Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary positioning and installation devices, and particularly relates to a positioning and installation device for a temperature transmitter in a SCADA system. Background Technique

[0002] The SCADA system is the basis for the safety monitoring of pipe networks. At present, the overall SCADA coverage rate of gas enterprises is relatively low, the construction and maintenance costs are high, and there is a lack of unified construction standards. The R-SCADA in the China Resources Gas region is designed for centralized deployment, realizing cross-regional pipe network control interconnection and centralized monitoring and management, and unified technical standards for station equipment. Overall, it eliminates the investment in local system construction and operation and maintenance of member enterprises, shields network information security risks, supports the subsequent gas unified dispatching and display functions, and at the same time connects and applies gas alarms to the system to comprehensively ensure the gas use safety of users.

[0003] In the SCADA system, the access hardware includes a temperature transmitter as a temperature measuring element. Through the thermoelectric effect generated by the thermocouple, the electric signal in the circuit is processed and changed by the transmitter and then transmitted to an external display device. At present, the connecting pipe sections of the split-type temperature transmitter are redundant and need to be fixed to avoid the scattered use state, while the snap-fixing method is not conducive to the subsequent adjustment of the position of the temperature measuring probe. Therefore, it is considered necessary to fix the split-type temperature transmitter to avoid the connecting pipe from being scattered during use and also make it convenient for the subsequent adjustment of the probe position. In view of this, we propose a positioning and installation device for a temperature transmitter in a SCADA system. Content of the Utility Model

[0030] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0031] Please refer to Figure 1-6 , the present utility model details the above technical solutions through the following embodiments:

[0032] A temperature transmitter positioning and installation device is applicable to the installation of the split-type temperature transmitter 1 in the SCADA system. The split-type temperature transmitter 1 includes a connecting pipeline 13 with a digital display meter 11 and a probe 12 conductively connected at both ends. The connecting pipeline 13 is relatively long, and in most cases during use, it is redundant and lengthy. That is, after fixing the digital display meter 11 and moving the probe 12 to the specific temperature measurement position, the middle connecting pipeline will spread out. This device can realize the coiling and wire-receiving function of the connecting pipeline 13, as shown in Figure 1 and Figure 2 schematic diagrams; including:

[0033] Side fixing assembly, with the structure shown in Figure 3 , including a side fixing plate 2 with a top plate 4 and a bottom plate 6 fixedly installed at the upper and lower ends respectively. The side fixing plate 2 is detachably installed on the base through a bolt 9 to obtain a fixed position and can be installed on the equipment or the wall.

[0034] Wire winding disc 5, as shown in Figure 3In the shown structure, in this embodiment, the wire winding disc 5 is detachably installed on the side fixed plate 2 through the threaded rod 8 and is used for winding the connection pipeline 13 of the split-type temperature transmitter 1. It should be noted that the wire winding disc 5 in this embodiment cannot rotate, and the connection pipeline 13 is not wound by rotation. During the use process, the positions of the digital display meters 11 at both ends are fixed. In order to adapt to the adjustability of the probe 12, a switchable side cover plate 3 is provided in this embodiment.

[0035] The side cover plate 3, as Figure 3 shown in the structure, the upper end of the side cover plate 3 is rotatably installed on the top plate 4 and is symmetrically arranged with the side fixed plate 2; two locking units 7 are installed at the other end of the side cover plate 3 and are used for buckling on the bottom plate 6 to prevent the connection pipeline 13 from becoming loose.

[0036] It should be noted that, as Figure 3 、 Figure 5 and Figure 6 shown in the structure, in order to enable the locking unit 7 to buckle on the bottom plate 6, a convex block 61 is provided on the corresponding side of the bottom plate 6 and the side cover plate 3 in this embodiment. Card holes 601 and a first arc edge 611 are provided on both sides of the convex block 61; and the locking unit 7 includes a C-shaped fixing frame 71 provided with a first through hole 701 and a second through hole 702, and a second arc edge 711 is provided on the C-shaped fixing frame 71.

[0037] Specifically, as Figure 5 and Figure 6 shown in the structure, a sliding rod 74 is slidably installed between the first through hole 701 and the second through hole 702, and a stop block 73 is threadedly installed inside the C-shaped fixing frame 71 on the sliding rod 74. A spring 72 is sleeved between the C-shaped fixing frame 71 and the stop block 73 on the sliding rod 74. A convex ball 741 is provided at the end of the sliding rod 74, and the end of the sliding rod 74 is used for inserting into the card hole 601.

[0038] The working principle of the SCADA system temperature transmitter positioning and installation device in this embodiment is as follows: First, install the positions of the digital display meters 11 and the probes 12 according to the actual situation. The middle connection pipeline 13 is loose. Open the side cover plate 3 and wind the connection pipeline 13 around the wire winding disc 5, as Figure 1 and Figure 2 shown in the installation schematic diagram. Finally, close the side cover plate 3 so that the locking unit 7 installed below the side cover plate 3 is buckled on the bottom plate 6. That is, during the closing process, the spring 72 is compressed, and the sliding rod 74 slides backward until it aligns with the card hole 601 and then is inserted into the hole to complete the closing and fixing. At this time, the connection pipeline 13 cannot move and is prevented from becoming loose. When the position of the probe 12 needs to be adjusted, open the side cover plate 3 in the reverse direction and take out the wound connection pipeline 13.

[0039] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0041] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
