The invention discloses a shaping reinforcing part of a square column template, and belongs to the field of building templates. The shaping reinforcing part of the square column template comprises clamp plates and wedge blocks. U-shaped clamp grooves are connected to the clamp plates. The clamp plates can be matched and connected end to end through the U-shaped clamp grooves. Strip-shaped throughholes are dug in the top walls of the clamp plates. The wedge blocks are connected in the strip-shaped through holes in an inserted manner. First fixed blocks are connected to the top walls of the clamp plates. Second fixed blocks are connected to the bottom walls of the clamp plates. Threaded holes are dug in the top walls of the first fixed blocks and the top walls of the second fixed blocks. The first fixed blocks are in threaded connection with first connecting rods through the threaded holes, and second connecting rods are in threaded connection to the outer walls of the second fixed blocks. The shaping reinforcing part has the beneficial effects that it can be guaranteed that the multi-layer reinforcing part has the same acting force to the square column template, the square column template is stressed uniformly, and therefore the situation that due to the fact that the square column template is not stressed uniformly, the surface of a poured square column is uneven, and the quality of the poured square column is influenced is avoided.

The invention provides a tidal current energy and vortex-induced vibration energy comprehensive power generation device. The tidal current energy and vortex-induced vibration energy comprehensive power generation device comprises a tidal current energy water turbine and a vortex-induced vibration energy capturing device. A power generator, a power distribution box and a rectifying and voltage-stabilizing device which are sequentially connected with an impeller through wires are arranged in a power generator cabin of the tidal current energy water turbine. The vortex-induced vibration energy capturing device comprises a shell, a vibrator sliding along a guide rail, and a piezoelectric plate, wherein the shell is mounted on the rear side of a single pile foundation, the two end edges of the vibrator are arranged on the top surface and the bottom surface of the shell, and the two ends of the piezoelectric plate are connected with the vibrator and the rear end face of the shell correspondingly; and a conductive copper sheet is arranged at the end, connected with the rear end face of the shell, of the piezoelectric plate and sequentially connected with the rectifying and voltage-stabilizing device and the power distribution box located in the power generator cabin through wires. Water flow enters the shell after encountering the single pile foundation of the water turbine, vortexes falling alternately are generated on the two sides of the pile foundation, and vortex resonance is formed when the vortexes pass through the vibrator; and under the wake flow galloping effect, the vibration amplitude of the vibrator is greater than the vibration amplitude caused by resonance of ordinary vortexes, the vibrator drives the piezoelectric plate to swing left and right, and thus mechanical energy is converted into electric energy.

The invention discloses a bag type filter, which comprises a case, wherein a filter core is arranged in the case; the filter core is fixedly arranged on the inner side wall of the case through two elastic fixing elements; the two elastic fixing elements are in left and right symmetrical arrangement; each elastic fixing element consists of a slide rod, a jacking block, a circular ring, a second soft pad, a threaded section and a buffer ring; the slide rod is arranged inside the filter core; the top end of the slide rod is provided with a jacking block; the circular ring is arranged in the middle part of the upper end of the jacking block; the second soft pad sleeves the slide rod and is arranged between the jacking block and the filter core; the lower part of the slide rod is made into a threaded section; the threaded section is arranged on the inner side wall of the case and is connected through screw threads; the buffer ring sleeves the slide rod and is arranged between the filter core and the inner side wall of the case. The filter core is fixedly installed through the elastic fixing elements; a medium can generate the impact force effect on the filter core; the elastic fixing elements can achieve the buffer effect; the impact effect of the medium is reduced; the filter core is prevented from receiving great impact force; the service life of the filter core is prolonged.

The invention provides an inner-supporting clamp of a constant-velocity universal joint bell housing, which is mainly applied to the machining field of the constant-velocity universal joint bell housing. The inner-supporting clamp comprises a clamp body, wherein a top block is arranged on the side part at the front end of the clamp body; and an ejecting structure for ejecting the top block is arranged on the clamp body. The inner-supporting clamp of the constant-velocity universal joint bell housing can be used for clamping the constant-velocity universal joint bell housing by one step, and simultaneously completing rough-finish turning machining of the outer diameter and the end surface of the bell housing, so that secondary clamping error risks are removed and the time consumption for disassembling the clamped workpiece is reduced. Besides, the inner-supporting clamp of the constant-velocity universal joint bell housing has the advantages of being high in machining product precision, small in labor intensity and high in production efficiency.

The invention relates to a method for improving the service life of turbine blades based on laser double-sided shock technology. Firstly, Nd:YAG pulsed lasers are used to perform equal-energy laser beam splitting; then, using flowing water as a constrained layer, the blades are impacted and strengthened at the same time by using gradient facula overlapping ratios. At the root, the fixture fixes the turbine blade, using high-energy and large-spot pulsed laser with a 90% overlap rate to impact the bottom of the blade root on both sides at the same time; The lap rate of the previous impact minus 10% is used for impacting; until the lap rate is 0, the laser shock strengthening of the blade root is completed. It makes up for the shortcomings of insufficient impact depth of mechanical shot peening, and adopts a gradual lapping rate to impact the root of the blade to make the distribution of the residual stress field smoother; adopts the laser double-sided impact method to avoid deformation and damage of the blade caused by single-sided laser impact. Simultaneous impact makes the front and back of the blade bear the same force.
