The specific embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the present invention, and can not be interpreted as limitation of the present invention.
Describe in detail according to the drilling equipment of ground under water 1 of the present invention below with reference to Fig. 1-Fig. 4, wherein Fig. 1 has shown the structural representation of the counter-force bracing or strutting arrangement of the drilling equipment of ground under water according to an embodiment of the invention.
As Fig. 1-shown in Figure 4, ground drilling equipment 1 comprises that counter-force bracing or strutting arrangement 11, vacuum form device 12, drilling apparatus 13, control device (not shown) and creep into DATA REASONING and the treating apparatus (not shown) under water.
Counter-force bracing or strutting arrangement 11 is used under water, and ground drilling equipment 1 provides counter-force.Counter-force bracing or strutting arrangement 11 comprises: drilling rod is placed and is connected and propelling module 112, vacuum drilling cabin 113 and injection cabin 114 with control cabinet 111, drilling rod.Alternatively, drilling rod is placed and to be connected with control cabinet 111, drilling rod and propelling module 112 and injection cabin 114 are the round barrel shape cabin that cross section is a circle, and vacuum drilling cabin 113 can be the awl tubular cabin of upper end diameter less than lower end diameter.
Wherein, drilling rod placement and control cabinet 111 are used to hold drilling rod 131 and control device.Drilling rod connects with propelling module 112 and is connected with accommodation chamber with the drilling rod placement, is used to hold drilling apparatus 13.Vacuum drilling cabin 113 is connected with drilling rod with propelling module 112 and is connected.Injection cabin 114 is connected with vacuum drilling cabin 113, is used for injection in ground under water.In an example of the present invention, counter-force bracing or strutting arrangement 11 also comprises water and soil separator 16.Alternatively, water and soil separator 16 can be separating plate, this separating plate 16 is arranged between vacuum drilling cabin 113 and the injection cabin 114, and on separating plate 16, be formed with a lot of holes, be used for the water in injection cabin 114 is realized the isolation of water and mud, can prevent that the mud in the ground under water from entering in the vacuum drilling cabin 113.
In the drilling equipment of ground under water 1 of the present invention, counter-force bracing or strutting arrangement 11 adopts the principle of suction barrel base, promptly by the vacuum pump that is placed on the bucket top system is vacuumized, and promptly can form initiatively suction to seabed mud face, as shown in Figure 2.Under the effect of this suction, the counter-force bracing or strutting arrangement 11 injection seabed mud face certain depths of barrel shape form a sealing system.Because the inside and outside huge pressure differential of bucket, make the suction of 11 pairs of seabeds of counter-force bracing or strutting arrangement mud face constitute the major part of creeping into needed counter-force, the weight that also has ground drilling equipment under water 1 itself in addition, also add the size of described counter-force extraly, and increased the stability of underwater exploration further.According to calculating, for example, be 2m and the high counter-force that about 15-50 ton can be provided for the counter-force bracing or strutting arrangement 11 of 3.0-4.0m of bucket according to bucket of the present invention footpath.
Because ground drilling equipment 1 need be worked under the environment of sealing under water, therefore, in an example of the present invention, ground drilling equipment 1 also comprises the sealing device 15 that counter-force bracing or strutting arrangement 11 is sealed under water, under the high pressure of deep-sea counter-force bracing or strutting arrangement 11 is sealed.
