[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments.

[0021] In the description of the utility model, it needs to explain, the orientation or position relation of "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indication is based on the orientation or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and not indicating or implying that the indicated device or element must have a specific orientation, a specific orientation and operation, therefore, it cannot be understood as a limitation on the utility model.

[0022] A waterproof buried door opening device of intelligence and convenient to maintain, as Figures 1-4 shown, including device body 1, motor 2, transmission mechanism 3 is arranged in the device body 1 inside;The motor 2 is located in the area above the device body 1 shell on the maintenance window 4 and detachable maintenance cover plate 5 are set up, the detachable maintenance cover plate 5 is fixed around the maintenance window 4 through a plurality of screws, the maintenance window 4 and the detachable maintenance cover plate 5 between the sealing structure are provided with.

[0023] Specifically, the core maintenance point of motor 2 and transmission mechanism 3 is directly exposed through maintenance window 4, without digging out the device body 1 as a whole, the fault can be checked or the component can be replaced, the problem that the traditional buried device maintenance needs to damage the ground and the time is extremely long can be solved, the detachable maintenance cover plate 5 is fixed by screw, the balance sealing strength and the convenience of disassembly and assembly, ensure that the waterproof performance can still be restored after high frequency maintenance, the sealing structure between the maintenance window 4 and the detachable maintenance cover plate 5 and the shell of the device body 1 cooperate, form double waterproof barrier, resist the erosion of underground water pressure, soil corrosion and other harsh environment, the size of the maintenance window 4 is adapted to the standard tool operation space, and the opening position is accurately corresponding to the installation axis of motor 2 and transmission mechanism 3, support the local maintenance without disassembling the transmission chain.

[0024] As the preferred embodiment of the above, as Figures 1-4 shown, the maintenance window 4 and the detachable maintenance cover plate 5 installation position are provided with maintenance gap 6.

[0025] Specifically, the detachable maintenance cover plate 5 can be quickly disassembled through the maintenance gap 6, and the maintenance efficiency is improved.

[0026] As the preferred embodiment of the above, as Figures 1-4 shown, the sealing structure between the maintenance window 4 and the detachable maintenance cover plate 5 is waterproof glue.

[0027] Specifically, the micro gap between the maintenance window 4 and the detachable maintenance cover plate 5 is filled with waterproof glue to form a dead angle-free sealing layer, effectively preventing groundwater, moisture and sand from penetrating, and the peelable waterproof glue is selected, which can be easily peeled off by tools during maintenance, avoiding damage to the surface of the maintenance window 4 or the detachable maintenance cover plate 5. The glue supports repeated coating, and the sealing performance can be restored by recoating after each maintenance, without replacing the sealing element, reducing long-term operation and maintenance costs. The waterproof glue has a certain elasticity after curing, which can absorb the extrusion stress of the buried soil layer on the detachable maintenance cover plate 5, prevent the cover plate from deforming due to external force and cause sealing failure, the glue coating process is simple and easy to automate, ensuring the consistency of the sealing performance of each maintenance window 4 in batch production.

[0028] As a preferred embodiment of the above, as shown in Figures 1-4 The sealing structure between the maintenance window 4 and the detachable maintenance cover plate 5 is a sealing gasket.

[0029] Specifically, the gap between the maintenance window 4 and the detachable maintenance cover plate 5 is filled by the sealing gasket through compression to form a uniform pressure sealing surface, effectively preventing groundwater, moisture and sand from penetrating, and the sealing gasket is designed independently, which can be taken out and checked or replaced separately during maintenance without damaging the structural integrity of the maintenance window 4 or the detachable maintenance cover plate 5. The sealing gasket is preformed and placed directly in the sealing groove of the maintenance window 4 or the detachable maintenance cover plate 5 during installation, without the need for on-site glue coating or curing waiting, simplifying the production and maintenance process.

[0030] As a preferred embodiment of the above, as shown in Figures 1-4 The sealing ring 10 is arranged inside the device body screw fixing position 7.

[0031] As a preferred embodiment of the above, as shown in Figures 1-4 The device body screw fixing position 7 is arranged around the device body 1 to form a plurality of reinforcing fixing ribs.

[0032] Specifically, the sealing ring 10 is arranged in the screw fixing position 7, directly blocking the path of moisture penetrating into the device body 1 along the screw hole, and the sealing ring 10 and the screw fixing position 7 form a radial compression seal to ensure that the sealing ring is uniformly stressed when the screw is tightened, avoiding the defects that the sealing glue around the screw hole is easy to crack or fall off in the traditional scheme. The screw fixing position 7 of the device body is arranged protruding around the device body 1 to form a plurality of reinforcing fixing ribs, which significantly improves the tensile strength and compression resistance of the screw connection area. The distribution density of the reinforcing fixing ribs matches the stress direction of the screw, ensuring that the detachable maintenance cover plate 5 can still be tightly fixed after frequent opening and closing, avoiding sealing failure. The sealing ring 10 is arranged in the screw fixing position 7, solving the problem of water penetration of the screw hole of the traditional buried device, so that the device body 1 can still maintain permeation protection after long-term burial. It is especially suitable for flooded areas and sludge environments.

[0033] As a preferred embodiment of the above embodiment, as shown in Figures 1-4 The transmission mechanism 3 passes through the output shaft of the device body 1 and is provided with an output sealing element 8. The size of the output sealing element 8 changes with the use scene.

[0034] As a preferred embodiment of the above embodiment, as shown in Figures 1-4 The device body 1 shell bottom is provided with an encoder placement position 9.

[0035] Specifically, the encoder placement position 9 provides a special installation space for high-precision encoders, which can monitor the motor 2 speed and transmission mechanism 3 position in real time, realize accurate control of the opening and closing angle of the door and window, and solve the problem that the traditional buried device cannot accurately control the movement position. The encoder placement position 9 is integrated on the bottom of the device body 1 shell, fully utilizing the buried space, and avoiding occupying additional volume.

[0036] The basic principles, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
