Description

Technical Field

[0001] This utility model belongs to the field of chemical production safety technology, and in particular relates to a pressure safety detection device for chemical tower equipment. Background Technology

[0002] Pressure safety monitoring devices for chemical tower equipment are crucial for ensuring the safety of chemical production. By monitoring pressure changes, they can promptly detect abnormalities and take corresponding safety measures, effectively preventing safety accidents caused by abnormal pressure. These devices typically utilize pressure detection equipment, which usually includes a pressure detector. The working principle of this detector is to convert pressure into an electrical signal for transmission and display. It uses mechanical and electrical components to convert the measured pressure into electrical quantities (such as voltage, current, frequency, etc.) for measurement. Publication number CN202836854U provides a pressure detection device that addresses the lack of a dedicated pressure detection device for interior chambers. The feature of this invention is that a U-shaped pressure gauge is fixed inside a pressure detection cabinet, and sampling hoses are installed at both ends of the U-shaped pressure gauge. The sampling port of the internal pressure detection sampling hose is located inside the chamber, while the external pressure detection sampling hose is fixed to one end of an external pressure acquisition tube that passes through the chamber wall. This invention accurately measures the pressure inside and outside the well chamber in complex underground environments, providing information for refugees and enabling them to take appropriate measures based on specific needs. It also features easy operation, simple structure, reduced cost, and high safety.

[0003] However, existing technologies have some problems: existing chemical tower pressure testing devices are usually connected to the testing pipes of chemical towers through connectors. However, the testing pipes of different chemical towers have different diameters. Therefore, when testing different chemical towers, the connectors need to be replaced repeatedly, and the sealing needs to be ensured after each replacement. The process is quite cumbersome. Therefore, we propose a pressure safety testing device for chemical tower equipment. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a pressure safety detection device for chemical tower equipment. Through fixing components and sealing components, the pressure detection device can be connected to different chemical tower detection pipelines without the need for frequent replacement of joints.

[0005] This utility model is implemented as follows: it includes a machine body and a connecting cylinder. A drum is rotatably connected inside the machine body. A drive assembly is provided on the machine body to drive the drum to rotate. A vent pipe is wound on the drum. A detector is fixedly connected to the machine body. One end of the vent pipe is connected to the detector, and the other end of the vent pipe is connected to the connecting cylinder. A fixing assembly is provided on one side of the connecting cylinder, and a sealing assembly is provided inside the connecting cylinder.

[0006] Optionally, the drive assembly includes a rotating shaft, a cavity is provided in the body of the machine, the rotating shaft is rotatably connected in the cavity, the drum is fixedly connected to the rotating shaft, and a handle is fixedly connected to one end of the rotating shaft.

[0007] Optionally, the fixing component includes a fixing ring, which is rotatably connected to the connecting cylinder. The connecting cylinder has a slide rail, and a fixing block is slidably connected within the slide rail.

[0008] Optionally, a driving block is fixedly connected to the fixed ring, and an arc-shaped groove is provided on the fixed block. The driving block is slidably connected in the arc-shaped groove, and the driving block is used to drive the fixed block to slide in the slide of the connecting cylinder.

[0009] Optionally, a groove is provided in the fixed ring, and a drive cylinder is slidably connected in the groove. The drive cylinder is movably connected to the connecting cylinder, and a drive knob is fixedly connected to the drive cylinder. The drive knob is threadedly connected to the connecting cylinder.

[0010] Optionally, the sealing assembly includes a sealing ball, which is movably connected inside the connecting cylinder, and a vent hole is provided in the center of the sealing ball.

[0011] Optionally, a cylinder cover is fixedly connected to the sealing ball, the cylinder cover is threaded into the connecting cylinder, the cylinder cover has a through hole, and the vent pipe is fixedly connected to the inner wall of the through hole.

[0012] Optionally, a caster wheel is fixedly connected to the lower end of the machine body, and a push rod is fixedly connected to one side of the machine body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a fixing component. When using this device to detect the pressure inside the chemical tower, the device can be connected to the detection pipeline on the chemical tower through the fixing component. At the same time, by adjusting the fixing component, the device can be connected to detection pipelines of different diameters. Then, the device is sealed by the sealing component. There is no need to constantly replace the joints and retest the sealing performance, making it more convenient to use.

[0015] 2. This utility model can rotate a drive knob, which in turn drives a drive cylinder to rotate, which in turn drives a fixed ring to rotate, thereby causing a drive block on the fixed ring to rotate. The drive block then drives the fixed block to slide in a slide rail on the connecting cylinder through an arc groove on the fixed block, thereby causing the fixed block to move towards the center. This allows the connecting cylinder to be fixed to the detection pipe of the chemical tower by the fixed block. At the same time, rotating the drive knob can change the moving distance of the fixed block, so that this device can be connected to detection pipes of different diameters on different chemical towers.

[0016] 3. Equipped with a drive assembly, when using the pressure detection device to test the chemical tower, the vent pipe can be pulled, causing the vent pipe to drive the drum and shaft to rotate within the cavity of the machine body. This allows the drum to release the vent pipe wound on it, ensuring that the length of the vent pipe is sufficient to connect the device to the chemical tower. After the test is completed, the handle can be turned to drive the shaft to rotate, which in turn drives the drum to rotate, allowing the drum to retract the vent pipe, reducing the space occupied by the vent pipe and preventing it from becoming entangled.

[0017] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0024] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0025] like Figures 1 to 5 As shown in the figure, the pressure safety detection device for chemical tower equipment provided in this embodiment of the utility model includes a body 1 and a connecting cylinder 2. The body 1 is made of stainless steel and its main function is to support the entire device and protect its internal components.

[0026] Furthermore, a drum 3 is rotatably connected inside the machine body 1, and a drive assembly 4 is provided on the machine body 1 to drive the drum 3 to rotate.

[0027] Furthermore, the drive assembly 4 includes a rotating shaft 401, a cavity is provided inside the body 1, the rotating shaft 401 is rotatably connected in the cavity, the drum 3 is fixedly connected to the rotating shaft 401, and a handle 402 is fixedly connected to one end of the rotating shaft 401.

[0028] Specifically, when using the pressure testing device to test the chemical tower, the vent pipe 5 can be pulled, causing the vent pipe 5 to drive the drum 3 and the rotating shaft 401 to rotate within the cavity of the machine body 1. This allows the drum 3 to release the vent pipe 5 wound on it, ensuring that the length of the vent pipe 5 is sufficient to connect the device to the chemical tower. After the test is completed, the rotating handle 402 can be turned to drive the rotating shaft 401 to rotate. The rotating shaft 401 then drives the drum 3 to rotate, allowing the drum 3 to retract the vent pipe 5, reducing the space occupied by the vent pipe 5 and preventing it from becoming entangled.

[0029] Furthermore, a vent pipe 5 is wound around the drum 3. The vent pipe 5 is a steel wire reinforced hose. This material adds a steel wire reinforcement layer to the nylon resin or other base materials, which significantly improves the pressure resistance and tensile strength of the connecting pipe. The steel wire reinforced hose can withstand higher working pressure and is not easy to deform or break, making it particularly suitable for high-pressure testing.

[0030] Furthermore, a detector 10 is fixedly connected to the body 1, and one end of the vent pipe 5 is connected to the detector 10. The detector 10 is an electric pressure detector 10, which is an instrument that can convert pressure into an electrical signal for transmission and display. It is an instrument that converts the measured pressure into electrical quantity (such as voltage, current, frequency, etc.) through mechanical and electrical components for measurement. The electric pressure detector 10 has a wide measurement range, small allowable error, can transmit signals over long distances, and can be used in conjunction with industrial control systems. The above-mentioned pressure detector 10 is a mature existing technology, which should be well understood by those skilled in the art, so it will not be described in detail here.

[0031] Furthermore, the other end of the vent pipe 5 is connected to the connecting cylinder 2, and a fixing component 6 is provided on one side of the connecting cylinder 2.

[0032] Specifically, the fixing component 6 includes a fixing ring 601, which is rotatably connected to the connecting cylinder 2. The connecting cylinder 2 has a slide rail, and a fixing block 602 is slidably connected in the slide rail.

[0033] Furthermore, a drive block 603 is fixedly connected to the fixed ring 601, and an arc-shaped groove is provided on the fixed block 602. The drive block 603 is slidably connected in the arc-shaped groove, and the drive block 603 is used to drive the fixed block 602 to slide in the slide of the connecting cylinder 2.

[0034] Furthermore, a groove is provided inside the fixing ring 601, and a drive cylinder 604 is slidably connected inside the groove. The drive cylinder 604 is movably connected to the connecting cylinder 2, and a drive knob 605 is fixedly connected to the drive cylinder 604. The drive knob 605 is threadedly connected to the connecting cylinder 2.

[0035] Specifically, rotating the drive knob 605 causes the drive cylinder 604 to rotate, which in turn causes the fixed ring 601 to rotate. This causes the drive block 603 on the fixed ring 601 to rotate. The drive block 603 then drives the fixed block 602 to slide in the slide rail on the connecting cylinder 2 through the arc groove on the fixed block 602. This causes the fixed block 602 to move towards the center, thereby fixing the connecting cylinder 2 to the detection pipeline of the chemical tower through the fixed block 602. At the same time, rotating the drive knob 605 can change the moving distance of the fixed block 602, so that this device can be connected to detection pipelines of different diameters on different chemical towers.

[0036] Furthermore, a sealing assembly 7 is provided inside the connecting cylinder 2. The sealing assembly 7 includes a sealing ball 701, which is movably connected inside the connecting cylinder 2. A vent hole is provided in the middle of the sealing ball 701. The sealing ball 701 is made of rubber, which has good elasticity and wear resistance, so it can effectively seal the device.

[0037] Furthermore, a cylinder cover 702 is fixedly connected to the sealing ball 701. The cylinder cover 702 is threaded into the connecting cylinder 2. A through hole is opened on the cylinder cover 702, and the vent pipe 5 is fixedly connected to the inner wall of the through hole.

[0038] Specifically, after rotating the cylinder cover 702, the cylinder cover 702 moves into the connecting cylinder 2 through the thread, thereby causing the sealing ball 701 to move towards the detection pipe of the chemical tower, thereby sealing the detection pipe with the sealing ball 701, so that the pressure inside the chemical tower can only be discharged through the vent on the sealing ball 701, thus making the device accurately detect the pressure inside the chemical tower.

[0039] Furthermore, a caster wheel 8 is fixedly connected to the lower end of the body 1, and a push rod 9 is fixedly connected to one side of the body 1. The main function of the caster wheel 8 is to allow the pressure detection device to be pushed by the push rod 9, thereby facilitating the movement of the device and making it convenient to detect chemical towers at different locations.

[0040] The working principle of this utility model is as follows:

[0041] This utility model is equipped with a fixing component 6. When using this device to detect the pressure inside the chemical tower, the device can be connected to the detection pipeline on the chemical tower through the fixing component 6. At the same time, by adjusting the fixing component 6, the device can be connected to detection pipelines of different diameters. Then, the device is sealed by the sealing component 7. There is no need to constantly replace the joints and retest the sealing performance, making it more convenient to use.

[0042] This invention allows the drive knob 605 to rotate, which in turn drives the drive cylinder 604 to rotate. The rotation of the drive cylinder 604 then drives the fixed ring 601 to rotate, thereby causing the drive block 603 on the fixed ring 601 to rotate. The drive block 603 then drives the fixed block 602 to slide within the slide rail on the connecting cylinder 2 through the arc groove on the fixed block 602, thus moving the fixed block 602 towards the center. This allows the connecting cylinder 2 to be fixed to the detection pipeline of the chemical tower by the fixed block 602. At the same time, rotating the drive knob 605 can change the moving distance of the fixed block 602, so that this device can be connected to detection pipelines of different diameters on different chemical towers.

[0043] Equipped with a drive assembly 4, when the pressure detection device is used to test the chemical tower, the vent pipe 5 can be pulled, causing the vent pipe 5 to drive the drum 3 and the rotating shaft 401 to rotate within the cavity of the machine body 1. This allows the drum 3 to release the vent pipe 5 wound on it, ensuring that the length of the vent pipe 5 is sufficient to connect the device to the chemical tower. After the test is completed, the rotating handle 402 can be turned to drive the rotating shaft 401 to rotate. The rotation of the rotating shaft 401 then drives the drum 3 to rotate, allowing the drum 3 to retract the vent pipe 5, reducing the space occupied by the vent pipe 5 and preventing it from becoming entangled.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
