Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a buried survey line protection and usage device. Background Technology

[0002] The buried survey line protection and usage device is a comprehensive device specifically designed for underground survey lines. It typically consists of a protective sleeve or protective layer with corrosion resistance, pressure resistance, and tensile strength; positioning components to fix the survey line position and prevent it from moving or being damaged in the soil; marking components to facilitate quick identification of the survey line's direction and location during construction or maintenance; and interfaces or auxiliary structures to facilitate survey line connection, debugging, and data reading. It can effectively resist damage to the survey line from external factors such as soil pressure, groundwater erosion, and collisions with construction machinery, ensuring the stable operation of the survey line in a long-term buried state. At the same time, it provides convenience for the installation, maintenance, and daily use of the survey line, and is widely used in geological monitoring, civil engineering, underground pipeline construction, and other fields.

[0003] The buried survey line protection and usage device uses a protective sleeve or protective layer with anti-corrosion, pressure-resistant, and tensile-resistant properties to wrap the survey line, forming a physical barrier to isolate it from external damage such as soil pressure, groundwater erosion, and collisions with construction machinery. At the same time, positioning components are used to stabilize the survey line in a preset position to prevent it from shifting. Identification components use specific marks or signals to indicate the direction and position of the survey line for quick positioning. Interfaces or auxiliary structures provide convenient channels for connecting, debugging, and reading data from the survey line. All parts work together to ensure that the survey line is protected from external interference while ensuring that it can stably transmit signals or data, thus achieving effective protection and convenient use of the survey line.

[0004] In existing technologies, when a survey line is subjected to external forces such as tension, compression, or soil settlement, it cannot recover to its original correct position or shape with the help of rebound force. This easily causes the survey line to be in a state of tension, twisting, or bending for a long time, which increases the risk of the survey line breaking due to continuous stress and unstable signal transmission. At the same time, it also increases the difficulty of adjusting the position of the survey line during later maintenance, reduces the dynamic protection capability of the device for the survey line and the overall service life. Therefore, a buried survey line protection and usage device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an embedded measuring line protection and usage device, which aims to improve the problems in the existing technology that are prone to causing line breakage, signal attenuation, etc., and also increase the difficulty of adjustment during manual maintenance and weaken the dynamic protection effect of the device on the measuring line.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An embedded measuring line protection and usage device includes concrete, a rebound mechanism installed inside the concrete, a cubic cylinder fixedly connected inside the concrete, a sealing mechanism installed at the front end of the cubic cylinder, and two hinges fixedly connected to the rear end of the cubic cylinder.

[0008] The rebound mechanism includes a steel pipe, the outer wall of which is fixedly connected to the interior of the concrete, a template is fixedly connected to the top inner wall of the steel pipe, a measuring line is slidably connected to the inner wall of the template, a measuring line plug is fixedly connected to the top of the measuring line, a support leg is slidably connected to the outer wall of the steel pipe, and a reset component is sleeved on the outer wall of the measuring line.

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a spring, the inner wall of which is sleeved on the outer wall of the measuring line. A thin steel plate is fixedly connected to the outer wall of the measuring line, and a sealing ring is fixedly connected to the outer wall of the thin steel plate.

[0011] As a further description of the above technical solution:

[0012] The sealing mechanism includes a square box, with two guide rods fixedly connected to the inner wall of each square box. Springs are fitted on the outer walls of the two guide rods, and clamps are slidably connected to the outer walls of the two guide rods. Sliding plates are fixedly connected to the bottom ends of the two clamps. A top cover is fixedly connected to the front end of the hinge, with two fixing plates fixedly connected to the front end of the top cover. An inclined block is fixedly connected to the bottom end of the two fixing plates, and a sealing ring is fixedly connected to the bottom end of the top cover.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the sealing ring is slidably connected to the inner wall of the steel pipe, the bottom end of the support leg is in contact with the top end of the concrete, and the inner wall of the template has holes.

[0015] As a further description of the above technical solution:

[0016] One end of the spring is fixedly connected to the bottom end of the template, and the other end of the spring is fixedly connected to the top end of the thin steel plate.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the clamp is slidably connected to the inner wall of the square box, and the outer wall of the inclined block is in contact with the front end of the clamp;

[0019] As a further description of the above technical solution:

[0020] The outer wall of the sliding plate is slidably connected to the inner wall of the square box, and the outer wall of the second sealing ring is in contact with the inner wall of the cube cylinder;

[0021] As a further description of the above technical solution:

[0022] One end of the second spring is fixedly connected to the inner wall of the square box, and the other end of the second spring is fixedly connected to the outer wall of the clamp.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the steel pipe is fixed in the concrete. The measuring line plug is driven by force to slide along the template, compressing the spring of the reset component. The thin steel plate and the sealing ring assist in the sealing. The support leg stabilizes the steel pipe. After the external force disappears, the spring resets and pulls the measuring line back to its original position. After the measuring line is subjected to external force, soil compression, or settlement, the rebound force enables the measuring line to quickly return to its original correct position and shape. This avoids the measuring line being in a state of tension, twisting, or bending for a long time, reducing problems such as breakage and unstable signal transmission caused by continuous force. It also reduces the difficulty of adjusting the position of the measuring line during later maintenance, improves the device's dynamic protection capability for the measuring line, extends its overall service life, and ensures the stability of the measuring line signal or data transmission.

[0025] 2. In this utility model, when the top cover is closed, the inclined block squeezes the clamp to slide along the guide rod and compresses the second spring. After the clamp is reset, it engages with the fixing plate to fix the top cover. The second sealing ring achieves a seal, which can effectively prevent the slurry during concrete pouring, moisture and debris in the construction environment from entering, avoiding these substances from corroding key components such as the measuring line plug, preventing the measuring line from becoming abnormal or damaged due to moisture or blockage, ensuring the long-term stable operation of the measuring line. The relatively independent space formed by the seal can reduce the impact of external temperature and humidity fluctuations on the internal measuring line and improve the accuracy of measurement data.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an embedded measuring line protection and usage device. Concrete 1 provides an embedded installation foundation for subsequent components, maintaining a stable position. The device includes concrete 1, inside which a rebound mechanism 2 is installed. The rebound mechanism 2 relies on concrete 1 to achieve stable operation, ensuring accurate and reliable measurement and rebound functions. A cubic cylinder 3 is fixedly connected inside concrete 1, achieving embedded installation of the cubic cylinder 3 through concrete 1, providing an installation carrier for the sealing mechanism 4 and hinges 5, forming a protective space. The front end of the cubic cylinder 3 is equipped with the sealing mechanism 4, providing an installation position for the sealing mechanism 4. The sealing mechanism 4 achieves a sealing function through the cylinder, preventing impurities from entering the interior. Two hinges 5 are fixedly connected to the rear end of each cubic cylinder 3. The hinges 5 provide rotation fulcrums for the opening and closing components of the cylinder, allowing the cylinder to be flexibly opened for convenient inspection and maintenance of the internal structure.

[0034] The rebound mechanism 2 includes a steel pipe 21, which is the main support structure of the rebound mechanism 2 and provides an installation frame for components such as the template 22 and the measuring line 23. The outer wall of the steel pipe 21 is fixedly connected to the interior of the concrete 1, and the concrete 1 provides a foundation for the steel pipe 21, ensuring the stability of the steel pipe 21 and the internal components. The template 22 is fixedly connected to the top inner wall of the steel pipe 21, and the template 22 is fixed at the top of the steel pipe 21 to provide stable support for the template 22. The template 22 provides a sliding guide for the measuring line 23. The fixing of the steel pipe 21 ensures the accurate movement trajectory of the measuring line 23. The measuring line 23 is slidably connected to the inner wall of the template 22, and the inner wall of the template 22 provides a sliding track for the measuring line 23, limiting the movement direction of the measuring line 23.

[0035] A measuring line plug 24 is fixedly connected to the top of the measuring line 23. The measuring line plug 24 receives external force and transmits it to the measuring line 23. A support leg 25 is slidably connected to the outer wall of the steel pipe 21. The support leg 25 cooperates with the concrete 1 to prevent the steel pipe 21 from tilting under force and to ensure the verticality of the rebound mechanism 2. A reset component 26 is sleeved on the outer wall of the measuring line 23. The reset component 26 undergoes elastic deformation as the measuring line 23 moves. When the external force disappears, the reset component 26 drives the measuring line 23 to reset, realizing the automatic rebound function of the device.

[0036] Reference Figures 1 to 3 The reset assembly 26 includes a spring 261, which is the core elastic component of the reset assembly 26. The spring 261 provides power for the reset action. The inner wall of the spring 261 is sleeved on the outer wall of the measuring line 23. The inner wall of the spring 261 is sleeved on the outer wall of the measuring line 23 and undergoes compression or elongation deformation as the measuring line 23 slides. A thin steel plate 262 is fixedly connected to the outer wall of the measuring line 23. The thin steel plate 262 limits the spring 261, so that the deformation force of the spring 261 is concentrated on the measuring line 23, thereby improving the reset efficiency. A sealing ring 263 is fixedly connected to the outer wall of the thin steel plate 262. The sealing ring 263 moves with the thin steel plate 262, enhancing the sealing with the inner wall of the template 22 and preventing impurities from entering and affecting the operation of the component.

[0037] Reference Figures 2 to 4 The sealing mechanism 4 includes a square box 41, which serves as the mounting base. The square box 41 provides a fixed space for internal guide rods 42, springs 43, and other components. Two guide rods 42 are fixedly connected to the inner wall of the square box 41, providing rigid fixation and ensuring parallel axes. Springs 43 are sleeved on the outer wall of both guide rods 42, providing extension and contraction guidance and preventing spring twisting. Clamps 44 are slidably connected to the outer wall of both guide rods 42, providing sliding support for the clamps 44 and allowing them to move smoothly along the guide rods 42. Sliding plates 45 are fixedly connected to the bottom of both clamps 44, linking the two clamps 44 together to ensure synchronous operation.

[0038] The front end of the hinge 5 is fixedly connected to the top cover 46, which provides a pivot point for the top cover 46 to rotate, allowing the top cover 46 to open and close flexibly around the hinge 5. The front end of the top cover 46 is fixedly connected to two fixing plates 47, which rotate synchronously with the top cover 46. The bottom ends of the two fixing plates 47 are fixedly connected to inclined blocks 48, which press the clamp 44 when the top cover 46 is closed, causing the clamp 44 to automatically retract and eventually reset and engage. The bottom end of the top cover 46 is fixedly connected to a second sealing ring 49, which fits against the cube cylinder 3 when the top cover 46 is closed, forming a sealing barrier.

[0039] Reference Figures 2 to 4 The outer wall of the sealing ring 263 is slidably connected to the inner wall of the steel pipe 21. The sealing ring 263 prevents concrete debris or water from seeping into the interior of the steel pipe 21. Simultaneously, it slides synchronously with the measuring line 23, without affecting the flexibility of the rebound action. The bottom end of the support leg 25 contacts the top end of the concrete 1, enhancing the stability of the steel pipe 21 through its support, dispersing the pressure on the steel pipe 21, and preventing the steel pipe 21 from tilting or displacing due to uneven stress inside the concrete 1. Holes are provided in the inner wall of the template 22, providing a passage for the measuring line 23 to pass through, restricting... The radial displacement of the measuring line 23 ensures that it only slides axially. At the same time, the hole size matches the measuring line 23 to reduce the gap between them and improve the guiding accuracy. One end of the spring 261 is fixedly connected to the bottom end of the template 22, and the other end of the spring 261 is fixedly connected to the top end of the thin steel plate 262. The two ends of the spring 261 are fixed to the bottom end of the template 22 and the top end of the thin steel plate 262 respectively, forming an elastic connection structure. When the measuring line 23 moves the thin steel plate 262 downward, the spring is compressed. After the external force disappears, the spring force pushes the thin steel plate 262 to reset, realizing the automatic rebound of the measuring line 23.

[0040] The outer wall of the clamp 44 is slidably connected to the inner wall of the square box 41. The inner wall of the square box 41 provides lateral support for the clamp 44, restricting it to slide only along the direction of the guide rod 42, preventing the clamp 44 from swaying during movement, and ensuring precise engagement with the fixing plate 47. The outer wall of the inclined block 48 contacts the front end of the clamp 44. When the cover 46 is closed, the inclined block 48 presses the clamp 44 through the inclined surface, converting the rotational force of the cover 46 into the lateral thrust of the clamp 44, causing the clamp 44 to retract along the guide rod 42, facilitating the smooth closing of the cover 46 and the reset and locking of the clamp 44. The outer wall of the sliding plate 45 is slidably connected to the inner wall of the square box 41. The inner wall of the square box 41 restricts the movement direction of the sliding plate 45, allowing the sliding plate 45 to drive the two clamps. The synchronous operation of 44 ensures that the clamp 44 is subjected to balanced force during opening and closing, avoiding one-sided jamming. The outer wall of the sealing ring 49 contacts the inner wall of the cube cylinder 3. When the top cover 46 is closed, the sealing ring is squeezed and deformed, filling the gap between the top cover 46 and the cylinder to form a reliable seal and prevent external impurities from entering the cylinder. One end of the spring 43 is fixedly connected to the inner wall of the square box 41, and the other end of the spring 43 is fixedly connected to the outer wall of the clamp 44. The two ends of the spring 43 are respectively fixed to the inner wall of the square box 41 and the outer wall of the clamp 44, providing a reset elastic force for the clamp 44. When the inclined block 48 is disengaged from the clamp 44, the spring pushes the clamp 44 to reset and engage with the fixing plate 47, ensuring that the top cover 46 is stably locked.

[0041] Working principle: When the rebound mechanism 2 is working, the steel pipe 21 is fixed inside the concrete 1 to provide stable support. The support leg 25 slides along the outer wall of the steel pipe 21 to assist in fixing the overall structure. When the measuring line plug 24 is pulled by external force, it drives the measuring line 23 to slide along the inner wall of the template 22, and simultaneously squeezes the spring 261 of the reset component 26. The thin steel plate 262 moves with the measuring line 23. The sealing ring 263 on its outer wall fits against the inner wall of the template 22 to achieve a seal and prevent impurities from entering. When the external force disappears, the spring 261 elastically resets, pulling the measuring line 23 and the measuring line plug 24 back to the initial position, completing one rebound action. With the help of the rebound force, the measuring line quickly returns to its original correct position and shape, avoiding the measuring line being in a state of tension, twisting or bending for a long time, and reducing problems such as breakage and unstable signal transmission caused by continuous force.

[0042] When the cube cylinder 3 needs to be sealed, the top cover 46 is closed, the fixing plate 47 drives the inclined block 48 to squeeze the clamp 44, causing it to slide along the guide rod 42 and compress the second spring 43. The sliding plate 45 moves with the clamp 44. After the second spring 43 returns to its original position, the clamp 44 engages with the fixing plate 47 to fix the top cover 46, and the second sealing ring 49 fits and seals. When opening, the sliding plate 45 is pushed to disengage the clamp 44 from the fixing plate 47, completing the opening and closing and sealing. Through the sealing mechanism 4, the long-term stable operation of the measuring line is ensured. The relatively independent space formed by the seal can reduce the impact of external temperature and humidity fluctuations on the internal measuring line and improve the accuracy of the measurement data.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
