Description

Technical Field

[0001] This application relates to the technical field of cold box sockets, and particularly to a cold box socket for real-time monitoring of the power supply end state. Background Art

[0002] In busy ports and freight yards, refrigerated containers play a crucial role. These special containers can maintain a constant low-temperature environment to ensure the freshness and quality of perishable goods during long-distance transportation. Behind all this, an efficient and reliable power supply system is essential. Refrigerated containers are usually equipped with their own diesel generators for power supply during transportation. But once they arrive at the port or yard, they are connected to the shore power system through special sockets. The design of these sockets must take into account various environmental factors such as high humidity and salt corrosion, so they usually adopt high-standard protection levels such as IP67 to ensure safe and reliable operation under harsh conditions. The method of power supply through sockets for refrigerated containers not only ensures the freshness of goods during transportation but also provides a solid guarantee for the safe operation of ports and freight yards. These seemingly insignificant sockets play an indispensable role in ensuring the efficient operation of the global cold chain logistics.

[0003] In cold chain logistics, temperature monitoring is crucial because temperature changes directly affect the quality and safety of goods. Therefore, the socket needs to have the function of real-time temperature monitoring to ensure that the temperature inside the refrigerated container always remains within the set range; in addition, whether the plug of the refrigerated container is plugged in place is also an important part of the detection. Once the plug is not correctly connected, it may lead to unstable power supply, which in turn affects the refrigeration effect of the refrigerated container; the stable installation of the temperature sensor is also a prerequisite for accurate temperature monitoring; in summary, how to integrate the detection structure for plugging in place, the temperature detection structure, and the installation structure of the temperature sensor on the socket has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0004] This device provides a cold box socket for real-time monitoring of the power supply end state, and the specific implementation is as follows:

[0005] A cold box socket for real-time monitoring of the power supply end state, comprising:

[0006] A power supply head and a cold box power receiving plug that are inserted into each other, and a power supply cable is connected to the end of the power supply head;

[0007] A seat body for installing the power supply head, which internally integrates a translation block that slides along the insertion direction of the cold box power receiving plug. A proximity switch for detecting the sliding of the translation block in place is connected to the end of the seat body. The cold box power receiving plug is inserted to force the translation block to displace, and the proximity switch is used to detect whether the cold box power receiving plug is accurately inserted;

[0008] A temperature sensor integrated at the end of the power supply head, with the probe end of the temperature sensor abutting against the joint position of the power supply cable, monitors the temperature of each power supply line in the power supply cable in real time.

[0009] Based on the above technical solution, by installing a proximity switch and a translation block on the seat body, when the cold box power receiving plug is inserted, the translation block will be pushed and thus trigger the proximity switch. This way can accurately detect whether the plug has been fully inserted in place, ensuring the continuity and stability of power supply; by installing a temperature sensor at the joint position of the power supply cable on the seat body, real-time monitoring of the temperature of each power supply line can be achieved, so that abnormal temperature conditions can be detected in time, preventing problems such as overheating from occurring, and ensuring the safe operation of the equipment.

[0010] Preferably, the seat body is a circular cavity with axial conduction, a power supply head is installed at its end, and a limiting guide groove for the cold box power receiving plug to be inserted directionally is provided along its length at the other end.

[0011] Preferably, the translation block is L-shaped, it is slidably connected to the circular cavity, one end of the translation block is used to abut against the plug body of the cold box power receiving plug, and a spring is provided between the other end and the seat body.

[0012] Based on the above technical solution, the automatic reset function of the translation block is realized by setting a spring. The spring is installed on the back of the translation block. When the cold box power receiving plug is inserted, the translation block moves under pressure, and at this time the spring is compressed; when the cold box power receiving plug is pulled out, due to the elastic force of the spring, the translation block will automatically return to the initial position, thus releasing the trigger of the proximity switch; as the translation block resets, the proximity switch is no longer triggered, and the remote control center will recognize that the plug has been pulled out.

[0013] Preferably, the front of the power supply head is set as a socket female head for plugging in with the plug male head in the cold box power receiving plug, and a circular wire insertion hole for the power supply cable to be inserted is provided on the back.

[0014] Preferably, it further includes a pressing structure composed of an arc-shaped abutting block and a bolt. Long guide grooves are communicated at each circular wire insertion hole, and an arc-shaped abutting block is slidably installed in the long guide groove, and the bolt is screwed to the arc-shaped abutting block.

[0015] Based on the above technical solution, the pressing structure is a conventional existing structure for the installation of the power supply cable.

[0016] Preferably, the temperature sensor is arranged in the long guide groove, it is arranged side by side with the pressing structure, and its probe end abuts against the arc-shaped abutting block.

[0017] Preferably, it further includes a clamping structure arranged on the side of the temperature sensor, which includes an externally threaded hexagonal head, a screw rod and an abutting block integrated; the screw rod is screwed to the main body of the clamping structure, an open port is laterally opened at the position of the externally threaded hexagonal head in its main body, and the abutting block faces the side of the long guide groove.

[0018] The long guide groove on the seat body is also used to accommodate the temperature sensor. One end of the abutting block contacts the temperature sensor, and the other end is adjusted through a pressing structure. By using a wrench to turn the external hexagonal head, the outward expansion of the abutting block is achieved. When the abutting block expands outward, it can tightly abut against the long guide groove to ensure the stable installation of the temperature sensor in the long guide groove, firmly fixing the temperature sensor in the long guide groove and keeping it stable even under vibration and shaking, ensuring the accuracy of temperature monitoring.

[0019] In summary, the present application includes the following beneficial technical effects:

[0020] 1. By installing a proximity switch and a translation block on the seat body of the present utility model, after the cold box power receiving plug is inserted, it pushes the translation block and then triggers the proximity switch, enabling the detection of whether the cold box power receiving plug is plugged in place.

[0021] 2. By installing a temperature sensor at the joint position of the power supply cable on the seat body in the present utility model, real-time monitoring of the temperature of each power supply line can be achieved.

[0022] 3. The structure of the present utility model is simple. By setting a clamping structure, turning the external hexagonal head with a wrench can achieve the outward expansion of the abutting block, and then achieve the stable installation of the temperature sensor in the long guide groove.
