Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, and more specifically, to a portable electric gate opening and closing device. Background Technology

[0002] As a crucial control facility in water conservancy projects, the opening and closing of sluice gates directly affects water flow regulation and safety. Currently, sluice gates are opened and closed primarily using two methods:

[0003] The first method is the traditional manual hand-crank operation. The operator inserts a crank handle into the rotating shaft of the gate hoist, rotating it clockwise to open the gate and counter-clockwise to close it. This method requires no external power supply, has a simple structure, and is suitable for most water conservancy scenarios. However, in actual use, especially with medium to large gates, completing a full opening or closing operation typically requires continuous cranking for 30 minutes to 2 hours or even longer. This is physically demanding, inefficient, and places high demands on the physical strength and endurance of management personnel, clearly unsuitable for long-term or emergency operations.

[0004] The second method involves remote control using electric gate-opening equipment. This system, consisting of a motor, reducer, remote terminal, 4G communication module, and central control platform, automates the opening and closing of the gates. This method offers a high level of automation, significantly reducing manpower and improving operational efficiency. However, this type of system relies on complex hardware and software integration. In case of equipment failure or communication issues, on-site repairs by specialized technicians are required, resulting in long lead times and high costs. Furthermore, during equipment downtime, normal water supply cannot be guaranteed, leading to passive management and resource waste.

[0005] To address these issues, a portable electric gate opening and closing device is proposed. Utility Model Content

[0006] The present invention aims to provide a portable electric gate opening and closing device to solve or improve at least one of the above-mentioned technical problems.

[0007] In view of this, the first aspect of the present invention is to provide a portable electric gate opening and closing device.

[0008] The first aspect of this utility model provides a portable electric gate opening and closing device, including a housing, a reducer, a high-torque motor, a coupling, a portable handle, and a power interface; the high-torque motor and the reducer are disposed inside the housing, the output end of the high-torque motor is connected to the input end of the reducer, and the coupling is used to connect the output end of the reducer to the drive shaft of the gate; the portable handle is mounted on the top of the outer wall of the housing; a spacer cavity is formed between the outer wall of the high-torque motor and the inner wall of the housing, the spacer cavity extends axially along the output end of the high-torque motor, and the portable handle corresponds to the spacer cavity; the power interface is disposed on the side wall of the housing, and the power interface is connected to the power input end of the high-torque motor; the reducer includes a base and a mounting ear, the circumferential side wall of the base is connected to the inner wall of the housing, and the outer wall of the high-torque motor is connected to the end wall of the base; the mounting ear is used for fixed assembly with the outside.

[0009] The beneficial effects of this utility model compared with the prior art are as follows:

[0010] Relying on the combination of a high-torque motor and a reducer arranged coaxially inside the casing, the output is directly connected to the gate drive shaft via a coupling, which can complete the gate's full opening or closing operation in a shorter time. This is an order of magnitude more efficient than manual hand-cranking, completely freeing up the physical burden on on-site management personnel.

[0011] An axially extending spacer cavity is provided between the outer wall of the high-torque motor and the inner wall of the housing to form a buffer, which significantly reduces the transmission of motor vibration to the housing, avoiding fatigue caused by prolonged holding and the impact of vibration on the operator's arm.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] Please see Figure 1-2 The following describes a portable electric gate opening and closing device according to some embodiments of the present invention.

[0021] The first aspect of this utility model provides a portable electric gate opening and closing device. In some embodiments of this utility model, such as... Figure 1-2 As shown, the portable gate electric opening and closing device includes a housing 1, a reducer 2, a high-torque motor 3, a coupling 4, a portable handle 5, and a power interface 301.

[0022] The high-torque motor 3 and the reducer 2 are installed inside the housing 1. The output end of the high-torque motor 3 is connected to the input end of the reducer 2. The coupling 4 is used to connect the output end of the reducer 2 to the drive shaft of the gate.

[0023] The portable handle 5 is installed on the top of the outer wall of the housing 1; a spacer cavity 101 is formed between the outer wall of the high torque motor 3 and the inner wall of the housing 1, the spacer cavity 101 extends axially along the output end of the high torque motor 3, and the portable handle 5 corresponds to the spacer cavity 101.

[0024] The power interface 301 is located on the side wall of the housing 1 and is connected to the power terminal of the high torque motor 3.

[0025] The reducer 2 includes a base 201 and a mounting ear 202. The circumferential side wall of the base 201 is connected to the inner wall of the outer shell 1, and the outer wall of the high-torque motor 3 is connected to the end wall of the base 201. The mounting ear 202 is used for fixed assembly with the outside.

[0026] This utility model provides a portable electric gate opening and closing device. The outer casing 1 forms a closed and robust installation space to house the two core drive units: a high-torque motor 3 and a reducer 2. The high-torque motor 3 is located inside the casing 1, and its output end is directly connected to the input end of the reducer 2. Efficient and lossless power transmission is achieved through rigid shaft coupling or flange connection. This motor provides high torque output, offering sufficient driving capability for medium and large gates with high resistance during opening and closing.

[0027] The reducer 2 is used to convert the high-speed output of the motor into a low-speed, high-torque working state. Its output end is connected to the coupling 4, which is then matched and connected to the drive shaft of the gate hoist, realizing the final output of power from the entire device to the gate hoisting mechanism. Through this series structure arrangement, the drive path is simple and clear, and the mechanical loss during torque transmission is effectively controlled.

[0028] The outer casing 1 adopts a metal cylindrical structure, serving both structural support and protection functions. It not only secures internal components but also resists external moisture, dust, or mechanical impact, enhancing the equipment's adaptability to outdoor hydraulic environments. A portable handle 5 is mounted on the top of the outer casing 1, positioned directly above the partition cavity 101. The partition cavity 101 is formed between the outer wall of the high-torque motor 3 and the inner wall of the outer casing 1, extending axially along the motor's output direction. This structure, on the one hand, physically reduces the transmission of high-frequency vibrations generated during motor operation to the outer casing 1 and the handle, preventing fatigue or discomfort during handheld use; on the other hand, structurally, it provides a load-bearing buffer for the installation of the top portable handle 5, improving overall grip stability and safety.

[0029] The power interface 301 is located on the side wall of the housing 1, facilitating quick connection when the device is placed vertically or held in hand. This power interface 301 connects directly to the power terminal of the high-torque motor 3 via a cable, resulting in high integration and a short electrical path, effectively reducing energy consumption and voltage loss. Furthermore, by switching the polarity of the external power supply, the operator can control the motor to rotate forward or backward, corresponding to the opening or closing of the gate, thus achieving convenient opening and closing operations without the need for a complex control system.

[0030] The reducer 2 body also includes a base 201 and mounting ears 202. The base 201 is disc-shaped, and its circumferential sidewalls are attached to the inner wall of the housing 1. It is fixed inside the housing by threads or slots, which not only ensures that the reducer 2 body does not shift during operation, but also provides a stable mounting base for the high-torque motor 3. The outer wall of the high-torque motor 3 is fixedly connected to the end wall of the base 201, so that the motor and reducer 2 form an integral rigid connection unit, avoiding micro-displacement or loosening under high load or frequent start-stop conditions.

[0031] The mounting ears 202 are located on the edge of the housing of the reducer 2 and are distributed circumferentially along the output end. They usually have through holes and can be connected and fixed to the external base, guide rail or hoist bracket, which facilitates the device to achieve rapid alignment and rigid positioning under field conditions, and improves the overall stability and output accuracy of the machine.

[0032] Overall, the motor provides power, the reducer 2 regulates the speed and torque, the coupling 4 connects to the drive shaft, the housing 1 provides protection and structural support, the handle and the partition cavity 101 work together to achieve human-machine grip and vibration reduction, and the power interface 301 realizes energy access and direction control.

[0033] In any of the above embodiments, the outer shell 1 is a cylindrical structure, one end of the outer shell 1 is an open structure, the open structure is sealed by a sealing plate 6, an assembly ring 601 is installed on the side wall of the sealing plate 6, and the side wall of the outer shell 1 is provided with an assembly hole 103 corresponding to the assembly ring 601. The assembly ring 601 and the assembly hole 103 are fixedly connected by bolts.

[0034] In this embodiment, the sealing plate 6 has an end-face sealing structure, tightly sealing the opening of the outer shell 1. Its material is typically a high-strength metal or corrosion-resistant material consistent with the outer shell 1, ensuring overall strength consistency and resistance to environmental interference. To achieve high-strength fixation and sealing contact between the sealing plate 6 and the outer shell 1, an assembly ring 601 is provided on the side wall of the sealing plate 6. This assembly ring 601 serves as a fixing component, its outer diameter matching the inner wall of the outer shell 1, and is inserted into and positioned within the inner cavity of the outer shell 1 during assembly.

[0035] The side wall of the outer casing 1 has several mounting holes 103 corresponding to the mounting ring 601. The axial position of these mounting holes 103 is aligned with the threaded holes or through holes of the mounting ring 601, which facilitates the secure locking of the mounting ring 601 into the structure of the outer casing 1 by bolt connection. The bolt connection not only provides reliable mechanical fixing force, but also ensures a stable and uniform end face pressing contact between the sealing plate 6 and the outer casing 1, thereby achieving the requirements of sealing, protection and structural integrity.

[0036] In any of the above embodiments, a groove is provided on the end side wall of the reducer 2 away from the base 201, and a water-blocking cavity 102 is formed between the inner wall of the groove and the inner wall of the outer shell 1. The water-blocking cavity 102 is located between the sealing plate 6 and the base 201.

[0037] In this embodiment, an annular gap is formed between the inner wall of the groove and the inner wall of the cylindrical outer shell 1, which is referred to as the water-blocking cavity 102 in this device. The presence of the water-blocking cavity 102 ensures that even if a small amount of external water vapor permeates at the connection of the sealing plate 6, it will first be blocked in this cavity and cannot directly enter the core cavity of the reducer 2 and the motor.

[0038] The water-blocking cavity 102 is positioned between the sealing plate 6 and the base 201 of the reducer 2, precisely at the transition section between the outermost closed end of the entire device and the internal main drive unit, providing a natural buffer and isolation function. When external moisture or water attempts to enter along the installation direction of the coupling 4 or the cable interface direction, it must first pass through the sealing plate 6, then through the gap between the assembly ring 601 and the housing 1 in the assembly hole 103, before finally reaching the water-blocking cavity 102 formed by the groove. The annular structure and micro-gap characteristics of the water-blocking cavity 102 make it easy for water vapor to condense or stagnate, preventing it from penetrating further. Filling the water-blocking cavity 102 with silica gel desiccant or adding a sealing ring can further enhance the waterproof rating.

[0039] In any of the above embodiments, along the radial direction of the input end of the reducer 2, the groove corresponds to the mounting ring 601 and the mounting hole 103.

[0040] In this embodiment, the radial projection of the components distributed along the circumference of the input end of the reducer 2 is exactly at the corresponding positions of the assembly ring 601 and the assembly hole 103. The assembly ring 601 is a structure on the side wall of the sealing plate 6, used to insert into the inner cavity of the housing 1 and mate with the assembly hole 103, and the structure is locked by bolts. The assembly hole 103 is a through hole structure provided on the side wall of the housing 1, used to provide a path for the bolts to pass through.

[0041] After the reducer 2 is installed into the housing 1 and positioned, the outer edge of the assembly ring 601 corresponds exactly to the location of the groove. This ensures that after the entire sealing structure is assembled, the groove is positioned exactly inside the bolt connection area, i.e., on the extension line from the bolt hole inward. This means that even if there are tiny gaps or seepage paths in the connection area, liquid or water vapor must first pass through the assembly hole 103 before entering the water-blocking cavity 102 formed by the groove, thus extending the seepage path and effectively slowing down the rate at which water vapor enters the device.

[0042] In any of the above embodiments, the mounting ear 202 has a through hole along the circumference of the output end of the reducer 2, and the through hole is inserted into the external positioning rod.

[0043] In this embodiment, to improve the positioning stability and rapid installation capability of the device during field use, a mounting ear 202 and a through-hole mating structure are introduced into the structural design of the output end of the reducer 2. Specifically, the mounting ear 202 is arranged circumferentially along the output end of the reducer 2, with multiple distribution points, and has through holes for insertion and mating with external positioning rods on site, thereby completing the rapid alignment and stable installation between the device and the gate opening and closing machine.

[0044] The mounting lug 202 is a structural reinforcement component extending outward from the housing of the reducer 2. Two or more lugs are typically arranged symmetrically along the circumference of the output port, enabling it to perform circumferential positioning while also resisting radial forces and torques during transmission. A through-hole penetrates each mounting lug 202, and its diameter matches the size of the positioning rod on the on-site opening and closing device, ensuring an interference fit or a close fit during insertion.

[0045] In any of the above embodiments, the coupling 4 is detachably connected to the output end of the reducer 2.

[0046] In this embodiment, to improve the adaptability and maintenance convenience of the device, the coupling 4 adopts a detachable connection structure and is installed at the output end of the reducer 2. This allows the coupling 4, as the end connection element for power transmission, to meet the requirements of high torque transmission while also possessing flexible assembly and replacement characteristics, making it suitable for various types of gate drive shaft interfaces.

[0047] Coupling 4 is used to effectively transmit the rotational power generated by the output shaft of reducer 2 to the drive shaft of the gate opening and closing mechanism, and is a key connecting component in the power path. In this structure, coupling 4 and the output shaft of reducer 2 are connected in a detachable manner, typically through keyway fit, screw locking, snap ring engagement, or threaded connection to achieve a firm but not permanent mechanical connection. Through this connection structure, coupling 4 meets the transmission rigidity requirements while also possessing the characteristic of quick assembly and disassembly.

[0048] In any of the above embodiments, the power interface 301 is used to connect an external power source to the power terminal of the high-torque motor 3, and to control the rotation direction of the high-torque motor 3 by switching the positive and negative wiring methods.

[0049] In this embodiment, the power interface 301 acts as a bridge between the external power supply and the internal drive. Its location on the side wall of the housing 1 facilitates quick connection by the operator during field use. The power interface 301 is directly connected to the power terminal of the high-torque motor 3, forming a power input path.

[0050] The device uses a DC power supply drive, so the rotation direction of the high-torque motor 3 can be controlled by adjusting the polarity of the power supply. Specifically, during use, the operator connects an external controllable DC power supply device through the power interface 301. When the positive terminal is connected to the positive terminal of the motor and the negative terminal is connected to the negative terminal, the motor rotates in the predetermined direction, driving the reducer 2 to open the gate. When the positive and negative terminals are connected in reverse, that is, when the positive terminal is connected to the negative terminal and the negative terminal is connected to the positive terminal, the rotation direction of the motor reverses, driving the gate to close.

[0051] In any of the above embodiments, a rubber ring is provided between the circumferential sidewall of the base 201 and the inner wall of the outer shell 1 to reduce the transmission of vibration generated by the high-torque motor 3 during operation to the outer shell 1.

[0052] In this embodiment, to improve the vibration reduction performance and handling comfort of the entire machine during operation, a rubber ring buffer structure is introduced between the base 201 of the reducer 2 and the outer shell 1. Specifically, an annular rubber ring is provided between the circumferential sidewall of the base 201 and the inner wall of the outer shell 1. The rubber ring fills and fits into the gap between the two to form a flexible buffer layer, which is used to absorb and attenuate the vibration energy generated during the operation of the transmission system.

[0053] The base 201 of the reducer 2 serves as a crucial structural component supporting the high-torque motor 3. One end is connected to the motor, while the other end is fitted inside the housing 1. Throughout its operation, it must withstand the torque load and dynamic impacts generated by the motor output. Since the motor inevitably generates periodic mechanical vibrations during high-load, variable-speed operation, if these vibrations are directly transmitted to the housing 1, it will cause discomfort during handheld operation, structural loosening, or noise amplification.

[0054] The rubber ring effectively blocks the rigid contact path between the base 201 and the outer shell 1, allowing the high-frequency vibrations generated by the motor to be transmitted to the rubber buffer layer first. These vibrations are then absorbed, converted, and gradually attenuated through the elastic deformation of the rubber material, significantly reducing the efficiency of vibration propagation to the outer shell 1. Simultaneously, the rubber ring also provides structural limiting and sealing functions, filling the small assembly gaps between the base 201 and the outer shell 1, enhancing the positioning stability of the base 201 within the cavity, and preventing loosening or axial movement during operation.

[0055] Working Principle: During operation, the operator first uses the portable handle 5 to move the device to the gate opening / closing mechanism position, and then engages the coupling 4 with the square tenon or keyway of the gate drive shaft. Subsequently, the through hole of the reducer 2's mounting ear 202 is inserted into the on-site positioning rod, and the mounting hole 103 of the housing 1 is secured to the mounting ring 601 with bolts. The base 201 ensures concentricity between the drive assembly and the gate axis through circumferential contact. After mechanical positioning, the external DC power cord is inserted into the power interface 301: when the positive terminal is connected to the positive end of the motor and the negative terminal to the negative end, the high-torque motor 3 rotates forward and is reduced in speed and increased in torque by the integrated reducer 2, outputting high torque at low speed. The torque is transmitted seamlessly to the gate drive shaft via the coupling 4, driving the lead screw or gear mechanism to rise, thus opening the gate. To close the gate, simply switch the power polarity; the motor rotates in reverse, the reducer 2 outputs reverse torque, and the gate descends smoothly in the opposite direction until it reaches its final position.

[0056] Throughout the opening and closing process, the rigid connection between the motor output and the reducer 2 input ensures efficient power transmission. The internal meshing gears of the reducer 2, after multi-stage reduction, provide torque tens of times greater than the motor's rated value, overcoming the gate's weight, water pressure, and frictional resistance to achieve rapid opening and closing. Once the gate reaches the predetermined position and the power is cut off, the reducer 2's self-locking characteristic keeps the gate stationary during power outages or extreme conditions. If disassembly or relocation is required, the operator only needs to loosen the positioning bolts and positioning rods to quickly separate the entire unit from the coupling 4, facilitating continued use at the next gate location. This portable-plug-open-close-disconnect closed-loop process gives the device multiple advantages, including efficient opening and closing, vibration damping and stability, waterproofing and weather resistance, and rapid on-site deployment.
