An integrated architecture system for dual-indirect heat pump thermal management in pure electric vehicles based on R290. Currently, most pure electric vehicles have low integration levels in their thermal management systems. Typically, the battery pack circuit and air conditioning circuit are connected in parallel through a heat exchanger, while the motor and electronic control cooling circuit is an independent circuit. This results in too many system components, occupying a large amount of engine compartment space, and lacking a standardized and precise processing structure. In this invention, one end of the radiator is connected to the second refrigeration device, and a first valve body is provided between the radiator and the second four-way valve. The other end of the radiator is a double-ended connection end, which is sequentially connected to one end of the second refrigeration device through the fourth inlet / outlet and the second inlet / outlet of the second four-way valve. A third valve body is provided between the double-ended connection end of the radiator and the second four-way valve. The other end of the second refrigeration device is connected to the first inlet / outlet of the second four-way valve. The double-ended connection end of the radiator is sequentially connected to the fourth inlet / outlet of the second four-way valve through a drive motor, an electronic control unit, and a second water pump.

This invention relates to a tuned damper and a monorail for controlling vortex-induced vibration of a monorail main beam. The damper includes a damping box, a mass block assembly, a spring, a guide shaft, a guide assembly, and damping fluid. One end of the spring is connected to the bottom of the damping box cavity, and the other end is connected to the bottom of the mass block assembly. One end of the guide shaft is connected to the bottom of the damping box cavity, and the other end is connected to the top of the damping box cavity, passing through the mass block assembly. The guide assembly is fixedly connected to the mass block assembly and symmetrically arranged on both sides of the guide shaft. The damping fluid is disposed within the damping box cavity. The advantages of this invention are: 1. By limiting lateral displacement through the guide assembly, stability is increased; 2. Adjusting the base allows for adjustment of the gap between the roller and the guide shaft without affecting the vertical vibration of the mass block assembly, thus promoting stable and long-term operation of the device; 3. The mass block assembly optimizes the adjustment efficiency.

The utility model discloses a kind of automatic cleaning devices of waste copper recovery, and the device is constituted by waste copper transport mechanism, archway type spray cleaning mechanism and high-pressure water pump station.Waste copper transport mechanism is driven by driving motor to drive rotating roller, galvanized sprocket and galvanized chain to run, chain is kept stable using galvanized tensioning wheel, and the stable conveying of waste copper material is realized.Archway type spray cleaning mechanism is equipped with vertical plate, top plate and transparent plate, multiple high-pressure spray heads are arranged in linear array inside, and infrared sensor is installed at the front end of vertical plate.When waste copper material is conveyed to cleaning mechanism by transport mechanism, after infrared sensor senses material, high-pressure water pump station starts, and water is pressurized and conveyed to high-pressure spray head, and waste copper material is comprehensively sprayed and cleaned.This device realizes the automation of waste copper recovery and cleaning, effectively improves cleaning efficiency and quality, and reduces manual operation cost.
