A conical safety cover is fitted on the top surface of the test box body. Pulley traction modules are evenly distributed at intervals in the circumferential direction on the top surface of the test box body. Each pulley traction module is respectively connected to a load module and a collision module. The load module is installed on the ground foundation outside the test box body, and a release module is installed between the load module and the outer wall surface of the test box body. A ground fence is installed on the ground foundation outside the load module. A plurality of guiding modules are installed on the inner wall surface of the test box body. A collision module is arranged at the lower position inside the test box body, and the outside of the collision module is in contact with the guiding modules. A model placement module is fixedly installed in the test box body and is located above the collision module, and is concentric with the test box body and the collision module. A model body is installed in the middle of the model placement module, and the model body corresponds to the collision module. A measurement module is also installed on the ground foundation.

[0007] As a further improvement of the above technical solution:

[0008] The test box body has an integral structure.

[0009] The structure of the test box body is as follows: it includes a box body main body with a thin-walled hollow cylinder structure. On the inner wall surface of the box body main body, positioning strips matching the model placement module are distributed at intervals. On the outer wall surface of the box body main body and staggered with the positioning strips, mounting blocks are arranged. On the top surface of the mounting blocks, a pulley traction module is fixedly installed. On the wall surface of the box body main body, a plurality of long strip-shaped holes are opened, which are used for installing plexiglass observation windows during ejection under water environment.

[0010] The cross-section of the positioning strip has a "T" - shaped structure.

[0011] The structure of the pulley traction module is as follows: it includes a bottom plate fixed to the test box body. On the bottom plate, a pulley mounting seat is fixed. At both ends of the pulley mounting seat, pulleys are symmetrically installed. A traction steel wire rope is installed in cooperation with the pulleys.

At both ends of the pulley mounting seat 301, pulleys 303 are symmetrically installed. A traction steel wire rope 304 is fitted on the pulleys 303. One end of the traction steel wire rope 304 is connected to the load module 5, and the other end of the traction steel wire rope 304 is connected to the collision module 6.

[0041] The bottom plate 302 is made of a thin rectangular plate, which is more stable in fixation. The pulley mounting seat 301 is composed of two spaced "T" shaped plates, and the installation of the pulleys 303 is convenient.

On a single tray 503, a wire rope clamp 501 is installed, and the wire rope clamp 501 is fixedly connected to the traction steel wire rope 304 of the pulley traction module 3. Weights 502 are installed on the trays 503, and an electromagnetic chuck 401 is installed on the tray 503 beside the weights 502.

[0046] The tray 503 is in a fan-shaped structure, which has better stability, and it is convenient for the weights 502 and the electromagnetic chuck 401.

[0047] The specific structure and functions of the object ejection test device based on the conversion and utilization of gravitational potential energy and collision kinetic energy of the present invention are as follows:

[0048] The present invention mainly relates to the ejection acceleration, speed, etc. of a model, and can be ejected in a water environment.

[0049] It mainly includes: a test box body 1, a safety cover 2, a pulley traction module 3, a release module 4, a load module 5, a collision module 6, a guiding module 7, a model placement module 8, a model body 9, a ground fence 10, a measurement module 11, a ground foundation 12, etc.

[0050] All modules are installed or arranged around the test box body 1. Among them: the load module 5, the release module 4, the ground fence 10, and the measurement module 11 are installed outside; the pulley traction module 3 and the safety cover 2 are installed on the upper part; and the rest are installed or arranged inside.

[0051] The load module 5 is connected to the collision module 6 through a steel wire rope on the pulley traction module 3 and is hung on both sides of the pulley traction module 3. When the release module 4 is powered off, the load module 5 freely falls, driving the collision module 6 to quickly rise along the guiding module 7 and collide with the model placed on the model installation module, so that the model is quickly ejected. The measurement module 11 is used to obtain parameters such as the acceleration and speed of the model during ejection and flight.

[0052] An acrylic observation window is opened on the test box body 1, through which the entire ejection process can be directly observed. The rubber pad plays a role in vibration isolation and buffering for the rapidly falling weight 502. The lead-out sleeve on the model installation module plays a role in centering and guiding, preventing the model from tilting and being non-coaxial during placement and ejection. The safety cover 2 controls the ejected model within a safe range.

[0053] During the actual working process, the ejection test is completed through the following process:

[0054] (1). The safety cover 2 is fixed on the upper part of the test box body 1. The release module 4 is fixed outside the test box body 1, and its electromagnetic chuck 401 is in a powered-off state when not working. The weight 502 and the tray 503 are placed on the load support seat 505, and the weight 502 is fixed on the tray 503. The collision module 6 is placed on the bottom surface of the test box body 1. The pulley traction module 3 is fixed on the upper part of the test box body 1, and the two ends of its traction steel wire rope 304 are respectively connected to the weight 502 and the collision module 6. The model installation module is fixed inside the test box body 1, and the model is placed in the circular flange of the model installation module and is coaxial with the collision head on the collision module 6.

[0055] (2). The release module 4 is powered on, and the electromagnetic chuck 401 sucks up and raises the tray 503, and the weight 502 is separated from the load support seat 505.

[0056] (3). The load support seat 505 is withdrawn, and the ejection is ready.

[0057] (4). First, start the measurement module 11, then release the electromagnet chuck 401 on the module 4 to cut off the power, and the weight 502 will immediately fall freely, driving the rollers on both sides of the collision module 6 to roll upward along the guiding module 7, and the collision module 6 will rise.

[0058] (5). The weight 502 continues to fall freely, and the collision module 6 continues to rise until the collision head installed on it collides with the model.

[0059] (6). The model collides and pops out, the weight 502 falls onto the rubber pad, and the ejection ends.

[0060] The above description is an explanation of the present invention, not a limitation of the invention. For the scope defined by the present invention, refer to the claims. Any form of modification can be made within the protection scope of the present invention.
