Description

Technical Field

[0001] The invention relates to the technical field of power distribution station monitoring, and in particular to an all-round intelligent monitoring structure for indoor use in a power distribution station. Background Art

[0002] As we all know, with the development of the power industry, the distribution station, as an important part of the power system, its operation safety and stability are of vital importance. At present, the distribution station is usually equipped with a full range of intelligent monitoring structures to monitor the equipment operation status, environmental parameters and other information in real time.

[0003] SF6 gas has good insulation and arc extinguishing properties and is widely used in distribution stations. However, the density of SF6 gas is greater than that of air. Once a leak occurs, it will accumulate near the ground and is not easy to spread. Long-term exposure to a high-concentration SF6 gas environment can cause serious harm to human health, such as difficulty breathing, dizziness, nausea and other symptoms, and may even be life-threatening. At the same time, SF6 gas is a greenhouse gas with a high greenhouse effect potential. Large-scale leakage will have an adverse impact on the environment.

[0004] The existing monitoring structure mainly focuses on data collection and analysis. There is a lack of effective emergency response measures for sudden SF6 gas leakage incidents, and effective measures cannot be taken in time to reduce gas concentration and prevent its spread, resulting in the continued expansion of hazards. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides an all-round intelligent monitoring structure for use in a distribution station room, which has the advantages of being able to realize all-round intelligent monitoring of the distribution station room, and being able to quickly initiate effective treatment measures when SF6 gas leakage is detected, thereby reducing the SF6 gas concentration, preventing its diffusion, and ensuring personnel safety and environmental safety.

[0007] (II) Technical solution

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: an all-round intelligent monitoring structure for indoor use in a power distribution station, comprising a suspension track, a multi-stage telescopic arm is arranged at the bottom of the suspension track, a controller is bolted to the bottom of the multi-stage telescopic arm, and a pan-tilt is bolted to the bottom of the controller, image collectors are arranged on both sides of the pan-tilt, and a processing structure is arranged at the bottom of the pan-tilt, an SF6 gas concentration detector and an SF6 gas leakage detector are bolted to the front and left sides of the controller respectively, a compressed gas tank is arranged on the top of the surface of the multi-stage telescopic arm, and the compressed gas tank is connected to the processing structure through a pipeline;

[0009] The processing structure includes a fixed cylinder, which is arranged at the bottom of the pan-tilt head. A nitrogen injection pipe is arranged inside the fixed cylinder, and an anti-diffusion component is arranged on the surface of the fixed cylinder. The anti-diffusion component is used in conjunction with the nitrogen injection pipe. A push ring is slidingly arranged on the right side inside the fixed cylinder, and a push rod is bolted to the left side of the push ring. The push rod is used in conjunction with the anti-diffusion component.

[0010] By adopting the above technical solution and setting up a processing structure, it is possible to respond to SF6 gas leakage in the first time while comprehensively monitoring various parameters in the distribution station room and take effective treatment measures. By using the nitrogen injection pipe, compressed gas tank and anti-diffusion component in coordination, through precise airflow guidance and dynamic barrier adjustment, SF6 gas can be efficiently diluted and its diffusion can be effectively prevented, thereby reducing the harm of SF6 gas to personnel and equipment and improving the safety and reliability of the distribution station.

[0011] Efficient gas dilution and diffusion prevention: The innovative design of the nitrogen dilution device and the airflow barrier device can quickly and effectively reduce the SF6 gas concentration and prevent its diffusion. The rotatable nitrogen nozzle and adjustable airflow generator make the treatment measures more flexible and accurate, and improve the treatment efficiency.

[0012] The present invention is further configured as follows: a variable speed fan structure is arranged at the rear side of the interior of the fixed cylinder, and a flow hole used in conjunction with the variable speed fan structure is opened inside the push ring.

[0013] By adopting the above technical solution, by setting a variable speed fan structure in cooperation with the flow holes on the push ring, the airflow in the fixed cylinder can be controlled to enhance the nitrogen injection effect, and the push ring and the push rod can be moved, thereby adjusting the range of the airflow barrier formed by the anti-diffusion component, thereby improving the flexibility of use.

[0014] The present invention is further configured as follows: the anti-diffusion component includes a moving ring, the moving ring is sleeved on the surface of the nitrogen injection pipe, and the moving ring is slidably arranged inside the fixed cylinder, the surface of the fixed cylinder is provided with a plurality of guide plates that rotate in a ring shape, a guide ring is sleeved on the right side of the surface of the fixed cylinder, and the guide ring is used in conjunction with the guide plate, the surface of the moving ring and the inner wall of the guide plate are both provided with connecting brackets, and a connecting rod is rotatably connected between two adjacent connecting brackets.

[0015] By adopting the above technical solution and setting an anti-diffusion component, the airflow generated by the variable speed fan structure can move the push ring and the push rod, thereby pushing the moving ring to slide in the fixed cylinder. The moving ring drives the guide plate to rotate through the connecting bracket and the connecting rod. The angle of the guide plate changes, thereby changing the flow direction of the gas, forming a barrier to block the diffusion of SF6 gas, and the guide ring guides the gas generated by the variable speed fan structure, so that part of the fresh air and part of the nitrogen are mixed in the guide ring and flow along the specific path of the guide plate, further enhancing the anti-diffusion effect.

[0016] The present invention is further configured as follows: an end cover is bolted to the front side of the fixed cylinder, and the left side of the nitrogen injection pipe extends to the outside of the end cover, two return springs are arranged on the left side of the movable ring, and the other side of the return spring is connected to the end cover.

[0017] By adopting the above technical solution, the end cover is arranged and fixed on the front side of the fixed cylinder to support and position the nitrogen injection pipe, thereby ensuring the stability of the nitrogen injection pipe. When the push rod pushes the moving ring, the moving ring moves to the left under the pressure and compresses the reset spring. When the variable speed fan structure is not working, the elastic force of the reset spring causes the moving ring to move to the right and return to its initial position, driving the guide plate to return to its initial state, thereby preparing for the next non-diffusion operation.

[0018] The present invention is further configured as follows: the guide ring includes a ring body, the ring body is sleeved on the right side of the surface of the fixed cylinder, and the interior of the ring body is provided with a plurality of guide holes in a ring shape, an upper support plate and a lower support plate are respectively provided inside the guide holes, and a spiral guide plate is provided between the opposite sides of the upper support plate and the lower support plate.

[0019] By adopting the above technical solution, by setting a guide ring, part of the nitrogen passes through the nitrogen injection pipe and part of the fresh air into the guide hole, and part of the nitrogen and fresh air are mixed through the spiral guide plate, and then flow along the flow path of the guide plate, thereby more effectively diluting the SF6 gas and further enhancing the anti-diffusion effect.

[0020] The present invention is further configured as follows: a plurality of injection holes are provided in a ring shape on the right side inside the nitrogen injection pipe, and the injection holes are used in conjunction with the guide holes, and the positions of the injection holes correspond one to one with the guide holes.

[0021] By adopting the above technical solution, by setting the injection hole, the effect of cooperating with the guide hole can be achieved, ensuring that the nitrogen can accurately enter the guide hole, realizing precise guidance and mixing of the gas, improving the stability and reliability of the treatment effect, and ensuring that the SF6 gas can be effectively diluted in different positions and situations.

[0022] The present invention is further configured as follows: a flexible connecting sheet is provided between two adjacent guide plates, and the flexible connecting sheet is provided in a corrugated shape.

[0023] By adopting the above technical solution, by setting a flexible connecting piece, the connection flexibility between adjacent guide plates can be ensured, so that the guide plates can rotate freely according to the gas flow conditions, and a closed state can be formed between adjacent guide plates, which can block the leakage of gas between two adjacent guide plates to a certain extent and enhance the anti-diffusion effect.

[0024] The present invention is further configured as follows: an elastic connecting ring is welded on the left side of the nitrogen injection pipe, and a plurality of adjusting plates are welded in a ring shape on the left side of the elastic connecting ring, and the surfaces of the adjusting plate and the nitrogen injection pipe are both provided with fixing frames, and an electric cylinder is rotatably connected between the two fixing frames on both sides.

[0025] By adopting the above technical solution, the flexibility of the nitrogen injection pipe is increased by arranging the elastic connecting ring and the adjusting plate, and the injection direction and angle of the nitrogen can be adjusted according to actual needs, thereby improving the coverage and dilution effect of the nitrogen. After being started by the electric cylinder, the adjusting plate is driven to rotate around the elastic connecting ring, so that the adjusting plates can expand or contract, thereby adjusting the injection range of the nitrogen and improving the dilution effect on the SF6 gas.

[0026] The present invention is further configured as follows: the surface of the multi-stage telescopic arm is rotatably connected to two support rings through bearings, and the surface of the support ring is welded with a fixing ring in an annular shape, the compressed gas tank includes a main nitrogen bottle and a plurality of auxiliary nitrogen bottles, and the main nitrogen bottle is located between two adjacent fixing rings on the front side, a plurality of connecting pipes are arranged between the auxiliary nitrogen bottles and the main nitrogen bottle, and the main nitrogen bottle is connected to the nitrogen injection pipe through a flexible and retractable pipeline.

[0027] By adopting the above technical solution, a support ring and a fixed ring are set to provide stable support for the compressed gas tank to ensure that the gas tank will not shake or fall during the movement of the monitoring structure. The combined design of the main nitrogen cylinder and the auxiliary nitrogen cylinder increases the storage capacity of nitrogen, ensuring that nitrogen can be continuously provided for a long time to dilute the SF6 gas. The flexible retractable pipeline ensures that the nitrogen can be smoothly transported to the nitrogen injection pipe during the extension and retraction of the multi-stage telescopic arm.

[0028] The present invention is further configured as follows: two sealing plates are arranged inside the connecting tube, and the two sealing plates are symmetrically arranged inside the connecting tube, moving rods are welded on the opposite sides of the two sealing plates, and a pressure spring is sleeved on the surface of the moving rod, and the pressure spring is connected to the sealing plate and the inner wall of the connecting tube respectively on one side thereof.

[0029] By adopting the above technical solution, a sealing plate is provided. When the nitrogen in the main nitrogen cylinder is used up, the pressure in the main nitrogen cylinder decreases. At this time, the elastic force of the pressure spring can release the sealing plate from blocking the connecting pipe, thereby opening the channel in the connecting pipe. Therefore, nitrogen flows from the auxiliary nitrogen cylinder to the main nitrogen cylinder, ensuring a sufficient supply of nitrogen, thereby replenishing the nitrogen in the main nitrogen cylinder.

[0030] (III) Beneficial effects

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1

[0043] See also Figure 1-7 , an all-round intelligent monitoring structure for indoor use in a power distribution station, comprising a suspension track 1, a multi-stage telescopic arm 2 is arranged at the bottom of the suspension track 1, a controller 3 is bolted to the bottom of the multi-stage telescopic arm 2, and a pan / tilt 4 is bolted to the bottom of the controller 3, image collectors 5 are arranged on both sides of the pan / tilt 4, and a processing structure 6 is arranged at the bottom of the pan / tilt 4, an SF6 gas concentration detector 7 and an SF6 gas leakage detector 8 are bolted to the front and left sides of the controller 3, respectively, a compressed gas tank 9 is arranged on the top of the surface of the multi-stage telescopic arm 2, and the compressed gas tank 9 is connected to the processing structure 6 through a pipeline;

[0044] The processing structure 6 includes a fixed cylinder 61, which is arranged at the bottom of the pan / tilt head 4. A nitrogen injection pipe 62 is arranged inside the fixed cylinder 61, and an anti-diffusion component 63 is arranged on the surface of the fixed cylinder 61. The anti-diffusion component 63 is used in conjunction with the nitrogen injection pipe 62. A push ring 64 is slidingly arranged on the right side inside the fixed cylinder 61, and a push rod 65 is bolted to the left side of the push ring 64. The push rod 65 is used in conjunction with the anti-diffusion component 63. Through the processing structure 6, when comprehensively monitoring various parameters in the distribution station room, it is also possible to respond to SF6 gas leakage in the first time and take effective processing measures. Through the coordinated use of the nitrogen injection pipe 62, the compressed gas tank 9 and the anti-diffusion component 63, through precise airflow guidance and dynamic barrier adjustment, the SF6 gas can be efficiently diluted and its diffusion can be effectively prevented, reducing the harm of SF6 gas to personnel and equipment, and improving the safety and reliability of the distribution station.

[0045] Among them, a variable-speed fan structure is arranged on the rear side of the fixed cylinder 61, and a flow hole 10 used in conjunction with the variable-speed fan structure is opened inside the push ring 64. By setting the variable-speed fan structure in conjunction with the flow hole 10 on the push ring 64, the airflow in the fixed cylinder 61 can be controlled to enhance the nitrogen injection effect, and the push ring 64 and the push rod 65 can be moved, thereby adjusting the range of the airflow barrier formed by the anti-diffusion component 63, thereby improving the flexibility of use.

[0046] Among them, an elastic connecting ring 15 is welded on the left side of the nitrogen injection pipe 62, and a plurality of adjusting plates 16 are welded in a ring shape on the left side of the elastic connecting ring 15. The surfaces of the adjusting plates 16 and the nitrogen injection pipe 62 are provided with fixing frames 17, and an electric cylinder 18 is rotatably connected between the two fixing frames 17 on both sides. The flexibility of the nitrogen injection pipe 62 is increased by setting the elastic connecting ring 15 and the adjusting plates 16, and the injection direction and angle of nitrogen can be adjusted according to actual needs, thereby improving the coverage range and dilution effect of nitrogen. After the electric cylinder 18 is started, the adjusting plates 16 are driven to deform around the elastic connecting ring 15, so that the adjusting plates 16 can expand or contract, thereby adjusting the injection range of nitrogen and improving the dilution effect of SF6 gas.

[0047] Among them, the surface of the multi-stage telescopic arm 2 is rotatably connected to two support rings 19 through bearings, and the surface of the support ring 19 is welded with a fixing ring 20 in a ring shape. The compressed gas tank 9 includes a main nitrogen cylinder 21 and a plurality of auxiliary nitrogen cylinders 22, and the main nitrogen cylinder 21 is located between two adjacent fixing rings 20 on the front side. A plurality of connecting pipes 23 are arranged between the auxiliary nitrogen cylinder 22 and the main nitrogen cylinder 21. The main nitrogen cylinder 21 is connected to the nitrogen injection pipe 62 through a flexible and retractable pipeline. The support ring 19 and the fixing ring 20 are arranged to provide stable support for the compressed gas tank 9, ensuring that the gas tank will not shake or fall during the movement of the monitoring structure. The combined design of the main nitrogen cylinder 21 and the auxiliary nitrogen cylinder 22 increases the storage capacity of nitrogen, ensuring that nitrogen can be continuously provided for a long time for dilution treatment of SF6 gas, and the flexible and retractable pipeline ensures that the nitrogen can be smoothly transported to the nitrogen injection pipe 62 during the extension and retraction of the multi-stage telescopic arm 2.

[0048] Among them, two sealing plates 24 are arranged inside the connecting pipe 23, and the two sealing plates 24 are symmetrically arranged in the connecting pipe 23. Moving rods 25 are welded on the opposite sides of the two sealing plates 24, and the surface of the moving rods 25 is sleeved with a pressure spring 26. The pressure spring 26 is connected to the sealing plate 24 and the inner wall of the connecting pipe 23 on one side close to the sealing plate 24 and the inner wall of the connecting pipe 23 respectively. By setting the sealing plates 24, when the nitrogen in the main nitrogen cylinder 21 is used up, due to the reduction of the pressure in the main nitrogen cylinder 21, the elastic force of the pressure spring 26 can release the sealing plate 24 from blocking the connecting pipe 23, so that the channel in the connecting pipe 23 is opened, so that nitrogen flows from the auxiliary nitrogen cylinder 22 to the main nitrogen cylinder 21, ensuring sufficient supply of nitrogen and playing the effect of replenishing the nitrogen in the main nitrogen cylinder 21.

[0049] Working principle of this embodiment: when the SF6 gas concentration detector 7 and the SF6 gas leakage detector 8 detect SF6 gas leakage and concentration, the nitrogen injection pipe 62 is moved to the leakage position through the coordinated use of the multi-stage telescopic arm 2 and the pan / tilt head 4, and at the same time, the nitrogen in the main nitrogen cylinder 21 enters the nitrogen injection pipe 62 through the pipeline and is ejected, and according to the leakage range, the electric cylinder 18 is started to drive the adjustment piece 16 to deform around the elastic connecting ring 15, so that the adjustment pieces 16 can expand or contract, thereby adjusting the injection range of the nitrogen and realizing the dilution treatment of the SF6 gas. When the nitrogen in the main nitrogen cylinder 21 is used up, due to the reduction of the pressure in the main nitrogen cylinder 21, the elastic force of the pressure spring 26 can be used to release the sealing plate 24 from the connecting pipe 23, so that the channel in the connecting pipe 23 is opened, so that the nitrogen flows from the auxiliary nitrogen cylinder 22 to the main nitrogen cylinder 21, ensuring sufficient supply of nitrogen.

[0050] Example 2

[0051] refer to Figure 5A omnidirectional intelligent monitoring structure for indoor use in a power distribution station also includes an anti-diffusion component 63, wherein the anti-diffusion component 63 includes a moving ring 631, the moving ring 631 is sleeved on the surface of the nitrogen injection pipe 62, and the moving ring 631 is slidably arranged inside the fixed cylinder 61, and the surface of the fixed cylinder 61 is provided with a plurality of guide plates 632 in a circular rotation, and a guide ring 633 is sleeved on the right side of the surface of the fixed cylinder 61, and the guide ring 633 is used in conjunction with the guide plate 632, and the surface of the moving ring 631 and the inner wall of the guide plate 632 are both provided with a connecting bracket 634, and a connecting rod 635 is rotatably connected between two adjacent connecting brackets 634, through By setting up the anti-diffusion component 63, the airflow generated by the variable speed fan structure can move the push ring 64 and the push rod 65, thereby pushing the movable ring 631 to slide in the fixed tube 61. The movable ring 631 drives the guide plate 632 to rotate through the connecting bracket 634 and the connecting rod 635. The angle of the guide plate 632 changes, thereby changing the flow direction of the gas, forming a barrier to block the diffusion of SF6 gas, and the guide ring 633 guides the gas generated by the variable speed fan structure, so that part of the fresh air and part of the nitrogen are mixed in the guide ring 633 and flow along the specific path of the guide plate 632, further enhancing the anti-diffusion effect.

[0052] Among them, the end cover 11 is bolted to the front side of the interior of the fixed cylinder 61, and the left side of the nitrogen injection pipe 62 extends to the outside of the end cover 11. Two return springs 12 are arranged on the left side of the movable ring 631, and the other side of the return spring 12 is connected to the end cover 11. By setting the end cover 11 to be fixed to the front side of the interior of the fixed cylinder 61, the nitrogen injection pipe 62 is supported and positioned to ensure the stability of the nitrogen injection pipe 62. When the push rod 65 pushes the movable ring 631, the movable ring 631 moves to the left due to the pressure and compresses the return spring 12. When the variable speed fan structure is not working, the elastic force of the return spring 12 causes the movable ring 631 to move to the right and return to the initial position, driving the guide plate 632 to return to the initial state, and preparing for the next non-diffusion operation.

[0053] Among them, the guide ring 633 includes a ring body 633a, which is sleeved on the right side of the surface of the fixed cylinder 61, and the interior of the ring body 633a is provided with a plurality of guide holes 633b in a ring shape, and the interior of the guide hole 633b is respectively provided with an upper support plate 633c and a lower support plate 633d, and a spiral guide plate 633e is provided between the opposite sides of the upper support plate 633c and the lower support plate 633d. By setting the guide ring 633, part of the nitrogen passes through the nitrogen injection pipe 62 and part of the fresh air into the guide hole 633b, and part of the nitrogen and the fresh air are mixed through the spiral guide plate 633e, and then flow according to the flow path of the guide plate 632, so as to more effectively dilute the SF6 gas and further enhance the anti-diffusion effect.

[0054] Among them, a plurality of injection holes 13 are provided in a ring shape on the right side inside the nitrogen injection pipe 62, and the injection holes 13 are used in conjunction with the guide holes 633b. The positions of the injection holes 13 correspond one to one with the guide holes 633b. By setting the injection holes 13, the guide holes 633b can be used in conjunction with the guide holes 633b, ensuring that the nitrogen can accurately enter the guide holes 633b, achieving precise guidance and mixing of the gas, improving the stability and reliability of the treatment effect, and ensuring that the SF6 gas can be effectively diluted in different positions and conditions.

[0055] Among them, a flexible connecting piece 14 is arranged between two adjacent guide plates 632, and the flexible connecting piece 14 is arranged in a corrugated shape. By setting the flexible connecting piece 14, it can not only ensure the connection flexibility between the adjacent guide plates 632, so that the guide plates 632 can rotate freely according to the gas flow conditions, but also form a closed state between the adjacent guide plates 632, which can block the leakage of gas between the two adjacent guide plates 632 to a certain extent and enhance the anti-diffusion effect.

[0056] The working principle of this embodiment is as follows: while diluting the SF6 gas, an air flow is generated through the variable speed fan structure, so that the push ring 64 and the push rod 65 can move in the fixed tube 61, and push the moving ring 631 to move. The moving ring 631 drives the guide plate 632 to rotate through the connecting bracket 634 and the connecting rod 635, and the angle of the guide plate 632 changes, thereby changing the flow direction of the gas, forming a barrier to block the diffusion of SF6 gas, and the fresh air generated by the variable speed fan structure enters the guide hole 633b through the circulation hole 10 and part of the nitrogen enters the guide hole 633b through the injection hole 13. And part of the nitrogen and fresh air are mixed through the spiral guide plate 633e, and then flow along the flow path of the guide plate 632, so as to dilute the SF6 gas more effectively and further enhance the anti-diffusion effect. When the push rod 65 pushes the moving ring 631, the moving ring 631 moves to the left due to the pressure and compresses the reset spring 12. When the SF6 gas processing work is completed, the variable speed fan structure is no longer working. At this time, the elastic force of the reset spring 12 causes the moving ring 631 to move to the right and return to its initial position, driving the guide plate 632 to return to its initial state, preparing for the next anti-diffusion operation.
