Under the synchronous action of the axial flow fan blades, it effectively prevents dust and debris from affecting the image acquisition and detection of the camera detection device;

[0019] 2. To solve the problem that the electric cylinder is damaged or the control signal is delayed and lost when the mechanical claw works in a high-radiation environment, and the mechanical claw resets itself during the clamping process, resulting in the nuclear radiation items falling off and the nuclear radioactive substances spreading, the present application can effectively prevent the mechanical claw from resetting during the clamping process by arranging the protection component to utilize the wedge-shaped block arranged inside the slider to form a clamping connection with the fixed cone block arranged in the sliding groove. Through the continuous displacement and reset of the slider, the clamping connection between the active cone block and the wedge-shaped block and the fixed cone block can be contacted, preventing the nuclear radiation items from falling during the grasping process while realizing the grasping and placing of items by the mechanical claw;

[0020] 3.

A cleaning component 4 is arranged inside the assembly cavity 303. The plurality of clamping arms 208 can surround the periphery of the housing 301, and the housing 301 will simultaneously displace towards the inside of the assembly cavity 303 to be connected to the cleaning component 4. The cleaning component 4 can drive the housing 301 to rotate reciprocally;

[0050] The cleaning component 4 includes an assembly cylinder 409 rotatably installed inside the assembly cavity 303. Axial flow fan blades 407 are arranged on the outer wall of the assembly cylinder 409. A receiving ring 401 is installed on the outer wall of the body 1 at the top of the assembly cavity 303. The receiving ring 401 is rotatably connected to the housing 301. A plurality of air blowing holes 411 are penetrated and arrayedly installed on the outer wall of the receiving ring 401.

[0053] In order to solve the problems that in the nuclear accident emergency response work, an explosion may occur at the nuclear accident site at any time, generating explosives that may damage the camera detection device, and at the same time, a large amount of dust and debris will be generated, which will affect the image acquisition and detection of the camera detection device, resulting in the inability of the nuclear radiation detection robot to feedback the situation at the nuclear accident site to the staff, and even the nuclear radiation detection robot cannot return and is left at the nuclear accident site. In this application, by setting the grasping component 2, the mechanical claw 204 can, under the control of the rotating seat 201, the first telescopic arm 202 and the second telescopic arm 203, grasp the nuclear radioactive items at the nuclear accident site, and at the same time, the mechanical claw 204 can be controlled to displace to the outer shell 301. The clamping arm 208 forms a covering protection with the outer wall of the outer shell 301, which can prevent the explosives generated by the explosion at the nuclear accident site from damaging the detection component 3. At the same time, the cleaning component 4 is used to clean the outer shell to prevent dust and debris from contaminating the outer shell 301, resulting in the image acquisition and detection of the detection component 3 being affected. The mechanical claw 204 can drive the outer shell 301 to displace into the assembly cavity 303 to cooperate with the cleaning component 4, thereby driving the outer shell 301 to rotate reciprocally, improving the detection range of the detection component 3. At the same time, the clamping arm 208 fits with the outer wall of the outer shell 301. A rubber strip is arranged on the surface where the clamping arm 208 fits with the outer shell 301. Under the reciprocating rotation of the outer shell 301, the clamping arm 208 can clean the outer wall of the outer shell 301, further improving the image acquisition and detection of the detection component 3 for the nuclear accident site.

[0054] Specifically, the servo motor 410 drives the assembly cylinder 409 to rotate, thereby driving the axial flow fan blade 407 to rotate. Then, air is introduced through the air inlet hole 412, and the gas is discharged through the air blowing hole 411, so as to be able to blow and wash the outer wall of the outer shell 301, preventing dust and debris from contaminating the outer wall of the outer shell 301. With the cooperation of the rotating seat 201, the first telescopic arm 202, and the second telescopic arm 203, the mechanical claw 204 is displaced to the outer shell 301, so that the clamping arm 208 fits against the outer wall of the outer shell 301. At the same time, the outer shell 301 is displaced into the assembly cavity 303. Thus, the limit block 402 slides downward in the limit groove 416, driving the driven rod 404 rotating between the two limit blocks 402 to move downward. The gear 405 arranged on the driven rod 404 can mesh with the face gear 413 arranged on the outer wall of the top of the assembly cylinder 409, so as to be able to drive the driven rod 404 to rotate. Through the threaded clamping design of the reciprocating screw groove and the screw block 406 arranged on the driven rod 404, the screw block 406 is driven to reciprocate on the driven rod 404, thereby driving the telescopic rod 408 to displace. Through the third return spring 415 arranged inside the telescopic rod 408, the end of the telescopic rod 408 always abuts against the inner wall of the assembly cylinder 409, so that the end of the telescopic rod 408 reciprocates in an arc. Through the vertical rod 414 fixedly installed between the telescopic rod 408 and the bottom of the outer shell 301, the outer shell 301 can reciprocally rotate, thereby increasing the detection range of the detection component 3. At the same time, under the rotation of the outer shell 301, the rubber strip arranged on the outer wall of the clamping arm 208 can clean the outer wall of the outer shell 301. With the cooperation of the axial flow fan blade 407, it can effectively prevent dust and debris from contaminating the outer wall of the outer shell 301, improving the image acquisition and detection effect of the detection component 3.

Specifically, as Figure 1 and Figures 3 - 6 shown, a water droplet convex 214 is arranged at the end of the fixed rod 212. A convex block 223 is slidably installed inside the clamping arm 208. The outer wall of the convex block 223 is in contact with the outer wall of the water droplet convex 214. A first return spring 225 is fixedly installed between the bottom of the convex block 223 and the inner wall of the clamping arm 208. A first connecting rod 224 is fixedly installed at the bottom of the convex block 223. The end of the first connecting rod 224 is hingedly installed with a second connecting rod 226. The end of the second connecting rod 226 is hingedly connected to the outer wall of the gripping plate 209;

[0056] A rigid plate 210 is arranged at the bottom of the moving disk 211. A plurality of bases 222 are arrayedly installed on the outer wall of the rigid plate 210. A sliding rod 221 is rotatably installed on each of the plurality of bases 222. The ends of the sliding rods 221 all slide inside the moving disk 211 and the fixed rod 212;

[0057] A collar 215 is slidably mounted on the output end of the electric cylinder 219. A plurality of connecting rods 216 are arrayedly mounted at the bottom of the collar 215 and penetrate through the moving disk 211. The bottom ends of the plurality of connecting rods 216 are fixedly mounted with a clamping disk 217 which can form a clamping connection with the sliding end of the sliding rod 221. The downward movement of the clamping disk 217 can release the clamping connection with the sliding end of the sliding rod 221. A tension spring 218 is fixedly mounted between the outer wall of the clamping disk 217 and the moving disk 211. A conical plate 220 is fixedly mounted at the bottom of the rigid plate 210;

[0058] Tooth grooves 227 are arrayedly formed at the bottom of the gripping plate 209. Ball bearings 213 are rotatably mounted at the ends of the tooth grooves 227. Card slots are arrayedly formed on the circumferential outer wall of the conical plate 220, and the card slots can form a clamping connection with the tooth grooves 227.

[0059] The telescopic movement of the electric cylinder 219 can drive the moving plate 211 to move away from and close to the assembly roller 205. Through the cooperation of the assembly plate 206, the chute 207, the slider 501 and the fixed rod 212, multiple clamping arms 208 can be moved closer to and away from each other, so as to clamp and process the nuclear radioactive items at the nuclear accident site. By setting the first return spring 225, the water droplet protrusion 214 provided at the end of the fixed rod 212 and the protrusion 223 slidably installed inside the clamping arm 208 are always in contact. When the clamping arm 208 rotates for clamping, the water droplet protrusion 214 can drive the protrusion 223 to displace downward, so that the first connecting rod 224 displaces downward. By setting the second connecting rod 226 hinged at the end of the first connecting rod 224, the gripping plate 209 hinged to it can be driven to rotate, so that the gripping plate 209 can receive the nuclear radioactive item, preventing the nuclear radioactive item from falling and causing the diffusion of nuclear radiation substances. When crushing treatment is required at the nuclear accident site, by controlling the electric cylinder 219, the moving plate 211 is moved closer to the assembly roller 205, so that multiple clamping arms 208 are relatively opened. When the moving plate 211 is displaced towards the assembly roller 205 by a certain distance, the bottom of the assembly roller 205 will abut against the collar 215 and drive it to move downward. The clamping disk 217 is moved downward through multiple connecting rods 216, so that the clamping between the end of the sliding rod 221 and the clamping disk 217 is released. The sliding rod 221 slides under the gravity of the rigid plate 210, so that the rigid plate 210 moves downward. Then, by controlling the electric cylinder 219 to move the moving plate 211 away from the assembly roller 205, the clamping arm 208 rotates to clamp the rigid plate 210. The outer wall of the gripping plate 209 fits with the outer wall of the rigid plate 210. At the same time, the teeth 227 provided at the bottom of the gripping plate 209 can form a clamping connection with the card slots opened on the outer wall of the conical plate 220, so that the mechanical claw 204 is kept stable. The conical plate 220 provided at the bottom of the rigid plate 210 can crush the items at the nuclear accident site. When the body 1 tilts during the traveling process, a fulcrum can be formed through the mechanical claw 204 controlled by the rotating seat 201, the first telescopic arm 202 and the second telescopic arm 203. The ends of the teeth 227 provided at the bottom of the gripping plate 209 are all rotatably installed with balls 213, which can prevent the body from tipping over when the body 1 tilts, and at the same time improve the traveling ability of the body 1 at the nuclear accident site.

[0060] Example 3 further optimizes a nuclear radiation detection robot provided in Example 2. Specifically, as Figure 2 、 Figure 7 and Figure 8As shown in the figure, a protection component 5 is arranged between the inside of the slider 501 and the chute 207. The protection component 5 includes that cylinders 502 are fixedly installed on the inner walls of the chute 207. A round rod 507 is fixedly installed at the end of the cylinder 502. A fixed cone block 505 is fixedly installed at the end of the round rod 507. A movable cone block 506 is slidably installed on the outer wall of the round rod 507. Slideways 508 are symmetrically formed through the outer wall of the slider 501 and are all located in the chute 207. Two wedge-shaped blocks 503 are symmetrically and slidably installed inside the slider 501 and are located in the slideways 508. Second return springs 504 are fixedly installed between the two wedge-shaped blocks 503 and the inside of the slider 501. The wedge-shaped block 503 can form a clamping connection with the fixed cone block 505;

[0061] A storage box 101 is arranged on the top outer wall of the machine body 1, and an electric cover plate 102 is arranged on the top of the storage box 101.

[0062] In order to solve the problem that the nuclear radiation substances at the nuclear accident site cause damage to the electric cylinder 219. When the mechanical claw 204 is in the clamping state, if the electric cylinder 219 is damaged and resets by itself, it will cause the nuclear radiation items to fall and the nuclear radiation substances to spread. By setting the protection component 5, the wedge-shaped block 503 is arranged inside the slider 501. Under the action of the second return spring 504, the wedge-shaped block 503 is always located in the slideway 508. When the slider 501 displaces a certain distance, the fixed cone block 505 enters the slideway 508, and the fixed cone block 505 can form a clamping connection with the wedge-shaped block 503, which can prevent the slider 501 from resetting and causing the clamping arm 208 to open. When it is necessary to place the clamped item, the electric cylinder 219 can be used to continuously displace the slider 501. The wedge-shaped block 503 can pass through the movable cone block 506, and then the electric cylinder 219 can be used to reset the slider 501, so as to drive the movable cone block 506 to displace and fit with the fixed cone block 505. Under the action of the conical surface of the movable cone block 506, the wedge-shaped block 503 can be displaced, so as to release the clamping connection between the wedge-shaped block 503 and the fixed cone block 505, so that the mechanical claw 204 can place the clamped item, improving the reliability of the mechanical claw 204. By setting the storage box 101, the nuclear radiation items at the nuclear accident site can be collected and transported, so that they can be centrally processed.

[0063] The use process of the nuclear radiation detection robot provided by the present invention is as follows:

[0064] The servo motor 410 drives the assembly cylinder 409 to rotate, thereby causing the axial flow fan blade 407 to rotate. Through the air blowing holes 411, the outer wall of the outer shell 301 can be continuously cleaned. Under the action of the rotating seat 201, the first telescopic arm 202, and the second telescopic arm 203, the mechanical claw 204 can be driven to displace onto the outer shell 301, thereby protecting the outer shell 301 and preventing items generated by the explosion at the nuclear accident site from hitting the outer shell 301 and causing damage to the internal devices. At the same time, the outer wall of the clamping arm 208 is attached to the outer wall of the outer shell 301, and the outer shell 301 is moved downward, so that the gear 405 provided on the outer wall of the driven rod 404 meshes with the face gear 413 provided at the top of the assembly cylinder 409, thereby driving the driven rod 404 to rotate. The reciprocating screw groove provided on the driven rod 404 drives the screw block 406 to reciprocate. Under the action of the telescopic rod 408, the third return spring 415, the vertical rod 414, and the inner wall of the assembly cylinder 409, the outer shell 301 reciprocates, thereby increasing the detection range of the detection component 3. At the same time, the rotation of the outer shell 301 enables the rubber strip provided on the clamping arm 208 to clean the outer wall of the outer shell 301. In cooperation with the axial flow fan blade 407, it can effectively prevent dust and debris at the nuclear accident site from contaminating the outer shell 301 and the visual lens 302. By providing the rigid plate 210, the moving disk 211 can be displaced by the electric cylinder 219, so that the assembly roller 205 abuts against the collar 215 and displaces it, thereby displacing the clamping disk 217 and releasing the clamping between the clamping disk 217 and the end of the sliding rod 221. Under the action of gravity, the rigid plate 210 can move downward. Then, the clamping arm 208 clamps the rigid plate 210 through the electric cylinder 219, thereby fixing the mechanical claw 204. The conical plate 220 fixedly installed at the bottom of the rigid plate 210 can crush the items at the nuclear accident site. The reset of the rigid plate 210 can be achieved by controlling the mechanical claw 204 to displace to the top of the outer shell 301 and move downward. Through the outer shell 301, the rigid plate 210 is reset and the end of the sliding rod 221 forms a clamping connection with the clamping disk 217. By providing the protection component 5, the wedge block 503 provided inside the slider 501 can form a clamping connection with the fixed cone block 505, thereby preventing the clamping arm 208 from resetting during the clamping process in the case of damage to the electric cylinder 219 or delay or loss of control signals in a high-radiation environment, resulting in the nuclear radiation items falling off and causing the risk of nuclear radioactive material diffusion. Through the continuous displacement of the slider 501, the wedge block 503 can pass through the movable cone block 506 through the inclined plane. Through the reset displacement of the slider 501, the movable cone block 506 is driven to fit with the fixed cone block 505. Under the action of the conical surface of the movable cone block 506, the clamping connection between the wedge block 503 and the fixed cone block 505 is released, thereby enabling the clamped items to be placed.
