Description

Technical Field

[0001] This utility model relates to the field of water balance testing, specifically to a portable water balance testing device. Background Technology

[0002] Water balance test data is typically collected using existing metering equipment installed at the tested unit. However, in practice, the availability and accuracy of existing metering equipment often fail to meet testing requirements. Therefore, it is usually necessary to temporarily install water monitoring equipment at new test points, with clamp-on ultrasonic flow meters being the most common choice. Common clamp-on ultrasonic flow meters are mainly divided into portable and fixed types. Portable ultrasonic flow meters have built-in rechargeable batteries, and their continuous working time on a single charge is generally no more than 10 hours, primarily designed for temporary flow measurements in various situations. Fixed ultrasonic flow meters can continuously collect flow data, but require an external 220V AC power supply, placing higher demands on installation conditions and resulting in a longer installation time. The "General Rules for Water Balance Testing" (GB / T 12452-2022) stipulates that tests should be conducted over a stable and representative period, with continuous testing for at least 7 days, recording data at least once every 24 hours, and obtaining at least 8 test data points. Therefore, existing ultrasonic flow meters, whether portable ultrasonic flow meters with built-in rechargeable batteries or fixed ultrasonic flow meters powered by external mains electricity, all have certain limitations in actual testing and cannot fully meet the testing requirements.

Detailed Implementation

[0020] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0021] like Figures 1-5 As shown, a portable water balance testing device includes a portable carrying case 1 with a lid 7 to protect the equipment inside. Inside the carrying case 1 are mounting blocks on which a battery 8, a controller 6, a flow meter 5, and a wire storage mechanism 2 are mounted. The wire connecting the flow meter 5 and the controller 6 is stored in the wire storage mechanism 2. The battery 8 is electrically connected to the controller 6 via a wire. The controller 6 contains a wireless data transmission module. A locking device is provided on the wire storage mechanism 2 for locking the wire storage mechanism 2.

[0022] The controller 6 is equipped with a C51 microcontroller and features a display screen for showing measured data. The battery 8 is a separate, replaceable module. The flow meter 5 is an FTE-1600T series insertion-type electromagnetic flow meter. Dedicated plugs are provided for the wiring to the flow meter 5, battery 8, and controller 6 for easy assembly and disassembly. The flow meter 5 transmits the collected data to the controller 6, which then transmits the data in real-time to a remote server or monitoring center via a wireless data transmission module. This wireless data transmission module uses a 4G DTU-ZSD3400 wireless data transmission terminal.

[0023] This solution is used for long-term water balance testing. Water flow is collected by flow meter 5. The portable carrying case 1 provides space for the installation and use of large battery 8, solving the problem of short power supply time of existing portable flow meters 5. Furthermore, the entire device integrates flow meter 5, battery 8 and data communication into one unit, saving the manpower and material resources required for the installation of fixed flow meter 5. It can realize real-time online data transmission, improve the flexibility and efficiency of water balance testing, ensure the continuity and stability of test data, and thus improve the scientific nature of the entire water balance testing work.

[0024] In this embodiment, the mounting block is provided with a wire channel 4 for wiring. The wires between the battery 8 and the controller 6, and the wires between the flow meter 5 and the controller 6 are arranged in the wire channel 4. This facilitates the routing of wires within the carrying case 1, making the layout of the equipment more reasonable.

[0025] In this embodiment, the battery 8, controller 6, and flow meter 5 are respectively installed in the mounting slots 3 on the mounting block, and the wire storage mechanism 2 is installed in the storage slot on the mounting block. Each device and module is independently housed within the carrying case 1, facilitating easy assembly. During operation, only the carrying case 1 needs to be carried to the testing location. When the battery 8 is low on power, it can be disassembled and replaced.

[0026] In this embodiment, the wire storage mechanism 2 includes a base 9 installed at the bottom of the storage slot. A hollow support shaft 10 is fixedly installed at the upper end of the base 9, and the support shaft 10 is perpendicular to the base 9. A drum 11 is installed on the support shaft 10 through a bearing. An upper baffle 13 and a lower baffle 12 are respectively installed at the upper and lower ends of the drum 11. A gap is provided between the lower baffle 12 and the base 9. A locking device is installed on the upper baffle 13.

[0027] The locking device includes a small-diameter end 16 and a locking cover 14 fixedly connected to the support shaft 10. The small-diameter end 16 extends out of the upper end of the upper baffle 13. The side of the small-diameter end 16 is provided with a first axial protrusion 18. The inner wall of the locking cover 14 is provided with a first groove 19 that cooperates with the first protrusion 18. The first protrusion 18 and the first groove 19 are inserted and slidably engaged.

[0028] The outer wall of the locking cover 14 is provided with a second convex strip 15 along the axial direction, and the upper baffle 13 is provided with a second groove that cooperates with the second convex strip 15. The second groove and the second convex strip 15 are inserted into each other.

[0029] In this embodiment, the flow meter 5 is equipped with a long wire, which makes it convenient for the flow meter 5 to collect water flow data at a distance from the carrying case 1. It can adapt to a variety of testing environments. The long wire is stored by the wire storage mechanism 2, which is convenient to operate and avoids the long wire from being messy in the carrying case 1 and affecting the operation.

[0030] When the wire is wound on the drum 11, a conductive slip ring 20 is provided in the middle of the support shaft 10. One end of the conductive slip ring is connected to the wire on the drum 11, and the other end is connected to the wire of the controller 6. The drum 11 has a through hole for easy wire routing, and the other end of the wire is led out from the bottom of the base 9.

[0031] The upper baffle 13 is equipped with a handle 17 for easy rotation of the drum 11. During the wire winding process, simply rotate the drum 11 using the handle 17. During rotation, the wire is collected on the drum 11. A gap is designed between the drum 11 and the storage groove to avoid interfering with the wire collection. After the wire is collected, the locking cover 14 is placed on the upper end of the small diameter end 16, so that the first protrusion 18 is engaged in the first groove 19 and the second protrusion 15 is engaged in the second groove, thereby fixing the drum 11 and preventing it from loosening during transportation. If it is necessary to unwind the wire, simply remove the locking cover 14.
