Description

[0001] The present application relates to the technical field of oil storage, in particular to a detection device and an oil storage equipment. BACKGROUND

[0002] In industrial production, a switch valve is a very common device. According to the driving mode, the switch valve can be divided into a manual valve and an electric valve. In the running process of the electric valve, the current and voltage are large, and static electricity is easily generated, so the electric valve cannot be applied to places such as oil depots that have high requirements for static electricity removal. The manual valve is widely used in places such as oil depots that have high requirements for static electricity removal because of its simple structure, low cost, and no static electricity generated in the operation process.

[0003] In the related art, the storage tank in the oil depot is usually opened or closed by a manual gate valve. When the safety operation requirement or abnormal failure is encountered during the operation of the oil depot, and the states of multiple manual gate valves in the oil depot need to be checked, manual checking of the multiple manual gate valves is usually required. However, manual checking is time-consuming and labor-intensive, and the checking efficiency is low. SUMMARY

Specifically, when the manual gate valve is in the closed state, the mounting member is in the first position, the inductive device can be inductively matched with the first trigger, and the signal processing module sends the first electric signal to the control device.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments (or “embodiments”) of the present application will be described clearly and completely in combination with the drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0036] If the application embodiments involve terms of direction indication or position relationship (for example, up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative position relationship, motion condition, etc. between components in a certain specific posture (as shown in the drawings); if the specific posture changes, the direction indication or position relationship will also change accordingly. In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0037] In order to improve the safety of fuel storage, multiple storage tanks are usually placed in an oil depot for storage. In the field of aviation oil, due to the large amount of oil required for aircraft flight, the volume of the storage tank for storing aviation oil is also large, and a larger oil depot is also needed to protect the storage tank.

[0038] In the related art, the storage tank in the oil depot is usually opened or closed through a manual gate valve. When the manual gate valve state of multiple storage tanks in the oil depot needs to be checked due to the need for regular inspection for safe operation or abnormal failure, etc. during the operation of the oil depot, the state of each manual gate valve in the oil depot needs to be detected by the inspector. In this process, a large range of walking is required. And for some high-positioned manual gate valves, a ladder tool needs to be used for climbing. Therefore, when manually checking the state of multiple manual gate valves, time and labor are consumed, and the checking efficiency is low.

[0039] Based on this, the application provides a detection device which can check the opening state or closing state of the manual gate valve. The detection device is applied to the oil storage equipment, which can improve the checking efficiency and reduce the labor intensity of checking.

[0040] In order to better understand the detection device of the application, the oil storage equipment to which the detection device is applied is described.

[0041] As shown in FIG. 1, Figures 1 to 2 In the embodiments of the application, an oil storage equipment 10 is provided, which includes a storage tank 100, a control device 200 and a detection device 300. The storage tank 100 includes a manual gate valve 110, and the manual gate valve 110 includes a telescopic valve rod 111. During the switching between the closing state and the opening state of the manual gate valve 110 of the storage tank 100, the valve rod 111 can be driven to perform telescopic motion.

[0042] As shown in FIG. 2, Figures 2 to 4As shown, the detection device 300 comprises a support 310, a detection assembly 320 and a signal processing module 330. The support 310 comprises a first mounting portion 311 and a second mounting portion 312 which is spaced apart from the first mounting portion 311 along the height direction of the support 310. The detection assembly 320 comprises 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 so as to be able to move along the height direction of the support 310 with the valve stem 111 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 insulatively arranged on the support 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 member 321 is in the first position, the sensing device 322 can be inducted with the first trigger member 323, and the signal processing module 330 sends a first electric signal to the control device 200.

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

[0045] During installation of the inspection device on the storage tank 100, the support 310 is arranged on the storage tank 100, and the mounting 321 is connected with the valve rod 111, so that the mounting 321 is switched between the first position and the second position along with the extension and retraction movement of the valve rod 111. During this process, the mounting 321 also drives the inductive device 322 to extend and retract along with the valve rod 111, so as to realize triggering cooperation with the first trigger 323 or the second trigger 324, so that the signal processing module 330 can generate a corresponding electrical signal. Specifically, when the manual gate valve 110 is in the closed state, the mounting 321 is in the first position, the inductive device 322 can be inductively cooperated 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 the first electrical signal and knows that the manual gate valve 110 is in the closed state. When the manual gate valve 110 is switched from the closed state to the open state, the valve rod 111 moves towards the second trigger 324. When the manual gate valve 110 is in the open state, the valve rod 111 drives the mounting 321 to move to the second position, so that the inductive device 322 is inductively cooperated 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. The control device 200 receives the second electrical signal and knows that the manual gate valve 110 is in the open state. In this way, the opening state or the closed state of the manual gate valve 110 can be checked by using the inspection device, and compared with the traditional manual inspection method, the inspection efficiency can be improved and the labor intensity of troubleshooting can be reduced.

[0046] It should be noted that the specific implementation mode of the control device can be various, including but not limited to computer, mobile phone, smart speaker and the like.

[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 on the storage tank or the ground.

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

[0050] As shown in Figures 2 to 4 The extension direction of the valve rod and the height direction of the support are arranged in the same direction as the Z-axis direction. That is, the mounting moves along the Z-axis direction to switch between the first position and the second position.

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

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

[0053] It can be understood that most of the storage tank volume is relatively large, and the position of the manual gate valve is relatively high. When manually checking, it is necessary to use a ladder or other tools to check the state of the manual gate valve. The labor intensity of checking is large, and the efficiency is low. The detection device of the application can directly detect the opening or closing state of the manual gate valve, improve the checking efficiency, and reduce the labor intensity of checking.

[0054] As shown in Figure 1 some embodiments, the oil storage equipment 10 includes a plurality of storage tanks 100 and is arranged in an oil depot. In this way, when it is necessary to check the safety of the oil depot or to check the state of the manual gate valve 110 of the plurality of storage tanks 100 in the oil depot due to abnormal failure, the detection device 300 can be used to check the state of each manual gate valve 110 and send the detection information of the manual gate valve 110 to the control device 200. The checking personnel can complete the checking of the manual gate valve 110 in time according to the state of the manual gate valve 110 prompted by the control device 200, which can improve the checking efficiency and reduce the labor intensity of checking.

[0055] Among them, the plurality includes two or more.

[0056] As shown in Figure 2 some embodiments, the support 310 includes a first end portion 313 and a second end portion 314 arranged opposite to the first end portion 313, the first mounting portion 311 and the second mounting portion 312 are arranged between the first end portion 313 and the second end portion 314, and the signal processing module 330 is fixedly arranged on the second end portion 314. In this way, the signal processing module 330 is fixedly arranged on the second end portion 314, and then the first end portion 313 is fixedly connected with the storage tank 100, so that the signal processing module 330 can be arranged on the storage tank 100. It is easy to implement and convenient to install.

[0057] In addition, the first mounting portion and the second mounting portion are arranged between the first end portion and the second end portion, so that when the valve rod drives the inductive device to move, the inductive device does not interfere with the signal processing module, and the reliability of the state detection of the manual gate valve is improved.

[0058] It should be noted that the specific implementation mode of the first end portion can be various, and it can be connected with the storage tank.

[0059] As shown in Figure 2As shown, in some embodiments, the signal processing module 330 further comprises a module body 331 and a flexible conductive wire 332 electrically connected with the module body 331, and the flexible conductive wire 332 is electrically connected with the sensing device 322. In this way, the flexible conductive wire 332 is used to realize the electrical connection between the module body 331 and the sensing device 322, thereby improving the reliability of the communication connection between the module body 331 and the sensing device 322. Meanwhile, the flexible conductive wire 332 is deformable and does not interfere with the movement of the sensing device 322.

[0060] Optionally, as shown in FIG. 4, in some embodiments, the flexible conductive wire 332 is provided with a plurality of elastic members 3321. Figures 2 to 4 As shown, in some embodiments, at least a part of the flexible conductive wire 332 is in a spiral shape, so that the flexible conductive wire 332 is retractable in the height direction of the support. In this way, when the sensing device 322 is close to the module body 331, the flexible conductive wire 332 will contract, and the length of the flexible conductive wire 332 in the height direction of the support will become shorter. When the sensing device 322 is away from the module body 331, the flexible conductive wire 332 will be stretched, and the length of the flexible conductive wire 332 in the height direction of the support will become longer. In this way, the flexible conductive wire 332 can be retracted in the height direction of the support, and will not be wound around the sensing device 322 or the valve stem 111, thereby avoiding damage.

[0061] Optionally, as shown in FIG. 4, in some embodiments, the detection device 300 further comprises an elastic member 3321 provided on the flexible conductive wire 332. Figure 2 As shown, in some embodiments, the detection device 300 further comprises a protective cover 340 fixed to the second end portion 314, and the protective cover 340 cooperates with the second end portion 314 to form a protective cavity 301, and the signal processing module 330 is arranged in the protective cavity 301. In this way, the protective cavity 301 can effectively protect the signal processing module 330, thereby improving the protection performance of the detection device 300.

[0062] As shown in FIG. 4, in some embodiments, the protective cover 340 is provided with a gap 341 communicating with the protective cavity 301, and the signal processing module 330 is provided with an electrical first end portion 333 which cooperates with the gap 341 to form an electrical connection port. Figure 2 As shown in FIG. 4, in some embodiments, the signal processing module 330 is provided with a plurality of electrical first end portions 333. Figure 3 As shown in FIG. 4, in some embodiments, the signal processing module 330 is provided with a plurality of electrical first end portions 333.

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

[0064] It should be noted that the specific implementation mode of the electrical first end portion can be various, including a USB connector, a board-to-board connector, etc.

[0065] It should be noted that the connection mode of the mounting member and the valve stem can be various, including but not limited to adhesive fixing, screw fixing, rotary connection, etc. For example, the mounting member is fixedly provided with a screw rod, and the screw rod is screw-fixed with the valve stem.

[0066] Optionally, in some embodiments, the manual gate valve comprises a valve body in communication with the storage tank, a handle rotatably arranged on the valve body, a gate plate arranged in the valve body, and a valve rod connected with the gate plate, the handle is in threaded transmission connection with the valve rod to drive the valve plate to open or close the valve body.

[0067] In some embodiments, the mounting member is in sliding connection with the support member, and the mounting member is in rotational connection with the valve rod. In this way, the valve rod can drive the mounting member to move along the height direction of the support member, but the mounting member will not rotate with the valve rod, so that the wired connection between the sensing device and the signal processing module is more reliable.

[0068] In combination with the aforementioned flexible conductive wire, since the movement of the mounting member is stable, the flexible conductive wire will not be wound around the mounting member.

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

[0070] Optionally, in some embodiments, the support member 310 comprises a sleeve provided with the protection channel 315. It is easy to implement.

[0071] It should be noted that the specific implementation mode of the triggering member and the sensing device 322 can be various, including but not limited to photoelectric detection mode, machine vision detection mode, contact detection mode, magnetic induction detection mode, etc. In some embodiments, the first triggering member 323 comprises a first magnetic ring and is sleeved and fixed with the first mounting portion 311, and the second triggering member 324 comprises a second magnetic ring and is sleeved and fixed with the second mounting portion 312. In this way, the sensing device 322 is in magnetic induction cooperation with the magnetic ring to generate corresponding electrical signals of 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 according to the changes of current, voltage, resistance, etc. generated by the sensing device 322.

[0073] As shown in Figures 2 to 4As shown, in some embodiments, the inductive device 322 includes a first magnetic induction element 3221 and a second magnetic induction element 3222 which is spaced apart from the first magnetic induction element 3221 along the length direction of the valve stem 111. When the manual gate valve 110 is in the closed state, the mounting member 321 is in the first position, the first magnetic induction element 3221 is in magnetic induction cooperation with the first magnetic ring, and a first induction current is generated. In this way, the signal processing module 330 can generate a first electric signal according to the first induction current.

[0074] When the manual gate valve 110 is in the open state, the mounting member 321 is in the second position, the second magnetic induction element 3222 is in magnetic induction cooperation with the second magnetic ring, and a second induction current different from the first induction current is generated. In this way, the signal processing module 330 can generate a second electric signal according to the second induction current.

[0075] The technical features of the above embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0076] The above embodiments only express several implementation manners of the present application, and the description is specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for those skilled in the art, without departing from the inventive concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
