Description

Technical Field

[0001] This utility model belongs to the technical field of sedimentation tanks, and specifically relates to a protective structure for high-density sedimentation tanks. Background Technology

[0002] In urban wastewater treatment plants, high-density sedimentation tanks are the final stage of the water treatment process. To improve water treatment capacity, these tanks are equipped with inclined tubes, inclined plates, and overflow weirs. However, this also provides more attachment sites for the growth of Spirogyra and algae. The higher the intensity and the longer the duration of sunlight exposure, the easier it is for Spirogyra and algae to proliferate, making cleaning difficult and reducing the performance of the sedimentation tank, affecting the quality of the effluent and causing it to fail to meet standards.

[0003] To reduce sunlight exposure to high-density sedimentation tanks, installing motorized sunshades is a simple and effective modification method. When unfolded, they provide shade; when folded for storage, they facilitate tank cleaning. Existing technologies such as CN213942196U and CN215916533U demonstrate feasible sunshade protection methods for high-density sedimentation tanks. However, these methods typically create a flat canopy directly above the tank when unfolded, offering good shading at midday. When sunlight is at an angle, the shading effect is limited and cannot effectively maintain shading throughout the entire duration of sunlight. Furthermore, the ease of connection, stability, and standardized construction of the shading devices require further optimization and improvement. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a protective structure for high-density sedimentation tanks, so as to avoid the problem that existing shading devices cannot effectively maintain the shading effect of high-density sedimentation tanks throughout the entire sunshine period.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A high-density sedimentation tank protection structure includes a sedimentation tank, with parallel guide rails on both sides of the sedimentation tank extending along the length of the sedimentation tank; the guide rails are equipped with unfoldable and retractable sunshade devices; the sunshade devices have two side facades, two end facades, and a top surface, and sunshade membrane cloth is laid on the side facades, end facades, and top surface of the sunshade devices.

[0006] To further improve the above technical solution, the shading film cloth laid on the side facade, end facade and top surface of the shading device is a whole structure.

[0007] Furthermore, self-tapping screws are sequentially passed through rigid washers, waterproof pads, and sunshade film to connect to the outer side of the side, end, or top surface of the sunshade device.

[0008] Furthermore, the sunshade device includes multiple truss modules arranged sequentially along the length of the guide rail. Each truss module includes a beam unit and two column units. The beam unit includes a horizontal beam with an arc-shaped crossbeam connected to it. The two ends of the crossbeam are fixedly connected to the upper surfaces of the two ends of the horizontal beam. Vertically downward-extending insertion columns are fixedly connected to the lower surfaces of the two ends of the horizontal beam. The column unit includes a vertical riser. The insertion columns at both ends of the beam unit are respectively inserted and connected to the upper ends of the vertical risers of the two column units. The lower ends of the vertical risers are connected to a roller mechanism and placed on the corresponding guide rails through the roller mechanism.

[0009] Furthermore, the guide rail adopts an I-beam structure and includes two parallel and facing wing plates and a web plate connected between the two wing plates. The web plate is vertically arranged, and a guide tube of the same length as the guide rail is laid on the upper wing plate. The roller mechanism includes a base plate fixed to the bottom end of the vertical tube. The base plate is connected to two parallel and facing side plates. A rotating shaft is connected between the two side plates. A roller is provided on the rotating shaft. The outer circumferential surface of the roller is concave and adapted to the guide tube. The roller is rolled on the guide tube through the arc-shaped outer circumferential surface. The lower edge of the side plate is lower than the upper wing plate and is vertically connected to an anti-tipping component extending toward the web plate.

[0010] Furthermore, among the multiple truss modules arranged sequentially along the length of the guide rail, the two truss modules at the ends are fixedly connected by a transverse connector to form a first end assembly and a second end assembly, respectively. The second end assembly is restricted from movement and is located at one end of the guide rail. The first end assembly is provided with an electric drive mechanism for driving the first end assembly to slide back and forth along the guide rail. The first end assembly, the second end assembly, and each truss module in between are sequentially connected to each other by corresponding hinged scissor frames.

[0011] Furthermore, the electric drive mechanism includes an electric drive housing connected between two vertical risers on the same side of the first end assembly. A motor and a rotatable traveling wheel are fixed inside the electric drive housing. The motor drives the traveling wheel, and the outer circumferential surface of the traveling wheel is also concave arc-shaped and rolls on the guide tube.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The high-density sedimentation tank protection structure of this utility model can avoid the problem that existing shading devices cannot effectively maintain the shading effect of high-density sedimentation tanks throughout the entire sunshine period, and the effect is better.

[0013] 2. The high-density sedimentation tank protection structure of this utility model avoids the problems of low modularity and low standardization of assembly construction of existing sunshade devices by using, building and assembling truss modules, thus achieving a simplified structure and more stable and reliable use.

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Please see Figures 1-8 The high-density sedimentation tank protection structure of a specific embodiment includes a square sedimentation tank 100. Parallel guide rails 1 are respectively provided on the two side banks of the sedimentation tank 100, and the guide rails 1 extend along the length of the sedimentation tank 100. A sunshade device 200 that can be unfolded and stored is provided on the guide rails 1. The sunshade device 200 has two parallel and facing side facades, two parallel and facing end facades, and a top surface connected above the end facades and side facades. Sunshade membrane fabric 2 is laid on the side facades, end facades, and top surface of the sunshade device 200.

[0017] In this embodiment, the drainage plant has four parallel sedimentation tanks, all of which are equipped with shading devices 200. This avoids the problem that the existing shading devices 200 cannot effectively maintain the shading effect of the high-density sedimentation tanks throughout the entire sunshine duration, resulting in better performance.

[0018] In implementation, if the manufacturing process of the shading membrane 2 allows, the shading membrane 2 laid on the side, end, and top surfaces of the shading device 200 can be a single, integral structure, resulting in better integrity. The shading membrane 2 uses existing flexible shading fabric materials, allowing it to expand and retract synchronously with the extension and retraction of the shading device 200. Specific examples of the material will not be provided here. Figure 2 and Figure 16 The extension and retraction states of the sunshade device 200 are shown respectively.

[0019] Please see Figure 9When fixing the sunshade membrane 2, self-tapping screws 6 are used to pass through the rigid washer 61, the waterproof pad 62, and the sunshade membrane 2 in sequence, and are connected to the outer side surface, end surface, or top surface of the sunshade device 200. The rigid washer 61 and the waterproof pad 62 are circular. The rigid washer 61 can be pre-drilled in the center. After the self-tapping screw 6 passes through the waterproof pad 62 and the sunshade membrane 2 with its tip, it is threaded into the pre-set internal thread hole on the outer side surface of the sunshade device 200 and tightened. The head of the screw presses the rigid washer 61, the waterproof pad 62, and the sunshade membrane 2 together.

[0020] Please continue reading Figure 4 , Figures 10-12 The sunshade device 200 includes multiple truss modules 3 arranged sequentially along the length of the guide rail 1. Each truss module 3 includes a beam unit 31 and two column units 32. The beam unit 31 includes a horizontal beam 311 with an arc-shaped crossbeam 312 connected to it. The two ends of the crossbeam 312 are fixedly connected to the upper surfaces of both ends of the horizontal beam 311. Vertically downward-extending insertion columns 313 are fixedly connected to the lower surfaces of both ends of the horizontal beam 311. The crossbeam 312 above it and the plug-in columns 313 at both ends are all located in the same vertical plane; the column unit 32 includes a vertical riser 321, and the plug-in columns 313 at both ends of the crossbeam unit 31 are respectively inserted into the upper end of the vertical riser 321 of the two column units 32. Specifically, the plug-in column 313 is inserted into the inner hole of the vertical riser 321 from the upper end of the vertical riser 321, and the lower end of the vertical riser 321 is connected to a roller mechanism 5, and is rolled on the corresponding guide rail 1 through the roller mechanism 5.

[0021] By using, building, and assembling truss module 3, the problems of low modularity and low standardization of assembly construction in existing sunshade structures are avoided, thus achieving the effect of simplifying the structure.

[0022] Please see Figure 12 , Figure 13The guide rail 1 adopts an I-beam structure and includes two parallel and facing wing plates 11 and a web plate 12 connected between the two wing plates 11. The web plate 12 is vertically arranged, and a guide tube 13 of the same length as the guide rail 1 is laid on the upper wing plate 11, located in the middle of the wing plate. The roller mechanism 5 includes a base plate 51 fixed to the bottom end of the vertical riser 321. The base plate 51 is connected to two parallel and facing side plates 52. The side plates 52 are parallel to the web plate 12. A rotating shaft 53 is connected between the two side plates 52. A roller 54 is provided on the rotating shaft 53. The outer circumferential surface of the roller 54 is concave arc and adapted to the guide tube 13. The roller 54 is rolled on the guide tube 13 through the arc-shaped outer circumferential surface. The vertical distance between the two side plates 52 is greater than the width of the wing plate 11. The lower edge of the side plate 52 is lower than the upper wing plate 11 and is vertically connected to an anti-overturning member extending toward the web plate 12. The distance between the inner end of the anti-rollover component and the web plate 12 should be smaller than the distance between the outer edge of the wing plate 11 and the web plate 12, forming an interlocking shape, which can improve stability under lateral forces such as wind. The anti-rollover component can be formed by bending the lower edge of the side plate 52 inward at 90°, or it can be a riveted inwardly extending pin, whichever is more specific.

[0023] Please see again. Figure 4 Among the multiple truss modules 3 arranged sequentially along the length of the guide rail 1, the two truss modules 3 closest to the two ends (outermost) of the guide rail 1 are fixedly connected by a transverse connector 71. A first end assembly 7 and a second end assembly 8 are formed at both ends of the guide rail 1, respectively. The second end assembly 8 is restricted from movement and is located at one end of the guide rail 1. The first end assembly 7 is provided with an electric drive mechanism 9 for driving the first end assembly 7 to slide back and forth along the guide rail 1. The first end assembly 7, the second end assembly 8, and each truss module 3 in between are sequentially connected to each other by corresponding hinged scissor frames 10. Specifically, hinged scissor frames 10 are provided between adjacent crossbeams and between adjacent vertical risers 321. The second end assembly 8 is restricted from movement and is located at one end of the guide rail 1, that is, fixed to one end of the sedimentation tank. The specific method can be to use existing means, such as restricting the rolling of the roller 54, or adding a blocking component to the guide rail 1, etc., without specific restrictions.

[0024] Please continue reading Figure 4 , Figure 14 and Figure 15The electric drive mechanism 9 includes an electric drive housing 91 connected between two vertical risers 321 on the same side of the first end assembly 7. The lower end of the electric drive housing 91 is open. A motor 92 and a rotatable traveling wheel 95 are fixed inside the electric drive housing 91. The motor 92 drives the traveling wheel 95. The outer circumferential surface of the traveling wheel 95 is also concave arc-shaped and adapted to the guide tube 13. The traveling wheel 95 is rolled on the guide tube 13 through the arc-shaped outer circumferential surface. Specifically, the output shaft of the motor 92 is fixedly connected to the drive gear 93, and the walking wheel 95 is connected to the electric drive housing 91 through a rotating shaft (not shown in the figure). There is also a driven gear 94 that rotates synchronously with the walking wheel 95 on the rotating shaft. The drive gear 93 and the driven gear 94 mesh and drive each other, thereby driving the driven gear 94 and the walking wheel 95, and driving the first end assembly 7 to move on the guide rail 1. When unfolded, it unfolds in sequence through the hinged scissor frame 10 and pulls the adjacent truss module 3 to move, unfolding the sunshade film 2. When the first end assembly 7 is driven to move on the guide rail 1 in the reverse direction, the sunshade film 2 is stored. The first end assembly 7 corresponds to the two guide rails 1, and is equipped with an electric drive mechanism 9 on both sides. When the traveling wheel 95 of the first end assembly 7 falls on the guide tube 13, the bottom of the four rollers 54 should be slightly higher than the bottom of the traveling wheel 95 to ensure effective contact and driving between the traveling wheel 95 and the guide tube 13. During operation, the relative height between the traveling wheel 95 and the rollers 54 can be determined during the fixed connection, or the electric drive housing 91 can be raised and lowered to the first end assembly 7, thereby facilitating the adjustment of the relative height between the traveling wheel 95 and the rollers 54. In this embodiment, an auxiliary traveling wheel 96 is also rotatably provided inside the electric drive housing 91. It is spaced apart from the traveling wheel 95 along the length of the guide rail 1, adopts the same structure as the traveling wheel 95, has the same height, does not require a drive connection, and rolls synchronously with the traveling wheel 95 to contact the guide tube 13, playing a role in maintaining a smoother driving operation.

[0025] Please continue reading Figure 4 , Figure 10 In implementation, to improve stability, a horizontal beam stiffener 313 can be vertically connected between the horizontal beam 311 and the span beam 312 of the beam unit 31; the vertical riser 321 can be a square tube (the corresponding insertion column 313 is also square), or a round tube with lower cost. When using a round tube, to prevent torsion, a detachable diagonal stiffener 33 can be bolted between the horizontal beam 311 and the vertical riser 321 of the truss module 3; the truss module 3 on the outer side of the first end assembly 7 and the second end assembly 8 experiences the most complex stress and environmental conditions, and a connecting horizontal stiffener 72 can be added between the lower parts of the two vertical risers 321 of the corresponding truss module 3. A vertical stiffener 73 can also be connected between the horizontal stiffener 72 and the upper horizontal beam 311. The span beams 312 of each truss module 3 collectively form the top surface of the sunshade device 200 (e.g., Figure 3The side facade of the sunshade device 200 is formed by the vertical risers 321 of each truss module 3 (e.g., Figure 2 The end facades of the sunshade device 200 are formed by the truss modules 3 on the outer sides of the first end assembly 7 and the second end assembly 8, respectively. Figure 1 The self-tapping screws 6 are connected to the pre-set internal threaded holes on each structural component. The number and position are as follows, based on the requirement of effectively fixing the sunshade film 2, without specific restrictions.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
