Description

Technical Field

[0001] This utility model relates to the field of traffic safety facilities technology, and in particular to a tunnel entrance gantry-type flexible interception device that integrates water curtain and sound and light warning. Background Technology

[0002] Tunnels, as an important part of highways and urban roads, are high-risk areas for traffic accidents due to the rapid changes in light and environment at their entrances. Currently, tunnel entrances are generally equipped with warning facilities such as traffic signs and traffic lights. However, in adverse weather conditions such as heavy fog, rain, and snow, or when drivers are fatigued, the effectiveness of these conventional visual warnings is greatly reduced and insufficient to generate adequate alertness.

[0003] To enhance the proactiveness and effectiveness of warnings, the industry has begun exploring more mandatory warning methods, such as water curtain warnings. As a flexible interception device, a water curtain not only creates a strong visual impact but also gently deters vehicles attempting to breach it. However, water curtain devices consume significant amounts of water; directly discharging this water would result in serious waste and fail to meet energy conservation and environmental protection requirements.

[0004] To address water waste, some solutions have attempted to incorporate water recycling systems. However, in practice, water recovered from the ground inevitably carries large amounts of sediment, leaves, and other impurities. If these impurities are not adequately filtered, they can quickly clog the high-pressure nozzles in the sprinkler assembly, leading to uneven water curtain formations or even system failure. Existing filtration devices are often simple in structure, lack sufficient filtration precision, or their filter screens are cumbersome to disassemble and clean, requiring specialized tools and lengthy operation, resulting in high maintenance costs and poor reliability.

[0005] Therefore, this utility model proposes a tunnel entrance gantry-type flexible interception device that integrates water curtain and sound and light warning to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing tunnel entrance warning devices, such as limited warning methods, lack of flexible interception means, serious waste of water resources, and inconvenient maintenance and cleaning of the filtration system leading to easy clogging of the nozzles, this utility model aims to provide a tunnel entrance gantry-type flexible interception device with an improved structure that can effectively solve the above problems by integrating water curtain and sound and light warning.

The heating rod is used to heat the water in the water tank in a low-temperature environment to prevent freezing.

[0012] Preferably, the heating assembly further includes a mounting plate fixedly connected to the outside of the heating rod. The mounting plate is threadedly connected to the top of the water tank by a second screw. This detachable threaded connection facilitates the installation and removal of the heating rod.

[0013] Preferably, a sealing cover is rotatably connected to the top of the water tank. The sealing cover is used to cover the circular groove opened in the water tank for the heating rod after the heating rod is removed, so as to prevent debris from entering the water tank.

[0014] Preferably, as a specific embodiment, a sealing protrusion is fixedly connected to the bottom outer side of the sealing cover, and the size of the sealing protrusion matches the circular groove to enhance the sealing performance between the sealing cover and the circular groove.

[0015] Preferably, the nozzle assembly consists of multiple high-pressure nozzles, and the nozzles of the high-pressure nozzles are all vertically downward, so as to form a stable and uniformly covered water curtain, achieving a good warning and flexible interception effect.

[0016] Preferably, the surface of the collection box is provided with multiple drainage holes for quickly collecting water droplets, reducing surface runoff, and improving water circulation efficiency.

[0017] Preferably, the top of the water tank is also fixedly connected to a water inlet pipe for daily water replenishment of the water tank.

[0029] like Figure 2 and Figure 3 As shown, to facilitate cleaning the filter screen, the recycling assembly 3 also includes a handle 306, which is fixedly connected to the top of the coarse filter screen 304 and the fine filter screen 305 for lifting the filter screen. The recycling assembly 3 also includes an insert 307 that passes through the handle 306. The recycling assembly 3 also includes a first screw 308, which is threaded to the top of the filter box 302 and is used to lock the insert 307, thereby fixing the coarse filter screen 304 and the fine filter screen 305 inside the filter box 302.

[0030] The tunnel entrance gantry-type flexible interception device integrating water curtain and sound and light warning also includes a heating component 8, and the heating component 8 and the aforementioned water tank 6 form a specific detachable installation and sealing fit relationship.

[0031] Please refer to the following carefully. Figure 1 and Figure 5 The structure of the heating component 8 will be described in detail below: The heating assembly 8 includes a heating rod 801 for heating the water inside the water tank 6. The heating assembly 8 also includes a mounting plate 802, which is fixedly connected to the outside of the heating rod 801. The mounting plate 802 is threadedly connected to the top of the water tank 6 by a second screw 803, thereby allowing the heating rod 801 to be detachably installed inside the water tank 6.

[0032] At the same time, a circular groove is opened on the top of the water tank 6 for the heating rod 801, and a sealing cover 804 is rotatably connected to the top of the water tank 6.

[0033] During seasons when heating is required, the heating rod 801 is installed in the circular groove of the water tank 6 via the mounting plate 802 and the second screw 803 to heat the water; during seasons when heating is not required, the second screw 803 can be loosened and removed, and the heating rod 801 and the mounting plate 802 can be disassembled together. At this time, the rotatably connected sealing cover 804 is flipped over and placed on the circular groove.

[0034] To ensure a tight seal, a sealing protrusion 805 is fixedly connected to the outer bottom of the sealing cover 804, and the sealing protrusion 805 is pressed against the inner edge of the circular groove.

[0035] The detachable structure of the heating rod 801 and the cooperation of the sealing cover 804 ensure that the device can prevent the water curtain from freezing in winter by heating, and can effectively seal the water tank 6 after removing the heating rod 801 in other seasons to prevent external dust and other contaminants from entering and polluting the water resources.

[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 4 In order to improve the warning effect and interception force of the water curtain, the nozzle group 2 is composed of multiple high-pressure nozzles, and the nozzles of the high-pressure nozzles are all vertically downward. As another preferred embodiment, please refer to Figure 3 To facilitate the rapid entry of water into the recycling system, the surface of the collection box 301 is provided with multiple drainage holes; As another preferred embodiment, please refer to Figure 1 In order to facilitate the replenishment of water to the water tank 6, a water inlet pipe 7 is also fixedly connected to the top of the water tank 6.

[0037] The working principle of this utility model's integrated water curtain and audible / visual warning tunnel entrance gantry-type flexible interception device is as follows: In case of an emergency, the second water pump 5 is activated, the flashlight 4 illuminates, and the audible warning device is activated to emit a warning sound. The second water pump 5 draws water from the water tank 6 and delivers the water to the nozzle assembly 2 installed on the top of the gantry 1. The nozzle assembly 2 consists of multiple high-pressure nozzles, all of which are vertically downward. At this time, the water jets sprayed by the nozzle assembly 2 form a water curtain, thereby achieving flexible interception and visual warning.

[0038] During the water curtain spraying process, the falling water flows into the collection box 301 through multiple drainage holes on its surface; the water then flows into the filter box 302 through a pipe, and flows through the coarse filter screen 304 and the fine filter screen 305 in sequence to achieve filtration and purification; at this time, the first water pump 303 is started, and the first water pump 303 draws out the clean water inside the filter box 302 and transports it to the top of the water tank 6 through a pipe to complete the recycling of water resources; when water needs to be replenished, it can be replenished through the water inlet pipe 7 fixedly connected to the top of the water tank 6.

[0039] When the coarse filter 304 and the fine filter 305 need to be cleaned, the maintenance personnel should first loosen and remove the first screw 308 threaded onto the top of the filter box 302; after removing the first screw 308, the insert 307 passing through the handle 306 can be pulled out. At this time, the locking of the coarse filter 304 and the fine filter 305 is released. By holding the handle 306 fixed to the top of the filter, the two can be pulled out for cleaning.

[0040] In low-temperature winter conditions, the heating rod 801 installed inside the water tank 6 is activated to heat the water in the water tank 6 and prevent the water curtain from freezing. In other seasons, the second screw 803 can be loosened and removed to disassemble the heating rod 801, which is fixed to the mounting plate 802. After disassembly, the sealing cover 804, which is rotatably connected to the top of the water tank 6, is flipped over to cover the circular groove opened for the heating rod 801. The sealing protrusion 805 on the outer bottom of the sealing cover 804 ensures a tight seal and prevents dust from entering.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
