Fully-automatic mahjong machine

The invention relates to a fully-automatic mahjong machine comprising a board sending system, a board loading system, a board lifting system and a large shuffling disc. The board sending system comprises four board sending mechanisms, each board sending mechanism comprises a transmission rack, and a board sending motor, a board absorbing wheel, a transmission belt, a transmission platform, a board inlet guiding piece and a board outlet guiding piece fixed on the transmission rack; a board sending channel is arranged at the upper end of the transmission platform, the board absorbing wheel is tightly attached at the lower end of a board inlet opening of the board sending channel, the board inlet guiding piece is positioned above the board absorbing wheel, the board outlet guiding piece is positioned at a board outlet opening of the board inlet channel, the board sending motor is used for driving a motor guiding wheel, the motor guiding wheel is positioned below the transmission platform, and the transmission belt loops the motor guiding wheel, the board absorbing wheel and the transmission platform. In the invention, for the mahjong boards with different widths, the board sending mechanism of the mahjong machine can run normally by only replacing the corresponding board inlet guiding piece and the board outlet guiding piece, and a transmission rack cover does not need to be changed, so that the operation is simple and convenient, and the board inlet guiding piece and the board outlet guiding piece has extremely low production cost relative to the transmission rack cover.

River way multipoint water quality monitoring apparatus and monitoring method therefor

The invention mainly discloses a river way multipoint water quality monitoring apparatus and a monitoring method therefor. The monitoring apparatus includes a monitoring body, a power apparatus and water collectors. A solar cell panel, a storage battery and a protective cover are disposed on the top surface of the monitoring body. At least three water collectors are disposed under the monitoring body through telescopic rods. A water storage chamber is arranged in each water collector. A water collection port is arranged on the bottom of each water collector and is provided with a sealed cover. A sampling tube is disposed in each telescopic rod. A detection chamber provided with a detection head and a wireless communication module are arranged in the monitoring body. One end of the sampling tube is connected to the water storage chamber. The other end of the sampling tube is connected to a splitting pipe through an electromagnetic valve. The splitting pipes are connected to the detection chamber. The monitoring apparatus is used for performing multipoint auto-monitoring to a to-be-detected water area for a long time instead of manual work. The monitoring apparatus is environment-friendly and economical, has sufficient energy and has wide detection range, can detect multiple water points at the same time and can get many detection data. Water collection and detection are separated into two independent parts, so that damage on the detection head due to aquatic animals is avoided, quality and service life of the monitoring apparatus are improved, and detection accuracy is increased.

Novel ceramic coating polyolefin composite film and preparation method thereof

The invention relates to a novel ceramic coating polyolefin composite film which comprises a polyolefin substrate with micro pores, wherein one side or both sides of the polyolefin substrate is/are compounded with ceramic coating(s); the ceramic coating comprises porous ceramic particles, an inorganic filler and an adhesive. The invention also relates to a method for preparing the novel ceramic coating polyolefin composite film. The method comprises the following steps: a, dissolving the adhesive in a solvent, thereby preparing an adhesive solution; b, adding the porous ceramic particles and the functional inorganic filler into the adhesion solution prepared in the step a, and performing dispersing treatment, thereby preparing coating slurry; and c, coating one or two surfaces of the polyolefin substrate with the coating slurry prepared in the step b, and drying and curing to prepare the product. The novel functional composite film has high liquid absorption and retention performance, has the functions of reducing harmful gases inside a battery, improving the performance of the battery and prolonging the service life of the battery, and has the safety characteristics of low closed pore temperature, high melting temperature and low hot-shrinkage rate.
