The invention discloses a patient caring bed with a turnover assisting function and a turnover assisting method thereof and belongs to the field of caring beds. The patient caring bed comprises a bed body frame, a bed plate, an ejection mechanism and a cloth winding mechanism, wherein the cloth winding mechanism comprises cloth winding rolls, a driving device and turnover cloth; the cloth winding rolls are arranged at the two sides of the caring bed; the driving device is used for driving the cloth winding rolls to rotate; the two ends of the turnover cloth are respectively and fixedly wound on the cloth winding rolls at the two sides; the turnover cloth between the two cloth winding rolls are laid on the bed plate; the ejection mechanism comprises two ejecting rolls positioned under the turnover cloth, an ejecting bracket for installing the ejecting rolls, an electric pushing rod arranged under the ejecting bracket and a guiding device. The invention also discloses the turnover assisting method of the patient caring bed. The patient caring bed and the turnover assisting method disclosed by the invention have the advantages that the inclination of the body of a patient is realized by utilizing the ejection mechanism and the cloth winding mechanism to assist serving staffs to turn over the patient, the turnover action is gentle, the comfort level of the patient is high, and the working intensity of the serving staffs is greatly reduced.

The invention discloses a tension gauge for physical experiments of senior high school students. The tension gauge comprises a tension gauge shell, a limiting sliding groove is formed in the side surface of the tension gauge, and an anti-shaking mechanism is mounted in the limiting sliding groove. The tension gauge is scientific and reasonable in structure and safe and convenient to use, under thelimiting action of the limiting sliding groove and a sliding block, a supporting plate is attached to a hook through a through hole, so that it is guaranteed that a rope and a connecting rod are keptin parallel after the hook extends out, it is guaranteed that the pulling direction and the initial direction of the tension gauge are the same, when the senior high school students make experiments,it can be always guaranteed that the pulling direction of the tension gauge is kept unchanged, it is guaranteed that the stress state and the initial state of an object are consistent, and the seniorhigh school students can learn the state after physical stress better. After a clamping rod is rotated, a clamping plate can be taken out, a rear cover can be dismounted conveniently, internal components of the tension gauge can be replaced and maintained conveniently, and the condition that part of senior high school students can not make experiments due to damage of the tension gauge is avoided.

The present invention relates to a thermal defocus compensation method, which includes obtaining a pre-stored thermal defocus curve of a projection device; wherein, the thermal defocus curve is a parameter obtained in advance that changes with the start-up operation time of the parameters of a plurality of projection device sample machines. The time curve is obtained by fitting the parameter-time curves of all the projection equipment sample machines; according to the thermal defocus curve, the focusing scheme of the projection equipment is determined. The present invention can predict the degree of thermal defocusing of the projection equipment in advance, and determine the focusing scheme of projection in advance according to the degree of thermal defocusing of the projection equipment, so as to prevent the user from seeing unclear pictures and avoid interfering with the normal use of the user. satisfaction. The invention also relates to a storage medium and a projection device.

The invention provides an outdoor anti-collision communication antenna. The antenna comprises a base, an antenna equipment body, a remote driving mechanism for driving long-distance flying birds and asound amplification driving mechanism for driving flying birds falling near the antenna equipment, wherein the antenna equipment body comprises a parabolic antenna and a feed source; a supporting rodis fixedly installed on the antenna device body, and the surface of the supporting rod is fixedly connected with the surface of the base. The invention relates to the field of antennas. According tothe antenna, the remote flying bird repelling and short-distance flying bird repelling are combined, so the multi-protection for the communication antenna is achieved; the two driving mechanisms supplement each other, the normal use of the communication antenna is not disturbed, and the anti-collision capability of the communication antenna can be improved, so the problems that most common communication antennas are exposed outdoors, are limited by the antennas, are easily impacted by flying birds and easily inhabit the flying birds, and the normal use of the communication antenna is greatly influenced by activities of the flying birds are effectively solved.

A refrigerator equipped with a water tank that is easily accessible to a user and a method of using the same. A water dispenser is installed on the front side of a refrigerator. A water tank coupled to the water dispenser is detachably installed on a lower inner inside of a refrigerator door such that a user can conveniently observe the state of the water tank and access the water tank for maintenance and refill.
