Description

Technical Field

[0001] The utility model relates to the technical field of integrated samplers, and in particular to a high negative pressure intelligent integrated sampler capable of reducing vibration. Background Art

[0002] A high negative pressure intelligent integrated sampler is a device used to collect particles and gases in the atmosphere. It usually has a high negative pressure exhaust system that can draw particles and gases in the atmosphere into the sampler and separate and collect them through filters or adsorbents. At the same time, the high negative pressure intelligent integrated sampler is also equipped with an intelligent control system and data acquisition system, which can monitor various parameters in the sampling process in real time, such as temperature, humidity, pressure, flow, etc., and record the data for subsequent data analysis and processing.

[0003] The existing high negative pressure intelligent integrated samplers have poor shock absorption and protection performance. When the sampler is subjected to strong external vibration or collision, it is easy to cause damage to the internal components of the sampler, reducing the service life of the sampler. In addition, when sampling, vibration may cause errors in the sampling process, thereby affecting the accuracy of the sampling results. Utility Model Content

[0004] In view of the above shortcomings, the utility model provides a high-negative pressure intelligent integrated sampler that can reduce vibration, can dampen the sampler, and can adjust the level of the sampler so that the sampler is in a better state to work, thereby avoiding affecting the sampling results of the sampler.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high negative pressure intelligent integrated sampler capable of reducing vibration comprises a collector, wherein a base is provided at the bottom of the collector, a plurality of support rods are provided on the base, the base is connected to a shock absorbing platform via the support rods, a shock absorbing mechanism is provided on the support rods and is located between the base and the shock absorbing platform, a plurality of driving mechanisms are provided in the shock absorbing platform, the driving mechanisms are connected to the support rods, and the driving mechanisms are fixedly installed in the shock absorbing platform via a rebound mechanism.

[0007] Through the above scheme, the shock absorbing mechanism can absorb the vibration of the base, thereby absorbing the vibration of the sampler, and the level of the base can be adjusted through the driving mechanism, and the shock absorbing rate of the shock absorbing mechanism can also be adjusted.

[0008] Furthermore, a shock absorbing groove is provided at the bottom of the base around the support rod, a rubber pad is provided at the bottom of the shock absorbing groove, a limiting plate is provided at the bottom of the support rod, and a thread is provided on the circumference of one end of the support rod provided with the limiting plate.

[0009] Through the above further solution, the distance between the base and the shock absorbing platform can be reduced, the stability can be improved, and the rubber pad can play a buffering role as well as a protective role.

[0010] Furthermore, the shock-absorbing platform is provided with sliding grooves corresponding to the support rods, the number of the sliding grooves is the same as the number of the support rods, the support rod is provided with a limit plate at one end which is slidably connected in the sliding groove, one side of the sliding groove is provided with an expansion groove for placing the driving mechanism, and the expansion groove is provided with groove bodies for installing the rebound mechanism on both opposite sides.

[0011] Furthermore, the shock absorbing mechanism is a shock absorbing spring, which is sleeved on the support rod, with one end of the shock absorbing spring abutting against the rubber pad in the shock absorbing groove and the other end abutting against the upper side of the shock absorbing platform.

[0012] Through the above further solution, the shock-absorbing spring can reduce the shock of the base.

[0013] Furthermore, the driving mechanism includes a worm wheel and a worm, the inner ring of the worm wheel is provided with a thread, the inner ring of the worm wheel is threadedly connected to the support rod with one end provided with a thread, the outer ring of the worm wheel is meshingly connected to the worm, and both ends of the worm are fixedly connected to the rebound mechanism through bearings.

[0014] According to the above further solution, the worm gear is rotated by rotating the worm, and the direction in which the worm gear rotates can cause the support rod to rise or fall, thereby adjusting the level of the base.

[0015] Furthermore, the rebound mechanism includes a slider and a first spring, the slider is slidably connected in the groove body, one end of the slider is provided with an arc groove fixedly connected to the bearing, and the other end is provided with a first connecting rod fixedly connected to one end of the first spring, and a second connecting rod is provided on the side opposite to the first connecting rod of the groove body and the slider, and the second connecting rod is fixedly connected to the other end of the first spring.

[0016] Through the above further scheme, the slider can slide in the groove body so that the worm can move. When the sampler is vibrated, the support rod drives the worm wheel to move up and down, and the worm wheel can disengage from the meshing connection of the worm and move. After the vibration, the first spring pushes the slider to move, and the slider pushes the worm to move, causing the worm to mesh with the worm wheel.

[0017] Furthermore, a socket is provided on the groove body near the outer side of the shock absorbing platform, and the socket passes through the shock absorbing platform to the outer side.

The rotating handle with one end of the block is inserted into the socket from the outside of the shock-absorbing platform and is engaged with the slot and is rotatably connected to the socket.

[0019] Through the above further solution, the worm can be rotated by rotating the handle, and the rotation of the worm causes the support rod to rise or fall, thereby adjusting the base.

[0021] Through the above further scheme, when the block of the rotating handle is inserted into the slot of the worm, the block moves the limit rod inward, so that the limit rod is inserted into the limit hole, and cooperates with the rotating handle in the insertion hole to fix the worm, so that the worm is always engaged with the worm wheel. At this time, the worm can be rotated by the rotating handle to adjust the base.

[0022] Furthermore, the bottom of the shock absorbing platform is provided with supporting feet, and the supporting feet are provided with buffer pads.

[0023] Through the above further solution, the buffer pad can play a role in buffering and shock absorption, and further reduce the shock of the sampler.

[0024] Compared with the prior art, the beneficial effects of the utility model are that the sampler can be damped by the damping mechanism, the sampler on the base can be adjusted horizontally by the cooperation between the driving mechanism and the support rod, and the cooperation between the support rod and the driving mechanism does not affect the damping effect through the rebound mechanism.
