Description

Technical Field

[0001] The utility model belongs to the technical field of ultrasonic induction switch protection, and in particular relates to an ultrasonic induction switch protection device. Background Art

[0002] Ultrasonic induction switches are widely used in thermal power plants because of their adjustable sensing range. At present, due to different places of use and functions, ultrasonic induction switches often need to withstand the test of various harsh environments such as rain, oil, coal ash, etc.; and regular accumulation of rain, oil, coal ash, etc. on ultrasonic induction switches will reduce their working performance and cause sudden changes in the sensing range, which will lead to frequent failures of the induction switches and affect the normal operation of the equipment. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the purpose of the utility model is to provide an ultrasonic induction switch protection device to protect the ultrasonic induction switch from being eroded by rain, oil, coal ash and the like.

[0004] The utility model solves the above problems through the following technical means:

[0005] An ultrasonic induction switch protection device comprises a base and a shielding cover fixedly connected to the base, wherein a fixing hole is provided on the base.

[0006] Furthermore, the base includes a center ring and a rotating bracket, the inner hole of the center ring is a fixed hole, the rotating bracket is provided with a rotating hole which is sleeved and assembled with the center ring, the outer wall of the center ring is fixedly provided with a ball screw, the inner wall of the rotating hole is circumferentially spaced with a plurality of grooves which match and snap-fit ​​with the ball screw, and the shielding cover is fixedly connected to the rotating bracket.

[0007] Furthermore, the shielding cover is fixedly connected to the top of the rotating bracket.

[0008] Furthermore, the shielding cover is an arc cover.

[0009] Furthermore, the shielding cover is made of stainless steel.

[0010] Furthermore, the center ring and the rotating bracket are also made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The ultrasonic induction switch protection device of the present application includes a base and a shielding cover fixedly connected to the base, and the base is provided with a fixing hole. When in use, the shielding cover shields and protects the ultrasonic induction switch, thereby preventing it from being eroded by rainwater, oil stains, coal ash, etc., and rainwater, oil stains, and coal ash are not easy to accumulate, thereby reducing the failure rate of the ultrasonic induction switch. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0014] Figure 1 It is the front view of the preferred embodiment of the utility model. DETAILED DESCRIPTION

[0015] The utility model will be described in detail below with reference to the accompanying drawings.

[0016] See also Figure 1 As shown, this embodiment discloses an ultrasonic sensor switch protection device, including a base and a shielding cover 1 fixedly connected to the base, the base is provided with a fixing hole 7; the shielding cover is an arc cover, and the shielding cover is made of stainless steel. When used, the ultrasonic sensor switch is shielded and protected by the shielding cover, so as to avoid erosion by rainwater, oil stains, coal ash, etc., and rainwater, oil stains, and coal ash are not easy to accumulate, thereby reducing the failure rate of the ultrasonic sensor switch.

[0017] As a further improvement of the above technical solution, the base includes a center ring 6 and a rotating bracket 2, the inner hole of the center ring is a fixed hole, the rotating bracket is provided with a rotating hole 5 which is sleeved and assembled with the center ring, the outer wall of the center ring is fixedly provided with a ball screw 3, the inner wall of the rotating hole is circumferentially spaced with a plurality of grooves 4 which match and engage with the ball screw, and the shielding cover is fixedly connected to the rotating bracket. The shielding cover is fixedly connected to the top of the rotating bracket. The material of the center ring and the rotating bracket is also stainless steel. When in use, the rotating bracket can be rotated so that the shielding cover is in different shielding directions to meet different shielding requirements; during the rotation adjustment process, the ball screw engages with different grooves to realize the rotation positioning of the rotating bracket.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
