A drainage wellhead anti-fall device

Abstract

This utility model discloses a drainage wellhead anti-fall device, including an anti-fall mounting circular plate. An anti-fall mounting component is connected to one side of the anti-fall mounting circular plate, and a warning power supply mounting component is provided on one side of the anti-fall mounting component. A warning mounting component is also provided on one side of the warning power supply mounting component. This utility model improves upon the prior art. In practical use, the anti-fall mounting component not only prevents the drainage wellhead from falling but also facilitates the cleaning of impurities. It solves the problem that most existing anti-fall structures are fixed installations, and after long-term use, especially in the rainy season or in sewage wells, the surface of the filter screen or grating is easily covered and blocked by leaves, silt, garbage and other impurities. This not only seriously hinders the normal drainage function and causes water accumulation on the road, but also greatly increases the difficulty and cost of maintenance.

Description

Technical Field

[0001] This utility model relates to the field of drainage wellhead anti-fall device, specifically to a drainage wellhead anti-fall device. Background Technology

[0002] Urban drainage systems are crucial infrastructure. If manholes (such as storm drains and sewage drains) are left open due to missing, damaged, or displaced covers, they can easily cause pedestrians or vehicles to fall in, endangering public safety. Therefore, fall protection nets or gratings are often installed below the manholes as a secondary safety measure.

[0003] However, most existing fall protection structures of this type are fixed installations. After long-term use, especially during the rainy season or in sewage wells, their filter screens or grates are easily covered and clogged by leaves, silt, garbage, and other impurities. This not only seriously hinders normal drainage function, leading to water accumulation on the road, but also significantly increases maintenance difficulty and costs. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a drainage wellhead anti-fall device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A fall prevention device for a drainage well opening includes a fall prevention mounting circular plate, a fall prevention mounting component connected to one side of the fall prevention mounting circular plate, a warning power supply mounting component provided on one side of the fall prevention mounting component, and a warning mounting component provided on one side of the warning power supply mounting component.

[0007] To achieve the purpose of fall protection installation, the fall protection installation component includes a fall protection cage frame, which is connected to a fall protection installation circular plate. A hollow connecting circular plate is connected below the fall protection cage frame, and a wellhead clamping plate is connected below the hollow connecting circular plate. An impurity filter screen is installed inside the fall protection cage frame. Rod connecting plates are connected around the fall protection installation circular plate and the hollow connecting circular plate. A sliding rod is connected between the rod connecting plates. A cleaning installation frame is slidably fitted around the sliding rod, and a cleaning scraper is connected around the cleaning installation frame.

[0008] Furthermore, a pull handle is attached to one side of the cleaning mounting bracket.

[0009] Furthermore, in order to achieve the function of warning power supply installation, the warning power supply installation component includes a power supply support column, a power supply installation housing connected above the power supply support column, a storage battery installed inside the power supply installation housing, and a controller located on one side of the storage battery.

[0010] Furthermore, the battery is electrically connected to the controller.

[0011] Furthermore, in order to achieve the purpose of warning installation, the warning installation component includes a warning support rod, one end of which is connected to the power supply installation housing, and the end of the warning support rod away from the power supply installation housing is connected to a warning light. A light sensor is installed on the periphery of the power supply installation housing.

[0012] Furthermore, the light sensor and warning lights are electrically connected to the controller.

[0013] Furthermore, a support and reinforcement frame is connected to the periphery of the warning support rod, and the support and reinforcement frame is connected to the power supply installation housing.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) This utility model has made improvements to the existing technology. In actual use, the anti-fall installation component can prevent the drainage well from falling while also facilitating the cleaning of impurities. This solves the problem that most of the existing anti-fall structures are fixed installations. After long-term use, especially in the rainy season or in sewage wells, the surface of the filter screen or grid is easily covered and blocked by leaves, silt, garbage and other impurities. This not only seriously hinders the normal drainage function and causes water accumulation on the road, but also greatly increases the difficulty and cost of maintenance.

[0016] (2) In actual use, a storage battery that provides electrical energy is installed inside the power supply housing. Adjacent to the battery, a controller is installed to handle the logic control of the entire warning system. The output terminal of the battery is electrically connected to the power input terminal of the controller via wires to ensure that the controller receives continuous and stable operating power.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a drainage wellhead anti-fall device is provided, including an anti-fall mounting circular plate 1, an anti-fall mounting component 2 connected to one side of the anti-fall mounting circular plate 1, a warning power supply mounting component 3 provided on one side of the anti-fall mounting component 2, and a warning mounting component 4 provided on one side of the warning power supply mounting component 3.

[0026] like Figure 1-4 As shown, according to an embodiment of the present invention, the anti-fall device for drainage well opening includes an anti-fall cage frame 201, which is connected to the anti-fall installation circular plate 1. A hollow connecting circular plate 202 is connected below the anti-fall cage frame 201, and a well opening clamping plate 203 is connected below the hollow connecting circular plate 202. An impurity filter screen 204 is installed inside the anti-fall cage frame 201. A rod connecting plate 205 is connected around the anti-fall installation circular plate 1 and the hollow connecting circular plate 202. A sliding rod 206 is connected between the rod connecting plates 205. A cleaning installation frame 207 is slidably fitted around the sliding rod 206. A cleaning scraper plate 208 is connected around the cleaning installation frame 207, and a pull handle 5 is connected to one side of the cleaning installation frame 207.

[0027] Through the above technical solution, the core anti-fall structure of this drainage wellhead anti-fall device consists of an anti-fall mounting circular plate 1 and its connected anti-fall mounting assembly 2. The anti-fall mounting assembly 2 mainly includes a vertically extending anti-fall cage frame 201, the top of which is fixedly connected to the bottom of the anti-fall mounting circular plate 1. The bottom of the anti-fall cage frame 201 is firmly connected to the wellhead locking plate 203 through a hollow connecting circular plate 202, which is used to securely lock the entire device onto the drainage wellhead. Inside the anti-fall cage frame 201, a debris filter screen 204 is installed, the main function of which is to intercept larger debris or personnel that may fall from the wellhead, while allowing water to flow through. To facilitate maintenance of the surface of the debris filter screen 204, multiple rod connecting plates 205 are connected around the periphery of the anti-fall mounting circular plate 1 and the hollow connecting circular plate 202. Sliding rods 206 are horizontally installed between these rod connecting plates 205. A ring-shaped cleaning mounting bracket 207 is slidably fitted around the sliding rod 206. A cleaning scraper 208 is fixedly connected to the outer side of the cleaning mounting bracket 207, and the inner edge of the cleaning scraper 208 contacts the outer surface of the impurity filter screen 204. By manually pulling the pull handle 5 fixed to one side of the cleaning mounting bracket 207, the cleaning mounting bracket 207 can be moved up and down along the sliding rod 206, thereby driving the cleaning scraper 208 to scrape away the dirt and blockages attached to the outer surface of the impurity filter screen 204, keeping the filter screen unobstructed.

[0028] like Figure 1-4 As shown, according to the embodiment of the present utility model, the drainage well anti-fall device includes a warning power supply installation component 3, which includes a power supply support column 301. A power supply installation housing 302 is connected above the power supply support column 301. A storage battery 303 is installed inside the power supply installation housing 302. A controller 304 is provided on one side of the storage battery 303. The storage battery 303 is electrically connected to the controller 304.

[0029] Through the above technical solution, the intelligent warning function of the device relies on the warning power supply mounting component 3. This component is located on one side of the fall arrest mounting component 2, and its main body is a power supply support column 301, which is stably erected on the ground or base. The top of the power supply support column 301 is connected to the power supply mounting housing 302, forming a protective space. Inside the power supply mounting housing 302, a battery 303 that provides power is installed. Adjacent to the battery 303, a controller 304 is set up, which is responsible for the logic control of the entire warning system. The output terminal of the battery 303 is electrically connected to the power input terminal of the controller 304 through wires to ensure that the controller 304 receives continuous and stable operating power.

[0030] like Figure 1-4As shown, according to an embodiment of the present invention, the drainage wellhead anti-fall device includes a warning installation component 4 comprising a warning support rod 401. One end of the warning support rod 401 is connected to the power supply installation housing 302. A warning light 402 is connected to the end of the warning support rod 401 away from the power supply installation housing 302. A light sensor 403 is installed around the power supply installation housing 302. The light sensor 403 and the warning light 402 are electrically connected to the controller 304. A support reinforcement frame 6 is connected around the warning support rod 401 and is connected to the power supply installation housing 302.

[0031] Through the above technical solution, the warning installation component 4 is set on one side of the warning power supply installation component 3 to realize environmental perception and active warning. One end of the warning support rod 401 is connected to the upper part or side of the power supply installation housing 302, and the other end extends upward or outward and is connected to the warning light 402, such as an LED warning light. In order to enhance the stability of the warning support rod 401, a support reinforcement frame 6 is also connected to the periphery of the warning support rod 401. The other end of the support reinforcement frame 6 is also connected back to the power supply installation housing 302 to form a triangular support structure. A light sensor 403 is installed on the periphery of the power supply installation housing 302 to detect the ambient light intensity in real time. The signal output terminal of the light sensor 403 and the power control terminal of the warning light 402 are electrically connected to the controller 304. Its working principle is as follows: the light sensor 403 continuously monitors the ambient light brightness and transmits the signal to the controller 304. The controller 304 has preset logic, such as automatically controlling the circuit to switch on or off when the ambient light is below a certain threshold, which determines that it is night or there is insufficient light. When preset conditions are met, such as darkness, the controller 304 activates the circuit of the warning light 402, causing it to illuminate and clearly warn pedestrians and vehicles of the location of the manhole, preventing falls. When ambient light is bright enough, such as during the day, the controller 304 disconnects the circuit of the warning light 402 to conserve power for the battery 303. The battery 303 provides the necessary power for the entire warning system, including the controller 304, the light sensor 403, and the warning light 402.
