Description

Technical Field

[0001] This invention relates to the field of building surveying technology, and more specifically to a building surveying device for civil engineering construction. Background Technology

[0002] In civil engineering construction, building surveying equipment is a key tool to ensure the accurate implementation of projects. Total stations integrate optics, mechanics, and electronics, and can simultaneously measure angles and distances, quickly obtaining three-dimensional coordinates. They are widely used in topographic surveying, construction layout, and other applications, greatly improving surveying efficiency and accuracy. Laser rangefinders utilize the high directionality of lasers to quickly and accurately measure distances. They are easy to operate and suitable for scenarios such as interior decoration and small building surveying. Levels are used to determine the height difference between two points on the ground. With the cooperation of a leveling rod and a telescope, they provide reliable data for elevation measurement, ensuring the verticality and horizontality of buildings. GPS receivers, with the help of satellite positioning systems, achieve large-scale, high-precision positioning measurements, playing an important role in large-scale engineering site planning and topographic mapping. In addition, there are theodolites for measuring horizontal and vertical angles, and traditional surveying tools such as steel tapes serve as auxiliary tools, collectively constructing a comprehensive equipment system for civil engineering surveying, contributing to the high-quality advancement of projects.

[0003] Chinese patent publication number CN119803406A discloses a construction surveying device, including a connecting column. One end of the connecting column is connected to a first moving mechanism, and the first moving mechanism is connected to a second moving mechanism. The lower end of the second moving mechanism is connected to a laser level. By setting the first moving mechanism, the fixed plate is tilted, allowing rainwater to flow on the fixed plate to the inlet. The inlet collects and stores the rainwater, which is then sprayed out through the connecting column to clean the laser level. By setting two worm gears, the movement path of the laser level on the second moving mechanism can be controlled by controlling the rotation speed and direction of the worm gears. This allows the entire device to be installed in an absolutely safe position, and the laser level can be moved to the measurement position. This not only makes the use of the laser level safer but also increases the measurement range of the device.

[0004] Currently, when using laser ranging in civil engineering construction surveying equipment, a blower is used to adsorb dust around the laser path and filter it with a filter plate. However, as the adsorption capacity of the filter plate decreases, the filter surface cannot be replaced in time, resulting in the surrounding dust concentration not being effectively reduced after filtration. This affects the laser propagation path and the final measurement results. In addition, a single laser cannot effectively detect the lateral flatness of the wall surface. This often requires additional devices or methods to check the flatness of the wall surface after the wall construction is completed, increasing the complexity and time cost of the measurement work. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a building surveying device for civil engineering construction to solve the problems existing in the background art.

[0006] This invention provides the following technical solution: a building surveying device for civil engineering construction, comprising a support base, the support base including a support plate, a traveling wheel rotatably connected to the bottom of the support plate, a rotating plate fixedly connected to the top of the support plate, a housing of a first motor fixedly connected to the center of the rotating plate, an outer shell fixedly connected to the shaft of the first motor, a laser emitter fixedly connected to one end of the outer shell, a fan assembly installed behind the laser emitter, a filter plate assembly installed behind the fan assembly, a moving assembly installed above the filter plate assembly, flow meters installed on the front and rear sides of the filter plate assembly, the flow meters being located inside the outer shell, a stirring assembly installed below the outer shell, and a cleaning assembly installed inside the outer shell;

The rotating connecting plate is rotatably connected to the rotating plate and is fixedly connected to the shaft of the first motor. The stirring assembly is located inside the cleaning chamber, and the size of the through square holes is smaller than the minimum telescopic tube size of the telescopic protective shell.

[0009] Furthermore, the moving component includes a second motor, a first screw fixedly connected to the shaft of the second motor, a drive wheel fixedly connected to the upper end of the first screw, a belt movably connected to the outer side of the drive wheel, a driven wheel movably connected to the other end of the belt, one end of a second screw fixedly connected to the center of the driven wheel, the lower ends of the first and second screws rotatably connected to a ventilation pipe, a first bracket rotatably connected to the upper ends of the first and second screws, the lower end of the first bracket fixedly connected to the ventilation pipe, and the second and first screws respectively helically connected to a transmission block.

[0011] Furthermore, the stirring assembly includes a fourth motor, the housing of which is fixedly connected to a rotating connecting plate, and a stirring fan is fixedly connected to the shaft of the fourth motor, the stirring fan being located inside the cleaning chamber.

[0012] Furthermore, the stirring fan includes an assembly ring, with a plurality of fan blades arranged in a circular array on the outer side of the assembly ring, and a vortex groove provided on one side of the fan blades.

[0016] This invention, through the setting of structures such as a moving component and a filter plate assembly, activates the moving component when the flow meter detects a decrease in the filtration performance of the filter plate. Through a series of transmissions, the filter plate is lowered, and the telescopic protective shell retracts, thereby replacing the filter surface of the filter plate. This ensures that the equipment effectively filters dust in front of the laser emitter, reduces dust concentration, avoids affecting the laser propagation path, and thus ensures the accuracy of the final measurement results.

[0017] This invention features a first motor that, when the horizontal flatness of a wall needs to be measured, is activated to rotate a laser emitter to the left or right, using a laser point to measure the flatness of the wall. This eliminates the need for additional devices or methods, reducing the complexity and time cost of the measurement work. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The civil engineering construction surveying equipment involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figures 1-3This invention provides a building surveying device for civil engineering construction, including a support base 1, a support plate 101, a walking wheel 102 rotatably connected to the bottom of the support plate 101, a rotating plate 103 fixedly connected to the top of the support plate 101, a housing of a first motor 104 fixedly connected to the center of the rotating plate 103, a housing 2 fixedly connected to the shaft of the first motor 104, a laser emitter 3 fixedly connected to one end of the housing 2, a fan assembly 6 installed behind the laser emitter 3, a filter plate assembly 5 installed behind the fan assembly 6, a moving assembly 4 installed above the filter plate assembly 5, flow meters 7 installed on the front and rear sides of the filter plate assembly 5, the flow meters 7 being located inside the housing 2, a stirring assembly 8 installed below the housing 2, and a cleaning assembly 9 installed inside the housing 2.

[0028] The filter plate assembly 5 includes a telescopic protective shell 501. The filter plate component 503 is fixedly connected inside the uppermost telescopic shell of the telescopic protective shell 501. The transmission blocks 502 are fixedly connected to the outer sides of the uppermost telescopic shell of the telescopic protective shell 501. The transmission blocks 502 are connected to the moving component 4 by a screw drive.

[0029] In this embodiment, it should be specifically noted that the laser emitter 3 is connected to an external power source, which provides power to the laser emitter 3 when necessary.

[0030] Reference Figures 1-3 The outer casing 2 includes a ventilation pipe 201. The upper and lower walls of the ventilation pipe 201 have through square holes 202. A cleaning chamber 203 is fixedly connected to the bottom of the through square holes 202. The cleaning chamber 203 communicates with the ventilation pipe 201 through the through square holes 202. A rotating connecting plate 204 is fixedly connected to the bottom of the cleaning chamber 203. The bottom of the ventilation pipe 201 is supported by a support column 205. The other end of the support column 205 is fixedly connected to the top of the rotating connecting plate 204. The rotating connecting plate 204 is rotatably connected to the rotating plate 103. The rotating connecting plate 204 is fixedly connected to the rotating shaft of the first motor 104. The stirring assembly 8 is located inside the cleaning chamber 203.

[0031] In this embodiment, it should be specifically noted that the size of the through square hole 202 is smaller than the minimum telescopic tube size of the telescopic protective shell 501.

[0032] Reference Figures 1-4The moving component 4 includes a second motor 401. The shaft of the second motor 401 is fixedly connected to a first screw 403. The upper end of the first screw 403 is fixedly connected to a drive wheel 402. The outer side of the drive wheel 402 is movably connected to a belt 405. The other end of the belt 405 is movably connected to a driven wheel 404. The center of the driven wheel 404 is fixedly connected to one end of a second screw 406. The lower ends of the first screw 403 and the second screw 406 are rotatably connected to the ventilation pipe 201. The upper ends of the first screw 403 and the second screw 406 are rotatably connected to a first bracket 407. The lower end of the first bracket 407 is fixedly connected to the ventilation pipe 201. The second screw 406 and the first screw 403 are respectively screw-driven connected to the transmission block 502.

[0033] In this embodiment, it should be specifically explained that during the test, if the flow meter 7 detects that the flow rate has decreased to a certain level, it indicates that the filtration performance of the filter plate has greatly decreased and the filter surface needs to be replaced. At this time, the second motor 401 is started, which drives the first screw 403 to rotate. The first screw 403 drives the drive wheel 402 to rotate, and the drive wheel 402 drives the driven wheel 404 and the second screw 406 to rotate through the belt 405. The simultaneous rotation of the first screw 403 and the second screw 406 drives the transmission block 502 to descend, and the filter plate 503 also descends accordingly. The telescopic protective shell 501 begins to retract under the obstruction of the ventilation pipe 201. When the filter plate 503 descends to the set distance, the filter surface changes, but the effective operation of the equipment can still be guaranteed.

[0034] Reference Figure 2 and Figure 3 The fan assembly 6 includes a third motor 601, which is located at the air inlet end of the ventilation duct 201. A second bracket 602 is fixedly connected to the outer side of the housing of the third motor 601. The second bracket 602 is fixedly connected to the inner wall of the ventilation duct 201. A fan component 603 is fixedly connected to the shaft of the third motor 601.

[0035] In this embodiment, it should be specifically explained that: the third motor 601 is started, and the third motor 601 drives the fan 603 to rotate, which adsorbs the dust in front of the laser emitter 3, thereby reducing the dust concentration in front of the laser emitter 3. The dust passes through the filter plate 503 behind the fan 603. After being filtered by the filter plate 503, the airflow flows out from the rear of the ventilation pipe 201. The flow meters 7 in front of and behind the filter plate 503 always monitor the flow rate in front of and behind the filter plate 503.

[0036] Reference Figure 3 The stirring assembly 8 includes a fourth motor 801. The housing of the fourth motor 801 is fixedly connected to the rotating connecting plate 204. The rotating shaft of the fourth motor 801 is fixedly connected to a stirring fan 802, which is located inside the cleaning chamber 203.

[0037] In this embodiment, it should be specifically noted that: the stirring fan 802 is on the movement path of the filter plate 503, but the height of the cleaning chamber 203 ensures that the stirring fan 802 does not come into contact with the filter plate 503.

[0038] Reference Figure 3 and Figure 6 The stirring fan 802 includes an assembly ring 8021, a plurality of fan blades 8022 arranged in a circular array on the outer side of the assembly ring 8021, and a vortex groove 8023 provided on one side of the fan blades 8022.

[0039] In this embodiment, it should be specifically explained that when the fourth motor 801 is started, the fourth motor 801 drives the stirring fan 802 to rotate. Due to the presence of the vortex groove 8023, the stirring fan 802 generates vortices during rotation, which makes the surface of the filter plate 503 cleaner under the rinsing of the moving water.

[0040] Reference Figure 3 and Figure 5 The cleaning assembly 9 includes a fifth motor 901, the shaft of which is fixedly connected to a third screw 902. The outer side of the third screw 902 is helically connected to a brush assembly 903. The brush assembly 903 is slidably connected to a guide rod 904. The housing of the fifth motor 901 is fixedly connected to the bottom inner wall of the ventilation pipe 201. The third screw 902 and the guide rod 904 are rotatably connected to the cleaning chamber 203.

[0041] In this embodiment, it should be specifically explained that after the measurement is completed, when a large part of the filter plate 503 falls into the cleaning chamber 203, a sufficient amount of cleaning solution is injected into the cleaning chamber 203, the fifth motor 901 is started, the fifth motor 901 drives the third screw 902 to rotate, and the third screw 902 drives the brush assembly 903 to move back and forth downwards or downwards to perform friction cleaning on the filter plate 503.

[0042] Reference Figure 3 and Figure 7 The brush assembly 903 includes a brush block 9031. The brush block 9031 has through holes 9032 and threaded holes 9035 at both ends. The through holes 9032 are slidably connected to the guide rod 904, and the threaded holes 9035 are helically connected to the third screw 902. The side of the brush block 9031 is fixedly connected with several arrays of mounting grooves 9033, and several bristles 9034 are arrayed inside the mounting grooves 9033.

[0043] In this embodiment, it should be specifically noted that the length of the brush bristles 9034 is easily rubbed against the filter plate 503 during the movement, causing friction cleaning of the filter plate 503.

[0044] The specific steps are as follows:

[0045] First, when distance measurement is required in civil engineering construction, this equipment is moved to a specific measurement position via the walking wheels 102. Then, the walking wheels 102 are fixed so that the ventilation pipe 201 is parallel to the support plate 101. The third motor 601 is started, and the third motor 601 drives the fan component 603 to rotate, adsorbing the dust in front of the laser emitter 3, thereby reducing the dust concentration in front of the laser emitter 3. The dust passes through the filter plate 503 behind the fan component 603. After being filtered by the filter plate 503, the airflow flows out from the rear of the ventilation pipe 201. The flow meters 7 in front of and behind the filter plate 503 always monitor the flow rate in front of and behind the filter plate 503.

[0046] Start the laser emitter 3. The laser emitted by the laser emitter 3 is emitted onto the wall. The distance to be measured is determined by calculating the time. At this time, if it is necessary to measure the horizontal flatness of the wall, start the first motor 104. The first motor 104 drives the rotating connecting plate 204 and the laser emitter 3 to rotate to the left or right, and the flatness of the wall is measured.

[0047] During the test, if the flow meter 7 detects that the flow rate has dropped to a certain level, it indicates that the filtration performance of the filter plate has greatly decreased and the filter plate surface needs to be replaced. At this time, the second motor 401 is started. The second motor 401 drives the first screw 403 to rotate, and the first screw 403 drives the drive wheel 402 to rotate. The drive wheel 402 drives the driven wheel 404 and the second screw 406 to rotate through the belt 405. The simultaneous rotation of the first screw 403 and the second screw 406 drives the transmission block 502 to descend, and the filter plate 503 also descends accordingly. The telescopic protective shell 501 begins to retract under the obstruction of the ventilation pipe 201. When the filter plate 503 descends to the set distance, the filter surface changes, but the equipment can still operate effectively.

[0048] After the measurement is completed, when a large portion of the filter plate 503 falls into the cleaning chamber 203, a sufficient amount of cleaning solution is injected into the cleaning chamber 203. The fifth motor 901 is then started, which drives the third screw 902 to rotate. The third screw 902 drives the brush assembly 903 to move back and forth downwards or downwards. At this time, the bristles 9034 rub against the filter surface of the filter plate 503, thus cleaning the surface of the filter plate 503. Simultaneously, the fourth motor 801 is started, which drives the stirring fan 802 to rotate. Due to the presence of the vortex groove 8023, the stirring fan 802 generates vortices during rotation, making the surface of the filter plate 503 even cleaner under the rinsing of the moving water.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
