DETAILED DESCRIPTION

[0027] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1: A ground subsidence dynamic monitoring device, such as Figure 1-Figure 11 As shown, it includes a fixed bottom plate 1, a sedimentation cylinder 101, a sedimentation rod 102, a fixed connecting block 103, a fixed guide rod 104, a sedimentation frame 2, a limiting assembly, an expansion mechanism and an underground settlement indicating mechanism. The fixed bottom plate 1 is fixedly connected to the sedimentation cylinder 101, the sedimentation cylinder 101 is hollow, the sedimentation rod 102 is slidably connected in the sedimentation cylinder 101, the upper section of the sedimentation rod 102 is provided with a thread, the sedimentation rod 102 is fixedly connected to the fixed connecting block 103, and a regular hexagonal groove is provided on the top surface of the fixed connecting block 103, so that the position of the sedimentation rod 102 in the sedimentation cylinder 101 can be adjusted by the fixed connecting block 103, the fixed guide rod 104 is fixedly connected to the fixed bottom plate 1, the fixed guide rod 104 is slidably connected to the sedimentation frame 2, the limiting assembly is installed in the sedimentation frame 2, the limiting assembly is used to limit the sedimentation rod 102, the expansion mechanism is arranged in the sedimentation rod 102, and the underground settlement indicating mechanism is installed on the fixed bottom plate 1.

[0029] When using this device, first open a circular through hole in the concrete floor, place the device against the wall and align the sedimentation cylinder 101 with the circular through hole on the ground, fix the bottom plate 1 to fit with the concrete floor, and fix the sedimentation frame 2 to the wall. At this time, the sedimentation rod 102 is limited by the limit assembly, and the sedimentation rod 102 can only rotate and descend, and will not slide downward due to gravity. After the device is fixed, use a tool to drive the sedimentation rod 102 to rotate through the fixed connecting block 103, so that the sedimentation rod 102 rotates and descends into the ground. When the sedimentation rod 102 descends, the deployment mechanism will descend accordingly. When the sedimentation rod 102 descends to a certain height, the deployment mechanism will contact the limit assembly. As the sedimentation rod 102 continues to descend The limit assembly will prevent the deployment mechanism from descending with the settlement rod 102, and the deployment mechanism can be extended outside the settlement rod 102, and then the settlement rod 102 continues to be rotated, so that the part of the deployment mechanism extended outside the settlement rod 102 can be transferred into the soil, and at the same time, the deployment mechanism can also release the restriction of the limit assembly on the settlement rod 102, and the deployment mechanism can increase the contact area between the settlement rod 102 and the underground soil. The settlement rod 102 is affected by the friction force of the settlement cylinder 101, so that the settlement rod 102 can be synchronously descended with the underground settling soil, and when the deployment mechanism releases the restriction of the limit assembly on the settlement rod 102, the settlement rod 102 will be driven to descend when the underground soil settles, and the underground settlement indication mechanism will give a prompt.

[0030] Embodiment 2: Based on embodiment 1, Figure 5 and Figure 6 As shown, the limiting assembly includes a sliding rod 204, an arc plate 2041, a connecting spring 205, an L-shaped block 206 and a supporting spring 207. The sliding rod 204 is symmetrically slidably connected in the sedimentation frame 2. An arc plate 2041 is fixedly connected to each sliding rod 204. A thread is provided in the arc plate 2041. When the two arc plates 2041 are aligned, a circular sleeve can be formed, and the threads in the two arc plates 2041 match. The threads on the two arc plates 2041 match the threads on the sedimentation rod 102. When the two arc plates 2041 are in contact, the sedimentation rod 102 can be prevented from falling freely. A connecting spring 205 is provided between the sliding rod 204 and the sedimentation frame 2. An L-shaped block 206 is slidably connected in the sliding rod 204. A supporting spring 207 is provided between the L-shaped block 206 and the sliding rod 204. The supporting spring 207 can push the L-shaped block 206 out of the sliding rod 204.

[0031] In the initial state, the arc plates 2041 on the two sliding rods 204 are in contact, and the threads in the two arc plates 2041 match the sinking rod 102. At this time, the L-shaped block 206 is pushed upward by the support spring 207, and the L-shaped block 206 is on the inner side of the sinking frame 2 to limit the position of the sliding rod 204. When the fixed connecting block 103 is rotated, the sinking rod 102 rotates accordingly and will descend along the arc plate 2041. When the restriction on the sinking rod 102 is released, it is only necessary to push the L-shaped block 206 to slide into the sliding rod 204, so that the L-shaped block 206 is out of contact with the sinking frame 2. Under the push of the connecting spring 205, the sliding rod 204 can move away from each other along the sinking frame 2, and the two arc plates 2041 move accordingly and are out of contact with the sinking rod 102.

[0032] like Figure 2-Figure 5 As shown, the unfolding mechanism includes a sliding rod 1021, a rotating block 1022, a pull rope 1023 and an unlocking assembly. The sliding rod 1021 is slidably connected inside the settlement rod 102, the fixed connection block 103 passes through the sliding rod 1021 and is slidably connected thereto, the rotating block 1022 is rotatably connected inside the settlement rod 102, the sliding rod 1021 and the rotating block 1022 are connected by the pull rope 1023, the sliding rod 1021 can pull the rotating block 1022 to unfold outside the settlement rod 102 through the pull rope 1023, the unlocking assembly is installed on the settlement frame 2, and the unlocking assembly is used to contact the limit assembly on the settlement rod 102.

[0033] When the sinking rod 102 descends, the sliding rod 1021, the rotating block 1022, the pull rope 1023 and the unlocking assembly descend accordingly. When the unlocking assembly contacts the L-shaped block 206, as the sinking rod 102 continues to descend, due to the large elastic force of the support spring 207, the unlocking assembly and the sliding rod 1021 are blocked and no longer descend with the sinking rod 102. As the sinking rod 102 continues to descend, the sliding rod 1021 slides inside the sinking rod 102. At the same time, the sliding rod 1021 pulls the rotating block 1022 to rotate and unfold around the sinking rod 102 through the pull rope 1023. When the top surface of the sliding rod 1021 contacts the fixed connecting block 103, the sinking rod 102 continues to be rotated to make it descend, and the sliding rod 1021 will drive the unlocking assembly to descend and push the L-shaped block 206 into the sliding rod 204.

[0034] like Figure 2 and Figure 5As shown, the unlocking assembly includes a lifting bracket 201, a sliding card rod 202, a fixed push rod 2021 and a return spring 203. The lifting bracket 201 is symmetrically slidably provided on the sedimentation frame 2, and a sliding card rod 202 is slidably provided on each lifting bracket 201. Each sliding card rod 202 is provided with a semicircular card plate at one end close to the sedimentation rod 102, and the semicircular card plate on the sliding card rod 202 can be inserted into the top of the sliding pull rod 1021. A fixed push rod 2021 is fixedly connected to each sliding card rod 202, and the fixed push rod 2021 is located directly above the L-shaped block 206. A return spring 203 is provided between the sliding card rod 202 and the sedimentation frame 2.

[0035] When the sinking rod 102 descends, under the action of the sliding rod 1021, the sliding card rod 202, the lifting bracket 201, the fixed push rod 2021 and the return spring 203 will descend accordingly. When the fixed push rod 2021 contacts the L-shaped block 206, the sliding card rod 202 and the sliding rod 1021 are blocked and no longer descend with the sinking rod 102. When the top of the sliding rod 1021 contacts the fixed connecting block 103, as the sinking rod 102 continues to descend, the fixed connecting block 103 pushes the sliding rod 1021 and the sliding card rod 202 to descend, and the fixed push rod 2021 can move the L-shaped block 206. 06 is pushed into the sliding rod 204 and compresses the supporting spring 207. At this time, the fixed pushing rod 2021 is inserted into the sliding rod 204. After the L-shaped block 206 is out of contact with the sinking frame 2, the sliding rod 204 will slide outward along the sinking frame 2 under the push of the connecting spring 205 and make the arc plate 2041 out of contact with the sinking rod 102. When the sliding rod 204 moves, it will drive the sliding card rod 202 to slide along the lifting bracket 201 through the fixed pushing rod 2021 and compress the reset spring 203, so that the sliding card rod 202 is out of contact with the sliding pull rod 1021, so as to release the restriction on the sinking rod 102.

[0036] like Figure 5 and Figure 7As shown, the underground settlement indicating mechanism includes an underground settlement indicator light 2001, a No. 1 U-shaped tube 3, a sliding connection frame 301, a supporting spring 302, a sliding pressure rod 303, an L-shaped rod 304, a connecting inclined rod 305 and a No. 1 sliding rheostat 306. The underground settlement indicator light 2001 is installed on the settlement frame 2, the No. 1 U-shaped tube 3 is installed on the settlement cylinder 101, the sliding connection frame 301 is slidably connected to the fixed guide rod 104, a supporting spring 302 is provided between the sliding connection frame 301 and the fixed guide rod 104, and the supporting spring 302 is used to support the sliding connection frame 301 to prevent the sliding connection frame 301 from freely falling along the fixed guide rod 104, and the sliding pressure rod 303 is slidably connected in the No. 1 U-shaped tube 3. The sliding connection frame 301 is fixedly connected with the sliding pressure rod 303, and an L-shaped rod 304 is slidingly connected in the No. 1 U-shaped tube 3. The No. 1 U-shaped tube 3 is filled with water. The water in the No. 1 U-shaped tube 3 is located between the sliding pressure rod 303 and the L-shaped rod 304, and the sliding pressure rod 303 and the L-shaped rod 304 seal the No. 1 U-shaped tube 3. A No. 1 sliding rheostat 306 is installed on the end of the sedimentation cylinder 101 close to the underground sedimentation indicator light 2001. The No. 1 sliding rheostat 306 and the underground sedimentation indicator light 2001 are in the same circuit group, and in the initial state, the paddle of the No. 1 sliding rheostat 306 is located at the position with the maximum resistance, and the L-shaped rod 304 and the paddle of the No. 1 sliding rheostat 306 are connected by a connecting diagonal rod 305.

[0037] When the sliding clamping rod 202 descends, it will contact the sliding connecting frame 301. At this time, the sliding connecting frame 301 is supported by the arc plate 2041 and cannot descend. When the two sliding rods 204 slide along the settlement frame 2 and move away from each other under the push of the connecting spring 205, the arc plate 2041 will move away from the bottom of the sliding connecting frame 301. At this time, the equipment has been installed. When the underground soil settles, the settlement rod 102 can be pulled by the rotating block 1022 to slide downward along the settlement cylinder 101. The settlement rod 102 will push the sliding pull rod 1021 and the sliding connecting frame 301 to descend through the fixed connecting block 103. The sliding connecting frame 301 moves along the fixed guide rod 104 to When the sliding connecting frame 301 descends, it will drive the sliding pressure rod 303 to slide downward along the No. 1 U-shaped tube 3. The descent of the sliding pressure rod 303 will push the L-shaped rod 304 to rise through the water in the No. 1 U-shaped tube 3. The rising of the L-shaped rod 304 will pull the paddle on the No. 1 sliding rheostat 306 to rise through the connecting oblique rod 305, so as to reduce the resistance value of the No. 1 sliding rheostat 306 and increase the current passing through the underground settlement indicator light 2001. During the settlement of the underground soil, the current flowing through the underground settlement indicator light 2001 will gradually increase, and the underground settlement indicator light 2001 will gradually become brighter, which has the effect of reminding.

[0038] Embodiment 3: Based on embodiment 2, Figure 6As shown, it also includes a wedge block 208 and an ejection spring 209. The wedge block 208 is slidably connected inside the sliding rod 204, and an ejection spring 209 is provided between the wedge block 208 and the sliding rod 204. The ejection spring 209 can push the wedge block 208 out from the sliding rod 204.

[0039] After the connecting spring 205 pushes the sliding rod 204 to slide along the sedimentation frame 2, when the connecting spring 205 returns to its original state, the ejection spring 209 will push the wedge block 208 outward from the sliding rod 204. At this time, the wedge block 208 will be stuck on the outside of the sedimentation frame 2 to limit the movement of the sliding rod 204, thereby preventing the two sliding rods 204 from sliding toward the inside of the sedimentation frame 2 due to external forces, and preventing the arc plate 2041 from contacting the sedimentation rod 102 again and affecting the monitoring effect.

[0040] like Figure 8 and Fig. 9 As shown, it also includes a wall settlement monitoring mechanism, which includes a wall settlement indicator light 2002, a second U-shaped tube 4, an L-shaped pressure rod 401, a U-shaped rod 402, a fixed frame 403 and a second sliding rheostat 404. The wall settlement indicator light 2002 is installed on the settlement frame 2, and the wall settlement indicator light 2002 and the underground settlement indicator light 2001 are symmetrical about the settlement frame 2. The fixed frame 403 is fixedly connected to the fixed bottom plate 1, the second U-shaped tube 4 is installed on the fixed bottom plate 1 and the fixed frame 403, and the L-shaped pressure rod 401 is slidably connected in the second U-shaped tube 4. The top of the L-shaped pressure rod 401 contacts the settlement frame 2, and the fixed frame 403 slides on the fixed frame 403. A U-shaped rod 402 is connected, and the other end of the U-shaped rod 402 is slidably connected in the No. 2 U-shaped tube 4. The No. 2 U-shaped tube 4 is filled with water. The water in the No. 2 U-shaped tube 4 is located between the L-shaped pressure rod 401 and the U-shaped rod 402, and the L-shaped pressure rod 401 and the U-shaped rod 402 seal the No. 2 U-shaped tube 4. A No. 2 sliding rheostat 404 is fixedly connected to the side of the sedimentation cylinder 101 close to the wall settlement indicator light 2002. The No. 2 sliding rheostat 404 and the wall settlement indicator light 2002 are in the same circuit group. In the initial state, the paddle of the No. 2 sliding rheostat 404 is located at the position with the maximum resistance, and the U-shaped rod 402 is fixedly connected to the paddle on the No. 2 sliding rheostat 404.

[0041] The settlement frame 2 is fixed on the wall. When the wall settles downward, the wall will drive the settlement frame 2 to slide downward along the fixed guide rod 104. When the settlement frame 2 descends, it will push the L-shaped pressure rod 401 to slide downward along the second U-shaped tube 4. When the L-shaped pressure rod 401 slides downward along the second U-shaped tube 4, the water inside it will push the U-shaped rod 402 to rise. When the U-shaped rod 402 rises, it will drive the paddle on the second sliding rheostat 404 to rise, so as to reduce the resistance value of the second sliding rheostat 404, so that the current passing through the wall settlement indicator light 2002 becomes larger. In the process of the wall settling downward, the current passing through the wall settlement indicator light 2002 gradually increases, and the wall settlement indicator light 2002 will gradually become brighter, which serves as a reminder.

[0042] like Fig.10 and Fig.11 As shown, it also includes a wall tilt indicator light 2003, a battery 5, a wire 501, a hollow tube 502, a limit block 5021 and a conductive ball 503. The wall tilt indicator light 2003 and the battery 5 are installed on the settlement frame 2. The wire 501 is provided on the settlement frame 2. The wire 501 connects the battery 5 and the wall tilt indicator light 2003. The hollow tube 502 is installed on the settlement frame 2. The wire 501 passes through the hollow tube 502 and does not touch each other. The two monitoring devices are used in conjunction and fixed. At the same wall, the hollow tubes 502 on the settlement frames 2 in the two monitoring devices are connected and a conductive ball 503 is provided inside the hollow tube 502. A limit block 5021 is provided inside the hollow tube 502. The limit blocks 5021 on the two hollow tubes 502 just limit the position of the conductive ball 503. When the settlement frame 2 tilts, the conductive ball 503 can bypass the limit block 5021 and slide along the hollow tube 502 to the wire 501, so that the circuit between the battery 5 and the wall tilt indicator light 2003 is connected.

[0043] When using this device, two monitoring devices are grouped together, and the devices in the same group need to be installed on the same wall. When installing the devices, align the two hollow tubes 502 so that the conductive ball 503 is located between the two limit blocks 5021, which can prevent the conductive ball 503 from rolling freely in the hollow tube 502. When the wall deflects to one side, the hollow tube 502 in the monitoring device on the corresponding side will tilt, and the conductive ball 503 inside it will pass through the top of the limit block 5021 and roll along the hollow tube 502. When the conductive ball 503 rolls to the end of the hollow tube 502 away from the limit block 5021, the conductive ball 503 will contact the wire 501, and the battery 5 and the wall tilt indicator light 2003 will be connected, and the wall tilt indicator light 2003 will light up, serving as a prompt.

[0044] like Figure 3 and Figure 4As shown, the bottom end of the sinker rod 102 is conical, and a thread is provided on the conical structure at the bottom end of the sinker rod 102; when the connecting block 103 is rotated and fixed, the conical threaded structure can make the sinker rod 102 easier to insert into the soil, thereby improving the installation efficiency.

[0045] like Figure 2 As shown, the fixed base plate 1 is a straight steel plate with threaded holes, and the fixed base plate 1 is fixed to the concrete floor by expansion screws; the fixed base plate 1 is screwed to the concrete floor by the expansion screws to prevent the equipment from being displaced by external forces.

[0046] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
