Description

Technical Field

[0001] The utility model relates to the technical field of SF6 gas leakage detection, in particular to a mobile SF6 gas leakage self-priming detection and early warning device. Background Art

[0002] SF6 is an artificial gas compound formed by a sulfur (S) atom and six fluorine (F) atoms bonded together by covalent bonds. SF6 is colorless, odorless, and non-toxic at room temperature. Its density is about 5 times that of air. It does not react with metals, plastics, or insulating materials at room temperature and is non-corrosive. It decomposes into sulfur fluorides (such as SF4, S2F10) and hydrogen fluoride (HF) under electric arc or high temperature (>200°C), which are highly toxic and corrosive.

[0003] In order to detect SF6 leakage now, concentration sensors are mostly set up for detection. Due to the high density of SF6, after leakage, SF6 will gather at the bottom of the space. In the early stage of detection, SF6 will drop to the detection point, and the device can capture and detect its data. However, as time goes by, SF6 continues to drop and gathers below the detection point. As the concentration increases, the detection point cannot accurately capture it, resulting in inaccurate detection. Utility Model Content

[0004] The purpose of the utility model is to provide a mobile SF6 gas leakage self-priming detection and early warning device to solve the problem in the above-mentioned background technology that SF6 has a large density and will undergo dynamic sedimentation, and during this process, a single detection space will have inaccurate detection.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A mobile SF6 gas leakage self-absorption detection and early warning device comprises: a mobile platform, and also comprises: a vehicle body fixedly mounted on the top of the mobile platform, a transmission antenna structure fixedly mounted on one end of the top of the vehicle body for transmitting vehicle signals, an identification structure fixedly mounted on one side of the vehicle body for real-time identification of the surrounding environment during the operation of the vehicle, for planning the walking route of the vehicle during the detection process, and an absorption early warning mechanism for gas absorption detection installed inside the vehicle body;

[0007] The absorption warning mechanism is composed of a cyclic lifting structure and a gas absorption detection structure. The cyclic lifting structure includes a base frame fixedly installed at the bottom end of the vehicle body, a mounting frame fixedly installed on the top of the base frame, a plurality of cross bars equidistantly rotatably connected to the top of the mounting frame, one end of each of the cross bars passes through the side wall of the mounting frame and is fixedly installed with a first bevel gear, a plurality of mounting seats are equidistantly fixedly installed on one side of the mounting frame, two synchronous belt structures are installed below the plurality of mounting seats, a plurality of second bevel gears are rotatably connected to the top of the plurality of mounting seats, and one end of the second bevel gear passes through the side wall of the mounting seat and is matched with the synchronous belt structure, a driving motor is fixedly installed on one side of the mounting frame, and the output end of the driving motor is matched with the two synchronous belt structures.

[0008] By adopting the above technical solution, when maintaining or decommissioning power equipment, SF6 gas leakage may occur due to sealing reasons. Under the action of electric arc or electric spark, SF6 gas will decompose to produce sulfur fluoride and other toxic substances. These decomposition products are irritating and corrosive, and may be harmful to the respiratory system and skin. Therefore, it is necessary to conduct periodic inspections to avoid the above situation. Due to the high density of SF6 gas, SF6 gas will gather at the bottom of the space after leakage. This results in SF6 gas being close to the ground during the detection process after leakage, which will cause the absorption of ground debris during the leakage detection process, affecting the accuracy of SF6 gas detection. Therefore, the device is provided with an absorption warning mechanism for quickly extracting and detecting the concentration of SF6 gas. When the preset concentration threshold is reached, the signal is transmitted to the staff, who will handle it in a timely manner.

[0009] A further improvement of the technical solution of the utility model is that the two synchronous belt structures are diagonally arranged, the two synchronous belt structures are linearly arranged, and the head and tail are coaxially connected.

[0010] By adopting the above technical solution, the synchronous belt structure connected coaxially at the head and tail can quickly drive the second bevel gear to rotate, and the diagonally arranged synchronous belt structure can further improve the installation fit between the two synchronous belt structures and the installation fit of the mechanical structure, thereby improving the smoothness of the device during operation, thereby better detecting the concentration of SF6 gas.

[0011] A further improvement of the technical solution of the utility model is that the circulating lifting structure also includes a number of connecting columns equidistantly fixedly installed on the inner top of the vehicle body, the bottom ends of the several connecting columns are respectively fixedly connected to the upper surfaces of the several mounting plates, connecting pipes are provided under the mounting plates, connecting ear plates are symmetrically fixedly installed on both sides of the connecting pipes, the bottom ends of the several connecting columns pass through the mounting plates and the connecting ear plates and are slidably connected to each other, the bottom ends of the several connecting columns are sleeved with auxiliary springs, and the auxiliary springs are arranged between the mounting plates and the connecting ear plates, cams are fixedly installed at both ends of the several cross bars, and the cams are squeezed and fitted with the connecting pipes.

[0012] By adopting the above technical solution, when the device moves, the driving motor drives the synchronous belt structure to rotate synchronously, and then drives the first bevel gear and the second bevel gear to rotate. As the two rotate, the cross bar can be driven to drive the cam to perform cyclic circular motion. As the cam moves periodically, the cam will squeeze the connecting pipe. As the cam squeezes the connecting pipe, the connecting pipe will periodically move upward. As the connecting pipe moves, the connecting pipe will drive the gas absorption detection structures distributed at both ends to rise and fall periodically, thereby increasing the detection space of the gas absorption detection structure. Further, in conjunction with the physical properties of SF6 gas, the gas in a larger space can be detected quickly and evenly, avoiding the problem of insufficient detection accuracy due to the dynamic sedimentation of SF6 gas and the single space detection of the device.

[0013] A further improvement of the technical solution of the utility model is that a matching sleeve ring which is pressed and matched with the cam is symmetrically arranged on the connecting pipe.

[0014] By adopting the above technical solution, the matching rings at both ends of the connecting pipe can improve the wear resistance of the connecting pipe, avoid long-term extrusion and friction of the cam causing wear on the outer wall of the connecting pipe, thereby reducing the transmission coordination and accuracy between the parts of the device. The setting of the matching rings can improve the smoothness of the device during operation and reduce the failure rate of the equipment.

[0015] A further improvement of the technical solution of the utility model is that the gas absorption detection structure includes a plurality of vertical tubes respectively fixedly installed at both ends of the connecting pipes, a connecting seat is fixedly installed at the bottom end of the vertical tubes, a guide tube is fixedly installed equidistantly inside the connecting seat, a guide seat is fixedly installed at one end of the guide tube away from the connecting seat, a shielding net is fixedly installed on one side of the guide seat, the middle parts of the plurality of connecting pipes are fixedly connected through a conveying hose, the bottom end of the conveying hose is fixedly connected to the input end of the gas filtering structure, and the gas filtering structure is fixedly installed at the bottom end of the interior of the vehicle body, the output end of the gas filtering structure is fixedly connected to the input end of the air pump through the conveying pipe, the output end of the air pump is fixedly connected to the input end of the SF6 gas detection device, the output end of the SF6 gas detection device is fixedly installed with an outlet pipe, and the end of the outlet pipe away from the SF6 gas detection device is fixedly connected to the side wall of the vehicle body.

[0016] With the above technical solution, during the movement of the device, the connecting pipe is driven by the cam to perform periodic reciprocating motion. As the connecting pipe rises and falls, the vertical pipe and the connecting seat cooperate to rise and fall, and a number of guide pipes for extracting air are circumferentially installed on the connecting seat. In order to prevent debris on the ground from entering the interior of the device during the air extraction process and affecting the detection accuracy of the device, a guide seat and a shielding net are provided at the end of the guide pipe, which can further increase the contact area with the air during air extraction, and can also isolate the debris on the ground to prevent the debris from entering the interior of the device. After the guide pipe draws the external air into the interior of the device, the air is transported to the gas filtration structure by the delivery hose, and the air is further filtered by the gas filtration structure to filter fine substances such as dust in the air. After that, it enters the SF6 gas detection device for concentration detection. In this process, in order to increase the intensity of the gas during the extraction process, an air pump is provided on the gas absorption detection structure, which can continuously provide a certain intensity of suction force to better extract the air, so that the air pump can detect the concentration.

[0017] A further improvement of the technical solution of the utility model is that a detachable filter screen structure is installed inside the gas filter structure.

[0018] By adopting the above technical solution, the detachable filter mesh structure can further improve the operability of the device, so that the gas filtering structure can maintain a high filtering efficiency for a long time, thereby keeping the air entering the air pump at a high level of cleanliness, avoiding long-term operation, which leads to dust accumulation, reduces the detection sensitivity of the air pump, and makes detection inconvenient.

[0019] A further improvement of the technical solution of the utility model is that matching grooves for slidingly matching with the connecting pipe are equidistantly provided on the side wall of the vehicle body to limit the lifting and lowering of the connecting pipe.

[0020] By adopting the above technical solution, the matching grooves on both sides of the vehicle body can limit the running trajectory of the connecting pipe, further improve the accuracy of the connecting pipe during the lifting process, increase the matching accuracy between components, and thus improve the operating stability of the device.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model can quickly and periodically swing up and down during the movement of the device through the setting of the absorption warning mechanism, thereby increasing the concentration detection space range of the device, avoiding the situation that the detection point is relatively single, resulting in inaccurate SF6 concentration detection data. In addition, due to the large density of SF6, after leakage, SF6 will gather at the bottom of the space, and the device will appear in the early stage of detection, SF6 will drop to the detection point, and as time goes by, SF6 will continue to drop and gather below the detection point. While the concentration increases, the detection point cannot accurately capture it, resulting in inaccurate detection. The setting of the absorption warning mechanism can avoid the above problems, and the up and down swing can increase the detection range, better meet the characteristics of SF6 gas itself to detect the concentration, and further improve the detection accuracy during leakage.

[0023] 2. The gas absorption detection structure of the utility model further improves the concentration detection by inhaling air at multiple points, and increases the capture points for air extraction, thereby increasing the detection range of SF6 gas, thereby improving the detection accuracy of the device. In addition, a two-layer filtering mechanism is provided in the gas absorption detection structure to filter debris and dust on the ground to prevent them from entering the interior of the device, causing the detection sensitivity of the SF6 gas detection device to decrease, thereby reducing the detection accuracy of the concentration.

DETAILED DESCRIPTION

[0034] The utility model is further described in detail below in conjunction with the embodiments.

[0035] Example 1

[0036] like Figure 1 and Figure 2 As shown, the utility model provides a mobile SF6 gas leakage self-absorption detection and early warning device, comprising: a mobile platform 1, and also comprising: a vehicle body 2 fixedly mounted on the top of the mobile platform 1, a transmission antenna structure 3 fixedly mounted on one end of the top of the vehicle body 2, used for transmitting vehicle signals, an identification structure 4 fixedly mounted on one side of the vehicle body 2 for real-time identification of the surrounding environment during the operation of the vehicle, used for planning the walking route of the vehicle during the detection process, and an absorption early warning mechanism 5 for gas absorption detection is installed inside the vehicle body 2;

[0037] The absorption warning mechanism 5 is composed of a cyclic lifting structure and a gas absorption detection structure. The cyclic lifting structure includes a base frame 6 fixedly installed at the bottom end of the vehicle body 2. A mounting frame 7 is fixedly installed on the top of the base frame 6. A plurality of cross bars 8 are equidistantly rotatably connected to the top of the mounting frame 7. One end of each of the cross bars 8 passes through the side wall of the mounting frame 7 and is fixedly installed with a first bevel gear 9. A plurality of mounting seats 10 are equidistantly fixedly installed on one side of the mounting frame 7. Two synchronous belt structures 11 are installed below the plurality of mounting seats 10. A plurality of second bevel gears 12 are rotatably connected to the top of the plurality of mounting seats 10, and one end of the second bevel gear 12 passes through the side wall of the mounting seat 10 and is matched with the synchronous belt structure 11. A drive motor 13 is fixedly installed on one side of the mounting frame 7, and the output end of the drive motor 13 is matched with the two synchronous belt structures 11.

[0038] In this embodiment, when maintaining or decommissioning power equipment, SF6 gas leaks due to sealing reasons. Under the action of electric arc or electric spark, SF6 gas will decompose to produce sulfur fluoride and other toxic substances. These decomposition products are irritating and corrosive, and may be harmful to the respiratory system and skin. Therefore, it is necessary to perform periodic inspections to avoid the above situation. Since the density of SF6 gas is relatively high, SF6 gas will gather at the bottom of the space after leakage, which will cause the SF6 gas to leak. Due to the high density of SF6 gas, SF6 gas will gather at the bottom of the space after leakage, resulting in the appearance of equipment. In the early stage of detection, SF6 drops to the detection point, and as time goes by, SF6 continues to drop and gathers below the detection point. As the concentration increases, the detection point cannot accurately capture it, resulting in inaccurate detection. In addition, during the detection process, since it is relatively close to the ground, it will cause the adsorption of debris on the ground during the leakage detection process, which will affect the accuracy of SF6 gas detection. Therefore, the device is provided with an absorption warning mechanism 5 for quickly sucking and detecting the concentration of SF6 gas. When the preset concentration threshold is reached, the signal is transmitted to the staff, and the staff will handle it in time.

[0039] It should be noted that the transmission antenna structure 3 and the identification structure 4 are antennas used for signal transmission in existing mature smart cars and environment identification devices that can judge the surrounding environment during the movement of the vehicle.

[0040] Example 2

[0041] During the process of the device detecting the SF6 gas concentration in the venue, the lower space or the middle space is continuously detected. Such detection is one-sided. Since the density of SF6 gas is relatively large, the SF6 gas will dynamically settle over time during the detection process. This makes the detection data of the device inaccurate. Therefore, the device is provided with a circulating lifting structure that continuously performs dynamic lifting during the detection process to ensure that the device detects a larger space range during the detection process, thereby better detecting the SF6 gas concentration.

[0042] like Figure 3 and Figure 4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the circulating lifting structure also includes a plurality of connecting columns 15 equidistantly fixedly installed on the inner top of the vehicle body 2, the bottom ends of the plurality of connecting columns 15 are respectively fixedly connected to the upper surfaces of a plurality of mounting plates 16, a connecting pipe 17 is provided under the mounting plate 16, connecting ear plates 18 are symmetrically fixedly installed on both sides of the connecting pipe 17, the bottom ends of the plurality of connecting columns 15 pass through the mounting plate 16 and the connecting ear plates 18 and are slidably connected to each other, the bottom ends of the plurality of connecting columns 15 are sleeved with auxiliary springs 19, and the auxiliary springs 19 are arranged between the mounting plate 16 and the connecting ear plates 18, and cams 14 are fixedly installed at both ends of the plurality of cross bars 8, and the cams 14 are squeezed and fitted with the connecting pipes 17.

[0043] In this embodiment, when the device is moving, the driving motor 13 drives the synchronous belt structure 11 to rotate synchronously, thereby driving the first bevel gear 9 and the second bevel gear 12 to rotate. As the two rotate, the cross bar 8 can be driven to drive the cam 14 to perform a cyclic circular motion. As the cam 14 moves periodically, the cam 14 will squeeze the connecting tube 17. As the cam 14 squeezes the connecting tube 17, the connecting tube 17 will periodically move upward. As the connecting tube 17 moves, the connecting tube 17 will drive the gas absorption detection structures distributed at both ends to rise and fall periodically, thereby increasing the detection space of the gas absorption detection structure. Further, in conjunction with the physical properties of SF6 gas, the gas in a larger space can be detected quickly and evenly, thereby avoiding the problem of insufficient detection accuracy due to the dynamic sedimentation of SF6 gas and the single space detection of the device.

[0044] It should also be noted that: as the cam 14 squeezes the connecting tube 17, the connecting tube 17 will move upward, and in order to increase the fit between the connecting tube 17 and the cam 14, auxiliary springs 19 are provided on both sides of the connecting tube 17, which can make the connecting tube 17 and the cam 14 in a tight fit, thereby increasing the stability of the device during operation and further improving the continuity of the device's operation.

[0045] like Figure 3 and Figure 4 As shown, preferably, the two synchronous belt structures 11 are diagonally arranged, the two synchronous belt structures 11 are linearly arranged, and the head and tail are coaxially connected.

[0046] In this embodiment, the synchronous belt structure 11 connected coaxially at the head and tail can quickly drive the second bevel gear 12 to rotate, and the diagonally arranged synchronous belt structure 11 can further improve the installation fit between the two synchronous belt structures 11, improve the installation fit of the mechanical structure, thereby improving the smoothness of the device during operation, thereby better detecting the concentration of SF6 gas.

[0047] like Figure 3 and Figure 4 As shown, preferably, the connecting pipe 17 is symmetrically provided with a matching collar which is pressed and matched with the cam 14 .

[0048] In this embodiment, the matching rings at both ends of the connecting tube 17 can improve the wear resistance of the connecting tube 17, avoid the long-term extrusion and friction of the cam 14 causing wear on the outer wall of the connecting tube 17, thereby reducing the transmission coordination and accuracy between the device components. The matching rings can improve the smoothness of the device during operation and reduce the failure rate of the equipment.

[0049] Example 3

[0050] like Figure 5-Figure 8As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the gas absorption detection structure includes a plurality of vertical pipes 20 respectively fixedly installed at both ends of the connecting pipe 17, a connecting seat 21 is fixedly installed at the bottom end of the vertical pipe 20, a guide pipe 22 is fixedly installed equidistantly inside the connecting seat 21, a guide seat 23 is fixedly installed at one end of the guide pipe 22 away from the connecting seat 21, a shielding net 24 is fixedly installed on one side of the guide seat 23, the middle parts of the plurality of connecting pipes 17 are fixedly connected by a conveying hose 25, the bottom end of the conveying hose 25 is fixedly connected to the input end of the gas filtering structure 26, and the gas filtering structure 26 is fixedly installed at the bottom end of the vehicle body 2, the output end of the gas filtering structure 26 is fixedly connected to the input end of the air pump 28 through the conveying pipe 27, the output end of the air pump 28 is fixedly connected to the input end of the SF6 gas detection device 29, the output end of the SF6 gas detection device 29 is fixedly installed with an outlet pipe 30, and the end of the outlet pipe 30 away from the SF6 gas detection device 29 is fixedly connected to the side wall of the vehicle body 2.

[0051] In this embodiment, during the movement of the device, the connecting pipe 17 is driven by the cam 14 to perform periodic reciprocating motion. As the connecting pipe 17 rises and falls, the vertical pipe 20 and the connecting seat 21 cooperate to rise and fall with it. A plurality of guide pipes 22 for extracting air are circumferentially installed on the connecting seat 21. In order to prevent debris on the ground from entering the interior of the device during the process of extracting air and affecting the detection accuracy of the device, a guide seat 23 and a shielding net 24 are provided at the end of the guide pipe 22, which can further increase the contact area with the air during the extraction, and can also isolate the debris on the ground to prevent the debris from entering. As the guide tube 22 draws the external air into the interior of the device, the delivery hose 25 delivers the air to the gas filter structure 26, and the air is further filtered by the gas filter structure 26 to filter out fine matter such as dust in the air. After that, the air enters the SF6 gas detection device 29 for concentration detection. In this process, in order to increase the intensity of the gas during the extraction process, an air pump 28 is provided on the gas absorption detection structure, which can continuously provide a certain intensity of suction force to better extract the air, so that the air pump 28 can detect the concentration.

[0052] It should be noted that the SF6 gas detection device 29 is an existing mature SF6 gas concentration detection device.

[0053] like Figure 5-Figure 8 As shown, preferably, a detachable filter mesh structure 31 is installed inside the gas filter structure 26 .

[0054] In this embodiment, the detachable filter mesh structure 31 can further improve the operability of the device, so that the gas filtering structure 26 can maintain a high filtering efficiency for a long time, thereby keeping the air entering the air pump 28 at a high level of cleanliness, avoiding long-term operation that causes dust accumulation, reduces the detection sensitivity of the air pump 28, and makes detection inconvenient.

[0055] like Figure 5-Figure 8 As shown, preferably, the side wall of the vehicle body 2 is equidistantly provided with matching grooves for slidingly matching with the connecting pipe 17 to limit the lifting and lowering of the connecting pipe 17 .

[0056] In this embodiment, the matching grooves on both sides of the vehicle body 2 can limit the running trajectory of the connecting pipe 17, further improve the accuracy of the connecting pipe 17 during the lifting process, increase the matching accuracy between components, and thus improve the operating stability of the device.

[0057] The working principle of the mobile SF6 gas leakage self-priming detection and early warning device is described in detail below.

[0058] like Figure 1-Figure 8As shown, during the operation of the driving device, the mobile platform 1 can cooperate with the transmission antenna structure 3 and the identification structure 4 to further improve the stability of the device during operation. When the device is moving, the driving motor 13 drives the synchronous belt structure 11 to rotate synchronously, thereby driving the first bevel gear 9 and the second bevel gear 12 to rotate. As the two rotate, the cross bar 8 can be driven to drive the cam 14 to perform a cyclic circular motion. As the cam 14 moves periodically, the cam 14 will squeeze the connecting tube 17. As the cam 14 squeezes the connecting tube 17, the connecting tube 17 will periodically move upward. As the connecting tube 17 moves, the connecting tube 17 will drive the gas absorption detection structures distributed at both ends to perform periodic lifting and lowering. At this time, the connecting tube 17 is driven by the cam 14 to perform periodic reciprocating motion. As the connecting tube 17 rises and falls, the vertical tube 20 and the connecting seat 21 cooperate to perform follow-up lifting and lowering, and the connecting seat 21 is circumferentially installed. There are several guide pipes 22 for extracting air. In order to prevent debris on the ground from entering the interior of the device during the air extraction process and affecting the detection accuracy of the device, a guide seat 23 and a shielding net 24 are provided at the end of the guide pipe 22, which can further increase the contact area with the air during air extraction, and can also isolate the debris on the ground to prevent the debris from entering the interior of the device. After the guide pipe 22 draws the external air into the interior of the device, the delivery hose 25 delivers the air to the gas filter structure 26, and the air is further filtered by the gas filter structure 26 to filter out fine substances such as dust in the air. After that, the air enters the SF6 gas detection device 29 for concentration detection. In this process, in order to increase the intensity of the gas during the extraction process, an air pump 28 is provided on the gas absorption detection structure, which can continuously provide a certain intensity of suction force to better extract the air, so that the air pump 28 can detect the concentration.

[0059] 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 depart from the spirit of the present invention are within the scope of protection of the present invention.
