Description

Technical Field

[0001] This utility model relates to the field of warehouse safety technology, and in particular to an explosion-suppressing ventilation structure for flammable goods warehouses. Background Technology

[0002] Flammable goods warehouses are important locations for storing and preserving flammable and explosive materials, and the safety of their internal environment is paramount. Effective ventilation and heat dissipation are fundamental technical means to ensure the safe operation of warehouses, preventing combustion or explosion accidents caused by excessively high temperatures or the accumulation of flammable gas concentrations.

[0003] Currently, conventional flammable goods warehouses typically rely on ventilation devices such as exhaust fans or louvers installed on the walls for daily air exchange and temperature regulation. Under normal operating conditions, these devices can maintain a relatively stable internal environment, slowly removing heat and expelling potentially volatile gases through continuous air exchange.

[0004] However, when abnormal situations occur inside the warehouse, such as a chemical undergoing a rapid exothermic reaction that causes a sharp rise in internal temperature within a short period, the fixed or limited ventilation capacity of the aforementioned conventional ventilation systems becomes inadequate. Their rate of heat removal and gas dilution cannot keep up with the rate of heat and gas generation under abnormal conditions, causing the temperature and pressure inside the warehouse to rapidly approach dangerous thresholds.

[0005] It is evident that existing ventilation structures are primarily designed for routine, moderate ventilation needs, lacking a mechanism capable of rapidly responding in emergencies and providing massive airflow for forced cooling and exhaust. This inadequacy in handling sudden heat buildup poses a serious safety hazard and makes true explosion suppression difficult.

[0006] Therefore, this utility model proposes an explosion-suppressing ventilation structure for flammable goods warehouses to address the shortcomings of existing technologies. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides an explosion-suppressing ventilation structure for flammable goods warehouses, aiming to improve the existing explosion-suppressing ventilation structures for flammable goods warehouses, which have insufficient heat dissipation efficiency when dealing with sudden high temperatures and have a relatively cumbersome maintenance process for their ventilation and filtration devices.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an explosion-suppressing ventilation structure for a flammable goods warehouse, comprising a wall, a door, and an opening and closing assembly for driving the door; the opening and closing assembly comprises an electric push rod, a rotating shaft, a rotating plate, a rotating block, and a fixing block.

[0009] The output end of the electric actuator drives a rotating shaft to move linearly. This linear movement of the shaft causes a rotating plate to rotate, which in turn causes a rotating block to rotate synchronously and a fixed block to move. The fixed block is fixed to the door, and its movement drives the door, which is mounted on the wall, to open or close.

[0010] Preferably, the electric actuator is fixedly installed on the wall via a support plate and a connecting block.

[0011] Preferably, the opening and closing assembly further includes a fixing plate, which is used to rotatably support the rotating block.

[0012] Preferably, the structure also includes a ventilation assembly mounted on the wall, which includes a cooling fan and a filter.

[0013] Preferably, the ventilation assembly further includes a handle, a locking block, and a locking slot for removing and installing the filter screen; the handle is fixedly connected to the filter screen, the locking block is located on the filter screen, and the locking slot is formed on the housing of the ventilation assembly.

[0014] Preferably, the structure also includes a fireproof mesh, which is installed on the wall, and the door rotates along the side wall of the fireproof mesh when opening and closing.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by setting a linkage-type opening and closing assembly driven by an electric push rod to automatically control the opening and closing of the door, the problem of existing ventilation structures of flammable goods warehouses being unable to quickly increase the ventilation area for effective heat dissipation in the face of emergencies such as a sudden rise in internal temperature is solved. The technical effect of being able to quickly open large-size doors as needed, thereby significantly improving air circulation efficiency in a short time, quickly dissipating heat and flammable gases, and effectively suppressing the risk of explosion is achieved.

[0016] 2. In this utility model, by setting a quick-release structure on the ventilation component, which consists of a handle, a locking block, and a locking slot, the problem of cumbersome filter installation and removal process and inconvenient maintenance in existing ventilation equipment is solved. This simplifies the cleaning and replacement process of the filter, allowing maintenance personnel to complete the operation quickly, thereby ensuring the long-term stability of the ventilation system's filtration efficiency and improving the practicality and maintainability of the structure.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-6 The present invention provides an embodiment of an explosion-suppressing ventilation structure for flammable goods warehouses, which aims to solve the problems of insufficient heat dissipation efficiency and inconvenient maintenance of filtration devices in existing ventilation structures for flammable goods warehouses when dealing with sudden high temperatures.

[0021] The explosion-suppressing ventilation structure for a flammable goods warehouse includes a wall 1 and an openable door 5 installed on the wall 1; a top cover 3 is also provided on the top of the wall 1, and the wall 1 and the top cover 3 together enclose a space for storing flammable goods; the structure also includes an opening and closing assembly 6 for driving the door 5, and a ventilation assembly 4 and a fireproof mesh 2 installed on the wall 1. Specifically, the opening and closing assembly 6 includes an electric push rod 603, a rotating shaft 604, a rotating plate 605, a rotating block 607, and a fixed block 608. The output end of the electric push rod 603 is connected to the rotating shaft 604 for driving the rotating shaft 604 to move linearly. The linear movement of the rotating shaft 604 will drive the rotating plate 605 to rotate. When the rotating plate 605 rotates, it will drive the rotating block 607 to rotate synchronously. At the same time, the rotating plate 605 will drive the fixed block 608 to move. The fixed block 608 is fixed to the opening and closing door 5, so that the opening and closing action of the opening and closing door 5 is achieved by the movement of the fixed block 608. The opening and closing door 5 rotates along the side wall of the fireproof mesh 2 to quickly increase air circulation. To ensure the stability of the opening and closing assembly 6, the electric push rod 603 is fixedly installed on the wall 1 through the support plate 601 and the connecting block 602; the opening and closing assembly 6 also includes a fixing plate 606, which is used to rotate and support the rotating block 607.

[0022] The electric push rod 603 serves as the power source and is fixedly mounted on the wall 1 via the support plate 601 and the connecting block 602. Its output end drives the rotating shaft 604 to move linearly. During the movement of the rotating shaft 604, it drives the rotating plate 605 to rotate around the shaft at one end. The rotation of the rotating plate 605 drives the rotating block 607 to rotate synchronously. To ensure the smoothness of the rotation process, the rotating block 607 is rotatably supported on the wall 1 via the fixing plate 606. While the rotating plate 605 is rotating, it also drives the fixed block 608, which is linked to it, to move. Since the fixed block 608 is fixedly connected to the switch door 5, the movement of the fixed block 608 ultimately drives the switch door 5 to open or close. This linkage transmission structure driven by the electric push rod ensures that the switch door 5 can be stably driven to open and close, thereby quickly increasing the ventilation area when needed to achieve rapid heat dissipation and explosion suppression.

[0023] To achieve effective ventilation and air filtration inside the warehouse, the structure also includes a ventilation component 4 installed on the wall 1; the ventilation component 4 includes a cooling fan 405 for exchanging air and a filter screen 401 for filtering impurities; to facilitate maintenance of the filter screen 401, the ventilation component 4 is also provided with a structure for quick disassembly and assembly, which includes a handle 402 fixedly connected to the filter screen 401, a locking block 403 installed on the filter screen 401, and a slot 404 opened on the housing of the ventilation component 4, wherein the locking block 403 and the slot 404 cooperate with each other; The structure also includes a fireproof mesh 2, which is installed on the wall 1, and the door 5 rotates along the side wall of the fireproof mesh 2, so that it still maintains fireproof barrier capability when the door is opened for ventilation; in addition, in order to protect the items inside the warehouse, a top cover 3 is also installed on the top of the wall 1.

[0024] Working principle: During daily use, the cooling fan 405 inside the ventilation assembly 4 runs continuously, drawing in outside air through the filter 401 to ventilate the warehouse. When the filter 401 needs cleaning or replacement, turn the handle 402. The handle 402 drives the filter 401 to rotate, causing the locking block 403 on the filter 401 to align with and disengage from the locking groove 404 on the housing of the ventilation assembly 4. The filter 401 can then be pulled out directly, making the operation convenient. When the warehouse needs urgent or rapid heat dissipation, the opening and closing assembly 6 is activated. The output end of the electric push rod 603 drives the rotating shaft 604 to move linearly. As the rotating shaft 604 moves, it drives the rotating plate 605 to rotate. The rotation of the rotating plate 605 further drives the rotating block 607 and the fixed block 608 to move synchronously. Finally, the fixed block 608, which is fixedly connected to the opening and closing door 5, drives the opening and closing door 5 to open, rapidly increasing the ventilation area. Through the synergy with the ventilation assembly 4, the air circulation efficiency is greatly improved, thus solving the problem of untimely heat dissipation in the prior art.
