Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of fishing aids, and particularly relates to an underwater fish collecting lamp. BACKGROUND

[0002] With the development of modern fishing technology, the underwater fish collecting lamp, as an important fishing aid, is widely used in marine fishing, deep water aquaculture and light trapping operations. It attracts phototactic fish through specific wavelength light sources, significantly improving the fishing efficiency. However, due to long-term work in harsh environments such as high humidity, high salt fog and even deep water high pressure, the underwater fish collecting lamp has very high requirements for waterproof sealing performance.

[0003] At present, the underwater lamps on the market mostly use O-shaped sealing rings combined with screw fastening structures to realize the sealing between the lamp body and the end cover. Some products also coat sealing glue at the joint to enhance the waterproof effect.

[0004] However, such traditional structures have many defects: on the one hand, it is difficult for the elastic sealing ring to resist water pressure penetration for a long time, especially in the working conditions of large depth or frequent temperature changes, which is prone to aging deformation, resulting in sealing failure; on the other hand, the sealing glue is mostly applied by hand, which is difficult to ensure uniform filling, bubble-free and no omission, and lacks effective guiding path, resulting in uneven distribution of the glue, forming local weak points, which seriously affects the waterproof reliability of the whole lamp. SUMMARY

[0005] The present application is directed to the above-mentioned problems existing in the prior art, and proposes an underwater fish collecting lamp with improved sealing performance.

[0014] As a further improvement of the present application, the glue outlet hole is arranged on the top surface of the second protruding part, and the sealant flows along the top surface of the second protruding part into the first sealing groove and the second sealing groove.

[0015] As a further improvement of the present application, a distance is left between the lamp cylinder light source module and the lamp cylinder lampshade to form an air flow passage for heat dissipation and sealing detection, and the upper mounting plate and the lower mounting plate are respectively provided with a first air hole and a second air hole on the end surface away from the lamp cylinder assembly, and the first air hole and the second air hole are respectively communicated with the air flow passage.

[0016] As a further improvement of the present application, the first air hole and the second air hole are configured as:

[0017] When one of them is closed, the other air hole can be used to inject gas to check the sealing;

[0018] When both of them are open, gas can be injected through them to discharge and replace the air in the air flow passage.

[0019] As a further improvement of the present application, the upper mounting plate is further provided with a wire containing groove on the end surface away from the lamp cylinder assembly, and the wire containing groove is used to contain the wire and is sealed by the sealant.

[0020] As a further improvement of the present application, the upper mounting plate is provided with a hanging rope mounting seat on the end surface away from the lamp cylinder assembly, and the lower mounting plate is provided with a bottom base on the end surface away from the lamp cylinder assembly.

[0021] As a further improvement of the present application, the bottom base has a containing cavity therein and is used to mount a bottom light source, wherein,

[0022] The containing cavity includes an inner mounting groove and an outer mounting groove, and the outer mounting groove is communicated with the inner mounting groove and is transitioned through a stepped surface.

[0023] The bottom light source comprises a bottom light source module and a bottom light source protective glass, the bottom light source module is arranged in the inner mounting groove, and the bottom light source protective glass is mounted on the outer mounting groove.

[0024] As a further improvement of the application, the bottom base is provided with an inner recessed clamping groove on the inner side wall of the outer mounting groove, when the bottom light source protective glass is mounted on the outer mounting groove, a distance is left between the side wall of the bottom light source protective glass and the inner side wall of the bottom base to form a glue injection space, and the clamping groove and the glue injection space are connected to form a common glue injection area.

[0025] As a further improvement of the application, a power distribution box is further provided, two ends of the power distribution box are connected with the hanging rope mounting seat and an external power source through a first cable and a second cable respectively, and the first cable, the second cable and the power distribution box are detachably connected.

[0026] Compared with the prior art, the application has the following beneficial effects:

[0027] 1. Double-sided double-layer composite sealing is realized, and the waterproof reliability is greatly improved: through synchronous glue injection sealing of the first mounting groove and the second mounting groove, combined with the flow guide structure of "glue injection hole-internal channel-glue outlet hole", a front and rear double-sided sealing barrier is formed, the external water environment is effectively isolated, water is prevented from entering the light source cavity from any direction, and the long-term waterproof performance of the lamp in a deep water high pressure environment is significantly improved.

[0028] 2. The glue injection process is controllable and uniform, and the process is highly repeatable: the sealant is injected from the glue injection hole, discharged from the glue outlet hole through the internal channel and naturally leveled, realizing the orderly filling of "one in and one out", avoiding bubble residue and uneven filling; the glue outlet hole is arranged on the top surface of the second protruding part, further optimizing the glue diffusion path, ensuring full, continuous and dead angle free filling of the sealing area, and improving production consistency and automation potential.

[0029] 3. Elastic sealing and rigid glue sealing are coordinated to build a multi-protection system: a double-layer sealing ring with a sealing groove is arranged in the mounting groove to form a "pre-sealing + main glue injection" composite sealing structure, which not only prevents glue leakage during glue injection, but also avoids stress damage caused by rigid contact through elastic buffering, significantly enhancing the sealing durability and vibration resistance.

[0030] 4. Airflow channel and double air hole design realize "detectable, dischargeable and preventable" intelligent sealing management: the airflow channel connects the double air holes, allowing bubble method sealing detection in water, and directly judging the leakage point; helium can also be injected to replace the internal air, which can improve the heat dissipation efficiency by using the excellent thermal conductivity of helium, prevent condensation and oxidation corrosion, and improve the environmental adaptability and service life of the lamp.

[0031] 5. Modular power supply, balancing economy and functionality: The distribution box connects to the detachable first and second cables, allowing users to reuse existing long cables, reducing purchase costs, and facilitating the replacement of vulnerable cables, thus improving maintenance convenience.

[0032] 6. Achieve multi-angle three-dimensional lighting and significantly improve fish attraction efficiency: By integrating an independent bottom light source into the base, the fish attraction lamp not only has circumferential light emission from the lamp tube assembly, but also achieves downward directional supplementary lighting, forming a composite light field distribution of "horizontal diffusion + vertical penetration". This design effectively expands the lighting coverage and light penetration depth of the water area below, and is especially suitable for attracting fish that swim towards light from the seabed or diagonally below (such as bottom fish, shrimp, etc.), breaking the blind spots of traditional fish attraction lamps and greatly improving the attraction effect and the targeting and efficiency of fishing operations.

[0033] 7. The bottom light source area achieves a three-level integrated seal: mechanical locking, adhesive anchoring, and surface encapsulation. By setting a snap-fit ​​groove on the inner side wall of the outer mounting groove, and forming a common injection area connected with the gap of the bottom light source protective glass side wall, the sealant is fully filled and cured. After injection, the sealant not only seals the gap between the lampshade and the base, but also forms a "glue nail" structure in the snap-fit ​​groove, producing a mechanical anchoring effect and enhancing pull-out resistance and vibration resistance. At the same time, the "pre-bonding + main injection" process prevents sealant leakage and extends the sealant to the root of the outer surface of the lampshade to form a continuous coating layer (outer edge sealing), constructing a complete sealing barrier. This design deeply integrates mechanical connection and adhesive sealing, achieving full-path sealing from internal anchoring to external protection, effectively preventing water intrusion, ensuring long-term stable operation of the bottom light source under high pressure and strong water flow, and significantly improving the overall waterproof rating, safety, and service life of the lamp.

[0046] The following is a specific embodiment of the present application and further describes the technical method of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0047] As Figures 1-6 shown, the present application provides an underwater fish collecting lamp, comprising:

[0048] The fish collecting lamp body comprises a lamp cylinder assembly 100, an upper mounting plate 200 and a lower mounting plate 210, the lamp cylinder assembly 100 comprises a lamp cylinder lampshade 100 and a lamp cylinder light source module 110 (the lamp cylinder light source module 110 comprises a mounting plate and a lamp plate arranged on the mounting plate) accommodated in the lamp cylinder lampshade 100, and the upper mounting plate 200 and the lower mounting plate 210 are respectively connected to the two end faces of the lamp cylinder assembly 100;

[0049] The end face structure of the upper mounting plate 200 and the lower mounting plate 210 for connecting with the lamp cylinder assembly 100 is the same, and comprises a first mounting groove and a second mounting groove arranged in the outer-to-inner interval, and the end of the lamp cylinder lampshade 100 is embedded in the first mounting groove, wherein,

[0050] A first protruding part 240 is formed on the outer periphery of the first mounting groove, and a glue injection hole 241 is arranged on the first protruding part 240;

[0051] A second protruding part 250 is formed between the first mounting groove and the second mounting groove, and a glue outlet hole 251 is arranged on the second protruding part 250;

[0052] The glue injection hole 241 is communicated with the glue outlet hole 251 through the internal passage of the upper mounting plate 200 or the lower mounting plate 210, and the glue outlet hole 251 is communicated with the first mounting groove and the second mounting groove. The sealant injected from the glue injection hole 241 is discharged from the glue outlet hole 251 through the internal passage, so as to simultaneously fill and seal the areas where the first mounting groove and the second mounting groove are located.

[0053] Specifically, the glue injection process is as follows:

[0054] After the assembly of the lamp cylinder lampshade 100 and the upper and lower mounting plates 210 is completed, the sealant is injected from the glue injection hole 241. The sealant first enters the passage in the first protruding part 240 and flows along the internal passage to the glue outlet hole 251. Since the glue outlet hole 251 is located in the second protruding part 250 and is communicated with the first mounting groove and the second mounting groove, the sealant is naturally diffused to the inside and the outside after being discharged from the glue outlet hole 251 under the action of pressure, gradually fills the areas of the first mounting groove and the second mounting groove, and naturally flows flat. After the sealant is naturally solidified after standing for a period of time, the entire sealing area is filled and sealed.

[0055] When the first mounting groove and the second mounting groove are sealed, the sealing between the lamp cylinder and the first mounting groove and the sealing between the mounting plate in the lamp cylinder assembly 100 and the second mounting groove are completed, thereby establishing reliable sealing interfaces on the front and back sides of the lamp panel (i.e., the area where the light source module is located) inside the lamp cylinder assembly 100. This front and back double-sided sealing structure completely isolates the internal cavity where the light source module is located from the external water environment, forms a double protection barrier, and effectively blocks the path of water intrusion from any direction into the core electronic components.

[0056] Compared with the prior art, this glue injection method has at least the following advantages:

[0057] 1. Double-sided and double-layer sealing protection: Through the synchronous glue injection sealing of the first mounting groove and the second mounting groove, a front and back double-sided sealing barrier for the area where the lamp cylinder light source module 110 is located is constructed, the external water environment is effectively isolated, and the waterproof reliability of the lamp under deep water high pressure conditions is significantly improved.

[0058] 2. Controllable and uniform filling during the glue injection process: The flow guide structure of the glue injection hole 241-internal passage-glue outlet hole 251 is adopted, a clear sealant flow path is formed, orderly filling from "one end in and one end out" is realized, problems such as uneven manual glue coating and bubble residue are avoided, and after the sealant naturally flows flat and solidifies, it can be ensured that the sealant fully, continuously and without dead angle fills the key sealing area.

[0059] 3. Improve the overall integrity and durability of the structure: after the sealant is cured, the lamp cylinder lamp shade 100, the mounting plate and the sealing groove structure are firmly combined, which enhances the mechanical strength and vibration resistance of the connection part, buffers the stress changes caused by thermal expansion and cold shrinkage, and prolongs the service life of the lamp in complex underwater environment.

[0060] Preferably, the first mounting groove and the second mounting groove are respectively provided with a first sealing ring 220 and a second sealing ring 230, and the first sealing ring 220 and the second sealing ring 230 are respectively provided with a first sealing groove and a second sealing groove. It is worth mentioning here that the setting of the first sealing ring 220 and the second sealing ring 230 forms an elastic compression seal between the lampshade and the mounting plate. The sealing ring is axially compressed during assembly, generating uniform springback force, ensuring that the lampshade and the sealing groove maintain continuous pre-tight contact, effectively preventing the seal from loosening due to vibration, temperature changes or mechanical impact. This structure forms a preliminary sealing barrier before glue injection, preventing the sealant from leaking to the non-target area inside during the glue injection process, and providing "double protection" for subsequent glue sealing.

[0061] That is, by setting a double-layer elastic sealing ring, not only is pre-sealing achieved before glue injection, but also a "elastic sealing + rigid glue sealing" composite sealing system is formed with the sealant after glue injection and curing, significantly improving the overall waterproof level and long-term stability.

[0062] At the same time, the elastic buffer effect of the sealing ring avoids the rigid contact between the lamp cylinder lamp shade 100 and the metal mounting plate, effectively reducing the risk of stress concentration, crack propagation and other risks caused by the difference in material thermal expansion coefficient or external impact, protecting the integrity of the lampshade structure and prolonging the service life of the lamp in complex underwater environment.

[0063] Preferably, the glue outlet hole 251 is arranged on the top surface of the second protruding part 250, so that after the sealant is discharged from the glue outlet hole 251, it can naturally spread to both sides along the top surface of the second protruding part 250 under the action of thrust and gravity, and can flow more smoothly and uniformly into the area where the first sealing groove and the second sealing groove are located, ensuring that the mating interface is fully wrapped and filled with sealant, and avoiding local lack of glue or air gap.

[0064] This layout optimizes the flow path of the sealant, uses the planar expansion characteristics of the top surface to achieve natural flow and full coverage of the glue, significantly improves the filling quality of the double-sealing groove area, enhances the bonding strength and waterproof continuity between the sealing ring and the surrounding structure, effectively prevents water from penetrating along the edge of the sealing ring, and further improves the reliability and durability of the overall sealing.

[0065] In addition, the top surface of the second protruding part 250 is also provided with an exhaust hole 252, which is symmetrically arranged with the glue outlet hole 251, so that during the glue injection process, the gas can smoothly flow out of the exhaust hole 252, ensuring smooth glue injection.

[0066] Preferably, the distance between the lamp cylinder light source module 110 and the lamp cylinder lampshade 100 forms an air flow channel for heat dissipation and sealing detection, and the first air hole 201 and the second air hole 211 are respectively arranged on the end surface of the upper mounting plate 200 and the lower mounting plate 210 away from the lamp cylinder assembly 100.

[0067] Specifically, the first air hole 201 and the second air hole 211 are configured as:

[0068] Sealing inspection: immerse the lamp in water, inject gas through one of the air holes, if the lamp is not sealed well, the gas will escape from the leakage point and form visible bubbles in the water, thereby achieving intuitive judgment of the sealing performance;

[0069] To improve the heat dissipation effect: both air holes are opened, dry helium gas is injected into the air flow channel to expel the internal air and complete helium replacement, and after a period of inflation, the two air holes are closed, so that the lamp interior is filled with dry helium gas and maintains a slightly positive pressure state.

[0070] Because the thermal conductivity of helium is better than that of air, when the lamp body works and heats up, the air flow channel filled with helium can more effectively transfer the heat generated by the light source module to the inner wall of the lamp cylinder lampshade 100 through gas convection, and then exchange heat with the external water body, thereby improving the overall heat dissipation efficiency.

[0071] Overall, by setting the first air hole 201 and the second air hole 211 in communication with the air flow channel, and combining the water gas tightness detection method, the sealing performance of the lamp can be intuitively, efficiently and reliably verified under the simulation conditions of the actual use environment, and at the same time, the structure takes into account the internal air replacement function to improve the heat dissipation effect, realizing a multifunctional sealing design of "detectable, dischargeable and preventable", and significantly enhancing the environmental adaptability and long-term operation reliability of the underwater fishing lamp.

[0072] In addition, when the first air hole 201 and the second air hole 211 need to be closed, the scheme adopts a triple-sealing closure method: first, screw an M4 mechanism screw into the air hole to preliminarily block the hole and press the sealing surface; then, inject a small amount of sealant through the gap between the screw and the air hole, so that the glue penetrates into the threaded joint, fills the small gap, and enhances the sealing continuity; finally, tighten the waterproof sealing screw to realize the final mechanical sealing by using its precise fit and the pressing effect of the sealing ring and the end surface.

[0073] Through the combined sealing method of "M4 mechanism screw + sealant injection + waterproof sealing screw", triple redundancy protection is realized at the air hole closure position, significantly improving the sealing level of this potential leakage point.

[0074] The method takes into account the operation feasibility and sealing reliability, meets the detection function requirement in the production process, ensures the complete sealing of the air hole in the final use state, and eliminates the risk of leakage due to vibration, pressure difference or material aging in long-term use. It is especially suitable for underwater fishing lamps in high-pressure deep water environment, effectively ensuring the internal dry environment and electrical safety, and further enhancing the durability and environmental adaptability of the whole lamp.

[0075] Preferably, the upper mounting plate 200 is further provided with a wire containing groove 202 on the end face away from the lamp barrel assembly 100, which is used to accommodate the power supply wire led out from the inside of the lamp body, and the gap between the wire and the groove wall is completely sealed by filling sealant, effectively avoiding the risk of capillary penetration of moisture between the wire and the shell, significantly improving the waterproof reliability of the lead area, cooperating with the overall glue injection process, making the wire sealing and other sealing areas work together, further perfecting the omnidirectional waterproof system of the lamp, and greatly improving the safety and durability of the lamp in deep water, high pressure and complex dynamic environment.

[0076] Preferably, the upper mounting plate 200 is further provided with a wire containing groove 202 on the end face away from the lamp barrel assembly 100, which is used to accommodate the power supply wire led out from the inside of the lamp body, and the gap between the wire and the groove wall is completely sealed by filling sealant, effectively avoiding the risk of capillary penetration of moisture between the wire and the shell, significantly improving the waterproof reliability of the lead area, cooperating with the overall glue injection process, making the wire sealing and other sealing areas work together, further perfecting the omnidirectional waterproof system of the lamp, and greatly improving the safety and durability of the lamp in deep water, high pressure and complex dynamic environment.

[0077] The rope mounting seat 300 is mainly used for mounting the rope to realize the suspension and positioning of the fishing lamp during operation, and can also prevent foreign matters from entering the airflow channel between the lamp barrel light source module and the lamp barrel lampshade, avoiding the blockage of internal channels by mud, marine organisms or net fragments, affecting the heat dissipation efficiency or gas replacement effect, so as to ensure the cleanliness and heat management performance stability of the lamp internal environment.

[0078] Further, the rope mounting seat 300 in the embodiment is designed in a conical structure. The conical head design not only has a good streamline shape, can quickly slide through the fishing net gap in water, effectively avoids being caught or entangled by the mesh, improves the deployment and recovery efficiency, but also plays a role in breaking water when the lamp is towed with the ship, reduces the water flow resistance, reduces the vibration and swing amplitude, and improves the operation stability.

[0079] At the same time, the front end of the conical structure of the rope mounting seat 300 has certain strength and directivity, can slightly support the fishing net fiber, realizes the "self-unhooking" function, further reduces the risk of hanging net, and is suitable for continuous operation in complex fishing ground environment.

[0080] The bottom base 400 has a containing cavity and is used for mounting the bottom light source 500, and the downward directional light supplement is realized through the bottom light source 500, forming a “circumferential + downward” composite lighting mode. The design can effectively expand the light coverage range of the lamp, enhance the penetration of the lower water area, especially suitable for attracting fish that move phototactically from the bottom or obliquely downward, significantly improving the fish collecting efficiency and operation adaptability.

[0081] Further, the containing cavity includes an inner mounting groove 410 and an outer mounting groove 420, the outer mounting groove 420 is connected with the inner mounting groove 410 and is connected through a stepped surface, and the bottom light source 500 includes a bottom light source module 510 and a bottom light source protective glass 520, the bottom light source module 510 is arranged in the inner mounting groove 410, and the bottom light source protective glass 520 is mounted on the outer mounting groove 420 and forms a sealing fit with the bottom base 400, so as to encapsulate the bottom light source 500 as a whole in the containing cavity.

[0082] The stepped surface transition structure design of the inner mounting groove 410 and the outer mounting groove 420 realizes the layered installation and accurate positioning of the bottom light source module 510 and the bottom light source protective glass 520, and ensures the stable and reliable assembly process.

[0083] It is worth mentioning here that in the embodiment, the bottom base 400 is provided with an inner recessed clamping groove 430 on the inner side wall of the outer mounting groove 420, and when the bottom light source protective glass 520 is mounted on the outer mounting groove 420, a certain gap is reserved between the side wall of the bottom light source protective glass 520 and the inner side wall of the bottom base 400, forming an annular glue injection space, and the clamping groove 430 is connected with the glue injection space to form a continuous common glue injection area.

[0084] Therefore, after the bottom light source protective glass 520 is assembled in place, the sealing glue is injected into the glue injection area, the glue can fill the glue injection space and flow into the inner clamping groove 430 at the same time, and after solidification, an integrated glue sealing structure is formed. The design organically combines mechanical clamping and glue sealing, significantly improves the connection strength and waterproof reliability of the bottom light source protective glass 520, and the sealing glue filled in the glue injection space effectively seals the gap between the bottom light source protective glass 520 and the base, preventing water from penetrating into the inside along the mating surface.

[0085] At the same time, after the glue solidifies into the clamping groove 430, a “glue nail” effect is formed, which produces a mechanical anchoring effect, greatly enhances the pull-out resistance and vibration resistance of the lampshade, avoids the lampshade from loosening due to water flow impact or external force impact, and further improves the overall safety and durability of the fish collecting lamp.

[0086] In addition, to further improve the sealing effect, during assembly, the contact part of the bottom light source protective glass 520 and the step surface of the outer mounting groove 420 is fixed by local point gluing with low viscosity and fast curing pre-adhesive glue, realizing the preliminary positioning and gap sealing of the lampshade.

[0087] The pre-adhesive process can effectively block the initial gap between the bottom light source protective glass 520 and the bottom base 400 before formal glue injection, preventing subsequent injection of the main sealing glue from leaking or producing voids. After the pre-adhesive glue is preliminarily cured, the main sealing glue is uniformly injected into the entire common glue injection area (including the glue injection space and the clamping groove 430), ensuring that the glue fully fills all the connecting interfaces.

[0088] During the glue injection process, the sealing glue not only completely fills the common glue injection area, but also naturally extends outward to cover the outer surface root area of the bottom light source protective glass 520, forming a continuous sealing coating. This coating completely wraps the connection between the lampshade and the base, further lengthening the path of water vapor intrusion and enhancing the waterproof barrier capability of the interface.

[0089] The two-stage sealing process of "pre-adhesive + main glue injection" significantly improves the reliability and sealing integrity of the bottom light source protective glass 520 packaging. The pre-adhesive glue effectively prevents the main sealing glue from infiltrating or uneven filling, ensuring the controllability and consistency of the glue injection process.

[0090] The main sealing glue not only realizes mechanical anchoring and sealing functions, but also forms an "outer sealing edge" structure on the outer surface of the lampshade, which further builds an additional waterproof line, greatly reducing the risk of sealing cracking caused by vibration, thermal cycling or external impact.

[0091] The overall structure combines the clamping groove 430 and the common glue injection area, realizing "mechanical locking - glue anchoring - surface sealing" three-level protection, making the bottom light source 500 area have excellent waterproof, anti-dropping and durability performance, especially suitable for underwater fishing lights that work in high pressure and strong water flow environment for a long time, and improving the sealing level and operation reliability of the product.

[0092] Preferably, it also includes a power distribution box 600, which is connected to the hanging rope mounting seat 300 and an external power source through the first cable 610 and the second cable 620 at both ends, and the first cable 610 and the second cable 620 are detachably connected to the power distribution box 600.

[0093] It should be noted that the design of adding a power distribution box 600 and using a segmented cable structure is mainly for cost optimization and maintenance convenience:

[0094] On the one hand, some users have long-distance power supply cables (i.e., the second cable 620) that meet the specifications in actual applications, and the length of the cable can usually reach tens of meters. By providing a detachable power distribution box 600, the manufacturer only needs to provide the combination of the fishing lamp main body + the first cable 610 + the power distribution box 600 to such users, and the second cable 620 can be directly used by the user, avoiding repeated purchase of long cables and significantly reducing procurement costs, especially in large-scale deployment scenarios.

[0095] On the other hand, since the second cable 620 is long, is laid in a complex environment for a long time, and bears a large tension, it is prone to wear and tear. Once the traditional integrated cable is damaged, it often needs to be replaced as a whole, which is high in maintenance cost and affects the continuity of work. The present application realizes modular connection through the power distribution box 600. When the second cable 620 is worn or fails, it only needs to be detached from the power distribution box 600 and replaced with a new cable, without the need to disassemble the lamp main body or replace the internal circuit, which greatly improves the maintenance efficiency and use flexibility.

[0096] The power distribution box 600 and the segmented detachable cable structure realize the modularization, standardization and scalability design of the fishing lamp power supply system, not only supporting users to configure and flexibly select as needed, reducing the initial investment cost, but also significantly improving the maintainability and economy of the equipment in long-term operation.

[0097] At present, the conventional fishing lamp is connected only by the bolts 260 arranged at intervals between the upper mounting plate 200 and the lower mounting plate 210. Although this structure can ensure the structural stability of the lamp under normal working conditions, it lacks external protection and has poor impact resistance and drop resistance.

[0098] When the fishing lamp is accidentally dropped during transportation or deployment, since the lamp barrel and lamp shade 110 and the bottom light source protective glass 520 are usually made of glass materials with excellent light transmission, the impact resistance is weak, and the glass is easily broken due to direct contact with the ground or collision, resulting in seal failure or damage to the light source.

[0099] To solve this problem, the present application provides the following improvements:

[0100] A plurality of annular plates 270 are arranged at intervals on the annular end face of each bolt 260 and are connected to form a cage-shaped protective structure surrounding the lamp barrel assembly. The cage-shaped structure is composed of a plurality of annular plates 270 and is uniformly distributed around the lamp barrel. When the lamp is dropped, the cage-shaped structure can first contact the ground, play a buffering and supporting role, effectively disperse the impact force, avoid the lamp barrel and lamp shade 110 being directly stressed, and significantly improve the overall drop resistance and mechanical protection capability.

[0101] Meanwhile, the outwardly extending protrusion 440 is arranged on the bottom end face of the bottom base 400, the height of the protrusion 440 is greater than the outer convex height of the bottom light source protection glass 520, so that when the lamp bottom is grounded, the protrusion 440 is first contacted with the ground, thereby prolonging the distance between the protection glass 520 and the ground, and forming physical limiting protection. The design greatly reduces the risk of breaking the protection glass due to bottom impact, further improving the durability and safety of the lamp in actual use.

[0102] In summary, by adding the cage-shaped protection structure and the bottom protrusion, the key optical components are comprehensively mechanically protected, the anti-falling and anti-impact capability of the fish collecting lamp in a complex operation environment is significantly enhanced, the service life of the product is effectively prolonged, and the maintenance cost is reduced.
