    Abstract: The present invention provides a telescopic jacking stepwise rollback-type reel sprinkling irrigation machine, including a chassis, a locking-type reel, a sprinkling irrigation apparatus, and a stepwise driving apparatus. A locking channel in a circumferential direction is disposed on the locking-type reel. The stepwise driving apparatus includes a lifting cylinder, an upper caliper, and a lower caliper, and the upper caliper and the lower caliper are clamped to be mounted on the locking channel. Pressurized water is used in the telescopic jacking stepwise rollback-type reel sprinkling irrigation machine to drive the lifting cylinder to realize periodic lifting motion of the piston rod, so as to drive the upper caliper to move up and down to be engaged with the locking channel of the locking-type reel intermittently, thereby driving the locking-type reel to roll back intermittently to automatically reel in a sprinkling irrigation PE hose.

    Abstract: An eccentric swinging stepwise rollback-type reel sprinkling irrigation machine includes a chassis, a locking-type reel, a sprinkling irrigation apparatus, and a stepwise driving apparatus. A locking channel in a circumferential direction is disposed on the locking-type reel. The stepwise driving apparatus includes a water turbine gearbox, an eccentric swinging mechanism, an upper caliper, and a lower caliper. The upper caliper and the lower caliper are clamped to be mounted on the locking channel. A water turbine is used in the eccentric swinging stepwise rollback-type reel sprinkling irrigation machine to drive the eccentric swinging mechanism to realize an eccentric swing, so as to drive the upper caliper to move up and down to be engaged with the locking channel of the locking-type reel intermittently, thereby driving the locking-type reel to roll back intermittently to automatically reel in a sprinkling irrigation PE hose.

    Abstract: A hoist main shaft torque monitoring device based on angle measurement, constituted primarily by a first base, a second base, a light generating unit, a shutter, and a light sensing element; the light source, a first lens, and a first optical aperture arranged in the light generating unit, as well as a second optical aperture, second lens, and light sensing element on the shutter, forming a light source generation, propagation, and reception pathway; when the elevator main shaft is subjected to a certain torque, a corresponding displacement is produced between the first optical aperture and the second optical aperture, thus measuring the change in amount of light ultimately reaching the second optical aperture so as to measure the twist angle of the rotary shaft and finally calculate the magnitude of the shaft torque. Without damaging the original equipment and foundation, the device measures the torque of the shaft at different rotational speeds. The device can measure stationary torque and torque at different rotational speeds of the shaft, without the electromagnetic field interfering with wireless transmission; the device is easy to use, maintenance costs are low, and it is of interest for widespread popularization.
