The application discloses a ventricular support drainage device, which comprises a drainage tube, a self-expanding support bracket, a delivery tube and a support strip. The self-expanding support bracket is arranged outside the drainage tube, and the support bracket in an expanded state is used for supporting the ventricular wall. A small protrusion is arranged inside the support bracket, and the small protrusion is in close contact with the drainage tube in a compressed state. The delivery tube is sleeved outside the drainage tube and the support bracket, and is used for maintaining the drainage tube and the support bracket in the compressed state. The support strip is arranged inside the drainage tube in the compressed state, and is used for supporting the whole structure during delivery. The support strip is used for delivering the drainage tube and the support bracket compressed in the delivery tube to a drainage position under the support of the support strip, and maintaining the position of the drainage tube unchanged when the delivery tube is withdrawn. The support strip is blocked at the first end of the drainage tube. The arrangement guarantees that the drainage device is effectively delivered, and the support bracket plays a supporting role and the drainage tube plays a drainage role after being delivered.

The utility model relates to the technical field of automatic production equipment, in particular to a charging tray clamping and feeding device. The feeding assembly is used for driving the material receiving tray to take materials from the material tray on the feeding frame and then transfer the materials to the positioning pressing plate for positioning, the positioning open groove in the positioning pressing plate leaks out the materials on the material tray for feeding, automatic material tray conveying and material tray replacing are achieved, and the working efficiency is high; the clamping assembly is used for clamping the material tray so as to position the material tray on the positioning open groove, so that the material tray with a large length-width ratio is effectively prevented from warping or deforming, the material tray is kept flat, and it is guaranteed that the position of the material in the material tray does not change when the mechanical arm grabs the material on the material tray.

The invention belongs to the technical field of spraying lines, and particularly discloses a metal material double-sided paint spraying device which comprises two symmetrically-arranged spraying mechanisms. An angle adjusting rail is arranged on the section, corresponding to the position between the two spraying mechanisms, of the annular conveying rail, and the number of folding sections of the angle adjusting rail is the same as that of plane parts of the cold-rolled folding plates to be sprayed; the sliding column is arranged on the annular conveying track in a sliding mode, the perimeter of the adjusting gear is m, the supplementary angle of the included angle between every two adjacent plane parts is a, and the length of the adjusting rack at the joint of every two adjacent plane parts and the corner of the corresponding folding section on the adjusting track is ma / 360 degrees; the limiting frame is arranged above the annular conveying rail in a reciprocating sliding mode; the limiting frame elastically clamps the top of the sliding column so as to limit autorotation of the sliding column in the non-meshing state of the adjusting gear and the adjusting rack. Under the action of the adjusting rack and the adjusting gear, the originally inclined plane part just rotates to the state perpendicular to the spraying direction of the spraying gun of the spraying mechanism, and vertical spraying is guaranteed.

This invention discloses a method for manufacturing a traveling wave pump rotor, comprising the following steps: machining the outer shell, machining the base plate and the first injection-molded plate, machining the cover plate and the second injection-molded plate, machining the enclosure mechanism, and machining and forming the rotor. The manufacturing method of this invention is simple in its steps, which not only improves the integral machining quality of the traveling wave pump rotor, but also facilitates the formation of an injection-molded layer on the surface of the traveling wave blades, reducing friction and wear of the traveling wave pump rotor during operation, while also reducing noise and extending the service life of the traveling wave pump.

The utility model relates to a multi-channel raw material synchronous feeding tank which comprises a raw material barrel and discharging grooves, partition plates are installed in an inner cavity of the raw material barrel and divide the raw material barrel into a plurality of cavities, enzyme production raw materials outside the raw material barrel can be placed into the cavities, the discharging grooves are formed below the raw material barrel, and the number of the discharging grooves is consistent with that of the cavities. The discharge chute is communicated with the cavity; a batching barrel is arranged at the lower end of the discharging groove and communicates with an inner cavity of the discharging groove, the outer side wall of the batching barrel is sleeved with a quantifying mechanism, a connecting frame is installed on the side wall of the quantifying mechanism, the output end of a first electric control push rod is installed at the upper end of the connecting frame, and the first electric control push rod is installed on an external fixing frame; the first electric control push rod can drive the connecting frame to move up and down. According to the embodiment of the invention, the quality of each raw material can be adjusted, and the ratio of the raw materials can not be changed, so that the condition of fermentation failure is effectively reduced, and the waste of the raw materials and the prolonging of the production period are avoided.

The application discloses a resource scheduling scheme effectiveness verification method and system based on execution information, and belongs to the resource scheduling field. The method comprises the following steps: constructing a priori known time network, using a priori known accidental link and an observation link to represent an action with uncertain duration and an observation process that can obtain execution information in an execution process, obtaining time constraints that need to be met at all controlled time points by applying propagation constraints, realizing the use of execution information to deal with time uncertainty, verifying whether the resource scheduling scheme meets the dynamic controllable condition when facing time uncertainty by using a dynamic controllability detection algorithm, and then judging whether the resource scheduling scheme can be successfully executed after the execution information obtained in the execution process is used to reduce uncertainty. The method has considered the execution information that can be obtained in the execution process in the verification process, and improves the accuracy and efficiency of the verification.
