Description

Technical Field

[0001] This utility model relates to the technical field of solar thermal power generation equipment, specifically to an automatic detection and adjustment device for a trough concentrator column. Background Technology

[0002] Solar thermal power generation is an important aspect of solar energy utilization. Currently, there are four main types: trough, tower, Fresnel, and disc. The basic process involves using a solar concentrator to track the sun and concentrate solar radiation onto a heat-absorbing device, thereby obtaining high-temperature thermal energy. This thermal energy is then used for conventional power generation or other medium-to-high-temperature applications. The solar concentrator is a key component of solar thermal power generation and medium-to-high-temperature solar energy utilization systems, especially the trough solar concentrator. During its promotion and application, it has been found that the installation of its support columns significantly restricts the development of trough concentrators.

[0003] Existing technology for adjusting the column of a trough-type concentrator mainly uses a total station, a reflecting prism, and special tooling. This method is not intuitive, and the adjustment amount cannot be fed back in real time. It requires repeated measurement and adjustment by adjustment personnel and surveyors, is easily affected by the external environment, and the measurement accuracy varies greatly depending on the surveyor, making re-measurement difficult. Utility Model Content

[0004] The purpose of this invention is to provide an automatic detection and adjustment device for trough-type concentrator columns, so as to solve the problems of low efficiency caused by the need for adjustment and measurement personnel to repeatedly measure and adjust during the installation and adjustment process of trough-type concentrator columns in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic detection and adjustment device for a trough-type concentrator column includes:

[0007] The transmitting end is detachably mounted on the bearing seat of the end column and is used to emit laser signals in the direction of the column to be adjusted and to receive laser signals reflected by the receiving end; the laser axis emitted by the transmitting end is collinear with the axis of the bearing seat of the end column.

[0008] The receiving end is detachably mounted on the bearing seat of the column to be adjusted, and is used to receive the laser signal sent by the transmitting end and reflect the laser signal to the transmitting end; the center of the receiving end coincides with the midpoint of the axis of the bearing seat of the column to be adjusted.

[0009] A movable robotic arm is positioned close to the column to be adjusted to adjust its position and angle.

[0010] The control terminal is connected to the transmitter and receiver to generate adjustment information and control the movable robotic arm to adjust the column to a preset position and angle. This setup allows the control terminal to directly control the movable robotic arm to adjust the position of the column, eliminating the need for manual operation and preventing inaccurate measurements due to human error. It also eliminates the need for repeated measurements and adjustments by personnel, effectively improving column installation efficiency.

[0011] Furthermore, the transmitting end includes a laser measuring instrument, which is used to measure the distance between the laser measuring instrument and the receiving end, as well as the deviation between the laser signal and the center point of the receiving end; the laser measuring instrument has a cylindrical surface for mating with the inner surface of the bearing housing. The mating of the cylindrical surface of the laser measuring instrument and the inner surface of the bearing housing ensures that the laser emitted by the laser measuring instrument and the axis of the bearing housing are coaxial; by setting this cylindrical surface, it is convenient to quickly determine the installation position of the laser measuring instrument and to disassemble it easily.

[0012] Furthermore, the receiving end includes a reflector and a photoelectric sensor. The back of the reflector has a cylindrical surface for mating with the inner surface of the bearing housing, and the photoelectric sensor is located at the center point of the front of the reflector. The cylindrical surface of the reflector mates with the inner surface of the bearing housing, ensuring that the center of the reflector coincides with the midpoint of the axis of the bearing housing of the column to be adjusted. The cylindrical surface facilitates quick determination of the reflector's installation position and allows for easy disassembly, enabling rapid installation onto the next column to be adjusted, thus improving column installation efficiency.

[0013] Furthermore, the control terminal includes a computer, and both the transmitting end and the movable robotic arm are connected to the computer via signal. The computer has a pre-set algorithm. Operators can control the transmitting end to emit laser signals to the receiving end via the computer. Subsequently, the transmitting end and the receiving end feed back laser signal information to the computer. The pre-set algorithm calculates the distance and angle deviation between the column to be adjusted and the end column based on the laser signal received by the receiving end and the laser signal reflected from the receiving end to the transmitting end. Based on the preset position and angle values, it calculates the adjustment information for the column to be adjusted. Based on the adjustment information, it controls the movable robotic arm to adjust the column to the preset position and angle. The adjustment amount can also be displayed in real time on the computer, allowing operators to promptly understand the adjustment progress.

[0014] Furthermore, the movable robotic arm includes a control system and an adjustment system for the movable column to be adjusted; the control system is connected to a control terminal signal; and controls the adjustment system to adjust the column to be adjusted to a preset position and angle according to the adjustment information issued by the control terminal.

[0015] Furthermore, the movable robotic arm also includes a drive system for moving the movable robotic arm.

[0016] Furthermore, the mobile robotic arm also includes an energy storage system for providing power to the control system, adjustment system, and drive system.

[0017] Furthermore, a bearing seat is installed at the top of the end column, and the bottom of the end column has two support legs, both of which are connected to the ground via fixed feet. By providing two support legs, the support and balance of the column can be improved.

[0018] Furthermore, the fixing foot has a fixing groove, the center of which is used to connect with the support leg, and bolt holes symmetrically distributed along the support leg are formed in the fixing groove. The symmetrical bolt holes improve the stability of the column after installation.

[0019] Furthermore, the column to be adjusted and the end column have the same structure and dimensions. There is no need to distinguish the column structure during installation, effectively improving installation efficiency.

[0020] This invention has the following advantages over the prior art:

[0021] This utility model discloses an automatic detection and adjustment device for a slotted concentrator column, which is equipped with a transmitter, a receiver, a movable robotic arm, and a control terminal. The transmitter is installed on the bearing seat of the end column, and the receiver is installed on the bearing seat of the column to be adjusted. The control terminal is connected to the transmitter and receiver for signal transmission. Adjustment information is generated based on the laser signal emitted by the transmitter and the laser signal reflected by the receiver, thereby controlling the robotic arm to adjust the column to a preset position and angle. The entire adjustment process is completed automatically, and the adjustment amount is visible in real time through the control terminal. Manual adjustment by personnel is not required, avoiding inaccurate measurement results caused by human factors. Attached Figure Description

[0029] Example:

[0030] like Figure 1 As shown, this utility model provides an automatic detection and adjustment device for a slotted concentrator column, comprising: a transmitter 1, a receiver 3, a movable robotic arm 5, and a control end 6; the transmitter 1 is detachably mounted on the bearing seat 7 of the end column 2, and is used to emit laser signals toward the column 4 to be adjusted and to receive laser signals reflected by the receiver 3; the laser axis emitted by the transmitter 1 is collinear with the axis of the bearing seat 7 of the end column 2; the receiver 3 is detachably mounted on the bearing seat 7 of the column 4 to be adjusted, and is used to receive the laser signals from the transmitter 1 and reflect the laser signals back to the transmitter 1; the center of the receiver 3 coincides with the midpoint of the axis of the bearing seat 7 of the column 4 to be adjusted; the movable robotic arm 5 is positioned close to the column 4 to be adjusted, and is used to adjust the position and angle of the column 4 to be adjusted; the control end 6 is signal-connected to the transmitter and receiver to generate adjustment information, and controls the movable robotic arm 5 to adjust the column 4 to a preset position and angle according to the adjustment information.

[0031] In this embodiment, the control terminal 6 can control the transmitter 1 to emit a laser signal, and obtain adjustment information based on the laser signal received by the receiver 3 and the laser signal reflected from the receiver 3 to the transmitter 1. Based on the adjustment information, the control terminal 6 can directly control the movable robotic arm 5 to adjust the position of the column 4 to be adjusted, without the need for manual operation by staff, thus avoiding the problem of inaccurate measurement results caused by human factors. It also eliminates the need for adjustment and measurement personnel to repeatedly measure and adjust, effectively improving the efficiency of column installation.

[0032] Specifically, in this embodiment, the transmitting end 1 includes a laser measuring instrument, which is used to measure the distance between the laser measuring instrument and the receiving end 3, as well as the deviation between the laser signal and the center point of the receiving end 3. In actual use, the laser measuring instrument can be a combination of an existing laser rangefinder and a collimator. The laser measuring instrument has a cylindrical surface for mating with the inner surface of the bearing seat 7. The mating of the cylindrical surface of the laser measuring instrument and the inner surface of the bearing seat 7 ensures that the laser emitted by the laser measuring instrument is coaxial with the axis of the bearing seat. By setting this cylindrical surface, it is easy to quickly determine the installation position of the laser measuring instrument and to disassemble it easily.

[0033] The receiving end 3 includes a reflector and a photoelectric sensor. The back of the reflector has a cylindrical surface for mating with the inner surface of the bearing seat, and the photoelectric sensor is located at the center point of the front of the reflector. The mating of the cylindrical surface of the reflector and the inner surface of the bearing seat ensures that the center of the reflector coincides with the midpoint of the axis of the bearing seat of the column 4 to be adjusted. The cylindrical surface facilitates the quick determination of the reflector's installation position and allows for easy disassembly, enabling rapid installation onto the next column to be adjusted, thus improving column installation efficiency.

[0034] In this implementation, the control terminal 6 includes a computer, and the transmitter 1, receiver 3, and movable robotic arm 5 are all connected to the computer via signal. Specifically, the laser measuring instrument at the transmitter can be directly connected to the computer via a data cable. The computer has a preset algorithm, allowing the operator to control the transmitter 1 to emit laser signals to the receiver 3. Subsequently, the transmitter 1 and receiver 3 send laser signal information back to the computer. The preset algorithm in the computer calculates the distance and angle deviation between the column to be adjusted 4 and the end column 2 based on the laser signal received by the receiver 3 and the laser signal reflected from the receiver 3 to the transmitter 1. Based on the preset position and preset angle values, the adjustment information for the column to be adjusted 4 is calculated. The movable robotic arm is then controlled to adjust the column to the preset position and angle. The adjustment amount can also be displayed in real time on the computer, allowing the operator to monitor the adjustment progress promptly.

[0035] In this embodiment, the movable robotic arm 5 includes a control system and an adjustment system for the movable column to be adjusted. The control system is signal-connected to the control terminal 6 to control the adjustment system's actions according to the adjustment information sent by the control terminal 6, adjusting the column to be adjusted to a preset position and angle. The control system can communicate with a computer to obtain adjustment data and control the adjustment system to adjust the column. After adjustment, it sends information to the computer for the next measurement until the accuracy requirements are met. The adjustment device can perform six degrees of freedom adjustment on the column and provides real-time feedback on the adjustment amount until the parameters required by the control system are reached.

[0036] The mobile robotic arm 5 also includes a drive system and an energy storage system. The drive system enables the mobile robotic arm to move. The drive system can consist of common drive devices including wheels or tracks, a drive motor, a reducer, a steering mechanism, and a braking mechanism. Under the operation of professional personnel, it can enable the robotic arm to move freely until it reaches a designated position. The energy storage system provides power to the control system, adjustment system, and drive system. The mobile robotic arm 5 in this embodiment can be purchased commercially, as long as it meets the corresponding functions.

[0037] like Figure 2 As shown, in this embodiment, the structure and dimensions of the column to be adjusted 4 and the end column 2 are identical. During column installation, there is no need to distinguish the columns structurally; the column to be adjusted and the end column are determined only by their placement position, thus saving operator workload and effectively improving installation efficiency. The specific structure of the column is described below using the end column as an example: [Refer to...] Figure 2 The end column 2 has a bearing seat 7 installed at its top, and two support legs 8 at its bottom, both of which are connected to the ground via fixed feet. By providing two support legs 8, the support and balance of the column can be improved.

[0038] Specifically, the fixing foot has a fixing groove 9, the center of which is used to connect with the support leg 8. The fixing groove 9 has bolt holes symmetrically distributed along the support leg. In actual use, the bolts pass through the bolt holes and are fixed to the ground. By setting symmetrical bolt holes, the stability of the column after installation is improved.

[0039] When using the automatic detection and adjustment device for the column of this trough-type concentrator:

[0040] First, install the end column in place, then install the transmitter on the bearing seat of the end column. Preset the spacing between the column to be adjusted and the end column and the offset angle range of the bearing seat center point on the computer.

[0041] Simply fix the first column to be adjusted near the estimated position, and install the receiving end on the bearing seat of the column to be adjusted;

[0042] The computer controls the transmitter to emit laser signals. The computer then collects laser signal information from both the transmitter and receiver, calculates the adjustment information for the column to be adjusted, and the control system of the movable robotic arm communicates with the computer to obtain the adjustment data. It then controls the adjustment system to adjust the column. Once adjusted, it sends information to the computer to initiate the next laser signal emission, continuing until the required accuracy is met. A professional uses a torque wrench to tighten all locking nuts, completely fixing the column. A second measurement verifies if the accuracy requirements are met. If they are met, the installation and adjustment of this column is complete. If not, the above steps are repeated until the accuracy requirements are met. Then, the installation and adjustment of the next column begins.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
