The application discloses a kind of pneumatic directional drilling system and drilling method suitable for local water-containing soft coal seam, including directional drill bit, screw drill, conversion nipple, non-magnetic drill tool, multiple special directional drill pipes and air feeder connected in order from back to front;The screw drill includes output shaft end head connected with the directional drill bit and stator end head sleeved on one side of output shaft end head, and output shaft end head can rotate relative to the stator end head, by setting screw drill and conversion nipple, both directional drilling in water-containing soft coal seam can be guaranteed, and strong blowing process can be implemented to discharge drill cuttings and formation water in hole to outside of hole in time, keep drilling operation continuous and smooth, greatly reduce the amount of operation of pulling down drill during construction, and the comprehensive drilling efficiency can be improved by more than 20%, solve the technical problems of poor formation adaptability of prior art, and cannot realize strong blowing and cuttings discharge and rapid switching of directional drilling during directional hole construction process in local water-containing soft coal seam, resulting in low drilling efficiency.

The utility model relates to water body ecological management equipment technical field especially, more particularly to a kind of shipborne lifting rope winding device used in cooperation with flexible water body ecological wave-damping enclosure, including flexible water body ecological wave-damping enclosure, workboat and lifting rope winding mechanism;Lifting rope winding mechanism is installed on the deck of workboat, and lifting rope winding mechanism can be separately detached;Lifting rope is cooperatively provided on flexible water body ecological wave-damping enclosure, and flexible water body ecological wave-damping enclosure is driven connection by lifting rope and lifting rope winding mechanism, for the realization of the storage and release of lifting rope to adjust the underwater deployment state of flexible water body ecological wave-damping enclosure;The utility model provides the accurate adjustment and efficient storage and release support of underwater deployment state for flexible water body ecological wave-damping enclosure, helps to improve the automation level and operation stability of water body ecological management, and is applicable to the quick deployment and adjustment of flexible enclosure system in river, lake, reservoir and other natural or artificial water body.

The utility model relates to the technical field of rail vehicle bogie, and disclose a kind of rail vehicle bogie lateral damper structure, including bogie, lateral rod and the linear bearing of lateral rod upper sleeve, the both ends of lateral rod are slidably connected with mounting block, and the one end of mounting block is equipped with the sliding cavity matched with lateral rod, the outer wall of lateral rod is equipped with the symmetrical first spring, and one end of first spring is fixedly connected with linear bearing, and other end is fixedly connected with mounting block;This kind of rail vehicle bogie lateral damper structure, by first spring, mounting block can be fixed in the inside of installation groove, further by limiting component, mounting block can be fixed in the inside of installation groove, so that the stability of the device operation is higher, after releasing limiting component, simultaneously pulling the mounting block of lateral rod both ends makes it separate from the installation groove on bogie, lateral rod can be disassembled, so that the disassembly of lateral rod is more convenient.

This invention discloses a meteorological observation drone, belonging to the field of drone observation technology. It includes an airframe, an airborne meteorological station, and a cable deployment and retrieval cabin. The cable deployment and retrieval cabin is used to deploy and retrieve the observation cable, which has multiple profile detection nodes spaced along its axial direction. A counterweight is connected to the end of the cable, forming a three-dimensional detection array. This invention suppresses cable swaying through an active guidance and anti-sway mechanism, removes contaminants from the cable surface using a rotary cleaning mechanism, and can coordinate with distributed counterweight beads to generate vibration to enhance the cleaning effect. Its advantages include synchronous, high-precision, and stable detection of atmospheric vertical profiles, effectively overcoming the technical difficulties of inaccurate data, low efficiency, and poor environmental adaptability in traditional suspended detection methods, thus improving the reliability of the equipment and the accuracy of the detection data.

The utility model belongs to robot demonstration technical field, it discloses a track demonstration anti -collision end effector for industrial robot teaching, including mounting panel, elastic rod body axial buffer mechanism and elastic rod body radial buffer mechanism, the through -hole that mounting panel one end set up has, the demonstration pen assembly rod is slidably installed in the through -hole, and the demonstration pen assembly rod is elastic rod body, elastic rod body axial buffer mechanism is covered on the elastic rod body and its upper end surface and the lower end surface of mounting panel abut, the top of elastic rod body radial buffer mechanism all can abut and buffer with the upper end outside wall of elastic rod body, the sidewall of mounting panel still is equipped with siren, is provided with displacement detection inductor on the elastic rod body, the panel surface on mounting panel is equipped with the inclination sensor, and displacement detection inductor and inclination sensor all are with siren electric signal link. This end effector can realize the collision buffer question of axial direction and radial direction simultaneously, and realize the collision alarm function simultaneously.
