Description

Technical Field

[0001] The utility model relates to the technical field of plasma generators, and more specifically to a generator auxiliary connecting device and a plasma generator system. Background Art

[0002] The working principle of a plasma generator is to generate a high-temperature thermal plasma jet by high-voltage ionized air. To maintain its normal and stable operation, it must have high voltage electricity, a working medium (usually air is preferred) and cooling water. The connection method between water, electricity and gas and the plasma generator can indirectly affect the complexity of the plasma generator structure and the convenience of fault inspection and maintenance.

[0003] At present, plasma generators have relatively mature water-electricity integrated cabinet applications. This water-electricity integrated cabinet has played a certain role in simplifying the structure of the plasma generator and improving the convenience of on-site maintenance. However, water and electricity are arranged vertically in the integrated cabinet with the water interface on the top and the electricity interface on the bottom. Once the water interface leaks, the positive and negative electrical interfaces below the water interface will short-circuit and cause a fault, which poses a great safety hazard.

[0050] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not impose any limitation on the content of the utility model described in the claims. Further, all the contents of the configurations shown in the following embodiments are not necessarily essential for the solution of the utility model described in the claims. It should be noted that for the sake of convenience of description, only the parts related to the relevant utility model are shown in the drawings. Without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0051] An embodiment of the utility model discloses an auxiliary connection device for a generator, which is used to connect a plasma generator and a power cabinet, ensure safety between water and electricity, eliminate potential safety hazards, and ensure the safe and reliable operation of the plasma generator.

[0052] As Figure 1 and Figure 3 shown, the auxiliary connection device for a generator disclosed in the embodiment of the utility model includes a support device and two spaced water-electricity spindle assemblies supported on the support device. The two water-electricity spindle assemblies are respectively used to connect a water-cooled cable and another water-cooled cable of the plasma generator.

[0053] In this embodiment, the structures of the two water-electricity spindle assemblies are the same, and each includes a conductive half-shaft, an insulating half-shaft, and a cable socket. For the convenience of understanding, the two water-electricity spindle assemblies are respectively defined as a first water-electricity spindle assembly 300 and a second water-electricity spindle assembly 400.

[0054] The first water-electricity spindle assembly 300 includes a first conductive half-shaft 302, a first insulating half-shaft 301, and a first cable socket 308. Among them, the first conductive half-shaft 302 has an axially penetrating conductive shaft water passage hole for cooling water to pass through. The first conductive half-shaft 302 is made of a conductive material, for example, a metal material can be used. Since the first conductive half-shaft 302 needs to pass cooling water, in order to achieve the anti-corrosion effect, the material of the first conductive half-shaft 302 can be selected as stainless steel with better anti-corrosion effect.

[0055] The first insulating half-shaft 301 has an axially penetrating insulating shaft water passage hole for cooling water to pass through. The first insulating half-shaft 301 is made of an insulating material, for example, the first insulating half-shaft 301 is made of bakelite. The first end of the first conductive half-shaft 302 and the first end of the first insulating half-shaft 301 are hermetically butt-jointed axially to obtain a first water-electricity spindle.

[0056] After the first conductive half-shaft 302 and the first insulating half-shaft 301 are hermetically butt-jointed axially, the conductive shaft water passage hole and the insulating shaft water passage hole are in a communicating state, and the hermetic butt-joint of the first conductive half-shaft 302 and the first insulating half-shaft 301 can prevent water from leaking at the connection of the conductive shaft water passage hole and the insulating shaft water passage hole.

[0057] The second end of the first conductive half shaft 302 has a first cable joint for connecting the first water-cooled cable 306 of the plasma generator, and the second end of the first insulating half shaft 301 has a first water pipe joint for connecting the first cooling water pipe 305. The second end of the first conductive half shaft 302 and the second end of the first insulating half shaft 301 can be understood as the two ends of the first water and electricity core shaft, that is, one end of the first water and electricity core shaft is the first cable joint for connecting the first water-cooled cable 306 of the plasma generator, and the other end of the first water and electricity core shaft is the first water pipe joint for connecting the first cooling water pipe.

[0058] One end of the first water-cooled cable 306 is connected to the first cable joint of the first water and electricity core shaft, and the other end is connected to the cathode of the plasma generator. The first water-cooled cable 306 can be connected to the first cable joint of the first water and electricity core shaft by means of ball head conical surface sealing and thread locking. One end of the first cooling water pipe 305 can be connected to the first water pipe joint through the first lock nut type joint 304, and the other end of the first cooling water pipe 305 is connected to the water supply device.

[0059] The first cable socket 308 is electrically connected to the first conductive half shaft 302 through the first electrical connection component. The first cable socket 308 is used to connect to the cathode cable of the power cabinet. The vertical height of the first cable socket 308 is not lower than the vertical height of the first insulating half shaft 301 to prevent the water leakage at the docking part of the first cooling water pipe 305 and the first water pipe joint from causing a short circuit between the first cable socket 308 and the second cable socket 408 of the second water and electricity core shaft assembly 400.

[0060] Similarly, the second water and electricity core shaft assembly 400 includes a second conductive half shaft 402, a second insulating half shaft 401, and a second cable socket 408. Among them, the second conductive half shaft 402 has a conductive shaft water through hole penetrating axially, and the conductive shaft water through hole is used for the cooling water to pass through. The second conductive half shaft 402 is made of a conductive material, for example, a metal material can be used. Since the second conductive half shaft 402 needs to pass cooling water, in order to achieve the anti-corrosion effect, the material of the second conductive half shaft 402 can be selected as stainless steel with better anti-corrosion effect.

[0061] The second insulating half shaft 401 has an insulating shaft water through hole penetrating axially, and the insulating shaft water through hole is used for the cooling water to pass through. The second insulating half shaft 401 is made of an insulating material, for example, bakelite is used. The first end of the second conductive half shaft 402 and the first end of the second insulating half shaft 401 are hermetically butted axially to obtain the second water and electricity core shaft.

[0062] After the second conductive half shaft 402 and the second insulating half shaft 401 are hermetically butted axially, the conductive shaft water through hole and the insulating shaft water through hole are in a communicating state, and the hermetic butt joint of the second conductive half shaft 402 and the second insulating half shaft 401 can prevent water from leaking at the connection of the conductive shaft water through hole and the insulating shaft water through hole.

[0063] The second end of the second conductive half shaft 402 has a second cable joint for connecting the second water-cooled cable 406 of the plasma generator, and the second end of the second insulating half shaft 401 has a second water pipe joint for connecting the second cooling water pipe 405. The second ends of the second conductive half shaft 402 and the second insulating half shaft 401 can be understood as the two ends of the second water and electricity core shaft, that is, one end of the second water and electricity core shaft is the second cable joint for connecting the second water-cooled cable 406 of the plasma generator, and the other end of the second water and electricity core shaft is the second water pipe joint for connecting the second cooling water pipe 405.

[0064] One end of the second water-cooled cable 406 is connected to the second cable joint of the second water and electricity core shaft, and the other end is connected to the anode of the plasma generator. The second water-cooled cable 406 can be connected to the second cable joint of the second water and electricity core shaft by means of ball head conical surface sealing plus thread locking. One end of the second cooling water pipe 405 can be connected to the second water pipe joint through the second lock nut type joint 404, and the other end of the second cooling water pipe 405 is connected to the return water or water supply device.

[0065] The second cable socket 408 is electrically connected to the second conductive half shaft 402 through the second electrical connection component. The second cable socket 408 is used to connect to the anode cable of the power cabinet. The vertical height of the second cable socket 408 is not lower than the vertical height of the second insulating half shaft 401 to prevent the water leakage at the docking part of the second cooling water pipe 405 and the second water pipe joint from causing a short circuit between the first cable socket 308 and the second cable socket 408.

[0066] The generator auxiliary connection device provided by the present utility model can quickly realize the connection of the water supply system and the power cabinet to the plasma generator. Specifically, the anode cable led from the power cabinet can be inserted into one of the cable sockets, and the cathode cable led from the power cabinet can be inserted into the other cable socket. For example, the anode cable 409 led from the power cabinet can be inserted into the second cable socket 408, and the cathode cable 309 led from the power cabinet can be inserted into the first cable socket 308.

[0067] The cooling water pipe led from the water supply or return water system is connected to the water pipe joints of the two insulating half shafts. For example, the first cooling water pipe 305 led from the water supply system is connected to the first water pipe joint of the first insulating half shaft 301, and the second cooling water pipe 405 led from the return water or water supply system is connected to the second insulating half shaft 401 of the second insulating half shaft 401.

[0068] The two water-cooled cables of the plasma generator are respectively connected to the cable joints of the two conductive half shafts. For example, the first water-cooled cable 306 of the plasma generator is connected to the first cable joint of the first conductive half shaft 302; the second water-cooled cable 406 of the plasma generator is connected to the second cable joint of the second conductive half shaft 402.

[0069] The vertical height of the cable socket is not lower than the vertical height of the insulating half shaft, that is, the power connection position is higher than the water connection position, or is at the same height as the water connection position, so that even if there is water leakage at the water connection position, it will not cause a short circuit between the two cable sockets. The generator auxiliary connection device provided by the utility model can firstly realize rapid disassembly and assembly, convenient installation and maintenance, and significant modular effect. Secondly, it eliminates the safety hazards between water and electricity, fully guarantees the safe and stable operation of the plasma generator, and finally helps to simplify the structure of the plasma generator.

[0070] In a specific embodiment of the present invention, the first electrical connection assembly includes a first conductive locking ring 311 and a first conductive copper bar 307. The first conductive locking ring 311 is tightly attached to the first conductive semi-shaft 302, and the first conductive locking ring 311 has a first conductive connection portion.

[0071] One end of the first conductive copper bar 307 is connected to the first conductive connection part, and the other end is connected to the corresponding first cable socket 308. The first conductive copper bar 307 can be designed as a right-angle copper bar with an L-shaped structure to facilitate the connection with the first conductive connection part and the first cable socket 308. The first conductive semi-shaft 302 is electrically connected to the first cable socket 308 through the first conductive locking ring 311 and the first conductive copper bar 307.

[0072] Further, the first conductive locking ring 311 can be slidably sleeved on the first conductive semi-shaft 302 and locked by the fastener 313. Before the fastener 313 is locked, the first conductive locking ring 311 can slide along the first conductive semi-shaft 302. Before the first hydropower spindle is installed on the supporting device, the first conductive locking ring 311 needs to be sleeved on the first hydropower spindle. Then the first conductive copper bar 307 is connected to the first cable socket 308, and then the first conductive locking ring 311 is slid so that the first conductive connection part is docked with the first conductive copper bar 307, and then fixed. In this embodiment, by slidably sleeved on the first conductive semi-shaft 302, the position of the first conductive locking ring 311 can be adjusted according to the size of the first conductive copper bar 307 and the position after installation, so that the connection can be completed.

[0073] The first conductive locking ring 311 can be made of copper material, and has a locking circular hole that matches the outer diameter of the first hydropower spindle. The first conductive locking ring 311 has a locking slit of a certain width (such as 2-4 mm) opened along the axial direction, and a bolt fastening hole perpendicular to the locking circular hole is provided at the locking slit. The fastener 313 passes through the bolt fastening hole and is locked, so that the first conductive locking ring 311 is tightly held on the first conductive semi-shaft 302.

[0074] One end of the first conductive copper bar 307 can be connected to the first conductive connection part through the fastener 312, and the other end can be connected to the first cable socket 308 through the fastener 310. The first conductive copper bar 307 can be made of red copper material, and long circular hole-shaped fastening holes capable of adjusting positions are provided at both ends, so that the fastening positions can be adjusted according to requirements, avoiding fastening failures caused by the fasteners 312 and 310 being unable to be inserted into the fastening holes due to errors.

[0075] Correspondingly, the second electrical connection component includes a second conductive locking ring 411 and a second conductive copper bar 407. Among them, for the structural characteristics of the second conductive locking ring 411 and the second conductive copper bar 407, the fixing relationship between the two, the relationship between the second conductive locking ring 411 and the second water and electricity mandrel, and the relationship between the second conductive copper bar 407 and the second cable socket 408, reference can be made to the first electrical connection component disclosed in the above embodiment. Since the second electrical connection component has the same structure and connection relationship as the first electrical connection component, it will not be elaborated here.

[0076] In a specific implementation of the present utility model, an external thread connection part is provided at the first end of one of the first conductive half shaft 302 and the first insulating half shaft 301, and an internal thread connection part is provided at the first end of the other. The external thread connection part is in threaded cooperation with the internal thread connection part, and a seal 303 is provided on the butting end face of the first end of the first conductive half shaft 302 and the first end of the first insulating half shaft 301. The first conductive half shaft 302 and the first insulating half shaft 301 can have the same outer diameter to ensure that the first water and electricity mandrel has a consistent outer diameter.

[0077] In order to improve the installation stability of the seal 303, further, the first end of the first conductive half shaft 302 is a stepped shaft structure, and the outermost end is an external thread connection part. Figure 1 In the shown solution, the first end of the first conductive half shaft 302 has two shaft segments, and the shaft segment located at the end is an external thread connection part.

[0078] The first end of the first insulating half shaft 301 is a stepped hole structure that is in concave-convex fit with the stepped shaft structure of the first conductive half shaft 302. The stepped hole structure has at least a positioning hole communicating with the insulating shaft water passing hole. The internal thread connection part is arranged in the insulating shaft water passing hole, and the seal 303 is arranged on the stepped surface where the positioning hole is connected to the insulating shaft water passing hole. With such a setting, the end faces and the outer ring at both axial ends of the seal 303 are limited, so that the seal 303 is reliably installed in the sealing position.

[0079] Correspondingly, the connection and sealing structure of the second conductive half shaft 402 and the second insulating half shaft 401 can refer to the connection and sealing structure of the first conductive half shaft 302 and the first insulating half shaft 301 disclosed in the above embodiment. Since the second conductive half shaft 402 and the second insulating half shaft 401 have the same connection and sealing structure as the first conductive half shaft 302 and the first insulating half shaft 301, it will not be elaborated herein.

[0080] In a specific embodiment of the present utility model, the generator auxiliary connection device may further include a gas core shaft assembly 500 supported on the support device. The gas core shaft assembly 500 includes a gas core shaft 501, which has an axially penetrating ventilation hole. One end of the gas core shaft 501 has an air inlet joint for connecting an inlet pipe 505, and the other end has an air outlet joint for connecting an outlet pipe 504. The gas core shaft assembly 500 can be provided with one according to requirements, or multiple can be provided.

[0081] The inlet pipe 505 is used to connect to the gas supply system, and the outlet pipe 504 is used to connect to the air inlet joint of the plasma generator. The present utility model integrates three paths of water, electricity, and gas, and can realize quick disassembly and assembly by using their respective interfaces, which is convenient for installation and maintenance, highlighting the modular effect.

[0082] Before the plasma generator operates, the anode cable 409 led from the power cabinet is inserted into the second cable socket 408, and the cathode cable 309 led from the power cabinet is inserted into the first cable socket 308; the first cooling water pipe 305 led from the water supply system is connected to the first water pipe joint of the first insulating half shaft 301, and the second cooling water pipe 405 led from the return water or water supply system is connected to the second water pipe joint of the second insulating half shaft 401.

[0083] The first water-cooled cable 306 of the plasma generator is plugged into the first cable joint of the first conductive half shaft 302; the second water-cooled cable 406 of the plasma generator is plugged into the second cable joint of the second conductive half shaft 402.

[0084] The inlet pipe 505 led from the gas supply system is connected to the air inlet joint of the gas core shaft 501 through a pneumatic joint 502, one end of the outlet pipe 504 is connected to the air outlet joint of the gas core shaft 501 through a pneumatic joint 503, and the other end of the outlet pipe 504 is connected to the air inlet joint of the plasma generator.

[0085] When the plasma generator operates, the high-voltage direct current positive path: power cabinet → anode cable 409 → second cable socket 408 → second conductive copper bar 407 → second conductive locking ring 411 → second conductive half shaft 402 → second water-cooled cable 406 → generator anode;

[0086] High-voltage direct current negative electrode path: power supply cabinet → cathode cable 309 → first cable socket 308 → first conductive copper bar 307 → first conductive locking ring 311 → first conductive half shaft 302 → first water-cooled cable 306 → generator cathode;

[0087] As Figure 1 shown, the cooling water path: water supply system → first cooling water pipe 305 → first lock nut type joint 304 → first water and electricity core shaft connected to the negative electrode of direct current (first insulating half shaft 301 + first conductive half shaft 302) → first water-cooled cable 306 → generator cathode → generator anode → second water-cooled cable 406 → second water and electricity core shaft connected to the positive electrode of direct current (second conductive half shaft 402 + second insulating half shaft 401) → second lock nut type joint 404 → second cooling water pipe 405 → return water system. At this time, the cathode and anode are connected in series;

[0088] Gas (working medium) path: gas supply system → inlet pipe 505 → pneumatic joint 502 → gas core shaft 501 → pneumatic joint 503 → outlet pipe 504 → plasma generator. At this time, it is the case where there is only one-stage gas for the working medium. If there are multiple stages of gas, multiple gas core shaft assemblies 500 can be added in parallel in the same way.

[0089] As Figure 3 shown, in the solution disclosed in another embodiment of the present utility model, the cooling water path can also adopt a structure form with the cathode and anode in parallel.

[0090] Specifically, the parallel cooling water path is as follows:

[0091] One-way water supply system → first cooling water pipe 305 → first lock nut type joint 304 → first water and electricity core shaft connected to the negative electrode of direct current (first insulating half shaft 301 + first conductive half shaft 302) → first water-cooled cable 306 → generator cathode;

[0092] Another way water supply system → second cooling water pipe 405 → second lock nut type joint 404 → second water and electricity core shaft connected to the positive electrode of direct current (second conductive half shaft 402 + second insulating half shaft 401) → second water-cooled cable 406 → generator anode;

[0093] After the cathode and anode are cooled, the two-way water converges and is connected to the return water system.

[0094] In a specific embodiment of the present utility model, the support device includes a first fixing plate 100 and a second fixing plate 200. Since the first fixing plate 100 is used to fix the conductive half shafts (first conductive half shaft 302 and second conductive half shaft 402), in order to avoid short circuit between the two conductive half shafts, the first fixing plate 100 is an insulating plate. Of course, both the first fixing plate 100 and the second fixing plate 200 can also be insulating plates.

[0095] The first fixing plate 100 is provided with first support holes respectively corresponding to two conductive half shafts (the first conductive half shaft 302 and the second conductive half shaft 402) and the gas core shaft 501 one by one. The second fixing plate 200 is provided with second support holes respectively corresponding to two insulating half shafts (the first insulating half shaft 301 and the second insulating half shaft 401) and the gas core shaft 501 one by one.

[0096] The second ends of the two conductive half shafts and one end of the gas core shaft 501 are supported in the first support holes corresponding to them respectively. The cable connectors of the conductive half shafts and the gas outlet connector of the gas core shaft 501 are located on the side of the first fixing plate 100 facing away from the second fixing plate 200.

[0097] The second ends of the two insulating half shafts and the other end of the gas core shaft 501 are supported in the second support holes corresponding to them respectively. The cable sockets (the first cable socket 308 and the second cable socket 408), the water pipe connectors of the two insulating half shafts (the first water pipe connector of the first insulating half shaft 301 and the second water pipe connector of the second insulating half shaft 401), and the gas inlet connector of the gas core shaft 501 are all located on the side of the second fixing plate 200 facing away from the first fixing plate 100. That is, in this embodiment, the connectors for connecting the generator auxiliary connection device to external devices are all arranged outside the support device to facilitate connection to external devices.

[0098] In order to prevent the first hydroelectric core shaft, the second hydroelectric core shaft and the gas core shaft 501 from rotating around their own axes after installation, in this embodiment, the first support hole is a polygonal hole, and the second ends of the two conductive half shafts and one end of the gas core shaft 501 have first prism parts that cooperate with the corresponding first support holes. Specifically, for the convenience of processing, the first support hole can be a regular polygon, such as a regular hexagon, a regular pentagon, etc.

[0099] Correspondingly, the second support hole can also be designed as a polygonal hole, and the second ends of the two insulating half shafts and the other end of the gas core shaft 501 have second prism parts that cooperate with the corresponding second support holes. Specifically, for the convenience of processing, the second support hole can be a regular polygon, such as a regular hexagon, a regular pentagon, etc.

[0100] Further, the first fixing plate 100 and the second fixing plate 200 can be arranged in parallel and fixed by a pull rod 600. The first fixing plate 100 and the second fixing plate 200 can both be rectangular plates, and pull rods 600 are respectively arranged at the four corners of the first fixing plate 100 and the second fixing plate 200 for fixation. The distance between the first fixing plate 100 and the second fixing plate 200 is determined by the lengths of the first hydroelectric spindle, the second hydroelectric spindle and the air spindle 501. Both ends of the first hydroelectric spindle, the second hydroelectric spindle and the air spindle 501 have prism parts (one end is the first prism part and the other end is the second prism part), and the outer dimensions of the parts except the prism parts at both ends are larger and cannot be inserted into the corresponding support holes. Therefore, the main parts of the first hydroelectric spindle, the second hydroelectric spindle and the air spindle 501 can be clamped between the first fixing plate 100 and the second fixing plate 200, and then the first fixing plate 100 and the second fixing plate 200 are tightened by the pull rod 600, so that the first hydroelectric spindle, the second hydroelectric spindle and the air spindle 501 can be fixed between the first fixing plate 100 and the second fixing plate 200.

[0101] The pull rod 600 can be a double-headed stud structure. Tightening holes for the pull rod 600 to pass through are opened on the first fixing plate 100 and the second fixing plate 200, and then it can be locked by a cap nut 601.

[0102] As Figure 2 shown, in a specific embodiment of the present utility model, the generator auxiliary connection device further includes a housing 700, and the housing 700 is covered between the first fixing plate 100 and the second fixing plate 200. A hollow state exists between the first fixing plate 100 and the second fixing plate 200. In order to protect the internal parts thereof, the housing 700 is specifically added, and the housing 700 wraps the hollow part between the first fixing plate 100 and the second fixing plate 200.

[0103] The housing 700 is a cuboid structure with through holes at both ends. The through holes at both ends of the housing 700 correspond to the first fixing plate 100 and the second fixing plate 200 respectively. The housing 700 is provided with a stop edge at the through hole at one end, and the through hole at the other end may not be provided with a stop edge. During installation, the second fixing plate 200 is pushed into the housing 700 from the through hole without a stop edge until the second fixing plate 200 abuts against the stop edge of the through hole at the other end, and then the housing 700 is fixed to the first fixing plate 100 by fasteners. The bottom of the housing 700 can be provided with feet to facilitate the placement of the housing 700.

The generator auxiliary connection device is the one disclosed in the above embodiment. The cable connector of one conductive half shaft is connected to one water-cooled cable of the plasma generator, and the cable connector of the other conductive half shaft is connected to the other water-cooled cable of the plasma generator. Since the plasma generator system provided by the present utility model has the above generator auxiliary connection device, it has all the technical effects of the above generator auxiliary connection device, which will not be elaborated herein again.
