[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0029] Reference Figure 1-5A pressure measuring device for fire extinguisher production includes a box body 1, an electric cylinder 45, an air supply pump 44 and a support frame 22. A rectangular opening is opened on both sides of the box body 1. Support legs 11 are fixedly installed at the four corners of the bottom of the box body 1. Conveying rollers 21 are rotatably installed on both sides of the box body 1. Four conveying pipes 422 are rotatably installed on the support frame 22. The two conveying rollers 21 and the four conveying rollers 23 are connected to the same conveyor belt 2. A conveying motor 24 is fixedly installed on the support frame 22. The output shaft of the conveying motor 24 is axially fixedly connected to one of the conveying rollers 23, which can convey the fire extinguisher tank. In order to ensure the friction between the conveying roller 23 and the conveyor belt 2, thereby achieving stable transmission and conveying, The angle between the conveyor roller 23 axially fixedly connected to the output shaft of the motor 24 and the conveyor belt 2 is greater than 120 degrees. A guide opening is provided on each of the four support legs 11. The same guide rod 31 is fixedly installed on the top inner wall and the bottom inner wall of the guide opening. The support frame 22 is slidably connected to the four guide rods 31. Springs 3 are fixedly installed on the top inner walls of the four guide openings. The bottom ends of the four springs 3 are fixedly installed on the top side of the support frame 22. The tensioning adjustment of the conveyor belt 2 can be achieved when the lifting plate 4 controls the fire extinguisher tank to be pressure-measured to sink into the water, which can prevent the conveyor belt 2 from being over-stretched and ensure that the conveyor belt 2 will not be loose. The electric cylinder 1 45 is fixedly installed on the top inner wall of the box body 1, and the lifting plate 4 is slidably installed on the front and rear inner walls of the box body 1. The pressure measuring assembly is arranged on the lifting plate 4, wherein the pressure measuring assembly includes multiple branch pipes 41, multiple pressure gauges 411, a delivery pipe 42, multiple sealing plugs 412 and a connecting hose 43. The multiple branch pipes 41 are arranged in parallel with each other and fixedly installed on the lifting plate 4. The multiple pressure gauges 411 are fixedly installed on the corresponding branch pipes 41. The delivery pipe 42 is connected to the top of the multiple branch pipes 41. The delivery pipe 42 is connected to the air outlet of the air supply pump 44 through the connecting hose 43. The multiple sealing plugs 412 are fixedly installed on the bottom side of the lifting plate 4 and are sleeved on the outside of the branch pipe 41. The box body 1 is fixedly installed with four guide columns 47 arranged in parallel with each other, and the four guide columns 47 are slidably installed with the same multiple The porous float plate 46 and the top side of the porous float plate 46 are in contact with the conveyor belt 2, and the lifting plate 4 is slidably connected to the four guide columns 47, which can provide a support effect for the conveyor belt 2 to avoid the phenomenon of tipping over during the transportation of the fire extinguisher tank through the conveyor belt 2. At the same time, it does not affect the porous float plate 46 sinking into the water with the fire extinguisher tank, and can realize the self-reset of the porous float plate 46 after the fire extinguisher tank moves above the water surface. In addition, it can provide a guiding effect for the lifting plate 4 with the cooperation of the four guide columns 47. Electric cylinders 2 51 are fixedly installed on the inner walls of the front and rear sides of the box body 1, and the working ends of the two electric cylinders 2 51 are fixedly installed with clamps 5. The two clamps 5 are arranged parallel to each other and can clamp and fix the fire extinguisher tank after the pressure measurement is completed.This facilitates the detachment of the sealing plug 412 from the fire extinguisher tank during its upward movement.

[0030] In this embodiment, in order to ensure the stable movement of the splint 5 under the control of the electric cylinder 2 51, two sliding rods are slidably installed on the front and rear sides of the box body 1. The four sliding rods extend into the box body 1 and are fixedly connected to the corresponding splints 5 respectively.

[0031] In this embodiment, in order to ensure a stable connection between the electric cylinder 45 and the lifting plate 4, while avoiding affecting the installation of the conveying pipe 42 and the branch pipe 41, and in order to ensure the installation stability of the conveying roller 21, the working end of the electric cylinder 45 is fixedly installed with a connecting frame 451, and the connecting frame 451 is fixedly installed in the center position of the top side of the lifting plate 4, and two support plates are fixedly installed on both sides of the box body 1, and the two conveying rollers 21 are rotatably installed on the corresponding two support plates.

[0032] In this embodiment, in order to facilitate the operator to observe the pressure gauge 411 and the liquid level height in the box body 1, an observation port is opened on the front side of the box body 1, and a transparent glass plate is sealed and fixedly installed in the observation port.

[0033] The circuits, electronic components and module structures involved all use existing technologies, which can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software, circuits and methods.

[0034] Working principle: When in use, first turn on the power supply, and place the fire extinguisher tanks that need to be pressure measured on the conveyor belt 2 at equal intervals. The spacing between adjacent fire extinguisher tanks is kept the same as the spacing between two adjacent sealing plugs 412. Then start the conveying motor 24, so that the conveyor belt 2 drives the fire extinguisher tank to move to the position below the lifting plate 4 and is located directly below the corresponding sealing plug 412. During this process, with the support of the porous floating plate 46, the stable transportation of the fire extinguisher tank on the conveyor belt 2 can be guaranteed to avoid it from tipping over. Subsequently, the lifting plate 4 is controlled to descend by the electric cylinder 45, so that the sealing plug 412 is inserted into the bottle mouth of the fire extinguisher tank. As the lifting plate 4 continues to descend, the fire extinguisher tank and the lifting plate 4 can be completely sunk into the water and the porous floating plate 46 can abut against the bottom inner wall of the box body 1. During this process, since the conveyor belt 2 follows the fire extinguisher tank to move downward, the part of the conveyor belt 2 located below the box body 1 will move upward and compress the spring 3, so that the conveyor belt 2 can adjust the tension by itself.

[0035] Then the air supply pump 44 starts to work, and pressurizes the multiple fire extinguisher tanks synchronously by connecting the hose 43 and the delivery pipe 42 and cooperating with multiple branch pipes 41. At the same time, multiple pressure gauges 411 monitor the pressure in the tank in real time. When the pressure in the tank reaches a predetermined value, it maintains a stable pressure state, so that the multiple fire extinguisher tanks can be pressure-measured synchronously. After the pressure measurement is completed, the lifting plate 4 is controlled to move upward by the electric cylinder 1 45, so that the fire extinguisher tank can be brought out of the water surface, and the porous floating plate 46 floats and resets under the action of buoyancy, and the conveyor belt 2 can also be reset under the action of the reaction force of the spring 3. Then, the plywood 5 is controlled by the electric cylinder 2 51 to clamp the fire extinguisher tank. As the lifting plate 4 continues to move upward, the sealing plug 412 can be pulled out of the fire extinguisher tank. After the sealing plug 412 is pulled out, the control plywood 5 and the fire extinguisher tank are released from the clamping state, and then the fire extinguisher hanging after pressure measurement is transported out of the box 1 through the conveyor belt 2.

[0036] The above describes in detail the pressure measuring device for fire extinguisher production provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
