Description

Technical Field

[0001] This utility model relates to the field of surveying instrument and equipment technology, specifically to a self-cleaning device for a total station reflector used for building deformation monitoring. Background Technology

[0002] A self-cleaning device for the reflector of a total station used in building deformation monitoring is a device designed to ensure the cleanliness of the reflector and improve measurement accuracy during such monitoring. It is primarily used in scenarios requiring total station deformation monitoring, such as building construction, tunnel engineering, and slope monitoring. In these scenarios, the reflector is easily contaminated by dust and dirt, affecting measurement accuracy. This device can automatically or semi-automatically clean the reflector, ensuring accurate and efficient measurement work.

[0003] In building deformation monitoring, total stations rely on reflectors to receive and reflect laser signals for accurate measurements. The reflector lenses, as key components for signal transmission, are prone to accumulating dust, sand, and other impurities when exposed to outdoor environments. Current technologies largely depend on manual, periodic lens cleaning. This requires personnel to travel to the monitoring point, which is time-consuming, labor-intensive, and difficult to address sudden dust accumulation. Improper wiping can also damage the lens surface. Some simple cleaning devices only blow from one direction, creating blind spots and resulting in poor cleaning effectiveness due to dispersed airflow. If dust accumulation on the lenses is not cleaned promptly, it interferes with the normal reflection of laser signals, affecting the total station's measurement accuracy and failing to meet the requirements for data accuracy and timeliness in building deformation monitoring. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning device for the reflector of a total station used for building deformation monitoring, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a self-cleaning device for a total station reflector used for building deformation monitoring, including a detector body. A ring is fixedly installed on the detector body. The interior of the ring is hollow. An angle adjustment device is provided on the inner wall of the ring. A corrugated pipe is provided on the angle adjustment device. A first air outlet pipe is installed at the other end of the corrugated pipe. A dust removal fan is provided on one side of the detector body. The air outlet of the dust removal fan is connected to multiple first air outlet pipes.

[0006] Furthermore, the first air outlet duct is provided with a spiral component inside, and a support column is provided on the spiral component. The support column is provided with a spiral protrusion inside. Multiple fixing rods are fixedly installed between the first air outlet duct and the spiral component, and the fixing rods are cylindrical.

[0007] Furthermore, an outward-curving guide is provided at the end of the first air outlet duct that is away from the angle adjustment device.

[0008] Furthermore, an air outlet pipe is fixedly installed at the bottom of the dust removal fan, and the other end of the air outlet pipe is fixedly installed on a circular ring.

[0009] Furthermore, a dust sensor is provided on the inner wall of the ring, and the dust sensor is communicatively connected to an external controller; the dust removal fan is also communicatively connected to the controller.

[0010] Furthermore, the detector body is provided with a lens, which is located at the center of the ring.

[0011] Furthermore, multiple angle adjustment devices and first air outlet pipes are configured, and the angle adjustment devices and first air outlet pipes are arranged in a ring at equal intervals on the inner wall of the annulus.

[0012] Furthermore, the flow guide is a stainless steel flow guide.

[0013] Furthermore, threaded holes are provided on both sides of the angle adjustment device, and angle adjustment bolts are connected to the threads in the threaded holes. The inner side of the angle adjustment bolts abuts against the outer periphery of the first air outlet pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the dust removal fan delivers air to the annular ring through the outlet duct. The airflow enters the first outlet duct through the corrugated pipe, and a spiral airflow is formed by the spiral protrusions of the spiral component and the support column. The airflow is blown out from the outward-facing guide component. The angle adjustment device can adjust the blowing angle to clean the lens at the center of the annular ring. Multiple annular equidistant first outlet ducts and the angle adjustment device reduce dead angles. The spiral airflow enhances the peeling force, the corrugated pipe improves flexibility, the outward-facing guide component expands the range and distributes the force evenly, the stainless steel material extends the service life, the clean airflow avoids damage to the lens, and the dust sensor is kept clean to ensure measurement accuracy.

[0015] 2. In this utility model, the outward-flaring guide at the end of the first air outlet can expand the range of airflow, allowing the airflow to cover the lens surface more evenly and improve the cleaning effect on the lens. At the same time, the outward-flaring design can reduce the resistance when the airflow is blown out, so that the airflow maintains a certain intensity and prevents dust from remaining at the edge. In addition, the outward-flaring guide can reduce the force of the airflow directly impacting the lens and reduce the potential impact on the lens. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 This utility model provides a technical solution: See Figures 1-5 As shown, a self-cleaning device for a total station reflector used for building deformation monitoring includes a detector body 1. A circular ring 2 is fixedly installed on the detector body 1. The interior of the circular ring 2 is hollow, and an angle adjustment device 3 is provided on the inner wall of the circular ring 2. A corrugated pipe is provided on the angle adjustment device 3, and a first air outlet pipe 4 is installed at the other end of the corrugated pipe. Threaded holes are opened on both sides of the angle adjustment device 3, and angle adjustment bolts are threaded into the threaded holes. The inner side of the angle adjustment bolts abuts against the outer circumference of the first air outlet pipe 4. When it is necessary to adjust the outlet angle of the first air outlet pipe 4, the angle adjustment bolts are loosened. A groove is opened on the outer circumference of the first air outlet pipe 4 at the position corresponding to the angle adjustment bolt.

[0020] The first air outlet duct 4 has a spiral component 6 inside, a support column 7 on the spiral component 6, and a spiral protrusion 8 inside the support column 7. A dust removal fan 10 is installed on one side of the detector body 1, and the air inlet of the dust removal fan 10 is connected to the first ventilation duct 4.

[0021] The inner ring 2 on the main body 1 of the detector is hollow. The dust removal fan 10 delivers airflow into the ring 2 through the air supply pipe 11. The airflow is distributed through the ring 2 to the corrugated pipe connected by multiple angle adjustment devices 3, and then enters the first air outlet pipe 4. The spiral part 6 inside the first air outlet pipe 4 cooperates with the spiral protrusion 8 inside the support column 7 to form a spiral airflow during the flow process. Finally, it is blown out from the outward-turned guide part 5 at the end of the first air outlet pipe 4. At the same time, the angle adjustment device 3 can adjust the blowing angle of the first air outlet pipe 4 to clean the lens 13 located at the center of the ring 2.

[0022] Multiple first air outlet ducts 4 arranged in a ring at equal intervals and angle adjustment devices 3 can blow the lens 13 from different angles, reducing cleaning dead angles; the spiral component 6 and spiral protrusions 8 make the airflow spiral, enhancing the airflow's peeling force on the dust surface of the lens 13 and improving the cleaning effect; the corrugated pipe can flexibly change the position of the first air outlet duct 4 in conjunction with the angle adjustment device 3 to adapt to different cleaning needs; the outward-turned guide component 5 can expand the airflow blowing range, making the surface of the lens 13 more evenly stressed; the stainless steel guide component 5 is wear-resistant and easy to clean, which can extend the service life of the device; the overall structure cleans through airflow, avoiding contact with the lens 13 and preventing damage, while quickly responding to the detection results of the dust sensor 12, keeping the lens 13 clean in time, and ensuring the measurement accuracy of the total station.

[0023] See Figure 1 Multiple fixing rods 9 are fixedly installed between the first air outlet pipe 4 and the spiral component 6. The fixing rods 9 are cylindrical.

[0024] Multiple cylindrical fixing rods 9 between the first air outlet duct 4 and the spiral component 6 can firmly connect the two, preventing the spiral component 6 from shaking or shifting under the impact of airflow, ensuring the stable formation of spiral airflow. At the same time, the cylindrical design can reduce the obstruction to airflow, allowing airflow to pass more smoothly through the spiral component 6 and the support column 7. Multiple fixing rods 9 distribute the force, enhance the overall structural strength, and extend the service life of the device.

[0025] See Figure 1 The end of the first air outlet duct 4 away from the angle adjustment device 3 is provided with an outward-curving guide 5.

[0026] The outward-flaring guide 5 at the end of the first air outlet duct 4 can expand the range of airflow, allowing the airflow to cover the surface of the lens 13 more evenly, thus improving the cleaning effect on the lens 13. At the same time, the outward-flaring design can reduce the resistance when the airflow is blown out, so that the airflow maintains a certain intensity and prevents dust from remaining at the edges. In addition, the outward-flaring guide 5 can reduce the force of the airflow directly impacting the lens 13, reducing the potential impact on the lens 13.

[0027] See Figure 1A dust removal fan 10 is provided on one side of the detector body 1. An air supply pipe 11 is fixedly installed at the bottom of the dust removal fan 10, and the other end of the air supply pipe 11 is fixedly installed on the ring 2.

[0028] The dust removal fan 10 on one side of the detector body 1 is connected to the ring 2 through the air supply pipe 11, which can provide a stable airflow source for the device, ensuring that the airflow continuously enters the ring 2 and is distributed to each first air outlet pipe 4 to meet the air force required for cleaning. The fixed installation of the air supply pipe 11 can ensure the airtightness during the airflow transmission process, reduce air force loss, and enable the airflow to reach the cleaning area efficiently, ensuring the automatic cleaning effect on the lens 13.

[0029] See Figures 1-2 A dust sensor 12 is installed on the inner wall of the ring 2. The dust sensor 12 is connected to an external controller; the dust removal fan 10 is also connected to the controller.

[0030] The dust sensor 12 on the inner wall of the ring 2 can monitor the dust around the lens 13 in real time. When the dust accumulates to a certain level, it can trigger the dust removal fan 10 to start the cleaning process in time, so as to avoid the dust affecting the measurement accuracy of the total station. It eliminates the need for frequent manual inspections, reduces manual intervention, and makes cleaning more timely and intelligent.

[0031] See Figures 1-2 The detector body 1 is equipped with a lens 13, which is located at the center of the ring 2.

[0032] The lens 13 on the detector body 1 is positioned at the center of the ring 2, allowing multiple first air outlets 4 on the inner wall of the ring 2 to deliver airflow to the lens 13 from different angles, ensuring that the airflow evenly covers the surface of the lens 13 and reducing cleaning dead zones. At the same time, the center position is compatible with the measurement optical path of the total station, ensuring that the lens 13 can accurately receive and reflect the laser signal of the total station, ensuring the normal operation of the measurement work, and also allowing the dust sensor 12 to more accurately monitor the dust around the lens 13 and trigger cleaning actions in a timely manner.

[0033] See Figures 1-2 Multiple angle adjustment devices 3 and first air outlet pipes 4 are configured, and the angle adjustment devices 3 and first air outlet pipes 4 are arranged in a ring with equal spacing on the inner wall of the ring 2.

[0034] Multiple angle adjustment devices 3 and first air outlet pipes 4 are arranged in an evenly spaced ring on the inner wall of the ring 2, allowing multiple airflows to simultaneously sweep the lens 13 from different directions, covering all areas of the lens 13 surface, reducing cleaning dead corners, and improving the overall cleaning effect. At the same time, the evenly spaced distribution makes the airflow force on the lens 13 surface more uniform, avoiding excessively strong or weak local airflow from affecting the cleaning quality. They can also work with the angle adjustment devices 3 to adjust the sweeping angle, flexibly responding to the dust accumulation in different positions of the lens 13, further ensuring the cleanliness of the lens 13 to meet measurement requirements.

[0035] See Figure 4 The flow guide 5 is a stainless steel flow guide.

[0036] The air guide 5 is made of stainless steel, which can resist corrosion caused by moisture, dust and other factors in the outdoor monitoring environment, thus extending the service life of the air guide 5. At the same time, the surface of stainless steel is smooth and has high hardness, making it less likely to attract dust or be scratched or deformed by daily airflow impact. This reduces the frequency of cleaning the air guide 5 itself and also ensures the stability of the airflow when it is blown out of the air guide 5, avoiding the impact of damage to the air guide 5 on the cleaning effect of the lens 13.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
