[0002] The emergency power supply device for substation communication is a backup power solution designed specifically for the substation communication system, aiming to ensure that the communication system can continue to operate normally in case of main power failure or other emergencies, and avoid production stagnation or safety accidents caused by communication interruption.

[0003] Patent document CN204836876U discloses an elevator emergency power supply box, "including a box body and a door. A power module and a mounting plate are installed in the box body, and the power module and the mounting plate are independent of each other and connected by cables; the power module is installed on the back plate of the box body facing the door; the mounting plate is provided with a function control board and a drive circuit board, and the mounting plate is installed in front of the power module in a manner parallel to the back plate. The control module and the power module are relatively independent. When the power module needs to be replaced, only by flipping the mounting plate, the power module can be completely exposed in front of the operator. When the user maintains and replaces the battery device, it will not affect the control module on the mounting plate, and the operability is enhanced." However, the elevator emergency power supply box in the above-mentioned disclosed document mainly considers the convenience of replacing the battery device, and does not consider that when the emergency power supply device for substation communication is installed in a place with heavy rain or close to water sources, the humidity of the surrounding environment will be relatively high, which will cause the humidity of the internal environment of the emergency power supply device for substation communication to increase, make the battery pack damp, and thus cause damage to the emergency power supply device for substation communication. Therefore, it is necessary to research an emergency power supply device for substation communication, which can prevent the internal part of the emergency power supply device from getting damp. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an emergency power supply device for substation communication, so as to solve the technical problem of damage caused by moisture absorption of the emergency power supply device mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An emergency power supply device for substation communication, including a box body and a battery pack. Grooves are symmetrically arranged inside the box body, and threaded grooves are arranged on the inner walls of the grooves. Drying blocks are placed in the grooves, and a hollow box is detachably connected in the grooves, and the drying blocks are located inside the hollow box.

[0006] Preferably, a threaded joint is fixedly installed at the bottom end of the hollow box, and the hollow box is threadedly connected with the groove through the threaded joint.

[0007] Preferably, a base is fixedly installed at the bottom end of the box body. Square grooves are symmetrically arranged inside the base. Motors are arranged inside the square grooves. The output ends of the motors are fixedly connected with lead screws. Threaded rings are in threaded connection with the lead screws. Moving frames are fixedly connected to the threaded rings. Self-locking universal wheels are installed at both ends of the moving frames.

[0008] Preferably, two groups of sliding grooves are symmetrically installed on the inner walls of the square grooves. Sliders are slidably installed inside the sliding grooves, and the other ends of the sliders are fixedly connected with the moving frames.

[0009] Preferably, a connecting block is fixedly installed on the motor, and the connecting block is fixedly installed on the inner wall of the square groove by screws.

[0010] Preferably, a protection board is hinged to the box body, and the protection board is used for protecting the battery pack.

[0011] Preferably, a handle is fixedly installed on the protection board, and the handle is used for pulling the protection board.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model can continuously prevent moisture in the box body through the arranged drying blocks that are easy to replace. First, place the drying blocks in the grooves, and then the hollow boxes are in threaded connection with the grooves through threaded joints to limit the positions of the drying blocks. The drying blocks will contact the air inside the box body through the holes on the hollow boxes. Since the drying blocks are made of magnesium chloride material, and the drying blocks made of magnesium chloride material have a fast moisture absorption speed and continuous moisture absorption ability, the moisture in the air inside the box body can be adsorbed through the drying blocks, so that the inside of the box body is kept dry, avoiding moisture intrusion into the emergency power supply device and causing corrosion and damage to the battery pack. By setting the drying blocks, the stability and reliability of the emergency power supply device for substation communication are improved;

[0014] 2. The utility model is convenient for moving the box body by installing self-locking universal wheels. First, start the motor to drive the screw rod to rotate. The screw rod pushes the moving frame downward through the threaded ring. At the same time, the moving frame drives the self-locking universal wheels to move out of the inside of the square groove, so that the self-locking universal wheels contact the ground. Then, just push the box body to move it through the self-locking universal wheels. After moving to the appropriate position, start the motor to rotate in the reverse direction. After the self-locking universal wheels are self-locked and received into the self-locking base, the box body will directly contact the ground through the self-locking base, avoiding the shaking of the emergency power supply device, improving the flexibility of the emergency power supply device for substation communication and not affecting the stability of the box body in contact with the ground. The self-locking universal wheels can be locked through the locking structure. When the emergency power supply device is used in a slope environment, the universal wheels can be locked through the locking structure. The anti-slip material of the self-locking universal wheels increases the stability of the emergency power supply device and further increases the adaptability of the emergency power supply device to various environments.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0022] Please refer toFigure 1 , Figure 2 and Figure 3 , an emergency power supply device for substation communication, comprising a box body 1 and a battery pack 2. A protection plate 17 is hingedly connected to the box body 1. The protection plate 17 is used to protect the battery pack 2. A handle 18 is fixedly installed on the protection plate 17. The handle 18 is used to pull the protection plate 17. Grooves 13 are symmetrically arranged inside the box body 1, and threaded grooves are arranged on the inner walls of the grooves 13. Desiccant blocks 14 are placed in the grooves 13. A hollow box 15 is detachably connected in the grooves 13, and the desiccant blocks 14 are located inside the hollow box 15. A threaded joint 16 is fixedly installed at the bottom end of the hollow box 15, and the hollow box 15 is threadedly connected to the groove 13 through the threaded joint 16. By being able to provide stable DC or AC power, the emergency device provides emergency power for substation communication through the battery pack 2. However, when the emergency power supply device for substation communication is installed in a rainy area or near a water source, the humidity of the surrounding environment will be relatively high, which will cause the humidity of the internal environment of the emergency power supply device for substation communication to increase, making the battery pack 2 damp, thus resulting in damage to the emergency power supply device for substation communication. When moisture-proofing is required inside the box body 1, continuous moisture-proofing of the inside of the box body 1 is achieved through the provided desiccant blocks 14 that can be conveniently replaced. First, place the desiccant blocks 14 in the grooves 13, and then the hollow box 15 is threadedly connected to the groove 13 through the threaded joint 16 to limit the position of the desiccant blocks 14. The desiccant blocks 14 will contact the air inside the box body 1 through the holes on the hollow box 15. Since the desiccant blocks 14 are made of magnesium chloride material, and the desiccant blocks 14 made of magnesium chloride material have a fast moisture absorption speed and continuous moisture absorption ability, the moisture in the air inside the box body 1 can be adsorbed by the desiccant blocks 14, keeping the inside of the box body 1 dry and preventing moisture from invading the emergency power supply device and corroding and damaging the battery pack 2. By setting the desiccant blocks 14, the stability and reliability of the emergency power supply device for substation communication are improved.

[0023] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5, a base 3 is fixedly installed at the bottom end of the box body 1. Square grooves 4 are symmetrically arranged inside the base 3. A motor 5 is arranged inside the square groove 4. The output end of the motor 5 is fixedly connected with a lead screw 6. A threaded ring 7 is threadedly connected to the lead screw 6. A moving frame 8 is fixedly connected to the threaded ring 7. Self-locking universal wheels 9 are installed at both ends of the moving frame 8. When it is necessary to move the box body 1, it is convenient to move the box body 1 by installing the self-locking universal wheels 9. First, start the motor 5 to drive the lead screw 6 to rotate. The lead screw 6 pushes the moving frame 8 to move downward through the threaded ring 7. At the same time, the moving frame 8 will drive the self-locking universal wheels 9 to move out of the inside of the square groove 4, so that the self-locking universal wheels 9 are in contact with the ground. Then, just push the box body 1 to move it through the self-locking universal wheels 9. After moving to a suitable position, start the motor 5 to rotate in the reverse direction, so that the self-locking universal wheels 9 are retracted into the square groove 4 again. After the self-locking universal wheels 9 are received into the base 3, the box body 1 will be in direct contact with the ground through the base 3. Friction is generated between the box body 1 and the ground by the gravity of the box body 1, avoiding the shaking of the emergency power supply device, improving the flexibility of the emergency power supply device for substation communication and not affecting the stability of the contact between the box body 1 and the ground at the same time. The self-locking universal wheels 9 can be locked through a locking structure. When the emergency power supply device is used in a slope environment, the base 3 cannot make good contact with the ground to provide good stability. At this time, the self-locking universal wheels 9 can be pushed out, and at the same time, the universal wheels are locked through the locking structure. The anti-slip material of the self-locking universal wheels 9 increases the stability of the emergency power supply device, further increasing the adaptability of the emergency power supply device to various environments.

[0024] Please refer to Figure 4 , two groups of sliding grooves 11 are symmetrically installed on the inner wall of the square groove 4. Sliding blocks 12 are slidably installed inside the sliding grooves 11, and the other end of the sliding block 12 is fixedly connected to the moving frame 8. The sliding grooves 11 and the sliding blocks 12 are used to limit the moving frame 8.

[0025] Please refer to Figure 5 , a connecting block 10 is fixedly installed on the motor 5, and the connecting block 10 is fixedly installed on the inner wall of the square groove 4 through screws. The motor 5 is fixed inside the square groove 4 through the connecting block 10.

[0026] Working principle: When moisture-proofing is required inside the box body 1, continuous moisture-proofing of the inside of the box body 1 is carried out by means of a conveniently replaceable drying block 14. First, the drying block 14 is placed in the groove 13, and then the hollow box 15 is threadedly connected to the groove 13 through the threaded joint 16 to limit the position of the drying block 14. The drying block 14 will contact the air inside the box body 1 through the holes on the hollow box 15. Since the drying block 14 is made of magnesium chloride, and the drying block 14 made of magnesium chloride has a fast moisture absorption speed and continuous moisture absorption capacity, the moisture in the air inside the box body 1 can be adsorbed by the drying block 14, keeping the inside of the box body 1 dry and preventing moisture from invading the emergency power supply device and corroding and damaging the battery pack 2. By setting the drying block 14, the stability and reliability of the emergency power supply device for substation communication are improved. When the box body 1 needs to be moved, it is convenient to move the box body 1 by installing self-locking universal wheels 9. First, start the motor 5 to drive the screw rod 6 to rotate. The screw rod 6 pushes the moving frame 8 downward through the threaded ring 7. At the same time, the moving frame 8 will drive the self-locking universal wheels 9 out of the inside of the square groove 4, making the self-locking universal wheels 9 contact the ground. Then, just push the box body 1 to move it through the self-locking universal wheels 9. After moving to the appropriate position, start the motor 5 to rotate in the reverse direction. After the self-locking universal wheels 9 are retracted into the base 3, the box body 1 will directly contact the ground through the base 3. Friction is generated between the box body 1 and the ground due to the gravity of the box body 1, avoiding the shaking of the emergency power supply device, improving the flexibility of the emergency power supply device for substation communication and not affecting the stability of the contact between the box body 1 and the ground. The self-locking universal wheels 9 can be locked through the locking structure. When the emergency power supply device is used in a slope environment, the base 3 cannot make good contact with the ground to provide good stability. At this time, the self-locking universal wheels 9 can be pushed out and the universal wheels can be locked through the locking structure. The anti-slip material of the self-locking universal wheels 9 increases the stability of the emergency power supply device and further increases the adaptability of the emergency power supply device to various environments.
