[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a flexible, soft-connection, noiseless screw pump mechanism, which has the following advantages:

[0018] 1. This flexible, soft-connection, noiseless screw pump mechanism, through the inclusion of a pressure display mechanism, an air extraction mechanism, and a top cover mechanism, addresses the issue of internal air turbulence during screw pump operation. Turbulence can cause air molecules to collide and rub against each other, generating noise. The air extraction mechanism promptly removes some air, reducing air accumulation and turbulence within the casing, thus lowering noise levels caused by air turbulence. Air extraction also regulates the internal air pressure, maintaining it within a suitable range. Appropriate air pressure helps reduce vibrations caused by pressure imbalances during screw pump operation, as negative pressure causes sound waves to encounter different pressure gradients during propagation, leading to sound energy loss and reducing noise propagation intensity. The sealing cover and sealing plate design ensure a good seal on the top of the casing, effectively preventing internal noise from propagating to the external environment. The sealing plate adheres to the sound insulation plate, further enhancing the overall sound insulation effect of the mechanism and achieving the purpose of incorporating a sound-absorbing structure.

[0019] 2. This flexible, noiseless screw pump mechanism, through the setting of a top cover mechanism and an installation mechanism, locates the pressure plates on the mounting boxes on the left and right sides of the outer casing. Press the pressure plates on both sides simultaneously and evenly with both hands, causing the crossbar to slide into the mounting box, compressing the fixing spring and moving the vertical plate. The movement of the vertical plate causes the triangular block on it to move as well, separating the triangular block from the wedge plate, releasing the restriction on the wedge plate, and then the sealing cover and sealing plate can be removed, achieving the purpose of convenient disassembly of the noise-absorbing shell.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-8 The present invention provides a technical solution: a flexible soft-connection noiseless screw pump mechanism, including an outer casing 1, a sound insulation plate 8 movably installed on the inner side wall of the outer casing 1, a screw pump assembly 2 extending to its left side provided on the inner side of the outer casing 1, a support leg 7 fixedly installed on the bottom of the outer casing 1, a pressure display mechanism 3 extending to its inner side and penetrating the sound insulation plate 8 provided on the front side of the outer casing 1, an air extraction mechanism 4 extending to its inner side and penetrating the sound insulation plate 8 provided on the front side of the outer casing 1, a top cover mechanism 5 extending to its inner side provided on the top of the outer casing 1, and an installation mechanism 6 connected to the outer side of the outer casing 1 provided on the top of the top cover mechanism 5.

[0031] The outer casing 1 serves as the protective shell for the entire structure, isolating the internal components from the external environment and preventing dust and liquid intrusion. It also provides a mounting base for the sound insulation panel 8, pressure display mechanism 3, etc. The inner wall has mounting holes and through holes to facilitate the passage of components such as pump body 207 and connecting pipe 31. The top opening design, together with the top cover mechanism 5, achieves sealing and quick opening. The support legs 7 support the outer casing 1, keeping the equipment running stably and preventing vibration from being transmitted to the ground or resonating with other equipment. They are distributed at the four corners of the bottom of the outer casing 1 to distribute the weight of the equipment and reduce local stress. The sound insulation panel 8 blocks the airborne noise generated by components such as pump body 207 and drive motor 201 during operation, forming a double-layer sound insulation structure with the inner wall of the outer casing 1 to further improve the noise reduction effect. High-density foam, glass wool, or polyester fiber sound-absorbing panels are covered with a protective film for moisture protection and are aligned with components such as pump body 207 and connecting pipe 31 to ensure a balance between functionality and sealing.

[0032] The screw pump assembly 2 includes a drive motor 201. The drive motor 201 is fixedly installed on the inner bottom wall of the outer casing 1. A support seat 202 located on the left side of the drive motor 201 is fixedly installed on the inner bottom wall of the outer casing 1. A connecting shaft 203 passing through the support seat 202 is fixedly installed at the output shaft of the drive motor 201. A first connecting member 204 is movably installed on the left side of the connecting shaft 203. A flexible connecting member 205 is movably installed on the left side of the first connecting member 204. A second connecting member 206 is movably installed on the left side of the flexible connecting member 205. A pump body 207 passing through the sound insulation plate 8 and extending to the left side of the outer casing 1 is movably installed on the left side of the second connecting member 206. A mounting bracket 208 sleeved on the outside of the pump body 207 is fixedly installed on the inner bottom wall of the outer casing 1. An inlet pipe 209 extending to the top of the outer casing 1 is fixedly installed at the input end of the pump body 207. An outlet pipe 210 located on the outside of the outer casing 1 is fixedly installed at the output end of the pump body 207.

[0033] The inner wall of the outer casing 1 has a mounting hole on the left side that matches the pump body 207, the inner side of the sound insulation plate 8 has a mounting hole that matches the pump body 207, and the inner side of the support base 202 has a mounting hole that matches the connecting shaft 203.

[0034] The drive motor 201 provides rotational power to drive the screw pump. It is fixed to the inner bottom wall of the outer casing 1 and transmits torque through the connecting shaft 203. The support base 202 supports the connecting shaft 203, reducing the radial load on the motor output shaft and preventing the motor shaft from bending due to the resistance of the pump body 207. An inner mounting hole is provided to allow for a clearance fit with the connecting shaft 203, permitting slight axial displacement. The connecting shaft 203 connects the drive motor 201 to the first connecting member 204, transmitting rotational motion. It passes through the support base 202, and friction is reduced through bearings or bushings. The first connecting member 204 and the second connecting member 206 fix the two ends of the flexible connecting member 205, achieving power transmission and flexible isolation. A flange structure is used to facilitate the disassembly and replacement of the flexible connecting member 205. The flexible connecting member 205 absorbs the vibration generated by the drive motor 201 during operation, preventing direct transmission to the pump body 207. It reduces airborne noise through a damping effect, allowing the pump body 207 and motor to maintain proper airflow due to thermal expansion and contraction or vibration. To minimize axial or radial displacement, rubber bellows, metal spring couplings, or polymer composite materials are used, balancing flexibility and durability. The design is optimized based on motor power and pump body resistance to avoid excessive deformation. Pump body 207 is the core component of the screw pump. The rotating screw draws fluid from the inlet pipe 209 and delivers it to the outlet pipe 210, penetrating the left side wall of the outer casing 1 and the sound insulation plate 8. It is fixed by mounting bracket 208 and connected to the second connector 206 via splines or flat keys to ensure torque transmission. Mounting bracket 208 fixes pump body 207, preventing displacement due to fluid reaction force or vibration. It is fitted onto the outside of pump body 207 and bolted to the inner bottom wall of outer casing 1. Inlet pipe 209 connects to an external fluid source (such as a water tank or pipe), introducing fluid into pump body 207. Outlet pipe 210 discharges the fluid output from pump body 207 to the target location. Inlet pipe 209 penetrates the sealing cover 51 and sealing plate 52. Outlet pipe 210 is located outside outer casing 1 to avoid interference with internal components.

[0035] The pressure display mechanism 3 includes a connecting pipe 31. The connecting pipe 31, which extends to the inside of the outer casing 1 and passes through the sound insulation plate 8, is movably installed on the front side of the outer casing 1. A pressure display instrument 32 is movably installed at one end of the top of the connecting pipe 31.

[0036] The connecting pipe 31 transmits the internal pressure of the pump body 207 to the pressure display instrument 32, avoiding direct contact between the instrument and the fluid. The pressure-resistant pipe (such as stainless steel or high-pressure rubber) is connected at both ends by threads or quick-connect fittings. The pressure display instrument 32 displays the delivery pressure in real time, which is convenient for monitoring the system operation status (such as blockage or leakage). It has an alarm function and can set upper and lower pressure thresholds.

[0037] The air extraction mechanism 4 includes a mounting frame 41. The mounting frame 41 located on the right side of the connecting pipe 31 is fixedly installed on the front side of the outer casing 1. An air extraction pump 42 extending to the top of the mounting frame 41 is movably installed on the inner side of the mounting frame 41. An air extraction pipe 43 extending to the inner side of the outer casing 1 and penetrating the sound insulation panel 8 is fixedly installed at the air inlet end of the air extraction pump 42.

[0038] Both the front inner wall of the outer casing 1 and the inner side of the sound insulation plate 8 are provided with through holes that are compatible with the connecting pipe 31. The top of the mounting frame 41 is provided with a mounting groove. Both the front inner wall of the outer casing 1 and the inner side of the sound insulation plate 8 are provided with through holes that are compatible with the exhaust pipe 43.

[0039] The mounting frame 41 fixes the air pump 42 and provides a mounting base. The top has a mounting slot to facilitate the disassembly and maintenance of the air pump 42. The air pump 42 and the air extraction pipe 43 extract the air inside the outer casing 1 to form a negative pressure environment, which further suppresses airborne noise (suitable for ultra-low noise scenarios). The air extraction pipe 43 passes through the sound insulation plate 8 and its end is close to the pump body 207 for efficient air extraction.

[0040] The top cover mechanism 5 includes a sealing cover 51. The sealing cover 51 is movably installed on the top outer side of the outer casing 1. A sealing plate 52 that fits against the sound insulation plate 8 is fixedly installed on the inner top wall of the sealing cover 51. One end of the water inlet pipe 209 passes through the sealing plate 52 and extends to the top of the sealing cover 51.

[0041] Both the sealing cover 51 and the sealing plate 52 have through holes on their inner sides that are compatible with the water inlet pipe 209, and there are four support legs 7.

[0042] The sealing cover 51 and the sealing plate 52 seal the top opening of the outer casing 1 to prevent noise from leaking from the top. The sealing plate 52 is attached to the sound insulation plate 8 to form a continuous sound insulation barrier, allowing the water inlet pipe 209 to pass through. At the same time, leakage is prevented by the rubber sealing ring. Metal (such as stainless steel) or high-strength plastic is used to ensure structural rigidity.

[0043] The mounting mechanism 6 includes a mounting box 61. Mounting boxes 61 are fixedly mounted on both the left and right sides of the outer casing 1. A vertical plate 62 extending to the top of the mounting box 61 is slidably mounted on the inner side of the mounting box 61. A triangular block 63 is fixedly mounted on one side of the vertical plate 62. Two horizontal bars 64 extending to the outside of the mounting box 61 are fixedly mounted on one side of the vertical plate 62. A fixing spring 65, which is fixedly connected to the inner wall of the mounting box 61 and sleeved on the outside of the horizontal bars 64, is fixedly mounted on one side of the vertical plate 62. A pressure plate 66 is fixedly mounted between one end of the two horizontal bars 64. Mounting plates 67 are fixedly mounted on both the left and right ends of the top of the sealing cover 51. A wedge-shaped plate 68 extending above the mounting box 61 and fitting against the bottom of the triangular block 63 is fixedly mounted on one side of the mounting plate 67. A U-shaped plate 69 located outside the wedge-shaped plate 68 is fixedly mounted between the front and rear sides of the vertical plate 62.

[0044] The inner top wall of the mounting box 61 is open, the two mounting boxes 61 are symmetrically distributed from left to right, the top of the triangular block 63 is inclined, the bottom of the wedge plate 68 is inclined, and a rectangular hole that matches the crossbar 64 is opened on one side of the inner wall of the mounting box 61.

[0045] The mounting box 61 accommodates locking components such as the vertical plate 62 and the triangular block 63, and provides a sliding track. The inner top wall is open to facilitate the insertion of the wedge plate 68. A rectangular hole is opened on one side for the horizontal bar 64 to slide. The vertical plate 62 and the triangular block 63 lock the wedge plate 68 through the bevel engagement, realizing the quick fixation of the sealing cover 51. The top of the triangular block 63 is inclined, forming a self-locking structure with the bottom bevel of the wedge plate 68. The horizontal bar 64 and the fixing spring 65 connect the vertical plate 62 and the pressure plate 66. Locking and releasing are achieved by spring reset. The fixing spring 65 is sleeved on the outside of the horizontal bar 64 to provide stable elastic force. The pressure plate 66 needs to be manually pressed to drive the vertical plate 62 to compress the spring and unlock the sealing cover 51. The wedge plate 68 is fixed on the mounting plate 67 of the sealing cover 51. After being inserted into the U-shaped plate 69, it is locked by the triangular block 63. The U-shaped plate 69 restricts the insertion direction of the wedge plate 68 to prevent misalignment.

[0046] In use, place the outer casing 1 on a level surface using the support legs 7 to ensure stability. Install the screw pump assembly 2, and fix the drive motor 201 and support base 202 to the inner bottom wall of the outer casing 1. Install the connecting shaft 203, first connector 204, flexible connector 205, second connector 206, and pump body 207 in sequence, ensuring that the connecting shaft 203 is aligned with the mounting hole of the support base 202. Fix the mounting bracket 208 to support the pump body 207, and connect the water inlet pipe 20. 9 and water outlet pipe 210, fix sound insulation plate 8 to the inner side wall of outer box 1, ensure that the circular hole and through hole are aligned with pump body 207, connecting pipe 31, etc., the connecting pipe 31 passes through the through hole of outer box 1 and sound insulation plate 8, connect pressure display instrument 32, cover sealing cover 51, water inlet pipe 209 passes through the through hole of sealing plate 52, use installation mechanism 6 to lock sealing cover 51, if air extraction and noise reduction are required, fix installation frame 41, connect air extraction pipe 43 to the inside of outer box 1, and start air extraction pump 42.

[0047] Confirm that the inlet pipe 209 and outlet pipe 210 are connected correctly and without leakage. Check if the pressure display 32 reading is normal (it should initially be zero or ambient pressure). Turn on the power to the drive motor 201 and observe whether the pump body 207 runs smoothly without abnormal vibration or noise. Monitor the delivery pressure through the pressure display 32 to ensure it is within the rated range. Start the air pump 42 to reduce the internal air pressure of the outer casing 1 to the target value (e.g., -30kPa) to further reduce noise. Regularly check: check whether the flexible connector 205 is aging or cracked and replace it in time. Clean the dust on the surface of the sound insulation board 8 to maintain the sound insulation effect. When not in use, first turn off the drive motor 201 and then stop the air pump 42. When opening the top cover mechanism 5, first press down the pressure plate 66 to release the lock, and then lift the sealing cover 51.

[0048] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0049] In summary, this flexible, noiseless screw pump mechanism, through the inclusion of a pressure display mechanism 3, an air extraction mechanism 4, and a top cover mechanism 5, addresses the issue of internal air turbulence during screw pump assembly 2 operation. Turbulence can cause air molecules to collide and rub against each other, generating noise. The air extraction mechanism 4 promptly removes some air, reducing air accumulation and turbulence within the casing, thus lowering noise caused by air turbulence. Air extraction also regulates the internal air pressure of the outer casing 1, maintaining it within a suitable range. Appropriate air pressure helps reduce vibration caused by pressure imbalance during screw pump assembly 2 operation, as negative pressure causes sound waves to encounter different pressure gradients during propagation, leading to sound wave energy loss and reducing noise propagation intensity. The design of the sealing cover 51 and sealing plate 52 ensures a good seal at the top of the outer casing 1, effectively preventing internal noise. Sound is transmitted to the external environment through the top. The sealing plate 52 fits with the sound insulation plate 8, further enhancing the sound insulation effect of the entire mechanism and achieving the purpose of having a sound-absorbing structure. By setting the top cover mechanism 5 and the installation mechanism 6, the pressure plates 66 on the mounting boxes 61 on the left and right sides of the outer box 1 are located. The pressure plates 66 on both sides are pressed evenly with both hands at the same time, causing the crossbar 64 to slide into the mounting box 61, compressing the fixing spring 65 and moving the vertical plate 62. The movement of the vertical plate 62 causes the triangular block 63 on it to move as well. The triangular block 63 separates from the wedge plate 68, releasing the restriction on the wedge plate 68. The sealing cover 51 and the sealing plate 52 can then be removed, achieving the purpose of convenient disassembly of the sound-absorbing shell. This solves the problem that the screw pump generates a lot of noise during use, and there is no corresponding sound-absorbing structure, which makes the use of the screw pump inconvenient. In addition, the sound-absorbing shell structure is fixed, making maintenance and disassembly extremely inconvenient.
