The invention discloses a flame-retardant low-heat-release type gas extraction drilled hole plugging material, which comprises a component A and a component B, wherein the component A comprises the following raw materials in parts by mass: 45 to 75 parts of polyether polyol 1, 5 to 15 parts of polyether polyol 2, 15 to 30 parts of mannich polyols, 1 to 5 parts of polyester polyol, 0.01 to 3.0 parts of catalyst, 1.5 to 3.0 parts of foam stabilizer, 1.0 to 6.0 parts of foaming agent, 10 to 30 parts of flame retardant and 0.5 to 1.5 parts of stabilizer; the component B is multi-methylene multi-phenyl polyisocyanates; and the mass proportion of the component A to the component B is 100:(100-200). The plugging material can meet a requirement of the conventional hole plugging construction process; and the prepared plugging material has the characteristics of low reaction release heat, small water foaming rate, high flame retardant, high mechanical property and the like.

The invention relates to a star sensor with a large field of view. In order to solve the problem that when the existing star sensor adopts a small field of view imaging system, it needs to be used in conjunction with a tracking platform. However, the existing design based on a similar compound eye structure also has system integration. To solve the problem of insufficient integration, a bionic compound eye-based star sensor with a large field of view is provided, which includes a spherical lens group unit, an optical conversion unit, and a data processing unit arranged in sequence along the optical path; the spherical lens group unit includes a supporting shell and multiple multiple lens groups are installed on the supporting shell and are set independently of each other, the incident surface is distributed on the spherical surface of the supporting shell, and the incident optical axis points to the center of the sphere where the front spherical surface of the supporting shell is located, forming a joint The field of view at a preset angle; the optical conversion unit includes a plurality of coaxially arranged lenses, and the optical axis passes through the center of the sphere where the front spherical surface of the supporting shell is located; the data processing unit is used to receive continuous plane images and convert them into discrete Digital image from which stellar centroid points are extracted.

The invention discloses efficient and environment-friendly processing equipment for a rusty hardware plate. The processing equipment comprises a bottom plate, a support device located above the bottom plate, a first clamping device arranged on the support device, a second clamping device located above the first clamping device, an electric cylinder device arranged on the bottom plate, an abutting device located on the right side of the support device, a motor device and a rotating device arranged on the support device and an elastic device arranged above the support device. According to the processing equipment, the rust removing operation can be carried out on the upper surface and the lower surface of the rusty hardware plate at the same time, so that the rust removing efficiency is high; moreover, the hardware plate can be clamped stably, so that a sufficient supporting effect is achieved for the hardware plate; and the operation is simple, the use is convenient, the labor intensity of workers is low, meanwhile the rust can be removed uniformly, and the rust removing effect is remarkable.

The invention discloses a rotary lifting device for micro-power electric equipment, which comprises a right-angle steel pipe frame, a movable pulley block, a rope and a driving mechanism. A hoop is arranged on the rod, a driving mechanism is arranged at the upper end of the upper rod, a movable pulley is arranged in the middle of the upper rod, one end of the rope is fixed on the upper rod, and the other end passes through the movable pulley to connect with the driving mechanism; The pulley block includes a movable pulley lifting module, and the number of the movable pulley lifting modules is five, and the movable pulley lifting modules are arranged side by side in turn, and one end of the rope of the previous movable pulley lifting module is connected with the movable pulley lifting hook in the latter movable pulley lifting module, and the rope The end is connected with the driving mechanism; the invention is small in size and can adapt to the narrow working environment, so that it can realize the lifting of heavy objects under the situation that it is not easy to use large-scale lifting equipment; it is worthy of popularization and application.
