AI Technical Summary
The existing sewage pit water level detection method cannot give a high signal when the detector fails, resulting in excessive liquid level that may flood the surrounding equipment and cause equipment accidents.
A high-level liquid level detection device in a sewage pit is designed, which uses a proximity switch and a metal film on a floating body. When the sewage liquid level rises, the floating body rises and triggers a high-level alarm signal of the proximity switch.
By promptly reminding operators to deal with it, we can avoid sewage overflow and prevent environmental pollution and equipment damage.

BRIEF DESCRIPTION OF THE DRAWINGS
[0016] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0018] Explanation of symbols:
[0019] 1 represents a float, 2 represents a baffle, 3 represents a proximity switch, and 4 represents a proximity switch mounting bracket. DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0022] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0023] Please refer to Figure 1 , a sewage pit high level detection device, comprising:
[0024] A proximity switch mounting bracket 4, on which a proximity switch 3 is arranged;
[0025] The float 1 has a metal film disposed on the top thereof. When the sewage level rises, the float 1 rises to a preset height, so that the proximity switch 3 detects the metal film, thereby triggering a high-level alarm signal of the proximity switch 3.
[0026] The blocking body 2 is arranged around the floating body 1 to prevent the floating body 1 from moving horizontally.
[0027] It should be noted that the float 1 is a rectangular foam box with dimensions of 150 mm in length, 100 mm in width and 50 mm in height, and a metal film with a thickness of 1 mm is attached to the top of the rectangular foam box. The blocking body is composed of 6 cylindrical iron bars with a diameter of 5 mm, which are welded together in groups of 3, and the float is placed between the two groups. The main function of the blocking body is to prevent the float from moving horizontally.
[0028] Furthermore, the proximity switch mounting bracket 4 is an L-shaped bracket with a size of 80 mm in length and 30 mm in height, and the L-shaped bracket is fixed on the edge of the gutter, and a 20 mm long and 15 mm wide iron plate is welded on the top, and a circular hole with a diameter of 10 mm is opened in the middle of the iron plate for fixing the proximity switch. The proximity switch is a Φ30 PNP type proximity switch.
[0029] The liquid level detection device of the utility model is installed on the water inlet trough near the sewage pit. When the liquid level of the sewage pit is higher than the water inlet trough, the float will rise due to buoyancy. When the float rises to a high position, the proximity switch will sense it and give a high-level signal. If the liquid level continues to rise, the float cannot rise with the rising liquid level because the proximity switch blocks the float. The high-level detection signal will always exist and will disappear only when the liquid level drops below the high-level signal, thereby maintaining a stable output of the high-level signal.
[0030] According to the specific embodiments provided by the utility model, the utility model discloses the following technical effects:
[0031] The utility model utilizes a proximity switch to detect a metal film of a floating body, and when the floating body rises to a preset height, a high-level alarm signal of the proximity switch is triggered, thereby promptly reminding an operator to handle the problem, thereby avoiding environmental pollution and equipment damage caused by sewage overflow.
[0032] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. At the same time, for those skilled in the art, according to the ideas of the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
