Description

Technical Field

[0001] This utility model relates to the field of intelligent loading arm technology, and more specifically, to an intelligent loading arm for automatic quantitative loading. Background Technology

[0002] Loading arms are specialized equipment used in the petrochemical industry for loading and unloading fluids. Also known as fluid loading arms, they are mobile devices that use rotary joints to connect with rigid pipes and elbows to transfer liquid media between trains, tank cars, and storage and transportation pipelines on trestle bridges.

[0003] A search revealed that Chinese patent CN223073915U discloses "a fully automatic loading arm, comprising a column, an inner arm pipe, an outer arm pipe, a vertical pipe, an intelligent control console, an inner arm connecting pipe, and an outer arm connecting pipe. The middle part of the column is connected to the inlet pipe via a first connecting plate. The top of the inlet pipe is connected to the inner arm connecting pipe via a first rotary joint. One side of the top of the inner arm connecting pipe is welded to the inner arm pipe. One end of the inner arm pipe is connected to the outer arm connecting pipe via a second rotary joint. The outer arm connecting pipe is connected to the outer arm pipe via a third rotary joint. The outer arm pipe is connected to the vertical pipe via a fourth rotary joint. This utility model's loading arm can achieve fully automatic deployment and retraction through three driving devices, exhibiting high flexibility and good stability. The use of a spring cylinder balancing mechanism, a reinforcing beam, and a vertical pipe return control mechanism improves the overall stability of the loading arm during operation." However, it still has the following drawbacks: Although the loading arm can automatically expand and contract, its functionality is relatively weak. In the actual loading process, it cannot support the pre-setting of the total fluid volume before loading, nor can it automatically terminate the operation process when the loading volume reaches the preset value. This forces operators to monitor the flow data throughout the process, rely on manual experience to judge the loading progress, and manually stop the equipment.

[0004] To address this, a smart loading arm with automatic quantitative loading is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing loading arms cannot support pre-setting the total fluid volume before loading, nor can they automatically terminate the operation process when the loading volume reaches the preset value, forcing operators to monitor the flow data throughout the process, rely on manual experience to judge the loading progress, and manually stop the equipment. This invention provides an intelligent loading arm with automatic quantitative loading to solve the above problems.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: an intelligent loading arm for automatic quantitative loading, comprising: a support frame, wherein a monitoring component for monitoring fluid flow is provided on the support frame, a shut-off component for automatically closing the pipeline to prevent continuous fluid delivery is provided on one side of the monitoring component, and a control component for controlling the monitoring component and the shut-off component is provided on one side of the shut-off component.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0017] Example: Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment proposes an intelligent loading arm for automatic quantitative loading, including: a support frame 1, a monitoring component 2 for monitoring fluid flow rate is provided on the support frame 1, a shut-off component 3 for automatically closing the pipeline to prevent continuous fluid delivery is provided on one side of the monitoring component 2, and a control component 4 for controlling the monitoring component 2 and the shut-off component 3 is provided on one side of the shut-off component 3. like Figure 4 As shown, the monitoring component 2 includes an inlet pipe 201 fixedly connected to one side of the support frame 1. A pipe body 202 is bolted to one side of the inlet pipe 201. An electromagnetic flow meter 203 is fixedly installed on the outside of the pipe body 202. Lugs 204 are symmetrically fixed on one side of the pipe body 202. A display screen 205 is bolted to the electromagnetic flow meter 203. In use, fluid flows into the pipe body 202 through the inlet pipe 201. Based on the principle of electromagnetic induction, the electromagnetic flow meter 203 can accurately monitor the real-time flow rate of the fluid as it flows in the pipe and display it on the display screen 205. Operators can read the flow rate on-site without the need for other equipment, facilitating real-time monitoring of the loading progress. The model of the electromagnetic flow meter 203 is E+HPromag50W.

[0018] like Figure 3 As shown, the shut-off assembly 3 includes a connecting pipe 301 bolted to the other side of the pipe body 202. A valve body 302 is bolted to the other side of the connecting pipe 301. A valve stem 303 is rotatably connected to the top of the valve body 302, passing through the valve body 302 and extending into its interior. A ball 304 is fixedly connected to the end of the valve stem 303. A first bend 305 is fixedly connected to the other side of the valve body 302. In use, when it is necessary to close the fluid passage and stop the loading operation, the rotation of the valve stem 303 will cause the ball 304 to rotate inside the valve body 302. The rotation of the valve stem 303 will in turn cause the ball 304, fixed at its end, to rotate inside the valve body 302. When the ball 304 rotates 90 degrees, the through hole on the ball 304 is completely misaligned with the inlet and outlet of the valve body 302. The ball 304 completely blocks the fluid passage inside the valve body 302, preventing fluid from continuing to pass through, thereby achieving the purpose of closing the fluid passage and stopping the loading operation.

[0019] like Figure 5As shown, the control component 4 includes a frame 401 fixedly connected to the top of the valve body 302. A servo motor 402 is fixedly installed at the bottom of the frame 401. The output end of the servo motor 402 is fixedly connected to the end of the valve stem 303 through a coupling. A PLC controller 403 is fixedly connected to the top of the frame 401. The servo motor 402 and the electromagnetic flowmeter 203 are both electrically connected to the PLC controller 403. In use, the total amount of fluid required for this loading is first set on the PLC controller 403. During the loading process, the electromagnetic flowmeter 203 starts to monitor the fluid flow rate in real time. Based on the principle of electromagnetic induction, the electromagnetic flowmeter 203 converts the fluid flow information into a corresponding electrical signal and continuously transmits the signal to the PLC controller 403 through an electrical connection. After receiving the electrical signal from the electromagnetic flowmeter 203, the PLC controller 403 processes and analyzes it. When the accumulated loaded flow reaches the preset loading total, the PLC controller 403 will immediately issue a control command. This command is transmitted to the servo motor 402 through an electrical connection. After receiving the command, the servo motor 402 starts to run. When the ball 304 rotates to a specific position, the fluid channel inside the valve body 302 is completely closed, thereby stopping the continued delivery of fluid and achieving the purpose of automatic quantitative loading.

[0020] like Figure 2 As shown, the other end of the first bend 305 is fixedly connected to the second bend 5 via a rotary joint. The other end of the second bend 5 is fixedly connected to the third bend 6 via a rotary joint. The other end of the third bend 6 is fixedly connected to the fourth bend 7 via a rotary joint. A solenoid valve 8 is fixedly connected to the fourth bend 7, and the solenoid valve 8 is electrically connected to the PLC controller 403. In use, when the accumulated loaded flow reaches the preset total loading volume, the PLC controller 403 simultaneously issues two control commands. One command drives the servo motor 402 to close the fluid passage inside the valve body 302, and the other command drives the solenoid valve 8 to close simultaneously, thereby stopping the continued delivery of fluid and preventing the liquid remaining in the second bend 5, third bend 6, and fourth bend 7 from flowing out.

[0021] like Figure 3 As shown, sealing rings 9 are symmetrically arranged on the inner wall of the valve body 302, and the sealing rings 9 are located on one side of the ball 304. In use, when the ball 304 is rotated to stop fluid delivery, the sealing rings 9 will fit tightly against the surface of the ball 304 to prevent fluid leakage.

[0022] like Figure 2 As shown, a sealing cap 10 is fixedly installed on the fourth bend 7, and the sealing cap 10 is located on one side of the solenoid valve 8. The fluid flows sequentially through the first bend 305, the second bend 5, and the third bend 6 before entering the fourth bend 7, and finally is injected into the tank truck. The sealing cap 10 makes it difficult for the raw material to evaporate from the tank opening.

[0023] like Figure 2 As shown, a spring cylinder balancing mechanism 11 is hinged to one side of the fourth bend 7, and the other end of the spring cylinder balancing mechanism 11 is hinged to the third bend 6. During fluid transportation, the pressure and flow rate of the fluid may change continuously, generating dynamic impact forces. The spring cylinder balancing mechanism 11 can respond to these dynamic changes in a timely manner, buffering and balancing these impact forces through the elastic force of the spring, reducing the swaying and displacement of the fourth bend 7 and the third bend 6, and keeping the entire pipeline system stable.

[0024] Working Principle: This utility model provides an intelligent loading arm for automatic quantitative loading. In use: Step 1: First, set the total amount of fluid required for this loading on the PLC controller 403. During the loading process, the electromagnetic flowmeter 203 starts monitoring the fluid flow rate in real time. Based on the principle of electromagnetic induction, the electromagnetic flowmeter 203 converts the fluid flow information into a corresponding electrical signal and continuously transmits this signal to the PLC controller 403 via electrical connection. Step 2: After receiving the electrical signal from the electromagnetic flowmeter 203, the PLC controller 403 processes and analyzes it. When the accumulated loaded flow rate reaches the preset loading total, the PLC controller 403 immediately issues a control command. One command is transmitted to the servo motor 402 via electrical connection. After receiving the command, the servo motor 402 starts operating. When the ball 304 rotates to a specific position, the fluid channel inside the valve body 302 is completely closed. Another command drives the solenoid valve 8 to close synchronously, thereby stopping the continued delivery of fluid and preventing the liquid remaining in the second bend 5, third bend 6, and fourth bend 7 from flowing out.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
