Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower equipment, in particular to a water distribution tray cover plate. Background Art

[0002] As the scale of industrial production continues to expand, the demand for cooling tower equipment is also growing. Usually, a water distribution pan is set on the top of the cooling tower to achieve uniform water distribution. In actual production, some cooling towers are not equipped with a water distribution pan cover, and some cooling towers are equipped with a water distribution pan cover.

[0003] If the cooling tower is not equipped with a water distribution pan cover, the daily maintenance cost is often higher and the loss of circulating water is also higher. With the improvement of people's environmental awareness, more and more equipment requires the addition of water distribution pan covers. Commonly used water distribution pan covers are divided into two types: with handles and without handles. The water distribution pan cover without handles is very inconvenient to move due to its large size.

[0004] Traditional water distribution pan covers often use fixed-mounted handles, which are installed on the upper surface of the water distribution pan cover. The handle itself is N-shaped and fixed on the upper surface of the water distribution pan cover. It will protrude from the upper surface of the water distribution pan cover. The water distribution pan cover is at the top of the cooling tower. People are easily tripped when walking on it, posing a safety hazard. Utility Model Content

[0005] The utility model aims to provide a water distribution pan cover to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water distribution tray cover, comprising a cover body, a handle body, a limit bolt and a locking nut, the handle body is symmetrically provided with a first plug plate and a second plug plate on the side, the cover body is symmetrically provided with handle insertion holes that match the first plug plate and the second plug plate, the first plug plate and the second plug plate are respectively inserted into the handle insertion holes, and the first plug plate and the second plug plate are connected to the handle insertion holes by sliding, and the handle body is fitted with the upper surface of the cover body;

[0007] The handle body can be pulled upwards to make the first plug plate and the second plug plate of the handle body slide in the handle insertion hole, and the handle body can be lifted up. When not in use, the handle body will naturally fall down to fit with the cover body;

[0008] The first plug plate and the second plug plate have through-going limiting holes at their ends, the limiting bolts are inserted into the limiting holes, and the locking nuts are threadedly connected to the limiting bolts to limit the first plug plate and the second plug plate. The handle body can move up and down relative to the cover body. The limiting bolts and locking nuts play a role in fixing and limiting the handle body.

[0009] Preferably, a mounting and fixing hole is opened at a corner of the cover plate body, the mounting and fixing hole passes through the cover plate body, and the mounting and fixing hole is provided for mounting the cover plate body on the water distribution tray.

[0010] The handle insertion hole, installation fixing hole and limit hole are all processed at one time, with high dimensional accuracy and simple process.

[0011] Preferably, the first plug plate and the second plug plate are cut from the handle body and then bent into a U-shape.

[0012] Preferably, a sponge rubber strip is provided on one side of the limiting bolt below the cover plate body, and the sponge rubber strip plays a role of sealing to prevent water splashing.

[0013] Preferably, rounded corners are provided between the handle body and the first plug plate and the second plug plate to prevent the sharp edges of the handle body from scratching the staff.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The entire system of the utility model cleverly uses the deadweight of the handle to achieve concealment. Under normal conditions, the handle body falls to the upper surface of the water distribution tray cover body due to its deadweight and fits with it. By lifting the handle body to a set height, the limit bolts on the handle body play a limiting role to prevent the handle body from falling off the cover body. It has the characteristics of simple structure, easy installation, stable operation, etc. The entire water distribution tray cover system perfectly realizes the flexible switching between using and not using the handle.
