Description

Technical Field

[0001] The utility model belongs to the technical field of condenser cleaning devices, and particularly relates to a cleaning device for condenser pipes. Background Art

[0002] A condenser is one of the important devices in the conventional island of a nuclear power plant. The quality of its working performance has a very important impact on the safety and economy of the entire unit. Improving and maintaining the best vacuum of the condenser is one of the ways to effectively reduce the power generation cost. There are many factors affecting the vacuum degree of the equipment, such as vacuum tightness, circulating water volume and water temperature, heat exchange pipe cleanliness factor, etc. Among them, the pipe cleanliness factor is an important influencing factor. The condenser uses circulating cooling water to cool another liquid or gas. Since the heat exchange tubes are directly connected to seawater for flow-through cooling, there are many impurities such as cooling water sediment and microorganisms, and there is different degrees of scale accumulation and microorganism reproduction, which seriously affects the pipe cleanliness, resulting in low heat exchange efficiency, and further causes the reduction of the equipment vacuum degree. Therefore, the unit often needs to reduce power operation or even stop to clean the heat exchange tubes.

[0003] At present, the relatively common condenser cleaning technology is to set up a climbing scaffold inside the condenser water chamber and manually guide a high-pressure water gun into the heat exchange tubes one by one for cleaning. However, the number of heat exchange tubes is large, the length is about 18m, and the pipe distribution is as Figure 1 Therefore, it will lead to limited working space, large labor intensity, and relatively long working time, affecting the maintenance efficiency of the entire unit.

[0044] Embodiment:

[0045] This embodiment provides a cleaning device for condenser pipes, which is used to solve the technical problem of low cleaning efficiency of the existing condenser cleaning device. The cleaning device for condenser pipes includes a bracket 1, a pipe 2, a first driving component 3, a second driving component 4, and a third driving component 6, wherein:

[0046] The bracket 1 includes a rectangular frame and support rods. The support rods are installed at the vertices of the rectangular frame. In the working state, the support rods are placed on a plane, and the rectangular frame is located directly in front of the condenser to be cleaned.

[0047] One end of the pipe 2 is movably installed on the bracket 1, and the other end of the pipe 2 is communicated with a water source, and the water source is a high-pressure water source.

[0048] The first driving component 3 is installed on the bracket 1. The first driving component 3 is used to drive the pipeline 2 to reciprocate in the first direction, and the first direction is the width direction of the rectangular frame. Through the setting of the first driving component 3, it is convenient to drive the pipeline 2 to reciprocate in the width direction of the rectangular frame.

[0049] The second driving component 4 is installed on the first driving component 3. The second driving component 4 is used to drive the pipeline 2 to reciprocate in the second direction. The first direction and the second direction are perpendicular to each other, and the second direction is the length direction of the rectangular frame. Through the setting of the second driving component 4, it is convenient to drive the pipeline 2 to reciprocate in the length direction of the rectangular frame. Through the cooperation of the first driving component 3 and the second driving component 4, it is convenient to move the pipeline 2 to any target point.

[0050] The third driving component 6 is installed on the second driving component 4, and the other end of the pipeline 2 is installed on the third driving component 6. The third driving component 6 is used to drive the pipeline 2 to extend into and withdraw from the heat exchange tube. In this way, through the setting of the third driving component 6, when the heat exchange tube needs to be cleaned, the third driving component 6 is used to drive the pipeline 2 to extend into the heat exchange tube to clean the inner wall of the heat exchange tube. After the cleaning is completed, the third driving component 6 is used to drive the pipeline 2 to withdraw from the heat exchange tube again.

[0051] With the above structure, when using the cleaning device for the condenser pipeline provided by the present utility model, first, the first driving component 3 is used to drive the pipeline 2 to move in the first direction until the pipeline 2 moves to the position corresponding to the heat exchange tube to be cleaned in the first direction. Then, the second driving component 4 is used to drive the pipeline 2 to move in the second direction until the pipeline 2 moves to the position corresponding to the heat exchange tube to be cleaned in the second direction, that is, the pipeline 2 is arranged opposite to the heat exchange tube to be cleaned. In this way, through the cooperation of the first driving component 3 and the second driving component 4, the pipeline 2 is moved to the target point, which is time-saving and labor-saving. Then, the water source is connected to make the pipeline 2 spray high-pressure water flow into the heat exchange tube, so as to achieve the purpose of cleaning the heat exchange tube. At the same time, the third driving component 6 is used to drive the pipeline 2 to move in the direction gradually approaching the heat exchange tube and extend into the heat exchange tube, so as to avoid poor cleaning effect due to insufficient pressure when cleaning the end of the heat exchange tube far from the bracket 1. After the heat exchange tube is cleaned, the third driving component 6 is used to drive the pipeline 2 to move in the direction gradually away from the heat exchange tube again, and then the above process is repeated until all the heat exchange pipelines 2 are cleaned. Therefore, through the cooperation of the first driving component 3, the second driving component 4 and the third driving component 6, the pipeline 2 is driven to the heat exchange tube to be cleaned, and the pipeline 2 is guided into the heat exchange tube for cleaning, so that the cleaning efficiency of the cleaning device for the condenser pipeline provided by the present utility model is higher.

[0052] An optional implementation manner of this embodiment is as follows: The first driving component 3 includes a first driving member 31, a first screw 32 and a mounting bracket 33, where:

[0053] One end of the first driving member 31 is mounted on the bracket 1, and the other end extends along the first direction.

[0054] One end of the first screw 32 is connected to the other end of the first driving member 31, and the other end of the first screw 32 is rotatably mounted on the bracket 1. The first driving member 31 is used to drive the first screw 32 to rotate. In this way, when the first driving member 31 rotates, it drives the first screw 32 to rotate together.

[0055] The mounting frame 33 is screwed onto the first screw 32, and both ends of the mounting frame 33 are slidably mounted on the bracket 1. Specifically, sliders are mounted at both ends of the mounting frame 33, and long grooves adapted to the sliders are formed in two opposite side walls of the U-shaped frame. The long grooves are arranged along the width direction of the U-shaped frame, and the two sliders are respectively slidably mounted in the two long grooves. When the screw rotates, the mounting frame 33 slides along the first direction on the bracket 1.

[0056] Optionally, the first driving member 31 and the first screw 32 form a set of transmission groups, and the number of transmission groups is two. The two transmission groups are arranged at intervals along the second direction. In this way, through the setting of multiple transmission groups, it is more convenient to drive the mounting frame 33 to move on the bracket 1, and the probability that the mounting frame 33 tilts during the movement and is stuck on the bracket 1 and cannot move is reduced.

[0057] An optional implementation manner of this embodiment is as follows: The second driving assembly 4 includes a second driving member 41, a second screw 42, and a mounting plate 43, where:

[0058] One end of the second driving member 41 is mounted on the mounting frame 33, and the other end of the second driving member 41 extends along the second direction.

[0059] One end of the second screw 42 is connected to the other end of the second driving member 41, and the other end of the second screw 42 is rotatably mounted on the mounting frame 33. The second driving member 41 is used to drive the second screw 42 to rotate. In this way, when the second driving member 41 rotates, it drives the second screw 42 to rotate together.

[0060] A chute 331 is formed in one side of the mounting frame 33. The chute 331 is arranged along the second direction. One end of the mounting plate 43 is slidably inserted into the chute 331 and is screwed onto the second screw 42. When the second screw 42 rotates, it drives the mounting plate 43 to move along the second direction in the chute 331.

[0061] Optionally, it further includes a plug-in block 5 fixedly installed on one side of the mounting plate 43. A threaded hole adapted to the second screw 42 is provided on the plug-in block 5. The threaded hole is arranged along the second direction. The plug-in block 5 is slidably inserted into the chute 331 and is screwed to the second screw 42. In this way, through the setting of the plug-in block 5, when the second screw 42 rotates, it drives the plug-in block 5 to reciprocate along the second direction in the chute 331, so that the mounting plate 43 fixedly installed with the plug-in block 5 reciprocates along the second direction.

[0062] An alternative implementation manner of this embodiment is as follows: The third driving assembly 6 includes a third driving member 61, a driving wheel 62 and a driven wheel 63, where:

[0063] One end of the third driving member 61 is installed on the mounting plate 43, and the other end extends along the first direction.

[0064] The driving wheel 62 is connected to the other end of the third driving member 61. The third driving member 61 is used to drive the driving wheel 62 to rotate. When the third driving member 61 rotates, it drives the driving wheel 62 to rotate synchronously.

[0065] The driven wheel 63 is rotatably installed on the mounting plate 43 and meshes with the driving wheel 62, that is, the axis of the driven wheel 63 is parallel to the axis of the driving wheel 62 and does not coincide. A through hole extending along the third direction is provided on the mounting plate 43. The pipeline 2 is slidably installed in the through hole, and the first section of the pipeline 2 is clamped between the driving wheel 62 and the driven wheel 63. The first direction, the second direction and the third direction are perpendicular to each other in pairs. In this way, when the driving wheel 62 rotates, it drives the driven wheel 63 to rotate synchronously, and uses the friction between the pipeline 2 and the driving wheel 62 and the driven wheel 63 to drive the pipeline 2 clamped between the driving wheel 62 and the driven wheel 63 to move towards or away from the bracket 1, so as to achieve the purpose of the pipeline 2 entering and exiting the heat exchange tube.

[0066] Optionally, the driving wheel 62 and the driven wheel 63 form a set of clamping groups, and the number of clamping groups and the number of pipelines 2 are multiple. The multiple pipelines 2 are arranged in one-to-one correspondence with the multiple clamping groups. In this way, through the setting of the multiple clamping groups and the multiple pipelines 2, multiple heat exchange pipelines 2 can be cleaned simultaneously, further improving the efficiency of cleaning the heat exchange tubes.

[0067] Optionally, the first driving member 31, the second driving member 41 and the third driving member 61 are all electric motors, which can provide stable rotational power and are easy to control.

[0068] An alternative implementation manner of this embodiment is as follows: It further includes a camera 7 installed on the mounting plate 43. In this way, through the setting of the camera 7, it is convenient to determine the position of the pipeline 2.

[0069] An alternative implementation of this embodiment is as follows: It further includes a controller, which is electrically connected to the first driving member 31, the second driving member 41, the third driving member 61, and the camera 7. In this way, through the setting of the controller, it is more convenient to control the on / off of the first driving member 31, the second driving member 41, the third driving member 61, and the camera 7.
