Description

Technical Field

[0001] This utility model relates to the field of sound insulation technology for Roots blowers, specifically to a quick-installation mechanism for a sound insulation cover for Roots blowers. Background Technology

[0002] Roots blowers are positive displacement blowers, consisting of impeller end faces and front and rear end covers. They operate on the principle of using two lobe-shaped rotors moving relative to each other within a cylinder to compress and transport gas. Roots blower soundproof enclosures are composed of multiple panels. Current Roots blower soundproof enclosures require a large number of bolts and nuts for installation, making installation time-consuming and labor-intensive, significantly increasing the workload for workers.

[0003] A search revealed a Chinese patent publication dated August 6, 2021, with publication number CN213899300U, for a quick-installation mechanism for a soundproof enclosure for a Roots blower. The mechanism is broadly described as including an installation assembly, a central assembly, and side assemblies. The central assembly is fixedly installed on the installation assembly. Two side assemblies are fixedly installed on the left and right sides of the central assembly, respectively. The installation assembly includes two vertical plates, the tops of which are fixedly connected via a top plate. A stabilizing block is fixedly connected to the bottom of the top plate. A connecting rod is movably connected to the rear of the stabilizing block, and a connecting block is fixedly connected to the rear end of the connecting rod.

[0004] While the aforementioned existing technical solutions do not require many bolts and nuts for installation, saving time and effort and greatly reducing the workload of workers, the device has a relatively complex structure and requires strict adherence to the installation sequence. This can easily lead to confusion in the installation order when inexperienced personnel attempt to install it, resulting in repeated disassembly and reassembly and reducing work efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a quick installation mechanism for a soundproof enclosure for Roots blowers, thereby solving the problem mentioned in the background art where inexperienced personnel easily confuse the installation sequence, leading to repeated disassembly and assembly and reduced work efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a quick installation mechanism for a soundproof enclosure for a Roots blower, comprising two side soundproof components, including a front soundproof component and a middle soundproof component. The two side soundproof components are respectively located on both sides of the middle soundproof component. The front soundproof component is located at the front end of the middle soundproof component and the two side soundproof components. The top of the front soundproof component and the two side soundproof components are provided with placement grooves. Two slots are provided on the inner sidewalls of the three placement grooves. The top of the middle soundproof component is rotatably connected to three rotating plates. Each of the three rotating plates is provided with a torsion spring between it and the middle soundproof component. The bottom of each of the three rotating plates is fixedly connected to a placement block. Each of the two ends of the three placement blocks is provided with a control groove. A plug rod that cooperates with the slot is slidably connected inside the control groove. A spring is provided between the plug rod and the control groove.

[0009] By adopting the above technical solution, the middle sound insulation component, the front sound insulation component, and the two side sound insulation components are fastened to the fan in their respective positions. At the same time as the insertion rod is pressed into the control slot, the torsion spring drives the rotating plate and the placement block to rotate, so that the placement block is inserted into the placement slot. At this time, the spring pushes the insertion rod to move, so that the insertion rod is inserted into the slot, thereby connecting the middle sound insulation component, the front sound insulation component, and the two side sound insulation components. This eliminates the need for the equipment to be installed in a strict order, avoids repeated disassembly and assembly, and achieves the purpose of improving work efficiency.

[0010] Optionally, two circular grooves are provided on both the front sound insulation component and the middle sound insulation component. Two fixed cylinders are fixedly connected to the outer walls of both side sound insulation components. A connecting rod is slidably connected inside the fixed cylinder. One end of the connecting rod is connected to a connecting plate. A circular rod that mates with the circular groove is fixedly connected to the connecting plate.

[0011] By adopting the above technical solution, pulling the connecting rod moves the connecting plate and the round rod, which moves the round rod away from the side sound insulation component, thus facilitating the connection between the front sound insulation component and the middle sound insulation component. At this time, pushing the connecting plate moves the round rod into the round groove, thereby strengthening and fixing the side sound insulation component and preventing it from tilting or rotating, thus improving the stability of the equipment.

[0012] Optionally, each of the four circular grooves has a slot on its inner sidewall, and each of the four circular rods has a clearance groove. Each of the four circular rods is rotatably connected to a rotating rod that communicates with the clearance groove. The clearance groove has a locking block inside that cooperates with the slot, and one end of the locking block is connected to the rotating rod.

[0013] By adopting the above technical solution, when the round rod is inserted into the round groove, rotating the rotating rod drives the locking block to rotate, so that one end of the locking block is inserted into the locking groove, thereby positioning the round rod and preventing the round rod from falling out of the round groove, thereby improving the stability of the equipment.

[0014] Optionally, the upper inner sidewall of the control groove is provided with a through groove, and a control block that passes through the through groove is fixedly connected to the insertion rod.

[0015] By adopting the above technical solution, the control block is used to facilitate personnel to control the insertion rod, thereby making it easier for personnel to control the insertion rod to retract into the control slot, and thus facilitating personnel to disassemble and assemble the equipment.

[0016] Optionally, a first sound insulation pad is fixedly connected to one end of the front sound insulation component, and a first blocking component that cooperates with the first sound insulation component is provided on the inner side wall of the middle sound insulation component and the two side sound insulation components. A second sound insulation pad is fixedly connected to the inner side wall of the middle sound insulation component, and a second blocking component that cooperates with the second sound insulation pad is provided on the inner side wall of the two side sound insulation components.

[0017] By adopting the above technical solution, the first sound insulation pad and the first blocking component work together to improve the sealing between the front sound insulation component and the middle sound insulation component and the side sound insulation component. The second sound insulation pad and the second blocking component work together to improve the sealing between the middle sound insulation component and the side sound insulation component, thereby achieving the purpose of improving the sound insulation effect of the equipment.

[0018] Optionally, the front sound insulation component has two first positioning blocks fixedly connected to one end near the middle sound insulation component, and both side sound insulation components have two second positioning blocks fixedly connected to one end near the middle sound insulation component. The middle sound insulation component has positioning slots that cooperate with the first and second positioning blocks.

[0019] By adopting the above technical solution, the first positioning block cooperates with the positioning slot to perform preliminary positioning of the front sound insulation component and the middle sound insulation component during installation, and the second positioning block cooperates with the positioning slot to perform preliminary positioning of the side sound insulation component and the middle sound insulation component during installation. This facilitates the installation and connection of the equipment by personnel, thereby improving work efficiency.

[0020] (III) Beneficial Effects

[0021] In summary, this utility model has at least one of the following beneficial technical effects:

[0022] This quick-installation mechanism for the soundproof enclosure of a Roots blower involves attaching the central soundproof component, front soundproof component, and two side soundproof components to the blower in their respective positions. Simultaneously, pressing the insertion rod into the control slot causes the torsion spring to rotate the rotating plate and placement block, allowing the placement block to insert into the placement slot. At this point, the spring pushes the insertion rod to move, inserting it into the slot. This connects the central soundproof component, front soundproof component, and two side soundproof components, eliminating the need for strict sequential installation and avoiding repeated disassembly and assembly, thus improving work efficiency.
