[0047] In the embodiment, as shown in Figure 2 The wave pressing mechanism 103 includes a bottom plate 1031, and a front plate 1032 and a rear plate 1033 are respectively arranged on the two sides of the bottom plate 1031 in a slanting manner.

Specifically, a part of the straight wing rudder paddle 200 is located on the upper side of the clearance hole 1034, and the paddle blade of the straight wing rudder paddle 200 is located below the clearance hole 1034.

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

[0049] In the embodiment, as shown in Figure 3 The sensor includes a torque sensor 105. One end of the torque sensor 105 is connected with the motor 104, and the other end of the torque sensor 105 is connected with the input shaft of the straight wing rudder paddle 200 through a shaft coupling 106. The motor 104 is used to drive the straight wing rudder paddle 200 to move through the torque sensor 105.

[0050] Specifically, the torque sensor 105 can obtain corresponding data in real time during the process that the straight wing rudder paddle 200 advances in the wave pool. After the data is collected, the performance of the straight wing rudder paddle 200 can be analyzed.

[0051] In the embodiment, as shown in Figure 3 and Figure 4As shown, the sensor further comprises a six-component force sensor 108, one end of the six-component force sensor 108 is connected with a lower cover 109, the lower cover 109 is used to be connected with the housing 201 of the straight wing rudder paddle 200, the other end of the six-component force sensor 108 is connected with the bottom end of the upper support 107, the motor 104 and the torque sensor 105 are fixed on the upper support 107, for example, the motor 104 is arranged at the top of the upper support 107, the torque sensor 105 is arranged below the motor 104 and connected with the upper support 107, the upper support 107 is connected with an upper cover 112 through a connecting disc 110, and the motor 104 and the torque sensor 105 are located inside the upper cover 112. The upper cover 112 can protect the motor 104 and the torque sensor 105. The upper cover 112 is cylindrical as a whole and can be divided into upper and lower parts, the upper part has a smaller diameter, and the lower part has a larger diameter.

[0052] Specifically, when the straight wing rudder paddle 200 works in water, the straight wing rudder paddle 200 will be subjected to external force, since one end of the six-component force sensor 108 is connected with the lower cover 109, and the lower cover 109 is connected with the housing 201 of the straight wing rudder paddle 200, the working straight wing rudder paddle 200 can be measured through the six-component force sensor 108 to obtain corresponding mechanical data.

[0053] On the basis of the above, the upper cover 112 is floatingly connected with the frame body 101, that is, the upper cover 112 can move relative to the frame body 101.

[0054] Specifically, as shown in Figure 1 and Figure 5 As shown, the frame body 101 is provided with a first sliding rail assembly 113, which can be composed of sliding rails and sliding blocks.

The mechanical sensor 115 can be a tension sensor or the like.

[0055] Specifically, when the straight wing rudder paddle 200 works in water, the straight wing rudder paddle 200 will be subjected to external force, which will cause the upper cover 112 to move, and the movement of the upper cover 112 will drive the moving plate 114 to move along the first sliding rail assembly 113, since the two sides of the moving plate 114 are connected with the mechanical sensors 115, corresponding data can be detected through the mechanical sensors 115.

[0056] In one of the embodiments, the moving plate 114 is provided with a plurality of guide sleeves 116, each of which is provided with a guide column 117 connected to the upper end of the upper cover 112, and the frame body 101 above the upper cover 112 is further provided with a second sliding rail assembly 119 which can be composed of sliding rails and sliding blocks.

[0057] Specifically, the lead screw mechanism 118 can be a trapezoidal lead screw mechanism 118. The trapezoidal lead screw mechanism 118 has good self-locking ability, which is conducive to ensuring that the lead screw mechanism 118 can be self-locked after being adjusted in place and will not move unexpectedly.

[0058] Specifically, the lead screw mechanism 118 of the present application can be operated manually. That is, the operator can stand at a high place and rotate the lower lead screw mechanism 118 by using a tool.

[0059] Specifically, since the depth of water in each pool is different, the size of each straight wing rudder paddle 200 is also different, in order to facilitate the adjustment of the up-down height position of the straight wing rudder paddle 200 and make the paddle blade of the straight wing rudder paddle 200 located at a predetermined position in the water, the present application is provided with the above-mentioned lead screw mechanism 118. The height of the upper cover 112 can be adjusted through the lead screw mechanism 118, and since the upper cover 112 is connected to the straight wing rudder paddle 200 through other components, the height of the straight wing rudder paddle 200 will also be adjusted accordingly after the height of the upper cover 112 is adjusted. In this way, flexible and accurate adjustment of the height of the straight wing rudder paddle 200 can be achieved.

[0060] Further, the present application is provided with the second sliding rail assembly 119, the support frame 120 is arranged on the second sliding rail assembly 119 and can move along the second sliding rail assembly 119, and the arrangement direction of the second sliding rail assembly 119 is consistent with that of the first sliding rail assembly 113, which makes the support frame 120 also move correspondingly when the upper cover 112 moves, and the lead screw mechanism 118 on the support frame 120 will not interfere with the movement of the upper cover 112.

[0061] It should be noted that the straight wing rudder propeller testing device of the present application is connected with the straight wing rudder propeller 200 in specific use, that is, the straight wing rudder propeller 200 is connected with the lower housing 109, and at the same time, the input shaft of the straight wing rudder propeller 200 is connected with the torque sensor 105 through the shaft coupling. The propeller blade of the straight wing rudder propeller 200 is located below the accommodation hole 1034 of the bottom plate 1031 of the wave compression mechanism 103.

The towing tank includes a trailer, a pool and a wave generator, the trailer connecting part 102 of the frame body 101 is connected with 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, which uses the straight wing rudder propeller testing device described above, and the straight wing rudder propeller 200 is connected with the straight wing rudder propeller testing device, and also includes a towing tank, which includes a trailer, a pool and a wave generator, the trailer connecting part 102 of the frame body 101 is connected with the trailer, and the straight wing rudder propeller 200 is located in the pool, the motor 104 drives the straight wing rudder propeller 200 to rotate, and the trailer drives the frame body 101 to move, so that the straight wing rudder propeller 200 moves in the pool with waves during rotation.

[0063] In the above testing 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 property data of the straight wing rudder propeller 200 in operation can be obtained through the torque sensor 105, the six-component force sensor 108 and the tension sensor. The straight wing rudder propeller 200 can be tested for multiple mechanical properties at the same time.

[0064] The above embodiments only express several embodiments of the present application, which are described in detail and specifically, but cannot be understood as a limitation on the scope of the patent.
