The invention relates to a high-voltage and large-current plug and a high-voltage and large-current connector equipped with the plug. The high-voltage and large-current plug comprises at least two sleeve-shaped pins. The tail of each pin is used for inserting a shunt cable. The middle of each pin is embedded into a plug A rubber core. The head of each pin is detachably inserted into a plug B shunt substrate contact piece of a plug B. The plug B shunt substrate contact piece is embedded into a plug B shunt substrate. The plug A rubber core is installed in a plug A shell. Contact resistance produced when the high-voltage and large-current plug is plugged into a main conductor device of a power supply at the plug B side can be reduced.

The invention discloses a lashing process for transporting overrun goods by waterway. The goods are provided with a plurality of fastening points, and a plurality of universal boards are arranged at fixed intervals on the deck of the ship, and N Layer connectors and multiple steel ropes, one end of a steel rope is detachably connected to a fastening point, the other end is connected to a connector of the first layer and can rotate relative to the connector, each connection of the last layer of connectors All parts are detachably connected to the corresponding number of universal boards on the deck through multiple steel ropes; and when N>1, among the connecting parts of two adjacent layers, each connecting part of the upper layer is connected through multiple steel ropes In this way, the lashing of out-of-limit cargo can be realized, so that the lashing operation is fast, and the loss of materials and labor is greatly reduced, and the damage to the ship's splint is avoided, and open flame welding and fastening are also avoided. point of fire safety hazards.

The invention discloses a cotton picking spindle which comprises telescopic cotton picking needles through a series of structure design. The cotton picking needles stretch out when the cotton picking spindle is used for picking cotton, so that cotton can be picked when the cotton picking spindle rotates at low speed, and after cotton picking, the cotton picking needles draw back, so that the process of removing cotton is easy. Moreover, the cotton picking needles can be made of plastics instead of metal of traditional cotton picking needles, and therefore cost is greatly lowered. The cotton picking spindle effectively solves the problems that the cotton picking spindle of an existing cotton picking machine has potential safety hazards of fires, and cotton quality is lowered, greatly lowers cost, and creates a new conception and a new field of design of cotton picking machines.

The invention discloses an elevator control system and elevator equipment. The elevator control system includes a light curtain data acquisition module, a light curtain imaging drawing module, an electric vehicle identification module and an elevator work control module; the light curtain data acquisition module is used to acquire light The signal received by each receiver of the curtain; the light curtain imaging drawing module is used to draw an image according to the signal obtained by the light curtain data acquisition module; the electric vehicle identification module is used to compare the image drawn by the light curtain imaging drawing module with the image in the database Set the images for comparison to identify whether it is an electric vehicle; the elevator work control module is used to control the running state of the elevator equipment according to the identification result of the electric vehicle identification module. The elevator control system and elevator equipment proposed by the present invention can monitor the situation of the battery car entering the elevator in real time, and ensure that the imaging situation of the electric car entering the elevator can be accurately displayed when the electric car enters the elevator; the elevator occupant can be prompted to prohibit the electric car from going upstairs, thereby Ensure the fire safety of residents.

The invention relates to a deformation monitoring device, a deformation monitoring method and a granary deformation monitoring system, and the deformation monitoring device, the deformation monitoring method and the granary deformation monitoring system are used for solving the problems that the automation degree of an existing granary deformation monitoring device is low and cost is high. The deformation monitoring device is characterized by comprising at least a set of laser communication devices, each set of laser communication devices is composed of a drive module and a response module corresponding to the drive module, and the drive module and the response module are respectively provided with a laser for transmitting laser signals and a photoelectric converter used for receiving the laser signals. By the adoption of the laser linear transmission principle, the problem of granary body structural deformation which is difficult to monitor is solved; practical-circuit-free data transmission between the monitoring position and a primary control circuit can be achieved, and fireproof potential safety hazards caused by circuit arrangement and control are avoided.

The invention discloses a bracket prefabricated reinforcement framework of a pseudo-classic building, a fabrication method of the reinforcement framework, and a construction method of a reinforced concrete bracket of the pseudo-classic building. The bracket prefabricated reinforcement framework is a whole reinforcement cage consisting of an embedded part system, a bracket framework reinforcement system and a bracket stirrup; the embedded part system comprises a two-sided rectangular steel plate embedded part and a single-sided rectangular steel plate embedded part; the bracket framework reinforcement system comprises a bottom main rib, a middle main rib, an upper main rib and a surface rib; and the bracket stirrup is an annular reinforcement hoop formed by bending minor-diameter round steel. The fabrication method of the reinforcement framework comprises the steps of serving the two-sided rectangular steel plate embedded part as a temporary support system, penetrating, welding and fixing the bracket beam main ribs to form the reinforcement framework, and finally mounting the stirrup and the single-sided rectangular steel plate embedded part outside the reinforcement framework to form the whole reinforcement cage. The bracket reinforcement framework fabricated by the method is reliable in quality; and the construction method of the reinforced concrete bracket of the pseudo-classic building is high in working efficiency and high in safety coefficient, and saves a construction period.
