Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway locomotive technology, and in particular to a temperature control system for locomotives. Background Technology
[0002] As the core transportation tool of rail transit, the environmental control of the driver's cab of railway locomotives directly affects the working comfort and operational safety of the crew. Traditionally, cab environmental regulation mainly relies on air conditioning systems, which control the cabin temperature through cooling or heating cycles. Currently, railway locomotives generally adopt a temperature threshold-triggered air conditioning control strategy, that is, when the temperature inside the cab exceeds the set upper limit, the cooling cycle is activated; when the temperature inside the cab falls below the set lower limit, the heating cycle is activated; and when the temperature inside the cab is either below the set upper limit or above the set lower limit, the air conditioning system is shut down.
[0003] With technological advancements, double-layer cabs have gradually become the mainstream design due to their superior sound and heat insulation properties. A double-layer cab consists of a driving space and a mezzanine. The aforementioned temperature threshold-triggered air conditioning control strategy in double-layer cabs reveals the following problems: After cooling is turned off, the mezzanine, with its better heat insulation, forms a temperature gradient with the driving space. Warm, humid air from the driving space enters the mezzanine through structural gaps. Upon encountering the cooler mezzanine walls, water vapor condenses, forming condensate. Long-term accumulation of condensate may lead to structural corrosion, electrical short circuits, and other safety hazards. Current technology lacks effective control methods, relying solely on periodic manual inspection and maintenance, failing to achieve proactive prevention. Utility Model Content

[0057] like Figures 1-3 As shown, one embodiment of the present invention provides a temperature control system for a locomotive. The locomotive includes a double-layer cab 100 and an equipment room 200. The double-layer cab 100 includes a mezzanine 1001 and a driving space 1002. The temperature control system of the locomotive includes a temperature control device 300, a first ventilation duct 1, a second ventilation duct 2, and a first regulating device 3. Temperature control device 300 is installed in equipment room 200. One end of first ventilation duct 1 is connected to temperature control device 300, and the other end of first ventilation duct 1 is connected to driving space 1002. Temperature control device 300 can generate gas at a preset temperature. First ventilation duct 1 and driving space 1002 have a connected state and a closed state. When connected, gas at the preset temperature is delivered to driving space 1002 through first ventilation duct 1. One end of second ventilation duct 2 is connected to first ventilation duct 1, and the other end of second ventilation duct 2 is connected to interlayer 1001. Temperature control device 300 can deliver gas to second ventilation duct 2. First regulating device 3 is configured to regulate the connection and disconnection between first ventilation duct 1 and second ventilation duct 2.
[0058] When the temperature inside the driver's compartment 1002 needs to be adjusted, the temperature control device 300 generates gas at a preset temperature. At this time, the first ventilation duct 1 is connected to the driver's compartment 1002, and the first regulating device 3 adjusts the connection between the first ventilation duct 1 and the second ventilation duct to be disconnected. The gas at the preset temperature can only be delivered into the driver's compartment 1002 through the first ventilation duct 1 to provide a comfortable environment for the driver. When the temperature inside the driver's compartment 1002 does not need to be adjusted, the first ventilation duct 1 is closed to the driver's compartment 1002, and the first regulating device 3 adjusts the connection between the first ventilation duct 1 and the second ventilation duct 2. At this time, the temperature control device 300 can deliver gas. Since the first ventilation duct 1 is closed to the driver's compartment 1002 and the first ventilation duct 1 is connected to the second ventilation duct 2, the gas delivered by the temperature control device 300 will directly enter the interlayer 1001 through the second ventilation duct 2. By supplying gas into the interlayer 1001, the gas pressure inside the interlayer 1001 is made slightly higher than the gas pressure inside the driving space 1002, thus creating a slightly positive pressure state inside the interlayer 1001. Since gas always flows from the area of high pressure to the area of low pressure, the warm and humid gas inside the driving space 1002 is difficult to enter the interlayer 1001 through the structural gaps, and therefore will not condense and accumulate in the interlayer 1001.
[0059] The locomotive temperature control system provided by this utility model, after adjusting the temperature of the driver's space 1002 through the first ventilation duct 1, uses the temperature control device 300 and the second ventilation duct 2 to blow air into the interlayer 1001 to form a slight positive pressure, which effectively prevents warm and humid air from the driver's space 1002 from entering the interlayer 1001, thereby avoiding the generation of condensate from the source and preventing safety hazards such as structural corrosion and electrical short circuits caused by condensate. This improves the safety and reliability of locomotive operation and extends the service life of the locomotive.
[0060] It is understood that the locomotive can be any locomotive with a double-decker cab 100 in the prior art. In this embodiment, the locomotive is a railway locomotive with a double-decker cab 100.
[0061] It should be noted that the driving space 1002 is connected to the equipment room 200 through a return air duct, and the equipment room 200 has a fresh air inlet. The temperature control device 300 is an air conditioning unit. The specific structure and working principle of the air conditioning unit can refer to the existing technology, and this embodiment does not limit it.
[0062] Specifically, a first shut-off valve is provided between the first ventilation duct 1 and the driver's space 1002, and the connection state and the closed state between the first ventilation duct 1 and the driver's space 1002 are switched by adjusting the opening and closing of the first shut-off valve.
[0063] In one optional embodiment, the first regulating device 3 is a second shut-off valve, which regulates the connection and disconnection between the first ventilation duct 1 and the second ventilation duct 2 by adjusting the opening and closing of the second shut-off valve.
[0064] In another alternative embodiment, such as Figure 2 , Figure 3 As shown, at least one side of the first ventilation duct 1 is a plane 11, and an opening 111 is provided on the plane 11. The opening 111 connects the first ventilation duct 1 and the second ventilation duct 2. The first adjusting device 3 includes a blocking plate 31 and a driving mechanism. The blocking plate 31 is slidable along a first direction and is fitted against the plane 11. The blocking plate 31 slides along the first direction to block or open the opening 111. The driving mechanism is configured to drive the blocking plate 31 to slide along the first direction. At least one side of the first ventilation duct 1 is a plane 11 with an opening 111, and the blocking plate 31 is slidably fitted against the plane 11. When the blocking plate 31 is in the blocking position, it can fit tightly against the plane 11 to form a good sealing effect, ensuring that the gas at the preset temperature generated by the temperature control device 300 can only be transported through the first ventilation duct 1. The driving mechanism can drive the sealing plate 31 to slide along the first direction, easily and precisely controlling the opening and closing degree of the opening 111. It can not only completely connect or completely cut off the gas flow between the first ventilation duct 1 and the second ventilation duct 2, but also adjust the size of the opening 111 to a certain extent, thereby controlling the gas flow rate entering the interlayer 1001. The first direction is... Figures 2-4 The X direction in the equation.
[0065] In this embodiment, the cross-section of the first ventilation duct 1 is square.
[0066] Optionally, the first adjustment device 3 further includes a guide component, which is configured to guide the sealing plate 31 to slide along the first direction. By setting the guide component, the sealing plate 31 can only produce displacement along the first direction under the drive of the drive mechanism, and will not shake, thus ensuring the stability of the movement of the sealing plate 31.
[0067] Optionally, the guide assembly includes a slidingly engaged guide rail and a slider. The guide rail extends along a first direction, and one of the sealing plate 31 and the plane 11 is connected to the guide rail, while the other is connected to the slider. It should be noted that the specific arrangement depends on actual needs, and this embodiment does not limit it.
[0068] Optionally, such as Figure 2As shown, the driving mechanism includes two sets of retractable components 321, multiple connecting strips 322, and a driving component. The two sets of retractable components 321 are spaced apart along a first direction, and extend along a second direction. The retractable components 321 are rotatably mounted on plane 11 around the second direction. The sealing plate 31 is located between the two sets of retractable components 321, and the second direction is perpendicular to the first direction. The connecting strips 322 extend along the first direction, and at least one connecting strip 322 is provided between the sealing plate 31 and each of the two sets of retractable components 321. One end of the connecting strip 322 is fixed to the sealing plate 31, and the other end is fixed to the retractable component 321. The driving component is configured to drive the retractable components 321 to rotate around the second direction, thereby causing the sealing plate 31 to slide along the first direction. The second direction is... Figures 2-4 in the Y direction.
[0069] Two sets of retractable components 321 are installed at intervals along a first direction on the plane 11 of the first ventilation duct 1 and can rotate around a second direction perpendicular to the first direction. The sealing plate 31 is located between the two sets of retractable components 321 and is connected to the two sets of retractable components 321 respectively through multiple connecting strips 322. When it is necessary to change the position of the sealing plate 31 to control the state of the opening 111, the drive component provides power to the retractable components 321. For example, if the sealing plate 31 needs to slide to the left along the first direction, under the action of the drive component, the retractable component 321 located on the left rotates to retract the connecting strips 322 to pull the sealing plate 31 to slide to the left along the first direction; if the sealing plate 31 needs to slide to the right along the first direction, under the action of the drive component, the retractable component 321 located on the right rotates to retract the connecting strips 322 to pull the sealing plate 31 to slide to the right along the first direction. The drive component drives the retracting component 321 to rotate, thereby pulling the sealing plate 31 to slide. This makes the movement of the sealing plate 31 more stable and less prone to shaking or vibration, thus improving the stability and reliability of the first adjustment device 3.
[0070] Understandably, when the sealing plate 31 needs to slide to the left along the first direction, the retracting component 321 on the right side can actively rotate under the drive of the driving component to release the connecting strip 322, or it can passively rotate under the drive of the sealing plate 31 to release the connecting strip 322; when the sealing plate 31 needs to slide to the right along the first direction, the retracting component 321 on the left side can actively rotate under the drive of the driving component to release the connecting strip 322, or it can passively rotate under the drive of the sealing plate 31 to release the connecting strip 322.
[0071] Optionally, such as Figure 3As shown, the winding assembly includes a mounting frame 3211, a plurality of receiving cylinders 3212, and a connecting shaft 3214. The mounting frame 3211 is fixedly connected to the plane 11. The plurality of receiving cylinders 3212 are spaced apart from the mounting frame 3211 along a second direction. Each receiving cylinder 3212 has an outlet. A winding roller 3213 is placed inside the receiving cylinder 3212. A connecting strip 322 is wound onto the winding roller 3213. The free end of the connecting strip 322 is pulled out from the outlet and fixed to the sealing plate 31. The connecting shaft 3214 extends along the second direction and is fixed to the plurality of winding rollers 3213. The drive assembly is configured to drive the connecting shaft 3214 to rotate around the second direction. The mounting bracket 3211 is fixed on the plane 11 of the first ventilation duct 1, providing stable support for the entire winding assembly; the housing 3212 contains the winding roller 3213, and the connecting strip 322 is wound onto the winding roller 3213, so that the housing 3212 provides a certain protection for the connecting strip 322, preventing the connecting strip 322 from being contaminated by the external environment and extending the service life of the connecting strip 322; the connecting shaft 3214 connects several winding rollers 3213 together, so that the drive assembly can drive all the winding rollers 3213 to rotate synchronously through the connecting shaft 3214, so that the winding and unwinding actions of each connecting strip 322 are consistent, thereby making the sealing plate 31 uniformly stressed and move smoothly during the sliding process, reducing problems such as jamming and shaking caused by uneven stress.
[0072] In this embodiment, as Figure 3 As shown, there are two receiving cylinders 3212, which are located at both ends of the mounting frame 3211 along the second direction. Each receiving cylinder 3212 includes a cylinder body 32121 and a cover plate 32122. The cover plate 32122 is detachably fastened to the cylinder body 32121 for easy replacement of the take-up roller 3213 and the connecting strip 322.
[0073] In some embodiments, the drive assembly includes two drive members 3231, which are used to drive the two take-up and take-down assemblies 321 to rotate respectively.
[0074] In this embodiment, as Figure 2 , Figure 3As shown, the drive assembly includes a drive member 3231 and a transmission member. The drive member 3231 is configured to drive one of the take-up and release components 321 to rotate about a second direction. The two take-up and release components 321 are connected by the transmission member, and the rotation of one take-up and release component 321 can synchronously drive the rotation of the other take-up and release component 321. With the help of the transmission member, the drive member 3231 can drive the rotation of one take-up and release component 321 to precisely and synchronously drive the rotation of the other take-up and release component 321, so that the take-up and release lengths of the connecting strips 322 connected to the two take-up and release components 321 are consistent, ensuring the stability of the sliding of the sealing plate 31. The rotation of two take-up and release components 321 can be driven by a single drive member 3231, reducing the number of parts, simplifying the overall structure, and reducing costs.
[0075] In one alternative embodiment, such as Figure 2 As shown, the transmission component includes a first pulley 32321, a second pulley 32322, and a transmission belt 32323. The first pulley 32321 is fixed to one take-up / delivery assembly 321, and the second pulley 32322 is fixed to another take-up / delivery assembly 321. The transmission belt 32323 is tensioned and sleeved on the first pulley 32321 and the second pulley 32322. Specifically, the first pulley 32321 and the second pulley 32322 are respectively fixed on two connecting shafts 3214.
[0076] In another alternative embodiment, the transmission component includes a first sprocket, a second sprocket, and a chain. The first sprocket is fixed to a take-up / retractor assembly 321, the second sprocket is fixed to another take-up / retractor assembly 321, and the chain is sleeved on the first and second sprockets. Specifically, the first and second sprockets are respectively fixed to two connecting shafts 3214.
[0077] Optionally, such as Figure 3 As shown, the fixed end of the drive component 3231 is fixed to the mounting plate, and the output end of the drive component 3231 extends along the second direction. A first gear 32311 is fixed to the output end of the drive component 3231, and a second gear 3214 is provided on the connecting shaft 3214 of a take-up and put-down assembly 321. The first gear 32311 and the second gear 32141 mesh. Rotation of the output end of the drive component 3231 drives the connecting shaft 3214 to rotate around the second direction through the meshing of the first gear 32311 and the second gear 32141.
[0078] Optionally, such as Figure 4 , Figure 5As shown, a second adjusting device 4 is detachably installed at one end of the second ventilation duct 2. The second adjusting device 4 is used to connect or block the first ventilation duct 1 and the second ventilation duct 2. When the second ventilation duct 2 needs to be cleaned or maintained, the first ventilation duct 1 and the second ventilation duct 2 can be isolated by the second adjusting device 4 to avoid affecting the gas transport inside the first ventilation duct 1 due to the disassembly of the second ventilation duct 2. Furthermore, the second adjusting device 4, together with the first adjusting device 3, can achieve a double sealing effect, more effectively preventing the gas inside the first ventilation duct 1 from being discharged outward through the opening 111 when the second ventilation duct 2 is removed.
[0079] In one alternative embodiment, such as Figure 6 As shown, the second adjusting device 4 includes a housing 41, a baffle plate 42, and a rotating shaft 43. The housing 41 has a channel 4111, one end of which is connected to the first ventilation duct 1, and the other end of which is connected to the second ventilation duct 2. The baffle plate 42 is rotatably disposed in the housing 41 and located inside the channel 4111. The baffle plate 42 rotates to switch between a first state and a second state. In the first state, the channel 4111 is unobstructed, and in the second state, the channel 4111 is blocked. The rotating shaft 43 is rotatably disposed in the housing 41 and is fixedly connected to the baffle plate 42. At least a portion of the rotating shaft 43 extends to the outside of the housing 41.
[0080] When it is necessary to connect the first ventilation duct 1 and the second ventilation duct 2, the operator rotates the shaft 43 extending to the outside of the outer casing 41. Since the shaft 43 is fixedly connected to the baffle plate 42, the rotation of the shaft 43 will cause the baffle plate 42 to rotate as well. When the baffle plate 42 rotates to the first state, the channel 4111 is unobstructed, and the first and second ventilation ducts are connected. When it is necessary to block the first ventilation duct 1 and the second ventilation duct 2, the operator rotates the shaft 43 extending to the outside of the outer casing 41. When the baffle plate 42 rotates to the second state, the channel 4111 is blocked, and the first and second ventilation ducts are disconnected. The connection and blockage of the channel 4111 are achieved by rotating the shaft 43 to drive the baffle plate 42 to rotate, which is simple and quick to operate.
[0081] Optionally, such as Figure 6As shown, the second adjusting device 4 also includes an adjusting handle 44 and an indicator pin 45. The adjusting handle 44 is located at one end of the rotating shaft 43 outside the housing 41. The indicator pin 45 is fixed to the outer wall of the housing 41. The adjusting handle 44 has a groove 441, and the indicator pin 45 is located in the groove 441. The adjusting handle 44 is provided with a scale 442, which is distributed along the extension direction of the groove 441. By holding the adjusting handle 44 to drive the rotating shaft 43 to rotate, it is more ergonomic, comfortable to hold, and makes the rotation operation more effortless. By setting the scale 442 and the indicator pin 45, when adjusting the handle 44, the rotation angle of the adjusting handle 44 can be accurately known by observing the value of the scale 442 corresponding to the indicator pin 45, thereby accurately controlling the position of the blocking plate 42 in the channel 4111. The operator only needs to observe the position of the indicator pin 45 to quickly and accurately know whether the blocking plate 42 is in the first state or the second state, which improves work efficiency and operational accuracy.
[0082] In this embodiment, as Figure 6 As shown, the outer shell 41 includes an outer shell body 411 and an outer frame 412. The outer frame 412 is fixedly connected to one side of the outer shell body 411. The rotating shaft 43 extends out of the outer frame 412. The indicator pin 45 is fixed to the outer frame 412. One side of the adjusting handle 44 is attached to the outer frame 412.
[0083] In one alternative embodiment, such as Figure 6 As shown, a sealing strip 421 is provided on the outer periphery of the baffle plate 42. The sealing strip 421 can fit tightly between the outer periphery of the baffle plate 42 and the inner wall of the channel 4111, ensuring that gas will not leak out when the baffle plate 42 is in the second state, and the sealing performance is good. The sealing strip 421 can be made of rubber.
[0084] In another optional embodiment, the second regulating device 4 is a third shut-off valve, which connects or blocks the first ventilation duct 1 and the second ventilation duct 2 by regulating the opening and closing of the third shut-off valve.
[0085] Optionally, such as Figure 4 , Figure 5 As shown, the temperature control system of this locomotive also includes a pipe adapter 5. The outer shell 41 of the second regulating device 4 is connected to the first ventilation duct 1 through the pipe adapter 5. The pipe adapter 5 corresponds to the position of the opening 111 and is fixedly connected to the plane 11 of the first ventilation duct 1.
