Description

Technical Field

[0001] The present application relates to the technical field of generator set silent equipment, and in particular to a generator set silent box. Background Art

[0002] Diesel generator sets have become the main backup power generation equipment in various industries due to their large output power and relatively stable performance. According to their actual application conditions, silent boxes specially used for the installation of diesel generator sets have been derived to achieve the purpose of noise reduction.

[0003] The traditional soundproof box for diesel generator sets is in the form of a box structure, with 1-2 doors and observation windows on the side of the box for operation or maintenance corresponding to the generator set. When installing the generator set in the soundproof box, it is usually necessary to place each device of the generator set in the soundproof box by hoisting from the top or one side, and then fix it; or the generator set is first installed on the bottom plate, and then the soundproof box is hoisted from the top and fixed to the bottom plate, which makes installation and maintenance inconvenient.

[0004] In order to solve the above problems, Chinese utility model patent CN202321036713.4 discloses an environmentally friendly soundproof box, which includes a bottom plate, which is slidably installed through slide grooves on the two side walls of the soundproof box. When installing the generator set, the bottom plate can be slid out of the soundproof box to one end. At this time, since the bottom plate is completely open, it can be more convenient to install the generator set. After the installation is completed, the bottom plate is sent into the soundproof box along the slide groove again. In order to save effort for the bottom plate to slide, a roller is also installed at the bottom of the slide groove to assist the bottom plate in entering and exiting. After the installation is completed, the top plate and the side plates can be fixed to the soundproof direction.

[0005] Although the mute box disclosed in the above patent document solves the problem of inconvenient installation of the generator set, it still has the following defects: the sliding installation of the slide roller shaft leads to high product processing and manufacturing costs, and there may be a hidden danger of jamming after long-term use. Therefore, the problem of inconvenient installation and maintenance of the generator set in the above mute box has not been well solved.

[0006] In addition, the traditional soundproof box is basically made of ordinary steel plates, and the outside of the box is sprayed with anti-rust paint. It will still rust if exposed to the outdoors for a long time, and the positive angle of the soundproof box is 90°, and the corner is sharp, which poses a safety hazard. Therefore, it is necessary to propose a new technical solution to solve the problems existing in the existing technology. Utility Model Content

[0035] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0036] In the description of this application: unless otherwise specified, "plurality" means two or more. In this application, expressions such as "including", "comprising", "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0037] The terms such as "upper", "lower", "left", "right", "middle", etc. used in this application are usually used to facilitate intuitive understanding by comparing with the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product. Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be regarded as the scope of this application.

[0038] Due to the high noise level of high-power units, only by reducing noise can the noise level of the units meet the current environmental protection requirements. Silent generator sets can be placed indoors or directly outdoors. For hotels, high-end living areas, large shopping malls and other places with strict requirements on environmental noise, diesel generator sets with silent boxes are indispensable emergency equipment.

[0039] In order to solve the problems existing in the prior art, the present application provides a generator set 11 silent box, see Figure 1 It mainly includes a rectangular box frame 1, which is provided with a bottom plate 2 and five installation door frames for installing a box panel 3. A circle of frame grooves is provided in the installation door frame, and sound-proof cotton (high-density foamed sound-proof cotton) is embedded in the frame groove. A fixed frame 4 is adapted to be installed on the frame groove, and the fixed frame 4 is provided with an installation socket for adapting and connecting with the box panel 3; a connecting rod is provided in the box panel 3, and an operating component 5 connected to the connecting rod and used for driving the connecting rod to move up and down is provided on the outer surface of the box panel 3. The box panel 3 is detachably connected to the installation socket on the fixed frame 4 through the connecting rod thereon.

[0040] The soundproof box provided in the present application has sound-proof cotton arranged in the frame groove of each door frame installation, and sound-proof cotton can also be arranged on the inner surface of the box panel 3 as required, or the box panel 3 can be arranged as a hollow structure. The present application realizes a multi-layer impedance mismatched silencer structure through the box sound-proof cotton design, thereby improving the noise reduction effect of the box.

[0041] In one embodiment, the box frame 1 is a steel structure frame with plastic sprayed on the surface, and the box panel 3 is a steel plate with plastic sprayed on the surface. This material is relatively heavy, has good integrity, strong compressive resistance, high rigidity, is not easy to deform, has good stability, and has functions such as noise reduction, rainproof, and rustproof. It can adapt to severe external weather and ensure use, installation, and service life.

[0042] In one embodiment, the operating component 5 that drives the patch rod to move up and down so that the box panel 3 can be detachably connected to the mounting socket on the fixed frame 4 through the patch rod thereon can be a hidden lock, such as a magnetic or spring lock. A lock hole and a corresponding mounting groove can be set on the side panel of the box to install the hidden lock. The hidden lock can include a lock body, a lock core and a control button. The control button is used to unlock the hidden lock, and the lock core is connected to the patch rod. During installation, the box panel 3 is aligned with the fixed frame 4 on the box and pressed, and the hidden lock will automatically be adsorbed on the box panel 3 to lock the box panel 3 to the box; by pressing the control button, the locking mechanism of the hidden lock is released, and the box panel 3 can be easily disassembled. The magnetic lock mainly uses the principle of magnetic adsorption. A magnet and an iron absorber are installed between the box panel 3 and the box frame 1, so that the box panel 3 can be adsorbed and locked on the box frame 1. By pressing the release button, the magnetic adsorption is broken to achieve the disassembly of the box panel 3. The spring-type lock is mainly to set a spring mechanism inside the hidden lock. When the box panel 3 is aligned with the fixed frame 4 installed on the door frame, the spring will fix the lock on the box panel 3. Pressing the control button can release the spring mechanism, allowing the box panel 3 to be separated from the box. This lock design can make the box panel 3 easier to disassemble and install when maintenance or replacement is required, while keeping the overall appearance simple and beautiful. Of course, in addition to this lock design, other existing low-cost mechanical structures can also be used, as long as they can drive the connector rod to move up and down to achieve a detachable connection.

[0043] In one embodiment, a ventilation and heat dissipation port 6 is provided on the box panel 3, and a guard plate corresponding to the ventilation and heat dissipation port 6 is provided on the inner surface of the box panel 3. The guard plate is a cylindrical structure with a rectangular cross section, and an opening corresponding to the ventilation and heat dissipation port 6 is provided on one side surface of the cylindrical structure. The plate surface of the guard plate with the opening is connected and fixed to the box panel 3. Therefore, a ventilation duct is formed in the guard plate in the present application, which plays a role in ventilation and heat dissipation. In other embodiments, the specific way of setting the ventilation duct on the box panel 3 can also be to open a plurality of through holes running through the box panel 3 or to form a connecting channel between the side walls of two adjacent box panels 3. As a further improvement, a filter screen can also be provided at the air inlet of the box panel 3 to prevent foreign matter from entering the generator cabin. As a further improvement, the ventilation duct can also be extended to the fan outside the generator set 11 body through a connecting pipe, so as to use the fan for heat dissipation. As a further improvement, a dust cover or a shutter device for adjusting the intake air volume can also be provided on the box panel 3. The material of the filter screen can be selected from a stainless steel wire mesh metal weaving or a composite filter material made of a polymer material. Among them, polymer materials refer to composite materials composed of polymers that have certain mechanical strength, can withstand impact and vibration and have certain elasticity.

[0044] The box frame 1 in the present application can be a modular component formed by splicing and assembling multiple pieces of steel materials, and the seams at each splicing location are filled with sealing strips to achieve a sealing and noise reduction effect.

The operation button 8 may include a switch button for controlling the start / stop of the power supply and operation buttons for controlling various functional electrical appliances, etc. The monitoring display panel 9 may be set as an LED screen for real-time display of various detection parameter values.

[0046] For example, in a specific application, the display screen of the monitoring display panel 9 can be designed to display the data information monitored by the tachometer, current and voltage meters, temperature sensors, fault alarm information, and the shutdown status indication of the current equipment according to the usage requirements, so as to facilitate the staff to monitor and manage scientifically.

[0047] In one embodiment, the operation button 8 is arranged near the monitoring display panel 9, and the wiring port 7 is arranged in a direction away from the monitoring display panel 9. The monitoring display panel 9 is provided with a display screen and control buttons, and the display screen is electrically connected to the controller and sends information to the controller wirelessly, so that the staff can view the information of the monitoring display panel 9 through the display screen or adjust the working parameters of the monitoring display panel 9 in real time.
