Description

Technical Field

[0001] The utility model relates to the technical field of water diversion projects, in particular to an on-line settlement displacement observation device. Background Art

[0002] The settlement of the dam body in the water diversion project may cause deformation of the dam body, such as inclination, distortion, etc., and at the same time, cracks are formed inside or on the surface of the dam body. These cracks not only affect the beauty of the dam body, but more importantly, may weaken the structural strength of the dam body. Therefore, it is necessary to observe the settlement displacement of the dam body. The existing observation method is to monitor the dam body by manually using a total station or laser scanning at regular intervals. However, due to the large amount of observation work and the complexity, the monitoring frequency is relatively low, which leads to the inability to detect the excessive settlement of the dam body in time, resulting in irreparable accidents. Content of the Utility Model

[0003] The purpose of the utility model is to provide an on-line settlement displacement observation device, which can realize on-line real-time monitoring of the settlement value of the dam body and notify the construction personnel to deal with it in time to avoid accidents.

[0004] In order to achieve the above purpose, the utility model provides an on-line settlement displacement observation device, which includes a base, a support rod vertically fixed on the base, and a monitoring device adjustably installed on the support rod; the monitoring device includes a detection cylinder, a bracket for installing the detection cylinder on the support rod, and a trigger device and an alarm device installed on the detection cylinder; a central channel is vertically opened through the center axis position of the detection cylinder; a side wall channel is opened on its side wall, and the side wall channel communicates the outside with the central channel; the trigger device includes a lifting column slidably installed up and down in the central channel and a trigger block fixed on the lifting column; the bottom of the lifting column always abuts against the top of the dam under the action of external force or its own gravity and retracts into the detection cylinder under the supporting force of the dam; the alarm device includes a telescopic column slidably installed in the side wall channel, an elastic component for pushing the inner end of the telescopic column into the central channel, and a sensor fixed outside the side wall channel; the telescopic column can pop outwards under the thrust of the trigger block and contact the sensor, and the sensor is used to detect the contact situation of the telescopic column and transmit the signal to the control center.

[0005] After adopting the above structure, the base is horizontally fixed on the ground, and the position of the monitoring device on the support rod is adjusted so that the bottom of the detection cylinder is pressed tightly on the dam; at this time, the bottom of the lifting column retracts into the detection cylinder under the supporting force of the dam; when the dam settles, the dam descends, and the lifting column also slides down under the action of gravity or external force. After sliding a certain distance, the trigger block contacts the telescopic column and pushes it outwards to contact the sensor. When the sensor senses the contact signal, it means that the settlement value of the dam has exceeded the preset range. Therefore, the signal is transmitted to the control center, and the control center arranges personnel to deal with it to avoid accidents.

[0006] To ensure higher sensitivity of the lifting column, a cover is detachably installed above the detection cylinder, and a compression spring is arranged between the cover and the top of the lifting column.

[0007] To guide the lifting column, ensure its positional accuracy, and avoid jamming, a limit block is provided at the top of the lifting column. The limit block is slidably installed up and down in the central channel. A central hole is provided at the bottom of the central channel, and the diameter of the central hole is the same as that of the lifting column. The lifting column passes through the central hole.

[0008] To facilitate the adjustment of the position of the trigger block for better control of the preset range value of the dam settlement number, the trigger block is adjustably installed on the lifting column, and scale marks for adjusting the position of the trigger block are provided on the lifting column.

[0009] To enable the trigger block to smoothly push the telescopic column to pop out, the contact position between the end of the telescopic column extending into the central channel and the trigger block is an arc surface or a V-shaped surface.

[0010] To ensure the stability of the base fixation, a number of fixing piles for driving into the ground are fixedly installed at the bottom of the base.

[0011] To stably fix the support rod, the base includes a bottom plate and a support frame fixed on the bottom plate. A lower mounting sleeve is fixed on the bottom plate, and an upper mounting sleeve corresponding to the lower mounting sleeve is fixed on the support frame. The support rod passes through the upper mounting sleeve and the lower mounting sleeve from top to bottom and is fixed in the upper mounting sleeve and the lower mounting sleeve.

[0012] To accurately adjust the position of the monitoring device, a scale for adjusting the position of the monitoring device is provided along the axial direction of the support rod.

[0013] After adopting the above technical solutions, the beneficial effects of the present utility model are:

The present utility model realizes the online real-time monitoring of the settlement value of the dam body and notifies the construction personnel to deal with it in time to avoid the occurrence of accidents.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] The orientations mentioned in this specification are based on the orientations of the online settlement displacement observation device of the utility model during normal operation, and are not limited to the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown together, an online settlement displacement observation device includes a base 1, a support rod 2 vertically fixed on the base 1, and a monitoring device 3 adjustable in position mounted on the support rod 2. A plurality of fixed piles driven into the ground are fixedly mounted on the bottom of the base 1 to ensure stable fixation of the base. The base 1 includes a base plate 11 and a support frame 12 fixed on the base plate 11, a lower mounting sleeve 111 is fixed on the base plate 11, an upper mounting sleeve 121 is fixed on the support frame 12 corresponding to the lower mounting sleeve 111, and the support rod 2 passes through the upper mounting sleeve 121 and the lower mounting sleeve 111 from top to bottom in sequence, and is fixed in the upper mounting sleeve 121 and the lower mounting sleeve 111. The verticality is ensured by fixing the lower mounting sleeve 111 and the upper mounting sleeve 121. The support rod 2 is provided with a scale 21 for adjusting the position of the monitoring device 3 along its axial direction.

[0022] The monitoring device 3 comprises a detection tube 31 , a bracket 32 ​​for mounting the detection tube 31 on the support rod 2 , and a trigger device 33 and an alarm device 34 mounted on the detection tube 31 .

[0023] A central channel 311 is formed at the central axis of the detection tube 31 , and a side wall channel 312 is formed on the side wall thereof. The side wall channel 312 connects the outside with the central channel 311 .

[0024] The triggering device 33 includes a lifting column 331 slidably mounted up and down in the central channel 311 and a triggering block 332 fixed on the lifting column 331; the bottom of the lifting column 331 always abuts against the top of the dam 4 under the action of external force or its own gravity and retracts into the detection cylinder 31 under the supporting force of the dam 4.

[0025] The alarm device 34 includes a telescopic column 341 slidably mounted in the side wall channel 312, an elastic component 342 that pushes the inner end of the telescopic column 341 to extend into the central channel 311, and a sensor 343 fixed outside the side wall channel 312 and used to detect the outer end of the telescopic column 341; the contact position between the end of the telescopic column 341 extending into the central channel 311 and the triggering block 332 is an arc surface or a V-shaped surface. In this embodiment, it is an arc surface. Through the setting of the arc surface, it is ensured that the telescopic column 341 can pop outwards and contact the sensor 343 under the thrust of the triggering block 332. The sensor 343 is used to detect the contact situation of the telescopic column 341 and transmit the signal to the control center. In this embodiment, the elastic component 342 uses a spring, and in practical applications, a shrapnel can also be used. The sensor 343 can be a proximity switch, a photoelectric sensor, an infrared sensor, etc.

[0026] During installation, the base 1 is horizontally fixed on the ground, and the position of the monitoring device 3 on the support rod 2 is adjusted so that the bottom of the detection cylinder 31 presses tightly on the dam 4; at this time, the bottom of the lifting column 331 retracts into the detection cylinder 31 under the supporting force of the dam 4; when the dam 4 settles, the dam 4 descends, and the lifting column 331 also slides downwards under the action of gravity or external force. When it slides a certain distance, the triggering block 332 contacts the telescopic column 341 and pushes it outwards to contact the sensor 343. When the sensor 343 senses the contact signal, it means that the settlement value of the dam 4 has exceeded the preset range, so the signal is transmitted to the control center, and the control center arranges personnel to handle it to avoid accidents.

[0027] In order to improve the sensitivity of the lifting column 331, a cover 313 is detachably installed above the detection cylinder 31, and a compression spring 333 is provided between the cover 313 and the top of the lifting column 331.

[0028] In order to ensure that the lifting column 331 has a higher vertical sliding position accuracy in the central channel 311, a limit block 334 is provided at the top of the lifting column 331. The limit block 334 is slidably mounted up and down in the central channel 311. A central hole is provided at the bottom of the central channel 311, and the diameter of the central hole is the same as that of the lifting column 331. The lifting column 331 passes through the central hole. By guiding the upper and lower parts of the lifting column 331, the vertical sliding position accuracy of the lifting column 331 is higher, avoiding the situation of shaking and jamming.

[0029] In order to adjust the preset range of the settlement value, the trigger block 332 with adjustable position is installed on the lifting column 331. The trigger block 332 can be fixed on the lifting column 331 by screws. In order to make the adjustment more convenient, scale marks for adjusting the position of the trigger block 332 are provided on the lifting column 331. By adjusting the position of the trigger block 332, the vertical distance between it and the telescopic column 341 is adjusted, thereby adjusting the preset range of the settlement.

[0030] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
