Description

Technical Field

[0001] The invention belongs to the technical field of radiation measurement in physics, and specifically relates to a delivery device capable of loading a marker inside a vehicle and an operating vehicle. Background Art

[0002] After a nuclear leak accident, in order to facilitate control, it is necessary to detect the area affected by the nuclear leak and mark the contaminated area with a marker. The marker generally includes a marker lamp, a marker pole and a hemispherical base connected from top to bottom. In the past, marking contaminated areas was mostly done manually, that is, workers wore protective equipment to enter the accident site, detect suspicious areas and place markers at the boundaries of the contaminated areas; because protective equipment has an effective protection time indicator, when the protective equipment is used beyond the effective protection time, the workers may be exposed to different forms of hazards such as radioactive rays, dust, nuclear and biological aerosols and nuclear and biological liquids. Therefore, manual placement is not only less safe and labor-intensive, but also not suitable for long-term operations.

[0003] In order to improve safety and reduce the intensity of manual labor, it is generally necessary for staff to enter the accident scene in a vehicle equipped with a protection system and release markers through a release device installed in or hung outside the vehicle. Since the number of markers loaded in the release device is limited, when the markers loaded in the release device are used up, the staff is required to open the hatch of the release device in the vehicle or get off the vehicle to reload the markers. Opening the hatch in the vehicle may cause the vehicle's protection system to temporarily fail and allow external pollutants to enter the vehicle. Getting off the vehicle to reload may cause harm and contamination by pollutants and bring them back to the vehicle. Therefore, loading markers requires driving away from the contaminated area, but this will not only reduce the timeliness and accuracy of the detection, but also take a long time to mark the contaminated area and reduce efficiency. For example, Chinese patent 2020113308374 discloses a method for controlling and using a radiation marker, in which the delivery device is hung outside the vehicle. Although multiple markers can be delivered at one time, the delivery device is rectangular as a whole, and has the disadvantages of large mass, bulky size, and abrupt appearance. In addition, the device is hung outside the vehicle, which not only requires leaving the contaminated area to reload the marker, resulting in low operating efficiency, but also the delivery port of the device is not closed. When the vehicle wades through water, the equipment and the marker are at risk of malfunctioning due to immersion in water, and the reliability is poor. If the device is installed directly in the vehicle and the delivery port is connected to the outside of the vehicle, external contaminated gases and radiation can easily enter the vehicle through the delivery port and the loading port during loading, posing a threat to the safety of people in the vehicle.

Even in a polluted environment, the loading hatch 6 can be opened, and the rotary drive mechanism can be controlled to drive the loading body 3 to rotate horizontally, so that each loading slot 4 is opposite to the loading port 5 one by one, and the marker is placed in each loading slot 4 through the loading port 5. , complete the loading, and then close the loading hatch 6; when the operating vehicle drives to the position to be delivered, stop for delivery, first open the delivery hatch 10, at this time, the loading hatch 6 is used to keep the inside and outside environments of the vehicle sealed and radiation isolated, and control the rotary drive mechanism to drive the loading body 3 to rotate horizontally, so that any loading slot 4 with a marker inside is vertically opposite to the release port 7, and then open the release hatch 8, the upper marker loses support and falls to the ground through the release port 7 and the delivery port 9 in turn, completing the delivery action; close the release hatch 8 and the delivery hatch 10, and the operating vehicle drives to the next position to be delivered, and delivers again.

[0023] The delivery device capable of loading a marker in a vehicle according to the present invention can be hung outside the vehicle or installed inside the vehicle. It is only necessary to ensure that the loading port 5 is located or extends into the vehicle in a sealed manner, and the delivery port 9 faces downward and is connected to the outside of the vehicle. When loading the marker, the environment inside the vehicle is kept sealed and isolated from radiation by the delivery hatch 10. Even in a polluted environment, the loading hatch 6 can be opened for loading without leaving the polluted area. When delivering the marker, the environment inside the vehicle is kept sealed and isolated from radiation by the loading hatch 6. During the entire operation, the loading hatch 6 and the delivery hatch 10 are alternately opened.

[0024] See also Figure 1 The device for delivering a marker for loading in a vehicle according to the present invention also includes a controller (not shown in the figure) and an induction switch (only a bracket 11 for installing the induction switch is shown in the figure). The controller is electrically connected to the rotary drive mechanism, the release drive mechanism, the delivery drive mechanism and the induction switch respectively. An annular positioning plate 12 is connected to the lower end of the loading body 3. The positioning plate 12 is coaxial with the horizontal rotation of the loading body 3. A positioning rod 13 is formed on the inner side of the positioning plate 12 along the radial protrusion. There are multiple positioning rods 13 and they correspond to the circumferential positions of each loading slot 4 one by one. The induction switch is fixedly arranged below the positioning plate 12. The positioning plate 12 can rotate horizontally with the loading body 3. Make each positioning rod 13 vertically face the induction switch one by one, and the induction switch is triggered when it is vertically facing the positioning rod 13. The controller controls the action of the rotary drive mechanism according to the signal fed back by the induction switch to ensure that the filling slot 4 and the release port 7 are vertically facing each other during delivery. During implementation, the horizontal angle between the axis of horizontal rotation of the loading port 5 and the loading body 3 and the release port 7 should correspond to the angle between the axes of horizontal rotation of any two loading slots 4 and the loading body 3, so that during loading, the controller controls the action of the rotary drive mechanism according to the signal fed back by the induction switch to make each loading slot 4 face the loading port 5 one by one. In this embodiment, the induction switch adopts a magnetic proximity switch.

[0025] In this way, through the cooperation of the induction switch and the positioning plate 12 that rotates horizontally with the filling body 3, each time the induction switch is triggered by the positioning rod 13 on the inner side of the positioning plate 12, a feedback signal will be given to the controller. During the process of the controller controlling the rotary drive mechanism to drive the filling body 3 to rotate, the controller can control the rotary drive mechanism to stop accordingly according to the signal feedback from the induction switch, so that each loading slot 4 is aligned with the release port 7 and the loading port 5 one by one, which is conducive to filling and realizing automatic delivery.

[0026] See also Figure 1 The loading chamber 1 and the loading body 3 are both cylindrical and have matching diameters. The marker in the loading groove 4 is blocked in the radial direction by the bottom of the loading groove 4 and the side wall of the loading chamber 1 so as to limit the radial movement of the marker. A circle of limiting grooves 14 is provided on the side wall of the loading chamber 1. The limiting grooves 14 extend vertically to the bottom of the loading chamber 1. The cross-section of the loading groove 4 is in the shape of an arc. The loading groove 4 is vertically divided into a guide section 15 and a limiting section 16. The limiting section 16 is located below the guide section 15 and has a depth greater than that of the guide section 15. A step surface 17 is formed between the guide section 15 and the limiting section 16. The limiting section 16 and the part of the limiting groove 14 radially opposite to each other are used to accommodate the base of the marker in the corresponding loading groove 4. The vertical dimensions of the limiting section 16 and the limiting groove 14 are matched with the thickness of the base of the marker. The base of the marker is located in the limiting section 16 and is vertically blocked by the step surface 17 and the upper side wall of the limiting groove 14 so as to limit the axial movement of the marker.

[0027] In this way, in the circumferential direction, the marker is restricted by the two side walls of the loading groove 4 so that the marker rotates with the loading body 3. In the radial direction, the marker is restricted by the bottom of the loading groove 4 and the side walls of the loading chamber 1 to avoid radial displacement of the marker during the rotation of the loading body 3. In the axial direction, it is restricted downward by the bottom surface of the loading chamber 1 and upward by the step surface 17 and the upper side wall of the limit groove 14 to avoid large axial movement of the marker due to vehicle vibration. Movement in three directions is restricted, so that the marker maintains a stable position and posture in the loading groove 4, thereby avoiding impact damage caused by the movement of the marker and rotation jamming of the loading body 3, which is beneficial to improving the stability of the delivery equipment and ensuring smooth delivery.

[0028] In this embodiment, the cabin shell includes a loading shell 18, a limiting shell 19 and a delivery shell 20 which are connected in sequence from top to bottom. The loading shell 18 and the limiting shell 19 are both cylindrical. The upper end of the loading shell 18 is closed by a loading top plate 41. The interior of the loading shell 18 and the limiting shell 19 is formed as the loading cabin 1. The limiting groove 14 is formed on the inner side of the limiting shell 19. The upper end of the limiting shell 19 is connected to the lower end of the loading shell 18. The lower end of the limiting shell 19 is closed by a loading bottom plate 42. The loading shell 18 is additionally provided with a door frame 46 for installing a loading cabin door 6, and a control box 47 for arranging electrical components such as a controller; the diameter of the loading shell 18 is smaller than the diameter of the limiting shell 19; the delivery shell 20 is rectangular and has an arc transition at one end; the interior of the delivery shell 20 is formed as the delivery cabin 2; the upper end of the delivery shell 20 is closed by a delivery top plate 43, and the lower end is closed by a delivery bottom plate 44; a partition plate 4540 is provided between the delivery top plate 43 and the delivery bottom plate 44 for vertically separating the delivery cabin 2; the release port 7 is provided on the loading bottom plate 42 and passes through the delivery top plate 43 and the partition plate 4540; the delivery port 9 is provided on the delivery bottom plate 44.

[0029] See also Figure 1 The release hatch 8 slides radially along the loading chamber 1 to open and close, and opens the release port 7 when sliding away from the loading body 3. The end of the release hatch 8 close to the loading body 3 is transitionally connected to the upper surface through a slope 21; in this way, when launching, the release hatch 8 slides radially outward, and the base of the marker is subjected to the friction force pushed outward by the release hatch 8. At this time, the marker light connected to the base through the marker rod will be subjected to a reaction force biased toward one side of the loading body 3. The release hatch 8 has a slope 21 at the end. When the slope 21 moves with the release hatch 8 to the edge of the base of the marker, the base will produce a certain inclination due to contact with the slope 21, so that the marker light is more biased toward the loading body 3, which plays a role in correcting the posture of the marker before launching, which is beneficial to improve the fault tolerance rate and ensure that the marker passes through the release port 7 smoothly; in addition, the depth of the guide section 15 decreases from top to bottom, so that the position of the marker can be adjusted by cooperating with the marker light during launching, thereby guiding the marker to pass through the release port 7 smoothly.

[0030] See also Figure 1The rotary drive mechanism is a worm gear electric rotary table (only the driving motor 22 of the worm gear electric rotary table is shown in the figure), and a clearance hole 23 is opened in the middle of the lower end of the loading body 3 on the bottom surface of the loading cabin 1. In this embodiment, the clearance hole 23 is opened on the loading bottom plate 42 and penetrates the delivery top plate 43. The output end of the worm gear electric rotary table is connected to the lower end of the loading body 3 through the clearance hole 23; the release drive mechanism is an electric push rod 24, which is arranged along the sliding direction of the release cabin door 8, and the telescopic end of the electric push rod 24 is connected to the release cabin The door 8 is connected; in the present embodiment, a worm gear electric rotary table of model Y200RA200 is adopted, and the electric push rod 24 is laterally spaced apart from the worm gear electric rotary table so as to reduce the height of the delivery device; in this way, the turbine worm mechanism in the worm gear electric rotary table has a deceleration effect, which can not only improve the load capacity of the worm gear electric rotary table, but also has a stop self-locking function, which is conducive to driving the loading body 3 to rotate and making each loading slot 4 face the release port 7 one by one, and avoiding accidental rotation of the loading body 3 during delivery.

[0031] See also Figure 1 The delivery drive mechanism includes two parallel and oppositely arranged guide plates 25, the guide plates 25 are provided with a sliding guide groove 26 extending laterally, a first slider 27 is slidably connected in the sliding guide groove 26, a motor 28 is provided between the two guide plates 25, and the housing of the motor 28 is respectively connected to the first sliders 27 on both sides through a connecting frame 29; a rack 30 with a tooth surface facing upward is provided in parallel on the outer side of the guide plate 25, a transmission rod 31 is vertically provided between the two guide plates 25, the motor 28 is connected to the transmission rod 31 through a transmission box 32, the end of the transmission rod 31 passes through the sliding guide groove 26 on the corresponding side and is connected to the gear 33, the gear 33 is meshed with the rack 30 on the corresponding side, the gear 33 and the first slider 27 on the same side are arranged at intervals along the sliding guide groove 26, the delivery port 9 is located between the two guide plates 25, and the delivery hatch 10 is horizontally arranged between the bottom surface of the delivery cabin 2 and the transmission rod 31 and connected to the outer shell of the transmission box 32, so that the motor 28 drives the delivery hatch 10 to move horizontally to achieve opening and closing.

[0032] In this way, since the first slider 27 in the sliding guide groove 26 can slide, the gear 33 meshing with the rack 30 can roll along the rack 30, so the whole formed by the transmission box 32 and the gears 33 on both sides and the motor 28 and the first sliders 27 on both sides can be regarded as a moving cart. The motor 28 drives the transmission rod 31 to rotate through the transmission box 32, and the gear 33 at the end of the transmission rod 31 rotates accordingly and rolls along the rack 30, thereby driving the moving cart to move horizontally, and the delivery hatch 10 connected to the bottom of the transmission box 32 can move to the delivery port 9 to block the delivery port 9.

[0033] See also Figure 1A second slider 34 is also slidably connected in the sliding guide groove 26. In the horizontal direction, one end of the sliding guide groove 26 is bent downward and extended to form a clamping guide groove 35. The transmission rod 31 is located between the first slider 27 and the second slider 34, and the second slider 34 is close to the clamping guide groove 35.

The connecting block 38 is rotatably connected, and the delivery hatch 10 is indirectly connected to the outer shell of the transmission box 32 through the connecting rod 37, the connecting block 38 and the transmission rod 31; the second slider 34 reaches the sliding guide groove 26, and the corresponding delivery hatch 10 moves horizontally to above the delivery port 9, and the second slider 34 moves downward along the sliding guide groove 26, and the corresponding delivery hatch 10 moves vertically to press and close the delivery port 9; during implementation, when the second slider 34 is located in the sliding guide groove 26, the upper surface of the delivery hatch 10 should be abutted against the transmission box 32 to prevent the delivery hatch 10 from swinging during the sliding process along the sliding guide groove 26.

[0034] In this way, when the motor 28 drives the moving trolley to move along the sliding guide groove 26, and the second slider 34 slides in the sliding guide groove 26, the delivery hatch 10 moves horizontally close to the delivery port 9. Since the connecting rod 37 and the transmission rod 31 are respectively rotatably connected to the connecting block 38, when the second slider 34 reaches the clamping guide groove 35, the delivery hatch 10 is correspondingly located above the delivery port 9. At this time, the connecting block 38 acts as a swing arm, so that the second slider 34 can swing downward around the transmission rod 31 and enter the clamping guide groove 35 to move downward, and the delivery hatch 10 connected to the connecting rod 37 moves downward, and finally the delivery hatch 10 abuts against and covers the delivery port 9 and maintains a certain pressure. Compared with only horizontal movement and closing, further pressing down after horizontal movement is beneficial to improving the reliability of the sealing fit between the delivery hatch 10 and the delivery port 9; in addition, in order to reduce the friction of sliding, the first slider 27 and the second slider 34 both use circular rollers and are rotatably connected to the connecting frame 29 and the connecting rod 37, respectively.

[0035] See also Figure 1, a vertical through hole 39 is provided on the filling body 3, the axis of the through hole 39 corresponds to the axis of the horizontal rotation of the filling body 3, and the induction switch and the positioning rod 13 are both within the range of the vertical projection of the through hole 39; in this way, by setting the through hole 39, not only the weight of the filling body 3 can be reduced, but also the positional relationship between the induction switch and the positioning rod 13 when the filling body 3 rotates can be observed through the through hole 39, so as to facilitate the debugging of the controller controlling the rotary drive mechanism; a partition 40 is connected between adjacent loading slots 4 on the side of the filling body 3, and the end of the partition 40 away from the filling body 3 is close to the side wall of the loading chamber 1, so as to cooperate with the loading slot 4 to limit the circumferential movement of the marker; in this way, the partition 40 replaces the loading slot 4 to limit the circumferential movement of the marker, which is conducive to reducing the volume and weight of the filling body 3, so that the structure of the delivery device is more compact and the weight is lighter.

[0036] The delivery device for loading markers in a vehicle of the present invention is used to be installed on a working vehicle for delivering markers. During installation, the loading port 5 should be located in the vehicle, and the delivery port 9 should face downward and be connected to the outside of the vehicle. During implementation, the delivery device can be vertically installed on the side of the vehicle body of the working vehicle and the loading port 5 can be sealed and extended into the vehicle. Alternatively, a hole corresponding to the delivery port 9 can be reserved on the floor of the working vehicle, and the delivery device can be vertically installed on the floor of the working vehicle so that the delivery port 9 is opposite to the hole, and a seal can be used to separate the delivery port 9 and the hole from the space inside the vehicle.

[0037] The delivery device of the present invention is installed on the working vehicle for delivering the marker, which can ensure the establishment of the integrated support system in the vehicle, and is used for automatically delivering the contaminated marker when demarcating the boundary of the contaminated area at the scene of nuclear, biological and chemical leakage, accidents, etc. It can effectively replace manual marking of the contaminated position, and also prevent personnel from contacting the contaminated substances, which can effectively improve the safety of on-site personnel, provide warnings and reminders for the boundary of the contaminated area, and prevent the rear personnel from mistakenly entering the contaminated area, thereby avoiding damage to personnel and equipment. It can automatically deliver the marker by receiving instructions under the condition of isolation state, which is mainly used to mark the contaminated areas and boundaries that are contaminated by nuclear, biological and chemical pollution, and provide intuitive and eye-catching warnings for self-protection, avoiding contamination, and eliminating hazards.

[0038] In actual application, personnel are located inside the carrier platform equipped with the device. They first open the loading hatch 6 to complete the loading of the marker, and then control the delivery device to perform the delivery operation through the upper computer electrically connected to the control box 47. Information such as the quantity of delivery can be displayed in real time through the upper computer.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Those skilled in the art should understand that those modifications or equivalent substitutions of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution should be included in the scope of the claims of the present invention.
