Description

TECHNICAL FIELD

[0001] The application relates to the technical field of water conservancy engineering monitoring, in particular to a dam deformation monitoring device capable of prolonging service life. BACKGROUND

[0002] As an important water conservancy engineering hub, a reservoir dam shoulders the heavy responsibilities of water storage, flood control, irrigation, power generation, drinking water for people and livestock, flood prevention and flood control scheduling, etc. During the operation process of the reservoir dam, very complex loads are borne, and the reservoir dam is also affected by various factors such as heavy rainfall, which leads to a very large safety hazard. Therefore, a reservoir dam safety monitoring system needs to be established to monitor the operation conditions such as dam displacement, seepage and seepage pressure in real time, so as to ensure the safe operation of the dam.

[0003] In the related art, deformation monitoring is generally performed by arranging GNSS monitoring devices on the dam slope body, acquiring three-dimensional coordinate information of the dam structure in real time, and setting a signal base station on the shore to monitor the distance between the GNSS monitoring devices in real time. The displacement and deformation of the dam can be accurately measured to achieve the purpose of monitoring the deformation of the dam. During the operation of the GNSS monitoring device, on the one hand, in order to better adapt to the outdoor working environment, the protective cover at the top needs to maintain good sealing effect, but at the same time, the heat dissipation performance of the protective cover is weakened. The GNSS equipment generates a certain amount of heat during operation. If the heat dissipation performance of the protective cover is poor, the heat cannot be dissipated in time, which may cause the temperature inside the equipment to rise. The high temperature may affect the performance and service life of the equipment, and even cause the equipment to start the overheat protection mechanism, so that the equipment temporarily stops working and affects normal use. On the other hand, the GNSS monitoring device is generally provided with working power by a photovoltaic system, but the long-term outdoor working environment often causes dust and impurities to accumulate on the photovoltaic panel, which not only affects the power generation efficiency of the photovoltaic system, but also affects the service life of the photovoltaic panel.

[0010] In one alternative embodiment, the driving component includes a first transverse lead screw, a second transverse lead screw, a sliding lead screw, and a rotary motor. The first transverse lead screw and the second transverse lead screw are disposed on opposite sides of the photovoltaic panel. The two ends of the sliding lead screw are slidably connected to the first transverse lead screw and the second transverse lead screw respectively via sliders.

[0011] In one alternative embodiment, the nozzle is movably connected to the water outlet pipe and can rotate relative to the water outlet pipe by a preset angle. The nozzle is in a water spraying state, in which the water sprayed by the nozzle can completely cover the photovoltaic panel.

[0012] In one alternative embodiment, a support plate is fixedly mounted on the top of the mounting bracket, and the water storage tank is fixedly connected to the support plate.

[0015] In one alternative embodiment, the mounting bracket is made of stainless steel, and the protective cover is made of polycarbonate; the photovoltaic panel is electrically connected to the water circulation mechanism and the cleaning mechanism respectively, and is powered by them.

[0016] The beneficial effects of this application are as follows:

[0029] As Figures 1-3As shown, the dam deformation monitoring device provided by the embodiment of the application has a long service life, and comprises a monitoring device body 1, a water circulation mechanism 2 and a cleaning mechanism 3. The monitoring device body 1 comprises a mounting bracket 11, a photovoltaic panel 12 and a GNSS monitoring device 13. The photovoltaic panel 12 is located on the side of the mounting bracket 11, and the GNSS monitoring device 13 is located on the top of the mounting bracket 11. The GNSS monitoring device 13 is provided with a protective cover 14 having a water storage cavity 141. The water circulation mechanism 2 comprises a water storage tank 21, a water pump 22, a first circulating water pipe 23 and a second circulating water pipe 24. The water storage tank 21 is arranged at the bottom of the GNSS monitoring device 13. The first circulating water pipe 23 and the second circulating water pipe 24 are respectively connected to the water storage tank 21 and the water storage cavity 141. The pipe diameter of the first circulating water pipe 23 is much larger than that of the second circulating water pipe 24. The water pump 22 is arranged in the first circulating water pipe 23 and is used to pump the water in the water storage tank 21 into the water storage cavity 141 through the first circulating water pipe 23. The cleaning mechanism 3 is configured to clean the surface of the photovoltaic panel 12 by using the water in the water storage tank 21.

[0030] The dam deformation monitoring device in the embodiment can realize the periodic circulation of water between the water storage tank 21 and the water storage cavity 141 by the water pump 22, the first circulating water pipe 23 and the second circulating water pipe 24. Since the pipe diameter of the first circulating water pipe 23 is much larger than that of the second circulating water pipe 24, a certain amount of water can be retained in the water storage cavity 141. By using the good heat transfer property of water, sufficient heat exchange with the heat energy generated by the GNSS module in the protective cover 14 can be realized, so as to achieve the purpose of heat dissipation of the GNSS monitoring device 13. In addition, the cleaning mechanism 3 can clean the surface of the photovoltaic panel 12 by using the water in the water storage tank 21, so as to reduce the dust and impurities on the photovoltaic panel 12, ensure the power generation efficiency of the photovoltaic panel 12, and improve the overall service life.

[0031] As Figures 1-2As shown, in one specific embodiment, the number of photovoltaic panels 12 is at least two. For example, in this embodiment, the number of photovoltaic panels 12 is two. Of course, other preset numbers can be made according to actual needs, which are not specifically limited here. The number of cleaning mechanisms 3 corresponds to the number of photovoltaic panels 12. The photovoltaic panels 12 are electrically connected to the devices that require electricity in the water circulation mechanism 2 and the cleaning mechanism 3, and are supplied with power. The cleaning mechanism 3 includes a water outlet pipe 31, a driving component, and a brush 32. The water outlet pipe 31 is connected to the water storage tank 21, and a nozzle 33 is provided at the opening of the water outlet pipe 31. The driving component is located on the side of the photovoltaic panel 12 and is drivenly connected to the brush 32 and can drive the brush 32 to move. The movement of the brush 32 includes rotation and movement along the length and width directions of the photovoltaic panel 12. In addition, the nozzle 33 is movably connected to the water outlet pipe 31 and can rotate relative to the water outlet pipe 31 at a preset angle. The nozzle 33 has a water spraying state. When spraying water, the water sprayed by the nozzle 33 can completely cover the photovoltaic panel 12. The sprayed water can better clean the photovoltaic panel 12.

[0032] like Figures 1-2 As shown, in one specific embodiment, the driving component includes a first transverse lead screw 34, a second transverse lead screw 35, a sliding lead screw 36, and a rotary motor 38. The first transverse lead screw 34 and the second transverse lead screw 35 are disposed on opposite sides of the photovoltaic panel 12. The two ends of the sliding lead screw 36 are slidably connected to the first transverse lead screw 34 and the second transverse lead screw 35 respectively via sliders 37. The rotary motor 38 is movably connected to the sliding lead screw 36 and can drive the brush 32 to rotate. In addition, the driving component also includes other driving devices, such as motors or cylinders, for driving the first transverse lead screw 34 or the second transverse lead screw 35 to rotate and for driving the rotary motor 38 to move relative to the sliding lead screw 36. The first transverse lead screw 34 can be rotated by a motor, and the rotary motor 38 can be moved relative to the sliding lead screw 36 by a cylinder. Since such movement can be achieved by various driving devices commonly used in the art, they will not be elaborated upon here. As long as the rotation of the brush 32 and its movement along the length and width of the photovoltaic panel 12 can be accomplished, it is sufficient.

[0033] like Figures 1-3As shown, in a specific embodiment, the top of the mounting bracket 11 is fixedly provided with a support plate 15, and the water storage tank 21 is fixedly connected with the support plate 15. The water storage tank 21 is a cylindrical tube, the inner diameter of the water storage tank 21 is greater than the outer diameter of the mounting bracket 11, and the outer diameter of the water storage tank 21 is less than the outer diameter of the support plate 15, so that the load of the water storage tank 21 can be uniformly transmitted to the ground by the mounting bracket 11. The top of the water storage tank 21 is provided with a water inlet to facilitate the replenishment of pure water to the water storage tank 21 in the later period. In addition, the bottom of the support plate 15 is provided with a plurality of inclined braces 16, for example, in this embodiment, the number of inclined braces 16 is 4, and the 4 inclined braces 16 are connected with the support plate 15 and the mounting bracket 11 respectively, so as to improve the strength and stability of the connection; the bottom of the mounting bracket 11 is provided with a base 17, and the sidewall of the mounting bracket 11 is provided with a main control machine box 18.

[0034] As shown, Figures 1-2 In a specific embodiment, the photovoltaic panel 12 is connected with the mounting bracket 11 through the connecting rod 4, the end of the connecting rod 4 is provided with a hoop 41, and the hoop 41 is tightly arranged on the mounting bracket 11 through the screw rod 42 and the nut 43. The mounting bracket 11 and the base 17 are both made of stainless steel material, and the protective cover 14 is made of polycarbonate material; polycarbonate has the characteristics of high wave permeability, high temperature resistance and corrosion resistance, which can ensure the smoothness of the antenna signal and protect the equipment from damage from the external environment.

[0035] The working principle of the dam deformation monitoring device in the embodiment of the application is as follows: after the construction of the reservoir dam is completed, the monitoring device is arranged according to the monitoring scheme. According to the size of the water storage tank 21, pure water is supplemented through the water inlet regularly, and in this embodiment, the staff is arranged to supplement pure water to the water storage tank 21 every month, and the monitoring device is comprehensively checked at the same time. If damage or failure is found, it should be repaired in time.

[0036] When the monitoring device works, the GNSS monitoring device 13 generates a certain amount of heat during operation, and the airtightness of the protective cover 14 causes the heat to be unable to be discharged in time. However, under the drive of the water pump 22, the water in the water storage tank 21 flows into the water storage cavity 141 of the protective cover 14 through the first circulating water pipe 23. Since the pipe diameter of the first circulating water pipe 23 is much larger than that of the second circulating water pipe 24, the water will first fill the entire water storage cavity 141, and then slowly flow back to the water storage tank 21 through the second circulating water pipe 24. In this process, by utilizing the good heat transfer property of water, sufficient heat exchange with the heat energy generated by the GNSS monitoring device 13 in the protective cover 14 can be achieved, so as to achieve the purpose of heat dissipation of the GNSS monitoring device 13.

[0037] In addition, the photovoltaic panel 12 often accumulates dust and impurities, even stubborn stains such as bird droppings, when working in the wild. Through the sliding block, sliding screw 36 and other components in the cleaning mechanism 3, the brush 32 can be moved horizontally along the photovoltaic panel 12. Through the rotating motor 38 and other driving components, the brush 32 is rotated and moved vertically along the photovoltaic panel 12, achieving full coverage of the brush 32 on the photovoltaic panel 12. At the same time, the water tank 21 is provided with a water outlet pipe 31 and a nozzle 33 below, which can regularly spray water to the entire photovoltaic panel 12 according to the working frequency of the brush 32. The two work together to effectively remove stubborn stains, and have strong engineering implementability.

[0038] The above is only the preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
