The device uses a lever structure to simplify the installation process, is compatible with lifters of different specifications, effectively improves testing efficiency, and provides key experimental data support for optimizing the hydraulic system design of lifters and ensuring the stability and safety of ship navigation.

[0003] When conducting thrust tests on the outboard motor lifter of an electric boat, it is necessary to test the performance of the lifter under different working conditions. However, the existing lifter thrust test device has a relatively simple function and is difficult to meet the testing needs under different working conditions. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing outboard motor thrust test devices, which have limited functionality and are unable to meet the testing requirements under different working conditions. Therefore, this invention proposes an electric boat outboard motor thrust test device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The experimental apparatus for testing the thrust of the outboard motor lifter of an electric boat includes: A platform is provided, with a power switch fixedly installed on one side and a control box fixedly installed on the top of the other side. A power frame is provided on the side of the platform away from the power switch, and counterweights of different weights can be detachably installed on one side of the power frame.

[0006] In one possible design, a mounting plate is welded to the top of the side of the platform away from the power switch, and a connecting plate is fixedly connected to one side of the mounting plate by bolts. A first rotating seat is fixedly connected to the top of the connecting plate, and the two ends of the first rotating seat are rotatably connected to the power frame.

[0007] In one possible design, a first connecting frame is fixedly connected to one side of the connecting plate, an electric push rod is provided on one side of the connecting plate, a second rotating seat is fixedly connected to the bottom end of the electric push rod, the second rotating seat is rotatably connected to the first connecting frame via a rotating shaft, the second connecting frame is fixedly connected inside the power frame, and the top end of the piston rod of the electric push rod is rotatably connected to the second connecting frame via a rotating shaft.

[0008] In one possible design, two rotating frames are fixedly connected to the outside of the power frame, and two mating frames are fixedly connected to one side of the counterweight. The rotating frames and the mating frames are fixedly connected by bolts.

[0009] In one possible design, a stroke sensor is fixedly installed on the inner wall of the bottom of the electric push rod, the detection head of the stroke sensor is mounted on the piston rod, and a PLC controller is installed inside the control box.

[0010] In one possible design, the switch is electrically connected to the control box, the electric actuator, and the stroke sensor.

[0011] In this application, a switch is installed on one side of the platform for power on / off control, and a control box is installed on the top for operation control. The mounting plate and connecting plate on one side of the platform are fixed together with bolts. The power frame is rotatably connected to the first rotating seat. Simultaneously, an electric push rod located between the connecting plate and the power frame pushes the power frame to rotate around the first rotating seat via the extension and retraction of its piston rod. A counterweight is installed on one side of the power frame through a connection between the rotating frame and the mating frame. Different weights of counterweights can be replaced according to weight requirements. The main power switch for the control box and electric push rod is turned on. The switch button on the control box is turned on, and the forward rotation button is pressed. The piston rod of the electric push rod extends, pushing the power frame and causing the counterweight to rotate upwards around the first rotating seat. At this time, the stroke sensor located inside the first rotating seat converts the mechanical movement of the electric push rod piston rod into an electrical signal, which is transmitted to the PLC controller inside the control box. The data is displayed on the monitor on the top of the control box. When the power frame rotates to the mating position… When the desired angle is reached, press the forward button again to stop the piston rod of the electric push rod. Press the reverse button to retract the piston rod. At this time, the stroke sensor located in the first rotating seat converts the mechanical movement of the electric push rod piston rod into an electrical signal, which is transmitted to the PLC controller inside the control box. The data is displayed on the display on the top of the control box. When the power frame rotates to the appropriate angle, press the reverse forward button again to stop the piston rod of the electric push rod. Alternatively, press the automatic button to extend the piston rod of the electric push rod, pushing the power frame to rotate upward. When it rotates to the maximum angle, it stops rotating, and the display in the control box counts down for fifteen seconds. After the countdown ends, the piston rod of the electric push rod retracts, causing the power frame to rotate downward. Throughout the entire rotation process, the stroke sensor automatically converts the mechanical movement of the electric push rod piston rod into an electrical signal, which is transmitted to the PLC controller inside the control box. The data is displayed on the display on the top of the control box.

[0012] Beneficial effects: In this utility model, the electric boat outboard motor thrust test device can flexibly replace the counterweights of different weights according to the experimental requirements to meet diverse test conditions; at the same time, the stroke sensor can accurately convert the mechanical movement of the electric push rod piston rod into electrical signals, so as to realize the accurate acquisition and display of experimental data. In this utility model, the electric boat outboard motor tilter thrust test device can precisely control the tilting angle of the power frame; it also has an automatic mode, which can automatically complete the tilting and countdown rotation actions according to the preset program, and realize intelligent experimental control in conjunction with the PLC controller in the control box. In this invention, the experimental device for the thrust of the outboard motor lifter of an electric boat can not only flexibly adapt to different testing needs and accurately acquire data, but also provide a variety of operating modes and intelligent control, effectively improving experimental efficiency and accuracy.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figure 1 The thrust experimental apparatus consists of a rectangular steel frame structure, with a switch 2 bolted to one side to control the power supply to the entire apparatus. A control box 3 is welded to the top of the frame 1. The control box 3 has operation buttons and a display on its surface and integrates a PLC controller for controlling the experimental process and displaying experimental data.

[0017] Reference Figure 1 and Figure 2 A mounting plate 6 is welded to the top of the side of the platform 1 away from the switch 2, and the mounting plate 6 is perpendicular to the platform 1. A connecting plate 7 is fixedly connected to one side of the mounting plate 6 by M10 bolts. The connecting plate 7 is a rectangular steel plate, and a first rotating seat 8 is welded to the center of its top. Both ends are rotatably connected to the power frame 5 through rotating shafts, so that the power frame 5 can rotate around the rotating shafts.

[0018] Reference Figure 3 The power frame 5 is a rectangular steel frame structure, with two rotating frames 13 welded and fixed to its outer side. The counterweight 4 is a rectangular steel block, with two mating frames 14 welded and fixed to one side. The mating frames 14 are U-shaped steel plates. The rotating frames 13 and mating frames 14 are fixedly connected by M8 bolts, realizing a detachable connection between the counterweight 4 and the power frame 5. According to experimental requirements, the counterweight 4 can be replaced with different weights to meet diverse testing conditions.

[0019] Reference Figure 1 and Figure 2 A first connecting frame 9, a triangular steel plate, is welded and fixed to one side of the connecting plate 7 to support the electric push rod 11. A second rotating seat 10 is welded and fixed to the bottom of the electric push rod 11, and the second rotating seat 10 is rotatably connected to the connecting frame 9 via a rotating shaft. A connecting frame 12, a rectangular steel plate, is welded and fixed inside the power frame 5, and the top of the piston rod of the electric push rod 11 is rotatably connected to the connecting frame 12 via a rotating shaft. A stroke sensor is installed on the inner wall of the bottom of the electric push rod 11, and the detection head is mounted on the piston rod to detect the extension and retraction displacement of the piston rod.

[0020] This application can be used in the field of electric boats, or in other fields applicable to this application.

[0021] In another embodiment: Reference Figures 1 to 3 This experimental device for testing the thrust of an outboard motor lifter in electric boats is applied to the field of electric boats. The power switch 2 is electrically connected to the control box 3, electric push rod 11, and stroke sensor via cables, forming a complete control loop. During the experiment, the power switch 2 is turned on to supply power to the device, and the movement of the electric push rod 11 is controlled by the operation buttons on the control box 3. Pressing the forward rotation button extends the piston rod of the electric push rod 11, pushing the power frame 5 to cause the counterweight 4 to rotate upwards around the first rotating seat 8. The stroke sensor converts the mechanical movement of the piston rod into an electrical signal, which is transmitted to the PLC controller in the control box 3, and the displacement data is displayed in real time on the top display. When the power frame 5 rotates to the appropriate angle, pressing the forward rotation button again stops the piston rod from moving.

[0022] refer to Figures 1 to 3Pressing the reverse button retracts the piston rod of the electric push rod 11, causing the power frame 5 to flip downwards. The stroke sensor converts the mechanical motion back into an electrical signal, enabling data acquisition and display. When the power frame 5 rotates to the appropriate angle, pressing the reverse button stops the piston rod movement. Alternatively, pressing the automatic button extends the piston rod of the electric push rod 11, pushing the power frame 5 upwards. It automatically stops when it reaches the maximum angle, and the display screen in the control box 3 starts a 15-second countdown. After the countdown ends, the piston rod automatically retracts, causing the power frame 5 to flip downwards. Throughout the process, the stroke sensor continuously acquires and displays data. Different weights of counterweights 4 can be used to simulate thrust testing requirements under different working conditions. The cooperation between the stroke sensor and the PLC controller enables accurate acquisition and real-time display of experimental data.
