Description

Technical Field

[0001] This utility model relates to the technical field of railway signal control equipment, and in particular to a protection cabinet for a computer interlocking system. Background Technology

[0002] Computerized interlocking systems are core equipment for railway signal control, and their protection cabinets must operate stably in harsh environments over long periods. Due to the adverse effects of large temperature differences, high humidity, dust, and vibration on railway lines, the protection cabinets must possess high durability and reliability to ensure the equipment is protected from external influences. In terms of design, the protection cabinets must have excellent sealing, heat dissipation capabilities, and protective measures to ensure the stable operation of the computerized interlocking system under high loads, thus guaranteeing the safety and smooth operation of railway transportation.

[0003] A search revealed an existing patent (publication number: CN214057573U) disclosing a computer interlocking system protection cabinet. The cabinet has a cable control plate fixedly installed near the wiring port, which encloses the port. The control plate has multiple slots, each containing a cable management plate that slides into it. Each cable management plate has multiple through holes, and the control plate has multiple wiring holes corresponding to these through holes. Each cable management plate has two symmetrically integrated limiting blocks at one end, and each slot has two symmetrically formed limiting grooves on its inner wall for inserting the limiting blocks. This utility model relates to the field of computer protection technology and solves the problem of low cable maintenance efficiency in existing computer interlocking system protection cabinets.

[0004] However, in the above solutions, if the equipment is used outdoors for a long time, the unidirectional heat dissipation design may not be able to effectively solve the heat dissipation problem of electrical components inside the cabinet. Since heat is usually concentrated in a heat dissipation channel in one direction, the heat cannot be quickly diffused or fully dissipated, resulting in excessively high temperature inside the cabinet. Electrical components operating in a high-temperature environment for a long time will not only increase power consumption, but also accelerate component aging, leading to a decline in the performance of electrical components or failure. Especially under frequent use, the durability and reliability of the equipment will be seriously affected, which may lead to increased maintenance costs, or even equipment downtime or functional failure. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a computer interlocking system protection cabinet. The computer interlocking system protection cabinet includes a cabinet body 1. The inner bottom wall of the cabinet body 1 has a second heat dissipation hole 7 that communicates with the outside. The interior of the second heat dissipation hole 7 has a rotating rod 2 with a length equal to the width of the cabinet body 1. The two ends of the rotating rod 2 are fixed with spiral blades 3 that fit against the inner side wall of the second heat dissipation hole 7. The bottom of the cabinet body is provided with a second heat dissipation hole with a rotating rod and spiral blades, which effectively blocks external dust from entering while ensuring ventilation, and avoids dust accumulation inside the equipment from affecting the performance of electrical components. A magnetically pleasing cabinet door 4 is installed on one side of the cabinet body 1. The magnetically pleasing cabinet door facilitates quick opening and closing of the cabinet body, is convenient to operate, and has good sealing performance. The side of the cabinet body 1 away from the cabinet door 4 has a first heat dissipation hole 5 that communicates with the outside. The first heat dissipation hole is located on the back of the cabinet body, forming an air convection channel, preventing the cabinet body from becoming a closed space, and improving the natural heat dissipation efficiency. Positioning heat dissipation components 6 are provided on both sides of the cabinet body 1.

[0028] The positioning heat dissipation component 6 includes a negative pressure fan 601, which is fixedly connected to one side of the cabinet 1. Air guide pipes 602 are fixed to the output ends of the negative pressure fan 601 on both sides to actively guide the airflow in a directional manner, concentrate heat dissipation for high-heat areas, and improve heat dissipation efficiency. A square block 603 is fixed to one end of the air guide pipe 602. Electric pulleys 604 are provided on both sides of the square block 603. The square block can be driven by electricity to slide vertically, flexibly adjust the heat dissipation position, and adapt to the heat dissipation needs of different electrical components. Telescopic baffles 605 are provided at the upper and lower ends of the square block 603. The end of the telescopic baffle 605 away from the square block 603 is fixedly connected to the side wall of the cabinet 1. It automatically extends and retracts when the square block moves, always covering the opening of the square slot to prevent dust intrusion, thus taking into account both dynamic heat dissipation and dust prevention.

[0029] Square grooves 103 are provided on both sides of the cabinet 1. The two sides of the square block 603 are fitted with the inner side of the square groove 103, and the square block 603 is slidably connected to the inner side of the square groove 103.

[0030] T-shaped grooves 101 are provided on both sides of the square groove 103 at positions corresponding to the electric pulley 604. The cross-sectional shape of the T-shaped groove 101 is the same as that of the electric pulley 604. The surface of the electric pulley 604 is in close contact with the inner side of the T-shaped groove 101. The electric pulley 604 rolls on the inner side of the T-shaped groove 101 to ensure the stability of the square block when sliding and to avoid deviation or jamming.

[0031] Storage slots 102 are provided on both sides of the square slot 103 at the corresponding positions of the telescopic baffle 605. The width of the telescopic baffle 605 is greater than the width of the square block 603, and the width of the storage slots 102 is the same as the width of the telescopic baffle 605.

[0032] A tapered hole 6031 is provided on the inner side of the square block 603. The diameter of the end of the tapered hole 6031 near the inner wall of the cabinet 1 is smaller than the diameter of the end away from the inner wall of the cabinet 1. The change in hole diameter increases the air outlet speed and enhances the local heat dissipation intensity.

[0033] A circular piece 606 is provided at one end of the tapered hole 6031 near the inner side wall of the cabinet 1. The side wall of the circular piece 606 fits against the inner side of the tapered hole 6031. Multiple ventilation holes are provided at both ends of the circular piece 606 to further accelerate the airflow and disperse the wind pressure, avoid direct blowing and damage to components, and maintain a high wind speed.

[0034] Example 2

[0035] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the first heat dissipation hole 5 is Z-shaped and is set towards the bottom along the height direction of the cabinet 1. Through the tortuous channel design, the principle of gravity settling is used to block dust. After the dust enters, it is blocked by the Z-shaped path and slides down naturally, achieving a self-cleaning effect and reducing the maintenance frequency.

[0036] The remaining structure is the same as that in Example 1.

[0037] Based on embodiments 1-2, the working principle of this utility model is as follows: The user can quickly open or close the cabinet 1 by opening and closing the cabinet door 4. The first heat dissipation hole 5 on the back of the cabinet 1 and the second heat dissipation hole 7 at the bottom can prevent the equipment from becoming a closed space. The rotating rod 2 and the spiral blade 3 inside the second heat dissipation hole 7 can prevent external dust from entering the interior of the cabinet 1 through the second heat dissipation hole 7 while satisfying the ventilation effect. Moreover, due to the special shape of the first heat dissipation hole 5, external dust can be blocked after entering the first heat dissipation hole 5, and then naturally slide out of the inside of the first heat dissipation hole 5 due to gravity. During the use of the equipment, the positioning heat dissipation component 6 can position and dissipate heat for the electrical components inside the cabinet 1.

[0038] The electric pulley 604 drives the square block 603 to slide vertically inside the square groove 103. During the sliding of the square block 603, the telescopic baffle 605 can extend and retract adaptively to further prevent external dust from entering the interior of the cabinet 1. When the electric pulley 604 slides to the corresponding position inside the storage groove 102, the negative pressure fan 601 works, and the air duct 602 guides the air output by the negative pressure fan 601 to dissipate heat inside the cabinet 1 through the square block 603.

[0039] The airflow velocity can be effectively increased by the tapered hole 6031 inside the square block 603, and the airflow velocity can be further enhanced by the circular plate 606 at one end of the tapered hole 6031, thus effectively improving the heat dissipation efficiency.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
