Description

Technical Field

[0001] The present invention relates to the technical field of geophysical logging for in-situ leaching sandstone type uranium mines, and more particularly to a cleaning device for geophysical logging cables for in-situ leaching sandstone type uranium mines. Background Art

[0002] During the exploration of in-situ sandstone uranium deposits, geophysical logging is performed to determine the location, thickness, and grade of the ore body. Logging cables transmit data and retract and extend the probe. During the logging process, the cable must be kept clean when raising and lowering the probe. This serves three main purposes: first, to prevent mud from contaminating the cable's rotating disc, potentially preventing it from malfunctioning; second, to ensure cable cleanliness and improve the accuracy of logging data; and third, to maintain a clean site for environmentally friendly exploration. Currently, manual cable cleaning is commonly used during logging. This increases the workload of workers during deephole logging in cold and hot weather, resulting in long logging times. Manual cleaning is inefficient and ineffective, impacting the accuracy of logging data. Furthermore, if the logging cable is not cleaned thoroughly for extended periods, it can be corroded by mudstone, directly shortening its service life. Furthermore, workers are located below the rig while cleaning the cable, increasing the potential for safety incidents. Therefore, it is crucial to design a geophysical logging cable cleaning device suitable for in-situ sandstone uranium deposits.

[0003] After searching, the Chinese patent application number 201922387839.6 discloses a geophysical logging cable cleaning device, which has two foldable brackets vertically welded at the center position of both ends of the water tank, and a roller is installed on each of the two foldable brackets. A motor is installed on both sides of the roller at the upper end of the foldable bracket, and a roller brush is installed on the rotor of each motor. The two roller brushes are arranged parallel to each other, and the ends of the roller brushes are connected to the foldable brackets installed on the side of the water tank body through bearings; an L-shaped foldable bracket is installed at one end of the water tank, and a water pipe is fixed at its upper end. The water pipe is located above the roller brush and parallel to the roller brush, and multiple nozzles are installed vertically downward on the water pipe; the front end of the water pipe is sealed, and the rear end is connected to one end of the hose, and the other end of the hose is connected to the water pump. The geophysical logging cable cleaning device in the above-mentioned patent has the following shortcomings: the device needs to clean the logging cable that moves laterally, and is not suitable for cleaning the logging cable that has just been pulled out of the wellhead in geophysical logging of in-situ leaching sandstone-type uranium mines. Otherwise, the cable with mud will cause the mud on the cable to splash everywhere when passing through the top and bottom pulleys, which does not meet the requirements of green and clean geological exploration; the cleaning device is relatively cumbersome, requiring two motors and water tanks and other devices, which is inconvenient to use; it is difficult to clean the mud adhered to the logging cable by relying solely on the rotating roller brush and the nozzle to spray water.

[0018] The following is combined with Figure 1 and attached Figure 2 The present invention is described in further detail.

[0019] Example: A geophysical logging cable cleaning device for in-situ leaching sandstone uranium mines, such as Figure 1 and Figure 2 As shown, it includes a water spray device, two cleaning devices and a support device. The top of the support device is fixedly installed with a foldable bracket B5 and a fixed steel frame casing 11; the foldable bracket B5 is connected by a foldable retractable support welded on the side wall of the fixed steel frame casing 11. When in use, the support can be opened to facilitate movement and carrying; the two cleaning devices are as shown Figure 1 As shown, the two cleaning devices are distributed vertically, and are connected by five steel supports 2, one of which is fixedly mounted in a fixed steel frame casing 11;

[0020] The cleaning device includes a stainless steel cleaning sleeve 12 with an opening at the top and two semi-cylindrical water-permeable cottons 13 for wrapping the cable 1; Figure 2As shown, the stainless steel cleaning sleeve 12 is composed of two semi-cylindrical sleeves, and one side wall end of the two semi-cylinders is hinged; the other side wall ends of the two semi-cylinders are connected by a lock card 15 and a lock buckle 14; two water-permeable cottons 13 are respectively embedded in the sleeves of the two semi-cylinders; after the lock card 15 and the lock buckle 14 are clamped, the two water-permeable cottons 13 can wrap the cable 1, and the bottom of the fixed steel skeleton sleeve 11 and the bottom of the stainless steel cleaning sleeve 12 inside it are fixedly connected and both have openings. In this embodiment, the opening diameter of the lower end of the stainless steel cleaning sleeve 12 is slightly larger than the opening diameter of the bottom end of the fixed steel skeleton sleeve 11, so that the fixed steel skeleton sleeve 11 can support the stainless steel cleaning sleeve 12, and at the same time ensure that the stainless steel cleaning sleeve 12 is stably embedded in the fixed steel skeleton sleeve 11.

[0021] In this embodiment, the two semi-cylinders are connected by a lock card 15 and a lock buckle 14, which makes it easy to replace the water-permeable cotton 13; the water-permeable cotton 13 in the two cleaning devices are two water-permeable cottons 13 with different densities. The water-permeable cotton 13 in the lower cleaning device is mainly used to clean the mud on the cable, and the water-permeable cotton 13 in the upper cleaning device is in a dry state, which is used to quickly dry the moisture on the cable and perform a secondary cleaning on the cable; after use, the water-permeable cotton 13 can be cleaned and dried for secondary reuse of the water-permeable cotton 13.

[0022] The water spraying device is fixedly connected to the top of the foldable bracket B5. The water spraying end of the water spraying device is located between the two cleaning devices, and the water spraying direction is toward the water-permeable cotton 13 leaking out of the top of the fixed steel frame casing 11.

[0023] The water spraying device includes a nozzle 3, a hard water pipe 4 and a water supply device; the hard water pipe 4 is placed horizontally, and the side wall of the hard water pipe 4 is fixedly connected to the top of the foldable bracket B5, wherein the foldable bracket B5 is L-shaped, the end of the hard water pipe 4 is connected to the water outlet end of the water supply device, and the end of the hard water pipe 4 away from the water supply device is connected to the nozzle 3. In this embodiment, Figure 1 As shown, the sprinkler head 3 consists of a horizontally placed hard pipe and multiple sprinkler heads. The multiple sprinkler heads are equidistantly connected to the hard pipe, and the water spraying direction of the sprinkler heads is toward the permeable cotton 13 leaking out of the top of the fixed steel skeleton casing 11.

[0024] The water supply device includes a water bucket 8, two soft water pipes 6 and a small water pump 7; the outlet end of the small water pump 7 and the hard water pipe 4 are connected by one of the soft water pipes 6, the inlet end of the small water pump 7 is connected to the other soft water pipe 6, and the water inlet end of the soft water pipe 6 connected to the inlet end of the small water pump 7 is placed in the water bucket 8; in this embodiment, the small water pump 7 should not be too large to ensure that the water sprayed from the nozzle 3 is just used to clean the cable 1; when in different usage environments, the jet water flow intensity of the water pipe is adjusted taking into account the different amounts of mud on the cable 1 and the different components of other impurities.

[0025] The supporting device includes a fixed platform 10 and a foldable bracket A9, the top of the foldable bracket A9 is fixedly connected to the bottom of the fixed platform 10; the bottom of the foldable bracket B5 and the bottom of the fixed steel frame sleeve 11 are also fixedly connected to the top of the fixed platform 10.

[0026] In this embodiment, the fixed steel skeleton sleeve 11, the fixed platform 10 and the foldable bracket A9 are preferably fixed into a whole by welding to ensure the overall stability and firmness, and prevent the cable 1 from swinging and deviating from the cleaning position; the foldable bracket A9 can be rotated, folded and fixed to the bottom of the fixed platform 10.

[0027] Working principle: Before starting the geophysical logging, first fix the whole consisting of the fixed steel skeleton casing 11, the fixed platform 10, and the foldable bracket A9 above the wellhead, match the lock card 15 with the lock hole opened by the lock buckle 14, and complete the opening and closing of the stainless steel cleaning casing 12 by engaging the lock buckle 14 with the lock card 15. The lower end opening of the probe fixed steel skeleton casing 11 and the fixed platform 10 are lowered for measurement, and the logging cable 1 is automatically retracted and released by an electric winch (not marked in the figure); when the probe reaches the bottom of the borehole and is ready to be lifted up, the stainless steel cleaning casing 12 and the stainless steel cleaning casing 12 inlaid with water-permeable cotton 13 in the opened state are opened. The steel cleaning casing 12 is wrapped around the logging cable 1, which is closed and placed in the fixed steel skeleton casing 11. The small water pump 7 is turned on to make the nozzle 3 spray water directly to the position near the contact between the water-permeable cotton 13 and the logging cable 1, and then the cable 1 is started for geophysical logging (upper measurement). The water-permeable cotton 13 that has been in a soaked state can clean the logging cable 1 that is full of mud. The cleaned mud water does not need to be specially treated and can be directly discharged to the wellhead to replenish the wall protection mud in the borehole, which will not cause environmental pollution. The dry water-permeable cotton 13 in the stainless steel cleaning casing 12 can quickly dry and re-clean the cable full of water.
