The invention relates to the technical field of wearable intelligent devices, and in particular discloses an application method of an intelligent caring waist belt. The intelligent caring waist belt comprises a waist belt body, a shell, an air bag, an air cylinder and a controller, wherein the waist belt body is arranged at the upper end of the outer surface of the shell in a penetrating manner, the controller is arranged on the shell, the upper end of the air bag is connected with the shell, buckles are arranged on the two sides of the lower part of the air bag, an air inlet is arranged at the upper end of the air bag, and the air cylinder is inserted in the air inlet. The application method comprises the following steps of fixing the waist belt body to the waist of a wearer; folding theair bag to the position, near the waist, of the wearer in a manner of winding from bottom to top; buckling the buckles on the two sides around the wearer; and enabling a controller to control the aircylinder to be opened for carrying out air inflation on the air bag, so that the air bag is downwards unfolded. For the application method of the intelligent caring waist belt provided by the invention, the air bag in the waist belt is unfolded downwards after being inflated for surrounding the lower part of the wearer, and thus the protecting effect on the wearer is improved.

The invention discloses a telescopic-arm blocking crossing rack, and belongs to the technical field of power line engineering. The telescopic-arm blocking crossing rack comprises rack bodies and blocking devices, wherein the rack bodies are arranged at two sides of a crossed object, the blocking devices are connected to the rack bodies, each rack body comprises a vertical post, a rotation support seat, a mast and rack body fixing pull lines, the vertical posts are arranged at the two sides of the crossed object and are fixed by the rack body fixing pull lines, the rotation support seat is connected between the mast and the vertical post, each blocking device comprises a telescopic arm, a balancing arm and a blocking rod system, the telescopic arm and the balancing arm are respectively and symmetrically arranged at two sides of the rotation support seat, a blocking rod system is attached onto the telescopic arm, and the blocking devices at the two sides of the crossed object are abutted in the air by the telescopic arms. By the telescopic-arm blocking crossing rack, rapid blocking can be achieved in the air, the blocking power-failure running time is short, a bearing framework crossed by blocking is of a rigid structure and is high in stability, the crossed object can be protected very well, meanwhile, broken line impact can be borne, the crossed object is protected within the rigid framework, and the safety guarantee during circuit crossing is improved.

The invention relates to a packing machine capable of preventing paste from solidifying and convenient in stuffing of material injecting type paste. The packing machine comprises a mixing barrel and water pumps, wherein an electric motor is connected to the middle part of the top end of the mixing barrel; the mixing barrel and the electric motor adopt a vertical structure; a main shaft is mountedat the middle part of the bottom end of the electric motor; the electric motor is movably connected with the main shaft; stirring blades are arranged on the left side and the right side of the main shaft; and the main shaft is fixedly connected with the stirring blades. The packing machine disclosed by the invention has the beneficial effects that the water pumps are started, so that liquid in water tanks can be poured into the mixing barrel; internal paste cleaning can be performed on the main shaft, the stirring blades and mesh hood rods, so that the situation that after a long term, the paste solidifies can be prevented; through a moving groove between each water rod and the corresponding water pump, the paste can be prevented from entering the water tanks; and the moving groove is clamped between each water pump and the corresponding water rod, so that the liquid can be blocked from entering the mixing barrel, and internal cleaning can be performed on the mixing barrel at any timethrough the moving grooves.

The invention relates to an anti-embolism protection device and a medical instrument. The anti-embolism protection device includes a support frame and a filter element, and the support frame includes a main body, and a first support part and a second support part connected with the distal end of the main body. The first support part is located below the second support part, and in an unfolded state, the first support part is bent downward of the main body part. The filter element covers the main body part and the second supporting part. The above-mentioned anti-embolism protection system and medical device have good coverage and high stability.

The invention provides an airbag device for protecting knees and legs, which comprises a module frame. An air bag and a decoration cover for air charging system are arranged in the module frame, and a decoration cover is arranged on the module frame. The invention is characterized in that the two secondary air chambers are symmetrically arranged at two sides of the lower part of the air bag, anda notch is provided in the middle area of the lower part of the air bag; the two secondary air chambers are respectively folded into a main air chamber at the upper part of the air bag; an isolation strip is respectively arranged between the secondary air chambers and the main air chamber. When the air charge is performed, the main air chamber arranged at the upper part of the air bag is first fully charged to ensure the protection for the knees. Then, the main air chamber is continuously charged to extend the secondary air chamber so as to prevent the legs from directly contacting with the lower part of a dashboard, thereby reducing the harm to the legs, simultaneously increasing the contact area between the legs and the knees, and protecting the legs and the knees more effectively. As the broken notch is provided in the middle area of the lower part of the air bag, the airbag is kept away from the decoration cover when being extended, thus ensuring that the air bag is extended in the required direction.

The invention discloses an impingement and air-film cooling structure adopting variable-hole array pitches used for a wall surface of a jet tube. The impingement and air-film cooling structure comprises an end wall, an outer side wall and an inner side wall. Impingement holes are formed in the outer side wall. Air film holes are arranged in the inner side wall. A cooling cavity is arranged between the inner side wall and the outer side wall. Cooling air flow flows into the cooling cavity by passing through the impingement holes for forming impingement cooling of the inner side wall. Air flow in the cavity converges into hot air by passing through the air film holes. An air film is formed in the surface of the inner side wall. By adopting the air film holes with inclination angles, the contact area between cold flow and the inner side wall is increased, thereby increasing cooling efficiency. The array pitch P of the air film holes varies with the formula P2_n equal to 1.15nP2_1. The impingement holes are located in the middle of two rows of the air film holes. The impingement and air-film cooling structure adopting variable-hole array pitches used for the wall surface of the jet tube has following beneficial effects: the cooling structure is easy and facilitates machining; without increasing cooling air, cooling distribution of an air film plate is more uniform, thereby increasing cooling efficiency; and infrared radiation characteristics of the wall surface of the jet tube are thus reduced.
