Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and more specifically to a distribution box that facilitates heat dissipation and its usage method. Background Technology

[0002] Distribution boxes are a common type of electrical control equipment used in oilfield production. In many applications within the petroleum and petrochemical industries, large quantities of flammable and explosive gases are present. In such environments, the reliability of the explosion-proof performance of the distribution box is crucial for safe production. Current technology relies on cooling fans to continuously expel hot gases from the distribution box to ensure heat dissipation for the electrical components and electronic equipment inside. However, this ventilation method inevitably introduces flammable and explosive gases from the outside into the distribution box, significantly compromising its explosion-proof performance.

[0003] For example, Chinese Patent Publication No. CN110880697B discloses the following technical solution: Distribution boxes are electrical devices used for power distribution, commonly found in factories and construction sites. However, in dusty working environments, dust easily accumulates inside the distribution box. If the dust concentration is too high, it can cause dust explosions and other safety accidents, posing a significant safety hazard. Furthermore, dust contains a large amount of metal powder, which, if adhering to the wiring inside the distribution box, may cause short circuits, potentially leading to explosions or fires. Currently, there is a distribution box on the market with dust removal capabilities. The brush, which removes dust by rotating, has the following defects in its dust removal process, as discovered by the applicant: Because circuit switches have many gaps, the brush may accidentally trigger the switch during cleaning if it tries to reach deep into these gaps to remove dust, leading to abnormal operation or shutdown of the electrical equipment. This requires operators to manually reset the switch, impacting production. Furthermore, sudden starting or stopping of the equipment can cause injury to personnel operating it. Additionally, brushes are typically made of animal hair or chemical fibers, which are flammable. If the temperature inside the distribution box becomes too high, the brush can easily spontaneously combust, causing a fire.

[0004] The existing technology has the following problems:

[0005] Since brushes are usually made of animal hair or chemical fibers, which are flammable, they are very likely to spontaneously combust if the temperature inside the distribution box is too high, causing a fire. Therefore, improvements are needed. Summary of the Invention

[0016] A further improvement of the technical solution of the present invention is that the shock-absorbing device includes: a fixed block, the top outer wall of the fixed block is fixedly connected to the bottom outer wall of the bracket, a movable rod is hinged to one side outer wall of the fixed block, and a sliding block is fixedly connected to one end of the movable rod.

[0017] A further improvement of the technical solution of the present invention is that: there are two sliding blocks, each of which is hinged to one end of the movable rod and slidably connected to the bottom inner wall of the chassis, and a second spring damper is fixedly connected to one side outer wall of the sliding block.

[0019] A method for using a heat dissipation distribution box includes the following steps: Step 1: External air passes through a filter screen for dust prevention, preventing the intake of dirt from affecting the performance of internal equipment. By rotating a turntable, the first worm gear rotates, which in turn drives the first worm wheel to rotate. The first worm wheel then drives the threaded rod to rotate, which in turn moves the movable plate. The movable plate then moves the clip frame, which engages and disengages the filter screen for easy replacement and installation.

[0020] Step 2: Rotate the movable disc to rotate the second worm gear, which in turn drives the second worm wheel to rotate.

It also buffers and reduces noise from the suction fan's left-right swaying during operation.

[0021] Step 3: By causing the support frame to vibrate and move when the suction fan is running, the support frame moves the fixed block, the fixed block moves the movable rod, the movable rod moves the sliding block, and the sliding block compresses the second spring damper, which plays a certain role in buffering and reducing noise, while avoiding long-term vibration from causing the suction fan parts to loosen and affecting its performance.

[0022] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0023] 1. This invention provides a power distribution box that facilitates heat dissipation. External air is filtered and dust-proofed through a filter screen to prevent the intake of dirt from affecting the performance of internal equipment. By rotating a turntable, the first worm gear rotates, which in turn drives the first worm wheel to rotate. The first worm wheel then drives the threaded rod to rotate, which in turn moves the movable plate. The movable plate then moves the clip frame, which engages and disengages the filter screen for easy replacement and installation.

[0024] 2. This invention provides a power distribution box that facilitates heat dissipation. By rotating the movable disc, the second worm gear rotates, which in turn drives the second worm wheel to rotate. The second worm wheel then drives the bidirectional threaded rod to rotate, which in turn moves the movable frame. The movable frame then moves the first spring damper, which in turn moves the clamping plate. The clamping plate engages and disassembles the suction fan, facilitating its replacement and cleaning. Simultaneously, it buffers and reduces noise from the fan's left-right swaying during operation.

[0025] 3. This invention provides a power distribution box that facilitates heat dissipation. When the suction fan vibrates during operation, the entire support frame vibrates and moves. When the support frame moves, it drives the fixed block to move. The movement of the fixed block drives the movable rod to move. The movement of the movable rod drives the sliding block to move. The movement of the sliding block compresses the second spring damper, which plays a certain role in buffering and reducing noise, while avoiding the phenomenon that long-term vibration will cause the suction fan components to loosen and affect its performance.

[0044] Example 4

[0045] like Figure 1-7As shown, based on embodiments 1-3, the present invention provides a method for using a power distribution box that facilitates heat dissipation. The steps are as follows: Step 1: External air is filtered and dust-proofed by the filter screen 69 to prevent internal contaminants from affecting the performance of internal equipment.

Rotating the movable disc 74 causes the second worm gear 73 to rotate, which in turn drives the second worm wheel 75 to rotate, which in turn drives the bidirectional threaded rod 76 to rotate. The bidirectional threaded rod 76 then moves the movable frame 77. The movable frame 77 moves, causing the first spring damper 78 to move. The first spring damper 78 moves, causing the clamping plate 79 to move. The clamping plate 79 moves to engage and disassemble the suction fan 710, facilitating personnel to replace and clean the suction fan 710. At the same time, it buffers and reduces noise from the left and right swaying of the suction fan 710 during operation. When the suction fan 710 vibrates during operation, the support 71 vibrates and moves as a whole. When the support 71 moves, it drives the fixed block 81 to move. The fixed block 81 moves, causing the movable rod 82 to move. The movable rod 82 moves, causing the sliding block 83 to move. The sliding block 83 moves and presses the second spring damper 84, which plays a certain role in buffering and reducing noise, while preventing long-term vibration from causing the suction fan 710 parts to loosen and affecting performance.
