Detailed implementation manners

[0032] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0033] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0034] Such as Figures 1-9The energy-saving ventilation alarm system for a communication room shown in the figure comprises a room 1, a main control terminal 2 and a ventilation control group 3 are arranged on one side of the outside of the room 1, an Ethernet transmission terminal 4 is arranged on one side of the inner wall of the room 1, and multiple groups of bridge frames 5 are arranged on the top wall inside the room 1, one of which is provided with a regulating mechanism on one side of the outside of one group of bridge frames 5, and the regulating mechanism also comprises two groups of fixed frames 6 arranged symmetrically, and one end of the inside of the two groups of fixed frames 6 is provided with a fixed component installed on the outside of the bridge frame 5, and the outside of the two groups of fixed frames 6 is fixedly provided with a support frame 32, and the outside of one group of support frames 32 is provided with a card shell 10 through a mobile component, and an audible and visual alarm 9 and a temperature sensor 8 are arranged inside the card shell 10, and the temperature sensor 8 is located on one side of the audible and visual alarm 9 and the two are connected by a connecting signal line, and also comprises the following use steps:

[0035] Step 1: Start the temperature sensor 8 and monitor each area by moving the mobile component back and forth horizontally;

[0036] Step 2, the temperature sensor 8 performs real-time monitoring according to the preset temperature difference range. When the temperature difference changes, an alarm is sounded through the sound and light alarm 9, and then the Ethernet transmission terminal 4 transmits the data to the main control terminal 2;

[0037] Step 3: The main control terminal 2 starts the ventilation control group 3 according to the feedback data, and the ventilation fan outside the computer room 1 can ventilate the inside of the computer room 1.

[0038] The process of the operating system is that the temperature sensor 8 can monitor the temperature of different spatial areas inside the computer room 1 as the mobile component moves, and then perform corresponding sensing according to the originally set temperature difference. When the temperature is different, the data is uploaded to the main control terminal 2 through the signal line and the Ethernet transmission terminal 4. Then, according to the abnormal reception of the data, the sound and light alarm 9 will alarm when the temperature difference is incorrect, alerting the relevant personnel. Then the relevant workers start the ventilation control group 3 through the connection between the main control terminal 2 and the external display screen, prompting the ventilation control group 3 to allow the ventilation fan or ventilation equipment inside the computer room 1 to operate.

[0039] The fixing assembly includes a slide 13 slidably mounted inside the fixing frame 6 , one side of the outer wall of the slide 13 is connected to the abutment frame 12 via a connecting assembly, and a wire clamping member is arranged inside the abutment frame 12 .

[0040] The connecting component includes a fixing plate 19 fixedly installed on one side of the outer wall of the carriage 13. On the outer surface of the fixing plate 19, clamping blocks 20 are symmetrically installed. On the inner sides of the two clamping blocks 20, clamping rods 21 are rotatably installed. The clamping rods 21 can accommodate the abutting frame 12 at the maximum angle through the structure of rotatably cooperating with the clamping blocks 20 at the upper ends. On the outer sides of the clamping rods 21, telescopic cylinders 23 are rotatably installed. Inside the telescopic cylinders 23, telescopic rods 24 are slidably installed. One end of the telescopic rod 24 away from the telescopic cylinder 23 is connected to a bushing 16. Inside the bushing 16, a clamping shaft is rotatably installed. At both ends of the clamping shaft, sliders 14 are respectively arranged. On both sides of the upper surface of the abutting frame 12, sliding grooves adapted to the sliding of the sliders 14 are opened. Inside the upper part of the telescopic cylinder 23, a clamping pin is threaded. The lower end of the clamping pin abuts against the outer surface of the telescopic rod 24. The wire clamping member includes a silicone seat 15 fixedly installed inside the abutting frame 12, and a plurality of ventilation grooves are opened on the upper surface of the silicone seat 15. On one outer wall of the abutting frame 12, a mounting block 22 is fixedly arranged. The mounting block 22 and the clamping rod 21 are rotatably matched. After the position of the fixing frame 6 is determined, the abutting frame 12 can be placed on the cable on the inner surface of the cable tray 5. Then, through the telescopic drive of the telescopic rod 24, the slider 14 is pushed, and then the abutting frame 12 and the silicone seat 15 are driven to be closely attached to the surface of the cable. Subsequently, by screwing in the clamping pin, the position of the telescopic rod 24 is limited. Thus, the abutting frame 12 and the silicone seat 15 can press against the surface of the cable, thereby reducing the consumption of the wire clamping structure subsequently installed at the cable tray 5.

[0041] The moving component includes a U-shaped frame 27 fixedly installed on the outside of one of the support frames 32. Inside the corresponding support frame 32, a clamping cylinder 33 is penetrated and connected. Inside the clamping cylinder 33, a rotating cylinder 25 is rotatably installed. A steel cable 29 is wound around the outside of the rotating cylinder 25. One end of the steel cable 29 is fixedly wrapped around the outside of the rotating cylinder 25. When it is necessary to pay out the cable, the rotating cylinder 25 can be rotated forward, so that the fixing frame 6 at the other end can be installed towards the other end of the cable tray 5. This method can be used to meet the lengths of different ladder-type cable trays 5, and thus meet the use of different-sized computer rooms 1. One end of the rotating cylinder 25 away from the clamping cylinder 33 is fixedly provided with a counterweight plate 26. On the outer surface of the counterweight plate 26, a plurality of clamping holes 30 are opened. Inside the lower part of the U-shaped frame 27, a counterweight rod 28 is threaded. One end of the counterweight rod 28 correspondingly extends into one of the clamping holes 30. After determining the use length of the steel cable 29, the worker rotates the counterweight rod 28 from the lower end, so that one end of the counterweight rod 28 is inserted into the corresponding clamping hole 30, thereby fixing the positions of the rotatable counterweight plate 26 and the rotating cylinder 25. Combined with the steel cable 29 fixedly arranged at the other end and the fixing frame 6, the length of the steel cable 29 is synchronized with the length of the cable tray 5.

[0042] One end of the steel rope 29 away from the rotating drum 25 is connected to the outer side of the support frame 32 on the other side. A positioning seat 34 is arranged above the outside of the steel rope 29. Bearings are arranged on both sides of the inner wall of the positioning seat 34, and a mounting shaft is rotatably arranged inside the two bearings together. A traveling wheel 40 is arranged on the outside of the mounting shaft. One end of the mounting shaft penetrates through the outside of the positioning seat 34 and is connected with a driving motor 35 at the end. The bearings are sleeved at both ends of the mounting shaft and can be driven in cooperation with the driving motor 35, and then drive the traveling wheel 40 to roll. The driving motor 35 is arranged outside the positioning seat 34. A support assembly is arranged above the inside of the positioning seat 34. Slide rods 42 are fixedly installed on both sides of the bottom of the positioning seat 34. Rope pressing assemblies are arranged on both sides of the outside of the slide rods 42. The traveling wheel 40 rolls and fits on the upper end of the steel rope 29, and the slide rods 42 keep balance on both sides of the steel rope 29 and assist in installing the rope pressing assemblies, so as to enable the traveling wheel 40 to drive the temperature sensor 8 at the lower end to move, so as to achieve the purpose of regulating the use position of the temperature sensor 8.

[0043] The support assembly includes an L-shaped rod 31 fixedly installed above the inside of the positioning seat 34. A balance wheel set 36 is arranged at one end of the L-shaped rod 31 away from the positioning seat 34. The balance wheel set 36 rolls and fits on the upper surface of the bridge 5. Under the connection of the L-shaped rod 31, the balance wheel set 36 can assist the balance of the traveling wheel 40 on the upper surface of the bridge 5. As the traveling wheel 40 rolls, the positioning seat 34 can be stably supported on one side by means of the balance wheel set 36.

[0044] The rope pressing assembly includes a shaft rod 39 slidably installed at one end of the outside of the slide rod 42. A side wheel 38 is arranged inside one end of the shaft rod 39 away from the slide rod 42. The shaft rod 39 can slide on the outside of the slide rod 42 to adjust the use position of the two groups of side wheels 38. The side wheels 38 are located at the lower end of the steel rope 29. A counterweight rod 37 is arranged at the lower end of the slide rod 42. The two counterweight rods 37 are connected to the top of the cartridge case 10 through a common connecting rod 18. The arrangement of the counterweight rod 37 enables the traveling wheel 40 and the side wheels 38 to move more stably at the lower end of the steel rope 29. A plurality of groups of positioning holes 43 are symmetrically formed on the outer surface of the slide rod 42. The two shaft rods 39 are inserted into two positioning holes 43 at corresponding positions through a common U-shaped pin 41 inserted through the outside. The insertion of the U-shaped pin 41 can lock the positions of the two shaft rods 39, so as to ensure that the side wheels 38 can assist in supporting on both sides of the lower end of the traveling wheel 40.

[0045] A fastening screw rod 7 is inserted into the inside of the sliding frame 13 in a threaded manner. A resisting seat 17 is fixedly arranged at one end of the fastening screw rod 7. By rotating the fastening screw rod 7, the resisting seat 17 can be on the inner surface of the bridge 5 to fix the positions of the sliding frame 13 and the fixing frame 6. One end of the resisting seat 17 abuts against the inner surface of the bridge 5. Mounting rods 11 are symmetrically arranged at both ends of the outside of the bridge 5. Through the arranged mounting rods 11, the bridge 5 can be installed on the inner top wall of the machine room 1.

[0046] Working principle: When in use, the pre-installed bridge 5 can be stably installed on the inner top wall of the computer room 1 through multiple mounting rods 11. Then, the distance between the two sets of fixing frames 6 is set according to the length of the bridge 5. First, install the fixing frame 6 corresponding to the clamping cylinder 33. The worker unscrews the fastening screw 7 to make the fixing frame 6 clamp against the outer side of the bridge 5, and the sliding frame 13 abuts against the upper surface of the bridge 5. Then, the abutment 17 is pushed to the inner surface of the bridge 5 by rotating the fastening screw 7. After the fixing frame 6 and the sliding frame 13 are fixed, the abutting frame 12 can abut against the cables at the inner surface of the bridge 5. Then, by stretching the telescopic rod 24, the two sliders 14 inside the abutting frame 12 are made to move in the corresponding sliding grooves, driving the abutting frame 12 to press parallel against the surface of the cables. In this way, the cables at the bridge 5 can be clamped, making the cables inside the bridge 5 more regular. After completion, the steel cable 29 on the outer side of the rotating cylinder 25 is pulled to the other end of the bridge 5, and then, by the above operation method, the fixing frame 6 connected to the other end of the steel cable 29 is installed on the outer side of the bridge 5. The traveling wheels 40 can then roll on the upper end of the steel cable 29 driven by the drive motor 35. Then, the two shaft rods 39 are adjusted so that the side wheels 38 inside the shaft rods 39 abut against the lower end of the steel cable 29, and the balance wheel group 36 on one side of the positioning seat 34 rolls on the upper surface of one side of the bridge 5. In this way, the temperature sensor 8 at the lower end of the positioning seat 34 can be made to move horizontally and stably above the computer room 1. By adjusting the position, the temperature sensor 8 can quickly capture the temperature changes inside the computer room 1, and then, through ventilation, the internal temperature can be regulated and warned.
