Description

Technical Field

[0001] This utility model relates to the field of detection instrument technology, specifically to a hand and foot surface contamination detector. Background Technology

[0002] The hand and foot alpha and beta surface contamination monitor (hereinafter referred to as the monitoring system) is mainly used for safety monitoring of personnel in radioactive areas such as nuclear medicine departments, radiopharmaceutical plants, and irradiation centers. It focuses on detecting radioactive contamination on the surfaces of key areas such as the hands and feet. Currently, ordinary foot detectors on the market lack protection above the standing area, which can lead to dust and other heavy objects falling onto the detector surface. This can affect measurement accuracy and damage the detector's measuring film, potentially causing the monitoring system to malfunction. Alternatively, a simple shield is used for protection, which needs to be removed manually, posing a risk of cross-contamination due to hand contact and affecting personnel safety.

[0003] In view of this, this application proposes a hand and foot surface contamination detector, which uses facial recognition to intelligently control the opening and closing of the protective cover, thereby preventing dust and other heavy objects from falling onto the detector surface and damaging the detector's measuring film, and also solving the problem of cross-contamination caused by the need to manually remove the cover.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0030] like Figure 1-5As shown, this embodiment provides a hand and foot surface contamination detector, which includes a mounting body 100, which is generally L-shaped. A foot detector 200 is mounted and fixed at the bottom of the mounting body 100, and a hand detector 300 is also mounted and fixed on the mounting body 100 via a connector 310. The mounting height of the hand detector 300 on the mounting body 100 is higher than that of the foot detector 200. Furthermore, a foot protective cover 210 is provided on the foot detector 200. The foot protective cover 210 can rotate relative to the foot detector 200, thereby automatically covering the foot detector 200 when not in use. Furthermore, a detection module 110 is also provided on the main installation body 100. The detection module 110 can be a face recognition module. When the face recognition module recognizes the person to be tested, it can cause the foot protection cover 210 to open automatically, thereby meeting the needs of the person to be tested. When the face recognition module does not recognize the person to be tested, it can cause the foot protection cover 210 to close automatically, thereby protecting the foot detector 200.

[0031] Understandably, this application, through the intelligent identification of the person to be tested by the detection module 110, can better facilitate the automatic opening and closing of the foot protection cover 210. On the one hand, it can better prevent dust and other heavy objects from falling onto the surface of the foot detector 200 and avoid damaging the measuring film on the foot detector 200. On the other hand, it can better avoid cross-contamination caused by the need for manual operation of the foot protection cover 210.

[0032] In some embodiments, a rotating shaft is provided on the bottom of the mounting body 100, and a drive motor 120 is provided on one side of the rotating shaft. A drive gear 121 is sleeved on the output shaft of the drive motor 120, and a driven gear 410 is sleeved on the rotating shaft. In the assembled state, the output shaft of the drive motor 120 is connected to the rotating shaft through the meshing of the drive gear 121 and the driven gear 410. Furthermore, the foot cover 210 is connected and mounted on the rotating shaft. By driving the rotating shaft to rotate through the drive motor 120, the rotation of the foot cover 210 can be better realized, thereby realizing the automatic opening and closing of the foot cover 210 on the foot detector 200.

[0033] Furthermore, when the person to be tested approaches the mounting body 100 and the detection module 110 on the mounting body 100 recognizes the person, the drive motor 120 operates further, causing the rotating shaft to rotate under the drive of the drive motor 120, thereby automatically opening the foot protection cover 210, allowing the person to stand on the foot detector 200 for detection; when the person to be tested leaves the mounting body 100 and the detection module 110 on the mounting body 100 fails to recognize the person, the drive motor 120 operates further, causing the rotating shaft to rotate in the opposite direction under the drive of the drive motor 120, thereby automatically closing the foot protection cover 210, achieving the purpose of protecting the foot detector 200.

[0034] In some embodiments, multiple seated bearings 130 are fixedly mounted on the bottom of the mounting body 100 by bolts. The multiple seated bearings 130 are all sleeved on the rotating shaft, thereby achieving better positioning and installation of the rotating shaft on the mounting body 100, and enabling the rotating shaft to rotate axially relative to the mounting body 100 under the drive of the drive motor 120. When the foot protection cover 210 is connected to the rotating shaft, the rotating shaft can better drive the foot protection cover 210 to rotate, thereby realizing the opening and closing of the foot protection cover 210.

[0035] In some embodiments, the foot cover 210 has a strip-shaped hole 211 on one or both sides along the axial direction of the rotating shaft. The foot cover 210 is sleeved on the rotating shaft through the strip-shaped hole 211, and the cross-sectional shape of the position on the rotating shaft corresponding to the strip-shaped hole 211 is also elongated, so that it matches the shape of the strip-shaped hole 211.

[0036] It is understandable that, since the cross-sectional shape of the corresponding position on the rotating shaft is elongated, when the foot cover 210 is fitted onto the strip hole 211, the rotating shaft can cooperate with the strip hole 211 to form a limit, so that the foot cover 210 cannot rotate around the circumferential direction of the rotating shaft. Therefore, when the rotating shaft rotates, it can drive the foot cover 210 to rotate synchronously, and thus the rotating shaft can drive the foot cover 210 to open and close.

[0037] In some embodiments, the rotating shaft includes a rod portion 401 in the middle position and a limiting end 402 at the end of the rod portion 401. The radial dimension of the limiting end 402 is larger than the radial dimension of the rod portion 401. Therefore, when the foot cover 210 is sleeved on the rod portion 401, the limiting end 402 can limit the foot cover 210 to prevent it from falling off the rod portion 401, thereby improving safety.

[0038] Furthermore, a connecting block 403 is provided on one side of the limiting end 402 in the axial direction. The rod 401 and the limiting end 402 are separate structures, and the limiting end 402 is detachably connected to the rod 401 through the connecting block 403. When assembling the rod 401, the connecting block 403 of the limiting end 402 is first passed through the strip hole 211 on the foot protection cover 210, and then the rod 401 is connected to the connecting block 403. Thus, while the rod 401 and the limiting end 402 are assembled to form a rotating shaft, the foot protection cover 210 is sleeved and installed on the rotating shaft.

[0039] As can be understood from the above, the foot protector 210 is specifically fitted onto the connecting block 403 through the strip-shaped hole 211. That is, the cross-sectional shape of the connecting block 403 is elongated to match the shape of the strip-shaped hole 211, so that the connecting block 403 can limit the foot protector 210, thereby achieving the effect that the rotating shaft can synchronously drive the foot protector 210 to rotate. Furthermore, separating the rotating shaft into a rod portion 401 and a limiting end 402 also facilitates the installation and limiting of the foot protector 210 on the rotating shaft.

[0040] In some embodiments, a sleeve hole 404 is provided on the side of the connecting block 403 away from the limiting end 402, the sleeve hole 404 allowing the end of the rod portion 401 to extend into it; a first through hole 405 is provided through the connecting block 403 on its circumferential sidewall, and the first through hole 405 communicates with the sleeve hole 404. A second through hole 406 is provided through the rod portion 401 on its circumferential sidewall, and when the end of the rod portion 401 extends into the sleeve hole 404, the second through hole 406 is also located in the sleeve hole 404. Furthermore, after rotating the rod 401 to a certain extent, the first through hole 405 and the second through hole 406 can be aligned. Then, a fixing bolt 407 can be inserted into the corresponding first through hole 405 and second through hole 406 to better achieve a fixed connection between the connecting block 403 and the rod 401, thereby achieving a fixed connection between the rod 401 and the limiting end 402, forming a rotating shaft with a stable structure. When the drive motor 120 drives the rod 401 to rotate through the driving gear 121 and the driven gear 410, the rod 401 can synchronously drive the connecting block 403 and the limiting end 402 to rotate. The rotation of the connecting block 403 can also synchronously drive the rotation of the foot protection cover 210, thereby better achieving the automatic opening or closing of the foot protection cover 210.

[0041] In some embodiments, a limiting block 420 is fixedly installed on the rotating shaft. The limiting block 420 has a protrusion 421 in the circumferential direction, which extends radially along the rotating shaft. A stop screw 140 is fixedly installed on the bottom of the mounting body 100, and the position of the stop screw 140 corresponds to the position of the limiting block 420. Furthermore, during the rotation of the rotating shaft, the rotating shaft will drive the limiting block 420 to rotate synchronously, so that the protrusion 421 on the limiting block 420 also rotates. One end of the stop screw 140 is fixed to the mounting body 100, and the other end is in the path of the protrusion 421's rotation. When the protrusion 421 rotates and abuts against the stop screw 140, the stop screw 140 can limit the circumferential rotation of the rotating shaft, thereby preventing the rotating shaft from driving the foot protection cover 210 to rotate further.

[0042] It is understandable that by setting the limit block 420 and the stop screw 140, the maximum opening degree of the foot protection cover 210 can be adjusted by adjusting the position of the limit block 420 on the rotating shaft, so as to avoid the foot protection cover 210 opening too much under the drive of the drive motor 120, thus playing a certain mechanical limiting effect.

[0043] In some embodiments, an angle feedback plate is further provided on the rotating shaft, and a positioning sensor capable of detecting the angle feedback plate is provided on the bottom of the mounting body 100. Further, there are two angle feedback plates, designated as a first angle feedback plate 430 and a second angle feedback plate 440, and two positioning sensors, designated as a first positioning sensor 150 and a second positioning sensor 160. The first positioning sensor 150 is used to detect the first angle feedback plate 430, and the second positioning sensor 160 is used to detect the second angle feedback plate 440.

[0044] Understandably, during actual installation, both the first angle feedback plate and the second angle feedback plate 440 are fixedly mounted on the rotating shaft, and the first positioning sensor 150 and the second positioning sensor 160 are fixedly mounted on the mounting body 100. Furthermore, when the rotating shaft drives the foot protection cover 210 to a fully open state, the first angle feedback plate 430 is positioned in a position that can be detected by the first positioning sensor 150, and when the rotating shaft drives the foot protection cover 210 to a fully closed state, the second angle feedback plate 440 is positioned in a position that can be detected by the second positioning sensor 160.

[0045] As can be seen from the above, the first angle feedback plate 430 and the first positioning sensor 150 can monitor whether the foot protection cover 210 is fully open, and the second angle feedback plate 440 and the second positioning sensor 160 can monitor whether the foot protection cover 210 is fully closed. This can significantly improve the stability and safety of the foot protection cover 210 in use.

[0046] In some embodiments, since the foot detector 200 and drive motor 120 are both located at the bottom of the mounting body 100, and the drive motor 120 drives the rotating shaft through the drive gear 121 and the driven main wheel, in order to prevent the cables on the foot detector 200 from getting tangled and stuck on the drive gear 121, the driven gear 410 or the rotating shaft and other rotating parts, an isolation cover plate 170 is provided between the foot detector 200 and the drive motor 120 in this embodiment to isolate the foot detector 200 and improve the safety of the device.

[0047] Furthermore, the isolation cover 170 can also effectively reduce the impact of electromagnetic interference generated by the operation of the drive motor 120 on the foot detector 200, thereby improving the detection accuracy of the foot detector 200.

[0048] In some embodiments, the mounting body 100 is provided with a control unit 101, a breathing light 180, and a human-machine interaction display screen 190. The control unit 101 is electrically connected to the breathing light 180, the human-machine interaction display screen 190, the detection module 110, the drive motor 120, the first angle feedback plate 430, the second angle feedback plate 440, the first positioning sensor 150, the second positioning sensor 160, the hand detector 300, and the foot detector 200, thereby better realizing the automation of the hand and foot surface contamination detector of this embodiment.

[0049] In some embodiments, a caster 102 is provided at the bottom of the mounting body 100, which facilitates the movement of the mounting body 100.

[0050] The following describes in detail, with specific examples, a hand and foot surface contamination detector of this embodiment.

[0051] When testing is required, turn on the power button of the hand and foot surface contamination detector to power on the device. When the person to be tested approaches the device, the detection module 110 identifies the person and sends a signal to the control unit 101. The control unit 101 then controls the drive motor 120 to operate, which drives the foot protection cover 210 to open by rotating the shaft. As the first angle feedback plate 430 rotates with the shaft, when the first position sensor 150 detects the first angle feedback plate 430, the foot protection cover 210 is fully open. The first position sensor 150 sends a signal to the control unit 101, which then controls the drive motor 120 to stop working. The device then performs a self-test under the control of the control unit 101, and the breathing light 180 emits a yellow light. After the self-test is passed, the device's detection system enters the main detection phase. After the baseline update is completed, the breathing light 180 emits a green light, and the device enters the ready state. The human-machine interface display 190 will issue a voice prompt for the person being tested to stand on the foot detector 200, and then prompt the person to enter their identity information. After the identity information is entered, the human-machine interface display 190 will issue a voice prompt for the person to place their left hand and / or right hand into the hand detector 300 for testing. During this process, the breathing light 180 emits a flashing blue light. After the measurement is completed, if there is no contamination, the breathing light 180 will emit a green light and the result of no contamination will be displayed on the human-machine interface display 190. If contamination is detected, the breathing light 180 will emit a red light and the human-machine interface display 190 will issue an audible and visual alarm. At the same time, the human-machine interface display 190 will display the hand detector 300 or foot detector 200 that detected contamination. Furthermore, the person being tested can store the measurement result.

[0052] After the test is completed, the person to be tested leaves. For example, if the test module 110 does not recognize the person to be tested after 5 minutes, the test module 110 sends a signal to the control unit 101, which causes the control unit 101 to control the drive motor 120 to work, causing the rotating shaft to rotate in the opposite direction until the second positioning sensor 160 detects the second angle feedback plate 440, so that the foot protection cover 210 is in a completely closed state, and then the device can enter the next test cycle.

[0053] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
