Description

Technical Field

[0001] This invention relates to the field of power supply technology, and specifically to a non-intrusive power load identification and monitoring system. Background Technology

[0002] Non-intrusive power load monitoring is a new type of sensor monitoring system that collects and analyzes the total power or current consumed by a user to monitor the power consumption and operating status of each electrical device. Just as human voiceprints and fingerprints are unique biometric features that can be used for individual identification, different types and models of electrical devices also have relatively stable and significant characteristics in the time-series data such as voltage, current, and harmonics generated during operation. These characteristics are called the load imprints of the electrical devices. The load imprints can reflect the unique information of an electrical device's power consumption status during operation, such as voltage, active power waveform, and starting current. The non-intrusive power load monitoring system only sets load detection sensors in the main power supply circuit. The non-intrusive power load identification and monitoring system identifies and monitors the usage of electrical devices in a user's home by recognizing the load imprints of various electrical devices.

[0003] The current number of parking spaces in the community's carport is limited. Some residents on lower floors charge their electric vehicles in the stairwells or by running extension cords, which poses safety hazards and violates fire safety regulations. Meanwhile, residents on higher floors cannot charge their electric vehicles downstairs due to limited space. Therefore, it is necessary to expand the number of parking spaces in the community's carport. During the construction of the new parking spaces, to ensure charging safety, temporary parking spaces will be used for charging electric vehicles. A load identification terminal will be used to monitor the power consumption of the community's carport. Circuit breakers will be used in conjunction with the load identification terminal to disconnect the circuit, ensuring power safety and meeting the temporary charging needs of users.

[0004] Workers typically connect the circuit breaker to the circuit and then connect the circuit breaker to the electrical equipment. Because the usage scenario is temporary power supply, there is no distribution box or other installation location to fix the circuit breaker, so the circuit breaker is exposed to the outside. Workers usually place the circuit breaker on the ground. On the one hand, the circuit breaker and the power line are easy to trip pedestrians, and the load identification terminal and circuit breaker terminal are easy to be damaged. On the other hand, it poses a hidden danger to electrical safety.

[0005] Meanwhile, when electric vehicle owners are supplying power to their equipment through the non-intrusive power load identification and monitoring system, other people can unplug the equipment and plug in their own, affecting the power supply to the staff's equipment and thus harming the interests of the electric vehicle owners, thereby creating limitations in the solution.

[0006] In view of this, in order to overcome the above-mentioned technical problems, the present invention proposes a non-intrusive power load identification and monitoring system, which solves at least one of the above-mentioned technical problems. Summary of the Invention

[0038] like Figures 1 to 5 As shown, the non-intrusive power load identification and monitoring system of the present invention includes:

[0039] Circuit breaker 2; Circuit breaker 2 includes housing 1 and circuit breaker body, and is used to control the opening and closing of the connected circuit;

[0040] Load identification terminal 3; Load identification terminal 3 is installed inside the housing. Load identification terminal 3 is used to identify the type of electrical equipment connected to circuit breaker terminal 2. Load identification terminal 3 and circuit breaker terminal 2 are connected through a transmission line.

[0041] A fixing mechanism 4 is provided on the housing 1;

[0042] The fixing mechanism 4 is used to fix the housing 1;

[0043] The load identification terminal 3 includes a transmission unit 31, a recording unit 32, an acquisition unit 33, and a processing unit 34; the transmission unit 31, the recording unit 32, the acquisition unit 33, and the processing unit 34 transmit data through a transmission line;

[0044] The acquisition unit 33 uses a sensor array as a carrier to acquire the load imprint of the user's electrical equipment.

[0045] The transmission unit 31 uses a data receiving channel, such as a USB channel, as a carrier to receive data information and transmit the information to the recording unit 32;

[0046] The recording unit 32 uses an electronic device as a carrier, such as a recording memory chip, and is used to record the information transmitted by the transmission unit 31.

[0047] The processing unit 34 uses an electronic device as a carrier, such as a processing chip. The processing unit 34 can retrieve information from the recording unit 32. The processing unit 34 is used to compare the load imprint of the user's electrical equipment with the information recorded in the recording unit 32. If the information is the same, the circuit breaker terminal 2 is controlled to continue to be powered.

[0048] Circuit breakers generally consist of a contact system, an arc-extinguishing system, an operating mechanism, a trip unit, and a casing. During a short circuit, according to I = U / R, the circuit resistance decreases, the current increases, and the magnetic field generated by the large current overcomes the counterforce spring, causing the trip unit to activate the operating mechanism, and the switch trips instantaneously. During an overload, according to W = I... 2 R, the circuit power increases, the current through the circuit breaker increases, the heat generation intensifies, and the bimetallic strip deforms to a certain extent to drive the mechanism to move.

[0049] While staff are supplying power to electrical equipment through the non-intrusive power load identification and monitoring system, other personnel can unplug the equipment and plug in their own, affecting the power supply to the staff's equipment and thus harming the staff's interests.

[0050] Therefore, when using this invention, the operator first digitizes the load imprint data such as voltage, active power waveform, and starting current during the operation of the designated electrical equipment. The operator then transmits the digitized load imprint data to the transmission unit 31 via a USB channel. The transmission unit 31 then transmits the load imprint information to the recording unit 32 via a transmission line, where it is recorded and stored. When the user uses the electrical equipment, the acquisition unit 33 acquires the load imprint data of the electrical equipment through a circuit, and then transmits the load imprint data to the transmission line. The signal is sent to the processing unit 34. After receiving the signal, the processing unit 34 retrieves the load imprint signal stored in the recording unit 32 through the transmission line and compares the two. If they are the same, the signal is transmitted to the circuit breaker terminal 2 through the transmission line, so that the circuit breaker terminal 2 remains connected. If they are different, the signal is transmitted to the circuit breaker terminal 2 through the transmission line, so that the circuit breaker terminal 2 remains disconnected. After the circuit breaker terminal disconnects the circuit, when other personnel connect their electrical equipment to the temporary power line, the recording unit 32 does not record the load imprint of the electrical equipment, so it cannot supply power to the electrical equipment and prevent other personnel from stealing electricity.

[0051] The present invention compares the load imprint recorded by the recording unit 32 with the load imprint of the electrical equipment through the processing unit 34, thereby enabling the user to supply power only to specific electrical equipment. At the same time, the load imprint of the specific electrical equipment is transmitted to the recording unit 32 through the transmission unit 31, which can prevent the user from using some non-standard electrical equipment and prevent others from connecting the electrical equipment to temporary power lines, thus improving the safety of the user's electricity use.

[0052] In one embodiment of the present invention, when the processing unit 34 receives information again after the information reception interruption, it controls the circuit breaker terminal 2 to disconnect; the load identification terminal 3 also includes an alarm unit 36; the alarm unit 36 ​​is used to transmit the signal of the circuit breaker terminal 2 disconnecting the circuit to the operator's client; the client is an electronic device, such as a mobile phone;

[0053] In operation, taking the temporary addition of charging piles to electric vehicle sheds or residents installing extension cords to charge their electric vehicles as an example, the property management collects monthly fees for parking spaces and charging, and then numbers the parking spaces for electric vehicles. Personnel paying the fees charge their vehicles in their assigned parking spaces. The property management staff first power on the electric vehicle's charger, then connect the sensor array to the circuit, using the sensor array to acquire the load imprint of the charger. Finally, the load imprint of the charger acquired by the sensor array is transmitted to the transmission unit 31 via a USB interface, and then recorded in the recording unit 32. When another electric vehicle owner unplugs the charger from the charging pile when no one else is around, and then plugs in their own charger to charge their vehicle, the load imprint of the electrical equipment on the charging pile is interrupted, thus triggering a circuit breaker. When the load imprint of the electrical equipment received by the processing unit 34 is also interrupted, the processing unit 34 transmits the interruption information to the circuit breaker terminal 2 through the transmission line, thereby interrupting the power supply to the circuit breaker terminal 2. The alarm unit 36 ​​obtains the circuit connection status of the circuit breaker terminal 2. When the circuit breaker terminal 2 interrupts the circuit, the alarm unit 36 ​​transmits the circuit interruption signal to the client on the staff's mobile phone, thereby triggering an alarm. Then, the community property management personnel go to the site where the invention is used to deal with the electricity theft by other users and manually switch the circuit breaker to restore the circuit connection in time, thereby preventing the electricity use of other users from being affected. When other electric vehicle owners steal electricity, the community property management personnel are notified to handle the situation, protecting the user's rights and experience, thereby preventing the impact on the use of electric vehicles that are charging, and improving the effectiveness of the invention.

[0054] After the expansion of a parking shed in a residential community is completed, this invention can be dismantled and applied to the next parking shed that needs expansion, thus giving the invention market application prospects.

[0055] As one embodiment of the present invention, the load identification terminal 3 includes an identification unit 35; the identification unit 35 is capable of identifying and connecting to mobile phone Bluetooth or wireless signals, and the identification unit 35 is a Bluetooth module.

[0056] During operation, the electric vehicle owner turns on their mobile phone's Bluetooth or Wi-Fi signal, allowing the identification unit 35 to connect with the phone's Bluetooth or Wi-Fi signal. The identification unit 35 then identifies the electric vehicle owner and controls the circuit breaker terminal 2 via the transmission line. When the electric vehicle owner unplugs the fully charged charger and needs to charge another electric vehicle that is out of power, they plug the charger back in. At this point, the load indication detected by the invention is interrupted, but the identification unit 35 controls the circuit breaker terminal 2 to maintain power, ensuring the circuit remains connected. This prevents the load identification terminal 3 from misjudging and disconnecting the circuit when the owner charges another electric vehicle after the first one is fully charged, thus improving the user experience for operators.

[0057] As one embodiment of the present invention, when the processing unit 34 receives information again after a 3-second interruption in receiving information, it controls the circuit breaker terminal 2 to disconnect.

[0058] Taking electric vehicle charging as an example, pulse chargers exist on the market. The charger charges the electric vehicle, and in the final stage of charging, the charger intermittently charges the electric vehicle, so the load imprint generated by the charger is also intermittent. When the processing unit 34 receives information again after a 3-second interruption, it controls the circuit breaker terminal 2 to disconnect. Since the charger pulse interval is less than 3 seconds, this invention prevents the intermittent charging of the charger from being mistakenly judged as other users stealing electricity, thus ensuring the practicality of the invention.

[0059] In one embodiment of the present invention, the fixing mechanism 4 includes a through groove 41 and a fixing block 42; the through groove 41 is located near the bottom of the housing 1 and penetrates the housing 1; the fixing block 42 is a trapezoidal block and the end face with the largest size is fixedly connected to a first elastic band 43; the other end of the first elastic band 43 passes through the first slot 5 of the through groove 41 and is fixedly connected to the groove wall of the through groove 41; the other slot of the through groove 41 is a second slot 6; the housing 1 is provided with an L-shaped groove 44; there are two L-shaped grooves 44, and the two L-shaped grooves 44 are located on both sides of the second slot 6; one end of the two L-shaped grooves 44 is connected to the through groove 41, and the other end penetrates the housing 1; an L-shaped block 45 is slidably connected in the two L-shaped grooves 44; one end of the two L-shaped blocks 45 is located in the through groove 41, and the other end is exposed in the L-shaped groove 44;

[0060] Therefore, when using this invention, the operator first pulls the fixing block 42, then places the invention on one side of a fixed wooden stake or cement pillar, and pulls the fixing block 42 around the wooden stake or cement pillar. The first elastic band 43 is pulled by the fixing block 42 and comes into contact with the wooden stake or cement pillar. The operator then inserts the fixing block 42 into the second slot 6 of the through groove 41, so that the inclined side of the fixing block 42 comes into contact with the L-shaped block 45. Then, under the action of the inclined side, the fixing block 42 pushes the two L-shaped blocks 45 apart, and the L-shaped blocks 45 slide away from the fixing block 42 in the L-shaped groove 44. The fixing block 42 enters the through groove 41. The operator then pushes the two L-shaped blocks 45 towards each other, so that the ends of the two L-shaped blocks 45 located in the through groove 41 come into contact with the end face of the first elastic band 43 fixed to the fixing block 42. The two L-shaped blocks 45 lock the fixing block 42, thereby completing the fixing of the shell 1.

[0061] This invention uses a fixing block 42 with an elastic band 43 wrapped around a cylindrical fixing object, and then inserts the fixing block 42 into the through groove 41 to complete the fixing of the invention. This allows the invention to be temporarily fixed to some cylindrical objects, adapting to the use environment of temporarily adding lines, and facilitating installation and disassembly, thus making it safer for workers when temporarily adding power lines. At the same time, it makes the invention less susceptible to contact, reducing the risk of damage to the load identification terminal 3 and the circuit breaker terminal 2 due to the inability to fix the invention, and improving the effectiveness of the invention.

[0062] In one embodiment of the present invention, a flexible block 49 is fixedly connected to the bottom surface of the housing 1.

[0063] In one embodiment of the present invention, a first locking block 15 is uniformly fixed to the end face of the first elastic band 43; a support groove 7 is provided on the outer side of the housing 1; the support groove 7 is located above the first slot 5 and communicates with the first slot 5; a first spring 16 is fixed to the groove wall of the support groove 7 away from the first slot 5; a support block 8 is fixed to the other end of the first spring 16; the support block 8 slides with the support groove 7 and the support block 8 protrudes from the support groove 7, and the support block 8 can contact the first elastic band 43 and lock it in place.

[0064] In one embodiment of the present invention, a first locking block 15 is disposed on the side of the first elastic band 43 near the bottom of the housing 1; a second locking block 17 is fixedly connected to the groove wall of the through groove 41 near the first groove opening 5; the second locking block 17 can engage with the first locking block 15.

[0065] During operation, the worker first grasps the portion of the support block 8 that protrudes from the support groove 7 and pulls the support block 8 away from the first groove 5. The support block 8 compresses the first spring 16, and at this time, the support block 8 does not contact the first elastic band 43. The worker then pulls the fixing block 42, which moves the first elastic band 43 along with it. The first locking block 15 on the first elastic band 43 contacts the surrounded cylindrical object, thereby increasing the friction between the first elastic band 43 and the cylindrical object. The worker then releases the L-shaped block 45, which enters the through groove 41 under the action of the first spring 16 and pushes the first elastic band 43 toward the second locking block 17, causing the second locking block 17 to lock with the first locking block 15. Finally, the fixing block 42 is inserted into the through groove 41, thus completing the fixing of the invention.

[0066] The present invention uses the engagement between the first locking block 15 and the second locking block 17 to fix the first elastic band 43 at the opening of the through groove 41. This means that when the present invention is fixed, the portion of the first elastic band 43 outside the through groove 41 is stretched, while the portion inside the through groove 41 is not stretched. This changes the length of the first elastic band 43 outside the through groove 41, allowing the first elastic band 43 to adapt to cylindrical objects of different sizes, thereby improving the applicability of the present invention and ensuring its effectiveness.

[0067] In one embodiment of the present invention, the fixing mechanism 4 includes a storage cavity 46; the storage cavity 46 is located at the bottom of the housing 1; a connecting groove 47 is provided on the bottom surface of the housing 1; the connecting groove 47 is located close to the storage cavity 46, and a sliding block 48 is slidably connected to the end of the connecting groove 47 away from the storage cavity 46; the sliding block 48 is triangular prism in shape, and the end of the sliding block 48 close to the storage cavity 46 is conical, and the sliding block 48 can puncture the housing 1 between the connecting groove 47 and the storage cavity 46; the storage cavity 46 stores an adhesive liquid, such as room temperature water-curing adhesive.

[0068] In one embodiment of the present invention, the shell 1 is divided into a first shell 11 and a second shell 12; a storage cavity 46 and a connecting groove 47 are disposed on the second shell 12; a T-shaped groove 13 is provided on the bottom surface of the first shell 11; the second shell 12 is slidably connected to the T-shaped groove 13, and a drainage groove 14 is provided on the bottom surface of the second shell 12; the drainage groove 14 is connected to the connecting groove 47, and the drainage groove 14 is distributed throughout the bottom surface of the second shell 12.

[0069] During operation, the worker places housing 1 on the object to be installed, causing sliding block 48 to contact the object. The worker then presses housing 1, causing sliding block 48 to puncture the second housing 12 between the connecting groove 47 and the storage cavity 46. The room-temperature water-curing adhesive in the storage cavity 46 flows into the drainage groove 14 through the connecting groove 47 and through the gap between sliding block 48 and the connecting groove 47, then flows into the drainage groove 14 and is distributed across the entire bottom surface of the second housing 12. After entering the drainage groove 14, the room-temperature water-curing adhesive comes into contact with moisture in the air, causing it to solidify and adhere to the object within 3-5 seconds, thus bonding the second housing 12 to the object. The material cannot come into contact with air while inside the storage cavity 46, thus preventing it from solidifying. Operators can slide shell 11 to separate it from shell 12, removing shell 11 and the circuit breaker terminal 2 and load identification terminal 3 within it. By puncturing shell 12 between the connecting groove 47 and the storage cavity 46 with sliding block 48, the glue inside the storage cavity 46 can flow out and adhere to shell 12, thus securing the invention. Operators can also slide shell 11 to separate it from shell 12, allowing the invention to adhere to objects, adapting to environments where temporary wiring is added, facilitating installation and disassembly, and improving the overall effectiveness of the invention.

[0075] A fixing mechanism 4 is provided on the housing 1;

[0076] The fixing mechanism 4 is used to fix the housing 1;

[0077] The load identification terminal 3 includes a transmission unit 31, a recording unit 32, an acquisition unit 33, and a processing unit 34; the transmission unit 31, the recording unit 32, the acquisition unit 33, and the processing unit 34 transmit data through a transmission line;

[0078] The acquisition unit 33 uses a sensor array as a carrier to acquire the load imprint of the user's electrical equipment;

[0079] The transmission unit 31 uses a data receiving channel, such as a USB channel, as a carrier to receive data information and transmit the information to the recording unit 32;

[0080] The recording unit 32 uses an electronic device as a carrier, such as a recording memory chip, and is used to record the information transmitted by the transmission unit 31.

[0081] The recording unit 32 uses an electronic device as a carrier, such as a recording storage chip. The processing unit 34 can retrieve the information in the recording unit 32. The processing unit 34 is used to compare the load imprint of the user's electrical equipment with the information recorded in the recording unit 32. If the information is the same, the circuit breaker terminal 2 is controlled to continue to be powered.

[0082] Circuit breakers generally consist of a contact system, an arc-extinguishing system, an operating mechanism, a trip unit, and a casing. During a short circuit, according to I = U / R, the circuit resistance decreases, the current increases, and the magnetic field generated by the large current overcomes the counterforce spring, causing the trip unit to activate the operating mechanism, and the switch trips instantaneously. During an overload, according to W = I... 2 R, the circuit power increases, the current through the circuit breaker increases, the heat generation intensifies, and the bimetallic strip deforms to a certain extent to drive the mechanism to move.

[0083] While staff are supplying power to electrical equipment through the non-intrusive power load identification and monitoring system, other personnel can unplug the equipment and plug in their own, affecting the power supply to the staff's equipment and thus harming the staff's interests.

[0084] Therefore, when using this invention, the operator first digitizes the load imprint data such as voltage, active power waveform, and starting current during the operation of the designated electrical equipment. The operator then transmits this digitized load imprint data to the transmission unit 31 via a USB channel. The transmission unit 31 then transmits the load imprint information to the recording unit 32 via a transmission line, where it is recorded and stored. When the user uses the electrical equipment, the acquisition unit 33 acquires the load imprint of the electrical equipment through a circuit and transmits it to the processing unit 34 via a transmission line. The processing unit 34 receives the data and retrieves the load imprint signal stored in the recording unit 32 via the transmission line. The two are compared; if they match, the signal is transmitted to the circuit breaker terminal 2 via the transmission line, keeping the circuit breaker terminal 2 connected; otherwise, the signal is transmitted to the circuit breaker terminal 2 via the transmission line, keeping the circuit breaker terminal 2 disconnected. When other personnel connect their electrical equipment to a temporary power line, the recording unit 32 does not record the load imprint of the electrical equipment, thus preventing power supply to the equipment and preventing electricity theft.

[0085] The present invention compares the load imprint recorded by the recording unit 32 with the load imprint of the electrical equipment through the processing unit 34, thereby enabling the user to supply power only to specific electrical equipment. At the same time, the load imprint of the specific electrical equipment is transmitted to the recording unit 32 through the transmission unit 31, which can prevent the user from using some non-standard electrical equipment and prevent others from connecting the electrical equipment to temporary power lines, thus improving the safety of the user's electricity use.

[0086] In this embodiment, when the processing unit 34 receives information again after the information reception interruption, it controls the circuit breaker terminal 2 to disconnect; the load identification terminal 3 also includes an alarm unit 36; the alarm unit 36 ​​is used to transmit the signal of the circuit breaker terminal 2 disconnecting the circuit to the operator's client; the client is an electronic device, such as a mobile phone;

[0087] In operation, taking the temporary addition of charging piles to electric vehicle sheds or residents installing extension cords to charge their electric vehicles as an example, the property management collects monthly fees for parking spaces and charging, and then numbers the parking spaces for electric vehicles. Personnel paying the fees charge their vehicles in their assigned parking spaces. The property management staff first power on the electric vehicle's charger, then connect the sensor array to the circuit, using the sensor array to acquire the load imprint of the charger. Finally, the load imprint of the charger acquired by the sensor array is transmitted to the transmission unit 31 via a USB interface, and then recorded in the recording unit 32. When another electric vehicle owner unplugs the charger from the charging pile when no one else is around, and then plugs in their own charger to charge their vehicle, the load imprint of the electrical equipment on the charging pile is interrupted, thus triggering a circuit breaker. When the load imprint of the electrical equipment received by the processing unit 34 is also interrupted, the processing unit 34 transmits the interruption information to the circuit breaker terminal 2 through the transmission line, thereby interrupting the power supply to the circuit breaker terminal 2. The alarm unit 36 ​​obtains the circuit connection status of the circuit breaker terminal 2. When the circuit breaker terminal 2 interrupts the circuit, the alarm unit 36 ​​transmits the circuit interruption signal to the client on the staff's mobile phone, thereby triggering an alarm. Then, the community property management personnel go to the site where the invention is used to deal with the electricity theft by other users and manually switch the circuit breaker to restore the circuit connection in time, thereby preventing the electricity use of other users from being affected. When other electric vehicle owners steal electricity, the community property management personnel are notified to handle the situation, protecting the user's rights and experience, thereby preventing the impact on the use of electric vehicles that are charging, and improving the effectiveness of the invention.

[0088] After the expansion of a parking shed in a residential community is completed, this invention can be dismantled and applied to the next parking shed that needs expansion, thus giving the invention market application prospects.

[0089] As one embodiment of the present invention, the load identification terminal 3 includes an identification unit 35; the identification unit 35 is capable of identifying and connecting to mobile phone Bluetooth or wireless signals, and the identification unit 35 is a Bluetooth module.

[0090] During operation, the electric vehicle owner turns on their mobile phone's Bluetooth or Wi-Fi signal, allowing the identification unit 35 to connect with the phone's Bluetooth or Wi-Fi signal. The identification unit 35 then identifies the electric vehicle owner and controls the circuit breaker terminal 2 via the transmission line. When the electric vehicle owner unplugs the fully charged charger and needs to charge another electric vehicle that is out of power, they plug the charger back in. At this point, the load indication detected by the invention is interrupted, but the identification unit 35 controls the circuit breaker terminal 2 to maintain power, ensuring the circuit remains connected. This prevents the load identification terminal 3 from misjudging and disconnecting the circuit when the owner charges another electric vehicle after the first one is fully charged, thus improving the user experience for operators.

[0091] In this embodiment, when the processing unit 34 receives information again after a 3-second interruption in receiving information, it controls the circuit breaker terminal 2 to disconnect.

[0092] Taking electric vehicle charging as an example, pulse chargers exist on the market. The charger charges the electric vehicle, and in the final stage of charging, the charger intermittently charges the electric vehicle, so the load imprint generated by the charger is also intermittent. When the processing unit 34 receives information again after a 3-second interruption, it controls the circuit breaker terminal 2 to disconnect. Since the charger pulse interval is less than 3 seconds, this invention prevents the intermittent charging of the charger from being mistakenly judged as other users stealing electricity, thus ensuring the practicality of the invention.

[0093] Example 2:

[0094] The difference from Example 1 is as follows:

[0095] In this embodiment, the fixing mechanism 4 includes a through groove 41 and a fixing block 42; the through groove 41 is located near the bottom of the housing 1 and penetrates the housing 1; the fixing block 42 is a trapezoidal block and the largest end face is fixedly connected to a first elastic band 43; the other end of the first elastic band 43 passes through the first slot 5 of the through groove 41 and is fixedly connected to the groove wall of the through groove 41; the other slot of the through groove 41 is a second slot 6; the housing 1 is provided with an L-shaped groove 44; there are two L-shaped grooves 44, and the two L-shaped grooves 44 are located on both sides of the second slot 6; one end of the two L-shaped grooves 44 is connected to the through groove 41, and the other end penetrates the housing 1; an L-shaped block 45 is slidably connected in the two L-shaped grooves 44; one end of the two L-shaped blocks 45 is located in the through groove 41, and the other end is exposed in the L-shaped groove 44;

[0096] Therefore, when using this invention, the operator first pulls the fixing block 42, then places the invention on one side of a fixed wooden stake or cement pillar, and pulls the fixing block 42 around the wooden stake or cement pillar. The first elastic band 43 is pulled by the fixing block 42 and comes into contact with the wooden stake or cement pillar. The operator then inserts the fixing block 42 into the second slot 6 of the through groove 41, so that the inclined side of the fixing block 42 comes into contact with the L-shaped block 45. Then, under the action of the inclined side, the fixing block 42 pushes the two L-shaped blocks 45 apart, and the L-shaped blocks 45 slide away from the fixing block 42 in the L-shaped groove 44. The fixing block 42 enters the through groove 41. The operator then pushes the two L-shaped blocks 45 towards each other, so that the ends of the two L-shaped blocks 45 located in the through groove 41 come into contact with the end face of the first elastic band 43 fixed to the fixing block 42. The two L-shaped blocks 45 lock the fixing block 42, thereby completing the fixing of the shell 1.

[0097] This invention uses a fixing block 42 with an elastic band 43 wrapped around a cylindrical fixing object, and then inserts the fixing block 42 into the through groove 41 to complete the fixing of the invention. This allows the invention to be temporarily fixed to some cylindrical objects, adapting to the use environment of temporarily adding lines, and facilitating installation and disassembly, thus making it safer for workers when temporarily adding power lines. At the same time, it makes the invention less susceptible to contact, reducing the risk of damage to the load identification terminal 3 and the circuit breaker terminal 2 due to the inability to fix the invention, and improving the effectiveness of the invention.

[0098] In this embodiment, a flexible block 49 is fixedly connected to the bottom surface of the housing 1.

[0099] In this embodiment, a first locking block 15 is uniformly fixed to the end face of the first elastic band 43; a support groove 7 is provided on the outer side of the housing 1; the support groove 7 is located above the first slot 5 and communicates with the first slot 5; a first spring 16 is fixed to the groove wall of the support groove 7 away from the first slot 5; a support block 8 is fixed to the other end of the first spring 16; the support block 8 slides with the support groove 7 and the support block 8 protrudes from the support groove 7, and the support block 8 can contact the first elastic band 43 and lock it.

[0100] In this embodiment, the first locking block 15 is disposed on the side of the first elastic band 43 near the bottom of the housing 1; the second locking block 17 is fixedly connected to the groove wall of the through groove 41 near the first groove opening 5; the second locking block 17 can engage with the first locking block 15.

[0101] During operation, the worker first grasps the portion of the support block 8 that protrudes from the support groove 7 and pulls the support block 8 away from the first groove 5. The support block 8 compresses the first spring 16, and at this time, the support block 8 does not contact the first elastic band 43. The worker then pulls the fixing block 42, which moves the first elastic band 43 along with it. The first locking block 15 on the first elastic band 43 contacts the surrounded cylindrical object, thereby increasing the friction between the first elastic band 43 and the cylindrical object. The worker then releases the L-shaped block 45, which enters the through groove 41 under the action of the first spring 16 and pushes the first elastic band 43 toward the second locking block 17, causing the second locking block 17 to lock with the first locking block 15. Finally, the fixing block 42 is inserted into the through groove 41, thus completing the fixing of the invention.

[0102] The present invention uses the engagement between the first locking block 15 and the second locking block 17 to fix the first elastic band 43 at the opening of the through groove 41. This means that when the present invention is fixed, the portion of the first elastic band 43 outside the through groove 41 is stretched, while the portion inside the through groove 41 is not stretched. This changes the length of the first elastic band 43 outside the through groove 41, allowing the first elastic band 43 to adapt to cylindrical objects of different sizes, thereby improving the applicability of the present invention and ensuring its effectiveness.

[0103] Example 3:

[0104] The difference from Example 1 is as follows:

[0105] In this embodiment, the fixing mechanism 4 includes a storage cavity 46; the storage cavity 46 is located at the bottom of the housing 1; a connecting groove 47 is provided on the bottom surface of the housing 1; the connecting groove 47 is located close to the storage cavity 46, and a sliding block 48 is slidably connected to the end of the connecting groove 47 away from the storage cavity 46; the sliding block 48 is triangular prism in shape, and the end of the sliding block 48 close to the storage cavity 46 is conical, and the sliding block 48 can puncture the housing 1 between the connecting groove 47 and the storage cavity 46; the storage cavity 46 stores an adhesive liquid, such as room temperature water-curing adhesive.

[0106] In this embodiment, the shell 1 is divided into a first shell 11 and a second shell 12; the storage cavity 46 and the connecting groove 47 are disposed on the second shell 12; a T-shaped groove 13 is provided on the bottom surface of the first shell 11; the second shell 12 is slidably connected to the T-shaped groove 13, and a drainage groove 14 is provided on the bottom surface of the second shell 12; the drainage groove 14 is connected to the connecting groove 47, and the drainage groove 14 is distributed throughout the bottom surface of the second shell 12;

[0107] During operation, the worker places housing 1 on the object to be installed, causing sliding block 48 to contact the object. The worker then presses housing 1, causing sliding block 48 to puncture the second housing 12 between the connecting groove 47 and the storage cavity 46. The room-temperature water-curing adhesive in the storage cavity 46 flows into the drainage groove 14 through the connecting groove 47 and through the gap between sliding block 48 and the connecting groove 47, then flows into the drainage groove 14 and is distributed across the entire bottom surface of the second housing 12. After entering the drainage groove 14, the room-temperature water-curing adhesive comes into contact with moisture in the air, causing it to solidify and adhere to the object within 3-5 seconds, thus bonding the second housing 12 to the object. The material cannot come into contact with air while inside the storage cavity 46, thus preventing it from solidifying. Operators can slide shell 11 to separate it from shell 12, removing shell 11 and the circuit breaker terminal 2 and load identification terminal 3 within it. By puncturing shell 12 between the connecting groove 47 and the storage cavity 46 with sliding block 48, the glue inside the storage cavity 46 can flow out and adhere to shell 12, thus securing the invention. Operators can also slide shell 11 to separate it from shell 12, allowing the invention to adhere to objects, adapting to environments where temporary wiring is added, facilitating installation and disassembly, and improving the overall effectiveness of the invention.
