Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical testing technology, and specifically to a multifunctional low-voltage electrical testing device for intelligent low-voltage engineering. Background Technology

[0002] Low-voltage systems refer to electrical systems within buildings or facilities that use lower voltage and current. Compared to high-voltage systems, low-voltage systems generally operate at voltages not exceeding 36 volts (V) and are primarily used for information transmission, control signal transmission, and energy management. Low-voltage systems encompass a variety of functions and technical fields and are an important component of modern building intelligence.

[0003] The implementation of low-voltage systems involves multiple stages, requiring the involvement of a professional team from project planning, scheme design, equipment selection to installation, commissioning, acceptance, and delivery. Meanwhile, regular maintenance is equally crucial to ensure the system's normal operation. This includes inspecting and repairing hardware, updating and optimizing software systems, and providing personnel training.

[0004] However, with the increasing functionality and complexity of low-voltage systems, traditional single-function testing equipment can no longer meet practical needs. For example, during the installation, commissioning, and maintenance of low-voltage systems, technicians often need to carry multiple types of testing instruments to complete different testing tasks. Furthermore, there are often many low-voltage lines to be tested, and some testing instruments have limited connectors, requiring multiple instruments. This not only increases the complexity and cost of the work but may also lead to misjudgments due to equipment incompatibility or improper operation.

[0005] Therefore, the present invention provides a multifunctional low-voltage detection device for intelligent low-voltage engineering to solve the above problems. Summary of the Invention

[0006] In view of the above situation and to overcome the shortcomings of the existing technology, the present invention provides a multifunctional low-voltage testing device for intelligent low-voltage engineering. It effectively solves the problem that existing low-voltage testing equipment requires testing a large number and variety of low-voltage lines, and that staff need to carry multiple instruments for testing, which increases the complexity and cost of the work.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A multifunctional low-voltage detection device for intelligent low-voltage engineering includes an installation mechanism. The installation mechanism includes a housing with at least two openings on one side. Each opening has an interface fixedly connected to it. A detector is disposed in the housing. Each interface is electrically connected to the detector via a conductive element. The conductive element includes two conductive posts electrically connected to the interface, arranged from top to bottom. The conductive element also includes two grounding posts electrically connected to the detector, arranged from bottom to top. A sliding post that moves up and down is disposed between the grounding posts and the conductive posts, and the sliding post contacts the grounding posts and the conductive posts.

[0009] Specifically, in the initial state, the sliding post contacts the upper electrical terminal and the upper conductive post, establishing a connection between the upper conductive post and the upper electrical terminal. During use, the low-voltage cable connector is inserted into the interface. A portion of the circuit in the low-voltage cable connector is connected to the detector via the upper conductive post and the upper electrical terminal. The detector then detects a portion of the circuit in the low-voltage cable. After detection, the sliding post is slid downwards, making contact with the lower electrical terminal and the lower conductive post, establishing a connection between the lower electrical terminal and the lower conductive post. The detector then detects another portion of the circuit in the low-voltage line via the lower conductive post and the lower electrical terminal.

[0010] By setting up the interface, the detection device can be connected to the low-voltage circuit. By setting up the power connection post and the conductive post, the low-voltage circuit can be connected to the detector, enabling the detector to detect the low-voltage circuit. Furthermore, by setting up the conductive post and the power connection post at the top and bottom, different parts of the circuit in the low-voltage circuit can be detected separately by sliding the post. This improves the versatility of the detection device, reduces the number of devices that personnel need to carry when testing low-voltage circuits, and reduces the complexity and cost of operation for personnel.

[0011] Furthermore, the interface includes two sets of contacts, which can be connected to two sets of contacts in the low-voltage line connector, and the two sets of lines in the low-voltage line connector are connected to the two sets of contacts in the low-voltage line connector.

[0012] Furthermore, the detector is existing technology and will not be described in detail.

[0013] Preferably, the sliding column is connected to a driving mechanism, which includes manual components of the same number as the openings. Each manual component is connected to a corresponding sliding column. Each manual component includes a sliding hole on the upper side of the housing. A push rod is slidably connected in the sliding hole. The bottom of the push rod is fixedly connected to the sliding column. A first spring is connected between the sliding column and the top wall of the housing. The first spring is sleeved on the push rod. A fixing rod is fixedly connected to the lower side of the sliding column. An iron block is fixedly connected to the bottom end of the fixing rod. A first magnetic block is provided on the lower side of the iron block. The first magnetic block is fixedly connected to the bottom wall of the housing through a connecting rod. A second magnetic block is provided on the lower side of the first magnetic block. The second magnetic block is fixedly connected to the bottom wall of the housing.

[0014] Specifically, in use, when the first spring is in its natural state, the sliding post is in contact with the upper conductive post and the upper contact post. When it is necessary to make the sliding post contact with the lower contact post and the conductive post, press the push rod down. The push rod moves downward, causing the sliding post to move downward, while simultaneously stretching the first spring. At the same time, the sliding post moves the iron block downward through the connecting rod. When the first magnetic block contacts the side of the iron block, stop pushing the push rod downward. At this point, the iron block's position is maintained by the attraction of the first magnetic block, thus connecting the lower conductive post and the lower contact post. When it is necessary to disconnect the weak current circuit, continue pressing the push rod down, causing the push rod to move the iron block downward. When the bottom surface of the iron block contacts the second magnetic block, stop pushing the push rod downward. The iron block remains stationary under the action of the second magnetic block, thus disconnecting the weak current circuit from the detector.

[0015] The manual mechanism allows users to move the sliding column up and down by pressing the push rod, thus switching the upper and lower electrical terminals on and off. The iron block, the first magnetic block, and the second magnetic block ensure that the position of the sliding column is maintained when switching the upper and lower electrical terminals on and off, facilitating the testing process.

[0016] Preferably, the driving mechanism further includes an automatic component, which includes a fixed plate fixedly connected to the bottom wall of the housing, a motor fixedly connected to the fixed plate, a lead screw fixedly connected to the output end of the motor, a threaded block threaded onto the lead screw, a sliding rod fixedly connected to the fixed plate, the threaded block slidably mounted on the sliding rod, an abutment frame fixedly connected to the bottom surface of the threaded block, the abutment frame being in the shape of an inverted trapezoid, an abutment rod fixedly connected to the iron block, and the abutment rod contacting the inclined surface of the abutment frame.

[0017] Specifically, in use, when the user is at the other end of the low-voltage line and needs to test it, the motor is started remotely. The motor's output drives the lead screw to rotate. The rotation of the lead screw, in conjunction with the limiting action of the sliding rod, causes the threaded block to move along the lead screw. As the threaded block moves, it drives the abutment frame to move. The inclined surface of the abutment frame contacts the abutment rod, causing the abutment rod to move downwards. The abutment rod then drives the iron block downwards. When the iron block contacts the first magnetic block, the motor stops rotating. When the user needs to disconnect the low-voltage line during testing, the motor is started again, causing the abutment frame to continue moving. The abutment frame continues to drive the abutment rod downwards. When the iron block contacts the second magnetic block, the bottom surface of the abutment frame just contacts the abutment rod.

[0018] By setting up automatic components, when it is inconvenient for the user to move to the location of the detection device, the motor can be started remotely, causing the motor to drive the lead screw to rotate. This, in turn, drives the abutment frame to move through the threaded block. The abutment frame then drives the iron block to move through the abutment rod, thereby realizing the movement of the sliding column and facilitating the detection of low-voltage circuits.

[0019] Furthermore, the first magnetic block and the second magnetic block are electromagnets.

[0020] Specifically, when the iron block needs to be reset, the power supply to the first and second magnetic blocks is disconnected by remote control, so that the magnetism of the first and second magnetic blocks disappears, and the iron block is reset under the action of the first spring.

[0021] By setting up the electromagnets of the first and second magnetic blocks, the resetting of the iron block can be remotely controlled, thus facilitating the detection of weak current circuits.

[0022] Furthermore, electromagnets are existing technology and will not be described in detail.

[0023] Preferably, a protective mechanism is provided on the side of the housing, and the protective mechanism is located at the opening. The protective mechanism includes two symmetrically opened grooves on the side of the housing, a slider is slidably connected in each groove, the two sliders extend out of the grooves respectively, and a protective plate is fixedly connected to each slider. The protective plate can close the opening.

[0024] Specifically, when using the testing device, slide the protective plate upwards. The protective plate will cause the slider to slide upwards in the groove, exposing the opening so that the low-voltage line connector can be connected to the interface. After the testing device is used, slide the protective plate downwards, causing the protective plate to cause the slider to slide downwards, and the protective plate will close the interface.

[0025] The protective mechanism allows the interface to be exposed by sliding the protective plate, facilitating the connection of low-voltage circuits. Furthermore, the protective plate can be used to seal the interface after the testing device is used, slowing down the oxidation process of the interface during storage and reducing the entry of dust.

[0026] Furthermore, fixed magnetic blocks are fixedly connected to the upper and lower sidewalls of the slide, and the fixed magnetic blocks are magnetically attracted to the slider.

[0027] Specifically, during use, when the protective plate moves upward, it causes the slider to move upward, so that the slider is magnetically attracted to the fixed magnetic block on the upper side, thus maintaining the position of the protective plate; when the protective plate moves downward, it causes the slider to move downward, so that the slider is magnetically attracted to the fixed magnetic block on the lower side, thus maintaining the position of the protective plate.

[0028] The use of fixed magnetic blocks ensures that the protective plate remains in its position when opened and closed, facilitating the opening and closing of the interface.

[0029] Preferably, the housing is provided with a C-shaped handle, and the handle is fixedly connected to the housing.

[0030] Furthermore, the detector is electrically connected to a controller, which is disposed on the top surface of the housing and is fixedly connected to the housing.

[0031] Preferably, a circular plate is fixedly connected to the top end of the push rod.

[0032] Preferably, C-shaped elastic contact pieces are fixedly connected to both ends of the sliding column.

[0033] By using elastic contact pieces, the sliding post can make better contact with the conductive post and the grounding post during the sliding repositioning process.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] 1. Through the interface settings, the detection device can be connected to the low-voltage circuit. Through the setting of the power connection post and the conductive post, the low-voltage circuit can be connected to the detector, enabling the detector to detect the low-voltage circuit. Furthermore, through the setting of the upper and lower conductive posts and the power connection post, different parts of the circuit in the low-voltage circuit can be detected separately by sliding the column. This improves the versatility of the detection device, reduces the number of devices that personnel need to carry when testing low-voltage circuits, and reduces the complexity and cost of operation for personnel.

[0036] 2. The manual component allows the user to move the sliding column up and down by pressing the push rod, thereby switching the upper and lower electrical terminals on and off. The iron block, the first magnetic block, and the second magnetic block ensure that the position of the sliding column is maintained when switching the upper and lower electrical terminals on and off, facilitating the testing process.

[0037] 3. By setting up automatic components, when it is inconvenient for the user to move to the location of the detection device, the motor can be started remotely, causing the motor to drive the lead screw to rotate, which in turn drives the abutment frame to move through the threaded block. The abutment frame then drives the iron block to move through the abutment rod, thereby realizing the movement of the sliding column, which facilitates the detection of low-voltage circuits.

[0038] 4. By setting up the electromagnets of the first and second magnetic blocks, the iron block can be remotely controlled to reset, thus facilitating the detection of weak current circuits.

[0039] 5. The protective mechanism allows the interface to be exposed by sliding the protective plate, facilitating the connection of low-voltage circuits. Furthermore, the protective plate can seal the interface after the testing device is used, slowing down the oxidation process of the interface during storage and reducing dust ingress.

[0040] 6. The fixed magnetic block ensures the protective plate remains in position during opening and closing, facilitating the opening and closing of the interface. The elastic contact piece ensures better contact between the sliding post and the conductive and contacting posts during sliding and repositioning. Attached Figure Description

[0056] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0057] A multi-functional low-voltage detection device for intelligent low-voltage engineering, such as Figure 1 , 2As shown in Figures 3 and 4, the device includes an installation mechanism 1. The installation mechanism 1 includes a housing 11. Three openings 12 are provided on one side of the housing 11. An interface 13 is fixedly connected to each opening 12. A detector 14 is provided in the housing 11. Each interface 13 is electrically connected to the detector 14 through a conductive element 15. The conductive element 15 includes two conductive posts 151 electrically connected to the interface 13, arranged from top to bottom. The conductive element 15 also includes two grounding posts 152 electrically connected to the detector 14, arranged from bottom to top. A sliding post 153 that moves up and down is provided between the grounding post 152 and the conductive post 151. The sliding post 153 contacts the grounding post 152 and the conductive post 151.

[0058] Specifically, in the initial state, the sliding post 153 contacts the upper terminal post 152 and the upper conductive post 151, thus connecting the upper conductive post 151 and the upper terminal post 152. In use, the low-voltage cable connector is inserted into the interface 13. Part of the circuit in the low-voltage cable connector is connected to the detector 14 through the upper conductive post 151 and the upper terminal post 152. The detector 14 then detects part of the circuit in the low-voltage cable. After the detection is completed, the sliding post 153 is slid down, so that the sliding post 153 contacts the lower terminal post 152 and the lower conductive post 151, thus connecting the lower terminal post 152 and the lower conductive post 151. The detector 14 then detects another part of the circuit in the low-voltage line through the lower conductive post 151 and the lower terminal post 152.

[0059] The interface 13 allows the detection device to be connected to the low-voltage circuit. The power connection post 152 and the conductive post 151 allow the low-voltage circuit to be connected to the detector 14, enabling the detector 14 to detect the low-voltage circuit. Furthermore, the conductive post 151 and the power connection post 152, located at the top and bottom, allow the sliding post 153 to slide, enabling the detection of different parts of the low-voltage circuit separately. This improves the versatility of the detection device, reduces the number of devices that personnel need to carry when detecting low-voltage circuits, and reduces the complexity and cost of operation for personnel.

[0060] Furthermore, interface 13 includes two sets of contacts, which can be connected to two sets of contacts in the low-voltage line connector, and the two sets of lines in the low-voltage line connector are connected to the two sets of contacts in the low-voltage line connector.

[0061] Furthermore, detector 14 is existing technology and will not be described in detail.

[0062] like Figure 1 , 2As shown in Figure 8, the sliding column 153 is connected to the drive mechanism 2. The drive mechanism 2 includes three manual components 21, each of which is connected to a corresponding sliding column 153. Each manual component 21 includes a sliding hole 211 opened on the upper side of the housing 11. A push rod 212 is slidably connected in the sliding hole 211. The bottom of the push rod 212 is fixedly connected to the sliding column 153. A first spring 213 is connected between the sliding column 153 and the top wall of the housing 11. The first spring 213 is sleeved on the push rod 212. A fixing rod 214 is fixedly connected to the lower side of the sliding column 153. An iron block 215 is fixedly connected to the bottom end of the fixing rod 214. A first magnetic block 216 is provided on the lower side of the iron block 215. The first magnetic block 216 is fixedly connected to the bottom wall of the housing 11 through a connecting rod 217. A second magnetic block 218 is provided on the lower side of the first magnetic block 216. The second magnetic block 218 is fixedly connected to the bottom wall of the housing 11.

[0063] Specifically, in use, when the first spring 213 is in its natural state, the sliding post 153 is in contact with the upper conductive post 151 and the upper contact post 152. When it is necessary to bring the sliding post 153 into contact with the lower contact post 152 and the conductive post 151, the push rod 212 is pressed down. The push rod 212 moves downward, causing the sliding post 153 to move downward, simultaneously stretching the first spring 213. At the same time, the sliding post 153, through the connecting rod 217, causes the iron block 215 to move downward. When the first magnetic block 216 contacts the side of the iron block 215, the movement stops. Push the push rod 212 down. At this time, the iron block 215 is held in place by the attraction of the first magnetic block 216, so that the conductive post 151 on the lower side is connected to the power receiving post 152 on the lower side. When it is necessary to disconnect the weak current line, continue to press the push rod 212 down, so that the push rod 212 drives the iron block 215 to continue to move down. When the bottom surface of the iron block 215 contacts the second magnetic block 218, stop pushing the push rod 212 down. The iron block 215 remains stationary under the action of the second magnetic block 218, so that the weak current line is disconnected from the detector 14.

[0064] The manual component 21 allows the user to move the sliding column 153 up and down by pressing the push rod 212, thereby switching the upper and lower electrical terminals 152 on and off. The iron block 215, the first magnetic block 216, and the second magnetic block 218 ensure that the position of the sliding column 153 is maintained when switching the upper and lower electrical terminals 152 on and off, facilitating the testing process.

[0065] like Figure 2 , 4As shown in Figures 5, 6, 9, and 10, the drive mechanism 2 further includes an automatic component 22. The automatic component 22 includes a fixed plate 221 fixedly connected to the bottom wall of the housing 11. A motor 222 is fixedly connected to the fixed plate 221. A lead screw 223 is fixedly connected to the output end of the motor 222. A threaded block 224 is threadedly fitted onto the lead screw 223. A sliding rod 225 is fixedly connected to the fixed plate 221. The threaded block 224 is slidably fitted onto the sliding rod 225. An abutment frame 226 is fixedly connected to the bottom surface of the threaded block 224. The abutment frame 226 is in the shape of an inverted trapezoid. An abutment rod 227 is fixedly connected to the iron block 215. The abutment rod 227 contacts the inclined surface of the abutment frame 226.

[0066] Specifically, in use, when the user is at the other end of the low-voltage line and needs to test the low-voltage line, the motor 222 is started remotely. The output end of the motor 222 drives the lead screw 223 to rotate. The rotation of the lead screw 223, in conjunction with the limiting effect of the slide rod 225, causes the threaded block 224 to move along the lead screw 223. When the threaded block 224 moves, it drives the abutment frame 226 to move. The inclined surface of the abutment frame 226 contacts the abutment rod 227, causing the abutment... The connecting rod 227 moves downward, and the abutting rod 227 drives the iron block 215 to move downward. When the iron block 215 contacts the first magnetic block 216, the motor 222 stops rotating. When the user needs to disconnect the weak current circuit for testing, the motor 222 is started, so that the abutting frame 226 continues to move. The abutting frame 226 continues to drive the abutting rod 227 to move downward. When the iron block 215 contacts the second magnetic block 218, the bottom surface of the abutting frame 226 just contacts the abutting rod 227.

[0067] By setting up the automatic component 22, when it is inconvenient for the user to move to the location of the detection device, the user can remotely control the motor 222 to start the motor 222, which drives the lead screw 223 to rotate. This drives the abutment frame 226 to move through the threaded block 224. The abutment frame 226 then drives the iron block 215 to move through the abutment rod 227, thereby realizing the movement of the sliding column 153, which facilitates the detection of weak current lines.

[0068] Furthermore, the first magnetic block 216 and the second magnetic block 218 are electromagnets.

[0069] Specifically, when the iron block 215 needs to be reset, the power supply to the first magnetic block 216 and the second magnetic block 218 is disconnected by remote control, so that the magnetism of the first magnetic block 216 and the second magnetic block 218 disappears, and the iron block 215 is reset under the action of the first spring 213.

[0070] The electromagnets of the first magnetic block 216 and the second magnetic block 218 enable remote control of the reset of the iron block 215, thereby facilitating the detection of weak current circuits.

[0071] Furthermore, electromagnets are existing technology and will not be described in detail.

[0072] like Figure 3 , 6 As shown, a protective mechanism 3 is provided on the side of the housing 11. The protective mechanism 3 is located at the opening 12. The protective mechanism 3 includes two sliding grooves 31 symmetrically opened on the side of the housing 11. A slider 32 is slidably connected in each sliding groove 31. The two sliders 32 extend out of the sliding grooves 31 respectively. A protective plate 33 is fixedly connected to each of the two sliders 32. The protective plate 33 can close the opening 12.

[0073] Specifically, when using the testing device, slide the protective plate 33 upwards. The protective plate 33 drives the slider 32 to slide upwards in the groove 31, so that the opening 12 is exposed, allowing the weak current line connector to be connected to the interface 13. After the testing device is used, slide the protective plate 33 downwards, so that the protective plate 33 drives the slider 32 to slide downwards, and the protective plate 33 closes the interface 13.

[0074] With the protective mechanism 3, the interface 13 can be exposed by sliding the protective plate 33, which facilitates the connection of low-voltage lines. Furthermore, with the protective plate 33, the interface 13 can be sealed after the detection device is used, which slows down the oxidation process of the interface 13 during the storage of the detection device and reduces the entry of dust.

[0075] Furthermore, fixed magnetic blocks are fixedly connected to the upper and lower side walls of the slide groove 31, and the fixed magnetic blocks are magnetically attracted to the slider 32.

[0076] Specifically, during use, when the protective plate 33 moves upward, it drives the slider 32 to move upward, so that the slider 32 is magnetically attracted to the fixed magnetic block on the upper side, thus maintaining the position of the protective plate 33; when the protective plate 33 moves downward, it drives the slider 32 to move downward, so that the slider 32 is magnetically attracted to the fixed magnetic block on the lower side, thus maintaining the position of the protective plate 33.

[0077] By setting the fixed magnetic block, the protective plate 33 can be kept in position when it is opened and closed, which facilitates the opening and closing of the interface 13.

[0078] like Figure 1 As shown, a C-shaped handle is provided on the housing 11, and the handle is fixedly connected to the housing 11.

[0079] Furthermore, the detector 14 is electrically connected to a controller, which is disposed on the top surface of the housing 11 and is fixedly connected to the housing 11.

[0080] like Figure 1 As shown, a circular plate is fixedly connected to the top of the push rod 212.

[0081] like Figure 11 As shown, C-shaped elastic contact pieces are fixedly connected to both ends of the sliding column 153.

[0082] By setting the elastic contact piece, the sliding post 153 can make better contact with the conductive post 151 and the power receiving post 152 during the sliding repositioning process.

[0083] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings.
