Description

Technical Field

[0001] This utility model relates to the field of installation and fixing technology, and in particular to an installation mechanism and a leakage current detection bearing device. Background Technology

[0002] When operating and maintaining outdoor electrical equipment, it is necessary to detect leakage current in the electrical equipment. There are many types of leakage current detection devices, including leakage current detectors. A leakage current detector is an instrument used to detect leakage current phenomena. It can detect the operating current of current-type electric shock protectors and detect unbalanced leakage current that is less than the operating current of the current-type electric shock protector.

[0003] Current leakage current detectors are typically used by manually holding the probe directly to the area to be tested. This traditional method places the user close to the area, increasing the risk of accidental contact. After use, the detector is often left on a table, leading to dust accumulation on the probe and reduced sensitivity. Furthermore, malfunctions can cause the device to lose accuracy or fail to detect the area properly, potentially resulting in misjudgments by operators. Utility Model Content

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0038] Example 1

[0039] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides an installation mechanism, including a connecting component 100, which includes a first sleeve 101, a threaded rod 102 disposed at one end of the first sleeve 101, and a limiting platform 101a disposed on the outer wall of the first sleeve 101.

[0040] The adsorption assembly 200 includes a second sleeve 201 and a suction cup 202 disposed at one end of the second sleeve 201.

[0041] The first sleeve 101 has a threaded rod 102 at one end, which is composed of a cylinder and threads on its outer wall. At the other end of the first sleeve 101 away from the threaded rod 102, there is a limiting platform 101a with a radius larger than that of the first sleeve 101. The advantage of this design is that items that need to be connected can be strung together, then pressed against the surface of the limiting platform 101a, and finally clamped using a nut. If the width of the items to be connected is less than the length of the threaded rod 102, a nut can be screwed into the end of the threaded rod 102 near the first sleeve 101 first, and then another nut can be used to clamp the items to be connected.

[0042] The first sleeve 101 and the second sleeve 201 are detachably connected. For example, the second sleeve 201 has a cylindrical structure with an inner diameter larger than the outer diameter of the first sleeve 101, allowing for a sliding connection and detachable connection. The suction cup 202 is made of a deformable material and operates on the principle of air pressure. The suction cup 202 is pressed against the surface of the object to be adsorbed, reducing the internal space. Then, pulling the suction cup 202 outwards expands the internal space, reducing the internal air pressure and creating an adsorption effect. Finally, the first sleeve 101 and the second sleeve 201 are slidably connected to install the object.

[0043] Preferably, the second sleeve 201 is slidably provided with a support rod 203 that allows the first sleeve 101 to slide.

[0044] To further stabilize the suction cup, the support rod 203 is slidably connected to the second sleeve 201. When installation is required, the suction cup 202 is pressed onto the flat surface, and then one end of the second sleeve 201 contacts the flat surface to be installed. The suction cup 202 is pressed down, and the support rod 203 is pulled outward, which increases the internal space and then decreases the internal air pressure, creating a pressure difference with the outside, thereby adsorbing the suction cup 202 onto the flat surface.

[0045] Furthermore, the outer wall of the support rod 203 is slidably provided with a movable block 204 that can be limited.

[0046] To prevent the support rod 203 from being sucked back, a moving block 204 is provided on the outer wall of the support rod 203 to restrict its movement. For example, the outer wall of the limiting rod 203 is threaded, and the inner wall of the moving block 204 is threaded accordingly. When the support rod 203 is pulled out, the moving block 204 is rotated to abut against the surface of the second sleeve 201, thereby restricting the movement of the support rod 203.

[0047] Preferably, the radius of the first sleeve 101 is larger than the outer diameter of the threaded rod 102.

[0048] The radius of the first sleeve 101 is larger than the radius of the threaded rod 102. The advantage of this design is that it allows for different processing for different application scenarios based on the size of the hole of the object to be connected.

[0049] Preferably, the surface of the movable block 204 that conforms to the outer wall of the support rod 203 is provided with a limiting block 204a;

[0050] The outer wall of the support rod 203 is provided with a first groove 203a for the sliding of the limiting block 204a. There are two first grooves 203a, and the two first grooves 203a are staggered and connected.

[0051] A first surface 203a-1 is formed between two misaligned first sliding grooves 203a on the outer surface of the support rod 203. To prevent the support rod 203 from being sucked back, the suction cup 202 is pressed onto the flat surface. Then, one end of the second sleeve 201 contacts the flat surface to be installed, presses down the suction cup 202, and pulls the support rod 203 outward. Then, the support rod 203 is rotated, and the limiting block 204a abuts against the first surface 203a-1, preventing the support rod 203 from sliding back.

[0052] In summary, the existing leak detection device is first installed using the connecting component 100. Then, the suction cup 202 is pressed onto the flat surface. Next, one end of the second sleeve 201 contacts the surface to be installed, and the suction cup 202 is pressed down. The support rod 203 is then pulled outward, and the support rod 203 is rotated. The limiting block 204a abuts against the first surface 203a-1, preventing the support rod 203 from sliding back. Finally, the first sleeve 101 is inserted into the surface of the support rod 203, thus completing the installation of the leak detection device. This eliminates the need for close-range operation by personnel, improving operational safety.

[0053] Example 2

[0054] Reference Figures 1-6 This is the second embodiment of the present utility model, which includes a connecting component 100, including a first sleeve 101, a threaded rod 102 disposed at one end of the first sleeve 101, and a limiting platform 101a disposed on the outer wall of the first sleeve 101.

[0055] The adsorption assembly 200 includes a second sleeve 201 and a suction cup 202 disposed at one end of the second sleeve 201.

[0056] The first sleeve 101 has a threaded rod 102 at one end, which is composed of a cylinder and threads on its outer wall. At the other end of the first sleeve 101 away from the threaded rod 102, there is a limiting platform 101a with a radius larger than that of the first sleeve 101. The advantage of this design is that items that need to be connected can be strung together, then pressed against the surface of the limiting platform 101a, and finally clamped using a nut. If the width of the items to be connected is less than the length of the threaded rod 102, a nut can be screwed into the end of the threaded rod 102 near the first sleeve 101 first, and then another nut can be used to clamp the items to be connected.

[0057] The first sleeve 101 and the second sleeve 201 are detachably connected. For example, the second sleeve 201 has a cylindrical structure with an inner diameter larger than the outer diameter of the first sleeve 101, allowing for a sliding connection and detachable connection. The suction cup 202 is made of a deformable material and operates on the principle of air pressure. The suction cup 202 is pressed against the surface of the object to be adsorbed, reducing the internal space. Then, pulling the suction cup 202 outwards expands the internal space, reducing the internal air pressure and creating an adsorption effect. Finally, the first sleeve 101 and the second sleeve 201 are slidably connected to install the object.

[0058] Preferably, the second sleeve 201 is slidably provided with a support rod 203 that allows the first sleeve 101 to slide.

[0059] To further stabilize the suction cup, the support rod 203 is slidably connected to the second sleeve 201. When installation is required, the suction cup 202 is pressed onto the flat surface, and then one end of the second sleeve 201 contacts the flat surface to be installed. The suction cup 202 is pressed down, and the support rod 203 is pulled outward, which increases the internal space and then decreases the internal air pressure, creating a pressure difference with the outside, thereby adsorbing the suction cup 202 onto the flat surface.

[0060] Furthermore, the outer wall of the support rod 203 is slidably provided with a movable block 204 that can be limited.

[0061] To prevent the support rod 203 from being sucked back, a moving block 204 is provided on the outer wall of the support rod 203 to restrict its movement. For example, the outer wall of the limiting rod 203 is threaded, and the inner wall of the moving block 204 is threaded accordingly. When the support rod 203 is pulled out, the moving block 204 is rotated to abut against the surface of the second sleeve 201, thereby restricting the movement of the support rod 203.

[0062] Preferably, the radius of the first sleeve 101 is larger than the outer diameter of the threaded rod 102.

[0063] The radius of the first sleeve 101 is larger than that of the threaded rod 102. The advantage of this design is that it can be used to handle different application scenarios according to the size of the hole of the object to be connected.

[0064] Preferably, the surface of the first sleeve 101 away from the threaded rod 102 has an indentation for the mounting cylinder 101b, and the inner wall of the mounting cylinder 101b is provided with threads;

[0065] The outer wall of the support rod 203 is provided with threads that are compatible with the mounting cylinder 101b.

[0066] The first sleeve 101 has an indented mounting cylinder 101b at the end away from the threaded rod 102, and the inner wall of the mounting cylinder 101b is provided with threads. At the same time, the outer surface of the support rod 203 is provided with threads, so that the support rod 203 and the first sleeve 101 can be screwed together, increasing the installation stability.

[0067] Preferably, the surface of the movable block 204 that conforms to the outer wall of the support rod 203 is provided with a limiting block 204a;

[0068] The outer wall of the support rod 203 is provided with a first groove 203a for the limiting block 204a to slide.

[0069] In this design, the support rod 203 is slidably connected to the movable block 204, and the limiting block 204a slides along the inside of the first groove 203a, restricting the movable block 204 from rotating along the surface of the support rod 203. The advantage of this design is that when the movable block 204 is directly rotated to drive the support rod 203 to rotate, at the same time, the screw is connected to the inside of the mounting cylinder 101b of the first sleeve 101, and the support rod 203 is moved outward along the inside of the second sleeve 201, expanding the space inside the suction cup 202.

[0070] The second sleeve 201 and the support rod 203 are sealed together.

[0071] In order to ensure the sealing of the suction cup 202, a sealing treatment is performed at the sliding point between the second sleeve 201 and the support rod 203, such as applying lubricating oil or inserting a rubber gasket between them.

[0072] In summary, by first using the connecting component 100 to install the existing leak detection device, the suction cup 202 can be pressed onto the surface to be adsorbed. Then, the support rod 203 can be pulled out slightly to create a certain suction force. Next, the mounting cylinder 101b in the first sleeve 101 can be aligned with the support rod 203. Then, the rotating block 204 can be rotated to drive the support rod 203 to rotate, so that the support rod 203 is screwed into the mounting cylinder 101b. This process not only connects the connecting component 100 and the adsorption component 200, but also allows the support rod 203 to slide outward along the inside of the second sleeve 201, increasing the internal space of the suction cup 202 and gradually increasing the suction force until the two sides of the moving block 204 are respectively attached to the first sleeve 101 and the second sleeve 201, thus realizing the installation of the leak detection device. This eliminates the need for close-range operation by personnel, improving work safety.

[0073] Example 3

[0074] Reference Figures 1-8 This is the third embodiment of the present invention, which further provides a leakage current detection bearing device. It includes a first clamping shell 301 and a second clamping shell 302;

[0075] The first clamping housing 301 is provided with a first threaded hole that can be screwed onto the threaded rod 102;

[0076] The second clamping shell 302 is provided with a through hole.

[0077] The leakage current detection device mainly consists of: an LCD screen, an audible and visual alarm, a self-locking switch, a Luneburg lens, and a grounding wire interface.

[0078] The self-locking switch is the master switch for the entire device. Pressing the switch turns the device on, and the power indicator on the self-locking switch illuminates. Pressing the switch turns the device off, and the power indicator on the self-locking switch turns off. The grounding wire must be securely connected to the grounding wire interface. When the self-locking switch is pressed, the device starts and checks for leakage in the casing. If leakage is detected, the audible and visual alarm will sound, and the LCD screen will display the device's operating status and leakage information. After a certain period of inactivity, the LCD screen will turn off, and the device will enter standby mode. When a living organism is detected through the Luneburg lens, the device automatically enters the operable operating state.

[0079] The leakage current detection device also includes: a probe, an electrical signal line, a leakage current sensor, a battery, and a power interface. The power interface can be connected to a solar panel, which charges the battery through the interface; alternatively, it can be connected to an external power source to charge the battery. The probe passes through the device's insulating casing and contacts the cabinet shell. If the cabinet shell leaks current, the leakage signal is transmitted through the probe to the electrical signal line, which passes through the hole in the leakage current sensor. The leakage current sensor receives the signal from the electrical signal line and displays the leakage information on the LCD screen. If a leakage current is detected, an audible and visual alarm will sound simultaneously. The battery serves as the energy supply and reserve component for the entire device, providing power. The leakage current detection device is installed on the equipment casing. The solar panel can be attached to any position on the casing depending on the angle of sunlight. One end of the grounding wire is connected to the leakage current detection device, and the other end is connected to the ground.

[0080] These devices are all located between the first clamping shell 301 and the second clamping shell 302. The first clamping shell 301 is provided with a first threaded hole that is adapted to the threaded rod 201. The second clamping shell 302 is provided with a through hole of the same diameter as the first sleeve 101. The first sleeve 101 can be directly passed through the through hole of the second clamping shell 302 and then screwed into the first threaded hole. Since the radius of the first sleeve 101 is larger than the radius of the first threaded hole, the first sleeve 101 will abut against the bottom of the through hole, so that the first clamping shell 301 and the second clamping shell 302 are connected.

[0081] The outer wall of the first clamping shell 301 is provided with a Luneburg lens M.

[0082] The first clamping shell 301 faces outwards from the mounting surface, and the Luneburg lens M needs to be installed on the outer surface of the first clamping shell 301 for easy inspection by operators.

[0083] In summary, multiple installation mechanisms can be reasonably designed according to the weight of the leakage current detection carrier device, that is, multiple through holes and first threaded holes can be reasonably distributed. Then, the first clamping shell 301 and the second clamping shell 302 are connected by the connecting component 100. Then, the suction cup 202 is pressed on the surface to be adsorbed. Then, the support rod 203 is pulled out slightly to form a certain suction force. Holding the leakage current detection carrier device, the mounting cylinder 101b in the first sleeve 101 is aligned with the support rod 203. Then, the moving block 204 is rotated to drive the support rod 203 to rotate, so that the support rod 203 is screwed into the mounting cylinder 101b. This process not only connects the connecting component 100 and the adsorption component 200, but also allows the support rod 203 to slide outward along the inside of the second sleeve 201, increasing the internal space of the suction cup 202 and gradually increasing the suction force until the two sides of the moving block 204 are respectively attached to the first sleeve 101 and the second sleeve 201, thus completing the installation.

[0084] The advantage of this design is that it does not require a specific installation structure; all that is needed is a flat surface on the equipment to be tested, and most equipment has a smooth outer shell. At the same time, the position of the mounting mechanism can be adjusted according to the equipment, and disassembly is also very convenient. Furthermore, it does not require drilling holes in the mounting equipment or installing other special equipment, thus improving practicality.
