Description

Technical Field

[0001] The invention belongs to the field of electrical technology, and in particular relates to an explosion-proof power supply and a power supply equipment box for testing equipment. Background Art

[0002] The explosion-proof power supply used in the test equipment is a power supply device specially designed to provide stable power in explosive environments. This power supply device has the characteristics of explosion-proof, dustproof, waterproof, etc. It can maintain normal operation in harsh environments and provide reliable power support for the test equipment.

[0003] The design of explosion-proof power supply is mainly for the safe use of electrical equipment in the environment where flammable gas or steam exists. Its core features include the installation of a flameproof box outside the power supply. The function of this flameproof box is to prevent the flame, high temperature and pressure generated by the explosion from spreading to the external environment when an explosion occurs inside, thereby preventing the external flammable gas or steam from being ignited or detonated.

[0004] However, the conventional device still has the following problems when used:

[0005] When using explosion-proof power supplies in the prior art, a special explosion-proof power supply box is usually configured on the outside of the power supply. This design is intended to effectively prevent the expansion of the explosion area that may be caused by the expansion and explosion of the power supply. However, when the power supply explodes inside the closed explosion-proof power supply box, it will inevitably cause the pressure inside the box to rise sharply. Once this internal pressure exceeds the bearing limit of the explosion-proof power supply box, it will easily cause the box to deform, which may in turn affect the overall protection performance and structural integrity of the explosion-proof power supply.

[0006] Therefore, we need a test equipment with an explosion-proof power supply and a power supply equipment box to solve the problem of increased pressure inside the box when the power supply explodes, and to avoid the increase of pressure inside the explosion-proof power supply box.

DETAILED DESCRIPTION

[0031] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] For example, see Figures 1 to 10 The present invention provides a technical solution for an explosion-proof power supply and a power supply equipment box for testing equipment: it includes an explosion-proof power supply body 11, the outer wall of the explosion-proof power supply body 11 is provided with an explosion-proof power supply box body 1, the interior of the explosion-proof power supply box body 1 is provided with a buffer mechanism, one side of the explosion-proof power supply box body 1 is provided with a voltage reduction mechanism, the buffer mechanism includes an elastic sheet 31, the outer wall on one side of the elastic sheet 31 is fixedly connected to the inner wall of the explosion-proof power supply box body 1, the outer wall on the other side of the elastic sheet 31 is fixedly connected to a buffer plate 3, a buffer chamber is provided inside the buffer plate 3, an outer wall on the front side of the buffer plate 3 is provided with an inlet 32, the outer wall on one side of the inlet 32 ​​is through-connected with the outer wall on one side of the buffer chamber, an outer wall on the back side of the buffer plate 3 is provided with an outflow groove, and a push plate 21 is fixedly connected to the back side of the buffer plate 3 at a position aligned with the explosion relief pipe 2.

[0033] When the explosion occurs due to a fault in the explosion-proof power supply body 11, the impact of the explosion enters the buffer chamber on the buffer plate 3 through the inlet 32, and then flows out through the outflow groove. The space in the buffer chamber gradually slows down the impact of the explosion, avoiding the impact from acting on the inner wall of the explosion-proof power supply box body 1 instantly, and correspondingly reducing the damage to the explosion-proof power supply box body 1 caused by the impact;

[0034] The buffer plate 3 is provided to improve the explosion resistance and service life of the explosion-proof power supply box body 1, thereby increasing the safety of the explosion-proof power supply box body 1 and preventing the explosion of the explosion-proof power supply body 11 inside the explosion-proof power supply box body 1. The pressure generated by the explosion can be prevented from rushing out of the explosion-proof power supply box body 1, thereby increasing the stability of the explosion-proof power supply box body 1 accordingly.

[0035] Embodiment 2, on the basis of embodiment 1, the back side of the buffer plate 3 is located above the outflow groove and is fixedly connected to a fixed protective shell 42, track grooves are provided on both sides of the inner wall of the fixed protective shell 42, one end of the inner wall of the two track grooves is fixedly connected to a return spring 43, the outer wall of one end of the return spring 43 is fixedly connected to a slider 44, the outer walls of the two sliders 44 on the opposite side are fixedly connected to a movable protective shell 45, the outer wall of the movable protective shell 45 is slidably connected to the inside of the fixed protective shell 42, one end of the inner wall of the movable protective shell 45 is fixedly connected to a soft baffle 46, a puncture needle 47 is fixedly connected to the middle position inside the fixed protective shell 42, the inner wall of the explosion-proof power supply box body 1 is located between the two elastic sheets 31 and is fixedly connected to a mounting seat 41, the outer wall of one end of the mounting seat 41 is fixedly connected to an airbag 4, and the outer wall of one side of the airbag 4 is in active contact with the outer wall of one end of the puncture needle 47.

[0036] The nitrogen inside the airbag 4 is released, and the nitrogen can dilute the oxygen concentration in the air to below the minimum level where the flame cannot be maintained, thereby playing a fire extinguishing role. When the nitrogen floats inside the explosion-proof power supply box body 1, it can prevent the explosion-proof power supply body 11 from catching fire after the explosion. At the same time, the nitrogen will absorb heat during the release process, so that the temperature of the fire source area will drop rapidly, which helps to extinguish the flame and prevent re-ignition, avoiding the explosion-proof power supply body 11 from catching fire after the explosion, and correspondingly preventing the explosion-proof power supply box body 1 from catching fire after the explosion, thereby reducing the loss caused by the explosion of the explosion-proof power supply body 11 and reducing the cost of maintenance and replacement;

[0037] By setting up the movable protective shell 45 and the soft baffle 46, the puncture needle 47 is protected inside the fixed protective shell 42, so that the puncture needle 47 is prevented from accidentally puncturing the airbag 4 when it is not needed to work, and the nitrogen inside the airbag 4 is released. Correspondingly, a physical barrier is provided for the puncture needle 47, so that it is isolated when it is not needed to work, thereby preventing the risk of the puncture needle 47 accidentally puncturing the airbag 4 and further increasing the stability of the puncture needle 47.

[0038] Embodiment 3, on the basis of embodiment 2, the voltage reduction mechanism includes an explosion-proof pipe 2, a square groove is provided on one side of the outer wall of the explosion-proof power supply box body 1, the interior of the square groove is fixedly connected to the outer wall of the explosion-proof pipe 2, the inner wall of the explosion-proof power supply box body 1 is located on the outer wall of the explosion-proof pipe 2 on one side and a temporary storage groove 29 is provided, the outer wall of the temporary storage groove 29 is connected through the outer wall of the explosion-proof pipe 2, one end of the inner wall of the temporary storage groove 29 is fixedly connected to a third spring 210, the outer wall of one end of the third spring 210 is fixedly connected to an explosion-proof sheet 211, the outer wall of the explosion-proof sheet 211 is slidably connected to the interior of the temporary storage groove 29, a square groove is provided on the outer wall of the other side of the explosion-proof pipe 2, the outer wall of one end of the square groove is fixedly connected to a first spring 23, and the outer wall of one end of the first spring 23 is fixedly connected to a T-shaped fixing rod 2 2. A strip groove is provided on the explosion-proof plate 211. The outer wall of one end of the T-shaped fixing rod 22 is movably plugged into the inside of the strip groove. The outer wall of the T-shaped fixing rod 22 is slidably connected to the inside of the square groove. The outer wall of one side of the T-shaped fixing rod 22 is in movably contact with the outer wall of one end of the push plate 21. A sliding groove 28 is provided on the upper and lower sides of the inner wall of the square groove. A mounting plate 25 is slidably connected to the inside of the sliding groove 28. The outer wall of one side of the mounting plate 25 is fixedly connected to the second spring 24. The outer wall of one end of the second spring 24 is fixedly connected to the other side of the inner wall of the square groove. The inner part of the other side of the mounting plate 25 is fixedly connected to the magnetic plate 1 27. The inner part of one side of the T-shaped fixing rod 22 is fixedly connected to the magnetic plate 212. The outer wall of one side of the magnetic plate 212 is connected to the outer wall of one side of the magnetic plate 1 27 with opposite poles attracting each other.

[0039] By opening the explosion-proof pipe 2, the pressure inside the explosion-proof power supply box body 1 is released, the pressure level inside the explosion-proof power supply box body 1 is reduced, and the damage to the surrounding environment and personnel caused by the explosion is avoided. Accordingly, as the pressure inside the explosion-proof power supply box body 1 is released, the shock wave generated by the explosion will also be alleviated to a certain extent, which helps to reduce the damage to the surrounding environment and personnel caused by the explosion. At the same time, the explosion-proof power supply box body 1 is prevented from rupture and deformation when the pressure inside the explosion-proof power supply box body 1 is too high, further reducing the risk of rupture of the explosion-proof power supply box body 1.

[0040] Embodiment 4, on the basis of embodiment 3, the outer wall of one side of the explosion-proof tube 2 is fixedly connected with a U-shaped limit rod 26, the inner wall of the explosion-proof tube 2 is fixedly connected with a support rod 214, the outer wall of the support rod 214 is rotatably connected with a baffle plate 213, the outer wall on one side of the baffle plate 213 is in active contact with the inner wall of the U-shaped limit rod 26, and the outer wall at the other end of the T-shaped fixed rod 22 is in active contact with the outer wall on the other side of the baffle plate 213.

[0041] By tilting the baffle plate 213 on the explosion-proof pipe 2, the pressure discharged from the explosion-proof pipe 2 is shielded, thereby preventing the pressure discharged through the explosion-proof pipe 2 from being directly ejected and causing safety hazards to the surrounding environment and personnel. Accordingly, the baffle plate 213 is set to change the direction of the pressure and discharge it to the ground through the bottom of the baffle plate 213, thereby preventing the pressure from being directly ejected and causing damage to the surrounding environment.

[0042] The working principle and use process of the present invention are as follows: during use, first, when the explosion-proof power supply body 11 fails and explodes, the impact of the explosion enters the buffer chamber on the buffer plate 3 through the inlet 32, and then flows out through the outflow groove, passing through the space in the buffer chamber, so that the explosion impact is gradually slowed down, avoiding the impact from acting instantly on the inner wall of the explosion-proof power supply box body 1, and correspondingly reducing the damage to the explosion-proof power supply box body 1 caused by the impact.

[0043] The buffer plate 3 is slidably connected to the inner wall of the explosion-proof power supply box body 1. When the buffer plate 3 is subjected to the impact force, the buffer plate 3 can be pushed to squeeze the elastic sheet 31 so that the elastic sheet 31 generates deformation energy. Through the cooperation of the buffer plate 3 and the elastic sheet 31, the direct impact on the inner wall of the explosion-proof power supply box body 1 is further reduced. The setting of the buffer plate 3 improves the explosion resistance and service life of the explosion-proof power supply box body 1, increases the safety of the explosion-proof power supply box body 1, and avoids the explosion of the explosion-proof power supply body 11 inside the explosion-proof power supply box body 1. The pressure generated by the explosion rushes out of the interior of the explosion-proof power supply box body 1, thereby correspondingly increasing the stability of the explosion-proof power supply box body 1.

[0044] When the buffer plate 3 moves toward the inner wall of the explosion-proof power supply box body 1, the buffer plate 3 can drive the fixed protective shell 42 and the mobile protective shell 45 to move accordingly, and then when the soft baffle plate 46 on the mobile protective shell 45 contacts the airbag 4, the mobile protective shell 45 can be resisted from continuing to move through the action of the soft baffle plate 46. At this time, when the buffer plate 3 continues to drive the fixed protective shell 42 to move, the fixed protective shell 42 can slide on the outer wall of the mobile protective shell 45, so that the puncture needle 47 passes through the inside of the soft baffle plate 46 to puncture the airbag 4, so that the nitrogen inside the airbag 4 can be released, and the nitrogen can be diluted The nitrogen can release oxygen concentration in the air to reduce it to the minimum level at which the flame cannot be maintained, thereby playing a fire extinguishing role. When the nitrogen is dispersed in the explosion-proof power supply box body 1, it can prevent the explosion-proof power supply body 11 from catching fire after the explosion. At the same time, the nitrogen will absorb heat during the release process, which will rapidly reduce the temperature in the fire source area, helping to extinguish the flame and prevent re-ignition, thereby avoiding the explosion-proof power supply body 11 from catching fire after the explosion. Accordingly, it prevents the explosion-proof power supply box body 1 from catching fire after the explosion, thereby reducing the loss caused by the explosion of the explosion-proof power supply body 11 and reducing the cost of maintenance and replacement.

[0045] By setting up the movable protective shell 45 and the soft baffle 46, the puncture needle 47 is protected inside the fixed protective shell 42, so that the puncture needle 47 is prevented from accidentally puncturing the airbag 4 when it is not needed to work, and the nitrogen inside the airbag 4 is released. Correspondingly, a physical barrier is provided for the puncture needle 47, so that it is isolated when it is not needed to work, thereby preventing the risk of the puncture needle 47 accidentally puncturing the airbag 4 and further increasing the stability of the puncture needle 47.

[0046] When the buffer plate 3 drives the fixed protective shell 42 to move, the push plate 21 moves accordingly, and then when the push plate 21 moves to one side of the explosion-proof tube 2, the push plate 21 contacts the T-shaped fixing rod 22, and then the push plate 21 continues to move forward, so that the push plate 21 can slide toward the explosion-proof tube 2 in the square inside of the explosion-proof tube 2, and then when the position where the T-shaped fixing rod 22 contacts one side of the push plate 21 enters the inside of the strip groove, the magnetic plate 1 27 and the magnetic plate 2 212 can enter the range of the magnetic field, and the sliding groove 28 limits the mounting plate 25, so that when the magnetic plate 1 27 and the magnetic plate 2 212 enter the range of the magnetic field, the magnetic plate 1 27 cannot approach the magnetic plate 2 212. At this time, the suction force between the two can be used to suck the magnetic plate 212 to fit the magnetic plate 1 27, and then the magnetic plate 2 212 moves toward the position of magnetic plate 27, which can drive the T-shaped fixing rod 22 to move out from the inside of the strip groove, thereby releasing the limit of the explosion-proof plate 211 by the T-shaped fixing rod 22, and then through the force of the third spring 210, the explosion-proof plate 211 can be pulled into the inner wall of the temporary storage groove 29, so that the explosion-proof pipe 2 is opened, thereby releasing the pressure inside the explosion-proof power supply box body 1, reducing the internal pressure level of the explosion-proof power supply box body 1, and avoiding the damage of the explosion to the surrounding environment and personnel. Correspondingly, with the release of the internal pressure of the explosion-proof power supply box body 1, the shock wave generated by the explosion will also be alleviated to a certain extent, which helps to reduce the damage of the explosion to the surrounding environment and personnel. At the same time, it prevents the explosion-proof power supply box body 1 from rupturing and deforming when the pressure inside the explosion-proof power supply box body 1 is too high, further reducing the risk of rupture of the explosion-proof power supply box body 1.

[0047] When the explosion-proof plate 211 is opened, the push plate 21 can push the T-shaped fixing rod 22 to continue to move toward the inner part of the explosion-proof pipe 2. When the T-shaped fixing rod 22 contacts the baffle plate 213 and continues to move, the baffle plate 213 can be pushed to rotate on the support rod 214, so that one side of the baffle plate 213 moves to the position of the U-shaped limiting rod 26. Through the arrangement of the U-shaped limiting rod 26 and the baffle plate 213, the T-shaped fixing rod 22 will not complete pushing the baffle plate 213 open. By tilting the baffle plate 213 on the explosion-proof pipe 2, the pressure discharged from the inside of the explosion-proof pipe 2 is blocked, thereby avoiding the pressure discharged through the explosion-proof pipe 2 from being directly ejected to cause safety hazards to the surrounding environment and personnel. Correspondingly, through the arrangement of the baffle plate 213, the pressure changes direction and is discharged to the ground through the bottom of the baffle plate 213, thereby preventing the pressure from directly ejecting to cause damage to the surrounding environment.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
