Description

Technical Field

[0001] This utility model relates to the field of alarm device technology, specifically an alarm device for residual liquid in an oil delivery arm. Background Technology

[0002] Oil transfer arm residual liquid refers to the oil remaining inside the oil transfer arm during the oil transportation process. An oil transfer arm is a device used to transfer oil from oil tankers, tank trucks, or oil depots to storage tanks or pipelines. Due to the structure of the oil transfer arm and the transportation process, a small amount of oil may remain inside the arm after transportation; this residual oil is called residual liquid. To reduce residual oil in the oil transfer arm, a residual liquid alarm device is installed to detect the amount of residual oil inside the arm.

[0003] Currently, commonly used oil pump arm residual fluid alarm devices provide power to the alarm by wrapping wires around the oil pump arm. While this method is simple and convenient, the exposed wires will oxidize and corrode, leading to open circuits and causing the oil pump arm residual fluid alarm device to malfunction.

[0004] Therefore, we propose an oil delivery arm residual liquid alarm device to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] like Figure 1-4 As shown in the figure, an embodiment of the present invention provides an oil delivery arm residual liquid alarm device, including an oil delivery arm body 1. A mounting base 2 is fixedly mounted on the upper surface of the oil delivery arm body 1. A connecting plate 3 is mounted on the upper surface of the mounting base 2. A connecting shaft 4 is mounted on the inner side of the oil delivery arm body 1. One end of the connecting shaft 4 is rotatably connected to the inner wall of the oil delivery arm body 1. Multiple water flow plates 5 and multiple water level sensors 6 are sequentially fixedly mounted on the outer wall of the connecting shaft 4, with the multiple water level sensors 6 located below the multiple water flow plates 5. A water turbine generator 7 is fixedly mounted on the upper surface of the connecting plate 3. The other end of the connecting shaft 4 passes through the mounting base 2 and connects to the water turbine generator 7. A battery pack 8 is fixedly connected to the upper surface of the water turbine generator 7. The water turbine generator 7 and the battery pack 8 are electrically connected. An alarm light housing 9 is mounted above the battery pack 8. Multiple alarm light bodies 10 are sequentially fixedly mounted on the alarm light housing 9. The alarm light bodies 10 are electrically connected to the water level sensors 6.

[0024] The connection shaft 4, water flow plate 5, water turbine generator 7, and battery pack 8 are designed to store the electrical energy required for the alarm light body 10 and water level sensor 6 to operate. This not only saves energy but also reduces the amount of wires wrapped around the oil delivery arm body 1 to power the alarm light body 10 and water level sensor 6, thus preventing the alarm light body 10 and water level sensor 6 from stopping due to wire breakage. In addition, the water level sensor 6 detects the oil level inside the oil delivery arm body 1, and the alarm light body 10 provides an alarm indication when the water level sensor 6 detects an appropriate oil level.

[0025] A support frame 11 is provided between the alarm light housing 9 and the battery pack 8. A mounting plate 12 is fixedly installed on the lower end face of the support frame 11, and the mounting plate 12 is fixedly connected to the upper end face of the battery pack 8. The alarm light housing 9 is rotatably mounted on the upper end face of the support frame 11. A servo motor 13 is fixedly installed on the upper end face of the battery pack 8. The servo motor 13 is located inside the support frame 11, and the output end of the servo motor 13 passes through the support frame 11 and connects with the alarm light housing 9.

[0026] The support frame 11 supports the alarm light housing 9, and the servo motor 13 drives the alarm light body 10 to rotate. The rotation of the alarm light body 10 causes the alarm light to dazzle, thereby increasing the staff's attention to the light emitted by the alarm light body 10.

[0027] A protective shell 14 is provided above the mounting base 2, and the protective shell 14 covers the connecting plate 3. A fixing plate 15 is fixedly provided on the lower end face of the protective shell 14, and the fixing plate 15 is fixedly connected to the upper end face of the connecting plate 3. A positioning block 16 is fixedly provided on the lower end face of the connecting plate 3, and the positioning block 16 is inserted into the mounting base 2.

[0028] The protective shell 14 serves to protect the alarm light body 10, preventing external objects from bumping into the alarm light body 10 or dust and oil stains from directly adhering to the alarm light body 10.

[0029] A heat insulation plate 17 is provided between the servo motor 13 and the battery pack 8, and the heat insulation plate 17 is connected to both the servo motor 13 and the battery pack 8. The heat insulation plate 17 is provided to prevent the heat generated by the servo motor 13 during operation from affecting the battery pack 8.

[0030] The working principle of this practical application is as follows:

[0031] When the oil delivery arm 1 is delivering oil, the connecting shaft 4 rotates under the flow of oil via the water flow plate 5. The rotation of the connecting shaft 4 drives the water turbine generator 7 to rotate, which generates electrical energy. This electrical energy is stored in the battery pack 8 and used to power the alarm light body 10, the water level sensor 6, and the servo motor 13. In addition, the water level sensor 6 detects the liquid level inside the oil delivery arm 1. When the oil delivery arm 1 stops delivering oil, the oil inside the oil delivery arm 1 will gradually decrease. When the oil level in the oil delivery arm body 1 is lower than the water level sensor 6, and the oil level in the oil delivery arm body 1 is at its lowest point, the water level sensor 6 will transmit an electrical signal to the alarm light body 10 and the servo motor 13. The alarm light body 10 will then light up to trigger an alarm. The start of the servo motor 13 will cause the alarm light housing 9 to rotate, and the rotation of the alarm light housing 9 will cause the alarm light body 10 to rotate. The rotation of the alarm light body 10 will cause the alarm lights to dazzle, thereby increasing the attention of the staff to the light emitted by the alarm light body 10.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
