Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning system for a large aquarium for fish, and more particularly, to a breeding aquarium including a pond for aquaculture for breeding freshwater fish, saltwater fish and the like, and a storage aquarium for storing adult fish. It relates to a cleaning system.

[0002]

2. Description of the Related Art In a fish breeding aquarium, sediments such as feces, residual bait, and dust invading from the outside adversely affect breeding fish (cultured fish), so that periodic cleaning is required. If this cleaning is neglected, there is a risk that the reared fish (farmed fish) will be completely annihilated due to the generation of ammonia and the generation of bacterial viruses. Therefore, the cleaning method (A person), in which the brush reciprocates on the bottom to wipe off the sediment, pumps up the water outside the water tank, and the sediment flows with the water jet ejected from the tip of the hose that moves forward and backward with the traveling body. Cleaning method (B)
), A cleaning method called a siphon method (C person) that sucks the sediment manually, and a cleaning method (D person) in which a self-propelled pump suction truck runs on the bottom to vacuum the sediment (D person). Cleaning. However, the person A only has the function of the brush running down the bottom to move the sediment to both sides of the bottom, and must separately perform an operation of removing the sediment. Especially, in the summer season when the temperature is 25 to 30 degrees, if left unattended, it rots in 1 to 2 hours, and deteriorates the water quality. In the case of the person B, the sediment floats with the force of the gushing water flow, and the breeding fish (cultured fish) swallows the sediment. Freshwater fish have the property of exhaling suspended matter as an individual, but in the case of saltwater fish, since they do not have the property of exhaling suspended matter, they may harm health and even lead to death. In contrast, C
Person D and Person D can both discharge sediment. However, since the person C is manually operated, it takes much time and is not efficient. As the size of the fish breeding aquarium becomes larger, the cleaning time spent on one surface naturally increases in proportion, Especially in winter, it is a source of labor. Also, D
The person runs zigzag along the line attached to the bottom surface while the pump suction truck vacuums the water together with the sediment.
Due to the zigzag running, a large amount of water is drained together during vacuuming, lowering the water storage level and causing growth failures. As a practical matter, run the pump suction truck at a relatively high speed to track the reared fish (cultured fish). As a result, when a large stress is given or escaped, the protective film is damaged by obstacles such as the side surface of the aquarium, and causes a disease.

[0003]

As described above, the person A and the person B
Person, person C and person D only work to move the sediment to the left and right,
Create causes of corruption. Creates suspended matter and adversely affects swarmed fish (aquacultured fish). It is manually operated and workability is poor. They thin food due to stress and grow pin heads and immature fish. And so on.

The present invention has been made in view of the conventional circumstances, and an object thereof is to swiftly collect and deposit not only sediment but also fish without floating the fish without giving them stress. Another object of the present invention is to provide a cleaning system for a large fish tank that can breed and stock high-quality fish by discharging the fish to the outside.

It is configured to be capable of wiping clothes and the like and rake it up, and is detected and reciprocated each time the traveling body traveling while raked up the sediment and the attached matter at the wiping part is detected on a drain pit provided on both sides of the bottom surface. After stopping the driving of the driving mechanism for the traveling motion, there is provided detection means for driving the driving mechanism so that the traveling body travels in a direction opposite to the traveling direction. The drainage means connected to the drainage pit is opened for a predetermined time The gist of the door. A second aspect of the present invention is that the forward and backward movements of the traveling body are controlled at predetermined time intervals. A third aspect of the present invention is that the drive mechanism for reciprocating traveling movement according to the first or second aspect makes the traveling speed of the traveling body variable. The wiping portion may be anything that generates a rubbing force, such as a rubber plate, a brush, a sponge, a sponge rubber, a cloth, or the like, and is preferably a rubber plate, a brush, a sponge rubber, or the like that can be used by a repulsive force due to elastic deformation.

According to the above technical means, the following effects are obtained. (Claim 1) In the cleaning system for a large fish tank for fish, when the traveling body moves forward by the drive of the driving mechanism, the wiping unit moves forward while rubbing the bottom surface of the tank and collecting sediment and attached matter, and moves on the drain pit. When it reaches, it stops upon detection by the detection means. That is, it stops when the wiping unit reaches the drain pit. In conjunction with this, the drainage means communicating with the drainage pit opens (opens) the valve for a predetermined time and quickly discharges the sediment and the deposits collected in the drainage pit to the outside. The stopped traveling body moves back, and the wiping unit scrapes up sediments and deposits with the same abrasion force as in the forward movement, stops on the drainage pit by detecting means, and discharges the wastewater together with the wastewater from the drainage pit. I do. By repeating this reciprocating movement, the sediment and the attached matter are removed to the outside without floating and remaining. (Claim 2) The large fish tank cleaning system according to the first aspect of the present invention performs scraping and discharging of sediments and deposits at predetermined time intervals throughout the day by rubbing of the wiping unit. (Claim 3) In the cleaning system for a large fish tank for the present fish, the traveling speed of the traveling body is selected according to the nature of the type of the reared fish (cultured fish), the growing season, and the like.

The other end of the running body 1 is connected to the first fixed pulley 43a and the fourth fixed pulley 43d at the lower half 33a of the cable 33 between the lower fixed pulley 43b and the lower fixed pulley 43b.
When the speed control motor 13 moves forward and backward by being connected to the lower half portion 33a of each portion, the speed control motor 13 is pulled by the rope 33 that moves back and forth, and has the same length as the short dimension of the bottom surface a1 of the water tank A. The wiping unit 2 is reciprocated on the bottom surface a1 back and forth in the longitudinal direction. The connection between the traveling body 1 and the cable 33 is performed by connecting the L-shaped members 11 and 11 as shown in FIG.
A pair of L-shaped plates 7 and 7 are erected at the front and rear positions on the upper surface of the end so as to face each other, and L-shaped grooves 27 are provided at the same positions on the upright surfaces 17 and 17 as shown in FIG. The lower half 33a of the cable 33 inserted from the upper open end is located at the end of the horizontal groove 27b, and the lower half 33a of the cable 33 comes into contact with each of the opposing surfaces of the L-shaped plates 7, 7. Stoppers 37, 37 are provided, and each time the rope 33 is pulled in the reciprocating direction, one of the stoppers 37 comes into contact with the L-shaped plate 7 to pull the traveling body 1. When the traveling body 1 is connected to the rope 33 with this configuration, the traveling body 1 itself can be detached from the rope 33 and separately cleaned.

As shown in FIG. 4, the drainage pits 4 are formed on both sides of the bottom surface a1 of the large fish tank A over substantially the entire length in the lateral direction, and each pit guard 14 has a large number of drainage holes 14a. At the same level as the bottom surface a1.

The pit card 14 is provided with a plurality of types having a drainage hole 14a suitable for the target breeding fish (aquacultured fish) so that the breeding fish (aquacultured fish) is not sucked, and is exchanged to replace the drainage pit. 4 is covered.

As described above, the speed control motor
13 to drive the vehicle 1 to the bottom a of the large fish tank A for fish.
Detecting means 8 for stopping the drive of the speed control motor 13 which is the driving source of the traveling body 1 every time when it reaches a drain pit (hereinafter referred to as a first drain pit or a second drain pit) 4 provided on both sides of the first vehicle 1. Is provided.

As shown in FIG. 6, when the traveling body 1 has just reached the first drainage pit 4 as shown in FIG. When the mechanical switch 28 is turned on, and when the first mechanical switch 28 is turned on, the traveling is stopped, the rotation of the speed control motor 13 is reversed, and the traveling body 1 is moved backward. 2 When reaching the drainage pit 4, a second attacker (an attacker shown in FIG. 3) 38 similarly provided on the cable 33 turns on a second mechanical switch 48 such as a limit switch to rotate the speed control motor 13 forward. It is linked with the controller B so that the traveling body 1 is reciprocated on the bottom surface a1 by repeating the above operation. More specifically, a first contactor 58 and a second contactor 68 having a vertical hole for inserting the rope 33 are vertically movably inserted into the mounting base 13b of the speed control motor 13, and the first attacker 18 and the second attacker are inserted. The first contact 58 and the second contact 68, which are raised alternately at 38, are mounted on the mounting base.
By turning on the first mechanical switch 28 and the second mechanical switch 48 provided on 13b, the traveling of the traveling body 1 in the forward direction and the backward direction is stopped.

Further, the first mechanical switch 28 and the second mechanical switch 48 are both connected to the speed control motor 13 and the drainage means 5 (the drainage pipe and the electromagnetic drainage valve provided in the drainage pipe) via the control unit B. ) Is in communication with its electromagnetic drain valve 15.

The control unit B controls the speed when the traveling body 1 reaches each of the first drain pit 4 and the second drain pit 4, specifically, when the wiping unit 2 reaches the central area of the pit guard 14. After the drive of the control motor 13 is stopped, a reversing circuit for reverse rotation and a timer circuit (timer means) for automatically opening the electromagnetic drain valve 15 for a predetermined time are built in, and the valve opening time of the drain valve 15 is built in. And a control switch for automatically opening the electromagnetic drain valve 15 for a predetermined time selected by the selection switch in conjunction with the ON of the mechanical switches 28 and 48. Has become. The control unit B has a built-in variable circuit of the traveling speed of the traveling body 1, a communication circuit to a water supply valve provided in a water supply pipe, and the like, and can externally operate a selection switch associated with the variable circuit. Thus, the traveling speed of the traveling body 1 can be varied.

The detecting means 8 is a pressure detecting means for detecting the weight of the traveling body 1 which has reached the drain pit 4 without using an attacker, a contact, and a mechanical switch such as a limit switch as described above. It may be a means.

Next, the operation of the cleaning system for the large fish tank for the present fish will be described. When the main switch is turned on, the traveling body 1
Moves forward (forward) on the bottom surface a1 of the large fish tank A for fish at the set traveling speed. During this traveling, the first rubber plate 12, which is the wiping portion 2 made of an elastic member, is elastically deformed, and the bottom surface a
The vehicle 1 moves forward while collecting the deposits such as the deposits and mosses 1 and the traveling means 1 stops upon detection by the detecting means 8 when reaching the first drain pit 4. In conjunction therewith, the drainage valve 15 of the drainage means 5 communicating with the first drainage pit 4 is opened for a predetermined time, and the sediment, deposits, etc. collected in the drainage pit 4 using the head pressure are collected. The material C is forcibly discharged. The running body 1 is now a speed control motor 13
(Reverse) by the reverse rotation of, and repulsion by the elastic deformation force of the first rubber plate 12 removes deposits such as deposits and mosses on the same bottom surface and scrapes other substances as in the case of forward movement (forward). The traveling body 1 stops in the same way as when going forward, and opens the drain valve 15 of the drain means 5 communicating with the second drain pit 4 for a predetermined time. Collected materials such as sediments and deposits are quickly discharged. This reciprocating movement is repeated to clean the bottom surface a1 of the large fish tank A. Further, the first rubber plate 12 serving as the wiping unit 2 has a sharp corner edge having elastic repulsive force, so that the bottom surface a1 of the large fish tank A for fish is used.
Therefore, not only sediment but also moss and the like are surely removed.

The traveling body 1 moves forward (forward) every predetermined time.
-The reverse movement (reverse movement) may be controlled. In this case, each time the detecting means 8 detects the traveling body 1 when the wiping unit 2 reaches the first drain pit 4 and the second drain pit 4, the delay means (delay timer) is operated for a predetermined time. It is sufficient that the traveling of the traveling body 1 is stopped for a few hours (for example, several hours), and the speed control motor 13 rotates in the reverse direction so that the traveling body 1 travels in the reverse direction when the delay timer expires.

[0023]

As described above, the present invention rakes the sediment and moss (adherent matter) etc. deposited on the bottom surface due to the rubbing of the wiping part during the reciprocation of the traveling body and collects the sediment and moss (adhered matter) in the drainage pit. Because it is a cleaning system for a large fish tank that automatically discharges objects and mosses (adhered matter) from drainage means that opens for a predetermined time, it is simple and rules that do not give stress to reared fish (cultured fish) and adult fish The sediment can be effectively raked up and discharged to the outside without drastically lowering the water storage level by a typical reciprocating operation. Therefore, as described in the conventional example, the only function is to move the sediment to the left and right, thereby creating a cause of decay (person A). They produce suspended matter and have an adverse effect on bred fish (cultivated fish) that have swallowed it (Party B). It is manually operated and the workability is poor (person C). It is possible to eliminate the problems of thinning the food with stress, growing pinheads (heads), and growing immature fish (D), and stressing fish to the optimal water quality environment for the growth of reared fish (cultured fish). A new cleaning system for large fish tanks that breeds and stocks highly complete fish by managing it without giving it. In addition, if the valve opening (opening) time of the drainage means is set in proportion to the amount of sediment or moss (adherent matter) that differs depending on the season or the breeding fish (cultivated fish), the waste will be wasted. Sediments and mosses (adhered matter) collected can be reliably discharged without consuming water. In addition, when the forward and backward movements of the traveling body are controlled at predetermined time intervals, it is possible to avoid the possibility that the traveling body travels indiscriminately and stresses the reared fish (cultured fish). In addition, unnecessary driving power is not consumed.
Furthermore, if the speed of the reciprocating traveling of the traveling body, which is a simple movement, is selected in accordance with the type of the rearing fish (farmed fish), the growing season, etc., the rearing fish having a timid nature to the moving object ( Speed to adapt to various conditions such as breeding fish (cultivated fish), which has learning ability for moving fish and moving body, and is quick to get used to, and furthermore, breeding fish (cultured fish) with different characteristics between young fish and adult fish. The sediment and moss (adhered matter) can be effectively discharged while the traveling body is reciprocating, and is more effective in eliminating the stress caused by the moving body traveling.
If the vehicle is driven at an extremely low speed, the sediment can be scraped and discharged without giving any stress.
