This invention belongs to the field of stress-strain testing technology, specifically relating to a welded strain gauge for nuclear power plant testing. Both the strain gauge and the terminals are mounted on a metal base. The strain gauge consists of a main strain gauge and a compensating strain gauge. The strain gauge and the terminals are connected by wires. Measuring wires are also connected to the terminals. Measuring wire one has a male connector, and measuring wire two has a female connector. Measuring wire one and measuring wire two are connected via the male and female connectors. Measuring wire two is connected to a compensating bridge box. The compensating bridge box contains two precision resistors, forming a Wheatstone bridge with the main strain gauge and the compensating strain gauge on the metal base. This invention is used for stress-strain measurement on the surface of pressure vessels such as nuclear power pressure pipelines.

The utility model relates to the technical field of smart home equipment, more specifically to a compact intelligent curtain motor, including shell frame and Z shape bottom shell, shell frame is used for with curtain rail assembly, and Z shape bottom shell is located shell frame bottom and is formed with shell frame jointly closed cavity, the lower left corner of shell frame is equipped with square corner, is used for with curtain rail plug -in assembly cooperation realizes horizontal positioning, including shell frame and Z shape bottom shell, shell frame is used for with curtain rail assembly, and Z shape bottom shell is located shell frame bottom and is formed with shell frame jointly closed cavity, the lower left corner of shell frame is equipped with square corner, is used for with curtain rail plug -in assembly cooperation realizes horizontal positioning etc. The utility model passes through the three -dimensional nesting design of Z shape bottom shell and shell frame, and the motor, the speed reducer, the clutch and the power module are arranged vertically in layers in the very small space, solve the installation problem of traditional curtain motor in the narrow rail space, reach the effect of miniaturization, high reliability and easy deployment.

A water pipe connector that rotates in both horizontal and oblique directions includes a horizontally arranged connecting pipe and an obliquely arranged bend connector. One end of the bend connector is coaxially connected to the connecting pipe via a spherical rotary joint, and the bend connector rotates around the axis of the connecting pipe. The other end of the bend connector is inclined relative to the axis of the connecting pipe and has a rotatable nut. The spherical rotary joint includes a first hemispherical shell and a second hemispherical shell, and a rotary connector is provided between the first hemispherical shell and the second hemispherical shell. The rotary connector includes a radially movable joint assembly threaded to the connecting pipe and a retaining ring assembly that cooperates with the radial rotation of the bend connector. This invention achieves the rotational performance of being inclined relative to the axis of the rotary joint by rotating the bend connector around the axis of the rotary joint and using a rotary nut, thus achieving the technical purpose of bidirectional rotation in both horizontal and oblique directions and expanding the connection angle adaptability range of the water pipe connector.

This utility model discloses a modular, configurable curtain-type MBR pulse aeration structure, including two end members and at least one aeration member disposed between the two end members. The two end members and the at least one aeration member are detachably connected by a tenon and mortise structure to form an aeration structure body. The aeration structure body has an inner cavity with a lower opening and a surrounding inner circumferential wall. The upper end of the surrounding inner circumferential wall is connected to the top wall of the inner cavity and is shorter than the circumferential wall of the inner cavity, dividing the inner cavity into an air inlet chamber and an aeration chamber. This utility model adopts a modular, configurable design. By combining different numbers of aeration members, the length of the aeration structure can be flexibly adjusted to adapt to curtain-type MBR membrane modules of various sizes, completely solving the installation difficulties caused by the fixed size of existing aerators.

The utility model relates to a kind of round screen self-locking structure, including round screen whole and equipment shell;Round screen whole is composed of COF structure round screen, plastic shell and debugging board.Liquid crystal is wrapped COF structure round screen by plastic shell side wrapping screen, and the recess for sticking firm COF structure round screen is provided in the wire arrangement position and is hollowed out;There is movable arch-like buckle outside, and the side of buckle close to screen has ridge, and the other side is smooth;Far from screen side is equipped with the structure of locking debugging board;Equipment shell hollow size is slightly larger than the actual size of plastic shell (except buckle position);When assembling, positioning is carried out through buckle, buckle is embedded in equipment shell, and equipment shell is clamped on ridge to realize self-locking;The structure solves the problem that COF structure round screen installation has no positioning reference and is easy to install deviation, and debugging board is difficult to install when in the limit of equipment internal space, with the advantages of accurate assembly, strong space adaptability etc.
