The present application provides a kind of bamboo planting cutter device and cutting method, it is related to bamboo branch and leaf harvesting technical field, including cutter handpiece, the cutter handpiece is installed with telescopic positioning piece;The telescopic positioning piece is used to prevent pulling down bamboo branch;Telescopic positioning piece is installed with shear control part;The shear control part is used to prune bamboo branch;Two bamboo branch positioning pieces are fixedly installed on shear control part;Electric cutting bamboo branch can be adopted shear control part, is more labor-saving fast, improves bamboo branch harvesting efficiency, simultaneously, the present structure adopts telescopic positioning piece when cutting bamboo branch, can prevent artificial pull down shear control part or under the action of support rod self-weight pull down shear control part, easy to cause bamboo branch and the ingrowth site of main stem, that is, bamboo knot place split;To solve the problem that current bamboo planting cutter device is not convenient for preventing pull down protection, also inconvenient for bamboo branch at cut-off place to smear lime mortar sterilization protection.

This invention relates to the field of intelligent transformer technology, specifically to an intelligent transformer with protective functions, including a transformer main body, a pressure relief mounting component installed on the transformer main body, and a pressure relief device installed on the pressure relief mounting component; the pressure relief mounting component is used to detect the oil level; the pressure relief device is used to release air pressure; a moisture-absorbing component is installed on the pressure relief mounting component; a fin detection component is installed on the transformer main body; the fin detection component is used to monitor fin deformation; the pressure relief device can be used to release pressure in a timely manner when the insulating oil and air pressure inside the transformer main body rises, which can ensure the safe operation of the transformer main body. At the same time, this structure uses a float to monitor the insulating oil level, and in conjunction with a control switch, it can automatically control the oil discharge through the discharge solenoid valve, and the oil discharged by the discharge solenoid valve contains a large amount of sediment impurities.

The application discloses a dangerous wastewater multistage treatment device and relates to the technical field of wastewater treatment. The device comprises a first aeration part, two tubular aeration parts are installed on the first aeration part, the two tubular aeration parts are respectively used for aeration treatment of wastewater, two second liquid supplementing parts are respectively installed on the two tubular aeration parts, the second liquid supplementing parts are used for wastewater conditioning, a gas supply connecting part is installed on the first aeration part, a drainage detection part is installed at the bottom of the first aeration part, the water level is monitored by using the drainage detection part, the time delay control of the time delay switch is matched, when it is necessary to control the aeration pipe to suspend aeration discharge, the worker can preferentially operate to complete the cleaning water body replacement work, and the aeration pipe or the three-way pipe inside is prevented from being blocked or corroded due to impurities in the wastewater and other factors, so that the problem that current dangerous wastewater aerators cannot automatically control the closure of the aerators and flushing protection before stopping aeration is solved.

This invention provides a water treatment device for aquaculture, belonging to the field of aquaculture water treatment technology. It includes an ultraviolet (UV) sterilization unit with a sealed water delivery component, used for defoaming and sterilization; a mixing auxiliary component is installed on the sealed water delivery component to improve the sterilization quality of the aquaculture water; a self-cleaning unit is installed inside the UV sterilization unit; and an anti-pressure-locking component is installed on the UV sterilization unit. This invention, by setting up a UV sterilization unit, can achieve negative pressure suction. Combined with the slidably adjustable sealed water delivery component, it can achieve diverted, quantitative, and sealed UV sterilization of aquaculture water, thus improving sterilization quality. This solves the problems of existing aquaculture water treatment equipment being inconvenient for independent sterilization and the interference of large amounts of foam and scum in the water with UV sterilization.
