[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-13As shown, a traffic light fault detection system for the Internet of Things includes a traffic light assembly assembled on a rod body 1. A trigger rod 8 is hingedly provided in the rod body 1. An electromagnet 77 fixedly mounted in the rod body 1 and magnetically engaged with an iron plate 83 provided on one side of the trigger rod 8. A torsion spring 81 provided on the trigger rod 8 stores force when the electromagnet 77 is magnetically attracted to the iron plate 83. A main wire 71 for supplying power to the electromagnet 77 is provided in the rod body 1.

[0036] It also includes a contact plate 74 and a main contact plate 75 and an auxiliary contact plate 76 arranged on both sides thereof. The battery pack 73 and the auxiliary contact plate 76 arranged in the rod body 1 are electrically connected. The main contact plate 75 maintains a passage with the main wire 71 and the traffic light group respectively when the electromagnet 77 magnetically attracts the iron plate 83. When the electromagnet 77 is powered off and stops magnetic attraction, the torsion spring 81 releases the stored force to allow the auxiliary contact plate 76 and the traffic light group to pass through.

[0037] Specifically, it also includes a transmission plate 82 fixedly mounted on the first end of the trigger rod 8 and a transposition groove 85 opened at the second end of the trigger rod 8. A main circuit board 84 is provided on one side of the second end of the trigger rod 8. The inner walls on both sides of the transposition groove 85 are fixedly mounted with a first contact plate 86 and a second contact plate 87, respectively. The first contact plate 86 and the second contact plate 87 are respectively electrically connected to the main circuit board 84. The top end of the electric shock plate 74 is movably arranged in the transposition groove 85. The torsion spring member 81 is sleeved on the hinge shaft of the trigger rod 8, and the two ends of the torsion spring member 81 are respectively fixedly mounted on the trigger rod 8 and the rod body 1. The electric shock plate 74 is fixedly mounted on the support frame 7. The traffic light group, the transmission plate 82, and the main circuit board 84 are respectively electrically connected.

[0038] A support frame 7 is fixedly installed in the pole body 1, and the main wire 71 and the battery pack 73 are fixedly installed on the support frame 7 respectively. A charging controller 72 is fixedly installed on the support frame 7, which is electrically connected to the main wire 71 and the battery pack 73 respectively. By utilizing the charging controller 72, the main wire 71 can charge the battery pack 73 when powered on. The charging controller 72 has the effect of reducing voltage and rectifying. The charging controller 72 is a well-known technical means for those skilled in the art and will not be described here.

[0039] Furthermore, when the main wire 71 is normally powered, the electromagnet 77 is energized to magnetically attract the iron plate 83, thereby flipping the trigger rod 8 and storing force in the torsion spring 81. At the same time, the trigger rod 8 flips to make the first contact plate 86 fit onto the main contact plate 75. At this time, the electricity of the main wire 71 acts on the main circuit board 84 along the main contact plate 75 and the first contact plate 86, and then under the action of the rectifier circuit and the control circuit provided on the main circuit board 84, the electricity and control signal on the main circuit board 84 act on the traffic light group along the transmission plate 82, thereby energizing the traffic light group and lighting it up.

[0040] Furthermore, when the main power line 71 is de-energized due to ground construction damage or other reasons, the electromagnet 77 loses power and stops the magnetic iron plate 83. At this time, the torsion spring 81 releases its stored force to drive the trigger lever 8 to flip and reset. The second contact plate 87 on the trigger lever 8 then contacts the auxiliary contact plate 76 on the contact plate 74. At this time, the battery pack 73 provides power. The electricity from the battery pack 73 then acts on the main circuit board 84 along the auxiliary contact plate 76 and the second contact plate 87. The electricity from the main circuit board 84 and the control signal then act on the traffic light assembly along the transmission plate 82, thereby energizing the traffic light assembly and illuminating it. Thus, when the main power line 71 stops supplying power, the battery pack 73 continues to provide power to illuminate the traffic light assembly, thereby ensuring the normal operation of the traffic light assembly during the short period of power outage of the main power line 71, thereby maintaining normal traffic order for a short period of time.

[0041] In order to promptly detect and report a fault in the main line 71, when the main line 71 is de-energized to stop the electromagnet 77 from magnetically attracting the main line 71, the torsion spring 81 releases its stored force to cause the trigger lever 8 to flip and reset. The second contact plate 87 on the trigger lever 8 then contacts the auxiliary contact plate 76 on the contact plate 74, thereby allowing the battery pack 73 to supply power. Therefore, a network unit electrically connected to the second contact plate 87 can be provided on the main circuit board 84. When the second contact plate 87 supplies power, the 3G / 4G / 5G signal in the network unit is used to feed back circuit information, thereby promptly detecting a fault in the main line 71. Currently available signal light system fault monitoring and acquisition terminals on the market can monitor the status of signal lights in real time. Therefore, when the terminal device detects that the signal light is abnormally powered, if the feedback signal from the network unit on the main circuit board 84 is collected, it is determined that the main line 71 is abnormally powered. If the feedback signal from the network unit on the main circuit board 84 is not collected, and the terminal device detects that the signal light is abnormally powered, it can be determined that the main circuit board 84 has a fault. Therefore, by turning over the trigger rod 8 and coordinating the magnetic attraction between the electromagnet 77 and the iron plate 83, the signal light fault detection is achieved.

[0042] The transmission and application of 3G / 4G / 5G signals in the network unit and the traffic light system fault monitoring and collection terminal are all existing technologies and are well-known technical means to those skilled in the art, so they will not be elaborated here.

[0043] In the above technical solution, the electromagnet 77 is used to attract the iron plate 83 so that the main wire 71 can normally supply power to the traffic light group. When the power supply of the main wire 71 is abnormal, the torsion spring member 81 releases the stored force to reset the trigger rod 8, thereby allowing the battery pack 73 to supply power to the traffic light group, so that the traffic light group can operate normally in a short time, thereby ensuring the operation of traffic.

[0044] As an embodiment further provided by the present invention, the traffic light group includes three lamp assemblies, and the lamp assembly includes a substrate 5 and small lamp units 52 arranged in a circular array thereon, the small lamp units 52 include two groups of first light strips 53 and one group of second light strips 54, when the electromagnet 77 magnetically attracts the iron plate 83, the main wire 71 is electrically connected to the small lamp units 52 respectively, and when the iron plate 83 is separated from the electromagnet 77, the second light strip 54 and the battery pack 73 are connected.

[0045] Specifically, the three lamp assemblies correspond to the red, green and yellow lights of the signal light respectively. By making the two groups of first light strips 53 and the group of second light strips 54 in the lamp assembly electrically connected to the transmission plate 82 on the trigger rod 8, when the main wire 71 is de-energized to stop the electromagnet 77 from magnetic attraction, the torsion spring 81 releases the stored force to drive the trigger rod 8 to flip and reset, and then the second contact plate 87 on the trigger rod 8 contacts the auxiliary contact plate 76 on the contact plate 74, so that the electricity on the battery pack 73 is transmitted to the main circuit board 84 along the auxiliary contact plate 76 and the second contact plate 87. By utilizing the corresponding control program and circuit switch set on the main circuit board 84, the electric energy flowing from the second contact plate 87 to the main circuit board 84 is controlled to flow solely to the second light strip 54 in the lamp assembly, so that the second light strip 54 is lit. At this time, the lamp assembly continues to illuminate and guide through the illumination of the second light strip 54. Compared with the two groups of first light strips 53 and one group of second light strips 54 lighting up at the same time, the battery pack 73 is used to power only the second light strips 54, thereby achieving the continuous operation of the signal light while extending the service life of the signal light.

[0046] The arrangement of corresponding control circuits, current detection and control programs on the main circuit board 84 is a control technical means for those skilled in the art and will not be elaborated here.

[0047] As another embodiment provided by the present invention, it includes a first vertical plate 91 and a second vertical plate 92 fixedly installed in the rod body 1, and the top end of the trigger rod 8 is movably arranged between the first vertical plate 91 and the second vertical plate 92. A middle plate 94 electrically connected to the two groups of first light strips 53 is fixedly installed on the first vertical plate 91, and a lower plate 95 electrically connected to a group of second light strips 54 is fixedly installed on the first vertical plate 91 and the second vertical plate 92 respectively. When the iron plate 83 breaks away from the electromagnet 77, the trigger rod 8 breaks away from the first vertical plate 91 and adheres to the second vertical plate 92.

[0048] Specifically, a fixed plate 9 is fixedly installed in the rod body 1, and the first vertical plate 91 and the second vertical plate 92 are respectively fixedly installed on the fixed plate 9, and an upper plate 93 is also fixedly installed on the first vertical plate 91, and the center light 55 fixedly installed on the base plate 5 is electrically connected to the upper plate 93, the first light strips 53 in the three light assemblies are respectively electrically connected to the middle plate 94; the second light strips 54 in the three light assemblies are respectively electrically connected to the lower plate 95; the center lights 55 in the three light assemblies are respectively electrically connected to the upper plate 93.

[0049] When the main wire 71 is powered normally, the electromagnet 77 is energized to magnetically attract the iron plate 83, thereby flipping the trigger lever 8 and storing force in the torsion spring 81. At the same time, the trigger lever 8 flips to make the first contact plate 86 fit on the main contact plate 75, and the transmission plate 82 on the trigger lever 8 fits on the upper plate 93, the middle plate 94 and the lower plate 95 on the first vertical plate 91. At this time, the electricity of the main wire 71 acts on the main circuit board 84 along the main contact plate 75 and the first contact plate 86, and then under the action of the rectifier circuit and the control circuit provided on the main circuit board 84, the main circuit The electrical and control signals on the board 84 act on the upper board 93, the middle board 94 and the lower board 95 along the transmission board 82, thereby controlling the operation of the center light 55, the first light strip 53 and the second light strip 54 to light up at the same time. In order to be able to distinguish the electrical signals emitted by the main circuit board 84, a corresponding receiving end is set on the substrate 5 serving as a circuit board to analyze and calculate the electrical signals emitted by the main circuit board 84, thereby controlling whether the lights on the substrate 5 are on. The receiving signals, signal processing and signal calculation are well-known technical means for those skilled in the art and will not be elaborated here.

[0050] When the main power line 71 is de-energized, causing the electromagnet 77 to cease magnetic attraction, the torsion spring 81 releases its stored force, causing the trigger lever 8 to flip and reset. Simultaneously, the tip of the trigger lever 8 breaks free from the first vertical plate 91 and rests on the second vertical plate 92. This causes the transmission plate 82 to contact the lower plate 95 on the second vertical plate 92. The second contact plate 87 on the trigger lever 8 then contacts the auxiliary contact plate 76 on the contact plate 74, allowing electricity from the battery pack 73 to be transmitted along the auxiliary contact plate 76 and the second contact plate 87 to the main circuit board 84. After data processing by the main circuit board 84, it is transmitted to the transmission plate 82. The electrical signal from the transmission plate 82 is then transmitted along the lower plate 95 on the second vertical plate 92 to the base plates 5 in each of the three lamp assemblies. After processing by the base plates 5, the signals are used to control whether the second light strip 54 illuminates. Therefore, when the main power line 71 is de-energized, the flipping of the trigger lever 8 and the triggering of the signal only on the lower plate 95 illuminate only the second light strip 54. By reducing the lighting of the central lamp 55 and the lamp bodies of the first lamp strip 53 , electric energy is saved.

[0051] As another embodiment provided by the present invention, the lamp assembly includes a single-opening protective cover 3 and an inner sleeve 4 inserted into the single-opening protective cover 3. The inner wall of the inner sleeve 4 is fixedly installed with a lining plate 41 for placing the substrate 5. When the inner sleeve 4 is attached to the inner wall of the single-opening protective cover 3, the substrate 5 is attached to the lining plate 41.

[0052] Specifically, the backing plate 41 is provided with a first metal plate 56, a second metal plate 57, and a third metal plate 58. The first metal plate 56 is electrically connected to a first wire 66, the second metal plate 57 is electrically connected to a second wire 67, and the third metal plate 58 is electrically connected to a third wire 68. The first wires 66 are electrically connected to one another, the second wires 67 are electrically connected to one another, and the third wires 68 are electrically connected to one another. The first ends of the third wires 68 are electrically connected to the two lower plates 95, the first ends of the second wires 67 are electrically connected to the middle plate 94, and the first ends of the first wires 66 are electrically connected to the upper plate 93. When the base plate 5 is placed on the backing plate 41, the terminals connected to the first light strips 53 on the base plate 51 are in contact with the second metal plate 57, the terminals connected to the second light strips 54 are in contact with the third metal plate 58, and the terminals connected to the center light 55 are in contact with the first metal plate 56. As a result, the center light 55, first light strip 53, and second light strip 54 on the base plate 5 are electrically connected to the upper plate 93, the middle plate 94, and the lower plate 95, respectively, through the action of the first metal plate 56, the second metal plate 57, and the third metal plate 58, as well as the first wire 66, the second wire 67, and the third wire 68. The single-opening shield 3 is a hard transparent plastic sleeve. An extension rod 11 is fixedly mounted on one side of the top end of the rod body 1, and a mounting housing 2 is fixedly mounted on the end of the extension rod 11. The mounting housing 2 has a through-slot 21 formed therein, and the single-opening shield 3 is fixedly mounted in each of the through-slots 21.

[0053] The base plate 5 is placed on the backing plate 41, with the terminals connected to the multiple first light strips 53 on the base plate 5 in contact with the second metal plate 57, the terminals connected to the multiple second light strips 54 in contact with the third metal plate 58, and the terminals connected to the center light 55 in contact with the first metal plate 56. The inner sleeve 4 is then manually inserted into the single-opening shield 3. This forces the base plate 5 to move closer to the inner wall of the single-opening shield 3. The inner wall of the single-opening shield 3 and the backing plate 41 cooperate to clamp the base plate 5, ensuring a tighter fit on the backing plate 41. When the center light 55, first light strips 53, and second light strips 54 on the base plate 5 illuminate and generate heat, the heat is transferred to the backing plate 41. This heat is then dissipated along the side of the backing plate 41 facing the base plate 5. Compared to conventional signal lights enclosed within a housing, the base plate 5 adhered to the backing plate 41 allows for faster heat dissipation, thereby reducing the risk of circuit aging caused by excessive heat.

[0054] As another embodiment provided by the present invention, a sealing rubber airbag 61 is fixedly installed at one end of the inner sleeve 4 close to the inner wall of the single-opening protective cover 3. When the inner sleeve 4 is close to the inner wall of the single-opening protective cover 3, the sealing rubber airbag 61 is squeezed and deformed to cover the substrate 5.

[0055] Specifically, horizontal platforms 51 arranged in a linear array are fixedly mounted on the base plate 5 , and the first light strip 53 and the second light strip 54 are respectively fixedly mounted on the horizontal platforms 51 . Meanwhile, connecting rings 59 are respectively fixedly mounted on the multiple horizontal platforms 51 .

[0056] Furthermore, by placing the substrate 5 on the lining plate 41, and then manually pushing the inner sleeve 4 to be inserted into the single-opening protective cover 3, the sealing rubber airbag 61 gradually approaches the inner wall of one side of the single-opening protective cover 3, and then the end of the inner sleeve 4 and the inner wall of the single-opening protective cover 3 are squeezed together to expand the sealing rubber airbag 61, and the expanded part of the sealing rubber airbag 61 squeezes and blocks the connecting ring 59. At this time, under the squeezing and blocking of the sealing rubber airbag 61, the substrate 5 is more closely attached to the lining plate 41, and at the same time is limited to the lining plate 41 by the sealing rubber airbag 61. Because the sealing rubber airbag 61 is attached to the single-opening protective cover 3, the sealing rubber airbag 61 is used to seal the inner sleeve 4 and the single-opening protective cover 3, so that the substrate 5 is in a sealed environment, providing a good use environment for the lights and circuits on the substrate 5.

[0057] As the optimal embodiment provided by the present invention, a gripping rod 43 is fixedly installed on the inner wall of the inner sleeve 4, and a locking rod 62 that slides inside the gripping rod 43 is symmetrically provided on the outer wall of the inner sleeve 4, and the first end of the locking rod 62 is movably provided in the slot 32 opened on the inner wall of the single-opening shield 3.

[0058] Specifically, the first end of the locking rod 62 is provided with a curved angle, the inner wall of the single-opening shield 3 is provided with a guide slide 31, and the card slot 32 is provided on the inner wall of the guide slide 31, and the main spring 63 is fixedly installed on the locking rod 62, and the first end of the main spring 63 is fixedly installed on the inner sleeve 4.

[0059] Furthermore, by placing the base plate 5 on the lining plate 41, and then manually grasping the grasping rod 43 and pushing it to make the inner sleeve 4 inserted into the single-opening protective cover 3, by sliding the locking rod 62 protruding from the inner sleeve 4 along the guide slide 31, and then the curved angle on the locking rod 62 and the single-opening protective cover 3 are squeezed to compress the main spring 63 to store force, as the inner sleeve 4 moves, the end of the inner sleeve 4 and the inner wall of the single-opening protective cover 3 are squeezed together to expand the sealing rubber airbag 61. At this time, the expanded part of the sealing rubber airbag 61 squeezes and blocks the connecting ring 59. Because the sealing rubber airbag 61 is attached to the single-opening protective cover 3, the sealing rubber airbag 61 is used to seal the inner sleeve 4 and the single-opening protective cover 3. Then the main spring 63 releases the stored force to push the locking rod 62. At this time, the first end of the locking rod 62 is inserted into the card slot 32 to lock the inner sleeve 4 on the single-opening shield 3. Therefore, the cooperation between the locking rod 62 and the main spring 63 can achieve the quick installation and fixation of the inner sleeve 4 and the base plate 5 thereon.

[0060] As another embodiment provided by the present invention, a U-shaped pressure rod 65 is slidably provided on the locking rod 62, and both ends of the U-shaped pressure rod 65 slide on the inclined groove surface 64 opened on the locking rod 62 to simultaneously disengage the first end of the locking rod 62 from the slot 32.

[0061] Specifically, the two ends of the U-shaped pressure rod 65 slide on the inclined groove surface 64 respectively, and then after the worker grasps and fixes the grasping rod 43, the U-shaped pressure rod 65 is pressed close to the grasping rod 43. At this time, the two ends of the U-shaped pressure rod 65 slide on the inclined groove surface 64 opened on the locking rod 62 to simultaneously disengage the first end of the locking rod 62 from the slot 32. At this time, the inner sleeve 4 and the single-opening protective cover 3 are unlocked, so that the inner sleeve 4 can be quickly removed from the single-opening protective cover 3.

[0062] As another embodiment provided by the present invention, the outer wall of the inner sleeve 4 is fixedly mounted with an alignment airbag 6 located on one side of the sealing rubber airbag 61, and the sealing rubber airbag 61 and the curved surface portion 33 set on the inner wall of the single-opening protective cover 3 are engaged with each other to deform and extrude the alignment airbag 6.

[0063] Specifically, the outer wall of the inner sleeve 4 is provided with a support ring 42, and the alignment airbag 6 is located between the support ring 42 and the sealing rubber airbag 61. The substrate 5 is placed on the lining plate 41, and then the inner sleeve 4 is manually pushed to be inserted into the single-opening protective cover 3. The locking rod 62 protruding from the inner sleeve 4 is slid along the guide slide 31, and then the curved angle on the locking rod 62 and the single-opening protective cover 3 are squeezed to compress the main spring 63 to store force. As the inner sleeve 4 moves, the end of the inner sleeve 4 and the inner wall of the single-opening protective cover 3 are squeezed together to expand the sealing rubber airbag 61. At this time, the expanded part of the sealing rubber airbag 61 squeezes and blocks the connecting ring 59. Because the sealing rubber airbag 61 is attached to the single-opening protective cover 3, the sealing rubber airbag 61 is used to seal the inner sleeve 4 and the single-opening protective cover 3. At the same time, a portion of the sealing rubber bladder 61 is deformed by the curved surface 33 on the inner wall of the single-opening shield 3. The deformed sealing rubber bladder 61 then flips over onto the alignment bladder 6. The restraining action of the inner wall of the single-opening shield 3 compresses and covers the alignment bladder 6, thereby increasing the contact surface between the sealing rubber bladder 61 and the alignment bladder 6 and further enhancing the seal against the substrate 5. Furthermore, the alignment bladder 6 is located outside the inner sleeve 4, reducing the radiation exposure of the alignment bladder 6 to the lamp body on the substrate 5, thereby slowing down the aging and hardening of the alignment bladder 6 and prolonging the seal against the substrate 5. The main spring 63 then releases its accumulated force to push against the locking lever 62. The first end of the locking lever 62 then engages the slot 32, locking the inner sleeve 4 to the single-opening shield 3. Thus, the cooperation between the locking lever 62 and the main spring 63 allows for the rapid installation and securement of the inner sleeve 4 and the substrate 5 thereon.

[0064] As another embodiment further provided by the present invention, a clamping plate group arranged in a circular array is provided on the lining plate 41, and the clamping plate group includes symmetrically arranged main elastic plates 44 and push plates 45 slidably arranged between the two main elastic plates 44. The push plates 45 slide to push the main elastic plates 44 to deform and fit onto the side walls of the horizontal platform 51 provided on the base plate 5.

[0065] Specifically, the first end of the main elastic plate 44 is fixedly mounted on the lining plate 41. In order to further fix the substrate 5 and avoid the problem of poor contact between the substrate 5 and the lining plate 41 caused by the shaking of the rod body 1 due to natural factors, when the substrate 5 is placed on the lining plate 41, the horizontal platform 51 is located between each two clamping plate groups, and then a plurality of push plates 45 are slid to push the two main elastic plates 44 with the push plates 45. At this time, the two main elastic plates 44 are opened and flipped over to fit on the horizontal platform 51 respectively. The horizontal platforms 51 are squeezed and limited by using a plurality of main elastic plates 44 and push plates 45 to fix them, so that the substrate 5 is stably placed on the lining plate 41.

[0066] The way in which the multiple push plates 45 slide simultaneously can be by sliding multiple sliders on the inner sleeve 4 and respectively sliding with the single-opening shield 3 to push the push plates 45 to slide; or by expanding the sealing rubber airbag 61 or the positioning airbag 6 to push the multiple push plates 45 to slide; or any other method known to those skilled in the art to control the simultaneous sliding of the multiple push plates 45 is available.

[0067] As a further optimal embodiment provided by the present invention, it also includes extrusion blocks 46 slidably arranged in the inner sleeve 4 and corresponding to the clamping plate groups respectively, and the extrusion blocks 46 are expanded and squeezed by the positioning airbag 6 to slide and push the push plate 45.

[0068] Specifically, resetting elastic plates 47 are provided on both sides of the extrusion block 46 in the inner sleeve 4. The first end of the resetting elastic plates 47 is fixedly mounted on the inner sleeve 4, and the second end of the resetting elastic plates 47 pushes against the extrusion block 46 to make the extrusion block 46 fit on the alignment airbag 6. The push plate 45 is fixedly mounted on the extrusion block 46.

[0069] The base plate 5 is placed on the backing plate 41, with the terminals connected to the plurality of first light strips 53 contacting the second metal plate 57, the terminals connected to the plurality of second light strips 54 contacting the third metal plate 58, and the terminals connected to the center light 55 contacting the first metal plate 56. The inner sleeve 4 is then manually inserted into the single-opening protective cover 3. The locking rod 62 protruding from the inner sleeve 4 slides along the guide rail 31, and the curved angle of the locking rod 62 and the single-opening protective cover 3 compress the main spring 63 to accumulate force. As the inner sleeve 4 moves, the end of the inner sleeve 4 and the inner wall of the single-opening protective cover 3 are pressed together, causing the sealing rubber airbag 61 to expand. The expanded portion of the sealing rubber airbag 61 compresses and blocks the connecting ring 59. Because the sealing rubber airbag 61 is attached to the single-opening protective cover 3, the sealing rubber airbag 61 seals the inner sleeve 4 and the single-opening protective cover 3. At the same time, part of the sealing rubber airbag 61 is deformed due to the blocking of the curved surface portion 33 set on the inner wall of the single-opening protective cover 3. At this time, the deformed sealing rubber airbag 61 flips toward the alignment airbag 6, and cooperates with the limit of the inner wall of the single-opening protective cover 3 to squeeze and cover the alignment airbag 6. When the alignment airbag 6 is squeezed, the alignment airbag 6 expands, and the alignment airbag 6 on one side of the extrusion block 46 expands to push the extrusion block 46 to slide. At the same time, the extrusion block 46 slides to push the reset elastic plate 47 to deform and store force. At the same time, the extrusion block 46 drives the push plate 45 to move so that the push plate 45 pushes the two main elastic plates 44. At this time, the two main elastic plates 44 open to deform and store force and flip over and fit onto the horizontal platform 51 respectively. By using multiple main elastic plates 44 and push plates 45 to squeeze, limit and fix the horizontal platform 51, the substrate 5 is stably placed on the lining plate 41.

[0070] Furthermore, the sealing of the substrate 5 is further enhanced by utilizing the extrusion contact between the sealing rubber airbag 61 and the positioning airbag 6, and then the main spring 63 releases the stored force to push the locking rod 62. At this time, the first end of the locking rod 62 is inserted into the card slot 32 to lock the inner sleeve 4 on the single-opening shield 3. Therefore, the cooperation of the locking rod 62 and the main spring 63 can realize the rapid installation and fixation of the inner sleeve 4 and the substrate 5 thereon.

[0071] Furthermore, when it is necessary to disassemble and repair the base plate 5, after the worker grasps and fixes the gripping rod 43, he presses the U-shaped pressure rod 65 toward the gripping rod 43. At this time, the two ends of the U-shaped pressure rod 65 slide on the inclined groove surface 64 formed on the locking rod 62, so that the first end of the locking rod 62 is simultaneously disengaged from the locking groove 32. At this time, the inner sleeve 4 and the single-opening protective cover 3 are unlocked, so that the inner sleeve 4 can be quickly removed from the single-opening protective cover 3. When the sealing rubber airbag 61 moves away from the single-opening protective cover 3, the sealing rubber airbag 61 and the positioning airbag 6 recover their deformation, and the positioning airbag 6 releases the pressure on the squeezing block 46. Under the elastic reset of the reset elastic plate 47 and the main elastic plate 44, the main elastic plate 44 releases the limited fixation on the base plate 5. At the same time, the sealing rubber airbag 61 releases the blocking of the connecting ring 59, so that the base plate 5 can be quickly removed from the lining plate 41.

[0072] Therefore, by placing the substrate 5 on the lining plate 41 and pulling the inner sleeve 4 into the single-opening protective cover 3, the substrate 5 can be quickly limited and fixed, multi-layer sealed, and the inner sleeve 4 can be quickly locked on the single-opening protective cover 3, thereby facilitating the rapid disassembly and assembly of the substrate 5 for maintenance operations.

[0073] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
