DETAILED DESCRIPTION

[0022] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0023] Embodiment 1

[0024] In this embodiment, a scientific measurement device for geological disaster assessment is provided, such as Figure 1 As shown, it includes a pair of legs 1, and a base rod 2 is installed between the two legs 1. The lower ends of the legs 1 are folded outwards, so that they can be placed on the ground more stably during measurement. Measuring rods 3 are symmetrically installed on the base rods 2, and the measuring rods 3 can slide controllably on the base rods 2. The measuring rods 3 can slide left and right on the base rods 2, and can also slide up and down. A support block 4 is fixedly connected to the lower end of the outer side surface of the measuring rod 3. By controlling the position of the measuring rod 3, the support block 4 on it can fit the side wall of the geological fracture currently measured. At this time, the distance between the outer sides of the two measuring rods 3 plus the length of the support block 4 (the side of the two measuring rods 3 away from each other is the outer side surface) can determine the width of the geological fracture. The setting of the support block 4 can avoid the problem that the unevenness inside the fracture affects the measurement of the measuring rod 3;

[0025] By adjusting the height of the measuring rod 3, the width of the geological fracture at different positions can be measured, so that the staff can make the evaluation result more accurate.

[0026] like Figure 2 As shown, a through groove 7 matched with the measuring rod 3 is provided on the base rod 2. The measuring rod 3 passes through the through groove 7 and is slidably connected to the base rod 2 through a limiting sleeve 8 sleeved thereon. The limiting sleeve 8 is slidably connected to the upper side surface of the base rod 2. The lower end of the measuring rod 3 passes through the through groove 7 and extends to the bottom of the base rod 2. An extrusion bolt is meshedly connected to the limiting sleeve 8. By rotating the extrusion bolt on the limiting sleeve 8 clockwise, the extrusion bolt can apply a tightening force to the corresponding measuring rod 3, thereby keeping the upper and lower positions of the measuring rod 3 fixed.

[0027] The outer side of the limiting sleeve 8 is connected with a slide plate 11 through a spring 10. One end of the spring 10 is fixedly connected to the slide plate 11, and the other end is fixedly connected to the limiting sleeve 8. The slide plate 11 is slidably connected to the base rod 2. When measuring, the measuring rod 3 is pulled by the slide plate 11 to make the support block 4 and the side wall of the measured geological crack fit each other, and the spring 10 is kept in a stretched state. At this time, under the tension of the spring 10, the support block 4 will fit tightly with the geological crack, so that the measured data can be more accurate, and the slide plate 11 is also meshed with an extrusion bolt. By rotating the extrusion bolt on the slide plate 11 clockwise, the corresponding extrusion bolt can apply a tightening force to the base rod 2, so that the position of the slide plate 11 on the base rod 2 can be kept fixed, which is convenient for the staff to operate.

[0028] Embodiment 2

[0029] like Figure 5 As shown, the outer side surface of the upper end of the measuring rod 3 is fixedly connected to a fixed block 5, and the outer side surface of the fixed block 5 and the outer end point of the supporting block 4 are in the same vertical plane. When the staff judges the width of the geological fracture currently being measured, they can directly measure the distance between the two fixed blocks 5.

[0030] Embodiment 3

[0031] like Figure 3 As shown, a slot 13 is provided on the inner side surface of the leg 1, and a controllable extension rod 14 is installed inside the slot 13. A through hole matched with the rod 14 is provided on the lower end groove wall of the slot 13, and the rod 14 can pass through the through hole and be inserted into the ground, so that the leg 1 can be better maintained stable on the ground. A fixing plate 15 is fixedly connected to the upper end of the rod 14, and the fixing plate 15 is slidably connected to the inside of the slot 13, and the fixing plate 15 is connected to a pedal 17 located on the outside of the leg 1 through a connecting shaft 16. The connecting shaft 16 extends to the outside of the leg 1 through the barrel groove provided on the leg 1, and the height of the fixing plate 15 inside the slot 13 can be controlled by the pedal 17, thereby controlling the position of the rod 14 inside the slot 13.

[0032] Both ends of the fixed plate 15 are provided with retractable blocks 18, and the groove wall of the empty groove 13 is provided with a groove 19 adapted to the block 18. When the block 18 extends from the inside of the fixed plate 15, it will engage with the groove 19, so that the position of the fixed plate 15 inside the empty groove 13 can be kept fixed. When the block 18 is retracted into the fixed plate 15, the fixed plate 15 can slide up and down inside the empty groove 13. The block 18 is controlled to retract and retract by the pedal 17. The pedal 17 can control whether the block 18 is retracted into the fixed plate 15, thereby controlling whether the fixed plate 15 can slide inside the empty groove 13.

[0033] like Figure 4 As shown, a cavity 20 is opened inside the fixing plate 15, and the block 18 passes through the fixing plate 15 and extends to the inside of the cavity 20 and is connected to the side wall of the cavity 20 through the first spring sheet 6. The first spring sheet 6 has a tendency to pull the block 18 into the cavity 20. An extrusion block 9 is provided between the two blocks 18. The inner side surface of the block 18 is an inclined surface. The extrusion block 9 is provided with an inclined surface corresponding to the block 18. The inclined surface of the extrusion block 9 fits the inclined surface of the block 18. The extrusion block 9 is connected to the connecting shaft 16, and the extrusion block 9 is connected to the connecting shaft 16. A second spring piece 12 is connected between the side walls of the cavity 20. The second spring piece 12 has an elastic force that presses the extrusion block 9 against the inside of the cavity 20. Under the elastic force of the second spring piece 12, the extrusion block 9 applies a pressing force to the clamping block 18, so that the clamping block 18 overcomes the elastic force of the first spring piece 6 and moves toward the outside of the cavity 20, thereby stably engaging with the clamping groove 19. Pulling the pedal 17 can pull the extrusion block 9 through the connecting shaft 16, so that the clamping block 18 retracts into the cavity. At this time, the fixing plate 15 can slide inside the slot 13.

[0034] The outer side of the pedal 17 is folded upwards, which makes it convenient for the staff to pull the connecting shaft 16 through the pedal 17 .

[0035] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
