Description

Technical Field

[0001] This utility model relates to the field of condenser cleaning technology, and in particular to a cleaning structure for the inner wall of condenser pipes. Background Technology

[0002] With the continuous development of communication technology, the number of large data centers is increasing. After continuous operation, the internal temperature of large data centers can become excessively high. To ensure the safe operation of these centers, air conditioning equipment is necessary to lower the temperature. Regular cleaning of the air conditioning equipment is also required to ensure its proper functioning.

[0003] In existing technology, a flexible hose is inserted into the condenser piping to clean the inner wall of the condenser piping inside the air conditioning unit. Specifically, for example... Figure 1 As shown, a steel wire nylon sheath is wrapped around the outer wall of the hose 3000. The friction between the steel wire nylon sheath and the inner wall of the condenser pipe 2000 is used to clean the inner wall of the condenser pipe 2000. However, there are many bends in the condenser pipe 2000, and the hose 3000 easily gets stuck at these bends. Repeated pulling and re-pulling of the hose 3000 is required to get it through these bends, wasting time and reducing cleaning efficiency.

[0004] Therefore, there is an urgent need to invent a cleaning structure for the inner wall of condenser pipes to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning structure for the inner wall of condenser pipes, so as to achieve cleaning of the inner wall of the cooling pipes, which not only has a good cleaning effect, but also has high cleaning efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The condenser piping inner wall cleaning structure includes:

[0008] A support shaft, the support shaft being flexible and capable of extending into the condenser piping;

[0009] A rolling cleaning sleeve includes balls and connecting ropes. The connecting ropes are flexible and configured to string the balls together. Multiple connecting ropes are woven together into a cylindrical structure with a grid pattern. The cylindrical structure is sleeved on the axial outer periphery of the support shaft. The balls are rotatably connected to the connecting ropes and are configured to roll in contact with the inner wall of the condenser pipe.

[0010] As an option, there is an angle between the rotation axis of the ball and the axial direction of the support shaft.

[0011] As an optional solution, the multiple connecting ropes are divided into a first group and a second group. Each of the connecting ropes in the first group forms a closed loop. The multiple closed loops are arranged at intervals along a preset direction with the axial direction as the preset direction. Each closed loop is connected with multiple balls.

[0012] The connecting ropes of the second group are arranged circumferentially around the closed loop, and each connecting rope of the second group extends along the preset direction. The connecting ropes of the second group are configured to connect the multiple closed loops along the preset direction, which is parallel to the axial direction of the support shaft.

[0013] As an option, the surface of the ball is provided with grooves and / or protrusions.

[0014] Alternatively, the spacing between two adjacent balls may be greater than the diameter of the balls.

[0015] As an optional solution, the surface of the connecting rope is covered with an elastic protective layer.

[0016] As an alternative, the rolling cleaning sleeve has a first end and a second end arranged opposite each other along the axial direction. The first end has a sealing cap, and the second end has an opening. The support shaft extends into the rolling cleaning sleeve along the opening of the second end, and the portion of the support shaft close to the first end along the axial direction serves as the head extending into the condenser pipeline.

[0017] As an optional solution, the outer peripheral wall of the support shaft is provided with a plurality of positioning grooves, which are spaced apart along the axial direction of the support shaft and around the circumference of the support shaft, and each positioning groove accommodates one ball.

[0018] Alternatively, the connecting rope passes through the center of the ball, and the depth of the positioning groove does not exceed two-thirds of the radius of the ball.

[0019] Alternatively, the support shaft may have a through hole located at the center of the support shaft and extending along the axial direction.

[0020] The beneficial effects of this utility model are:

[0021] The condenser pipe inner wall cleaning structure provided by this utility model uses a flexible support shaft and multiple flexible connecting ropes woven together to form a cylindrical structure with a grid pattern. Each connecting rope is connected to a ball bearing, and the ropes and ball bearings are assembled into a rolling cleaning sleeve. This rolling cleaning sleeve is fitted onto the axial outer circumference of the support shaft. When the support shaft extends into the condenser pipe, the ball bearings inside the rolling cleaning sleeve can roll and contact the inner wall of the condenser pipe, thus cleaning the inner wall of the condenser pipe through this rolling contact. The cleaning effect on the inner wall of the pipe is good. Moreover, when the support shaft needs to pass through the curved part of the condenser pipe, the flexible support shaft can bend and deform along the extension direction of the condenser pipe. At the same time, the flexible connecting rope can also bend with the support shaft. In addition, the rolling contact between the ball and the inner wall of the condenser pipe can guide the bending of the support shaft and the connecting rope, so that the support shaft and the connecting rope can quickly pass through the curved part of the condenser pipe. This solves the problem that the support shaft is easy to get stuck when passing through the curved part of the condenser pipe, and greatly improves the cleaning efficiency of the inner wall of the condenser pipe.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] Large computer rooms often experience excessively high internal temperatures after continuous operation. To ensure operational safety, air conditioning equipment is necessary to lower these temperatures. Regular cleaning of the air conditioning equipment is required to maintain its proper function. Current technology utilizes flexible hoses inserted into the condenser piping to clean the inner walls of the condenser pipes. Specifically, for example... Figure 1 As shown, a steel wire nylon sheath is wrapped around the outer wall of the hose 3000. The friction between the steel wire nylon sheath and the inner wall of the condenser pipe 2000 is used to clean the inner wall of the condenser pipe 2000. However, there are many bends in the condenser pipe 2000, and the hose 3000 easily gets stuck at these bends. Repeated pulling and re-pulling of the hose 3000 is required to get it through these bends, wasting time and reducing cleaning efficiency.

[0034] To solve the above problems, such as Figures 2-4As shown, this embodiment provides a condenser pipe inner wall cleaning structure 1000 to clean the inner wall of the condenser pipe 2000. Specifically, the condenser pipe inner wall cleaning structure 1000 includes a support shaft 100 and a rolling cleaning sleeve 200. The support shaft 100 is flexible and can extend into the condenser pipe 2000. The rolling cleaning sleeve 200 includes balls 210 and connecting ropes 220. The connecting ropes 220 are flexible and configured to string the balls 210 together. Multiple connecting ropes 220 are woven together into a cylindrical structure with a grid of holes. The cylindrical structure is sleeved on the axial outer periphery of the support shaft 100. The balls 210 are rotatably connected to the connecting ropes 220, and the balls 210 are configured to roll in contact with the inner wall of the condenser pipe 2000.

[0035] The condenser pipe inner wall cleaning structure 1000 uses a flexible support shaft 100 and multiple flexible connecting ropes 220. These ropes are woven together into a cylindrical structure with a grid pattern, and each rope 220 is connected to a ball bearing 210. The ropes 220 and ball bearings 210 are assembled into a rolling cleaning sleeve 200, which is fitted onto the axial outer circumference of the support shaft 100. When the support shaft 100 extends into the condenser pipe 2000, the ball bearings 210 in the rolling cleaning sleeve 200 can roll and contact the inner wall of the condenser pipe 2000. This rolling contact between the ball bearings 210 and the inner wall of the condenser pipe 2000 achieves cleaning of the inner wall of the condenser pipe 2000. The cleaning effect on the inner wall of the condenser pipe 2000 is good. Moreover, when the support shaft 100 needs to pass through the curved part of the condenser pipe 2000, the flexible support shaft 100 can bend and deform along the extension direction of the condenser pipe 2000. At the same time, the flexible connecting rope 220 can also bend along with the bending of the support shaft 100. In addition, the rolling contact between the ball bearing 210 and the inner wall of the condenser pipe 2000 can also guide the bending of the support shaft 100 and the connecting rope 220, so that the support shaft 100 and the connecting rope 220 can quickly pass through the curved part of the condenser pipe 2000. This solves the problem that the support shaft 100 is easy to get stuck when passing through the curved part of the condenser pipe 2000, and greatly improves the cleaning efficiency of the inner wall of the condenser pipe 2000.

[0036] It should be noted that in this embodiment, the ball 210 is a sphere. In other embodiments, the ball 210 may also be a cylinder or an ellipsoid; this embodiment does not impose any specific limitation.

[0037] Understandably, during the process of the support shaft 100 extending into the condenser pipe 2000, the support shaft 100 moves along its own axial direction. To ensure the cleaning effect of the ball bearings 210 on the inner wall of the condenser pipe 2000, there is an angle between the rotation axis of the ball bearings 210 and the axial direction of the support shaft 100. By creating an angle between the rotation axis of the ball bearings 210 and the axial direction of the support shaft 100, the ball bearings 210 can rotate freely around their own rotation axis during the process of the support shaft 100 extending into the condenser pipe 2000 along its own axial direction, thereby ensuring rolling contact between the ball bearings 210 and the inner wall of the condenser pipe 2000. It should be noted that in this embodiment, the rotation axis of the ball bearings 210 relative to the support shaft 100 is perpendicular to the axial direction of the support shaft 100, that is, the angle between the rotation axis of the ball bearings 210 and the axial direction of the support shaft 100 is 90°. In other embodiments, the angle between the rotation axis of the ball bearing 210 and the axial direction of the support shaft 100 can be adjusted arbitrarily within a range greater than 0° and less than or equal to 90°, depending on actual needs. This embodiment does not impose specific limitations on this. Within a range greater than 0° and less than or equal to 90°, the larger the angle value, the better the rolling contact effect between the ball bearing 210 and the inner wall of the condenser pipe 2000.

[0038] As an optional solution, the multiple connecting ropes 220 are divided into a first group and a second group. Each connecting rope 220 in the first group forms a closed loop, and the multiple closed loops are arranged at intervals along a preset direction with the axial direction as the preset direction. Each closed loop is connected with multiple balls 210. The multiple connecting ropes 220 in the second group are arranged at intervals around the circumference of the closed loop. Each connecting rope 220 in the second group extends along a preset direction. The connecting ropes 220 in the second group are configured to connect multiple closed loops along the preset direction, and the preset direction is parallel to the axial direction of the support shaft 100. By dividing multiple connecting ropes 220 into a first group and a second group, each connecting rope 220 in the first group can form a closed loop. Multiple closed loops are arranged at intervals along a preset direction with the axial direction as the preset direction. The multiple connecting ropes 220 in the second group extend along the preset direction and are arranged at intervals around the axial direction of the closed loops. The multiple connecting ropes 220 in the second group connect multiple closed loops together, ensuring that the preset direction is parallel to the axial direction of the support shaft 100. This achieves the purpose of weaving multiple connecting ropes 220 together into a cylindrical structure with a grid of holes. This not only makes the axial direction of the cylindrical structure parallel to the axial direction of the support shaft 100, but also makes the rotation axis of the ball bearings 210 on the closed loop perpendicular to the axial direction of the support shaft 100.

[0039] It should be noted that, in this embodiment, as Figure 4 As shown, each closed loop contains 10 ball bearings 210 connected in series. In other embodiments, the specific number of ball bearings 210 connected in series in each closed loop can be adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0040] As an optional solution, the surface of the connecting rope 220 is covered with an elastic protective layer. By covering the surface of the connecting rope 220 with an elastic protective layer, the direct contact between the ball bearing 210 and the connecting rope 220 can be replaced with direct contact between the ball bearing 210 and the elastic protective layer. This solves the problem of short service life of the connecting rope 220 caused by direct contact between the ball bearing 210 and the connecting rope 220, improves the protection of the connecting rope 220, and extends its service life. It should be noted that in this embodiment, the elastic protective layer is made of rubber material. Rubber material has good elasticity, toughness, and wear resistance, resulting in a long service life. In other embodiments, the elastic protective layer can also be made of other elastic materials; this embodiment does not impose specific limitations.

[0041] Furthermore, to further improve the cleaning effect of the ball bearing 210 on the condenser pipe 2000, grooves and protrusions are provided on the surface of the ball bearing 210. By providing grooves and protrusions on the surface of the ball bearing 210, the surface roughness of the ball bearing 210 can be increased, increasing the friction between the ball bearing 210 and the inner wall of the condenser pipe 2000, thereby improving the cleaning effect on the inner wall of the condenser pipe 2000. It should be noted that, in this embodiment, the grooves and protrusions on the surface of the ball bearing 210 are arranged alternately and cover the entire surface of the ball bearing 210 to maximize the surface roughness of the ball bearing 210. In other embodiments, grooves or protrusions may be provided only on the surface of the ball bearing 210; this embodiment does not impose specific limitations.

[0042] Optionally, the distance between two adjacent balls 210 is greater than the diameter of the balls 210. By ensuring that the distance between two adjacent balls 210 is greater than the diameter of the balls 210, sufficient space can be provided between the two adjacent balls 210 to meet the bending requirements of the balls 210 following the support shaft 100. It should be noted that in this embodiment, the distance between two adjacent balls 210 is twice the diameter of the balls 210. In other embodiments, the distance between two adjacent balls 210 can also be adjusted within a range greater than the diameter of the balls 210 according to actual needs; this embodiment does not impose specific limitations.

[0043] Understandably, in actual operating scenarios, the smaller the bending radius of the condenser pipe 2000, the smaller the diameter of the ball bearing 210, so that multiple balls bearing 210 can be evenly distributed on the inner wall of the bent portion of the condenser pipe 2000, ensuring the normal operation of the balls bearing 210. This embodiment does not limit the specific diameter of the balls bearing 210.

[0044] In an optional embodiment, the rolling cleaning sleeve 200 has a first end and a second end arranged axially opposite to each other. The first end has a sealing cap, and the second end has an opening. A support shaft 100 extends into the rolling cleaning sleeve 200 through the opening at the second end, with the portion of the support shaft 100 axially close to the first end serving as the head extending into the condenser pipe 2000. By providing a sealing cap at the first end of the rolling cleaning sleeve 200 axially and an opening at the second end, allowing the support shaft 100 to extend into the rolling cleaning sleeve 200 through the opening at the second end, and with the portion of the support shaft 100 axially close to the first end serving as the head extending into the condenser pipe 2000, it is ensured that the rolling cleaning sleeve 200 and the support shaft 100 remain relatively fixed axially during the insertion of the support shaft 100 into the condenser pipe 2000, thus ensuring the normal operation of the condenser pipe inner wall cleaning structure 1000.

[0045] Optionally, such as Figure 4 As shown, the outer peripheral wall of the support shaft 100 is provided with a plurality of positioning grooves 120. These positioning grooves 120 are spaced apart along the axial direction of the support shaft 100 and circumferentially around it. Each positioning groove 120 accommodates one ball 210. By providing a plurality of positioning grooves 120 on the outer peripheral wall of the support shaft 100, and ensuring that each positioning groove 120 accommodates one ball 210, the positioning of the ball 210 can be achieved, improving the positioning stability of the support shaft 100 and the rolling cleaning sleeve 200. It should be noted that in this embodiment, the shape of the positioning groove 120 is adapted to the shape of the ball 210 to further improve the positioning stability of the ball 210.

[0046] As an optional solution, the connecting rope 220 passes through the center of the ball 210, and the depth of the positioning groove 120 does not exceed two-thirds of the radius of the ball 210. By ensuring that the depth of the positioning groove 120 does not exceed two-thirds of the radius of the ball 210, it is possible to ensure that the center of the ball 210 is outside the outer peripheral wall of the support shaft 100, thus avoiding interference between the connecting rope 220 and the support shaft 100. It should be noted that in this embodiment, the depth of the positioning groove 120 is half the radius of the ball 210. In other embodiments, the depth of the positioning groove 120 can be arbitrarily adjusted without exceeding two-thirds of the radius of the ball 210; this embodiment does not impose specific limitations.

[0047] In an alternative embodiment, the support shaft 100 has a through hole 110, which is located at the center of the support shaft 100 and extends axially. By providing an axially extending through hole 110 at the center of the support shaft 100, not only can the weight of the support shaft 100 be reduced, saving production costs, but it also facilitates the injection of cleaning agent along the through hole 110 during subsequent cleaning of the inner wall of the condenser pipe 2000, further improving cleaning convenience.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
