Technical Field

[0001] This utility model belongs to the field of deep well pump technology, and specifically refers to a new type of deep well pump structure. Background Technology

[0002] The most distinctive feature of deep well pumps is that the motor and pump are connected together. They are pumps that are submerged in underground wells to draw and transport water, and are widely used in agricultural irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Traditional deep well pumps have their power cord directly connected to the motor, located between the motor and the pump body. In practice, power cord damage is frequent. Replacing the power cord requires disassembling the pump body and motor, making the process cumbersome. Furthermore, the common method for securing the power cord is to use a fixing strip to secure it to the pump body, further complicating the power cord replacement process. Summary of the Invention

The connecting frame is located at the water inlet end of the pump body, and a filter screen is provided on the outside of the connecting frame. The power cord extends along the outside of the motor toward the connecting frame through a protective structure.

[0006] In the aforementioned novel deep well pump structure, the protective structure includes a protective cover and at least two fixing members. The fixing members are located on the protective cover and are fixed to the motor and connecting frame by locking members. The power cord is located inside the protective cover.

[0008] In the above-mentioned novel deep well pump structure, the bottom of the motor is provided with several support feet, the power cord is located between two adjacent support feet, and the power cord is covered with a protective sleeve.

[0009] In the above-mentioned novel deep well pump structure, the filter screen is provided with a lug on the side facing the motor, and the connecting frame is provided with a groove that cooperates with the lug.

[0010] In the above-mentioned novel deep well pump structure, the filter screen has a receiving notch on the side facing the pump body, and a second protective sleeve is fitted on the power line, with the second protective sleeve located at the receiving notch.

[0011] In the above-mentioned new deep well pump structure, two locking grooves are respectively provided at both ends of the filter screen, and the connecting frame is provided with fixing holes that cooperate with the locking grooves.

[0012] In the aforementioned novel deep well pump structure, the connecting frame includes an upper connecting ring, a lower connecting ring, and a support column, with the upper connecting ring and the lower connecting ring connected to each other via the support column.

[0013] In the above-mentioned novel deep well pump structure, the pump body is fixedly connected to the upper connecting ring, and the motor is detachably connected to the lower connecting ring.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] This invention places the power cord at the bottom of the motor and protects it with a protective structure. This way, even if the power cord is damaged, there is no need to disassemble the pump body; only the protective structure needs to be removed, making the operation simple and convenient.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments:

[0024] like Figures 1-5 As shown: A novel deep well pump structure includes a motor 1, a pump body 2, and a connecting frame 3. The motor 1 is connected to the pump body 2 via the connecting frame 3, and the power cord of the motor 1 is located at the bottom of the motor 1 and away from the pump body 2. The connecting frame 3 is located at the water inlet end of the pump body 2, and a filter screen 4 is provided on the outside of the connecting frame 3. The power cord extends along the outside of the motor 1 toward the connecting frame 3 through a protective structure 5. By placing the power cord at the bottom of the motor and protecting it with a protective structure, this invention eliminates the need to disassemble the pump body even if the power cord is damaged; only the protective structure needs to be removed, making operation simple and convenient.

[0025] In the above-mentioned novel deep well pump structure, the protective structure 5 includes a protective cover 51 and at least two fixing members 52. The fixing members 52 are located on the protective cover 51 and are fixed to the motor 1 and the connecting frame 3 by locking members. The power cord is located inside the protective cover 51. Specifically, this utility model uses two fixing members, and the fixing members are located at both ends of the protective cover. The locking member is a bolt, which passes through the fixing member to fix the fixing member and the protective cover to the motor and the connecting frame.

[0026] In the aforementioned novel deep well pump structure, the protective cover 51 has a U-shaped structure, specifically, the power cord is located within the groove of the protective cover.

[0027] In the above-mentioned new deep well pump structure, the bottom of the motor 1 is provided with several support feet 11, the power cord is located between two adjacent support feet 11, and the power cord is covered with a protective sleeve 12. Specifically, the designed support feet can prevent the motor from directly contacting the bottom of the water source, and the designed protective sleeve is made of rubber or silicone material, which can prevent damage to the connection and bend, and extend the service life of the power cord.

[0028] In the aforementioned novel deep well pump structure, the filter screen 4 has a lug 41 on the side facing the motor 1, the connecting frame 3 has a groove 42 that cooperates with the lug 41, the filter screen 4 has a receiving notch 43 on the side facing the pump body 2, and a protective sleeve 44 is fitted on the power cord. The protective sleeve 44 is located at the receiving notch 43. Specifically, the lug and groove are designed to facilitate the positioning of the filter screen and prevent it from rotating. The protective sleeve 44 is designed to prevent the power cord from directly contacting the receiving notch of the filter screen, thus avoiding damage to the power cord and extending its service life.

[0029] In the above-mentioned new deep well pump structure, the filter screen 4 is provided with two locking grooves 45 at both ends, and the connecting frame 3 is provided with fixing holes 46 that cooperate with the locking grooves 45.
