Under the action of the filter screen 602, objects or other foreign matter can be prevented from entering the area around the turbine 601, thereby protecting the turbine 601.

[0031] See also Figure 1and Figure 2 An observation window 603 is connected to the box body 1. The observation window 603 is a transparent acrylic plate. By observing the observation window 603, workers can timely understand the activity status of the turbine 601.

[0032] See also Figure 2 The filter screen 602 is connected to a fixing plate 7, and a through groove is provided inside the fixing plate 7. By providing the fixing plate 7, the range of movement of the experimental object can be fixed.

[0033] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the movable plate 301 is connected to the carrying plate 4, the interior of the carrying plate 4 fits the outside of the proximity sensor body 2, the carrying plate 4 is connected to the connecting plate 401, the carrying plate 4 is rotatably connected to the arc plate 402, the connecting plate 401 is connected to the fixing block 403 by bolts, the fixing block 403 is connected to the arc plate 402, the carrying plate 4 is connected to the clamping plate 404, a slot 405 is opened inside the movable plate 301, the inside of the slot 405 fits the outside of the wire 201, and the carrying plate 4, the connecting plate 401, the arc plate 402, the fixing block 403 and the clamping plate 404 cooperate with each other to make the proximity sensor body 2 stably fixed inside the carrying plate 4 while facilitating the replacement of various types of proximity sensor bodies 2 by workers.

[0034] See also Figure 5 A plate 5 is connected to the top of the box body 1, and multiple groups of balls 501 are movably connected inside the plate 5. Grooves adapted to the balls 501 are opened inside the plate 5.

[0035] Working principle: First, a worker places the proximity sensor body 2 into the carrier plate 4, places the end of the wire 201 connected to the proximity sensor body 2 against the inner wall of the slot 405, pushes the front end of the proximity sensor body 2 into the card plate 404, and then rotates the curved plate 402 so that the inner wall of the curved plate 402 is in contact with the outer wall of the proximity sensor body 2, until the fixing block 403 enters the connecting plate 401, then the bolt can be rotated to fix the fixing block 403 inside the connecting plate 401, so that the proximity sensor body 2 is stably placed inside the carrier plate 4, and the end of the wire 201 away from the proximity sensor body 2 is inside the plate 5. As the wire 201 moves, its outer wall moves in contact with the outer wall of the ball 501, so that the ball 501 rolls in the groove opened inside the plate 5 that is compatible with the ball 501.

[0036] By starting the water pump, liquid enters the water pump and then flows back to the inside of the box 1 through the water pipe, so that the liquid inside the box 1 is kept in a circulating state, thereby preliminarily simulating the external liquid circulation environment. By driving motor 1, the screw 3 is driven to rotate, so that the movable plate 301 moves on the screw 3. While the movable plate 301 moves, it slides on the outer wall of the vertical rod 302. The movable plate 301 synchronously drives the supporting plate 4 to move, thereby driving the proximity sensor body 2 to rise and fall in the liquid, thereby recording the pressure data of the proximity sensor body 2 at different positions in the liquid. By hanging a rope on the fixed plate 7 and fixing different types of objects on the rope, the proximity sensor body 2 compares and detects objects in the same liquid and then records the data. When it is necessary to increase the circulation state of the liquid, the motor 2 can be turned on to make the rotating rod 6 drive the turbine 601 to rotate, thereby accelerating the flow of the liquid, so that the accuracy of the proximity sensor body 2 in detecting objects in liquids with different flow rates can be tested.
