Description

Technical Field

[0001] This invention relates to the field of railway track transportation technology, and in particular to a gap image acquisition device and a switch machine. Background Technology

[0002] In the field of railway track transportation technology, the condition of turnout switching equipment directly affects train safety. As an important turnout switching device, the switch machine is characterized by high switching frequency, frequent application, and significant impact on track operation after equipment failure, making it a key focus and challenge for on-site maintenance and repair.

[0003] A switch machine is an important signaling infrastructure used to reliably change the position of a turnout, change the direction of the turnout, lock the turnout switch rail, and reflect the position of the turnout. It can ensure traffic safety, improve transportation efficiency, and reduce the labor intensity of traffic operators.

[0004] For switch machines, the switch machine gap (i.e., the indicator gap) is used to reflect the contact status and position of the switch point rail (spot rail) and the stock rail (wing rail). If the switch point rail and the stock rail are not in proper contact, it may cause serious consequences such as train derailment. Therefore, in order to ensure train safety and line operation efficiency, and to reduce the number of maintenance and repairs of switch switching equipment, it is particularly important to monitor the switch machine gap in real time.

[0005] A switch machine includes two parallel indicator rods. One indicator rod has a notch at its top right end, and the other has a notch at its top left end. Above each notch is an inspection post. When the turnout is switched into position, one inspection post in the switch machine falls into the notch of the indicator rod below it. The task of the notch monitoring is to monitor the distance (i.e., the notch width, or gap width, which is the gap width between the edge of the notch of the indicator rod and the edge of the inspection post) for the notch of the indicator rod that has fallen into the inspection post.

[0006] However, the traditional gap image acquisition devices currently used on switch machines are poorly designed, which prevents operators from manually observing the gaps of the switch machine from top to bottom, thus affecting the efficiency of on-site maintenance.

[0007] Furthermore, when the camera in the gap image acquisition device malfunctions, the unreasonable structural design makes it inconvenient to install and disassemble the camera, resulting in low maintenance efficiency and failing to meet the rapid maintenance needs of switch machine users.

[0008] Therefore, there is an urgent need to develop a technology that can solve the above-mentioned technical problems. Summary of the Invention

[0009] The purpose of this invention is to address the technical deficiencies of existing technologies by providing a gap image acquisition device and a switch machine.

[0010] To this end, the present invention provides a gap image acquisition device for use on a switch machine, which includes two camera assemblies, a first mounting bracket and a second mounting bracket; The first and second mounting brackets are fixedly installed on the left and right ends of the original switch machine contact seat on the outside of the switch machine. The first and second mounting brackets are symmetrically distributed from left to right; The two camera components are respectively mounted on the first mounting bracket and the second mounting bracket; The two camera assemblies are located diagonally above the notch at the top left end of one of the original indicator poles of the switch machine and the notch at the top right end of the other indicator pole, respectively. Camera assembly, including housing and top plate; The top of the hollow, open-top shell is fitted with a top plate; A hollow cavity is formed between the housing and the top plate, and the camera module, light panel, lens cover and frosted panel are installed in the cavity. The housing includes a bottom plate, an upper side plate, and mounting lugs; The top perimeter of the bottom plate of the shell is provided with an upper side plate that protrudes upward and surrounds the perimeter. At the front and rear ends of the top of the upper side plate of the housing, there is a horizontally distributed mounting ear; The mounting ear is provided with a threaded hole for connection with the end through hole of the first upper cover plate on the first mounting bracket or the end through hole of the second upper cover plate on the second mounting bracket via a first fastener.

[0011] In addition, the present invention also provides a switch machine, which includes a gap image acquisition device as described above.

[0012] As can be seen from the technical solution provided by the present invention above, compared with the prior art, the present invention provides a gap image acquisition device and a switch machine, which is scientifically designed and highly reliable. It can reliably acquire images of gaps inside the switch machine, which helps the staff to make predictions and handle switch machine faults in advance based on video images, thereby reducing the occurrence of faults and having significant practical significance.

[0013] In this invention, the camera assembly is installed below the switch machine contact seat, not directly above it, so as not to obstruct the view of the gap inside the switch machine, not to affect manual inspection of the gap, and to facilitate daily inspection and maintenance by staff. Furthermore, the installation structure of this invention is reasonable and reliable, and installation and disassembly are convenient and quick, which is conducive to rapid maintenance and repair, and meets the rapid maintenance needs of switch machine users.

[0019] The technical solution of the present invention will be further described below through specific embodiments. Details not specified in the embodiments are all conventional technologies in the industry.

[0020] See Figures 1 to 13 The present invention provides a gap image acquisition device, which is applied to a switch machine, and includes two camera components 3, a first mounting bracket 1 and a second mounting bracket 2; The first mounting bracket 1 and the second mounting bracket 2 are fixedly installed at the left and right ends of the original switch machine contact seat 5 on the outside of the switch machine. The first mounting bracket 1 and the second mounting bracket 2 are symmetrically distributed from left to right; Two camera components 3 are respectively mounted on the first mounting bracket 1 and the second mounting bracket 2; Two camera components 3 are located diagonally above the notch at the top left end of one of the original indicator poles of the switch machine and the notch at the top right end of the other indicator pole, respectively. It should be noted that the camera assembly 3 on the first mounting bracket 1 is used to capture the image of the notch on the left side of the switch machine, that is, to capture the image of the gap between the edge of the notch groove at the top left end of the original indicator rod of the switch machine and the edge of the inspection post.

[0021] It should be noted that the camera assembly 3 on the second mounting bracket 2 is used to capture images of the notch on the right side of the switch machine, that is, to capture images of the gap between the edge of the notch groove at the top right end of the other indicator rod of the original switch machine and the edge of the inspection post.

[0022] In this invention, specifically, the camera assembly 3 on the first mounting bracket 1 is located to the upper left of the notch at the top left end of the original indicator rod of the switch machine; The camera assembly 3 on the second mounting bracket 2 is located to the upper right of the notch at the top right end of the other indicator pole of the switch machine.

[0023] In this invention, specifically, the first mounting bracket 1 and the second mounting bracket 2 are fixedly installed at the lower part of the left and right ends of the original switch contact seat 5 of the external switch machine. In this invention, specifically, the first mounting bracket 1 and the second mounting bracket 2 are respectively connected to the camera assembly 3 through two first fasteners 4 (i.e. bolts); In this invention, see Figure 6 The first mounting bracket 1 includes a first base plate 101 distributed longitudinally; The front and rear ends of the first base plate 101 are respectively provided with a first fixing plate 1011 and a second fixing plate 1012 protruding to the right. The first fixing plate 1011 and the second fixing plate 1012 are connected to the front and rear sides of the left end of the switch machine contact seat 5. In practice, the first fixing plate 1011 and the second fixing plate 1012 are connected to the left end of the switch machine contact seat 5 by two first bolts on the front and rear sides. The first fixing plate 1011 and the second fixing plate 1012 are respectively provided with a first fixing plate through hole 1013; The left end of the switch machine contact seat 5 has a first protrusion on both the front and rear sides; Each of the two first bosses has a threaded mounting hole at a position corresponding to the two first fixing plate through holes 1013 of the first fixing plate 1011 and the second fixing plate 1012. After the first bolt passes through a first fixing plate through hole 1013, it is threadedly fixed to a first boss threaded mounting hole corresponding to the position.

[0024] Furthermore, the through hole 1013 of the first fixing plate is circular in shape; It should be noted that the first fixing plate 1011 and the second fixing plate 1012 are used to connect with the switch machine contact seat 5; It should be noted that the two original first bosses on the left end of the switch machine contact seat 5 have two mounting holes (first boss threaded mounting holes) for fixing the switch machine contact seat 5 to the original bottom shell 7 of the switch machine. The design of the present invention can utilize the original mounting holes (first boss threaded mounting holes) on the two switch machine contact seats 5 to fix the first fixing plate 1011 and the second fixing plate 1012 of the first mounting bracket 1 to the switch machine contact seat 5. That is, after the bolt passes through the through hole on the first fixing plate 1011 or the second fixing plate 1012 corresponding to the position and the original mounting hole on the switch machine contact seat 5, it is threadedly fixed to the original threaded mounting hole on the bottom shell 7.

[0025] In specific implementation, the first mounting bracket 1 also includes a vertically distributed first connecting plate 102; The first connecting plate 102 is disposed at the top left end of the first base plate 101; Furthermore, a first upper cover plate 103 is provided at the top (specifically at the rear end) of the first connecting plate 102, with an inclined distribution. The camera assembly 3 is fixedly connected to the bottom of the first upper cover plate 103; The camera assembly 3 on the first upper cover plate 103 is located to the upper left of the notch at the top left end of the original indicator rod of the switch machine; Furthermore, the tilt angle of the first upper cover 103 is a specific angle, for example, 45°. This specific tilt angle is used to allow the camera assembly 3 to be aligned with the switch machine notch, obtain a clear image of the notch, and not prevent the operator from manually viewing the switch machine notch in the indicator rod notch slot from directly above the contact seat.

[0026] Furthermore, the vertical height of the first upper cover plate 103 gradually increases from left to right.

[0027] Furthermore, the front and rear ends of the first upper cover plate 103 are respectively connected to the top of the first connecting plate 102 via a first support plate 1032.

[0028] Furthermore, at the top left and right ends of the switch machine contact seat 5, directly above the notch slots at the top of the two original indicator rods of the switch machine, a viewing window 50 (i.e., a notch) is provided respectively. It should be noted that, for the present invention, when the gap image acquisition device of the present invention is applied to a switch machine (such as a ZD6 type switch machine), the top left and right ends of the switch machine contact seat 5 have two viewing windows (i.e., two horizontally distributed viewing windows 50). These viewing windows are used by workers to manually view the gap condition from above the switch machine contact seat 5 when maintaining the switch machine.

[0029] Furthermore, a circular first upper cover plate end through hole 1030 is provided at both the front and rear ends of the first upper cover plate 103; The two first upper cover plate end through holes 1030 are connected to the camera assembly 3 by two first fasteners 4.

[0030] Furthermore, a circular through hole 1031 is provided in the longitudinal middle of the first upper cover plate 103; The through hole 1031 in the center of the first upper cover is used to pass through the data cable that comes with the camera assembly 3; In specific implementation, the top front end of the first fixing plate 1011 and the top rear end of the second fixing plate 1012 of the first base plate 101 are respectively vertically provided with the first reinforcing rib 104 and the second reinforcing rib 105. Furthermore, both the first reinforcing rib 104 and the second reinforcing rib 105 are triangular in shape.

[0031] Furthermore, the bottom of the first reinforcing rib 104 is fixedly connected to the top of the first fixing plate 1011; The first connecting plate 102 is fixedly connected to the left side of the first reinforcing rib 104; Furthermore, the bottom of the second reinforcing rib 105 is fixedly connected to the top of the second fixing plate 1012; The left side of the second reinforcing rib 105 is fixedly connected to the first connecting plate 102.

[0032] It should be noted that, in this invention, the structural strength of the first mounting bracket 1 can be enhanced by the first reinforcing rib 104 and the second reinforcing rib 105.

[0033] In this invention, the second mounting bracket 2 includes a second base plate 201, a second connecting plate 202, a second upper cover plate 303, a third reinforcing rib 204, and a fourth reinforcing rib 205; It should be noted that the second mounting bracket 2 has the same structural composition as the first mounting bracket 1, and is symmetrically distributed from left to right; It should be noted that the only difference between the second mounting bracket 2 and the first mounting bracket 1 is that the positions of the cameras in the two camera assemblies 3 mounted on the second upper cover plate 203 and the first upper cover plate 103 are different. The position of the camera on the first upper cover plate 103 of the first mounting bracket 1 is further back than the position of the camera on the second cover plate 203 of the second mounting bracket 2 (because the position of the indicator rod it photographs is further back).

[0034] In this invention, see Figure 7 The second mounting bracket 2 includes a longitudinally distributed second base plate 201; The front and rear ends of the second base plate 201 are respectively provided with a third fixing plate 2011 and a fourth fixing plate 2012 protruding to the left. The third fixing plate 2011 and the fourth fixing plate 2012 are connected to the front and rear sides of the right end of the switch machine contact seat 5. In practice, the third fixing plate 2011 and the fourth fixing plate 2012 are connected to the front and rear sides of the right end of the switch machine contact seat 5 by two second bolts. The third fixing plate 2011 and the fourth fixing plate 2012 are each provided with a second fixing plate through hole 2013; The left end of the switch machine contact seat 5 has a second protrusion on both the front and rear sides; Each of the two second bosses has a threaded mounting hole at a position corresponding to the two second fixing plate through holes 2013 of the third fixing plate 2011 and the fourth fixing plate 2012. After the second bolt passes through a second fixing plate through hole 2013, it is threadedly fixed to a second boss threaded mounting hole corresponding to the position.

[0035] Furthermore, the through hole 2013 of the second fixing plate is circular in shape; It should be noted that the third fixing plate 2011 and the fourth fixing plate 2012 are used to connect with the switch machine contact seat 5; It should be noted that the two original second protrusions on the right end of the switch machine contact seat 5 have two mounting holes (second protrusion threaded mounting holes) for fixing the switch machine contact seat 5 to the original bottom shell 7 of the switch machine. The design of the present invention can utilize the mounting holes (second protrusion threaded mounting holes) originally present on the two switch machine contact seats 5 to fix the third fixing plate 2011 and the fourth fixing plate 2012 of the second mounting bracket 2 on the switch machine contact seat 5.

[0036] In specific implementation, the second mounting bracket 2 also includes a vertically distributed second connecting plate 202; The second connecting plate 202 is located at the top right end of the second base plate 201; Furthermore, a second upper cover plate 203 is provided at the top (specifically at the rear end) of the second connecting plate 202, with an inclined distribution. The camera assembly 3 is fixedly connected to the bottom of the second upper cover plate 203; The camera assembly 3 on the second upper cover 203 is located to the upper right of the notch at the top right end of the other indicator rod of the switch machine; Furthermore, the second upper cover 203 is tilted at a specific angle, such as 45°. This specific tilt angle allows the camera assembly 3 to be aligned with the switch machine notch to obtain a clear image of the notch, without hindering the operator from manually viewing the switch machine notch in the indicator rod notch slot from directly above the contact seat.

[0037] Furthermore, the vertical height of the second upper cover 203 gradually decreases from left to right.

[0038] Furthermore, the front and rear ends of the second upper cover plate 203 are respectively connected to the top of the second connecting plate 202 via a second support plate 2032.

[0039] It should be noted that, for the present invention, at the top left and right ends of the switch machine contact seat 5, a viewing window (i.e., a notch) is respectively provided above the notch slots at the top of the two original indicator rods of the switch machine; when the notch image acquisition device of the present invention is applied to a switch machine (e.g., a ZD6 type switch machine), the top left and right ends of the switch machine contact seat 5 have two viewing windows (i.e., two horizontally distributed viewing windows), which are used by the staff to manually check the notch status from above the switch machine contact seat 5 when maintaining the switch machine.

[0040] Furthermore, a circular second upper cover plate end through hole 2030 is provided at both the front and rear ends of the second upper cover plate 203; The two second upper cover end through holes 2030 are connected to the camera assembly 3 by two first fasteners 4.

[0041] Furthermore, a circular through hole 21031 is provided in the longitudinal center of the second upper cover plate 203; The through hole 21031 in the center of the second upper cover is used to pass through the data cable that comes with the camera assembly 3; In specific implementation, the top front end of the third fixing plate 2011 and the top rear end of the fourth fixing plate 2012 of the second base plate 201 are respectively vertically provided with the third reinforcing rib 204 and the fourth reinforcing rib 205. Furthermore, the third reinforcing rib 204 and the fourth reinforcing rib 205 are both triangular in shape.

[0042] Furthermore, the bottom of the third reinforcing rib 204 is fixedly connected to the top of the third fixing plate 2011; The right side of the third reinforcing rib 204 is fixedly connected to the second connecting plate 202; Furthermore, the bottom of the fourth reinforcing rib 205 is fixedly connected to the top of the fourth fixing plate 2012; The second connecting plate 202 is fixedly connected to the right side of the fourth reinforcing rib 205.

[0043] It should be noted that, in this invention, the structural strength of the second mounting bracket 2 can be enhanced by the third reinforcing rib 204 and the fourth reinforcing rib 205.

[0044] In this invention, the camera assembly 3 includes a housing 301, a top plate 302, a camera module 308, a light panel 306, a lens cover 304, a frosted panel 305, an isolation stud 307, and a second fastener 309. A top plate 302 is provided on the top of the hollow shell 301 with an open top; A hollow cavity is formed between the housing 301 and the top plate 302, and the camera module 308, the light panel 306, the lens cover 304 and the frosted panel 305 are disposed in the cavity. In specific implementation, housing 301 includes housing base plate 3011, housing upper side plate 3012 and mounting lug 3013; The top perimeter of the bottom plate 3011 is provided with an upper side plate 3012 that protrudes upward and surrounds the perimeter. At the front and rear ends of the top of the upper side plate 3012 of the housing, there is a horizontally distributed mounting ear 3013; Furthermore, the two mounting ears 3013 are symmetrically distributed front and back.

[0045] Furthermore, the mounting ear 3013 is provided with a threaded hole for connecting to the first upper cover plate end through hole 1030 on the first mounting bracket 1 or the second upper cover plate end through hole 2030 on the second mounting bracket 2 via the first fastener 4; Furthermore, a circular lens hole 30111 is provided on the bottom plate of the housing 3011; Lens hole 30111 is configured to correspond to the camera on camera module 308 inside housing 301, and is used to expose the camera on camera module 308 inside housing 301; Furthermore, a lens cap 304 is provided on the top surface of the lens hole 30111; It should be noted that the lens cap has high definition and high impact resistance to protect the camera; the lens cap 304 is attached to the top surface of the lens hole 30111 inside the housing with sealant (such as UV adhesive) to seal the lens hole and prevent water and dust.

[0046] Furthermore, a light hole 30112 is provided on the bottom plate 3011 of the housing; The light hole 30112 is provided corresponding to the light plate 306 inside the housing 301, and is used to expose the LED light 3061 at the bottom of the light plate 306; Furthermore, the top of the housing base plate 3011 is provided with two upwardly protruding stepped portions 30113; A threaded hole is provided on the stepped portion 30113; The two stepped portions 30113 are connected to the two ends of the lamp plate 306 inside the housing 301 by two second fasteners 309 (bolts).

[0047] Furthermore, the lamp panel 306 is provided with a lamp panel through hole 3060 at the position corresponding to the threaded holes of the two stepped portions 30113; After the second fastener 309 passes through the lamp plate through hole 3060 on the lamp plate 306, it is threadedly fixed to the threaded hole on the corresponding step portion 30113.

[0048] Two cylindrical, hollow isolation studs 307 are installed directly above the two lamp panel through holes 3060 of the lamp panel 306; A camera module 308 is mounted above the isolation stud 307; A lens 3080 is located at the bottom of one end of the camera module 308; The camera module 308 has two circular camera module through holes 3081 at positions corresponding to the threaded holes of the two stepped portions 30113; The second fastener 309 passes through the camera module through hole 3081 on the camera module 308, the center through hole of the isolation stud 307, and the lamp board through hole 3060 on the lamp board 306 in sequence from top to bottom, and is then threadedly fixed to the step threaded hole on the step portion 30113.

[0049] It should be noted that, in this invention, two second fasteners 309 are used, which pass through the camera module through hole 3081, the isolation stud 307, and the circular through hole (lamp plate through hole 3060) on the camera module 308 in sequence, and are connected to the threaded hole on the stepped portion 30113 inside the housing 301 to fix the lamp plate 306 and the camera module 308. It should be noted that the function of the isolation stud 307 is to provide mechanical support and fixation between the light board 306 and the camera module 308, and to maintain a precise distance to leave space for the components; It should be noted that the light panel 306 is equipped with two LEDs 3061 (light-emitting diodes), which are diagonally distributed and correspond to the light holes 30112 on the bottom plate 3011 of the housing. The two corners of the light panel 306 are provided with circular through holes. The LEDs are used to supplement the light for the camera module, ensuring that the light panel illuminates the notch on the switch machine indicator rod, so that the camera module can clearly and accurately capture the video and images (i.e., video) of the switch machine notch.

[0050] Furthermore, a frosted panel 305 is provided on the top surface of the housing base plate 3011; The frosted panel 305 is located directly below the lamp panel 306 inside the housing 301 and covers the light hole 30112 on the bottom plate 3011 of the housing; It should be noted that the frosted panel is used to avoid metallic reflection, making the LED light from the light panel uniform and soft, improving the lighting quality of the light panel, and helping the camera module to capture clear and accurate images; the frosted panel has adhesive backing and is pasted to the top surface of the housing base plate to seal the light holes, making it waterproof and dustproof.

[0051] In practice, the top cover 302 has horizontally symmetrically distributed circular through holes at both ends; A circular through-hole is provided in the center of the top cover, and a cable protection sleeve 303 is provided on the through-hole to protect the cable of the camera module 308 from damage when it passes through the top cover 302. It should be noted that the bottom center of the top cover has a downwardly protruding and surrounding side plate, which corresponds to the top opening of the housing 301. When the housing 301 and the top cover 302 are connected, a sealing treatment is performed. For example, a flat sealant is used to cover the protruding side plate at the bottom of the top cover, and the top cover side plate is inserted into the hollow interior of the housing 301 so that the lower surface of the top cover is flush with the upper surface of the housing 301. After the sealant cures, it can effectively fill the gap between the housing 301 and the top cover, thereby achieving good waterproof and dustproof functions.

[0052] In practice, the camera module 308 in camera assembly 3 is connected to the existing image acquisition equipment (such as the acquisition unit) inside the switch machine.

[0053] It should be noted that the camera module 308 has its own cable, which has data signal transmission and power supply functions. The cable passes through the top cover cable sleeve 303 and the mounting bracket and connects to the image data acquisition end of the original image acquisition equipment (such as the acquisition sub-unit) inside the switch machine. The acquisition sub-unit uploads the acquired image and video data to the indoor monitoring host (which is the original indoor monitoring host of the switch machine) located in a control room outside the switch machine, thereby realizing remote signal transmission. This enables remote, real-time, and automated intelligent monitoring of the switch machine gap status.

[0054] It should be noted that the in-machine image acquisition equipment is a mature and widely used technology. For example, the JZCD·ZC type acquisition unit produced by Tianjin Railway Signal Co., Ltd. can be used to receive various data such as image signals, video signals, and sensor analog signals and perform analysis and processing. The acquisition unit will then upload the processed data to the indoor monitoring host.

[0055] Based on the gap image acquisition device provided by the present invention, the present invention also provides a switch machine, which includes the gap image acquisition device as described above.

[0056] In specific implementation, the switch machine includes a bottom shell 7; The bottom shell 7 is a hollow shell with an open top; Inside the bottom shell 7, there are two switch machine indicator rods 6 that are horizontally distributed and arranged side by side; The top of the bottom shell 7 is sealed to the bottom of the switch machine cover 8; The two camera components 3 in the gap image acquisition device are used to acquire video images of the gaps on the two switch indicator rods 6. Specifically, they acquire an image of the gap between the edge of the gap at the top left end of one switch indicator rod 6 and the edge of the inspection post, and an image of the gap between the edge of the gap at the top right end of the other switch indicator rod 6 and the edge of the inspection post.

[0057] It should be noted that the various component structures installed inside and outside the bottom shell 7 are conventional supporting structures in existing mature switch machines, and will not be described in detail here.

[0058] In terms of specific implementation, it should be noted that the switch machine of the present invention is basically the same as the ZD6 type switch machine produced by Tianjin Railway Signal Co., Ltd. The main difference is that two mounting brackets that are specially designed to connect with the switch machine contact seat are designed, and the camera component 3 is newly designed.

[0059] In practice, the bottom rear side of the switch machine cover 8 is hinged (i.e., rotatably connected) to the top rear side of the switch machine bottom shell 7.

[0060] Compared with existing technologies, by applying this invention, it is possible to monitor gaps inside the switch machine, which helps to promptly detect and report the following problems: 1. Switch position status: The status of the gap directly reflects the position of the switch point rail. By monitoring the status of the gap, staff can promptly detect problems such as insufficient sealing strength, effectively preventing accidents such as train derailment.

[0061] 2. Avoiding turnout indication failure: If the gap exceeds the limit, the switch machine indication circuit will not be able to conduct normally, causing a turnout indication failure, which directly affects train operation safety. The device of this invention can transmit image and video signals to the indoor monitoring host originally matched with the switch machine, which is conducive to further real-time monitoring of the gap. When the gap exceeds the limit, the monitoring host will issue an alarm in time to remind maintenance personnel to carry out maintenance and avoid affecting train operation.

[0062] 3. Operational efficiency and safety: It allows maintenance personnel to view the status of gaps in real time, improving the efficiency of maintenance personnel in maintaining switch machines.

[0063] 4. By monitoring the status of gaps inside the switch machine, maintenance personnel can better assist in monitoring the status of the turnout and the movement status of the switch machine, which helps to predict and handle faults in advance and reduce the occurrence of faults.

[0064] Compared with the prior art, the notch image acquisition device and switch machine provided by the present invention have the following beneficial effects: 1. This invention is a gap image acquisition device applied in ZD6 type switch machine. By using an image acquisition component (i.e. camera component) installed on the switch machine contact seat 5, it can acquire image and video data of the gap status in the switch machine, thereby reflecting the tightness of the turnout switch rail and realizing remote online monitoring of the turnout switching equipment. 2. In this invention, two independent camera modules 3 are used to directly capture images of the notches on the left and right indicator poles of the switch machine; the two camera modules 308 do not interfere with each other, are easy to install, and have good maintainability; 3. In this invention, the camera component 3 is installed below the switch machine contact seat 5, not directly above the switch machine contact seat, so as not to obstruct the view of the gap inside the switch machine, not to affect manual inspection of the gap, and to facilitate daily inspection and maintenance by the staff. It should be noted that the lens of the camera assembly 3 is aimed at the notch at a specific tilt angle. Combined with the supplementary lighting of the light panel 306 and the frosted panel 305, reflections are effectively avoided, and a clear image of the notch can be obtained.

[0065] 4. In this invention, a sealed design is adopted. On the one hand, a sealing adhesive is applied between the housing 301 and the top cover to prevent water and dust from entering the camera assembly 3 from the top surface of the housing 301. On the other hand, a lens cover 304 and a frosted panel 305 are attached to the bottom surface of the housing 301 to completely seal the light hole and lens hole on the bottom surface of the housing 301, preventing water and dust from entering the camera assembly 3 from the light hole and lens hole on the bottom surface of the housing 301, thereby achieving good waterproof and dustproof functions. 5. The present invention is installed inside the switch machine, making full use of the original mounting holes on the switch machine contact seat, without the need to open additional mounting holes on the switch machine, and does not affect the protection level of the switch machine. 6. In this invention, the camera module 308 is preferably an analog camera, which has higher data transmission reliability and real-time performance than a digital camera in outdoor environments, harsh weather, high temperature environments, and motor interference. For example, in specific implementation, the camera module 308 can be a camera of model JQ 1•CT•ZM-8 produced by Tianjin Railway Signal Co., Ltd.

[0066] 7. The present invention is easy to disassemble, which facilitates the daily maintenance and repair of the switch machine by the staff.

[0067] 8. The present invention utilizes the light panel 306 to enable the camera assembly 3 to capture clear gap images in the enclosed and dark environment of the switch machine.

[0068] In summary, the gap image acquisition device of the present invention is installed inside the switch machine, has a reliable and safe structure, is easy and quick to install and disassemble, does not obstruct manual inspection of the gap, and can reliably acquire images and videos of the switch machine gap. This facilitates remote and real-time online monitoring of the switch machine gap status, helps staff to predict and handle switch machine malfunctions in advance, reduces the occurrence of malfunctions, and provides convenient conditions for on-site personnel to maintain and repair the switch machine.

[0069] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
