Description

Technical Field

[0001] This utility model relates to the field of water balance testing technology, and in particular to a water balance testing device with a protective structure. Background Technology

[0002] In water balance testing, flow meters, as core metering components, are susceptible to impurities in the water flow, which can affect their accuracy or shorten their lifespan. Furthermore, traditional equipment lacks effective methods for detecting water leakage, making it difficult to detect leaks promptly and potentially leading to equipment failure and safety risks. Additionally, conventional equipment maintenance requires complete disassembly to clean impurities, which is cumbersome and inefficient. Moreover, observing flow data often necessitates disassembling the protective structure, compromising ease of use. These issues result in shortcomings in the stability, safety, and ease of maintenance of existing water balance testing equipment, making it difficult to meet the demands of efficient and reliable testing. Therefore, there is an urgent need for a water balance testing device with protective, early warning, and convenient maintenance functions to address these pain points.

[0003] Existing technology authorization announcement number CN208998876U discloses a water balance testing device with a protective structure, including a protective cover, a flow meter, a fixing device, and a limiting block. A fixed pipe is fixedly installed at the bottom of the flow meter, and connecting blocks are welded to both sides of the top of the fixed pipe. The protective cover is installed on the top of the connecting blocks, and a connecting pipe is fixedly installed on the right side of the fixed pipe via the fixing device. This utility model combines the structure of existing traditional water balance testing equipment, considering the need to improve overall protective performance and effectively reduce clogging. Furthermore, it features a simple structure, convenient operation, and improved overall practicality.

[0004] However, this device requires operators to open the protective cover to view the flow meter data during use, and cleaning the filter installed inside the pipeline requires removing the entire device from the pipeline, making it inconvenient and reducing work efficiency. Furthermore, the lack of leakage monitoring measures hinders timely detection of equipment damage, increasing operational risks. Therefore, we propose a water balance testing device with a protective structure. This solves the problems of inconvenient use and maintenance, as well as the lack of leakage monitoring measures, improving the ease of use and maintenance. Simultaneously, it can promptly alert operators to equipment leaks, enabling timely repair services, preventing greater economic losses, and ensuring the safe use of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a water balance testing device with a protective structure, which solves the problems of inconvenience in use and maintenance and lack of seepage monitoring measures mentioned in the background art.

It also includes a filter tube, which has a filter cartridge installed inside. The filter cartridge has an opening on the side away from the flow meter that can cover the cross-section of the test tube.

[0007] The filter tube is fixedly provided with a first flange joint at the top end, the inner wall of the first flange joint is provided with a groove, the groove is provided with a slot, and the bottom side of the outer edge of the top end of the filter tube is provided with a locking block that matches and fits into the slot.

[0008] The first flange joint has a cap fixed to its top with bolts, and a seepage-proof gasket is fitted between the cap and the first flange joint. The filter pipe has a drain outlet at its bottom, and an end cap is threaded to the bottom of the drain outlet. A sealing gasket is installed between the end cap and the drain outlet.

[0009] The test tube is fixedly provided with a second flange joint at one end near the filter cartridge, and a third flange joint at the other end.

[0010] The filter cartridge is made of stainless steel. The filter tube is located between the second flange joint and the flow meter. The inner diameter of the filter tube is the same as the inner diameter of the test tube. The filter tube and the test tube are perpendicular to each other and connected to each other.

[0011] The protective cover has a viewing window fixedly installed at its top, an internal thread on the inner wall of its lower end, and an external thread that matches and screws onto the top of the mounting base.

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The first embodiment of this application is as follows: Please see Figure 1 - Figure 3 This embodiment of a water balance testing device with a protective structure includes a test tube 1. A mounting base 2 is fixedly installed on the outside of the test tube 1. A flow meter 3 is fixedly installed on the top of the mounting base 2. A protective cover 4 is detachably fixed to the outside of the flow meter 3. An alarm 5 is fixedly installed on the outer wall of the protective cover 4. The alarm 5 is electrically connected to a water immersion sensor 6 via a wire. The water immersion sensor 6 is fixedly installed on the inner wall of the protective cover 4. A viewing window 20 is fixedly installed on the top of the protective cover 4. An internal thread 21 is provided on the inner wall of the lower end of the protective cover 4. An external thread 22 that matches and screws into the internal thread 21 is fixedly installed on the top of the mounting base 2. A second flange joint 18 is fixedly installed at one end of the test tube 1 near the filter cartridge 8, and a third flange joint 19 is fixedly installed at the other end.

[0018] With the above scheme, when the equipment is working, water flows through the test pipe 1, enters through the second flange joint 18, and exits through the third flange joint 19. The flow meter 3, fixed to the mounting base 2, monitors the water flow parameters in real time. The protective cover 4 is screwed to the external thread 22 of the mounting base 2 via the internal thread 21, forming a closed protective space to protect the flow meter 3 from external impacts or debris. Personnel can observe the status of the flow meter 3 through the viewing window 20. If water leakage occurs inside the protective cover 4, the water immersion sensor 6 on the inner wall triggers a signal, which is transmitted to the alarm 5 via a wire. The alarm 5 then activates, prompting maintenance, ensuring stable operation of the equipment and reducing the risk of equipment use.

[0019] The second embodiment of this application is as follows: Please see Figure 2 - Figure 4 Based on the first embodiment, this embodiment of a water balance testing device with a protective structure further includes a filter tube 7, inside which a filter cartridge 8 is fitted. The filter cartridge 8 is made of stainless steel. The filter tube 7 is positioned between the second flange joint 18 and the flow meter 3. The inner diameter of the filter tube 7 is the same as the inner diameter of the test tube 1. The filter tube 7 and the test tube 1 are perpendicular to each other and interconnected. The filter cartridge 8 has an opening 23 on the side away from the flow meter 3 that can cover the cross-section of the test tube 1. A first flange joint 9 is fixedly installed at the top of the filter tube 7. A groove 10 is opened on the inner wall of the first flange joint 9. A slot 11 is opened on the groove 10. A locking block 12 that matches and fits into the slot 11 is provided on the bottom side of the outer edge of the top of the filter tube 8. A cover 13 is fixedly installed at the top of the first flange joint 9 by bolts. An anti-seepage gasket 14 is installed between the cover 13 and the first flange joint 9. A drain port 15 is opened at the bottom of the filter tube 7. An end cap 16 is threadedly connected to the bottom of the drain port 15. A sealing gasket 17 is installed between the end cap 16 and the drain port 15.

[0020] With the addition of the filtration structure, water flows through the second flange joint 18 into the filter pipe 7. The stainless steel filter cartridge 8 covers the cross-section of the test pipe 1 through the opening 23, filtering the water and intercepting impurities. The filter cartridge 8 is fixed by the locking block 12 and the locking slot 11 of the first flange joint 9, preventing the filter cartridge 8 from rotating or shifting. The cover 13 is bolted to the top of the first flange joint 9, and a leak-proof gasket 14 is used to prevent leakage at the interface. The filtered water flows into the test pipe 1, where the flow meter 3 detects the parameters. Accumulated impurities can be removed by opening the cover 13 to clean or replace the filter cartridge 8. In addition, the end cap 16 of the drain port 15 can be opened periodically to discharge some of the impurities deposited at the bottom of the filter pipe 7. This filtration structure is simple and convenient to use, requiring no disassembly of the entire equipment, reducing the burden on operators and improving maintenance efficiency.

[0021] Working principle: First, connect the second flange connector 18 to the pipe in the direction of incoming water, and the third flange connector 19 to the pipe in the direction of outgoing water. After checking the protective cover, sealing cover 13, and end cap 16, testing can begin. The data changes of the flow meter 3 can be observed in real time through the protective cover 4 with a viewing window 20, without needing to remove the protective cover, making it more convenient to use. During the use of the flow meter 3, the alarm 5 installed on one side of the protective cover, in conjunction with the water immersion sensor 6 installed on its inner wall, detects water seepage inside the protective cover 4. The water immersion sensor 6 detects the physical or chemical changes caused by moisture, converts the signal into an electrical signal, and outputs it through the processing module. The alarm 5 receives the signal and triggers audible and visual alarm actions, thereby monitoring and warning of water seepage in the equipment, reminding staff to repair or replace the equipment in a timely manner, and reducing the risk of use. By installing a filter cartridge 8 in the test tube 1 between the inlet and the flow meter 3, impurities in the water flow can be filtered, thus improving the service life of the equipment. The filtered impurities fall into the filter cartridge 8, and the filter cartridge 8 can be removed by opening the cover 13. The equipment can be cleaned and maintained without disassembling the entire device, thereby improving work efficiency.

[0022] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
