The invention relates to an overwater balance vessel, comprising a carrier sealed chamber and a carrier platform; a left footboard and a right footboard are arranged on the carrier platform, pressure sensors are distributed on each of the left and right footboards, a controller, a miniature gyroscope, a battery and a power unit are arranged in the carrier sealed chamber, the power unit comprises a spray propeller, two circular water pipes, a plurality of rotary nozzles, a direct-current motor and pull rods, the inflow end and outflow end of the spray propeller are communicated with the two circular water pipes respectively, all the rotary nozzles are extended out of the carrier seal chamber and are evenly distributed into a coil, outlets of the rotary nozzles point to the radial outlet of the circle, each rotary nozzle is communicated with the two circular water pipes through an electromagnetic valve, and each rotary nozzle is connected with the direct-current motor through one pull rod. The overwater balance vessel commanded by stepping of an operator, has the functions of self-balancing, self-maintaining, accelerating, braking, forward driving, reversing, and turning, and is simple to operate and good in safety.

The invention discloses an agricultural product transport device. The device comprises a fruit tree planting ramp, a walking wheel rail is arranged above the fruit tree planting ramp, the extension direction of the walking wheel rail is parallel to the fruit tree planting ramp, a walking wheel unit is arranged on the walking wheel rail, the walking wheel unit can walk in the extension direction of the walking wheel rail, a left brake gear body does the centrifugal movement to be clamped between two adjacent inner gears on a left inner gear ring, a right brake gear body does the centrifugal movement and then is clamped between two adjacent inner gear bodies on a right inner gear ring, and therefore brake of the walking wheel unit can be achieved.

The invention discloses balanced exchange drive of non-hub motors of a high-energy-saving electric vehicle. The balanced exchange drive adopts four non-hub motors for driving simultaneously, wherein four non-hub motor controllers and one pedal hall accelerator control the four non-hub motors to regulate the speed of the four non-hub motors, so that the four non-hub motors work synchronously. The force received by the four non-hub motors is different at the same time when the electric vehicle turns, and electronic differential and self-adaptive control of two non-hub motors are realized by the four non-hub motor controllers, so that driving is safer. The balanced exchange drive has the advantages that (1) four non-hub motors are adopted as drive, so that the heat dissipation area of each non-hub motor is increased, the effective power of the electric vehicle is improved, tire burst caused by overheat is prevented, the anti-skid ability is improved, and the stability of the electric vehicle and the driving safety are improved; (2) the front or rear two non-hub motors respectively do not work because of some reasons, and the other two non-hub motors work, so that the electric vehicle can travel normally, and the normal driving reliability of the electric vehicle is improved; (3) the non-hub motors are special motors, and the motors, the power systems of which are integrated into hubs, and are named non-hub motors, so that the maintenance and the replacement are facilitated, and the tires are easily replaced; (4) the ABX electronic brake is achieved, mechanical brake is eliminated, and labor and materials are saved.

The invention discloses a self-locking type automobile emergency braking system, which is composed of a spring supporting seat, a fixing lock, a rope collecting roller, a sliding arc plate, a clamping plate, a friction plate and a tripod, and is arranged right above each driving wheel. According to the self-locking type automobile emergency braking system, an emergency braking button, which is arranged in a driving cab, is pressed when emergency braking is needed; the emergency braking button is used for controlling an electromagnetic valve switch to open an air reservoir, so that air pressure enters into a cylinder barrel body, which is fixed at the bottom part of an automobile frame, through an air circuit; a piston rod, which extends out of the cylinder barrel body, drives a lock pulling rod on the fixing lock to act, so that a locked retaining ring at the top part of a shock absorber is released; the front part of the sliding arc plate, which is integrally connected with the shock absorber, slips downwards by means of the own gravity; a combined body, which is formed by the friction plate and the clamping plate, slips in front of the wheel along the sliding arc plate, so that the braking is realized, and traffic accidents are effectively prevented. The self-locking type automobile emergency braking system is suitable for various types of vehicles, and is especially applied to heavy trucks and large vehicles.

A mechanical braking device based on a mechatronic self-locking system disclosed in the present invention includes a tooling seat, a transmission cavity is arranged in the tooling seat, a driving motor is fixedly arranged in the rear inner wall of the transmission cavity, and the transmission There is a brake assembly in the cavity, and a transmission cavity is connected to the left inner wall of the transmission cavity, and a plastic tube transmission and cutting assembly is installed in the transmission cavity, and the driving motor can be controlled by the brake assembly. The transmission of the plastic pipe transmission and cutting assembly, the brake assembly includes a first rotating shaft power connected to the front end of the driving motor, the first rotating shaft is connected with a first gear through a first spline connection assembly, and the first rotating shaft The lower end of a gear is meshed with the first ring teeth. This example aims to design a mechanical brake device that has a buffering effect and can shorten the reaction time gap used in the fixed-length cutting tool for pipelines.

The invention relates to the field of electric automobiles powered by storage batteries and particularly relates to a big wheeled vehicle with son-mother structure wheels. The big wheeled vehicle comprises a cubic vehicle body and further comprises an axle, two large-diameter wheels, two small-diameter supporting wheels, a main controller and storage batteries, wherein the axle penetrates along the length direction and is fixedly arranged on the vehicle body; the two large-diameter wheels are arranged at the two ends of the axle; the two small-diameter supporting wheels are mounted in front and back of the vehicle body respectively through retracting mechanisms. Compared with the prior art, the big wheeled vehicle has the following beneficial effects that (1) the large-diameter wheels are in a son-mother structure and are comprehensively controlled by the wheel controller, so as to intelligently realize typical traveling processes of starting, stably driving, accelerating, decelerating, braking and the like; (2) the axle does not rotate, and a driving part and a braking part are integrated in the wheels, so that the structure is compact.
