The invention discloses a vibration isolation support of a marine precision measuring device. The vibration isolation support of the marine precision measuring device comprises a tray, a T-shaped support, an auxiliary support and three sets of supporting legs, the tray is rectangular; the T-shaped support comprises a transverse support and a longitudinal support which are connected with the bottomface of the tray, the transverse support is arranged along one side of the tray, transverse notches are formed in the two ends of the transverse support, the longitudinal support is arranged along acenter line of one side of the tray, and the other end extends out of the tray and is provided with longitudinal notches; the auxiliary support comprises a transverse auxiliary support and a longitudinal auxiliary support which are connected with the bottom surface of the tray and are correspondingly parallel to the transverse support and the longitudinal support; and the three sets of supportinglegs are installed at the two ends of the transverse support and the other end of the longitudinal support correspondingly, each supporting leg comprises a balancing weight, a rubber shock absorber and a U-shaped bottom foot, and the postures of the U-shaped bottom feet are adjustable. According to the vibration isolation support, the vibration influence is avoided, the erection positioning stability of a complex area is improved, the influence of vibration factors in a ship measurement environment on the precision measurement device is reduced or eliminated, and the precision and reliabilityof the precision measurement device in the environment are ensured.

The invention relates to an energy-saving LED display screen with a curved-surface air deflector and a using method thereof. The LED display screen comprises an LED display screen body composed of unit plates and a mounting frame for mounting the unit plates. The lower end surface of the mounting frame is fixedly connected with a supporting structure; an expansion driving device is installed abovethe mounting frame; a heat dissipation array is installed behind the mounting frame; a variable-direction air supply device connected with the expansion driving device is installed behind the lower side of the mounting frame, and the variable-direction air supply device is used for providing an air flow for cooling for the heat dissipation array. According to the expansion driving device, the principle of thermal expansion and cold contraction of gas is utilized; when gas expands, the pressure of the gas in the closed tank is increased, the synergistic ball is pushed to move outwards, then atransverse push rod, a vertical push rod, a swing plate and a blending strip are made to act in sequence, so that power driving of the whole equipment is completed; and on the basis of the gas expansion driving principle, the energy is saved, and use of driving equipment is reduced.

The invention discloses a four-wheel independent driving wheel carrier posture-adjustable vehicle comprehensive driving system. The posture-adjustable vehicle comprehensive driving system comprises four wheel carriers, a control unit,four wheel carrier driving mechanisms, four groups of wheel units and four groups of walking driving units; the control unit comprises a vehicle control unit, and a wheel carrier comprehensive controller and a walking electric drive controller which are connected with the vehicle control unit; the four wheel carrier driving mechanisms are connected with the wheel carrier comprehensive controller, and each wheel carrier driving mechanism is connected with the corresponding wheel carrier to control the pose of the corresponding wheel carrier; each group of wheel unit comprises at least two wheels, all the wheels are arranged on the same side of the corresponding wheel carriers, and the pose of each wheel is controlled by the corresponding wheel carrier; and the four groups of walking driving units are connected with the walking electric driving controller, each group of walking driving unit is connected with the corresponding wheel unit, and the running state of each wheel in the corresponding wheel unit is controlled to be a walking state, a steering state or a stopping state. According to the invention, posture adjustability and power output integration can be realized, so that the operation requirements of all ground and high trafficability can be met.

The invention discloses a GPS receptor used for water body suspension mapping and is used for solving a problem of GPS receiver mounting inconvenience. The GPS receptor includes a controllable self setting body used for mounting the GPS receiver and adopting a waterproof sealing measure and an engine driven body provided with a built-in power system and adopting a waterproof sealing measure. The controllable self setting body and the engine driven body are connected to each other through nylon ropes and cables. The engine driven body has self drive capability and can drive the self setting body to move and pull the self setting body to predetermined locations. Besides, the engine driven body supplies electric power for the controllable self setting body through the cables between the engine driven body and the controllable self setting body. The controllable self setting body includes a support part, a floating body part and a cargo cabin. The GPS receiver is mounted in the cargo cabin. According to the invention, the GPS receptor holds the GPS receiver and floats on the water face and can also go down into water in a submersible manner. Besides, the GPS receptor has a self driving performance, so that convenience is made for geographical mapping and locating.
