DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 6 , an easily detachable submersible pump cable protector, comprising a fixing mechanism 1 and a rubber ring 2 arranged inside the fixing mechanism 1, wherein the inner wall of the rubber ring 2 is in contact with the surface of the cable, and a plurality of buffers 3 are fixedly connected to the surface of the fixing mechanism 1:

[0024] Furthermore, the fixing mechanism 1 includes a first fixing plate 101 and a second fixing plate 102 that are correspondingly arranged. The first fixing plate 101 is slidably connected with a plurality of locking pins 105 on the front and rear sides. The second fixing plate 102 is fixedly connected with a plurality of limiting sleeves 107 on the front and rear sides of the bottom. A sliding pin 108 is slidably connected inside the limiting sleeve 107. The top of the sliding pin 108 is slidably connected to the bottom of the locking pin 105. A locking slot 106 is provided on the locking pin 105. The left and right ends of the first fixing plate 101 are fixedly connected with locking pieces 112 that are engaged with the locking slot 106.

[0025] When the protector needs to be disassembled, the maintenance personnel can push the connecting rod 116 upward to push the connecting rod 116 out of the corresponding second slot 118 into the first slot 117, and drive the locking card rod 114 to move along the inner wall of the first slot 117 into the positioning sleeve 113 through the connecting rod 116. When the locking card rod 114 slides into the positioning sleeve 113, the locking card rod 114 can be disengaged from the locking card slot 106, thereby separating the locking card rod 114 from the locking pin 105. Then the maintenance personnel pulls the connecting plate 110 upward through the handle 111. When the connecting plate 110 is lifted upward, the locking pin 105 is driven to move upward. When the locking pin 105 follows the connecting plate 110 to move upward, it is driven to gradually move upward along the inner wall of the limiting sleeve 107 until the locking pin 105 is completely disengaged from the limiting sleeve 107. , continue to lift the connecting plate 110 until the locking pin 105 is completely out of the limit ring 104, and the locking pin 105 can be quickly removed from the first fixing plate 101 and the second fixing plate 102 to realize the rapid disassembly of the protector. The device realizes flexible clamping and release of the cable through the sliding connection of the locking pin 105 and the sliding pin 108. When the locking pin 105 slides into the limit sleeve 107 and is locked by the locking piece 112, the cable can be firmly fixed to ensure the stability of the cable during use; conversely, in the unlocked state, the cable can be conveniently and quickly taken out or put in, realizing the convenient disassembly and assembly function, and the opening and closing of the protector can be completed with simple operation, which is conducive to the rapid installation, replacement or maintenance of the cable, and greatly improves the maintenance efficiency and use reliability of the submersible pump cable system.

[0026] Furthermore, a first spring 109 is fixedly connected between the limiting sleeve 107 and the sliding pin 108 , a connecting plate 110 is fixedly connected to the top of the locking pin 105 , and a handle 111 is fixedly connected to the top of the connecting plate 110 .

[0027] When the locking pin 105 moves up and down, the first spring 109 provides the necessary elastic support, so that the locking pin 105 can automatically reset when no external force is applied, ensuring that the locking pin 105 always maintains a stable clamping state of the cable without external force, and also buffers the pressure changes caused by factors such as vibration, reducing excessive tightening or loosening of the cable. The handle is designed to allow maintenance personnel to more conveniently control and operate the protector. By pulling the handle 111 to compress or release the first spring 109, the movement of the locking pin 105 is controlled to achieve the purpose of quickly installing or removing the cable, greatly improving the convenience and work efficiency of on-site operations.

[0028] Furthermore, the locking member 112 includes a positioning sleeve 113, an opposite end of the positioning sleeve 113 is fixedly connected to the first fixing plate 101, and a locking rod 114 is slidably connected inside the opposite side of the positioning sleeve 113, and the locking rod 114 and the locking slot 106 are mutually clamped.

[0029] When the cable needs to be disassembled or adjusted, the handle 111 only needs to be operated in reverse to disengage the locking rod 114 from the locking slot 106, thereby releasing the lock on the locking pin 105, thereby achieving convenient disassembly and assembly of the cable. This design not only ensures the firmness of the cable fixation, but also takes into account the convenience of operation, and meets the design requirements of the easily removable submersible pump cable protector.

[0030] Furthermore, a second spring 115 is fixedly connected between the positioning sleeve 113 and the locking rod 114 . A first slot 117 and a second slot 118 are formed on the front side of the positioning sleeve 113 . The first slot 117 and the second slot 118 are connected to each other.

[0031] Since the second spring 115 provides a restoring force to the locking lever 114, causing it to tend to return to the initial position, the protector is in an unlocked state when no external force is applied, which facilitates quick removal or adjustment of the cable.

[0032] Furthermore, a connecting rod 116 is fixedly connected to the surface of the locking rod 114 . The connecting rod 116 extends to the outside of the positioning sleeve 113 and is mutually engaged with the second slot 118 .

[0033] Due to the clamping design between the connecting rod 116 and the second slot 118, on the one hand, the guidance and stability of the movement of the locking rod 114 are ensured, and on the other hand, a more intuitive and easy-to-apply force location is provided for the operator, so that the locking and unlocking functions can be achieved without going deep into the protector. This simplifies the operating steps and improves work efficiency, while ensuring the safety and convenience of cable maintenance and replacement in complex underground environments.

[0034] Furthermore, the first fixing plate 101 is fixedly connected to the front and rear sides with the mounting plate 103 , and the opposite side of the mounting plate 103 is fixedly connected to a plurality of limiting rings 104 , and the inner wall of the limiting ring 104 is slidably connected to the surface of the locking pin 105 .

[0035] The limiting ring 104 is designed to provide a structure for guiding and limiting the movement trajectory of the locking pin 105, so that the locking pin 105 remains on a predetermined path during movement without deviation or misalignment, thereby ensuring accurate execution of the locking and unlocking actions.

[0036] Furthermore, the buffer member 3 includes a bracket 301 fixed on the surface of the first fixing plate 101 and the second fixing plate 102 , the top of the bracket 301 is rotatably connected to a rotating rod 302 , and a rotating wheel 303 is fixedly sleeved on the surface of the rotating rod 302 .

[0037] The rotating wheel 303 can reduce friction resistance, making the installation and removal of the cable smoother. It can also buffer and disperse stress when the cable is subjected to force, effectively protecting the cable from sudden impact or excessive tension, and extending the service life of the cable.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
