Description

Technical Field

[0001] This application relates to the field of high mast lighting technology, and more particularly to high mast lighting power connection technology, specifically to a hook plug power connection device and a high mast light equipped with the device. Background Technology

[0002] High mast lighting generally refers to outdoor lighting devices that include a steel tapered pole of 15 meters or more and a retractable lamp panel. The lamp panel is equipped with multiple high-power lighting fixtures, so the power supply of the retractable lamp panel is very important.

[0003] Traditional high-mast lighting systems typically involve installing an electrical box and a lamp panel lifting system at the base of the pole. This electrical box contains a standard cable connector; one end of the cable connects to this connector, while the other end loops around a cable pulley mounted on a plate at the top of the pole to a junction box on the lamp panel. The other end of the junction box then supplies power to each lamp based on the required number of cables. This method is cumbersome, requiring manual unplugging and replugging of the cable connector at the base of the pole before each lamp panel raising or lowering. Furthermore, the cable rises and falls along with the steel cable that holds the lamp panel, increasing the risk of entanglement and damage. When the lamp panel descends to the bottom of the pole, tens of meters of cable are exposed, making them vulnerable to damage or even ruin in strong winds. This not only results in financial losses but also poses a significant safety hazard.

[0004] In some existing technologies, high mast lights connect to the ground by automatically attaching a female magnetic connector to a male magnetic connector. However, the magnetic connector attracts magnetic dust particles. Dust accumulation at the contact point of the magnetic connector increases contact resistance. The dust also weakens the magnetic force of the connector, reducing its attraction capacity and potentially leading to a less secure connection, thus affecting the stability and reliability of the high mast light's power connection. Utility Model Content

[0005] Therefore, this application provides a hook plug power connection device and a high mast light equipped with the device to solve the technical problems of low power connection stability of the electrical connector of the high mast light in the prior art, as well as the inconvenience and low safety of power connection of the high mast light.

[0006] To achieve the above objectives, this application provides the following technical solution:

The central axis of the hook post is provided with a through hole to accommodate the guide tube. The end of the hook post away from the post base is provided with a guide pin that matches the guide groove. When the guide pin is in the guide groove, the conductive plug is inserted into the conductive socket.

[0011] Optionally, both the first buffer assembly and the second buffer assembly include a guide rod and a spring sleeved on the outside of the guide rod. One end of the guide rod of the first buffer assembly is movably connected to the cylindrical base, and the other end of the guide rod of the first buffer assembly is fixedly connected to the conductive socket. The spring of the first buffer assembly abuts against the cylindrical base and the conductive socket. One end of the guide rod of the second buffer assembly is movably connected to the column base, and the other end of the guide rod of the second buffer assembly is fixedly connected to the conductive plug. The spring of the second buffer assembly abuts against the column base and the conductive plug.

[0012] Optionally, multiple conductive sockets are provided and evenly distributed around the hook cylinder, and the conductive plugs are correspondingly provided around the hook posts.

[0013] Optionally, the conductive socket is provided with a plurality of conductive holes, and the conductive plug is provided with conductive pins corresponding to the conductive holes.

[0014] Optionally, the fixing mechanism includes a cylindrical cover with openings at both ends, one end of the cylindrical cover being fixed to the cylindrical base, the hook fixing assembly and the conductive socket being placed inside the cylindrical cover, and the hook moving assembly and the conductive plug being movable within the cylindrical cover.

[0015] Optionally, the fixing mechanism and the moving mechanism are respectively provided with through holes that pass through the cylinder base, the guide tube, the column base and the hook cylinder in sequence, and the through holes are used to pass through the wire rope.

[0016] On the other hand, this application provides a high-mast light equipped with the above-mentioned hook plug power connection device, wherein the high-mast light is equipped with at least one of the hook plug power connection devices.

[0017] Optionally, the high-mast light includes a light pole, a light panel lifting system, and a light panel driving system. The light panel driving system is located at the top of the light pole, and the light panel lifting system is connected to the bottom of the light panel driving system. The light panel driving system includes a connecting plate fixedly mounted at the top of the light pole. Multiple driving arms are evenly arranged on the outer edge of the connecting plate. Each driving arm is provided with a pulley for guiding a steel wire rope. The end of the driving arm is fixedly connected to the upper side of the cylindrical base. A hook fixing assembly and a conductive socket are arranged adjacent to each other on the lower side of the cylindrical base. The conductive socket is connected to the main power cable inside the light pole. The light panel lifting system includes a light panel. A column base is arranged on the upper surface of the light panel corresponding to the fixing mechanism. A hook moving assembly and a conductive plug are arranged on the upper side of the column base. The conductive plug is connected to the main power cable of the lamp on the light panel.

[0018] A steel wire rope connects the lamp panel drive system and the lamp panel lifting system. One end of the steel wire rope is connected to the lamp panel lifting winch in the bottom cavity of the lamp post. The other end of the steel wire rope passes through the cylinder base, the guide tube, the column base, and the hook cylinder in sequence and is connected to the lamp panel. When the steel wire rope moves the lamp panel upward, the conductive plug and the conductive socket are connected to the electrode. The main power cable inside the lamp post is electrically connected to the main power cable of the lamp on the lamp panel. The moving mechanism is hooked to the bottom of the fixed mechanism through the hook moving assembly.

[0019] Compared with the prior art, this application has at least the following beneficial effects:

[0020] A hook-and-plug electrical connection device includes a fixing mechanism, a moving mechanism, and a plug guiding mechanism. The fixing mechanism has a hook fixing component and a conductive socket on its lower side of the cylindrical base. The moving mechanism has a hook moving component opposite to the hook fixing component and a conductive plug opposite to the conductive socket on its upper side of the column base. When the conductive plug and conductive socket are connected, the hook moving component hooks onto the hook fixing component, thus ensuring a stable connection between the conductive plug and the conductive socket. The conductive socket is connected to the cylindrical base via a first buffer component, and the conductive plug is connected to the column base via a second buffer component. These buffer components act as a buffer when the conductive socket and conductive plug mate, reducing the impact force and further improving the stability of the connection. The plug guiding mechanism incorporates a guide tube and guide pin. The guide pin on the hook column, guided by a corresponding guide groove on the guide tube, ensures precise alignment and reliable contact between the conductive plug and the conductive socket. Therefore, when this hook-and-plug electrical connection device is applied to high-mast lighting, it achieves high stability in the electrical connection of the high-mast lighting.

[0021] A high-mast light equipped with a hook plug power connection device has a fixing mechanism at the top of the light pole, which is connected to the main power cable inside the light pole. A moving mechanism is provided on the light panel. The light panel rises from the bottom of the light pole to the top, connecting the moving mechanism with the fixing mechanism to provide power. The main power cable at the bottom of the light pole no longer needs to move with the light panel, greatly improving the safety of power connection for the high-mast light. The moving mechanism and the fixing mechanism are connected by a hook-and-fixing assembly, which can be detached. When the fixing mechanism and the moving mechanism are hooked, the light panel is powered on; when the fixing mechanism and the moving mechanism are detached, the light panel is de-powered, making power connection for the high-mast light more convenient.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The purpose of this utility model is to provide a hook plug power connection device and a high mast light equipped with the device. The main purpose is to make the power connection of the high mast light's electrical connector more stable and to make the power connection of the high mast light more convenient and safer.

[0031] Example 1

[0032] Test Figure 1-3 As shown, Embodiment 1 provides a hook plug power connection device, including a fixing mechanism 1, a moving mechanism 2, and a plug guiding mechanism 3. The fixing mechanism 1 is used to fix to the top of the lamp post 4 of the high-mast light, and the moving mechanism 2 is located below the fixing mechanism 1. The moving mechanism 2 can be raised and lowered and is detachably connected to the fixing mechanism 1. The moving mechanism 2 is not powered when it is disconnected from the fixing mechanism 1.

[0033] Specifically, the fixing mechanism 1 includes a cylinder base 101, a hook fixing assembly 102 and a conductive socket 103 disposed adjacent to the lower side of the cylinder base 101. The hook fixing assembly 102 includes a hook cylinder 1021 with openings at both ends. One end of the hook cylinder 1021 is fixed to the cylinder base 101. The conductive socket 103 is connected to the cylinder base 101 through a first buffer assembly 104.

[0034] The moving mechanism 2 is located below the fixed mechanism 1. The moving mechanism 2 includes a column base 201, a hook moving component 202 connected to the upper side of the column base 201 and disposed opposite to the hook fixing component 102, and a conductive plug 203 disposed opposite to the conductive socket 103. The hook moving component 202 includes a hook post 2021 that can be inserted into the hook cylinder 1021. The hook post 2021 and the hook fixing component 102 can be hooked and detached. The conductive plug 203 is connected to the column base 201 through the second buffer component 204. When the conductive plug 203 is connected to the conductive socket 103 with the electrode plugged in, the hook post 2021 is hooked on the hook fixing component 102.

[0035] The hook fixing assembly 102 also includes two hook side plates with hook travel grooves and two anti-reverse shafts. The hook side plates are welded to the side of the hook cylinder 1021, and the two anti-reverse shafts are arranged between the two hook side plates. The two anti-reverse shafts are one-to-one with the two sets of hook travel grooves. A notch is provided on the cylinder wall of the hook cylinder 1021 between the hook travel grooves in the same set. When the anti-reverse shaft moves to the bottom of the hook travel groove through the notch, the shaft body of the anti-reverse shaft extends into the interior of the hook cylinder 1021. A travel spring is provided between the ends of the two anti-reverse shafts. The hook moving assembly 202 also includes a sleeve that can be slidably fitted outside the hook post 2021. The upper end of the hook post 2021 is provided with a slot for hooks to be hooked between the two anti-reverse shafts. During connection, when the hook post 2021 is inserted into the hook cylinder 1021, the top of the hook post 2021 first pushes the two anti-reverse shafts away from each other, allowing the hook post 2021 to pass between the two anti-reverse shafts. When the slot moves to the position of the anti-reverse shaft, the anti-reverse shaft is engaged in the slot under the action of the travel spring, thereby locking the hook post 2021 onto the hook fixing assembly 102. During disassembly, when the hook post 2021 continues to move upward until the two anti-reverse shafts are located outside the sleeve, and the two anti-reverse shafts clamp and fix the sleeve between the two anti-reverse shafts, at this time the sleeve covers the slot inside. Then the upward pulling force on the hook post 2021 is released, allowing the hook post 2021 to... 1. Falling under the influence of gravity, the sleeve is clamped and fixed between the two anti-reverse shafts. When the hook post 2021 falls, the position of the sleeve will not move until the sleeve abuts against the top of the hook post 2021. It should be noted that the top diameter of the hook post 2021 is larger than the middle and lower diameter. The sleeve is slidably set in the middle and lower part. The inner diameter of the sleeve is smaller than the top diameter of the hook post 2021. After the sleeve abuts against the top of the hook post 2021, the sleeve moves downward synchronously with the hook post 2021. As the sleeve and the top of the hook post 2021 move downward continuously, when passing between the two anti-reverse shafts, the hook post 2021 separates from the hook fixing assembly 102.

[0036] When the conductive plug 203 is inserted into the conductive socket 103 and the electrodes are connected, the hook moving component 202 hooks onto the hook fixing component 102, thereby making the conductive plug 203 and the conductive socket 103 stably connected. The conductive socket 103 is connected to the cylinder base 101 through the first buffer component 104, and the conductive plug 203 is connected to the column base 201 through the second buffer component 204. When the conductive socket 103 and the conductive plug 203 are connected, they play a buffering role, reducing the impact force generated during connection and further improving the stability of the connection.

[0037] The plug guiding mechanism 3 includes a guide tube 301 and a guide pin 302. One end of the guide tube 301 is fixed to the cylinder base 101, and the other end of the guide tube 301 is inserted into the hook cylinder 1021 and extends to the end of the hook cylinder 1021 away from the cylinder base 101. The guide tube 301 and the hook cylinder 1021 are coaxially arranged. One end of the guide tube 301 is provided with a guide groove extending axially from the guide tube 301 towards the cylinder base 101. The central axis of the hook post 2021 is provided with a through hole to accommodate the guide tube 301. The end of the hook post 2021 away from the post base 201 is provided with a guide pin 302 that matches the guide groove. When the guide pin 302 is in the guide groove, the conductive plug 203 is inserted into the conductive socket 103. The guide pin 302 is located above the slot, that is, after the guide pin 302 is inserted into the guide groove, the hook post 2021 is hooked onto the hook fixing assembly 102. The guide pin 302 is arranged radially along the hook post 2021. The guide pin 302 can only move upward in the guide groove so that the hook post 2021 can continue to approach the hook fixing assembly 102. The length of the guide groove must be sufficient to separate the hook post 2021 from the hook fixing assembly 102.

[0038] Thus, the guide tube 301 and guide pin 302 in the plug guide mechanism 3 are designed such that the guide pin 302 on the hook post 2021 is guided by the corresponding guide groove on the guide tube 301 to ensure the precise alignment and reliable contact between the conductive plug 203 and the conductive socket 103.

[0039] In this application, both the first buffer assembly 104 and the second buffer assembly 204 include a guide rod 1042 and a spring 1041 sleeved on the outside of the guide rod 1042. One end of the guide rod 1042 of the first buffer assembly 104 is movably connected to the cylinder seat 101, and the other end of the guide rod 1042 of the first buffer assembly 104 is fixedly connected to the conductive socket 103. The spring 1041 of the first buffer assembly 104 abuts against the cylinder seat 101 and the conductive socket 103. One end of the guide rod 1042 of the second buffer assembly 204 is movably connected to the column seat 201, and the other end of the guide rod 1042 of the second buffer assembly 204 is fixedly connected to the conductive plug 203. The spring 1041 of the second buffer assembly 204 abuts against the column seat 201 and the conductive plug 203. Therefore, firstly, when the conductive socket 103 and the conductive plug 203 are connected, the spring 1041 acts as a buffer to reduce the impact force generated during the connection; secondly, when the hook post 2021 needs to be separated from the hook moving assembly 202, the hook post 2021 needs to move further towards the cylinder base 101. During this process, the conductive socket 103 and the conductive plug 203 can still be stably connected, that is, the first buffer assembly 104 can provide clearance space for the conductive socket 103 and the conductive plug 203.

[0040] In this application, multiple conductive sockets 103 are provided and evenly distributed around the hook cylinder 1021. Conductive plugs 203 are correspondingly provided around the hook post 2021, with two conductive sockets 103 and two conductive plugs 203 being preferred. This allows the power supply to be distributed, making the connection more stable. The conductive plug 203 has multiple conductive pins, which can be three-pin, five-pin, or seven-pin. The conductive socket 103 has corresponding conductive holes for the conductive pins. Connecting the multi-pin conductive plug 203 to the multi-hole conductive socket 103 makes the power connection more stable and safer.

[0041] The fixing mechanism 1 also includes a cylindrical cover 105 with openings at both ends. One end of the cylindrical cover 105 is fixed to the cylindrical base 101. The hook fixing assembly 102 and the conductive socket 103 are placed inside the cylindrical cover 105. The hook moving assembly 202 and the conductive plug 203 can move inside the cylindrical cover 105. In this way, the cylindrical cover 105 can provide dust and rain protection.

[0042] In this application, the fixed mechanism 1 and the moving mechanism 2 are respectively provided with through holes that pass through the cylinder base 101, the guide tube 301, the column base 201 and the hook cylinder 1021 in sequence, and the through holes are used to thread the wire rope.

[0043] Example 2

[0044] refer to Figure 4As shown in Example 2, a high mast light equipped with a hook plug power connection device is provided. The high mast light has at least one hook plug power connection device installed. The following is a detailed explanation of how the hook plug power connection device is applied in a high mast light.

[0045] The high-mast light includes a light pole 4, a light panel lifting system, and a light panel drive system. The light panel drive system is installed at the top of the light pole 4, and the light panel lifting system is connected below the light panel drive system. The light panel lifting system can move up and down along the light pole 4 under the drive of the light panel drive system.

[0046] The lamp panel driving system includes a connecting plate 5 fixedly mounted on the top of the lamp post 4. Multiple driving arms 501 are evenly arranged on the outer edge of the connecting plate 5. Each driving arm 501 is provided with a pulley for guiding the wire rope. The end of the driving arm 501 is connected to the fixing mechanism 1 of the hook plug power connection device, that is, it is fixedly connected to the upper side of the cylinder base 101. The lower side of the cylinder base 101 is adjacent to the hook fixing component 102 and the conductive socket 103. The conductive socket 103 is connected to the main power cable inside the lamp post 4. The lamp panel lifting system includes a lamp panel 6. The upper surface of the lamp panel 6 is provided with a moving mechanism 2 corresponding to the fixing structure. That is, the upper surface of the lamp panel 6 is connected to the lower side of the column base 201. The upper side of the column base 201 is provided with the hook moving component 202 and the conductive plug 203. The conductive plug 203 is connected to the main power cable of the lamp on the lamp panel 6.

[0047] A steel wire rope connects the lamp panel drive system and the lamp panel lifting system. One end of the steel wire rope is connected to the lamp panel lifting winch in the bottom cavity of the lamp post 4. The other end of the steel wire rope passes through the drum base 101, guide tube 301, column base 201 and hook drum 1021 in sequence and is connected to the lamp panel 6. When the steel wire rope drives the lamp panel 6 to move upward, the conductive plug 203 and the conductive socket 103 are connected by electrodes. The main power cable in the lamp post 4 is electrically connected to the main power cable of the lamp on the lamp panel 6. The moving mechanism 2 is hooked to the bottom of the fixed mechanism 1 through the hook moving component 202. At this time, the lamp panel 6 is powered by the main power cable connected to the moving socket through the moving plug.

[0048] The light pole 4 is a hollow columnar structure. An operating door is installed on the side wall of the light pole 4 near the bottom. A control box is installed on the inner wall of the operating door, and operating buttons are installed on the control box. A light panel lifting winch connected to the control box is installed in the bottom cavity of the light pole 4.

[0049] Therefore, a fixing mechanism 1 is set at the top of the light pole 4, which is connected to the main power cable inside the light pole 4. A moving mechanism 2 is set on the light panel 6. The light panel 6 rises from the bottom to the top of the light pole 4 so that the moving mechanism 2 is connected to the fixing mechanism 1 and energized. The main power cable at the bottom of the light pole 4 no longer needs to move with the light panel 6, which greatly improves the safety of powering the high pole light. The moving mechanism 2 and the fixing mechanism 1 are connected by a hook-and-release connection through the hook post 2021 and the hook fixing component 102. When the fixing mechanism 1 and the moving mechanism 2 are hooked, the light panel 6 is energized. When the fixing mechanism 1 and the moving mechanism 2 are detached, the light panel 6 is de-energized, making it more convenient to power the high pole light.

[0050] In this embodiment, multiple drive arms 501 can be provided on the connecting plate 5, preferably three. The length direction of the drive arms 501 is arranged along the radial direction of the lamp post 4, and the drive arms 501 are evenly spaced along the circumference of the lamp post 4.

[0051] In this embodiment, at least one hook plug power connection device is installed between the drive arm 501 and the lamp panel 6, and the remaining drive arm 501 is connected to the corresponding position of the lamp panel 6 with a hook. The hook includes a hook moving component 202 and a hook fixing component 102, so as to ensure that the lamp panel 6 is safely fixed on the lamp pole 4, and also to ensure that the lamp panel 6 is stably powered.

[0052] The lamp panel 6 rises or falls via the lamp panel drive system. When the lamp panel 6 moves to the top of the lamp post 4 via the lamp panel drive system, the lamp panel 6 is connected to the conductive socket 103 of the moving mechanism 2 on the lamp panel 6 and the conductive socket 103 fixed at the top of the lamp post 4, so that the lamp on the lamp panel 6 is electrically connected to the power supply system. The lamp panel 6 is hooked to the top of the lamp post 4 via the hook moving assembly 202, so that the conductive plug 203 and the conductive socket 103 are stably connected.

[0053] In practical application, the lamp panel lifting system is located at the lower part of the lamp post 4 and is in a non-energized state. The lamp panel drive system is located at the upper part of the lamp post 4. The main power cable is connected to the lamp panel drive system through the inside of the lamp post 4, specifically to the conductive socket 103. One end of the wire rope is connected to the lamp panel lifting winch, and the other end extends inside the lamp post 4 to the drive arm 501 of the lamp panel drive system. Guided by the guide pulley, it passes through the cylinder base 101, guide tube 301, column base 201, and hook cylinder 1021 in sequence and connects to the lamp panel 6. The lamp panel 6 moves along the lamp post 4 towards the top of the lamp post 4 under the drive of the wire rope. When the conductive socket 103 and conductive plug 203 are connected and energized, or when the conductive socket 103 and conductive plug 203 are connected and energized, the lamp panel lifting system is in an energized state, and the lamp panel 6 is hooked to the top of the lamp post 4. When the lamp panel lifting system is detached from the lamp panel drive system, the conductive socket 103 and conductive plug 203 are separated, and the lamp panel lifting system is in a non-energized state. Throughout the process, the main power cable no longer moves with the lamp panel lifting system, making the use of high-mast lights safer.

[0054] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
