DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] An evaporative condenser pipe connection mechanism, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, it includes a vertical pipe 1, and flanges 2 are provided at both ends of the vertical pipe 1. The flanges 2 are used to connect the vertical pipe 1 with the water supply pipe 3. A rotating ring 4 is provided for rotation inside the vertical pipe 1. The rotating ring 4 and the vertical pipe 1 are rotatably connected 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 mobile ring 5 is provided for airtight sliding inside the vertical pipe 1. The vertical pipe 1, flange 2, water supply pipe 3, rotating ring 4, mobile ring 5 and sealed bearing are coaxially arranged. The outer periphery of the mobile ring 5 is in airtight sliding contact with the inner periphery of the vertical pipe 1. The mobile ring 5 and the vertical pipe 1 are connected through a first spring telescopic rod 6. The movable end of the first spring telescopic rod 6 is fixedly connected to the mobile ring 5, and the fixed end is fixedly connected to the vertical pipe 1. The rotating ring 4 and the mobile ring 5 are connected 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 retracted, and the first spring telescopic rod 6 is stretched to store energy. When using this device, connect the vertical pipe 1 to the water supply pipe 3, and the upper and lower ends of the vertical pipe 1 are connected to the water supply pipe 3 through the flange 2. Since the waterproof cloth tube 7 is twisted and retracted in the initial state, when water supply starts, the water pressure acts on the retracted part of the waterproof cloth tube 7, buffering the water pressure impact and weakening the water hammer effect. Under the continuous pressure of the water pressure, the retracted part of the waterproof cloth tube 7 gradually twists and unfolds, and 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 is shortened under the action of its own elastic tension, and the moving ring 5 drives the upper end of the waterproof cloth tube 7 upward Move, reduce the stacking of the waterproof cloth tube 7, and keep the interior of the waterproof cloth tube 7 unobstructed; the folds on the unfolded waterproof cloth tube 7 form a pleated flow channel, and its flexible surface can absorb impurities and calcium and magnesium ions in the water, effectively intercept scale, and reduce the risk of downstream pipeline blockage; the waterproof cloth tube 7 forms an air layer in the vertical pipe 1, which reduces the heat exchange between the vertical pipe 1 and the external environment; when the water supply is stopped, the waterproof cloth tube 7 is automatically twisted, retracted and reset under the action of the elastic reset mechanism. During the process of retracting and unfolding the waterproof cloth tube 7, the scale adhered to the inner wall of the waterproof cloth tube 7 falls off, thereby realizing automatic cleaning of the waterproof cloth tube 7.

[0022] Specifically, if Figure 1 and Figure 5As shown, the elastic reset mechanism described in this embodiment includes a sleeve 20, which is movably sleeved on the outside of the waterproof cloth tube 7, and 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 groove 21 is provided on the outer periphery of the sleeve 20, and a slide rod 22 is provided slidingly in the spiral groove 21. The slide rod 22 can slide along the spiral groove 21, and the slide rod 22 is connected to the vertical pipe 1 through a second spring telescopic rod 23. The movable end of the second spring telescopic rod 23 is fixedly connected to the slide rod 22, and the fixed end is installed on the vertical pipe 1. When the waterproof cloth tube 7 is twisted and unfolded 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 slide rod 22 slides along the spiral slide groove 21, and the slide 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 to store energy; when the water supply is stopped and the force of the water flow on the waterproof cloth tube 7 disappears, under the elastic tension of the second spring telescopic rod 23, the slide rod 22 moves upward, and the slide rod 22 slides along the spiral slide groove 21, causing the sleeve 20 and the rotating ring 4 to rotate in the opposite direction, thereby restoring the waterproof cloth tube 7 to the twisted and retracted state again.

[0023] Specifically, such as Figure 1 and Figure 5 As shown, the top side of the sleeve 20 of this embodiment abuts and contacts the bottom side of the movable ring 5. In the initial state, the top side of the sleeve 20 abuts and contacts the bottom side of the movable ring 5, and the waterproof cloth tube 7 is completely located within the sleeve 20. The sleeve 20 no longer rotates, the second spring telescopic rod 23 cannot be further shortened, and the first spring telescopic rod 6 cannot be further extended, thus preventing the waterproof cloth tube 7 from excessive twisting.

[0024] Further, such as Figure 1 、 Figure 2 and Figure 5As shown, the inner wall of the vertical tube 1 described in this embodiment is provided with a strip-shaped slide groove 40, and a screw rod 41 is rotatably installed in the strip-shaped slide groove 40. A slider 42 is slidably provided in the strip-shaped slide groove 40, and a threaded hole is provided on the slider 42 for threaded cooperation with the screw rod 41. The slider 42 is fixedly connected to the fixed end of the second spring telescopic rod 23, and a driving mechanism for driving the screw rod 41 to rotate is provided on the vertical tube 1. The screw rod 41 is driven by the driving mechanism to rotate forward or reverse, and the slider 42 slides up and down in the strip slide 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 slide rod 22 to slide along the spiral slide 21, the sleeve 20 and the rotating ring 4 rotate forward, and the waterproof cloth tube 7 is gradually twisted and expanded, and the expansion degree is adjusted until it is fully expanded; conversely, when the slider 42 moves upward, the waterproof cloth tube 7 is gradually twisted and closed, and the closing degree is increased; the closing and expansion of the waterproof cloth tube 7, as well as the closing degree and the expansion degree are controlled by the driving mechanism to meet different usage requirements; at the same time, during the process of folding and expanding the waterproof cloth tube 7, the scale adhered to the inner wall of the waterproof cloth tube 7 is fallen off, so that the waterproof cloth tube 7 is cleaned.

[0025] Furthermore, Figure 1 、 Figure 2 and Figure 5 As shown, the vertical tube 1 of this embodiment has a reserved hole 50 connected to the strip-shaped slide 40. A drive shaft 51 is rotatably installed in the reserved hole 50. The reserved hole 50 and the drive shaft 51 are rotatably connected via a sealed bearing. The inner ring of the sealed bearing is fixedly connected to the drive shaft 51, and the outer ring is fixedly connected to the reserved hole 50. A coaxial bevel gear 52 is fixedly mounted on the drive shaft 51. A coaxial bevel gear ring 53 is fixedly mounted on the screw rod 41. The bevel gear 52 meshes with the bevel gear ring 53. A handwheel 54 is fixedly mounted on the outer end of the drive shaft 51. By holding the handwheel 54, the user can rotate the drive shaft 51, and the drive shaft 51 drives the bevel gear ring 53 and the screw rod 41 to rotate through the bevel gear 52.

[0026] Furthermore, Figure 1 、 Figure 3 and Figure 5As shown, a slip ring 60 is fixedly provided in the vertical tube 1 described in this embodiment, and an insert rod 61 is slidingly provided in the slip ring 60. The insert rod 61 can only slide up and down in the slip ring 60. Blocks 62 are provided on the upper and lower sides of the insert rod 61 to prevent the insert rod 61 from falling out of the slip ring 60. A buoyancy ball 63 is fixedly provided at the lower end of the insert rod 61, and a spline 64 is fixedly provided at the upper end of the insert rod 61. Circumferentially distributed slots 65 are provided on the bottom side of the rotating ring 4. The inclined surface of the slot 65 is in sliding contact with the inclined surface of the spline 64. When the spline 64 is located in 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 is not supplying water, the buoyancy ball 63 drives the insertion rod 61 to move downward relative to the slip ring 60 under the action of gravity, and the spline 64 is separated from the slot 65. At this time, the rotating ring 4 can rotate forward and backward; when the water supply pipe 3 at the lower end of the vertical pipe 1 is supplying water, the buoyancy ball 63 drives the insertion rod 61 to move upward relative to the slip ring 60 under the action of buoyancy, and the spline 64 is inserted into the slot 65. At this time, the rotating ring 4 can only rotate forward. When the rotating ring 4 rotates forward, the inclined surface of the slot 65 gives the inclined surface of the spline 64 a downward thrust, pushing the spline 64 out of the slot 65; the rotating ring 4 can only rotate forward, preventing the waterproof cloth tube 7 from twisting, 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 remain unfolded under the action of water pressure.

[0027] Furthermore, Figure 1 As shown, the inner and outer sides of the waterproof cloth tube 7 of this embodiment are respectively provided with thermoplastic polyurethane coatings. The thermoplastic polyurethane coating has good waterproof, wear-resistant and crease-resistant properties, a smooth and hydrophobic surface, low scale adhesion, and is easy to clean.

[0028] 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 it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
