Description

Technical Field

[0001] This utility model belongs to the technical field of ETC control cabinets and relates to an ETC gantry system control cabinet. Background Technology

[0002] The existing ETC gantry system includes a lane control system, RSU (Roadside Unit) devices, video image recognition equipment, network transmission equipment, network security equipment, and a power supply system. The lane control system, network transmission equipment, network security equipment, and power supply system all need to be installed in a control cabinet, which serves a protective function, preventing damage that could cause the ETC gantry system to collapse. The existing control cabinet is secured using nuts that mate with pre-embedded bolt posts in the ground and pre-drilled bolt holes on the cabinet. However, the existing control cabinet is relatively large, requiring a forklift or crane to lift it during installation before aligning the bolt holes and posts. The small size of the bolt holes and posts makes installation cumbersome.

[0003] Although the control cabinet disclosed in Chinese Patent No. CN221531861U uses a structure of base, support seat and limit plate to install the cabinet, which simplifies the alignment operation during hoisting and improves installation efficiency to some extent, the fasteners such as bolts and nuts used for fixing are completely exposed to the external environment. Under the long-term effects of sun and rain and temperature changes, these metal parts are very prone to rusting and aging, making disassembly and maintenance difficult, or even impossible to disassemble due to rust. The exposed standard nuts can be removed with general tools, making them easy targets for theft and damage by criminals. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an ETC gantry system control cabinet in which all bolts and nuts are concealed.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The ETC gantry system control cabinet includes a cabinet body and a base. The base has a first through hole that corresponds to a bolt post embedded in the ground. The first through hole extends vertically through the base. The base has a first connecting plate and a second connecting plate that extend upwards. The first connecting plate and the second connecting plate are arranged parallel or perpendicular to each other. Both the first connecting plate and the second connecting plate are attached to the inner wall of the cabinet body and are connected to the cabinet body through an internal connecting structure. The first through hole is located inside the cabinet body.

[0007] During installation, first align the first through hole on the base with the bolt post pre-embedded in the ground, then place the base on the ground. At this time, the bolt post will pass through the upper end of the first through hole. Then, fix the base to the ground by tightening the lock nut connected to the bolt post with threads. Lift the cabinet and place it on the base from top to bottom. Open the cabinet door and fix the first connecting plate to the cabinet from the inside through the internal connecting structure. Fix the second connecting plate to the cabinet.

[0008] In the aforementioned ETC gantry system control cabinet, the first connecting plate and the second connecting plate are parallel to each other. The base also has an upwardly extending third connecting plate and a fourth connecting plate. The third connecting plate is perpendicular to the first connecting plate and abuts against the inner wall of the cabinet. The fourth connecting plate is perpendicular to the second connecting plate and also abuts against the inner wall of the cabinet. Both the third and fourth connecting plates are connected to the cabinet via internal connecting structures. Because the cross-section of the cabinet's inner cavity is rectangular, four connecting plates are provided, each abutting against a different inner wall of the cabinet, improving the reliability of the connection.

[0009] In the aforementioned ETC gantry system control cabinet, the upper part of the side of the first connecting plate that is in contact with the inner wall of the cabinet is provided with a first guide slope, the upper part of the side of the second connecting plate that is in contact with the inner wall of the cabinet is provided with a second guide slope, the upper part of the side of the third connecting plate that is in contact with the inner wall of the cabinet is provided with a third guide slope, and the upper part of the side of the fourth connecting plate that is in contact with the inner wall of the cabinet is provided with a fourth guide slope.

[0010] During the process of placing the cabinet from top to bottom, the first guide ramp, the second guide ramp, the third guide ramp, and the fourth guide ramp can guide the cabinet to the correct position.

[0011] In the aforementioned ETC gantry system control cabinet, the first connecting plate, the third connecting plate, the second connecting plate, and the fourth connecting plate are connected together as a single unit.

[0012] The first connecting plate, the third connecting plate, the second connecting plate, and the fourth connecting plate form an annular connecting flange, and the first through hole is located inside the cabinet. Due to the presence of the first guide slope, the second guide slope, the third guide slope, and the fourth guide slope, the lateral dimension of the annular flange at the guide slope gradually increases from top to bottom.

[0013] In the aforementioned ETC gantry system control cabinet, the internal connection structure includes second through holes on each connecting plate, threaded holes on the inner wall of the cabinet, and locking bolts that pass through the second through holes and are threadedly connected to the threaded holes. The second through holes on the first connecting plate correspond one-to-one with the threaded holes on the inner wall of the cabinet that abuts against the first connecting plate; the second through holes on the second connecting plate correspond one-to-one with the threaded holes on the inner wall of the cabinet that abuts against the second connecting plate; the second through holes on the third connecting plate correspond one-to-one with the threaded holes on the inner wall of the cabinet that abuts against the third connecting plate; and the second through holes on the fourth connecting plate correspond one-to-one with the threaded holes on the inner wall of the cabinet that abuts against the fourth connecting plate. The second through holes and threaded holes extend horizontally and are perpendicular to the extension direction of the first through holes.

[0014] In the aforementioned ETC gantry system control cabinet, the cabinet has a first plate, a second plate perpendicularly connected to the first plate, a third plate perpendicularly connected to the second plate, and a fourth plate perpendicularly connected to the third plate. The fourth plate is perpendicularly connected to the first plate, and an opening is provided on the fourth plate with its bottom higher than the fourth connecting plate. A cabinet door for closing the opening is provided at the opening.

[0015] The outer side of the first connecting plate is attached to the inner side of the first plate, the outer side of the second connecting plate is attached to the inner side of the third plate, the outer side of the third connecting plate is attached to the inner side of the second plate, and the outer side of the fourth connecting plate is attached to the inner side of the fourth plate. The bottom of the opening is higher than the fourth connecting plate to prevent the fourth connecting plate from interfering with the installation of equipment.

[0016] In the aforementioned ETC gantry system control cabinet, a base plate is provided inside the cabinet, supported by a first connecting plate, a second connecting plate, a third connecting plate, and a fourth connecting plate. The upper surface of the base plate is flush with the bottom of the opening. The base plate covers all bolt posts, lock nuts, and locking bolts, preventing them from being affected by the environment.

[0017] In the aforementioned ETC gantry system control cabinet, the base has four sides, each of which is coplanar with the four sides of the cabinet body. The lateral dimension of the base is equal to the lateral dimension of the cabinet body, and the cross-sectional shapes of the two are identical, resulting in a unified overall appearance.

[0018] Compared with existing technologies, the control cabinet of this ETC gantry system has the following advantages:

[0019] The locking bolts used to secure the cabinet to the base, and the locking nuts used to secure the base to the foundation, are all sealed inside the cabinet and covered by the bottom plate. This effectively prevents these critical fasteners from being exposed to the external environment for extended periods, greatly reducing rust and aging problems caused by sun exposure, rain, and temperature changes. This makes subsequent maintenance and disassembly simple and reliable. At the same time, this concealed design completely eliminates the possibility of disassembly from the outside using common tools, thereby effectively preventing theft and damage by criminals and greatly improving the safety and stability of the entire ETC gantry system.
