Description

Technical Field

[0001] This invention belongs to the field of insulator testing devices, and specifically relates to an insulator electrical performance testing device. Background Technology

[0002] Insulators are devices installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. While different types of insulators vary considerably in structure and appearance, they all consist of two main parts: insulating components and connecting hardware. To verify whether an insulator meets its usage requirements, it must undergo mechanical and electrical performance testing before being put into use. However, current technology suffers from poor safety protection in electrical performance testing devices, with inadequate protection for the testing area and after testing. The testing area can be freely entered and touched, and personnel must enter the testing area for assembly before testing and disassembly after testing. Improper operation can easily lead to the testing area becoming electrified or residual electricity causing injury. Furthermore, the removal of insulators after testing depends on personnel following safety procedures, which can also lead to injury from residual electricity carried by the insulator due to negligence or inexperience, causing inconvenience. Summary of the Invention

[0003] (a) Technical problems to be solved To overcome the shortcomings of existing technologies, a device for testing the electrical performance of insulators is proposed. This addresses the issues of poor safety protection in existing insulator testing devices, insufficient protection of the testing area and post-testing areas, unrestricted access to the testing area, and the need for personnel to enter the testing area for assembly before testing and disassembly after testing. Improper operation can easily lead to the testing area becoming electrified or residual electricity causing injury. Furthermore, the removal of insulators after testing depends on personnel following safety procedures, which can also lead to injury due to residual electricity carried by the insulators, causing considerable inconvenience.

[0004] (II) Technical Solution This invention is achieved through the following technical solution: This invention proposes an insulator electrical performance testing device, the structure of which includes a machine base, which is assembled on a base; It also includes an assembly base for assembling insulators, and a traveling mechanism on the base for driving the assembly base to travel on the base. The machine includes a testing area, a test area on one side of the testing area, a discharge area on the other side of the testing area, and a voltage detection area on the side of the discharge area away from the testing area. The traveling mechanism passes through the test area, the testing area, the discharge area, and the voltage detection area. There are doors on both sides of the test area, the testing area, the discharge area, and the voltage detection area. There are door opening restriction devices between the doors on both sides of the test area, the discharge area, and the voltage detection area. The door opening restriction devices are used to prevent the doors on both sides of the test area, the discharge area, and the voltage detection area from being opened simultaneously. The test area is used to prevent the test area from being directly connected to the outside of the machine when the insulator enters the test area.

[0005] The testing area is used for electrical performance testing of insulators. High-definition cameras and ultraviolet imagers are respectively installed on both sides of the testing area perpendicular to the walking mechanism. The high-definition cameras and ultraviolet imagers are isolated from the interior of the testing area by a transparent plate. The discharge zone is used to detect the discharge of the downstream insulator; The voltage testing area is used to detect whether the insulators are energized.

[0006] Furthermore, the insulator can be a single unit or a string of insulators.

[0007] Furthermore, the transparent plate is a highly transparent and insulating material such as insulating glass, polycarbonate plate, epoxy resin plate, polyimide plate, or laminated transparent insulating plate.

[0008] Furthermore, a first electrode is also installed in the detection area, and a detection body and a first telescopic mechanism are installed on the top of the machine base. The first telescopic mechanism is used to drive the first electrode to rise and fall. The detection body is electrically connected to the first electrode. A through hole is provided at the bottom of the detection area. A second telescopic mechanism is installed in the machine base. The second telescopic mechanism is used to drive the second electrode to rise and fall. One end of the second electrode communicates with the detection area through the through hole. The second electrode is located below the first electrode.

[0009] Furthermore, the first electrode is an electrode that is connected to electricity, and the second electrode is a grounding electrode.

[0010] Furthermore, the testing device is an insulation resistance testing device, an impulse voltage generator, or a power frequency withstand voltage testing device, etc.

[0011] Furthermore, the detection area is also equipped with an environmental simulation device, which is used to control the environmental conditions within the detection area. The detection area is also equipped with a collection tank, which is used for the directional discharge of collected debris.

[0012] Furthermore, the environmental simulation device consists of a pump, a pipe with nozzles, and a water tank.

[0013] Furthermore, the assembly base includes a first movable ring, a limiting ring, a base, a second movable ring, a top plate, a limiting rod, and a support plate. A support plate is fixed to one side of the top of the base. A limiting rod is fitted to the top of the support plate with a pin. The top of the limiting rod is fixedly connected to the top plate. A second movable ring is movably fitted through the top plate. A first movable ring is movably fitted through the base. A bottom pin of the insulator is fitted inside the first movable ring. The second movable ring is sleeved on the top of the insulator. Limiting rings are provided on the side end faces of both the first and second movable rings. The limiting rings are used for assembly limiting of the first and second movable rings.

[0014] Furthermore, the first movable ring is a circular ring, and the inner diameter of the first movable ring is larger than the maximum diameter of the second electrode, so that the second electrode can enter the inner ring of the first movable ring.

[0015] Furthermore, the base is also equipped with a deflector bar, the bottom of the first movable ring is lower than the base, and the deflector bar is in contact with the lower part of the outer ring end of the first movable ring.

[0016] Furthermore, the steering rod is a rack, and the tooth surface of the steering rod is assembled facing the first movable ring. The outer ring end of the first movable ring has a tooth groove for the tooth surface of the steering rod to mesh.

[0017] Furthermore, the base is also equipped with a drive mechanism, which is used to drive the walking mechanism to operate.

[0018] Furthermore, the walking mechanism includes a rope and guide wheels. The driving mechanism is an electric rope winder, and there are two driving mechanisms. The guide wheels are mounted on both sides of the top of the base. Each of the two driving mechanisms is connected to one end of a rope. The other ends of the two ropes are guided by the guide wheels and then fixedly connected to both ends of the base. A guide rail is also fixed on the base. The bottom of the mounting base is provided with a track groove that fits with the guide rail. The mounting base slides on the guide rail through the track groove. The guide rail is used to guide the walking mechanism when it drives the mounting base to move.

[0019] Furthermore, both the discharge area and the voltage detection area are equipped with an electrically controlled rotating mechanism. The discharge area is equipped with one or more discharge rods via the electrically controlled rotating mechanism, and the voltage detection area is equipped with an insulator detector via the electrically controlled rotating mechanism. The door is equipped with a door opening and closing mechanism for remote door opening and closing control. The base is equipped with a grounding rod for connecting the grounding grid and the components that need to be grounded.

[0020] Furthermore, the electrically controlled rotating mechanism is a combination of a motor and a rotating rod.

[0021] Furthermore, the door opening and closing mechanism is a hydraulic cylinder or a pneumatic cylinder.

[0022] Furthermore, the door includes a movable plate and a fixed plate. The door opening restriction device includes a locking rod, a locking groove, and a limiting body. The fixed plate is fixed on the machine base and the machine stand. The movable plate has a locking groove on the side adjacent to the fixed plate. The locking rod is located between two adjacent doors. One end of the locking rod is inserted into the locking groove of one door, and the other end of the locking rod is in contact with the movable plate of the other door. The locking rod covers the limiting body, which restricts the locking rod to slide only between the two doors. The connection between the locking groove and the locking rod is a fitted slope, which slopes from the end of the locking rod toward the middle of the locking rod and the movable plate side.

[0023] Furthermore, the locking lever consists of two rods, one end of which is inserted into the slots of two adjacent doors, and the other ends of both rods are located within the limiting mechanism and are separated by a gap. The distance between the gaps is between the depth of a single slot and the depth of two slots, and an elastic element is assembled between the two rods.

[0024] Furthermore, the elastic element is a compression spring.

[0025] Furthermore, a partition is fixed inside the base, which is used to separate different storage areas for storing equipment such as transformers, hydraulic or pneumatic stations, drive mechanisms, and water tanks for environmental simulation.

[0026] Furthermore, it also includes a control console for monitoring and controlling the machine.

[0027] (III) Beneficial Effects One of the above technical solutions has the following advantages or beneficial effects: By setting up a test area, a discharge area, and a voltage detection area on both sides of the detection area, and combining these areas with doors on both sides, along with door-limiting devices to restrict the simultaneous opening of doors on both sides, the devices ensure that when the door of the detection area is opened, the doors of the test area and the discharge area, which are furthest from the detection area, remain closed. This prevents the detection area from directly contacting the outside. Furthermore, the insulators move between areas via a walking mechanism and mounting base, preventing unsafe situations such as unauthorized entry or operation within the detection area. The discharge and voltage detection areas also ensure that the insulators are in a safe contact condition after testing before disassembly. During testing, the insulator's condition is monitored using changes in current and voltage, combined with observations from a high-definition camera and an ultraviolet imager, avoiding direct contact and ensuring safety. This further prevents injuries from live insulators or the detection area. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0030] Example 1: like Figure 1-10 As shown, the present invention provides an insulator electrical performance testing device: its structure includes a machine base 1, which is mounted on a base 5; It also includes an assembly base 4, which is used for assembling the insulator 3. The base 5 is provided with a traveling mechanism 501, which is used to drive the assembly base 4 to travel on the base 5. The machine 1 includes a detection area 7, a test area 6 on one side of the detection area 7, a discharge area 8 on the other side of the detection area 7, and a voltage detection area 9 on the side of the discharge area 8 away from the discharge area 8. The walking mechanism 501 passes through the test area 6, the detection area 7, the discharge area 8, and the voltage detection area 9. There are doors 11 on both sides of the test area 6, the detection area 7, the discharge area 8, and the voltage detection area 9. There are door opening restriction devices 14 between the doors 11 on both sides of the test area 6, the discharge area 8, and the voltage detection area 9. The door opening restriction devices 14 are used to prevent the doors 11 on both sides of the test area 6, the discharge area 8, and the voltage detection area 9 from being opened simultaneously. The test area 6 is used to prevent the test area 7 from being directly connected to the outside of the machine base 1 when the insulator 3 enters the test area 7.

[0031] The detection area 7 is used for electrical performance testing of the insulator 3. A high-definition camera 710 and an ultraviolet imager 711 are respectively installed on both sides of the detection area 7 perpendicular to the walking mechanism 501. The high-definition camera 710 and the ultraviolet imager 711 are isolated from the interior of the detection area 7 by a transparent plate 704. The discharge zone 8 is used to detect the discharge of the rear insulator 3; The voltage testing area 9 is used to detect whether the insulator 3 is energized.

[0032] The insulator 3 can be a single insulator or a string of multiple insulators.

[0033] If the walking mechanism 501 or other structures affect the normal opening and closing of the door 11, a raising or other avoidance structure can be designed at the door 11.

[0034] In use, the mounting base 4 is controlled by the walking mechanism 501 to move to the base 5 located outside the machine 1 on the side of the test area 6. Then, the insulator 3 to be tested is mounted on the mounting base 4. Next, the insulator 3 can be driven into the machine 1 by the walking mechanism 501 for testing. When entering the machine 1, due to the door opening restriction device 14, the door 11 between the test area 6 and the testing area 7 must be closed before the door 11 on the side of the test area 6 away from the testing area 7 can be opened. When the door 11 on the side of the test area 6 away from the testing area 7 is opened, the door opening restriction device 14 will prevent the door 11 between the test area 6 and the testing area 7 from being opened, thus preventing personnel from directly opening it. When the door 11 of the test area 6 is opened, it directly contacts the test area 7. After the mounting base 4 enters the test area 6, the door 11 of the test area 6 away from the test area 7 is closed, and then the door 11 between the test area 6 and the test area 7 is opened, so that the mounting base 4 can drive the insulator 3 into the test area 7 for testing. After testing, the insulator 3 is driven into the discharge area 8 by the mounting base 4. With the same structure as the door 11 of the test area 6 and the door opening restriction device 14, the door 11 of the discharge area 8 can only be opened on one side and closed on the other side. This can prevent contact with the interior of the test area 7 from the discharge area 8, prevent personnel from directly contacting the test area 7, and prevent unsafe situations such as random entry and operation in the test area 7. The setting of the discharge zone 8 away from the detection zone 7 and the voltage testing zone 9 allows the insulator 3 to be discharged through the discharge zone 8 and safely tested through the voltage testing zone 9 after testing, before walking to the base 5 located outside the machine 1 on the side of the voltage testing zone 9 for disassembly. If the voltage testing is not safe, it can be returned to the discharge zone 8 to continue discharging. The structure of the door 11 and the door opening restriction device 14 of the voltage testing zone 9 with the test zone 6 can better prevent the staff from directly contacting the insulator 3 and discharge equipment that may be energized in the discharge zone 8, ensuring that the insulator 3 is in a safe contact condition before testing and disassembly. During testing, the status of the insulator 3 is detected by observing changes in current and voltage in combination with a high-definition camera 710 and an ultraviolet imager 711 for closed-loop detection, avoiding direct contact, ensuring the safety of the device, realizing safe electrical performance testing of the insulator 3, and better preventing the detection zone 7 and the insulator 3 from being energized and causing injury. Finally, the design of isolating the HD camera 710 and the ultraviolet imager 711 from the detection area 7 through the transparent plate 704 ensures the safety of the HD camera 710 and the ultraviolet imager 711, and allows them to be maintained without entering the detection area 7, reducing the need to enter the detection area 7 and improving safety.

[0035] like Figure 1 As shown, in one embodiment, a console 2 is also included, which is used for monitoring and controlling the machine 1.

[0036] like Figure 2 and 7 As shown, in one embodiment, both the discharge zone 8 and the voltage detection zone 9 are equipped with an electrically controlled rotating mechanism 12. One or more discharge rods 801 are mounted in the discharge zone 8 via the electrically controlled rotating mechanism 12. An insulator detector 901 is mounted in the voltage detection zone 9 via the electrically controlled rotating mechanism 12. A door opening and closing mechanism 13 is mounted on the door 11, which is used for remote opening and closing control of the door 11. A grounding rod 16 is mounted inside the base 5, which is used to connect the grounding grid to the components that need to be grounded. The remote control of the discharge rods 801 and the detection of whether the insulator detector 901 is energized via the electrically controlled rotating mechanism 12 ensures the safety of the insulator 3's discharge and energization detection. The remote control of the door opening and closing mechanism 13 also ensures that the device can open and close the door 11 without close-range manual operation.

[0037] like Figure 2 and 7 As shown, in one embodiment, the electrically controlled rotating mechanism 12 is a combination of a motor and a rotating rod.

[0038] like Figure 3 , 7As shown in Figures 9 and 10, in one embodiment, the door opening and closing mechanism 13 is a hydraulic cylinder or a pneumatic cylinder. The hydraulic or pneumatic door opening and closing mechanism can prevent the electrically controlled door from malfunctioning due to the influence of the high-voltage electric field during detection, thus ensuring the safety of remote door opening and closing.

[0039] like Figure 3 , 7 As shown in Figures 9 and 10, in one embodiment, two adjacent regions use the same door 11.

[0040] In one embodiment, two adjacent regions may also employ two or more independent gates 11.

[0041] In one embodiment, the testing body 701 is an insulation resistance testing device, an impulse voltage generator, or a power frequency withstand voltage testing device, etc.

[0042] like Figure 3 , 7 As shown in Figures 9 and 10, in one embodiment, the door opening and closing mechanisms 13 on both sides of the detection area 7 are located on the side of the door 11 away from the detection area 7, which can avoid the arrangement of structures and devices inside the detection area 7, simplify the internal structure of the detection area 7, further reduce the need for maintenance inside the detection area 7, and further improve safety.

[0043] Example 2: like Figure 2 and Figure 3 As shown, compared to Embodiment 1, the detection area 7 in this embodiment is further equipped with a first electrode 703. The top of the machine base 1 is equipped with a detection body 701 and a first telescopic mechanism 702. The first telescopic mechanism 702 is used to drive the first electrode 703 to rise and fall. The detection body 701 is electrically connected to the first electrode 703. The bottom of the detection area 7 is provided with a through hole 708. The base 5 is equipped with a second telescopic mechanism 706. The second telescopic mechanism 706 is used to drive the second electrode 707 to rise and fall. One end of the second electrode 707 communicates with the detection area 7 through the through hole 708. The second electrode 707 is located below the first electrode 703.

[0044] The first electrode 703 is the electrode that is connected to the ground, and the second electrode 707 is the electrode that is grounded.

[0045] When the walking mechanism 501 controls the mounting base 4 to walk to the area below the first electrode 703 in the testing area 7, the first telescopic mechanism 702 can be used to drive the first electrode 703 to descend and contact one end of the insulator 3, and the second telescopic mechanism 706 can be used to drive the second electrode 707 to rise and contact the other end of the insulator 3. Then, the insulator 3 can be tested for insulation, impact resistance, or power frequency withstand voltage by the testing machine body 701. The rest of the structure and effect remain unchanged.

[0046] In one embodiment, the first electrode 703 and the second electrode 707 may also be driven by other power structures to contact the insulator 3 for detection.

[0047] Example 3: like Figure 2 As shown, compared with the previous embodiment, the detection area 7 in this embodiment is also equipped with an environmental simulation device 705, which is used to control the environmental conditions in the detection area 7. The detection area 7 is also provided with a collection tank 709, which is used for the directional discharge of debris after collection.

[0048] When in use, the environmental simulation device 705 can be used to create environments such as fog, rain, and dirt in the detection area 7 to increase the comprehensiveness of the detection. At the same time, it can connect equipment such as debris extraction or recycling to the collection tank 709 so that the debris generated after the simulation can be discharged through the collection tank 709, ensuring the cleanliness of the detection area 7 after the simulation, while the rest of the structure and effect remain unchanged.

[0049] In one embodiment, the environmental simulation device 705 consists of a pump, a pipe with nozzles, and a water tank 17, etc.

[0050] Example 4: like Figure 4 As shown, compared to the previous embodiment, the assembly base 4 in this embodiment includes a first movable ring 401, a limiting ring 402, a base 403, a second movable ring 404, a top plate 405, a limiting rod 406, and a support plate 407. The support plate 407 is fixed to one side of the top of the base 403. The limiting rod 406 is fitted with a pin on the top of the support plate 407. The top of the limiting rod 406 is fixedly connected to the top plate 405. The second movable ring 404 is movably mounted through the top plate 405. The first movable ring 401 is movably mounted through the base 403. The bottom pin of the insulator 3 is fitted inside the first movable ring 401. The second movable ring 404 is sleeved on the top of the insulator 3. The side end faces of the first movable ring 401 and the second movable ring 404 are provided with limiting rings 402. The limiting rings 402 are used for assembly limiting of the first movable ring 401 and the second movable ring 404.

[0051] The first movable ring 401 is a circular ring, and the inner diameter of the first movable ring 401 is larger than the maximum diameter of the second electrode 707, so that the second electrode 707 can enter the inner ring of the first movable ring 401.

[0052] In use, the support plate 407 can be raised by the limiting rod 406 of the pin, and then the bottom pin of the insulator 3 can be installed in the first movable ring 401 of the base 403. Then the top plate 405 can be lowered so that the second movable ring 404 can be sleeved on the top of the insulator 3, thus achieving quick and stable assembly of the insulator 3. When disassembling, only the top plate 405 needs to be raised, which can achieve quick assembly and disassembly of the insulator 3, while the rest of the structure and effect remain unchanged.

[0053] like Figure 2 As shown, in one embodiment, the base 5 is also equipped with a reversing rod 10. The bottom of the first movable ring 401 is lower than the base 403. The reversing rod 10 is in contact with the lower part of the outer ring end of the first movable ring 401. Combined with the setting of the movable ring, when the reversing rod 10 contacts the first movable ring 401, the movement of the mounting base 4 will cause the insulator 3 to rotate due to the friction force received by the first movable ring 401 or the contact surface structure. This facilitates the rotation observation, discharge and voltage detection of the insulator, and prevents the blind spot problem of the high-definition camera 710 and the ultraviolet imager 711 in closed observation.

[0054] In one embodiment, the reversing rod 10 is a rack, and the tooth surface of the reversing rod 10 is assembled facing the first movable ring 401. The outer ring end of the first movable ring 401 has a tooth groove for meshing with the tooth surface of the reversing rod 10, so as to ensure that after the reversing rod 10 contacts the first movable ring 401, the mounting base 4 can stably drive the insulator 3 to rotate when it moves.

[0055] Example 5: like Figure 2 As shown, compared with the previous embodiment, the deflector 10 in this embodiment is a whole rod that runs through the test area 6, the detection area 7, the discharge area 8 and the voltage detection area 9, so that the deflector 10 can be directly pulled out from outside the machine 1 for replacement or maintenance without entering each area, further improving the safety and convenience of device replacement or maintenance, while the rest of the structure and effect remain unchanged.

[0056] like Figure 3 As shown, in one embodiment, the deflector 10 is provided with a clearance groove 1001 in the area between the second electrode 707 and the first electrode 703. The clearance groove 1001 is used to disengage the deflector 10 from contact with the first movable ring 401, so as to prevent the insulator 3 from being in a rotating state when in contact with the second electrode 707 and the first electrode 703, thus avoiding wear on the second electrode 707 and the first electrode 703 and ensuring the safety of the detection.

[0057] Example 6: like Figure 10As shown, compared with the previous embodiment, the directional rod 10 in this embodiment is a multi-rod structure. The multi-rod structure 10 is respectively assembled on the base 5 when the first movable ring 401 needs to be rotated, so that the directional rod 10 is completely located inside the machine base 1. Although this increases the inconvenience of maintenance, it can avoid contact with the outside and can better ensure that the insulator 3 rotates only in the designated area, while the rest of the structure and effect remain unchanged.

[0058] Example 7: like Figure 2 As shown, compared with the previous embodiment, the base 5 in this embodiment is further provided with a drive mechanism 503, which is used to drive the walking mechanism 501 to operate.

[0059] Example 8: like Figure 2 As shown, compared to the previous embodiment, the walking mechanism 501 in this embodiment includes a rope 50101 and a guide wheel 50102. The driving mechanism 503 is an electric rope winder. There are two driving mechanisms 503. The guide wheels 50102 are mounted on the top two sides of the base 5. Each of the two driving mechanisms 503 is connected to one end of a rope 50101. The other ends of the two ropes 50101 are guided by the guide wheels 50102 and fixedly connected to both ends of the base 403. A guide rail 504 is also fixed on the base 5. The bottom of the mounting base 4 is provided with a track groove 408 that fits with the guide rail 504. The mounting base 4 slides on the guide rail 504 through the track groove 408. The guide rail 504 is used to guide the walking mechanism 501 when it drives the mounting base 4 to walk. By using the rope 50101 and the guide rail 504, it is convenient for the mounting base 4 to walk back and forth on the base 5. The rest of the structure and effect remain unchanged.

[0060] Example 9: like Figure 5 As shown, compared with the previous embodiment, the door 11 in this embodiment includes a movable plate 1101 and a fixed plate 1102. The door opening restriction device 14 is a purely mechanical linkage mechanism, which can avoid the situation where the electric linkage is easily damaged by the high voltage and magnetic field of the detection area 7, and ensure the service life and safety. The rest of the structure and effect remain unchanged. like Figure 5As shown, in one embodiment, the door opening restriction device 14 includes a locking rod 1401, a slot 1402, and a limiting body 1405. The fixed plate 1102 is fixed to the base 5 and the base 5. The movable plate 1101 has a slot 1402 on the side adjacent to the fixed plate 1102. The locking rod 1401 is disposed between two adjacent doors 11. One end of the locking rod 1401 is inserted into the slot 1402 of one door 11, and the other end of the locking rod 1401 is attached to the movable plate 1101 of the other door 11. The locking rod 1401 covers the limiting body 1405, and the limiting body 1405 is used to restrict the opening of the door. The rod 1401 can only slide between the two doors 11. The groove 1402 and the rod 1401 are connected by a beveled surface. The beveled surface slopes from the end of the rod 1401 toward the middle of the rod 1401 and the movable plate 1101. When one door 11 is opened, the groove 1402 of one door 11 will drive the rod 1401 to slide into the groove 1402 of the other door 11. If the rod 1401 cannot slide into the groove 1402 of the other door 11, it is determined that the other door 11 is not completely closed, which will cause the door 11 on the opening side to be unable to open, thus realizing a mechanical linkage structure that allows only one side of the door 11 to be opened.

[0061] like Figure 5 As shown, in one embodiment, a limiting plate 1403 is also fixed on the locking rod 1401. The limiting plate 1403 and the limiting body 1405 are equipped with an elastic element 1404. The elastic element 1404 is used to fix the locking rod 1401 in the slot 1402 on one side when it is in the free state. By setting the elastic element 1404 and the limiting plate 1403, the locking rod 1401 is always inserted in the slot 1402 of the side door 1 of the detection area 7 when it is in the free state, ensuring that the characteristic area door 11 is in the locked state and improving safety.

[0062] In one embodiment, the elastic element 1404 is a compression spring.

[0063] like Figure 5 As shown in the left slot 1402, in one embodiment, when two adjacent areas can use the same door 11, some areas will be in the case where the slot 1402 of the movable plate 1101 is located on the other side of the fixed plate 1102. At this time, the fixed plate 1102 is provided with a passage slot 110201 for the passage of the locking rod 1401.

[0064] Example 10: like Figure 6As shown, compared to Embodiment Nine, the locking lever 1401 in this embodiment uses two levers. One end of each lever is pinned into the slots 1402 of two adjacent doors 11, and the other ends of both levers are located within the limiting body 1405 with a gap 1406 between them. The distance between the gap 1406 is between the depth of a single slot 1402 and the depth of two slots 1402. An elastic element 1404 is assembled between the two levers. Therefore, the locking lever 1401 does not need to be fitted with a limiting plate 1403 and an elastic element 1404. In use, the two levers of the locking lever 1401 can always be pinned into the slots 1402 of two adjacent doors 11, ensuring that the doors 11 are in a temporary locked state and preventing the doors 11 from sliding arbitrarily. The mechanism is such that, because the spacer groove 1406 between the two rods is located between the depth of a single slot 1402 and the depth of both slots 1402, when one door 11 is opened, one rod of the latch 1401 moves within the slot 1402 and compresses the elastic element 1404 between the two rods, keeping the other rod in contact with the latch 1402 of the other door 11. If the other rod is not in the slot 1402 of the other door 11, the spacer groove 1406 is already occupied, which prevents the rod of the latch 1401 on the opening side from disengaging from or completely disengaging from the slot 1402 of the door 11 on the contact side. This ensures that the two adjacent doors 11 cannot be opened, achieving mechanical linkage and improving safety, while the rest of the structure and effect remain unchanged.

[0065] Example 11: like Figure 2 As shown, compared with the previous embodiment, the base 5 in this embodiment is fixed with a partition 502. The partition 502 is used to separate different storage areas for storing equipment such as transformer 18, power station 15, drive mechanism 503 and water tank 17 for environmental simulation, so as to facilitate the independent hiding and protection of auxiliary equipment. The rest of the structure and effect remain unchanged.

[0066] Example 12: In one embodiment, the transparent plate 704 is a highly transparent and insulating material such as insulating glass, polycarbonate plate, epoxy resin plate, polyimide plate or laminated transparent insulating plate, so that the high-definition camera 710 and ultraviolet imager 711 can see and detect the situation in the detection area 7 while ensuring safety, and the rest of the structure and effect remain unchanged.

[0067] Example 13: Compared to the previous embodiments, in this embodiment, the machine platform 1, machine base 5, deflector rod 10, door 11, electrically controlled rotation mechanism 12, door opening and closing mechanism 13, door opening restriction device 14, walking mechanism 501, partition 502, guide rail 504, first telescopic mechanism 702, transparent plate 704, environmental simulation device 705, and second telescopic mechanism 706 are all made of insulating materials to prevent leakage. The rest of the structure and effect remain unchanged.
