Description

Technical Field

[0001] This utility model relates to the field of regulator technology, specifically to a hydrological instrument installation angle regulator. Background Technology

[0002] Flow measurement methods have evolved from traditional rotor current meters to acoustic Doppler current meters (ADCPs). Since the introduction of ADCPs in the 1990s, measurement methods have been improved, and hydrology has entered a period of rapid development. ADCPs are divided into mobile and fixed types, with fixed ADCPs further divided into base-mounted and horizontal H-ADCPs, which are widely used in online flow monitoring.

[0003] Currently, when H-ADCP is used for underwater measurements, factors such as water flow may cause deviations in the measurement position, affecting measurement accuracy. Therefore, H-ADCP adjustments are necessary. Existing pitch and roll adjustments are generally only mechanical and manual, which is laborious and time-consuming, and cannot quickly adjust the H-ADCP to the required position.

[0004] Therefore, there is an urgent need to propose a hydrological instrument installation angle adjuster to solve the above-mentioned problems. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a hydrological instrument mounting angle adjuster that automatically adjusts the H-ADCP body for lateral and longitudinal adjustment during underwater operation by setting a first motor and a second motor respectively, offering diverse adjustment directions and improving measurement accuracy.

[0006] The technical solution provided by this utility model is as follows:

[0007] A hydrological instrument mounting angle adjuster includes an H-ADCP body and a housing. The H-ADCP body is detachably connected to a connecting plate. A hollow base is provided on the exterior of one side of the housing, and the connecting plate is located in the hollow part of the base. Fixing plates are symmetrically arranged on both sides of the base, and each fixing plate is detachably connected to the housing via a movable rod. A first motor and a second motor are arranged perpendicularly to each other inside the housing. The rotation shaft of the first motor is connected to the connecting plate, and the rotation shaft of the second motor passes through one side of the housing and is connected to a transmission gear. The transmission gear meshes with a fixed gear, and the fixed gear is sleeved on the corresponding movable rod on the same side. A control line interface is provided on the housing, and the first motor and the second motor are respectively connected to the control line interface, which is connected to a power source.

[0008] Furthermore, a cover plate is detachably connected to one side of the housing.

[0009] Furthermore, a connecting seat is provided at the connection point between the rotating shaft of the first motor and the connecting plate.

[0010] Furthermore, the connecting disk is circular.

[0011] Furthermore, the surface of the connecting plate is symmetrically provided with multiple columns, and the end of the H-ADCP body is provided with column holes that are adapted to the columns, with each column inserted into the corresponding column hole.

[0012] Furthermore, the base and the fixed plate are respectively provided with slots and through holes adapted to the movable rods, with one end of each movable rod rotatably connected to the slot and the other end rotatably connected to the through hole.

[0013] Furthermore, both the rotating shafts of the first motor and the second motor are fitted with copper sleeves and oil seals.

[0014] Furthermore, the transmission gear is circular, the fixed gear is fan-shaped, and one end of the fixed gear is fitted with a through hole that matches the movable rod.

[0015] The beneficial effects of this utility model are:

[0016] 1) The rotation of the first motor drives the connecting plate to rotate laterally, which in turn drives the H-ADCP body connected to the connecting plate to adjust laterally;

[0017] 2) The rotation of the second motor drives the transmission gear and the fixed gear to rotate, which in turn drives the entire housing to move longitudinally, thereby driving the H-ADCP body connected to the housing to adjust longitudinally.

[0018] 3) The rotating shafts of the first and second motors are equipped with copper sleeves and oil seals, which facilitates double sealing during underwater operation of the motors and extends their service life.

[0019] 4) The cover is installed to ensure the airtightness of the box;

[0020] 5) The connecting seat is provided to ensure the stability of the connection between the rotating shaft of the first motor and the connecting plate. Attached Figure Description

[0029] like Figures 1 to 4 As shown, a hydrological instrument mounting angle adjuster includes an H-ADCP body 1 and a housing 2. The H-ADCP body 1 is detachably connected to a connecting plate 3. A hollow base 4 is provided on the outside of one side of the housing 2. The connecting plate 3 is located in the hollow part of the base 4. Fixing plates 5 are symmetrically arranged on both sides of the base 4. Each fixing plate 5 is detachably connected to the housing 2 via a movable rod 6. A first motor 7 and a second motor 8 are arranged perpendicularly to each other inside the housing 2. Both the first motor 7 and the second motor 8 are stepper motors. The rotating shaft of the first motor 7 is connected to the connecting plate 3. The rotating shaft of the second motor 8 passes through one side of the housing 2 and is connected to a transmission gear 9. The transmission gear 9 meshes with a fixed gear 10. The fixed gear 10 is sleeved on the corresponding movable rod 6 on the same side. A control line interface 11 is provided on the housing 2. The first motor 7 and the second motor 8 are respectively connected to the control line interface 11. The control line interface 11 is connected to a power source.

[0030] As a further technical solution in this embodiment, a cover plate 12 is detachably connected to one side of the box 2.

[0031] As a further technical solution of this embodiment, a connecting seat is provided at the connection between the rotating shaft of the first motor 7 and the connecting plate 3.

[0032] As a further technical solution in this embodiment, the connecting disk 3 is circular.

[0033] As a further technical solution of this embodiment, the surface of the connecting plate 3 is symmetrically provided with multiple columns 13, and the end of the H-ADCP body 1 is provided with column 13 holes adapted to the columns 13, and each column 13 is inserted into the corresponding column 13 hole.

[0034] As a further technical solution of this embodiment, the base 4 and the fixing plate 5 are respectively provided with slots and through holes adapted to the movable rods 6, one end of each movable rod 6 is rotatably connected to the slot, and the other end is rotatably connected to the through hole.

[0035] As a further technical solution in this embodiment, the rotating shafts of the first motor 7 and the second motor 8 are both fitted with copper sleeves and oil seals.

[0036] As a further technical solution of this embodiment, the transmission gear 9 is circular, the fixed gear 10 is fan-shaped, and one end of the fixed gear 10 is fitted with a through hole that matches the movable rod 6.

[0037] The working principle of this utility model:

[0038] In this invention, the first motor 7 and the second motor 8 are arranged perpendicularly to each other and installed inside the housing 2. The first motor 7 is perpendicular to the H-ADCP, and its motor shaft extends forward out of the housing 2 and connects to the connecting plate 3. When the motor rotates left and right, it drives the connecting plate 3 to rotate left and right, thereby adjusting the left and right rotation of the H-ADCP to keep it horizontal, thus realizing the lateral adjustment of the H-ADCP. The second motor 8 is perpendicular to the H-ADCP, and its motor shaft extends out of the housing 2. A transmission gear 9 is installed at the end of the shaft and meshes with the fixed gear to form a relative motion. When the motor rotates, it drives the H-ADCP to move up and down along the shaft to keep it horizontal, thus realizing the longitudinal adjustment of the H-ADCP.

[0039] In addition, the H-ADCP can be connected to a shore-based stepper control module. When the H-ADCP is working, it outputs a real-time pitch angle. The stepper control module controls two motors to adjust the H-ADCP angle according to the output angle, so that the angle is within the set pitch angle range.
