[0029] Since the instrument device 210 needs to be connected to a cable (not shown) for pressure measurement, and in the related art, the cable routing is random and not convenient for connecting to the instrument device 210. In this embodiment, the ends of the cables are integrated through the cable integration structure 300, which changes the original cable inlet mode, improves the aesthetics of the entire instrument support device, reduces the use of cable pipes, and facilitates cable termination. The cable support is welded to the fixed frame 110, and the cable integration structure 300 is fixed to the cable support. The cable integration structure 300 is provided with a cable accommodation space 301 for accommodating the cables.
[0030] Continue to refer to Figure 1 , the cable integration structure 300 is of a hollow structure, and the hollow part is the cable accommodation space 301, and the ends of the cables can be integrated into this space.
[0031] Furthermore, the cable integration structure 300 is in an L shape and specifically includes a first integration part 310 and a second integration part 320. The first integration part 310 is perpendicular to the second integration part 320, and the cable accommodation space 301 of the first integration part 310 is communicated with the cable accommodation space 301 of the second integration part 320, which is convenient for cable routing.
[0032] The cable support includes a first cable support rod 122a and a second cable support rod 122b.

The connection mode between the first integration part 310 and the first cable support rod 122a and the second cable support rod 122b can be selected as bolt connection to realize the detachable function of the cable integration structure 300.
[0033] The first cable support rod 122a and the second cable support rod 122b can be selected as galvanized angle steels with a specification of ∠63×6mm.
[0034] The first integration part 310 is provided with at least one through hole (not shown) communicated with the cable accommodation space 301. The cables located in the cable accommodation space 301 pass through the through holes and are connected to the instrument device 210. The number of through holes is adapted to the number of instrument devices 210. Such as Figure 1In the illustrated embodiment, the number of instrument devices 210 is four, so there are at least four through holes, which correspond to the instrument devices 210 one by one.
[0035] In the related art, the technical solution for instrument sewage discharge is that the instrument sewage is summarized to the sewage discharge main pipe of the instrument rack and led to the nearby pipeline sewage discharge main pipe or sewage ditch through the lower water outlet. When operating and maintaining, it is necessary to check the sewage discharge situation. In the existing construction process, the installed sewage discharge main pipe cannot achieve real-time viewing. It is necessary to remove the sewage discharge main pipe to observe, and a temporary sewage receiving bucket needs to be placed below.
[0036] In one embodiment, the instrument support device further includes a sewage collection structure 400. The sewage collection structure 400 is used to collect the fluid medium in the sewage discharge branch 223. The sewage collection structure 400 can visually observe the state of the fluid medium containing dirt during the later operation.

The sewage collection structure 400 is detachably connected to the first sewage collection support rod 123a and the second sewage collection support rod 123b.
[0038] The first sewage collection support rod 123a and the second sewage collection support rod 123b can be optionally galvanized angle steel with a specification of ∠63×6mm.
[0039] The sewage collection structure 400 is provided with a dirt receiving space 401. The sewage collection structure 400 is connected to the sewage discharge branch 223 and is located downstream of the sewage discharge valve 225 on the sewage discharge branch 223. The sewage discharge branch 223 is communicated with the dirt receiving space 401 so that the fluid medium in the instrument branch pipe 221 can enter the dirt receiving space 401.
[0040] The sewage collection structure 400 includes a sewage collection structure main body 410 and an opening / closing part 420. The sewage collection structure main body 410 encloses to form the dirt receiving space 401. The opening / closing part 420 is movably provided on the sewage collection structure main body 410. As Figure 1 shown, the opening / closing part 420 is provided on the top surface of the sewage collection structure main body 410 and can be opened upward. When the opening / closing part 420 is opened, at least part of the dirt receiving space 401 is communicated with the outside, and the internal situation of the dirt receiving space 401 can be observed by opening the opening / closing part 420, which is convenient for maintenance and checking the sewage discharge situation.
[0041] The overall shape of the sewage collection structure 400 can be selected as tubular, square columnar, the shape shown in Figure 1 and other shapes.
[0042] The sewage collection structure 400 can be made of stainless steel, and the opening and closing part 420 can be made of stainless steel plate.
[0043] Since the sewage discharge branch 223 is located downstream of the instrument branch pipe 221 and is located below the instrument device 210 in terms of spatial position, the first sewage collection support rod 123a is located below the first cable support rod 122a, and the second sewage collection support rod 123b is located below the second cable support rod 122b.
[0044] At least one sewage collection hole communicating with the sewage collection space 401 is opened on the top surface of the sewage collection structure 400. The sewage discharge branch 223 passes through the sewage collection hole and is connected to the sewage collection space 401.
[0045] Combined with Figures 1 to 3 , a sewage discharge pipe 430 communicating with the sewage collection space 401 is opened on the bottom surface of the sewage collection structure 400. The sewage discharge pipe 430 can regularly discharge the sewage in the sewage collection space 401 in a centralized manner.
[0046] As Figure 1 shown, the fixed frame 110 includes opposite first mounting surfaces 110a and second mounting surfaces 110b. The instrument device 210 is mounted on the first mounting surface 110a, that is, the instrument device 210 is mounted on the front surface of the fixed frame 110. The cable support member and the sewage collection support member are welded to the second mounting surface 110b, that is, the back surface of the fixed frame 110. Furthermore, the cable integration structure 300 and the sewage collection structure 400 are mounted on the second mounting surface 110b, so that it is convenient for cable inlet and outlet, and it is also convenient to check the internal situation of the sewage collection space 401.
[0047] The instrument support device of the present utility model can be prefabricated before construction, and the width of the instrument support 100, that is, the distance between the two columns 111, can be adjusted according to the number of instrument devices 210 arranged centrally.
[0048] The instrument support device of the present utility model combines the instrument support 100, the instrument assembly 200, the cable integration structure 300 and the sewage collection structure 400, and prefabricates and welds the instrument assembly 200, the cable integration structure 300 and the sewage collection structure 400 on the instrument support 100 in advance, so that the installation of the instrument rack is no longer a simple bracket installation, and the instrument pipe can be prefabricated in advance, which can reduce the number of instrument pipe welds during the peak construction period, reduce the input of personnel and time during the peak period, improve the construction efficiency, optimize the existing construction process, and modularize the instrument support device can better centrally arrange the instrument devices 210, and can better achieve the control of quality and safety.
[0049] According to the practice at the construction site, there are more than 10,200 welds in total for the instrument pipes. The modular instrument support device of the present utility model can prefabricate 4,500 welds in advance, accounting for 44% of the total. Among them, it takes about 10 minutes for one weld (including cutting, grinding, and welding). During the peak period, 750 hours can be saved, greatly improving the construction efficiency.
[0050] Although the present utility model is disclosed above with preferred embodiments, it is not intended to limit the present utility model.
