Description

Technical Field

[0001] This utility model relates to the field of municipal landscaping facilities technology, specifically to a tree pit grate. Background Technology

[0002] Tree grates are a common urban landscaping facility, widely used in streets, parks, and squares. Their main function is to cover the soil around the roots of trees, protecting the root system, preventing soil erosion, beautifying the environment, and ensuring pedestrian safety.

[0003] For example, Chinese utility model patent CN220000210U discloses a combinable tree grate, relating to the field of landscaping technology. This tree grate is composed of multiple base plates spliced ​​together. Each base plate has a through groove penetrating two opposite surfaces, and a grid is installed within the through groove. An installation groove is provided on one side wall of each base plate, and a longitudinal slot is provided on the other side wall. A longitudinal insert is installed within the installation groove, and the extended longitudinal insert can be inserted into the longitudinal slot of another base plate. The combinable tree grate proposed by this utility model can be assembled and used according to the actual geographical shape.

[0004] The aforementioned technical solutions suffer from the following problems: Currently, the tree grates commonly used in the market, whether made of cast iron, composite materials, or stone, are primarily monolithic or composed of multiple rigidly connected panels. During installation, the entire grate or the assembled panels are directly placed on the tree pit's embankment to form a fixed cover. However, this traditional fixed installation structure has a significant and long-standing drawback: extremely poor maintainability and accessibility. During routine maintenance, fallen leaves, dead branches, and windblown debris accumulate inside the tree pit, requiring regular cleaning. Furthermore, pedestrians occasionally drop items into the tree pit. When cleaning or retrieval is needed, operators must completely disassemble and remove the entire or large sections of the grate. This process is not only tedious and labor-intensive, often requiring multiple people or mechanical tools, but the heavy grate is also prone to damaging curbs during repeated handling, significantly increasing maintenance time and labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a tree drain grate to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tree grate includes a base and multiple grate units. The multiple grate units are assembled by a detachable connection and form an opening in the middle for trees to pass through. The base is arranged around the opening of the tree pit. A connecting structure is fixedly installed on the inner wall of the base. The grate units are detachably connected to the base through the connecting structure.

[0008] Furthermore, the connection structure includes multiple mounting brackets, all of which are fixedly installed on the inner wall of the base, and a hinged bracket adapted to the mounting bracket is welded to the bottom of the grate unit.

[0009] Furthermore, the mounting bracket has a first through hole inside, and the hinge bracket has a second through hole inside. Bolts are installed inside the first and second through holes, and fastening nuts are threaded onto the outer side of the bolts. The bolts pass through the first and second through holes in sequence and are threaded onto the fastening nuts.

[0010] Furthermore, the bolt is an anti-theft bolt, and its head has an irregular structure, such as an inner pentagon, a plum blossom with a column, a triangular hole, or a structure that requires a special key to tighten. The fastening nut is an anti-theft nut that matches the anti-theft bolt.

[0011] Furthermore, the grate unit has multiple water-permeable holes inside, which are elongated and evenly distributed on the grate unit.

[0012] Furthermore, the grate units are detachably connected via a plug-in or overlapping structure.

[0013] Furthermore, the plug-in structure includes a protrusion on the side of one grate unit and a recess on the side of another adjacent grate unit that is adapted to the protrusion, wherein the protrusion and the recess engage in a snap-fit ​​connection.

[0014] Furthermore, the bottom of the grate unit is provided with a reinforcing structure.

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

[0016] 1. This utility model decomposes the traditional integral grate into multiple detachable grate units. This modular design makes each unit small in size and light in weight, greatly reducing the difficulty and cost of transportation and handling. During installation, no large hoisting equipment is required; manual handling and positioning are easy, significantly improving installation efficiency. Most importantly, when a part (such as a grate unit) is damaged or targeted maintenance of the area under a tree is needed, it is not necessary to replace or lift the entire grate; only the specific unit needs to be operated on, greatly reducing the cost and difficulty of later maintenance. A robust and reliable mechanical connection is formed by the cooperation between the mounting frame set on the inner wall of the base and the hinged frame at the bottom of the grate unit, secured with bolts and nuts. This structure can effectively withstand the loads of pedestrians and vehicles, ensuring safe use. At the same time, anti-theft fasteners requiring special tools for disassembly make the grate unit difficult to remove and steal with ordinary tools, effectively protecting public property. Furthermore, by combining different numbers of standard grate units, it can flexibly adapt to tree pits of different diameters and shapes, solving the problem of needing to customize the entire grate for a specific tree pit in the existing technology. It has strong versatility and reduces the complexity of procurement and inventory management.

[0017] 2. The grate units of this utility model are connected by a plug-in structure (such as the snap-fit ​​between protrusions and recesses) or an overlapping structure. This design not only ensures ease of assembly but also allows multiple units to form a cohesive and evenly stressed covering surface after assembly, preventing excessive displacement or misalignment between units and ensuring the smoothness of the road surface and the comfort and safety of pedestrians. Furthermore, the integrally formed reinforcing structure (such as reinforcing ribs) at the bottom of the unit further enhances its rigidity and load-bearing capacity, ensuring it is not easily deformed or damaged during use.

[0028] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with... Figures 1-4 The present invention will be further described below.

[0029] A tree pit grate includes a base 1 and multiple grate units 2. The multiple grate units 2 are assembled by a detachable connection and form an opening in the middle for trees to pass through. The base 1 is arranged around the opening of the tree pit. A connecting structure 3 is fixedly installed on the inner wall of the base 1. The grate units 2 are detachably connected to the base 1 through the connecting structure 3. Specifically, the connecting structure 3 allows the grate units 2 to be flipped individually, thereby facilitating workers to clean fallen leaves, dead branches, and garbage blown in by the wind or to retrieve fallen items inside the tree pit.

[0030] The connecting structure 3 includes multiple mounting brackets 301, all of which are fixedly installed on the inner wall of the base 1. A hinged bracket 302, adapted to the mounting bracket 301, is welded to the bottom of the grate unit 2. A first through hole 303 is formed inside the mounting bracket 301, and a second through hole 304 is formed inside the hinged bracket 302. Bolts 305 are installed inside the first and second through holes 303 and 304, respectively. A fastening nut 306 is threaded onto the outer side of the bolt 305. The bolt 305 passes through the first and second through holes 303 and is threaded onto the fastening nut 306. The bolt 305 is an anti-theft bolt. The part has an irregular structure, such as an inner pentagon, a plum blossom-shaped column, a triangular hole, or a structure that requires a special key to turn. The fastening nut 306 is an anti-theft nut that matches the anti-theft bolt. Specifically, the grate unit 2 is connected to the base 1 through the connecting structure 3. Under the action of the first through hole 303, the second through hole 304, the bolt 305, and the fastening nut 306, the grate unit 2 can be quickly disassembled and assembled, which makes it convenient for staff to unfold the grate unit 2. Moreover, the bolt 305 and the fastening nut 306, which require special tools to disassemble, make it difficult for the grate unit to be disassembled and stolen by ordinary tools, effectively protecting public property.

[0031] The grate unit 2 has multiple water-permeable holes 4 inside. The water-permeable holes 4 are elongated and evenly distributed on the grate unit 2. Specifically, the water-permeable holes 4 allow rainwater to enter the tree pit, making it easier for the trees to obtain water.

[0032] The grate units 2 are detachably connected through a plug-in or overlapping structure. The plug-in structure includes a protrusion 5 on the side of one grate unit 2 and a recess 6 on the side of another adjacent grate unit 2 that matches the protrusion 5. The protrusion 5 and the recess 6 are engaged. Specifically, the engagement of the grate units 2 through the protrusion 5 and the recess 6 not only ensures the ease of splicing, but also allows multiple units to form a well-integrated and evenly stressed covering surface after splicing. This avoids excessive displacement or misalignment between units, ensuring the smoothness of the road surface and the comfort and safety of pedestrians.

[0033] The bottom of the grate unit 2 is provided with a reinforcing structure 7. Specifically, the integrally formed reinforcing structure 7 (such as a reinforcing rib) at the bottom of the grate unit 2 further enhances the rigidity and load-bearing capacity of the unit, ensuring that it is not easily deformed or damaged during use.

[0034] Working principle and usage process of this utility model:

[0035] I. Normal Usage Status

[0036] In normal use, all grate units 2 interlock via the protrusions 5 and recesses 6 on their sides, forming a complete and flat cover in the center of the tree pit. Simultaneously, the hinge frame 302 at the bottom of each grate unit 2 is securely connected to the mounting bracket 301 fixed to the inner wall of the base 1 via bolts 305 and fastening nuts 306. At this point, the entire grate forms a stable whole, capable of withstanding the loads of pedestrians and vehicles, while the drainage holes 4 ensure normal rainwater infiltration.

[0037] II. Enabling Maintenance Status (Core Advantages Demonstrated)

[0038] Its convenience is fully demonstrated when it is necessary to clean fallen leaves, dead branches, trash, or pick up fallen items inside the tree pit:

[0039] Locating the target unit: The staff first determines the area that needs to be opened (such as the grate unit 2 above the pile of fallen leaves or the location where the item fell).

[0040] Disconnecting a single unit: Using a special tool compatible with the anti-theft bolts and nuts, simply loosen the fastening nut 306 corresponding to the target grate unit 2, and the bolt 305 can be pulled out, thereby detaching the unit from the base 1. No other units need to be disassembled, nor does the entire grate need to be moved.

[0041] Flip-opening unit: After the nut is loosened, the staff can lift the unit by hand and flip it upward around the hinge point, thus instantly opening a "maintenance window" leading to the inside of the tree pit.

[0042] Cleaning and retrieval operations: Through the open window, workers can easily clear debris inside using brooms, rakes, or other tools, or simply reach in and pick up fallen items. The entire process offers ample operating space and good visibility, greatly improving work efficiency.

[0043] Reset and tighten: After cleaning or picking up the items, gently lower the flipped-over grate unit 2 to restore it to a horizontal position. Then, reinsert the bolts 305 into the first through hole 303 and the second through hole 304, and tighten the fastening nut 306 to re-secure the unit and restore it to its normal use state.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
