Description

Technical Field

[0001] This invention belongs to the field of tunnel illumination detection technology, specifically relating to a tunnel illumination detection device and method. Background Technology

[0002] Good tunnel lighting has a significant impact on driving safety and comfort. In the design of tunnel lighting, it is necessary to consider the difference in brightness between the inside and outside of the tunnel under various weather conditions, as well as the lighting of the entrance section, transition section and exit section, to solve the problem of dark adaptation during the day and the problem of black and white holes at the tunnel entrance at night. After the tunnel lighting system is completed, the illuminance of the tunnel needs to be measured.

[0003] According to the standard "Detailed Specifications for Lighting Design of Highway Tunnels," a tunnel is divided into four sections: entrance section, transition section, intermediate section, and exit section. Current technology typically uses multiple lux meters to measure the illuminance of each section, employing a rectangular grid method. Longitudinally, each section is divided into multiple horizontal lines based on the tunnel's length, and laterally, multiple longitudinal lines are drawn based on the tunnel's cross-section. Lux meters are installed at each intersection to measure the illuminance at various points within the tunnel. However, as tunnel length increases, this method becomes inefficient for illuminance measurement. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a device and method for detecting tunnel illuminance, which can improve the detection efficiency of tunnel illuminance.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention discloses a tunnel illumination detection device, comprising a lateral shrinking mobile vehicle and a lateral shrinking tailstock mounted on the lateral shrinking mobile vehicle. Multiple sets of detection rods are installed on the lateral shrinking tailstock, with the rods spaced laterally across the device. One end of each detection rod is connected to the lateral shrinking tailstock, and the other end extends longitudinally away from the tailstock. Multiple illumination detectors are evenly spaced on each detection rod. The lateral shrinking tailstock includes an inner support tail tube mounted on the lateral shrinking mobile vehicle and an outer support tail tube slidably sleeved outside the inner support tail tube. The inner and outer support tail tubes have openings for the detection rods to make way. Multiple sets of sliding columns are arranged inside the inner and outer support tail tubes. The sliding column at the end away from the outer support tail tube is fixedly installed inside the inner support tail tube. Each sliding column is connected to a corresponding detection rod, and an elastic support device connects adjacent sliding columns. A compression column is threadedly connected to the inner side of the outer support tail tube, located at the end away from the inner support tail tube.

[0007] Furthermore, a central guide post is fixed at the center of the compression column, and a guide hole that mates with the central guide post is opened at the center of the sliding column.

[0008] Furthermore, the detection rod includes a rigid tube and a flexible telescopic tube. Multiple sets of rigid tubes and flexible telescopic tubes are arranged alternately along the axial direction of the detection rod. The rigid tube closest to the lateral retraction tailstock is fixedly connected to its corresponding sliding column. The rigid tube is slidably disposed in the opening groove. Each set of detection rods consists of rigid tubes located in the same lateral direction. The rigid tubes in the same set are connected by a lateral retraction rod, which is connected to the vertical displacement control component.

[0009] Furthermore, the vertical displacement control component includes a vertical track, a vertical telescopic device installed inside the vertical track, a lateral retraction rod that slides with the vertical track, and the output end of the vertical telescopic device that is connected to the lateral retraction rod.

[0010] Furthermore, the lower end of the vertical track is slidably mounted on the horizontal track installed on the transverse shrinkage moving vehicle, and a longitudinal shrinkage control component is installed between two adjacent rigid pipes.

[0011] Furthermore, the longitudinal shrinkage control assembly includes a longitudinal telescopic device fixed on a rigid tube, a limit rail installed on an adjacent rigid tube, and the output end of the longitudinal telescopic device is connected to a sliding sleeve, which is slidably installed in the limit rail along the vertical direction.

[0012] Furthermore, the lateral retraction rod includes an outer rod and an inner rod slidably mounted on one end of the outer rod. Corresponding grooves are provided on the inner rod and the outer rod. A sliding shaft corresponding to the sliding groove is installed on the detection rod. The sliding shaft is connected to the outer rod and to the inner rod by a locking member.

[0013] Furthermore, the lateral retractable mobile vehicle includes a left body, a right body, and rollers installed at the bottom of the left and right bodies. The left body has a limiting groove that slides with the right body, and the left and right bodies are connected by a locking component.

[0014] A method for detecting tunnel illuminance employs a tunnel illuminance detection device as described above. First, the width of the lateral retraction moving vehicle, the length of the lateral retraction tailstock, and the lateral retraction rod are adjusted according to the tunnel width to adapt to the tunnel width. This ensures that each detection rod corresponds to the position of the left side wall, left curb, left driving centerline, road centerline, right driving centerline, right curb, and right side wall. Then, the distance between two adjacent illuminance detectors is adjusted according to a preset distance. Next, the illuminance at the tunnel entrance section is detected. After the detection is completed, the lateral retraction moving vehicle is moved longitudinally along the tunnel, and the illuminance at the tunnel transition section, middle section, and exit section is detected in the same manner.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention discloses a tunnel illuminance detection device, which installs multiple illuminance detectors on multiple detection rods, thereby enabling the detection of tunnel illuminance within a certain range. By moving the lateral retraction mobile vehicle to other positions, the illuminance detection requirements of the entire tunnel can be met, thus simplifying the structure while improving the efficiency of illuminance detection.

[0017] In the device disclosed in this invention, both the lateral retractable moving vehicle and the lateral retractable tailstock can retract laterally, allowing the device to adapt to the inspection requirements of tunnels of different widths. After retraction, both the lateral retractable moving vehicle and the lateral retractable tailstock can shorten their original length, ensuring that they do not interfere with the tunnel wall or affect the normal operation of the device during relocation.

[0018] When adjusting the lateral position of the detection rod, the stability of the adjustment is ensured by the guiding action of the lateral retraction tailstock. An elastic support device connects to the sliding column of the detection rod, ensuring the consistency of the elastic force of the support device. This allows the detection rods to maintain the same interval at all times, facilitating simultaneous and uniform adjustment of their positions for a more even and faster result.

[0019] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0030] like Figures 1-8 As shown, this invention discloses a tunnel illumination detection device, comprising a lateral retractable mobile vehicle 1 and a lateral retractable tailstock 2 mounted on the lateral retractable mobile vehicle 1. With the tunnel's extension direction as the longitudinal direction, the lateral retractable tailstock 2 extends laterally, with the moving front end of the lateral retractable mobile vehicle 1 as the head, and the lateral retractable tailstock 2 located at the rear of the entire device. Both the lateral retractable mobile vehicle 1 and the lateral retractable tailstock 2 can shorten their original length after retraction, and when the device is moved again, it will not interfere with the tunnel wall or affect the normal use of the device.

[0031] In some other embodiments, the lateral retractable mobile vehicle 1 includes two partially overlapping support plates, including a fixed support plate and a movable support plate. When retracting, the fixed support plate can be fixed, and the movable support plate can move relative to each other in the lateral direction. By locking the plate with locking member 25, the lateral retractable mobile vehicle 1 can retract in the lateral direction.

[0032] In this embodiment of the invention, seven sets of detection rods 3 are installed on the transverse retractable tailstock 2, corresponding to the positions of the left side wall, left curb, left driving center line, road center line, right driving center line, right curb, and right side wall of the tunnel, respectively. Multiple sets of illuminance detectors 4 are evenly spaced on the detection rods 3; thus, illuminance can be detected at the aforementioned positions. This invention employs a rectangular grid method. Longitudinally, each segment is 5-10 meters long according to the tunnel length, and transversely, the tunnel cross-section is evenly divided into left curb, left driving center line, road center line, right driving center line, and right curb. A reference value is measured at a height of 2 meters on both the left and right side walls.

[0033] Seven sets of detection rods 3 are distributed at horizontal intervals in the equipment, and can be preset according to their actual corresponding positions. One end of the detection rod 3 is connected to the horizontal shrink tailstock 2, and the other end of the detection rod 3 extends along the longitudinal direction of the equipment away from the horizontal shrink tailstock 2; in some other embodiments, the seven sets of detection rods 3 are located at the same horizontal height for easy control and adjustment.

[0034] Specifically, the lateral retractable tailstock 2 disclosed in this invention includes an inner support tail pipe 5 installed on a lateral retractable moving vehicle 1 and an outer support tail pipe 6 slidably sleeved on the outside of the inner support tail pipe 5. The inner support tail pipe 5 extends laterally, and the inner diameter of the outer support tail pipe 6 is adapted to the outer diameter of the inner support tail pipe 5, thereby allowing the outer support tail pipe 6 to move along the axial direction of the inner support tail pipe 5. At the same time, the inner support tail pipe 5 and the outer support tail pipe 6 are always coaxial.

[0035] Furthermore, in this embodiment of the invention, the inner support tail tube 5 and the outer support tail tube 6 are provided with openings 7 for making way for the detection rod 3. Multiple sets of sliding columns 8 are provided on the inner side of the inner support tail tube 5 and the outer support tail tube 6. Some of the sliding columns 8 are fixedly installed in the inner support tail tube 5. The sliding columns 8 are connected to the detection rod 3 in a one-to-one correspondence. An elastic support device 9 is connected between two adjacent sliding columns 8. The elastic support device 9 uses springs with the same elastic coefficient. The two ends of the spring are fixedly connected to two adjacent sliding columns 8 respectively. A compression column 30 is threadedly connected to the inner side of the outer support tail tube 6. The compression column 30 is located at the end away from the inner support tail tube 5.

[0036] When controlling the compression column 30, rotating the compression column 30 causes it to shift towards the end where the inner support tail tube 5 is located. The compression column 30 compresses the sliding column 8, which, through the action of the elastic support device 9, acts on the other sliding columns 8, allowing them to move synchronously and facilitating adjustment. The elastic support devices 9 connect the sliding columns 8 connected to the detection rod 3, ensuring the consistency of the elastic force of the elastic support devices 9. This allows the detection rods 3 to maintain the same interval at all times, thus facilitating simultaneous and unified adjustment of the positions of the detection rods 3. Of course, the positions of two adjacent detection rods 3 can be set as needed by changing the length and elastic coefficient of the corresponding elastic support device 9, as those skilled in the art will understand.

[0037] In this embodiment, a central guide post 10 is fixed at the center of the compression post 30, and a guide hole 11 that mates with the central guide post 10 is opened at the center of the sliding post 8. The length of the central guide post 10 is longer than the length of the outer support tail tube 6, but is definitely less than the overall length of the transverse retractable tail seat 2. When the compression post 30 is moved, the central guide post 10 can move together. The central guide post 10 can guide the sliding post 8 inside the outer support tail tube 6, reducing the possibility of the sliding post 8 getting stuck during movement.

[0038] In this embodiment, the detection rod 3 includes a rigid tube 12 and a flexible telescopic tube 13. Four sets of rigid tubes 12 and three sets of flexible telescopic tubes 13 are arranged alternately along the axial direction of the detection rod 3. The number of rigid tubes 12 and flexible telescopic tubes 13 can be selected according to the actual number of illuminance detectors 4. By installing the illuminance detectors 4 on the rigid tubes 12, the stability during measurement can be guaranteed. The flexible telescopic tubes 13 are made of rubber corrugated pipes. The rigid tube 12 closest to the lateral retraction tailstock 2 is fixedly connected to its corresponding sliding column 8. The rigid tube 12 is slidably arranged in the opening groove 7. Each set of detection rods 3 with rigid tubes 12 located in the same lateral direction is considered as one group. The same group of rigid tubes 12 is connected by a lateral retraction rod 14, which is connected to the vertical displacement control component.

[0039] In some other embodiments, the detection rod 3 can also be set as a fully flexible telescopic bellows, so it can be telescopic along the entire axial direction. This embodiment adopts this method. By setting the rigid tube 12, it can be connected to the transverse contraction rod 14 or the illuminance detector 4, and the connection is more stable.

[0040] In this embodiment, the vertical displacement control component includes a vertical track 15, a vertical telescopic device 16 installed inside the vertical track 15, and a horizontal retraction rod 14 that slides with the vertical track 15. The output end of the vertical telescopic device 16 is connected to the horizontal retraction rod 14. The vertical telescopic device 16 uses a hydraulic cylinder, which can drive the horizontal retraction rod 14 to move up and down, thereby adjusting the detection height of the illuminance detector 4 at that position to adapt to the illuminance detection requirements of tunnels with different slopes. In this embodiment, the vertical track 15 has a vertical groove, which allows the end of the horizontal retraction rod 14 to slide into it. Both ends of the horizontal retraction rod 14 are equipped with corresponding vertical tracks 15, which improves the balance of the device's movement.

[0041] In this embodiment, the lower end of the vertical track 15 is slidably mounted on the horizontal track 17 installed on the transverse shrinkage moving vehicle 1, and a longitudinal shrinkage control component is installed between two adjacent rigid tubes 12. The distance between two adjacent rigid tubes 12 can be adjusted by the longitudinal shrinkage control component to meet the needs of different illumination detection positions.

[0042] In this embodiment, the longitudinal contraction control component includes a longitudinal telescopic device 18 fixed to a rigid tube 12. A limiting rail 20 is installed on an adjacent rigid tube 12, and the limiting rail 20 is fixedly installed on one side of the rigid tube 12. The output end of the longitudinal telescopic device 18 is connected to a sliding sleeve 19, which slides vertically within the limiting rail 20. Since the rigid tube 12 can move both longitudinally and vertically, this embodiment of the invention provides a sliding sleeve 19 that can slide vertically. The position of the sliding sleeve 19 can be adjusted longitudinally, and the sliding sleeve 19 will not interfere with the rigid tube 12 vertically. The vertical and longitudinal movements are independent of each other, facilitating control.

[0043] In some other embodiments, the longitudinal contraction control assembly may also employ a hydraulic cylinder, with each end of the cylinder connected to two adjacent sets of vertical rails 15. The extension and retraction of the detection rod 3 is controlled by controlling the movement of the vertical rails 15.

[0044] In this embodiment, the transverse retractable rod 14 includes an outer rod 21 and an inner rod 22 slidably mounted on one end of the outer rod 21. Corresponding grooves 23 are formed on the inner rod 22 and the outer rod 21. A sliding shaft 24 corresponding to the groove 23 is mounted on the detection rod 3. The sliding shaft 24 is connected to the outer rod 21 and to the inner rod 22 via a locking member 25. The grooves 23 on the inner rod 22 and the outer rod 21 correspond to each other, thus facilitating the passage of the sliding shaft 24. The locking member 25 can be a nut threadedly connected to the sliding shaft 24. By changing the relative position between the inner rod 22 and the outer rod 21, they can be fixed together by the locking member 25.

[0045] In this embodiment, the laterally retractable mobile vehicle 1 includes a left body 26, a right body 27, and rollers 28 installed at the bottom of the left body 26 and the right body 27. The left body 26 has a limiting groove 29 that slides with the right body 27. The left body 26 and the right body 27 are connected by a locking member 25. During retraction, the left body 26 is fixed, and the right body 27 is slid inwards, allowing the right body 27 to penetrate into the left body 26. After locking with the locking member 25, the vehicle body can be retracted. In this embodiment, both the left body 26 and the right body 27 include two parallel mounting plates and a support column 31 connecting the mounting plates. The two mounting plates on the left body 26 not only have limiting grooves 29, but also slots 32 for the support column 31 of the right body 27 to make way, thereby enabling rapid retraction of both.

[0046] A method for detecting tunnel illuminance employs a tunnel illuminance detection device as described above. First, the width of the lateral retraction moving vehicle 1, the length of the lateral retraction tailstock 2, and the lateral retraction rod 14 are adjusted according to the tunnel width, so that the three are adapted to the tunnel width. This ensures that each detection rod 3 corresponds to the position of the left side wall, left curb, left driving centerline, road centerline, right driving centerline, right curb, and right side wall, respectively. Then, the distance between two adjacent illuminance detectors 4 is adjusted according to a preset distance. Next, the illuminance at the tunnel entrance section is detected. After the detection is completed, the lateral retraction moving vehicle 1 is moved longitudinally along the tunnel, and the illuminance at the tunnel transition section, middle section, and exit section is detected in the same manner.

[0047] This invention also utilizes the rectangular grid method for a more objective evaluation, employing specific detection methods to provide more reliable data for different tunnels. Corresponding maintenance measures are implemented for the brightness of operating tunnels. In the tunnel mileage section, "K1" represents the 1 km mark, "K2" represents the 2 km mark, and "K3" represents the 3 km mark; those skilled in the art should understand this. "K1+200" represents the position 1 km 200 m from the starting point, and so on. Table 1 shows the illuminance monitoring data for this embodiment, and Table 2 shows the road surface brightness calculation results.
