Description

Technical Field

[0001] This utility model belongs to the technical field of earthquake observation equipment, specifically relating to an anti-vibration fixing device for a gas collecting vessel in an earthquake fluid observation well. Background Technology

[0002] Seismic fluid observation wells are underground facilities used to monitor seismic activity. In these wells, gas pipelines are a crucial component connecting the well to the observation instruments. By observing and analyzing changes in the physical and chemical properties of underground fluids, precursory information about earthquakes can be obtained, providing a basis for earthquake prediction.

[0003] During seismic fluid observation, gas pressure fluctuations and flow rate changes can cause strong vibrations and impacts on gas pipelines. However, traditional rigid fixing methods cannot effectively absorb the vibration energy caused by these vibrations and impacts. Furthermore, since gas collectors are usually made of glass, vibrations in the gas pipeline can easily damage the gas collectors. In addition, the rigid connection between the gas collector and the gas pipeline can easily lead to loosening and breakage of the joints, resulting in gas leakage and affecting the accuracy and reliability of the observation data. Utility Model Content

[0004] To overcome the limitations of traditional rigid fixing methods in the prior art, which cannot effectively absorb vibration energy caused by gas pressure fluctuations and flow rate changes, and the fact that gas collectors are typically made of glass, making them susceptible to damage from gas pipeline vibrations, and that rigid connections between the gas collector and gas pipeline are prone to loosening and cracking, leading to gas leakage and affecting the accuracy and reliability of observation data, this invention provides a shock-resistant fixing device for gas collectors in seismic fluid observation wells. This device uses a first positioning hole with an annular rubber pad inside a test tube box, along with a double-layer support plate, to fix the gas collector. Simultaneously, a first and second fixing clamp are used to secure the gas pipeline, and the first and second rubber sleeves absorb the vibration energy from the gas pipeline. Furthermore, flexible hoses are used for connections between the gas collector and the gas pipeline, as well as between adjacent gas collectors, reducing the vibration energy transmitted to the gas collector and thus lowering the risk of damage due to vibration. This also reduces the possibility of loose connections, ensuring the accuracy and reliability of the observation data.

A second gas pipe connecting to the outside is arranged inside the first gas pipe. The first and second gas pipes of adjacent gas collecting vessels are connected by a hose.

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0020] This utility model discloses a shockproof fixing device for a gas collecting vessel in a seismic fluid observation well. The device mainly includes a base 1, a first fixing clamp 2, a first rubber sleeve 3, a pressure plate 4, a screw 5, a second fixing clamp 6, a second rubber sleeve 7, a hose 8, and a test tube box 9. Inside the test tube box 9, two horizontal support plates 901 are equidistantly arranged. Each support plate 901 has multiple first positioning holes 902 equidistantly opened for mounting the gas collecting vessel. Each first positioning hole 902 is fitted with a diameter... A ring-shaped rubber gasket 903, smaller than the outer diameter of the gas collecting vessel, is attached to a threaded sealing cap 701 at the top of the gas collecting vessel. A first gas pipe 702, communicating with the interior of the gas collecting vessel, is axially arranged on the sealing cap 701. A second gas pipe 703, connecting to the outside, is installed inside the first gas pipe 702. Adjacent gas collecting vessels are connected by a flexible hose 8. A through hole 904 is provided on the side wall of the test tube box 9 for installing a gas pipeline 11. One end of the gas pipeline 11 passes through the through hole 904 and connects to the second gas pipeline 703 via the flexible hose 8. The tube 703 is connected; the base 1 is installed on the side wall of the test tube box 9, and two positioning sleeves 101 are provided on the base 1. The inner wall of the positioning sleeve 101 is provided with internal threads. The first fixing clamp 2 and the second fixing clamp 6 are both provided with second positioning holes 201 and mounting grooves 202. The second positioning holes 201 and mounting grooves 202 are coaxial. The pressure plate 4 is installed on the top of the second fixing clamp 6. The pressure plate 4 is provided with a through hole coaxial with the second positioning hole 201 on the second fixing clamp 6. The bottom end of the screw 5 passes through the hole and the second positioning hole 201 and is connected to the positioning sleeve. 101 Threaded connection; The first rubber sleeve 3 is fitted on the outer wall of the positioning sleeve 101 and is located in the mounting groove 202 at the bottom of the first fixing clamp 2. One end of the first rubber sleeve 3 is pressed against the end face of the base 1, and the other end is pressed against the end face of the mounting groove 202; The second rubber sleeve 7 is fitted on the screw 5 and is located in the mounting groove 202 at the top of the second fixing clamp 6. One end of the second rubber sleeve 7 is pressed against the pressure plate 4, and the other end is pressed against the end face of the mounting groove 202; A semi-circular clamping groove 203 is provided on the contact surface of the first fixing clamp 2 and the second fixing clamp 6.

[0021] First, the gas collecting vessel is mounted on the first positioning hole 902 with the annular rubber pad 903 inside the test tube box 9. A flexible hose 8 is used to connect the first gas pipe 702 and the second gas pipe 703 between adjacent gas collecting vessels. Next, one end of the gas pipe 11 is inserted into the through hole 904 of the test tube box 9, and its end is connected to the first gas pipe 702 or the second gas pipe 703 on the gas collecting vessel via the flexible hose 8. The operator places the first rubber sleeve 3 on the outer wall of the positioning sleeve 101 and inserts it into the mounting groove 202 at the bottom of the first fixing clamp 2. Then, the second fixing clamp 6 is placed on the first fixing clamp 2, so that the gas pipe 11 is located in the clamping groove 203 of the first fixing clamp 2 and the second fixing clamp 6. Meanwhile, ensure that the second positioning hole 201 on the second fixing clamp 6 is aligned with the second positioning hole 201 on the first fixing clamp 2. Then, put the second rubber sleeve 7 on the screw 5, and pass the bottom end of the screw 5 through the through hole of the pressure plate 4, the second positioning hole 201 of the first fixing clamp 2 and the second fixing clamp 6 in sequence, and screw it into the positioning sleeve 101. Then, the operator gradually tightens the screw 5, so that the pressure plate 4 presses down to tighten the second rubber sleeve 7, thereby firmly fixing the second fixing clamp 6 on the first fixing clamp 2, ensuring that the gas pipeline 11 is firmly clamped. When the gas pressure or flow rate changes and causes the gas pipeline 11 to vibrate, the first rubber sleeve 3 and the second rubber sleeve 7 will be compressed, thereby absorbing the energy generated by the vibration of the gas pipeline 11, thereby reducing vibration and impact. The clamping action of the first fixing clamp 2 and the second fixing clamp 6, the shock absorption action of the first rubber sleeve 3 and the second rubber sleeve 7, and the connection with the hose 8 effectively reduce the vibration caused by changes in gas pressure or flow rate, further reducing the vibration energy transmitted to the gas collector, thereby reducing the risk of damage to the gas collector due to vibration, and reducing the possibility of loose joints, ensuring the accuracy and reliability of the observation data.

[0022] The inner wall of the clamping groove 203 is provided with multiple sets of arc-shaped mounting grooves 2031 equidistantly along the axial direction. The arc-shaped mounting grooves 2031 are embedded with semi-arc-shaped anti-slip washers 10. The anti-slip washers 8 can play a buffering role, reduce the direct friction between the gas pipeline 11 and the clamping groove 203, thereby reducing the degree of wear and extending the service life of the gas pipeline 11.

[0023] The test tube box 9 is provided with a lid 12 at the top and locks 13 are installed on both sides of the test tube box 9. The lid 12 is fastened to the test tube box 9 by the locks 13. The lid 12 can prevent dust and debris from entering the test tube box 9 and keep the inside clean. It can also prevent the gas collecting vessel from being hit by external objects.

[0024] The anti-slip washer 10 is made of rubber; the anti-slip washer 10 can absorb some of the vibration energy, further enhancing the shock absorption effect of the gas pipeline.

[0025] The test tube box 9 is made of acrylic material; acrylic material has good transparency, which makes it easy for users to clearly observe the gas collecting vessel and other components inside.

[0026] Work process:

[0027] First, the gas collecting vessel is mounted on the first positioning hole 902 with the annular rubber pad 903 inside the test tube box 9. A flexible hose 8 is used to connect the first gas pipe 702 and the second gas pipe 703 between adjacent gas collecting vessels. Next, one end of the gas pipe 11 is inserted into the through hole 904 of the test tube box 9, and its end is connected to the first gas pipe 702 or the second gas pipe 703 on the gas collecting vessel via the flexible hose 8. The operator places the first rubber sleeve 3 on the outer wall of the positioning sleeve 101 and inserts it into the mounting groove 202 at the bottom of the first fixing clamp 2. Then, the second fixing clamp 6 is placed on the first fixing clamp 2, so that the gas pipe 11 is located in the clamping groove 203 of the first fixing clamp 2 and the second fixing clamp 6. Meanwhile, ensure that the second positioning hole 201 on the second fixing clamp 6 is aligned with the second positioning hole 201 on the first fixing clamp 2. Then, put the second rubber sleeve 7 on the screw 5, and pass the bottom end of the screw 5 through the through hole of the pressure plate 4, the second positioning hole 201 of the first fixing clamp 2 and the second fixing clamp 6 in sequence, and screw it into the positioning sleeve 101. Then, the operator gradually tightens the screw 5, so that the pressure plate 4 presses down to tighten the second rubber sleeve 7, thereby firmly fixing the second fixing clamp 6 on the first fixing clamp 2, ensuring that the gas pipeline 11 is firmly clamped. When the gas pressure or flow rate changes and causes the gas pipeline 11 to vibrate, the first rubber sleeve 3 and the second rubber sleeve 7 will be compressed, thereby absorbing the energy generated by the vibration of the gas pipeline 11, thereby reducing vibration and impact. The clamping action of the first fixing clamp 2 and the second fixing clamp 6, the shock absorption action of the first rubber sleeve 3 and the second rubber sleeve 7, and the connection with the hose 8 effectively reduce the vibration caused by changes in gas pressure or flow rate, further reducing the vibration energy transmitted to the gas collector, thereby reducing the risk of damage to the gas collector due to vibration, and reducing the possibility of loose joints, ensuring the accuracy and reliability of the observation data.
