Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and specifically to a cooling tower windbreak device. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. In cold winters, to prevent the water inside the cooling tower from freezing due to cold air, a windproof and cold-proof device is needed at the air inlet. For example, patent publication CN213688044U, "A Vertical Windproof Device for a Cooling Tower," provides a device that uses a baffle cloth for wind protection. However, the baffle cloth is relatively soft and easily deformed by wind, causing air leakage and resulting in poor windproofing. Summary of the Invention

[0003] This invention addresses the problems of cooling towers freezing due to cold winds during winter use and the poor effectiveness of existing windbreak devices. It provides a cooling tower windbreak device that improves the windbreak effect and prevents the water inside the cooling tower from freezing.

[0004] To solve the above problems, the technical solution of this utility model is:

[0005] A cooling tower windbreak device includes a support cylinder, a connecting rod, a windbreak cloth, and a top pressing component. A rotating rod is rotatably mounted inside the support cylinder. Crossbars are connected to the upper and lower parts of the right side of the outer wall of the support cylinder. Slide grooves are provided on the opposite surfaces of the two crossbars, penetrating the left end of each crossbar. The two ends of the connecting rod are located within the right ends of the two slide grooves, and are detachably connected to the crossbars on the same side. The right end of the windbreak cloth is connected to the connecting rod, and the left end movably penetrates the peripheral wall of the support cylinder and connects to the rotating rod. The two slide grooves cover the upper and lower ends of the windbreak cloth. The upper and lower ends of the windbreak cloth are both pressed and limited by the top pressing component on the crossbars on the same side. The upper top pressing component includes a housing. The rear opening of the housing is fixedly connected to the front side of the crossbar. A top plate, which slidably extends into the slide groove from the rear end of the housing, is movably mounted inside the housing and penetrates the crossbar. The rear end of the top plate presses against the upper end of the windbreak cloth in the slide groove. The top plate is driven forward or backward by a screw.

[0006] Furthermore, the upper end of the rotating rod penetrates the upper side plate of the bearing cylinder, and the upper end of the rotating rod is connected to a rotating plate. The upper part of the rotating rod is rotatably connected to the upper side plate of the bearing cylinder.

[0007] Furthermore, the outer top surface of the bearing cylinder is provided with friction texture, and the rotating plate is threadedly connected to the screw rod. The lower end of the screw rod contacts the friction texture, and the upper end is connected to the rotating plate.

[0008] Furthermore, the upper end of the windproof cloth is flush with the upper end of the connecting rod, and the lower end is flush with the lower end of the connecting rod. The portion of the windproof cloth located inside the bearing cylinder is wrapped around the outside of the rotating rod, and the left end of the windproof cloth is fixedly connected to the peripheral wall of the rotating rod.

[0009] Furthermore, the connecting rod is located on the right side of the end of each of the two slide grooves and is connected to a screw rod three with the end facing to the right. The end of each screw rod three moves through the crossbar on the right side of the slide groove and is limited by a nut.

[0010] Furthermore, the screw is threadedly connected to the front side plate of the housing, the rear end of the screw is rotatably connected to the front side of the top plate on the top pressure member, and the front end is connected to the rotating plate three.

[0011] Furthermore, multiple connecting plates are spaced apart between the rear portions of the opposing surfaces of the two crossbars. All connecting plates are located on the rear side of the slide groove, and the front side of each connecting plate is flush with the rear side of the slide groove.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] The two top pressing members of this utility model limit the upper and lower ends of the unfolded windproof cloth, the connecting rod limits the right end of the windproof cloth, and the rotating rod limits the left end of the windproof cloth. The windproof cloth is arranged in front of the air inlet of the cooling tower. When it is impacted by wind, it can prevent the windproof cloth from deforming, prevent air leakage, and improve the windproof effect.

[0014] The multiple connecting plates of this invention can support the windbreak cloth and also prevent the windbreak cloth from deforming.

[0015] This invention allows the windproof cloth to be stored in the bearing cylinder by rotating the rotating rod after the limiting position on the end of the windproof cloth is released, making storage convenient; it also facilitates air intake at the air inlet of the cooling tower when the temperature rises.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1-6 As shown, a cooling tower windbreak device includes a support cylinder 1, a connecting rod 2, a windbreak cloth 3, and a top pressure component. The support cylinder 1 is a cylindrical body with its lower opening sealed by a bottom plate. A rotating rod 4, which is a cylindrical rod, is rotatably installed inside the support cylinder 1. A crossbar 5, which is a rectangular rod, is connected to the upper and lower parts of the right side of the outer wall of the support cylinder 1. Sliding grooves 6, both rectangular grooves, are provided on the opposite surfaces of the two crossbars 5, with their openings facing each other and passing through the left end of the crossbar 5. The connecting rod 2, which is a rectangular rod, has its two ends located within the right ends of the two sliding grooves 6. Both ends of the connecting rod 2 are in sliding contact with the corresponding sliding groove 6, and are detachably connected to the crossbar 5 on the same side. The windbreak cloth 3 is connected to the connecting rod 2 at its right end and detachably connected to the crossbar 5 at its left end. A rotating rod 4 is connected to the circumferential wall of the bearing cylinder 1. The bearing cylinder 1 has a through hole 7 for the windproof cloth 3 to pass through. Two sliding grooves 6 cover the upper and lower ends of the windproof cloth 3 respectively. The upper and lower ends of the windproof cloth 3 are pressed and limited by the pressing member on the crossbar 5 on the same side. The upper pressing member includes a housing 8. The housing 8 is a hollow cuboid with an open rear end. The open rear end of the housing 8 is fixedly connected to the front side of the crossbar 5. A top plate 9 is slidably provided in the housing 8, with its rear end moving through the crossbar 5 and extending into the sliding groove 6. The crossbar 5 has a through hole 10 for the top plate 9 to pass through. The rear end of the top plate 9 presses against the upper end of the windproof cloth 3 in the sliding groove 6. The upper end of the windproof cloth 3 is pressed between the rear end of the top plate 9 and the rear side of the sliding groove 6. The top plate 9 is driven to move forward or backward by a screw 11.

[0025] The upper end of the rotating rod 4 passes through the upper side plate of the bearing cylinder 1, and the upper end of the rotating rod 4 is connected to the rotating plate 12. The upper part of the rotating rod 4 is rotatably connected to the upper side plate of the bearing cylinder 1 via the bearing 20.

[0026] The outer top surface of the bearing cylinder 1 is provided with friction texture 13, and the rotating plate 12 is threadedly connected to the screw 2 14. The lower end of the screw 2 14 contacts the friction texture 13, and the upper end is connected to the rotating plate 2 15.

[0027] The upper end of the windproof cloth 3 is flush with the upper end of the connecting rod 2, and the lower end is flush with the lower end of the connecting rod 2. The part of the windproof cloth 3 located inside the bearing cylinder 1 is wrapped around the rotating rod 4, and the left end of the windproof cloth 3 is fixedly connected to the periphery of the rotating rod 4.

[0028] The connecting rod 2 is located on the right side of the end of the two slide grooves 6, and is connected to a screw 3 16 with the end facing to the right. The end of each screw 3 16 moves through the crossbar 5 on the right side of the slide groove 6 and is limited by the nut 17.

[0029] The screw 11 is threaded to the front side plate of the housing 8. The rear end of the screw 11 is rotatably connected to the front side of the top plate on the top pressing component, and the front end is connected to the rotating plate 3 18. The top plate 9 is a rectangular plate.

[0030] Multiple connecting plates 19 are spaced apart between the rear of the opposite surfaces of the two crossbars 5. The multiple connecting plates 19 are all located on the rear side of the slide groove 6. The front side of each connecting plate 19 is flush with the rear side of the slide groove 6. The multiple connecting plates 19 are spaced apart along the length of the crossbars 5. The connecting plates 19 are rectangular plates.

[0031] In use, this utility model is placed in front of the air inlet of the cooling tower, with the front side of the windbreak cloth 3 facing the wind. When the wind blows towards the windbreak cloth 3, the upper end of the windbreak cloth 3 is located in the groove 6 of the upper crossbar 5, and the upper end of the windbreak cloth 3 is pressed between the rear end of the upper top plate 9 and the rear side of the groove 6, preventing the upper end of the windbreak cloth 3 from moving. The lower end of the windbreak cloth 3 is located in the groove 6 of the lower crossbar 5, and the lower end of the windbreak cloth 3 is pressed between the rear end of the lower top plate 9 and the rear side of the groove 6, preventing the lower end of the windbreak cloth 3 from moving. The connecting rod 2 is connected to two crossbars 5 at both ends. The connecting rod 2 does not move. The right end of the windproof cloth 3 does not move because it is connected to the connecting rod 2. The lower end of the screw 14 presses against the friction texture 13, limiting the rotation of the limiting plate 12. The rotating rod 4 does not rotate. Therefore, the left end of the windproof cloth 3 will not move. Thus, the windproof cloth 3 of this utility model can avoid deformation when it is impacted by wind. Moreover, the multiple connecting plates 19 can support the windproof cloth 3, which can also prevent the windproof cloth 3 from deforming.

[0032] When the temperature rises and the windbreak of this utility model is no longer needed, unscrew the nuts 17 on the two screws 16 to disconnect the connecting rod 2 and the two crossbars 5. Rotate the screws 11 on the two top pressure members so that the screws 11 drive the connected top plate 9 away from the windbreak cloth 3 and so that the rear end of the top plate 9 is located in the housing 8 of the top pressure member, without affecting the movement of the connecting rod 2. The upper and lower ends of the windbreak cloth 3 are no longer restricted. Rotate the screw 14 so that the lower end of the screw 14 no longer presses against the friction texture 13. The rotating rod 4 is no longer restricted. Rotate the rotating rod 4. When the rotating rod rotates, the windbreak cloth 3 enters the bearing cylinder 1 and is wound around the rotating rod 4. At the same time, the right end of the windbreak cloth 3 pulls the connecting rod 2 to the left. The two ends of the connecting rod 2 move along the corresponding slide groove 6 until the connecting rod 2 contacts the bearing cylinder 1. At this time, the windbreak cloth 3 between the two crossbars 5 is stored and no longer blocks the air inlet of the cooling tower.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
