Description

Technical Field

[0001] This utility model relates to a cable trench earthquake collapse simulation system, belonging to the field of disaster simulation technology. Background Technology

[0002] Cable trenches are the protective structures for cable installations, widely used in infrastructure construction for power, telecommunications, and rail transportation, for laying and protecting cables. However, in actual engineering projects, due to complex geological conditions, improper construction, external loads, or natural disasters (such as rainstorms and earthquakes), cable trenches may collapse, causing cable damage, power outages, and even casualties. Currently, there is no readily available, safe, and low-cost method to simulate the mechanism of cable trench collapse, which fails to meet the needs of engineering training and education. Therefore, there is a need to develop a controllable and repeatable cable trench collapse simulation demonstration device. This device can help construction and management personnel understand the risks of cable trench collapse and improve their safety awareness. Utility Model Content

Detailed Implementation

[0027] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Example 1

[0029] like Figures 1-6 As shown, a cable trench earthquake collapse simulation system includes a demonstration device and a power device, wherein the demonstration device is connected to the power device and the power device is capable of driving the demonstration device to move.

[0030] The demonstration device includes a fixed support and at least two movable plates. The fixed support and the movable plates are connected by hinges. Driven by a power unit, the movable plates can tilt, move, or deform to different degrees, thereby simulating the process of cable trenches becoming unstable and collapsing under earthquakes or other complex external forces.

[0031] The power unit includes an upper push rod assembly 2 and a lower push rod assembly 1. The upper push rod assembly 2 and the lower push rod assembly 1 are respectively connected to different movable plates, and the upper push rod assembly 2 and the lower push rod assembly 1 can drive the movable plates connected to them to move.

[0032] In this embodiment, three movable sections are provided: a first section 3, a second section 4, and a third section 5. The upper push rod assembly 2 is connected to the first section 3, and the lower push rod assembly 1 is connected to the third section 5. A track is provided between the first section 3 and the second section 4, allowing the first section 3 to move and thus move the second section 4. During the simulation, the upper push rod assembly 2 and the lower push rod assembly 1 can move the first section 3, the second section 4, and the third section 5 by extending and retracting the push rods, thus demonstrating the collapse effect.

[0033] In this embodiment, the first plate 3 and the second plate 4 are connected by a track: the track is a linear slide rail made of metal, used to ensure that the second plate 4 can slide smoothly under the action of the first plate 3. When the upper push rod assembly 2 pushes the first plate 3, the movement of the first plate 3 is transmitted to the second plate 4 through the track structure, thereby realizing the linkage displacement between the two. The third plate 5 is connected to the lower push rod assembly 1, can rotate around a hinge, and tilt within a certain range, cooperating with the movement of the first plate 3 and the second plate 4 to simulate the collapse process.

[0034] Reference Figure 1-6 The fixed support consists of several columns, crossbeams, and side beams, forming a stable frame structure capable of withstanding the reaction forces generated by the upper push rod assembly 2 and the lower push rod assembly 1 during movement. The upper push rod assembly 2 is fixed to the top of the fixed support; the lower push rod assembly 1 is fixed to the bottom of one side of the fixed support.

[0035] The lower push rod assembly 1 includes a push rod 11, a push rod bracket 12, and a housing 13. The push rod bracket 12 secures the push rod 11, and the housing 13 houses the push rod 11 and the push rod bracket 12, protecting both. The lower push rod assembly 1 can be used to push the third plate 5 vertically or at an angle. The push rod bracket 12 is fixed to the side of the fixed bracket to support and position the lower push rod assembly 1, ensuring stability of the push rod 11 when driving the third plate 5. The housing 13 is fixed to the outside of the push rod bracket 12 to protect the internal structure of the lower push rod assembly 1 and prevent external debris or dust from entering and affecting the push rod's movement. One end of the push rod 11 is connected to the bottom of the third plate 5.

[0036] The bottom of the third section 5 is connected to the fixed support by a hinge. The third section 5 can be driven by the push rod 11 to tilt inward along the hinge direction to simulate the heave, subsidence or displacement of the bottom or sidewall of the cable trench under the action of an earthquake.

[0037] The upper push rod assembly 2 includes a short arm 21, a long arm 22, a ball nut 24, a slide rail 25, a transverse push rod 26, a movable bracket 27, a vertical push rod 28, a zigzag buckle 29, and a slide rail platform 210. (See reference) Figure 6 One side of the short arm 21 is connected to the first plate 3, and the other side of the short arm 21 is provided with a long arm 22, which is connected to the other side of the vertical push rod 28. A spherical nut 24 is provided at the connection between the vertical push rod 28 and the long arm. The long arm 22 is fixed by a long arm bracket 23. The vertical push rod 28 is set in the movable bracket 27 by a U-shaped buckle 29. The combination of the short arm 21 and the long arm 22 can realize the telescopic mechanism. The long arm bracket 23 is used to fix the long arm 22 and ensure that it can maintain the movement trajectory of the fish hole during movement. The spherical nut 24 can ensure that the angle of the contact surface between the vertical push rod 28 and the long arm 22 is adaptive, avoiding excessive rigidity of the push connection, which may lead to jamming or local stress concentration.

[0038] The upper push rod assembly 2 is mounted on top of the fixed bracket via a slide rail 25. A slide rail platform 210 is provided on one side of the slide rail 25, and a movable bracket 27 is fixed on top of the slide rail platform 210 to ensure the stability of the movable bracket 27. The slide rail 25 is a long strip guide rail, and a transverse push rod 26 is also provided on one side of the slide rail 25. The transverse push rod 26 can drive the movable bracket 27 to move on top of the slide rail 25, and the left and right positions of the upper push rod assembly 2 on top of the fixed bracket can be changed by the transverse push rod 26.

[0039] The movement of the upper push rod assembly 2 can cause the first plate 3 to rotate and tilt along the hinge direction. When the first plate 3 is linked to the second plate 4 via the track connection, the second plate 4 will move along with the first plate 3. By adjusting the position of the upper push rod assembly 2 with the lateral push rod 26, the amplitude or direction of movement of the first plate 3 and the second plate 4 can be changed.

[0040] In the initial state, the first plate 3, the second plate 4, and the third plate 5 are on the same horizontal plane as the fixed support, and the lower push rod assembly 1 and the upper push rod assembly 2 can maintain the stability of each plate. When simulating the collapse of the cable trench due to an earthquake or other accident, the lower push rod assembly 1 is activated, which drives the third plate 5 to tilt via push rod 11, simulating the collapse of the sidewall of the cable trench caused by impact. The upper push rod assembly 2 is activated, and driven by the lateral push rod 26, it first adjusts its lateral position on the slide rail platform 210, and then drives the long arm 22 to drive the short arm 21 to guide the first plate 3 to move via the vertical push rod 28. When the first plate 3 moves, the second plate 4 connected by the track will also move accordingly, thus simulating the phenomenon of multiple plates moving and tearing against each other.

[0041] In this embodiment, the first section 3, the second section 4, and the third section after the simulated collapse can be reset by the drive of the lower push rod assembly 1 and the upper push rod assembly 2.

[0042] In this embodiment, the lower push rod assembly 1 and the lower push rod assembly 2 are controlled by a console. The console can be used in conjunction with other devices for linkage control, or it can be connected to a 220V power supply for control independently depending on the usage.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
