Description

Technical Field

[0001] This invention relates to a light shield that can be opened and closed for the liquid surface of open equipment or pools, and more specifically to a light shielding facility for the liquid surface of open equipment or pools in the field of water treatment and its application method. Background Technology

[0002] As is well known, whether water is flowing or still, prolonged exposure to sunlight will cause a large amount of algae to grow and multiply on the surfaces and components of equipment. Even seeds of flowers and grasses blown by the wind can germinate and grow on the surface of the packing material in the tank. If the system is not stopped and cleaned in time, algae will clog the channels between the packing materials, affecting the normal operation of the equipment. In severe cases, algae can even crush the internal support structure of the equipment, causing the entire equipment to collapse. The most typical open water treatment equipment includes facilities such as inclined plate or inclined tube sedimentation tanks with enhanced mud-water separation functions, biological aerated filters (BAF), and media filters. These facilities require regular inspections during operation, as well as regular maintenance of internal components and replacement of damaged or ineffective packing materials. Therefore, they cannot be sealed and are mostly in an open state. To solve the problem of sunlight exposure in open facilities, a small number of facilities have steel-framed sunshades. However, in order to meet the lifting height requirements of the cranes for replacing internal packing materials, the roofs are made relatively high. This means that the roofs cannot block oblique and scattered sunlight most of the time, resulting in unsatisfactory shading effects.

[0003] Patent authorization number CN 209163016 U, "A convenient openable and closed louvered cover for a water tank," can satisfy the purpose of shading the surface of the water tank, but it has the following shortcomings:

[0004] The louvers lack wing plates or reinforcing ribs, and the blades are relatively narrow. The optimal blade width is claimed to be 150-200mm. This results in a larger amount of processing work on the blades, increasing the cost. Furthermore, the blades are only fixed to the rotating rod without any reinforcement measures, leading to poor overall strength and the possibility of tearing in strong winds.

[0005] The rotating rod is mounted in the bearing on the top of the channel steel. When it is necessary to replace the internal parts of the pool and the packing, the bearing covers and bearing seats at both ends need to be disassembled before the rotating rod and blades can be pulled out. When restoring, they need to be reinstalled and aligned, which is a lot of work. It is difficult to guarantee the concentricity of the bearings and the rotating shaft at both ends.

[0006] The connecting rod of the traction rotating arm is located on the upper part of the sunshade, and there is no limit setting. Misalignment of the connecting rod may cause the louver to fail to snap into the groove of the next louver, resulting in blade deformation or even damage.

[0007] The connecting rod is located on the upper part of the louvers. Dead branches and leaves blown by the wind will get tangled on the rotating arm and connecting rod, requiring frequent cleaning and a large amount of maintenance work. Summary of the Invention

[0008] This invention proposes a convenient, flexible, and robust light-shielding device that prevents algae in a pool from growing and multiplying in large quantities on the packing material or components inside the pool through photosynthesis. It is an open device or a light-shielding cover that can be opened and closed on the pool surface.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A light shield for an openable device or pool with a liquid level that can be opened and closed includes a light shield frame, blades on the light shield frame, the blades being movably mounted on the light shield frame via a rotating shaft, the blades being connected to a push rod mechanism, and the push rod mechanism being connected to a worm gear operating mechanism, the worm gear operating mechanism controlling the push rod mechanism to drive the blades to open and close on the light shield frame.

[0011] Preferably, the blade comprises a plurality of plates arranged side by side, with a spacing between the plates, the spacing between the plates conforming to the overlap width; each plate is provided with at least two wing plates, the rotating shaft passes through the wing plates on each plate, and welds the blade and the wing plates together; the two wing plates include wing plate one and wing plate two, wing plate one is connected to a push rod mechanism, and the push rod mechanism is connected to a worm gear operating mechanism.

[0012] Preferably, the push rod mechanism includes a push rod, a push rod connector, and a rotating bolt assembly. One end of the push rod is connected to a worm gear operating mechanism, and several push rod connectors are connected to the push rod. The push rod connectors are connected to the wing plate via the rotating bolt assembly.

[0013] Preferably, the push rod is provided with limiters at both ends. The limiters can prevent the push rod from being over-operated when pushing the blade to open or close, causing the blade to be squeezed and damaged.

[0014] Preferably, the sunshade frame is provided with channel steel on both sides, and the channel steel is C-shaped channel steel. The C-shaped channel steel has sufficient strength to support the weight of the entire sunshade and the load of rain and snow.

[0015] Preferably, the lower side of the channel steel has a groove structure, and the width of the groove is 1 to 3 cm wider than the upper side of the channel steel, for collecting rainwater that leaks from both ends of the blade.

[0016] Preferably, each channel steel of the light shield frame is provided with a pivot support plate on its upper side, and a pivot sleeve assembly is provided on the pivot support plate. The two ends of the pivot pass through the pivot sleeve assembly and do not exceed the inner edge of the pivot support plate. The pivot sleeve assembly is installed on the pivot support plate by a snap ring.

[0017] The present invention also provides a method for applying a light shield that can be opened and closed on open equipment or pools, the steps of which are as follows:

[0018] S1: The two sets of light-shielding frames are symmetrically erected on the top of the pool wall using support legs. In order to drain rainwater, the light-shielding should be tilted in the direction of the panel overlap.

[0019] S2: Weld the plate, two wing plates, and pivot together to form a whole, and install it on the pivot support plate of the sunshade frame.

[0020] S3: The wing plate is connected to the push rod connector through the rotating bolt assembly. The other end of the push rod connector is fixed on the push rod. The push rod is placed in the push rod limiter. The end of the push rod is fixed to the output crankshaft of the worm gear operating mechanism.

[0021] S4: Driven by the worm gear operating mechanism, the push rod is moved, which in turn drives the push rod connector to move, and causes the wing plate connected to the push rod connector to rotate on the rotating shaft, so that the blades on the light shield frame can be opened and closed.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The light shield provided by this invention covers the entire water surface, which can prevent algae in the pool from photosynthesizing under light and multiplying in large quantities on the surface of the filler material, clogging the pores of the filler material and preventing it from operating normally.

[0024] 2. The light shield provided by this invention can effectively prevent dead branches and leaves brought by air circulation from falling into the pool and affecting the normal operation of the components inside the pool.

[0025] 3. The light shield provided by the present invention is installed on the top of the outdoor pool. It can be arranged symmetrically on both sides or on one side according to the size of the pool. It can be set to a suitable tilt angle as needed, which not only facilitates the drainage of rainwater, but also prevents the liquid surface in the pool from being impacted by heavy rain and disturbing the flow of water in the pool.

[0026] 4. The light shield provided by this invention is composed of many blades, which can be easily opened at any time to observe the operating conditions inside the pool, so as to adjust the operating parameters of the facility and determine its maintenance plan;

[0027] 5.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] like Figures 2 to 4 As shown, the present invention provides a light shield that can be opened and closed for openable equipment or pool liquid surface, including a light shield frame 1, blades with special wing plates 2, a rotating shaft that drives the blades to rotate 3, a support plate that provides support for the rotating shaft of the blades 4, a rotating shaft sleeve assembly that allows easy disassembly of the rotating shaft and blades 5, a retaining ring that prevents the rotating shaft sleeve assembly from falling off 6, a push rod that pushes the light shield blades to open and close 7, a push rod connector that connects the push rod and the blade rotation 8, a bolt assembly between the connector and the wing plate 9, a limiter that limits the left and right and up and down movement of the push rod 10, and a worm gear operating mechanism with a crankshaft 11;

[0036] The blade 2 includes several plates 2-1 arranged side by side, and the plates 2-1 are spaced at the same distance, which is the width required to achieve the light-blocking effect when the plates 2-1 overlap with adjacent plates. A first wing plate 2-2 and a second wing plate 2-3 are welded at different longitudinal positions on each plate 2-1. The length of the first wing plate 2-2 and the second wing plate 2-3 is 20-40 mm smaller than the width of the plate 2-1, and the first wing plate 2-2 and the second wing plate 2-3 are symmetrically arranged about the center of the width of the plate 2-1.

[0037] The rotating shaft 3 passes through the first wing plate 2-2 and the second wing plate 2-3 on each plate 2-1, and welds the rotating shaft 3, blade 2, first wing plate 2-2 and second wing plate 2-3 into one piece; the first wing plate 2-2 is connected to the push rod mechanism, which is connected to the worm gear operating mechanism 11 with a crankshaft. The worm gear operating mechanism 11 with a crankshaft controls the push rod mechanism to drive the plates 2-1 on the first wing plate 2-2 connected to it to open (arranged side by side with spacing) and close (folded and overlapped) on the light shield frame 1.

[0038] Furthermore, the length and appropriate width of the plate 2-1 are set according to the different pool plane dimensions. The more economical length of the plate 2-1 is between 1000 and 2500 mm, and the width is between 200 and 400 mm. The overlap width of the plate 2-1 is preferably 10 to 20 mm. It can be a thin steel plate or a non-metallic material.

[0039] Furthermore, the number of wing plates depends on the length of the plates, generally 2 to 4. Wing plate 1 2-2 and wing plate 2-3 can be the same shape or different shapes. Wing plate 1 2-2 and wing plate 2-3 can be long strip plates of the same length.

[0040] The push rod mechanism includes a push rod 7, a push rod connector 8, and a rotating bolt assembly 9. One end of the push rod 7 is connected to the worm gear operating mechanism 11, and the push rod connector 8 is connected to the push rod 7. The push rod connector 8 is connected to the wing plate 2-2 via the rotating bolt assembly 9.

[0041] Furthermore, in order to reduce the overall weight of plate 2-1 as much as possible, the wing plate 2-2 is protruding in shape. A circular hole with a size equivalent to the outer diameter of the rotating shaft 3 and tangent to plate 2-1 is opened in the middle of the wing plate 2-2. Another circular hole is opened at an appropriate distance from the rotating shaft hole. The wing plate 2-2 is connected to the upper hole of the push rod connector 8 through the rotating bolt assembly 9. The other end of the push rod connector 8 is fixed to the push rod 7. One end of the push rod 7 is fixed to the worm gear operating mechanism 11 with crankshaft on the output side. The opening and closing function of the blade can be easily, flexibly and safely realized by shaking the worm gear operating mechanism 11.

[0042] Furthermore, limiters 10 are provided at both ends of the push rod 7. The push rod 7 is placed in the push rod limiters 10 at both ends of the frame. The push rod limiters 10 restrict the left and right and up and down movement space of the push rod 7. The limiters 10 can prevent the push rod 7 from being over-operated when pushing the blade 2 to open and close, causing the blade 2 to be squeezed and pulled out.

[0043] Furthermore, the sunshade frame 1 has channel steel 1-1 on both sides. The channel steel 1-1 is a C-shaped channel steel, which is processed by bending steel plates. The C-shaped channel steel not only has sufficient strength to support the weight of the entire sunshade and the load of rain and snow, but also has a groove structure on the lower side. The width of the groove is 2-3 cm wider than the upper side of the channel steel 1-1, which is used to collect light entering from the gaps between the blades 2 and to collect rainwater that leaks in. A rotating shaft support plate 4 with holes at certain intervals is welded to the top of the upper side of each C-shaped channel steel 1-1. The hole spacing is equivalent to the arrangement spacing of several plates 2-1, and the hole diameter is equivalent to the outer diameter of the rotating shaft sleeve assembly 5.

[0044] Furthermore, channel steel 1-1 can be made of isosceles channel steel or other structural steel of other shapes.

[0045] Two pivot support plates 4 are installed on the sunshade frame 1. The pivot 3 passes through the wing plate on each plate 2-1 and is supported at both ends on the pivot support plate 4 and passes through the pivot sleeve assembly 5. The pivot sleeve assembly 5 is installed on the pivot support plate 4 by a retaining spring 6. The two ends of the pivot 3 do not extend beyond the inner edge of the pivot support plate 4.

[0046] Furthermore, the shaft sleeve assembly 5 can also be fixed to the shaft support plate 4 with bolts.

[0047] like Figure 1 As shown, the present invention also provides a method for applying a light shield that can be opened and closed on open equipment or pools, the steps of which are as follows:

[0048] S1: The two sets of light-shielding frames are symmetrically erected on the top of the pool wall by supporting feet 12. In order to facilitate rainwater drainage, the light-shielding should be tilted in the direction of the panel overlap.

[0049] S2: Weld plate 2-1, the two wing plates, and the rotating shaft 3 together to form a whole, and install it on the rotating shaft support plate 4 of the sunshade frame 1.

[0050] S3: Wing plate 2-2 is connected to push rod connector 8 via rotating bolt assembly 9. The other end of push rod connector 8 is fixed on push rod 7. Push rod 7 is placed in push rod limiter 10. One end of push rod 7 is fixed to the output crankshaft of worm gear operating mechanism 11.

[0051] S4: Driven by the worm gear operating mechanism 11, the push rod 7 is moved, thereby driving the push rod connector 8 to move, and causing the wing plate 2-2 connected to the push rod connector 8 to drive the plate 2-1 to rotate on the rotating shaft 3, so that the blades 2 on the light shield frame 1 are in the open and closed state.

[0052] Furthermore, the angle of inclination of the sunshade in the direction of the panel overlap is not less than 5°. Figure 1In the diagram, E indicates the sunshade is open, and F indicates the sunshade is closed.

[0053] The parameters of the specific embodiments are described in detail below: Example

[0054] This invention designs a reinforced concrete pool with a planar dimension of 8500x6000 mm. The central operating platform features symmetrically arranged, openable and closable light shields. The central operating platform is 1800 mm wide. The light shields are mounted on the top of the pool wall and on columns along the sides of the central operating platform, with an inclination angle of 5 degrees. Three independent frame light shields are arranged side-by-side on each side. Each frame is approximately 2200 mm wide (considering the thickness of the pool wall), with a total length of approximately 4000 mm. The light shield blades are approximately 2000 mm long and 300 mm wide, with an overlap of 10 mm. Each frame requires 13 blades, for a total of 78 blades. Each blade has one wing plate 2-2 and one wing plate 2-3, symmetrically arranged on both sides of the blade.

[0055] Plate 2-1, shaft 3, blade 1 2-2, and blade 2 2-3 are welded together to form a whole, which is installed on the shaft support plate 4 on the upper side of the C-shaped channel steel of the frame. Blade 1 2-2 is connected to push rod connector 8 through rotating bolt assembly 9. The other end of push rod connector 8 is fixed to push rod 7. Push rod 7 is placed in push rod limiters 10 at both ends of the light shield. The length of push rod 7 is greater than the length of the light shield to ensure that push rod 7 will not slip outside the limiters 10 during the entire movement process. On the operating platform side, the end of push rod 7 is fixed to the crankshaft at the output end of worm gear operating mechanism 11. Push rod 7 is moved by shaking worm gear 1, which in turn transmits to push rod connector 8 to drive the rotation of blade 2, so that the operating conditions in the pool can be observed when the light shield blade 2 is open and the light is blocked when it is closed.

[0056] When replacing larger components or filling materials within the pool, the blades of the light shield need to be removed to allow for easy removal or repositioning of the components using lifting equipment. Remove the bolt assembly connecting the wing plate and push rod, remove the corresponding retaining ring on the shaft sleeve, and pull out the shaft sleeve assembly to remove the blades. After maintenance, reassemble them in the reverse order. Example

[0057] This invention designs a set of openable and closable light shields for a 7000x3000 mm reinforced concrete pool, arranged on one side. The operating platform is located on the shorter side of the pool. The light shields are mounted on supports on the top of the reinforced concrete wall on the shorter side of the pool wall, with an inclination angle of 5 degrees. Two sets of independent frame light shields are arranged side by side on site. Each frame is approximately 1800 mm wide (considering the thickness of the pool wall), with a total length of approximately 7400 mm. The length of the light shield blades is approximately 1600 mm, and the width is 300 mm. The overlap width of each blade is 10 mm. Each frame requires 25 blades, for a total of 50 blades. Each blade 2 is equipped with wing plate 2-2 and wing plate 2-3, symmetrically arranged on both sides of the blade.

[0058] Plate 2-1, shaft 3, and two wing plates are welded together to form a whole and installed on the upper shaft support plate 4 on the upper side of the C-shaped channel steel frame. Each wing plate is connected to the push rod connector 8 through the rotating bolt assembly 9. Two sets of push rods 7 and worm gear operating mechanisms 11 are symmetrically arranged. The other end of the push rod connector 8 is fixed to a push rod 7. Each push rod 7 is placed in the push rod limiter 10 at both ends of its respective light shield. The length of the push rod 7 must be greater than the length of the light shield to ensure that the push rod 7 will not slip outside the limiter 10 during the entire movement process. On the operating platform side, the end of each push rod 7 is fixed to the crankshaft of the output end of its corresponding worm gear operating mechanism 11. The push rod 7 is moved by shaking the worm gear 1, which in turn transmits the power to the push rod connector 8 to drive the rotation of plate 2-1, so that the light shield blades 2 can be opened to observe the operating conditions in the pool and closed to block the light.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
