Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and specifically discloses a water pump with flow detection function. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy, and is used to transport liquid-gas mixtures and liquids containing suspended solids. Technical parameters of water pump performance include flow rate, suction head, discharge head, shaft power, water power, and efficiency. These technical parameters allow for the calculation of the pump's flow rate during operation. However, in actual operation, leaks can occur due to sealing issues at the connection points between the pump's surface pipes and the external water pipes, leading to water waste. Furthermore, leaks can cause discrepancies between the calculated flow rate and the actual output flow, affecting flow rate detection.

[0003] Chinese patent CN219570306U discloses a water pump with flow detection function. This device can make the sealing strip and the sealing groove fit together through the pushing mechanism to achieve a secondary sealing effect, improve the connection between the inner connecting pipe and the outer water pipe, and under the action of the floating block, sensing block and receiving block, it can remind the staff of the leakage and then repair it. By reducing the probability of leakage, the accuracy between the calculated flow rate and the actual water output is improved.

[0004] However, the above-mentioned device has the following problems:

[0005] The secondary sealing is achieved by manually operating the sealing plate through a threaded rod, which is cumbersome to adjust.

[0006] The mechanical sensing block is brought into contact with the receiving block by the buoyancy of the floating block. The response speed is limited by the liquid accumulation time and is easily affected by mechanical wear.

[0007] Relying on theoretical calculations of flow rate does not address the issue of flow rate deviation caused by actual leakage.

[0008] It relies entirely on local mechanical structures, lacks data interaction and remote control functions, and leak alarms depend on indicator lights, lacking an automatic protection mechanism. Utility Model Content

[0009] This invention proposes a water pump with flow detection function, which enables rapid installation and sealing, reduces manual adjustment steps, has high electronic sensor sensitivity and can detect minute leaks, and the data is uploaded to the cloud platform control center through a wireless communication module. If the deviation from the theoretical value exceeds the threshold, the system automatically adjusts the water pump power to calibrate the output.

[0010] This utility model is implemented as follows: a water pump with flow detection function includes:

[0011] The pump body and the base are fixedly connected to the bottom of the pump body. The outlet end of the pump body is fixedly connected to an inner connecting pipe. The other end of the inner connecting pipe is connected to an outer connecting pipe through a flange. The flange includes a first flange plate and a second flange plate.

[0012] A sealing module, comprising an annular sealing groove formed inside a first flange plate, and a sealing ring fixedly connected to the outer wall of a second flange plate and matching the sealing groove. A magnetic ring is fixedly connected inside the sealing groove, and a sealing ring that abuts against the magnetic ring is also embedded inside the sealing groove.

[0013] A leakage detection mechanism includes a liquid collection tank located directly below a flange, with a humidity sensor and a pressure sensor installed at the bottom of the tank.

[0014] As a preferred embodiment of the water pump with flow detection function according to this utility model, the leakage monitoring mechanism further includes an ultrasonic flow meter disposed inside the inner connecting pipe.

[0015] As a preferred embodiment of the present invention, the water pump with flow detection function further includes a water pump controller and an audible and visual alarm installed on the top of the water pump body. The water pump controller is equipped with a wireless communication module and is connected to the cloud platform via the wireless communication module. The humidity sensor, pressure sensor and audible and visual alarm are all electrically connected to the water pump controller.

[0016] As a preferred embodiment of the water pump with flow detection function of this utility model, inclined guide plates are fixedly connected to both the left and right ends of the inner wall of the liquid collection tank.

[0017] As a preferred embodiment of the water pump with flow detection function according to this utility model, the bottom of the liquid collection tank is connected to a drain pipe, and a drain valve is provided on the outer wall of the drain pipe.

[0018] As a preferred embodiment of the water pump with flow detection function of this utility model, a column is fixedly connected to the upper end face of the base, a rotating cylinder is rotatably connected to the outer wall of the column, a connecting rod is fixedly connected to the outer wall of the rotating cylinder, and the liquid collection tank is fixedly connected to the other end of the connecting rod.

[0020] The beneficial effects of this utility model are:

[0021] When connecting the inner and outer connecting pipes, the flange is quickly positioned and installed by inserting the sealing ring into the sealing groove. The magnetic ring attracts the sealing ring, and the sealing ring squeezes the sealing ring to seal, resulting in a good sealing effect. Finally, the first and second flange plates are fixed with bolts to achieve quick installation and sealing, reducing manual adjustment steps.

[0022] If a leak occurs, the liquid enters the collection tank and quickly reaches the sensor detection area along the guide plate. The humidity sensor and pressure sensor detect the signal simultaneously. The electronic sensor has high sensitivity and can detect even minor leaks.

[0023] Simultaneously, the audible and visual alarm is triggered to prevent the leakage from escalating and reduce safety risks. At the same time, the water pump controller shuts down the water pump, and the ultrasonic flow meter monitors the flow rate in real time. The data is uploaded to the cloud platform control center via a wireless communication module. If the deviation from the theoretical value exceeds the threshold, the system automatically adjusts the water pump power to calibrate the output. Attached Figure Description
