Description

Technical Field

[0001] This utility model belongs to the field of rail transit, specifically relating to a monorail moving mechanism, a rail inspection device, and an inspection system. Background Technology

[0002] my country's railway construction has achieved remarkable success, with a railway network stretching across the land like a giant dragon. From the early days of the People's Republic of China when the country had only 22,000 kilometers of railway lines, nearly half of which were inoperable, to today's operational railway network exceeding 160,000 kilometers, including over 46,000 kilometers of high-speed rail.

[0003] In the rapid development of railways, regular maintenance and replacement of tracks are crucial to ensure the safe operation of trains. Since track replacement involves a large number of tracks and takes a considerable amount of time, the tracks to be replaced (referred to as "replacement tracks") are often placed in advance on the side of the track, and the replacement is completed during a lull period.

[0004] When replacement rails are placed on the side of the track, they are often not secured and are exposed to direct sunlight for extended periods, leading to deformation and twisting due to increased temperature. When the replacement rails become twisted or deformed, especially at high temperatures and with significant deformation, they can easily encroach into the railway track, affecting the safe passage of trains and posing a safety hazard.

[0005] To determine whether a replacement track has been deformed or twisted, existing technologies often combine satellite monitoring with manual inspection. However, the manual inspection process is inefficient and increases the workload of personnel. Therefore, to address the shortcomings of this method, the applicant has designed a track inspection device that can move along the replacement track.

[0006] The track inspection device proposed by the applicant includes a monorail moving mechanism, which comprises drive wheels symmetrically arranged on both sides. These drive wheels contact both sides of a replacement track, thereby enabling movement along the replacement track. However, in this design, because the drive wheels need to be in close contact with both ends of the replacement track, the moving mechanism can only be installed onto or detached from the end of the replacement track at a time. This obviously leads to significant inconvenience in use (for example, when stopping the inspection, one must wait for the moving mechanism to reach the end of the replacement track before detaching it), resulting in poor flexibility. Utility Model Content

[0007] This utility model provides a monorail moving mechanism, a track inspection device and an inspection system, the purpose of which is to solve the problem that the moving mechanism needs to be installed and disassembled from the end of the replacement track, which causes inconvenience in use.

[0008] To achieve the above objectives, this utility model provides a monorail moving mechanism, including...

[0009] The vehicle frame includes a first frame and a second frame, which are rotatably connected by a rotating component. Each of the first and second frames is equipped with a drive wheel module, which includes a drive wheel. The first and second frames rotate around the rotating component, causing the drive wheel to contact or separate from the replacement track.

[0010] A locking module is installed on the frame, which can lock the first frame and the second frame, so that the drive wheel remains in contact with the replacement track.

[0011] In this design, the vehicle frame is configured as a first frame and a second frame, which are rotatably connected. When the moving mechanism needs to be installed onto the replacement track, the first and second frames can be rotated to position the replacement track between them. Then, a locking module locks the first and second frames to prevent them from separating freely. When the moving mechanism needs to be separated from the replacement track, the locking module unlocks the first and second frames, and then the first and second frames are rotated to separate them from the replacement track.

[0012] The above design allows the moving mechanism to be installed on the replacement track at any position, and also allows the moving mechanism to be separated from the replacement track at any position, thus overcoming the shortcomings of the existing technology.

[0013] Preferably, in order to ensure that the locking module can lock the first rack and the second rack more stably, the locking module described in this solution is provided with at least two.

[0014] This solution uses at least two locking modules to work together to lock the first and second racks. Therefore, compared to configuring only one locking module, the connection between the first and second racks is more stable.

[0015] To ensure a more stable locking mechanism for both the first and second racks, the locking module in this design is positioned at both ends of the connection between the first and second racks.

[0016] This solution equips both ends of the connection between the first rack and the second rack with locking modules. Therefore, when the first rack and the second rack need to be fixed, both ends of the first rack and the second rack are fixed, making the first rack and the second rack more stable and preventing the first rack and the second rack from separating freely.

[0017] Preferably, the locking module in this solution is a latch lock.

[0018] Preferably, since the first frame and the second frame are rotatably connected by a connecting component, in order to prevent external impurities and rainwater from entering the connection between the first frame and the second frame, this solution also includes a shield, which is movably installed above the frame and is used to shield the top of the frame.

[0019] This solution involves installing a shield on the vehicle frame. The shield can cover the connection between the first and second frames, preventing external impurities and rainwater from entering the connection between the first and second frames.

[0020] Preferably, to avoid interference with the rotation of the first and second frames caused by the shield, the shield in this solution is rotatably mounted on the vehicle frame.

[0021] Preferably, in order to ensure greater stability of the frame, this solution also includes a driven wheel module. Both the first frame and the second frame are equipped with driven wheel modules. The driven wheel modules are arranged in front of and behind the drive wheel modules. The driven wheel module includes a driven wheel that can contact the lower end of the replacement track.

[0022] This design employs a driven wheel module and a drive wheel module that work together, positioned one in front of the other to support the front and rear of the chassis, respectively. Therefore, when the chassis moves, it is supported by both the drive wheel and driven wheel modules, resulting in greater stability and less tendency to tilt compared to a chassis equipped with only a drive wheel module.

[0023] Preferably, in order to make the moving structure more stable during movement, this solution also includes an auxiliary wheel module. Both the first frame and the second frame are equipped with auxiliary wheel modules. The auxiliary wheel module includes an auxiliary wheel that can contact the side wall of the replacement track.

[0024] This design sets the auxiliary wheel modules to contact the side walls of the replacement track. Therefore, when the moving mechanism is on the replacement track, the auxiliary wheel modules on both sides can provide support for the frame, preventing the frame from tilting or falling over during movement, making the moving mechanism move more stably.

[0025] To enable the inspection of replacement tracks, a second aspect of this utility model discloses a track inspection device, including the aforementioned monorail moving mechanism and a detection module. The detection module is installed on the monorail moving mechanism and is used to detect the status of the replacement track.

[0026] This solution uses a monorail moving mechanism as the power source to move along the replacement track. As the monorail moving mechanism moves along the replacement track, the detection module, installed within it, can detect the replacement track.

[0027] Preferably, in order to detect the replacement track, the detection module of this solution includes a camera, which is installed on the monorail moving mechanism and is used to acquire images of the replacement track.

[0028] This solution uses a camera as the detection module, which captures images of the replacement track. Then, manual evaluation based on the images determines whether the replacement track has bulged, twisted, or encroached on the track line. If such phenomena are found, workers can promptly replace the track at that location.

[0029] To enable the detection of the replacement track, the detection module of this solution includes a temperature detector, which is installed on the monorail moving mechanism and is used to collect the temperature of the replacement track.

[0030] In this solution, a temperature detector is used to monitor the temperature of the replacement track. When the temperature of the replacement track exceeds a threshold, it indicates that the track has likely experienced expansion or deformation. At this point, staff can promptly address the issue with the replacement track.

[0031] In order to enable remote staff to be informed of the status of the replacement track in a timely manner, the third aspect of this utility model provides a track inspection system, including the aforementioned track inspection device and monitoring terminal, wherein the track inspection device is signal-connected to the monitoring terminal.

[0032] In this solution, the track inspection device can collect relevant information about track replacement, and then feed this information back to the monitoring terminal. Personnel at the monitoring terminal can then promptly obtain information about the status of the inspected track based on the feedback from the track inspection device.

[0033] The beneficial effects of this utility model are as follows: In this solution, the frame is configured as a first frame and a second frame, and the first frame and the second frame are rotatably connected. When it is necessary to install the moving mechanism onto the replacement track, the first frame and the second frame can be rotated to place the replacement track between the first frame and the second frame. Then, the first frame and the second frame are locked by a locking module to prevent them from separating freely. When it is necessary to separate the moving mechanism from the replacement track, the first frame and the second frame are unlocked by the locking module, and then the first frame and the second frame are separated from the replacement track by rotating them.

[0034] The above design allows the moving mechanism to be installed on the replacement track at any position, and also allows the moving mechanism to be separated from the replacement track at any position, thus overcoming the shortcomings of the existing technology. Attached Figure Description

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0047] It should be noted that all actions involving the acquisition of signals, information, or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where the application is located, and with the authorization granted by the owner of the relevant device.

[0048] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0049] Example 1

[0050] The basics are as follows: Figure 1 To be continued Figure 2 As shown, a monorail moving mechanism can move along a replacement track and can be flexibly installed and disassembled, thereby overcoming the shortcomings of the prior art.

[0051] like Figure 3 As shown, the monorail moving mechanism in this embodiment includes a frame 1, a drive wheel module 3, a driven wheel module 4, and an auxiliary wheel module 5. The frame 1 serves as the mounting base for mounting the drive wheel module 3, the driven wheel module 4, and the auxiliary wheel module 5.

[0052] like Figure 1 and Figure 2As shown, in this embodiment, the preferred frame 1 includes a first frame 11 and a second frame 12, which are symmetrically arranged on both sides and rotatably connected by a rotating component 13. The rotating component 13 can be a hinge or other rotating components 13 in the prior art. The first frame 11 and the second frame 12 can rotate around the rotating component 13. To ensure the connection stability of the first frame 11 and the second frame 12, several rotating components 13 can be provided between them, for example, 2, 3, 4, or 5. The first frame 11 and the second frame 12 can be assembled by splicing and welding several metal plates, thereby forming a cavity inside the first frame 11 and the second frame 12, which can hold electrical components such as batteries and cables.

[0053] It should be noted that the first frame 11 and the second frame 12 are rotatably connected. Therefore, when the moving mechanism needs to be installed onto the replacement track, firstly, the first frame 11 and the second frame 12 are rotated apart. Then, the track is placed between the first frame 11 and the second frame 12. Finally, the first frame 11 and the second frame 12 are rotated closer together to install the moving mechanism onto the replacement track. When the moving mechanism needs to be removed from the replacement track, the first frame 11 and the second frame 12 are rotated apart, moving away from the replacement track. Finally, the first frame 11 and the second frame 12 are removed from the replacement track. This arrangement ensures that the moving mechanism can be installed and removed from any position on the replacement track, facilitating use and making the moving mechanism more flexible.

[0054] Since the first frame 11 and the second frame 12 are rotatably connected, in order to ensure that the first frame 11 and the second frame 12 do not automatically separate during the operation of the moving mechanism, this embodiment also configures a locking module 14 between the first frame 11 and the second frame 12. Figure 3 As shown. The locking module 14 can be used to lock or unlock the first frame 11 and the second frame 12. To ensure a more stable connection between the first frame 11 and the second frame 12, several locking modules 14 can be provided as needed, such as 2, 3, 4, or 5. In this embodiment, the locking module 14 is preferably a latch lock, with both ends of the latch lock installed on the sides of the first frame 11 and the second frame 12 respectively. The latch lock can be used to lock and unlock the first frame 11 and the second frame 12. When the first frame 11 and the second frame 12 need to rotate, the latch lock is unlocked; when the first frame 11 and the second frame 12 need to be fixedly connected, the latch lock is locked.

[0055] It should be noted that in this embodiment, the locking module 14 is set as a latch lock. However, it is obvious that in some other embodiments, the locking module 14 can also be other locking modules 14 in the prior art.

[0056] To prevent damage to the moving mechanism from hard collisions with external obstacles during movement, this embodiment includes anti-collision components at the ends of both the first frame 11 and the second frame 12. These anti-collision components are made of rubber. They provide cushioning and protection, preventing damage from hard collisions. In this embodiment, the anti-collision components can be cylindrical or rectangular blocks, and can be fastened or adhesively attached to both ends of the first frame 11 and the second frame 12, ensuring protection at both ends of the moving mechanism.

[0057] Since the first frame 11 and the second frame 12 are connected by a rotating component 13, and electrical components can also be installed inside the first frame 11 and the second frame 12, it is necessary to prevent external rainwater from corroding the rotating component 13 and causing damage to the electrical components. Figure 4 As shown, in this embodiment, the frame 1 also includes a cover 2. The cover 2 is installed on the top of the first frame 11 and the second frame 12. The cover 2 is a rectangular cover. One end of the cover 2 is installed on the outer edge of the first frame 11 via a hinge. The cover 2 can rotate around the hinge, thereby exposing the first frame 11 and the second frame 12. At the same time, a lock 21 is arranged on the opposite side of the hinge. When the cover 2 covers the top of the first frame 11 and the second frame 12, the lock 21 locks the cover 2. The lock 21 can be a latch lock.

[0058] It should be noted that when the moving mechanism is moving normally, the shield 2 covers the tops of the first frame 11 and the second frame 12 to prevent external rainwater from entering the device. When the moving mechanism needs to be removed from the replacement track, in order to prevent the shield 2 from interfering with the rotation of the first frame 11 and the second frame 12, the shield 2 must first be unlocked and rotated to a position where it does not interfere with the rotation of the first frame 11 and the second frame 12. Finally, the first frame 11 and the second frame 12 can then rotate normally.

[0059] To drive the frame 1, in this embodiment, there are two drive wheel modules 3, which are respectively installed at the lower ends of the first frame 11 and the second frame 12, as shown below. Figure 1 and Figure 2As shown. The drive wheel module 3 is in a symmetrical state, and the drive wheel modules 3 on both sides can respectively contact the lower part of the replacement track on both sides. In this embodiment, the drive wheel module 3 includes a drive wheel, a drive motor, and a reducer. The drive motor is connected to the drive wheel through the reducer, so that the drive wheel can be driven to rotate by the drive motor. In order to install the drive wheel module 3 at the lower end of the first frame 11 or the second frame 12, in practice, the drive motor and the reducer can be installed at the lower end of the first frame 11 or the second frame 12 by configuring fasteners, and then the reducer is connected to the drive wheel through a transmission shaft, thereby ensuring that the drive wheel can be stably driven. In this embodiment, the drive wheel can be a rubber wheel.

[0060] It should be noted that because the cross-section of the replacement track is roughly I-shaped, the contact point between the drive wheel and the lower part of the replacement track is an inclined surface. Therefore, to ensure a closer fit between the drive wheel and the lower end of the track, this embodiment preferably sets the outer rim of the drive wheel as an inclined surface; that is, the drive wheel as a whole is truncated cone-shaped. The inclination angle of the outer rim of the drive wheel is the same as the inclination angle of the lower part of the replacement track, allowing the drive wheel to fully fit against the lower part of the replacement track, thereby ensuring a better driving effect.

[0061] like Figures 5-7 As shown, to ensure that the frame 1 does not tilt, two driven wheel modules 4 are also provided in this embodiment, and are respectively installed at the lower ends of the first frame 11 and the second frame 12. The driven wheel modules 4 are also symmetrically arranged and are positioned in front of and behind the drive wheel modules 3 respectively. The driven wheel modules 4 on both sides can contact the lower parts of the replacement track on both sides respectively. The drive wheel modules 3 on both sides and the driven wheel modules 4 on both sides are arranged in a rectangular symmetrical manner. The drive wheel modules 3 on both sides support the front end of the frame 1, and the driven wheel modules 4 on both sides support the rear end of the frame 1.

[0062] The driven wheel module 4 in this embodiment specifically includes a mounting plate 41, a driven wheel mounting seat 42, and a driven wheel 43. The mounting plate 41 is U-shaped and is mounted on the bottom of the first frame 11 or the second frame 12 by fasteners or welding. The mounting plate 41 has two connecting holes, and a first connecting rod 44 is disposed in the connecting holes, and the first connecting rod 44 can extend and retract within the connecting holes. The driven wheel mounting seat 42 is mounted below the mounting plate 41 and is fixedly connected to the lower part of the first connecting rod 44. The driven wheel 43 is a rubber wheel and is rotatably mounted on the driven wheel mounting seat 42. At the same time, a first spring 45 is provided between the mounting plate 41 and the driven wheel mounting seat 42, and the first spring 45 is sleeved on the first connecting rod 44.

[0063] It is understandable that when the replacement track is twisted, if the driven wheel 43 is fixed, it may become suspended due to the twisting of the replacement track, thus causing the frame 1 to be unable to maintain stable movement. Therefore, this embodiment is equipped with a first spring 45 and a first connecting rod 44. The first spring 45 keeps the driven wheel 43 pressed down, thereby ensuring that the driven wheel 43 can always be in contact with the replacement track and preventing the driven wheel 43 from becoming suspended.

[0064] like Figure 7 As shown, since the cross-section of the replacement track is roughly I-shaped, the lower contact position between the driven wheel 43 and the replacement track is an inclined surface. Therefore, to ensure that the driven wheel 43 can fit more closely with the lower end of the replacement track, in this embodiment, the lower surface of the mounting plate 41 is preferably set as an inclined surface. Thus, when the driven wheel mounting seat 42 is connected to the mounting plate 41 via the connecting rod, the driven wheel mounting seat 42 is in an inclined state. The driven wheel 43 mounted on the driven wheel mounting seat 42 is also in an inclined state. The driven wheel 43, mounted in an inclined state, can fit more closely with the lower end of the replacement track, and the driven wheel 43 is in stable contact with the replacement track.

[0065] like Figure 8 and Figure 9 As shown, in this embodiment, the drive wheel module 3 and the driven wheel module 4 cooperate to drive the frame 1. However, when the replacement track is twisted, the entire drive mechanism still has the risk of tipping over. Therefore, this embodiment also configures auxiliary wheel modules 5 on the frame 1. At least three auxiliary wheel modules 5 are provided, more preferably four, arranged in a rectangular pattern. The auxiliary wheel modules 5 are located above the drive wheel module 3 and the driven wheel module 4. Of the four auxiliary wheel modules 5, two are mounted on the first frame 11 and two are mounted on the second frame 12. When the moving mechanism is on the replacement track, the auxiliary wheel modules 5 located on the first frame 11 and the second frame 12 can respectively abut against the side walls of the replacement track, thereby ensuring more stable movement of the moving mechanism and preventing tilting.

[0066] like Figure 8As shown, the auxiliary wheel module 5 in this embodiment includes a mounting block 51, an auxiliary wheel mounting seat 52, and an auxiliary wheel 53. The mounting block 51 is fixedly mounted on the side of the first frame 11 or the second frame 12. The mounting block 51 can be welded to the first frame 11 or the second frame 12. A second connecting rod 54 is disposed on the mounting block 51 and is fixedly connected to the mounting block 51. The second connecting rod 54 is in a horizontal state. The auxiliary wheel mounting seat 52 is provided with a connection port, and the end of the second connecting rod 54 is embedded in the connection port, allowing the second connecting rod 54 to extend and retract horizontally within the connection port. To prevent the second connecting rod 54 from detaching from the auxiliary wheel mounting seat 52, this embodiment also provides a limiting part at the end of the second connecting rod 54. A second spring 55 is disposed between the mounting block 51 and the auxiliary wheel mounting seat 52, and the second spring 55 is sleeved on the second connecting rod 54. Two or more second connecting rods 54 can be disposed between the mounting block 51 and the auxiliary wheel mounting seat 52, and each connecting rod is sleeved with a second spring 55. The auxiliary wheel 53 is made more stable by multiple second connecting rods 54. The auxiliary wheel 53 is rotatably mounted on the auxiliary wheel mounting base 52 and is set in a horizontal position.

[0067] Taking one application scenario as an example: when the replacement track expands and twists, the second spring 55 can push the auxiliary wheel mounting seat 52, so that the auxiliary wheel 53 is in close contact with the outer wall of the replacement track, preventing the auxiliary wheel 53 from being suspended in the air and ensuring that the auxiliary wheel 53 can be in close contact with the outer wall of the replacement track.

[0068] Example 2

[0069] This embodiment provides a track inspection device, such as Figure 10 As shown, it includes the monorail moving mechanism, detection module 6, and position detector 7 as in Embodiment 1.

[0070] In this embodiment, the monorail moving mechanism can move along the direction of the replacement track, and the detection module 6 is installed on the monorail moving mechanism. When the monorail moving mechanism moves along the direction of the replacement track, the detection module 6 detects the replacement track on the moving path. The position detector 7 is also installed on the monorail moving mechanism. The position detector 7 is mainly used to determine whether the monorail moving mechanism is about to move to the end of the track, thereby preventing the monorail moving mechanism from running off the replacement track.

[0071] The detection module 6 in this embodiment includes a camera 61 and a temperature detector 62. Two cameras 61 are configured in this embodiment, and are respectively fixedly installed at the front and rear ends of the frame 1. The cameras 61 can simultaneously capture images of the replacement track at both the front and rear ends of the frame 1, allowing remote workers to manually identify and determine if any distortion has occurred. The temperature detector 62 in this embodiment can be an infrared thermometer, installed inside the first frame 11 and / or the second frame 12. When the moving mechanism is on the replacement track, the infrared thermometer faces the outer wall of the replacement track, and can measure the temperature of the outer wall of the replacement track.

[0072] It should be noted that: in this embodiment, it is preferred to configure both the camera 61 and the temperature detector 62, but in some other embodiments, only one of the camera 61 and the temperature detector 62 may be configured. Alternatively, in some other embodiments, the detection module 6 may be other detection modules 6 in the prior art.

[0073] To prevent the moving mechanism from derailing, in this embodiment, position detectors 7 are mounted on the frame 1, and at least two position detectors 7 are configured, located at both ends of the frame 1. The position detectors 7 can be laser rangefinders, used to detect the distance between the end of the replacement track and the moving mechanism, thereby determining whether the moving mechanism has moved to the end of the replacement track. Simultaneously, to facilitate accurate detection by the laser rangefinder, this embodiment also includes a baffle at the end of the replacement track. The baffle is used for detection by the laser rangefinder. The position detectors 7 are electrically connected to the control module, which in turn is electrically connected to the drive wheel module 3 in the moving mechanism.

[0074] When position detector 7 determines that the moving mechanism has reached the end of the replacement track, the control module controls the moving wheel module to stop rotating, thus stopping the moving mechanism. Afterwards, the control module can also control the moving wheel module to rotate in the opposite direction, causing the moving mechanism to move in the opposite direction along the replacement track. This process is repeated, enabling the moving mechanism to patrol back and forth on the replacement track. The control module can be a PLC module or a microcontroller module, as is common in existing technologies.

[0075] It should be noted that in this embodiment, the position of the moving mechanism is determined using a laser rangefinder. However, in some other embodiments, the position detector 7 can be other modules available in the prior art. For example, a radar module, which detects whether the moving mechanism has moved to the end of the replacement track.

[0076] The following describes the specific working process of the track inspection device:

[0077] When a replacement track inspection is required, first rotate the shield 2 to a position where it does not interfere with the first frame 11 and the second frame 12. Then, the user can rotate the first frame 11 and the second frame 12 so that the replacement track is positioned between them, allowing the moving mechanism to be installed onto the replacement track. After the moving mechanism is installed on the replacement track, the user rotates the shield 2 back to cover the frame 1, preventing external rainwater from entering. When the moving mechanism is installed on the replacement track, it moves along the track. The detection module 6 mounted on the moving mechanism performs inspections of the replacement track. The moving mechanism can move back and forth on the replacement track, performing multiple precise inspections.

[0078] After the inspection is completed, the moving mechanism needs to be separated from the replacement track. First, rotate the shield 2 to move it to a position where it does not interfere with the first frame 11 and the second frame 12. Then, the user can rotate the first frame 11 and the second frame 12 to separate them from the replacement track.

[0079] Example 3

[0080] This embodiment provides a track anti-bulging inspection system, including the track inspection device and monitoring terminal from Embodiment 2. In this embodiment, the track inspection device and monitoring terminal are in a signal connection state. The replacement track status signal detected by the track inspection device can be sent to the monitoring terminal. The monitoring terminal can be a conventional monitoring terminal, which includes a control module, a display for user observation, and an operation panel for user operation.

[0081] In this embodiment, the monitoring terminal can be installed in the maintenance room, where relevant maintenance personnel are stationed. Once the maintenance personnel are aware of the status of the replacement track, they can promptly address any issues such as thermal expansion and distortion, or the replacement track encroaching on the track's path.

[0082] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
