Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage equipment, and in particular to a temporary protective support frame for rainwater grates. Background Technology
[0002] Urban flooding and the risk of flooding pose significant threats to urban safety during the flood season. A major reason for urban flooding during heavy rainfall is that fallen leaves are washed onto storm drains and cover the drain grates before the rain falls, preventing rainwater from being collected in the main storm drain and causing it to accumulate on the road surface. Due to the large number of storm drain grates, it is not feasible to manually clean the fallen leaves covering them one by one during heavy rainfall.
[0003] The current solution is to open the storm drain grates in advance to allow fallen leaves to be washed into the main storm drain. However, without safety precautions, this could easily lead to road accidents. Safety cones and guardrails are placed at the open storm drain grates as warning measures. However, both safety cones and guardrails have drawbacks: safety cones are easily washed away by rainwater, or even washed into the storm drain inlets, clogging branch pipes and causing more serious flooding; and due to the large number of storm drain grates in the city, placing road construction safety guardrails is neither feasible nor convenient. Utility Model Content
[0004] In order to open the rain grate effectively, quickly and safely and accelerate the drainage effect, this application provides a temporary protective support frame for the rain grate.
[0005] This application provides a temporary protective support frame for rainwater grates, employing the following technical solution:
[0006] A temporary protective support frame for a rain grate includes a base plate, two side plates, and two plug-in plates; the plug-in plates are obliquely connected to the base plate, and the two plug-in plates are arranged parallel and spaced apart; a cavity for inserting a rain grate is formed between the two plug-in plates; the base plate is provided with support feet for supporting the rain grate, and the side plates are connected to both sides of the base plate and connected to the plug-in plates.
[0007] Optionally, the side plate includes an isosceles triangular plate and a curved plate, the curved plate being connected to the base of the isosceles triangular plate, and the curved plate being supported on the ground when the rain grate is inserted into the cavity.
[0008] Optionally, the apex of the isosceles triangular plate is provided with a rounded surface.
[0009] Optionally, the equilateral triangular plate has a through hole.
[0010] Optionally, the substrate is provided with a drainage groove for rainwater to flow through.
[0011] Optionally, the included angle between the substrate and the plug-in plate is 35-55°.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] This application sets the dimensions, positions, and angles of the plug-in plate, side plates, and base plate, connecting the three into a whole. A cavity is formed between the plug-in plate and the base plate, and the side plates on both sides further close the cavity, leaving only a notch for the rain grate to be inserted. After the rain grate is inserted into the cavity, it can be supported by the support frame of the base plate, thereby exposing the drain outlet and accelerating the drainage speed.

[0022] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0023] This application discloses a temporary protective support frame for a rain grate. The support frame is composed of five plates connected together, including a base plate 2, two side plates 3 and two plug-in plates 4. The two plug-in plates 4 are arranged in parallel and spaced apart. The plug-in plates 4 are inclinedly connected to the base plate 2, and the included angle between the plug-in plates 4 and the base plate 2 is 46.35°. A cavity for inserting a rain grate 1 is formed between the two plug-in plates 4.
[0024] The two side plates 3 are arranged parallel to each other on both sides of the base plate 2 and are connected to the plug-in plate 4. The side plate 3 includes an isosceles triangular plate 31 and a curved plate 32, with the curved plate 32 connected to the base of the isosceles triangular plate 31. The isosceles triangular plate 31 has through holes 33 to facilitate the overall transportation of the support frame. At the same time, the apex of the isosceles triangular plate 31 has rounded corners to avoid scratches. In addition, the device is yellow or orange and resembles a safety cone when viewed from the side, which can effectively warn vehicles and pedestrians and prevent pedestrians or vehicles from colliding with the opened rain grate. The plug-in plate 4 is connected from the base of the isosceles triangular plate 31 to one of the side edges. After the side plates 3 are connected, the cavity only has a notch for the rain grate 1 to be inserted.
[0025] When it is necessary to open the rain grate 1, insert the rain grate 1 into the cavity and support it with the support frame. At this time, the support feet 5 of the base plate 2 and the curved plate 32 of the side plate 3 are both supported on the ground. The contact surface between the two and the ground is L-shaped, which has a certain stability. If it is necessary to move the support frame, it can be moved through the through hole 33. The base plate 2 is provided with a drainage channel 21 for rainwater to flow. The accumulated water will be discharged into the rainwater main pipe through the drainage channel 21 and the surrounding gaps. Fallen leaves and other debris cannot accumulate on the rain grate 1.
[0026] This temporary protective support frame for rainwater grates is a completely new invention. Previously, municipal authorities used safety cones, shared bicycles, and safety railings as substitutes; no similar device for temporarily opening and protecting rainwater grates has been developed or used. In addition, this invention has the following significant advantages:
[0027] 1. Customized Design: This device is specifically designed for the temporary opening of rain grate. If different specifications of rain grate are required, the size, position and angle of the plug plate, side plate and base plate can be changed during the production process to produce different models of temporary protective support frames for rain grate.
[0028] 2. Strong support, wind and rain resistant: On the one hand, the device has a reasonable mechanical structure, which can stably support the rain grate; at the same time, it can maintain the specific angle of the rain grate opening to ensure that the corresponding drainage height is reached. On the other hand, the support feet 5 of the base plate 2 and the curved plate 32 of the side plate 3 are both supported on the ground, and the contact surface between the two and the ground is a stable L-shape, so it has strong wind and rain resistance and is not easily washed away or damaged by wind and rain.
[0029] 3. Safety and Aesthetics: On the one hand, this device provides effective shielding, and because it is yellow or orange, it resembles a safety cone when viewed from the side, effectively warning pedestrians and vehicles and preventing accidental collisions, significantly reducing the risk of road accidents. On the other hand, compared to other shielding methods, this device is not only more practical but also neater and more aesthetically pleasing, creating a pleasant atmosphere and becoming a scenic feature of the city on rainy days.
[0030] 4. Easy to install and transport: On the one hand, the structure of this device is simple and clear, meeting the designer's goal of "being able to use it at a glance." Users can easily understand it without special training, and its operation is simple, enabling rapid deployment, saving time and effort, and improving efficiency. On the other hand, this device is made of ABS material, which is both sturdy and lightweight. Compared to safety barriers and shared bicycles, using this device greatly reduces the difficulty of transport for municipal personnel.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
