Technical Field

[0001] This utility model belongs to the field of maintenance door technology, specifically a maintenance door structure, a cooling tower, and a rail vehicle. Background Technology

[0002] Converters and transformers on rail vehicles are typically cooled by cooling towers. Radiators, as key components of these towers, are prone to accumulating dust, catkins, and other debris over long-term operation, leading to decreased heat dissipation efficiency. Therefore, cooling towers usually have removable maintenance doors on their outer walls for easy inspection and maintenance of the radiators.

[0003] In related technologies, the maintenance doors used in cooling towers are connected to the outer wall of the cooling tower by multiple bolts. However, when inspecting and maintaining the radiators inside the cooling tower, these bolts must be removed one by one, and then reinstalled one by one after the inspection and maintenance is completed. This makes opening and closing the maintenance doors cumbersome, inconvenient, and time-consuming. Moreover, the radiators inside the cooling tower generally require cleaning once a month, and the cleaning frequency needs to be increased, especially during the pollen season, which seriously affects the efficiency of inspection and maintenance. In addition, some maintenance doors use a snap-fit ​​connection structure with the cooling tower door frame, such as the structure disclosed in patent authorization announcement number CN206856710U. Due to the small spacing of the slots at the lower end of the maintenance door and the presence of the sealing ring, a large amount of pressing force is required to install the maintenance door properly when reinstalling it, resulting in a poor user experience.

The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Firstly, please refer to Figure 1-5As shown, this utility model embodiment provides a maintenance door structure, including a main body 100, a door body 200 and at least one hinge mechanism 300, and the main body 100 has an entrance / exit 101.

[0026] The hinge mechanism 300 includes a first connector 310, a second connector 320, and a hinge assembly 330. The first connector 310 is connected to the main body 100, and the second connector 320 is connected to the door body 200, which is close to the first connector 310.

[0027] A hinge assembly 330 is disposed on one of the first connector 310 and the second connector 320. At least a portion of the hinge assembly 330 is driven to move along a first direction to connect with the other of the first connector 310 and the second connector 320, allowing the door 200 to rotate about an axis parallel to the first direction to close or open the entrance 101. At least a portion of the hinge assembly 330 is also driven to move away from the first direction to disengage from the other of the first connector 310 and the second connector 320.

[0028] In this embodiment, the main body 100 can be part of the side wall of a cooling tower or part of other equipment that requires the installation of maintenance doors. The main body 100 is provided with an entrance 101, which can be square, round, irregular in shape, etc., to facilitate the passage of maintenance personnel.

[0029] In this embodiment, the door 200 is used to open or close the entrance 101. It can be formed by bending and welding aluminum alloy plates, and is roughly in the shape of a rectangular thin plate structure.

[0030] The hinge mechanism 300 in this embodiment includes a first connector 310, a second connector 320, and a hinge assembly 330. Both the first connector 310 and the second connector 320 can be connecting plates, connecting blocks, etc. The first connector 310 can be connected to the main body 100 near the entrance 101 by means of screwing, snapping, welding, etc. The second connector 320 can also be connected to the edge of the door 200 near the first connector 310 by means of screwing, snapping, welding, etc.

[0031] The hinge assembly 330 is used to form a hinge structure between the first connector 310 and the second connector 320. In one example, such as... Figure 3 As shown, the hinge assembly 330 is connected to the first connector 310, and its axis is arranged along a first direction, such as along... Figure 3 As shown in the positive X-axis direction, the drive hinge assembly 330 or a portion thereof moves along the first direction to connect with the second connector 320 to form a hinge structure, allowing the door 200 to rotate relative to the main body 100 to close or open the entrance 101. The axis of rotation is arranged along or parallel to the first direction.

[0032] Furthermore, the drive hinge assembly 330 or a portion thereof moves in the opposite direction along the first direction to disengage from the second connector 320, thereby facilitating the removal and placement of the door 200 aside. Thus, the application of the maintenance door structure provided in this embodiment of the invention facilitates the opening and closing of the maintenance door, enabling convenient inspection and maintenance of the radiators inside the cooling tower. It also facilitates flexible assembly and disassembly of the maintenance door from the cooling tower. Removing the maintenance door prevents damage when personnel enter or exit through the entrance 101, saving maintenance time. The operation is simple and convenient.

[0033] In another example, not shown in the figure, the hinge assembly 330 can also be connected to the second connector 320, with its axis arranged along the first direction, such as along... Figure 3 As shown in the reverse direction of the X-axis, the drive hinge assembly 330 or a portion thereof can move in the opposite direction of the first direction to connect with the first connector 310, thereby forming a hinge structure. This allows the door 200 to rotate relative to the main body 100 to close or open the entrance 101. The axis of rotation is arranged in the opposite direction of the first direction or parallel to the first direction.

[0034] In some embodiments, the hinge assembly 330 includes a hinge member 331 and an elastic member 332. The first connector 310 has a first insertion hole 311 arranged along a first direction, and the second connector 320 has a second insertion hole 321 arranged along the first direction.

[0035] Both the hinge 331 and the elastic member 332 are inserted into one of the first socket 311 and the second socket 321. The elastic member 332 drives the hinge 331 to move toward the other of the first socket 311 and the second socket 321 and elastically press against it.

[0036] Specifically, such as Figure 3 As shown, the hinge 331 can be a pivot, pin, etc. The first connector 310 has a first insertion hole 311, and the second connector 320 has a second insertion hole 321. The first insertion hole 311 and the second insertion hole 321 are coaxial and both are arranged along the first direction.

[0037] In one example, such as Figure 3 As shown, both the hinge 331 and the elastic element 332 are inserted into the first socket 311. One end of the elastic element 332 is connected to the hinge 331, and the other end of the elastic element 332 can be connected to the inner wall of the first socket 311. It can also drive the hinge 331 to move toward the second socket 321 and elastically press against it, thereby preventing the hinge 331 from automatically disengaging from the second socket 321 and ensuring the stability of the connection.

[0038] In another example, not shown in the figure, both the hinge 331 and the elastic member 332 are inserted into the second socket 321. One end of the elastic member 332 is connected to the hinge 331, and the other end of the elastic member 332 can be connected to the inner wall of the second socket 321. It can drive the hinge 331 to move toward the first socket 311 and elastically press against it, thereby preventing the hinge 331 from automatically disengaging from the first socket 311 and ensuring the stability of the connection.

[0039] Furthermore, in this embodiment, the hinge assembly 330 also includes a limiting member 333, which is inserted together with a portion of the hinge member 331 and the elastic member 332 into one of the first socket 311 and the second socket 321. The limiting member 333 is located on the side opposite to the other of the first socket 311 and the second socket 321.

[0040] The hinge 331 has a limiting protrusion 301, and the elastic member 332 is sleeved on the hinge 331. One end of the elastic member 332 abuts against the limiting protrusion 301, and the other end abuts against the limiting member 333.

[0041] Specifically, the elastic element 332 can be a spring, and the limiting element 333 is used to limit the elastic element 332; it can be a nut, a plug, etc. In one example, such as... Figure 3 As shown, the limiting member 333, together with part of the hinge member 331 and the elastic member 332, is inserted into the first insertion hole 311. The limiting member 333 is located on the side opposite to the second insertion hole 321. The hinge member 331 has a limiting protrusion 301, such as a protruding ring or a protruding post. The elastic member 332 is sleeved on the hinge member 331. One end of the elastic member 332 abuts against the limiting protrusion 301, and the other end abuts against the limiting member 333, thereby elastically pressing the hinge member 331 toward the second insertion hole 321, which is convenient for manufacturing and installation.

[0042] In another example (not shown in the figure), the limiting member 333, along with part of the hinge member 331 and the elastic member 332, are inserted into the second insertion hole 321. The limiting member 333 is located on the side opposite to the first insertion hole 311. The hinge member 331 has a limiting protrusion 301, such as a protruding ring or a protruding post. The elastic member 332 is sleeved on the hinge member 331, with one end abutting against the limiting protrusion 301 and the other end abutting against the limiting member 333, thereby elastically pressing the hinge member 331 towards the first insertion hole 311. This can be determined according to actual needs, and this embodiment does not impose too many restrictions.

[0043] Furthermore, in this embodiment, the limiting member 333 is provided with a through hole 302 arranged along the first direction, and one end of the hinge member 331 passes through the through hole 302.

[0044] Specifically, such as Figure 3As shown, when the hinge 331, elastic member 332 and limiting member 333 are inserted into the first insertion hole 311, the through hole 302 is coaxial with the first insertion hole 311 and located on the side away from the second insertion hole 321. At this time, the end of the hinge 331 away from the second insertion hole 321 passes through the through hole 302, which makes it easy to manually pull the hinge 331 to move and disengage, which is convenient for operation.

[0045] However, when the hinge 331, elastic member 332, and limiting member 333 are all inserted into the second insertion hole 321, the through hole 302 is coaxial with the second insertion hole 321 and located on the side opposite to the first insertion hole 311. In this case, the end of the hinge 331 opposite to the first insertion hole 311 passes through the through hole 302, which also facilitates manual pulling of the hinge 331 to achieve disengagement, making operation convenient. In this embodiment, no further restrictions are imposed on this aspect.

[0046] Furthermore, the limiting member 333 is connected to the inner wall of the corresponding first insertion hole 311 or second insertion hole 321 by a thread.

[0047] Specifically, such as Figure 3 As shown, the first insertion hole 311 has an internal thread on the side opposite to the limiting protrusion 301, and the limiting member 333 has an external thread that matches the internal thread. When the limiting member 333 is inserted into the first insertion hole 311, it is connected by the thread, which facilitates screwing, installation, adjustment, etc.

[0048] Of course, other types of limiting or locking structures can also be used between the limiting member 333 and the first insertion hole 311. This embodiment does not impose too many restrictions on this.

[0049] Furthermore, there are two hinge mechanisms 300, which are opposite to each other and spaced apart along the first direction.

[0050] Specifically, such as Figure 2 As shown, the two hinge mechanisms 300 are arranged opposite each other and spaced apart along the first direction. This ensures the stability of the rotational connection between the door body 200 and the main body 100, and also ensures that the door body 200 will not move along the first direction or in the opposite direction and will not detach from the main body 100 on its own.

[0051] In some embodiments, at least one door lock 210 is provided on one of the body 100 and the door 200, the door lock 210 being located on the side opposite to the hinge assembly 330.

[0052] When the door 200 closes the entrance 101, the door lock 210 is used to lock the main body 100 and the door 200 or to unlock them.

[0053] In one example, such as Figure 2As shown, three or more or fewer door locks 210 are provided on the side of the door body 200 away from the hinge assembly 330. The door locks 210 are arranged at intervals in a direction parallel to the first direction. When the door body 200 closes the entrance 101, the door locks 210 can lock the main body 100 and the door body 200, or unlock them to ensure safety.

[0054] In another example, not shown in the figure, the door lock 210 can also be located on the side of the main body 100 away from the hinge assembly 330. When the door 200 closes the entrance 101, the door lock 210 can lock the main body 100 and the door 200, or unlock them, to ensure security. This embodiment does not impose too many restrictions on this.

[0055] In some embodiments, the door 200 is provided with a viewing area 220. In this way, as... Figure 2 As shown, the degree of contamination of the radiator inside the cooling tower can be observed through the viewing area 220 without opening the door 200. The viewing area 220 can be a transparent glass panel or similar material installed on the door 200.

[0056] And / or, a sealing element 230 is provided on one of the main body 100 and the door body 200, and when the door body 200 closes the entrance 101, the sealing element 230 abuts against the other of the main body 100 and the door body 200 to seal the entrance 101.

[0057] For example, such as Figure 4 , Figure 5 As shown, the sealing element 230 can be a sealing ring, which can be glued or snapped onto the surface of the door 200 facing the main body 100. When the door 200 is closed and the door 200 seals the entrance 101, the sealing element 230 abuts against the outer side of the main body 100 to seal the entrance 101.

[0058] Of course, the sealing element 230 can also be glued or snapped onto the outer surface of the main body 100. When the door 200 is closed and the door 200 seals the entrance 101, the sealing element 230 abuts against the surface of the door 200 facing the main body 100 to seal the entrance 101.

[0059] Secondly, such as Figure 1 As shown, this embodiment of the present invention also provides a cooling tower, including a cooling tower body 10 and a maintenance door structure provided in any of the above embodiments, with the main body 100 located on the cooling tower body 10. The radiator is disposed inside the cooling tower body 10.

[0060] Therefore, the cooling tower provided by this utility model embodiment, by configuring a maintenance door structure, facilitates the opening or closing of the maintenance door, making it convenient to inspect and maintain the radiator inside the cooling tower. On the other hand, it facilitates the flexible disassembly and assembly of the maintenance door and the cooling tower. After removing the maintenance door, it can prevent personnel from damaging the maintenance door when entering or exiting through the entrance 101, saving maintenance time. It is simple to operate and convenient to use.

[0061] Thirdly, this utility model embodiment also provides a rail vehicle, including the cooling tower provided in any of the above embodiments. The cooling tower can be used to cool the converter and / or transformer.

[0062] Specifically, the coolant of the converter and transformer can be connected to the radiator in the cooling tower through pipes, pumps and other components to form a circulation loop, thereby cooling the coolant of the converter and transformer through the radiator.

[0063] Therefore, the rail vehicle provided in this embodiment of the utility model is equipped with a cooling tower. The cooling tower is equipped with a maintenance door structure, which on the one hand makes it easy to rotate and open or close the maintenance door, so as to facilitate the inspection and maintenance of the radiator inside the cooling tower. On the other hand, it facilitates the flexible disassembly and assembly of the maintenance door and the cooling tower. After the maintenance door is removed, it can prevent the maintenance door from being damaged when personnel enter or exit from the entrance 101, thus saving maintenance time. It is simple to operate and easy to use.

[0064] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
