Description

Technical Field

[0001] This utility model relates to the technical field of positioning adjustment devices, specifically to a positioning adjustment device for use on a water tank testing instrument. Background Technology

[0002] In the past, the installation and positioning of equipment such as flow meters and depth gauges in water tank testing instruments were all done manually inside the water tank.

[0003] The installation of the instrument by manual operation in the water tank is difficult and poses certain safety hazards. Furthermore, the height and orientation of the instrument installation require manual adjustment and measurement of the probe rod, which is extremely time-consuming and makes it difficult to ensure the installation and positioning accuracy of the instrument. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning and adjustment device for mounting instruments in a water tank test, so as to solve the shortcomings of existing water tank test instruments and equipment, which are difficult to install and position, have poor accuracy, and are time-consuming.

[0005] To achieve the objective of this invention, the following technical solution is adopted:

[0006] This utility model discloses a positioning and adjustment device for mounting a water tank testing instrument. It includes: a base, a first hinge seat, an electric actuator, a second hinge seat, a bracket, a third hinge seat, a lifting frame, a lifting screw motor, a probe fixing block, a probe motor, a lifting screw, a probe, and a clamp. The base is mounted on the water tank. The first hinge seat is mounted on the base. One end of the electric actuator is hinged to the first hinge seat, and the other end of the electric actuator is hinged to the second hinge seat fixed to the lifting frame. A bracket is also mounted on the base, and the upper end of the bracket is hinged to the third hinge seat fixed to the lifting frame. The electric actuator, bracket, and lifting frame form a four-bar linkage. A lifting mechanism is mounted on the lifting frame. The lifting screw is movably connected to the lifting frame. A lifting screw motor is installed at one end of the lifting screw, which drives the lifting screw to rotate. A probe fixing block is mounted on the lifting screw and is movably connected to the lifting screw. As the lifting screw rotates, the probe fixing block moves up and down along the lifting screw. A probe is also mounted on the probe fixing block, passing through the probe fixing block and parallel to the lifting screw. The probe is movably connected to the probe fixing block. A probe motor is installed at the upper end of the probe, which is fixed to the probe fixing block and drives the probe to rotate. A clamp is installed at the lower end of the base to clamp the probe.

[0007] Furthermore, the lifting frame includes a vertical side wall, an upper end wall, and a lower end wall. The upper end wall and the lower end wall are respectively fixed to the upper and lower ends of the vertical side wall. The second hinge seat and the third hinge seat are respectively mounted on the vertical side wall. One end of the lifting screw passes through the upper end wall and is mounted on the lower end wall. A lifting screw motor is mounted on the upper end of the lifting screw and is fixed on the upper end wall.

[0008] Furthermore, the upper section of the probe is cylindrical, and the lower section is elliptical cylindrical.

[0009] Furthermore, the upper section of the probe rod is the probe rod part that is connected to the probe rod motor and passes through the probe rod fixing block, and the lower section of the probe rod is the remaining part of the probe rod after removing the upper section.

[0010] Furthermore, the clamping device includes: a first clamping jaw, a clamping frame, a second clamping jaw, a clamping shaft, and a clamping motor. The clamping frame is fixed to the lower end of the base, and the clamping shaft is installed between the left and right ends of the clamping frame. The clamping shaft is movably connected to the clamping frame. A clamping motor is installed at one end of the clamping shaft, and the clamping motor drives the clamping shaft to rotate. The first clamping jaw and the second clamping jaw are respectively mounted on the clamping shaft. The rotation of the clamping shaft drives the first clamping jaw and the second clamping jaw to move relatively closer or relatively farther apart.

[0011] Furthermore, the clamping shaft is a screw shaft.

[0012] Furthermore, the clamping device also includes a support block, which is fixed at the center of the left and right ends of the clamping frame. The clamping shaft passes through the support block, and the screw on the clamping shaft between the support block and the left end of the clamping frame is either left-handed or right-handed, while the screw on the clamping shaft between the support block and the right end of the clamping frame is either right-handed or left-handed.

[0013] Furthermore, the ends of the first and second clamping claws have grooves corresponding to the cross-section of the probe rod.

[0014] Furthermore, the probe motor is a servo motor.

[0015] Furthermore, the first clamping claw and the second clamping claw are symmetrically arranged. The lower parts of the first clamping claw and the second clamping claw are vertical. The lower parts of the first clamping claw and the second clamping claw are respectively fitted onto the clamping shaft. The upper parts of the first clamping claw and the second clamping claw are generally L-shaped. The bottom surface of the horizontal part of the L-shape is connected to the lower part of the first clamping claw or the second clamping claw. The side of the vertical part of the L-shape is provided with a groove with a curved inner wall. The groove on the first clamping claw and the groove on the second clamping claw are arranged opposite to each other.

[0016] Furthermore, the clamping frame is fixed to the end of the horizontal part of the L-shaped base. The clamping frame has a U-shaped cross-section. One end of the clamping frame is connected to the base, and the other end is equipped with a clamping motor.

[0017] Furthermore, the base is L-shaped, and includes an integrally formed vertical part and a horizontal part. The first hinge seat and the bracket 4 are disposed on the top surface of the vertical part, and the clamp is connected to the end surface of the horizontal part.

[0018] The positioning and adjustment device of this utility model for mounting on a water tank testing instrument has the following advantages compared with existing devices:

[0019] 1. In this utility model, the lifting frame can be automatically flipped by an electric push rod. The automatic flipping mechanism can flip the probe to the required height, which makes it convenient for personnel to install and disassemble the mounted instrument at the side of the water tank without having to go into the water tank for installation, making the operation convenient.

[0020] 2. After the instrument is manually installed, all flipping, lifting, and rotating functions of the entire mechanism can be automatically controlled.

[0021] 3. This utility model simulation device can simulate various test conditions and greatly reduce manpower, material resources and time costs through adjustment.

[0022] 4. The positioning and adjustment device for mounting water tank testing instruments provided by this utility model is an automated mechanism. Through the mechanism's flipping, the probe's braking, lifting, and rotation, the instrument can be easily installed, and the probe can be automatically lifted, rotated, and positioned.

Detailed Implementation

[0029] like Figure 1 As shown, the positioning and adjustment device for mounting a water tank testing instrument according to this utility model includes: a base 13, a first hinge seat 1, an electric actuator 2, a second hinge seat 3, a bracket 4, a third hinge seat 5, a lifting frame 6, a lifting screw motor 7, a probe fixing block 8, a probe motor 9, a lifting screw 10, a probe 11, and a clamping device 19.

[0030] The base 13 is L-shaped and includes an integrally formed vertical part and a horizontal part. The first hinge seat 1 and the bracket 4 are disposed on the top surface of the vertical part, and the clamp 19 is connected to the end surface of the horizontal part.

[0031] The base 13 can be bolted to the water tank. A first hinge seat 1 is mounted on the top surface of the base 13. One end of the electric actuator 2 is hinged to the first hinge seat 1, and the other end of the electric actuator 2 is hinged to a second hinge seat 3 fixed on the lifting frame 6. Typically, the first hinge seat 1 and the second hinge seat 3 are equipped with hinge shafts. The electric actuator 2 has rings at both ends, which are fitted onto the hinge shafts to achieve hinged connections between the two ends of the electric actuator 2 and the first hinge seat 1 or the second hinge seat 3, respectively.

[0032] The lifting frame 6 includes a vertical side wall 20, an upper end wall 21, and a lower end wall 22. The upper end wall 21 and the lower end wall 22 are respectively fixed to the upper and lower ends of the vertical side wall 20. The upper end wall 21 and the lower end wall 22 are horizontally arranged and are perpendicular to the vertical side wall 20. The second hinge seat 3 and the third hinge seat 5 are respectively arranged on the side of the vertical side wall 20 facing the first hinge seat 1.

[0033] A bracket 4 is also mounted on the base 13. The bottom end of the bracket 4 is fixed to the top surface of the base 13, and the upper end of the bracket 4 is hinged to the third hinge seat 5 fixed on the lifting frame 6. The electric push rod 2, the bracket 4 and the lifting frame 6 form a linkage mechanism.

[0034] In this invention, the electric actuator 2 is a common electric actuator on the market. When the working button of the electric actuator is pressed, the movable end of the electric actuator 2 can extend or retract along the fixed end of the electric actuator 2. Since the electric actuator 2 is hinged to the first hinge seat 1 and the lifting frame 6, when the movable end of the electric actuator 2 extends or retracts, it can drive the lifting frame 6 to rotate clockwise or counterclockwise.

[0035] A lifting screw motor 7 is mounted on the upper surface of the upper end wall 21. The bottom end of the lifting screw 10 passes through the upper end wall 21 and is mounted on the lower end wall 22. The output shaft of the lifting screw motor 7 is connected to the top end of the lifting screw 10. When the lifting screw motor 7 is working, it drives the lifting screw 10 to rotate. The lifting screw 10 is clearance-fitted with the upper end wall 21 and the lower end wall 22, or bearings are provided at the connection points between the lifting screw 10 and the upper end wall 21 and the lower end wall 22. The lifting screw 10 is connected to the upper end wall 21 through bearings, and the lifting screw 10 is connected to the lower end wall 22 through bearings. When the lifting screw motor 7 is working, it drives the lifting screw 10 to rotate relative to the upper end wall 21 and the lower end wall 22.

[0036] A probe fixing block 8 is fitted onto the lifting screw 10. In a specific embodiment, a protrusion is provided at one end of the probe fixing block 8, and a round hole is provided on the protrusion. The round hole on the protrusion is fitted onto the lifting screw 10. As the lifting screw 10 rotates, the probe fixing block 8 moves up and down along the lifting screw 10.

[0037] The lifting screw 10 and the probe fixing block 8 form a screw-slider structure. The outer surface of the portion of the lifting screw 10 located between the upper end wall 21 and the lower end wall 22 is threaded. The inner wall of the circular hole on the protrusion at one end of the probe fixing block 8 is threaded. The lifting screw 10 engages with the thread on the inner wall of the circular hole. When the lifting screw 10 rotates, the probe fixing block 8 moves axially along the lifting screw 10. The rotational motion of the lifting screw 10 is converted into linear motion of the probe fixing block 8, driven by the lifting screw motor 7. The lifting screw motor 7 drives the lifting screw 10 to rotate via a coupling, thereby pushing the probe fixing block 8 to move linearly up and down along the lifting screw 10.

[0038] A probe 11 is also mounted on the probe fixing block 8. The bottom end of the probe 11 passes through the probe fixing block 8 and is parallel to the lifting screw 10. A probe motor 9 is mounted on the upper surface of the probe fixing block 8. The probe motor is a servo motor, and the output shaft of the probe motor 9 is connected to the top end of the probe 11. When the probe motor 9 is working, it drives the probe 11 to rotate. The probe 11 and the probe fixing block 8 are either clearance-fitted or a bearing is provided at the connection between the probe 11 and the probe fixing block 8. The probe 11 and the probe fixing block 8 are connected by the bearing. When the probe motor 9 is working, it drives the probe 11 to rotate relative to the probe fixing block 8.

[0039] The upper section of the probe rod 11 is cylindrical, and the lower section is elliptical cylindrical. The upper section of the probe rod 11 is the part that connects to the probe rod motor 9 and passes through the probe rod fixing block 8. The lower section of the probe rod 11 is the remaining part of the probe rod 11 after removing the upper section. A clamping device 19 is installed at the lower end of the base 13, which is used to clamp the probe rod 11.

[0040] like Figure 4 and5 As shown, the clamping device 19 includes: a first clamping jaw 12, a clamping frame 14, a support block 15, a second clamping jaw 16, a clamping shaft 17, and a clamping motor 18.

[0041] The clamping frame 14 is fixed to the end of the horizontal part of the L-shaped base 13. The clamping frame 14 has a U-shaped cross-section. The outer surface of the left end of the clamping frame 14 is connected to the base 13 by bolts, and the clamping motor 18 is provided on the outer side of the right end. The clamping shaft 17 is a screw shaft, which is installed between the left and right ends of the clamping frame 14. The clamping shaft 17 can be movably connected to the left and right ends of the clamping frame 14 through bearings. The output shaft of the clamping motor 18 is connected to one end of the clamping shaft 17 through a coupling. When the clamping motor 18 works, it drives the clamping shaft 17 to rotate.

[0042] The support block 15 is fixed at the center of the left and right ends of the clamping frame 14. The clamping shaft 17 passes through the support block 15. The screw on the clamping shaft 17 between the support block 15 and the left end of the clamping frame 14 is left-handed or right-handed. The screw on the clamping shaft 17 between the support block 15 and the right end of the clamping frame 14 is right-handed or left-handed. The first clamping claw 12 and the second clamping claw 16 are respectively movably mounted on the clamping shaft 17. The rotational motion of the clamping shaft 17 is converted into the linear motion of the first clamping claw 12 and the second clamping claw 16. The rotation of the clamping shaft 17 drives the first clamping claw 12 and the second clamping claw 16 to move relatively closer or relatively farther away. The ends of the first clamping claw 12 and the second clamping claw 16 have grooves 23 corresponding to the cross-section of the probe rod 11.

[0043] The first clamping jaw 12 and the second clamping jaw 16 are symmetrically arranged. The lower parts of the first clamping jaw 12 and the second clamping jaw 16 are vertical and are respectively fitted onto the clamping shaft 17. The upper parts of the first clamping jaw 12 and the second clamping jaw 16 are L-shaped. The bottom surface of the horizontal part of the L-shape is connected to the lower part of the first clamping jaw 12 or the second clamping jaw 16. The vertical part of the L-shape has a groove 23 with a curved inner wall. The groove 23 on the first clamping jaw 12 and the groove 23 on the second clamping jaw 16 are arranged opposite to each other. When the clamping motor 18 is working, the elliptical shape of the lower part of the probe 11 is located between the groove 23 on the first clamping jaw 12 and the groove 23 on the second clamping jaw 16. The elliptical shape of the lower part of the probe 11 is clamped by the first clamping jaw 12 and the second clamping jaw 16.

[0044] like Figure 1 As shown, the positioning and adjustment device of this utility model for mounting on a water tank testing instrument is in its initial state. At this time, hydrological detection equipment is installed at the bottom end of the probe 11. Figure 1 The equipment for hydrological surveys was not depicted in the drawing. After preparations are complete, such as... Figure 5 As shown, the clamp 19 is opened. At this time, the clamp 19 does not clamp the probe rod 11. The lifting screw motor 7 is started, as follows. Figure 2As shown, after the lifting screw motor 7 drives the probe rod 11 to the desired position in the water, the lifting screw motor 7 stops working, and the probe rod motor 9 drives the probe rod 11 to rotate 180° back and forth. The probe rod motor 9 controls the rotation frequency and rotation angle of the probe rod 11. When the probe rod 11 needs to be fixed, such as... Figure 4 As shown, clamping device 19 is closed to clamp probe 11. When the positioning and adjustment device of this utility model for water tank testing instrument needs maintenance, first open clamping device 19 to loosen probe 11, then start lifting screw motor 7 to return probe 11 to its original position. Figure 1 After reaching the initial state, stop the lifting screw motor 7, start the electric actuator 2, and rotate the lifting frame 6 counterclockwise by 90° to... Figure 3 As shown in the diagram, the equipment mounted on the lower end of probe 11 can be brought out of the water along with this device for maintenance.
