[0022] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0023] Example 1

[0024] like Figure 1-Figure 4 As shown, a landscaping tree shaking demonstration device for simulating earthquake scenes mainly includes a base 1, a shaking device 2, and a fixing device. The top of the base 1 is provided with a shaking device 2, and the top of the shaking device 2 is provided with a fixing device. The shaking device 2 can drive the fixing device to swing and vibrate on a plane, and the fixing device can fix the landscaping tree.

[0025] The base 1 includes a fixed plate, and a shaking device 2 is fixed above the fixed plate. The shaking device 2 includes a servo motor 201, a swing platform 202, a vibrator 203, a bearing seat 204, and a driving cam 205.

[0026] The servo motor 201 is arranged at one end of the base 1, the output end of the servo motor 201 is connected to the driving cam 205, the driving cam 205 is connected to the bottom of the swing platform 202, the bottom of the bearing seat 204 is fixed on the base 1, the swing platform 202 is fixed on the top of the bearing seat 204, and the top of the swing platform 202 is provided with a sleeve 3 and a vibrator 203. The sleeve 3 is arranged in the middle of the swing platform 202, and the vibrator 203 is arranged on one side of the swing platform 202 and is not connected to the sleeve 3.

[0027] The bearing seat 204 is composed of two fixed frames in the shape of right-angled steps. The right-angled steps are arranged above the base 1 at one end. A swinging platform 202 is connected in the middle of the interval between the two right-angled steps. An extension plate is arranged on the side of the swinging platform 202 where the sleeve 3 is not arranged. A hole is arranged in the middle of the extension plate to cooperate with the driving cam 205. The driving cam 205 is connected to the extension plate to control the swinging of the swinging platform. A hole is arranged on the top of the right-angled step. An axis is arranged at one end of the extension plate close to the swinging platform 202. The axis cooperates with the hole to limit the swinging platform 202 on the bearing seat 204. The swinging platform 202 swings around the bottom of the extension plate as a fixed point.

[0028] The fixing device comprises a sleeve 3, which is a hollow cylinder with four reinforcing ribs arranged on the outside, and the sleeve 3 is fixed to the top of the swing platform 202 by welding. The landscaping tree is fixed in the sleeve 3 by sliding connection.

[0029] The control system controls the operating parameters of the shaking device 2. As an embodiment, the control system adopts an infrared remote control system.

[0030] Working principle: before use, the landscaping tree needs to be fixed inside the sleeve 3, and the servo motor 201 and the vibrator 203 need to be connected to the power supply. During the demonstration, the intensity of the seismic wave of the simulated earthquake is low, and the infrared remote control system controls the operation of the servo motor 201. The servo motor 201 first rotates slowly forward and reverse. The servo motor 201 drives the driving cam 205 to operate, so that the sleeve 3 drives the landscaping tree to shake slightly, and the vibrator 203 vibrates slightly. As the intensity of the seismic wave of the simulated earthquake gradually increases, the infrared remote control device controls the operating power of the servo motor 201 and the vibrator 203 to continue to increase with the seismic wave. Produce an earthquake effect. After the simulated earthquake ends, the infrared remote control system controls the operation of the servo motor 201 and the vibrator 203 to shut down. The sleeve 3 swings at a rate of 1-50r / min and a swing angle of 0°-10°.

[0031] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments.
