Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary energy-saving transformation of electric devices, and in particular to a power supply structure and method based on a standard air switch. Background Art

[0002] At present, a large amount of inventory has been accumulated in infrastructure such as air-conditioning rooms, lighting systems, and industrial plants. This part of the inventory will be the main market customer for energy-saving transformation. Due to the lack of original technology, the equipment is mainly used to achieve functions, and no refined management is carried out to save power consumption. Connecting all devices to edge computing in a digital way, through refined management, and with auxiliary sensors to achieve energy-saving control, the efficiency of the original system will be improved. This will be the main means of energy-saving transformation for the aftermarket.

[0003] For equipment that requires energy-saving renovation, it is generally necessary to collect the main information of the equipment through the controller. In particular, for projects such as industrial refrigeration and air conditioning that are turned on all year round, the equipment cannot be powered off during the energy-saving renovation process. There are generally no reserved power terminals inside the cabinet. Therefore, collecting power supply and voltage signals of equipment such as controllers and electric meters has become a major problem.

[0004] The existing construction plan is mainly live wiring. The original equipment has too much power, so the terminal is generally larger in diameter, while the signal acquisition equipment has a smaller power and is generally equipped with a smaller wire diameter. For the installation of the electric meter, since the real-time voltage of the three-phase electricity needs to be obtained, the wire diameter of the voltage signal is also smaller. It is very difficult to crimp a small wire diameter and a large wire diameter to a large terminal at the same time, especially in the case of live operation, which will greatly increase the risk of equipment and personnel. Summary of the invention

[0005] The purpose of the present invention is to provide a power supply structure and method based on a standard air switch. By setting a sliding structure equipped with a contact probe, the sliding structure drives the contact probe to obtain power through the screw contact of the contact air switch. During the power supply process, there is no contact between personnel and the strong wire, which solves the problems existing in the prior art. In order to achieve the above purpose, the present invention solves it through the following technical solutions:

[0006] In a first aspect, the present invention provides a power supply structure based on a standard air switch, comprising:

[0007] The column has a connecting structure at the bottom, which can be inserted into the installation gap at the bottom of the air switch;

[0008] A sliding structure has one end that slides with the column, and a contact probe that is cantilevered at the other end. The contact probe is connected to a lead wire, and the movement of the sliding structure drives the contact probe to contact or disengage with the screw contact of the air switch. When in contact, the contact probe cooperates with the connecting structure up and down to clamp the air switch together.

[0009] As a further technical solution, the sliding structure is provided with a locking structure to limit its sliding on the column.

[0010] As a further technical solution, the column and the locking structure both have one-way teeth that cooperate with each other, and in the cooperative state, the contact probe only has a movement in a direction close to the screw contact point.

[0011] As a further technical solution, the locking structure includes a knob end, a lock tooth end and a spring arranged therebetween, the lock tooth end has the one-way teeth, and the knob end is used to apply or release the cooperation between the two one-way teeth.

[0012] As a further technical solution, the sliding structure has a mounting plate, the knob end is mounted on the mounting plate, arc-shaped protrusions are symmetrically arranged on the outer circumference of the knob end, and the mounting plate has a special-shaped through hole that is only adapted to allow the arc-shaped protrusions to pass through.

[0013] As a further technical solution, a limiting protrusion is provided on the arc-shaped protrusion, and the mounting plate is provided with a limiting groove cooperating with the limiting protrusion to limit the self-rotation of the knob end.

[0014] As a further technical solution, the connecting structure is a leg, which is provided at the bottom end of the column and arranged in a T shape therewith.

[0015] As a further technical solution, the left and right side surfaces of the sliding structure are mating surfaces.

[0016] As a further technical solution, the contact probe is a spring-type probe.

[0017] In a second aspect, the present invention provides a working method of the power supply structure based on the standard air switch according to the first aspect, comprising the following steps:

[0018] Configure the same number of power-taking structures based on standard air switches according to the level of the air switch. When in use, insert the connecting structure at the bottom of the column into the installation gap at the bottom of the air switch, press down the sliding structure to drive the contact probe to press the screw contact of the air switch, and at the same time, the contact probe and the connecting structure cooperate up and down to clamp the air switch together, and the power-taking process is realized.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) The present invention is provided with a column and a sliding structure, wherein the column serves as a supporting component for the movement of the sliding structure, and the contact probe is cantilevered and installed on the sliding structure; during the power-drawing process, the connection structure at the bottom of the column is inserted into the installation gap at the bottom of the air switch, and the sliding structure is pressed down to drive the contact probe to contact the screw contact of the air switch, and power is drawn at this time. The power-drawing structure does not need to disassemble the original air switch connection line, and power is drawn by contacting the screw contact of the air switch. During the power-drawing process, personnel have no contact with the strong wires, which not only ensures the power-drawing efficiency, but also ensures the safety of personnel.

[0021] (2) After the contact probe contacts the screw contact, the present invention cooperates with the connecting structure arranged at the bottom of the column, one is located at the top of the air switch and the other is located at the bottom, clamping the power supply structure on the air switch from the upper and lower ends to prevent the power supply structure from slipping, thereby ensuring the stability and reliability of the power supply process.

[0022] (3) Due to the setting of the one-way teeth of the column and the locking structure of the present invention, the sliding structure drives the contact probe to move downward only along the column. In the process of preparing to draw power, the sliding structure is pressed down so that the contact probe always has a tendency to gradually contact the screw contact until it contacts the screw contact. At this time, the power-drawing structure also clamps the air switch to ensure that the contact between the contact probe and the screw contact is stable, thereby avoiding the problem of intermittent power drawing caused by the contact probe being out of contact or unstable contact due to external force factors after contacting the screw contact.

[0023] (4) The present invention provides a spring-type probe. On the one hand, the elasticity of the probe can compensate for the problem of misaligned teeth in the one-way tooth matching process; on the other hand, the elasticity of the probe can press the probe against the screw contact to ensure stable contact between the contact probe and the screw contact.

DETAILED DESCRIPTION

[0034] The technical solutions in typical embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] Embodiment 1

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a power supply structure based on a standard air switch, including a column 22 , a sliding structure 23 , and a contact probe 26 disposed on the sliding structure 23 .

[0037] The bottom end of the column 22 is provided with a connection structure, which can extend into the installation gap at the bottom of the air switch 11. The air switch 11 is installed on the guide rail 13, and the guide rail 13 is installed on the back plate 12. After the air switch 11 is installed on the guide rail 13, there is an installation gap between the bottom of the air switch 11 and the back plate 12.

[0038] In this embodiment, the connection structure is a leg 25, which is arranged at the bottom of the column 22 and in a T-shaped arrangement. The leg 25 can be inserted into the installation gap at the bottom of the air switch 11. When the sliding structure 23 slides downward along the column 22, the leg 25 at the bottom of the column can clamp the air switch 11.

[0039] One end of the sliding structure 23 is slidably matched with the column 22, and the other end is cantilevered to set a contact probe 26, which is connected to the lead-out line 21. The movement of the sliding structure 23 drives the contact probe 26 to contact or disengage with the screw contact 111 of the air switch 11. The screw contact 111 is a screw at the terminal of the air switch 11 for tightening the original air switch connecting line 14. The screw contact 111 is usually exposed at the top of the hole, and the screw is used to tighten the original air switch connecting line 14, so the screw contact 111 is charged.

[0040] In this embodiment, a through hole is provided at the cantilevered end of the sliding structure 23, and a contact probe 26 is fixedly installed in the through hole. The end of the contact probe 26 is connected to the power-taking structure lead wire 21. When the sliding structure 23 is pressed down, the contact probe 26 presses the screw contact 111 of the air switch 11 to lead out the power.

[0041] In this embodiment, a column 22 and a sliding structure 23 are provided, wherein the column 22 serves as a supporting component for the movement of the sliding structure 23, and the contact probe 26 is cantilevered and installed on the sliding structure 23; during the power-drawing process, the bottom connecting structure of the column 22 is inserted into the installation gap at the bottom of the air switch 11, and the sliding structure 23 is pressed down to drive the contact probe 26 to contact the screw contact 111 of the air switch 11, and power is drawn at this time. The power-drawing structure does not need to disassemble the original air switch 11 connection line, and the power is drawn by contacting the screw contact 111 of the air switch 11. During the power-drawing process, personnel have no contact with the strong wires, which not only ensures the power-drawing efficiency, but also ensures the safety of personnel. At the same time, it provides a fast power-drawing method for energy-saving transformation of a huge amount of existing infrastructure.

[0042] After the contact probe 26 contacts the screw contact 111, it cooperates with the connection structure arranged at the bottom of the column 22 to clamp the air switch 11. One of them is located at the top of the air switch and the other is located at the bottom, and the power-taking structure is clamped on the air switch 11 from the upper and lower ends to prevent the power-taking structure from slipping and ensure the stability and reliability of the power-taking process.

[0043] During on-site installation, the number of power supply structures can be flexibly configured according to the number of circuit breakers (P number) to adapt to three-phase and single-phase electricity. Figure 1 and Figure 2 In FIG. 2 , two power extraction structures are shown.

[0044] In order to better utilize the installation space, the left and right side surfaces of the sliding structure 23 of the adjacent power taking structures are mating surfaces, that is, the adjacent surfaces of the sliding structures 23 of the two adjacent power taking structures are mating surfaces.

[0045] In this embodiment, in order to ensure that the sliding structure does not move at a certain position on the column, the sliding structure 23 is provided with a locking structure to limit its sliding on the column 22 .

[0046] like Figure 4 and Figure 5 As shown, both the column 22 and the locking structure have mutually matched one-way teeth, and in the mutually matched state, the contact probe 26 can only move in the direction close to the screw contact 111, that is, it has one-way movement.

[0047] In this embodiment, one side of the column 22 has a one-way tooth, and the direction of the tooth is downward, and the locking structure also has a one-way tooth, and the one-way tooth of the locking structure is opposite to the one-way tooth of the column 22, that is, the one-way tooth of the locking structure is upward. The one-way tooth of the locking structure and the one-way tooth of the column 22 cooperate with each other. In the state of mutual cooperation, the contact probe 26 can only move in the direction close to the screw contact 111.

[0048] In this embodiment, due to the setting of the column 22 and the one-way teeth of the locking structure, the sliding structure 23 drives the contact probe 26 to move downward only along the column 22. In the process of preparing to draw power, the sliding structure 23 is pressed down so that the contact probe 26 always has a tendency to gradually contact the screw contact 111 until it contacts the screw contact 111. At this time, the power-drawing structure also clamps the air switch 11, ensuring that the contact between the contact probe 26 and the screw contact 111 is stable, thereby avoiding the problem of intermittent power drawing caused by the contact probe 26 being out of contact or unstable contact due to external force factors after contacting the screw contact 111.

[0049] like Figure 5 As shown, the locking structure includes a knob end 241, a lock tooth end 242 and a spring 243 disposed therebetween. The lock tooth end 242 has a one-way tooth, and the knob end 241 is used to apply or release the cooperation between the two one-way teeth. The lock tooth end 242 is a slider structure, and a slide groove is provided inside the sliding structure to cooperate with it.

[0050] The spring 243 presses the one-way teeth of the locking tooth end 242 against the one-way teeth of the column 22, so that the two one-way teeth are matched. When the spring 243 is pressed, the sliding structure 23 is pressed, the locking tooth end 242 retreats and disengages and immediately re-matches with the one-way teeth below the column 22, and the sliding structure 23 can only move downward along the column 22, and is stuck upward.

[0051] After the knob end 241 is rotated, the lock tooth end can be pulled out by the spring. At this time, the one-way teeth of the lock tooth end and the column fail, and the locking structure can be disassembled.

[0052] Specifically, Figure 6 , Figure 7 and Figure 8As shown, the sliding structure 23 has a mounting plate 231, and the knob end 241 is mounted on the mounting plate 231. The outer circumference of the knob end 241 is symmetrically provided with arc-shaped protrusions 2411, and the mounting plate 231 has a special-shaped through hole 2311 that is only adapted to the passage of the arc-shaped protrusions 2411. The difference between the special-shaped through hole 2311 and the ordinary through hole is that the inside of the through hole is also symmetrically provided with arc-shaped protrusions, and the rest of the through hole is just for the arc-shaped protrusions 2411 on the outer circumference of the knob end 241 to pass through. After passing through, the knob end 241 is rotated, and the arc-shaped protrusions of the special-shaped through hole 2311 cooperate with the arc-shaped protrusions 2411 of the knob end 241 to prevent the knob end 241 from being pulled out.

[0053] A limiting protrusion 2412 is provided on the arc-shaped protrusion 2411, and a limiting groove 2312 cooperating with the limiting protrusion 2412 is provided on the mounting plate 231 to limit the self-rotation of the knob end 241, and pressing and rotating can release the limit or apply the limit.

[0054] In this embodiment, the contact probe 26 is a spring-type probe. When the corresponding one-way teeth are matched, the contact probe 26 does not necessarily contact the screw contact 111 exactly. Two situations may occur: one is that when the contact probe 26 contacts the screw contact 111, the one-way teeth may match and misaligned teeth may occur; the other is that when the one-way teeth are matched, the contact probe 26 may be suspended in the air without contact, and then the misaligned teeth may occur when pressed down. By setting a spring-type probe, on the one hand, the elasticity of the probe can compensate for the misaligned teeth problem during the one-way tooth matching process; on the other hand, the elasticity of the probe can press the probe against the screw contact 111 to ensure stable contact between the contact probe 26 and the screw contact 111.

[0055] Embodiment 2

[0056] This embodiment provides a working method according to the power supply structure based on the standard air switch as described in the first embodiment, including the following steps:

[0057] The same number of power-taking structures based on the standard air switch 11 are configured according to the level of the air switch 11. When in use, the connecting structure at the bottom of the column 22 is inserted into the installation gap at the bottom of the air switch 11, and the sliding structure 23 is pressed down to drive the contact probe 26 to press the screw contact 111 of the air switch 11. At the same time, the contact probe 26 and the connecting structure cooperate with each other to clamp the air switch 11, and the power-taking process is realized.

[0058] Although the present invention has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention.
