Description

Special detachable waterproof sealed cabin body that floods of switch board Technical Field The invention relates to the technical field of power distribution cabinets, in particular to a detachable waterproof flooding sealing cabin special for a power distribution cabinet. Background The power distribution cabinet is characterized in that switching equipment, measuring instruments, protection appliances and auxiliary equipment are assembled in or on a closed or semi-closed metal cabinet according to the electric wiring requirements to form a low-voltage power distribution device, and the low-voltage power distribution cabinet is mainly used for controlling, distributing and protecting circuits and plays a vital role in an electric power system. During normal operation, the power distribution cabinet can switch on or off a circuit by means of a manual or automatic switch; when the circuit breaks down, the circuit can be cut off by utilizing a protection electric appliance or an alarm signal is sent out, so that the safe and stable operation of a power system is ensured. According to the patent document CN114421315A, the disclosed power distribution cabinet and power distribution cabinet group belong to the technical field of power distribution cabinets and comprise a power distribution cabinet body, wherein a plurality of drawer type electric boxes are movably connected to the inner cavity of the power distribution cabinet body through sliding seats, and wiring terminals are movably connected to the rear sides of the drawer type electric boxes. According to the invention, under the condition that the engaging rod and the supporting block are not limited by the rear terminal protection mechanism, the engaging rod can be unfolded and reset by the elasticity of the elastic sheet at one side to drive the pressing rod to rotate around the terminal limiting rod through the rear transmission sleeve, the front end conical part can be in clamping connection with the drawer type elevator box moving to the tail end and the tail end of the cable terminal under the action of rotation of the pressing rod around the transmission sleeve, the engaging rods oppositely arranged at two sides can realize staggered engaging fixation of the cable at the front part of the connecting terminal under the engaging action of the front end conical part, so that the phenomenon of clamping and unhooking of the connecting cable and the connecting terminal caused by external impact shaking is effectively avoided, and the assembly stability is effectively improved. The power distribution cabinet is used as a key electric power facility and is usually installed in an outdoor relatively wide and well ventilated area so as to facilitate heat dissipation and maintenance, however, the installation position also makes the power distribution cabinet particularly fragile when encountering severe weather conditions, especially in the case of heavy rain weather or sudden natural disasters, the power distribution cabinet is extremely likely to suffer direct attack of rainwater or rapid rising of peripheral ponding, so that the power distribution cabinet is submerged, and in this case, electric elements inside the power distribution cabinet face extremely high risks, are easily damaged due to water inflow, further influence the stability and normal operation of the whole power distribution system, and even possibly cause power interruption or other potential safety hazards. Disclosure of Invention In order to overcome the defects of the prior art, the invention provides the detachable waterproof flooding sealed cabin body special for the power distribution cabinet, and the technical problem to be solved by the invention is that the power distribution cabinet is very likely to suffer direct attack of rainwater or rapid rising of peripheral ponding under the condition of heavy rain weather or sudden natural disasters, so that the power distribution cabinet is submerged, and under the condition, electric elements in the power distribution cabinet are exposed to great risks and are easily damaged due to water inflow, so that the stability and normal operation of the whole power distribution system are affected, and even power interruption or other potential safety hazards are likely to be caused. In order to solve the technical problems, the invention adopts the following technical scheme: The detachable waterproof sealing cabin special for the power distribution cabinet comprises the power distribution cabinet, wherein a sealing mechanism is arranged on the inner wall of the power distribution cabinet, and a cavity is formed in the inner wall of the sealing mechanism; the sealing mechanism comprises a sealing group frame, and a sealing assembly is arranged on the inner side of the sealing group frame; The closed group frame comprises a closed shell, and fixing components are arranged on the left side and the right side of the middle part of the inner side
