DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The utility model provides a technical solution: an air conditioner using river water to assist cooling, according to Figure 1-3 and Figure 5 As shown, there is a trumpet-shaped water intake head in the water intake chamber 1, and the water intake head is connected to the water intake pump 2, the cyclone desander 3 and the mechanical filter 4 in sequence through pipelines for filtering.

[0026] In a further embodiment, the main process function of the cyclone desander 3 is to intercept solid particles with a diameter of ≧0.1mm in the raw water; the working principle is to intercept sand particles according to the screening principle of solid particles in the fluid when rotating in the desander. After the raw water flows into the equipment tangentially from the desander inlet with a certain pressure, a strong rotational motion is generated. Due to the different densities of sand and water, under the action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged from the water outlet, and the sand particles with high density are discharged from the sewage outlet at the bottom of the equipment, thereby achieving the purpose of sand removal; the main process function of the mechanical filter 4 is to further intercept solid impurities such as entanglements in the raw water after the cyclone desander 3; the working principle is that the mechanical filter 4 is mainly composed of a retaining pipe, a cylinder, a PP filter element with a knife edge, a flange, a flange cover and fasteners. When the fluid passes through the cylinder and enters the filter element, the solid impurities are cut and blocked in the filter element, while the clean fluid is filtered through the filter element and discharged from the filter outlet. When slag discharge is required, the drain valve at the bottom of the cylinder is opened to discharge the water-containing solid impurities; the filtered river water enters the heat exchanger 8 and the cooling water in the central air-conditioning cooling water circulation pipeline for heat exchange.

[0027] Specifically, the water inlet side of the water intake chamber 1 is detachably connected to the filter mechanism 6 through a symmetrically arranged movable sleeve 5 .

[0028] In a further embodiment, the filter mechanism 6 includes a mounting frame 601 , and a filter 602 is disposed inside the mounting frame 601 .

[0029] Specifically, the movable sleeve 5 includes a turning handle 501, and one end of the turning handle 501 is connected to the first bevel gear 502 through a driving rod, the first bevel gear 502 is inside the movable groove opened in the water intake chamber 1, and the first bevel gear 502 is meshed with the second bevel gear 503, the inner side of the second bevel gear 503 is connected to the second threaded rod 504, and the outer side of the second threaded rod 504 is connected to the threaded sleeve 505, and a sleeve groove matching the threaded sleeve 505 is opened on the mounting frame 601.

[0030] In a further embodiment, the tumbler 501 includes a tumbler body, a fixing ring is provided on the outside of the tumbler body, and a plurality of groups of sockets are provided on the fixing ring, a limiting hole used in conjunction with the sockets is provided on the water intake chamber 1, and the sockets and the limiting holes are detachably connected via a U-shaped limiting rod, so that the position of the tumbler 501 is limited to a certain extent by the U-shaped limiting rod to prevent the tumbler 501 from rotating on its own.

[0031] In a further embodiment, a limiting plate 5051 slidably connected to the threaded sleeve 505 is disposed inside the movable groove.

[0032] When the filter mechanism 6 needs to be removed and replaced, the handle 501 is rotated, and the handle 501 drives the first bevel gear 502 to rotate through the driving rod. The first bevel gear 502 is meshed with the second bevel gear 503, thereby driving the second bevel gear 503 and the second threaded rod 504 to rotate. Under the action of the rotation of the second threaded rod 504, the threaded sleeve 505 moves.

[0036] In yet a further embodiment, the protection box 702 is installed on the inner top of the water intake chamber 1 .

[0037] In yet a further embodiment, the moving rod 707 is slidably connected to the inside of the water intake chamber 1 .

[0038] When the filter mechanism 6 is clogged, the waterproof motor 701 is turned on, and the double-groove driving wheel 703 rotates under the action of the waterproof motor 701, thereby driving the driven wheels 705 and the first threaded rod 706 set on both sides to rotate through the transmission belt 704, and the moving rod 707 moves under the action of the rotation of the first threaded rod 706, thereby driving the long rod cleaning brush 708 to move synchronously, and the blockage on the filter 602 can be brushed off under the action of the movement of the long rod cleaning brush 708.
