[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a portable testing device for mine ecological assessment, including a storage box 1, a winding reel 2 on the inner side of the storage box 1, a measuring tape 3 on the outer side of the winding reel 2, a cleaning channel 4 on the right side of the lower end of the storage box 1, a cleaning ring 41 at the right end of the cleaning channel 4, a positioning block 5 at the end of the measuring tape 3, a positioning pin 6 at the lower end of the positioning block 5, a threaded sleeve 7 on the surface of the positioning block 5, a threaded pin 8 on the inner side of the threaded sleeve 7, a turntable 9 on the front side of the storage box 1, a friction block 10 on the rear side of the turntable 9, a friction plate 11 on the surface of the storage box 1, a lead screw 12 at the front end of the friction block 10, a threaded hole 13 on the left side of the lower end of the storage box 1, and an insertion hole 14 on the side of the threaded hole 13.

[0024] Please see Figures 1-3 In this embodiment, one end of the measuring tape 3 is fixedly connected to the winding reel 2, and the other end of the measuring tape 3 extends to the outside of the storage box 1 through the cleaning channel 4. The positioning block 5 is fixedly connected to the end of the measuring tape 3. The cleaning ring 41 is detachably connected to the outer side of the right end of the cleaning channel 4. The inner side of the cleaning ring 41 is provided with flexible bristles. The positioning pin 6 is fixedly connected to the lower end of the positioning block 5. The threaded sleeve 7 is arranged vertically through the positioning block 5. The threaded pin 8 is threadedly connected to the inner side of the threaded sleeve 7. The upper end of the threaded pin 8 is fixedly installed with a rotating handle 81. By rotating the rotating handle 81, the threaded pin 8 can be lifted off the ground, and the positioning pin 6 can be pulled out.

[0025] Please see Figures 2-5 In this embodiment, a handle is fixedly installed on the upper end of the storage box 1. The front and rear ends of the winding reel 2 are rotatably connected to the inner side of the storage box 1. The front end of the winding reel 2 extends to the outer side of the storage box 1 and is fixedly connected to the turntable 9. A crank handle 91 is fixedly installed on the front side of the turntable 9. An annular groove is formed on the surface of the storage box 1. The friction plate 11 is fixedly connected to the inner side of the annular groove. The friction block 10 is adapted to the inner side of the annular groove. The rear end of the lead screw 12 is fixedly connected to the friction block 10. The front end of the lead screw 12 extends to the outer side of the storage box 1. A knob 121 is fixedly installed on the front side of the turntable 9. The lead screw 12 is threadedly connected to the turntable 9. By rotating the turntable 9 with the crank handle 91, the winding reel 2 can be rotated to wind up the tape measure 3. Then, by rotating the knob 121, the lead screw 12 drives the friction block 10 to fit tightly with the friction plate 11, thereby fixing the turntable 9 and the winding reel 2. During the winding process of the tape measure 3, the bristles on the inner side of the cleaning ring 41 clean the impurities on the surface of the tape measure 3 to prevent impurities from being rolled into the storage box 1 and causing wear on the tape measure 3.

[0026] Please see Figures 1-4In this embodiment, the inner sides of the positioning pin 6 and the insertion hole 14 are adapted to each other, and the inner sides of the threaded pin 8 and the threaded hole 13 are adapted to each other. By inserting the positioning pin 6 into the insertion hole 14 and then rotating the handle 81 to drive the threaded pin 8 to be threadedly connected to the threaded hole 13, the positioning block 5 and the end of the measuring tape 3 can be quickly stored and fixed, which is convenient and fast.

[0027] During operation, place the positioning block 5 in a suitable position on the ground. Pressing the positioning block 5 causes the positioning pin 6 to insert into the ground. Rotating the handle 81 causes the threaded pin 8 to rotate, drilling it into the ground and fixing the positioning block 5. At this time, rotating the knob 121 causes the lead screw 12 to rotate, controlling the friction block 10 to disengage from the friction plate 11, releasing the fixation on the turntable 9. This allows the storage box 1 to be pulled away from the positioning block 5, causing the winding reel 2 to rotate and the measuring tape 3 to extend to a suitable length for measurement. After the evaluation and testing are completed, rotating the handle 81 in the opposite direction causes the threaded pin 8 to detach from the ground, allowing the positioning pin 6 to be pulled out. Rotating the turntable 9 by cranking the handle 91 will drive the winding reel 2 to rotate and wind up the measuring tape 3. Then, rotating the knob 121 will cause the lead screw 12 to drive the friction block 10 and the friction plate 11 to fit tightly together, thereby fixing the turntable 9 and the winding reel 2. During the winding process of the measuring tape 3, the bristles on the inner side of the cleaning ring 41 will clean the impurities on the surface of the measuring tape 3 to prevent impurities from being rolled into the storage box 1 and causing wear on the measuring tape 3. By inserting the positioning pin 6 into the insertion hole 14 and then rotating the handle 81 to drive the threaded pin 8 to connect with the threaded hole 13, the positioning block 5 and the end of the measuring tape 3 can be quickly and conveniently stored and fixed.

[0028] Through the above steps, by rotating the handle 81 to lift the threaded nail 8 off the ground, the positioning nail 6 can be pulled out. By rotating the turntable 9, the winding reel 2 can be wound up to reel the tape measure 3. The lead screw 12 drives the friction block 10 and the friction plate 11 to fit tightly together, thereby fixing the turntable 9 and the winding reel 2. During the winding process of the tape measure 3, the bristles on the inner side of the cleaning ring 41 clean the impurities on the surface of the tape measure 3, preventing impurities from being rolled into the storage box 1 and causing wear on the tape measure 3. By inserting the positioning nail 6 into the insertion hole 14, and then rotating the handle 81 to drive the threaded nail 8 to connect with the threaded hole 13, the positioning block 5 and the end of the tape measure 3 can be quickly stored and fixed. This solves the problems of time-consuming and labor-intensive storage of the tape measure in the portable testing equipment for mine ecological assessment, which is inefficient and the tape measure surface is prone to adhering to impurities, causing damage to the tape measure and affecting the service life of the equipment.
