Description

Technical Field

[0001] This invention relates to the field of electrical equipment cleaning technology, and in particular to a remote-controlled insulated spray gun specifically designed for 10 kV high-voltage live water rinsing. Background Technology

[0002] Kashgar Prefecture is located at the intersection of the Taklamakan Desert, the Kunlun Mountains, and the Tianshan Mountains, resulting in relatively severe pollution levels. Of its 12 counties (cities), only Tashkurgan County is classified as Class A pollution, with a relatively lighter pollution level. The other 11 counties are classified as Class D or E pollution, indicating severe pollution. Every year, severe pollution causes significant power outages due to flashover. To effectively prevent large-scale power outages caused by flashover, it is possible to conduct live-line water flushing on some important power grid equipment without interrupting power. However, most areas can only conduct live-line flushing on 0.4 kV low-voltage equipment, and large-scale live-line flushing on 10 kV equipment is almost nonexistent. Furthermore, the existing safety tools for live-line water flushing are all self-made by suppliers of the cleaning fluid, failing to meet safety regulations and posing serious safety hazards and risks of electric shock during use.

[0003] Therefore, it is necessary to provide a solution to the above-mentioned technical problems by providing a remote-controlled insulated spray gun for identifying 10 kV high-voltage live water flushing through testing. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by disclosing a remote-controlled insulating spray gun for 10 kV high-voltage live water rinsing, which solves the problem that existing live rinsing tools cannot meet the cleaning requirements of voltage levels of 10 kV and below.

[0005] The technical solution adopted by this invention to solve its technical problem is: a 10 kV high-voltage live water flushing special remote-controlled insulating spray gun, including an insulating rod and a remote control transmitter. The insulating rod is provided with an insulating tube. The front end of the insulating tube is connected to the nozzle through a solenoid valve. The rear end of the insulating tube extends out of the insulating rod and is fixed to a quick connector. An insulating skirt is fixed to the front end of the insulating rod. A mobile power supply and a remote control receiver are provided between the insulating skirt and the solenoid valve. The rear end of the insulating rod is provided with a first insulating sleeve and a second insulating sleeve. The second insulating sleeve is located between the first insulating sleeve and the quick connector. The mobile power supply powers the solenoid valve.

[0006] Preferably, the insulating rod has a bracket near the first insulating sheath, and the remote control transmitter is mounted on the bracket.

[0007] Preferably, the bracket has a slot with its opening facing the insulating umbrella skirt, and the remote control transmitter is inserted into the slot.

[0008] Preferably, the bracket includes two clamping plates and a support plate, with the two clamping plates respectively disposed on both sides of the remote control transmitter, and the bottom of the remote control transmitter fitting against the support plate.

[0009] Preferably, the bracket is fixed above the first insulating sheath by a clamp.

[0010] Preferably, the insulating rod comprises a plurality of hollow tubes, and two adjacent hollow tubes are fixed by an insulating joint.

[0011] Preferably, the nozzle is a rotary nozzle.

[0012] Preferably, it also includes a protective case, in which the power bank and remote control receiver are housed.

[0013] Preferably, the protective shell is fixed to the insulating rod by a clamp.

[0014] Preferably, the first insulating sheath and the second insulating sheath are provided with different marking layers.

[0015] Compared with existing technologies, this invention provides comprehensive protection for operator safety during the rinsing process. Specifically, it employs triple safety protection: an insulating tube, an insulating rod, and a first insulating sleeve. Secondly, personnel can remotely control the solenoid valve to rinse the insulators from a safe distance. Thirdly, if incorrect operation causes cleaning fluid to flow onto the insulating rod, the insulating skirt prevents the cleaning fluid from continuing to flow downwards, eliminating potential hazards during rinsing. Fourthly, the second insulating sleeve ensures that a sufficient safe distance is maintained between the operator holding the first insulating sleeve and the quick-connect fitting, preventing water leakage at the quick-connect fitting and related safety hazards.

[0021] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0022] The following is in conjunction with the appendix Figure 1 and attached Figure 3 Further describing the invention, a 10 kV high-voltage live-line water flushing remote-controlled insulated spray gun includes an insulating rod 1 and a remote control transmitter 2. The insulating rod 1 contains an insulating tube 010. The front end of the insulating tube 010 is connected to a nozzle 4 via a solenoid valve 3. The rear end of the insulating tube 010 extends out of the insulating rod 1 and is fixed to a quick-connect connector 5. The quick-connect connector 5 is connected to a liquid supply pipe, which is connected to a booster pump. An insulating skirt 6 is fixed to the front end of the insulating rod 1. A power supply and a remote control receiver are located between the insulating skirt 6 and the solenoid valve 3. The rear end of the insulating rod 1 has a first insulating sleeve 7 and a second insulating sleeve 8. Manual live-line flushing can be performed manually by holding the first insulating sleeve 7 on the ground or inside an insulated bucket truck, enabling flexible application in multiple scenarios. The second insulating sleeve 8 is located between the first insulating sleeve 7 and the quick-connect connector 5. The power supply powers the solenoid valve 3. The remote control transmitter 2 and the remote control receiver constitute the remote control. This invention provides comprehensive protection for operator safety during the rinsing process, achieving complete electrical isolation between the operator and energized electrical equipment, and between the operator and the energized water rinsing solution. Specifically: an insulating tube 010 is installed in the insulating rod 1, and then a first insulating sleeve 7 is installed on the insulating rod 1, providing triple safety protection between the operator and the cleaning solution. Secondly, personnel can rinse the insulators by remotely opening the solenoid valve 3 from a safe distance, which helps protect the operator's safety. Thirdly, if an error occurs and cleaning solution flows onto the insulating rod 1, the insulating skirt 6 prevents the cleaning solution from continuing to flow downwards, eliminating potential hazards during the rinsing process. Fourthly, the second insulating sleeve 8 ensures that when the operator holds the first insulating sleeve 7, a sufficient safe distance is maintained from the quick-connect joint 5, preventing water leakage at the quick-connect joint 5 and potential safety hazards.

[0023] In another embodiment of the present invention: the insulating rod 1 is provided with a bracket 9 near the first insulating sleeve 7, and the remote control transmitter 2 is mounted on the bracket 9. When the operator holds the first insulating sleeve 7, it is convenient to press the button on the remote control transmitter 2 to remotely control the opening and closing of the solenoid valve 3.

[0024] In another embodiment of the present invention, the bracket 9 has a slot facing the insulating skirt 6, and the remote control transmitter 2 is inserted into the slot. With this arrangement, during rinsing, one person can hold the first insulating sleeve 7 to hold the insulating rod 1, while another person holds the remote control transmitter 2 to remotely control the opening and closing of the solenoid valve 3.

[0025] One implementation of the support 9: Refer to the attached document. Figure 2 The bracket 9 includes two card plates 91 and a support plate 92. The two card plates 91 are respectively located on both sides of the remote control transmitter 2. The bottom of the remote control transmitter 2 is attached to the support plate 92. The button on the remote control transmitter 2 is located between the two card plates 91.

[0026] One embodiment of mounting bracket 9 on insulating rod 1: bracket 9 is fixed above first insulating sleeve 7 by clamp 011. This arrangement allows bracket 9 to be quickly mounted on insulating rod 1, with clamp 011 fitting against the upper end of first insulating sleeve 7.

[0027] In another embodiment of the present invention, the insulating rod 1 comprises a plurality of hollow tubes 11, and two adjacent hollow tubes 11 are fixed by an insulating joint 12. Specifically, the insulating rod 1 is four meters long and is divided into two two-meter-long hollow tubes 11 for easy manufacturing and carrying.

[0028] In another embodiment of the present invention, the nozzle 4 is a rotating nozzle, which facilitates expanding the cleaning area. The present invention can install different nozzles 4 according to different scenarios. For example, when the insulator is heavily soiled, a regular nozzle is installed for high-pressure cleaning. When the insulator has a large amount of dust, a rotating nozzle can be installed.

[0029] As another embodiment of the present invention: This embodiment also includes a protective shell 012, in which the power supply and remote control receiver are disposed. The protective shell 012 is made of metal and can effectively shield electromagnetic fields, effectively protecting the power supply and remote control inside when flushing the insulators of 10 kV electrical equipment. The solenoid valve 3 is also a solenoid valve with a metal shell.

[0030] One embodiment of the protective shell 012 being mounted on the insulating rod 1: The protective shell 012 is fixed to the insulating rod 1 by a clamp 011.

[0031] As another embodiment of the present invention: the first insulating sleeve 7 and the second insulating sleeve 8 are respectively provided with different marking layers to distinguish them and prevent operators from holding the wrong insulating sleeve.

[0032] The specialized live-line working tool provided by this invention is mainly used for live-line cleaning of electrical equipment with voltage levels of 10 kV and below. Its key technical parameters are designed strictly in accordance with industry regulations, and it can be widely used in the operation and maintenance of power grids with voltage levels of 10 kV and below. It has the following advantages:
