Detailed implementation mode

[0015] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] An evaporation condenser pipe connection mechanism, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, it includes a vertical pipe 1. Flanges 2 are provided at both ends of the vertical pipe 1. The flanges 2 are used to connect the vertical pipe 1 to the water supply pipe 3. A rotating ring 4 is rotatably arranged inside the vertical pipe 1. The rotating ring 4 is rotatably connected to the vertical pipe 1 through a sealed bearing. The inner ring of the sealed bearing is fixedly connected to the rotating ring 4, and the outer ring is fixedly connected to the vertical pipe 1. A moving ring 5 is hermetically slidably arranged inside the vertical pipe 1. The vertical pipe 1, the flanges 2, the water supply pipe 3, the rotating ring 4, the moving ring 5 and the sealed bearing are coaxially arranged. The outer circumference of the moving ring 5 is in hermetically slidable contact fit with the inner circumference of the vertical pipe 1. The moving ring 5 is connected to the vertical pipe 1 through a first spring telescopic rod 6. The movable end of the first spring telescopic rod 6 is fixedly connected to the moving ring 5, and the fixed end is fixedly connected to the vertical pipe 1. The rotating ring 4 is connected to the moving ring 5 through a waterproof cloth tube 7. An elastic reset mechanism is provided between the rotating ring 4 and the vertical pipe 1. In the initial state, the waterproof cloth tube 7 is twisted and folded, and the first spring telescopic rod 6 is stretched and energy is stored. When using this device, the vertical pipe 1 is connected to the water supply pipe 3. The upper and lower ends of the vertical pipe 1 are connected to the water supply pipe 3 through the flanges 2. Since the waterproof cloth tube 7 is twisted and folded in the initial state, when the water supply starts, the water pressure acts on the folded part of the waterproof cloth tube 7 to buffer the water pressure impact and weaken the water hammer effect. Under the continuous pressure of the water pressure, the folded part of the waterproof cloth tube 7 gradually twists and unfolds. The lower end of the waterproof cloth tube 7 drives the rotating ring 4 to rotate, and the elastic reset mechanism stores energy. At the same time, the first spring telescopic rod 6 shortens under the action of its own elastic tension, and the moving ring 5 drives the upper end of the waterproof cloth tube 7 to move upward, reducing the stacking of the waterproof cloth tube 7 and keeping the inside of the waterproof cloth tube 7 unobstructed; the folds on the unfolded waterproof cloth tube 7 form a corrugated flow channel, and its flexible surface can adsorb impurities and calcium and magnesium ions in the water, effectively intercepting scale and reducing the risk of blockage of the downstream pipeline; the waterproof cloth tube 7 forms an air layer inside the vertical pipe 1, reducing the heat exchange between the vertical pipe 1 and the external environment; when the water supply stops, the waterproof cloth tube 7 automatically twists and folds back under the action of the elastic reset mechanism. During the folding and unfolding process of the waterproof cloth tube 7, the scale adhered to the inner wall of the waterproof cloth tube 7 falls off, realizing the automatic cleaning of the waterproof cloth tube 7.

[0017] Specifically, as Figure 1 and Figure 5As shown, the elastic reset mechanism in this embodiment includes a sleeve 20. The sleeve 20 is movably sleeved outside the waterproof cloth tube 7. The sleeve 20 is fixedly connected to the rotating ring 4. The rotating ring 4 is coaxially arranged with the waterproof cloth tube 7 and the sleeve 20. A spiral chute 21 is formed on the outer periphery of the sleeve 20. A sliding rod 22 is slidably arranged in the spiral chute 21. The sliding rod 22 can slide along the spiral chute 21. The sliding rod 22 is connected to the vertical tube 1 through a second spring telescopic rod 23. The movable end of the second spring telescopic rod 23 is fixedly connected to the sliding rod 22, and the fixed end is installed on the vertical tube 1. When the waterproof cloth tube 7 twists and unfolds under the action of water pressure, the lower end of the waterproof cloth tube 7 drives the rotating ring 4 to rotate. The rotating ring 4 drives the sleeve 20 to rotate forward. The sliding rod 22 slides along the spiral chute 21. The sliding rod 22 drives the movable end of the second spring telescopic rod 23 to move downward, and the second spring telescopic rod 23 is stretched and stores energy. When the water supply stops and the acting force of the water flow on the waterproof cloth tube 7 disappears, under the elastic pulling force of the second spring telescopic rod 23, the sliding rod 22 moves upward. The sliding rod 22 slides along the spiral chute 21, causing the sleeve 20 and the rotating ring 4 to rotate in the reverse direction, and then the waterproof cloth tube 7 returns to the twisted and retracted state again.

[0018] Specifically, as Figure 1 and Figure 5 shown, the top side of the sleeve 20 in this embodiment abuts against and contacts the bottom side of the moving ring 5 in a mating manner. In the initial state, the top side of the sleeve 20 abuts against and contacts the bottom side of the moving ring 5. The waterproof cloth tube 7 is completely located inside the sleeve 20. The sleeve 20 no longer continues to rotate. The second spring telescopic rod 23 cannot continue to shorten, and the first spring telescopic rod 6 cannot continue to stretch, avoiding excessive twisting of the waterproof cloth tube 7.

[0019] Furthermore, as Figure 1 、 Figure 2 and Figure 5As shown in the figure, a strip-shaped chute 40 is formed in the inner wall of the vertical pipe 1 of this embodiment. A lead screw 41 is rotatably installed in the strip-shaped chute 40. A slider 42 is slidably arranged in the strip-shaped chute 40. A threaded hole that is in threaded fit with the lead screw 41 is formed in the slider 42. The slider 42 is fixedly connected to the fixed end of the second spring telescopic rod 23. A driving mechanism for driving the lead screw 41 to rotate is provided on the vertical pipe 1. By driving the lead screw 41 to rotate forward or backward through the driving mechanism, the slider 42 slides up and down in the strip-shaped chute 40, and the slider 42 drives the fixed end of the second spring telescopic rod 23 to move up and down. When the slider 42 moves downward, it drives the second spring telescopic rod 23 and the sliding rod 22 to slide along the spiral chute 21, and the sleeve 20 and the rotating ring 4 rotate forward, and the waterproof cloth tube 7 gradually twists and unfolds, adjusting the unfolding degree until it is completely unfolded. On the contrary, when the slider 42 moves upward, the waterproof cloth tube 7 gradually twists and closes, increasing the closing degree. By controlling the driving mechanism, the waterproof cloth tube 7 is closed and unfolded, and the closing degree and the unfolding degree are controlled to meet different usage requirements. At the same time, during the process of the waterproof cloth tube 7 being folded and unfolded, the scale adhered to the inner wall of the waterproof cloth tube 7 falls off, realizing the cleaning of the waterproof cloth tube 7.

[0020] Furthermore, as Figure 1 , Figure 2 and Figure 5 shown, a reserved hole 50 communicating with the strip-shaped chute 40 is formed in the vertical pipe 1 of this embodiment. A driving shaft 51 is rotatably arranged in the reserved hole 50. The reserved hole 50 and the driving shaft 51 are rotatably connected through a sealing bearing. The inner ring of the sealing bearing is fixedly connected to the driving shaft 51, and the outer ring is fixedly connected to the reserved hole 50. A coaxial bevel gear 52 is fixedly installed on the driving shaft 51. A coaxial bevel gear ring 53 is fixedly arranged on the lead screw 41. The bevel gear 52 and the bevel gear ring 53 are meshed and matched. A handwheel 54 is fixedly arranged at the outer end of the driving shaft 51. By holding the handwheel 54, the user can rotate the driving shaft 51, and the driving shaft 51 drives the bevel gear ring 53 and the lead screw 41 to rotate through the bevel gear 52.

[0021] Furthermore, as Figure 1 , Figure 3 and Figure 5As shown in the figure, a slip ring 60 is fixedly arranged inside the vertical pipe 1. A plug rod 61 is slidably arranged inside the slip ring 60. The plug rod 61 can only slide up and down inside the slip ring 60. Block 62 for preventing the plug rod 61 from falling out of the slip ring 60 is arranged on both the upper and lower sides of the plug rod 61. A buoyancy ball 63 is fixedly arranged at the lower end of the plug rod 61, and a plug tooth 64 is fixedly arranged at the upper end of the plug rod 61. A circumferentially distributed slot 65 is formed on the bottom side of the rotating ring 4. The inclined surface of the slot 65 is in sliding contact and cooperation with the inclined surface of the plug tooth 64. When the plug tooth 64 is located inside the slot 65, the rotating ring 4 can only rotate in the forward direction. When the water supply pipe 3 at the lower end of the vertical pipe 1 does not supply water, the buoyancy ball 63 drives the plug rod 61 to move downward relative to the slip ring 60 under the action of gravity, and the plug tooth 64 is separated from the slot 65. At this time, the rotating ring 4 can rotate in the forward and reverse directions; when the water supply pipe 3 at the lower end of the vertical pipe 1 supplies water, the buoyancy ball 63 drives the plug rod 61 to move upward relative to the slip ring 60 under the action of buoyancy, and the plug tooth 64 is inserted into the slot 65. At this time, the rotating ring 4 can only rotate in the forward direction. When the rotating ring 4 rotates in the forward direction, the inclined surface of the slot 65 gives a downward thrust to the inclined surface of the plug tooth 64, pushing the plug tooth 64 out of the slot 65; the rotating ring 4 can only rotate in the forward direction, avoiding the waterproof cloth tube 7 from twisting and retracting and resetting under the action of the second spring telescopic rod 23, thereby reducing the resistance of the waterproof cloth tube 7 to the water flow, and the waterproof cloth tube 7 does not need to be kept unfolded under the action of water pressure.

[0022] Furthermore, as Figure 1 shown in the figure, thermoplastic polyurethane coatings are respectively arranged on the inner and outer sides of the waterproof cloth tube 7 in this embodiment. The thermoplastic polyurethane coating has good waterproof, wear-resistant, and crease-resistant properties, with a smooth and hydrophobic surface and low scale adhesion, which is convenient for scale cleaning.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
