DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides a quick-change device for lithium-ion battery power supply for mining, comprising a housing 1, a protective frame 2 fixedly mounted inside the housing 1, fixing mechanisms 3 provided on both sides of the interior of the protective frame 2, a power block 4 provided inside the protective frame 2, and buffer mechanisms 5 provided on both sides of the power block 4;

[0023] The fixing mechanism 3 includes a pressure rod 31, an inclined rod 32, a clamping block 33, a fixing plate 34 and a return spring 35. One end of the pressure rod 31 overlaps one end of the inclined rod 32, the clamping block 33 is fixedly connected to the other end of the inclined rod 32, and the surface of the clamping block 33 is clamped to the limiting frame 36. The top of the return spring 35 is fixedly connected to the bottom surface of the fixing plate 34.

[0024] The above solution is adopted: the shell 1 provides external protection to prevent external objects, dust, water vapor, etc. from damaging the internal structure and the power block 4; the protection frame 2 serves as the main supporting structure to provide a stable installation frame for the internal components, ensuring the accurate position of each component and the stability of the overall structure; in the process of stabilizing the fixed cover 101, the fixed cover 101 will contact the pressure rod 31, and the pressure rod 31 is subjected to pressure, and the inclined surface at one end of the pressure rod 31 interacts with the inclined surface at one end of the inclined rod 32 to push the inclined rod 32 to move, and the movement of the inclined rod 32 drives the clamping block 33 to snap into the limit frame 36, thereby achieving the desired effect. The power block 4 is fixed. At the same time, the return spring 35 provides the elastic force for the clamping block 33 to maintain the clamping state. When the fixing cover 101 is opened, the pressure on the inclined rod 32 will be released, so that the clamping block 33 is separated from the limit frame 36, realizing the quick replacement of the mining lithium-ion battery power supply, avoiding the situation where the power block 4 is overly dependent on external equipment during disassembly, simplifying the fixing and disassembly operation steps, eliminating the need for complex tools and cumbersome processes, reducing the difficulty of operation, and the operator can easily open the fixing cover 101 to complete the power supply replacement, saving time and energy.

[0025] like Figures 1 to 5 As shown, a fixed cover 101 is provided on the top of the shell 1, and a shock-absorbing pad 21 is also fixedly connected to the inner bottom wall of the protective frame 2. A slide groove and a groove are respectively provided on both sides of the protective frame 2. The slide groove is adapted to the pressure rod 31, and the groove is adapted to the reset spring 35. The fixing plate 34 and the reset spring 35 are both located inside the groove. The opposite ends of the pressure rod 31 and the inclined rod 32 are both inclined, and one side of the limit frame 36 is connected to the surface of the power block 4.

[0026] The above scheme is adopted: a tension spring is fixedly installed on the upper end of the inclined rod 32, and its function is to help the inclined rod 32 to reset. The pressure rod 31 transmits pressure by pressing to push the inclined rod 32 to move. The inclined rod 32 converts the pressure of the pressure rod 31 into horizontal displacement, driving the clamping block 33 to move. The clamping block 33 is clamped with the limit frame 36 to fix the power block 4. The fixing plate 34 fixes one end of the reset spring 35 to ensure that the spring position is stable. The reset spring 35 provides elastic force to keep the clamping block 33 in the clamping state with the limit frame 36 under normal conditions to ensure the fixation of the power block 4.

[0027] like Figures 1 to 5 As shown, the surface of the diagonal rod 32 is slidably connected to a slide rail 321, and the slide rail 321 is fixedly connected to the two ends of the shock-absorbing pad 21. The buffer mechanism 5 includes a fixed block 51 and an elastic column 52. One end of the elastic column 52 is inserted into the interior of the fixed block 51, and one side of the fixed block 51 is fixedly connected to a shock-absorbing pad 511. One side of the shock-absorbing pad 511 is connected to the power block 4, and the other end of the elastic column 52 is connected to the inner wall of the protective frame 2.

[0028] The above solution is adopted: the fixed cover 101 closes the top of the shell 1 to enhance the overall protection performance and prevent foreign matter from entering the interior from above; the shock-absorbing pad 21 absorbs the vibration and impact of the power block 4 in the vertical direction, plays a buffering role, and protects the power block 4; the slide groove provides guidance and activity space for the movement of the pressure rod 31, ensuring the accuracy and stability of the action of the pressure rod 31; the groove accommodates the fixing plate 34 and the reset spring 35, providing space for the expansion and contraction of the reset spring 35, and ensuring the stability of the working environment of the reset spring 35; the slide rail 321 guides the sliding direction of the inclined rod 32 to ensure that the inclined rod 32 moves smoothly, so that the fixing mechanism 3 can operate reliably, and the fixed block 51 is connected The anti-vibration pad 511 and the elastic column 52 are connected to transmit and disperse the buffering force. The elastic column 52 absorbs and buffers the vibration and impact of the power block 4 in the horizontal direction through its own expansion and contraction. The anti-vibration pad 511 further reduces the vibration of the power block 4, avoids direct collision between the power block 4 and the protective frame 2, and provides additional buffering and protection. Since the fixing and disassembly process is relatively smooth, the damage to the power block 4 and related components caused by rough operation is reduced. The fixing mechanism 3 and the buffer mechanism 5 are reasonably designed and highly durable. They can be reused many times, reducing maintenance costs. The disassembly process does not require complex tools and difficult operations, reducing the risk of injury to the operator during the disassembly process.

[0029] The working principle and usage process of the present invention are as follows: the power block 4 is placed in the protective frame 2, and the fixing cover 101 and the outer shell 1 are fixed. In the process of stabilizing the fixing cover 101, the fixing cover 101 will contact the pressure rod 31, and the pressure rod 31 is subjected to pressure. The inclined surface at one end of the pressure rod 31 interacts with the inclined surface at one end of the inclined rod 32 to push the inclined rod 32 to move. The movement of the inclined rod 32 drives the clamping block 33 to be clamped into the limit frame 36, thereby fixing the power block 4. At the same time, the return spring 35 provides the clamping block 33 with elastic force to maintain the clamping state. During the operation of the equipment, the elastic column 52 and the shock-absorbing pad 511 in the buffer mechanism 5 on both sides of the power block 4 will absorb and buffer the horizontal vibration and impact of the power block 4, and the shock-absorbing pad 21 on the bottom wall of the protective frame 2 will absorb the vertical vibration and impact.
