[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0023] This utility model discloses a novel triangular high-strength discharge rod, which mainly includes a discharge rod tip 1, a grounding wire bolt 2, an insulating rod 3, and an insulating partition 4. The insulating rod 3 is a hollow regular triangular prism structure. The interior of the insulating rod 3 is divided into three independent chambers along its axial direction by the insulating partition 4. A high-voltage electrode, a grounding electrode, and control circuits are installed in the chambers. A detachable hollow discharge rod tip 1 is installed at the top of the insulating rod 3. The discharge rod tip 1 is a truncated cone structure with a smaller top and a larger bottom. A grounding wire bolt 2 is threadedly connected to the side wall near the bottom.

[0024] Before discharge, connect the discharge tip 1 to the insulating rod 3, and connect the grounding wire to the grounding bolt 2. The grounding wire is a multi-strand copper core flexible wire, and ensure that the grounding clamp at the end of the grounding wire is firmly connected to the earth to form a safe current loop. During use, the operator holds the insulating rod 3 and aligns the discharge tip 1 with the object to be discharged. Because the discharge tip 1 is designed as a truncated cone, it has more contact points with the object being discharged, facilitating stable contact. During the discharge process, the control circuit controls the discharge process between the high-voltage electrode and the grounding electrode, and promptly conducts the charge during the discharge process to the earth through the grounding wire, ensuring the safety of equipment and personnel. The insulating rod adopts a triangular design, making it easier for the operator to grip and less prone to slipping. During prolonged operation or delicate discharge operations, it allows for better control of the position and angle of the discharge rod, ensuring the accuracy and safety of the discharge.

[0025] The insulating rod 3 includes a first connecting rod 301, a second connecting rod 302, a first nut 303, a positioning tube 304, a first connector 305, and a first limiting pin 306. The bottom end of the first connecting rod 301 is fitted with a second connecting rod 302 for easy disassembly. A hollow first connector 305 is also installed at the bottom end of the first connecting rod 301. The first limiting pin 306 is radially arranged inside the first connector 305. The top end of the second connecting rod 302 is fitted with a positioning tube 304 that mates with the first connector 305. The positioning tube 304 has an axially oriented first groove 3041 that engages with the first limiting pin 306. A rotatable first nut 303 is fitted onto the positioning tube 304. The outer wall of the first connector 305 has an external thread that connects to the first nut 303. The first connecting rod 301 and the second connecting rod 302 are connected by the first connector 305 and the positioning tube 304. The two parts of the insulating rod 3 are connected and secured with the first cap 303 to ensure a tight connection and prevent loosening or separation during use. The length can be adjusted according to the actual application scenario. The cooperation between the first limiting pin 306 and the first slot 3041 serves to align and position the parts. When the first connector 305 is inserted into the positioning tube 304, the first limiting pin 306 will embed into the first slot 3041, restricting the relative rotation of the two parts and ensuring that the edges of the triangular prism are aligned. The edges can serve as reference points, which helps to improve the operability of the discharge rod. At the same time, it is convenient to disassemble and assemble, which is beneficial for storage, transportation and maintenance, saves space and facilitates the replacement of parts.

[0026] The first connecting rod 301 has a hollow second connecting head 307 at its top end. A second limiting pin 308 is radially arranged inside the second connecting head 307. A connecting tube 101 is located at the bottom of the discharge rod tip 1. A rotatable second nut 102 is fitted onto the connecting tube 101. A second slot 1011 is formed on the connecting tube 101 to engage with the second limiting pin 308. An external thread is formed on the outer wall of the second connecting head 307 to threadedly connect with the second nut 102. Through the cooperation of the second connecting head 307, the second limiting pin 308, the connecting tube 101, and the second nut 102, the first connecting rod 301 is connected and fixed to the discharge rod tip 1, ensuring that the discharge rod tip 1 can be firmly installed on the insulating rod 3 and will not loosen or fall off during use. The second limiting pin 308 and the second slot 1011... The snap-fit ​​mechanism serves to align and position the components, limiting the relative rotation of the connecting tube 101 and the second connector 307, ensuring the normal operation of the discharge rod, improving the discharge effect and safety, and facilitating the replacement and maintenance of the discharge rod tip 1.

[0027] The insulating partition 4 is made of high-insulation-strength, high-temperature-resistant ceramic material or high-performance insulating plastic; ensuring reliable insulation performance between electrodes and withstanding high voltage, thereby improving the performance and reliability of the discharge rod.

[0028] The outer shell of the insulating rod 3 is made of carbon fiber reinforced composite material, which enables the shell to withstand high external pressure without significant deformation or damage, while also having good weather resistance and corrosion resistance, making it suitable for complex and ever-changing usage environments.

[0029] The three side edges of the insulating rod 3 are rounded, which can reduce the damage caused by sharp edges to the human body or equipment by scratches and collisions, and improve safety during use.

[0030] The insulating rod 3 is entirely covered with a high-performance silicone rubber insulating sleeve; this effectively prevents the risk of electric shock to operators and also provides buffer protection for the internal structure.

[0031] Work process:

[0032] Before discharge, connect the discharge tip 1 to the insulating rod 3, and connect the grounding wire to the grounding bolt 2. The grounding wire is a multi-strand copper core flexible wire, and ensure that the grounding clamp at the end of the grounding wire is firmly connected to the earth to form a safe current loop. During use, the operator holds the insulating rod 3 and aligns the discharge tip 1 with the object to be discharged. Because the discharge tip 1 is designed as a truncated cone, it has more contact points with the object being discharged, facilitating stable contact. During the discharge process, the control circuit controls the discharge process between the high-voltage electrode and the grounding electrode, and promptly conducts the charge during the discharge process to the earth through the grounding wire, ensuring the safety of equipment and personnel. The insulating rod adopts a triangular design, making it easier for the operator to grip and less prone to slipping. During prolonged operation or delicate discharge operations, it allows for better control of the position and angle of the discharge rod, ensuring the accuracy and safety of the discharge.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
