The invention discloses an easy-to-move intelligent camera device. The device comprises a mounting plate, wherein hexagon bolts are arranged at the four corners of the front surface of the mounting plate; a groove is formed on the front surface of the mounting plate; a sliding rod is fixedly connected between the left and the right sides of the inner wall of the groove; the surface of the sliding rod is sleeved by a sliding block; sliding rails are fixedly connected between the top and the bottom of the inner wall of the groove; protective sleeves are arranged on the left and the right sides of the sliding block; and U-shaped supports are fixedly connected to the top and the bottom of the sliding block. The device provided by the invention has the advantages that a motor, a second rotating shaft, a second gear, a first gear, gear blocks and a mounting bar are arranged; the motor works to rotate the second rotating shaft, upon which the second gear rotates so that the first gear can rotate to enable the mounting bar to move horizontally; and therefore, the sliding block can move horizontally, so that the position of a camera body can be conveniently adjusted, and a monitoring range of the camera body can be enlarged to facilitate monitoring.

The invention relates to an upright post formwork. The upright post formwork comprises four steel formwork bodies and a plurality of fasteners, wherein the fasteners hoop outside the four steel formwork bodies and are arranged in the height direction of the steel formwork bodies, and the adjacent steel formwork bodies are connected by connecting columns with square cross sections; clamping tables extending vertically and outwardly are correspondingly arranged on the side walls of the two sides, correspondingly opposite to the adjacent steel formwork bodies, of the connecting columns, clamping grooves for the clamping tables to be clamped are formed in the positions, opposite to the clamping tables, of the side walls of the sides, opposite to the connecting columns, of the steel formwork bodies, and the shapes of the clamping grooves are matched with the shapes of the clamping tables; a plurality of perforations are formed in the positions, opposite to the clamping grooves, of the outer side surfaces of the steel formwork bodies in the height direction of the steel formwork bodies, and inserting holes which are formed opposite to the perforations in a one-to-one mode are formed in the clamping tables; and the steel formwork bodies are provided with plug pins with the number being matched with the number of the perforations, and the plug pins penetrate through the perforations and are inserted into the inserting holes. The upright post formwork has the advantages that the sealability of the joints of the adjacent steel formwork bodies is ensured, and thus the occurrence of the situation of mud leakage between the adjacent steel formwork bodies is avoided.

The invention discloses a bicycle standing device which comprises a frame body. The frame body comprises a clamping mechanism, a lifting mechanism and a tripper mechanism; the lifting mechanism comprises extension springs arranged vertically and spring connectors connected with the clamping mechanism; hook parts are arranged at two ends of the extension springs, and the spring connectors are provided with connecting rods which are connected with the hook parts and stoppers which are arranged at two ends of each connecting rod and used for preventing the hook parts from releasing from the connecting rods; the extension springs are connected with the frame body and the connecting rods respectively through the hook parts, so that the clamping mechanism can drive a bicycle to stand under tension action of the extension springs. Since the bicycle is parked in a standing manner by the bicycle standing device, occupation rate of the ground area can be reduced greatly, and saving of the groundarea in use is facilitated.

The application relates to a foundation pit support device and a foundation pit support method, belonging to the technical field of building foundation pits. It includes support piles arranged continuously and arranged side by side and reinforcements arranged between two adjacent support piles. The reinforcement includes at least one blocking plate. Connected; the blocking plate includes an abutting plate abutting against the side wall of the foundation pit, a waterproof plate arranged parallel to the abutting plate, and a support plate arranged between the abutting plate and the waterproof plate, the support plate The two ends are respectively connected with the abutment board and the waterproof board; the waterproof board is pasted with a film, and the support board is a honeycomb board. After the setting of the supporting piles is completed, a reinforcing piece is set between two adjacent supporting piles, and the sidewall of the foundation pit between the two adjacent supporting piles is covered by the reinforcing piece, so that the soil on the sidewall of the foundation pit in this area It is not easy to slide into the foundation pit.
