Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, and more specifically, to a collision-resistant guide support for process pipelines in solar thermal power plants. Background Technology

[0002] In the process system of a concentrated solar power (CSP) plant, process pipelines, as the core carriers for transporting media (such as heat transfer oil and steam), directly affect the plant's energy efficiency and reliability through their operational safety and stability. However, pipelines face multiple challenges in actual operating conditions:

[0003] Concentrated solar power (CSP) plant pipelines are typically located in open-air environments or complex equipment areas, and may be subject to accidental impacts due to natural factors (such as strong winds or falling objects) or human factors (such as collisions during equipment maintenance). Traditional pipeline supports are mostly rigid fixed structures, lacking energy-absorbing and buffering designs. When a collision occurs, the impact force acts directly on the pipeline body, which may lead to pipeline deformation, weld cracking, or even media leakage, causing downtime for maintenance or safety accidents.

[0004] During the operation of a concentrated solar power (CSP) plant, pipelines experience significant thermal expansion and contraction displacement due to changes in the medium temperature (e.g., from ambient temperature to above 300°C). Traditional support structures often employ fixed limiting methods for guidance, which can easily lead to jamming due to excessive frictional resistance during axial or radial movement of the pipeline, or even stress concentration, causing pipeline bending or support loosening. For example, some existing structures use bolts to fix the guide blocks. The sliding friction between the guide blocks and the pipeline surface increases resistance during pipeline movement, potentially leading to wear of the guide blocks and damage to the anti-corrosion coating on the pipeline surface over long-term operation, affecting the system's sealing performance and service life.

[0005] During thermal displacement, friction between the pipeline and the guide components of the support consumes energy and exacerbates component wear. Existing guide structures often employ rigid contact designs, such as direct contact between a metal slider and the pipeline. These designs have a high coefficient of friction and lack self-lubrication, increasing pipeline movement resistance and potentially causing material performance degradation due to localized overheating. Furthermore, high frictional resistance leads to additional stress in the pipeline system, affecting the stability of medium flow and indirectly reducing power plant energy efficiency.

[0006] Existing pipeline protection technologies have shortcomings in the coordinated design of collision avoidance and guidance functions:

[0007] Energy absorption and guiding functions are separated: most structures only focus on a single function, such as independently setting up anti-collision baffles or guide rails, without forming an integrated protection system. This results in the guide structure not being able to buffer synchronously during a collision, or the anti-collision components hindering the movement of the pipeline during thermal displacement.

[0008] Traditional support geometry (such as horizontal or vertical fixed support) is difficult to adapt to the complex spatial displacement requirements of pipelines. Especially when pipelines need to move in both directions (such as vertical and horizontal directions), structural failure is easily caused by excessive or insufficient constraints.

[0009] Therefore, a collision-resistant guide bracket for process pipelines in solar thermal power plants is proposed. Utility Model Content

[0010] In order to overcome the above-mentioned defects of the prior art, this utility model provides a collision-proof guide bracket for process pipelines in solar thermal power plants to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, this utility model provides the following technical solution: a collision-resistant guide bracket for process pipelines in a solar thermal power plant, comprising a fixed plate, supports symmetrically arranged on the fixed plate, multiple energy-absorbing components evenly arranged between two supports, the multiple energy-absorbing components being connected to two sliding components, and multiple guide components installed on each sliding component, the two sliding components and the multiple guide components forming a V-shaped structure, and the two sliding components jointly supporting the pipeline body.

[0012] Preferably, the energy-absorbing assembly includes a crossbar, a spring, and a first nut, wherein the spring is sleeved on the crossbar, and a first nut is provided at both ends of the crossbar.

[0013] Preferably, the sliding assembly includes a slide frame, sliding holes, a bottom plate, and a top plate. The bottom of the slide frame is provided with a plurality of sliding holes evenly distributed. A bottom plate is provided on one side of the slide frame. A top plate is provided parallel to the top of the bottom plate. A plurality of guide components are evenly installed between the bottom plate and the top plate.

[0014] Preferably, the crossbar is inserted through a sliding hole, and the spring is located between the two carriages.

[0015] Preferably, both the bottom plate and the top plate are provided with through holes, and the through holes on the bottom plate and the top plate are coaxially arranged.

[0016] Preferably, the guide assembly includes a support rod, a rotating cylinder, and a second nut. The support rod passes through a through hole in the bottom plate and the top plate and is fixed by two second nuts. The rotating cylinder is sleeved on the support rod between the bottom plate and the top plate.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. The energy-absorbing components include springs that compress upon impact, absorbing the impact force and reducing its intensity. This prevents the pipe body from being directly impacted, thus improving pipe protection.

[0019] 2. The rotating drum of the guide component can be rotated, which can guide the pipe body when it expands and contracts with heat, allowing the pipe to move freely up and down, avoiding the pipe being pinched. The rotating drum can also reduce friction when the pipe body moves on the rotating drum. When the pipe moves up and down along the surface of the rotating drum, the contact area can also be reduced, further reducing the friction during lifting and lowering. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] As attached Figure 1-5 The anti-collision guide bracket for the process pipeline of the solar thermal power plant shown includes a fixed plate 1. Supports 2 are symmetrically arranged on the fixed plate 1. Multiple energy-absorbing components 3 are evenly arranged between the two supports 2. The multiple energy-absorbing components 3 are connected to two sliding components 4. Multiple guide components 5 are installed on each sliding component 4. The two sliding components 4 and the multiple guide components 5 together form a V-shaped structure, and the two sliding components 4 together support the pipeline body 6.

[0028] In specific implementation, by fixing the fixing plate 1 below the pipe body 6, the two sliding components 4 jointly support the pipe body 6. Each guide component 5 is in contact with the surface of the pipe body 6. Thus, when a collision occurs, the sliding component 4 first contacts the colliding object and then slides along the energy-absorbing component 3. The energy-absorbing component 3 absorbs the collision force, thereby reducing the collision intensity. The two sliding components 4 move closer together, making the included angle smaller, and the pipe body 6 moves upward under the guidance of each guide component 5. The pipe body 6 is always between the two sliding components 4, thus avoiding direct collision with the pipe body 6 and improving the protection of the pipe body 6.

[0029] The energy-absorbing component 3 includes a crossbar 301, a spring 302 and a first nut 303. The spring 302 is sleeved on the crossbar 301, and the first nut 303 is provided at both ends of the crossbar 301.

[0030] The sliding assembly 4 includes a slide 401, sliding holes 402, a base plate 403, and a top plate 404. The slide 401 has a plurality of sliding holes 402 evenly distributed at its bottom. The base plate 403 is provided on one side of the slide 401. The top plate 404 is provided parallel to the top of the base plate 403. A plurality of guide assemblies 5 are evenly installed between the base plate 403 and the top plate 404.

[0031] The crossbar 301 is inserted through the sliding hole 402, and the spring 302 is located between the two slides 401.

[0032] In practice, the two slides 401 are supported by springs 302, so that the two slides 401 support the pipe body 6 in a V-shape. When the pipe body 6 expands and contracts due to heat, the guide components 5 guide the pipe body 6, so that the pipe body 6 can move freely up and down, thereby avoiding pipe damage. When subjected to external force collision, the springs 302 are compressed to absorb the collision force, thereby reducing the angle between the two slides 401 and allowing the pipe body 6 to rise, thereby avoiding direct collision of the pipe body 6 and reducing the impact of the collision force on the pipe body 6.

[0033] Both the bottom plate 403 and the top plate 404 are provided with through holes, and the through holes on the bottom plate 403 and the top plate 404 are coaxially arranged.

[0034] The guide assembly 5 includes a support rod 501, a rotating cylinder 502, and a second nut 503. The support rod 501 passes through the through holes opened on the bottom plate 403 and the top plate 404 and is connected and fixed by two second nuts 503. The rotating cylinder 502, which is located between the bottom plate 403 and the top plate 404, is sleeved on the support rod 501.

[0035] In practice, the support rods 501 are evenly arranged to limit the position of each rotating cylinder 502, so that the rotating cylinder 502 can rotate with each corresponding support rod 501. When the pipe body 6 is arranged, it can be pressed against each rotating cylinder 502 and move smoothly, reducing friction. When the pipe body 6 rises and falls along the surface of the rotating cylinder 502, the contact surface can be reduced, thereby further reducing the friction of rising and falling.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
