Description

Technical Field

[0001] This utility model relates to the field of railway technology, specifically to an electronic interlocking cabinet for railway tracks. Background Technology

[0002] In the field of rail transit, electronic interlocking cabinets are core control equipment, and the stable operation of their internal electronic components is directly related to the safety and reliability of train dispatching.

[0003] The electronic components inside the electronic interlocking cabinet generate a lot of heat during continuous operation. If the heat dissipation is not timely or uneven, it can easily cause equipment failure.

[0004] Existing electronic interlocking cabinets mostly use fixed-direction airflow with fixed exhaust nozzle positions, which can only dissipate heat to specific areas inside the cabinet. This results in a large number of heat dissipation blind spots inside the cabinet, prominent uneven heating of electronic components, and some components being exposed to high-temperature environments for extended periods, affecting their lifespan and operational stability. Therefore, an electronic interlocking cabinet for rails is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electronic interlocking cabinet for rails, which solves the problems of fixed air outlet positions that can only dissipate heat to specific areas inside the cabinet, resulting in a large number of heat dissipation blind spots inside the cabinet, uneven heating of electronic components, and some components being in a high-temperature environment for a long time, affecting their service life and operational stability.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a cabinet and an air outlet that extends through the outer wall of the cabinet. A blower mechanism is provided inside the cabinet, and an air supply mechanism is provided on the outer wall of the cabinet.

[0007] The blower mechanism includes a blowing part and a rotating part;

[0008] The blowing part includes a connecting box and two sets of air nozzles, and the rotating part includes a rotating rod and a rotating box;

[0009] The outer wall of the connecting box is fixedly connected to the inner side of the cabinet. Two fixed tubes are fixedly provided through the outer wall of the connecting box and extend into the inside of the connecting box. Two rotating tubes are slidably sleeved on the outer walls of the two fixed tubes respectively. The outer walls of the two rotating tubes are fixedly provided through the outer walls of the two rotating boxes and extend into the inner side of the two rotating boxes respectively. The outer walls of the two sets of air outlets are fixedly provided through the outer walls of the two rotating boxes and extend into the inner side of the two rotating boxes respectively.

[0010] Preferably, the air supply mechanism includes a fixed box, the bottom surface of which is fixedly connected to the top surface of the cabinet, an air supply pipe is fixedly provided through the outer wall of the fixed box and extends to the inside of the fixed box, the side of the air supply pipe near the cabinet passes through the outer wall of the cabinet and the outer wall of the connecting box and extends to the inside of the connecting box, an air pump is fixedly provided on the outer wall of the fixed box, and the air outlet of the air pump is fixedly provided through the outer wall of the fixed box and extends to the inside of the fixed box, so that the air supply mechanism can supply air to the inside of the connecting box.

[0011] Preferably, two connecting rods are fixedly provided on the inner sides of the two rotating boxes, and the outer walls of the two connecting rods extend to the inner side of the connecting box.

[0012] Preferably, two limiting grooves are respectively opened on the inner side of the two rotating tubes, and two fixing rings are respectively fixedly sleeved on the outer wall of the two fixed tubes. The outer wall of the two fixing rings is slidably connected to the inner wall of the two limiting grooves. The two fixing rings can prevent the rotating tube from detaching from the two fixed tubes when rotating.

[0013] Preferably, a rotating rod is rotatably mounted on the inner side of the connecting box via a bearing seat. Two first bevel gears are fixedly sleeved on the outer wall of the rotating rod, and two second bevel gears are fixedly sleeved on the outer walls of the two connecting rods respectively. The tooth surfaces of the two first bevel gears mesh with the tooth surfaces of the two second bevel gears respectively. The rotation of the rotating rod drives the two first bevel gears on its outer wall to rotate. Since the first bevel gears mesh with the second bevel gears on the connecting rods, the connecting rods are driven to rotate, thereby driving the rotating box to rotate around the rotating tube as the axis.

[0014] Preferably, the top surface of the rotating rod extends sequentially through the inner side of the box, the inner side of the cabinet, and the outer wall of the fixed box to the inside of the fixed box. The top surface of the rotating rod is rotatably connected to the inner side of the fixed box through a bearing seat. An impeller is fixedly sleeved on the outer wall of the rotating rod. High-pressure airflow acts on the impeller, driving the impeller to rotate.

[0015] This utility model provides an electronic interlocking cabinet for rails. It has the following advantages:

[0016] (i) The electronic interlocking cabinet for rails has a blower mechanism that drives the rotating box to rotate around the rotating tube as the axis through the meshing transmission of the rotating rod, the first bevel gear and the second bevel gear, so that the air outlet direction of the two sets of air outlets continuously changes, breaking through the limitation of the traditional fixed air outlet direction, and can dynamically supply air to various areas inside the cabinet, effectively eliminating heat dissipation blind spots, improving the uniformity of heat dissipation inside the cabinet, and ensuring that all electronic components can be fully cooled.

[0017] (ii) In the air supply mechanism of the electronic interlock cabinet for track, when the air pump is working, it delivers high-pressure airflow into the fixed box. On the one hand, it is stably delivered to the connecting box through the air supply pipe to provide sufficient power for the air blower mechanism to output air. On the other hand, it acts on the impeller to drive the rotating rod to rotate, which drives the air outlet of the air blower mechanism to rotate. This linkage design does not require an additional drive motor, reduces energy consumption, and thus improves the overall efficiency of the heat dissipation system. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: including a cabinet 1 and an air outlet 2 through the outer wall of the cabinet 1, a blower mechanism 3 is provided on the inner side of the cabinet 1, and an air supply mechanism 4 is provided on the outer wall of the cabinet 1.

[0026] The blower mechanism 3 includes a blowing part and a rotating part;

[0027] The blowing part includes a connecting box 31 and two sets of air outlets 33, and the rotating part includes a rotating rod 35 and a rotating box 32;

[0028] The outer wall of the connecting box 31 is fixedly connected to the inner side of the cabinet 1. Two fixed tubes 37 are fixedly installed through the outer wall of the connecting box 31, extending into the interior of the connecting box 31. Two rotating tubes 38 are slidably sleeved on the outer walls of the two fixed tubes 37 respectively. The outer walls of the two rotating tubes 38 are fixedly installed through the outer walls of the two rotating boxes 32 respectively, extending into the interior of the two rotating boxes 32. Two sets of air outlets 33 are fixedly installed through the outer walls of the two rotating boxes 32 respectively, extending into the interior of the two rotating boxes 32. Two connecting rods 310 are fixedly installed on the inner sides of the two rotating boxes 32 respectively. The walls extend to the inner sides of the two connecting boxes 31 respectively. Two limiting grooves are opened on the inner sides of the two rotating tubes 38 respectively. Two fixing rings 39 are fixedly sleeved on the outer walls of the two fixing tubes 37 respectively. The outer walls of the two fixing rings 39 are slidably connected to the inner walls of the two limiting grooves respectively. A rotating rod 35 is rotatably set on the inner side of the connecting box 31 through a bearing seat. Two first bevel gears 34 are fixedly sleeved on the outer wall of the rotating rod 35. Two second bevel gears 36 are fixedly sleeved on the outer walls of the two connecting rods 310 respectively. The tooth surfaces of the two first bevel gears 34 mesh with the tooth surfaces of the two second bevel gears 36 respectively.

[0029] The air supply mechanism 4 includes a fixed box 41, the bottom surface of which is fixedly connected to the top surface of the cabinet 1. An air supply pipe 42 is fixedly installed through the outer wall of the fixed box 41 and extends to the inside of the fixed box 41. The side of the air supply pipe 42 near the cabinet 1 passes through the outer wall of the cabinet 1 and the outer wall of the connecting box 31 and extends to the inside of the connecting box 31. An air pump 44 is fixedly installed on the outer wall of the fixed box 41. The air outlet end of the air pump 44 passes through the outer wall of the fixed box 41 and extends to the inside of the fixed box 41. The top surface of the rotating rod 35 passes through the inner side of the connecting box 31, the inner side of the cabinet 1 and the outer wall of the fixed box 41 and extends to the inside of the fixed box 41. The top surface of the rotating rod 35 is rotatably connected to the inner side of the fixed box 41 through a bearing seat 2. An impeller 43 is fixedly sleeved on the outer wall of the rotating rod 35.

[0030] In use, the air supply mechanism 4 provides the power source for the airflow circulation of the entire cabinet. When the air pump 44 is started, it draws in external air and delivers it into the fixed box 41, creating a high-pressure airflow environment inside the fixed box 41. The high-pressure airflow acts on the impeller 43, driving the impeller 43 to rotate, which in turn drives the rotating rod 35, which is fixedly connected to the impeller 43, to rotate synchronously. On the other hand, the high-pressure airflow is delivered to the connecting box 31 through the air supply pipe 42, providing the airflow basis for the air outlet of the blower mechanism 3.

[0031] Driven by the air supply mechanism 4, the blower mechanism 3 delivers air at multiple angles. After receiving the airflow from the air supply pipe 42 inside the connecting box 31, the airflow enters the rotating pipe 38 through the fixed pipe 37 and is further delivered into the rotating box 32. Finally, it is discharged through the air outlet 33 on the outer wall of the rotating box 32 to dissipate heat from the electronic components inside the cabinet 1. At the same time, the rotation of the rotating rod 35 drives the two first bevel gears 34 on its outer wall to rotate. Since the first bevel gears 34 mesh with the second bevel gears 36 on the connecting rod 310, the connecting rod 310 is driven to rotate, which in turn drives the rotating box 32 to rotate around the rotating pipe 38 as the axis. This rotation process causes the air outlet direction of the air outlet 33 to change continuously, expanding the air supply range and improving the uniformity of heat dissipation inside the cabinet 1.
