Technical Field

[0001] The utility model relates to the field of metering positive and reverse flow rates, and particularly relates to a water meter for metering positive and reverse flow rates. Background Art

[0002] For marine equipment, it is crucial to measure the positive and reverse flow rates during ascending and descending, which is of great significance for maintaining the equipment and understanding its status.

[0003] Positive and reverse flow rate metering is an important part of the flow rate metering field. As the proportion of positive and reverse flow rates in the flow rate metering field is increasing, the demand for positive and reverse flow water meters in real life is also increasing.

[0004] In the market, instruments for measuring the positive and reverse liquid flow rates used on marine equipment are not common, and most of them need to consider power supply and sealing problems. At the same time, it is more difficult to resist signal interference underwater. Summary of the Invention

[0005] Aiming at the deficiencies of existing positive and reverse flow rate metering instruments, the utility model provides a water meter for metering positive and reverse flow rates, which has the function of metering positive and reverse flow rates, and has characteristics such as stability and high accuracy. Moreover, it is a pure mechanical structure, which can avoid problems such as electromagnetic interference.

[0006] To achieve the above object, the utility model provides the following technical solution: A water meter for metering positive and reverse flow rates includes a metering mechanism, a transmission mechanism, and an indicating mechanism. The transmission mechanism is arranged inside the upper cover of the metering main body of the metering mechanism, and the indicating mechanism is arranged above the upper cover of the metering main body. The upper-end gear of the rotating shaft of the metering mechanism passes through the metering main body frame and meshes with the rotating shaft gear I of the transmission mechanism, and the bottom gear of the rotating shaft gear VI of the indicating mechanism passes through the gear box and meshes with the gear of the transmission mechanism.

[0007] In the above technical solution, the metering mechanism includes a front rectifier, a rear rectifier, a worm, a wing wheel, a rotating shaft, a metering main body frame, and an upper cover of the metering main body. The front rectifier, the wing wheel, the rotating shaft, and the rear rectifier are sequentially arranged inside the metering main body frame. The spiral part of the worm is arranged inside the wing wheel, the rotating shaft is vertically arranged inside the gear of the worm, and the gear of the worm meshes with the bottom gear of the rotating shaft. The front rectifier is arranged at the end of the spiral part of the worm, the rear rectifier is arranged at the end of the gear of the worm, and the upper cover of the metering main body is arranged at the upper end of the metering main body frame.

[0008] In the above technical scheme, the transmission mechanism comprises a sealing shaft plate, shaft plate I, shaft plate II, a pillar, a rotating shaft gear I, a rotating shaft gear II, a rotating shaft gear III, a rotating shaft gear IV, a supporting member, a rotating shaft gear V and a gear; the shaft plate II is embedded in the bottom of the shaft plate I, the supporting member is arranged on the shaft plate I, the rotating shaft gear V is arranged on the supporting member, the gear (2-12) is arranged on the upper end of the rotating shaft of the rotating shaft gear V, the rotating shaft gear I, the rotating shaft gear II, the rotating shaft gear (2-8) and the rotating shaft gear IV are arranged on the shaft plate I in sequence, the rotating shaft gear IV is meshed with the rotating shaft gear V, the rotating shaft gear III is meshed with the rotating shaft gear IV, the rotating shaft gear II is meshed with the rotating shaft gear III, and the rotating shaft gear I is meshed with the rotating shaft gear II; the sealing shaft plate is connected to the shaft plate I through the pillar.

[0009] In the above technical solution, the indicating mechanism uses a water meter of model LXN-50.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model drives the subsequent worm and the shaft gear through the rotation of the impeller, and finally displays the positive and negative flow on the indicating mechanism under the transmission of the precise transmission ratio of the shaft gear in the transmission mechanism, and accurately measures the liquid flow when the marine equipment rises and dives.

[0012] The utility model uses the kinetic energy generated by the fluid based on the number of revolutions of the impeller to drive the rotation of the worm gear transmission device, which is transmitted to the indicating mechanism through the rotating shaft, and finally displays the total amount of seawater. It does not involve power supply and other issues, and fully solves the problems of underwater circuit sealing and signal interference. At the same time, the working pressure and seawater corrosion under seawater are fully considered in the design to prevent salt spray and pressure resistance. BRIEF DESCRIPTION OF THE DRAWINGS
