Description

Technical Field

[0001] This utility model relates to the field of greenhouse gas detection technology, and in particular to a greenhouse gas detection gas sampler. Background Technology

[0002] A greenhouse gas sampler is a device used to collect and preserve samples of greenhouse gases in the environment. It is usually used in conjunction with a greenhouse gas analyzer or detector for subsequent laboratory analysis or validation. Greenhouse gas samplers include various types such as gas bag samplers, gas cylinder samplers, adsorption tube samplers, and pump samplers.

[0003] However, existing technologies still have shortcomings. Existing greenhouse gas samplers lack protective devices, which leads to multiple maintenance procedures and reduces efficiency.

[0004] Therefore, we propose a greenhouse gas detection gas sampler to solve this problem. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to provide a greenhouse gas detection gas sampler.

[0008] Preferably, the filter includes a mounting shell that is slidably installed on the inner surface of the connecting groove; a first sliding groove is provided on one outer surface of the mounting shell; a second mounting groove is provided on the inner bottom surface of the first sliding groove; a second fixing groove is provided on both sides of the outer surface of the mounting shell; a filter screen is slidably installed on the inner surface of the second mounting groove; and a protective plate is slidably installed on the inner surface of the first sliding groove.

[0009] Preferably, the first fixing device includes a second sliding groove disposed on the outer surface of the outer shell; a fixing frame is slidably installed on the inner surface of the second sliding groove; a first threaded rod is rotatably installed on the outer surface of the fixing frame; a first rotating block is fixedly connected to one end of the first threaded rod; and a guide rod is slidably installed on the inner surface of the fixing frame.

[0010] Preferably, one end of the guide rod is fixed to the outer surface of the housing; one end of the first threaded rod is movably mounted on the inner surface of the housing.

[0011] Preferably, the second fixing device includes a third sliding groove disposed on the inner surface of the outer shell; a fixing block is slidably installed on the inner surface of the third sliding groove; a second threaded rod is movably installed on one outer surface of the fixing block; and a second rotating block is fixedly connected to one end of the second threaded rod.

[0012] Preferably, the fixing block and the second fixing groove cooperate with each other; the second threaded rod is rotatably installed on the inner surface of the outer shell.

[0013] In this utility model, a greenhouse gas detector sampler is provided. Through the arrangement of a shell, a first mounting slot, an inner frame, a gas collector body, a mounting bracket, a pressure plate, a first fixing slot, a second sliding groove, a fixing frame, a first threaded rod, a first rotating block, and a guide rod, when repairing the gas collector body, rotating the first rotating block causes the first threaded rod to rotate, which in turn moves the fixing frame away from the second sliding groove. This allows the mounting bracket to be removed from the first mounting slot, and the gas collector body to be removed from the shell. This allows for quick installation and disassembly of the gas collector body, and also enables rapid repair, thus improving efficiency.

[0014] In this utility model, a greenhouse gas sampler for detection, through the arrangement of a mounting shell, a second fixing groove, a first sliding groove, a second mounting groove, a filter screen, a protective plate, a third sliding groove, a fixing block, a second threaded rod, and a second rotating block, allows for quick filter maintenance. Rotating the second rotating block rotates the second threaded rod, which in turn moves the fixing block away from the second fixing groove, allowing the filter to be removed from the connecting groove. Then, the protective plate is removed from the mounting shell, and finally, the filter screen can be removed from the second mounting groove for replacement. This enables rapid filter maintenance, prevents the gas sampler body from being clogged by dust and debris, and reduces the frequency of maintenance.

[0015] This utility model has a reasonable structural design, is simple to operate, and has high reliability. Attached Figure Description
