Description

Technical Field

[0001] This utility model relates to the field of sealing protection technology, specifically to an electric pump cable protection device. Background Technology

[0002] A submersible pump is a type of water pump in which both the pump body impeller and the motor driving the impeller are submerged in water. In existing technology, when a submersible pump is lowered into the water, it needs to be secured with a rope and then slowly submerged. However, when the submersible pump is lowered into the water, the rope and the cable may not be synchronized, causing the cable to be under tension. This could lead to tearing at the connection between the cable and the submersible pump, affecting the sealing effect of the cable.

[0003] A search revealed a Chinese patent publication dated February 11, 2025, with publication number CN222464131U, which describes a sealing and protection device for a submersible pump cable. The device generally includes: a submersible pump body; a connecting seat fixedly installed on the outer surface of the submersible pump body near the top; a cable body fixedly connected inside the connecting seat; and two fixing plates symmetrically fixedly installed on the outer surface of the submersible pump body near the top. A rotating rod is movably embedded in the outer surface of both fixing plates away from the submersible pump body.

[0004] While the aforementioned existing technical solutions can reduce the tensile force on the cable body and the connector, thereby preventing the cable body from tearing, the device requires the cable to be fixed during use. When the cable changes direction, it is prone to hard bending, and repeated use can easily cause the cable core to break, reducing the stability of the equipment. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an electric pump cable protection device to solve the problem mentioned in the background technology that when the cable changes direction, it is easy for the cable to bend hard, and repeated use can easily cause the cable core to break, reducing the stability of the equipment.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an electric pump cable protection device, comprising a pump body, including two movable plates, a lifting ring fixedly connected to the top of the pump body, a cable provided on the pump body, two cooperating fixed plates fixedly connected to the outer wall of the pump body, a rotating shaft rotatably connected to each of the two fixed plates, the two movable plates respectively connected to the ends of the two rotating shafts that are close to each other, a torsion spring provided between the two rotating shafts and the two fixed plates, a threaded rod threadedly connected to each of the two movable plates, an arc-shaped clamping plate cooperating with the cable rotatably connected to the ends of the two threaded rods that are close to each other, and a limit rod fixedly connected to the ends of the two arc-shaped clamping plates that are far apart from each other, the limit rod being slidably connected to the movable plate.

[0009] By adopting the above technical solution, when the equipment is in use, rotating the two threaded rods drives the two arc-shaped clamps to move, so that the two arc-shaped clamps cooperate to clamp and fix the cable. The limiting rod is used to limit the arc-shaped clamps to prevent them from rotating, thus facilitating the clamping of the cable by the arc-shaped clamps. When the cable bends upward, it drives the arc-shaped clamps and the movable plate to rotate, thereby buffering the bending of the cable and allowing the cable to bend at a more gentle angle. This prevents the cable from bending sharply when changing direction, reduces the probability of cable core breakage, and thus improves the stability of the equipment.

[0010] Optionally, an arc-shaped baffle is fixedly connected to the arc-shaped clamp.

[0011] By adopting the above technical solution, the arc-shaped baffle is used to guide the bending angle of the cable when it is bent, so that the cable rotates in an arc shape, thereby further reducing the probability of cable core breakage.

[0012] Optionally, anti-slip pads are provided on the inner walls of both of the arc-shaped clamps, with the inner walls of the anti-slip pads in close contact with the cable.

[0013] By adopting the above technical solution, the anti-slip pad is used to increase the friction between the arc-shaped clamp and the cable, and improve the fixing effect of the arc-shaped clamp on the cable, thereby achieving the purpose of improving the stability of the equipment.

[0014] Optionally, a sealing sleeve is fixedly connected to the outer wall of the pump body. The sealing sleeve is fitted onto the cable, and a sealing ring is provided on the inner side wall of the sealing sleeve. The inner side wall of the sealing ring is in close contact with the cable.

[0015] By adopting the above technical solution, the sealing sleeve and the sealing ring are used to improve the sealing between the cable and the pump body, thereby improving the stability of the equipment.

[0016] Optionally, a stop member is fixedly connected to the outer wall of the pump body. The stop member is located above the two fixed plates and cooperates with the two movable plates.

[0017] By adopting the above technical solution, the blocking component is used to block the two movable plates, thereby preventing the movable plates from rotating excessively, and thus preventing the arc-shaped clamp and cable from rotating excessively, which would cause the cable to bend excessively in the position of the anti-slip sleeve, thereby improving the service life of the cable and achieving the purpose of improving the stability of the equipment.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This electric pump cable protection device, during equipment use, rotates two threaded rods to move two arc-shaped clamps, causing the two arc-shaped clamps to cooperate and clamp and fix the cable. A limiting rod is used to limit the arc-shaped clamps, preventing them from rotating. This facilitates the clamping of the cable by the arc-shaped clamps. When the cable bends upwards, the arc-shaped clamps and the movable plate rotate, thus buffering the bend and allowing the cable to bend at a gentler angle. This prevents the cable from undergoing a hard bend when changing direction, reducing the probability of cable core breakage and improving equipment stability. Attached Figure Description

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] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-3 A power pump cable protection device includes a pump body 1, two movable plates 2, a lifting ring 3 fixedly connected to the top of the pump body 1, a cable 4 mounted on the pump body 1, two mating fixed plates 5 fixedly connected to the outer wall of the pump body 1, a rotating shaft 6 rotatably connected to each of the two fixed plates 5, the two movable plates 2 respectively connected to the near ends of the two rotating shafts 6, a torsion spring 7 between the two rotating shafts 6 and the two fixed plates 5, threaded rods 8 threadedly connected to each of the two movable plates 2, an arc-shaped clamping plate 9 mating with the cable 4 rotatably connected to the near ends of the two threaded rods 8, and a limit rod 10 fixedly connected to the far ends of the two arc-shaped clamping plates 9. The cable 4 is slidably connected to the movable plate 2. When the equipment is in use, rotating the two threaded rods 8 drives the two arc-shaped clamping plates 9 to move, so that the two arc-shaped clamping plates 9 cooperate to clamp and fix the cable 4. The limiting rod 10 is used to limit the arc-shaped clamping plates 9 to prevent them from rotating, so that the arc-shaped clamping plates 9 can clamp the cable 4. When the cable 4 bends upward, it drives the arc-shaped clamping plates 9 and the movable plate 2 to rotate, thereby buffering the bending of the cable 4 and making the cable 4 bend at a more gentle angle. This prevents the cable from bending hard when it changes direction, reduces the probability of cable core breakage, and thus improves the stability of the equipment.

[0029] Reference Figures 1-4 An arc-shaped baffle 11 is fixedly connected to the arc-shaped clamp 9. The arc-shaped baffle 11 is used to guide the bending angle of the cable 4 when the cable 4 is bent, so that the cable 4 rotates in an arc shape, thereby further reducing the probability of cable core breakage.

[0030] Reference Figure 1 and Figure 2 Anti-slip pads 12 are provided on the inner sidewalls of both arc-shaped clamps 9. The inner sidewalls of the anti-slip pads 12 are in close contact with the cable 4. The anti-slip pads 12 are used to increase the friction between the arc-shaped clamps 9 and the cable 4, and improve the fixing effect of the arc-shaped clamps 9 on the cable 4, thereby improving the stability of the equipment.

[0031] Reference Figure 4A sealing sleeve 13 is fixedly connected to the outer wall of the pump body 1. The sealing sleeve 13 is sleeved on the cable 4. A sealing ring 14 is provided on the inner side wall of the sealing sleeve 13. The inner side wall of the sealing ring 14 is in close contact with the cable 4. The sealing sleeve 13 and the sealing ring 14 cooperate to improve the sealing between the cable 4 and the pump body 1, thereby improving the stability of the equipment.

[0032] Reference Figure 1 and Figure 2 A stopper 15 is fixedly connected to the outer wall of the pump body 1. The stopper 15 is located above the two fixed plates 5. The stopper 15 cooperates with the two movable plates 2. The stopper 15 is used to stop the two movable plates 2, thereby preventing the movable plates 2 from rotating excessively, thereby preventing the arc-shaped clamp 9 and the cable 4 from rotating excessively, causing the cable 4 to be excessively bent in the position of the anti-slip sleeve, thereby improving the service life of the cable 4 and achieving the purpose of improving the stability of the equipment.

[0033] In summary, the working principle and process of this electric pump cable protection device are as follows: During use, rotating the two threaded rods 8 moves the two arc-shaped clamps 9, causing them to engage and clamp the cable 4. The limiting rod 10 limits the arc-shaped clamps 9, preventing them from rotating. This facilitates the clamping of the cable 4. When the cable 4 bends upwards, the arc-shaped clamps 9 and the movable plate 2 rotate, buffering the bend and allowing the cable 4 to bend at a gentler angle. This prevents the cable from bending sharply when changing direction, reducing the probability of cable core breakage and improving equipment stability. The arc-shaped baffle 11 is used to... When cable 4 is bent, the bending angle of cable 4 is guided so that cable 4 rotates in an arc shape, thereby further reducing the probability of cable core breakage. Anti-slip pad 12 is used to increase the friction between arc-shaped clamp 9 and cable 4, and improve the fixing effect of arc-shaped clamp 9 on cable 4, thereby improving the stability of the equipment. Sealing sleeve 13 cooperates with sealing ring 14 to improve the sealing between cable 4 and pump body 1, thereby improving the stability of the equipment. Stopping element 15 is used to stop the two movable plates 2, thereby preventing the movable plates 2 from rotating excessively, thereby preventing the arc-shaped clamp 9 and cable 4 from rotating excessively, causing cable 4 to bend excessively in the position of anti-slip sleeve, thereby improving the service life of cable 4 and improving the stability of the equipment.

[0034] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
