The utility model relates to the field of sightseeing electric vehicles, in particular to a hub structure of an electric vehicle, which comprises a hub main body, one of main bodies used for supporting the sightseeing electric vehicle to run, and a tungsten carbide metal protective layer adhered to the inside of the hub main body and used for enhancing the firmness of the hub main body. The hub structure is provided with the mounting disc, the spacing ring, the first staggered wheel spokes, the small airflow heat dissipation openings, the second staggered wheel spokes and the large airflow heat dissipation openings, and when the hub structure is used on the sightseeing electric vehicle, the first staggered wheel spokes and the second staggered wheel spokes are attached to the two sides of the mounting disc to support the hub body; due to the fact that the first staggered wheel spokes and the second staggered wheel spokes form staggered supporting, the staggered supporting can enhance the supporting stability and the bearing capacity in the hub body to guarantee the structural safety, and then the stability is enhanced through cooperation with the tungsten carbide metal protection layer attached to the interior of the hub body, the hub structure has good bearing capacity.

The utility model discloses a novel ozone generator and belongs to the field of ozone generators. A novel ozone generator comprises a shell and an ozone discharge tube fixedly installed in the shell, the shell is fixedly communicated with an air outlet pipe, the novel ozone generator further comprises a fan installed on the shell, the air inlet end of the fan faces an inner cavity of the shell, and an adjusting part used for driving the fan to ascend and descend in a reciprocating mode is arranged on the shell; the fan is driven by the adjusting part to vertically move along the filter screen and the conical air guide shell, air can be supplied to the interior of the shell, the ozone generation efficiency can be improved, the temperature of external air can be reduced, and the ozone discharge tube can be blown and cooled, and the angle of the shell can be adjusted by driving the linkage part to rotate through the adjusting part. The ozone is uniformly distributed in the disinfection space, so that the air disinfection quality is improved.

The application discloses a conjugated crosslinking monomer, a solid-phase-free drilling fluid thickening agent, and a preparation method and application thereof. The conjugated crosslinking monomer has a stereoscopic alkyl structure and a conjugated diene structure, and is shown in the following formula. The conjugated crosslinking monomer is prepared by synthesizing an alkenyl compound with an adamantane compound in the presence of a catalyst. The conjugated crosslinking monomer is reacted with an alkenyl amide and an alkenyl sulfonic acid to obtain the solid-phase-free drilling fluid thickening agent. The thickening agent has good temperature resistance and salt resistance, and can improve the suspension and rock carrying performance of a clay-free drilling fluid system in a medium-deep well.

The invention discloses a conjugated cross-linking monomer, a tackifier for solid-free drilling fluid and a preparation method and application of the tackifier, and the conjugated cross-linking monomer has a three-dimensional alkyl structure and a conjugated diene structure and is shown in the following formula. In the presence of a catalyst, an alkenyl compound and an adamantane compound are subjected to a synthetic reaction, and the conjugated crosslinking monomer is prepared. And reacting the conjugated crosslinking monomer with alkenyl amide and alkenyl sulfonic acid to obtain the tackifier for the solid-free drilling fluid. The tackifier is used in a solid-free drilling fluid, is good in temperature resistance and salt tolerance, and can improve the suspension and rock-carrying properties of a clay-free drilling fluid system of a medium-deep well. # imgabs0 #

The utility model discloses a collision extended-range spark catching device, and belongs to the technical field of dust removal devices. Comprising a dust removal machine body, an air inlet and an air outlet are formed in the dust removal machine body, the dust removal machine further comprises a catching cavity base, a fire damper plate and a metal spiral net, the catching cavity base comprises a sealing plate, the sealing plate is fixed to the outer portion of the air inlet through bolts, a square pipe cavity is integrally formed in the inner side of the sealing plate, and the square pipe cavity and the air inlet are movably embedded; the sealing plate is provided with a flange opening right opposite to the square pipe cavity. The fireproof plate is of a frame-shaped structure with the two hollow sides, and the fireproof plate and the inner face of the sealing plate are fixed through bolts. Multiple layers of metal spiral nets are arranged, and the multiple layers of metal spiral nets are mutually pressed; meshes of the adjacent metal spiral nets are arranged in a staggered manner; the space between the fire damper plate and the sealing plate is filled with the metal spiral net, the collision range-extending spark catching device plays a role in filtering, meanwhile, the stroke of sparks is increased, spark catching and filtering are achieved, and the internal energy of the sparks is reduced.
