[0003] Existing equipment generally relies on multi-stage separation technology, which results in large and heavy equipment. At the same time, traditional equipment is mostly fixed or semi-fixed, relying on ground bases or heavy supports for fixation. When relocating, it needs to be disassembled and reassembled, which is time-consuming and labor-intensive, making it difficult to adapt to the needs of mobile exploration and seriously restricting exploration efficiency.

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a mobile gas sampling device to solve the technical problem that the current devices are bulky and heavy, making them difficult to adapt to the needs of mobile exploration.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A mobile gas sampling device includes a walking chamber with a door, a separation tank mounted on the top of the walking chamber via a bracket, a sampling valve installed at the inlet on one side of the separation tank, a gas sampling valve fixed at the outlet on the other side of the separation tank, a waste liquid valve installed at the drain end at the bottom of the separation tank, a baffle plate one welded inside the separation tank and near the sampling valve, and a baffle plate two welded inside the separation tank and near the gas sampling valve.

[0008] The walking compartment is equipped with a bracket, and a waste liquid tank is detachably installed in the mounting cavity of the bracket, and a feed pipe is installed at the feed end of the top of the waste liquid tank.

[0009] A positioning component is installed inside the traveling chamber. The inlet end of the positioning component is installed at the outlet end of the waste liquid valve, and the outlet end of the positioning component is located directly above the feed pipe of the waste liquid tank.

[0010] As an improved technical solution, the bracket includes a tray, and vertical columns are welded to the four corners of the bottom of the tray. Column grooves for the vertical columns to pass through are opened on both sides of the bottom of the walking compartment. A walking wheel is installed at the end of the vertical column away from the tray.

[0011] As an improved technical solution, side baffles are fixed on both sides of the top of the pallet, and arc-shaped limiting frames are fixed at both ends of the opposite surfaces of the two side baffles. Arc-shaped edges are provided on the opposite surfaces of the two arc-shaped limiting frames on the same side. A limiting tank cavity for limiting the position of the waste liquid tank is formed between the side baffles on both sides and the arc-shaped limiting frames on both sides.

[0012] As an improved technical solution, the positioning component includes two electric telescopic rods installed on both sides inside the walking chamber, and a metal hose installed at the outlet end of the waste liquid valve. A lifting plate is fixedly connected between the movable ends of the two electric telescopic rods. A rigid connecting pipe is inserted into the middle of the top of the lifting plate, and the inlet end of the rigid connecting pipe is connected to the outlet end of the metal hose.

[0013] As an improved technical solution, the rigid connecting pipe and the feed connecting pipe on the waste liquid tank are arranged coaxially, and the diameter of the rigid connecting pipe is the same as the diameter of the feed connecting pipe.

[0014] As an improved technical solution, a sealing gasket is bonded to the end of the rigid connecting pipe away from the metal flexible tube, and the sealing gasket is one centimeter thick.

[0015] As an improved technical solution, positioning holes are provided at both ends of the top of the side baffle, and positioning rods are installed at the four corners of the bottom of the lifting plate and directly above the positioning holes, and the positioning rods are engaged with the positioning holes.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the top of the pallet defines a tank cavity, which holds the waste liquid tank inside the defined tank cavity, making it easy to put the waste liquid tank on and take it off the pallet. At the same time, the waste liquid tank is lifted by the bracket and passes through the column groove into the interior of the traveling compartment. When storing or retrieving the traveling compartment from inside the traveling compartment, the bracket can be pushed to move and transport the waste liquid tank. This helps to reduce the intensity of assembling, disassembling and moving the waste liquid tank, and makes it easier to discharge the waste liquid inside the waste liquid tank.

[0018] 2. In this utility model, when the waste liquid tank is located inside the traveling chamber, the electric telescopic rod shortens and drives the lifting plate to move downward, pressing the rigid connecting pipe onto the top of the waste liquid tank's feed connecting pipe, thus achieving communication between the separation tank and the inside of the waste liquid tank. At this time, the positioning rod will also be inserted into the corresponding positioning hole. The four positioning rods are engaged with each other to fix the bracket inside the traveling chamber, which further prevents the waste liquid tank from shaking during liquid collection and improves the stability of the waste liquid tank's liquid collection.

[0019] 3. This utility model, through the design of a mobile gas sampling device, is portable, improves work efficiency, ensures operational safety, reduces environmental pollution, and brings great convenience and improvement to the sampling and subsequent processing of oil and gas wells.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0032] like Figures 1 to 5 As shown in the figure, this embodiment provides a mobile gas sampling device. This mobile gas sampling device includes a walking chamber 1 with a door. A pusher frame is welded to one side of the walking chamber 1, and a U-shaped frame is installed on the other side. Universal wheels are installed at the four corners of the bottom of the walking chamber 1. A separation tank 2 is installed on the top of the walking chamber 1 via a bracket. A sampling valve 6 is installed at the inlet on one side of the separation tank 2. A gas sampling valve 8 is fixed at the outlet on the other side of the separation tank 2. A waste liquid valve 7 is installed at the drain end at the bottom of the separation tank 2. A baffle 9 is welded to the inside of the separation tank 2 and to the side near the sampling valve 6. A baffle 10 is welded to the inside of the separation tank 2 and to the side near the gas sampling valve 8. After the sample enters the separation tank 2, it moves downwards under the obstruction of the baffle 9 and the gravitational potential energy of the sample. The installation of the baffle prevents gas and liquid from splashing, and avoids unseparated samples from directly entering the gas sampling valve 8 without complete separation when the pressure is too high, thus more effectively ensuring the purity of the gas sample.

[0033] The walking chamber 1 is equipped with a bracket 3. A waste liquid tank 4 is detachably installed in the mounting cavity of the bracket 3. A feed pipe is installed at the feed end of the top of the waste liquid tank 4. Lifting frames can be welded to both ends of the waste liquid tank 4. An ultrasonic liquid level sensor is installed inside the waste liquid tank 4. When the waste liquid in the waste liquid tank 4 reaches the alarm position, an alarm will be automatically triggered to remind the user to replace the waste liquid tank 4 in time to avoid waste liquid overflow and environmental pollution.

[0034] Positioning component 5 is installed inside the traveling chamber 1. The liquid inlet of positioning component 5 is installed at the liquid outlet of waste liquid valve 7, and the liquid outlet of positioning component 5 is located directly above the feed pipe of waste liquid tank 4.

[0035] like Figures 1 to 4 As shown in the figure, in this embodiment, the bracket 3 includes a support plate 31, and vertical columns 32 are welded to the four corners of the bottom of the support plate 31. The two sides of the bottom of the walking chamber 1 are provided with column grooves 11 for the vertical columns 32 to pass through. The end of the vertical column 32 away from the support plate 31 is equipped with a walking wheel 33. The waste liquid tank 4 is lifted by the bracket 3 and passes through the column grooves 11 to enter the interior of the walking chamber 1. When accessing the walking chamber 1 from the inside, the bracket 3 can be pushed to move to realize the transportation of the waste liquid tank 4, which helps to reduce the intensity of the assembly, disassembly and movement of the waste liquid tank 4, and makes it easier to discharge the waste liquid inside the waste liquid tank 4.

[0036] like Figure 3 As shown, in this embodiment, side baffles 35 are fixed on both sides of the top of the tray 31, and arc-shaped limiting frames 34 are fixed at both ends of the opposite surfaces of the two side baffles 35. The opposite surfaces of the two arc-shaped limiting frames 34 on the same side are provided with arc-shaped edges. A limiting cavity for limiting the waste liquid tank 4 is formed between the two side baffles 35 and the two arc-shaped limiting frames 34. The limiting cavity at the top of the tray 31 is formed, which holds the waste liquid tank 4 inside the limiting cavity, making it easy to put the waste liquid tank 4 on the tray 31. In addition, the limiting cavity for limiting the waste liquid tank 4 also prevents the waste liquid tank 4 from moving when placed on the tray 31, thus improving the stability of the waste liquid tank 4 when collecting liquid.

[0037] like Figure 4 As shown, in this embodiment, the positioning component 5 includes two electric telescopic rods 51 installed on both sides inside the walking chamber 1, and a metal hose 54 installed at the outlet end of the waste liquid valve 7. The top of the walking chamber 1 has a pipe hole for the metal hose 54 to pass through. A lifting plate 53 is fixedly connected between the movable ends of the two electric telescopic rods 51. A rigid connecting pipe 55 is inserted and installed in the middle of the top of the lifting plate 53, and the feed end of the rigid connecting pipe 55 is connected to the outlet end of the metal hose 54.

[0038] like Figures 1 to 4 As shown in the figure, in this embodiment, the rigid connecting pipe 55 and the feed connecting pipe on the waste liquid tank 4 are arranged in a coaxial state, and the diameter of the rigid connecting pipe 55 is the same as the diameter of the feed connecting pipe.

[0039] like Figure 4As shown, in this embodiment, a sealing gasket is attached to the end of the rigid connecting pipe 55 away from the metal flexible hose 54, and the thickness of the sealing gasket is one centimeter. The electric telescopic rod 51 shortens and drives the lifting plate 53 to move downward, pressing the rigid connecting pipe 55 onto the top of the feed connecting pipe of the waste liquid tank 4, thereby realizing the connection between the separation tank 2 and the waste liquid tank 4. The contact connection facilitates the quick connection and disassembly between the two, and the setting of the sealing gasket reduces the gap of the connection surface.

[0040] like Figures 3 to 4 As shown in the figure, in this embodiment, positioning holes 36 are provided at both ends of the top of the side baffle 35, and positioning rods 52 are installed at the four corners of the bottom of the lifting plate 53 and directly above the positioning holes 36. The positioning rods 52 are engaged with the positioning holes 36, and the positioning rods 52 are also inserted into the interior of the positioning holes 36. The engagement between the four positioning rods 52 and the four 56 fixes the bracket 3 inside the walking chamber 1, which further prevents the waste liquid tank 4 from shaking when collecting liquid and improves the stability of the waste liquid tank 4 during liquid collection.

[0041] When in use, when the waste liquid tank 4 is inside the traveling chamber 1, the electric telescopic rod 51 shortens and drives the lifting plate 53 to move downward, pressing the rigid connecting pipe 55 onto the top of the feed connecting pipe of the waste liquid tank 4, thereby achieving communication between the separation tank 2 and the inside of the waste liquid tank 4.

[0042] The unseparated sample enters the interior of the separation tank 2 through the injection valve 6. After entering the separation tank 2, the sample moves downward under the obstruction of the baffle 9 and the gravitational potential energy of the sample.

[0043] After the sample enters the separation tank 2, it undergoes gas-liquid separation under the influence of gravitational potential energy. The waste liquid flows downward through the waste liquid valve 7 and the metal hose 54 into the waste liquid tank 4. When the gas sample enters the separation tank 2 through the sampling valve 6, it is first emptied for 30 seconds, and then the newly separated gas replaces the original gas in the separation tank 2. Then, the gas sample bag is connected to the exhaust end of the gas sampling valve 8 for gas sampling.

[0044] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
