Description

Technical Field

[0001] The utility model relates to the technical field of probe bins, in particular to a novel probe bin structure with large displacement. Background Art

[0002] In horizontal directional drilling applications, the probe chamber structure plays a key role in the stable operation and precise measurement of the entire system. With the widespread application of horizontal directional drilling technology in complex geological environments and long-distance pipeline laying projects, the working conditions of screw motor mud pumps have become increasingly harsh. The probe chamber needs to accurately monitor various parameters of the screw motor mud pump, such as pressure, temperature, and speed, in an environment with high pressure, high humidity, and the possible presence of impurities such as mud and sand, providing reliable data support for the smooth progress of the project. However, the traditional probe chamber structure has gradually revealed its limitations in responding to these challenges and is unable to meet the growing engineering needs. This has made the development of a new large-displacement probe chamber structure an urgent need in the industry.

[0003] Existing probe silos generally consist of a simple silo body and basic sealing components. The mechanical structure is often composed of a standard metal silo body, sealed with a single-layer rubber seal at the junction of the silo cover and the silo body, secured with bolts. Technically, this system relies primarily on the elastic deformation of the seal to fill gaps and prevent water ingress. Probes are often simply placed within the silo, lacking precise positioning and a stable support structure. Signal transmission relies on relatively basic wiring connections, resulting in limited transmission stability and anti-interference capabilities. Drainage typically relies on small slurry pumps, resulting in a simple drainage piping layout and lack of optimized design for large displacements and complex operating conditions.

[0004] A serious problem with existing technologies is the low actual drainage capacity, which poses a high risk of damage to the mud pump. The drainage system design of traditional probe chambers is relatively rudimentary, with limited mud pump power, small drainage pipes, and an illogical layout. These drainage limitations are further magnified in the backpressure environment of horizontal directional drilling (HDD) screw motor mud pumps. When encountering large water volumes, the drainage rate far outstrips the inflow rate, leading to a rapid accumulation of water within the chamber. Mud pumps operating at full or even overloaded conditions for extended periods are prone to failure due to overheating and overloading. Frequent starts and stops, coupled with high-pressure operation, can increase wear on key components such as the mud pump's plunger and seals, significantly shortening their service life. Furthermore, the large drainage pumps used for drainage suffer from insufficient flow from the carbon rod chamber, leading to irregular internal drainage and prolonged high pressure conditions. This further impacts the performance and reliability of the mud pump, increases equipment maintenance costs and downtime, and severely restricts the efficient and stable implementation of HDD projects. Therefore, a new, high-displacement probe chamber structure is proposed to address these issues. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1 - Figure 3The utility model provides an embodiment: a novel large-displacement probe chamber structure, including a probe chamber 1, the probe chamber 1 as the main body of the entire device, used to withstand external pressure and accommodate other structural parts, a sealing component, the sealing component is arranged inside the probe chamber 1, used to seal the entirety to prevent water from entering, a detection component, the detection component is arranged at both ends of the probe chamber 1, used to detect and drain the bottom, a signal transmission 3, the signal transmission 3 is arranged inside the probe chamber 1, used to transmit bottom information to the ground, a sealing component, the sealing component includes a sealing plug 2 and a sealing plug 25, the outer wall of the sealed plug 2 is slidably connected to the inside of the probe bin 1, the outer wall of the sealed plug 25 is slidably connected to the inside of the probe bin 1, the material of the sealed plug 2 is a round steel hollowing process, the material of the sealed plug 25 is a round steel hollowing process, the detection component includes two end heads 4, the outer walls of the two end heads 4 are arranged at both ends of the probe bin 1, the outer walls of the end heads 4 are provided with drill rod threads 6, the bottom of the end heads 4 are fixedly connected with a connecting column 7, the connecting column 7 is arranged inside the probe bin 1, the other end of the connecting column 7 is fixedly connected to the outer wall of the other end head 4, a drainage groove 8 is opened inside the end head 4, and a probe window 9 is opened inside the end head 4.

[0029] Specifically, during detection operations, the probe chamber 1 plays a crucial role. When probe chamber 1 is used for detection, sealing plugs 1 and 2 work closely together to seal the entire device. Their excellent sealing properties effectively prevent water from entering the chamber from the top. Even during long-term operations or in extremely harsh underwater environments, the chamber remains dry, creating excellent conditions for the stable operation of the internal equipment. Furthermore, signal transmission 3 technology accurately and efficiently transmits detection information to the ground control center, enabling personnel to conduct timely data analysis and make decisions. Before the detection work is carried out, the end 4 is firmly installed in the probe chamber 1 by using the drill pipe thread 6, which greatly enhances the stability of the probe window 9 inside the device and effectively avoids measurement errors or equipment failures caused by loose components during the detection process. The drainage space is increased during use, which increases the drainage volume and avoids damage caused by back pressure of the mud pump. At the same time, both the inside and the outside are made of pure steel, which can greatly improve the service life. During the actual use of the device, the drainage groove 8 begins to play its key role and quickly discharges the internal accumulated water. At the same time, it is processed by electric welding before drilling to improve the main effect. The larger probe window 9 can work in conjunction with the mud pump to more smoothly drain the mud. The water source in the bin is extracted and discharged, which effectively avoids the situation that the actual displacement and the mud pump pressure cannot be adapted due to the tight internal space when the probe is placed in the probe window 9 which is too small, and prevents the mud pump from being damaged due to this mismatch, effectively guarantees the stable operation of the entire drainage system and the normal working efficiency of the probe bin 1, and significantly improves the reliability and durability of underwater detection operations. At the same time, the inner wall of the traditional probe bin 1 uses nylon material as an internal and external water barrier. Under long-term high-pressure back pressure environment, the nylon rod is very easy to cause chamber damage, etc., while the utility model uses the drainage groove and the probe window 9 to prevent the internal chamber from being damaged in a high-pressure environment, thereby greatly improving the screw speed and working efficiency of the mud pump.

[0030] Working principle: When using the probe chamber 1 for detection, the device is sealed by sealing plug 1 2 and sealing plug 2 5 to effectively prevent water from seeping into the chamber from the top. Even in long-term operations or harsh environments, the dryness of the chamber can be guaranteed, and the detection information is transmitted to the ground through signal conduction 3. At the same time, before detection, the end 4 is fixed inside the probe chamber 1 through the drill pipe thread 6 to keep the device stable. When the device is in use, the internal water is discharged through the drainage groove 8. At the same time, the larger probe window 9 is used to better cooperate with the mud pump to extract and discharge the water source, to prevent the probe window 9 from being too small, which may easily lead to a mismatch between the actual displacement and the mud pump pressure and cause damage to the mud pump.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
