An escape device (10) including a cable (18), a rotatable cable dispensing assembly (22) from which the cable (18) is dispensed under load, a braking mechanism (28) operatively connected to the rotatable cable dispensing assembly (22), whereby a braking response of the braking mechanism (18) is proportional to the rate at which cable (18) is dispensed from the rotatable cable dispensing assembly (22).

The invention relates to a hydrological monitoring device, which comprises a cylindrical first cylinder and a second cylinder arranged side by side, a one-way pay-off mechanism is fixedly arranged at the bottom of the first cylinder, and a floating ball is arranged in the second cylinder. The diameter of the floating ball is smaller than the inner diameter of the second cylinder. The first cylinder and the lower part of the second cylinder are provided with a plurality of water inlets, and the outside of the water inlets is provided with a protective device. The one-way pay-off mechanism includes a shell and a The rotating shaft and the first winding wheel fixedly arranged on the rotating shaft, both ends of the rotating shaft are connected with the casing through bearings, a ratchet wheel is fixedly arranged on the rotating shaft, and a pawl matching the ratchet wheel is arranged inside the casing. The first pulley is set on the first pulley; the first pulley is set on the top of the first cylinder, the second pulley is set on the top of the second cylinder, and the top of the first pulley goes around the first pulley, the second pulley and the floating ball in turn. top connection.

The invention provides a rice quantitative packaging device, which relates to the field of rice packaging. The rice quantitative packaging device includes a feeding hopper, a first processing mechanism is arranged below the feeding hopper, the upper end of the first processing mechanism is fixedly connected with the feeding hopper, and a second processing mechanism is arranged below the first processing mechanism , the upper end of the second processing mechanism is fixedly connected with the lower end of the first processing mechanism. The rice quantitative packaging device, by setting the feeding hopper, the first processing mechanism and the second processing mechanism, the rice can enter the interior of the device through the feeding hopper, the rice can be rotated and descended through the spiral blade, and can be sent to the small net through the ventilation pipe. The inside of the ring is inflated to achieve the effect of cleaning the impurities in the rice when packaging the rice, which solves the problem that the rice packaging device in the prior art does not handle the impurities in the rice thoroughly when packaging the rice. There is a quality problem with the rice.

The invention discloses a pile pulling device and a pile pulling construction method thereof. There are multiple groups of claws on the pile device which are driven by the oil cylinder and can protrude toward the center of the pipe to form a plurality of claws that support or cut off the waste piles. There are several alloy teeth on the inner surface of the claws. The solenoid valve and oil pipe are connected to the oil pump and oil tank on the combined power pile machine; there are multiple high-pressure water nozzles at the bottom of the sleeve type pile extractor, and the high-pressure water nozzles are connected to the combined power hole forming machine through the solenoid valve and high-pressure water pipe. The pile driver is connected with the water pump of the water source; the oil cylinder is also provided with a distance sensor for detecting the downward elongation of the piston rod, and the distance sensor is electrically connected with the controller. The convex column is accurate and reliable for the bottom of the waste pile, the construction noise is small, and the waste pile is pulled out after one-time rotation or cutting, saving time and effort, the construction period is short, and the construction efficiency is high.

The invention provides a wind-resistance roller shutter drawing mechanism, belonging to the technical field of machinery and solving the problem that the traditional roller shutter is not smooth to slip due to the effect of wind. A wind-resistance roller shutter of the wind-resistance roller shutter drawing mechanism comprises curtain cloth, a window cover, a reelpipe, side rails and a lower rod, wherein the upper end and the lower end of each side rail are respectively provided with a cloth-guiding top plug and a side rail bottom plug; the wind-resistance roller shutter drawing mechanism is arranged in the side rails and comprises a movable pulley bracket, a drawing part and an elastic compensating part, wherein the upper end of the compensating part is connected with each cloth-guiding top plug, the movable pulley bracket is suspended at the lower end of the compensating part, one end of the drawing part is connected with the reelpipe, and the other end of the drawing part penetrates through the cloth-guiding top plugs, extends downwards to stride pulleys on the side rail bottom plugs, extends upwards to stride a pulley on the movable pulley bracket, then extends downwards to stride other pulleys on the side rail bottom plugs and finally extends in an obliquely upward manner to be fixed on the lower rod. The wind-resistance roller shutter drawing mechanism disclosed by the invention has the advantages of simple structure, stability, reliability and good guiding property.

Flying artefact and its device for aerial advertising to be pulled from the surface or tied up to a fixed point, which includes an element of elevation and suspension in the air (1) with advertising medium function, built in a very light and resistant material, with the shape of an aerodynamic profile, which has an opening (4) at its front part reinforced with light and resistant tubes, and an opening (5) on its back, which has a curved upper surface (6) and a flat lower surface (7), and which acquires its shape when the air passes through its four walls; a pulling or clamping line (3) which is tied up to the chosen pulling means or fixed point; at least two ropes (2) that connect the pulling or clamping line (3) with the front opening (4); the advertising material being placed on both sides and all along the element of elevation and suspension (1).
