Biomimetic quadruped robot provided with head and tail balance adjustment devices

InactiveCN103192898AEasy to observe onlineGood exerciseVehiclesTerrainThree-dimensional space
The invention relates to a biomimetic quadruped robot provided with head and tail balance adjustment devices. The biomimetic quadruped robot comprises a trunk, a head balance adjustment device, a tail balance adjustment device and four robot legs, wherein the four robot legs are distributed under the robot trunk, and the head balance adjustment device and the tail balance adjustment device are located on a trunk front portion cross beam and a trunk back portion cross beam. The biomimetic quadruped robot uses a digital steering engine as a driver, and the steering engine can achieve speed and position control and feed back speed, positions, force moment and other information and facilitates on-line observation of a motion state of the robot. Each leg is provided with three driving freedom degrees and one driven extension freedom degree, three-dimensional space motion can be achieved, and the robot can have strong adaptive capacity to complex environments and obstacle crossing ability. The centre-of-gravity position of the robot can be timely adjusted when the robot with the head and tail balance adjustment devices walks in a static state, and the stability of the robot is improved. When the robot is in a unstable state, namely turns over, and reverse rotation force moment is produced by rapidly rotating the head and the tail to prevent the robot from turning over and being restored to be in a balanced state. The biomimetic quadruped robot provided with the head and tail balance adjustment devices is suitable for the multiple fields of military affairs civil cargo transportation, anti-terrorist devices, filed probing, planetary exploration and the like under complex terrain environments.

Novel medical stone micro-ecological repairing additive and preparation method thereof

InactiveCN101230322APromote carbon nitrogen oxygen cycleRepair micro-ecological environmentBacteriaMicroorganism based processesBacillus licheniformisEutrophication
The invention relates to a preparation and the preparation method for restoring the microecological bacteria on the interface layer of water-sediment. The microecological bacteria preparation uses 0.2-0.4mm of medical stone as carrier, absorbs and fixes the composite microbe optimally combined by bacillus subtilis, bacillus licheniformis, bacillus megatherium, and thin yellow streptomyces. The amount ratio of bacillus subtilis to bacillus licheniformis to bacillus megatherium approximates to one to one to one; the volume ratio of the mixture liquid of the three kinds of bacillus to the thin yellow streptomyces liquid is two to one. The invention has the advantages that spreading the preparation of the invention into the interface layer of functional water body water-sediment in the spring March to April each year can prevent blue algae (aerugo micro-capsule algae is the most) from fulminantly growing in summer June to August. The preparation can improve the quality of water, can prevent eutrophication development, and can promote the carbon, nitrogen, and oxygen circulation on the interface layer of water-sediment. The microecological bacteria preparation has high effective colony amount and strong adaptability; and is effective to restore the microecological environment at the interface layer of water-sediment.

Water quality purifying agent

ActiveCN105217802ASolve the suspension reuse problemSolve the problem of substrate hardeningBiological water/sewage treatmentSodium bicarbonateMicrobial agent
The invention discloses a water quality purifying agent. A formula of the water quality purifying agent comprises the following components in parts by weight: 15 to 55 parts of potassium hydrogen persulfate composite salt, 0 to 5 parts of sulfamic acid, 5 to 20 parts of citric acid, 1 to 12 parts of sodium carbonate, 0 to 10 parts of sodium bicarbonate, 0 to 0.5 part of magnesium carbonate, 0 to 9 parts of sodium hexametaphosphate, 15 to 30 parts of calcium peroxide, 0 to 1 part of sodium dodecyl benzene sulfonate, 0 to 2 parts of lauryl sodium sulfate, 0.05 to 0.1 part of polyethylene glycol, 5 to 15 parts of anhydrous sodium sulphate and 15 to 25 parts of composite microbial agent. In the formula of the water quality purifying agent, a composite potassium hydrogen persulfate product detoxifying technology and a sewage treatment technology beneficial for microorganisms to restore the micro-ecological balance are used for substituting the existing product capable of leading to the secondary pollution, the advantages such as fast onset of action and lasting effect can be realized, and the water quality purifying agent can take effect within half an hour; the water modification, detoxifying, bacteriostat and water purifying effect can last for 7 to 10 days, and the treatment on the water pollution and the restoration of the ecological balance can be realized in 7 days to 1 month.
