The invention discloses a nursing bed. The nursing bed comprises a bed frame, a bed board, a slide rail, a drive device, a push rod and a connecting rod, wherein the bed board comprises a hip plate and a back plate; a rotating shaft is arranged on the bed frame and positioned between the back plate and the hip plate, and the back plate and the hip plate are hinged on the bed frame through the rotating shaft; the slide rail is arranged under the back plate and fixed relative to the bed frame; the drive device is slidably connected to the slide rail, and is used for driving the push rod to make scalable motion; the tail end of the push rod is connected with the lower side of the back plate; two ends of the connecting rod are respectively connected with the drive device and the hip plate, and the hip plate is driven to rotate under the bed plate. The nursing bed further comprises a first locking device used for locking the sliding position of the drive device and a second locking device used for locking the rotating angle of the back plate. According to the nursing bed, functions of raising the back and switching the hip plate can be achieved by the drive device, and movement of the back plate and the hip plate can be smooth by the two locking devices, so that the functions of raising back, defecating and changing diapers can be achieved. The nursing bed is simple in structure and convenient to operate, and can be used for reducing the cost.

The invention discloses a construction machine for hollow piles with large diameter and the construction method and usage, which comprises a drilling system, a pile pounding system, a drainage system which are integrated into one part. The pile forming method comprises: a high-spray drilling bit is arranged on a steel tube (a protection cylinder) or on the bottom of an inner hole of a pre-made tube pile for hole drilling and mud making; the mud is drained from a water joint or a drainage pipe; the protection cylinder or tube pile is pressed asynchronously or synchronously along with the drilling bit; during pile-sinking process, water mud is sprayed to the outer soil of the hole to solidify the surrounding soil of the pile and fill the gaps between the pile and surrounding soil of the pile; after the drilling bit reaches certain depth, the water mud is again sprayed to solidify surrounding soil of the pile; lifting the drilling bit; putting down reinforcement cage; casting concrete for piling. The invention is a construction method for foundation piles and drilling with large diameter, super long and high load, which especially provides convenient, labor-saving, rapid and economical equipment and method for marine pile driving.

The invention discloses a circulating fluidized bed enhanced ammonia carbon capture device, comprising: a circulating fluidized bed, a crystallization separator, an ammonia water absorber, an ammonia-carbon separator, a desorber, a desorption solution pump, a mixed liquid storage tank, Lean liquid pump and other components. The concentrated ammonia water in the mixed liquid storage tank is connected to the gas-liquid distributor of the circulating fluidized bed through the lean liquid pump. After the flue gas and the ammonia water are fully contacted in the circulating fluidized bed, the rich liquid is separated by the solid-liquid separator and cooled by the cooler. It is connected to the crystal separator; the liquid outlet at the lower part of the crystal separator is connected to the ammonia water absorber, which is used to absorb the liquid ammonia desorbed and separated by the desorber and the carbon ammonia separator to regenerate the ammonia water absorbent; the outlet of the ammonia water absorber is connected to the mixed liquid storage tank , while the liquid outlet of the desorber is also connected to the mixed liquid storage tank. The circulating fluidized bed enhanced ammonia capture device of the present invention utilizes a circulating fluidized bed to strengthen the absorption of carbon dioxide and improve the absorption efficiency.

The invention discloses a quick painting device for a wall surface. The quick painting device for the wall surface includes a base, a cavity body is formed in the base, a horizontal first gear is movably installed on the inner wall of the top end of the cavity body, and horizontal second gears are separately arranged on both sides of the first gear. The top ends of rotating shafts of the second gears are movably connected with the inner wall of the top end of the cavity body, the first gear meshes with the second gears in a matched mode, and a horizontal first chain wheel is fixedly installedat the bottom end of a rotating shaft of the first gear. A horizontal support plate is fixedly installed at the bottom end of the rear portion of the base, a motor is fixedly installed in the middle of the top surface of the support plate, and a horizontal second chain wheel is fixedly installed at the top end of a rotating shaft of the motor. A rotary shaft penetrates through a second through hole, the rotary shaft is perpendicular to a fixed rod to enable to a long strip plate to rotate and move horizontally, so that when a roller is in a vertical state or the roller is in a horizontal stateand faces upwards, painting operation is carry out, and when the roller is in the horizontal state and faces downwards, paint sticking operation is carried out, so that the roller is refilled with paint, and then the painting operation is carried out.

The invention discloses an extension square cabin. The extension square cabin comprises a medium-sized box body. A liftable middle box cover is arranged at the upper end of the medium-sized box body.A rotatable small box body is connected with one side of the medium-sized box body, and can be sleeved with the medium-sized box body. A movable small box cover is arranged on the small box body. A rotatable large box body is connected with the side, opposite to the side provided with the small box body, of the medium-sized box body, and the small box body can be sleeved with the large box body. Amovable large box cover is arranged on the large box body. Because the extension square cabin can be folded or unfolded in a rotary manner, the operating force needed for extension and contraction can be greatly reduced, manual power can be adopted for operation, a complex power device is omitted, the cost can be reduced, less space is occupied, and the reliability of usage is improved.
