Description

Technical Field

[0001] This utility model relates to the field of street light technology, specifically a street light with a leakage current alarm structure. Background Technology

[0002] Streetlights are installed along roadsides to provide illumination for cities. During use, streetlights may leak electricity due to aging cables, loose connections, or poor contact. Since streetlight poles are generally made of metal, a leak can cause the pole to become electrified, potentially resulting in electric shock if a pedestrian touches it.

[0003] Currently, traditional streetlights rely heavily on passive protection modes such as circuit breaker tripping for leakage current protection. Tripping is only triggered when the leakage current reaches 30mA (the national standard threshold), failing to provide early warning. In outdoor scenarios, issues such as aging streetlight wiring, oxidation of connectors, and corrosion of the light pole can first cause "micro-leakage" (leakage current 5-10mA). At this time, the circuit breaker does not trip, but the current may be conducted to the ground through the light pole. If pedestrians touch the light pole or rainwater flows over the electrified light pole, it can easily cause electric shock accidents. Furthermore, the long-term existence of micro-leakage will accelerate the burning of the wiring, eventually leading to short circuit tripping, causing a large area of ​​streetlights to go out, affecting road lighting safety. In view of this, a streetlight with a leakage current alarm structure is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a street light with a leakage current alarm structure, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a street light with a leakage current alarm structure, comprising a base, a light pole fixedly connected to the upper side of the base, a light body fixedly installed on the top of the light pole, a support base fixedly connected to the outer wall of the light pole, an electrical control box provided on the support base, an alarm, an MCU control module and a circuit breaker fixedly installed in the electrical control box, and a protective component sleeved on the outer wall of the light pole; The protective components include a first protective sleeve, a first connecting block, a current sensor, an elastic sealing gasket, a second protective sleeve, a second connecting block, and bolts. The first and second protective sleeves can wrap around the lamp post after being fitted together. Both the first and second connecting blocks are threadedly connected to the bolts.

[0006] Preferably, the current sensor is fixedly installed inside the protective sleeve, and the detection part of the current sensor abuts against the lamp post.

[0007] Preferably, the interior of the elastic sealing gasket is hollow and filled with gas.

[0008] Preferably, the second protective sleeve has an inlay groove on the side near the first protective sleeve, and the inlay groove matches the elastic sealing gasket.

[0009] Preferably, an air chamber is embedded inside the connecting block one, a piston is connected to a piston component in the air chamber, the piston component and the air chamber are elastically connected by a return spring, a connecting rod is fixedly connected to the side of the piston component away from the return spring, and the air chamber and the elastic sealing gasket are connected by an air pipe.

[0010] Preferably, the connecting rod passes through the inner wall of the connecting block and is slidably connected to the inner wall of the connecting block, and the end of the connecting rod away from the piston is arc-shaped.

[0011] Preferably, the lamp post is a metal pole.

[0012] This utility model provides a street light with a leakage current alarm structure. It has the following beneficial effects: (1) This street light with a leakage current alarm structure solves the problem of traditional street lights only being able to passively trip by coordinating the current sensor of the protection component with the electrical control box. The current sensor is attached to the metal light pole and can detect the micro leakage current of the light pole in real time and transmit the data to the MCU control module. When a micro leakage current is detected, the MCU control module will immediately trigger the alarm without waiting for the leakage current to reach the tripping threshold, thus preventing the micro leakage current from persisting for a long time and accelerating the burnout of the circuit. Compared with traditional passive protection, this design can detect leakage hazards in advance, greatly reducing the risk of pedestrian electric shock and large-area street light outages.

[0013] (2) The street light with leakage alarm structure can provide double protection for the light pole through the use of protective components. Protective sleeve one and protective sleeve two are fixed by bolts and connecting blocks, which can wrap the outer wall of the light pole and prevent rainwater and dust from directly contacting the current sensor, thus achieving the effect of protecting the current sensor.

[0014] (3) The street light with leakage alarm structure uses the elastic sealing gasket, air chamber, connecting rod and air pipe in combination. When the bolt is inserted into the through hole of connecting block one to connect block two, the connecting rod is squeezed to move, so that the piston squeezes the return spring, and then the gas in the air chamber enters the elastic sealing gasket. The elastic sealing gasket expands and fits tightly with the inlay groove, improving the sealing effect when protective sleeve one and protective sleeve two are connected.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figures 1-5 This embodiment proposes a street light with a leakage current alarm structure, including a base 1, a light pole 2 fixedly connected to the upper side of the base 1, the light pole 2 being a metal pole body, a light body 3 fixedly installed on the top of the light pole 2, a support base 4 fixedly connected to the outer wall of the light pole 2, an electrical control box 5 provided on the support base 4, an alarm, an MCU control module and a circuit breaker fixedly installed in the electrical control box 5, and a protective component 6 sleeved on the outer wall of the light pole 2.

[0021] In this embodiment of the invention, the protective component 6 includes a first protective sleeve 61, a first connecting block 62, a current sensor 63, an elastic sealing gasket 64, a second protective sleeve 65, a second connecting block 66, and a bolt 67. The first protective sleeve 61 and the second protective sleeve 65 fit together to wrap the lamp post 2. Both the first connecting block 62 and the second connecting block 66 are threadedly connected to the bolt 67. The current sensor 63 is fixedly installed inside the first protective sleeve 61, and its detection part abuts against the lamp post 2. The second protective sleeve 65 has an opening on the side near the first protective sleeve 61. The inlay groove 651 matches the elastic sealing gasket 64. By assembling the first protective sleeve 61 and the second protective sleeve 65, the first connecting block 62 and the second connecting block 66 can be aligned, and then connected by bolts 67. The elastic sealing gasket 64 is inserted into the inlay groove 651 to achieve a sealing effect, preventing rainwater and dust from directly contacting the current sensor 63, thus protecting the current sensor 63. The current sensor 63 is attached to the metal light pole 2 and can detect the micro leakage current of the light pole 2 in real time and transmit the data to the MCU control module. When a micro leakage current is detected, the MCU control module will immediately trigger the alarm without waiting for the leakage current to reach the trip threshold, avoiding the long-term existence of micro leakage current and accelerating the burnout of the circuit. Compared with traditional passive protection, this design can detect leakage hazards in advance, greatly reducing the risk of electric shock to pedestrians and large-area street light failure.

[0022] In use, first connect the first protective sleeve 61 to the second protective sleeve 65, then connect the bolt 67 to the first connecting block 62 and the second connecting block 66 to complete the splicing of the first protective sleeve 61 and the second protective sleeve 65. The current sensor 63 is attached to the metal lamp post 2 and can detect the micro leakage current of the lamp post 2 in real time. When micro leakage is detected, there is no need to wait for the leakage current to reach the trip threshold. The MCU control module will immediately trigger the alarm to remind the staff to complete the leakage inspection of the street light.

[0023] Please see Figures 1-5Another embodiment of this utility model is as follows: the interior of the elastic sealing gasket 64 is hollow and filled with gas. An air chamber 621 is embedded inside the connecting block 62. A piston 622 is connected to the piston in the air chamber 621. The piston 622 and the air chamber 621 are elastically connected by a return spring. A connecting rod 623 is fixedly connected to the side of the piston 622 away from the return spring. The air chamber 621 and the elastic sealing gasket 64 are connected by an air pipe 624. 3. The connecting rod 623 penetrates the inner wall of the connecting block 62 and slides with the inner wall of the connecting block 62. The end of the connecting rod 623 away from the piston 622 is arc-shaped. During the process of the bolt 67 being inserted into the through hole of the connecting block 62, the connecting rod 623 is squeezed to move, causing the piston 622 to squeeze the return spring, thereby allowing the gas in the air chamber 621 to enter the elastic sealing gasket 64. The elastic sealing gasket 64 expands and fits tightly with the inlay groove 651, improving the sealing effect when the protective sleeve 61 and the protective sleeve 65 are connected.

[0024] In use, when connecting block 1 62 and connecting block 2 66 are aligned and connected by bolt 67, bolt 67 will squeeze connecting rod 623 to move, causing piston 622 to squeeze return spring, thereby allowing gas in air chamber 621 to enter elastic sealing gasket 64. Elastic sealing gasket 64 expands and fits tightly with inlay groove 651, reducing the gap between elastic sealing gasket 64 and inlay groove 651, thereby sealing and protecting current sensor 63.
