[0002] Air conditioning chilled water pipelines are widely arranged on board ships. The amount of air conditioning chilled water is closely related to the cooling effect of the air conditioning fan. Since the air conditioning cooling water pipelines are long and tortuous, the flow resistance at the end of the pipeline is large. The end-user chilled water amount cannot be accurately measured, which makes it difficult to regulate the cooling capacity. When the end-user cooling effect is poor, it will become extremely troublesome to troubleshoot the cause of the equipment and system pipelines. At present, when measuring pipeline water volume, most of the methods are to install a branch pipe on the pipeline, connect the end of the branch pipe to a gear flowmeter, measure the branch pipe flow with the flowmeter, and obtain the functional relationship between the branch pipe flow and the main pipe flow through experiments.

[0003] When installing the gear flowmeter with the branch pipe, multiple connecting bolts are required to connect to the flange of the gear flowmeter.

[0038] In the further preferable embodiment of the present application, the connecting mechanism comprises: a fixed block 14 arranged on one side of the gear flowmeter body 3; a connecting cylinder 15 rotatably installed on the fixed block 14; a sliding rod 16 slidably installed on the connecting cylinder 15, one end of the sliding rod 16 being fixedly connected with the connecting bolt 6; a set of driven gears 17 fixedly sleeved on the rotating rod 8 and the connecting cylinder 15, respectively, one set of the driven gears 17 being engaged with each other; a connecting frame 18 fixedly installed on the top of the fixed block 14, a gear ring 19 being rotatably installed on the connecting frame 18, the gear ring 19 being engaged with the driven gear 17 on the connecting cylinder 15.

[0039] In the embodiment, in use, first, the rotating lever 8 and the one-way screw rod 9 are driven to rotate by rotating the rectangular seat 12, and then the sliding block 10 and the annular barrel 11 are moved, when the rotating lever 8 rotates, the driven gear 17 on the rotating lever 8 drives the driven gear 17 on the connecting barrel 15 to rotate, and then the connecting barrel 15 rotates synchronously with the rotating lever 8, when the driven gear 17 rotates, the gear ring 19 is driven to rotate, and then the plurality of connecting barrels 15 rotate synchronously, when the annular barrel 11 drives the connecting bolt 6 to contact the nut 5, the sliding lever 16 rotates and tightens the connecting bolt 6 on the nut 5, because the gear ring 19 is engaged with the plurality of driven gears 17, so that the plurality of connecting bolts 6 can be driven to rotate simultaneously, the fast and synchronous installation and tightening process is realized, through the design of the connecting mechanism, the fast and synchronous rotation and tightening of the plurality of connecting bolts 6 are realized, which not only improves the installation efficiency, but also guarantees the synchronization and consistency of the installation, the cooperation of the driven gear 17 and the gear ring 19 makes the transmission process more stable and reliable, even in the case of large load, the stability and accuracy of the transmission can be guaranteed, compared with the traditional manual tightening of the connecting bolt 6 one by one, the connecting mechanism of the present application only needs to rotate the gear ring 19 to complete the synchronous rotation and tightening of the plurality of connecting bolts 6, greatly simplifying the operation steps.

[0040] In the further preferred embodiment of the application, one side of the connecting frame 18 is fixedly provided with a Z-shaped block 20, and a screw rod 21 is threadedly installed on the Z-shaped block 20. A threaded hole is formed in the top of the sliding lever 16, and the threaded hole is matched with the screw rod 21.

[0041] In the embodiment, when it is necessary to adjust the position of the sliding lever 16, the user first removes the screw rod 21 from the Z-shaped block 20, and then moves the sliding lever 16 to the desired position. After the sliding lever 16 is moved to the specified position, the screw rod 21 is threadedly installed on the Z-shaped block 20, and the thread of the screw rod 21 is screwed into the threaded hole of the sliding lever 16, so as to fix the position of the sliding lever 16. By designing the combination of the Z-shaped block 20, the screw rod 21 and the sliding lever 16, the connecting bolt 6 can be ensured to be stably positioned at the specified position after installation, and then the connecting bolt 6 is prevented from loosening.

[0042] In the further preferred embodiment of the application, the inner cavity of the connecting barrel 15 and the sliding lever 16 are both rectangularly arranged, and the Z-shaped block 20 is located above the sliding lever 16.

[0043] In this embodiment, the slide rod 16 is designed to be rectangular in shape, matching the inner cavity of the connecting tube 15. This design ensures that the slide rod 16 can slide smoothly in the connecting tube 15 without generating unnecessary friction or resistance due to shape mismatch. In addition, the rectangular slide rod 16 also provides better guidance, making the connecting bolt 6 more precise and controllable during the sliding process. The rectangular design increases the contact area between the connecting tube 15 and the slide rod 16, thereby enhancing the stability of the entire structure. At the same time, the slide rod 16 can slide smoothly in the connecting tube 15, avoiding friction or resistance caused by shape mismatch. At the same time, the connecting tube 15 rotates to drive the slide rod 16 to slide at the same time, ensuring that the slide rod 16 will not slip in the connecting tube 15. The rectangular slide rod 16 provides better guidance, making the sliding process more precise and controllable.

[0044] In a further preferred embodiment of the present invention, the protective mechanism includes: a positioning rod 22 fixedly mounted on one side of the flange 4 and the gear flowmeter body 3 respectively; a protective cover 23 slidably arranged on the positioning rod 22, and the protective cover 23 is arranged on the mounting mechanism, and the protective cover 23 consists of two arc-shaped shells.

[0045] In this embodiment, after the connecting bolts 6 are installed, the protective cover 23 is placed on the mounting mechanism, and then the protective cover 23 is slid to one side so that the protective cover 23 is slidably connected to the positioning rod 22, and then the position of the protective cover 23 is positioned to ensure that it does not fall from the gear flowmeter body 3. By providing a closed protective space for the mounting mechanism, the protective cover 23 can effectively prevent the external environment from interfering with or damaging the mounting mechanism, thereby improving the stability of the equipment. The protective cover 23 can reduce the erosion of impurities such as dust and moisture on the mounting mechanism, thereby reducing the equipment failure rate and extending the service life.

[0046] In a further preferred embodiment of the present invention, a group of threaded rods 24 are rotatably installed on one side of the protective cover 23, and a group of the threaded rods 24 are respectively located on two arc-shaped shells. A threaded barrel 25 is threadedly sleeved on each of the threaded rods 24, and the threaded barrel 25 located above is slidably connected to the slot on one side of the positioning rod 22, and a handle 26 is fixedly installed on one end of the threaded rod 24 located above.

[0047] In the embodiment, when the protective cover 23 needs to be fixed, the user can rotate the handle 26 to rotate the threaded rod 24, and since the threaded cylinder 25 is in threaded cooperation with the threaded rod 24, the threaded cylinder 25 will move to one side along the threaded rod 24 until it is in sliding connection with the clamping groove on the positioning rod 22 and is clamped, so that the protective cover 23 is stably fixed at the required position to provide protection for the installation mechanism. When the protective cover 23 needs to be moved or loosened, the user only needs to rotate the handle 26 in the opposite direction to rotate the threaded rod 24 in the opposite direction, at this time, the threaded cylinder 25 will move to one side along the threaded rod 24 and be disconnected with the clamping groove, and then the protective cover 23 can be disassembled. Through the cooperation of the threaded rod 24, the threaded cylinder 25 and the clamping groove, the stable fixation of the protective cover 23 on the positioning rod 22 is realized, and the shaking or falling phenomenon caused by unstable fixation is avoided. The design of the handle 26 enables the user to conveniently rotate the threaded rod 24, so as to easily adjust the position of the threaded cylinder 25 on the threaded rod 24, and realize the quick fixation and loosening of the protective cover 23.

[0048] In the further preferred embodiment of the present application, the inner walls of the two arc-shaped housings are each fixedly provided with a clamping seat 27, and a clamping block 28 is slidingly installed on the two clamping seats 27. The clamping block 28 is fixedly connected with the threaded cylinder 25 below. A connecting gear 29 is fixedly sleeved on each of the two threaded rods 24, and the two connecting gears 29 are in meshing engagement.

[0049] In the embodiment, when the two arc-shaped housings need to be connected, the handle 26 is first rotated to rotate the upper threaded rod 24, and through the arrangement of the connecting gear 29, the two threaded rods 24 are simultaneously driven to rotate. When the upper threaded cylinder 25 slides to the right and is in sliding connection with the clamping groove on the positioning rod 22, the lower threaded cylinder 25 slides to the left, thereby driving the clamping block 28 to slide and enabling the clamping block 28 to slide and clamp into the clamping seat 27, so as to connect the two arc-shaped housings and ensure that they are stably fixed on the gear flowmeter body 3. Through the cooperation of the clamping seat 27 and the clamping block 28 and the transmission of the connecting gear 29, the structural stability of the protective cover 23 is further enhanced, so that it can better adapt to different installation environments and requirements. Since the two threaded rods 24 are each fixedly sleeved with the meshing connecting gears 29, when one of the threaded rods 24 is rotated, the other threaded rod 24 will also be synchronously rotated, thereby realizing the synchronous positioning function of the protective cover 23 and improving the operation efficiency.

[0050] In the further preferred embodiment of the present application, a guide rod 30 is fixedly installed on one side of the inner wall of the protective cover 23, and a guide block 31 is slidingly sleeved on the guide rod 30. One side of the guide block 31 is fixedly connected with one side of the threaded cylinder 25.

[0051] In this embodiment, the design of the guide rod 30 ensures that the guide block 31 can slide stably along it, thereby further enhancing the structural stability and adjustment function of the protective cover 23. Through the cooperation of the guide rod 30 and the guide block 31, the structural stability of the protective cover 23 is further enhanced, and the stability and accuracy of the threaded barrel 25 during movement are also ensured, thereby improving the adjustment accuracy and reliability of the protective cover 23.

[0052] The present invention also provides a method for using a gear flowmeter, comprising the following steps:

[0053] When the rectangular seat 12 is rotated, the rotating rod 8 and the one-way screw 9 can be driven to rotate through the transmission action of the bevel gear 13, thereby driving the slider 10 and the annular cylinder 11 to move. When the rotating rod 8 rotates, the connecting mechanism is driven to operate at the same time, so that the driven gear 17 rotates to drive the connecting cylinder 15 and the rotating rod 8 to rotate synchronously. At the same time, the driven gear 17 on the connecting cylinder 15 simultaneously drives the gear ring 19 to rotate, thereby causing multiple connecting cylinders 15 to rotate synchronously, so that the connecting mechanism drives the connecting bolts 6 on the annular cylinder 11 to rotate. When the annular cylinder 11 drives the connecting bolts 6 to contact the nuts 5, the rectangular seat 12 is continued to be rotated. Since the connecting mechanism and the rotating rod 8 rotate synchronously, multiple connecting bolts 6 are driven to rotate and tightened on the nuts 5 at the same time. The whole installation process is fast, stable and controllable.

[0054] Step 2: After installing the connecting bolts 6, place the protective cover 23 on the mounting mechanism, then slide the protective cover 23 to one side so that the protective cover 23 is slidably connected to the positioning rod 22, thereby positioning the protective cover 23 to ensure that it does not fall off the gear flowmeter body 3;

[0055] Step 3: Then turn the handle 26 to rotate the upper threaded rod 24. Through the setting of the connecting gear 29, the two threaded rods 24 are driven to rotate at the same time. When the upper threaded cylinder 25 slides to the right and slides into the slot on the positioning rod 22, the lower threaded cylinder 25 slides to the left, thereby driving the block 28 to slide, so that the block 28 slides into the card seat 27, connecting the two arc-shaped shells to ensure that they are firmly on the gear flowmeter body 3;

[0056] Step 4: After the fluid enters the connecting pipe through the branch pipe 2, it is discharged into the filter cartridge 32. Inside the filter cartridge 32, the fluid is filtered by multiple V-shaped filter screens 35 to remove impurities. The filtered fluid then enters the flow meter body 3 for measurement. Since the filter screen 35 is slidably connected to the arc-shaped clamping plate 33, when the filter screen 35 is blocked or needs to be cleaned, the user can easily remove it from the filter cartridge 32 for replacement or cleaning.

[0057] In order to further improve the use effect of the device, in addition to the above-mentioned scheme, the present scheme also has the following embodiments:

[0058] In another embodiment of the application, the gear flowmeter body 3 further comprises a filter cartridge 32 and a connecting pipe, the connecting pipe is fixedly connected with the flange 4, the filter cartridge 32 is fixedly connected with the connecting pipe, the filter cartridge 32 is located on one side of the main body of the gear flowmeter body 3, a plurality of arc clamping plates 33 are fixedly installed on the inner wall bottom of the filter cartridge 32, a plurality of filter screens 35 for filtering impurities in the branch pipe 2 are arranged on the plurality of arc clamping plates 33, the plurality of filter screens 35 are arranged in a V shape, and the plurality of filter screens 35 are slidably connected with the plurality of arc clamping plates 33.

[0059] In this embodiment, when the fluid enters the connecting pipe through the branch pipe 2, it is discharged into the filter cartridge 32. In the filter cartridge 32, the fluid is filtered by the plurality of V-shaped filter screens 35, and the impurities therein are removed. The filtered fluid then enters the main body of the flowmeter body 3 for measurement. Since the filter screen 35 is slidably connected with the arc-shaped clamping plate 33, when the filter screen 35 is clogged or needs to be cleaned, the user can conveniently take it out of the filter cartridge 32 for replacement or cleaning, so as to ensure the filtering effect. Through the design of the filter cartridge 32 and the filter screen 35, the impurities in the fluid are effectively removed, the interference of the impurities on the measurement mechanism of the flowmeter body 3 is reduced, and the measurement accuracy is improved. The design of the filter cartridge 32 and the filter screen 35 protects the measurement mechanism of the flowmeter body 3 from erosion by impurities, prolonging its service life. The design of the sliding connection between the filter screen 35 and the arc-shaped clamping plate 33 enables the filter screen 35 to be conveniently taken out of the filter cartridge 32 for replacement or cleaning, reducing maintenance cost and time. At the same time, the V-shaped design not only increases the filtering area of the filter screen 35, but also improves the trapping efficiency of impurities.

[0060] In another embodiment of the application, the filter cartridge 32 is detachably provided with an arc-shaped cover plate 34, the inner wall of the arc-shaped cover plate 34 is fixedly connected with the plurality of filter screens 35, a sealing strip 36 is sleeved on the arc-shaped cover plate 34, and the sealing strip 36 is matched with the arc-shaped notch of the filter cartridge 32.

[0061] In this embodiment, when the filter screen 35 needs to be replaced or cleaned, the user can first remove the fixing bolts on the arc cover 34, and then remove the arc cover 34 together with the filter screen 35 thereon from the filter cartridge 32. Since the filter screen 35 is fixedly connected to the arc cover 34, they can be conveniently taken out and replaced as a whole. When the arc cover 34 is reinstalled, the sealing strip 36 will fit tightly on the arc-shaped notch of the filter cartridge 32 to ensure sealing.
