The invention discloses a feeding mechanism with a culturing cage and a feeding through in a separated mode. The feeding mechanism comprises a culturing cage which extends along a length direction and is provide with a plurality of feeding mouths for animals to feed, at least one food groove corresponding to the feeding mouths, at least one feeding hopper for adding feeding to the feeding groove, a bearing mechanism for bearing the feeding groove, a driving mechanism for driving the bearing mechanism to make reciprocating movement along with the length direction of the culturing cage, and at least one feeding groove can correspond to all the feeding mouths within one reciprocating cycle. The feeding mechanism has the advantages of being low in production cost, increasing animal feeding, avoiding uneven feeding and the like.

Disclosed is a photovoltaic array using a photovoltaic module integrated board. The photovoltaic array using the photovoltaic module integrated board comprises at least two cross beams and at least two photovoltaic module integrated boards, the included angle between vertical axes of the at least two cross beams is smaller than 15 degrees, included angles between the vertical axis of at least one cross beam and vertical axes of the at least two photovoltaic module integrated boards are not smaller than 30 degrees and not larger than 150 degrees, and the total area of all photovoltaic module integrated boards supported by at least one group of cross beams is larger than 12 square meters. According to the photovoltaic array using the photovoltaic module integrated board, the design of sharing of cross beams, upright columns and foundation is used, materials and installing work hours are saved, and costs are greatly reduced.

The invention relates to a skid-mounted refueling device with a circulative heating function. The device provided by the invention comprises a separation explosion-proof oil tank with a cleaning groove, wherein a circulation heating pipeline loop is arranged in the cleaning groove, and can be used for effectively controlling the temperature in the tank, preventing diesel oil in the tank from being solidified to separate out paraffin wax caused by temperature reduction, and further lowering the installation quantity of the oil tank.

The invention discloses a tunnel fan used for tunnel construction, which comprises a base tube, the left and right ends of the base tube are movably connected with an air guiding pipe and an air collecting pipe, and the inner side walls of the air guiding pipe and the air collecting pipe are conical. The inner cylinder is sleeved with an inner cylinder, the outer wall of the inner cylinder is fixedly connected with a plurality of support plates, the right end of the inner cylinder is fixedly connected with a diversion cone, and the right end of the diversion cone runs through the dust cover And it extends to the inside of the air collecting pipe. There are multiple ventilation holes at the connection between the diversion cone and the inner cylinder. A motor is fixedly installed in the inner cylinder. A plurality of fan blades are fixedly connected to the output shaft of the motor, and the outer edge of the fan blade There is a sound-absorbing structure in a circle. According to the invention, after the gas enters the device, it will flow along the diversion cone, which reduces the resistance of the motor to the gas flow, and then makes the gas quickly flow between the base cylinder and the inner cylinder, and pass through the rotating diversion groove. Auxiliary to increase the pressure head and flow rate, improve the working efficiency of the device.
