Description

Technical Field

[0001] The present application relates to the technical field of pressure transmitters, and in particular to an IO-Link pressure transmitter. Background Art

[0002] Submersible pressure transmitter (also called liquid level probe) is a special pressure transmitter used to measure static liquid level. It can be used in water tanks, wells, shafts, and deep hole environments. The pressure probe of the submersible pressure transmitter is directly immersed in the liquid, and the current liquid level, that is, the height of the liquid column above, is calculated by measuring the static pressure.

[0003] However, in the process of implementing relevant technical solutions, it was found that there are at least the following technical problems: for detection in deep wells, vertical shafts, deep holes and other environments, it is necessary to put the immersive pressure transmitter into them. However, since the terrain of these environments is relatively rugged and there is a certain height from the ground, the pressure transmitter will collide with the surrounding environment during the entry process, affecting the detection accuracy of the probe, thereby affecting the height of the measured liquid level. Summary of the invention

[0004] The present application provides an IO-Link pressure transmitter to solve the problem in the prior art that the pressure transmitter collides with the external environment due to the height and its own gravity during detection, thus affecting the accuracy of the detection result. This application not only controls the speed at which the pressure transmitter enters the liquid to be detected and adjusts its position in time, but also reduces the collision with the external environment, thereby fundamentally reducing the impact of the collision between the pressure transmitter and the external environment.

[0005] The present application provides an IO-Link pressure transmitter, including an IO-Link pressure transmitter body, and also includes: a prevention unit, which is arranged outside the IO-Link pressure transmitter body, and is used to control the IO-Link pressure transmitter body to enter the liquid to prevent the IO-Link pressure transmitter body from colliding with the outside of the environment to be detected; the prevention unit includes: a speed control component, which is connected to the IO-Link pressure transmitter body, and is used to control the speed at which the IO-Link pressure transmitter body enters the liquid of the height to be detected; a bottoming component, which is arranged between the wire-releasing component and the IO-Link pressure transmitter body, and is used to adjust the position of the IO-Link pressure transmitter body and observe the IO-Link pressure transmitter body contacting the bottom of the liquid of the height to be detected; a protection unit, which is arranged at the bottom of the IO-Link pressure transmitter body, and is used to protect the IO-Link pressure transmitter body.

[0006] Furthermore, the protection unit includes: a protection component, which is arranged outside the IO-Link pressure transmitter body; and a shock absorbing component, which is arranged between the protection component and the IO-Link pressure transmitter body, and is used to reduce the collision caused by the IO-Link pressure transmitter body entering the liquid to be detected.

[0007] Furthermore, the speed control component includes: a handle, one side of which is rotatably connected to a winding shaft; a connecting wire, which is wound on the winding shaft and the other end of which is connected to the IO-Link pressure transmitter body; and a guide ring, which is provided on one side of the handle and is used to guide the connecting wire.

[0008] Furthermore, a guide hole is provided on one side of the guide ring, and a protective surface is provided outside the guide hole.

[0009] Furthermore, the bottoming assembly includes: a connecting ring, which is sleeved on the connecting line; an extension ring, which is concentrically arranged with the connecting ring, and a plurality of groups of reinforcing ribs are arranged between the connecting ring and the extension ring; and a plurality of floating balls, which are arranged along the circumferential direction of the extension ring.

[0010] Furthermore, the protection component includes: a first connecting ring, which is arranged outside the IO-Link pressure transmitter body; and a plurality of protection plates, which are arranged along the circumferential direction of the first connecting ring.

[0011] Furthermore, the protective plate is configured to be arc-shaped, and a weight-reducing groove is provided on the protective plate.

[0012] Furthermore, the shock absorbing assembly includes: a second connecting ring, which is arranged outside the IO-Link pressure transmitter body; a plurality of support rods, which are arranged to rotate along the outside of the first connecting ring; and an elastic member, which is arranged between the support rod and the second connecting ring.

[0013] Furthermore, the support rod is higher than the IO-Link pressure transmitter body.

[0014] Furthermore, the plurality of groups of support rods form an angle with the first connecting ring, and the plurality of groups of support rods are equidistantly arranged to form a wrapping space, and surround the IO-Link pressure transmitter body.

[0015] The technical solution provided by this application has at least the following technical effects or advantages:

[0016] (1) The present application adopts a prevention unit, which uses a connecting line to slowly send the IO-Link pressure transmitter body into the liquid to be detected, and can timely adjust the entry position of the IO-Link pressure transmitter body according to the distance and position. After the IO-Link pressure transmitter body enters the liquid, the position of the IO-Link pressure transmitter body is determined according to the floating effect of the floating ball. At the same time, it can determine whether the IO-Link pressure transmitter body has touched the bottom according to whether the connecting line floats, and slowly put it in before it touches the bottom, which can reduce the damage caused to the IO-Link pressure transmitter body in a complex environment. Therefore, it effectively solves the problem that the existing IO-Link pressure transmitter body is affected by the distance and the complex environment when entering the liquid to be detected, causing collision, thereby affecting the accuracy of detection.

[0017] (2) Since the present application adopts a protection unit, the protection plate can be used to provide simple protection for the outside of the IO-Link pressure transmitter body. At the same time, the protection plate, in cooperation with the support plate, can reduce the shock caused to the IO-Link pressure transmitter body when the IO-Link pressure transmitter body collides with the outside world. Therefore, it effectively solves the problem that the existing IO-Link pressure transmitter body collides with the complex environment, affecting the accuracy of detection.

DETAILED DESCRIPTION

[0026] The embodiment of the present application discloses an IO-Link pressure transmitter. The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Embodiment 1

[0029] Reference Figure 1-Figure 2 , an IO-Link pressure transmitter, comprising an IO-Link pressure transmitter body 100, and also comprising a prevention unit 1 arranged outside the IO-Link pressure transmitter body 100 for controlling the IO-Link pressure transmitter body 100 to enter into a liquid to prevent the IO-Link pressure transmitter body 100 from colliding with the outside of the environment to be detected, the prevention unit 1 comprising a speed control component 11 connected to the IO-Link pressure transmitter body 100 for controlling the speed at which the IO-Link pressure transmitter body 100 enters the liquid of the height to be detected, and a bottoming component 12 for adjusting the position of the IO-Link pressure transmitter body 100 and observing the IO-Link pressure transmitter body 100 contacting the bottom of the liquid of the height to be detected is arranged between the wire release component and the IO-Link pressure transmitter body 100;

[0030] IO-Link uses IO-Lin transmission module technology. O-Link is a point-to-point serial communication protocol. It is a low-cost communication interface technology that integrates traditional or intelligent sensors and actuators into automation systems. With the "IO-Link" communication interface, field sensors can better adapt to the need to modify parameter settings simply and quickly, and have great flexibility in the production process, so as to better serve the detection work of IO-Link pressure transmitters. The IO-Link pressure transmitter body 100 includes a display, a connecting line 111 and a probe, which belongs to the prior art. They are collectively referred to as the IO-Link pressure transmitter body 100, wherein the probe is the most important detection part. The present invention mainly prevents and protects the probe part;

[0031] The prevention unit 1 can control the falling speed of the IO-Link pressure transmitter body 100 and can also control the speed of the IO-Link pressure transmitter body 100 when it falls into the liquid to be detected. It can reduce the impact force generated by the IO-Link pressure transmitter body 100 when it touches the bottom and reduce the risk of collision.

[0032] Reference Figure 2-Figure 4 The speed control component 11 includes a handle 10, and the handle 10 is provided with a plurality of groups of protrusions, which can play an anti-slip role. One side of the handle 10 is rotatably connected to a winding shaft 101, and the winding shaft 101 is internally driven by a worm gear. The worm is set as an active component, which can achieve a fixing effect during the release process, thereby avoiding the problem of the winding shaft 101 being off-line. A connecting wire 111 is wound around the winding shaft 101, and the other end of the connecting wire 111 is fixedly connected to the IO-Link pressure transmitter body 100. A guide ring 112 for guiding the connecting wire 111 is fixedly connected to one side of the handle 10, and a guide hole 113 is opened on one side of the guide ring 112, and a protective surface 114 is opened on the outside of the guide hole 113;

[0033] The bottoming assembly 12 includes a connecting ring 121 sleeved on the connecting line 111, and the connecting ring 121 is concentrically provided with an extension ring 122, and a plurality of groups of reinforcing ribs 123 are provided between the connecting ring 121 and the extension ring 122, and a plurality of groups of floating balls 124 are provided along the circumferential direction of the extension ring 122;

[0034] When testing liquid, the handle 10 is first held manually, and then the winding shaft 101 is rotated to lengthen the connecting wire 111 passing through the guide hole 113 and drive the IO-Link pressure transmitter body 100 at the end of the connecting wire 111 and the connecting ring 121 and the extension ring 122 sleeved on the connecting wire 111 to move downward together until they move to contact the liquid to be tested, and the floating ball 124 provided between the connecting ring 121 and the extension ring 122 can support the connecting ring 121 and the floating ball 124 to float on the liquid surface. The reinforcing ribs 123 between the connecting ring 121 and the extension ring 122 can ensure the strength of the connecting ring 121 and the extension ring 122, extend the service life, and also reduce the overall weight. At this time, the IO-Link pressure transmitter body 100 has not completely entered the bottom of the liquid. It can be judged according to the tension of the connecting line 111, and the line is continuously released until the connecting line 111 is in an untensioned state and partially floats on the liquid surface. It can be judged that the IO-Link pressure transmitter body 100 has sunk to the bottom of the liquid;

[0035] When the IO-Link pressure transmitter body 100 is in the liquid and has not reached the bottom of the liquid, the connecting line 111 can be slowly released to avoid the IO-Link pressure transmitter body 100 colliding with the bottom of the liquid due to the excessive release speed. When it is found during the release process that the positions of the extension ring 122 and the connecting ring 121 are too offset, that is, close to the inner wall of a deep well or deep hole and the position is close and rugged, the position of the connecting line 111 can be appropriately adjusted to reduce the contact between the IO-Link pressure transmitter body 100 and the inner wall of the deep well or deep hole and the position is close and rugged, thereby reducing the risk of collision.

[0036] Embodiment 2

[0037] Reference Figure 1-Figure 2 A protection unit 2 for protecting the IO-Link pressure transmitter body 100 is provided at the bottom of the IO-Link pressure transmitter body 100. The protection unit 2 includes a protection component 21 provided outside the IO-Link pressure transmitter body 100. A shock absorbing component 22 for reducing the collision caused by the IO-Link pressure transmitter body 100 entering the liquid to be detected is provided between the protection component 21 and the IO-Link pressure transmitter body 100.

[0038] Reference Figure 5-Figure 7 The protection component 21 includes a first connecting ring 211 disposed outside the IO-Link pressure transmitter body 100, and a plurality of groups of protection plates 212 are fixedly connected along the circumferential direction of the first connecting ring 211. The protection plates 212 are configured to be arc-shaped, and a weight-reducing groove 213 is provided on the protection plates 212;

[0039] The shock absorbing assembly 22 includes a second connecting ring 221 disposed outside the IO-Link pressure transmitter body 100, and a plurality of support rods 222 are provided along the outer rotation of the first connecting ring 211. An elastic member 223 is fixedly connected between the support rods 222 and the second connecting ring 221. The elastic member 223 is preferably an arc spring. An angle is formed between the plurality of support rods 222 and the first connecting ring 211, and the plurality of support rods 222 are equidistantly arranged to form a wrapping space and surround the IO-Link pressure transmitter body 100. The height of the support rods 222 is longer than the IO-Link pressure transmitter body 100, and the IO-Link pressure transmitter body 100 can be wrapped without direct contact with the rugged environment outside.

[0040] The top of the protective plate 212 is fixedly connected to the connecting line 111. The protective plate 212 can increase the diameter of the IO-Link pressure transmitter body 100. During the slow movement in a complex environment, the contact end of the IO-Link pressure transmitter body 100 can be reduced from directly contacting the complex environment, thereby reducing the possibility of collision.

[0041] When direct contact with a complex environment is unavoidable, the support rod 222 and the elastic member 223 can be set so that during the collision, the support rod 222 can be rotated to compress the elastic member 223, thereby reducing the direct collision with the IO-Link pressure transmitter body 100 and playing a protective role.

[0042] How this application works:

[0043] The IO-Link pressure transmitter body 100 is slowly fed into the liquid to be detected by unwinding the winding shaft 101 so that the connecting wire 111 can be adjusted in time according to the distance and position. After the IO-Link pressure transmitter body 100 enters the liquid, the position of the IO-Link pressure transmitter body 100 is determined according to the floating effect of the floating ball 124. At the same time, it can be determined whether the IO-Link pressure transmitter body 100 has touched the bottom according to whether the connecting wire 111 floats, and the IO-Link pressure transmitter body 100 is slowly inserted before touching the bottom, which can reduce the damage caused to the IO-Link pressure transmitter body 100 in a complex environment.

[0044] During the placement of the IO-Link pressure transmitter body 100, the protective plate 212 can also be used to provide simple protection for it. With the cooperation of the support plate, the protective plate 212 can reduce the shock caused to the IO-Link pressure transmitter body 100 when it collides with the outside world, so that the IO-Link pressure transmitter body 100 can be easily operated and can effectively play a protective role.

[0045] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0046] What has been described above is only a preferred specific implementation manner of the embodiments of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
