Description

Technical Field

[0001] This disclosure relates to the field of safety protection technology for thermal power plants, and in particular to a safety protection device for thermal power plants. Background Technology

[0002] A thermal power plant is a type of power plant that uses fossil fuels to burn and generate high-temperature, high-pressure steam to drive a steam turbine to generate electricity.

[0003] Safety is paramount in thermal power plants, and installing appropriate safety barriers is a crucial measure to ensure safety. Regular inspection and maintenance of the barriers' integrity and stability are also necessary to ensure their effectiveness. Under current technology, safety barriers are used to protect operating equipment within thermal power plants. The main reasons for using safety barriers in industrial environments such as thermal power plants include: 1. Safety: Safety barriers effectively isolate operating equipment from personnel, reducing the risk of misoperation or accidental collisions, thus protecting operator safety. 2. Preventing equipment damage: Safety barriers prevent external objects or personnel from accidentally contacting equipment, reducing the probability of impact or damage. 3. Improving work efficiency: Safety barriers clearly define safety zones, helping employees better identify hazardous areas, reducing accidents caused by distraction, and improving work efficiency. 4. Preventing foreign object intrusion: Safety barriers prevent foreign objects from entering the equipment operating area, avoiding equipment malfunctions or downtime caused by foreign objects. 5. Compliance with safety standards: Many industries have relevant safety standards and regulations requiring the installation of protective devices around specific equipment to ensure safety at the production site. 6. Emergency Response: In emergency situations, guardrails can act as barriers, reducing the possibility of accident spread and providing employees with more reaction time. In summary, installing guardrails can effectively improve the safety management level of thermal power plants, ensuring the normal operation of equipment and the safety of operators. Common guardrail structures, designed for mobility, typically have casters at the bottom. However, in practice, this requires manual pushing by staff, and it's difficult to maintain a straight line under the casters, compromising the safe distance between the guardrail and equipment. Therefore, improvements to existing technology are necessary. Utility Model Content

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0031] Example 1:

[0032] See Figures 1-4 As shown, this invention discloses a safety protection device for a thermal power plant, including a mounting base 100 and a guardrail 202; there are two mounting bases 100, which are arranged in parallel; the guardrail 202 is slidably mounted between the two mounting bases 100; each mounting base 100 is provided with a driving assembly for driving the guardrail 202 to move along the mounting base 100. Thus, the driving assembly can drive the guardrail 202 to move along the length direction of the mounting base 100. Specifically, the mounting base 100 includes a first guide rail 102 and a second guide rail 101 arranged in parallel, with the first guide rail 102 located above the second guide rail 101; a first guide block 104 is slidably mounted on the first guide rail 102, and a second guide block 103 is slidably mounted on the second guide rail 101.

[0033] The drive assembly includes a lead screw 110, a moving block 109, and a servo motor 108, see below. Figure 2 As shown; the lead screw 110 is arranged parallel to the first guide rail 102, and one end of the lead screw 110 is fixedly connected to the output shaft of the servo motor 108. When the servo motor 108 rotates, it can drive the lead screw 110 to rotate synchronously. The moving block 109 is threadedly engaged with the lead screw 110. Specifically, the moving block 109 is provided with a threaded hole, and the moving block 109 is sleeved on the lead screw 110 through the threaded hole and threadedly engaged with the lead screw 110. The movable block 109 is fixedly connected to the first guide block 104 and the second guide block 103; the guardrail 202 is fixedly connected to the first guide block 104 and the second guide block 103. When the servo motor 108 drives the lead screw 110 to rotate, the lead screw 110 drives the movable block 109 to move along the lead screw 110. Since the movable block 109 is fixedly connected to the guardrail 202 through the first guide block 104 and the second guide block 103, the guardrail 202 also moves along with it. At the same time, the guiding and limiting function of the first guide rail 102 and the second guide rail 101 can effectively prevent the guardrail 202 from rotating around the lead screw 110 during the movement.

[0034] When in use, the guardrail 202 is used to protect the internal equipment of the thermal power plant. When personnel regularly use the maintenance device to maintain the internal equipment of the thermal power plant, the personnel need to move the guardrail 202 to provide space for the maintenance device. Specifically, the servo motor 108 is started, which drives the lead screw 110 to rotate. The lead screw 110 drives the moving block 109 to move, which makes it easier to adjust the position of the guardrail 202.

[0035] After the personnel have used the maintenance device to inspect and maintain the equipment, the staff will start the servo motor 108 again to reverse the servo motor 108 and drive the guardrail 202 to move in a straight line in the opposite direction, adjusting the distance between the guardrail 202 and the equipment to facilitate the protection of the equipment.

[0036] Example 2:

[0037] This embodiment is a further improvement on embodiment 1. The parts that are the same as those in embodiment 1 will not be repeated. Only the improvements will be described.

[0038] To facilitate the installation and disassembly of the guardrail 202, the guardrail 202 and the mounting base 100 can be detachably connected. Specifically, the lead screw 110 is located between the first guide rail 102 and the second guide rail 101. The side of the first guide block 104 near the guardrail 202 and the side of the second guide block 103 near the guardrail 202 are fixedly connected by a connecting rod 201. Specifically, the first guide block 104, the second guide block 103 and the connecting rod 201 are fixedly connected by welding. The connecting rod 201 is provided with a slot. The connecting rod 201 is set vertically, and the slot is opened from the upper end of the connecting rod 201 along the length of the connecting rod 201.

[0039] A plug rod 203 that mates with the slot is fixedly welded onto the guardrail 202.

[0040] See Figure 3 As shown, the insert rod 203 is L-shaped. One end of the insert rod 203 is fixedly connected to the guardrail 202, and the other end is inserted into the slot of the corresponding connecting rod 201. In specific implementation, the upper end of the insert rod 203 is fixedly connected to the side of the guardrail 202 near the mounting base 100 by welding, and the lower end of the insert rod 203 is inserted into the slot of the corresponding connecting rod 201. To ensure that the guardrail 202 can be stably positioned between the two mounting bases 100 after the insert rods 203 on both sides of the guardrail 202 are engaged with the slots of the corresponding connecting rods 201, the fixing point of the insert rod 203 and the guardrail 202 can be set at a position close to the middle of the guardrail 202, and the engagement length of the insert rod 203 with the slot can be set to be longer.

[0041] To improve the connection strength between the pole 203 and the guardrail 202, a reinforcing strip 206 can be fixedly installed between the pole 203 and the guardrail 202. (See figure) Figure 1 As shown.

[0042] As one implementation method, see Figure 2 As shown, a first mounting plate 111 and a second mounting plate 112 are fixedly connected between the first guide rail 102 and the second guide rail 101. Specifically, the two ends of the first guide rail 102 and the second guide rail 101 are fixedly connected by the first mounting plate 111 and the second mounting plate 112, respectively. The lead screw 110 is rotatably installed between the first mounting plate 111 and the second mounting plate 112. Specifically, an adapter cylinder 114 is fixedly installed on the second mounting plate 112. A round shaft 115 is coaxially fixedly installed on one end of the lead screw 110. The end of the round shaft 115 away from the lead screw 110 is rotatably installed in the adapter cylinder 114. The other end of the lead screw 110 is fixedly connected to the output shaft of the servo motor 108. The housing of the servo motor 108 is fixedly installed on the first mounting plate 111.

[0043] To facilitate control of the servo motor 108, a controller 113 is fixedly mounted on the first mounting plate 111. The controller 113 is electrically connected to the servo motor 108. In specific implementations, one controller 113 can be set on each of the two mounting bases 100, and both controllers 113 are electrically connected to the servo motors 108 on the two mounting bases 100. Either controller 113 can simultaneously control the servo motors 108 on the two mounting bases 100 to work synchronously. Thus, if one controller 113 fails, the other controller 113 can still control the two servo motors 108 to work. Alternatively, only one controller 113 can be set on each of the two mounting bases 100, and the controller 113 is electrically connected to the servo motors 108 on both mounting bases 100, so that both servo motors 108 can be controlled simultaneously by this one controller 113.

[0044] Further, see Figures 3-4 As shown, mounting components are installed on both the first guide block 104 and the second guide block 103, and mounting grooves 116 are formed on both the first guide block 104 and the second guide block 103. The mounting components are installed in the corresponding mounting grooves 116. The mounting components include a third mounting plate 105, a connecting shaft 106, and a roller 107. The third mounting plate 105 is fixedly connected to the inner wall of the mounting groove 116. There are two third mounting plates 105, and the two third mounting plates 105 are arranged in parallel. The connecting shaft 106 is fixedly arranged between the two third mounting plates 105. The roller 107 is rotatably mounted on the connecting shaft 106.

[0045] The first guide rail 102 has a first guide groove 102a along its length, and the roller 107 of the mounting assembly located on the first guide block 104 can roll along the first guide groove 102a; the second guide rail 101 has a second guide groove 101a along its length, and the roller 107 of the mounting assembly located on the second guide block 103 can roll along the second guide groove 101a.

[0046] By setting up the installation components, the sliding of the first guide block 104 and the second guide block 103 can be assisted.

[0047] The guardrail 202 is equipped with warning lights 204; there are multiple warning lights 204, which are symmetrically arranged on opposite side walls of the guardrail 202. The warning lights 204 are provided to serve as warnings and reminders.

[0048] To facilitate the installation of the guardrail 202, auxiliary handles 205 can be fixedly installed on the guardrail 202. Two auxiliary handles 205 are provided and symmetrically arranged on the guardrail 202.

[0049] Equipment installed inside existing thermal power plants requires protection, necessitating the installation of guardrails. However, most existing guardrails are fixed, making them difficult for personnel to move. In practical applications, the guardrail described in this disclosure, driven by a drive component, can move linearly along a guide rail, further adjusting the distance between the guardrail and the equipment. This space allows for the installation of other thermal power plant equipment or facilitates routine maintenance and repair work. After maintenance, the guardrail can be restored to its initial position, demonstrating promising application prospects.
