The invention is a walking mechanism for adjustable-height self-position shifting track-type pipeline robot, including two sets of mechanisms of transversely swinging legs, symmetrically distributed at the head and tail of the robot body, the tops of the four legs are hinged on the two sides of two sets of mechanisms of transversely swing legs, respectively, the bottom ends of the four legs are all set with a swing-leg adjusting joint, and four track feet are hinged with the four adjusting joints, respectively. The two sets of mechanisms of transversely swinging legs open the four legs, adjust these joints to make the four track feet return to erecting state so as to reduce the height of the walking mechanism. The pipeline with the wall mechanism can enter multiple pipelines, such as high rectangular pipelines, small-bore circular or low flat rectangular pipelines, etc.

The present invention provides technology for electric single-beam crane to move in curved tracks. In the T-shaped joining part of rivers, two nearby water gates are provided with one shared electric single-beam crane, which can move in straight line and curved line. The two water gates and two crane rooms have central line angle of 90 deg, and two sections of crane running track in 90 deg angle have one circular transition section in between. The electric single-beam crane running mechanism consists of main beam, end beams, turnable wheels, single speed driving motor, double speed driving motor, and contact sensing signal controller. The end beams and the turnable wheels are driven on two sides, the outer side is driven with the single speed driving motor, and the inner side is driven with the double speed driving motor. The contact sensing signal controller consists of contact in the inner side end beam and sliding sheet in the circular inner side track.

The invention provides an environment-friendly track and field runway. The environment-friendly track and field runway is prepared from the main raw materials of 58-62% of Pvc paste resin, 35-39% of dioctyl terephthalate, 1-3% of a calcium-zinc stabilizer and 0.5-2% of azodicarbonamide. The invention further provides a preparation method of the environment-friendly track and field runway. Four substances are mainly adopted for matching, the environment-friendly track and field runway has the advantages of being good in damping effect, excellent in rebounding performance, large in adhesive force, high in spike resisting capability, good in slip resistance and wear resistance and the like and can be widely applied to pavement materials for athletic grounds, and the maintenance frequency can be reduced in application of the environment-friendly track and field runway.

The invention relates to the technical field of hose connectors, in particular to a metal hose connector structure which comprises a left connecting pipe and a right connecting pipe, the right connecting pipe is located at the right end of the left connecting pipe, annular connecting grooves are formed in the outer sides of the left connecting pipe and the right connecting pipe, and clamping plates are slidably connected to the upper ends and the lower ends in the annular connecting grooves. Locking rods are in threaded connection with the upper ends and the lower ends of the left connecting pipe and the right connecting pipe and located on the periphery of the annular connecting groove, a plurality of limiting blocks are fixedly connected to the inner side of each clamping plate, and a plurality of anti-skid grooves with the same number as the limiting blocks are formed in the annular connecting groove and located on the inner side of each clamping plate. Due to the fact that the interior of the annular connecting groove is inclined, hoses with various diameters can be conveniently inserted into the annular connecting groove, the application range is guaranteed, the elastic belt and the hoses are squeezed through the limiting blocks, the hoses and the elastic belt are pressed into the anti-skid grooves, the hoses are difficult to separate from the left connecting pipe or the right connecting pipe, and stability after installation is guaranteed.

The invention discloses a digital display touch controller of a full-automatic feeder. An electric loop of the controller is formed by connecting a power switch (1), a safety circuit (2), a clock circuit (3), a relay J1 drive protection circuit (5), a relay J1 contact protection circuit (6), a material throwing indication circuit (7), a relay J2 drive protection circuit (8), a relay J2 contact protection circuit (9), a touch input set circuit (11), a display drive circuit (12), a power indication circuit (13), a rectification and voltage stabilizing circuit (14), a transformer (15), an emergency switch (16) and a binding post (10). A single-chip microcomputer high in interference prevention performance serves as a core control element, input setting is easy, the time precision is high, the control performance is good, using is safe, and the working reliability is high.

The invention relates to an intelligent humidifying brick, which comprises a functional layer, wherein the functional layer is formed by firing sepiolite clay and glass powder as main raw materials, and the mass percent of the glass powder is 5-20 wt%.

The invention belongs to the technical field of sewage treatment, and especially relates to a treatment device for a sewage pool. The device comprises a separating mechanism and an overturning mechanism, and the overweighting design of an overturning bucket is not restricted by the unstable volume of water in the sewage pool to make the overturning bucket pour out enough water for impacting a square bucket at intervals in order to ensure the normal running of the overturning mechanism. The design of a rotating unit makes floating garbage in sewage collected into the square bucket; the design of a friction wheel, a rotating shaft and an arc-shaped friction bar makes the garbage in the square bucket automatically poured into a garbage bin after the square bucket enters the garbage bin; and the design of a semicircular raised head makes the square bucket shake, and wet garbage adhered into the square bucket can easily fall into the garbage bin from the square bucket, so the influences ofthe garbage always existing in the square bucket on the garbage collecting efficiency of the square bucket are reduced as possible. The device has the advantages of realization of the treatment only through regular garbage removal, reduction of the cost and the workload of artificial salvaging of the floating garbage, and increase of the working efficiency.

The invention is a firmware updating method, firstly writing a label in a firmware storage device storing a first firmware, then replacing the first firmware with a second firmware, successively deleting the label after the replacement is finished, then firstly checking if the label exists before executing the second firmware: if the label does not exist, execute the second firmware; otherwise enter in abnormality processing program. Thus, the abnormality processing program immediately stops the execution of the second firmware and reads a third firmware through an interface to replace the second firmware.
