Description
Technical Field
[0001] This utility model belongs to the field of street light technology, and specifically relates to a rodent-proof sleeve device for the inside of a street light. Background Technology
[0002] Existing streetlight internal wiring has significant shortcomings in terms of rodent protection, mainly manifested in insufficient material protection, poor concealment, and maintenance difficulties. These shortcomings are closely related to design oversights and the usage environment. For example, the wiring is often made of ordinary PVC material, which is insufficient in hardness and bite resistance to resist long-term rodent gnawing. At the same time, the complex internal structure of streetlights makes it difficult to completely seal, providing rodents with hiding and activity spaces.
[0003] Conventional solutions mainly include regularly inspecting and replacing damaged pipelines, and using rodent-proof coatings or protective wraps. However, while these methods can alleviate the problem in the short term, they cannot fundamentally eliminate rodent infestation. Furthermore, frequent maintenance increases manpower and economic costs, and may also affect the normal operation of streetlights due to power outages, or even cause safety hazards. Therefore, we hope to design a novel rodent-proof sleeve device for the internal structure of streetlights to solve this problem. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rodent-proof sleeve device for the inside of a street light, thereby solving the problems mentioned in the background art.
[0005] This utility model is achieved through the following technical solution: a street light internal anti-rodent-biting sleeve device, comprising: a street light assembly, wherein a lower protective assembly for protecting the line sleeve is installed at the bottom of the street light assembly, and a sleeve protection assembly for protecting the sleeve is installed inside the upper side of the street light assembly, wherein the lower protective assembly comprises a metal tube formed by merging two half tubes, wherein a semi-circular plate is respectively provided on the front and rear sides of the middle of the metal tube, and a plurality of evenly distributed spikes are provided on the lower surface of the two semi-circular plates;
[0006] The sleeve protection assembly includes an outer protective half-pipe one and an outer protective half-pipe two. The outer protective half-pipe two is clamped on one side of the outer protective half-pipe. The outer wall of the outer protective half-pipe one and the outer protective half-pipe two as a whole is wrapped with a spiral winding tape.
[0007] In a preferred embodiment, the street light has an inner cavity, and a sleeve for installing wiring is installed inside the inner cavity. A semi-circular plate is provided on the front and rear sides of the upper end of the metal tube.
[0008] In a preferred embodiment, the lower end of the metal tube is welded with semicircular plates three by multiple connecting rods on the front and rear sides. The left and right sides of the two semicircular plates three are respectively connected downward to form a through hole for bolts to fix it to the lower end of the street light assembly. In actual use, the metal tube is divided into two parts, and two semicircular plates one, two semicircular plates two, and two semicircular plates three are respectively placed on the outer and rear sides of the metal tube. After the entire lower protective assembly is fixed to the bottom of the street light assembly by the two semicircular plates three, the entire device can form an enclosed structure, thereby wrapping the sleeve of the installed line and preventing rats from gnawing on the sleeve of the installed line from the bottom.
[0009] In a preferred embodiment, the plurality of evenly distributed spikes—the tips of which are all inclined toward the axis of the metal tube at an angle of 30 degrees.
[0010] In a preferred embodiment, the right front and rear sides of the outer protective half-pipe are respectively provided with interlocking saw teeth one, and the left front and rear sides of the outer protective half-pipe are respectively provided with interlocking saw teeth two. The outer protective half-pipe one and the outer protective half-pipe two are interlocked with each other through the interlocking saw teeth one and the interlocking saw teeth two to form a complete rodent-proof pipe.
[0011] In a preferred embodiment, the outer wall of the first outer protective half-pipe is provided with a plurality of recessed embedding grooves in the vertical direction, and the outer wall of the second outer protective half-pipe is provided with a plurality of recessed embedding grooves in the vertical direction. The plurality of embedding grooves 1 and 2 are interlocked to form a spiral embedding groove structure for installing a spiral winding tape. In actual use, the spiral winding tape can be made of metal tape, which can be aligned and fixed after winding the first and second outer protective half-pipes. The spiral winding tape can effectively prevent rats from gnawing on it through the spikes on it.
[0012] In a preferred embodiment, the cross-sectional width and thickness of the spiral winding strip are matched with the cross-sectional width and depth of the first and second embedding grooves, and the outer wall of the spiral winding strip is provided with spikes to prevent rodent bites.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are: by setting the lower protective component, the metal tube makes it difficult for rats to gnaw on the inner sleeve, while the spikes on the lower side of the semicircular plate can prevent rats from climbing upwards and prevent rats from entering the upper side of the inner cavity.
[0014] 2. By setting up a sleeve protection component, the spiral winding tape can constrain the overall structure of the outer protective half-pipe one and outer protective half-pipe two after winding. After winding, an external metal clamp can be used for secondary reinforcement. The lower end of the entire sleeve protection component can be fitted onto the upper side of the metal pipe when installing the lower protection component. The inner diameter of the overall structure of the outer protective half-pipe one and outer protective half-pipe two matches the outer diameter of the metal pipe. The semi-circular plate one on the metal pipe can support it. The synergistic effect of the lower protection component and the sleeve protection component effectively solves the problem that conventional periodic inspection and replacement of damaged pipelines, the use of rodent-proof coatings or protective wrapping are not enough to fundamentally eliminate rodent damage, ensuring that the sleeve of the installed line is difficult to be chewed by rats during subsequent use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] As the first embodiment of this utility model:
[0026] Please see Figures 1 to 5 A rodent-proof sleeve device for the interior of a street light includes: a street light assembly 100, a lower protective assembly 200 for protecting the sleeve is installed at the bottom of the street light assembly 100, and a sleeve protection assembly 300 for protecting the sleeve is installed inside the upper side of the street light assembly 100. The lower protective assembly 200 includes a metal tube 210 formed by merging two half tubes. A semi-circular plate 220 is respectively provided on the front and rear sides of the middle of the metal tube 210, and a plurality of evenly distributed spikes 221 are provided on the lower surface of the two semi-circular plates.
[0027] The sleeve protection assembly 300 includes an outer protective half-pipe one 310 and an outer protective half-pipe two 320. The outer protective half-pipe one 310 is fitted with the outer protective half-pipe two 320 on its side. The outer wall of the outer protective half-pipe one 310 and the outer protective half-pipe two 320 is wrapped with a spiral winding tape 330.
[0028] The street light has an inner cavity 110 inside, and a sleeve for installing wiring is installed inside the inner cavity 110. A semi-circular plate 211 is installed on the front and rear sides of the upper end of the metal tube 210.
[0029] The lower end of the metal tube 210 has a semi-circular plate 230 welded to its front and rear sides by multiple connecting rods. The two semi-circular plates 230 extend downwards to form a through hole on their left and right sides, respectively, for use with bolts to fix it to the lower end of the street light assembly 100. In actual use, the metal tube 210 is divided into two parts, and two semi-circular plates 211, 220 and 230 are provided on it, respectively placed on the outer and rear sides of the metal tube 210. After the entire lower protective assembly 200 is fixed to the bottom of the street light assembly 100 by the two semi-circular plates 230, the entire device can form an enclosed structure, thereby wrapping the conduit for the installed wiring and preventing rats from gnawing on the conduit for the installed wiring from the bottom.
[0030] Multiple evenly distributed spikes 221 have their tips tilted toward the axis of the metal tube 210 at an angle of 30 degrees.
[0031] Specifically, by setting up the lower protective component 200, in actual use, firstly, half of the lower protective component 200, namely half of the metal tube 210 and its three semicircular plates 211, 220, and 230, is fixed inside the lower end of the street light assembly 100. Specifically, the semicircular plate 230 is fixed to the lower end of the street light assembly 100 with bolts, while the semicircular plate 220 abuts against the inner wall of the inner cavity 110 of the street light assembly 100. Finally, the sleeve with the wiring installed is placed into the pre-installed half of the metal tube 210, and then the other half is... Half of the lower protective assembly 200 is slid upward from the bottom of the inner cavity 110 until the semicircular plate 230 on the half of the lower protective assembly 200 is aligned with the bolt hole pre-set at the lower end of the street light assembly 100 and fixed with bolts. At this time, the entire lower protective assembly 200 will protect the lower end of the sleeve and be fixedly connected to the lower end of the street light. The metal tube 210 makes it difficult for rats to gnaw on the inner sleeve, while the spike 221 on the lower side of the semicircular plate 220 can prevent rats from climbing upward and prevent rats from entering the upper side of the inner cavity 110.
[0032] As the first embodiment of this utility model:
[0033] Please see Figures 1 to 5 The outer protective half-pipe 310 has interlocking saw teeth 1 on the front and rear sides of the right end, and interlocking saw teeth 2 on the front and rear sides of the left end. The outer protective half-pipe 310 and the outer protective half-pipe 320 are interlocked by interlocking saw teeth 1 and interlocking saw teeth 2 to form a complete rodent-proof pipe.
[0034] The outer wall of the first protective half-pipe 310 has multiple recessed embedding grooves 311 in the vertical direction, and the outer wall of the second protective half-pipe 320 has multiple recessed embedding grooves 321 in the vertical direction. The first and second embedding grooves 311 and the second embedding grooves 321 are connected to each other to form a spiral embedding groove structure for installing the spiral winding tape 330. In actual use, the spiral winding tape 330 can be made of metal strip, which can be aligned and fixed after winding the first protective half-pipe 310 and the second protective half-pipe 320. The spiral winding tape 330 can effectively prevent rats from gnawing on it through the spikes 221 on it.
[0035] The cross-sectional width and thickness of the spiral wound tape 330 are matched with the cross-sectional width and depth of the first embedding groove 311 and the second embedding groove 321, and the outer wall of the spiral wound tape 330 is provided with spikes 331 for rodent protection.
[0036] Based on the first embodiment described above, further, by setting the sleeve protection component 300, in actual use, the sleeve protection component 300 needs to be installed before the lower protection component 200 is installed. Specifically, first, a tube with pre-installed wiring is placed in the outer protective half-tube 310. Since the right front and rear sides of the outer protective half-tube 310 are respectively provided with interlocking sawtooth 1, and the left front and rear sides of the outer protective half-tube 310 are respectively provided with interlocking sawtooth 2, and the outer protective half-tube 310 and the outer protective half-tube 320 are interlocked by the interlocking sawtooth 1, The two serrations interlock to form a complete rodent-proof tube. Then, the outer protective half tube 320 is interlocked with the outer protective half tube 310 through the interlocking serrations 1 and 2, fixing the sleeve with the installed wires inside. Then, the spiral winding tape 330 with spikes 331 is wound into the embedding grooves 311 and 321 of the overall structure of the outer protective half tube 310 and the outer protective half tube 320. After winding, the spiral winding tape 330 can constrain the overall structure of the outer protective half tube 310 and the outer protective half tube 320.
[0037] After the winding is completed, an external metal clamp can be used for secondary reinforcement. The lower end of the entire sleeve protection assembly 300 can be fitted onto the upper side of the metal pipe 210 when the lower protection assembly 200 is installed. The inner diameter of the outer protective half-pipe 1 310 and the outer protective half-pipe 2 320 is matched with the outer diameter of the metal pipe 210. The semi-circular plate 1 211 on the metal pipe 210 can support it. The synergistic effect of the lower protection assembly 200 and the sleeve protection assembly 300 effectively solves the problem that conventional periodic inspection and replacement of damaged pipelines, the use of rodent-proof coatings or protective wrapping are not enough to fundamentally eliminate rodent damage, ensuring that the sleeve of the installed line is difficult to be chewed by rats during subsequent use.
