Description

Technical Field

[0001] This invention belongs to the field of cooler anti-clogging, specifically a structure for preventing clogging in a tram cooler. Background Technology

[0002] A cooler is a type of heat exchange device used to cool fluids. Water or air is typically used as the coolant to remove heat. The coolers found on trams usually use water cooling to dissipate heat from the battery, ensuring that the battery does not overheat during tram operation.

[0003] A cooler typically consists of two sets of water pipes, an inlet, an outlet, and connecting pipes. During operation, the heated coolant enters the upper water pipe through the inlet, then flows through the aluminum connecting pipe into the lower water pipe, and is subsequently discharged from the outlet. The aluminum connecting pipe can absorb the heat of the coolant, thus achieving a cooling effect.

[0004] In existing technologies, after the coolant is repeatedly heated and cooled through the aluminum connecting pipe, scale will be produced and adhere to the inner wall of the aluminum connecting pipe. If it is not treated in time, long-term accumulation may cause blockage of the cooler's outlet or inlet, thereby affecting the circulation rate of the coolant, greatly reducing the heat dissipation effect of the cooler, and even affecting the normal operation of the tram. In addition, common cleaning devices can only clean the upper and lower water pipes and cannot clean the connecting pipes of the cooler.

[0005] Therefore, the present invention provides an anti-clogging structure for a tram cooler. Summary of the Invention

A first connecting plate is threadedly connected to the outer wall of the threaded rod. Multiple sets of second connecting rods are fixedly connected to the lower surface of the first connecting rod. Each second connecting rod corresponds to a connecting pipe. Multiple sets of second connecting rods are respectively arranged in multiple sets of connecting pipes. A second cleaning wipe is fixedly connected to the four sides of each second connecting rod by a spring rod. A drive motor is fixedly connected to the lower surface of the water inlet chamber. The output shaft of the drive motor is fixedly connected to the turntable.

[0008] Preferably, multiple sets of limiting rods are fixedly connected between the upper and lower inner walls of the water inlet chamber, and multiple sets of through holes are opened on the top of the first connecting plate. Each through hole corresponds to a limiting rod, and the multiple sets of limiting rods are respectively arranged in the multiple sets of through holes. The size of the through holes is adapted to the size of the limiting rods.

[0009] Preferably, the two sets of first connecting rods are located on the upper and lower sides of the outer surface of the vertical rod, and the outer surface of the first connecting rod near the inner wall of the water inlet is fixedly connected with a first cleaning wiper.

[0010] Preferably, the bottom inner wall of the water outlet chamber has multiple sets of limiting grooves, and each limiting groove has a limiting block slidably installed in it. The top of the limiting block is fixedly connected to a second connecting plate. The bottom of the two sets of second connecting rods near the water inlet pipe and the water outlet pipe is fixedly connected to a connecting block. The outer wall of the two sets of connecting blocks away from the water outlet pipe is hinged to a push rod. The end of the push rod away from the connecting block is hinged to the upper surface of the first connecting plate. The outer wall of the second connecting plate is fixedly connected to multiple sets of connecting frames. The outer surface of the connecting frames near the inner wall of the water outlet chamber is fixedly connected to a third cleaning wiper by a spring rod.

[0011] Preferably, the multiple sets of connecting frames are equidistantly distributed, and the second connecting plate is slidably installed inside the water outlet chamber.

[0012] Preferably, a first spring is fixedly connected to the inner wall of each limiting groove on the side away from the water outlet pipe, and the other end of the first spring is fixedly connected to the outer surface of the limiting block.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The anti-clogging structure of the electric vehicle cooler of the present invention involves the reciprocating motion of a first connecting plate and a threaded rod, causing a second connecting rod at the bottom of the first connecting plate to reciprocate within a connecting pipe. A first cleaning wipe is fixedly connected to the outer wall of the second connecting rod to clean the inner wall of the connecting pipe, preventing scale buildup and condensation on the inner wall of the connecting pipe after repeated heating and cooling of the coolant through the aluminum connecting pipe. This reduces scale formation and prevents long-term scale accumulation from clogging the cooler's outlet or inlet, thus affecting the coolant's circulation rate.

[0017] 2. The anti-clogging structure for a tram cooler described in this invention uses the reciprocating motion of the second connecting rod to drive the second connecting plate to reciprocate within the water outlet chamber. This, in turn, causes the connecting frame connected to the outside of the second connecting plate and the third cleaning brush to reciprocate within the water outlet chamber, thereby cleaning the inner wall of the water outlet chamber. This prevents scale from accumulating and condensing on the inner wall of the water inlet chamber due to prolonged uncleanliness, thus avoiding the situation where scale accumulates and clogs the water outlet during subsequent use.

[0018] 3. The anti-clogging structure of the electric vehicle cooler described in this invention uses an L-shaped hook to reset under the elastic restoring force of the second spring and impact the filter screen to prevent scale from adhering to the filter screen and causing blockage of the water inlet. When the L-shaped hook impacts the filter screen, the scale adhering to the filter screen will be shaken apart, thereby reducing the volume of the scale and further preventing blockage of the water inlet.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1

[0032] like Figures 1 to 5As shown in the figure, an anti-clogging structure for a tram cooler according to an embodiment of the present invention includes a water inlet chamber 1. Multiple sets of connecting pipes 6 are fixedly connected to the bottom of the water inlet chamber 1. A water outlet chamber 2 is fixedly connected to the bottom of each connecting pipe 6. A water inlet pipe 3 is fixedly connected to one outer wall of the water inlet chamber 1. A water outlet pipe 4 is fixedly connected to the outer wall of the water outlet chamber 2 on the side away from the water inlet pipe 3. A turntable 7 is rotatably connected to the side of the water inlet chamber 1 closest to the water inlet pipe 3. A hinge rod 8 is hinged to the top of the turntable 7 on the side away from its center. A horizontal bar 9 is hinged to the end of the hinge rod 8 away from the turntable 7. Vertical bars 10 are fixedly connected to both ends of the horizontal bar 9. Two sets of first connecting rods 11 are fixedly connected to the outer wall of each vertical bar 10 on the side away from the turntable 7. The water inlet chamber 1... A threaded rod 15 is rotatably connected between the inner walls of the upper and lower sides. A central gear 14 is fixedly connected to the outer wall of the threaded rod 15. A rack 13 is fixedly connected to the outer wall of one of the multiple sets of first connecting rods 11. The rack 13 meshes with the central gear 14. A first connecting plate 16 is threadedly connected to the outer wall of the threaded rod 15. Multiple sets of second connecting rods 17 are fixedly connected to the lower surface of the first connecting rod 11. Each second connecting rod 17 corresponds to a connecting pipe 6. Multiple sets of second connecting rods 17 are respectively arranged in multiple sets of connecting pipes 6. A second cleaning wipe 18 is fixedly connected to the four sides of each second connecting rod 17 by a spring rod. A drive motor 5 is fixedly connected to the lower surface of the water inlet chamber 1. The output shaft of the drive motor 5 is fixedly connected to the turntable 7.

[0033] To clean the connecting pipe 6 inside the cooler, the drive motor 5 is turned on when the tram is in use. The output shaft of the drive motor 5 drives the turntable 7 to rotate. The rotating turntable 7 drives the horizontal bar 9 to reciprocate within the water inlet chamber 1 via the hinge rod 8. During the movement of the horizontal bar 9, the vertical bar 10 and the first connecting rod 11 also reciprocate within the water inlet chamber 1. At this time, during the movement of the first connecting rod 11, which is equipped with a rack 13, the rack 13 on its outer wall drives the central gear 14 to rotate through the gear rotation. Since the first connecting rod 11 reciprocates under the action of the horizontal bar 9, it drives the central gear 14 to rotate in both directions, thereby driving the threaded rod 15 on its outer wall to rotate in both directions. During the rotation of the reciprocating threaded rod 15, the threaded rod 15 will... The transmission drives the first connecting plate 16 to reciprocate up and down, causing the second connecting rod 17 at the bottom of the first connecting plate 16 to reciprocate up and down inside the connecting pipe 6. At this time, the first cleaning wipe 12 is fixedly connected to the outer wall of the second connecting rod 17, which can clean the inner wall of the connecting pipe 6. This prevents scale from adhering to the inner wall of the connecting pipe 6 after the coolant is repeatedly heated and cooled through the aluminum connecting pipe 6, thus reducing scale formation and preventing the outlet or inlet of the cooler from becoming blocked due to long-term scale accumulation, which would affect the circulation rate of the coolant. Furthermore, since the first cleaning wipe 12 is connected to the second connecting rod 17 through a spring rod, the first cleaning wipe 12 will fit tightly against the inner wall of the connecting pipe 6 under the action of the spring force inside the spring rod, thereby improving the cleaning effect of the first cleaning wipe 12.

[0034] like Figures 7 to 9 As shown, multiple sets of limiting rods 19 are fixedly connected between the upper and lower inner walls of the water inlet chamber 1. Multiple sets of through holes 20 are opened on the top of the first connecting plate 16. Each through hole 20 corresponds to one of the limiting rods 19. The multiple sets of limiting rods 19 are respectively arranged in the multiple sets of through holes 20. The through holes 20 and the limiting rods 19 are adapted to each other in size. When the first connecting plate 16 moves up and down, the limiting rods 19 can limit it to prevent the first connecting plate 16 from rotating synchronously due to excessive friction between the first connecting plate 16 and the threaded rod 15. This also prevents the second connecting rod 17 at the bottom of the first connecting plate 16 from being misaligned, thus ensuring the cleaning effect of the second cleaning wipe 18 on the outer wall of the second connecting rod 17.

[0035] like Figures 3 to 6As shown, the two sets of first connecting rods 11 are located on the upper and lower sides of the outer surface of the vertical rod 10, respectively. The outer surface of the first connecting rod 11 near the inner wall of the water inlet chamber 1 is fixedly connected with a first cleaning wiper 12. After the drive motor 5 is turned on, it will drive the turntable 7 to rotate. The turntable 7 will drive the horizontal rod 9, the vertical rod 10 and the first connecting rod 11 to reciprocate synchronously through the hinge rod 8. At this time, the first cleaning wiper 12 set on the outer wall of the first connecting rod 11 will clean the inner wall of the water inlet chamber 1 and remove the scale that may be attached to the inner wall of the water inlet chamber 1. This will prevent the scale from settling and condensing into large pieces on the inner wall of the water inlet chamber 1 due to prolonged uncleanliness, and avoid the situation where the outlet or inlet of the cooler is blocked by large pieces of scale.

[0036] like Figures 7 to 8 As shown, the bottom inner wall of the water outlet chamber 2 has multiple sets of limiting grooves 25, and each limiting groove 25 is slidably installed with a limiting block 24. The top of the limiting block 24 is fixedly connected to a second connecting plate 23. Among the multiple sets of second connecting rods 17, the bottom of the two sets of second connecting rods 17 near the water inlet pipe 3 and the water outlet pipe 4 is fixedly connected to a connecting block 21. The outer wall of the two sets of connecting blocks 21 away from the water outlet pipe 4 is hinged with a push rod 22. The end of the push rod 22 away from the connecting block 21 is hinged to the upper surface of the first connecting plate 16. The outer wall of the second connecting plate 23 is fixedly connected with multiple sets of connecting frames 27. The outer surface of the connecting frames 27 near the inner wall of the water outlet chamber 2 is fixedly connected to a third cleaning wipe 28 by a spring rod.

[0037] In the initial state, the connecting block 21 is located inside the water outlet chamber 2. During the reciprocating movement of the second connecting rod 17, when the second connecting rod 17 moves upward, it will drive the connecting block 21 to move into the connecting pipe 6. As the connecting block 21 moves, the side wall of the connecting pipe 6 will contact the outer surface of the push rod 22. As the connecting block 21 continues to move, it will push the push rod 22 towards the connecting block 21. At this time, the push rod 22 will drive the second connecting plate 23 at its bottom to move towards the outlet pipe side.

[0038] When the second connecting rod 17 moves downward, it will drive the connecting block 21 to move downward and gradually detach from the connecting pipe 6. During the movement of the connecting block 21, the side wall of the connecting pipe 6 will gradually stop squeezing the push rod 22. At this time, the push rod 22 will move away from the water outlet pipe 4 under the pressure of the connecting block 21, thereby driving the second connecting plate 23 hinged at its bottom to move at the same time. Through the up and down reciprocating movement of the second connecting rod 17, the second connecting plate 23 will reciprocate in the water outlet chamber 2, thereby driving the connecting frame 27 and the third cleaning wipe 28 connected to the outside of the second connecting plate 23 to reciprocate in the water outlet chamber 2, thereby cleaning the inner wall of the water outlet chamber 2, preventing the scale from settling and condensing on the inner wall of the water inlet chamber 1 due to long-term uncleanliness, and avoiding the situation where the scale accumulates more and more during subsequent use, causing the water outlet to become blocked.

[0039] like Figures 7 to 8 As shown, multiple sets of connecting frames 27 are equidistantly distributed, and the second connecting plate 23 is slidably installed inside the water outlet chamber 2. The equidistantly distributed connecting frames 27 can increase the cleaning range of the inner wall of the water outlet chamber 2, thereby improving the cleaning effect.

[0040] like Figure 8 As shown, each of the limiting grooves 25 has a first spring 26 fixedly connected to the inner wall of the side away from the water outlet pipe 4. The other end of the first spring 26 is fixedly connected to the outer surface of the limiting block 24. Initially, the first spring 26 is in a compressed state. When the connecting block 21 moves into the connecting pipe 6, the push rod 22 will drive the second connecting plate 23 to move towards the side of the water outlet pipe 4 and stretch the first spring 26 under the pressure of the side wall of the connecting pipe 6. When the connecting block 21 moves outward from the connecting pipe 6, the side wall of the connecting pipe 6 no longer presses the push rod 22. At this time, the push rod 22 will move away from the water outlet pipe 4 under the action of the elastic restoring force of the first spring 26, thereby improving the smoothness of the movement of the second connecting plate 23.

[0041] like Figure 7 As shown, a filter screen 33 is fixedly connected inside the water inlet pipe 3. The filter screen 33 is adapted to the size of the water purification pipe. The filter screen 33 is made of high temperature resistant material. The filter screen 33 installed in the water inlet pipe 3 can filter out scale, preventing scale from entering the water inlet chamber 1 and adhering to the inner walls of the water inlet chamber 1, connecting pipe 6 and water outlet chamber 2 with the water flow, increasing the difficulty of cleaning. In addition, since the filter screen 33 is made of high temperature resistant material, it can avoid damage to the filter screen 33 due to excessively high temperature of the coolant, ensuring the fixing effect of the filter screen 33.

[0042] like Figures 2 to 3As shown, an L-shaped hook 29 is hinged to the inner wall of the water inlet chamber 1 near the water inlet pipe 3. A protrusion 31 is fixedly connected to the side of the L-shaped hook 29 near the turntable 7. A pressing rod 32 is fixedly connected to the top of the turntable 7. A second spring 30 is fixedly connected to the outer surface of the L-shaped hook 29. The end of the second spring 30 away from the L-shaped hook 29 is fixedly connected to the inner wall of the water inlet chamber 1. In the initial state, the end of the L-shaped hook 29 is in contact with the filter screen 33. During the rotation of the turntable 7, the pressing rod 32 on its top will rotate synchronously. During the rotation, the pressing rod 32 will contact the outer surface of the protrusion 31. As the turntable 7 continues to rotate, the squeezing rod 32 will squeeze the protrusion 31 and drive the L-shaped hook 29 to rotate. The end of the L-shaped hook 29 will separate from the filter screen 33 and compress the second spring 30. When the squeezing rod 32 rotates to disengage from the protrusion 31, the L-shaped hook 29 will reset under the elastic restoring force of the second spring 30 and impact the filter screen 33 to prevent scale from adhering to the filter screen 33 and causing the inlet to become blocked. When the L-shaped hook 29 impacts the filter screen 33, the scale adhering to the filter screen 33 will be shaken apart, thereby reducing the volume of scale and further preventing the inlet from becoming blocked.

[0043] Working principle: When the electric vehicle is in use, the drive motor 5 is turned on. The output shaft of the drive motor 5 will drive the turntable 7 to rotate. The rotating turntable 7 will drive the horizontal bar 9 to reciprocate within the water inlet chamber 1 through the hinge rod 8. During the movement of the horizontal bar 9, the vertical bar 10 and the first connecting rod 11 will also reciprocate within the water inlet chamber 1. At this time, the first cleaning wipe 12 set on the outer wall of the first connecting rod 11 will clean the inner wall of the water inlet chamber 1, removing any scale that may be attached to the inner wall of the water inlet chamber 1. This prevents scale from settling and condensing into large pieces on the inner wall of the water inlet chamber 1 due to prolonged uncleanliness, thus avoiding blockage of the cooler's outlet or inlet by large pieces of scale.

[0044] During the movement of the first connecting rod 11 with rack 13, the rack 13 on its outer wall drives the central gear 14 to rotate through the gear rotation. Since the first connecting rod 11 reciprocates under the action of the crossbar 9, it drives the central gear 14 to rotate in both directions, thereby driving the threaded rod 15 on its outer wall to rotate in both directions. During the rotation of the reciprocating threaded rod 15, it drives the first connecting plate 16 to move up and down through the threaded transmission, causing the second connecting rod 17 at the bottom of the first connecting plate 16 to move up and down inside the connecting tube 6. At this time, the outer wall of the second connecting rod 17 is fixed. The first cleaning wipe 12 can clean the inner wall of the connecting pipe 6, preventing scale from adhering to the inner wall of the connecting pipe 6 after the coolant is repeatedly heated and cooled through the aluminum connecting pipe 6. This reduces scale formation and avoids long-term scale buildup that could clog the outlet or inlet of the cooler, thus affecting the coolant circulation rate. Furthermore, since the first cleaning wipe 12 is connected to the second connecting rod 17 via a spring rod, the first cleaning wipe 12 will fit tightly against the inner wall of the connecting pipe 6 under the action of the spring force inside the spring rod, thereby improving the cleaning effect of the first cleaning wipe 12.

[0045] During the reciprocating motion of the second connecting rod 17, when the second connecting rod 17 moves upward, it will drive the connecting block 21 to move into the connecting tube 6. As the connecting block 21 moves, the side wall of the connecting tube 6 will contact the outer surface of the push rod 22, and as the connecting block 21 continues to move, it will press the push rod 22 towards the connecting block 21. At this time, the push rod 22 will drive the second connecting plate 23 at its bottom to move towards the outlet tube side and stretch the first spring 26. When the second connecting rod 17 moves downward, it will drive the connecting block 21 to move downward and gradually separate from the connecting tube 6. During the movement of the connecting block 21, the connecting tube 6... As the sidewall gradually stops pressing on the push rod 22, the push rod 22 will move away from the outlet pipe 4 under the elastic restoring force of the first spring 26. Through the up-and-down reciprocating motion of the second connecting rod 17, the second connecting plate 23 will reciprocate within the outlet chamber 2, thereby causing the connecting frame 27 and the third cleaning wipe 28 connected to the outside of the second connecting plate 23 to reciprocate within the outlet chamber 2, thus cleaning the inner wall of the outlet chamber 2. This prevents scale from accumulating and condensing on the inner wall of the inlet chamber 1 due to prolonged uncleanliness, and avoids the situation where scale accumulates more and more during subsequent use, causing blockage of the outlet.

[0046] Furthermore, during the rotation of the turntable 7, the pressing rod 32 on its top will rotate synchronously. During the rotation, the pressing rod 32 will contact the outer surface of the protrusion 31. As the turntable 7 continues to rotate, the pressing rod 32 will press the protrusion 31 and drive the L-shaped hook 29 to rotate. The end of the L-shaped hook 29 will separate from the filter screen 33 and compress the second spring 30. When the pressing rod 32 rotates to the point of disengaging from the protrusion 31, the L-shaped hook 29 will reset under the action of the elastic restoring force of the second spring 30 and impact the filter screen 33 to prevent scale from adhering to the filter screen 33 and causing the inlet to become blocked. When the L-shaped hook 29 impacts the filter screen 33, the scale adhering to the filter screen 33 will be shaken apart, thereby reducing the volume of scale and further preventing the inlet from becoming blocked.
