Description

Technical Field

[0001] This invention relates to the field of buoyancy block technology, and in particular to a buoyancy block that can realize a quick opening and closing locking function. Background Technology

[0002] In the use of marine towed cables, in order to adjust the specific gravity of the towed cable, buoyancy blocks are usually added to the towed cable.

[0003] In existing technologies, the installation of buoyancy blocks is usually done manually. The buoyancy blocks are manually tied to the specific locations to be installed. The tying methods can generally be divided into: first fixing the prefabricated component to the towing cable, and then connecting the buoyancy block to the prefabricated component by binding; or setting screw holes on the buoyancy block and using screws to fix the buoyancy block to the prefabricated component; or setting grooves on the outer circle of the buoyancy block and using clamps to fix the buoyancy block to the prefabricated component.

[0004] However, the above methods all have the problems of high labor consumption, long binding process, and cumbersome disassembly and assembly process, which result in long cable laying and retrieval time. Summary of the Invention

[0005] To address the problem that the assembly and disassembly process of buoyancy blocks in existing technologies is cumbersome and time-consuming, the purpose of this invention is to provide a buoyancy block that can achieve a quick opening and closing locking function.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A buoyancy block capable of quick opening and closing locking includes two floats, each with a cable support groove on its opposite side, and the two cable support grooves interlocking to form a cable support through hole; the two floats are connected by a hinge, and the two floats are also detachably and fixedly connected by an opening and closing device, the opening and closing device including a connecting mechanism and a locking slot respectively installed on the two floats and used in conjunction.

[0008] The connecting mechanism includes a sliding rod, an elastic reset member, and a locking pin. The sliding rod is slidably connected to one of the floats, the elastic reset member is connected between the sliding rod and the one of the floats, and the locking pin is fixedly connected to the sliding rod.

[0009] The locking slot is fixedly connected to another float. The locking slot has a receiving groove for accommodating the sliding rod. A guide bevel is provided on one side of the top of the locking slot. The guide bevel is used to guide the locking pin to move along the guide direction of the guide bevel when the two floats are closed together. A locking pin groove adapted to the locking pin is provided on one end face of the locking slot connected to the guide bevel.

[0010] Preferably, a plurality of locking pins are installed at intervals along the axial direction on the sliding rod, and the same number of locking slots are installed on the other float in the same arrangement.

[0011] Preferably, the elastic reset element is a spring, and the connecting mechanism further includes a spring support sleeve, which is fixedly installed on one of the floats, and the spring is located in the spring support sleeve; the spring support sleeve is coaxially arranged on one side of the sliding rod, and one end of the sliding rod passes through the spring support sleeve.

[0012] Preferably, the connecting mechanism further includes at least two slide bar guides for guiding the sliding bar to slide, and the slide bar guides are all fixedly installed on one of the floats.

[0013] Furthermore, the cable tray is provided with an anti-slip pad.

[0014] Preferably, the anti-slip pads are made of an elastic material, and the diameter of the through holes formed by the anti-slip pads respectively disposed on the two cable trays is smaller than the diameter of the cable to be fixed, so that when the opening and closing device locks the two floats, the anti-slip pads provide an elastic force to separate the two floats from each other.

[0015] Preferably, the connecting mechanism and the locking slot are respectively disposed on opposite sides of the two floats.

[0016] Furthermore, the connecting mechanism also includes an unlocking rod fixedly connected to the sliding rod, and the float has an operating hole for exposing the unlocking rod.

[0017] Preferably, there are two unlocking rods, which are respectively connected to the two ends of the sliding rod, and the two ends of the float are respectively provided with the operation hole.

[0018] Preferably, the operating hole and the cable support hole are coaxially arranged.

[0019] The beneficial effects of the present invention using the above technical solution are as follows: Due to the hinged connection between the two floats and the opening / closing device positioned between them, when installing the buoyancy block on the cable, only a rotational force is applied to the two floats to bring them together. Guided by the locking groove, the locking pin drives the sliding rod to compress the elastic reset member. Thus, when the locking pin is engaged in the locking groove, the elastic reset member provides a stable elastic force. When removing the buoyancy block from the cable, only a pushing force is applied to the sliding rod to disengage the locking pin from the locking groove. The buoyancy block assembly and disassembly process is simple and requires minimal manpower, thereby effectively improving the cable reeling and unloading speed. Attached Figure Description

[0036] Example 1

[0037] A buoyancy block that enables rapid opening and closing of the lock, such as Figure 1-3 As shown, the system includes two floats 1, each configured as a semi-cylindrical structure. The opposite sides (rectangular surfaces) of the two floats 1 are joined together to form a cylindrical buoyancy block. In other embodiments, the floats 1 can also be configured as rectangular blocks, thus making the buoyancy block also rectangular; this does not affect the use or the implementation of this embodiment.

[0038] Two floats 1 are each provided with a cable support groove 2 on their opposite sides. The cable support groove 2 is opened along the axial direction of the float 1 and is configured with a semi-circular cross-section. When the two floats 1 are joined together to form a buoyancy block, the two cable support grooves 2 form a cable support hole for cable insertion. In this embodiment, the cable support grooves 2 are respectively located at the center of their respective floats 1, that is, the cable support grooves 2 and the floats 1 are arranged coaxially, so that the cable support hole is also located at the center of the buoyancy block. Of course, in other embodiments, the position of the cable support groove 2 may not be located at the center of the float 1, so that the cable support hole has a certain eccentric position relative to the buoyancy block.

[0039] In this embodiment, two floats 1 are connected by hinges 3 (e.g., hinges). To enhance connection stability, two or more hinges 3 are configured and spaced apart. Furthermore, to ensure the two floats 1 maintain their overall buoyancy after docking, they are detachably and securely connected by an opening and closing device. This device includes a connecting mechanism and a locking slot, each mounted on one float 1 and used in conjunction with the other. In this embodiment, for protection of the opening and closing device, the connecting mechanism and locking slot are respectively located on opposite sides of the two floats 1, thus concealing the device when the two floats 1 are combined into a buoyancy block, achieving a protective effect. Correspondingly, to prevent the opening and closing device from affecting the fit between the opposite sides of the two floats 1, in this embodiment, recessed areas are provided on the opposite sides of each float 1 to accommodate protruding components mounted on the other float 1, thereby accommodating the protruding components. Alternatively, in other preferred embodiments, the connecting mechanism (locking groove) can be embedded on the opposite side of the float 1, so that there are no protrusions on the opposite side of the float 1.

[0040] In this embodiment, the float for installing the connection mechanism is defined as the lower float 12, and the float for installing the locking slot is defined as the upper float 11. Figure 4-5 As shown, the connecting mechanism specifically includes a sliding rod 4, an elastic reset element 5, and a locking pin 6.

[0041] The sliding rod 4 is slidably connected to the opposite side of the lower float 12 via a sliding rod guide 7. The sliding rod guide 7 is configured as a saddle buckle, which is fixedly connected to the lower float 12 by screws. The saddle buckle has a curved section, which forms a space with the opposite side of the lower float 12 to guide the sliding rod 4 to move axially. It is understood that there are at least two, for example four, sliding rod guides 7, spaced apart along the axial direction of the sliding rod 4, thereby improving the guiding effect on the sliding rod 4. Alternatively, in other embodiments, a positioning sleeve can be used instead of the saddle buckle, and the positioning sleeve can be fixed by welding.

[0042] The elastic reset element 5 is connected between the sliding rod 4 and the lower float 12 to provide a spring force for the sliding rod 4 to reset after sliding. In this embodiment, the elastic reset element 5 is configured as a helical spring, and for ease of disassembly, the connecting mechanism further includes a spring support sleeve 8. The spring support sleeve 8 is fixed to the opposite side of the lower float 12 by a semi-circular clamp and screws or adhesive, and the spring is arranged in the spring support sleeve 8. At the same time, the spring support sleeve 8 is coaxially arranged on one side (e.g., the left side) of the sliding rod 4, the left end of the spring support sleeve 8 is closed, and the left end of the sliding rod 4 passes through the spring support sleeve 8 from the right side, so that the left end face of the sliding rod 4 presses against the spring, thereby squeezing the spring between the left end of the spring support sleeve 8 and the left end of the sliding rod 4. This arrangement allows the elastic reset element 5 to provide a rightward elastic force to the sliding rod 4 after compression, and also facilitates replacement.

[0043] The locking pin 6 is fixedly connected to the sliding rod 4. For example, a pin hole is opened in the sliding rod 4, and the locking pin 6 is inserted into the pin hole, with at least one end (e.g., both ends) of the locking pin 6 protruding from the side wall of the sliding rod 4. Alternatively, the locking pin 6 can also be fixed to the sliding rod 4 by welding. Angularly, the locking pin 6 and the sliding rod 4 can be arranged to be staggered, but in this embodiment, they are preferably perpendicular to each other.

[0044] Among them, such as Figure 6-7 As shown, the locking groove 9 has an overall concave, U-shaped, or n-shaped structure. The concave part is configured as a receiving groove 91 for accommodating the sliding rod 4. A screw hole 92 is provided at the bottom of the receiving groove 91 to facilitate fixing to the opposite side of the upper float 11 with screws. A guide bevel 93 is provided on one side of the top of the receiving groove 91 along the length direction of the locking groove 9 (i.e., the length direction of the receiving groove and the length direction of the sliding rod 4). The guide bevel 93 is connected to one end face of the locking groove 9 along the length direction (i.e., the guide bevel 93 extends to one end face of the locking groove 9 along the length direction). The guide bevel 93 is used to guide the locking pin 6 to move along the guide direction of the guide bevel 93 when the two floats 1 are closed to form a buoyancy block. In addition, a locking pin groove 94 adapted to the locking pin 6 is also provided on one end face of the locking groove 9 connected to the guide bevel 93. It is understandable that the locking groove 94 is provided on the side wall end of the receiving groove 91. There are usually two locking grooves 94, that is, locking grooves 94 are provided on the two opposite side walls of the receiving groove 91, so that when both ends of the locking pin 6 protrude from the sliding rod 4, the two locking grooves 94 can fix the two ends of the locking pin 6 respectively.

[0045] In summary, the working process of the opening and closing device is as follows: Under the action of external force, the two floats 1 close together based on the hinge 3 until the locking pin 6 on the sliding rod 4 contacts the guide bevel 93. Under the guidance of the guide bevel 93, as the two floats 1 continue to close together, the locking pin 6, while sliding along the guide bevel 93, will also drive the sliding rod 4 to overcome the elastic force of the elastic reset member 5 and move axially (to the left). The axial length of the guide bevel 93 represents the axial movement distance of the sliding rod 4 (the compression length of the elastic reset member 5). When the locking pin 6 has completely slid past the guide bevel 93 and the two floats 1 continue to close together, the locking pin 6 moves along one end face of the locking groove 9 until it reaches the position of the locking pin groove 94. Under the action of the elastic force of the elastic reset member 5, the locking pin 6 is pushed into the locking pin groove 94. At this time, the two floats 1 cannot rotate relative to each other (cannot be opened), thus realizing the locking function. When the opening and closing device is activated, only a leftward thrust is applied to the sliding rod 4. After the locking pin 6 is pushed out of the locking pin groove 94, the two floats 1 can be flipped, thereby realizing the opening function of the buoyancy block.

[0046] It is understandable that the right end of the sliding rod 4 can be configured to extend to the outside of the buoyancy block, thereby enabling the unlocking operation of the opening and closing device directly through the sliding rod 4. In this embodiment, the sliding rod 4 is configured to be entirely hidden within the buoyancy block, and the connecting mechanism further includes an unlocking rod 10. The unlocking rod 10 is parallel to the sliding rod 4, and there is a certain gap between the unlocking rod 10 and the sliding rod 4. For example, the unlocking rod 10 can be connected to the sliding rod 4 via the movable connecting rod 13, or the unlocking rod 10 can be configured as an L-shape and directly connected to the sliding rod 4.

[0047] Among them, such as Figure 8 As shown, the movable link 13 has a screw hole 131 (radially opened) in the middle, and is connected to the opposite side of the lower float 12 by a screw. The diameter of the screw hole 131 is larger than the diameter of the screw to allow the movable link 13 to rotate around the screw. The upper and lower ends of the movable link 13 are hinged to the unlocking rod 10 and the sliding rod 4 respectively by pins 14. The movable link 13 has a flat structure so that the opening 101 at the end of the unlocking rod 10 for accommodating the upper end of the movable link 13 only needs to have a small width. Figure 9 As shown, correspondingly, the through groove 41 on the sliding rod 4 for accommodating the movable connecting rod 13 only needs to have a small width, such as... Figure 10As shown. In this embodiment, the end of the unlocking rod 10 is provided with a pin hole that penetrates the opening slot 101, and the sliding rod 4 is also provided with a pin hole that penetrates the through slot 41. The pin holes 132 provided at the upper and lower ends of the movable connecting rod 13 for connecting the pins 14 are configured as elongated holes so that when the unlocking rod 10 moves axially, the movable connecting rod 13 can transmit the motion to the sliding rod 4 while rotating around the screw.

[0048] The free end of the unlocking rod 10 protrudes through the operating hole 15 provided on the buoyancy block. In this embodiment, as shown... Figure 1 and Figure 2 As shown, the operating hole 15 is located at the end of the buoyancy block along its length, and the operating hole 15 is stepped and coaxially arranged with the cable guide hole. That is, its diameter is enlarged at the end of the cable guide groove 2, so that when the two floats 1 are closed, a larger diameter operating hole 15 (relative to the cable guide hole) is formed at the end of the buoyancy block. The free end of the unlocking rod 10 extends into the operating hole 15 (at a position that avoids the cable guide hole). At the same time, the unlocking rod 10 is equipped with a positioning sleeve 16, which is fixed to the lower float 12 by screws. The unlocking rod 11 passes through the positioning sleeve 16. Correspondingly, a clearance groove is opened on the opposite side of the float 1 at the position corresponding to the unlocking rod 10 (and the positioning sleeve 16) to allow the unlocking rod 10 to move.

[0049] Understandably, when there is one unlocking lever 10, it can be arranged on the left side of the sliding lever 4, providing a pulling force to the leftward movement of the sliding lever 4 when unlocking, or it can be arranged on the right side of the sliding lever 4, providing a pushing force to the leftward movement of the sliding lever 4 when unlocking; or there can be two unlocking levers 10, with the two unlocking levers 10 arranged on the left and right sides of the sliding lever 4 respectively, so that when unlocking, the two unlocking levers 10 can respectively provide a pulling force and a pushing force to the leftward movement of the sliding lever 4.

[0050] The working principle of this invention is as follows: When it is necessary to clamp the cable by using the buoyancy block, firstly, the cable is placed in the cable groove 2 of one of the floats 1 (e.g., the upper float 11). External force is applied manually to make the lower float 12 rotate and close to the upper float 11. Under the guidance of the guide slope 93, the locking pin 6 will also drive the sliding rod 4 to overcome the elastic force of the elastic reset member 5 and move axially (to the left) as it slides along the guide slope 93. When the locking pin 6 has completely slid past the guide slope 93 and the two floats 1 continue to close to each other, the locking pin 6 moves along one end face of the locking groove 9 until it moves to the position of the locking pin groove 94. Under the elastic force of the elastic reset member 5, the locking pin 6 is pushed into the locking pin groove 94. At this time, the two floats 1 cannot rotate to each other (cannot be opened), thereby realizing the locking function of the cable.

[0051] When it is necessary to remove the buoyancy block from the support cable, according to the operational requirements, a pulling force to the left is applied to the sliding rod 4 through the unlocking rod 10 arranged on the left and / or a pushing force to the left is applied to the sliding rod 4 through the unlocking rod 10 arranged on the right. At this time, the sliding rod 4 overcomes the elastic force of the elastic reset member 5, thereby pushing the locking pin 6 out of the locking pin groove 94. Then, the two floats 1 can be flipped under the action of external force, thereby realizing the opening function of the buoyancy block.

[0052] It is understandable that, such as Figure 1-3 As shown, the two floats 1 are usually provided with positioning blocks 18 and positioning holes 19 on their opposite sides so that the two floats 1 can be closed more accurately.

[0053] Example 2

[0054] In this embodiment, as Figure 1 and Figure 2 As shown, multiple locking pins 6, for example four, are installed at intervals along the axial direction on the sliding rod 4, and correspondingly, the same number of locking slots 9 are installed on the upper float 11 in the same arrangement.

[0055] This configuration allows the opening and closing device to lock the two floats 1 more effectively, and each locking pin 6 can also serve as a backup for the others, preventing the buoyancy block from failing to lock if one of them fails.

[0056] Example 3

[0057] In this embodiment, as Figure 1-3 As shown, anti-slip pads 17 are provided on the cable support groove 2. The anti-slip pads 17 are installed in the cable support groove 2 by adhesive bonding or pre-embedding. The length of the anti-slip pads 17 is configured to be less than the length of the cable support groove 2, so that the anti-slip pads 17 only need to be arranged at intervals in the cable support groove 2, thus avoiding the need to install them along the entire length, in order to save materials. Correspondingly, the anti-slip pads 17 provided on the two cable support grooves 2 are positioned opposite each other. That is, when the two floats 1 are brought together to form a buoyancy block, the anti-slip pads 17 on the two cable support grooves 2 correspond one-to-one, thereby providing friction force evenly to the cable support in the 360° circumferential direction.

[0058] The inner wall surface of the anti-slip mat 17 can be either an anti-slip texture or several protrusions that can apply a certain pressure to the cable support, such as... Figure 11 As shown.

[0059] Example 4

[0060] Based on Embodiment 4, the anti-slip pad 4 is made of an elastic material, such as rubber or silicone. The diameter of the through-hole formed by the anti-slip pads 17 respectively disposed on the two cable trays 2 is slightly smaller than the diameter of the cable to be fixed. This arrangement allows the smaller diameter anti-slip pads 17 to provide a certain compressive force to the cable when the opening and closing device locks the two floats 1, thereby providing an elastic force to separate the two floats 1. This elastic force allows the locking pin 6 to be tightly engaged in the locking pin groove 94, preventing the locking pin 6 from coming out, thus improving the locking effect of the opening and closing device. Furthermore, when the opening and closing device is opened, the elastic force provided by the anti-slip pads 17 can quickly spring the two floats 1 apart.

[0061] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
