The invention discloses a multi-core-driven multi-stage booster combined fire-extinguishing and smoke-controlling device which comprises a carrier. The carrier is provided with a rotating lifting mechanism which is fixedly provided with a combined exhaust blower group, the carrier is also provided with a control system which is connected with the combined exhaust blower group formed by assemblingand fixedly mounting six exhaust blowers together, and the six exhaust blowers are arranged up and down and integrally combined in two rows with three exhaust blowers in a row and share an outer air duct, a water supply pipeline and a water mist nozzle. The multi-core-driven multi-stage booster combined fire-extinguishing and smoke-controlling device of the invention has great exhaust air rate incase of a certain volume.

The invention provides a method for disassembling a bending tool and a rotor retaining ring, which can apply a pulling force consistent with the deformation direction of a bent workpiece. In the bending tool: the sliding seat is slidingly fitted with the support; the hook seat is rotatably connected with the sliding seat; the hook includes a rod that is slidingly fitted with the hook seat and a hook for hooking the workpiece to be bent; the length of the rod The direction is perpendicular to the bending rotation center line of the workpiece to be bent, the sliding direction of the rod relative to the hook seat is along the length direction of the rod, the sliding direction of the sliding seat relative to the support intersects the length direction of the rod and is in line with the bending direction. The center line of rotation is vertical, and the axis of rotation of the draw hook seat relative to the sliding seat is parallel to the center line of bending rotation. The decomposition method of the rotor retaining ring adopts the bending tool, including: hooking the hook to the bendable block; operating the hook to pull the bendable block to bend, adjusting the position of the slide seat relative to the support during the bending process, The position of the rod relative to the hook seat and the angle of the hook make the hook perpendicular to the bendable blocking piece.

The invention discloses a semi-automatic clutch device, which comprises a main shaft seat, a clutch and a connecting rod. The head end of the rod is hinged with the bearing seat and the middle part is fixedly connected with the clutch upper plate. The end of the connecting rod is equipped with a locking assembly, which locks the clutch upper plate and the clutch lower plate by pressing the connecting rod. When the driven part is overloaded When the clutch upper plate and the clutch lower plate overcome the pressing force of the locking assembly and separate, the present invention has the advantages of prolonging the service life of the power components, compact structure, simple operation, safety and reliability.

The invention relates to a reliability detecting method for a multi-channel power transmission device. The reliability detecting method is achieved through a reliability detecting system. The reliability detecting system comprises a control computer, a multifunctional measuring unit, a multiplexing module, a junction device and an adjustable direct current power source. The method is used for detecting the reliability of the dynamic contact resistance of the multi-channel power transmission device of a high-precision inertia instrument, whether the power transmission device makes good contact or not is judged according to reliability detecting data, the installation of the power transmission device is further adjusted, and the purpose of accurately transmitting signals is achieved. By means of the method, quick and accurate measuring and reliability detecting on the small dynamic resistance of a multiplexer channel of the power transmission device are achieved, and the adopted reliability detecting system is high in integration level, measuring precision and automation degree, easy to operate, safe and reliable.

The invention discloses a chip encryption method, which comprises the following steps: obtaining the fuse value and trimming value of each chip, and setting an algorithm; using the fuse value and trimming value as algorithm parameters, and using the algorithm to calculate the value of each chip The secret key, the secret key of each chip is unique; the fuse value, trimming value and secret key of each chip are written into the corresponding chip. In the chip encryption method of the present invention, since the fuse value and trimming value of each chip are naturally unique, it can ensure that the same matrix is ​​used in different applications or the same application. The keys are completely different. Even if an attacker cracks a chip, he can only get the key and application of the chip, and can only copy the single chip. If he wants to crack in batches, he must crack each chip in the batch of chips separately. Greatly increasing the cost and difficulty of the cracker, it loses the meaning of cracking. In this way, the intellectual property rights of users are protected to the greatest extent.

The invention relates to an intelligent power distribution cabinet for a power system. The intelligent power distribution cabinet comprises a cabinet body and a hoisting mechanism which is arranged above the cabinet body. The cabinet body is provided with a cabinet door. The front surface of the cabinet door is provided with an input / output mechanism and a handle. The back surface of the cabinet door is provided with a fixing mechanism. The cabinet body is internally provided with two horizontally arranged cross bars. The intelligent power distribution cabinet for the power system utilizes a third driving motor in the hoisting unit for making a conveyor belt move, and a moving block is driven to perform displacement, thereby making a suspension ring move in a trough, and facilitating hoisting operation and conveying operation on the suspension ring. Furthermore, a connecting board is horizontally arranged through a first connecting driving motor, thereby facilitating opening of the cabinet door. Through rotation of a second driving motor, a block on the connecting board approaches and clings to cross bar, thereby realizing locking operation on the cabinet door. The fixing mechanism realizes simple operation, high safety and high reliability, so that practicability of the power distribution cabinet is improved.
