Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinets, in particular to an unmanned control cabinet for a road crossing. Background Art

[0002] The control cabinet is a closed or semi-closed metal cabinet or screen that is assembled with switchgear, measuring instruments, protective electrical appliances and auxiliary equipment according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, be easy to inspect and repair, and not endanger the safety of people and surrounding equipment. In normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of failure or abnormal operation, the circuit can be cut off or alarmed with the help of protective electrical appliances. Various parameters in operation can be displayed by measuring instruments, and some electrical parameters can be adjusted to give prompts or send signals for deviations from normal working conditions.

[0003] A Chinese patent with publication number "CN 210957362 U" discloses "an unattended electrical control cabinet", including a cabinet body, a lock is fixedly installed on the left side of the front of the cabinet body, and electrical equipment is placed inside the cabinet body, a support rod is fixedly installed on the back of the cabinet body, two support legs are fixedly installed on the bottom of the support rod, and a rain cover is fixedly installed on the top of the support rod, a solar panel is fixedly installed on the right side of the top of the rain cover, and a camera is fixedly installed on the right side of the bottom of the rain cover. The unmanned electrical control cabinet achieves the purpose of unattended operation by being provided with a camera, an alarm light and a pressure sensor. The camera is aimed at the switch door of the cabinet and can record every person passing by. When someone tries to forcibly break into the cabinet and the cabinet door is knocked open, the pressure sensor is squeezed by external force and the alarm light will be triggered to alarm, thereby achieving the purpose of warning. Since the patent achieves the purpose of unattended operation by using a camera, an alarm light and a pressure sensor, it does not have an anti-theft function for the cabinet itself and can only serve as a warning. Therefore, electrical equipment is still subject to theft and damage. The cabinet adopts upper exhaust for heat dissipation. However, in heavy rain, the waterproof cover installed on the top cannot completely protect against rain. A small amount of rainwater will enter the guide spiral disk from the heat dissipation holes exposed on the side and enter the interior of the cabinet, causing damage to the electrical appliances. For this reason, we propose an unmanned control cabinet for the crossing. Utility Model Content

[0004] The purpose of the utility model is to provide an unattended control cabinet for a level crossing, so as to solve the problem proposed in the above-mentioned background technology that the cabinet itself has no anti-theft function and can only serve as a warning, so that electrical equipment is still subject to theft and damage; in heavy rain, the waterproof cover installed on the top cannot completely protect against rain, and a small amount of rainwater will enter the guide spiral disk through the heat dissipation holes exposed on the side and enter the interior of the cabinet, causing damage to the electrical equipment.

[0006] As a further description of the above technical solution:

[0007] A connecting pipe is fixedly connected inside the base, and exhaust pipes are fixedly connected to the left and right sides and the rear side of the top of the base, and the exhaust pipes are communicated with the connecting pipe.

[0008] As a further description of the above technical solution:

[0009] The exhaust duct is in an inverted U shape, and a protective net is fixedly connected to the end of the exhaust duct.

[0010] As a further description of the above technical solution:

[0011] The filler is foam concrete, and shutters are fixedly connected to the upper sides of the left and right side walls of the cabinet. The shutters and the cabinet are an integrally formed structure, and a dustproof net is fixedly connected to the outer side wall of the shutters.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The unattended control cabinet at the crossing uses a pressure sensor installed on the limit strip on the inner side of the frame. When the cabinet door is damaged, the cabinet door triggers the pressure sensor, which starts the electric push rod. The electric push rod starts to drive the turntable to rotate. The rotation of the turntable drives the locking rod to extend and retract. The locking rod is limited and extended under the action of the limit ring, so that the end of the locking rod is inserted into the locking ring inside the cabinet body, and the entire cabinet door is locked and fixed. The foam concrete filler filled inside the cabinet door does not affect the weight of the cabinet door while also improving the strength of the cabinet door, so that the control cabinet can have an anti-theft function to prevent electrical equipment from being stolen and damaged.

[0018] 2. The unattended control cabinet for the crossing installs the exhaust system at the bottom of the cabinet, starts the exhaust fan, and cooperates with the shutters on the cabinet to let in air. The exhaust fan discharges the air inside the cabinet into the connecting pipe, and the connecting pipe discharges the air through the exhaust duct arranged on the base. This does not affect the exhaust inside the cabinet, but also prevents rainwater from entering the cabinet in bad weather, thereby preventing damage to internal electrical components caused by rainwater.
