[0002] The rain grate device is a common drainage device in the municipal road drainage system, which is used to drain the rainwater on the road into the drainage pipeline. The common rain grate device mainly includes a rain grate seat fixed above the rainwater well and a rain grate plate installed on the rain grate seat. Drainage through holes penetrating the upper and lower surfaces are formed on the rain grate plate. When a heavy rain occurs in the city, due to the limited size of the drainage through holes of the rain grate device, the drainage through holes are easily blocked by sundries such as fallen leaves, affecting the drainage efficiency of the rain grate device.

The flip-type rain grate device includes a rain grate seat, a rain grate plate hinged on the rain grate seat, and a driving member for driving the rain grate plate to flip. The driving member is usually an electric push rod. The tail end of the electric push rod is hinged on the inner wall of the drainage well, and the output rod of the electric push rod is hinged on the rain grate plate. When a heavy rain occurs in the city, the rain grate plate can be opened through the electric push rod, so that the rainwater can be discharged into the drainage pipeline through the opening after the rain grate plate is opened. This application provides another technical solution that can solve the above technical problems. Utility Model Content
[0004] In order to improve the problem that when a heavy rain occurs in the city, due to the limited size of the drainage through holes of the rain grate device, the drainage through holes are easily blocked by sundries such as fallen leaves, affecting the drainage efficiency of the rain grate device, this application provides a lifting rain grate device.
[0005] A lifting rain grate device provided by this application adopts the following technical solutions:
[0006] A lifting rain grate device includes a rain grate seat and a rain grate plate. The rain grate plate has drainage through holes penetrating the upper and lower surfaces. It further includes a mounting bracket fixedly connected to the rain grate seat, and an electric push rod installed on the mounting bracket and used to lift the rain grate plate. The telescopic rod of the electric push rod extends vertically upward; a lifting block is arranged at the top of the telescopic rod of the electric push rod, and a layout groove for arranging the lifting block is provided at the bottom of the rain grate plate.
[0007] By adopting the above technical solution, when heavy rain occurs in the city, the telescopic rod of the electric push rod can extend upward, thereby lifting the rain grate plate, so that the upper opening of the rain grate seat is opened, enabling rainwater to quickly enter the drainage pipe through the lifting rain grate device, which helps reduce the probability of waterlogging in the city during heavy rain weather. Moreover, the rain grate plate in the above lifting rain grate device can be removed from the rain grate seat, facilitating subsequent maintenance of components such as the electric push rod inside the lifting rain grate device.
[0008] Optionally, a placement groove for placing the rain grate plate is provided at the top of the rain grate seat.
[0009] By adopting the above technical solution, in the normal state of the above lifting rain grate device, the rain grate plate is supported by the rain grate seat, and the rain grate plate does not exert pressure on the telescopic rod of the electric push rod, resulting in a relatively small load on the telescopic rod of the electric push rod, which helps extend the service life of the electric push rod.
[0010] Optionally, the rain grate plate is in the shape of an inverted truncated cone, and the size of the placement groove is adapted to that of the rain grate plate.
[0011] By adopting the above technical solution, the shape of the rain grate plate is defined, and it is more convenient to place the inverted truncated cone-shaped rain grate plate into the corresponding placement groove.
[0012] Optionally, a load-bearing convex block protruding downward is provided in the middle area of the bottom surface of the rain grate plate, and the arrangement groove is opened on the bottom surface of the load-bearing block.
[0013] By adopting the above technical solution, the setting of the load-bearing convex block helps weaken the influence of the setting of the arrangement groove on the structural strength of the middle part of the rain grate plate, contributing to ensuring the structural strength of the middle part of the rain grate plate.
[0014] Optionally, the lifting block is in the shape of a truncated cone, and the size of the arrangement groove is adapted to that of the lifting block.
[0015] By adopting the above technical solution, the structure of the lifting block is defined. The truncated cone-shaped lifting block ensures that the rain grate plate does not rotate circumferentially when the rain grate plate is lifted, which helps the rain grate plate return smoothly into the rain grate seat during reset. Moreover, the truncated cone-shaped lifting block can be inserted into the arrangement groove more conveniently.
[0016] Optionally, the mounting bracket includes a mounting cross beam located below the rain grate seat and two mounting connecting rods respectively connected to both ends of the mounting cross beam; the mounting connecting rods are arranged obliquely and the top ends of the mounting connecting rods are connected to the top of the rain grate seat.
[0017] By adopting the above technical solution, the installation bracket has a structure with a smaller lower part and a larger upper part, which facilitates the installation of the rain grate seat with the installation bracket onto the drainage well, and reduces the probability of collision between the installation bracket and the inner wall of the drainage well during the installation process.
[0018] Optionally, a protective component is further arranged between the lifting block and the electric push rod. The protective component includes an upper fixing ring fixed to the bottom of the lifting block, a lower fixing ring fixed to the top of the housing of the electric push rod, and a telescopic bellows connecting the upper fixing ring and the lower fixing ring; the telescopic rod of the electric push rod is located inside the telescopic bellows.
[0019] Among them, a sealing structure is arranged in the area of the housing of the electric push rod where the telescopic rod extends. Since the lifting rain grate device is applied to the drainage system of municipal roads, during daily drainage, rainwater is likely to impact the top of the housing of the electric push rod and the telescopic rod of the electric push rod, and sediment in the rainwater is easily adsorbed on the top of the housing of the electric push rod and the telescopic rod of the electric push rod, which easily causes the sealing structure of the electric push rod to fail, thus affecting the service life of the electric push rod. Therefore, the setting of the above protective component can prevent rainwater from directly flushing on the top of the housing and the telescopic rod, thereby protecting the sealing structure of the electric push rod and helping to extend the service life of the electric push rod.
[0020] Optionally, a protective sleeve extending downward is sleeved outside the bearing bump. When the rain grate plate is installed on the rain grate seat, the bottom end of the protective sleeve abuts against the top of the housing of the electric push rod.
[0021] Since the occurrence of heavy rain is relatively rare in some areas, it is only necessary to protect the sealing structure of the electric high push rod during daily drainage. By adopting the above technical solution, when the rain grate plate is not lifted, the protective sleeve can protect the telescopic rod of the electric push rod, avoiding direct flushing of rainwater on the telescopic rod and the top of the electric push rod at this time, thereby helping to extend the service life of the electric push rod.
[0022] Optionally, a sealing flange for abutting against the top of the housing of the electric push rod is circumferentially arranged at the lower end of the protective sleeve, and the sealing flange is folded outward.
[0023] By adopting the above technical solution, when the rain grate plate is not lifted, the structural setting of the sealing flange makes the sealing effect between the lower end of the protective sleeve and the top of the housing of the electric push rod ideal.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] A lifting rain grate device, by setting an electric push rod for lifting the rain grate plate, makes the rain grate plate lifted during heavy rain, which helps to reduce the probability of urban waterlogging during heavy rain. And the telescopic rod of the electric push rod and the bottom of the rain grate plate are separately arranged, so that it is convenient to remove the rain grate plate from the rain grate seat, thus facilitating the maintenance of components such as the electric push rod;
[0026] By setting the rain grate plate into an inverted frustum shape and arranging an inverted frustum-shaped placement groove on the rain grate seat, it is convenient to install the rain grate plate onto the rain grate seat;
[0027] By setting a protective component or a protective sleeve to protect the sealing structure of the electric push rod, it helps to extend the service life of the electric push rod. Brief Description of the Drawings

The rain grate seat 1 is provided with a placement groove 11 at its top for placing the rain grate plate 2. Among them, the placement groove 11 is in the shape of an inverted truncated cone. Since the rain grate seat 1 is a square frame metal seat, the placement groove 11 is in the shape of an inverted frustum of a square pyramid.
[0036] Refer to Figure 1 , the rain grate plate 2 is a square metal plate structure, and the shape of the rain grate plate 2 is adapted to the shape of the placement groove 11, which is in the shape of an inverted frustum of a square pyramid. The rain grate plate 2 is provided with drainage through holes 21 for rainwater to flow through. In this embodiment, the drainage through holes 21 in the rain grate plate 2 are strip-shaped through holes and are arranged in two rows.
[0037] Refer to Figure 1 , the mounting bracket 3 includes a mounting cross beam 31 located below the rain grate seat 1 and two mounting connecting rods 32 respectively connected to both ends of the mounting cross beam 31. The top ends of the mounting connecting rods 32 are fixed to the bottom of the rain grate seat 1. In this embodiment, an upper mounting plate 321 is provided at the top of the mounting connecting rod 32. The upper mounting plate 321 fits against the bottom surface of the rain grate seat 1 and is fixed to the rain grate seat 1 by screws; a lower mounting plate 322 is provided at the bottom of the mounting connecting rod 32. The lower mounting plate 322 fits against the top surface of the mounting cross beam 31 and is fixed to the mounting cross beam 31 by screws. Among them, the length of the mounting cross beam 31 is less than the width of the rain grate plate 2, so that the mounting connecting rods 32 are arranged obliquely, making the entire mounting bracket 3 present a state of being larger at the top and smaller at the bottom.
[0038] Refer to Figure 1 , the electric push rod 4 is fixed to the middle of the top surface of the mounting cross beam 31 by screws. The telescopic rod of the electric push rod 4 extends upward. A lifting block 5 is installed at the top of the telescopic rod. The lifting block 5 is in the shape of a truncated cone as a whole. In this embodiment, the lifting block 5 is a frustum of a square pyramid. A bearing convex block 22 protruding downward is provided in the middle area of the bottom surface of the rain grate plate 2. A placement groove 23 for inserting the lifting block 5 is provided on the bottom surface of the bearing convex block 22. Among them, the size of the placement groove 23 is adapted to the lifting block 5, and the placement groove 23 is in the shape of a frustum of a square pyramid.

When the protective component 6 is installed between the lifting block 5 and the electric push rod 4, the telescopic rod of the electric push rod 4 is located inside the protective component 6.
[0040] Combined with Figure 1 and Figure 2 , the lifting rain grate device in the embodiment of the present application can cooperate with the liquid level sensor. The liquid level sensor is installed on the road in the area where the lifting rain grate device is located. When the liquid level sensor detects that the water depth on the road reaches a certain value, the liquid level sensor transmits a signal to the control system, and then the control system controls the electric push rod 4 of the lifting rain grate device, so that the telescopic rod of the electric push rod 4 rises, so that the lifting block 5 is inserted into the layout groove 23 of the rain grate plate 2, so that rainwater can directly drain into the rainwater well and the drainage pipeline through the opening of the rain grate seat 1. Embodiment
[0041] The lifting rain grate device in this embodiment is the same as the lifting rain grate device in Embodiment 1 in all other structures except that the protective component 6 is not provided and a protective sleeve 7 is provided.
