[0004] The utility model aims to solve the shortcomings in the prior art and proposes an electrical component maintenance device for a sewage treatment tank.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electrical component maintenance device for a sewage treatment tank, comprising an electrical box, a circuit breaker is fixed to the inner wall of the electrical box, a switch is provided on the front of the circuit breaker, a maintenance module is fixed to the front of the circuit breaker, an arc groove is opened on one side of the maintenance module, a mounting groove is fixed to the inner wall of the maintenance module, a fixing plate is fixed to the inner wall of the mounting groove, a two-way part is rotatably connected to the back of the fixing plate, the two-way part is driven by a reversible motor, a lever is fixed to one side of the two-way part, a limit rod is fixed to the front of the fixing plate, a main shaft is fixed to the front of the fixing plate, a force-bearing rod is rotatably connected to the circumference of the main shaft, a swing frame is fixed to the bottom of the force-bearing rod, and the inner wall of the swing frame is fixed There is a pressure rod, an arc track is fixed at the bottom of the fixed plate, a swing head is slidably connected to the surface of the arc track, a moving rod is fixed to the top of the swing head, a force storage spring is arranged on the circumference of the moving rod, a slide groove is opened on the surface of the moving rod, the inner wall of the slide groove is slidably connected to the surface of the pressure rod, a short arc rod is fixed on one side of the swing head, the surface of the short arc rod is slidably connected to the inner wall of the arc groove, an outer connecting rod is fixed at one end of the short arc rod, and a switch is arranged on the surface of the outer connecting rod. In the prior art, in the electrical components of the sewage treatment tank, the circuit breaker plays a key role in protecting the safety of circuits and equipment. In the sewage treatment system, the circuit breaker plays a core role in protecting the safety of electrical equipment and circuits. Especially when overhauling key equipment such as pumps or fans, staff often need to quickly switch on and off multiple times. This operation can effectively avoid the problem of line burning caused by the failure of the equipment to rotate. However, in actual working scenarios, some circuit breakers are installed far away from the pump or fan, which makes it difficult for the staff to effectively observe the operating status of the equipment while performing the opening and closing operations. This situation not only reduces the efficiency of the maintenance work, but also increases the risk of equipment damage. In view of such problems, the utility model solves the problem by installing a maintenance module, so that when the staff arrives at the pump or fan and needs to remotely open and close the circuit breaker multiple times and quickly, the staff starts the reversible motor to drive the two-way part to rotate clockwise, pushes the force-bearing rod to rotate clockwise, and the pressure rod of the swing frame is When the movable rod is pushed to rotate counterclockwise, the pressure rod is sent into the slide groove of the movable rod gradually. When the pressure rod penetrates into the slide groove, the storage spring is compressed to accumulate elastic potential energy. When the pressure rod rotates clockwise to one side of the fixed plate, the swing head slides on the arc track to change the direction of the force, the contact area suddenly decreases and the friction force is reduced. The storage spring quickly releases the elastic potential energy, pushing the swing head to move quickly along the arc track to the other side. At the same time, the short arc rod and the outer connecting rod switch knife move to energize it. Subsequently, the reversible motor reverses to drive the two-way part to rotate counterclockwise. Repeating the above steps allows the staff to remotely and quickly open and close the circuit breaker multiple times at a distance from the pump or fan, which is convenient for the staff to control, thereby improving the user experience, increasing work efficiency, and improving the safety of equipment use.

[0006] Preferably, a large arc fastener is fixed to the circumferential surface of the outer connecting rod, and the inner wall of the large arc fastener is nested with the surface of the knife. In the prior art, if the outer connecting rod and the knife are fixed, the later disassembly is relatively complicated, and the knife is a part of the circuit breaker of the electrical component. If non-professionals fix it, it is easy to cause damage to the equipment. At the same time, the outer connecting rod and the knife are both cylindrical, and the contact surface between the two is small, and the fixing point is easy to detach, resulting in production accidents. To solve such problems, the utility model adopts the method of installing large arc fasteners to achieve a solution, which realizes that when the knife is embedded in the large arc fastener, the contact area between the two is greatly increased, which greatly improves the stability and firmness of the contact. Due to the increase in contact area, the friction between the large arc fastener and the knife is significantly enhanced, thereby reducing the fastener during use. The risk of falling off during the operation not only ensures the stability of the components during the operation of the machine, but also provides a mechanism for quick loading and unloading, which is convenient for the staff to operate and maintain. The increased contact area also promotes the synchronous movement effect of the large arc fastener and the knife, which means that during the operation of the machine, the two can work together more harmoniously to reduce mechanical wear or failure caused by improper cooperation. The optimization of synchronous movement not only improves the mechanical efficiency, but also extends the service life of the equipment. At the same time, this design also takes into account the convenience of actual operation. Even if the contact area and stability are increased, the large arc fastener can still be quickly disassembled through simple operation, which provides great convenience for the staff to carry out equipment maintenance, overhaul or replacement of parts, thereby improving work efficiency.

[0007] Preferably, a diagonal tie rod is fixed to the circumferential surface of the outer connecting rod, and one end of the diagonal tie rod is fixed to one end of the short arc rod. In the prior art, since the force-generating position of the short arc rod is far away from the distal end of the knife, the outer connecting rod is easily deformed, resulting in a large force at the proximal end of the outer connecting rod and a small force at the distal end, causing the outer connecting rod to break, thereby reducing the service life of the equipment. To solve this problem, the utility model adopts the method of installing diagonal tie rods to achieve a stable triangular structure formed by the diagonal tie rods, the diagonal tie rods, the outer connecting rod and the short arc rod, so that the distal end of the knife is also subjected to force at the same time, ensuring force uniformity, preventing components from deformation or breakage, and achieving the effect of increasing the service life of the equipment.

[0008] Preferably, a limit plate is fixed on the top of the swing head to prevent the force storage spring from exceeding its limit compression length due to compression interference, causing permanent deformation of the force storage spring and improving the service life of the equipment.

[0009] Preferably, a rubber pad is adhesively connected to the top of the limit plate to provide a buffer space to prevent the top of the limit plate from colliding and scratching with the bottom of the hem frame, protect the surface layer of the component, prevent rust caused by damage to the surface layer, and increase the service life of the equipment.

[0010] Preferably, the central angle between the two ends of the short arc rod is less than 5 degrees, so as to prevent scratching and improve work efficiency.

[0011] Preferably, the angle between the outer connecting rod and the inclined rod is smaller than the angle between the center angles of the two ends of the short arc rod, thereby improving the adaptability of the components.

[0012] Beneficial effects:

[0013] 1. In the prior art, among the electrical components of the sewage treatment tank, the circuit breaker plays a key role in protecting the safety of the circuit and equipment. In the sewage treatment system, the circuit breaker plays a core role in protecting the safety of electrical equipment and circuits. Especially when inspecting and repairing key equipment such as pumps or fans, the staff often need to quickly open and close the circuit breaker many times, and observe whether these equipment can rotate normally. This operation can effectively avoid the problem of line burning caused by the inability of the equipment to rotate. However, in actual working scenarios, some circuit breakers are installed far away from the pump or fan, which makes it difficult for the staff to effectively observe the operating status of the equipment while performing the opening and closing operations. This situation not only reduces the efficiency of the maintenance work, but also increases the risk of equipment damage. In response to such problems, the utility model adopts the method of installing an inspection module to solve the problem, so that when the staff arrives at the pump or fan, they need to remotely observe the operation status of the equipment. When the circuit breaker is opened and closed quickly many times, the staff starts the reversible motor to drive the two-way part to rotate clockwise, pushing the force-bearing rod to rotate clockwise. While the pressure rod of the lower swing frame drives the moving rod to rotate counterclockwise, the pressure rod is sent into the slide groove which gradually enters the moving rod. While the pressure rod penetrates into the slide groove, the force storage spring is compressed to accumulate elastic potential energy. When the pressure rod rotates clockwise to one side of the fixed plate, the swing head slides on the arc track to change the direction of the force, the contact area suddenly decreases and the friction force is reduced. The force storage spring quickly releases the elastic potential energy and pushes the swing head to move quickly along the arc track to the other side. At the same time, the short arc rod and the outer connecting rod switch knife move to energize it. Subsequently, the reversible motor reverses to drive the two-way part to rotate counterclockwise. The above steps are repeated, so that the staff can remotely and quickly open and close the circuit breaker many times at a distance from the pump or fan, which is convenient for the staff to control, so as to improve the user experience, increase the work efficiency, and improve the safety of equipment use.

[0014] 2. In the prior art, if the outer connecting rod and the knife are fixed, the later disassembly is more complicated, and the knife is part of the circuit breaker of the electrical component. If non-professionals fix it, it is easy to cause damage to the equipment. At the same time, the outer connecting rod and the knife are both cylindrical, and the contact surface between the two is small. The fixing part is easy to detach, resulting in production accidents. In view of such problems, the utility model adopts the method of installing a large arc fastener to solve them. When the knife is embedded in the large arc fastener, the contact area between the two is greatly increased, which greatly improves the stability and firmness of the contact. Due to the increase in the contact area, the friction between the large arc fastener and the knife is significantly enhanced, thereby reducing the risk of the fastener falling off during use, which not only ensures that the machine The stability of the components during operation also provides a mechanism for quick loading and unloading, which is convenient for staff to operate and maintain. The increased contact area also promotes the synchronous movement of the large arc fastener and the knife, which means that during the operation of the machine, the two can work together more harmoniously to reduce mechanical wear or failure caused by improper cooperation. The optimization of synchronous movement not only improves the mechanical efficiency, but also extends the service life of the equipment. At the same time, this design also takes into account the convenience of actual operation. Even if the contact area and stability are increased, the large arc fastener can still be quickly disassembled through simple operation, which provides great convenience for staff to carry out equipment maintenance, overhaul or replacement of parts, thereby improving work efficiency.

[0015] 3. In the prior art, since the force-generating position of the short arc rod is far away from the distal end of the knife, it is easy to cause the outer connecting rod to deform, resulting in a large force at the proximal end of the outer connecting rod and a small force at the distal end, causing the outer connecting rod to break, thereby reducing the service life of the equipment. To address this problem, the utility model solves it by installing an inclined tie rod, which realizes a stable triangular structure formed by the inclined tie rod, the outer connecting rod and the short arc rod, so that the distal end of the knife is also stressed at the same time, ensuring uniform force, preventing deformation or breakage of components, and achieving the effect of increasing the service life of the equipment.

In the electrical components of the sewage treatment tank, the circuit breaker starts In the sewage treatment system, circuit breakers play a key role in protecting the safety of electrical equipment and circuits. Especially when inspecting key equipment such as pumps or fans, workers often need to quickly open and close circuit breakers many times and observe whether these equipment can rotate normally. This operation can effectively avoid the problem of line burning caused by the inability of equipment to rotate. However, in actual working scenarios, some circuit breakers are installed far away from pumps or fans, which makes it difficult for workers to effectively observe the operating status of the equipment while performing opening and closing operations. This situation not only reduces the efficiency of maintenance work, but also increases the risk of equipment damage. The installation of maintenance module 2 solves this problem and achieves When the staff arrives at the pump or fan and needs to remotely open and close the circuit breaker 101 multiple times and quickly, the staff starts the reversible motor 205 to drive the two-way member 204 to rotate clockwise, pushing the force-bearing rod 208 to rotate clockwise. At the same time, the pressure rod 2011 of the lower swing frame 2010 drives the movable rod 2015 to rotate counterclockwise, and the pressure rod 2011 is sent into the slide groove 2016 that gradually enters the movable rod 2015. When the pressure rod 2011 penetrates into the slide groove 216, it compresses the force storage spring 217 to accumulate elastic potential energy. When the pressure rod 2011 rotates clockwise to one side of the fixed plate 203, the swing head 2013 slides on the arc track 2012 to change the direction of the force, the contact area is suddenly reduced, and the friction force is reduced. The force storage spring 2017 quickly releases the elastic potential energy.Push the swing head 2013 to quickly move along the arc track 2012 to the other side, and at the same time, the short arc rod 2018 and the outer connecting rod 2019 switch 102 move to energize it. Then, the reversible motor 205 reverses and drives the two-way member 204 to rotate counterclockwise. Repeat the above steps, so that the staff can remotely and quickly open and close the circuit breaker 101 multiple times at a distance from the pump or fan, which is convenient for the staff to control, thereby improving the user experience, increasing work efficiency, and improving the safety of equipment use. A limit plate 2014 is fixed on the top of the swing head 2013 to prevent the compression interference from exceeding the limit compression length of the force storage spring 2017, causing permanent deformation of the force storage spring 2017, and improving the service life of the equipment. A rubber pad is glued to the top of the limit plate 2014 to provide a buffer space to prevent the top of the limit plate 2014 from colliding and scratching with the bottom of the lower swing frame 2010, protect the surface layer of the component, and prevent rust caused by damage to the surface layer, thereby improving the service life of the equipment.

[0028] A large arc fastener 2020 is fixed to the circumference of the outer connecting rod 2019, and the inner wall of the large arc fastener 2020 is nested with the surface of the knife 102. If the outer connecting rod 2019 and the knife 102 are fixed, the later disassembly is more complicated, and the knife 102 is a part of the electrical component circuit breaker 101. If non-professionals fix it, it is easy to cause damage to the equipment. At the same time, the outer connecting rod 2019 and the knife 102 are both cylindrical, and the contact surface between the two is small. The fixing part is easy to detach, resulting in production accidents. The problem is solved by installing a large arc fastener 2020. When the knife 102 is embedded in the large arc fastener 2020, the contact area between the two is greatly increased, which greatly improves the stability and firmness of the contact. Due to the increase in contact area, the friction between the large arc fastener 2020 and the knife 102 is significantly enhanced, thereby reducing The risk of fasteners falling off during use is reduced, which not only ensures the stability of components during mechanical operation, but also provides a mechanism for quick loading and unloading, which is convenient for staff to operate and maintain. The increased contact area also promotes the synchronous movement effect of the large arc fastener 2020 and the knife 102, which means that during the operation of the machine, the two can work together more harmoniously to reduce mechanical wear or failure caused by improper cooperation. The optimization of synchronous movement not only improves mechanical efficiency, but also extends the service life of the equipment. At the same time, this design also takes into account the convenience of actual operation. Even if the contact area and stability are increased, the large arc fastener 2020 can still be quickly disassembled through simple operation, which provides great convenience for staff to carry out equipment maintenance, overhaul or replacement of parts, thereby achieving the effect of improving work efficiency. The outer connecting rod 2019 is fixed with an inclined tie rod 2021 on the circumference of the surface, and one end of the inclined tie rod 2021 is fixed to one end of the short arc rod 2018. Since the force position of the short arc rod 2018 is far from the far end of the gate knife 102, it is easy to cause the outer connecting rod 2019 to deform, resulting in a large force at the near end of the outer connecting rod 2019, while the force at the far end is small, causing the outer connecting rod 2019 to break, reducing the service life of the equipment. The inclined tie rod 2021 is installed to solve the problem, so that the inclined tie rod 2021, the outer connecting rod 2019 and the short arc rod 2018 form a stable triangular structure through the inclined tie rod 2021, so that the far end of the gate knife 102 is also stressed at the same time, ensuring uniform force, preventing deformation or breakage of the components, and achieving the effect of increasing the service life of the equipment. The central angle of the two ends of the short arc rod 2018 is less than 5 degrees, which prevents scratches and improves work efficiency. The angle between the outer connecting rod 2019 and the inclined rod 2021 is smaller than the central angle of the two ends of the short arc rod 2018, thereby improving the adaptability of the components.

[0029] Working principle of the utility model: when the staff arrives at the pump or fan and needs to remotely open and close the circuit breaker 101 multiple times and quickly, the staff starts the reversible motor 205 to drive the two-way member 204 to rotate clockwise to push the force-bearing rod 208 to rotate clockwise, and the pressure rod 2011 of the lower swing frame 2010 drives the moving rod 2015 to rotate counterclockwise, while the pressure rod 2011 is sent into the slide groove 216 that gradually enters the moving rod 2015, and the pressure rod 2011 penetrates into the slide groove 216 while compressing the storage spring 217 to accumulate elastic potential energy. When the pressure rod 2011 rotates clockwise When it turns to one side of the fixed plate 203, the swing head 2013 slides on the arc track 2012 to change the direction of the force, the contact area suddenly decreases, the friction force is reduced, and the force storage spring 2017 quickly releases the elastic potential energy, pushing the swing head 2013 to move quickly along the arc track 2012 to the other side. At the same time, the short arc rod 2018 and the outer connecting rod 2019 switch 102 move to energize it. Subsequently, the reversible motor 205 reverses and drives the two-way part 204 to rotate counterclockwise. Repeating the above steps allows the staff to remotely and quickly open and close the circuit breaker 101 multiple times at a distance from the pump or fan.
