Description

Technical Field

[0001] The invention relates to the technical field of instrument protection, and in particular to a protective device for an outdoor pipeline flow meter. Background Art

[0002] Outdoor pipeline flowmeters play a vital role in many industrial fields and municipal infrastructure construction. For example, in the petrochemical industry, they are used to accurately measure the flow of crude oil and various chemical raw materials during pipeline transmission, so as to achieve reasonable production allocation and monitoring; in urban water supply and drainage systems, they can accurately measure the flow of water, providing a basis for water resource management and water fee collection.

[0003] However, since it is installed in an outdoor pipeline environment, it inevitably faces many severe challenges. First, the outdoor environment is changeable, and severe weather conditions such as heavy rain, heavy snow, strong winds, and scorching sun often occur. Heavy rain and heavy snow may cause water to enter the flow meter and cause malfunctions, affecting its normal measurement function or even causing permanent damage; strong winds may cause the flow meter to be impacted by external forces, causing its shell to deform and internal components to loosen. Scorching sun exposure will cause the flow meter to be in a high temperature environment for a long time, accelerating the aging of its shell and internal electronic components and shortening its service life.

[0004] Traditional protection methods mostly use the flowmeter's own plastic cover to cover the electronic components, trying to block some rain, dust, etc. However, this protection method is too simple. On the one hand, its waterproof performance is limited. In heavy rainfall such as rainstorms, rainwater will penetrate through the gaps at the cable interface, and it is impossible to truly achieve effective waterproof protection for the flowmeter. On the other hand, the protection against external impact is insufficient. When the plastic cover is hit by a large external force, it is easy to deform or even break, and it is difficult to effectively disperse the impact force. It cannot well protect the precision components inside the flowmeter from damage. Secondly, it is not easy to disassemble and assemble, and maintenance is cumbersome.

[0005] Based on this, the present invention designs an outdoor pipeline flow meter protection device to solve the above problems. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an outdoor pipeline flow meter protection device.

[0007] The technical solution adopted to solve the above technical problems is:

[0008] An outdoor pipeline flow meter protection device comprises a flow meter, a mounting assembly for protecting the flow meter is mounted on the flow meter, a buffering waterproof assembly for buffering and preventing water from entering the flow meter is mounted in the mounting assembly, and a quick-release locking assembly for quick disassembly and assembly is mounted on the mounting assembly;

[0009] Also included is a cable, the cable is electrically connected to the flow meter, and the cable is connected to the mounting assembly and the buffer waterproof assembly;

[0010] It also includes a second roller, the second roller is connected to the mounting assembly, and the cable is rollingly connected to the second roller;

[0011] Also included is a drainage hole, wherein the drainage hole is connected to the mounting assembly;

[0012] The buffer-type waterproof component comprises a mounting frame and a buffer component. The mounting frame is connected to the mounting component, and the buffer component is connected to the mounting frame and a cable.

[0013] Through the above technical scheme, the electronic component part of the flow meter can be protected by installing the assembly, which can effectively prevent the electronic components from being damaged by collision, and can also prevent them from being eroded by rain, thereby ensuring that the electronic components are always in good operating condition. The buffer assembly is installed through the mounting frame, and the cable enters from the mounting assembly and bypasses the buffer assembly to connect the flow meter, so that the cable is bent at the buffer assembly. Rainwater will drip from the buffer assembly and will not flow into the flow meter, thereby playing a waterproof protection role for the flow meter and effectively ensuring that its performance is not affected by rain. At the same time, the buffer assembly can buffer the cable. When the cable is pulled, the buffer assembly shrinks to buffer the cable, thereby avoiding damage to the flow meter interface caused by the cable being pulled, and maintaining the integrity and stability of the entire connection structure. At the same time, a quick-release locking assembly is used to divide the installation assembly into a movable part and a fixed part. The movable part has the characteristics of quick disassembly and assembly, which greatly facilitates the subsequent inspection and maintenance of related components, effectively reduces maintenance costs and time costs, and improves the maintainability of the entire equipment system for easy inspection and maintenance.

[0014] Furthermore, the mounting assembly includes a mounting base assembly and a protective shell, the mounting base assembly is connected to the flow meter, the mounting base assembly is connected to the protective shell, the upper end surface of the mounting frame is fixedly connected to the inner top surface of the protective shell, the protective shell is connected to the quick-release locking assembly, and the second roller is rotatably installed on the upper end of the right side panel of the protective shell.

[0015] Through the above technical solution, the protective shell can serve as a movable part to protect the electronic components of the flow meter, which can effectively prevent the electronic components from being damaged due to collision, and can also prevent them from being corroded by rain. The cable passes through the second roller to avoid direct contact with the installation components to cause damage to the cable.

[0016] Furthermore, the mounting base assembly is symmetrically arranged in two groups front and back, and the mounting base assembly includes a clamp body and a mounting plate. The lower surface of the inner end of the mounting plate is fixedly connected to the upper end surface of the clamp body. The two groups of the clamp bodies are fastened to the flow meter by bolts, and the lower end surface of the protective shell is fit-connected to the upper end surfaces of the two groups of mounting plates.

[0017] Through the above technical solution, two sets of clamp bodies are fixed to the flow meter by bolts, and the mounting plate at the upper end of the clamp body is combined with the protective shell as a movable part to form a closed structure to protect the flow meter.

[0018] Furthermore, a plurality of drainage holes are provided on the right side of the upper end surface of the mounting plate.

[0019] Through the above technical solution, water dripping from the buffer component is discharged through the drainage hole, thereby avoiding the occurrence of water accumulation and corrosion.

[0020] Furthermore, the buffer assembly includes a sliding rod, a first spring, a fixed frame and a first roller, the sliding rod and the first spring are arranged in two groups front to back, the upper end of the sliding rod is slidably connected to the lower end of the mounting frame, the lower end surface of the sliding rod is fixedly connected to the upper end surface of the fixing frame, the first spring is sleeved on the outside of the sliding rod, the upper end of the first spring is fixedly connected to the lower end surface of the mounting frame, the lower end of the first spring is fixedly connected to the upper end surface of the fixing frame, the first roller is rotatably installed on the inner side wall of the fixing frame, and the cable is rotatably connected to the first roller.

[0021] Through the above technical solution, based on the position of the second roller being higher than that of the first roller, and the position of the first roller being lower than that of the interface on the flow meter, when the cable passes through the second roller and then bypasses the first roller and is connected to the flow meter, the cable will form a bend under the first roller, and rainwater will drip from the bend and be discharged through the drainage hole, thereby playing a waterproof protection role for the flow meter and effectively ensuring that its performance is not affected by rainwater. When the cable is pulled, the first roller will drive the fixing frame, and the fixing frame will drive the slide rod to slide on the mounting frame. At the same time, the fixing frame compresses the first spring, so that the cable has a certain buffer space and will not cause damage to the interface of the flow meter, thereby maintaining the integrity and stability of the entire connection structure.

[0022] Furthermore, the quick-release locking assembly is symmetrically arranged in two groups front and back, and the quick-release locking assembly includes a mounting shell, a push rod, a pin rod and a second spring. The upper end surface of the mounting shell is fixedly connected to the lower end surface of the mounting plate, the push rod is limitedly slidably connected to the mounting shell, the pin rod is plugged into the mounting shell, and the push rod is used in conjunction with the bayonet on the pin rod. One end of the second spring is fixedly connected to the inner side surface of the push rod, and the other end of the second spring is fixedly connected to the inner end surface of the mounting shell. The upper end surface of the pin rod is fixedly connected to the lower end surface of the mounting ear at the inner end of the protective shell.

[0023] Through the above technical scheme, the spring force of the second spring can be used to drive the push rod to clamp the pin rod, and the unlocking is completed by pushing the push rod inward to release the clamping limit of the pin rod, thereby realizing the characteristic of quick disassembly and assembly of the protective shell, greatly facilitating the subsequent inspection and maintenance of related components, effectively reducing maintenance costs and time costs, and improving the maintainability of the entire equipment system for easy inspection and maintenance.

[0024] The beneficial effects of the present invention are as follows: (1) the electronic component part of the flow meter can be protected by the installation component, which can effectively prevent the electronic components from being damaged by collision, and can also prevent them from being eroded by rain, thereby ensuring that the electronic components are always in good operating condition; (2) the buffer component is installed through the mounting frame, and the cable enters from the mounting component and bypasses the buffer component to connect to the flow meter, so that the cable is bent at the buffer component. Rainwater will drip from the buffer component and will not flow into the flow meter, which plays a waterproof protection role for the flow meter and effectively ensures that its performance is not affected by rain. At the same time, the buffer component can buffer the cable. When the cable is pulled, the buffer component shrinks to buffer and protect the cable, avoiding damage to the flow meter interface caused by the cable being pulled, and maintaining the integrity and stability of the entire connection structure; (3) the quick-release locking component is used to divide the installation component into a movable part and a fixed part. The movable part has the characteristic of quick disassembly and assembly, which greatly facilitates the subsequent inspection and maintenance of related components, effectively reduces maintenance costs and time costs, and improves the maintainability of the entire equipment system for easy inspection and maintenance.
