The invention relates to a hybrid multi-rotor aircraft with retractable wings, and mainly solves the problems in the prior art that the time of endurance is short and the load capacity is limited due to causes of structure. The hybrid multi-rotor aircraft with retractable wings mainly comprises motors, propellers, rocker arms, an aircraft body, a lithium battery pack, the retractable wings, retractable undercarriages and a flight control system; the assembly scheme of all the parts lies in that the propellers are mounted on the motors; the motors are fixed at one ends of the rocker arms through installation parts, and the other ends of the rocker arms are fixed in the middle of the aircraft body; the flight control system is mounted at the central position right above the aircraft body; the lithium battery pack is mounted at the central position under the aircraft body; the retractable undercarriages are symmetrically mounted at positions, close to the two sides, below the aircraft body; the retractable wings are fixed on the retractable undercarriages through installation parts. After the aircraft takes off, the undercarriages can be retracted, and at the same time the wings stretch towards outer sides, therefore the lift force of the multi-rotor aircraft is greatly increased, the time of endurance is prolonged, and the load capacity is further improved.

The invention discloses a bone malformation correction or fracture reduction and fixation device and a method for processing the same. The bone malformation correction or fracture reduction and fixation device comprises external fixation brackets or one and more external fixation plates, wherein the external fixation brackets or the external fixation plates are used for fixing fixation needles inserted into the bone tissues; at least one end of each fixation needle is exposed outside the skin, and the exposed end of the fixation needle needs to be fixed; the external fixation brackets consist of a first fixation bracket and a second fixation bracket; the external fixation plates are used for fixing all the fixation needles inserted into the bone tissues needing to be fixed. The method for processing the bone malformation correction or fracture reduction and fixation device comprises the following steps of: (1) collecting the information of an image before reducing the bone; (2) reducing the bone virtually by using a computer; (3) designing the structure of the bone malformation correction or fracture reduction and fixation device; and (4) processing the bone malformation correction or fracture reduction and fixation device. The bone malformation correction or fracture reduction and fixation device provided by the invention has a function of automatically reducing the bone, is reasonable in structure, has a good bone fixing effect and can be used for effectively overcoming the defects of difficult bone malformation correction or fracture reduction, complex operation on malformed or fractured bone and excessive dependence on the clinical experience of a doctor of the existing bone malformation correction or fracture reduction and fixation mode.

The invention relates to the technical field of cable assembly equipment, and discloses a prefabricated distribution network civil engineering cable well assembly combination. The combination comprises joint clamping pillows and prefabricated ducts, wherein each joint clamping pillow comprises a pillow block at the bottom and pillow arms which are arranged at the two sides and perpendicular to thepillow block, the two ends of the prefabricated ducts are clamped and fixed by the joint clamping pillows, prefabricated side plates on the two sides of every two adjacent joint clamping pillows areconnected and fixed, a plurality of cable ducts are arranged inside the prefabricated ducts, and the joint clamping pillows, the prefabricated ducts and the prefabricated side plates are all prefabricated into standard pieces in a unified specification by a factory. The prefabricated distribution network civil engineering cable well assembly combination has the beneficial effects that the assemblytype prefabricated pieces are produced through modern machinery of the factory, the product precision is high, the quality is stable, the construction schedule duration is greatly shortened, the process quality is guaranteed, on-site complex conditions can be avoided, the application range is wide, the operation safety risk is greatly reduced, and the influence on the life of surrounding people is greatly reduced.

The invention relates to a dynamic house onsite reconstruction time and area determining method of a subsidence area, belongs to the field of mining-area house damage and onsite reconstruction, and solves the problems that a damaged village in a mining area is hard to resettle and house reconstruction needs long time. The land-surface dynamic subsidence process after exploitation of a mining areais analyzed, the subsidence deformation amount in the land surface caused by different exploitation sizes in the working face of the to-be-reconstructed area can be determined accurately, further, theresidual deformation amount of the land-surface subsidence area in the dynamic process is calculated quantitatively, compared with a house anti-deformation index, and the house onsite reconstructiontime and area in the mining process are determined. The anti-deformation house can be built as early as possible in the mining process, villagers whose houses are damaged by mining can live in new houses as early as possible, and the life quality of the villagers in the mining area is improved. The method can be used to scientifically and accurately guide house onsite reconstruction planning in the land-surface subsidence area in the dynamic mining process, and adversarial relation between workers and villagers in the mining area can be alleviated effectively.

The invention provides an X-ray capsule 3D endoscope system. The system comprises an in-vivo imaging capsule, an in-vitro signal transceiving device and an in-vitro image processing system, wherein the in-vitro signal transceiving device communicates with the in-vivo imaging capsule in a wireless mode; and the in-vitro image processing system is connected to the in-vitro signal transceiving devicein a wired or wireless mode, and the in-vitro signal transceiving device sends a control command to a capsule electronic system. The in-vivo imaging capsule is used for emitting radiation beams, detecting attenuation signals generated by the reflection of intestinal walls and intestinal contents and transmitting the attenuation signals to the in-vitro signal transceiving device; the in-vitro signal transceiving device is used for transmitting the received attenuation signal to the in-vitro image processing system; and the in-vitro image processing system is used for post-processing the imagesignals collected by the in-vivo imaging capsule. The endoscope system has the characteristics of safety, reliability, high detection precision and less influence on the normal life of patients.

The invention discloses an access control intercom system as well as an interaction method and device of the access control intercom system. The method includes the following steps that: an interaction call request is transmitted to an interaction terminal through a wireless communication manner according to a first operation instruction of a user of an access control machine; and a second operation instruction from a user of the interaction terminal is received, and whether a door lock corresponding to the access control machine is to be opened is determined according to the second operation instruction. According to the access control intercom system as well as the interaction method and device of the access control intercom system of the invention, interconnection of the access control machine and the interaction terminal can be realized; the user of the access control machine transmits the interaction call request to the interaction terminal in a wireless communication manner, and the user of the interaction terminal returns an instruction for indicating whether the door lock is to be opened through a wireless communication manner, and the whole process is proceeded through a wireless manner, and the life of the user is just slightly affected, and an operation process is simple.
