DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0019] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings: See also Figure 1 and Figure 2As shown, the present invention discloses a self-spinning manhole cover device, including a manhole cover body 1, a rotating drive mechanism 2, a locking device 3, a fan blade structure 4 and a manhole seat 5; wherein the manhole cover body 1 is composed of an upper manhole cover 101 and a lower manhole cover 102, which are tightly fixed together by a precise connection structure. Both the upper manhole cover 101 and the lower manhole cover 102 are made of high-strength, corrosion-resistant materials to ensure their stability and durability for long-term use. A high-quality sealing gasket 104 is provided on the edge of the manhole cover, and advanced sealing technology is adopted to ensure that the manhole cover has good sealing performance in a closed state to prevent rainwater leakage and odor emission. In addition, the manhole cover is also provided with reasonable water holes 105 and fan blade holes 304, which not only ensure the smooth drainage, but also provide the necessary space for the rotation of the fan blade structure 4.

[0021] like Figure 6 and Figure 8 As shown, the rotary drive mechanism 2 is a key component of the present invention for realizing automatic opening and closing of the manhole cover. The mechanism is mainly composed of related transmission components such as a motor 201, a reducer 202, a transmission shaft 203 and a coupling 204. The motor 201 uses a high-precision, low-noise stepper motor or servo motor, which has the advantages of fast response speed and high control accuracy, and can execute control instructions quickly and accurately. In order to ensure the stable operation of the motor 201 in a complex environment, its outer layer is equipped with a waterproof cover 205 and a heat dissipation device. The waterproof cover 205 can effectively prevent moisture from invading the interior of the motor to avoid motor failure due to water erosion. The heat dissipation device can promptly dissipate the heat generated during the operation of the generator to prevent the motor from overheating and damage.

[0022] The reducer 202 plays a key role in the rotary drive mechanism. It is connected to the motor 201 through a precision-machined coupling 204 to ensure the stability and accuracy of power transmission. The reducer 202 can reduce the output speed of the motor 201 and increase the output torque, thereby meeting the larger torque requirements required when the manhole cover is opened and closed. The transmission shaft 203 passes through the bottom center of the manhole cover body 1 and is firmly fixed thereto. Under the synergistic effect of the rotary drive mechanism 2, the power output by the motor 201 is adjusted by the reducer 202 and transmitted by the coupling 204, driving the transmission shaft 203 to rotate, thereby driving the fan blade structure 4 to realize the rotary opening and closing action, completing the drainage or closing function of the manhole cover.

[0023] like Figure 3As shown, the fan blade structure 4 is an important component of the present invention for achieving efficient drainage. The structure is installed inside the manhole cover body 1 and is composed of a plurality of fan blades, a middle baffle 402 and a baffle gasket 403. The fan blades are made of lightweight, high-strength materials and have good corrosion resistance and wear resistance. When the motor 201 is started and drives the transmission 203 shaft to rotate, the fan blade structure will rotate and open accordingly, forming a drainage channel, allowing the accumulated water to be quickly discharged into the underground pipe. When the drainage is completed, the motor 201 reverses and drives the fan blade structure to close, restoring the closed state of the manhole cover. The middle baffle 402 and the baffle gasket 403 play the role of supporting and fixing the fan blades, ensuring that the fan blades remain stable during rotation and reduce noise.

[0024] like Figure 4 As shown, the locking device 3 is used to lock the position of the manhole cover when it is closed to prevent the manhole cover from being accidentally opened. The device includes a lock tongue 301, a lock seat 302, a spring 302 and related transmission components. The lock tongue 301 is arranged on the edge of the manhole cover body 1 and is fixedly connected thereto; the lock seat 302 is arranged on the manhole seat 5 and is fixedly connected to the ground. When the manhole cover is closed, the lock tongue 301 is automatically snapped into the lock seat 302 under the action of the spring 302 and locks the position of the manhole cover. When unlocking, the remote control module sends an instruction to the motor controller to drive the transmission component to disengage the lock tongue 301 from the lock seat 302 to realize the unlocking function. This design not only improves the safety of the manhole cover but also facilitates the daily maintenance of the operator.

[0025] like Figure 5 and Fig.10 As shown, the design of the well seat 5 as a component that supports and fixes the entire well cover system is also crucial. The well seat 5 of the present invention is made of high-strength, corrosion-resistant materials and has excellent load-bearing capacity and stability. A waterproof layer and anti-skid texture are provided on the well seat 5 to enhance its waterproof and anti-skid properties. In addition, a reasonable space layout and support structure are also provided inside the well seat 5 to ensure that the stable operation and heat dissipation requirements of key components such as the rotary drive mechanism and the motor are met.

[0026] Example Materials and parts preparation The manhole cover body 1 uses high-strength, corrosion-resistant 304 stainless steel as the main material of the manhole cover body to ensure that it is not damaged in long-term use in outdoor environments. According to the design size, it is processed into an upper manhole cover 101 and a lower manhole cover 102 through cutting, bending, welding and other processes.

[0027] The fan blade structure 4 is made of lightweight and high-strength aluminum alloy material and is made into a fan blade by CNC machining or precision casting. The surface of the fan blade is anodized to enhance its wear resistance and corrosion resistance. At the same time, bearings and washers matching the fan blades are designed and manufactured to ensure that the fan blades rotate smoothly and without noise.

[0028] The rotary drive mechanism 2 uses a waterproof stepper motor and a planetary gear reducer as the core components of the rotary drive mechanism 2. The motor 201 must have a waterproof grade of IP67 or above to ensure stable operation in a humid environment. The reducer 202 is connected to the motor 201 through a precision-machined coupling to ensure the stability and accuracy of power transmission.

[0029] The locking device 3 designs and manufactures locking device components such as the lock tongue 301, the lock seat 302 and the spring 303. The lock tongue 301 is made of stainless steel with a polished surface; the lock seat 302 is fixed on the well seat and forms a matching relationship with the lock tongue 301. The spring 303 is made of high-quality stainless steel spring to ensure that the lock tongue 301 can automatically reset and lock when not subjected to external force.

[0030] The sealing gasket 104 is made of EPDM or silicone and is customized according to the size and shape of the manhole cover body 1. The sealing gasket 104 needs to have good elasticity and sealing performance to ensure the sealing effect of the manhole cover in a closed state.

[0031] Component assembly and debugging Connect the upper manhole cover 101 and the lower manhole cover 102 together by bolts or other fasteners, and ensure that the fan blade structure and the gasket 103 are properly installed inside. During the assembly process, pay attention to adjusting the gap between the upper manhole cover 101 and the lower manhole cover 102 to ensure that the fan blades are not hindered when rotating. After installation, check the flatness and sealing of the manhole cover body 1.

[0032] Fix the motor 201 and the reducer 202 in the reserved space inside the well seat 5 to ensure that they are firmly installed. Pass the transmission shaft 203 through the hole in the center of the well seat 5 and connect it to the output end of the reducer 202. Install the waterproof cover 205 and the guide shaft support 206 on the transmission shaft 203, and use sealant to seal the gap between the waterproof cover 205 and the transmission shaft 203. Connect the power cord of the motor 201 and turn on the power, and test the operation of the motor 201 and the reducer 202.

[0033] Install the lock tongue bracket and lock tongue 301 at the designated position on the edge of the manhole cover body 1 to ensure that the lock tongue 301 can move flexibly and reset automatically. Install the lock seat 302 on the manhole seat 5 and form a matching relationship with the lock tongue 301. Check whether the locking device 3 works properly by manually operating the opening and closing action of the manhole cover. Adjust the elastic force of the spring 303 to ensure that the lock tongue 301 can be reliably inserted into the lock seat 302 and remain in a locked state.

[0034] After assembling all the above components, the whole self-spinning manhole cover system is debugged as a whole. First, a manual operation test is performed to check whether the opening and closing action of the manhole cover is smooth and unobstructed; then the power is turned on to perform an electric operation test to observe whether the rotation opening and closing function driven by the motor is normal; at the same time, the sealing performance of the locking device 3 and the sealing gasket 104 is checked to ensure that the system operates stably and meets the design requirements.

[0035] System testing and verification Functional test: Verify the stability and reliability of the manhole cover by repeatedly opening and closing it. Check whether the motor 201, reducer 202 and transmission shaft 203 have abnormal noise or heating; observe whether the locking device 3 can be quickly locked and remain stable when the manhole cover is closed; test the sealing effect of the sealing gasket 104 when the manhole cover is closed to ensure that there is no leakage.

[0036] Waterproof performance test: Place the manhole cover in a simulated rainwater environment for waterproof performance test. Use a spray device to simulate rainwater spraying on the manhole cover surface to observe whether there is water seeping into the well or into key components such as the motor; at the same time, check the waterproof effect of the motor waterproof cover 207 and the sealant to ensure that the system has good waterproof performance.

[0037] Remote control test (if applicable): If the self-closing manhole cover of the present invention integrates a remote control module, a remote control test is required. Send control instructions to the manhole cover system through a mobile phone APP or a remote management platform to check whether it can accurately receive and execute the instructions; at the same time, test the stability and reliability of remote communication to ensure the effective implementation of the remote control function.

[0038] The remote control module is a key component of the present invention to achieve remote monitoring and automatic control. The module is connected to the motor controller through wireless communication technology, allowing the user to send instructions to the motor controller through a remote control, mobile phone APP or other remote control devices to control the start and stop of the motor, thereby realizing remote opening and closing and monitoring of the manhole cover.
