Description

Technical Field

[0001] The utility model relates to the field of tools for power plant cooling towers, and specifically to an ice removal tool for cooling towers. Background Art

[0002] At present, icing occurs in the cooling water towers of power plant circulating water plants in winter. This is mainly because the environmental temperature is too low, resulting in too low water temperature in the tower, and the dripping water condenses to form ice. If not dealt with in time, it will cause damage to the tower body and affect the normal operation of the circulating water system. The commonly used existing ice removal shovels are usually in the structure of a shovel body or a cone, with low ice removal efficiency and unable to effectively remove the hanging ice. The most important thing is that the fallen ice cubes will fall into the cooling water tower pool, blocking the suction inlet of the circulating water pump, resulting in low flow rate and cavitation damage of the circulating water pump, and even leading to the occurrence of non-stop accidents in the power plant circulating water. In view of this, an ice removal tool for cooling towers is proposed. Summary of the Invention

Detailed Embodiments

[0018] The following further describes the above solutions with specific embodiments. It should be understood that these embodiments are used to illustrate the present invention rather than limit the scope of the present invention. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0019] In a specific embodiment, a cooling tower deicing tool is provided, comprising a vehicle body 1, wherein the bottom of the vehicle body 1 in this example is provided with a double set of rollers, and a trolley handle 1.3 is provided at the rear end of the vehicle body, so that the trolley can be pushed for displacement. In order to collect hanging ice, a collection refrigerator 1.1 is provided at the bottom thereof.

[0020] Similarly, in order to collect ice at the bottom of the hanging ice, a bucket frame 2 is provided at the front end of the vehicle body 1, and an ice collecting bucket 3 is installed at the front end of the bucket frame 2. The ice collecting bucket 3 can be extended to the front end of the vehicle body through the bucket frame 2, and can reach the bottom of the hanging ice to receive the hanging ice. In this example, in order to adjust the position of the bucket frame 2, the rear end of the bucket frame 2 is hinged on the vehicle body 1. In addition, a winch 5 is provided on the vehicle body 1. Similar to the prior art, a steel wire rope is wound around the drum of the winch 5, and the end of the steel wire rope is connected to the front end of the bucket frame 2. Therefore, the rotation of the winch 5 can pull the bucket frame 2 to swing, and then the position of the ice collecting bucket 3 can be adjusted, and combined with the movement of the vehicle body 1, the ice collecting bucket 3 can be easily adjusted to align with the hanging ice, ensuring that the ice collecting bucket 3 can accurately receive the fallen hanging ice. In this example, the outer contour of the cooling tower is a circle, and the opening of the ice collecting bucket 3 has a contour that fits the outer contour of the cooling tower in order to better receive the ice. In order to prevent the vehicle body from being unbalanced due to the excessive weight of ice in the ice collecting bucket 3, a counterweight box 14 is detachably mounted on the handle 1.3 of the trolley, and gravel or water can be placed in the counterweight box 14 to achieve the balance of the front and rear of the vehicle body and prevent the vehicle body from tipping forward, thereby improving the stability during operation.

[0021] In this example, in order to process the ice in the ice collecting bucket 3, an ice guide trough 2.1 is provided on the top of the bucket frame 2, one end of which is connected to the ice collecting bucket 3 and the other end is connected to the ice collecting refrigerator 1.1, and the hanging ice can slide to the ice collecting refrigerator 1.1 through the ice guide trough 2.1. In addition, when in use, the bucket frame 2 is pulled to move in the vertical direction by the winch 5, so that the ice in the ice collecting bucket 3 quickly slides into the ice collecting bucket. Since the bucket frame 2 is hinged to the front end of the vehicle body 1, a connection discontinuity is generated, and the setting angle of the two will change with the swing of the bucket frame 2, which will cause the ice to get stuck at the discontinuity. In addition, in order to prevent melt water from flowing out of the gap between the bucket frame 2 and the vehicle body 1, causing secondary icing on the workbench, a flexible trough plate 4 is laid on the ice guide trough 2.1, and the end of the flexible trough plate 4 extends into the ice collecting refrigerator 1.1, so that the melt water and hanging ice can completely enter the ice collecting refrigerator 1.1 through the flexible trough plate 4.

[0022] In addition, to facilitate the discharge of the ice hanging on the ice collection box 1.1 and increase the ice storage capacity during use, a defrosting heating plate 13 is laid at the bottom of the ice collection box 1.1. The defrosting heating plate 13 adopts a traditional waterproof heating mechanism and is powered by a storage battery 11. Its switch is controlled by a control console 12. Thus, a part of the ice hanging in the ice collection box 1.1 can be melted by the heating plate. At this time, the melted water can be seen being discharged and directly drained into the cooling tower water tank, improving the accommodation capacity of the ice collection box 1.1, avoiding frequent ice collection box cleaning operations, improving efficiency, and reducing labor intensity.

[0023] On this basis, to achieve the detachment of the hanging ice, this example further includes a heating coil support rod 6 and a heating coil 10 installed at its front end. An operating handle 6.1 is provided at the rear end of the heating coil support rod 6. In addition, a slide rail 9 is provided on the top of the vehicle body 1. A sliding frame 8 is slidably installed on the top of the slide rail 9 and can move in the front-rear direction of the vehicle body 1. A ball joint 7 is installed on the top of the sliding frame 8. Specifically, a spherical plain bearing can be used for the ball joint 7. The heating coil support rod 6 is installed on the ball joint 7, making its front and rear ends form a lever structure. During the ice removal operation, first move the vehicle body to the surrounding of the cooling tower water tank. At this time, the vehicle body can be temporarily fixed to the surrounding fence of the water tank for preliminary adjustment operations. Then, the operator holds the handle 6.1 and can easily adjust the position of the heating coil 10 by moving the sliding frame 8 back and forth and the swinging of the heating coil support rod 6 on the ball joint 7. At the same time, the position of the vehicle is adjusted so that the inside or outer wall of the heating coil 10 abuts against the outside of the hanging ice. The ice column is cut through the heating coil 10, and the hanging ice is cut and removed by means of heating and melting the ice, and the root of the hanging ice is cut off, causing the entire hanging ice column to fall off, improving the ice removal efficiency. At this time, the ice collection hopper 3 can be adjusted to be located at the bottom of the cut hanging ice for receiving and collecting the cut hanging ice. Therefore, it is possible to avoid the drawback that the hanging ice falls into the cooling tower water tank during ice removal, resulting in the blockage of the circulating water pump, and ensuring the stability of the system operation.

[0024] In addition, to adjust the length of the heating coil support rod 6 and thus adjust the position of the heating coil 10 within a larger range, a threaded sleeve 6.2 is provided on the heating coil support rod 6. The heating coil support rod 6 is divided into two sections, and threads are provided at the separated ends. The two ends of the threaded sleeve 6.2 are respectively screwed onto the separated ends of the two sections. It should be noted that the threads at both ends have opposite helix directions. Thus, by screwing the threaded sleeve 6.2, the length of the heating coil support rod 6 can be adjusted. Further, for convenience of adjustment, the threaded sleeve 6.2 is provided at a position close to the ball joint 7.

[0025] In this example, to supply power and control the winch 5 and the heating coil 10, a storage battery 11 and a control console 12 are further included. Through the control console 12, the storage battery 11 can supply power to the winch 5 and the heating coil 10. Among them, the control console 12 is a prior art and is provided with corresponding control switches.

The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
