[0002] In recent years, with the rapid development of my country's power industry and the improvement of technical equipment, SF6 electrical equipment has been widely used in power systems. There are many SF6 electrical equipment and they often leak after long-term operation, which requires regular replenishment of SF6 gas to maintain sufficient gas volume. SF6 gas replenishment usually uses SF6 filling equipment to transport SF6 gas cylinders to gas transmission points for gas transmission. When the gas cylinders stored in the SF6 filling equipment are used up, they need to be replaced with new gas cylinders.

[0003] The existing method of replacing gas cylinders is to use a manually operated robotic arm, manually install the hook, and then lift the gas cylinder.

The first electromagnet and the second electromagnet are respectively arranged inside the first electromagnetic part and the second electromagnetic part, which can generate magnetic force for lifting by connecting to the power supply circuit, greatly reducing the safety risk caused by the hook falling off or breaking, and has higher safety. The shape design of the special lifting magnetic suction working surface can ensure that the lifting magnetic suction working surface fits the surface of the object to be lifted during the lifting process, thereby improving the stability of the lifting. After the safety chain is matched with the safety hanging point located at the object to be lifted, it is buckled and connected to the buckle connection part, which not only increases the safety, but also provides double protection. The operator can Before installation, the safety chain must be passed through the safety hanging point, and only after it is installed in place and triggers the second switch component, the first electromagnet and the second electromagnet can be energized normally. During the lifting process, the safety chain can also prevent the first electromagnet and the second electromagnet from falling due to accidental failure, further improving safety. A trigger component is provided at the first lifting matching surface and a first switch component for being triggered by the trigger component is provided at the second lifting matching surface. The trigger component and the first switch component cooperate to further provide a layer of safety protection. Only after the operator installs the first electromagnetic component body and the second electromagnetic component body in place before lifting, the first electromagnet and the second electromagnet can be energized normally, further improving safety.

[0006] Preferably, the first hoisting mating surface includes a first mating surface and a second mating surface respectively formed at two ends of the one side of the first electromagnetic component body, and the second hoisting mating surface includes a third mating surface and a fourth mating surface respectively formed at two ends of the one side of the second electromagnetic component body; the first mating surface is used to form a mating with the third mating surface, and the second mating surface is used to form a mating with the fourth mating surface; A first docking structure is provided at at least one of the first mating surface and the second mating surface, and a second docking structure is correspondingly provided at at least one of the third mating surface and the fourth mating surface; the first docking structure and the second docking structure together form a safety docking component; The trigger member is formed at the first docking structure, and the first switch member is formed at the second docking structure.

[0009] Through the present invention, the lifting point is usually higher. For safety reasons, traditional hook lifting requires the participation of multiple people to install the hook to the predetermined lifting position during the lifting preparation stage. In the present invention, the structural design of the first docking structure and the second docking structure greatly reduces the work in the preparation stage. Only one person can easily complete the pre-lifting preparation, insert the guide rod into the guide hole, complete the docking of the first docking structure and the second docking structure, so that the first electromagnetic component and the second electromagnetic component reach a predetermined lifting state; the guide rod and the guide hole are clearance-matched, and this design can accommodate a slight misalignment between the first electromagnetic component and the second electromagnetic component to avoid damage caused by excessive stress during use. At the same time, since the clearance fit does not require a tight tolerance, the guide rod can be more easily installed in the guide hole, which is also more convenient when maintenance or replacement is required. When there is a gap between the guide rod and the guide hole, it is not easy to get stuck even in the presence of contaminants.

[0010] Preferably, the first switch element includes two metal electrodes arranged inside the guide hole, and the two metal electrodes are connected in series to the power supply circuit; the trigger element includes a metal conductive block formed at the end of the guide rod, and the metal conductive block is used to cooperate with the two metal electrodes.

[0011] Through the present invention, when the guide rod is inserted into the guide hole, the metal conductive block automatically cooperates with the metal electrode to trigger the first switch, thereby simplifying the operation process and making the operation simpler; the cooperation design of the metal electrode and the conductive block is that the circuit connection can be completed only after full alignment and insertion, which increases the safety of operation and reduces circuit errors or equipment failures caused by misoperation; the metal electrode is designed inside the guide hole, so that the overall structure is more compact and space is saved, and the structure of the metal electrode and the metal conductive block is relatively simple, easy to inspect and maintain, and easy to discover and solve problems.

[0013] Through the present invention, the electrical installation cavity formed inside the second electromagnetic component provides a centralized space for installing and fixing electrical components, making the overall structure more concise; the plastic sleeve is used to carry the metal electrode, the outer wall of the plastic sleeve is threadedly connected to the inner wall of the guide hole and is provided with a metal electrode installation groove, this design provides protection for the metal electrode and ensures that the metal electrode will not shift during use; the design of the insertion cavity bottom plate ensures that the guide rod inserted into the cavity will not continue to go deeper after reaching a certain depth, playing a limiting role; the metal electrode is inserted into the electrical installation cavity through the first electrode socket and the second electrode socket at the same time, this design can provide a fixation between the plastic sleeve and the guide hole to prevent the plastic sleeve and the guide hole from rotating during use.

[0015] Through the present invention, the design of the contact part arching toward the inner cavity of the plastic sleeve can ensure better contact pressure with the metal conductive block, thereby improving the reliability of contact conduction. At the same time, the arched contact part helps to stabilize the position of the metal conductive block and prevent accidental power failure due to vibration or other external forces. Due to the existence of the contact part, the metal conductive block can be prevented from directly hitting the inner wall of the plastic sleeve to a certain extent, thereby protecting the inner wall from damage. If the contact part is worn or damaged, it can be easily replaced because it is designed as an independent component. The contact part formed by stamping has good wear resistance, can maintain a good contact state during long-term use, and the stamping process of the contact part is relatively simple, easy to mass produce, and can reduce manufacturing costs.

[0016] Preferably, one side of the base portion used to cooperate with the metal electrode mounting groove is bent at both ends in the width direction to form an inserting portion, and the inserting portion and the base portion together form a C-shaped inserting area, and a T-shaped track for cooperating with the C-shaped inserting area is formed at the bottom wall of the metal electrode mounting groove.

[0017] Through the present invention, the design of the T-shaped track makes the metal electrode more firmly fixed, will not shift during installation and use, and helps to accurately guide the plug-in part, improve the installation accuracy, and ensure the correct installation of the metal electrode; the plug-in part formed by the bend increases the mechanical strength of the structure and improves the mechanical strength of the electrode; the shape design of the plug-in area and the T-shaped track simplifies the installation process, making the installation process of the metal electrode simpler and reducing the installation time and difficulty.

[0019] Through the present invention, the two first switch components are connected in parallel to improve the reliability of the circuit. When one switch component has a problem, the other one can still work, ensuring the continuity of the circuit and improving the safety of the lifting. After the two first switch components are connected in parallel, they are connected in series with the second switch component and the main switch component to the power supply circuit. This design provides triple safety protection. The circuit will be connected only when the first switch component, the second switch component and the main switch component are all turned on, which greatly increases the safety of the lifting assembly.

[0035] Through this embodiment, when the guide rod 710 is inserted into the guide hole 720, the metal conductive block 820 automatically cooperates with the metal electrode 810 to trigger the first switch 320, thereby simplifying the operation process and making the operation simpler; the cooperation between the metal electrode and the conductive block is designed to complete the circuit connection only after full alignment and insertion, which increases the safety of operation and reduces circuit errors or equipment failures caused by misoperation; the metal electrode 810 is designed inside the guide hole 720, so that the overall structure is more compact and saves space, and the structure of the metal electrode 810 and the metal conductive block 820 is relatively simple, easy to inspect and maintain, and easy to discover and solve problems.

Due to the existence of the contact portion 814, the metal conductive block 820 can be prevented from directly hitting the inner wall of the plastic sleeve 860 to a certain extent, thereby protecting the inner wall from damage. If the contact portion 814 is worn or damaged, it can be easily replaced because it is designed as an independent component.

A T-shaped track 817 for cooperating with the C-shaped plug-in area 816 is formed at the bottom wall of the metal electrode mounting groove 812.

[0041] Through this embodiment, the design of the T-shaped track 817 makes the metal electrode 810 more firmly fixed, does not shift during installation and use, and helps to accurately guide the plug-in portion 815, thereby improving the installation accuracy and ensuring the correct installation of the metal electrode 810; the bent plug-in portion 815 increases the mechanical strength of the structure and improves the mechanical strength of the electrode; the shape design of the plug-in area 816 and the T-shaped track 817 simplifies the installation process, making the installation process of the metal electrode 810 simpler and reducing the installation time and difficulty.

[0046] Example 3 This embodiment provides a heating device 1015 that can be used in Embodiment 1, such as Figure 16-25 As shown, it includes a gas cylinder heating device 2020, which includes a heating device body 1110. A placement cavity 1112 for placing a gas cylinder is formed inside the heating device body 1110. The placement cavity 1012 opens upward, and an air curtain 1113 is provided at the top opening of the placement cavity 1012. A placement plate 1114 parallel to the bottom wall of the placement cavity 1012 is provided in the placement cavity 1012. A semi-enclosed heating area 1210 is formed between the air curtain 1113 and the placement plate 1112. A heating component 1211 for heating the gas cylinder 1013 is provided in the heating area 1210.

[0047] According to the present embodiment, an air curtain 1113 is provided at the top opening of the placement cavity 1012, and the air curtain 1113 forms a protective layer during the heating process to reduce the diffusion of heat and reduce energy loss; the heating component 1211 is arranged in a semi-enclosed heating area 1210 to further reduce heat loss and improve the heating efficiency of the gas cylinder 1013; the heating component 1211 is different from the traditional heating plate and steam heating component, and its heating method is improved to a combination of water bath heating and steam heating, and its heating effect is better.

[0048] In this embodiment, two rows of positioning holes 1115 are evenly formed along the length direction of the placement plate 1114, and the two rows of positioning holes 1115 are placed in sequence to form two gas cylinders 1013. The inner walls of the positioning holes 1115 are in close contact with the outer walls of the gas cylinders 1013, and a vertically arranged first partition plate 1116 is provided at the symmetry plane between the two gas cylinders 1013. The first partition plate 1116 is vertically arranged above the placement plate 1114, and a plurality of vertically arranged second partition plates 1117 are provided at the symmetry plane between the gas cylinders 1013. The second partition plate 1117 is perpendicular to the first partition plate 1116 and the placement plate 1114 and is arranged above the placement plate 1114. The first partition plate 1116 and the second partition plate 1117 divide the placement cavity 1012 into a plurality of completely symmetrical heating blocks 1118. The heating blocks 1118 constitute a heating area 1210, and the heating blocks 1118 are each provided with a heating assembly 1211.

[0049] Through this embodiment, two rows of positioning holes 1115 are evenly formed along the length direction of the placement plate 1114, which improves the stability of the gas cylinder 1013 during the heating process and prevents the gas cylinder 1013 from rolling or shifting; since not every heating block 1118 needs to be heated, the gas cylinder 1013 loaded with SF6 needs to be heated during the inflation process, while the gas cylinder 1013 loaded with nitrogen does not need to be heated, and the design of the first partition plate 1116 and the second partition plate 1117 helps to separate the various heating blocks 1118 and reduce the mutual interference between the heating blocks 1118, thereby improving the stability of the system; the design of multiple heating blocks 1118 allows different heating strategies to be used in different inflation occasions, which is specifically manifested in that the gas ratio of SF6 and nitrogen can be adjusted as needed, and then whether the heating block 1118 is heated is adjusted according to the gas ratio of SF6 and nitrogen, which has higher flexibility; the first partition plate 1116 and the second partition plate 1117 are both made of insulating materials.

[0050] In this embodiment, a sealed steam chamber 1310 is formed between the placement plate 1114 and the bottom wall of the placement chamber 1012 , and water and a heat source 1320 for heating the water to generate steam are placed in the steam chamber 1310 .

[0051] Through this embodiment, the closed steam chamber 1310 can effectively reduce the loss of heat to the external environment, thereby improving the thermal efficiency of the entire device; the steam pressure in the closed space can be increased, which helps to improve the water heating speed and steam generation efficiency.

[0052] In this embodiment, condensed water is stored in the heating block 1118, and the area between below the condensed water liquid level 1330 and the placement plate 1114 is the water bath heating zone 1340, and the water bath heating zone 1340 is used to perform water bath heating on the middle and lower part of the gas cylinder 1013; the area between above the condensed water liquid level 1330 and the air curtain 1113 is the steam heating zone 1350, and the steam heating zone 1350 is used to perform steam heating on the middle and upper part of the gas cylinder 1013; the water bath heating zone 1340 and the steam heating zone 1350 together constitute the heating block 1118.

[0053] Through this embodiment, the heating block 1118 is divided into a water bath heating zone 1340 and a steam heating zone 1350, so that the entire gas cylinder 1013 can be heated, making the heating more uniform, which helps to improve the heating efficiency; the water bath heating zone 1340 has a large specific heat capacity of water and the temperature changes slowly, so there will be no sudden temperature rise to cause danger, and the steam heating zone 1350 can ensure the safety of the device by controlling the pressure and flow of steam, thereby increasing the safety of the device: uniform heating helps to improve the heating effect and reduce the deformation of the gas cylinder 1013 caused by uneven heating during the heating process.

[0054] In this embodiment, the heating component 1211 includes a plurality of steam nozzles 1410 arranged above the placement plate 1114, the steam nozzles 1410 are used to spray steam, and the steam nozzles 1410 include a nozzle body 1411, and an air inlet 1412 and an air outlet 1413 are respectively provided at both ends of the nozzle body 1411, and the gas discharge direction of the air outlet 1413 points to the upper half of the gas cylinder 1013, and the air outlet 1413 is located in the steam heating zone 1350; the heating component 1211 also includes a plurality of one-way valve reflux devices 1420 for returning condensed water to the steam chamber 1310, the one-way valve reflux devices 1420 are embedded in the placement plate 1114 and unidirectionally connect the heating block 1118 and the steam chamber 1310; each heating block 1118 includes a one-way valve reflux device 1420 and at least one steam nozzle 1410.

[0055] Through this embodiment, steam is generated in the steam chamber 1310, and the steam enters from the air inlet 1412 of the steam nozzle 1410, passes through the nozzle body 1411, and is ejected from the air outlet 1413. The gas discharge direction points to the upper part of the gas cylinder 1013, and the steam fills the steam heating area 1350 to heat the upper part of the gas cylinder 1013. The steam is liquefied when it is cooled, and condensed water flows to the bottom of the gas cylinder 1013 to form a water bath heating area 1340. The condensed water itself has a certain temperature, and the temperature is higher than the temperature of the gas cylinder 1013. The condensed water gathers and submerges the bottom of the gas cylinder 1013 and heats the bottom of the gas cylinder 1013 in a water bath. Water is a heat conduction medium with large specific heat capacity and high conduction efficiency. Its direct contact with the gas cylinder 1013 greatly improves the heat transfer efficiency. The one-way valve reflux device 1420 is provided with a connected pressure threshold. As the steam continues to be ejected, the condensed water gathers, and the heating The condensed water level 1330 in the hot block 1118 increases, and the pressure on the side of the one-way valve reflux device 1420 close to the heating block 1118 increases. When the pressure is greater than the threshold of the one-way valve reflux device 1420, the condensed water in the heating block 1118 begins to reflux, and the liquid level remains constant. The steam chamber 1310 reheats the reflux water into steam, forming a stable cycle, thereby ensuring that the temperature and liquid level of the condensed water in the heating block 1118 are also relatively stable, that is, ensuring the stability of the water bath heating. At the same time, the circulation of the liquid also ensures that the steam can be continuously ejected. The combination of the two heating methods can better heat the gas cylinder 1013; each heating block 1118 includes a one-way valve reflux device 1420 and at least one steam nozzle 1410, and multiple steam nozzles 1410 can be provided to achieve rapid steam ejection, thereby further improving the heating efficiency.

[0056] In this embodiment, the one-way valve reflux device 1420 includes a one-way valve body 1421 , and a switch 1422 for fully opening the channel of the one-way valve body 1421 is provided on the side of the one-way valve body 1421 .

[0057] Through this embodiment, after the device is used, condensed water accumulates in the heating block 1118. At this time, opening the switch 1422 can fully open the channel of the one-way valve body 1421 to completely discharge the condensed water. In an emergency, if the steam chamber 1310 fails and the internal pressure is too high, the one-way valve body 1421 can be fully opened quickly through the switch 1422 to release the internal pressure of the steam chamber 1310, thereby protecting the safety of the device and improving the overall safety of the device.

[0058] In this embodiment, a steel ring 1510 for fixing the gas cylinder 1013 is provided on the air curtain 1113 .

[0059] Through this embodiment, the steel ring 1510 provides fixation for the gas cylinder 1013, prevents the gas cylinder 1013 from shifting due to various factors during the heating process, and ensures the stability of the gas cylinder 1013 during the heating process.

[0060] In this embodiment, the steam spray head 1410 further includes an adjustment switch 1414 disposed on the side of the spray head body 1411 , and the adjustment switch 1414 is used to adjust the steam volume and the opening and closing of the steam spray head 1410 .

[0061] Through this embodiment, the regulating switch 1414 allows the operator to accurately control the flow rate of steam as needed, thereby achieving temperature control. The operator can quickly adjust the size of the steam to improve the flexibility of operation; the regulating switch 1414 also controls whether the corresponding heating block 1118 is heated. When the regulating switch 1414 is turned on, the heating block 1118 is heated, and when the regulating switch 1414 is turned off, the heating block 1118 is not heated, that is, the heating block 1118 where the gas cylinder 1013 loaded with SF6 is placed turns on the regulating switch 1414 for heating, and the heating block 1118 where the gas cylinder 1013 loaded with nitrogen is placed turns off the regulating switch 1414 for no heating.

[0062] In this embodiment, a pressure limiting valve 1610 is provided on the side of the steam chamber 1310 to prevent excessive pressure inside the steam chamber 1310, and a protective cover 1620 is provided on the outer side of the pressure limiting valve 1610 to prevent steam from spraying out and injuring people.

[0063] Through this embodiment, the pressure limiting valve 1610 can prevent the internal pressure of the steam chamber 1310 from exceeding the safety threshold, thereby avoiding equipment damage or explosion risks caused by excessive pressure. The protective cover 1620 protects the operator from direct harm from high-temperature steam, reducing the potential risk of injury to the operator.
