Description

Technical Field

[0001] The invention belongs to the technical field of surveying and mapping instruments, and in particular relates to a high-steepness measuring device for a pumped-storage power station. Background Art

[0002] Pumped-storage power stations are important engineering facilities that meet the development and utilization of new energy at present and in the future. Most pumped-storage power stations are built in high mountains. Temporary access roads need to be opened in the early stage of construction. Since the slag formed by the excavation of the access roads in the early stage cannot be transported out, blasting and excavation will cause slag hanging on some high and steep slopes. In order to control the slag hanging on the slopes, it is necessary to conduct a comprehensive measurement of the slag hanging on the slopes through surveying and mapping instruments, so as to facilitate the subsequent adoption of appropriate control plans.

[0003] At present, the total station is one of the commonly used measuring instruments for measuring the slag hanging on the high and steep slopes. The total station is a high-precision measuring instrument integrating optics, machinery and electricity. It can quickly and accurately measure the slag hanging on the high and steep slopes. It is relatively convenient to use. For example, a dam slope measurement total station disclosed in patent announcement number CN221404300U; Before using the total station, it needs to go through leveling, calibration and other operations before it can carry out measurement work to ensure the accuracy of the measurement results. In the management of high and steep slopes, since most pumped storage stations are built in high mountains and are affected by the unevenness of the high and steep slopes, irregular windflows are often generated at the foot of the slope. When the irregular windflow blows to the total station, it is easy to cause the total station to shake, resulting in a large deviation in the total station's detection results, affecting the subsequent mapping of slope slag. At the same time, due to the poor stability of the slope scraping, under the action of the windflow, the sand and dust at the slope slag are easy to float with the wind, and the diameter of the total station objective is large. When the sand and dust hit the total station objective with the windflow, it is easy to cause scratches and pitting on the surface of the total station objective. Summary of the invention

[0026] The operating principle of the present invention is now described as follows: a tripod is set up at a pre-selected point, and then the base 1 is installed on the tripod, and the frame 2 is leveled by the leveling structure on the base 1. Subsequently, the total station is calibrated according to the operating requirements. Then, the operator inputs the corresponding parameters to the control unit 4 through the control unit 3 according to the detection results of the temperature detector 151, the humidity detector 152 and the air pressure detector 153. Subsequently, the control unit 4 corrects the detection results according to the temperature, humidity and air pressure parameters to reduce the influence of different temperature, humidity and air pressure on the detection results. After all the preparations are ready, press the measurement button on the control unit 3; After the control unit 4 receives the electrical signal from the measuring button of the control unit 3, it will immediately control the air pump 114 to start working. At this time, the air pump 114 inhales external air through the three-way pipe 142 and the main air inlet 115, and transports the airflow to the inside of the air outlet cavity 112 through the air outlet end. Subsequently, the airflow is discharged into the air cover 121 through the main exhaust hole 122, and then the airflow is discharged through the air cover 121 and each heat dissipation aluminum tube 125. The heat generated by the operation of the control unit 3 and the control unit 4 will be conducted to the heat dissipation aluminum tube 125 through the heat conduction seat 126, and when the cold air passes through the heat dissipation aluminum tube 125, it will exchange heat with the heat dissipation aluminum tube 125, so that the heat at the heat dissipation aluminum tube 125 can be extracted, thereby achieving the effect of quickly dissipating the heat of the control unit 4 and the control unit 3; When the air pump 114 is started, the control unit 4 will synchronously control the spotlight 85. When the light emitted by the spotlight 85 is irradiated to the photoelectric switch 86, the photoelectric switch 86 will convert the optical signal into an electrical signal and output it to the control unit 4. If during the measurement, the irregular wind flow at the slope blows to the frame 2, the wind flow will blow the cross-shaped hanging plate 84 to deflect to one side. At this time, the spotlight 85 on the top of the sphere 82 will also deflect synchronously. When the wind force is strong enough (the wind force is usually greater than 4 meters per second), the deflection angle of the cross-shaped hanging plate 84 to one side is too large. At this time, the misalignment angle between the spotlight 85 and the photoelectric switch 86 is too large, so the light emitted by the spotlight 85 cannot irradiate the photoelectric switch 86. Since the photoelectric switch 86 loses the light irradiation, the photoelectric switch 86 The electrical signal output by the switch 86 to the control unit 4 will also disappear synchronously. At this time, the control unit 4 will immediately control the first normally closed solenoid valve 124 inside the air outlet pipe 116 and the second normally closed solenoid valve 146 inside the three-way pipe 142 to be powered on and opened, and control the second normally open solenoid valve 145 inside the three-way pipe 142 and the first normally open solenoid valve 123 inside the main exhaust hole 122 to be powered on and closed. At the same time, the third normally closed solenoid valve 162 inside each auxiliary exhaust hole 161 is controlled to remain powered off and closed. At this time, the suction end of the air pump 114 will inhale the external air through the auxiliary air inlet hole 143, and the dust particles contained in the external air will be trapped by the dust filter 144, and the filtered airflow will be transported to the inside of the air outlet cavity 112 by the air pump 114 through the three-way pipe 142 Since the first normally open electromagnetic valve 123 is powered on and closed, and the third normally closed electromagnetic valve 162 remains powered off and closed, the airflow inside the air outlet cavity 112 enters the hollow ring 9 through the air outlet pipe 116 and the connecting hose 117, and is ejected through each jet hole 10. Since the airflow is ejected through the jet hole 10 (since the dust particles in the airflow do not directly contact the lens of the objective lens end 7 when the airflow is discharged through the heat dissipation aluminum tube 125, the lens of the objective lens end 7 will not be damaged. At this time, the airflow does not pass through the dust filter net 144, and will not cause damage to the dust filter net 144. When the airflow is ejected through the jet hole 10, the dust particles are intercepted and filtered by the dust filter net 144, which can prevent the ejected airflow from containing excessively large dust particles that cause damage to the objective lens end 7), and is affected by the objective lens end 7 The lens of the eyepiece end 6 is blocked, and the ejected airflow can only flow to the side away from the objective lens end 7, so it can resist the external wind flow blown to the objective lens end 7, so that an air film on one side can be formed on the surface of the objective lens end 7, and the lens of the objective lens end 7 is avoided to be directly in contact with the external wind flow as much as possible, so that the lens of the objective lens end 7 can be avoided to be directly damaged by dust particles as much as possible (because the aperture of the eyepiece end 6 is small and there are people blocking it here, the external wind flow is not easy to directly contact the lens of the eyepiece end 6, and it is not easy to damage the lens of the eyepiece end 6). At the same time, after the electrical signal output by the photoelectric switch 86 received by the control unit 4 disappears, the control unit 4 will control its own alarm module (such as a buzzer) to work, so as to remind the operator to re-perform the measurement work (wherein,After the electrical signal output by the photoelectric switch 86 to the control unit 4 disappears, the control unit 4 will control the airflow output by the air pump 114 to continue to be ejected through the air jet hole 10, and control its own alarm module to continue to work until the operator presses the reset button on the panel of the control unit 3, and the control unit 4 restarts the measurement work, that is, at this time the airflow will not be ejected through the air jet hole 10, and the alarm module will also stop working, so as to avoid the operator mistakenly believing that the measurement result is valid after the wind flow stops);, Secondly, after the control unit 4 receives the electrical signal of the measuring button of the control unit 3, it will synchronously control the driving motor 132 to work. The driving motor 132 can drive the cam 133 and the brush rod 147 to rotate. Every time the cam 133 rotates one circle, the end point of the cam 133 will squeeze the touch hemisphere 135 once, and when the touch hemisphere 135 is squeezed by the cam 133, it will close the moving contact of the pressure switch 134. At this time, the pressure switch 134 will output an electrical signal to the control unit 4, and the counting module of the control unit 4 will synchronously count once. When the counting module counts to the set value, the control unit 4 will display on the panel of the control unit 3 that the total station needs maintenance, and the operator needs to The total station needs to be maintained (for example, check whether the lenses at the eyepiece end 6 and the objective end 7 are sealed and aged, check whether the leveling structure is worn, etc., and eliminate possible problems in time). When the temperature, humidity and air pressure become higher, the maintenance interval of the total station also needs to be shortened accordingly. For example, high temperature will cause the seal at the lens to expand due to heat, which will affect the sealing of the lens. When the air pressure becomes high, the contact pressure between the lens and the seal will also change accordingly under the action of the air pressure, which may also cause the connection between the seal and the lens to loosen. When the humidity increases, the possibility of the lens surface being eroded by water vapor increases. When the temperature, humidity and air pressure become high, The strength of the electrical signals output by the temperature detector 151, the humidity detector 152 and the air pressure detector 153 to the control unit 4 will also increase accordingly. At this time, the control unit 4 controls the current passed into the first normally open solenoid valve 123 and the third normally closed solenoid valve 162 to increase accordingly. When the current passed into the first normally open solenoid valve 123 increases, the electromagnetic component inside it will generate a larger magnetic attraction, thereby attracting the opening degree of its own valve plate to decrease. When the current passed into the third normally closed solenoid valve 162 increases, the magnetic attraction generated by the electromagnetic component inside it increases, thereby attracting the opening degree of its own valve plate to increase. Therefore, the airflow entering the air outlet cavity 112 will be discharged more through the auxiliary exhaust hole 161, and At this time, the insulating sealing plate 163 is pushed toward the insulating sleeve 164 under the action of air pressure, and the displacement distance will also increase, thereby shortening the length of the resistor rod 166 connected to the connection circuit between the conductive ring 165 and the drive motor 132, so that the connection circuit resistance of the resistor rod 166, the conductive ring 165 and the drive motor 132 becomes smaller, thereby increasing the output power of the drive motor 132. At this time, the rotation speed of the cam 133 is relatively fast, so the frequency of the electrical signal output by the pressure switch 134 to the counting module of the control unit 4 will also increase accordingly, thereby speeding up the counting process of the counting module, shortening the time interval for maintenance of the total station accordingly, and ensuring the timeliness of maintenance of the total station.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
