DETAILED DESCRIPTION

[0034] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

In this paper, "one" not only means "only one", but also means "more than one".

[0037] In this paper, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] In addition, in the description of the present application, the terms "first", "second", etc. are only used for differentiation and cannot be understood as indicating or implying relative importance.

[0040] In the fields of engineering construction, industrial manufacturing, geographic mapping and intelligent building, accurate height measurement and positioning operation is a key link in many project implementations. The traditional laser leveling instrument and detector cooperative working mode has significant limitations, which mainly relies on manual control of the detection rod or detection scale for lifting operation to realize accurate laser irradiation of the target position and obtain the corresponding height data, and then relies on manual calculation to obtain the height difference.

[0041] However, in practical application scenarios such as construction of large building communities, installation and debugging of complex industrial production lines, topographic mapping of vast areas, and internal facility layout of modern intelligent buildings, when multiple measurement targets are involved or frequent height measurement operations need to be performed at different positions, the traditional method exposes many thorny problems. The operator must constantly manually adjust the height of the scale, which undoubtedly greatly increases the work burden and labor intensity; at the same time, since the manual reading of height and the subsequent calculation of height difference are tedious and easily affected by subjective factors, the probability of calculation error and data recording error is significantly increased; in addition, such frequent manual operation makes the entire measurement workflow lack of continuity and efficiency, seriously restricting the overall progress speed and work efficiency of the project, and it is difficult to meet the urgent needs of today's industries for high-precision and high-efficiency measurement operations.

[0042] To solve the problems existing in the prior art, with reference to the drawings attached to the specification Figure 1 The detection device provided by the present application can quickly and accurately obtain the height of the target position, reduce the error of manual reading and calculation, improve the measurement accuracy and efficiency, and ensure the accuracy and reliability of the data.

[0043] In one embodiment, with reference to the drawings attached to the specification Figure 1 and Figure 2The detection device provided by the application comprises a base 1, an identification section 2, a power module 3, a detection module 4 and an indicator.

[0044] The base 1 serves as the basic support of the entire device and provides a stable mounting platform for other components. The identification section 2 is connected to the base 1 through the power module 3, and the operation of the power module 3 can cause the identification section 2 to displace relative to the base 1. The detection module 4 is arranged on the identification section and can displace with it. Meanwhile, the indicator in the detection device can display the height of the plane where the laser of the laser leveling instrument is located on the detection device.

[0045] The conventional measurement method needs to manually adjust the height of the device repeatedly when facing multiple target positions, which is tedious and time-consuming. The detection device provided by the application uses the power module 3 to drive the identification section 2 to displace automatically, which greatly reduces the measurement time. For example, when measuring the elevation of multiple positions on different floors in a construction site, the operator only needs to input parameters, and the power module 3 can quickly drive the identification section 2 to the position, greatly improving the measurement efficiency and saving the labor cost.

[0046] It should be noted that, in general, the base 1 can be made of metal or high-strength engineering plastic with sufficient strength and stability. Its shape and structure design should ensure that it can provide a stable support foundation for the entire detection device in various measurement environments, including but not limited to common geometric shapes such as rectangles, circles or triangles. In addition, its surface can be specially treated to enhance wear resistance and corrosion resistance.

[0047] In this embodiment, the indicator is a key component that directly presents the measurement result. Based on the displacement of the identification section, it indicates the height of the plane where the laser of the laser leveling instrument is located. Its setting form is diverse to meet the needs of different users and usage scenarios.

[0048] The indicator can usually be selected from physical indicating devices (pointers) or electronic indicating devices, etc., for intuitive display of the height of the target position. Its display accuracy can be adjusted according to actual measurement requirements, including but not limited to accuracy to millimeters, centimeters or higher, so that the operator can quickly and accurately read the measurement data and reduce errors caused by reading. For example, the electronic indicating device can have a microprocessor and a display screen built-in, and is electrically connected to the detection module 4 and the power module 3. The laser position signal transmitted by the detection module 4 is analyzed and processed by the microprocessor in real time, converted into corresponding height values, and then presented in digital form on the display screen.

[0049] It should be noted that based on the above, it can be understood that the surface or predetermined part of the identification section 2 has corresponding marks, which can be in the form of scales (scale marks), such as high-precision printed millimeter and centimeter scales, which accurately present length information; or in the form of codes, which correspond to specific height values through different colors, shapes, and numerical combinations, facilitating subsequent identification and data processing.

[0050] In general, the indicator, especially the pointer form, is provided on the base 1. Specifically, when the indicator is in the form of a pointer, the identification section 2 is provided with scale marks, for example, linear scales can be used to uniformly distribute measurement values; for some high-precision measurement scenarios, non-linear scales can also be used to make more precise scale divisions in key measurement areas to improve measurement accuracy. In actual operation, as the power module 3 drives the identification section 2 to displace relative to the base 1, the pointer will point to the corresponding scale mark on the identification section 2, thereby obtaining the height of the laser plane.

[0051] Optionally, the surface of the identification section 2 can be specially treated, such as coated with a wear-resistant and corrosion-resistant coating, to prolong its service life.

[0052] Further, the detection device further includes a control end, which is connected to the detection module 4 and the power module 3. The connection can be electrical connection through wires or wireless communication technology.

[0053] Specifically, when the laser emitted by the laser leveling instrument irradiates the target position, the detection module 4 provided on the identification section 2 will detect the position of the laser and transmit the detection signal to the control end. The control end analyzes and processes the received signal through internal algorithms and sends a control signal to the power module 3, thereby accurately controlling the displacement of the identification section 2.

[0054] Based on the above embodiment, further, the base 1 is hollow inside and has a mounting space 100 along its height direction to accommodate at least part of the power module 3.

[0055] It can be understood that this design makes the overall structure of the detection device more compact and regular. By reasonably utilizing the space inside the base 1 to accommodate the power module 3, the additional space occupied by the power module 3 outside is avoided, the overall external profile of the device is reduced, and it is easier to arrange and operate in some limited space working environment.

[0056] On the other hand, the installation space 100 inside the base 1 provides a relatively stable and protected operating environment for the power module 3. When the power module 3 operates within this space, its power transmission path is more direct and stable, reducing power loss or transmission failures that may be caused by external factors (such as collisions, dust, humidity, etc.). Moreover, since the base 1 typically has good stability and vibration resistance, the fact that the power module 3 is partially housed in the base 1 also reduces the impact of external vibrations or interference on the operation of the power module 3 to some extent.

[0057] Optionally, a fixed bracket or guide rail can be installed within the installation space 100 to securely install and position the power module 3, ensuring that it will not shift or shake during operation, thereby further improving the stability and reliability of the system.

[0058] like Figure 3 As shown, in one embodiment, a support part 31 is provided at the bottom of the power module 3 as a bottom support structure for the power module 3. The bottom surface of the support part 31 is flush with the bottom surface of the installation space 100. Thus, when the power module 3 is installed in the installation space 100, the bottom surface of the support part 31 abuts against the bottom surface of the installation space 100, providing a stable support foundation for the power module 3 and effectively preventing it from shaking and displacing during operation.

[0059] Understandably, when the power module 3 is activated and drives the marker segment 2 to perform lifting and lowering actions, various forces are generated, including the power generated by the operation of the power module 3, the inertial force caused by the high-speed movement of the marker segment 2, and the resistance generated by internal friction of the system. The stable contact formed between the support part 31 and the bottom surface of the installation space 100 efficiently and evenly transmits these forces to the base 1, effectively avoiding the risk of deformation, twisting, or even damage to structural components caused by localized force concentration.

[0060] In one embodiment, the power module 3 includes a fixed end 32 and an output end 33. The fixed end 32 is fixed in the installation space 100, while the output end 33 is movably engaged with the fixed end 32 and connected to the marking segment 2. Meanwhile, an opening is provided on one side of the installation space 100 to allow part of the power module 3 to extend to the outside.

[0061] In this embodiment, the connection method between the output terminal 33 and the identifier segment 2 is not limited, and there can be two forms: direct connection and indirect connection.

[0062] When a direct connection is adopted, the output end 33 is closely connected with the identification section 2, for example, when the power module 3 is a cylinder, it can be directly connected to the moving end of the cylinder. This connection method is simple and direct, the power transmission path is short, the movement of the output end 33 of the power module 3 can be quickly and accurately transmitted to the identification section 2, reducing the energy loss and potential error sources of the intermediate links, so that the identification section 2 can quickly respond to the driving of the power module 3, and efficient displacement adjustment is realized.

[0063] Indirect connection is to realize the connection between the output end 33 and the identification section 2 through intermediate transmission components. The selection of intermediate transmission components depends on the specific application scene and performance requirements, for example, connecting rod mechanism, gear transmission pair, flexible transmission belt, etc. can be used.

[0064] At the same time, in the setting of indirect connection, due to the replaceability and adjustability of the intermediate transmission components, when some components are worn or performance is reduced, only the corresponding intermediate transmission components need to be replaced or repaired, without the need to replace the whole power module 3 and identification section 2, effectively controlling the maintenance cost, prolonging the service life of the equipment, and ensuring the reliability and stability of the detection equipment in the long-term use process.

[0065] Optionally, based on the content of the present embodiment, the output end 33 can be a slider structure, the slider moves up and down along the linear guide rail arranged on the fixed end 32, ensuring high precision and low friction of movement. At the same time, a connection part is arranged on the slider for connection with the identification section 2, so as to realize the displacement of the identification section 2.

[0066] In addition, in some embodiments, the identification section 2 can be received into the installation space 100 through the opening of the installation space 100, so as to be effectively protected, avoiding the influence of external collision, dust, moisture and other adverse factors in the equipment transportation, storage or non-working state, prolonging the service life of the identification section 2 and ensuring the stability of its performance.

[0067] In one embodiment, specifically, the power module 3 includes a driving motor 35 and a transmission mechanism 34. The driving motor 35 is installed into the installation space 100 of the base 1, and the motor stator is fixed to the inner wall of the installation space 100, constituting the fixed end 32 described above, providing stable support and positioning for the whole power module 3, ensuring that displacement or shaking will not occur during operation. The output shaft of the driving motor 35 serves as the output end 33 of the power module 3, which is connected with the identification section 2 through the transmission mechanism 34, so as to convert the rotary motion of the driving motor 35 into the linear motion of the identification section 2.

[0068] It should be noted that the design of the transmission mechanism 34 in this embodiment has multiple forms, and can be selected and optimized according to different measurement requirements and accuracy requirements to realize the function of intermediate transmission. For example, a gear and rack transmission mechanism 34 can be selected, a small gear is installed on the output shaft of the driving motor 35, and is engaged with a gear rack fixed on the identification section 2. When the motor rotates, the small gear drives the gear rack to move linearly, thereby pushing the identification section 2 to ascend or descend.

[0069] Based on the above embodiment, in one embodiment, as shown in Figure 4 The transmission mechanism 34 includes a screw rod 341 and a threaded sleeve 342 that are connected in series. The output shaft of the driving motor 35 is connected to the threaded sleeve 342, which ensures that power can be stably transmitted to the threaded sleeve 342 when the motor is running, so that it rotates with it. The internal threads of the threaded sleeve 342 and the external threads of the screw rod 341 are accurately matched to form a stable transmission connection. The other end of the screw rod 341 is connected to the identification section 2. This connection can be achieved by welding, high-strength bolt connection or a specially designed connecting joint to ensure that the connection between the two is firm and can accurately transmit motion.

[0070] It should be noted that a limiting structure is provided between the identification section 2 and the base 1. Through the setting of the limiting structure, the rotation of the driving motor 35 can be accurately and accurately converted into the linear motion of the screw rod 341 and the threaded sleeve 342, so that the identification section 2 can freely and smoothly slide in the vertical direction, while effectively limiting its rotational freedom. Alternatively, corresponding guide rails and guide grooves can be provided on the identification section 2 and the base 1 respectively to avoid transmission failure due to synchronous rotation of the two.

[0071] In this embodiment, when the driving motor 35 receives a running instruction from the control end and starts to work, its output shaft drives the threaded sleeve 342 to rotate. Due to the action of the threads, the screw rod 341 is forced to move linearly along its axial direction under the rotational motion of the threaded sleeve 342. The linear motion of the screw rod 341 is directly transmitted to the identification section 2 connected thereto, so that the identification section 2 can stably ascend or descend in the vertical direction, thereby accurately adjusting the height position of the detection module 4 to adapt to the height measurement requirements of different target positions.

[0072] Conversely, in some cases, the screw rod 341 is connected to the output shaft of the driving motor 35, and the threaded sleeve 342 is relatively fixed with the identification section 2. At this time, the motor rotates to drive the screw rod 341 to rotate. Since the screw rod 341 is fixed, the threaded sleeve 342 will move linearly along its own axis relative to the screw rod 341 during rotation, thereby driving the identification section 2 to move.

[0073] In the embodiment, the transmission mode of the screw rod 341 and the threaded sleeve 342 has high transmission accuracy, and can accurately convert the rotation of the output shaft of the driving motor 35 into the micro linear displacement of the identification section 2. The linear movement distance of the screw rod 341 corresponding to each rotation is fixed and can be accurately calculated, which enables accurate control of the lifting of the identification section 2 and meets the application scenarios with high requirements on measurement accuracy.

[0074] In one embodiment, the detection module 4 is arranged outside the identification section 2, that is, directly exposed to the environment during detection, and can unhinderedly receive the laser signal from the laser leveling instrument. This arrangement enables the optical receiving component of the detection module 4 to adopt a relatively conventional design, for example, using a large-area photosensitive element or an optical lens group to enhance the receiving ability and sensitivity of the laser signal.

[0075] Specifically, the laser beam emitted by the laser leveling instrument forms a horizontal reference plane in space, and when the detection module 4 is in a suitable position, the laser beam directly irradiates the receiving area of the detection module 4, the photosensitive element converts the light signal into an electrical signal, and then transmits the signal to the subsequent signal processing circuit and control unit. Since the detection module 4 is directly in contact with the external environment, its signal receiving process is relatively simple and direct, reducing the signal attenuation and interference that may be caused by the light transmission medium.

[0076] In contrast to the previous embodiment, in one embodiment, the detection module 4 is arranged inside the identification section 2, and a receiving window is arranged on the identification section 2, the position of the receiving window corresponds to the optical receiving component of the detection module 4, and ensures that the laser can smoothly pass through the receiving window to reach the detection module 4.

[0077] The material of the receiving window is usually selected from transparent materials with good optical transmittance and wear resistance and corrosion resistance, such as high-strength acrylic plates or quartz glass, to ensure that the laser signal can enter the inside of the identification section 2 with minimal attenuation. The detection module 4 is relatively protected inside the identification section 2, reducing the direct impact and pollution of the external environment.

[0078] In summary, the arrangement of the detection module 4 outside or inside the identification section 2 has its own advantages and application scenarios. In actual application, the appropriate implementation mode can be selected according to the specific measurement environment, accuracy requirements, and cost budget, etc., to ensure that the detection device can accurately and reliably perform height measurement work under various complex working conditions.

[0079] In one embodiment, the identification section 2 is a telescopic rod, as shown in Figure 5 The telescopic rod includes at least two rod bodies 21, each rod body 21 is designed as a hollow structure, and adjacent two rod bodies 21 are connected by sliding.

[0080] It can be understood that the hollow design not only reduces the overall weight, but also facilitates the movement of the power module 3, and provides a certain installation and arrangement space for the internal connecting parts or lines.

[0081] The first rod body 21 is connected with the output end 33 of the power module 3, as a direct receiving component of power, driving the entire telescopic rod to perform telescopic movement. The last rod body 21 is connected with the base 1, and the connection mode can adopt fixed pins, bolt connections or card slot cooperation, etc., to ensure the firm fixation of the telescopic rod on the base 1, and also provides a stable support basis for the telescopic movement of the telescopic rod, preventing displacement or shaking during measurement due to stress, thereby ensuring the accuracy of the measurement data.

[0082] When the telescopic rod is in the stretched state, the horizontal position of the first rod body 21 is higher than that of any other rod body 21. This design ensures that during the measurement process, when the power module 3 drives the telescopic rod to stretch or contract, each rod body 21 can rise or fall in a predetermined order, avoiding the phenomenon of jamming or interference, and ensuring the stability and reliability of the measurement action.

[0083] Under the action of the power module 3, the working process of the telescopic rod is as follows: when it is necessary to raise the identification section 2 for measurement, the power module 3 drives the first rod body 21 to rise, and due to the sliding connection between adjacent rod bodies 21, the first rod body 21 will push the second rod body 21 to rise during the rising process, the second rod body 21 will drive the third rod body 21 to rise, and so on, each rod body 21 rises in turn, realizing the stretching of the telescopic rod, so as to reach the required measurement height; when the measurement is completed and the identification section 2 needs to be lowered, the power module 3 drives the first rod body 21 to descend, and under the action of gravity and friction between the rod bodies 21, each rod body 21 descends in turn, realizing the contraction of the telescopic rod, and returning to the initial state or other specified storage position.

[0084] Under the setting of the present embodiment, the design of the telescopic rod enables the identification section 2 to realize accurate height adjustment within a larger range, meets the measurement needs of different height targets, reduces the situation that cannot be measured due to length limitation, and improves the versatility and practicality of the detection equipment. When the detection equipment is in a non-working state or needs to be transported and stored, the telescopic rod can be contracted to the shortest state, greatly reducing the overall occupied space, facilitating carrying and storage.

[0085] It should be noted that in the form of telescopic rod, there are various forms for reading the physical scale. One of them, for each rod body 21 that constitutes the telescopic rod, a scale can be set respectively (on the outer surface of each rod body 21, scale marks are marked along the length direction); when the telescopic rod is stretched, the operator can read the scale values exposed on each rod body 21 respectively, and then add these values to obtain the total measured height. Another one, the entire telescopic rod can be regarded as a whole, and a continuous scale is set, when the telescopic rod is stretched, no matter how the internal rod body 21 is stretched, only the scale value at the corresponding position of the rod body 21 closest to the base 1 side needs to be read to obtain the measured height.

[0086] In addition, in addition to the traditional scale reading mode, a digital display device can also be provided on the detection device, the stretching length of the telescopic rod is monitored through a sensor (such as a displacement sensor), and a signal is transmitted to the control unit, and the control unit displays the measured height in digital form on the display screen after calculation. Optionally, the digital display device can also have a data storage function, which can record the height data of multiple measurement points, facilitating subsequent data query, analysis and processing.

[0087] In one embodiment, the detection device is also provided with a power supply module 5. One setting form is that the power supply module 5 of the detection device uses a power supply unit, which simultaneously supplies power to the power module 3, the detection module 4 and the control end. In this setting form, only one power source is needed, the overall structure of the device is more compact, the number of parts is reduced, and the manufacturing cost is reduced. For example, a rechargeable lithium battery pack is used, and the power is evenly distributed to each module that needs power supply through a pre-designed circuit wiring.

[0088] Correspondingly, the power supply module 5 includes a plurality of independent power supply units, specifically, the first power supply unit supplies power to the power module 3 alone, the second power supply unit supplies power to the detection module 4 alone, and the third power supply unit supplies power to the control end alone. This form can improve the power supply stability and reliability of each module and reduce electrical interference between modules.

[0089] For example, for the power module 3, the first power supply unit generally selects a power module that can provide high current output to ensure that the driving motor 35 can operate stably, avoid unstable power output caused by voltage fluctuation, and thus ensure accurate lifting control of the identification section 2. For another example, the third power supply unit of the control end generally uses a power module with good voltage stabilization performance and anti-interference ability to ensure that the electronic components of the control end can work stably, prevent faults such as program error, data loss or communication interruption caused by power supply problems, and ensure the normal operation of the entire detection device and the accuracy of data processing.

[0090] In one embodiment, the detection device further comprises a communication module, which includes a Bluetooth communication module, a wireless communication module, and a wired communication module. One or more of them can be selected according to actual conditions, or a combination of them can be selected to adapt to various complex use environments and application requirements.

[0091] In the detection device, the Bluetooth communication module allows the detection device to quickly establish a wireless connection with nearby user devices (such as smartphones, tablets, etc.). For example, in the measurement operation of a small indoor space, such as a home decoration scene, the construction personnel only need to turn on the Bluetooth function on the mobile phone and pair with the detection device, and then use the specially developed APP to easily operate the detection device to measure, and record the measurement data on the mobile phone in real time.

[0092] Further, the wireless communication module (such as common Wi-Fi, 4G, 5G, etc. Technology) provides the detection device with a wider communication range and higher data transmission rate, so that it can break through the short distance limitation of Bluetooth, realize stable connection and data interaction with remote user devices. For example, in complex environments such as large commercial buildings and industrial plants, the detection device can be connected to the existing Wi-Fi network, and the operator can control and monitor the detection device from any location in the building, and at the same time manage multiple detection devices distributed in different areas, obtain a large amount of measurement data in real time, and upload these data to the cloud server for storage, analysis and sharing.

[0093] Although wireless communication technology has advantages in terms of convenience, in some specific scenarios, a wired communication module can still be selected. For example, in environments with extremely high requirements for data transmission stability, real-time performance, and security, wired communication methods can ensure that data transmission is not disturbed by external wireless signals, and ensure data integrity and accuracy.

[0094] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred embodiment of the present application, and it should be noted that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
