[0022] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the illustrations, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0023] Such as Figure 1 And Figure 2As shown in the figure, this embodiment provides an electronic detection fuel tank flatness alarm device, which can measure the flatness of the surface of the object to be measured. In this embodiment, the object to be measured is the inner bottom plate of a ship fuel tank.

[0024] The device includes a traveling mechanism 1, a detection mechanism, a display member, an alarm mechanism, and a printing mechanism. The traveling mechanism 1 in this embodiment is a robotic cart that can be controlled by a remote controller. For example, the remote controller controls the robotic cart via Bluetooth. Under the control of the remote controller, the robotic cart can perform actions such as moving forward, backward, left, right, and turning in circles.

[0025] The detection mechanism includes a power supply 2 and flatness detection heads 3. The number of flatness detection heads 3 is multiple. For example, in this embodiment, the number of flatness detection heads 3 is 9. The multiple flatness detection heads 3 are arranged at intervals along the length direction of the traveling mechanism 1. The distance between two adjacent flatness detection heads 3 is 100 mm. The multiple flatness detection heads 3 are connected to the power supply 2 in a parallel manner. Each flatness detection head 3 is located at the bottom of the traveling mechanism and above the inner bottom plate. When the traveling mechanism 1 is placed on the inner bottom plate, each flatness detection head 3 faces the inner bottom plate. At this time, each flatness detection head 3 can detect the flatness value of the inner bottom plate in the corresponding area. After the flatness detection head 3 completes the measurement, the measured data will be sent to the display member for display. Among them, the flatness of the inner bottom plate can be understood as the concave or convex situation on the surface of the inner bottom plate. When the depression distance of the concave pit on the surface of the inner bottom plate is smaller or the protrusion height of the protrusion is smaller, it means that the flatness of the inner bottom plate is better. The flatness detection head 3 includes a laser sensor. The measurement principle of the flatness detection head 3 is as follows: When measuring the flatness of the inner bottom plate, the laser sensor can measure the distance between itself and the surface of the inner bottom plate. For example, the standard distance between the laser sensor itself and the surface of the inner bottom plate is 6 mm. When the distance measured by the laser sensor is 8 mm, it means that this area is a concave pit. When the distance measured by the laser sensor is 4 mm, it means that this area is a protrusion. When the measured data deviates from the range specified by the standard distance, the flatness of this area does not meet the accuracy requirements.

[0026] During specific measurement, place the device on the surface of the inner bottom plate, and then make the traveling mechanism 1 rotate one week with its own center as the center of the circle. During the rotation of the traveling mechanism 1, the flatness detection head 3 performs the measurement. Then control the traveling mechanism 1 to move forward a certain distance and rotate again to perform the measurement operation. By repeating the above actions, the measurement of the flatness of the entire inner bottom plate surface can be completed.

[0027] In other embodiments, multiple flatness detection heads 3 are arranged in multiple rows along the width direction of the traveling mechanism 1. During specific measurement, make the traveling mechanism 1 move from the bow to the stern of the inner bottom plate. During the movement of the traveling mechanism 1, the flatness detection head 3 performs the measurement.

[0028] The display component includes a controller and a display screen 4. The display screen 4 is electrically connected to the controller, and multiple flatness detection heads 3 are electrically connected to the controller. For example, there are multiple display screens 4, and multiple display screens 4 are all arranged on the traveling mechanism 1, and multiple display screens 4 and multiple flatness detection heads 3 are in one-to-one correspondence. Each display screen 4 can be used to display the measurement situation of each flatness detection head 3. After each flatness detection head 3 measures the flatness value, it will send the data to the controller. The controller analyzes the measurement data. If the measured data exceeds the accuracy requirement, the controller will send the deviation value to the corresponding display screen 4 for display. The operator can understand the flatness situation of the inner bottom plate through the display component, and then the operator corrects the inner bottom plate according to the measurement situation.

[0029] The alarm mechanism is arranged on the traveling mechanism 1. The number of alarm mechanisms is multiple, and multiple alarm mechanisms are in one-to-one correspondence with multiple flatness detection heads 3. When the value measured by the flatness detection head 3 exceeds the accuracy requirement, the corresponding alarm mechanism will also give an alarm for prompt. The alarm form adopted by the alarm mechanism is at least one of sound and light.

[0030] As Figure 2 shown, specifically, the alarm mechanism includes a support pipe 5, an elastic member 6, a telescopic rod 7, a trigger rod 8, an alarm lamp 9, an upper contact 10, and a lower contact 11. The support pipe 5 is arranged vertically. The top end of the support pipe 5 is fixed to the bottom of the traveling mechanism 1, and the bottom end of the support pipe 5 protrudes from the bottom surface of the traveling mechanism 1. Each flatness detection head 3 is arranged on the side surface of the bottom end of the corresponding support pipe 5.

[0031] A sleeve 51 is arranged inside the support pipe 5. The sleeve 51 is arranged vertically. The top end of the sleeve 51 is closed and the bottom end is open. The bottom end of the sleeve 51 is inserted into the support pipe 5 from the top end of the support pipe 5 and the top end of the sleeve 51 is fixed to the support pipe 5. One end of the telescopic rod 7 slides and is inserted into the support pipe 5 from the bottom end of the support pipe 5 and is inserted into the sleeve 51. The elastic member 6 is located inside the sleeve 51, and both ends of the elastic member 6 are respectively connected to the telescopic rod 7 and the sleeve 51; the other end of the telescopic rod 7 protrudes from the support pipe 5. During measurement, the telescopic rod 7 abuts against the surface of the inner bottom plate under the action of the elastic member 6. When the surface of the inner bottom plate bulges upward, the telescopic rod 7 moves upward, and vice versa, the telescopic rod 7 moves downward.

[0032] The trigger rod 8 is fixed to the side of the telescopic rod 7 and is located inside the support tube 5. The upper contact 10 and the lower contact 11 are fixed to the inner wall of the support tube 5 and are respectively arranged at the upper and lower ends of the trigger rod 8. The trigger rod 8 can be connected to the positive pole of the alarm lamp 9 through an electric wire. Both the upper contact 10 and the lower contact 11 are connected to the negative pole of the alarm lamp 9 through electric wires. The power supply 2 in the detection mechanism can supply power to the circuit composed of the trigger rod 8, the upper contact 10, the lower contact 11 and the alarm lamp 9. During the process of measuring the flatness, if the flatness meets the accuracy requirements, the trigger rod 8 does not contact the upper contact 10 and the lower contact 11, and the alarm lamp 9 does not give an alarm; if the height of the protrusion on the inner bottom plate exceeds the accuracy requirements, the trigger rod 8 moves upward with the telescopic rod 7, and the trigger rod 8 contacts the upper contact 10. At this time, the alarm lamp 9 gives an alarm; if the depression distance of the pit on the inner bottom plate exceeds the accuracy requirements, the trigger rod 8 moves downward with the telescopic rod 7, and the trigger rod 8 contacts the lower contact 11. At this time, the alarm lamp 9 gives an alarm.

[0033] As Figure 1 shown, the inkjet printing mechanism is arranged on the traveling mechanism 1. The inkjet printing mechanism is used to spray marks on the areas of the inner bottom plate that do not meet the accuracy requirements. The inkjet printing mechanism includes an inkjet printing box 12 and a spraying pipe 13. The inkjet printing box 12 is arranged on the side of the traveling mechanism 1. The inkjet printing box 12 stores the lettering solvent, and the inkjet printing box 12 is used to supply materials to the spraying pipe 13. It can be understood that the inkjet printing mechanism further includes a power component that extracts the lettering solvent from the inkjet printing box 12 and sprays the lettering solvent from the spraying pipe 13. The power component is not described here.

[0034] The telescopic rod 7 is hollow inside. A spraying pipe 13 is inserted into each telescopic rod 7. The spraying pipe 13 is arranged in the following way: a hole structure is opened at the top end of the sleeve 51, and one end of the spraying pipe 13 is inserted into the telescopic rod 7 through the hole structure at the top end of the sleeve 51 and passes through the sleeve 51. The other end of the spraying pipe 13 is connected to the inkjet printing box 12. When the controller receives the data measured by the flatness detection head 3, it analyzes the received data. If the measured data exceeds the accuracy requirements, at this time, the controller controls the inkjet printing mechanism to spray marks on the inner bottom plate, and the operator can correct the corresponding position according to the marks.

[0035] Taking the example that multiple flatness detection heads 3 are arranged along the length direction of the traveling mechanism 1, the implementation process of the electronic detection fuel tank flatness alarm device is as follows: First, place the device on the inner bottom plate, and then control the traveling mechanism 1 to rotate one week through the remote control. While the traveling mechanism 1 is rotating, the flatness detection head 3 will measure the flatness of the inner bottom plate and send the measured data to the controller. The controller analyzes the data. If the measured data exceeds the required range, at this time, the controller will make the corresponding display part display the deviation value of the flatness, and the controller controls the inkjet printing mechanism to spray marks on the inner bottom plate. At the same time, the trigger rod 8 in the corresponding alarm mechanism contacts the upper contact 10 or the lower contact 11, and the alarm lamp 9 gives an alarm prompt.

[0036] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
