Description

Technical Field

[0001] The present invention relates to the technical field of lightning impulse simulation equipment, in particular to a movable lightning impulse simulation equipment. Background Art

[0002] The lightning impulse simulator is a test device designed specifically to simulate the natural lightning impulse effects. It generates high-voltage, short-pulse shock waves to simulate the direct or indirect impact of lightning on key systems such as power equipment, communication facilities, and aerospace vehicles, thereby evaluating the impact resistance of key systems such as power equipment, communication facilities, and aerospace vehicles. Due to its high-precision simulation capabilities, safety, and easy operation, it is often used in power system testing, scientific research and new material research, natural disaster assessment, and lightning protection equipment manufacturing.

[0003] In the existing technology, most lightning impulse simulation equipment is fixed in one location and is inconvenient to move. When it needs to be moved to a production workshop or outdoor test site for testing, it needs to be repeatedly installed, adjusted and rewired, which makes the operation of relocating the lightning impulse simulation equipment cumbersome and time-consuming. As a result, when the lightning impulse simulation equipment needs to be temporarily tested or responded to an emergency, it cannot be immediately deployed to a temporary test site or disaster-stricken area, resulting in the inability to provide timely testing support.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The support rod includes a square shell and a square rod. At this time, the stretching rod at the higher position is pulled to drive the blocking block to move out of the blocking slot. At this time, the square shell and square rod at the higher position are in a telescopic state. Since the support rod at the lower position is blocked by the blocking block, it is in a fixed state. At this time, when the rotating rods 1 and 2 rotate, the support plate at the lower position will continue to change the angle against the ground. Since the higher position is not in a fixed state, it will gradually shrink.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] Example 1:

[0032] See also Figures 1-10As shown, a movable lightning impulse simulation device comprises a shell 1; a lightning impulse simulation device is arranged in the shell 1; the bottom end of the outer wall of the shell 1 is rotatably connected to a moving rod 2 and a moving rod 3 through a set of square plates; the outer side walls of the moving rod 2 and the moving rod 3 are fixedly connected to a pair of universal wheels 4; the outer side walls of the moving rod 2 and the moving rod 3 are fixedly connected to a sprocket 5; the pair of sprockets 5 are connected by a chain 6; the outer side wall of the moving rod 2 is fixedly connected to a gear 7; a motor 8 is fixedly connected to one side of the outer wall of the shell 1 through a fixed seat; a rotating shaft 9 is provided at the output end of the motor 8; a gear set 10 is provided on the outer side wall of the rotating shaft 9; the gear set 10 is matched with the gear 7. The lightning impulse simulation device is a prior art and will not be described here. The rotating shaft 9 is driven to rotate, so that the rotating shaft 9 drives the gear set 10 to rotate, and the gear set 10 drives the gear 7 and the moving rod 2 to rotate, because the outer side walls of the moving rod 2 and the moving rod 2 3 are fixedly connected with a sprocket 5; a pair of sprockets 5 are connected by a chain 6, so that the moving rod 2 passes through the sprocket 5, and the chain 6 drives the moving rod 2 3 to rotate, thereby driving a group of universal wheels 4 to rotate, thereby driving the shell 1 and the lightning impulse simulation device in the shell 1 to move, making the lightning impulse simulation device easy to move, and because the lightning impulse simulation device is arranged in the shell 1, there is no need to rewire or repeat the installation after it is moved, thereby saving a lot of time, so that it can be immediately deployed to a temporary test site or disaster-stricken area to provide timely test support.

[0033] The outer wall of the gear set 10 is slidably connected to the outer wall of the rotating shaft 9; one side of the outer wall of the rotating shaft 9 is threadedly connected to a threaded rod 11 through a square block; one end of the outer wall of the threaded rod 11 is rotatably connected to one side of the outer wall of the gear set 10; the opposite sides of the outer wall of the shell 1 are rotatably connected to a rotating rod 12 and a rotating rod 2 13 through a square plate 2; one end of the outer wall of the rotating rod 12 is fixedly connected to a gear 2 14, and the gear 2 14 matches the gear set 10; one side of the outer wall of the shell 1 is rotatably connected to a rotating rod 3 15; the outer walls of the rotating rod 3 15 and the rotating rod 12 are both fixedly connected There is a sprocket 2 16, and a pair of sprockets 2 16 are connected by a chain 2 17; one end of the outer wall of the rotating rod 3 15 and the rotating rod 2 13 is fixed with a gear 3 18, and the pair of gears 3 18 are meshed with each other; the outer side walls of the rotating rod 12 and the rotating rod 2 13 are fixed with a support rod 19; the outer walls of the pair of support rods 19 are rotatably connected to the connecting seat 20 on opposite sides through a pair of round rods; the outer wall bottom ends of the pair of connecting seats 20 are fixed with a support, and by rotating the threaded rod 11, the threaded rod 11 is threadedly connected to the square block, so that the rotation of the threaded rod 11 drives the threaded rod 11 to rotate. Rod 11 moves, so that the threaded rod 11 drives the gear set 10 to move. When the gear set 10 moves to a certain position, the gear set 10 is out of mesh with the gear 1 7 and meshes with the gear 2 14. At this time, when the motor 8 drives the rotating shaft 9 and the gear set 10 to rotate, the gear set 10 drives the gear 2 14 to rotate, and the gear 2 14 drives the rotating rod 12 to rotate. Because the outer walls of the rotating rod 3 15 and the rotating rod 12 are fixed with sprocket 2 16, and a pair of sprockets 2 16 are connected by chain 2 17, the rotating rod 12 is connected through the sprocket 2 16 and chain 2 17 drives the rotating rod three 15 to rotate. Since one end of the outer wall of the rotating rod three 15 and the rotating rod two 13 is fixedly connected with a gear three 18, and the pair of gears three 18 are engaged with each other, the rotating rod three 15 drives the rotating rod two 13 to rotate through the pair of gears three 18, and the rotation direction of the rotating rod two 13 is opposite to that of the rotating rod one 12, so that when the rotating rod one 12 and the rotating rod two 13 rotate, the support rod 19 and the support plate 21 are driven to change their angles until the support plate 21 is against the ground. Since there are support plates 21 on both sides of the shell 1 as auxiliary supports, the shell 1 is more stable when it is moved to a suitable position.

[0034] The gear set 10 includes a main gear 101 and an auxiliary bevel gear 102; one end of the outer wall of the auxiliary bevel gear 102 is fixedly connected to one end of the outer wall of the main gear 101; the top end of the outer wall of the housing 1 is rotatably connected to a reciprocating rod 40 through square plate eight; the bottom end of the outer wall of the reciprocating rod 40 is fixedly connected to bevel gear eight 41, and bevel gear eight 41 and the auxiliary bevel gear 102 are meshed with each other; a reciprocating block 42 is provided on the outer wall of the reciprocating rod 40; one end of the outer wall of the reciprocating block 42 is fixedly connected to a cleaning plate 43, and the inner side wall of the cleaning plate 43 matches the outer side wall of the housing 1. When the gear set 10 moves to a position where it meshes with gear two 14, Because the gear set 10 includes a main gear 101 and an auxiliary bevel gear 102, the auxiliary bevel gear 102 is engaged with the bevel gear eight 41. When the gear set 10 rotates, the bevel gear eight 41 rotates accordingly, thereby driving the reciprocating rod 40 to rotate, so that the reciprocating rod 40 drives the reciprocating block 42 and the cleaning plate 43 to move up and down, cleaning the outer wall of the shell 1, thereby keeping the outside of the shell 1 clean and avoiding affecting the operation of the lightning impulse simulator. Moreover, because the cleaning plate 43 and the support plate 21 operate simultaneously, the operation is further simplified, time is saved, and the efficiency of supporting and cleaning the shell 1 is improved.

[0035] The top end of the outer wall of the support plate 21 is rotatably connected to a rotating rod 28 through square plate three; a group of auxiliary rods 29 are fixed to the outer side wall of the rotating rod 28; one end of the outer wall of the rotating rod 28 is fixed to a worm gear 30; the top end of the outer wall of the support plate 21 is rotatably connected to a worm 31 through square plate four, and the worm 31 and the worm gear 30 are meshed with each other. By rotating the worm 31, the worm 31 and the worm gear 30 are meshed with each other, so that the rotation of the worm 31 drives the worm gear 30 to rotate, and the worm gear 30 drives the rotating rod 28 to rotate, so that the rotation of the rotating rod 28 drives a group of auxiliary rods 29 to change the angle, so that the auxiliary rods 29 are against the ground. At this time, the auxiliary rods 29, the ground and one side of the outer wall of the support plate 21 form a triangle. Due to the stability of the triangle, the auxiliary rods 29 can have The inclined auxiliary rod 29 as part of the supporting structure can disperse the load borne by the support plate 21 to a larger area, thereby reducing the stress concentration in a single part and improving the bearing capacity of the structure. The stability of the angular structure helps to reduce the transmission of vibration, and the inclined auxiliary rod 29 can be adjusted according to the undulations of the terrain, so that the support plate 21 can remain stable on uneven ground. This design improves the adaptability of the supporting structure, enabling it to be used in various complex terrains and environments, and by changing the angle or position of the inclined auxiliary rod 29, the support angle and height of the support plate 21 can be flexibly adjusted to meet the usage requirements in different scenarios.

[0036] The support rod 19 includes a square shell 191 and a square rod 192; the outer side wall of the square rod 192 is slidably connected to the inner side wall of the square shell 191; a group of positioning grooves 22 are provided at the top of the outer wall of the square rod 192; a through groove 23 is provided at the top of the outer wall of the square shell 191; a connecting block 24 is fixedly connected to the top of the outer wall of the square shell 191; a positioning block 25 is fixedly connected to the top of the inner wall of the connecting block 24 through a spring 2; a stretching rod 26 is fixedly connected to the top of the outer wall of the positioning block 25, and the top of the outer wall of the stretching rod 26 passes through the connecting block 24. When the shell 1 is on an uneven ground, because the support rod 19 includes the square shell 191 and the square rod 192, the stretching rod 26 at a higher position is pulled at this time, so that the stretching rod 26 drives the positioning The block 25 moves out of the positioning slot 22. At this time, the square shell 191 and the square rod 192 at the higher position are in a telescopic state. Since the support rod 19 at the lower position is positioned by the positioning block 25, it is in a fixed state. At this time, when the rotating rod 12 and the rotating rod 2 13 rotate, the support plate 21 at the lower position will press against the ground and continue to change the angle. Since the higher position is not in a fixed state, it will gradually shrink. At this time, the support plate 21 at the lower position against the ground will prop up one side of the shell 1, so that the lower side of the shell 1 is parallel to the higher side, so that the shell 1 can be placed in parallel, which is convenient for testing the internal lightning impulse simulation device, so that when the device is placed and installed on an uneven or tilted ground, the shell 1 can also be in a stable state.

[0037] A spring 27 is fixedly connected to one side of the inner wall of the square shell 191, and the other end of the outer wall of the spring 27 is fixedly connected to one end of the outer wall of the square rod 192; the vertical section of the positioning block 25 is in the shape of a right-angled trapezoid; the vertical section of the positioning groove 22 is in the shape of a right-angled trapezoid; the positioning block 25 matches the positioning groove 22 and the through groove 1 23, and the vertical section of the positioning block 25 is in the shape of a right-angled trapezoid; the vertical section of the positioning groove 22 is in the shape of a right-angled trapezoid, and the spring 27 is fixedly connected to one side of the inner wall of the square shell 191, and the other end of the outer wall of the spring 27 is fixedly connected to one end of the outer wall of the square rod 192, so that the square rod 192 It will automatically pop out under the elastic force of spring 1 27, and because the blocking block 25 is in the shape of a right-angled trapezoid, when the square rod 192 pops out, the inclined surface of the blocking slot 22 contacts the inclined surface of the blocking block 25. At this time, the blocking block 25 will gradually move out of the blocking slot 22, making it easy for the square rod 192 to move. When the square rod 192 shrinks, it is blocked by the plane of the blocking block 25, making it impossible to shrink, thereby making it easy for the square rod 192 to stretch. The staff only needs to pull the stretching rod 26 when the square rod 192 shrinks, and there is no need to pull the stretching rod 26 when extending it, thereby simplifying the operation and facilitating operation.

[0038] The bottom end of the outer wall of the support plate 21 is provided with a square through groove 34; the inner side wall of the square through groove 34 is fixedly connected to a pair of expansion plates 35; the top end of the outer wall of the support plate 21 is provided with a through groove 2 36, and the through groove 2 36 is connected to the square through groove 34; the top end of the outer wall of the support plate 21 is rotatably connected to a two-way threaded rod 37 through a square plate 6; the outer side walls of the two-way threaded rod 37 and the rotating rod 28 are fixedly connected to a gear 5 38, and a pair of gears 5 38 are meshed with each other; the outer side wall of the two-way threaded rod 37 is threadedly connected to a pair of threaded blocks 39, and a pair of threaded blocks 39 are fixedly connected to a pair of expansion plates 35 through the through groove 2 36. When the rotating rod 28 rotates, the two-way threaded rod 37 and the outer side walls of the rotating rod 28 are fixedly connected to the gear 5 38 , and a pair of gears 5 38 are engaged with each other, so that the rotation of the rotating rod 28 drives the two-way threaded rod 37 to rotate through the pair of gears 5 38, so that the rotation of the two-way threaded rod 37 drives the pair of threaded blocks 39 to move to both sides at the same time, thereby driving the pair of expansion plates 35 to move to both sides at the same time, thereby increasing the contact area between the support plate 21 and the ground, thereby further increasing the force-bearing area, and further increasing the friction between the support plate 21 and the expansion plate 35 and the ground, so that the stability of the device is further improved. When the auxiliary rod 29 is retracted, the expansion plate 35 is retracted at the same time. Because the expansion plate 35 and the auxiliary rod 29 operate at the same time, the arrangement time of the expansion plate 35 and the auxiliary rod 29 is saved, which effectively saves time.

[0039] The bottom end of the outer wall of the auxiliary rod 29 is in an arc shape; a group of circular grooves 32 are opened on the outer wall of the bottom end of the auxiliary rod 29; a fulcrum rod 33 is fixedly connected to one side of the inner wall of the circular groove 32 through a spring five, and the outer wall of the fulcrum rod 33 is slidably connected to the inner wall of the circular groove 32; one end of the outer wall of the fulcrum rod 33 is in a semicircular shape. When the ground has defects such as potholes, making the ground uneven, the fulcrum rod 33 on the auxiliary rod 29 against the ground will pop out under the elastic force of the spring five. At this time, multiple groups of fulcrum rods 33 will pop out under the elastic force of the spring five. Under the action of the plurality of support rods 33, the plurality of support rods 33 can contact the ground more often due to the positions of the plurality of support rods 33, thereby further increasing the support points of the device, dispersing and transferring the load for the overall structure, thereby enhancing the bearing capacity of the device, and effectively dispersing the load borne by the support plate 21 to a larger area, thereby reducing the stress concentration in a single part and improving the bearing capacity of the structure, while also increasing the friction between the device and the ground, making the device more stable.

[0040] Example 2:

[0041] See also Figure 1-Figure 2 and Figure 5As shown, the outer wall of the shell 1 is fixed with connecting plates 44 on opposite sides; the outer wall tops of the pair of connecting plates 44 are threadedly connected with threaded rods 8 45, and the pair of threaded rods 8 45 respectively penetrate the pair of connecting plates 44; the outer wall bottoms of the pair of threaded rods 8 45 are rotatably connected with square plates 46; the outer wall tops of the pair of square plates 46 are fixed with limiting rods 47, and the pair of limiting rods 47 respectively penetrate the pair of connecting plates 44; the pair of limiting rods 47 are respectively slidably connected to the pair of connecting plates 44, and by rotating the threaded rods 8 45, the threaded rods 8 45 and the connecting plates 44 are threaded. The connection is made, and the connecting plate 44 is in a fixed state, so that the rotation of the threaded rod eight 45 drives the threaded rod eight 45 to move, and the threaded rod eight 45 drives the square plate 46 to move, so that the square plate 46 is against the ground, thereby further improving the supporting force and friction force of the device, making the stability of the device better, and when the shell 1 is on an inclined ground, the support plate 21 on one side is against the ground, so that the shell 1 is stable. At this time, the square plate 46 is against the ground, and also bears part of the load for the support plate 21, thereby effectively reducing the pressure on the support plate 21, making the device safer and more reliable.

[0042] When the present invention is in use, the motor 8 drives the rotating shaft 9 to rotate, so that the rotating shaft 9 drives the gear set 10 to rotate, and the gear set 10 drives the gear 7 and the moving rod 2 to rotate, because the outer side walls of the moving rod 2 and the moving rod 2 3 are fixedly connected with a sprocket 5; a pair of sprockets 5 are connected by a chain 6, so that the moving rod 2 passes through the sprocket 5, and the chain 6 drives the moving rod 2 3 to rotate, thereby driving a group of universal wheels 4 to rotate, thereby driving the shell 1 and the lightning impulse simulation device in the shell 1 to move, making the lightning impulse simulation device easy to move, and because the lightning impulse simulation device is arranged in the shell 1, there is no need to rewire or repeat the installation after it is moved, thereby saving a lot of time, so that it can be immediately deployed to a temporary test site or disaster-stricken area to provide timely test support.

[0043] By rotating the threaded rod 11, since the threaded rod 11 is threadedly connected to the square block, the rotation of the threaded rod 11 drives the threaded rod 11 to move, and the threaded rod 11 drives the gear set 10 to move. When the gear set 10 moves to a certain position, the gear set 10 is disengaged from the gear 1 7 and meshes with the gear 2 14. At this time, when the motor 8 drives the rotating shaft 9 and the gear set 10 to rotate, the gear set 10 drives the gear 2 14 to rotate, and the gear 2 14 drives the rotating rod 12 to rotate. Because the outer walls of the rotating rod 3 15 and the rotating rod 12 are fixed with sprocket 2 16, and a pair of sprockets 2 16 are connected by chain 2 17 They are connected, so that the rotating rod 12 drives the rotating rod 3 15 to rotate through the sprocket 2 16 and the chain 2 17. Since the outer wall ends of the rotating rod 3 15 and the rotating rod 2 13 are fixedly connected with the gear 3 18, and the pair of gears 3 18 are engaged with each other, the rotating rod 3 15 drives the rotating rod 2 13 to rotate through the pair of gears 3 18, and the rotation direction of the rotating rod 2 13 is opposite to that of the rotating rod 1 12, so that when the rotating rod 1 12 and the rotating rod 2 13 rotate, the support rod 19 and the support plate 21 are driven to change their angles until the support plate 21 is against the ground. Since there are support plates 21 on both sides of the shell 1 as auxiliary supports, the shell 1 is relatively stable when it is moved to a suitable position.

[0044] When the shell 1 is on an uneven ground, because the support rod 19 includes a square shell 191 and a square rod 192, the stretching rod 26 at the higher position is pulled, so that the stretching rod 26 drives the blocking block 25 to move out of the blocking slot 22. At this time, the square shell 191 and square rod 192 at the higher position are in a telescopic state. Because the support rod 19 at the lower position is blocked by the blocking block 25, it is in a fixed state. At this time, when the rotating rod 12 and the rotating rod 2 13 rotate, the lower support plate 21 will resist the ground and continue to change its angle. Since the higher one is not in a fixed state, it will gradually shrink. At this time, the support plate 21 at the lower position against the ground will support one side of the shell 1, so that the lower side of the shell 1 is parallel to the higher side, so that the shell 1 can be placed in parallel, which is convenient for the internal lightning impulse simulation device to be tested, so that when the device is placed and installed on an uneven or inclined ground, the shell 1 can also be in a stable state.

[0045] The vertical cross-section of the positioning block 25 is in the shape of a right-angled trapezoid; the vertical cross-section of the positioning groove 22 is in the shape of a right-angled trapezoid, and a spring 27 is fixedly connected to one side of the inner wall of the square shell 191, and the other end of the outer wall of the spring 27 is fixedly connected to one end of the outer wall of the square rod 192, so that the square rod 192 will automatically pop out under the elastic force of the spring 27, and because the positioning block 25 is in the shape of a right-angled trapezoid, when the square rod 192 pops out, the inclined surface of the positioning groove 22 and the inclined surface of the positioning block 25 contact each other. At this time, the positioning block 25 will gradually move out of the positioning groove 22, making the square rod 192 easy to move. When the square rod 192 contracts, it is blocked by the plane of the positioning block 25, so that it cannot contract, thereby making the square rod 192 easy to stretch, so that the staff only needs to pull the stretching rod 26 when the square rod 192 contracts, and there is no need to pull the stretching rod 26 when extending, thereby simplifying the operation and facilitating operation.

[0046] By rotating the worm 31, due to the mutual meshing of the worm 31 and the worm wheel 30, the rotation of the worm 31 drives the worm wheel 30 to rotate, and the worm wheel 30 drives the rotating rod 28 to rotate. The rotation of the rotating rod 28 drives a set of auxiliary rods 29 to change their angles, so that the auxiliary rods 29 are against the ground. At this time, the auxiliary rods 29, the ground, and one side of the outer wall of the support plate 21 form a triangular shape. Due to the stability of the triangle, the auxiliary rods 29 can effectively distribute and transmit loads, thereby enhancing the load-bearing capacity of the device. The inclined auxiliary rods 29, as part of the support structure, can distribute the load borne by the support plate 21 over a larger area, thereby reducing stress concentration in a single part and improving the load-bearing capacity of the structure. The stability of the angled structure helps to reduce the transmission of vibration. The inclined auxiliary rods 29 can be adjusted according to the undulations of the terrain, so that the support plate 21 can remain stable on uneven ground. This design improves the adaptability of the support structure, enabling it to be used in various complex terrains and environments. By changing the angle or position of the inclined auxiliary rods 29, the support angle and height of the support plate 21 can be flexibly adjusted to meet the needs of use in different scenarios.

[0047] When the ground has defects such as potholes, making the ground uneven, the fulcrum rod 33 on the auxiliary rod 29 that is against the ground will pop out under the elastic force of the spring five. At this time, the multiple groups of fulcrum rods 33 will be against the inner wall of the pothole or the uneven ground under the elastic force of the spring five. Due to the position of the multiple groups of fulcrum rods 33, the multiple groups of fulcrum rods 33 can be in contact with the ground more, thereby further increasing the support points of the device, dispersing and transferring the load for the overall structure, thereby enhancing the bearing capacity of the device, and can effectively disperse the load borne by the support plate 21 to a larger area, thereby reducing the stress concentration in a single part, improving the bearing capacity of the structure, and also increasing the friction between the device and the ground, making the device more stable.

[0048] When the rotating rod 28 rotates, since the two-way threaded rod 37 and the outer side wall of the rotating rod 28 are fixedly connected with gear five 38, and the pair of gears five 38 engage with each other, the rotation of the rotating rod 28 drives the two-way threaded rod 37 to rotate through the pair of gears five 38, so that the rotation of the two-way threaded rod 37 drives the pair of threaded blocks 39 to move to both sides at the same time, thereby driving the pair of expansion plates 35 to move to both sides at the same time, thereby increasing the contact area between the support plate 21 and the ground, thereby further increasing the force-bearing area, and also further increasing the friction between the support plate 21 and the expansion plate 35 and the ground, so that the stability of the device is further improved. When the auxiliary rod 29 is retracted, the expansion plate 35 is retracted at the same time. Since the expansion plate 35 and the auxiliary rod 29 operate at the same time, the arrangement time of the expansion plate 35 and the auxiliary rod 29 is saved, which effectively saves time.

[0049] By rotating the threaded rod eight 45, since the threaded rod eight 45 is threadedly connected to the connecting plate 44, and the connecting plate 44 is in a fixed state, the rotation of the threaded rod eight 45 drives the threaded rod eight 45 to move, and the threaded rod eight 45 drives the square plate 46 to move, so that the square plate 46 is against the ground, thereby further improving the supporting force and friction force of the device, making the stability of the device better, and when the shell 1 is on an inclined ground, the support plate 21 on one side is against the ground, making the shell 1 stable, at this time the square plate 46 is against the ground, and also bears part of the load for the support plate 21, thereby effectively reducing the pressure on the support plate 21, making the device safer and more reliable.

[0050] When the gear set 10 moves to the position meshing with the gear 2 14, because the gear set 10 includes the main gear 101 and the auxiliary bevel gear 102, the auxiliary bevel gear 102 is meshing with the bevel gear 8 41. At this time, when the gear set 10 rotates, the bevel gear 8 41 rotates along with it, thereby driving the reciprocating rod 40 to rotate, so that the reciprocating rod 40 drives the reciprocating block 42 and the cleaning plate 43 to move up and down, cleaning the outer wall of the shell 1, so that the outside of the shell 1 remains clean, avoiding affecting the operation of the lightning impulse simulator, and because the cleaning plate 43 and the support plate 21 operate at the same time, the operation is further simplified, time is saved, and the efficiency of supporting and cleaning the shell 1 is improved.
