DETAILED DESCRIPTION
[0020] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0021] As Figure 1 As shown in the drawing, a kind of ship wake model depth setting directional control device is disclosed, including the stand 1 of installation in both ends of experimental pool, guide rail 3 is arranged between stand 1, for ship model 4 through guide rail 3 navigation between two stand 1, stand 1 still is equipped with the lifting mechanism 2 of control guide rail 3 in experimental pool depth, stand 1 is arranged at the both ends of experimental pool, and each stand 1 is the end of guide rail 3, therefore ship model 4 navigation between two stand 1, just can study the wake characteristics generated when ship model 4 navigation, guide rail 3 is to be able to guarantee the navigation direction and navigation depth of ship model 4, and guide rail 3 uses lifting mechanism 2 to control its depth in experimental pool, so that the navigation of ship model 4 in different water depth can be realized.
[0022] In the whole depth setting directional control device, guide rail 3 determines depth setting directional parameter, such as Figure 2As shown, the guide rail 3 includes a transmission wheel 9 and a guide cable, the guide cable is a closed ring shape and is sleeved on the transmission wheel 9 at both ends to form an upper guide rail 7 and a lower guide rail 8, the ship model 4 is installed with a sliding connection frame 5 on both sides, the sliding connection frame 5 on each side is in sliding connection with the upper guide rail 7 and the lower guide rail 8, and after the sliding connection frame 5 is connected with the lower guide rail 8, the lower guide rail 8 is pushed to tilt away from the upper guide rail 7. In order to ensure that the ship model 4 can sail on the guide rail 3, although the ship model 4 itself has a certain buoyancy, the guide rail 3 also needs to have a certain bearing capacity, and the cost of pursuing a longer guide rail 3 is lower, so the guide cable is used as the body of the guide rail 3, the guide cable cooperates with the transmission wheel 9, a guide cable connected at the head and tail is sleeved on the two transmission wheels 9 to form the upper guide rail 7 and the lower guide rail 8, the upper guide rail 7 and the lower guide rail 8 are essentially a guide cable, only the transmission wheel 9 changes the bending direction, so that a guide cable becomes two, improving its bearing capacity, and the sliding connection frame 5 is connected with the upper and lower guide rails, so the weight of the ship model 4 is evenly distributed, in order to maintain the straightness of the upper and lower guide rails, the sliding connection frame 5 in contact with the lower guide rail 8 can push the lower guide rail 8 to tilt away from the upper guide rail 7, which will further tighten the upper guide rail 7, ensuring the straightness of the upper guide rail 7.
[0023] As shown in Figure 3 The sliding connection frame 5 includes an upper sliding frame 11 and a lower sliding frame 12 fixed on the mounting plate 10, the upper sliding frame 11 is fixed on the adjusting seat 15, the mounting plate 10 is provided with a sliding groove 14, the adjusting seat 15 is in sliding connection with the sliding groove 14, the top of the adjusting seat 15 is also provided with an adjusting bolt 16 for controlling the upward and downward movement of the adjusting seat 15, the upper sliding frame 11 is in sliding connection with the upper guide rail 7, and the lower sliding frame 12 is in sliding connection with the lower guide rail 8, in order to facilitate the installation of the two sliding frames on the guide rail, the upper sliding frame 11 is designed to be adjustable, the distance between the upper sliding frame 11 and the lower sliding frame 12 is first controlled to be larger, so that the lower sliding frame 12 can be placed on the lower guide rail 8, and then the upper sliding frame 11 is controlled to move downward by the adjusting bolt 16, so as to reduce the distance between the two sliding frames, so that the upper sliding frame 11 is also placed on the surface of the upper guide rail 7, and the connection between the sliding connection frame 5 and the guide rail 3 is completed.
[0024] As mentioned above, the lower guide rail 8 will be supported to tilt, so the sliding wheel 13 is installed on the lower sliding frame 12, the sliding wheel 13 extends out of the lower sliding frame 12 and is in sliding contact with the lower guide rail 8, the sliding wheel 13 is used as a structure for supporting the outward tilt of the lower guide rail 8, reducing the wear of the lower guide rail 8, as shown in Figure 2 and Figure 3It can be seen that the upper slide 11 is a straight bar type, so the contact area with the straight upper guide rail 7 is large, it is not easy to fall off, and it will not wear the upper guide rail 7. If the lower slide 12 is also a straight bar type, the inclined lower guide rail 8 will wear the lower slide 12 at both ends, so the lower slide 12 is not used as the main structure to bear gravity, and the contact area does not need to be considered. Only the sliding wheel 13 needs to be set as a structure to reduce wear.
[0025] As shown in Figure 4 One end of the guide rail 3 is also provided with a tensioning mechanism 6, which includes a tensioning cylinder 18 and a moving base 19. The transmission wheel 9 is installed on the moving base 19 and is pushed by the tensioning cylinder 18 to move away from the opposite transmission wheel 9. Since the guide rail 3 adopts a cable guide structure, a tensioning mechanism 6 is needed to ensure that the cable is in a tight state. The tensioning mechanism 6 uses a tensioning cylinder 18 to push the transmission wheel 9 in the opposite direction to pull apart the distance between the two transmission wheels 9 on the same guide rail 3, achieving the effect of tensioning. The transmission wheel 9 is installed on the moving base 19, and the moving base 19 is slidingly installed on the slide rail 20 of the lifting frame 17, ensuring the smoothness of the moving base 19.
[0026] As shown in Figure 5 The lifting mechanism 2 includes a lifting frame 17 and a traction rope 21. The guide rail 3 is installed on the lifting frame 17, and the bottom end of the traction rope 21 is connected to the lifting frame 17. The top end passes through a plurality of fixed pulleys 22 and is connected to a winding drum 23. The winding drum 23 is driven by a lifting motor 24. The lifting mechanism 2 uses a rope lifting method. The lifting frame 17 adjusts the up-down position by pulling the traction rope 21. The traction rope 21 is wound on the winding drum 23. As the lifting motor 24 drives the winding drum 23 to wind and unwind the rope, the effect of adjusting the lifting of the lifting frame 17 is achieved. After adjusting the height of the lifting frame 17, the height needs to be locked. The lifting frame 17 is slidingly connected to the stand 1 through a connecting plate 27. A plurality of positioning holes 25 are formed on the stand 1. A fixed pin 26 is installed on the connecting plate 27. The fixed pin 26 is fixed with the positioning hole 25. Different depths are locked by inserting the fixed pin 26 into the corresponding positioning hole 25. In this way, the stability of the guide rail 3 can be ensured when the lifting frame 17 is fixed.
