Description

Technical Field

[0001] This utility model relates to the field of civil engineering testing technology, and in particular to an online monitoring device for the compaction of backfill soil. Background Technology

[0002] During the construction process, the compaction of backfill soil is a key indicator affecting the stability and durability of the foundation. Therefore, accurate and real-time online monitoring of the compaction of backfill soil is particularly important.

[0003] Existing online monitoring instruments for backfill compaction collect data through sensors and transmit it to a recording terminal, enabling dynamic monitoring of backfill compaction. However, in actual use, due to the complex environment at construction sites, operators are prone to accidentally touching the data recording module or operation panel of the monitoring instrument while performing other construction operations or equipment maintenance. Once an accidental touch occurs, it will lead to data recording errors, causing deviations in subsequent backfill compaction analysis and construction quality assessment based on these erroneous data, seriously affecting the monitoring results of backfill compaction. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing monitoring instruments are prone to data recording errors due to accidental touches by operators, affecting the monitoring results of backfill soil compaction and greatly reducing the practicality of online backfill soil compaction monitoring devices, making them inconvenient for users. Therefore, we propose an online backfill soil compaction monitoring device.

[0005] To achieve the above objectives, this application adopts the following technical solution: an online monitoring device for backfill soil compaction, comprising a monitoring instrument panel, a probe rod installed at the bottom of the monitoring instrument panel, a fixed plate fixedly connected to one end of the monitoring instrument panel, two movable slots opened at the top of the fixed plate, movable blocks slidably connected inside the movable slots, an L-shaped rod fixedly connected to the top of the movable blocks, a baffle fixedly connected to one end of the L-shaped rod, an extension plate fixedly connected to one end of the movable blocks, a slot opened at the top of the extension plate, and two fixed blocks fixedly connected to one end of the fixed plate;

[0006] The fixing block is equipped with a fixing mechanism for fixing the position of the baffle.

[0007] Preferably, the fixing mechanism includes a movable groove formed on the top of the fixing block, a storage spring fixedly connected to the bottom of the inner cavity of the movable groove, and a storage block fixedly connected to the top of the storage spring.

[0008] Preferably, the surface of the energy storage block is slidably connected to the inside of the slot, and the external shape of the energy storage block matches the internal shape of the slot.

[0009] Preferably, sliding grooves are provided on both sides of the inner cavity of the movable groove, and sliders are fixedly connected to both sides of the energy storage block, with the surface of the sliders slidably connected to the inside of the sliding grooves.

[0010] Preferably, limit grooves are formed at both ends of the inner cavity of the moving groove, and limit blocks are fixedly connected to both ends of the moving block, with the surface of the limit block slidingly connected to the inside of the limit groove.

[0011] Preferably, the baffle is made of a transparent material.

[0012] Preferably, a thrust spring is fixedly connected to one side of the movable block, and one side of the thrust spring is fixedly connected to one side of the inner cavity of the movable groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the operator presses down on the energy storage block and then moves the L-shaped rod. The L-shaped rod causes the baffle to move within the moving groove inside the fixed plate. When both baffles completely block the front end of the monitoring panel, the operator can release the energy storage block. The energy storage block, through the elastic force of the energy storage spring, inserts into the slot at the top of the extension plate, fixing the position of the baffle. This prevents the monitoring panel from being accidentally touched during the use of the online monitoring device for backfill compaction, thus avoiding data errors and effectively improving the practicality of the online monitoring device for backfill compaction.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-4 As shown, this utility model provides a technical solution: an online monitoring device for backfill soil compaction, including a monitoring panel 1, a probe rod 2 installed at the bottom of the monitoring panel 1, a fixed plate 3 fixedly connected to one end of the monitoring panel 1, two movable slots 18 opened at the top of the fixed plate 3, a movable block 4 slidably connected inside the movable slots 18, an L-shaped rod 5 fixedly connected to the top of the movable block 4, a baffle 6 fixedly connected to one end of the L-shaped rod 5, an extension plate 7 fixedly connected to one end of the movable block 4, a slot 8 opened at the top of the extension plate 7, two fixed blocks 9 fixedly connected to one end of the fixed plate 3, a fixing mechanism for fixing the position of the baffle 6 installed inside the fixed block 9, the fixing mechanism including a movable slot 10 opened at the top of the fixed block 9, the movable slot 10... A storage spring 11 is fixedly connected to the bottom of the inner cavity, and a storage block 12 is fixedly connected to the top of the storage spring 11. When the operator presses down on the storage block 12, the L-shaped rod 5 is moved. The L-shaped rod 5 will drive the baffle 6 to move in the moving groove 18 inside the fixed plate 3. When the two baffles 6 completely block the front end of the monitoring instrument panel 1, the operator can release the storage block 12. The storage block 12 will be inserted into the slot 8 at the top of the extension plate 7 by the elastic force of the storage spring 11, thus fixing the position of the baffle 6. This avoids the situation where the monitoring instrument panel 1 is accidentally touched when using the online monitoring device for backfill compaction, resulting in data errors. This effectively improves the practicality of the online monitoring device for backfill compaction.

[0022] Reference Figure 3 and Figure 4 As shown in this embodiment: the surface of the energy storage block 12 is slidably connected to the inside of the slot 8, and the external shape of the energy storage block 12 matches the internal shape of the slot 8. By setting the surface of the energy storage block 12 to be slidably connected to the inside of the slot 8, and the external shape of the energy storage block 12 matches the internal shape of the slot 8, when the energy storage block 12 is subjected to the elastic force of the energy storage spring 11, the energy storage block 12 can slide stably and smoothly into the inside of the slot 8, ensuring the firm fixation of the position of the baffle 6.

[0023] Reference Figure 4As shown in this embodiment: Slide grooves 13 are provided on both sides of the inner cavity of the movable groove 10, and sliders 14 are fixedly connected to both sides of the energy storage block 12. The surface of the sliders 14 is slidably connected to the inside of the slide grooves 13. By providing slide grooves 13 on both sides of the inner cavity of the movable groove 10 and fixing sliders 14 to both sides of the energy storage block 12, the surface of the sliders 14 is slidably connected to the inside of the slide grooves 13. When the energy storage block 12 moves under the elastic force of the energy storage spring 11, the sliders 14 can slide stably within the slide grooves 13, providing guidance for the movement of the energy storage block 12. This further ensures that the energy storage block 12 can slide accurately and smoothly into the slot 8, improving the stability and reliability of the device operation.

[0024] Reference Figure 3 As shown in this embodiment: both ends of the inner cavity of the moving groove 18 are provided with limiting grooves 15, and both ends of the moving block 4 are fixedly connected with limiting blocks 16. The surface of the limiting block 16 is slidably connected to the inside of the limiting groove 15. The cooperation between the limiting groove 15 and the limiting block 16 can prevent the moving block 4 from shifting position during the movement process, and ensure the stability of the moving block 4 sliding inside the moving groove 18.

[0025] Reference Figure 1 As shown in this embodiment, the baffle 6 is made of a transparent material. By using the baffle 6 made of a transparent material, the user can clearly observe the operation inside the monitoring panel 1.

[0026] Reference Figure 3 As shown in this embodiment: a thrust spring 17 is fixedly connected to one side of the moving block 4. One side of the thrust spring 17 is fixedly connected to one side of the inner cavity of the moving groove 18. By setting the thrust spring 17, the moving block 4 can be pushed. When the baffle 6 is released from its fixed position, the thrust spring 17 will drive the moving block 4 to reset through the pushing action, thereby driving the baffle 6 to move, which makes it convenient for staff to observe and use the monitoring instrument panel 1.

[0027] Working principle: By pressing down on the energy storage block 12, the operator moves the L-shaped rod 5. The L-shaped rod 5 causes the baffle 6 to move within the moving groove 18 inside the fixed plate 3. When both baffles 6 completely block the front end of the monitoring panel 1, the operator can release the energy storage block 12. The energy storage block 12, through the elastic force of the energy storage spring 11, will insert itself into the slot 8 at the top of the extension plate 7, fixing the position of the baffle 6 and thus preventing the use of the online monitoring device for backfill soil compaction. In case of accidental touch of the monitoring instrument panel 1, resulting in data errors, the online monitoring device for backfill soil compaction effectively improves the practicality of use. By setting the surface of the energy storage block 12 to slide in the interior of the slot 8, the external shape of the energy storage block 12 matches the internal shape of the slot 8. When the energy storage block 12 is subjected to the elastic force of the energy storage spring 11, the energy storage block 12 can slide stably and smoothly into the slot 8, ensuring the firm fixation of the baffle 6. By opening sliding grooves on both sides of the inner cavity of the movable groove 10, 13, and sliders 14 are fixedly connected to both sides of the energy storage block 12, so that the surface of the slider 14 is slidably connected to the inside of the groove 13. When the energy storage block 12 moves under the elastic force of the energy storage spring 11, the slider 14 can slide stably in the groove 13, providing guidance for the movement of the energy storage block 12, further ensuring that the energy storage block 12 can slide accurately and smoothly into the slot 8, improving the stability and reliability of the device operation. The cooperation between the limiting groove 15 and the limiting block 16 can prevent the moving block 4 from shifting position during the movement, ensuring the stability of the moving block 4 sliding in the moving groove 18. By using the baffle 6 made of a transparent material, the user can clearly observe the operation inside the monitoring panel 1. By setting the thrust spring 17, the moving block 4 can be pushed. When the baffle 6 is released, the thrust spring 17 will drive the moving block 4 to reset through the thrust, thereby driving the baffle 6 to move, which makes it convenient for the staff to observe and use the monitoring panel 1.
