[0003] Some existing cyclotron oscillators have a protective cover fixed on the upper end of the oscillation platform, and the protective cover is detachably connected to the oscillation platform.

When the oscillating sample changes, the size of the protective cover needs to be adjusted. For the laboratory of the Ecological Environment Monitoring Center, it is necessary to prepare multiple protective covers of different sizes, and the protective covers need to be disassembled and installed before oscillation, which reduces the efficiency of reagent oscillation.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] See attached Figure 1 -Attached Figure 5 A cyclotron oscillator includes an oscillation device 100, which includes an oscillation base 110 and an oscillation platform 120 installed on the upper end of the oscillation base 110. A heat preservation device 200 is installed on the upper end of the oscillation platform 120. The heat preservation device 200 can heat and keep the reagent on the surface of the oscillation platform 120. A heating wire can be installed in the heat preservation device 200 to provide a heat source to maintain the reagent oscillation at a suitable temperature to meet the oscillation requirements of a specific reagent at a constant temperature.

[0026] Some existing cycloidal oscillators have a protective cover fixed on the upper end of the oscillation platform 120, and the protective cover is detachably connected to the oscillation platform 120. During the oscillation process, the protective cover moves and oscillates synchronously with the reagent bottles inside; however, for reagent bottles of higher and larger sizes, the protective cover needs to be high and large enough. For reagent bottles of large sizes, while increasing the oscillation load of the oscillation device 100, the instability of the entire equipment is increased; in addition, during the actual oscillation processing process, reagent bottles of different numbers and sizes need to be oscillated. When the oscillated sample changes, the size of the protective cover needs to be adjusted. For enterprises, it is necessary to prepare multiple protective covers of different sizes, and the protective covers need to be disassembled and installed before oscillation, which reduces the efficiency of reagent oscillation.

[0027] In order to solve the above problems, the improved heat preservation device 200 includes a plurality of arc-shaped first heat preservation sheets 210 and a plurality of arc-shaped second heat preservation sheets 220, the first heat preservation sheets 210 and the second heat preservation sheets 220 are alternately arranged, the second heat preservation sheets 220 are movably connected to the first heat preservation sheets 210, and the plurality of first heat preservation sheets 210 and the second heat preservation sheets 220 are enclosed to form a heat preservation chamber, and the first heat preservation sheets 210 and the second heat preservation sheets 220 can be slidably connected to each other; Figure 5 As shown, two first insulation sheets 210 and a second insulation sheet 220 are selected as an example; during the adjustment process, the size of the insulation chamber can be adjusted by pulling or pushing the two first insulation sheets 210 to enclose insulation chambers of different sizes, thereby satisfying the adaptive oscillation processing of reagent bottles of different numbers and sizes.

[0028] The first thermal insulation sheet 210 and the second thermal insulation sheet 220 here can be made of thermal insulation materials, and can be selected as elastic arc-shaped sheets for easy installation. The first thermal insulation sheet 210 and the second thermal insulation sheet 220 can be enclosed to form a cylindrical thermal insulation area to meet the reagent oscillation requirements.

[0029] An adjusting device 300 is installed above the insulation device 200, and the adjusting device 300 is used to control the overlapping area of ​​the first insulation sheet 210 and the second insulation sheet 220, as well as the position of the insulation chamber. The position and size of the insulation chamber can be adjusted according to the position of the reagent's cyclotron oscillation. It can be determined that when the rotation axis of the oscillation platform 120 is determined, the axis of the virtual cylinder formed by the first insulation sheet 210 and the second insulation sheet 220 is consistent with the rotation axis of the oscillation platform 120. The reagent makes a circular motion in the insulation chamber and will not collide with the inner walls of the first insulation sheet 210 and the second insulation sheet 220, thereby ensuring the stability of the overall structure.

[0030] Through the above-mentioned structural design, the first insulation sheet 210 and the second insulation sheet 220 are installed through the adjustment device 300, and will not oscillate synchronously with the oscillation platform 120, thereby reducing the load of the oscillation of the oscillation platform 120 and reducing the probability of overall tilting; at the same time, the size of the insulation chamber formed by the first insulation sheet 210 and the second insulation sheet 220 can be adjusted to meet the oscillation requirements of reagent bottles of different numbers and sizes, thereby improving the efficiency of the oscillation of the reagent bottles.

[0031] It should also be noted that the top of the adjusting device 300 is relatively sealed, which can play a good role in heat insulation; at the same time, the heating wire is installed in the first insulation plate 210 and the second insulation plate 220, and the external power supply can adjust the temperature in the insulation chamber to maintain a predetermined constant temperature state; and the adjusting device 300 here can be connected to a lifting device or a suspension device to realize automatic lifting of the adjusting device 300 and the insulation device 200, which is convenient for the staff to place the reagent bottle on the surface of the oscillation platform 120 from the bottom to meet the requirements of cyclotron oscillation.

[0032] An installation opening is opened on the side wall of the first insulation sheet 210, and the second insulation sheet 220 is located in the installation opening and is movably connected to the first insulation sheet 210. The first insulation sheet 210 and the second insulation sheet 220 partially overlap, and the first insulation sheet 210 and the second insulation sheet 220 brackets can form a sealed chamber with a U-shaped cross-section, thereby improving the sealing of the overall structure and the stability during the adjustment process.

[0033] Furthermore, a first installation opening 211 is opened on the first side wall of the first insulation sheet 210, and a second installation opening 212 is opened on the second side wall of the first insulation sheet 210. The first installation opening 211 and the second installation opening 212 are staggered with each other. At this time, the second insulation sheet 220 has a larger movable area, and the insulation chamber has a larger adjustable size range, which can meet the simultaneous cyclotron oscillation requirements of more reagent bottles.

[0034] Please refer to the attached Figure 4 Specifically, the adjustment device 300 includes a sealing plate 360, and the first thermal insulation sheet 210 and the second thermal insulation sheet 220 are in contact with the bottom surface of the sealing plate 360 ​​and are movably connected to the sealing plate 360. An adjustment component is provided at the bottom of the sealing plate 360 ​​for adjusting the distance between the two first thermal insulation sheets 210. The first thermal insulation sheet 210 and the second thermal insulation sheet 220 can be movably located at the bottom of the sealing plate 360 ​​and can be slidably connected through a sliding connector. At the same time, the distance between the two first thermal insulation sheets 210 can be adjusted by the adjustment component, thereby realizing the adjustment of the positions of the two second thermal insulation sheets 220 and realizing the adjustment and control of the size of the thermal insulation chamber.

[0035] The adjustment component here can be selected as an existing adjustment element, such as a telescopic rod, a threaded rod, etc., or a combination of manual adjustment and a locking buckle can be selected; the adjustment element here is placed on the outside of the insulation chamber and does not occupy the area inside the insulation chamber to avoid interference and collision with the reagent bottle.

[0036] A positioning plate 320 is arranged above the sealing plate 360, and a transverse sliding joint and a longitudinal sliding joint are installed between the positioning plate 320 and the sealing plate 360. The position of the sealing plate 360 ​​can be adjusted through the transverse sliding joint and the longitudinal sliding joint, and then the position of the insulation device 200 and the insulation chamber can be adjusted. The position of the insulation chamber can be calibrated and positioned according to the installation position of the positioning plate 320, so that the trajectory of the gyratory oscillation of the oscillation platform 120 is the same as the inner diameter of the insulation chamber, which can minimize the area of ​​the insulation chamber and enhance the insulation effect in the insulation chamber.

[0037] Specifically; the longitudinal sliding joint includes a first guide rail 340, the transverse sliding joint slides along the first guide rail 340, the transverse sliding joint includes a second guide rail 330, a slider 350 slides at the bottom of the second guide rail 330, and the bottom of the slider 350 is fixedly connected to the upper end of the sealing plate 360. The above-mentioned second guide rail 330, first guide rail 340 and other structures can be selected as damping structures, which can adjust the damping and self-lock to a certain extent to ensure the stability of the overall structure.

[0038] A positioning seat 310 is fixed on the upper surface of the positioning plate 320, and a positioning opening is opened on the side wall of the positioning seat 310. The positioning opening can be connected to a lifting device or a suspension device to realize automatic adjustment of the height of the adjusting device 300 and the insulation device 200, thereby further improving the efficiency of the reagent cyclotron oscillation.

[0039] Furthermore, sealing airbags are respectively fixed at the bottom of the first insulation sheet 210 and the second insulation sheet 220, and the sealing airbags are externally connected to an air pump device. The sealing airbags here expand toward the oscillation platform 120, which can enhance the sealing effect of the bottom of the first insulation sheet 210 and the second insulation sheet 220. It should be noted here that the expansion size of the sealing airbags here needs to be adjusted according to the position of the insulation device 200, and the sealing airbags should avoid contact with the upper end of the oscillation platform 120.

[0040] When the utility model is used, the heat preservation device 200 is lifted, and the reagent bottle is placed at the center position of the upper end of the oscillation platform 120 and locked; after the oscillation platform 120 is locked and positioned, the heat preservation device 200 is sleeved on the outside of the reagent bottle, and the position of the heat preservation device 200 is adjusted so that the axis of rotation of the reagent bottle is consistent with the axis of the heat preservation device 200; the heat preservation device 200 is controlled to be in a predetermined constant temperature state, and the oscillation platform 120 is driven to oscillate in rotation, thereby realizing the rotation oscillation of the reagent bottle under constant temperature.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
