A modular adjustable fixing device for an underwater acoustic transducer array includes a main support rod, a central structural component, a transducer fixing ring, and a sliding connector. One end of the main support rod is fixedly connected to the interior of the central structural component through three sets of square holes. The other end extends to form a Y-shaped array frame. The extended end of the main support rod is used to fix the transducer fixing ring, which is fixed to the main support rod by the sliding connector and suspended from the rear side of the central structural component. The sliding connector is slidably fitted onto the main support rod and positioned by fasteners, with its end connected to the transducer fixing ring. The central transducer fixing ring is fixed to the top of the central structural component. This invention allows for flexible adjustment of the baseline length of the underwater acoustic transducer array by adjusting the position of the sliding connector, meeting the acoustic testing requirements of different array models. Furthermore, its modular design facilitates easy disassembly and is suitable for stable fixing of transducer arrays in complex aquatic environments.

The utility model discloses an on-line thickness detection device and system. The device comprises a C-shaped arm beam, a guide roller mechanism, a lead screw transmission mechanism, a first displacement sensor assembly and a second displacement sensor assembly. The guide roller mechanism is used for rolling a to-be-detected pole piece, the first displacement sensor assembly is used for detecting a first distance of the upper surface of the rolled to-be-detected pole piece, and the second displacement sensor assembly is used for detecting a second distance of the lower surface of the rolled to-be-detected pole piece. The screw rod transmission mechanism is used for driving the C-shaped arm beam to move; the two displacement sensors are connected through the C-shaped arm beam, the upper surface distance and the lower surface distance of the to-be-detected pole piece are detected through the two displacement sensors respectively, the thickness of the to-be-detected pole piece is calculated through the distance between the displacement sensors and the upper surface and the distance between the displacement sensors and the lower surface of the to-be-detected pole piece, the structure is simple, and accuracy is high.

The invention provides an anti-clogging rainfall measuring device and a measuring method, and relates to the technical field of meteorological monitoring, the anti-clogging rainfall measuring device comprises a base and a collecting part, the collecting part is arranged on the base, impurities such as fallen leaves doped in rainwater can be separated through a conical filter screen, the impurities such as the fallen leaves can fall above the conical filter screen, and the collecting part is arranged on the base; the lifting part can drive the conical filter screen to rotate, fallen leaves can be effectively prevented from covering the conical filter screen to affect rainwater collection of the collection box, and on the contrary, when a gap exists between the top end of the collection box and the inner top wall of the shell, impurities such as the fallen leaves can be discharged from the collection box through the gap; the adjusting part can drive the shell and the collecting box to move upwards, after the shell and the collecting box move upwards, rainwater in the collecting box can flow into the water storage bottle through the lifting part, the rainfall is calculated by observing weight data of the water storage bottle, the influence of impurities such as fallen leaves on the rainwater collecting and measuring process is effectively avoided, and the rainwater collecting and measuring efficiency is improved. And the accuracy of rainwater measurement is improved.

The utility model discloses a detection device for an anti-slip conveying belt, and relates to the technical field of conveying belt detection. The device comprises a belt conveyor, the front face of the belt conveyor is fixedly connected with a controller, the device further comprises a tension adjusting part, the tension adjusting part is installed on the top of the belt conveyor, and the tension adjusting part is used for adjusting the tension of a conveying belt; and the protection part is mounted at the top of the belt conveyor. By arranging the tension adjusting part, when the speed of the conveying belt is low or the conveying belt stops, an electric push rod can push a push block to move leftwards, the push block can push an inclined block, at the moment, a lifting seat moves upwards, a push roller moves along with the lifting seat, and the push roller pushes the conveying belt upwards, so that the tension of the conveying belt is increased; by means of the mode, continuous friction between the conveying belt and the rotating rollers can be prevented, abrasion of the conveying belt is reduced, and the service life of the conveying belt is prolonged.

The utility model discloses an automatic sampling device for obtaining cigarette products from a drum wheel of a cigarette making machine, and belongs to the technical field of tobacco machinery. Comprising a sampling mechanism which comprises a cigarette taking fork, and the cigarette taking fork takes out cigarettes from a cigarette taking and discharging wheel; the cigarette separating mechanism comprises a cigarette conveying belt, and after the cigarettes are taken out by the cigarette taking fork, the cigarettes fall onto the online detection conveying belt along the conveying channel under the action of the conveying belt; an overturning sheet is arranged on the conveying channel, and a hopper is arranged below the overturning sheet; a sliding channel is arranged at the tail end of the cigarette receiving mechanism and the conveying channel, a supporting hand is arranged at the bottom of the sliding channel, and a conveying belt is arranged in the middle of the supporting hand and conveys cigarettes to the measuring unit. By means of the structure, automatic sampling and manual sampling can be achieved at the same time, and sampling is accurate.
