Description
Technical Field
[0001] The utility model belongs to the technical field of cargo ships, and particularly relates to a dust suppression device for a cargo ship cabin. Background Art
[0002] Ports are cargo transportation hubs, among which dry bulk cargo transportation is relatively common. For example, the transportation and storage process of dry bulk cargo such as coal and ore is prone to dust pollution, which is mainly manifested in the material leakage and dust generation during the loading and unloading operations of dry bulk cargo belt conveyors. The current dust suppression measures in ports include fog cannons, spraying, dust-proof net covering, and the construction of wind-proof and dust-proof nets. For trucks, dust can be suppressed by covering or sprinkling water to reduce dust.
[0003] When loading and unloading dry bulk cargo, the port cargo ship unloads the material by the claw bucket of the gantry crane from the cabin, and dust overflows from the cabin opening. There is currently no suitable solution or method for the generated dust. The cover method is used, and the cabin size is very large and there is no suitable sealing method. There was a previous plan to use a mobile bracket plus a tarpaulin method, but because the cabin size is at least 20 meters * 30 meters, the bracket is too long and too heavy, and it is difficult to move it to the ship and deploy it in the cabin. Therefore, so far, there are no dust suppression measures when unloading dry bulk cargo, and the dust is extremely high during unloading. Summary of the Invention
[0004] The purpose of the utility model is to design a dust suppression device for a cargo ship cabin, which can be improved on the basis of an existing cargo ship by adding a dust suppression device, thereby effectively reducing the area exposed by the cabin opening, thereby playing a role in reducing dust dispersion.
[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:
[0006] A cargo ship cabin dust suppression device includes a cabin, with dust suppression mechanisms installed at the front and rear ends of the cabin, the dust suppression mechanism including a first group of power parts and a plurality of unpowered parts, the first group of power parts including power guide wheels respectively arranged at the left and right edges of the cabin, a rope is provided between the two power guide wheels, the unpowered part includes unpowered pulleys respectively arranged at the left and right edges of the cabin, a rope is provided between the two unpowered pulleys, and a tarpaulin is laid on the plane formed by the plurality of ropes.
[0007] Furthermore, the unpowered pulley includes an inverted U-shaped body, which can be stuck on the edge of the cabin. A rope fixing part is provided on the top of the inverted U-shaped body, and a guide pulley is provided inside the inverted U-shaped body. When the rope is pulled inward, the lower side of the inner side and the upper side of the outer side of the inverted U-shaped body will rub against the edge of the cabin, and the ball bearing can reduce the sliding friction.
[0008] Further, the power guide wheel includes an inverted U-shaped body that can be stuck on the edge of the cabin. A rope fixing part is provided at the top of the inverted U-shaped body. A guide wheel is arranged inside the inverted U-shaped body. The output end of the motor is equipped with a driving gear, and the driving gear meshes with the gear of the guide wheel.
[0009] Further, a number of balls are provided at the bottom of the inverted U-shaped body. When ensuring the relative sliding of the lower part of the inverted U-shaped body and the edge of the cabin, the balls also prevent the inverted U-shaped body from swaying left and right.
[0010] Further, brackets are provided at the front and rear ends of the cabin, and a dust suppression mechanism is installed on the brackets. The brackets and the dust suppression mechanism form an integral part. The brackets play an auxiliary function. After docking the brackets with the cabin, it can be used smoothly without installing the dust suppression mechanism one by one on the edge of the ship.
[0011] The following beneficial effects can be obtained through the above technical solutions:
[0012] The utility model can be directly improved and upgraded on the existing open cargo ship, with low transformation cost and good use effect. By moving the front and rear of the first group of power parts, the exposed area of the cabin opening is changed, playing a role in reducing the dispersion of dust.
[0013] The advantages of the rope used in the utility model are as follows: on the one hand, the rope is much lighter in weight than a metal rod or a wooden rod. The length is adjusted according to the width of the cargo ship. The deformation and sagging of the rope do not affect the dust suppression effect, while the metal rod or wooden rod is relatively long. When it reaches more than twenty meters long, it is very heavy, easy to deform, and not easy to carry. On the other hand, the rope can be effectively connected to the tarpaulin. The flexible rope can present an arch shape and is relatively flexible to use. Since both the rope and the tarpaulin are flexible, they can be folded. After folding, the volume is small, and the quality of the rope itself is small. Therefore, it is easy to carry onto the ship and deploy on the cabin.
[0014] The power guide wheel and the unpowered pulley of the utility model are completely attached to the hull edge, with stable structure. Description of the Drawings

[0020] The following further describes the present utility model in conjunction with the accompanying drawings:
[0021] As Figure 1 shown, a schematic diagram of a dust suppression device for a cargo ship cabin is presented, including a cabin 2. A set of dust suppression mechanisms is installed at each of the front and rear ends of the cabin 2. Each set of dust suppression mechanisms includes a first set of power parts and several non-powered parts. The first set of power parts can move back and forth. The first set of power parts on the left and right sides each cover half of the cabin. Such a design reduces the walking distance of the first set of power parts on the one hand, and secondly, also reduces the number of non-powered parts in each set, making it more flexible to use. The first set of power parts includes power guide wheels 4 respectively arranged on the left and right edges of the cabin 2. The power guide wheels 4 include an inverted U-shaped body that can be stuck on the edge of the cabin 2, that is, the power guide wheels can ride on the periphery of the cabin 2. A rope fixing part is provided at the top of the inverted U-shaped body. A guide wheel 11 is provided inside the inverted U-shaped body. The output end of the motor 10 is provided with a driving gear, and the driving gear meshes with the gear of the guide wheel. Both ends of the rope 3 are respectively fixed on the fixing parts 7 of the power guide wheels 4 on both sides. The non-powered parts include non-powered pulleys 5 respectively arranged on the left and right edges of the cabin 2. The non-powered pulleys 5 include an inverted U-shaped body 6 that can be stuck on the edge of the cabin 2. A rope fixing part 7 is provided at the top of the inverted U-shaped body. A guiding pulley 8 is provided inside the inverted U-shaped body. A rope 3 is connected between the rope fixing parts of the two non-powered pulleys 5. A tarpaulin is laid on the plane formed by the several ropes 3 of each set of dust suppression mechanisms, so that the two parts of the cabin are respectively covered by the tarpaulin.
[0022] For example, taking the rear part of the cabin 2 as an example, if the motor rotates forward, the first set of power parts moves forward (towards the middle part of the cabin), the first set of power parts pulls the tarpaulin, and the tarpaulin drives several non-powered parts to slide, so that the tarpaulin unfolds to cover the rear part of the cabin 2. If the motor rotates in reverse, the first set of power parts moves backward (towards the rear end of the cabin), and the movement of the first set of power parts forces the tarpaulin to fold.
[0023] Taking a cabin 20 meters wide and 30 meters long as an example. Suppose there are two dust suppression devices, each dust suppression device is 20 meters wide and has a maximum extended length of about 26 meters.
[0024] When fully extended, a rope is set every two meters. Selecting a canvas of 300 g per square meter, the total weight of the canvas used for one dust suppression device is 20 * 26 * 0.3 = 156 kg. A total of 14 sets of pulleys and 14 ropes with a length of 20 meters are provided. Suppose the weight of one rope is 1 kg. Both ends of the rope are fixed on the paired pulleys on both sides. The inward pulling force received by each pulley is about 20 * 2 * 0.3 + 1 = 13 kg. The power wheels can be powered by ship electricity, shore electricity, batteries, etc. Assuming the weight of each pulley is 1 kg, the weight of the rollers of each dust suppression device is 28 kg.
[0025] The total weight of each dust suppression device is: 156 (canvas) + 28 (rollers) + 14 (ropes) + 6 (two driving wheels) = 204 kg. Adding auxiliary devices and components, etc., it is about 240 kg. The overall weight is relatively light, and the size of the dust suppression device is properly closed after folding, and the whole volume is not too large, so it can be conveniently transported from the shore to the cabin by means of a crane or the like.
[0026] In the above embodiment, a number of balls 9 are also provided at the bottom of the inverted U-shaped body, and the two inner side walls of the inverted U-shaped body are both installed with balls 9, so that the inverted U-shaped body is closely attached to the edge of the cabin, preventing the inverted U-shaped body from swaying left and right, and the presence of the balls also ensures its smooth sliding.
[0027] In the above embodiment, it is rather troublesome to directly install each driving guide wheel 4 and idler pulley 5 on the cabin 2. The driving guide wheel 4 and the idler pulley 5 can be first installed on the bracket 1, and then the bracket is fixed at the front and rear ends of the cabin 2.
[0028] In the above embodiment, the number of idler pulleys used in the non-powered part is adaptively adjusted according to the size of the specific ship.
[0029] In the above embodiment, the positions of the front and rear two dust suppression devices can be controlled by a remote controller, leaving a gap in the middle to allow the grab to enter the cabin for operation. This technology belongs to the existing conventional technology and will not be elaborated here.
[0030] All of the above are the preferred embodiments of the present invention. For those of ordinary skill in the art of this technology, without departing from the principle of the present invention, the modifications of various equivalent forms of the present invention all fall within the protection scope of the claims attached to this application.
