The invention discloses a waterproof and breathable heat dissipation multifunctional bolt. The multifunctional bolt comprises a bolt head. The bolt head comprises a bolt head body and a bolt head outer cap. The bolt head outer cap is arranged on the outer portion of the bolt head body. A waterproof and breathable layer is arranged between the bolt head body and the bolt head outer cap. When the waterproof and breathable heat dissipation multifunctional bolt is used for fixing a deformable object with small thickness, a waterproof convex ring on the upper portion of a nut is inlaid in a waterproof ring groove at the lower end of the bolt head to prevent outside water from getting into the bolt, and the waterproof effect can be effectively achieved. Under the other condition, if the waterproof and breathable heat dissipation multifunctional bolt is used for fixing hard objects with certain thickness, the two objects are fixed between the bolt head and the nut, and a water baffle is pushed out under the action of elastic force of a spring, so that the lower end of the water baffle makes contact with the upper surface of the first clamped object to achieve the waterproof effect. Oblique through holes and vertical vent through holes communicating with the oblique through holes are formed in the bolt head and can achieve the ventilation and heat dissipation effects.

The invention discloses an unmanned aerial vehicle 5G antenna structure with high wind resistance and reliability, which particularly relates to the technical field of unmanned aerial vehicle antennae. The unmanned aerial vehicle 5G antenna structure comprises an antenna body and a frame plate, the antenna body is arranged in the frame plate, heat conduction plates are embedded in the two sides of an inner cavity of the frame plate, and a first sliding groove and a second sliding groove are formed in the surfaces of the inner walls of the two heat conduction plates respectively; the first sliding groove and the second sliding groove extend to the bottom of the frame plate, a sliding block is arranged in the first sliding groove, a rack is arranged in the second sliding groove, a mounting plate is arranged between the rack and the sliding block, and a connector is formed in the mounting plate. The frame plate is arranged on the outer side of the antenna body, the rack is driven to move up and down through meshing of the rack and the gear, so that the antenna body on the mounting plate is driven to move out of the bottom of the frame plate, and the filter bag on the outer side of the antenna body can play a role in protecting the antenna body and also can play roles in ventilation and heat dissipation; therefore, the antenna body is better in wind-resistant effect and higher in use strength.

The invention discloses a controller panel which comprises an annular Hall plate arranged in a first controller housing and a rectangular controller panel arranged in a second controller housing. The annular Hall plate is radially clamped and axially limited at the outer end part of the first circular insulating framework; the first controller housing is fastened with the iron core and the end cover through a plurality of screw rods; the two sides of the top of the first controller housing are each provided with a first protruding column which is provided with a threaded hole and extends vertically, the inner surface of a top plate of the second controller housing is provided with second protruding columns which correspond to the first protruding columns in position, are provided with through holes and extend vertically, and the end faces of the first protruding columns and the end faces of the second protruding columns are each provided with a step embedded with a rectangular controller panel. The two sides of the rectangular controller panel are provided with notches which are limited with the protruding columns in the radial direction. Two screws penetrate through the corresponding through holes to be screwed into the corresponding threaded holes so as to press the rectangular controller panel. The radial area of the controller panel and the motor is reduced, the controller panel is stable and reliable in fastening, and the heat dissipation effect of the controller is good.

The invention discloses a positioning mechanism for a computer, which comprises a bottom plate; a fixed plate is arranged on one side of the upper surface of the bottom plate; one side of the fixed plate is movably connected with two first limiting plates which are oppositely distributed; the bottoms of the two first limiting plates are in sliding connection with the upper surface of the bottom plate; second limiting plates are movably connected to the opposite sides of the two first limiting plates; the second limiting plate is of a telescopic structure; the first limiting plate is fixedly connected with the fixed plate through a first locking bolt. According to the invention, the fixing plate, the first limiting plate and the second limiting plate cooperate with each other; the two firstlimiting plates are arranged on the main plate body, so that the distance between the two first limiting plates is adjusted according to the width of the main plate body; the two first limiting plates make contact with and abut against the two sides of the main plate body; the first limiting plates are fixed through the first locking bolts, and at the moment, the second limiting plate is installed between the two first limiting plates.

The invention discloses a method for preparing landscaping soil by using urban sludge. The method comprises the following steps: firstly adding chaff chaff, bacterial strains and chaff chaff to urban sludge and mixing uniformly to obtain a sludge mixture material; The sludge mixed material is ventilated and fermented in an environment of 45-60°C for 5-7 days to obtain a fermentation product; the fermentation product is mixed to control the moisture content at 50-60%, and a semi-finished product is obtained after 5-7 days; Add 5.5-11% of mineral materials, 1.5-3% of starch, 0.1-0.3% of composite bacteria, 3-7% of fungus chaff, 5-8% of biochar and soil improver, and stir evenly Afterwards, ferment for 5-7 days in an environment of 45-60°C, and control the moisture content of the soil at 25-35%, so as to obtain landscaping soil. The landscaping soil prepared by the invention meets the nutritional requirements of garden plants and reduces the heavy metal content in the landscaping soil.
