The invention discloses a high-strength tent for polar exploration, which belongs to the field of polar tents. It is a high-strength tent for polar exploration. In this scheme, when too much snow is accumulated on the upper end of the outer reinforcement curtain, the snow board is used to store the snow under the weight of the snow. Under the action, it moves downward and drives the limit slider to move, triggers the trigger switch, starts the electric heating plate, heats the external reinforced curtain, melts the snow on the upper end of the external reinforced curtain, and makes a liquid layer between the external reinforced curtain and the snow. To reduce the friction between the snow and the outer reinforced curtain, so that the snow can slide down from the outer reinforced curtain under the action of its own weight, which can realize the timely cleaning of the snow with less energy without affecting On the premise of the normal operation of the life safety device in the tent, the snow in the tent should be cleaned up in time, so that it is not easy to threaten the whole tent due to the heavy snow on the tent, and it is not easy to cause a safety accident of the tent collapse.

The invention provides an U-shaped steel reinforced composite anchor net support structure for a high-stress soft rock tunnel of a deep well and a construction method thereof. The construction method comprises the following steps of firstly, punching an anchor bolt and an anchor cable into a surrounding rock, supporting the surrounding rock, and exposing with setting lengths; then, sequentially paving and hanging a polyester fiber net and a reinforcement net on the exposing parts of the anchor bolt and the anchor cable, tightly paving the polyester fiber net onto the surrounding rock, tightly paving the reinforcement net onto the polyester fiber net, building an U-shaped steel bracket, enabling the anchor bolt and the anchor cable to sequentially penetrate through the polyester fiber net and the reinforcement net, and fixing on the reinforcement net by trays and screw caps; casting a concrete spray layer to seal the whole support structure. The construction method has the advantages that by using the U-shaped steel bracket, the reinforcement net and the polyester fiber net as skeletons, and forming a reinforced concrete sealing structure with the concrete spraying layer, the flexibility and pressure relief functions of the polyester fiber net are utilized, the pressure of the surrounding rock is uniformly distributed into the whole support system, and the active support property of the anchor bolt and anchor cable, and the passive support property of the reinforcement net and the U-shaped steel bracket are fully utilized.

The invention discloses a device for clearing sputum-thrombus formed in the lung of a patient, especially sputum-thrombus formed in the bronchium of a child. The sputum-thrombus clearing device comprises a hollow sheath catheter with certain flexibility and at least one guide wire which is made of a flexible material and arranged in the hollow sheath catheter and can extend out of or retract into the hollow sheath catheter, the diameter of the guide wire is smaller than the inner diameter of the hollow sheath catheter, one end of the guide wire is fixed to an operation handle at one end of the hollow sheath catheter, and the guide wire can be driven to rotate axially by rotating the operation handle and can be driven to extend out of or retract into the hollow sheath catheter relative to the axial direction of the hollow sheath catheter by pulling or pushing the operation handle. The device can reach any lung segment under the guide of a bronchoscope, the sputum-thrombus can be wound on the device under gripping force generated in a relatively large area due to rotation of the guide wire, breaking of the sputum-thrombus is not prone to occur and the whole sputum-thrombus can be pulled out intactly. The intervention device has good economic benefits and social benefits after being applied clinically.

The invention provides a method for processing thermoplastic elastomer by utilizing waste rubber and relates to the technical field of thermoplastic elastomers. By adopting the method for processing the thermoplastic elastomer by utilizing the waste rubber, on one hand, the waste rubber is recovered and then is processed into modified rubber powder, so that waste resources are very well optimized and configured, and the ecological environment is protected; on the other hand, the processed waste rubber powder is used as a main material, and natural plant fibers such as bagasse fiber and jute fiber and other rubber performance reinforcing agents are used as auxiliary materials, the prepared thermoplastic elastomer has the good properties of large hardness, large tensile strength, high elongation and high heat resistance, the safety of the thermoplastic elastomer material applied to electric wires and cables is ensured, and the service life of the electric wires and cables is prolonged.
