Description

Technical Field

[0001] This utility model relates to the field of railway logistics transportation technology, and in particular to a microcomputer interlocking device for railway logistics. Background Technology

[0002] In railway logistics transportation, a fully electronic computer interlocking system is indispensable, which includes interlocking machines, meter readers, monitoring machines, electrical maintenance machines, distribution cabinets, control consoles, interface frames, and relay circuits.

[0003] Console → Interlocking Machine: The dispatcher inputs instructions (such as route arrangement) through the console, and the interlocking machine generates control commands after performing logical verification;

[0004] Interlocking machine → Executor: The interlocking machine sends control commands to the execution machine, which then drives the field equipment to perform actions;

[0005] Interlocking Machine → Interlocking Machine: The interlocking machine feeds back the equipment status (such as turnout in position, signal light on) to the interlocking machine in real time for interlocking logic updates;

[0006] Monitoring unit → Interlocking unit / Execution unit: The monitoring unit obtains data from the interlocking unit and execution unit, displays the real-time status, and records the operation log;

[0007] Electrical maintenance unit → Interlocking unit / monitoring unit: The maintenance unit regularly backs up data, analyzes fault records, and supports remote maintenance;

[0008] Power distribution cabinet → All equipment: Provides power support for all equipment to ensure continuous system operation;

[0009] Interface frame: Serves as a communication bridge, ensuring high-speed and stable data transmission between devices.

[0010] Generally, interlocking machines, meter reading machines, electrical maintenance machines, distribution cabinets, and interface racks are all housed in a heat dissipation cabinet, which is equipped with a cooling fan for heat dissipation, and heat dissipation is achieved through the exchange of internal and external air.

[0011] In real-world applications, when the air entering the heat exchanger contains moisture, the following problems may occur:

[0012] 1. Moisture in the air combines with oxygen and pollutants (such as sulfides and chlorides) to form an electrolyte on the circuit board, causing electrochemical corrosion of metal parts (such as copper wires and solder joints), degrading the performance of electronic components (such as capacitors and resistors), and consequently reducing the computing power of the interlocking machine and the meter reader, thus reducing work efficiency.

[0013] Second: Moisture provides a growth environment for mold. Mold may grow on or inside the equipment. The acidic substances secreted by the mold can corrode the equipment shell and internal components, thereby affecting the operating efficiency of the entire interlocking system.

[0014] Therefore, this application provides a microcomputer interlocking device for railway logistics to meet the requirements. Utility Model Content

[0015] The purpose of this application is to provide a microcomputer interlocking device for railway logistics, which solves the technical problem that the efficiency of the existing computer interlocking system is reduced due to moisture entering the heat dissipation cabinet.

[0016] To achieve the above objectives, this application provides the following technical solution: a microcomputer interlocking device for railway logistics, comprising a control console, a monitoring unit, and an interlocking machine, a meter reader, an electrical maintenance machine, a power distribution cabinet, and an interface frame, all housed in a heat dissipation cabinet. The heat dissipation cabinet is equipped with an exhaust pipe and an intake pipe with a cooling fan installed inside. Both the exhaust pipe and the intake pipe are connected to an annular mounting cover composed of a first cover and a second cover, and communicate with the inner cavity of the annular mounting cover. A rotatable bearing is rotatably mounted at the axis of the annular mounting cover. A rotating shaft is fitted with an inner ring that is sealed and fixed on it. An outer ring is provided around the inner ring. Both ends of the inner and outer rings are provided with intercepting meshes. The two intercepting meshes form a material storage gap with the inner and outer rings. Granular desiccant is placed in the material storage gap. An air inlet channel and an air outlet channel are provided on the outer wall of the annular mounting cover, which are aligned with the positions of the air inlet pipe and the air outlet pipe. The air inlet channel and the air outlet channel are located on both sides of the vertical axis of the annular mounting cover and are arranged vertically.

[0017] In a preferred embodiment of this invention, a plurality of partitions are arranged circumferentially between the two opposing interception nets, and the two ends of the plurality of partitions are respectively sealed and fixed to the inner ring and the outer ring, forming a filling cavity between two adjacent partitions;

[0018] A second elastic ring and a first elastic ring are respectively provided on both ends of the inner ring and the outer ring. A plurality of elastic spacers are arranged circumferentially between the second elastic ring and the first elastic ring, and the plurality of elastic spacers are arranged in a one-to-one correspondence with the plurality of partitions.

[0019] As a preferred embodiment of this invention, a magnetic assist unit is also included to assist in driving the outer ring to rotate rapidly, thereby improving dehumidification efficiency.

[0020] As a preferred embodiment of this embodiment, the magnetic assist unit includes a first mounting ring mounted on the upper outer ring and a second mounting ring mounted inside the annular mounting cover.

[0021] The first mounting ring is provided with a plurality of first magnetic isolation blocks arranged in a circular and inclined manner, and a first permanent magnet is installed in the groove of the plurality of first magnetic isolation blocks;

[0022] A second magnetic shielding block is inclinedly arranged on the second mounting ring, and a second permanent magnet is installed in the groove of the second magnetic shielding block. The outer magnetic poles of the second permanent magnet are opposite to those of the first permanent magnet.

[0023] The second permanent magnet is located on one side of the vertical axis of the annular mounting cover and is arranged corresponding to the air intake channel.

[0024] In summary, the technical effects and advantages of this utility model are as follows:

[0025] 1. The structure of this utility model is reasonable. The heat dissipation cabinet of this microcomputer interlocking equipment uses desiccant to absorb moisture in the intake gas, and then dries the water-absorbing gas through the heat-absorbing gas. After the desiccant absorbs water, the gravity distribution is uneven, causing the desiccant in the filling cavity to rotate, thereby making the desiccant recyclable. This reduces the impact of moisture on the working efficiency of the equipment and also reduces the dehumidification cost.

[0026] 2. In this utility model, a magnetic assist unit is also provided, the purpose of which is to increase the rotation speed of the outer ring, promote the replacement of dry and wet desiccants, and facilitate efficient dehumidification of the gas. Attached Figure Description

[0035] 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.

[0036] Example: Reference Figure 1-3 The microcomputer interlocking device for railway logistics shown includes a control console 6, a monitoring unit 7, and an interlocking unit 1, a meter reader 2, an electrical maintenance unit 3, a power distribution cabinet 4, and an interface frame 5, all housed in a heat dissipation cabinet 8. The heat dissipation cabinet 8 is equipped with an exhaust pipe 16 and an intake pipe 10 containing a cooling fan. Both the exhaust pipe 16 and the intake pipe 10 are connected to an annular mounting cover composed of a first cover 11 and a second cover 12, and communicate with the inner cavity of the annular mounting cover. A rotating shaft 1 is rotatably mounted at the axis of the annular mounting cover via a sealed bearing 18. 7. An inner ring 9 is sealed and fixed on the rotating shaft 17, and an outer ring 15 is provided around the inner ring 9. Both sides of the inner ring 9 and the outer ring 15 are provided with intercepting mesh 22, and the two intercepting meshes 22 form a material storage gap with the inner ring 9 and the outer ring 15. Granular desiccant is provided in the material storage gap. An air inlet channel 13 and an air outlet channel 14 are provided on the outer wall of the annular mounting cover, which are aligned with the positions of the air inlet pipe 10 and the air outlet pipe 16. The air inlet channel 13 and the air outlet channel 14 are located on both sides of the vertical axis of the annular mounting cover and are arranged vertically.

[0037] During operation, the cooling fan is activated, and gas enters the annular mounting hood through the inlet air passage 13. After absorbing moisture through the granular desiccant corresponding to the inlet of the inlet pipe 10, the gas enters the heat dissipation cabinet 8 through the inlet pipe 10 to dissipate heat from the internal equipment. The heated gas is discharged into the annular mounting hood through the outlet pipe 16, and after passing through the granular desiccant corresponding to the outlet of the outlet pipe 16, it is discharged through the outlet air passage 14. During this process, the heated gas can heat the granular desiccant after it has absorbed water, causing the moisture in the desiccant to be carried away and discharged through the outlet air passage 14. Because the granular desiccant near the inlet air passage 13 becomes heavier after absorbing water, and because the inlet air passage 13 and the outlet air passage 14 are located on both sides of the vertical axis of the annular mounting hood and are perpendicular to each other... The vertical arrangement causes the outer ring 15 to rotate clockwise. As the granular desiccant continues to absorb water and gain weight, the outer ring 15 will slowly drive the internal granular desiccant to rotate. At the same time, the water-absorbing granular desiccant will move to the air outlet of the air outlet pipe 16 for heating and dehumidification, thus reducing the weight of this part of the granular desiccant. This eventually forms a cycle. During the rotation of the outer ring 15 due to the uneven distribution of gravity after water absorption, the desiccant will be dried after absorbing water, thus forming a cycle that allows the desiccant to be reused continuously. During the rotation, the corresponding desiccant at the air inlet channel 13 is constantly rotating and changing position, so that the dried desiccant can continuously replace the water-absorbing desiccant, thereby improving the dehumidification efficiency and ensuring the efficient operation of the entire microcomputer interlocking equipment.

[0038] It should be noted that there are air gaps between the stacked granular desiccants.

[0039] As a preferred embodiment of this example, Figure 3-5 As shown, multiple partitions 23 are arranged in a circular pattern between two oppositely arranged interception nets 22. The two ends of the multiple partitions 23 are sealed and fixed to the inner ring 9 and the outer ring 15 respectively, and a filling cavity is formed between two adjacent partitions 23.

[0040] A second elastic ring 21 and a first elastic ring 19 are respectively provided on both ends of the inner ring 9 and the outer ring 15. Multiple elastic spacers 20 are arranged in a circle between the second elastic ring 21 and the first elastic ring 19, and the multiple elastic spacers 20 are arranged in a one-to-one correspondence with multiple partitions 23.

[0041] Multiple partitions 23 are provided, along with elastic spacers 20, second elastic rings 21, and first elastic rings 19 (all of which slide against the inner wall of the annular mounting cover). The purpose is to form multiple independent and sealed filling cavities, while utilizing the sealing effect of elastic spacers 20, second elastic rings 21, and first elastic rings 19 to prevent air leakage.

[0042] During operation, gas enters through the inlet channel 13, passes through the corresponding filling chamber, and then enters the inlet pipe 10. The drying particles in this filling chamber dehumidify the incoming gas. The dehumidified gas can directly enter the inlet pipe 10, preventing the incoming gas from entering other filling chambers through diffusion. This ensures the drying of the desiccant in other filling chambers, which is beneficial for the rapid water absorption (improving the gas dehumidification effect) and rapid weight gain (accelerating the rotation of the outer ring 15, which helps to speed up the replacement of the desiccant and further improve the dehumidification effect). It also prevents the gas with moisture from spreading in the annular mounting cover, causing all the desiccant to absorb water at the same time. Similarly, when the gas with heat is discharged, it will pass through the corresponding filling chamber and be dried. This prevents the gas with heat from spreading in the annular mounting cover and drying the desiccant in all filling chambers (drying the desiccant in a single or two adjacent filling chambers is more beneficial for the rapid drying of the desiccant in a single or two filling chambers).

[0043] It should be noted that when the baffle 23 moves within the corresponding range of the air intake channel 13, when it enters the annular mounting cover from the air intake channel 13, it will pass through the two adjacent filling cavities and eventually enter the air intake pipe 10.

[0044] As a preferred embodiment of this invention, a magnetic assist unit is also included to assist in driving the outer ring 15 to rotate rapidly, thereby improving dehumidification efficiency.

[0045] The purpose is to increase the rotation speed of the outer ring 15, promote the replacement of dry and wet desiccants, and facilitate efficient dehumidification of the gas.

[0046] As a preferred embodiment of this example, Figure 3 and Figure 4 As shown, the magnetic assist unit includes a first mounting ring 24 mounted on the upper outer ring 15 and a second mounting ring 26 mounted inside the annular mounting cover.

[0047] Multiple first magnetic isolation blocks are arranged in a circular and inclined manner on the first mounting ring 24, and a first permanent magnet 25 is installed in the groove of the multiple first magnetic isolation blocks.

[0048] A second magnetic shielding block is inclinedly provided on the second mounting ring 26, and a second permanent magnet 27 is installed in the groove of the second magnetic shielding block. The outer magnetic poles of the second permanent magnet 27 are opposite to those of the first permanent magnet 25.

[0049] The second permanent magnet 27 is located on one side of the vertical axis of the annular mounting cover and is correspondingly arranged with respect to the air intake channel 13.

[0050] When the outer ring 15 rotates, the magnetic attraction of the first permanent magnet 25 and the second permanent magnet 27 causes the outer ring 15 to rotate rapidly to a certain angle and then stop (at this time, the first permanent magnet 25 just passes the second permanent magnet 27 through magnetic attraction and inertia). As the desiccant in the corresponding filling cavity absorbs water and becomes heavier, the outer ring 15 rotates slowly. After rotating and moving a certain angle (try to keep this angle within a small range), the rotation of the outer ring 15 is accelerated again by magnetic force (while rotating, the internal stirring shaft 24 also stirs the desiccant). This can speed up the replacement of dry and wet desiccant, and also has a good stirring effect on the corresponding desiccant, thereby accelerating the dehumidification of the air and the dehumidification of the desiccant.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
