[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 As shown, the present application provides a first embodiment, which is a straight-wing rudder propeller testing device, comprising:

[0041] The frame 101 has a trailer connection portion 102 disposed on the top of the frame 101.

[0042] The motor 104 is disposed on the frame 101 and is used to drive the straight-wing rudder propeller 200 to work.

[0043] A sensor is used to detect the performance of the straight-wing rudder propeller 200 during operation.

[0044] The wave suppression mechanism 103 is connected to the frame 101 and is used to prevent water waves from directly hitting the sensor.

[0045] Specifically, the motor 104 can drive the straight-wing rudder propeller 200 to work. The straight-wing rudder propeller 200 can be placed in a towing pool, which is used to simulate a real application environment with waves. The trailer of the towing pool can be connected to the trailer connection part 102 of the frame 101, and the connection method can be welding or other connection methods. The trailer can drive the frame 101 and the straight-wing rudder propeller 200 to move in a straight line. The mechanical properties of the straight-wing rudder propeller 200 during the working process can be detected by the sensor.

[0046] Specifically, one or more sensors may be provided, and the types of the sensors may be different.

[0047] In this embodiment, if Figure 2 As shown, the wave-suppression mechanism 103 includes a bottom plate 1031, and a front plate 1032 and a rear plate 1033 are respectively arranged obliquely on both sides of the bottom plate 1031. The wave-suppression mechanism 103 also includes an annular enclosure structure 1035, and the annular enclosure structure 1035 is respectively connected to the bottom plate 1031, the front plate 1032 and the rear plate 1033. A clearance through hole 1034 is arranged on the bottom plate 1031. The clearance through hole 1034 is used for installing the straight-wing rudder propeller 200. Specifically, a part of the straight-wing rudder propeller 200 is located on the upper side of the clearance through hole 1034, and the blades of the straight-wing rudder propeller 200 are located below the clearance through hole 1034.

[0048] In this embodiment, a camera is provided on the frame 101. Specifically, the frame 101 is composed of a plurality of cross beams and longitudinal beams. On this basis, the frame 101 further includes an extension frame 111, on which a camera is provided. For example, a camera for photographing the straight-wing rudder propeller 200 may be provided. A camera for photographing other sensors or other structures may also be provided. The video or image taken by the camera can be used to analyze whether each mechanism is working normally.

[0049] In this embodiment, if Figure 3 As shown, the sensor includes a torque sensor 105, one end of the torque sensor 105 is connected to the motor 104, and the other end of the torque sensor 105 is connected to the input shaft of the straight-wing rudder propeller 200 through a coupling 106. The motor 104 is used to drive the straight-wing rudder propeller 200 to move through the torque sensor 105.

[0050] Specifically, when the straight-wing rudder propeller 200 moves forward in a pool with waves, the torque sensor 105 can obtain corresponding data in real time, and these data can be used to analyze the performance of the straight-wing rudder propeller 200 after being aggregated.

[0051] In this embodiment, if Figure 3 and Figure 4As shown, the sensor also includes a six-component force sensor 108, one end of which is connected to a lower cover shell 109, and the lower cover shell 109 is used to be connected to the housing 201 of the straight-wing rudder propeller 200, and the other end of the six-component force sensor 108 is connected to the bottom end of the upper bracket 107, and the motor 104 and the torque sensor 105 are fixed to the upper bracket 107, for example, the motor 104 is arranged on the top of the upper bracket 107, and the torque sensor 105 is arranged below the motor 104 and connected to the upper bracket 107, and the upper bracket 107 is connected to the upper cover shell 112 through the connecting plate 110, and the motor 104 and the torque sensor 105 are located inside the upper cover shell 112. The upper cover shell 112 can protect the motor 104 and the torque sensor 105. A flange structure is arranged on the top of the upper cover shell 112 for connecting other components. The upper cover shell 112 is cylindrical as a whole and can be divided into two parts, the upper part has a smaller diameter and the lower part has a larger diameter.

[0052] Specifically, when the straight-wing rudder propeller 200 is working in water, the straight-wing rudder propeller 200 will be affected by external force. Since one end of the six-component force sensor 108 is connected to the lower cover shell 109, and the lower cover shell 109 is connected to the shell 201 of the straight-wing rudder propeller 200, the six-component force sensor 108 can be used to measure the working straight-wing rudder propeller 200 to obtain corresponding mechanical data.

[0053] On the basis of the above, the upper cover shell 112 and the frame body 101 are in floating cooperation, that is, the upper cover shell 112 can move relative to the frame body 101 .

[0054] Specifically, Figure 1 and Figure 5 As shown, the frame 101 is provided with a first slide rail assembly 113, which may be composed of a slide rail and a slider. The first slide rail assembly 113 is provided with a moving plate 114, and both sides of the moving plate 114 are respectively connected to mechanical sensors 115 fixed to the frame 101. The moving plate 114 is provided with a through hole, and the upper end of the upper cover 112 passes through the through hole. The mechanical sensor 115 may be a tension sensor or other type of sensor.

[0055] Specifically, when the straight-wing rudder propeller 200 is working in water, the straight-wing rudder propeller 200 will be affected by external force, which will cause the upper cover shell 112 to move. The movement of the upper cover shell 112 will drive the movable plate 114 to move along the first slide rail assembly 113. Since mechanical sensors 115 are connected to both sides of the movable plate 114, corresponding data can be detected by the mechanical sensors 115.

[0056] In one embodiment, the movable plate 114 is provided with a plurality of guide sleeves 116, and guide posts 117 are provided in the guide sleeves 116, and each guide post 117 is respectively connected to the upper end of the upper cover shell 112, and a second slide rail assembly 119 is also provided on the frame 101 located above the upper cover shell 112, and the second slide rail assembly 119 can be composed of a slide rail and a slider, etc. A support frame 120 is provided on the second slide rail assembly 119, and a vertically arranged screw mechanism 118 is provided on the support frame 120, and the screw mechanism 118 is connected to the upper cover shell 112, and the lower end of the screw mechanism 118 is provided on the movable plate 114.

[0057] Specifically, the lead screw mechanism 118 may be a trapezoidal lead screw mechanism 118. The trapezoidal lead screw mechanism 118 has a good self-locking capability, which helps to ensure that the lead screw mechanism 118 can be self-locked after being adjusted into place, and will not move accidentally.

[0058] Specifically, the screw mechanism 118 of the present application can be operated manually, that is, the operator can stand at a high place and use a tool to rotate the screw mechanism 118 below.

[0059] Specifically, since the depth of water in each pool is different, the size of each straight-wing rudder propeller 200 is also different. In order to facilitate the adjustment of the vertical height position of the straight-wing rudder propeller 200 so that the blade of the straight-wing rudder propeller 200 is located at a predetermined position in the water, the present application is provided with the above-mentioned screw mechanism 118. The height of the upper cover shell 112 can be adjusted by the screw mechanism 118. Since the upper cover shell 112 is connected to the straight-wing rudder propeller 200 through other components, after the height of the upper cover shell 112 is adjusted, the height of the straight-wing rudder propeller 200 will also be adjusted accordingly. In this way, the height of the straight-wing rudder propeller 200 can be adjusted flexibly and accurately.

[0060] Furthermore, the present application is provided with a second slide rail assembly 119, and a support frame 120 is provided on the second slide rail assembly 119. The support frame 120 can move along the second slide rail assembly 119, and the arrangement direction of the second slide rail assembly 119 is consistent with the arrangement direction of the first slide rail assembly 113. This makes it possible for the support frame 120 to move accordingly when the upper cover shell 112 moves, and the screw mechanism 118 on the support frame 120 will not interfere with the movement of the upper cover shell 112.

[0061] It should be noted that when the straight-wing rudder propeller test device of the present application is used, the straight-wing rudder propeller 200 is connected to the straight-wing rudder propeller test device, that is, the straight-wing rudder propeller 200 is connected to the lower cover 109, and at the same time, the input shaft of the straight-wing rudder propeller 200 is connected to the torque sensor 105 through a coupling. The blades of the straight-wing rudder propeller 200 are located below the yielding through hole 1034 of the bottom plate 1031 of the wave suppression mechanism 103. A towing pool is also included, which is an existing technology. The towing pool includes a trailer, a pool and a wave maker, the trailer connection part 102 of the frame 101 is connected to the trailer, and the straight-wing rudder propeller 200 is located in the pool.

[0062] The present application provides a second embodiment, which is a straight-wing rudder propeller testing method. The testing method adopts the above-mentioned straight-wing rudder propeller testing device, and the straight-wing rudder propeller 200 is connected to the straight-wing rudder propeller testing device, and also includes a towing pool. The towing pool includes a trailer, a pool and a wave maker. The trailer connecting part 102 of the frame 101 is connected to the trailer, and the straight-wing rudder propeller 200 is located in the pool. The straight-wing rudder propeller 200 is driven to rotate by the motor 104, and the frame 101 is driven to move by the trailer, so that the straight-wing rudder propeller 200 moves in the pool with waves during the rotation process.

[0063] In the above test method, the moving speed of the straight-wing rudder propeller 200 in water can be obtained through the moving speed of the trailer, and the mechanical performance data of the straight-wing rudder propeller 200 in operation can be obtained through the torque sensor 105, the six-component force sensor 108, the tension sensor, etc. The present application can perform multiple mechanical performance tests on the straight-wing rudder propeller 200 at the same time.

[0064] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
