The invention discloses an intelligent power distribution cabinet with safe intelligent protection. The intelligent power distribution cabinet comprises an outer box, the inner bottom of the outer box is rotatably connected with a mounting shaft through a bearing base, the upper surface of the mounting shaft is fixedly connected with a first fixing plate, and the surface of the first fixing plate is fixedly provided with a circuit board. A heat dissipation mechanism for dissipating heat of the circuit board is arranged on the outer box, a power-off mechanism for powering off the circuit board when the circuit is aged and on fire is arranged on the mounting shaft, and an alarm mechanism for giving an alarm when the circuit is on fire is arranged on the upper surface of the outer box. The heat dissipation mechanism comprises a plurality of hinged plates; a groove is formed in the side wall, close to the top, of the outer box; the hinged plates are rotationally installed in the groove through pin shafts; vertical plates are connected between the hinged plates; and turnover plates are fixedly installed in the hinged plates. According to the invention, entering of dust and winged insects are reduced during heat dissipation, and the service life of the device is prolonged.

The invention discloses a medical nursing hair washing vehicle. The medical nursing hair washing vehicle comprises a sliding plate, the bottom of the sliding plate is provided with sliding wheels, a support column and telescoping fixed rods are sequentially arranged on the sliding plate from left to right, and the tops of the telescoping fixed rods are connected with an operation plate. A water tank and a sewage tank are arranged on the sliding plate, the central part of the operation plate is provided with a hair washing basin, and a water outlet in the bottom of the hair washing basin is connected with the sewage tank through a flexible pipe. A controller and a washing liquid box are respectively arranged at two sides of the operation plate, one end, of the surface of the operation plate, provided with the washing liquid box is provided with two hollow steel pipes, and one hollow steel pipe is provided with a loudspeaker. A heater and a temperature sensor are respectively arranged at the left side and the right side of the interior of a heating box, and a water pipe and a flexible pipe connected with the bottom of the heating box are connected through a rubber pipe, and the joint of the water pipe and the rubber pipe is provided with an electronic valve. The medical nursing hair washing vehicle can prompt the medical workers to pay attention to the water temperature, and the case that the water temperature is too high, the patient or the medical workers are scalded can be avoided.

The invention relates to a mining intrinsically safe car backing-up alarming device. More than four middle sound transmission holes, front mounting grooves and rear mounting grooves are formed on the circumference of the inner chamber of a casing; a cable connecting plug is hermetically mounted on a mounting base at the lower part of the casing; a horn is mounted on a rear window of the casing inan inverted manner; a waterproof diaphragm is hermetically mounted on the rear end surface of the casing through a pressure plate; a front cover is mounted at the front part of the casing; a transparent lid is hermetically mounted at a window of the front cover and forms a closed watertight seal cavity; a middle cover plate on which a circuit board, an alarm lamp and a camera are mounted is mounted on the front cover or / and the inner chamber wall of the casing; more than four front sound transmission holes at the front part of an annular groove on the front cover and the middle sound transmission holes on the casing are arranged in a staggered manner; drain holes are formed at the bottom of the annular groove; a rear cover with a spherical surface is mounted at the rear part of the casingand opposite to the waterproof diaphragm; and a cavity between the rear cover and the casing is communicated with the middle sound transmission holes and the front sound transmission holes to form sound channels. The mining intrinsically safe car backing-up alarming device has the advantages of reasonable structure, convenience and reliability in use and flushing resistance, and can dynamically capture video of the rear part of a vehicle.

The invention belongs to the technical field of textile machinery, in particular to an alarm mechanism for warp knitting machine yarn breakage, comprising a chassis, the bottom of the inner cavity of the chassis is fixedly connected with a drive box, the inner cavity of the drive box is provided with a support column, and the outer surface of the support column is socketed There is a slide plate, by setting the guide wheel, when the warp yarn breaks, the guide wheel loses the downward pressure, at the same time, the pressure spring drives the slide plate to slide upward on the inner surface of the chute under the reaction force, and the slide plate drives the support column to move upward, supporting The column pushes the first concave frame to move upward, the first concave frame drives the guide wheel to move upward, and at the same time, the support column drives the trigger plate to move upward through the drive slot, so that the trigger plate contacts the metal contact plate, so that the buzzer is energized, thereby achieving In order to improve the alarm effect, by setting the above structure, it has the advantage of alarming when the warp yarn breaks, thereby effectively reminding the staff.

The invention relates to a multifunctional circuit breaker. The multifunctional circuit breaker comprises a circuit breaker body; a shell is arranged on the outer side of the circuit breaker body in asleeving mode; four baffles are arranged on the top of the inner wall of the shell; a groove with a downward opening is defined by the four baffles; a groove opening of the groove is connected with amicro-motor through a supporting rod; an output shaft of the micro-motor is rotationally connected with a fan; a switch contact piece is arranged at one end, away from the fan, of the micro-motor; aconnecting rod which is hinged to the groove is arranged in the groove in a penetrating mode; a copper contact piece matched with the switch contact piece is connected to the hinged position; a temperature sensor, a PLC, a vertical sliding rod and a driving mechanism for driving the vertical sliding rod to move are symmetrically arranged in the shell; the PLC is connected with the temperature sensor and the driving mechanism; an output shaft of the driving mechanism is connected with the sliding rod; a first sliding chute and a second sliding chute are symmetrically formed in the upper side and the lower side of the shell; a transverse rod is transversely arranged on the sliding rod; and the end part, close to the groove, of the transverse rod is connected with the end part of the connecting rod. The multifunctional circuit breaker has a heat dissipation effect and can achieve a warning effect.
