Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a cooling tower shading device that prevents direct sunlight from hitting a cooling tower and prevents an abnormal rise in water temperature.

[0002]

[Prior art]

 A cooling tower consisting of a radiator configured to circulate cooling water inside and a fan that blows air to the radiator is usually installed outdoors and used. For this reason, when exposed to direct sunlight, the water temperature may rise significantly and the cooling capacity may decline. For this reason, there have been some cases where a cover for sunshades has been provided in the past, but if such a cover is provided, it will interfere with ventilation, which rather impairs heat dissipation and has made it difficult to take measures.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention aims to provide a light-shielding device for a cooling tower that can be opened and closed as needed to prevent the rise in water temperature of the cooling tower due to direct sunlight.

[0004]

[Means for Solving the Problems]

 To this end, the present invention comprises a radiator in which cooling water circulates, a fan that blows air toward the radiator, and a light-shielding device provided above the radiator with a ventilation interval. The device has a plurality of guide wires stretched in parallel between opposite sides of a horizontally arranged frame, and a pair of shading sheets made of gauze cloth, canvas, etc. are respectively supported by a plurality of core rods orthogonal to the guide wires. Then, it is movably suspended along the guide wire, and the opening / closing wire is wound around a pulley provided on the frame so as to be stretched in parallel with the guide wire. Each of the light-shielding sheets reaches the center of the frame at the same time by fixing the tip ends of the opening and closing wires to the oppositely moving portions of the opening and closing wires and pulling and circulating the opening and closing wires with a winch. Characterized by being configured to obtain angel.

[0005]

[Embodiment of device]

 Next, an embodiment of the present invention will be described with reference to the drawings. The cooling tower 1 of this embodiment is a device for flowing and cooling the glassy melt discharged from the waste melting furnace into a water tank for rapid cooling and crushing. It is installed in the treatment plant, 2 is a radiator inside which the cooling water is circulated, and 3 is a fan provided below the radiator to send air to the radiator 2. is there.

A light-shielding device 6 is provided above the radiator 2 so as to be supported by a column 4 and to have a ventilation gap 5 between the radiator 2 and the radiator 2. That is, the channel-shaped frames 9a and 9b are horizontally supported on the lower surface of the horizontal beam 7 horizontally supported on the support column 4 via the hanging member 8, and the H-shaped channel 9a, 9b is interposed between the frames 9a and 9b. An intermediate frame 11 made of steel is horizontally supported, and a plurality of guide wires 12 are stretched between the frames 9a and 11 and between the frames 9b and 11 at regular intervals. FIG. 3 is an enlarged view showing the mounting portion of these guide wires 12, 13 is an eyebolt which is inserted through the frame 9a and fixed by the nut 14, and 15 is also inserted through the intermediate frame 11 and fixed by the nut 16. A guide wire 12 is stretched between the eyebolts 13 and 15 with the eyebolts. Reference numeral 16 is a wire clip that fixes the end portion of the guide wire 12.

Reference numerals 20a and 20b denote light-shielding sheets made of black ginseng. The light-shielding sheets 20a and 20b hang both ends of the thick core rods 21 and 22 to support them, and the middle portion of the light-shielding sheets is thinned at regular intervals. The mandrel 21 is hung on the mandrel 23, and the mandrel 21 at one end is hung by a hanging metal fitting 25 fixed to the eyebolt 13 by a nut 24, and the mandrel 22 at the other end is hung on the guide wire 12 by a hanging ring 26. It is hung by a suspending metal 27 that is slidably supported along the guide wire 12 by being inserted, and each core rod 23 in the middle can be slid by inserting a suspension ring 28 into the guide wire 12 as well. It is hung by the hanging metal fitting 29 supported by. The details of the suspension fitting 29 are shown in FIG. In this way, the light shielding sheets 20a and 20b are suspended and supported along the guide wire 12 between the frame 9a and the intermediate frame 11 and between the frame 9b and the intermediate frame 11, respectively.

On the other hand, 30 is a pulley provided on the frame 9 b, 31 is a pulley provided on the supporting column 4, and the opening / closing wire 32 is wound around the pulleys 30 and 31 and the opening / closing wire 32 is attached. The opening / closing wire 32 is stretched above the guide wire 12 so as to be parallel to the guide wire 12 by passing through the through holes formed in the frame 9a and the intermediate frame 11. Further, the opening / closing wire 32 is wound around the drum of the ratchet type winch 34 via the pulley 33 provided on the column 4. As shown in FIG. 5, both ends of the opening / closing wire 32 are connected to a turnbuckle 35 by wire clips 36 to form the opening / closing wire 32 in a loop shape. Therefore, by rotating the handle 37 of the winch 34, the opening / closing wire 32 can be pulled in the desired direction as indicated by the arrow, and the opening / closing wire tensioned on the light shielding sheets 20a, 20b for the pulley 30 is opened and closed. The wires 32 move in opposite directions. Then, as shown in FIG. 5, the mandrel 22 at the tip of one light-shielding sheet 20a is fixed to a part of the opening / closing wire 32 via the lead slider 38, and the tip of the other light-shielding sheet 20b is fixed. The core rod 22 is fixed to a part of the opening / closing wire 32, which has a different fixing position from the lead slider 38 and moves in the opposite direction, via the lead slider 39.

For this reason, if the handle 37 is rotated in a predetermined direction and the opening / closing wire 32 is circulated in the direction shown by the arrow, it is fixed to the core rod 22 and the lead slider 39 fixed to the lead slider 38. The core rods 22 are moved toward the intermediate frame 11, respectively, so that the light shielding sheets 20a and 20b can be extended at the same time, and the radiator 2 can be prevented from being exposed to direct sunlight. Further, when the handle 37 is rotated in the opposite direction, the opening / closing wire 32 circulates in the opposite direction, so that the core rods 22 of both the light shielding sheets 20a and 20b move toward the frames 9a and 9b, respectively. 20b can be contracted and the upper part of the radiator 2 can be opened to improve ventilation. In this embodiment, an example in which the manual winch 34 is provided is shown, but it goes without saying that the opening / closing wire may be circulated by using an electric winch. As the material of the light-shielding sheets 20a and 20b, a gauze cloth is preferable in terms of breathability, but other canvas may be used.

[Effect of device]

 As described above, in the cooling tower shading device of the present invention, the shading sheet can be extended as necessary by operating the winch so that the radiator is not exposed to direct sunlight, so that an abnormal rise in water temperature can be prevented and At night or when it is cloudy, the cooling effect can be prevented from being impaired by shrinking the light-shielding sheet to improve the air flow and the awl. However, in the present invention, since a pair of light shielding sheets are symmetrically provided and the opening / closing wires are circulated so that the respective light shielding sheets are simultaneously expanded and contracted, the opening / closing operation can be performed easily in a short time. There is an advantage that can be done.
