Description

Technical Field

[0001] The utility model belongs to the field of shock absorption of mass spectrometers, and relates to an enclosed shock absorption system, which is applicable to the shock absorption of an inductively coupled plasma mass spectrometer (ICP-MS) during movement, so that the instrument in the standby state can be quickly powered on and operated after experiencing various transportation conditions. Background Art

[0002] ICP-MS is widely used in inorganic detection as a precision analytical instrument and can be used to simultaneously detect multiple metal elements. The installation and debugging process of ICP-MS is complex and requires high precision. It takes a long time from installation and debugging to reaching the vacuum environment required for analytical testing. When an emergency occurs, for example, when a hazardous chemical leaks and it is necessary to quickly reach the scene for analysis and detection, the standby ICP-MS needs to be installed on a transportation vehicle, such as various vehicles, ships, helicopters, etc., and reach the scene with the transportation vehicle to quickly carry out analytical testing work. The impacts and vibrations from all directions encountered during transportation may damage the instrument and affect its sensitivity and stability.

[0003] Mechanically speaking, impact is an instantaneous and intense large acceleration force, and vibration is a relatively long-term small acceleration force. During transportation and movement, impacts and vibrations may come from any direction. Conventional shock absorption systems usually focus on shock absorption in one direction or two directions, and cannot take into account multi-directional shock absorption, or the shock absorption effect is not good. Therefore, a shock absorption system is needed that can reduce or eliminate impacts and vibrations from all directions to reduce the adverse effects on ICP-MS during transportation.

[0004] In view of the above problems, the utility model provides an enclosed shock absorption system, which can well absorb impacts and vibrations from all directions and is used for the shock absorption of ICP-MS installed on various transportation vehicles. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an enclosed shock absorption system, including a main shock absorption unit and an auxiliary shock absorption unit. This shock absorption system can absorb impacts and vibrations from all directions and can be well used for the shock absorption of instruments such as ICP-MS in a moving state, for example, ICP-MS installed on various transportation vehicles such as vehicles, ships, and even helicopters, so as to ensure that ICP-MS can smoothly reach the designated site and carry out analytical testing work.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] An enclosed shock absorption system, characterized in that: the shock absorption system includes a main shock absorption unit and an auxiliary shock absorption unit, wherein the main shock absorption unit includes an outer frame, a middle frame, an inner frame and shock absorbers, and the auxiliary shock absorption unit includes a plurality of shock absorbers.

[0008] The outer frame is composed of a bottom plate, a left side plate and a back plate. Screw holes are opened at the edges of the bottom plate, the left side plate and the back plate, and they can be fixed on the transportation tool through bolts; a lifting ring is installed on the bottom plate for convenient lifting.

[0009] The inner frame is an upper bottom plate, which can be fixed by connecting with the instrument bottom plate through bolts.

[0010] The middle frame is composed of an intermediate plate, a middle back plate and a left middle plate.

[0011] Shock absorbers are provided on the upper side of the intermediate plate. The shock absorbers are horizontally installed along the length direction of the intermediate plate (as the X direction), and are called X-direction shock absorbers; shock absorbers are provided on the lower side of the intermediate plate. The shock absorbers are longitudinally installed along the width direction of the intermediate plate (as the Y direction), and are called Y-direction shock absorbers; the intermediate plate is connected to the bottom surface of the upper bottom plate through the X-direction shock absorbers and to the top surface of the bottom plate through the Y-direction shock absorbers.

[0012] The X-direction shock absorbers are evenly distributed on the intermediate plate; the number is selected according to needs. For example, it can be 9, distributed in 3 rows and 3 columns; or 16, distributed in 4 rows and 4 columns; more can also be used.

[0013] The Y-direction shock absorbers are evenly distributed on the intermediate plate; the number is selected according to needs. For example, it can be 9, distributed in 3 rows and 3 columns, or 16, distributed in 4 rows and 4 columns; more can also be used.

[0014] The Y-direction shock absorbers and the X-direction shock absorbers can absorb impacts and vibrations in the height direction (the direction perpendicular to the X direction and the Y direction, abbreviated as the Z direction).

[0015] Shock absorbers are provided on the middle back plate, called back-mounted shock absorbers. The middle back plate is connected to the back plate through the back-mounted shock absorbers to absorb impacts and vibrations in the Y direction. The back-mounted shock absorbers are evenly distributed on the middle back plate, and the number can be selected according to needs. Preferably, it is 6, distributed in 3 rows and 2 columns, and can also be 9 or more.

[0016] Shock absorbers are provided on the left middle plate, called side-mounted shock absorbers. The left middle plate is connected to the left side plate through the side-mounted shock absorbers to absorb impacts and vibrations in the X direction. The side-mounted shock absorbers are evenly distributed on the left middle plate, and the number can be selected according to needs. Preferably, it is 6, distributed in 3 rows and 2 columns, and can also be 9 or more.

[0017] The shock absorber of the main shock absorbing unit is composed of a Y-direction shock absorber, an X-direction shock absorber, a side-mounted shock absorber and a back-mounted shock absorber, which can be selected from a wire rope shock absorber and a spring shock absorber.

[0018] The auxiliary shock absorbing unit can be a cone-type rubber shock absorber or a spring shock absorber, preferably a cone-type rubber shock absorber. The number of shock absorbers can be selected as needed, such as 6, 7, 8, 9, 10, of which some (such as 2, 3 or 4) are fixed on the top of the middle back plate and connected to the back of the instrument housing, and some (such as 4 or 6) are fixed on the upper middle part of the left middle plate and connected to the left side of the instrument housing.

[0019] ICP-MS products are relatively large in size, especially high in height, and are only fixed by the bottom plate. When subjected to XY distance impact and vibration, the top of the ICP-MS is prone to large shaking due to the whip effect, so an elastic structure is required on the top to prevent it from large shaking. The auxiliary shock absorbing unit of the shock absorbing system of the utility model can prevent the top from large shaking when the ICP-MS is subjected to strong impact from the X and Y directions; when the ICP-MS is subjected to vibration from the X and Y directions, low-frequency weak vibrations are absorbed.

[0020] The enclosed shock absorbing system of the utility model can also be used for shock absorbing of other instruments on transportation vehicles.

[0021] The ICP-MS surround shock absorption system of the utility model has a reasonable structure and a novel design, can effectively absorb the impact and vibration from the XYZ directions, and is well used for shock absorption of ICP-MS installed on various vehicles, ships, helicopters and other transportation tools, so that the ICP-MS can be transported to the designated site in a standby state and immediately carry out analysis and testing work.

[0031] The following further details the enclosed shock absorption system of the present utility model with reference to the attached Figure 1 -5 through embodiments. The embodiments are only illustrative and by no means limit the implementation manner. Different forms of changes or variations made by those of ordinary skill in the art based on the said embodiments, as well as the obvious changes or variations derived therefrom, all fall within the protection scope of the present utility model.

[0032] An enclosed shock absorption system includes a main shock absorption unit and an auxiliary shock absorption unit; the main shock absorption unit consists of outer, middle, and inner three-layer frames and shock absorbers; the auxiliary shock absorption unit consists of 6 conical rubber shock absorbers.

[0033] As Figure 1 shown, the outer layer frame of the main shock absorption unit consists of a bottom plate (1), a left side plate (2), and a back plate (3). The bottom plate (1) is equipped with a lifting ring (13) for easy hoisting; evenly distributed screw holes (14) are opened at the edges of the bottom plate (1), the left side plate (2), and the back plate (3), and they can be fixed on the transportation tool through bolts. The middle layer frame consists of a middle plate (4), a middle back plate (5), and a left middle plate (6); the inner layer frame consists of an upper bottom plate (7), which is connected and fixed to the bottom plate of the ICP-MS.

[0034] As Figures 1 - 3 shown, the middle plate (4) is connected to the bottom surface of the upper bottom plate (7) through 3 rows and 3 columns of evenly distributed X-direction shock absorbers (9) arranged on its upper side, and is connected to the top surface of the bottom plate (1) through 3 rows and 3 columns of evenly distributed Y-direction shock absorbers (8) arranged on its lower side.

[0035] As Figure 1As shown in Fig. 4, there are side-mounted shock absorbers (10) evenly distributed in 3 rows and 2 columns on the left middle plate (6), and the left middle plate (6) is connected to the left side plate (2) through the side-mounted shock absorbers (10).

[0036] When the bottom plate (1) and the left side plate (2) fixed on the transportation vehicle are subjected to impacts and vibrations in the X direction, the X-direction shock absorbers (9) and the side-mounted shock absorbers (10) undergo elastic displacement deformation, and at the same time act to absorb the forces in the X direction, thereby reducing the impacts and vibrations received by the left middle plate (6) and the upper bottom plate (7).

[0037] As Figure 1 As shown in Fig. 5, there are back-mounted shock absorbers (11) evenly distributed in 3 rows and 2 columns on the middle back plate (5), and the middle back plate (5) is connected to the back plate (3) through the back-mounted shock absorbers (11).

[0038] When the bottom plate (1) and the back plate (3) fixed on the transportation vehicle are subjected to impacts and vibrations in the Y direction, the Y-direction shock absorbers (8) and the back-mounted shock absorbers (11) undergo elastic displacement deformation, and at the same time act to absorb the forces in the Y direction, thereby reducing the impacts and vibrations received by the middle back plate (5) and the upper bottom plate (7).

[0039] When subjected to impacts and vibrations in the Z direction, the Y-direction shock absorbers (8) and the X-direction shock absorbers (9) are compressed and deformed to absorb the forces in the Z direction, thereby reducing the impacts and vibrations received by the upper bottom plate (7).

[0040] Thus, the impacts and vibrations from the X - Y - Z directions are all reduced.

[0041] The auxiliary shock absorption unit includes 6 conical rubber shock absorbers (12), among which 2 are fixed on the top of the middle back plate (5) and connected to the back of the ICP - MS housing, and 4 are fixed in the upper middle part of the left middle plate (6) and connected to the left side of the ICP - MS housing.

[0042] When the ICP - MS fixed on the upper bottom plate (7) is subjected to strong impacts in the X direction and the Y direction, the conical rubber shock absorbers (12) are deformed to provide a force in the direction opposite to the impact direction at the top of the ICP - MS, and the impact effect is weakened, thereby avoiding large - amplitude shaking at the top of the ICP - MS; when the ICP - MS fixed on the upper bottom plate (7) is subjected to vibrations, the conical rubber shock absorbers (12) are deformed to absorb the low - frequency weak vibrations conducted from the middle back plate (5) and the left middle plate (6), thereby avoiding damage to the top of the ICP - MS housing due to resonance.

[0043] As Figure 6As shown in the figure, the shock absorption system of the present utility model is applied to an ICP-MS, and the shock absorption effect is measured by conducting shock tests, random vibration tests, and sine vibration tests respectively. The ICP-MS is the A-type ICP-MS of Hengsheng Mass Spectrometry (Beijing) Instrument Co., Ltd., and the instrument parameters are as follows: overall dimensions: 1008x698x605 mm (length x depth x height), weight about 180 kg; the center of gravity position of the ICP-MS: 500x380x300 mm, where the length direction of the ICP-MS is the X direction, the depth direction is the Y direction, and the height direction is the Z direction.

[0044] 1. Shock test

[0045] Semi-sine shock tests are conducted in the X-Y-Z three directions respectively with a pulse period of 11 ms and a peak shock value of 196 m / s² (20 g) acceleration. After passing through this shock absorption system, the acceleration of 20 g is approximately 0.

[0046] 2. Random vibration test

[0047] Random vibration tests are conducted in the X-Y-Z directions according to the power spectral density for 10 minutes in each direction. The anti-vibration effect is significant for vibrations with frequencies above 15 Hz.

[0048] 3. Sine vibration test

[0049] Resonance searches are conducted for 15 minutes in each of the X-Y-Z directions, each direction is cycled for 15 minutes, and resonance is maintained for 10 minutes in each direction. The peak amplitude is 0.33 mm, and the resonance frequencies in the X-Y-Z directions are 33.34 Hz, 36.81 Hz, and 38.42 Hz respectively. The test results are good, and the ICP-MS can work normally.
