Description

Technical Field

[0001] This utility model relates to the field of rock and soil monitoring technology, and in particular to a rock and soil deformation monitoring device. Background Technology

[0002] A search revealed a Chinese patent with authorization number CN222211677U, which discloses a soil and rock deformation monitoring device. The device includes: a wire-laying reel with a measuring line fixedly mounted on one side, one end of which extends through the reel; an embedded tube on one side of the reel; multiple monitoring magnetic rings fixedly mounted on the surface of the embedded tube; and a limiting monitoring mechanism located on one side of the reel, used to automatically fix the measuring line when a monitoring magnetic ring is detected. The device can be used in conjunction with a clamping component. When the monitoring component senses the position of the monitoring magnetic ring, it can synchronously drive the clamping component to quickly clamp the measuring line, thus preventing the release of multiple measuring lines and resulting in measurement data errors. This makes measurement and monitoring more accurate.

[0003] The above patent has the following shortcomings: The above patent uses an air pump to drive two clamps to clamp and fix the measuring line. However, if the driving method is to use an air pump, gas leakage may occur, which will reduce the clamping force, affect the clamping effect and accuracy, and cause certain errors in the positioning of the measuring line, which will affect the monitoring effect. Therefore, it is urgent to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil and rock deformation monitoring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A soil and rock deformation monitoring device includes an embedded pipe, one end of which is provided with a wire feeding reel, a measuring line is wound around the outside of the wire feeding reel, the other end of the measuring line is provided with a monitoring mechanism, and the end of the wire feeding reel near the embedded pipe is provided with a limiting mechanism for limiting the monitoring mechanism.

[0007] The limiting mechanism includes a mounting plate. Mounting blocks are fixed to the top two sides of the mounting plate near the end of the wire feeding wheel. A guide rod is fixed to the side of the two mounting blocks that are close to each other. A fixing block is fixed to one side of the outer wall of the guide rod. A slider is provided on the other side of the outer wall of the guide rod when sliding. A connecting plate is fixed to the top of the slider and the fixing block. Anti-slip pads are provided on the side of the two connecting plates that are close to each other. An electromagnet is provided on the top and bottom of one side of one connecting plate. A metal magnet is provided on the top and bottom of one side of the other connecting plate. When the electromagnet is energized, it can attract the metal magnet, which can quickly clamp and fix the measuring line.

[0008] Preferably, one end of a spring is fixed to the end of the slider away from the fixed block, and the other end of the spring is fixedly connected to one side of one of the mounting blocks. The spring is located on the outer surface of the guide rod. When the electromagnet is de-energized, the spring can pull the slider to reset, preventing obstruction of the measurement line release.

[0009] Preferably, a storage battery is installed at the bottom of the mounting plate, and the electromagnet is electrically connected to a relay via a wire, and the relay is electrically connected to the storage battery.

[0010] Preferably, a first fixing plate is fixed to one end of the wire feeding reel, and a wire tube is fixed through both ends of the first fixing plate, through which the measuring wire can be fed.

[0011] Preferably, a second fixing plate is fixed at both ends of the top of the mounting plate on the other side, and a rubber guide roller is rotatably connected to the side of the two second fixing plates that are close to each other, and the measuring line passes between the two rubber guide rollers.

[0012] Preferably, the monitoring mechanism includes limiting blocks fixed at both ends inside the buried pipe, an adapter block slidably provided on the outer wall of the limiting block, a sensor installed at the bottom of the adapter block, a controller provided on the outer wall of the sensor, multiple monitoring magnetic rings provided on the outer wall of the buried pipe, and the other end of the measuring line fixedly connected to the top of the adapter block.

[0013] Preferably, the outer wall of the buried pipe is provided with multiple positioning rings, and the positioning rings and the monitoring magnetic ring are arranged alternately, and the bottom of the buried pipe is fixed with ground nails.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the adoption of a limiting mechanism, the gas leakage problem mentioned in the background technology is effectively solved. The controller transmits the signal to the relay, and then the relay controls the switch of the electromagnet, which can quickly attract the metal magnet and clamp and fix the measuring line through two connecting plates. By setting the current, the clamping force of the electromagnet on the measuring line can be adjusted. Compared with the clamping of the air pump, it is more stable and efficient, improving the efficiency of soil and rock monitoring.

[0016] 2. Because of the use of a spring, when the relay disconnects the current switch of the electromagnet, the spring will pull the slider to reset and move the corresponding connecting plate away from the electromagnet, thereby avoiding obstruction of the wire feeding operation and improving the wire feeding efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4A soil and rock deformation monitoring device includes an embedded pipe 1, a wire feeding wheel 2 at one end of the embedded pipe 1, a measuring line 201 wound around the outside of the wire feeding wheel 2, a monitoring mechanism at the other end of the measuring line 201, and a limiting mechanism for limiting the monitoring mechanism at the end of the wire feeding wheel 2 near the embedded pipe 1.

[0024] The limiting mechanism includes a mounting plate 3. Mounting blocks 302 are fixed to the top two sides of the mounting plate 3 near the end of the wire feeding wheel 2. The same guide rod 303 is fixed to the side of the two mounting blocks 302 that are close to each other. A fixing block 304 is fixed to one side of the outer wall of the guide rod 303. A slider 301 is provided on the other side of the outer wall of the guide rod 303 when sliding. A connecting plate 305 is fixed to the top of both the slider 301 and the fixing block 304. Anti-slip pads 308 are provided on the side of the two connecting plates 305 that are close to each other. An electromagnet 306 is provided on the top and bottom of one side of one connecting plate 305. A metal magnet 307 is provided on the top and bottom of one side of the other connecting plate 305. When the electromagnet 306 is energized, it can attract the metal magnet 307, which can quickly clamp and fix the measuring wire 201.

[0025] In this utility model, one end of a spring 309 is fixed to one end of the slider 301 away from the fixed block 304, and the other end of the spring 309 is fixedly connected to one side of one of the mounting blocks 302. The spring 309 is located on the outer surface of the guide rod 303. When the electromagnet 306 is de-energized, the spring 309 can pull the slider 301 to reset, preventing obstruction of the measurement line 201 from being laid.

[0026] In this utility model, a storage battery 501 is installed at the bottom of the mounting plate 3, and an electromagnet 306 is electrically connected to a relay via a wire, and the relay is electrically connected to the storage battery 501.

[0027] In this utility model, a first fixing plate 202 is fixed to one end of the wire feeding wheel 2, and a wire tube 203 is fixed through both ends of the first fixing plate 202. The measuring line 201 can pass through the wire tube 203 for wire feeding.

[0028] In this utility model, the top of the mounting plate 3 is fixed with two second fixing plates 4 at both ends. The two second fixing plates 4 are rotatably connected to the side of the two second fixing plates 4 that are close to each other, and the measuring line 201 passes through the two rubber guide rollers 401.

[0029] In this utility model, the monitoring mechanism includes a limiting block 100 fixed at both ends inside the buried pipe 1. An adapter block is slidably provided on the outer wall of the limiting block 100, and a sensor 6 is installed at the bottom of the adapter block. A controller 601 is provided on the outer wall of the sensor 6. The controller 601 is electrically connected to a relay. Multiple monitoring magnetic rings 102 are provided on the outer wall of the buried pipe 1, and the other end of the measuring line 201 is fixedly connected to the top of the adapter block.

[0030] In this utility model, the outer wall of the buried pipe 1 is provided with multiple positioning rings 101, and the positioning rings 101 and the monitoring magnetic ring 102 are arranged alternately. The bottom of the buried pipe 1 is fixed with a ground nail 103.

[0031] Working principle: In use, sensor 6 is first placed in the embedded tube 1. When sensor 6 senses the monitoring magnetic ring 102, it can simultaneously send a signal through controller 601 to control the relay switch, thereby fixing and limiting the measuring line 201, making it convenient for the monitor to record data. When sensor 6 senses the monitoring magnetic ring 102, it will control the relay switch through controller 601. When the relay is turned on, it will supply power to electromagnet 306 through battery 501. At this time, electromagnet 306 will be fully magnetic, and then it can instantly attract metal magnets 307. Metal magnets 307 will drive slider 301 to slide on the outer wall of guide rod 303. The electromagnet 307 will approach another metal magnet 307 and clamp and limit the measuring line 201. At this time, the anti-slip pad 308 will prevent the measuring line 201 from sliding and increase the friction. Through the cooperation of the electromagnet 306 and the metal magnet 307, the fixing effect of the measuring line 201 is better. When it is not necessary to limit the measuring line 201, the relay will de-energize the electromagnet 306, and then the electromagnet 306 will lose its magnetism. Then the spring 309 will pull the slider 301 to reset. The metal magnet 307 will move away from the outer wall of the measuring line 201, avoiding obstruction of the wire feeding operation of the measuring line 201. Then the two rubber guide rollers 401 will transport the measuring line 201.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
