Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and in particular to a dock gate for launching airbags and its method of use. Background Technology

[0002] Airbag launching offers a cost advantage over traditional dock launching and slipway launching methods. Most existing dock gates employ a long, box-shaped structure with ballast tanks inside. During normal use, the ballast tanks are under ballast, and the gate sits at the dock entrance to block outside water from entering the dock. When needed, water is released until the water levels inside and outside the dock are equal, then the ballast tanks are emptied, allowing the gate to float and be towed away by winches or tugboats. Watertight methods involve installing a high dock sill at the dock entrance, typically 0.6 meters or higher, with two vertical concrete foundation barriers on either side. This type of dock gate usually has a U-shaped rubber section on the left, bottom, and right sides near the dock entrance. The watertightness is achieved by maintaining a constant pressure difference between the higher water level outside and the lower water level inside the dock, compressing the rubber.

[0003] Because the watertight dock gate system for box-type docks uses a relatively high dock sill at the dock entrance, typically 0.6m or higher, such a high sill is not feasible for airbag launching slipways on slopes. An excessively high sill would cause the airbag to fall too far after reaching the sill, potentially leading to excessive stress at corners and exceeding its explosive limit. Furthermore, the excessive height of the airbag after rolling off the sill could cause the stern of the ship to fall, resulting in serious consequences. Therefore, the maximum sill height for airbag launching slipways on slopes can only be 0.2m, which is insufficient to accommodate the rubber reinforcement on the side of the dock gate closest to the sill. Therefore, a dock gate design suitable for low sills is urgently needed. Summary of the Invention

[0004] The purpose of this invention is to provide a dock gate for airbag launching and its usage method, which can be adapted to low dock thresholds.

[0005] The technical solution of the present invention: A dock gate for launching airbags into water includes a dock gate body, with first water-stop rubbers fixed to both the left and right ends of the front side of the dock gate body, and pressure-bearing pads fixed to both the left and right ends of the first water-stop rubbers on the dock gate body; the bottom of the dock gate body has a placement groove, and a second water-stop rubber is fixed in the placement groove. The front end of the first water-stop rubber extends beyond the pressure pad; the bottom of the second water-stop rubber extends beyond the placement groove; The placement groove is U-shaped, and the vertical end of the placement groove penetrates the dock gate body; the vertical end of the second water-stop rubber extends beyond the dock gate body; The lower end of the first water-stopping rubber extends beyond the bottom of the dock gate body.

[0006] Furthermore, the first water-stop rubber has first studs arranged longitudinally at equal intervals at both ends, and the rear end of the first studs penetrates the first water-stop rubber and is fixed to the dock body; the first studs are provided with a first pressure strip and a first washer, and are fixed by a first nut.

[0007] Furthermore, the front side of the pressure pad is provided with mounting grooves at equal intervals in the longitudinal direction, and a third stud is provided in the mounting groove. The rear end of the third stud penetrates the mounting groove and is fixed to the dock body. A third washer is provided on the third stud and is fixed by a third nut.

[0008] Furthermore, multiple second studs are provided at equal intervals at both ends of the second water-stop rubber. The upper end of the second stud penetrates the second water-stop rubber and is fixed to the placement groove. A second pressure strip and a second washer are provided on the second stud and fixed by a second nut.

[0009] Furthermore, the pressure pad is made of MGE engineering plastic alloy.

[0010] Furthermore, the top left and right ends of the dock gate body are respectively connected to the top of the concrete retaining walls on both sides via the first spiral buckle; one end of the first spiral buckle is connected to the dock gate body 1 via the first ear plate A, and the other end is connected to the concrete retaining wall via the first ear plate B. The front side of the dock gate body is connected to the dock sill via a second spiral buckle. One end of the second spiral buckle is connected to the dock gate body via a second ear plate A, and the other end is connected to the installation pit of the dock sill via a steel wire rope and a second ear plate B.

[0011] Furthermore, the upper end of the dock gate body is box-shaped, the rear end is a water baffle, and the front end has a horizontal T-shaped profile and a vertical T-shaped profile. The upper and lower ends of the vertical T-shaped profile are connected to the dock gate body via triangular elbow plates.

[0012] Furthermore, the bottom flat iron of the dock gate body has a notch, and the placement groove is formed by a plurality of fixing plates fixed to the notch.

[0013] Furthermore, the second water-stop rubber includes a transversely arranged transverse water-stop rubber and a longitudinally arranged longitudinal water-stop rubber located at both ends of the transverse water-stop rubber.

[0014] A method for using a dock gate for airbag launching is as follows: Step 1: Place the first water-stop rubber on both sides against the concrete retaining walls on both sides of the dock opening. When the first water-stop rubber and the concrete retaining wall are squeezed, the first water-stop rubber is in an elastic deformation state, and a watertight state is formed between the first water-stop rubber and the concrete retaining wall. Step 2: During further compression, the pressure pad contacts the concrete retaining wall and forms a pressure-bearing effect to prevent the first water-stop rubber from being further compressed and potentially causing plastic deformation and damage. Step 3: After the second water-stop rubber comes into contact with the ground, it is squeezed into an elastic deformation state, and a watertight state is formed between the second water-stop rubber and the ground; Step 4: The lower end of the first water-stop rubber extends into contact and presses against the vertical end of the second water-stop rubber, thereby achieving a watertight seal; at the same time, the lower end of the first water-stop rubber also presses against the ground, creating a watertight seal between the first water-stop rubber and the ground.

[0015] The beneficial effects of this invention are: (1) Place the first water-stop rubber on both sides against the concrete retaining walls on both sides of the dock opening. When the first water-stop rubber and the concrete retaining wall are squeezed, the first water-stop rubber is in an elastic deformation state, and a watertight state is formed between the first water-stop rubber and the concrete retaining wall. When they are squeezed further, the pressure pad contacts the concrete retaining wall and forms a pressure effect, preventing the first water-stop rubber from being further squeezed and possibly forming plastic deformation and causing damage.

[0016] (2) The first and second spiral buckles can apply pressure from the dock gate body to the concrete retaining wall even when there is no water pressure behind the dock gate body, thereby ensuring that the first water-stop rubber is in a compressed state. At the same time, it can also ensure that the dock gate body will not tilt outward due to the typhoon.

[0017] (3) The box-shaped structure at the upper end of the dock gate increases the section modulus of bending and reduces the draft of the box, thus avoiding excessive buoyancy that could cause the dock gate to float and leak. The horizontal and vertical T-shaped profiles can increase the section modulus of bending and reduce the weight of the box-shaped structure, while also reducing buoyancy to avoid excessive buoyancy that could cause the dock gate to float and leak. The triangular elbow plate realizes the transfer of force at the end of the vertical T-shaped profile and prevents stress concentration.

[0018] (4) The notch can both transmit the force of the placement groove and avoid the problem that the narrow space on both sides of the placement groove is inconvenient for welding and the welding quality is poor.

[0019] In summary, this invention can be used on airbag launching slipways, is compatible with low dock thresholds, and can withstand typhoon attacks. Attached Figure Description

Detailed Implementation

[0022] The invention will now be further described with reference to the accompanying drawings.

[0023] Please see Figures 1-13 The present invention provides a first embodiment of a dock gate for airbag launching, comprising a dock gate body 1, wherein a first water-stop rubber 2 is fixed at both the left and right ends of the front side of the dock gate body 1, and a pressure-bearing pad 3 is fixed at both the left and right ends of the first water-stop rubber 2 on the dock gate body 1; the bottom of the dock gate body 1 has a placement groove 12, and a second water-stop rubber 4 is fixed in the placement groove 12.

[0024] The front end of the first waterproof rubber 2 extends beyond the pressure pad 3. The bottom of the second waterproof rubber 4 extends beyond the placement groove 12.

[0025] The first water-stop rubber 2 on both sides is placed against the concrete retaining walls 100 on both sides of the dock opening. When the first water-stop rubber 2 and the concrete retaining wall 100 are pressed together, the first water-stop rubber 2 is in an elastic deformation state, and a watertight state is formed between the first water-stop rubber 2 and the concrete retaining wall 100. When they are pressed further, the pressure pad 3 contacts the concrete retaining wall 100 and forms a pressure-bearing effect, preventing the first water-stop rubber 2 from being further compressed and potentially causing plastic deformation and damage.

[0026] Because the dock sill 200 is relatively low, with a maximum height of only 0.2m, while the width of the water-stop rubber and the two pressure pads is over 0.4m, installing the water-stop rubber and the two pressure pads on the side of the dock gate near the dock sill would exceed the dock sill's range and fail to achieve a watertight effect. Therefore, the side of the dock gate body 1 near the dock sill cannot accommodate the water-stop rubber and pressure pads 3. Thus, a placement groove 12 is created at the bottom of the dock gate body 1 to install the second water-stop rubber 4. When the second water-stop rubber 4 contacts the ground, it is compressed and undergoes elastic deformation, creating a watertight seal between the second water-stop rubber 4 and the ground.

[0027] The placement groove 12 is U-shaped, and the vertical end of the placement groove 12 penetrates the dock gate body 1 so that the vertical end of the second water-stop rubber 4 can extend beyond the dock gate body 1; the vertical end of the second water-stop rubber 4 extends beyond the dock gate body 1 so as to facilitate connection with the lower end of the first water-stop rubber 2.

[0028] The lower end of the first water-stop rubber 2 extends beyond the bottom of the dock body 1, so that the connection between the lower end of the first water-stop rubber 2 and the second water-stop rubber 4 is watertight.

[0029] The lower end of the first water-stop rubber 2 extends into contact with and presses against the vertical end of the second water-stop rubber 4, thus achieving a watertight seal. Simultaneously, the lower end of the first water-stop rubber 2 also presses against the ground, creating a watertight seal between the first water-stop rubber 2 and the ground.

[0030] Based on the first embodiment, the present invention provides a second embodiment for a dock gate for airbag launching. The first water-stop rubber 2 has first studs 51 arranged longitudinally at equal intervals at both ends. The rear end of the first studs 51 penetrates the first water-stop rubber 2 and is fixed to the dock gate body 1. A first pressure strip 52 and a first washer 53 are provided on the first studs 51, and they are fixed by a first nut 54. This facilitates the assembly and disassembly of the first water-stop rubber 2.

[0031] Based on any of the above embodiments, the present invention provides a third embodiment for a dock gate for airbag launching. The front side of the pressure pad 3 has longitudinally spaced mounting grooves 31. A third stud 61 is disposed within the mounting groove 31, and the rear end of the third stud 61 penetrates the mounting groove 31 and is fixed to the dock gate body 1. A third washer 62 is disposed on the third stud 61 and fixed by a third nut 63. This facilitates the assembly and disassembly of the pressure pad 3.

[0032] The mounting groove 31 is sealed by the cover 7. The cover 7 is restrained within the mounting groove 31 by friction.

[0033] Based on any of the above embodiments, the present invention provides a fourth embodiment of a dock gate for airbag launching. Multiple second studs 81 are equidistantly arranged at both ends of the second water-stop rubber 4.

A second pressure strip 82 and a second washer 83 are provided on the second stud 81 and fixed by a second nut 84. This facilitates the assembly and disassembly of the second water-stop rubber 4.

[0034] Based on any of the above embodiments, the present invention provides a fifth embodiment of a dock gate for airbag launching, wherein the pressure pad 3 is made of MGE engineering plastic alloy, so that the pressure pad 3 contacts the concrete retaining wall 100 to form a pressure-bearing effect, preventing the first water-stop rubber 2 from being further squeezed and possibly forming plastic deformation and causing damage.

[0035] Based on any of the above embodiments, the present invention provides a sixth embodiment of a dock gate for airbag launching, wherein the top left and right ends of the dock gate body 1 are respectively connected to the top of the concrete retaining walls 100 on both sides via first spiral buckles 91; one end of the first spiral buckle 91 is connected to the dock gate body 1 via a first ear plate A92, and the other end is connected to the concrete retaining wall 100 via a first ear plate B93.

[0036] The front side of the dock gate body 1 is connected to the dock sill 200 via the second spiral buckle 101. One end of the second spiral buckle 101 is connected to the dock gate body 1 via the second ear plate A102, and the other end is connected to the installation pit 105 of the dock sill 200 via the wire rope 103 and the second ear plate B104.

[0037] The first spiral buckle 91 and the second spiral buckle 101 can apply pressure from the dock gate body 1 to the concrete retaining wall 100 even when there is no water pressure behind it, thus ensuring that the first water-stopping rubber 2 is in a compressed state. At the same time, it can also ensure that the dock gate body 1 does not tilt outward due to typhoon.

[0038] Based on any of the above embodiments, the present invention provides a seventh embodiment of a dock gate for airbag launching. The upper end of the dock gate body 1 is a box-shaped section modulus 110, the rear end is a baffle plate 13, and the front end has a horizontal T-shaped profile 14 and a vertical T-shaped profile 15. Both the upper and lower ends of the vertical T-shaped profile 15 are connected to the dock gate body 1 via triangular elbow plates 16. The box-shaped structure at the upper end of the dock gate body 1 increases the bending section modulus, and the box body has a small draft, avoiding excessive buoyancy that could cause the dock gate to float and leak. The horizontal T-shaped profile 14 and the vertical T-shaped profile 15 can both increase the bending section modulus and reduce the weight of the box-shaped structure, while also reducing buoyancy to avoid excessive buoyancy that could cause the dock gate to float and leak. The triangular elbow plate 16 transmits the force at the end of the vertical T-shaped profile 15, preventing stress concentration.
