The invention belongs to the field of refrigeration equipment, and particularly discloses a vehicle circulating water cooling tower. The vehicle circulating water cooling tower includes a water storage pool and supports, the water storage pool is internally provided with division plates, the top ends of the division plates are provided with a guide plate in a hinged mode, and the inner wall of thewater storage pool is provided with electromagnets; the inner wall of the water storage pool is further slidably connected with floating balls, the guide plate is slidably connected with a clump weight, and a water storage unit includes a water outlet and a mud outlet; the water storage unit further includes a spring which is fixedly connected at the bottom of the water storage pool, the upper end of the spring is fixedly provided with a vibrating plate, and the lower end of the vibrating plate is connected with a rack; a first rotating shaft is provided with a gear which is meshed with the rack, the first rotating shaft is further provided with a first bevel gear, and a second rotating shaft is provided with a second bevel gear which is meshed with the first bevel gear; and the second rotating shaft extends in the bottom of the water storage pool in a penetrating mode, and the portion, extending in the water storage pool, of the second rotating shaft is connected with a plurality ofscraping plates in the circumferential direction. According to the technical scheme, the problem that a cooling water liquid circulating pipeline needs to be closed when sludge in a cooling tower is cleaned, thereby generating economic losses is solved.

The invention discloses a rail vehicle roof drainage protection structure, which includes a protective cover and several mounting parts. A water leakage hole is opened on the part, the mounting part is installed on the roof, and the connecting part extends downwards and is connected with the mounting part. The invention further discloses a rail vehicle roof drainage box, which includes a drainage box body and a drain pipe arranged under the drainage box body, and also includes the above-mentioned rail vehicle roof drainage protection structure, the protection part is located in the drainage box Above the body, the connecting part is located outside the drainage box. The invention has the advantages of being able to prevent sundries from falling into the drainage box, and avoiding obstruction of sundries to cause poor drainage, and the like.

The invention relates to building materials, in particular to a water permeable paving plate and a construction method thereof, wherein a base plate layer and a water permeable layer are provided and the water permeable layer is fixed on the base plate layer. The water permeable paving plate is characterized in that more than two massive paving bodies are arranged in the water permeable layer, the massive paving bodies are fixed on the base plate layer and mutually separated to form a water permeable ditch loop, a water filter is arranged in the water permeable ditch loop and is connected with the base plate layer, and a water guiding hole is arranged on a position on the base plate layer corresponding to the water permeable ditch loop. Compared with the prior art, the invention has the beneficial effects of effectively avoiding the impeded drainage caused by the blocking of the water guiding hole, effectively restraining the occurrence of urban heat island, reducing the labor intensity of staff when paving and achieving the obvious advantages of reasonable structure, convenience for paving, energy saving, environmental protection, good drainage effect and the like.

The invention discloses a waterproof system for a road-tunnel-corrugated-steel primary support structure. The waterproof system comprises a plurality of circumferential drainage pipes, a plurality oftransverse drainage pipes, two longitudinal drainage pipes and circumferential-and-transverse-drainage-pipe inspection openings, wherein the circumferential drainage pipes adopt semicircle drainage pipes; the transverse drainage pipes and the longitudinal drainage pipes adopt HDPE corrugated pipes; the longitudinal drainage pipes are wrapped with a layer of geotechnical cloth; the transverse drainage pipes are connected with a tunnel drainage ditch; the circumferential drainage pipes, the transverse drainage pipes and the longitudinal drainage pipes are communicated with three-way pipes. The waterproof system for the road-tunnel-corrugated-steel primary support structure is reasonable in design and good in drainage effect, and damage of water to tunnel construction and operation can be effectively reduced.

The invention discloses a novel liner plate structure used for a large autogenous mill. The novel liner plate structure comprises a feeding end liner plate, a cylinder liner plate, a discharging end liner plate and a filling ring. The feeding end liner plate comprises a feeding end inner ring liner plate body, a feeding end middle ring liner plate body and a feeding end outer ring liner plate body, all of which are sequentially connected. The cylinder liner plate comprises a feeding end cylinder liner plate body, a middle section cylinder liner plate body and a discharging end cylinder liner plate body. The discharging end liner plate comprises a grid plate, an insensate stone window, an external ore pulp elevator, a discharging end middle liner plate body, a middle ore pulp elevator, an inner ring ore pulp elevator, a material discharging device and the like. A flat-head bolt hole is formed in the material discharging device, and an anti-loosening structure is further arranged at the position, corresponding to the flat-head bolt hole, on the material discharging device. The anti-loosening structure comprises a flat-head bolt, an anti-loosening steel bowl, a large gasket, a lock nut, an anti-loosening bolt, an anti-loosening nut and the like. The problems that during running of the mill, ore pulp circular flow scours an end cover, the filling ring falls, the service life of the cylinder liner plate bodies is not equal, discharging cannot be conducted in time through a discharging opening, the flat-head bolt loosens, and insensate stone is not discharged smoothly can be effectively solved.
