High-voltage control system of tunnel marine organism collecting vehicle

Abstract

The invention discloses a high-voltage control system of a tunnel marine organism collection vehicle, which comprises a plurality of high-voltage control units respectively packaged in different box bodies of a protection level IP67 according to different functions, and each high-voltage control unit comprises a diesel generator unit, a power battery unit, a high-voltage control cabinet unit, a motor controller unit and a collection device control box unit; the beneficial effects of the invention are that all high-voltage control parts are respectively packaged in different box bodies with theprotection level of IP67 according to different functions, thereby forming all high-voltage control units, enabling all control units to be connected through cables with quick connectors, and avoiding the corrosion of a system caused by the moisture of marine organisms in a tunnel; a quick charging loop and a slow charging loop are integrated into one circuit, and a charging contactor K4 and a charging contactor K5 are set to be in a one-on-one-off structural form, so that the problem of flash explosion of hydrogen sulfide and ammonia gas in a tunnel caused by electric sparks generated by switching the quick charging loop and the slow charging loop when the circuit is not discharged thoroughly is avoided.

Description

Technical field: [0001] The invention belongs to the technical field of auxiliary equipment of nuclear power plants, and more specifically relates to a high-voltage control system of a vehicle for collecting marine organisms in a tunnel. Background technique: [0002] Tunnels are the main implementation of water diversion or drainage in nuclear power plants. Long-term use of tunnels breeds a large number of marine organisms, silt and other impurities; seriously affecting the normal operation of nuclear power plants. There are potential safety hazards when the work is done manually; [0003] The sea organism cleaning robot in the large water intake tunnel is mainly composed of cleaning robot, collection robot, remote control system and auxiliary equipment, etc. However, due to the large amount of sea organisms, silt and other impurities in the tunnel, the humidity in the tunnel is high and there are local residual harmful gases such as sulfur Hydrogen and ammonia, while the ...

[0002] Tunnels are the main implementation of water diversion or drainage in nuclear power plants. Long-term use of tunnels breeds a large number of marine organisms, silt and other impurities; seriously affecting the normal operation of nuclear power plants. There are potential safety hazards when the work is done manually;

[0003] The sea organism cleaning robot in the large-scale water intake tunnel is mainly composed of cleaning robot, collection robot, remote control system and auxiliary equipment, etc. However, due to the large amount of sea organisms, silt and other impurities in the tunnel, the humidity in the tunnel is high and some harmful gases such as sulfide Hydrogen and ammonia, while the existing cleaning robots all adopt a real-time charging mode, that is, when the battery voltage cannot meet the demand, the battery can be charged to meet the real-time demand by switching the fast charging circuit or the slow charging circuit; when the circuit discharge is not complete , it is easy to generate electric sparks, and it is easy to cause flash explosion if it encounters an open flame, and the operating conditions are relatively high. The power switching with the power battery pack should be reasonably controlled, safe and reliable
