The invention relates to the technical field of hydro meteorology observation, and particularly discloses a hydro meteorology observation instrument and a putting device thereof.The hydro meteorology observation instrument comprises an upper shell and a top cover for pressing and covering the top end of the upper shell, a detection element and a fixing plate are arranged in the upper shell, and the fixing plate is installed above the top cover in a sliding mode; a photovoltaic panel is attached to the surface of the fixing plate; the bottom plate is fixedly connected to the bottom end of the upper shell in a sealed mode, a storage battery is arranged on the surface of the bottom plate, and a mounting frame is arranged above the storage battery; and the lower shell is connected to the lower portion of the upper shell, and a counter weight mechanism which stretches and retracts downwards is arranged in the lower shell. According to the hydro meteorology observation instrument and the throwing device thereof, displacement caused by stormy waves can be effectively reduced, stability is enhanced based on gravity center adjustment and lowering, birds can be automatically repelled, stable monitoring and use of the buoy are guaranteed, the throwing device is conveniently installed and used along with a ship, and long-distance buoy throwing and use in shallow water are facilitated.

The utility model provides a rotary throwing type anti-turning nest throwing boat, which relates to the technical field of fishing equipment, and comprises a boat body, a bait casting box arranged at the tail part of the boat body and a propeller, the middle part of the boat body is provided with a mounting hole vertically communicated with the inner space of the boat body, a rotary throwing mechanism is arranged in the mounting hole, and the rotary throwing mechanism comprises a throwing hopper and a rotary motor, the throwing hopper is of a circular truncated cone-shaped structure with a wide upper part and a narrow lower part; the wide opening end of the throwing hopper is upwards arranged in the mounting hole; the rotating motor is arranged in the ship body, and the bottom of the throwing hopper is connected with an output shaft of the rotating motor through a transmission assembly. According to the bait casting machine, the mode of combining material rotary throwing and dumping is adopted for casting, the mechanism layout is optimized, the stability and the wind resistance of a ship body are effectively improved, the bait casting amount can be controlled, the contradiction between the function and the stability of an existing product is solved, and the casting effect and the use safety are further optimized.

The utility model provides a kind of to make nest lure fisher, it is related to fishing auxiliary appliance technical field, solve the technical problem of inconvenient discharge amount adjustment of existing technology in the nest lure fisher.This nest lure fisher includes pusher, adjusting slide and adjusting assembly, discharge passage is provided on pusher, adjusting slide is slidably arranged on pusher, adjusting assembly is connected with adjusting slide, and the operating end of adjusting assembly is located outside the nest lure fisher, adjusting assembly is used to drive adjusting slide linear displacement, to change the volume of discharge passage.The utility model realizes stepless regulation by the linear movement adjustment of adjusting assembly, and can be operated without pouring nest material, so that discharge amount adjustment is simple.

The invention belongs to the technical field of tunnel construction, and particularly relates to a dust falling device for tunnel construction, which comprises a water tank, a water guide pipe is rotatably mounted on the inner wall of the water tank, a dust falling assembly is arranged on the outer side of the water guide pipe, and a mounting assembly for mounting the dust falling assembly is arranged above the water tank. An angle adjusting assembly used for adjusting the angle of the mounting assembly is arranged on the inner side of the mounting assembly, and a driving assembly is arranged on the inner side of the water tank. Through rotation of the dust falling assembly, the 360-degree spraying effect can be achieved, and no-dead-corner spraying is conducted on the surrounding environment, so that the dust falling coverage range is effectively widened, the dust catching efficiency is improved, and the problem that the dust concentration of a local area is too high due to angle limitation of traditional fixed dust falling equipment is solved; the angle adjusting assembly can adjust the angle of the dust falling assembly in a reciprocating mode, a three-dimensional dust falling space is formed by adjusting the angle of the dust falling assembly, and the dust falling effect of the device is improved.
