Description

Technical Field

[0001] The utility model relates to a submersible pump with an anti-dropping device, belonging to the technical field of submersible pump protection tools. Background Art

[0002] Submersible pumps are widely used for deep well water extraction. Usually, when people use submersible pumps, they will sink them into deep wells. After a long period of operation, the submersible pumps will inevitably age. Affected by factors such as blade wear, the drainage capacity of the submersible pumps gradually weakens, especially for multi-stage submersible pumps. Mud and foreign matter accumulate in the impeller compartment, blocking the submersible pumps, and the water pressure inside the pump body increases sharply, which in turn causes the pump body to rupture at the connection of the impeller compartment, and eventually causes the pump body's motor and the impeller compartment to break and separate, affecting water extraction;

[0003] More importantly, after the pump body breaks and separates in a deep well, the motor at the bottom cannot be dragged out through the water pipe, causing it to remain in the well. If the remaining motor is not removed in time, the well will be scrapped and the groundwater source will be polluted. However, the difficulty of deep well salvage is greatly increased.

[0008] Furthermore, a plurality of positioning grooves and fixing grooves are evenly arranged on the side of the bottom plate;

[0009] The bottom plate is fixed to the pump body in the circumferential direction by cooperating with the convex feet on the bottom surface of the pump body through the positioning groove;

[0010] A supporting rib is fixedly connected in the fixing groove.

[0011] Furthermore, an elastic pad for relieving impact is provided on the top of the gland, and the elastic pad is located between the gland and the bottom surface of the pump body.

[0012] Furthermore, a plurality of sealing grooves are evenly arranged on the outer wall of the gland, and the gland is movably sealed and connected to the compression chamber.

[0013] Furthermore, a plurality of support ribs are fixedly connected with reinforcement rings for enhancing their own structural strength.

[0026] like Figure 1-5 As shown, this embodiment is implemented by the following technical solution: a tray 1 for receiving the pump body 4 is provided at the bottom thereof, and the tray 1 is connected to a fixing plate 3 provided at the top of the pump body 4 through supporting ribs 2 .

[0027] The main body of the pump body 4 is enclosed in a cage structure composed of a tray 1 , support ribs 2 and a fixing plate 3 .

[0028] Specifically, the tray 1 includes: a bottom plate 101 , a compression chamber 102 is provided on the bottom plate 101 , a pressure cover 104 is movably connected in the compression chamber 102 , a spring 103 is provided at the bottom of the compression chamber 102 , and the spring 103 supports the pressure cover 104 to move up and down in the compression chamber 102 .

[0029] The tray 1 is also used to cushion the impact and extrusion force when the pump body 4 bulges and ruptures. The pressure acts on the gland 104. The spring 103 provides elastic buffering for the gland 104. The compression chamber 102 provides a buffer space for the gland 104 to prevent the pump body 4 from directly squeezing the support rib 2 when it bulges and deforms, causing the support rib 2 to rupture and tear.

[0030] Specifically, a plurality of positioning grooves 1011 and fixing grooves 1012 are evenly arranged on the side surface of the bottom plate 101 .

[0031] The bottom plate 101 is circumferentially fixed to the pump body 4 by cooperating with the protruding feet on the bottom surface of the pump body 4 through the positioning groove 1011 ; the support rib 2 is fixedly connected in the fixing groove 1012 .

[0032] Specifically, an elastic pad 1041 for alleviating impact is disposed on the top of the gland 104 , and the elastic pad 1041 is located between the gland 104 and the bottom surface of the pump body 4 .

[0033] Specifically, a plurality of sealing grooves 1042 are evenly arranged on the outer wall of the pressure cover 104 , and the pressure cover 104 and the compression chamber 102 are movably sealed and connected.

[0034] Specifically, a reinforcing ring 201 is fixedly connected to the supporting rib 2 for enhancing the structural strength of the supporting rib 2 .

[0035] The specific working principle of this scheme is as follows:

[0036] In this embodiment, the pump body 4 is a multi-stage submersible pump; the tray 1 supports the pump body 4. When the pump body 4 ruptures and separates, the separated pump body 4 is directly retained in the cage structure composed of the tray 1, the support ribs 2 and the fixed plate 3. The operator can drag the pump body 4 and the device out of the deep well together through the water diversion pipe on the pump body 4, or when salvaging the pump body, the operator can grab and fix the device to take the pump body 4 out of the deep well together.

[0037] Of course, the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and any equivalent changes and improvements made by ordinary technicians in the technical field within the essential scope of the present invention shall fall within the scope of the patent coverage of the present invention.
