Description

Technical Field

[0001] This utility model relates to the field of air-cooled island cleaning equipment, and more specifically, to an anti-entanglement self-moving transmission system for an air-cooled island fin cleaning device. Background Technology

[0002] In conventional designs, the triangular fins of air-cooled units in air-cooled islands must be equipped with cleaning devices and able to regularly wash the dust off the surface of the triangular fins with water to improve the heat exchange efficiency of the triangular fins, thereby reducing the back pressure of the unit and improving the economic efficiency of unit operation.

[0003] With continuous social progress and technological advancements, various cleaning technologies are now available. For cleaning large air-cooled tower heat exchangers, current cleaning technologies are mainly divided into two types: internal cleaning systems and external cleaning systems. Internal cleaning technology is installed inside the air-cooled tower, where cleaning media is sprayed from the inner side of the heat exchange tube bundle to the outer side. The vertical support is circumferentially moved by upper and lower guide rails and a suspended vertical frame inside the air-cooled tower. A cleaning trolley is installed on the vertical frame and moves along the vertical frame in the vertical direction of the cooling triangle to clean all the cooling triangular fins of the entire tower.

[0004] In internal cleaning technology, when the vertical frame moves circumferentially along the circular track inside the air-cooled island, the pipelines that provide the medium to the cleaning trolley and the power lines that supply power to the cleaning car need to move with the vertical frame. The problem of pipeline entanglement is difficult to solve. Currently, the common method is to manually drag the high-pressure hose and power cable along the vertical frame to ensure the passage of the medium pipelines and lines. This requires multiple people to operate and supervise. In summer, the temperature inside the island can even reach 80 degrees Celsius, which poses a safety hazard.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an anti-entanglement self-moving transmission system for an air-cooled island fin cleaning device, thereby avoiding the entanglement problem of pipelines under the vertical frame.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a vertical frame, the bottom of which travels on a track, a cable chain slot box is provided on one side of the track, a vertical cable chain is provided in the cable chain slot box, the hinge axis of the vertical cable chain link is arranged vertically, the chain body at both ends of the dynamic bending section of the vertical cable chain is close to the two side walls of the cable chain slot box, the movable end of the vertical cable chain is connected to the vertical frame, and the fixed end of the vertical cable chain is fixedly installed on the side wall of the cable chain slot box.

[0008] In this application, the vertical cable chain with vertically arranged links can dynamically bend and move in an orderly manner within the cable chain slot. The vertical cable chain restricts the movement range of the pipeline under the vertical frame to within the cable chain slot. Therefore, the pipeline can be driven by the vertical frame to bend and move in an orderly manner within the vertical cable chain, effectively preventing the pipeline from getting tangled when the vertical frame moves. It can ensure the pipeline's passage when automatically following the vertical frame, without requiring personnel to follow and drag the pipeline.

[0009] Based on the above, the vertical cable chain has at least two pipeline installation cavities arranged in upper and lower layers.

[0010] By installing the pipelines separately in the pipeline installation cavities that are arranged in upper and lower layers, interference can be avoided when the pipelines bend, thereby reducing the bending force of the vertical cable chain and the width of the cable chain groove box.

[0011] Based on the above, a single medium pipeline is provided in the pipeline installation cavity, and medium pipelines providing the same medium are located in different pipeline installation cavities.

[0012] By diverting the medium, the diameter of the medium pipeline can be effectively reduced while maintaining the same flow rate. This reduces the bending radius of the water supply pipeline, thereby further reducing the bending radius of the vertical cable chain and the width of the cable chain trough.

[0013] Based on the above, a transmission line is provided inside the pipeline installation cavity at the top.

[0014] In this way, power can be effectively supplied or data can be transmitted through the vertical cable chain, and the transmission line can also be prevented from being damaged by gravity.

[0015] Based on the above, the inner walls of the two side walls of the cable chain box are provided with first rollers, and the bottom of the vertical cable chain is provided with second rollers.

[0016] The first and second rollers effectively reduce the movement resistance between the vertical cable chain and the cable chain trough.

[0017] Based on the above, a cable chain connecting frame is installed at the bottom of the vertical frame, and the cable chain connecting frame is connected to the movable end of the vertical cable chain.

[0018] As an extension of the vertical frame, the cable chain connector can effectively move the vertical cable chain and connect the pipelines at the end of the vertical cable chain to the vertical frame, managing the pipelines in an orderly manner and further preventing pipeline entanglement.

[0019] Based on the above, the fixed end of the vertical cable chain is fixedly installed on either side wall of the cable chain slot box.

[0020] Thus, vertical cable chains have high adaptability. The installation side of the vertical cable chain can be adjusted according to the actual situation, so that it can adapt to various shapes of vertical racks and tracks, as well as the layout of other equipment in the air-cooled island.

[0021] Based on the above, a linear rail is provided on one side of the track, a line connecting frame is provided on the vertical frame, and a sliding contact line is provided between the linear rail and the line connecting frame.

[0022] By using a sliding contact line, the power supply cable can be effectively connected to the vertical rack, eliminating the need to install the power supply cable in the vertical cable chain, thus separating water and electricity and reducing the risk of accidents.

[0023] Based on the above, at least two sets of vertical cable chains are provided on one side of the track.

[0024] In this way, multiple sets of vertical cable chains can be set up according to the number of cleaning equipment to increase cleaning efficiency.

[0025] Based on the above, the cable chain slot is located inside the track.

[0026] This reduces the overall radius of the cable chain tray, which is beneficial for the movement of the vertical cable chain and reduces the risk of failure during the movement of the vertical cable chain. Attached Figure Description

[0027] Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 This is a schematic diagram of the overall structure of another embodiment of the present utility model; Figure 3 This is a top view of the cable chain slot box and vertical cable chain of this utility model.

[0028] In the figure, the attached reference numerals are: vertical frame 1, cable chain connecting frame 11, line connecting frame 12, track 2, cable chain trough box 3, first roller 31, vertical cable chain 4, pipeline mounting cavity 41, second roller 42, linear rail 5, and sliding contact line 6. Detailed Implementation

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0030] Example 1 like Figures 1-3 As shown, the anti-entanglement self-moving transmission system of the air-cooled island fin cleaning device in this embodiment includes a vertical frame 1. A lifting cleaning trolley can be provided on the vertical frame 1. The lifting cleaning trolley can clean the cooling triangular fins of the air-cooled island by moving up and down along the vertical frame 1.

[0031] The bottom of the vertical rack 1 travels on track 2, while the top of the vertical rack 1 generally needs to travel on another track.

[0032] One side of the track 2 is provided with an annular cable chain groove box 3. Since the track 2 is annular, the cable chain groove box 3 can also be set as an annular or segmented fan-shaped ring. The cable chain groove box 3 is provided with a vertical cable chain 4. The movable end of the vertical cable chain 4 is connected to the vertical frame 1, and the fixed end of the vertical cable chain 4 is fixedly installed on the side wall of the cable chain groove box 3.

[0033] Furthermore, the hinge axis of the links of the vertical cable chain 4 is arranged vertically, the dynamic bending section of the vertical cable chain 4 is arranged horizontally, and the chain bodies at both ends of the dynamic bending section of the vertical cable chain 4 are close to the two side walls of the cable chain trough 3, respectively. One section of the chain body, including the fixed end of the vertical cable chain 4, is attached to the side wall of the cable chain trough 3, while the other section of the chain body, including the movable end of the vertical cable chain 4, is moved by the vertical frame 1 and its movement range is limited by the two side walls. The cable carrier trough 3 includes a base plate and two side plates. The base plate is used to support the vertical cable carrier 4, and the two side plates are used to restrict the travel direction of the vertical cable carrier 4, so that the vertical cable carrier 4 can follow the vertical frame 1 along the track 2 by dynamic bending within the cable carrier trough 3, and the range of movement of the vertical cable carrier 4 is restricted within the cable carrier trough 3.

[0034] The vertical cable chain 4 can be equipped with pipelines, such as water hoses, power cables, and data cables, to provide cleaning media, power, and data exchange for the lifting cleaning trolley on the vertical rack 1. The cleaning media may include high-pressure water and high-pressure gas, and the water supply pipeline and gas supply pipeline can be made of high-pressure hoses.

[0035] The width of the cable chain trough 3 is calculated based on the bending radius of the hose. For example, if the bending radius of a DN50 pipe is 650mm, the trough width is designed to be 1350mm.

[0036] In this application, the vertical cable chain 4 with vertically arranged links can dynamically bend and move in an orderly manner within the cable chain slot 3. The vertical cable chain 4 restricts the movement range of the pipeline on the lower side of the vertical frame 1 within the cable chain slot 3. Therefore, the pipeline can be driven by the vertical frame 1 to dynamically bend and move in an orderly manner within the vertical cable chain 4, effectively preventing the pipeline from getting tangled when the vertical frame 1 moves. It can ensure the passage of the pipeline when automatically following the vertical frame 1, without the need for personnel to follow and drag the pipeline.

[0037] Example 2 Based on Embodiment 1, the vertical cable chain 4 has at least two pipeline installation cavities 41 arranged in upper and lower layers.

[0038] By installing the pipelines separately in the pipeline installation cavities 41 that are arranged in upper and lower layers, interference can be avoided when the pipelines bend, thereby reducing the bending force of the vertical cable chain 4 and the width of the cable chain trough 3.

[0039] Example 3 Based on Embodiment 2, a single medium pipeline is provided in the pipeline installation cavity 41, and medium pipelines providing the same medium are provided in different pipeline installation cavities 41.

[0040] For example, dividing the water supply pipeline into multiple pipelines can effectively reduce the diameter of the water supply pipeline while keeping the water flow rate constant. This reduces the bending radius of the water supply pipeline, thereby further reducing the bending radius of the vertical cable chain 4 and the width of the cable chain trough 3.

[0041] Example 4 Based on Embodiment 2 or Embodiment 3, a transmission line is provided inside the pipeline installation cavity 41 at the top.

[0042] like Figure 2 As shown, the power supply cable or data cable used for power supply or data transmission can be installed in the pipe mounting cavity 41 at the top of the vertical drag chain 4 to prevent the transmission line from being squeezed by gravity.

[0043] Example 5 Based on the above embodiments, the inner walls of the two side walls of the cable chain box 3 are provided with first rollers 31, and the bottom of the vertical cable chain 4 is provided with second rollers 42.

[0044] The first roller 31 can be a longitudinal guide roller. The longitudinal guide rollers are evenly spaced on the side wall of the cable tray box 3, so that the two ends of the dynamic bending section of the vertical cable chain 4 can contact the first roller 31 and slide relative to the side wall of the cable tray box 3, thereby reducing the resistance between them.

[0045] In practical applications, the chain body of the vertical cable chain 4, including its fixed end, is attached to the side wall of the cable chain trough 3 on one side of its dynamic bending section. This part of the chain body does not move relative to the side wall it is attached to, so there is no need to set the first roller 31.

[0046] The second roller 42 can be a ball bearing or a swivel wheel, allowing the vertical cable chain 4 and the bottom plate of the cable chain trough 3 to slide relative to each other, reducing the resistance between them.

[0047] Example 6 Based on the above embodiments, a cable chain connecting frame 11 is installed at the bottom of the vertical frame 1, and the cable chain connecting frame 11 is connected to the movable end of the vertical cable chain 4.

[0048] As an extension of the vertical frame 1, the cable chain connecting frame 11 can effectively drive the vertical cable chain 4 to move, and can connect the pipeline at the end of the vertical cable chain 4 to the vertical frame 1 through the cable chain connecting frame 11, so as to manage the pipeline in an orderly manner and further prevent the pipeline from getting tangled.

[0049] Example 7 Based on embodiment 6, through the extension effect of the cable chain connecting frame 11, the fixed end of the vertical cable chain 4 is fixedly installed on either side wall of the cable chain slot box 3, and the movable end of the vertical cable chain 4 can be dragged on either side wall of the cable chain slot box 3.

[0050] Thus, the vertical cable chain 4 has high adaptability. The installation side of the vertical cable chain 4 can be adjusted according to the actual situation, so that it can adapt to various shapes of vertical racks 1 and rails 2, as well as the layout of other equipment in the air-cooled island.

[0051] Example 8 Based on Embodiment 1 or Embodiment 4, a linear rail 5 is provided on one side of the track 2, a line connecting frame 12 is provided on the vertical frame 1, and a sliding contact line 6 is provided between the linear rail 5 and the line connecting frame 12.

[0052] The sliding contact line can adopt a multi-stage rainproof sliding contact line series. This series uses a semi-enclosed plastic conduit, which is made into a ring shape (encircling track 2) and has embedded multi-pole copper strips as power transmission conductors. The receiver has multi-pole brushes. For example, the marking line uses the DHG-5-50 type, and the receiver uses the JSD-5-50A type.

[0053] By using a sliding contact line, the power supply cable can be effectively connected to the vertical rack 1, eliminating the need to install the power supply cable in the vertical cable chain 4, thus separating water and electricity and reducing the risk of accidents.

[0054] Example 9 Based on the above embodiments, at least two sets of vertical cable chains 4 are provided on one side of the track 2. Depending on the number of vertical cable chains 4, the cable chain slot box 3 can be divided into multiple fan-shaped ring areas. Each fan-shaped ring area can be provided with a set of vertical cable chains 4. The pipelines between different sets of vertical cable chains 4 can be connected in parallel through rigid pipes to avoid tangling.

[0055] In this way, multiple sets of vertical cable chains 4 can be set according to the number of cleaning equipment to increase cleaning efficiency.

[0056] Example 10 Based on the above embodiments, the cable chain groove box 3 is located inside the track 2, which can reduce the overall radius of the cable chain groove box 3, which is beneficial to the movement of the vertical cable chain 4 and reduces the risk of failure during the movement of the vertical cable chain 4.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
