[0038] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0039] This utility model relates to a portable power supply for downhole construction, such as... Figures 1 to 7 As shown, it includes:

[0040] The mobile mechanism 1 is independently and fixedly installed, which facilitates the movement of the entire power supply unit and can adapt to different terrain conditions underground.

[0041] Storage box 2 is mounted on the moving mechanism 1. The outer wall of storage box 2 is provided with a charging plug and a plug hole to facilitate charging of the power supply device and power supply to the construction equipment.

[0042] The sealing cover 3 is equipped with a locking mechanism. The locking mechanism is used to fix the sealing cover 3 to the slot of the storage box 2 to protect the power supply inside the storage box. The sealing cover 3 is equipped with a mounting base 4. The mounting base 4 is made of shock-absorbing material, which can effectively reduce the impact of vibration on the power supply device.

[0043] The locking mechanism consists of multiple connecting mechanisms 5 respectively located at each corner of the storage box 2 and the sealing cover 3;

[0044] The power supply body 6 is installed in the fixing slot of the mounting base 4. The power supply body 6 is electrically connected to the charging plug and the plug hole through wires to realize the input and output of electrical energy.

[0045] The fixing strap 7 is installed on the sealing cover 3 by bolts 9. The fixing strap 7 is used to fix the power supply body 6 and the sealing cover 3. The connection between the fixing strap 7 and the power supply body 6 is provided with shock-absorbing pads 8 to realize the input and output of electrical energy.

[0046] By setting up an independent moving mechanism 1, it can adapt to complex underground terrain conditions, facilitating the rapid movement and positioning of the power supply unit between different construction sites. The design of the storage box 2 and the sealing cover 3, combined with the locking mechanism, can effectively prevent external pollutants such as dust and water vapor from entering the storage box, protecting the power supply unit from damage. The shock-absorbing material mounting seat 6 on the sealing cover 3, and the shock-absorbing pad 8 at the connection between the fixing strap 7 and the power supply unit 6, can effectively reduce the vibration and impact on the power supply during movement or construction, ensuring the stable operation of the power supply unit 6. The power supply unit 6 is fixedly connected to the sealing cover 3 through the fixing strap 7, which is convenient for installation and disassembly, maintenance, and replacement. At the same time, the charging plug and socket on the outer wall of the storage box 2 make the charging and power supply operation of the power supply more convenient. The locking mechanism consists of multiple connecting mechanisms 5, distributed at various corners of the storage box 2 and the sealing cover 3, ensuring the firm fixation of the sealing cover 3 and preventing the sealing cover from loosening or falling off due to vibration during movement or construction, further improving the safety and reliability of the device.

[0047] As a preferred option, such as Figures 1 to 4 As shown, the connecting mechanism 5 includes:

[0048] Positioning post 51 is set at the corner of storage box 2. Positioning post 51 is provided with a guide channel. The guide channel has an L-shaped structure and a positioning groove is provided at the end of the guide channel.

[0049] Mounting component 52 is rotatably mounted at the positioning hole at the corner of the sealing cover 3, and a positioning pin 53 is slidably provided at the shaft hole of mounting component 52. The positioning pin 53 rotates synchronously with mounting component 52, and the positioning pin 53 is slidably connected with the guide groove.

[0050] The fixing part 54 is installed on the positioning pin 53, and the fixing part 54 is provided with a spring 55. The other end of the spring 55 is installed on the mounting part 52. The spring 55 is used to provide a restoring force when the distance between the fixing part 54 and the mounting part 52 increases, so as to lock the positioning pin (53) and the positioning groove.

[0051] The guide mechanism 56 is set on the sealing cover 3. The guide mechanism 56 is used to position the storage box 2 and the sealing cover 3 at their installation positions.

[0052] The working principle of this device is as follows:

[0053] When the sealing cover 3 needs to be installed on the storage box 2, the sealing cover 3 and the storage box 2 are initially positioned by the guide mechanism 56, so that the mounting part 52 on the sealing cover 3 corresponds to the position of the positioning post 51 on the storage box 2. Then, the mounting part 52 is rotated. Since the positioning pin 53 rotates synchronously with the mounting part 52, the positioning pin 53 will enter the guide groove on the positioning post 51. As the positioning pin 53 slides along the L-shaped guide groove, the distance between the fixing part 54 and the mounting part 52 will gradually increase, and the spring 55 will be stretched. When the positioning pin 53 slides to the positioning groove position at the end of the guide groove, under the action of the spring 55, the positioning pin 53 is pulled into the positioning groove, realizing the locking of the positioning pin 53 and the positioning groove, thereby firmly fixing the sealing cover 3 on the storage box 2.

[0054] When it is necessary to open the sealing cover 3, manually apply external force to overcome the elastic force of the spring 55, pull the positioning pin 53 out of the positioning groove, and then rotate the mounting part 52 in the opposite direction to make the positioning pin 53 slide out along the guide groove, so that the sealing cover 3 can be removed from the storage box 2.

[0055] The connection mechanism 5 is located at each corner of the storage box 2 and the sealing cover 3, ensuring the sealing cover 3 is firmly fixed and preventing it from loosening or falling off due to vibration during movement or construction. This further improves the safety and reliability of the portable power supply device for underground construction of this utility model.

[0056] As a preferred option, such as Figures 1 to 4 As shown, the guide mechanism 56 includes:

[0057] Mounting post 56a is installed on sealing cover 3, and mounting post 56a is coaxial with mounting part 52;

[0058] The guide post 65b is coaxially mounted on the mounting post 56a, and the guide post 65b is slidably mounted in conjunction with the inner hole of the positioning post 51. The connection end between the guide post 65b and the positioning post 51 is chamfered.

[0059] With the aforementioned guide mechanism 56, the positions of the storage box 2 and the sealing cover 3 can be accurately positioned during installation and disassembly, enabling the connecting mechanism 5 to work smoothly. This further ensures the accuracy and firmness of the connection between the sealing cover 3 and the storage box 2, and improves the overall performance and reliability of the portable power supply device for downhole construction of this utility model.

[0060] As a preferred option, such as Figures 1 to 4 As shown, the mounting part 52 is provided with a regular hexagonal inner groove, and the regular hexagonal inner groove is coaxially arranged with the locating pin 53;

[0061] By providing a regular hexagonal inner groove on the mounting part 52 and aligning it with the positioning pin 53 on the same axis, a more convenient and reliable method is provided for the installation and removal of the sealing cover 3 and the storage box 2.

[0062] As a preferred option, such as Figures 1 to 6 As shown, the moving mechanism 1 includes:

[0063] The base 11 is located at the bottom of the storage box 2, and a fixing groove is provided on the outer wall of the base 11. The first filter screen 12 with the same structure as the fixing groove is installed in the fixing groove.

[0064] The Foma wheel set 13 is installed at the bottom of the base 11;

[0065] The heat dissipation mechanism 14 is set on the base 11 and is located at the heat dissipation slot of the storage box 2, and is used to dissipate heat from the power supply body 6 inside the storage box 2.

[0066] The working principle of the moving mechanism 1 of this device is as follows:

[0067] When the power supply unit needs to be moved, the operator unlocks the fan wheel in fan wheel assembly 13, pushes the power supply unit, and the fan wheel begins to roll, allowing the power supply unit to move across different terrains underground. Because the fan wheel has omnidirectional rotation capabilities, the power supply unit can flexibly change its direction of movement to adapt to the complex underground working environment. Once the power supply unit has reached the target working location, the operator locks the fan wheel, ensuring the power supply unit remains stably in the designated position.

[0068] During operation, the power supply unit 6 generates heat. The cooling fan in the heat dissipation mechanism 14 starts running. Outside air first passes through the first filter 12 to remove dust and debris, and then enters the storage box 2 through the heat dissipation channel. The cool air exchanges heat with the power supply unit 6, carrying away heat and lowering the temperature of the power supply unit 6. The hot air is then discharged from the storage box 2 through the heat dissipation channel, completing the heat dissipation cycle. The first filter 12 effectively prevents dust and other contaminants from entering the storage box 2, protecting the normal operation of the power supply unit 6.

[0069] As a preferred option, such as Figures 1 to 6 As shown, the heat dissipation mechanism 14 includes;

[0070] A drive motor 14a is mounted on a base 11, and a drive shaft 14b is coaxially mounted on the output end of the drive motor 14a.

[0071] Assembly 14c is coaxially mounted on drive shaft 14b, and assembly 14c is provided with heat dissipation fan blade assembly 14d;

[0072] A second filter 14e is installed in the heat dissipation slot of the storage box 2, and the drive shaft 14b is rotated and installed in conjunction with the positioning hole of the second filter 14e.

[0073] With the above-mentioned heat dissipation mechanism 14, the power supply body 6 inside the storage box 2 can be efficiently cooled, while preventing external pollutants from entering. This ensures the stable operation of the power supply body 6 in the complex underground environment and further improves the reliability and service life of the portable power supply device for underground construction of this utility model.

[0074] As a preferred option, such as Figures 1 to 2 As shown, a movable handle 10 is provided on the sealing cover 3;

[0075] By providing a movable handle 10 on the sealing cover 3, the installation and removal of the sealing cover 3 and the movement and adjustment of the power supply device are greatly facilitated, thus improving the work efficiency of the operators.

[0076] The present invention relates to a portable power supply for downhole construction. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0077] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
