Description

Technical Field

[0001] This utility model relates to the field of environmental sampling, specifically an impact-resistant environmental sampler. Background Technology

[0002] Environmental sampling refers to the process of accurately obtaining the spatial distribution and temporal changes of pollutants, nutrients, or other target analytes in environmental media during scientific research, environmental monitoring, or regulatory assessment. Following established technical specifications and sampling plans, and considering the sampling objectives and monitoring requirements, representative sampling points, depths, or heights are selected. Depending on timeframes or continuous sampling needs, manual or automated sampling equipment is used. On-site sampling or quantitative interception is implemented according to principles of sample preservation, low-temperature storage, and chain management. Through sample container cleaning, disinfection, and labeling management, cold chain transportation of samples, and laboratory pretreatment processes, the integrity of the samples is ensured, preventing secondary contamination and loss. Quality assurance and quality control measures are then used to verify the reliability of the data. Throughout the process, topography, seasonal climate, and on-site environmental conditions are comprehensively considered, on-site parameters are monitored, and data quality is evaluated. Finally, standardized environmental sample information archives and data reports are generated, providing reliable technical support for long-term environmental trend analysis, pollution control strategy formulation, and emergency response to sudden environmental incidents.

[0003] During movement or carrying in the field and confined environments, environmental samplers are often subjected to external impacts, which can cause deformation or cracking of the outer shell structure, failure of the sample container seal, resulting in sample leakage or cross-contamination. This not only seriously reduces sampling accuracy and data reliability, but also increases the frequency of device maintenance, affects monitoring efficiency, and poses safety hazards. Based on this, this utility model designs an impact-resistant environmental sampler to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-7 The impact-resistant environmental sampler in this embodiment includes an environmental sampler body 1, a swing arm suspension mechanism 2, a pluggable energy absorption mechanism 3, and a cover plate 4.

[0021] I. Environmental Sampling Device 1 The environmental sampler body 1 is the main structure of this invention, used to house key components such as the internal sampling pump, filter head, and sensor, and a swing arm suspension mechanism 2 is fixed on its left and right sides respectively. The outer wall of the environmental sampler body 1 is provided with a first bearing sleeve 201 and a preset slot.

[0022] II. Swing rod suspension mechanism 2 The swing arm suspension mechanism 2 includes: The first bearing sleeve 201 is fixed to the outer wall of the environmental sampler body 1; The first bearing body 202 is fitted into the middle of the first bearing sleeve 201 and is engaged with one end of the rotating shaft 203; The rotating shaft 203 is fixedly connected to the lower end of the rocker arm body 204, and the other end is connected to the first bearing body 202; The lower end of the swing arm body 204 is fixed with the rotating shaft 203, and the upper end is connected to the first mounting bracket 205. The first mounting bracket 205 is fixedly connected to the outside of the second bearing body 206; The second bearing body 206 is fitted into the middle of the second bearing sleeve 207; The second bearing sleeve 207 is fixedly mounted on the lower end of the second mounting bracket 208; The second mounting bracket 208 mates with the third bearing body 209; The third bearing body 209 is fitted into the middle of the third bearing sleeve 210; The third bearing sleeve 210 is fixed to the inner wall of the PC protective cover 301.

[0023] In use, an external impact causes the first bearing body 202 to drive the rotating shaft 203 and the swing arm 204 to swing back and forth. The first mounting bracket 205 drives the second bearing body 206 to swing left and right in the second bearing sleeve 207, and then swings left and right again in the third bearing sleeve 210 through the second mounting bracket 208 and the third bearing body 209. Through the above multi-stage swinging, mechanical energy is converted step by step and dissipated by friction bushings, thereby significantly reducing the impact force transmitted to the environmental sampler body 1.

[0024] III. Plug-in Energy Absorption Mechanism 3 The pluggable energy absorption mechanism 3 includes a PC protective cover 301, a rubber pad 302, a socket 303, a first reset spring 304, a first limit block 305, a first stop block 306, a second reset spring 307, a second limit block 308, and a second stop block 309.

[0025] PC protective cover 301 is placed on the outside of the environmental sampler body 1, with a third bearing sleeve 210 fixed on its inner wall and a cover plate 4 at the top, which serves as the first rigid protection.

[0026] The socket 303 is inserted into the preset slot of the PC protective cover 301, and one end of it is fixed with a rubber pad 302 for direct contact with the outside world and initial cushioning.

[0027] A first reset spring 304 is installed at the lower end of the socket 303. The bottom end of the first reset spring 304 is connected to a first limiting block 305. A first abutment 306 is provided below the first limiting block 305. A second reset spring 307 is installed at the upper end of the socket 303. The top end of the second reset spring 307 is connected to a second limiting block 308. A second abutment 309 is provided on the outside of the second limiting block 308.

[0028] When subjected to force, the rubber pad 302 undergoes viscoelastic deformation, absorbing the high-amplitude instantaneous impact energy through friction and internal heat dissipation. After the impact, the first return spring 304 and the second return spring 307 push the limit block to reset, keeping the rubber pad 302 stable in the predetermined position. Pressing the first stop block 306 and the second stop block 309 compresses the corresponding return spring and releases the limit block, enabling quick disassembly and replacement of the socket 303 and its rubber pad 302.

[0029] IV. Comprehensive Work Process When the environmental sampler body 1 is impacted, the PC protective cover 301 first absorbs part of the impact. Then, the impact force is transmitted to the swing arm suspension mechanism 2 through the third bearing sleeve 210. The energy is dissipated by the back-and-forth and left-and-right swing of the multi-stage bearings and mounting bracket. At the same time, the rubber pad 302 achieves viscoelastic buffering under the action of the socket 303, and maintains its position and quickly resets with the help of the return spring and limit block. The two mechanisms work together to effectively protect the internal filter head, sensor and pump from impact damage, and ensure sampling accuracy and equipment reliability.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
