Description

Technical Field

[0001] The invention relates to the technical field of ring network cabinets, in particular to an endoscopic observation window dedicated to a fully sealed ring network cabinet. Background Art

[0002] Ring Main Unit is a group of electrical equipment (high voltage switchgear) installed in a metal or non-metallic insulating cabinet or made into an assembled interval ring network power supply unit. Its core part adopts load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety.

[0003] At present, with the rapid development of my country's economy, the construction of power grids and urban network transformation is constantly deepening, and the number of electrical equipment has increased significantly. At the same time, the requirements for power supply reliability and safety are becoming higher and higher. Therefore, the demand for fully insulated and fully sealed metal enclosed ring network equipment is increasing rapidly. This product encloses the high-voltage live circuit in a metal gas box. The gas box is made of stainless steel and is welded and sealed by welding. The inside is filled with insulating gas to achieve modularization and miniaturization. As the demand for products increases and their use becomes more and more extensive, an observation window will be set on the outside of the existing ring network cabinet to view the situation inside the ring network cabinet. Through the setting of the observation window, when a fault occurs inside the ring network box, the internal status can be viewed and analyzed quickly for easy maintenance.

[0004] Although the setting of the observation window can facilitate maintenance, the dust-proof glass of the observation window is exposed to the outside for a long time. In this way, when the ring network cabinet is used in some windy and sandy areas, smaller wind and sand can be protected by silicone sleeves and goggles. When the wind is strong, the wind and sand will be brought into the inside of the goggles to wear the dust-proof glass, resulting in reduced clarity of the dust-proof glass. This will make it impossible to clearly observe the situation inside the ring network cabinet during use, affecting analysis and making it impossible to accurately perform maintenance. Therefore, there is an urgent need for a ring network cabinet observation window that can be used in a windy and sandy climate. Summary of the invention

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides a dedicated endoscopic observation window for a fully sealed ring main unit, which has the following beneficial effects:

[0017] 1. The fully sealed ring network cabinet is equipped with a special endoscopic observation window. When the outside wind becomes stronger and the distance between the two protective plates is reduced, the two protective plates are connected together by magnets, and the front side of the goggles is blocked by the two protective plates to prevent the sand brought by the strong wind from entering the inside of the goggles and wearing the dust-proof glass, resulting in reduced clarity of the dust-proof glass, thereby protecting the dust-proof glass inside the goggles.

[0018] 2. The fully sealed ring network cabinet is equipped with a special endoscopic observation window. Through the setting of a strong wind trigger device, the spring is squeezed when the windward plate moves. When the wind becomes smaller, the elastic force of the spring is used to push the windward plate open, and then the two protective plates are separated by the connecting rod. In this way, the device is protected in strong winds and the normal use of the device is not affected in light winds, thereby improving the convenience of the device.

[0019] 3. The fully sealed ring network cabinet is equipped with a special endoscopic observation window. Through the setting of a detachable cleaning device, the fixed frame drives the cleaning brush to rotate. The cleaning brush rotates to clean the stains on the dustproof glass, thereby preventing the stains from adhering to the dustproof glass and affecting the line of sight, thereby improving the practicality of the device.

[0020] 4. The fully sealed ring network cabinet has a special endoscopic observation window, which uses wind power to push the guide plate. No matter which direction the wind enters the functional box from, it can contact the guide plate. The wind power is used to push the guide plate. The device uses wind energy as a power source, making the device more environmentally friendly and energy-saving, while reducing the energy consumption of the device.

[0021] 5. The fully sealed ring network cabinet has a dedicated endoscopic observation window, which prevents dust from entering and affecting the observation effect through the setting of dustproof glass. The silicone sleeve on the goggles can prevent scratches when people are viewing, and effectively ensure the compression effect between the observation window and the ring network cabinet door panel to avoid metal gaps. Through the setting of this device, when a fault occurs inside the ring network box, the internal status can be checked and analyzed quickly for easy maintenance.

[0022] 6. The fully sealed ring network cabinet has a special endoscopic observation window. The lower ends of the two rotating rods are slidably connected to the two moving rods respectively. The two moving rods slide inside the two rotating rods respectively. By adjusting the positions of the two moving rods, the cleaning range can be changed, thereby improving the application range of the device.

[0023] 7. The fully sealed ring network cabinet has a special endoscopic observation window, and the upper and lower surfaces of the two sliders are fixedly connected with blocks. The four blocks are slidably connected to the four slots respectively. The setting of the blocks can prevent the protective plate from falling off during use, thereby reducing the failure rate of the device.

[0024] 8. The fully sealed ring network cabinet is equipped with a special endoscopic observation window, which uses the friction between the diamond sand and the sliding sleeve to counteract the wind force, so as to prevent the sliding sleeve from being pushed to move by a smaller wind force. In this way, a smaller wind force can be used to drive the detachable cleaning device to clean the dustproof glass.

[0025] 9. The dedicated endoscopic observation window of the fully sealed ring network cabinet can change the cleaning range by adjusting the position of the two moving rods, thereby improving the application range of the device. When using the device, when observation is needed, the detachable cleaning device can be quickly removed by removing the bolts. This not only does not affect the use of the observation window for observation, but also allows for simple and convenient installation and disassembly, saving time.

[0041] A support rod 7 is fixedly connected to the inside of the function box 2, and diamond sand 701 is arranged on the outer wall of the support rod 7, and the diamond sand 701 can increase the friction force of the outer wall of the support rod 7, and two sliding sleeves 702 are slidably connected to the support rod 7, and the lower surfaces of the two sliding sleeves 702 are rotatably connected to the rotating rod 9 with an internal hollow structure, and the lower ends of the two rotating rods 9 penetrate the goggles 101 and are rotatably connected to the goggles 101, and the lower ends of the two rotating rods 9 are respectively slidably connected to the two moving rods 4, and the two moving rods 4 slide inside the two rotating rods 9 respectively, and the outer walls of the two rotating rods 9 are fixedly connected with guide plates 10, and the guide plates 10 are located inside the function box 2, and the front surfaces of the two rotating rods 9 are threadedly connected with bolts 901, and the rear ends of the two bolts 901 penetrate the two rotating rods 9 and are respectively threadedly connected to the bolt holes 403 on the two moving rods 4;

[0042] When using the device, the two moving rods 4 are respectively placed inside the two rotating rods 9, and the positions of the two moving rods 4 are adjusted. After the position adjustment is completed, the bolts 901 are threadedly connected with the corresponding bolt holes 403 to fix them firmly. By adjusting the positions of the two moving rods 4, the cleaning range can be changed, thereby improving the application range of the device. When using the device, when observation is required, the bolts 901 can be removed to quickly remove the detachable cleaning device, which not only does not affect the use of the observation window for observation, but also allows for simple and convenient installation and disassembly, thereby saving time. When wind blows outside, the wind enters the functional box 2 through the ventilation slots 201. The wind enters the functional box 2 from any direction and contacts the guide plate 10, and the guide plate 10 is pushed by the wind. No matter which direction the wind enters the functional box 2, the guide plate 10 can contact the guide plate 10, and the guide plate 10 is pushed by the wind. The guide plate 10 uses the wind to drive the rotating rod 9 to rotate, and the rotating rod 9 drives the fixing frame 401 to rotate, and the fixing frame 401 drives the cleaning brush 402 to rotate. The cleaning brush 402 rotates to clean the stains on the dustproof glass 104, thereby preventing the stains from adhering to the dustproof glass 104 and affecting the line of sight, thereby improving the practicality of the device. The device uses wind energy as a power source, making the device more environmentally friendly and energy-saving, and reducing the energy consumption of the device at the same time;

[0043] A high wind trigger device is arranged inside the function box 2, and the high wind trigger device comprises two fixing rods 703, the two fixing rods 703 are respectively fixedly connected to the top surfaces of the two sliding sleeves 702, the top surfaces of the two fixing rods 703 are both fixedly connected with arc-shaped windward plates 704, the opposite surfaces of the two windward plates 704 are fixedly connected with springs 8, and the front surfaces of the two windward plates 704 are respectively fixedly connected with the two connecting rods 203;

[0044] When the device is used, when the external wind becomes stronger and the wind force entering the function box 2 is greater than the friction coefficient of the diamond sand 701, the windward plate 704 uses the wind force to drive the fixed rod 703 to move, and the fixed rod 703 drives the sliding sleeve 702 to slide on the support rod 7, and the windward plate 704 drives the connecting rod 203 to move, and the connecting rod 203 drives the protective plate 3 to move, and the movement of the protective plate 3 drives the slider 6 to slide inside the connecting groove 501, and the slider 6 drives the card block 601 to slide inside the card groove 502. When the distance between the two protective plates 3 is reduced, the two protective plates 3 are connected together by the magnet 301, and the front side of the eye shield 101 is blocked by the two protective plates 3 to prevent the wind and sand brought by the strong wind from entering the interior of the eye shield 101 and wearing the dustproof glass 104, resulting in reduced clarity of the dustproof glass 104, thereby protecting the dustproof glass 104 inside the eye shield 101.

[0045] By setting the diamond sand 701, when the device is used, when the wind force is small, the friction between the diamond sand 701 and the sliding sleeve 702 is used to resist the wind force, so as to prevent the small wind force from pushing the sliding sleeve 702 to move. In this way, the small wind force can be used to drive the detachable cleaning device to clean the dustproof glass 104;

[0046] The spring 8 is squeezed when the windward plate 704 moves. When the wind becomes smaller, the elastic force of the spring 8 is used to push the windward plate 704 away, and then the two protective plates 3 are separated by the connecting rod 203. In this way, the device is protected in strong winds and the normal use of the device is not affected in light winds, thereby improving the convenience of the device.

[0047] Working principle:

[0048] The first step is to fix the limit ring 103 to the observation point of the ring network cabinet. When in use, the eyes are close to the goggles 101 to observe the internal situation of the ring network cabinet through the entire device. The dustproof glass 104 is set to prevent dust from entering and affecting the observation effect. The silicone sleeve on the goggles 101 prevents scratches when people are checking, and effectively ensures the compression effect between the observation window and the door panel of the ring network cabinet to avoid metal gaps. Through the setting of this device, when a fault occurs inside the ring network box, the internal status can be checked and analyzed quickly for easy maintenance;

[0049] The second step is to put the two moving rods 4 into the two rotating rods 9 respectively, adjust the positions of the two moving rods 4, and after the position adjustment is completed, use the bolts 901 to thread the corresponding bolt holes 403 to fix them firmly. By adjusting the positions of the two moving rods 4, the cleaning range can be changed, thereby improving the application range of the device. When using the device, when observation is required, the bolts 901 can be removed to quickly remove the detachable cleaning device, which not only does not affect the observation using the observation window, but also allows simple and convenient installation and disassembly, thereby saving time;

[0050] In the third step, when the wind blows outside, the wind enters the interior of the function box 2 through the ventilation slot 201 and contacts the guide plate 10, and the guide plate 10 is pushed by the wind. No matter which direction the wind enters the interior of the function box 2, it can contact the guide plate 10, and the guide plate 10 is pushed by the wind. The guide plate 10 drives the rotating rod 9 to rotate by the wind, and the rotating rod 9 drives the fixing frame 401 to rotate, and the fixing frame 401 drives the cleaning brush 402 to rotate, and the cleaning brush 402 rotates to clean the stains on the dustproof glass 104;

[0051] Step 4: By setting the diamond sand 701, when the device is used, when the wind force is small, the friction between the diamond sand 701 and the sliding sleeve 702 is used to resist the wind force, so as to prevent the small wind force from pushing the sliding sleeve 702 to move, so that the small wind force can be used to drive the detachable cleaning device to clean the dustproof glass 104;

[0052] The fifth step is that when the external wind becomes stronger and the wind force entering the function box 2 is greater than the friction coefficient of the diamond sand 701, the windward plate 704 uses the wind force to drive the fixed rod 703 to move, and the fixed rod 703 drives the sliding sleeve 702 to slide on the support rod 7, and the windward plate 704 drives the connecting rod 203 to move, and the connecting rod 203 drives the protective plate 3 to move, and the movement of the protective plate 3 drives the slider 6 to slide inside the connecting groove 501, and the slider 6 drives the card block 601 to slide inside the card groove 502. When the distance between the two protective plates 3 is reduced, the two protective plates 3 are connected together by the magnet 301, and the front side of the eye shield 101 is blocked by the two protective plates 3 to prevent the wind and sand brought by the strong wind from entering the interior of the eye shield 101 and wearing the dustproof glass 104, resulting in a reduction in the clarity of the dustproof glass 104, thereby protecting the dustproof glass 104 inside the eye shield 101;

[0053] The sixth step is to squeeze the spring 8 when the windward plate 704 moves. When the wind becomes smaller, the elastic force of the spring 8 is used to push the windward plate 704 away, and then the two protective plates 3 are separated by the connecting rod 203. In this way, the device can be protected in strong winds and will not be affected in light winds. Normal use of the device is thus improved, thereby improving the convenience of the device.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
