A fluid network is installed at the joint of the mounting plate and the fluid pipeline. This utility model solves the problem that when the existing measuring device measures the permeability of a natural gas reservoir, it needs to cooperate with a variety of precision instruments for on-site measurement, which requires a huge amount of manpower and material resources, is not conducive to cost saving of enterprises, and has low efficiency. However, in actual use, since the device is not provided with a moving mechanism, when the staff detects different complex environments, the device has the disadvantages of being inconvenient to move and carry.

[0003] Based on the disadvantage of the existing device being inconvenient to move, the utility model proposes a portable measuring device for the permeability of a tight natural gas reservoir. Content of the Utility Model

The central shaft is fixedly connected to the hollow part of the bottom plate. The seesaw is rotatably connected to the central shaft. One end of the seesaw is connected with a fixed rod, and the fixed rod is located at the bottom of the detection instrument. The other end of the seesaw is limited and fixed by a pressing rod that slidably penetrates through the bottom plate. A return spring is connected between the pressing rod and the bottom plate. The inner side of the pressing rod is set as a wedge shape, and the inclined surface of the wedge faces upward.

[0006] Preferably, it further includes a handle, and the handle is fixedly connected to the end of the bottom plate.

[0007] Preferably, it further includes a swing rod and a movable pull rod. The swing rod is rotatably connected to the handle, and a telescopic movable pull rod is arranged at the end of the swing rod.

[0008] Preferably, it further includes a buckle. The buckle is fixedly connected to the inner side of the handle, and the swing rod can be fixed in the buckle by a snap-fitting method.

[0009] Preferably, it further includes a buffer pad, and the buffer pad is arranged at the bottom of the bottom plate.

[0010] Preferably, it further includes a toolbox and an operating table, and both the toolbox and the operating table are arranged on the bottom plate.

[0011] Preferably, it further includes an anti-slip pad, and the anti-slip pad is arranged on the rocker.

[0012] The beneficial effect of the present utility model is that the device is set in the form of a mobile trolley combining universal moving wheels and a bottom plate, which improves the mobility of the device. In addition, a rocker and an extrusion rod for fixing it are provided, enabling the staff to conveniently take out and place the detection instrument, and improving the work convenience of the staff during the detection of the permeability of natural gas reservoirs.

Detailed Embodiment

[0017] The following is only the preferred embodiment of the present utility model, and does not limit the protection scope of the present utility model accordingly.

[0018] Embodiment: A portable device for measuring the permeability of tight natural gas reservoirs, as Figures 1-3As shown in the figure, it includes a detection instrument 1, a bottom plate 2, universal moving wheels 201, a fixed rod 3, a seesaw 4, a central axis 5, a pressing rod 6 and a return spring 7. The detection instrument 1 is placed on the bottom plate 2. The bottom of the bottom plate 2 is provided with universal moving wheels 201. In this embodiment, the universal moving wheels 201 are configured with a self-locking function. One side of the bottom plate 2 is in a hollow shape. The central axis 5 is fixedly connected to the hollow part of the bottom plate 2. The seesaw 4 is rotatably connected to the central axis 5. One end of the seesaw 4 is connected to a fixed rod 3. The fixed rod 3 is located at the bottom of the detection instrument 1. The other end of the seesaw 4 is limited and fixed by a pressing rod 6 that slides through the bottom plate 2. A return spring 7 is connected between the pressing rod 6 and the bottom plate 2. The inner side of the pressing rod 6 is set in a wedge shape, and the inclined surface of the wedge faces upward. That is, when the staff needs to take out the detection instrument 1, the pressing rod 6 can be pulled outwards, so that the wedge at the end of the pressing rod 6 disengages from the seesaw 4, and then the end of the seesaw 4 away from the detection instrument 1 is stepped on. Due to the lever principle, the other end of the pry bar will lift the detection instrument 1 upwards, facilitating the staff to take out the detection instrument 1. When the detection instrument 1 needs to be placed, the detection instrument 1 is moved downwards and pressed against the end of the seesaw 4, so that the seesaw 4 rotates back to its original position, and then the pressing rod 6 is used to fix the seesaw 4 in a clamping manner, so as to fix the detection instrument 1.

[0019] As Figure 1 and Figure 3 shown in the figure, it also includes a handle 8. Handles 8 are fixedly connected to both ends of the bottom plate 2. A swing rod 9 is rotatably connected to the handle 8. An extendable movable pull rod 10 is provided at the end of the swing rod 9. By rotating the swing rod 9, the staff can then pull the device through the movable pull rod 10. A buckle 11 is fixedly connected to the inner side of the handle 8. The swing rod 9 can be fixed in the buckle 11 by a clamping method to achieve the effect of instant storage.

[0020] As Figure 1 shown in the figure, it also includes a buffer pad 12. The buffer pad 12 is arranged at the bottom of the bottom plate 2. When the device passes through a rough road surface, if it encounters a bump, it is easy to damage the bottom plate 2, and then cause oscillation to the detection instrument 1, posing a risk of damage. Therefore, the buffer pad 12 is provided to prevent the rough road surface, preventing the bottom plate 2 from contacting the road surface protrusions, so as to achieve the protection effect on the detection instrument 1.

[0021] As Figure 1 shown in the figure, it also includes a toolbox 13 and an operating table 14. The toolbox 13 and the operating table 14 are both arranged on the bottom plate 2. Specifically, the toolbox 13 is fixedly connected to the right side of the bottom plate 2, while the operating table 14 is fixedly connected to the left side of the bottom plate 2. The toolbox 13 is used to place various detection devices, and the operating table 14 provides a place for the staff to write.

[0022] As Figure 1As shown, it further includes an anti-slip pad 15 which is arranged on the rocker 4. When the staff steps on the rocker 4, the anti-slip pad 15 effectively increases the friction coefficient between the staff's feet and the rocker 4, preventing the staff from slipping.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
