A water discharge valve device includes: a water discharge valve unit which has a valve element for opening and closing a discharge port and a control casing for controlling an up-down movement of the valve element; a casing module which includes a peripheral wall extending upwardly from a bottom wall of a water storage tank while surrounding peripheries of the discharge port and the control casing of the water discharge valve unit, to define an upwardly open space therebetween, an opening formed to penetrate through the peripheral wall, and a switching valve attached to the peripheral wall and adapted to open and close the opening; and a communication port formed in a peripheral plane extending from the control casing of the water discharge valve unit to the discharge port, to provide fluid communication between the casing module and the discharge port.

A LED light emitting group (1) apt to produce an outgoing light beam having its own optical axis (8) is equipped with a plurality of LEDs (18), distributed on a plate-shaped body (13) and having a fixed central plane portion (14) orthogonal to the optical axis (8) and a crown (13) of peripheral plane portions (16) tilted with respect to the central plane portion (14) and converging the one towards the other one and towards the central plane portion (14) and the optical axis (8); each one of said plane portions (14, 16) carrying a plurality of said LEDs (18).

The present invention provides a fast volume measurement method based on space-invariant characteristics. The method includes: extracting and matching feature points and three-dimensional reconstruction of the acquired image; adding the actual distance between feature points and the The distance ratio between the relative coordinate system and the real world is used as the scale information; the three-dimensional coordinates of the feature points are used to construct the Delaunay triangular mesh, and the boundary edge detection elements are added to fit the optimal reference plane; according to the idea of ​​discrete integrals, the triangular mesh Projected onto the datum plane, find the volume of the irregular object surrounded by the triangular network. You can use "one camera, one ruler" to complete the measurement of the actual distance between all the feature points of the object, which saves the trouble of field measurement; at the same time, when constructing the Delaunay triangular mesh, a data structure for detecting boundary edges is added, which can effectively The peripheral datum plane of the formed boundary surface is obtained, which is further used for volume calculation.

A vacuum sucker comprises a cover, a compressing seat, a height adjustment piece and a suction wrapper which are connected into a whole, wherein the upper end and the lower end of the compressing seat are connected with a connecting seat and the suction wrapper; the inner side and the outer side of the compressing seat are connected with the height adjustment piece and a guide ring; the guide ring is matched with the height adjustment piece to allow the height adjustment piece to drive the suction wrapper to move upwards; a hanger is mounted on the connecting seat; a center pole on the suction wrapper is connected with the height adjustment piece into a whole; and the cover is connected with the compressing seat into a whole.The parts forming the sucker are concentric independent pieces; the sucker is simple in structure, easy to manufacture and high in precision; the compressing seat serves as a foundation; the parts are buckled and mounted on the compressing seat; stripping and air leakage affecting a use effect and an adsorption force do not happen; the outer side of the compressing seat is sleeved with the guide ring; the guide ring is matched with the height adjustment piece, so that a stress scope of the suction wrapper is moved to a peripheral plane from the middle; a vacuum space and the adsorption force are greatly extended and increased; and the sucker can be absorbed on an absorption surface without falling for a long time.The center pole connected with the hanger is divided into two independent parts, and the hanger is not directly fixed at the middle part of the suction wrapper, so that the sucker is good in use effect, long in service life and more practical, and the adsorption force can be increased by 20%.
