An even number of oilless, waterless and noiseless piston type compressor heads (19) are arranged on the upper end face and the lower end face of a head tray in a center symmetry manner, each end face can be provided with two or four or six or eight or multiple heads, center lines of the heads penetrate the center of the tray, and air inlet pipes and air outlet pipes of the heads are connected in series to form a main air inlet pipe and a main air outlet pipe correspondingly. The double-elliptical track grooves and the double T-shaped rolling connection rods are used for replacing a crank connection rod for transmission, the machine model is ingenious in structure conception, combinations complement each other, and reciprocating drive piston type and diaphragm type compressor with the double-elliptical track grooves is scientific, reasonable, high in efficiency, capable of saving energy, eliminating vibration and removing pulse, stable in running, safe and reliable.

The invention discloses a micro-dynamic ash-discharging ball valve belonging to the technical field of valves and aims to provide an ash-discharging ball valve with small opening torque, smooth ash-discharging process, good ash-cleaning effect on the surface of the ball valve and reliable seal. The technical scheme of the invention is as follows: the micro-dynamic ash-discharging ball valve comprises a valve body, a valve rod, a valve seat and a valve cover, and the ball body of the ball valve is a hemisphere; the micro-dynamic ash-discharging ball valve further comprises a hemisphere bracketand a metal bloated bag; the hemisphere bracket is fixedly connected with the valve rod; the bottom surface of the bloated bag is installed on the hemisphere bracket; the bottom surface of the hemisphere is connected with the top surface of the bloated bag to form a closed hollow cavity; the cavity of the bloated bag is communicated with a compressed air pipeline; and a double-sided stainless steel sealing ring is fixed on the valve seat and contacted with the surface of the hemisphere. According to the invention, the structure for fulfilling a seal depending on a constant pressure between the sealing ring and the ball body of the traditional ball valve is changed, and a drive torque in opening and closing processes is greatly reduced; a hard seal with an ash-scraping function has the advantages of excellent resistance to abrasion, temperature resistance and environmental protection adaptability; and multiple effects of labor-saving in transmission, smooth ash-discharging process, natural ash-cleaning effect, reliable seal, and the like are fulfilled.

The invention relates to the field of sewage treatment devices, in particular to a waste water treatment device for urban underground pipelines, comprising a connecting pipe, a well barrel, a driving structure, a sealing structure, an anti-blocking structure, a storage structure, a filtering structure and a drainage hole; the storage structure is designed In the inside of the well barrel, it is convenient to store the film waste filtered by the filter structure through the storage structure. The storage structure and the well barrel can be slidably connected, so that the storage structure can be lifted by lifting equipment when cleaning the film waste, so that the storage structure Sliding with the well barrel, the storage structure slides out of the well barrel, making the garbage cleaning inside the storage structure more convenient and quick; the driving structure is located inside the well barrel, and the driving structure is connected to the storage structure through the drainage hole, and the sewage enters the driving structure , the potential energy of the water flow is converted into the kinetic energy of the driving structure, so that the driving structure drives the sealing structure to prevent blocking, and the filtering structure is driven to salvage the plastic film in the sewage, so that the filtering performance is better, and the pressure on the connecting pipe is reduced at the same time.

The invention relates to the field of solar energy storage battery cleaning equipment, in particular to convenient-to-clean solar energy storage battery cleaning equipment, which comprises a supporting structure, a driving structure, an angle adjusting structure, a cleaning structure, a transmission structure, a storage box and a pressurizing structure. The driving structure is connected to the transmission structure, the transmission structure is connected to the pressurizing structure, and the cleaning structure is communicated with the pressurizing structure; the wind energy can be conveniently converted into kinetic energy through the driving structure; the driving structure drives the transmission structure; the transmission structure drives the pressurizing structure to pressurize rainwater in the storage box; convenient pressurizing by pressurizing structure is facilitated, water flow is sprayed on the cleaning structure for cleaning, and cleaning is further more convenient andquick; wind energy can be conveniently converted into electric energy through the driving structure, meanwhile, an advertising board can be conveniently placed on the driving structure, the advertising board can be conveniently arranged in multiple directions, meanwhile, the driving structure and the supporting structure rotate, then, the driving structure can rotate conveniently, and the displayeffect on the advertising board is better.

The invention relates to the field of pipeline flaw detectors, in particular to an adjustable protective device for pipeline flaw detectors, which includes a handle, a guide structure, a cleaning structure, a position limiting structure, a fixing structure, an ash removal structure and a transmission structure; Adjust the position of the four guide structures through the limit structure, so that the four guide structures can define a circle, so that the four guide structures are all in contact with the pipeline, which is convenient for use in the flaw detection of pipelines with different diameters, thereby greatly improving the flexibility of operation The four guiding structures are symmetrically arranged in the limit structure in pairs, which makes it more convenient and quick to drive the rotation between the limit structure and the pipeline, facilitates flaw detection at different positions of the pipeline, and facilitates the positioning of the guide structure after the flaw detection is completed. Then the flaw detection quality is greatly improved; the ash removal structure is connected to the fixed structure, so that the guide structure drives the transmission structure to compress the ash removal structure when guiding, so that the ash removal structure can clear the ash on the flaw detector on the fixed structure through gas.
