Description

Technical Field

[0002] A skid-mounted filling device is a device used for the rapid filling and filling of liquids or gases. It is commonly used in industries such as chemical, petroleum, and natural gas. Its main features are that the equipment is integrated and modular, and can be flexibly moved and installed as needed.

Manual inspection is inefficient and greatly affected by human factors, making it easy to miss leaks. A single pressure sensor can only detect whether there are pressure changes in the pipeline, but it is difficult to accurately determine the degree of leakage and provide timely and detailed early warning information, thus failing to meet the needs of actual use. Therefore, a skid-mounted filling device with a pipeline leak early warning mechanism is proposed to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figures 1-5As shown, a skid-mounted filling device with a pipeline leak warning mechanism includes a skid-mounted base 1. Support columns 2 are fixedly connected to the four corners of the upper end of the skid-mounted base 1. A top plate 3 is fixedly connected to the upper end of each support column 2. Three side plates 4 are fixedly connected between the skid-mounted base 1 and the top plate 3. An explosion-proof partition 5 is fixedly connected between the top plate 3 and the skid-mounted base 1. The explosion-proof partition 5 divides the area between the top plate 3 and the skid-mounted base 1 into a liquid storage area 6 and an electrical area 7. The left side of the explosion-proof partition 5 is fixedly connected to... A support plate 8 is provided. A liquid storage tank 9 is fixedly connected to the upper end of the skid-mounted base 1. A liquid outlet pipe 10 is connected to the lower end of the liquid storage tank 9. The other end of the liquid outlet pipe 10 passes through the lower end of the support plate 8 and is fixedly connected to a centrifugal pump 11. The centrifugal pump 11 is fixedly installed on the upper end of the support plate 8. A valve 12 is provided on the centrifugal pump 11. A branch pipe 17 is connected to the outer surface of the liquid outlet pipe 10. A piston 18 is slidably connected inside the branch pipe 17. A connecting rod 1 is fixedly connected to the end of the piston 18 away from the liquid outlet pipe 10. 9. The other end of the connecting rod 19 passes through the end of the branch pipe 17 away from the outlet pipe 10 and is fixedly connected to a movable plate 20. The outer surface of the branch pipe 17 is fixedly connected to a first fixed plate 21. The end of the first fixed plate 21 near the movable plate 20 is fixedly connected to two symmetrically distributed guide posts 22. The other end of the guide posts 22 is fixedly connected to a second fixed plate 23. The movable plate 20 is slidably connected to the outer surface of the guide posts 22. Two symmetrically distributed springs 24 are fixedly connected between the movable plate 20 and the second fixed plate 23. The outer surface of the movable plate 20 is fixedly connected to a first conductive terminal 25, a second conductive terminal 26, and a third conductive terminal 27. The outer surface of the first fixed plate 21 is fixedly connected to a first conductive block 28, a second conductive block 29, and a third conductive block 30 with successively decreasing lengths. Three warning indicator lights 31 are fixedly installed on the upper end of the top plate 3. The first conductive block 28, the second conductive block 29, and the third conductive block 30 are electrically connected to the three warning indicator lights 31 respectively.

[0023] Furthermore, the output end of the centrifugal pump 11 is fixedly connected to an infusion pipe 13, and the other end of the infusion pipe 13 passes through the right end of the left side plate 4 and is fixedly connected to a first flange interface 14.

[0024] Furthermore, the upper end of the storage tank 9 is fixedly connected to an inlet pipe 15, and the other end of the inlet pipe 15 passes through the right end of the left side plate 4 and is fixedly connected to a second flange interface 16.

[0025] Furthermore, the storage tank 9 is used to store the fluid medium, the outlet pipe 10 is used to discharge the medium in the storage tank 9, the centrifugal pump 11 is used to provide fluid transport power, the valve 12 is used to control the flow of fluid, the first flange interface 14 is used to connect the fluid output component, such as the filling gun, and the second flange interface 16 is used to connect the medium supply equipment to facilitate the replenishment of fluid medium into the storage tank 9.

[0026] Furthermore, the branch pipe 17 is used to sense changes in the pressure of the outlet pipe 10 in real time. Under normal delivery conditions, the pressure inside the outlet pipe 10 tends to be stable, and the position of the piston 18 remains basically unchanged. When the outlet pipe 10 leaks, the pressure inside the branch pipe 17 decreases. Under the action of the spring force of the spring 24, the movable plate 20 will push the connecting rod 19 to move the piston 18 closer to the outlet pipe 10. At this time, the movable plate 20 will move the first conductive terminal 25, the second conductive terminal 26, and the third conductive terminal 27 to gradually approach the first conductive block 28, the second conductive block 29, and the third conductive block 30. Due to the different degrees of leakage, the degree of pressure reduction inside the branch pipe 17 is also different, and the lengths of the first conductive block 28, the second conductive block 29, and the third conductive block 30 decrease sequentially. When the outlet pipe 10 has a slight leak, the first conductive terminal 25 will first contact the first conductive block 28 to form a contact. When a closed loop is formed, the leftmost warning indicator 31 lights up. If a moderate leak occurs, the piston 18 will move further, and the second conductive terminal 26 will contact the second conductive block 29 to form a closed loop. At this time, the middle warning indicator 31 will also light up. If a severe leak occurs, the piston 18 will move further, and the third conductive terminal 27 will contact the third conductive block 30. At this time, all three warning indicator 31s will light up. Through the mechanical contact-type graded warning structure formed by the first conductive block 28, the second conductive block 29, and the third conductive block 30, and the first conductive terminal 25, the second conductive terminal 26, and the third conductive terminal 27, different warning levels can be triggered according to the pressure change of the outlet pipe 10, thereby realizing a visual warning of micro-leakage, moderate leak, and severe leak, which makes it convenient for staff to take corresponding measures in a timely manner according to the different degrees of leakage.

[0027] Furthermore, lifting rings 33 are fixedly connected to the four corners of the upper end of the top plate 3. The installation of lifting rings 33 facilitates the hoisting of the entire device.

[0028] Furthermore, the left end of the explosion-proof partition 5 is provided with multiple evenly distributed wire-passing holes 501. The inner wall of the wire-passing hole 501 is fixedly connected with an elastic rubber pad made of stainless steel plate, which is used to separate the liquid storage area 6 and the electrical area 7. The wire-passing hole 501 is designed to facilitate the connection of the cable through the explosion-proof partition 5 to the equipment in the liquid storage area 6. After the cable passes through, the elastic rubber pad on the inner wall of the wire-passing hole 501 is tightly attached to the outer surface of the cable to form a sealing structure, which prevents the flammable and explosive gas in the liquid storage area 6 from entering the electrical area 7, thereby preventing electrical sparks from igniting the gas.

[0029] Furthermore, each of the two front support columns 2 is hinged with an inspection door 32. There are two inspection doors 32, corresponding to the liquid storage area 6 and the electrical area 7 respectively.

[0030] Working principle: Under normal operating conditions, the medium flows into the centrifugal pump 11 through the outlet pipe 10. The centrifugal pump 11 pressurizes the medium and delivers it to the external receiving equipment via the delivery pipe 13. The piston 18 is in its initial position. When a leak occurs in the outlet pipe 10, the pressure in the branch pipe 17 decreases. Under the action of the spring 24, the movable plate 20 pushes the connecting rod 19, causing the piston 18 to approach the outlet pipe 10. At this time, the movable plate 20 will cause the first conductive terminal 25, the second conductive terminal 26, and the third conductive terminal 27 to gradually approach the first conductive block 28, the second conductive block 29, and the third conductive block 30. Due to different degrees of leakage, the degree of pressure reduction in the branch pipe 17 also varies, and the lengths of the first conductive block 28, the second conductive block 29, and the third conductive block 30 decrease sequentially. When a slight leak occurs in the outlet pipe 10, the first conductive terminal 25 will first contact the first conductive block 28. A closed loop is formed, at which point the leftmost warning indicator 31 lights up. If a moderate leak occurs, the movement distance of the piston 18 will increase further, at which point the second conductive terminal 26 will contact the second conductive block 29 to form a closed loop, and the middle warning indicator 31 will also light up. If a severe leak occurs, the movement distance of the piston 18 will increase again, and the third conductive terminal 27 will contact the third conductive block 30, at which point all three warning indicator 31s will light up. Through the mechanical contact-type graded warning structure formed by the first conductive block 28, the second conductive block 29, and the third conductive block 30, and the first conductive terminal 25, the second conductive terminal 26, and the third conductive terminal 27, different warning levels can be triggered according to the pressure changes of the liquid outlet pipe 10, thereby realizing a visual warning of micro-leakage, moderate leak, and severe leak, which makes it convenient for staff to take corresponding measures in a timely manner according to the different degrees of leakage.
