The invention discloses a floating table type wave power generation device achieving netting large-scale application. The floating table type wave power generation device is characterized in that based on combination of floating platforms capable of suspending in water when being in the stable state and the moving state, the difference between different influences of different powers of flowing and floating of waves to the floating platforms is utilized, interaction is generated, the lever principle is adopted, the motion is converted into mechanical vibration, and a driving mechanism acts togenerate power. According to the power generation device, two forms are taken as labor division of the lowest starting point, based on this, combination of lowest quadrangle netting is achieved, meanwhile, the power generation device is provided with multiple automatic adjusting mechanisms, comprehensive utilization of wave energy is emphasized, all-weather all-ocean natural environmental suitability is emphasized, particularly, the group large-scale application is emphasized, and the brand-new ocean wave energy development scheme is achieved.

The invention discloses an oxygen therapy device for agriculture, in particular to an automatic oxygen therapy crop waterlogging reduction device based on farmland water level. The automatic oxygen therapy crop waterlogging reduction device based on the farmland water level comprises an oxygen bottle, a water level monitoring device, a first automatic controlling valve and an underground pipeline device. The water level monitoring device is arranged underground, the first automatic controlling valve is arranged at the outlet end of the underground pipeline device, the water level monitoring device is connected with the automatic controlling valve, and the oxygen bottle is connected with the underground pipeline device. The water level sensing portion of the water level monitoring device is arranged near the upper portion of the underground critical depth of water, when a preset oxygen supplying condition is met, redundant water inside the pipeline is discharged, oxygen is transmitted to the root zones of crops automatically, the whole discharge pipeline is aerated, and the oxygen is dispersed to around root zones of the crops through holes on the discharge pipe. The automatic oxygen therapy crop waterlogging reduction device is capable of supplementing oxygen at the root zones of the crops to reduce the stress of waterlogging of crops, recovering vitality of the root zone of the crops, fully-automatic during the whole process of working, and beneficial for popularization.

A pump arrangement comprising at least one first pump and at least one second pump that can be connected or is connected in series behind the first pump. The pump arrangement has a simple construction, lowest possible pump capacity requirements, and quickly establishes a required pressure or vacuum pressure. This is achieved in that a pump capacity of the first pump or a sum of the pump capacities of the first pumps is much greater than a pump capacity of the second pump and that a bypass with a first overflow valve is connected between the first pump and the second pump.

The invention discloses laminated board hot-pressing equipment with an automatic material laying device. According to the technical scheme, the equipment comprises a discharging conveying belt, the discharging conveying belt is provided with an automatic material laying device used for spreading decorative fabric, the automatic material laying device comprises a supporting shaft which is horizontally arranged above the discharging conveying belt, the peripheral surface of the supporting shaft is rotationally connected with a decoration fabric, and the two ends of the supporting shaft are provided with a driving mechanism for driving the supporting shaft to slide above the discharging conveying belt and used for laying the decorative fabric, and a guide cutting mechanism which is fixedly connected with the supporting shaft and used for guiding the decorative fabric and cutting the decorative fabric is arranged below the supporting shaft; and a positioning assembly for fixing the end part of the decorative fabric is further arranged on the discharging conveying belt. The laminated board hot-pressing equipment with the automatic material laying device has the advantages that the automatic material laying device is provided, so that the decorative fabric is laid more automatically, the labor consumption is reduced, and the hot-pressing efficiency of the laminated board is improved.

The invention relates to an orchard real-time spraying-feeding-maintaining multiple-robot system which mainly comprises a monitoring center (1), orchard spraying robots (2, 3), a feeding robot (4) and a maintaining robot (5). The organization structure of the system is a layered structure. The monitoring center (1) is arranged on the upper layer and all the robots are arranged on the lower layer.
