Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pressure testing technology for water conservancy projects, and in particular to a water pressure testing instrument for water conservancy projects. Background Technology
[0002] Water pressure monitoring in water conservancy projects mainly involves deploying pressure sensors (such as piezoresistive and fiber optic sensors) to monitor pressure changes in key components such as pipelines and dams in real time. This is combined with SCADA systems for data acquisition and analysis, and the setting of early warning thresholds to automatically alarm for abnormal water pressure. Simultaneously, this is supplemented by regular manual inspections (portable pressure gauges, pressure tests) and intelligent algorithms (trend prediction, operating condition simulation) to form a multi-dimensional monitoring system. This ensures the safe and stable operation of water conservancy facilities under normal and extreme conditions, effectively prevents risks such as leakage and pipe bursts, and provides accurate data support for project scheduling and maintenance.
[0003] In the prior art, Chinese utility model patent with authorization announcement number CN217155678U discloses an overpressure detection device for water conservancy projects, which relates to the field of water pressure detection equipment technology. Addressing the problem that existing water pressure detection methods in water conservancy projects use a rope-pulling method to insert a water pressure sensor, the flow of river water can lead to inaccurate detection results, the following solution is proposed: It includes a fixed plate and a slider. A support frame is fixedly installed at the top of the fixed plate, and a fixed sleeve is fixedly installed at the bottom of the support frame. An internally threaded tube is slidably installed inside the fixed sleeve. A threaded rod is rotatably installed at the bottom of the support frame, and the threaded rod is located inside the internally threaded tube, engaging with the internally threaded tube. A first sliding groove is formed through the side wall of the fixed sleeve.
[0004] Problems compared with existing technologies: Some existing water conservancy projects use water pressure testing instruments that can only perform water pressure testing at a fixed position relative to the bank. Multiple tests require multiple relocations, resulting in low continuous testing efficiency of water pressure testing instruments in water conservancy projects.
[0005] Therefore, there is an urgent need for a water pressure testing instrument for water conservancy projects. Utility Model Content
[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a water pressure testing instrument for water conservancy projects.
[0007] The present invention solves its technical problem through the following technical solution: a water pressure testing instrument for water conservancy projects, including a base, a column installed on the base, a horizontal arm rotatably connected to the column, and a rotating mechanism set on the top of the column for adjusting the direction of water pressure testing in water conservancy projects, and also including an extension mechanism set on the rotating mechanism for adjusting the distance of water pressure testing in water conservancy projects.
[0008] As a further embodiment of this utility model: the rotating mechanism includes a mounting frame, which is welded to both sides of the column. A worm gear is rotatably connected to one end of the mounting frame, and a worm wheel is rotatably connected to the top of the column. A rotating shaft is fixedly installed in the middle of the worm wheel. The worm gear and the worm wheel are connected in a transmission manner, and the cross arm is fixed above the rotating shaft by bolts.
[0009] As a further embodiment of this utility model: the extension mechanism includes an extension arm, which is slidably connected to the inner wall of the cross arm. A cavity is provided at the tail of the extension arm. A pressing plate is slidably connected to one end of the cavity. A triangular block is fixedly installed in the middle of the pressing plate. A helical spring is fixedly installed at the bottom of the cavity. The free end of the helical spring is fixedly connected to the pressing plate. Multiple slots are evenly provided on both sides of the cross arm.
[0010] As a further embodiment of this utility model: a detection mechanism is provided at one end of the extension arm for detecting water pressure in water conservancy projects. The detection mechanism includes a square tube, which is fixed to one end of the extension arm by bolts. A drive motor is fixedly installed on the top of the square tube, and a lead screw is fixedly installed on the rotating end of the drive motor. A lifting rod is driven and connected to the outside of the lead screw, and a pressure sensor is fixedly installed at one end of the lifting rod.
[0011] As a further improvement of this utility model: a battery pack is fixedly installed on the top of the base, and multiple ground nails are rotatably connected to the outer side of the base.
[0012] As a further improvement of this utility model, a handle is fixedly installed at one end of the extension arm.
[0013] As a further improvement of this utility model: a crank handle is fixedly installed at one end of the worm gear, and a paddle is provided above the extrusion plate.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0015] 1. The worm gear is driven to rotate by a crank handle, which in turn drives the worm wheel to rotate. The worm wheel, through its self-locking property with the worm gear, drives the rotating shaft to rotate, which in turn drives the horizontal arm to rotate. This adjusts the direction of water pressure testing in hydraulic engineering projects. The extension arm is slid along the horizontal arm by pulling the handle. The helical spring compresses the extrusion plate, which in turn compresses the triangular block. The triangular block engages with multiple slots to position the extension arm. In conjunction with the worm wheel, continuous water pressure testing can be performed at multiple positions at different distances from the bank without the need for multiple position changes, thus ensuring the continuous testing efficiency of the water pressure testing instrument in hydraulic engineering projects.
[0016] 2. The drive motor drives the lead screw to rotate, which in turn drives the lifting rod to rise and fall. The lifting rod then drives the pressure sensor to rise and fall, enabling the water pressure testing instrument for water conservancy projects to perform water pressure testing at various depths, thus enriching the functionality of the water pressure testing instrument for water conservancy projects.

The rotating mechanism includes a mounting frame 101, which is welded to both sides of the column 200. One end of the mounting frame 101 is rotatably connected to a worm gear 102, and one end of the worm gear 102 is fixed by bolts. A crank handle 110 is provided, which drives the worm gear 102 to rotate. A worm wheel 103 is rotatably connected to the top of the column 200. The worm gear 102 drives the worm wheel 103 to rotate.

The rotating shaft 104 drives the cross arm 300 to rotate. The system also includes components positioned above the rotating mechanism. An extension mechanism is provided for adjusting the distance of water pressure testing in hydraulic engineering projects. The extension mechanism includes an extension arm 201, which is slidably connected to the inner wall of a horizontal arm 300. One end of the extension arm 201 is bolted to a handle 500, which pulls the extension arm 201 to slide along the horizontal arm 300. A cavity 202 is cut into the tail of the extension arm 201, and a pressing plate 203 is slidably connected to one end of the cavity 202. The bottom of the cavity 202 is bolted to...
