Description
Technical Field
[0001] The present invention relates to the technical field of DC resistance testing, and specifically to a DC resistance testing device based on intelligent heat dissipation in the internal environment. Background Art
[0002] A DC resistance testing device is an intelligent instrument specifically used to measure the DC resistance of inductive devices such as transformers, motors, and current transformers. It can measure various inductive loads, compensate for the current inertia of large inductance devices, and quickly make the test current reach a stable value. It is an essential instrument for systems such as power, water conservancy, railways, metallurgy, coal mines, and chemical industries, as well as manufacturers of transformers, motors, etc. The self-check and automatic calibration functions reduce the difficulty of instrument use and maintenance, and it is an ideal device for measuring the DC resistance of transformer windings and high-power inductance devices.
[0003] During the detection process of existing DC resistance testing devices, the internal electrical components will cause a sudden increase in temperature during operation, resulting in an increase in the internal temperature of the DC resistance testing device. However, the existing DC resistance testing devices do not have an intelligent heat dissipation function and cannot be automatically adjusted according to the change in the internal temperature of the DC resistance testing device, thus affecting the heat dissipation effect of the DC resistance testing device. Summary of the Invention
[0004] The purpose of the present invention is to provide a DC resistance testing device based on intelligent heat dissipation in the internal environment to solve the problems raised in the above background art.
[0005] To solve the above technical problems, the present invention provides the following technical solution: A DC resistance testing device based on intelligent heat dissipation in the internal environment, the DC resistance testing device based on intelligent heat dissipation in the internal environment includes a resistance testing main body. A heat dissipation chamber is provided inside the resistance testing main body. An air inlet is provided on one side of the heat dissipation chamber, and a heat dissipation hole is provided on the other side. A fan is installed at the port of the air inlet. A temperature sensor is installed inside the heat dissipation chamber. A touch switch and a fixed rod are installed on the fan. An electromagnet is installed on the fixed rod. The electromagnet is connected to the resistance testing main body through a wire. A sliding plate is slidably installed on the fixed rod. The sliding plate is connected to the fan through a support spring. A magnetic block is installed on the sliding plate. A pressing block is installed at the bottom of the magnetic block. When the resistance testing main body conducts detection, the resistance testing main body makes the electromagnet operate through a wire, so that the magnetic block adsorbed on the electromagnet can drive the pressing block to move downward under the repulsive force to contact the touch switch, thereby making the fan operate, facilitating the cooling air flow to absorb heat in the heat dissipation chamber and then discharge it through the heat dissipation hole. At the same time, the internal temperature of the resistance testing main body is monitored through the temperature sensor, so as to control the operating power of the fan and facilitate intelligent heat dissipation according to the temperature inside the resistance testing main body.
[0006] As a preferred technical solution, in the initial state, the electromagnet is adsorbed to the magnetic block. When the electromagnet is in the energized state, the magnetic field formed by the electromagnet repels the magnetic block, realizing that the pressing block continuously presses the touch switch, facilitating the self-operation of the magnetic block according to the operating state of the DC resistance testing device.
[0007] As a preferred technical solution, the temperature sensor is electrically connected to the blower. A plurality of sets of refrigeration chips are installed in the air inlet, and the temperature sensor is electrically connected to the refrigeration chips. While the temperature sensor monitors the internal temperature of the DC resistance testing device, the temperature sensor can correspondingly adjust the refrigeration temperature of the refrigeration chips according to the temperature.
[0008] As a preferred technical solution, an air flow primary utilization component and an air flow secondary utilization component are provided on the resistance testing main body, and the blower provides the operating driving force for the air flow primary utilization component and the air flow secondary utilization component.
[0009] As a preferred technical solution, the air flow primary utilization component includes a volute, a rotating shaft, fan plates, an air inlet pipe, a return air pipe, and a transmission bevel gear;
[0010] The volute is installed on the resistance testing main body. The rotating shaft is rotatably installed in the volute. A plurality of sets of fan plates are circumferentially installed on the rotating shaft. The input end of the volute is connected to the output end of the blower through the air inlet pipe, and the output end of the volute is connected to the input end of the blower through the return air pipe. A transmission bevel gear is installed at the end of the rotating shaft. When the blower operates, through the air flow channel formed by the volute, the air inlet pipe, and the return air pipe, while not affecting the air supply efficiency of the blower, the pushing effect of the wind force on the fan plates can be utilized to make the fan plates drive the rotating shaft to rotate, so that the rotating shaft can drive the transmission bevel gear to rotate synchronously.
[0011] As a preferred technical solution, the air flow primary utilization component further includes a cylinder body, a reciprocating lead screw, a driven bevel gear, a moving block, a connecting block, a transmission plate, a rotating hole, a rotating column, a blade plate, a turntable, a traction plate, and a connecting shaft;
[0012] A cylinder block is installed on the resistor test body. A reciprocating lead screw is rotatably installed on the cylinder block. A driven bevel gear is installed at the top of the reciprocating lead screw. The driven bevel gear meshes with a driving bevel gear. A moving block is slidably installed on the reciprocating lead screw. A connecting block is installed on the moving block. A transmission plate is installed on the connecting block. Two sets of rotating holes are provided in the heat dissipation chamber. A rotating column is rotatably installed in the rotating hole. A blade is installed at one end of the rotating column, and a turntable is installed at the other end of the rotating column. A connecting shaft is eccentrically installed on the turntable. The connecting shaft is connected to the transmission plate through a traction plate. When the driving bevel gear rotates, the driving bevel gear can drive the reciprocating lead screw to rotate synchronously through the driven bevel gear. Using the lead screw-nut pair formed by the reciprocating lead screw and the moving block, the longitudinal reciprocating movement of the moving block on the reciprocating lead screw can be realized. When the moving block moves upward, the moving block can drive the transmission plate to move synchronously through the connecting block. During the upward movement of the transmission plate, the transmission plate can drive the turntable to rotate a half cycle through the traction plate. During the rotation of the turntable, the turntable can drive the blade to rotate in the heat dissipation chamber through the rotating column, which is beneficial to the blade to disperse the cooling air flow in the heat dissipation chamber and can increase the flow time of the cooling air flow in the heat dissipation chamber.
[0013] As a preferred technical solution, the two sets of traction plates are in an "eight" shape, which can realize the mutual reverse rotation of the two sets of blades during the movement of the transmission plate. One end of the traction plate is hinged to the transmission plate, and a connecting hole is provided at the other end of the traction plate. The connecting shaft passes through the connecting hole and is in rotational fit.
[0014] As a preferred technical solution, the air flow secondary utilization component includes a piston plate, a linkage rod, a sliding hole, an annular pipe, an air suction head, an air pipe and a one-way air valve;
[0015] A piston plate is slidably installed in the cylinder block. A linkage rod is installed on the piston plate. A sliding hole is provided at the top of the cylinder block. The linkage rod passes through the sliding hole and is connected to the moving block. An annular pipe is installed at the port of the heat dissipation hole. Air suction heads are symmetrically arranged on the annular pipe. The annular pipe is connected to the input end of the cylinder block through an air pipe. A one-way air valve is installed at the output end of the cylinder block. When the moving block moves upward, the moving block can drive the piston plate to move upward synchronously in the cylinder block through the linkage rod. Using the "negative pressure" formed by the upward movement of the piston plate in the cylinder block, the cylinder block can absorb the air flow at the heat dissipation hole through the air pipe and the air suction heads on the annular pipe, so as to form a suction force at the heat dissipation hole and ensure that the air flow carrying heat in the heat dissipation chamber quickly escapes from the heat dissipation hole. When the moving block moves downward, using the "extrusion" force formed by the downward movement of the piston plate in the cylinder block, the hot air flow absorbed in the cylinder block can be discharged from the one-way air valve.
[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:
[0017] When the resistance test main body conducts detection, the resistance test main body makes the electromagnet operate through a wire, so that the magnetic block adsorbed on the electromagnet can drive the pressing block to move downward under the repulsive force to contact the touch switch, thereby making the fan operate, facilitating the cooling air flow to absorb heat in the heat dissipation chamber and then discharge it through the heat dissipation holes. At the same time, the internal temperature of the resistance test main body is monitored through a temperature sensor, so as to control the operating power of the fan and facilitate intelligent heat dissipation according to the temperature inside the resistance test main body.
[0018] Utilize the longitudinal reciprocating movement of the moving block on the reciprocating screw rod. When the moving block moves upward, the moving block can drive the transmission plate to perform synchronous displacement through the connecting block. During the upward movement of the transmission plate, the transmission plate can drive the turntable to rotate a half cycle through the traction plate. During the rotation of the turntable, the turntable can drive the blade to rotate in the heat dissipation chamber through the rotating column, which is beneficial to the blade to disperse the cooling air flow in the heat dissipation chamber and can increase the flow time of the cooling air flow in the heat dissipation chamber.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0032] Embodiment: As Figures 1-5As shown in the figure, the present invention provides the following technical solution: a DC resistance testing device based on intelligent heat dissipation in the internal environment. The DC resistance testing device based on intelligent heat dissipation in the internal environment includes a resistance testing main body 1. A heat dissipation chamber 2 is provided inside the resistance testing main body 1. An air inlet 3 is opened on one side of the heat dissipation chamber 2, and a heat dissipation hole 4 is opened on the other side. A fan 5 is installed at the port of the air inlet 3. A temperature sensor 6 is installed inside the heat dissipation chamber 2. A touch switch 7 and a fixed rod 8 are installed on the fan 5. An electromagnet 9 is installed on the fixed rod 8. The electromagnet 9 is connected to the resistance testing main body 1 through a wire 10. A sliding plate 11 is slidably installed on the fixed rod 8. The sliding plate 11 is connected to the fan 5 through a support spring 12. A magnetic block 13 is installed on the sliding plate 11. A pressing block 14 is installed at the bottom of the magnetic block 13. When the resistance testing main body 1 performs detection, the resistance testing main body 1 makes the electromagnet 9 operate through the wire 10, so that the magnetic block 13 adsorbed on the electromagnet 9 can drive the pressing block 14 to move downward to contact the touch switch 7 under the repulsive force, thereby making the fan 5 operate, facilitating the cooling air flow to absorb heat in the heat dissipation chamber 2 and then discharging it through the heat dissipation hole 4. At the same time, the internal temperature of the resistance testing main body 1 is monitored through the temperature sensor 6, so as to control the operating power of the fan 5 and facilitate intelligent heat dissipation according to the temperature inside the resistance testing main body 1.
[0033] In the initial state, the electromagnet 9 is adsorbed to the magnetic block 13. When the electromagnet 9 is in the energized state, the magnetic field formed by the electromagnet 9 repels the magnetic block 13, realizing that the pressing block 14 continuously presses the touch switch 7, facilitating the self-operation of the magnetic block 13 according to the operating state of the DC resistance testing device.
[0034] The temperature sensor 6 is electrically connected to the fan 5. A plurality of refrigeration sheets 15 are installed inside the air inlet 3. The temperature sensor 6 is electrically connected to the refrigeration sheets 15. While monitoring the internal temperature of the DC resistance testing device through the temperature sensor 6, the temperature sensor 6 can correspondingly adjust the refrigeration temperature of the refrigeration sheets 15 according to the temperature.
[0035] An air flow primary utilization component 16 and an air flow secondary utilization component 17 are provided on the resistance testing main body 1. The fan 5 provides the operating driving force for the air flow primary utilization component 16 and the air flow secondary utilization component 17.
[0036] As Figures 1-8 shown, the air flow primary utilization component 16 includes a volute 1601, a rotating shaft 160, a fan plate 1603, an air inlet pipe 1604, a return air pipe 1605, and a transmission bevel gear 1606;
[0037] A volute 1601 is installed on the resistor test main body 1. A rotating shaft 1602 is rotatably installed in the volute 1601. A plurality of groups of fan plates 1603 are circumferentially installed on the rotating shaft 1602. The input end of the volute 1601 is connected to the output end of the fan 5 through an air inlet pipe 1604. The output end of the volute 1601 is connected to the input end of the fan 5 through a return air pipe 1605. A transmission bevel gear 1606 is installed at the end of the rotating shaft 1602. When the fan 5 operates, through the air flow channel formed by the volute 1601, the air inlet pipe 1604 and the return air pipe 1605, while not affecting the air supply efficiency of the fan 5, the pushing effect of the wind force on the fan plates 1603 can make the fan plates 1603 drive the rotating shaft 1602 to rotate, so that the rotating shaft 1602 can drive the transmission bevel gear 1606 to rotate synchronously.
[0038] The air flow primary utilization component 16 further includes a cylinder block 1607, a reciprocating lead screw 1608, a driven bevel gear 1609, a moving block 1610, a connecting block 1611, a transmission plate 1612, a rotating hole 1613, a rotating column 1614, a blade plate 1615, a turntable 1616, a traction plate 1617 and a connecting shaft 1618;
[0039] A cylinder block 1607 is installed on the resistance test body 1. A reciprocating lead screw 1608 is rotatably installed on the cylinder block 1607. A driven bevel gear 1609 is installed at the top of the reciprocating lead screw 1608. The driven bevel gear 1609 meshes with a driving bevel gear 1606. A moving block 1610 is slidably installed on the reciprocating lead screw 1608. A connecting block 1611 is installed on the moving block 1610. A transmission plate 1612 is installed on the connecting block 1611. Two sets of rotating holes 1613 are formed in the heat dissipation chamber 2. A rotating column 1614 is rotatably installed in the rotating hole 1613. A blade 1615 is installed at one end of the rotating column 1614, and a turntable 1616 is installed at the other end of the rotating column 1614. A connecting shaft 1618 is eccentrically installed on the turntable 1616. The connecting shaft 1618 is connected to the transmission plate 1612 through a traction plate 1617. When the driving bevel gear 1606 rotates, the driving bevel gear 1606 can drive the reciprocating lead screw 1608 to rotate synchronously through the driven bevel gear 1609. By using the lead screw-nut pair formed by the reciprocating lead screw 1608 and the moving block 1610, the longitudinal reciprocating movement of the moving block 1610 on the reciprocating lead screw 1608 can be realized. When the moving block 1610 moves upward, the moving block 1610 can drive the transmission plate 1612 to move synchronously through the connecting block 1611. During the upward movement of the transmission plate 1612, the turntable 1616 can be driven to rotate by a half cycle through the traction plate 1617. During the rotation of the turntable 1616, the blade 1615 can be driven to rotate in the heat dissipation chamber 2 through the rotating column 1614, which is beneficial to the blade 1615 to disperse the cooling air flow in the heat dissipation chamber 2 and can increase the flow time of the cooling air flow in the heat dissipation chamber 2.
[0040] The two sets of traction plates 1617 are in a "V" shape, which can realize the reverse rotation of the two sets of blades 1615 during the movement of the transmission plate 1612. One end of the traction plate 1617 is hinged to the transmission plate 1612. A connecting hole 1619 is formed at the other end of the traction plate 1617. The connecting shaft 1618 passes through the connecting hole 1619 and is in rotational fit.
[0041] As Figures 2-5 and Figures 7-8 shown, the air flow secondary utilization component 17 includes a piston plate 1701, a linkage rod 1702, a sliding hole 1703, an annular pipe 1704, a suction head 1705, an air pipe 1706 and a one-way air valve 1707;
[0042] A piston plate 1701 is slidably installed in the cylinder block 1607. A linkage rod 1702 is installed on the piston plate 1701. A sliding hole 1703 is formed at the top of the cylinder block 1607. The linkage rod 1702 passes through the sliding hole 1703 and is connected to the moving block 1610. An annular pipe 1704 is installed at the port of the heat dissipation hole 4. Suction heads 1705 are symmetrically arranged on the annular pipe 1704. The annular pipe 1704 is connected to the input end of the cylinder block 1607 through an air pipe 1706. A one-way air valve 1707 is installed at the output end of the cylinder block 1607. When the moving block 1610 moves upward, the moving block 1610 can drive the piston plate 1701 to move upward synchronously in the cylinder block 1607 through the linkage rod 1702. By using the "negative pressure" formed by the upward movement of the piston plate 1701 in the cylinder block 1607, the cylinder block 1607 can absorb the air flow at the heat dissipation hole 4 through the air pipe 1706 and the suction heads 1705 on the annular pipe 1704, so as to form a suction force at the heat dissipation hole 4, which can ensure that the air flow carrying heat in the heat dissipation chamber 2 quickly escapes from the heat dissipation hole 4. When the moving block 1610 moves downward, by using the "extrusion" force formed by the downward movement of the piston plate 1701 in the cylinder block 1607, the hot air flow absorbed in the cylinder block 1607 can be discharged from the one-way air valve 1707.
[0043] The working principle of the present invention:
[0044] When the resistance test main body 1 conducts a test, the resistance test main body 1 makes the electromagnet 9 operate through the wire 10, so that the magnetic block 13 adsorbed on the electromagnet 9 can drive the pressing block 14 to move downward under the repulsive force to contact the touch switch 7, thereby making the fan 5 operate, facilitating the cooling air flow to absorb heat in the heat dissipation chamber 2 and then discharge it through the heat dissipation hole 4. At the same time, the internal temperature of the resistance test main body 1 is monitored by the temperature sensor 6, so as to control the operating power of the fan 5 and facilitate intelligent heat dissipation according to the temperature in the resistance test main body 1.
[0045] When the fan 5 operates, through the air flow channel formed by the volute 1601, the air inlet pipe 1604 and the air return pipe 1605, while not affecting the air supply efficiency of the fan 5, by using the pushing effect of the wind on the fan plate 1603, the fan plate 1603 can drive the rotating shaft 1602 to rotate, so that the rotating shaft 1602 can drive the transmission bevel gear 1606 to rotate synchronously.
[0046] When the driving bevel gear 1606 rotates, the driving bevel gear 1606 can drive the reciprocating lead screw 1608 to rotate synchronously through the driven bevel gear 1609. By using the lead screw nut pair formed by the reciprocating lead screw 1608 and the moving block 1610, the longitudinal reciprocating movement of the moving block 1610 on the reciprocating lead screw 1608 can be realized. When the moving block 1610 moves upward, the moving block 1610 can drive the transmission plate 1612 to move synchronously through the connecting block 1611. During the upward movement of the transmission plate 1612, the transmission plate 1612 can drive the turntable 1616 to rotate a half cycle through the traction plate 1617. During the rotation of the turntable 1616, the turntable 1616 can drive the blade 1615 to rotate in the heat dissipation chamber 2 through the rotating column 1614, which is beneficial to the blade 1615 to disperse the cooling air flow in the heat dissipation chamber 2 and can increase the flow time of the cooling air flow in the heat dissipation chamber 2.
[0047] When the moving block 1610 moves upward, the moving block 1610 can drive the piston plate 1701 to move upward synchronously in the cylinder block 1607 through the linkage rod 1702. By using the "negative pressure" formed by the upward movement of the piston plate 1701 in the cylinder block 1607, the cylinder block 1607 can absorb the air flow at the heat dissipation hole 4 through the suction head 1705 on the air pipe 1706 and the annular pipe 1704, so as to form a suction force at the heat dissipation hole 4, which can ensure that the air flow carrying heat in the heat dissipation chamber 2 quickly escapes from the heat dissipation hole 4. When the moving block 1610 moves downward, by using the "extrusion" force formed by the downward movement of the piston plate 1701 in the cylinder block 1607, the hot air flow absorbed in the cylinder block 1607 can be discharged from the one-way air valve 1707.
