Description

Technical Field

[0001] The utility model relates to a cable protection device, in particular to an underwater motor cable protection device. Background Art

[0002] In the sewage treatment industry, submersible pumps, propeller pumps and other underwater electromechanical devices are often used, and the cable lines in these electromechanical devices are also underwater for a long time. The water flow in the sewage treatment tank is very complex, and the water flow velocity will cause lateral force on the underwater cable, and both ends of the cable are easily damaged; in addition, it will also cause the cable to be longitudinally tensioned, causing the cable to crack, reducing the service life of the cable, and even affecting the operation of the motor, resulting in equipment failure. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide an underwater motor cable protection device, which can effectively protect the underwater cable and reduce the damage of the motor cable underwater.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] An underwater motor cable protection device includes a protection component and a fixing component;

[0006] The protection component includes a protection sleeve, and the protection sleeve is sleeved outside the underwater cable and sealed with the underwater cable through a sealant layer;

[0007] The fixing component includes a bracket, and quick-release clamps are fixed at the lower end of the bracket and the top edge of the sewage treatment tank, and the quick-release clamps hold the underwater cable tightly;

[0008] The quick-release clamp includes a mounting plate, both ends of the mounting plate are fixedly connected with the bracket, a left semi-circular pipe and a right semi-circular pipe are hinged at the middle position of the mounting plate, and the horizontal parts at the other ends of the left semi-circular pipe and the right semi-circular pipe face each other and are locked through an elastic clamping member.

[0009] The elastic clamping member includes a slotted hole provided on the left semi-circular pipe, a slotted hole provided on the right semi-circular pipe, a slotted groove is provided in the vertical direction at the upper end of the slotted hole, and one end of an elastic rod is hinged on the left semi-circular pipe, passes through the slotted hole and the slotted hole and abuts against the slotted groove.

[0010] The elastic rod includes a lower sleeve and an upper support rod, the lower part of the upper support rod is located in the lower sleeve and is sleeved with a spring, a limiting plate is provided at the bottom end of the upper support rod, and the spring is in a compressed state when locked.

[0011] The utility model provides an underwater motor cable protection device, which has the following technical effects:

[0012] 1). During the operation of the equipment, by setting up a protective sleeve, the collision between the cable and other underwater objects can be effectively reduced, and at the same time, the damage caused by the long-term scouring of the water flow to the underwater cable can be reduced, greatly improving the safety and reliability of the underwater motor cable.

[0013] 2). By setting up a quick-release clamp, the underwater cable can be tightly held up and down. In this way, the underwater cable is prevented from swinging due to lack of restraint, thereby avoiding the problem of cracking of the underwater cable caused by long-term swinging, and ultimately achieving the purpose of extending the service life of the underwater cable.

[0021] An underwater motor cable protection device includes a protection component and a fixing component.

[0022] As Figure 2 shown, the protection component includes a protection sleeve 3, and the protection sleeve 3 is made of UPVC steel wire hose waterproof and insulating material. The underwater cable 2 is sleeved in the protection sleeve 3, and a sealing glue layer 4 is provided between the underwater cable 2 and the protection sleeve 3. The protection sleeve 3 and the sealing glue layer 4 form a seal, which can prevent the cable from directly contacting the sewage, and can effectively extend the service life of the cable.

[0023] As Figure 1 shown, the fixing component includes a bracket 5, a guide wheel 6 is fixed at the upper end of the bracket 5, and the guide wheel 6 guides the underwater cable 2. A quick-release clamp 1 is fixed at the lower end of the bracket 5 and the top edge of the sewage treatment tank, and the quick-release clamp 1 can hold the underwater cable 2 tightly. Thus, the underwater cable 2 is effectively prevented from swinging with the movement of the water body, ensuring the safety and durability of the cable.

[0024] Specifically, Figures 3 - 5 As shown, the quick-release clamp 1 includes a mounting plate 1.1, which is fixedly connected to the bracket 5. A left semicircular tube 1.2 and a right semicircular tube 1.3 are provided on one side of the mounting plate 1.1. One end of the left semicircular tube 1.2 and the right semicircular tube 1.3 are rotatably connected to a pin fixed on the mounting plate 1.1 through a sleeve, and the horizontal parts 1.3.1 at the other ends of the left semicircular tube 1.2 and the right semicircular tube 1.3 are opposite and locked by a hinged elastic clip 1.4.

[0025] like Figure 6 As shown, the elastic clamp 1.4 includes an elastic rod 1.4.1 hinged on the left semicircular tube 1.2, a straight rod 1.4.2 is fixed on the upper part of the elastic rod 1.4.1, a slot 1.4.3 is provided on the left semicircular tube 1.2 for the elastic rod 1.4.1 and the straight rod 1.4.2 to pass through, a straight hole 1.4.4 is provided on the right semicircular tube 1.3 for the straight rod 1.4.2 to pass through, and a horizontal part 1.3.1 at the upper end of the right semicircular tube 1.3 opposite to the straight hole 1.4.4 is vertically provided with a straight groove 1.4.5.

[0026] The elastic rod 1.4.1 here includes a lower sleeve and an upper support rod, and the diameter of the lower sleeve and the upper support rod is smaller than the width of the straight rod 1.4.2. The upper support rod is located in the lower sleeve and is sleeved with a spring 1.4.6, which can push the upper support rod downward to retract the upper support rod part into the lower sleeve.

[0027] like Figure 6 As shown, the elastic clamp 1.4 is in a locked state and the spring 1.4.6 is in a compressed state. When unlocking is required, pull the straight rod 1.4.2 upwards, and the straight rod 1.4.2 is located above the horizontal portion 1.3.1 of the right semicircular tube 1.3, and the spring 1.4.6 continues to be compressed. Rotate the straight rod 1.4.2 about 90 degrees to keep the straight rod 1.4.2 parallel to the straight hole 1.4.4. After letting go, under the action of the spring 1.4.6, the upper support rod partly retracts into the lower sleeve, so that the straight rod 1.4.2 and the upper part of the upper support rod move downward to disengage from the horizontal portion 1.3.1 of the right semicircular tube 1.3, rotate the elastic clamp 1.4 outward, and then the right semicircular tube 1.3 can be opened to release the lock. When locking is required, the reverse operation can be performed.
