Description

Technical Field

[0001] This invention relates to the field of ventilation and air exchange equipment technology, specifically a safe ventilation and air exchange equipment for prison cells. Background Technology

[0002] With the continuous improvement of prison management standards, higher requirements are being placed on the security of cell environments and the reliability of ventilation systems. Traditional prison ventilation equipment often uses simple ventilation duct structures, lacking effective security measures, making it susceptible to damage by prisoners, leading to equipment damage or decreased ventilation efficiency. Furthermore, existing ventilation systems rely heavily on manual maintenance, resulting in infrequent cleaning, easy dust accumulation and blockage, affecting air circulation and air quality, and increasing maintenance costs and workload.

[0003] In practical applications, traditional ventilation equipment has the following shortcomings: Simple structure and insufficient security: Ordinary ventilation pipes are mostly made of ordinary metal materials, which are relatively weak and easily damaged, and cannot effectively guarantee the safety of the cells.

[0004] Lack of automated self-cleaning function: Most ventilation systems do not integrate automatic cleaning devices, and dust and debris can easily accumulate on the grilles, leading to poor ventilation and affecting air quality.

[0005] Inconvenient maintenance and low efficiency: It requires manual cleaning of the screen and replacement of the filter device regularly, which results in high maintenance costs, high labor intensity, and affects the continuous operating efficiency of the system.

[0006] Lack of intelligent control: Traditional systems are difficult to achieve automatic control and intelligent adjustment, and cannot flexibly adjust the ventilation or cleaning status according to actual needs.

[0007] Therefore, there is an urgent need for a robust, safe, reliable, and easy-to-operate prison cell ventilation system to meet the special needs of the prison environment, ensure air circulation within the cells while maintaining safety, reduce maintenance costs, and improve the system's automation level and operational efficiency. This is the technical challenge that this invention aims to solve. Summary of the Invention

[0008] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a safe ventilation and air exchange device for prison cells, thereby solving the aforementioned problems.

[0009] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a safe ventilation and air exchange device for prison cells, comprising a ventilation duct and a protective grille installed at the port of the ventilation duct. The ventilation duct contains a ventilation assembly, which includes a first cross-shaped mounting bracket that slides back and forth within the ventilation duct, a motor installed at the center of the first cross-shaped mounting bracket, a rotating shaft at the motor output end, and a plurality of fan blades evenly mounted on the rotating shaft. A self-cleaning assembly is located inside the ventilation duct near the front port, comprising a locking ring that rotates and locks onto the front port of the ventilation duct, and a cross-shaped fixing bracket installed in front of the locking ring. A plurality of cleaning brushes are evenly mounted at the front end of the cross-shaped fixing bracket, and a docking socket is installed at the center of the cross-shaped fixing bracket. A linkage plug is installed at the front end of the rotating shaft. A front-to-back drive component is located inside the ventilation duct behind the ventilation assembly, driving the entire ventilation assembly forward so that the linkage plug inserts into the docking socket.

[0010] As a preferred technical solution of the present invention, guide grooves are provided on the four sides of the ventilation duct, and a guide connector that slides back and forth with the first cross mounting bracket in the ventilation assembly is installed in each guide groove.

[0011] As a preferred technical solution of the present invention, the guide connector includes a guide post and a guide sleeve. The guide post is installed inside the guide groove, and the guide sleeve is slidably sleeved on the guide post. The inner wall of the guide sleeve is fixedly connected to the end of the first cross mounting bracket.

[0012] As a preferred technical solution of the present invention, the linkage plug is specifically configured as a plum blossom plug shape, and the inside of the plug-in end face of the docking socket is configured as a plum blossom slot shape that is compatible with the linkage plug.

[0013] As a preferred technical solution of the present invention, the front and rear drive components include a second cross mounting bracket, a stepper motor, a lead screw and a lead screw sleeve. The second cross mounting bracket is fixedly installed inside the ventilation pipe, the stepper motor is installed at the center position of the second cross mounting bracket, the lead screw is connected to the output end of the stepper motor, the lead screw sleeve is threaded onto the lead screw, and the front end of the lead screw sleeve is fixedly connected to the center position of the rear end of the first cross mounting bracket inside the ventilation assembly.

[0014] As a preferred technical solution of the present invention, the protective grid is made of high-strength steel bars welded together.

[0015] As a preferred technical solution of the present invention, the ventilation duct is made of high-strength metal material and the wall thickness is set to 3 cm.

[0016] Compared with the prior art, the present invention provides a safe ventilation and air exchange device for prison cells, which has the following beneficial effects: Robust and reliable structure: The ventilation duct is made entirely of high-strength metal with a wall thickness of 3 cm, ensuring overall strength and durability. This effectively prevents prisoner sabotage and guarantees the safe and stable operation of the cell ventilation system. The protective grille is welded with high-strength steel bars, making it sturdy and durable. It effectively prevents foreign objects from entering the ventilation duct, ensuring cell safety.

[0017] Excellent ventilation and air exchange: The ventilation components are equipped with a motor-driven shaft and multiple evenly distributed fan blades, which can efficiently promote airflow, achieve effective air exchange in the cell, ensure fresh air, and improve the comfort and security of the prison environment.

[0018] Self-cleaning function, easy maintenance: This invention innovatively sets up a self-cleaning component, which, through the mechanical linkage connection between the linkage plug and the docking socket, enables the motor to drive the ventilation fan blades while simultaneously rotating the dust cleaning brush, thus cleaning the protective grille in a timely manner, automatically removing accumulated dust and debris, effectively preventing ventilation blockage, ensuring the long-term efficient operation of the ventilation system, and reducing the frequency and intensity of manual maintenance.

[0019] The front and rear drive mechanism enables flexible adjustment of component positions: the front and rear drive components, consisting of a stepper motor, a lead screw and a lead screw sleeve, enable precise front and rear movement of the ventilation component in the ventilation duct, allowing the linkage plug to connect or disconnect from the self-cleaning component, flexibly control the start and stop of the self-cleaning function, and improve the system's intelligence level and ease of operation.

[0021] In summary, this invention, through multiple technological innovations, constructs an intelligent ventilation system integrating security protection, ventilation, and self-cleaning maintenance. This system not only ensures cell security and ventilation efficiency but also significantly improves the equipment's self-maintenance capabilities and ease of use, reducing maintenance costs and labor intensity, and greatly enhancing the overall performance and reliability of prison ventilation equipment. Its rational structural design and comprehensive functions are adapted to the complex and harsh environment of prisons, possessing broad application prospects and promotional value, and providing strong technical support for prison security management and environmental improvement.

[0027] Please see Figure 1-7A safe ventilation system for prison cells includes a ventilation duct 1 and a protective grille 2 installed at the port of the ventilation duct 1. The ventilation duct 1 is made entirely of high-strength metal with a wall thickness of 3 cm, ensuring structural strength and safety and preventing prisoners from breaking into it.

[0028] Ventilation duct 1 houses a ventilation assembly 3, which includes a first cross-shaped mounting bracket 31 that slides and engages with the ventilation duct 1. A motor 32 is mounted at the center of the first cross-shaped mounting bracket 31, and a rotating shaft 33 is mounted at the output end of the motor 32. Several fan blades 34 are evenly fixed on the rotating shaft 33 to achieve effective airflow and ventilation. A linkage plug 4 is mounted at the front end of the rotating shaft 33. The linkage plug 4 is specifically designed as a quincunx plug, compatible with the docking socket 54 mounted at the center of the cross-shaped fixing bracket 52 in the self-cleaning assembly 5, enabling an electrical or mechanical linkage connection between the rotating shaft and the self-cleaning assembly.

[0029] A self-cleaning component 5 is installed inside the ventilation duct 1 near the front port. The self-cleaning component 5 includes a snap-fit ​​ring 51 that is rotatably snapped into the front port of the ventilation duct 1. A cross-shaped fixing bracket 52 is fixedly installed on the front side of the snap-fit ​​ring 51. Several cleaning brushes 53 are evenly installed at the four ends of the cross-shaped fixing bracket 52. A docking socket 54 is installed in the center of the cross-shaped fixing bracket 52 for connecting with the linkage plug 4 at the front end of the rotating shaft 33. When connected, when the motor 32 drives the rotating shaft 33 to rotate, the linkage plug 4 rotates accordingly, thereby driving the docking socket 54 to rotate, ultimately driving the cross-shaped fixing bracket 52 to rotate, and thus cleaning the protective grille 2 through the front cleaning brushes 53.

[0030] A front-to-back drive component 6 is located behind the ventilation component 3. This drive component moves the ventilation component 3 back and forth along the ventilation duct 1, allowing the linkage plug 4 to be inserted into the docking socket 54. This enables the linkage between the self-cleaning component and the ventilation component, thus allowing the operation of activating or deactivating the self-cleaning component 5. The front-to-back drive component 6 includes a second cross-shaped mounting bracket 61, a stepper motor 62, a lead screw 63, and a lead screw sleeve 64. The second cross-shaped mounting bracket 61 is fixedly installed inside the ventilation duct 1. The stepper motor 62 is mounted at the center of the second cross-shaped mounting bracket 61. The output end of the stepper motor 62 is connected to the lead screw 63. The lead screw sleeve 64 is threaded onto the lead screw 63, and its front end is fixedly docked to the center of the rear end of the first cross-shaped mounting bracket 31. The stepper motor 62 drives the lead screw 63 to rotate, causing the lead screw sleeve 64 to move axially along the lead screw 63, thereby realizing the front-to-back movement of the ventilation component 3.

[0031] To ensure stable sliding of the ventilation component 3 within the ventilation duct 1, guide grooves 11 are provided on the four sides of the ventilation duct 1, and a guide connector 7 is installed in each guide groove 11. The guide connector 7 includes a guide post 71 and a guide sleeve 72. The guide post 71 is fixedly installed inside the guide groove 11, and the guide sleeve 72 is sleeved on the guide post 71 and can slide. The inner wall of the guide sleeve 72 is fixedly connected to the end of the first cross mounting bracket 31, so that the first cross mounting bracket 31 remains stable and prevents shaking when it slides back and forth along the direction of the guide groove 11 within the ventilation duct 1.

[0032] The protective grille 2 is made of high-strength steel bars, which are sturdy and durable. It can effectively prevent external objects from entering the ventilation duct 1 and ensure the safety of the cell.

[0033] The workflow for cleaning protective grilles is as follows: When a large amount of dust adheres to the protective grille 2, the motor 32 in the ventilation assembly 3 is first shut down, and then the stepper motor 62 in the front and rear drive components 6 is started. The stepper motor 62 drives the lead screw 63 to rotate, causing the lead screw sleeve 64 to move forward along the axial direction of the lead screw 63. Since the front end of the lead screw sleeve 64 is fixedly connected to the center of the rear end of the first cross mounting bracket 31, the entire ventilation assembly 3 slides smoothly forward along the guide groove 11 in the ventilation pipe 1 under the guidance of the guide connector 7.

[0034] As the ventilation assembly 3 moves forward, the plum blossom-shaped linkage plug 4 at the front end of the rotating shaft 33 gradually inserts into the docking socket 54 at the center of the cross-shaped fixing bracket 52 in the self-cleaning assembly 5, thus achieving a mechanical linkage connection between the rotating shaft 33 and the self-cleaning assembly 5. After the connection is completed, the motor 32 is started again, driving the rotating shaft 33 and the fan blade 34 to rotate. At the same time, the linkage plug 4 drives the docking socket 54 to rotate, thereby driving the cross-shaped fixing bracket 52 to rotate.

[0035] The cleaning brushes 53, evenly installed at all four ends of the cross-shaped fixing bracket 52, rotate to thoroughly clean the protective grille 2, effectively removing dust and debris from the grille. After cleaning, the stepper motor 62 reverses its direction, causing the lead screw sleeve 64 to retract. The ventilation component 3 slides backward along the guide groove 11, the linkage plug 4 separates from the docking socket 54, the self-cleaning component 5 stops rotating, and the ventilation component 3 returns to its normal ventilation position, thus completing the entire cleaning process for the protective grille 2.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
