Description

Technical Field

[0001] This utility model relates to the field of crack monitoring technology, and more specifically, to a quantitative monitoring device for crack changes in water conservancy projects. Background Technology

[0002] Hydraulic engineering projects are engineering works constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. They are also called water engineering projects. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing hydraulic engineering projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the water needs of people's lives and production. Hydraulic engineering projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives.

[0003] Currently, some existing quantitative monitoring devices for crack changes in water conservancy projects use a mounting base to fix the entire device in a designated position and then use a camera on the device to monitor crack changes. The mounting base is connected to the ground by a pin. Since the pin has a pointed head, there is a certain safety hazard during transportation. Therefore, we provide a quantitative monitoring device for crack changes in water conservancy projects. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative monitoring device for crack changes in hydraulic engineering, in order to solve the problems mentioned in the background art.

[0005] Currently, some existing quantitative monitoring devices for crack changes in water conservancy projects use a mounting base to fix the entire device in a designated position and then use a camera on the device to monitor crack changes. The mounting base is connected to the ground by a pin. Since the pin has a sharp point, there is a certain safety hazard during transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quantitative monitoring device for crack changes in water conservancy projects includes a mounting base. A mounting plate is fixedly connected to the top of the mounting base. A threaded rod is rotatably connected between the mounting plate and the mounting base. A movable plate is sleeved on the outside of the threaded rod, and the movable plate is threadedly connected to the threaded rod. A helical pin is rotatably connected inside the movable plate. A groove is formed inside the helical pin, and a sliding rod is slidably connected inside the groove. The sliding rod is rotatably connected to the mounting plate. A first gear is sleeved on the outside of the sliding rod, and the first gear is fixedly connected to the sliding rod. A second gear is sleeved on the outside of the threaded rod, and the second gear is fixedly connected to the threaded rod. The first gear and the second gear are meshed together.

[0008] Preferably, both the slide groove and the slide rod have square cross-sections, and the outer wall of the slide rod is in contact with the inner wall of the slide groove.

[0009] Preferably, a mounting rod is fixedly connected to the top of the mounting base, and a camera is fixedly connected to the outer end of the mounting rod away from the mounting base.

[0010] Preferably, a servo motor is fixedly connected to the top of the mounting plate, the output shaft of the servo motor vertically penetrates the mounting plate and extends to the bottom of the mounting plate, the output shaft of the servo motor is rotatably connected to the mounting plate, and the threaded rod is fixedly connected to the output end of the servo motor.

[0011] Preferably, the mounting rod is externally fixedly connected to a control panel, and both the camera and the servo motor are electrically connected to the control panel.

[0012] Preferably, a sleeve is fitted around the outside of the spiral pin, and a scraper is fixedly connected inside the sleeve, the scraper being used in conjunction with the spiral pin.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The servo motor is started, driving the threaded rod to rotate forward. The threaded rod, through the movable plate, moves the helical pin downward and inserts it into the ground. During this process, the threaded rod drives the sliding rod to rotate through the first and second gears. The sliding rod, in conjunction with the sliding groove, drives the helical pin to rotate, so that the helical pin rotates while moving downward, allowing it to better insert into the ground and ensuring overall stability. At the same time, controlling the servo motor to reverse the direction can retract the helical pin, ensuring that the tip of the helical pin is not directly exposed, making it safer to transport. Furthermore, the scraper inside the sleeve can scrape off the dirt adhering to the helical pin, ensuring its cleanliness. Attached Figure Description

[0022] Furthermore, both the slide groove 6 and the slide rod 7 have square cross-sections. The outer wall of the slide rod 7 fits against the inner wall of the slide groove 6, allowing the spiral pin 5 to slide on the slide rod 7. At the same time, the slide rod 7 can also drive the spiral pin 5 to rotate.

[0023] Furthermore, a mounting rod 10 is fixedly connected to the top of the mounting base 1, and a camera 11 is fixedly connected to the outer end of the mounting rod 10 away from the mounting base 1, so as to monitor the changes in the crack.

[0024] Furthermore, a servo motor 12 is fixedly connected to the top of the mounting plate 2. The output shaft of the servo motor 12 passes vertically through the mounting plate 2 and extends to the bottom of the mounting plate 2. The output shaft of the servo motor 12 is rotatably connected to the mounting plate 2. The threaded rod 3 is fixedly connected to the output end of the servo motor 12.

[0027] The steps for using this utility model are as follows: When using this quantitative monitoring device for crack changes in water conservancy projects, after placing the mounting base 1 in the designated position, start the servo motor 12 to drive the threaded rod 3 to rotate forward. The threaded rod 3 drives the spiral pin 5 to move downward and insert into the ground through the movable plate 4. During the process, the threaded rod 3 drives the sliding rod 7 to rotate through the first gear 8 and the second gear 9. The sliding rod 7, in conjunction with the sliding groove 6, drives the spiral pin 5 to rotate, so that the spiral pin 5 rotates itself while moving downward, allowing the spiral pin 5 to better insert into the ground and ensure overall stability. At the same time, controlling the servo motor 12 to reverse will retract the spiral pin 5, so that the tip of the spiral pin 5 is not directly on the outside, making it safer to transport. Moreover, the scraper 15 inside the sleeve 14 can scrape off the mud adhering to the spiral pin 5, ensuring the cleanliness of the spiral pin 5.
