Description

Technical Field

[0001] The present invention relates to the technical field of disconnect switches, in particular to an installation and protection mechanism for a fully enclosed high-voltage disconnect switch. Background Art

[0002] A disconnect switch is a switch device mainly used for "isolating power sources, performing switching operations, and connecting and disconnecting small-current circuits", and is widely used in power systems. When the disconnect switch is used outdoors, in order to prevent it from being affected by rain or other sundries, the disconnect switch needs to be installed inside a box with a protective function. In order to allow the inside of the box to breathe and dissipate heat, the box is provided with ventilation mesh holes. Due to the existence of the ventilation mesh holes, the box cannot be tightly sealed. When there is heavy rain or strong wind, rain or sand and gravel will enter the inside of the box. After the rain enters the box, it may adhere to the surface of the insulating components of the disconnect switch, resulting in a decrease in insulation resistance, and it is easy to cause surface discharge under high-voltage environments, and even cause phase-to-phase short circuit or ground short circuit faults. After sand and gravel and other sundries enter the box, they may accumulate in mechanical moving parts such as transmission gears and connecting rods, hindering the normal operation of the components, increasing mechanical wear, reducing transmission efficiency, and may cause damage to the mechanism in the long term, affecting the normal operation of the disconnect switch.

Specific embodiments

[0027] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. Embodiment 1

[0030] Refer to Figures 1 - 3 and Figure 10, which is the first embodiment of the present invention. This embodiment provides an installation protection mechanism for a fully enclosed high-voltage disconnector. The installation protection mechanism of the fully enclosed high-voltage disconnector includes a main body assembly 100, which includes a protection box body 101. A protection door 102 is provided on one side of the protection box body 101. Inside the protection box body 101, there is a disconnector 103, which is used to isolate the power supply, perform switching operations, and connect and disconnect small current circuits. The protection box body 101 is used to install the disconnector 103 and protect the disconnector 103, and the protection door 102 is used to close the protection box body 101. After the protection door 102 is closed, it can effectively protect the disconnector 103.

[0031] A ventilation net 104 is provided on one side of the protection box body 101. The ventilation net 104 can enable the heat inside the protection box body 101 to circulate and be discharged outward, avoiding the situation of excessive temperature inside the protection box body 101. The mesh diameter of the ventilation net 104 is ≤0.3 mm, and the mesh surface is treated with a hydrophobic coating. Small raindrops form bead-like rolling on the surface and cannot penetrate into the protection box body 101. The ventilation net 104 is a double-layer net structure and forms a dust-proof filter layer. When the wind speed is ≤6 levels, dust particles cannot penetrate the mesh holes, ensuring that the mechanical components inside the protection box body 101 are not affected by sundries. The porosity design of the ventilation net 104 takes into account the dust-proof and heat dissipation requirements. Under normal weather conditions, the air circulation rate inside and outside the box body is ≥0.5 m / s, ensuring that the operating temperature of the disconnector 103 does not exceed the rated value.

[0032] Under the weather conditions of rainfall ≤50 mm / h and wind speed ≤6 levels, the ventilation net 104 can independently block the intrusion of rain and sand, and at the same time ensure that the heat dissipation efficiency of the box body is ≥90%. And a water guide groove (not shown in the figure) is provided at the bottom of the protection box body 101, and a small amount of rainwater inside the protection box body 101 can be discharged through the water guide groove.

[0033] This is the prior art, and this solution will not be elaborated much, and those skilled in the art can clearly understand the working principle.

[0034] An auxiliary assembly 200 is provided on the protection box body 101, which includes a seal 201. The seal 201 includes a seal frame 2011 fixed to one side of the protection box body 101. The seal frame 2011 is rectangular and is located around the ventilation net 104. The seal frame 2011 has elasticity. Two stabilizing blocks 2012 are fixed to one side of the protection box body 101. The number of stabilizing blocks 2012 is two, which are respectively located at both ends of the rotating column 2013. A rotating column 2013 is rotatably connected inside the stabilizing block 2012, and a baffle 2014 is provided on the outside of the rotating column 2013, and the baffle 2014 is in a horizontal state.

[0035] There is an activity slot 2014-1 opened inside the baffle 2014. On one side of the rotating column 2013, a push block 2016 is fixed. On one side of the push block 2016, a first spring 2017 is fixed. The push block 2016 is movably connected inside the activity slot 2014-1 and is in contact with the inner wall of the activity slot 2014-1 on one side. The other end of the first spring 2017 is fixed to the inner wall of the activity slot 2014-1. When the rotating column 2013 rotates, it will squeeze the inner wall of the activity slot 2014-1 through the push block 2016, thereby driving the baffle 2014 to rotate downward. When the rotating column 2013 rotates in the reverse direction and the baffle 2014 is restricted from rotating, at this time, the push block 2016 will compress the first spring 2017. When the restriction on the baffle 2014 is released, the inner wall of the activity slot 2014-1 can be squeezed by the first spring 2017, thereby pushing the baffle 2014 to rotate upward to the horizontal state.

[0036] When there are strong winds or heavy rain, the rotating column 2013 will drive the baffle 2014 to rotate downward to the vertical state. At this time, the baffle 2014 will be in contact with one side of the sealing frame 2011 and squeeze the sealing frame 2011. In this way, the breathable net 104 can be blocked through the cooperation of the baffle 2014 and the sealing frame 2011, thereby avoiding the situation that rainwater or sand and stones enter the inside of the protective box body 101. Embodiment 2

[0037] Refer to Figures 3 - 9 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

[0038] Specifically, the auxiliary component 200 further includes a trigger member 202. The trigger member 202 includes a collection frame 2021 fixed to the top of the protective box body 101. A filter screen is fixed to the top of the collection frame 2021. The filter screen can prevent sundries from falling inside the collection frame 2021. The inner wall of the collection frame 2021 is inclined, and the side where the drain pipe 2022 is located is the lower part. A drain pipe 2022 is fixed below one side of the collection frame 2021. The upper end of the drain pipe 2022 has a large diameter and the lower end has a small diameter, so that the water flow discharged from the drain pipe 2022 has a certain pressure.

[0039] The bottom end of the drain pipe 2022 is fixed with a fixing sleeve 2023. The fixing sleeve 2023 is sleeved outside the rotating column 2013. Drainage holes are opened at the bottom of the fixing sleeve 2023. A force-bearing plate 20211 is fixed to the outside of the rotating column 2013. The number of the force-bearing plates 20211 is two, which are respectively fixed to the outside of the rotating column 2013 in an arc shape. Activity slots are opened at the centers of the two force-bearing plates 2021l.

[0040] When heavy rain occurs, the hydrophobic ability of the breathable net 104 reaches its limit during a rainstorm. At this time, the rainwater is collected by the collection frame 2021 to prevent the rainwater from directly hitting the protective box body 101, which may cause the protective box body 101 to rust. The collected rainwater will flow downward through the drain pipe 2022 and enter the fixed sleeve 2023. At this time, the water flow will exert pressure on the force-bearing plate 20211 and push the force-bearing plate 20211 to rotate, causing the force-bearing plate 20211 to drive the rotating column 2013 and the baffle 2014 to rotate. In this way, the baffle 2014 can be rotated to a vertical state to block the breathable net 104.

[0041] Specifically, a support sleeve 2024 is fixed to the top of the collection frame 2021. The top of the support sleeve 2024 is rotatably connected to a rotating sleeve 2025. The rotating sleeve 2025 is rotatably connected to the outside of the support sleeve 2024 through a bearing. A support column 2026 is fixed to the top of the rotating sleeve 2025. A wind vane 2027 is fixed to the top of the support column 2026. A fixed column 2028 is fixed to the outside of the support column 2026. An axial flow fan 2029 is rotatably connected to the outside of the fixed column 2028. The axial flow fan 2029 is composed of a sleeve and multiple blades. The sleeve is rotatably connected to the outside of the fixed column 2028 through a bearing. A protective sleeve is fixed to the outside of the support column 2026, and the protective sleeve wraps the axial flow fan 2029. A filter screen is fixed at the air inlet of the axial flow fan 2029 to filter impurities in the air.

[0042] A pull rope 20210 is fixed to the outside of the rotating column 2013. The other end of the pull rope 20210 extends from the inside of the drain pipe 2022 all the way into the support sleeve 2024 and the support column 2026 and is fixed to the sleeve of the axial flow fan 2029.

[0043] The wind vane 2027 can drive the support column 2026 to rotate with the wind direction, and drive the fixed column 2028 and the axial flow fan 2029 to rotate through the support column 2026, so that the air inlet of the axial flow fan 2029 rotates to the windward direction. The interception efficiency of the breathable net 104 for strong wind and sand decreases with the increase of wind speed. When the wind speed exceeds the threshold value, the wind force will drive the axial flow fan 2029 to rotate. When the axial flow fan 2029 rotates, it will wind up the pull rope 20210 and drive the rotating column 2013 to rotate through the pull rope 20210, and then drive the baffle 2014 to rotate downward through the rotating column 2013.

[0044] After the baffle 2014 rotates to the vertical state, the axial flow fan 2029 cannot continue to rotate, and the continuous wind force will keep the axial flow fan 2029 in the current state continuously.

[0045] The pull rope 20210 is located inside the movable groove at the center of the force-bearing plate 20211. A stopper is fixed on the outer side of the rotating column 2013 to isolate the pull rope 20210 from the force-bearing plate 20211, so that the pull rope 20210 will not be wound around the force-bearing plate 20211.

[0046] Specifically, a torsion spring 2015 is fixed on the outer side of the rotating column 2013, and the other end of the torsion spring 2015 is fixed to the stable block 2012.

[0047] When the rain or wind stops, a torsional force can be applied to the rotating column 2013 through the torsion spring 2015, so that the rotating column 2013 rotates in the reverse direction and can drive the baffle 2014 to rotate to the horizontal state.

[0048] The elastic force of the torsion spring 2015 is greater than the elastic force of the first spring 2017. In this way, when the baffle 2014 is restricted from rotating, the first spring 2017 can drive the rotating column 2013 to rotate and make the push block 2016 compress the first spring 2017.

[0049] Specifically, the auxiliary component 200 further includes two locking members 203, which are respectively located on both sides of the baffle 2014. The locking member 203 includes a support frame 2031 fixed to one side of the protective box body 101. An activity frame 2032 is movably connected inside the support frame 2031, and a clamping block 2033 is arranged inside the activity frame 2032. One side of the clamping block 2033 is inclined.

[0050] Specifically, a second spring 2034 is fixed to the inner wall of the activity frame 2032, the other end of the second spring 2034 is fixed to the clamping block 2033, and an extrusion block 2035 is fixed to one side of the clamping block 2033. One side of the extrusion block 2035 is inclined.

[0051] When the rotating column 2013 rotates, the activity frame 2032 will drive the clamping block 2033 to move. At this time, when the baffle 2014 rotates to the vertical position, it will contact the inclined surface of the clamping block 2033 and push the clamping block 2033 to move. At the same time, the clamping block 2033 will squeeze the second spring 2034. After the baffle 2014 is vertical, the second spring 2034 will push the clamping block 2033 to move, so that the straight side of the clamping block 2033 contacts the baffle 2014, thereby locking the baffle 2014 and preventing it from moving, and further avoiding the situation that the baffle 2014 is loosened under the influence of strong wind or rain, which may lead to a decrease in the sealing effect.

[0052] When the second spring 2034 pushes the clamping block 2033 to move, the inclined surface of the extrusion block 2035 will squeeze the baffle 2014 and make the baffle 2014 fit more tightly with the sealing frame 2011, thereby increasing the sealing performance between the two.

[0053] The elastic force of the first spring 2017 is greater than that of the second spring 2034. In this way, when the baffle 2014 presses against the inclined surface of the latch 2033, it can push the latch 2033 to move instead of the baffle 2014 rotating. Embodiment 3

[0054] Refer to Figures 1 - 10 , which is the third embodiment of the present invention. This embodiment is based on the first two embodiments.

[0055] Specifically, the auxiliary component 200 further includes a rotating member 204. The rotating member 204 includes a positioning column 2041 fixed to one side of the movable frame 2032. A rotating sleeve 2042 is rotatably connected to one side of the support frame 2031. A fixed shaft 2043 is fixed inside the rotating sleeve 2042. A spiral groove 2041-1 is formed on the positioning column 2041, and the fixed shaft 2043 slides inside the spiral groove 2041-1.

[0056] Specifically, the auxiliary component 200 further includes a transmission member 205. The transmission member 205 includes a rotating rod 2051 fixed to one side of the rotating sleeve 2042. A pressing rod 2052 is fixed to one side of the rotating column 2013. A connecting rod 2053 is arranged on one side of the rotating rod 2051. A stabilizing frame (not shown in the figure) is fixed to one side of the protective box body 101. The connecting rod 2053 is movably connected inside the stabilizing frame. Positioning shafts 2054 are fixed to both ends on one side of the connecting rod 2053. Slide grooves 205-1 are formed on the rotating rod 2051 and the pressing rod 2052, and the two positioning shafts 2054 are respectively slidably connected inside the two slide grooves 205-1.

[0057] When the rotating column 2013 rotates, it will drive the pressing rod 2052 to rotate downward. The pressing rod 2052 drives the connecting rod 2053 and the rotating rod 2051 to rotate downward, and the rotating rod 2051 drives the rotating sleeve 2042 to rotate. At this time, the fixed shaft 2043 will slide inside the spiral groove 2041-1. Through the cooperation of the two, the positioning column 2041 is driven to move, so that the positioning column 2041 drives the movable frame 2032 to move.

[0058] When in use, when heavy rain occurs, the rainwater is collected by the collection box 2021 to prevent the rainwater from directly hitting the protective box body 101, which may cause the protective box body 101 to rust. The collected rainwater will flow downward through the drain pipe 2022 and enter the fixed sleeve 2023. At this time, the water flow will apply pressure to the force-bearing plate 20211 and push the force-bearing plate 20211 to rotate, so that the force-bearing plate 20211 drives the rotating column 2013 and the baffle 2014 to rotate. In this way, the baffle 2014 can be rotated to a vertical state and block the ventilation net 104, thus preventing rainwater from entering the inside of the protective box body 101.

[0059] When the rotating column 2013 rotates, it will drive the pressing rod 2052 to rotate downward. By driving the pressing rod 2052, the connecting rod 2053 and the rotating rod 2051 are driven to rotate downward, and the rotating rod 2051 drives the rotating sleeve 2042 to rotate. At this time, the fixed shaft 2043 will slide in the spiral groove 2041-1, and the positioning column 2041 is driven to move through the cooperation of the two, so that the positioning column 2041 drives the movable frame 2032 to move.

[0060] The movable frame 2032 drives the block 2033 to move. At this time, when the baffle 2014 rotates to the vertical position, it will contact the inclined surface of the block 2033 and push the block 2033 to move. At the same time, the block 2033 will squeeze the second spring 2034. After the baffle 2014 is vertical, the second spring 2034 pushes the block 2033 to move, so that one side of the straight surface of the block 2033 contacts the baffle 2014, thereby locking the baffle 2014 and preventing it from moving, and further avoiding the situation that the baffle 2014 is loosened under the influence of strong wind or rain, resulting in a reduction in the sealing effect. When the second spring 2034 pushes the block 2033 to move, the inclined surface of the extrusion block 2035 squeezes the baffle 2014, and makes the baffle 2014 fit more tightly with the sealing frame 2011, thereby increasing the sealing performance between the two.

[0061] When there is a strong wind, the wind vane 2027 can drive the support column 2026 to rotate with the wind direction, and drive the fixed column 2028 and the axial flow fan 2029 to rotate through the support column 2026, so that the air inlet of the axial flow fan 2029 rotates to the windward direction. At this time, the wind force will drive the axial flow fan 2029 to rotate. When the axial flow fan 2029 rotates, it will wind up the pull rope 20210, and drive the rotating column 2013 to rotate through the pull rope 20210. Furthermore, the baffle 2014 can be driven to rotate downward by the rotating column 2013, so that the baffle 2014 can block the ventilation net 104 in strong wind weather, thus avoiding the situation that sand and gravel enter the interior of the protection box body 101. It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
