Description of drawings
Fig. 1 is the structural representation of oil-base mud measuring pad in the embodiment of the invention;
Fig. 2 is that Fig. 1 is along the sectional view of A-A direction;
Fig. 3 is that Fig. 1 is along the right view of the sectional view of B-B direction.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, hereinafter in connection with accompanying drawing embodiments of the invention are elaborated.Need to prove, in the situation that do not conflict, the feature among the present embodiment and the embodiment is any combination mutually.
Among the embodiment disclosed by the invention, a kind of oil-base mud measuring pad is provided, as shown in Figure 1, comprise probe 2 and pole plate 1, the oil-base mud measuring pad also comprise be separately positioned on described probe 2 both sides and be fixedly connected with described probe 2 two probe securing cover plates 3,4, two probe securing cover plates 3,4 and pole plate 1 between be bolted to connection.
The problem of processing and safeguarding for being not easy to of causing of pole plate in the prior art and probe one processing, the embodiment of the invention will pop one's head in 2 and separately design processing of pole plate 1, then carry out detachable connection, when wherein a part is damaged, the part of damaging can be disassembled and safeguard.
Further improvement as above-mentioned embodiment, as depicted in figs. 1 and 2, pole plate 1 comprises Polar plate matrix 12, pole plate lid 5 and pole plate bottom 6, and laser seal welding is adopted in the junction of Polar plate matrix 12 and pole plate bottom 6, is detachable the connection between pole plate lid 5 and the Polar plate matrix 12.
Laser seal welding is to utilize high-octane laser pulse material to be carried out the spot heating of tiny area, and the energy of laser emission will form specific molten bath to reach the purpose of welded seal after the material fusing by the diffusion inside of heat conduction to material.Laser weld has that weld width is little, the heat-affected zone is little, distortion is little, speed of welding is fast, smooth welded seam is attractive in appearance, weldquality is high, pore-free.The pole plate of laser seal welding can bear the impact of high temperature (200 ℃) high pressure (140MPa) and be indeformable, non-leakage.Laser weld becomes simply the design of pole plate 1 and processing, greatly reduces cost, has improved the reliability of pole plate integral body.
Can be detachable connection the such as hinged between pole plate lid 5 and the Polar plate matrix 12, be convenient to that pole plate is covered circuit board under 5 and safeguard and change.
As the further improvement to above-mentioned embodiment, pole plate 1 also comprises sealing plug 7, between an end of sealing plug 7 and the Polar plate matrix 12 for being threaded.Being threaded between sealing plug 7 and the Polar plate matrix 12 is convenient to quick grafting, replacing and the maintenance between sealing plug 7 and the pole plate 1.
As the further improvement to above-mentioned embodiment, as shown in Figure 3, pole plate 1 also comprises at least one crossed beam trunking (Fig. 3 shows two crossed beam trunkings 10,11), and the wire crossed beam trunking 10 of the end that sealing plug 7 is connected with pole plate 1,11 is connected with the circuit board of pole plate 1 inner chamber under the pole plate lid 5.Take 7 core sealing plugs as example, 7 wires of the left end of 7 core sealing plugs 7 welding are divided into two strands, and one 3 wires are on the circuit board below crossed beam trunking 10 arrival pole plate lids 3; One 4 wires are on the circuit board below crossed beam trunking 11 arrival pole plate lids 3.The left end of 7 core sealing plugs 7 is connected with the pole plate body and is connected, and right-hand member can be connected with SUB and be connected, and plate-line adopts integrated and modularized design like this, and thread-changing is easy.
