Abstract
Description
Technical Field
[0001] This utility model relates to the field of mud level gauge technology, and in particular to a mud level gauge for detecting sludge ponds. Background Technology
[0002] Ultrasonic sludge level gauges, also known as ultrasonic sludge interface meters, are designed for long-term reliable operation in industrial and municipal applications. The sensor can operate when immersed in water at a depth of 5-10 cm. It uses ultrasonic emission and echo analysis of suspended solids in the water to determine the height of the sludge layer. However, existing sludge level gauges cannot automatically perform multi-point detection in sedimentation tanks during use, requiring manual adjustment of the detection position, which is not very convenient to use. Furthermore, after use, water stains are easily left on the surface of the probe, which can easily cause the probe to age and shorten its service life.
[0003] Publication (Announcement) No. CN218066662U discloses a portable sludge level gauge. Its technical solution includes: a control box and a drying box. A support column is installed in the middle of the lower surface of the control box, and a base is installed at the bottom of the support column. A pointer is installed in the middle of the bottom of the control box. A motor A is installed at the input end of the pointer at the bottom of the control box, and a rotating shaft is installed at the output end of the pointer. A support frame is installed on the top of the rotating shaft. Side plates are installed on both sides of the lower surface of the support frame, and an adjusting rod is movably installed in the middle of the side plates. This utility model solves the problems of existing devices, which cannot automatically perform multi-point detection in the sedimentation tank, requiring manual adjustment of the detection position, resulting in poor ease of use. Furthermore, after use, water stains easily remain on the surface of the probe, easily causing aging and shortening the service life of the probe. This invention improves the detection efficiency of the sludge level gauge, thereby improving its ease of use.
[0004] While the above-mentioned solutions can facilitate multi-point detection of sludge level gauges, the grounding and support of the equipment are difficult to fix, and the height extension through electric expansion joints is limited and the operating cost is high. Therefore, we propose a sludge level gauge for sludge pond detection. Utility Model Content
[0005] The main purpose of this utility model is to provide a sludge level gauge for sludge pond detection. By setting an extension unit and a limiting unit, it solves the problems of difficult operation of ground support and fixing of equipment, and the limited extension height and high operating cost of electric expansion joint.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a sludge level gauge for sludge tank detection, including a support frame in the shape of an inverted "U", a support plate in the shape of an "L" fixedly installed on one side of the top of the support frame and a detection head, and further including: an extension unit installed on the support frame and a limiting unit installed on the support plate;
[0007] The expansion unit includes a lead screw, a support block, a support block, and a support vertical rod. The support frame has a strip-shaped mounting groove on each of its opposite concave sides. The lead screw is movably mounted on one of the strip-shaped mounting grooves. There are two support blocks, each located on one of the two strip-shaped mounting grooves. One support block is threadedly connected to the lead screw. The support block is fixedly mounted between the two support blocks and extends to the outside of the support frame. The support vertical rod is embedded in the top surface of the support block, and the probe head is mounted at the bottom end of the support vertical rod.
[0008] The limiting unit includes a sliding rod, a slider, a clamping plate, a backing plate, and an adjusting bolt. A strip-shaped groove is formed on the concave surface of the top of the supporting horizontal plate. The sliding rod is fixedly mounted on the strip-shaped groove. The slider is movably mounted on the outer circumferential surface of the sliding rod. The clamping plate is fixedly mounted on the bottom surface of the slider. The backing plate is fixedly mounted on the concave surface of the top of the supporting horizontal plate and is arranged parallel to the clamping plate. The adjusting bolt is threaded to the side of the supporting horizontal plate, and its end face is connected to the side of the clamping plate through a bearing.
[0009] Preferably, the extension unit further includes a guide rod, which is fixedly mounted on another strip-shaped mounting slot and movably passes through another support block.
[0010] Preferably, a turntable is fixedly installed on the end face of the lead screw located outside the support frame.
[0011] Preferably, the supporting vertical rod and the lead screw are arranged parallel to each other.
[0012] Preferably, the adjusting bolt and the sliding rod are both arranged perpendicular to each other with the supporting vertical rod.
[0013] Preferably, an abutment pad is fixedly provided on the side of the clamping plate near the backing plate.
[0014] Compared with the prior art, the sludge level gauge for sludge pond detection of this utility model has the following beneficial effects:
[0015] 1. In this utility model, by setting an extension unit, when the equipment is placed in the sludge tank, by holding and rotating the screw above the support frame, one of the support blocks connected to the screw threadedly can be driven by force to move the support block up and down inside the support frame. The other support block can slide up and down on the guide rod to cooperate with the adjustment of the support block and provide auxiliary support. When the support block moves to the lowest point inside the support frame, the length of the support frame and the length of the support vertical rod can be used as the overall lowering height of the probe. After the support block is adjusted and moved up, the support vertical rod is driven up and placed parallel to the support frame, which can shorten the overall height of the equipment for easy storage. The equipment's extension height range is increased and the operation is flexible and convenient.
[0016] 2. In this utility model, by setting a limiting unit, when the support frame is placed into the sludge tank, the "L"-shaped support plate can be placed above the top of the sludge tank. The backing plate fixedly set on the concave surface of the top of the support plate can be placed inside the sludge tank. By maintaining the rotation of the adjusting bolts connected to the side of the support plate by the rotating thread, the adjusting bolts connected to the side of the clamp plate by the bearing at the end face can drive the clamp plate to move and adjust its position. The slider fixedly set on the top surface of the clamp plate can slide and move on the slide rod to cooperate with the clamp plate adjustment and help it maintain the placement angle. When the clamp plate and the backing plate are brought closer together, they can be clamped to the top of the sludge tank to complete the fixation of the equipment. The equipment is easy and stable to fix on the sludge tank. Attached Figure Description

[0048] The working principle of this utility model is as follows:
[0049] When the support frame 1 is placed into the sludge tank, the support plate 2 is placed above the top of the sludge tank. The backing plate 504, which is fixedly installed on the concave surface of the top of the support plate 2, is placed inside the sludge tank. The adjusting bolts 505, which are threaded to the side of the support plate 2 and connected to the side of the clamping plate 503 via bearings, move the clamping plate 503 to adjust its position. The slider 502, which is fixedly installed on the top surface of the clamping plate 503, slides and moves on the slider 501 to coordinate with the adjustment of the clamping plate 503 and help it maintain its placement angle. The clamping plate 503 and the backing plate 504 are brought closer together and clamped to the top of the sludge tank, completing the process. The equipment is fixed by holding the rotating screw 401 above the support frame 1. One of the support blocks 402, which is threaded to the screw 401, is subjected to force and drives the support block 403 to rise and fall inside the support frame 1. The other support block 402 slides and rises and falls on the guide rod 405 to coordinate with the adjustment of the support block 403. When the support block 403 moves to the lowest point inside the support frame 1, the length of the support frame 1 and the length of the support vertical rod 404 together serve as the lowering height of the probe head 3. After the support block 403 is adjusted and moved upward, the support vertical rod 404 is driven upward and placed parallel to the support frame 1, which can shorten the overall height of the equipment for easy storage.
