Description

Technical Field

[0001] The invention relates to the technical field of electric energy meter scrapping devices, and more specifically, to a meter destroying device. Background Art

[0002] With the rapid development of the economy, people's demand for electricity is becoming more and more urgent, and power companies have higher and higher requirements for the measurement and management of electricity meters. The original traditional mechanical meters and electronic electricity meters need to be replaced. In addition, in order to ensure the accuracy and fairness of electricity metering and promote the intelligent development of power detection, power metering instruments need to be continuously upgraded and transformed as the State Grid's digitalization work continues to advance. Meters that do not meet the operating conditions must be scrapped compulsorily, and the storage time of scrapped assets in the warehouse should not be too long.

[0003] Usually, the electric energy meters to be scrapped need to be applied for by the marketing department of the local power supply company, collected by the material department, and destroyed by destructive means. The on-site supervision and photo taking by the material, marketing, and supervision department personnel are required to ensure that the meters are completely destroyed to prevent them from entering the market.

[0004] Improper handling of old meters will lead to the following problems: (1) Scrapped electricity meters flow back into the market, causing management or market confusion; (2) Secondary use or overdue use poses serious safety hazards and is not conducive to the stable operation of the power system; (3) Waste meter components contain a variety of harmful substances, which will cause serious environmental pollution; (4) If the information processing is not thorough, it will not meet the measurement asset management requirements.

[0005] However, the current methods for recycling and processing waste electricity meters in power collective enterprises mostly use traditional extensive recycling methods such as crushing, rolling, and high-temperature melting. Not only can they not efficiently achieve material recycling, resulting in waste of resources, but the processing process is also prone to secondary pollution such as dust, waste liquid, and waste. Once many toxic components are not treated or treated improperly, they will cause serious pollution to the soil, groundwater and air.

[0006] In order to prevent environmental pollution and ensure that each meter is completely scrapped, that is, loses its metering function, a handheld electric drill is used to drill holes in a purely manual manner, and each scrapped electric energy meter needs to be drilled multiple times. Due to the huge number of scrapped electric energy meters due to rotation and failure every year, the process requires multiple disassembly and assembly, which is repetitive and time-consuming, labor-intensive, and very inefficient.

[0007] Chinese patent publication number CN108326005A, publication date July 27, 2018, the name of the invention is electric energy meter destruction device, the application discloses an electric energy meter destruction device, and discloses the following technical features: including a conveyor belt for conveying electric energy meters, the conveyor belt is provided with two stations along the direction of movement, namely, an equipment destruction station and a shooting station; a first sensor is provided on the side of the equipment destruction station; a first push cylinder that can move along the lateral direction of the conveyor belt is provided on the side of the equipment destruction station; an electric drill that can be driven by a driving device to move vertically is provided above the equipment destruction station, and the electric drill can be driven by the driving device to move toward the electric energy meter entering the equipment destruction station on the conveyor belt, and a shooting module is provided above the shooting station; a third sensor is provided on the side of the shooting station.

[0008] Although the above patent application is capable of automatically destroying the electric energy meter, it does have the following deficiencies: (1) During the destruction process, only one electric energy meter can be destroyed at a time, which makes the efficiency of destroying the electric energy meter very low; (2) In the process of destroying the electric energy meter, the key parts of the electric energy meter containing harmful substances such as the liquid crystal and electrolytic capacitor are easily damaged, causing environmental pollution.

[0009] The Chinese patent publication number is CN112405698A, and the publication date is February 26, 2021. The name of the invention is "Electricity meter scrapping treatment device". The application discloses an electric energy meter scrapping treatment device and discloses the following technical features, including a cabinet, an electric meter storage box, an electric meter storage box carrier for carrying the electric meter storage box, a Y-axis servo component for driving the electric meter storage box carrier to move forward and backward, a drilling component for drilling and damaging, a camera component for taking pictures of the electric energy meter before and after damage, and a driving device for drilling. The drilling assembly and the camera assembly implement the X-axis servo assembly and the Z-axis servo assembly for left-right and up-down movement, and the electronic control assembly for the electrical main control; a protective cover is fixedly provided on the upper end surface of the middle rear part of the cabinet, and two mounting brackets are fixedly provided on the upper end surface of the rear part of the cabinet inside the protective cover, the X-axis servo assembly is fixed on the two mounting brackets, the Z-axis servo assembly is arranged on the X-axis servo assembly, the drilling assembly and the camera assembly are arranged on the Z-axis servo assembly, and a passage for the electric meter storage box is provided between the front end surface of the protective cover and the upper end surface of the cabinet.

[0010] In the above application, although the electric energy meters can be processed in batches by setting up an electric energy meter storage box, there are indeed the following deficiencies: (1) Each time the electric energy meter is processed, it is necessary to put the electric energy meter into the electric energy meter storage box and take the damaged electric energy meter out of the electric energy meter storage box, which makes the operation very cumbersome; (2) During the destruction process, the drill bit is driven by the servo component to move, and the electric energy meters in the electric energy meter storage box are destroyed one by one in turn, which has the disadvantage of low efficiency in destroying the electric energy meters; (3) In the process of destroying the electric energy meter, the key parts of the electric energy meter containing harmful substances, such as the liquid crystal and electrolytic capacitor, are easily damaged, which is not conducive to green recycling.

[0057] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: Reference Figure 1 to Figure 2 As shown, a meter destruction device includes a conveying device, along the conveying direction of the conveying device, an identification device and a destruction box 3 are sequentially arranged, and both the identification device and the destruction box 3 are provided with position sensors for detecting the position of the box.

[0058] The conveying device includes a front conveying device 11, a middle conveying device 12 and a rear conveying device 13, which are independently controlled by a PLC control box. The identification device is arranged above the front conveying device 11; the middle conveying device 12 is arranged in the destruction box 3.

[0059] The conveying device is configured as a front conveying device 11, a middle conveying device 12 and a rear conveying device 13, and is independently controlled by a PLC control box, so that the identification device and the destruction box 3 can work independently.

[0060] The front conveying device 11 and the rear conveying device 13 are conveyor belt devices, and the middle conveying device 12 includes a plurality of electric rollers 121 .

[0061] The electric roller 121 is combined with a position sensor and a PLC circuit control, so that the position of the box can be more accurate when it moves on the electric roller 121. The front conveying device 11 and the rear conveying device 13 are conveyor belt devices, which reduces the manufacturing cost compared to using all electric rollers 121.

[0062] The identification device includes an identification box 2, and the identification box 2 is provided with swing plates 21 on both sides along the direction of the front conveying device 11. The identification box 2 has a built-in RFID reader and antenna, LED light and camera; the RFID reading device can read and record the identity information of a whole box of meters (single-phase 5*7=35, three-phase 5*2=10), and the camera mainly performs image recognition on the whole box of meters to determine whether it is single-phase or three-phase, whether there are any errors in quantity and arrangement, etc.

[0063] In this embodiment, an ultra-high frequency RFID reader is mainly used to identify the RFID identity information tag built into the meter through the RFID antenna, and the read RFID identity information is imported into the database to form a statistical table and a record to ensure that it can be verified.

[0064] The destruction box 3 destroys the meter; a single-phase meter destruction device 4 and a three-phase meter destruction device 5 are sequentially arranged in the destruction box 3, and both the single-phase meter destruction device 4 and the three-phase meter destruction device 5 are provided with a position sensor for detecting the position of the box.

[0065] After the camera determines whether the whole box of meters is single-phase or three-phase by image recognition, the box is transmitted to the destruction box 3. The transmission device 12 positions the box to the position of the single-phase meter destruction device 4 or the three-phase meter destruction device 5 based on the image recognition information.

[0066] The three-phase meter destroying device 5 and the single-phase meter destroying device 4 both include a lifting device 6 and a destroying assembly 7 , and the destroying assembly 7 includes a plurality of destroying parts. The lifting device 6 is fixedly arranged on the frame of the destroying box 3 .

[0067] In this embodiment, the lifting device 6 is configured as a hydraulic cylinder, which has the characteristics of stable operation and strong driving force.

[0068] Auxiliary guide devices are provided on both sides of the hydraulic cylinder, and the auxiliary guide devices include guide sleeves 61 and guide columns 62 arranged on both sides of the hydraulic cylinder. The guide sleeves 61 are fixedly arranged on the frame, and the guide columns 62 are slidably arranged in the guide sleeves 61. The lower ends of the guide columns 62 are fixedly connected to the destruction assembly 7.

[0069] In this embodiment, the destruction assembly 7 is configured to include a mounting plate 71 and a drill bit 72. The movable end of the hydraulic cylinder is fixedly connected to the mounting plate 71 so as to drive the mounting plate 71 to move up and down. A number of drill bits 72 are arranged in parallel on the mounting plate 71.

[0070] When single-phase meters are placed in the box, 5*7=35 single-phase meters are placed. Therefore, in this embodiment, 35 drill bits 72 are set on the mounting plate 71 of the single-phase meter destruction device 4. The 35 drill bits 72 are arranged regularly, so that when the mounting plate 71 moves downward, each drill bit 72 is positioned just to act on the metering sampling module of the single-phase meter, so that the meter is destroyed to prevent it from returning to the market.

[0071] When three-phase meters are placed in the box, 2*5=10 three-phase meters are placed. Therefore, in this embodiment, 10 drill bits 72 are set on the mounting plate 71 of the three-phase meter destruction device 5. The 10 drill bits 72 are arranged regularly, so that when the mounting plate 71 moves downward, each drill bit 72 is positioned just to act on the metering sampling module of the two-phase meter, so that the meter is destroyed to prevent it from returning to the market; at the same time, it can avoid damage to other key parts containing harmful substances such as liquid crystals and electrolytic capacitors to prevent environmental pollution.

[0072] A blocking cover 74 is provided at the lower end of the mounting plate 71, and the blocking cover 74 spans across both sides of the conveying device in the width direction; a plurality of drill holes 741 cooperating with the drill bit 72 are penetrated through the blocking cover 74, and the drill bit 72 acts on the meter through the drill holes 741.

[0073] By providing the drill hole 741, after the meter is destroyed, the drill bit 72 can be prevented from lifting the meter, so that the destroyed meter parts are completely retained in the box.

[0074] The working principle of this embodiment is as follows: the box with the meters is placed on the front conveying device 11, and the front conveying device 11 conveys the box to the identification box 2. The camera mainly performs image recognition and judgment on the whole box of meters to determine whether it is a single-phase meter or a three-phase meter, and whether there is any error in the number and arrangement of the boxes. When the number in the box is incomplete or the meters in the box are placed in the wrong position, an alarm will be triggered to remind the staff to check the placement of the meters in the box; when there is no error in the number and placement of the meters in the box, it will enter the destruction box 3. According to the image recognition situation, the destruction box 3 is transported by the middle conveying device 12 to the bottom of the mounting plate 71 of the single-phase meter destruction device 4 or the three-phase meter destruction device 5, and then the hydraulic cylinder drives the mounting plate 71 to move downward, and the drill bit 72 passes through the drill hole 741 to destroy the metering sampling module of the meter. After the destruction is complete, the hydraulic cylinder drives the mounting plate 71 to move upward, so that the drill bit 72 is pulled out of the meter; then the destroyed electric energy meter in the box is transmitted out through the middle conveying device 12 and the rear conveying device 13. The destruction of the meter is completed. All the controls in this embodiment are completed by PLC control technology, which belongs to the prior art and will not be repeated here; the relevant sensors also belong to the prior art.

[0077] The conveying device is configured as a front conveying device 11, a middle conveying device 12 and a rear conveying device 13, and is independently controlled by a PLC control box, so that the identification device and the destruction box 3 can work independently.

[0078] The front conveying device 11 and the rear conveying device 13 are conveyor belt devices, and the middle conveying device 12 includes a plurality of electric rollers 121 .

[0079] The electric roller 121 is combined with a position sensor and a PLC circuit control, so that the position of the box can be more accurate when it moves on the electric roller 121.

[0080] The identification device includes an identification box 2, and the identification box 2 is provided with swing plates 21 on both sides along the direction of the front conveying device 11. The identification box 2 has a built-in RFID reader and antenna, LED light and camera; the RFID reading device can read and record the identity information of a whole box of meters (single-phase 5*7=35, three-phase 5*2=10), and the camera mainly performs image recognition on the whole box of meters to determine whether it is single-phase or three-phase, whether there are any errors in quantity and arrangement, etc.

[0081] In this embodiment, an ultra-high frequency RFID reader is mainly used to identify the RFID identity information tag built into the meter through the RFID antenna, and the read RFID identity information is imported into the database to form a statistical table and a record to ensure that it can be verified.

After the destruction is complete, the hydraulic cylinder drives the mounting plate 71 to move upward, so that the drill bit 72 is pulled out of the meter; then, the longitudinal auxiliary clamping device 9 and the transverse auxiliary clamping device 8 return to their original positions; then, the damaged electric energy meter in the box is transmitted out through the middle transmission device 12 and the rear transmission device 13.

[0146] When three-phase meters are placed in the box, 2*5=10 three-phase meters are placed. Therefore, in this embodiment, two cutters 73 are set on the mounting plate 71 of the three-phase meter destruction device 5. The two cutters are arranged regularly so that when the mounting plate 71 moves downward, the position of each cutter 73 just acts on the metering sampling module of the two-phase meter, so that the meter is destroyed to prevent it from returning to the market; at the same time, it can avoid damage to other key parts containing harmful substances such as liquid crystals and electrolytic capacitors to prevent environmental pollution.

[0149] In order to make the clamping more stable, the three-phase meter destroying device 5 and the single-phase meter destroying device 4 are both provided with a transverse auxiliary clamping device 8 and a longitudinal auxiliary clamping device 9.

[0150] Reference Figure 5 and Figure 6 As shown, the transverse auxiliary clamping device 8 is arranged on the transverse auxiliary clamping device mounting frame 22, and the transverse auxiliary clamping device 8 includes a transverse driving device and two clamping plate assemblies 82; the two clamping plate assemblies 82 are respectively arranged on both sides of the width direction of the conveying device, and the driving device drives the two clamping plate assemblies 82 to move closer to or away from each other.

[0151] The transverse driving device is provided with a driving gear, and the clamping plate assembly 82 includes a transmission rack 824. The transmission racks 824 of the two clamping plate assemblies 82 are meshed on both sides of the driving gear. The transverse driving device is a driving motor 81; the driving motor 81 is fixedly arranged on the transverse auxiliary clamping device mounting frame 22.

[0152] The clamping plate assembly 82 includes a clamping plate base plate 821 , on which a clamping plate strip 822 is arranged. The clamping plate strip 822 is passed through the gap between the electric rollers 121 , and a clamping plate is fixedly arranged on the clamping plate strip 822 , and the clamping plate is parallel to the movement direction of the middle conveying device 12 .

[0153] Two transverse slide rails 83 are arranged in the width direction of the conveying device, and the two transverse slide rails 83 are arranged on the transverse auxiliary clamping device mounting frame 22. Transverse guide blocks 84 cooperating with the transverse slide rails 83 are arranged on both sides of the clamping plate assembly 82.

[0154] Through the cooperation of the transverse guide rail and the transverse guide block 84, the clamping plate assembly 82 is more stable during the movement of moving away and approaching.

[0155] An abutment device 85 is provided on the other side of the transmission rack 824 that is meshed with the transmission gear, and the abutment device 85 abuts against the transmission rack 824 .

[0156] The abutment device 85 can be abutted by an abutment block. In this embodiment, the abutment device 85 includes an abutment column 851 . An abutment bearing 852 is provided on the abutment column 851 . The abutment bearing 852 abuts against the transmission rack 824 .

[0157] The driving motor 81 drives the driving gear to rotate, so that the transmission rack 824 can be driven to move, so that the transmission rack 824 drives the clamping plate assemblies 82 to move closer to or away from each other; therefore, before the meter is damaged, the clamping plate assemblies 82 are controlled to move closer to each other, so that the clamping plates abut against both sides of the box in the width direction, thereby clamping the box, so as to prevent the box from being deformed when the meter is damaged, and to prevent the meter from moving, so as to accurately damage the meter's metering sampling module.

[0158] Reference Figure 7 As shown, the longitudinal auxiliary clamping device 9 includes a fixing plate 93 fixedly arranged at both ends of the length square of the mounting plate 71, the upper edge of the fixing plate 93 is fixedly connected to the mounting plate 71, and a clamping plate 94 is arranged on the fixing plate 93, and the clamping plate 94 is arranged on one side of the facing surface of the two fixing plates 93; the clamping plate 94 can approach or move away from the fixing plate 93; the facing surfaces of the two clamping plates 94 are sequentially provided with a first guide surface 941 and a clamping surface 942 from bottom to top. When the clamping plate 94 is located above the box body, the edges of the two ends of the box body in the length direction correspond to the first guide surface 941 above.

[0159] A fixing hole 931 is provided through the fixing plate 93 near the lower edge. In this embodiment, three fixing holes 931 are provided.

A clamping spring 95 is sleeved on the fixing column 943, and the clamping spring 95 abuts between the fixing plate 93 and the clamping plate 94.

[0160] In order to prevent the fixing column 943 from being disengaged from the fixing hole 931 , a limiting head 944 is provided at one end of the fixing column 943 away from the clamping plate 94 .

[0161] Therefore, when the mounting plate 71 moves downward and the cutter 73 acts on the meter, the edge of the box contacts the first guide surface 941 and the clamping surface 942 in sequence. When the cutter 73 damages the meter, the clamping surface 942 abuts against the side surfaces at both ends of the length direction of the box through the force of the clamping spring 95. The side surfaces at both ends of the length direction of the box are abutted by the clamping plate 94, which can effectively prevent the box from being deformed. In the longitudinal auxiliary clamping device 9 in the third embodiment, since the longitudinal baffle 92 has a certain gap between the longitudinal baffle 92 and the box body when it abuts against the box body, the clamping effect on the box body is not very good. Therefore, compared with the structure in the third embodiment, the longitudinal auxiliary clamping device 9 in this embodiment can make the clamping plate 94 abut against the two ends of the box body in the length direction through the clamping spring 95, so as to prevent the box body from deforming better.

[0162] Therefore, through the cooperation of the longitudinal auxiliary clamping device 9 and the transverse auxiliary clamping device 8, when the meter is damaged, a clamping effect can be played on all sides of the box, and the box can remain stable, so that the box can be prevented from being deformed when the meter is damaged, and the meter can be prevented from moving, so that the metering sampling module of the meter can be accurately destroyed.

[0163] The working principle of this embodiment is as follows: the box containing the meters is placed on the front conveying device 11, and the front conveying device 11 conveys the box to the identification box 2. The camera mainly performs image recognition and judgment on the whole box of meters to determine whether it is a single-phase meter or a three-phase meter, and whether there are any errors in the number and arrangement of the boxes. When the number in the box is incomplete or the meters in the box are placed in the wrong position, an alarm will be triggered to remind the staff to check the placement of the meters in the box; when there is no error in the number and placement of the meters in the box, it will enter the destruction box 3. The destruction box 3 will be transported to the single-phase meter destruction device 4 or the three-phase meter destruction device according to the image recognition situation by the middle conveying device 12. 5, and then the two sides of the box width direction are clamped by the cooperation of the horizontal auxiliary clamping device 8, and then the hydraulic cylinder drives the mounting plate 71 to move downward, and the cutter 73 passes through the cutter groove 742 to destroy the metering sampling module of the meter. In the process of destroying the meter, the longitudinal auxiliary clamping device 9 clamps the two ends of the box length direction; after the destruction is complete, the hydraulic cylinder drives the mounting plate 71 to move upward, so that the drill bit 72 is pulled out of the meter; then, the longitudinal auxiliary clamping device 9 and the horizontal auxiliary clamping device 8 return to their original positions; then, the damaged electric energy meter in the box is transmitted out through the middle transmission device 12 and the rear transmission device 13. Complete the destruction of the meter. All the controls in this embodiment are completed by PLC control technology, which belongs to the prior art and will not be repeated here; related sensors also belong to the prior art.

[0165] The conveying device includes a front conveying device 11, a middle conveying device 12 and a rear conveying device 13, which are independently controlled by a PLC control box. The identification device is arranged above the front conveying device 11; the middle conveying device 12 is arranged in the destruction box 3.

[0166] The conveying device is configured as a front conveying device 11, a middle conveying device 12 and a rear conveying device 13, and is independently controlled by a PLC control box, so that the identification device and the destruction box 3 can work independently.

[0167] The front conveying device 11 and the rear conveying device 13 are conveyor belt devices, and the middle conveying device 12 includes a plurality of electric rollers 121 .

[0168] The electric roller 121 is combined with a position sensor and a PLC circuit control, so that the position of the box can be more accurate when it moves on the electric roller 121. The front conveying device 11 and the rear conveying device 13 are conveyor belt devices, which reduces the manufacturing cost compared to using all electric rollers 121.

[0169] The identification device includes an identification box 2, and the identification box 2 is provided with swing plates 21 on both sides along the direction of the front conveying device 11. The identification box 2 has a built-in RFID reader and antenna, LED light and camera; the RFID reading device can read and record the identity information of a whole box of meters (single-phase 5*7=35, three-phase 5*2=10), and the camera mainly performs image recognition on the whole box of meters to determine whether it is single-phase or three-phase, whether there are any errors in quantity and arrangement, etc.

[0170] In this embodiment, an ultra-high frequency RFID reader is mainly used to identify the RFID identity information tag built into the meter through the RFID antenna, and the read RFID identity information is imported into the database to form a statistical table and a record to ensure that it can be verified.

[0171] The destruction box 3 destroys the meter; a single-phase meter destruction device 4 and a three-phase meter destruction device 5 are sequentially arranged in the destruction box 3, and both the single-phase meter destruction device 4 and the three-phase meter destruction device 5 are provided with a position sensor for detecting the position of the box.

[0172] After the camera determines whether the whole box of meters is single-phase or three-phase by image recognition, the box is transmitted to the destruction box 3. The transmission device 12 positions the box to the position of the single-phase meter destruction device 4 or the three-phase meter destruction device 5 based on the image recognition information.

[0173] The three-phase meter destroying device 5 and the single-phase meter destroying device 4 both include a lifting device 6 and a destroying assembly 7 , and the destroying assembly 7 includes a plurality of destroying parts. The lifting device 6 is fixedly arranged on the frame of the destroying box 3 .

[0174] In this embodiment, the lifting device 6 is configured as a hydraulic cylinder, which has the characteristics of stable operation and strong driving force.

[0175] Auxiliary guide devices are provided on both sides of the hydraulic cylinder, and the auxiliary guide devices include guide sleeves 61 and guide columns 62 arranged on both sides of the hydraulic cylinder. The guide sleeves 61 are fixedly arranged on the frame, and the guide columns 62 are slidably arranged in the guide sleeves 61. The lower ends of the guide columns 62 are fixedly connected to the destruction assembly 7.

[0176] In this embodiment, the destroying assembly 7 includes a mounting plate 71 . The lifting device 6 drives the mounting plate 71 to move. A plurality of cutting knives 73 are arranged in parallel on the mounting plate 71 .

[0177] The mounting plate 71 is provided with a mounting groove 711 along its width direction, one end of the mounting groove 711 is open, and the upper end of the cutter 73 is provided with a mounting strip 731 that matches the mounting groove 711 .

[0178] In this embodiment, the mounting groove 711 is a mounting groove 711 with a T-shaped cross section, and the mounting strip 731 is a mounting strip 731 with a T-shaped cross section. The cooperation between the mounting strip 731 and the mounting groove 711 makes it more convenient to install and replace the cutter 73.

[0179] A blocking cover 74 is provided at the lower end of the mounting plate 71 , and the blocking cover 74 spans across both sides of the conveying device in the width direction; a plurality of cutting grooves 742 cooperating with the cutting knife 73 are provided through the blocking cover 74 .

[0180] When single-phase meters are placed in the box, 5*7=35 single-phase meters are placed. Therefore, in this embodiment, 5 cutters 73 are set on the mounting plate 71 of the single-phase meter destruction device 4. The 5 cutters 73 are arranged regularly so that when the mounting plate 71 moves downward, each cutter 73 is positioned just to act on the metering sampling module of the single-phase meter, so that the meter is destroyed to prevent it from returning to the market.

[0181] When three-phase meters are placed in the box, 2*5=10 three-phase meters are placed. Therefore, in this embodiment, two cutters 73 are set on the mounting plate 71 of the three-phase meter destruction device 5. The two cutters are arranged regularly so that when the mounting plate 71 moves downward, the position of each cutter 73 just acts on the metering sampling module of the two-phase meter, so that the meter is destroyed to prevent it from returning to the market; at the same time, it can avoid damage to other key parts containing harmful substances such as liquid crystals and electrolytic capacitors to prevent environmental pollution.

[0182] A blocking cover 74 is provided at the lower end of the mounting plate 71 , and the blocking cover 74 spans across both sides of the middle conveying device 12 in the width direction; a plurality of cutting grooves 742 cooperating with the cutting knife 73 are provided through the blocking cover 74 .

[0183] By providing the cutting knife groove 742, when the meter is destroyed, the cutting knife 73 can be prevented from lifting the meter, so that the destroyed meter parts are completely retained in the box.

[0184] In order to make the clamping more stable, the three-phase meter destroying device 5 and the single-phase meter destroying device 4 are both provided with a transverse auxiliary clamping device 8 and a longitudinal auxiliary clamping device 9.

[0185] Reference Figure 5 and Figure 6As shown, the transverse auxiliary clamping device 8 is arranged on the transverse auxiliary clamping device mounting frame 22, and the transverse auxiliary clamping device 8 includes a transverse driving device and two clamping plate assemblies 82; the two clamping plate assemblies 82 are respectively arranged on both sides of the width direction of the conveying device, and the driving device drives the two clamping plate assemblies 82 to move closer to or away from each other.

[0186] The transverse driving device is provided with a driving gear, and the clamping plate assembly 82 includes a transmission rack 824. The transmission racks 824 of the two clamping plate assemblies 82 are meshed on both sides of the driving gear. The transverse driving device is a driving motor 81; the driving motor 81 is fixedly arranged on the transverse auxiliary clamping device mounting frame 22.

[0187] The clamping plate assembly 82 includes a clamping plate base plate 821 , on which a clamping plate strip 822 is arranged. The clamping plate strip 822 is passed through the gap between the electric rollers 121 , and a clamping plate is fixedly arranged on the clamping plate strip 822 , and the clamping plate is parallel to the movement direction of the middle conveying device 12 .

[0188] Two transverse slide rails 83 are arranged in the width direction of the conveying device, and the two transverse slide rails 83 are arranged on the transverse auxiliary clamping device mounting frame 22. Transverse guide blocks 84 cooperating with the transverse slide rails 83 are arranged on both sides of the clamping plate assembly 82.

[0189] Through the cooperation of the transverse guide rail and the transverse guide block 84, the clamping plate assembly 82 is more stable during the movement of moving away and approaching.

[0190] An abutment device 85 is provided on the other side of the transmission rack 824 that is meshed with the transmission gear, and the abutment device 85 abuts against the transmission rack 824 .

[0191] The abutment device 85 can be abutted by an abutment block. In this embodiment, the abutment device 85 includes an abutment column 851 . An abutment bearing 852 is provided on the abutment column 851 . The abutment bearing 852 abuts against the transmission rack 824 .

[0192] The driving motor 81 drives the driving gear to rotate, so that the transmission rack 824 can be driven to move, so that the transmission rack 824 drives the clamping plate assemblies 82 to move closer to or away from each other; therefore, before the meter is damaged, the clamping plate assemblies 82 are controlled to move closer to each other, so that the clamping plates abut against both sides of the box in the width direction, thereby clamping the box, so as to prevent the box from being deformed when the meter is damaged, and to prevent the meter from moving, so as to accurately damage the meter's metering sampling module.

[0193] Reference Figures 8 to 10As shown, the longitudinal auxiliary clamping device 9 includes a fixing plate 93 fixedly arranged at both ends of the length square of the mounting plate 71, the upper edge of the fixing plate 93 is fixedly connected to the mounting plate 71, and a clamping plate 94 is arranged on the fixing plate 93, and the clamping plate 94 is arranged on one side of the facing surface of the two fixing plates 93; the clamping plate 94 can approach or move away from the fixing plate 93; the facing surfaces of the two clamping plates 94 are sequentially provided with a first guide surface 941 and a clamping surface 942 from bottom to top. When the clamping plate 94 is located above the box body, the edges of the two ends of the box body in the length direction correspond to the first guide surface 941 above.

[0194] A piston cavity 932 is provided through the fixed plate 93 near the lower edge. In the present embodiment, three piston cavities 932 are provided. Three fixed columns 943 are provided on the clamping plate 94. The ends of the fixed columns 943 are provided with piston heads 945 that cooperate with the piston cavity 932. A clamping spring 95 is sleeved on the fixed column 943, and the clamping spring 95 abuts between the fixed plate 93 and the clamping plate 94. An oil cavity 933 is provided above the inside of the fixed plate 93, and the oil cavity 933 and the piston cavity 932 are connected through an oil passage 934. Hydraulic oil is provided in the oil cavity 933 and the piston cavity 932, and a vent connected to the oil cavity 933 is provided at the upper end of the fixed plate 93, so that the oil cavity 933 is connected with the outside world, so that the oil pressure in the oil cavity 933 is balanced with the outside world; the side wall of the oil passage 934 is provided with a switch structure for controlling the switch of the oil passage 934.

[0195] The oil passage 934 is vertically arranged in the fixed plate 93, and the switch structure includes an abutment button 96, on which a locking column 961 is arranged; a locking hole 935 is horizontally arranged in the fixed plate 93, and the locking hole 935 is connected to the oil passage 934, and the locking column 961 is slidably arranged in the locking hole 935, and a locking spring 97 is sleeved on the locking column 961, and the locking spring 97 abuts between the fixed plate 93 and the abutment button 96; the abutment button 96 is sequentially provided with a second guide surface 962 and a locking surface 963 from bottom to top; both ends of the blocking cover 74 are provided with locking grooves 743 that cooperate with the fixed plate 93, the lifting device 6 drives the mounting plate 71 to move downward, the cutter 73 destroys the timing of the watch, the locking surface 963 abuts against the side wall of the locking groove 743, and the locking groove 743 pushes the locking column 961 to penetrate into the oil passage 934 to block the oil passage 934.

[0196] The hydraulic cylinder drives the mounting plate 71 to move downward, and the clamping plate 94 gradually abuts against the side wall of the box body. During the abutment process, the piston head on the fixed column 943 slides in the piston cavity 932, so that the hydraulic oil in the piston cavity 932 is pressed back into the oil cavity 933 through the oil passage 934; when the clamping plate 94 is clamped at both ends of the box body, as the cutter 73 continues to descend, the second guide surface 962 and the locking surface 963 on the abutting button 96 abut against the side wall of the locking groove 743 in turn. During the action process, the locking groove 743 pushes the abutting button 96 to move in the direction of the fixed plate 93, so that the locking column 961 crosses the oil passage 934 to block the oil passage 934; The hydraulic oil in the sealed cavity cannot flow back to the oil chamber 933 through the oil passage 934; at this time, the piston head cannot move in the piston chamber 932, so that the abutment plate is in a "hard abutment" state, and because of the initial force of the abutment spring, the abutment plate is tightly fitted to the side wall of the box, so that even if the force exerted by the cutter 73 on the meter is greater, the surface of the box will not be deformed due to the effect of the "hard abutment"; when the meter is cut, the abutment button 96 is disengaged from the abutment groove, and the locking column 961 is pushed away from the oil passage 934 through the force of the locking spring 97, so that the oil passage 934 is re-opened, and then the abutment plate is reset through the force of the abutment spring.

[0197] In Example 4, an abutment plate and a fixing plate 93 are provided to assist in clamping the box body. Although the abutment plate and the fixing plate 93 can clamp the sides of the box body to a certain extent, the clamping force of the abutment plate is provided by the clamping spring 95. Therefore, in the process of destroying the meter, the abutment force of the abutment spring is limited and is in a "soft abutment" state, which will still cause the meter to shift in the box body and cause the surface of the box body to deform. In order to avoid the above situation, this embodiment is provided to solve the above situation.

[0198] Therefore, through the cooperation of the longitudinal auxiliary clamping device 9 and the transverse auxiliary clamping device 8, when the meter is damaged, a clamping effect can be played on all sides of the box, and the box can remain stable, so that the box can be prevented from being deformed when the meter is damaged, and the meter can be prevented from moving, so that the metering sampling module of the meter can be accurately destroyed.

[0199] The working principle of this embodiment is as follows: the box containing the meters is placed on the front conveying device 11, and the front conveying device 11 conveys the box to the identification box 2. The camera mainly performs image recognition and judgment on the whole box of meters to determine whether it is a single-phase meter or a three-phase meter, and whether there are any errors in the number and arrangement of the boxes. When the number in the box is incomplete or the meters in the box are placed in the wrong position, an alarm will be triggered to remind the staff to check the placement of the meters in the box; when there is no error in the number and placement of the meters in the box, it will enter the destruction box 3. The destruction box 3 will be transported to the single-phase meter destruction device 4 or the three-phase meter destruction device according to the image recognition situation by the middle conveying device 12. 5, and then the two sides of the box width direction are clamped by the cooperation of the horizontal auxiliary clamping device 8, and then the hydraulic cylinder drives the mounting plate 71 to move downward, and the cutter 73 passes through the cutter groove 742 to destroy the metering sampling module of the meter. In the process of destroying the meter, the longitudinal auxiliary clamping device 9 clamps the two ends of the box length direction; after the destruction is complete, the hydraulic cylinder drives the mounting plate 71 to move upward, so that the drill bit 72 is pulled out of the meter; then, the longitudinal auxiliary clamping device 9 and the horizontal auxiliary clamping device 8 return to their original positions; then, the damaged electric energy meter in the box is transmitted out through the middle transmission device 12 and the rear transmission device 13. Complete the destruction of the meter. All the controls in this embodiment are completed by PLC control technology, which belongs to the prior art and will not be repeated here; related sensors also belong to the prior art.
