Description

Portable constant-current gas sampler Technical Field The utility model relates to the technical field of constant-current gas samplers, in particular to a portable constant-current gas sampler. Background In use, the constant-flow gas sampler takes the air pump as sampling power (a positive-displacement vane pump and other powerful pumps possibly manufactured by an inlet DC brushless motor are adopted), the air pump pumps air into a sampling bottle for a certain time with constant flow through the air pump, and the pumping pressure is high, the flow is stable and the running time is long). After entering the sampler, the air passes through the relevant air path structure, and may involve a device similar to a constant flow maintaining unit. In some designs of constant flow samplers, the air flow output by the air source module enters a specific structure (such as a large-diameter shell at the upper end of a conical piston) through an air guide hose, then enters a small-diameter shell through a gap between the conical piston and other components, and then is input into an air sampling bottle. The conical piston can automatically adjust the position under the action of air pressure and spring force, when the air pressure in the large-diameter shell and the spring force of the cylindrical spring are balanced, the position of the conical piston is constant, so that the air quantity entering the small-diameter shell is constant, and the air quantity entering the sampling bottle is further ensured to be constant. If the air quantity is too large, the pressure rises to a set value, the overflow valve can be automatically opened for pressure relief, and the constant flow is ensured. After the harmful components in the air fully react with the detection solution in the sampling bottle, the reacted solution is sent to a detector for detection, so that detection results of the concentration of the related gas components and the like are obtained. For example, although the constant-current gas sampler with the model number ZD-1013 of the Utility meter is convenient to carry through the box body and the handle, the constant-current gas sampler can appear in the actual use process, and the center of gravity of a product is distributed unreasonably due to the rear-mounted battery, so that the hand-held constant-current gas sampler is easy to cause arm ache for a long time, and the portable constant-current gas sampler is needed to solve the problems. Disclosure of utility model The utility model aims to provide a portable constant-current gas sampler, which solves the problems that the constant-current gas sampler with the model ZD-1013 in the prior art is convenient to carry through a box body and a handle, but in the actual use process, the gravity center distribution of a product is not reasonable enough due to the rear arrangement of a battery, and arm ache is easily caused by long-time handheld. The portable constant-current gas sampler comprises a movable seat, wherein the bottom end of the movable seat is fixedly connected with a plurality of movable wheels, the side end of the movable seat is fixedly connected with a handle, the top end of the movable seat is provided with a straight groove, a rotating assembly is arranged in the straight groove, the outer end of the rotating assembly is provided with a clamping assembly, a constant-current gas sampler body is arranged in the clamping assembly, the side end of the movable seat is provided with a rectangular groove, and a limiting assembly for fixing the rotating assembly is arranged in the rectangular groove.
