Description

Technical Field

[0001] This utility model relates to the technical field of cable fixing devices, specifically an EMC electromagnetic interference separator. Background Technology

[0002] With the continuous advancement of technology, the number of electrical devices on ships is increasing, and the system structure is becoming increasingly complex. For ships with electromagnetic compatibility (EMC) requirements, the spacing requirements for different types of cables and the electromagnetic interference between them present significant challenges, both at the design level and during on-site construction. Especially given the limited space inside a ship, ensuring that the spacing requirements for different types of cables are met becomes a critical issue.

[0003] Document CN 208738765 discloses a cable partition fixing device for preventing interference between cables of different properties. The device includes a cable tray, several partitions, several first fixing plates, and a number of partition supports equal to the number of first fixing plates. The first fixing plates are fixed at equal intervals between the two sides of the cable tray, and each first fixing plate has several first fixing holes for fixing the position of the cable on the first fixing plate. Each end of the partition support has a first waist-shaped groove, and both sides of the first fixing plates have mounting holes that match the first waist-shaped grooves. The upper surface of the partition support has several second waist-shaped grooves at equal intervals. One end of each partition has a vertical extension, and the extension has several third waist-shaped grooves at equal intervals along the fixed cable entry / exit direction that match the second waist-shaped grooves. This device has a relatively complex structure and high manufacturing cost. Furthermore, the partitions are L-shaped, which can cause vibrations in ships due to swaying, potentially leading to the screws fixing the partitions falling off and affecting stability.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses an EMC electromagnetic interference baffle. The baffle is simple to manufacture, has high strength, is easy to install, and effectively reduces electromagnetic interference between different types of cables, ensuring the normal operation of the ship's electrical system.

[0006] The technical solution of this utility model is: an EMC electromagnetic interference partition, including a partition located on a cable tray, with power cables and signal cables placed on both sides of the partition respectively. The partition is in the shape of an inverted U-shape, including a bottom horizontal plate, a vertical plate and a top horizontal plate. The cable tray is provided with several fixing holes, and support legs are provided around the cable tray.

[0007] By adopting the above technical solution, when power cables and signal cables are placed on cable trays, electromagnetic interference between different types of cables is avoided, ensuring the normal operation of the ship's electrical system. Since the overall operating environment of the device is on a ship at sea, the shape of the bulkhead can effectively prevent swaying and increase overall stability.

[0008] Preferably, the partition is integrally formed, with the bottom horizontal plate and the top horizontal plate being parallel to each other, and the vertical plate being perpendicular to the position between the top horizontal plate and the bottom horizontal plate.

[0009] By adopting the above technical solution, when the device is installed on a ship and transported at sea, it will generate swaying vibration. The top horizontal plate at the top of the vertical plate can offset part of this vibration due to gravity, thereby reducing the frequency of swaying and improving the overall stability of the bulkhead.

[0010] Preferably, the top horizontal plate and the bottom horizontal plate are located on one side of the vertical plate, and the bottom horizontal plate is provided with bolt holes that are compatible with the fixing holes of the cable tray. The bottom horizontal plate is fixed to the tray plate by bolts.

[0011] By adopting the above technical solution, the bolt holes on the bottom horizontal plate can be locked in the appropriate positions according to the number of power cables and signal cables on both sides of the partition, which is highly adaptable.

[0012] Preferably, the cable tray includes a tray plate arranged horizontally, with the tray plates arranged in parallel, and fixing holes evenly penetrating the tray plates in sequence. The two ends of the tray plate are fixed to the side plate by bolts.

[0013] By adopting the above technical solution, the bracket plate is used to support the cable and is placed on the ship by the support legs.

[0014] Preferably, the height of the support leg is greater than the height of the side plate, the support leg is L-shaped outward, and the L-shaped side plate of the support leg is fixed to the outside of the side plate by bolts.

[0015] By adopting the above technical solution, the support legs support the entire cable tray, and the support legs are higher than the cable tray to facilitate the placement of the cable tray on the upper layer.

[0016] Preferably, the length of the partition is at least greater than the distance between adjacent bracket plates, and the length of the bracket plate is greater than the width of the power cable assembly, the width of the signal cable assembly, and the overall width between the bottom cross plates.

[0017] By adopting the above technical solution, when a pile of power cables, signal cables, or other types of cables are placed on the bracket plate, there is a corresponding position for the partition to be placed, and it is fixed by bolt holes on the bottom horizontal plate of the partition.

[0018] Preferably, the power cable and signal cable are bundled together with cable ties and placed on both sides of the bracket plate, with a spacing between the power cable and signal cable for placing the partition.

[0019] By adopting the above technical solution, power cables and signal cables are fixed to the bracket plate with cable ties to prevent them from scattering or shifting during ship transportation.

[0020] The advantages of this utility model are as follows: 1. By setting up an inverted U-shaped partition between different types of cables, this utility model can offset some of the shaking when the ship vibrates and sways during ocean navigation, even if the ship is turbulent and shakes. This reduces the overall vibration frequency and improves the overall stability and firmness.

[0021] 2. This utility model uses cable ties to bind the cable to the bracket plate, which is simple, convenient, quick, and highly stable, effectively improving work efficiency.

[0022] 3. The partition of this utility model is simple to manufacture, has high strength, is easy to install, and effectively reduces electromagnetic interference between different types of cables, ensuring the normal operation of the ship's electrical system. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1-4As shown, the EMC electromagnetic interference baffle includes a baffle 1 located on a cable tray. Power cables 4 and signal cables 5 are placed on both sides of the baffle 1. The baffle 1 is generally U-shaped, including a bottom horizontal plate 101, a vertical plate 102 and a top horizontal plate 103. The cable tray is provided with several fixing holes 301 and support legs 6 are provided around the cable tray. When the power cables 4 and signal cables 5 are placed on the cable tray, electromagnetic interference between different types of cables is avoided, ensuring the normal operation of the ship's electrical system. Since the overall use environment of the device is on a ship at sea, the shape of the baffle 1 can effectively prevent swaying and increase the overall stability.

[0030] The partition 1 is integrally formed. The bottom horizontal plate 101 and the top horizontal plate 103 are parallel to each other, and the vertical plate 102 is perpendicular to the position between the top horizontal plate 103 and the bottom horizontal plate 101. When the device is installed on a ship and transported at sea, it will generate swaying vibration. The top horizontal plate 103 above the vertical plate 102 can offset part of this swaying vibration due to gravity, thereby reducing the frequency of swaying and improving the overall stability of the partition 1.

[0031] The top horizontal plate 101 and the bottom horizontal plate 103 are located on one side of the vertical plate 102. The bottom horizontal plate 101 is provided with bolt holes 1031 that are compatible with the fixing holes 301 of the cable bracket. The bolt holes 1031 are used to fix the bottom horizontal plate 103 to the bracket plate 3 by bolts 2. The bolt holes 1031 on the bottom horizontal plate 101 can be locked in the corresponding positions according to the number of power cables 4 and signal cables 5 on both sides of the partition 1, which is highly adaptable.

[0032] The cable tray includes a horizontally arranged tray plate 3, which is arranged in parallel with each other. Fixing holes 301 are evenly inserted through the tray plate 3 in sequence. The two ends of the tray plate 3 are fixed to the side plate 7 by bolts. The tray plate 3 is used to support cables and is placed on the ship by support legs 6.

[0033] The height of the support leg 6 is greater than the height of the side plate 7. The support leg 6 is L-shaped and extends outward. The L-shaped side plate 7 of the support leg 6 is fixed to the outside of the side plate 7 with bolts. The support leg 6 supports the entire cable tray. The support leg 6 is higher than the cable tray, which makes it convenient for the upper layer of cable tray to be placed.

[0034] The length of the partition 1 is at least greater than the distance between adjacent bracket plates 3. The length of the bracket plate 3 is greater than the width of the power cable 4 bundle, the width of the signal cable 5 bundle, and the overall width between the bottom horizontal plates 101. When the power cables 4 and signal cables 5 or other types of cables are stacked on the bracket plate 3, there is a corresponding position for the partition 1 to be placed and fixed through the bolt holes 1031 on the bottom horizontal plate 103 of the partition 1.

[0035] The power cable 4 and the signal cable 5 are tied together with cable ties 8 and placed on both sides of the length of the bracket plate 3. There is a gap between the power cable 4 and the signal cable 5 for the partition plate 1 to be placed. The power cable 4 and the signal cable 5 are fixed on the bracket plate 3 by the cable ties 8 to prevent them from falling or shifting during ship transportation.

[0036] Place the cable tray in the appropriate position on the ship, then place the power cable 4 and signal cable 5, or other cables of the same type, together, and place cables of different types on both sides of the tray plate 3. Bundle the cables with cable ties and secure them by passing them through the fixing holes 301 in the tray plate 3 to prevent the cables from shifting or falling. There is a gap between the cables for the placement of the partition plate 1. The bolt holes 1031 on the bottom horizontal plate 103 of the partition plate 1 are fixed to the tray plate 3 by bolts, which can effectively prevent electromagnetic interference between different cables. Alternatively, any different types of cable stacks can be placed on the tray plate 3, and electromagnetic interference can be prevented as long as the partition plate 1 is set between the cable stacks.

[0037] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
