Description

Technical Field

[0001] This utility model relates to the field of hydrological monitoring technology, and more specifically, to a hydrological monitoring wellhead protection device. Background Technology

[0002] Hydrological monitoring wellheads are important channels for collecting hydrological data such as groundwater and rivers. Protective devices can prevent debris from falling in, human damage, or accidental falls, and ensure the normal operation of monitoring equipment. Traditional wellhead protective devices are mostly simple iron well covers, which are prone to rust and corrosion and are difficult to open after long-term use.

[0003] Traditional protection devices are mostly of fixed size, which cannot flexibly adjust the protection range according to the depth of the wellhead. They have poor coverage for wellheads of different specifications and are prone to inadequate protection. The cover plate and the protective barrel are mostly fixed with bolts, which require alignment with multiple holes during installation. During disassembly, they are difficult to unscrew due to rust, resulting in time-consuming and laborious maintenance or equipment repair, and prolonging the exposure time of the wellhead. The power cords and signal cables of the monitoring instruments are not properly fixed, and are easily tangled, worn or soaked in water, affecting the stability of data transmission and even causing equipment failure.

[0014] The present invention is further provided that the wiring block is provided with a wire-passing groove, which facilitates the wires to be passed through the wiring rack.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a hydrological monitoring wellhead protection device, which has the following beneficial effects:

[0017] 1. By rotating the adjusting screw, the adjusting plate is driven to rise and fall along the adjusting slide, which drives the extension bucket to extend and retract inside the protective bucket. It can be adapted to monitoring wells with large depth differences, eliminating the need to customize equipment for different wellheads, thus reducing procurement costs. At the same time, the extension bucket can serve as a base for equipment installation, and with the adjusted height, the sensor is always in the optimal monitoring position.

[0018] 2. During installation, the mounting block is inserted along the sliding groove, the fixed handle is rotated and steered, and the mounting gear, in conjunction with the mounting ring, drives the mounting block to lock vertically, thus completing the fixing of the cover plate. Disassembly is performed by reversing the operation, eliminating the need to deal with rusted bolts. Compared with the traditional structure, it improves maintenance efficiency, can be operated by a single person, and reduces the exposure time of the wellhead.

[0019] 3. The wiring block clamps the cable with the elastic force of the wiring spring to prevent the cable from loosening or abrading due to water flow impact or vibration. The conduit and wiring device work together to guide the cable to the outside of the well opening to avoid tangling and knotting. Attached Figure Description

[0030] In this embodiment, the protective bucket 1 is placed at the hydrological monitoring wellhead. When protecting the wellhead, the cover plate 2 is fastened to the protective bucket 1 to protect it. When connecting the cover plate 2 and the protective bucket 1, the mounting block 10 is aligned with the sliding groove 7, and the mounting rod 4 and fixing rod 5 are inserted into the mounting sleeve 3. When the mounting block 10 slides to the bottom of the sliding groove 7, the fixing handle 6 is rotated, causing the mounting block 10 to move into the turning groove 8. Subsequently, the mounting toothed ring 19 is rotated via the mounting ring 20, and the mounting toothed ring 19 engages with the mounting toothed ring. The gear 18 engages with the mounting gear 18, which drives the mounting screw 17 to rotate. The mounting screw 17 drives the mounting block 10 to move vertically, so that the mounting block 10 extends into the fixing groove 9, thereby fixing the position of the mounting sleeve 3 and the fixing rod 5, which facilitates the connection of the protective bucket 1 and the cover plate 2. When the cover plate 2 is removed, the mounting ring 20 is reversed, so that the mounting block 10 moves downward into the turning groove 8. The fixing handle 6 is reversed, so that the adjusting plate 13 is aligned with the sliding groove 7. The cover plate 2 and the mounting sleeve 3 are moved outward, so that the cover plate 2 can be removed.

[0031] Please see Figures 2-3As one embodiment of the wiring device: the protective barrel 1 is provided with a conduit 22, the wiring device includes a wiring frame 23, the wiring frame 23 is installed in the extension barrel 11 and the protective barrel 1 by bolts, the wiring frame 23 is slidably provided with a wiring rod 24, one end of the wiring rod 24 is provided with a wiring block 25, the wiring block 25 is provided with a wiring hole 26, a wiring spring 27 is provided between the wiring block 25 and the wiring frame 23, and the wiring block 25 is provided with a wire groove 28.

When the cover plate 2 is removed, the mounting ring 20 is reversed, so that the mounting block 10 moves downward into the turning groove 8. The fixing handle 6 is reversed, so that the adjusting plate 13 is aligned with the sliding groove 7. The cover plate 2 and the mounting sleeve 3 are moved outward, so that the cover plate 2 can be removed.

[0034] Depending on the depth to be protected at the wellhead, rotate the adjusting screw 14. The adjusting screw 14 can be rotated using a handle or screwdriver. Through the threaded engagement between the adjusting screw 14 and the adjusting plate 13, the adjusting plate 13 is moved along the adjusting slide rod 15. The adjusting plate 13 moves the extension barrel 11 vertically. The hydrological monitoring equipment can be mounted on the extension barrel 11 via a bracket or directly installed inside the monitoring well. The power cord, signal cord, and indicator light of the hydrological monitoring instrument are fixed by a wiring device and connected to an external power source or instrument via a conduit 22.
