Description

Technical Field

[0001] The utility model relates to the technical field of screw pumps, in particular to a protective structure for screw pumps. Background Art

[0002] The screw pump is a commonly used positive displacement pump used to transport various liquid media, including high-viscosity liquids, high-temperature liquids, corrosive liquids, etc. Its working principle is based on the rotating screw generating a spiral cavity in the pump body, and the liquid is pushed from the pump inlet along the spiral cavity to the outlet through the rotation of the screw. Screw pumps usually need to be equipped with protective structures to ensure the safe operation of the equipment and the safety of the operator.

[0003] In the traditional screw pump protection structure, the screw pump housing is usually made of strong and durable metal materials to protect the internal mechanical parts from the impact and damage of the external environment. The housing also has the functions of waterproof, dustproof and corrosion-resistant. A safety shield is set around the working area of ​​the screw pump to prevent the operator from accidentally contacting the rotating screw or other moving parts, thereby reducing the possibility of accidents. These shields are usually made of strong metal or plastic materials with good wear resistance and corrosion resistance.

[0004] However, the protective plate structure used in the protective structure of traditional screw pumps often only uses a single protective plate on the side of the pump body. The protective effect of this single protective plate is limited. If a person accidentally touches the protective plate, there may still be damage to the human body or the pump body, which reduces the protection of this protective structure to the safe operation of the equipment and the safety of the operator. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a protective structure for a screw pump, which aims to improve the protective plate structure used in the traditional screw pump protective structure which often only uses a single protective plate on the side of the pump body. The protective effect of this single protective plate is limited, and if a person accidentally touches the protective plate, there may still be damage to the human body or the pump body.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a protective structure for a screw pump, including a pump body, a base fixedly connected to the bottom of the pump body, a plurality of protective plates fixedly connected to the side walls of the base, a hydraulic rod fixedly connected to the bottom of the protective plate, a push plate fixedly connected to the output end of the hydraulic rod, a connecting column fixedly connected to the side wall of the push plate, a sliding column slidably connected to the inside of the connecting column, an anti-collision plate fixedly connected to one end of the sliding column, a slide table fixedly connected to the bottom of the protective plate, a slide groove provided inside the slide table, the top of the slide column is slidably connected to the inside of the slide groove, and a connecting component is provided on the top of the protective plate.

[0008] Furthermore, a motor is fixedly connected to the top of the connecting platform, and a connecting rod 1 is fixedly connected to the output end of the motor.

[0009] Furthermore, one end of the connecting rod one is rotatably connected to the connecting rod two, and one end of the connecting rod two is rotatably connected to the slider one.

[0010] Furthermore, a support platform is fixedly connected to the top of the connecting platform, and the sliding block is slidably connected inside the support platform.

[0011] Furthermore, a special-shaped groove is provided inside the support platform, and a bottom of the sliding block is slidably connected inside the support platform.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a protective structure for a screw pump, including a pump body 1, a base 2 is fixedly connected to the bottom of the pump body 1, a plurality of protective plates 3 are fixedly connected to the side wall of the base 2, a hydraulic rod 4 is fixedly connected to the bottom of the protective plate 3, a push plate 5 is fixedly connected to the output end of the hydraulic rod 4, a connecting column 6 is fixedly connected to the side wall of the push plate 5, a sliding column 7 is slidably connected inside the connecting column 6, an anti-collision plate 10 is fixedly connected to one end of the sliding column 7, a slide table 8 is fixedly connected to the bottom of the protective plate 3, a slide groove 9 is opened inside the slide table 8, the top of the slide column 7 is slidably connected inside the slide groove 9, and a connecting component is arranged on the top of the protective plate 3.

[0024] Specifically, the hydraulic rod 4 generates a pushing and pulling force, which acts on the push plate 5, causing it to displace at the bottom of the protective plate 3. The displacement of the push plate 5 also drives the synchronous movement of its side wall connecting column 6 and the sliding column 7 inside the connecting column 6. When the connecting column 6 moves to the bottom of the slide 8, the sliding column 7 begins to slide inside the slide groove 9. As the sliding column 7 slides outward from the inside of the connecting column 6, the top of the anti-collision plate 10 begins to separate from the protective plate 3 and move outward. In this process, the action of the hydraulic rod 4 causes the pump body 1 to be covered with double protection, which greatly reduces the risk of accidents. This double protection design not only ensures the safe operation of the equipment, but also ensures the safety of the operator, effectively preventing the occurrence of accidental injuries.

[0025] Reference Figure 3The connecting component includes a connecting platform 11, and multiple connecting platforms 11 are fixedly connected to the top of each protective plate 3. A motor 14 is fixedly connected to the top of the connecting platform 11, and a connecting rod 15 is fixedly connected to the output end of the motor 14. One end of the connecting rod 15 is rotatably connected to a connecting rod 2 16, and one end of the connecting rod 2 16 is rotatably connected to a slider 17. The top of the connecting platform 11 is fixedly connected to a support platform 12, and a slider 17 is slidably connected to the inside of the support platform 12. A special-shaped groove 13 is opened inside the support platform 12, and the bottom of the slider 17 is slidably connected to the inside of the support platform 12. The top of the slider 17 is fixedly connected to a slide 18, and the top of the slide 18 is slidably connected to a slide 2 19, and the bottom of the slide 18 is slidably connected to the inside of the special-shaped groove 13, and the top of the slider 2 19 is fixedly connected to a lamp stand 20.

[0026] Specifically, the function of the motor 14 is to output a rotating force to the connecting rod 15, and this force drives the connecting rod 15 to rotate and change its own inclination angle. The movement of the connecting rod 15 then affects the connecting rod 2 16 at one end thereof, so that the connecting rod 2 16 also changes its inclination angle. This series of movements causes the entire structure to begin to change. The change in the inclination angle of the connecting rod 15 will pull the slider 17, so that the slider 17 begins to slide inside the support 12. During the movement of the slider 17, a part of the bottom of the slide 18 extends, and this part is constrained by the special-shaped groove 13, causing the slider 2 19 to begin to slide inside the slide 18. The movement of the slider 2 19 then drives the lamp stand 20 to pass through the trajectory of the special-shaped groove 13, and can quickly change the sliding trajectory. The structure designed in this way realizes the warning function. Through the movement of the lamp stand 20, the operator can be reminded of safety matters and can indicate the operating status of the pump. The existence of this warning system enables the operator to discover and solve problems in a timely manner, thereby ensuring the safety of the workplace.

[0027] Working principle: When it is necessary to protect the pump body 1, first start the hydraulic rod 4. The hydraulic rod 4 outputs a push-pull force to the push plate 5, which drives the push plate 5 to move at the bottom of the protective plate 3. When the push plate 5 moves, it drives the connecting column 6 on its side wall and the sliding column 7 inside the connecting column 6 to move synchronously. When the connecting column 6 moves to the bottom of the slide 8, the sliding column 7 will slide inside the slide groove 9, and the sliding column 7 will slide out from the inside of the connecting column 6. At this time, the anti-collision plate 10 can be pushed out to the outside of the protective plate 3, forming a double protection for the pump body 1, thereby reducing the possibility of accidents and ensuring the safe operation of the equipment and the safety of the operators. When it is necessary to warn the staff around the pump body 1, start the motor 14. The motor 14 outputs a rotating force to the connecting rod 15, which drives the connecting rod 15 to rotate and change its own inclination angle. The connecting rod 15 then drives the connecting rod 2 16 at one end thereof to also change its inclination angle. This process can pull the slider 17, so that the slider 17 slides inside the support 12. During the movement of the slider 17, the part of the slider 17 extending from the bottom of the slide 18 is constrained by the special-shaped groove 13, so that the slider 2 19 slides inside the slide 18 and then drives the lamp stand 20 to quickly change the sliding trajectory through the trajectory of the special-shaped groove 13. This structure realizes a warning function, prompts the operator to pay attention to safety matters and indicates the operating status of the pump, so as to timely discover and solve problems.
