Description

Technical Field

[0001] This utility model relates to the field of power plant equipment technology, specifically to a steam-purged electric target plate device for power plants. Background Technology

[0002] Power plant equipment mainly includes two categories: main equipment and auxiliary equipment. The main equipment of a power plant includes boilers, steam turbines and generators.

[0003] After the installation or maintenance of a power plant boiler, steam blowing is required to ensure the cleanliness of the steam pipes and remove impurities such as welding slag and rust from the pipes.

[0004] In steam purging operations, target plates are required. Traditional target plates are mostly manually operated, requiring frequent manual replacement and inspection of their impact resistance during the purging process. This involves high temperatures, noise, severe communication interference, high labor intensity, and a high risk of burns. Furthermore, the untimely nature of manual operation affects the accuracy of purging effect evaluation and purging efficiency. This application proposes a target plate installation mechanism for installing target plates, a drive mechanism for driving the target plate shaft replacement, and a control system for controlling the operation of the entire device. This addresses the problems of high risk, high labor intensity, and low purging efficiency associated with manual operation of existing target plates, enabling remote control and automated target plate replacement during steam purging, thus avoiding dangers during target plate replacement. This invention proposes an electric target plate purging device for power plants. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electric steam purging target plate device for power plants. This solves the problem that manual target plate devices require on-site manual operation. During the purging process, due to high steam temperature, high pressure, high noise, and communication interference, it is difficult for on-site operators to coordinate the speed of target plate replacement with the control of boiler steam pressure, affecting the accuracy of purging effect evaluation and purging efficiency. At the same time, frequent manual replacement of target plates and inspection of their impact conditions result in high labor intensity and a high risk of burns.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric steam purging target plate device for power plants, comprising a target plate mounting mechanism, a drive mechanism, and a control system, wherein the target plate mounting mechanism is connected to the drive mechanism via a transmission connection.

[0007] The target plate mounting mechanism includes:

[0008] A detachable target plate is provided to adapt to steam pipes of different diameters by replacing the target plate.

[0009] The target plate holder is mounted to the target plate using slots and bolts.

[0010] A target plate shaft is mounted on the inner wall of the target plate frame, and the target plate is disposed at one end of the target plate shaft. The target plate shaft is used to drive the target plate to move.

[0011] The target plate shaft is connected to the drive mechanism, and the drive mechanism drives the target plate shaft to perform translational movement, thereby enabling rapid replacement of the target plate.

[0012] Preferably, the target plate is fixedly connected to the end of the target plate shaft by a slot and bolts.

[0013] Preferably, the drive mechanism includes a speed reducer, the output end of which is connected to a motor, and the drive mechanism uses a motor as a power source.

[0014] Preferably, the reducer has an internal transmission connection with a lead screw, and the motor drives the lead screw to rotate through the reducer.

[0015] Preferably, a connecting seat is fixedly connected to one end of the lead screw near the target plate shaft, and the connecting seat is fixedly connected to the end of the target plate shaft by bolts.

[0016] Preferably, it also includes an input module and an output module. The input module receives external command signals, and the output module sends drive signals to the drive mechanism to achieve the action target.

[0017] Furthermore, the beneficial effects of this utility model are as follows:

[0018] In use, the starting motor drives the lead screw to rotate via the reducer. The rotation of the lead screw causes it to move linearly, which in turn moves the target plate shaft connected to the lead screw via the connecting seat. This achieves linear translation of the target plate frame, allowing different target plates to enter the blowpipe position in sequence, thus achieving automatic target plate replacement. The entire process does not require frequent manual operation, significantly shortening the time interval for target plate replacement during blowpipe operation, enabling more continuous blowpipe operation, and improving overall blowpipe efficiency.

[0019] In addition, this utility model supports remote command reception and execution. Operators only need to perform simple remote control on the control system, which reduces labor intensity, improves the working environment, and eliminates the need for operators to be in close contact with high temperature and high pressure steam environment, thus reducing the risk of burns and mechanical injuries.

In the description of the embodiments of this utility model, unless otherwise stated, "multiple" means two or more.

[0023] like Figure 1 As shown, this utility model provides an electric steam purging target plate device for power plants.

[0024] Example 1:

[0025] According to the appendix Figure 1 As shown, it includes a target plate mounting mechanism 1 and a drive mechanism 2, with the target plate mounting mechanism 1 and the drive mechanism 2 being connected by a transmission.

[0026] Target plate mounting mechanism 1 includes:

[0027] The target plate 11 is replaceable, and can be adapted to steam pipes of different diameters by replacing the target plate 11.

[0028] The target plate holder 12 is mounted to the target plate 11 by means of slots and bolts;

[0029] The target plate shaft 13 is installed on the inner wall of the target plate frame 12. The target plate 11 is located at one end of the target plate shaft 13, and the target plate shaft 13 is used to drive the target plate 11 to move.

[0030] The target plate shaft 13 is connected to the drive mechanism 2. The drive mechanism 2 works together to drive the target plate shaft 13 to perform translational movement, thereby enabling the rapid replacement of the target plate 11.

[0031] The target plate holder 12 adopts a slot and bolt fixing design. Together with the drive mechanism 2, the target plate 11 can be quickly replaced without disassembling the flange, reducing downtime. Compared with traditional hydraulic or straight shaft target plate devices, the operation complexity is significantly reduced.

[0032] The target plate 11 is fixedly connected to the end of the target plate shaft 13 by a slot and bolts.

[0033] The drive mechanism 2 includes a reducer 21, and a motor is connected to the output end of the reducer 21.

[0034] The reducer 21 has an internal transmission connection to a lead screw 22, and the motor drives the lead screw 22 to rotate through the reducer 21.

[0035] The drive mechanism 2 uses an electric motor as a power source, and converts the rotational motion of the motor into the linear motion of the target plate frame 12 through a lead screw transmission.

[0036] A connecting seat 23 is fixedly connected to one end of the lead screw 22 near the target plate shaft 13. The connecting seat 23 is fixedly connected to the end of the target plate shaft 13 by bolts.

[0037] When the motor is started, the reducer 21 drives the lead screw 22 to rotate. Under the rotation of the lead screw 22, the lead screw 22 moves linearly, which in turn drives the target plate shaft 13 connected to the lead screw 22 through the connecting seat 23 to move, thereby realizing the linear translation of the target plate frame 12, so that different target plates 11 enter the blowpipe position in sequence.

[0038] The automatic replacement of the target plate 11 eliminates the need for frequent manual operation, significantly shortening the time interval between target plate replacements during the blowpipe process. This allows for more continuous blowpipe operations and improves overall blowpipe efficiency.

[0039] According to the appendix Figure 1 As shown, it also includes an input module and an output module. The input module receives command signals from the controller, shift leader, or operator, while the output module sends drive signals to the drive mechanism 2 to achieve the desired action.

[0040] When the control system receives the overall adjustment or shift leader command, it sends an instruction to the control system, and the drive mechanism 2 performs complementary actions according to the settings to replace the new target plate 11.

[0041] Meanwhile, the control system can also store and display the blowpipe data, making it convenient for operators to understand the blowpipe situation in real time;

[0042] The control system supports remote command reception and execution. Operators only need to perform simple remote control on the control system, which reduces labor intensity, improves the working environment, and eliminates the need for operators to be in close contact with high-temperature and high-pressure steam environments, thus reducing the risk of burns and mechanical injuries.

[0043] The specific implementation method of this utility model will be described below with reference to the specific operation steps:

[0044] Weld or bolt the target plate base to the predetermined position in the steam pipeline purging section, ensuring the base is level and secure. Install the electric target plate body onto the base and connect it to the target plate bracket via the drive shaft. Adjust the perpendicularity of the target plate 11 to the pipeline axis, and slowly open the steam valve to perform steam purging. Monitor the steam pressure and temperature parameters to ensure they meet the purging procedures. After purging, close the steam valve and control the target plate 11 to retract to its initial position to avoid equipment damage caused by prolonged exposure to high temperatures.

[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
