Description

Technical Field

[0001] This utility model relates to the field of flow detection technology, specifically a flow detection device with an early warning function. Background Technology

[0002] As an institution specifically responsible for water resources management and technical work, the Water Resources Center undertakes responsibilities related to water resources management, conservation, and protection. Among these responsibilities, supervising water-taking entities is one of the key tasks of the Water Resources Center. The Water Resources Center verifies and monitors the water intake flow of water utilities to ensure that their water intake activities comply with approval regulations and water usage purposes. At the same time, the Water Resources Center also conducts comprehensive supervision of water utilities' water intake facilities, metering methods, implementation of planned water use, and water resources tax payments to ensure the sustainable use of water resources and the protection of the ecological environment. Currently, in the process of supervising water utilities, the Water Resources Center usually installs ultrasonic flow meters in the water intake pipelines of water utilities to monitor the water intake flow.

[0003] However, the ultrasonic flow meters currently used by the Water Resources Center to monitor water companies lack effective early warning functions. During use, these flow meters are easily altered by unscrupulous individuals, leading to discrepancies between the flow data seen by the Water Resources Center's back-end personnel and the actual data, which in turn causes certain economic losses to relevant departments. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a flow detection device with an early warning function. This solves the problem that the ultrasonic flow meters currently used by water resource centers to monitor water companies lack effective early warning functions, making them susceptible to manipulation of preset parameters by unscrupulous individuals. This results in discrepancies between the flow data seen by the water resource center's back-end personnel and the actual data, causing economic losses to relevant departments.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a flow detection device with an early warning function, including a water intake pipe. A protective shell is fixedly installed on the top of the water intake pipe. An ultrasonic flow meter main unit is fixedly installed at the right end of the bottom of the inner cavity of the protective shell. Transmission cables are fixedly installed at both ends of the right side of the ultrasonic flow meter main unit. An ultrasonic sensor is fixedly installed at the lower end of the transmission cables. A fixing cover is fixedly connected to the left end of the inner cavity of the protective shell. A wireless communication module and a central processing unit are fixedly installed in the inner cavity of the fixing cover from top to bottom. The wireless communication module is used for signal transmission with the backend. An AD converter is fixedly installed on the top of the central processing unit. A magnetic switch is fixedly installed on the left end of the top of the fixing cover. A protective cover is movably connected between the right ends of the two sides of the protective shell through a bearing. A magnetic block is fixedly connected to the upper end of the protective cover.

[0007] As a preferred embodiment, a pin hole is provided at the upper end of the left side of the inner cavity of the protective shell, and the number of pin holes is two.

[0008] As a preferred embodiment, a U-shaped rod is slidably connected between the two ends of the top of the protective cover, and a limit lever is fixedly connected to both ends of the bottom of the U-shaped rod. A fixing plate is fixedly connected to both ends of the U-shaped rod, and a support spring is fixedly connected between the bottom of the fixing plate and the top of the protective cover.

[0009] As a preferred embodiment, both ends of the right side of the protective shell are fixedly connected to a cable tray, the inner cavity of the cable tray is fitted onto the surface of the transmission cable, a rubber sealing ring is fixedly connected to the inner cavity of the cable tray, the surface of the rubber sealing ring is fitted onto the surface of the transmission cable, and a heat shrink tubing is fitted between the right end of the outer surface of the cable tray and the surface of the transmission cable.

[0010] As a preferred embodiment, flanges are fixedly connected to both sides of the water intake pipe, and rubber sealing gaskets are fixedly installed on the surface of the flanges.

[0011] As a preferred embodiment, a display screen is fixedly installed on the top of the ultrasonic flow meter main unit, and control buttons are fixedly installed on the top of the ultrasonic flow meter main unit and in front of the display screen.

[0012] As a preferred embodiment, the ultrasonic sensor is threadedly mounted on the middle of the water intake pipe.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] 1. This utility model, through the installation of a water intake pipe, can be connected to the water inlet pipe of a water company. Using an ultrasonic flow meter main unit, transmission cables, and ultrasonic sensors, it can effectively monitor the flow rate of water passing through the intake pipe and transmit data to the water resource center's backend via a wireless communication module. This allows backend personnel to remotely monitor and supervise the system. Furthermore, the central processing unit can process and analyze the preset parameters of the ultrasonic flow meter main unit. When any personnel change the preset parameters, the central processing unit can promptly process and analyze the changed parameters and send an early warning to the water resource center's backend via the wireless communication module, enabling backend personnel to promptly detect and address the issue. The system detects and takes appropriate action. The protective casing and cover provide safety protection for the ultrasonic flow meter main unit, central processing unit, and wireless communication module. During routine maintenance, personnel from the water resources center open and close the protective cover and casing, separating and then reconnecting the magnetic block and magnetic switch. This allows the internal contacts of the magnetic switch to open and close. The central processing unit records the opening and closing times of the magnetic switch. If no one opens the protective cover during the next maintenance period, the central processing unit sends a warning to the water resources center's backend via the wireless communication module, enabling timely maintenance and ensuring stable flow detection operations.

[0015] 2. This utility model, through the setting of pin holes, U-shaped rods, fixing discs, support springs, and limiting rods, allows the limiting rods to be inserted into the pin holes during the process of personnel closing the protective cover and protective shell, thereby limiting the distance between the protective cover and the protective shell and preventing them from opening during non-human operation. The setting of cable routing pipes, rubber sealing rings, and heat shrink tubing not only allows for cable routing but also effectively improves the sealing performance between the transmission cable and the protective shell, effectively preventing water from entering the interior of the protective shell along the gaps around the transmission cable. The setting of flanges and rubber sealing gaskets facilitates the installation and fixing of the water intake pipe and the water company's inlet pipe using bolts, while also effectively improving the sealing performance of the connection installation.

[0025] Please see Figure 1-4This utility model provides a technical solution: a flow detection device with early warning function, including a water intake pipe 8, a protective shell 2 fixedly installed on the top of the water intake pipe 8, an ultrasonic flow meter host 1 fixedly installed at the bottom right end of the inner cavity of the protective shell 2, transmission cables 6 fixedly installed at both ends of the right side of the ultrasonic flow meter host 1, an ultrasonic sensor 7 fixedly installed at the lower end of the transmission cables 6, a fixed cover 12 fixedly connected to the left end of the inner cavity of the protective shell 2, a wireless communication module 18 and a central processing unit 17 fixedly installed from top to bottom in the inner cavity of the fixed cover 12, the wireless communication module 18 is used for signal transmission with the background, an AD converter 22 is fixedly installed on the top of the central processing unit 17, a magnetic switch 13 is fixedly installed on the left end of the top of the fixed cover 12, and a protective cover 5 is movably connected between the right ends of both sides of the protective shell 2 through a bearing, and a magnetic block 4 is fixedly connected to the upper end of the protective cover 5.

[0026] In use, the water intake pipe 8 can be connected to the water inlet pipe of the water company. Through the ultrasonic flow meter host 1, transmission cable 6, and ultrasonic sensor 7, the flow rate of the water flowing through the water intake pipe 8 can be effectively monitored. Simultaneously, the data can be transmitted to the back-end of the water resources center via the wireless communication module 18, allowing back-end personnel to remotely monitor and supervise the process. Furthermore, the central processing unit 17 can process and analyze the preset parameters of the ultrasonic flow meter host 1. When any personnel change the preset parameters of the ultrasonic flow meter host 1, the central processing unit 17 can promptly process and analyze the changed parameters and send an early warning to the back-end of the water resources center via the wireless communication module 18, enabling back-end personnel to promptly detect and take appropriate action. The protective shell 2 and protective cover 5 provide safety protection for the ultrasonic flow meter main unit 1, central processing unit 17, and wireless communication module 18. During regular maintenance, personnel from the water resources center will open and close the protective cover 5 and protective shell 2. This process will cause the magnetic block 4 and magnetic control switch 13 to separate and then re-engage, allowing the contacts inside the magnetic control switch 13 to open and close again. At this time, the AD converter 22 can convert the electrical signal when the magnetic control switch 13 is turned on into a digital signal, which is then processed and analyzed by the central processing unit 17. If no one opens the protective cover 5 during the next maintenance period, the central processing unit 17 will send an early warning to the water resources center's backend via the wireless communication module 18, so that the backend personnel can perform maintenance work in a timely manner and ensure that the flow detection operation can be carried out stably for a long time.

[0027] like Figure 1-4As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, a pin hole 11 is provided at the upper end of the left side of the inner cavity of the protective shell 2. There are two pin holes 11. A U-shaped rod 3 is slidably connected between the two ends of the top of the protective cover 5. Limiting rods 21 are fixedly connected to both ends of the bottom of the U-shaped rod 3. Fixing plates 20 are fixedly connected to both ends of the U-shaped rod 3. A supporting spring 19 is fixedly connected between the bottom of the fixing plate 20 and the top of the protective cover 5. Cable guide tubes 15 are fixedly connected to both ends of the right side of the protective shell 2. The inner cavity of the cable guide tube 15 is sleeved on the surface of the transmission cable 6. On the surface, a rubber sealing ring 16 is fixedly connected to the inner cavity of the cable 15, and the surface of the rubber sealing ring 16 is sleeved on the surface of the transmission cable 6. A heat shrink tubing 14 is sleeved between the right end of the outer surface of the cable 15 and the surface of the transmission cable 6. Flanges 9 are fixedly connected to both sides of the water intake pipe 8, and rubber sealing gaskets 10 are fixedly installed on the surface of the flanges 9. A display screen is fixedly installed on the top of the ultrasonic flow meter main unit 1, and control buttons are fixedly installed on the top of the ultrasonic flow meter main unit 1 and in front of the display screen. The surface of the ultrasonic sensor 7 is threadedly installed in the middle of the water intake pipe 8.

[0028] Analysis of the above structure shows that, through the setting of pin hole 11, U-shaped rod 3, fixing plate 20, support spring 19 and limiting rod 21, during the process of personnel closing the protective cover 5 and the protective shell 2, the limiting rod 21 can be inserted into the pin hole 11, thereby limiting the connection between the protective cover 5 and the protective shell 2 and preventing the protective cover 5 and the protective shell 2 from opening during non-human operation. Through the setting of cable tray 15, rubber sealing ring 16 and heat shrink tubing 14, the transmission cable 6 can be routed, while effectively improving the sealing performance of the contact between the transmission cable 6 and the protective shell 2, effectively preventing water from entering the interior of the protective shell 2 along the gaps around the transmission cable 6. Through the setting of flange 9 and rubber sealing gasket 10, it is convenient for personnel to use bolts to install and fix the water intake pipe 8 and the water company's inlet pipe, while effectively improving the sealing performance of the docking installation.
