Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, and in particular relates to a road construction fence. Background Technology

[0002] To ensure the safety and comfort of people's daily travel, urban road construction is of paramount importance. During the construction of urban roads, it is necessary to separate the roads with construction fences so as not to affect the normal use of other roads.

[0003] The utility model with announcement number CN221957350U specifically discloses a road construction fence. It uses a filter screen to filter dust in the air to prevent excessive dust leakage. Then, the workers connect the transmission pipes to the external water supply pipes. When water is supplied through multiple transmission pipes, it will be transmitted to multiple water nozzles. The multiple water nozzles will intercept the dust in the air, greatly reducing air pollution around the construction site. At the same time, it is also more convenient to install and dismantle the fence body.

[0004] In actual use, the fence itself has no protective structure. Accidental contact by passing vehicles or moving objects can easily cause deformation or damage to the fence, thereby affecting its service life and increasing the construction cost. Utility Model Content

[0005] The purpose of this utility model is to provide a road construction fence. The fence designed in this application has a protective structure that can buffer the impact of external objects, preventing the collision force from directly acting on the fence body and causing damage to the fence body. At the same time, the reflective strips fixed on its surface can warn passing pedestrians and vehicles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a road construction fence, comprising a base, a connecting shaft rotatably connected to the upper end of the base, and a lower horizontal plate rotatably connected to the upper end of the connecting shaft, an inner sleeve fixedly connected at equal intervals to the upper end of the lower horizontal plate, and a telescopic rod movably connected to the top of the inner sleeve, the bottom of the telescopic rod extending into the inner sleeve and movably connected to the inner sleeve, an upper horizontal plate fixedly connected to the top of the telescopic rod, at least three sets of rigid bladders fixedly distributed at equal intervals around the outer side of the inner sleeve, the rigid bladders being made of rubber, nozzles fixedly connected at equal intervals to the top of the upper horizontal plate, the upper and lower horizontal plates having a hollow internal structure design, and a second water inlet pipe fixedly connected to both ends of the upper horizontal plate, and a first water inlet pipe fixedly connected to both ends of the lower horizontal plate.

[0007] Preferably, the base and the connecting shaft have an internal hollow structure design, and the base is connected to the lower horizontal plate through the connecting shaft.

[0008] Preferably, a valve is fixed to the outer surface of the base near the lower side.

[0009] Preferably, the inner sleeve has a connecting hole on both the upper and lower sides of its outer surface, and the inner sleeve communicates with the rigid bladder through the connecting hole.

[0010] Preferably, a piston is fixedly connected to one end of the telescopic rod located inside the inner sleeve. The piston is made of rubber and designed to fit snugly against the inner wall of the inner sleeve.

[0011] Preferably, the bottom of the inner sleeve is provided with a second connecting hole, and the inner sleeve is connected to the lower horizontal plate through the second connecting hole.

[0012] Preferably, the nozzle is connected to the interior of the upper horizontal plate, and a reflective strip is fixed to the outside of the rigid capsule.

[0013] In summary, compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The fence designed in this application has a protective structure that can buffer the impact of external objects, preventing the impact force from directly acting on the fence body and causing damage to the fence body.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A road construction fence includes a base 1, with a connecting shaft 4 rotatably connected to the upper end of the base 1, and a lower horizontal plate 2 rotatably connected to the upper end of the connecting shaft 4. An inner sleeve 9 is fixedly connected at equal intervals to the upper end of the lower horizontal plate 2, and a telescopic rod 5 is movably connected to the top of the inner sleeve 9. The bottom of the telescopic rod 5 extends into the inner sleeve 9 and is movably connected to the inner sleeve 9. An upper horizontal plate 6 is fixedly connected to the top of the telescopic rod 5. At least three sets of rigid bladders 10 are fixedly distributed at equal intervals around the outer side of the inner sleeve 9. The rigid bladders 10 are made of rubber. Spray nozzles 8 are fixedly connected at equal intervals to the top of the upper horizontal plate 6. The upper horizontal plate 6 and the lower horizontal plate 2 have a hollow internal structure design, and water inlet pipes 2 and 3 are fixedly connected to both ends of the upper horizontal plate 6.

[0026] Specifically, the base 1 and the connecting shaft 4 have a hollow internal structure design, and the base 1 is connected to the lower horizontal plate 2 through the connecting shaft 4. A valve is fixed on the outer surface of the base 1 near the lower side.

[0027] Specifically, the inner sleeve 9 has connecting holes 12 on both the upper and lower sides of its outer surface, and the inner sleeve 9 is connected to the rigid bladder 10 through the connecting holes 12.

[0028] Specifically, a piston 11 is fixedly connected to one end of the telescopic rod 5 located inside the inner sleeve 9. The piston 11 is made of rubber and designed to fit the inner wall of the inner sleeve 9. Under the action of water pressure, the piston 11 in the inner sleeve 9 is driven to move upward, which drives the telescopic rod 5 to extend out of the inner sleeve 9 and drives the upper horizontal plate 6 to move upward.

[0029] Specifically, the bottom of the inner sleeve 9 is provided with a second connection hole 13, and the inner sleeve 9 is connected to the lower horizontal plate 2 through the second connection hole 13. The nozzle 8 is internally connected to the upper horizontal plate 6. The rigid bladder 10 is fixed with a reflective strip. Water is injected through the water inlet pipe 3 and then injected into the upper horizontal plate 6, and then sprayed through the nozzle 8 to reduce dust from the surrounding construction site. The reflective strip can warn pedestrians and vehicles passing by.

[0030] Working principle:

[0031] During operation, this application connects to the water inlet pipe 3 at one end of the lower horizontal plate 2 via a water pipe. The other end of the water inlet pipe 3 is sealed with a fitting. The water pipe is connected to an external water pump. The water pump draws water and injects it into the lower horizontal plate 2 through the water pipe and the water inlet pipe 3. When multiple fence bodies are connected, the water inlet pipes 3 at adjacent ends of the lower horizontal plate 2 are connected with fittings, and the water inlet pipes 7 at adjacent ends of the upper horizontal plate 6 are also connected with fittings. External water is injected into the lower horizontal plate 2, and then the water inside the lower horizontal plate 2 flows into the hollow connecting shaft 4 and the base 1, thereby increasing the weight of the base 1 and lowering the overall center of gravity of the fence, reducing the chance of tipping over during subsequent use. After the base 1 is full of water, the water enters the inner sleeve 9 through the connecting hole 13. Then, the water enters the rigid bladder 10 through the connecting hole 12. The rigid bladder 10 expands when filled with water, forming a protective barrier on the outside of the inner sleeve 9. When the rigid bladder 10 is full of water, the piston 11 in the inner sleeve 9 is driven to move upward under the action of water pressure, which drives the telescopic rod 5 to extend out of the inner sleeve 9 and drives the upper horizontal plate 6 to move upward, thereby increasing the height of the fence and unfolding the fence as a whole until it is impossible to fill the fence with water. Then, the water inlet pipe 3 is closed by the external sealing part. Later, the user can also fill the upper horizontal plate 6 with water through the water inlet pipe 3 and spray it through the nozzle 8 to reduce the dust generated by construction in the surrounding area. Afterward, the water in the base 1, the inner sleeve 9 and the rigid bladder 10 can be discharged by opening the valve on the base.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
