Description

Technical Field

[0001] This utility model relates to the technical field of pressure detection, specifically to a pipeline pressure detection device. Background Technology

[0002] In narrow, elongated tunnel environments such as mines, tunnels, and underground utility tunnels, various pipeline systems are typically required to transport different media to meet production and safety needs, including ventilation, drainage, and gas supply. Because these tunnels are often hundreds of meters or even kilometers long, and the geological conditions along the route are complex, space is limited, and the environment is harsh (e.g., high humidity, dust, vibration, insufficient lighting), effective monitoring of the internal pressure of the pipelines is essential to ensure the safe and stable operation of the pipeline system and to promptly detect abnormal conditions such as blockages, leaks, overpressure, or underpressure.

[0003] Currently, the commonly used technical solution is to install mechanical pressure gauges (i.e., pressure indicators with odometers) at intervals along the pipeline. Typically, one set is installed at regular intervals (e.g., 50 meters, 100 meters, or according to key nodes in the pipeline network) to display real-time pressure values ​​within the pipeline. Monitoring primarily relies on manual inspection: staff must periodically carry a logbook, traveling along the pipeline to each pressure monitoring point, visually reading the odometer readings and manually recording them as a basis for operation and management. However, this traditional monitoring method has several significant drawbacks: 1. High labor intensity and low efficiency: The tunnel environment is narrow and complex, the inspection route is long and inconvenient to pass through. Staff need to frequently travel back and forth between multiple monitoring points and take readings under dim light and poor visibility conditions. The work intensity is high, time-consuming and labor-intensive, which seriously affects the inspection efficiency.

[0004] 2. Data accuracy is difficult to guarantee: Due to poor on-site lighting conditions, the fine scale of the instruments is prone to misreading, omissions, or recording errors; at the same time, manual readings are subject to subjective judgment errors, making it difficult to ensure the objectivity and consistency of the data.

[0005] Therefore, existing technologies still need further development. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a pipeline pressure detection device to solve the technical problems of low pipeline pressure monitoring efficiency and difficulty in ensuring data accuracy caused by relying on manual reading of mechanical pressure gauges in the prior art.

[0007] To achieve the above-mentioned technical objectives, according to one aspect of this utility model: a pipeline pressure detection device is provided, comprising: a pressure detection component for connection to a connection port on a pipeline, the pressure detection component having a first installation space and a first guide channel connected thereto, the first installation space being located above the first guide channel, a detection element of the pressure detection component being installed in the first installation space, and the first guide channel being connected to a flow channel in the pipeline through the connection port; a control component electrically connected to the detection element, the control component being used to control the action of the detection element and to receive and process pressure signals detected by the detection element in the pipeline to obtain pressure data; and a display component electrically connected to the control component, the display component being used to receive and display the pressure data transmitted by the control component and to send a trigger signal to the control component, the control component controlling the detection element to perform detection according to the trigger signal.

[0012] Furthermore, the pipeline pressure detection device also includes: a housing, on which an observation window and a second installation space are provided, a control component and a display component are disposed in the second installation space, and at least a portion of the display component is disposed opposite to the observation window; the pressure detection component also includes: a protective sleeve, in which a first installation space is provided, and the housing is disposed at the top of the protective sleeve; a connector, in which a first guide channel is provided, one end of the connector being connected to the protective sleeve, and the other end of the connector being for connecting to a connection port on the pipeline; so that the medium in the pipeline is conducted to the detection end of the detection component through the connection port and the first guide channel.

[0013] Furthermore, the protective sleeve includes: a sleeve body, the top end of which is connected to the housing, and an installation cavity provided inside the sleeve body, with a portion of the detection element disposed within the installation cavity; a limiting seat located at the bottom of the sleeve body, the limiting seat having an insertion part and a limiting part connected in sequence, the insertion part being inserted into the installation cavity to support the detection element; the limiting part being located at the bottom end of the sleeve body and abutting against the protective sleeve; the insertion part and the limiting part respectively having a first connecting channel and a second connecting channel, the first connecting channel being connected to the installation cavity and the second connecting channel respectively, and the detection end of the detection element being located within the first connecting channel; wherein, the connector is located at the bottom of the limiting seat, and the connector is detachably connected to the limiting seat.

[0015] Furthermore, the pipeline pressure detection device also includes: a dustproof component, the dustproof part of which is used to be inserted into the first guide channel to block the first guide channel; and / or, an energy storage component, which is used to be electrically connected to the control component and to provide electrical energy.

[0016] Furthermore, the pipeline pressure testing device also includes: a mounting bracket, which is mounted on the housing and located on the side of the housing away from the observation window; the mounting bracket is used to engage with the mounting mating part to fix the pipeline pressure testing device.

[0017] Beneficial effects: The pipeline pressure detection device provided by this utility model, using its technical solution, includes: a pressure detection component, a control component, and a display component. The pressure detection component has a first installation space and a first guide channel that are connected to each other. Both the first installation space and the first guide channel extend along a preset direction, with the first installation space located above the first guide channel. The detection element of the pressure detection component is installed within the first installation space, and the detection end of the detection element faces the direction of the first guide channel. The first guide channel is connected to a flow channel within the pipeline via a connection port, allowing the medium within the pipeline to be transmitted through the connection port and the first guide channel to the detection end of the detection element, thereby detecting the pressure within the pipeline. The control component is electrically connected to the detection element of the pressure detection component. The pressure signal detected by the detection element is transmitted to the control component, which receives and processes the pressure signal detected by the detection element within the pipeline to obtain pressure data. Simultaneously, the control component also controls the action of the detection element, i.e., it controls the detection element to be in a working state or a standby state. The display unit is electrically connected to the control unit. The control unit transmits the processed pressure data to the display unit, which then displays the pressure data so that operators can directly read the pressure value of the pipeline at their monitoring point. Simultaneously, the display unit also sends a trigger signal to the control unit. The control unit, based on the trigger signal, controls the detection element to enter a working state, causing it to begin detecting the pipeline pressure.

[0018] Therefore, by configuring the pressure detection component with a first mounting space and a first guide channel that are connected vertically, and with the first mounting space located above the first guide channel, and the detection component installed in the upper space with its detection end facing downwards and aligned with the first guide channel, a vertical layout of "sensor on top, pressure guide below" is achieved. This structure effectively avoids direct impact or long-term immersion of the detection component by the medium, especially liquids, reducing the risk of damage to the detection component and improving sealing performance and service life. Furthermore, the first guide channel is connected to the internal flow channel of the pipeline through a connection port, allowing the medium pressure to be stably and undamagedly transmitted to the detection end of the detection component via the connection port and the first guide channel, ensuring that the pressure signal accurately reflects the actual state of the pipeline and improving detection accuracy and response speed. Simultaneously, the control component is electrically connected to the detection component, capable of receiving and processing pressure signals to acquire digital pressure data; it also controls the working status of the detection component (working / standby), achieving intelligent operation management. Combined with the display component, pressure data can be displayed in real time, eliminating the need for manual reading of the mechanical gauge scale, significantly improving monitoring efficiency and data readability, and effectively ensuring data accuracy. Furthermore, the control unit can keep the detection device in standby mode during non-monitoring periods, significantly reducing overall power consumption and enabling long-term stable operation. This is particularly suitable for long-distance tunnel environments such as mines, tunnels, and underground utility tunnels where power supply is difficult and inspection is inconvenient. In addition, the display unit not only displays pressure data but also sends trigger signals to the control unit, which then initiates the detection process in response. Users can achieve "on-demand detection" through simple operation, avoiding energy waste caused by long-term equipment operation and improving operational flexibility. This utility model's pipeline pressure detection device effectively solves the technical problems of low efficiency and difficulty in ensuring data accuracy in pipeline pressure monitoring caused by relying on manual reading of mechanical pressure gauges in existing technologies.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] Please see Figures 1 to 3 According to an embodiment of the present invention, a pipeline pressure detection device is provided, comprising: a pressure detection component 1, a control component 2, and a display component 3. The pressure detection component 1 is used to connect to a connection port on a pipeline. The pressure detection component 1 has a first installation space 10 and a first guide channel 11 connected to each other. The first installation space 10 is located above the first guide channel 11. The detection element 12 of the pressure detection component 1 is installed in the first installation space 10. The first guide channel 11 is connected to a flow channel in the pipeline through the connection port. The control component 2 is electrically connected to the detection element 12. The control component 2 is used to control the operation of the detection element 12 and to receive and process the pressure signal in the pipeline detected by the detection element 12 to obtain pressure data. The display component 3 is electrically connected to the control component 2. The display component 3 is used to receive and display the pressure data transmitted by the control component 2 and to send a trigger signal to the control component 2. The control component 2 controls the detection element 12 to perform detection according to the trigger signal.

[0023] The pipeline pressure detection device provided by this utility model includes: a pressure detection component 1, a control component 2, and a display component 3. The pressure detection component 1 has a first installation space 10 and a first guide channel 11 that are connected to each other. Both the first installation space 10 and the first guide channel 11 extend along a preset direction, and the first installation space 10 is located above the first guide channel 11. The detection element 12 of the pressure detection component 1 is installed in the first installation space 10, and the detection end of the detection element 12 is set towards the first guide channel 11. The first guide channel 11 is connected to the flow channel in the pipeline through a connection port on the pipeline, so that the medium in the pipeline can be transmitted to the detection end of the detection element 12 through the connection port and the first guide channel 11, and the pressure in the pipeline can be detected through the detection end of the detection element 12. The control component 2 is electrically connected to the detection element 12 of the pressure detection component 1. The pressure signal detected by the detection element 12 is transmitted to the control component 2. The control component 2 is used to receive and process the pressure signal in the pipeline detected by the detection element 12, thereby obtaining pressure data. Meanwhile, control component 2 is also used to control the operation of detection element 12, that is, control component 2 controls detection element 12 to be in working state or standby state. Display component 3 is electrically connected to control component 2. Control component 2 transmits processed pressure data to display component 3, which displays the pressure data so that operators can directly read the pressure value of the pipeline at the monitoring point. At the same time, display component 3 is also used to send a trigger signal to control component 2, which controls detection element 12 to perform detection according to the trigger signal (that is, control component 2 controls detection element 12 to be in working state according to the trigger signal so that detection element 12 starts to detect pipeline pressure).

[0024] Therefore, by configuring the pressure detection component 1 with a first mounting space 10 and a first guide channel 11 connected vertically, with the first mounting space 10 located above the first guide channel 11, and the detection element 12 installed in the upper space with its detection end facing downwards and aligned with the first guide channel 11, a vertical layout of "sensor on top, pressure guide below" is achieved. This structure effectively avoids direct impact or long-term immersion of the detection element 12 by the medium (especially liquid), reducing the risk of damage to the detection element 12 and improving sealing performance and service life. Furthermore, the first guide channel 11 is connected to the internal flow channel of the pipeline through a connection port on the pipeline, allowing the medium pressure to be stably and undamagedly transmitted to the detection end of the detection element 12 via the connection port and the first guide channel 11, ensuring that the pressure signal truly reflects the actual state of the pipeline and improving detection accuracy and response speed. At the same time, the control component 2 is electrically connected to the detection element 12, capable of receiving and processing pressure signals to acquire digital pressure data; it also controls the working state (working / standby) of the detection element 12, realizing intelligent operation management. Combined with display component 3, pressure data can be displayed in real time, eliminating the need for manual reading of the mechanical gauge scale, significantly improving monitoring efficiency and data readability, and effectively ensuring data accuracy. Furthermore, control component 2 can keep the detection element 12 in standby mode during non-monitoring periods, greatly reducing overall power consumption and enabling long-term stable operation. This is particularly suitable for long-distance tunnel environments such as mines, tunnels, and underground utility tunnels where power supply is difficult and inspection is inconvenient. In addition to displaying pressure data, display component 3 can also send trigger signals to control component 2, which then initiates the detection process. Users can achieve "on-demand detection" through simple operation, avoiding energy waste caused by long-term equipment operation and improving usage flexibility. This utility model's pipeline pressure detection device effectively solves the technical problems of low pipeline pressure monitoring efficiency and difficulty in ensuring data accuracy caused by relying on manual reading of mechanical pressure gauges in existing technologies.

[0025] Optionally, the detection element 12 is a pressure sensor.

[0026] Optionally, the end of the first installation space 10 away from the first guide channel 11 is sealed with the detection element 12 to prevent pipeline medium (especially gas) from leaking into the first installation space 10.

[0027] Specifically, such as Figure 1 and Figure 2As shown, the pipeline pressure detection device further includes: a housing 4, which is disposed on top of the pressure detection component 1. The housing 4 has an observation window 41 and a second mounting space 42. The control component 2 and the display component 3 are disposed within the second mounting space 42, and at least a portion of the display component 3 is disposed opposite to the observation window 41. The display component 3 includes: a display screen 31 and a photosensitive trigger. The display screen 31 is electrically connected to the control component 2 and is used to receive and display pressure data transmitted by the control component 2. The display screen 31 is located within the display area of ​​the observation window 41. The photosensitive trigger is located within the display area of ​​the observation window 41 and is used to detect external light intensity. The photosensitive trigger is electrically connected to the control component 2 so that when the external light intensity detected by the photosensitive trigger is greater than or equal to a preset value, the photosensitive trigger sends a trigger signal to the control component 2.

[0028] With the above-described structure, the housing 4 is positioned on top of the pressure detection component 1, forming an independent second installation space 42 to accommodate the control component 2 and the display component 3, achieving centralized sealed protection for the electronic components. This structure effectively isolates external dust, moisture, and mechanical damage, improving the reliability and service life of the device in harsh industrial environments such as mines and tunnels. Furthermore, the housing 4 is equipped with an observation window 41, with at least a portion of the display component 3 (such as a display screen) positioned opposite the observation window 41, allowing pressure data to be clearly seen through the window. Operators can directly read real-time pressure values ​​without disassembling the equipment, significantly improving on-site inspection efficiency and operational convenience. Simultaneously, the display component 3 includes a photosensitive trigger, which is located within the display area of ​​the observation window 41, along with the display screen 31. When the external light intensity reaches a preset value, the photosensitive trigger automatically sends a trigger signal to the control component 2, which then initiates the detection process. This design achieves an intelligent interactive mode of "light-awakening and automatic detection," avoiding frequent button operations, and is particularly suitable for dark, humid, or high-dust environments. In addition, the photosensitive triggering mechanism is based on changes in ambient light, which is highly directional, has strong resistance to electromagnetic interference, and is less prone to false triggering; and it does not require exposed physical buttons, reducing the risk of water leakage and electric shock caused by poor button sealing, further improving the inherent safety level of the device.

[0029] Furthermore, the housing 4 has a mounting hole communicating with the second mounting space 42, and an observation window 41 is provided on the mounting hole to seal the mounting hole and allow external observation of the display content of the display component 3. The observation window 41 is made of transparent material to ensure good light transmission and mechanical strength.

[0030] Alternatively, the viewing window 41 may be made of glass, polycarbonate (PC) or acrylic (PMMA) material.

[0031] Optionally, to ensure airtightness, a sealing element is provided between the mounting hole and the observation window 41 to achieve a sealed isolation and prevent external media from entering the housing.

[0032] Furthermore, the second installation space 42 is a sealed space, which effectively prevents external moisture, dust and corrosive gases from entering the housing, avoiding short circuits, signal interference or functional failures of control components and display components due to moisture, dust accumulation or chemical corrosion, and improving the reliability and service life of the device in harsh industrial environments such as humid, high dust and strong corrosion.

[0033] Furthermore, one end of the first wire is connected to the detection element 12, and the other end of the first wire passes through the first mounting space 10 and the second mounting space 42 in sequence and is connected to the control element 2.

[0034] Furthermore, the photosensitive trigger is disposed on the display screen 31, or the photosensitive trigger is located on one side of the display screen 31. When the external light intensity detected by the photosensitive trigger is greater than or equal to a preset value, the photosensitive trigger sends a trigger signal to the control component 2, and the control component 2 controls the display screen 31 to start.

[0035] With the above-described structure, the photosensitive trigger is positioned on or to the side of the display screen 31, enabling real-time sensing of changes in external light. When an operator shines a flashlight or mobile phone flashlight into the observation window 41, the photosensitive trigger detects that the light intensity has reached a preset value and immediately sends a trigger signal. The control component 2 then wakes up the display screen 31 and displays the pressure data in real time based on the pressure data acquired by the control component 2. This design eliminates the need for physical buttons, avoiding usability issues caused by button malfunctions in humid or dusty environments, significantly improving the convenience and reliability of human-computer interaction. Furthermore, the photosensitive trigger and the display screen 31 are both located within the display area of ​​the observation window 41, making full use of the internal space of the housing 4, resulting in a compact structure. Whether integrated onto the surface of the screen or positioned on the side, it does not affect the normal display area of ​​the screen, ensuring that the pressure data is clearly visible.

[0036] Optionally, when staff inspect along the pipeline's extension direction, they can illuminate the observation window 41 of the monitoring point equipped with a pipeline pressure detection device with a flashlight. When the photosensitive trigger detects that the external light intensity reaches a preset value, it immediately sends a trigger signal to the control unit 2. In response to this signal, the control unit 2 simultaneously performs the following operations: waking up the display screen 31 and sending a detection command to the detection element 12. The detection element 12 then initiates pressure detection, transmitting the collected pressure signal to the control unit 2. The control unit 2 processes the received signal, acquires the pressure data, and transmits the data to the display screen 31 for display. Once the display screen 31 is lit, it displays the current pressure value in real time, allowing staff to quickly and intuitively read monitoring information during inspections.

[0037] Optionally, the photosensitive trigger is a photosensitive sensor.

[0038] Preferably, the photosensitive trigger is positioned above or to one side of the display screen 31.

[0039] Specifically, when the photosensitive trigger is positioned above the display screen 31, the photosensitive trigger is located on one side of the infrared sensor 32; when the photosensitive trigger is positioned on one side of the display screen 31, the photosensitive trigger is located on the side of the display screen 31 furthest from the infrared sensor.

[0040] Specifically, such as Figure 1 and Figure 2 As shown, the display component 3 also includes an infrared sensor 32, which is located in the display area of ​​the observation window 41 and on one side of the display screen 31. The infrared sensor 32 is connected to the control component 2 and is used to communicate with the handheld data acquisition device. The infrared sensor 32 is used to transmit the pressure data acquired by the control component 2 to the handheld data acquisition device.

[0041] With the above-described structure, by integrating an infrared sensor 32 into the display component 3 and placing it within the display area of ​​the observation window 41, operators only need to point the handheld data acquisition device at the observation window 41 to automatically read pressure data via infrared communication. This eliminates the need for opening the cover, wiring, or button operation, significantly improving on-site inspection efficiency, and is particularly suitable for industrial environments with high dust, humidity, or strict explosion-proof requirements. Furthermore, the infrared sensor 32 is located on one side of the display screen 31, sharing the observation window area with it, making full use of the internal space of the housing 4 and avoiding additional openings or external antennas. This results in a compact, clean, integrated design, facilitating equipment miniaturization and modular production. Simultaneously, by incorporating the infrared sensor, the pipeline pressure detection device can display local pressure data on the display screen 31 and upload data to the handheld data acquisition device via the infrared sensor 32, meeting the dual needs of "on-site viewing + background recording." This facilitates the construction of a complete pressure monitoring and data traceability system, avoiding the inefficiencies, errors, and management difficulties caused by traditional manual handwritten records in inspections, and achieving electronic, standardized, and traceable data acquisition.

[0042] Optionally, the infrared sensor serves as an infrared communication window, and the handheld data acquisition device uses wireless infrared communication technology to transmit data with the pipeline pressure detection device. This communication method utilizes infrared light waves to transmit information.

[0043] Specifically, such as Figure 2As shown, the control unit 2 includes: a first circuit section and a second circuit section. The first circuit section is used to control the operation of the detection element 12; to receive and process the pressure signal in the pipeline detected by the detection element 12 to obtain pressure data; and to transmit the pressure data to the display screen 31. The second circuit section is connected to the first circuit section and the photosensitive trigger, respectively. The second circuit section is used to control the first circuit section, the detection element 12, and the display unit 3 to be in a sleep state or an operating state. When the photosensitive trigger sends a trigger signal to the second circuit section, the second circuit section controls the first circuit section, the detection element 12, and the display screen 31 to be in an operating state. When the display screen 31 displays pressure data for a preset time, the second circuit section controls the first circuit section, the detection element 12, and the display screen 31 to be in a standby state.

[0044] With the above-described structure, the second circuit unit is connected to a photosensitive trigger. When a worker shines a flashlight into the observation window, the photosensitive trigger detects that the light intensity has reached a preset value and immediately sends a trigger signal to the second circuit unit, which then wakes up the system and puts it into operation. This design achieves "non-contact wake-up," eliminating the need for physical buttons and making it particularly suitable for harsh industrial environments such as humid, dusty, and explosion-proof environments, significantly improving operational convenience. Simultaneously, after the display screen 31 completes pressure data display and maintains it for a preset time, the second circuit unit automatically controls the first circuit unit, the detection element 12, and the display screen 31 to enter standby mode, cutting off unnecessary power supply and reducing the device's power consumption. This "on-demand wake-up + timed sleep" mechanism effectively extends the device's service life and lifespan. Furthermore, the entire detection process (wake-up → detection → display → sleep) is fully automated, requiring no manual intervention. Workers only need to illuminate the light source to obtain pressure data, achieving an intelligent inspection mode of "reading by light and automatically shutting down," greatly improving inspection efficiency and data accuracy.

[0045] Optionally, the first circuit section is a control circuit used to execute the core control logic of the device; the second circuit section is a standby circuit used to maintain basic power supply and wake-up functions in the device's sleep mode.

[0046] Optionally, the first circuit section and the second circuit section are jointly disposed on the same printed circuit board (PCB) substrate to achieve a highly integrated design, which is beneficial to reduce the overall size, reduce the number of connecting cables, and improve system reliability.

[0047] Specifically, such as Figure 1 and Figure 2As shown, the pressure detection component 1 also includes: a protective sleeve 13 and a connector 14. The protective sleeve 13 has a first installation space 10 inside, and the housing 4 is disposed at the top of the protective sleeve 13. The connector 14 has a first guide channel 11 inside, one end of the connector 14 is connected to the protective sleeve 13, and the other end of the connector 14 is used to connect to the connection port on the pipeline, so that the medium in the pipeline is conducted to the detection end of the detection element 12 through the connection port and the first guide channel 11.

[0048] With the above-described structural design, the protective sleeve 13 protects the detection element 12. The protective sleeve 13, as the main structure of the pressure detection component 1, serves both to house the detection element 12 and as an intermediate load-bearing component connecting the housing 4 and the connector 14, forming an integrated structure from top to bottom: "housing 4 – protective sleeve 13 – connector 14". This design is compact, has high mechanical strength, effectively resists external impacts and vibrations, and improves the operational stability of the device in harsh environments such as mines and tunnels. Meanwhile, the connector 14 has a first guide channel 11 inside, which, after connecting to the pipeline connection port, forms a continuous pressure transmission channel from the pipeline to the detection element 12. The medium pressure is transmitted unobstructed through the path of connection port → first guide channel 11 → detection end, avoiding pressure loss or response lag, ensuring that the detection results accurately reflect the actual pressure state of the pipeline, and improving measurement accuracy.

[0049] Optionally, to facilitate the entry of the first wire from the first mounting space 10 into the second mounting space 42, the first mounting space 10 and the second mounting space 42 are connected.

[0050] Furthermore, such as Figure 1 and Figure 2 As shown, the protective sleeve 13 includes: a sleeve body 131 and a limiting seat 132. The top end of the sleeve body 131 is connected to the housing 4. The sleeve body 131 has an installation cavity 101, and part of the detection element 12 is disposed in the installation cavity 101. The limiting seat 132 is located at the bottom of the sleeve body 131. The limiting seat 132 has an insertion part and a limiting part connected in sequence. The insertion part is inserted into the installation cavity 101 to support the detection element 12. The limiting part is located at the bottom end of the sleeve body 131 and abuts against the protective sleeve 13. The insertion part and the limiting part are respectively provided with a first connecting channel 102 and a second connecting channel 103. The first connecting channel 102 is connected to the installation cavity 101 and the second connecting channel 103 respectively. The detection end of the detection element 12 is located in the first connecting channel 102. The connector 14 is located at the bottom of the limiting seat 132 and is detachably connected to the limiting seat 132.

[0051] With the above-described structure, a sleeve body 131 is provided, and an installation cavity 101 is provided inside the sleeve body 131 to facilitate the installation of a portion of the detection element 12 (i.e., the main body of the detection element 12) within the installation cavity 101, thereby effectively protecting the detection element 12. Furthermore, a limiting seat 132 is provided at the bottom of the sleeve body 131, and its insertion part supports the detection element 12, ensuring that the detection element 12 will not shift or be damaged due to vibration or impact during long-term operation, thus improving the mechanical stability and service life of the system. Simultaneously, the insertion part and the limiting part are respectively provided with a first connecting channel and a second connecting channel, forming a continuous pressure transmission path from the pipeline to the detection element. This design ensures that the medium pressure can be transmitted to the detection end of the detection element without damage and quickly, avoiding pressure loss or response lag, and improving the accuracy and real-time performance of the measurement. In addition, the connector 14 and the limiting seat 132 are detachably connected (e.g., by threads, snaps, etc.), allowing for the selection of a suitable connector according to actual conditions, thus improving the adaptability of the device.

[0052] Furthermore, the mounting cavity 101, the first connecting channel 102, and the second connecting channel 103 form a first mounting space 10.

[0053] Furthermore, the mounting cavity 101 and the detection element 12, as well as the first connecting channel and the detection element 12, are sealed. The sleeve body 131 and the limiting seat 132 are fixedly connected.

[0054] Furthermore, the insertion part is inserted into the mounting cavity 101, and a second sealing ring is used to seal the outer wall of the insertion part and the inner wall of the mounting cavity 101. Additionally, a sealing gasket is provided between the top of the insertion part and the detection element 12.

[0055] Furthermore, the connection between the limit seat 132 and the connector 14 is sealed with a first sealing ring 9 to prevent media leakage.

[0056] Furthermore, a dustproof ring is provided at the connection between the housing 4 and the sleeve body 131.

[0057] Optionally, the protective sleeve 13 is made of stainless steel, and the connector 14 is made of metal to enhance its impact and collision resistance.

[0058] Specifically, such as Figure 1 As shown, the pipeline pressure testing device also includes: a connector and a locking element 5. The connector is installed on the connection port of the pipeline and is fixedly connected to the pipeline. The connector protrudes from the pipeline and is provided with a second guide channel. The connector 14 is sleeved on the connector and is sealed to the connector. The connection port is connected to the first guide channel 11 through the second guide channel. The locking element 5 locks the connector 14 to the connector when the connector 14 is sleeved on the connector.

[0059] By adopting the above-described structural design, the connector 14 is fitted onto the connecting piece protruding from the pipeline, and quickly locked in place with the locking piece 5. This eliminates the need for threading or welding, significantly simplifying the on-site installation process. It is particularly suitable for applications with limited space or frequent disassembly / reassembly, improving construction efficiency. Simultaneously, the connecting piece is fixedly connected to the pipeline, serving as an independent interface reference; the connector 14 is fitted onto it and locked in place by the locking piece 5, forming a "fitting + locking" mechanical connection. This structure effectively resists vibration, impact, and thermal expansion and contraction stress during pipeline operation, preventing connection failure or leakage due to loosening. Furthermore, the locking piece 5 locks the connector 14 to the connecting piece after installation, preventing accidental detachment due to accidental contact, vibration, or internal pressure pulsation, greatly enhancing the inherent safety and long-term reliability of the device.

[0060] Alternatively, the connector can be a separate connecting pipe, which is fixedly connected to a connection port on the pipeline (e.g., by welding or gluing). Or the connector can be a three-way valve, which connects two adjacent pipeline segments and protrudes at one of the pipe ports for connection to the fitting 14.

[0061] Optionally, the connector 14 has two spaced-apart first connecting holes extending radially along the connector 14. The connector has two second connecting holes that mate with the two first connecting holes, with each first connecting hole corresponding to the other two second connecting holes. The locking element 5 is a U-shaped pin. When the connector 14 is fitted onto the connector, each first connecting hole and each corresponding second connecting hole are positioned opposite each other, and the U-shaped pin is inserted into each first connecting hole and each second connecting hole to achieve locking.

[0062] It should be noted that, through the above locking method, after the joint and the connecting piece are sleeved and locked by the U-pin, the mating surfaces between the two are reliably pressed together, causing the sealing element set therebetween (such as between the inner wall of the joint and the outer periphery of the connecting piece) to undergo elastic deformation, forming an effective seal, thereby reliably preventing pipeline medium leakage and ensuring the sealing of the pressure transmission path and the safety of system operation.

[0063] Specifically, such as Figure 1 and Figure 2As shown, the pipeline pressure testing device also includes a dustproof component 6. The dustproof part of the dustproof component 6 is used to insert into the first guide channel 11 to seal the first guide channel 11. With this structural arrangement, by incorporating the dustproof component 6, external impurities such as dust, debris, and moisture can be effectively prevented from entering the first guide channel 11 and the internal pressure transmission path during storage, transportation, and pre-installation stages after the pipeline pressure testing device leaves the factory and before on-site installation. This avoids channel blockage or contamination of the pressure-sensing surface of the testing component, thereby ensuring the normal transmission of pressure signals and testing accuracy. Furthermore, the dustproof component has a simple structure and is easy to disassemble and assemble; it can be easily pulled out during installation without affecting the normal assembly of joints and connecting parts.

[0064] Specifically, such as Figure 1 and Figure 2 As shown, the pipeline pressure detection device also includes an energy storage component 8, which is electrically connected to the control component 2 and provides electrical energy. This structural arrangement, by incorporating the energy storage component 8 and its electrical connection to the control component 2, provides stable and continuous power support for the entire pipeline pressure detection device. The energy storage component 8 eliminates the need for a continuous external power supply, making it particularly suitable for remote areas with difficult wiring or no mains power supply, such as mines, tunnels, and underground utility tunnels. As an independent power unit, the energy storage component enables the equipment to operate completely self-sufficiently.

[0065] Furthermore, the energy storage component 8 is housed within the second mounting space 42 of the housing 4. The energy storage component 8 is connected to the second circuit section of the control component 2. The second circuit section can dynamically adjust the power supply on / off according to the system's operating status, achieving efficient distribution and optimized management of the energy in the energy storage component 8. For example, during non-inspection periods, the entire unit can be controlled to enter a low-power sleep mode, maintaining only the micro-current standby of the second circuit section and the photosensitive trigger. When a light-triggered signal is received, the second circuit section immediately activates the energy storage component 8 to supply power to the first circuit section, the detection element 12, and the display screen 31, realizing an intelligent power supply mechanism of "on-demand wake-up and instant response."

[0066] Optionally, the energy storage component 8 is an energy storage battery.

[0067] Specifically, such as Figure 3 As shown, the pipeline pressure testing device also includes a mounting bracket 7, which is mounted on the housing 4 and located on the side of the housing 4 away from the observation window 41. The mounting bracket 7 is used to engage with the mounting mating part to fix the pipeline pressure testing device. With this structural arrangement, by setting up the mounting bracket 7, workers can directly suspend the device on the pipeline support, equipment beam, or special mounting rod, etc., without using complicated tools or bolt tightening operations, achieving rapid installation with "one-click installation" and significantly improving on-site construction efficiency.

[0068] Specifically, the pipeline pressure testing device is an intrinsically safe pipeline pressure testing device.

[0069] Optionally, the working process of the pipeline pressure detection device is as follows: During installation, the dustproof component 6 is first pulled out of the first guide channel 11 of the connector. Then, the connector 14 is fitted onto the connector at the pipe connection port, and mechanical locking is achieved through the locking component 5 (such as a U-pin), thus realizing a reliable connection between the device and the pipeline. After the pipeline pressure detection devices at all monitoring points are installed, the pipeline begins to be circulated with the medium. At this time, all devices are in a low-power standby state.

[0070] When the staff begins the inspection, upon reaching each monitoring point equipped with a pipeline pressure detection device, they illuminate the observation window 41 of the device with a flashlight. When the photosensitive trigger detects that the external light intensity has reached a preset value, it immediately sends a trigger signal to the second circuit section of the control unit 2; the second circuit section of the control unit 2 responds to the signal and simultaneously performs the following operations: controlling the energy storage unit 8 to supply power, and simultaneously sending a start command to the first circuit section.

[0071] Upon receiving the instruction, the first circuit section of control unit 2 wakes up display screen 31 and sends a pressure detection instruction to detection element 12. Detection element 12 then initiates pressure detection, transmitting the collected pressure signal to control unit 2. The first circuit section of control unit 2 processes the received signal, acquires the pressure data, and transmits the data to display screen 31 for display. Once illuminated, display screen 31 displays the current pressure value in real time, facilitating quick and intuitive reading of monitoring information by staff during inspections.

[0072] At the same time, the staff sends a communication request to the infrared sensor 32 through the handheld data acquisition device. After receiving the signal, the infrared sensor 32 obtains the pressure data processed by the first circuit section of the control component 2, and uploads the pressure data to the handheld data acquisition device through wireless infrared communication, so as to realize the automatic acquisition and electronic storage of pressure information.

[0073] When the display screen 31 continuously displays pressure data for a preset time (e.g., 10 seconds), the second circuit section automatically controls the first circuit section, the detection element 12 and the display screen 31 to enter standby mode, cuts off unnecessary power supply, turns off the display screen, and the system returns to low power mode, waiting for the next light exposure trigger, thereby realizing the intelligent operation mechanism of "waking up when exposed to light and automatically shutting down at set times".
