Abstract

PURPOSE:To exchange an underwater light source safely and easily by providing a suspension means which is made freely movable upward and downward along a stanchion in a vertical direction and suspends the underwater light source via a holder and a elevating mechanism which inserts and removes the underwater light source in and from a tank. CONSTITUTION:When an underwater light source 18 in a tank 11 is broken, an electric motor 40 of a hoisting machine 41 is operated, then a winding drum 39 rotates and begins to wind up a wire 36. A suspension means 31 connecting to the wire 36 is guided by a sliding member 29 fitted to a guiding rod 26 and is moved upward vertically. The light source 18 suspended by the means 31 is pulled above the tank 11 through an opening part 16. Since the light source 18 is coupled directly to the means 31 which moves upward or downward by maintaining the vertical state along the rod 26, the light source does not rock laterally and does not beat the mouth edge of the part 16 or abut thereon.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light source exchanger that is immersed in water in a tank and used when exchanging the light sources in, for example, an ultraviolet irradiation device for fisheries treatment. . - UV irradiation equipment line for water J611, as shown in Figure 1;
The water to be treated is accommodated in a tank 3' having a lower IIKtIL water OJ and an upper IIK flow asE j . 9. The upper IIK of the O tank 1 is provided with 7 tubes 1, and this 7 tube tube iK is equipped with an underwater light source such as a straight mercury tube 1 via a hole 1. and,
The lamp holder installed on the inner bottom 11 of the underwater light source C beams 1 is mounted vertically by having its lower end supported on the body I, and irradiates the Asahi Weir water in the tank S with ultraviolet rays. The system is designed to perform hydrogeography.

' However, the underwater light source C was damaged and deteriorated over time, and the underwater light source 6 had to be replaced by the Maruba Association, but this underwater light source e uses a straight mercury rung. 9111 [To
Ru. Conventionally, a pulley 10 is attached to the ceiling 9, and the m- of the wire 10a stretched around the pulley 10 is connected to the holder 1 of the underwater light source 6 so that the operator can pull it up. I'm doing it. However, at this time, the underwater light source d force f
In the 9th stage of horizontal shaking, drain the water to be treated in tank 1,
When a worker enters the tank 1, it is necessary to stop receiving the underwater light source 6 and pull it up while guiding it.
At times, a helper is also required for installation.

Therefore, replacing the underwater light source requires a lot of effort and is also dangerous, so improvements are desired.

This invention was made in view of the above circumstances, and its purpose is to automatically raise and lower an underwater light source using a lifting mechanism, thereby increasing the capacity and safety of underwater exchange work. The aim is to provide a light source exchanger that can

The present invention will be described below based on an embodiment shown in the drawings. In Figure 2, 11 is the tank of the ultraviolet irradiation device for water escape, and there is a water outlet is at the bottom.

An outflow port IJ is provided at the top, and the water to be treated 14 is inside.
An opening l# having a flange IJ is provided on the upper surface of this tank 11, and a lamp holder body 1r is provided at the inner bottom of the tank 11 facing this opening s16. Ru. The underwater light @III consisting of a straight mercury tube inside the tank 11 is covered with an iron layer while being immersed in the water to be treated 74. That is, the underwater light source 1a/ri straight tube-shaped rung main body 19 and the holder 21 connected to the upper end of the rung main body 19 via the amegeta 20 are connected to each other. As shown in FIG. 4, a mounting 7 flange 2S having mounting holes zx and xz is provided. And this installation 7
Attach the lunge 23 to the hanging tool described later, and
The underwater light source 18 is vertically installed in the tank 11 by supporting the lower end of the lamp holder IWK. Furthermore, a cover 16m is installed on the 7 flange 15 of the tank 11 by tightening and fixing the cover 16m with the 7 flange stsbtM lutona, to 11ie, etc., and this mounting is done by attaching the cover 16m to the 7 flange 15 of the tank 11. The plate 24 is fixed together by the above-mentioned lutners and tors 11a. (9) A support 2J, which is longer than the length of the underwater light source 18, is erected on the pace board 24. Furthermore, a guide rod 26 is attached in parallel to one side of this support 25 by supports 2F and JFK. This f-hydro, de-tgIC has two slide members 29. The rims fit together so that they can be raised and lowered freely.

(7) Sufu (P member 29.1911C has mounting pieces 10°30 protruding from it, and these mounting pieces so, s.

A hanging tool S1 facing the upper end surface of the underwater light source 110 is attached to the. This suspension AJJ consists of a cylindrical sJ2 and an Ii connection 7 flange 33 provided at its lower end, and this connection flange 33 has mounting holes zx and 11 that are opposite to each other provided in the attachment 7 flange 23 of the underwater light source 18. Mounting hole 34.
34 are provided and are removably connected by a delt nut S5.

Further, one end of a wire 35 is connected to the upper end of this hanging tool 31, and a pulley z is connected to extend the expanded wire 3# to the upper end of the support 25 and the upper end of the guide rod 2C.
W, 18 are established. In addition, a machine 41 consisting of a take-up drum 3# and an electric @40 connected to the other end of the wire J6 is provided on the pace plate 24, and
A lifting mechanism 42 is configured to raise and lower J via a wire Jσ.

Next, the operation of the nine-way exchange machine constructed as described above will be explained. If the underwater light source 1# installed in the tank 11 is damaged and needs to be replaced with a new one, first operate the electric motor 40 of the winder 41.
Then, turn the take-up side rack 111 and start taking up wire J#70S. Then, hang the wire s g+=at ^
31 is a slide member z that fits into the guide rod 2iK
The fist that rises vertically guided by s and xe is therefore suspended from the hanging holder 31.
It is pulled up above the tank 11 from there. At this time, the underwater light source 1# Tsusono Hole 21 is f&
It is directly connected to the hanging tool 11 that moves up and down while maintaining a vertical layer.
IN! There is no need to touch or expose the underwater light source 11 to the top of the tank 11 in this way. After that, remove only the lamp body 1# from the A/F 2o and install a new one. Replace with main body number. Next, electric motor 4
Reverse o, wire 3C wire winding drum s9 to e
The light source 1# out of the nine is directly connected to the hanging holder 31 and lowered along the do 2c. When the lower end of the underwater light source 18 is inserted into the body 11, the operation for replacing the underwater light source 18 is completed.

In the above embodiment, the hanging tool is connected to the tip of the wire, and the wire is raised and lowered by winding and unwinding, but the invention is not limited to this. - The structure of the elevating mechanism is not limited.

Of course, the present invention is not limited to ultraviolet irradiation devices for water treatment, but can be applied to nine devices equipped with a light source immersed in water.

As described above, the present invention is provided with a hanging tool that can be raised and lowered by a lifting mechanism at the top of a tank, and an underwater light source is connected to this hanging tool. The underwater light source can be replaced without draining the water in the tank. Moreover, since the lifting holder is vertically guided up and down, the underwater light source does not swing sideways when going up and down, and a caregiver can attach it to the specified position without guiding it inside the tank, improving safety and making work easier. This has the effect of making it easier.
