Description

Technical Field

[0001] This utility model belongs to the technical field of anti-pollution screens for water construction, and in particular relates to a roller shutter type anti-pollution screen for water-related construction. Background Technology

[0002] In dredging and reclamation operations, pollution screens or curtains are often used to protect the environment and control the spread of sediment and pollutants during construction. These facilities primarily limit the propagation of suspended sediment in the water body through physical barriers, thereby reducing the impact on surrounding water areas and ecosystems. Pollution screens or curtains are typically made of corrosion-resistant and anti-aging synthetic materials and are designed with appropriate floating and anchoring systems to adapt to different water conditions.

[0003] The design of antifouling screens or curtains mainly encompasses material selection, sizing, placement strategies, and maintenance methods. For example, to ensure effectiveness, these screens or curtains need to be long enough to cover the entire construction area, and their bases are often weighted to ensure vertical stability. Furthermore, the installation process must consider the effects of tides and water flow to ensure stable operation of the antifouling facilities under varying environmental conditions. Through these measures, antifouling screens or curtains effectively control the spread of pollutants in the water, helping dredging and reclamation projects meet environmental standards, reducing negative environmental impacts, and protecting the habitat of aquatic life. These facilities are one of the important tools for achieving green construction.

[0004] Regarding the arrangement, installation, and recycling of anti-fouling screens or curtains, they should be rationally arranged according to the specific needs of the construction area to ensure maximum coverage and effective isolation. It is also essential to ensure that the anti-fouling screens or curtains are securely installed during construction and their integrity and functionality should be checked regularly, with repairs or replacements carried out as necessary.

[0005] However, the installation and retrieval of current anti-fouling screens or curtains are quite troublesome and time-consuming during construction, especially when it comes to underwater work. The complexity of the underwater environment further increases the workload and difficulty for construction personnel. Therefore, designing an anti-fouling screen or curtain that is easy to install and disassemble without affecting the anti-fouling effect has great practical engineering significance. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model proposes a roller shutter-type anti-pollution screen for water-related construction that can prevent the spread of pollution, protect the environment, and is easy to lay and automatically recycle. It is mainly used in water-related construction, and is convenient for underwater installation and recycling, especially when the project is completed.

[0007] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] A roller shutter-type anti-fouling screen for water-related construction, including an anti-fouling roller shutter;

[0009] It also includes a torsion spring mechanism, a float and a counterweight. The torsion spring mechanism includes a torsion bar, a spring and a spring box. The anti-fouling roller shutter is rolled up on the torsion bar. The spring is set in the spring box. The left and right ends of the torsion bar are respectively inserted into a spring box and connected to the inner end of the spring inside. The outer end of the spring is curled and inserted into the protective slot in the spring box, so that when the torsion bar rotates, it will drive the spring to tighten. Similarly, when the spring rebounds, it will drive the torsion bar to reverse.

[0010] A float is attached to the top of each end of the torsion bar, and a counterweight is detachably connected to the head of the anti-fouling roller shutter.

[0011] In the above technical solution, preferably, at least two protective slots are provided inside the spring box along the circumferential direction, so that when the load loaded on the spring is too large and exceeds the limit, the outer end of the spring will slide down into another protective slot as it deforms.

[0012] In the above technical solution, preferably, both ends of the torsion bar are disc surfaces, and the two disc sides of the torsion bar are provided with slots composed of two clamping plates. Both ends of the torsion bar are connected to the spring box, the slots composed of clamping plates extend into the inside of the spring box, and the inner end of the spring is inserted into the slots composed of clamping plates.

[0013] In the above technical solution, preferably, the anti-fouling roller shutter is a multi-pore type PVC anti-fouling curtain.

[0014] In the above technical solution, preferably, the head end of the anti-fouling roller shutter is equipped with two metal hanging rings, and the counterweight is equipped with two anti-detachment hooks, and the hanging rings can be fastened into the anti-detachment hooks above the counterweight.

[0015] The installation and retrieval of traditional anti-fouling screens or curtains are often quite cumbersome, especially in harsh aquatic environments where the construction is difficult and complex. This new anti-fouling screen allows a PVC anti-fouling roller shutter to be rolled up on a pre-designed torsion spring mechanism. During installation, the hanging ring at one end of the roller shutter can be pulled and hooked onto the anti-detachment hook above a concrete counterweight. Then, lowering the concrete counterweight completes the installation of one anti-fouling screen unit. After the anti-fouling work is completed, the hanging ring can be released, and the PVC anti-fouling roller shutter will automatically retract and roll back onto the torsion bar due to the rebound of the torsion spring mechanism, making it very convenient and quick.

[0016] This facility is a roll-up anti-fouling screen that is easy to install and recycle, especially in terms of facility recycling. It can effectively control the spread of mud and sand and prevent environmental pollution during water-related construction. It improves some of the shortcomings of existing anti-fouling screens used in water-related construction and greatly enhances the efficiency of anti-fouling screen installation and recycling during water-related construction operations such as dredging and reclamation.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are:

[0018] First, in order to facilitate the construction and layout of the anti-fouling screen, this utility model adopts a design where the anti-fouling roller shutter is rolled on a torsion spring mechanism. When the anti-fouling screen is laid out, the hanging ring at the head end of the anti-fouling roller shutter is pulled, which drives the torsion rod to rotate and tighten the spring. When the anti-fouling screen is retracted and disassembled, the hanging ring at the head end of the anti-fouling roller shutter is released. At this time, due to the rebound of the spring, the torsion rod is reversed, causing the anti-fouling roller shutter to automatically retract onto the torsion rod, making the construction more automatic and efficient.

[0019] Secondly, the design of multiple protective slots in this utility model not only ensures that the outer end of the spring can be locked, but also ensures that when the torque applied due to the continuous rotation of the torsion bar increases and exceeds the limit of the spring, the outer end of the spring will slide to the next protective slot, thus protecting the spring from damage.

[0020] Third, in order to ensure the stability of the anti-fouling screen during operation and prevent it from being greatly affected by factors such as wind, waves and water flow, this utility model adopts a hanging ring at the head end of the anti-fouling roller shutter, which is connected to the anti-detachment hook on the concrete counterweight block. This not only ensures stability and eliminates concerns about detachment, but also greatly protects the anti-fouling range of the anti-fouling roller shutter underwater, reducing the spread of pollution.

[0021] Fourth, the anti-fouling element of this utility model uses multi-pore PVC anti-fouling curtain fabric, which is more durable than the traditional non-woven geotextile fabric. Its firmness is also more suitable for use as a roller blind rolled up on a torsion rod, so there is no need to worry about easy damage leading to frequent replacement. It is more economical and practical. Attached Figure Description

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 7 As shown, a roller shutter-type anti-pollution screen for water-related construction includes an anti-pollution roller shutter 3 for restricting suspended sediment and garbage and preventing pollution spread. The densely distributed filter holes on the anti-pollution roller shutter 3 can greatly reduce the impact and pollution on the surrounding water area. It also includes a torsion spring mechanism 2, a float 1, and a counterweight 6. The torsion spring mechanism 2 is mainly responsible for realizing the automatic retraction function of the anti-pollution roller shutter 3 on the anti-pollution screen. It includes a torsion rod 2-1, a spring 2-2, and a spring box 2-4. The anti-pollution roller shutter 3 is rolled up on the torsion rod 2-1. The spring 2-2 is set in the spring box 2-4. A spring is inserted into the left and right ends of the torsion rod 2-1. The spring box 2-4 is connected to the inner end of the spring 2-2 inside it. The outer end of the spring 2-2 is curled and inserted into the protective slot 2-5 inside the spring box 2-4. When the torsion bar 2-1 rotates, it will cause the spring 2-2 to tighten. Similarly, when the spring 2-2 rebounds, it will cause the torsion bar 2-1 to reverse. A float 1 is tied to the top of the left and right ends of the torsion bar 2-1. The float 1 is tied to the two ends of the torsion bar 2-1 to ensure that the anti-fouling screen has sufficient buoyancy so that its anti-fouling working range can extend to near the water surface. The head end of the anti-fouling roller shutter 3 is detachably connected to the counterweight 6 to ensure the stability of the anti-fouling screen.

[0037] In a preferred embodiment, the anti-fouling roller shutter 3 is a multi-pore type PVC anti-fouling curtain. The main anti-fouling material of the roller shutter-type anti-fouling screen used for water-related construction is a multi-pore type PVC anti-fouling curtain, which is rolled onto the torsion rod 2-1 on the torsion spring mechanism 2 to form the PVC anti-fouling roller shutter 3, which is economical and practical.

[0038] In a preferred embodiment, at least two protective slots 2-5 are provided inside the spring box 2-4 along the circumferential direction, so that when the load on the spring 2-2 is too large and exceeds the limit, the outer end of the spring 2-2 will slide down into another protective slot 2-5 as it deforms. This reciprocating motion can protect the spring 2-2 from structural damage.

[0039] As a preferred implementation method, such as Figure 4 As shown, the anti-fouling screen has a torsion spring mechanism 2, the middle component of which is a torsion bar 2-1. The two ends of the torsion bar 2-1 are disc surfaces. The sides of the two discs of the torsion bar 2-1 are provided with slots formed by two retaining plates 2-3. The two ends of the torsion bar 2-1 are connected to spring boxes 2-4. The slots formed by the retaining plates 2-3 extend into the interior of the spring boxes 2-4. Each spring box 2-4 contains a spring 2-2. The inner end of the spring 2-2 is engaged in the slot formed by the retaining plates 2-3, and the outer end of the spring 2-2 is curled and engaged in the protective retaining groove 2-5. For example... Figure 6As shown, during actual installation, each pair of anti-fouling screens is bolted together with a flange-like spring box cover 7 to stabilize the spring box 2-4. The two ends of the torsion bar 2-1 extend into the spring box 2-4 to hold the spring spring 2-2. This ensures that the spring box 2-4 does not rotate along with the torsion bar 2-1. When the torsion bar 2-1 rotates, it will use the slot to drive the spring spring 2-2 to tighten. Similarly, when the spring spring 2-2 rebounds, it will also drive the torsion bar 2-1 to reverse.

[0040] In a preferred embodiment, the head end of the anti-fouling roller shutter 3 is equipped with two metal hanging rings 4 for connecting to the concrete counterweight block 6 to ensure the stability of the anti-fouling screen. The concrete counterweight block 6 is equipped with two anti-detachment hooks 5, connected by the hanging rings 4 snapping into the anti-detachment hooks 5 on the top of the concrete counterweight block 6. Two hanging rings 4 are sewn onto the edge of the head end of the PVC anti-fouling roller shutter 3 to connect to the anti-detachment hooks 5 on the concrete counterweight block 6, ensuring sufficient stability of the anti-fouling screen and reducing the impact of underwater currents and tides.

[0041] The working principle of this utility model's roller shutter-type anti-fouling screen is as follows:

[0042] When preparing to install this roller shutter-type anti-fouling screen, first roll the PVC anti-fouling roller shutter 3 onto the torsion bar 2-1 of the torsion spring mechanism 2, and tie the floats 1 to both ends of the torsion bar 2-1, so that the entire anti-fouling screen body is in a roll state; then begin the underwater deployment. After determining the position in the required working water area, fasten the two hanging rings 4 on the PVC anti-fouling roller shutter 3 into the anti-detachment hooks 5 on the corresponding concrete counterweights 6, and then sink the concrete counterweights 6 into the water. Due to gravity, the counterweights 6 will sink underwater, causing the anti-fouling roller shutter 3 to unfold underwater. As the anti-fouling roller shutter 3 unfolds, it will cause the torsion bar 2-1 to rotate, thereby tightening the springs 2-2 at both ends. If the water depth is too deep, causing the torsion bar 2-1 to rotate continuously and the load on the springs 2-2 to exceed the limit, the outer end of the springs 2-2 will slide down to another protective slot 2-5 as it deforms. This reciprocating motion can protect the springs 2-2 from structural damage.

[0043] When the construction is completed and the anti-fouling roller shutter 3 is to be recycled, simply remove the two hanging rings 4 on the PVC anti-fouling roller shutter 3 from the anti-detachment hooks 5 on the concrete counterweight block 6. The torsion spring mechanism 2 will lose the balance of tension, and the spring 2-2 will automatically rebound, thereby driving the torsion bar 2-1 to reverse, naturally rolling the anti-fouling roller shutter 3 back onto the torsion bar 2-1. Finally, the anti-fouling screen roller and the concrete counterweight block 6 can be recycled.

[0044] The design and construction method of this anti-fouling screen for water-related construction facilitates the laying and recycling of the screen, and it can be reused multiple times. In particular, in terms of recycling, it is more automated and efficient than existing traditional anti-fouling screens, which speeds up the construction progress and saves construction time and economic costs.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
