Abstract: This present invention is related to a method of collecting high-level radioactive contaminated uranium powder underwater. It utilizes a long rod fixed to the pipe of the sewage pump at bottom, and takes another end of the sewage pump to connect to the sediment bag to collect uranium powder which is dispersed and contaminates the pond. Inhaling the pond water contains uranium powder into the sediment bag by sewage pump that is joined to a collecting can under it and waiting for precipitation of the powder. When the uranium powder in the sediment bag is completely precipitated into the collecting can, operator can utilize submersible pump to drain the pond water from the sediment bag. Operator may hold the cable wire of the uranium powder collecting can manually to move it to the collecting shelf and repeat the process several times until the high-level radioactive uranium powder in the contaminated pond are all collected on the uranium powder collecting shelf.

Abstract: A brake device for a strap-reel frame is installed on the frame body of the strap-reel frame for braking the inner and the outer disc pivotally fitted on the horizontal shaft of the frame body. The brake device includes a swinging rod having one end pivotally connected with a preset portion of the frame body above the horizontal shaft and able to be actuated to swing downward by its own gravity. The swinging rod has its intermediate portion fixed with two brake blocks able to be moved downward together with the swinging rod to push against the outer circumferential edge of the inner disc and stop the inner disc from rotating.

Abstract: A membrane reel fixing device for a membrane strapping dispenser includes a reel pivot having its outer circumference formed integral with three support ribs respectively connected with a convex holding plate extending along the circumference of the reel pivot. The three holding plates have their lower sides suspended in midair; therefore, when pressed diametrically, the holding plates can be elastically shifted and deformed and after a membrane reel is fitted on the reel pivot, the holding plates can firmly prop the inner wall of the central tube of the membrane reel. Different-sized membrane reels can be firmly fitted on the reel pivot by means of the holding plates that can be elastically shifted and deformed.

Abstract: A membrane packing dispenser includes a rotary shaft sleeve and a holding sleeve. The cylindrical portion of the rotary shaft sleeve is step-shaped and formed with a lower portion to be fitted with a membrane reel and an upper portion for receiving the cylindrical portion of the holding sleeve. The lower portion of the rotary shaft sleeve has its outer wall bored with plural slots respectively disposed therein with a tightening plate having its upper opposite sides respectively fixed with an engage projection. Thus, the lower portion of the rotary shaft sleeve can be firmly engaged with the end of a membrane reel by the engage projections of the tightening plates. The engage projections can be elastically adjusted to shift; therefore, the rotary shaft sleeves are applicable to various membrane reels with a little difference in size.
