Description

Technical Field

[0001] This utility model belongs to the field of drainage component technology, and in particular relates to a rain grate with a warning function. Background Technology

[0002] A storm drain grate is a structure designed to drain water from road surfaces into drainage pipes. Currently, the most widely used storm drain grates have a flat upper grating surface. However, in practice, this type of grate is not effective at drainage, especially on sloping roads where water flow is rapid, causing water to quickly flow over the grate surface and reducing its drainage efficiency. A three-dimensional storm drain grate is much easier to drain. Most storm drain grates are installed on roads, and when there is severe flooding or the grate is blocked, it is easily opened by people to drain the water. Without a warning function, this poses a significant safety hazard to pedestrians and vehicles. This new type of storm drain grate has an arched surface, a three-dimensional structure that facilitates drainage, and it also activates a warning function when there is severe flooding or the grate is opened.

[0003] Patent document CN220247160U discloses an intelligent side ditch grate. When rainfall increases and water gradually accumulates on the ground, or when traffic needs to be blocked for maintenance or other purposes, the grate's control signal generator sends an operation signal to activate the lifting device. Driven by a motor and a crawling gear and rack, the grate moves upward, causing the baffle to move and lift. Simultaneously, warning lights on the baffle flash and emit a warning sound to alert vehicles and pedestrians on the road. This control method and structure are more complex, requiring an additional drive motor, increasing installation costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rain grate with a warning function.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a rain grate with a warning function, including a grille, a water tank, and a lighting assembly. The grille is connected to the water tank through a mounting frame, and the lighting assembly is disposed in the cavity of the water tank. The water tank is cylindrical with a cavity at its center, and a conductive component and a lighting compartment are disposed in the cavity.

[0007] Preferably, the lighting assembly includes a lamp and a float, the lamp is equipped with a switch, the float is equipped with a connecting rod, the lamp is mounted on a lamp compartment, a battery can be installed in the lamp compartment, and the lamp compartment is connected to a water tank.

[0008] Preferably, the float is annular, and the connecting rod is hinged to the lamp housing.

[0009] Preferably, the grating is provided with a baffle plate and a connecting block, the baffle plate is provided with a water inlet, and the connecting block is provided on one side of the grating.

[0010] Preferably, the grating is arched, and a plurality of skeletons and grating bars are provided on the grating. The baffle is connected to the skeleton, and the grating bars are connected to the skeleton.

[0011] Preferably, the conductive component includes a first conductive element, an elastic element, and a pin. One end of the first conductive element is connected to the elastic element, and one end of the pin is connected to the inner wall of the cavity through the elastic element and a sliding sleeve. The elastic element is electrically connected to the lamp assembly. A second conductive element is disposed on the pin, and the sliding sleeve is disposed on the inner wall of the cavity. The cavity is located inside the connecting block.

[0012] Preferably, the mounting frame includes a fixing ring and a limiting ring, the limiting ring being disposed on the fixing ring, and a connector being disposed on one side of the fixing ring and connected to the limiting ring.

[0013] Preferably, an inner ring is provided inside the limiting ring.

[0014] Preferably, a baffle is provided at the bottom of the water tank, the baffle is movably connected to the water tank, and a drain hole is provided on the baffle.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention, through the design of the lighting components, ensures that when the grate is submerged, rainwater enters the water tank. When the water volume in the tank exceeds its drainage capacity, a float rises, causing a connecting rod to contact a switch, triggering the lighting switch and illuminating the lamp. In the event of a submerged grate, maintenance personnel can quickly locate the grate by observing the warning light and open it or clear any obstructions to drain the water. The conductive component ensures that the lamp illuminates when the grate is opened, alerting pedestrians and serving a warning function.

[0017] The difference between this utility model's rain grate and the traditional rain grate is that the rain grate's grille has a round arch structure and the surface of the rain grate has a three-dimensional structure. When installed on a flat road surface, water can enter around the rain grate without easily getting clogged. When installed on a sloping road surface, water can more easily flow into the rain grate to achieve the purpose of drainage. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0027] Example:

[0028] like Figures 1 to 7 As shown, a rain grate with a warning function includes a grille 1, a water tank 2, and a light assembly 3. The grille 1 is connected to the water tank 2 via a mounting frame 4. The light assembly 3 is disposed in the cavity of the water tank 2. A cavity 21 is provided on one side of the grille 1, and a conductive component is disposed in the cavity 21.

[0029] The lighting assembly 3 includes a lamp 31 and a float 32. The lamp 31 is a waterproof LED warning light. The lamp 31 can be configured with an internal replaceable battery or an external power supply, depending on the actual situation. The light source of the lamp 31 illuminates its surroundings. The lamp 31 is mounted on a lamp housing 35, and the lamp 31 and lamp housing 35 are movably connected. A switch 33 is installed on the lamp housing 35. The float 32 has two connecting rods 34, one of which is hinged to the inner wall of the water tank, and the other connecting rod is connected to the switch 33 through the inner wall of the water tank. The lamp housing 35 is connected to the water tank 2, and a battery 36 is installed inside the lamp housing 35. The battery 36 is electrically connected to the lamp 31 through the switch 33. The light strip of the lamp 31 is circular and positioned below the water tank 2. The lamp housing 35 is located below the water baffle 5, preventing water from entering the lamp housing 35.

[0030] The float 32 is annular, and the connecting rod 34 is hinged to the lamp compartment 35. The connecting rod 34 is divided into two sections, which are hinged together to avoid the connecting rod 34 interfering with the movement of the float 32. The connecting rod 34 is connected to the inner wall of the water tank 2 with a waterproof ball and then extends to connect with the switch 33. When the water level in the water tank 2 rises, the float 32 rises, causing the connecting rod 34 to swing at the end near the switch 33. Then, pressing the switch 33 powers on the battery 36. When the water level drops, the float 32 falls, and the connecting rod 34 swings in the opposite direction at the end near the switch 33. Pressing the switch 33 powers off the battery 36.

[0031] The grating component 1 is provided with a baffle plate 5 and a connecting block 11. The baffle plate 5 is provided with a water inlet 51 through which external water enters. The connecting block 11 is located on one side of the grating component 1. The cavity 21 is the internal space of the connecting block 11.

[0032] The grating 1 is arched, which prevents water from flowing directly over its surface and thus reducing drainage efficiency. The grating 1 has several frames 13 and grating strips 12. The frames 13 are linear and connected to the outer ring of the grating, the grating strips 12, the baffle plate 5, and the water trough 2. The grating strips 12 are annular, and their diameter varies according to their position. The grating strips 12 are connected to the frames 13. The several frames 13 and grating strips 12 are arranged in an alternating pattern to form a mesh-like grating 1, facilitating drainage and preventing debris from entering the grate. The baffle plate 5 is arched, with the same curvature as the grating 1, preventing water from flowing directly onto the light fixture 31.

[0033] The conductive component includes a first conductive element 6, an elastic element 7, and a pin 8. One end of the first conductive element 6 is connected to the elastic element 7. One end of the pin 8 is connected to the inner wall of the cavity 21 through the elastic element 7 and the sliding sleeve 81, so that the pin 8 can move towards the sliding sleeve 81 when the inner wall of the connecting member 43 presses it. The elastic element 7 is electrically connected to the lamp assembly 3. A second conductive element 82 is provided on the pin 8. The second conductive element 82 is fixedly connected to the fixing member 83. The pin 8 and the second conductive element 82 are slidably connected. The fixing member 83 is located in the cavity 21. The sliding sleeve 81 is located on the inner wall of the cavity 21. Both the first conductive element 6 and the second conductive element 82 are provided with wires to electrically connect the lamp 31 and the battery 36. This circuit is connected in parallel with the circuit formed by the lamp 31, the switch 33, and the battery 36. When the first conductive element 6 and the second conductive element 82 are in contact, the battery 36 supplies power to the lamp 31, and the lamp 31 lights up. When the grille 1 is opened to allow for a larger flow of drainage, the connecting block 11 does not contact the connecting member 43. Under the action of the elastic member 7, the first conductive member 6 and the second conductive member 82 come into contact, and the light fixture 31 lights up to alert pedestrians that the grille 1 is open, thus preventing the grille 1 from being unseen due to being submerged in water and falling into the drainage well. When the grille 1 is closed, the inner wall of the connecting member 43 squeezes the ejector pin 8 into the sliding sleeve 81, the first conductive member 6 and the second conductive member 82 do not come into contact, and the light fixture 31 goes out.

[0034] The mounting frame 4 includes a fixing ring 41 and a limiting ring 42. The limiting ring 42 is mounted on the fixing ring 41. A connecting piece 43 with a frame structure is mounted on the fixing ring 41 and connected to the limiting ring 42. The height of the limiting ring 42 is greater than the height of the fixing ring 41. The grille 1 is fitted onto the limiting ring 42 to stabilize the grille 1. The mounting frame 4 is connected to the ground, and the connecting piece 43 is hinged to the connecting block 11. This design allows the grille 1 to be opened but not directly removed to prevent theft.

[0035] An inner ring 44 is provided inside the limiting ring 42, and the bottom of the grille 1 can be placed on the inner ring 44.

[0036] The bottom of the water tank 2 is threadedly connected to a baffle 22. The baffle 22 can be removed to clean internal debris. The baffle 22 is provided with a drain hole. The flow rate of the drain hole on the baffle 22 is less than the flow rate of the inlet 51. When the water inlet of the water tank 2 is greater than the water outlet, the water level will rise.
