Description

Technical Field

[0001] The invention relates to the technical field of machine room ventilation systems, and in particular to an intelligent temperature control ventilation system for a radio and television transmission machine room. Background Art

[0002] In the radio and television transmission room, a ventilation system needs to be installed. As the power density of the transmitting equipment continues to increase, the temperature inside the room is also getting higher and higher. The ventilation system can realize the air interaction between the inside and outside of the room, so as to achieve the purpose of cooling the room. With the development of science and technology, the ventilation system inside the room is becoming more and more intelligent. The temperature inside the room can be monitored in real time through the temperature sensing system, and the temperature information can be fed back to the control system. The control system adjusts the opening and closing status of the ventilation system and the power used according to the temperature data.

[0003] However, as far as the existing intelligent temperature control ventilation system of the radio and television transmission room is concerned, there is no blocking structure on the outside of its air flow channel, which means that the air flow channel is always in an open state regardless of whether the fan is working or not, making it easy for external impurities and dust to enter the room, causing damage to the machines and equipment inside the room. In addition, excessive air intake in summer will increase the air conditioning load, and ineffective air intake in winter will aggravate heat loss. In addition, the fully open air flow channel needs to be closed manually during the rainy season or sandstorm weather, which increases the workload of operation and maintenance and affects the stability of the equipment. The fully open air flow channel cannot form a dynamic match with the fan power. When the fan is running at low power, part of the air intake will be invalid airflow, resulting in energy waste and poor practicality. Summary of the invention

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 13 As shown: The present invention provides an intelligent temperature control ventilation system for a radio and television transmitter room, comprising a temperature sensing system, a ventilation system and a control system. The temperature sensing system comprises a plurality of temperature control sensors, and the control system can control the working state of the ventilation system. The ventilation system consists of an installation component 1, an air guide component 2 and an opening and closing component 3. The mounting assembly 1 includes a mounting seat 101 and a drive motor 102. The mounting seat 101 is mounted on the wall of the machine room, and the two sides of the mounting seat 101 are respectively located inside and outside the machine room. The drive motor 102 is fixedly mounted on one side of the mounting seat 101 located inside the machine room; the air guide assembly 2 includes an air guide tube 201, an integral seat 202, a guide seat 203, a linkage frame 204 and a centrifugal block 205. The air guide tube 201 is rotatably connected to the inside of the mounting seat 101, and the integral seat 202 is rotatably connected to the The guide seat 203 is axially inserted into the side of the integral seat 202 on the outside of the air guide tube 201, the linkage frame 204 is rotatably connected to the outside of the guide seat 203, and the linkage frame 204 is inserted into the inside of the mounting seat 101, and the centrifugal block 205 is inserted into the inside of the air guide tube 201 along the radial direction of the air guide tube 201; the opening and closing component 3 includes an opening and closing baffle 301 and an opening and closing rod 302, the opening and closing baffle 301 is rotatably connected to the inside of the mounting seat 101, and the opening and closing rod 302 is inserted into the inside of the mounting seat 101.

[0034] Among them, the inside of the air guide tube 201 is fixedly installed with fan blades 4 and a dustproof frame 5, and the inside of the dustproof frame 5 is provided with a dustproof filter. The rotating shaft of the driving motor 102 and the air guide tube 201 are connected by a gear set. The insides of the air guide tube 201 and the mounting base 101 are both provided with air guide ducts. The fan blades 4 directly drive the airflow when the air guide tube 201 rotates. Combined with the air guide duct design, the ventilation effect can be efficiently achieved. The physical closure of the dustproof filter and the opening and closing component 3 forms double protection to ensure the cleanliness of the machine room environment.

[0035] Among them, an arc-shaped driving groove 2021 is provided on the side of the integral seat 202, and a driving lever 2051 is provided on the side of the centrifugal block 205, and the driving lever 2051 is inserted into the inside of the driving groove 2021. The cooperation between the driving groove 2021 and the driving lever 2051 converts the moving action of the centrifugal block 205 into the rotation action of the integral seat 202, so that the response speed of the opening and closing component 3 is always synchronized with the motor speed.

[0036] Among them, a reset top spring 2052 is provided inside the centrifugal block 205, and the two ends of the reset top spring 2052 respectively abut against the inside of the centrifugal block 205 and the inside of the air guide tube 201. The reset top spring 2052 enables the centrifugal block 205 to quickly reset after the motor stops, automatically restoring the closed state of the air guide duct, forming an automatic cycle of "ventilation with electricity and dust prevention without power".

[0037] A track block 2022 with a regular polygonal cross section is disposed on the side of the integral seat 202 , and a track groove 2031 is disposed inside the guide seat 203 , and the track block 2022 is inserted into the track groove 2031 .

[0038] Among them, a spiral guide groove 2011 is provided on the outside of the cylinder body of the air guide cylinder 201, and a guide protrusion 2032 is provided on the inside of the guide seat 203, and the guide protrusion 2032 is inserted into the inside of the guide groove 2011, a linkage lever 2041 is provided on the side of the linkage frame 204, and an inclined linkage groove 3021 is provided on the side of the opening and closing rod 302, and the linkage lever 2041 is inserted into the inside of the linkage groove 3021, an opening and closing gear 3011 is provided on the outside of the rotating shaft of the opening and closing baffle 301, and an opening and closing rack 3022 is provided on the side of the opening and closing rod 302, and the opening and closing gear 3011 and the opening and closing rack 3022 are meshed with gear transmission. This design enables the opening and closing state of the opening and closing component 3 to be automatically linked and controlled with the working state of the drive motor 102, which is convenient and flexible to use.

[0039] Among them, the opening and closing component 3 is arranged on the side of the mounting base 101 outside the machine room. This design is convenient for air circulation and can block dust intrusion through the outer closed structure, thereby improving the protection performance.

[0040] In the present invention, the temperature sensing system can sense the temperature information in the machine room and send the temperature information to the control system in real time. After receiving the temperature information, the control system can send a working signal to the drive motor 102 according to the temperature condition in the machine room. When the drive motor 102 is not powered on, the air guide tube 201 will not rotate, so that the centrifugal block 205 will not generate centrifugal force. Under the action of the reset top spring 2052, the centrifugal block 205 is located at the innermost end of the air guide tube 201, so that the driving lever 2051 of the centrifugal block 205 can be linked to position the use position and state of the integral seat 202, the guide seat 203, the linkage frame 204 and the opening and closing rod 302, so that the opening and closing baffle 301 is used in a vertical state, and the air guide duct of the mounting seat 101 is sealed. The air duct is physically shielded to prevent a large amount of dust and impurities from entering the machine room and causing damage to the machine and equipment. The driving motor 102 can generate airflow through the air guide assembly 2, thereby realizing ventilation and air exchange operations in the machine room. It is easy to use. When the driving motor 102 rotates, its shaft can drive the air guide tube 201 to rotate through the gear set. When the air guide tube 201 rotates, it can drive the fan blades 4 to rotate synchronously. When the fan blades 4 rotate, they can arouse airflow, thereby introducing the outside air into the machine room through the air guide duct or discharging the hot air in the machine room through the air guide duct, thereby realizing ventilation and air exchange operations. When the airflow enters and exits the air guide duct, the dust and impurities in the airflow can be removed by the dustproof frame 5. The filter screen blocks to prevent dust and impurities from entering the room. When the driving motor 102 is working, the opening and closing component 3 can automatically open and release the blocked state of the air guide duct. When the driving motor 102 rotates, its rotating shaft can drive the air guide tube 201 to rotate through the gear set to generate airflow. When the air guide tube 201 rotates, the centrifugal block 205 will also rotate with the air guide tube 201. The centrifugal block 205 will generate centrifugal force when rotating, so that the centrifugal block 205 moves toward the outer end of the air guide tube 201 and compresses the reset top spring 2052. When the centrifugal block 205 moves, the driving lever 2051 can drive the integral seat 202 to rotate independently of the air guide tube 201 through the driving groove 2021. When the integral seat 202 rotates independently of the air guide tube 201, the track block 2022 can The guide seat 203 can be driven to rotate independently of the air guide tube 201 through the track groove 2031. When the guide seat 203 rotates independently of the air guide tube 201, the guide protrusion 2032 can drive the guide seat 203 to move in the axial direction of the air guide tube 201 through the guide groove 2011. When the guide seat 203 moves, it can drive the linkage frame 204 to move synchronously. When the linkage frame 204 moves, the linkage lever 2041 can drive the opening and closing rod 302 to move upward through the linkage lever groove 3021. When the opening and closing rod 302 moves upward, the opening and closing rack 3022 can drive the opening and closing baffle 301 to rotate through the opening and closing gear 3011, thereby releasing the blocked state of the air guide duct, and the airflow can move and circulate inside the air guide duct through the space opened by the opening and closing baffle 301.Thus, the operation of indoor and outdoor ventilation of the machine room is realized. The opening of the opening and closing component 3 can form a dynamic match with the power of the drive motor 102, so as to accurately control the air intake to match it with the cooling demand, and avoid the phenomenon of energy waste caused by invalid airflow. The greater the power of the drive motor 102, the faster the speed of the drive motor 102 driving the air guide tube 201, and the greater the distance the centrifugal block 205 moves. The moving distance of the centrifugal block 205 can be linked to the upward movement distance of the opening and closing rod 302, so that the upward movement distance of the opening and closing rod 302 will also be greater, and then the rotation angle of the opening and closing baffle 301 will be greater, that is, the opening degree will be greater. The above functions are completely automatically controlled according to the actual working power of the drive motor 102, without human intervention, and the degree of automation is high. When the drive motor 102 is turned off, the centrifugal force obtained by the centrifugal block 205 through the air guide tube 201 will gradually disappear, so that under the action of the reset top spring 2052, the opening and closing component 3 will return to the blocking state of the air guide duct again.
