Description

Technical Field

[0001] The present invention relates to the technical field of battery maintenance, and specifically to a maintenance conduit assembly. Background Art

[0002] After a battery has been used for a long time, lead sulfide is extruded at both ends of the positive and negative electrodes of the battery. This part of the battery is severely sulfided, resulting in a decrease in energy storage. By inserting a conduit into the battery to blow bubbles, the liquid inside the battery is homogenized, and the extruded lead sulfide is homogenized to ensure the energy storage performance of the battery;

[0003] In the existing maintenance conduit assemblies, there is a lack of convenient and effective clamping components, which cannot ensure the stability of the battery body during the actual injection process, making it inconvenient to load and unload the battery. Moreover, due to different battery specifications, the positions of the repair ports of the batteries are different. Therefore, flexible displacement control is required. During the injection of the homogenizing reagent, a large amount of air is easily injected into the battery, and the dust in the air will contaminate the battery. For this reason, we propose a maintenance conduit assembly. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a maintenance conduit assembly that can effectively clamp the battery body, ensure stability during battery maintenance, and has corresponding limiting components that can keep the clamping plate components in a fixed state when they are opened outward, thus facilitating the loading and unloading process of the battery body. It can also control the three-dimensional movement of the maintenance conduit, so that the injection tube can be accurately inserted into the repair ports of different types of batteries. It also has a reliable reagent injection unit that can effectively control the injection of the homogenizing reagent and avoid injecting air into the battery. Moreover, during the reagent injection, the health of the battery can be detected by an instrument to effectively grasp the battery life, and the problems in the background art can be effectively solved.

[0005] To achieve the above object, the present invention provides the following technical solution: A maintenance conduit assembly, comprising a placement chamber, a clamping and fixing unit, a displacement control unit, and a reagent injection unit;

[0006] Placement chamber: A vertical support plate is fixedly connected to the upper end of the rear side thereof;

[0007] Clamping and fixing unit: Comprising a clamping pipe, a connecting slide bar, a clamping plate, a spring, and a limiting block, a horizontal clamping pipe is fixedly connected to the middle position of each of the left and right sides of the placement chamber. The clamping pipe is composed of two opposite tile-shaped structures in the front and rear. A connecting slide bar is slidably connected to the inside of each clamping pipe. The other end of the connecting slide bar extends into the placement chamber and is fixedly connected to a square clamping plate. A spring is sleeved on the outer side of this section of the connecting slide bar. The outer end of the connecting slide bar is fixedly connected to a limiting block perpendicular to the rod direction. The limiting block passes through the gap between the two tile-shaped structures of the clamping pipe and extends upward;

[0008] Shift control unit: installed on the front side of the vertical support plate;

[0009] Reagent injection unit: installed above the placement chamber.

[0010] The placement chamber is used for placing the battery body to be maintained. When loading the battery, first pull the left and right clamping plates outwards, and pull the connecting slide rod outwards by the limiting block protruding upwards. After pulling the limiting block out of the gap between the clamping pipes, rotate it by a certain angle, so that the limiting block is clamped at the end of the clamping pipe. At this time, the position of the clamping plate is fixed, which can free the operator's hands and make it more convenient to load and unload the battery body. After the battery is loaded, put the limiting block back to its original position between the clamping pipes, and the clamping plate clamps both ends of the battery body under the action of the spring, thereby effectively clamping and fixing the battery body and ensuring the stability of the battery during the catheter maintenance process. The shift control unit is used to control the maintenance catheter to move in three-dimensional space, so as to adapt to various types of batteries and effectively insert the injection pipe into the maintenance port of the battery. The reagent injection unit is used to control the injection of the homogenizing reagent.

[0011] Furthermore, the clamping and fixing unit further includes rubber cushion blocks and spring socket seats. A plurality of rubber cushion blocks are installed on the side of the clamping plate away from the connecting slide rod, and a spring socket seat is fixedly connected to the side of the clamping plate close to the connecting slide rod, and the spring socket seat is sleeved on the outside of the spring. The rubber cushion blocks can protect the battery body when the clamping plate clamps, and can further enhance the clamping stability by increasing the friction with the side of the battery. The spring socket seat is used to limit the spring to ensure that it can work stably on the connecting slide rod.

[0012] Furthermore, the shift control unit includes a clamping chute, an installation slider, a telescopic rod and an installation disk. A horizontal clamping chute is provided at the upper middle position on the front side of the vertical support plate. The clamping chute is a T-shaped structure rotated 90°, and an installation slider is slidably connected inside. The front side of the installation slider is fixedly connected to the rear end of the telescopic rod, and the front end of the telescopic rod is fixedly connected to a horizontally placed installation disk. The clamping chute is used for the installation and clamping of the installation slider and enables the installation slider to slide horizontally. The telescopic rod is used for the installation of the installation disk and enables the installation disk to move longitudinally. The installation disk is used for the installation of the hydraulic cylinder.

[0013] Further, the shift control unit further includes a threaded rod and a hand crank. A horizontal threaded rod is rotatably connected inside the clamping chute. The shaft portion of the threaded rod is of a stepped structure. The thicker end is provided with threads and is threadedly connected to the mounting slider. The thinner section passes through the right side wall of the clamping chute and is fixedly connected to the center of the left side of the hand crank. A hand lever is rotatably connected to an eccentric position on the right side of the hand crank. By rotating the hand crank, the threaded rod can be driven to rotate, and the rotating threaded rod can drive the mounting slider to move horizontally in the clamping chute.

[0014] Further, the shift control unit further includes support rods, a hydraulic cylinder, connection blocks and connection sliding columns. Three support rods are fixedly connected in a circumferential array near the edge position at the upper end of the mounting plate. Three connection blocks are fixedly connected in a circumferential array at the edge position at the upper end of the hydraulic cylinder. The hydraulic cylinder is fixedly connected to the three support rods through the three connection blocks respectively. The telescopic end of the hydraulic cylinder is arranged downward and is fixedly connected to the upper end of the connection sliding column. The connection sliding column is arranged vertically and is slidably connected to the center of the mounting plate. The support rods are used for supporting the hydraulic cylinder, the connection blocks are used for the fixed connection between the hydraulic cylinder and the support rods. The hydraulic cylinder drives the connection sliding column to move up and down, and then drives the injection pipe to lift, so that it can be effectively inserted into the battery.

[0015] Further, the reagent injection unit includes a buffer box, a feed pipe orifice, an injection pipe and a liquid level display block. The lower end of the connection sliding column passes through the mounting plate and an injection pipe is installed inside. A buffer box is installed and fixed on the outer side of this section of the connection sliding column. The inside of the buffer box is hollow and is embedded with a liquid deceleration component. A feed pipe orifice is fixedly connected to the left side of the buffer box. A vertical liquid level display block is embedded on the pipe wall of the injection pipe. The feed pipe orifice is used to connect to an external feeding pipeline. The buffer box is used to slow down the flow rate of the injected reagent. The injection pipe leads the homogenized reagent into the battery. The liquid level display block is made of a transparent glass strip, so that the liquid level in the injection pipe can be observed, and the injection pipe can be pulled out in time when the material is insufficient to avoid injecting air into the battery.

[0016] Further, the reagent injection unit further includes a check valve and an exhaust valve. A check valve is installed at the connection between the feed pipe orifice and the buffer box. An exhaust valve is installed on the upper left side of the buffer box. The check valve is used to block the backflow of the reagent in the buffer box, so as to form a certain pressure inside the buffer box, so that the exhaust valve can effectively discharge the gas mixed in the liquid to the outside.

[0017] Further, the shift control unit further includes a distance sensor and a fastening knob. The distance sensor is installed on the right side of the buffer box, and the fastening knob is installed in the middle of the telescopic rod. The fastening knob is screwed and connected to the telescopic rod. The distance sensor is used to detect the distance between the buffer box and the mounting plate, so that the operator can control the start and stop of the hydraulic cylinder by observing the data on the display screen, effectively avoiding the collision between the buffer box and the mounting plate during the lifting process.

The distance sensor is bidirectionally electrically connected to the display screen, and the input end of the hydraulic cylinder is electrically connected to the output end of the external power supply through the control panel. While injecting the softening reagent into the battery, the measuring instrument can detect various data of the battery, enabling people to understand the health status of the battery. The display screen is used to display the detected data, and the control panel facilitates the control of the start and stop of the hydraulic cylinder.

[0019] Further, it further includes a placement groove, a connection buckle and a corrugated rope. There are two placement grooves, left and right, opened on the front side of the measuring instrument. A connection buckle with a ring at the end is installed inside each placement groove. The other end of the connection buckle is electrically connected to the data port of the measuring instrument through the corrugated rope. The placement groove is used for placing the connection buckle. The connection buckle is buckled on the electrode of the battery through the circular snap ring at the end. While maintaining the electrical connection between the connection buckle and the measuring instrument, the corrugated rope can freely extend, facilitating the hanging of the connection buckle.
