The utility model relates to flowmeter device technical field discloses a kind of swirl flowmeters, including measuring tube, the both ends of measuring tube are fixedly connected with flange, the outside of measuring tube is provided with steady flow component, the inside fixedly connected with racemizer in the one end of measuring tube far from steady flow component, the inside of measuring tube is provided with fairing, the inside of fairing is provided with bevel gear one, the outside of bevel gear one is all engaged with bevel gear two in four corners, the outside fixedly connected with connecting shaft of bevel gear two. In the utility model, by the cooperation of knob, connecting shaft, bevel gear two and bevel gear one, when measuring low flow gas, the flow condition of gas in pipeline can be adjusted by adjusting the force area of fan blade, to ensure the measurement accuracy of flowmeter, and the quick method of knob adjustment makes the device can be quickly adjusted when measuring different gas, improves the measurement accuracy.

The utility model discloses a verticality detection ruler for hydraulic engineering supervision, which comprises a guiding rule main body and a heightening assembly, the guiding rule main body is used for measuring the verticality of a wall surface, the heightening assembly is used for heightening the guiding rule main body, the heightening assembly comprises a sleeve, the top of the sleeve is provided with a connecting part used for connecting the two ends of the guiding rule main body, and the top of the sleeve is provided with a fixing part. A movable part for heightening is inserted and connected in an inner cavity at one end of the sleeve, and a rotating part for pushing the movable part to move is arranged in an inner cavity at the other end of the sleeve; according to the utility model, the heightening assembly is arranged at the end part of the guiding rule main body, the rotating part in the heightening assembly is used for driving the movable part in the sleeve to move, and the guiding rule main body and the wall to be measured are separated by the moving movable part, so that a user can adjust and move the movable part according to the height of a screeding protruding point of the wall to be measured; the guiding rule body is raised, and the situation that the protruding screeding protruding points of the to-be-measured wall face affect measurement of the guiding rule body on the perpendicularity of the wall is avoided.

The utility model relates to a kind of grain condition measurement and control system in-store wiring structure for granary, including granary and the center tube being set in the middle part of granary, the top of center tube is communicated with grain inlet, the bottom of center tube is communicated with grain outlet, the lateral wall of center tube is equipped with multiple over-grain ports of communicating granary;It also includes center measuring tube, peripheral measuring tube and temperature measuring cable;The lateral wall of center tube is fixed with multiple center measuring tubes being spaced apart along its circumferential direction;The lateral wall of center measuring tube is spaced apart along its axial direction and is equipped with several first communication ports of communicating the inside of granary;Peripheral measuring tube is fixed at the bottom of granary, and the lateral wall of peripheral measuring tube is equipped with several second communication ports of communicating the inside of granary;Temperature measuring cable is arranged in center measuring tube and peripheral measuring tube. It can effectively avoid the problem that grain flow directly impacts, rubs or entangles temperature measuring cable during grain discharging process, and ensures the reliability of temperature measuring wiring.
