Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a motor power supply quick switching device and building pump station equipment to solve the technical problems of low wiring efficiency and insufficient power supply stability in the prior art.
[0023] To achieve the above-mentioned technical objectives, this application adopts the following technical solution: like Figures 1-4 As shown. In a first aspect, this application provides a quick-connection device for motor power supply, including a junction box 1, a motor connection cable 2, and a power connection cable 3.
[0024] One end of the motor connection line 2 is electrically connected to the junction box 1, and the other end is provided with a first quick connector 21.
[0025] One end of the power connection cable 3 is provided with a second quick connector 31, and the first quick connector 21 and the second quick connector 31 are detachably connected.
[0026] The first quick connector 21 is provided with at least one snap-fit element 22, and the second quick connector 31 has at least one snap-fit groove 32 inside. The snap-fit element 22 snaps into the snap-fit groove 32 to realize the electrical connection between the first quick connector 21 and the second quick connector 31.
[0027] Fix one end of the motor connection cable 2 to the motor junction box 1 and complete the electrical connection, while the first quick connector 21 of the other end is in the ready-to-connect state; connect the second quick connector 31 of the power connection cable 3 to the power supply end.
[0028] When it is necessary to power the motor or restore power after maintenance, the operator holds the first quick connector 21, aligns it with the second quick connector 31, and pushes it inward in a straight line.
[0029] As the first quick connector 21 is inserted, at least one snap-fit element 22 on it gradually contacts the corresponding snap-fit groove 32 inside the second quick connector 31. With continued force, the snap-fit element 22 overcomes slight elastic resistance and smoothly slides into and engages within the snap-fit groove 32. This process not only provides axial positioning and locking for the quick connector, preventing accidental dislodgement, but more importantly, it triggers tight contact between the internal conductive ends.
[0030] While the snap-fit component 22 is fully embedded in the snap-fit slot 32, the conductive terminals inside the first quick connector 21 and the second quick connector 31, such as copper contacts, are tightly fitted through precise structural design, thereby forming a complete electrical path. Current flows from the power connection line 3 through the second quick connector 31 and the first quick connector 21, and finally to the motor connection line 2 to power the motor.
[0031] When disconnection is required, force is applied to the snap-fit connector 22, causing it to disengage from the snap-fit slot 32. This releases the mechanical lock between the quick connectors, simultaneously separating the conductive terminals and cutting off the circuit, thus completing a fast and reliable connection and disconnection process.
[0032] This application achieves a detachable and secure electrical connection between the first quick connector 21 and the second quick connector 31 by setting a snap-fit element 22 on the first quick connector 21 and opening a corresponding snap-fit groove 32 inside the second quick connector 31. This structure completely changes the traditional cumbersome and time-consuming method of motor wiring. When maintaining or replacing motors in confined spaces such as building pump stations, operators no longer need to perform complex wire connections. They only need to align and plug in the first quick connector 21 and the second quick connector 31, and the snap-fit element 22 will automatically embed into the snap-fit groove 32, completing the connection instantly. This not only significantly shortens wiring time and greatly improves maintenance efficiency, but also enables rapid restoration of equipment operation in emergency situations, such as a fire pump 9 motor failure, providing strong protection for fire safety.
[0033] In some embodiments of this application, the first quick connector 21 is provided with a limiting member 23 inside, and the second quick connector 31 is provided with a limiting groove 33 inside, wherein the limiting member 23 is embedded in the limiting groove 33.
[0034] When the first quick connector 21 and the second quick connector 31 are inserted, the limiting member 23 first aligns with the limiting groove 33 and guides both into place. As the insertion deepens, the limiting member 23 is fully embedded in the limiting groove 33. This process not only provides precise axial positioning for the quick connector connection, ensuring that the snap-fit member 22 and the snap-fit groove 32 can be accurately aligned and engaged, but more importantly, it provides a stable radial support between the quick connectors. Through this dual cooperation, it effectively prevents the quick connectors from becoming misaligned, loose, or poorly connected due to external forces such as vibration and pulling during equipment operation or maintenance, thereby greatly enhancing the stability of the connection and the reliability of electrical contact, ensuring the continuous and safe power supply to the motor.
[0035] In some embodiments of this application, the limiting member 23 is fixedly connected to the center of the first quick connector 21, and a plurality of the snap-fit members 22 are arranged in an equidistant ring around the limiting member 23 and along the end face of the first quick connector 21.
[0036] The central limiting component 23 serves as a guiding reference, ensuring the initial alignment accuracy during quick-connect coupling. Meanwhile, the multiple ring-shaped locking components 22 evenly distribute the radial force during connection, ensuring balanced stress throughout the process and preventing damage or deformation caused by excessive stress at a single point. The advantages of this design are that it not only significantly improves the smoothness and positioning accuracy of quick-connect coupling insertion, ensuring quick and reliable completion of each connection, but its symmetrical structure also enhances overall torsional and vibration resistance, further guaranteeing the long-term stability and safety of the power connection under complex operating conditions.
[0037] In some embodiments of this application, an early warning component is also included, which includes a pressure sensor 4 disposed on the inner wall of the limiting groove 33, a controller 5 signal-connected to the pressure sensor 4, and an audible and visual alarm 6 signal-connected to the controller 5.
[0038] Under normal connection conditions, the limiting component 23 is securely embedded in the limiting groove 33, applying a stable pressure value to the pressure sensor 4. If the connection becomes loose due to vibration, external force, or aging, the pressure between the limiting component 23 and the limiting groove 33 will change significantly. The pressure sensor 4 sensitively detects this pressure fluctuation and transmits the signal to the controller 5 in real time. After analysis and judgment, the controller 5 immediately triggers the audible and visual alarm 6 to sound an alarm. The advantage of this design is that it transforms traditional passive fault diagnosis into proactive early warning, promptly alerting staff to handle issues before connection problems lead to serious accidents such as poor contact, electric arcs, or even power outages. This greatly improves the reliability and safety of the system, effectively ensuring the continuous and stable operation of critical equipment such as building pump stations.
[0039] In some embodiments of this application, a mounting base 7 is also included, which is fixedly disposed on the side of the second quick connector 31 away from the first quick connector 21, and the controller 5 and the audible and visual alarm 6 are both mounted on the mounting base 7.
[0040] By integrating and fixing the controller 5 and electronic components such as the audible and visual alarm 6 onto the side of the second quick connector 31 away from the first quick connector 21, the core control unit is physically separated from the quick connector body. Isolating the relatively delicate and impact-sensitive electronic components from the quick connector body, which bears the mechanical connection and current transmission, effectively avoids damage to the controller 5 and alarm caused by vibrations or collisions that may occur during insertion, removal, or routine maintenance, significantly improving the durability and operational stability of the entire warning assembly.
[0041] In some embodiments of this application, a storage battery 8 is also included, which is mounted on the mounting base 7 and electrically connected to the pressure sensor 4, the controller 5, and the audible and visual alarm 6, respectively.
[0042] Battery 8 provides independent power to pressure sensor 4, controller 5, and audible and visual alarm 6, forming a complete and self-sufficient early warning system. This ensures that the early warning components can maintain normal operation even in extreme situations without external power, such as main power line failure or equipment maintenance.
[0043] In some embodiments of this application, a sealing assembly is also included, which includes a sealing groove 24 formed inside the limiting member 23 and a sealing ring 34 fixed to the inner wall of the second quick connector 31, wherein the sealing ring 34 engages with the sealing groove 24.
[0044] When the first quick connector 21 and the second quick connector 31 are connected and locked together, the sealing ring 34 is compressed and tightly embedded in the sealing groove 24, thus forming a reliable physical barrier inside the quick connector. The advantage of this design is that it not only effectively prevents corrosive or conductive impurities such as dust, water vapor, and moisture from the external environment from entering the core electrical contact area of the quick connector, preventing power supply failures caused by oxidation, short circuits, or poor contact, but also significantly improves the device's environmental adaptability under harsh operating conditions. Especially for typical applications such as humid and dusty building pump stations, this sealing component ensures long-term stability and safety of the connection, greatly extending the service life of the entire adapter and reducing maintenance frequency and costs.
[0045] In some embodiments of this application, the outer surfaces of the first quick connector 21 and the second quick connector 31 are provided with an array of protrusions and grooves.
[0046] The raised and recessed areas create a high-friction, non-slip texture. When operators need to manually insert, remove, or tighten the quick-connect coupling, these raised and recessed areas effectively increase the contact area between the hand and the coupling surface, providing a mechanical interlocking effect and excellent grip and anti-slip properties. This significantly improves operational safety and convenience.
[0047] In some embodiments of this application, a locking assembly is also included, the locking assembly including a locking ring rotatably sleeved on the outer periphery of the first quick connector 21, and a locking protrusion disposed on the outer periphery of the second quick connector 31 and cooperating with the locking ring, the locking ring being rotatably engaged with the locking protrusion.
[0048] By adding a locking component, a secondary mechanical lock is provided for the quick-connect coupling, further enhancing the stability of the connection. After the first quick-connect coupling 21 and the second quick-connect coupling 31 are initially inserted, the rotatable locking ring rotates, causing its inner wall or specific structure to firmly engage or lock with the locking protrusions on the outer periphery of the second quick-connect coupling 31, thus tightly clamping the two quick-connect couplings together and forming a mechanical safety barrier against loosening. This double protection, based on the quick-connect coupling's own locking mechanism, effectively resists continuous vibration, impact, or axial tension, completely eliminating the potential risk of loosening due to long-term operation. It ensures that even under harsh working conditions, the power connection remains absolutely reliable, providing the highest level of physical protection for the stable operation of critical equipment such as motors.
[0049] Secondly, this application also provides a building pump station equipment, including a fire pump 9 and a motor power quick-connect device as described in any embodiment of the first aspect, wherein the junction box 1 is disposed on the top of the fire pump 9 and electrically connected to the motor of the fire pump 9.
[0050] First, when assembling the first quick connector 21 and the second quick connector 31, the first quick connector 21 can be inserted into the corresponding limiting groove 33 of the second quick connector 31. The mutual cooperation between the limiting member 23 and the limiting groove 33 provides precise positioning and stable support for the connection, preventing misalignment or loosening during operation, and presets a pressure value for the controller 5. At this time, the snap-fit member 22 at the first quick connector 21 will insert into the snap-fit groove 32 in the second quick connector 31, making them snap-fitted. However, if the operator is negligent or the connection is not tight, the connection at the limiting groove 33 may loosen, causing a pressure change. The pressure sensor 4 will then transmit a signal to the controller 5, which will then trigger the audible and visual alarm 6 to sound an alarm, reminding the staff to handle the situation promptly and effectively preventing accidents such as poor contact or power outages caused by connection problems. In addition, the engagement of the sealing groove 24 and the sealing ring 34 can effectively prevent dust, moisture and other substances from entering the interior of the first quick connector 21 and the second quick connector 31, avoiding the impact of external environmental factors on the stability and safety of the power connection, and is especially suitable for building pump station environments with high humidity and dust.
[0051] In this invention, the structural design of the first quick connector 21 and the second quick connector 31, along with the snap-fit component 22 and the snap-fit groove 32, changes the traditional cumbersome wiring method. When replacing a motor in the confined space of a building pump station, operators no longer need to perform complex wire matching; they only need to quickly connect the first quick connector 21 and the second quick connector 31, and the snap-fit component 22 will automatically embed into the snap-fit groove 32, thus achieving a quick connection between the motor connection wire 2 and the power connection wire 3, significantly shortening wiring time and greatly improving maintenance efficiency. Even in emergencies, such as a malfunction in the motor of the fire pump 9, wiring can be quickly completed to restore equipment operation, providing strong protection for fire safety. Simultaneously, through real-time monitoring by the pressure sensor 4 and the linkage warning of the audible and visual alarm 6, loose connection problems can be proactively detected and alerted, effectively preventing accidents such as poor contact and power outages, further ensuring the long-term stable operation of the building pump station equipment.
[0052] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include: This application achieves a detachable and secure electrical connection between the first quick connector 21 and the second quick connector 31 by setting a snap-fit element 22 on the first quick connector 21 and opening a corresponding snap-fit groove 32 inside the second quick connector 31. This structure completely changes the traditional cumbersome and time-consuming method of motor wiring. When maintaining or replacing motors in confined spaces such as building pump stations, operators no longer need to perform complex wire connections. They only need to align and plug in the first quick connector 21 and the second quick connector 31, and the snap-fit element 22 will automatically embed into the snap-fit groove 32, completing the connection instantly. This not only significantly shortens wiring time and greatly improves maintenance efficiency, but also enables rapid restoration of equipment operation in emergency situations, such as a fire pump 9 motor failure, providing strong protection for fire safety.
