And calculating the sampling distance from the detection region to the boundary of the forest region, calculating an overall sampling coefficient according to the number of the detection regions in each cluster and the sampling distance, determining the size of the detection regions, and selecting a calculation mode of the carbon sink amount according to the sampling distance of the divided detection regions.

This utility model relates to the field of slope support technology, and more particularly to a slope support device for deep foundation pit excavation adjacent to desert areas. It includes an installation plate; and also includes slids formed on the left and right sides of the top of the installation plate. A sliding plate is slidably connected inside the slids, and a rotating shaft is connected to the front end of the sliding plate. A connecting block is rotatably connected to the outer end of the rotating shaft, and a support frame is connected to the end of the connecting block away from the rotating shaft. A traction frame is connected to the top of the sliding plate, and a roller is rotatably connected to the upper front side of the installation plate. The roller is movably connected to the support frame. A positioning groove is formed on the top of the installation plate. The sliding plate slides on the slids, driving the rotating shaft to move. This utility model, through the cooperation of the slids and sliding plates, allows the support frame to move forward along the slids and naturally droop through the rotating shaft. This enables positioning and fixing within a safe area of ​​the slope before commencing support work, reducing personnel operation in dangerous areas and improving the safety and efficiency of the support process.

The utility model discloses a kind of quick hydraulic support pushing oil cylinder fixing pin devices under narrow space condition, it is related to hydraulic support pushing oil cylinder dismounting technical field, including hand pole, connecting rod and galvanized combined sleeve, hand pole one end below is equipped with connecting rod, connecting rod lower end detachably installed with galvanized combined sleeve, galvanized combined sleeve is composed of multiple hollow galvanized pipes of decreasing diameter;The utility model device can be realized by using the working principle of pushing oil cylinder, through the hollow galvanized pipe of pin taking device, the pin that needs to be taken out is placed in pin hole, pushing oil cylinder does retract action, pin is processed pin taking device, then the pin that needs to be taken out can be taken out through pin taking device, operating personnel also do not need to be taken fixed pin on pushing oil cylinder, solve the hidden danger of small space hammering operation, avoid the risk of personnel operation in the environment of narrow space of support pushing oil cylinder, to improve work efficiency, reduce risk.

The utility model relates to the technical field of blade polishing equipment, in particular to a pulping blade polishing device. Comprising a support, a grinding piece is arranged on the left side of the support, a longitudinal adjusting assembly is arranged on the support on one side of the grinding piece, and a transverse adjusting assembly is arranged on the right side of the support; the cutter table is connected with the longitudinal adjusting assembly in a sliding mode, and an extension plate connected with the transverse adjusting assembly in a sliding mode is arranged below the cutter table; the blade is driven to move back and forth through the longitudinal adjusting piece to achieve grinding operation, meanwhile, the blade can be quantitatively driven to move towards the grinding piece through the transverse adjusting piece, contact force is adjusted, grinding quality and grinding precision are guaranteed, and manual operation is replaced.

This utility model relates to a hydraulic system for automatic alarm and shutdown when encountering obstruction in coiled tubing, belonging to the field of coiled tubing operation technology. The technical solution is as follows: When the weight sensor on the injection head detects a sudden load change, and this load change reaches the initial set value, the weight sensor sends a pulse electrical signal to the solenoid directional valve. The main valve core of the solenoid directional valve reverses, and at this time, port 1 and port 2 of the solenoid directional valve are connected. Because port 2 of the solenoid directional valve is directly connected to the oil tank for unloading, the pressure difference acting on both sides of the three-position four-way servo valve is instantly relieved, and the three-position four-way servo valve returns to the neutral position. At this time, the output flow of the closed axial piston variable pump returns to 0, the speed of the injection head motor drops to 0, and the injection head motor automatically stops. This utility model does not require human intervention, avoiding operational losses caused by improper operation monitoring or failure to detect abnormal load fluctuations in a timely manner due to human negligence.
