Description

Technical Field

[0001] This utility model relates to the field of cable protectors, and more particularly to a simple lightweight jumper cable protector. Background Technology

[0002] With the rapid development of modern urban infrastructure, industrial automation, and new energy fields, cables, as the core carriers of power transmission and signal control, face higher requirements for safety and reliability. Especially under complex operating conditions, cable joints, bends, and bridging points are prone to failure due to mechanical stress, environmental corrosion, or electromagnetic interference, becoming weak links in the cable network. According to industry statistics, approximately 35% of cable faults worldwide originate from joint protection failure, leading to power outages, signal interruptions, and high maintenance costs. However, traditional cable protectors often suffer from insufficient protection capabilities, complex installation and maintenance, and poor adaptability. Against this backdrop, cable protectors with bridging couplings have emerged.

[0003] The existing protector is made by stamping a steel plate into a large protrusion to protect the cable. The large protrusion occupies a large oil sleeve annulus. The inner walls of both ends of the protector are equipped with rubber to fix the cable. However, the rubber is prone to react with the liquid in the wellbore, causing the rubber to lose its elasticity and function. At the same time, the protector has a long axial length and a large rotation radius, which makes it poorly adaptable to the size of the wellbore oil sleeve annulus. Utility Model Content

[0004] To overcome the problems that existing crossover cable protectors have during use, such as the rubber extrusion at the cable clamping point causing the rubber to lose elasticity upon contact with the well fluid, resulting in the overall loss of cable protection function, and the fact that the diameter of the downhole crossover cable protector is often too large after installation, making it impossible to install a series of temperature and pressure acquisition equipment in thickened casing wells and casing supplement wells.

[0005] The technical solution of this utility model is: a simple lightweight jumper cable protector, including a middle section component, a first clamp component and a second clamp component movably connected to the middle section component, and a limiting component connected to the first clamp component and the second clamp component. The first clamp component and the second clamp component are arranged symmetrically about the vertical central axis of the middle section component.

[0006] The mid-section assembly includes a mid-section outer shell plate movably connected to the first clamp assembly and the second clamp assembly, a connecting arc strip connected to the mid-section outer shell plate, and a liquid filling assembly connected to the connecting arc strip;

[0007] The first clamp assembly includes a first fixing sleeve movably connected to the middle outer shell plate, a first connector connected to the first fixing sleeve, a first connecting groove formed on the first connector, and a first rotating plate assembly movably connected to the first connector.

[0008] The second clamp assembly includes a second fixing sleeve movably connected to the middle outer shell plate, a second connector connected to the second fixing sleeve, a second connecting groove formed on the second connector, and a second rotating plate assembly movably connected to the second connector.

[0009] Preferably, the liquid filling assembly includes a fixed liquid bag connected to the connecting arc strip, a liquid inlet pipe connected to the fixed liquid bag, a fixed valve connected to the liquid inlet pipe, and a connecting piece connected to the middle section outer shell plate.

[0010] Preferably, the first rotating plate assembly includes a first connecting rod movably connected to the first connecting head, a plurality of first connecting blocks connected to the first connecting rod, a first rotating plate movably connected to the first connecting rod, and a first mounting groove formed on the first fixed sleeve.

[0011] Preferably, the second rotating plate assembly includes a second connecting rod movably connected to the second connecting head, a plurality of second connecting blocks connected to the second connecting rod, a second rotating plate movably connected to the second connecting rod, and a second mounting groove formed on the second fixed sleeve.

[0012] Preferably, the limiting component includes a first fixing head connected to the second fixing sleeve, a telescopic component movably connected to the first fixing head, a second fixing head movably connected to the telescopic component, a limiting groove formed on the second fixing head, and a reset component connected between the first fixing head and the second fixing head.

[0013] Preferably, the telescopic assembly includes a rotating rod movably connected to the first fixed head, a rotating frame connected to the rotating rod, a telescopic bar movably connected to the rotating frame, and an adjustment groove formed on the telescopic bar.

[0014] Preferably, the reset assembly includes a reset spring connected to the first fixed head and the second fixed head respectively, and a fixing rod movably connected to the first fixed head and the second fixed head respectively.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model uses a steel plate with an external protrusion to allow the cable to pass through the coupling part, so that the steel plate is completely in contact with the coupling. Only the cable has a connecting arc protrusion, which makes the cross-coupling cable protector applicable to various sleeves. At the same time, it can also avoid cable damage caused by improper installation of the cross-coupling cable protector. In addition, the applicability of the cable protector can be improved by the first clamp assembly and the second clamp assembly that are movably connected to the middle section assembly.

[0017] 2. This utility model allows fluorinated liquid to enter the interior of the fixed liquid bag through the inlet pipe by opening the fixed valve. The expanding fixed liquid bag fills the gap between the middle outer shell plate and the cable, eliminating the problem of the rubber extruding the cable in existing cable protectors. At the same time, the physical properties of the fluorinated liquid make it almost non-reactive with any material, and its non-conductive and non-flammable properties also greatly improve the safety of this jumper cable protector. It eliminates the need for rubber extrusion at the cable fixing point, thereby reducing the chemical instability of the rubber in the liquid solution. Since the steel plate is in direct contact with the cable, the reliability of cable clamping is increased. Attached Figure Description

[0028] according to Figure 3 As shown, the liquid filling assembly includes a fixed liquid bag 103 connected to the connecting arc strip 102, an inlet pipe 104 connected to the fixed liquid bag 103, a fixed valve 105 connected to the inlet pipe 104, and a connecting piece 106 connected to the middle section outer shell plate 101.

[0029] It should be noted that by opening the fixed valve 105, the fluorinated liquid can enter the interior of the fixed liquid bag 103 through the inlet pipe 104, so that the expanding fixed liquid bag 103 can fill the gap between the middle shell plate 101 and the cable. At the same time, the physical properties of the fluorinated liquid make it almost non-reactive with any material, and its non-conductive and non-flammable physical properties can also greatly improve the safety of the jumper cable protector.

[0030] according to Figure 4 As shown, the first rotating plate assembly includes a first connecting rod 205 movably connected to the first connecting head 202, a plurality of first connecting blocks 206 connected to the first connecting rod 205, a first rotating plate 204 movably connected to the first connecting rod 205, and a first mounting groove 207 formed on the first fixed sleeve 201.

[0031] It should be noted that by connecting a number of first connecting blocks 206 to the first connecting rod 205, the first connecting rod 205 can be installed inside the first connector 202 without falling off.
