Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] The invention includes a sealing mechanism, a transmission mechanism, a self-balancing mechanism and a volume fine-tuning mechanism.
[0016] The sealing mechanism is made of PVC threaded pipes, which are screwed together by two internally threaded PVC pipes and three externally threaded PVC pipes to form a hollow pipe. A PET threaded sealing cap is screwed on the top of the pipe to ensure isolation from the outside world. The bottom end is covered with a leather bag and tied with a rubber band.
[0017] The transmission mechanism is composed of a screw rod, a copper nut, a stainless steel square tube, an acrylic plate, a syringe piston and a syringe. The source power of the transmission mechanism comes from the motor, and the motor is fixed inside the first internal threaded pipe and mounted on the internal acrylic plate, the thickness of the a...

The invention relates to a drift submerged buoy demonstration teaching aid. The drift submerged buoy demonstration teaching aid includes a manual fine-tuning mechanism for controlling storage and maximum volume of a component, a straight push rod mechanism and a volume automatic-change mechanism. The manual fine-tuning mechanism for controlling storage and maximum volume of the component comprises a PET (polyethylene glycol terephthalate) screw cap, a PET screwed pipe with the bottom drilled with holes, a PVC (polyvinyl chloride) screwed pipe, a nut and a rubber washer. The straight push rod mechanism comprises a DC (direct current) geared motor, a motor frame, an elastic coupling, a push rod unit, a double head threaded pipe clamp and a screw thread pipe. The volume automatic-change mechanism comprises a double head threaded pipe clamp, a piston, a water storage chamber, a rubber gasket, an acrylic pressure ring, an outer tooth joint and a leather bag. The drift submerged buoy demonstration teaching aid has the advantages of being capable of intuitively and simply show the ups and downs working principle of a submerged buoy and convenient to understand and learn.
Description
technical field [0001] The invention belongs to the field of teaching instruments, and in particular relates to a drifting submersible mark demonstration teaching aid. Background technique [0002] People have been exploring the ocean for hundreds of years, and the ocean drifting submersible is one of the more important tools for ocean exploration in recent years. It has the characteristics of unattended long-term, continuous, synchronous and automatic comprehensive monitoring of various elements of marine hydrology and meteorology under harsh marine environmental conditions. Time extension is an important means of offshore monitoring. However, as the submersible mark occupies such an important position in the marine industry, there is no market and patent for submersible mark teaching aids at home and abroad, and the network resources are relatively scarce. create certain difficulties. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the ...
