Description

Technical Field

[0001] This invention relates to the field of ancient Chaitang relocation, restoration and protection technology, specifically to a mobile multi-angle liquid nitrogen spraying system for the relocation of ancient Chaitang. Background Technology

[0002] Seawalls are man-made dikes that block tides and serve as a barrier against the tides on both sides of the plains at the mouth of the Qiantang River.

[0003] The construction of the Class III waterway improvement project of the Beijing-Hangzhou Grand Canal in Zhejiang Province involves the Hangzhou Linping Seawall, a provincial-level cultural relic protection unit in Zhejiang Province. This section of the seawall is connected in a line, and the waterway cannot avoid it. Therefore, 90 meters of the seawall within the area need to be relocated.

[0004] The main body of the firewood pond is constructed by ramming alternating layers of earth and firewood, with wooden stakes driven into the pond and its base. The water-facing side of the pond is constructed of rammed earth and firewood, with the firewood bundled together. The cross-section is trapezoidal, rising 5 to 6 meters above the ground, and the base width varies from 12 to 21 meters.

[0005] Adhering to the principles of preserving the original materials, original form, original craftsmanship, and not altering the original state of the cultural relics, the Chai Tang site needs to be cut into 3m*3m small pieces. After cutting, these pieces will be moved into steel enclosures and then relocated to a designated area for protection and display, creating a seawall-themed heritage park.

[0006] Ensuring the straightness of the cut surfaces of the diced pieces over a long period is a major challenge. This requires freezing the surfaces by spraying liquid nitrogen, but due to the large size and wide cut surfaces of the diced pieces, suitable and easily disassembled and transported equipment is unavailable.

The locking bracket clamp 5411 deforms under the action of the clamping concave surface 5416, and the two anti-slip clamps 5412 approach each other, thereby clamping the spray pipe 542. The spray pipe 542 is connected to the liquid nitrogen storage tank in the control cabinet 3 through a hose. The spray units on the two sides, top, near end, and far end are assembled in sequence, thus completing the system assembly. The vertical movable column 53 is driven by multiple side folding units 52 to sweep along the side of the cut block. The cut blocks are frozen by spraying liquid nitrogen on the sides using the side spraying unit 54, and by sweeping the movable crossbeam 73 along the top surface using multiple top folding units 72. The top surface spraying unit 79 then sprays liquid nitrogen on the top surface of the cut blocks to freeze them. The cut blocks are also frozen by spraying liquid nitrogen on the two end surfaces using multiple end folding units 74, which in turn sweep the near end surface movable beam 75 and the far end surface movable beam 77 along the two end surfaces. The near end surface spraying unit 76 and the far end surface spraying unit 78 then spray liquid nitrogen on the two end surfaces of the cut blocks to freeze them. This ensures that the cut surface of the cut blocks remains straight for a long time.
