Abstract
Description
Technical Field
[0001] This invention relates to the technical field of gas pressure detection in coalbed methane extraction, specifically to a gas pressure measuring device for deep coalbed methane extraction. Background Technology
[0002] Coalbed methane, commonly known as "gas," is a gaseous resource associated with and coexisting with coal. It refers to hydrocarbon gases stored in coal seams, primarily composed of methane, and is classified as unconventional natural gas. Coalbed methane consists mainly of hydrocarbon gases adsorbed on the surface of coal matrix particles, with some remaining free in coal pores or dissolved in coal seam water. It is a associated mineral resource of coal and has emerged as a clean, high-quality energy source and chemical raw material internationally in the last one or two decades. Coalbed methane extraction involves deep-level gas pressure testing, typically using relevant pressure gauges.
[0003] A search revealed Chinese Patent Publication No. CN113503146A, published on October 15, 2021, which discloses a deep coalbed methane extraction pressure measuring device, including a mounting platform; a winding structure on the top side of the mounting platform; an extension structure on the winding structure; a connecting structure on the inner side of the extension structure; and a support structure on the bottom side of the mounting platform, with a storage structure on the support structure. The winding structure winds and releases the cable while ensuring its release. The extension structure extends deep into the mine bottom for pressure measurement, while also protecting the cable. The connecting structure facilitates smoother sliding between the first and second support shells and the cable, providing more comprehensive cable protection. The support structure supports the structure, facilitating cable tensioning and measurement. The storage structure allows for convenient storage of the first and second support rods, simplifying transportation.
[0004] However, it still has the following drawbacks in practical use:
[0005] Existing pressure measuring devices are typically placed directly in the environment where pressure needs to be measured, and the pressure value displayed on the device's screen is viewed after a period of time. However, when measuring the pressure in deep coalbed methane, it is impossible to place the device in a fixed position, making it difficult to measure the pressure in coalbed methane at different depths.
[0006] Therefore, existing deep coalbed methane extraction gas pressure measurement devices cannot meet the needs of actual use, so there is an urgent need for improved technologies to solve the above problems. Summary of the Invention
[0007] The purpose of this invention is to provide a gas pressure measuring device for deep coalbed methane extraction. By setting up a connecting component, it solves the problem that existing gas pressure measuring devices, when in use, are usually placed directly in the environment where the gas pressure needs to be measured, and the gas pressure value displayed on the device screen is viewed directly after a period of time. When measuring the gas pressure in deep coalbed methane, it is impossible to place and fix the device manually, which makes it difficult to measure the gas pressure in coalbed methane at different depths.

[0014] As a preferred embodiment of the present invention, a detection component is fixedly connected to the middle of the other end surface of the body, and the detection component includes a pressure detection head and a distance measuring head. The distance measuring head is electrically connected to the middle of the upper surface of the pressure detection head; the distance measuring head facilitates the measurement of depth.
[0015] As a preferred embodiment of the present invention, a pair of first screw holes are provided on one end surface of both sides of the body, and a first rear cover plate is fastened to the upper part of the back of the body. The four corners of the outer surface of the first rear cover plate are provided with first slots, and first screws are inserted into the first slots. The first screws facilitate the structural connection or disassembly of the first rear cover plate and the body.
[0016] As a preferred embodiment of the present invention, a second rear cover is fastened to the lower part of the back of the body, and a second slot is provided at the four corners of the outer surface of the second rear cover. A heat dissipation hole is provided in the middle of the outer surface of the second rear cover, and a second screw is inserted into the second slot.

[0018] The beneficial effects of this invention are:
[0019] This invention, by setting up a connecting component, has the advantage of facilitating the detection of gas pressure in coalbed methane at different depths. It solves the problem that existing gas pressure measuring devices, when in use, are usually placed directly in the environment where the gas pressure needs to be detected, and the gas pressure value displayed on the device's screen is viewed directly after a period of time. When detecting the gas pressure in deep coalbed methane, it is impossible to place and fix the device manually, which makes it difficult to detect the gas pressure in coalbed methane at different depths.
[0020] This invention, by incorporating a Bluetooth module, has the advantage of providing immediate information on the gas pressure values of coalbed methane layers at different depths. This solves the problem that existing deep coalbed methane extraction gas pressure measurement devices typically require a traction device to pull the device from the deep coalbed methane layer to the surface to obtain pressure values, thus limiting their use due to the inability to provide timely information on gas pressure values at different depths.
