Description

Technical Field

[0001] This invention relates to the field of groundwater pressure monitoring, and more specifically, to a flange for fixing sensors inside pipelines. Background Technology

[0002] Groundwater pressure is a crucial safety indicator that many underground mines must pay attention to. It is used to prevent adverse geological disasters such as uneven settlement and collapse in mining areas that may occur during most underground mining operations, both domestically and internationally, due to groundwater pressure. To prevent unnecessary geological disasters caused by groundwater pressure during mining, it is necessary to accurately grasp the characteristics of groundwater pressure changes and to monitor and prevent underground mining safety more safely and efficiently. Water pressure sensors are often installed in underground water pipelines to monitor water pressure changes.

[0003] Existing pressure sensors typically involve first installing a permanent underground water pressure monitoring pipe on the underground water pipeline, then placing the sensor inside the permanent underground water pressure monitoring pipe, and finally connecting the permanent underground water pressure monitoring pipe to the sensor flange via threads. The sensor can then accurately monitor the underground water pressure, allowing mine personnel to provide early warnings of uneven settlement and collapse based on changes in water pressure. This can improve safety while reducing economic losses.

[0004] However, existing flanges used to fix sensors inside pipelines require users to spend time rotating screws to connect them during installation, and when the sensor is damaged, users need to spend time rotating the screws again to disassemble the flange. In addition, when installing and disassembling the flange, users also need to manually open and close the valves of the underground water pressure permanent monitoring pipeline, which seriously affects the efficiency of flange and sensor installation and disassembly. Summary of the Invention

[0010] Optionally, a sealing gasket is fixedly installed on the lower flange, a sealing groove that mates with the sealing gasket is opened on the upper flange, a first air chamber is opened on the sealing gasket, and an air supply component for supplying air to the first air chamber is provided on the mounting ring.

[0011] Optionally, the air supply assembly includes a first air pipe inserted into the bottom wall of the mounting ring, a first connecting hole communicating with the first air pipe is provided on the horizontal rod, and a second air pipe communicating with the first connecting hole is inserted into the first air chamber.

[0012] Optionally, an annular mounting groove is provided on the side wall of the sealing disc, an annular pad is installed in the mounting groove, and a second air chamber is provided on the annular pad. A third air pipe extending to the top wall of the mounting ring is inserted into the second air chamber. An exhaust valve with its output end connected to the outside is also inserted into the second air chamber. A fourth air pipe extending to the top wall of the mounting ring is fixedly installed on the output end of the exhaust valve. A control component for controlling the expansion of the annular pad is provided in the third air pipe.

[0013] Optionally, the control assembly includes an annular plate fixedly installed inside a third trachea, a third spring fixedly installed on the annular plate, a disc fixedly installed on the third spring, and a connecting rod fixedly installed on the top wall of the disc.

[0014] Optionally, a filter screen is fixedly installed inside the monitoring pipeline, a rotating rod is rotatably installed on the filter screen, a scraper is fixedly installed on the rotating rod, and a drive assembly for driving the rotating rod to rotate is provided on the sealing disc.

[0015] Optionally, the drive assembly includes a rotating block fixedly mounted on a sealing disc, and the rotating rod has a rotating groove that slides with the rotating block.

[0016] Optionally, the sensor body includes a display, a cable, and a sensor, and the display and the sensor are electrically connected via the cable. The sensor body is detachably mounted on the top wall of the upper flange. An upper threaded groove and a lower threaded groove are respectively provided on the inner wall of the upper flange. An upper gasket is installed in the inner thread of the upper threaded groove, and a lower gasket is installed in the inner thread of the lower threaded groove. An upper rubber plug is provided between the bottom wall of the upper gasket and the upper threaded groove, and a lower rubber plug is provided between the top wall of the lower gasket and the lower threaded groove.

[0017] Optionally, the inclined surface of the inclined block is a smooth mirror surface.

[0018] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0019] In the above solution, by cooperating with the horizontal and vertical rods, when installing the upper flange, the vertical rod is first aligned with the vertical groove and the upper flange is pushed downwards. Then, the vertical rod drives the fixing groove to contact the inclined block. At this time, the horizontal rod drives the inclined block to fix the vertical rod. When the sensor body needs to be replaced, the upper flange can be disassembled simply by pulling the horizontal rod outwards. This saves time in disassembling and installing the sensor body and improves the efficiency of upper flange installation and disassembly.

[0020] By setting a sealing disc, when the user removes the upper flange, the upper flange causes the first push rod and the second push rod to disengage. At this time, the second spring drives the sealing disc to seal the slide groove through the mounting ring and the mounting rod. When the upper flange is installed, the upper flange drives the sealing disc to disengage from the slide groove through the first push rod and the second push rod. This eliminates the need for the user to manually open and close the monitoring pipeline valves, further improving the efficiency of upper flange installation and disassembly.

[0021] By setting a sealing gasket, during the installation of the upper flange, the mounting ring can move downwards, compressing the gas located below the mounting ring in the annular cavity. The gas then flows into the first gas chamber through the gas supply assembly, causing the sealing gasket to expand. The top wall of the expanded sealing gasket gradually enters the sealing groove, thereby increasing the contact area between the upper and lower flanges and thus increasing the stability between them. At the same time, the expansion of the sealing gasket can also increase the sealing performance between the upper and lower flanges, thereby increasing the accuracy of the sensor body's monitoring and preventing poor sealing performance between the upper and lower flanges, which would require reinstallation, further improving the installation efficiency of the upper flange.

[0022] By setting up a control component, when the upper flange and lower flange are fitted together, the second spring contracts and drives the first connecting hole to contact the first air pipe through the horizontal rod. At this time, the gas in the space below the mounting ring in the annular cavity flows into the first air chamber through the first air pipe, the first connecting hole, and the second air pipe. That is, the sealing gasket can only expand after the upper flange is installed, which effectively prevents the sealing strip from expanding prematurely, causing the resistance between the upper flange and the lower flange to increase and affecting the installation efficiency of the upper flange and the lower flange, thus improving the installation efficiency of the upper flange and the lower flange.

[0048] like Figures 1 to 8 As shown, this embodiment of the invention provides a flange for fixing a sensor inside a pipeline, including an underground water pipe 1 and a sensor body 2. A monitoring pipe 3 is fixedly installed on the underground water pipe 1 and the monitoring pipe 3 is connected to the underground water pipe 1. A lower flange 4 is fixedly installed on the monitoring pipe 3, and an upper flange 5 connected to the lower flange 4 is provided on the sensor body 2.

[0049] It also includes a connecting component 6, which includes horizontal grooves symmetrically formed on the lower flange 4. A horizontal rod 601 is slidably installed in the horizontal groove. A first spring 602 is fixedly installed between the horizontal rod 601 and the horizontal groove. A vertical groove communicating with the horizontal groove is formed on the lower flange 4. A vertical rod 603 that slides with the vertical groove is fixedly installed on the upper flange 5. A linkage groove 604 is formed on the horizontal rod 601. An inclined block 605 is fixedly installed in the linkage groove 604. The top wall of the inclined block 605 is inclined. A fixing groove 606 that cooperates with the inclined block 605 is formed on the vertical rod 603. A sealing component 7 is provided in the monitoring pipeline 3.

[0050] The sealing assembly 7 includes a first push rod 701 symmetrically fixedly installed on the bottom wall of the upper flange 5. An annular cavity 702 is provided on the monitoring pipe 3. An installation ring 703 is slidably and sealingly installed in the annular cavity 702. A second spring 704 is fixedly installed between the top wall of the installation ring 703 and the annular cavity 702. Installation rods 705 are uniformly fixedly installed on the installation ring 703. A sliding groove 707 is provided on the underground water pipe 1. A sealing disc 706 fixedly connected to the installation rod 705 is slidably installed in the sliding groove 707. A limiting groove is provided on the monitoring pipe 3 to slide with the first push rod 701. A second push rod 708 to slide with the limiting groove is fixedly installed on the top wall of the sealing disc 706.

[0051] Initially, the first spring 602 is in a freely extended state. In use, first align the vertical rod 603 with the vertical groove, then push the upper flange 5 downwards. As the upper flange 5 moves downwards, it drives the vertical rod 603 downwards along the vertical groove. During this downward movement, the vertical rod 603 gradually contacts the inclined surface of the inclined block 605, applying a pushing force to the inclined surface. Under this pushing force, the inclined block 605 drives the horizontal rod 601 to move outwards along the horizontal groove. At this point, the first spring 602 is stretched and has a restoring function. As the vertical rod 603 moves downward, it drives the fixing groove 606 downward. When the bottom wall of the upper flange 5 is in contact with the top wall of the lower flange 4, the vertical rod 603 drives the fixing groove 606 to contact the inclined block 605. At this time, the first spring 602 contracts and drives the inclined block 605 to move into the fixing groove 606 through the horizontal rod 601. Then, under the action of the inclined block 605 and the fixing groove 606, the vertical rod 603 cannot move, that is, the upper flange 5 and the lower flange 4 are fixed. Thus, the sensor body 2 can be fixed without rotating the threaded rod.

[0052] When the sensor body 2 is damaged and needs to be replaced, the user can first pull the horizontal bar 601 outward. Then, the horizontal bar 601 will cause the inclined block 605 to disengage from the fixing groove 606. At this time, the user can pull the upper flange 5 upward, causing the sensor body 2 to disengage from the detection pipeline. When the upper flange 5 disengages from the lower flange 4, the sealing component 7 can seal the monitoring pipeline 3. Then, the user can replace the sensor body 2. That is, only by pulling the horizontal bar 601, the upper flange 5 can be removed and the damaged sensor body 2 can be replaced. This saves the user time in disassembling and installing the sensor body 2 and improves the efficiency of installing and removing the upper flange 5.

[0053] When the sensor body 2 needs to be replaced, as the user pulls the upper flange 5 upward, the second spring 704 contracts and, through the mounting ring 703 and mounting rod 705, drives the sealing disc 706 upward. After the sensor body 2 disengages from the lower flange 4, the sealing disc 706 contacts the slide groove 707 and seals it. This means the sealing disc 706 can then seal the monitoring pipeline 3, eliminating the need for manual closure of the valve on the monitoring pipeline 3. When installing the upper flange 5, the user can first insert the first push rod 701 into the limiting groove to position the upper flange 5 and lower flange 4, facilitating installation. Then, as the upper flange 5 moves downward, it drives the first push rod 701 downward. During the downward movement of the first push rod 701... The first push rod 701 gradually contacts the second push rod 708 and applies a downward pushing force to it. Under the action of the pushing force, the first push rod 701 drives the second push rod 708 to move downward. During the downward movement of the second push rod 708, the sealing disc 706 moves downward. During the downward movement of the sealing disc 706, the mounting ring 703 moves downward along the annular cavity 702 via the mounting rod 705. At this time, the second spring 704 is stretched and has a tendency to return to its original state. When the pressure sensor body 2 contacts the lower flange 4, the sealing disc 706 disengages from the slide groove 707. At this time, the monitoring pipeline 3 is connected to the underground water pipe 1 through the slide groove 707, thus eliminating the need for manual valve opening. In other words, by setting the sealing disc 706, the efficiency of the installation and disassembly of the upper flange 5 is further improved by eliminating the need for manual valve opening and closing.

[0054] like Figures 2 to 5 As shown, a sealing gasket 801 is fixedly installed on the lower flange 4, and a sealing groove that mates with the sealing gasket 801 is provided on the upper flange 5. A first air chamber 802 is provided on the sealing gasket 801, and an air supply component 803 for supplying air to the first air chamber 802 is provided on the mounting ring 703.

[0055] The air supply assembly 803 includes a first air pipe 8031 ​​inserted into the bottom wall of the mounting ring 703, a first connecting hole 8032 communicating with the first air pipe 8031 ​​on the horizontal rod 601, and a second air pipe 8033 communicating with the first connecting hole 8032 inserted into the first air chamber 802.

[0056] By adopting the above technical solution, when the mounting ring 703 moves downward along the annular cavity 702, the gas pressure in the space below the mounting ring 703 in the annular cavity 702 increases. Then, under the action of the pressure, the gas in the space below the mounting ring 703 in the annular cavity 702 flows into the first gas chamber 802 through the gas supply component 803, causing the sealing gasket 801 to expand. Then, the top wall of the expanded sealing gasket 801 gradually enters the sealing groove, thereby increasing the contact area between the upper flange 5 and the lower flange 4, thus increasing the stability between the upper flange 5 and the lower flange 4. At the same time, the expansion of the sealing gasket 801 can also increase the sealing performance between the upper flange 5 and the lower flange 4, thereby increasing the accuracy of the sensor body 2 monitoring, and can also prevent poor sealing performance between the upper flange 5 and the lower flange 4, which would require reinstallation of the upper flange 5 and the lower flange 4, further improving the installation efficiency of the upper flange 5.

[0057] Initially, the second spring 704 is in a stretched state, meaning that the horizontal rod 601 causes the first connecting hole 8032 to disengage from the first air pipe 8031. This prevents the gas in the space below the mounting ring 703 within the annular cavity 702 from flowing into the first air chamber 802. When the upper flange 5 and lower flange 4 are fitted together, the second spring 704 contracts and, through the horizontal rod 601, causes the first connecting hole 8032 to contact the first air pipe 8031. At this point, the gas in the space below the mounting ring 703 within the annular cavity 702 flows into the first air chamber 802 through the first air pipe 8031, the first connecting hole 8032, and the second air pipe 8033. This means that the sealing gasket 801 can only expand after the upper flange 5 is installed, effectively preventing premature expansion of the sealing strip from increasing the resistance between the upper flange 5 and lower flange 4 and affecting the installation efficiency of the upper flange 5 and lower flange 4. This improves the installation efficiency of the upper flange 5 and lower flange 4.

[0058] When disassembling the upper flange 5, as the user pulls the horizontal bar 601, the first spring 602 is stretched and tends to return to its original position. At this time, the user can pull the upper flange 5 upward. During the upward movement of the upper flange 5, the first push rod 701 and the second push rod 708 are disengaged. At this time, the second spring 704 contracts and drives the mounting ring 703 upward. During the upward movement of the mounting ring 703, the pressure in the annular cavity 702 below the mounting ring 703 decreases. Then, after the vertical bar 603 disengages from the vertical groove, the user can release the horizontal bar 601. At this time, the first spring 602 contracts and drives the first connecting hole 8032 to contact the first air pipe 8031 ​​again through the horizontal bar 601. At this time, under the action of pressure, the space in the annular cavity 702 below the mounting ring 703 draws air from the first air chamber 802 through the first air pipe 8031, the first connecting hole 8032, and the second air pipe 8033, and causes the sealing gasket 801 to reset, which serves to prepare for the next operation.

[0059] like Figure 5 and Figure 7 As shown, an annular mounting groove is provided on the side wall of the sealing disc 706. An annular pad 901 is installed in the mounting groove, and a second air chamber 902 is provided on the annular pad 901. A third air pipe 903 extending to the top wall of the mounting ring 703 is inserted into the second air chamber 902. An exhaust valve 904 with its output end connected to the outside is also inserted into the second air chamber 902. A fourth air pipe 905 extending to the top wall of the mounting ring 703 is fixedly installed on the output end of the exhaust valve 904. A control component 906 for controlling the expansion of the annular pad 901 is provided inside the third air pipe 903.

[0060] The control component 906 includes an annular plate 9061 fixedly installed inside the third air pipe 903, a third spring 9062 fixedly installed on the annular plate 9061, a disc 9063 fixedly installed on the third spring 9062, and a connecting rod 9064 fixedly installed on the top wall of the disc 9063.

[0061] By adopting the above technical solution, during the process of the second spring 704 contracting and moving the sealing disc 706 upward through the mounting ring 703 and mounting rod 705, the gas pressure above the mounting ring 703 in the annular cavity 702 increases, and flows into the second gas cavity 902 through the third gas pipe 903. Then, under the action of the gas, the annular pad 901 expands and fits tightly against the side wall of the slide groove 707, further increasing the sealing performance between the sealing disc 706 and the slide groove 707.

[0062] Initially, the third spring 9062 is stretched, and the top wall of the disc 9063 is tightly fitted with the annular plate 9061. This means that the gas in the annular cavity 702 cannot flow into the second gas chamber 902 through the third air pipe 903. Then, as the mounting ring 703 moves upward, it drives the control component 906 upward via the third air pipe 903. During this upward movement, the connecting rod 9064 gradually contacts the top wall of the annular cavity 702. After the sealing disc 706 is reset by the plate 9061, the top wall of the annular cavity 702 drives the disc 9063 to disengage from the annular plate 9061 through the connecting rod 9064. At this time, the gas in the space above the mounting ring 703 in the annular cavity 702 flows to the second air chamber 902 through the third air pipe 903, and causes the annular gasket 901 to expand, thereby further improving the sealing effect between the sealing disc 706 and the slide groove 707, and further preventing water leakage in the underground water pipe 1 when the upper flange 5 is replaced.

[0063] When the mounting ring 703 moves downward, the space above the mounting ring 703 in the annular cavity 702 draws air from the second air chamber 902 through the fourth air pipe 905 and the air inlet valve, causing the annular pad 901 to contract and reset, thereby reducing the resistance of the sealing disc 706 moving downward and also reducing the wear of the annular pad 901.

[0064] like Figure 5 and Figure 6 As shown, a filter screen 101 is fixedly installed inside the monitoring pipe 3, a rotating rod 102 is rotatably installed on the filter screen 101, a scraper 103 is fixedly installed on the rotating rod 102, and a drive assembly 104 for driving the rotating rod 102 to rotate is provided on the sealing disc 706.

[0065] The drive assembly 104 includes a rotating block 1041 fixedly mounted on the sealing disc 706, and the rotating rod 102 has a rotating groove 1042 that slides with the rotating block 1041.

[0066] By adopting the above technical solution, when the water flows through the chute 707 to the monitoring pipe 3, the water will pass through the filter screen 101. At this time, the filter screen 101 can filter the impurities in the water flow, thereby effectively preventing the impurities in the water flow from contacting the sensor body 2 and adhering to the surface of the sensor body 2, affecting the accuracy of the monitoring data of the sensor body 2, and playing a role in improving the accuracy of the monitoring data.

[0067] During the movement of the sealing disc 706, the rotating block 1041 will move. During the movement of the rotating block 1041, the rotating rod 102 will rotate through the rotating groove 1042. During the rotation of the rotating rod 102, the scraper 103 will rotate. During the rotation of the scraper 103, the impurities on the bottom wall of the filter screen 101 can be cleaned. This effectively prevents the impurities on the bottom wall of the filter screen 101 from affecting the normal water flow and contacting the sensor body 2, thus preventing inaccurate monitoring data and further improving the accuracy of the monitoring data.

[0068] like Figure 3 As shown, the sensor body 2 includes a display 21, a cable 22, and a sensor 23. The display 21 and the sensor 23 are electrically connected through the cable 22. The sensor body 2 is detachably mounted on the top wall of the upper flange 5. The inner wall of the upper flange 5 is provided with an upper threaded groove and a lower threaded groove. An upper gasket 111 is installed in the upper threaded groove, and a lower gasket 112 is installed in the lower threaded groove. An upper rubber plug 113 is provided between the bottom wall of the upper gasket 111 and the upper threaded groove, and a lower rubber plug 114 is provided between the top wall of the lower gasket 112 and the lower threaded groove.

[0069] By adopting the above technical solution, when it is necessary to replace the sensor body 2, the user can first pass the cable 22 through the center holes of the upper gasket 111, upper rubber plug 113, lower rubber plug 114, and lower gasket 112 in sequence, and connect the two ends of the cable 22 to the display 21 and the sensor 23 respectively. Then, the upper rubber plug 113 is placed into the upper threaded groove, and the upper gasket 111 is moved downward along the upper threaded groove. During the movement of the upper gasket 111, the upper rubber plug 113 will be squeezed and deformed. When the upper rubber plug 113 is squeezed to the maximum degree of deformation, the user can place the lower rubber plug 114 into the lower threaded groove. The lower gasket 112 moves along the lower thread groove towards the upper gasket 111. During the movement of the lower gasket 112, the lower rubber plug 114 is squeezed. During the deformation of the upper rubber plug 113 and the lower rubber plug 114, the cable 22 is squeezed and clamped. Then, the user can put the sensor 23 into the monitoring pipe 3 and install the new upper flange 5 and lower flange 4. Through the cooperation of the upper rubber plug 113 and the lower rubber plug 114, the upper rubber plug 113 and the lower rubber plug 114 can be in close contact with the cable 22, thereby improving the fixing effect of the cable 22 and reducing the wear of the cable 22.

[0070] like Figure 8 As shown, the inclined surface of the inclined block 605 is a smooth mirror surface.

[0071] By adopting the above technical solution, during the process of the vertical rod 603 driving the horizontal rod 601 to move through the inclined block 605, there will be friction between the vertical rod 603 and the inclined surface of the inclined block 605. By making the inclined surface of the inclined block 605 a smooth mirror surface, the coefficient of friction between the inclined block 605 and the vertical rod 603 can be reduced, thereby reducing the friction between the vertical rod 603 and the inclined block 605. This ensures that the vertical rod 603 can drive the inclined block 605 to move normally, and at the same time, it can also reduce the degree of wear between the vertical rod 603 and the inclined block 605.

[0072] The working process of the technical solution provided by this invention is as follows:

[0073] First, install the sensor body 2 on the upper flange 5. Then, align the vertical rod 603 with the vertical groove and push the upper flange 5 downward. As the upper flange 5 moves downward, the vertical rod 603 drives the fixing groove 606 to contact the inclined block 605. At this time, the first spring 602 drives the inclined block 605 to insert into the fixing groove 606 through the horizontal rod 601. At this time, the upper flange 5 is installed.

[0074] Then, when it is necessary to replace the sensor body 2, first pull the horizontal bar 601 and make the inclined block 605 disengage from the fixing groove 606. At this time, the user can disassemble the upper flange 5. At the same time, during the movement of the upper flange 5, the second spring 704 drives the sealing plate 706 to seal the monitoring pipe 3 through the mounting ring 703 and the mounting rod 705.

[0075] During the installation of the upper flange 5, the upper flange 5 drives the sealing disc 706 to move downward through the first push rod 701 and the second push rod 708. During the downward movement of the sealing disc 706, the mounting ring 703 can be driven to move downward, and the gas in the space below the mounting ring 703 in the annular cavity 702 is squeezed. Then the squeezed gas flows into the first gas chamber 802 through the gas supply assembly 803, thereby causing the sealing gasket 801 to expand, thereby increasing the sealing performance between the upper flange 5 and the lower flange 4.

[0076] Furthermore, by setting up the filter screen 101, impurities in the water flow can be filtered to prevent them from adhering to the sensor body 2. Then, during the up-and-down movement of the sealing disc 706, the scraper 103 can be driven by the rotating block 1041, the rotating groove 1042, and the rotating rod 102 to clean the impurities on the filter screen 101.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0078] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
