Description

Technical Field

[0001] The present invention belongs to the technical field of gas pipeline joints, and specifically is an earthquake-resistant gas pipeline joint integrated with Internet of Things monitoring and an earthquake-resistant component thereof. Background Art

[0002] With the acceleration of urbanization, the safety and reliability of gas pipeline systems have become a top priority in urban infrastructure construction. Existing gas pipelines often suffer varying degrees of damage during earthquakes, and gas pipeline damage will affect people's lives. At the same time, gas leakage may bring a series of safety hazards. Generally speaking, the damaged part is the connection between the gas pipeline and the pipeline joint, which becomes loose or even broken under a large amplitude, resulting in gas leakage, making the entire gas pipeline network unable to operate normally, thereby causing secondary disasters such as fire and explosion.

[0003] For example, the patent with application number 2022106834251 discloses a gas pipeline joint with strong sealing performance, including a connecting cylinder and a connecting assembly, etc. The connecting cylinder is equipped with a connecting assembly, and the device squeezes the first sealing ring to the surface of the gas pipeline through a fixing nut to complete the primary sealing of the gas pipeline, and the fixing nut is limited and fixed by an elastic member to prevent the fixing nut from retreating due to vibration and causing gas leakage. The third sealing ring is linked to move toward the gas pipeline through the fixing nut, so that the third sealing ring is in close contact with the gas pipeline port to complete the secondary sealing, and the sealant is poured into the first cavity through the first circular tube to complete the tertiary sealing, which greatly improves the sealing effect. However, the above-mentioned pipeline joint lacks real-time monitoring function and cannot detect and handle abnormal situations in time.

[0004] The fixed connection between the traditional joint body and the gas pipeline results in poor seismic performance. The underground gas pipeline vibrates due to surrounding construction or vehicle pressure on the road surface, and the vibration causes the gas pipeline to shift in position, causing the elastic bellows to bend. If the degree of bending is too large, it will affect the stability of gas circulation; and the existing gas pipeline joints lack real-time monitoring functions, and cannot detect and handle abnormal situations in time, thus causing safety accidents; if a break occurs between the joint body and the gas pipeline, it will cause gas leakage in the gas pipeline, thus affecting gas safety.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example 1 like Figures 1 to 9 As shown, the present embodiment discloses an earthquake-resistant gas pipeline joint integrated with Internet of Things monitoring, including a connecting component 1, the connecting component 1 includes a joint body 101, a ball valve is arranged inside the joint body 101, and a gas flow sensor is installed on the ball valve, and the gas flow rate flowing through the joint body 101 is detected by the gas flow sensor, and mounting seats 102 are arranged at both ends of the joint body 101, an elastic bellows 103 is arranged at one end of the mounting seat 102 away from the joint body 101, a connecting pipe 104 is arranged at one end of the elastic bellows 103 away from the mounting seat 102, a sleeve 105 is installed at one end of the connecting pipe 104 away from the elastic bellows 103, and a gas pipeline 106 is arranged at one end of the sleeve 105 away from the connecting pipe 104.

[0022] Example 2 The present embodiment discloses an anti-seismic component, which is applied to the gas pipeline joint described in Example 1, and includes an elastic support component 2, a detection component 3 and a protective component 4. The elastic support component 2 is arranged below the connecting component 1, the detection component 3 is arranged in the middle position of the elastic bellows 103, and there are two protective components 4, which are mirror-imaged at both ends of the sleeve 105.

[0023] like Figure 3 As shown, the elastic support assembly 2 includes a first support seat 201, and first shock-absorbing springs 202 are arranged at the four corners of the first support seat 201. A joint bracket 203 is arranged at one end of the first shock-absorbing spring 202 away from the first support seat 201, and clamps 204 are arranged at both ends of the joint bracket 203, and the clamps 204 are adapted to the joint body 101.

[0024] A second support seat 205 is arranged on one side of the first support seat 201, and second shock-absorbing springs 206 are arranged at the four corners of the second support seat 205. A support 207 is arranged at the end of the second shock-absorbing spring 206 away from the second support seat 205, and a hydraulic lifting column 208 is arranged at the center position of the surface of the support 207. A correction clamping seat 209 is arranged at the end of the hydraulic lifting column 208 away from the support 207.

[0025] like Figure 4As shown, a buffer seat 2091 is provided on the inner wall of the correction clamping seat 209, and there are two buffer seats 2091. The two buffer seats 2091 are symmetrically arranged at the upper and lower ends of the correction clamping seat 209, and an arc groove compatible with the gas pipeline 106 is opened at one end of the buffer seat 2091 away from the correction clamping seat 209, and electric push rods 2093 are provided at both ends of the correction clamping seat 209, and an arc push plate 2092 compatible with the gas pipeline 106 is provided at one end of the output shaft of the electric push rod 2093, and elastic blocks are provided on the surfaces of the buffer seat 2091 and the arc push plate 2092.

[0026] When in use, during installation, the joint body 101 is first fixed by the clamp 204, and the gas pipeline 106 is fixed by the correction clamp seat 209. Specifically, one end of the gas pipeline 106 is first passed through the correction clamp seat 209, and the gas pipeline 106 is limited by the buffer seat 2091 and the arc push plate 2092. Then, the electric push rods 2093 on both sides of the gas pipeline 106 are controlled by the controller to extend at the same time, and the electric push rods 2093 push the arc push plate 2092 to contact the surface of the gas pipeline 106, so as to clamp and fix the gas pipeline 106, thereby ensuring that the center of the gas pipeline 106 and the center of the joint body 101 are in the horizontal direction. The two ends of the joint body 101 and the gas pipe 106 are in the same horizontal plane, and then the controller controls the hydraulic lifting column 208 to rise, so that the center of the gas pipe 106 in the correction clamping seat 209 and the center of the joint body 101 are in the same height in the vertical direction, which is convenient for subsequent connection. By setting the elastic bellows 103, the elastic bellows 103 itself has a certain elasticity and flexibility, which is used to improve the seismic performance of the connection between the joint body 101 and the gas pipe 106, that is, one end of the elastic bellows 103 is fixedly connected to one end of the joint body 101 through the mounting seat 102, and the other end of the elastic bellows 103 is fixedly connected to one end of the gas pipe 106 through the connection pipe 104 and the sleeve 105.

[0027] By providing structures such as the first support seat 201, the first shock-absorbing spring 202, the joint bracket 203 and the clamp 204, it is convenient to elastically support the joint body 101 and buffer the vibration of the joint body 101 caused by the outside world. By providing structures such as the second support seat 205, the second shock-absorbing spring 206, the support 207, the hydraulic lifting column 208 and the correction clamping seat 209, it is convenient to elastically support the gas pipeline 106 and buffer the vibration of the gas pipeline 106 caused by the outside world. At the same time, elastic blocks are provided on the surfaces of the buffer seat 2091 and the arc-shaped push plate 2092, which elastically buffer the gas pipeline 106 during vibration to avoid damage to the surface of the gas pipeline 106.

[0028] At the same time, the ground vibration caused by the earthquake will have a direct impact on the underground pipeline system. The pipeline joints are prone to rupture, leakage and other problems due to the direct impact of the seismic waves and the deformation of the pipeline system. The elastic support component 2 can enable the connection component 1 to withstand greater pressure and tension in sudden situations such as earthquakes, thereby ensuring the stability of the entire pipeline system. The joint body 101 and the gas pipeline 106 are flexibly connected through the elastic bellows 103, wherein the elastic bellows 103 can use its own elasticity to effectively alleviate the vibration and impact on the pipeline system, effectively solving the problem of poor seismic performance caused by the fixed connection between the traditional joint body 101 and the gas pipeline 106.

[0029] In addition, the gas flow rate flowing through the joint body 101 is detected by a gas flow sensor, and then compared with the gas flow rate flowing under normal conditions to determine whether a gas leak occurs at that location. If the gas flow sensor at the joint body 101 detects a gas leak at that location, the controller controls the ball valve to close and disconnect the gas supply.

[0030] Example 3 The inventors discovered that the underground gas pipeline 106 vibrates due to surrounding construction or vehicle pressure on the road surface, and the vibration causes the position of the gas pipeline 106 to shift, causing the elastic bellows 103 to bend. If the degree of bending is too large, it will affect the stability of gas circulation; and the above-mentioned existing gas pipeline joints lack real-time monitoring functions and cannot detect and handle abnormal situations in time, thereby causing safety accidents; if a break occurs between the joint body 101 and the gas pipeline 106, it will cause gas leakage in the gas pipeline 106, thereby affecting gas safety.

[0031] In order to solve the above problems, the anti-seismic assembly also includes: like Figure 5 , Figure 6 As shown, the detection component 3 includes a detection frame 301, which is arranged on the surface of the mounting seat 102, a detection seat 302 is arranged inside the detection frame 301, a detection spring 303 is arranged inside the detection seat 302, a movable rod 304 is arranged at the end of the detection spring 303 away from the detection seat 302, a detection pressure plate 305 is arranged at the end of the movable rod 304 away from the detection spring 303, an electromagnet is arranged inside the detection seat 302, a magnetic block is arranged inside the movable rod 304, and a pressure sensor is arranged inside the detection pressure plate 305.

[0032] There are four detection seats 302 , and the four detection seats 302 are arranged in a ring shape on the inner wall surface of the detection frame 301 .

[0033] During use, when the detection pressure plate 305 is squeezed by the elastic bellows 103, it means that the elastic bellows 103 is bent and deformed. During this process, the detection spring 303 is compressed, and the detection pressure plate 305 and the movable rod 304 move toward the detection seat 302. By setting a pressure sensor to detect the pressure exerted by the elastic bellows 103 on the detection pressure plate 305 at this time, the degree of bending of the elastic bellows 103 can be judged.

[0034] In addition, the controller controls the electromagnet to start and pass current, so that a magnetic repulsion force is generated between the electromagnet in the detection seat 302 and the magnetic block in the movable rod 304, so that the movable rod 304 overcomes the force of the detection spring 303 and moves in the direction close to the elastic bellows 103. The greater the current passed, the greater the magnetic repulsion force generated between the electromagnet in the detection seat 302 and the magnetic block in the movable rod 304.

[0035] like Figures 7 to 9 As shown, the protection component 4 includes a first wedge block 401, a second wedge block 402 is arranged below the first wedge block 401, connecting frames 403 are arranged on both sides of the second wedge block 402, a limiting column 404 is arranged below the connecting frame 403, a sealing seat 405 is arranged at the end of the limiting column 404 away from the connecting frame 403, an elastic folding plate 406 is arranged on the surface of the sealing seat 405, a limiting bracket 407 is arranged above the first wedge block 401, a fixed block 409 is arranged at the end of the limiting bracket 407 away from the first wedge block 401, and a hydraulic rod 408 is arranged at the end of the limiting bracket 407 away from the fixed block 409.

[0036] A sealing cavity is provided inside the sleeve 105, an elastic folding plate 406 is provided inside the sealing cavity, and the elastic folding plate 406 is provided on one side of the sealing cavity, one end of the elastic folding plate 406 away from the sealing seat 405 is fixedly connected to the sealing cavity, one end of the limiting column 404 away from the connecting frame 403 passes through and extends to the inside of the sealing seat 405, and a limiting hole is opened at the position where the limiting column 404 is connected to the sleeve 105.

[0037] A movable groove matching the second wedge block 402 is provided on the surface of the sleeve 105, and an elastic spring (not shown in the figure) is arranged inside the movable groove. The end of the elastic spring away from the movable groove is fixedly connected to the bottom end of the second wedge block 402, and the end of the hydraulic rod 408 away from the limiting bracket 407 is connected to the sleeve 105. The fixed block 409 is fixedly arranged on the surface of the connecting pipe 104.

[0038] When in use, the controller controls the hydraulic rod 408 to extend, and the hydraulic rod 408 pushes the limiting bracket 407 to move in the direction away from the sleeve 105, and the first wedge block 401 moves together with the limiting bracket 407. During this process, the first wedge block 401 squeezes the second wedge block 402, and the elastic spring is compressed, so that the second wedge block 402 moves along the movable groove in the direction close to the elastic spring, that is, the second wedge block 402 drives the connecting frame 403, the limiting column 404 and the sealing seat 405 to move together, so that the sealing seat 405 drives one end of the elastic folding plate 406 to move toward the center position of the sleeve 105, and under the action of the limiting column 404, the elastic folding plate 406 is unfolded to achieve the purpose of sealing the sleeve 105.

[0039] like Fig. 9 As shown, a card slot 4051 is opened on one side of the sealing seat 405, and a card block 4052 is set on the side of the sealing seat 405 away from the card slot 4051, and the card block 4052 is adapted to the card slot 4051, and the card block 4052 and the card slot 4051 are both set at one end of the sealing seat 405 away from the elastic folding plate 406.

[0040] It is worth noting that since there are two protective components 4, the two protective components 4 are mirror-imaged at the two ends of the sleeve 105, that is, there are two elastic folding plates 406 and two sealing seats 405, and the two sealing seats 405 are mirror-imaged, that is, the position of the slot 4051 on one of the sealing seats 405 corresponds to the position of the block 4052 on the other sealing seat 405, and while the sealing is achieved by respectively unfolding the two elastic folding plates 406, the sealing seat 405 is fixed by cooperating between the slot 4051 and the block 4052.

[0041] The bending state of the elastic bellows 103 is detected by the detection component 3, and the gas pipeline 106 is adjusted by the elastic support component 2, so as to ensure the horizontality of the elastic bellows 103, so that the gas can be normally transported during transportation. The following example is specifically as follows: When the elastic bellows 103 bends downward in the vertical direction, it indicates that the center height of the gas pipeline 106 at one end of the joint body 101 is lower than the center height of the joint body 101. At this time, the elastic bellows 103 squeezes the detection platen 305 located below the detection frame 301 in the vertical direction, and the detection spring 303 is compressed. During this process, the detection platen 305 and the movable rod 304 move toward the detection seat 302. At this time, the pressure sensor detects the pressure of the elastic bellows 103 on the detection platen 305. The larger the detection value of the pressure sensor, the greater the compression of the detection spring 303.

[0042] When the detection value of the pressure sensor exceeds the preset value, it indicates that the bending degree of the elastic bellows 103 is large. At this time, the hydraulic lifting column 208 is controlled to rise by the controller. The hydraulic lifting column 208 pushes the correction clamping seat 209 to move upward in the vertical direction, so that the end of the gas pipeline 106 close to the elastic bellows 103 rises. At this time, the bending degree of the elastic bellows 103 changes. At this time, the pressure sensor is used again to detect the pressure of the detection plate 305 exerted by the elastic bellows 103. If the detection value of the pressure sensor on the detection plate 305 is restored to the initial value, that is, the elastic bellows 103 is restored to a horizontal state, the gas in the gas pipeline 106 is in the best state when flowing through the joint body 101, that is, the gas flow rate detected by the gas flow sensor at this time The flow rate of the gas flowing through the joint body 101 is equal to the highest threshold value within the standard range.

[0043] If the detection value of the pressure sensor on the detection pressure plate 305 does not return to the initial value, it indicates that the center position height of the gas pipeline 106 at one end of the joint body 101 is greatly different from the center position height of the joint body 101. At this time, the normal transportation of gas cannot be met by adjusting the hydraulic lifting column 208 while ensuring that the gas pipeline 106 is not damaged. At this time, the current is adjusted according to the detection value of the pressure sensor on the detection pressure plate 305, so that the detection pressure plate 305 supports and corrects the elastic bellows 103. Specifically, the controller controls the electromagnet to start and pass When current is input, magnetic repulsion is generated between the electromagnet in the detection seat 302 and the magnetic block in the movable rod 304, so that the movable rod 304 overcomes the force of the detection spring 303 and moves toward the direction close to the elastic bellows 103, so that the detection pressure plate 305 under the elastic bellows 103 supports it, thereby reducing the bending degree of the elastic bellows 103. At this time, the gas in the gas pipeline 106 is in a relatively smooth flow state when flowing through the joint body 101, that is, at this time, the gas flow sensor detects that the gas flow flowing through the joint body 101 is within the standard range.

[0044] When the elastic bellows 103 is bent in the horizontal direction, the elastic bellows 103 will bend to the left or right in the horizontal direction (e.g. Figure 6 As shown), the axis of the gas pipeline 106 at one end of the joint body 101 is not on the same horizontal line as the axis of the joint body 101. For example, when the elastic bellows 103 bends to the right in the horizontal direction, it indicates that the end of the gas pipeline 106 close to the joint body 101 is offset to the right. At this time, the detection plate 305 on the right side of the elastic bellows 103 is squeezed and the detection spring 303 is compressed. During this process, the detection plate 305 and the movable rod 304 move toward the detection seat 302. At this time, the pressure sensor detects the pressure of the elastic bellows 103 on the detection plate 305.

[0045] When the detection value of the pressure sensor exceeds the preset value, it indicates that the bending degree of the elastic bellows 103 is large. At this time, the controller controls the electric push rod 2093 located on the right side of the gas pipeline 106 to extend, and the electric push rod 2093 pushes the arc push plate 2092 and the elastic block to move in the direction close to the gas pipeline 106, thereby applying thrust to the gas pipeline 106 for correction and changing the bending degree of the elastic bellows 103. At this time, the pressure sensor is used again to detect the pressure of the detection plate 305 exerted by the elastic bellows 103. If the detection value of the pressure sensor on the detection plate 305 is restored to the initial value, that is, the elastic bellows 103 is restored to a horizontal state, the gas in the gas pipeline 106 is in the best state when flowing through the joint body 101, that is, the gas flow rate detected by the gas flow sensor flowing through the joint body 101 is equal to the highest threshold value within the standard range.

[0046] If the detection value of the pressure sensor on the detection plate 305 does not return to the initial value, it indicates that the gas pipeline 106 has a large degree of displacement in the horizontal direction. At this time, adjusting the electric push rod 2093 cannot meet the demand. At this time, the current is adjusted according to the detection value of the pressure sensor on the detection plate 305, so that the left detection plate 305 squeezes the elastic bellows 103. Specifically, the controller controls the electromagnet to start and pass current, so that the electromagnet in the detection seat 302 and the magnetic block in the movable rod 304 generate magnetic repulsion, so that the movable rod 304 overcomes the The force of the detection spring 303 moves in the direction close to the elastic bellows 103, so that the detection pressure plate 305 on the left squeezes the elastic bellows 103, thereby reducing the bending degree of the elastic bellows 103, making the bending arc of the elastic bellows 103 larger, reducing the resistance to the gas flow, and at the same time reducing the impact of the gas on the elastic bellows 103 during circulation. The gas in the gas pipeline 106 is in a relatively smooth flow state when flowing through the joint body 101, that is, at this time, the gas flow sensor detects that the gas flow flowing through the joint body 101 is within the standard range.

[0047] It is worth noting that since the arc-shaped push plate 2092 and the elastic block in the correction clamping seat 209 elastically clamp the gas pipe 106, the gas pipe 106 will be displaced in the horizontal direction when it vibrates. Since the gas pipe 106 is long and tough, under the action of vibration, the uneven force on the gas pipe 106 will cause the end of the gas pipe 106 close to the elastic bellows 103 to shift in the vertical direction, thereby causing the elastic bellows 103 to bend and deform, affecting the normal circulation of gas.

[0048] In addition, during an earthquake, if the vibration caused by the earthquake is too large and exceeds the limit of the elastic bellows 103, it will cause a break between the joint body 101 and the gas pipeline 106. At this time, the vibration size is judged according to the predicted earthquake level. If the vibration caused by the earthquake is predicted to be too large and exceeds the limit of the elastic bellows 103, the controller will simultaneously control the two hydraulic rods 408 to extend, and the hydraulic rods 408 will push the limit bracket 407 to move away from the sleeve 105. The first wedge block 401 moves with the limit bracket 407. In this process, the first wedge block 401 squeezes the second wedge block 402, and the elastic spring is compressed, so that the second wedge block 402 is The wedge block 402 moves along the movable groove in the direction close to the elastic spring, that is, the second wedge block 402 drives the connecting frame 403, the limiting column 404 and the sealing seat 405 to move together, so that the sealing seat 405 drives one end of the elastic folding plate 406 to move toward the center position of the sleeve 105, so that the card grooves 4051 and the card blocks 4052 at the corresponding positions of the two sealing seats 405 cooperate to achieve card connection and fixation, and under the action of the limiting column 404, the elastic folding plate 406 is unfolded, that is, the two elastic folding plates 406 cooperate to achieve the purpose of sealing the sleeve 105, and at the same time avoid gas leakage inside the gas pipeline 106, thereby affecting gas safety.

[0049] In the above process, the hydraulic rod 408 pushes the limiting bracket 407, the fixing block 409 and the connecting pipe 104 to move towards the direction close to the elastic bellows 103, that is, the connecting pipe 104 slides on the sleeve 105, and the elastic bellows 103 is compressed. When the elastic bellows 103 is compressed to the limit, the joint body 101 and the gas pipeline 106 are transformed from a flexible connection to a fixed connection.

[0050] It is worth noting that during the vibration process, due to the long-term bending deformation of the elastic bellows 103 with the vibration, when the vibration amplitude is large, there will be no break between the joint body 101 and the gas pipeline 106. At this time, the controller simultaneously controls the two hydraulic rods 408 to extend, and the hydraulic rods 408 push the limit bracket 407, the fixed block 409 and the connecting pipe 104 to move in the direction close to the elastic bellows 103, that is, the connecting pipe 104 slides on the sleeve 105. During this process, the elastic bellows 103 is compressed, thereby increasing the tensile performance. At the same time, the distance between the connecting pipe 104 and the correction clamping seat 209 on the gas pipeline 106 changes, which is equivalent to extending the length of the gas pipeline 106, and the position of the support point of the correction clamping seat 209 on the gas pipeline 106 changes, thereby increasing the support strength for the gas pipeline 106.
