The invention relates to an intelligent table top with a hidden plug board. The intelligent table top comprises a table frame, a table board is fixed to the table frame through a plugging-connection mechanism, the table board is of an empty shell structure, and adjustment mechanisms are symmetrically arranged on the front side and the rear side of the table board; and the table frame comprises anupper side foot frame and a lower side foot frame, and the upper side foot frame and the lower side foot frame are connected through a bearing. The following problems that in the using process of an existing table top with jacks, a, the positions of the jacks are fixed, the jacks cannot be moved according to the actual situations, the lengths of power lines of electric appliances used are different, an external line is need for connecting the electric appliances, and potential safety hazards exist; and b, a table body is troublesome in disassembly and large in occupied space, the table body isdisassembled and assembled frequently by using tools, consequently assembled parts are prone to being abraded, and the service life of a table is shortened can be solved; and the function that a table with the jacks is intelligently adjusted and disassembled can be achieved.

An efficient energy-saving and multipurpose solar water heater comprises a hot water storage tank, an evaporation water tank, a preheating water tank, a distilled water tank and a full glass double-vacuum solar collector tube, wherein a vapor heat exchanger and a domestic hot water exchanger are installed in the hot water storage tank; an assisting electrical heating pipe and a flow deflector areinstalled in the evaporation water tank; a distilled water exchanger is installed in the preheating water tank; a tap water inlet heat exchanger is installed in the distilled water tank; the tap waterinlet heat exchanger, the preheating water tank and the domestic hot water thermal exchanger are communicated with each other in sequence, so as to provide domestic hot water for users; the full glass double vacuum solar collector tube is communicated and connected with the evaporation water tank; and the evaporation water tank, the vapor heat exchanger, the distilled water heat exchanger and thedistilled water tank are connected and communicated with each other in sequence, so as to provide drinking distilled water for the users. The invention has the advantages of novel structure, high heat efficiency, energy conservation, multiple purposes and excellent technical performance.

The present invention relates to a propeller cap structure. The present invention discloses a composite propeller cap for reducing swirling flow and propeller hub vortex and improving propulsion efficiency and having guide fins. The problem of the existing PBCF (Propeller Boss Cap Fin) which increases the manufacturing difficulty and causes the production cost to be increased due to precision machining, the present invention discloses a method of combining a diffusion type (contraction type) propeller hub cap end on the existing contraction type (contraction type) Diffusion type) propeller hub cap to reduce the hub vortex cavitation occurred in the rear of the propeller composite type propeller hub cap, and, by virtue of the constriction part of the propeller cap or between the constriction part and the diffusion part set plate (plate) form guide fin (guide fin) to further reduce the occurrence of hub vortex cavitation.

The invention relates to an improved motor rotor, which includes a rotor bracket, a rotating shaft, a rotor yoke, an installation unit and a permanent magnet. Two rotor brackets are symmetrically arranged and connected by bolts, and the middle of the two rotor brackets is A rotating shaft is fixedly arranged, and a rotor yoke is fixedly arranged on the outer edge of the rotor bracket. Several installation units are jointly arranged on the rotor bracket and the rotor yoke along the circumferential direction thereof, and permanent magnets are symmetrically installed on each installation unit. The present invention can solve the following problems in the current design of the motor rotor: the permanent magnets on the rotor yoke are all bonded by glue, and it is difficult to realize rapid disassembly and reinstallation, resulting in a decrease in the production and maintenance efficiency of the rotor; The number of permanent magnets on each rotor yoke is not small, and for the later maintenance of the rotor, one or more permanent magnets cannot be disassembled at the same time.
