Description

[Detailed explanation of the invention] A. Purpose of the invention a. Industrial application field This invention is used to remove foreign matter such as sludge or solid matter when the drain pipes of houses, factories, etc. are clogged with foreign matter, such as sludge or solid matter. The invention relates to a device.

b. Prior Art Drainage pipes require bent or branched parts in their construction, and L-shaped joints, T-shaped joints, etc. are used, which impairs drainage at those parts and causes blockages. In addition, even underground drainage facilities made of clay pipes or bricks often become clogged.

Therefore, for example, for drain pipes from kitchen sinks, baths, toilets, etc., it is common practice to install a sewage basin (sewage pool) at the first turning point outdoors, and use it to scoop out sludge and other foreign substances. It is true.

C. Problems that the invention aims to solve Even if a sewage basin is installed as described above and foreign matter is scooped out from there, the foreign matter may become clogged in the underground drainage pipes leading to it. In addition, if the drainage pipes that connect the sewage basin are poorly constructed, the drainage will be even worse, and sludge will accumulate in the sewage basin and the drain pipe, and will settle and harden. Furthermore, in condominiums and other housing complexes, drainage pipes are installed inside the buildings, and foreign matter may become clogged in the middle of the drainage pipes. Moreover, if the drain pipe is long and there is no support along the way, it will sag downward and sludge will settle and harden in that part.

In such cases, conventional methods include high-pressure water spraying, vacuum suction, extrusion using split bamboo, and melting and removal using soluble soda or other chemicals. However, the above-mentioned high-pressure water spray and vacuum suction means require large-scale equipment, and the cost is quite high except for special cases of clogging. Furthermore, the method of using split bamboo has limitations on its length, and there are some cases where it is clogged with foreign matter that cannot be removed by using split bamboo. Furthermore, depending on the material of the drain pipe, methods that use chemicals may corrode the inner surface and may not be usable, and some foreign substances may not be removed.
Moreover, there are problems such as the fact that using a large amount may have an adverse effect on subsequent wastewater purification treatment.

The present invention relates to a device for removing foreign matter in a drain pipe, and is an attempt to solve the above-mentioned problems of the conventional device. In other words, the purpose of this invention is to
Even if a foreign object becomes clogged in the middle of a drain pipe that cannot be seen visually, the relatively simple structure can almost completely remove foreign objects that are clogged deep inside a bent drain pipe or are difficult to remove. To provide a device for removing foreign matter in a drain pipe that does not adversely affect wastewater purification treatment.

B. Configuration a. Means for solving the problem The device for removing foreign matter in a drain pipe of the present invention has a foreign matter removal operating section A at the end, an operating section B at hand, and a wire that connects both A and B. Consisting of tube C,
The actuating section A rotatably supports an intermediate part of a pair of clamping plates 2 with a clamping part 3 on the inside of the tip on a support arm member 1 attached to the front part of the tube C, and the clamping part 3 is The tube C can be opened and closed via the wire 5 inside the tube C, and a harpoon-like member 6 is attached to the clamping plate 2 so that it protrudes forward when the tube C is opened. The operating part B is a gripping cylinder 7 attached to the rear part of the tube C.
It is provided with a lever 8 for operating the wire 5 and a handle 9 for rotating the operating section.

In the above structure, the actuating part A is made of metal, for example, stainless steel, and the supporting arm members 1 thereof are provided facing each other with an extension line x of the center line of the tube C in between, as shown in the illustrated example. In this case,
It is desirable to form two sets orthogonally, and it is preferable that the base 10 thereof be formed into a pipe shape and removably fitted in the front part of the tube C.

The clamping plates 1 consist of a pair, each intermediate portion is supported by four shafts on the opposing arm member 1, and the inner side of the opposing tip is formed into a clamping part 3 having unevenness, for example, so that it can come into contact when the mouth is closed. Further, in order to open and close the holding part 3, for example, as shown in the illustrated example, the shaft 4 to the arm member 1 is
A torsion coil spring 11 is placed in the sleeve, and the front end sides of the clamping plate 1 are opened laterally. Then, the wire 5 connected to the clamping plate 1 is moved back against the force of the spring 11 using the operating portion B at hand via the tube C to close the opening.

Furthermore, the clamping plate 2 is equipped with a harpoon-shaped member 6 toward the front so that the clamping part 3 opens and projects when the base 12 moves forward, for example, as shown in the figure. Preferably, the member 6 is removable. Furthermore, the holding plate 2 has a blade portion 15 whose outer edge comes into contact with the inner circumferential surface of the drain pipe 13 when the holding plate 2 is opened to scrape off adhering foreign matter 14. As shown in FIG. 4, the side surface 16 of the clamping plate 2 is preferably twisted into a screw shape in order to send backward the sludge-like foreign matter 14 that hits the side surface during rotation.

The tube C has flexibility that can accommodate the bending of the drain pipe 13, and the feeding part of the operating part A and the operating part B.
It is necessary to use a material having elasticity to rotate the cylinder body 7 and rotate the actuating part A when the cylinder body 7 is rotated, such as synthetic resin or synthetic rubber having soft elasticity. For example, one containing steel wire may be used except for the part near the tip. The wire 5 may be made of twisted thin steel wires, for example, and is slidable within the tube C.

The lever 8 of the operation part B is used to close the clamping part 3 by pulling the wire 5 toward the hand, and to open the clamping part 3 by pushing it forward. For example, a locking slot 17 is formed to lock at each position. However, a spring 11 for opening is provided on the holding plate 2 as shown in the illustrated example, and a spring 16 is attached to the operating part B to pull the wire 5 toward the hand with a force stronger than the spring 11 as shown in FIG.
may be provided. In this case, the role of lever 8 is to
By pushing it forward, the wire 5 is loosened forward against the strong spring 16 of the operation part B, and the clamping part 3 can be opened. The handle 9 may rotate the actuating portion A via the tube C. Note that, unlike the illustrated example, the clamping plate 2 can also be pivoted so that it can rotate in a manner such that it crosses at the middle part, for example like Western scissors, so that when the rear part is closed, the previous clamping part also closes. It is.

b. Effect The usage and operating conditions of the present invention are as follows.

In use, the operating part A of this foreign matter removing device is sent into the drain pipe 13 through the tube C. In this case, if the lever 8 of the operating part B is locked near the hand and the wire 5 is moved backward, the clamping part 3 of the operating part A is in the closed state. Therefore, tube C
Since it is flexible, it can easily reach the back even when the drain pipe 13 is bent.

When the clamping plate 2 of the operating part A reaches the position where various foreign objects 14 are clogged in the drain pipe 13, the second
As shown in FIG. 5, push the lever 8 of the operating section B forward to move the wire 5 forward. As a result, the holding part 3 opens as shown in FIGS. 1, 3, and 5, and at the same time, the harpoon-like member 6 protrudes forward as the base 12 of the holding plate 2 moves forward, and, for example, the harpoon-like member 6 protrudes forward. A foreign object 14 like this is pierced. Next, as shown in FIG. 6, by pulling the lever 8 of the operating part B toward the hand and retracting the wire 5, the clamping part 3, which had been opened as described above, is closed.
grips the solid foreign object 14.

In this state, if the actuating part A is pulled closer to you through the tube C and taken out of the drain pipe 13, the foreign object 14 stuck in the harpoon-like member 6 or the foreign object 14 held by the clamping part 3 will be removed from the drain pipe 13. It will be pulled out and removed.

Furthermore, when the gripping part 3 of the operating part A is opened, when the handle 9 of the operating part B is rotated and pulled out, the outer edge of the gripping plate 2 comes into contact with the inner circumferential surface of the drain pipe 13, so that the blade The foreign matter 14 attached to the inner circumferential surface is scraped off by the portion 15 and can be taken out.

If the side surface 16 of the clamping plate 2 has a screw-like twisted shape as shown in FIG.
The sludge-like foreign matter 14 is sequentially sent out to the user's hand by the holding plate 2 and can be taken out. Furthermore, as shown in FIG. 2, if the operating part B is provided with a spring 16 for retracting the wire 5, the force of the spring 16 will close the clamping part 3 and grip the foreign object 14 without force, so that foreign objects such as glass bottles can be broken. It becomes difficult.

C. Effect of the invention As is clear from the above, the present invention, when a foreign object is clogged deep inside the drain pipe, connects the actuating part at the front end through a flexible tube, without causing problems with the bent part of the drain pipe. can be sent.

When the actuating section reaches a position where a foreign object is stuck, the harpoon-like member can pierce and lock the foreign object, such as paper, cloth, or board, by opening the clamping section. Subsequently, by closing the clamping part, the clamping part can clamp the stuck foreign object. By pulling out the operating portion, foreign objects stuck in the harpoon-like member or caught in the clamping portion can be easily taken out of the drain pipe.

Also, if foreign matter is attached to the inner circumferential surface of the drain pipe, feed the actuating part and keep the clamping part open.
By rotating the actuating part and pulling it out toward your hand, you can remove the foreign object while scraping it off with the blades on the outer surface of the clamping part.

Furthermore, as in the illustrated embodiment, if the side surface of the clamping plate of the actuating section is twisted like a screw, foreign matter such as sludge can be removed from the side surface of the clamping plate by rotating and pulling out the clamping plate. It is sent to the hand side sequentially along the line and can be easily removed.
