Specific embodiments

[0022] The technical solution of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] As Figure 1 , Figure 2 and Figure 3 , a new type of gas alarm box with remote monitoring includes a box body 7, a box cover 2, a locking assembly 1, an alarm system and a control unit. The box body 7 and the box cover 2 are rotatably connected by two upper and lower hinges. A locking assembly 1 is installed at the middle position on the left side of the box cover 2, and it can be locked or unlocked by simply pressing, which is convenient for the maintenance and adjustment of the alarm box. In the middle part of the front surface of the box cover 2, there is an observation window, which is embedded with transparent tempered glass. This observation window can be one, or multiple ones corresponding one by one to the connecting pipeline 6 and having the same shape and size, which is convenient for observing the inside of the alarm box.

[0024] The box body 7 also includes a connecting pipeline 6. The top of the connecting pipeline 6 is connected with a pipe nipple 14, which is convenient for the quick connection of the alarm box to the gas pipeline. The pipe nipple 14 is connected to a union straight-through 12 through a copper pipe 13. The union straight-through 12 is connected to a maintenance valve 11 by thread. A label corresponding to the gas is pasted on the outside of the maintenance valve 11, that is, on the side close to the observation window of the box cover 2. The staff can quickly judge the type of gas in the pipeline through the label through the glass outside the box body 7. The bottom of the maintenance valve 11 is connected with a three-way connecting block. The rear end of this connecting block is fixed to the inner wall of the rear side of the box body 7 by screws, and the front end is connected with a pressure gauge 9. The pressure gauge 9 is used to display the real-time pressure value of the pipeline. The lower end of the three-way connecting block is connected with a pressure sensor 10. The pressure sensor 10 is used to measure the pressure in the pipeline in real time and transmit the collected data to the data acquisition board for processing.

[0025] A whole acrylic plate 4 is inlaid at the bottom of the front of the box cover 2. A plurality of alarm lights 5 are arranged at equal intervals on the front of the acrylic plate 4. The back of the acrylic plate 4 uses a black shiny background. At the position of each alarm light 5, the corresponding black background is in a transparent circular ring shape. A corresponding circuit board is installed behind the ring, and the LED lights are installed on the circuit board; the alarm lights 5 are arranged directly below the connecting pipeline 6 and correspond to the connecting pipeline 6 one by one. A text label corresponding to the gas is marked at the middle position of the alarm light 5. When the gas pressure in a certain pipeline is higher than the upper limit of the set pressure or lower than the lower limit value of the set pressure, the corresponding alarm light 5 will present corresponding light-emitting special effects, and different alarm lights 5 present different special effect colors, so as to facilitate the staff to intuitively and quickly find out the pipeline with abnormal pressure and process it in time.

[0026] As Figure 4 shown, in the electrical system 8 diagram of the present utility model, an electrical system 8 is provided inside the alarm box. Its control unit integrates a single-chip microcomputer, and the single-chip microcomputer is electrically connected to the pipeline pressure monitoring module. The pressure sensor 10 processes the monitored pressure data through the signal processing module and transmits it to the pipeline pressure monitoring module through the A / D conversion circuit. In addition, the signal is remotely transmitted to the central control platform through the communication module and the wireless transmission monitoring module for the staff to observe the pipeline pressure in real time. When the pressure is abnormal, the single-chip microcomputer controls the buzzer to emit an alarm sound, and at the same time the alarm light 5 emits light for reminder.

[0027] As Figure 5 and Figure 6 shown, for the locking component 1 of the present utility model, the locking component 1 includes a lock body 1-1 fixed to the left inner wall of the box body 7 and a lock tongue 1-2 connected to the corresponding position of the box cover 2. A limit nut is arranged outside the lock tongue 1-2, and a first spring 1-3 is arranged between the limit nut and the box cover 2; the locking component 1 further includes a lock body 1-1, and the lock body 1-1 is fixed to the left inner wall of the box body 7 by screws; a lock stop column 1-8 that can move up and down and a third spring 1-11 for pushing the lock stop column 1-8 downward are installed on the lock body 1-1. The end of the lock stop column 1-8 is a wedge-shaped block 1-10, and a lock stop fixing block 1-9 is fixed on the lock body 1-1. A through hole for the lock stop column 1-8 to pass through is provided on the lock stop fixing block 1-9, and a third spring 1-11 is arranged between the lock stop fixing block 1-9 and the wedge-shaped block 1-10; an opening groove for accommodating the lock tongue 1-2 is provided inside the lock body 1-1. The inner end of the lock tongue 1-2 is connected with an end connecting block 1-5. A sliding block 1-6 that is slidably connected to the lock tongue 1-2 is arranged outside the end connecting block 1-5. The sliding block 1-6 includes a first inclined surface on its inner side and a second inclined surface on its outer side; the inner end of the end connecting block 1-5 is a convex arc surface, and a groove that cooperates with the first inclined surface is provided on the outside. A second spring 1-7 is further arranged between the end connecting block 1-5 and the sliding block 1-6.

[0028] When locking, close the box cover 2 tightly. The lock tongue 1-2 is inserted into the opening groove of the lock body 1-1. The wedge block 1-10 at the bottom of the locking post 1-8 slides along the inner arc surface of the end connecting block 1-5. During this process, the wedge block 1-10 at the bottom of the locking post 1-8 moves upward and compresses the third spring 1-11. Finally, the wedge block 1-10 slides to the outer end of the end connecting block 1-5. At this time, the third spring 1-11 resets, pushes the locking post 1-8 downward and prevents the lock tongue 1-2 from being pulled out, and the box cover 2 is locked.

[0029] When unlocking, first press the lock tongue 1-2 inward so that it continues to move inward relative to the lock body 1-1. The wedge block 1-10 at the bottom of the locking post 1-8 slides across the first inclined surface on the inner side of the sliding block 1-6 and finally reaches the second inclined surface on the outer side. After the pressing is removed, the pre-tightening force of the first spring 1-3 is released, and the lock tongue 1-2 is pulled outwards. The wedge block 1-10 pushes the sliding block 1-6 to the left to compress the second spring 1-7, so that the sliding block 1-6 fits together with the end connecting block 1-5. The wedge block 1-10 returns to the inner side of the end connecting block 1-5 again with the help of the second inclined surface of the sliding block 1-6, and the lock body 1-1 and the lock tongue 1-2 of the locking assembly 1 can be separated to complete the unlocking.

[0030] It should be noted that for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. The scope of the present invention is defined by the claims rather than the above description.
