Description

Technical Field

[0001] This utility model relates to the field of temperature and humidity monitoring technology for port electromechanical equipment, and specifically to a temperature and humidity monitoring device for a port machinery cable slip ring box. Background Technology

[0002] Most port gantry cranes currently use high-voltage power supply. Due to the special nature of high-voltage power transmission systems, the core component for power transmission and conversion, namely the cable reel slip ring box, needs to maintain a suitable temperature and humidity range. If the humidity inside the slip ring box is too high, it will cause a decrease in the insulation performance of the air or insulation components between the three-phase slip rings and cable joints, resulting in phase-to-phase short circuits or grounding faults, and the cost of fault repair is high.

[0003] Existing slip ring chamber temperature control systems mainly employ passive heater control, meaning a heater is installed inside the slip ring chamber and operates continuously to achieve a dehumidification effect. Traditional slip ring chambers lack protective structures, making them susceptible to damage from external forces during use, which can affect the lifespan of internal components and the responsiveness and normal operation of sensor equipment.

[0004] Secondly, it only has a simple dehumidification function, which has insufficient dehumidification power in high humidity conditions; and it cannot reflect the temperature and humidity inside the slip ring box in real time, so it cannot effectively prevent condensation from occurring, and urgently needs to be developed. Utility Model Content

[0005] This utility model provides a temperature and humidity monitoring device for a port machinery cable slip ring box, which aims to solve the problems in the prior art.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A temperature and humidity monitoring device for a port machinery cable slip ring box includes a slip ring box body, an installation mechanism, two protective plates, and two dehumidification and heating mechanisms. The installation mechanism is mounted on the slip ring box body for assembling the slip ring box body. Mounting holes are provided on opposite sides of the slip ring box body, and the two dehumidification and heating mechanisms are respectively installed at the two mounting holes. The two protective plates are mounted opposite each other on opposite sides of the slip ring box body, and are horizontally slidably connected to and positioned on opposite sides of the slip ring box body. Openings are provided on opposite sides of the two protective plates, and the two openings are respectively directly opposite the two dehumidification and heating mechanisms.

[0008] The beneficial effects of this utility model are: the protective plate in this utility model can absorb the impact force from the external force, and has a good buffer protection effect, which greatly enhances the stability and service life of the internal equipment and components of the slip ring box, and is suitable for different scenarios; at the same time, the temperature and humidity inside the slip ring box can be monitored and regulated, and staff can deal with abnormalities in time to avoid danger, making it safe and reliable.

[0009] In addition, the installation mechanism facilitates quick assembly of the slip ring housing, making assembly convenient.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the top of the slip ring housing is also provided with the mounting hole, and the dehumidification heating mechanism is installed in the mounting hole.

[0012] The advantages of adopting the above-mentioned further solutions are that the structure is simple, the design is reasonable, and it is easy to assemble the dehumidification and heating mechanism.

[0013] Furthermore, each of the dehumidification and heating mechanisms includes a dehumidification fan and a heater, which are respectively fixedly installed at the corresponding mounting holes.

[0014] The advantages of adopting the above-mentioned further solution are that it has a simple structure and reasonable design, and the heating and dehumidification equipment composed of a dehumidifying fan and a heater can effectively heat or dehumidify the slip ring box.

[0015] Furthermore, a mounting bracket is fixedly installed at each of the mounting holes, and the mounting bracket is located on the outside of the heater; the dehumidifying fan is fixedly installed on the corresponding mounting bracket.

[0016] The advantages of adopting the above-mentioned further solution are that it has a simple structure, reasonable design, and facilitates the assembly of dehumidifying fans using the mounting bracket, making assembly convenient.

[0017] Furthermore, it also includes a temperature and humidity sensor and a PLC controller, which are respectively fixedly installed in the slip ring housing; the temperature and humidity sensor and the three dehumidification heating mechanisms are respectively communicatively connected to the PLC controller.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the temperature and humidity sensor can monitor the temperature and humidity changes inside the slip ring box, increase the function of temperature and humidity monitoring and adjustment, and can start the heating and dehumidification equipment composed of dehumidifying fan and heater in a timely manner to effectively heat or dehumidify the slip ring box.

[0019] Furthermore, it also includes an alarm, a display instrument, and control buttons. The alarm is fixedly installed on the slip ring housing, and the display instrument and the control buttons are respectively fixedly installed on the front side of the slip ring housing.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the temperature and humidity sensor can monitor the temperature and humidity changes inside the slip ring box, increase the function of temperature and humidity monitoring and adjustment, and can start the heating and dehumidification equipment composed of dehumidifying fan and heater in a timely manner to effectively heat or dehumidify the slip ring box.

[0021] Meanwhile, in conjunction with the PLC controller, the temperature and humidity signals can be promptly fed back to the external display instrument of the slip ring box for display, facilitating real-time monitoring by inspection personnel. In case of abnormalities, the alarm can promptly alert staff to stop the machine for inspection and handling, thus preventing danger and improving safety.

[0022] Furthermore, the slip ring housing has two pairs of movable grooves on opposite sides, and telescopic blocks are slidably installed in the two pairs of movable grooves. One end of each pair of telescopic blocks is connected to the two pairs of movable grooves through a buffer spring. The other end of each pair of telescopic blocks extends to the outside of the two pairs of movable grooves and is fixedly connected to the two protective plates.

[0023] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. Each protective plate is connected to two movable grooves on the slip ring box by two telescopic blocks and buffer springs. The two buffer springs make the telescopic blocks slide repeatedly, so that the protective plate can absorb the impact force from the external force and has a good buffer protection effect. It greatly enhances the stability and service life of the internal equipment and components of the slip ring box and is suitable for different scenarios.

[0024] Furthermore, each of the movable slots has guide slots on both sides, and one end of each telescopic block is slidably connected to a pair of guide slots via a guide block; the part of each protective plate corresponding to both sides of the telescopic block is fixedly connected to the corresponding side of the slip ring box via a buffer spring.

[0025] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. By combining the elasticity of buffer spring one and buffer spring two with the sliding of the guide block along the guide groove to drive the repeated extension and retraction of the telescopic block, the protective plate can absorb the impact force from the external force, which has a good buffer protection effect. It greatly enhances the stability and service life of the equipment and components inside the slip ring box and is suitable for different scenarios.

The drive assembly is mounted on the back plate and is drivenly connected to the two mounting cylinders respectively, for driving the two mounting cylinders to slide horizontally to move closer to or further away from each other.

[0027] The advantage of adopting the above-mentioned further solution is that during assembly, the two mounting cylinders are driven to move horizontally using the drive assembly, so that the two mounting cylinders move away from or closer to each other, so as to assemble the slip ring housing.

[0028] Furthermore, the drive assembly includes a rotating block, a transmission rod, a first conical tooth, two second conical teeth, and two screws. The two screws are horizontally mounted opposite each other in the second movable groove, and the two mounting cylinders are coaxially fixedly sleeved on the outside of the two screws. The two second conical teeth are coaxially fixedly sleeved on the opposite ends of the two screws. The transmission rod is vertically rotatably mounted on the top of the back plate, and its lower end extends vertically downward into the second movable groove. The conical teeth are coaxially fixedly sleeved on the lower end of the transmission rod, and they mesh with the two second conical teeth respectively. The rotating block is fixedly mounted on the upper end of the transmission rod.

[0029] The beneficial effect of adopting the above-mentioned further solution is that during assembly, the rotating block is manually rotated, and the rotating block drives the first conical tooth to rotate by the transmission rod. The first conical tooth meshes with the two second conical teeth, causing the two second conical teeth to rotate. The two second conical teeth drive the two screws and the two mounting cylinders to rotate, thereby causing the two mounting cylinders to move horizontally to move closer or further away from each other, so as to assemble the slip ring housing.
