[0021] Among them, the particle monitor 15 is the i CountPD laser particle detector of Parker Company, which is designed to continuously monitor the contamination and solid particle level in the hydraulic oil system.

[0022] In this embodiment, specifically, the mobile seat 1 is rectangular, a control cabinet 2 is fixed to one side of the short side of the top of the mobile seat 1, a flippable rectangular protective cover 9 is hinged to the other side of the short side of the top of the mobile seat 1, an opening for accommodating the control cabinet 2 is opened on one side of the protective cover 9, and guardrails 8 are fixed to both sides of the long side of the top of the mobile seat 1;

[0024] In this embodiment, specifically, the oil tank 3 and the valve block 6 are fixed to the top of the moving seat 1 close to the long side, and the filter 7 is fixed to one side of the valve block 6 .

[0025] In this embodiment, specifically, a hydraulic pump 5 and a motor 4 for driving the hydraulic pump 5 are fixed on the top of the mobile seat 1, the oil tank 3, the hydraulic pump 5, the filter 7 and the valve block 6 are connected in sequence, and the output end of the valve block 6 is also connected with a high-pressure delivery pipe 10;

[0026] The oil tank 3 is connected to the hydraulic pump 5 through a pipe body, the hydraulic pump 5 is connected to the filter 7 through a pipe body, the filter 7 is connected to the valve block 6 through a pipe body, and the valve block 6 is connected to a high-pressure delivery pipe 10 to output hydraulic oil to the aircraft.

[0027] In this embodiment, specifically, a flow meter 11 and a pressure gauge 12 penetrating into the internal passage are fixed on the top of the valve block 6;

[0028] The probes of the flow meter 11 and the pressure meter 12 seal the passage that penetrates into the interior of the valve block 6 , that is, the output oil passage, and detect the output flow and pressure.

[0029] In this embodiment, specifically, the mounting bracket 14 is fixed to the top of the valve block 6 by screws, the limiting groove 17 is opened through the end of the mounting bracket 14, and the width is consistent with the outer diameter of the detection tube 16, the bottom of the limiting groove 17 is semicircular, and a slot 18 with a height higher than the detection tube 16 is opened on one side, the extrusion block 19 is embedded in the slot 18, and the extrusion block 19 is opened on the side facing the detection tube 16. The arc groove 23 that matches the curvature of the detection tube 16 is opened, and the inner surface of the slot 18 is opened through a threaded hole 20, and the threaded hole 20 is threadedly connected with a threaded rod 21, one end of the threaded rod 21 is rotatably connected to the inner surface of the extrusion block 19, and a tightening knob 22 is fixed to the outer end;

[0030] Among them, the detection tube 16 is a port provided by the particle monitor 15. The particle monitor 15 can be tightened by tightening the detection tubes 16 at both ends of the particle monitor 15. After installation, the two detection tubes 16 can be connected to the circulating oil port of the valve block 6 using a hose. When the oil passes through the inside of the valve block 6, it will enter a hose and the detection tube 16 to the particle monitor 15 for monitoring, and then return to the oil circuit of the valve block 6 from another detection tube 16 and hose.

[0031] Working principle: When delivering hydraulic oil to an aircraft, the high-pressure delivery pipe 10 is connected to the valve block 6 and the hydraulic system of the aircraft respectively, and the motor 4 drives the hydraulic pump 5 to deliver the hydraulic oil in the oil tank 3 to the filter 7 for filtration.

Since the arc groove 23 of the extrusion block 19 matches the curvature of one side of the detection tube 16, the detection tube 16 cannot move up at this time. In addition, the body of the particle monitor 15 is located between the U-shaped mounting frames 14 and cannot move left and right, which completes its fixation. Finally, two hoses are used to connect the two detection tubes 16 with the two circulating oil ports of the valve block 6. When disassembling, remove the hoses, reverse the knob to drive the extrusion block 19 back into the slot 18, and the particle monitor 15 can be lifted.
