Abstract

This invention discloses a portable shale gas desorption observation and automatic measurement device. Its structure includes a gas inlet pipe, a pressure valve, a sealing structure, a fixed base, and an observation mirror. The gas inlet pipe passes through the upper end of the sealing structure, the pressure valve is installed at the upper end of the sealing structure, and the observation mirror is engaged with the inner side of the sealing structure. The lower end of the sealing structure is embedded in the upper end of the fixed base. This invention observes the gas desorption inside the sealing structure through the observation mirror. Shale blocks placed on the upper surface of the elastic structure control the vibration of the vibration device at the upper end of the fixed plate, thereby applying force to the lower middle end of the elastic structure and turning over the shale blocks on the upper surface of the elastic structure, preventing the shale blocks from accumulating and obstructing the gas desorption.

Description

Technical Field

[0001] This invention relates to the field of portable measuring devices, and more specifically to a portable shale gas desorption observation and automatic measuring device. Background Technology

[0002] Shale gas is mainly found in shale as adsorbed gas and free gas. The selection of exploration sites for shale gas has attracted widespread attention, especially the issue of gas content, which is not only an important parameter for shale gas resource evaluation, but also a key parameter for calculating and predicting development indicators.

[0003] In the existing technology, portable shale gas desorption observation and automatic measurement devices are easy to carry and can automatically measure humidity and temperature in the air and detect their content, thereby calculating the variables of shale gas desorption.

[0004] Shale rocks contain natural gas, which disperses into the air as a gas when exposed to air. During measurement, the loose shale rocks tend to accumulate, resulting in poor gasification of the bottom shale rocks. Furthermore, the natural gas produced by shale gasification is in a sealed environment, and the pressure is measured directly based on the pressure value. The limited space inside a gasification tank of a certain volume can easily lead to high internal pressure. After the gas is released, a large reaction force can easily occur, which can damage the instruments inside the gasification tank and fail to meet the usage requirements. Summary of the Invention

The gas inlet pipe passes through the upper end of the sealing structure, the pressure valve is installed on the upper end of the sealing structure, the observation mirror is engaged with the inner side of the sealing structure, and the lower end of the sealing structure is embedded in the upper end of the fixed base.

[0006] The sealing structure includes a gasification tank, an elastic structure, a fixing plate, and a pneumatic structure. The pneumatic structure is installed in the middle of the upper end of the gasification tank and connected to a pressure valve. The fixing plate is engaged with the lower inner side of the gasification tank. The elastic structure is installed on the upper part of the fixing plate. A vibration device is provided on the upper part of the fixing plate. The pneumatic structure and the elastic structure are located on the same central axis. The lower end of the gasification tank is embedded in the upper end of the fixing base.

[0007] Preferably, the elastic structure includes a guide structure, a rubber block, a bending plate, and a force-bearing block. The guide structure is installed on the upper part of the fixed plate. The force-bearing block and the guide structure are located on the same central axis. The force-bearing block is connected to a vibration device and its up-and-down movement is controlled by the vibration device. The rubber block and the bending plate are arranged alternately. The rubber block is attached to the side of the bending plate. The rubber block and the bending plate are embedded between the guide structure and the force-bearing block.

[0008] Preferably, the bending plate is made of easily bendable rubber, and the rubber block is made of easily bendable aluminum alloy.

[0009] Preferably, the guiding structure includes a movable plate, an extrusion structure, and a connecting plate. The extrusion structure is located between the movable plate and the connecting plate, and the outer side of the extrusion structure is attached to the inner side of the connecting plate. The rubber block is embedded in the lower end of the movable plate.

[0010] Preferably, the extrusion structure includes a rubber sleeve, a magnetic block, and a spring. The two ends of the spring are embedded inside the rubber sleeve, the magnetic block is engaged inside the rubber sleeve and located at both ends of the spring, and the magnetic block is made of two magnets of different magnetic properties, so that they have mutual attraction. The outer side of the rubber sleeve is attached to the inner side of the connecting plate.

[0011] Preferably, the pressure structure includes a sensor, a support plate, a compression structure, and a bending structure. The support plate is installed at the middle of the upper end of the gasification tank. The support plate consists of two opposing support plates. The sensor is embedded in the inner upper part of the support plate. The bending structure is installed in the inner lower part of the support plate. The upper end of the compression structure is embedded in the lower end of the sensor, and the lower end is clearance-fitted with the upper end of the bending structure. The bending structure is installed in the inner lower part of the support plate.

[0012] Preferably, the bending structure includes a support block, a deformation sleeve, and a connecting rod. The deformation sleeve is a hollow structure. The support block fits inside the deformation sleeve. The connecting rod is engaged inside the left and right ends of the deformation sleeve. The ends of the connecting rods located at both ends of the bending structure are connected to the inner side of the lower end of the support plate.

[0013] Preferably, the compression structure includes a pressure block, an elastic plate, and a support ring, wherein the elastic plate is installed between the pressure block and the support ring, and the support ring is embedded in the lower end of the sensor.

[0014] Preferably, the pressure block is made of rubber.

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. This invention allows observation of the gas disintegration inside the sealed structure through an observation mirror. Shale blocks placed on the upper surface of the elastic structure are used to control the vibration of the vibration device at the upper end of the fixed plate, thereby applying force to the lower middle end of the elastic structure and turning over the shale blocks on the upper surface of the elastic structure. This prevents the gas disintegration of the shale blocks from being blocked by accumulation. During the movement of the rubber block, the movable plate forms a tensile force on the extrusion structure, providing a larger space for vibration and preventing the gas disintegration effect from being blocked after the shale blocks accumulate.

[0017] 2. In this invention, gas pressure in a sealed gasification tank exerts pressure on a bending structure and simultaneously applies force to the lower middle end of a compression structure. The pressure magnitude is sensed by a sensor inside the support plate, thereby generating a pressure value. After being subjected to force, the bending structure's deformation sleeve deforms under the force of gas pressure and rebounds under the elastic force of the elastic plate, preventing measurement deviations. This invention also creates space for the gas pressure inside the gasification tank, preventing excessive internal gas pressure while simultaneously measuring gas volume. Attached Figure Description

[0032] Example 1

[0033] like Figures 1-5 As shown, this embodiment discloses a portable shale gas desorption observation and automatic measurement device, whose structure includes a gas inlet pipe 1, a pressure valve 2, a sealing structure 3, a fixing base 4, and an observation mirror 5. The gas inlet pipe 1 passes through the upper end of the sealing structure 3, the pressure valve 2 is installed on the upper end of the sealing structure 3, the observation mirror 5 is snapped into the inner side of the sealing structure 3, the lower end of the sealing structure 3 is embedded in the upper end of the fixing base 4, and the sealing structure 3 is provided with a gas desorption tank 31, an elastic structure 32, a fixing plate 33, and a gas pressure structure 34. The gas pressure structure 34 is installed in the middle of the upper end of the gas desorption tank 31. The elastic structure 32 is installed on the upper end of the fixed plate 33, which is engaged with the lower end of the inner side of the gasification tank 31. The gas pressure structure 34 and the elastic structure 32 are located on the same central axis. The lower end of the gasification tank 31 is embedded in the upper end of the fixed seat 4. The inside of the gasification tank 31 is sealed. The upper end of the fixed plate 33 is equipped with a vibration device, which controls the vibration of the vibration device on the upper end of the fixed plate 33 to exert force on the lower middle end of the elastic structure 32, and to turn over the shale blocks on the upper surface of the elastic structure 32, so as to prevent the shale blocks from being blocked by accumulation during gasification.

[0034] The elastic structure 32 includes a guide structure 321, a rubber block 322, a bending plate 323, and a force-bearing block 324. The force-bearing block 324 and the guide structure 321 are located on the same central axis. The rubber block 322 and the bending plate 323 are staggered. The rubber block 322 is attached to the side of the bending plate 323 and embedded in the inner side of the guide structure 321. The guide structure 321 is installed on the upper end of the fixed plate 33. In this embodiment, there are five rubber blocks 322, which are evenly distributed around the force-bearing block 324. The bending plate 323 is made of rubber and has the characteristic of being easy to bend. The rubber block 322 is made of aluminum alloy and has the characteristic of being easy to bend and deform. The vibration device at the upper end of the fixed plate 33 controls the force-bearing block 324 to move up and down, so that the bending plate 323 can bend the shale on its surface through the rubber block 322, thereby achieving the effect of uniform force on the shale.

[0035] The guide structure 321 includes a movable plate a1, a compression structure a2, and a connecting plate a3. The outer side of the compression structure a2 is attached to the inner side of the connecting plate a3. The compression structure a2 is located on the outer side of the movable plate a1. The rubber block 322 is embedded in the lower end of the movable plate a1. The movable plate a1 is made of rubber and has a curved circular groove structure on its inner side, which has a friction blocking effect. Thus, during the movement of the rubber block 322, the movable plate a1 forms a pulling force on the compression structure a2. At the same time, the side of the movable plate a1 provides friction blocking to the shale block. The vibration generates a bumping effect on the compression movement of the compression structure a2, enhancing the dispersion vibration effect on the shale block.

[0036] The extrusion structure a2 includes a rubber sleeve a21, a magnetic block a22, and a spring a23. The spring a23 is embedded inside the rubber sleeve a21, and the magnetic block a22 is engaged inside the rubber sleeve a21. The outer side of the rubber sleeve a21 is attached to the inner side of the connecting plate a3. There are two magnetic blocks a22, which are made of different magnetic materials and have a mutual attraction force. Thus, when the rubber sleeve a21 is compressed by the vibration force, it deforms under the elastic force of the spring a23. At the same time, the attraction between the magnetic blocks a22 produces a rebound effect, forming a reciprocating elastic expansion and contraction effect, providing a larger space for vibration.

[0037] The specific usage and function of this embodiment are as follows:

[0038] In this embodiment, the gas disintegration inside the sealed structure 3 is observed through the observation mirror 5. Shale blocks placed on the upper surface of the elastic structure 32 are used to control the vibration device at the upper end of the fixed plate 33, thereby applying force to the lower middle part of the elastic structure 32 and causing the shale blocks on the upper surface of the elastic structure 32 to be turned over, preventing the gas disintegration of the shale blocks from being blocked by accumulation. Simultaneously, the vibration device at the upper end of the fixed plate 33 controls the force-bearing block 324 to move up and down, thereby causing the bending plate 323 to bump the shale on its surface through the rubber block 322, thus achieving uniform force distribution on the shale. The uniform effect allows the movable plate a1 to exert a pulling force on the extrusion structure a2 during the movement of the rubber block 322. As a result, the rubber sleeve a21 is compressed by the vibration force and deformed under the elastic force of the spring a23. At the same time, the attraction between the magnetic blocks a22 produces a rebound effect, forming a reciprocating elastic expansion and contraction effect, providing a larger space for vibration. Meanwhile, the side of the movable plate a1 provides frictional resistance to the shale block, and the vibration produces a bumpy effect on the compression movement of the extrusion structure a2, enhancing the dispersion vibration effect on the shale block and preventing the gasification effect from being blocked after the shale block accumulates.

[0039] Example 2

[0040] like Figures 6-8As shown, in this embodiment, the gas pressure structure 34 includes a sensor w1, a support plate w2, a compression structure w3, and a bending structure w4. The compression structure w3 is embedded in the lower end of the sensor w1, and the sensor w1 is embedded in the inner side of the support plate w2. The lower end of the compression structure w3 and the upper end of the bending structure w4 are fitted with a clearance. The bending structure w4 is installed on the inner side of the lower end of the support plate w2. The support plate w2 is installed in the middle of the upper end of the gas dissolution tank 31. The lower end of the compression structure w3 has an arc-shaped structure. The sensor w1 is equipped with a pressure sensor, so that the gas pressure in the sealed gas dissolution tank 31 generates pressure on the bending structure w4 and exerts a force on the lower middle end of the compression structure w3. The sensor w1 inside the support plate w2 senses the pressure magnitude and generates a pressure value.

[0041] The bending structure w4 includes a support block w41, a deformation sleeve w42, and a connecting rod w43. The support block w41 fits inside the deformation sleeve w42, and the connecting rod w43 is engaged inside the left and right ends of the deformation sleeve w42. The outer side of the connecting rod w43 is installed on the inner side of the lower end of the support plate w2. The deformation sleeve w42 is made of rubber and has the characteristic of easy deformation. Thus, the deformation sleeve w42 is deformed by the force of air pressure, which causes the support block w41 to exert force on the lower end of the compression structure w3. The amount of gas is measured according to the pressure value. The air pressure pushes the bending structure w4 to squeeze the compression structure w3, and the pressure on the compression structure w3 forms data that is fed back to the sensor w1, thereby measuring the gas.

[0042] The compression structure w3 includes a pressure block w31, an elastic plate w32, and a support ring w33. The outer side of the pressure block w31 is installed on the inner side of the elastic plate w32, and the outer side of the elastic plate w32 is engaged with the inner side of the support ring w33. The support ring w33 is embedded in the lower end of the sensor w1. The pressure block w31 is made of rubber and has a rebound effect under pressure. Thus, after the pressure block w31 is supported by pressure, it will have an inward effect through the elastic plate w32 on the inner side of the support ring w33, and at the same time, it will rebound under the elastic force of the elastic plate w32, avoiding jamming. This creates room for the gas pressure inside the gas dissolution tank 31, preventing excessive internal gas pressure while measuring gas volume.

[0043] The specific usage and function of this embodiment are as follows:

[0044] In this invention, gas pressure in the sealed gasification tank 31 exerts pressure on the curved structure w4 and simultaneously forces the lower middle end of the compression structure w3. The pressure magnitude is sensed by the sensor w1 inside the support plate w2, thus generating a pressure value. After being subjected to force, the deformation sleeve w42 of the curved structure w4 deforms under the force of gas pressure, causing the support block w41 to exert force on the lower end of the compression structure w3. The amount of gas is measured based on the pressure value. The gas pressure pushes the curved structure w4 to squeeze the compression structure w3, and the pressure data of the compression structure w3 is fed back to the sensor w1. At the same time, after the pressure block w31 is supported by pressure, it is indented by the elastic plate w32 inside the support ring w33. It also rebounds under the elastic force of the elastic plate w32 to prevent measurement deviation. This creates a space for the gas pressure inside the gasification tank 31 to prevent excessive internal gas pressure while measuring gas volume.

[0045] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
