The invention provides a nuclear fuel assembly grid with enhanced mixing blades, wherein an upper rigid dimple and a lower rigid dimple and a spring between the upper rigid dimple and the lower rigid dimple are arranged on the side wall of each grid strip to clamp a fuel rod; a slot is formed below or above each grid strip, and the adjacent grid strips are connected in a vertical crossing manner through the slots; two corresponding enhanced mixing blades are arranged above a cross point of each two adjacent grid strips to mix fluid flowing by; each enhanced mixing blade is of a closed structure; a cavity is arranged on an axis wire which is within the range of 1-20 mm below the cross point of each two adjacent grid strips, and the grid strips are fixed through welding at the cavities. A closed area is formed at the cross part between each enhanced mixing blade and each strip, so that the mixing disturbance of the mixing blades on the fluid is remarkably improved. As the welding cavity is arranged below each mixing blade, the overall mechanical strength of the mixing grid is guaranteed.

The invention relates to the field of vehicle engineering, and provides a compressor, an air conditioning system and a vehicle.

The first threaded post is rotated on the bit block, and the two ends of the first threaded post are symmetrically threaded with adjusting nuts; the upper end of the second mounting base is threaded with a third threaded post, and the front end of the third threaded post is rotated with an adjusting connecting rod , the end face of the adjustment connecting rod is hinged on the adjustment slide plate; the invention solves the problems that the traditional device is difficult to transport when the road is damaged and difficult to fix in the field.

In each of a plurality of stages, an input analog signal is quantized, so that a digital signal corresponding to each part of bits is generated. ADA conversion portion generates an analog reference signal based on the digital signal, and a remainder operation portion performs addition / subtraction and amplification by a predetermined factor with respect to the input analog signal. Then, the signal thus obtained is supplied to a subsequent stage. The DA conversion portion in the first stage where A / D conversion of a plurality of bits is performed includes primary voltage supply portions capable of outputting a reference voltage at one of a plurality of levels, and an auxiliary voltage supply portion capable of outputting a reference voltage at an auxiliary level different from the above-described level. The respective voltage supply portions selectively output the reference voltages based on a digital signal generated by an AD conversion portion. Based on a combination of the output reference voltages, the analog reference signal in accordance with the digital signal is generated. It is possible to reduce power consumption while suppressing an increase in the area of an element.

The present invention relates to the technical field of charging piles, in particular to a canopy for charging piles that is retracted and folded. It includes an overturned fluid blocking device and an overturning plate arranged at the bottom of the overturned fluid blocking device to support it. In the present invention, rainwater is blocked by the resistance effect of the storage plate, so as to prevent the rainwater from directly contacting the charging column at the bottom thereof, thereby preventing the solar panel installed outside the solar panel from being damaged due to water ingress, so as to prevent the solar panel for the charging pile from raining. In addition, it is stored through the storage cavity to save the occupied area of ​​the storage board, and at the same time, there is no shelter on the top of the charging pile after storage, so as to provide enough irradiation area for the solar panels installed outside it, and then Solve the problem that the general rain shelter reduces the irradiation area of ​​the solar panel.
