[0023] 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.

[0024] like Figure 1 As shown:

[0025] An environmental monitoring gas chromatograph includes a gas chromatograph body 1.

[0026] In this implementation plan: To address the technical problems existing in the prior art, such as the aforementioned background art disclosure that "when the current gas chromatograph is being repaired and parts are being replaced, the housing obstructs the movement range of maintenance personnel within the housing, making it difficult to better access various components, such as detectors, injectors, and separation columns, thereby increasing the difficulty of maintenance and diagnostic time, and reducing maintenance efficiency," this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, auxiliary component 2 has been added to this application. All electrical equipment involved in this product is powered by an external power source.

[0027] Furthermore:

[0028] like Figures 1-4 As shown:

[0029] An auxiliary component 2 is installed inside the main body 1 of the gas chromatograph. The auxiliary component 2 includes a housing plate 201 disposed on the rear side of the main body 1 of the gas chromatograph, a base plate 207 disposed below the inner cavity of the main body 1 of the gas chromatograph, and slide rails 214 symmetrically arranged between the base plate 207 and the main body 1 of the gas chromatograph.

[0030] An adjusting screw 209 is rotatably connected to the inside of the base plate 207 via a bearing. A connecting plate 210 is threaded onto the surface of the adjusting screw 209. A rectangular groove is provided on one side of the base plate 207 to facilitate the up-and-down movement of the connecting plate 210. A symmetrically arranged pin 211 is fixed on the lower surface of the connecting plate 210. A fixing block 208 corresponding to the two sets of pins 211 is fixed at the bottom of the inner cavity of the gas chromatograph body 1.

[0031] The top of the fixing block 208 is provided with a slot that matches the pin 211. Two sets of pins 211 are inserted into the slots provided in the fixing block 208 to lock the position between the base plate 207 and the gas chromatograph body 1.

[0032] The internal structure of the gas chromatograph body 1 is all mounted on the surface of the base plate 207;

[0033] The surface of the base plate 207 has a through hole for the pin 211 to move through, and the pin 211 and the base plate 207 are slidably connected through this through hole.

[0034] In this implementation plan: When it is necessary to repair or replace the internal structure of the main body 1 of the gas chromatograph for environmental monitoring, the shell plate 201 is first disassembled.

[0035] Then, rotating the adjusting screw 209 causes the connecting plate 210 to move upwards due to its threaded connection with the connecting screw 209. This, in turn, causes the pin 211 to move upwards, disengaging it from the slot in the fixing block 208 and releasing the position lock of the base plate 207. The base plate 207 is then pulled, sliding within the gas chromatograph body 1 via the slide rail 214. The slide rail 214 ensures greater stability during the movement of the base plate 207. The base plate 207 is then removed from the gas chromatograph body 1, causing the internal structure of the gas chromatograph body 1 to move synchronously. This operation allows technicians easier access to components such as detectors, injectors, and separation columns for repair, replacement, or cleaning and upgrades. This reduces maintenance difficulty, improves efficiency, and makes fault diagnosis more intuitive and accurate. Technicians can quickly locate the problem, reducing diagnostic time, accelerating the repair process, and further improving the effectiveness of the device.

[0036] It should be noted that when the gas chromatograph body 1 has a display screen, the internal components of the gas chromatograph body 1 are connected by long wires, so as not to affect the extraction effect of the base plate 207 on the gas chromatograph body 1.

[0037] Furthermore;

[0038] In an optional embodiment, a strip plate 212 is welded to the surface of the pin 211, and a caster wheel 213 is fixedly mounted on the lower surface of the strip plate 212 away from the pin 211 by bolts.

[0039] In this embodiment: when the base plate 207 moves the pin 211, strip plate 212 and caster 213 out of the gas chromatograph body 1, the adjusting screw 209 is rotated, which in turn moves the connecting plate 210 downward. The connecting plate 210 moves the pin 211, strip plate 212 and caster 213 downward synchronously until the caster 213 contacts the ground. Thus, when most of the base plate 207 is moved out of the gas chromatograph body 1, the caster 213 and strip plate 212 can support the moved part of the base plate 207, thereby avoiding damage caused by the connection between the base plate 207 and the slide rail 214, and further improving the use effect of the device.

[0040] Furthermore;

[0041] In an optional embodiment, elastic buckles 202 arranged symmetrically are fixedly installed on both sides of the gas chromatograph body 1 by screws, and locking ears 203 that engage with the elastic buckles 202 are fixedly installed on both sides of the housing plate 201 by connecting blocks. The elastic buckles 202 are fastened to the locking ears 203 to lock the housing plate 201.

[0042] The upper and lower ends of the gas chromatograph body 1 near the housing plate 201 are respectively fixed with a limit cover 206 and a base plate 205 by bolts. The housing plate 201 is inserted between the base plate 205 and the limit cover 206. The position of the housing plate 201 is limited by the base plate 205 and the limit cover 206.

[0043] In this embodiment: by prying open the elastic buckle 202, the fastening of the locking lug 203 is released, and then the housing plate 201 is removed from the gas chromatograph body 1. The setting of the elastic buckle 202 and the locking lug 203 facilitates the disassembly of the housing plate 201. The bolt fixing of the housing plate 201 improves the disassembly and assembly effect.

[0044] The housing plate 201 can be removed from the base buckle plate 205 and the limiting cover 206. The base buckle plate 205 and the limiting cover 206 can limit the orientation of the housing plate 201, thereby improving the stability of the installation of the housing plate 201.

[0045] Furthermore;

[0046] In an optional embodiment, a sealing gasket 204 is fixedly installed on the inner sidewall of the housing plate 201, which is used to increase the sealing between the housing plate 201 and the gas chromatograph body 1.

[0047] In this embodiment, the sealing gasket 204 is used to increase the sealing performance between the housing plate 201 and the gas chromatograph body 1, thereby preventing dust from entering the interior of the gas chromatograph body 1 and affecting the precision components, and further improving the performance of the device.

[0048] The working principle and usage process of this utility model are as follows: When it is necessary to repair or replace parts of the internal structure of the gas chromatograph body 1, the elastic buckle 202 is first pried open to release the locking lug 203. Then, the housing plate 201 is removed from the gas chromatograph body 1. The elastic buckle 202 and locking lug 203 facilitate the disassembly of the housing plate 201, which is easier than the bolt fixing of the housing plate 201, thus improving the disassembly and assembly efficiency. The housing plate 201 is then removed from the base buckle plate 205 and the limiting cover 206. The base buckle plate 205 and the limiting cover 206 can limit the orientation of the housing plate 201. This improves the stability of the housing plate 201 during installation. The sealing gasket 204 increases the sealing between the housing plate 201 and the gas chromatograph body 1, preventing dust from entering the interior of the gas chromatograph body 1 and affecting precision components, thus further improving the device's performance. Then, rotating the adjusting screw 209, which is threadedly connected to the connecting plate 210, causes the connecting plate 210 to move upwards. This, in turn, causes the pin 211 to move upwards, disengaging it from the slot in the fixing block 208, thereby releasing the position lock of the base plate 207. Finally, pulling the base plate 207... The base plate 207 slides within the gas chromatograph body 1 via slide rail 214. This slide rail design ensures greater stability during the movement of the base plate 207. The base plate 207 is then removed from the gas chromatograph body 1, causing the internal structures of the gas chromatograph body 1 to move synchronously. This operation allows technicians easier access to various components, such as detectors, injectors, and separation columns, for repair, replacement, or cleaning and upgrades. This reduces maintenance difficulty, improves maintenance efficiency, and makes fault diagnosis more intuitive and accurate. Technicians can quickly locate the problem, reducing diagnostic time, accelerating the repair process, and further improving... The device's performance is enhanced when the base plate 207 moves the pin 211, strip plate 212, and caster 213 out of the gas chromatograph body 1. Rotating the adjusting screw 209 then moves the connecting plate 210 downwards. The connecting plate 210 then moves the pin 211, strip plate 212, and caster 213 downwards synchronously until the caster 213 contacts the ground. Thus, when most of the base plate 207 is removed from the gas chromatograph body 1, the caster 213 and strip plate 212 provide support for the removed portion of the base plate 207, preventing damage caused by the connection between the base plate 207 and the slide rail 214, thereby further improving the device's performance.

[0049] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
