Description

Technical Field

[0001] This utility model relates to the field of water-saving irrigation technology, and in particular to an adjustable device for suppressing water consumption due to evaporation from the water surface of a channel. Background Technology

[0002] In agricultural irrigation and water conservancy projects, water surface evaporation during canal water conveyance leads to severe water resource losses, especially in arid regions. Currently, common methods for suppressing evaporation include chemical covering, physical shading, and fixed shading structures, but these methods all have significant limitations.

[0003] While chemical covering is simple to operate, it lacks persistence and may impact aquatic ecosystems. Physical shielding methods such as floats or plastic films can reduce evaporation, but they also hinder the normal exchange of water and air and affect channel maintenance operations. Traditional fixed shading devices mostly lack adjustability, making it difficult to adapt to changes in the angle of sunlight in different seasons. They are also complex to install and cannot meet the needs of evaporation inhibition and water ecological balance, resulting in limited practical application effects. Utility Model Content

[0004] This invention provides an adjustable device for suppressing water consumption through evaporation from the channel surface, aiming to solve the problem mentioned above of the poor adaptability of existing channel water-saving shielding devices to different channels, different light conditions, and environments.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An adjustable device for suppressing water consumption due to evaporation from a channel includes two rotating components and two limiting components arranged opposite to each other on both sides of the channel. One end of a baffle plate is rotated with the side of the channel through the rotating components, and the other end of the baffle plate moves between the limiting components. Both sides of the baffle plate are provided with brakeable sliding components. When the sliding components are braked, they form a fixed engagement with the baffle plate, and the sliding components form a releaseable locking engagement through the limiting components on the corresponding sides.

[0006] Preferably, the shielding plate includes an annular shielding frame, with a light-shielding plate in the middle of the shielding frame, one end of the shielding frame located between the rotating components, and the other end of the shielding frame located between the limiting components.

[0007] More preferably, the top of the shielding frame on the side away from the rotating member is provided with a handle.

[0008] More preferably, the rotating component is a hinge seat, which is fixed to the side of the channel by an anchor rod. Both ends of the shielding frame are provided with a rotating shaft that rotates and engages with the hinge seat on the corresponding side. During rotation, the shielding frame shields the channel.

[0009] More preferably, the sliding member includes a U-shaped slider with the slider opening sleeved on the side of the shielding frame and forming a sliding fit with the side of the shielding frame. Fastening screw holes are provided on both sides of the slider on both sides of the opening, and fastening screws are threaded into the fastening screw holes. The shielding frame is clamped and fixed between the fastening screws, and the slider forms a fixed fit with the shielding frame through the fastening screws.

[0010] Furthermore, both sides of the opening of the slider are provided with inwardly recessed and extending extension blocks, and the side of the shielding frame is provided with a sliding groove corresponding to the extension block. The extension block is limitedly embedded in the corresponding sliding groove and slides along the sliding groove.

[0011] Furthermore, each of the limiting components includes a vertically arranged vertical plate. The vertical plates of two limiting components are arranged opposite each other, and a limiting opening is formed between the vertical plates. The shielding frame and the sliders on both sides are located inside the limiting opening. Several limiting screw holes are provided on the vertical plate along the vertical direction. The internal threads of the limiting screw holes are fitted with limiting screws. The limiting screws on the two vertical plates are symmetrically arranged with the cap end facing outward from the limiting opening and the thread end facing inward from the limiting opening. The shielding frame and the sliders on both sides are clamped and fixed between the limiting screws.

[0012] Furthermore, the slider has a clamping hole on one side of the bottom of the opening. When the clamping hole coincides with the limiting screw hole, the limiting screw passes through the limiting screw hole and is embedded in the clamping hole to form a limiting fit. The end of the limiting screw forms a clamping fit with the bottom of the clamping hole.

[0013] Furthermore, the bottom of the vertical plate is provided with a base, the vertical plate is perpendicular to the base, and the base is fixed to the side of the channel that is not on the same side as the rotating component by anchor rods.

[0014] Furthermore, the limiting screw holes correspond one-to-one with the tilt angle of the shielding frame.

[0015] The beneficial effects of this utility model are: (1) The device can adjust the opening angle at will within a set angle range around the rotating component, thereby adapting to the channel span, lighting and other conditions, so that the shield can be opened at a certain angle and avoid complete blocking, suppressing evaporation and water consumption while ensuring water exchange with air and ensuring good channel water quality. (2) The entire installation is detachable. When fixing, the sliding component is first clamped and fixed on the baffle plate by the fastening screws, and then the sliding component and the baffle plate are clamped and fixed together between the limit screws. The fastening is all done by clamping, which is convenient for adjustment and installation and ensures the strength of the fastening. (3) The device is simple in design, easy to carry, low in cost, and easy to install in a modular manner along the channel. Attached Figure Description

[0017] The embodiments will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown in the preferred embodiment 1, an adjustable device for suppressing water consumption due to evaporation on the channel surface includes two rotating members 1 and two limiting members 3 arranged opposite to each other on both sides of the channel. One end of the baffle plate 4 forms a rotational engagement with the side of the channel through the rotating member 1, and the other end of the baffle plate 4 moves between the limiting members 3. Both sides of the baffle plate 4 are provided with brakeable sliding members 2. When the sliding member 2 is braked, it forms a fixed engagement with the baffle plate 4, and the sliding member 2 forms a releaseable locking engagement through the limiting members 3 on the corresponding side.

[0019] The shielding plate 4 includes an annular shielding frame 401, with a light-shielding plate 402 in the middle of the shielding frame 401. One end of the shielding frame 401 is located between the rotating members 1, and the other end of the shielding frame 401 is located between the limiting members 3. To ensure light blocking, when rotated to the corresponding position, the limiting members 3 are used to tighten and maintain the current angle.

[0020] The rotating component 1 is a hinge 101, which is fixed to the side of the channel by anchor rods. The ends of the shielding frame 401 are each provided with a rotating shaft that rotatably engages with the corresponding hinge 101. During rotation, the shielding frame 401 shields the channel, ensuring adjustment.

[0021] The sliding component 2 includes a U-shaped slider 201. The slider 201 is sleeved on the side of the shielding frame 401 and forms a sliding fit with the side of the shielding frame 401. The two side walls of the slider 201 on both sides of the opening are provided with fastening screw holes 204. Fastening screws 205 are threaded into the fastening screw holes 204. The shielding frame 401 is clamped and fixed between the fastening screws 205, and the slider 201 forms a fixed fit with the shielding frame 401 through the fastening screws 205.

[0022] Each limiting component 3 includes a vertically arranged vertical plate 301. The vertical plates 301 of the two limiting components 3 are arranged opposite each other, and a limiting opening 302 is formed between the vertical plates 301. The shielding frame 401 and the sliders 201 on both sides are located inside the limiting opening 302. A number of limiting screw holes 303 are provided on the vertical plate 301 along the vertical direction. The internal threads of the limiting screw holes 303 are fitted with limiting screws 304. The limiting screws 304 on the two vertical plates 301 are symmetrically arranged with the cap end facing outward from the limiting opening 302 and the thread end facing inward from the limiting opening 302. The shielding frame 401 and the sliders 201 on both sides are clamped and fixed between the limiting screws 304.

[0023] In use, the slider 201 can slide freely along the shielding frame 401, making it easy to adjust its position so that the slider 201 is aligned with the limiting screw 304. When the shielding plate 4 is rotated to the middle position of its side and corresponds to the limiting screw hole 303, the set angle is almost reached. At this time, the slider 201 can be slid to the position corresponding to the limiting screw 304, and the fastening screw 205 can be tightened to fix the slider 201, so that the slider 201 and the shielding plate 4 form a linkage. The limiting screw 304 clamps the slider 201 and the shielding plate 4 from opposite directions to avoid damage to the shielding plate during clamping and fixation, while ensuring the fixation strength.

[0024] As a preferred embodiment 2, the light-shielding plate 402 can be made of a high-reflectivity material, such as a plate treated with a TiO2-based coating.

[0025] In a preferred embodiment 3, the top of the shielding frame 401 on the side away from the rotating member 1 is provided with a handle 403. The handle 403 facilitates lifting the shielding plate 4, making it easy to change the tilt angle of the shielding plate 4.

[0026] As a preferred embodiment 4, both sides of the opening of the slider 201 are provided with inwardly recessed and extending extension blocks 203, and the side of the shielding frame 401 is provided with a sliding groove 202 corresponding to the extension blocks 203. The extension blocks 203 are limitedly embedded in the corresponding sliding grooves 202 and slide along the sliding grooves 202.

[0027] To ensure the sliding direction of slider 201, the slide groove 202 is parallel to the blocking frame 401, so that slider 201 only slides along the side of the blocking frame 401. At the same time, it has a limiting effect on slider 201, preventing slider 201 from falling off the blocking frame 401 when sliding.

[0028] As a preferred embodiment 5, the slider 201 is provided with a pressing hole 206 on one side of the bottom of the opening. When the pressing hole 206 coincides with the limiting screw hole 303, the limiting screw 304 passes through the limiting screw hole 303 and is embedded in the pressing hole 206 to form a limiting fit, and the end of the limiting screw 304 forms a pressing fit with the bottom of the pressing hole 206.

[0029] Typically, the clamping hole 206 is located in the middle of one side of the bottom of the opening, corresponding to the middle position of the shielding frame 401.

[0030] The clamping hole 206 further ensures the stability of the clamping and fixing. It can limit the limit screw 304. When the limit screws 304 on both sides are inserted into the corresponding clamping hole 206, they form a limit to prevent relative displacement after clamping, thereby further improving the stability of clamping. At the same time, it is convenient to align. When aligning, the clamping hole 206 is aligned with the limit screw hole 303. Then, the fastening screw 205 and the limit screw 304 are fixed in sequence to fix the whole piece completely.

[0031] In a preferred embodiment 6, the bottom of the vertical plate 301 is provided with a base, the vertical plate 301 is perpendicular to the base, and the base is fixed to the channel side not on the same side as the rotating component 1 by anchor rods. This ensures the fixed installation of the limiting component 3.

[0032] In a preferred embodiment 7, the limiting screw hole 303 corresponds one-to-one with the tilt angle of the shielding frame 401. For example, the limiting screw hole 303 tilted at about 60° is a fixed point. When it needs to be adjusted to 60°, it can be adjusted and fixed to this point.

[0033] As a preferred embodiment 8, a standard line is provided at the middle position of the side of the shielding frame 401 for quick alignment.

[0034] The working principle of this utility model: In use, the slider 201 can slide freely along the shielding frame 401, making it easy to adjust its position so that the slider 201 is aligned with the limiting screw 304. Select the required tilt angle and find the corresponding point, i.e., the limiting screw hole 303. Rotate the middle position of the shielding frame 401 to correspond with the required limiting screw hole 303, almost reaching the set angle. At this time, the slider 201 can be slid until the clamping hole 206 corresponds with the limiting screw 304. Tighten the fastening screw 205 to fix the slider 201, so that the slider 201 and the shielding plate 4 form a whole. Then tighten the limiting screw 304 to insert it into the corresponding clamping hole 206 and clamp the slider 201 and the shielding plate 4 in opposite directions to avoid damaging the shielding plate during clamping and fixation, while ensuring the fixation strength, and completing the angle fixation.
