Description

Technical Field

[0001] The utility model relates to the field of radioactive material detection equipment, in particular to a full-automatic low-background multi-channel gamma spectrometer. Background Art

[0002] Low background multi-channel gamma spectrometer is a radiation instrument that can measure the gamma ray energy of radioactive materials. Low background multi-channel gamma spectrometer is mainly used in quality and technical supervision and inspection departments at all levels, health and epidemic prevention, construction departments, environmental protection, geological exploration, building materials evaluation, scientific research, construction stations, quality inspection stations and processing units to conduct quantitative analysis of radioactive nuclides in various inorganic non-metallic materials such as various types of stone, ceramics, cement, sandstone, concrete and their products, radon measurement in air and soil, and can also be used in isotope production units for the determination of energy characteristic spectra of various radioactive nuclides.

[0003] The existing low-background multi-channel gamma spectrometer has a relatively fixed usage position and is not easy to move. This makes it very inconvenient to move the low-background multi-channel gamma spectrometer when it is moved to a new office or laboratory, which brings great inconvenience to the movers and is time-consuming and labor-intensive. At the same time, most spectrometers are placed directly on a base, and the spectrometer is pressed against the base by its own gravity. Therefore, the spectrometer is disturbed by external factors and moves relative to the base, which makes the spectrometer placed on the base less stable. Utility Model Content

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A fully automatic low-background multi-channel gamma spectrometer comprises a placement base, a spectrometer body and a support leg fixedly connected to the bottom of the placement base, wherein the spectrometer body is movably mounted on the top of the placement base, a support moving assembly is fixedly mounted below the inner side of the support leg, a moving wheel is fixedly mounted on the bottom of the support moving assembly, a lateral stabilization assembly is fixedly mounted on the top of the placement base, the lateral stabilization assembly is arranged outside the spectrometer body, and a limited position sliding frame is fixedly connected below the inner side of the support leg.

[0006] A further improvement of the technical solution of the utility model lies in that: the supporting moving assembly includes a supporting frame, a bidirectional threaded rod and two secondary threaded rods are rotatably installed inside the supporting frame, the two secondary threaded rods are perpendicular to the bidirectional threaded rod and are symmetrically arranged on the left and right, a transmission gear 1 is fixedly installed on the outside of the bidirectional threaded rod, the inner sides of the two secondary threaded rods are fixedly connected with a transmission gear 2 meshing with the transmission gear 1, the front and rear sides of the outside of the bidirectional threaded rod and the outsides of the two secondary threaded rods are threadedly connected with sliding blocks, the bottom of the sliding block is movably hinged to a support rod, the bottom of the support rod is movably hinged to a support platform, and the moving wheel is fixedly installed on the bottom of the support platform.

[0007] A further improvement of the technical solution of the utility model is that the lateral stabilization assembly includes a fixed block, the fixed block is fixedly connected to the top of the placement base, the internal thread of the fixed block is connected to a clamping screw, the outer side of the clamping screw is fixedly connected to a hand wheel, and the inner side of the clamping screw is movably installed with a stabilization block.

[0008] A further improvement of the technical solution of the utility model is that: a limiting block is arranged on the outer side of the support platform, and the limiting block is movably connected to the inside of the limiting sliding frame.

[0009] A further improvement of the technical solution of the utility model is that the sliding block is located outside the bidirectional threaded rod and the auxiliary threaded rod and is arranged in a cross shape.

[0010] A further improvement of the technical solution of the utility model is that: a handle penetrating the supporting leg and located outside the supporting leg is fixedly connected to the rear side of the bidirectional threaded rod.

[0011] A further improvement of the technical solution of the utility model is that: a total of four lateral stabilization components are provided, and the four lateral stabilization components are arranged in a left-right symmetrical manner based on the spectrometer body.

[0014] 1. The utility model provides a fully automatic low-background multi-channel gamma spectrometer, in which the spectrometer body is arranged on a placement base, and a support moving assembly is installed on the inner side of a support leg. Under normal circumstances, the support moving assembly is retracted to the inner side of the support leg so that the support leg contacts the ground to support the spectrometer body. When it is necessary to move, the support moving assembly is operated to slide down along the limit sliding frame so that the moving wheels contact the ground and gradually prop up the placement base, and the support legs leave the ground to cooperate with the moving wheels to facilitate the movement of the spectrometer body.

[0015] 2. The utility model provides a fully automatic low-background multi-channel gamma spectrometer. A lateral stabilization component is arranged on the outside of the spectrometer body on the placement base. The lateral stabilization component is operated to abut the spectrometer body from the side, so that the lateral stabilization component limits the spectrometer body, thereby preventing the spectrometer body from being disturbed by external factors and producing relative movement with the placement base, thereby improving stability.

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a fully automatic low-background multi-channel gamma spectrometer, including a placement base 1, a spectrometer body 3 and a support leg 2 fixedly connected to the bottom of the placement base 1, the spectrometer body 3 is movably installed on the top of the placement base 1, a support moving assembly 4 is fixedly installed at the lower inner side of the support leg 2, a moving wheel 5 is fixedly installed at the bottom of the support moving assembly 4, a lateral stabilization assembly 6 is fixedly installed on the top of the placement base 1, the lateral stabilization assembly 6 is arranged on the outer side of the spectrometer body 3, and a limited position sliding frame 7 is fixedly connected to the lower inner side of the support leg 2.

[0024] The spectrometer body 3 is set on the placement base 1, and a support and movement component 4 is installed on the inner side of the support leg 2. Under normal circumstances, the support and movement component 4 is retracted to the inner side of the support leg 2 so that the support leg 2 contacts the ground to support the spectrometer body 3. When it needs to be moved, the support and movement component 4 is operated to slide down along the limiting slide frame 7 so that the moving wheel 5 contacts the ground and gradually props up the placement base 1. The support leg 2 leaves the ground and cooperates with the moving wheel 5 to facilitate the movement of the spectrometer body 3. The spectrometer body 3 is installed on the placement base 1, and a lateral stabilization component 6 is set on the outside of the spectrometer body 3 on the placement base 1. The lateral stabilization component 6 is operated to abut the spectrometer body 3 from the side, so that the lateral stabilization component 6 limits the spectrometer body 3, thereby preventing the spectrometer body 3 from being disturbed by external factors and causing relative movement to the placement base 1, thereby improving stability.

[0025] like Figure 3 As shown, the supporting moving assembly 4 includes a supporting frame 41, and a bidirectional threaded rod 42 and two secondary threaded rods 43 are rotatably installed inside the supporting frame 41. The two secondary threaded rods 43 are perpendicular to the bidirectional threaded rod 42 and are symmetrically arranged on the left and right. A transmission gear 1 44 is fixedly installed outside the bidirectional threaded rod 42, and the inner sides of the two secondary threaded rods 43 are fixedly connected with a transmission gear 2 45 meshing with the transmission gear 1 44. The front and rear sides of the outside of the bidirectional threaded rod 42 and the outside of the two secondary threaded rods 43 are threadedly connected with a sliding block 47, the bottom of the sliding block 47 is movably hinged with a support rod 48, the bottom of the support rod 48 is movably hinged with a support platform 49, and the moving wheel 5 is fixedly installed at the bottom of the support platform 49.

[0026] The rotation of the bidirectional threaded rod 42 drives the transmission gear 1 44 outside it to rotate, and the transmission gear 1 44 drives the transmission gear 2 45 meshing on both sides thereof to rotate, thereby driving the secondary threaded rods 43 vertically arranged on both sides of the bidirectional threaded rod 42 to rotate synchronously. The thread directions of the front and rear parts of the bidirectional threaded rod 42 are set in opposite directions, and the thread directions of the two external secondary threaded rods 43 are also set in opposite directions, so that the bidirectional threaded rod 42 drives the secondary threaded rod 43 to rotate and drives the sliding block 47 connected to its outside to slide along the support frame 41 to the outside. The sliding block 47 slides outward and drives the support rod 48 to move outward so that the support rod 48 gradually stands up. The support platform 49 is pushed downward by the support rod 48 to gradually prop up the placement base 1, thereby facilitating the movement of the energy spectrometer body 3.

[0027] like Figure 5 As shown, the lateral stabilization assembly 6 includes a fixed block 61, which is fixedly connected to the top of the placement base 1, the internal thread of the fixed block 61 is connected to a clamping screw 62, the outer side of the clamping screw 62 is fixedly connected to a hand wheel 63, and the inner side of the clamping screw 62 is movably installed with a stabilization block 64.

[0028] By rotating the handwheels 63 located on the left and right sides of the spectrometer body 3, the clamping screw 62 is driven to move inward along the fixing block 61. The inward movement of the clamping screw 62 pushes the stabilizing block 64 inside thereof to move inward, so that the stabilizing block 64 is against the outer side of the spectrometer body 3, thereby preventing the spectrometer body 3 from shifting and improving stability.

[0029] like Figure 3 As shown, a limiting block 410 is disposed on the outer side of the support platform 49 , and the limiting block 410 is movably engaged with the interior of the limiting sliding frame 7 .

[0030] The support platform 49 is limited by the limit block 410 located in the limit sliding frame 7 to ensure the stability of the support platform 49 sliding up and down.

[0031] like Figure 3 As shown, the sliding block 47 is located outside the bidirectional threaded rod 42 and the secondary threaded rod 43 and is arranged in a cross shape.

[0032] The slide block 47 arranged in a cross shape slides inward and outward along the bidirectional threaded rod 42 and the secondary threaded rod 43 to cooperate with the support rod 48 to prop up the support platform 49, so as to facilitate the movement of the spectrometer body 3.

[0033] like Figure 3 As shown, a handle 46 is fixedly connected to the rear side of the bidirectional threaded rod 42 and penetrates the supporting leg 2 and is located outside the supporting leg 2 .

[0034] The handle 46 is located outside the supporting leg 2 , and the handle 46 drives the bidirectional threaded rod 42 to rotate, thereby conveniently controlling the lifting and lowering of the moving wheel 5 .

[0035] like Figure 4 As shown, there are four lateral stabilization components 6 in total, and the four lateral stabilization components 6 are arranged in a left-right symmetrical manner based on the spectrometer body 3 .

[0036] Four lateral stabilizing components 6 are symmetrically arranged on the left and right sides of the spectrometer body 3 to clamp and limit the spectrometer body 3 from the side, thereby improving stability.

[0037] like Figure 5 As shown, a connecting sleeve 65 is fixedly connected to the outer side of the stabilizing block 64 , and the connecting sleeve 65 is movably sleeved on the outer side of the clamping screw 62 .

[0038] The connecting sleeve 65 is sleeved on the outside of the clamping screw 62 , and the clamping screw 62 is rotated to push the stabilizing block 64 to slide inwards and abut against the outside of the spectrometer body 3 .

[0039] The working principle of this fully automatic low-background multi-channel gamma spectrometer is described in detail below.

[0040] like Figures 1 to 5As shown, the bidirectional threaded rod 42 connected thereto is driven to rotate by rotating the handle 46, and the transmission gear 1 44 outside the bidirectional threaded rod 42 is driven to rotate by rotating the handle 46, and the transmission gear 2 45 meshed on both sides thereof is driven to rotate by the transmission gear 1 44, thereby driving the secondary threaded rods 43 vertically arranged on both sides of the bidirectional threaded rod 42 to rotate synchronously, and the thread directions of the front and rear parts of the bidirectional threaded rod 42 are set in opposite directions, and the thread directions of the external parts of the two secondary threaded rods 43 are also set in opposite directions, so that the bidirectional threaded rod 42 drives the secondary threaded rod 43 to rotate and drives the sliding block 47 connected thereto to slide from the inside of the support frame 41 to the outside, and the support frame 41 is driven to rotate by the sliding block 47 sliding outward. The support rod 48 moves outward to gradually erect the support rod 48, and the support platform 49 is pushed downward by the support rod 48. The limit block 410 on the side of the support platform 49 is located in the limit slide frame 7 and slides down to make the moving wheel 5 contact the ground to gradually prop up the placement base 1. The moving wheel 5 is used to facilitate the movement of the spectrometer body 3. When the spectrometer body 3 is placed on the placement base 1, the handwheel 63 on the left and right sides of the spectrometer body 3 is rotated to drive the clamping screw 62 to move inward along the fixing block 61. The inward movement of the clamping screw 62 pushes the stabilizing block 64 on its inner side to move inward, so that the stabilizing block 64 is against the outer side of the spectrometer body 3 to prevent the spectrometer body 3 from shifting.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
