Description
Technical Field
The invention belongs to the technical field of environmental protection treatment equipment, and particularly relates to a synchronous detection device for the position of an underwater scraper.
Background
Chain formula mud scraper is a mud equipment of scraping under water, is applicable to the clearance work to the heavy pond bottom silt of rectangle in the sewage treatment field, and the essential element includes scraper blade and two parallel chains, and the scraper blade is striden the formula connection and is installed on two chains, drives the scraper blade through the chain from this and removes along heavy pond bottom to reach the mesh of scraping silt.
In order to ensure that the scraper operates normally and prevent accidents such as derailment of a chain or fracture of the scraper caused by deviation of the scraper, a corresponding sensing device needs to be arranged to monitor whether the scraper inclines or not. Generally, the conventional mud scraper is provided with an inductive switch underwater or close to the liquid level, but the inductive switch is easy to malfunction or damage due to the severe environment of the sewage treatment equipment, namely the service life is short, and the reliability is low. Therefore, it is necessary to develop a synchronous detecting device for the position of the squeegee with higher reliability.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a synchronous detection device for the position of an underwater scraper, which is used for solving the problem of lower reliability of the existing scraper position detection scheme.
The present invention achieves the above technical objects by the following technical means.
A synchronous detection device for the position of an underwater scraper comprises two groups of detection devices which are symmetrically arranged on two sides of a sedimentation tank; each group of detection devices comprises a guide rod and a limit switch, wherein the guide rod is vertically arranged on a bracket, the guide rod is movably connected with the bracket and can move up and down, a touch head is arranged at the bottom end of the guide rod and is used for contacting with the top end of the scraper and can be pushed by the top end of the scraper to enable the guide rod to move up; the limit switch is arranged above the guide rod through the switch seat, and when the guide rod moves upwards, the top of the guide rod can push the limit switch.
Further, the touch head is a roller.
Further, the touch head is an inclined plane or an outer convex curved surface.
Furthermore, a limiting block is arranged on the support and limits the upper limit and the lower limit of the displacement of the guide rod.
Further, the bottom end of the guide rod extends into the water, and the limit switch is located above the water surface.
The invention has the beneficial effects that:
the invention provides a synchronous detection device for the position of an underwater scraper, which is used for detecting the running state of the scraper of a mud scraper by arranging a guide rod extending into the water bottom and a limit switch positioned at a high position above the water surface.

Detailed Description
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Fig. 3 shows a photograph taken by a typical chain type mud scraper, wherein two sides of a square sedimentation tank are provided with annular chains, and scrapers are connected to the chains at the two sides and are driven by the chains to do circular translation motion similar to a conveyor belt. Because the underwater sludge is unevenly distributed, the resistance borne by the scraper is uneven, and the scraper has the risk of inclined deflection. And because the sewage is turbid and the visibility is poor, corresponding underwater sensing equipment is required to be specially arranged to find the dislocation phenomenon of the scraper in time.
The device for synchronously detecting the position of the underwater scraping plate as shown in fig. 1 and 2 comprises a guide rod 2 and a limit switch 4, wherein the guide rod 2 is arranged on a bracket 1, the guide rod 2 is vertically arranged, and the bottom end of the guide rod 2 is provided with a roller; the guide rod 2 is movably connected with the support 1 and can move up and down along the vertical direction relative to the support 1, and the support 1 is further provided with a corresponding limiting block for limiting the lower limit of the displacement of the guide rod 2, so that the guide rod 2 is prevented from completely sliding off the support 1, and the displacement upper limit can be set when necessary. The limit switch 4 is arranged above the guide rod 2 through the switch seat 3, and when the guide rod 2 moves upwards, the top of the guide rod 2 can push the limit switch 4, so that the limit switch 4 sends out a corresponding electric signal outwards.
The roller at the bottom end of the guide rod 2 is used as a touch head which is in contact with the top end of the scraper 5, and is used for being pushed by the top end of the scraper 5 when the scraper 5 passes through, so that the guide rod 2 is relatively smooth and can be lifted and moved upwards, therefore, the roller at the bottom end of the guide rod 2 can be replaced by other structures with the same function, such as a smooth inclined plane or an outer convex curved surface arranged along the moving direction of the scraper 5.
When the device is used, the bracket 1 is fixedly arranged on the side wall of the sedimentation tank, the installation height is required to enable the roller at the bottom end of the guide rod 2 to extend into sewage and touch the top end of the scraper 5, and the limit switch 4 is positioned at a high position far away from the water surface; according to the mode, two groups of underwater scraper blade position synchronous detection devices are symmetrically arranged on two sides of the sedimentation tank. When the mud scraper operates, the scraper 5 touches a roller at the bottom end of the guide rod 2 in the underwater moving process, so that the guide rod 2 moves upwards to trigger the limit switch 4; when the limit switches 4 on the two sides are triggered at the same time, the normal operation of the scraper 5 can be judged, and the offset dislocation does not occur.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
The present invention is not limited to the above-described embodiments, and any obvious modifications, substitutions or alterations can be made by those skilled in the art without departing from the spirit of the present invention.
