The utility model relates to a gas-collecting hood technology, and discloses an energy-saving and environment-friendly gas-collecting hood. Comprising a gas-collecting hood body, a breather pipe is installed above the gas-collecting hood body, the upper end of the breather pipe is connected with a dust collector through a dust collecting pipe, a dust collecting fan is installed on the dust collector, a gas outlet of the dust collecting fan is connected with a gas outlet pipe, the gas outlet pipe is communicated with a gas absorption tower, and a multi-layer spraying structure is installed in the gas absorption tower. The sulfur dioxide waste gas is sucked into the dust collector by the dust collection fan, dust in the waste gas falls to the bottom of the dust collector due to gravity, other waste gas enters the gas absorption tower from a gas outlet of the dust collection fan along a gas outlet pipe to be treated, a multi-layer spraying structure is arranged in the gas absorption tower, and the sulfur dioxide waste gas is neutralized and diluted by spraying an alkaline solution; qualified treated gas is emptied through an emptying pipe, and waste liquid generated after spraying is discharged from a waste liquid outlet pipe for retreatment, so that the situation that the waste gas is directly and freely diffused without any treatment and seriously pollutes the working environment and the atmosphere is prevented.

The invention discloses a self-repairing speed bump based on vehicle pressure power generation and a traffic light device. The self-repairing speed bump based on vehicle pressure power generation comprises a left round head unit, a right round head unit and a plurality of middle units, wherein the left round head unit and the right round head unit are oppositely arranged left and right; the middle units are arranged between the left round head unit and the right round head unit and are connected with each other; the middle unit comprises a base plate, a front check block, a rear check block, an upper cover body, a hydraulic power generation mechanism and a gear power generation mechanism, the front check block and the rear check block are oppositely arranged at the front end and the rear end of the base plate respectively, and the hydraulic power generation mechanism and the gear power generation mechanism are both arranged on the base plate and located between the front check block and the rear check block; according to the intelligent deceleration strip, electricity resources can be greatly saved, the vehicle speed is reduced, meanwhile, energy recycling is achieved, the durability and maintenance convenience of the deceleration strip are greatly improved by arranging the heating wire, and therefore the long-term maintenance cost is reduced, and the technical problem that an existing deceleration strip and traffic light device is single in function is effectively solved.

The utility model relates to the technical field of water sample detection sample storage, in particular to an environmental water sample detection sample storage device which comprises a box body, a switch plate is arranged at the top of the box body, two square blocks are fixedly connected to the inner side of the box body, one side of one square block is fixedly connected with a motor, and the other side of the square block is fixedly connected with a water pump. The output end of the motor is connected with an opening and closing mechanism, the opening and closing mechanism is fixedly connected with the switch plate, one side of the opening and closing mechanism is connected with a moving mechanism, the inner side of the box body is connected with a switch contact, the moving mechanism corresponds to the switch contact, and three lamp caps are fixedly connected into the box body. The opening and closing mechanism comprises a rotating shaft, the rotating shaft is rotationally connected to the output end of the motor, one side of the rotating shaft is fixedly connected with a first belt wheel, one end of the rotating shaft is fixedly connected with the moving mechanism, and the automatic opening and closing device has the advantages of being high in practicability and capable of being automatically opened and closed.

This utility model relates to the technical field of pickling devices and discloses an online circulating pickling device for hydraulic cylinders, including a pickling tank. A mounting plate is fixedly connected to one side of the pickling tank, a storage tank is fixedly connected to one side of the mounting plate, a mounting frame is fixedly connected to one side of the mounting plate, and a tank body is fixedly connected to the top of the mounting frame. When cleaning metal debris, the solution no longer enters the tank, thus the tilting plate and rotating shaft stop rotating, and the generator no longer energizes the electromagnetic rod. The motor's operation drives the threaded rod to rotate, which in turn drives the scraper to move downwards. The scraper scrapes the material from the outer wall of the electromagnetic rod, thereby scraping away the adsorbed metal debris. A sealing door is provided on the outer wall of the tank; opening the sealing door allows for the collection of the scraped metal debris, thus reducing the difficulty of cleaning and improving the efficiency of cleaning adsorbed metal substances.
