Description

Technical Field

[0001] This utility model relates to the field of submersible pump cable installation technology, and in particular to a submersible pump installation cable anti-friction fixing device. Background Technology

[0002] In harsh operating conditions such as deep wells, submersible pumps, and mobile pumps, the reliability of pump cables directly affects the operational safety and lifespan of the entire pumping system. During pump start-up and shutdown, water flow pulsation, or movement and dragging, the cable is subjected to alternating stress, especially at fixed points, bends, and interfaces, where stress concentration is prone to occur, accelerating material fatigue and cracking. Preventing friction on pump cables is a crucial issue, directly impacting equipment safety and service life. Cable damage can lead to short circuits, electrical leaks, or even pump burnout.

[0003] Currently, during installation, the power supply and signal cables of return pumps and submersible pumps in wastewater treatment plants are typically submerged in the pump pit along with stainless steel lifting chains. Due to water flow impact, pump body vibration, and hoisting operations, long-term and repeated relative friction and compression occur between the cables and the metal chains, leading to damage to the cable sheath, exposure of internal wires, or even breakage. This can cause safety accidents such as leakage, short circuits, and equipment shutdowns. Furthermore, frequent cable replacements are required, increasing maintenance costs and equipment downtime. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where cables are typically submerged in the pump pit along with stainless steel lifting chains. Due to water flow impact, pump body vibration, and hoisting operations, long-term and repeated relative friction and compression occur between the cable and the metal chain, leading to damage to the cable sheath, exposure of internal wires, and even breakage. This can cause safety accidents such as leakage, short circuits, and equipment downtime. Furthermore, frequent cable replacements are required, increasing maintenance costs and equipment downtime. This invention provides a submersible pump cable anti-friction fixing device.

[0005] The purpose of this utility model is achieved through the following technical solution: a submersible pump mounting cable anti-friction fixing device, including a lifting chain and a cable installed on the upper part of the submersible pump, a plurality of equidistant connecting rods are arranged between the lifting chain and the cable, a mounting base is installed at one end of the connecting rod near the cable, a fixed clamp plate and a movable clamp plate are installed on the mounting base, both the fixed clamp plate and the movable clamp plate are arc-shaped, and the end of the movable clamp plate near the mounting base is rotatably connected to the mounting base, and a protective sleeve for connecting the cable is installed between the fixed clamp plate and the movable clamp plate; An L-shaped fixing plate corresponding to the movable clamping plate is installed at the end of the fixed clamping plate away from the mounting base. A fastening bolt is threaded on the L-shaped fixing plate. One end of the fastening bolt passes through the L-shaped fixing plate and is fitted with a fastening block corresponding to the movable clamping plate. The fastening block is in contact with the side of the movable clamping plate away from the protective sleeve.

[0006] By setting up multiple sets of fixed clamps and moving clamps on the mounting bases, which work together with the protective sleeves, the cables can be fixedly clamped at equal intervals. The connecting rods and mounting bases work together to maintain a certain distance between the lifting chain and the cables, avoiding relative friction and compression between them. At the same time, the protective sleeves protect the cables, effectively extending their service life and ensuring the stability of the submersible pump's operation.

[0007] A further technical solution involves an L-shaped fixed plate with slots corresponding to the movable clamping plate. The width of the slots is greater than that of the movable clamping plate. By setting fastening bolts and threaded connections to the L-shaped fixed plate, the movable clamping plate is pushed by fastening blocks to compress the protective sleeve and the cable, ensuring a stable connection between the cable and the protective sleeve and guaranteeing the protective effect of the protective sleeve on the cable. The slots allow for the flexibility of the movable clamping plate's rotation when the fastening blocks push it, avoiding interference between the curved movable clamping plate and the L-shaped fixed plate. The rotatable movable clamping plate, in conjunction with the fastening bolts and fastening blocks, can clamp and fix cables of different sizes, meeting the applicability of the equipment.

[0008] A further technical solution is that the protective sleeve is a rubber sleeve, with a cable placement groove corresponding to the cable in the middle of the protective sleeve, and an opening groove on one side of the protective sleeve that communicates with the cable placement groove. By setting the protective sleeve to be a rubber sleeve, the cable can be further protected. By setting the opening groove, it is easy to insert the cable into the cable placement groove from the side of the cable, thereby improving the convenience of installing the protective sleeve and the cable.

[0009] A further technical solution is to provide anti-slip textures on the outer side of the protective sleeve, corresponding to the fixed and movable clamping plates. By providing anti-slip textures on the outer side of the protective sleeve, the friction between the protective sleeve and the fixed and movable clamping plates can be increased, thereby further improving the stability of the clamping between the fixed and movable clamping plates and the protective sleeve.

[0010] A further technical solution is to provide a wear-resistant layer on the side of the moving clamp and the fastening block that are close to each other. By providing a wear-resistant layer on the moving clamp and the fastening block, the wear resistance of the moving clamp and the fastening block can be improved when the fastening block rotates with the fastening bolt and rubs against the moving clamp, thereby increasing the service life of the moving clamp and the fastening block.

[0011] This utility model has the following advantages: By setting multiple sets of fixed clamping plates and moving clamping plates on the mounting base and cooperating with the protective sleeve, the cable can be fixed and clamped at equal distances. The connecting rod and the mounting base cooperate to make a certain distance between the lifting chain and the cable, so as to avoid relative friction and compression between the lifting chain and the cable. At the same time, the protective sleeve protects the cable, effectively extending the service life of the cable and ensuring the stability of the submersible pump operation.

[0018] like Figures 1-4 As shown, a submersible pump cable anti-friction fixing device includes a lifting chain 2 and a cable 3 installed on the upper part of the submersible pump 1. Multiple sets of equally spaced connecting rods 4 are arranged between the lifting chain 2 and the cable 3. A mounting base 5 is installed at the end of the connecting rod 4 near the cable 3. A fixed clamping plate 6 and a movable clamping plate 7 are installed on the mounting base 5. Both the fixed clamping plate 6 and the movable clamping plate 7 are arc-shaped, and the end of the movable clamping plate 7 near the mounting base 5 is rotatably connected to the mounting base 5. A protective sleeve 9 for connecting the cable 3 is installed between the fixed clamping plate 6 and the movable clamping plate 7. An L-shaped fixing plate 12 corresponding to the movable clamping plate 7 is installed on the end of the fixed clamping plate 6 away from the mounting base 5. A fastening bolt 13 is threaded on the L-shaped fixing plate 12. One end of the fastening bolt 13 passes through the L-shaped fixing plate 12 and is fitted with a fastening block 14 corresponding to the movable clamping plate 7. The fastening block 14 is in contact with the side of the movable clamping plate 7 away from the protective sleeve 9.

[0019] By setting up multiple sets of fixed clamping plates 6 and movable clamping plates 7 on the mounting base 5, which cooperate with the protective sleeve 9, the cable 3 can be fixedly clamped at equal distances. The connecting rod 4 and the mounting base 5 cooperate to ensure that there is a certain distance between the lifting chain 2 and the cable 3, so as to avoid relative friction and compression between the lifting chain 2 and the cable 3. At the same time, the protective sleeve 9 protects the cable 3, effectively extending the service life of the cable 3 and ensuring the stability of the submersible pump 1.

[0020] The L-shaped fixed plate 12 has a slot 8 corresponding to the movable clamping plate 7. The width of the slot 8 is greater than the width of the movable clamping plate 7. The movable clamping plate 7 is pushed by the fastening bolt 13 and threadedly connected to the L-shaped fixed plate 12 through the fastening block 14 to squeeze the protective sleeve 9 and the cable 3, so that the cable 3 and the protective sleeve 9 are stably connected, ensuring the protective effect of the protective sleeve 9 on the cable 3. The slot 8 can meet the flexibility of the movable clamping plate 7 when the fastening block 14 pushes the movable clamping plate 7 to rotate, and avoid interference between the arc-shaped movable clamping plate 7 and the L-shaped fixed plate 12. The rotatable movable clamping plate 7, together with the fastening bolt 13 and the fastening block 14, can clamp and fix cables 3 of different sizes, meeting the applicability of the equipment.

[0021] The protective sleeve 9 is a rubber sleeve. The middle part of the protective sleeve 9 is provided with a cable placement groove 10 corresponding to the cable 3. An opening groove 11 connected to the cable placement groove 10 is opened on one side of the protective sleeve 9. By setting the protective sleeve 9 to be a rubber sleeve, the cable 3 can be further protected. By setting the opening groove 11, it is easy to put the protective sleeve 9 into the cable placement groove 10 from the side of the cable 3, thereby improving the convenience of installation of the protective sleeve 9 and the cable 3.

[0022] A further technical solution is that the outer side of the protective sleeve 9 is provided with anti-slip textures corresponding to the fixed clamping plate 6 and the movable clamping plate 7. By providing anti-slip textures on the outer side of the protective sleeve 9, the friction between the protective sleeve 9 and the fixed clamping plate 6 and the movable clamping plate 7 can be increased, thereby further improving the stability of the clamping between the fixed clamping plate 6, the movable clamping plate 7 and the protective sleeve 9.

[0023] Wear-resistant layers are provided on the sides of the movable clamping plate 7 and the fastening block 14 that are close to each other. By providing wear-resistant layers on the movable clamping plate 7 and the fastening block 14, the wear resistance of the movable clamping plate 7 and the fastening block 14 can be improved when the fastening block 14 rotates with the fastening bolt 13 and rubs against the movable clamping plate 7, thereby improving the service life of the movable clamping plate 7 and the fastening block 14.

[0024] The working process of this utility model is as follows: When using this device to fix the lifting chain 2 and the cable 3, firstly, multiple sets of protective sleeves 9 are sequentially connected to the cable 3 through the opening slot 11, and the cable 3 is inserted into the cable placement slot 10 on the protective sleeve 9. Then, the movable clamp 7 of the mounting base 5 at one end of the connecting rod 4 on the lifting chain 2 is rotated open, and the protective sleeve 9 with the cable 3 is placed between the fixed clamp 6 and the movable clamp 7. Then, the fastening bolt 13 is rotated so that the fastening block 14 pushes the movable clamp 7 to squeeze the protective sleeve 9 and the cable 3, thereby fixing the protective sleeve 9 and the cable 3. The multiple sets of connecting rods 4 between the lifting chain 2 and the cable 3 are set at equal distances, so as to avoid relative friction and squeezing between the lifting chain 2 and the cable 3 during the lifting process of the submersible pump 1, and also to avoid the lifting chain 2 and the cable 3 from getting tangled together.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
