Description

Technical Field

[0001] The present invention relates to the technical field of power cables, in particular to an enhanced MPP power cable protection tube. Background Art

[0002] Power cables are key components used to transmit and distribute electric energy in power systems. Power cables are widely used in modern society, including urban distribution networks, industrial facilities, construction, and power transmission trunk lines. Cable protection tubes are important devices used to protect cables from external environmental damage to ensure safe and stable operation of cables and stability of power supply.

[0003] During the cable laying process, it is necessary to check that the cable appearance is intact and the insulation is good. Starting from the top of the cable reel, keep the cable loose to avoid excessive stretching. At the same time, attention should be paid to the order, model, and specifications of the cables during the laying process, and other environmental and geographical factors should also be considered. In addition, a cable protection tube structure is required for special laying sections or special conditions. When the cable may suffer mechanical damage, such as excavation, heavy load or other physical pressure or in harsh environmental conditions, such as chemical corrosion, humidity or extreme temperature, the use of cable protection tubes can provide necessary protection. Although the existing cable protection tubes are high in strength, they are easily damaged by collisions with hard objects during transportation and burial, which causes the protection tubes to crack and reduce the protection of the cables. For this reason, we have improved the above-mentioned existing technologies based on actual usage. Summary of the invention

[0004] The object of the present invention is to provide a reinforced MPP power cable protection tube to solve the problems raised in the above background technology.

[0011] Furthermore: two groups of clamping components with the same structure are symmetrically arranged on the outer end surfaces of the left locking block and the right locking block, and transverse grooves matching the clamping components are opened on the left locking block and the right locking block.

[0012] Further: the clamping assembly includes a trapezoidal block connected in the transverse groove, the inner end of the trapezoidal block is connected to a supporting vertical shaft, and the supporting vertical shaft is connected to a torsion spring, the outer end of the trapezoidal block is installed with a connecting shaft rod, the connecting shaft rod is connected to a limit block that does not contact the trapezoidal block, and the outer end of the limit block is connected to an arc-shaped clamping block.

[0013] Furthermore: four groups of cross beams with the same structure are evenly connected between the left guard plate and the left rear plate, and four groups of cross beams with the same structure are evenly connected between the right guard plate and the right rear plate, and each four groups of cross beams are connected by connecting ribs.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The protective body adopted in the present invention effectively protects the cable structure so that it will not be mechanically damaged during transportation or in specific environments. The cooperation of the crossbeam and connecting ribs arranged between the guard plates increases the mechanical strength of the protective body. At the same time, the two sets of locking blocks are combined through connecting screws and fixing bolts to facilitate disassembly and assembly, and the operation is simple to avoid misoperation by the staff.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The present invention provides a technical solution: an enhanced MPP power cable protection tube, comprising a cable structure 100, which is composed of a conductive core, an insulating layer, an armor layer, etc., and is an existing structure. The cable structure 100 penetrates the inner cavity of a protection body 200, and the cable structure 100 is protected by the protection body 200 in special sections, such as sections susceptible to mechanical damage or clamping of heavy objects;

[0025] The protection body 200 includes a left guard plate 201 and a right guard plate 202 symmetrically arranged with respect to the left guard plate 201, and a protective cover 203 is arranged on the rear end outer wall of the left guard plate 201 and the right guard plate 202, and reinforcing ribs 204 are evenly arranged on the front end outer wall of the left guard plate 201 and the right guard plate 202, and the left guard plate 201 and the right guard plate 202 are connected by a locking assembly 205, and the locking assembly 205 includes a left locking block 2051 and a right locking block 2052 movably connected thereto;

[0026] It should be noted that the bottom of the left guard plate 201 is rotatably connected to the bottom of the right guard plate 202, so the cable structure 100 can be conveniently placed into the protective body 200 by opening and closing. The protective cover 203 and the reinforcing ribs 204 can play a good supporting role and prevent damage to the cable structure 100 caused by foreign objects.

[0027] The rear ends of the protective cover 203 are respectively connected to a left rear plate 207 and a right rear plate 208, and the left rear plate 207 and the right rear plate 208 respectively correspond to the positions of the left guard plate 201 and the right guard plate 202, four groups of cross beams 206 with the same structure are evenly connected between the left guard plate 201 and the left rear plate 207, and four groups of cross beams 206 with the same structure are evenly connected between the right guard plate 202 and the right rear plate 208, and every four groups of cross beams 206 are connected by connecting ribs 209, and the cross beams 206 connected by the connecting ribs 209 can better provide support for the protective body 200.

[0028] Among them, preferably, the left locking block 2051 is a semicircular locking block structure, and the top and bottom ends of the left locking block 2051 are provided with movable grooves 2053, the inner cavity of the top movable groove 2053 is rotatably connected to the upper support shaft 2054, the outer wall of the upper support shaft 2054 is connected to the connecting screw 2055, and the inner cavity of the bottom movable groove 2053 is connected to the lower connecting block 2059 through the shaft.

[0029] Preferably, the outer end of the lower connecting block 2059 is connected to the bottom end of the right locking block 2052, and the top of the right locking block 2052 is set as a trapezoidal structure, and the trapezoidal structure is provided with a connecting groove 2056 corresponding to the position of the movable groove 2053, and the upper support shaft 2054 is connected to the connecting groove 2056, and the outer end of the upper support shaft 2054 is connected to the fixing bolt 2057, and the fixing bolt 2057 is connected to the inclined surface of the trapezoidal structure.

[0030] Please note that Figure 1 and Figure 2 When the cable structure 100 is placed into the protective body 200, the left locking block 2051 and the right locking block 2052 are merged through the lower connecting block 2059. At this time, the connecting screw 2055 just passes through the connecting slot 2056, and the upper support shaft 2054 connected to the connecting screw 2055 can change the direction of the connecting screw 2055, so that the connecting screw 2055 passes through the connecting slot 2056. When the fixing bolt 2057 is installed at the end of the connecting screw 2055 and tightened, the accommodating groove matching the fixing bolt 2057 opened on the trapezoidal structure plays a limiting role, including the stability of the protective body 200 after connection.

[0031] Preferably, two groups of clamping assemblies 2058 with the same structure are symmetrically arranged on the outer end surfaces of the left locking block 2051 and the right locking block 2052, and transverse grooves matching the clamping assemblies 2058 are opened on the left locking block 2051 and the right locking block 2052. The two groups of clamping assemblies 2058 are attached to the outer wall of the cable structure 100, which limits the cable structure 100 and prevents it from slipping out of the protective body 200 due to looseness.

[0032] Preferably, the clamping assembly 2058 includes a trapezoidal block 20581 connected in the transverse groove, the inner end of the trapezoidal block 20581 is connected to a supporting vertical shaft, and a torsion spring is connected to the supporting vertical shaft. The cooperation between the torsion spring and the supporting vertical shaft can ensure that the trapezoidal block 20581 always has an inward stress, thereby ensuring the clamping force of the two groups of clamping assemblies 2058 on the cable structure 100. A connecting shaft rod 20582 is installed on the outer end of the trapezoidal block 20581, and a limit block 20583 that does not contact the trapezoidal block 20581 is connected to the connecting shaft rod 20582, and the outer end of the limit block 20583 is connected to an arc-shaped clamping block 20584, the arc-shaped surfaces of the two groups of arc-shaped clamping blocks 20584 are opposite, and the arc-shaped clamping blocks 20584 are rubber clamping blocks.

[0033] Please note that Figure 2 and Figure 3 The cable structure 100 is prevented from being in the protective body 200. The two sets of trapezoidal blocks 20581 shrink inward by supporting the vertical axis and the torsion spring, so that the two sets of arc-shaped clamping blocks 20584 clamp the cable structure 100. The connecting shaft 20582 and the limit block 20583 ensure the clamping position of the arc-shaped clamping block 20584, and the arc-shaped clamping block 20584 made of rubber will not cause damage to the cable structure 100.
