Description

Technical Field

[0001] The invention relates to the technical field of laser measuring instruments, and in particular to a stable laser displacement measuring instrument. Background Art

[0002] Laser displacement meter is a precision measuring instrument that uses laser beam as a medium to measure the displacement of the object being measured. It can measure the displacement change of the object in a non-contact manner. The working principle of laser displacement meter is usually based on two methods: one is to calculate the displacement change by the time it takes for the laser beam to be reflected back, and the other is to calculate the displacement change by measuring the phase difference between the emitted laser and the reflected laser.

[0003] When using a laser displacement meter to monitor the displacement of the ground or buildings during an earthquake, the laser displacement meter needs to be fixed for a long time in the area that needs to be monitored. Since the laser displacement meter is placed outdoors for a long time, it is inevitable to encounter windy and rainy weather. When encountering windy and rainy weather, the wind and rain will cause a large amount of rainwater to adhere to the lens of the laser transmitter, causing the laser emitted by the laser transmitter to diverge due to the influence of the attached rainwater, which will affect the monitored values.

[0026] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the hydraulic transmission assembly includes two n-shaped frames 901 symmetrically distributed front and back, the two n-shaped frames 901 are fixed to the left front side of the upper surface of the mounting frame 2, the upper sides of the two n-shaped frames 901 are slidably connected with a water collecting member 902, the water collecting member 902 is composed of a water collecting cylinder on the upper side, two sliding rods on the lower side and a drainage pipe fixedly connected and connected to the lower side of the water collecting cylinder, the sliding rod of the water collecting member 902 is slidably connected with the adjacent n-shaped frames 901, the drainage pipe of the water collecting member 902 is used to discharge the rainwater collected therein, and a spring is fixedly connected between the lower end of the sliding rod of the water collecting member 902 and the mounting frame 2, and the spring is used to drive the water collecting member 902 after moving Part 902 is reset, the left side of the rear n-shaped frame 901 is rotatably connected to the transmission shaft 903, the lower side of the water collecting cylinder of the water collecting part 902 is fixedly connected to the first rack 904, the left side of the front part of the sliding frame 802 is fixedly connected to the second rack 905, both ends of the transmission shaft 903 are fixedly connected to gears, the first rack 904 is meshed with the gear at the front end of the transmission shaft 903, the second rack 905 is meshed with the gear at the rear end of the transmission shaft 903, the position of the sliding frame 802 is controlled by the real-time monitoring of the rainfall by the water collecting part 902, and a focusing assembly is arranged on the rear side of the n-shaped frame 901, and the focusing assembly is used to improve the focusing intensity of the laser emitted by the laser emitter 3.

[0027] like Figure 8-Figure 10 As shown, the focusing assembly includes a first hydraulic telescopic rod 1001, which is fixed to the right part of the rear n-shaped frame 901 through a fixing plate, and the telescopic end of the first hydraulic telescopic rod 1001 is fixed to the second rack 905 through a connecting plate, and the mounting frame 2 is fixed with the second hydraulic telescopic rod 1002, and the fixing part of the first hydraulic telescopic rod 1001 and the fixing part of the second hydraulic telescopic rod 1002 are connected through a pipeline, and the fixing part of the first hydraulic telescopic rod 1001 and the second hydraulic telescopic rod 1002 are connected.

When the tray 1003 drives the convex lens 1004 to slide to the right, When moving, it first contacts with the horizontal guiding surface on the lower side of the limit block 1005 to prevent the second fixing frame 6 from releasing the limit of the convex lens 1004, and the coil spring directly drives the convex lens 1004 to pop out. Then the convex lens 1004 contacts and moves with the arc surface on the lower right side of the limit block 1005, so that the convex lens 1004 is slowly lifted, and finally contacts with the vertical surface on the right side of the limit block 1005, so that the convex lens 1004 is in a vertical state, thereby preventing the convex lens 1004 from causing damage to the lens of the laser emitter 3.

[0028] like Figure 1 , Fig.11 and Fig.12As shown, the fixing assembly includes a first L-shaped rod 1101, the first L-shaped rod 1101 is fixedly connected to the first rack 904, a third hydraulic telescopic rod 1102 is fixedly connected to the upper side of the left front portion of the mounting plate 1, the telescopic end of the third hydraulic telescopic rod 1102 is fixedly connected to the lower side of the first L-shaped rod 1101, and three brackets 1103 evenly distributed in the circumferential direction are fixedly connected to the lower side of the mounting plate 1, and the lower sides of the three brackets 1103 are all fixedly connected to a fixing cylinder 1104, and the lower side of the fixing cylinder 1104 is fixedly connected to a support plate 1105, and the support plate 1105 is used for After the fixing is completed, it fits the ground to provide support force. A cone cylinder 1106 is fixedly connected to the middle of the support plate 1105. A fourth hydraulic telescopic rod 1107 is fixedly connected to the upper part of the fixed cylinder 1104. The fixed parts of the three fourth hydraulic telescopic rods 1107 evenly distributed in the circumference are commonly connected with a pipeline, which is a four-way pipe. A through hole is set on the upper side of the fixed cylinder 1104. The pipeline passes through the through holes on the upper sides of the three fixed cylinders 1104 and is connected with the fixed part of the third hydraulic telescopic rod 1102. The fixed part of the third hydraulic telescopic rod 1102 , the fixed parts of the three fourth hydraulic telescopic rods 1107 and the pipes therebetween are filled with hydraulic oil, the telescopic end of the fourth hydraulic telescopic rod 1107 is fixedly connected with a truncated cone block 1108, the diameter of the truncated cone block 1108 gradually decreases from top to bottom, a plurality of circular holes evenly distributed circumferentially are provided on the cone cylinder 1106, the circular holes evenly distributed circumferentially on the cone cylinder 1106 are all slidably connected with the first plug rod 1109, the first plug rod 1109 is squeezed and matched with the adjacent truncated cone block 1108, and the truncated cone block 1108 is squeezed when it moves downward. The first plug rod 1109 is inserted into the soil to improve the fixing strength of the device in rainy days. The end of the first plug rod 1109 facing the inner side of the fixing tube 1104 is set to a spherical surface, so that when it is squeezed by the truncated cone block 1108, the friction on the inclined surface of the truncated cone block 1108 is reduced. A spring is fixed between the first plug rod 1109 and the adjacent conical tube 1106. When the truncated cone block 1108 moves upward and no longer squeezes the first plug rod 1109 evenly distributed circumferentially, the first plug rod 1109 slides inward to complete the reset.

[0029] like Fig.12 As shown, the middle part of the fixed cylinder 1104 is provided with symmetrically distributed sliding grooves, and the second L-shaped rod 1110 is slidably connected in the symmetrically distributed sliding grooves in the middle part of the fixed cylinder 1104. The second L-shaped rod 1110 is fixedly connected to the middle part of the telescopic part of the adjacent fourth hydraulic telescopic rod 1107, and the lower ends of the two second L-shaped rods 1110 are rotatably connected to the second plug rod 1111, and the support plate 1105 is provided with two symmetrically distributed inclined sliding grooves. The second plug rod 1111 is slidably matched with the adjacent inclined sliding grooves on the adjacent support plate 1105, so that the second plug rod 1111 can rotate when under pressure, so as to better enter the ground and improve the fixing strength of the device on rainy days.

[0030] When using the device to monitor the settlement degree of a building, the staff transports the device to the place to be monitored, places the device on the ground, and then pushes the three support plates 1105 downward. Taking one of the support plates 1105 as an example, when the support plate 1105 moves downward, it drives the cone 1106 and the two second insertion rods 1111 to move downward at the same time, so that the cone 1106 and the two second insertion rods 1111 are inserted into the soil until the lower side of the support plate 1105 contacts the ground, and stops pushing the support plate 1105. At this time, the fixing work is completed, and then the staff controls the control module installed in the mounting frame 2 to turn on the laser emitter 3 for monitoring.

[0031] If it rains during the monitoring process of the laser emitter 3, the first baffle 5 blocks the top of the emitting end of the laser emitter 3 to reduce the impact of rain on the emitting end of the laser emitter 3. The water collecting part 902 starts to collect rainwater, and its drain pipe starts to discharge rainwater outward. If the drainage speed of the drain pipe is greater than or equal to the collection speed of the water collecting part 902, the weight of the water collecting part 902 is not enough to move it downward, and the spring of the water collecting part 902 will not shrink. If the drainage speed of the drain pipe is less than the collection speed of the water collecting part 902, the water collecting part 902 will not shrink. The weight of 02 will continue to increase until it overcomes the elastic force of its spring, causing the water collecting member 902 to move downward and squeeze its spring. The water collecting member 902 drives the first rack 904 to move downward, and the first rack 904 drives the transmission shaft 903 to rotate through the adjacent gear on the transmission shaft 903. The transmission shaft 903 drives the second rack 905 to move rightward through the gear on its rear side, causing the sliding frame 802 and its accessory parts to move rightward, and then causing the second baffle 7 to move rightward along the second fixed frame 6 and the first fixed frame 4, thereby enhancing the shielding effect against rainwater.

[0032] When the second rack 905 moves to the right, the connecting plate of the second rack 905 squeezes the telescopic end of the first hydraulic telescopic rod 1001, and squeezes the liquid in the fixed part of the first hydraulic telescopic rod 1001 into the fixed part of the second hydraulic telescopic rod 1002. The telescopic end of the second hydraulic telescopic rod 1002 moves to the right due to the liquid squeezing and drives the tray 1003 and the convex lens 1004 to slide to the right along the slide groove of the second fixed frame 6. In the process of the convex lens 1004 moving to the right, the convex lens 1004 is always in contact with the guiding surface of the limit block 1005. When the convex lens 1004 moves to the right until it is no longer affected by the second fixed frame, the convex lens 1004 is in contact with the guiding surface of the limit block 1005. When the slide slot of the fixed frame 6 is limited, the convex lens 1004 rotates counterclockwise (from front to back) driven by the coil spring. During the counterclockwise rotation of the convex lens 1004, the arc surface on the right side of the limit block 1005 guides the convex lens 1004 to make the convex lens 1004 rotate slowly to prevent it from being quickly ejected due to the force of the coil spring and causing damage to itself and the lens of the laser emitter 3. Finally, the right side of the limit block 1005 vertically limits the convex lens 1004 to keep it in a vertical state, thereby achieving the effect of improving the focusing intensity of the lens of the laser emitter 3 in rainy weather.

[0033] During the downward movement of the first rack 904, the first rack 904 drives the first L-shaped rod 1101 to move downward, and the first L-shaped rod 1101 drives the telescopic end of the third hydraulic telescopic rod 1102 to move downward, squeezing the liquid in the fixed part of the third hydraulic telescopic rod 1102 into the fixed parts of the three fourth hydraulic telescopic rods 1107, so that the telescopic ends of the fourth hydraulic telescopic rods 1107 extend. Taking the movement of the telescopic ends of one of the fourth hydraulic telescopic rods 1107 as an example, the telescopic end of the fourth hydraulic telescopic rod 1107 drives the truncated cone block 1108 to move downward, and the truncated cone block 1108 squeezes the first insertion rod 1109 evenly distributed circumferentially. The first insertion rod 1109 slides outward to squeeze the adjacent springs and is inserted into the ground.

[0034] When the telescopic portion of the fourth hydraulic telescopic rod 1107 moves downward, the telescopic portion of the fourth hydraulic telescopic rod 1107 drives the two adjacent second L-shaped rods 1110 to move downward together, and the second L-shaped rod 1110 drives the adjacent second insertion rod 1111 to move downward, while the second insertion rod 1111 is rotated under the guidance of the adjacent inclined groove on the adjacent support plate 1105 to drill into the soil. Through the outward extension of the first insertion rod 1109 and the downward movement of the second insertion rod 1111, the mutual cooperation of horizontal fixation and longitudinal fixation can enhance the fixing effect of the device and prevent the device from tipping over due to loose soil in rainy days.

[0035] When the device encounters windy and rainy weather during use, the wind vane 805 drives the wind collecting member 804 to rotate to face the windward side under the influence of wind force, and the wind collecting member 804 drives the rotating ring 807 to rotate through the transmission between the first transmission disk 809 and the circumferentially evenly distributed toggle rod 808, and the rotating ring 807 drives the second baffle plate 7 to rotate through the circumferentially evenly distributed air guide 810, so that the second baffle plate 7 blocks the wind and rain, reducing the influence of rain driven by wind on the lens of the laser emitter 3, so that the laser emitter 3 can still be used normally in windy and rainy weather.

[0036] When the wind collecting member 804 faces the windward side, the wind enters the first cavity of the wind collecting member 804, and enters the second cavity of the rotating sleeve 803 through the ventilation holes uniformly distributed circumferentially on the wind collecting member 804. The rainwater brought into the first cavity of the wind collecting member 804 by the wind falls to the lower side of the first cavity of the wind collecting member 804 and flows out through the through holes on the lower side thereof. The wind in the second cavity of the rotating sleeve 803 enters the third cavity of the rotating ring 807 through the pipeline, and flows into the fourth cavity of the second baffle 7 through the circumferentially uniformly distributed air duct 810. Finally, the wind flows out through the uniformly distributed through holes on the second baffle 7, blowing off the dust and rainwater on the lens of the laser emitter 3. By utilizing the arrangement of the through holes on the second baffle 7, the dust and rainwater on the lens of the laser emitter 3 can be moved in the same direction, thereby improving the cleaning coverage while avoiding the influence of turbulence on the cleaning effect.

[0037] When the rain stops, the water in the water collecting part 902 is gradually discharged from the drain pipe, the weight of the water collecting part 902 is gradually reduced, the spring gradually overcomes the weight of the water collecting part 902, and drives the water collecting part 902 to move upward, and the upward movement of the water collecting part 902 drives the first rack 904 to move upward, and the first rack 904 drives the second rack 905 to move leftward through the transmission shaft 903 and the two gears thereon, so that the sliding frame 802 drives the attached parts thereon to move leftward, and then drives the second baffle plate 7 to move leftward along the slide grooves of the second fixed frame 6 and the first fixed frame 4, completing the resetting of the second baffle plate 7, and at the same time, the first rack 904 moves upward and drives the first L-shaped rod 1101 to move upward, and the first L-shaped rod 1101 drives the telescopic end of the third hydraulic telescopic rod 1102 to move upward, and the three fourth hydraulic telescopic rods 1102 are moved upward. The liquid in the fixed part of the rod 1107 is drawn back to the fixed part of the third hydraulic telescopic rod 1102, so that the telescopic end of the fourth hydraulic telescopic rod 1107 moves upward, and the upward movement of the telescopic end of the fourth hydraulic telescopic rod 1107 drives the adjacent truncated cone block 1108 to move upward, and the upward movement of the truncated cone block 1108 releases the squeezing of the adjacent and circumferentially evenly distributed first plug rod 1109, so that the first plug rod 1109 slides inwardly under the action of the spring force, completing the resetting of the first plug rod 1109, and the upward movement of the telescopic part of the fourth hydraulic telescopic rod 1107 drives the two adjacent second L-shaped rods 1110 to move upward, and while the two second L-shaped rods 1110 move upward, the second plug rod 1111 rotates under the guidance of the adjacent inclined grooves on the adjacent support plate 1105, and moves upward out of the soil, completing the resetting of the second plug rod 1111.

[0038] When the device is no longer in use and needs to be recycled, the staff needs to stop the operation of the laser emitter 3 through the installation module set on the mounting frame 2, and then pull up the three fixed cylinders 1104 evenly distributed circumferentially until the cone cylinder 1106 completely leaves the ground, thereby completing the recycling of the device.

[0039] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 7 and Fig.13As shown, it also includes a center of gravity adjustment component, which is arranged on the mounting frame 2. The center of gravity adjustment component is used to change the center of gravity position. The center of gravity adjustment component includes a sliding block 1201, which is slidably connected to the mounting frame 2, and the sliding block 1201 is fixedly connected to the fixing ring 806. The left part of the upper side of the sliding block 1201 is rotatably connected to the second transmission disk 1202, and the second transmission disk 1202 is provided with a plurality of grooves evenly distributed in the circumferential direction. The grooves of the second transmission disk 1202 are squeezed and matched with the adjacent toggle rods 808, so that when the rotating ring 807 rotates, the toggle rods 808 evenly distributed in the circumferential direction are used to adjust the center of gravity. 08 The grooves uniformly distributed circumferentially on the second transmission disk 1202 are squeezed to drive the second transmission disk 1202 to rotate, and the lower side of the mounting plate 1 is rotatably connected to the turntable 1203. A connecting rope is wound around the second transmission disk 1202 and the turntable 1203. The connecting rope is set to be an elastic connecting rope to ensure that the sliding block 1201 can still transmit normally after sliding. The left sides of the mounting plate 1 and the mounting frame 2 are fixedly connected with guide wheels symmetrically distributed front and back to support the elastic rope. A counterweight block 1204 is fixedly connected to the eccentric part of the turntable 1203, and the counterweight block 1204 is located on the windward side of the turntable 1203.

[0040] When the rotating ring 807 rotates, the rotating ring 807 drives the second transmission disk 1202 to rotate through the circumferentially evenly distributed toggle rods 808, the second transmission disk 1202 drives the turntable 1203 to rotate through the connecting rope, the turntable 1203 drives the counterweight block 1204 to rotate, so that the counterweight block 1204 rotates to the windward side of the turntable 1203 to adjust the center of gravity of the device, thereby enhancing the stability of the mounting frame 2 and its accessories.

[0041] When the fixed ring 806 slides to the right, the fixed ring 806 drives the sliding block 1201 to slide to the right, so that the connecting rope wound between the second transmission disk 1202 and the rotating disk 1203 is stretched, thereby enhancing the friction between the elastic connecting rope and the transmission disk when it rains, ensuring that the second transmission disk 1202 can drive the rotating disk 1203 to rotate, and when the fixed ring 806 moves to the left to reset, the fixed ring 806 drives the sliding block 1201 to reset, so that the connecting rope shrinks.

[0042] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
