Description

Technical Field

[0001] This utility model relates to the field of construction site equipment technology, and in particular to a water-filled wind-resistant isolation fence. Background Technology

[0002] Retractable barriers play a vital role as commonly used temporary isolation facilities in various public places and engineering construction scenarios. However, current retractable barriers on the market have several limitations: The main limitations include fixed-base type: These barriers typically use solid plastic or metal bases, which, while offering some stability, are extremely inconvenient to handle and transport due to their weight, requiring significant manpower and resources. While relatively lightweight and easy to carry, this type of barrier lacks stability. When used outdoors, it is prone to tipping over in strong winds, failing to effectively guarantee the safety of the isolated area. In narrow passages, a tipped barrier can also obstruct passage, causing accidents and posing safety hazards. The counterweight type: This method increases stability by adding artificial counterweights such as stones, sandbags, or iron blocks, but the process is cumbersome. During installation, the counterweights need to be placed one by one, and during disassembly, they need to be collected and sorted one by one, which consumes a lot of time and energy. Moreover, the counterweights are easy to lose during use, which increases maintenance costs and management difficulty. When using manual counterweights, many stones are placed at the base of the fence, which is time-consuming, laborious, and unsightly. These traditional retractable barriers cannot achieve a good balance between easy handling and strong wind resistance, making it difficult to meet the needs of modern scenarios for efficient, safe, and convenient use of temporary isolation facilities.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-3 As shown, a water-filled windproof isolation fence includes several water-filled bases 1 that can be filled and drained. Each water-filled base 1 has a detachable column assembly 2 connected to its top. The column assemblies 2 are connected by a retractable spring device 3. The several water-filled bases 1 are interconnected via the spring device 3 to form a fence. Each water-filled base 1 has an inner and outer double layer, with reinforcing ribs 6 between the inner and outer layers. In this embodiment, the water-filled base uses a double-layer structure design, providing good durability and water storage capacity. The outer layer wall thickness can be selected as 3-5mm, the inner reinforcing rib thickness is 2-3mm, and the size of a single base can be selected as... With a length of 300-400mm, a width of 200-300mm, and a height of 150-200mm, this size design ensures sufficient water storage space to increase weight while facilitating handling and storage. After filling with water, based on the density of water (1kg / L), the weight of a single base is approximately 15-20kg, effectively improving the wind resistance of the fence. In this embodiment, a scale can be set on the outer surface of the base to indicate the water level. When in use, this application has a standard water inlet and outlet, which can be filled with water through a water pipe. To ensure that the base can withstand water pressure after filling and is not easily deformed, this application has reinforcing ribs between the outer and inner layers to strengthen the structure.

[0019] Preferably, the top of the water-filling base 1 is provided with a water inlet 4, and a threaded sealing cap 7 is threadedly connected to the water inlet 4. A quick drain valve 5 is installed on the water-filling base 1. In this embodiment, the water inlet 4 is set at the top of the water-filling base 1, and a threaded sealing cap 7 is provided on the water inlet 4 to seal the water inlet 4. Preferably, a T-shaped guide rail 8 is horizontally arranged on the top of the water-filling base 1, and a slot 9 that matches the T-shaped guide rail 8 is arranged on the bottom of the column assembly 2. This embodiment is a first embodiment in which the column assembly 2 and the T-shaped guide rail 8 are detachably connected. By providing a T-shaped guide rail 8 horizontally on the top of the water-filling base 1 and a matching slot 9 on the bottom of the column assembly 2, the column assembly 2 can be slidably inserted into the T-shaped guide rail 8 during use. In this embodiment, the connection between the water-filling base 1 and the column assembly 2 is detachable. In this embodiment, the T-shaped guide rail 8 and the slot 9 make disassembly easier, but conventional methods such as threaded connection can also be used. A threaded groove can be opened on the top of the water-filling base, and the column assembly 2 can be detachably connected by threaded engagement.

[0020] Preferably, the top of the water-filled base 1 is provided with a horizontal groove 10, and the bottom of the column assembly 2 is provided with a slider 11 that cooperates with the groove 10. The groove 10 and the slider 11 are detachably connected. This embodiment is a second embodiment in which the column assembly 2 and the T-shaped guide rail 8 are detachably connected. That is, a horizontal groove 10 is provided on the top of the water-filled base 1, and a slider 11 is provided on the bottom of the column assembly 2. The detachable connection is achieved by the cooperation of the slider 11 and the groove 10.

[0021] Preferably, the bottom of the water-filled base 1 is further provided with a support seat 12. The side of the support seat 12 has an inward groove, and the drain valve 5 is disposed in the groove. In this embodiment, the existing water-filled base 1 often places the drain outlet on the side of the base when waterproofing. This often results in water not being completely drained from the base. With long-term use, water accumulates inside the base, deteriorates, and corrodes the inner wall of the base. However, since the water-filled base 1 needs to be in contact with the ground when in use, a support seat 12 can be added to the bottom of the water-filled base 1. The height of the support seat 12 only needs to be higher than the drain valve 5. Therefore, the support seat 12 can be placed at the bottom of the water-filled base 1 to increase the drainage performance without affecting the overall structural weight. In this embodiment, a notched groove is provided on the support seat 12, and the drain valve 5 is disposed in the groove at the bottom of the water-filled base 1. The drain valve 5 is a prior art and a conventional manual ball valve can be selected.

[0022] Preferably, a plurality of base plates 13 are hinged to the outer periphery of the support base 12. In this embodiment, conventional windproof bases in the prior art have a counterweight base, in which a weight is mounted on the base to increase its weight. This embodiment takes into account the use in situations where water sources are scarce, therefore, a plurality of base plates 13 are hinged to the outer periphery of the support base 12. Figure 2 As shown, several outwardly rotating base plates 13 are hinged to the bottom of the support base 12. When the water source at the construction site is insufficient, heavy objects can be manually moved and pressed onto the base plates 13 at the construction site to provide a certain counterweight for temporary use to resist strong winds and increase the stability of the base without damaging the water-filled base 1.

[0023] Preferably, the post assembly 2 includes a metal rod 21, on which a coiling spring device 3 and a hanging ring 22 are installed. A webbing 31 is provided on the coiling spring device 3. In this embodiment, the post assembly 2 belongs to the conventional technical means in the field of fencing, that is, it includes a metal rod 21 and a coiling spring device 3 provided on the metal rod 21. The coiling spring device adopts a constant force spring design. After precise calculation and adjustment, the extension and retraction force is controlled to ≤5N, so that the user can easily operate when stretching and retracting the webbing without consuming too much strength (in this embodiment, the coiling spring device can be the "telescopic fence coil spring" in the prior art); the webbing material is made of high-strength polyester yarn, coated with PVC waterproof coating, the webbing width is 50mm, and the thickness is 1.5-2mm. This type of webbing not only has high strength and can withstand a certain amount of tension, but also has good waterproof performance, making it suitable for different usage environments and extending its service life. Warning signs: The webbing surface is printed with warnings such as "Stop, High Voltage Danger" and "No Entry" using professional printing technology, with a font height of not less than 50mm, ensuring clear visibility even from a distance and playing a good warning role. At the same time, the column assembly of this application can also be directly customized and purchased from existing technology column assemblies with telescopic isolation belts. In addition, the metal pole 21 in this embodiment is also provided with a hanging ring 22 that cooperates with the webbing 31, which can be used to hang the webbing 31 on other columns to form an isolation belt.

[0024] Preferably, the T-shaped guide rail is provided with a through hole, and the slot 9 is provided with a positioning hole 91 that matches the through hole. The positioning hole 91 can be fixed by bolts engaging with the through hole. In this embodiment, after the column assembly 2 is inserted into the water-filled base 1, it is horizontally locked by the positioning hole and the φ8mm bolt. When tightening the bolt, the torque needs to reach ≥8N・m to ensure a firm connection, withstand wind and external forces, and ensure the stability of the fence.

[0025] Preferably, the webbing 31 is woven from polyester yarn, and the surface of the webbing 31 is coated with a PVC waterproof coating.

[0026] Preferably, the water-filled base 1 is made of polyethylene.

[0027] The specific working method of this application is as follows: (I) Installation steps Water filling the base: Place the base stably on a flat surface where the fence will be installed, and open the water inlet cap. Connect a faucet or bucket and fill the water chamber with water. Observe the water level change through the water level observation window during the filling process. Stop filling when the water level reaches the maximum water level line. The filling time is approximately 40-60 seconds. Tighten the water inlet cap to ensure a good seal and prevent water leakage during use.

[0028] Column installation: Align the inverted T-shaped slot at the bottom of the column with the T-shaped guide rail at the top of the base, and push it horizontally along the guide rail until the positioning hole is aligned. Take out the matching M8 bolt, insert it into the positioning hole and tighten it. Use a torque wrench to tighten the bolt torque to ≥8 N・m to ensure a firm connection between the column and the base.

[0029] Fence Connection: Pull out the telescopic straps at the top of adjacent fence posts and accurately connect the metal hooks at the ends of the straps to the hanging rings on the other post. Adjust the webbing tension to ensure the webbing is taut, guaranteeing a tight connection between the fence posts and forming a stable isolation barrier.

[0030] (II) Demolition Steps Drainage procedure: Open the drain valve at the bottom of the base and wait for the water in the filling chamber to drain naturally, which takes about 20-30 seconds. After the water has drained, wipe the valve and the surface of the base dry with a clean cloth to remove any remaining water stains and keep the base dry.

[0031] Column disassembly: Use tools to loosen the fixing bolts connecting the column and the base. Pull the column horizontally along the T-shaped guide rail to separate the column from the base and store them separately.

[0032] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
