Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a pickup for a pipe detector. Background Technique

[0002] PE pipes can be used as water conveyance pipes and gas transmission pipes, etc. It is a thermoplastic resin with high crystallinity and non-polarity, and has good corrosion resistance. It can be used as an underground embedded pipe; during construction, since workers cannot understand the embedded depth of the PE pipe, the pipe may be dug off, and the resulting losses are immeasurable. Therefore, before construction, the staff needs to detect the embedded depth of the PE pipe.

[0003] Due to the characteristics of non-magnetic and non-conductive of PE pipes, a special PE pipe detector is required for pipeline detection, and it mainly uses sound waves for pipeline position detection. For example, the new pipeline detector with the publication number CN206429806U emits sound waves to the pipeline through a transmitter, and then collects the sound wave signals on the ground through a pickup, and then determines the pipeline position. However, the pickup used is usually placed on the ground for use. During the detection process, the pickup needs to be frequently picked up and placed, which will inevitably cause the pickup to fall and collide. Such an impact will have an adverse effect on the performance and mechanical structure of the pickup. Content of the Utility Model

[0032] 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. 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.

[0033] As Figures 1-4 shown, the pickup of the logging sonde of the present utility model includes a metal cylinder 1, a fixing member 2, a sound wave receiving member 3, a support 4 and a flexible protection member 8.

[0034] The metal cylinder 1 is integrally arranged in a cylindrical shape with openings at both sides, and its interior is hollow. Preferably, it is made of aluminum alloy, which has good mechanical stability and the advantage of being lightweight. The length is preferably more than ten centimeters to facilitate the user's holding operation.

[0035] In addition, in order to facilitate the installation of other components on the metal cylinder 1 and reduce the fixed installation procedure of the components, one end of the metal cylinder 1 is provided with an outward expansion structure. By changing the main diameter of the metal cylinder 1, the components sleeved on the metal cylinder 1 can be blocked and fixed.

[0036] The fixing member 2 is arranged in one opening of the metal cylinder 1 and is fixed to the metal cylinder 1. The interior of the fixing member 2 is hollow and is made of the same material as the metal cylinder 1. One end of the fixing member 2 extends into the metal cylinder 1 and is fixed to the metal cylinder 1 by threads. The outer diameter of the other end of the fixing member 2 is larger than the inner diameter of the metal cylinder 1 and fits with the outward expansion structure on the metal cylinder 1 to form a fastening structure in cooperation with the threads.

[0037] The sound wave receiving member 3 is fixed in the metal cylinder 1. The sound wave receiving member 3 includes a receiving end 31. The receiving end 31 penetrates through the fixing member 2 and extends to the outside of the metal cylinder 1, and cooperates with the fixing member 2 to seal the opening on this side of the metal cylinder 1.

[0038] Specifically, the sound wave receiving member 3 is preferably a piezoelectric sensor. In the metal cylinder 1, a sensor installation section is also provided. The inner diameter of the sensor installation section is larger than that of the rest of the part, so that when the sound wave receiving member 3 is installed in the metal cylinder 1, the stepped structure formed by the different inner diameters supports one end of the sound wave receiving member 3, and the other end of the sound wave receiving member 3 extends to the outside of the metal cylinder 1 through the inside of the fixing member 2 to form the receiving end 31. The part of the sound wave receiving member 3 located inside the fixing member 2 is fixedly connected to the fixing member 2.

[0039] The support 4 is fixed on the receiving end 31. The support 4 includes at least three feet 41 which are used to insert into the soil to make the metal cylinder 1 stand upright on the ground, so that the detected sound waves are transmitted to the receiving end 31 through the ground and the feet 41.

[0040] In this embodiment, the number of feet 41 of the support 4 is set to three, and they are arranged around the receiving end 31 at an angle of sixty degrees. At the bottom end of the feet 41, a semi-circular structure that can be inserted into the soil is provided to increase the receiving sensitivity of the sound waves transmitted by the ground by inserting into the soil.

[0041] The flexible protection member 8 is coated on the outside of the metal cylinder 1 and extends to the outside of the support 4. The flexible protection member 8 is preferably made of silica gel. Its extension to the outside of the support 4 can provide good protection for the overall structure of the pickup. At the same time, after the flexible protection member 8 is coated on the outside of the metal cylinder 1, there will be greater friction when the user holds it, further reducing the risk of the pickup slipping out of the hand.

[0042] During the assembly process of the pickup, first insert the sound wave receiving member 3 into the metal cylinder 1, and twist the fixing member 2 to fix it to the metal cylinder 1. Then install the support 4 on the receiving end 31. It should be noted that during the processing and production process, the flexible protection member 8 needs to be first sleeved on the outside of the metal cylinder 1.

[0043] In this embodiment, it further includes an end cap assembly 5. The end cap assembly 5 is fixed on one end of the metal cylinder 1 away from the support 4 and seals the opening at this end of the metal cylinder 1, so as to form a closed chamber inside the metal cylinder 1.

[0044] Specifically, the end cap assembly 5 includes a metal base 51, a plastic cover 52 and a power circuit board 53. The metal base 51 is fixed at the end of the metal cylinder 1 to block the opening of the metal cylinder 1. The plastic cover 52 is fixed on the side of the metal base 51 away from the metal cylinder 1 and forms a sealed cavity with the metal base 51. The power circuit board 53 is fixed inside the plastic cover 52 and is located in the sealed cavity.

[0045] The metal base 51 is made of aluminum alloy. A circular protrusion is provided at the bottom of the metal base 51, and this circular protrusion is sleeved on the end of the metal cylinder 1. A sealing ring is also provided between the metal cylinder 1 and the circular protrusion. Since the power circuit board 53 needs to install a charging port, the plastic cover 52 is provided to install the power circuit board 53. A plurality of power indicator lights electrically connected to the power circuit board 53 are also provided on the plastic cover 52 to display the battery level.

[0046] Correspondingly, a storage battery 6 is also provided. The storage battery 6 is arranged inside the metal cylinder 1, and the inner diameter of the metal cylinder 1 is adapted to the storage battery 6. The storage battery 6 is a cylindrical battery and is connected to a charging wire through a power circuit board 53 to perform a charging operation on the storage battery 6.

[0047] As a preferred embodiment, a pull ring is further installed on the end cover assembly 5. The pull ring can be tied with a rope. After the detection at a certain position is completed, the operator can directly pick up the pickup by pulling the rope, reducing the bending frequency and thus improving the operation efficiency. Considering the limited bearing capacity of the plastic cover 52, the pull ring is directly fixed to the metal base 51 through a screw and a metal post to ensure the structural stability.

[0048] In this embodiment, a lower housing assembly 7 is also provided. The lower housing assembly 7 is fixed to one end of the metal cylinder 1 close to the support 4 and is arranged around the outside of the metal cylinder 1. The flexible protection member 8 is wrapped around the outside of the metal cylinder 1 and the lower housing assembly 7.

[0049] Specifically, the lower housing assembly 7 includes a first housing 71, a second housing 72 and a communication circuit board 73. The first housing 71 is sleeved outside the metal cylinder 1 and is fixed to the metal cylinder 1. The second housing 72 is arranged outside the metal cylinder 1 and is buckled on one side of the first housing 71 close to the support 4. The communication circuit board 73 is fixed inside the second housing 72. The communication circuit board 73 is electrically connected to the sound wave receiving member 3 and is used for transmitting the received signal outward.

[0050] Considering that if the pickup and the exploration instrument transmit signals through a wire, it will cause the exploration instrument and the pickup to need to move together, which is not conducive to continuous detection operations at multiple positions. In this embodiment, a communication circuit board 73 is provided so that it can transmit signals through Bluetooth or WiFi, etc., to achieve wireless connection, and then transmit the detected signals.

[0051] The first housing 71 and the second housing 72 are both made of plastic. The antenna of the communication circuit board 73 can be directly pasted on the inner side wall of the second housing 72. Correspondingly, the provided flexible protection member 8 is wrapped around the outside of the first housing 71 and the second housing 72 to protect them.

[0052] During the assembly process, first install the communication circuit board 73 in the second housing 72, then fix the first housing 71 and the second housing 72 together and sleeved them outside the metal cylinder 1 until the second housing 72 abuts against the outward expansion structure of the metal cylinder 1, and fix them with bolts. Then install the flexible protection member 8, and finally install the end cover assembly 5 to fix the flexible protection member 8.

[0053] As a preferred embodiment, the flexible protection member 8 includes a straight tube portion 81, a transition portion 82 and an umbrella-shaped portion 83. The straight tube portion 81, the transition portion 82 and the umbrella-shaped portion 83 are integrally formed. The straight tube portion 81 is sleeved outside the metal cylinder 1, the umbrella-shaped portion 83 covers the lower housing assembly 7, and the transition portion 82 is arranged between the straight tube portion 81 and the umbrella-shaped portion 83 to connect the outer surfaces of the straight tube portion 81 and the umbrella-shaped portion 83 through an arc surface.

[0054] The straight tube portion 81 corresponds to the metal cylinder 1. During use, the user can directly hold the straight tube portion 81, while the umbrella-shaped portion 83 covers the lower housing assembly 7 to protect the lower housing assembly 7 and further improve the waterproof effect between the lower housing assembly 7 and the metal cylinder 1. The provided transition portion 82 enables a smooth transition between the straight tube portion 81 and the umbrella-shaped portion 83, improving the holding feel.

[0055] In addition, anti-slip patterns are provided on the straight tube portion 81 to further increase the friction during the user's holding process.

[0056] As a preferred embodiment, the support 4 further includes a connecting member 42. The connecting member 42 is threadedly connected to the receiving end 31, and the support feet 41 are all fixed on the connecting member 42. This arrangement allows the support 4 to be disassembled when storing the pickup, preventing the support 4 from being accidentally impacted and affecting the sound wave receiving member 3. Also, the receiving end 31 of the removed support 4 can be protected by the skirt extended from the umbrella-shaped portion 83.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
