Description

Technical Field

[0002] When the shore container crane (abbreviated as "quay crane" or "bridge crane") performs container loading and unloading operations at the port, the roadside container truck positioning system (Container-vehicle Position System, CPS) or the vehicle-top lidar system is usually used to locate and guide the vehicle. Compared with the vehicle-top lidar system, CPS is usually installed in a fixed position on the shore crane, with a longer service life and detection accuracy, becoming the mainstream method of high-precision positioning of container trucks. Port container operations require CPS to provide 7×24 hours of full-time service, but in addition to container operation scenes, ports also have bulk cargo operation scenes such as coal and ore, which makes the operating environment dusty. The dust will adhere to the radar surface of the CPS, which is easy to form stains after a long time, affecting the radar's recognition effect and reducing the radar's service capabilities. In order to ensure the smooth progress of container operations, the CPS radar needs to be cleaned regularly.

Figure 3 for Figure 2 main view.

[0053] In the embodiments provided in this application, Figure 1 and Figure 2 As shown, the radar cleaning device is used to clean the radar 1, which is the radar of the container truck positioning system on the quay bridge 2. One end of the radar 1 is arranged on the base 3, and the base 3 is connected to the quay bridge 2. The base 3 is specifically arranged on the connecting frame 23 of the quay bridge 2; the radar cleaning device includes a cleaning medium storage device 4 and a cleaning component 6; the cleaning medium storage device 4 is arranged on the quay bridge 2, and the cleaning component 6 is arranged on the base 3; please refer to Figure 2 and Figure 3 The cleaning component 6 includes at least one cleaning pipe 61 and at least one nozzle 62. The cleaning medium storage device 4 is connected to the cleaning pipe 61. The at least one cleaning pipe 61 and the at least one nozzle 62 correspond to each other and are connected. The nozzle 62 is used to spray the cleaning medium onto the surface a to be cleaned of the radar 1.

[0054] When in use, the cleaning medium is stored in the cleaning medium storage device 4, and the cleaning medium can enter the nozzle 62 through the cleaning pipe 61, and the nozzle 62 automatically sprays the cleaning medium onto the surface a to be cleaned of the radar 1 to clean the radar 1. There is no need for an operator to climb onto the quay crane 2 to hold a cleaning device for cleaning operations, which can reduce the difficulty of cleaning the radar 1 in the roadside container truck positioning system on the quay crane 2, improve the safety of the cleaning operation and the cleaning efficiency, so as to effectively reduce the manpower cost and time cost of the operation and maintenance of the container truck positioning system, and ensure the normal operation of the container truck positioning system.

[0055] Please refer to Figure 4 , Figure 4 This is a structural schematic diagram of the radar cleaning device of the embodiment provided in the present application being installed on the connecting frame at a second viewing angle.

[0056] In the embodiment provided in the present application, the cleaning component 6 also includes at least one mounting bracket 63; the mounting bracket 63 is arranged on the base 3, and the mounting bracket 63 is provided with at least one mounting hole b; the nozzle 62 and the mounting hole b correspond one to one, and the nozzle 62 is passed through the corresponding mounting hole b.

[0057] In this way, the mounting frame 63 can provide stable support for the nozzle 62, so that the process of the nozzle 62 spraying the cleaning liquid is more stable, thereby improving the stability of the cleaning operation.

[0058] After the nozzle 62 passes through the mounting hole b of the mounting frame 63 , the nozzle 62 and the mounting frame 63 may be fixed by welding or by colloid bonding, without any specific limitation.

[0059] In fact, the relatively fixed installation of the nozzle 62 can also be achieved by passing the cleaning pipe 61 through the installation hole b, and there is no limitation in the specific setting.

[0060] It is not difficult to understand that the type of radar 1 used for positioning in the container truck positioning system is not limited, for example, it can be a millimeter wave radar or a laser radar; the shape of the radar 1 is also not limited, for example, it can be spherical or cylindrical. In actual setting, the structure of the mounting frame 63 is also not limited, and can be set according to the specific structure of the radar 1.

[0061] As an optional solution, the radar 1 can be a cylindrical laser radar, the cylindrical surface of the radar 1 is its laser emission surface, that is, the surface to be cleaned a, and the radar 1 has an axis d. Among them, the laser radar is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of the target. As an optical sensing component, it has high requirements for the cleanliness of the laser emission surface, so the surface of the laser radar needs to be cleaned. Please refer to Figure 4The mounting frame 63 may include a first mounting plate 631 and a second mounting plate 632; the base 3 has a mounting surface c at the other end facing away from the radar 1, corresponding to Figure 4 In the figure, the other end of the radar 1 is the front end, the mounting surface c is the rear end surface of the base 3, the first mounting plate 631 is arranged on the mounting surface c, the first mounting plate 631 is perpendicular to the axis d, the second mounting plate 632 is connected to the end of the first mounting plate 631 away from the axis d, and there is a first angle between the second mounting plate 632 and the first mounting plate 631, the first angle is toward the radar 1, the first angle is an obtuse angle, and the second mounting plate 632 has the above-mentioned mounting hole b.

[0062] In this way, the first mounting plate 631 can fix the second mounting plate 632 to the base 3, and the second mounting plate 632 provides a mounting position for the nozzle 62, which is used to support the nozzle 62, and can achieve a stable installation of the nozzle 62. It is not difficult to understand that the first mounting plate 631 is located at the rear side of the base 3, and the second mounting plate 632 and the first mounting plate 631 are set at an obtuse angle, so that the second mounting plate 632 can extend forward and to the side away from the axis d, which can make the nozzle 62 face the surface a to be cleaned after installation to ensure the cleaning effect, and can make the second mounting plate 632 and the nozzle 62 as far away from the surface a to be cleaned as possible, so as not to block the sensing range of the laser radar, and relatively ensure the smooth operation of the laser radar.

[0063] When cleaning radars 1 of other shapes, the positions of the mounting bracket 63 and the nozzle 62 can be adaptively set.

[0064] Please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic structural diagram of the radar cleaning device of the embodiment provided in the present application being installed on the connecting frame at a third viewing angle. Figure 6 This is a schematic diagram of the structure of the radar cleaning device of the embodiment provided in this application installed on the connecting frame at the fourth viewing angle. Figure 5 The connecting bolts 9 are not shown. Figure 5 and Figure 6 Only a portion of the connecting frame 23 is shown.

[0065] In actual configuration, the second mounting plate 632 may be a whole plate or a structure composed of multiple plates, and there is no specific limitation.

[0066] In the embodiments provided in this application, please combine Figure 5 and Figure 6It is understood that the second mounting plate 632 includes a connecting plate 6321 and two mounting sub-plates 6322; the connecting plate 6321 is connected to the first mounting plate 631, and the two mounting sub-plates 6322 are respectively arranged on both sides of the connecting plate 6321, and there is a second angle between the two mounting sub-plates 6322 and the connecting plate 6321, and the second angle is toward the radar 1. The two second angles are both obtuse angles, and the two mounting sub-plates 6322 are both provided with mounting holes b.

[0067] When in use, the mounting sub-plate 6322 can be used to support the nozzle 62, and the connecting plate 6321 and the first mounting plate 631 can be used to fix the nozzle 62 on the base 3, so that the installation of the nozzle 62 can be more stable, and the angles between the two mounting sub-plates 6322 and the connecting plate 6321 are both obtuse angles, so that the two mounting sub-plates 6322 are arranged on both sides of the connecting plate 6321, which can expand the area covered by the nozzles 62 set on the two mounting sub-plates 6322 and the sprayed cleaning medium to improve the cleaning effect, and is also beneficial to reduce the number of nozzles 62 to reduce production costs.

[0068] In addition, please combine Figure 5 It is understood that the two mounting sub-plates 6322 and the connecting plate 6321 can be enclosed into an arc-like structure, which can be matched with the cylindrical shape of the radar 1, which is beneficial to ensure the relative position between the nozzle 62 and the surface a to be cleaned, so that the nozzle 62 can cooperate with the cleaning medium sprayed to more accurately cover the part of the surface a to be cleaned.

[0069] It can be understood that the two second angles can be unequal or equal, and there is no specific limitation. In the embodiment provided in the present application, the two second angles can be equal, so that the two mounting sub-plates 6322 can be symmetrically arranged about the cross-center section of the connecting plate 6321, so that the two nozzles 62 connected by the two mounting sub-plates 6322 are symmetrically arranged, so that the cleaning medium sprayed by the two nozzles 62 is more evenly distributed, which is conducive to improving the cleaning effect.

[0070] It is worth noting that the first mounting plate 631 and the second mounting plate 632 can be formed separately or integrally, and there is no specific limitation. As an optional solution, the first mounting plate 631 and the second mounting plate 632 can be integrally formed, and a plate can be divided into a first part and a second part, and the first part is used as the first mounting plate 631. After the second part is bent toward one side of the first part, a part is cut inward from both ends of the bending point between the first part and the second part, and then the cut two sides of the second part are bent toward the middle, thereby forming a connecting plate 6321 in the middle of the second part, and two mounting sub-plates 6322 are formed on both sides. In this way, the same plate is cleverly used to form the mounting frame 63 by bending, and the molding process is simple, the processing cost is low, and the production raw materials can be saved, and the strength of the mounting frame 63 can also be improved.

[0071] In actual setting, the connection method between the first mounting plate 631 and the base 3 is not limited, for example, welding, clamping, or Figure 6 As shown, it is connected to the base 3 using connecting bolts 9. Figure 6 In the embodiment, each first mounting plate 631 can be connected to the base 3 by two connecting bolts 9, so that the installation of the first mounting plate 631 is more stable and convenient to disassemble for inspection and replacement.

[0072] In actual settings, the number and arrangement of the mounting frames 63 are set according to the number and arrangement requirements of the nozzles 62, and the number and arrangement of the nozzles 62 are set according to the cleaning requirements, without any specific restrictions.

[0073] Please refer to Figures 7 to 10 , Figure 7 for Figure 5 The front view of the radar cleaning device shown, Figure 8 for Figure 5 Left side view of the radar cleaning device shown, Fig. 9 for Figure 5 A top view of the radar cleaning device shown, Fig.10 for Figure 5 Rear view of the radar cleaning unit shown.

[0074] Please combine Figure 1 , Fig. 9 and Fig.10 It is understood that the radar cleaning device also includes a delivery pipe 7, and the cleaning component 6 also includes a connector 64; there are more than two cleaning pipes 61, and the connector 64 includes a main joint 641 and more than two branch joints 642 that are interconnected. The main joint 641 is connected to the cleaning medium storage device 4 through the delivery pipe 7, and the branch joint 642 and the cleaning pipe 61 correspond to each other and are connected.

[0075] With such arrangement, the connector 64 integrates each cleaning pipe 61, and the mounting frame 63 integrates each nozzle 62, so as to realize the integration of the entire cleaning assembly 6, and can further ensure the stability of the installation of the nozzle 62, so as to better ensure the relative position relationship between the nozzle 62 and the surface a to be cleaned of the radar 1, and relatively ensure the stability of the cleaning process and the cleaning effect, and at the same time, make the structure of the cleaning assembly 6 more compact and convenient for assembly.

[0076] Specifically, Fig. 9As shown, the connecting piece 64 can be arranged on the rear side of the base 3, and each cleaning pipe 61 can first extend forward and in a direction away from the axis d. After extending to the outside of the mounting plate 6322, it can extend forward and in a direction close to the axis d, so that the connected nozzle 62 passes through the mounting hole b from the outside to the inside of the mounting plate 6322. The entire cleaning pipe 61 is arc-shaped, and the first mounting plate 631 is located in a groove formed by the bending of the cleaning pipe 61. In this way, through clever design, the structure of the entire cleaning assembly 6 is more compact, and the structural stability and rigidity are higher.

[0077] In the specific setting, the connection method between the delivery pipe 7 and the connecting piece 64 is not limited, for example, it can be a welding method, a threaded screwing method, or a quick plug method. Figure 1 and Figure 8 It is understood that in the embodiment of the present application, the delivery pipe 7 and the connecting piece 64 can be connected by a quick-insert method, which can realize rapid installation and disassembly between the cleaning component 6 and the delivery pipe 7, is easy to operate, and makes the connection between the delivery pipe 7 and the cleaning component 6 more stable and reliable, which is conducive to improving the stability of the cleaning operation.

[0078] When specifically configured, the material and manufacturing method of the nozzle 62 and the connector 64 are not limited. In the embodiment of the present application, the nozzle 62 and the connector 64 can be made by 3D printing, and common 3D printing materials such as plastic can be used. In this way, the manufacturing cost can be reduced, and the structure of the cleaning component 6 is simpler, and the installation is more convenient. The weight of the cleaning component 6 can also be reduced, which is conducive to the lightweight of the entire radar cleaning device.

[0079] During specific configuration, the materials of the cleaning pipe 61 and the delivery pipe 7 are not limited. For example, PPR material can be used to further reduce the cost and lighten the weight of the radar cleaning device.

[0080] Please combine Figure 7 and Figure 8 It is understood that the radar 1 can be set horizontally, that is, the axis d can be set horizontally, the part of the surface a to be cleaned located below the axis d is the lower surface a1, and the part located above the axis d is the upper surface a2, and the cleaning medium sprayed by each nozzle 62 at least covers the lower surface a1.

[0081] It is not difficult to understand that the radar 1 is horizontally arranged, and its cylindrical surface is the laser emitting surface. The container truck below is positioned by emitting laser. The lower surface a1 in the laser emitting surface plays a positioning role. Each nozzle 62 can be arranged below the lower surface a1 so that the sprayed cleaning medium only covers the lower surface a1 and only cleans the lower surface a1. In this way, the amount of cleaning medium used in each flushing can be reduced, saving the maintenance cost of the container truck positioning system, and the number of nozzles 62 can be reduced to reduce the manufacturing cost.

[0082] Of course, nozzles 62 can also be arranged below the lower surface a1 and above the upper surface a2, so that the cleaning medium sprayed by each nozzle 62 can not only cover the lower surface a1, but also cover the upper surface a2, that is, the entire surface a to be cleaned can be cleaned. In this way, dust is not easy to accumulate on the upper surface a2. When a fault occurs on the lower surface a1, the radar 1 can be rotated so that the upper surface a2 faces downward as a working surface, thereby ensuring the continuous operation of the radar 1 and reducing the operating cost of the container truck positioning system.

[0083] Please combine Figure 7 and Figure 8 It is understood that the nozzle 62 can be set to multiple, for example, two groups can be set, each group can be provided with two nozzles 62, four nozzles 62 correspond to four cleaning pipes 61, so that two mounting racks 63 can be set, and the connecting member 64 can be a one-to-four connecting member, that is, the main joint 641 is connected to four branch joints 642. Specifically, each mounting rack 63 can be used to install a group of nozzles 62, and the two mounting racks 63 can be symmetrically arranged about the vertical section through the axis d of the radar 1. One end of the two first mounting plates 631 can be fixed on the mounting surface c of the base 3, and the other end can extend to the left or right side of the base 3 to extend out of the base 3. The connecting member 64 can be arranged in the middle of the rear of the base 3, that is, the axis of its main joint 641 can coincide with the axis d, and the four branch joints 642 are respectively connected to the four cleaning pipes 61, and the four cleaning pipes 61 extend to the outside of the four mounting sub-plates 6322 respectively. The four nozzles 62 are respectively penetrated and fixed to the four mounting sub-plates 6322. In this way, the structural stability and rigidity of the entire cleaning assembly 6 are higher and more compact, which can further improve the cleaning effect and the stability of the cleaning operation.

[0084] It is worth noting that the plurality of nozzles 62 may also be evenly distributed along the outer circumference of the radar 1 , so that the cleaning medium sprayed by the nozzles 62 is more evenly distributed, which is beneficial to improving the cleaning effect.

[0085] In actual setting, the angle between the spray direction of the nozzle 62 and the axis d is not limited, for example, it can be 30-45 degrees, which can further improve the cleaning effect.

[0086] The cleaning medium storage device 4 provided in the embodiment of the present application is used to store cleaning medium, and its structural form is not limited, for example, it can be a storage tank or a storage box; the cleaning medium is a medium that can be used to clean the radar 1, which can be a liquid, a gas, or a solid, without specific limitation; the cleaning medium storage device 4 can be arranged above the nozzle 62, and gravity is used to transport the cleaning medium to the nozzle 62 for spraying. Of course, a pump can also be arranged to pump the cleaning medium to the nozzle 62, without specific limitation.

[0087] In the examples provided in this application, please refer to Figure 1 The cleaning medium storage device 4 can be a liquid storage tank, the cleaning medium can be a liquid, and the radar cleaning device can also include a cleaning pump 5. The outlet of the liquid storage tank is connected to the inlet of the cleaning pump 5, and the outlet of the cleaning pump 5 is connected to the inlet of the cleaning pipe 61. The outlet of the cleaning pump 5 is specifically connected to the upper end of the delivery pipe 7, and the lower end of the delivery pipe 7 is connected to the main joint 641 of the connecting piece 64. The specifications of the delivery pipe 7 are not limited, for example, it can be a 4×7mm water pipe.

[0088] When in use, the cleaning operation can be turned on and off by controlling the opening and closing of the cleaning pump 5, which makes the operation more convenient. The cleaning medium can also be pressurized by the cleaning pump 5 before being transported, and the transportation efficiency is relatively high, which can enhance the cleaning effect and cleaning efficiency of the nozzle 62. The flow rate of the cleaning medium pumped by the cleaning pump 5 can also be adjusted as needed, which makes it more applicable.

[0089] It is worth noting that the opening, closing and flow adjustment of the cleaning pump 5 can be controlled by corresponding switches, or can be automatically controlled by setting a controller, without specific limitation.

[0090] As an optional solution, the radar cleaning device also includes a controller. In this way, the cleaning pump 5 can be automatically turned on or off by the controller, and the corresponding flow rate can be automatically controlled. The cleaning time interval can also be set according to demand to automatically clean the radar 1 regularly to ensure the smooth operation of the radar 1.

[0091] In actual settings, when the container truck positioning system has more than two radars 1, each radar 1 can be equipped with a cleaning component 6, and each radar 1 can be configured with a set of cleaning medium storage device 4, cleaning pump 5 and controller, or several radars 1 can share a set of cleaning medium storage device 4, cleaning pump 5 and controller, without specific restrictions.

[0092] In actual settings, the controller may be a controller specially configured to control the cleaning operation, or may be a controller of a container truck positioning system, which may be as follows: Figure 1 As shown, it is arranged in the control box 8 of the container truck positioning system. In this way, no additional controller is required, which can save costs.

[0093] Please refer to Figure 1 The quay bridge 2 has a connecting beam 21 and a railing 22. The railing 22 is arranged above the connecting beam 21. The radar 1 can be arranged on the connecting beam 21 through the base 3. In actual arrangement, the locations of the cleaning medium storage device 4, the cleaning pump 5 and the control box 8 are not limited. For example, they can be arranged on the connecting beam 21, or they can be arranged on the connecting beam 21. Figure 1 It is shown as being arranged on the railing 22 .

[0094] The working principle of the radar cleaning device provided in the above embodiment of the present application is described below with reference to the accompanying drawings:

[0095] When in use, the cleaning pump 5 can be turned on by the controller;

[0096] The cleaning pump 5 delivers the liquid in the liquid storage tank to the connecting piece 64 through the delivery pipe 7, and the water is distributed to the four cleaning pipes 61 through the connecting piece 64, and finally the cleaning liquid is sprayed from all directions to the surface a to be cleaned by the four nozzles 62 to rinse the surface a to be cleaned;

[0097] After cleaning is completed, the cleaning pump 5 is turned off by the controller, and the residual cleaning liquid on the surface can be evaporated by the heat generated by the laser radar itself, and then the laser radar resumes working.

[0098] In the embodiment of the present application, the rated power supply voltage of the cleaning pump 5 can be 12 / 24V DC voltage, and the power supply can be drawn from the control box 8 of the container truck positioning system. The rated power of the cleaning pump 5 is 50-100W, which can meet the automatic flushing requirements of the radar 1, and can prevent the impact force of the cleaning liquid flow from being too large, so that the radar 1 is not easily damaged by the impact of the cleaning liquid flow. According to actual tests, for a radar 1, each flushing can consume 900~1000mL of cleaning liquid, and the design capacity of the liquid storage tank can be 5L. Once the cleaning liquid is fully stored, it can be flushed 5~6 times, which can not only reduce the maintenance cost caused by frequent addition of cleaning liquid, but also prevent the cleaning liquid in the liquid storage tank from being lost and wasted due to long-term storage.

[0099] In an embodiment of the present application, a container truck positioning system is also provided, comprising a radar 1 and the radar cleaning device in all the above embodiments.

[0100] Since the radar cleaning device in the above embodiment can clean the radar 1 efficiently and automatically, and the manufacturing cost and cleaning cost are low, the radar 1 in the container truck positioning system provided in the embodiment of the present application is not easily affected by dust on the working area, and can perform positioning work continuously and stably, and the operation and maintenance cost is also low.

[0101] The principles and implementation methods of the present application are described in this article using specific examples. The description of the above embodiments is only used to help understand the device and its core idea of ​​the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
