Description

Technical Field

[0001] The present invention relates to the technical field of monitoring sensors, and in particular to an SF6 composite integrated on-line monitoring sensor. Background Art

[0002] During the operation of a substation, SF6 is usually used for insulation and arc extinguishing. However, during operation, once a leakage occurs, it is easy to cause the internal gas pressure of the equipment to decrease and the insulation performance to decline, which may trigger internal discharges, short circuits and other faults in the equipment, resulting in safety accidents.

[0003] However, due to the relatively large specific gravity of SF6, it will sink when a leakage occurs. The installation position of traditional monitoring sensors is fixed, and the leakage position cannot be accurately monitored during monitoring, which affects the accuracy of fault alarms and has an adverse impact on fault troubleshooting and detection accuracy. For this reason, we propose an SF6 composite integrated on-line monitoring sensor, which monitors the gas leakage point by continuously changing the position, improves the monitoring effect, and facilitates fault troubleshooting. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose an SF6 composite integrated on-line monitoring sensor.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: An SF6 composite integrated on-line monitoring sensor, comprising: A C-shaped bracket, on which two sets of reciprocating lead screws arranged in parallel are rotatably provided, and a servo motor for controlling the rotation of one of the reciprocating lead screws is provided at the top of the C-shaped bracket; A monitoring component, the monitoring component includes an air extraction housing, an air extraction component and a sensor for detection are provided inside the air extraction housing, a filtering component is rotatably provided at the lower part of the air extraction housing for filtering the inhaled air to reduce the adverse impact of impurities in the air on the monitoring process, a knocking component is installed on the side of the air extraction housing, and a top contact rod penetrates through the center of the air extraction housing, and the top contact rod is linked with the filtering component for cooperating with the knocking component to realize the self-cleaning function of the filtering component; The air extraction component includes a fan blade component arranged outside the top contact rod, as well as a driving motor and a driving gear; A guide block is fixedly installed on one side of the air extraction housing, and the guide block is in threaded cooperation with the reciprocating lead screw controlled by the servo motor, and a guide groove for the sliding of the guide block is vertically opened on the side surface of the C-shaped bracket, which facilitates the vertical movement of the monitoring component; A fixed ring is fixedly installed on the side of the air extraction housing. A driven meshing component is rotatably arranged inside the fixed ring. The driven meshing component is threadedly sleeved on the outside of another set of reciprocating lead screws, and the lower part of the outside of the driven meshing component is meshed with the filtering component. Thus, during the overall movement of the monitoring component, the driven meshing component is driven to move up and down, and rotates under the action of torque, realizing the rotation of the filtering component, providing a rotational power basis for the self-cleaning function; The control component is fixedly installed at the top of the C-shaped bracket, is electrically connected to the servo motor, controls the start and stop of the servo motor, and is provided with an alarm module for positioning and alarming during the detection process.

[0006] As a preferred technical solution of the present application, a fixing plate is fixedly installed on the upper part inside the air extraction housing. A sensor and a driving motor are installed at the bottom end of the fixing plate. The output shaft of the driving motor faces downward and is coaxially connected with a driving gear, and the driving gear is meshed with the fan blade component; The fan blade component includes a penetrating sleeve rotatably sleeved on the outside of the top contact rod.

Three fixed blades are evenly arranged on the lower part of the outside of the rotating collar. A meshing tooth is arranged on the upper part of the outside of the rotating collar and is meshed with the driving gear. Thus, under the power output action of the driving motor, the forward and reverse rotation of the fan blade component is controlled, so as to realize air extraction and air blowing during the monitoring process, facilitating the sensor to perform component detection; A plurality of ventilation holes are provided at the top of the air extraction housing to facilitate air pressure balance during the working process.

[0007] As a preferred technical solution of the present application, contact plates are provided at both the top end and the bottom end of the top contact rod. Trigger blocks are installed on the contact plates, and control switches are provided at the positions corresponding to the trigger blocks at the top of the air extraction housing. The control switch at the top controls the air blowing of the air extraction component, and the control switch at the bottom controls the air blowing of the air extraction component. Thus, after the overall component rises to the top and then descends, air is blown to clean the dust on the filtering component. When the monitoring component moves to the bottom of the C-shaped bracket and contacts the bottom, with the help of the control switch, the working mode of the air extraction component is adjusted, and then it rises again. The air extraction component performs air suction to achieve the purpose of real-time monitoring.

[0008] As a preferred technical solution of the present application, a toothed ring is installed on the lower part of the outside of the top contact rod, and a plurality of clamping components are installed inside the air extraction housing. The clamping component includes a telescopic rod, and one end of the telescopic rod is fixedly connected with a toothed rack meshed with the toothed ring, which is used to ensure that the position of the contact plate and the top contact rod on the monitoring component is clamped after being touched.

The striking steel ball is used to trigger the striking component to achieve periodic collision between the striking component and the filter component, thereby ensuring that the bottom of the filter component is effectively struck periodically to avoid dust accumulation; One end of the protruding rod located inside the rotating gear ring is connected to a deflection rod, and one end of the deflection rod is hinged with the same set of connecting rings. A fixed shaft sleeve is passed through the inner side of the connecting ring, and the fixed shaft sleeve is fixedly installed on the outer side of the top touch rod. When the top touch rod touches the top or bottom end of the C-shaped bracket during the overall movement of the monitoring component, the top touch rod is displaced, which effectively drives the deflection rod to deflect, thereby controlling the extension of the protruding rod and realizing the collision and striking with the knocking component.

[0010] As a preferred technical solution of the present application, a filter is provided at the inner lower part of the rotating gear ring for isolating the rotating gear ring during actual use to prevent dust and impurities from affecting the actual monitoring process.

[0012] As a preferred technical solution of the present application, the driven engaging assembly includes a threaded sleeve threadedly mounted on the outside of a reciprocating screw, the threaded sleeve is mounted on the outside of a fixed ring, and an engaging toothed ring engaging with a filter assembly is provided on the lower outer portion of the threaded sleeve. When the monitoring assembly moves up and down and drives the driven engaging assembly to move up and down, the driven engaging assembly is rotated under the action of the torque of the threaded sleeve and the reciprocating screw, thereby driving the filter assembly to rotate, thereby providing assistance for the self-cleaning effect of the filter assembly.

[0013] The beneficial effects of the present invention are: The SF6 is detected by the up-and-down moving monitoring component in conjunction with the internal exhaust component and the sensor, and the position start and stop of the monitoring component is effectively controlled by the control component, so that the leakage height of SF6 can be effectively located, which is convenient for the actual monitoring process and can provide convenience for subsequent troubleshooting; By setting a position-changeable top contact rod, a cooperating control switch, and an air extraction component, the overall monitoring component can switch between air extraction and air blowing when the motion state changes. In cooperation with the linked filtration component and knocking component, the effective self-cleaning of the filter screen at the bottom of the filtration component is achieved, facilitating the cleaning of the overall device during actual use and avoiding the problem of dust accumulation affecting the monitoring efficiency during the monitoring process.

[0014] In summary, during actual use, this application can effectively monitor SF6, monitor and locate the leakage point. By setting multiple groups of devices during actual use, it can more accurately facilitate the staff to troubleshoot faults. It can also effectively achieve the purpose of self-cleaning during actual use, ensuring a long-term effective monitoring effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Refer to Figures 1-10 , an SF6 composite integrated online monitoring sensor, including: A C-shaped bracket 1, on which two groups of parallel reciprocating lead screws 3 are rotatably arranged, and a servo motor 2 for controlling the rotation of one group of reciprocating lead screws 3 is arranged at the top of the C-shaped bracket 1; A monitoring component 4, the monitoring component 4 includes an air extraction housing 41, an air extraction component and a sensor 411 for monitoring are arranged inside the air extraction housing 41, a filter component 43 is rotatably arranged at the lower part of the air extraction housing 41, which is used for filtering the inhaled air to reduce the adverse impact of impurities in the air on the monitoring process, a knocking component 44 is installed on the side of the air extraction housing 41, and a thrust contact rod 49 penetrates through the center of the air extraction housing 41, and the thrust contact rod 49 is linked with the filter component 43, which is used to cooperate with the knocking component 44 to realize the self-cleaning function of the filter component 43; The air extraction component includes a fan blade component 47 arranged outside the thrust contact rod 49, as well as a driving motor 412 and a driving gear 413; A guide block 6 is fixedly installed on one side of the air extraction housing 41, the guide block 6 is in threaded cooperation with the reciprocating lead screw 3 controlled by the servo motor 2, and a guide groove for the sliding of the guide block 6 is vertically opened on the side of the C-shaped bracket 1, which is convenient to realize the vertical movement of the monitoring component 4; A fixing ring 42 is fixedly installed on the side of the air extraction housing 41. A driven meshing assembly 5 is rotatably arranged inside the fixing ring 42. The driven meshing assembly 5 is threadedly sleeved on the outside of another reciprocating lead screw 3. The lower part of the outside of the driven meshing assembly 5 is meshed with the filtering assembly 43. Thus, during the overall movement of the monitoring assembly 4, the driven meshing assembly 5 is driven to move up and down, and rotates under the action of torque, realizing the rotation of the filtering assembly 43, providing a rotational power basis for the self-cleaning function; The control assembly 7 is fixedly installed at the top of the C-shaped bracket 1, is electrically connected to the servo motor 2, controls the start and stop of the servo motor 2, and is provided with an alarm module for positioning and alarming during the detection process.

[0019] Refer to Figures 3-4 and Figure 8 An upper inner part of the air extraction housing 41 is fixedly installed with a fixing plate 46. A sensor 411 and a driving motor 412 are installed at the bottom end of the fixing plate 46. The output shaft of the driving motor 412 faces downward and is coaxially connected with a driving gear 413. The driving gear 413 is meshed with the fan blade assembly 47; The fan blade assembly 47 includes a penetrating sleeve 471 rotatably sleeved on the outside of the top contact rod 49. The penetrating sleeve 471 is fixedly connected to the inner wall of the air extraction housing 41 through a connecting rod. A rotating collar 472 is rotatably sleeved on the outside of the penetrating sleeve 471. Three fixed blades 473 are evenly arranged on the lower part of the outside of the rotating collar 472. Meshing teeth are arranged on the upper part of the outside of the rotating collar 472, which is meshed with the driving gear 413. Thus, under the power output action of the driving motor 412, the forward and reverse rotation of the fan blade assembly 47 is controlled, so as to realize air extraction and air blowing during the detection process, facilitating the component detection by the sensor 411; The top of the air extraction housing 41 is provided with a number of ventilation holes to facilitate air pressure balance during the working process.

[0020] Both the top end and the bottom end of the top contact rod 49 are provided with a contact plate 45. A trigger block is installed on the contact plate 45. A control switch 414 is provided at the position corresponding to the trigger block at the top of the air extraction housing 41. The control switch 414 located at the top controls the air blowing of the air extraction assembly, and the control switch 414 located at the bottom controls the air blowing of the air extraction assembly. Thus, after the overall assembly rises to the top and descends, air blowing is carried out to clean the dust of the filtering assembly 43. When the monitoring assembly 4 moves to the bottom of the C-shaped bracket 1 as a whole and contacts the bottom, with the help of the control switch 414, the working mode of the air extraction assembly is adjusted, and then it rises again. The air extraction assembly sucks air to achieve the purpose of real-time monitoring.

[0021] A gear tooth ring 410 is installed at the lower part of the outer side of the top contact rod 49, and several groups of clamping components 48 are installed inside the air extraction housing 41. The clamping component 48 includes a telescopic rod 481, and one end of the telescopic rod 481 is fixedly connected with a gear rack 482 which is meshed with the gear tooth ring 410, so as to ensure that the position of the contact plate 45 and the top contact rod 49 on the monitoring component 4 is clamped after being touched.

[0022] Refer to Figures 5-6 , the filtering component 43 includes a rotating gear ring 431. The top end of the rotating gear ring 431 is rotatably arranged at the bottom end of the air extraction housing 41 in an internally suspended manner, and external meshing teeth are arranged on the outer side of the bottom end of the rotating gear ring 431; A plurality of groups of protruding rods 432 penetrate through the bottom end of the rotating gear ring 431. One end of the protruding rod 432 penetrates through the rotating gear ring 431 and extends to the outside, and a striking steel ball 437 is connected to the other end. The striking steel ball 437 is used to trigger the knocking component 44, so as to realize the periodic collision between the knocking component 44 and the filtering component 43, ensure that the bottom of the filtering component 43 is effectively and periodically struck, and avoid dust accumulation; One end of the protruding rod 432 located inside the rotating gear ring 431 is connected with a deflecting rod 435, and one end of the deflecting rod 435 is hinged with the same set of connecting collar 434. A fixed shaft sleeve 433 is penetrated through the inner side of the connecting collar 434, and the fixed shaft sleeve 433 is fixedly installed on the outer side of the top contact rod 49. Therefore, when the top contact rod 49 moves integrally with the monitoring component 4 and touches the top end or the bottom end of the C-shaped bracket 1, the displacement of the top contact rod 49 is realized, effectively driving the deflection of the deflecting rod 435, and then controlling the extending situation of the protruding rod 432 to realize the collision strike with the knocking component 44.

[0023] A filter screen 436 is arranged at the lower part of the inner side of the rotating gear ring 431, which is used for isolation during actual use to avoid the influence of dust impurities, etc. on the actual monitoring process.

[0024] Refer to Figure 7 , the knocking component 44 includes a fixed frame 441. A top rod 442 penetrates through the lower part of the fixed frame 441. One end of the top rod 442 is connected with a striking plate 444 which abuts against the lower part of the outer side of the rotating gear ring 431. The striking plate 444 is arc-shaped to reduce the phenomenon of movement interference during actual operation; A spring 443 is sleeved on the outer side of the top rod 442 to ensure that the striking plate 444 can be effectively abutted, so as to realize the periodic striking of the striking plate 444 on the filtering component 43 to remove dust under the cooperation of the filtering component 43 and the knocking component 44.

[0025] Refer to Figure 10, the driven meshing assembly 5 includes a threaded bushing 51 sleeved on the outer side of the reciprocating lead screw 3. The threaded bushing 51 is sleeved on the outer side of the fixed ring 42. A meshing tooth ring 52 meshing with the filtering assembly 43 is provided at the lower part of the outer side of the threaded bushing 51. Thus, when the monitoring assembly 4 moves up and down and drives the driven meshing assembly 5 to move up and down, the driven meshing assembly 5 rotates under the torque action of the threaded bushing 51 and the reciprocating lead screw 3, and then drives the rotation of the filtering assembly 43, providing assistance for the self-cleaning function of the filtering assembly 43.

[0026] Working process: First, during the actual work, the servo motor 2 starts to drive the reciprocating lead screw 3 to rotate, and then drives the guide block 6 and the monitoring assembly 4 to rotate in the vertical direction. During this process, the air extraction assembly inside the monitoring assembly 4 extracts air, monitors the components in the air, and judges whether SF6 is contained at different heights through the sensor 411 to avoid the phenomenon of SF6 leakage. When SF6 components are detected at a certain height, an alarm will be sent through the control assembly 7, and the servo motor 2 will be stopped to achieve the positioning of the detection height, effectively facilitating the detection of the leakage point and achieving efficient positioning. During a detection process, when the monitoring assembly 4 rises to the top, the control switch 414 located at the top is triggered, causing the air extraction assembly to perform a blowing operation. During this process, the top contact rod 49 is touched and moves downward, so that the position of the striking steel ball 437 slides downward, driving the deflection rod 435 to deflect and pushing against the protruding rod 432. At this time, the position of the striking steel ball 437 protrudes outward, and then it can touch the knocking assembly 44. During the movement of the overall monitoring assembly 4, the driven meshing assembly 5 is forced to move up and down under the action of the fixed ring 42 and deflects under the torque action, so that the filtering assembly 43 meshing with it rotates. As a result, the filtering assembly 43 drives the protruding striking steel ball 437 to collide with the striking plate 444 on the knocking assembly 44 periodically, so that the striking plate 444 can strike the outer side of the filtering assembly 43 periodically, preventing the dust accumulated on the filter screen 436 from being knocked during the air extraction process. Cooperating with the blowing operation of the air extraction assembly, the effective removal of dust is achieved to achieve the self-cleaning purpose. When the overall monitoring assembly 4 moves to the bottom again, the top contact rod 49 moves upward, the striking steel ball 437 retracts, and the control switch 414 located at the bottom is triggered, and the air extraction assembly extracts air, and so on for cyclic operation, thus effectively realizing the monitoring process.
