Description

Technical Field

[0001] The utility model relates to the technical field of slope monitoring, and more specifically to an automatic monitoring and early warning device for slopes in reservoir operation management. Background Art

[0002] A reservoir is a man-made lake, while smaller ones are called ponds, dams, and impoundments. They are generally formed by building a dam in the middle or upper reaches of a river, flooding the valley. However, some reservoirs are built on the sea. Dams are generally built in narrow valleys because the hillsides on either side serve as natural walls, greatly shortening the dam's length.

[0003] At present, after the completion of the construction of a reservoir, in order to ensure the stability of the reservoir dam slope, GNSS slope monitoring and early warning devices are often used to complete the slope monitoring of the reservoir dam. During the monitoring process, the GNSS slope monitoring and early warning device is mostly placed on the top of the slope, which makes it impossible to synchronously monitor the slope and the slope protection system. The accuracy and sensitivity of the slope stability detection are relatively limited, which is not conducive to the operation and management of the reservoir. In view of this, we propose an automatic slope monitoring and early warning device for reservoir operation and management. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide an automatic monitoring and early warning device for the slope of reservoir operation and management, so as to solve the technical problems that the current slope monitoring and early warning devices are mostly installed on the top of the slope, cannot synchronously monitor the slope and the slope protection system of the slope, and the accuracy and sensitivity of the slope stability detection are relatively limited, which is not conducive to the operation and management of the reservoir.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: an automatic monitoring and early warning device for reservoir operation and management slopes, comprising a slope system arranged on the upper slope of a reservoir dam and composed of a plurality of slope protection components arranged in an array, and a monitoring and early warning component provided in each slope protection component for synchronously monitoring the upper slope of the reservoir dam and the slope system;

[0006] A concrete pouring layer is poured in the slope protection assembly, and the slope protection assembly includes a slope protection plate, a circular groove is opened at the center of the top of the slope protection plate, and a cylinder is fixedly arranged in the circular groove;

[0007] The monitoring and early warning component includes a column, the top of which is fixedly provided with a CNSS monitoring and early warning device, and the bottom of the column is constructed with a bent rod, and the bottom of the bent rod is constructed with a pin that passes through the cylinder and is inserted into the reservoir dam.

[0008] The utility model realizes synchronous detection of the slope and slope system on the reservoir dam through the slope system formed by several slope protection components arranged on the upper slope of the reservoir dam, in conjunction with the monitoring and early warning components, so that when the slope on the reservoir dam is abnormal or affects the slope system, the slope data can be obtained in time through the CNSS monitoring and early warning device on the column. Since the monitoring and early warning component is connected to the slope system formed by several slope protection components, slight abnormalities on the slope on the reservoir dam and the slope system will be promptly acquired by the CNSS monitoring and early warning device, which greatly improves the accuracy and sensitivity of slope stability monitoring and is beneficial to the reservoir operation and management.

[0009] Preferably, a groove is provided at the top of the slope protection plate, and the groove cooperates with the cylinder to form a casting trough for casting the concrete casting layer.

[0010] Preferably, a positioning plate is centrally constructed at the lower end of the slope protection plate, and a positioning groove for inserting the positioning plate is centrally opened at the upper end of the slope protection plate.

[0011] Preferably, a plurality of through holes are equidistantly provided on the high side of the bottom end of the casting trough, and ground nails are provided in the through holes to pass through the positioning plate and be inserted into the reservoir dam.

[0012] Preferably, a sleeve is constructed on the outer edge surface of the bent rod, and the sleeve is sleeved on the cylinder.

[0013] Preferably, the bottom end of the outer edge surface of the sleeve is configured with a plurality of extension ears in a circular array, and the extension ears are plugged into the casting trough, and fixing bolts threadedly connected to the slope protection plate are movably provided in the extension ears.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model realizes synchronous detection of the upper slope of the reservoir dam and the slope system by cooperating with the monitoring and early warning component through the slope system formed by several slope protection components arranged on the upper slope of the reservoir dam. When the upper slope of the reservoir dam is abnormal or affects the slope system, the slope data can be obtained in time through the CNSS monitoring and early warning device on the column. Since the monitoring and early warning component is connected to the slope system formed by several slope protection components, slight abnormalities in the upper slope of the reservoir dam and the slope system will be promptly detected by the CNSS monitoring and early warning device, which greatly improves the accuracy and sensitivity of slope stability monitoring and is beneficial to the operation and management of the reservoir.

[0016] 2. The present invention also forms a slope protection system for the upper slope of the reservoir dam through a plurality of slope protection components. During the arrangement, three ground nails are passed through the slope protection plate and inserted into the reservoir dam, and another slope protection plate is arranged in sequence, so that the positioning plate on the previous slope protection plate is inserted into the positioning groove on the other slope protection plate, and the three ground nails are again passed through the slope protection plate and the positioning plate and inserted into the reservoir dam, and the arrangement is carried out in sequence, thereby realizing the arrangement of the slope system, so that a plurality of slope protection components are arranged jointly in the longitudinal direction, so that the monitoring and early warning components arranged on the slope protection components can monitor the stability of the upper slope of the reservoir dam in real time, thereby further improving the detection effect of the slope stability.
