Description

Technical Field

[0001] This utility model relates to the field of natural gas storage tank technology, specifically to a natural gas storage tank leakage detection device. Background Technology

[0002] A natural gas storage tank is a container used to store natural gas, typically in liquid or compressed gas form, to meet industrial, commercial, and residential needs. Since natural gas is a gas at normal temperature and pressure, it usually needs to be compressed or cooled into a liquid state for easier transportation, storage, and use.

[0003] A natural gas storage tank according to the formula (publication number: CN 213394607U): includes a storage tank, a restraint belt, a guardrail, a base, and a fixing rod. The side of the storage tank is interference-fitted with the restraint belt, and the side of the guardrail is connected to the side pipe of the storage tank.

[0004] In the aforementioned application, the cooperation between the storage tank and the fixed rod assembly makes it difficult to detect leaks in the storage tank during use, resulting in an inability to react quickly when a leak occurs, which could lead to fire or explosion accidents. Therefore, we propose a natural gas storage tank leak detection device. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a natural gas storage tank leakage detection device, which solves the technical problem that the prior art cannot detect leaks in storage tanks.

[0006] According to one aspect, at least one embodiment of the present invention provides a natural gas storage tank leakage detection device, comprising: a mounting plate, a support plate fixedly connected to the top of the mounting plate, a storage tank detachably connected to the top of the support plate, a gas outlet pipe fixedly passing through the top of the storage tank, and a leakage detection mechanism provided at the connection of the gas outlet pipe;

[0007] The leak detection mechanism includes a detection box, which is fixedly connected to the circumferential surface of the vent pipe. The detection box has a detection chamber inside, and an expansion body is installed inside the detection chamber. A push plate is fixedly connected to the side of the expansion body. A support shaft is rotatably connected inside the detection box. A force-bearing plate is fixedly connected to the circumferential surface of the support shaft. A support connecting rod is fixedly connected to the circumferential surface of the support shaft. A baffle is rotatably connected to the end of the support connecting rod away from the support shaft. The side of the baffle penetrates and slides through the circumferential surface of the vent pipe.

[0008] For example, in at least one embodiment of the present invention, a natural gas storage tank leakage detection device is provided, which further includes: a start button is provided inside the detection box, and an alarm light is provided on the side of the detection box, the purpose of which is to ensure that the leaking gas can be promptly alerted to the staff.

[0009] A reset spring is fixedly connected inside the testing box. The end of the reset spring away from the inside of the testing box is fixedly connected to the trigger end of the start button. The purpose of this is to ensure that the start button can automatically reset and reduce manual intervention.

[0010] The inside of the testing box is fixedly connected to a torsion spring. The end of the torsion spring away from the inside of the testing box is fixedly connected to the circumferential surface of the support shaft. The purpose of this is to ensure that the support shaft can automatically reset and reduce manual intervention.

[0011] The side of the force plate is located on the displacement trajectory of the push plate, and the trigger end of the start button is located on the displacement trajectory of the push plate. The purpose is to ensure that the movement of the push plate can push the force plate and to ensure that the movement of the push plate can squeeze the trigger end of the start button.

[0012] According to another aspect, at least one embodiment of the present invention also provides a natural gas storage tank leakage detection device, comprising: an installation mechanism provided on the top of the mounting plate, the installation mechanism including a fixing plate, the fixing plate being fixedly connected to the top of the mounting plate, a motor being fixedly connected to the side of the fixing plate, a double-stroke threaded rod being fixedly connected to the output end of the motor, a threaded sleeve being threadedly connected to the circumferential surface of the double-stroke threaded rod, a connecting rod being fixedly connected to the top of the threaded sleeve, and a clamping arc plate being fixedly connected to the end of the connecting rod away from the top of the threaded sleeve, the purpose of which is to prevent the storage tank from shaking when it is impacted and to prevent the tank from tipping over.

[0013] For example, in a natural gas storage tank leakage detection device provided in at least one embodiment of the present invention, a shock-absorbing spring is fixedly connected inside the clamping arc plate, and a shock-absorbing plate is fixedly connected to one end of the shock-absorbing spring away from the inside of the clamping arc plate, the purpose of which is to eliminate the vibration force generated by the storage tank.

[0014] A limiting plate is fixedly connected to the top of the mounting plate. The side of the limiting plate passes through and is rotatably connected to the circumferential surface of the double-stroke threaded rod. Its purpose is to limit the displacement distance of the threaded sleeve.

[0015] The limiting plate has a limiting shaft fixedly connected to its side. The circumferential surface of the limiting shaft passes through and slides through the side of the threaded sleeve. The purpose of this is to prevent the threaded sleeve from rotating during movement.

[0016] The number of threaded sleeves, shock-absorbing springs, and limiting shafts is set to two, and they are symmetrical to each other along the vertical central axis of the mounting plate. The initial state of the shock-absorbing springs is a relaxed state. The purpose is to absorb and buffer external vibrations or impacts through the elastic action of the springs during equipment operation, reduce damage to the equipment, thereby protecting the threaded sleeves and limiting shafts and improving the stability and service life of the equipment.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] In this invention, through the coordinated operation of components such as the detection box, baffle, and alarm light in the leak detection mechanism, when a leak occurs at the outlet pipe connection, the leaking gas enters the detection chamber, causing an increase in pressure. This causes the expansion body to expand and move the push plate, pushing the support shaft of the force plate to rotate, thereby driving the baffle to close the outlet pipe. The push plate continues to press the start button, triggering the alarm light to alert personnel for maintenance. After maintenance is completed, the expansion body returns to its initial state, the start button resets, the alarm light turns off, the support shaft resets, and the baffle reopens the outlet pipe, ensuring normal equipment operation. This design achieves the effect of leak detection for storage tanks, enabling a rapid response in the event of a leak, thereby effectively preventing fires or explosions.

[0019] In this invention, through the coordinated operation of components such as the motor, clamping arc plate, and shock-absorbing springs in the installation mechanism, when the storage tank is placed on the support plate, the motor is activated to drive the double-stroke threaded rod to rotate, causing the threaded sleeve to move linearly. This movement, in turn, drives the clamping arc plate to fix the storage tank via the connecting rod. If the storage tank is impacted, the clamping arc plate provides stable support. Simultaneously, the shock-absorbing springs and shock-absorbing plate elastically buffer and release vibrations, reducing the impact force. This design achieves the effect of stable installation of the storage tank, ensuring its stability and safety, and preventing vibration damage. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, it illustrates a natural gas storage tank leak detection device according to an embodiment of the present invention, including: a mounting plate 1, a support plate 2 fixedly connected to the top of the mounting plate 1, a storage tank 3 detachably connected to the top of the support plate 2, a gas outlet pipe 4 fixedly passing through the top of the storage tank 3, and a leak detection mechanism 5 provided at the connection of the gas outlet pipe 4.

[0034] The leak detection mechanism 5 includes a detection box 51, which is fixedly connected to the circumferential surface of the vent pipe 4. The detection box 51 has a detection chamber 52 inside, and an expansion body 53 is installed inside the detection chamber 52. A push plate 54 is fixedly connected to the side of the expansion body 53. A support shaft 55 is rotatably connected inside the detection box 51. A force plate 56 is fixedly connected to the circumferential surface of the support shaft 55. A support connecting rod 57 is fixedly connected to the circumferential surface of the support shaft 55. A baffle 58 is rotatably connected to the end of the support connecting rod 57 away from the support shaft 55. The side of the baffle 58 penetrates and slides through the circumferential surface of the vent pipe 4.

[0035] In some examples, the detection box 51 is equipped with an activation button 59 inside and an alarm light 510 on the side of the detection box 51, the purpose of which is to ensure that the leaking gas can be promptly alerted to the staff.

[0036] A reset spring 511 is fixedly connected inside the detection box 51. The end of the reset spring 511 away from the inside of the detection box 51 is fixedly connected to the trigger end of the start button 59. The purpose is to ensure that the start button 59 can be automatically reset, reducing manual intervention.

[0037] A torsion spring 512 is fixedly connected inside the detection box 51. One end of the torsion spring 512 away from the inside of the detection box 51 is fixedly connected to the circumferential surface of the support shaft 55. The purpose is to ensure that the support shaft 55 can automatically reset and reduce manual intervention.

[0038] The side of the force plate 56 is located on the displacement trajectory of the push plate 54, and the trigger end of the start button 59 is located on the displacement trajectory of the push plate 54. The purpose is to ensure that the movement of the push plate 54 can push the force plate 56 and to ensure that the movement of the push plate 54 can squeeze the trigger end of the start button 59.

[0039] For example, such as Figures 1-5 As shown, during normal use, when a leak occurs at the connection of the vent pipe 4, the leaked gas enters the detection chamber 52. At this time, the internal pressure of the detection chamber 52 increases, causing the expansion body 53 to expand. During the expansion process, the expansion body 53 drives the push plate 54 to move. The movement of the push plate 54 pushes the force plate 56, which in turn drives the support shaft 55 to rotate. The rotation of the support shaft 55, through the support connecting rod 57, pushes the baffle 58, causing the baffle 58 to coincide with the inner diameter of the vent pipe 4. The air outlet pipe 4 is closed, causing it to stop working. At the same time, the push plate 54 continues to move, pressing the trigger end of the start button 59, causing the alarm light 510 to sound an alarm and promptly reminding the staff to carry out maintenance. After the maintenance of the connection of the air outlet pipe 4 is completed, the expansion body 53 returns to its initial state, and the start button 59 is reset by the return spring 511, turning off the alarm light 510. At the same time, the support shaft 55 is reset by the elasticity of the torsion spring 512, which in turn causes the baffle 58 to reset and open the air outlet pipe 4.

[0040] like Figures 1-5 As shown, this invention illustrates a natural gas storage tank leak detection device according to another embodiment of the present invention, comprising: a mounting mechanism 6 provided on the top of a mounting plate 1, the mounting mechanism 6 including a fixing plate 61, the fixing plate 61 being fixedly connected to the top of the mounting plate 1, a motor 62 being fixedly connected to the side of the fixing plate 61, a double-stroke threaded rod 63 being fixedly connected to the output end of the motor 62, a threaded sleeve 64 being threadedly connected to the circumferential surface of the double-stroke threaded rod 63, a connecting rod 65 being fixedly connected to the top of the threaded sleeve 64, and a clamping arc plate 66 being fixedly connected to the end of the connecting rod 65 away from the top of the threaded sleeve 64, the purpose of which is to prevent the storage tank 3 from shaking when impacted and to prevent the tank from tipping over.

[0041] In some examples, a damping spring 67 is fixedly connected inside the clamping arc plate 66, and a damping plate 68 is fixedly connected to one end of the damping spring 67 away from the inside of the clamping arc plate 66, the purpose of which is to eliminate the vibration force generated by the storage tank 3.

[0042] A limiting plate 69 is fixedly connected to the top of the mounting plate 1. The side of the limiting plate 69 passes through and is rotatably connected to the circumferential surface of the double-stroke threaded rod 63. Its purpose is to limit the displacement distance of the threaded sleeve 64.

[0043] A limiting shaft 610 is fixedly connected to the side of the limiting plate 69. The circumferential surface of the limiting shaft 610 penetrates and slides through the side of the threaded sleeve 64. The purpose of this is to prevent the threaded sleeve 64 from rotating during movement.

[0044] There are two threaded sleeves 64, shock-absorbing springs 67 and limiting shafts 610, which are symmetrical to each other along the vertical central axis of the mounting plate 1. The initial state of the shock-absorbing springs 67 is relaxed. Its purpose is to absorb and buffer external vibrations or impacts through the elastic action of the springs during equipment operation, reduce damage to the equipment, thereby protecting the threaded sleeves 64 and limiting shafts 610, and improving the stability and service life of the equipment.

[0045] For example, such as Figures 1-5 As shown, when the storage tank 3 is installed and placed on the support plate 2, the operator can start the motor 62. The output end of the motor 62 starts to rotate, which in turn drives the double-stroke threaded rod 63 to rotate. The double-stroke threaded rod 63 drives the threaded sleeve 64 to move linearly through the limiting shaft 610. The movement of the threaded sleeve 64 drives the clamping arc plate 66 to move through the connecting rod 65. During the movement, the clamping arc plate 66 firmly clamps one end of the storage tank 3 to ensure its stable fixation. When the storage tank 3 is impacted or shaken during use, the stable support of the clamping arc plate 66 can effectively resist external forces and prevent the tank from shaking excessively. At the same time, the shock-absorbing spring 67 and the shock-absorbing plate 68 can release the energy of external vibration through elasticity and buffering, further reducing the impact of the impact force on the storage tank 3, thereby effectively preventing the storage tank 3 from being vibrated or damaged, and ensuring its stability and safety.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
