Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a protective device for building lighting cable pipelines. Background Technology

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated conductors, and their respective possible coverings, overall protective layers, and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] Cables are widely used in the power industry. In the field of building lighting, cables are buried directly underground. Because there are no protective mechanisms, the cables may be damaged by small animals underground, causing power outages. In addition, during some construction projects, without protective mechanisms, the cables may be dug up due to operational errors, resulting in significant losses. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for building lighting cable pipelines to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective device for building lighting cable conduits includes an upper protective frame and a lower protective frame. The inner side of the lower protective frame has multiple convex placement slots, and each of the multiple convex placement slots contains a convex placement plate. A Y-shaped support frame is fixedly installed on the top of each convex placement plate. Pressure plates are provided on both sides of the top of each convex placement plate. An L-shaped connecting plate is fixedly installed on the top of each pressure plate. The end of the L-shaped connecting plate away from the pressure plate is fixedly installed on the inner side of the upper protective frame. The upper and lower protective frames are fixedly connected by a fastening mechanism.

[0007] Furthermore, a slot is provided on one bottom side of the lower protective frame, and a limiting block is fixedly installed at the bottom of the slot. A block is fixedly installed on the other side of the lower protective frame, and a limiting groove is provided on the top of the block.

[0008] Furthermore, the card block is engaged in the card slot, and the limiting block is engaged in the limiting slot.

[0009] Furthermore, the fastening mechanism includes an alignment plate fixedly installed at the bottom of an L-shaped connecting plate near the side of the card block. The alignment plate has a non-through threaded groove. A fixing plate is fixedly installed on the inner side of the lower protective frame. The fixing plate has a through threaded hole. Fastening bolts are screwed into the threaded groove and the threaded hole.

[0010] Furthermore, the card block is integrally connected to the lower protective frame.

[0011] Furthermore, the number of convex placement slots is three, and the spacing between any two adjacent convex placement slots is the same.

[0012] Furthermore, both the upper and lower protective frames are U-shaped.

[0013] Furthermore, a positioning block is fixedly installed at the bottom of the upper protective frame, and a positioning groove is fixedly installed at the top of the lower protective frame, with the positioning block being engaged in the positioning groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model allows the buried cable to be erected on a Y-shaped support frame arranged in sequence. Since the Y-shaped support frame is located inside the upper and lower protective frames, the cable is protected by the upper and lower protective frames, which can prevent the cable from being damaged by small animals underground and causing power outages.

[0016] 2. This utility model allows the buried cable to be erected on a Y-shaped support frame arranged in sequence. Since the Y-shaped support frame is located inside the upper and lower protective frames, the cable is protected by the upper and lower protective frames, which can prevent the cable from being accidentally dug up during construction.

[0017] 3. This utility model allows the buried cable to be erected on a Y-shaped support frame arranged in sequence. Since the Y-shaped support frame is located inside the upper and lower protective frames, a heat dissipation channel is formed between the upper and lower protective frames, which can better dissipate heat from the cable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-12A protective device for building lighting cable conduits includes an upper protective frame 1 and a lower protective frame 2. The inner side of the lower protective frame 2 is provided with three convex placement grooves 3, and the spacing between any two adjacent convex placement grooves 3 is the same. A convex placement plate 4 is placed in each of the three convex placement grooves 3. A Y-shaped support frame 5 is fixedly installed on the top of the convex placement plate 4. Pressure plates 6 are provided on both sides of the top of the convex placement plate 5. An L-shaped connecting plate 7 is fixedly installed on the top of the pressure plate 6. The end of the L-shaped connecting plate 7 away from the pressure plate 6 is fixedly installed on the inner side of the upper protective frame 1. The upper protective frame 1 and the lower protective frame 2 are fixedly connected by a fastening mechanism 8.

[0033] In the above embodiments,

[0034] Specifically, a slot 9 is provided on one side of the bottom of the lower protective frame 2, and a limiting block 10 is fixedly installed at the bottom of the slot 9. A block 11 is fixedly installed on the other side of the lower protective frame 2, and a limiting groove 12 is provided on the top of the block 11. The block 11 is engaged in the slot 9, and the limiting block 10 is engaged in the limiting groove 12.

[0035] In the above embodiment, by engaging the locking block 11 in the locking slot 9 and the limiting block 10 in the limiting slot 12, the two adjacent lower protective frames are assembled and installed.

[0036] Specifically, the fastening mechanism 8 includes an alignment plate 8a fixedly installed at the bottom of an L-shaped connecting plate 7 near the side of the card block 11. The alignment plate 8a has a non-penetrating threaded groove 8b. A fixing plate 8c is fixedly installed on the inner side of the lower protective frame 2. The fixing plate 8c has a through threaded hole 8d. Fastening bolts 8e are screwed into the threaded groove 8b and the threaded hole 8d.

[0037] In the above embodiment, the alignment plate 8a and the fixing plate 8c are fastened together by screwing the fastening bolt 8e into the threaded groove 8b and the threaded hole 8d.

[0038] Specifically, the card block 11 is integrally connected to the lower protective frame 2.

[0039] In the above embodiment, by making the card block 11 and the lower protective frame 2 integrally connected, the connection between the card block 11 and the lower protective frame 2 is more secure.

[0040] Specifically, both the upper protective frame 1 and the lower protective frame 2 are U-shaped.

[0041] In the above embodiments, since both the upper protective frame 1 and the lower protective frame 2 are U-shaped, it is convenient to assemble the upper protective frame 1 and the lower protective frame 2 together.

[0042] Specifically, a positioning block 13 is fixedly installed at the bottom of the upper protective frame 1, and a positioning groove 14 is fixedly installed at the top of the lower protective frame 2, with the positioning block 13 locked in the positioning groove 14.

[0044] Working principle: During installation, the first lower protective frame 2 is placed into the pre-dug trench. Then, the slot 9 at the bottom of the other lower protective frame 2 is inserted into the block 11 on one side of the first lower protective frame 2. At the same time, the limiting block 10 at the bottom of the slot 9 is inserted into the limiting groove 12 at the top of the block 11, thus completing the assembly between two adjacent lower protective frames 2. Subsequently, multiple lower protective frames 2 are installed and assembled in sequence using this method. After all the lower protective frames 2 are installed, the convex placement plate 4 is then inserted into the trench. The cable to be buried (not shown in the figure) is placed in the convex placement groove 3 and then laid on the Y-shaped support frame 5 arranged in sequence. Then the upper protective frame 1 is installed in sequence by inserting the positioning block 13 at the bottom of the upper protective frame 1 into the positioning groove 14 at the top of the lower protective frame 2. Then the fastening bolt 8e is screwed into the threaded groove 8b and the threaded hole 8d to lock the upper protective frame 1 and the lower protective frame 2 together. Then, in this way, multiple upper protective frames 1 are fixed above the corresponding lower protective frames 2 to complete the installation of the entire protective device.
