The sampling device according to the embodiment of the invention comprises: support tube 300, flexible sampling tube 400, heating element 700, temperature control element 600.

Referring to fig. 5 to 6, the support tube 300 is formed by splicing a plurality of support sub-tubes 310, and the interior of the support tube is a hollow structure through which the flexible sampling tube 400 can be placed in the support tube 300. When sampling, because the accuracy of sampling needs to be guaranteed, the support tube 300 will be stretched out to the input of flexible sampling tube 400 usually, and likewise, in order to ensure that the gas of sampling can be conducted out of the support tube 300 and can not be attached to the support tube 300, the support tube 300 will also be stretched out to the output of flexible sampling tube 400, that is to say, both ends of flexible sampling tube 400 will stretch out of the support tube 300. In addition, in order to ensure that the flexible sampling tube 400 can be better arranged in the support tube 300 in a penetrating manner, a certain gap is kept between the inner wall of the support tube 300 and the flexible sampling tube 400, so that the situation that the flexible sampling tube 400 is difficult to install and even the flexible sampling tube 400 is worn due to excessive resistance is prevented. The heating member 700 is used for heating the flexible sampling tube 400, and in order to ensure the heating effect on the whole section of the flexible sampling tube 400, the heating member 700 is usually selected to have a certain length so as to avoid that a part of the area is not heated. In some embodiments of the present invention, the heating element 700 may also be comprised of a plurality of heating sub-elements through which the flexible coupon 400 is heated in stages. The temperature control unit 600 can collect temperature data of the flexible sampling tube 400, and can adjust the heating power of the heating unit 700 by using the temperature data. Therefore, after the temperature control component 600 sets the heating target temperature of the flexible sampling tube 400, the closed-loop temperature control of the flexible heating tube can be realized, so that the temperature of the flexible sampling tube 400 is always kept in the allowable temperature range.

An assembly box according to an embodiment of the present invention will be described with reference to fig. 1 to 4.

The support body 200 is arranged at the middle position in the box body 100, a second storage space 210 is formed between the support body 200 and the box body 100, the second storage space 210 has enough depth and can be used for storing the coiled flexible sampling tube 400, and particularly when the flexible sampling tube 400 is long or a plurality of flexible sampling tubes 400 are arranged, the depth of the second storage space 210 can effectively ensure the storage and fixing effects. In addition, the heating unit 700 and the temperature control unit 600 may be placed in the second storage space 210 after the placement of the flexible sampling tube 400 is completed.

The top of support body 200 is provided with recess 220, can be used for placing flue gas analyzer in the recess 220, and flue gas analyzer can carry out real-time analysis to the flue gas when sampling device carries out the flue gas sample. A certain storage gap 230 is reserved between the top of the supporting body 200 and the inside of the top of the box 100, and the height of this storage gap 230 needs to be larger than the outer diameter of the single supporting sub-tube 310 to ensure that the supporting sub-tube 310 can be placed between the supporting body 200 and the top of the box 100 after disassembly. It should be noted that the length and width of the box 100 need to be able to accommodate the length of the support sub-tubes 310, and in general, to reduce the volume of the box 100, the support sub-tubes 310 may be placed diagonally in the box 100, and not vertically or parallel to the edges.

The detachable rotating device enables coiling of the flexible sampling tube 400. The detachable rotating means itself has a detachable capability and can be placed in the first storage space 110 at the top of the case 100 after being detached. In addition, in practical engineering, if the size or weight of the assembly box is large, universal wheels are arranged at the bottom of the assembly box body 100 so as to facilitate movement, and the portability is further improved. Meanwhile, in order to ensure the convenience of carrying the assembly box (for example, when it is required to carry the assembly box to a vehicle), a plurality of handles are provided to the box body 100.

According to the assembly box provided by the embodiment of the invention, the standard coiling of the flexible sampling tube 400 can be realized through the detachable rotating device, and meanwhile, the manpower and material resources required in the coiling process can be reduced; the detachable rotating device adopts a detachable structure, so that the detachable rotating device is convenient to store through the first storage space 110 after being detached; the coiled flexible sampling tube 400 can be stored through the second storage space 210; the support sub-tubes 310 may be stored through the storage gap 230.

In some embodiments of the present invention, the heating part 700 is a heat trace band disposed on the surface of the flexible sampling tube 400. The heat tracing band is flat in shape and has certain flexibility, and can be better attached to the surface of the flexible sampling tube 400, and the heat tracing band can heat each area of the flexible sampling tube 400 at the same time, so that the balance of heating effects is guaranteed, and meanwhile, the follow-up temperature control part 600 can conveniently carry out temperature acquisition and constant temperature control. In some embodiments of the present invention, the heat tracing band may use a graphene heating layer as a core heating component, or other heating sheets with certain toughness.

In some embodiments of the present invention, the temperature control member 600 comprises: a first temperature detection unit 610 and a controller 620. The first temperature detection unit 610 is used for acquiring first temperature data of the flexible sampling tube 400; the controller 620 is electrically connected to the first temperature detecting unit 610 and the heating member 700, respectively. First temperature detecting element 610 adopts temperature sensor can, because whole flexible sampling tube 400 adopts even heating again, so can directly use temperature sensor to detect the temperature data of flexible sampling tube 400 output port department can, controller 620 can compare with the heating target temperature that sets up in advance after receiving temperature data, realizes the closed loop control to the temperature for the temperature is stabilized near heating target temperature. In some embodiments of the present invention, the controller 620 may also be connected to a display and control device, such as: the combined structure of an OLED screen and a key or a liquid crystal touch screen realizes the adjustment of the heating target temperature through a display control device. In some embodiments of the present invention, the controller 620 may employ a single chip, a DSP, or an ARM. Specifically, the STM32 series may be used. In some embodiments of the present invention, the controller 620 needs to adjust the heat tracing temperature of the heat tracing band within a range of 0-200 ℃, and the thickness of the corresponding heat tracing band needs to be maintained at 2-5 mm and the width of the heat tracing band needs to be maintained at 10-20 mm, so as to ensure the heat tracing effect.

In some embodiments of the present invention, the first temperature sensing unit 610 does not directly contact the heating member 700 using a thermocouple. The first temperature detection unit 610 may directly employ a thermocouple, and only needs to ensure that the thermocouple does not directly contact with the heat tracing band, thereby avoiding an excessive temperature error of the acquisition.
