DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1 - Fig.11As shown, the present invention discloses an intelligent remote pressure gauge, including a pressure gauge body 1, a threaded mounting foot 2 is fixedly connected to the bottom surface of which, it should be noted that the threaded mounting foot 2 is used to connect a pressure pipeline, and the pressure pipeline transports high-pressure fluid inside. The high-pressure fluid can be liquid or gas. A connecting channel 21 is opened inside the threaded mounting foot 2, and the connecting channel 21 is directly connected to the cavity inside the pressure pipeline, so that the pressure inside the pressure pipeline directly enters the inside of the pressure gauge body 1 through the connecting 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 range of the pressure gauge body 1. A pressure detection mechanism 5 is arranged inside the pressure gauge body 1. The pressure detection mechanism 5 is used to detect normal pressure. When the high-pressure fluid transported inside the pressure pipeline is under rated pressure, the pressure detection mechanism 5 will directly collect the pressure value of the high-pressure fluid entering the inside of the pressure gauge body 1. The pressure value is the pressure value when the high-pressure fluid inside the pipeline is in 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 transmit the pressure value to the background terminal through the wireless network, so that the background terminal can remotely monitor the operating status of the pressure pipeline in real time. A pressure buffer mechanism 6 is arranged between the pressure gauge body 1 and the threaded mounting foot 2. The pressure buffer mechanism 6 is used to detect abnormal pressure. It should be noted that the pressure buffer mechanism 6 is used to collect the pressure value of the high-pressure fluid inside the pipeline when it is in an 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 large, it will affect the transportation of the pressure pipeline, and the higher pressure will also affect the collection accuracy of the pressure detection mechanism 5. Therefore, when the fluid pressure inside the pressure pipeline is in an abnormal state, the pressure buffer mechanism 6 collects the abnormal pressure of the fluid inside the pressure pipeline, and transmits the abnormal pressure to the control background through the wireless network, so that the control background can obtain the abnormal pressure value in time and accurately, and make corresponding processing measures. The pressure gauge body 1 is loaded with a control module, and the control module collects pressure data through the pressure detection mechanism 5. The pressure buffer 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 buffer mechanism 6 for pressure collection.

[0034] When in use, a wireless network module and a power supply module can be installed on the inner side of the pressure gauge body 1. The pressure detection mechanism 5 and the pressure buffer mechanism 6 both transmit the fluid pressure value inside the pressure pipeline to the background terminal through the wireless network module. The technicians in this field preset the fluid pressure threshold according to the type of pressure pipeline and the internal transport fluid. The pressure detection mechanism 5 can accurately collect the pressure value below the fluid pressure threshold, and 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. The back-end terminal is convenient for the back-end terminal to remotely monitor the operating status of the pressure pipeline in real time. When the fluid pressure value inside the pressure pipeline is greater than the fluid pressure threshold, the pressure buffer mechanism 6 closes the pressure detection mechanism 5 under the action of high pressure and accurately collects the fluid pressure value, and transmits the fluid pressure value to the back-end terminal through the wireless network module, which is convenient for the back-end terminal to obtain the abnormal pressure value in time and accurately, and take corresponding processing 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 ensure 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 pressure gauge.

[0035] Example 2

[0036] A control panel 11 is fixedly connected to the top of the inner cavity of the pressure gauge body 1, a first sleeve 12 is fixedly connected to the center of the pressure gauge body 1, a second sleeve 13 is fixedly connected to one side of the first sleeve 12, and the pointer 4 is installed on the first sleeve 12 through a rotating shaft. It should be noted that a transparent disc needs to be installed on the outer side 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 the scale plate 3 An arc-shaped resistance bar can be set on it, and the end position of the pointer 4 is slidably connected to the arc-shaped resistance bar. When the pointer 4 moves on the scale plate 3, it also indicates that the arc-shaped resistance bar will change. The arc-shaped resistance bar is connected to the power module through a wire, and a resistance sensor is set. The resistance sensor converts the resistance change of the arc-shaped resistance bar 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, and the background terminal converts the electrical signal into the reading value of the scale plate 3, so that the background terminal can remotely monitor the pressure value on the pressure gauge body 1 in real time.

[0037] Example 3

[0038] like Figures 1 to 7As shown, the pressure detection mechanism 5 includes a fixed cylinder 51, one end of the fixed cylinder 51 is fixedly connected to an arc spring tube 52, the end of the arc 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 fan gear 56, the side of the fan gear 56 is meshed with a driving gear 57, the driving gear 57 is fixedly connected to the rotating shaft of the pointer 4, and the fan gear 56 is installed on the first sleeve 12 through the rotating shaft. It should be noted that a connecting groove 511 is opened inside the fixed cylinder 51, and the connecting groove 511 is connected to the connecting channel 21, so the high-pressure fluid in the connecting channel 21 can directly enter the connecting groove 511, and the arc spring tube 52 is connected to the inner end of the connecting groove 511, so when the high-pressure fluid enters the inside of the connecting groove 511, it will also directly enter the arc spring tube 5 2, the arc spring tube 52 will convert the pressure of the high-pressure fluid into elastic potential energy, which will be transmitted to the rotating lever 54 through the connecting seat 53. The rotating lever 54 will drive the fan gear 56 through the connecting card 55 to rotate the fan gear 56. Since the fan gear 56 is meshed with the driving gear 57, the rotating fan 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, so the rotating driving gear 57 will drive the pointer 4 to rotate, so that the pointer 4 will produce a reading on the scale plate 3. Since the elastic potential energy of the arc spring tube 52 is also related to the fluid pressure entering the arc spring tube 52, that is, the greater the pressure value of the fluid pressure, the greater the elastic potential energy of the arc spring tube 52, the corresponding rotation amplitude of the fan gear 56 is also greater, and the corresponding rotation angle of the pointer 4 on the scale plate 3 is also greater, thereby realizing accurate collection of the fluid pressure value.

[0039] It should be noted that if Figure 7 As shown, the sector gear 56 is installed on the second shaft sleeve 13 through a rotating shaft, ensuring that the sector gear 56 can stably rotate with the second shaft sleeve 13 as the center of the circle, and the connecting card 55 between the rotating lever 54 and the sector gear 56 is movably connected, ensuring that the rotating lever 54 can normally drive the sector gear 56 to rotate.

[0040] Example 4

[0041] like Figures 8 to 11As shown, the pressure buffer 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 sealed and connected to a connecting pipe 63, the 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, and a high pressure chamber 66 is provided inside the pressure hydraulic cylinder 61 11. A high-pressure disc 613 is embedded in the inner side of the high-pressure chamber 611. An inflation valve 612 is installed at one end of the high-pressure chamber 611. An external port 614 is installed at the other end of the high-pressure chamber 611. The external port 614 is directly connected to the connecting pipe 63. It should be noted that the high-pressure chamber 611 is pre-filled with high-pressure nitrogen. The pressure value of the high-pressure nitrogen is related to the pressure pipeline. The pressure threshold of the fluid in the pressure pipeline is preferably adjusted, that is, the pressure value of the high-pressure nitrogen is adjusted to the pressure threshold. The nitrogen can ensure the stability of the high-pressure chamber 611.

[0042] The high-pressure disc 613 includes an arcuate surface 6131, and a circular sleeve 6132 is embedded on the side of the arcuate surface 6131. ​​The circular sleeve 6132 fits with the inner wall of the high-pressure chamber 611. The arcuate surface 6131 increases the contact area between the high-pressure disc 613 and the nitrogen inside the high-pressure chamber 611, and at the same time ensures that when the internal fluid of the pressure pipeline undergoes a large pressure change, the arcuate surface 6131 can play a strong buffering role, prevent the high-pressure disc 613 from moving too fast, and improve the stability and safety of the pressure hydraulic cylinder 61.

[0043] The side of the high-pressure disc 613 away from the high-pressure chamber 611 is filled with hydraulic oil, and the specifications of the hydraulic oil are adaptively selected by those skilled in the art according to the specific usage scenario of the smart remote pressure gauge.

[0044] like Figures 1 to 11As shown, the automatic sealing mechanism 66 includes a pressure disc 661, the bottom surface of the pressure disc 661 is fixedly connected with a connecting rod 662, the end of the connecting rod 662 away from the pressure disc 661 is fixedly connected with an adjusting disc 663, the side of the adjusting disc 663 is fixedly connected with a sealing arc piece 664, the surface of the adjusting disc 663 is provided with a fan-shaped connecting groove 665, the inner side of the fixed cylinder 51 is provided with a connecting groove 511, the adjusting disc 663 and the connecting groove 511 fit each other, the side of the adjusting disc 663 is provided with a limiting slide groove 666, the inner wall of the connecting groove 511 is fixedly connected with a limiting slide rail matching the limiting slide groove 666, and the limiting slide groove 666 cooperates with the limiting slide rail to make the adjusting disc 663 stably inside the connecting groove 511 Move, the end of the regulating cylinder 64 away from the automatic sealing mechanism 66 is fixedly connected with a sealing ring 67, a measuring spring 610 is connected between the sealing ring 67 and the pressure disc 661, the outer end of the sealing ring 67 is threadedly connected with a control bolt 69, the side of the sealing ring 67 is fixedly connected with a connecting ring 68, the sealing ring 67 and the connecting ring 68 form a hydraulic chamber, and the connecting pipe 63 is connected to the hydraulic chamber through the regulating 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, and the sealing ring 67, the pressure disc 661 and the fixed cylinder 51 form a sealed chamber to ensure that the hydraulic oil fills the sealed chamber. 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 Pressure threshold, at this time, the pressure of the fluid inside the pressure pipe will act on one side of the pressure disc 661 through the fan-shaped connecting 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 overcome the pressure of the high-pressure nitrogen and move toward the connecting ring 68. In the process of the pressure disc 661 moving toward the connecting ring 68, 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 docking port of the arc spring tube 52 and the connecting groove 511 The arc spring tube 52 is isolated from the fluid, so that the pressure detection mechanism 5 is isolated from the abnormal fluid, which improves the protection effect of the pressure detection mechanism 5, and the pressure disc 661 squeezes 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 chamber 611, and the pressure of the high-pressure nitrogen is increased. When the high-pressure nitrogen is increased to balance with the fluid pressure, the pressure disc 661 will stop moving. A measuring spring 610 is set between the connecting ring 68 and the pressure disc 661. Since the fluid pressure at this time is very large, the elastic force applied by the measuring spring 610 to the pressure disc 661 can be ignored. Two terminals are set in 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 resistance change of the measuring spring 610, and the 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, so that the pressure disc 661 moves to the side away from the sealing ring 67. At this time, the sealing arc piece 664 will be separated from the docking port of the arc spring tube 52 and the connecting groove 511, so that the fluid can re-enter the arc spring tube 52, so that the pressure detection mechanism 5 can operate automatically without manual adjustment, ensuring that the intelligent remote pressure gauge can be used repeatedly in extreme cases without reducing the accuracy, because the pressure detection mechanism 5 is always under the rated pressure to collect the pressure value of the fluid, ensuring that the pressure detection mechanism 5 will not have measurement fatigue.

[0045] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
