Description

Technical Field

[0001] This utility model relates to the field of power production, specifically to a portable air exchanger for use in enclosed spaces in water conservancy production. Background Technology

[0002] A confined space is a limited space that is relatively isolated from the outside world, with restricted entrances and exits, poor natural ventilation, and sufficient to accommodate one person for unconventional and non-continuous work. Working in confined spaces carries risks of poisoning, asphyxiation, explosion, fire, falls, drowning, collapse, electric shock, mechanical injury, and burns. Poisoning and asphyxiation are among the most common. In power production operations, hot work generates fumes and toxic gases. Furthermore, during the maintenance of wind tunnels, spiral casings, and tailrace pipes, the maintenance environment is a confined space without ventilation, posing a risk of asphyxiation. Therefore, installing air exchangers in confined spaces can effectively prevent the risk of asphyxiation. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution:

[0004] A portable air exchanger for use in enclosed spaces in water conservancy production includes a housing, with an air inlet pipe and an air outlet pipe fixedly connected to the left and right side walls of the housing, respectively; a fan is fixedly installed on the left inner wall of the housing corresponding to the air inlet pipe.

[0005] The inner cavity of the enclosure is equipped with a storage battery.

[0006] A carrier frame is installed at the bottom of the inner cavity of the box. The carrier frame includes a base plate, which is fixedly connected to the bottom of the inner cavity of the box. A fixed shell with a top opening is fixedly connected to the top of the base plate. A matching movable block is inserted into the top opening of the fixed shell. A connecting plate is fixedly connected to the top of the movable block. A damper is fixedly connected to the bottom of the movable block. The bottom of the damper is fixedly connected to the bottom of the inner cavity of the fixed shell.

[0007] A battery is connected to the top of the connecting plate.

[0008] A handle is installed on the top of the outer side of the box.

[0009] A telescopic rod is fixed to the back of the box. The telescopic rod includes a sleeve and a rod. The sleeve and rod work together with a pin to achieve extension, retraction, and adjustment.

[0010] The box has a removable cover on one side.

[0011] The box is fixedly connected to four corners at the bottom.

[0012] The outer end of the air intake pipe is fixedly connected to a fixing ring, and the outer wall of the fixing ring has multiple evenly distributed connection holes.

[0013] The fan and the battery are connected by wires.

[0014] The beneficial effects of this utility model are as follows:

[0015] This application provides a portable air exchanger for use in enclosed spaces. When in operation, it uses a fan to draw outside air into the enclosed space, thereby ensuring that workers have sufficient air and avoiding suffocation.

[0016] By installing casters at the bottom of the box and telescopic rods on the side walls, the box can be moved by holding the telescopic rods and using the casters, making it easy to carry and move.

[0017] By mounting the battery on the carrier, the vibration generated during the movement of the battery box can be absorbed by the damper, thereby achieving a shock absorption effect. This helps to reduce the impact of vibration on the battery and extend its service life. Attached Figure Description
