The invention discloses an aluminum profile quenching and cooling device, which comprises a bottom frame and a box body. The top of the bottom frame is fixed with a box body, and a feeding box is arranged inside one side of the box body. The sliding plate and the second sliding plate drive the heated aluminum profile to move from the chamber on the left side of the box to the chamber on the right side of the box body, and complete cooling in the chamber on the right side, which saves the time spent on manual pick-and-place and improves work efficiency ;By setting a rack and telescopic cylinder in the chamber on the right side of the box, the rack and gear are used to drive the aluminum profile to reciprocate and rotate, so that the cooling water is fully and evenly sprayed on the surface of the aluminum profile, which solves the problem of uneven cooling when the aluminum profile is quenched As a result of the problem that the quenching quality of aluminum profiles is reduced, the structure of the whole device is simple and compact, and it is easy to operate, which improves the production efficiency and reduces the labor intensity and the risk of personal injury.

The invention provides an inner circulation-type pressure-stabilization tumor hydrops drainage device, which comprises a tubular body, the left side of the tubular body is fixedly inserted with a drainage needle, the inside of the tubular body is plugged with a plug head, a push rod is fixedly connected to the right side of the plug head, a permanent magnet is fixedly connected to the inside of the plug head, an aluminum ring is slidably inserted into the inner portion of the tubular body, the inner portion of the tubular body is inserted with a speed measuring plate, and the bottom of the tubular body is fixedly connected with a liquid collecting tank through a conduit. When the push rod is pulled, the aluminum ring is moved by the permanent magnet, so that the speed measuring plate generates a certain amplitude displacement, the pulling rod is faster, the displacement of the speed measuring plate is larger, An indicator plate and a display panel on the speed measuring plate can directly determine the speed at which the medical staff extracts the tumor hydrops, and the speed of the extraction is adjust, so that the problems that the extraction speed is too fast, the pressure in the patient's body changes too fast, which leads to medical accidents such as syncope and even shock can be avoided.

The invention discloses a jacking device for bridge construction. The jacking device comprises a jacking device body, a pressing sleeve is fixedly connected to the top of the jacking device body, square sleeves are fixedly connected to four sides of the pressing sleeve, sliding sleeves are slidably connected to the inner parts of the square sleeves, and protecting sleeves which are located outsidethe square sleeves are arranged on the surfaces of the sliding sleeves in a sleeving mode. According to the jacking device for bridge construction, discs drive a screw to be connected into a threadedhole in a threaded mode to limit the sliding sleeves, and then the sliding sleeves protect a thin steel plate from the four sides of the pressing sleeve through limiting mechanisms and the protectingsleeves, so that the jacking device has the advantage that the thin steel plate of the top of the jacking device is prevented from falling down during installation, the problem that the thin steel plate is prone to sliding and falling when the thin steel plate is paved at the top of the jacking device due to the facts that the paved steel plates are comparatively many and the top of an existing jacking device is not provided with a certain protecting mechanism is solved, and a situation that the body of a user is prone to being hurt in the falling process of the steel plates is avoided at thesame time.

The invention discloses an impeller water-spraying oxygen-increasing machine, wherein a motor (11) is arranged above a support body (2), the support body (2) is connected to one end of a support rod (5) in a trisection mode, the other end of the support rod (5) is provided with a floating ball (9), a shaft of the motor (11) is provided with an impeller shaft (14) through a coupler (13), and the impeller shaft (14) is provided with an impeller (18). The impeller water-spraying oxygen-increasing machine is characterized in that a water outlet body (16) is arranged below the support body (2), the impeller shaft (14) penetrates through the centre of the water body (16), a water inlet cover (8) is arranged below the water outlet body (16), and the impeller (18) is positioned in a cavity formedby the water outlet body (16) and the water inlet cover (8). A spiral membrane on the water-outlet body enables the spraying water to be in a rotation state so that the water can contact with the airfor a longer time, the water and the air are further mixed, convection and exchange of a bottom-layer water body and an upper-layer water body are realized, and the oxygen-increasing capability is improved.
