Abstract
Description
Technical Field
[0001] This application relates to the field of insulator testing equipment technology, and in particular to a water spray bottle for testing the hydrophobicity of insulators. Background Technology
[0002] An insulator is a special type of insulating control that is installed between conductors at different potentials or between a conductor and a grounding component. It can withstand voltage and mechanical stress and insulate bare conductors from the ground. Alternatively, it can be used to insulate current-carrying conductors at different potentials in electrical installations and appliances from each other. It has sufficient insulation strength, mechanical strength, heat resistance, and moisture resistance.
[0003] Insulators can be classified in several ways, including: according to installation method (suspension insulators and post insulators); according to constituent materials (porcelain insulators, glass insulators, and composite insulators); and according to operating voltage level (low-voltage insulators and high-voltage insulators).
[0004] Before insulators are put into use, their various properties need to be tested. One of these tests is the hydrophobicity of the insulator, which refers to the insulator's surface's ability to repel and resist water. This property is crucial for the reliability of power systems.
[0005] Spraying water onto insulators using a kettle is a common method for testing the hydrophobicity of insulators. Generally speaking, the optimal test distance is 25cm between the kettle spout and the insulator. However, currently, when spraying water onto insulators using a kettle, operators estimate the 25cm test distance visually or use a stick of equal length to roughly control it. This affects the accuracy of the hydrophobicity test to some extent, and directly affects the determination of the hydrophobicity level of the insulator. Utility Model Content
[0006] To facilitate operators in controlling the distance between the water bottle and the insulator, this application provides a water spray bottle for testing the hydrophobicity of insulators.
[0007] This application provides a water spray bottle for testing the hydrophobicity of insulators, which adopts the following technical solution:
[0008] A water spray bottle for testing the hydrophobicity of insulators includes a bottle body, a distance measuring device, and an alarm device. The distance measuring device and the alarm device are both disposed on the bottle body and are electrically connected. The distance measuring device is used to measure the distance between the nozzle of the bottle body and the insulator to be tested. The alarm device can issue different warning messages based on the distance measuring result of the distance measuring device.
[0009] With the above technical solution, before the operator needs to conduct a hydrophobicity test on the insulator using this equipment, the distance measuring device is activated to measure the distance between the nozzle of the kettle body and the insulator to be tested, and the alarm device is activated to issue an alarm message based on the distance measuring result.
[0010] Operators set different alarm mechanisms for the alarm device. For example, the optimal test distance is 25cm (here, to simplify the explanation of the principle, the allowable fluctuation range of the optimal test distance is ignored). The specific settings are as follows: when the distance between the nozzle of the kettle body and the insulator to be tested is equal to 25cm, an alarm signal is issued (the alarm signal includes flashing lights, whistling, vibration, etc.); when the distance between the nozzle of the kettle body and the insulator to be tested is greater than or less than 25cm, another alarm signal is issued.
[0011] The two warning signals mentioned above are significantly different, making it easy for operators to distinguish between them. This allows them to determine the distance between the nozzle of the kettle body and the insulator to be tested based on the warning signal, thus enabling operators to perform hydrophobicity testing on the insulator at the optimal distance and improve the accuracy of the hydrophobicity test.
[0012] In a preferred embodiment, the present invention can be further configured such that: the ranging device includes an infrared rangefinder, the infrared rangefinder is mounted on the kettle body, and the infrared rangefinder and the nozzle of the kettle body are on the same side.
[0013] The above technical solution uses an infrared rangefinder to measure the distance between the nozzle of the kettle body and the insulator to be tested, so as to directly obtain the distance measurement result and provide the distance measurement information to the alarm device, so that the alarm device can release different warning signals.
[0014] In a preferred embodiment, the present invention can be further configured such that the infrared emission axis of the infrared rangefinder and the water spray axis of the kettle body are arranged parallel to each other.
[0015] By employing the above technical solution, the accuracy of distance measurement by the infrared rangefinder is improved because the infrared emission axis of the infrared rangefinder and the water spray axis of the kettle body are parallel to each other.
[0016] In a preferred embodiment, the present invention can be further configured such that: the alarm device includes an alarm, the alarm is mounted on the kettle body, and the alarm and the infrared rangefinder are respectively disposed on both sides of the kettle body.
[0017] Through the above technical solution, the alarm emits different warning signals so that operators can determine whether the current distance is the optimal distance based on the warning signals, and thus perform the water spraying operation.
[0018] In a preferred embodiment, the present invention can be further configured as follows: a first half-ring and a second half-ring are provided on the kettle body, a connector is provided between the first half-ring and the second half-ring, the first half-ring and the second half-ring are connected by the connector and installed on the kettle body, the infrared rangefinder is installed on the first half-ring, and the alarm is installed on the second half-ring.
[0019] With the above technical solution, the infrared rangefinder and the alarm are installed on half-ring one and half-ring two respectively, and half-ring one and half-ring two are installed on the kettle body through connectors. Therefore, the infrared rangefinder and the alarm can be detachably installed on the kettle body. When the kettle is damaged, the operator can install the infrared rangefinder and the alarm that can still be used on another kettle, so that they can further play their related functions.
[0020] In a preferred embodiment, the present invention can be further configured such that: a protective sheet one is installed on the inner wall of the first semi-ring, and a protective sheet two is installed on the inner wall of the second semi-ring.
[0021] Through the above technical solution, the first and second protective plates can be made of materials with a certain degree of toughness, which reduces the possibility of damage to the kettle body caused by the pressure of the first and second semi-rings on the kettle body.
[0022] In a preferred embodiment, the present invention can be further configured such that: the connecting member includes a bolt and a nut, the bolt and the nut are threadedly connected, and the first half-ring and the second half-ring are connected by the bolt and the nut.
[0023] Through the above technical solution, half-ring one and half-ring two are connected by bolts and nuts, thereby enabling the infrared rangefinder and alarm to be installed on the kettle body, realizing the detachable installation of the infrared rangefinder and alarm on the kettle body.
[0024] In a preferred embodiment, the present invention can be further configured such that: both the first half-ring and the second half-ring are provided with an extension portion, and each extension portion is provided with a plurality of through holes for the bolts to pass through.
[0025] With the above technical solution, when the operator needs to install an infrared rangefinder and alarm on a larger kettle, the bolt is inserted into the through hole on the outer side, so as to leave a larger space between half ring one and half ring two, so that half ring one and half ring two can be installed on the larger kettle, and thus the infrared rangefinder and alarm can be installed on the larger kettle.
[0026] In summary, this utility model has the following beneficial technical effects:
[0027] 1. By setting an infrared rangefinder and an alarm on the kettle, the distance between the nozzle of the kettle body and the insulator to be tested is measured and an alarm signal is issued, respectively. This allows the operator to determine the distance between the nozzle of the kettle body and the insulator to be tested, thereby enabling the operator to conduct the hydrophobicity test on the insulator at the optimal distance and improve the accuracy of the hydrophobicity test.
[0028] 2. Both the infrared rangefinder and the alarm are detachably installed on the kettle body via connectors, so that the infrared rangefinder and the alarm can perform distance detection and issue warning signals on different kettle bodies, thus expanding the applicability of this device;
[0029] 3. By inserting bolts into different through holes, operators can install infrared rangefinders and alarms on kettles of different sizes, further expanding the applicability of this equipment. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.
[0036] This application discloses a water spray bottle for testing the hydrophobicity of insulators.
[0037] See attached document Figure 1 As shown, a water spray bottle for testing the hydrophobicity of insulators includes a bottle body 1. The water storage bottle portion of the bottle body 1 is cylindrical and vertically arranged, and the bottom surface of the bottle body 1 is horizontal.
[0038] See attached document Figure 1As shown, a nozzle is provided on one side of the kettle body 1, from which water stored inside the kettle body 1 is sprayed out. A handle 13 is installed on the other side of the kettle body 1. The grip portion of the handle 13 is angled to facilitate the operator holding the kettle to perform the water spraying operation. A push-button switch is integrated on the handle 13, allowing the operator to issue a water spraying command while holding the kettle.
[0039] See attached document Figure 1 and attached Figure 2 As shown, the kettle body 1 is equipped with a distance measuring device 2 and an alarm device 3.
[0040] See attached document Figure 1 and attached Figure 2 As shown, the ranging device 2 includes an infrared rangefinder 21, which is mounted on the kettle body 1. The infrared rangefinder 21 is used to measure the distance between the nozzle of the kettle body 1 and the insulator to be tested. The infrared rangefinder 21 and the nozzle of the kettle body 1 are on the same side, and the infrared emission axis of the infrared rangefinder 21 and the water spray axis of the nozzle of the kettle body 1 are parallel to each other, which improves the accuracy of the distance measurement by the infrared rangefinder 21.
[0041] See attached document Figure 1 and attached Figure 2 As shown, the alarm device 3 includes an alarm 31, which is electrically connected to an infrared rangefinder 21. The alarm 31 can emit different warning signals based on the ranging results from the infrared rangefinder 21, such as easily distinguishable signals like different colored lights, flashing lights, whistles, and vibrations. The alarm 31 is mounted on the kettle body 1, and the alarm 31 and the infrared rangefinder 21 are respectively located on opposite sides of the kettle body 1; that is, the nozzle and the infrared rangefinder 21 are on the same side, and the handle 13 and the alarm 31 are on the same side.
[0042] See attached document Figure 1 As shown, the nozzle is positioned above the infrared rangefinder 21, which helps protect the infrared rangefinder 21. Alternatively, to reduce the refraction interference of water flow on infrared light, the nozzle can also be positioned below the infrared rangefinder 21. The alarm 31 is positioned below the handle 13, which helps protect the alarm 31. Alternatively, to reduce the interference of the alarm 31 on the operator's hands, the alarm 31 can also be positioned above the handle 13.
[0043] Before the operator needs to perform a hydrophobicity test on the insulator using this equipment, first hold the handle 13 and pick up the water-filled kettle body 1; then, activate the infrared rangefinder 21 and the alarm 31 to establish an electrical connection between them; next, move the kettle close to the insulator to be tested and constantly observe the alarm signal of the alarm 31; finally, after the alarm 31 issues a warning signal indicating the optimal distance, the operator stops moving the kettle and sprays water onto the insulator by pressing the switch to perform the hydrophobicity test.
[0044] Based on the ranging feedback from the infrared rangefinder 21, the alarm 31 emits different warning signals. After the operator observes the warning signal at the optimal distance, the water spraying operation is performed to control the distance between the water tank and the insulator, thereby improving the accuracy of the insulator's hydrophobicity detection.
[0045] See attached document Figure 1 and attached Figure 2 As shown, the kettle body 1 is provided with a semi-ring 11 and a semi-ring 22, which provide mounting positions for the infrared rangefinder 21 and the alarm 31. The semi-ring 11 and the semi-ring 22 are the same size, face opposite directions, are both semi-circular, and have a rectangular cross-section. The semi-ring 11 and the semi-ring 22 can be joined together to form a complete ring, which is snapped onto the outside of the kettle body 1.
[0046] See attached document Figure 1 and attached Figure 2 As shown, the infrared rangefinder 21 is installed on half-ring 11, and the alarm 31 is installed on half-ring 22. The infrared rangefinder 21 and the alarm 31 can be detachably installed on the kettle body 1. When the kettle body 1 is damaged, the operator can install the infrared rangefinder 21 and the alarm 31 that can still be used on another kettle, so that they can further play their related roles.
[0047] See attached document Figure 1 and attached Figure 2 As shown, several sets of connectors 4 are provided between semi-ring one 11 and semi-ring two 12, and these sets of connectors 4 are evenly distributed on both sides of the kettle body 1. Since the structure of each set of connectors 4 is basically the same, only one set of connectors 4 will be described in detail below. Each set of connectors 4 includes a bolt 41 and a nut 42. Semi-ring one 11 and semi-ring two 12 are connected and installed on the kettle body 1 by bolts 41 and nuts 42, and bolts 41 and nuts 42 are threaded together.
[0048] See attached document Figure 2 and attached Figure 3As shown, both ends of the first half-ring 11 and the second half-ring 12 are provided with extensions 5. The extensions 5 are cuboid in shape, and their length direction is consistent with the radial direction of the half-ring 11 or the second half-ring 12. The extensions 5 and the half-ring 11 or the second half-ring 12 are integrally formed. Each extension 5 has several through holes 51 for bolts 41 to pass through, and the through holes 51 are evenly distributed along the length direction of the extension 5.
[0049] When the operator needs to install the infrared rangefinder 21 and the alarm 31 on the kettle body 1, the first half ring 11 and the second half ring 12 are fitted together on the outside of the kettle body 1. Then, the bolt 41 is inserted into the through hole 51 of the extension 5, and the nut 42 is threaded onto the bolt 41. Under the pressure of the nut 42 and the head of the bolt 41, the first half ring 11 and the second half ring 12 are fixed to the kettle body 1, thereby completing the installation of the infrared rangefinder 21 and the alarm 31.
[0050] In addition, by inserting bolts 41 into different through holes 51, the operator can increase the distance between half-ring 11 and half-ring 12, thereby enabling the infrared rangefinder 21 and alarm 31 to be installed on kettle bodies 1 of different sizes, thus expanding the applicability of the infrared rangefinder 21 and alarm 31.
[0051] See attached document Figure 2 and attached Figure 3 As shown, a protective sheet 111 is attached to the arc-shaped inner wall of semi-ring 11 near semi-ring 2 12, and a protective sheet 2 121 is attached to the arc-shaped inner wall of semi-ring 2 12 near semi-ring 11. Both protective sheets 111 and 2 121 are made of flexible material, which strengthens the protection of the kettle body 1.
[0052] The implementation principle of this embodiment is as follows: the alarm 31 emits different warning signals based on the ranging feedback from the infrared rangefinder 21. After the operator observes the warning signal of the optimal distance, the water spraying operation is performed to control the distance between the water tank and the insulator, thereby improving the accuracy of the insulator's hydrophobicity detection.
[0053] The embodiments described in this specific implementation are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be covered within the scope of protection of this utility model.
