Description

Technical Field

[0001] The utility model relates to the technical field of port equipment power supply, and particularly relates to a high-voltage cable high-voltage pit passing device for port equipment. Background Art

[0002] In a port, high-voltage electrical equipment such as substations, distribution rooms, charging piles, etc. are important energy bases to ensure the normal operation of port communication, security, informatization and other facilities. The stable operation of these devices plays an important role in the safe production and economic benefits of the port.

[0003] In the port operation area, especially when involving large-scale loading and unloading equipment such as cranes, conveyor belts or other power-driven equipment, there is usually a high-voltage power system to support the operation of these equipment. These systems may include high-voltage cables, switch cabinets, transformers, distribution panels, etc., and these components are responsible for delivering power from the main power grid to each electrical equipment.

[0004] In some cases, due to the layout of the equipment, safety regulations or power requirements, high-voltage power facilities may be placed in specific "high-voltage pits". Such a layout can reduce the risk of personnel accidentally contacting high-voltage equipment and make the maintenance and management of the equipment more convenient.

[0005] During the application of these port large-scale equipment, high-voltage cables are required to supply power to the equipment. One end of the high-voltage cable is connected to the high-voltage pit on the ground, and the other end is connected to the port equipment. In actual operation, generally, multiple devices will be placed on the same operation line in the port for operation, which results in the equipment on both sides necessarily passing through the high-voltage pit of the middle equipment. For safety reasons, the high-voltage pit must be covered with an end cover, which makes it difficult for the cables of the equipment on both sides to pass through the high-voltage pit of the middle equipment normally. Content of the Utility Model

[0006] Aiming at the technical problems such as potential safety hazards caused by high-voltage cables passing through high-voltage pits when multiple port devices are working, the purpose of the utility model is to provide a high-voltage cable high-voltage pit passing device for port equipment, which is suitable for multiple high-voltage cables to pass through the high-voltage pit of the middle equipment and improves the safety of power supply.

[0007] The utility model provides a high-voltage cable high-voltage pit passing device for port equipment, which includes a first steel plate and a second steel plate. There is a U-shaped groove between the first steel plate and the second steel plate. The upper edges on both sides of the U-shaped groove are perpendicularly welded to the first steel plate and the second steel plate respectively. At least one partition is arranged in the U-shaped groove, and the lower end surface of the partition is perpendicularly welded to the bottom plate of the U-shaped groove. All partitions divide the inside of the U-shaped groove into several positioning grooves. At least one positioning part is arranged in each positioning groove. The positioning part includes a positioning block whose outer shell shape matches the inner wall of the positioning groove. An inverted conical groove is opened on the upper end surface of the positioning block. Both ends of the inverted conical groove are open and an anti-slip layer is bonded on the inner wall; there is also a sealing rubber sheet in the U-shaped groove. The lower surface of the sealing rubber sheet is bonded to the first steel plate, the partition and the second steel plate respectively. A strip-shaped sealing seam is opened on the sealing rubber sheet directly above each positioning groove.

[0008] Further, the anti-slip layer is a rubber layer, a silica gel layer or a frosted layer.

[0009] Further, a plurality of parallel support bars are welded on the lower surfaces of the first steel plate and the second steel plate. The ends of all the support bars are perpendicularly fixed to the outer side surface of the U-shaped groove. The function is to support the steel plate and reinforce the steel plate at the same time.

[0010] Further, a rubber buffer layer is bonded to the lower end surface of the support bar to achieve a buffering effect during support.

[0011] Further, two cushion blocks are welded to the lower end surface of the positioning part, and a water flow channel is formed between the two cushion blocks.

[0012] Further, the bottom plate of the U-shaped groove is inclined.

[0013] The beneficial effects of the utility model are as follows;

[0014] The utility model can enable the high-voltage cable to safely pass through the high-voltage pit of the intermediate equipment, and solves the technical problem of potential safety hazards brought when multiple high-voltage cables pass through the high-voltage pit. The utility model is provided with a sealing rubber sheet for closing the opening of the U-shaped groove. The cable can enter the U-shaped groove through the strip-shaped sealing seam. After the high-voltage cable enters, the sealing rubber deformation sheet restores to seal the inside of the groove. The operation is convenient, isolating the high-voltage cable from the outside and improving the safety. The utility model adopts a positioning block with an inverted conical groove structure, which can fix cables with different diameters when the high-voltage cable is put in.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] As Figures 1-4 , the present utility model provides a high-voltage cable high-pressure pit passing device for port equipment, including a first steel plate 1 and a second steel plate 7. There is a U-shaped groove 10 between the first steel plate 1 and the second steel plate 7. The upper edges on both sides of the U-shaped groove 10 are perpendicularly welded to the first steel plate 1 and the second steel plate 7 respectively. There are two partition boards 9 in the U-shaped groove 10. The lower end surfaces of the partition boards 9 are perpendicularly welded to the bottom plate of the U-shaped groove 10. All the partition boards 9 divide the inside of the U-shaped groove 10 into several positioning grooves 3, and there are two positioning members 8 in each positioning groove 3.

[0027] As shown in Figure 2 , a structural schematic diagram of the positioning member 8 is shown. The positioning member 8 includes a positioning block 81 whose outer shell shape matches the inner wall of the positioning groove 3. An inverted conical groove 82 is formed on the upper end surface of the positioning block 81. The inverted conical groove 82 has openings at both ends and an anti-slip layer 83 is bonded to the inner wall. The anti-slip layer 83 is a rubber layer. There is also a sealing rubber sheet 6 in the U-shaped groove 10. The lower surface of the sealing rubber sheet 6 is bonded to the first steel plate 1, the partition plate 9, and the second steel plate 7 respectively. Specifically, the sealing rubber sheet 6 is bonded to the first steel plate 1 through the first bonding point 2, the sealing rubber sheet 6 is bonded to the upper end surfaces of the two partition plates 9 through two second bonding points 5, and the sealing rubber sheet 6 is bonded to the second steel plate 7 through the third bonding point 12. A strip-shaped sealing slit 4 is formed on the sealing rubber sheet 6 directly above each positioning groove 3.

[0028] In the present utility model, a plurality of parallel support bars 11 are welded to the lower surfaces of the first steel plate 1 and the second steel plate 7. The ends of all the support bars 11 are perpendicularly fixed to the outer side surface of the U-shaped groove 10. The function is to support the steel plates and reinforce the steel plates at the same time. A rubber buffer layer is bonded to the lower end surface of the support bar 11 to achieve a buffering effect during support.

[0029] As shown in Figure 7 , when the present utility model is used, the first steel plate 1 and the second steel plate 7 are supported on the edge of the opening of the high-pressure pit to form a closure for the opening of the high-pressure pit. The high-voltage cable 13 of the passing equipment then passes through the strip-shaped sealing slit 4 downward and enters the inverted conical groove 82. The width of the inverted conical groove 82 gradually decreases from top to bottom, which is suitable for the fixed positioning of multiple high-voltage cables 13 with different diameters. At the same time, an anti-slip layer 83 is bonded to the inner wall of the inverted conical groove 82. The anti-slip layer 83 is in contact with the rubber high-voltage cable 13. Under the action of friction, the high-voltage cable 13 can be prevented from moving, improving the fixed positioning effect.

[0030] Embodiment 2

[0031] The difference between Embodiment 2 and Embodiment 1 is that, as shown in Figure 5 , two cushion blocks 84 are welded to the lower end surface of the positioning member 8, and a water flow channel 85 is formed between the two cushion blocks 84. At the same time, as shown in Figure 6 , the bottom plate of the U-shaped groove 10 is inclined. The function is that when water enters the positioning groove 3, under the action of gravity, the accumulated water will flow along the inclined bottom plate and then be discharged at the end opening, preventing water from accumulating in the groove.

[0032] Although the present utility model has been described in detail by referring to the accompanying drawings and in conjunction with the preferred embodiments, the present utility model is not limited thereto. Without departing from the spirit and essence of the present utility model, those of ordinary skill in the art can make various equivalent modifications or substitutions to the embodiments of the present utility model, and these modifications or substitutions should all be within the scope covered by the present utility model / Any person skilled in the art within the technical scope disclosed by the present utility model can easily conceive of changes or substitutions, and all should be covered within the protection scope of the present utility model.
