Description

Technical Field

[0001] The utility model belongs to the technical field of ground monitoring, and particularly relates to a novel device for ground monitoring in a subsidence area. Background Technique

[0002] In order to prevent geological disasters and engineering accidents, monitoring devices are placed at positions prone to subsidence for monitoring.

[0003] The utility model patent with the authorization announcement number CN218382774U discloses a novel device for ground monitoring in a subsidence area, including: a baffle; a telescopic sleeve, the telescopic sleeve is slidably connected inside the baffle, and a fixing plate is threadedly connected to the top of the inner side surface of the telescopic sleeve; a mounting plate, the mounting plates are respectively fixedly installed on both sides of the top of the fixing plate, a sliding rod is slidably connected inside the mounting plate, a contact terminal is fixedly installed at one end of the sliding rod, and a spring is sleeved on the outer side surface of the sliding rod. The novel device for ground monitoring in a subsidence area provided by the utility model replaces the telescopic sleeve according to different soil components, different degrees of soil compaction and different depths to be detected. In this way, the adaptability of the device is increased, and it can be used at different depths. And by clamping the contact terminal between the baffles and sliding the stopper on the outer side surface of the pull rope, and rubber beans can be used for fixation, the device can also be used at different depths.

[0004] However, the above mechanism has the following problems: when the ground subsides, the bottom of the telescopic sleeve lacks support and slides downward. However, the side surface of the telescopic sleeve will generate friction with the soil. Therefore, in order to enable the telescopic sleeve to move downward effectively, a relatively heavy metal block needs to be set to press down the telescopic sleeve, which will greatly increase the weight of the device and is not conducive to the carrying of the device; in addition, the alarm mechanism inside the protective cover has a relatively complicated structure, is not easy to maintain and is prone to damage. Content of the Utility Model

[0005] Aiming at the above problems, the purpose of the utility model is to provide a novel device for ground monitoring in a subsidence area, which solves the problems that the existing ground monitoring device in the subsidence area is too heavy to carry and the alarm mechanism inside the protective cover has a relatively complicated structure, is not easy to maintain and is prone to damage.

[0006] To achieve the above objectives, the technical solution adopted by the present utility model is as follows: A new type of ground monitoring device for a subsidence area, comprising an outer sleeve tube. An inner sliding tube is slidably installed inside the outer sleeve tube. The inner sliding tube is composed of a tube body and a threaded cover that are threadedly connected to each other. One end of a connecting rope is tied to the inner sliding tube, and the other end of the connecting rope is tied to one end of a conductive plate in an alarm mechanism. The conductive plate is rotatably installed on a support frame through a connecting shaft. The other end of the conductive plate is adaptively clamped inside an insulating reed and is arranged below a first conductive column. The first conductive column is installed on the insulating reed. A second conductive column is connected to the conductive plate. The second conductive column and the first conductive column are connected in series with an alarm and a power source through wires. The alarm, the power source, the insulating reed, and the support frame are all installed on an end plate. The end plate is threadedly connected to a protective cover. The end plate is installed at the top of the outer sleeve tube. A ground nail is inserted into the end plate.

[0007] The beneficial effects of the present utility model are as follows: The operator can pour soil into the split tube body to increase the weight of the inner sliding tube, reducing the weight of the device during carrying while ensuring the reliability of the downward fall of the inner sliding tube. The conductive plate can be pulled by the downward-falling inner sliding tube to contact and conduct the circuit of the power source and the alarm, achieving an alarm with a simple and reliable structure.

[0008] To prevent the alarm mechanism from giving a false alarm during the installation of the device for the convenience of the people;

[0009] As a further improvement of the above technical solution: The insulating reed is composed of two V-shaped reed plates arranged oppositely on both sides of the conductive plate.

[0010] The beneficial effect of this improvement is that the insulating reed can provide a certain clamping force for the conductive plate, preventing the conductive plate from contacting the first conductive column and giving a false alarm when not pulled by the connecting rope.

[0011] To give a timely and effective alarm when the first conductive column is in contact with the conductive plate;

[0012] As a further improvement of the above technical solution: The negative pole and the positive pole of the power source are respectively connected to the negative pole of the alarm and the second conductive column through wires, and the first conductive column is connected to the positive pole of the alarm through a wire.

[0013] The beneficial effect of this improvement is that after the conductive plate is in contact with the first conductive column, the circuit of the alarm and the power source is closed, achieving a fast and effective alarm.

[0014] To effectively isolate and protect the alarm mechanism;

[0015] As a further improvement of the above technical solution: The alarm mechanism is installed inside the protective cover, and the protective cover is an inner-threaded cover structure with one end open.

[0016] The beneficial effects of this improvement are as follows: The protective cover can effectively isolate and protect the alarm mechanism, preventing external foreign objects from affecting the working performance and service life of the alarm mechanism.

[0017] In order to quickly and stably achieve the loading and unloading of the inner sliding tube;

[0018] As a further improvement of the above technical solution: One end of the threaded cap is provided with an external thread structure, and the tube body is a circular tube structure with an internal thread at one end for threaded connection with the threaded cap.

[0019] The beneficial effects of this improvement are as follows: The tube body and the threaded cap can be quickly and stably connected and disassembled through the threaded structure.

[0020] In order to further reduce the resistance when the inner sliding tube slides down;

[0021] As a further improvement of the above technical solution: The other end of the tube body is a conical structure.

[0022] The beneficial effects of this improvement are as follows: The conical structure at the bottom end of the tube body can increase the pressure of the tube body on the soil below, thereby improving the effect of the inner sliding tube sliding down.

[0023] In order to ensure the stability of the installation of the outer sleeve tube;

[0024] As a further improvement of the above technical solution: The number of the ground nails is multiple, and they are arranged at equal intervals around the axis of the end plate and the outer sleeve tube.

[0025] The beneficial effects of this improvement are as follows: Multiple ground nails can stably press the end plate on the ground, thereby ensuring the stability of the installation of the outer sleeve tube.

[0026] The parts not involved in this device are the same as the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0032] Example 1:

[0033] As Figure 1As shown in Figure 3, a new device for ground monitoring in a subsidence area includes an outer sleeve 1. An inner sliding tube 2 is slidably installed inside the outer sleeve 1. The inner sliding tube 2 is composed of a tube body 21 and a threaded cover 22 that are threadedly connected to each other. One end of a connecting rope 7 is tied to the inner sliding tube 2, and the other end of the connecting rope 7 is tied to one end of a conductive plate 63 in an alarm mechanism 6. The conductive plate 63 is rotatably installed on a support frame 65 through a connecting shaft 64. The other end of the conductive plate 63 is adaptively clamped inside an insulating reed 66 and is arranged below a first conductive column 67. The first conductive column 67 is installed on the insulating reed 66. A second conductive column 68 is connected to the conductive plate 63. The second conductive column 68 and the first conductive column 67 are connected in series with an alarm 62 and a power supply 61 through wires. The alarm 62, the power supply 61, the insulating reed 66, and the support frame 65 are all installed on an end plate 3. The end plate 3 is threadedly connected to a protective cover 5. The end plate 3 is installed at the top of the outer sleeve 1. A ground nail 4 is inserted into the end plate 3. An operator can pour soil into the split tube body 21 to increase the weight of the inner sliding tube 2, reducing the weight of the device during carrying while ensuring the reliability of the downward fall of the inner sliding tube 2. The conductive plate 63 can be pulled by the downward-falling inner sliding tube 2 to contact and conduct the circuit of the power supply 61 and the alarm 62, achieving an alarm with a simple and reliable structure. The insulating reed 66 is composed of two V-shaped reed plates arranged oppositely on both sides of the conductive plate 63. The insulating reed 66 can provide a certain clamping force for the conductive plate 63, preventing the conductive plate 63 from contacting the first conductive column 67 and causing false alarms when not pulled by the connecting rope 7. The negative pole and the positive pole of the power supply 61 are respectively connected to the negative pole of the alarm 62 and the second conductive column 68 through wires. The first conductive column 67 is connected to the positive pole of the alarm 62 through a wire. After the conductive plate 63 is connected to the first conductive column 67, the circuit of the alarm 62 and the power supply 61 is closed, achieving a fast and effective alarm. The alarm mechanism 6 is installed inside the protective cover 5. The protective cover 5 is an inner-threaded cover structure with one end open. The protective cover 5 can effectively isolate and protect the alarm mechanism 6, preventing external foreign objects from affecting the working performance and service life of the alarm mechanism 6. One end of the threaded cover 22 is provided with an external thread structure. The tube body 21 is a round tube structure with an internal thread at one end for threadedly connecting the threaded cover 22. The tube body 21 and the threaded cover 22 can be quickly and stably connected and disassembled through the threaded structure. The other end of the tube body 21 is a conical structure. The conical structure at the bottom of the tube body 21 can increase the pressure of the tube body 21 on the soil below, thereby improving the effect of the downward movement of the inner sliding tube 2. The number of ground nails 4 is multiple, and they are arranged at equal intervals around the axes of the end plate 3 and the outer sleeve 1. The multiple ground nails 4 can stably press and cover the end plate 3 on the ground, thus ensuring the stability of the installation of the outer sleeve 1.

[0034] The working principle of this technical solution is as follows: Slide the inner sliding tube 2 downward out of the outer sleeve 1, disassemble the tube body 21 and the threaded cap 22, pour a large amount of soil into the interior of the tube body 21 to increase the weight of the tube body 21, then tighten the threaded cap 22 and the tube body 21, and then insert the inner sliding tube 2 into the interior of the outer sleeve 1; Drill an installation hole with an appropriate depth on the ground, vertically place the inner sliding tube 2 and the outer sleeve 1 into the hole, and make the bottom surface of the end plate 3 be in flat contact with the ground. Then, unscrew the protective cover 5 from the end plate 3, and then adjust the length of the connecting rope 7 to make the connecting rope 7 be hung at one end of the conductive plate 63 with an appropriate tension, make the other end of the conductive plate 63 be clamped in the insulating reed 66 and not contact the conductive column one 67, keep the circuits of the alarm 62 and the power supply 61 disconnected, and then screw the protective cover 5 onto the end plate 3; When the ground collapses, the inner sliding tube 2 slides downward under the gravity of the soil inside the weight, pulls the conductive plate 63 to rotate through the connecting rope 7, and further makes the conductive plate 63 contact the conductive column one 67, so that the circuits of the power supply 61 and the alarm 62 are closed, and the alarm 62 is powered on to work and give an alarm.
