Abstract

This utility model discloses an emergency buoy deployment device, belonging to the field of buoy deployment. It includes a fixing mechanism, with a main body mechanism installed above the side of the fixing mechanism. The deployment mechanism is installed inside the main body mechanism. The key technical point is that by engaging an electric push rod inside a positioning groove, when the electric lifting rod moves downwards, the electric push rod applies force to the deployment plate, causing the deployment plate to move downwards as well. This allows the compression spring to store energy. After the compression spring has completed its energy storage, the rolling roller, during the retraction of the electric push rod, buffers the resistance of the compression spring on the deployment plate, allowing the electric push rod to quickly leave the upper end of the deployment plate. At this time, the stored energy force of the compression spring causes the deployment plate to quickly spring upwards, deploying the buoy. After deployment, the electric lifting rod drives the assembly plate to move the electric push rod upwards, locking it at the upper end of the deployment plate, repeating the deployment operation. This structure avoids manual intervention during emergency buoy deployment and effectively improves the efficiency of emergency buoy deployment.

Description

Technical Field

[0001] This utility model relates to the field of buoy casting, and in particular to an emergency buoy casting device. Background Technology

[0002] Buoys, as key equipment for navigational markers and marine rescue, need to be deployed quickly and continuously in emergency scenarios (such as channel blockages and ship grounding rescues). Existing buoy deployment methods are mainly divided into two categories: 1. Manual deployment, which is affected by the turbulence of the emergency vessel, resulting in low deployment efficiency (approximately 1 buoy per minute) and poor safety; 2. Automatic deployment equipment, which solves the problem of manual intervention, but has the following drawbacks: ① Lack of a continuous feeding structure, requiring frequent manual replenishment of the deployment cylinder, leading to deployment interruptions (replenishment is required every 3 buoys deployed, with an interruption time > 40 seconds); ② High contact resistance between the push rod and the deployment plate of the deployment mechanism, causing sluggish operation and affecting emergency response speed; ③ Fixed angle after installation, unable to adapt to deployment needs in different directions, and prone to swaying when the vessel is turbulent, reducing deployment accuracy. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an emergency buoy casting device. By setting an electric push rod and an electric lifting rod, and with the repeated use of the compression spring, manual intervention is avoided during emergency buoy casting, and the efficiency of emergency buoy casting is effectively improved.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An emergency buoy deployment device includes a fixing mechanism, a main body mechanism installed above the side of the fixing mechanism, and a deployment mechanism installed inside the main body mechanism.

[0006] The throwing mechanism includes an electric lifting rod, an assembly plate fixedly installed at the upper end of the electric lifting rod, an electric push rod fixedly installed at the front end of the assembly plate, a rolling roller fixedly installed at the lower end of the electric push rod, a limit plate fixedly installed on the side of the upper end of the electric lifting rod, and a feeding groove opened in the middle of the limit plate. The rolling roller installed at the lower end of the electric push rod reduces the resistance when the electric push rod moves and improves the smoothness of the electric push rod's movement.

[0007] Furthermore, the fixing mechanism includes a base plate, bolts are installed on the internal threads of the side of the base plate, a rotating shaft is fixedly installed in the middle of the upper part of the base plate, an extension frame is fixedly installed at the outer end of the rotating shaft, and a counterweight is fixedly installed at the upper end of the rotating shaft.

[0008] Furthermore, the main structure includes a casting cylinder with a feed inlet in the middle. A guide trough is fixedly installed on the outer end of the casting cylinder outside the feed inlet. A compression spring is fixedly installed on the inner end of the casting cylinder, and a casting plate is fixedly installed on the upper end of the compression spring. A positioning groove is provided on the upper side of the casting plate. The feed inlet allows the buoy to be automatically fed during casting, avoiding manual feeding. Therefore, it saves a lot of time and improves the efficiency of casting buoys in emergency situations.

[0009] Furthermore, the electric lifting rod is fixedly installed on the side of the inner end of the throwing cylinder. The electric lifting rod corresponds to the feed inlet. There are two electric lifting rods. One of them is located in the middle of the inner end of the feed inlet and a limiting plate is installed at its upper end. The other is installed opposite the feed inlet to keep the throwing plate installed on the electric lifting rod balanced. The electric lifting rod drives the throwing plate to move downward, so that the compression spring at the lower end of the throwing plate accumulates and stores energy, which provides the throwing power for the buoy.

[0010] Furthermore, the electric push rod and the positioning groove are adapted to each other, and the rolling rollers are equidistantly distributed in front of the lower end of the electric push rod.

[0011] Furthermore, the limiting plate has an arc-shaped structure, the limiting plate fits the inner end of the throwing cylinder and is movably installed, and the feeding groove and the feeding port correspond to each other.

[0012] Furthermore, the throwing cylinder is fixedly installed at the upper end of the extension frame, and the guide trough has a U-shaped structure.

[0013] Furthermore, the compression springs are equidistantly distributed in the middle of the inner end of the throwing tube, and the positioning grooves are symmetrically distributed on the upper side of the throwing plate.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. By locking the electric push rod inside the positioning slot, when the electric lifting rod moves downward, the electric push rod applies force to the throwing plate, causing the throwing plate to move downward as well. This allows the compression spring to store energy. After the compression spring has completed storing energy, the rolling roller buffers the resistance brought by the compression spring to the throwing plate during the retraction of the electric push rod, allowing the electric push rod to quickly leave the upper part of the throwing plate. At this time, the stored elastic force of the compression spring causes the throwing plate to bounce upward quickly, throwing the buoy out. After the throwing is completed, the electric lifting rod drives the assembly plate to move the electric push rod upward and lock it at the upper end of the throwing plate, repeating the throwing operation. This structure avoids manual intervention during emergency buoy throwing and effectively improves the efficiency of emergency buoy throwing.

[0016] 2. By setting the limiting plate to fit inside the casting tube and overlapping with the feed inlet, when the casting plate is in normal condition, the buoy enters the upper part of the casting plate inside the casting tube from the feed inlet. As the electric lifting rod moves, the feed groove and feed inlet in the middle of the limiting plate form a misaligned structure, which prevents other buoys from entering the interior of the casting tube, thus not affecting the buoys waiting to be cast.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0025] Reference Figure 1-5 As shown, a buoy emergency launching device is provided in a preferred embodiment of the present invention, including a fixing mechanism 1, a main body mechanism 2 installed on the upper side of the fixing mechanism 1, and a launching mechanism 3 installed inside the main body mechanism 2.

[0026] The throwing mechanism 3 includes an electric lifting rod 301. An assembly plate 302 is fixedly installed on the upper end of the electric lifting rod 301. An electric push rod 303 is fixedly installed on the front end of the assembly plate 302. A rolling roller 304 is fixedly installed on the lower end of the electric push rod 303. A limiting plate 305 is fixedly installed on the side of the upper end of the electric lifting rod 301. A feeding groove 306 is opened in the middle of the limiting plate 305. The rolling roller 304 is installed on the lower end of the electric push rod 303 to reduce the resistance when the electric push rod 303 moves and improve the smoothness of the electric push rod 303's movement.

[0027] The fixing mechanism 1 includes a base plate 101, with bolts 102 installed on the internal threads of the side of the base plate 101. A rotating shaft 103 is fixedly installed in the middle of the upper end of the base plate 101. An extension frame 104 is fixedly installed at the outer end of the rotating shaft 103. A counterweight 105 is fixedly installed at the upper end of the rotating shaft 103. The rotating shaft 103 allows the device to operate at multiple angles. The counterweight 105 increases the weight of the mechanism and avoids the problem of gravity imbalance.

[0028] The main body 2 includes a launching cylinder 201. A feed inlet 202 is provided in the middle of the launching cylinder 201. A guide groove 203 is fixedly installed on the outer end of the launching cylinder 201 outside the feed inlet 202. A compression spring 204 is fixedly installed on the inner end of the launching cylinder 201. A launching plate 205 is fixedly installed on the upper end of the compression spring 204. A positioning groove 206 is provided on the side of the upper end of the launching plate 205. The feed inlet 202 enables the float to be automatically fed during launching, avoiding manual feeding. Therefore, it saves a lot of time and improves the efficiency of launching floats in emergency situations.

[0029] The electric lifting rod 301 is fixedly installed on the side of the inner end of the throwing cylinder 201. The electric lifting rod 301 corresponds to the feed inlet 202. There are two electric lifting rods 301. One of them is located in the middle of the inner end of the feed inlet 202 and a limiting plate 305 is installed on its upper end. The other is installed opposite the feed inlet 202 to keep the throwing plate 205 installed on the electric lifting rod 301 balanced. The electric lifting rod 301 drives the throwing plate 205 to move downward, so that the compression spring 204 at the lower end of the throwing plate 205 accumulates and stores energy, which provides the power to throw the buoy.

[0030] The electric push rod 303 is compatible with the positioning groove 206. The rolling rollers 304 are evenly distributed in front of the lower end of the electric push rod 303. The electric push rod 303 is locked inside the positioning groove 206. When the electric lifting rod 301 moves downward, the electric push rod 303 applies force to the throwing plate 205, causing the throwing plate 205 to move downward as well. This allows the compression spring 204 to store energy. After the compression spring 204 has completed storing energy, the rolling rollers 304 buffer the resistance brought by the compression spring 204 to the throwing plate 205 as the electric push rod 303 retracts, allowing the electric push rod 303 to quickly leave the upper end of the throwing plate 205. At this time, the stored elastic force of the compression spring 204 causes the throwing plate 205 to spring upward quickly, throwing the buoy out. After the throwing is completed, the electric lifting rod 301 drives the assembly plate 302 to move the electric push rod 303 upward and lock it at the upper end of the throwing plate 205, repeating the throwing operation.

[0031] The limiting plate 305 has an arc-shaped structure. The limiting plate 305 fits against the inner end of the launching tube 201 and is movably installed. The feed chute 306 and the feed inlet 202 correspond to each other. The limiting plate 305 fits against the inside of the launching tube 201 and overlaps with the position of the feed inlet 202. When the launching plate 205 is in normal state, the buoy enters the upper end of the launching plate 205 inside the launching tube 201 from the feed inlet 202. As the electric lifting rod 301 moves, the feed chute 306 and the feed inlet 202 in the middle of the limiting plate 305 form a misaligned structure, that is, it isolates other buoys from entering the inside of the launching tube 201, so as not to affect the buoys waiting for launching operations.

[0032] The launching tube 201 is fixedly installed on the upper end of the extension frame 104. The guide trough 203 has a U-shaped structure. The U-shaped guide trough 203 can hold multiple buoys waiting for operation, so that the device can continuously launch buoys and prevent the buoys from falling off during placement.

[0033] Compression springs 204 are evenly distributed in the middle of the inner end of the casting tube 201, and positioning grooves 206 are symmetrically distributed on the upper side of the casting plate 205. Compression springs 204 use high elasticity springs and multiple springs are set to transform quantitative change into qualitative change, meet the energy consumption required for casting buoys, and in use, the casting distance of the buoy can be kept constant by calculating the amount of energy stored in the compression springs 204.

[0034] The rotating shaft 103 has a rotation angle of 0-180°, and a brake pad is provided on the outer side of the rotating shaft 103. The weight ratio of the counterweight 105 to the base plate 101 is 1:3. The guide trough 203 is a U-shaped stainless steel trough with an opening width of 5cm, a length of 30cm, and a depth of 4cm. The inner wall of the guide trough 203 is chrome-plated with a roughness Ra≤0.8μm. The compression spring 204 is a cylindrical helical spring made of 60Si2Mn material with an elastic coefficient of 50N / mm and a compression stroke of 10cm. There are three compression springs 204, which are distributed in an equilateral triangle at the bottom of the inner end of the throwing cylinder 201. The cross-sectional shape of the electric push rod 303 is the same as that of the positioning groove 206, both being rectangular. The gap between the electric push rod 303 and the positioning groove 206 is ≤0.5mm. The rolling roller 304 is made of polyurethane material, with a diameter of 2cm and a length of 3cm, and is evenly distributed at the lower end of the electric push rod 303 with a spacing of 2cm. The limiting plate 305 is an arc-shaped stainless steel plate with a radius consistent with the inner diameter of the throwing cylinder 201. The feeding trough 306 is a rectangular trough with a width of 5cm, corresponding to the feeding port 202. The electric lifting rod 301 is a DT300 model with a maximum stroke of 15cm. There are two electric lifting rods 301, symmetrically distributed on both sides of the inner end of the throwing cylinder 201, each 15cm from the center of the throwing cylinder 201. The bolts 102 are M12 stainless steel bolts, a total of four, evenly distributed at the four corners of the base plate 101.

[0035] Specific implementation process: This utility model is an emergency buoy deployment device. First, the device is installed on an emergency boat via a base plate 101. The direction of buoy deployment is adjusted via a rotating shaft 103. A deployment cylinder 201 is installed at the upper end of an extension frame 104 mounted on the outer end of the rotating shaft 103. The feed inlet 202 in the middle of the deployment cylinder 201 and the guide trough 203 installed at the outer end are aligned. The buoys to be deployed are positioned one by one inside the guide trough 203. Two electric motors are installed at the inner end of the deployment cylinder 201. The lifting rod 301 has two parts: one located in the middle of the inner end of the feed inlet 202, with a limiting plate 305 installed at its upper end; the other is installed opposite the feed inlet 202, ensuring the throwing plate 205 mounted on the electric lifting rod 301 is balanced. The electric push rod 303 at the upper end of the electric lifting rod 301 is engaged inside the positioning groove 206. When the electric lifting rod 301 moves downward, the electric push rod 303 applies force to the throwing plate 205, causing it to move downward as well. This allows the compression spring 204 to store energy. After the spring 204 completes its energy storage, the rolling roller 304, during the retraction of the electric push rod 303, buffers the resistance of the compression spring 204 on the throwing plate 205, allowing the electric push rod 303 to quickly move away from the top of the throwing plate 205. At this time, the stored elastic force of the compression spring 204 causes the throwing plate 205 to spring upwards rapidly, throwing the buoy out. After the throwing is completed, the electric lifting rod 301 drives the assembly plate 302 to move the electric push rod 303 upwards, locking it at the top of the throwing plate 205, repeating the throwing operation. The various components of this device complement each other. Furthermore, a limiting plate 305 is also provided. The limiting plate 305 fits against the inside of the throwing tube 201 and overlaps with the position of the feed inlet 202. When the throwing plate 205 is in normal state, the buoy enters the upper part of the throwing plate 205 inside the throwing tube 201 from the feed inlet 202. As the electric lifting rod 301 moves, the feed groove 306 opened in the middle of the limiting plate 305 and the feed inlet 202 form a misaligned structure, that is, it isolates other buoys from entering the inside of the throwing tube 201, so as not to affect the buoys waiting for the throwing operation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
