Description

Technical Field

[0001] The invention specifically relates to a robot directional shielding radiation device and a radiation monitoring method. Background Art

[0002] The irradiation environment is generally dominated by point sources, but most radiation is emitted from a point or a surface, so there is a clear radiation directionality.

[0003] The electronic components inside the robot are the most sensitive to radiation and also the part with the worst radiation resistance. At present, when shielding electronic components, all surfaces of the electronic components are generally shielded with a shielding body. The shielding body is usually a rectangular parallelepiped, with four sides plus the lower two sides, a total of six sides; because the shielding body material is generally lead material, the weight of the shielding body is very large, ranging from tens of kilograms to hundreds of kilograms, which makes the overall weight of the robot too large and the maneuverability is poor. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problem that the shielding body of the electronic components inside the existing robot is very heavy, resulting in the overall weight of the robot being too large and the maneuverability being poor, and to provide a robot directional shielding irradiation device and an irradiation monitoring method.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A robot directional shielding irradiation device is used for shielding electronic components inside the robot; the device is special in that it includes a turntable, a shielding body and a control module arranged inside the robot;

[0007] The turntable is arranged at the center of the robot body;

[0008] The shielding body is arranged on the turntable, a dose detector is arranged on one side surface thereof, and the other side surface is used to arrange the electronic components to be shielded; the shielding body is used to shield the electronic components to be shielded in the irradiation environment; the dose detector is used to monitor the radiation dose intensity around the robot in real time in the irradiation environment;

[0009] The dose detector and the turntable are respectively connected to the control module for communication. The control module is used to control the rotation of the turntable according to the radiation dose rate monitored by the dose detector, so that the shielding body is always located between the radiation source and the electronic components.

[0010] Furthermore, the rotation speed of the turntable is 5-10r / min.

[0011] Furthermore, the area of ​​the shielding body is 0.1-0.5 m2.

[0012] Furthermore, the material of the shielding body is lead plate.

[0013] Furthermore, the shielding body is a C-shaped structure; the dose detector is arranged on the convex surface of the shielding body facing the radiation source; and the electronic components are arranged on the concave surface of the shielding body.

[0014] At the same time, the present invention also provides a robot directional shielding radiation monitoring method, which is based on the above robot directional shielding radiation device and is special in that it includes the following steps:

[0015] Step 1: When the robot is in the irradiation environment, the turntable is controlled by the control module, and the radiation dose intensity is monitored in real time by the dose detector;

[0016] Step 2: determine in real time whether the radiation dose rate detected by the dose detector is greater than or equal to 0.2 mSv / h. If so, control the turntable to stop rotating; if not, return to step 1 so that the shielding body is always located between the radiation source and the electronic components, thereby realizing directional shielding of the electronic components from radiation.

[0017] Furthermore, in step 1, the rotation speed of the turntable is 5-10 r / min.

[0018] Furthermore, in step 1, the control module controls the turntable to rotate specifically as follows:

[0019] The control module controls the turntable to rotate clockwise in a horizontal plane.

[0020] Beneficial effects of the present invention:

[0021] 1. A robot directional shielding irradiation device of the present invention sets a dose detector on the inner surface of a shielding body, and uses the dose detector to monitor the radiation dose rate in the robot's environment in real time, thereby avoiding the electronic components inside the robot from being irradiated and increasing the service life of the electronic components.

[0022] 2. The robot directional shielding irradiation device of the present invention greatly enhances the maneuverability of the robot through the shielding body, turntable, dose detector and control module.

[0023] 3. The robot directional shielding irradiation device of the present invention reduces the shielding body of the electronic components in the existing robot to one surface and reduces the weight of the robot to 20% of the original weight.

[0024] 4. The present invention provides a robot directional shielding irradiation device, and the area of ​​the shielding body is 0.1-0.5㎡. If it is less than 0.1㎡, it is difficult to completely shield. Under the premise of meeting the shielding needs, the smaller the volume of the shielding body, the better. However, the electronic components of the circuit board for controlling the robot require a certain volume. According to the electronic components of the circuit board of the robot, the maximum area of ​​the shielding body is 0.5㎡.

[0025] 5. The present invention provides a robot directional shielding radiation monitoring method, which can realize real-time monitoring of radiation dose intensity through a dose detector, and utilizes a shielding body in conjunction with a turntable to enable the robot to shield radiation rays to the maximum extent within an acceptable range, thereby reducing the damage of radiation to electronic components, thereby improving the robot's radiation resistance and enabling it to work longer in a radiation environment.

[0026] 6. The present invention provides a robot directional shielding radiation monitoring method. The rotation speed of the turntable is 5-10r / min. If it is greater than 10r / min, the dose detector will not be able to detect the accurate radiation dose rate because it takes a certain amount of time to detect the radiation dose rate. If it is less than 5r / min, it rotates too slowly and affects the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] 1-shielding body, 2-dose detector, 3-electronic components. DETAILED DESCRIPTION

[0030] like Figure 1 As shown, a robot directional shielding irradiation device is used for shielding electronic components 3 inside the robot; it includes a turntable arranged inside the robot, a shielding body 1 and a control module; the turntable is arranged at the center inside the robot body; the shielding body 1 is arranged on the turntable, and a dose detector 2 is arranged on one side surface of the shielding body 1, and the other side surface is used to set the electronic components 3 to be shielded; the shielding body 1 is used to shield the electronic components 3 to be shielded in the irradiation environment; the dose detector 2 is used to monitor the radiation dose intensity around the robot in real time in the irradiation environment; the dose detector 2 and the turntable are respectively communicated with the control module, and the control module is used to control the rotation of the turntable according to the radiation dose rate monitored by the dose detector 2, so that the shielding body 1 is always located between the radiation source and the electronic components 3.

[0031] The robot directional shielding radiation-resistant reinforcement device of the present invention reduces the shielding body 1 of six faces to one, and sets the dose detector 2 and the electronic component 3 on the shielding body 1, and then sets the shielding body 1 on a turntable. The dose detector 2 measures the radiation dose intensity in real time, and uses the control module to control the turntable, so that the shielding body 1 is always kept between the radiation source and the electronic component 3, thereby ensuring the effective shielding protection of the electronic component 3 by the shielding body 1. Among them, the area of ​​the shielding body 1 is 0.1-0.5㎡. If it is less than 0.1㎡, it is difficult to completely shield; on the premise of meeting the shielding needs, the smaller the volume of the shielding body 1, the better; but the electronic components of the circuit board of the robot need a certain volume. According to the electronic components of the circuit board of the robot, it can be known that the maximum area of ​​the shielding body 1 is 0.5㎡. A shielding body 1 shields the radiation rays to the maximum extent within the range that the robot can bear, reduces the damage of the rays to the electronic components 3, thereby improving the radiation resistance of the robot, so that it can work longer in the radiation environment.

[0032] In this embodiment, the robot is a tracked robot, the rotation speed of the turntable is 10r / min, the area of ​​the shielding body 1 is 0.1㎡, and the material of the shielding body 1 is 5cm thick lead plate; the shielding body 1 is a C-shaped structure; the dose detector 2 is arranged on the convex surface of the shielding body 1 facing the radiation source; the electronic component 3 is arranged on the concave surface of the shielding body 1.

[0033] At the same time, the present invention also provides a robot directional shielding radiation monitoring method, based on the above robot directional shielding radiation device, including the following specific steps:

[0034] Step 1: When the robot is in an irradiation environment, the turntable is controlled to rotate by the control module, and the dose detector 2 is used to monitor the radiation dose intensity in real time;

[0035] Step 2: determine in real time whether the radiation dose rate detected by the dose detector 2 is greater than or equal to 0.2 mSv / h. If so, control the turntable to stop rotating; if not, return to step 1 so that the shielding body 1 is always located between the radiation source and the electronic component 3, thereby realizing directional shielding of the electronic component 3 from radiation.

[0036] Preferably, the rotation speed of the turntable is 5-10 r / min. If it is greater than 10 r / min, the dose detector 2 will not be able to detect the accurate radiation dose rate because it takes a certain amount of time to detect the radiation dose rate. If it is less than 5 r / min, the rotation is too slow and affects the work efficiency.
