust component 3 controls the top of the connecting pipe 106 to connect with the outside and slowly seals the connecting pipe 106. In order to prevent pollutants from entering the water tank body 1 through the connecting pipe 106, it is necessary to restrict the opening of the connecting pipe 106. When the liquid level inside the connecting pipe 106 rises, it will compress the gas inside the connecting pipe 106, thereby increasing the air pressure inside the connecting pipe 106.

[0026] Furthermore, the exhaust component includes a bent pipe 301 fixedly installed at the top of the connecting pipe 106, a connector 302 fixedly installed at the bottom of the bent pipe 301, a plurality of exhaust holes 303 provided on the connector 302, and a sealing assembly fixedly installed on the exhaust holes 303. The sealing assembly includes a first sealing block 304 fixedly installed on the connector 302, the first sealing block 304 having a fine hole 305 and a coarse hole 306 with a diameter larger than the fine hole 305, a plurality of connecting holes 318 communicating with the fine holes 305 and a plurality of bottom holes 316 communicating with the coarse holes 306, a sliding rod 307 slidably installed inside the first sealing block 304, a second sealing block 308 fixedly installed on the sliding rod 307, the second sealing block 308 located inside the coarse hole 306, and a spring 319 fixedly installed between the second sealing block 308 and the connector 302. When the air pressure inside the connecting pipe 106 increases, it will drive the spring 319. 9. Move the second sealing block 308 away from the fine hole 305, and then allow the gas inside the connecting pipe 106 to be discharged through the connecting hole 318, fine hole 305, coarse hole 306 and bottom hole 316. This prevents the gas from pushing and causing the connecting pipe 106 to fail to accurately reflect the water level inside the water tank body 1. When venting is not required, the fine hole 305 can be blocked by the action of the spring 319, thereby preventing impurities from entering the connecting pipe 106. The cooperation of the spring 319, the fine hole 305 and the coarse hole 306 of the second sealing block 308 forms a one-way valve. In order to be discharged, the gas needs to overcome the elastic force of the spring 319. Therefore, if the gas inside the connecting pipe 106 is not completely discharged, the second sealing block 308 can be reset again by the action of the spring 319. This may cause the gas pressure inside the connecting pipe 106 to accumulate, resulting in the connecting pipe 106 failing to accurately reflect the water level inside the water tank body 1.

[0027] It is worth noting that a third check valve 317 is fixedly installed on the connector 302. The third check valve 317 allows gas to enter the interior of the connector 302 in one direction. The third check valve 317 is equipped with a filter screen. When the water level inside the connecting pipe 106 drops with the water level of the water tank body 1, air will enter the interior of the connecting pipe through the third check valve 317 and filter impurities through the filter screen.

[0028] In this embodiment, the exhaust component 3 further includes a soft-return assembly connected to the second sealing block 308. The soft-return assembly includes a pull rod 309 fixedly installed on the second sealing block 308, a limit cylinder 310 fixedly installed on the connector 302, a sealing block 311 slidably installed inside the limit cylinder 310, the sealing block 311 being fixedly connected to the pull rod 309, and the two ends of the limit cylinder 310 being connected to a thick pipe 312 and a thin pipe 313 respectively. The inner diameter of the thick pipe 312 is larger than that of the thin pipe 313. A first one-way valve 314 is fixedly installed on the thick pipe 312, and a second one-way valve 315 is fixedly installed on the thin pipe 313. The first one-way valve 314 and the second one-way valve 315 are in opposite directions. When the second sealing block 308... When the second sealing block 308 moves away from the orifice 305, it will cause the sealing block 311 to move. The coarse pipe 312, the fine pipe 313, and the limiting cylinder 310 are all filled with hydraulic medium. The hydraulic medium is a liquid that cannot be compressed under working conditions. Therefore, when the second sealing block 308 moves the sealing block 311 downward, the hydraulic medium will circulate through the coarse pipe 312 and maintain a relatively fast flow rate. When it is reset under the action of the spring 319, the hydraulic medium will flow through the fine pipe 313. Due to the limitation of the pipe diameter, the flow rate will also slow down, so that the second sealing block 308 can slowly seal the orifice 305, thereby ensuring that other contents inside the connecting pipe 106 can be completely discharged.

[0029] Working principle: When the liquid level inside the connecting pipe 106 rises, it will compress the gas inside the connecting pipe 106, thereby increasing the gas pressure inside the connecting pipe 106. This will drive the spring 319 to move, causing the second sealing block 308 to disengage from the narrow hole 305. Subsequently, the gas inside the connecting pipe 106 can be discharged through the connecting hole 318, the narrow hole 305, the coarse hole 306, and the bottom hole 316. This prevents the gas from pushing and causing the connecting pipe 106 to fail to accurately reflect the water level inside the water tank body 1. When the second sealing block 308 moves away from the narrow hole 305, it will drive the sealing block 311 to move, and the coarse pipe... Hydraulic medium is filled in the thick tube 312, the thin tube 313, and the limiting cylinder 310. The hydraulic medium is a liquid that cannot be compressed under working conditions. Therefore, when the second sealing block 308 moves the sealing block 311 downward, the hydraulic medium will circulate through the thick tube 312 and maintain a relatively fast flow rate. When the spring 319 resets the cylinder, the hydraulic medium will flow through the thin tube 313. Due to the limitation of the pipe diameter, the flow rate will also slow down, which allows the second sealing block 308 to slowly seal the thin hole 305, so that the gas inside the connecting pipe 106 can be completely discharged.
