Description

Technical Field

[0001] This utility model relates to a mechanical device for the construction of electro-osmotic drainage reinforcement of soft soil foundations, and more particularly to a titanium-based shape memory alloy electrode recovery and heating device for electro-osmotic drainage reinforcement of soft soil foundations. Background Technology

[0002] In the field of civil engineering, the treatment of soft soil foundations is a significant technical challenge. Due to their low strength, high compressibility, and poor permeability, soft soil foundations often lead to problems such as building settlement and road cracking in engineering practice. Traditional methods for treating soft soil foundations include preloading, deep mixing, and replacement. While these methods can improve the bearing capacity and stability of the foundation to some extent, they suffer from drawbacks such as long treatment cycles, high costs, and significant environmental impacts. With technological advancements, electroosmosis, as a novel soft soil foundation treatment technology, has gradually gained attention due to its rapid and efficient characteristics. Electroosmosis applies a direct current electric field, utilizing electroosmosis to accelerate the drainage of water from the soil, thereby achieving rapid consolidation and strength enhancement of the foundation.

[0003] In electroosmosis drainage consolidation technology, soil drainage efficiency and energy consumption are two key technical parameters. In traditional electroosmosis drainage consolidation processes, as the soil moisture content decreases, consolidation shrinkage occurs, leading to voids between the electrodes and the soil, increasing interfacial resistance, thus increasing energy consumption and weakening the drainage effect. Furthermore, the lack of effective drainage channels in the soil and the device hinders water flow, resulting in poor overall drainage. Additionally, the electrode materials used in traditional electroosmosis are mostly disposable and not reusable, increasing engineering costs and burdening the environment. These issues limit the application and promotion of electroosmosis in soft soil foundation treatment.

[0004] The soft soil foundation shape memory alloy adaptive electrode electro-osmotic drainage reinforcement technology utilizes a conductive sponge-air-filled composite structure between the alloy mesh and the soil. By leveraging the natural shrinkage characteristics of the alloy mesh and the controlled expansion of the conductive sponge, it ensures constant close contact between the titanium-based shape memory alloy mesh and the soil, improving the electro-osmotic drainage effect. After construction, the titanium-based shape memory alloy needs to be heated to restore its original shape for recycling. However, currently, there is a lack of supporting recycling heating equipment, and only general-purpose heating devices can be used. Because the conveying device is fixed, there is a distance between the electrodes and the heating tubes on the conveying device, limiting the heat transfer range of the heating tubes inside the device. This results in inconsistent recycling quality of the titanium-based shape memory alloy, affecting its subsequent reuse. Utility Model Content

[0005] To overcome the problem that the distance between the electrodes and the heating tubes on the fixed conveying device limits the heat transfer range of the heating tubes inside the heating device, affecting the heating effect of the electrodes and reducing the quality of the recycled material, this utility model provides a titanium-based shape memory alloy electrode recycling heating device for soft soil foundation electro-osmotic drainage reinforcement.

[0006] The technical solution of this utility model is as follows: a titanium-based shape memory alloy electrode recovery heating device for electro-osmotic drainage reinforcement of soft soil foundation, including a heating device body, a limiting support base and a heating component. A base is fixedly connected to the top of the heating device body, and a fixed support plate is movably connected inside the heating device body. A sensor and a control panel are provided on the front of the heating device body. The heating component is located inside the heating device body. A limiting support base is fixedly connected inside the heating device body. A first motor is provided on the back of the heating device body. A rotating connecting shaft is fixedly connected to the output end of the first motor. A first gear is fixedly connected to the front of the rotating connecting shaft. A rotating threaded rod is rotatably connected inside the heating device body. A second gear is rotatably connected to the outside of the rotating threaded rod. A fixed threaded cylinder is rotatably connected to the outside of the second gear. The fixed threaded cylinder is fixedly connected to the bottom of the fixed support plate.

[0007] Preferably, several telescopic rods are provided between the fixed support plate and the base to support the fixed support plate.

[0008] Preferably, a support mounting base is fixedly connected to the top of the fixed support plate, a sliding limit rod is fixedly connected inside the support mounting base, a sliding support block is slidably connected to the outside of the sliding limit rod, a pushing and squeezing ring is slidably connected to the outside of the sliding limit rod, and a return spring is fixedly connected between the pushing and squeezing ring and the fixed support plate.

[0009] Preferably, the support mounting base has a groove at the corresponding position of the sliding support block, and the sliding support block slides inside the groove.

[0010] Preferably, the compression ring is pushed into contact with the sliding support block, and two support mounting seats are provided, with the two support mounting seats symmetrically fixed on the top of the fixed support plate.

[0011] Preferably, the heating assembly includes a stainless steel electric heating tube, which is located at the bottom of the heating device body. A drive shaft is rotatably connected to the inner side of the sliding support block. A common heat-resistant tube is installed outside the drive shaft, and a heat-resistant ceramic is installed outside the common heat-resistant tube. A connecting mounting plate is fixedly connected to the back of the heating device body. A second motor is installed on the back of the connecting mounting plate. A first pulley is fixedly connected to the output end of the second motor. A second pulley is rotatably connected to the back of the heating device body. A drive belt is driven to the outside of the second pulley. The drive belt is driven to the outside of the first pulley. A drive connecting wheel is fixedly connected to the front of the first pulley. The drive connecting wheel rotates inside the heating device body.

[0012] Preferably, there are two transmission connecting wheels, and the two transmission connecting wheels are symmetrically rotated and connected inside the heating device body.

[0013] The beneficial effects of this utility model are as follows: Compared with the titanium-based shape memory alloy electrode recovery and heating device for electro-osmotic drainage reinforcement of soft soil foundation, the rotation of the rotating connecting shaft drives the meshing of the first gear and the second gear, which in turn drives the rotating threaded rod to rotate inside the heating device body. Through the threaded connection between the rotating threaded rod and the fixed threaded cylinder, the fixed support plate is pushed to rise and fall, thereby controlling the distance between the electrode and the stainless steel electric heating tube. This keeps the electrode within the effective heating range, ensuring effective heating when heating the electrode, improving the quality of recovery, and effectively preventing the problem of insufficient heating due to the distance between the electrode and the electric heating tube.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the technical solution of the present invention.

[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of a titanium-based shape memory alloy electrode recovery heating device for electro-osmotic drainage reinforcement of soft soil foundations. The device includes a heating device body 1, a limiting support base 801, and a heating assembly. A base 2 is fixedly connected to the top of the heating device body 1. A fixed support plate 3 is movably connected inside the heating device body 1. A sensor 4 and a control panel 5 are arranged on the front of the heating device body 1. The heating assembly is disposed inside the heating device body 1. The limiting support base 801 is fixedly connected inside the heating device body 1. A first motor 802 is arranged on the back of the heating device body 1. A rotating connecting shaft 803 is fixedly connected to the output end of the first motor 802. A first gear 804 is fixedly connected to the front of the rotating connecting shaft 803. A rotating threaded rod 805 is rotatably connected inside the heating device body 1. A second gear 806 is rotatably connected to the outside of the rotating threaded rod 805. A fixed threaded cylinder 807 is fixedly connected to the bottom of the fixed support plate 3. A sensor 4 is used to transmit signals, and a control panel 5 controls the equipment. The fixed support plate 3 supports the transmission components. The first motor 802 drives the rotating connecting shaft 803 to rotate inside the heating device body 1 under the limit of the limiting support seat 801. The rotation of the rotating connecting shaft 803 drives the meshing of the first gear 804 and the second gear 806, which in turn drives the rotating threaded rod 805 to rotate inside the heating device body 1. The threaded connection between the rotating threaded rod 805 and the fixed threaded cylinder 807 pushes the fixed support plate 3 to rise and fall. Several telescopic rods are provided between the fixed support plate 3 and the base 2. The telescopic rods support the fixed support plate 3 and limit its lifting.

[0022] Please see Figure 2 - Figure 3In this embodiment, a support mounting base 808 is fixedly connected to the top of the fixed support plate 3. A sliding limit rod 809 is fixedly connected inside the support mounting base 808. A sliding support block 810 is slidably connected to the outside of the sliding limit rod 809. A pushing and squeezing ring 811 is slidably connected to the outside of the sliding limit rod 809. A return spring 812 is fixedly connected between the pushing and squeezing ring 811 and the fixed support plate 3. The return spring 812 pushes the pushing and squeezing ring 811 to squeeze the sliding support block 810, thus squeezing the sliding support block 810 and supporting the mounting base 3. The support 808 has a groove at the corresponding position of the sliding support block 810. The sliding support block 810 slides inside the groove. The groove at the corresponding position of the sliding support block 810 inside the support mounting base 808 limits the sliding support block 810 when it slides inside the groove, pushing the compression ring 811 to contact the sliding support block 810. There are two support mounting bases 808, and the two support mounting bases 808 are symmetrically fixed on the top of the fixed support plate 3. The sliding support block 810 is pushed by the compression ring 811 contacting the sliding support block 810.

[0023] Please see Figure 4 - Figure 5 In this embodiment, the heating assembly includes a stainless steel electric heating tube 901, which is disposed at the bottom of the heating device body 1. A drive shaft 902 is rotatably connected to the inner side of the sliding support block 810. A common heat-resistant tube 903 is disposed on the outside of the drive shaft 902, and a heat-resistant ceramic 904 is disposed on the outside of the common heat-resistant tube 903. A connecting mounting plate 905 is fixedly connected to the back of the heating device body 1. A second motor 906 is disposed on the back of the connecting mounting plate 905. A first pulley 907 is fixedly connected to the output end of the second motor 906. A second pulley 908 is rotatably connected to the back of the heating device body 1. A drive belt 909 is drivenly connected to the outside of the second pulley 908. 9. A transmission connection is made to the outside of the first pulley 907. A transmission connecting wheel 910 is fixedly connected to the front of the first pulley 907. The transmission connecting wheel 910 rotates inside the heating device body 1. The first pulley 907 is driven to rotate by the second motor 906. The rotation of the first pulley 907, in turn, drives the second pulley 908 to rotate through the transmission belt 909. The rotation of the second pulley 908 and the first pulley 907 drives the transmission connecting wheel 910 to rotate. There are two transmission connecting wheels 910, and the two transmission connecting wheels 910 are symmetrically rotated and connected inside the heating device body 1. The two transmission connecting wheels 910 make them have a synchronous effect when rotating.

[0024] During operation, the electrode is placed on top of the heat-resistant ceramic 904 via the control panel 5. The first motor 802 drives the rotating connecting shaft 803 to rotate inside the heating device body 1, limited by the limiting support seat 801. The rotation of the rotating connecting shaft 803 drives the meshing of the first gear 804 and the second gear 806, causing the rotating threaded rod 805 to rotate inside the heating device body 1. The threaded connection between the rotating threaded rod 805 and the fixed threaded cylinder 807 pushes the fixed support plate 3 to rise and fall, controlling the distance between the electrode and the stainless steel electric heating tube 901. The second motor 906 drives the first pulley 907 to rotate, and the rotation of the first pulley 907 further... The transmission effect of the transmission belt 909 drives the second pulley 908 to rotate. The rotation of the second pulley 908 and the first pulley 907 drives the transmission connecting wheel 910 to rotate. There are two transmission connecting wheels 910, and the two transmission connecting wheels 910 are symmetrically connected inside the heating device body 1. The rotation of the transmission connecting wheel 910 sends the electrode into the heating device body 1. When the electrode enters the heating device body 1, the stainless steel electric heating tube 901 is heated by the control panel 5. The ordinary heat-resistant tube 903 and the heat-resistant ceramic 904 are made of heat-insulating material, which can prevent damage during heating. The shape memory alloy is restored to its original shape by heating.

[0025] Through the above steps, the first motor 802 drives the rotating connecting shaft 803 to rotate inside the heating device body 1 under the limitation of the limiting support seat 801. The rotation of the rotating connecting shaft 803 drives the meshing of the first gear 804 and the second gear 806, which in turn drives the rotating threaded rod 805 to rotate inside the heating device body 1. The threaded connection between the rotating threaded rod 805 and the fixed threaded cylinder 807 pushes the fixed support plate 3 to rise and fall. This allows the heating tube and the titanium-based memory alloy electrode to be adjusted to the appropriate position for titanium-based memory alloy electrode of different specifications. This solves the problem that the heating device for recovering titanium-based memory alloy electrodes for soft soil foundation electro-osmotic drainage reinforcement has a fixed conveying device, and there is a distance between the electrode and the heating tube on the conveying device. This results in a limited heat transfer range of the heating tube inside the heating device, which may not be able to effectively heat the electrode, affecting the heating effect and reducing the quality of the recovered product.

Those skilled in the art, based on the disclosure of this application, can add, reduce, or combine the disclosed technical features in the foregoing general description and / or specific embodiments (including examples) without departing from the constituent elements of the utility model, to form other technical solutions within the protection scope of this application.
