Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] As Figure 1 - Figure 11As shown in the figure, the present invention discloses an intelligent remote transmission pressure gauge, which includes a pressure gauge body 1, and a threaded installation foot 2 is fixedly connected to the bottom surface thereof. It should be noted that the threaded installation foot 2 is used to connect a pressure pipeline, and high-pressure fluid is transported inside the pressure pipeline. The high-pressure fluid can be either liquid or gas. A connection channel 21 is provided inside the threaded installation foot 2, and the connection channel 21 is directly communicated with the cavity inside the pressure pipeline. In this way, the pressure inside the pressure pipeline enters the inside of the pressure gauge body 1 directly through the connection channel 21. A scale plate 3 and a pointer 4 are installed on the top surface of the pressure gauge body 1. The scale plate 3 and the pointer 4 are adaptively set by those skilled in the art according to the specific specifications and measuring ranges of the pressure gauge body 1. A pressure detection mechanism 5 is provided inside the pressure gauge body 1, and the pressure detection mechanism 5 is used to detect the normal pressure. When the high-pressure fluid transported inside the pressure pipeline is under the rated pressure, the pressure detection mechanism 5 directly collects the pressure value of the high-pressure fluid entering the inside of the pressure gauge body 1. This pressure value is the pressure value of the high-pressure fluid inside the pipeline under the normal working range, that is, the normal pressure. In other words, the pressure detection mechanism 5 collects the pressure value inside the pipeline when the pressure pipeline is in normal working condition, and transmits this pressure value to the background terminal through a wireless network, so as to facilitate the background terminal to remotely and real-time monitor the operating state of the pressure pipeline. A pressure buffering mechanism 6 is provided between the pressure gauge body 1 and the threaded installation foot 2, and the pressure buffering mechanism 6 is used to detect abnormal pressure. It should be noted that the pressure buffering mechanism 6 is used to collect the pressure value of the high-pressure fluid inside the pipeline under the abnormal working range. That is, when the fluid pressure inside the pressure pipeline is greater than the rated pressure value. In other words, when the fluid pressure inside the pressure pipeline is too high, it will affect the transportation of the pressure pipeline, and the higher pressure will also affect the acquisition accuracy of the pressure detection mechanism 5. Therefore, when the fluid pressure inside the pressure pipeline is in an abnormal state, the pressure buffering mechanism 6 collects the abnormal pressure of the fluid inside the pressure pipeline, and transmits this abnormal pressure to the control background through a wireless network, so as to facilitate the control background to obtain this abnormal pressure value in a timely and accurate manner and take corresponding treatment measures. A control module is installed on the pressure gauge body 1. The control module collects pressure data through the pressure detection mechanism 5, and the pressure buffering mechanism 6 automatically controls the pressure detection mechanism 5 based on the pressure data, so that the pressure detection mechanism 5 automatically switches to the pressure buffering mechanism 6 for pressure acquisition.

[0034] During use, a wireless network module and a power module can be installed inside the pressure gauge body 1. Both the pressure detection mechanism 5 and the pressure buffer mechanism 6 transmit the fluid pressure value inside the pressure pipeline to the background terminal through the wireless network module. Those skilled in the art preset the fluid pressure threshold according to the type of the pressure pipeline and the transported fluid inside. The pressure detection mechanism 5 can accurately collect the pressure value below the fluid pressure threshold, while the pressure buffer mechanism 6 can accurately collect the pressure value exceeding the fluid pressure threshold. When the fluid pressure value inside the pressure pipeline is less than or equal to the fluid pressure threshold, the pressure detection mechanism 5 can accurately collect the fluid pressure value and transmit the fluid pressure value to the background terminal through the wireless network module, facilitating the background terminal to remotely and real-time monitor the operating state of the pressure pipeline. When the fluid pressure value inside the pressure pipeline is greater than the fluid pressure threshold, under the action of high pressure, the pressure buffer mechanism 6 closes the pressure detection mechanism 5 while accurately collecting the fluid pressure value and transmits the fluid pressure value to the background terminal, facilitating the control background to timely and accurately obtain the abnormal pressure value and take corresponding treatment measures to improve safety. The closure of the pressure detection mechanism 5 helps to protect the collection accuracy of the pressure detection mechanism 5 from being affected and ensures the service life of the pressure detection mechanism 5. The segmented collection of the pressure detection mechanism 5 and the pressure buffer mechanism 6 ensures the accuracy of data collection of the intelligent remote transmission pressure gauge.

[0035] Embodiment 2

[0036] A control panel 11 is fixedly connected to the top position of the inner cavity of the pressure gauge body 1. A first bushing 12 is fixedly connected to the central position of the pressure gauge body 1. A second bushing 13 is fixedly connected to one side of the first bushing 12. The pointer 4 is installed on the first bushing 12 through a rotating shaft. It should be noted that a transparent disc needs to be installed on the outside of the pressure gauge body 1 near the pointer 4. The transparent disc is used to protect the scale plate 3 and the pointer 4 inside the pressure gauge body 1, and at the same time ensure that the scale plate 3 and the pointer 4 can be directly observed through the transparent disc, so that the reading of the pointer 4 can be directly read. In addition, it should be noted that an arc-shaped resistance strip can be set on the scale plate 3. The end position of the pointer 4 is slidably connected to the arc-shaped resistance strip. When the pointer 4 moves on the scale plate 3, it also means that the arc-shaped resistance strip will change. Connect the arc-shaped resistance strip to the power module through a wire, and set a resistance sensor. The resistance sensor converts the resistance change of the arc-shaped resistance strip into an electrical signal and transmits the electrical signal to the control panel 11. The control panel 11 transmits the electrical signal to the background terminal through the wireless network module. The background terminal then converts the electrical signal into the reading value of the scale plate 3, so that the background terminal can remotely and real-time monitor the pressure value on the pressure gauge body 1.

[0037] Embodiment 3

[0038] Such as Figures 1 to 7As shown in the figure, the pressure detection mechanism 5 includes a fixed cylinder 51. One end of the fixed cylinder 51 is fixedly connected to an arc-shaped spring tube 52. The end of the arc-shaped spring tube 52 away from the fixed cylinder 51 is fixedly connected to a connecting seat 53. The end of the connecting seat 53 is rotatably connected to a rotating lever 54. The end of the rotating lever 54 away from the connecting seat 53 is rotatably connected to a sector gear 56. The side of the sector gear 56 is engaged with a driving gear 57. The driving gear 57 is fixedly connected to the rotating shaft of the pointer 4. The sector gear 56 is installed on the first bushing 12 through a rotating shaft. It should be noted that a communication groove 511 is opened inside the fixed cylinder 51, and the communication groove 511 is communicated with the connection channel 21. Therefore, the high-pressure fluid in the connection channel 21 can directly enter the inside of the communication groove 511. The arc-shaped spring tube 52 is communicated with the inner end of the communication groove 511. Therefore, when the high-pressure fluid enters the inside of the communication groove 511, it will also directly enter the arc-shaped spring tube 52. The arc-shaped spring tube 52 will convert the pressure of the high-pressure fluid into elastic potential energy. The elastic potential energy will be transmitted to the rotating lever 54 through the connecting seat 53. The rotating lever 54 will drive the sector gear 56 through the connecting clip 55, causing the sector gear 56 to rotate. Since the sector gear 56 is engaged with the driving gear 57, the rotating sector gear 56 will drive the driving gear 57 to rotate. And the driving gear 57 is fixedly connected to the rotating shaft of the pointer 4. Therefore, the rotating driving gear 57 will drive the pointer 4 to rotate, causing the pointer 4 to generate a reading on the scale plate 3. Since the elastic potential energy of the arc-shaped spring tube 52 is also related to the fluid pressure entering the inside of the arc-shaped spring tube 52, that is, the greater the pressure value of the fluid pressure, the greater the elastic potential energy of the arc-shaped spring tube 52, the greater the rotation amplitude of the corresponding sector gear 56, and the greater the angle of rotation of the corresponding pointer 4 on the scale plate 3, thus realizing the accurate acquisition of the fluid pressure value.

[0039] It should be noted that, as Figure 7 shown, the sector gear 56 is installed on the second bushing 13 through a rotating shaft to ensure that the sector gear 56 can rotate stably with the second bushing 13 as the center. The connecting clip 55 between the rotating lever 54 and the sector gear 56 is movably connected to ensure that the rotating lever 54 can drive the sector gear 56 to rotate normally.

[0040] Embodiment 4

[0041] As Figures 8 to 11As shown, the pressure buffering mechanism 6 includes a pressure hydraulic cylinder 61. One end of the pressure hydraulic cylinder 61 is rotatably connected to a mounting plate 62. The mounting plate 62 is fixedly connected to the inner wall of the pressure gauge body 1 by bolts. The other end of the pressure hydraulic cylinder 61 is hermetically connected to a connecting pipe 63. One end of the connecting pipe 63 away from the pressure hydraulic cylinder 61 is fixedly connected to an adjusting cylinder 64. One end of the adjusting cylinder 64 is fixedly connected to a communication port 65. The adjusting cylinder 64 is connected to an automatic sealing mechanism 66 through the communication port 65. A high-pressure gas chamber 611 is provided inside the pressure hydraulic cylinder 61. A high-pressure disc 613 is fitted inside the high-pressure gas chamber 611. An inflation valve 612 is installed at one end of the high-pressure gas chamber 611. An external connection port 614 is installed at the other end of the high-pressure gas chamber 611. The external connection port 614 is directly connected to the connecting pipe 63. It should be noted that high-pressure nitrogen is pre-filled inside the high-pressure gas chamber 611. The pressure value of the high-pressure nitrogen is related to the pressure pipeline, preferably the pressure threshold value of the fluid inside the pressure pipeline, that is, the pressure value of the high-pressure nitrogen is adjusted to the pressure threshold value. Nitrogen can ensure the stability inside the high-pressure gas chamber 611.

[0042] The high-pressure disc 613 includes an arc surface 6131. A circular ring sliding sleeve 6132 is nested on the side surface of the arc surface 6131. The circular ring sliding sleeve 6132 fits with the inner wall of the high-pressure gas chamber 611. The arc surface 6131 increases the contact area between the high-pressure disc 613 and the nitrogen inside the high-pressure gas chamber 611. At the same time, it ensures that when there is a large pressure change in the fluid inside the pressure pipeline, the arc surface 6131 can play a strong buffering role, preventing the high-pressure disc 613 from moving too fast, and improving the stability and safety of the pressure hydraulic cylinder 61.

[0043] Hydraulic oil is filled on the side of the high-pressure disc 613 away from the high-pressure gas chamber 611. The specification of the hydraulic oil is adaptively selected by those skilled in the art according to the specific use scenario of the intelligent remote transmission pressure gauge.

[0044] As Figures 1 to 11As shown, the automatic sealing mechanism 66 includes a pressure disc 661. A connecting rod 662 is fixedly connected to the bottom surface of the pressure disc 661. One end of the connecting rod 662 away from the pressure disc 661 is fixedly connected to an adjusting disc 663. A sealing arc piece 664 is fixedly connected to the side surface of the adjusting disc 663. A fan-shaped communication groove 665 is formed on the surface of the adjusting disc 663. A communication groove 511 is formed inside the fixed cylinder 51. The adjusting disc 663 is fitted with the communication groove 511. A limiting sliding groove 666 is formed on the side surface of the adjusting disc 663. A limiting sliding rail matching the limiting sliding groove 666 is fixedly connected to the inner wall of the communication groove 511. Through the cooperation of the limiting sliding groove 666 and the limiting sliding rail, the adjusting disc 663 can stably move inside the communication groove 511. One end of the adjusting cylinder 64 away from the automatic sealing mechanism 66 is fixedly connected to a sealing ring 67. A measuring spring 610 is connected between the sealing ring 67 and the pressure disc 661. One end of the outer side of the sealing ring 67 is threadedly connected with a control bolt 69. A communication ring 68 is fixedly connected to the side surface of the sealing ring 67. The sealing ring 67 and the communication ring 68 form a hydraulic cavity. The connecting pipe 63 is communicated with the hydraulic cavity through the adjusting cylinder 64. It should be noted that the hydraulic oil in the pressure hydraulic cylinder 61 enters the inner side of the sealing ring 67 through the connecting pipe 63. The sealing ring 67, the pressure disc 661 and the fixed cylinder 51 form a sealed cavity to ensure that the hydraulic oil fills the sealed cavity. When the fluid pressure inside the pressure pipeline is in an abnormal state, that is, the fluid pressure inside the pressure pipeline is greater than the pressure threshold, at this time, the pressure of the fluid inside the pressure pipeline will act on one side of the pressure disc 661 through the fan-shaped communication groove 665. Since the pressure of the hydraulic oil filled on the other side of the pressure disc 661 is equal to the pressure of the high-pressure nitrogen, that is, the pressure threshold, the pressure exerted by the fluid on the pressure disc 661 is greater than the pressure of the hydraulic oil on the pressure disc 661. The pressure disc 661 will move towards the communication ring 68 side against the pressure of the high-pressure nitrogen. During the process of the pressure disc 661 moving towards the communication ring 68 side, the pressure disc 661 will drive the adjusting disc 663 through the connecting rod 662, and the adjusting disc 663 will drive the sealing arc piece 664. The moving sealing arc piece 664 will seal the butt joint port of the arc-shaped spring tube 52 and the communication groove 511, that is, isolate the arc-shaped spring tube 52 from the fluid. In this way, the pressure detection mechanism 5 will be isolated from the abnormal fluid, improving the protection effect on the pressure detection mechanism 5. And the pressure disc 661 will squeeze the high-pressure disc 613 through the hydraulic oil, so that the high-pressure disc 613 squeezes the high-pressure nitrogen inside the high-pressure gas cavity 611, increasing the pressure of the high-pressure nitrogen. When the high-pressure nitrogen increases to balance with the fluid pressure, the pressure disc 661 will stop moving. A measuring spring 610 is arranged between the communication ring 68 and the pressure disc 661. Since the fluid pressure at this time is very high, the elastic force exerted by this measuring spring 610 on the pressure disc 661 can be ignored. Two terminals are arranged inside the control bolt 69 for collecting the resistance change of the measuring spring 610.The pressure value of the fluid at this time is obtained according to the change in the resistance of the measuring spring 610, and this pressure value is transmitted to the background terminal through the wireless network module. When the pressure value of the fluid drops below the pressure threshold, the pressure disc 661 will be squeezed by the high-pressure nitrogen gas again, causing the pressure disc 661 to move away from the sealing ring 67. At this time, the sealing arc piece 664 will disengage from the docking port of the arc spring tube 52 and the communication groove 511, so that the fluid can re-enter the arc spring tube 52, enabling the pressure detection mechanism 5 to operate automatically without manual adjustment, ensuring that the intelligent remote pressure gauge can be repeatedly used in extreme situations without reducing the accuracy, because the pressure detection mechanism 5 always collects the pressure value of the fluid under the rated pressure, ensuring that the pressure detection mechanism 5 will not undergo measurement fatigue.

[0045] The above has described a specific embodiment of the present invention in detail, but the described content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
