Description

Technical Field

[0001] This utility model relates to a traffic signal controller, specifically a traffic signal controller with high protection capabilities. Background Technology

[0002] Traffic lights, also known as traffic signal lights, are equipped with traffic signal controllers located near traffic light intersections. These controllers are devices that can change the sequence of road traffic signals, adjust timing, and control the operation of road traffic lights. Since they are typically installed not far from either side of the road, their protection is crucial during installation, necessitating the protection of the internal components of the traffic signal controller.

[0003] The internal component protection of traffic signal controllers is divided into physical protection, circuit protection, and heat dissipation protection. Physical protection strengthens the outer casing, circuit protection prevents excessive current from damaging internal components, and heat dissipation protection cools the internal components to ensure stable operation.

[0004] In the existing technology, the housing of traffic signal controllers is relatively thin, using sheet metal shells with paint, and the housing is relatively thin, making it weak in impact resistance.

[0005] In the existing technology, the heat dissipation protection of traffic signal controllers is achieved by installing multiple fans on the cabinet, but this heat dissipation effect is insufficient and dust easily accumulates inside the cabinet.

[0006] In view of this, it is necessary to improve the traditional traffic signal controller. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a traffic signal controller with high protection function.

The thinnest part of the cabinet 1 is 4mm thick.

[0040] The cabinet 1 has a cold-rolled steel shell and a cabinet door 12 on its front. The outer side of the cabinet door 12 has a first protrusion 2 and a second protrusion 11 distributed vertically. The top of the cabinet 1 is designed as a concave structure and a guide channel 4 is provided in the concave structure. The guide channel 4 is used to guide rainwater to the corner of the top of the cabinet 1 so that the rainwater flows down from the side.

[0041] The second boss 11 is provided with a rocker switch 5, which is used to open the second boss 11.

[0042] The front of the cabinet 1 is equipped with a display screen 3, which is covered with explosion-proof glass. The explosion-proof glass is 3C explosion-proof glass, which has high hardness and strong impact resistance. The display screen 3 displays the working status of the traffic lights and shows it on the screen in the form of illustrations.

[0043] The back of the cabinet 1 forms a concave surface, and multiple equidistant vertical rods 6 are connected between the upper and lower sides of the concave surface. These vertical rods 6 are hollow and communicate with the upper and lower internal spaces of the cabinet 1. The vertical rods 6 are part of the heat dissipation system. The heat dissipation system also includes a first protrusion 2 and a concrete block 9 on the ground. The concrete block 9 has a hollow internal structure, with an opening on its top surface and a waterproof protrusion 10 fixed therein. The cavity of the concrete block 9 has a cable passage and an air passage. The bottom surface of the cabinet 1 has an opening large enough to accommodate the waterproof protrusion 10. An exhaust fan is mounted at the opening on the bottom surface of the cabinet 1, with the airflow directed towards the waterproof protrusion 10. A cable tray is included in the structure housing the exhaust fan to allow cables to pass through.

[0044] The waterproof protrusion 10 is used for cable and air passage. An exhaust vent is provided on one side of the cement block 9, and the exhaust vent is equipped with a rainproof structure.

[0045] The interior of the cabinet 1 is divided into two layers by a partition. The upper layer is the upper internal space, and the lower layer is the lower internal space. The cable routing holes on the partition are sealed after the cables pass through. The upper internal space houses the electrical components that control the traffic lights, while the lower internal space houses the power supply modules such as transformers and terminal blocks.

[0046] The first boss 2 is an iron shell, which includes a rectangular boss body 21; the interior of the boss body 21 is a groove that communicates with the internal space, and its bottom surface is provided with an air inlet mesh 22 that communicates with the groove.

[0047] A dehumidifying filter plate 24 is fixed at the opening of the trough surface. The dehumidifying filter plate 24 is a carbon filter plate, and the carbon filter plate is configured with a honeycomb air passage structure.

[0048] The bottom surface of the boss body 21 is magnetically attached to a dust filter plate 23, which is magnetic and has dense mesh holes. Example 2:

[0049] The inner and outer surfaces of the cold-rolled steel shell are coated with a phosphorus-free electrostatic powder coating, which has an antistatic effect. Example 3:

[0050] The following is the installation structure of the traffic signal controller of this utility model:

[0051] The bottom of the cabinet 1 is equipped with connecting posts 7 at the four corners, and each connecting post 7 has a groove around its circumference. The traffic signal controller is also equipped with anchors 8, which include an anchor 81 with a ring at one end and a set screw 83. The anchor 81 has a first through hole, and a side rod 82 is welded to its side wall. The side rod 82 has a second through hole communicating with the first through hole. The second through hole is provided with internal threads, and the set screw 83 engages with the internal threads and can extend into the first through hole.

[0052] like Figure 1 As shown, during the construction of the cement block 9, four anchors 8 are placed at the four corners of the cement block 9. After the cement block 9 is fixed, the four connecting columns 7 of the traffic signal controller of this utility model are inserted into the four anchors 8. At this time, the groove of the connecting column 7 is aligned with the second through hole. The four second through holes are tightened with set screws 83. The entry end of the set screw 83 enters the groove of the connecting column 7, and the traffic signal controller is fixed and cannot be separated from the cement block 9. The traffic signal controller is installed stably. Example 4:

[0053] The following is the structure of the lightning protection device for traffic signal controllers:

[0054] The traffic signal controller circuit is also equipped with a lightning protection device 13. The lightning protection device 13 includes a base housing and a plug housing that can be snapped together to form an electrically conductive structure; the base housing has an inlet terminal portion 131 and an outlet terminal portion 132 and a pushing device 133, and the inlet terminal portion 131 and the outlet terminal portion 132 are disconnected; the plug housing is provided with a switching mechanism 135 that can connect the inlet terminal portion 131 and the outlet terminal portion 132, the lower end of the switching mechanism 135 can extend into the base housing and abut against the pushing device 133, and after the switching mechanism 135 extends into the base housing, the inlet terminal portion 131 and the outlet terminal portion 132 form a circuit.

[0055] The housing is also equipped with an alarm transmitter unit 134.

[0056] After the lightning protection device experiences an overcurrent, its processor immediately controls the pusher 133 to lift the switching mechanism 135, thereby disconnecting the power input terminal 131 and the power output terminal 132. At the same time, the alarm transmitting unit 134 with a self-powered battery transmits a signal to the backend server.

[0057] In summary, this invention changes the material of the cabinet, using a cold-rolled steel shell to increase its impact resistance. The cabinet also undergoes anti-static treatment. The heat dissipation system of the traffic signal controller is improved to prevent dust from entering the cabinet, and a moisture-proof structure is added to the air intake. A lightning protection device is added to prevent damage to internal components.
