Description

Technical Field

[0001] This application relates to the field of oil storage technology, and in particular to a detection device and an oil storage equipment. Background Technology

[0002] In industrial production, on-off valves are a common type of equipment. Based on their actuation method, on-off valves can be divided into manual valves and electric valves. Electric valves generate higher current and voltage during operation, making them prone to static electricity and unsuitable for use in locations with high static elimination requirements, such as oil depots. Manual valves, on the other hand, are widely used in oil depots and other locations with high static elimination requirements due to their simple structure, low cost, and lack of static electricity generation during operation.

[0003] In related technologies, storage tanks in oil depots are typically opened or closed using manual gate valves. However, during oil depot operation, when it is necessary to check the status of multiple manual gate valves due to safety requirements or abnormal malfunctions, manual inspection of these valves is usually required. This manual inspection is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0004] This application provides a detection device and an oil storage device. The detection device can check the open or closed state of a manual gate valve. When applied to an oil storage device, this detection device can improve inspection efficiency and reduce the labor intensity of troubleshooting.

[0005] The technical solution is as follows:

[0006] According to a first aspect of the present application, a detection device is provided for detecting the state of a manual gate valve, the manual gate valve including a retractable valve stem. The detection device includes a support member, a detection component, and a signal processing module. The support member includes a first mounting portion and a second mounting portion spaced apart from the first mounting portion along the height direction of the support member. The detection component includes a mounting member, a sensing device, a first trigger fixed to the first mounting portion, and a second trigger fixed to the second mounting portion. The mounting member is fixedly connected to one end of the valve stem so as to be able to retract and move with the valve stem along the height direction of the support member, and has a first position and a second position. The sensing device is fixed to the mounting member. The signal processing module is insulated from the support member and electrically connected to the sensing device.

[0007] When the mounting component is in the first position, the sensing device engages with the first sensing element, and the signal processing module generates a first electrical signal. When the mounting component is in the second position, the sensing device engages with the second sensing element, and the signal processing module generates a second electrical signal different from the first electrical signal.

[0008] The technical solution of this application will be further described below:

[0009] In one embodiment, the support includes a first end and a second end disposed opposite to the first end, a first mounting portion and a second mounting portion being spaced apart between the first end and the second end, and a signal processing module being fixed to the second end.

[0010] In one embodiment, the signal processing module further includes a module body and a flexible conductive line electrically connected to the module body, the flexible conductive line being electrically connected to the sensing device.

[0011] In one embodiment, at least a portion of the flexible conductive wire is helical to allow the flexible conductive wire to stretch or contract in the height direction of the support frame.

[0012] In one embodiment, the detection device further includes a protective cover fixed to the second end, the protective cover and the second end cooperating to form a protective cavity, and the signal processing module is disposed inside the protective cavity.

[0013] In one embodiment, the protective cover has a notch communicating with the protective cavity, and the signal processing module has an electrical first end that cooperates with the notch to form an electrical connection port.

[0014] In one embodiment, the mounting member is slidably connected to the support member and rotatably connected to the valve stem.

[0015] In one embodiment, the support member is provided with a protective channel, the mounting member and the sensing device are slidably disposed in the protective channel, and the valve stem can be inserted into the protective channel.

[0016] In one embodiment, the support includes a sleeve with a protective channel;

[0017] And / or, the first trigger includes a first magnetic ring and is sleeved and fixed to the first mounting portion, and the second trigger includes a second magnetic ring and is sleeved and fixed to the second mounting portion.

[0018] In one embodiment, the sensing device includes a first magnetic sensing element and a second magnetic sensing element disposed at a distance from the first magnetic sensing element along the length of the valve stem.

[0019] When the manual gate valve is in the closed state, the mounting part is in the first position, the first magnetic induction element and the first magnetic ring magnetically cooperate to generate the first induced current;

[0020] When the manual gate valve is in the open state, the mounting part is in the second position, the second magnetic induction element and the second magnetic ring magnetically cooperate to generate a second induced current that is different from the first induced current.

[0021] According to a second aspect of the embodiments of this application, an oil storage device is also provided, including a storage tank, a control device, and a detection device from any of the above embodiments. The storage tank includes a manual gate valve, which includes a retractable valve stem. A mounting member is fixedly connected to one end of the valve stem so that a sensing device moves with the retraction and extension of the valve stem. The control device is electrically connected to a signal processing module.

[0022] When the manual gate valve is in the closed state, the mounting part is in the first position, the sensing device can sense and cooperate with the first triggering element, and the signal processing module sends the first electrical signal to the control device.

[0023] When the manual gate valve is in the open state, the mounting part is in the second position, the sensing device can sense and cooperate with the second triggering element, and the signal processing module sends a second electrical signal different from the first electrical signal to the control device.

[0024] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0025] The manual gate valve of the storage tank moves its stem in and out of the closed and open states. During the installation of the inspection device, a support is mounted on the tank, and a mounting component is connected to the valve stem. This allows the sensing element to move with the valve stem, triggering either a first or second trigger, which in turn generates a corresponding electrical signal from the signal processing module. Specifically, when the manual gate valve is closed, the mounting component is in the first position, the sensing element engages with the first trigger, and the signal processing module sends a first electrical signal to the control device. The control device receives this first electrical signal and determines that the manual gate valve is closed. When the manual gate valve is open, the mounting component is in the second position, the sensing element engages with the second trigger, and the signal processing module sends a second electrical signal (different from the first) to the control device. The control device receives this second electrical signal and determines that the manual gate valve is open. This inspection device can thus check the open or closed state of the manual gate valve, improving inspection efficiency and reducing labor intensity compared to traditional manual inspection methods.

[0035] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0037] To improve the safety of fuel storage, multiple storage tanks are typically placed in fuel depots. This is especially true in the aviation fuel sector, where the large quantities of fuel required for aircraft flights necessitate larger storage tanks for protection.

[0038] In related technologies, oil depot storage tanks are typically opened and closed using manual gate valves. However, during oil depot operation, due to regular safety inspections or in case of abnormal malfunctions, it is necessary to check the status of manual gate valves in multiple tanks. This usually requires inspection personnel to check the status of each manual gate valve in the oil depot. This process requires considerable movement, and for some manual gate valves located higher up, ladders or other tools are needed for climbing. Therefore, manually checking the status of multiple manual gate valves is time-consuming, labor-intensive, and inefficient.

[0039] Based on this, the present invention provides a detection device capable of checking the open or closed state of a manual gate valve. This detection device, when applied to oil storage equipment, can improve inspection efficiency and reduce the labor intensity of troubleshooting.

[0040] To better understand the detection device of this application, an oil storage device using the detection device will be used as an example.

[0041] like Figures 1 to 2 As shown in the embodiments of this application, an oil storage device 10 is provided, including a storage tank 100, a control device 200, and a detection device 300. The storage tank 100 includes a manual gate valve 110, which includes a retractable valve stem 111. During the switching between a closed state and an open state, the manual gate valve 110 of the storage tank 100 can drive the valve stem 111 to extend and retract.

[0042] like Figures 2 to 4As shown, the detection device 300 includes a support member 310, a detection component 320, and a signal processing module 330. The support member 310 includes a first mounting portion 311 and a second mounting portion 312 spaced apart from the first mounting portion 311 along the height direction of the support member 310. The detection component 320 includes a mounting member 321, a sensing device 322, a first trigger member 323 fixed to the first mounting portion 311, and a second trigger member 324 fixed to the second mounting portion 312. The mounting member 321 is fixedly connected to one end of the valve stem 111, allowing it to extend and retract with the valve stem 111 along the height direction of the support member 310, and has a first position and a second position. The sensing device 322 is fixed to the mounting member 321. The signal processing module 330 is insulated from the support member 310 and electrically connected to the sensing device 322. The control device 200 is electrically connected to the signal processing module 330.

[0043] When the manual gate valve 110 is in the closed state, the mounting part 321 is in the first position, the sensing device 322 can sense and cooperate with the first trigger 323, and the signal processing module 330 sends the first electrical signal to the control device 200.

[0044] When the manual gate valve 110 is in the open state, the mounting part 321 is in the second position, the sensing device 322 can sense and cooperate with the second trigger 324, and the signal processing module 330 sends a second electrical signal different from the first electrical signal to the control device 200.

[0045] During the installation of the inspection device on the storage tank 100, the support member 310 is mounted on the storage tank 100, and the mounting member 321 is connected to the valve stem 111, allowing the mounting member 321 to switch between a first position and a second position as the valve stem 111 extends and retracts. During this process, the mounting member 321 also drives the sensing device 322 to extend and retract with the valve stem 111, enabling it to engage with the first trigger 323 or the second trigger 324, thus allowing the signal processing module 330 to generate a corresponding electrical signal. Specifically, when the manual gate valve 110 is in the closed state, the mounting member 321 is in the first position, the sensing device 322 can engage with the first trigger 323, and the signal processing module 330 sends a first electrical signal to the control device 200. The control device 200 receives this first electrical signal and knows that the manual gate valve 110 is in the closed state. When the manual gate valve 110 switches from the closed state to the open state, the valve stem 111 moves towards the second trigger 324. When the manual gate valve 110 is in the open state, the valve stem 111 moves the mounting piece 321 to the second position, causing the sensing device 322 to engage with the second triggering element 324, and the signal processing module 330 to send a second electrical signal, different from the first electrical signal, to the control device 200. The control device 200 receives the second electrical signal and determines that the manual gate valve 110 is in the open state. Thus, this inspection device can check the open or closed state of the manual gate valve 110, improving inspection efficiency and reducing labor intensity compared to traditional manual inspection methods.

[0046] It should be noted that there are many ways to implement the control device, including but not limited to computers, mobile phones, smart speakers, etc.

[0047] It should be noted that the support can be fixed in various ways without interfering with the operation of the manual gate valve.

[0048] In some embodiments, the support is fixed to the storage tank or the ground.

[0049] For example, the support is fixed to the side wall of the storage tank by a cantilever, and suspended above the manual gate valve.

[0050] like Figures 2 to 4 As shown, the extension and retraction direction of the valve stem, the height direction of the support member, and the Z-axis direction are all aligned. That is, the mounting member moves along the Z-axis to switch between a first position and a second position.

[0051] Optionally, in some embodiments, the control device includes a display screen capable of displaying at least the status information of the manual gate valve to clearly inform troubleshooting personnel.

[0052] Optionally, in some embodiments, the control device is a smart speaker, which can at least inform the manual gate valve of its status information via voice.

[0053] Understandably, most storage tanks are quite large, and some manual gate valves are located at high positions. When manually inspecting these valves, ladders or other tools are needed to reach higher locations, making the inspection labor-intensive and inefficient. However, the detection device described in this application can directly detect the open or closed state of the manual gate valve, improving inspection efficiency and reducing labor intensity.

[0054] like Figure 1 As shown, in some embodiments, the oil storage device 10 includes multiple storage tanks 100 and is located within an oil depot. Thus, when a safety inspection of the oil depot is required, or when an abnormal malfunction necessitates checking the status of the manual gate valves 110 of multiple storage tanks 100, the detection device 300 can check the status of each manual gate valve 110 and send the detection information to the control device 200. Inspectors can then promptly complete the inspection of the manual gate valves 110 based on the status information provided by the control device 200, improving inspection efficiency and reducing labor intensity.

[0055] Among them, multiple includes two or more.

[0056] like Figure 2 As shown, in some embodiments, the support member 310 includes a first end 313 and a second end 314 disposed opposite to the first end 313. A first mounting portion 311 and a second mounting portion 312 are spaced apart between the first end 313 and the second end 314, and the signal processing module 330 is fixedly mounted on the second end 314. Thus, the signal processing module 330 is fixedly mounted on the second end 314 and then fixedly connected to the storage tank 100 through the first end 313, thereby placing the signal processing module 330 on the storage tank 100. This is easy to implement and convenient to install.

[0057] In addition, the first mounting part and the second mounting part are spaced apart between the first end and the second end, so that when the valve stem drives the sensing device to move, it will not interfere with the signal processing module, thereby improving the reliability of the status detection of the manual gate valve.

[0058] It should be noted that there are multiple ways to implement the first end, as long as it can be connected to the storage tank.

[0059] like Figure 2As shown, in some embodiments, the signal processing module 330 further includes a module body 331 and a flexible conductive line 332 electrically connected to the module body 331. The flexible conductive line 332 is electrically connected to the sensing device 322. Thus, the flexible conductive line 332 is used to achieve the electrical connection between the module body 331 and the sensing device 322, improving the reliability of the communication connection between the module body 331 and the sensing device 322. Simultaneously, the flexible conductive line 332 is deformable and does not interfere with the movement of the sensing device 322.

[0060] Optionally, such as Figures 2 to 4 As shown, in some embodiments, at least a portion of the flexible conductive wire 332 is spiral-shaped to allow for extension and retraction of the flexible conductive wire 332 along the height direction of the support frame. Thus, when the sensing device 322 approaches the module body 331, the flexible conductive wire 332 contracts, becoming shorter along the height direction of the support frame. Conversely, when the sensing device 322 moves away from the module body 331, the flexible conductive wire 332 extends, becoming longer along the height direction of the support frame. This allows the flexible conductive wire 332 to extend and retract along the height direction of the support frame without entanglement with the sensing device 322 or the valve stem 111, preventing damage.

[0061] Optionally, such as Figure 2 As shown, in some embodiments, the detection device 300 further includes a protective cover 340 fixed to the second end 314. The protective cover 340 and the second end 314 cooperate to form a protective cavity 301, and the signal processing module 330 is disposed within the protective cavity 301. Thus, the protective cavity 301 can effectively protect the signal processing module 330, improving the protection performance of the detection device 300.

[0062] like Figure 2 as well as Figure 3 As shown, in some embodiments, the protective cover 340 has a notch 341 communicating with the protective cavity 301, and the signal processing module 330 has an electrical first end 333 that cooperates with the notch 341 to form an electrical connection port. Thus, when the control device 200 and the signal processing module 330 are wired, the transmission line passes through the notch 341 and is electrically connected to the electrical first end 333.

[0063] One end of the transmission line and the first electrical end 333 are provided with a male connector, and the other end is provided with a female connector that is electrically connected to the male connector.

[0064] It should be noted that there are various ways to implement the electrical first end, including USB connectors, board-to-board connectors, etc.

[0065] It should be noted that there are various ways to connect the mounting component to the valve stem, including but not limited to adhesive bonding, screwing, and swivel connections. For example, the mounting component may have a screw rod fixed to it, and the screw rod may be screwed to the valve stem.

[0066] Optionally, in some embodiments, the manual gate valve includes a valve body communicating with the storage tank, a handle rotatably disposed in the valve body, a gate plate disposed in the valve body, and a valve stem connected to the gate plate. The handle and the valve stem are threadedly connected to drive the valve plate to open or close the valve body.

[0067] In some embodiments, the mounting component is slidably connected to the support component and rotatably connected to the valve stem. In this way, the valve stem can move the mounting component along the height of the support component, but the mounting component will not rotate with the valve stem, making the wired connection between the sensing device and the signal processing module more reliable.

[0068] In conjunction with the aforementioned flexible conductive wire, the smooth movement of the mounting component prevents the flexible conductive wire from tangling around the mounting component.

[0069] like Figure 2 As shown, in some embodiments, the support member 310 is provided with a protective channel 315, and the mounting member 321 and the sensing device 322 are slidably disposed within the protective channel 315, and the valve stem 111 can be inserted into the protective channel 315. In this way, the protective channel 315 can effectively protect the sensing device 322, thereby improving the protection performance of the detection device 300.

[0070] Optionally, in some embodiments, the support 310 includes a sleeve with a protective channel 315. This is easy to implement.

[0071] It should be noted that the trigger and sensing device 322 can be implemented in various ways, including but not limited to photoelectric detection, machine vision detection, contact detection, magnetic induction detection, etc. In some embodiments, the first trigger 323 includes a first magnetic ring and is sleeved and fixed to the first mounting part 311, and the second trigger 324 includes a second magnetic ring and is sleeved and fixed to the second mounting part 312. In this way, the sensing device 322 and the magnetic ring cooperate magnetically to generate a corresponding electrical signal for the signal processing module 330. For example, the signal processing module 330 is an electrical signal sensor, etc.

[0072] It should be noted that the signal processing module 330 can generate different electrical signals based on changes in current, voltage, resistance, etc. generated by the sensing device 322.

[0073] like Figures 2 to 4As shown, in some embodiments, the sensing device 322 includes a first magnetic sensing element 3221 and a second magnetic sensing element 3222 spaced apart from the first magnetic sensing element 3221 along the length of the valve stem 111. When the manual gate valve 110 is in the closed state, the mounting member 321 is in a first position, the first magnetic sensing element 3221 magnetically engages with the first magnetic ring, and generates a first induced current. Thus, the signal processing module 330 can generate a first electrical signal based on the first induced current.

[0074] When the manual gate valve 110 is in the open state, the mounting component 321 is in the second position, and the second magnetic induction element 3222 engages with the second magnetic ring to generate a second induced current different from the first induced current. Thus, the signal processing module 330 can generate a second electrical signal based on the second induced current.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this application, and these modifications and improvements all fall within the protection scope of this application.
