[0001] This utility model belongs to the field of natural gas technology, specifically relating to a natural gas flow monitoring device. Background Technology

[0002] Natural gas flow monitoring equipment is a key device used to measure, record, and analyze parameters such as natural gas flow, pressure, and temperature. It is widely used in fields such as gas transmission and distribution, industrial gas use, and energy metering. Most natural gas flow monitoring equipment requires the use of battery structures.

[0003] According to the patent announcement number CN222166216U for a natural gas flow monitoring device, this patent is known prior art. Although the patent has the advantage of quick battery replacement, the technical solution of this patent still has the following defects in actual use: In this patent, because the cover opens upwards, the power connector pops out from inside the natural gas flow monitoring device. Although this facilitates battery replacement, the large area of ​​the cover, the complex structure and the large opening method result in poor sealing of the natural gas flow monitoring device. When the natural gas flow monitoring device is installed in a relatively humid environment, moisture enters its interior, causing the metal conductive parts in the power connector to easily corrode, resulting in poor battery contact and seriously reducing the service life of the natural gas flow monitoring device. Utility Model Content

[0004] The purpose of this invention is to provide a natural gas flow monitoring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a natural gas flow monitoring device, comprising a natural gas pipeline and a connecting clamp installed on the outside of the natural gas pipeline, a monitor being disposed above the connecting clamp, the monitor being used to monitor the natural gas flow inside the natural gas pipeline, a positioning frame being fixedly installed on one outer wall of the monitor, a battery compartment being disposed at the bottom inside the monitor, a battery box being slidably disposed inside the battery compartment, a sealing component being disposed inside the positioning frame and sealingly contacting one end of the battery box, and a compression mechanism being inserted into the inside of the positioning frame from top to bottom.

[0006] In a preferred embodiment, the connecting clamp is a split structure, and the connecting clamp is connected and fixed by bolts.

[0007] In a preferred embodiment, the battery compartment has an open-end structure, and springs distributed vertically are provided inside one side of the battery compartment.

[0008] In a preferred embodiment, the positioning frame has slides on both sides of its front, guide blocks at the four corners of its interior, a passage at the top, and an insertion port on its front.

[0009] In a preferred embodiment, the battery box is inserted into the battery compartment from inside the positioning frame. The battery box contains batteries arranged vertically. The front of the battery box has several limiting pieces made of elastic material. The back of the battery box has a back hole, and conductive seats are fixedly installed on both sides of the back of the battery box.

[0010] In a preferred embodiment, the extrusion mechanism includes a pressure plate inserted into the positioning frame. The pressure plate has a notch at its outer corner. A rotating sleeve is provided at the center of one side of the pressure plate. A screw is rotatably connected inside the rotating sleeve. A sliding frame is sleeved on the outside of the screw. Both ends of the sliding frame are provided with lugs that slide vertically and vertically with the positioning frame. A rotating handle is fixedly installed at the end of the screw.

[0011] In a preferred embodiment, the sealing assembly includes a liner inserted into the socket, a folding plate fixedly disposed on the side of the liner, a core plate with an area smaller than the liner fixedly installed on one outer wall of the liner, and an inflatable rubber ring bonded to the outer wall of the liner disposed on the outside of the core plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This natural gas flow monitoring device, through the battery compartment set inside the monitor, allows the battery box to pass directly through the inside of the positioning frame and be installed inside the battery compartment. The opening at the positioning frame is small, and the sealing components and compression mechanism are used to seal the opening inside the positioning frame, which provides the overall airtightness of the monitor and is more suitable for use in humid environments, providing moisture-proof and rust-resistant capabilities. This natural gas flow monitoring device uses a liner of a sealing component inserted into the socket of a positioning frame. The liner can move left and right inside the socket, creating a gap.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1 This utility model provides a natural gas flow monitoring device, including a natural gas pipeline 1 and a connecting clamp 2 installed on the outside of the natural gas pipeline 1. A monitor 3 is provided above the connecting clamp 2. The monitor 3 is used to monitor the natural gas flow inside the natural gas pipeline 1. The connecting clamp 2 is a split structure and is connected and fixed by bolts.

[0018] In this embodiment, the monitor 3 is connected to the natural gas pipeline 1, allowing the natural gas inside the natural gas pipeline 1 to enter the monitor 3, thereby enabling the monitoring of the natural gas flow. The monitor 3 is fixedly installed outside the natural gas pipeline 1 by the connecting clamp 2.

[0019] Please see Figure 1 and Figure 3A positioning frame 4 is fixedly installed on one outer wall of the monitor 3. Slide rails 41 are provided on both sides of the front of the positioning frame 4. Guide blocks 42 are provided at the four corners inside the positioning frame 4. A passage 43 is provided on the top of the positioning frame 4. The design of the passage 43 can prevent obstruction when the rotating sleeve 63 and the screw 65 are taken out. The structure is reasonable. An insertion port 44 is provided on the front side of the positioning frame 4. The width of the insertion port 44 is greater than the sum of the thicknesses of the liner plate 71 and the core plate 73, so that the sealing component 7 can be smoothly inserted and move left and right inside it.

[0020] In this embodiment, the design of the slide rail 41 allows the sliding frame 64 to be installed inside it from top to bottom, which facilitates the assembly and disassembly of the sliding frame 64. The designed guide block 42 enables the pressure plate 61 to move stably in a straight horizontal direction when the extrusion mechanism 6 moves, ensuring that the pressure plate 61 applies stable and uniform pressure to the liner plate 71.

[0021] Please see Figure 2 , Figure 4 and Figure 5 The monitor 3 has a battery compartment 31 located at its lower interior. The battery compartment 31 is open at one end. Springs 32 are arranged vertically on one side of the battery compartment 31. A battery box 5 is slidably installed inside the battery compartment 31. The battery box 5 is inserted into the battery compartment 31 from the inside of the positioning frame 4. The battery box 5 contains batteries 51 arranged vertically. Several limiting pieces 52 made of elastic material are provided on the front of the battery box 5. When installing the battery 51, the battery 51 is squeezed inside the battery box 5 by force, so that the battery 51 passes through the limiting pieces 52 and enters its interior, thus achieving stable installation of the battery 51 inside the battery box 5. The back of the battery box 5 has a back hole 53, and conductive seats 54 are fixedly installed on both sides of the back of the battery box 5. After the battery box 5 is fully inserted into the battery compartment 31, the conductive seats 54 on the back of the battery box 5 contact the conductive seats 54 inside the monitor 3, thereby realizing the power transmission of the battery 51.

[0022] In this embodiment, the spring 32 allows the battery box 5 to be pushed out of the battery compartment 31 by a certain distance after the squeezing mechanism 6 and sealing component 7 are removed when the operator takes out the battery box 5, making it easier for people to pull the battery box 5 out of the battery compartment 31.

[0023] Please see Figure 3 and Figure 6The positioning frame 4 is equipped with a sealing component 7 that is in sealing contact with one end of the battery box 5. The sealing component 7 includes a liner 71 inserted into the socket 44. A folding plate 72 is fixedly provided on the side of the liner 71. A core plate 73 with an area smaller than the liner 71 is fixedly installed on one outer wall of the liner 71. An inflatable rubber ring 74 is provided on the outside of the core plate 73 and is bonded to the outer wall of the liner 71. The inflatable rubber ring 74 is filled with gas and sealed. After the pressure plate 61 squeezes the liner 71, it can compress the outside of the inflatable rubber ring 74, causing it to deform and providing a seal after the battery box 5 is installed.

[0024] In this embodiment, the sealing component 7 is inserted into the inside of the socket 44, and then the sealing component 7 is moved to the right by the squeezing mechanism 6, thereby achieving a better sealing effect.

[0025] Please see Figure 3 An extrusion mechanism 6 is inserted into the positioning frame 4 from top to bottom. The extrusion mechanism 6 is used to extrude the sealing assembly 7 toward the battery compartment 31. The extrusion mechanism 6 includes a pressure plate 61 inserted into the positioning frame 4. A notch 62 is provided at the outer corner of the pressure plate 61. A rotating sleeve 63 is provided at the center of one side of the pressure plate 61. The design of the rotating sleeve 63 allows the pressure plate 61 to move horizontally and linearly when the screw 65 rotates. The pressure plate 61 extrudes the liner 71, causing the liner 71 to shift. The screw 65 is rotatably connected inside the rotating sleeve 63. A sliding frame 64 is sleeved on the outside of the screw 65. Both ends of the sliding frame 64 are provided with lugs that slide vertically and vertically with the positioning frame 4. Due to the presence of the lugs, the lugs slide vertically and vertically along the positioning frame 4, so that the sliding frame 64 will not rotate when the screw 65 is rotated. A rotating handle 66 is fixedly installed at the end of the screw 65. The operator holds the rotating handle 66 to facilitate the rotation of the screw 65.

[0026] In this embodiment, the extrusion mechanism 6 is inserted into the positioning frame 4 from top to bottom, and the extrusion mechanism 6 is moved to the right to extrude the sealing component 7, thereby ensuring the stability of the installation of the sealing component 7 and realizing the sealing connection of the sealing component 7 to one end of the battery compartment 31.

[0027] The working principle and usage process of this utility model are as follows: When replacing battery 51, the operator first contacts the pressing mechanism 6, causing the sealing component 7 to move to the left. The operator holds the rotating handle 66 to rotate the screw 65. Since the sliding frame 64 is engaged inside the slide rail 41 of the positioning frame 4, it will not rotate. As the screw 65 rotates, the screw 65 itself moves to the left, thereby using the rotating sleeve 63 to drive the pressure plate 61 to move to the left. The pressure plate 61 moves on the guide block 42 through the notch 62. When the pressure plate 61 moves to the left and aligns with the through port 43 above the positioning frame 4, the operator can then press the entire pressing mechanism 6. Move the battery out along the positioning frame 4. Since the squeezing mechanism 6 is removed, there is no support on the side of the liner 71. The liner 71, core plate 73 and inflatable rubber ring 74 move to the left at the same time. The core plate 73 and inflatable rubber ring 74 are separated from the opening of the battery compartment 31. The operator pulls the sealing component 7 forward from the inside of the insertion port 44. Finally, the battery box 5 is pulled out from the inside of the battery compartment 31. The battery box 5 can be completely removed through the positioning frame 4. The operator can replace the battery 51. A rod-shaped tool can be inserted from the back hole 53 of the battery box 5 to allow the battery 51 to be removed from the front side of the battery box 5, passing over the limiting piece 52. When replacing and installing battery 51, the operator installs battery 51 inside battery box 5, inserts battery box 5 into battery compartment 31 from inside positioning frame 4, inserts sealing component 7 into socket 44, and then installs pressing mechanism 6 inside positioning frame 4. The pressing mechanism 6 is used to move sealing component 7 to the right, ensuring the sealing and reliability of battery box 5 installed inside battery compartment 31.

[0028] In the above scheme, it should be noted that: the monitor 3 in this application is an existing natural gas detection product, and the specific structure of the monitor 3, the electrical connection method (circuit layout) with the battery 51, and the monitoring principle of the monitor 3 itself are all existing publicly disclosed technical means. The model of the monitor 3 is not limited here, and an appropriate existing model can be selected according to actual needs. It will not be described in detail here.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
