The invention discloses a convenient, light-weight and adjustable large-tonnage cable laying apparatus. A shaft rod is arranged at the upper ends of two side brackets; the shaft rod is provided with a cable drum; a guiding sleeve is arranged at the upper end of each side bracket separately; a lifting rod is arranged in each guiding sleeve in a sleeving manner; the lower end of each lifting rod is connected with a piston rod of a hydraulic cylinder; the upper end of each lifting rod is connected with the lower end of a bearing support; the shaft rod is provided with two bearings which are placed in upper end grooves of two bearing supports respectively; a brake wheel disc is mounted at one end of the shaft rod; the bake wheel disc is matched with a brake mechanism; the brake mechanism comprises a brake sheet and a screw crank arm; a positioning hoop is arranged on the shaft rod at the other end of the cable drum; and the shaft rod is provided with an arm shifting rod. The convenient, light-weight and adjustable large-tonnage cable laying apparatus is convenient and light-weight in operate; after the bearings and the fixed loop are mounted, the mechanical friction is almost zero; and the drum rotates freely and uniformly without generating noise, so that the problem of left and right swinging of the drum is solved.

The invention provides a strong breeze resisting minitype wind driven generator which comprises a generator main shaft, a blade, a shell, a generator rotor and a generator stator, wherein the blade is fixed on the generator main shaft; the shell supports the generator main shaft through a bearing; the shell comprises a stator shell, a front end cover which is positioned at the front end of the stator shell and a rear end cover which is positioned at the rear end of the stator shell; the generator rotor is positioned in the shell and fixed on the generator main shaft; the generator stator is fixed on the inner surface of the stator shell of the shell, corresponding to the generator rotor. The wind driven generator is characterized by also comprising a controller and a mechanical electromagnetic brake which are connected, wherein the mechanical electromagnetic brake is installed on the generator main shaft; and the controller is used for controlling the mechanical electromagnetic brake to brake. The strong breeze resisting minitype wind driven generator provided by the invention can not be forced to rotate by strong breeze, thus the safety of the minitype wind driven generator is ensured.

Disclosed is a full-power acceleration type impeller and architecture system, comprising an impeller acceleration system, a generator (21) and an architecture system. The impeller acceleration system converts external wind energy into the rotational kinetic energy and transmits the rotational kinetic energy to the generator (21), and the generator (21) converts the rotational kinetic energy into the electrical energy output by the system. The system improves on the imperfections of the narrow pipe wind-gathering power generation technology and the direct-driven acceleration type mechanical impeller structure, increases the compatibility, safe reliability, stability and service life of an enhanced composite bridge-type rigid crosslinking installation platform structure system, and reduces the volume, weight and cost of the generator.

The invention discloses a reset slide valve type rocker arm mechanism for engine braking and a braking method thereof. The reset slide valve type rocker arm mechanism for engine braking comprises a control mechanism, an oil filling mechanism, a rocker arm body and a driven mechanism, wherein the rocker arm body is provided with the control mechanism, the oil filling mechanism and the driven mechanism. According to the braking method, the switching of the working modes of an engine is controlled by controlling on-off of an external electromagnetic valve; when the electromagnetic valve is switched on, the engine enters the braking mode, a control valve core in the control mechanism is pushed by high-pressure oil to move downwards, and then a slide valve core is further made to move downwardsunder the action of spring force to isolate an oil supply channel from a pressure oil channel; and the driven mechanism forms a closed space and is pushed to move by oil in the oil channels in the closed space under the action of a cam, and then an exhaust valve directly connected with the driven mechanism is opened to release compressed gas, so that effective engine braking is generated, and thespeed of a vehicle is slowed down. The reset slide valve type rocker arm mechanism for engine braking is high in integration level, simple to control, and reliable and effective.
