Description

Technical Field

[0001] The present invention relates to the technical field of outdoor natural gas pipeline leakage, and more particularly to a pipeline leakage detection device. Background Art

[0002] A natural gas pipeline is a pipeline that transports natural gas from extraction sites or processing plants to urban distribution centers or industrial users. Using natural gas pipelines is a method of transporting large quantities of natural gas on land.

[0003] In actual situations, during the laying process of natural gas pipelines, many natural gas pipelines are laid directly outdoors. At the same time, the natural gas pipelines are exposed to the outside world. In the connection of natural gas pipelines, flange connections are generally used to ensure the transportation of natural gas. However, during the use of natural gas pipelines, the connection of the flange is easily affected by impurities such as rain and dust and rusts. This can easily lead to gas leakage at the connection of the flange in the natural gas pipeline, resulting in a waste of natural gas and a certain amount of resources.

[0004] Therefore, we propose a pipeline leakage detection device to solve the above problems. Summary of the Invention

[0007] This device can detect leakage at the connection of the natural gas pipeline. When a natural gas leakage is detected, the connection of the natural gas pipeline can be sealed. At the same time, the protective sleeve can seal the surrounding position of the natural gas connection when installed, and further can perform double sealing on the natural gas connection, thereby avoiding continuous leakage of natural gas and further avoiding waste of resources.

[0010] In a preferred embodiment, the sealing assembly includes a protective rubber ring mounted on the inner sidewall of the protective sleeve. Two symmetrical waterstop rings are fixedly connected to the sidewalls of the protective rubber ring, and a blocking block is inserted into the protective rubber ring. The sidewalls of the protective rubber ring and the sidewalls of the waterstop ring respectively contact the sidewalls of the pipe. The protective rubber ring is provided with a water reservoir, and the sidewalls of the water reservoir are provided with a water inlet that matches the blocking block.

[0011] When the protective rubber ring is attached to the pipe, the user can fill the protective rubber ring with water to further avoid leakage of natural gas. At the same time, under the action of the water stop ring, water leakage can be avoided, thereby improving the sealing effect of the device.

[0012] In a preferred embodiment, the control assembly includes a fixed plate fixedly connected to the side wall of the protective sleeve, the fixed plate having a control module fixedly connected thereto, a first control button fixedly connected to the side wall of the fixed plate, the fixed plate being bent, and the first control button being located on the opposite side of the protective sleeve.

[0013] When natural gas leaks, the movable rod can be moved accordingly, so that the rubber column can contact the first control button, thereby starting the control module, so that the information sending module in the control module can send relevant information to the background, further ensuring that relevant staff receive the information, thereby facilitating the staff to carry out maintenance.

The two second control buttons are respectively located below the limit plate, and the magnetic ring is magnetically connected to the flange.

[0015] When the movable rod moves, the closing ring can be located at the connection of the pipe flange. With the assistance of the magnetic ring, the water stop ring can be fitted to the connection of the flange, so that the connection of the pipe flange can be sealed, thereby achieving a sealing effect and further improving the practicality of the device.

[0017] When the water stop ring enters the corresponding position, the second control button is squeezed, which enables the electromagnet to work, so that the leak-proof plug can be moved, and further water can enter the water stop ring, thereby playing a sealing role and further improving the sealing effect of the device.

[0018] The technical effects and advantages of the present invention are as follows:

[0019] This device can protect outdoor natural gas pipelines, thereby increasing the sealing effect of the natural gas pipelines, further preventing the natural gas pipeline flange connections from being easily eroded by rainwater, thereby protecting the natural gas pipeline flange connections, further extending the service life of the natural gas pipeline flange connections, and indirectly improving the practicality of the device.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 、 Figure 5 and Figure 6 A pipeline leakage detection device includes two pipelines 1, and the two pipelines 1 are installed together through a flange. It is particularly noteworthy that the two pipelines 1 are natural gas pipelines, and the two natural gas pipelines are outdoor pipelines. At the same time, the flange contains iron elements, so that they can be adsorbed by the magnetic lock.

[0035] Reference Figure 5 and Figure 6 Two protective sleeves 2 are sleeved on the two pipes 1, and the two protective sleeves 2 are movably connected. Two first fixing plates 3 are fixedly connected to one of the protective sleeves 2, and two second fixing plates 4 are fixedly connected to the other protective sleeve 2. It is particularly noteworthy that the first fixing plate 3 and the second fixing plate 4 are welded to the protective sleeves 2, and the two first fixing plates 3 are threadedly connected with fixing screws 5 threadedly connected to the second fixing plates 4. With the help of the fixing screws 5, the two protective sleeves 2 can be fixed on the pipes 1, thereby ensuring the installation of the device. One of the protective sleeves 2 is provided with an air-stop groove 6, and the other protective sleeve 2 is fixedly connected with an air-stop plate 7 matching the air-stop groove 6. When the two protective sleeves 2 are fitted together, the air-stop plate 7 can enter the air-stop groove 6, thereby increasing the sealing effect of the protective sleeves 2.

[0036] In actual operation, the staff can put the two protective sleeves 2 on the connection position of the outdoor natural gas pipeline according to the actual outdoor conditions, and at the same time rotate the fixing screws 5, so that the first fixing plate 3 and the second fixing plate 4 can be fitted together, thereby fixing the two protective sleeves 2 together, and further enabling the device to be used normally.

[0037] Reference Figure 5 and Figure 6 Two sealing assemblies are provided on each of the two protective sleeves 2. The sealing assembly includes a protective rubber ring 8 arranged on the inner wall of the protective sleeve 2. Two symmetrical water stop rings 9 are fixedly connected to the side wall of the protective rubber ring 8. A blocking block 10 is inserted into the protective rubber ring 8. The side walls of the protective rubber ring 8 and the side walls of the water stop ring 9 are in contact with the side walls of the pipe 1 respectively. A water storage groove is provided in the protective rubber ring 8, and a water inlet matching the blocking block 10 is provided on the side wall of the water storage groove.

[0038] In actual operation, when the two protective sleeves 2 are installed on the pipe 1, the two protective rubber rings 8 can be fitted on the pipe 1, and the water stop ring 9 can also be fitted on the pipe 1. Then the staff uses a syringe to inject water into the protective rubber ring 8. First, the staff inserts the injection needle into the water inlet, and then presses the syringe, so that the water source can enter the water storage tank, thereby making the sealing effect of the protective rubber ring 8 better. At the same time, the water stop ring 9 can not only play a waterproof effect, but also prevent natural gas leakage.

[0039] Reference Figure 2 、 Figure 3 and Figure 4 , both protective sleeves 2 are connected to a control component, which includes a fixing plate 11 fixedly connected to the side wall of the protective sleeve 2, the fixing plate 11 is bent, and a control module 12 is fixedly connected to the fixing plate 11. It is particularly noteworthy that the control module 12 includes an information sending module, a GPS positioning module, a single-chip microcomputer and a power supply module, wherein the information sending module can send the natural gas leakage situation to the background, thereby achieving the purpose of reminding the staff to repair, and the GPS positioning module can facilitate the staff to locate the relevant position, the power supply module can provide power for other components, and the single-chip microcomputer can control other components. A first control button 13 is fixedly connected to the side wall of the fixing plate 11, and the first control button 13 is on the opposite side of the protective sleeve 2.

[0040] In actual operation, when the first control button 13 is pressed due to the movement of the moving rod 14, the first control button 13 will start the microcontroller, so that the information sending module and the GPS positioning module will work accordingly, so that the staff can be reminded, which further facilitates the staff's maintenance, and other components can also work accordingly.

[0041] Reference Figure 5 and Figure 6 , both protective sleeves 2 are provided with a moving assembly, which includes a moving rod 14 that is arranged through the protective sleeve 2, and a push plate 15 is sleeved on the moving rod 14, and two first contraction springs 16 are fixedly connected to the side wall of the push plate 15. The first contraction spring 16 has the purpose of resetting the push plate 15, so that the device can be used normally next time. One end of the two first contraction springs 16 is respectively fixedly connected to the side wall of the protective sleeve 2, and one end of the moving rod 14 is fixedly connected to a rubber column 17. It is particularly noteworthy that the rubber column 17 has the purpose of protecting the first control button 13. The rubber column 17 is on one side of the first control button 13, and the moving rod 14 is connected to the closing assembly 18.

[0042] In actual operation, when natural gas leakage occurs at the connection of the pipeline 1, since the protective sleeve 2 can prevent the leakage of natural gas, the natural gas in the protective sleeve 2 can increase, so that the push plate 15 can be affected by the natural gas and move accordingly, so that the moving rod 14 can move accordingly, thereby moving the rubber column 17, and then the rubber column 17 can contact the first control button 13, so that the single-chip microcomputer can work accordingly, further facilitating the staff to repair it.

[0043] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9, the moving assembly is connected to a closing assembly 18, which includes a closing ring 181 fixedly connected to one end of the moving rod 14. It is particularly noteworthy that the closing ring 181 is located on one side of the flange connection of the pipeline 1. Therefore, when the closing ring 181 moves, the closing ring 181 can be located exactly at the connection of the flange, thereby achieving a sealing effect on the pipeline 1. A limiting plate 182 is connected above the closing ring 181. The limiting plate 182 is composed of a horizontal plate and a vertical rod, and one end of the vertical rod passes through the side wall of the closing ring 181 and is connected to the water stop ring 184. The lower end of the limiting plate 182 is fixedly connected to two second contraction plates connected to the closing ring 181. Spring 183, it is particularly noteworthy that the second contraction spring 183 has the purpose of resetting the water stop ring 184, a water stop ring 184 is provided in the closed ring 181, and the upper end of the water stop ring 184 is fixedly connected with two magnetic rings 185, it is particularly noteworthy that the magnetic ring 185 is magnetically connected to the flange, so that the water stop ring 184 can fit into the connection of the flange, and two sealing rings 186 are fixedly connected to the side wall of the water stop ring 184, and two mounting columns 187 are fixedly connected to the upper end of the closed ring 181, and two second control buttons 188 are fixedly connected to the upper ends of the two mounting columns 187, and the two second control buttons 188 are respectively located below the limit plate 182.

[0044] In actual operation, when the moving rod 14 moves, the closed ring 181 moves accordingly. When the closed ring 181 moves to the connection of the flange, it is particularly noteworthy that there are two magnetic rings 185. When one magnetic ring 185 is on one side of the flange, the water stop ring 184 will not move. Therefore, when the two magnetic rings 185 are on one side of the flange, the closed ring 181 is just at the connection of the flange. With the assistance of the magnetic ring 185, the water stop ring 184 can be fitted to the connection of the flange, so that the sealing ring 186 can be on both sides of the connection of the flange, thereby achieving a sealing effect on the connection of the flange. At the same time, the limit plate 182 moves accordingly, and further enables the limit plate 182 to contact the second control button 188, so that the electromagnet 195 can be operated through the single-chip microcomputer, so that the device can be used normally.

[0045] Reference Figure 8 and Figure 10, the closure assembly 18 is connected to two storage assemblies 19, the storage assembly includes a storage box 191 fixedly connected to the closure ring 181, and the two storage boxes 191 are both inserted with a rubber plug 192, wherein the rubber plug 192 is convenient for the staff to use a syringe with a bent needle to add water, and further enables the water source to be filled into the storage box 191, and two vertical rods 193 are fixedly connected to the inner bottom of the storage box 191, and the two vertical rods 193 are both sleeved with a spring 194, and the two vertical rods 193 are sleeved with the same There is a leak-proof plug 196, one end of which extends to the output end of the storage box 191. The upper ends of the two vertical rods 193 are fixedly connected to the same electromagnet 195, and the electromagnet 195 is magnetically connected to the leak-proof plug 196. It is particularly noteworthy that the output end of the storage box 191 is connected to the delivery pipe, and the output end of the delivery pipe is connected to the water stop ring 184, which further enables the water source to enter the water stop ring 184. The upper and lower ends of the two springs 194 are respectively connected to the electromagnet 195 and the leak-proof plug 196.

[0046] In actual operation, when the electromagnet 195 is working, the leak-proof plug 196 can be moved on the vertical rod 193, so that the leak-proof plug 196 can be separated from the water outlet of the storage box 191, and then the water source can enter the delivery pipe, so that the water source can enter the water stop ring 184, further improving the sealing effect of the water stop ring 184 and further satisfying the sealing of the device.
