The imitation mechanism 2 includes a mounting base 21 arranged on the trolley body 1, an imitation motor 22 connected to the mounting base 21, a connecting component 23 driven and connected to the imitation motor 22, and a plurality of simulation boards 24 connected to the connecting component 23. The connecting component 23 can rotate under the drive of the imitation motor 22.

[0033] It can be understood that the vehicle body 1 can be an unmanned vehicle, and a plurality of guide wheels 11 are installed at the bottom of the vehicle body 1 so that the vehicle body 1 can move in different directions. The imitation mechanism 2 and the imitation climbing mechanism 3 can be detachably connected to the vehicle body 1, and the setting height of the imitation mechanism 2 is higher than the setting height of the imitation climbing mechanism 3. The multiple simulation boards 24 can rotate with the connection component 23 under the drive of the imitation motor 22, and cooperate with the movement of the vehicle body 1. The multiple simulation boards 24 form an imitation simulation whole. The imitation simulation whole is spherical in this embodiment, and the simulation board 24 is preferably a nylon board.

[0034] In actual operation, the imitation simulation can be adjusted to a specified height, and the simulation can be suspended at any angle by controlling the rotation of the imitation motor 22, so as to adjust the spatial position of the imitation simulation according to different application scenarios. In the working process, after adjusting the spatial position of the imitation simulation, the imitation motor 22 can be used to lock and fix the position of the imitation simulation, and the vehicle body 1 can be controlled to simulate walking and running at a specified speed to cross the gravel road surface, thereby completing the walking and running movements of a simulated person.

[0035] like Figure 5 As shown, the connection assembly 23 includes a mounting plate 231 connected to the output end of the imitation motor 22, a connecting rod 232 connected to the mounting plate 231, and a connecting block 233 connected to the connecting rod 232.

The adjustment holes 2311 are arranged at intervals along the length direction of the mounting plate 231, so that the connecting rod 232 can be connected to different adjustment holes 2311 to adjust the height of the imitation simulation as a whole. The mounting plate 231 and the connecting rod 232, and the connecting rod 232 and the connecting block 233 can be connected by bolts, and the connecting rod 232 and the mounting plate 231 are arranged vertically.

[0036] like Figure 7 As shown, the connection block 233 is provided with a plurality of insertion slots 2331 for inserting the simulation board 24, and the plurality of simulation boards 24 are inserted into the connection block 233 at a preset angle, and the plurality of simulation boards 24 are arranged at intervals along the central axis of the connection block 233 to form a spherical structure, and the diameter of the spherical structure is about 30 mm.

In the specific operation process, the first contact switch 25 and the second contact switch 26 are used as the limit of the mounting plate 231. In the process of simulating jumping, the reciprocating rotation movement of the mounting plate 231 can be controlled by controlling the imitation motor 22. At this time, the trolley body 1 is moved to the middle position of the gravel road. After the alarm is eliminated, the mounting plate 231 is controlled to rotate. The mounting plate 231 can be rotated clockwise starting from the first contact switch 25 until the second contact switch 26 is turned off, and then the mounting plate 231 is rotated counterclockwise starting from the second contact switch 26 until the first contact switch 25 is turned off, so as to simulate a person jumping through.

[0038] Among them, the device for testing the effectiveness of nuclear power security systems can also be used as a patrol device. When the device for testing the effectiveness of nuclear power security systems is used as a patrol device, the device for testing the effectiveness of nuclear power security systems also includes a camera 4, which can obtain an image of the application environment on site and can be used for daily patrol work. The camera 4 is specifically installed on the mounting base 21 in this embodiment. If the device for testing the effectiveness of nuclear power security systems is only used to test microwave detection equipment, the camera 4 may not be installed.

[0039] like Figure 1 and Figure 6 As shown, the imitation climbing mechanism 3 includes an imitation climbing control component 31 , a limit fixing component 32 arranged on the trolley body 1 , and an imitation climbing simulation ball 33 installed on the limit fixing component 32 and connected to the imitation climbing control component 31 . The imitation climbing control component 31 includes a connecting base plate 311 arranged on the trolley body 1, a cable reel positioning seat 312 connected to the connecting base plate 311, a cable reel 313 arranged in the cable reel positioning seat 312 and rotatably connected to the cable reel positioning seat 312, and a cable reel driving motor 314 arranged on the cable reel positioning seat 312 and drivingly connected to the cable reel 313. The imitation climbing simulation ball 33 is connected to the cable reel 313 through a winding wire, and the moving speed of the imitation climbing simulation ball 33 can be controlled by the cable reel driving motor 314. The output end of the cable reel driving motor 314 can be connected to the cable reel 313 through a gear, so that the cable reel driving motor 314 can drive the cable reel 313 to rotate. The cable reel driving motor 314 is preferably a harmonic motor.

[0040] like Figure 4As shown, the limiting fixing assembly 32 includes a fixing rod 321 connected to the trolley body 1, a positioning plate 322 connected to the fixing rod 321, and a guide support assembly 323 connected to the positioning plate 322 and used to limit and guide the climbing simulation ball 33. In this embodiment, the number of the guide support assemblies 323 is two, which are used to provide support and guidance for the movement of the climbing simulation ball 33.

[0041] For example Figure 4 As shown, the guide support assembly 323 includes a first support rod 3231, a second support rod 3232 and a connecting piece 3233. The first support rod 3231 is rotatably connected to the positioning plate 322, and the second support rod 3232 is rotatably connected to the positioning plate 322. The first support rod 3231 is arranged closer to the positioning plate 322 than the second support rod 3232. The first support rod 3231 and the second support rod 3232 are connected by the connecting piece 3233. The hinge point between the first support rod 3231 and the positioning plate 322 is consistent with the hinge point between the second support rod 3232 and the positioning plate 322. The connecting piece 3233 is provided with There is a first hole 32331 connected to the first support rod 3231 and a second hole 32332 connected to the second support rod 3232. The first support rod 3231, the second support rod 3232 and the positioning plate 322 can be fixed and locked by a locking nut, and the connecting piece 3233 further strengthens the connection between the first support rod 3231 and the second support rod 3232. The second support rod 3232 has a certain inclination angle relative to the positioning plate 322, and the inclination angle can be adjusted according to actual applications to provide different motion trajectories for the crawling simulation ball 33 during movement, thereby increasing the diversity of test scenarios.

[0042] The position limiting fixing assembly 32 further includes a third contact switch 324 mounted on the positioning plate 322 . When the crawling simulation ball 33 reaches the sensing position of the third contact switch 324 , the third contact switch 324 can sense and send a signal to the winding drive motor 314 .

[0043] In the specific operation process, when it is necessary to simulate the crawling movement, the trolley body 1 stops at the first measuring point, and the electromagnetic clutch is disconnected, that is, the winding drive motor 314 is in an inoperative state, and the crawling simulation ball 33 is lowered due to gravity. At this time, the trolley body 1 is controlled to move to the second measuring point, and the electromagnetic clutch is powered on. The winding drive motor 314 is used to control the winding drum 313 to rotate, and the winding wire also rotates at this time, and the crawling simulation ball 33 is retracted to the side close to the trolley body 1 at a specified speed. After the crawling simulation ball 33 approaches this third contact switch 324, the third contact switch 324 transmits a limit signal to the winding drive motor 314, and the winding drive motor 314 stops moving and is electrically locked. The above operation process realizes the simulated crawling function of the crawling mechanism 3.

[0044] In general, the device for testing the effectiveness of the nuclear power security system can simulate human movements such as running, jumping, walking, and climbing by setting up the imitation mechanism 2 and the imitation climbing mechanism 3, and can realize the alarm effectiveness test of all microwave detection equipment in the plant one by one, so as to carry out more comprehensive and reasonable testing work, improve work efficiency, reduce labor costs, and realize unmanned autonomous testing functions in the protected area.

It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model.
