The present invention concerns an arrangement for in situ mounting of rotor blades to a rotor hub of a wind power plant comprising rotor blades, a rotor hub (40), a disc (1), a means for rotation (30) of the disc (1) around its axis. The disc (1) is in connection with the rotor hub (40) in such a way that when the disc (1) rotates a certain degree of angle around its axis (3) it will cause the rotor hub (40) to rotate the same degree of angle around the axis of the rotor hub. When the means for rotation (30) comes into a desired position, the disc (1) is secured by a securing means (20; 36, 37).

A connecting rod-piston mounting arrangement for a reciprocating compressor of small refrigeration systems, in which one of the parts defined by the piston (10) and the end (22) of the connecting rod (20) adjacent the said piston (10) carries a first spherical seat (11) and a spherical annular seat (12), the other of said parts incorporating a second spherical seat (23) turned to the first spherical seat (11) and a spherical annular surface (24) seated against the spherical annular seat (12), said first and second spherical seats (11, 23) being seated onto respective opposite spherical surface portions (31, 32) of a ball joint element (30) provided between the piston (10) and the connecting rod (20).

The invention belongs to an air controlled distribution valve, in particular to a stepless speed-regulation slow-reduction air-controlled distribution valve. The valve comprises a cylinder cap, a cylinder body, a valve body connected with the cylinder body and a valve plug arranged inside the valve body, wherein an oil inlet P, two oil return ports O and an oil outlet A are formed in the cylinder body; a slow-reduction controlling air port B is formed in the cylinder cap; a lift and drop controlling air port is formed in the cylinder body; oil intake and oil return channels are arranged in the cylinder body, and a check valve is arranged between the oil intake and oil return channels; the tail end of the valve body is provided with a plug; an air-controlled slow-reduction piston, an air piston and a cylinder guide sleeve are arranged sequentially in the cylinder body from the cylinder cap to the valve body; the front end of the valve plug is connected with the air piston; a returning spring is sleeved on the valve plug; the dropping ledge surface of the valve plug is provided with at least two damping grooves along the periphery with equal angles; the oil-return channel is communicated with the cavity of the cylinder body outside the valve plug through a pipeline; a seal ring is arranged between the valve body and the plug cap and between the valve body and the cylinder body respectively. The distribution valve is used for solving the problem that a conventional product does not have the stpeless speed-regulation slow-drop function, and has the advantages of being capable of realizing stepless speed-regulation drop-reduction function, easy in assembly and the like.

The invention discloses an ROV-based underwater equipment retractable device, deployment and recovery method, which are used to realize the docking and locking of the underwater equipment and the operating underwater robot (ROV) body, and complete the underwater equipment by controlling the ROV. deployment and recovery; the device includes ROV-side connecting parts and equipment-side connecting parts, the ROV-side connecting parts are connected to the ROV body, and the equipment-side connecting parts are connected to underwater equipment; when the device deploys underwater equipment, the ROV The terminal connection part and the equipment end connection part complete the docking and locking operation on the deck to form a combination. By deploying the ROV body, the combination is deployed to the installation point on the seabed, and the deployment of the underwater equipment is completed by unlocking the device; When the device recovers the underwater equipment, the connecting part of the ROV end and the connecting part of the equipment end are docked and locked on the seabed to form a combined body. By recovering the ROV body, the combined body is recovered to the deck, and the underwater equipment is completed by unlocking the device. Equipment recycling.

A refrigeration appliance, comprising a box body (1), a door (2) and a hinge assembly (3) connecting the box body (1) and the door (2), the hinge assembly (3) comprising: The mounting part (31) of the box body (1); the hinge part (32), which is connected to the mounting part (31) and has a hinge shaft (320) connected to the door (2); and the adjustment unit, comprising An adjustment piece (30) connected to the hinge piece (32), the adjustment piece (30) is used to adjust the position of the hinge piece (32) relative to the installation piece (31) along the adjustment direction, and the adjustment direction It is the width direction of the door (2) or the front-rear direction of the box body (1). The technical solution can solve the appearance / sealing problem caused by the uneven distance between two doors (2) or between the door (2) and the box body (1).

The invention discloses a connecting mechanism and a mounting method for connecting a closestool cover plate and a closestool base. The connecting mechanism comprises a supporting base and a bolt, a protruding edge is arranged on the top of the bolt, a supporting shaft is arranged on the top surface of the supporting base, a receding hole is concavely formed in the top surface of the supporting base, and a limiting column is arranged on the top surface of the supporting base. The connecting mechanism further comprises a movable piece and an adjusting sleeve, internal threads are arranged on the inner circumferential surface of the adjusting sleeve, external threads are arranged on the outer circumferential surface of the movable piece, the external threads and the internal threads are connected in a screwed mode, a penetrating hole, a receding hole and a locking hole are formed in the movable piece, the supporting shaft penetrates through the penetrating hole, and the limiting column is inserted into the limiting hole. The bolt penetrates through the locking hole and the receding hole to be connected with the closestool base so as to enable the supporting base to rotate in the circumferential direction, next, the adjusting sleeve is rotated to make the movable piece move upward to be pressed against the protruding edge, and thus the supporting base can be stopped from rotating in the circumferential direction. The movable piece is made to be pressed against the bolt by rotating the adjusting sleeve, the pre-tightening function is played, and the mounting operation can be carried out conveniently and fast.
