Description

Technical Field

[0001] The invention relates to the technical field of metallurgy or coking engineering, and in particular to a distance-finder reflector cleaning device. Background Art

[0002] The description in this section merely provides background information related to the present disclosure and may not constitute prior art.

[0003] In recent years, gas holders have been widely used and well received in metallurgical enterprises and coking enterprises because of their excellent functions of stabilizing pipeline pressure, recovering and storing gas, reducing gas emission and improving gas utilization rate.

[0004] Usually, a rangefinder reflector is often installed on the upper part of the gas tank piston. This reflector is a supporting auxiliary device for reflecting laser, radar, ultrasonic and other types of cabinet level meters. However, due to the poor environment inside the cabinet, the reflector is installed on the upper part of the piston inside the gas tank, and the surface is prone to dirt and grime. Especially on the thin oil seal type gas tank, the reflector may also be splashed with oil spots of sealing oil, causing the laser, radar, ultrasonic and other reflected waves of the cabinet level meter hitting the reflector to be weakened or unable to reflect normally, resulting in increased measurement errors of the cabinet level meter, failure or signal flickering, and inability to correctly reflect the actual cabinet capacity, thereby causing omissions in the gas tank operation monitoring. In addition, the high and low cabinet capacities of the gas tank need to be safety interlocked. Failure to correctly monitor the cabinet capacity will increase the safety risks of the gas tank.

[0005] To address the above-mentioned issues, an existing automatic cleaning device for a laser reflector includes a reflector, support platforms are provided at both ends of the reflector, limit baffles are provided on both sides of the support platforms, a drive motor is provided on the outer side of the limit baffle, a transmission shaft is provided in the middle of the inner side of the limit baffle, a guide rail is provided at the inner bottom of the limit baffle, a moving block is provided at the top of the guide rail, a connecting rod is provided on one side of the moving block, and a hanging brush is provided at the bottom of the connecting rod. This device can, to a certain extent, remotely and regularly clean the oil stains on the reflector, avoiding the accumulation of oil stains that affects the reflector's reflection of the laser beam, resulting in inaccurate and fluctuating detection data. It also avoids employees from frequently entering the gas cabinet to clean the reflector, reducing their labor intensity. However, the reflector surface is usually covered with a reflective film. When the brush mechanically moves through the connecting rod to clean the reflector surface, if it encounters stubborn dirt or hard particles, it is easy to damage the reflective film. In addition, when the brush cleans the oil spots on the reflector, it will contaminate the brush. Reusing it may cause secondary contamination of the reflector.

[0006] It should be noted that the above technical background is merely provided to provide a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. Simply because these solutions are described in the technical background section of the present invention, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0061] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0062] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an element centered thereon. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an element centered thereon.

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0064] like Figure 1 and Figure 2 As shown, the present invention provides a rangefinder reflector cleaning device, wherein the rangefinder reflector 100 has a reflecting surface 110 facing the rangefinder and a back surface 120 facing away from the rangefinder, and the rangefinder reflector cleaning device includes:

[0065] The support mechanism 200 includes a base structure 210 and a lifting structure 220. The base structure 210 is mounted on the top surface A of the gas tank piston. The rangefinder reflector 100 has a top end 130 and a bottom end 140 that are opposite each other. The bottom end 140 of the rangefinder reflector 100 is rotatably connected to the base structure 210. The lifting structure 220 is telescopically connected between the top end 130 and the top surface A of the rangefinder reflector 100 to drive the rangefinder reflector 100 to swing about the bottom end 140 and change the angle between the rangefinder reflector 100 and the top surface A.

[0066] The vibration mechanism 300 is provided on the back surface 120 of the rangefinder reflector 100 , and the vibration mechanism 300 can drive the rangefinder reflector 100 to vibrate;

[0067] The blowing mechanism 400 is disposed at the top end 130 of the rangefinder reflector 100 . The blowing mechanism 400 can blow airflow toward the reflecting surface 110 of the rangefinder reflector 100 .

[0068] The rangefinder reflector cleaning device provided by the present invention can place the rangefinder reflector 100 on the top surface A of the gas tank piston through the support mechanism 200, and drive the rangefinder reflector 100 to swing through the lifting structure 220 to adjust the angle between the rangefinder reflector 100 and the top surface A, that is, to adjust the angle between the rangefinder reflector 100 and the vertical direction, so that impurities on the reflective surface 110 of the rangefinder reflector 100 can fall along the reflective surface 110 of the rangefinder reflector 100 under the influence of gravity; at the same time, the vibration mechanism 300 is installed on the The back side 120 of the rangefinder reflector 100 can, through the synergistic effect of vibration and the gravity exerted on the dirt, vibrate the impurities or dirt on the reflecting surface 110 of the rangefinder reflector 100 and make it roll down along the inclination of the rangefinder reflector 100; furthermore, the blowing mechanism 400 installed at the top 130 of the rangefinder reflector 100 can blow airflow toward the reflecting surface 110, so that the impurities or dirt vibrated off the reflecting surface 110 can follow the airflow and along the surface space of the reflecting surface 110 to leave the rangefinder reflector 100, thereby achieving more efficient cleaning.

[0069] The rangefinder reflector cleaning device provided by the present invention uses gas, vibration, and adjustment of the angle between the reflective surface 110 and the top surface A to blow away dirt and attachments on the rangefinder reflector 100, which is not easy to damage the reflective film on the reflective surface 110 and avoids secondary contamination of the reflective film.

[0070] The rangefinder reflector cleaning device provided by the present invention can be fully automated in an electronically controlled manner, avoiding the operator from repeatedly and frequently entering the cabinet for cleaning, reducing the workload of inspection personnel, and lowering safety risks and operation and maintenance costs.

[0071] For reference Figure 1 As shown, specifically in this embodiment, the base structure 210 is mounted on the top surface A of the gas tank piston, and the two opposite ends of the rangefinder reflector 100 are respectively a top end 130 and a bottom end 140, wherein the top end 130 is a free end and the bottom end 140 is a rotating end. In this embodiment, the rangefinder reflector 100 is a rectangular plate. In other embodiments, the specific shape of the rangefinder reflector 100 is not limited; in this embodiment, refer to Figure 3 As shown, a hinge device 500 is provided between the bottom end 140 of the rangefinder reflector 100 and the base structure 210. The bottom end 140 of the rangefinder reflector 100 is rotatably connected to the base structure 210 via the hinge device 500. The hinge device 500 has two rotating parts 510. The angle between the two rotating parts 510 can be set variable. One of the two rotating parts 510 is connected to the bottom end 140 of the rangefinder reflector 100, and the other is connected to the base structure 210.

[0072] In this embodiment, the lifting structure 220 is retractable, that is, when the lifting structure 220 contracts, the angle between the rangefinder reflector 100 and the top surface A is reduced, and when the lifting structure 220 extends, the angle between the rangefinder reflector 100 and the top surface A is increased; in this embodiment, the position where the lifting structure 220 is connected to the rangefinder reflector 100 is set close to the top 130 of the rangefinder reflector 100, which is convenient for lifting or resetting the rangefinder reflector 100.

[0073] In this embodiment, the vibration mechanism 300 is generally a vibration motor. In other embodiments, the vibration mechanism 300 may also use other vibration elements 310. In this embodiment, the vibration motor is placed on the back side 120 of the rangefinder reflector 100 to avoid being installed on the reflective surface 110 of the rangefinder reflector 100, which would cause obstruction and damage to the reflective surface 110.

[0074] In this embodiment, the blowing mechanism 400 is arranged at the top end 130 of the rangefinder reflector 100, and blows air toward the reflecting surface 110. When the rangefinder reflector 100 swings around its bottom end 140 to a state where the rangefinder reflector 100 forms a certain angle with the top surface A, the flow direction of the airflow blown by the blowing mechanism 400 is from the high point of the rangefinder reflector 100 to the low point of the rangefinder reflector 100, which can be combined with the direction in which impurities or dirt roll under the influence of gravity, so as to facilitate the rapid blowing of impurities separated by vibration away from the rangefinder reflector 100, thereby avoiding secondary contamination of the rangefinder reflector 100 by impurities.

[0075] like Figure 2 As shown, in one embodiment,

[0076] The base structure 210 includes two parallel support rods 211 fixed to the top surface A. The rangefinder reflector 100 is located between the two support rods 211, and the two sides of the bottom end 140 of the rangefinder reflector 100 are rotatably connected to the two support rods 211 respectively.

[0077] In this embodiment, the two support rods 211 are respectively connected to the two sides of the bottom end 140 of the rangefinder reflector 100, which can improve the installation stability of the rangefinder reflector 100 on the top surface A and avoid overturning when the rangefinder reflector 100 is lifted or vibrated.

[0078] Specifically in this embodiment, the support rod 211 is generally a rectangular cube-shaped rod. The support rod 211 extends in a direction parallel to the top surface A. One side of the support rod 211 is connected to the top surface A, and the other opposite side of the support rod 211 is connected to the rangefinder reflector 100. In this embodiment, the two support rods 211 are arranged in parallel to provide uniform supporting force. The two sides of the bottom end 140 of the rangefinder reflector 100 in this embodiment are respectively connected to the two support rods 211 through the hinge device 500.

[0079] In a specific embodiment, both sides of the bottom end 140 of the rangefinder reflector 100 are rotatably connected to one end of the two support rods 211, which simplifies the specific structure of the base structure 210. When the rangefinder reflector 100 swings, the gravity of the support rod 211 and the thrust of the lifting structure 220 on the rangefinder reflector 100 can achieve torque balance relative to one end of the support rod 211, making the process of adjusting the angle between the rangefinder reflector 100 and the top surface A more stable, avoiding the support rod 211 and the top surface A being affected by the force of different torques, resulting in a stable decrease in the connection between the support rod 211 and the top surface A.

[0080] like Figure 2 As shown, in one embodiment,

[0081] Two opposite side edges 150 are formed between the top end 130 and the bottom end 140 of the rangefinder reflector 100 . The two side edges 150 are arranged parallel to each other and are arranged in the same vertical plane as the axes of the two support rods 211 .

[0082] In the rangefinder reflector cleaning device provided in this embodiment, the side edges 150 of the rangefinder reflector 100 between the top end 130 and the bottom end 140 are set to two, and the two side edges 150 are opposite and parallel to each other. This can avoid the presence of more than two side edges 150 between the top end 130 and the bottom end 140, which would cause the rangefinder reflector 100 to have an irregular shape. In other words, when the rangefinder reflector 100 is swinging, the torque applied to each side edge is different, which would cause the rangefinder reflector 100 to be easily deformed or have poor swing stability during the swinging process.

[0083] Specifically in this embodiment, the rangefinder reflector 100 has a rectangular parallelepiped structure, and the two side edges 150 are respectively arranged in the same vertical plane as the axes of the two support rods 211, that is, one end of the side edge 150 is rotatably connected to the support rod 211, and one end of the side edge 150 is also on one side of the bottom end 140, so that during the swinging process of the rangefinder reflector 100, the side edge 150 is always located in the same vertical plane as the axis of the support rod 211, and no force perpendicular to the axis of the support rod 211 is generated along the top surface A. In other words, interference between the rotational connection of the rangefinder reflector 100 and the support rod 211 is avoided, which is conducive to the normal swinging of the rangefinder reflector 100 and also helps to increase the service life of the base structure 210.

[0084] like Figure 2 As shown, in one embodiment,

[0085] The lifting structure 220 has a fixed end 221 and a retractable movable end 222. One of the fixed end 221 and the movable end 222 is hinged to the top surface A, and the other is connected to the back surface 120. The movable end 222 can push the rangefinder reflector 100 to swing around its own bottom end 140.

[0086] In this embodiment, the lifting structure 220 has a movable end 222 and a fixed end 221 respectively provided on the top surface A and the back surface 120, which can drive the rangefinder reflector 100 to swing around its own bottom end 140 by pushing the back surface 120 of the rangefinder reflector 100.

[0087] Specifically in this embodiment, the lifting structure 220 is generally a hydraulic push rod. In other embodiments, the lifting structure 220 can also be an electrically driven rod. In this embodiment, when there is dirt on the reflective surface 110 of the rangefinder reflector 100, the movable end 222 of the lifting structure 220 extends relative to the fixed end 221, pushing the rangefinder reflector 100 to swing around its own bottom end 140 until it stops at a certain angle to the top surface A, so that the dirt can slide down along the reflective surface 110 of the rangefinder reflector 100 under the influence of gravity.

[0088] like Figures 2 to 6 As shown, in one embodiment,

[0089] The rangefinder reflector 100 can swing around the bottom end 140 between a first position and a second position;

[0090] When the rangefinder reflector 100 swings to the first position, the angle between the rangefinder reflector 100 and the top surface A is 0°; when the rangefinder reflector 100 swings to the second position, the angle between the rangefinder reflector 100 and the top surface A is 60°.

[0091] In this embodiment, the angle between the rangefinder reflector 100 and the top surface A can be switched between 0° and 60°. Within this angle range, the rangefinder reflector 100 can balance the gravity of the dirt itself, the influence of the jet airflow, and the vibration effect of the vibration mechanism 300 to achieve the optimal dirt removal effect; that is, it can avoid the situation where the dirt re-contaminates the reflecting surface 110 along the airflow due to the angle between the rangefinder reflector 100 and the top surface A being too large.

[0092] Specifically in this embodiment, when the rangefinder reflector 100 swings to the first position, the angle between the rangefinder reflector 100 and the top surface A is 0°, that is, the back surface 120 of the rangefinder reflector 100 is in contact with the side surface of the support rod 211 .

[0093] like Figure 2 As shown, in one embodiment,

[0094] There are multiple lifting structures 220 , which respectively form a first lifting group and a second lifting group that are arranged in parallel and symmetrically. The first lifting group and the second lifting group are respectively arranged close to the two side edges 150 of the rangefinder reflector 100 .

[0095] The rangefinder reflector cleaning device provided in this embodiment can evenly lift the rangefinder reflector 100 through the symmetrically arranged first lifting group and the second lifting group, thereby avoiding the situation where, due to the asymmetrical arrangement of multiple lifting structures 220, the multiple lifting structures 220 lift the rangefinder reflector 100, resulting in uneven vibration intensity at different parts of the rangefinder reflector 100 during the vibration process, thereby affecting the vibration effect of the rangefinder reflector 100.

[0096] Specifically in this embodiment, the multiple lifting structures 220 are equally divided into a first lifting group and a second lifting group. The multiple lifting structures 220 of the first lifting group are arranged at intervals along a direction parallel to the side 150 of the rangefinder reflector 100. In a specific embodiment, the multiple lifting structures 220 of the first lifting group are arranged at intervals along a direction parallel to the axial direction of the support rod 211. The multiple lifting structures 220 of the second lifting group in this embodiment are arranged at intervals along a direction parallel to the other opposite side 150 of the rangefinder reflector 100. In a specific embodiment, the multiple lifting structures 220 of the second lifting group are arranged at intervals along a direction parallel to the axial direction of the other opposite support rod 211.

[0097] In this embodiment, the symmetrically arranged first lifting group and the second lifting group, that is, the multiple lifting structures 220 arranged at intervals in the first lifting group and the multiple lifting structures 220 arranged at intervals in the second lifting group are symmetrical relative to the center line of the rectangular rangefinder reflector 100.

[0098] like Figure 2 As shown, in one embodiment,

[0099] The distance from one end of the lifting structure 220 connected to the rangefinder reflector 100 to the top 130 of the rangefinder reflector 100 forms a first distance, and the distance from the bottom 140 to the top 130 of the rangefinder reflector 100 forms a second distance, wherein the ratio of the first distance to the second distance is 0.2 to 0.4.

[0100] The rangefinder reflector cleaning device provided in this embodiment limits the position where the lifting structure 220 is connected to the rangefinder reflector 100, so that the lifting structure 220 set at this position of the rangefinder reflector 100 can conveniently push the rangefinder reflector 100 to swing, and can also facilitate the lifting structure 220 to accurately control the swing angle of the rangefinder reflector 100.

[0101] Specifically in this embodiment, the ratio of the first distance to the second distance is 0.2 to 0.4, that is, the rangefinder reflector 100 is divided into five equal sections along the direction from the bottom end 140 to the top end 130 of the rangefinder reflector 100, wherein the position where the lifting structure 220 is connected to the rangefinder reflector 100 is located in the second area in the direction from the top end 130 to the bottom end 140 of the rangefinder reflector 100. In a specific embodiment, the positions where the multiple lifting structures 220 are connected to the rangefinder reflector 100 are all located in the second area in the direction from the top end 130 to the bottom end 140 of the rangefinder reflector 100. In this embodiment, the positions where the multiple lifting structures 220 are connected to the rangefinder reflector 100 are symmetrically arranged. In other embodiments, the positions where the multiple lifting structures 220 are connected to the rangefinder reflector 100 can also be asymmetrically arranged.

[0102] like Figure 2 As shown, in one embodiment,

[0103] The vibration mechanism 300 includes a plurality of vibration elements 310 , which are divided into a first vibration group and a second vibration group that are symmetrically arranged. The first vibration group and the second vibration group are respectively arranged near the two side edges 150 of the rangefinder reflector 100 .

[0104] The rangefinder reflector cleaning device provided in this embodiment can uniformly vibrate the rangefinder reflector 100 through the symmetrically arranged first vibration group and the second vibration group, thereby avoiding the problem that the rangefinder reflector 100 cannot provide uniform vibration force at all parts of the reflective surface during the common vibration of the multiple vibration elements 310 due to the asymmetrical arrangement of the multiple vibration elements 310, thereby avoiding the problem of affecting the dust removal effect of the rangefinder reflector 100.

[0105] Specifically, in this embodiment, the plurality of vibration elements 310 are equally divided into a first vibration group and a second vibration group. The number of vibration elements 310 in the first vibration group is the same as the number of vibration elements 310 in the second vibration group. The plurality of vibration elements 310 in the first vibration group are spaced apart in a direction parallel to the side 150 of the rangefinder reflector 100. In this embodiment, the plurality of vibration elements 310 in the second vibration group are spaced apart in a direction parallel to the other opposite side 150 of the rangefinder reflector 100. That is, the straight line formed by the plurality of vibration elements 310 in the first vibration group is parallel to the straight line formed by the plurality of vibration elements 310 in the second vibration group.

[0106] In this embodiment, the symmetrically arranged first vibration group and the second vibration group, that is, the multiple vibration elements 310 of the first vibration group arranged at intervals and the multiple vibration elements 310 of the second vibration group arranged at intervals are symmetrical relative to the center line of the rectangular rangefinder reflector 100.

[0107] like Figure 2 As shown, in one embodiment,

[0108] The distance from the vibration element 310 to the top 130 of the rangefinder reflector 100 forms a third distance, and the distance from the bottom 140 to the top 130 of the rangefinder reflector 100 forms a second distance, wherein a ratio of the third distance to the second distance is 0.4-0.6.

[0109] The rangefinder reflector cleaning device provided in this embodiment can facilitate the installation of the vibration element 310 by limiting the position where the vibration element 310 connects to the rangefinder reflector 100, while also improving the vibration dust removal effect of the vibration element 310 on the rangefinder reflector 100.

[0110] Specifically, in this embodiment, the ratio of the third distance to the second distance is 0.4 to 0.6, that is, the rangefinder reflector 100 is divided into five equal sections along the direction from the bottom end 140 to the top end 130 of the rangefinder reflector 100. The position where the vibration element 310 is installed on the rangefinder reflector 100 is within the third section in the direction from the top end 130 to the bottom end 140 of the rangefinder reflector 100. In a specific embodiment, the positions at which the multiple vibration elements 310 are installed on the rangefinder reflector 100 are all within the third section in the direction from the top end 130 to the bottom end 140 of the rangefinder reflector 100. In this embodiment, the positions at which the multiple vibration elements 310 are installed on the rangefinder reflector 100 are symmetrically arranged. In other embodiments, the positions at which the multiple vibration elements 310 are installed on the rangefinder reflector 100 can also be asymmetrical.

[0111] like Figure 2 、 Figures 4 to 6 As shown, in one embodiment,

[0112] The top 130 of the rangefinder reflector 100 is formed with a top edge 131 parallel to the top surface A. The blowing mechanism 400 includes a blowing pipe 410, which extends along the top edge 131. The blowing pipe 410 is provided with a plurality of blowing ports 420 spaced apart. The blowing ports 420 are arranged toward the reflecting surface 110 for blowing airflow toward the reflecting surface 110.

[0113] The rangefinder reflector cleaning device provided in this embodiment can stably and evenly blow airflow to the reflective surface 110 by setting multiple blowing ports 420, and can blow the dirt separated by the vibration element 310 on the reflective surface 110 away from the rangefinder reflector 100, avoiding the occurrence of a blowing dead angle caused by the opening of a single blowing port 420.

[0114] Specifically in this embodiment, the rangefinder reflector 100 is a rectangular structure, the top edge 131 of the rangefinder reflector 100 is perpendicular to the two side edges 150 of the rangefinder reflector 100, and the blow pipe 410 is extended along the top edge 131, that is, the opening direction of the multiple blow ports 420 is located within the range defined by the two side edges 150 of the rangefinder reflector 100, and the blow ports 420 are arranged toward the reflecting surface 110, that is, the airflow blown out of the blow ports 420 can also blow dirt from the reflecting surface 110.

[0115] like Figure 2 、 Figures 4 to 6 As shown, in one embodiment,

[0116] A first angle B is formed between the direction of the blowing port 420 and the reflecting surface 110 , and the first angle B is 0° to 1°.

[0117] The rangefinder reflector cleaning device provided in this embodiment is adjusted to a setting between 0° and 1° by limiting the first angle B between the direction of the nozzle 420 and the reflective surface 110. The direction of the nozzle 420 within this angle range can balance the influence of the interaction between the nozzle airflow and the vibration effect of the vibration mechanism 300, thereby achieving the optimal decontamination effect; that is, it can avoid the situation where the airflow damages the reflective film or the dirt returns to and contaminates the reflective surface 110 due to the first angle B between the direction of the nozzle 420 and the reflective surface 110 being too large.

[0118] like Figure 2 As shown, in one embodiment,

[0119] The blowing mechanism 400 further includes an air compression tank 430 and an air hose 440 , and the blowing pipe 410 is connected to the air compression tank 430 via the air hose 440 .

[0120] The rangefinder reflector cleaning device provided in this embodiment directs the high-pressure air output by the air compression tank 430 into the blowing pipe 410 through the air hose 440. The pressure in the compressed air tank in this embodiment cannot be adjusted, but a higher-pressure compressed air tank can be selected according to the blowing effect, or a compressed air tank with adjustable output pressure can be provided.

[0121] In other embodiments, the gas ejected from the compressed air tank can also be replaced with nitrogen to avoid problems such as corrosion of the reflective surface 110, or the use of cleaning gases such as high-temperature steam can further enhance the decontamination effect of the spraying mechanism 400.

[0122] In one embodiment,

[0123] The support rod 211 is made of a non-metallic material with vibration absorbing properties.

[0124] The rangefinder reflector cleaning device provided in this embodiment can alleviate the risk of generating unstable factors or noise when the vibration mechanism 300 vibrates the rangefinder reflector 100, by replacing the material of the support rod 211 with a non-metallic material with vibration-absorbing properties. In other words, the vibration mechanism 300 can achieve the effect of only vibrating the rangefinder reflector 100.

[0125] Specifically, in this embodiment, the support rod 211 is made of wood. In other embodiments, other vibration-absorbing non-metallic materials may also be used. There is no specific limitation on the specific material of the support rod 211.

[0126] like Figure 2 As shown, in a specific embodiment, the working principle of the rangefinder reflector cleaning device is as follows:

[0127] When dirt accumulates on the reflective surface 110, the movable end 222 of the lifting structure 220 extends and pushes the rangefinder reflector 100 to swing around the bottom end 140 until the angle between the rangefinder reflector 100 and the top surface A reaches a desired fixed angle, and then stops.

[0128] Furthermore, the valve of the compressed air tank 430 is opened, and high-pressure air enters the blowing pipe 410 through the air hose 440, and is then sprayed from the plurality of blowing ports 420 spaced apart on the blowing pipe 410 onto the reflecting surface 110, thereby clearing away dirt on the reflecting surface 110;

[0129] Furthermore, while the valve of the compressed air tank 430 is opened, the plurality of vibrating elements 310 of the vibrating mechanism 300 on the back surface 120 are energized and vibrated. In this way, dirt and dust adhering to the rangefinder reflector 100 are blown off by the dual action of vibrating the rangefinder reflector 100 and blowing air, thereby achieving the purpose of cleaning the reflective surface 110 of the rangefinder reflector 100.

[0130] After the cleaning work is completed, the multiple vibration elements 310 of the vibration mechanism 300 are powered off and stop vibrating, the valve of the air compression tank 430 is closed, the movable end 222 of the lifting structure 220 retracts and drives the rangefinder reflector 100 to swing around the bottom end 140 in the direction where the angle between the rangefinder reflector 100 and the top surface A is 0° to reset, that is, the side of the rangefinder reflector 100 is connected to the support rod 211.

[0131] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
