The connectors are used to introduce the connectors of the generator cable and the external cable into the housing. A position adjustment component is connected inside the housing, and a connecting end is connected to the position adjustment component. The connecting end is used to connect the connectors of the generator cable and the external cable to each other. A heat dissipation component is connected to the housing, and the heat dissipation component includes a heat dissipation hole connected to the bottom of the housing.

[0039] like Figures 1 to 7As shown, a reliable temperature connection device for a melamine carrier gas generator includes a housing 1 and connectors 2 connected to both sides of the housing 1. The connectors 2 are used to introduce the generator's cable and the connector of an external cable into the housing 1. A position adjustment component 3 is connected inside the housing 1, and a connecting end 4 is connected to the position adjustment component 3. The connecting end 4 is used to connect the generator's cable and the connector of the external cable to each other. A heat dissipation component 5 is connected to the housing 1. The heat dissipation component 5 includes a heat dissipation hole 51 connected to the bottom of the housing 1. The heat dissipation hole 51 is used to exhaust the hot air inside the housing 1.

[0040] In this embodiment, the existing junction boxes are small with numerous thin wires and many connection points, making inspection and maintenance inconvenient and resulting in long maintenance times. This application increases the size of the box 1, optimizes the wiring method, extends the cable connections to a larger explosion-proof enclosure, improves the wiring environment, ensures accurate temperature indication, and guarantees long-term unit operation. The heat sink 5 effectively dissipates heat from the box 1, further enhancing the stability of the unit's operation.

[0041] In some embodiments, the housing 1 has side mounting grooves 11 on both sides, and a wire hole 12 is provided in the middle of the side mounting grooves 11. The connector 2 includes a wire mounting base 21 connected in the side mounting grooves 11 and a wire mounting head 22 threadedly connected to the wire mounting base 21. The wire mounting head 22 and the wire mounting base 21 are used to fix the unit's cables and external cables, and to introduce the unit's cables and external cables into the housing 1 through the wire hole 12.

[0042] In this embodiment, the side mounting groove 11 enables the wiring mounting base 21 to be securely connected to the housing 1. The wiring mounting head 22 ensures that the unit's cables and external cables can avoid poor contact or signal interruption caused by loose cable joints, which is especially suitable for reliable connection under high temperature and high frequency vibration conditions.

[0043] In some embodiments, a mounting screw 6 is connected inside the housing 1, and the mounting screw 6 is threadedly connected to the wiring mounting base 21.

[0044] In this embodiment, the connection between the mounting screw 6 and the wiring mounting base 21 is threaded, which further improves the stability of the wiring mounting base 21 and the housing 1.

[0045] In some embodiments, a rubber seal 23 is connected between the wiring mounting base 21 and the wiring mounting head 22. The rubber seal 23 is used to abut against the unit's cables and external cables to seal them.

[0046] In this embodiment, the rubber seal 23 seals the gaps between the unit's cables and external cables and the wiring mounting base 21 and the wiring mounting head 22, thereby increasing the sealing performance of the connection. Furthermore, this connector is preferably a 304 stainless steel M8*1 gland.

[0047] In some embodiments, the position adjustment member 3 includes an adjustment rail 31 connected within the housing 1 and a sliding block 32 slidably connected to the adjustment rail 31, and the connecting end 4 is connected to the sliding block 32.

[0048] In this embodiment, the sliding connection design between the adjusting track 31 and the sliding block 32 allows the connecting end 4 to move freely along the track direction. By adjusting the position of the sliding block 32 on the adjusting track 31, the joint ends of the unit cable and the external cable can be precisely aligned, eliminating connection stress caused by manufacturing errors or assembly deviations. This is especially suitable for flexible wiring requirements in scenarios where multiple cables are accessed in parallel.

[0049] In some embodiments, the adjustment track 31 is provided with track grooves 33 on both the upper and lower sides, and the sliding block 32 is threadedly connected to locking screws 34 on the upper and lower sides respectively. When the locking screws 34 are in the locked position, they abut against the track grooves 33 to fix the sliding block 32 on the adjustment track 31. When the locking screws 34 are in the unlocked position, they disengage from the track grooves 33, so that the sliding block 32 can slide on the adjustment track 31.

[0050] In this embodiment, the locking screw 34 effectively improves the stability of the sliding block 32, ensuring the stable operation of the equipment during operation.

[0051] In some embodiments, the heat dissipation component 5 includes a sealing slide rod 52 connected inside the housing 1 and a sealing block 53 slidably connected to the sealing slide rod 52. The sealing block 53 is disposed directly above the heat dissipation through hole 51. When the sealing position is closed, the sealing block 53 abuts against the heat dissipation through hole 51 to seal the heat dissipation through hole 51. When the sealing position is open, the sealing block 53 is away from the heat dissipation through hole 51, allowing gas to flow through the heat dissipation through hole. An upper fixing seat 54 is connected to the sealing slide rod 52, and a telescopic motor 55 is connected to the upper fixing seat 54. The telescopic end of the telescopic motor 55 is connected to the sealing block 53.

[0052] In this embodiment, the existing technology suffers from poor sealing between the junction box and the unit, leading to the introduction of sealing gas lubricating oil into the junction box. This results in poor contact at the wiring points, large temperature fluctuations, and ultimately, interlocking shutdowns, impacting production and causing significant losses to the company's production efficiency. This application solves the sealing problem between the junction box and the unit using the sealing block 53, enabling explosion-proof installation of the device.

[0053] In some embodiments, the bottom of the inner cavity of the box body 1 is provided with a drainage groove 13 and a sealing groove 14 provided on the heat dissipation through hole 51, and the shape of the sealing groove 14 corresponds to the shape of the sealing block 53.

[0054] In this embodiment, the drainage groove 13 is used to collect oil in the case of oil in the housing 1, and the oil can be discharged through the heat dissipation hole 51. At the same time, the height of the heat dissipation hole 51 in the vertical plane is lower than the height of the drainage groove 13 in the vertical plane.

[0055] In some embodiments, a humidity sensor 71 is provided in the drainage groove 13, and a temperature sensor 72 is connected inside the box body 1.

[0056] In some embodiments, a lid 8 is connected to the housing 1, and a display screen 9 is connected to the lid 8. The display screen 9 is used to display the data of the humidity sensor 71 and the temperature sensor 72.

[0057] In this embodiment, humidity sensor 71 and temperature sensor 72 can monitor the actual situation inside the housing 1 and display it on the display screen 9. Operators can discharge heat or oil from inside the housing 1 according to the actual situation. Furthermore, the installation of a fan at the bottom of the housing 1 to improve heat dissipation or drainage speed should also fall within the scope of this application. Since the replacement cost of the fan is low, the lack of protection for the fan is not within the scope of this application.

[0058] Example 1:

[0059] The housing 1 is made of high-temperature resistant and flame-retardant alloy material, with a rectangular structure, possessing good heat insulation and corrosion resistance, and can adapt to the temperature environment around the melamine carrier gas engine. The housing 1 is connected to the housing cover 8 by connecting screws. The edge of the housing cover 8 is equipped with a sealing ring, which fits tightly with the edge of the housing 1 when closed, further enhancing the internal sealing performance.

[0060] The box 1 has symmetrical side mounting grooves 11 on both sides. The inner wall of the groove is machined with internal threads, and a through hole 12 is opened in the middle. The diameter is adapted to the common cable specifications for the introduction of unit cables and external cables. The connector 2 is installed in the side mounting groove 11 and includes a connector mounting base 21, a connector mounting head 22, and a rubber seal 23. The connector mounting base 21 is a stepped cylindrical structure. The outer wall is threaded to the side mounting groove 11, and the rear end is fixed by a mounting screw 6 inside the box 1. The mounting screw 6 passes through the side wall of the box and is threaded to the connector mounting base 21 to prevent vibration and loosening. The connector mounting head 22 is threaded to the front end of the connector mounting base 21. The rubber seal 23 embedded between the two is made of high-temperature resistant silicone. The inner wall has multiple anti-slip ridges. When the cable passes through, tightening the connector mounting head 22 can squeeze the rubber seal 23 to tightly wrap the outer wall of the cable, achieving a seal between the through hole 12 and the cable, and preventing the intrusion of dust, water vapor, and high-temperature airflow.

[0061] A position adjustment component 3 is horizontally fixed in the middle of the inner cavity of the housing 1 to adapt to the connection of cable connectors under different working conditions and ensure connection stability. The position adjustment component 3 includes an adjustment rail 31, a sliding block 32, a rail groove 33, and a locking screw 34. The adjustment rail 31 is a long strip metal rail made of high-strength aluminum alloy. The upper and lower sides are evenly provided with rail grooves 33 along the length direction, and the cross-section is either arc-shaped or inclined. The sliding block 32 is a rectangular slider adapted to the adjustment rail 31. Its cross-section corresponds to the cross-section of the groove. A sliding hole is provided in the middle to fit on the rail, allowing it to slide smoothly along the rail. The front side is fixed to the connecting end 4 by bolts. The upper and lower sides of the sliding block 32 are symmetrically threaded with locking screws 34. The end of the screw is arc-shaped to match the rail groove 33. When tightened, the end is embedded in the groove to form a rigid lock, avoiding position displacement caused by thermal expansion and contraction due to temperature changes. When loosened, it disengages from the groove, allowing flexible adjustment of the position of the connecting end 4.

[0062] The bottom of the box body 1 is equipped with a heat dissipation component 5 to achieve controlled heat dissipation. It includes a heat dissipation through hole 51, a sealing slide rod 52, a sealing block 53, an upper fixing seat 54, and a telescopic motor 55. The heat dissipation through hole 51 is an array of circular holes located at the bottom of the box body to dissipate the heat generated by the cable being energized. The bottom of the inner cavity of the box body 1 is inclined at 5° towards the heat dissipation through hole 51 and has a drainage groove 13 with a V-shaped cross section to guide a small amount of condensate or liquid that seeps in to the vicinity of the through hole, preventing liquid accumulation from affecting the connection. A sealing groove 14 is provided above the heat dissipation through hole 51, which matches the shape of the sealing block 53 to improve the sealing performance.

[0063] The sealing slide rod 52 consists of two parallel high-temperature resistant metal rods, which are vertically fixed to the top of the inner cavity of the box 1 at the position corresponding to the heat dissipation through hole 51. The sealing block 53 is a rectangular block made of high-temperature resistant silicone material, with a sliding hole in the middle that slides and connects to the sealing slide rod 52. The bottom has a sealing flange that matches the sealing groove 14. The upper fixing seat 54 is fixed to the top of the sealing slide rod 52, and a telescopic motor 55 is installed on it. It is a high-temperature resistant servo motor. The telescopic end of the motor is connected to the top of the sealing block 53, which can drive the sealing block 53 to move up and down along the slide rod to open the heat dissipation through hole 51, i.e., the unsealed position or close it, i.e., the sealed position.

[0064] A humidity sensor 71 is embedded at the bottom of the drainage groove 13 to monitor the internal humidity and prevent the influence of condensation; a temperature sensor 72 is fixed on the inner wall of the box body 1 to monitor the internal temperature in real time; a display screen 9 is embedded on the outer surface of the box cover 8. It is a high-temperature resistant LCD screen, which is connected to the sensor through a high-temperature resistant wire and can display the temperature in ℃ and the humidity in %RH data in real time.

[0065] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0066] This application increases the size of the junction box, optimizes the wiring method, extends the cable connection to a larger explosion-proof box, improves the wiring environment, ensures accurate temperature indication, and guarantees long-term unit operation. The heat sink effectively dissipates heat from the junction box, further enhancing the stability of unit operation. It solves the problem of small junction boxes and poor heat dissipation in existing technologies, which led to frequent unit shutdowns.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
