Description

Technical Field

[0001] This application relates to the field of mud testing, and in particular to an automated device for detecting the specific gravity of mud used in diaphragm walls. Background Technology

[0002] During the construction of diaphragm walls, it is usually necessary to test the specific gravity of the slurry. This is primarily because if the slurry's specific gravity is too low, it may lead to safety accidents such as trench wall instability and collapse. Conversely, slurry with an excessively high specific gravity may increase the load and wear on construction equipment, reducing its lifespan. Therefore, by testing the slurry's specific gravity, potential safety hazards can be identified and corrected in a timely manner, ensuring the smooth progress of the construction process.

[0003] When constructing a diaphragm wall, the procedure for testing the specific gravity of the slurry is usually to place a slurry specific gravity sensor in the slurry tank and directly measure the specific gravity of the slurry in the tank. The data obtained from the slurry specific gravity test is then observed and recorded by the staff using a corresponding connected testing instrument.

[0004] Regarding the aforementioned technologies, the data detected by the mud density sensor in the mud pit is not easy to observe intuitively, which makes it difficult to quickly adjust the mud density in the mud pit in a timely manner. Utility Model Content

[0005] To facilitate intuitive observation of the data after testing in the mud pit and to quickly adjust the mud specific gravity in the mud pit, this application provides an automated detection device for the specific gravity of diaphragm wall mud.

[0006] The automated detection device for the specific gravity of diaphragm wall slurry provided in this application adopts the following technical solution:

[0007] An automated detection device for the specific gravity of slurry in diaphragm walls includes a display module and a detection module. The detection module includes a detection mounting rod and a slurry specific gravity sensor. The slurry specific gravity sensor is installed on the detection mounting rod and is used to detect the specific gravity of the slurry in the slurry tank. The display module includes a display screen installed on the top of the slurry tank. The display screen is electrically connected to the slurry specific gravity sensor and is used to display the data detected by the slurry specific gravity sensor.

[0008] By adopting the above technical solution, after the detection rod is placed in the mud tank, the mud specific gravity sensor detects the specific gravity of the mud in the mud tank. The data detected by the mud specific gravity sensor is displayed on the screen, which makes it easy for the staff to observe the data after detection in the mud tank intuitively, and thus quickly adjust the specific gravity of the mud in the mud tank in a timely manner.

[0009] Optionally, it also includes a base plate installed on top of the mud pit, the display screen is rotatably mounted on the base plate, the display module also includes a rotating assembly, the rotating assembly includes a rotating motor, a rotating worm gear and a rotating worm, the rotating worm gear is coaxially fixedly mounted on the display screen, the rotating worm is rotatably mounted on the base plate and meshes with the rotating worm gear, and the rotating motor is used to drive the rotating worm to rotate.

[0010] By adopting the above technical solution, the base plate facilitates the stable display of detection data on the top of the mud tank. When the rotating motor drives the rotating worm gear to rotate, the rotating worm wheel drives the display screen to rotate together, thereby realizing the adjustment of the rotation angle of the display screen. This allows for intuitive observation of the data displayed on the display screen from different angles, making it highly applicable. Furthermore, the self-locking effect between the rotating worm wheel and the rotating worm gear helps to ensure the stability of the position of the display screen after rotation.

[0011] Optionally, the rotating assembly further includes a protective cover mounted on the base plate, the protective cover enclosing the rotating worm gear and the rotating worm.

[0012] By adopting the above technical solution, the protective cover provides protection during the transmission between the rotating worm gear and the rotating worm, thus ensuring the transmission stability between them.

[0013] Optionally, the detection mounting rod is vertically arranged, and multiple mud specific gravity sensors are arranged along the length of the detection mounting rod, each of which is electrically connected to the display screen.

[0014] By adopting the above technical solution, the setting of multiple mud specific gravity sensors facilitates the simultaneous detection of the specific gravity of mud at different depths in the mud pit, which helps to further ensure the accuracy of mud specific gravity detection in the mud pit.

[0015] Optionally, the detection mounting rod is slidably fitted with sliding mounting blocks that correspond one-to-one with the mud density sensors, and the sliding mounting blocks are fixedly installed on the detection mounting rod by bolts.

[0016] By adopting the above technical solution, the sliding mounting block is slidable, causing the specific gravity sensor to slide to different positions on the detection mounting rod. This allows for adjustment of the position of the mud specific gravity sensor, making it easier for the mud specific gravity sensor to detect the specific gravity of mud at different depths in the mud tank. This method has strong applicability.

[0017] Optionally, the base plate is provided with a lifting assembly for driving the detection mounting rod to rise and fall. The lifting assembly includes a lifting screw, a lifting drive component, a lifting guide rod, and a lifting fixing block. The lifting screw is vertically and rotatably mounted on the top of the base plate. The lifting drive component is used to drive the lifting screw to rotate. The lifting screw passes through the lifting fixing block and is threadedly engaged with the lifting fixing block. The lifting guide rod is vertically and fixedly mounted on the top of the base plate. The lifting guide rod passes through the lifting fixing block and is slidably engaged with the lifting fixing block. The detection mounting rod is fixedly mounted on the lifting fixing block.

[0018] By adopting the above technical solution, when the lifting drive component drives the lifting screw to rotate, the lifting fixed block moves vertically due to its threaded engagement with the lifting screw and the limiting action of the lifting guide rod, thereby driving the detection mounting rod to adjust its height position. This facilitates the mud specific gravity sensor to quickly detect mud at different depths in the mud tank. Furthermore, the lifting screw remains outside the mud tank during the lifting and lowering process of the detection mounting rod, ensuring the stability of the detection mounting rod during height adjustment.

[0019] Optionally, the lifting drive component includes a lifting motor, a lifting worm gear, and a lifting worm. The lifting worm gear is coaxially fixedly installed on the lifting screw, and the lifting worm is rotatably installed on the base plate and meshes with the lifting worm gear. The lifting motor is used to drive the lifting worm to rotate.

[0020] By adopting the above technical solution, when the lifting motor drives the lifting worm to rotate, the lifting worm wheel drives the lifting screw to rotate around its own axis. The self-locking effect between the lifting worm wheel and the lifting worm helps to ensure the stability of the position of the lifting screw after rotation.

[0021] Optionally, a lifting limit plate is fixedly installed on the top of the lifting screw and / or lifting guide rod.

[0022] By adopting the above technical solution, the lifting limit plate is set to limit the movement of the lifting fixed block in the vertical direction, making it difficult for the lifting fixed block to detach from the lifting screw when it moves in the vertical direction, thus further ensuring the stability of the lifting fixed block during movement.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. After placing the detection rod into the mud tank, the mud specific gravity sensor detects the specific gravity of the mud in the mud tank. The data detected by the mud specific gravity sensor is displayed on the screen, which makes it easy for the staff to intuitively observe the data after detection in the mud tank, and thus quickly adjust the specific gravity of the mud in the mud tank in a timely manner.

[0025] 2. When the rotating motor drives the rotating worm gear to rotate, the rotating worm wheel drives the display screen to rotate together, thereby realizing the adjustment of the rotation angle of the display screen. This makes it easy to observe the data displayed on the display screen intuitively from different angles, and it has strong applicability.

[0026] 3. When the lifting drive unit drives the lifting screw to rotate, the lifting fixed block, due to its threaded engagement with the lifting screw and the limiting effect of the lifting guide rod, drives the detection mounting rod to adjust its height position, thereby facilitating the mud specific gravity sensor to quickly detect mud at different depths in the mud tank.

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] This application discloses an automated device for detecting the specific gravity of slurry in diaphragm walls. (Refer to...) Figure 1 The automated detection device for the specific gravity of slurry in diaphragm walls includes a base plate 1, a display module, and a detection module. The base plate 1 is fixedly installed on the top of the slurry tank. The detection module is used to detect the specific gravity of the slurry in the slurry tank, and the display module is used to display the specific gravity data of the slurry detected by the detection module.

[0034] Reference Figure 2 and Figure 3Specifically, the display module includes a display screen 2 and a rotating assembly. The display screen 2 displays the mud specific gravity data detected by the detection module. A vertically mounted fixing rod 3 is fixedly installed at the bottom of the display screen 2, and the fixing rod 3 is rotatably mounted on the base plate 1. The rotating assembly includes a rotating motor 4, a rotating worm gear 5, and a rotating worm 6. The rotating worm gear 5 is coaxially fixedly installed on the fixing rod 3, and the rotating worm 6 is rotatably mounted on the base plate 1 and meshes with the rotating worm gear 5. When the rotating worm 6 is rotatably installed, the rotating worm gear 5 drives the fixing rod 3 and the display screen 2 to rotate together, so that the display screen 2 can display the mud specific gravity data at different angles.

[0035] Reference Figure 1 and Figure 3 To ensure the meshing stability between the rotating worm 6 and the rotating worm wheel 5, the rotating assembly also includes a protective cover 7. The protective cover 7 covers the rotating worm wheel 5 and the rotating worm 6 to protect them. The rotating motor 4 is mounted on the outside of the protective cover 7, and its output end extends into the protective cover 7 and rotates in cooperation with it. The rotating worm 6 is fixedly installed on the output end of the rotating motor 4 so that the rotating motor 4 drives the rotating worm 6 to rotate.

[0036] Reference Figure 2 and Figure 3 The detection module includes a detection mounting rod 8, a mud specific gravity sensor 9, and a lifting assembly. The lifting assembly includes a lifting screw 10, a lifting drive component, a lifting guide rod 11, and a lifting fixing block 12. The lifting screw 10 is vertically rotatably mounted on the top of the base plate 1, and the lifting guide rod 11 is vertically fixedly mounted on the top of the base plate 1. The lifting screw 10 passes through the lifting fixing block 12 and is threadedly engaged with the lifting fixing block 12. The lifting guide rod 11 passes through the lifting fixing block 12 and slides through the lifting fixing block 12, so that when the lifting screw 10 rotates, the lifting fixing block 12 moves vertically due to the threaded engagement with the lifting screw 10 and the limiting action of the lifting guide rod 11.

[0037] Reference Figure 1 and Figure 3 The lifting drive component includes a lifting motor 13, a lifting worm gear 14, and a lifting worm 15. The lifting worm gear 14 is coaxially fixedly installed on the lifting screw 10 and located near the bottom of the lifting screw 10. The lifting worm 15 is rotatably installed on the base plate 1 and meshes with the lifting worm gear 14. The base plate 1 is provided with a protective cover 16 that covers the lifting worm gear 14 and the lifting worm 15 to protect them during meshing transmission. The output end of the lifting motor 13 extends into the protective cover 16 and rotatably engages with the protective cover 16. The rotating worm 6 is fixedly installed on the output end of the lifting motor 13 so that the lifting motor 13 drives the lifting worm 15 to rotate.

[0038] Reference Figure 2 and Figure 3 The detection mounting rod 8 is fixedly installed on the lifting fixing block 12 so that the detection mounting rod 8 can be adjusted vertically together with the lifting fixing block 12. To further ensure the stability of the detection mounting rod 8 during vertical adjustment, i.e., height adjustment, and to prevent the detection mounting rod 8 from falling off the lifting screw 10, a lifting limit plate 17 is fixedly installed on the top of the lifting screw 10, and the top of the lifting guide rod 11 is also fixedly installed on the lifting limit plate 17, so that the lifting limit plate 17 can limit the movement of the lifting fixing block 12.

[0039] Reference Figure 3 The detection mounting rod 8 is slidably fitted with several sliding mounting blocks 18 along its own length. Each sliding mounting block 18 has a vertically penetrating sliding mounting groove 19. The detection mounting rod 8 is slidably fitted into the sliding mounting groove 19. The sliding mounting blocks 18 are fixedly installed on the detection mounting rod 8 by bolts that are threaded to themselves and abut against the detection mounting rod 8, so as to realize the adjustment of the sliding mounting blocks 18 along the length of the detection mounting rod 8.

[0040] Continue to refer to Figure 3 Multiple mud specific gravity sensors 9 are provided in a one-to-one correspondence with sliding mounting blocks 18. Each mud specific gravity sensor 9 is fixedly installed on each sliding mounting block 18, so that each mud specific gravity sensor 9 can be adjusted along the length direction of the detection mounting rod 8 together with the sliding mounting block 18. Each mud specific gravity sensor 9 is electrically connected to the display screen 2, so that after the detection mounting rod 8 is placed in the mud tank, each mud specific gravity sensor 9 can detect the mud specific gravity in the mud tank. The display screen 2 can display the detection data of each mud specific gravity sensor 9. The setting of the sliding mounting block 18 driving the mud specific gravity sensor 9 to adjust along the length direction of the detection mounting rod 8 facilitates the detection of mud specific gravity at different depths in the mud tank by the mud specific gravity sensor 9, and has strong applicability.

[0041] The implementation principle of the automated mud specific gravity detection device for underground continuous wall in this embodiment is as follows: When detecting the mud specific gravity in the mud tank, the detection installation rod 8 is first moved vertically to place it in the mud tank. Then, the mud specific gravity sensor 9 installed on the detection installation rod 8 is used to detect the mud specific gravity in the mud tank. The data detected by the mud specific gravity sensor 9 is displayed on the display screen 2, so that the staff can intuitively observe the data after detection in the mud tank, and thus quickly adjust the mud specific gravity in the mud tank in a timely manner.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
