The invention discloses a server cabinet cable storage rack which solves the problem that existing server cabinet cables are difficult to card and mark. The server cabinet cable storage rack comprises a rectangular back plate (1), a rotating shaft seat (4) and a rotating shaft (5) are arranged at the left side edge of the back plate, the rotating shaft (5) is fixedly connected with a rear side edge of a left side face (6) of a U-shaped cover (3), a left clamping groove (15) in a vertical direction is arranged on the inner side of each of three side faces of the U-shaped cover (3), a clamping joint (18) is arranged on each of four vertical angles of a diamond cable clamping plate (13), a cable clamping groove (19) is arranged at each of four edges of each diamond cable clamping plate (13), and the diamond cable clamping plates (13) are clamped together with the left clamping groove (15), a front clamping groove (16) and a right clamping groove (17) respectively through the clamping joints on the three vertical angles. The server cabinet cable storage rack is simple in structure, convenient to mount, and applicable to mounting and use of and various cabinets.

The invention relates to a basin mounting tool. The basin mounting tool is characterized by comprising a supporting piece and a connecting rod; the supporting piece is provided with a middle part parallel to the connecting rod, an upper end bent part and a lower end bent part, the upper end bent part and the lower end bent part are perpendicular to the middle part and are provided with through holes allowing the connecting rod to penetrate through, and the two opposite side edges of the upper end bent part are provided with upwards-bent baffles; and the baffles and the upper end bent parts form a limiting groove. Compared with the prior art, basin fasteners can be conveniently conveyed into a narrow space by means of the basin mounting tool provided by the invention, and can also be limited in the circumferential direction and the axial direction so as not to rotate in the locking process, the mounting efficiency is greatly improved, and the mounting difficulty is reduced.

The invention discloses a sector electric folding door. A door column of the sector electric folding door is provided with a U-shaped door plate groove; a plurality of door plates are sequentially arranged in a front-back stacked mode; a door plate mounting shaft is fixedly mounted at the lower end of the door plate groove; all the door plates are mounted on the door plate mounting shaft in a pivoted mode, and linkage pieces are mounted on the back faces of all the door plates; the linkage pieces between every two adjacent door plates are connected in a sliding fit mode; door plate connecting pieces are mounted on the inner wall of the top of the door plate groove; the linkage pieces on the back faces of all the door plates and the door plate connecting pieces are all located on the same arc section with the door plate mounting shaft as the circle center; the linkage pieces are in sliding fit along the track of the arc section; the door plates comprise the door plate at the rearmost end, the door plate in the middle and the door plate at the foremost end; a driven gear is mounted on the plate wall of the door plate at the rearmost end in a fastened mode and is coaxial with the door plate mounting shaft; a gear driving device for driving the driven gear to rotate is mounted on the door column; and the door plates of the sector electric folding door can be opened or closed in a sector folding mode, the door plates are spliced into a square door body when unfolded, and the door plates are hidden in the door plate groove of the door column when folded.

The invention discloses an energy-saving self-excitation type retarding device. The energy-saving self-excitation type retarding device comprises a self-excitation type retarder, a vehicle transmission shaft and a generator shaft. The retarder mainly comprises a retarder rotor disc, a retarder iron core and a retarder coil, and the self-excitation type retarder and a connector of the generator shaft are installed on the vehicle transmission shaft. When a vehicle brakes, the retarder iron core is driven to rotate by energy of motion of the running vehicle, so that an eddy current braking torque is generated on the retarder rotor disc. Besides, the energy of motion of the running vehicle is further used for driving the generator shaft to rotate, so that the energy of motion is transformed to electric energy and is stored in a storage battery through the work of a generator. According to the energy-saving self-excitation type retarding device, combined actions of retardance mechanisms of two types are adopted, so that the braking effect of the vehicle can be effectively and reliably guaranteed, and the aims of energy storage and energy saving are achieved. The energy-saving self-excitation type retarding device is reasonable in distribution, simple in structure, convenient to maintain and suitable to be installed and used in a motor bus and an electric car.

The invention relates to a double-wall pipeline for the connection of a fuel-gas valve set and an engine on an LNG ship, which comprises an internal pipe and an external pipe, wherein the internal pipe and the external pipe are coaxially sleeved and supported by a plurality of detachable clips, one end of the external pipe is fixed on the side wall of a fuel-gas valve set chamber provided with the fuel-gas valve set, one end of the internal pipe is communicated with the fuel-gas valve set by a transitional connection pipe, the other end of the internal pipe is communicated with the air inlet of a double fuel-gas engine by an internal corrugated pipe, the aperture of the internal pipe is the same as that of the air inlet of the engine, and a circular chamber is arranged between the internal pipe and the external pipe and communicated with the fuel-gas valve chamber to together realize air change. The double-wall pipe of the invention has simple and practical structure, uses common material of easy production and low cost, and can be rapidly and conveniently assembled and disassemble by using common tools when being applied on the LNG ship.
