Description

Technical Field

[0001] This utility model relates to the field of fireproof and explosion-proof boxes, and in particular to a fireproof and explosion-proof box for a high-voltage cable connector. Background Technology

[0002] With the continuous development of society, the power system plays an increasingly important role in people's production and daily life. As a key component of power transmission, the safety protection of high-voltage cable joints is crucial. During operation, high-voltage cable joints may experience dangerous situations such as overheating, short circuits, or even explosions due to the thermal effect of current and environmental factors. An explosion can not only cause power outages, affecting industrial production and residential lives, but may also trigger fires, resulting in serious casualties and property damage.

[0003] While existing fireproof and explosion-proof boxes for high-voltage cable joints offer some protection, their limitations are becoming increasingly apparent as power systems become more complex and safety requirements rise. In complex operating environments, such as those caused by earthquakes or strong winds leading to high-intensity vibrations, and in extreme cases, high-energy explosions, current fireproof and explosion-proof boxes struggle to meet the demands in terms of strength and explosion-proof stability. Therefore, we propose a new fireproof and explosion-proof box for high-voltage cable joints to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fireproof and explosion-proof box for high-voltage cable joints.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fireproof and explosion-proof box for high-voltage cable joints includes two boxes, one end of which is connected by a hinge, and the other end of which is connected by a locking mechanism. Multiple honeycomb panels and reinforcing plates are provided on both sides of each box, with adjacent honeycomb panels and reinforcing plates being staggered and fixed. Elastic clamping mechanisms are provided on opposite sidewalls of each box. Through-holes are provided at both ends of each box, with two through-holes on the same side corresponding to each other. These through-holes are connected to the honeycomb panels and reinforcing plates. Foamed aluminum buffer plates are installed on three sidewalls around the perimeter of the box. Sensor groups are installed on both sides of the box.

[0007] Preferably, the locking mechanism includes a connecting plate fixed to one side of the two boxes, the two connecting plates abutting each other, and the connecting plate is provided with three mounting holes, with a bolt passing through two mounting holes on the same side.

[0008] Preferably, the elastic clamping mechanism includes a mounting block fixed between opposite side walls of one of the boxes. Two springs are connected to one side of the mounting block, and an arc-shaped clamping block is connected to one end of each spring. The two arc-shaped clamping blocks on the same side correspond to each other.

[0009] Preferably, the honeycomb plate has a first opening, and the reinforcing plate has a second opening, with the first opening, the second opening, and the through opening on the same side corresponding to each other.

[0010] Preferably, both the honeycomb panel and the reinforcing plate are regular hexagonal structures.

[0011] Preferably, the sensor group consists of a pressure sensor and a temperature sensor.

[0012] In this utility model, when it is needed for use:

[0013] 1. Cable connector installation: First, pass the cable connector through the through-holes at both ends of the box, the first opening on the honeycomb plate, and the second opening on the reinforcing plate in sequence, so that the cable connector is located in the middle of the box for connection. The first opening, the second opening, and the through-hole on the same side correspond to each other to ensure that the cable connector can pass through smoothly.

[0014] 2. Elastic clamping and fixing: After the cable joint is connected, it is clamped and fixed by an elastic clamping mechanism. The mounting block in the elastic clamping mechanism is fixed between the opposite side walls inside the box. One end of the spring connected to one side of the mounting block is connected to the arc-shaped clamping block. The two arc-shaped clamping blocks on the same side correspond to each other under the action of the spring, and elastically clamp the cable joint to ensure the stability of the connection.

[0015] 3. Box snapping and locking: The two boxes connected by hinges are snapped together so that the connecting plates fixed on one side of the two boxes abut against each other. The connecting plates have three mounting holes. Bolts are passed through two mounting holes on the same side to lock the two boxes together.

[0016] 4. Real-time monitoring: The sensor group installed on both sides inside the box starts to work. The sensor group consists of pressure sensors and temperature sensors, which monitor the pressure and temperature changes inside the box in real time. When the pressure or temperature exceeds the normal range, the sensor will send a signal in time to notify the maintenance personnel to take appropriate measures.

[0017] This utility model has the following advantages:

[0018] 1. The honeycomb support structure, composed of hexagonal honeycomb panels and reinforcing plates, is lightweight and high-strength. It can evenly distribute the impact force generated by the explosion to the entire explosion-proof box shell, avoiding excessive local stress that could cause the shell to crack, and greatly improving the overall strength and stability of the explosion-proof box.

[0019] 2. The honeycomb structure increases the utilization rate of the internal space of the explosion-proof box, providing better protection for cable joints;

[0020] 3. Utilizing the excellent energy absorption properties of aluminum foam, when an explosion occurs, the aluminum foam buffer board can absorb the energy generated by the explosion through its own compression deformation, effectively reducing the impact of the explosion on cable joints and the surrounding environment. The aluminum foam buffer board can also play a role in heat insulation and sound insulation, reducing the transmission of heat and noise generated by the explosion, further improving the protective effect.

[0021] 4. The installation of the sensor group enables real-time monitoring of the internal pressure and temperature of the explosion-proof box. By promptly grasping the internal operating status of the box, it can quickly send signals when abnormal pressure or temperature occurs, reminding maintenance personnel to take corresponding measures to prevent the accident from escalating further and improving the safety and reliability of the power system.

[0022] In summary, this invention can evenly distribute the impact force generated by an explosion across the entire explosion-proof box shell, preventing excessive local stress from causing the shell to crack. This greatly improves the overall strength and stability of the explosion-proof box, effectively reduces the impact of the explosion on cable joints and the surrounding environment, and can also quickly send signals when abnormal pressure or temperature occurs, reminding maintenance personnel to take appropriate measures to prevent the accident from escalating further, thus improving the safety and reliability of the power system.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4 A fireproof and explosion-proof box for high-voltage cable joints includes two boxes 12, which are connected at one end by a hinge 15. The hinge allows the two boxes to open and close like a door, facilitating the installation and maintenance of the cable joints.

[0030] The other ends of the two boxes 12 are connected by a locking mechanism. Multiple honeycomb panels 5 and reinforcing plates 7 are provided on both sides of the box 12, and adjacent honeycomb panels 5 and reinforcing plates 7 are fixed in an alternating manner. Elastic clamping mechanisms are provided on the opposite side walls of the box 12. Through holes 8 are provided at both ends of the box 12, and the two through holes 8 on the same side correspond to each other. The through holes 8 are connected to the honeycomb panels 5 and reinforcing plates 7. Foam aluminum buffer plates 10 are installed on the three side walls around the box 12. Sensor groups 14 are installed on both sides of the box 12. The honeycomb structure can evenly distribute the impact force generated by the explosion to the entire explosion-proof box shell, avoiding excessive local stress that could cause the shell to crack. At the same time, the honeycomb structure can also increase the utilization rate of the internal space of the explosion-proof box and provide better protection for cable joints.

[0031] The locking mechanism includes a connecting plate 11 fixed on one side of the two boxes 12. The two connecting plates 11 abut against each other. The connecting plate 11 is provided with three mounting holes 9. A bolt 13 passes through the two mounting holes 9 on the same side. Through the cooperation of the bolt 13 and the mounting holes 9, the two boxes 12 can be firmly locked together to prevent the boxes from opening accidentally during use.

[0032] The elastic clamping mechanism includes a mounting block 6 fixed between opposite side walls inside one of the housings 12. Two springs 2 are connected to one side of the mounting block 6, and an arc-shaped clamping block 1 is connected to one end of each spring 2. The two arc-shaped clamping blocks 1 on the same side correspond to each other. The elastic action of the springs 2 enables the arc-shaped clamping blocks 1 to adaptively adjust according to the size and shape of the cable connector, providing a stable and uniform clamping force to ensure the stability of the cable connector inside the housing.

[0033] The honeycomb panel 5 has a first opening 3 and the reinforcing plate 7 has a second opening 4. The first opening 3, the second opening 4 and the through opening 8 on the same side correspond to each other. Foamed aluminum has good energy absorption performance. When an explosion occurs, the foamed aluminum buffer layer can absorb the energy generated by the explosion through its own compression deformation, reducing the impact of the explosion on the cable joint and the surrounding environment. The foamed aluminum buffer layer can also play the role of heat insulation and sound insulation, reducing the spread of heat and noise generated by the explosion.

[0034] Both the honeycomb panel 5 and the reinforcing plate 7 are regular hexagonal structures. Regular hexagonal structures have good stability and mechanical properties, which can effectively disperse pressure and enhance the structural strength inside the box.

[0035] Sensor group 14 consists of pressure sensors and temperature sensors. High-precision pressure sensors and temperature sensors are installed inside the explosion-proof box to monitor the pressure and temperature changes inside the explosion-proof box in real time. When the pressure or temperature exceeds the normal range, the sensors will send a signal in time to notify the maintenance personnel to take appropriate measures.

[0036] In this utility model, when it is needed for use:

[0037] 1. Cable connector installation: First, pass the cable connector through the through-holes 8 at both ends of the box 12, the first opening 3 on the honeycomb plate 5, and the second opening 4 on the reinforcing plate 7 in sequence, so that the cable connector is located in the middle of the box 12 for connection. The first opening 3, the second opening 4, and the through-hole 8 on the same side correspond to each other to ensure that the cable connector can pass through smoothly.

[0038] 2. Elastic clamping and fixing: After the cable joint is connected, it is clamped and fixed by an elastic clamping mechanism. The mounting block 6 in the elastic clamping mechanism is fixed between the opposite side walls inside the box 12. One end of the spring 2 connected to one side of the mounting block 6 is connected to the arc-shaped clamping block 1. The two arc-shaped clamping blocks 1 on the same side correspond to each other under the action of the spring 2 to elastically clamp the cable joint and ensure the stability of the connection.

[0039] 3. Box snapping and locking: The two boxes 12 connected by hinge 15 are snapped together, so that the connecting plate 11 fixed on one side of the two boxes 12 abuts against each other. The connecting plate 11 is provided with three mounting holes 9. The bolt 13 is passed through two mounting holes 9 on the same side to lock the two boxes 12.

[0040] 4. Real-time monitoring: The sensor group 14 installed on both sides inside the box 12 starts to work. The sensor group 14 consists of pressure sensors and temperature sensors, which monitor the pressure and temperature changes inside the box 12 in real time. When the pressure or temperature exceeds the normal range, the sensor will send a signal in time to notify the maintenance personnel to take corresponding measures.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
