Abstract

PURPOSE:To efficiently collect suspended matter on the sea, by providing such an arrangement that a dust collecting basket suspended by parallel links is disposed in a recess in the bow, and channels opened at one end to the recess is led to a stern side hydrojet which is driven to take up water in the bow recess. CONSTITUTION:A dust collecting basket 3 suspended by parallel links 5', 6' is stored in a recess 2 formed in the bow. Water channels are opened at their one end to the inside of the recess 2 and are led at the other end to a hydrojet 23 disposed in the stern through both port and starboard side water channels 25. The hydrojet 23 which is driven by an engine 24 jets stream-water from the stern side, which is taken in through the recess 2 in the bow. With this arrangement the dust collecting ship may be propelled, and simultaneously, suspended matter on the sea may be efficiently trapped in the dust collecting basket 3 disposed in the recess 2 in the bow.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust collector used in rivers, lakes, ports, etc.

The dust collection vessels used today do not allow the collection of dust as the vessel moves forward, but when the vessel is stationary, the collected material that has been collected will fly forward due to the reaction when the vessel stops. , and collection was impossible when the ship was stopped.

The present invention has developed a dust collector without the above-mentioned drawbacks.The front part of the hull is formed into a cavity, and the dust collection capacity is maintained in a suspended state through a parallel link mechanism. A hydro jet is installed at the center of the surface, and a flow channel is provided that passes from the bottom of the chamber to both port and starboard sides, and the hydro jet is provided with a pipe opening facing the rear of the hull and a pipe opening facing inside the hull, In addition, each pipe port is provided with an opening/closing gate.

Figure 1 is a side view, Figure 2 is a plan view, where 1 is the hull, 2
is a U-shaped cavity provided in the front part of the hull 1. child\
Inside the curved chamber, a dust collecting unit 3 is provided in a suspended state via a parallel link mechanism, which will be described below.

Reference numeral 4 denotes a hanging means, which is configured as a parallel link mechanism at both sides of the upper deck of the cavity 2. i.e. 5.5' and 6.6'
The arms 5 and 5'' are arranged parallel to each other in opposing positions with the curved chamber 2 in between. At the same time, a link 9.91 is provided between both shafts 7.8 to connect them in parallel. This time 1
0a, 101) and lla, 1.1. b are hooks for hanging the dust collecting section 3, which are attached to the shafts 7 and 8, respectively.

Therefore, the lower end of the arm 5.5' is connected to the rotating shaft 1 which bridges between the bearings 12 and 12' disposed on the front edge of the deck sandwiching the palace house 2.
5, and one end of the rotation shaft 15 is greatly extended, and an arm 16 is integrally attached thereto, and the arm tip p is attached to the pinuton rod 18 of the hydraulic cylinder 17.
It becomes freely attached. In addition, 19 is hydraulic cylinder 1
This is a pedestal formed by holding the main body side of the arm 6.6 on the deck 2, and the grooves 20 and 20' are bearings that pivotally support the arm 6.6' in a swingable manner.

On the other hand, the dust collection section 3 has a rectangular frame with open front and side faces covered with a wire mesh, and a partition plate F is installed on the front side to prevent the dust from flying out after collecting the dust. -1 It is configured to be inserted from one side and closed. In addition,
” The above-mentioned hanging hook 1. Several support bars 21, 22 are cut out to engage with Oa, ]Ob and ]lla11b.

On the other hand, reference numeral 23 denotes a hydrojet L'tT disposed at the center of the rear portion of the hull 1, and is driven by a diesel engine 24 built in the mid-heat section of the hull. 25 and 2
Reference numeral 5 indicates an inflow passage for water to the hydro jet 23, which is led from the bottom of the palace 2, where the dust collecting section 3 is located, through both port and starboard sides of the bottom of the ship. 26 is a discharge pipe, and the opening facing the rear has opening/closing gooses 1-278° and 2.
7b is attached so as to be openable and closable via hydraulic cylinders 28a and 28b, and a branch pipe 29 is provided at a lower position of the limb pipe so as to face inward of the body.
0 is an opening/closing gate of a branch pipe, and 31 is a hydraulic cylinder for its operation.

In the drawing, reference numeral 32 denotes a flow velocity adjusting plate provided at the front edge of the bottom of the palace house 2, so that its inclination angle 0 can be changed as appropriate, thereby adjusting the amount of inflowing water.

The present invention has the following configuration, and in order to perform the dust collection function, a dust collection section 3 is held in the shrine house 2 via a hanging means using a parallel link mechanism, and a partition plate in front of the section 3 is provided. In order to drive the engine 24 and operate the hydro jet 23, the opening/closing gears 1-27a and 2'71) are opened.
Water flowing in from the front part of the vessel is discharged to the rear of the hull through a pipe port 26. Therefore, this causes the boat to move forward in the direction of arrow (A), and at this time remove debris such as pieces of wood floating on the water surface and in the water to be collected in Rime 3.

1. In the forward state, the opening/closing gate 30 of the branch pipe 29 is closed, but if the goo A is removed to open it, the waste water from the hydro jet 23 will be sprayed in the opposite direction to the traveling direction. As a result, the ship comes to a stop at that spot, but since water continues to flow in from the front of the ship, the collection of garbage continues, and the ship stops at that point. This prevents the collected material in the dust collecting section 3 from flowing out from inside the section. In addition, when moving the ship astern, the gates 27a and 27b should be closed and the gates 1-1 and 27b should be closed.
30 grooves are opened, however, a partition plate F is provided on the front part of the dust collection section 3.

When the dust is collected in the dust collection section 3 in this manner, the front part of the dust collection unit 3 is closed by the partition plate F, and the hydraulic cylinder 17 is operated at the embankment or quay. As a result, the hanging means 4 holds the dust collection node 3 in a suspended state by the action of the parallel link mechanism as shown by the dashed line in the figure (rotates in an arc, and the dust collection node 3 is dried on land. be.

FIG. 3 shows an example of use in a dam, where 33 is an incline. child! Incline 33 stand 3
4 is formed in the shape of a staircase with two steps below the bottom step, and the hull 1 is stopped (6) above the lower step A, and in this state, the collection section 3 is suspended one step above. It is meant to be transported.

The dust collection vessel of the present invention is able to efficiently collect dust not only when it is moving but also when it is stopped, and it is also very effective because it can take out the collected dust proportionately and quickly. It is something that forces you to do something.
