[0002] In temporary work scenes such as power engineering and construction, a large number of cables need to be temporarily erected to ensure the power supply of construction equipment or temporary lighting needs.

[0003] Traditional cable supports mostly adopt bolt fastening structures, and the disassembly process needs to use tools, which is time-consuming and difficult to meet the needs of quick layout and removal in temporary construction. At the same time, the clamping parts are mostly rigid materials, lack of buffer protection structure, and are easy to cause wear and tear to the cable sheath, which has safety hazards. In addition, the clamping force is difficult to accurately control, and too loose may cause the cable to fall off, and too tight may damage the internal structure of the cable.

[0004] The environment of temporary construction area is complex, and the personnel mobility is large. The cable is frequently stolen or maliciously damaged. The existing fixing device has no any anti-theft early warning mechanism, and cannot timely discover illegal theft behavior, which causes serious economic loss to the construction party. At the same time, there is no real-time monitoring of the cable placement state, and the abnormal conditions such as cable separation and dumping are difficult to be detected in time, which may cause safety accidents such as electric shock and equipment shutdown.

The fixing device 2 is arranged at the top of the triangular rod 1, and the fixing device 2 is used for clamping the cable, and the triangular rod 1 is supported on the ground. The triangular rod 1 comprises a mounting platform 1-7 and three groups of support rods, which are inserted into the ground in an outwardly inclined manner as a support structure of the mounting platform 1-7.

[0031] Any support rod comprises a connecting rod 1-1 and an adjusting rod 1-2, the connecting rod 1-1 is provided with an insertion groove, and the adjusting rod 1-2 is mounted in the insertion groove from bottom to top. The bottom end of the connecting rod 1-1 is provided with a limiting ring 1-3, which is limited on the outside of the adjusting rod 1-2 to prevent it from coming off. The height of the mounting platform 1-7 can be changed by adjusting the extension length of the adjusting rod 1-2, so as to achieve the purpose of flexible height adjustment.

[0032] The bottom end of the adjusting rod 1-2 is provided with a bottom touching foot 1-4, and the bottom end of the bottom touching foot 1-4 is provided with a conical head. The outer wall of the adjusting rod 1-2 is provided with a stepping plate 1-5 near the bottom touching foot 1-4, and the stepping plate 1-5 is used for stepping to assist the bottom touching foot 1-4 to be inserted into the ground. The upper part of the connecting rod 1-1 is sleeved with a locking buckle 1-6, and the locking buckle 1-6 is provided with a locking handle. When the locking handle is twisted, the bottom thereof is close to the outer wall of the adjusting rod 1-2, so as to realize the locking positioning of the adjusting rod 1-2.

[0033] The fixing device 2 comprises a base 2-1 and clamping plates, the base 2-1 is fixed on the mounting platform 1-7, the clamping plates comprise a fixed clamping plate 2-2 and a movable clamping plate 2-3, the fixed clamping plate 2-2 is arranged on the top left side of the base 2-1, and the movable clamping plate 2-3 is arranged on the top right side of the base 2-1.

[0034] A adjusting groove 2-4 is horizontally arranged on the right side of the base 2-1, a sliding block 2-5 is arranged on the bottom of the movable clamping plate 2-3, and the sliding block 2-5 is movably connected in the adjusting groove 2-4, so that the movable clamping plate 2-3 can move left and right in the adjusting groove 2-4.

[0035] A spring rod 2-6 is arranged in the adjusting groove 2-4, one end of the spring rod 2-6 is fixed on the sliding block 2-5, and the other end of the spring rod 2-6 extends outward to the right side of the base 2-1, and an abutting head is arranged on the end.

[0036] A rotary switch 2-7 is arranged on the right side of the base 2-1, an irregular protrusion is arranged on the rotary switch 2-7, one side of the protrusion abuts against the abutting head of the spring rod 2-6, when the protrusion rotates with the rotary switch 2-7, the spring rod 2-6 is pressed, and the spring rod 2-6 is retracted inward and synchronously pushes the movable clamping plate 2-3 to move left. When the rotary switch 2-7 is reversely rotated, the pressure on the spring rod 2-6 is released, the spring rod 2-6 returns to the initial position under the reset spring and drives the movable clamping plate 2-3 to move right. When the movable clamping plate 2-3 moves left, it is close to the fixed clamping plate 2-2, and the cable can be clamped, when the movable clamping plate 2-3 moves right, it is away from the fixed clamping plate 2-2, and the cable is released, so that the cable is convenient to take. The cable is clamped more stably through the adjustment of the clamping plate.

[0037] At least one pressure sensor 2-8 is arranged on the top surface of the base 2-1, and is used for monitoring the placement of the cable. A control box 3 is fixed on the right side of the base 2-1, and the pressure sensor 2-8 is electrically connected with the control box 3.

[0038] The control box 3 is provided with a control module and a communication module, and is connected with the background through a 4 / 5G network. When the cable is normally installed, the magnetic card key induction area is brushed once, at this time the cable electric control of the position is activated. When the cable is taken out, the magnetic card key induction area is brushed once, and the background records. At this time, the cable can be taken out without warning. If there is no card brushing step, it is determined that the cable is stolen, and the control box 3 can notify the background and send information to the mobile device of the designated personnel through the background. The notification methods include but are not limited to telephone, short message, app reminder or designated mailbox, which are used for anti-theft in temporary construction area.

[0039] In addition, the control box 3 is provided with a GPS / Beidou double positioning module, which can locate the position of the abnormal cable. If the cable is tilted or separated, it can be found at the first time, and the safety of the construction area is enhanced.

[0040] In addition, the fixing device 2 of the scheme can be placed in turn along the arrangement direction of the cable, and the control box 3 is provided with true and false. The false control box 3 is consistent with the true control box 3 in appearance. The true control box 3 is arranged at intervals to reduce the use cost, and the false control box 3 is arranged at the remaining positions to confuse.

[0041] The size of the fixed clamping plate 2-2 and the movable clamping plate 2-3 is the same, and the opposite surfaces of the fixed clamping plate 2-2 and the movable clamping plate 2-3 are provided with arc-shaped clamping grooves for clamping the cable.

[0042] The fixed clamping plate 2-2 and the movable clamping plate 2-3 are composed of a bottom plate and a mounting plate. The mounting plate is made of rubber or other flexible materials to reduce the wear on the cable. The bottom plate is symmetrically provided with a connection hole 2-9, and the mounting plate is also provided with a corresponding connection hole 2-9. A connection bolt 2-10 is installed in the connection hole 2-9. The connection bolt 2-10 is used to fix the bottom plate and the mounting plate together. The mounting plate can be replaced by disassembling it. When the mounting plate is excessively worn, it can be replaced more conveniently.

[0043] The bottom plate is provided with a butt joint groove 2-11 near the mounting plate, and the mounting plate is provided with an outwardly protruding butt joint foot 2-12 near the butt joint groove 2-11. The butt joint foot 2-12 is inserted into the butt joint groove 2-11 to assist the butt joint work of the mounting plate and the bottom plate, so that the connection is more tight and firm. The base 2-1, the fixed clamping plate 2-2 and the movable clamping plate 2-3 are all made of insulating materials.

[0044] The specific principle of the control box 3 is:

[0045] The inner cavity of the control box 3 is provided with a lithium battery power supply to provide stable power support for all electrically controlled components (such as control modules, communication modules, positioning modules, pressure sensors 2-8, control panels, etc.) in the box, ensuring continuous operation of the equipment. At the same time, the main body of the control box 3 adopts a waterproof shell, and the control panel also has a waterproof design, which can avoid short circuit damage to the power supply and electrically controlled components caused by wet and rainy environments in the construction site, and improve the environmental adaptability of the equipment.

[0046] The control box 3 receives the signal of the pressure sensor 2-8 through electrical connection and processes it by the internal control module. When the cable is placed between the clamps, the pressure sensor 2-8 on the top surface of the base 2-1 is subjected to pressure, generating a corresponding electrical signal and transmitting it to the control box 3. After receiving the signal, the control module determines that the cable is in a normal placement state, providing a basis for the subsequent anti-theft authentication function.

[0047] If the cable is separated from the clamps, the pressure sensor 2-8 has no pressure signal output, and the control module can assist in judging whether the equipment or cable has abnormality such as tilting or separation by combining other data (such as positioning information and pressure data changes).

[0048] With the cooperation of the magnetic card key sensing area and the control module, legal operation authentication and illegal behavior judgment are realized. After the cable is normally installed and the pressure sensor 2-8 detects the signal, the worker swipes the matching magnetic card key. The magnetic card key sensing area receives the sensing signal and transmits it to the control module, which activates the cable electric control system at this position. When the cable needs to be removed, the worker swipes the card again. The control module transmits the operation information to the communication module, which is synchronized to the background for recording, and then allows the cable to be removed without warning.

[0049] If the card swiping release step is not performed and the pressure sensor 2-8 signal suddenly disappears (or abnormally changes), the control module determines it as an illegal cable theft behavior according to the preset logic, and immediately triggers a warning instruction.

[0050] The communication module in the control box 3 establishes a stable connection with the background through 4 / 5G network, and undertakes the function of information interaction. When it is determined as an illegal theft behavior, the control module sends the warning instruction, device identification and other information to the communication module. The communication module uploads the information to the background through the 4 / 5G network. The background pushes the warning information to the mobile devices of the designated personnel in a preset way (phone, SMS, app reminder, designated mailbox, etc.), realizing rapid alarm. When the cable is legally removed, the communication module synchronously uploads the card swiping record, operation time and other information to the background, completing the operation trace.

[0051] The control box 3 is built-in with GPS / Beidou dual positioning module, realizing the position positioning of the device and cable. The positioning module receives the positioning signals of GPS and Beidou satellites in real time, calculates the accurate position information of the device, and transmits the position data to the control module in real time. When the cable is tilted, separated or has other position abnormalities, the control module combines the signal changes of the pressure sensor 2-8 and the position data of the positioning module to confirm the abnormal state, and uploads the abnormal position information to the background through the communication module. According to the received positioning information, the background quickly locks the position of the abnormal device, so that the staff can timely go to handle, and the safety of the construction area is improved.

[0052] Working principle:

[0053] The three sets of support rods are inserted into the ground at an outward inclination, and the geometric stability of the triangular structure provides reliable support for the top mounting platform 1-7, avoiding the problem of easy tilting of a single support point, and adapting to the complex ground environment of the temporary construction site.

[0054] Each set of support rods is composed of a connecting rod 1-1 and an adjusting rod 1-2. The adjusting rod 1-2 can move up and down along the insertion slot in the connecting rod 1-1. By changing the extension length of the adjusting rod 1-2, the height of the mounting platform 1-7 is adjusted synchronously to meet the height requirements of cable erection in different construction scenarios.

[0055] After adjusting to the target height, the locking handle of the upper locking buckle 1-6 of the connecting rod 1-1 is twisted to make the bottom of the locking buckle 1-6 fit the outer wall of the adjusting rod 1-2, and the position of the adjusting rod 1-2 is fixed by friction force to prevent height deviation. The conical head at the bottom of the adjusting rod 1-2 cooperates with the pedal 1-5, and the construction personnel can step on the pedal 1-5 to help the bottom foot 1-4 to insert into the ground, improving the installation efficiency and grounding stability of the support rod. The limiting ring 1-3 prevents the adjusting rod 1-2 from sliding out of the connecting rod 1-1.

[0056] The clamping plates of the fixing device 2 are divided into fixed clamping plates 2-2 and movable clamping plates 2-3. The slider 2-5 at the bottom of the movable clamping plate 2-3 is clamped in the adjusting slot 2-4 of the base 2-1 to provide guidance for lateral movement. One end of the spring rod 2-6 in the adjusting slot 2-4 is connected to the slider 2-5, and the other end is in contact with the protrusion of the knob switch 2-7 through the abutting head.

[0057] When the knob switch 2-7 is rotated, the irregular protrusion of the knob switch 2-7 presses the abutting head of the spring rod 2-6, causing the spring rod 2-6 to contract inward and push the movable clamping plate 2-3 to move leftward to approach the fixed clamping plate 2-2, and the cable is clamped by the arc-shaped clamping grooves on the opposite surfaces of the two clamping plates. Reverse rotation of the knob switch 2-7 releases the pressure of the protrusion on the spring rod 2-6, and the spring rod 2-6 and the movable clamping plate 2-3 are reset to the right under the action of the reset force of the spring, releasing the cable and realizing quick disassembly and assembly.

[0058] The mounting plate of the clamping plate is made of flexible materials such as rubber, which can reduce the wear and tear on the cable sheath during clamping. The mounting plate is precisely positioned by the butt joint foot 2-12 and the butt joint groove 2-11 of the bottom plate, and then fixed by the adapter bolt 2-10. When the mounting plate is severely worn, the bolt can be removed and the mounting plate can be replaced, reducing maintenance costs.

[0059] Through the cooperation of the pressure sensor 2-8 and the control box 3, the placement state of the cable can be monitored in real time. The principle is:

[0060] The pressure sensor 2-8 on the top surface of the base 2-1 is electrically connected to the control box 3. When the cable is placed between the clamping plates, the pressure sensor 2-8 detects the pressure signal and transmits it to the control box 3, which feeds back that the cable has been normally placed. If the cable is separated from the clamping plate, the pressure sensor 2-8 has no pressure signal, which can assist in determining that the cable state is abnormal.

[0061] The control panel of the control box 3 is provided with a magnetic card key sensing area. After the cable is normally installed, the card is swiped to activate the electric control system. When the cable is removed, the card must be swiped first. The background records legal operations to avoid false judgments. If the cable is forcibly removed without performing the card swiping removal step, the system determines it as an illegal theft, and the communication module in the control box 3 sends the warning information to the background through the 4 / 5G network. The background notifies designated personnel through telephone, SMS, etc.

[0062] The control box 3 is built-in GPS / Beidou dual positioning module. When the cable is tilted, separated or has other position abnormalities, the data of the pressure sensor 2-8 changes greatly, the positioning module obtains the abnormal position information in real time and synchronizes it to the background, which facilitates the staff to quickly locate and handle, and improves the safety of the construction area.

[0063] By arranging real and false control boxes 3, the anti-theft effect is ensured while the cost is reduced. The false control box 3 is identical in appearance to the real control box 3, which can form a visual deterrent to potential thieves. Only the real control box 3 with actual function is arranged at the key position, and the false control box 3 is placed at the remaining position, which reduces the number of core electric control components and controls the overall cost.

[0064] The base 2-1, the fixed clamping plate 2-2 and the movable clamping plate 2-3 are made of insulating materials, which can effectively avoid the risk of electric shock caused by device conduction during construction, and meet the electrical safety requirements of cable construction.
