Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioner grounding, and particularly relates to a safe air conditioner grounding protection device. Background Technique

[0002] Air conditioner grounding is an important link to ensure electrical safety, and its main functions include but are not limited to the following points: Prevent electric shock: Air conditioner grounding can conduct the leakage current into the ground to avoid the risk of electric shock to users. Energy conservation and emission reduction: Good grounding helps the air conditioner operate more efficiently and reduce energy consumption. Avoid equipment damage: Grounding can help stabilize the working voltage of the air conditioner and prevent equipment damage caused by voltage fluctuations. Lightning protection: Air conditioner grounding can absorb the current generated by lightning to a certain extent and reduce the damage to the air conditioner. Prolong service life: Appropriate grounding can reduce the working temperature of the air conditioner and prolong its service life. Installation steps of air conditioner grounding: Prepare tools and materials: The tools to be prepared include wire cutters, wire strippers, insulating tape and ground wires. Determine the position of the ground wire: Generally, the air conditioner ground wire should be installed on the base of the air conditioner outdoor unit to ensure that the ground wire can be firmly fixed on the base. Prepare the ground wire: Use wire cutters and wire strippers to strip one end of the ground wire to expose the copper wire, and wrap it with insulating tape to ensure that the ground wire will not short-circuit with other wires. Install the ground wire: Use a screwdriver to loosen the screw on the base, then pass the non-stripped end of the ground wire through the hole on the base, and connect it to the ground wire terminal on the air conditioner outdoor unit. Finally, tighten the screw again to fix the ground wire. Test the ground wire: Use a multimeter to test whether the ground wire is working properly. The resistance value of the ground wire should be 0, indicating that the ground wire is working properly.

[0003] At present, when installing the existing grounding wire of the air conditioner outdoor unit, generally, the ground wire and the air conditioner outdoor unit are connected by bolts, and then the ground wire is connected to the building's grounding network. However, since the air conditioner outdoor unit is installed in the external environment, rainwater, birds and other objects will fall on the ground wire, resulting in the ground wire being pulled. And because the existing grounding device cannot buffer the pulling force on the ground wire, the grounding wire installed on the air conditioner outdoor unit by bolts is in poor contact with the air conditioner outdoor unit or falls off, affecting the connection stability of the grounding wire of the air conditioner outdoor unit, and thus affecting the safety of the air conditioner outdoor unit. Based on this, a safe air conditioner grounding protection device is proposed. Content of the Utility Model

A connecting grounding mechanism is clamped inside the clamping bin 4. The connecting grounding mechanism is connected to the external unit grounding mechanism and is connected to the building's grounding grid.

[0021] When in use, when the grounding wire needs to be connected to the outdoor unit 1 of the air conditioner, insert it into the fixed sleeve 2 through the groove 3 of the connecting grounding mechanism, and make the outdoor unit grounding mechanism and the connecting grounding mechanism abut tightly. Then rotate the connecting grounding mechanism so that the connecting grounding mechanism is clamped in the clamping bin 4, and the connection between the outdoor unit 1 of the air conditioner and the grounding wire is completed. Finally, connect the grounding wire to the building's grounding network;

[0022] Both installation and disassembly are relatively convenient, facilitating personnel use.

[0023] Such as Figure 2 、 Figure 3 and Figure 4 As shown, the outdoor unit grounding mechanism includes a pressing spring 501 arranged in the fixed sleeve 2. The bottom of the pressing spring 501 is fixedly connected with a pressing sleeve 502. The pressing sleeve 502 and the pressing spring 501 are made of insulating materials. The inner top of the pressing sleeve 502 is fixedly connected with an upper conductive disc 503. The top of the upper conductive disc 503 is fixedly connected with an outdoor unit grounding wire 504. The outdoor unit grounding wire 504 is fixedly connected to the bottom of the outdoor unit 1 of the air conditioner. The outdoor unit grounding wire 504 passes through the pressing sleeve 502 and is fixedly connected with the pressing sleeve 502. The outdoor unit grounding wire 504 is arranged inside the pressing spring 501. The pressing spring 501 is fixedly connected to the bottom of the outdoor unit 1 of the air conditioner. A through hole is opened at the bottom of the fixed sleeve 2. The inner diameter of the pressing sleeve 502 is larger than the inner diameter of the through hole. The connecting grounding mechanism includes a clamping rod 602 clamped in the clamping bin 4. The end of the clamping rod 602 is fixedly connected with a connecting pipe 601. The top of the connecting pipe 601 is fixedly connected with an installation sleeve 603. The inner bottom of the installation sleeve 603 is fixedly connected with a lower conductive disc 604. The outer wall of the connecting pipe 601 is fixedly connected with a fixing ring 605. The bottom of the fixing ring 605 is fixedly connected with a connecting spring 606. The bottom of the connecting spring 606 is fixedly connected with a connecting plate 607. The connecting pipe 601, the installation sleeve 603, the connecting spring 606 and the connecting plate 607 are made of insulating materials. The middle of the connecting plate 607 is fixedly connected through with a connecting grounding wire 608. One end of the connecting grounding wire 608 is fixedly connected with the lower conductive disc 604, and the other end is fixedly connected with the grounding network. The installation sleeve 603 is adapted to the pressing sleeve 502. The outer diameter of the installation sleeve 603 is smaller than the inner diameter of the through hole. The clamping rod 602 is adapted to the groove 3. The bottom of the upper conductive disc 503 and the top of the lower conductive disc 604 are in contact with each other. The part of the connecting grounding wire 608 located inside the connecting pipe 601 is arranged in a spiral shape.

[0024] When in use, when connecting the grounding wire to the outdoor unit 1 of the air conditioner, first hold the connecting pipe 601 by hand and insert the installation sleeve 603 into the fixed sleeve 2 through the through hole, and align the clamping rod 602 with the groove 3. Then, the connecting pipe 601 can be pushed upward so that the installation sleeve 603 is inserted into the tightening sleeve 502, and further the upper conductive disk 503 and the lower conductive disk 604 are fitted together until the clamping rod 602 enters the fixed sleeve 2. During this process, the tightening spring 501 will be in a compressed state. Then, the connecting pipe 601 can be rotated to drive the clamping rod 602 to rotate. When the clamping rod 602 rotates to the position where the clamping chamber 4 is located, the clamping rod 602 will enter the clamping chamber 4 under the action of the tightening spring 501 in the compressed state, and the connection of the grounding wire to the outdoor unit 1 of the air conditioner is completed. Then, the connecting grounding wire 608 can be connected to the grounding grid of the building, so that the leakage current generated by the outdoor unit 1 of the air conditioner is conducted into the upper conductive disk 503 through the outdoor unit grounding wire 504, then conducted into the connecting grounding wire 608 through the lower conductive disk 604, and finally conducted to the ground by the grounding grid;

[0025] When the connecting grounding wire 608 is pulled by rain, birds or other objects, at this time, the connecting grounding wire 608 will pull the connecting plate 607 to move downward, and further the connecting spring 606 will be stretched, so that the connecting grounding wire 608 in a spiral shape in the connecting pipe 601 is elongated, thus realizing the buffering of the pulling force received by the connecting grounding wire 608, preventing the grounding wire from being in poor contact with or falling off the outdoor unit 1 of the air conditioner, ensuring the stability of the connection, and thus ensuring the safety of the outdoor unit 1 of the air conditioner;

[0026] When disassembly is required, only need to push the connecting pipe 601 upward so that the clamping rod 602 is disengaged from the clamping chamber 4, and rotate the connecting pipe 601 so that the clamping rod 602 reaches the position where the groove 3 is located, and the disassembly operation is completed. The disassembly and assembly are simple and fast, without the need to use tools, which is convenient for personnel to use.

[0027] The above-described embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
