Description

Technical Field

[0001] This utility model relates to the field of nuclear contamination detector technology, specifically a nuclear contamination detector. Background Technology

[0002] In the field of nuclear contamination detection, portable nuclear radiation detection equipment often employs an external detection probe design to adapt to complex scenarios such as narrow gaps (e.g., gaps between equipment cabinets), floor corners, and high-altitude targets. However, existing equipment has significant shortcomings: Firstly, the detection probe lacks a stable fixing structure. When it needs to be attached to a metal surface (e.g., nuclear facility pipelines, equipment casings) for point detection, it must be manually held to maintain its position, which is prone to data deviation due to hand shaking, and prolonged handholding increases the operational burden. Secondly, although some equipment attempts to add adsorption components, there is no synchronous retraction and extension or power-off protection mechanism. The adsorption components are exposed and susceptible to impact damage, and continuous power supply shortens the component's lifespan. In addition, the transmission and functional components of existing equipment mostly operate independently, making the operation steps cumbersome and difficult to quickly switch detection modes, failing to meet the needs of efficient and accurate nuclear contamination detection. Therefore, there is an urgent need for a nuclear contamination detector that can solve the above problems. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4The present invention provides a nuclear contamination detector, comprising: a portable nuclear radiation detector body 1, a square tube 2 installed on the top of the portable nuclear radiation detector body 1, a mounting box 4 installed on the top of the square tube 2, and a detection probe 5 installed on the top of the mounting box 4. It also includes: a sliding opening 6 on one side of the outer wall of the square tube 2; a motion component 7 rotatably mounted on the inner wall of the square tube 2; a containment component 8 installed on one side of the outer wall of the motion component 7; a power connection component 9 installed on the other side of the outer wall of the motion component 7; an electromagnet 10 slidably connected to the inner wall of the mounting box 4; a spring rod 11 installed on one side of the inner wall of the mounting box 4, with one end of the spring rod 11 connected to the electromagnet 10; a wire 12 connected to one side of the outer wall of the electromagnet 10, with one bottom end of the wire 12 connected to a connector 13 fixed on the inner wall of the square tube 2; and a worm gear 3 rotatably mounted on one side of the outer wall of the square tube 2.

[0015] It should be noted here that: the portable nuclear radiation detector body 1 is the basic support. Due to its portability and real-time monitoring capability, the portable nuclear radiation detector body 1 is widely used in fields such as nuclear safety supervision, industrial production and environmental monitoring. As prior art in this application, its working principle and operation method will not be described in detail again. The square tube 2 on the top of the portable nuclear radiation detector body 1 is used to install components such as the motion component 7. The mounting box 4 on the top of the square tube 2 carries the electromagnet 10 and the spring rod 11. The detection probe 5 on the top of the mounting box 4 is external and can directly contact narrow gaps (such as equipment cabinet gaps), ground corners or high targets, which facilitates flexible detection. When it is necessary to attach the detection probe 5 to a metal surface (such as nuclear facility pipelines, equipment shells) for fixed-point detection, rotate the worm gear 3 on one side of the outer wall of the square tube 2, and the worm gear 3 drives the motion component 7 on the inner wall of the square tube 2 to rotate. When the motion component 7 rotates, it synchronously drives the enclosure component 8 on one side to descend along the sliding opening 6 of the square tube 2, and the power connection component 9 on the other side to rise. After the enclosure assembly 8 is lowered, it releases the obstruction to the electromagnet 10 inside the mounting box 4. At this time, the elastic rod 11 on one side of the inner wall of the mounting box 4 releases its elastic force, pushing the electromagnet 10 to move out of the mounting box 4 a part, so that one side of the electromagnet 10 can contact the metal surface. At the same time, the power connection component 9 rises to contact the connector 13 fixed to the inner wall of the square tube 2. The power connection component 9 supplies power to the electromagnet 10 through the wire 12. After being energized, the electromagnet 10 is attracted to the metal surface, so that the position of the detection probe 5 is stable and meets the requirements of fixed-point detection. After the test is completed, the worm gear 3 is rotated in the reverse direction, which drives the motion component 7 to rotate in the reverse direction. This causes the enclosure component 8 to rise and block the electromagnet 10 again. The power connection component 9 descends and separates from the connector 13, de-energizing the electromagnet 10. Subsequently, it is pushed back into the mounting box 4 by the enclosure component 8, thus protecting the electromagnet 10.

[0016] In a preferred embodiment, the motion component 7 includes two gears 701, a toothed belt 702 connected to the two gears 701, and a worm gear 703 mounted on one end of the gears 701.

[0017] It should be noted here that when the worm 3 is rotated, the worm 3 meshes with the worm wheel 703 at one end of the gear 701, driving the worm wheel 703 and the gear 701 connected to it to rotate. After one gear 701 rotates, it drives another gear 701 to rotate synchronously through the toothed belt 702 connected by the transmission, so that the entire motion assembly 7 forms a stable transmission. During rotation, the toothed belt 702 drives the enclosure assembly 8 and the power connection assembly 9 connected to it to move up and down, providing a power transmission basis for the subsequent extension and power supply of the electromagnet 10.

[0018] In a preferred embodiment, a limit frame 14 is installed on the inner wall of the square tube 2, and the toothed belt 702 forms a sliding fit with the limit frame 14.

[0019] It should be noted here that when the toothed belt 702 of the motion component 7 drives the enclosure component 8 and the power connection component 9 to rise and fall, the limiting frame 14 on the inner wall of the square tube 2 restricts the movement trajectory of the toothed belt 702. The limit frame 14, through its sliding engagement with the toothed belt 702, prevents the toothed belt 702 from shifting, shaking, or disengaging from the gear 701 during transmission, ensuring that the toothed belt 702 always runs along a fixed path, thereby guaranteeing the stability and accuracy of the lifting and lowering actions of the enclosure assembly 8 and the power connection assembly 9.

[0020] In a preferred embodiment, the enclosure assembly 8 includes a first connecting block 801, a slider 802 mounted on one end of the first connecting block 801, and a baffle 803 mounted on the outer wall of one side of the slider 802.

[0021] It should be noted here that when the toothed belt 702 of the motion component 7 rotates, it drives the entire enclosure component 8 to move through the first connecting block 801; The slider 802 cooperates with the sliding opening 6 of the square tube 2 to play a guiding role during the lifting and lowering of the enclosure component 8, ensuring that the baffle 803 moves stably along the sliding opening 6; In the initial state, the baffle 803 is located below the mounting box 4, preventing the electromagnet 10 from extending. When the toothed belt 702 drives the enclosure assembly 8 to descend, the baffle 803 moves down along the sliding opening 6 with the slider 802, releasing the obstruction of the electromagnet 10. After the test is completed, the enclosure assembly 8 rises, and the baffle 803 moves up to push the electromagnet 10 back into the mounting box 4, while simultaneously re-forming the obstruction, thus achieving the limitation and protection of the electromagnet 10.

[0022] In a preferred embodiment, the power connection component 9 includes a second connecting block 901, a power connector 902 installed at one end of the second connecting block 901, and a power connection wire 903 connected to the bottom of the power connector 902, and the power connection wire 903 is connected to the portable nuclear radiation detector body 1.

[0023] It should be noted here that when the toothed belt 702 of the motion component 7 rotates, it drives the entire power connection component 9 to rise through the second connecting block 901; When the power connection component 9 rises to the designated position, the power connection head 902 contacts the connector 13 fixed to the inner wall of the square tube 2, forming a circuit connection; The portable nuclear radiation detector body 1 transmits electrical energy to the connector 902 via the connecting wire 903, and then to the electromagnet 10 via the connector 13 and the wire 12, so as to power the electromagnet 10 and make it magnetic. After the detection is completed, the connecting component 9 descends, the connector 902 separates from the connector 13, the circuit is broken, and the electromagnet 10 is de-energized and loses its magnetism.

[0024] In a preferred embodiment, the elastic rod 11 includes a fixed tube 1101, a movable rod 1102 slidably connected to the inner wall of the fixed tube 1101, and a spring 1103 disposed on the inner wall of the fixed tube 1101.

[0025] It should be noted here that: in the initial state, the baffle 803 of the enclosure assembly 8 blocks the electromagnet 10. At this time, the electromagnet 10 squeezes the movable rod 1102 of the elastic rod 11, and the movable rod 1102 slides towards the inner wall of the fixed tube 1101, compressing the spring 1103 inside the fixed tube 1101. The spring 1103 stores elastic potential energy. When the enclosure assembly 8 descends and releases the obstruction to the electromagnet 10, the spring 1103 releases its elastic potential energy, pushing the movable rod 1102 to extend out of the fixed tube 1101, thereby driving the electromagnet 10 to move out of the mounting box 4, ensuring that the electromagnet 10 can smoothly contact the metal surface. After the inspection is completed, the enclosure assembly 8 rises and pushes the electromagnet 10. The electromagnet 10 squeezes the movable rod 1102, causing the spring 1103 to be compressed again. The movable rod 1102 retracts into the fixed tube 1101, preparing for the next extension of the electromagnet 10.

[0026] Working principle: The device is based on the portable nuclear radiation detector body 1. The square tube 2 installed on the top provides installation and movement space for components such as the motion component 7 and the enclosure component 8. The mounting box 4 on the top of the square tube 2 is used to support the electromagnet 10 and the elastic rod 11. The detection probe 5 on the top of the mounting box 4 adopts an external design, which can be directly inserted into narrow gaps (such as equipment cabinet gaps), ground corners or high target areas to achieve flexible detection.

[0027] When the detection probe 5 needs to be attached to a metal surface such as a nuclear facility pipeline or equipment shell for fixed-point detection, the worm 3 on one side of the outer wall of the square tube 2 is rotated. The worm 3 meshes with the worm wheel 703 at one end of the gear 701 in the motion component 7, driving the worm wheel 703 and the connected gear 701 to rotate.

[0028] After one gear 701 rotates, it drives another gear 701 to rotate synchronously through the toothed belt 702 connected by the transmission (the limiting frame 14 on the inner wall of the square tube 2 slides with the toothed belt 702 to prevent the toothed belt 702 from deviating). The toothed belt 702 simultaneously drives the components connected on both sides to move: on one side, the slider 802 of the enclosure component 8 is driven to descend along the sliding opening 6 through the first connecting block 801, so that the baffle 803 moves down; on the other side, the power receiving head 902 of the power receiving component 9 is driven to rise through the second connecting block 901.

[0029] After the baffle 803 of the enclosure assembly 8 descends, it releases the obstruction to the electromagnet 10 inside the mounting box 4. At this time, the spring 1103 in the fixed tube 1101 of the elastic rod 11 on one side of the inner wall of the mounting box 4 releases elastic potential energy, pushes the movable rod 1102 to extend, and then drives the electromagnet 10 to move out part of the mounting box 4, so that one side of the electromagnet 10 contacts the metal surface.

[0030] At the same time, the power connector 902 of the power connection component 9 rises to contact the connector 13 fixed to the inner wall of the square tube 2. The portable nuclear radiation detector body 1 transmits electrical energy to the power connector 902 through the power connection wire 903, and then transmits it to the electromagnet 10 through the connector 13 and the wire 12 to power the electromagnet 10, so that it generates magnetism and is attracted to the metal surface, ensuring the stable position of the detection probe 5 and realizing fixed-point detection.

[0031] After the test is completed, the worm gear 3 is rotated in the reverse direction, causing the motion component 7 to rotate in the reverse direction: the enclosure component 8 rises, the baffle 803 moves upward to block the electromagnet 10 again; the power connection component 9 descends, the power connection head 902 separates from the connector 13, and the electromagnet 10 is de-energized and loses its magnetism. Then the baffle 803 pushes the electromagnet 10 to squeeze the movable rod 1102 of the elastic rod 11, causing the spring 1103 to compress, the movable rod 1102 to retract into the fixed tube 1101, and the electromagnet 10 is retracted into the mounting box 4, thus achieving protection.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

No reference numerals in the claims should be construed as limiting the scope of the claims.
