Description

Technical Field

[0001] This utility model relates to the field of dam monitoring technology, specifically to a dam tilt monitoring device. Background Technology

[0002] Dam tilt monitoring is a key means of ensuring the structural safety of dams. By tracking changes in dam tilt in real time, it can provide timely warnings of potential instability risks, prevent disasters such as dam failure, and protect the safety of people and property downstream. At the same time, it provides data for dam maintenance and reinforcement, extends the service life, and helps scientific decision-making and proactive prevention and control in water conservancy project management.

[0003] In existing technologies, wireless tilt alarm devices are typically used to monitor the tilt of dams. During use, the tilt sensor inside the wireless tilt alarm device is usually fixed to the surface of the monitoring point on the dam with fasteners such as bolts. However, the external protective structure of the tilt sensor installed outdoors is relatively weak, and the sensor is susceptible to moisture or corrosion in rainy weather. Therefore, a dam tilt monitoring device is proposed to solve the above problems. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A dam tilt monitoring device includes a protective mechanism, wherein a wireless tilt alarm is installed inside the protective mechanism;

[0006] The protective mechanism includes a fence, with extension plates symmetrically fixedly connected to both sides of the lower inner wall of the fence. Each extension plate has mounting holes on its surface. Lifting lugs are symmetrically fixedly connected to the outer sidewalls of the fence. Each lifting lug has a lifting ring fitted onto its outer wall. The inner diameter of the lifting ring is larger than the diameter of the lifting lug. A steel wire rope is fixedly connected to one end of the outer wall of each lifting ring. An end plate is fixedly connected to the other end of the steel wire rope. Bolt holes are provided at both the upper and lower ends of the surface of the end plate.

[0007] As a further embodiment of this utility model: a cable hole is provided in the center of the front of the fence, and a dustproof brush is glued and fixed to the inner side of the cable hole. The dustproof brush is arranged in a ring. Threaded holes are symmetrically provided on the upper ends of both sides of the outer wall of the fence.

[0008] As a further embodiment of this utility model: the protective mechanism also includes a top cover, the inner side wall of which is bonded and fixed with a sealing gasket, and the outer sides of the sealing gasket are symmetrically provided with through holes, and the inner wall of each through hole is connected with a bolt.

[0009] As a further embodiment of this utility model: the inner side of the top cover is fitted onto the upper end of the outer wall of the enclosure, and the inner surface of the sealing gasket abuts against the outer wall of the enclosure, and the ends of the bolts are respectively inserted into the threaded holes and threadedly tightened.

[0010] As a further embodiment of this utility model: a rain shield is fixedly connected to the outer wall of the top cover and directly above the cable hole. The rain shield is arched in shape, and the middle part of the rain shield is located above both sides.

[0011] As a further embodiment of this utility model: the wireless tilt alarm includes a tilt sensor, the bottom surface of the tilt sensor is fixedly mounted with a mounting ear, and a power transmission line is connected to the center of the front of the tilt sensor.

[0012] As a further embodiment of this utility model: the outer walls of the tilt sensor abut against the inner walls of the enclosure on both sides, the surface of the mounting ear abuts against the inner walls of the enclosure on all four sides, the bottom surface of the mounting ear is supported and connected to each extension plate, the power transmission line is connected through the cable hole, and the surface of the power transmission line abuts against the dustproof brush.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model isolates and protects the tilt sensor by using a fence and a top cover, thereby preventing external rainwater from directly contacting the sensor and preventing corrosion of the sensor shell and fasteners connecting the dam body, which helps to extend the life of the sensor. The power transmission line of the tilt sensor connected to the external solar power supply box passes through the cable hole on the surface of the fence. A dustproof brush is set on the inside of the cable hole to prevent external dust and debris from contacting the sensor through the hole. A rain shield is set on the top cover above the cable hole to prevent rainwater from contacting the sensor cable interface.

[0015] (2) A steel wire rope is attached to the outside of the enclosure. The end plate connected to the end of the steel wire rope can be fixed to the top of the dam. When it is necessary to retrieve the tilt sensor that is fixed on the slope of the dam, the operator wearing a safety belt can first separate the top cover from the enclosure, then disassemble the fasteners connecting the enclosure and the dam, and then fix the top cover to the enclosure. The operator above the dam can then use the steel wire rope to retrieve the entire protective mechanism along with the tilt sensor at the same time, so as to avoid accidental fall when retrieving the equipment.

Each lifting lug 105 has a lifting ring 111 fitted onto its outer wall. The inner diameter of the lifting ring 111 is larger than the diameter of the lifting lug 105. A steel wire rope 112 is fixedly connected to one end of the outer wall of each lifting ring 111, and an end plate 113 is fixedly connected to the other end of the steel wire rope 112. Bolt holes are provided at both the upper and lower ends of the surface of the end plate 113. Figure 1 As shown, after the end plate 113 is fixed to the top of the dam, the enclosure 101 is supported by steel wire rope 112 to prevent the enclosure 101 from falling off accidentally during the installation process.

[0025] A cable hole 103 is provided in the center of the front of the enclosure 101. A dustproof brush 104 is glued and fixed to the inside of the cable hole 103. The dustproof brush 104 is arranged in a ring. Threaded holes 102 are symmetrically provided at the upper ends of both sides of the outer wall of the enclosure 101. Figure 2 As shown, the dustproof brush 104 reduces the gaps in the cable hole 103 connection and reduces the amount of dust entering the enclosure 101.

[0026] The protective mechanism 1 also includes a top cover 106. A sealing gasket 109 is adhered and fixed to the inner wall of the top cover 106. Symmetrical through holes 108 are formed on both sides of the outer surface of the sealing gasket 109. Bolts 110 are threaded through the inner wall of each through hole 108. The top cover 106 is fitted inside the upper part of the outer wall of the enclosure 101, and the inner surface of the sealing gasket 109 abuts against the outer wall of the enclosure 101. The ends of the bolts 110 are inserted into threaded holes 102 and tightened by threads. Figure 5 As shown, the sealing gasket 109 is made of rubber, which improves the sealing effect.

[0027] A rain shield 107 is fixedly connected to the outer wall of the top cover 106 and directly above the cable hole 103. The rain shield 107 is arched in shape, with its center positioned above both sides. Figures 1-2 As shown, the rain shield 107 prevents rainwater from falling directly into the cable hole 103.

[0028] The wireless tilt alarm 2 includes a tilt sensor 201, with a mounting ear 202 fixedly installed on the bottom surface of the tilt sensor 201, and a power transmission line 203 connected to the center of the front of the tilt sensor 201. Figure 4 As shown, the wireless tilt alarm 2 is specifically the QYQB-01 model wireless tilt alarm. The tilt sensor 201 is one of the internal components, and its specific working principle is well known in the art and will not be described in detail here.

[0029] The outer walls of the tilt sensor 201 abut against the inner walls of the enclosure 101 on both sides. The surfaces of the mounting ears 202 abut against the inner walls of the enclosure 101 on all four sides. The bottom surface of the mounting ears 202 is supported and connected to each extension plate 114. The power transmission line 203 is internally connected to the cable hole 103, and the surface of the power transmission line 203 abuts against the dustproof brush 104. Figure 3 As shown, the extension plate 114 is set parallel to the mounting ear 202, so as not to affect the tilt sensor 201's monitoring of the dam's tilt.

[0030] The working principle of this utility model:

[0031] When it is necessary to install the tilt sensor on the slope of the dam, first fix the end plate 113 to the top of the dam with bolts and other fasteners. Then fix the solar power box to the top of the dam. Extend the power transmission line 203 to the installation point of the tilt sensor 201. Then, the operator wearing a safety belt carries the protective mechanism 1 and the wireless tilt alarm 2 down to the slope of the dam for installation. Insert the tilt sensor 201 into the enclosure 101. The preset holes on the surface of the mounting ear 202 are aligned with each mounting hole 115. Then the bolts and other fasteners can be passed through the mounting ear 202 and the mounting hole 115 and fixed to the surface of the dam. Then, the power transmission line 203 is passed through the cable hole 103 and connected to the tilt sensor 201. Finally, the top cover 106 is closed on the top of the enclosure 101. Then the bolt 110 is passed through the through hole 108 and locked and fixed with the threaded hole 102.
