Description

Technical Field

[0001] The utility model relates to the technical field of sewage detection, in particular to a mounting bracket for an online instrument of an explosion-proof inspection well for chemical sewage. Background Art

[0002] In the chemical industry, sewage explosion-proof inspection wells are important facilities for ensuring production safety and environmental protection. Because chemical wastewater may contain flammable and explosive substances, the detection end and bracket of the online instrument installed in the sewage explosion-proof inspection well, which performs online sewage detection through the detection end, must meet strict explosion-proof, corrosion-resistant and safety requirements. Traditional mounting brackets for online instrument detection ends in chemical sewage explosion-proof inspection wells are mostly made of steel. Although they are strong, they require drilling during installation and do not meet explosion-proof requirements. In addition, the brackets are easily corroded in chemical environments, resulting in damage to the bracket structure, which in turn affects the stable operation and measurement accuracy of the instrument.

[0003] Therefore, a mounting bracket for online instruments of chemical sewage explosion-proof inspection wells is needed to improve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a mounting bracket for online instruments of chemical sewage explosion-proof inspection wells, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mounting bracket for online instruments of chemical sewage explosion-proof inspection wells, comprising a detection end, the outer wall of the detection end is fixedly connected to a connecting ring by a fixing screw, the outer side of the connecting ring is fixedly connected to a symmetrically arranged fixing rod, one end of the fixing rod is hinged with a support head, a pointed head is fixed to the end of the support head, an abutment block is fixed to the upper part of the hinged end of the support head and the fixing rod, when the abutment block on the support head conflicts with the abutment block on the fixing rod, it constitutes an obstacle to the hinged rotation, so that the pointed head is pressed against the well wall while the support head and the fixing rod are in a level state.

[0006] Preferably, there are two fixing rods and two supporting heads in total.

[0007] Preferably, at least two pointed tips are provided.

[0008] Furthermore, the top ends of the pointed tips are connected in an arc line, which contacts the well wall.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model ensures the stable installation of the detection end by arranging a connecting ring on the outside of the detection end, extending the fixing rod and contacting the well wall through the pointed head. The arrangement of this device does not require drilling holes in the well wall for installation, thus meeting the explosion-proof requirements. When the device needs to be taken out, the contact between the pointed head and the well wall can be released by lifting it with force. When corroded, it can be conveniently taken out and replaced, thus ensuring the integrity of the bracket structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model provides a technical solution: Figure 1 、 2 3. A mounting bracket for an online instrument for an explosion-proof inspection well for chemical sewage, comprising a detection end 1, an outer wall of the detection end 1 being fixedly connected to a connecting ring 2 by a fixing screw 3, a fixing rod 4 being fixedly connected to the outer side of the connecting ring 2, a support head 5 being hinged at one end of the fixing rod 4, a pointed head 6 being fixed at the end of the support head 5, an abutment block 7 being fixed at the upper part of the hinged end of the support head 5 and the fixing rod 4, when the abutment block 7 on the support head 5 conflicts with the abutment block 7 on the fixing rod 4, the rotation of the hinge is blocked, so that the rotation angle of the support head 5 is limited, the support head 5 and the fixing rod 4 are in a level state, and the pointed head 6 can press against the well wall.

[0016] At least two tips 6 are provided, and the top end connecting line is an arc line, which contacts with the well wall. Multiple tips 6 increase the contact points, and the top end arc line distribution can make all tips 6 contact and press tightly with the well wall, thereby increasing the pressing force.

[0017] How to use the mounting bracket: Connect the various components, connect the connecting wire of the detection end 1 to the data receiving port, and manually pull the connecting wire (use anti-corrosion rope to bind the metal wire or use optical cable, so it is strong enough to withstand the pulling force) to lower the mounting bracket into the explosion-proof inspection well. When the detection end 1 contacts the liquid in the inspection well, use a pull rod with a hook at one end to lift the support head 5 so that the pointed ends 6 at both ends touch the well wall. Remove the pull rod with the hook and remove the connecting wire by hand. The support head 5 is subjected to the gravity of the detection end 1 and the connecting ring 2 in the middle, and the hinge point of the support head 5 and the fixed rod 4 is subjected to a downward force. The support head 5 exerts a tight pressing force on the well wall. At the same time, the abutment block 7 prevents the support head 5 from rotating at an angle, so that the support head 5 will not rotate excessively and detach from the well wall. When it is necessary to remove the mounting bracket, pull the connecting wire hard to overcome the gravity of the detection end 1 and the connecting ring 2, forcing the support head 5 to separate from the well wall. The support head 5 resumes rotation and presents a "drooping" state (such as Figure 2 As shown), the bracket can be lifted out of the inspection well and the parts that need to be replaced can be replaced.
