[0002] During oilfield development, construction teams and related professionals often remain on-site for extended periods of time during oilfield testing and maintenance. Besides powering various machinery during construction, workers also need to maintain electricity for their daily needs. However, since most oilfields are located outdoors and have a single power source, domestic electricity is typically supplied by connecting a cable from the wellsite transformer distribution box to the living area to meet the staff's daily needs.

[0003] Safety and environmental protection requirements dictate that cables at well sites should be installed at least 2.5 meters above the ground, or buried at a depth of at least 0.3 meters. However, in practice, due to the lack of suitable cable support systems for well repair sites, trenching and burial are commonly used. This requires multiple steps, including excavation, formwork support, and burial. This results in a relatively long construction period, and the cables must be excavated at the end of the project, further extending the construction time. Furthermore, underground cables are difficult to maintain. Any cable failure requires re-excavation for inspection and maintenance, increasing repair costs. Utility Model Content

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] Example 1:

[0025] like Figure 1 、 Figure 2 and Figure 3 As shown, it includes a disc-shaped base 1, the top of the base 1 is threadedly connected to a lower support tube 2, the interior of the lower support tube 2 is divided into three sections: upper, middle and lower, and the inner diameter gradually increases from top to bottom, the inner walls of the upper and middle sections of the lower support tube 2 are provided with threads, the inner side of the lower support tube 2 is sleeved with an upper support rod 3, the bottom end of the upper support rod 3 is fixedly connected to a threaded column 4, the threaded column 4 cooperates with the thread of the upper section of the lower support tube 2, the bottom end of the threaded column 4 is fixedly connected to a locking block 5, and the cross-section of the locking block 5 is polygonal, the middle section of the lower support tube 2 is threadedly connected to a limiting block 6, the top of the limiting block 6 is provided with a limiting groove 7, the limiting groove 7 matches the locking block 5, and the top of the upper support rod 3 is fixedly connected to a clamp assembly 8.

[0026] The lower support tube 2 limits the position of the locking block 5 and the threaded column 4 through a three-section design. The inner diameter of the lower section is larger to prevent the locking block 5 from colliding with the inner wall of the pipe and damaging the thread when entering the lower support tube 2. The inner diameter of the upper section is smaller than that of the lower section to ensure that the threaded column 4 does not collide with the lower support tube 2 during the threading process of reaching the upper section of the lower support tube 2.

[0027] The locking block 5 cooperates with the limiting block 6 through the limiting groove 7 , and the torque is transmitted through the locking block 5 , so as to facilitate fixing the limiting block 6 on the thread of the middle section of the lower support tube 2 .

[0028] Example 2:

[0029] Based on Example 1:

[0030] like Figure 4 As shown, a plurality of fixing holes 9 are provided on the top of the base 1 , and steel chisels 10 are inserted into the fixing holes 9 .

[0031] The base 1 is fixed to the ground by a steel chisel 10 to maintain stable support of the base 1 and prevent the base 1 from tilting due to external forces and dragging the cable to cause unnecessary losses.

[0032] The steel drill 10 has a V-shaped structure, and one end is longer than the other end. The long end of the steel drill 10 is inserted into the ground, and the short end is extended into the fixing hole 9 to clamp the base 1 to fix the base 1. Both ends of the steel drill 10 are conical, and the conical design makes it easy to break the soil and insert into the ground.

[0033] After both ends of the V-shaped steel drill 10 are inserted into the ground, a triangular protrusion will remain on the ground. The staff can quickly pull the steel drill 10 out of the ground through the protrusion, which is convenient for disassembly of the device.

[0034] Example 3:

[0035] Based on Example 1:

[0036] like Figure 3 As shown, the thread of the middle section of the lower support tube 2 is arranged on the inner wall away from the upper section, leaving sufficient space for adjusting the height of the entire bracket.

[0037] The top end of the lower support tube 2 is threadedly connected with a dust cover 11, and the upper support rod 3 passes through the dust cover 11. The dust cover 11 is used to prevent debris from entering the lower support tube 2 and affecting the adjustment of the length of the device. At the same time, the dust cover 11 also fixes the upper support rod 3 to prevent the upper support rod 3 from shaking and affecting the stability of the device.

[0038] like Figure 2 and Figure 5 As shown, a hemispherical fixing protrusion 12 is fixedly connected to the side wall of the locking block 5 , and a groove 13 is opened on the side wall of the limiting groove 7 , and the groove 13 matches the fixing protrusion 12 .

[0039] The fixing protrusion 12 and the groove 13 can make the connection between the locking block 5 and the limit block 6 more stable. At the same time, the hemispherical fixing protrusion 12 can be disengaged from the groove 13 under the influence of external force, which not only ensures the stable connection between the locking block 5 and the limit block 6 but also maintains the mobility between the two parts.

[0040] Example 4:

[0041] Based on Example 1:

[0042] like Figure 6 As shown, the clamp assembly 8 includes an arc-shaped plate 14 threadedly connected to the lower support tube 2, an arc-shaped buckle 15 is provided above the arc-shaped plate 14, and the concave surfaces of the arc-shaped plate 14 and the arc-shaped buckle 15 are opposite to each other, for accommodating cables, and buffer rubber 16 is fixedly connected to the opposite concave surfaces of the arc-shaped plate 14 and the arc-shaped buckle 15, which improves the service life of the cable, and the arc-shaped plate 14 and the arc-shaped buckle 15 are fixed by bolts on both sides.

[0043] The arrangement of the arc-shaped plate 14 and the arc-shaped buckle 15 can clamp the cable, thereby preventing the cable from being dislodged from the clamp assembly 8 due to external forces such as strong winds.

[0044] At the same time, the buffer rubber 16 can fill the gaps between the cable and the arc-shaped plate 14 and the arc-shaped buckle 15, thereby preventing the cable from rubbing against the two and thus reducing the service life of the cable.

[0045] The temporary cable installation bracket provided in this application is designed to address numerous issues with conventional cable installation methods at oilfield well repair sites. In practical applications, the bracket enables cables to be installed high in the air, eliminating the need for trench digging, significantly reducing cable installation time and significantly improving work efficiency.

[0046] Furthermore, by installing the cables in the air, the risk of them being crushed or damaged by ground objects is effectively avoided, significantly improving electrical safety. This high-altitude installation also facilitates subsequent maintenance and management. Since the cables are no longer buried underground, if a fault occurs, maintenance personnel can quickly locate and resolve the issue without the tedious excavation work. This not only saves time and labor costs, but also ensures the normal operation of equipment and the smooth progress of construction.

[0047] Directions:

[0048] Step 1: Insert the locking block 5 into the limiting groove 7 on the surface of the limiting block 6, so that the fixing protrusion 12 fits with the groove 13, and the locking block 5 is connected to the upper support rod 3;

[0049] Step 2: Insert the upper support rod 3 into the lower support tube 2 from the bottom and extend it from the top. When the limit block 6 contacts the thread of the middle section of the lower support tube 2, rotate the upper support rod 3 so that the limit block 6 is threadedly connected to the lower support tube 2.

[0050] Step 3: Pass the dust cover 11 through the upper support rod 3 and fix it on the top of the lower support tube 2;

[0051] Step 4: Fix the clamp assembly 8 on the upper support rod 3, and put the cable into the groove between the arc plate 14 and the arc buckle 15, and then fix the arc plate 14 and the arc buckle 15 with bolts;

[0052] Step 5: Connect the lower support tube 2 to the base 1, and stand the device upright. Insert the short end of the steel chisel 10 into the fixing hole 9 and the long end into the ground fixing base 1.

[0053] When you need to adjust the stand height:

[0054] Step 1: The operator pulls the upper support rod 3 upwards, causing the fixing protrusion 12 to slightly deform and come out of the groove 13, and the locking block 5 to disengage from the limiting groove 7 and be unlocked;

[0055] Step 2: The operator lifts the upper support rod 3 upward until the threaded column 4 contacts the thread of the upper section of the lower support tube 2, and then rotates the upper support rod 3 to screw the threaded column 4 into the upper section of the lower support tube 2 to complete the fixation.

[0056] When adjusting the height of the bracket, if there is a cable between the arc-shaped plate 14 and the arc-shaped buckle 15, the cable needs to be taken out before adjusting the height.
