Abstract
Description
Technical Field
[0001] This invention relates to the field of distribution box manufacturing, and more specifically to an oil extraction distribution box. Background Technology
[0002] Whether in the construction or machinery industry, distribution boxes are commonly used protective devices for circuit components (circuit breakers, relays, etc.). Existing distribution boxes have two functions: one is to fix and support circuit components, and the other is to protect circuit components.
[0003] With the development of technology, some types of existing distribution boxes have fireproof functions. The fire extinguishing method used in existing distribution boxes is to spray flame-retardant powder inside the closed distribution box. The rapid diffusion of the flame-retardant powder reduces the air density inside the distribution box, thereby achieving the purpose of extinguishing the fire.
[0004] However, during normal use of the distribution box, some workers may neglect to completely close the box door due to negligence. This prevents the box from becoming a truly enclosed space, allowing outside air to easily enter. In this situation, if a fire source appears inside the box and the fire extinguishing system is activated, the fire will not be effectively extinguished. Furthermore, distribution boxes used in oil extraction are prone to flammable gases entering and causing combustion. Therefore, a new type of distribution box for oil extraction needs to be designed to address these issues. Summary of the Invention
[0005] This invention provides an oil extraction power distribution box, the purpose of which is to improve the heat dissipation efficiency of the power distribution box and prevent the power distribution box from exploding.
[0006] The above objectives are achieved through the following technical solutions:
[0007] An oil extraction distribution box, characterized in that: it includes a sliding shell, a box body is slidably connected inside the sliding shell, a baffle I is fixedly connected to the front side of the box body, and a baffle II is fixedly connected to the baffle I; a mounting plate I is fixedly connected to the rear side of the sliding shell, an outer shell I is fixedly connected to the front side of the mounting plate I, and a mounting plate II is fixedly connected to the front side of the outer shell I; four screws are rotatably connected between the mounting plate I and the mounting plate II, and four screw cylinders are fixedly connected to the baffle II, with each screw threaded into the corresponding screw cylinder.

[0013] A mounting plate IV is fixedly connected to the inner side of the outer casing II. A motor is fixedly connected to the mounting plate IV. The output shaft of the motor passes through the mounting plate IV and is fixedly connected to a gear located at the upper right.
[0014] A support plate is fixed to the inner side of the inner door, and a support plate is rotatably connected to the support plate; two rotating shafts II are rotatably connected to the box body; a mounting plate III is fixed to the rear of the mounting plate I, and two sets of brackets are fixed to the left and right sides of the mounting plate III respectively, with a rotating cylinder rotatably connected between each set of brackets.

[0017] The beneficial effects of the oil extraction power distribution box of the present invention are as follows:
[0018] Compared to traditional distribution boxes, this invention features a submersible enclosure that completely isolates the enclosure from external gases, preventing flammable gases from entering. The invention also includes inner and outer doors; when the enclosure is moved outwards so that the inner door is fully against the outer door, both doors can be opened simultaneously to allow for maintenance of the electrical meters inside the enclosure while preventing water from entering. Furthermore, the invention incorporates a sealing cloth that allows gases to escape from the enclosure when the inner door is closed, further reducing the possibility of internal combustion.

Detailed Implementation
[0032] See Figure 1-5 A schematic diagram of an embodiment of the present invention, in which the housing 101 is driven to move back and forth by the screw 109, is shown. Further,
[0033] A housing 101 is slidably connected inside the sliding shell 105. A baffle I 102 is fixedly connected to the front side of the housing 101, and a baffle II 103 is fixedly connected to the baffle I 102. A mounting plate I 106 is fixedly connected to the rear side of the sliding shell 105. A housing I 107 is fixedly connected to the front side of the mounting plate I 106, and a mounting plate II 108 is fixedly connected to the front side of the housing I 107. Four screws 109 are rotatably connected between the mounting plate I 106 and the mounting plate II 108. Four screw cylinders 104 are fixedly connected to the baffle II 103, and each screw 109 is threaded into the corresponding screw cylinder 104.
[0034] The sliding shell 105 can restrict the movement direction of the housing 101, and the housing 101 can provide an installation position for the baffle I 102 and the baffle II 103; by rotating the four screws 109 at the same time, the four screw cylinders 104 can be driven to move forward or backward at the same time, thereby driving the housing 101 to move back and forth.
[0035] See Figure 1-6 A schematic diagram of an embodiment in which the inner side of the outer shell I 107 forms a cavity I according to the present invention is shown. Further,
[0036] Two inner doors 201 are slidably connected to the baffle I 102, and the mounting plate II 108 is provided with an opening that allows the two inner doors 201 to pass through; the upper and lower sides of the mounting plate II 108 are respectively fixed with slide rails 206, and two outer doors 203 are slidably connected between the two slide rails 206.
[0037] The mounting plate I 106, mounting plate II 108, housing 101, sliding shell 105, outer shell I 107, inner door 201, and outer door 203 together form cavity I. Cavity I is used to hold water and can seal the inner housing 101. At the same time, it can cool the inside of housing 101 and prevent overheating.
[0038] See Figure 1-6 A schematic diagram of an embodiment of the opening and closing of the inner door 201 and the outer door 203 according to the present invention is shown. Further,
[0039] A slider 202 is fixedly connected to the inner door 201, and a groove 204 is provided on the inner side of the outer door 203, in which the slider 202 can be slidably connected; a handle 205 is fixedly connected to the outer side of each outer door 203.
[0040] When the housing 101 moves forward, the inner door 201 can completely fit inside the outer door 203, and the slider 202 can slide and connect to the corresponding slide groove 204, so that the inner door 201 and the outer door 203 can move together. At this time, by pulling the two outer doors 203 to the left and right sides with the handle 205, the two inner doors 201 are opened, allowing the inside of the housing 101 to be exposed, so that the internal meter 301 can be repaired, read, or replaced. At the same time, the housing 101 slides outward and fits against the front mounting plate II 108, so that the cavity I remains closed, preventing water from leaking out.
[0041] See Figure 1-11 A schematic diagram of an embodiment of the cooperation between the electric clamp 302 and the wire 303 according to the present invention is shown. Further,
[0042] Multiple meters 301 are installed on the rear side of the housing 101, and an electric clamp 302 is fixedly connected to the rear of each meter 301; multiple wires 303 are fixedly connected to the rear side of the sliding shell 105, and each electric clamp 302 can form a circuit connection with the corresponding wire 303.
[0043] When the housing 101 moves forward, the clamp 302 separates from the wire 303, thereby de-energizing each meter 301 to prevent electric shock during repair and to prevent flammable gases from entering the housing 101 and causing internal combustion. When the housing 101 moves inward, the clamp 302 and the wire 303 come into contact, the circuit is connected, and each meter 301 starts to work.
[0044] See Figure 1-11 This shows a schematic diagram of an embodiment in which the ventilation unit 403 ventilates the interior of the outer casing II 401 according to the present invention. Further,
[0045] The rear side of the mounting plate I106 is fixedly connected to the outer shell II401, the rear side of the outer shell II401 is fixedly connected to the back plate 402, and the top of the outer shell II401 is fixedly connected to the air exchanger 403.
[0046] Mounting plate I 106, outer shell II 401 and back plate 402 form cavity II, which is used to fill with gas and is connected to the inside of box 101. The air exchanger 403 can control the gas exchange between cavity II and the outside, and can filter the gas entering cavity II to prevent combustible gas from entering cavity II.
[0047] See Figure 1-10 A schematic diagram of an embodiment of the present invention, in which the motor 408 drives four screws 109 to rotate simultaneously, is shown. Further,
[0048] Each screw 109 passes through mounting plate I 106, and a gear 111 is fixedly connected to each screw 109. A chain 112 is meshed on the four gears 111. At the same time, mounting plate IV 407 is fixedly connected to the inner side of housing II 401. A motor 408 is fixedly connected to mounting plate IV 407. The output shaft of motor 408 passes through mounting plate IV 407 and is fixedly connected to gear 111 located in the upper right corner.
[0049] The motor 408 can drive the gear 111 located in the upper right corner to rotate through the output shaft, and then drive the four gears 111 to rotate simultaneously through the chain 112, thereby causing the four screws 109 to rotate simultaneously, thus driving the housing 101 to move forward or backward.
[0050] See Figure 1-10 A schematic diagram of an installation embodiment of the sealing cloth 504 according to the present invention is shown. Further,
[0051] A support plate 501 is fixedly connected to the inner side of the inner door 201, and a support plate 501 is rotatably connected to the support plate 501; two rotating shafts II 503 are rotatably connected to the housing 101; a mounting plate III 404 is fixedly connected to the rear of the mounting plate I 106, and two sets of brackets 405 are fixedly connected to the left and right sides of the mounting plate III 404 respectively, with a rotating cylinder 406 rotatably connected between each set of brackets; at the same time, sealing cloths 504 are fixedly connected to the inner sides of the two inner doors 201 respectively, and each sealing cloth 504 is sequentially rolled and connected to the corresponding rotating shaft I 502 and rotating shaft II 503, with both sealing cloths 504 passing through the housing 101 and the mounting plate III 404, and both sealing cloths 504 being wrapped around the corresponding rotating cylinder 406; at the same time, a torsion spring is fixedly connected between each rotating cylinder 406 and the corresponding bracket 405.
[0052] The movement trajectory of the sealing cloth 504 is restricted by the rotating shaft I 502, rotating shaft II 503 and rotating cylinder 406; when the two inner doors 201 move inward to close, the sealing cloth 504 moves inward to discharge the gas inside the box 101 to the outside and reduce the residue of external gas inside the box 101; the torsion spring can keep the sealing cloth 504 in a taut state at all times to prevent the sealing cloth 504 from deforming during movement.
