Description

Technical Field

[0001] This utility model relates to the technical field of water storage tank equipment, and in particular to a water storage tank anti-evaporation device. Background Technology

[0002] Reservoirs are pools used to store irrigation water for use during the dry season, facilitating the delayed use of water resources and thus enabling planned water resource utilization. Most reservoirs are built outdoors with large openings, resulting in a large water surface area and increased evaporation surface area. When sunlight shines on the water surface, it raises the water temperature, accelerating evaporation and causing significant water loss during irrigation. Utility Model Content

[0003] The purpose of this utility model is to provide a water storage tank anti-evaporation device, which can cover the surface of the water in the water storage tank, thereby preventing sunlight from directly shining on the water surface, reducing the evaporation area of ​​the water body, effectively reducing the evaporation rate of the water in the water storage tank, and reducing the amount of evaporation.

[0004] To achieve the above and other related objectives, this utility model provides a water storage tank anti-evaporation device, comprising: an anti-evaporation membrane and a traction assembly. The anti-evaporation membrane covers the surface of the water in the water storage tank. The anti-evaporation membrane includes an opaque layer and a low-density layer. The bottom surface of the opaque layer is fixedly connected to the top surface of the low-density layer, and the low-density layer is in contact with the water in the water storage tank. The traction assembly includes four traction seats. One traction seat is fixedly installed at each end of the diagonal direction of the water storage tank. A traction roller and a first pulley assembly are rotatably installed on each traction seat. A traction rope is laid along the diagonal direction of the anti-evaporation membrane. The two ends of each traction rope are fixedly connected to two traction rollers on two oppositely arranged traction seats. Several second pulley assemblies are installed on the top of the anti-evaporation membrane along the diagonal direction. Each traction rope is slidably connected to two first pulley assemblies and several second pulley assemblies. A crank handle and a tension adjustment device are fixedly installed at both ends of each traction roller. Several counterweights are fixedly installed at the bottom of the anti-evaporation membrane.

[0005] In one example of the anti-evaporation device for a water storage tank of this utility model, the opaque layer and the low-density layer are bonded and fixed by hot pressing.

[0006] In one example of the anti-evaporation device for water storage tanks of this utility model, the low-density layer contains a number of closed pore structures.

[0007] In one example of the anti-evaporation device for a water storage tank of this utility model, two traction roller supports are fixedly installed on the top of the traction seat. The two ends of the traction roller shaft are rotatably connected to the top of the two traction roller supports respectively. The tension adjustment device includes a magnetic powder brake and a tension regulator. The magnetic powder brake is fixedly installed on the top of the surface of one of the traction roller supports away from the traction roller. The output end of the magnetic powder brake is fixedly connected to one end of the traction roller shaft. The magnetic powder brake is electrically connected to the tension regulator.

[0008] In one example of the anti-evaporation device for a water storage tank according to this utility model, the first pulley assembly includes two first pulleys, a first pulley frame, and a second pulley frame. The traction roller bracket is fixedly installed on the top surface of the traction seat at the end away from the water storage tank. The second pulley frame is fixedly installed on the top surface of the traction seat at the end facing the water storage tank. The first pulley frame is fixedly installed on the top surface of the traction seat between the traction roller bracket and the second pulley frame. The height of the first pulley frame is lower than the height of the second pulley frame. The two first pulleys are respectively rotatably installed on the top of the first pulley frame and the second pulley frame.

[0009] In one example of the anti-evaporation device for a water storage tank according to this utility model, the second pulley assembly includes a second pulley and a third pulley frame. The second pulley is rotatably mounted on the top of the third pulley frame, and the bottom of the third pulley frame is fixedly connected to the anti-evaporation membrane.

[0010] In one example of the anti-evaporation device for a water storage tank of this utility model, 4 to 8 second pulley assemblies are evenly provided along each diagonal direction of the anti-evaporation membrane.

[0013] This utility model relates to an anti-evaporation device for water storage tanks. The anti-evaporation membrane is laid and covered on the surface of the water in the tank. The opaque layer at the top of the membrane prevents sunlight from reaching the water surface, while the low-density layer allows the membrane to float, thus lowering the water surface temperature and reducing the evaporation area. This effectively reduces the evaporation rate and amount of water in the tank. The traction component pulls the membrane, ensuring it remains in contact with the water surface. Four traction seats are fixedly installed at both ends of two diagonal lines of the tank, and two traction ropes extend along the anti-evaporation membrane... The membrane is arranged along two diagonal directions. Two traction ropes are slidably connected to several second pulley assemblies at the top of the anti-evaporation membrane, thereby providing an upward traction force to the anti-evaporation membrane. The two traction ropes can also pull and unfold the edges and corners of the anti-evaporation membrane to prevent it from gathering in one place and exposing the water surface. The unwinding tension of the traction roller can be adjusted by a tension adjustment device, thereby adjusting the traction force of the traction ropes. The first pulley assembly can guide the traction ropes. Several counterweights at the bottom of the anti-evaporation membrane can balance the traction force of the traction ropes and also play a certain role in wind protection.

[0018] Please see Figures 1 to 6 This utility model provides a water storage tank anti-evaporation device, which includes: an anti-evaporation membrane 100 and a traction component 200. The anti-evaporation membrane 100 covers the surface of the water in the water storage tank 400. The anti-evaporation membrane 100 includes an opaque layer 110 and a low-density layer 120. The bottom surface of the opaque layer 110 is fixedly connected to the top surface of the low-density layer 120. The low-density layer 120 is in contact with the water in the water storage tank 400. The traction assembly 200 includes four traction seats 210. One traction seat 210 is fixedly installed at each of the two ends of the diagonal direction of the water storage tank 400. A traction roller 220 and a first pulley assembly 230 are rotatably installed on each traction seat 210. A traction rope 260 is laid along the diagonal direction of the anti-evaporation membrane 100. The two ends of each traction rope 260 are fixedly connected to two traction rollers 220 on two oppositely arranged traction seats 210. Several second pulley assemblies 240 are installed at the top of the anti-evaporation membrane 100 along the diagonal direction.

[0019] The anti-evaporation membrane 100 of this invention is laid and covered on the surface of the water in the reservoir 400. The opaque layer 110 on top of the anti-evaporation membrane 100 can prevent sunlight from shining on the water surface, and the low-density layer 120 can make the anti-evaporation membrane 100 float on the water surface, thereby lowering the water surface temperature and reducing the evaporation area of ​​the water body, effectively reducing the evaporation rate of the water in the reservoir 400 and reducing the amount of evaporation. The traction assembly 200 can traction the anti-evaporation membrane 100, keeping it in contact with the water surface.

The tension adjustment device 250 can adjust the unwinding tension of the traction roller 220, thereby adjusting the traction force of the traction rope 260. The first pulley assembly 230 can guide the traction rope 260. Several counterweights 300 at the bottom of the anti-evaporation membrane 100 can exert a downward force on the anti-evaporation membrane 100 through their own weight, which can balance the traction force of the traction rope 260 and also play a certain role in wind protection.

The crank handle 221 can drive the traction roller 220 to rotate, thereby retrieving the traction rope 260.
