The invention discloses an automatic graphite electrode paste feeding, traction operation and discharging system which is characterized in that a hopper for containing graphite paste is conveyed to asecond-layer platform from a first-layer platform and poured into a cooling machine; the conveying line comprises a first-layer conveying line body, a lifting rotating platform, a lifting conveying device and a second-layer conveying line body. Paste poured from a kneading pot is received by the hopper, the hopper is pushed to the lifting rotary platform through the first-layer traction head, thehopper rotates by 180 degrees to be separated from the first-layer traction head, the lifting rotary platform is conveyed to the second-layer platform through the lifting conveying device, and the hopper is pulled to the position above the material cooling machine through the second-layer traction head so that the hopper can be separated for discharging. Then, the operation is reversely repeated to finish one-time feeding; according to the invention, the probability of man-made mistakes is reduced, the safety coefficient is increased, the scattering of the paste is avoided, and the purity of the paste and the product quality are ensured.

The invention provides an intelligent mailbox system and a control method thereof. The intelligent mailbox system comprises a single-chip microcomputer system, an infrared induction system, a radio frequency identification unlocking system, a buzzer warning system, an LED display system, an independent power source system and a GSM communication system. The intelligent mailbox system and the control method thereof have the advantages that a short message is automatically sent to inform a user; when the system detects a letter, the user can be reminded in time, the user can conveniently fetch the letter fast in time, time is saved, and efficiency is improved; user identity authentication is achieved through radio frequency identification, the mailbox system is designed based on the VIP theory, each mailbox corresponds to a radio frequency card, the safety of the letter is improved, and the probability of losing the letter is greatly reduced.

The invention discloses a servo self-locking hydraulic reset mechanism of a servo self-locking reinforcement hydraulic oil cylinder. The servo self-locking hydraulic reset mechanism comprises a servoself-locking mechanism and a hydraulic reset mechanism; the servo self-locking mechanism comprises a retaining rod, a retaining ring and a disk spring; the surface of the retaining rod is provided with outer ratchets, and the outer ratchets on the surface of the retaining rod is meshed with inner ratchets of the retaining ring; the disk spring is arranged in the retaining ring; and the hydraulic reset mechanism is a reset small hydraulic oil cylinder and enables the servo self-locking mechanism to be separated so that the locking state can be removed through the reset small hydraulic oil cylinder. The servo self-locking hydraulic reset mechanism of the servo self-locking reinforcement hydraulic oil cylinder is provided with the servo self-locking mechanism and the hydraulic reset mechanism, the mechanical self-locking mechanism is large in locking force and safe and reliable in locking, the reset small hydraulic oil cylinder overcomes pulling of the compression force of the disk spring, the retaining ring moves towards the outer side so as to be separated from the part, engaged with the retaining rod, of the retaining ring, accordingly, the portion, connected with the other end ofthe retaining rod is drawn back freely, response is flexible and quick, and safety and reliability are achieved without manual control.

The invention discloses a flame-retardant power distribution cabinet with easy cable arrangement. The flame-retardant power distribution cabinet comprises a cabinet body. A mounting area, a flame-retardant box and a mounting plate are sequentially arranged in the cabinet body from top to bottom. A flame-retardant mechanism is arranged in the flame-retardant box. A plurality of second chutes are symmetrically arranged on the mounting plate, and each second chute is slidably provided with a first partition plate. The two sides of each second chute are provided with a first chute, and each firstchute is slidably provided with a second partition plate, and a first guide column and a second guide column are respectively formed on the side walls of a plurality of first partition plates and second partition plates. The first partition plate, the second partition plate and related accessories are arranged so that a plurality of cables can be conveniently arranged in the power distribution cabinet in a neat and orderly manner, and the maintenance personnel is enabled to find the position of the corresponding cable correspondingly. Meanwhile, when the cable in the power distribution cabinetis short-circuited and catches fire, the flame-retardant mechanism can quickly discharge the air in the power distribution cabinet, and thus the purpose of quickly extinguishing the fire can be achieved.
