Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to a water conservancy project pipeline cleaning device. Background Art

[0002] Water conservancy pipelines refer to various pipeline systems used in water conservancy projects, which are mainly used to transport, distribute and control water flow to meet different water conservancy needs, such as irrigation, drainage, water supply and power generation. During the long-term operation of water conservancy pipelines, the inner wall of the pipelines is prone to accumulation of impurities such as silt, scale, microorganisms, etc., which leads to a decrease in the water flow capacity of the pipelines, or even blockage, affecting the normal operation of water conservancy facilities. Therefore, it is very important to regularly clean and maintain water conservancy pipelines.

[0003] At present, high-pressure water jet cleaning technology is one of the main means of cleaning pipelines in water conservancy projects. As the core component of high-pressure water jet cleaning technology, the performance of the high-pressure cleaning head directly affects the cleaning effect. The water outlet on the high-pressure cleaning head is set to be inclined so that the high-pressure water flowing out of the water outlet is sprayed toward the rear side of the high-pressure cleaning head, so that the high-pressure cleaning head can move forward under the reaction force of the high-pressure water flow. During the cleaning process, the high-pressure cleaning head ejects high-pressure water toward the inner wall of the pipe. Under the reaction force of the high-pressure water flow, the high-pressure cleaning head moves along the length of the pipe, and the high-pressure water flow impacts the inner wall of the pipe to remove attached solid particles and sediments. At the same time, the high-pressure water flow can flush the dirt on the inner wall of the pipe to the outside of the pipe.

[0004] Referring to the Chinese patent document with authorization announcement number CN217888333U and announcement date November 25, 2022, named "A kind of anti-blocking vibrating high-pressure cleaning nozzle", water is ejected through the high-pressure hole on the surface of the mouse head. When the water pressure is high, it will drive the entire cleaning head to vibrate. While vibrating, the brush in the cleaning mechanism will scrub the pipe wall, thereby cleaning the biofilm adsorbed on the pipe wall.

[0005] Referring to the Chinese patent document with authorization announcement number CN221548108U and announcement date August 16, 2024, entitled "A water conservancy pipeline for water conservancy projects", a cleaning component is arranged in the water conservancy pipeline, and the cleaning component includes a rotating column, and a plurality of groups of brushes are fixedly connected to one end of the surface of the rotating column, and the brushes rotate to clean the inner wall of the water conservancy pipeline.

[0006] With regard to the above-mentioned related technologies, the brush in the above-mentioned device can clean dirt with less adhesion from the inner wall of the pipe, but for some dirt with greater adhesion, the cleaning effect is poor and difficult to clean, especially for scale accumulated on the inner wall of the pipe for a long time. Under the impact of high-pressure water flow, the scale may partially fall off, but will form sharp or raised edges, which may get stuck in the cleaning head and restrict the movement of the cleaning head. At the same time, the high-pressure water flow will push the detached scale fragments to the back of the pipe. If these scale fragments are stuck between the cleaning head and the inner wall of the pipe, or accumulate on the uncleaned scale, it will further cause the cleaning head to be stuck. In this case, it is difficult for the high-pressure water flow to directly act on the scale that causes the cleaning head to be stuck, thereby affecting the normal operation and cleaning effect of the device. Summary of the invention

[0007] In view of this, the present invention provides a water conservancy project pipeline cleaning device, which aims to solve the technical problem in the prior art that when cleaning scale attached to the inner wall of the pipeline, the cleaning head is stuck by the scale, making it difficult for the cleaning head to move forward.

[0008] In order to solve the above technical problems, the present invention provides a water conservancy project pipeline cleaning device, which adopts the following technical solutions: a water conservancy project pipeline cleaning device, comprising a cleaning head, a pipe core and a water injection pipe connected in sequence from left to right, wherein a plurality of water outlet channels connected to the inside of the pipe core are provided in the cleaning head, a plurality of right outlets connected in sequence to the plurality of water outlet channels are provided on the circumferential side wall at the left end of the cleaning head, and water flows toward the right side at the right outlet; a rotating ring located on the right side of the right outlet is rotatably connected to the cleaning head, an annular channel is provided on the inner wall of the rotating ring, and the water outlet channel is connected to the ring through a water hole shaped channel is connected, a plurality of crushing columns are circumferentially arranged on the outer wall of the rotating ring, each crushing column is provided with a side outlet that can be connected with the annular channel, and the side outlet is inclined in the radial direction of the cleaning head; a control ring that slides left and right is provided between the inner wall of the rotating ring and the cleaning head, a sealing strip that can close the water hole between the annular channel and the water outlet channel is connected to the left side wall of the control ring, a plurality of baffle rods are circumferentially arranged on the right end of the control ring, the length of the baffle rod in the radial direction of the cleaning head is greater than the length of the crushing column in the radial direction of the cleaning head, and a compression spring is provided between the right side wall of the control ring and the cleaning head.

[0009] By adopting the above technical solution, when the device works normally, the water flows out to the right side of the cleaning head through the right outlet, and the cleaning head moves to the left under the reaction of the water flow. When the baffle rod contacts the scale on the inner wall of the pipe, the movement of the cleaning head is blocked, and the cleaning head moves to the left under the reaction of the high-pressure water flow, and the baffle rod contacts the scale, so that the baffle rod, the control ring and the sealing strip move to the right relative to the cleaning head, and the water hole between the annular channel and the water outlet channel is opened, so that the water flows through the water hole and the annular channel to the inner wall of the pipe around the pipe, and the scale near the baffle rod is cleaned with high pressure. At the same time, under the action of the high-pressure water flow, the rotating ring can be driven to rotate, and the crushing column collides with the scale and crushes the scale, and the scale on the inner wall of the pipe is cleaned, ensuring the cleaning effect of the device and the normal advancement of the cleaning head, so that the cleaning head can comprehensively clean the inner wall of the pipe.

[0010] A plurality of baffles are provided, and the baffles replace the cleaning head to contact the scale. The baffles can reduce the collision between the cleaning head and the inner wall of the pipe, and have a protective effect on the inner wall of the pipe and the cleaning head. The high-pressure water flow directly acts on the scale on the circumferential side wall of the cleaning head, which is convenient for cleaning the scale that hinders the movement of the cleaning head. In addition, a plurality of crushing columns are arranged circumferentially, and the side outlets are inclined. The crushing columns contact and break the scale, which can effectively break the scale that blocks the cleaning head from moving to the left, and can also expand the flushing range of the high-pressure water flow, which can improve the cleaning effect of the device and ensure the normal operation of the device.

[0011] Optionally, the circumferential side wall at the left end of the cleaning head is provided with a plurality of left outlets located on the left side of the right outlet and arranged circumferentially, the plurality of left outlets are connected with the plurality of water outlet channels in sequence, the left outlet is inclined from left to right toward the direction close to the central axis of the cleaning head, a crushing block is provided on the left side of the cleaning head, a compression spring 2 is provided between the crushing block and the cleaning head, a plurality of switching tubes are arranged circumferentially on the right side wall of the crushing block, the plurality of switching tubes are slidably inserted into the inner walls of the plurality of water outlet channels in sequence, a switching hole that can be connected with the left outlet is provided on the side wall of the switching tube, and the switching tube can close the right outlet.

[0012] By adopting the above technical solution, when the scale abuts against the left end of the cleaning head, the scale abuts against the crushing block, the compression spring 2 is compressed, the crushing block and the switching tube move to the right, the switching tube closes the right outlet, and the left outlet is connected to the water outlet channel through the switching hole. The water flow changes the channel and is ejected from the left outlet to the left side of the cleaning head, causing the cleaning head to move to the right under the reaction of the water flow. During the movement, the crushing block moves away from the cleaning head under the action of the compression spring 2, the switching tube is reset, the water restores the channel, and the water flow is ejected from the right outlet, causing the cleaning head to move to the left again, and this is repeated many times until the scale on the left side of the cleaning head is broken under the impact of the cleaning head and the high-pressure water flow ejected from the left outlet, and the cleaning head continues to move to the left and cleans the inner wall of the pipe.

[0013] Optionally, the tube core is slidably inserted into the cleaning head along the left-right direction.

[0014] By adopting the above technical solution, when the crushing block abuts against the scale, the cleaning head moves to the right, and the tube core and the cleaning head are slidably connected. During the rightward movement of the cleaning head, the cleaning head and the tube core move relative to each other, and the position of the water injection pipe remains almost unchanged, so that the reaction force of the subsequent water flow does not need to drive the water injection pipe to move. The reaction force of the water flow is only used to move the cleaning head to the left and collide with the scale, thereby increasing the impact force of the crushing head on the scale.

[0015] Optionally, the right side wall of the cleaning head is provided with a sliding groove extending in the left-right direction, the tube core is slidably inserted into the inner wall of the sliding groove, and the inner wall of the sliding groove is provided with an annular water injection cavity, which connects the interior of the tube core and the water outlet channel.

[0016] Optionally, a limit rod is provided between the left side wall of the sliding groove and the cleaning head, and the right end of the limit rod is inserted into the left end of the tube core in a sliding and plug-in manner, and the right end of the limit rod is connected to a protrusion that can abut against the left side wall of the internal cavity of the tube core.

[0017] By adopting the above technical solution, a limit rod is set to enhance the stability of the device.

[0018] Optionally, a limiting rod 2 is provided between the crushing block and the left side wall of the cleaning head, a through slot extending in the left and right directions is opened on the left side of the crushing block, the left end of the limiting rod 2 is inserted into the crushing block in a sliding manner, and the left end of the limiting rod 2 is connected to a protrusion that can abut against the right side wall of the through slot.

[0019] By adopting the above technical solution and setting a second limit rod, the stability of the device is improved.

[0020] Optionally, one end of the blocking rod away from the cleaning head is rotatably connected to a ball.

[0021] By adopting the above technical solution, the friction between the blocking rod and the inner wall of the pipeline is reduced, making it easier for the cleaning head to move.

[0022] Optionally, the left side wall of the crushing column is inclined from left to right in a direction away from the central axis of the cleaning head.

[0023] By adopting the above technical solution, it is ensured that the high-pressure water flow ejected from the right outlet acts on the inner wall of the pipe, and the conflict between the structures is avoided as much as possible.

[0024] Optionally, a plurality of the crushing columns and a plurality of the blocking rods are arranged in a staggered manner.

[0025] By adopting the above technical solution, the crushing columns and the baffle rods are arranged alternately. When the baffle rods abut against the scale, the crushing columns near the baffle rods can collide with the scale and crush the scale when they rotate, reducing the abutment between the scale and the crushing columns, which is beneficial to ensure the normal operation of the crushing columns.

[0026] Optionally, there are eight crushing columns.

[0027] By adopting the above technical solution, setting eight is a practical design choice that can achieve a good balance between fluid mechanics performance, structural strength, functional requirements and cost, and has versatility and maintainability.

[0028] In summary, the present invention includes the following beneficial technical effects: 1. A baffle is provided. The baffle replaces the cleaning head to contact the scale, which can reduce the collision between the cleaning head and the inner wall of the pipe and has a protective effect on the device. When the scale contacts the baffle, the outlet of the high-pressure water flow is changed so that the high-pressure water flow can impact the scale that blocks the movement of the cleaning head, and under the reaction of the high-pressure water flow, the rotating ring rotates, driving the crushing column to impact the scale, which can not only improve the crushing effect, but also expand the flushing range of the water flow, further improve the cleaning effect of the device, and ensure the normal operation of the device.

[0029] 2. When the scale contacts the left end of the cleaning head, change the outlet of the high-pressure water flow so that the high-pressure water flow is sprayed toward the scale on the left side of the cleaning head. Under the action of the reaction force of the water flow and the second compression spring, the cleaning head can move back and forth left and right and hit the scale, thereby improving the crushing effect of the device, ensuring the normal operation of the device, and improving the cleaning efficiency of the device.

[0030] 3. When breaking the scale on the left side of the cleaning head, the sliding setting of the tube core and the cleaning head can make the reaction force of the water flow no longer need to drive the water injection pipe to move. The reaction force of the water flow is only used to move the cleaning head to the left and collide with the scale, thereby increasing the impact force of the crushing head on the scale and improving the cleaning effect.

[0034] The embodiment of the present invention discloses a water conservancy project pipeline cleaning device. Figures 1 to 7 A water conservancy project pipeline cleaning device includes a cleaning head 1, a tube core 2, a water injection pipe 3, a water outlet channel 4, a right outlet 5, a side flow component 6 and a left flow component 7. The cleaning head 1 is sleeved on the left end of the tube core 2, the cleaning head 1 is connected to the inside of the tube core 2, the tube core 2 is connected to the water outlet end of the water injection pipe 3, and the high-pressure water flow enters the cleaning head 1 through the water injection pipe 3 and the tube core 2. Through the cooperation between the right outlet 5, the side flow component 6 and the left flow component 7, the cleaning head 1 can emit water flows in different directions from different positions in different scenes, so as to clean the inner wall of the pipeline and ensure the normal operation of the device.

[0035] Reference Figure 1 and Figure 2 The water outlet channel 4 extends in the left-right direction, and the plurality of water outlet channels 4 are evenly arranged along the circumference of the cleaning head 1. The plurality of water outlet channels 4 are all connected to the internal cavity of the tube core 2, and the water flow inside the tube core 2 flows into each water outlet channel 4. The right outlet 5 is opened on the circumferential side wall of the left end of the cleaning head 1, and the plurality of right outlets 5 are evenly arranged along the circumference of the cleaning head 1. The plurality of right outlets 5 correspond to and are connected to the plurality of water outlet channels 4 one by one.

[0036] Reference Figure 1 and Figure 2When the cleaning head 1 works normally, the water flows through the water injection pipe 3, the pipe core 2, the water outlet channel 4 and the right outlet 5 in sequence, and is ejected to the right side of the cleaning head 1. The water flows toward the inner wall of the pipe, which can clean the scale attached to the inner wall of the pipe. The cleaning head 1 moves to the left under the reaction force of the water flow.

[0037] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 In order to solve the problem that the scale in the pipeline abuts against the circumferential side wall of the cleaning head 1, making it difficult to move the cleaning head 1, the following structure is adopted: the side flow component 6 includes a rotating ring 61, an annular channel 62, a crushing column 63, a side outlet 64, a control ring 65, a sealing strip 66, a baffle rod 67 and a compression spring 68.

[0038] Reference Figure 2 and Figure 3 The rotating ring 61 is rotatably connected to the circumferential side wall of the right end of the cleaning head 1, and the annular channel 62 is opened on the inner wall of the rotating ring 61. Figure 3 The annular channel 62 is connected to the water outlet channel 4 through the water hole.

[0039] Reference Figure 6 and Figure 7 The crushing column 63 is connected to the outer wall of the rotating ring 61 , and multiple crushing columns 63 are evenly arranged along the circumference of the cleaning head 1 . The side outlet 64 is opened on the crushing column 63 , and the side outlet 64 is inclined in the radial direction of the cleaning head 1 . The side outlet 64 is connected to the annular channel 62 .

[0040] Reference Figure 6 and Figure 7 The control ring 65 is slidably inserted between the inner wall of the rotating ring 61 and the cleaning head 1 along the left and right directions, the sealing strip 66 is connected to the left side wall of the control ring 65, and multiple sealing strips 66 are evenly arranged along the circumference of the cleaning head 1. The sealing strip 66 can close the water hole between the annular channel 62 and the water outlet channel 4. The baffle rod 67 is connected to the right end of the control ring 65. There are multiple baffle rods 67 and they are evenly arranged along the circumference of the cleaning head 1. The length of the baffle rod 67 in the radial direction of the cleaning head 1 is greater than the length of the crushing column 63 in the radial direction of the cleaning head 1. A compression spring 68 is arranged between the right side wall of the control ring 65 and the cleaning head 1.

[0041] Since the device is provided with a baffle 67, the baffle 67 replaces the cleaning head 1 to abut against the scale, which can reduce the probability of the cleaning head 1 colliding with the inner wall of the pipeline, and has a protective effect on the cleaning head 1 and the inner wall of the pipeline. When the scale abuts against the baffle 67, as the cleaning head 1 moves to the left, the compression spring 68 is compressed, the control ring 65 moves to the right, the annular channel 62 is connected with the water outlet channel 4, the water flow changes the channel and is ejected from the side outlet 64, and the high-pressure water flow directly acts on the scale at the circumferential side wall of the cleaning head 1, which is convenient for cleaning the scale that hinders the movement of the cleaning head 1, and multiple crushing columns 63 are arranged circumferentially, and the side outlet 64 is inclined. Under the reaction force of the water flow, the rotating ring 61 rotates, and the crushing columns 63 abut against the scale and break the scale, which can effectively break the scale that blocks the movement of the cleaning head 1, ensuring the normal operation of the device. During the rotation of the rotating ring 61, the flushing range of the water flow can also be expanded, further improving the crushing effect of the water flow on the scale, and can improve the cleaning effect and cleaning efficiency of the device.

[0042] Reference Figure 2 and Figure 4 In order to solve the problem that the scale in the pipeline abuts against the left end of the cleaning head 1, making it difficult to move the cleaning head 1, the following structure is adopted: the left flow component 7 includes a left outlet 71, a breaking block 72, a compression spring 73, a switching tube 74 and a switching hole 75.

[0043] Reference Figure 2 , Figure 4 and Figure 5 The left outlet 71 is provided with a circumferential side wall of the left end of the cleaning head 1, and the left outlet 71 is located on the left side of the right outlet 5. The multiple left outlets 71 correspond to and are connected to the multiple water outlet channels 4 one by one, and the left outlet 71 is inclined from left to right toward the direction close to the central axis of the cleaning head 1.

[0044] Reference Figure 4 and Figure 6 The crushing block 72 is arranged on the left side of the cleaning head 1, the compression spring 73 is arranged between the crushing block 72 and the cleaning head 1, and the switching tube 74 is connected to the right side wall of the crushing block 72. Figure 4 and Figure 5 , multiple switching tubes 74 are evenly arranged along the circumference of the cleaning head 1, and the multiple switching tubes 74 correspond to the multiple water outlet channels 4 one by one. The switching tube 74 is slidably inserted into the inner wall of the water outlet channel 4, and the switching hole 75 is opened on the side wall of the switching tube 74. According to the different positions of the switching tube 74, the switching tube 74 can close the left outlet 71 or the right outlet 5. When the switching tube 74 is located on the left side, the side wall of the switching tube 74 closes the left outlet 71, and the right outlet 5 is connected to the water outlet channel 4. After the switching tube 74 moves to the right, the side wall of the switching tube 74 closes the right outlet 5, and the left outlet 71 is connected to the water outlet channel 4 through the switching hole 75.

[0045] When the scale abuts against the left end of the cleaning head 1, the scale abuts against the breaking block 72, the compression spring 2 73 is compressed, the breaking block 72 and the switching tube 74 move to the right, the switching tube 74 closes the right outlet 5, and the left outlet 71 is connected to the water outlet channel 4 through the switching hole 75. The water flow changes the channel and is ejected from the left outlet 71 to the left side of the cleaning head 1, causing the cleaning head 1 to move to the right under the reaction of the water flow. During the movement, the breaking block 72 moves away from the cleaning head 1 under the action of the compression spring 2 73, the switching tube 74 is reset, the water restores the channel, and the water flow is ejected from the right outlet 5, causing the cleaning head 1 to move to the left again, and this is repeated many times until the scale on the left side of the cleaning head 1 is broken under the impact of the cleaning head 1 and the high-pressure water flow ejected from the left outlet 71, and the cleaning head 1 continues to move to the left and cleans the inner wall of the pipeline.

[0046] Reference Figure 2 Furthermore, the tube core 2 is slidably inserted into the cleaning head 1 along the left-right direction. When the crushing block 72 contacts the scale, the cleaning head 1 moves to the right. The tube core 2 is slidably connected to the cleaning head 1. During the rightward movement of the cleaning head 1, the cleaning head 1 and the tube core 2 move relative to each other, and the position of the water injection pipe 3 remains almost unchanged, so that the reaction force of the subsequent water flow does not need to drive the water injection pipe 3 to move. The reaction force of the water flow is only used to move the cleaning head 1 to the left and collide with the scale, thereby increasing the impact force of the crushing block 72 on the scale.

[0047] Reference Figure 2 and Figure 3 Specifically, the right side wall of the cleaning head 1 is provided with a sliding groove 8 extending in the left-right direction, the tube core 2 is slidably inserted into the inner wall of the sliding groove 8, and the inner wall of the sliding groove 8 is provided with an annular water injection cavity 81, which connects the interior of the tube core 2 and the water outlet channel 4.

[0048] Reference Figure 2 and Figure 3 Furthermore, a limiting rod 9 is provided between the left side wall of the sliding groove 8 and the cleaning head 1, and the right end of the limiting rod 9 is inserted into the left end of the tube core 2 in a sliding and plugging manner, and the right end of the limiting rod 9 is connected with a protrusion that can abut against the left side wall of the internal cavity of the tube core 2.

[0049] Reference Figure 2 and Figure 3 Furthermore, a limiting rod 10 is provided between the crushing block 72 and the left side wall of the cleaning head 1. A through groove extending in the left and right directions is opened on the left side of the crushing block 72. The left end of the limiting rod 10 is inserted into the crushing block 72 in a sliding and plug-in manner. The left end of the limiting rod 10 is connected to a protrusion that can abut against the right side wall of the through groove.

[0050] Reference Figure 1 Furthermore, a ball is rotatably connected to one end of the stopper 67 away from the cleaning head 1, thereby reducing the friction between the stopper 67 and the inner wall of the pipeline, and facilitating the movement of the cleaning head 1.

[0051] Reference Figure 1 and Figure 2 Furthermore, the left side wall of the crushing column 63 is inclined from left to right in a direction away from the central axis of the cleaning head 1. It is ensured that the high-pressure water flow ejected from the right outlet 5 can act on the inner wall of the pipe, and the conflict between the structures is avoided as much as possible.

[0052] Reference Figure 1 and Figure 6 Furthermore, a plurality of crushing columns 63 and a plurality of baffles 67 are arranged in a staggered manner. When the baffles 67 contact the scale, the crushing columns 63 near the baffles 67 rotate to collide with the scale and crush the scale, thereby reducing the situation where the scale is stuck between the crushing columns 63 and the inner wall of the pipeline, which is conducive to ensuring the normal operation of the crushing columns 63.

[0053] Furthermore, eight crushing columns 63 are provided, and eight blocking rods 67 are provided. A good balance can be achieved between fluid mechanics performance, structural strength, functional requirements and cost, and the invention has versatility and maintainability.

[0054] The implementation principle of a water conservancy project pipeline cleaning device according to an embodiment of the present invention is as follows: When the cleaning head 1 works normally, water flows through the water injection pipe 3, the tube core 2, the water outlet channel 4 and the right outlet 5 in sequence, and is ejected to the right side of the cleaning head 1. The water flows toward the inner wall of the pipe, which can clean the scale attached to the inner wall of the pipe. The cleaning head 1 moves to the left under the reaction force of the water flow.

[0055] When the scale abuts against the baffle 67, as the cleaning head 1 moves to the left, the compression spring 68 is compressed, the control ring 65 moves to the right relative to the cleaning head 1, the annular channel 62 is connected with the water outlet channel 4, the water flow changes the channel and is ejected from the side outlet 64, and the high-pressure water flow directly acts on the scale on the circumferential side wall of the cleaning head 1 to facilitate cleaning. In addition, multiple crushing columns 63 are arranged circumferentially, and the side outlet 64 is inclined. Under the reaction force of the water flow, the rotating ring 61 rotates, and the crushing columns 63 abut against and break up the scale, which can improve the cleaning effect of the device.

[0056] When the scale abuts against the left end of the cleaning head 1, the scale abuts against the crushing block 72, the compression spring 2 73 is compressed, the crushing block 72 and the switching tube 74 move rightward relative to the cleaning head 1, the switching tube 74 closes the right outlet 5, and the left outlet 71 is connected to the water outlet channel 4 through the switching hole 75. The water flow changes the channel and is ejected from the left outlet 71 to the left side of the cleaning head 1. The water flow flushes the scale on the left side of the cleaning head 1. At the same time, the cleaning head 1 moves to the right under the reaction of the water flow. During the movement, the crushing block 72 moves to the left relative to the cleaning head 1 under the action of the compression spring 2 73, the switching tube 74 is reset, and the water flow is ejected from the right outlet 5, causing the cleaning head 1 to move to the left again. The crushing block 72 hits the scale again, and this is repeated many times until the scale on the left side of the cleaning head 1 is broken under the impact of the cleaning head 1 and the high-pressure water flow ejected from the left outlet 71, and the cleaning head 1 continues to move to the left and cleans the inner wall of the pipeline.

[0057] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense.
