[0002] Mines contain a large number of mechanical devices, such as coal mining machines, conveyor belts, and drilling rigs. During operation, these devices can cause mechanical impacts or pulling on surrounding cables, especially in deep mines or narrow tunnels where cables are exposed and easily collided with or squeezed by heavy objects, equipment, or ore. This can lead to problems such as short circuits, breaks, and damage to the insulation layer. At the same time, some environments in mines have special conditions such as high temperature, humidity, and corrosion, and there are flammable and explosive substances such as coal dust. In such an environment, these factors can corrode exposed cables, affecting their performance and service life. If the cables are broken or damaged, electric arcs can be generated, which can lead to fires or explosions. Utility Model Content

[0003] The purpose of this utility model is to provide a cable protection device to solve the problem that in deep wells or relatively narrow mine tunnels, cables are exposed and are easily hit and squeezed by heavy objects, equipment or ore, which can lead to short circuits, breakage, insulation damage, and cable corrosion under special conditions such as high temperature, humidity and corrosion.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cable protection device, comprising a protective shell, a connecting device, and a clamping device. The protective shell is composed of an upper shell and a lower shell joined together. The upper and lower shells are symmetrically provided with semi-circular arc placement grooves. The upper and lower shells are symmetrically and evenly provided with a plurality of clamping devices. The bottom left and right sides of the upper shell are symmetrically connected to connecting plates, with limiting grooves formed on the connecting plates. The top left and right sides of the lower shell are provided with connecting grooves corresponding to the connecting plates, which cooperate with the connecting plates. The left and right ends of the lower shell are respectively provided with positioning grooves, and connecting devices are provided within the positioning grooves.

[0005] The connecting device includes a sliding rod, a return spring, and a positioning plate. A plurality of through holes are evenly distributed in the positioning groove, and a plurality of sliding rods are inserted into the through holes, with the sliding rods slidably fitted onto the lower housing. A positioning plate is connected to the top end of each sliding rod, and a limit ring is connected to the other end. The positioning plate cooperates with the limit groove of the connecting plate. A return spring is provided at the end of the positioning plate away from the connecting plate, and is sleeved on the sliding rod. One end of the return spring abuts against the positioning plate, and the other end abuts against the inner wall of the positioning groove, used to reset the positioning plate.

[0006] The clamping device includes an arc-shaped base plate, a clamping plate, springs, a first connecting rod, and a second connecting rod. The arc-shaped base plate is evenly arranged in the semi-circular arc placement grooves of the upper and lower housings. An auxiliary groove is formed at an angle on the arc-shaped base plate, and several springs are arranged in the auxiliary grooves. The top of the springs is connected to the clamping plate, and the clamping plate abuts against the outer circumference of the cable. A pair of first connecting rods are respectively hinged to the left and right sides of the middle of the clamping plate. The first connecting rods are located at the front and rear ends of the left and right sides of the clamping plate. The other end of the first connecting rod is respectively hinged to the second connecting rod, and the other end of the second connecting rod is hinged to the arc-shaped base plate.

[0007] Preferably, the clamping plate is arc-shaped and has a silicone protective layer on the end face that contacts the cable to reduce wear on the cable.

[0008] Preferably, the front and rear ends of the upper and lower shells are symmetrically connected with semi-circular waterproof covers, and the ends of the waterproof covers away from the protective shells extend toward the center and abut against the outer circumference of the cable.

[0009] Preferably, the waterproof cover has a sealing gasket at the joint.

[0010] Preferably, both the upper and lower housings are made of transparent epoxy resin, which facilitates the identification of cable colors.

[0011] Preferably, the contact end between the connecting plate and the positioning plate is set at an angle.

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

[0013] By placing the cable inside the protective housing, which consists of two joined shells, the lower shell has a semi-circular groove to accommodate the cable. The outer circumference of the cable is in close contact with the curved end face of the clamping plate, while a spring at the bottom of the clamping plate provides support for the cable. Next, the upper shell is installed, ensuring its clamping plate contacts the outer circumference of the cable's tip, thus clamping and securing the cable and increasing its stability.

[0014] During installation, the connecting plate of the upper housing is inserted into the connecting groove of the lower housing, and the beveled end of the connecting plate contacts the positioning plate, pushing the positioning plate to slide. At the same time, the positioning plate begins to compress through contact with the return spring. When the connecting plate is fully engaged with the connecting groove, the positioning plate will automatically return to its original position under the force of the return spring, entering the limiting groove on the connecting plate, thereby fixing the position of the connecting plate and ensuring a firm connection between the upper and lower housings.

[0015] During disassembly, users only need to pull the slide bar to slide the positioning plate to unlock the connection, making disassembly convenient. At the same time, the waterproof covers at both ends of the protective shell are designed with an appropriate slope to help water droplets slide off, avoid water accumulation, effectively prevent water droplets from entering the protective shell, and ensure the long-term reliability of the equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1-6This utility model provides an embodiment of a cable protection device, including a protective shell, a connecting device 4, and a clamping device 6. The protective shell is composed of an upper shell 1 and a lower shell 2, which together form a whole to protect the internal cables and prevent them from being exposed and easily damaged by heavy objects, equipment, or ores. Both the upper shell 1 and the lower shell 2 are made of transparent epoxy resin, making it easy to identify the cable color. The transparent material also allows users to clearly see the internal cables, facilitating cable location, maintenance, and troubleshooting. This is crucial for long-term equipment maintenance, reducing the complexity and time of repairs and simplifying inspection and maintenance. The upper shell 1 and the lower shell 2 each have symmetrically arranged semi-circular placement slots, which, when joined together, form a circular placement slot to accommodate the cables. The upper shell 1 and the lower shell 2 each have symmetrically and evenly arranged clamping devices 6, which are mainly used to clamp the cables, ensuring their safety. The upper housing 1 is positioned in the center of the protective shell to maintain alignment and prevent displacement due to vibration or external forces, while also preventing external wear and tear on the cable. The bottom of the upper housing 1 has symmetrical connecting plates 5 on both sides. These connecting plates 5 work in conjunction with the connecting device 4 to form a stable whole between the upper housing 1 and the lower housing 2, thus housing the cable within the semi-circular placement groove for cable protection. A limiting groove is provided on the connecting plate 5, which works in conjunction with the positioning plate 403 of the connecting device 4. The positioning plate 403 fits into the limiting groove, ensuring the cable is securely attached. The position of the connecting plate 5 is defined to connect the upper shell 1 and the lower shell 2. Connecting grooves are formed on the left and right sides of the top of the lower shell 2, corresponding to the connecting plate 5. These grooves accommodate the connecting plate 5 and are shaped accordingly. The bottom of the groove abuts against the bottom of the connecting plate 5, and the top of the groove abuts against the bottom of the upper shell 1. This further ensures the docking accuracy of the shells and guarantees the tightness and stability of the shell assembly. The connecting grooves cooperate with the connecting plate 5. Positioning grooves are formed on the left and right sides of the lower shell 2, and connecting devices 4 are installed within these positioning grooves.

[0028] The connecting device 4 includes a slide rod 401, a return spring 402, and a positioning plate 403. A plurality of through holes are evenly distributed on the positioning groove. These through holes primarily provide the sliding range of the slide rod 401. Several slide rods 401 are inserted into the through holes, and the slide rods 401 slidably engage with the lower housing 2. The slide rods 401 can slide within the positioning groove. In some embodiments, the slide rod 401 can be a single unit or connected as a whole by a connecting rod. The top end of the slide rod 401 is connected to the positioning plate 403. The positioning plate 403 is located at the top end of the slide rod 401 and connects to the... The limiting groove of plate 5 restricts the position of connecting plate 5 for positioning and fixing. A limiting ring is connected to the other end to prevent the slide rod 401 from sliding out of the predetermined range and falling off. Positioning plate 403 cooperates with the limiting groove of connecting plate 5. A return spring 402 is provided at the end of positioning plate 403 away from connecting plate 5. The contact end between connecting plate 5 and positioning plate 403 is inclined. During descent, the end of positioning plate 403 away from slide rod 401 abuts against the inclined surface. The inclined surface facilitates the cooperation between connecting plate 5 and positioning plate 403, allowing it to fit onto the slide rod. On rod 401, one end of return spring 402 abuts against positioning plate 403, and the other end abuts against the inner wall of positioning groove, used to reset positioning plate 403. When the device is not in working state, return spring 402 returns positioning plate 403 to its original position, ensuring the stability of the device. In the initial position of positioning plate 403, the end of positioning plate 403 away from sliding rod 401 is located on the center line of connecting groove. When connecting plate 5 is inserted, the inclined end of connecting plate 5 abuts against positioning plate 403, thereby sliding positioning plate 403, and at the same time, the return spring 402 abuts against the positioning plate 403. 2. The connecting plate 5 is pressed against the inner wall of the positioning groove, and the sliding rod 401 is pushed away. After the connecting plate 5 is completely lowered, the positioning plate 403 slides due to the force of the reset spring 402, thereby abutting against the limiting groove and limiting the position of the connecting plate 5, so that the upper housing 1 and the lower housing 2 are connected into a whole. When repairing the internal cables, the sliding rod 401 in the middle of the positioning plate 403 is pulled, which moves the entire positioning plate 403 away from the limiting groove, thereby unlocking the connecting plate 5 and unlocking the upper housing 1 and the lower housing 2, so as to disassemble and inspect the inside.

[0029] Example 2: Please refer to Figure 4-5 Based on Example 1, it also has the following structure:

[0030] The clamping device 6 includes an arc-shaped base plate, a clamping plate 601, springs 602, a first connecting rod 603, and a second connecting rod 604. The arc-shaped base plate is evenly arranged in the semi-circular arc placement groove between the upper housing 1 and the lower housing 2. The arc-shaped base plate provides a stable support foundation to help fix the clamping device 6 in the semi-circular arc placement groove between the upper housing 1 and the lower housing 2. The arc-shaped base plate has auxiliary grooves at an angle, and several springs 602 are installed in the auxiliary grooves. The main function of the springs 602 is to provide elastic force to push the clamping plate 601 to move and maintain the contact force between the clamping plate 601 and the cable. Through the action of the springs 602, the clamping device 601 can move. The spring 602 is designed to maintain a clamping grip on the cable even without external force, increasing cable stability. A clamping plate 601 is connected to the top of the spring 602. The clamping plate 601 is the part that contacts the outer side of the cable and directly undertakes the task of clamping the cable. Its arc-shaped design allows it to conform to the outer circumference of the cable, maintaining a stable clamping force. Meanwhile, the spring 602 at the bottom provides an adjustable range of motion, facilitating the clamping of different cables. The clamping plate 601 is arc-shaped, and the contact surface with the cable has a silicone protective layer to reduce wear on the cable. The arc-shaped design effectively increases the contact area with the cable, conforms to the cable's shape, ensures uniform clamping force, and prevents the cable from being damaged by external forces. To prevent damage caused by uneven force and to reduce damage to the cable from excessive local pressure, the clamping plate 601 abuts against the outer circumference of the cable. A pair of first connecting rods 603 are hinged to the left and right sides of the middle of the clamping plate 601, respectively. The first connecting rods 603 are located at the front and rear ends of the left and right sides of the clamping plate 601. The other end of each first connecting rod 603 is hinged to a second connecting rod 604, the other end of which is hinged to an arc-shaped base plate. The positions where the first connecting rods 603 and 604 are hinged to the clamping plate 601 are symmetrical. The main function of the first connecting rods 603 and 604 is to provide auxiliary support to the clamping plate 601. When the clamping plate 601 is pressed down, the spring 602 is pressed down, driving the first connecting rod 603 and the second connecting rod 604 to rotate, providing auxiliary support and positioning to prevent the clamping plate 601 from shifting and causing wear on the cable during clamping. In use, the cable is placed on the clamping plate 601 of the lower housing 2, and then the upper housing 1 is installed, so that the clamping device 6 of the upper housing 1 and the clamping device 6 of the lower housing 2 are spliced ​​into a whole. Then the clamping plate 601 abuts against the outer circumference of the cable, while squeezing the spring 602. The first connecting rod 603 and the second connecting rod 604 rotate, providing auxiliary support for the clamping plate 601, and the clamping plate 601 clamps the cable firmly.

[0031] Example 3: Please refer to Figure 1 Based on Example 1, it also has the following structure:

[0032] The upper housing 1 and the lower housing 2 are symmetrically connected to semi-circular waterproof covers 3 on their front and rear ends. The waterproof covers 3 prevent water or other liquids from entering the equipment and protect the electrical connection parts from moisture. The top extends to the outside of the cable and contacts the outer circumference of the cable to form a closed waterproof barrier. At the same time, the slope allows water droplets to slide off and avoid entering the interior. The connection of the waterproof covers 3 is equipped with a sealing gasket. The upper housing 1 and the lower housing 2 are spliced ​​into a whole. The sealing gasket ensures that the connection is tightly sealed to prevent water droplets from entering the interior. The end of the waterproof cover 3 away from the protective shell extends towards the center and contacts the outer circumference of the cable.
