[0002] Retaining walls are structures that support roadbed fill or hillside soil and prevent fill or soil from deforming and becoming unstable. Tailings filling retaining walls are formed by using full-grade tailings that have not been graded and desludged as filling aggregates, mixed evenly with a certain proportion of cementing materials and water, and then filled.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] For example, see Figure 1-Figure 5 A tailings filling retaining wall deformation displacement monitoring device includes a first anchor rod 100 and a shell 200. The first anchor rod 100 is buried in the retaining wall, the shell 200 is installed on the ground, a displacement sensor 300 and a differential lever mechanism 400 are arranged on the shell 200, and a pull rod 310 is slidably arranged on the displacement sensor 300.

[0034] The differential lever mechanism 400 includes a second anchor rod 410 slidably arranged on the housing 200, a first rotating rod 420 rotatably arranged on the housing 200, a first lever 430 is arranged on the first rotating rod 420, the left end of the first lever 430 is connected to the second anchor rod 410, the right end of the first lever 430 is connected to the pull rod 310, and the distance between the first rotating rod 420 and the left end of the first lever 430 is smaller than the distance between the first rotating rod 420 and the right end of the first lever 430.

[0035] It also includes a temperature difference compensation mechanism 500, which includes a third slide groove 510 opened on the first anchor rod 100, and the second anchor rod 410 is slidably connected in the third slide groove 510. Two metal plates 520 are arranged on the second anchor rod 410, and the thermal expansion coefficient of the metal plate 520 located on the left is greater than that of the metal plate 520 located on the right.

[0036] A first connecting seat 440 is provided on the second anchor rod 410, a first sliding groove 450 is opened on the first connecting seat 440, a second connecting seat 460 is provided on the pull rod 310, a second sliding groove 470 is opened on the second connecting seat 460, and first connecting shafts 480 are provided at both ends of the first lever 430, and the two first connecting shafts 480 are respectively slidably connected in the first sliding groove 450 and the second sliding groove 470.

[0037] The differential lever mechanism 400 is used to enable the first anchor rod 100 to drive the pull rod 310 to move with a transmission ratio greater than one, and the temperature difference compensation mechanism 500 is used to offset the deformation of the first anchor rod 100 caused by temperature change.

[0038] In this embodiment: Figure 7 As shown, the first anchor rod 100 can be deeply buried in the tailings filling retaining wall by drilling or other methods. The first anchor rod 100 will be displaced as the retaining wall is deformed. For example, when the retaining wall is set to deform and displace to the right, the first anchor rod 100 will be displaced to the right. The shell 200 is supported on the ground by a plurality of support legs 240. The shell 200 is composed of three sections, which are the first mounting seat 210, the second mounting seat 220 and the third mounting seat 230 from left to right. The displacement sensor 300 installed in the first mounting seat 210 can be a pull rod type displacement sensor. The measurement module inside the displacement sensor 300 will convert an electrical signal according to the distance of displacement of the pull rod 310 in the up and down directions, which can be connected to the remote monitoring system for digital display.

[0039] In order to improve the sensitivity of the displacement sensor 300, the displacement of the first anchor rod 100 needs to be proportionally amplified. Specifically, when the first anchor rod 100 moves to the right, the second anchor rod 410 and the first connecting seat 440 move to the right synchronously. The first connecting seat 440 moves to the right, causing the first lever 430 to rotate counterclockwise based on the first rotating rod 420. The first connecting shaft 480 on the left side of the first lever 430 slides down along the first sliding groove 450. At the same time, the first connecting shaft 480 on the right side of the first lever 430 slides to the left along the second sliding groove 470, and drives the pull rod 310 to move up. Since the first lever 430 is a differential lever, the first rotating rod 420 is close to the left end of the first lever 430. Therefore, after the first lever 430 amplifies the rated multiple, the displacement of the pull rod 310 is measured by the displacement sensor 300, and then converted according to the fixed multiple between the displacement of the first anchor rod 100 and the displacement of the pull rod 310.

[0040] In addition, it is also considered that the first anchor rod 100 is usually made of metal and is more solid, but it will be affected by the thermal expansion and contraction of the wall. For example, when the wall is at a high temperature, the first anchor rod 100 will expand due to the heat, which will produce a false displacement to the right, and it is not that the wall is actually deformed to the right. At this time, the temperature difference compensation mechanism 500 can offset this error value.

[0041] Specifically, the second anchor rod 410 and the first anchor rod 100 are not fixedly connected, but connected by a bimetallic plate composed of two metal plates 520. The bimetallic plate is made of two metals with significantly different thermal expansion coefficients, such as copper with high CTE and steel with low CTE, which are compounded by rolling or welding. When the temperature rises, the metal plate 520 with a high thermal expansion coefficient on the left side forces the bimetallic plate to bend to the right until it is against the inner wall of the first anchor rod 100 and then bends further, pulling the second anchor rod 410 closer to the first anchor rod 100, that is, the second anchor rod 410 moves to the left by a certain distance relative to the first anchor rod 100, thereby offsetting the false displacement to the right caused by the thermal expansion of the first anchor rod 100.

[0042] Similarly, when the first anchor rod 100 contracts due to cooling, a false displacement to the left is generated. At this time, the bimetal plate bends to the left, causing the second anchor rod 410 to move to the right.

[0043] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 1-Figure 5 An adjusting rod 530 is slidably provided on the second anchor rod 410 , and both metal plates 520 are connected to the adjusting rod 530 . A first knob 540 is threadedly installed on the second anchor rod 410 , and the adjusting rod 530 is rotatably connected to the first knob 540 .

[0044] In this embodiment: In order to adapt to different working environments, an adjustable working state is also set for the bimetallic plate. By turning the first knob 540 forward and backward, the adjustment rod 530 can be driven to move left and right. When the adjustment rod 530 moves to the left, the degree of bending of the bimetallic plate to the left increases. A higher ambient temperature is required to make the bimetallic plate bend to the right and press against the inner wall of the first anchor rod 100 and further pull the second anchor rod 410 relatively to the left. Similarly, when the adjustment rod 530 moves to the right, only a smaller increase in ambient temperature is required to pull the second anchor rod 410 relatively to the left.

[0045] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 11 , and also includes a first-level alarm mechanism 600 and a first delayed transmission mechanism 700. The first-level alarm mechanism 600 includes a first sound and light alarm 610 arranged on the shell 200, and the first sound and light alarm 610 is provided with a first button 620. A first trigger rod 630 is slidably arranged in the shell 200.

[0046] The first delayed transmission mechanism 700 is used to realize transmission between the pull rod 310 and the first trigger rod 630 , and trigger the first button 620 through the displacement of the first trigger rod 630 .

[0047] The first delayed transmission mechanism 700 includes a third connecting seat 710 arranged on the pull rod 310 and a fourth connecting seat 720 arranged on the first trigger rod 630. A second rotating rod 730 is rotatably arranged in the shell 200, and a second lever 740 is arranged on the second rotating rod 730. The third connecting seat 710 and the fourth connecting seat 720 are respectively connected to the two ends of the second lever 740.

[0048] The first delay transmission mechanism 700 also includes a first connecting rod 750, and second connecting shafts 760 are provided at both ends of the first connecting rod 750. A fourth sliding groove 770 is opened on the left side of the second lever 740. The second connecting shaft 760 on the left side is rotatably connected to the third connecting seat 710, and the second connecting shaft 760 on the right side is slidably connected in the fourth sliding groove 770.

[0049] A fifth sliding groove 780 is defined on the fourth connecting seat 720 . A third connecting shaft 790 is disposed on the right side of the second lever 740 . The third connecting shaft 790 is slidably connected in the fifth sliding groove 780 .

[0050] It also includes a secondary alarm mechanism 800 and a second delayed transmission mechanism 900. The secondary alarm mechanism 800 includes a second sound and light alarm 810 arranged on the shell 200. The second sound and light alarm 810 is provided with a second button 820. A second trigger rod 830 is slidably arranged in the shell 200.

[0051] The second delayed transmission mechanism 900 is used to realize the transmission between the first trigger rod 630 and the second trigger rod 830 , and trigger the second button 820 through the displacement of the second trigger rod 830 .

[0052] The structure of the second delay transmission mechanism 900 is consistent with that of the first delay transmission mechanism 700. The second delay transmission mechanism 900 includes a fifth connecting seat 910 arranged on the second trigger rod 830 and a sixth connecting seat 920 arranged on the first trigger rod 630. A third rotating rod 930 is rotatably arranged in the shell 200, and a third lever 940 is arranged on the third rotating rod 930. The fifth connecting seat 910 and the sixth connecting seat 920 are respectively connected to the two ends of the third lever 940.

[0053] The second delay transmission mechanism 900 also includes a second connecting rod 950, and fourth connecting shafts 960 are provided at both ends of the second connecting rod 950. A sixth sliding groove 970 is opened on the right side of the third lever 940. The fourth connecting shaft 960 on the right side is rotatably connected to the fifth connecting seat 910, and the fourth connecting shaft 960 on the left side is slidably connected in the sixth sliding groove 970.

[0054] A seventh sliding groove 980 is defined on the sixth connecting seat 920 , and a fifth connecting shaft 990 is disposed on the left side of the third lever 940 . The fifth connecting shaft 990 is slidably connected in the seventh sliding groove 980 .

[0055] In this embodiment: an active alarm function is also designed for the device. When the measured displacement of the retaining wall is less than a certain level, neither the first-level alarm mechanism 600 nor the second-level alarm mechanism 800 will be triggered. When the displacement reaches the range of the first-level alarm mechanism 600, the first-level alarm mechanism 600 triggers the sound and light alarm. When the displacement reaches the range of the second-level alarm mechanism 800, both the first-level alarm mechanism 600 and the second-level alarm mechanism 800 trigger the sound and light alarm.

[0056] Specifically, when the first trigger rod 630 moves downward and abuts against the first button 620, the first sound and light alarm 610 is triggered to operate, and when the second trigger rod 830 moves upward and abuts against the second button 820, the second sound and light alarm 810 is triggered to operate. Due to the requirement of hierarchical triggering, the pull rod 310, the first trigger rod 630 and the second trigger rod 830 need to be delayed in sequence.

[0057] refer to Figure 7-10 First, when the displacement of the first anchor rod 100 is in the first level range, Figure 8As shown, the pull rod 310 and the third connecting seat 710 move upward, and at this time, the second rotating rod 730 is supported by the elastic force of the spring 1010 to maintain the normal horizontal position of the second lever 740. When the pull rod 310 and the third connecting seat 710 start to move upward, they will not immediately drive the second lever 740 to rotate. In the first level range, the third connecting seat 710 moves upward to drive the first connecting rod 750 to rotate clockwise based on the second connecting shaft 760 on the left. At this time, the second connecting shaft 760 on the right moves left along the fourth sliding groove 770, and will not drive the second lever 740 to rotate. That is, the first trigger rod 630 and the second trigger rod 830 do not move, and the first-level alarm mechanism 600 and the second-level alarm mechanism 800 do not operate.

[0058] When the displacement of the first anchor rod 100 is in the second level range, Fig. 9 As shown, the third connection seat 710 moves upward to drive the first connection rod 750 to continue to rotate clockwise based on the second connection shaft 760 on the left side, until the second connection shaft 760 on the right side moves to the leftmost side of the fourth slide groove 770, and the pull rod 310 and the third connection seat 710 continue to move upward to drive the second lever 740 to rotate clockwise based on the second rotating rod 730. At this time, the third connection shaft 790 will move left along the fifth slide groove 780, and push the fifth slide groove 780 and the first trigger rod 630 to move downward. The first trigger rod 630 and the sixth connection seat 920 move downward to make the third lever 940 rotate counterclockwise based on the third rotating rod 930. At this time, the second connection rod 950 rotates clockwise based on the fourth connection shaft 960 on the right side, and the fourth connection shaft 960 on the left side moves right along the sixth slide groove 970, which will not drive the fifth connection seat 910 and the second trigger rod 830 to move downward. That is, the first trigger rod 630 moves downward, the second trigger rod 830 does not move, the first-level alarm mechanism 600 operates, and the second-level alarm mechanism 800 does not operate.

[0059] When the displacement of the first anchor rod 100 is in the third level range, Fig.10 As shown, the second connecting rod 950 continues to rotate clockwise based on the fourth connecting shaft 960 on the right side until the fourth connecting shaft 960 on the left side reaches the rightmost side of the sixth sliding groove 970, and the third lever 940 continues to rotate counterclockwise based on the third rotating rod 930, driving the fifth connecting seat 910 and the second trigger rod 830 to move upward. At this time, both the primary alarm mechanism 600 and the secondary alarm mechanism 800 are in operation.

[0064] A third knob 1140 is threadedly mounted on the housing 200 , and the third knob 1140 is connected to the second sliding seat 1120 .

[0065] In this embodiment: In order to prevent accidental resetting, the first locking mechanism 1000 is added to the second rotating rod 730 and the third rotating rod 930. The tooth directions of the ratchet 1030 and the pawl 1040 in the two first locking mechanisms 1000 are opposite. Taking the first locking mechanism 1000 located on the right side as an example, when the third rotating rod 930 rotates counterclockwise, the ratchet 1030 and the third rotating rod 930 rotate counterclockwise together. At this time, the directions of the teeth of the ratchet 1030 and the pawl 1040 are clockwise, and the ratchet 1030 can rotate counterclockwise. The spring sheet 1050 presses the pawl 1040 toward the ratchet 1030, and the ratchet 1030 drives the pawl 1040 to swing continuously.

[0066] When the first anchor rod 100 is displaced to the left and reset for some reason, the third rotating rod 930 has a tendency to rotate clockwise and reset due to the reset elastic force of the clockwork spring 1010, but the ratchet 1030 is stuck by the pawl 1040 and cannot rotate clockwise. Therefore, the first trigger rod 630 and the third rotating rod 930 cannot be reset in the reverse direction. The first sound and light alarm 610 and the second sound and light alarm 810 continue to operate and can only be manually released by the staff. The manual release method is to turn the second knob 1060 to move the first slide 1020 and the pawl 1040 backward, so that the ratchet 1030 and the pawl 1040 are disengaged. At this time, the first trigger rod 630 or the third rotating rod 930 will be reset under the elastic force of the clockwork spring 1010.

[0067] At this time, when the deformation displacement of the first anchor rod 100 reaches the third level range, the danger is relatively high. In addition to waiting for the staff to receive the alarm and handle it, the second locking mechanism 1100 also plays a certain role in resisting further rightward movement of the wall.

[0068] Specifically, when the stop block 1110 touches the inner wall of the stop slot 1130 as the third rotating rod 930 rotates counterclockwise, the third rotating rod 930 can no longer rotate counterclockwise, giving the first anchor rod 100 a leftward resistance in the opposite direction. The upper limit of triggering the first anchor rod 100 to move rightward can also be adjusted, and the position of the stop slot 1130 can be changed by turning the third knob 1140 to drive the second slide seat 1120 to rotate.

[0069] In addition, Fig.11 As shown, when the second rotating rod 730 is locked and cannot be rotated counterclockwise to reset, if the first anchor rod 100 moves to the left, causing the pull rod 310 and the third connecting seat 710 to descend, they will not be hindered. At this time, the second connecting shaft 760 on the right side of the first connecting rod 750 will slide right along the fourth sliding groove 770.

[0070] Embodiment 5: This embodiment is an improvement made on the basis of Embodiment 4. For details, please refer to Figure 1-Figure 4 The shell 200 includes a first mounting seat 210, a second mounting seat 220 and a third mounting seat 230, the displacement sensor 300 and the differential lever mechanism 400 are arranged on the first mounting seat 210, the first-level alarm mechanism 600 and the first delay transmission mechanism 700 are arranged on the second mounting seat 220, and the second-level alarm mechanism 800 and the second delay transmission mechanism 900 are arranged on the third mounting seat 230.

[0071] The second mounting seat 220 is slidably connected to the first mounting seat 210, and the third mounting seat 230 is slidably connected to the second mounting seat 220. Support legs 240 are provided on the first mounting seat 210 and the second mounting seat 220. A fourth knob 250 is threadedly installed on the first mounting seat 210, and the fourth knob 250 is rotatably connected to the second mounting seat 220. A fifth knob 260 is threadedly installed on the second mounting seat 220, and the fifth knob 260 is rotatably connected to the third mounting seat 230.

[0072] In this embodiment, the three-level displacement range of the first anchor rod 100 can also be adjusted. By turning the fourth knob 250, the second mounting seat 220 can be driven to move left or right relative to the first mounting seat 210, thereby adjusting the second connecting shaft 760 on the right side of the first connecting rod 750 to be in the initial position in the fourth sliding groove 770. By turning the fifth knob 260, the fourth connecting shaft 960 on the left side of the second connecting rod 950 can be adjusted to be in the initial position in the sixth sliding groove 970.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
