Description

Technical Field

[0001] This utility model relates to the technical field of vibration damping structure for submersible pumps, specifically a vibration damping structure for a submersible pump used in coal mine electromechanical applications. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are usually dug underground to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is usually stripped away to extract the coal; this is called an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. During the mining process of underground coal mines, a large amount of groundwater is often encountered. In order to facilitate the normal mining of coal, water pumps are needed to extract this water.

[0003] A submersible pump for coal mine electromechanical applications, with publication number CN212838413U, includes a motor and a pump body. The pump body is fixed inside a filter cover, and the bottom of the filter cover is connected to a support via multiple connecting components. Four symmetrically arranged shock-absorbing legs are provided on the lower surface of the support. Both the filter cover and the support have multiple filter holes. The filter cover has a spherical structure, including a hemispherical filter cover A and a filter cover B. This invention has a simple structure, is easy to disassemble, is safe and stable, and is not easily clogged, making it suitable as a replacement for existing submersible pumps for coal mine electromechanical applications. However, the aforementioned submersible pump for coal mine electromechanical applications, due to its simple structure and lack of a shock-absorbing structure, results in excessive noise during operation and is easily damaged by bumps during transportation and movement. Therefore, it is necessary to provide a new shock-absorbing structure for submersible pumps for coal mine electromechanical applications to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a shock-absorbing structure for a submersible pump used in coal mine electromechanical applications, which has the advantages of shock absorption and improved protection, and external protection to improve the stability of use, thus solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping structure for a submersible pump used in coal mine electromechanical applications, comprising: a base, with a pump body fixedly connected to the top of the base, and a connecting seat fixedly connected to the outside of the pump body; a vibration damping component, comprising two damping rods, both of which are fixedly connected to the bottom of the base; and a protective component, comprising a steel mesh, which is fitted over the outside of the pump body. The damping rods and pump body used in this application are commercially available products, and their principles, connection methods, and control methods are well-known to those skilled in the art, and therefore will not be elaborated upon here. In use, the device is first installed in a suitable position, and the two damping rods utilize the physical effect of damping. When an object is subjected to external force, due to factors such as viscosity, friction, and deformation of the medium, vibration energy is gradually converted into heat energy. Combined with a buffer spring, this reduces the vibration amplitude. After installation, during daily use, the protective frame prevents falling debris from directly impacting the pump body, improving the overall protection of the pump body and enhancing the durability and stability of the entire device during use.

[0006] Preferably, the shock absorption assembly further includes a fixing frame, which is sleeved on the outside of the base. A base plate is fixedly connected to the bottom of the fixing frame. Both damping rods are fitted with buffer springs. Based on the physical effect of damping, when an object is subjected to external force, due to factors such as the viscosity, friction, and deformation of the medium, the vibration energy is gradually converted into heat energy. Using buffer springs can reduce the vibration amplitude.

[0007] Preferably, the base plate has four threaded holes inside, and screws are rotatably connected to the threads inside the threaded holes. The screws can be rotatably connected to the threaded holes inside the base plate, which can realize the fixed installation of the base plate and improve the stability of the overall device during installation.

[0008] Preferably, each of the four screws is fitted with a limiting spring. The limiting spring is made of stainless steel and its elastic force can act in the opposite direction on the screw, so that the screw will not easily loosen after being tightened.

[0009] Preferably, the protective component further includes a sleeve, which is uniformly and fixedly connected to the top of the steel mesh. A sliding rod is slidably connected inside the sleeve, and a protective frame is fixedly connected to the top of the sliding rod. The protective frame can prevent external falling gravel from directly hitting the pump body, thereby improving the overall protection effect of the pump body and enhancing the durability and stability of the overall device during use.

[0010] Preferably, a return spring is fixedly connected to the bottom of the slide rod. The return spring is sleeved inside the sleeve. The elastic force of the return spring can help the protective frame to buffer and release force when an external force hits the protective frame, which can greatly reduce the impact of the impact force directly on the pump body and improve the protection of the pump body.

[0011] Preferably, rubber strips are uniformly fixedly connected to the top of the protective frame. The rubber strips can assist the protective frame in playing a protective role, so that when external force comes into contact with the protective frame, the rubber strips can dissipate the impact force.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] I. When using this utility model, first install the device in a suitable position, and then use two damping rods based on the physical effect of damping. When an object is subjected to external force, due to factors such as viscosity, friction and deformation of the medium, the vibration energy will gradually be converted into heat energy. When used in conjunction with a buffer spring, the vibration amplitude can be reduced.

[0014] Second, after installation, this utility model can prevent falling stones from directly hitting the pump body during daily use, thus improving the overall protection of the pump body and enhancing the durability and stability of the entire device during use. Attached Figure Description

When using the device, it is first installed in a suitable position, and the two damping rods 9 are used based on the physical effect of damping. When an object is subjected to external force, due to factors such as viscosity, friction and deformation of the medium, vibration energy will gradually be converted into heat energy. When used with buffer spring 10, the vibration amplitude can be reduced. After installation, during daily use, the protective frame 12 can prevent external falling gravel from directly hitting the pump body 1, improving the overall protection effect of the pump body 1 and improving the durability and stability of the overall device during use.

[0022] The vibration damping assembly also includes a fixed frame 5, which is fitted onto the outside of the base 4. A base plate 6 is fixedly connected to the bottom of the fixed frame 5. Buffer springs 10 are fitted onto the outside of each of the two damping rods 9. Based on the physical effect of damping, when an object is subjected to external force, due to factors such as viscosity, friction, and deformation of the medium, the vibration energy is gradually converted into heat energy. The use of buffer springs 10 can reduce the vibration amplitude.

[0023] The base plate 6 has four threaded holes inside, and screws 7 are rotatably connected to the threads inside the threaded holes. The screws 7 can be rotatably connected to the threaded holes inside the base plate 6, which can realize the fixed installation of the base plate 6 and improve the stability of the overall device during installation.
