The invention relates to a box-type three-dimensional garage and a vehicle picking-up and parking method. The box-type three-dimensional garage has a simple structure and is low in manufacturing cost, can be assembled flexibly and randomly and comprises a relatively fixed garage frame, hangers and a plurality of parking units, wherein the hangers are movably installed at the top of the garage frame; a plurality of box-type parking units are stacked in the garage frame; lifting parts for the lifting of the hangers are arranged at the tops of the parking units; and a stacking part is arranged at the bottom of each parking unit and is used for stacking the stacking part on other parking units. According to the box-type three-dimensional garbage and the vehicle picking-up and parking method, the operation is simple and reliable, the problems of insufficient parking places can be solved effectively and the garage frame, a plurality of parking units and the hangers are arranged; a plurality of parking units for the vehicles to drive in or drive out are arranged for picking up and parking the vehicles; and the hangers are arranged at the top of the garage frame and are used for lifting or stacking the parking units.

The invention relates to an apparatus for using a hollow floater to assist in slope drainage and solves the problem that in a dry season with less rainfall, underground water level drops, a slope has no water to be discharged via siphoning, a siphoning system may stop operating, air dissolved in air may be separated out gradually in bubble form, the air accumulates constantly in a siphon, the vacuum degree of the siphon decreases, and it is hard to restart siphoning and even siphoning disappears. The apparatus comprises a hollow floater, anchor cables, an air chamber, a siphon, an exhaust pipe, an air supplement pipe, and a one-way valve; the hollow floater is arranged on the water level in the front of the slope, the bottom of the hollow floater is connected to a foundation through the anchor cables, the air chamber is formed in the hollow floater, one end of the siphon is extended below the underground water level of the slope, the other end of the siphon is passed through the air chamber below sea water level, one end of the exhaust pipe is extended below the underground water level at the rear edge of the slope, the other end of the exhaust pipe is connected to the air chamber, and the air supplement pipe is arranged at the upper end of the air chamber.

The invention relates to the production technology of flexible graphite paper, in particular to a flexible graphite paper calendering device. The flexible graphite paper calendering device is composed of a plurality of sequentially-arranged calenders 2. Each calender is composed of a rack 3, a driving compression roller 4, a driven compression roller 5, a compression roller transmission mechanism and an adjusting mechanism for adjusting a calendering gap formed between the two compression rollers, wherein the adjusting mechanism comprises bearing boxes arranged inside the two sides of the rack, and further comprises a wedge-shaped sliding block and an electric control device of the calendering gap adjusting mechanism, the bearing boxes are in threaded connection with a screw rod of a first worm and gear mechanism, the wedge-shaped sliding block is in sliding fit with the inclined lower bottom edges of the bearing boxes and provided with the inclined upper surface, and the wedge-shaped sliding block is in threaded connection with a screw rod of a second worm and gear mechanism installed on one side of the rack. The flexible graphite paper calendering device has the advantages that independent transmission mechanisms of the calenders are arranged, the device is compact, the using effect is good, and maintenance and disassembly are convenient; the calenders with the same size and diameter are arranged at intervals, loosening and tensioning pressure is applied to graphite paper, and calendering and extending are facilitated; intelligent closed-loop control is adopted, precision of graphite paper calendering thickness is controlled to be high, and control is flexible and reliable.

The skid-mounted equipment for treating mine sewage disclosed by the present invention comprises a first lift pump, a first-level treatment unit, a second lift pump, a second-level treatment unit, a third lift pump, a third-level treatment unit, The fourth lifting pump, the fourth-stage processing unit, the first lifting pump to the fourth lifting pump are all connected to the first water turbine, and also include the first filter, and the water outlets of all the first water turbines are connected to the first filter, and the four-stage The water outlets of the processing unit and the first filter are connected with the fifth lift pump, and the fifth lift pump is connected with the second water turbine, and the water inlet of each first water turbine and the second water turbine is connected with a bottom water pipeline. The installed equipment has no power supply, and the treated water is directly used in the production process of the mining face; the mine sewage treatment method of the present invention realizes the power without power supply in the entire driving process, meets the safety requirements for sewage treatment in coal mines, and can be widely used.

The invention relates to a multifunctional ultrasonic scalpel for tumor treatment. The ultrasonic scalpel comprises a first handle and a second handle, wherein the first handle and the second handle are fixed in a detachable fixed manner through a fixing mechanism, and are arranged in a scissor-shaped structure; blades are arranged at front ends of the first and second handles, and rings are arranged at tail ends of the first and second handles; the fixing mechanism comprises a fixed base, a rotating shaft and a switching block; a first rotary cavity is formed in the fixed base; the bottom of the cylinder-structure rotating shaft is extruded outward to form a clamping part; the clamping part is arranged in the first rotary cavity, so that the rotating shaft can be fixed on the fixed base in a rotating manner; and the switching block is fixed at the top of the rotating shaft. The multifunctional ultrasonic scalpel combines functions of blade and scissor ultrasonic scalpels into a whole, is convenient for surgical operation, has good stability and good safety, and can be used for reducing surgical risks.
