[0023] The utility model will now be described in further detail with reference to the accompanying drawings.

[0024] like Figure 1-7 As shown, a combined power distribution cabinet suitable for steel rolling dephosphorization electricity includes a power distribution cabinet body 3, and two opening and closing door bodies 4 are installed side by side on the front of the power distribution cabinet body 3. The surface of the opening and closing door body 4 is made of transparent material, so that the staff can observe the electrical parts inside the power distribution cabinet body 3 without opening the opening and closing door body 4.

[0025] A locking assembly 1 is installed between the two opening and closing door bodies 4, and the locking assembly 1 is used to control the two opening and closing door bodies 4 to be in a closed state. The locking assembly 1 can effectively avoid the adverse effects caused by leakage of the lock hole; an unlocking assembly 2 is connected below the locking assembly 1, and the unlocking assembly 2 is used to release the lock closure of the opening and closing door bodies 4 by the locking assembly 1.

[0026] The locking assembly 1 includes a mounting column 5 longitudinally mounted between two opening and closing door bodies 4, the backs of the two opening and closing door bodies 4 are fixedly connected with a trapezoidal rod 24, the cross-sectional shape of the trapezoidal rod 24 is a trapezoid, and a lock groove 12 is provided between the two trapezoidal rods 24 on the sides close to each other, a first mounting cavity 7 is provided in the middle of the mounting column 5, and a slide groove 14 is provided on the top wall and the bottom wall of the first mounting cavity 7, and two sliders 13 are clamped inside the two slide grooves 14, and each set of sliders 13 is fixedly connected to a side that is suitable for the lock groove 12 away from each other. A locking block 11 is provided, and a connecting rod 10 is rotatably connected between the mutually adjacent sides of each group of locking blocks 11. A group of lifting blocks 9 are respectively provided at the upper and lower parts of the first installation cavity 7. The other end of each group of connecting rods 10 is rotatably connected to the corresponding lifting block 9. A group of guide rods 15 are fixedly connected to the top and bottom walls of the first installation cavity 7. The lifting block 9 is slidably connected to the corresponding guide rods 15. The guide rods 15 provide guide limits for the up and down movement of the lifting block 9. The locking block 11 can be controlled to move left and right through the up and down movement of the lifting block 9.

[0027] A forward and reverse threaded rod 8 is longitudinally installed in the first installation cavity 7. The two ends of the forward and reverse threaded rod 8 are respectively threadedly connected to the two groups of lifting blocks 9. A fixed block 23 is passed through the middle of the forward and reverse threaded rod 8. The fixed block 23 is fixedly installed on the inner wall of the first installation cavity 7. The forward and reverse threaded rod 8 is used to control the two lifting blocks 9 to move in opposite directions. The fixed block 23 is used to limit the position of the forward and reverse threaded rod 8.

[0028] The threads on the surfaces of the positive and negative threaded rods 8 are symmetrical about the center line of the front surface of the fixed block 23, so that the two lifting blocks 9 can move synchronously when moving up and down.

[0029] When the distribution cabinet body 3 needs to be opened, the staff first rotates the positive and negative threaded rods 8. When the positive and negative threaded rods 8 rotate in the positive direction, the two lifting blocks 9 are guided by the guide rod 15 to move in the direction close to each other. Through the coordinated setting of the connecting rod 10 and the locking block 11, the locking block 11 is subjected to the pulling force of the connecting rod 10, which causes the two groups of locking blocks 11 to move in the direction close to the lifting block 9 respectively. At this time, the locking block 11 will come out of the locking groove 12 and enter the interior of the first installation cavity 7, thereby releasing the locking of the trapezoidal rod 24 by the locking block 11, and the opening and closing door body 4 can be opened at this time; when the distribution cabinet body 3 needs to be closed, the opening and closing door body 4 is first closed, and then the positive and negative threaded rods 8 are rotated in the opposite direction, at this time, the two groups of locking blocks 11 can be moved respectively toward the position close to the locking groove 12, and when the locking block 11 enters the interior of the locking groove 12, the opening and closing door body 4 can be locked, and the distribution cabinet body 3 can be further closed.

[0030] In a preferred embodiment of the utility model, the unlocking component 2 includes a second mounting cavity 16 opened at the lower part of the mounting column 5, the bottom end of the positive and negative threaded rod 8 is fixedly connected to the first rotating rod 17, the first rotating rod 17 passes through the top wall of the second mounting cavity 16 and is rotatably connected to the top wall of the second mounting cavity 16 and the bottom wall of the first mounting cavity 7, the bottom end of the first rotating rod 17 is fixedly connected to the square block 18, the bottom surface of the distribution cabinet body 3 is plugged with a second rotating rod 22, the second rotating rod 22 passes through the bottom wall of the second mounting cavity 16, the top end of the second rotating rod 22 is fixedly connected to the mounting block 19, the diagonal length of the mounting block 19 is less than the width of the second mounting cavity 16, the upper surface of the mounting block 19 is fixedly connected to the square sleeve 20, the square sleeve 20 is adapted to the square block 18, the second rotating rod 22 can drive the mounting block 19 and the square sleeve 20 to move up and down in the second mounting cavity 16, and control the square sleeve 20 to be engaged with the square block 18.

[0031] A spring member 21 is provided between the bottom surface of the mounting block 19 and the bottom wall of the second mounting cavity 16 . The spring member 21 is sleeved on the second rotating rod 22 to support the second rotating rod 22 to prevent the second rotating rod 22 from contacting the ground in normal state.

[0032] The bottom end of the second rotating rod 22 passes through the bottom wall of the distribution cabinet body 3 downward, and a humidity sensor body 26 is fixedly installed on the bottom end of the second rotating rod 22. A plurality of heat dissipation holes 25 are provided on the bottom wall of the distribution cabinet body 3. The heat dissipation holes 25 are used to dissipate heat for electrical components installed inside the distribution cabinet body 3, thereby preventing electrical components inside the distribution cabinet body 3 from malfunctioning due to poor heat dissipation. A magnetic pad 6 is fixedly installed on the front of the mounting column 5, and the magnetic pad 6 is used to seal the gap between the opening and closing door body 4 and the mounting column 5.

[0033] When it is necessary to rotate the forward and reverse threaded rods 8 in forward and reverse directions, the staff only needs to hold the bottom end of the second rotating rod 22 with their hands and then push it upwards. At this time, the mounting block 19 and the square sleeve 20 can be moved toward a position close to the square block 18, and then the square block 18 is embedded in the inside of the square sleeve 20. It is only necessary to rotate the bottom end of the second rotating rod 22 in forward and reverse directions to make the first rotating rod 17 rotate in forward and reverse directions, and then the forward and reverse threaded rods 8 can be rotated synchronously. The spring member 21 is provided to effectively prevent the bottom end of the second rotating rod 22 from contacting the ground.

[0034] In the preferred embodiment of the utility model, in order to facilitate the operation of the staff, a handle is provided at the bottom of the second rotating rod 22, and an open protective cover can be provided around the bottom of the second rotating rod 22. The protective cover is fixedly installed at the bottom of the power distribution cabinet body 3 to protect the humidity sensor body 26. By providing the humidity sensor body 26, when it rains outdoors, after the water on the ground covers the humidity sensor body 26, the humidity sensor body 26 will automatically alarm, so as to gain enough reaction time for the operator to take measures for the whole device in time, so as to avoid excessive rain, and a large amount of rainwater enters the inside of the power distribution cabinet body 3 from the heat dissipation hole 25 to cause irreparable losses.

[0035] A junction box body 27 is fixedly installed on the rear wall inside the distribution cabinet body 3, and a total watt-hour meter body 28 and an ammeter body 29 are respectively installed on the junction box body 27. A surge protector body 32 is fixedly installed in the middle of the front of the junction box body 27, and several air switch bodies 30 are respectively installed on the left and right sides of the front of the junction box body 27, and several sub-watt-hour meter bodies 31 are respectively installed on the left and right sides of the lower part of the front of the junction box body 27.

[0036] Through the junction box body 27 installed inside the distribution cabinet body 3, the purpose of wiring various components inside the distribution cabinet body 3 can be achieved. The total watt-hour meter body 28 and the sub-watt-hour meter body 31 use electronic circuits / chips to measure electric energy, use voltage divider resistors or voltage transformers to convert voltage signals into small signals that can be used for electronic measurement, use shunts or current transformers to convert current signals into small signals that can be used for electronic measurement, use a dedicated electric energy measurement chip to perform analog or digital multiplication on the converted voltage and current signals, and accumulate the electric energy, and then output a pulse signal with a frequency proportional to the electric energy; the pulse signal drives the stepper motor to drive the mechanical meter to measure, or sends it to a microcomputer for processing and digital display. The ammeter body 29 is made according to the effect of magnetic field force on the current-carrying conductor in the magnetic field. When current passes through, the current passes through the magnetic field along the spring and the shaft, and the current cuts the magnetic flux lines. Therefore, under the effect of the magnetic field force, the coil is deflected, driving the shaft and the pointer to deflect. Since the magnitude of the magnetic field force increases with the increase of current, the magnitude of the current can be observed by the degree of deflection of the pointer. The air switch body 30 is also called a low-voltage circuit breaker, which can be used to connect and disconnect load circuits, and can also be used to control infrequently started motors. Its function is equivalent to the sum of some or all functions of electrical appliances such as knife switches, overcurrent relays, undervoltage relays, thermal relays and leakage protectors, and is an important protective appliance in low-voltage distribution networks. The surge protector body 32 is also called a lightning arrester, which is an electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby avoiding damage to other equipment in the circuit caused by the surge.

[0037] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.
