The invention discloses a barbecue grill and a barbecue mechanism, and belongs to the technical field of barbecue supplies, the barbecue grill comprises a main machine part and a supporting part, the area between the main machine part and the supporting part forms a barbecue area, the supporting part is used for supporting the root of a barbecue stick, and the main machine part is provided with a barbecue stick tip positioning part, a rotary power transmission part and a rotary power input part; a motor mounting area is further arranged on the supporting part, a transmission shaft mounting hole is formed in the motor mounting area, a driving motor is mounted on the face, back to the barbecue area, of the motor mounting area, and a transmission shaft is mounted in the transmission shaft mounting hole. The barbecuing mechanism comprises a driving motor, a transmission shaft and a grill, one end of the transmission shaft is connected with the driving motor, and the other end of the transmission shaft is connected with the rotary power input part. The driving motor is installed on the face, away from the barbecue area, of the supporting part, so that the driving motor can be closer to an operator, the operator can operate the driving motor more conveniently and does not need to wind to the position of the main machine part for operation, and operation complexity is reduced.

The application discloses a transmission device for power communication and relates to the field of cable bridges, which comprises a plurality of groove type bridges, the groove type bridges are connected with each other through connecting assemblies, mounting top plates are arranged on the top surfaces of the groove type bridges, wire laying plates are arranged at the inner bottoms of the groove type bridges, wire pressing assemblies and condensing assemblies are mounted on the mounting top plates, a plurality of air vents are formed in the two side surfaces of the groove type bridges, the two side interiors of the groove type bridges are hollow, and closing assemblies are mounted in the two side interiors of the groove type bridges. In the application, the connecting assemblies, the wire pressing assemblies, the condensing assemblies and the closing assemblies are matched, finally, the problems, such as insufficient heat dissipation protection of traditional bridges, moisture air intrusion into the bridges in humid and cold areas, and damage of water vapor to wire rods and bridge components, are solved, and the installation efficiency, cable operation stability and safety of the power communication transmission device are improved.

The utility model relates to a kind of heat pump water heater power supply control circuit, belong to heat pump control technical field.Through respectively adopting commercial power rectification, PFC and boost module and photovoltaic drive and photovoltaic boost module, so that two power supply can be adjusted to the required voltage of DC bus synchronously.In addition, by measuring output voltage and adjusting the proportion of output voltage and open-circuit voltage, efficient cooperation and stable power supply between power supply are realized, and then power supply for compressor using photovoltaic is realized.
