Detailed Implementation
[0027] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0028] The invention will now be further described with reference to the accompanying drawings.
[0029] like Figure 3 , Figure 4 and Figure 5 To solve the problem of easily replacing the circuit breaker;
[0030] A dustproof and heat-dissipating power distribution cabinet includes multiple plugs 11, a conical groove 101 fixedly connected to the corresponding plug 11, two corresponding contact pieces 102 rotatably connected between each other, and every two contact pieces 102 slidably connected within the conical groove 101. A first compression spring 103 is fixedly connected between the two corresponding contact pieces 102.
[0031] When connecting a circuit breaker, the wire must first be inserted into the circuit breaker interface, and then the screws at the interface must be tightened to press it firmly into the interface, thus ensuring a secure connection between the wire and the circuit breaker contacts at the interface. However, this method requires repeatedly tightening the screws at each interface every time the circuit breaker is replaced, which greatly increases the time spent on circuit breaker replacement and wastes manpower. Furthermore, direct contact with exposed wires during each installation increases the safety risk for workers. In this invention, the circuit breaker is directly installed in a fixed position, and then the four plugs 11 are driven to move towards the interface, thereby moving the conical groove 101, which in turn moves the contacts 102 within the conical groove 101. Initially, the first compression spring 103 is in an extended state. This causes the connector 102 to be wider at the top and narrower at the bottom, making it easier to insert the connector 102 into the interface. When the connector 102 is inserted into the interface, the tapered groove 101 continues to move, thereby tightening the upper end of the connector 102 and pressing the lower end of the connector 102 against the inner wall of the interface. The wire is then passed through the plug 11 and connected to the inner wall of the tapered groove 101, thereby connecting the external circuit to the circuit breaker. When the circuit breaker is removed, the connector 101 has a locking groove at the upper end. Simultaneously, as the plug 11 is moved, the tapered groove 101 moves accordingly, locking the upper end of the connector 101 to prevent it from falling off. At the same time, the compressed first compression spring 103 extends, causing the connector 101 to become wider at the top and narrower at the bottom, making it easier to pull out and thus facilitating the replacement of the circuit breaker.
[0032] like Figure 3 and Figure 6 To facilitate control of plug movement;
[0033] The slide rod 104 is fixedly connected to the other end of the plug 11, and the slide rod 104 is slidably connected to the fixed base 12. The first tension spring 105 is fixedly connected between the plug 11 and the fixed base 12.
[0034] The circuit breaker is installed on the fixed base 12. Initially, the first tension spring 105 is in an extended state, which causes the plug 11 to move away from the circuit breaker. When the circuit breaker is inserted, the first tension spring 105 pulls the plug 11 to move inward, which in turn drives the insert 11 to move into the interface of the circuit breaker.
[0035] like Figure 6 To achieve the goal of simultaneously controlling the slider.
[0036] Each fixed base 12 has two heat dissipation clips 201 slidably connected to it, and a second compression spring 202 is fixed between each pair of corresponding heat dissipation clips 201.
[0037] Initially, the second compression spring 202 is in an extended state, and the two heat dissipation clips 201 are relatively far apart. The heat dissipation clips 201 are provided with an inclined track, and the slide rod 104 is located above the track, so that the plug 11 is located away from the power switch. The first tension spring 105 is in an extended state at the same time. When the power switch is installed on the fixed base 12, the two heat dissipation clips 201 move inward, and the slide rod 104 moves towards the power switch along the inclined track due to the action of the first tension spring 105, thereby achieving the purpose of controlling the slide rod at the same time.
[0038] like Figure 7 and Figure 8 To prevent the circuit breaker from sliding up and down between the heat sink fins;
[0039] Two inserts 13 are slidably connected to the fixed base 12, and the second tension spring 301 is fixed between the corresponding two inserts 13.
[0040] Initially, the second tension spring 301 is in a contracted state, and the two inserts 13 are located in the middle of the fixed base 12. When the switch contacts the fixed base 12, the two inserts 13 move up and down to the sides at the same time, so that they are inserted into the fixed groove on the back of the switch, thereby preventing the switch from moving up and down. Then, the two heat dissipation clips 201 tighten the switch from the left and right sides.
[0041] like Figure 7 and Figure 8 To achieve the goal of simultaneously controlling the movement of the two inserts 13 to both sides;
[0042] The turntable 302 is rotatably connected to the fixed base 12, and each turntable 302 is in contact with the corresponding two inserts 13.
[0043] When the rear end of the switch is about to contact the fixed base 12, the switch continues to move, driving the turntable 302 to rotate. The turntable 302 is elliptical. Initially, the shorter sides contact the insert 13. As the turntable 302 rotates, the distance between the two inserts 13 gradually increases, thereby controlling the two inserts 13 to move to both sides. The thickness of the insert 13 is less than the thickness of the fixed groove behind the switch. When the insert 13 is located in the fixed groove, it is driven to move, thus avoiding the insert 13 from affecting the installation of the switch.
[0044] like Figure 9 In order to achieve the purpose of resetting the control turntable and avoiding affecting the removal of the power switch;
[0045] Spring sheet 304 is fixed between turntable 302 and fixed base 12.
[0046] When the circuit breaker is removed, in order to prevent the insert 13 from obstructing the removal of the circuit breaker, the compressed spring 304 drives the turntable 302 to rotate in the opposite direction when the turntable 302 rotates. As a result, the distance between the two inserts 13 changes from a large diameter to a small diameter. Then, the second tension spring 301 pulls the two inserts 13 to move inward, thereby ensuring that the circuit breaker can be removed smoothly.
[0047] like Figure 8 , Figure 10 and Figure 11 To achieve the purpose of controlling the rotation of the turntable;
[0048] The pressure plate 14 is slidably connected to the fixed base 12. Each pressure plate 14 is fixedly connected to the corresponding fixed base 12 with a third compression spring 402. Each pressure plate 14 is slidably connected to the corresponding turntable 302. Each turntable 13 is provided with two first inclined surfaces 303, and each pressure plate 14 is provided with two corresponding second inclined surfaces 401.
[0049] Pressing the switch moves it toward the fixed base 12. When the insert 13 is in the fixed slot, the switch continues to move and presses the pressure plate 14. Then the second inclined surface 401 contacts the first inclined surface 303, which drives the first inclined surface 303 to rotate, thereby driving the turntable 302 to rotate, thus achieving the purpose of controlling the rotation of the turntable 302. When the switch presses the pressure plate 14 to move, the third pressure spring 402 is compressed. When the switch is removed, the compressed third pressure spring 402 drives the pressure plate 14 to move, and the turntable 302 resets, thus facilitating the installation of the new switch.
[0050] like Figure 6 , Figure 12 and Figure 13 This is to achieve the purpose of heat dissipation inside the distribution cabinet;
[0051] Multiple heat dissipation clips 201 are slidably connected to the heat dissipation platform 15. A housing 501 is fixedly connected to the heat dissipation platform 15. Multiple heat dissipation plates 502 are fixedly connected to the outside of the housing 501. Each heat dissipation plate 502 is fixedly connected to the heat dissipation platform 15.
[0052] After the circuit breaker is installed on the mounting base 12, the circuit breaker is moved forward, which in turn moves the mounting base 12 and the heat dissipation clips 201 toward the heat dissipation platform 15. The heat dissipation clips 201 have arc-shaped protrusions on their outer sides. As the heat dissipation clips 201 move, the heat dissipation platform 15 presses the two heat dissipation clips 201 inward, thereby controlling the heat dissipation clips 201. When removing the circuit breaker, the heat dissipation clips 201 are moved outward first, and then the circuit breaker is moved outward. The heat dissipation platform 15, the heat dissipation clips 201, and the heat dissipation plate 502 are all made of materials with good thermal conductivity, which avoids the heat dissipation clips 201 affecting the heat dissipation effect when they clamp the circuit breaker. Heat can be dissipated from the heat dissipation clips 201 through the heat dissipation platform 15, and at the same time, heat can be dissipated from the heat dissipation plate 502 to the outside of the outer casing 501, further increasing the heat dissipation effect.
[0053] like Figure 1 , Figure 2 and Figure 14 To achieve the purpose of dust prevention inside the distribution cabinet;
[0054] Two sealed rotating doors are rotatably connected to the outer casing 501.
[0055] The outer casing 501 is provided with two dustproof nets, each dustproof net is slidably connected with two brush plates 16, each brush plate 16 is threadedly connected with a threaded rod 601, each threaded rod 601 is rotatably connected to the outer casing 501, and one end of each threaded rod 601 is fixedly connected with a crank handle 602, which is located outside the outer casing 501.
[0056] The sealed rotary door can seal the interior of the housing 501, preventing dust from entering the distribution cabinet through the rotary door. At the same time, rotating the sealed rotary door also facilitates the replacement of the circuit breaker. To ensure the heat dissipation effect inside the housing 501, a dustproof screen is provided on the housing 501. Air can flow through the dustproof screen and pass through the interior of the housing 501, thereby dissipating heat from the internal circuit breaker. To prevent dust and debris from accumulating on the dustproof screen and affecting its heat dissipation effect, the crank handle 602 is turned, which in turn drives the threaded rod 601 to rotate, thereby driving the brush plate 16 to move, thus cleaning the dust on the dustproof screen. At the same time, the crank handle 602 is set on the outside of the housing 501, so that the sealed rotary door does not need to be opened when cleaning dust, thereby further increasing the dustproof effect inside the housing 501.
