The above-mentioned human nuclide radiation analyzer adopts a dual-detector mode to realize the monitoring of the radioactivity in the body of the examinee. It is in the shape of a cabinet. During detection, the person to be detected needs to stand inside the cabinet, making the analyzer large in volume and not convenient for transportation. Summary of the Invention

[0004] Aiming at the above-mentioned deficiencies existing in the prior art, the purpose of the utility model is to provide a human nuclide analyzer convenient for transportation, and solve the problem that the existing human nuclide radiation analyzer is large in volume and not convenient for transportation.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A human nuclide analyzer that is easy to transport includes a human pedal and an analyzer body arranged on one side of the human pedal, the analyzer body includes a test cabinet and a top seal, the top seal is detachably mounted on the top of the test cabinet and is arranged horizontally; a nuclear radiation detector for detecting human nuclides is installed in the cabinet of the test cabinet, the nuclear radiation detector is installed on a lifting mechanism, and can move up and down and position with the lifting mechanism. In this way, the analyzer is mainly composed of a human pedal, a test cabinet and a top seal, wherein the top seal is detachably connected to the test cabinet, the human pedal is located on one side of the test cabinet, and the three components can be transported separately and assembled after being transported to the site. During the test, the human pedal is moved to a position close to the cabinet of the test cabinet, and then the person to be tested stands on the human pedal, facing the test cabinet, and the nuclear radiation detector in the test cabinet is lifted and lowered by the lifting mechanism, and the human body in front of it is fully scanned and detected, and finally the data is sent to the background terminal. With the above structure, the human standing position and the test cabinet are separately arranged, which effectively reduces the volume of the analyzer and is more flexible and convenient to use.

[0007] Furthermore, the lower end of the test cabinet extends toward the human pedal and the upper end is open, including an inner frame and an outer cover assembled on the inner frame, the outer cover includes a base cover and a cabinet cover, a light-transmitting plate is embedded on the side of the cabinet cover facing the human pedal, and a cabinet door is rotatably installed on the opposite side of the light-transmitting plate. In this way, the lower end width of the test cabinet is large, has good stability, and is not easy to tip over under the action of external force. After the test cabinet is assembled from the inner frame and the outer cover, it has high strength and is lighter than the traditional cabinet, and is also easier to assemble. The light-transmitting plate provided can facilitate the emission of the detection light of the nuclear radiation detector, ensuring a better detection effect during detection. The cabinet door provided can be opened by maintenance personnel to facilitate maintenance and inspection of the internal lifting mechanism and nuclear radiation detector.

[0008] Furthermore, the inner frame is assembled from a plurality of vertical poles, reinforcement rods and leg rods. The vertical poles are distributed in a rectangular shape. The reinforcement rods are rectangular and fixedly mounted on the upper ends of the vertical poles. The leg rods are arranged horizontally and fixedly connected to the lower ends of the vertical poles, and one end extends in the direction of the human pedal. An anti-vibration foot is installed at the lower end of each leg rod. The outer covering includes a base covering and a front panel, a left side panel, a right side panel and a back panel installed on the base covering. In this way, the inner frame body has connecting rods in the horizontal and longitudinal directions, and the overall structure is stable. The leg rods extending outward can guide the human pedal. At the same time, the extending part can further increase the support surface of the lower end of the test cabinet, making the test cabinet more stable. The outer covering is connected by a plurality of plates, which can reduce the manufacturing cost and facilitate installation and disassembly.

[0009] Further, a mounting plate is detachably installed on the inner side of the top of the outer cover. A plurality of mounting lugs are provided at intervals on the lower end surface of the top seal corresponding to the mounting plate. After the mounting lugs penetrate through the mounting plate, they are connected to the inner side of the inner frame by fasteners. In this way, the top seal is fixed to the test cabinet through the mounting lugs. At the same time, the top seal is connected to the test cabinet through the mounting lugs, which is convenient for installation and the installation structure is stable.

Two legs are provided at intervals near the pedal supports at the lower end of the pedal main body. The pedal main body can move toward the test cabinet under the action of an external force, and the inner side is adjacent to the test cabinet. The pedal main body is placed above the leg rod of the test cabinet. In this way, the pedal main body is in a suspended state, and the leg rod can guide the moving direction of the human pedal. After the human pedal moves above the leg rod, it is closer to the nuclear radiation detector, meeting the set detection distance.

[0012] Further, one side of the top seal close to the human pedal extends out of the test cabinet and corresponds to the human pedal. A lighting lamp, an infrared detector and a camera are installed on the top seal. The lighting lamp, the infrared detector and the camera are all arranged on the side where the top seal extends out. The camera is a camera with a voice function. In this way, the camera can take pictures of the tested person so that the background personnel can observe the detection posture of the tested person and perform operations such as voice prompts only for the tested person. The lighting lamp can illuminate the surrounding environment, and the infrared detector can measure the height of the tested person by irradiating infrared light and send the height information to the background.

[0013] Further, the lifting mechanism includes a crossbar and two vertical slide rails fixedly installed on the crossbar. A slider matching with each vertical slide rail is provided on each vertical slide rail; a cross plate is installed between the two sliders, and the nuclear radiation detector is installed on the cross plate. One of the sliders can move up and down and be positioned under the drive of a transmission mechanism. In this way, the slider in the lifting mechanism realizes lifting through the transmission mechanism arranged on one side. The cross plate arranged between the two sliders can ensure that after one slider slides, the other slider moves synchronously together and drives the nuclear radiation detector to move.

[0021] As Figures 1-5 shown, the portable human nuclide analyzer provided in this embodiment includes a human pedal 1 and an analyzer main body provided on one side of the human pedal 1. The analyzer main body includes a test cabinet 2 and a top seal 6. The top seal 6 is detachably installed at the top of the test cabinet 2 and is horizontally arranged. A nuclear radiation detector 5 for detecting human nuclides is installed in the cabinet of the test cabinet 2. The nuclear radiation detector 5 is installed on a lifting mechanism 4 and can move up and down and be positioned along with the lifting mechanism 4. In this way, the analyzer mainly consists of a human pedal 1, a test cabinet 2, and a top seal 6. Among them, the top seal 6 is detachably connected to the test cabinet 2, and the human pedal 1 is located on one side of the test cabinet 2. The three components can be transported separately and assembled after being transported to the site. During the test, the human pedal 1 is moved to a position close to the cabinet of the test cabinet 2, and then the person to be tested stands on the human pedal 1 and faces the test cabinet 2. The nuclear radiation detector 5 in the test cabinet 2 is lifted and lowered by the lifting mechanism 4 to comprehensively scan and detect the human body in front of it, and finally the data is sent to the background terminal. With the above structure, the human standing position and the test cabinet 2 are separately arranged, effectively reducing the volume of the analyzer and making it more flexible and convenient to use.

[0022] Further, the lower end of the test cabinet 2 extends toward the human pedal 1, and the upper end is open, including an inner frame 21 and an outer cover 22 assembled on the inner frame 21, the outer cover 22 includes a base cover 221 and a cabinet cover, a light-transmitting plate 227 is embedded on the side of the cabinet cover facing the human pedal 1, and a cabinet door 226 is rotatably installed on the opposite side of the light-transmitting plate 227. In this way, the lower end width of the test cabinet 2 is large, has good stability, and is not easy to tip over under the action of external force. After the test cabinet 2 is assembled by the inner frame 21 and the outer cover 22, it has high strength, is lighter than the traditional cabinet, and is more convenient to assemble. The light-transmitting plate 227 provided can facilitate the emission of the detection light of the nuclear radiation detector 5, ensuring a better detection effect during detection. The cabinet door 226 provided can be opened by maintenance personnel to facilitate maintenance and inspection of the internal lifting mechanism 4 and the nuclear radiation detector 5.

[0023] Furthermore, the inner skeleton 21 is assembled from multiple vertical poles 211, reinforcement rods 212 and leg rods 213. The vertical poles 211 are distributed in a rectangular shape, the reinforcement rods 212 are rectangular and fixedly installed on the upper ends of the vertical poles 211, the leg rods 213 are horizontally arranged, fixedly connected to the lower ends of the vertical poles 211, and one end extends toward the direction of the human pedal 1, and an anti-vibration support foot 214 is installed at the lower end of each leg rod 213; the outer cover 22 includes a base cover 221 and a front panel 222, a left panel 223, a right panel 224 and a back panel 225 installed on the base cover 221. The left side panel 223 and the right side panel 224 are both composed of a connecting plate and arc-shaped plates installed on both sides of the connecting plate. The left and right sides of the connecting plate and the left and right sides of the arc-shaped plate are vertically bent to the same side and then horizontally bent to form connecting end plates. The connecting end plates of the connecting plate and the connecting end plates of the arc-shaped plate are tightly attached and connected and fixed by fasteners. The leg rod 213 extends out of the base cover 221. The leg rod 213 can be a telescopic rod in a specific application, or the leg rod 213 can be removed before transportation, and then assembled on site after the transportation is completed. In this way, the space occupied by the inner frame 21 is smaller during transportation. The cabinet door 226 is rotatably installed on one side of the left side panel 223 or the right side panel 224 (or arranged in the middle of the back panel 255), and the other end is provided with a magnetic lock for closing the cabinet door 226. In this way, the inner frame 21 has connecting rods in the horizontal and vertical directions, and the overall structure is stable. The outwardly extending leg rods 213 can guide the human pedal 1. At the same time, the extended part can further increase the support surface of the lower end of the test cabinet 2, making the test cabinet 2 more stable. The outer cover 22 is formed by connecting multiple plates, which can reduce the manufacturing cost and facilitate installation and disassembly.

[0024] Further, an installation plate 229 is detachably installed on the inner side of the top of the outer cover 22. Four installation lugs 61 distributed in a rectangle are provided at intervals on the lower end surface of the top seal 6 corresponding to the installation plate 229. After the installation lugs 61 penetrate through the installation plate 229, they are connected to the inner side of the inner skeleton 21 through fasteners.

At the same time, the top seal 6 is connected to the test cabinet 2 through the installation lugs 61, which is convenient for installation and the installation structure is stable.

[0025] Further, a handle is provided on each of the left and right sides of the analyzer main body. In this way, during the test, the tested person can stand with both hands holding the handles, which forms a support for the human body.

[0026] Further, the human pedal 1 includes a pedal main body 11. The front end and the outer edges of the left and right sides of the pedal main body 11 are bent downward to form pedal supports 12. Two legs 13 are provided at intervals at the lower end of the pedal main body 11, close to the pedal supports 12. The pedal main body 11 can move toward the test cabinet 2 under the action of an external force, and the inner side is adjacent to the test cabinet 2. The pedal main body 11 is placed above the leg rod 213 of the test cabinet 2. In this way, the pedal main body 11 is in a suspended state, and the leg rod 213 can guide the moving direction of the human pedal 1. After the human pedal 1 moves above the leg rod 213, it is closer to the nuclear radiation detector 5, meeting the set detection distance.

[0027] Further, one side of the top seal 6 close to the human pedal 1 extends out of the test cabinet 2 and corresponds to the human pedal 1. A lighting lamp 63, an infrared detector, and a camera 62 are installed on the top seal 6. The lighting lamp, the infrared detector, and the camera are all arranged on the side where the top seal 6 extends out. The camera 62 is a camera with a voice function. In this way, the camera can take pictures of the tested person so that the background personnel can observe the detection posture of the tested person and perform operations such as only voice prompts for the tested person. The lighting lamp can illuminate the surrounding environment, and the infrared detector can measure the height of the tested person by irradiating infrared light and send the height information to the background.

[0028] Further, the lifting mechanism 4 includes a cross arm 41 and two vertical slide rails 42 fixedly installed on the cross arm 41. A slider 43 that mates with each vertical slide rail is provided on each vertical slide rail; a cross plate 44 is installed between the two sliders 43, and the nuclear radiation detector 5 is installed on the cross plate 44. One of the sliders 43 can move up and down and be positioned under the drive of a transmission mechanism. Specifically, the cross arm 41 is clamped and fixed on a cross arm 41 support 3 inside the inner skeleton 21. The cross arm 41 support 3 includes four vertical rods 31 distributed in a rectangle. At the upper ends of the two vertical rods 31 on the same side, end supports 32 with upper slots 33 are fixed. A support plate 34 for supporting the cross arm 41 is fixed between the two end supports 32, and the two sides of the support plate 34 respectively correspond to the two slots 33 on the end supports 32. In this way, the slider 43 in the lifting mechanism 4 realizes lifting through a transmission mechanism arranged on one side. The cross plate 44 arranged between the two sliders 43 can ensure that after one slider 43 slides, the other slider 43 moves synchronously together and drives the nuclear radiation detector 5 to move.

[0029] Specifically, in practical applications, the lifting mechanism 4 can also adopt a screw and nut lifting mechanism 4, a rack and pinion lifting mechanism 4, or a worm and worm gear lifting mechanism 4.
