Description

Technical Field

[0001] The utility model relates to the technical field of SF6 and O2 concentration online monitoring, in particular to an SF6 and O2 concentration online monitoring device. Background Art

[0002] SF6 and O2 concentration online monitoring equipment is a device used to monitor the concentration of sulfur hexafluoride (SF6) and oxygen (O2) in the environment in real time. It is widely used in the power, chemical and other industries, especially in power equipment using SF6 as insulation and arc extinguishing medium. By integrating multiple gas sensing technologies, it can simultaneously and accurately monitor the concentration of SF6 and O2.

[0003] The SF6 and O2 concentration online monitoring equipment produced by some manufacturers adopts an integrated design, integrating SF6 and O2 sensors, data acquisition modules, alarm control units, etc. in one housing. It can simultaneously monitor the concentration of SF6 and O2 and monitor environmental conditions in real time. It is widely used in gas analysis, industrial process control, environmental testing, power plants, substations and other fields.

[0004] Online monitoring equipment relies on high-precision sensors to detect the concentration of SF6 and O2. Over time, the performance of sensors may degrade due to dust accumulation, aging of electronic components, etc., thus affecting the accuracy of measurement data. Regular inspection and maintenance can timely detect and calibrate these problems to ensure the reliability of measurement data. However, when the SF6 and O2 concentration online monitoring equipment is integrated and installed in the same housing, the space between the various components of the equipment (such as sensors, circuit boards, connecting wires, etc.) is relatively compact. The limited space makes it difficult for maintenance personnel to perform inspection and maintenance operations on them, increasing the difficulty and complexity of operation. Utility Model Content

[0005] The purpose of the utility model is to provide an SF6 and O2 concentration online monitoring device to solve the problem raised in the above background technology that when the SF6 and O2 concentration online monitoring devices are integrated and installed in the same housing, the space between the various components of the equipment (such as sensors, circuit boards, connecting wires, etc.) is relatively compact, and the limited space makes it inconvenient for maintenance personnel to perform maintenance operations on them, which increases the difficulty and complexity of the operation.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] An online monitoring device for SF6 and O2 concentrations, comprising a shell; a bottom plate is slidably mounted at the bottom of the shell, bolts are inserted at both sides of the shell, each bolt is threadedly connected to the inner wall of the bottom plate, a protective door is rotatably mounted at one end of the shell, an adjustment frame is slidably connected to the top of the bottom plate, a screw rod is rotatably mounted inside the adjustment frame, a second mounting plate is threadedly connected to the outer surface of the screw rod, a pair of first mounting plates are fixedly mounted on the outer surface of the adjustment frame at the bottom of the second mounting plate, and a pair of third mounting plates are fixedly connected to the outer surface of the adjustment frame at the top of the second mounting plate;

[0008] A fixing component for fixing the position of the adjustment frame is arranged on the top of the bottom plate at the bottom of each mounting plate, and a limiting component for limiting the position of the adjustment frame is arranged on the top of the bottom plate at one end of each fixing component.

[0009] When the SF6 and O2 concentration online monitoring devices are integrated and installed in the same housing as proposed in the background technology, the spaces between the various components of the equipment, such as sensors, circuit boards, connecting wires, etc., are relatively compact. The limited space easily makes it inconvenient for maintenance personnel to perform maintenance operations on them, which increases the difficulty and complexity of the operation. In the present application, by rotating the bottom plate and the housing, the bottom plate can be moved to one end so that a part of it is moved out of the interior of the housing, and then the adjustment frame is moved out of the interior of the housing, and by rotating the adjustment frame and the bottom plate, after the fixed component is separated from the adjustment frame, the adjustment frame can be moved to one end for a distance. Thereby, the distance between the adjustment frame and the shell is further expanded; and by threading the screw rod and the mounting plate 2, the mounting plate 2 can be driven to move to the top or bottom by rotating the screw rod, and the distance between the mounting plate 2 and the mounting plate 1 and the mounting plate 3 can be adjusted to adapt to the sizes of components for online monitoring of SF6 and O2 concentrations of different sizes, so as to separate them by a certain distance, thereby expanding the contact space between the operator and the mounting plate 1, the mounting plate 2 and the mounting plate 3, so as to facilitate the inspection and maintenance of the components for online monitoring of SF6 and O2 concentrations installed on the mounting plate 1, the mounting plate 2 and the mounting plate 3, thereby improving the convenience of operation.

[0010] A further improvement of the technical solution of the utility model is that each fixing component includes a fixing frame, the bottom of each fixing frame is fixedly connected to the surface of the bottom plate, a card block is slidably installed inside each fixing frame through a spring, a side of each card block away from the spring extends to the outside of the fixing frame, and each card block is inserted into the inside of the adjustment frame, and a slope is provided on the side of each card block away from the spring.

[0011] The above-mentioned technical scheme is adopted. In this scheme, the elastic force of spring 1 itself can form an outward thrust on the card block, so that part of the card block moves out of the interior of the fixed frame and is stuck in the adjustment frame, thereby limiting the position of the adjustment frame on the top of the base plate, thereby improving the stability of the SF6 and O2 concentration online monitoring components installed on the mounting plate 1, mounting plate 2 and mounting plate 3, and ensuring their normal use. By providing an inclined surface on the surface of the card block, when the adjustment frame is located at one end of the card block and moves to the other end, the adjustment frame can just contact the inclined surface of the card block first, and then squeeze the inclined surface of the card block, so that the card block moves toward the interior of the fixed frame, so that the adjustment frame moves to the position outside the fixed frame, without the need for the operator to pull the card block inward first, reducing the operating steps, and thus facilitating the movement and limitation of the adjustment frame.

[0012] A further improvement of the technical solution of the utility model is that each limiting component includes a connecting frame, the bottom of each connecting frame is fixedly connected to the surface of the bottom plate, the interior of each connecting frame is slidably installed with a limiting block through spring 2, the side of each limiting block away from spring 2 extends to the outside of the connecting frame, and each limiting block is provided with an inclined surface on the side away from spring 2.

[0013] The above-mentioned technical scheme is adopted. In this scheme, after the adjusting frame is moved to one end and moved to the position outside the limiting component, the elastic force of the spring 2 itself can form an outward thrust on the limiting block, so that part of the limiting block moves out of the interior of the connecting frame and is stuck in the adjusting frame, thereby realizing the limitation of the position of the adjusting frame on the top of the bottom plate, thereby improving the stability of the SF6 and O2 concentration online monitoring components installed on the mounting plate 1, the mounting plate 2 and the mounting plate 3, and ensuring that the operating personnel can normally inspect and maintain them. By providing an inclined surface on the surface of the limiting block, when the adjusting frame is located at the other end of the limiting block and moves to one end, the adjusting frame can just contact the inclined surface of the limiting block first, and then squeeze the inclined surface of the limiting block, so that the limiting block moves toward the interior of the connecting frame, so that the adjusting frame moves to the position outside the connecting frame. There is no need for the operator to pull the limiting block inward first, thereby reducing the operation steps, thereby facilitating the movement and limitation of the adjusting frame.

[0014] A further improvement of the technical solution of the utility model is that a connecting block is fixedly installed at the bottom of the adjustment frame inside a pair of fixed components, and the connecting block is slidably connected to the inner wall of the bottom plate. A pressing block is slidably installed inside the bottom plate at one end of the connecting block through spring four, and a pushing block is slidably connected inside the bottom plate at the other end of the connecting block through spring three, and one end of the pushing block is pressed against the surface of the connecting block.

[0015] The above-mentioned technical scheme is adopted, in which the push block can be pushed toward one end by the elastic force of the spring three itself. When each clamping block is separated from the interior of the adjusting frame, the spring three can squeeze the push block, so that the push block squeezes the connecting block toward one end for a distance, so that the clamping block and the adjusting frame are misaligned. At this time, the clamping block can no longer be stuck in the adjusting frame, so that the operator can free his hands to move the adjusting frame. The elastic force of the spring four itself can be pushed toward the other end of the pressing block. When each limit block is separated from the interior of the adjusting frame, the spring four can squeeze the pressing block, so that the pressing block squeezes the connecting block toward the other end for a distance, so that the limit block and the adjusting frame are misaligned. At this time, the limit block can no longer be stuck in the adjusting frame, so that the operator can free his hands to move the adjusting frame.

[0016] The further improvement of the technical solution of the utility model is that: a plurality of fixing plates are fixedly installed inside the outer shell of the top of the adjustment frame, a slider is slidably installed inside each fixing plate, and the bottom of each slider is fixedly connected to the surface of the adjustment frame.

[0017] The above technical solution is adopted. In this solution, the slider is slidingly arranged between the slider and the fixed plate, and the slider and the adjustment frame are fixedly connected. When the adjustment frame moves to the inside of the shell, the slider can be inserted into the inside of the fixed plate, and the sliding trajectory of the adjustment frame inside the shell can be guided and limited, thereby reducing the possibility of the adjustment frame bending at both ends or both sides.

[0018] A further improvement of the technical solution of the utility model is that: rotating rods are rotatably installed on both sides of the adjustment frame, and the outer surface of each rotating rod is drivingly matched with the inner wall of the shell.

[0019] The above technical solution is adopted. In this solution, by transmission cooperation between the rotating rod and the shell, the rotating rod can rotate between the adjustment frame and the shell, and the rotating rod can also slide along the surface of the shell. When the adjustment frame moves, the rotating rod can slide and rotate along the moving trajectory of the adjustment frame, thereby guiding and limiting the sliding trajectory of the adjustment frame to a certain extent, thereby improving the smooth sliding effect of the adjustment frame.

[0020] A further improvement of the technical solution of the utility model is that: a card plate is fixedly installed on the top of each mounting plate 1, a guide piece is slidably connected inside each card plate, and a number of protrusions 2 are attached inside the card plate on both sides of each guide piece; a card strip is fixedly installed on the bottom of each mounting plate 3, a traction piece is slidably connected inside each card strip, and a number of protrusions 1 are attached inside the card strip on both sides of each traction piece; a number of limit pieces are fixedly installed on the top and bottom of the mounting plate 2.

[0021] The above-mentioned technical scheme is adopted. In this scheme, by installing the traction member, the guide member and the limit member, the placement position of the line or pipeline of the SF6 and O2 concentration online monitoring component can be guided and limited, and the guide member and the traction member can be moved inside the card plate and the card strip respectively according to different actual installation requirements. At the same time, the protrusion 2 and the protrusion 1 are made of deformable and resilient rubber material. The protrusion 2 and the protrusion 1 can be used to limit the guide member and the traction member respectively, and the position of the line and the pipeline can be adjusted, thereby reducing the possibility of entanglement of the line and the pipeline, ensuring that the SF6 and O2 concentrations can be monitored online normally.

[0022] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0023] 1. The utility model provides an SF6 and O2 concentration online monitoring device. After removing the bolts, a part of the bottom plate can be moved out of the interior of the shell by rotating the bottom plate and the shell, and then the adjustment frame can be moved out of the interior of the shell. After the fixing component is separated from the adjustment frame, the adjustment frame can be moved to one end by rotating the adjustment frame and the bottom plate, so as to further expand the distance between the adjustment frame and the shell. By rotating the screw rod, the mounting plate 2 is moved to the top or bottom, and the distance between the mounting plate 2 and the mounting plate 1 and the mounting plate 3 is adjusted to adapt to the sizes of components for online monitoring of SF6 and O2 concentrations of different sizes, so as to conveniently separate them by a certain distance, expand the contact space between the operator and the mounting plate 1, the mounting plate 2 and the mounting plate 3, so as to facilitate the inspection and maintenance of the components for online monitoring of SF6 and O2 concentrations installed on the mounting plate 1, the mounting plate 2 and the mounting plate 3, and improve the convenience of operation.

[0024] 2. The utility model provides an online monitoring device for SF6 and O2 concentrations. Through the mutual cooperation between spring three and the push block, when the card block is pulled to separate it from the inside of the adjusting frame, the spring three can squeeze the push block and the connecting block at the same time, so that the card block and the adjusting frame are dislocated, and the card block can no longer be stuck in the adjusting frame; through the mutual cooperation between spring four and the pressure block, when the limit block is pulled to separate it from the inside of the adjusting frame, the spring four can squeeze the pressure block and the connecting block at the same time, so that the limit block and the adjusting frame are dislocated, and the limit block can no longer be stuck in the adjusting frame, thereby facilitating the operator to free up his hands to move the adjusting frame.

[0025] 3. The utility model provides an online monitoring device for SF6 and O2 concentrations. By arranging a slider and a fixed plate, after the adjustment frame moves to the inside of the shell, the slider can be stuck in the inside of the fixed plate, thereby providing auxiliary support for the adjustment frame and reducing the possibility of the adjustment frame bending at both ends or both sides; by arranging a rotating rod, when the adjustment frame moves, the rotating rod can slide and rotate along the moving trajectory of the adjustment frame, thereby guiding and limiting the sliding trajectory of the adjustment frame to a certain extent, further improving the smooth sliding effect of the adjustment frame.

[0043] In this embodiment, when the SF6 and O2 concentration online monitoring devices proposed in the background technology are integrated and installed in the same housing, the space between the various components of the equipment such as sensors, circuit boards, connecting wires, etc. is relatively compact, and the limited space easily makes it inconvenient for maintenance personnel to perform maintenance operations on them, increasing the difficulty and complexity of the operation. In this application, by rotating the bottom plate 2 and the outer shell 1, the bottom plate 2 can be moved to one end so that a part of it is moved out of the interior of the outer shell 1, and then the adjustment frame 7 is moved out of the interior of the outer shell 1, and by rotating the adjustment frame 7 and the bottom plate 2, after the fixing component 5 is separated from the adjustment frame 7, the adjustment frame 7 can be moved to one end for a distance, so that The distance between the adjustment frame 7 and the housing 1 is further enlarged, and the contact space between the operator and the mounting plate 1 9, the mounting plate 2 10 and the mounting plate 3 11 is enlarged; and by threading the screw rod 8 and the mounting plate 2 10, the mounting plate 2 10 can be driven to move to the top or bottom by rotating the screw rod 8, and the distance between the mounting plate 2 10 and the mounting plate 1 9 and the mounting plate 3 11 is adjusted to adapt to the sizes of components for online monitoring of SF6 and O2 concentrations of different sizes, so as to separate them by a certain distance, so as to facilitate the inspection and maintenance of the components for online monitoring of SF6 and O2 concentrations installed on the mounting plate 1 9, the mounting plate 2 10 and the mounting plate 3 11, thereby improving the convenience of operation.

[0044] Example 2

[0045] like Figure 3 , Fig. 9 and Fig.10 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, each fixing component 5 includes a fixing frame 501, and the bottom of each fixing frame 501 is fixedly connected to the surface of the bottom plate 2, and the interior of each fixing frame 501 is slidably mounted with a clamping block 502 through a spring 1 503, and the side of each clamping block 502 away from the spring 1 503 extends to the outside of the fixing frame 501, and each clamping block 502 is clamped into the interior of the adjustment frame 7, and the side of each clamping block 502 away from the spring 1 503 is provided with an inclined surface, and each limiting component 6 includes a connecting frame 601, and the bottom of each connecting frame 601 is fixedly connected to the surface of the bottom plate 2 A limiting block 602 is slidably installed inside each connection frame 601 through a spring second 603, and a side of each limiting block 602 away from the spring second 603 extends to the outside of the connection frame 601. A slope is provided on the side of each limiting block 602 away from the spring second 603. A connecting block 22 is fixedly installed at the bottom of the adjustment frame 7 inside a pair of fixed components 5. The connecting block 22 is slidably connected to the inner wall of the bottom plate 2. A pressing block 26 is slidably installed inside the bottom plate 2 at one end of the connecting block 22 through a spring fourth 25. A pushing block 24 is slidably connected inside the bottom plate 2 at the other end of the connecting block 22 through a spring third 23. One end of the pushing block 24 is pressed against the surface of the connecting block 22.

[0046] In this embodiment, the elastic force of the spring 1 503 itself can form an outward thrust on the card block 502, so that part of the card block 502 moves out of the interior of the fixed frame 501 and is stuck in the adjustment frame 7, thereby limiting the position of the adjustment frame 7 on the top of the bottom plate 2, thereby improving the stability of the SF6 and O2 concentration online monitoring components installed on the mounting plate 1 9, the mounting plate 2 10 and the mounting plate 3 11, and ensuring their normal use, wherein by providing an inclined surface on the surface of the card block 502, when the adjustment frame 7 is located at one end of the card block 502 and moves to the other end, the adjustment frame 7 can just contact the inclined surface of the card block 502 first, thereby squeezing the inclined surface of the card block 502, so that the card block 502 moves to The internal movement of the fixed frame 501 facilitates the adjustment frame 7 to move to the position outside the fixed frame 501, and the operator does not need to pull the clamping block 502 inward first, which reduces the operation steps, thereby facilitating the movement and limiting of the adjustment frame 7; when the adjustment frame 7 is moved to one end, after the adjustment frame 7 is moved to the position outside the limiting component 6, the elastic force of the spring 2 603 itself can form an outward thrust on the limiting block 602, so that part of the limiting block 602 moves out of the interior of the connecting frame 601 and is clamped in the adjustment frame 7, thereby realizing the limitation of the position of the adjustment frame 7 on the top of the bottom plate 2, thereby improving the SF6 and O2 concentration online monitoring components installed on the mounting plate 1 9, the mounting plate 2 10 and the mounting plate 3 11. The stability of the device is ensured to ensure that the operators can perform normal maintenance and repair on them. By providing an inclined surface on the surface of the limit block 602, when the adjustment frame 7 is located at the other end of the limit block 602 and moves to one end, the adjustment frame 7 can just contact with the inclined surface of the limit block 602 first, and then squeeze the inclined surface of the limit block 602, so that the limit block 602 moves toward the inside of the connection frame 601, so that the adjustment frame 7 moves to the position outside the connection frame 601, and there is no need for the operator to pull the limit block 602 inward first, thereby reducing the operation steps, thereby facilitating the movement and limiting of the adjustment frame 7; the elastic force of the spring three 23 itself can form a thrust toward one end on the push block 24, and each block 502 is separated from the inner part of the adjustment frame 7. When the adjusting frame 7 is separated, the spring three 23 can squeeze the push block 24, so that the push block 24 squeezes the connecting block 22 to one end for a distance, so that the card block 502 is misaligned with the adjusting frame 7. At this time, the card block 502 can no longer be inserted into the adjusting frame 7, so that the operator can free up his hands to move the adjusting frame 7. The elastic force of the spring four 25 itself can form a pushing force to the other end on the pressing block 26. When each limit block 602 is separated from the inside of the adjusting frame 7, the spring four 25 can squeeze the pressing block 26, so that the pressing block 26 squeezes the connecting block 22 to the other end for a distance, so that the limit block 602 is misaligned with the adjusting frame 7. At this time, the limit block 602 can no longer be inserted into the adjusting frame 7, so that the operator can free up his hands to move the adjusting frame 7.

[0047] Example 3

[0048] like Figure 2 , Figure 3 and Figure 4 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, a plurality of fixing plates 18 are fixedly installed inside the outer shell 1 at the top of the adjustment frame 7, and a slider 19 is slidably installed inside each fixing plate 18, and the bottom of each slider 19 is fixedly connected to the surface of the adjustment frame 7, and rotating rods 17 are rotatably installed on both sides of the adjustment frame 7, and the outer surface of each rotating rod 17 is transmission-matched with the inner wall of the outer shell 1.

[0049] In this embodiment, the slider 19 is arranged to slide with the fixed plate 18, and the slider 19 is fixedly connected to the adjustment frame 7. When the adjustment frame 7 moves to the inside of the shell 1, the slider 19 can be inserted into the inside of the fixed plate 18, so as to guide and limit the sliding trajectory of the adjustment frame 7 inside the shell 1, thereby reducing the possibility of the adjustment frame 7 bending at both ends or both sides; by the transmission cooperation between the rotating rod 17 and the shell 1, wherein the rotating rod 17 can rotate between the adjustment frame 7 and the shell 1, and the rotating rod 17 can also slide along the surface of the shell 1, when the adjustment frame 7 moves, the rotating rod 17 can slide and rotate along the moving trajectory of the adjustment frame 7, thereby guiding and limiting the sliding trajectory of the adjustment frame 7 to a certain extent, and improving the smooth sliding effect of the adjustment frame 7.

[0050] Example 4

[0051] like Figure 3 , Figure 7 and Figure 8 As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, a card plate 12 is fixedly installed on the top of each mounting plate 19, and a guide member 13 is slidably connected inside each card plate 12, and a plurality of protrusions 21 are attached to the inside of the card plate 12 on both sides of each guide member 13; a card strip 15 is fixedly installed on the bottom of each mounting plate 3 11, and a traction member 16 is slidably connected inside each card strip 15, and a plurality of protrusions 20 are attached to the inside of the card strip 15 on both sides of each traction member 16; a plurality of limit members 14 are fixedly installed on the top and bottom of the mounting plate 2 10.

[0052] In this embodiment, by installing the traction member 16, the guide member 13 and the limit member 14, the placement position of the line or pipeline of the SF6 and O2 concentration online monitoring component can be guided and limited, and the guide member 13 and the traction member 16 can be moved inside the card plate 12 and the card strip 15 respectively according to different actual installation requirements. At the same time, the protrusion 21 and the protrusion 1 20 are made of deformable and resilient rubber material. The protrusion 21 and the protrusion 1 20 can be used to limit the guide member 13 and the traction member 16 respectively, and the position of the line and the pipeline can be adjusted, thereby reducing the possibility of entanglement of the line and the pipeline, ensuring that the SF6 and O2 concentrations can be monitored online normally.

[0053] The working principle of the SF6 and O2 concentration online monitoring device is described in detail below.

[0054] like Figure 1-Figure 11 As shown, when it is necessary to inspect and maintain the components for online monitoring of SF6 and O2 concentrations, the operator can open the protective door 4, then remove each bolt 3, and move the bottom plate 2 to one end to move a part of the bottom plate 2 out of the interior of the housing 1. Then, the operator can pull the pull ring inside each fixed frame 501 inward to move the clamping block 502 to the inside of the fixed frame 501. At this time, the spring three 23 squeezes the push block 24 and pushes the connecting block 22 at the same time, so that the adjustment frame 7 can move a distance to one end. The operator can loosen the pull ring and continue. Continue to move the adjustment frame 7 toward one end, move the adjustment frame 7 to the outside of the connecting frame 601, and at the same time, the spring 2 603 squeezes the limit block 602, so that the limit block 602 is stuck in the inside of the adjustment frame 7, and the adjustment frame 7 is limited, thereby further expanding the distance between the adjustment frame 7 and the outer shell 1, and then expanding the contact space between the operator and the mounting plate 1 9, the mounting plate 2 10 and the mounting plate 3 11, so that the operator can inspect and maintain the components for online monitoring of SF6 and O2 concentrations installed on the mounting plate 1 9, the mounting plate 2 10 and the mounting plate 3 11.

[0055] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
