Description

A pressure detection device for gas reservoir type gas storage Technical Field

[0001] This utility model relates to the field of pressure detection technology, specifically to a pressure detection device for a gas reservoir-type gas storage facility. Background Technology

[0002] Gas reservoir-type gas storage facilities are natural gas storage facilities converted from underground natural gas reservoirs, playing a crucial role in the storage, distribution, and supply of natural gas. They utilize depleted natural gas reservoirs or specially designed gas-bearing strata, storing and releasing natural gas through injection and extraction. The principle involves using the pores and fissures in the underground rock as storage spaces, injecting natural gas into them, and extracting it through wells when needed. The gas pressure in the storage facility must be checked before each use to prevent safety accidents.

[0003] The prior art disclosed in CN222579477U is a pressure monitoring device for a gas storage facility, which solves the problem that existing pressure transmitters cannot withstand the high pressure inside the gas storage facility, making it difficult to monitor the pressure. The device includes a pressure transmitter with a pressure tap connected to one end and a cable connected to the other end; a protective cover fitted over the pressure transmitter; the pressure tap and the cable passing through the protective cover; a lead hole on the pressure tap connecting the pressure transmitter to the external environment of the protective cover; and sealant filled between the protective cover, the pressure tap, and the cable to seal the gaps between them.

[0004] However, the existing gas storage pressure monitoring device has shortcomings. For example, it lacks a fixing structure. When the gas storage pressure monitoring device is inserted into the gas storage to detect pressure, it cannot be fixed, resulting in unstable detection pressure. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a gas storage pressure detection device for gas reservoirs, which solves the technical problem that the gas storage pressure monitoring device cannot be fixed during the process of being inserted into the gas storage to detect pressure, resulting in unstable detection pressure.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0021] Figure 2 is a side view of the gas storage pressure monitoring device provided in an embodiment of this utility model. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] To address the technical problem in existing gas storage pressure monitoring devices that cannot be fixed during pressure detection, leading to unstable pressure readings, this invention provides a gas reservoir-type gas storage pressure detection device. This device can fix the pressure sensor at a target position when it is inserted into the gas storage, enabling the pressure sensor to stably detect the pressure in the gas storage, resulting in stable and accurate pressure detection.

[0024] It should be noted that the gas reservoir pressure detection device described in this utility model is used for, but not limited to, detecting the pressure of the gas reservoir. For ease of explanation, this utility model only uses the application of the gas reservoir pressure detection device to detect the pressure of the gas reservoir as an example. The principle of the gas reservoir pressure detection device applied to other types of equipment is essentially the same as that applied to the gas reservoir, and will not be described in detail here.

[0025] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the structure of a gas reservoir pressure detection device in one embodiment of the present invention. The gas reservoir pressure detection device includes a pressure detection component 1 and a positioning component 2. The pressure detection component 1 includes a moving part 11 and a pressure sensor 12. The moving part 11 has an extension end that can extend into the gas reservoir. The pressure sensor 12 is located at the extension end of the moving part 11 so that when the moving part 11 extends into the gas reservoir, the pressure sensor 12 can enter the gas reservoir to detect the pressure of the gas reservoir.

[0026] The positioning component 2 includes a first airbag component 21 and a first air tube (not shown in the figure). The first airbag component 21 is sleeved on the extension end of the moving component 11. It can be understood that the first airbag component 21 and the pressure sensor 12 are arranged close to each other so that the first airbag component 21 can fix the pressure sensor 12 when it expands and abuts against the inner wall of the air storage tank. One end of the first air tube is connected to the first airbag component 21.

[0027] In this embodiment, the pressure sensor 12 is mounted on the moving part 11. When detecting the pressure of the gas storage tank 4, the moving part 11 can be extended into the gas storage tank 4, and the pressure sensor 12 follows the moving part 11 into the gas storage tank 4 to facilitate the detection of the pressure of the gas storage tank 4. After the moving part 11 extends the pressure sensor 12 to the target depth of the gas storage tank 4, an air pump is used to inflate the first air tube, thereby inflating the first airbag 21 through the first air tube. This causes the first airbag 21 to expand and abut against the inner wall of the gas storage tank 4, thereby fixing the moving part 11 and the pressure sensor 12, so that the pressure sensor 12 can stably detect the pressure of the gas storage tank 4.

[0028] In one embodiment, referring to Figure 1, the pressure detection assembly 1 further includes a pressure display 13, which is located at the end of the moving part 11 away from the pressure sensor 12. The moving part 11 has a lead wire hole 111, which connects the pressure display 13 and the pressure sensor 12. In this embodiment, the lead wire hole 111 is used to accommodate a wire, and the two ends of the wire are respectively connected to the pressure display 13 and the pressure sensor 12, so that the pressure data of the gas storage tank 4 detected by the pressure sensor 12 can be transmitted to the pressure display 13 for display by the staff.

[0029] In one embodiment, referring to Figure 1, the moving part 11 is provided with a groove, and the first air tube is disposed in the groove, with the other end of the first air tube exposed to the outside air. In this embodiment, the first air tube is secured in the groove, making it convenient to use. The end of the first air tube exposed to the outside air can be used to connect to an air pump, so that the air pump can inflate the first airbag part 21 through the first air tube when it is working.

[0030] In one embodiment, referring to Figure 1, the positioning assembly 2 further includes a fixed bracket 23 and a sealing gasket 24. The moving component 11 is slidably connected to the fixed bracket 23, and the sealing gasket 24 is disposed at the bottom of the fixed bracket 23. In this embodiment, the fixed bracket 23 can be placed at the outlet of the gas storage tank 4, and the edge of the gas storage tank 4 can be sealed using the sealing gasket 24 to improve the accuracy of pressure measurement in the gas storage tank 4. The middle part of the sealing gasket 24 is open for the moving component 11 to pass through, so that the moving component 11 can be inserted into the gas storage tank 4. The moving component 11 is slidably connected to the fixed bracket 23 so that it can slide stably back and forth along the fixed bracket 23 to stably adjust the pressure of the pressure sensor 12 in the gas storage tank 4.

[0031] In one embodiment, referring to Figure 1, the pressure detection device for a gas storage tank further includes a drive assembly 3 mounted on a fixed support 23. The drive assembly 3 is connected to a moving component 11 and is used to drive the moving component 11 to slide back and forth relative to the fixed support 23. In this embodiment, the drive assembly 3 is mainly used to provide power to the moving component 11 so that the moving component 11 can slide back and forth along the fixed support 23, adjusting the depth of the pressure sensor 12 in the gas storage tank 4, so as to detect the pressure at different depths of the gas storage tank 4.

[0032] In one embodiment, referring to Figures 1 and 2, the drive assembly 3 includes a drive motor 31 and a rack 32. The rack 32 is mounted on the fixed bracket 23 along the sliding direction of the moving member 11. The drive motor 31 has a drive gear 311, which meshes with the rack 32. In this embodiment, the drive motor 31 is connected to the moving member 11 and can slide synchronously with it. When working, the drive motor 31 drives the drive gear 311 to rotate. When rotating, the drive gear 311 meshes with the rack 32, and the reaction force exerted by the rack 32 on the drive gear 311 drives the drive motor 31 to move, thereby driving the moving member 11 to slide back and forth. In other embodiments, the moving member 11 can also be driven to slide back and forth by a cylinder telescopic rod or by a servo motor using a lead screw.

[0033] In one embodiment, referring to Figure 1, the first airbag component 21 includes a first sleeve 211 and a first bladder body 212. The first sleeve 211 is fitted onto the moving component 11, and the first bladder body 212 is fitted onto the outer wall of the first sleeve 211. The first bladder body 212 is connected to a first air tube. In this embodiment, the first sleeve 211 and the first bladder body 212 are fixedly connected, for example, by bonding with strong adhesive. The first sleeve 211 and the moving component 11 are also fixedly connected, for example, by welding. Before the first airbag component 21 is inserted into the air reservoir 4, the first bladder body 212 is not filled with gas and is in a deflated state, so that the first airbag component 21 can be smoothly inserted into the air reservoir 4. When the target position is reached, the first bladder body 212 is inflated, so that the first bladder body 212 expands and abuts against the inner wall of the air reservoir 4, locking in the current position. At this time, the pressure sensor 12 on the moving component 11 can also be fixed in the current position.

[0034] In one embodiment, referring to FIG1, the positioning component 2 further includes a second airbag 25, which is connected to the moving component 11 and located on the side of the first airbag 21 facing away from the pressure sensor 12. In this embodiment, the second airbag 25 and the moving component 11 can slide relative to each other, and the second airbag 25 can be used to act as a pre-positioning element to assist in the stable fixation of the first airbag 21.

[0035] Further, referring to Figure 1, the second airbag component 25 includes a second sleeve 251 and a second bladder body 252. The second sleeve 251 is fitted onto the moving component 11, and the second bladder body 252 is fitted onto the outer wall of the second sleeve 251. In this embodiment, the inner wall of the second sleeve 251 has multiple friction protrusions, which slightly abut against the outer wall of the moving component 11 without affecting the sliding of the moving component 11 relative to the second sleeve 251. At the same time, the second sleeve 251 can also provide a certain frictional limiting effect on the moving component 11, preventing the second airbag component 25 from easily sliding relative to the moving component 11 and failing to be fixed in the target position. The second bladder 252 can be made of highly elastic plastic. After expansion, the second bladder 252 abuts against the inner wall of the gas storage tank 4. The friction between the second bladder 252 and the inner wall of the gas storage tank 4 is much greater than the friction between the moving part 11 and the first sleeve 211. Therefore, the moving part 11 can still slide back and forth relative to the second sleeve 251 under the action of external force, so as to adjust the height of the pressure sensor 12.

[0036] In one embodiment, the moving component 11 is provided with distance scale lines along its direction of movement. In this embodiment, by providing distance scale lines on the moving component 11, it is convenient to observe the depth of the pressure sensor 12 in the gas storage tank 4 and detect the pressure at different depths in the gas storage tank 4.

[0037] To better understand this utility model, the technical solution of this utility model will be described in detail below with reference to Figures 1 and 2:

[0038] The gas reservoir pressure detection device provided by this utility model has a moving component that allows one end of a pressure sensor 12 to extend into the gas reservoir 4, enabling the pressure sensor 12 to detect the pressure of the gas reservoir 4. A first airbag 21 is located on the moving component 11 and close to the pressure sensor 12. A first air pipe connects to the first airbag 21, and an air pump can be connected to the first air pipe to inflate the first airbag 21. When inflated, the first airbag 21 abuts against the inner wall of the gas reservoir 4, thus fixing the moving component 11 and the pressure sensor 12 located on it. The pressure sensor 12 detects pressure stably and accurately. After detection, the moving component 11 can be removed from the gas reservoir by deflating the first airbag 21 through the first air pipe, making it convenient to use.
