Description

Technical Field

[0001] This utility model belongs to the field of outdoor pipeline inspection technology, and in particular relates to a handheld leak detector for outdoor pipeline inspection. Background Technology

[0002] In outdoor pipeline inspection work, handheld leak detectors play a crucial role. They can accurately capture the sound signals generated by pipeline leaks, helping staff to quickly locate the leak point. This is of great significance for ensuring the normal operation of the pipeline network, reducing resource waste, and avoiding potential safety hazards.

[0003] However, some existing handheld leak detectors often lack effective protective structures. In complex outdoor environments, the detectors are often subjected to collisions, friction, and rain erosion. Due to insufficient protection, the instrument shell is prone to scratches and damage, which not only affects its appearance but may also cause internal components to loosen or become damaged. Utility Model Content

[0004] The purpose of this invention is to provide a handheld leak detector for outdoor pipeline inspection. By incorporating a protective mechanism, specifically placing the detector body within a protective pad on the inner wall of the outer casing, the pad buffers external impacts and prevents equipment damage. When protection is needed, the cover plate rotates on the fixing plate via a pin of the flipping component, causing the connecting plate to flip and close the outer casing. The magnet of the fixing component adheres to the metal block, securing the cover plate. During use, external force overcomes the adhesion to open the cover plate. Pre-drilled holes in the outer casing and protective pad ensure normal connection of the detection probe and earphone cable. This effectively protects the equipment without affecting its use, meeting the portability and protection requirements of outdoor inspections and solving the problem that some existing handheld leak detectors typically lack effective protective structures.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a handheld leak detector for outdoor pipeline inspection, comprising a housing, inside which the leak detector body is installed, and further comprising: a protective mechanism disposed on the housing, the protective mechanism being used to protect the leak detector body, the protective mechanism including a cover plate installed on the front side of the housing, and a protective pad installed on the inner wall of the housing; and a sealing mechanism disposed on the housing, the sealing mechanism being used to seal the gap between the cover plate and the housing when the cover plate closes the housing, the sealing mechanism including a sealing groove opened on the front side of the housing, and pre-drilled holes on both the housing and the protective pad for connecting the detection probe and the earphone connection cable to the leak detector body.

[0007] Furthermore, the protective mechanism also includes a flipping component disposed at the bottom of the housing, which is used to enable the cover to flip; and a fixing component disposed on the housing and the cover, which is used to fix the position of the cover when the cover closes the housing.

[0008] Furthermore, the flipping assembly includes a fixed plate fixedly connected to the bottom of the outer shell, a pin passing through the fixed plate, the pin being rotatably connected to the fixed plate, and connecting plates fixedly connected to both ends of the pin. The side of each connecting plate away from the pin is fixedly connected to the bottom of the cover plate. Both connecting plates are designed in an L-shape, and both connecting plates are fixedly connected to the pin and the cover plate by welding.

[0009] Furthermore, the fixing component includes a mounting groove formed on the front side of the housing, a magnet is installed on the inner wall of the mounting groove, a metal block passes through the cover plate, the metal block is fixedly connected to the cover plate, the metal block is designed to be rectangular, and the size and shape of the metal block are the same as those of the magnet, and the metal block is fixedly connected to the cover plate by welding.

[0010] Furthermore, the sealing mechanism also includes a sealing ring fixedly connected to the inner wall of the sealing groove, the sealing ring being made of integrally molded rubber.

[0011] Furthermore, a groove is provided on the side of the sealing ring near the cover plate, and a protrusion is fixedly connected to the side of the cover plate near the sealing ring. The side of the protrusion away from the cover plate extends into the interior of the groove and is slidably connected to the groove.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model incorporates a protective mechanism, specifically placing the main body of the sound leakage detector within a protective pad on the inner wall of the outer casing. The protective pad buffers external impacts, preventing damage to the equipment. When protection is required, the cover plate rotates on the fixing plate via the pin of the flipping component, causing the connecting plate to flip and close the outer casing. The magnet of the fixing component adheres to the metal block, securing the cover plate. During use, external force can overcome the adsorption force to flip and open the cover plate. The pre-drilled holes in the outer casing and the protective pad ensure normal connection of the detection probe and earphone cable, effectively protecting the equipment without affecting its use, thus meeting the portability and protection needs of outdoor inspections.

[0014] 2. This utility model features a sealing mechanism. Specifically, when the cover plate closes the outer shell, the protrusion on the cover plate smoothly penetrates into the conical groove of the sealing ring. The rubber sealing ring is compressed and deformed evenly, tightly fitting the protrusion and the inner wall of the sealing groove, completely filling the connection gap between the cover plate and the outer shell. The arc transition and tapered design of the groove ensure that the protrusion opens and closes without jamming, effectively preventing outdoor dust, rainwater, mud and other impurities from entering the interior of the outer shell, avoiding contamination or short circuit damage to the main body of the leakage detector, and ensuring stable operation of the equipment in complex outdoor environments.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 As shown, this utility model is a handheld leak detector for outdoor pipeline inspection, including a housing 1, with the detector body 11 installed inside the housing 1, and further including: a protective mechanism 2, which is disposed on the housing 1 and is used to protect the detector body 11. The protective mechanism 2 includes a cover plate 21 installed on the front side of the housing 1, and a protective pad 211 installed on the inner wall of the housing 1; a sealing mechanism 3, which is disposed on the housing 1 and is used to seal the gap between the cover plate 21 and the housing 1 when the housing 1 is closed. The sealing mechanism 3 includes a sealing groove 31 opened on the front side of the housing 1; the protective mechanism 2 also includes a flipping component 22, which is disposed at the bottom of the housing 1 and is used to enable the cover plate 21 to flip; and a fixing component 23, which is disposed on the housing 1 and the cover plate 21 and is used to fix the position of the cover plate 21 when the housing 1 is closed.

[0027] The flipping assembly 22 includes a fixing plate 221 fixedly connected to the bottom of the outer casing 1. A pin 222 passes through the fixing plate 221 and is rotatably connected to the fixing plate 221. Connecting plates 223 are fixedly connected to both ends of the pin 222. The sides of the two connecting plates 223 away from the pin 222 are fixedly connected to the bottom of the cover plate 21. The fixing assembly 23 includes a mounting groove 231 opened on the front side of the outer casing 1. A magnet 232 is installed on the inner wall of the mounting groove 231. A metal block 233 passes through the cover plate 21 and is fixedly connected to the cover plate 21. A protective mechanism 2 is set, specifically for leak detection. The instrument body 11 is placed inside the protective pad 211 on the inner wall of the outer shell 1. The protective pad 211 can buffer external impacts and prevent damage to the equipment. When protection is required, the cover plate 21 rotates on the fixing plate 221 by means of the pin 222 of the flipping component 22. The connecting plate 223 drives it to flip and close the outer shell 1. The magnet 232 of the fixing component 23 and the metal block 233 attract and fix the cover plate 21. When in use, the cover plate 21 can be flipped open by external force overcoming the attraction force. The reserved holes of the outer shell 1 and the protective pad 211 ensure normal connection of the detection probe and the earphone connection cable. It effectively protects the equipment without affecting its use and meets the portability and protection needs of outdoor inspection.

[0028] The sealing mechanism 3 also includes a sealing ring 311 fixedly connected to the inner wall of the sealing groove 31. The sealing ring 311 is made of rubber in one piece. A groove 312 is provided on the side of the sealing ring 311 near the cover plate 21. A protrusion 313 is fixedly connected on the side of the cover plate 21 near the sealing ring 311. The side of the protrusion 313 away from the cover plate 21 extends into the interior of the groove 312 and slides in connection with the groove 312. When the cover plate 21 is closed, the protrusion 313 gradually penetrates into the conical inner wall of the groove 312 and squeezes the sealing ring 311, so that the sealing ring 311 undergoes uniform deformation and fits tightly with the protrusion 313 and the sealing groove 31. By setting a sealing mechanism 3, specifically when the cover plate 21 closes the outer shell 1, the protrusion 313 on the cover plate 21 smoothly enters along the conical groove 312 of the sealing ring 311. The rubber sealing ring 311 is squeezed and deformed evenly, tightly fitting the protrusion 313 and the inner wall of the sealing groove 31, completely filling the connection gap between the cover plate 21 and the outer shell 1. The arc transition and tapered design of the groove 312 ensure that the protrusion 313 is not stuck when opening and closing, effectively preventing outdoor dust, rainwater, mud and other impurities from entering the interior of the outer shell 1, avoiding contamination or short circuit damage to the main body 11 of the leak detector, and ensuring stable operation of the equipment in complex outdoor environments.

[0029] A specific application of this embodiment is as follows: When it is necessary to protect the body 11 of the sound leakage detector, the cover plate 21 is flipped by the flipping component 22. The pin 222 rotates on the fixing plate 221, driving the connecting plate 223 and the cover plate 21 to rotate to the position of the closed outer shell 1. At this time, the fixing component 23 plays a role, and the magnet 232 in the mounting groove 231 attracts the metal block 233 on the cover plate 21, fixing the position of the cover plate 21 and making the outer shell 1 in a closed state; the protective pad 211 on the inner wall of the outer shell 1 covers the body 11 of the sound leakage detector, and can When the device is subjected to external impact or collision, it acts as a buffer, reducing the damage to the main body 11 of the leak detector. At the same time, the reserved holes on the outer shell 1 and the protective pad 211 ensure that the connection wires of the detection probe and the earphone can be connected normally to the main body 11 of the leak detector without affecting the normal detection function of the device. When the main body 11 of the leak detector needs to be used, external force is applied to make the cover plate 21 overcome the attraction between the magnet 232 and the metal block 233. The cover plate 21 is flipped open by the flipping component 22, and the main body 11 of the leak detector can be operated to carry out pipeline inspection work.

[0030] During the process of the cover plate 21 being flipped into the closed housing 1 by the flipping component 22, the protrusion 313 on the cover plate 21 gradually approaches and enters the groove 312 on the sealing ring 311. Since the cross-sections of the groove 312 and the protrusion 313 are both matching isosceles cones, the protrusion 313 can slide smoothly along the conical inner wall of the groove 312 and gradually penetrate deeper. As the cover plate 21 continues to close, the protrusion 313 exerts a squeezing effect on the inner wall of the groove 312, causing the sealing ring 311, which is made of rubber in one piece, to undergo uniform deformation. This deformation allows the sealing ring 311 to not only fit tightly against the outer peripheral wall of the protrusion 313, but also fit tightly against the inner wall of the sealing groove 31, thereby effectively filling the gap at the connection between the cover plate 21 and the housing 1, preventing external dust, moisture, mud and other impurities from entering the interior of the housing 1 through the gap, avoiding contamination or damage to the main body 11 of the leak detector, and ensuring that the equipment can work stably in complex environments such as outdoor pipeline inspection.
