DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] A vertical rotor tester bird impact test launching device is arranged on an upper cover 25 of a vertical rotor tester, and includes a control system 1, a projection device 2, a blocking mechanism 3 and a barrel 4. The projection device 2 includes an actuating mechanism and a bird body positioning structure.

[0023] The barrel 4 is vertically arranged on one side of the upper portion of the upper cover 25 of the vertical rotor tester, and the axis of the barrel 4 passes through the rotor blade of the vertical rotor tester. The bird body positioning structure is fixedly connected to the upper portion of the barrel 4, and the bird body positioning structure is internally provided with a bird body 24 loading cabin coaxially arranged with the barrel 4. The bird body 24 is arranged in the bird body 24 loading cabin. The actuating mechanism is arranged below the bird body positioning structure and connected to the barrel 4. The actuating mechanism is provided with a supporting plate 5 corresponding to the position below the bird body 24 loading cabin. Before the bird body 24 is launched, the actuating mechanism can drive the supporting plate 5 to move to the position below the bird body 24 loading cabin to support the bird body 24. When the bird body 24 is launched, the actuating mechanism can drive the supporting plate 5 to move out from the position below the bird body 24 loading cabin. The control system 1 is electrically connected to the actuating mechanism.

[0024] The control system 1 is electrically connected to the actuating mechanism and can control the actuating mechanism to drive the supporting plate 5 to move. The blocking mechanism 3 is arranged on the barrel 4 and can block the bird body 24 entering the barrel 4. The lower end of the barrel 4 is sealingly connected to the upper cover 25 of the vertical rotor tester. The upper cover 25 of the vertical rotor tester is provided with a through hole corresponding to the position of the barrel 4, so that the bird body 24 can continue to fall.

[0025] Through the above design, a vertical bird body 24 launching structure is formed. After the control actuating mechanism is moved out from below the bird body 24 loading cabin, the bird body 24 freely falls under gravity and falls through the through hole to the rotating blade to complete the bird impact test in the single or multiple blade rotating state. The blocking mechanism 3 can effectively prevent the test cost caused by accidental falling of the bird body 24 before the release instruction is issued, and solves the problem of blocking the bird body 24 from accidentally falling.

[0026] Since the bird body 24 is in a free and relaxed state before release, there is no extra object participating in the impact with the bird body 24, and the problem of bird body 24 staying before vertical release of the bird body 24 is solved. Since the bird body 24 is in a free fall state for bird impact test, the speed of the bird body 24 can be calculated very accurately, and the problem of the release mechanism moving quickly and affecting the speed of the bird body 24 is solved.

[0027] And the different positions of the barrel 4 and the vertical rotor tester upper cover 25 can be connected to realize different impact point test capability.

[0028] The functions and effects of each part are described as follows:

[0029] I. Control system design

[0030] The control system 1 is an electric control system for issuing control instructions to the actuating mechanism, including a local control cabinet 22 and a remote control computer 23. The remote control computer 23 is used to issue control instructions to the local control cabinet 22, and the local control cabinet 22 controls the specific actions of the actuating mechanism according to the control instructions.

[0031] The actuating mechanism is provided with pressure, position and other sensors. The signals collected are transmitted to the remote control computer 23 through the local control cabinet 22. The remote control computer 23 is provided with control software. The signals collected by the sensors are converted into data and displayed in the control software, which is used to judge whether the blocking mechanism 3 is in place, whether the bird body 24 is in place, whether the loading mechanism rear cover is installed in place, etc. Other conditions that cannot be directly judged in the control system 1 and need to be confirmed before launching can be added to the judgment combination of the preset conditions by the operator.

[0032] The operation interface is displayed in a graphical interface, and various condition judgments and button states are distinguished by obvious colors.

[0033] To ensure operation safety, a manual air release valve and an emergency stop button connected to the actuating system are provided on site. The control system 1 can realize local / remote control switching, and the overall process is as follows: Figure 2As shown, after the actuation mechanism is ready, the bird body 24 is loaded, and the high-speed camera is prepared. Then the tester is started, the control system 1 controls the bird body 24 to launch, and at the same time controls the high-speed camera to trigger and record the launch of the bird body 24 until the bird body 24 hits the rotating blade and stops.

[0034] II. Bird Body Positioning Structure

[0035] like Figure 3 As shown, the bird body 24 positioning mechanism includes an upper shell 6, an outer shell 7, a middle shell 8, and an inner shell 9. The upper shell 6 and the inner shell 9 are arranged vertically correspondingly, and the outer shell 7, the middle shell 8, and the inner shell 9 are coaxially arranged internally and externally. The upper shell 6 is a hollow cylindrical structure, and the loading compartment of the bird body 24 is located inside the upper shell 6. The outer shell 7, the middle shell 8, and the inner shell 9 are all hollow cylindrical structures. The bottom of the upper shell 6 is provided with a partition that is fixedly connected to the top of the outer shell 7 and the middle shell 8. The inner shell 9 has a central cavity that communicates with the loading compartment of the bird body 24. The space between the inner shell 9 and the middle shell 8 is a receiving cavity, and the space between the middle shell 8 and the outer shell 7 is an outer cavity. The actuating mechanism communicates with the receiving cavity to expand the volume of the pressure chamber outside the actuating mechanism, reduce the pressure drop in the cavity when the piston 17 moves, and maximize the movement speed of the piston 17.

[0036] A linkage mechanism supporting the bird 24 is provided between the central cavity and the loading compartment of the bird 24. The support plate 5 is connected to the end of the linkage mechanism, which is controlled by an actuation mechanism. The linkage mechanism includes a telescopic rod 10, a hinge seat 11, and a swing plate 12. The lower end of the telescopic rod 10 is connected to the output end of the actuation system. The hinge seat 11 is located on the inner wall of the middle shell 8. The swing plate 12 is horizontally positioned when the bird 24 is not launched. One end of the swing plate 12 is hinged to the hinge seat 11, and the other end is connected to the support plate 5. A swing groove is formed inside the swing plate 12 along its length. A connecting post 13 is provided at the upper end of the telescopic rod 10. The connecting post 13 is slidably connected in the swing groove and can rotate within the swing groove.

[0037] The actuation mechanism drives piston 17 and piston rod 17 to move tray 5 between the central cavity and the receiving cavity. When tray 5 is in a horizontal position, the bird body 24 is located in the bird body 24 loading compartment above tray 5. During "launch", tray 5 is rapidly retracted and enters the receiving compartment under the action of the actuation mechanism, and the bird body 24 falls freely. The upper part of the bird body 24 loading compartment is designed with a sealed door that is easy to open and close for loading the bird body 24 before launch.

[0038] III. Actuating Mechanism

[0039] like Figure 4As shown, the actuating mechanism includes a vacuum venting cavity 14, a driving pressure cavity 15, a piston pressure cavity 16 and a piston 17. The bird 24 can pass through the barrel 4 and the central cavity. The piston pressure cavity 16 is inflated to push the piston 17 to move upward, push the swing plate 12 upward, keep the support plate 5 horizontal and enable the support plate 5 to support the bird 24. When the bird 24 is released, the gas in the piston pressure cavity 16 is discharged into the vacuum venting cavity 14, the piston 17 moves downward under the driving of the gas in the driving pressure cavity and moves the support plate 5 into the storage cavity, and the bird 24 falls freely.

[0040] The driving pressure cavity is in communication with the cavity outside the bird 24 positioning mechanism, which is used to expand the cavity volume, reduce the pressure drop in the cavity when the piston 17 moves, and maximize the speed of the piston 17. The piston pressure cavity 16 is correspondingly arranged inside the driving pressure cavity. The driving pressure cavity and the piston pressure cavity 16 are connected to the gas source. The upper end of the piston pressure cavity 16 is in communication with the driving pressure cavity, the lower end of the piston pressure cavity 16 is in communication with the vacuum pressure cavity, the piston 17 is arranged in the piston pressure cavity 16, and the upper end of the piston 17 is connected to the telescopic rod 10. The lower vacuum venting cavity 14 is used to receive the compressed air discharged from the piston pressure cavity 16, so as to reduce the pressure in the piston pressure cavity 16 to the lowest and improve the moving speed of the piston 17. If necessary, the lower vacuum venting cavity 14 can be in communication with the vacuum chamber of the vertical rotor tester.

[0041] Four, barrel

[0042] The barrel 4 is divided into an upper barrel and a lower barrel. The effective barrel 4 length can be changed in size according to actual needs, and the caliber of the barrel 4 can be adjusted. A connecting body is specially designed at the connection between the barrel mouth and the original opening of the vertical rotor test system upper cover 25, which is used for docking conversion and sealing between different interface sizes. Sensor mounting holes are designed on the connecting body, which are used to measure the speed of the bird 24 when passing through and detect whether the bird 24 passes through. The barrel 4 structure is as shown in Figure 5 A sealing adapter structure 26 is arranged between the barrel 4 and the upper cover 25, as shown in Figure 6 The middle part of the sealing adapter structure 26 is in communication with the barrel 4 for the bird 24 to pass through, and the two sides of the sealing adapter structure 26 extend out to be sealingly connected with the upper cover 25.

[0043] Five, blocking mechanism

[0044] In order to prevent the projectile from entering the vacuum chamber before the target moment, a blocking mechanism 3 is designed at the barrel mouth. The structure is as shown in Figure 5 The blocking plug-in plate 20 is inserted into the barrel 4 to prevent the projectile from falling into the vacuum chamber due to accidental circumstances. Before the bird 24 is released, the blocking plug-in plate 20 is withdrawn from the barrel 4 under the driving of the external electric push rod and the push-pull rod 21. The bird loading chamber is provided with a position sensor for identifying whether the bird 24 is in the position to be launched. There is a gap between the upper barrel and the lower barrel, and the blocking mechanism 3 is arranged at the joint of the upper barrel and the lower barrel.

[0045] The blocking mechanism 3 comprises a blocking box 18, a slide 19, an insertion plate 20, a push-pull rod 21 and an electric push rod.

[0046] The blocking box 18 is horizontally connected between the upper barrel and the lower barrel, the slide 19 is horizontally arranged in the blocking box 18, and the push-pull rod 21 is horizontally slidably arranged in the slide 19; one side of the insertion plate 20 is fixedly connected with the push-pull rod 21, and the other side is horizontally inserted into the gap between the upper barrel and the lower barrel; the electric push rod is arranged outside the blocking box 18 and connected with the push-pull rod 21. When the electric push rod is retracted, the insertion plate 20 can be pulled out of the upper barrel and the lower barrel through the push-pull rod 21, and when the electric push rod is extended, the insertion plate 20 can be pushed into the upper barrel and the lower barrel through the push-pull rod 21, so as to realize the closing function.

[0047] The overall principle is shown in Figure 1 Before launching, compressed air is filled in the actuator, the actuator piston 17 reaches the designated position, and the detachable support plate 5 of the bird body 24 positioning mechanism is driven by the rod of the actuator piston 17 to reach the working position. After the bird body 24 is loaded, the launching is prepared. When the vacuum chamber of the vertical rotor tester is vacuumized, the barrel 4 and the inside of the bird body 24 positioning mechanism are also vacuumized. When the rotor reaches the predetermined rotating speed, the control system 1 sends a launching instruction, the actuator piston pressure cavity 16 discharges compressed air, the piston 17 moves quickly under the action of the compressed air in the driving pressure cavity 15 and drives the bird body 24 support plate 5 to move, the bird body 24 accelerates under the action of gravity and collides with the rotating blades. In an emergency, the emergency stop button is pressed, the blocking mechanism is closed, and the control software enters the emergency program.

[0048] Finally, it should be noted that: the drawings of the disclosed embodiments only involve the structures involved in the disclosed embodiments, other structures can refer to the general design, and in the case of no conflict, the same embodiments and different embodiments of the present application can be combined with each other;

[0049] Finally, the above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
