Description

Technical Field

[0001] The invention relates to the technical field of gas sampling in transformer substations, and in particular to a monitoring sampling device for transformer substations. Background Art

[0002] A substation is a place in the power system where voltage and current are transformed, electric energy is received and distributed. The substation in a power plant is a step-up substation, which boosts the electric energy generated by the generator and feeds it into the high-voltage power grid. The equipment in the substation needs to be monitored around the clock to avoid accidents. In the existing technology, drones are used for large-scale gas sampling operations to collect gas from different places in the substation, and then tested to monitor the status of the substation.

[0003] For example, a substation monitoring sampling system disclosed in a Chinese patent with authorization announcement number CN118168870B mainly fills the storage tube with air, then allows the air to enter the air supply tube, and enters the corresponding elastic top tube through the air guide tube, so that the elastic top tube can successively block the storage space and seal the air in the storage space. When air sampling is performed at other locations, the drone is in a flying state to discharge the air in the unblocked storage space. The exhaust process requires that the air in multiple storage spaces be discharged. When entering another sampling location, it cannot be guaranteed that the previous air is completely discharged. The exhaust hole is small, which will lead to This causes some residual dust and a small amount of air to be retained, which will affect the purity of the air at another sampling location and affect the later detection data. In addition, there are multiple components in the storage space, such as air guides and elastic top pipes. When the air enters the storage space, the air and the dust in the air will adhere to these components. When sampling, different positions will be sampled, which will cause the dust at different positions to adhere to these components. After long-term use, the attached dust will be more messy. The air taken out by the sampling rod will inevitably be accompanied by these dust, which will affect the detection results, resulting in misjudgment and seriously affecting the safety of the substation. Therefore, there is an urgent need for a substation monitoring sampling device that can both classify and store air and clean the air storage space. Summary of the invention

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] Please refer to Figure 1-Figure 12 As shown, the present invention provides a substation monitoring sampling device, including a drone body 1 and a sleeve 2, wherein the sleeve 2 is fixedly arranged on the bottom surface of the drone body 1, and a fixing cylinder 22 is fixedly connected inside the sleeve 2; A plurality of gas storage cylinders 3 are arranged between the sleeve 2 and the fixed cylinder 22, and an air inlet pipe 221 for conveying gas into the gas storage cylinder 3 is fixedly connected to the inner wall of the fixed cylinder 22; The inner wall of the fixed cylinder 22 is rotatably connected to the limiting cylinder 7, and the limiting cylinder 7 is provided with an air guide hole 72 intermittently connected to the air inlet pipe 221; A gas gathering mechanism is rotatably sleeved in the limiting cylinder 7; A rotating mechanism is rotatably arranged in the air storage cylinder 3, and a cleaning mechanism for cleaning the inner wall of the air storage cylinder 3 is slidably arranged on the outer periphery of the rotating mechanism, and a dust vibrating mechanism for knocking and vibrating the inside of the air storage cylinder 3 is arranged on the cleaning mechanism; The top surface of the fixed cylinder 22 is telescopically provided with a power mechanism for driving the rotating mechanism and the limiting cylinder 7 to rotate.

[0019] The drone body 1 is set up so that it is convenient to fly to a high place to collect gas. After completing the collection, the drone body 1 can fly to a designated place and stop, so that the drone body 1 is docked on a docking detection station. The docking detection station belongs to the prior art and is not shown in the accompanying drawings. It is mainly used to introduce the gas collected by the drone body 1 into the docking detection station for detection. In addition, a charging device for charging the drone body 1 is also provided on the docking detection station. It belongs to the prior art and is not shown in the drawings, so as to facilitate charging of the drone body 1 and ensure endurance.

[0020] Among them, a sleeve 2 is arranged on the bottom surface of the drone body 1, a fixed cylinder 22 is fixedly arranged in the sleeve 2, and multiple groups of air storage cylinders 3 are arranged between the sleeve 2 and the fixed cylinder 22. At the same time, an air intake pipe 221 connected with the air storage cylinder 3 is fixedly arranged in the fixed cylinder 22. The air intake pipe 221 is a one-way pipe with a one-way valve arranged inside, which is mainly used to introduce external gas into the air storage cylinder 3. The one-way setting can prevent the gas in the air storage cylinder 3 from being discharged to the outside.

[0021] Among them, a limiting cylinder 7 is rotatably arranged in the fixed cylinder 22, and an air guide hole 72 which is intermittently connected to the air inlet pipe 221 is opened on the limiting cylinder 7, so that the air guide hole 72 can be intermittently connected to the air inlet pipe 221 through the rotation of the limiting cylinder 7, wherein the air inlet pipe 221 is used to connect the air storage cylinder 3 with the outside, so the air inlet pipe 221 and the air storage cylinder 3 are correspondingly arranged, and multiple groups are arranged to ensure that the gas is introduced into different air storage cylinders 3 when gas is collected from different places; with the rotation of the limiting cylinder 7, the air guide hole 72 can be intermittently connected to each group of air inlet pipes 221. When the drone body 1 flies to a place, the limiting cylinder 7 rotates, and at this time the gas gathering mechanism rotates to gather the external gas in the limiting cylinder 7. At this time, with the rotation of the limiting cylinder 7, the air guide hole 72 can be connected to a group of air inlet pipes 221, wherein each group of air inlet pipes 221 There is a gap between them, and there is a certain distance difference, so when the limiting cylinder 7 rotates, the connection between the air inlet pipe 221 and the air guide hole 72 can be guaranteed. When the gas enters the air storage cylinder 3, the limiting cylinder 7 continues to rotate, which can make the limiting cylinder 7 block the air inlet pipe 221 to prevent the gas from entering the air inlet pipe 221. When it is necessary to sample the air in another place, repeating the above operation can store the gas in different places in different air storage cylinders 3 respectively, wherein the external gas only gathers in the limiting cylinder 7, but the bottom end of the limiting cylinder 7 is open, so after the drone body 1 flies to another place, the air in the previous place can be quickly discharged to the outside world to prevent the air in the previous place from gathering in the limiting cylinder 7, and it can also prevent the air from first contacting the internal components of the air storage cylinder 3 and then storing gas through the air storage cylinder 3, thereby ensuring the purity of the gas stored in the air storage cylinder 3.

[0022] Among them, a rotating mechanism is arranged in the air cylinder 3, and a cleaning mechanism is arranged on the periphery of the rotating mechanism for sliding up and down, and a dust vibrating mechanism is arranged, and a power mechanism for intermittently driving the rotating mechanism and the limiting cylinder 7 to rotate is arranged on the top surface of the fixed cylinder 22, so that the cleaning mechanism can be driven to rotate in the air cylinder 3 through the rotation of the rotating mechanism, and the inner wall of the air cylinder 3 is cleaned by the cleaning mechanism, and the cleaning mechanism is arranged to slide up and down. During the sliding process, the cleaning mechanism can vibrate the air cylinder 3 and the cleaning mechanism through the dust vibrating mechanism, so as to shake off the dust on the periphery of the cleaning mechanism and the inner wall of the air cylinder 3 to prevent the dust from being retained in the air cylinder 3.

[0023] Among them, the rotation of the limit cylinder 7 can make the air guide hole 72 intermittently connected with each air inlet pipe 221 separately, and at this time, the outside gas is convenient to enter the gas storage cylinder 3 through the gas gathering mechanism, which can prevent the outside gas from contacting the inner walls of other gas storage cylinders 3 during the gas storage process, and can effectively ensure the purity of each gas storage cylinder 3. A cleaning mechanism and a dust shaking mechanism are rotatably arranged in the gas storage cylinder 3, which can clean the inner wall of the gas storage cylinder 3 during the gas discharge process, avoid more dust adhering to the gas storage cylinder 3 to prevent affecting the purity of the stored gas, and avoid multiple gases from gathering in the gas storage cylinder 3, ensure the sampling purity, prevent the gas detection result from being affected after the gas is extracted, so that accurate detection and judgment can be performed, and misjudgment can be avoided to prevent affecting the safety of the substation, and the purity of the classified stored gas can be achieved and the inner wall of the gas storage cylinder 3 can be cleaned.

[0024] The air storage cylinder 3 is arranged equidistantly along the circumference between the sleeve 2 and the fixed cylinder 22. A fixed plate 31 is fixedly connected to the inner wall of the air storage cylinder 3 near the top, and the fixed plate 31 is rotatably connected to the rotating mechanism through a bearing.

[0025] The gas cylinders 3 are arranged at equal intervals on their circumferences to facilitate classification of the gas cylinders 3 so as to store gas from different places. A fixing plate 31 is provided on the inner wall of the gas cylinder 3 to limit the position of the rotating mechanism.

[0026] The rotating mechanism includes a cleaning rotating rod 4 and a third gear 41 . The outer periphery of the cleaning rotating rod 4 is rotatably connected to the fixing plate 31 via a bearing, and the top end of the cleaning rotating rod 4 is fixedly connected to the third gear 41 .

[0027] The cleaning rotating rod 4 is arranged so as to facilitate the rotation in the air storage cylinder 3 and the air leakage can be avoided by the action of the bearing.

[0028] The cleaning mechanism includes a slider 42, a spring 421 and a cleaning brush 44. An inner groove for the slider 42 to slide up and down is opened in the cleaning rotating rod 4, and a slide groove 43 connected to the inner groove is opened on the outer periphery of the cleaning rotating rod 4. The slider 42 is slidably set in the slide groove 43, and the spring 421 is fixedly set between the slider 42 and the inner groove. The outer periphery of the slider 42 is fixedly connected to the cleaning brush 44, and multiple groups of cleaning brushes 44 are provided.

[0029] The spring 421 is arranged to facilitate the sliding of the slider 42 up and down in the inner groove, and the outer protruding portion of the slider 42 is slidably arranged in the slide groove 43. At the same time, the protruding portion of the slider 42 is fixedly connected to the cleaning brush 44, so that the cleaning brush 44 can slide up and down around the cleaning rotating rod 4, and the cleaning range of the inner wall of the air storage cylinder 3 can be changed.

[0030] The dust vibration mechanism includes a guide rail component and a vibration component. The vibration component includes a vibration disk 311 and a knocking ball 441. The knocking ball 441 is fixedly arranged on the top of the cleaning brush 44. The vibration disk 311 is fixedly arranged on the bottom surface of the fixed plate 31, and the vibration disk 311 is rotatably connected to the cleaning rotating rod 4.

[0031] The guide rail component includes a limiting track 32, a connecting block 442, a connecting rod 5 and a roller 51. The connecting block 442 is fixedly connected between adjacent cleaning brushes 44, wherein two connecting blocks 442 are provided and both are fixedly set between the cleaning brushes 44, and the connecting blocks 442 are symmetrically set, one end of the connecting rod 5 is fixedly connected to the connecting block 442, and the other end is rotatably connected to the roller 51, and the roller 51 is rollingly set on the bottom surface of the limiting track 32, and the limiting track 32 is spirally fixedly connected to the inner wall of the air storage cylinder 3.

[0032] Among them, in order to facilitate understanding of the above-described connecting block 442 fixedly set between the cleaning brushes 44, the following description is made: the cleaning brushes 44 are provided with multiple groups, and the multiple groups are divided into four, respectively recorded as brush one, brush two, brush three and brush four, wherein brush two and brush four are respectively located on both sides of brush one, and brush two and brush three are symmetrically arranged, and the two connecting blocks 442 are respectively recorded as block one and block two, and the connecting block 442 is fixedly set between the cleaning brushes 44, which means that block one is fixedly connected between brush one and brush two, and block two is fixedly connected between brush three and brush four.

[0033] By setting the limiting track 32, as Fig.10 As shown, the starting position and the ending position of the limiting track 32 are on the same horizontal plane. The state of the limiting track 32 and the starting position and the ending position of the limiting track can be specifically seen in the figure, and the roller 51 is rotatably set on the bottom surface of the limiting track 32, so the roller 51 is instantly released and moves upward after sliding over the bottom position of the limiting track 32, so that the roller 51 slides again on the bottom surface of the starting position of the limiting track 32.

[0034] The cleaning brush 44 can drive the cleaning brush 44 to rotate around the inner wall of the air storage cylinder 3 during the rotation process, so that the cleaning brush 44 can clean the dust on the inner wall of the air storage cylinder 3 and sweep the dust off. The cleaning brush 44 can drive the connecting block 442 to rotate during the rotation process, and the connecting block 442 drives the connecting rod 5 to rotate, and the connecting rod 5 drives the roller 51 to rotate, so that the roller 51 rolls along the bottom surface of the limiting track 32. Through the spiral arrangement of the limiting track 32, the roller 51 rolls along the limiting track 32 while the roller 51 moves downward. The roller 51 drives the connecting rod 5 and the connecting block 442 to move downward, and the connecting block 442 drives the cleaning brush 44 to move downward. The cleaning brush 44 drives the slider 42 to move downward, so that the slider 42 can pull and compress the spring 421. When the roller 51 rolls to the lowest surface of the limiting track 32, the pulling and compression of the spring 421 reaches the maximum. Continuous rotation can make the roller 51 slide out from the lowest surface of the limiting track 32. Since the starting position and the end position of the limiting track 32 are on the same horizontal plane, the spring 421 will instantly restore the elastic force after sliding out from the lowest end of the limiting track 32, wherein the lowest end of the limiting track 32 is the end position of the limiting track 32, so that the slider 42 has a process of sliding upward instantly, thereby making the slider 42 drive the cleaning brush 44 to slide upward, and the cleaning brush 44 drives the knocking ball 441 to move upward, so that the knocking ball 441 knocks and vibrates the vibration disk 311, and the vibration of the vibration disk 311 causes the fixing plate 31 and the gas cylinder 3 to vibrate, and at the same time as the knocking and vibration, the cleaning brush 44 can also be vibrated, so that the dust attached to the outer periphery of the cleaning brush 44 and the inner wall of the gas cylinder 3 can be shaken off, and the dust can be discharged at the same time when the gas in the gas cylinder 3 is discharged, so as to avoid being trapped in the gas cylinder 3 to prevent it from affecting the reuse.

[0035] The bottom surface of the sleeve 2 is provided with a plug hole 23 corresponding to the air storage cylinder 3, the inner wall of the plug hole 23 is fixedly connected with an exhaust pipe 21, the top end of the exhaust pipe 21 is connected with the air storage cylinder 3, and a valve is arranged in the exhaust pipe 21.

[0036] Through the setting of the exhaust pipe 21, a valve is provided in the exhaust pipe 21. When the gas sampling is completed and the vehicle stops on the docking detection platform, the plug corresponding to the exhaust pipe 21 on the docking detection platform is plugged into the exhaust pipe 21. When the plug on the docking detection platform is inserted into the exhaust pipe 21, the valve will open. This method belongs to the prior art and will not be described in detail here. It is not drawn in the accompanying drawings. Therefore, after docking, it is convenient for the gas in the gas storage cylinder 3 to flow into the docking detection platform so as to detect the gas.

[0037] The gas gathering mechanism includes a first gear 12, a second gear 13, a rotating rod 131 and a fan blade 132. The diameter of the first gear 12 is larger than that of the second gear 13. A sleeve groove 11 is provided on the bottom surface of the drone body 1 corresponding to the upper side of the limiting cylinder 7. The first gear 12 and the second gear 13 are both rotatably arranged in the sleeve groove 11. The first gear 12 and the second gear 13 are meshingly connected. The bottom end of the second gear 13 is fixedly connected to the rotating rod 131. The bottom end of the rotating rod 131 is inserted into the limiting cylinder 7, and the outer periphery of the bottom end of the rotating rod 131 is fixedly connected to the fan blade 132. The outer periphery of the first gear 12 is meshingly connected with a first gear sleeve 71. The first gear sleeve 71 is rotatably arranged in the sleeve groove 11, and the bottom end of the first gear sleeve 71 is fixedly connected to the limiting cylinder 7 through a support rod.

[0038] The rotation of the first gear sleeve 71 can drive the first gear 12 to rotate, and the first gear 12 drives the second gear 13 to rotate, wherein the diameter of the first gear 12 is greater than the diameter of the second gear 13, and the diameter of the first gear 12 is five times the diameter of the second gear 13, so when the first gear 12 is in a rotating state, the number of rotations of the second gear 13 can be guaranteed, so that the number of rotations of the second gear 13 increases, so when the second gear 13 is in a rotating state, it drives the rotating rod 131 and the fan blades 132 to rotate multiple times, and can inhale through the fan blades 132 during the rotation process, and gather the external gas in the limit tube 7, so that the gas can enter the gas storage cylinder 3 through the air guide hole 72.

[0039] A support guide rod is fixedly connected to the top surface of the air storage cylinder 3 , a second gear sleeve 8 is provided on the top end of the support guide rod, and the outer periphery of the second gear sleeve 8 is meshedly connected with the third gear 41 .

[0040] The power mechanism is arranged between the first gear sleeve 71 and the second gear sleeve 8, and the power mechanism includes an electric telescopic rod 6, a rotating motor 61 and a fourth gear 611. A groove 222 for fixing the electric telescopic rod 6 is provided on the top surface of the fixed cylinder 22. The top of the electric telescopic rod 6 is fixedly connected to the rotating motor 61, and the power output end of the rotating motor 61 is fixedly connected to the fourth gear 611. The fourth gear 611 slides up and down and is intermittently meshed with the first gear sleeve 71 and the second gear sleeve 8. The second gear sleeve 8 is located below the first gear sleeve 71.

[0041] By setting the second gear sleeve 8, the second gear sleeve 8 is rotatably set on the bottom surface of the drone body 1, and the second gear sleeve 8 is located below the first gear sleeve 71. The height of the fourth gear 611 can be adjusted by starting the electric telescopic rod 6, so that the fourth gear 611 is meshed and connected with the first gear sleeve 71. Among them, at the moment when the fourth gear 611 is meshed with the outer periphery of the first gear sleeve 71, the fourth gear 611 is disengaged from the meshing with the inner wall of the second gear sleeve 8. At this time, the rotation of the rotating motor 61 can drive the first gear sleeve 71 to rotate slowly, and the first gear sleeve 71 drives the first gear 12 to rotate. At this time, the rotation of the fan blades 132 can be used to gather gas, so that the gas can be merged into the gas storage cylinder 3. After the gas sampling is completed, since the rotation speed of the rotating motor 61 per unit time is the same, the rotating motor 61 drives the fourth gear 611 to rotate. The number of circles is fixed, so when the fourth gear 611 moves downward after the gas collection is completed, it can be ensured that the fourth gear 611 falls into the second gear sleeve 8 and meshes with the second gear sleeve 8, and the moment the fourth gear 611 meshes with the second gear sleeve 8, the fourth gear 611 is disengaged from the meshing state with the first gear sleeve 71, wherein the same rotation speed of the rotating motor 61 per unit time is the prior art and will not be elaborated on here; when the fourth gear 611 meshes with the second gear sleeve 8, the fourth gear 611 can drive the second gear sleeve 8 to rotate, the second gear sleeve 8 drives the third gear 41 to rotate, and the third gear 41 drives the cleaning rotating rod 4 to rotate, so the cleaning brush 44 can be used to complete the cleaning of the inner wall of the gas storage cylinder 3, wherein the process of cleaning the inner wall of the gas storage cylinder 3 is the process of introducing the gas into the docking detection bench after the gas collection is completed.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
