[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0035] Please see Figures 1 to 2This embodiment provides a transverse slope monitoring device for precast bridge beams, including a connecting assembly 1, a liquid reservoir 2, a first sensing assembly 3, a second sensing assembly 4, a control unit 5, and a fixing assembly 6. The connecting assembly 1 includes a first hose 11 and a second hose 12, which are coaxially arranged opposite to each other. The liquid reservoir 2 is connected to both the first hose 11 and the second hose 12, and contains liquid. The first sensing assembly 3 includes a first pressure sensor 31 and a first housing 32, which is connected to one end of the first hose 11 extending outward. The first pressure sensor 31 is positioned... Above the first housing 32, a first pressure sensor 31 is used to detect the pressure inside the first housing 32; the second sensing component 4 includes a second pressure sensor and a second housing, the second housing is connected to one end of the second hose 12 extending outward, the second pressure sensor is located above the second housing, and the second pressure sensor is used to detect the pressure inside the second housing; the control unit 5 is electrically connected to the first sensing component 3 and the second sensing component 4; the fixing component 6 includes a first fixing member 61 and a second fixing member 62, the first fixing member 61 is located below the first housing 32, and the second fixing member 62 is located below the second housing.

[0036] In this embodiment, the first hose 11 and the second hose 12 are tubes with equal cross-sections made of flexible material, which can improve the sensitivity of pressure transmission. The first hose 11 and the second hose 12 are arranged symmetrically along the axial direction and extend in parallel to form a communicating vessel system for transmitting liquid static pressure.

[0037] The reservoir 2 is a sealed container that stores a certain amount of liquid to form a reference liquid level. The reservoir 2 is connected to the first hose 11 and the second hose 12 respectively. The first hose 11 provides stable pressure to the first sensing component 3, and the second hose 12 provides stable pressure to the second sensing component 4.

[0038] The first box 32 and the second box are rigid containers with open tops, and are connected to the liquid reservoir 2 through the end ports of the first hose 11 and the second hose 12, respectively. The liquid level inside the box is determined by the extension length of the corresponding hose.

[0039] The first pressure sensor 31 and the second pressure sensor convert changes in the static pressure of the liquid inside the first housing 32 and the second housing into electrical signals. The first pressure sensor 31 is installed inside the first housing 32, and the second pressure sensor is installed inside the second housing. The relative height difference between the point and the liquid surface in the reservoir 2 can be measured using the first pressure sensor 31 and the second pressure sensor, thus obtaining the height difference between the first sensing component 3 and the second sensing component 4. Dividing this height difference by the distance between the two measuring points yields the current slope value of the precast beam formwork 9. Preferably, the first pressure sensor 31 and the second pressure sensor can be highly sensitive diffused silicon miniature pressure sensors to improve anti-interference capabilities and achieve high-precision continuous monitoring.

[0040] The control unit 5 receives the electrical signal difference between the first pressure sensor 31 and the second pressure sensor, calculates the height difference between the first tank 32 and the second tank relative to the reference liquid level of the reservoir 2, and then converts it into a lateral slope value.

[0041] The first fixing member 61 and the second fixing member 62 refer to mounting bases with adsorption surfaces, which are respectively set at the bottom of the first housing 32 and the second housing. Preferably, the housings are fixed to the surface of the precast beam template 9 by magnetic attraction or bolt fastening. The liquid forms a stable reference in the communication system formed by the liquid reservoir 2 and the first hose 11 and the second hose 12. When the precast beam template 9 tilts, the height difference of the liquid level in the first housing 32 and the second housing is detected by the pressure sensor and transmitted to the control unit 5 to complete the slope calculation.

[0042] In this embodiment, a communication system is formed between the first hose 11 and the second hose 12 and the reservoir 2, ensuring stable pressure transmission between the reference liquid level in the reservoir 2 and the first and second tanks, eliminating interference from liquid level fluctuations caused by environmental vibrations or temperature changes. The first and second pressure sensors detect changes in the static pressure of the liquid within the first and second tanks, converting the pressure signals into electrical signal differences. The control unit 5 calculates the real-time height difference between the first and second tanks relative to the reference liquid level in the reservoir 2 based on this difference, and accurately calculates the lateral slope value by combining the distance between the two measuring points. The first and second fixing members 61 and 62 securely install the tanks onto the surface of the precast beam template 9 using magnetic attraction or bolt fastening, ensuring synchronous displacement between the device and the precast beam template 9 during measurement. This device combines the principle of communicating vessels with pressure detection, eliminating the need for external reference points. It has a simple structure, strong resistance to environmental interference, and can reflect real-time changes in the slope of the precast beam, providing reliable data support for construction quality.

[0043] In some embodiments, the connecting component 1 further includes a connecting main pipe 13 and a three-way pipe 14. The connecting main pipe 13 is connected to the bottom of the liquid reservoir 2. The three-way pipe 14 has a first interface, a second interface and a third interface. The first interface and the third interface are arranged opposite to each other. The second interface is arranged between the first interface and the third interface. The second interface is connected to the connecting main pipe 13. The first interface is connected to the first hose 11. The third interface is connected to the second hose 12.

[0044] In this embodiment, the three-way pipe 14 adopts a symmetrical layout with the first and third interfaces facing each other, so that the first hose 11 and the second hose 12 form symmetrical branches along the axial direction, eliminating the difference in liquid flow resistance caused by pipeline offset and ensuring the balance of pressure transmission in the two hoses. The connecting main pipe 13 is made of rigid material and is stably connected to the bottom of the reservoir 2, avoiding the stress concentration problem at the connection point caused by flexible deformation when the hose is directly connected to the reservoir 2. The three-way pipe 14 is axially connected to the connecting main pipe 13 through the second interface, forming a stable pipeline structure with three-point support, reducing the risk of interface loosening caused by external vibration or temperature changes. The first hose 11 and the second hose 12 extend symmetrically through the first and third interfaces of the three-way pipe 14, respectively, maintaining a constant relative position between the hose and the reservoir 2, and preventing interference from liquid surface fluctuations caused by pipeline twisting or bending. This embodiment enhances the mechanical stability of each interface of the connecting component 1, improves the reliability of liquid static pressure transmission, and provides a stable physical basis for the accurate detection of the pressure sensor.

[0045] In some embodiments, the side of the first housing 32 is provided with a first extension end, which is sealed to the first hose 11; the side of the second housing is provided with a second extension end, which is sealed to the second hose 12.

[0046] In this embodiment, the connections between the first extension end, the second extension end, and the first hose 11 and the second hose 12 are secured with clamps or heat-sealed to ensure a tight fit, preventing loosening or cracking of the sealing surface due to pipe bending or vibration. This embodiment effectively prevents external contaminants from entering and internal liquid from leaking, maintaining the stability of pressure transmission between the first housing 32, the second housing, and the first hose 11 and the second hose 12, ensuring the accuracy of the pressure sensor's detection data. By optimizing the sealing structure, the long-term reliability of the monitoring device in complex construction environments is further enhanced.

[0047] In some embodiments, the first hose 11 is sleeved around the periphery of the first extension end; the second hose 12 is sleeved around the periphery of the second extension end.

[0048] In this embodiment, by forming a sleeve structure in which the first hose 11 is sleeved around the first extension end and the second hose 12 is sleeved around the second extension end, an annular contact surface is created. This radial tight fit enhances the sealing effect and reduces the risk of axial leakage. The sleeve structure avoids gaps caused by slight misalignment in traditional flat-end connections, reducing the possibility of liquid overflow or air intrusion. The sleeve section, by uniformly wrapping the outer walls of the first and second extension ends, eliminates the risk of seal failure caused by localized stress concentration, ensuring the integrity and stability of the pressure transmission path and effectively improving the sealing performance at the connection between the hose and the extension end. This embodiment improves the long-term sealing reliability of the monitoring device in dynamic environments by optimizing the sealing contact form.

[0049] In some embodiments, the connection component 1 further includes a first tube clamp 15 and a second tube clamp, the first tube clamp 15 engaging at the connection between the first extension end and the first hose 11; the second tube clamp engaging at the connection between the second extension end and the second hose 12.

[0050] In this embodiment, by setting a first clamp 15 at the connection between the first extension end and the first hose 11, and a second clamp at the connection between the second extension end and the second hose 12, the sealing effect between the first hose 11 and the first extension end, and between the second hose 12 and the second extension end, is significantly enhanced. The first clamp 15 and the second clamp apply radial pressure to the connection through their interlocking action, ensuring a tight fit between the first hose 11 and the first extension end, and between the second hose 12 and the second extension end, eliminating the risk of liquid leakage caused by assembly gaps or material deformation. The circumferential constraint force of the first clamp 15 and the second clamp forms a uniform sealing ring, effectively preventing the intrusion of external contaminants and the overflow of internal liquid, avoiding the sealing failure problem caused by local stress relaxation in traditional adhesive bonding or simple sleeve processes. This embodiment improves the vibration resistance and temperature change resistance of the connection through mechanical reinforcement, ensuring that the monitoring device maintains stable sealing performance under dynamic operating conditions for a long time.

[0051] In some embodiments, the monitoring device further includes a first wire 7 and a second wire 8, wherein the first wire 7 connects the first pressure sensor 31 to the control unit 5; and the second wire 8 connects the second pressure sensor to the control unit 5.

[0052] In this embodiment, the data from the first pressure sensor 31 is converted, analyzed, and displayed by a secondary instrument in the control unit 5 via the first wire 7; the data from the second pressure sensor is converted, analyzed, and displayed by a secondary instrument in the control unit 5 via the second wire 8, ensuring the independence and stability of the pressure signal transmission. The independent wiring of the first wire 7 and the second wire 8 avoids signal cross-interference and improves the accuracy of the detection data from the first and second pressure sensors. The direct connection structure of the first wire 7 and the second wire 8 simplifies the internal wiring path of the monitoring device, reduces the risk of wire tangling or poor contact, and facilitates installation and maintenance. The fixed connection method between the first wire 7 and the control unit 5 and the first pressure sensor 31, and the fixed connection method between the second wire 8 and the control unit 5 and the second pressure sensor, enhances the resistance to external vibration and electromagnetic interference, ensuring long-term stable operation of the monitoring device under complex working conditions.

[0053] In some embodiments, the first fixing member 61 is a magnet; the second fixing member 62 is a magnet.

[0054] In this embodiment, magnetic attraction is used to achieve rapid alignment and secure connection, avoiding the wear risk of traditional mechanical clips. The tight fit between the magnets enhances the sealing effect of the contact surfaces, ensuring the long-term stable operation of the monitoring device.

[0055] The present invention, compared with the prior art, has the following advantages when using the above technical solution: The present invention provides a transverse slope monitoring device for precast bridge beams, including a connecting component 1, a liquid reservoir 2, a first sensing component 3, a second sensing component 4, a control unit 5, and a fixing component 6. Through a communication system formed by the first hose 11, the second hose 12, and the liquid reservoir 2, high-precision slope monitoring is achieved using the principle of hydrostatic pressure transmission. The first pressure sensor 31 and the second pressure sensor respectively detect pressure changes within the first housing 32 and the second housing. The control unit 5 calculates the height difference and converts it into a slope value, eliminating interference from environmental vibrations or temperature fluctuations on the reference liquid level. The symmetrical layout of the three-way pipe 14 and its rigid connection to the main connecting pipe 13 ensures balanced pressure transmission between the first hose 11 and the second hose 12, avoiding detection errors caused by pipe misalignment. The sleeve structure of the first extension end and the second extension end with the first hose 11 and the second hose 12, combined with the first pipe clamp 15 and the second pipe clamp for reinforcement, forms multiple layers of sealing protection, preventing liquid leakage and contaminant intrusion through radial tightness and circumferential constraint. The independent wiring design of the first conductor 7 and the second conductor 8 prevents signal cross-interference. Combined with the rapid installation characteristics of the magnetic first fixing component 61 and the second fixing component 62, it enhances the device's vibration resistance and displacement synchronization capabilities. The diffused silicon miniature first pressure sensor 31 and the second pressure sensor, combined with the sealed first housing 32 and the second housing, improve electromagnetic interference resistance and ensure continuous monitoring stability under complex working conditions. This device achieves efficient slope detection without the need for external reference by optimizing the pipeline layout, sealing structure, and signal transmission method, providing reliable data support for precast beam construction.
