A die head has a plunger and metering chambers. Uniform amounts of molten resins are supplied to a die head of an extruder, uniform amounts of the molten resins are discharged from the die head, and the timings of the discharge are uniformly controlled. A main-layer forming flow passage and a core-layer flow passage are formed in a die head. Metering chambers are provided in the main-layer forming flow passage and the core-layer flow passage, and molten resins are forced from the upstream of the flow passages into the main-layer forming passage and the core-layer flow passage by molten resin pumping force. Plungers retracted by the molten resin pumping force and discharging the metered molten resins to the downstream of the flow passage are installed in the metering chambers. The amounts of discharge of the molten resins by the plungers and the timings of the discharge are controlled by a control section for controlling the plunger.

The invention discloses a portable geological disaster monitoring device. A modular GNSS positioning module, a battery, a communication module and a battery manager are installed in an equipment box, and the equipment box is detachably fixed on a mounting base, and the bottom end of the mounting base is passed through a connecting rod. It is detachably fixed to the ground-drilling pile, and the ground-drilling pile includes a drill pipe. The two sides of the drill pipe are provided with inclined upward warps. In the middle, the structure is simple, lightweight and easy to carry, and at the same time it is solid and stable enough; when installing, the ground-boring piles are driven into the soil layer, and the warp pieces are in frictional contact with the soil. On the one hand, the ground-boring piles are prevented from being pulled up, and on the other hand, settlement , the structure is simple and lightweight, easy to carry, and at the same time strong enough and stable.

The invention discloses a self-powered sensor for monitoring flow rate of pipeline flow based on vortex-induced vibration. The self-powered sensor is characterized in that an inner cylinder is arranged at the inner wall of a pipeline of an outer cylinder, and leading line sealing plugs are arranged in the side wall of the pipeline of the outer cylinder; a bluff body, a sensor and an energy capturing unit are arranged in the inner cylinder; a vibration power generation sheet is clamped and fixed into the inner cylinder by a clamp assembly, and the end of the vibration power generation sheet isstuck onto an induced vibration board; mass blocks are vertically and symmetrically adhered to both sides of the induced vibration board; positive and negative leading lines of the vibration power generation sheet penetrate through the wall of the outer cylinder through the leading line sealing plugs, and are connected with an external circuit assembly. The self-powered sensor has the advantages that no external power source is needed, the online measuring on flow rate and the energy supply for a flow rate signal wireless transmission unit can be simultaneously realized under the action of fluid and solid coupling, and the online measuring on the flow rate in the pipeline is truly realized; by adjusting the self inherent frequency and the distance relative to the bluff body, the power supply capacity is increased, the structure is simple and miniature, the selection range of power generation functional materials is broad, the compatibility and extendability in the pipeline are strong,and the array layout and multi-point layout in the pipeline can be easily realized.
