A smart discharge detection device for lead-acid batteries

Abstract

This invention discloses an intelligent discharge detection device for lead-acid batteries, comprising a device body including a chassis. The chassis has heat dissipation mesh holes near the top on its side walls, and air supply sections near the bottom on both sides of the chassis. Each air supply section includes an air inlet shroud, a rotating sleeve, blades, and a fixed beam. The fixed beam is fixedly installed inside the air inlet shroud. Two rotating sleeves are arranged parallel to each other on one side of the fixed beam. In this invention, the blades surrounding the outer circumference of the rotating sleeves are oscillating, with the oscillation direction along the circumferential direction of the rotating sleeves. When the rotating sleeves oscillate back and forth, the blades rotate under inertial force, causing adjacent blades to move in an alternating motion. This motion can tear apart the sludge adhering between adjacent blades. Combined with the centrifugal force generated by the rotation of the rotating sleeves, large volumes of sludge can be thrown off, providing the advantage of reliably cleaning large volumes of hard blockages between the blades without requiring manual cleaning.

Description

Technical Field

[0001] This invention relates to the field of lead-acid battery testing technology, and in particular to an intelligent discharge testing device for lead-acid batteries. Background Technology

[0002] The intelligent discharge testing equipment for lead-acid batteries is used to test the performance of lead-acid batteries. It mainly includes a charge / discharge power unit, a power load unit, and a control unit. The charge / discharge power unit is responsible for providing and controlling the current and voltage during the charging and discharging process. The power load unit is used to simulate the load conditions of the battery in actual use. The main control unit is the core of the entire testing equipment, responsible for controlling and managing all testing processes, including setting test parameters, monitoring test status, recording and analyzing test data.

[0003] Currently, intelligent discharge detection equipment for lead-acid batteries has advantages such as small size, simple operation, and light weight, making it highly portable. However, due to the long operating time and high heat dissipation of this type of intelligent charge / discharge detection equipment, air cooling is necessary. Air cooling is a common and practical method, specifically involving installing multiple cooling fans inside the chassis or on the side wall. To increase air pressure and airflow, these cooling fans typically have a multi-bladed, stacked structure with small spacing between adjacent blades (usually 3-5mm). However, in dusty conditions, this type of cooling fan easily attracts dust and oil between the blades. Over time, a large amount of sludge (a mixture of oil and dust) accumulates on the blades. This dust affects the airflow and air pressure generated by the cooling fan, thus impacting the cooling efficiency of the detection equipment. Furthermore, the structure and installation location of the cooling fan make manual cleaning extremely inconvenient, usually requiring professional personnel to operate the machine for cleaning, increasing labor costs.

[0004] Therefore, this invention proposes an intelligent discharge detection device for lead-acid batteries. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the accumulation of dust on the blades inside the chassis is difficult to clean, which makes it impossible for intelligent testing equipment to reliably and stably test the battery. Therefore, this invention proposes an intelligent discharge testing device for lead-acid batteries.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An intelligent discharge detection device for lead-acid batteries includes a device body, which includes a chassis. The side walls of the chassis have ventilation holes near the top. Air supply sections are located on both sides of the chassis near the bottom. Each air supply section includes an air inlet shroud, rotating sleeves, blades, and a fixed beam. The fixed beam is fixedly installed inside the air inlet shroud. Two rotating sleeves are arranged parallel to each other on one side of the fixed beam. Several blades surround the outer periphery of each rotating sleeve. A connecting plate is fixed to one side of each blade and connects to the rotating sleeve in a swinging manner. When the connecting plate swings to its limit, a clean structure is formed. In the air supply structure state and the cleaning structure state, the opposite sides of the adjacent blades are approximately in contact. In the air supply structure state, the vertical line passing through the blade and the axis of the rotating sleeve may intersect but not coincide, and the distance between the adjacent blades increases. The air supply part includes a U-shaped cleaning frame located between two rotating sleeves. There are two U-shaped cleaning frames, which are respectively set close to the two rotating sleeves. The opening of the U-shaped cleaning frame faces the adjacent blade and slides with the fixed beam. Brushes are provided on the opposite sides of the U-shaped cleaning frame. The fixed beam is provided with a control mechanism for controlling the synchronous but opposite movement of the two U-shaped cleaning frames.

[0008] As a further description of the above technical solution:

[0009] Two wedge-shaped blocks with their large ends facing the rotating sleeve are fixedly connected to one side of the fixed beam. A slider is provided on the inclined surface of the front side of the wedge-shaped block. The front side of the slider is fixedly connected to one side of the U-shaped cleaning frame through a connecting rod.

[0010] As a further description of the above technical solution:

[0011] The control mechanism includes a transmission plate, a gear, and an electric push rod. The gear is rotatably mounted on the other side of the fixed beam. There are two transmission plates, located on the upper and lower sides of the gear, respectively. The transmission plates mesh with the gear and are slidably connected to the fixed beam. A U-shaped lever is welded to one side of the transmission plate. A lever shaft located inside the U-shaped lever is fixedly connected to one side of the slider. The electric push rod is fixedly mounted on one side of the fixed beam, and its output shaft is fixedly connected to one end of one of the transmission plates.

[0012] As a further description of the above technical solution:

[0013] The rotating sleeve contains a permanent magnet frustum that magnetically engages with the blade plate. A drive shaft is fixedly connected to one side of the permanent magnet frustum. An L-shaped plate that slides with the drive shaft is fixedly connected to the other side of the fixed beam. Slide plates located on the left and right sides of the gear are provided on the other side of the fixed beam. One side of each of the two drive plates is fixedly connected to one side of the adjacent slide plate via an adapter plate. One side of the L-shaped rod is connected to the other side of the fixed beam via a tension spring. A roller is connected to the outer wall of the drive shaft via the L-shaped rod. The side of the slide plate facing away from the fixed beam is opposite to the roller and has a slope at one end.

[0014] As a further description of the above technical solution:

[0015] The outer peripheral wall of the rotating sleeve is provided with clearance slots that correspond one-to-one with the blades. One end of the blade is fixedly connected to a magnetic block that can enter and exit the clearance slots and magnetically engage with the outer peripheral wall of the permanent magnet frustum.

[0016] As a further description of the above technical solution:

[0017] One end of the rotating sleeve is fixedly connected to a transmission pipe, and a positioning sleeve fitted outside the transmission pipe is fixedly connected to the fixed beam. The transmission pipe is connected to the positioning sleeve through a bearing.

[0018] As a further description of the above technical solution:

[0019] The outer peripheral wall of the rotating sleeve is fixedly connected to a connecting lug plate. A positioning hole is provided on one side of the connecting lug plate. A connecting shaft that is rotatably connected to the positioning hole is welded to one side of the connecting plate. The connecting shaft and the positioning hole are transitionally fitted.

[0020] As a further description of the above technical solution:

[0021] The opening end face of the air inlet cover is fixedly connected to the outer side wall of the chassis. A window communicating with the air inlet cover is provided on the side wall of the chassis. A protective net opposite to the rotating sleeve is provided on the side of the air inlet cover away from the chassis. A conical dust leakage box is fixedly connected to the bottom of the air inlet cover. The bottom opening of the conical dust leakage box is provided.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, the blades surrounding the outer circumference of the rotating sleeve are configured as a swingable structure. The swing direction of the blades is along the circumferential direction of the rotating sleeve. When the rotating sleeve swings back and forth, the blades will rotate under the action of inertial force. Adjacent blades will generate interlaced motion. This motion can tear apart the sludge adhering between adjacent blades. Combined with the centrifugal force generated by the rotation of the rotating sleeve, it can throw away large volumes of sludge. It has the advantage of reliably cleaning large volumes of hard blockages between blades without the need for manual cleaning.

[0024] 2. In this invention, two slidable U-shaped cleaning frames are set between two rotating sleeves. When the rotating sleeves rotate in both directions, the blades distributed around their outer periphery will swing and transform into two states: one is the air supply structure state, and the other is the cleaning structure state. In the cleaning structure state, when the U-shaped cleaning frame moves towards the blade and moves to the set position, the brush strips inside the U-shaped cleaning frame can evenly contact both sides of the blade, so that the dirt remaining on the blade can be thoroughly cleaned, which can effectively prevent the dirt between the blades from accumulating rapidly.

[0025] 3. In this invention, the rotating sleeve contains a permanent magnet frustum for applying magnetic attraction to the blade. The permanent magnet frustum can move axially. When it moves axially away from the blade, the blade will not be magnetically attracted. At this time, the blade can swing freely relative to the rotating sleeve. When the blade is magnetically attracted, the blade can rotate synchronously with the rotating sleeve. Thus, when the blade is in the air supply structure state, the blade will be reliably attracted by the permanent magnet frustum, so that the blade can be firmly followed by the rotating sleeve to rotate without generating vibration noise.

[0026] 4. In this invention, a transmission plate, gears, electric push rods, transmission shafts, sliders, and L-shaped rods are provided, enabling the U-shaped cleaning frame and the permanent magnet truncated cone to have a linkage function. This arrangement simplifies the structure of the air supply section, reduces the space occupied by the air supply section, and does not affect the portability of this testing equipment.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figure 1-9An intelligent discharge testing device for lead-acid batteries includes a main body, which includes a chassis 1. The chassis 1 houses a charge / discharge power unit, a power load unit, and an intelligent main control unit. These components are typically integrated onto a circuit board mounted within the chassis 1. The power conversion module and power devices on the charge / discharge power unit, as well as the power resistors on the power load unit, are the main heat-generating components, requiring air cooling during operation. A human-machine interface module is located on one side of the chassis 1. This module is electrically connected to the intelligent main control unit. The human-machine interface module includes a touchscreen, knobs, indicator lights, wiring ports, and switches. There are at least two sets of wiring ports. During use, the wiring ports are plugged into the testing leads, and the testing leads are connected to the two terminals on the lead-acid battery (e.g., using clips). The lead-acid battery can then be tested.

[0041] When the testing equipment is started, it needs to be cooled. The side wall of the chassis 1 is provided with heat dissipation mesh 2 near the top. The heat dissipation mesh 2 is the channel for the high temperature air inside the chassis 1 to be discharged. The sides of the chassis 1 are provided with air supply parts 3 near the bottom. The function of the air supply parts 3 is to send fresh air into the chassis 1. The number of air supply parts 3 depends on the heat dissipation requirements.

[0042] Specifically, the air supply unit 3 includes an air inlet shroud 31, a rotating sleeve 32, a blade 33, and a fixed beam 34. The air inlet shroud 31 is a square box structure with one side open. The open end face of the air inlet shroud 31 is fixedly connected to the outer side wall of the casing 1, specifically by screw fastening. The side wall of the casing 1 has a window communicating with the air inlet shroud 31. The fixed beam 34 is fixedly installed inside the air inlet shroud 31. Specifically, both ends of the fixed beam 34 are fixedly connected to the two side walls inside the air inlet shroud 31, respectively. There are two rotating sleeves 32, which are arranged parallel to each other on one side of the fixed beam 34. In specific implementation, one end of the rotating sleeve 32 is fixedly connected to a transmission pipe 321. A positioning sleeve 344 is fixedly connected to the fixed beam 34 and sleeved outside the transmission pipe 321. The transmission pipe 321 is connected to the positioning sleeve 344 through a bearing. When the transmission pipe 321 rotates in both directions, it can drive the rotating sleeve 32 to rotate in both directions. The outer periphery of the rotating sleeve 32 is surrounded by several blades 33. A connecting plate 331, which is oscillatingly connected to the rotating sleeve 32, is fixed to one side of each blade 33. The connecting plate 331 and the blades 33 are not coplanar, and the included angle between them is between 165 and 170 degrees. In specific implementation, a connecting lug 323 is fixedly connected to the outer peripheral wall of the rotating sleeve 32. A positioning hole 3231 is opened on one side of the connecting lug 323. A connecting shaft 3311, which rotatably connects to the positioning hole 3231, is welded to one side of the connecting plate 331. The connecting shaft 3311 and the positioning hole 3231 are in a transition fit. When the rotating sleeve 32 rotates back and forth, the blades 33 will oscillate back and forth relative to the circumference of the rotating sleeve 32 due to their own inertial force. At this time, adjacent blades 33 move and misalign, tearing the sludge adhering between adjacent blades. When the connecting plate 331 oscillates to its limit, it will correspondingly form a clean structure state and an air supply structure state. The switching between these two states can be achieved by controlling the forward and reverse rotation of the rotating sleeve 32. In the air supply structure state, the vertical line passing through the blade 33 and the axis of the rotating sleeve 32 can intersect but not coincide, and the distance between adjacent blades 33 increases. In this state, when the rotating sleeve 32 is controlled to rotate at high speed, the uniformly distributed blades 33 will generate airflow that flows at high speed into the casing 1. A protective net 311 is provided on the side of the air inlet cover 31 that is opposite to the rotating sleeve 32. The protective net 311 is also directly opposite the blade 33. The protective net 311 is used to filter large debris such as weeds and leaves. The filtered air enters the casing 1.

[0043] In the clean structure state, the adjacent blades 33 are approximately in contact. When the rotating sleeve 32 rotates at high speed, the air volume generated by the blades 33 is greatly reduced, and the transition (step state) of the plate surfaces on both sides of the adjacent blades 33 is smoother.

[0044] Furthermore, the air supply unit 3 includes a U-shaped cleaning frame 35 located between two rotating sleeves 32. There are two U-shaped cleaning frames 35, which are respectively located close to the two rotating sleeves 32. The opening of the U-shaped cleaning frame 35 faces the adjacent blade 33 and is slidably engaged with the fixed beam 34. In a specific implementation, two wedge-shaped blocks 341 with their large ends facing the rotating sleeves 32 are fixedly connected to one side of the fixed beam 34. A slider 3411 is provided on the inclined surface of the front side of the wedge-shaped block 341. When the slider 3411 moves, it slides along the inclined surface. The front side of the slider 3411 is fixedly connected to one side of the U-shaped cleaning frame 35 through a connecting rod 34111. When the slider 3411 moves, it can drive the U-shaped cleaning frame 35 to move along the inclined surface of the front side of the wedge-shaped block 341. In the cleaning structure state, when the U-shaped sweeping frame 35 moves towards the adjacent blade 33, one of the blades 33 will enter the U-shaped groove of the U-shaped sweeping frame 35 at the same time. Brushes 351 are provided on opposite sides inside the U-shaped sweeping frame 35. When making the wedge block 341, the inclination angle of the inclined surface of the wedge block 341 is determined according to the inclination angle of the blade 33 relative to the axis of the rotating sleeve 32 in the cleaning structure state, ensuring that the two side walls of the blade 33 passing through the U-shaped sweeping frame 35 are evenly squeezed by the brushes 351. When the rotating sleeve 32 rotates at high speed, the two side walls of the blade 33 will be scraped and cleaned by the brushes 351, thereby cleaning away the residual dust on both sides of the blade 33. It should be noted that in the cleaning structure state, the blade 33 will not cut and damage the brushes 351.

[0045] The fixed beam 34 is equipped with a control mechanism 4 for controlling the synchronous, opposite-direction movement of the two U-shaped cleaning frames 35. Specifically, the two U-shaped cleaning frames 35 simultaneously move closer to and further away from their respective adjacent blades. In the cleaning structure state, when the two U-shaped cleaning frames 35 are controlled to move in opposite directions to a preset position, the two U-shaped cleaning frames 35 will respectively engage with the outside of the adjacent blades 33. When the U-shaped cleaning frames 35 are controlled to detach from the blades 33, the blades 33 are in the air supply structure state, so the U-shaped cleaning frames 35 will not interfere with the operation of the blades 33.

[0046] Specifically, the control mechanism 4 includes a transmission plate 41, a gear 42, and an electric push rod 43. The gear 42 is rotatably mounted on the other side of the fixed beam 34. In a specific implementation, a support sleeve is fixedly installed in the middle of the other side of the fixed beam 34. The gear 42 is fitted inside the support sleeve and the two are rotatably connected. There are two transmission plates 41, which are located on the upper and lower sides of the gear 42, respectively. The transmission plates 41 and the gear 42 mesh and are slidably connected to the fixed beam 34. In a specific implementation, a groove is opened on one side of the transmission plate 41. Slide rails passing through the groove are fixedly installed on the upper and lower sides of the fixed beam 34. A rack that meshes with the gear 42 is fixedly connected to one side of the transmission plate 41. Under the transmission restriction of the gear 42, the two transmission plates 41 move in different directions. A U-shaped lever plate 411 is welded to one side of the transmission plate 41, and a lever shaft 34112 located inside the U-shaped lever plate 411 is fixedly connected to one side of the slider 3411. When the transmission plate 41 moves, it pushes the lever shaft 34112 through the U-shaped lever plate 411, which in turn pushes the slider 3411 to move. An electric push rod 43 is fixedly installed on one side of the fixed beam 34, and its output shaft is fixedly connected to one end of one of the transmission plates 41. The electric push rod 43 provides a driving force for the movement of one of the transmission plates 41.

[0047] In this embodiment, the rotating sleeve 32 contains a permanent magnet frustum 5 that magnetically engages with the blade 33. The function of the permanent magnet frustum 5 is to magnetically attract the blade 33. When the blade 33 is in the air supply structure state, the blade 33 can reliably press against the outer circular wall of the rotating sleeve 32 when the permanent magnet frustum 5 magnetically attracts the blade 33. There is a gap between the permanent magnet frustum 5 and the rotating sleeve 32. A drive shaft 51 is fixedly connected to one side of the permanent magnet frustum 5, and an L-shaped plate 342 that slides with the drive shaft 51 is fixedly connected to the other side of the fixed beam 34. In specific implementation, a limiting sleeve can be fixedly installed on a straight plate on the L-shaped plate 342 and sleeved outside the drive shaft 51. The limiting sleeve and the drive shaft 51 slide axially. When the drive shaft 51 slides axially, it can drive the permanent magnet frustum 5 to move axially within the rotating sleeve 32. When the permanent magnet frustum 5 is offset from the blade 33, the magnetic attraction force on the blade 33 is reduced or even disappears. When the magnetic attraction force disappears, the blade 33 can swing freely in the circumferential direction relative to the rotating sleeve 32.

[0048] Furthermore, on the other side of the fixed beam 34, there are sliding plates 343 located on the left and right sides of the gear 42. The sliding plates 343 and the fixed beam 34 are laterally slidably connected. One side of each of the two transmission plates 41 is fixedly connected to one side of the adjacent sliding plate 343 through a transition plate 412. When the transmission plates 41 move, they can synchronously drive the sliding plates 343 to move. The outer wall of the transmission shaft 51 is connected to a roller 5111 through an L-shaped rod 511. One side of the L-shaped rod 511 is connected to the other side of the fixed beam 34 through a tension spring 6. Specifically, the tension spring 6... Both ends are fixedly connected to the L-shaped rod 511 and the fixed beam 34 respectively. The side of the slide plate 343 facing away from the fixed beam 34 is opposite to the roller 5111 and has a slope 3431 at one end. Under the elastic tension of the tension spring 6, the roller 5111 will press against the side wall of the slide plate 343 facing away from the fixed beam 34. When the roller 5111 rolls into the slope 3431, the drive shaft 51 will move axially, which can drive the permanent magnet frustum 5 to move axially, thereby controlling the distance between the permanent magnet frustum 5 and the blade 33. In order to enable the magnetic attraction force generated by the permanent magnet frustum 5 to effectively attract the blade 33, during manufacturing, a clearance groove 324 corresponding to the blade 33 can be opened on the outer peripheral wall of the rotating sleeve 32. One end of the blade 33 is fixedly connected to a magnetic block 332 that can enter and exit the clearance groove 324 and magnetically engage with the outer peripheral wall of the permanent magnet frustum 5. The clearance groove 324 is designed to reduce the distance between the magnetic block 332 and the permanent magnet frustum 5.

[0049] In this embodiment, a conical dust collection box 312 is fixedly connected to the bottom of the air inlet cover 31. The conical dust collection box 312 is used to collect large particles of sludge. The bottom of the conical dust collection box 312 is open, and the sludge in the conical dust collection box 312 is discharged through the bottom opening by its own weight. It should be noted that the two sides of the casing 1 are connected to the cover by bolts. After the cover is removed, the dust on the circuit board can be blown away with an air gun, making it more convenient to clean the dust on the circuit board.

[0050] In this embodiment, a servo motor is fixedly installed in the middle of the fixed beam 34. The output shaft of the servo motor is connected to the transmission tube 321 on one of the rotating sleeves 32 through the first belt drive group. The transmission tubes 321 on the two rotating sleeves 32 are connected through the second belt drive group. When the servo motor rotates forward and backward, the two rotating sleeves 32 will rotate forward and backward synchronously. A controller (PLC) is fixedly installed on the inner wall of the air inlet cover 31. The controller is electrically connected to the aforementioned servo motor and electric push rod 43. Then, an operation panel is installed on the outer wall of the air inlet cover 31. The operation panel is electrically connected to the controller (PLC). A knob or button is provided on the operation panel. The cleaning mode can be started by turning the knob or button.

[0051] Working principle: When the user observes excessive sludge between the blades 33 through the protective net 311, the cleaning mode is manually activated. The controller starts the servo motor to rotate forward and backward for 10 minutes, with a switching cycle of 1 minute between forward and reverse rotation. During reverse rotation, the evenly distributed blades 33 are in a clean structure state, while during forward rotation, the evenly distributed blades 33 are in an air supply state. When switching between the clean structure state and the air supply state, the sludge adhering between adjacent blades 33 is pulled apart. During this process, the large volume of sludge torn apart between the blades 33 is centrifugally thrown away. When the servo motor reverses, the controller simultaneously controls the electric push rod 43 to move one of the transmission plates 41. Under the transmission of the gear 42, the two transmission plates 41 move in opposite directions. The U-shaped baffle 411 can push the baffle shaft 34112 to move. The baffle shaft 34112 will push the slider 3411 to move along the wedge block 341, thereby driving the U-shaped sweeping frame 35 to move. The revolving blade 33 will pass through the inner groove of the U-shaped sweeping frame 35. The brush 351 scrapes and cleans the front and rear sides of the blade 33, which can effectively scrape away the remaining small particles of sludge. When the two transmission plates 41 move in opposite directions, the slide plate 343 is driven to move by the adapter plate 412. The roller 5111 rolls along the slope 3431 and goes uphill. At this time, the L-shaped rod 511 drives the transmission shaft 51 to slide along the L-shaped plate 342. The permanent magnet truncated cone 5 is driven to move and move away from the magnetic block 332. The magnetic force on the magnetic block 332 decreases. The blade 33 will swing to the position where the connecting plate 331 and the outer circular wall of the rotating sleeve 32 meet by inertial force. This position is the cleaning structure state position. When the servo motor rotates forward and triggers, the controller simultaneously controls the electric push rod 43 to reset. The U-shaped cleaning frame 35 leaves the blade 33. Through the above operations, the dirt on the blade 33 can be cleaned and the air supply capacity of the air supply unit 3 can be restored.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
