A multifunctional portable barbecue oven
The utility model discloses a multifunctional portable barbecue stove, including one upper portion with the furnace body of opening, forms the furnace cavity in the furnace body, and the both sides in the furnace cavity are detachably provided with the charcoal box. It is completely different with the layout of the food material on the upper portion and the charcoal fire on the lower portion commonly used in the traditional barbecue stove, and it innovatively places the charcoal box on the both sides of the furnace cavity. In the barbecue process, the food material is placed at the opening of the furnace body, and since the charcoal box is located on the side, the oil dropped by the food material will not directly contact the charcoal fire, but will drop into the oil collecting box, avoiding the problem of a large amount of oil fume generated by the oil meeting the high-temperature charcoal fire in the traditional design, making the outdoor barbecue more healthy and more environmentally friendly, and improving the user's use experience. The upper portion of the furnace body is detachably provided with a support assembly, and the support assembly is provided with an automatic rotating assembly. The automatic rotating assembly can drive the food material to realize stable automatic rotating function, replacing the operation mode of manually frequently turning the food material, and significantly reducing the labor intensity of the user in the barbecue process.

Electrically driven regenerative open heat pump unit and heating system thereof
This invention provides an electrically driven open-type heat pump unit and its heating system, comprising an absorption tower, a low-temperature solution storage tank, an evaporator, a heat exchanger, a compressor, an expansion valve, a high-temperature solution storage tank, a condenser, a steam compressor, and a condenser. A dilute solution sequentially enters the high-temperature solution storage tank and the condenser, then enters the condenser for concentration. The concentrated high-temperature solution then enters the high-temperature solution storage tank, the heat exchanger, the low-temperature solution storage tank, and the absorption tower. The heat exchanger provides external heating. The steam generated during concentration enters the steam compressor, where it is pressurized and heated, serving as a heat source for the solution concentration process. Part of the solution in the low-temperature solution storage tank enters the evaporator for heat release and cooling. The refrigerant vapor generated in the evaporator is pressurized by the compressor and enters the condenser to heat the dilute solution. After condensation, the refrigerant vapor returns to the evaporator through the expansion valve, completing the refrigerant cycle. This invention is entirely electrically driven, increasing the external heating temperature and better meeting the heating needs of users. Furthermore, it decouples waste heat recovery, heat supply, and power consumption, making the system more flexible and efficient, and significantly reducing operating costs.

Pump station front pool drainage pressure reduction structure
This utility model relates to the field of water conservancy engineering pump station technology and discloses a seepage reduction and pressure relief structure for a pump station forebay, including: a forebay bottom slab, a seepage ditch, a pressure relief well, and a drainage hole. The forebay bottom slab is a reinforced concrete slab structure that connects to the inlet channel at the front and the pump station body at the rear. A filter layer and geotextile are laid sequentially on the lower part of the bottom slab. At the same time, the lateral extrusion of each layer is prevented by a deeply embedded retaining tooth wall around the perimeter, ensuring the stability and reliability of the filter layer. This utility model effectively reduces the seepage pressure in the pump station forebay by adopting multiple integrated measures, ensuring the stability of the station foundation seepage. The multiple safety defenses solve the problem of easy siltation and failure of traditional seepage reduction and pressure relief facilities, significantly improving the structural reliability and safety of the pump station forebay. The overall structure of the seepage reduction and pressure relief structure is simple in construction, flexible in operation, economical and efficient, and highly universal.
