Description

Technical Field

[0001] This utility model relates to the field of power engineering, and in particular to a horizontal displacement compensation device for the foundation of a power transmission tower suitable for complex terrain. Background Technology

[0002] In the field of power transmission, transmission towers, as crucial structures supporting high-voltage transmission lines, are of paramount importance in terms of stability and safety. Current transmission towers are typically installed on the ground, with displacement prevented by increasing foundation stability or choosing more stable foundation construction. However, due to complex terrain, variable soil conditions, and other external environmental factors, the foundations of transmission towers can experience horizontal displacement, easily leading to tower tilting or even collapse. This not only affects the tower's lifespan but also seriously threatens the safety and reliability of power transmission. Furthermore, once foundation displacement occurs, manual monitoring and repair are usually required, which is time-consuming, labor-intensive, increases maintenance difficulty, and is costly, posing safety risks.

[0003] Therefore, it is necessary to design a horizontal displacement compensation device for transmission tower foundations that can automatically compensate for displacement of the base of the transmission tower foundation when it is detected, so as to prevent the transmission tower from tilting or collapsing, improve the stability and safety of use, extend the service life, and be easy to use and suitable for complex terrain. Utility Model Content

[0004] To overcome the drawbacks of horizontal displacement of power transmission tower foundations caused by complex terrain, variable soil conditions, and other external environmental factors, which can easily lead to tower tilting or even collapse, affecting the service life of the tower and seriously threatening the safety and reliability of power transmission, this utility model provides a horizontal displacement compensation device for power transmission tower foundations that can automatically compensate for displacement of the base of the power transmission tower foundation when it is detected, preventing the power transmission tower from tilting or collapsing, improving the stability and safety of use, extending the service life, and is easy to use and suitable for complex terrain.

[0005] The technical solution of this utility model is as follows: a horizontal displacement compensation device for power transmission tower foundations suitable for complex terrain, comprising a base plate, a mounting plate, fixing nails, sleeves, sliding cylinders, locking pins, an adjustment component, and a pushing component. Sleeves are connected to the upper sides of both the left and right sides of the base plate, and sliding cylinders are slidably connected to each sleeve. The mounting plate is connected between the sliding cylinders. Fixing nails are connected to both the left and right sides of the base plate. Locking pins are locked onto the sleeves on opposite sides, and the locking pins are locked onto the sliding cylinders on the same side. An adjustment component is provided on the upper part of the mounting plate for adjusting to different terrains, and a pushing component is provided on the mounting plate for pushing back the power transmission tower foundation when it is displaced.

[0006] Furthermore, the mounting plate is L-shaped.

[0007] Furthermore, the lower part of the fixing pins is conical.

[0008] Furthermore, the locking pins are all equipped with anti-slip textures.

[0009] Furthermore, the adjustment assembly includes a connecting plate, a support base, and a first hydraulic cylinder. The upper part of the mounting plate is connected to two connecting plates on the left and right. The support base is placed on the ground and is located on the front side of the base plate. The middle part of the support base is also connected to two fixing nails on the left and right. The first hydraulic cylinder is rotatably connected to both the left and right sides of the support base. The extension and retraction ends of the first hydraulic cylinder are rotatably connected to the connecting plate on the same side.

[0010] Furthermore, the actuation component includes a second hydraulic cylinder, a pressure sensor, a compensation push plate, a mounting base, and a laser rangefinder. The upper rear side of the mounting plate is connected to two second hydraulic cylinders, and each of the second hydraulic cylinders is connected to a pressure sensor at its telescopic end. The pressure sensors are connected to the rear side of the pressure sensors via a compensation push plate. The upper side of the mounting plate is connected to two mounting bases, and each mounting base is connected to a laser rangefinder. The second hydraulic cylinders are electrically connected to the laser rangefinders.

[0011] Beneficial effects: 1. When the laser ranging sensor detects displacement, the second hydraulic cylinder is automatically activated, causing the compensation push plate to move and push the base of the power transmission tower to move for displacement compensation. The pressure sensor detects the thrust, so that when the displacement of the base of the power transmission tower is detected, it can automatically push back to compensate, preventing the power transmission tower from tilting or collapsing, improving the stability and safety of use, extending the service life, and making it convenient to use.

[0012] 2. When on flat ground, the first hydraulic cylinder is rotated to fix the support base to the ground. When on a slope, the mounting plate is pulled to move and then fixed. The first hydraulic cylinder is then rotated to fix the support base to the ground. This allows for adjustment of the position of the support base and the mounting plate to adapt to different terrains, making it easier to adjust and use according to different terrains, thus improving the versatility and adaptability of the device.

Detailed Implementation

[0018] 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.

[0019] A horizontal displacement compensation device for power transmission tower foundations suitable for complex terrain, such as Figures 1-4As shown, the system includes a base plate 1, a mounting plate 2, fixing nails 3, sleeves 7, sliding cylinders 8, locking pins 9, an adjustment assembly, and a pushing assembly. Sleeves 7 are connected to the upper sides of both the left and right sides of the base plate 1. Sliding cylinders 8 are slidably connected to each sleeve 7. The mounting plate 2, L-shaped for support, connects between the sliding cylinders 8. Fixing nails 3 are connected to both the left and right sides of the base plate 1. The lower parts of the fixing nails 3 are conical for easy insertion into the soil. Locking pins 9 are engaged on the opposite sides of the sleeves 7, and each locking pin 9 engages with a sliding cylinder 8 on the same side. The locking pins 9 have anti-slip textures to prevent slippage. The upper part of the mounting plate 2 has an adjustment assembly for adapting to different terrains. The adjustment assembly includes a connecting plate 4, a support base 5, and a first hydraulic cylinder 6. The upper part of the mounting plate 2 is connected to two connecting plates 4. The support base 5 is placed on the ground. Located on the front side of the base plate 1, the support base 5 is also connected to two left and right fixing nails 3 in the middle. The support base 5 is rotatably connected to the first hydraulic cylinder 6 on both the left and right sides. The telescopic ends of the first hydraulic cylinder 6 are rotatably connected to the connecting plate 4 on the same side. The mounting plate 2 is provided with a pushing assembly for pushing back when the power transmission tower base is displaced. The pushing assembly includes a second hydraulic cylinder 10, a pressure sensor 11, a compensation push plate 12, a mounting base 13, and a laser ranging sensor 14. The upper rear side of the mounting plate 2 is connected to two left and right second hydraulic cylinders 10. The telescopic ends of the second hydraulic cylinders 10 are connected to the pressure sensor 11. The compensation push plate 12 is connected between the rear sides of the pressure sensors 11. The upper side of the mounting plate 2 is connected to two left and right mounting bases 13. The mounting base 13 is connected to the laser ranging sensor 14. The second hydraulic cylinders 10 are electrically connected to the laser ranging sensor 14.

[0020] When displacement compensation of transmission tower foundations is required in complex terrain, this device can be used. Multiple connecting plates 4 are respectively in contact with the four sides of the transmission tower foundation base, causing the base plate 1 to contact the ground. The fixing nails 3 are inserted into the ground for fixation. The lower parts of the fixing nails 3 are conical for easy insertion into the soil. Then, depending on the terrain, on flat ground, the first hydraulic cylinder 6 is rotated to make the support seat 5 contact the ground for fixation. On a slope, the locking pin 9 is removed, and anti-slip texture is used for anti-slip. Next, the mounting plate 2 is pulled to move the sliding cylinder 8 along the sleeve 7. The mounting plate 2 is L-shaped for easy support. After moving to a suitable height, the locking pin 9 is engaged with the sleeve 7 and the sliding cylinder 8 for fixation. Then, the first hydraulic cylinder 6 is activated to rotate, making the support seat 5 contact the ground for fixation. After rotating to a suitable angle, the first hydraulic cylinder 6 is closed. This device is installed and fixed, allowing adjustment of the positions of the support base 5 and the mounting plate 2 to adapt to different terrains. This facilitates adjustments based on varying terrain conditions, improving the device's versatility and adaptability. When the laser ranging sensor 14 detects displacement of the transmission tower foundation, the second hydraulic cylinder 10 is automatically activated. The second hydraulic cylinder 10 drives the pressure sensor 11 and the compensation push plate 12 to move, causing the compensation push plate 12 to push the transmission tower foundation base back to its original position, thus achieving displacement compensation. The pressure sensor 11 detects the thrust, automatically performing counter-push compensation when displacement of the transmission tower foundation base is detected, preventing the transmission tower from tilting or collapsing, improving stability and safety, extending service life, and providing ease of use. When not in use, the device can be pulled out, allowing the base plate 1, the support base 5, and the fixing nails 3 to detach from the ground.
