Abstract: A winch includes a coupling A, a coupling B, a rectangular spring, a gear wheel, a gear rack, a friction ring, and a transmission shaft, etc. By increasing the distance between the adjacent internal teeth of the two-stage planet carrier, it ensures that the three-stage sun gear can be smoothly inserted into the two-stage planet carrier even if the elasticity of spring A is reduced, such that the engagement width between the three-stage sun gear and the two-stage planet carrier can reach the normal requirements. With the design of sliding gear ring and spring C, it can greatly reduce the phenomenon of mis-engagement when the external teeth of the three-stage sun gear enter the internal teeth spacing of the two-stage planet carrier, protect the teeth integrity of the three-stage sun gear and the two-stage planet carrier.

Abstract: A method for determining the diffusion radius of in-situ injection and remediation of contaminated soil and groundwater. According to the triangle method, the hole spacing is perpendicular to the groundwater flow direction, the row spacing is along the groundwater flow direction, and the flow diffusion in the groundwater during the effective time of the remediation agent reaction is considered. Under high pressure rotary injection, the remediation agent and a certain proportion of bromide ions are simultaneously injected into the aquifer as a tracer. The diffusion of the agent is determined by observing the phenomenon of slurry-returning and slurry-channeling of adjacent injection points. After the completion of the injection, the groundwater is quickly sampled in fixed depth, the tracer concentration is quickly detected on site, and the concentration of bromide ions in the groundwater is compared with the background value. Comprehensive determination determines the optimal diffusion radius.
